The temperature variation of the maximum oxygen uptake and time to exhaustion in the spinning factory workers [PDF]

open access: yesطب کار, 2013
Background: Fatigue is an important inhibiting factor in human performance, so with rising aerobic power could be overcome individual fatigue. Based on the importance of maximum oxygen consumption at fatigue threshold, the purpose of this study was to ...

Characterization of oxygen uptake and mass transfer in flocculent yeast cell cultures with or without a flocculent additive [PDF]

open access: yes, 1996
The effect of solids concentration and the presence of the charged polymeric additive Magna Floc LT25 on gas-liquid oxygen transfer and oxygen consumption rates have been evaluated for flocculent yeast cells grown in batch fermentations.

Respiration Rates of Individual Bovine In Vivo-Produced Embryos Measured with a Novel, Scanning Electrochemical Microscopy

open access: yesJournal of Animal Reproduction and Biotechnology, 2014
Oxygen consumption is a useful parameter for evaluating mammalian embryo quality, since individual bovine embryos was noninvasively quantified by scanning electrochemical microscopy (SECM).

Age and Huddling as Determinants of Metabolic Rate in Grasshopper Mice (Onychomys leucogaster) [PDF]

open access: yes, 1979
The metabolic rates of grasshopper mice (Onychomys leucogaster) were determined every third day from birth to adulthood. Metabolic rates were quantitated by measuring oxygen consumption in an open circuit system.

Variable sediment oxygen uptake in response to dynamic forcing [PDF]

open access: yes, 2010
Seiche-induced turbulence and the vertical distribution of dissolved oxygen above and within the sediment were analyzed to evaluate the sediment oxygen uptake rate (JO2), diffusive boundary layer thickness (δDBL), and sediment oxic zone depth (zmax) in ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Prediction of VO\u3csub\u3e2\u3c/sub\u3e Peak Using Sub-Maximum Bench Step Test in Children [PDF]

open access: yes, 2011
The purpose of this study was to develop a valid prediction of maximal oxygen uptake from data collected during a submaximum bench stepping test among children ages 8-12 years.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

PON2 Deficiency Leads to Increased Susceptibility to Diet-Induced Obesity. [PDF]

open access: yes, 2019
(1) Background: Paraoxonase 2 (PON2) is a ubiquitously expressed protein localized to endoplasmic reticulum and mitochondria. Previous studies have shown that PON2 exhibits anti-oxidant and anti-inflammatory functions, and PON2-deficient (PON2-def) mice ...
