Effect of Vitamin D Supplementation on Pancreatic Β -Cell Function in Patients with Type 1 Diabetes Mellitus and Vitamin D Deficiency: A Clinical Trial Study
Background Considering the increasing prevalence of type 1 diabetes mellitus (T1DM) as an autoimmune disease in recent years and the positive effects of vitamin D (VD) on this disease, especially the preventive effect of VD on progressive reduction of pancreatic β-cells, we aimed to investigate the effect of VD on pancreatic β-cell function in T1DM patients. Materials and Methods From Sep 2016 ...
متن کاملβ-d-Altrose
The mol-ecule of the title compound, C(6)H(12)O(6), [systematic name: (2R,3S,4R,5R,6R)-6-(hydroxy-meth-yl)oxane-2,3,4,5-tetrol] adopts a (4)C(1) chair conformation with the anomeric hydroxyl group in the equatorial position. All hydroxyl groups act as donors and acceptors in hydrogen bonding and the mol-ecule is involved in ten inter-molecular O-H⋯O inter-actions [O⋯O = 2.672 (5)-2.776 (4) Å] w...
متن کاملβ-d-Gulose
The title compound, C6H12O6, a C-3 position epimer of d-galactose, crystallized from an aqueous solution, was confirmed as β-d-pyran-ose with a (4) C 1 (C1) conformation. In the crystal, O-H⋯O hydrogen bonds between the hy-droxy groups at the C-1 and C-6 positions connect mol-ecules into a tape structure with an R 3 (3)(11) ring motif running along the a-axis direction. The tapes are connected ...
متن کاملCharacterization of the GDP-D-Mannose Biosynthesis Pathway in Coxiella burnetii: The Initial Steps for GDP-β-D-Virenose Biosynthesis
Coxiella burnetii, the etiologic agent of human Q fever, is a gram-negative and naturally obligate intracellular bacterium. The O-specific polysaccharide chain (O-PS) of the lipopolysaccharide (LPS) of C. burnetii is considered a heteropolymer of the two unusual sugars β-D-virenose and dihydrohydroxystreptose and mannose. We hypothesize that GDP-D-mannose is a metabolic intermediate to GDP-β-D-...

BACKGROUND In bacteria with truncated lipopolysaccharide structures, i.e., lacking the O-antigen polysaccharide part, core structures are exposed to the immune system upon infection and thus their use as carbohydrate surface antigens in glycoconjugate vaccines can be considered and investigated. One such suggested structure from Haemophilus influenzae LPS is the phosphorylated pentasaccharide 6...
