Treatment of B12 deficiency is important to prevent progressive neurological and/or hematologic disease but requires a secure diagnosis. The aim of this study was to evaluate second line tests of B12 status as prognostic indicators of a hematologic response to vitamin B12 therapy. Forty-nine patients referred with low, serum vitamin B12 concentrations were treated with intramuscular B12 and re-...
We report on a child in whom severe nutritional vitamin B12 deficiency was exacerbated by a genetic impairment of the folate cycle, causing reduced CSF concentrations of the methyl group donor 5-methyltetrahydrofolate. Some patients with vitamin B12 deficiency may benefit from high dose folic acid supplementation, even if plasma concentrations are high.
Two alternative methods for detecting vitamin B(12) deficiency in a psychiatric population have been compared: the ;direct' approach by microbiological assay of serum vitamin B(12) levels in all patients, and the ;indirect' approach where all patients are first screened for antigastric parietal cell antibodies and thereafter all positive reactors and other ;high-risk' patients have serum vitami...
BACKGROUND Vitamin D deficiency has been described as being pandemic, but serum 25-hydroxyvitamin D [25(OH)D] distribution data for the European Union are of very variable quality. The NIH-led international Vitamin D Standardization Program (VDSP) has developed protocols for standardizing existing 25(OH)D values from national health/nutrition surveys. OBJECTIVE This study applied VDSP protoco...
objectives we assessed functional vitamin b12 deficiency in tehranian elderly admitted to elderly research center, university of social welfare and rehabilitation sciences. conclusions the prevalence of b12 deficiency was higher in this study compared to other studies, so more attention and massive efficacious policy should be designed to reduce the deficiency of this vitamin. results cut-off o...
Two patients with asymptomatic vitamin B(12) deficiency developed a peripheral neuropathy 6-7 weeks after exposure to nitrous oxide during general anaesthesia, and 3 and 11 days after receiving cyclophosphamide. The serum B(12) concentration was less than 20 pmol/l and the symptoms resolved after B(12) replacement. We believe that the neurological symptoms were triggered by exposure to nitrous ...
Abstract Although it is well established that nitrogen (N) deficiency induces leaf senescence, the molecular mechanism of N deficiency-induced senescence remains largely unknown. Here, we show an abscisic acid (ABA)-responsive NAC transcription factor (TF) involved in senescence. The overexpression MdNAC4 led to increased ABA levels apple calli by directly activating biosynthesis gene MdNCED2 ....
BACKGROUND Hypercholesterolemia-induced atherosclerosis is attenuated by either pharmacological antagonism of AT1 receptors or AT1A receptor deficiency. However, the mechanism underlying the pronounced responses to angiotensin II (Ang II) antagonism has not been determined. We hypothesized that hypercholesterolemia stimulates the production of angiotensin peptides to provide a rationale for the...
