Ergocalciferol - Wikipedia, the free encyclopedia - 0 views

  •  
    "Ergocalciferol (Deltalin, Eli Lilly and Company) is a form of vitamin D, also called vitamin D2. It has the systematic name "(3β,5Z,7E,22E)-9,10-secoergosta-5,7,10(19),22-tetraen-3-ol". It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol."

Vitamin D and influenza - Wikipedia, the free encyclopedia - 0 views

  •  
    "Numerous studies link Vitamin D and influenza, as well as Vitamin D and respiratory infections more generally. This vitamin up-regulates genetic expression of various endogenous antimicrobial peptides (AMP), which exhibit broad-spectrum microbicidal activity against bacteria, fungi, and viruses. Reports discussed below indicate that susceptibility to influenza is reduced with higher levels of sun exposure or vitamin D supplementation. Seasonal variation of vitamin D levels in humans can help explain the seasonality of flu epidemics."

Hypervitaminosis D - Wikipedia, the free encyclopedia - 0 views

  •  
    "Hypervitaminosis D is a state of vitamin D toxicity. The recommended daily allowance is 400 IU per day. Overdose has been observed at 1925 µg/d (77,000 IU per day). Acute overdose requires between 15,000 µg/d (600,000 IU per day) and 42,000 µg/d (1,680,000 IU per day) over a period of several days to months, with a safe intake level being 250 µg/d (10,000 IU per day).[1] Foods contain low levels, and have not been known to cause overdose. Overdose has occurred due to industrial accidents, for example when incorrectly formulated pills were sold or missing industrial concentrate cans misused as cans of milk. Vitamin D toxicity is unlikely except when certain medical conditions are present, such as primary hyperparathyroidism, sarcoidosis, tuberculosis, and lymphoma."

Hypovitaminosis D - Wikipedia, the free encyclopedia - 0 views

  •  
    "Hypovitaminosis D is a deficiency of Vitamin D. It can result from: inadequate intake coupled with inadequate sunlight exposure (in particular sunlight with adequate ultra violet B rays), disorders that limit its absorption, conditions that impair conversion of vitamin D into active metabolites, such as liver or kidney disorders, or, rarely, by a number of hereditary disorders.[1] Deficiency results in impaired bone mineralization, and leads to bone softening diseases, rickets in children and osteomalacia in adults, and contributes to osteoporosis.[1] Osteomalacia may also occur rarely as a side-effect of phenytoin use Hypovitaminosis D is typically diagnosed by measuring the concentration in blood of the compound 25-hydroxyvitamin D (calcidiol), which is a precursor to the active form 1,25-dihydroxyvitamin D (calcitriol).[6] One recent review has proposed the following four categories for hypovitaminosis D:[7] * Insufficient 50-100 nmol/L (20-40 ng/mL) * Mild 25-50 nmol/L (10-20 ng/mL) * Moderate 12.5-25.0 nmol/L (5-10 ng/mL) * Severe < 12.5 nmol/L (< 5 ng/mL) Note that 1.0 nmol/L = 0.4 ng/mL for this compound.[8] Other authors have suggested that a 25-hydroxyvitamin D level of 75-80 nmol/L (30-32 ng/mL) may be sufficient

Brain (as food) - Wikipedia, the free encyclopedia - 0 views

  •  
    "The brain, like most other internal organs, or offal, can serve as nourishment. Brains used for nourishment include those of pigs, squirrels, horses, cattle, monkeys, chickens and goats. In many cultures, different types of brain are considered a delicacy. In the Southern United States, canned pork brain in gravy can be purchased for consumption as food. This form of brain is often fried with scrambled eggs to produce "Eggs n' Brains".[1] They are part of the menu in many family owned restaurants throughout the region. The brain of animals also features in French cuisine, in dishes such as cervelle de veau and tête de veau."

Nutrition - Wikipedia, the free encyclopedia - 17 views

  •  
    Nutrition (also called nourishment or aliment) is the provision, to cells and organisms, of the materials necessary (in the form of food) to support life. Many common health problems can be prevented or alleviated with good nutrition.\nThe diet of an organism refers to what it eats. Dietitians are health professionals who specialize in human nutrition, meal planning, economics, preparation, and so on. They are trained to provide safe, evidence-based dietary advice and management to individuals (in health and disease), as well as to institutions.\nPoor diet can have an injurious impact on health, causing deficiency diseases such as scurvy, beriberi, and kwashiorkor; health-threatening conditions like obesity and metabolic syndrome, and such common chronic systemic diseases as cardiovascular disease, diabetes, and osteoporosis.

Apigenin - Wikipedia, the free encyclopedia - 0 views

  •  
    Apigenin is a flavone that is the aglycone of several glycosides. It is a yellow crystalline solid that has been used to dye wool. Apigenin is a potent inhibitor of CYP2C9,[2] an enzyme responsible for the metabolism of many pharmaceutical drugs in the body.

Vitamin D-dependent calcium-binding protein - Wikipedia, the free encyclopedia - 0 views

  •  
    "Vitamin D-dependent calcium binding proteins were discovered in the cytosolic fractions of chicken intestine, and later in mammalian intestine and kidney, by workers including Robert Wasserman of Cornell University. They bound calcium in the micromolar range and were greatly reduced in vitamin D-deficient animals. Expression could be induced by treating these animals with vitamin D metabolites such as calcitriol. They were found to exist in two distant sizes with a molecular weight of approximately 9 kDa and 28 kDa. They were renamed calbindin; calbindin-D9k is found in mammalian intestine and calbindin-D28k in avain intestine and in kidney."

Berberine - Wikipedia, the free encyclopedia - 0 views

  •  
    "Berberine is a quaternary ammonium salt from the group of isoquinoline alkaloids. It is found in such plants as Berberis, goldenseal (Hydrastis canadensis), and Coptis chinensis, usually in the roots, rhizomes, stems, and bark. Berberine is strongly yellow colored, which is why in earlier times berberis species were used to dye wool, leather and wood. Wool is still today dyed with berberine in Northern India Berberine (BBR) is a natural compound with up-regulating activity on both low-density-lipoprotein receptor (LDLR) and insulin receptor (InsR). This one-drug-multiple-target characteristic might be suitable for the treatment of metabolic syndrome.[12] Berberine has been tested and used successfully in experimental[13] and human diabetes mellitus.[14][15][16] Berberine has been shown to lower elevated blood glucose as effectively as metformin.[17] The mechanisms include inhibition of aldose reductase,[18] inducing glycolysis,[19] preventing insulin resistance[20] through increasing insulin receptor expression[14] and acting like incretins. Berberine has drawn extensive attention towards its antineoplastic effects.[43][44] It seems to suppress the growth of a wide variety of tumor cells including breast cancer,[45] leukemia, melanoma,[46] epidermoid carcinoma, hepatoma, oral carcinoma, tongue carcinoma,[47] glioblastoma, prostate carcinoma, gastric carcinoma.[48][49] Animal studies have shown that berberine can suppress chemical-induced carcinogenesis, tumor promotion, tumor invasion,[50][51][52][53][54] prostate cancer,[55][56][57][58] neuroblastoma,[59][60] and leukemia.[34][61] It is a radiosensitzer of tumor cells but not of normal cells
