piper/nicotine

The prevalence of kava (Piper methysticum), alcohol and tobacco consumption in Nuku'alofa (urban) and Foa (rural) are described. Current kava consumption was males 48% and females 1%. Prevalence was significantly higher among rural males. Current alcohol consumption was almost exclusive to the urban

Saliva of volunteers chewing betel quid, cured betel nut (Areca catechu), betel leaves (Piper betle), a mixture of quid ingredients (dried betel nut flakes, catechu, cardamon, lime, copra and menthol) and Indian tobacco was collected and examined for its genotoxic activity. Chromosome aberrations

Spices are rich sources of antioxidants due to the presence of phenols and flavonoids. In this study, the DNA protecting activity and inhibition of nicotine-induced cancer cell migration of 9 spices were analysed. Murine fibroblasts (3T3-L1) and human breast cancer (MCF-7) cells were pre-treated

OBJECTIVE To evaluate the effect of two inhaled essential oils (black pepper or angelica) on the nicotine habits of students, staff, and faculty on a U.S. college campus. METHODS Comparative study with pre-/post-test measures. METHODS Community college in rural East Texas. METHODS Convenience sample

When delivered to the oral mucosa, a variety of naturally occurring chemicals such as capsaicin from red chili peppers, piperine from black pepper, and nicotine from tobacco, cause a diffuse burning sensation often referred to as irritation. The burning sensation evoked by capsaicin increases when

Evaluations of biological effects of (Pb-CVO) the crude volatile oil of Piper betle leaves on the tobacco cutworm Spodoptera litura were conducted. Pb-CVO was subjected to GC-MS analysis and twenty vital compounds were isolated from the betel leaf oil. Pb-CVO was tested at four different

Cancer of the esophagus has a more varied geographical distribution and incidence than any other commonly occurring cancer. Its incidence rate is increasing in many countries, especially among males. Esophageal cancer has been found to be associated with the consumption of alcohol and tobacco,

Cucumber mosaic virus (CMV) causing mosaic, leaf distortion and stunting of vanilla (Vanilla planifolia Andrews) in India was characterized on the basis of biological and coat protein (CP) nucleotide sequence properties. In mechanical inoculation tests, the virus was found to infect members of

The ingestion of hot food and beverages has repeatedly been postulated as a risk factor for cancer of the esophagus. Although several studies have been performed on the correlation of the consumption of hot tea and esophageal cancer, no research has heretofore documented, by actually measuring, the

BACKGROUND Oral submucous fibrosis (OSF) is a chronic disease characterized by subepithelial collagen deposition with formation of bands involving the oral cavity and adjacent structures. Oral submucous fibrosis is a precancerous condition. It is caused by chewing of betel quid (Areca catechu L.,
