Distribution of body fat is associated with physical performance of male amateur triathlon athletes.

Publication Type:Academic Journal

Source(s):The Journal of sports medicine and physical fitness [J Sports Med Phys Fitness] 2022 Feb; Vol. 62 (2), pp. 215-221. Date of Electronic Publication: 2021 Mar 05.

Abstract:Background: Endurance sports are strongly associated with maximum oxygen uptake, anaerobic threshold, running economy and body fat percentage. Despite the importance for performance of the low-fat mass being a consensus in the literature, there are no ...

Mitochondrial Redox Signaling in O 2 -Sensing Chemoreceptor Cells.

Publication Type:Academic Journal

Source(s):Antioxidants & redox signaling [Antioxid Redox Signal] 2022 Aug; Vol. 37 (4-6), pp. 274-289. Date of Electronic Publication: 2022 Apr 18.

Abstract:Significance: Acute responses to hypoxia are essential for the survival of mammals. The carotid body (CB), the main arterial chemoreceptor, contains glomus cells with oxygen (O 2 )-sensitive K + channels, which are inhibited during hypoxia to ...

Impact of warming on aquatic body sizes explained by metabolic scaling from microbes to macrofauna.

Publication Type:Academic Journal

Source(s):Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2022 Jul 12; Vol. 119 (28), pp. e2201345119. Date of Electronic Publication: 2022 Jul 05.

Abstract:Rising temperatures are associated with reduced body size in many marine species, but the biological cause and generality of the phenomenon is debated. We derive a predictive model for body size responses to temperature and oxygen (O 2 ) changes based ...

Identifying critical DO 2 with compensatory reserve during simulated hemorrhage in humans.

Publication Type:Academic Journal

Source(s):Transfusion [Transfusion] 2022 Aug; Vol. 62 Suppl 1, pp. S122-S129. Date of Electronic Publication: 2022 Jun 22.

Abstract:Background: Based on previous experiments in nonhuman primates, we hypothesized that DO 2 crit in humans is 5-6 ml O 2 ·kg -1  min -1 .Study Design and Methods: We measured the compensatory reserve (CRM) and calculated oxygen delivery (DO 2 ) in 166 he...

Nardilysin in adipocytes regulates UCP1 expression and body temperature homeostasis.

Publication Type:Academic Journal

Source(s):Scientific reports [Sci Rep] 2022 Mar 02; Vol. 12 (1), pp. 3449. Date of Electronic Publication: 2022 Mar 02.

Abstract:Brown adipose tissue (BAT) dissipates chemical energy as heat through uncoupling protein 1 (UCP1). The induction of mitochondrial reactive oxygen species (ROS) in BAT was recently identified as a mechanism that supports UCP1-dependent thermogenesis. We...

Real-world estimate of the value of one metabolic equivalent in a population of patients planning major surgery.

Publication Type:Academic Journal

Source(s):Internal medicine journal [Intern Med J] 2022 Aug; Vol. 52 (8), pp. 1409-1414. Date of Electronic Publication: 2022 May 31.

Abstract:Background: One metabolic equivalent (MET) is equal to resting oxygen consumption. The average value for one MET in humans is widely quoted as 3.5 mL/kg/min. However, this value was derived from a single male participant at the end of the 19th century ...

Thermoneutral Environment for Neonates: Back to the Basics.

Publication Type:Academic Journal

Source(s):Neonatal network : NN [Neonatal Netw] 2022 Aug 01; Vol. 41 (5), pp. 289-296.

Abstract:Thermoregulation is an essential component to the stability and long-term outcomes of newborns and critically-ill neonates. A thermoneutral environment (TNE) is an environment in which a neonate maintains a normal body temperature while minimizing ener...

Mitochondrial acute oxygen sensing and signaling.

Publication Type:Academic Journal

Source(s):Critical reviews in biochemistry and molecular biology [Crit Rev Biochem Mol Biol] 2022 Apr; Vol. 57 (2), pp. 205-225. Date of Electronic Publication: 2021 Dec 01.

Abstract:Oxygen (O 2 ) is essential for life and therefore the supply of sufficient O 2 to the tissues is a major physiological challenge. In mammals, a deficit of O 2 (hypoxia) triggers rapid cardiorespiratory reflexes (e.g. hyperventilation and increased hear...
