Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B 1). [1] A severe and chronic form is known as beriberi. [1] [7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness caused by the condition.
Pseudohypoxia refers to a condition that mimics hypoxia, by having sufficient oxygen yet impaired mitochondrial respiration due to a deficiency of necessary co-enzymes, such as NAD + and TPP. [ 1 ] [ 2 ] [ 3 ] The increased cytosolic ratio of free NADH/NAD + in cells (more NADH than NAD + ) can be caused by diabetic hyperglycemia and by ...
Thiamine, also known as thiamin and vitamin B 1, is a vitamin – an essential micronutrient for humans and animals. [1] [3] [4] It is found in food and commercially synthesized to be a dietary supplement or medication. [1]
Vitamin B 1: Thiamine: Thiamine plays a central role in the release of energy from carbohydrates. It is involved in RNA and DNA production, as well as nerve function. Its active form is a coenzyme called thiamine pyrophosphate (TPP), which takes part in the conversion of pyruvate to acetyl coenzyme A in metabolism. [11] Vitamin B 2: Riboflavin
Frequently, secondary to thiamine deficiency and subsequent cytotoxic edema in Wernicke encephalopathy, patients will have marked degeneration of the mammillary bodies. Thiamine (vitamin B 1) is an essential coenzyme in carbohydrate metabolism and is also a regulator of osmotic gradient. Its deficiency may cause swelling of the intracellular ...
The HIF transcriptional complex was discovered in 1995 by Gregg L. Semenza and postdoctoral fellow Guang Wang. [5] [6] [7] In 2016, William Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza were presented the Lasker Award for their work in elucidating the role of HIF-1 in oxygen sensing and its role in surviving low oxygen conditions. [8]
Vitamin B 1 analogues are analogues of vitamin B 1, thiamine. They typically have improved bioavailability relative to thiamine itself, and are used to treat conditions caused by vitamin B 1 deficiency. These conditions include beriberi, Korsakoff's syndrome, Wernicke's encephalopathy and diabetic neuropathy.
Vitamin B1 deficiency (thiamine deficiency) was reported to cause seizures, especially in alcoholics. [5] [6] [7] Vitamin B6 depletion (pyridoxine deficiency) was reported to be associated with pyridoxine-dependent seizures. [8] Vitamin B12 deficiency was reported to be the cause of seizures for adults [9] [10] and for infants. [11] [12]
