Aging reduces hypoxia-induced microvascular growth in the rodent hippocampus.
The effect of aging on microvascular density and plasticity in the rodent hippocampus, a brain region critically important for learning and memory, was investigated in F344xBN rats. Capillary density and angiogenesis were measured in three regions of the hippocampus in young and old rats and in old rats administered growth hormone, a treatment that improves cognitive function in older animals. ...
متن کاملHypoxia reduces placental mTOR activation in a hypoxia‐induced model of intrauterine growth restriction (IUGR)
Mammalian target of rapamycin (mTOR) is a protein that regulates cell growth in response to altered nutrient and growth factor availability. Our objective was to assess activated mTOR and its intracellular intermediates p70, and 4EBP1 in placental and invasive trophoblast cells in a hypoxia-induced model of intrauterine growth restriction (IUGR) in rats. Rats were treated with hypoxia (9%) for ...
متن کاملIntermittent hypoxia reduces microglia proliferation and induces DNA damage in vitro
Objective(s):Intermittent hypoxia (IH), caused by obstructive sleep apnea (OSA), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. Thus, the present study aimed to explore the effect of IH on the biological functions of microglia cells. Materials and Methods:Cell proliferation of BV2 cells after exposure to IH were o...
متن کاملEfficient Holistic Twig Joins in Leaf-to-Root Combining with Root-to-Leaf Way
Finding all the occurrences of a twig pattern on multiple elements in an XML document is a core operation for efficient evaluation of XML queries. Holistic twig join algorithms, TwigStack and TSGeneric, have been recognized as optimal solutions when the twig pattern only involves A-D(ancestor-descendant) relationships, while iTwigJoin can be optimal for partial twig patterns that contain A-D on...
متن کاملThe Essential oil Composition of Arctium lappa Root and Leaf
Using plants and natural products as medicine is increasing every day. The reason might be a tendency that the societies mostly have toward natural and original products especially natural drugs. Essential oilsare referred to aromatic composition which is found in different parts of a plant and can be used for different remedial and hygienic purposes. One of the plants which have been used a lo...
