Induction of oxidative stress and inhibition of DNA repair are possible modes of arsenic-induced carcinogenesis. In West Bengal, India, several districts contain high levels of arsenic, which are far above the WHO-recommended standard. Prevention of arsenic-induced oxidative stress and induction of repair enzymes by curcumin, an active ingredient of(More)
Abstract Purpose. The plasma level of nitric oxide (NO), that has been reported to possess various antineoplastic properties, was found to be diminished due to the impairment of insulin-activated nitric oxide synthase (IANOS) as a result of the appearance of a novel antibody (free light chain of IgG, Mr 44 kD) against the enzyme in the circulation in(More)
Breast cancer remains the leading cause of cancer death among females worldwide. It signifies a shift from the previous decade during which the most common cause of cancer death was cervical cancer. Current treatment modalities, including surgery, radiotherapy, and adjuvant chemotherapy or hormone therapy, have not been successful enough to impart(More)
Groundwater arsenic contamination has been a health hazard for West Bengal, India. Oxidative stress to DNA is recognized as an underlying mechanism of arsenic carcinogenicity. A phytochemical, curcumin, from turmeric appears to be potent antioxidant and antimutagenic agent. DNA damage prevention with curcumin could be an effective strategy to combat arsenic(More)
Visual inspection after acetic acid application (VIA) and human papillomavirus (HPV) detection tests have been recommended to screen women for cervical cancer in low and middle income countries. A demonstration project in rural India screened 39,740 women with both the tests to compare their accuracies in real population setting. The project also evaluated(More)
In spite of screening and early diagnostic tests, the upward trend of breast cancer has become a matter of great concern in both developed and developing countries. The data collected by Population Based Cancer Registry in Chittaranjan National Cancer Institute, a regional cancer centre in Kolkata, from 1997 to 2004 gives an insight about the scenario of(More)
BACKGROUND Human papillomavirus (HPV) is a very common sexually transmitted disease affecting both men and women and is responsible for different ano-genital cancers in either sex. Co-existing sexually transmitted infections (STI) including HIV have been considered as important co-factors for carcinogenesis induced by HPV. The purpose of this study was to(More)
Chemotherapy is an integral part of modern day treatment regimen but anticancer drugs fail to demarcate between cancerous and normal cells thereby causing severe form of systemic toxicity. Among which pulmonary toxicity is a dreadful complication developed in cancer patients upon cyclophosphamide (CP) therapy. Oxidative stress, fibrosis, and apoptosis are(More)
PURPOSE Previously, we have synthesized and characterized a novel Cu(II) complex, copper N-(2-hydroxy acetophenone) glycinate (CuNG). Herein, we have determined the efficacy of CuNG in overcoming multidrug-resistant cancer using drug-resistant murine and human cancer cell lines. EXPERIMENTAL DESIGN Action of CuNG following single i.m. administration (5(More)
Preoperative lymph node screening of all neck compartments is favored by clinicians for the management of the neck. The presence of a metastatic node on one side of the neck reduces the 5-year survival rate to 50%, and the presence of a metastatic node on both sides of the neck reduces the 5-year survival rate to 25%. This study compared the evaluation of(More)
