Hancornia speciosa serum latex fraction: a non-allergenic biomaterial

Braz. j. biol; 83 (), 2023
Abstract Plant-derived products can assist in the healing process of dermal wounds. It has been demonstrated that Hancornia speciosa latex present angiogenic, osteogenic, anti-inflammatory, and antioxidant activities. Then, it could contribute to the wound healing process. However, natural products in co...

Evaluation of microsatellite allelic patterns to DNA fingerprinting in rubber tree clones

Biosci. j. (Online); 38 (), 2022
The rubber tree (Hevea brasiliensis) is native to the Amazon region, and it is widely exploited due to natural rubber produced from latex. There are many clonal varieties, without certification tests. In order to determine a genetic certification, 15 clones were genotyped to identify their genetic patter...

Influence of spatial variability of soil chemical attributes on the nutritional status and growth of the rubber tree

Biosci. j. (Online); 38 (), 2022
The productive potential of the rubber tree (Hevea brasiliensis) is dependent on its genetic composition, in addition to edaphoclimatic factors and management practices. However, as soil properties are not homogenous, knowing the spatial variability of soil attributes would be important to increase produ...

Atmospheric evaporative demand and water deficit on the ecophysiology of Rubber seedlings

Biosci. j. (Online); 38 (), 2022
The search for genetic materials resistant to adverse weather conditions has been a major focus in studies on species of economic interest. The objective of the present study was to assess the growth and photosynthesis of rubber seedlings clones under two conditions of atmospheric evaporative demand, cha...

Zinc - rooting cofactor in rubber tree mini-cuttings

Biosci. j. (Online); 36 (6), 2020
The rubber tree (Hevea brasiliensis Müell. Arg.) is a species of significant economic interest in the natural rubber industry in Brazil and the world. This species presents recalcitrance to rooting, and its cuttings are difficult to propagate. This study aimed to evaluate the effect of the pre-condition...

Healing effects of natural latex serum 1% from Hevea brasiliensis in an experimental skin abrasion wound model

An. bras. dermatol; 95 (4), 2020
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 eva...

Cicatrização de feridas cutâneas: uso da membrana de látex natural isolada e associada à fibrina rica em plaquetas em ratos Wistar

Devido à alta incidência de feridas e lesões de pele, a busca científica tem se focado no desenvolvimento de coberturas e substitutos epidérmicos alternativos às técnicas de enxertia que possuam a mesma função de evitar a exposição de feridas às variações externas. O látex natural derivado...

Bark beetles in a mixed plantation of bertholletia excelsa and hevea brasiliensis in the southern Amazon

Biosci. j. (Online); 35 (3), 2019
Bark beetles (Curculionidae: Scolytinae) are wood borers with the potential to cause significant damage in forest plantations. Studies of this group are more common in plantations of Eucalyptus, and Pinus, but the increase of planting with other forest species, such as Brazil nut and rubber t...

Epidemiologia da leishmaniose tegumentar americana (LTA) no município de Xapuri, Estado do Acre, Brasil: estudo em população humana, cães domésticos e vetores

Introdução. A leishmaniose tegumentar americana (LTA) é uma endemia de importância em saúde pública na Amazônia Brasileira, onde possui diferentes perfis de transmissão com a participação de diversas espécies de vetores e de protozoários do gênero Leishmania. O Estado do Acre apresenta altos...
