1. Male fertility potential alteration in rheumatic diseases: a systematic review
ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial rel

2. Aspectos fisiológicos e da produção do arroz em resposta ao silício / Physiological and productive aspects of rice plants according to silicon supplying
The objective of this study was to analyze the role of supplemental silicon (Si) in the biomass accumulation and grain yield of rice (Oryza sativa L.). Different experiments were carried out in which wild rice plants (japonica subsp. Oochikara - WT) and mutant defective for the absorption of Si - lsi1 (Low silicon rice 1) were raised under hydroponics condit

3. Impacto do Taraxerol em combinação com o extrato da planta de Euphorbia tirucalli nos parâmetros biológicos da Lymnaea acuminata
O presente trabalho foi levado a efeito para avaliar a atividade moluscicida do ingrediente ativo Taraxerol junto com o extrato de acetona da Euphorbia tirucalli contra o caramujo Lymnaea acuminata. Foram estudados a fecundidade, o desenvolvimento e sobrevivência do caramujo Lymnaea acuminata exposto a estes extratos. Os efeitos danosos destes extratos test

4. Parametros reprodutivos masculinos e fertilidade de ratos adultos expostos ao inseticida fenvalerato / Male reproductive parameters and fertility of adult rats exposed to fenvalerate
Fenvalerate is a synthetic pyrethroid insecticide widely used in agriculture to control a variety of insects. Although it is considered to be of low acute toxicity to mammals, studies have showed that pyrethroids can have estrogenic activity and can act as endocrine disruptors, causing important reproductive impairment in males. It is documented in the liter

5. Distribuição espacial e temporal de espécies simpátricas de Leptodactylus do grupo fuscus em áreas naturais e antrópicas na região de Itirapina e Brotas, sudoeste do Brasil / Spatial and temporal distribution of sympatric species of Leptodactylus group fuscus in natural and anthropic areas in Itirapina and Brotas region, southeast of Brazil
Anuran species inhabiting open landscapes are usually habitat generalists, so it is considered more tolerant to disturbed habitat. Although, the effect of habitat degradation on these open habitat species have been poorly documented. The goal of this study was to observe the effects of habitat modification caused by human on spatial and temporal distribution

6. AvaliaÃÃo toxicolÃgica prÃ-clÃnica do Ãleo de Carapa guianensis Aublet.
Carapa guianensis (Meliaceae), a typical tree from amazon region, is popularly known as Andiroba. Its seed oil is used as anti-inflammatory, analgesic and insect repellent. Although C. guianensis is largely used by people, there are no studies concerning its toxicity. In this way, the aim of this work was to evaluate the safety of the C. guianensis seed oil

7. Morpho-functional characteristics of sex reversal in Synbranchidae (Teleostei: Synbranchiformes) / Perfil morfo-funcional da inversão de sexo em Synbranchidae (Teleostei: Synbranchiformes)
Teleost fishes exhibit several sexual patterns during their ontogeny, in which the gonads change into functional ovaries or testes. In distinct Orders, both gonochoristic and hermaphrodite species, simultaneous as well as sequential or consecutive, can be found. In sequential hermaphroditism (protandrous or protogynous), sex change in adult individuais invol

8. Expression Level of ABERRANT PANICLE ORGANIZATION1 Determines Rice Inflorescence Form through Control of Cell Proliferation in the Meristem1[W]
Two types of branches, rachis branches (i.e. nonfloral) and spikelets (i.e. floral), are produced during rice (Oryza sativa) inflorescence development. We previously reported that the ABERRANT PANICLE ORGANIZATION1 (APO1) gene, encoding an F-box-containing protein orthologous to Arabidopsis (Arabidopsis thaliana) UNUSUAL FLORAL ORGANS, suppresses precocious

9. AGAMOUS-LIKE 24, a dosage-dependent mediator of the flowering signals
The most dramatic phase change in plants is the transition from vegetative to reproductive growth. This flowering process is regulated by several interacting pathways that monitor both the developmental state of the plants and environmental cues such as light and temperature. The flowering-time genes FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF

10. Human centromere repositioning “in progress”
Centromere repositioning provides a potentially powerful evolutionary force for reproductive isolation and speciation, but the underlying mechanisms remain ill-defined. An attractive model is through the simultaneous inactivation of a normal centromere and the formation of a new centromere at a hitherto noncentromeric chromosomal location with minimal detrim
