1. Pseudocyphellae ontogeny and thallus anatomy in species of Punctelia Krog (Parmeliaceae, lichenized Ascomycota)
ABSTRACT The genus Punctelia has been traditionally characterized by the type and distribution of pseudocyphellae, medullary chemical substances and the shape of conidia, whereas its species have been distinguished using mainly the shape, location, abundance and size of pseudocyphellae. Given that Punctelia is not monophyletic, additional studies are needed

2. Total earlobe reconstruction with a superiorly based preauricular flap
Abstract: An 86-year-old woman was referred for treatment of a lentigo maligna melanoma on the left earlobe, confirmed by cutaneous biopsy. The resulting surgical defect involved the earlobe's full thickness. The authors outline a simple method for reconstructing the entire lobe in one stage, without grafts, whilst offering a pleasant appearance. Earlobe def

3. Membranous lipodystrophy: case report and review of the literature
AbstractMembranous lipodystrophy is a distinct type of membranocystic fat necrosis. It is associated with many local and systemic diseases, including vascular disorders. The histopathological changes which characterize this phenomenon are variably sized cysts in the fat lobules of the subcutaneous tissue, which are surrounded by eosinophilic membranes projec

4. Effect of scanner acoustic background noise on strict resting-state fMRI
Functional MRI (fMRI) resting-state experiments are aimed at identifying brain networks that support basal brain function. Although most investigators consider a ‘resting-state’ fMRI experiment with no specific external stimulation, subjects are unavoidably under heavy acoustic noise produced by the equipment. In the present study, we evaluated the influ

5. Regulatory role of semaforin-3A in the development of human T cells: inibitory effect on the migration of thymocytes mediated by the CXCL12. / Papel regulatório da semaforina-3A no desenvolvimento de células T humanas: efeito inibitório sobre a migração de timócitos mediada pela CXCL 12.
The thymus is the primary lymphoid organ, responsible for normal T cell development in vertebrates. This is a highly complex process that includes cell proliferation, death, migration as well as T cell receptor gene rearrangements. It takes place within the thymic lobules and depends on several types of interactions between developing thymocytes and the thym

6. Histology of the liver of Oligosarcus jenynsii (Ostariophysi, Characidae) from Los Padres Lake, Argentina
The liver is an organ notable for its sensitivity to a great variety of environmental factors. It is composed of a parenchyma divided into irregular lobules by the exocrine pancreas or hepatopancreas; the pancreatic cells are arranged around a branch of the portal vein. The hepatocytes are radially arranged in cords around a central sinusoid. The liver histo

7. Descrição da arquitetura foliar e análise morfométrica das folhas de Spathicarpa Hook (Araceae)
The study of leaf morphology has always played a significant role in plant taxonomy, especially in the identification of taxa which are defined by reproductive characteristics such as genus Spathicarpa Hook. (Araceae). The present study has as its objective: to describe leaf architechture patterns and to characterize by morphometric methods the leaves of Spa

8. 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

9. Anatomical study of the cerebellum of the Cebus apella monkey / Estudo anatômico do cerebelo do macaco Cebus apella
The gender Cebus, represented by four species and several subspecies, its found geographically distributed since Central America up to the south of South America however, its anatomy is still little well-known. Its from easy adaptation and can survive in small forests and restingas, but the continuous destruction of its habitat has been threatening, in a pro

10. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

11. Effect of hyperbaric oxygenation on the regeneration of the liver after partial hepatectomy in rats
The aim of the present study was to assess the influence of hyperbaric oxygenation (HBO) on rat liver regeneration before and after partial hepatectomy. Rats were sacrificed 54 h after 15% hepatectomy, liver and body weights were measured, and serum alanine transaminase (ALT) and aspartate transaminase (AST) activity and albumin levels were determined. The l

12. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal
