Individuals of the same species may present different reproductive tactics depending on the environment in which they develop and mature. The present study aimed to define the gonadal development phases of males and females of Astyanax rivularis and to carry out a comparative analysis of the reproductive development of specimens captured in two isolated environments of the São Francisco River basin in Serra da Canastra, Brazil (Point 1: low vegetation and river showing calm and crystalline waters with small well formations; Point 2: current waters, and well-established areas of arboreal vegetation). Thus, the gonads of A. rivularis specimens were collected, fixed and processed with techniques for light microscopy. Five maturation phases of the females' reproductive cycle were established: immature, developing, spawning capable, regressing and regenerating. Three maturation phases of the males' reproductive cycle were observed: spawning capable, regressing, and regenerating. There are differences in the phases of gonadal development of A. rivularis between the two sampling points so that, possibly, animals upstream of the waterfall demonstrate a delay in the reproductive cycle in relation to animals downstream. 相似文献

Paracoccidioidomycosis is a common deep fungus infection in South America, particularly in Brazil. It is acquired through inhalation and primary involvement of lungs. Subsequently, dissemination may occur and oral mucosa is frequently affected and actually, in most of the cases the diagnosis is established because of the oral lesions. Thus, the role of the dentist is fundamental to correct diagnosis. However, the involvement of intestine is rarely reported. The current case describes a 36-year-old man who presented abdominal pain and intestinal constipation, being suspected and then confirmed as paracoccidioidomycosis after already be diagnosed with this disease by a dentist through oral manifestations. 相似文献

We report the genome sequence of a healthcare-associated MRSA type ST239 clone isolated from a patient with septicemia in Malaysia. This clone typifies the characteristics of ST239 lineage, including resistance to multiple antibiotics and antiseptics. 相似文献

Summary The differences between Anisopodus White, 1853 and Hyperplatys Haldeman, 1847 are discussed and the gender of the latter is corrected. Notes on Hyperplatys pusillus (Bates, 1863) are provided. Hyperplatys nigrisparsus is considered a new rank for H. pusillus nigrisparsus (Bates, 1885). This species is newly recorded from Brazil (Amazonas). Alcidion laetulum Bates, 1880 (currently Nealcidion laetulum), Alcidion costatum Monné & Martins, 1976 (currently Nealcidion costatum), and Nealcidion murinum Monné, 1998, are synonymized with Alcidion bispinum Bates, 1863 (currently Nealcidion bispinum). Anisopodus melzeri Gilmour, 1965 is transferred to Hyperplatys with a new record from the Brazilian state of Mato Grosso do Sul. Notes on a second specimen of Confluentia colombiana (Gilmour, 1950) are provided. Three new species are described from Ecuador: Nealcidion kayi n. sp. (Acanthocinini), Hyperplatys pichinchensis n. sp. (Acanthocinini) and Confluentia quijos n. sp. (Colobotheini). 相似文献

Radiotherapy is being performed in many situations as a curative approach for head and neck cancer instead of surgery due to the current novel coronavirus disease (COVID-19) pandemic. A recent publication reported that even hypofractionation was being conducted in order to reduce the daily exposure of both patients and the medical staff involved in cancer therapies. As a result, dental teams may be requested more frequently than usual to fabricate intraoral stents (IOS). Given that IOS may be a potential source of COVID-19 contagion, the main purpose of the present correspondence is to offer a guide on how health professionals may be safely presented in the room, on the management of the IOS and also how to sanitize the stents. 相似文献
