ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...

Abstract Background Obesity increases the risks and complexity of laparoscopic surgeries. Preoperative very low‐calorie diets (VLCDs) can demonstrate significant preoperative weight loss. However, the optimal VLCD duration remains unclear. Excessive loss of muscle mass associated with VLCDs may elevate surgical and postoperative risks. This study aimed

Physical Fitness Cut‐Points for Early Detection of Obesity Risk in Preschool Children
ABSTRACT Objective This study aimed to establish cut‐points for cardiorespiratory fitness, muscular strength, and speed‐agility and to evaluate their ability to detect general and central obesity risk in preschool children aged 3–5 years. Methods Briefly, 3179 Spanish preschoolers (52.8% boys) were evaluated.

Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Climatic conditions alter the phenology of species, which may threaten the synchrony of biotic interactions. However, how phenological synchrony across entire communities of plants and their pollinators responds to varying environmental conditions remains poorly understood.
