background: acute myeloid leukemia (aml) is known as one of the most common leukemia among adults. environmental and different genetic factors affect disease process, prognosis and treatment. among different genetic factors npm1, flt3, mll and baalc genes are the most effective on patient's survival rate. the aim of this study was to assess amount of baalc gene expression in aml patients, and i...

background: intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. in this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. methods: the present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...

purpose : to describe the survival characteristics and prognostic factors of patients with retinoblastoma in a referral center in iran methods : from medical records, we retrospectively analyzed the data of 139 consecutive children diagnosed in our hospital between 1991 and 2001 as having retinoblastoma. information on gender, laterality, age at diagnosis, presenting signs, tumor staging, treat...

purpose: to investigate the efficacy of topical cyclosporine a 2% in treating and preventing recurrent graft rejection episodes after penetrating keratoplasty (pkp) in patients with history of previous rejection episodes. methods: in this clinical trial, eligible pkp patients were randomly given topical cyclosporine a 2% or placebo in addition to a standard corticosteroid regimen for an episode...

The function of a distribution that describes postpartum interval (PPI) under any experimental treatment is useful for simulation modeling, understanding the effects of stimuli on the endocrine system, and estimating the average PPI in experiments terminated before all animals have expressed estrus. This study was undertaken to compare the fit of three statistical distributions, the Weibull, th...

Objectives. To assess the effect of Red Bull(©) on (1) blood glucose and catecholamine levels, (2) cardiovascular and respiratory function changes before, during, and after exercise, (3) reaction time, (4) cognitive functions, and (5) response to mental stress test and emotions in young healthy individuals (N=38).

background: this study aimed to assess the incidence and survival rates of neonates weighing less than 2500g for duration of the first 28 days in an iranian community. methods: in this prospective longitudinal study, all neonates with birth weight less than 2500g were selected from the list of all neonates born in the only public-sector referral hospital, for a six months period. the weight of ...

As an attempt to find an inexpensive and simple laboratory method for artificial insemination (AI) bull semen quality assessment, the osmotic resistance of spermatozoa was measured using the hypoosmotic swelling (HOS) test, developed by Jeyendran et al. (1984) (labelled HOS-1), and its modifications (HOS-2, HOS-3), with decreased osmotic pressure aimed at challenging sperm survival ability. The...

Beef production is an important development area in animal breeding with meat quality being determined by both paratypic and genetic factors. In this regard evaluating genetic material for the presence of desirable allele combinations of genes associated with growth and development indicators, as well as meat qualities of animals have a certain scientific and practical significance. The aim of ...

The Northern kelp crab (Pugettia producta) and the graceful kelp crab (Pugettia gracilis) are common primary consumers in bull kelp beds near the San Juan Islands (Salish Sea, NE Pacific). In this system, urchins (often considered the most voracious herbivores exerting top-down control on kelp beds) tend to remain sedentary because of the high availability of detrital macroalgae, but the extent...
