Acute physical exercise under hypoxia improves sleep, mood and reaction time
(Elsevier B. V., 2015-10-29)
This study aimed to assess the effect of two sessions of acute physical exercise at 50% VO2peak performed under hypoxia (equivalent to an altitude of 4500 m for 28 hours) on sleep, mood and reaction time. Forty healthy men ...
Hypoxia, hypoxia-inducible factor-1 alpha and vascular endothelial growth factor in a murine model of Schistosoma mansoni infection
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2010)
Gene expression promoted by the SV40 DNA targeting sequence and the hypoxia-responsive element under normoxia and hypoxia
(Associação Brasileira de Divulgação Científica, 2010-08-01)
The main objective of the present study was to find suitable DNA-targeting sequences (DTS) for the construction of plasmid vectors to be used to treat ischemic diseases. The well-known Simian virus 40 nuclear DTS (SV40-DTS) ...
Role of glycosylation in hypoxia-driven cell migration and invasion
(NLM (Medline), 2019)
Hypoxia, a common condition of the tumor microenvironment, induces changes in the proteome of cancer cells, mainly via HIF-1, a transcription factor conformed by a constitutively expressed β-subunit and an oxygen-regulated ...
Lidocaine reduces the hypoxia-induced release of an excitatory amino acid analog from rat striatal slices in superfusion
1. 1. Lidocaine has been extensively investigated as a potential neuroprotective drug against ischemiainduced neurodegeneration without reaching any satisfactory conclusion. 2. 2. The present work evaluates the effect of ...
The effects of acute hypoxia and hypercapnia on oxygen consumption of the freshwater European eel
When exposed to hypoxia, eels Anguilla anguilla were able to regulate and maintain VO2 down to a water oxygen tension (PWO2) of about 25 mmHg, a value far below those reported in other studies. When exposed to hypercapnia, ...
The effect of acute hypoxia on short-circuit current and epithelial resistivity in biopsies from human colon.
Background and Aims In isolated colonic mucosa, decreases in short-circuit current (ISC) and transepithelial resistivity (RTE) occur when hypoxia is either induced at both sides or only at the serosal side of the epithelium. ...
The dormancy-breaking stimuli "chilling, hypoxia and cyanamide exposure" up-regulate the expression of α-amylase genes in grapevine buds
It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
Hypoxia modulates phenotype, inflammatory response, and leishmanial infection of human dendritic cells
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Development of hypoxic areas occurs during infectious and inflammatory processes and dendritic cells (DCs) are involved in both innate and adaptive immunity in diseased tissues. Our group previously reported that macrophages ...
Ionotropic glutamatergic receptors in the rostral medullary raphe modulate hypoxia and hypercapnia-induced hyperpnea
(ELSEVIER SCIENCE BV, 2011)
It has been suggested that the medullary raphe (MR) plays a key role in the physiological responses to hypoxia and hypercapnia. We assessed the role of ionotropic glutamate receptors in the rostral MR (rMR) in the respiratory ...
