In spite of the development of upper digestive tract fiberoptic endoscopy (FE) within the last 10 years, early detection of esophageal carcinoma (EC) is rare except in certain high-risk groups such as patients with head and neck cancers. The aim of this study was to assess the value of a meticulous

BACKGROUND Taxanes are routinely used for the treatment of prostate cancer, however the majority of patients eventually develop resistance. We investigated the potential efficacy of EL102, a novel toluidine sulphonamide, in pre-clinical models of prostate cancer. METHODS The effect of EL102 and/or

Opportunistic screening for oral cancer has been advocated as a possible beneficial procedure, especially with high-risk individuals. To assist in the identification of malignant lesions a dye has been developed which can be used routinely. Issues of acceptability for both patient and practitioner

BACKGROUND Photodynamic therapy (PDT) is an emerging treatment that has demonstrated potential for the clinical treatment of buccal cancer. It is based on the photoactivation of a photosensitizer (PS) when irradiated by light at a specific wavelength. The light-excited PS generates reactive oxygen

Background: Oral potentially malignant disorders (OPMDs) and oral cancer (OC) are preventable oral mucosaldiseases prevalent in Asian region. This epidemiological study aims to identify oral potentially malignant disorders(OPMDs) and oral cancer (OC), confirm histopathologically, and treat or refer

In six carcinogenicity bioassays, male and female F344 rats were fed diets containing aniline hydrochloride (CAS: 142-04-1; hydrochloride benzenamide), p-chloroaniline (CAS: 106-47-8), azobenzene (CAS: 103-33-3), o-toluidine hydrochloride (CAS: 636-21-5), dapsone (CAS: 80-08-0;

A multifunctional nanosystem based on two-dimensional molybdenum disulfide (MoS2) was developed for synergistic tumor therapy. MoS2 was stabilized with lipoic acid (LA)-modified poly(ethylene glycol) and modified with a pH-responsive charge-convertible peptide (LA-K11(DMA)). Then, a positively

Some features of digestive cancers encourage screening programs, even though no such program has been shown so far effective in reducing mortality rates. The visual inspection of the oral cavity and pharynx, with the addition of flexible endoscopy and, possibly, blue-toluidine staining, can be

BACKGROUND The influence of tobacco smoke has been investigated on the growth rate and histology of prostate cancer, both in untreated tumors and in those subjected to fractionated irradiation. METHODS Twenty-five rats were implanted bilaterally with Dunning R3327 tumor fragments at 10 weeks of age.

The incidence of oral cancer appears to be increasing, especially in younger patients. Risk factors include use of tobacco and alcohol, and exposure to human papillomavirus. ViziLite Plus (Zila Pharmaceuticals) is a combination device that uses fluorescent light and toluidine blue tissue staining to

N,N-dimethyl-p-toluidine was nominated for toxicology and carcinogenesis studies by the National Cancer Institute based on the potential for human exposure through its use in dental materials and bone cements and the lack of toxicity and carcinogenicity data. Male and female F344/N rats and B6C3F1/N

This study examined whether enamel matrix derivative (EMD) inhibits the adhesion of cancer cells to bone. A typical breast cancer cell line, MCF-7, was used. Conditioned human osteosarcoma cell (Saos-2) medium was used as extracellular bone matrix (ECBM) to measure cell attachment. MCF-7 cells were

BACKGROUND In April 1991, an excess of bladder cancer cases among workers employed at a chemical manufacturing facility in Niagara Falls, NY, was reported. This excess was primarily confined to 708 workers who had ever been employed in the rubber chemicals manufacturing area of the plant, where the

In an historical mortality study, conducted on a cohort of 335 male employees in 4-chloro-o-toluidine (4-COT) production and processing plants, no deaths due to cancer of the urinary bladder had been identified. However, after completion of this study, urothelial carcinomas were recorded in eight of

Morphologic and histochemical characteristics were noted for three spontaneous tumors with eosinophilic cytoplasmic granules that occurred in aged Fischer 344 rats. Macroscopic lesions were widely distributed in the body, mainly involving the intra-abdominal adipose tissue, pancreas, and
