The effect of thyroxine on magnesium requirement.
It has recently been demonstrated that animals maintained in the cold (12.8”) have an increased requirement for magnesium (1). Animals fed a purified diet grew maximally when the diet contained 25 mg. per cent of magnesium, whereas animals maintained in the cold required approximately 50 mg. per cent of magnesium to achieve maximal rates of growth although such animals never attained the weight...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولRequirement of neuroD for photoreceptor formation in the chick retina.
PURPOSE The genetic control of photoreceptor cell fate in the vertebrate retina is poorly understood. Published studies suggest that the genetic program underlying photoreceptor production involves neuroD, a proneural basic helix-loop-helix (bHLH) gene. The present study investigates whether neuroD is necessary for photoreceptor cell development, by using loss-of-function analyses. METHOD Eng...
متن کاملMagnesium Requirement of Young Women Receiving Controlled Intakes1
Magnesium is an important constituent of cardiac and skeletal muscle, of nerve tissue and bone. It is involved in protein, fat, nucleic acid and coenzyme synthesis; in glucose utilization and in neuromuscular activity. It is also an essential acti vator for several enzymes, some that transfer phosphate, some that are in volved with the decarboxylation of pyruvic acid and others concerned with r...
متن کاملAminoacylation of tRNA. Magnesium requirement and spermidine effect.
The aminoacylation of tRNA has been fommlated as a two step reaction [ 11. The first reaction is the activation of the amino acid, and the second is the transfer of the activated amino acid onto the tRNA. Takeda and co-workers have proposed that only the first reaction requires magnesium ions; whereas, the magnesium ions are not necessary for the overall reaction [2,3]. This concept has caused ...
