In this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid PEG1000-DAIL[BF4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. This novel methodnot only enhanced the yield, but also made the operating units easy workup. The catal...

purpose: to evaluate the effect of early aqueous suppressants initiation on ahmed glaucoma valve success rate. methods: in this randomized clinical trial, a total of 94 eyes of 94 patients with refractory glaucoma were enrolled. the eyes were randomly selected into 2 groups. in group 1 (n=47), patients received early topical combination of timolol-dorzolamide twice daily after ahmed glaucoma va...

purpose: to evaluate the diagnosis of intraocular tuberculosis (tb) with polymerase chain reaction (pcr) and to report 13 cases of presumed intraocular tb. methods: of 168 patients with uveitis, 13 patients (7.74%) had criteria for intraocular tb (tb group). thirteen patients with non-tb uveitis were randomly selected as the control group. samples for pcr were obtained from the aqueous humor. s...

A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

The juxtacanalicular connective tissue (JCT) is widely believed to generate the bulk of aqueous humor outflow resistance, while the pores of the inner wall endothelium are thought to generate at most 10% of this resistance in humans. However, the hydrodynamic interaction of these two components of the aqueous outflow system, which arises because of their spatial proximity, has only recently bee...

The aim of this study has been to determine whether eye chambers constitute part of the normal migratory pathway of naive CD4+ and CD8+ T cells in mouse and if natural CD4+CD25+Foxp3+ and CD8+CD25+Foxp3+ regulatory T cells are present within these eye compartments. To this aim, the cells obtained from aqueous humor (AH) of normal mice were phenotyped in terms of the expression CD4, CD8, CD25, C...

Both intraocular pressure and aqueous humour turnover rate were determined at intervals over three months in three females in order to investigate whether a correlation existed between these variables and the menstrual cycle. Not only was there a lack of correlation between intraocular pressure or aqueous humour flow rate and menses but intraocular pressure and aqueous humour flow rate were als...

nano sio2/hyperbranched polyglycerol (hpg)/so3h catalyst was readily prepared for first time from inexpensive starting materials in aqueous media which catalyzed the synthesis of benzoic acid. ftir spectra, x-ray diffraction (xrd) and transmission electron micrographs (tem) was employed to characterize the properties of the synthesized nano sio2/hpg/so3h. high catalytic activity and ease of rec...

helminths infections are chronic illness in human being and cattle. the use of alternate drugs has been a remedial measure against the resistant strains of helminth parasites, as well as means of reducing the cost of controlling diseases caused by helminthes. pseudocedrelakotschyi is a medicinally valuable plant and possesses various pharmacological properties. p. kotschyi has been traditionall...
