N-acetylcysteine (NAC) has been known not only to stimulate synthesis of glutathione but also to affect the gene regulation. In our study, effects of NAC on the cytotoxicity of cadmium (Cd) were examined in LLC-PK1 cells. Preincubation and subsequent incubation with 1 mM NAC almost completely suppressed Cd-induced cellular damage evaluated either by trypan blue exclusion or lactate dehydrogenas...

Background: Several potential challenges with radiation protection (RP) and safety culture in radiology departments need to be addressed. This study assesses radiographers’ adherence to radiation protection practices in radiology departments. Materials and Methods: A cross-sectional study was conducted among radiographers; 210 self-administrated questionnaires were sent to the participants. An ...

A tent treated with an oil-based 1% permethrin formulation (0.936 g AI/m2) was evaluated for protection against Aedes spp. Mosquito biting assessment was conducted in the field using 8 human subjects positioned inside and outside tents. Subjects inside tents received 66.8% fewer bites than subjects outside tents prior to treatment. Following treatment, subjects inside the treated tent had signi...

After 10 years of clinical trials in patients with advanced cancer, monoclonal antibodies (mAbs) against cell surface antigens have not lived up to their initial promise. One such cell surface antigen is the ganglioside GD2. GD2 is richly expressed at the cell surfaces of human neuroblastomas, sarcomas, and melanomas. We have described a murine lymphoma (EL4) that is syngeneic in C57BL/6 mice a...

aloe buettneri a. berger is commonly used in traditional togolese medicine to treat inflammatory and gastric ulcers. the present study examined the gastro-protection effect of the hydro-alcoholic extract of a. buettneri on mucus production and gastric ph. a gastric ulcer is induced by ethanol 95° alone (1 ml/kg body weight), after pre-treatment with indomethacin (300 mg/kg) or by utilising l-na...

Cyanide is a highly toxic cellular poison that requires immediate and aggressive treatments. Combination of sodium nitrite (SN) and sodium thiosulfate (STS) is the treatment of choice but oral treatment of alpha-ketoglutarate (A-KG) has also been shown to significantly antagonize cyanide poisoning in laboratory animals. This study reports the efficacy of various treatment regimens as: (i) repea...
