Professor Pashutin's principal works are dedicated to disturbances of metabolism and thermoregulation, oxygen starvation and vitamin deficiency. He created an important scientific school, among whose adherents were Pyotr Albitsky, Stepan Kostyurin, Nikolai Kravkov, Sergey Lukyanov, Alexander Reprev, Nikolai Ushinsky and others.

Interruptions of coronary circulation quickly cause heart attacks (myocardial infarctions), in which the heart muscle is damaged by oxygen starvation. Such interruptions are usually caused by ischemic heart disease (coronary artery disease) and sometimes by embolism from other causes like obstruction in blood flow through vessels.

Consciousness is retained for up to 15 seconds as the effects of oxygen starvation set in. Counteracting this requires a helmet to contain breathing gases and protect the ears and eyes.Space Activity Suit, Astronautics.com These effects have been confirmed through various accidents in very high altitude conditions, outer space, and training vacuum chambers.

Making their way to the surface of Deimos, Fly and Arlene discover that Deimos had been moved by the demons to Earth's orbit, and that the invasion of Earth was already underway. The pressure dome covering the Deimos facility is slowly leaking oxygen, and the pair will eventually die from oxygen starvation if they do not escape.

Leaching or the soaking in water removes chemical inhibitors in some seeds that prevent germination. Rain and melting snow naturally accomplish this task. For seeds planted in gardens, running water is best – if soaked in a container, 12 to 24 hours of soaking is sufficient. Soaking longer, especially in stagnant water, can result in oxygen starvation and seed death.

Inhibition of coagulation and resultant internal bleeding can cause too few red blood cells to be present in the bloodstream and low blood pressure in newborns with fetal warfarin syndrome. Low hemoglobin levels can lead to partial oxygen starvation, a high level of lactic acid in the bloodstream, and acidosis. Prolonged oozing of fluid from the stump of the cut umbilical cord is common.

She was taken to nearby Alfred Hospital, and was found to have suffered oxygen starvation to the brain, head injuries and severe dehydration. She went into a medically induced coma, and was placed on life support. On 16 February 2005, police charged Joe Korp, 47, and his mistress Tania Herman, 38, with the attempted murder of Korp, conspiracy to murder, and intentionally causing serious injury. Both appeared the following day in Melbourne Magistrates' Court and were remanded in custody.

He passed out from oxygen starvation and only revived when the aircraft descended to lower altitude over the North Sea. Bohr's son Aage followed his father to Britain on another flight a week later, and became his personal assistant. Bohr was warmly received by James Chadwick and Sir John Anderson, but for security reasons Bohr was kept out of sight. He was given an apartment at St James's Palace and an office with the British Tube Alloys nuclear weapons development team.

Angiogenesis (blood vessel formation) is an essential part of the formation of large tumour masses. Angiogenesis can be inhibited by the expression of several genes, which can be delivered to cancer cells in viral vectors, resulting in suppression of angiogenesis, and oxygen starvation in the tumour. The infection of cells with viruses containing the genes for angiostatin and endostatin synthesis inhibited tumour growth in mice. Enhanced antitumour activities have been demonstrated in a recombinant vaccinia virus encoding anti-angiogenic therapeutic antibody and with an HSV1716 variant expressing an inhibitor of angiogenesis.

It contains two main interlocking parts: the hippocampus proper (also called Ammon's horn)Pearce, 2001 and the dentate gyrus. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy. People with extensive, bilateral hippocampal damage may experience anterograde amnesia: the inability to form and retain new memories.

The human body can briefly survive the hard vacuum of space unprotected, despite contrary depictions in some popular science fiction. Human flesh expands to about twice its size in such conditions, giving the visual effect of a body builder rather than an overfilled balloon. Consciousness is retained for up to 15 seconds as the effects of oxygen starvation set in. No snap freeze effect occurs because all heat must be lost through thermal radiation or the evaporation of liquids, and the blood does not boil because it remains pressurized within the body.

As a result of the oxygen starvation that both men suffered, neither saw the approach of an enemy night-fighter, whose attack badly damaged the Lancaster, one cannon shell passing through the rear- gunner's turret. The aircraft managed to return home and make a crash-landing at Bisham, the crew escaping unhurt. Dunstan completed a full tour of 30 operations and returned to Australia in August 1944, and was awarded the Distinguished Service Order for his efforts as a "Cool and skilful Air Gunner despite handicap of one leg". He was discharged from the Royal Australian Air Force on 2 October 1945.

As several of the candidates selected for the programme including Gagarin did not have higher education degrees, they were enrolled into a correspondence course programme at the Zhukovsky Air Force Engineering Academy. Gagarin enrolled in the programme in September 1960 and did not earn his specialist diploma until early 1968. Gagarin was also subjected to experiments that were designed to test physical and psychological endurance including oxygen starvation tests in which the cosmonauts were locked in an isolation chamber and the air slowly pumped out. He also trained for the upcoming flight by experiencing g-forces in a centrifuge.

Substance abusers also sometimes use the gas as an inhalant. Like all other inhalants, it's popular because it provides consciousness-altering effects while allowing users to avoid some of the legal issues surrounding illicit or illegal drugs of abuse. Abuse of nitrous oxide can produce significant short-term and long-term damage to human health, including a form of oxygen starvation called hypoxia, brain damage, and a serious vitamin B12 deficiency that can lead to nerve damage. Although dangerous and addictive in its own right, nitrous oxide has been shown to be an effective treatment for a number of addictions.

Their blood was also found to contain heavy concentrations of lactic acid, a sign of extreme physiologic stress. Although they could have remained conscious for almost 40 seconds after decompression began, less than 20 seconds would have passed before the effects of oxygen starvation made it impossible for them to function. Alexei Leonov, who would have originally commanded Soyuz 11, had advised the cosmonauts before the flight that they should manually close the valves between the orbital and descent modules as he did not trust them to shut automatically, a procedure he thought up during extensive time in the Soyuz simulator. However, Dobrovolsky, Volkov, and Patsayev either chose to disregard his warnings or else forgot about them during the lengthy mission.

Consciousness is retained for up to 15 seconds as the effects of oxygen starvation set in. No snap freeze effect occurs because all heat must be lost through thermal radiation or the evaporation of liquids, and the blood does not boil because it remains pressurized within the body but when the veins explode, due to the flesh expanding to about twice its size, the blood, stomach contents, brain, heart, eyeballs and muscles will begin to boil until one's body explodes due to 0 pressure in space.

He swam all but 5 m underwater for the first three 50 m lengths, and also swam half underwater for the last length, winning the gold medal. The adoption of this technique led to many swimmers suffering from oxygen starvation and even to some swimmers passing out during the race, so a new rule was introduced by the FINA, limiting the distance that can be swum underwater after the start and after every turn, and requiring the head to break the surface every cycle. Since then, the development of breaststroke has gone hand-in-hand with the FINA rules. In about the mid-1960s, the rules changed to prevent the arm stroke from going beyond the hip line, except during the first stroke after the start and after each turn.

He swam all but 5 m under water for the first three 50 m laps, and also swam half under water for the last lap, winning the gold medal. The adoption of this technique led to many swimmers suffering from oxygen starvation or even some swimmers passing out during the race due to a lack of air, and a new breaststroke rule was introduced by FINA, additionally limiting the distance that can be swum under water after the start and every turn, and requiring the head to break the surface every cycle. The 1956 Games in Melbourne also saw the introduction of the flip turn, a sort of tumble turn to faster change directions at the end of the lane. In 1972, another famous swimmer, Mark Spitz, was at the height of his career.

Following extensive training using an innovative torpedo-type sled design of very high descend and ascend speed, on June 6 Nitsch managed to reach a depth of , but ten minutes after the dive he began experiencing serious symptoms of decompression sickness. Nitsch temporarily fell asleep due to nitrogen narcosis during the last part of the ascent (as opposed to through oxygen starvation), and woke up prior to reaching the surface. Following a planned post-dive decompression, breathing medical oxygen at a shallow depth, he signaled to his support team that he felt much weaker than normal and his condition was assessed as critical enough to require an air transfer to a pre- alerted decompression chamber in Athens, where he received treatment. He incurred multiple brain strokes due to severe decompression sickness.
