Background. Combination antiretroviral therapy (cART) reduces genital tract human immunodeficiency virus type 1 (HIV-1) load and the risk of sexual transmission, but little is known about efficacy cART for decreasing viral (GTVL) differences in sex or HIV-1 subtype.
Water erosion is one of the main environmental impacts land use. When soil and water losses occur, nutrients essential for growth maintenance plants are removed, with harmful outcomes on sustainability agriculture environment. In addition, they lead to other deleterious effects, such as sedimentation eutrophication bodies. Estimation due in sub-basins prediction degradation, especially areas semi-intensive cultivation, coffee fields. Thus, aim this study was estimate relation limit loss...
Some macrophytes species show a high growth potential, colonizing large areas on aquatic environments. Cattail (Typha angustifolia L.) uncontrolled causes several problems to human activities and local biodiversity, but this also may lead competition further for itself. Thus, the objective of study was investigate anatomical modifications T. plants from different population densities, once it can help understand its biology. Roots leaves were collected natural populations growing under low...
The tissue culture can contribute to the propagation of several economic species, such as bromeliads. This research aimed at evaluating auxins type and concentration in vitro ex rhizogenesis Neoregelia concentrica bromeliad. N. shoots were induced a growth medium with 15.0 µM 6-benzylaminopurine, for 80 days, followed by sub-cultivation phytoregulator-free medium, 45 days. In rhizogenesis, grew supplemented indole-3-butyric acid (IBA) or naphthalene-acetic (NAA), concentrations 0.0 µM, 1.0...
Sewage sludge is the solid residue obtained from urban sewage treatment plants. It possible to use in a sustainable way as fertilizer and soil conditioner due its high levels of organic matter nutrients. Besides pathogens volatile compounds, may also contain heavy metals which accumulate contaminate crops food chain. The aim this study was evaluates changes fertility dystrophic Red Latosol availability following application sludge. assessed whether supplied large amounts would decrease...
A cagaiteira é uma espécie nativa do Cerrado com elevado potencial frutífero. Como suas sementes apresentam elevada variabilidade, sendo ainda recalcitrantes e dormentes, a germinação in vitro apresenta-se como alternativa para propagação da espécie, além de permitir obtenção explantes juvenis micropropagação. Com presente trabalho, objetivou-se avaliar o efeito escarificação luminosidade na cagaiteira. Sementes desprovidas tegumento intactas foram inoculadas em meio MS mantidas ausência...
Eucalyptus stands in the setting of worldwide forestry due to its adaptability, rapid growth, production high-quality and low cost wood pulp fibers. The eucalyptus convetional breeding is impaired mainlly by long life cycle making genetic transformation systems an important tool for this purpose. However, system requires vitro eficient protocols plant induction, regeneration seletion, that allow obtain transgenic plants from transformed cell groups. aim work was evaluate callus formation...
The plant micro-propagation in bioreactor systems is regarded as one way to reduce cost by automation and production scheduling. This research was carried out order obtain an efficient procedure for clone of Eucalyptus camaldulensis on different types including continuous temporary immersion bioreactor. To do so, the apical meristems (1 mm) with adjacent tissue (2,5 were used initial explants. These tissues cultured, 60 days, semisolid culture medium supplemented 1 mg L-1 indole acetic acid...
Environmental sciences play a central role in wide array of fronts, encompassing research and innovation areas that include natural resource management, environmental impact assessment, biodiversity conservation, adoption precision agriculture practices, effective agricultural waste adaptation to climate change. Furthermore, these are pivotal promoting education, aiming disseminate sustainable practices effectively. Given the collaboration among different experts, sciences, due their...
Por apresentar dormência em suas sementes, a propagação do pequizeiro necessita de estudos para obtenção mudas por via assexuada. Este trabalho teve como objetivo contribuir o estabelecimento um protocolo micropropagação pequizeiro. Para indução brotações, os explantes foram inoculados meio WPM com diferentes concentrações BAP e ANA. raízes, brotações obtidas in vitro transferidas suplementado AIB na presença ou ausência carvão ativado. As plantas sacos polietileno contendo substrato,...
This work was carried out to characterise morphologically and ultrastructurally the banana callus, obtained from scalp method. Genotypes of banana, cv. Prata anã, cultivated in vitro were used induce meristems at leaf base; subsequently, structures known as scalps formed. For ultrastructural analysis, five samples callus collected, fixed Karnovsky solution analysed by scanning electron microscope (SEM) transmission (TEM). The formation three types observed: Type 1 - transparent watery 2...
The objective of this work was to elucidate the growth curve Eucalyptus camaldulensis Dehn. calli analyzing their anatomical modifications. A sigmoid aspect fresh matter observed, with five different phases (lag, exponential, linear, deceleration and decline). In lag phase, highest percentage 87%, which reduced during evaluation period 17% in linear phase. As for analyses, cellular multiplications observed exponential increase cell size promoting volume establishment globular conformation.
Este estudo objetivou avaliar a influência das citocininas durante o estágio de multiplicação in vitro e combinação entre carvão ativado com ácido indol-3-butírico (AIB) enraizamento Handroanthus impetiginosus. Para vitro, os segmentos nodais dos brotos obtidos partir do estabelecimento plântulas foram inoculados em meio cultura Woody Plant Medium (WPM), sem as seguintes concentrações 6-benzilaminopurina (BAP), cinetina (KIN) tidiazuron (TDZ): 0,5; 1,0; 2,0; 4,0 8,0 µmol L-1.

O pequizeiro é uma frutífera nativa dos cerrados brasileiros com grande potencial econômico. Neste trabalho, objetivouse avaliar o efeito de substâncias potencialmente estimuladoras da germinação. As sementes foram extraídas caroços e colocadas para germinar em rolos papel embebidos as seguintes soluções: água destilada (Controle); 2mmol L-1 KNO3 (Nitrato); Etephon (ET); 1mmol GA3 (GA); + (GA ET). Os resultados percentagem germinação tempo médio foram, respectivamente, 54,0% 9,3 dias no...
Garcinia brasiliensis, popularly known as Bacupari, is native to the Amazon and commonly used in folk medicine for its therapeutic properties. This plant rich bioactive compounds like benzophenones. However, there are no works about vitro establishment achievement of secondary metabolites this plant. Thus, aim work was determine growth curve perform biochemical phytochemical analyses calli obtained from procambium segments Bacupari. The followed a sigmoidal pattern, with four distinct phases...
The procedures described by Draize have been criticized for ethical reasons.Thus, a comparative study was performed between ocular and cutaneous irritation tests, using rabbits in vitro test through agar diffusion with the use of NCTC clone 929, FPC-IAL SIRC cell lines.The results obtained revealed that positive samples, which presented up to degree 3 reactivity rate, according USP 31, did not provoke or irritation.The samples grade 4 also showed different degrees irritation, exception two...
