Although several studies have demonstrated a potential correlation of dietary patterns with cognitive function, the relationship between tooth loss and dietary patterns and cognitive function have not been identified. In this cross-sectional study, we used a reduced rank regression (RRR) analysis, a technique used previously to observe dietary patterns based on the intakes of nutrients or levels of biomarkers associated with the condition of interest, to identify tooth loss-related dietary patterns and investigate the associations of such patterns with cognitive impairment in 334 community-dwelling Japanese subjects aged ≥ 60 years...

We report a 78 year-old non-atopic female with polyneuropathy who started to receive monthly intramuscular injections of thiamine hydrochloride. She had an anaphylaxis after the fourth injection. Skin prick test (SPT) with pure commercially available aqueous preparations was positive for thiamine hydrochloride. A titrated, single blinded, placebo-controlled oral provocation test with thiamine hydrochloride was well tolerated. The patient was then diagnosed as compartment allergy with hypersensitivity to parenteral but not to oral thiamine...

The microbiota of Drosophila melanogaster has a substantial impact on host physiology and nutrition. Some effects may involve vitamin provisioning, but the relationships between microbe-derived vitamins, diet, and host health remain to be established systematically. We explored the contribution of microbiota in supplying sufficient dietary thiamine (vitamin B1 ) to support D. melanogaster at different stages of its life cycle. Using chemically defined diets with different levels of available thiamine, we found that the interaction of thiamine concentration and microbiota did not affect the longevity of adult D...

RATIONALE: Circulatory failure, especially with low systemic vascular resistance (SVR), as observed in septic shock, thyrotoxicosis, and anemia, is a particular pattern that should suggest thiamine (vitamin B1) deficiency. The clinical picture of wet beriberi secondary to thiamine deficiency only demonstrates non-specific clinical manifestations. For a diagnosis of wet beriberi, medical history is very important. Interestingly, imprisonment was also found to be related to thiamine deficiency...

Nuts consumption plays an important role in Mediterranean diet, being a good source of proteins, vitamins, minerals and unsaturated fatty acids. However, nuts can be also a source of harmful mycotoxins with negative impact on human health. In this work, the occurrence of 16 mycotoxins belonging to different chemical classes, was assessed in several nut products. The analytical method used was based on modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) procedure followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis...

Currently accepted that oxidative stress is a triggering event in the melanocytic destruction and is probably involved in the etiopathogenesis of vitiligo disease. Despite numerous investigations, contradictory results were reported about the levels of oxidative stress biomarkers measured in the skin and blood of vitiligo patients. By Electron Paramagnetic Resonance spectroscopy (EPR) and spectrophotometry, we have investigated and compared some oxidative stress biomarkers in the blood of vitiligo patients' before and after UVB Narrow Band 311 nm phototherapy combined with the antioxidant nutritional supplement containing - Vitamin C, Vitamin B1, L -Cysteine, Lipoic Acid, and polyunsaturated fatty acids...

Nutrients involved in one-carbon metabolism may play a role in carcinogenesis through DNA replication, repair and methylation mechanisms. Most studies on urothelial cell carcinoma (UCC) have focused on folate. We sought to examine the association between B-group vitamins and methionine intake and UCC risk, overall and by subtype, and to test whether these associations are different for population subgroups whose nutritional status may be compromised. We followed participants in the Melbourne Collaborative Cohort Study (N=41,513) for over 20 years, and observed 500 UCC cases (89% originating in the bladder; superficial: 279, invasive: 221)...

BACKGROUND: Supplementation with vitamin B1 protects the peritoneal membrane from inflammatory and oxidative insults and preserves residual kidney function in rat models of peritoneal dialysis (PD). It is assumed that an active form of vitamin B1, thiamin diphosphate (ThDP), is responsible for this protective effect. However, it has never been shown whether ThDP, a compound known not to cross cellular membranes, is actually detectable in human peritoneal effluent. OBJECTIVES: This study was designed to investigate the concentration, appearance rate, and daily loss of ThDP in the peritoneal effluent of patients treated with PD...

Thiamine/ vitamin B1 deficiency can lead to behavioral changes and neurotoxicity in humans. This may due in part to vascular damage, neuroinflammation and neuronal degeneration in the diencephalon, which is seen in animal models of pyrithiamine-enhanced thiamine deficiency. However, the time course of the progression of these changes in the animal models has been poorly characterized. Therefore, in this study, the progression of: 1) activated microglial association with vasculature; 2) neurodegeneration; and 3) any vascular leakage in the forebrain during the progress of thiamine deficiency were determined...

We report simple and selective method for detection of vitamins B1 and B6 in brown and white rice samples using localized surface plasmon resonance (LSPR) of sucrose capped gold nanoparticles (AuNPs) as a chemical sensor colorimetrically. Here, detection is based on the color change of AuNPs from pink to blue followed by a red shift of LSPR absorption band in UV-vis region with the addition of vitamins B1 and B6 into the NPs solution. A good linear range was observed in the range of 25-1000 ngmL-1 with detection limit of 8 ngmL-1 for B1 and 50-1000 ngmL-1 with detection limit of 15 ngmL-1 for vitamins B6...
