xylene/neoplasms

BACKGROUND Benzene, toluene and xylene (BTX) are aromatic hydrocarbons with inconclusive evidence of lung carcinogenicity. The aim of this research was to assess the associations between occupational exposures to BTX agents and lung cancer. METHODS In a population-based case-control study of lung

BACKGROUND Geranium wilfordii is one of the major species used as Herba Geranii (lao-guan-cao) in China, it is commonly used solely or in polyherbal formulations for treatment of joint pain resulted from rheumatoid arthritis (RA) and gout. This herb is used to validate a target-based drug screening

BACKGROUND An association between cancer and increased blood coagulation has been observed for many years. Generally, there is an equilibrium between the coagulation system (fibrin deposition) and the fibrinolytic system (degradation of fibrin by enzymes). However, in malignant disease such as

Although there is data suggesting the in vitro inhibition of aromatase in cell lines by antidiabetic biguanide metformin (MF), there is no data on the intratumoral breast cancer (BC) aromatase expression in patients already receiving therapy for type II diabetes. Paraffinized tumor samples obtained

Many studies have reported the biological activities of retrofractamide C (RAC). However, few studies have investigated the anti-inflammatory effect of RAC. In the present study, we investigated the anti-inflammatory effect of RAC using lipopolysaccharide (LPS)-induced J774A.1 cells and a

The objective of our study was to evaluate the association between occupation and risk of liver cancer. A hospital-based case-control study was carried out during 1997-1999 in the Province of Brescia, a highly industrialized area in Northern Italy with a high incidence of this neoplasm. The cases

The technical grade of xylenes (mixed) (hereafter termed xylenes) contains the three isomeric forms and ethylbenzene (percentage composition shown above). The annual production for 1985 was approximately 7.4 x 108 gallons. Xylenes is used as a solvent and a cleaning agent and as a degreaser and is a

The present study was done to ascertain whether a specific carcinogenic agent has a causal effect on the initial proliferation of only one cell type or whether it acts indiscriminately on all cells in the breast secretory unit. Enzymes histochemistry and electron microscopy were performed on

Musk xylene (MX) (1,3,5-trinitro-2-t-butylxylene) is a nitromusk perfume ingredient that although uniformly negative in a battery of genotoxicity tests, produces a high incidence of liver tumors in mice. The purpose of this work was to characterize the profile and dose-response relationship of

Radiolabeled organic cations, such as triphenylphosphonium (TPP), represents a new class of radiotracers for imaging cancers and the transport function of multidrug resistance P-glycoproteins (particularly MDR1 Pgp) by single photon emission computed tomography (SPECT) or positron emission

Pyeongwisan (PW) is an herbal medication used in traditional East Asian medicine to treat anorexia, abdominal distension, borborygmus and diarrhea caused by gastric catarrh, atony and dilatation. However, its effects on inflammation-related diseases are unknown. In this study, we investigated the

Studies in humans and animals have shown that gasoline contains a number of cancer-causing and toxic chemicals such as 1,3-butadiene, benzene, toluene, ethylbenzene, xylenes, isoparaffins, methyltert-butylether, and others. The International Agency for Research on Cancer (IARC) in its Monograph

Developing biocompatible polymeric platforms for drug delivery with enhanced localized activity represents a key facet of advanced interventional therapy. In this work, the drug-eluting potential of an amine-functionalized poly- p-xylene commonly known as Parylene A (4-amino(2,2)paracyclophane) was

Azolium (imidazolium and benzimidazolium) salts are known as stable precursors for the synthesis of Metal-N-Heterocyclic Carbene (M-NHC) complexes. Recently, some reports have been compiled indicating that benzimidazolium salts have anticarcinogenic properties. The current research is the further

Polynuclear platinum(II) complexes represent a class of potential anticancer agents that have shown promising pharmacological properties in preclinical studies. The nature of cellular responses induced by these complexes, however, is poorly understood. In this research, the cellular responses of
