The purpose of the study was to evaluate the occurrence and range of refractive errors in dogs of different ages. A total of 99 clinically healthy, mixed-breed mesocephalic dogs were included in the study and divided into three different age groups according to the current human/pet analogy chart: 40 adults (23 males, 17 females, 1–8 years old, 3–70 kg), 21 seniors (14 males, 7 females, 6–11 years old, 7–42 kg), and 38 geriatrics (22 males, 16 females, 8–13 years old, 5–45 kg). All the dogs underwent an ophthalmic examination, including Schirmer tear test, tonometry, biomicroscopy, and ophthalmoscopy. Neither eye drops nor pharmacological sedatives were administered before the autorefractometry. The refractive states were assessed bilaterally using a hand-held Retinomax 3 (Righton) autorefractor. The results underwent statistical analysis using Statistica v12 software (ANOVA and t-test). A P-value < 0.05 was considered as significant. Emmetropia, defined as a refractive state > −0.5 D and < +0.5 D, was found in 36% of the adult, 43% of the senior, and 38% of the geriatric patients. Anisometropia was found in 1% of the adult, 9.5% of the senior and 5.5% of the geriatric dogs when the refractive power of the two eyes differed ≥ 1.0 myopia ≤ −0.5 D and hyperopia ≥ +0.5 D were found in 23% and 41% of the adult eye globes as well as 24% and 33% in the senior dogs and 15% and 47% in the geriatric dogs, respectively. The maximal values of the myopia in the adult and geriatric dogs were −2.5 D and −2.75 D, respectively. The maximal values of the hyperopia in the adult and geriatric dogs were 1.75 D and 2.5 D, respectively. No statistically significant correlation was found between the groups. Ametropia is a common refractive state for dogs of different ages. The most frequent refractive state in ametropic mixed-bed dogs in all age groups is hyperopia.

Forest structure is a key component of its management and assessment in every forest ecosystem. In the study, 23 plots were established to obtain data on the acacia forest community based on tree size. Results from the study indicated that the acacia community could be broadly divided into two groups based on tree-size variables. The diameter and height frequency distributions of Group 1 were right-skewed, while those of Group 2 were more complicated. In both groups, there were positive correlations between tree-size variables, nonetheless the relationship between diameter at breast height and total height was best described using the cubic equation. Further, the Weibull and Sinh-Arcsinh (SHASH) best simulated the diameter and height frequency distribution. High-quality trees were found in a large diameter (> 30 cm) and height groups (> 22 m). In contrast, low-quality plants often concentrated on the smallest sizes. Therefore, trees with a diameter of 2–10 cm and a height lower than 8 m should receive attention to tend. Carbon stock in the two groups was 61.48 Mg·ha^–1 and 64.21 Mg·ha^–1, respectively. Tending solutions and measurements should be carried out regularly to promptly propose silvicultural measures and improve forest quality in future.

3D printing is widely used method. In the term of developing of components for electronic devices, it is important to provide the good physical properties of the used dielectric. The main parameters are optional and stable value of the relative permittivity and the minimum dielectric losses of the material. The paper is focused on testing of loss factor and relative permittivity of following materials: polylactic acid (PLA, in two dye modifications), polyethylene terephthalateglycol (PET- G) and acrylonitrile butadiene styrene (ABS) in the frequency range of 1-100 MHz. It was proven, that the values of permittivity of the tested materials were 2.9-4.2 and loss factor 0.8-4%. Concerning relative permittivity, the tendency to mild linear drop of relation was observed by increasing frequency, especially expressed in PLA materials. In loss factor, PLA materials displayed increasing values with increasing frequency, whereas the declining curve was observed in PET-G. Absolute value of ABS loss factor varied between 0.9-1.5%. The reasonable influence of added dyes was found out.

The purpose of this paper is to evaluate current nutritional guidelines of modern diets based on medical and nutrition facts and their effect on gut microbiota and health, considering current recommendations of world authorities such as FAO and WHO. For this purpose, the first part is devoted to the impact of microbiota on human health, and special attention is committed to the effect of fibre on gut microbiota. The second part is dedicated to the fundamental division of diets and the evaluation of concrete nutritional guidelines of modern diets into microbiota and health, followed by the recommendations of global authorities. Modern diets include diets from the point of view of medical science (e.g. Mediterranean), promoted by nutritionists and authorities (e.g. Nordic) and by social trends (e.g. vegan). The evaluation summarises that high-fibre diets have tremendous benefits on human health. Diets with fresh, local and naturally fermented food positively impact the gut microbiota, hence human health (agrarian diets). The results of the review show that the nutritional guidelines associated with the lowest mortality are the Mediterranean with the Atlantic or Nordic diet, which is in line with the recommendation of the world authorities (FAO, WHO, UN). The low-fibre western diet with highly processed foods with no or very low levels of live bacteria appears to be high-risk in terms of preventing civilisation diseases with a negative impact on gut microbiota, which is in line with current FAO and WHO guidelines.

Common bean (Phaseolus vulgaris L.) is one of the most important grain legume foods for the human diet. Common bean seed is gaining attention due to its content of secondary metabolites with positive effects on human health. The present work analysed the effect of common bean germination on the essential amino acid profile, active compound content, and expansion index after extrusion processing. The content of tryptophan (Trp) in raw common bean (RCB) and in germinated common bean (GCB) seeds was 6.1 and 7.9 mg·g^–1 of protein, respectively. The limiting amino acids in RCB were sulphur amino acids and Trp, and in GCB only the sulphur amino acids were the limiting amino acids. The germination process in beans increases the levels of quercetin and kaempferol and allows the synthesis of daidzein and genistein, and significantly increases the expansion index after extrusion processing. The germination of common bean could be used as a strategy to improve nutritional, nutraceutical, and processing properties.

This study aimed to observe the lingual morphology of the domesticated Asian small-clawed otter, Aonyx cinereus (A. cinereus), from Yogyakarta, Indonesia. Six domesticated A. cinereus adults were obtained from a local otter breeder in Yogyakarta, without regard to gender. The animals were acclimated to the laboratory for one day, followed by macroscopy identification and scanning electron microscopy (SEM) and light microscopy (LM) analysis. Macroscopically, the tongue of domesticated A. cinereus is divided into three parts: the apex, corpus and radix. The apex is the shortest part and can move freely. A median groove is bent along the corpus. Typically, the radix contains circumvallate papillae and the valleculae epiglottis. SEM and LM observations revealed that the lingual morphology of A. cinereus consisted of two types of papillae: mechanic papillae (horny filiform, leaf-like filiform, bifid filiform, trifid filiform, elongated leaf-like filiform, triangular filiform and conical papillae) and gustatory papillae (fungiform and circumvallate papillae). The lingual glands consists of Weber’s glands and von Ebner’s glands, which secrete acid and neutral mucins. Collagen fibre is found in the lamina propria and muscular layer. In conclusion, the papillae of the Asian short-clawed otter have the same structure as those of other Mustelidae family members.

Mercury belongs among the highly hazardous substances present in the environment and represents a great health risk for many animals including predatory and piscivorous birds. The aim of this study was to assess the total mercury content in the main detoxifying organs (liver and kidney) and in the muscles of adult great cormorants (Phalacrocorax carbo) caught at two localities (the Krogulna ponds and the Nysa Kłodzka River) in southern Poland. The aim was to compare the locality with the iron ore mining history (the Krogulna ponds) with a site without such load (the Nysa Kłodzka River). The total mercury content in the great cormorants decreases as follows: kidneys > liver > muscle in both monitored localities and significantly differs between the localities. The average mercury content varied from 0.58 ± 0.38 mg/kg (muscle) to 1.39 ± 1.42 mg/kg (kidney) in the cormorant from the Krogulna ponds and from 1.09 ± 0.40 mg/kg (muscle) to 3.12 ± 1.55 mg/kg (kidney) in the cormorant from the Nysa Kłodzka River. The accumulation of mercury does not correlate with the mining history as it was higher at the Nysa Kłodzka River, but it is probably influenced by the different fish stocks in these two localities (omnivorous fish in the Krogulna ponds versus predatory fish in the Nysa Kłodzka River).

Today, there is widespread concern about the potential health effects on populations from consuming contaminated leafy plants and vegetables. In this study, heavy metal content is present in commonly consumed leafy plants (Atriplex hortensis, Spinacia oleracea, Urtica dioica, Beta vulgaris, and Brassica oleracea) from the mining area near Tuzla in Bosnia and Herzegovina was determined. After the preparation of the samples by wet digestion with HNO3, the flame and graphite furnace atomic absorption spectrometry was used. According to the results, the lowest concentration in leafy plants was obtained for Cr 0.08 mg/kg (Brassica oleracea) and the highest for Fe 539.15 mg/kg (Spinacia oleracea). The novelty of this study was to estimate health risk assessment for selected leafy plants. The estimated daily intake (EDI) of Pb, Mn, Zn, and Cd from consuming leafy plants was higher than the maximum tolerated daily intake. For adults, the total target hazard quotient (THQ) calculated based on EDI of the heavy metals was found to be > 1 for Pb and Cd due to all leafy plant consumption and for the children risk level of THQ was observed for most heavy metals. The hazard index due to the intake of toxic metals from ingesting leafy plants was much > 1. According to the total carcinogenic risk index for adults and children, the carcinogenic risks for all samples were higher than the tolerable range. Based on the results of this study, there is a significant non-carcinogenic and carcinogenic health risk to the population associated with the consumption of leafy plants cultivated in the mining area.

Previous studies of the effects of elevated CO₂ (eCO₂) concentrations and heavy metal stress conditions on plant growth and physiology have mostly focused on crops rather than vegetables. In this study, we investigated the effects of Cd stress on the growth and antioxidant system of pak choi (Brassica rapa L.), water spinach (Ipomoea aquatica Forssk.), cherry radish (Raphanus raphanistrum subsp. sativus (L.) Domin) and pepper (Capsicum annuum L.) growing in pots under ambient CO₂ (aCO₂) or eCO₂ conditions. In general, Cd stress reduced plant biomass and SPAD values under aCO₂ and eCO₂ conditions; however, the reduction was smaller under eCO₂. Cd stress significantly reduced vegetable superoxide dismutase (SOD) and catalase (CAT) activities under both aCO₂ and eCO₂ conditions; however, the decrease in cherry radish and pepper peroxidase and SOD activities and in pak choi SOD and CAT activities was significantly less under eCO₂. The Cd content of the edible parts of pak choi, water spinach and pepper was significantly lower under eCO₂ than under aCO₂. Our data suggest that eCO₂ concentrations could be beneficial for the growth of some vegetables and reduce the Cd content.

This study examined the effects of beneficial rhizobacterium Pseudomonas chlororaphis strain AFS009 and entomopathogenic fungus Beauveria bassiana strain GHA against plumeria rust Coleosporium plumeriae. Two preemptive or three curative laboratory experiments and a curative field experiment were conducted to examine the effects of these commercially available biocontrol products. Treatments included the application of B. bassiana at 1.23 g/L and P. chlororaphis at 3 or 9 g/L. Systemic fungicide azoxystrobin applied at 0.12 g/L and water were included as positive and negative controls, respectively. While its effect was insignificant in the field trial, B. bassiana reduced the rust pustule development in one of two preemptive and two of three curative laboratory trials. In contrast, P. chlororaphis applied at 9 g/L suppressed the number of rust pustules in both laboratory and field experiments, demonstrating its potential biological activity against plumeria rust. In the field trial, the effect of P. chlororaphis was observed at 14 days post-treatment, suggesting that an application interval of 14 days on infected plants can take the rust under control.

The adverse economic and social effects of the recent increases in food prices have prompted policymakers and academics to reconsider the potential causes of such increases. This paper contributes to the existing literature by investigating the causal effects of oil prices, fertiliser prices, global economic activity, and geopolitical risk on international food price volatility between January 1993 and December 2021. The research considers the aggregate food price index and the prices of various specific foods, including cereal, vegetable oils, dairy, meat, and sugar. The Glosten, Jagannathan, and Runkle-generalised autoregressive conditional heteroskedasticity (1,1) [GJR-GARCH(1,1)] model is employed to estimate the food price volatility series, while the causality-in-quantiles test is conducted to identify the drivers of food price volatility for different volatility regimes. The analysis suggests heterogeneous results regarding the significance of causal linkages. More specifically, the aggregate food price volatility is affected by oil prices, global economic activity, and geopolitical risk under different market conditions. The causality analysis also indicates that the volatility of cereal prices is the most sensitive to the four considered variables. Likewise, geopolitical risk is the most critical factor affecting all food commodities during almost all market conditions, while oil prices and global economic activity have limited predictive power. Finally, there is strong evidence that most causal linkages are confirmed during normal market conditions. Policy recommendations are subsequently derived.

Surface runoff and soil losses in the case of potato cultivation using de-stoning technology on gentle slopes (Haplic Cambisol) were studied in 2020–2022. Different ridges shapes were compared: control (smooth shaped ridges), pits, pits plus loosening, pits plus loosening plus cover crop (Triticum aestivum L.) sowing in trail furrows. Runoff and soil losses were studied approximately 1 and 2 months after planting potatoes. The obtained results showed the highest reduction of surface runoff and soil losses in the treatment with cover crop sowing. In this variant, soil losses were reduced by 65–81% (1 month after planting) and 54–85% (2 months after planting) in case of simulated rainfall on the soil with natural moisture (or these losses were reduced by 51–93% and 50–76% in case of 15-min rainfall). On average, tuber yields reached 29.4 t/ha (pits + loosening) to 30.6 t/ha (pits) in 2020–2022. The different abilities of the tested shapes of ridges and furrows to retain water did not significantly affect the achieved yields of tubers, as rainfall was not a limiting factor in the monitored period. The yield differences among all tested treatments reached units of tons per hectare if the entire dose of nitrogen was applied at planting. Splitting the total nitrogen dose (50% at planting, 50% at loosening) gave significantly (P < 0.05) higher yields (34.2 t/ha) than a single application at planting. The treatment pits plus loosening with fertilisation provided a 19–26% higher tuber yield than pits plus loosening with a total N dose applied at planting.

The presented study estimated the aboveground biomass (AGB) of Pinus roxburghii (chir pine) natural forests and plantations, and created biomass maps using a relationship (regression model) between AGB and Sentinel-2 spectral indices. The mean AGB and BGB (belowground biomass) of natural forests were 79.54 Mg·ha^–1 and 20.68 Mg·ha^–1, respectively, whereas the mean AGB and BGB of plantations were 94.48 Mg·ha^–1 and 24.56 Mg·ha^–1, respectively. Correlation showed that mean diameter at breast height (DBH) and mean height have weak relationships with AGB, and BGB has shown correlation coefficients (R² = 0.46) and (R² = 0.56) for polynomial models. Regression models between AGB (Mg·ha^–1) of Pinus roxburghii natural forest and Sentinel-2 spectral indices showed a strong relationship with Ratio Vegetation Index (RVI) with R² = 0.72 followed by Normalized Difference Vegetation Index (NDVI) and Atmospherically Resistant Vegetation Index (ARVI) with R² = 0.70. In contrast, the lower performance of spectral indices has been shown in regression with plantation AGB. Correlation coefficients (R²) were 0.41, 0.41, and 0.40 for RVI, NDVI, and ARVI, respectively. All indices showed that the distribution of AGB data was not the best fit with the linear regression model. Therefore, non-linear exponential and power models were considered the best fit for NDVI, RVI, and ARVI. A biomass map was developed from RVI for both natural forests and plantation because RVI has the highest R² and lowest P-value.

The effect of drought stress on carbon metabolism in the leaves and roots of bermudagrass was investigated. Plants established in PVC tubes suffered from three water treatments for 10 days. C138 and Tifway (drought-tolerant) were found to have lower relative electrical conductivity and higher water use efficiency than C32 (drought-sensitive) under moderate drought by increasing carotenoid and soluble sugar content and rapidly decreasing leaf starch content. The sucrose synthase activity of leaves and roots, acid invertase and neutral invertase activity of C32 roots substantially decreased under severe drought, resulting in a slow sucrose decomposition rate and significantly lower fructose and glucose contents than C138 and Tifway. The activities of four carbon metabolism enzymes and sucrose content in the leaves were greater than those in the roots, while the fructose and glucose contents were on the contrary, indicating that bermudagrass transported fructose and glucose obtained from sucrose decomposition from leaves to roots under drought to reduce roots damage. The path analysis indicated that leaves neutral invertase activity, and roots soluble sugar content might be the key parameter of carbon metabolism in bermudagrass under drought.

Optimising diagnostic methods in shelters so that they are as economical as possible for the shelter is especially important because shelters often have a significant lack of funds and so usually do not carry out preventive screening of cats. Dermatophyte fungi spread quickly and can infect shelter staff. The aim of our work was to identify the occurrence of Microsporum canis in shelter cats. It aimed to determine the prevalence of M. canis in cats at the selected shelter and compare the efficiency of detection using a Wood’s lamp and culturing on Sabouraud’s agar. All cats present in the shelter at the time of the study (n = 70) were examined with Wood’s lamp and hair sampling followed by subsequent culturing on Sabouraud’s agar. Identification of fungi was based on microscopic proof of macroconidia and microconidia. The prevalence of M. canis by diagnosis on Sabouraud’s agar was 64.29% of cats, with the help of Wood’s lamp 48.57% of cats showed positive fluorescence. The sensitivity of the Wood lamp examination was 71% and the specificity was 92%. Our study suggests that Wood’s lamp could be used by trained shelter personnel for the first examination of cats at reception and could significantly reduce the risk of spreading M. canis in shelters.

Industrial air pollution, particularly cement dust, affects the leaf water status and resource utilisation and finally decreases primary production. Evaluating the relative water content (RWC), leaf mass per unit area (LMA), specific leaf area (SLA), and leaf water per unit area (LWA) helps selecting more tolerant species for dusty polluted areas. In this study, we compare two species of Quercus castaneifolia C.A.Mey and Carpinus betulus L. in a polluted site (PL) around a cement factory, and a unpolluted site (UPL) in Mazandaran province, Northern Iran. Ten individual trees of each species were tagged at each site, and twenty fully developed leaves were collected for further analysis and calculation. Based on the results, RWC and LWA were significantly lower in the PL site (61.0% and 0.0075 g·cm^–2, respectively) compared to the UPL site (71.1% and 0.0114 g·cm^–2, respectively) for Q. castaneifolia. However, no significant differences were observed in selected variables between PL and UPL sites for C. betulus. Among the studied variables, SLA was significantly higher in C. betulus (259.1 cm²·g^–1) compared to Q. castaneifolia (189.8 cm²·g^–1). Our results indicated that C. betulus responds better to dust pollution in terms of leaf water variables.

Plantain is the most important crop for the Peruvian Amazonian population, developed in recent alluvial soils rich in nutrients, but fragile and susceptible to degradation. Therefore, the impact of permanent cultivation was evaluated, through modelling, on indicators of recent alluvial soil quality and production in plantations of Musa paradisiaca L. var. Harton, in the Aguaytia River valley, Peru. The treatments were areas with permanent plantain plantations of 2 (T0), 15 (T1), 4 (T2), and 5 (T3) years of management, evaluating soil physicochemical indicators and plantain production indicators. The results show significant differences for all yield and soil indicators evaluated, except for bulk density (Bd), clay fraction, soil organic matter (OM) and N. The modelling determined a significant positive impact on Bd and a significant negative impact on pH, P, pseudostem diameter and height, commercial fingers and bunch weight. In conclusion, the modelling shows trends of quality and yield reduction in 15 years of permanent management of plantain Var. Harton, and compromises the sustainability of the agroecosystem in the medium term.

Steinernema glaseri is a potential biocontrol agent against white grubs of the Phyllophaga spp. complex; however, its suitability for in vitro multiplication has been scarcely investigated. In this study, the effects of the surface culture of NJ-43 strain with its symbiotic bacteria Xenorhabdus poinarii on egg-yolk agar (P2), chicken-liver agar and nutrient meat-peptone (MP) agar on infective juvenile (IJ) productivity and their virulence against Galleria mellonella larvae were investigated. The bacteria on the surface of the agar were first incubated in darkness at 30 °C for 54–102 h, and then 100 surface-sterilised IJs were added. After two harvests, the accumulated productivity was higher on chicken-liver agar (536 × 103 IJs/m2 day) and P2 agar (534 × 103 IJs/m2 day) than on nutrient MP agar (58 × 103 IJs/m2 day). The mean virulence of the in vitro produced IJs was 46–60% and showed no statistically significant difference among the three culture media. In conclusion, the maximum multiplication factor of S. glaseri NJ-43 on solid media was 385, and its original virulence was retained.

This research paper addresses the hypothesis that the peptidoglycan recognition protein 1 (PGLYRP1) gene polymorphism (Tyr76His; dbSNP ID: ss104796364) has an influence on some performance traits and causes of culling in Polish Holstein-Friesian red-white cows. The study involved 134 cows kept on a farm in the south-west of Poland. PGLYRP1 genotypes TT, CT, and CC were detected. It was shown that compared with cows with genotypes CT and TT, the individuals with genotype CC were characterised by higher lifetime yields and higher amounts of lactation milk, fat, and protein. A beneficial effect of genotype CC, compared with genotype TT, was also noted in the case of the lifespan and, consequently, the length of the productive life and the average number of lactations. Diseases of the musculoskeletal system (genotypes CC and TT) and disorders of the reproductive system (genotype CT) were the most common causes of culling. An essential practical observation was the potentially higher susceptibility of cows with genotype CC to mastitis, which resulted in the necessity to cull over one-fifth of the animals in this group. Simultaneously, no cows in this group were culled due to low performance or metabolic, gastrointestinal, and respiratory diseases. Therefore, the PGLYRP1 gene seems to be a promising potential herd health marker; however, to consider it the main gene, it is necessary to extend the investigations to include more individuals and other breeds of dairy cattle.

Heat resistance of bacteria is a factor potentially limiting the production of safety foods. We focused on five Enterobacteriaceae strains related to cheese stretching and sub-pasteurisation experimental temperatures of 50–59 °C. Heat resistance was screened and obtained data were fitted to a classical log-linear model with D-values indicating highly heat-resistant strains used. For example in Klebsiella oxytoca S525, D(50)-value was 96.1 min and D(59)-value 5.1 min. In subsequent detailed measurements, the shape of inactivation curves was sigmoid with defined lag, log-linear and stationary phase. We suggest calculating refined D-values (D^r-values) using only data obtained in log-linear phases, namely D^r(temperature; lag phase). In K. oxytoca S525, the obtained results were: D^r(50; 80.9) = 61.7 min, D^r(53; 12.4) = 36.8 min, D^r(56; < 10) = 10.6 min, and D^r(59; < 3) = 4.3 min. The research of particular inactivation phases can provide interesting findings both in science and industrial practice, especially concerning the passage or persistence of hazardous strains in food processing plants.

The APETALA 2/ethylene response factors (AP2/ERFs) are considered essential in plant disease resistance responses. In this study, a novel eggplant AP2/ERF transcription factor gene, StPti5, was identified and functionally described from wild eggplant (Solanum torvum Sw.). The results of bioinformatics analysis show that StPti5 protein contains a DNA-binding AP2/ERF domain and shares high degree of amino acid similarity with the other known AP2/ERF domain. Subcellular localization assay shows that StPti5 protein was localized in the nucleus. Expression of StPti5 was induced by infection with Verticillium dahliae, ethylene, and methyl jasmonate. Analysis of expression patterns suggests that the function of StPti5 in resistance to Verticillium wilt was most closely linked to ethylene signaling. Overexpression of StPti5 in Arabidopsis thaliana could improve disease resistance to V. dahliae and activate genes linked to the ethylene signaling pathway. Studies on the A. thaliana defence response revealed that the formation of reactive oxygen species (ROS) increased considerably following overexpression of StPti5. In summary, our analysis suggest that StPti5 gene is a functional gene that could improve eggplant's resistance to V. dahliae.

Hyperspectral imaging technology has emerged as a prominent research area for quantitatively estimating soil nutrient content owing to its non-destructive, rapid, and convenient features. Our work collected the data from soil samples using the hyperspectrometer. Then, the data were processed. The competitive adaptive reweighted sampling (CARS) algorithm reduced the original 148 bands to 13, which accounted for 8.8% of the total bands. These selected bands possess a certain level of interpretability. Based on the modelling results, it can be concluded that the prediction model constructed by the least squares support vector machine (LSSVM) exhibited the highest accuracy. The coefficient determination, root mean square error, and ratio performance deviation were 0.8295, 2.95, and 2.42, respectively. These findings can provide theoretical support for the application of hyperspectral technology in detecting the content of the AHN in soil. Moreover, they can also serve as a reference for the rapid detection of other soil components.

The aim of this study was to determine the effect of a granular poultry manure fertiliser on the yield and the quality of white cabbage (Brassica oleracea var. capitata), and to determine the effect on the soil agrochemical properties. The effect of the granular poultry manure fertiliser and mineral fertiliser (applied separately and combined at different times – in early spring and in autumn) on the cabbage yields was determined. Investigations were carried out in the fields of the Institute of Horticulture, the Lithuanian Research Centre for Agriculture and Forestry. The object of the research – white cabbage ‘Socrates’ H. The highest white cabbage marketable yield (80.5 t/ha) and the highest amount of vitamin C (7.80 mg per 100 g of products) was obtained by applying the granular poultry manure fertiliser in the autumn and the mineral fertiliser in the spring, where the granular poultry manure fertiliser applied in the early spring and the granular poultry manure fertiliser applied in the autumn with the mineral fertiliser applied in spring retained a higher content of humus (1.82–1.94%), organic carbon (1.06–1.12%) and total nitrogen (0.099–0.147%). The mineral nitrogen residue in the soil decreased when the cabbage was fertilised in the spring with the mineral fertiliser and when fertilised in the spring with the mineral fertiliser in combination with the granular poultry manure fertiliser by 8.1–10.8 kg/ha. The minimum content of nitrates in the heads of the white cabbage was found after using the granular poultry manure fertiliser in the autumn.

The case study aims to describe the nephrotic syndrome (NS) in a castrated 3-year-old male Cocker Spaniel dog. The patient arrived at the hospital with a loss of appetite and weakness. Skin oedema with ascites was observed along with hypoalbuminaemia, hypoproteinaemia, hyperlipidaemia, hypercholesterolaemia, and proteinuria (urine protein to creatinine ratio = 22.4). Based on these findings, the patient was diagnosed with NS, although a renal biopsy was not conducted. Prednisolone (1 mg/kg, p.o. q12 h) and mycophenolate mofetil (10 mg/kg, p.o. q12 h) were prescribed as the immunosuppressive drugs, and previously cryopreserved allogeneic adipose tissue-derived mesenchymal stem cells (2 × 10⁷ cells/kg) were injected intravenously. After several weeks of treatment, the patient recovered from NS. This is the first case report on immunosuppressive drugs and allogeneic mesenchymal stem cells being used to treat a dog with NS.

The aim of this study was to validate selected precision livestock farming (PLF) methods of nutrition and feeding management of high-yielding Holstein dairy cows. In a feeding trial with 36 dairy cows, the effect of replacing 0.1 kg of sodium bicarbonate in the control total mixed ration (TMR-C) with 1 kg of wheat straw in the experimental total mixed ration (TMR-S) on the physiological status of cows and the amount of milk produced (milk yield, MY) was investigated. Feed intake time (FT), as measured using tensometric feed troughs (TFT), was significantly longer with TMR-S (188 min) than with TMR-C (157 min). Differences between TMR-C and TMR-S were not significant for FT or rumination time (RT), as measured by a sensor in the collar (VSC). There was only a weak correlation between the two technologies (TFT vs. VSC) for FT (r = 0.27). Differences between TMR-C and TMR-S were not significant for values measured in rumen fluid (pH, acid and ammonia levels) nor for values measured by sensors in the milking parlour (MY, fat and protein percentage of milk). Milk analysis in the laboratory showed that the cows fed TMR-C had higher urea (26.6 vs. 22.7 mg/100 ml) and free fatty acid (0.87 vs. 0.33 mmol/100 g) levels in milk. Moderate correlations were between TMR intake and MY (r = 0.55); between MY and milk fat (r = –0.46); between milk fat and milk protein (r = 0.63); and between milk fat and milk protein measured by sensors and in the laboratory (r = 0.47 and r = 0.42, respectively). In view of the above results, further research and data validation for each technology are needed.

Nutraceuticals are food ingredients that provide extra health advantages that expand above their nutritional value. Nutraceuticals comprise amino acids, antioxidants, minerals, vitamins, probiotics, prebiotics, synbiotics, enzymes, organic acids, fatty acids, medicinal plants, etc. Recently, nutraceuticals have acquired much attention in poultry industry by reason of their potential effects on establishing the normal physiological status, supporting the immune system, and disease prevention, which consequently enhances productivity. The technique of in ovo feeding (IOF) of nutraceuticals holds several promises in poultry industry. The vital benefits of IOF of nutraceuticals are enhancement of intestinal development, establishment of a balanced microbial population in the gut, support of intestinal physiology and health. Interestingly, IOF of nutraceuticals participates in improving the antioxidative properties and energizing the immune system, which thereby translated into greater performance and bigger resistance to diseases, especially in early life challenges. The current review attempts to throw more light on the fresh results associated with the profits of IOF of nutraceuticals on intestinal histomorphology, intestinal microbiota, antioxidative properties, immune responsiveness, hatchability, chick quality, and growth performance in poultry.

Optimum irrigation scheduling and new technologies are the key to the successful practice of modern agriculture and natural resources, such as water management. Α three-year research project was conducted at Velestino, Magnesia, Greece. The aim was to study whether vegetation indices can be used to estimate the crop coefficients of corn in order to apply an intelligent method of irrigation using drones in the future. The normalised difference vegetation index (NDVI), the soil-adjusted vegetation index (SAVI), the renormalised difference vegetation index (RDVI) and a new index [difference infrared – green vegetation index (DIGVI)] were calculated using multispectral photos from a camera adapted to a drone. Three different methods were applied to calculate the crop coefficients: (i) the water balance and the FAO Penman-Monteith reference evapotranspiration, (ii) the climatic data, (iii) the vegetation indices. The irrigation dose covered 100% of the crop water needs according to the soil moisture measurements and the single crop coefficient values. The statistical analysis and the simple linear regression method showed that the corn crop coefficients can be estimated when these indices are used as independent variables.

20α-hydroxysteroid dehydrogenase (20α-HSD) is a member of the aldo-keto reductase family. These enzymes play a pivotal role in regulating steroid hormones, such as androgens, oestrogen, and progesterone, and are, therefore, considered vital targets for determining whether a pregnancy is maintained. In this study, we investigated the association between 20α-HSD and apoptosis-related genes in luteal tissues (at 30, 60, and 90 days of gestation) and cells from early gestation in cattle. The corpus luteum altered the number of large lutein cells from 30–90 days. The change in the junction of the connective tissue appeared to affect the density of the corpus luteum. In addition, 20α-HSD was detected in the corpus luteum and cultured cells during early pregnancy, in contrast to the results of previous studies. The overall expression pattern of the 20α-HSD and Casp-3 proteins was lower on day 50 of gestation than on days 30 and 90. However, the 20α-HSD expression gradually increased from 30 to 90 days of gestation. When the 20α-HSD protein was increased to 0.5 μg/ml, 1 μg/ml, and 1.5 μg/ml in the luteal cells collected on day 30 of pregnancy, apoptosis was analysed after 48 hours. 20α-HSD generated in the cells was confirmed, and the concentration gradually decreased as the concentration increased. However, the expression of Casp-3 showed an overall similar expression pattern. Notably, the 20α-HSD and Casp-3 proteins were lowest at 1.5 μg/ml supplemented with 20α-HSD, with higher levels in the cytosol than in the cytoplasm. These results suggest that 20α-HSD plays a role in maintaining normal pregnancy, particularly by regulating the progesterone concentrations during luteal cell development.

The present study aimed to apply a multi-residue method for the screening and quantification of pesticide residues in ciders, low alcoholic beverages made by fermentation of apple juice. Twenty bottled craft cider samples purchased from the Czech market were analysed for pesticide residues. The residues of pesticides were extracted from samples using the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) procedure in combination with additional solid-phase extraction (SPE) sample clean-up to achieve the lowest detection limit possible. In this study, targeted screening of pesticide residues in the samples was performed with the Q-Orbitrap mass spectrometry instrument. We identified 18 pesticides in cider samples analysed by screening method using an accurate-mass database of about 500 pesticide compounds, including their retention times, empirical formulas, and characteristic fragments. Additionally, liquid chromatography with high-resolution tandem mass spectrometer (LC-HRMS/MS) was used for re-analysis of positive findings of pesticides in samples and allowed to quantify compounds of interest at 0.2 µg L^–1 concentration level. The monitoring scheme was applied to the set of craft ciders, and the results revealed the presence of pesticide residues in most of the samples at trace levels ranging from 0.5 to 5 µg L^–1 and rarely at a level higher than 10 µg L^–1.

The present study was conducted to explore the variability generated through recombination breeding for nine economically important traits in Indian mustard (Brassica juncea L. Czern & Coss.). Delineation of the inbred lines to different gene pools, based on genetic diversity, enables their utilisation in hybrid breeding. The unweighted pair group method with arithmetic mean (UPGMA) and a Euclidean distance matrix was used to delineate the inbred lines to clusters. The variability was studied using the range and coefficients of variation of the traits. Significant variability was observed for all studied traits except for oil content and days to maturity. 128 Indian mustard genotypes were grouped into four distinct gene pools based on genetic diversity. A set of 20 most diverse genotype combinations was produced. Promising inbred lines were identified and recommended as donors for the respective trait. The pedigree analysis of the inbred line groups revealed, that recombination breeding caused a large diversity as confirmed by the assignment of inbred lines with the same parentage to specific clusters.
