Hemp fibre reinforced natural rubber bio-macromolecule based biodegradable engineered leather.

Out of the diverse industrial applications of hemp fibre, for the first time we report the development of a leather alternative (flexible composite) material by integrating hemp fibre, as a bio-reinforcement and natural rubber (latex) macromolecules, as a matrix. For developing such unique product, primarily, hemp fibre was extracted from the Canabinus sativa L., i.

Hydrophobic functionalization of cellulosic substrate by tetrafluoroethane dielectric barrier discharge plasma at atmospheric pressure.

Hydrophobic functionalization of cellulosic fabric (viscose) was carried out using helium/tetrafluoroethane (He/TFE) plasma, a commercially available fluorocarbon gas, at the atmospheric pressure. By selecting suitable plasma parameters, He/TFE plasma was produced and maintained in glow state so that the various fragments of TFE in plasma zone could react covalently with the cellulose. After the plasma treatment, the highly hydrophilic cellulosic fabric turned into superhydrophobic fabric with a water absorbency time of >> 60 min, a water contact angle of 153° and a water rolling angle of 5°.

Acanthus ilicifolius plant extract prevents DNA alterations in a transplantable Ehrlich ascites carcinoma-bearing murine model.

Aim: To investigate the chemopreventive efficacy of the Indian medicinal plant Acanthus ilicifolius L Acanthaceae in a transplantable Ehrlich ascites carcinoma (EAC)-bearing murine model.

Methods: Male Swiss albino mice were divided into four groups: Group A was the untreated normal control; Group B was the EAC control mice group that received serial, intraperitoneal (ip) inoculations of rapidly proliferating 2 x 10(5) viable EAC cells in 0.2 mL of sterile phosphate buffered saline; Group C was the plant extract-treated group that received the aqueous leaf extract (ALE) of the plant at a dose of 2.

Protective role of fish oil (Maxepa) on early events of rat mammary carcinogenesis by modulation of DNA-protein crosslinks, cell proliferation and p53 expression.

Background: Fish oil is known to protect from many types of cancers of the colon, liver, breast, prostate and lung 123. The objective of the present study was to evaluate the role of fish oil [Maxepa, supplemented at a dose of 0.5 ml is equivalent to 90 mg eicosapentaenoic acid (EPA) and 60 mg docosahexaenoic acid (DHA)] on cell proliferation, expression of p53 tumor suppressor protein and DNA protein crosslinks (DPCs) in a defined model of chemical rat mammary carcinogenesis.

In vivo evaluation of antidiarrhoeal activity of Rhus semialata fruit extract in rats.

Rhus semialata Murr. (Anacardiaceae) is a deciduous tree of north eastern India. The fruit of this plant is traditionally used to control diarrhoea and dysentery.

Vanadium, a versatile biochemical effector in chemical rat mammary carcinogenesis.

Recent studies indicate the role of the micronutrient vanadium in chemoprevention in many animal models, human cancer cell lines, and also in xenografted human carcinomas of the lung, breast, and gastrointestinal tract. The present studies were undertaken to ascertain the antineoplastic potential of vanadium in a defined model of mammary carcinogenesis. Female Sprague-Dawley rats, at 50 days of age, were treated with 7,12-dimethylbenz(alpha) anthracene (DMBA) (0.
