Background Rubber tree [Hevea Braziliensis (Willd. ex Adr. de Juss.) Muell-Arg.], a native species of the Amazon Rainforest in South America, belonging to the Euphorbiaceae family, is world’s major source of natural latex. Brazil, despite being the center of origin and diversity of the species and latex main producer at the end of XIX century, nowadays imports around 70% of the rubber consumed ...

Rubber tree (Heveabrasiliensis) is the only commercially cultivated plant for producing natural rubber, one of the most essential industrial raw materials. Knowledge of the evolutionary and functional characteristics of kinases in H. brasiliensis is limited because of the long growth period and lack of well annotated genome information. Here, we reported mitogen-activated protein kinases in H.b...

Background Latex-fruit syndrome (LFS), defined as hypersensitivity to particular fresh fruits (Wagner S. & Breiteneder H. Bioch Soc Trans, 2002), has been described in 30-50% of pts affected from natural rubber latex (NRL) allergy and it is due to IgE Abs that cross-react with similar epitopes on phylogenetically related proteins. Objective: To estimate the prevalence of LFS in a group of NRL a...

©FSRH J Fam Plann Reprod Health Care 2008: 34(2) Background Itching following contact with latex condoms is a familiar problem in contraceptive services, and popular textbooks still maintain that it is frequently an excuse for avoiding condoms, or that spermicide is to blame.1 If a patient experiences symptoms on contact with other latex items as well as condoms then it would be reasonable to s...

BACKGROUND Dental practitioners, like other health care providers who regularly use latex gloves, are at increased risk for latex sensitivity. They are also at risk for irritant or allergic contact dermatitis. OBJECTIVE This study was carried out to determine the prevalence of latex sensitivity and possible risk factors in staff and students of a Faculty of Dentistry. METHODS A cross-sectio...

The aim of this study is to investigate the effect of particles as filler in soft rubber sensors installed in artificial skin. We examine sensors made of natural rubber (NR-latex) that include magnetic particles of Ni and Fe₃O₄ using magnetic compound fluid (MCF). The 1-mm thickness of the electrolytically polymerized MCF rubber makes production of comparatively thin rubber sensors feasible. We...
