Sodium p-Chloro-m-Cresol, p-Chloro-m-Cresol (PCMC), Mixed Cresols, m-Cresol, o-Cresol, p-Cresol, Isopropyl Cresols, Thymol, Chlorothymol, o-Cymen-5-ol, and Carvacrol are substituted phenols used as cosmetic biocides/preservatives and/or fragrance ingredients. Only PCMC, Thymol, and o-Cymen-5-ol are
4,4'-Thiobis(6- t -butyl- m -cresol) (TBBC) is used in the rubber and plastics industries as an antioxidant. TBBC is also used as a stabilizer in polyethylene and polyolefin packaging materials for foodstuffs. Toxicology and carcinogenesis studies were conducted by administering TBBC (99% pure) in
Ryanodine receptors (RyRs) have been previously implicated in the proliferation of human T-lymphocytes and melanocytes as well as in the motility of astrocytes. We have examined RyR expression in 57 ductal, human breast cancer specimens, by immunohistochemistry. Moderate to high RyR immunostaining
Adult female B6C3F1 mice were gavaged with TBBC in corn oil at doses of 10, 100, or 200 mg/kg daily for 14 consecutive days. All immunological parameters were measured 24 hr after the last chemical exposure. When indicated, animals were immunized during the exposure. TBBC produced a decrease in the
Exposure to hydroxyl-substituted arenes, commonly referred to as phenols or phenolic compounds, can have serious health consequences. Select phenols present in tobacco smoke are cardiovascular toxins, act as tumor co-promoters and show genotoxic activity. To examine the mainstream smoke levels of
BACKGROUND
Waterpipe tobacco smoking has in recent years become a popular international phenomenon, particularly among youth. While it has been shown to deliver significant quantities of several carcinogenic and toxic substances, phenols, an important class of chemical compounds thought to promote
Drug resistance is a fundamental problem in cancer chemotherapy. Intracellular calcium concentration ([Ca2+](i)) may play a role in the development of chemoresistance. We investigated the regulatory role of [Ca2+](i) in Taxol resistance in the non-small-cell lung cancer cell line A549 and its
