Cisplatin (CP) is a widly used anticancer drug against abroad spectrum of malignance, but at high dose, it can produce undesirable effects such as hepatotoxicity. The aim of this study was to investigate the possible protective effect of erdosteine (Erd) against CP-induced biochemical, histopathological changes and hepatotoxicity associated with oxidative stress and inflammatory changes in male...

Bisphenol A (BPA) is an estrogenic environmental toxicant, a synthetic monomer widely used to polymerize polycarbonate plastics and resins. BPA has been implicated to have hazardous effect on reproductive health in human and experimental rats. Lycopene is a powerful antioxidant and potential high-value compound for the prevention of many diseases. The present study has been designed to investig...

Plasmodium vivax is the most prevalent of the five species causing malaria in humans. The current available treatment for P. vivax malaria is limited and unsatisfactory due to at least two drawbacks: the undesirable side effects of primaquine (PQ) and drug resistance to chloroquine. Phenylalanine-alanine-PQ (Phe-Ala-PQ) is a PQ prodrug with a more favorable pharmacokinetic profile compared to P...

The Food and Drug Administration recently warned of the fatal cardiovascular risks of azithromycin in humans. In addition, a recently published study documented azithromycin-induced cardiotoxicity in rats. This study aimed to justify the exact cardiovascular events accompanying azithromycin administration in rats, focusing on electrocardiographic, biochemical, and histopathological changes. In ...

A 40-year-old woman presented with an itchy erythematosquamous change of a café-au-lait spot in her face. The onset of this change occurred just after her relocation. The café-au-lait spot had been irradiated by laser approximately 20 years ago. Clinically, there was a coin-sized erythema with a slight scale on the pigmented lesion in the left lateral orbital region. Histopathologically, the le...

Bitter crab disease (BCD) of snow crabs, Chionoecetes opilio, is caused by a parasitic dinoflagellate, Hematodinium sp. The disease has shown an alarming increase in prevalence in the commercial fishery in eastern and northeastern areas of Newfoundland and Labrador since it was first recorded there in the early 1990s. We documented histopathological alterations to the tissues in snow crabs with...

BACKGROUND Inactivation of the tumour suppressor gene p16 (CDKN2/MTS-1/INK4A) and K-ras mutations are among the most frequent genetic alterations in human malignancies. AIMS To investigate the tumour suppressor gene p16 and its possible association with K-ras mutations in intrahepatic cholangiocarcinomas of the liver. METHODS The status of p16 was evaluated in 41 cholangiocarcinomas by meth...

The acute and sub acute toxicity studies of ethyl acetate extract of Caesalpinia bonducella leaves in albino mice were investigated. Various doses of ethyl acetate leaf extract from 800 to 2000 mg/kg body weight were administered orally to the test groups of mice, while distilled water was given to the control group to evaluate the toxicity in mice after ingestion of the extract for one day (ac...

Consumption of repeatedly heated cooking oil (RHCO) has been a regular practice without knowing the harmful effects of use. The present study is based on the hypothesis that, heating of edible oils to their boiling points results in the formation of free radicals that cause oxidative stress and induce damage at the cellular and molecular levels. Peroxide value of heated oil, histopathological a...

Novel oncogene mutation detection techniques have demonstrated that standard histopathological examination may fail to detect clinically significant metastatic cancer cells. Recently, telomerase activity has been detected in most immortal cell lines and human tumors, potentially providing a novel diagnostic marker. We compared standard histopathological examination with the telomeric repeat amp...
