Dr. Roy Gravel, also a co-author of the study and member of the Alberta Childrens Hospital Research Institute says this study provides a tremendous opportunity to look at the prevention of diseases like spina bifida. "The work began as a study of a gene called Mtrr in mice. The goal was to shed light on how a mutation in Mtrr would affect folate metabolism. The multigeneral effect we observed was completely unexpected," says Gravel. The Mtrr gene encodes an enzyme that is key to the metabolism of folic acid and, when mutated, causes similar effects to dietary folic acid deficiency. The researchers found that when either the maternal grandmother or the maternal grandfather had this Mtrr mutation, their genetically normal grandchildren were at risk of a wide spectrum of developmental abnormalities, even if the mutated gene was not inherited through to the next generations. These developmental abnormalities were also seen in the fourth and fifth generations of mice. Through a series of ...

TY - JOUR. T1 - Role of folate deficiency on erythropoietin resistance in pediatric and adolescent patients on chronic dialysis. AU - Bamgbola, Oluwatoyin Fatai. AU - Kaskel, Frederick. PY - 2005/11/1. Y1 - 2005/11/1. N2 - Unlike iron therapy, folate use is not a standard of care in hemodialysis (HD) patients. Despite iron repletion, poor response to erythropoietin (EPO) treatment is common. Theoretical evidence for folate deficiency (FD) includes chronic blood loss, inflammation, malnutrition, and nutrient loss during dialysis. Due to poor diagnostic standards, early studies failed to establish a role for FD in EPO resistance. Given that hematological response to therapeutic intervention is the gold standard for FD, its diagnosis was therefore based on composite scoring of RBC and/or folate indices. Fifteen subjects (8-20 years) on chronic HD were enrolled in this study. No folate supplement was given in the first six months. Thereafter, 5-mg folic acid was administered orally after HD sessions ...
A deficiency of folate can occur when the bodys need for folate is increased, when dietary intake or absorption of folate is inadequate, or when the body excretes (or loses) more folate than usual. Medications that interfere with the bodys ability to use folate may also increase the need for this vitamin.[5][6][7][8][9][10] Some research indicates that exposure to ultraviolet light, including the use of tanning beds, can lead to a folate deficiency.[11][12] The deficiency is more common in pregnant women, infants, children, and adolescents. It may also be due to poor diet or a consequence of alcoholism.[13] Additionally, a defect in homocysteine methyltransferase or a deficiency of Vitamin B12 may lead to a so-called "methyl-trap" of tetrahydrofolate (THF), in which THF is converted to a reservoir of methyl-THF which thereafter has no way of being metabolized, and serves as a sink of THF that causes a subsequent deficiency in folate.[14] Thus, a deficiency in B-12 can generate a large pool of ...
In a previous report, we suggested that platelet hyperactivity, possibly through stimulated free radical-induced arachidonate acid metabolism, might be involved in the known thrombogenic risk of OC intake.15 We were also the first to show that dietary FD potentiated platelet activation.7 The present study was designed to determine whether FD could amplify OC effects and whether an impaired folate metabolism could contribute to the thrombogenicity of OC. We found that feeding rats with a folic acid-deficient diet enhanced OC-induced platelet hyperactivity. Although a rat model has been used with a high dose of estrogen that may not be comparable with that for women, we also observed that OC treatment led to a loss of folates associated with moderate hyperhomocysteinemia. We further suggested that involvement of an impaired folate metabolism in the prothrombotic effects caused by OC might be secondary to the OC-induced oxidative stress, which would initially affect platelet activity.. An effective ...

Little is known about the biological effect of folate in the protection against mitochondrial (mt) oxidative decay. The objective of the present study was to examine the consequence of folate deprivation on mt oxidative degeneration, and the mechanistic link underlying the relationship. Male Wistar rats were fed with an amino acid-defined diet containing either 8 (control) or 0 (folate-deficient, FD) mg folic acid/kg diet. After a 4-week FD feeding period, significant elevation in oxidative stress was observed inside the liver mitochondria with a 77 % decrease in mt folate level (P , 0·001), a 28 % reduction in glutathione peroxidase activity (P = 0·0333), a 1·2-fold increase of mt protein carbonyls (P = 0·0278) and an accumulated 4834 bp large-scale deletion in mtDNA. The elicited oxidative injuries in FD liver mitochondria were associated with 30 % reduction of cytochrome c oxidase (CcOX) activity (P = 0·0264). The defective CcOX activity in FD hepatocytes coincided with mt membrane ...
Folic acid is a B vitamin that aids your body in producing new cells. You can find this vitamin in foods such as dried beans, peas, nuts, leafy green vegetables and fruits. Enriched breads, cereals and other grain products are also fortified with folic acid.
In a study of "Cerebral folate deficiency syndromes in childhood: clinical, analytical, and etiologic aspects" by Pérez-Dueñas B, Ormazábal A, Toma C, Torrico B, Cormand B, Serrano M, Sierra C, De Grandis E, Marfa MP, García-Cazorla A, Campistol J, Pascual JM, Artuch R., posted in US National Library of Medicine National Institutes of Health, researchers found that Of the 2 main forms of cerebral folate deficiency identified, mild to moderate 5-MTHF deficiency was most commonly associated with disorders bearing no primary relation to folate metabolism, whereas profound 5-MTHF depletion was associated with specific mitochondrial disorders, metabolic and transporter defects, or cerebral degenerations. The results suggest that 5-MTHF can serve either as the hallmark of inborn disorders of folate transport and metabolism or, more frequently, as an indicator of neurologic dysfunction ...
Abstract: Folate, a water soluble B vitamin, serves as a methyl donor for the synthesis of nucleotides and methionine. Folate deficiency has been linked to a variety of health problems that include developmental defects, cancer and neurological diseases. The relation between folate deficiency and human health problems has not been fully explained. Our preliminary results and limited published data have shown that the activity of NF-? B increases in folate deficient conditions. NF-?B is a cytosolic dimeric transcription factor that responds to a variety of stimuli by regulating genes involved in immune response, cell survival and cell growth. The purpose of the study was to determine if folate deficiency leads to altered NF-?B activity, protein levels and nuclear localization, and to determine the possible mechanisms behind this alteration. NIH3T3 cells containing a NF-?B reporter construct (NF-?B-LUC-3T3 cells) were grown for 7 and 11 days in folate sufficient and folate deficient DMEM medium ...

TY - JOUR. T1 - Folate deficiency triggers an oxidative-nitrosative stress-mediated apoptotic cell death and impedes insulin biosynthesis in RINm5F pancreatic islet β-cells. T2 - Relevant to the pathogenesis of diabetes. AU - Hsu, Hung Chih. AU - Chiou, Jeng Fong. AU - Wang, Yu Huei. AU - Chen, Chia Hui. AU - Mau, Shin Yi. AU - Ho, Chun Te. AU - Chang, Pey Jium. AU - Liu, Tsan Zon. AU - Chen, Ching Hsein. PY - 2013/11/4. Y1 - 2013/11/4. N2 - It has been postulated that folic acid (folate) deficiency (FD) may be a risk factor for the pathogenesis of a variety of oxidative stress-triggered chronic degenerative diseases including diabetes, however, the direct evidence to lend support to this hypothesis is scanty. For this reason, we set out to study if FD can trigger the apoptotic events in an insulin-producing pancreatic RINm5F islet β cells. When these cells were cultivated under FD condition, a time-dependent growth impediment was observed and the demise of these cells was demonstrated to be ...
MTR, also known as methionine synthase, is a methyltransferase enzyme, which uses the MeB12 and reaction type 2 to catalyze the conversion of the amino acid homocysteine (Hcy) back into methionine (Met) (for more see MTRs reaction mechanism). This functionality is lost in vitamin B12 deficiency, and can be measured clinically as an increased homocysteine level in vitro. Increased homocysteine can also be caused by a folic acid deficiency, since B12 helps to regenerate the tetrahydrofolate (THF) active form of folic acid. Without B12, folate is trapped as 5-methyl-folate, from which THF can not be recovered unless a MTR process reacts the 5-methyl-folate with homocysteine to produce methionine and THF, thus decreasing the need for fresh sources of THF from the diet. THF may be produced in the conversion of homocysteine to methionine, or may be obtained in the diet. It is converted by a non-B12-dependent process to 5,10-methylene-THF, which is involved in the synthesis of thymine. Reduced ...
Some people will gain benefit from sublingual tabs, others have to do injections. It basically is a matter of what part of the small bowel is impacted [and to what extent] by the Crohns. I take very high dosage B12 sublingual lozenges [1000 mcg] that I get at Super Supplements. These are methylcobalamin as opposed to cynacobalamin. B 12 in foods is in the form of cynacobalamin which the body must convert to methylcobalamin to utilize. The supplements I use are methylcobalamin so the body can absorb it - ready to use. Also, I take a PPI for GERD and gastritis caused by CD. PPIs can effect the absorption of B12 supplements so that is why I take the high dose that I do. My GI and neurologist both agree that this is what I need to do. In addition, I take folic acid supplements because B12 deficiency can go hand-in-hand with folic acid deficiency ...
In the present work we measured blood levels of total homocysteine ((t)Hcy), vitamin B(12) and folic acid in patients with Parkinson s disease (PD) and in age-matched controls and searched for possible associations between these levels with smoking, alcohol consumption, L-DOPA treatment and disease duration in PD patients. We initially observed that plasma (t)Hcy levels were increased by around 30 % in patients affected by PD compared to controls. Linear correlation, multiple regression and comparative analyses revealed that the major determinant of the increased plasma concentrations of (t)Hcy in PD patients was folic acid deficiency, whereas in controls (t)Hcy levels were mainly determined by plasma vitamin B(12) concentrations ...
Proper intake of vitamins and minerals can mean the difference between a healthy, productive life, and a life fraught with illness. Micronutrient deficiencies, which affect over two billion people around the globe today, are the leading cause of intellectual disability in children (due to iodine deficiency), preventable blindness (due to vitamin A deficiency), maternal death during childbirth (due to iron deficiency), and severe and often fatal birth defects known as neural tube defects (due to folic acid deficiency). Diminished mental capacity and increased absenteeism (due to iodine and iron deficiency), lead to lower academic achievement, with lifelong consequences.. A lack of these important vitamins and minerals also has a profound impact on the bodys immune system. A persons chances of dying from measles or diarrhea are between 30 - 50%. With adequate micronutrient intake, this percentage can be lowered significantly due to the effects vitamins and minerals have on bolstering the immune ...

Doctors give trusted, helpful answers on causes, diagnosis, symptoms, treatment, and more: Dr. Crane on would vomiting help clear liquor from system: Alcohol (etoh) empties rapidly from the stomach. Alcohol dehydrogenase in the stomach lining contributes to etoh metabolism. Etoh can not be stored by the body & obligatory oxidation takes place predominantly in the liver. 1 gram etoh gives 7 empty calories that provide only energy with no nutritional value. Poor diet (protein-calorie, choline, folate (folic acid) deficiency) contributes to liver toxicity.
Lesser amount of red blood cells or hemoglobin or iron means that your body is not getting enough oxygen, resulting in dysfunction of various organs. There can be various causes of anaemia, which may include iron deficiency, folic acid deficiency, extreme loss of blood, etc.
DNA damage induced by folate deficiency evokes two distinct DNA repair systems. The excessive uracil misincorporation induced by folate deficiency may evoke overinitiated BER, accumulating intermediate AP sites and SSB, and hence imposing greater dependence on the repair capacity of the downstream BER pathway. DSB caused by hypomethylation or adjacent SSB are repaired by the DSB repair pathway. We prospectively investigated the a priori gene-environment interaction hypothesis that the beneficial effect of plasma folate level on breast cancer risk may vary according to genetic variations in the coding regions of DNA repair genes (XRCC1, XRCC2, and XRCC3) in a nested case-control study within the Nurses Health Study.. In this prospective nested case-control study, we previously observed that XRCC1 194Trp carriers were at a decreased risk of breast cancer (carriers versus non-carriers, multivariate OR, 0.79; 95% CI, 0.60-1.04) (23), which is consistent with most of the published studies reporting ...

Women of childbearing age, people who abuse alcohol, anyone taking anti-convulsants or other medications that interfere with the action of folate or folic acid, individuals diagnosed with anemia from folate or folic acid deficiency, and individuals with malabsorption, liver disease, or who are receiving kidney dialysis treatment may benefit from a folic acid supplement. Folic acid is very important for all women who may become pregnant. Adequate folate and folic acid intake during the periconceptual period, the time just before and just after a woman becomes pregnant, protects against a number of congenital malformations including neural tube defects21. Neural tube defects result in malformations of the spine (spina bifida), skull, and brain (anencephaly)10. The risk of neural tube defects is significantly reduced when supplemental folic acid is consumed in addition to a healthful diet prior to and during the first month following conception5, 22, 23. Women who could become pregnant are advised ...
INTRODUCTION: In 2012, the Government of Kenya amended the Food, Drug and Chemical Substances Act to mandate the fortification of maize and wheat flour with folic acid. We assessed folate deficiency, awareness, and folic acid use among pregnant women receiving antenatal care (ANC) at a clinic at Pumwani Maternity Hospital, Kenya, 2015. METHODS: we conducted a cross-sectional survey at Pumwani Maternity Hospital between October and November 2014. We enrolled pregnant women who received ANC, and interviewed them using a semi-structured questionnaire after obtaining informed consent. Blood samples were collected from all study participants and serum folate level was analyzed by electrochemiluminescence immunoassay. Folate deficiency was defined as serum folate of < 10nmols/L and borderline folate deficiency was defined as serum folate of between 10nmols/L and 15nmols/L. RESULTS: among the 247 study participants, two (1%) had folate deficiency. One hundred and seventy-nine (73.4%) had heard about folic acid
Development of drug resistant bacteria Prescribing sulfamethoxazole and trimethoprim tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.. Folate deficiency Sulfamethoxazole and trimethoprim should be given with caution to patients with impaired renal or hepatic function, to those with possible folate deficiency (e.g., the elderly, chronic alcoholics, patients receiving anticonvulsant therapy, patients with malabsorption syndrome and patients in malnutrition states) and to those with severe allergies or bronchial asthma.. Hematological changes indicative of folic acid deficiency may occur in elderly patients or in patients with preexisting folic acid deficiency or kidney failure. These effects are reversible by folinic acid therapy.. Hemolysis In glucose-6-phosphate dehydrogenase deficient individuals, hemolysis may occur. This ...
This anemia is typically caused by a poor diet, in which adequate amounts of folic acid are lacking. Folic acid is present in foods such as green leafy vegetables; fresh fruits; cereals; meats, including liver; and yeast. It is also produced synthetically and added to many food items. Alcohol interferes with the absorption of folate, so persons who drink excessively are at risk for folate-deficiency anemia. Folate deficiency can also be seen in certain diseases of the lower digestive tract, such as celiac disease, or in persons with cancer.. Folate deficiency often occurs during pregnancy, because of the increased amount of folate needed by the fetus and because it is absorbed more slowly from the mothers digestive tract during pregnancy. Vomiting from morning sickness, anorexia, and poor dietary habits also contribute to folate deficiency during pregancy. There is an association between folate deficiency during pregnancy and neural tube defects in the developing fetus.. The inability to absorb ...
Less common symptoms include: headaches, palpitations, altered taste and ringing in the ears (tinnitus). You may look pale.. What are the causes of folic acid deficiency?. Not eating enough foods containing folic acid is the most common cause. Groups who often dont eat properly are people who are alcohol-dependent and/or elderly. Pregnancy causes reserves of folic acid in your body to be used by the growing baby. You are at risk of becoming low in folic acid during the later stages of pregnancy, particularly if you do not eat well during pregnancy. Some uncommon conditions of the gut may cause poor absorption of folic acid. For example, coeliac disease.. Some inflammatory conditions can lead to low folic acid levels - for example, severe Crohns disease. This is less common though.. Some medicines interfere with folic acid. Therefore, you may need to take extra folic acid whilst taking certain medicines. For example, colestyramine, sulfasalazine, methotrexate and some anticonvulsant medicines ...

Neurological disease was first linked to folate deficiency by Pincus and co-workers in 1973 (Reynolds et al, 1973) and low CSF folate levels were first reported in 1981 (Botez and Bachevalier 1981). Cerebral folate deficiency was subsequently defined by Raemakers and Blau (2004) as any neurological syndrome associated with a low CSF 5-MTHF, in the presence of normal folate metabolism outside the nervous system. However, it should be noted that cerebral folate deficiency is often used to describe conditions where CSF 5-MTHF is low, regardless of the peripheral folate status. A variety of causes of cerebral folate deficiency have been described, ranging from inborn errors of metabolism including metabolic recycling defects (DHFR and MTHFR deficiencies) and disorders of folate transport (e.g. FOLR1 and PCFT defects, and mitochondrial disorders leading to impaired folate transport) to possible over-utilisation/degradation defects such as L-dopa methylation and neurodegeneration.

This test looks at the number of red blood cells, their size and how much haemoglobin (to carry oxygen) is packaged into each one; the numbers of white cells; and also provides a break-down of the numbers of different types of cell, including the number of platelets (which allow blood to clot). One would expect to find abnormalities here in anaemia, B12 deficiency, folic acid deficiency, sometimes underactive thyroid, iron deficiency, infections, leukaemias, and - rarely - allergy or parasites. It is a screening test very commonly done in any medical work-up of a patient. Just because it shows "normal" results does not mean all is well. However, some doctors are very naughty and tell their patients, quite erroneously, "Oh! The blood test is fine, so there is nothing the matter!". ...
