Carboxymethyl cellulose (CMC) is a polysaccharide which is widely used in many industrial sectors including food, textiles, paper, adhesives, paints, pharmaceutics, cosmetics and mineral processing. It is a natural organic polymer that is non-toxic and biodegradable. These properties make it ideal for industrial applications. However, a general lack of understanding of the interaction mechanism...

, talc not only causes a greater degree of apoptosis of lung cancer cells than bleomycin at equivalent concentrations, but it also demonstrates selectivity of action by sparing the normal mesothelium, which is not observed with bleomycin or doxycyline. Our in vitro observation was further supported by the discovery of a preserved layer of mesothelial cells despite an intense inflammatory pleura...

We read with interest the well researched article of Stefani et al. [1] about the different techniques of intrapleural talc. This technical paper really filled the gap in our knowledge following established evidences of superiority of the talc itself [2,3] over other products. We have a question and two comments. Could we be provided with data on the size of the talc particles? This intriguing ...

STUDY OBJECTIVE To demonstrate the efficacy, safety, and appropriate mode of instillation of talc for sclerosis in treatment of malignant pleural effusions (MPEs). DESIGN A prospective, randomized trial was designed to compare thoracoscopy with talc insufflation (TTI) to thoracostomy and talc slurry (TS) for patients with documented MPE. MEASUREMENTS The primary end point was 30-day freedom...

BACKGROUND Talc pleurodesis is widely performed for the management of persistent pneumothorax or pleural effusion, particularly malignant effusions. However, there are very few data characterizing fluorodeoxyglucose (FDG)-positron emission tomography (PET) and CT findings after treatment. METHODS We retrospectively evaluated the FDG-PET and CT studies of nine patients who underwent talc pleur...

Talc is a whitish raw material of mineral origin

Interstratifications of talc and trioctahedral smectites from different provenances are used as indicators for geological environments and for geotechnical and technical applications. However, comprehensive layer characterization of these interstratifications is rare. Sample EX M 1694, a clay with red-beige appearance from the Madrid basin was studied by X-ray diffraction analysis, X-ray fluore...

Talc powder and soapstone may contain asbestos. Random samples taken in the course of the past ten years from materials in use in Germany revealed only low asbestos contents. The present paper is based on analyses of bulk sample carried out by the German Berufsgenossenschaften as part of their prevention activities. In about one quarter of the 57 talc powder samples and 35 soapstone samples ana...

Peritoneal adhesions are challenging in abdominal surgery. In spite of different kinds of treatments still no definitive and effective treatment is suggested. To determine the prevention effects of intraperitoneal (ip) methylene blue in post surgical adhesion formation 44 rabbits were randomly divided in two groups of equal number. Group I received an intra peritoneal injection of a 1% suspensi...
