Forecasting vital genes involving Thirty-seven prokaryotes through merging information-theoretic characteristics.
The study concluded that biogenic MgO-NPs could be used to formulate a potent nanofertilizer for sustainable rice production in metal contaminated soils.Coastal sediments, where microplastics (MPs) accumulate, support benthic microalgae (BMA) that contribute to ecosystem functions such as primary production, nutrient recycling and sediment biostabilization. The potential interactions between MPs, BMA and associated properties and functions remain poorly understood. To examine these interactions, a survey of 22 intertidal sites was conducted. MP abundance, size and a suite of MP diversity indices (based on color and shape) were determined from surface sediments alongside biochemical and physical properties. MPs were detected at all sites and dominated by polypropylene (34%), polyester (18%) and polyethylene (11%). Fragment and fiber dominance (16-92% and 6-81% respectively) and color-shape category diversity varied significantly by site. Distance-based linear models demonstrated that estuary-wide, mean grain size and mud were the best predictors of MP abundance-diversity matrices, but variance explained was low (9%). Relationships were improved when the data was split into sandy and muddy habitats. In sandy habitats (8% mud), porewater ammonium was lower when fiber abundance and overall MP diversity were higher. The inclusion of porewater ammonium, organic matter content and pheophytins alongside physical properties explained a greater percentage of the variance in MP abundance-diversity for muddy habitats (21%). The results highlight the importance of examining plastic shapes and MP categories in addition to abundance and emphasize that functionally different habitats should be examined separately to increase our understanding of MP-biota-function relationships.The aim of the study was to develop marination liquids (MLs) enriched with probiotics (Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus rhamnosus or their combination) to improve the safety and sensory quality of meat during marination. The total acidity, total phenolic content, antioxidant and antimicrobial activities of MLs were in the range of 0.70-0.92 g tartaric acid/100 mL, 331.00-513.80 mg GAE/L, 71.10%-93.37% and 6.50-10.00 mm, respectively. At the end of the marination, the numbers of Escherichia coli O157 H7, Listeria monocytogenes and Salmonella Typhimurium on meat samples (≅6 log CFU/g) were decreased in the range of 0.7-2.7, 2.1-3.3 and 0.8-2.0 log CFU/g, respectively, depending on the type of ML and the treatment time used. Additionally, meat sample marinated with MLs containing L. casei was the most preferred sample in terms of appearance, color, flavor and general acceptability. These results showed that the existing effects of koruk juice were increased by probiotics.The objective of the study was to evaluate the effect of quantitative feed restriction on the carcass composition and physical, chemical, histochemical and sensory properties of meat from male and female nutria at the end of the feed restriction and fattening period. In the experiment, from two to eight months of age, males and females were divided into two groups one group was fed ad libitum throughout the experiment, and the second group was restricted to two weeks (from 11 to 12 weeks of age). The restricted nutrias received 75% ad libitum feeding. The significant interaction among feed restriction, sex and age was revealed only in the cross-sectional area of all muscle fiber types. Age was the main factor affecting carcass composition and meat quality characteristics. Sex-related differences in carcass composition and some sensory attributes and feed restriction-related differences in carcass composition were observed.Celastrol, a potent anticancer and anti-obesity drug, was first isolated from Tripterygium wilfordii Hook. f. and it is produced in small quantities in many members of the Celastraceae family. The heterologous reconstitution of celastrol biosynthesis could be a promising method for the efficient production of celastrol and natural and unnatural derivatives thereof, yet only part of the biosynthetic pathway is known. Here, we report a cytochrome P450 monooxygenase (TwCYP712K1) from T. wilfordii that performs the three-step oxidation of friedelin to polpunonic acid in the celastrol pathway. Catechin hydrate cell line Heterologous expression of TwCYP712K1 showed that TwCYP712K1 catalyses not only the transformation of friedelin to polpunonic acid but also the oxidation of β-amyrin or α-amyrin. The role of TwCYP712K1 in the biosynthesis of celastrol was further revealed via RNA interference. Some key residues of TwCYP712K1 were also screened by molecular docking and site-directed mutagenesis. Our results lay a solid foundation for further elucidating the biosynthesis of celastrol and related triterpenoids.
To gain insight into pregnant women's preferences if given a choice between getting antibiotic prophylaxis before or after cord clamping during caesarean delivery.

A qualitative semi-structured interview-study. The interviews were conducted at a Danish Hospital, with about 4000 deliveries a year. Fourteen individual semi-structured interviews were conducted with pregnant women, either considering or having a planned caesarean section, or scheduled for induction due to post-term gestational age. A systematic text condensation approach was used to analyze the transcribed interviews.

Ten of the fourteen women favored antibiotic administration after cord clamping. Despite any adverse effects to the infant's microbiota and increased risk of long-term health outcomes were only hypothetical and the risk reduction in postpartum infections being well documented, they did not want to expose their offspring to antibiotics. Those who preferred antibiotic prophylaxis before cord clamping were concerned, if they would be able to care for the infant in case of a maternal infection. Three of the women preferring antibiotics after cord clamping said they would potentially change preference, if the maternal risk was higher. Most women preferred to be informed of the use of prophylactic antibiotic and that the timing has consequences for trans-placental exposure to the infant.

With most of the interviewed women preferring antibiotic administration after cord clamping, we suggest patients should be involved in the decision regarding timing of prophylactic antibiotics before caesarean section.
