2. Protein Removal from Natural Rubber Latex with Fe3O4@Al2O3 Nanoparticle
The presence of protein in the natural rubber latex for the medical device manufacture seems to be the most considered compound due to its allergic effect. Magnetic coated alumina (Fe3O4@Al2O3) has been known as an adsorbent for organic substrates due to its performance through physical and/or chemical interaction. In the current study, we tried to figure ou

3. Healing effects of natural latex serum 1% from Hevea brasiliensis in an experimental skin abrasion wound model,
Abstract Background Dermabrasion is related with mechanical and surgical traumas on the skin; usually topical antiseptics and/or saline have been used for healing. Natural products for wound healing can also be used for abrasions, such as latex from Hevea brasiliensis. Objective This study aimed to evaluate the in vitro viability and migratory/proliferativ

4. Development of a natural molluscicide prototype kit (MoluSchall) for the control of schistosomiasis mansoni transmission
Abstract INTRODUCTION In Brazil, Biomphalaria glabrata, B. tenagophila, and B. straminea are intermediate hosts of Schistosoma mansoni, the etiological agent of schistosomiasis mansoni. Molluscicide use is recommended by the WHO for controlling the transmission of this parasite. Euphorbia milii latex has shown promising results as an alternative molluscici

5. Cellulose Nanocrystals and Jute Fiber-reinforced Natural Rubber Composites: Cure Characteristics and Mechanical Properties
A comparative study was conducted for three natural rubber (NR) composites: one containing raw jute fibers, one containing bleached jute fibers, and one containing cellulose nanocrystals (CNCs). The composites were prepared by adding each filler at 5 or 10 phr to the latex before chemical coagulation, and the composites were processed in a two-roll mixing mi

6. Mururé (Brosimum acutifolium Huber) in the treatment of syphilis in colonial Amazonia: historical data to the actual contribution to treatment
ABSTRACT Historical ethnobotanical studies of medicinal plants reveal important information about traditional practices of human groups and influence current understanding of the use of plants. The present article describes the ethnopharmacology of mururé (Brosimum acutifolium) since the XVIII century for the treatment of syphilis and correlates past and pr

7. Synthesis and characterization of isoprene oligomers to compare different production chemical processes
Abstract Three methods to obtain isoprene oligomers were evaluated: chemical degradation of non-vulcanized coagulated natural rubber; chemical degradation of natural rubber latex; and oligomerization of the isoprene monomer. The products were characterized by infrared spectrometry (FTIR), nuclear magnetic resonance (NMR) and size-exclusion chromatography (S

8. Compósito cimentício com elevado teor de fibra de coco tratada: propriedades físicas e durabilidade
RESUMO O aproveitamento da fibra de coco na construção civil pode diminuir o consumo de agregados minerais como areia e brita, e melhorar propriedades físicas e mecânicas de um compósito cimentício. No entanto, um dos pontos mais precários está relacionado à degradação acelerada da fibra vegetal pela ação química da matriz cimentícia. Então,

9. Rubber gloves biodegradation by a consortium, mixed culture and pure culture isolated from soil samples
Abstract An increasing production of natural rubber (NR) products has led to major challenges in waste management. In this study, the degradation of rubber latex gloves in a mineral salt medium (MSM) using a bacterial consortium, a mixed culture of the selected bacteria and a pure culture were studied. The highest 18% weight loss of the rubber gloves were de

10. Membrana de látex natural de Hevea brasiliensis auxilia no processo de reparação tecidual em bovinos
RESUMO Feridas cutâneas em bovinos são um constante desafio clínico cirúrgico por desencadearem perdas econômicas bastante significativas. O látex proveniente da seiva da seringueira (Hevea brasiliensis) apresenta potencial terapêutico para incrementar o processo de reparação tecidual. Portanto, pretendeu-se com esse estudo avaliar o tipo de reaçã

11. ESTIMULAÇÃO DA PRODUÇÃO DE LÁTEX EM SERINGUEIRA (Hevea brasiliensis L.) COM DOSES DE ETHREL
RESUMO O emprego do estimulante Ethrel® na cultura da seringueira tornou-se essencial para garantir maiores produções de borracha. Ao ser aplicado no local do corte da árvore, esse estimulante libera o gás etileno que provoca o aumento do período de exsudação do fluxo do látex. As diluições e aplicações devem ser realizadas de forma correta para

12. Natural membranes of Hevea brasiliensis latex as delivery system for Casearia sylvestris leaf components
ABSTRACT Natural latex from Hevea brasiliensis (Wild. ex A.Juss) Müll.Arg., Euphorbiaceae, showed angiogenic action and Casearia sylvestris Sw., Salicaceae, leaf derivatives presented anti-inflammatory and wound healing activities. Therefore, an association of these effects was interesting for wound healing applications. The aims of this study were the deve
