Summary: The study investigated the effects of activity-based anorexia (ABA) on whole body energy homeostasis in rats under different housing temperatures. Results showed that ABA rats exhibited hyperactivity and hypophagia, leading to weight loss and muscle cachexia. Increasing the housing temperature reversed these effects without impacting key hypothalamic pathways involved in energy metabolism.

Summary: Following a strict raw food diet may lead to undersupply of energy and essential nutrients. In this study, strict raw food eaters had lower body fat percentage and lower intake of certain nutrients compared to non-raw food eaters. They also had lower levels of HDL cholesterol, triglycerides, zinc, and vitamin D3.

Summary: Makorin RING finger protein 3 (MKRN3) is an important factor associated with Prader-Willi syndrome. It is expressed in the hypothalamus and mutations in the gene have been found in patients with central precocious puberty. The methylation status of the Mkrn3 promoter was investigated in female mice and differential methylation patterns were observed between pre-pubertal and pubertal/post-pubertal stages.

Summary: The flowering response of oilseed rape (OSR) to high ambient temperature is diverse, with one variety exhibiting opposite behavior. BnaFTA2 plays a key role in temperature-dependent flowering initiation in OSR, and additional molecular mechanisms are involved in its repression under high ambient temperature. The presence of H3K4me3 in BnaFTA2 is reduced at high temperature, suggesting a role for this active chromatin marker in the flowering response of OSR to warming.

Summary: Ambient electrospray can quickly convert preformed polydisperse nanoparticles into monodisperse particles, which then spontaneously self-assemble to form organized films within seconds. Uniform nanoparticles can be obtained without the need for additional chemicals or templates, and this method shows potential for creating advanced materials.

Summary: The study highlights the relationship between maternal and children nutritional status in India, showing that anaemic women are more likely to have anaemic children, and underweight mothers are more likely to have stunted, underweight, and wasted children. Targeting interventions towards anaemic women and children is crucial for achieving Sustainable Development Goals in the country.

Summary: In this study, the mutual relationship between the controlling nutritional status (CONUT) score and sarcopenia as prognostic factors in patients with advanced urothelial carcinoma (aUC) was comprehensively examined. The study found that the CONUT score and sarcopenia were significant and independent prognostic biomarkers and incorporating them into established prognostic models increased their predictive accuracy. These objective indices of a patient's general condition may assist in treatment decision-making for patients with aUC.

Summary: This study examines the impact of climate change on the nutritional status of young children in rural coastal Bangladesh. The findings indicate that temperatures exceeding 25 degrees Celsius have negative effects on children's nutritional status, while humidity has a positive impact. Exposure to changing climate during the fetal period also plays a significant role.

Summary: By studying freely behaving mice using calcium imaging, optogenetics, and chemogenetics, researchers found that two neuronal populations in the lateral hypothalamus guide hungry animals to make behavioral choices between nutritional and social rewards. One population of neurons increased food consumption by inhibiting hunger signals, while the other population limited feeding and drinking and promoted social interaction despite hunger or thirst. These findings shed light on the neuronal mechanisms of balancing competing needs and provide insights into the flexible fulfillment of essential needs in animals.

Summary: While UCP1 is essential for cold-induced thermogenesis, its presence alone does not protect mice from diet-induced obesity. A new mouse model with low UCP1 levels demonstrates that impaired cold-induced thermogenic capacity does not increase susceptibility to diet-induced obesity. Pharmacological activation of brown fat is necessary to promote negative energy balance in diet-induced obese mice.

Summary: This study evaluated the effectiveness of vaginal progesterone inserts therapy in cows with anestrus type II. The expression of progesterone and estrogen receptors in the endometrium was assessed, and blood levels of estradiol and progesterone were evaluated. The results showed a decrease in mRNA expression of certain receptors in both treated and untreated animals. However, treated animals showed an increase in the expression of specific receptors compared to untreated animals. In addition, the recurrence of ovarian cyclicity and pregnancy rates were higher in the treated group.

Summary: Embryo implantation is the most critical stage of pregnancy, dependent on the synchronized developmental capacity of the embryo and uterine receptivity. In early pregnancy, both the conceptus and uterus release various factors to facilitate successful implantation and placenta formation. MicroRNAs, which regulate gene expression, are considered important regulators of early pregnancy events.

Summary: The study identifies GPR183/EBI2 as the most highly expressed inhibitory G-protein-coupled receptor in brown adipose tissue, which decreases energy expenditure. Loss of Ebi2 in mice results in increased brown adipocyte energy expenditure in response to cold exposure, providing potential insights into modulating energy expenditure in humans.

Summary: The establishment of cell-to-cell communication is crucial for successful mammalian pregnancy. Extracellular vesicles (EVs) carrying unique molecular cargo have been identified as mediators of this communication during early pregnancy. However, the mechanism of EV-mediated crosstalk between early embryos and the endometrium needs further investigation. Understanding the role of EVs in mammalian reproduction can greatly enhance our knowledge of successful reproductive performance.

Summary: This study aimed to evaluate the alterations of WNT4 gene expression and protein immunoreactivity in endometrial cancer (EC) and their association with tumor characteristics, clinicopathological factors, and estrogen dependence. The results showed that WNT4 gene expression was decreased in EC samples, particularly in endometrioid EC, and was associated with tumor characteristics. However, there was no statistical difference in WNT4 protein immunoreactivity or estrogen receptor alpha immunoreactivity between EC and control group. The study also found that alterations in WNT4 gene expression tended to be mutually exclusive with alterations in ESR1 gene expression. Overall, this study highlights the importance of evaluating the molecular background of EC, and suggests that WNT4 gene may be a marker of functional estrogen signaling in endometrioid EC.
