Background : Some studies have shown that the serum concentration of 25- hydroxy vitamin D which is represent the status of body vitamin D, has a diverse relationship with obesity status, and the risk of obesity decreases in people with high level of 25- hydroxy vitamin D. The aim of this study is to investigate the correlation between the serum level of 25- hydroxy vitamin D and anthropometric...
Faujasite (FAU) zeolites (with Si/Al ratio of ca. 1.7) undergo mild dealumination at moderate ion exchange conditions (0.01 to 0.6 M NH4NO3 solutions) resulting in protons circumscribed by sodalite cages becoming accessible for reaction without conspicuous changes bulk crystallinity. The (HSOD) supercages (HSUP) can be systematically manipulated from 0 1 adjusting ammonium concentrations used e...
Excesses of sulfur-36 in sodalite, a chlorine-rich mineral, in a calcium- and aluminum-rich inclusion from the Ningqiang carbonaceous chondrite linearly correlate with chorine/sulfur ratios, providing direct evidence for the presence of short-lived chlorine-36 (with a half-life of 0.3 million years) in the early solar system. The best inferred (36Cl/35Cl)o ratios of the sodalite are approximate...
The reaction of 2-hydroxy-3-methoxybenzaldehyde with 4-nitrosulfonylhydrazide under refluxing led to co-crystalline compound contains N'-(2-hydroxy-3-methoxy benzylidene)-4-nitro benzenesulfonylhydrazide (a sulfonamide-Schiff base compound) and 1,2-bis (2-hydroxy-3-methoxy-benzylidenehydrazine) (I). A medium strong hydrogen bonds in 1 links the oxygen atoms of one molecule of 1,2-bis(2-hydroxy-...

Coronene was incorporated into cage-like sodalite-type porous organic salts (s-POSs) which have different degrees of heavy-atom effects depending on the substituents (methyl group and halogens) exposed pore surface. The combination external bromine iodine their oxygen barrier enabled coronene to exhibit room-temperature phosphorescence even in air, with a lifetime more than microseconds. More i...
