Anoxia News and Research

RSS

Anoxia is a state of total oxygen deprivation within tissues or organs. It is an extreme form of hypoxia – a condition characterized by insufficient availability of oxygen. The damage caused by partial or complete lack of oxygen supply is known as hypoxic/anoxic injury.

Giving birth outside of working hours in England does not carry higher risk of infant mortality

A new study suggests that between 2005 and 2014, for almost all births in England, being born outside of working hours did not carry a significantly higher risk of death to the baby from anoxia (lack of oxygen) or trauma, when compared to births during working hours.

Is it possible for the human brain to be activated by the dying process?

Researchers examined the neuronal activity of the dying human brain.

Delay in consciousness in severe cases of COVID-19 may be caused by neural hibernation

An article published in the journal PNAS provides a conceptual analysis to interpret the brain state of coronavirus disease 2019 (COVID-19) patients experiencing prolonged recovery of consciousness.

Kyunurenic acid in cardiovascular therapy

In a recent study posted to the bioRxiv* preprint server, researchers assessed the impact of kynurenic acid on ischemic damage to the heart.

Eukaryotes emerged in a no-oxygen environment in the ocean, research suggests

The origin of complex cells started without oxygen, new research suggests.

Robotic exoskeletons improve motor function in adolescents with acquired brain injury

A team of New Jersey researchers has shown that gait training using robotic exoskeletons improved motor function in adolescents and young adults with acquired brain injury.

Meta-analysis of latest second-line treatments for status epilepticus

Status epilepticus (SE) is the most common neurologic emergency, with rates estimated between 1.3 and 81 cases per 100,000 people per year.

Study suggests new model of treatment for heart attack or stroke victims

Each year, heart attacks kill almost 10 million people in the world, and more than 6 million die from stroke. A heart attack is caused by a clot that blocks the artery blood flow. Unirrigated tissues are deprived from the oxygen that is carried by the blood. Under these conditions, the affected tissues undergo a rapid necrosis.

Groundbreaking experiment in pigs challenges the notion about brain damage

The brain is more resilient than previously thought. In a groundbreaking experiment published in this week's issue of Nature, neuroscientists created an artificial circulation system that successfully restored some functions and structures in donated pig brains--up to four hours after the pigs were butchered at a USDA food processing facility.

U of G study beginning to unravel mystery of hagfish’s zombie hearts

They are the scavengers of the deep and the dead. Hagfish are slimy bottom-dwellers that live off the carcasses of dead sea creatures and thrive in deep waters where oxygen is hard to come by. In fact, their hearts can keep on beating for 36 hours without any oxygen, making hagfish a champion among anoxia-tolerant fish.

Study describes new muscular disease caused by mutation in myoglobin gene

Researchers of the Bellvitge Biomedical Research Institute led by Dr. Montse Olivé have described in Nature Communications a new muscular disease caused by a mutation in the myoglobin gene.

Researchers explore freshwater turtles to understand mechanisms that protect from heart damage

In humans, going just minutes without oxygen-;such as during a heart attack or stroke-;can cause devastating damage to the heart.

Goldfish survive lack of oxygen for months by converting their carbs to alcohol

A new study has shown that goldfish and similar crucian carps can live up to five months in icy lakes with extremely low or no oxygen. Evolution of the fish has enabled them to develop a set of enzymes that can help the fish convert their carbohydrates into alcohol.

Mothers give offspring a head start in life

Thank your mothers: A research collaboration between UC Santa Barbara and L'École Normale Supérieure in Paris has proven that deterministic maternal effects can give offspring a better start on life.

Fruit flies helping FAU researchers to discover novel genes responsible for neuroprotection

They're pesky and annoying when they get into your fruit, but Drosophila melanogaster, more affectionately known as the "fruit fly," are helping researchers at Florida Atlantic University to discover novel genes that are responsible for neuroprotection.

Concise analysis of global disposable gloves market

MRRBIZ includes new market research report "Disposable Gloves Market For Medical and Non-Medical (Food, Cleanroom, Industrial And Other) Applications - Global Industry Analysis, Size, Share, Growth, Trends And Forecast 2013 - 2019" to its large collection of research report.

Anoxia-induced suspended animation helps survive hypothermia

How is it that some people who apparently freeze to death, with no heart rate or respiration for extended periods, can be brought back to life with no long-term negative health consequences? New findings from the laboratory of cell biologist Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center, may help explain the mechanics behind this widely documented phenomenon.

Glycolytic oscillations during ischemia can increase heart damage

Researchers in Germany show that a classical biological oscillator, the glycolytic oscillator, may increase damage to the heart during acute loss of oxygen (anoxia), and as may occur during ischemia.

Quebec transplantation: 431 people receive 499 organs from 138 deceased donors

Owing to the generosity of Quebecers, 499 organs from 138 deceased donors in 2009 were transplanted into 431 recipients. Though there were 13 fewer donors than in 2008, Québec posted an average of more than 3.6 transplanted organs per deceased donor in 2009, placing the province among the leaders in Canada and even North America. "We're particularly proud of the sustained collaboration of professionals in hospitals in 2009," says Louis Beaulieu, chief executive officer of Québec-Transplant, the organization responsible for coordinating the organ donation process.
