purpose: to determine the effect of trabeculectomy (tx) on cataract formation or progression in glaucoma patients. methods: this controlled clinical trial was performed on 82 eyes of 41 consecutive patients older than 50 years with glaucoma. trabeculectomy was indicated only in one of their eyes and iop in the other eye was controlled with medication. the operated eyes were considered as treatm...

background il-33 is a novel member of the il-1 family, which has been shown to play an important role in t helper 2 (th2)-associated immune responses. recent studies have suggested a possible role for il-33 in the pathogenesis of liver damage during acute and chronic hepatitis; furthermore, il-33 may be involved in the development and progression of liver fibrosis. objectives to evaluate serum ...

Background: Some studies on Multiple Sclerosis (MS) have suggested that adequate vitamin D intake can modulate the course of MS and decreases its incidence. However, there are limited studies with conflicting findings on the relation between MS severity, its course, and vitamin D intake.  Objectives: The current study aimed to compare vitamin D intake and sunlight exposure between MS phenotype...

multiple sclerosis (ms) is a chronic inflammatory disease that leads to degeneration of the brain and spinal tissue. imbalances of cd4+ t cells including thelper1 (th1)/thelper2 (th2) and thelper17 (th17)/tregulatory (treg), their secreted cytokines and gene expressions, are important aspects of in immunopathogenesis of ms. vitamin a and its metabolites can regulate the immune system and appear...

background: the aim of this study was to investigate the efficacy and safety of metronomic capecitabine chemotherapy in pretreated elderly patients with advanced gastric carsonoma. patients and methods: eligible patients were treated with capecitabine at a fixed dose of 1000mg daily until disease progression or toxicity. endpoints were overall response rate, safety, progression-free survival an...

results like other cancers, prostate cancer is caused by an accumulation of genetic alterations in a cell that drives it to malignant growth. specific genes and gene alterations have been suggested to play a role in its development and progression. aneuploidy, loss of heterozygosity, gene mutations, hypermethylation and inactivation of specific tumour suppressor genes such as gstpi, apc, mdr1, ...

This paper starts with developing kinematic and dynamic model of a snake shape robot in serpentine locomotion and finishes with actual experimentation. At the beginning the symmetrical and unsymmetrical serpenoid curves are introduced. Kinematics and dynamics of a snake robot on flat and inclined surfaces are obtained for a general n-link robot. SimMechanics toolbox of MATLAB software is employ...

to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...
