Folate has gained significant attention due to its vital role in biological methylation and epigenetic machinery. Folate, or vitamin (B9 ), is only produced through a de novo mechanism by plants and micro-organisms in the rumen of mature animals. Although limited research has been conducted on folate in ruminants, it has been noted that ruminal synthesis could not maintain folate levels in high yielding dairy animals. Folate has an essential role in one-carbon metabolism and is a strong antiproliferative agent...

Sports activities associated with repetitive cranial trauma have become a fad and are popular in gyms and even among children. It is important to consistently characterize the consequences of such sports activities in order to better advise society on the real risks to the central nervous system. We present the case of a former boxer reporting cognitive and behavioral symptoms that began six years after his retirement as a boxer, evolving progressively with parkinsonian and cerebellar features suggestive of probable chronic traumatic encephalopathy (CTE)...

Emerging literature suggests that diet constituents may play a modulatory role in chronic pain (CP) through management of inflammation/oxidative stress, resulting in attenuation of pain. We performed a narrative review to evaluate the existing evidence regarding the optimum diet for the management of CP, and we built a food pyramid on this topic. The present review also describes the activities of various natural compounds contained in foods (i.e. phenolic compounds in extra-virgin olive oil (EVO)) listed on our pyramid, which have comparable effects to drug management therapy...

OBJECTIVES: Hemodialysis (HD) with dialysis adequacy could increase the excretion of B vitamins (folate, vitamin B6 , and B12 ) and raise the plasma level of homocysteine. Here we determined the associations of plasma homocysteine with B vitamins in patients with HD adequacy or inadequacy. METHODS: We recruited 68 patients who had received HD treatments (three times a week, 4 h each). Based on the individual's hemogram and quarterly urea reduction rate (Kt/V), patients were pooled into one of the following two groups: the first group with dialysis adequacy (Kt/V > 1...

OBJECTIVES: Extant evidence indicates that ketamine exerts rapid antidepressant effects in treatment-resistant depressive (TRD) symptoms as a part of major depressive disorder (MDD) and bipolar disorder (BD). The identification of depressed sub-populations that are more likely to benefit from ketamine treatment remains a priority. In keeping with this view, the present narrative review aims to identify the pretreatment predictors of response to ketamine in TRD as part of MDD and BD. METHOD: Electronic search engines PubMed/MEDLINE, ClinicalTrials...

Cobalamin, also known as the red-colored vitamin B12 , is found in animal-based foods such as meat, milk, and fish. Various cobalamin compounds are extracted from foods and converted into cyanocobalamin, which is most stable, to be analyzed by various methods. Traditionally, the cobalamin content of foods is determined by microbiological assay with Lactobacillus delbrueckii subsp. lactis American Type Culture Collection 7830. However, this lactic acid bacterium can substitute deoxyribosides or deoxynucleotides (known as an alkali-resistant factor) for cobalamin...

Vitamin B12 plays an important role in the mechanisms which are responsible for myelinization in the central nervous system. It can particularly lead to hematological and neuropsychiatric symptoms when serum levels fall due to insufficient intake with diet or absorption problems. The purpose of this study was to show the cognitive effects in vitamin B12 deficiency cases that have not reached clinical symptom level using neuropsychological tests, and to show possible cerebral neuronal damage using diffusion tensor imaging (DTI) method...

BACKGROUND: Stroke is still a major global health problem in both developed and developing countries. Defining stroke subtype and underlying etiologies is a major step to choose the best method for prophylaxis. Homocysteine is an endothelial toxin and elevated levels have been associated with stroke risk. In this study, we hypothesized that serum total homocysteine level may be related with specific atherothrombotic ischemic stroke subtypes and aimed to find if high serum homocysteine levels are correlated with any specific ischemic stroke subtype...

The most potential causes of "non hemolytic" anemias are iron, folate or vitamin B12 deficiencies, severe renal impairment, endocrine diseases, inflammation and medullary disorders. In a non-exceptionnal way no cause is found, sometimes because of a wrong interpretation of analysis results and sometimes because of a little known etiology. The goal of this review is to point out analytical difficulties and to remember some rarer etiologies.

Gram-negative bacteria import essential nutrients such as iron and vitamin B12 through outer membrane receptors. This process utilizes proton motive force harvested by the Ton system made up of three inner membrane proteins, ExbB, ExbD and TonB. ExbB and ExbD form the proton channel that energizes uptake through TonB. Recently, crystal structures suggest that the ExbB pentamer is the scaffold. Here, we present structures of hexameric complexes of ExbB and ExbD revealed by X-ray crystallography and single particle cryo-EM...

Aquatic environments contain large communities of microorganisms whose synergistic interactions mediate the cycling of major and trace nutrients, including vitamins. B-vitamins are essential coenzymes that many organisms cannot synthesize. Thus their exchange among de-novo synthesizers and auxotrophs is expected to play an important role in the microbial consortia and explain some of the temporal and spatial changes observed in diversity. In this study, we analyzed metatranscriptomes of a natural marine coastal microbial community, diel sampled quarterly over one year to try to identify the potential major B-vitamin synthesizers and consumers...
