The family Nemesiidae is the second most diverse family of Mygalomorphae spiders. (Nemesiidae) is commonly found in hilly areas of central Argentina. These spiders are considered generalists due to their basal position in the phylogeny, but little is known about the trophic ecology of the species. Therefore, the objectives of this study were to study some of the species' predatory traits, such as feeding frequency and prey acceptance, and to assess its natural diet. In addition, two parameters - attack latency and consumption time - were measured for each accepted prey. We found that feeds every two days and accepts almost all prey offered. The most accepted prey items were beetle larvae and termites. In fact, termites were attacked faster than any other prey, suggesting they are a suitable prey for these spiders. In regard to the species' natural diet, we found remains of seven prey items, ants and beetles being the most frequent. In this study, we found that is polyphagous since it accepts different kinds of prey.

Unlabelled: While previous research has established correlations between pre-pregnancy body mass index (BMI), late-pregnancy blood glucose, and late-pregnancy blood lipid levels during pregnancy and offspring's physical development, the underlying mechanism of their interaction remains elusive. A birth cohort study was conducted on pregnant women, who are biologically female, delivering at a tertiary hospital in Wuhan City between May 2023 and April 2024, encompassing 1620 participants. We collected maternal socio-demographic data through questionnaires and obtained information on fasting blood glucose (FPG), lipid levels during the third trimester, and neonatal physical development from medical records.

Obesity, recognized as a metabolic disease and a global epidemic, calls for novel pharmacological interventions. Menthol, an organic compound, has shown promise in increasing energy expenditure and has been proposed as a potential anti-obesity drug. While preclinical studies have demonstrated menthol's preventive effect on body mass gain, none have investigated its efficacy in treating obesity.

This study aimed to evaluate the cholesterol-regulatory effects of lauric-acid-esterified octacosanol (LEO) and oleic-acid-esterified octacosanol (OEO) compared to their unmodified counterparts and to investigate the underlying mechanisms by partially substituting the fat content in obese C57BL/6J mice induced with a high-fat diet (HFD). Rice bran oil and coconut oil were also investigated as they are rich in oleic acid and lauric acid, respectively. The results showed that all supplemented groups significantly inhibited weight gain induced by the HFD, but the groups treated with esterified octacosanol exhibited a more pronounced effect.

Cataracts are significant causes of blindness, closely linked to prolonged hypercholesterolemia. While saffron has the potential for eye health, its effects on lens lesions remain understudied. This study aimed to investigate the effect of saffron on the lens changes in atherosclerotic-induced New Zealand white rabbits (NZWR).

Mycotoxin exposure from contaminated food is a significant global health issue, particularly among vulnerable children. Given limited data on mycotoxin exposure among Namibian children, this study investigated mycotoxin types and levels in foods, evaluated dietary mycotoxin exposure from processed cereal foods in children under age five from rural households in Oshana region, Namibia. Mycotoxins in cereal-based food samples (n = 162) (mahangu flour (n = 35), sorghum flour (n = 13), mahangu thin/thick porridge (n = 54), oshikundu (n = 56), and omungome (n = 4)) were determined by liquid chromatography-tandem mass spectrometry.
