Summary: The study developed a yeast extract capable of inhibiting melanoma cells using ultrasound technology, showing that it effectively reduces cell growth and proliferation, as well as tumor volume in mice. Optimal extraction conditions resulted in increased total extraction and 8-glucan yields, suggesting that UAEY may represent an effective anti-skin cancer agent.

Summary: This study aimed to examine the agreement between BMI-based nutritional status and perceived nutritional status and explore the association between weight perception accuracy and weight control practices in the Chilean adult population. The results showed fair agreement between BMI-based and perceived nutritional status in the total sample, with higher accuracy in women, younger respondents, and those with higher education and income. Individuals with overweight or obesity tended to underestimate their nutritional status. Weight loss behaviors were more related to perceived nutritional status rather than BMI-based status in all groups.

Summary: Beta-glucan, a polysaccharide found in the cell wall of yeast, has immunostimulatory properties. Although spores of yeast also contain beta-glucan, they have been poorly studied as application tools. However, by genetic manipulation, spores can be modified to expose the beta-glucan layer on the cell surface. These modified spores are phagocytosed by mammalian cells in a manner dependent on the receptor dectin-1, and they induce higher levels of proinflammatory cytokines compared to vegetative cells.

Summary: This meta-analysis study found that probiotic supplementation can significantly reduce BMI, waist circumference, and hip circumference in overweight and obese patients, but the effect on body weight is not significant. Although there is a positive trend, further research is needed before recommending probiotics as a therapeutic strategy for these patients.

Summary: This study evaluated the effects of concentrated brewer's yeast on gut health in dogs. The results showed that dogs receiving the yeast had reduced gut permeability and reduced markers of inflammation, suggesting a positive effect of yeast on gut health in healthy dogs.

Summary: This article briefly reviews the intellectual history of energy homeostasis, with a focus on food intake and energy storage. It discusses the development of physiological energetics by Lavoisier and the concept of homeostasis by Bernard and Cannon. The article also introduces the control-theory model in understanding body-weight regulation.

Summary: The problem of overweight and obesity is increasing in the population and is associated with metabolic disorders and increased risk of death. This study assessed the changes in body composition and physical fitness in children participating in a weight-loss program and found a possible relationship between changes in body composition and improvements in fitness. Both BIA and DXA methods were equally useful for measuring body composition.

Summary: In this study, a rapid cell rupture method using glass beads was selected for the lysis of spent brewer's yeast to obtain beta-glucans. The optimal parameters for cell lysis were found to be a cell suspension concentration of 5%, a ratio of yeast/glass beads of 1:2, and a vortexing cycle of 3, with a disruption efficiency of 99.8%. The beta-glucan fraction extracted from the optimal sample showed a high content of beta-glucan.

Summary: This study found that high body weight variability (BWV) is associated with an increased risk of depression. Even after adjusting for other factors, the association between high BWV and depression remains. This suggests that BWV may be an important risk factor for depression.

Summary: The aim of this study is to determine the effects of yeast vacuoles on triglyceride accumulation and differentiation of pre-adipocytes to adipocytes using 3T3-L1 cells. After treatment with vacuoles, lipid droplets and triglyceride accumulation were reduced, and expression levels of C/EBP alpha and PPAR gamma in vacuole-treated adipocytes were significantly reduced. Yeast-derived vacuoles could be an important source for inhibiting lipid accumulation and obesity-related inflammation by suppressing adipogenesis.

Summary: This study aimed to investigate the effects of Saccharomyces cerevisiae-fermented rice (FR) and β-glucan on the growth performance, carcass characteristics, immune response, and fatty acid profiles of turkey broilers. The results showed that supplementation of 4% β-glucan and 4% FR significantly improved the growth performance and immunity of turkey broilers, without significant effects on carcass characteristics and blood profiles.

Summary: This study reveals the structures and mechanisms of yeast FKS1 and the echinocandin-resistant mutant FKS1(S643P) using cryo-electron microscopy, advancing the understanding of fungal β-1,3-glucan biosynthesis and providing insights into drug-resistant mutations of FKS1. It establishes a foundation for the development of new antifungal drugs by targeting FKS.
