conclusions a majority of ovarian masses, especially those diagnosed within a short duration after hysterectomy, are benign. iranian patients with such ovarian masses when asymptomatic and associated with negative tumor markers could be followed up, and prophylactic oophorectomy may not be necessary. results of the 1052 patients with ovarian masses, 45patients (mean age, 53.11 ± 9.56 years) who...

objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

background: besides of transmitting several diseases to animals, and tick paralysis, ornithodoros lahorensis induce skin lesions. this experiment was done to determine histopathological features of adult o. lahorensis bite on rat. methods: in this investigation adult male rats were infested with o. lahorensis ticks. animals were divided into two groups and euthanized two days and two weeks afte...

Selective COX-2 inhibitors are most widely used analgesic and anti-inflammatory drugs;however, its maximal use is highly associated with various serious abnormal cardiovascularevents. Beraprost sodium (BPS), prostacyclin analogue has been shown to vasodilatory,antiplatelates, anti-inflmmatory, and antioxidant activity. The objective of the present study wasto evaluate the effect of BPS on celec...

Mycotoxins contamination of feedstuff for aquatic animals is common in regions with humid tropical conditions. In this study Indian white shrimp, Fenneropenaeus indicus, (11.79 ± 1.76 g) were fed with diets containing 0, 20, 50, 100, 200, 400, 800 and 1600 ppb levels of aflatoxin B1 (AFLB1) for 8 weeks. Final weight, aflatoxin B1 residue (2-week intervals), Total Hemocyte Count (THC), Total Pla...

PURPOSE Although mitochondrial DNA mutations have been described recently in many different tumor types, the nature and timing of such alterations remain unclear. In an effort to further examine the role of mitochondrial DNA mutations in carcinogenesis, we examined 137 premalignant lesions of the head and neck from 93 patients for DNA alterations in the poly-cytosine tract (C-tract) of the disp...

Aberrant proteins encoded from genes altered in tumors drive cancer development and may also be therapeutic targets. Here we derived a comprehensive gene-alteration profile of lung cancer cell lines. We tested 17 genes in a panel of 88 lung cancer cell lines and found the rates of alteration to be higher than previously thought. Nearly all cells feature inactivation at TP53 and CDKN2A or RB1, w...

statement of problem: recently, it has been proposed that different adhesive materials can be used for direct pulp capping. previous studies have demonstrated that multi steps dentin adhesives could form reparative dentin similar to calcium hydroxide (ch). purpose: the aim of this study was to evaluate the histological pulp response of ninety mechanically exposed cat pulps to two adhesive resin...
