Hypoxia refers to the decrease in oxygen tension in the tissues, and the central effector of the hypoxic response is the transcription factor Hypoxia-Inducible Factor α (HIF1-α). Transient hypoxia in acute events, such as exercising or regeneration after damage, play an important role in skele...
Hypoxia refers to low oxygen levels in tissues throughout the body, which leads to the following signs and symptoms: Shortness of breath (dyspnea):Similar to hypoxemia, difficulty breathing is a hallmark symptom of hypoxia as well. Confusion or cognitive impairment:As with hypoxemia, the brain i...
Hypoxia refers to oxygen limitation in tissue. In animals, oxygen can be exchanged in the lungs, and more than 95% of the oxygen will enter the capillaries through the exchange system of alveolar-capillary. Most tissues of the body obtain sufficient oxygen from capillaries to meet their basic ...
Hypoxiarefers to a reduction of oxygen below the level necessary to support cell function. Cell death will result in proportion to the duration and severity of the insult. Although clear physical and neurological impairments, such ascerebral palsyand mental retardation, result from prolonged and sever...
Hypoxia refers to a deficiency in the amount of oxygen reaching tissues. In turn, limited oxygen supply initiates a cascade of mechanisms that may result in irreversible brain damage by causing apoptosis (cell-death). This cascade of mechanisms is mediated largely by N-methyl-D-aspartate ...

Anemic hypoxia refers toA.The hypoxia caused by the lack of oxygen at high altitude.B.The hypoxia caused by the damaging of the ability to carry oxygen of the blood.C.The hypoxia caused by the impotence of the tissue to adopt the oxygen in the blood.的答
Hypoxia refers to a deprivation of oxygen that can affect the body as a whole (generalised hypoxia) or a tissue (tissue hypoxia). Oxygen is critical for many biological process at the molecular, cellular and tissue levels 1. Low levels of oxygen have been linked to many pathological ...
Para-tumour tissues refers to the normal samples 2cm away from its paired tumour samples. All of the patients underwent surgery at the First Affiliated Hospital of Nanjing Medical University from 2006 to 2017. The expression level of SKA3 was determined by a semiquantitative scoring system. The ...
