“…2). [33] In a field trial in Southern Mississippi following a single integrated insecticide and SIT application, the boll weevil population in the eradication zone was suppressed below detectable levels in 203 out of 246 fields, [3] with an estimated chemical release of 100 ng busulfan/weevil or 6 mg per square mile.

Both historically and at present, vector control is the most generally effective means of controlling malaria transmission. Insecticides are the predominant method of vector control, but the sterile insect technique (SIT) is a complementary strategy with a successful track record in both agricultural and public health sectors. Strategies of genetic and radiation-induced sterilization of Anopheles have to date been limited by logistical and/or regulatory hurdles. A safe and effective mosquito chemosterilant would therefore be of major utility to future deployment of SIT for malaria control. Here we review the prior and current use of chemosterilants in SIT, and assess the potential for future research. Recent genomic and proteomic studies reveal opportunities for specific targeting of seminal fluid proteins, and the capacity to interfere with sperm motility and storage in the female.

“…Desta forma, a atividade da enzima Catalase pode ser medida através da avaliação do consumo de peróxido de hidrogênio. Este teste consiste em avaliar a diminuição da absorbância no comprimento de onda, onde há a maior absorção pelo peróxido de hidrogênio, utilizando-se cubetas de quartzo devido à alta energia do comprimento de onda no qual foram realizadas as medidas (nelson & Kiesov, 1972).…”

A infertilidade masculina é causada por diferentes fatores. As causas mais comuns incluem número insuficiente de espermatozóides, e/ou pouca motilidade destes. O uso de antioxidantes poderia contribuir no tratamento da infertilidade masculina em pacientes com perda da qualidade seminal. O objetivo deste estudo foi avaliar se o uso de antioxidantes (Spirulina platensis e resveratrol) contribui na qualidade seminal em homens entre 40 e 60 anos de idade. material e métodos: Este é um estudo clínico randomizado com dois grupos: Spirulina platensis (Sp) e Resveratrol (R), cada um dos grupos foi composto por 25 homens entre 40 a 60 anos de idade, totalizando 50 homens. Para as análises, o grupo Sp foi submetido à terapia de 4g de Spirulina platensis em cápsulas e o grupo R foi submetidos à terapia com 500mg de Resveratrol em cápsulas, ambos durante 90 dias. As amostras foram submetidas às análises de Espermograma, Índice de substâncias reativas ao ácido 2-tiobarbitúrico (TBARS) e Catalase (CAT), antes e depois da terapia. Todos os homens foram submetidos a um questionário padrão. A análise de espermograma obteve significância na concentração (p=0,022) e morfologia espermática (p=0,037) com o uso de Sp, e significância na motilidade (p=0,027) e vitalidade (p=0,017) com uso de R. Conclusão: a terapia de 90 dias com Spirulina platensis ou resveratrol tem um efeito estacionário das espécies reativas de oxigênio, contribuindo para a melhora da qualidade seminal em homens entre 40 e 60 anos de idade. Palavras chave: Antioxidantes. Envelhecimento. Infertilidade masculina. Qualidade seminal.

The dirnethanesulfonate esters of polymethylene glycols undergo three types of doublegroup transfer reactions as a result of electron-impact mass spectrometry: 1. Transfer of a hydrogen and one methanesulfonate group to the second methanesulfonate with cleavage to yield a protonated methanesulfonic acid anhydride. 2. Transfer of two hydrogens to a methanesulfonate group with cleavage to yield a protonated methanesulfonic acid. 3. Transfer of a hydrogen and a methyl group to the second methanesulfonate with cleavage to yield a protonated methyl methanesulfonate. Bicyclic transition states are proposed for these reactions.
