Intestinal epithelial barrier dysfunction and vitamin D (VitD)-deficiency play a critical role in a large number of diseases. The histone deacetylases (HDAC) are associated with a large number of immune diseases. This study tests a hypothesis that the interaction between VitD and HDAC is associated with the regulation of epithelial barrier functions. In this study, human intestinal epithelial cell line, T84 cells, was cultured into monolayers to be used as a model to test the epithelial barrier functions. We observed that in a VitD-deficient environment, the T84 monolayer barrier function was compromised...

Context: Low vitamin B12 (B12) during pregnancy is associated with higher maternal obesity, insulin resistance(IR) and gestational diabetes(GDM). B12 is a key co-factor in 1-carbon metabolism. Objective: We hypothesize that B12 plays a role in epigenetic regulation by altering circulating miRNAs(miRs) during adipocyte differentiation and results in an adverse metabolic phenotype. Design, settings and main-outcome measure: Human pre-adipocyte cell-line(Chub-S7) were differentiated in various B12 concentrations: Control(500nM), LowB12(0...

Our recent studies demonstrated that intestinal epithelial vitamin D receptor (VDR) signaling plays a critical role in regulating colonic inflammation by protecting epithelial barrier integrity. Epithelial VDR is down-regulated in colitis, but how mucosal inflammation affects local 1,25-dihydroxyvitamin D (1,25(OH)2D3) production is unknown. Here we showed that Cyp27b1, a cytochrome P450 enzyme required for 1,25(OH)2D3 biosynthesis, is highly induced in colonic mucosa in inflammatory response. While VDR is reduced in colon biopsies from patients with ulcerative colitis, Cyp27b1 is markedly up-regulated in these samples...

Although the intestine plays the major role in 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) action on calcium homeostasis, the mechanisms involved remain incompletely understood. The established model of 1,25(OH)2D3 regulated intestinal calcium absorption postulates a critical role for the duodenum. However it is the distal intestine where 70 -80% of the ingested calcium is absorbed. In order to test directly the role of 1,25(OH)2D3 and the vitamin D receptor (VDR) in the distal intestine, 3 independent knockout (KO) /transgenic (TG) lines expressing VDR exclusively in the ileum, cecum and colon were generated by breeding VDR KO mice with TG mice expressing human (h)VDR under the control of the 9...

Globally, 32.4 million individuals are blind and 191 million have moderate or severe visual impairment (MSVI); 80% of cases of blindness and MSVI are avoidable. However, great efforts are needed to tackle blindness and MSVI, as eye care in most places is delivered in isolation from and without significant integration with general health sectors. Success stories, including control of vitamin A deficiency, onchocerciasis, and trachoma, showed that global partnerships, multisectoral collaboration, public-private partnerships, corporate philanthropy, support from nongovernmental organizations-both local and international-and governments are responsible for the success of these programs...

Insulin Resistance is common in patients with mild-to-moderate stage chronic kidney disease (CKD), even when the glomerular filtration rate is within the normal range. This study aimed to investigate the association of IR and 25-hydroxyvitamin D levels. In this study, we evaluated the frequency of IR in predialysis patients and the association with 25-hydroxyvitamin (OH)D levels. A total of 32 non-diabetic patients with predialysis were included in the study. Homeostasis model assessment for insulin resistance (HOMA-IR) index was calculated to show presence of IR...

BACKGROUND/AIMS: There are no reports from Saudi Arabia documenting the picture of osteopathy in celiac disease (CD) and the adherence of physicians to the guidelines and recommendations to screen for bone disease. We conducted this study to document the prevalence of CD-related osteopathy and the Saudi physicians' adherence to the screening recommendations. PATIENTS AND METHODS: We identified the biopsy proven CD cases diagnosed between 2003 and 2012. In addition to demographic data, we collected laboratory (serum calcium, phosphate, alkaline phosphatase, 25-dihydroxy vitamin D, and parathyroid hormone levels) and imaging [Dual-energy X-ray absorptiometry (DEXA)] data...

Growth hormone and insulin-like growth factor-1 (IGF-1) play a crucial role in the regulation of bone turnover. Adequate vitamin D status supports proper bone remodeling, leading to normal longitudinal bone growth and normal peak bone mass. The aim of this study was to evaluate the association between serum 25-hydroxyvitamin D [25(OH)D] and carboxy-terminal cross-linked telopeptide of type I collagen (ICTP) in children and adolescents with growth hormone deficiency at baseline and during recombinant human growth hormone (rhGH) replacement therapy...

Background and Aims: There has been increasing evidence that vitamin D deficiency may increase the risk of metabolic syndrome. Since metabolic syndrome is a major risk factor for non-alcoholic fatty liver disease (NAFLD), we aimed to investigate the association between vitamin D and the severity and mortality of NAFLD. Methods: Data was obtained from the United States Third National Health and Nutrition Examination Survey conducted in 1988-1994, with follow-up mortality data through 2011. NAFLD was defined by ultrasonographic detection of hepatic steatosis in the absence of other liver diseases and categorized as normal, mild, moderate or severe...

In the majority of patients with raised intracranial pressure, the papilledema is bilateral. Unilateral papilledema is rare in conditions causing intracranial hypertension, and it has been described in Foster-Kennedy syndrome and in some cases of idiopathic intracranial hypertension. It has never been reported in cerebral venous thrombosis. We report a young lady presenting with features of subacute onset of headache with seizures, on evaluation she had superior sagittal and bilateral lateral sinus thrombosis...

BACKGROUND: In addition to its well-established role in maintaining skeletal health, vitamin D has essential regulatory functions in female reproductive and pregnancy outcomes. Phthalates and bisphenol A (BPA) are endocrine disruptors, and previous research has suggested that these chemical agents may disrupt circulating levels of total 25(OH)D in adults. OBJECTIVES: We investigated the relationships between repeated measures of urinary phthalate metabolites and BPA and circulating total 25(OH)D in a prospective cohort of pregnant women...

A dog was referred for nutrition consultation after surgical removal of struvite uroliths from the bladder. Inspection of the dog's current ration revealed a pronounced vitamin-A deficiency together with a marked deficiency of protein, phosphorus and magnesium. Therefore, a supersaturation of the urine with ammonium, magnesium and phosphate, the three constituents of struvite, as a cause of struvite calculi formation appears rather unlikely. Vitamin-A deficiency can promote urinary infections and consequently struvite stone formation because of the lack of the protective effect of vitamin A on the epithelia of the urinary tract...

Peripheral neuropathy (PN) is a primary complication of type 2 diabetes mellitus (T2DM) and a direct manifestation of vitamin B12 deficiency. Examining the effects of metformin use on PN status became imperative following clinical studies that showed the vitamin B12-lowering effect of the medication. The complexity of the topic and the inconsistency of the results warrant consideration of topic-specific perspectives for better understanding of the available evidence and more appropriate design of future studies...

A study of the literature indicates that chloroplasts synthesise a range of molecules, many of which have nutritional value for humans, but the nutritional credentials of chloroplasts recovered from plant cells are not established. Chloroplast-rich-fractions (CRFs) were prepared from green plant species and the macro- and micro-nutrient composition compared with the whole leaf materials (WLMs). The results indicated that, on a dry weight basis, CRF material from a range of green biomass was enriched in lipids and proteins, and in a range of micronutrients compared with the WLM...
