1. O direito à prevenção da Aids em tempos de retrocesso: religiosidade e sexualidade na escola
Esse artigo discute os desafios da prevenção em tempos de crescimento de casos de Aids entre jovens. Opiniões e práticas de estudantes no ensino médio, coletadas em pesquisa realizada de 2013-2017, indicaram que estavam incorporando o discurso preventivo e que a religiosidade tem efeito em crenças e valores antes da iniciação sexual, mas pode interfe

2. MananoligossacarÃdeo durante a reversÃo sexual de tilÃpia do nilo / Mannanoligosaccharide during the sexual reversion for nile tilapia
This present study aimed to evaluate the use of prebiotic mannanoligosaccharide (Bio-MosÂ) during the sexual reversion to larvae of Nile tilapia. The study was realized in the Laboratory of Aquaculture of the Western Parana State University (Unioeste). Onethousand nd eighty larvae of Nile tilapia with three days old and initial average weight of 10.9 Â 1.2

3. Immunostimulant effect of sulfated polysaccharides from the red marine alga Gracilaria caudata in sexual reversion of Nile tilapia, Oreochromis niloticus (LINNAEUS, 1766) under adverse conditions. / EFEITO IMUNOESTIMULANTE DOS POLISSACARÍDEOS SULFATADOS DA ALGA MARINHA VERMELHA Gracilaria caudata NA REVERSÃO SEXUAL DE TILÁPIA DO NILO, Oreochromis niloticus (LINNAEUS, 1766) EM CONDIÇÕES ADVERSAS.
Machos de tilápia chegam a crescer de 1,8 a 2,5 vezes mais rápido do que as fêmeas, sob condições de cultivo intensivo. Assim, as estratégias para obter populações monossexo estão focadas na produção de lotes de alevinos machos. A produção de indivíduos 100% machos através do uso do andrógeno 17-α-metiltestosterona é considerada a técn

4. A Gene, ALCA, Affecting the Life Cycle Form Expressed in PHYSARUM POLYCEPHALUM
The usual sequence of forms in the Physarum polycephalum life cycle is plasmodium–spore–amoeba–plasmodium. So-called "amoebaless life cycle" or alc mutants of this Myxomycete undergo a simplified plasmodium–spore–plasmodium life cycle. We have analyzed three independently isolated alc mutants and found in each case that the failure of the spores to

5. Role of metabolism of the mating pheromone in sexual differentiation of the heterobasidiomycete Rhodosporidium toruloides.
A trypsin-type endopeptidase (Kamiya et al., Biochem. Biophys. Res. Commun. 94:855-860, 1980) responsible for the metabolism of rhodotorucine A, the farnesyl undecapeptide mating pheromone secreted by mating type A cells of Rhodosporidium toruloides, was biologically characterized. Metabolic activity was found to be present exclusively on the cell surface of

6. Reversion of Aberrant Plants Transformed with Agrobacterium rhizogenes Is Associated with the Transcriptional Inactivation of the TL-DNA Genes 1
Transgenic plants harboring the left transfer DNA (TL-DNA) of the root inducing plasmid of Agrobacterium rhizogenes show many developmental abnormalities. We observed frequent appearance of normal looking lateral (revertant) shoots from such aberrant plants. Unlike aberrant shoots of the plant, revertant shoots exhibited a very high growth rate and set viabl

7. Genetics of an Unstable White Mutant in Drosophila Simulans: Reversion, Suppression and Somatic Instability
A spontaneous white mutation, white-milky (w(mky)) of Drosophila simulans is moderately unstable and is associated with a 16-kb long DNA insertion into the white gene. w(mky), which is an unstable mutation found in D. simulans, has been genetically analyzed. Among nine spontaneous, partial reversions toward wild type, five were white locus mutations. They ar

8. Individual Contributions of Mutant Protease and Reverse Transcriptase to Viral Infectivity, Replication, and Protein Maturation of Antiretroviral Drug-Resistant Human Immunodeficiency Virus Type 1
Human immunodeficiency virus type 1 (HIV-1) variants resistant to protease (PR) and reverse transcriptase (RT) inhibitors may display impaired infectivity and replication capacity. The individual contributions of mutated HIV-1 PR and RT to infectivity, replication, RT activity, and protein maturation (herein referred to as “fitness”) in recombinant virus
