in this study we have tried to identify the most important factors in employee turnover; and using deep understanding and then prioritizing of these factors, appropriate recommendations to reduce their negative effects will be presented. the above factors in the two main hypotheses and also five sub-hypotheses has been investigated and analyzed. in this study using descriptive method and also u...

Increasing evidence suggests that abnormal iron handling may be involved in the pathogenesis of Parkinson's disease. The present study investigates the role of iron and the iron-storage protein ferritin in inflammation-induced degeneration of dopaminergic neurons of the substantia nigra pars compacta. Injection of lipopolysaccharide into the globus pallidus of young and middle-aged rats substan...

PURPOSE To measure the incidence of pars planitis in a community-based population and to report clinical features, complications, and visual prognosis. DESIGN Population-based, retrospective, 20-year cohort study. METHODS Multicenter study using the Rochester Epidemiology Project medical records linkage system, which allows analysis of almost all patients within Olmsted County, Minnesota, w...

Calcium-binding protein (CaBP) and parvalbumin are two proteins that are expressed in brain and bind calcium in the micromolar range. The immunohistochemical distribution of these two proteins was examined in the basal ganglia of rats and rhesus monkeys. In the striatum, CaBP immunoreactivity is localized to a subset of striatonigral projection neurons; CaBP-positive neurons are distributed in ...

Most bacterial chromosomes carry an analogue of the parABS systems that govern plasmid partition, but their role in chromosome partition is ambiguous. parABS systems might be particularly important for orderly segregation of multipartite genomes, where their role may thus be easier to evaluate. We have characterized parABS systems in Burkholderia cenocepacia, whose genome comprises three chromo...

The protein encoded by open reading frame 50 (ORF50) of Kaposi's sarcoma-associated herpesvirus (KSHV) functions as a transcriptional activator and in lytic viral DNA replication to mediate the switch from latent viral infection to the lytic phase. Here we identify regulatory regions of ORF50 protein that independently control DNA binding and abundance of the protein. One region contains a DNA-...

Background: Modifications of the inner retinal layer is a frequent observation following pars plana vitectomy. Aim Work: To assess early changes thickness Retinal Nerve Fiber Layer after vitrectomy by ocular coherence tomography. Patients and Methods: This non-interventional observational study, in which 30 eyes patients underwent Examination Pars Plana Vitrectomy OCT. Cases were performed at O...

purpose : to evaluate the efficacy and safety of pars plana ahmed valve implant combined with pars plana vitrectomy and endolaser photocoagulation for the treatment of neovascular glaucoma in patients with vitreous hemorrhage. methods : retrospectively, we evaluated the records of 18 eyes of 17 consecutive neovascular glaucoma patients who had undergone pars plana vitrectomy and pars plana ahme...

PURPOSE The X and Y chromosomes have been associated with malignancy in different types of human tumors. This study attempts to determine the involvement of X chromosome and pseudoautosomal regions (PAR) in sporadic colorectal carcinogenesis. EXPERIMENTAL DESIGN An allelotyping of X chromosome in 20 premalignant and 22 malignant sporadic colorectal tumors (CRC) from female patients and an ana...

A parallel image reconstruction algorithm is presented that exploits the k-space locality in radiofrequency (RF) coil encoded data. In RF coil encoding, information relevant to reconstructing an omitted datum rapidly diminishes as a function of k-space separation between the omitted datum and the acquired signal data. The proposed method, parallel magnetic resonance imaging with adaptive radius...
