Research ArticleOpen accessIn the author namesInfluence of a Low-Level Semiconductor Gallium Arsenate Laser in Experimental Envenomation Induced by Bothrops atrox Snake VenomElziliam Aranha De Sousa, José Adolfo Homobono Machado Bittencourt, Nayana Keyla Seabra De Oliveira et al.Bothrops atrox is responsible for the majority of snakebite accidents in Brazilian Amazon and its venom can cause prominent local tissue damage. Experimental groups consisted of five male mice, each administered either B. atrox Venom (VB), B. atrox Venom + Antivenom (VAV), B. atrox Venom + Laser (VL), B. atrox Venom + Antivenom + Laser (VAVL), or Sterile Saline Solution … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 4 · 29 Dec 2012 · 7,501 accessesView PDFCite
Research ArticleOpen accessIn the author namesPhoretic Association and Facultative Parasitoidism Between Megaselia scalaris and Blowflies, Under Natural ConditionsJose Antonio Batista-Da-SilvaProblem statement: This is the first time that a phoretic association and facultative parasitoidism between Megaselia scalaris and blowflies (Diptera: Calliphoridae) has been reported under natural conditions. Approach: All fly specimens were collected in the mangrove swamp in Itaborai, RJ, Brazil. Results: A total of 291 flies were collected belonging to four (04) species of the family Calliphoridae: Chrysomya megacephala … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 28 Apr 2012 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the author namesProgressive Resistance Training on Elderly HIV+ Patients: Does it Work?Paula Maria Loiola De Souza, Wilson Jacob Filho, José Maria Santarém et al.Elderly people present significant alterations on body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation by increasing aging effects on body composition and muscle strength. Resistance exercises are prescribed by major health organizations for improving fitness and promoting a shift towards a healthier and more independent aging. In addition, recovering strength and … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the author namesUltrastructural Evidences of Hepatitis B Infection in Human Liver Biopsies Disclose Complex Assembly and Morphogenesis Pathways for Hepatitis B VirusViviana Falcon, Ivon Menéndez, Nelson Acosta-Rivero et al.Despite of recent advances on acknowledge of hepatitis B virus (HBV) structure and biology, little is known about the morphogenesis and release of virions. In this study, the ultrastructural analysis of HBV components in liver biopsies from chronically HBV-infected patients disclosed complex assembly and morphogenesis pathways for HBV. HBV core (HBcAg) and surface (HBsAg) antigens were specifically identified in all … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvidences of Hepatitis C Virus Replication in Hepatocytes and Peripheral Blood Monocuclear Cells from Patients Negative for Viral RNA in SerumViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.In this study, we examined the expression of hepatitis C virus (HCV) components in hepatocytes and peripheral blood mononuclear cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA. The samples obtained from 25 randomly selected patients (13 of 25 patients showed no histological evidences of chronic hepatitis and had normal serum ALAT and GGTP levels) were … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,173 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,909 accessesView PDFCite
