1. Estudo experimental sobre a ação de larvicidas em populações de Aedes aegypti do município de Itabuna, Bahia, em condições simuladas de campo
Resumo Objetivo: avaliar, em condições simuladas de campo, a eficácia do pyriproxyfen (hormônio juvenil), do novaluron (inibidor de quitina) e do spinosad (biolarvicida) no controle do Aedes aegypti. Métodos: exposição periódica de larvas de Ae. aeypti obtidas em Itabuna a recipientes tratados com os larvicidas, e comparação do efeito residual

2. Efeitos do uso do hormônio de crescimento em crianças e adolescentes com artrite idiopática juvenil: revisão sistemática
Resumo Introdução: Crianças com artrite idiopática juvenil (AIJ) frequentemente apresentam prejuízo no crescimento e baixa estatura. Existem evidências de que o uso terapêutico do hormônio de crescimento (GH) é útil e seguro nesses pacientes. Objetivo: Analisar os efeitos do uso de GH em pacientes com AIJ. Método: Fez-se revisão sistemática d

3. Genome-wide comparison of genes involved in the biosynthesis, metabolism, and signaling of juvenile hormone between silkworm and other insects
Juvenile hormone (JH) contributes to the regulation of larval molting and metamorphosis in insects. Herein, we comprehensively identified 55 genes involved in JH biosynthesis, metabolism and signaling in the silkworm (Bombyx mori) as well as 35 in Drosophila melanogaster, 35 in Anopheles gambiae, 36 in Apis mellifera, 47 in Tribolium castaneum, and 44 in Dan

4. Insights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in sting

5. Expressão de genes da via de biossíntese do Hormônio Juvenil em Melipona scutellaris (Hymenoptera, Apidae, Meliponini)
Em abelhas sem ferrão do gênero Melipona, nas quais a diferenciação de castas não depende somente da quantidade e/ou qualidade do alimento larval, o Hormônio Juvenil (HJ) tem sido apresentado como agente responsável, juntamente com fatores ambientais, por mecanismos genéticos que promovem as diferenças casta específicas. Na via de biossíntese do H

6. Endocrinologia e controle da vitelogênese em carrapatos = Endocrinology and control of tick vitellogenesis / Endocrinology and control of tick vitellogenesis
Background: Ticks are distributed worldwide, with impacts on human and animal health. The cattle tick Rhipicephalus (Boophilus) microplus is the main parasite that affects livestock in tropical and subtropical regions of the world, causing large economical losses. Tick control methods are based on the application of chemical acaricides, which has resulted in

8. Decreased high-density lipoprotein cholesterol levels in polyarticular juvenile idiopathic arthritis
OBJECTIVES: To investigate the prevalence of dyslipoproteinemia in a homogeneous cohort of polyarticular juvenile idiopathic arthritis patients. METHODS: Based on the National Cholesterol Education Program, fasting lipoprotein levels and risk levels for coronary artery disease were determined in 28 patients with polyarticular juvenile idiopathic arthritis.

9. Residual effect of a micro-encapsulated formulation of organophosphates and piriproxifen on the mortality of deltamethrin resistant Triatoma infestans populations in rural houses of the Bolivian Chaco region
The Bolivian Chaco is part of the endemic region of Chagas disease and an area where pyrethroid resistant Triatoma infestans (Hemiptera: Reduviidae) populations has been reported. The World Health Organization identified these resistant populations as an important focus for research. The objective of this study was to evaluate the residual effect of a micro-

10. Nitric oxide contributes to learning and memory deficits observed in hypothyroid rats during neonatal and juvenile growth
INTRODUCTION: Severe cognitive impairment follows thyroid hormone deficiency during the neonatal period. The role of nitric oxide (NO) in learning and memory has been widely investigated. METHODS: This study aimed to investigate the effect of hypothyroidism during neonatal and juvenile periods on NO metabolites in the hippocampi of rats and on learning and m

11. Minor sperm abnormalities in young male post-pubertal patients with juvenile dermatomyositis
The objective of the present study was to identify sperm abnormalities in young male patients with juvenile dermatomyositis (JDM). In 2005, 18 male JDM patients, diagnosed according to the criteria of Bohan and Peter, were followed at the Pediatric Rheumatology Unit and Rheumatology Division, of our Institution. Of the 18 males, 11 were pre-pubertal and 7 we

12. Growth hormone-insuline-like growth factor-I system in pejerrey Odontesthes bonariensis (Atheriniformes)
Using biotechnology to increase the growth rates of fish is likely to reduce production costs per unit of food. Among vertebrates, fish appear to occupy a unique position, when growth patterns are considered. With few exceptions, fish species tend to grow indeterminately, implying that size is never fixed. Both hyperplasia and hypertrophy contribute to post-
