Cavefish cope with environmental hypoxia by developing more erythrocytes and overexpression of hypoxia-inducible genes [PDF]

eLife, 2019
Dark caves lacking primary productivity can expose subterranean animals to hypoxia. We used the surface-dwelling (surface fish) and cave-dwelling (cavefish) morphs of Astyanax mexicanus as a model for understanding the mechanisms of hypoxia tolerance in the cave environment. Primitive hematopoiesis, which is restricted to the posterior lateral mesoderm

Hypoxia as an Environmental Cause of Holoprosencephaly

The FASEB Journal, 2009
Holoprosencephaly is a complex congenital malformation of the forebrain and face. Recent clinical evidence shows a correlation between hypoxia and holoprosencephaly. We examined the role of hypoxia in causing holoprosencephaly in chick embryos. Chicken eggs were incubated in 13% O2 (hypoxia) or in 20% O2 (normoxic control).

Organism-sediment interactions govern post-hypoxia recovery of ecosystem functioning [PDF]

, 2012
Hypoxia represents one of the major causes of biodiversity and ecosystem functioning loss for coastal waters. Since eutrophication-induced hypoxic events are becoming increasingly frequent and intense, understanding the response of ecosystems to hypoxia ...

Appetite and gut hormone responses to moderate-intensity continuous exercise versus high-intensity interval exercise, in normoxic and hypoxic conditions. [PDF]

, 2015
This study investigated the effects of continuous moderate-intensity exercise (MIE) and high-intensity interval exercise (HIIE) in combination with short exposure to hypoxia on appetite and plasma concentrations of acylated ghrelin, peptide YY (PYY), and

Dietary supplementation of heat-treated Gracilaria and Ulva seaweeds enhanced acute hypoxia tolerance in gilthead sea bream (Sparus aurata) [PDF]

, 2017
Intensive aquaculture practices involve rearing fish at high densities. In these conditions, fish may be exposed to suboptimal dissolved O2 levels with an increased formation of reactive O2 species (ROS) in tissues.

Diverse of Erythropoiesis Responding to Hypoxia and Low Environmental Temperature in Vertebrates [PDF]

BioMed Research International, 2015
Erythrocytes are responsible for transporting oxygen to tissue and are essential for the survival of almost all vertebrate animals. Circulating erythrocyte counts are tightly regulated and respond to erythrocyte mass and oxygen tension. Since the discovery of erythropoietin, the erythropoietic responses to environment and tissue oxygen tension have ...

Physiological responses to hypoxia are constrained by environmental temperature in heterothermic tenrecs

Journal of Experimental Biology, 2023
ABSTRACTMalagasy tenrecs are placental hibernating mammals that seal the entrances to their burrows and hibernate either singly or in groups for 8–9 months, which is likely to create a hypoxic and hypercapnic burrow environment. Therefore, we hypothesized that tenrecs are tolerant to environmental hypoxia and hypercapnia.

Reducing the hypoxic fraction of a tumour model by growth in low glucose. [PDF]

, 1989
The question of whether growth under low glucose conditions leads to a reduced amount of cell hypoxia was investigated using an in vitro tumour analogue, the sandwich system.

Vasopressin and oxytocin release during prolonged environmental hypoxia in the rat [PDF]

Thorax, 1997
The mechanism causing peripheral oedema in hypoxaemic chronic obstructive pulmonary disease has not been established. Vasopressin, a powerful antidiuretic hormone involved in salt and water homeostasis, is released in response to acute hypoxia. However, the effect of prolonged hypoxaemia on hypothalamic and pituitary release of the magnocellular ...
