To compare the energy expenditure (EE) assessed by ventilator-derived carbon dioxide production (EE-VCO2-ventilator) and the energy expenditure calculated from six predictive equations with the gold standard energy expenditure measured with indirect calorimetry (IC) in mechanically ventilated patients.

Monocarboxylates, transported by monocarboxylate transporters (MCTs), have been proposed to influence energy homeostasis and exhibit altered metabolism during exercise. This study investigated the association between the Asp490Glu (T1470A) (rs1049434) polymorphism of the SLC16A1 (MCT1) gene and changes in body composition in males and females with overweight or obesity. The 173 participants (56.

To curb the obesity epidemic, it is imperative that we improve our understanding of the mechanisms controlling fat mass and body weight regulation. While great progress has been made in mapping the biological feedback forces opposing weight loss, the mechanisms countering weight gain remain less well defined. Here, we integrate a mouse model of intragastric overfeeding with a comprehensive evaluation of the regulatory aspects of energy balance, encompassing food intake, energy expenditure, and fecal energy excretion.

Plant chloroplasts store starch during the day, which acts as a source of carbohydrates and energy at night. Starch granule initiation relies on the elongation of malto-oligosaccharide primers. In Arabidopsis thaliana, PROTEIN TARGETING TO STARCH 2 (PTST2) and STARCH SYNTHASE 4 (SS4) are essential for the selective binding and elongation of malto-oligosaccharide primers, respectively, and very few granules are initiated in their absence.

Unraveling the metabolism of Treponema pallidum is a key component to understanding the pathogenesis of the human disease that it causes, syphilis. For decades, it was assumed that glucose was the sole carbon/energy source for this parasitic spirochete. But the lack of citric-acid-cycle enzymes suggested that alternative sources could be utilized, especially in microaerophilic host environments where glycolysis should not be robust.

Organisms allocate energetic resources between essential cellular processes to maintain homeostasis and, in turn, maximize fitness. The nutritional regulators of energy homeostasis have been studied in detail; however, how developmental signals might impinge on these pathways to govern metabolism is poorly understood. Here, we identify a non-canonical role for Hedgehog (Hh), a classic regulator of development, in maintaining intestinal lipid homeostasis in Caenorhabditis elegans.
