Male Fischer rats which had been implanted with a heterotopic bladder were randomly divided into five groups and their heterotopic bladders were instilled once a week for 20 weeks with 0.5 ml phosphate-buffered saline:dimethyl sulfoxide solution (4:1) or this solution containing 1 mumol benzidine (BZ), N'-hydroxy-N-acetylbenzidine, the N'-glucuronide of N'-hydroxy-N-acetylbenzidine, or the N-gl...

Silica sulfuric acid is employed as solid acid catalyst for the clean and less hazardousprotection of carbonyl compounds as 2,4-dinitrophenylhydrazone under solvent-free conditions.

The development of aqueous methods for generating enantiopure β-hydroxy carbonyl compounds is an important goal because these subunits compose many bioactive compounds and the ability to synthesize these groups in water has environmental and cost benefits. In this communication, we report a new class of ligands for aqueous, lanthanide-catalyzed, asymmetric Mukaiyama aldol reactions for the synt...

The title compound, C(13)H(24)O(7), is the product of the ketalization of methyl l-(+)-rhamnopyran-oside with 2,3-butane-dione. It crystallizes with two mol-ecules in the asymmetric unit, which are connected by O-H⋯O hydrogen bonds. The C-3,4 diequatorial hydroxy groups of the methyl l-(+)-rhamnopyran-oside were protected, leaving the C-2 hydroxy group free. The l-(+)-rhamnopyran-oside and 2',3...

background: vitamin d deficiency during pregnancy is associated with some adverse pregnancy outcomes but its relationship with fetal growth is unknown. objective: we compared the 25-hydroxy vitamin d levels between mothers and their small for gestational age (sga) newborns with mothers and their appropriate for gestational age (aga) newborns. materials and methods: the study population included...

Abstract. Biocides used in film protection products leaching from facades are known to be a potential threat the environment. This study identifies individual sources and entry pathways small-scale urban area. We investigate emissions of commonly biocides (terbutryn, diuron, octylisothiazolinone – OIT) some their transformation (TPs; diuron-desmethyl, terbumeton, terbuthylazine-2-hydroxy, terbu...

Aromatic diols containing bis (azo) and bis (o-nitrobenzyl) chromophores viz., (4hydroxyphenylazo)-2,2/-dinitrodiphenylmethane, 4-hydroxy-3-methylphenylazo-4/-hydroxyphenylazo-2,2/-dinitrodiphenyl methane and bis (4-hydroxy-3-methylphenylazo)-2-dinitrodiphenyl methane were synthesized from 4,4-diamino-2,2/-dinitrodiphenylmethane and phenol/0-cresol. As a result of photolysis, the azo group of t...

Recently, we identified 2-styrylchromones as a new class of antirhinovirus flavonoids with moderate activity against both rhinovirus groups A and B. In order to improve the antiviral effect of the first series of tested 2-styrylchromones, a hydroxy or methoxy group was introduced in position 3 of the chromone ring. Cytotoxicity and antiviral activity of the new synthesized compounds were evalua...

This study aimed to investigate whether the administration of mononuclear cells derived from human umbilical cord blood cells (UCBCs) could ameliorate hypoxic-ischemic brain injury in a neonatal rat model. The left carotid arteries of 7-day-old rats were ligated, and the rats were then exposed to 8% oxygen for 60 min. Mononuclear cells derived from UCBCs using the Ficoll-Hypaque technique were ...
