1. Calpains of Leishmania braziliensis: genome analysis, differential expression, and functional analysis
BACKGROUND Calpains are proteins belonging to the multi-gene family of calcium-dependent cysteine peptidases that undergo tight on/off regulation, and uncontrolled proteolysis of calpains is associated with severe human pathologies. Calpain orthologues are expanded and diversified in the trypanosomatids genome. OBJECTIVES Here, we characterised calpains

2. Endophytic interaction of Bacillus sp. in micropropagated banana plantlets
Abstract: The banana tree is associated with different species of endophytic bacteria that can stimulate plant growth. However, further studies are needed to better understand the relationships between this group of bacteria and the host plant. The objective of this study was to investigate the localization of the EB-40 (Bacillus sp.) through anatomical and

3. Ultrastructure of phagocytes and oocysts of Nematopsis sp. (Apicomplexa, Porosporidae) infecting Crassostrea rhizophorae in Northeastern Brazil
Resumo Este trabalho descreve a morfologia ultraestrutural detalhada do fagócito encarcerando um oocisto de Nematopsis (Apicomplexa) encontrado em Crassostrea rhizophorae, na cidade de Maceió (AL), Brasil. Os hospedeiros muito infectados apresentavam valvas entreabertas com retração fraca e lenta dos músculos abdutores. Número variável de oócitos de

4. Floral resins of Philodendron adamantinum (Araceae): secretion, release and synchrony with pollinators
ABSTRACT Philodendron is the only genus of Araceae in which resin release occurs in the inflorescence. The resinous secretion adheres to the smooth body surface of the pollinating scarab beetles and allows attachment of pollen grains, making its transport possible. In order to understand the process of resin synthesis and release to the external environment,

5. Morphologic study of the effect of iron on pseudocyst formation in Trichomonas vaginalis and its interaction with human epithelial cells
BACKGROUND Trichomonas vaginalis is the aetiological agent of human trichomoniasis, which is one of the most prevalent sexually transmitted diseases in humans. Iron is an important element for the survival of this parasite and the colonisation of the host urogenital tract. OBJECTIVES In this study, we investigated the effects of iron on parasite prolifera

6. Beyond pollination: diversity of secretory structures during flower development in different legume lineages
ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions othe

7. Susceptibility of Phytomonas serpens to calpain inhibitors in vitro: interference on the proliferation, ultrastructure, cysteine peptidase expression and interaction with the invertebrate host
A pleiotropic response to the calpain inhibitor MDL28170 was detected in the tomato parasite Phytomonas serpens. Ultrastructural studies revealed that MDL28170 caused mitochondrial swelling, shortening of flagellum and disruption of trans Golgi network. This effect was correlated to the inhibition in processing of cruzipain-like molecules, which presented an

8. Bartonella henselae AS A PUTATIVE CAUSE OF CONGENITAL CHOLESTASIS
SUMMARY Severe anemia and cholestatic hepatitis are associated with bartonella infections. A putative vertical Bartonella henselae infection was defined on the basis of ultrastructural and molecular analyses in a three-year-old child with anemia, jaundice and hepatosplenomegaly since birth. Physicians should consider bartonellosis in patients with anemia and

9. EFEITO DA ASSOCIAÇÃO DO FATOR DE CRESCIMENTO E DIFERENCIAÇÃO 9 (GDF-9) E DO HORMÔNIO FOLÍCULO ESTIMULANTE (FSH) SOBRE O DESENVOLVIMENTO IN VITRO DE FOLÍCULOS PRÉ-ANTRAIS CAPRINOS EM CULTIVO IN SITU DE LONGA DURAÇÃO / EFFECT OF ASSOCIATION AND GROWTH FACTOR DIFFERENTIATION 9 (GDF-9) and hormone FOLLICLE STIMULATING (FSH) DEVELOPMENT OF IN VITRO PREANTRAL FOLLICLES GOATS IN FARMING IN SITU LONG
The aim of this study was to evaluate the effects of growth differentiation factor 9 (GDF-9) and follicle-stimulating hormone (FSH) on the in vitro survival, growth and steroidogenesis of caprine preantral follicles cultured for 16 days. Ovarian fragments were cultured in αMEM+ in the presence or absence of GDF-9 (200 ng/mL) and/or FSH (50 ng/mL) added

10. Terbinafine inhibits Cryptococcus neoformans growth and modulates fungal morphology
Cryptococcus neoformans is an encapsulated fungus that causes cryptococcosis. Central nervous system infection is the most common clinical presentation followed by pulmonary, skin and eye manifestations. Cryptococcosis is primarily treated with amphotericin B (AMB), fluconazole (FLC) and itraconazole (ITC). In the present work, we evaluated the in vitro effe

11. Investigação da microbiota endofítica onipresente em microplantas "axênicas / Investigation of ubiquitous endophytic microbiota in "axenic" microplants.
Tissue culture has been an important tool widely used for various purposes, among them the micropropagation has been highlighted due to the rapid production of healthy seedlings in a small space. Within this context, the term axenic plant has been distributed as an ideal to be achieved in this technique, which the search based on numerous methods that effect

12. Efeito da finasterida e da doxazosina sobre a próstata de rato : análise ultra-estrutural e da expressão dos colágenos tipo I e III e do TGF-b 1 / Finasteride and doxazosin effects on rat prostate : ultrastructural and type Iand type III and TGF-1 expression analyses
Finasteride and doxazosin are drugs used in the benign prostatic hyperplasia (BPH) treatment and, more recently, they re have been used in the prostate cancer (PCa) chemoprevention, mainly because their apoptotic effect in the prostatic epithelial cells. However, few attentions have been given to the effects of these drugs in the glandular stroma. Thus, the
