The long-term follow-up of two UK cohorts found some excess risk of liver cancer among severe, but not among mild, epileptics. Some excess risk of liver cancer was also found in cohort studies of patients hospitalized for epilepsy in Sweden and Taiwan, in the

absence, however, of association with any specific drugs. A UK General Practice database, comparing epileptics treated with valproate with unexposed ones, found a very low incidence of liver cancer. Of the studies of cancer in patients treated with phenobarbital, a large US pharmacy-based cohort investigation showed no excess risk of liver cancer. selleck products In a case-control study, nested in the Danish cohort of epileptics, no association was observed between phenobarbital and liver cancer among patients who had not received thorotrast (RR=1.0 for liver and 0.8 for biliary tract cancers). Thus, some, although not all, studies reported excess risk of all cancers and liver cancer in severe, but not in milder epileptics. There is no evidence of a specific role of phenobarbital in human liver cancer risk, but data on the topic are limited.”
“The chemical composition of the essential oils obtained from the fresh leaves of Cinnamomum tamala Nees et Eberm. was determined by GC and GC-MS. The yield of the oil on a dry weight basis ranged from 1.2% to 3.9% (w/w). Phenyl propanoids constitute the major portion

(88.9-95.0%) of the oils. Fifty-four compounds were identified from the oils. Eugenol (91.4-41.8%) was the main compound, followed by eugenyl acetate (0.0-47.1%) and alpha-phellandrene (0.6-2.5%) in the analysed oils.”
“This selleck screening library study examined the influence of manufacturing processes and extraction conditions on the chemical compositions of green tea. Green

tea samples grown in various areas (Korea, China, and Japan) and processed by 4 different methods (steaming, pan-firing, steaming and pan-firing, and heavy roasting after steaming and pan-firing) were collected for study. The chemical compositions of the green tea extracts and infusions were different according to their processing methods and extraction conditions, including www.selleckchem.com/products/ly2606368.html catechins, caffeine, and free amino acids contents. In all samples analyzed, (-)-epigallocatechin gallate (EGCG), (-)-epigallocatechin (EGC), and theanine were determined as the major catechins and free amino acid, respectively. Studies of samples grown in the same area (Jeju; Korea) showed that there were significant differences in the concentrations of catechins and caffeine in extract and infusion according to the processing methods. These results indicate that processing methods influenced the chemical compositions of the green tea extracts and infusions.”
“Colorectal cancer (CRC) accounts for 9.7% of all cancer cases and for 8% of all cancer-related deaths. Established risk factors include personal or family history of CRC as well as lifestyle and dietary factors.
