1. Relationship between meiotic instability and fertility in F2 generation Arabusta coffee plants
ABSTRACT Parental plants, an F1 interspecific hybrid and the F2 generation from Arabusta coffee plants were investigated for meiotic behavior and viability of pollen to understand part of their reproductive biology that affects their possible use in coffee breeding programs. Both parental plants (C. canephora var. Robusta 4x and C. arabica var. dihaploid Bou

2. Alterations in Biomarkers Associated with Sterility in Pectinophora gossypiella (Saunders) Induced by Gamma Irradiation
ABSTRACT Nowadays, radiation technology is widely used to produce changes in Biosystems. The goal of this work is to determine the variation induced male Pectinophora gossypiella in gamma-irradiated as pupae using 50Gy and 150Gy. Comparing elements composition and DNA (using RAPD-PCR) between substerile 50Gy and the sterile dose 150Gy in P. gossypiella showe

4. Adding guarana powder to medfly diets: an alternative for improving the Sterile Insect Technique
ABSTRACT Ceratitis capitata (medfly) is a globally important horticultural pest that can be controlled using the sterile insect technique (SIT), but the success of SIT depends on the sexual performance of mass-reared males when released into the field. We added “guarana” (Paullinia cupana) powder (derived from an Amazonian fruit that is considered to be

5. The effects of supplemental melatonin administration on the healing of bone defects in streptozotocin-induced diabetic rats
ABSTRACT Diabetes mellitus (DM) causes an increased production of free radicals that can impair bone healing. Melatonin is a hormone secreted mainly by the pineal gland, which participates in the neutralization process of free radicals. Objective The aim of this study was to investigate histologic and biochemical effects of supplemental melatonin administr

6. Effect of low-level laser therapy (GaAlAs - λ660 nm) on muscle function
Introduction:Low-level laser therapy (LLLT) is effective in preventing fatigue and in stimulating the microcirculation and cellular activity. In this study, we examined the effect of LLLT on injured tibial muscle in vivo by assessing muscle function during fatigue.MethodsTwenty-four male mice were used. Each mouse received an injection of sterile 0.9% saline

7. Successful crosses between fungal-resistant wild species of Arachis (section Arachis) and Arachis hypogaea
Peanut (Arachis hypogaea) is the fifth most produced oil crop worldwide. Besides lack of water, fungal diseases are the most limiting factors for the crop. Several species of Arachis are resistant to certain pests and diseases. This study aimed to successfully cross the A-genome with B-K-A genome wild species previously selected for fungal disease resistance

8. Large indoor cage study of the suppression of stable Aedes aegypti populations by the release of thiotepa-sterilised males
The sterile insect technique (SIT) is a promising pest control method in terms of efficacy and environmental compatibility. In this study, we determined the efficacy of thiotepa-sterilised males in reducing the target Aedes aegypti populations. Treated male pupae were released weekly into large laboratory cages at a constant ratio of either 5:1 or 2:1 steril

9. Phenotypic, cytogenetic and spike fertility characterization of a population of male-sterile triticale
Triticale (X Triticosecale Wittmack) is a good cereal for production of flour and feed. A segregating population of triticale was developed from a male-sterile (MS) plant. To determine whether this new source of male sterility in triticale is appropriate for use in breeding programs the expression of the male sterility phenotype was characterized through spi

10. Isolation and characterization of CaMF3, an anther-specific gene in Capsicum annuum L.
Previous work on gene expression analysis based on RNA sequencing identified a variety of differentially expressed cDNA fragments in the genic male sterile-fertile line 114AB of Capsicum annuum L. In this work, we examined the accumulation of one of the transcript-derived fragments (TDFs), CaMF3 (male fertile 3), in the flower buds of a fertile line. The ful

11. Determinação da dose de radiação gama esterilizante pela avaliação dos parâmetros biológicos de machos de Ceratitis capitata (Diptera: Tephritidae), linhagem tsl - Vienna 8 / Determination of the dose of gamma radiation sterilization for assessment of biological parameters of male Ceratitis capitata (Diptera: Tephritidae), tsl - Vienna 8 strain
A linhagem tsl (temperature sensitive lethal) - Vienna 8 da espécie Ceratitis capitata, por apresentar mutações que facilitam a criação e a liberação de apenas machos estéreis no campo, vem sendo utilizada em programas de controle da mosca-do-mediterrâneo com o uso da técnica do inseto estéril. O objetivo deste trabalho foi determinar a dose de ra

12. Prevalence of pneumococcal serotypes and resistance to antimicrobial agents in patients with meningitis: ten-year analysis
OBJECTIVES: To determine the prevalence of pneumococcal serotypes and antimicrobial susceptibility in patients with meningitis, and to evaluate the implications for vaccine coverage. METHODS: Pneumococcal strains obtained from normally sterile fluids from patients admitted with meningitis were isolated at the Hospital de Clínicas of the Universidade Federal
