Chitosan is a biopolymer that is being increasingly used in distinct areas such as pharmaceutical, biomedical, cosmetics, food industry and agriculture. Among the interesting biological activities that have been ascribed to chitosan, the antimicrobial activity is probably the one that generates the higher number of applications. Considering that feet present favorable conditions for microorgani...

Tannery workers are at potential exposure to detrimental agents rendering them vulnerable to respiratory and dermal problems. Thus by performing pulmonary functions among leather tannery workers, we can decipher the effect of chromium and leather dust on lung functions and also the decline of respiratory functions with increasing years of exposure to leather dust. Pulmonary functions were asses...

The leather bass Dermatolepis dermatolepis (Boulenger, 1895) is a poorly known grouper living on coral and rocky reefs in the eastern Pacific Ocean. One of only three species in the genus Dermatolepis (family Serranidae, subfamily Epinephelinae), the leather bass distribution ranges from southern California to Ecuador, including the Gulf of California, the Galapagos Islands and other offshore i...

AIM the aim of this study is to measure acceptance of a specific functional food: apple (fruit) leather, based on organoleptic characteristics and to identify consumer types and preferences for natural additives which increase the product's functionality and meet current nutritional needs. MATERIALS AND METHODS a sample of 800 consumers provided an evaluation of apple leather in terms of acce...

BACKGROUND Approximately 1-3% of the adult population in Europe is allergic to chromium (Cr). A new restriction in REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) based on the ISO 17075 standard has recently been adopted in the EU to limit Cr(VI) in consumer and occupational leather products. OBJECTIVES The aim of this study was to critically assess key experiment...

THE problem of perspiration and its removal from the amputee's arm and leg stumps encased in sockets has engaged the attention of the doctor and limb fitter for as long as limbs have been fitted. In the early days of leather prostheses, a few months of wear during the summer were sufficient to cause the leather to rot and degrade because of perspiration. Since it was not possible to wash leathe...

Sometimes, commercial products obtained from wild animals are sold as if they were from domestic animals and vice versa. At this point of the productive chain, legal control of possible wildlife products is difficult. Common in the commerce of northern Argentina, skins of two wild species, the carpincho and the collared peccary, look very similar to each other and to those of the domestic ...

Chromium is a transition metal and has been shown to elicit contact dermatitis. Although leather products have been known to be the most significant source of chromium exposure these days, the majority of reports have been related to exposure from shoe products. We herein report a professional golfer who became allergic to golf gloves made of chromium-tanned leather. A 27-year-old woman golfer ...

Disposal of chrome tanned leather waste (CTLW) generated in leather processing industries has many environmental implications. This paper presents a double pyrolysis (PI & PII) method to dispose hazardous chrome tanned leather solid waste by converting it into useful products. When CTLW was subjected to double pyrolysis, three major products obtained were; (i) an energy enriched combustible gas...

Solid state ¹³C-NMR spectra of pure tannin powders from four different sources--mimosa, quebracho, chestnut and tara--are readily distinguishable from each other, both in pure commercial powder form, and in leather which they have been used to tan. Groups of signals indicative of the source, and type (condensed vs. hydrolyzable) of tannin used in the manufacture are well resolved in the spectra...
