abstract   the mutagenic and immunosuppressory effects of cyclophosphamide (cyp) are still the primary limitation to wider application for treating a variety of human malignancies. on the one hand, cyp treatment predisposes transplant recipients and cancer patients to risk of bacterial, fungal, and viral infections, in the other word the, lipopolysaccharide (lps), an endotoxin found in cell wal...

this study aimed to observe the protective effects of sufentanil pretreatment on rat cerebral injury during cardiopulmonary bypass (cpb) and to explore the underlying mechanism. twenty-four male adult sprague dawley (sd) rats were divided into 4 groups. then, the rat cpb model was established. a 14g trocar was inserted into the atrium dextrum. for rats in s1 and s5 groups, sufentanil (1 µg•kg-1...

the purpose of this study was to assess the in vitro effect of ascorbic acid on the antibacterial substantivity of tetraclean in bovine root dentin pretreated with sodium hypochlorite (naocl).eighty dentin tubes prepared from bovine incisor teeth were infected with enterococcus faecalis for 14 days. the specimens were divided into five groups as follows: tetraclean; 5.25% naocl/tetraclean; 5.25...

Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

conclusions the pattern of pretreatment with o2 could change this potential and highly protective strategy against cp-induced nephropathy to an ineffective or even mildly deteriorating one. therefore, o2 administration before cp injection to patients with cancer, for therapeutic purposes or as a preconditioning approach, should be performed and investigated with caution until exact effects of d...

Distillery wastewater from the bioethanol industry contains a high level of organic content which can be converted into biogas. However, presence toxic compounds in this could inhibit biogas production. Therefore, prior detoxification distillery is required. Fenton, one Advanced Oxidation Process (AOP) methods, was selected due to its performance degrade pollutants, short reaction time, and pro...
