Tumor Hypoxia Regulates Immune Escape/Invasion: Influence on Angiogenesis and Potential Impact of Hypoxic Biomarkers on Cancer Therapies

open access: yesFrontiers in Immunology, 2021
The environmental and metabolic pressures in the tumor microenvironment (TME) play a key role in molding tumor development by impacting the stromal and immune cell fractions, TME composition and activation.

Does individual variation in metabolic phenotype predict fish behaviour and performance? [PDF]

open access: yes, 2015
There is increasing interest in documenting and explaining the existence of marked intraspecific variation in metabolic rate in animals, with fishes providing some of the best-studied examples.

The Effect of Hypoxia and Hypoxia-Associated Pathways in the Regulation of Antitumor Response: Friends or Foes?

open access: yesFrontiers in Immunology, 2022
Hypoxia is an environmental stressor that is instigated by low oxygen availability. It fuels the progression of solid tumors by driving tumor plasticity, heterogeneity, stemness and genomic instability.

Effects of Normobaric Hypoxia on Oculomotor Dynamics of Aviator Students during a Simulated Flight Task [PDF]

open access: yes, 2020
Hypoxia occurs when the body\u27s tissues are unable to obtain adequate oxygen supply and is the primary environmental factor present when pilots are exposed to increasing altitude levels.

Physiological hypoxia restrains the senescence-associated secretory phenotype via AMPK-mediated mTOR suppression.

open access: yesMolecules and Cells, 2021
Cellular senescence is a state of stable proliferative arrest triggered by damaging signals. Senescent cells persist during aging and promote age-related pathologies via the pro-inflammatory senescence-associated secretory phenotype (SASP), whose ...

Deaths from Environmental Hypoxia and Raised Carbon Dioxide [PDF]

open access: yesAcademic Forensic Pathology, 2018
This paper reviews deaths in which there is an environment that is low in oxygen and/or has elevated levels of carbon dioxide. These deaths present problems to autopsy pathologists, as the autopsy is typically negative and postmortem toxicology cannot be used to detect the effects of hypoxia and raised levels of carbon dioxide. Deaths from hypoxia and

A Comprehensive Review on Environmental and Microenvironmental Oxygen Sensing Pathways Mediated by Hypoxia-Inducible Factors (HIFs)

open access: yesمجله دانشکده پزشکی اصفهان, 2019
Oxygen deficiency, referred to as hypoxia, can be divided into two categories of environmental (exogenous) which is sensitized by respiratory cells, and microenvironmental (endogenous) responses by other cells in the body, like cancer cells.

The role of physiological traits in assortment among and within fish shoals [PDF]

open access: yes, 2017
Individuals of gregarious species often group with conspecifics to which they are phenotypically similar. This among-group assortment has been studied for body size, sex and relatedness.
