BACKGROUND Ethyl carbamate (EC) is a multi-site carcinogen in experimental animals and probably carcinogenic to humans (IARC group 2A). Traces of EC below health-relevant ranges naturally occur in several fermented foods and beverages, while higher concentrations above 1 mg/l are regularly detected

The work history information from a population-based case-control study conducted in Puerto Rico was analyzed using a job exposure matrix to investigate the relationship between occupational exposures and cancers of the oral cavity or pharynx. After adjustment for age, alcohol, smoking, and

Certain Louisiana cancer rates are higher than the national averages. This review evaluates the existing epidemiologic literature pertaining to risk factors for cancer in Louisiana. Population-based case-control studies have identified smoking as the most important contributor to lung cancer in

To determine whether histologic patterns differed in the high- and low-lung cancer mortality parishes (counties) of Louisiana and whether the findings in the state differed from those in other parts of the United states, we studied the available histopathologic materials for 272 persons of the 815

The growth of animal cells in culture can be stimulated very powerfully when they are allowed to extend upon a solid surface. In normal fibroblasts, the maximum is reached either on a plane surface with an area of 2500 micron 2 or on a narrow fibre with a length of 250 micron. This

A case-control study was conducted of the risk of lung cancer and mesothelioma from environmental and occupational exposures associated with sugarcane production. A slight, not statistically significant, excess risk of lung cancer was observed among participants who reported working in the sugarcane

In a study to determine putative occupation-related factors responsible for the excessive mortality due to lung cancer in southern Louisiana, the next-of-kin were interviewed of 284 of 400 persons (71%) randomly sampled from a total of 815 persons who died of lung cancer during 1971 through 1977 and

In the United States, there is an epidemic of lung cancer, which causes more deaths annually than any other form of cancer. During 1950-1969, 27 of Louisiana's 64 parishes ranked in the upper 100 US countries for lung cancer mortality. Many of the rural southern parishes in the upper decile for lung

Sugarcane is an important crop grown in tropical regions for sugar, and for ethanol production. Sugarcane is also a source of phytochemicals but its nutraceutical potential has been under-explored. We show that ethanol extracts of whole dried sugarcane (WDS) recovers a rich content of polyphenols,

The lysosomal cysteine proteases cathepsin B and L play important roles in tumor cell invasion. An imbalance between these cathepsins and their endogenous inhibitors, the cystatins, has been associated with development of the metastatic phenotype. Accordingly, many studies have indicated potential

D-003, a mixture of high aliphatic primary acids purified from sugar cane wax, has shown cholesterol-lowering, anti-platelet and antioxidant effects. Previous data demonstrated that D-003 was not toxic or carcinogenic when given orally to Sprague-Dawley rats up to 1500 mg/kg. This study investigated

D-003 is a mixture of high molecular weight sugarcane wax aliphatic primary acids with cholesterol-lowering, anti-platelet and antioxidant effects. This study investigated the long-term oral toxicity and carcinogenicity of D-003 in Sprague Dawley rats of both sexes, randomly distributed into four

This work presents the influence of sugarcane burning on PAH levels and their profiles at a residence located in Araraquara (SP, Brazil), a city surrounded by sugarcane plantations. The average concentrations of total PAHs (ΣPAHs) associated with atmospheric particulate matter were higher during the
