25. The potential inhibitory effect of cuminum cyminum, ziziphora clinopodioides and nigella sativa essential oils on the growth of Aspergillus fumigatus and Aspergillus flavus
The goals of this study were to evaluate the effectiveness of Cuminum cyminum, Ziziphora clinopodioides and Nigella sativa essential oils to inhibit the growth of Aspergillus fumigatus and A. flavus and to evoke ultrastructural changes. The fungi were cultured into RPMI 1640 media in the presence of oils at concentrations of 8, 6, 5, 4, 3, 2, 1.5, 1.25, 1, 0

26. Effect of Phytoaccumulation of Arsenic and Chromium on Structural and Ultrastructural Changes of Brake Fern (Pteris vittata)
Structural and ultrastructural changes caused by bioaccumulation of As and Cr in brake fern (Pteris vittata), a known arsenic hyperaccumulator, were investigated. Potted plants of brake fern were exposed to metal treatments of As and Cr for three weeks. Leaf, stem and root samples were collected periodically and fixed for LM (Light Microscopy), SEM (Scanning

27. Doença do armazenamento lisossomal causada pela ingestão espontânea de Sida carpinifolia em cervos Sambar (Cervus unicolor) cativos no Rio de Janeiro. / Lysosomal storage disease caused by spontaneous ingestion of Sida carpinifolia in captive-Sambar deer (Cervus unicolor) in Rio de Janeiro State, Brazil.
Cases of diseases induced by toxic plants in domestic herbivores are well reported throughout the world and have been studied also in Brazil. However, not much is known about the epidemiological and pathological aspectos of these conditions in free-living wildlife or bred in captivity. The risk for developing the toxicoses in captivity has been increasing, s

28. Alterações biológicas, bioquímicas e ultra-estruturais em Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) provocadas por extratos vegetais e compostos fenólicos / Changes biological, biochemical and ultrastructural in Spodoptera frugiperda (JE Smith, 1797) (Lepidoptera: Noctuidae) caused by plant extracts and phenolic compounds
The fall armyworm Spodoptera frugiperda is a polyphagous insect that causes damage in several crops, methods to control are often inefficient and this justifies the search for new forms of management. Thus, this study was to evaluate the effect of plant extracts and phenolic compounds on biological, biochemical and ultrastructural characteristics of S. frugi

29. Ação antibiótica de metabólito de Pseudomonas sp. no controle da Xanthomonas arboricola pv. pruni
Bacterial spot is caused by Xanthomonas arboricola pv. pruni (Xap), which is considered a major problem in peach orchards. Products based on copper and antibiotics are used to control and the biocontrol is a new alternative. The objective was evaluate the antibiotic activity of the metabolite produced by Pseudomonas sp. cultivated, for 15 days (28 °C, 100 r

30. Nanotechnology in ligature-induced periodontitis: protective effect of a doxycycline gel with nanoparticules
OBJECTIVES: The aim of this study was to test the efficacy of a locally applied 8.5% nanostructured doxycycline (DOX) gel in preventing alveolar bone loss in experimental periodontal disease (EPD) in rats by using the tapping mode atomic force microscopy (AFM). MATERIAL AND METHODS: EPD was induced in 24 Wistar rats. Animals were treated with the doxycycline

31. Análise da ultra-estrutura do tecido paratireóideo humano em solução para preservação de tecidos / Analysis of the ultrastructure of human parathyroid in solution for preservation of tissue
BACKGROUND: The cryopreservation of parathyroid tissue is employed in the surgical treatment of secondary hyperparathyroidism in patients with chronic kidney disease. During the period between surgical resection and cryopreservation of tissue, which requires a specialized laboratory, the tissue is stored in a cell culture solution, at 4 °C (solution for tra

32. Neurotoxic activity and ultrastructural changes in muscles caused by the brown widow spider Latrodectus geometricus venom
Brown widow spider (Latrodectus geometricus) venom (BrWSV) produces few local lesions and intense systemic reactions such as cramps, harsh muscle pains, nausea, vomiting and hypertension. Approximately 16 protein bands under reducing conditions and ~ 14 bands under non-reducing conditions on a 12.5% sodium dodecyl sulfate-polyacrylamide gel electrophoresis w

33. The immunomodulator glatiramer acetate influences spinal motoneuron plasticity during the course of multiple sclerosis in an animal model
The immunomodulador glatiramer acetate (GA) has been shown to significantly reduce the severity of symptoms during the course of multiple sclerosis and in its animal model - experimental autoimmune encephalomyelitis (EAE). Since GA may influence the response of non-neuronal cells in the spinal cord, it is possible that, to some extent, this drug affects the

34. Klebsiella pneumoniae: estudo molecular dos fatores de resistÃncia e caracterizaÃÃo ultra-estrutural da aÃÃo de antibiÃticos β-lactÃmicos
Klebsiella pneumoniae is an enterobacteria responsible for a high incidence of hospital infections usually caused by strains carrier of multidrug resistance and producer of broad spectrum -lactamase (ESBL). This study aimed to determine the genes involved in the formation of classical beta-lactamases and ESBLs in Recife-PE, Brazil, and investigate th

35. Morphological, biomechanical and biochemical analysis of tendon of obese Zucker (fa/fa) rats / Analise morfologica, biomecanica e bioquimica de tendão de ratos Zucker (fa/fa) obesos
Obesity is considered a worldwide epidemic, one of the biggest public health problems in many parts of the planet, which grows in alarming rates. In Brazil, the decline in rates of malnutrition has been accompanied by rising rates of overweight and obesity, which can be defined as the accumulation of abnormal or excessive fat which presents a risk to health.

36. Perfis das distroglicanas e morfo-fisiologia do lobo ventral da prostata de camundongos distroficos / Dystroglycans and laminin BETA 3 features on the prostate of mdx mice
The prostate is a fundamental accessory sex gland for the male reproductive process and the stroma-epithelium interaction has an important role in prostate structural maintenance and function. The basal membrane is an interaction link, offering mechanical and physiological support. Nowadays, different studies suggest that dystroglycan (DG), which is an adhes
