.Silver Nanoparticles Attenuate Inflammation aggravation in Hepatocellular Carcinoma in Rats.

Hepatocellular Carcinoma in Sheep

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Silver nanoparticles can attenuate nitrative stress

We have reported previously that glucose availability can modify toxicity of silver nanoparticles (AgNPs) via elevation of antioxidant defence triggered by increased mitochondrial generation of reactive oxygen species. In this study, we examined the effect of glucose availability on the production of reactive nitrogen species in HepG2 cells and modification of nitrative stress by AgNPs. We foun...

Blood toxicity of silver nanoparticles in Pregnant Wistar Rats

Background: Investigation of toxicity of silver nanoparticle, especxially blood toxicity, is necessary because this nanoparticle is used a lot in diffrerent parts of life and invironment. The aime of this is evaluation the effects of silver nanoparticles with different concentrations on blood cells pregnant Wistar rats. Materials and Methods: In this case control study, 30 pregnant rat wer...

بررسی میزان بیان آنزیم دایسر در نواحی in situ carcinoma در مقایسه با مناطق in vasive carcinoma در سرطان پستان

خلاصه : کارسینوم تهاجمی سینه پستان علت مرگ و میر حاصل از سرطان خانم ها در بسیاری از کشورها می باشد. این کارسینوم بدنبال کارسینوم در محل ایجاد می شود. در کارسینوم در محل سلول های توموری هنوز نتوانسته اند که از غشاء پایه عبور کنند. در عبور از مرحله کارسینوم در محل به مرحله تهاجمی، سلولهای سرطانی تغییرات مولکولی بسیاری پیدا میکنند که هنوز علت عده ای از آنها مشخص نشده است. در این مطالعه ما بررسی کر...
