The forage maturation hypothesis (FMH) states that energy intake for ungulates is maximised when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource selection should vary across ungulate species. By combining GPS relocations with remotely sensed data on forage characteristics and surface water, we quantified the effect of body size and digestive system in determining movements of 30 populations of hindgut fermenters (equids) and ruminants across biomes. Selection for intermediate forage biomass was negatively related to body size, regardless of digestive system. Selection for proximity to surface water was stronger for equids relative to ruminants, regardless of body size. To be more generalisable, we suggest that the FMH explicitly incorporate contingencies in body size and digestive system, with small-bodied ruminants selecting more strongly for potential energy intake, and hindgut fermenters selecting more strongly for surface water.

Disordered eating behaviors and depressive symptoms can be problematic during pregnancy for both the individual and their offspring. Our study aimed to determine the extent to which body image dissatisfaction early in pregnancy predicts eating disorder behaviors and/or depressive symptoms across pregnancy. Participants ( = 253) completed self-report assessments of depressive and eating disorder symptoms alongside the modified Body Image in Pregnancy Scale in their first, second, and third trimesters.

Introduction: Breast cancer is the most common malignancy among women and the second leading cause of cancer-related deaths worldwide. Resveratrol, a polyphenolic stilbene derivative found in grapes, red wine, and other plants, possesses anti-cancer properties. Various studies have reported the potential of different nanomaterials to act as radiosensitizers against tumor cells.

Aim: Our aim was to ascertain whether metformin can reduce insulin requirement without compromising glycaemic control during pregnancy in women with type 1 diabetes.
Methods: A total of 126 pregnant women with type 1 diabetes were recruited for a randomised, double-blind, placebo-controlled multicentre study. The primary outcome was total insulin change, defined as the difference between baseline and third trimester maximum insulin dose (IU).

Silicon dioxide nanoparticles (SiO NPs) are a novel material with a wide range of applications whose cumulative effects in the body pose certain health risks. The types of gastric injuries caused by different-sized SiO NPs and their mechanisms, however, remain unclear. Based on this, we established a mouse subchronic exposure model (10 mg/kg/d, 21 consecutive days of tube-feeding) with different SiO NP sizes (50, 300, and 1000 nm) in conjunction with in vitro MC9 and BMMCs models (160 μg/mL exposure for 24 h) to explore the gastric injury mechanisms.

Background And Purpose: Socioeconomic determinants of health impact childhood development and adult health outcomes. One key aspect is the physical environment and neighborhood where children live and grow. Emerging evidence suggests that neighborhood deprivation, often measured by the Area Deprivation Index (ADI), may influence neurodevelopment, but longitudinal and multimodal neuroimaging analyses remain limited.
