Impact of A/H1N1 influenza in children at a Brazilian University Hospital

Braz. j. infect. dis; 22 (3), 2018
ABSTRACT Background A/H1N1 influenza is a viral disease that affects a significant part of the population mainly in winter, leading to increased number of medical consultations, hospitalizations and consequently care spending in emergency. Methods This is a case-series retrospective study, involving pa...

Impact of 1 25(OH) 2 D 3 on TG content in liver of rats with type 2 diabetes

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the effects of 1,25 dihydroxy vitamin D3 (1,25(OH)2D3) on the content of triglyceride (TG), as well as on the gene and protein expressions of adiponectin receptor 2 (AdipoR2), p38 mitogen-activated protein kinase (P38MAPK), and lipoprotein lipase (LPL) in the liver of rats...

Evaluating the use of fluorescence-based flow cytometry assay for dengue diagnosis using peripheral blood mononuclear cells

Abstract INTRODUCTION: Dengue virus (DENV) is the most important arthropod-borne viral disease worldwide with an estimated 50 million infections occurring each year. METHODS: In this study, we present a flow cytometry assay (FACS) for diagnosing DENV, and compare its results with those of the non-str...

Immunosuppressive mechanism of Hypoderma lineatum secreted serine esterase, a potential modulatory method used to inhibit transplant rejection

Background: Although immunosuppressive therapies have made organ transplantation a common medical procedure worldwide, chronic toxicity has a major issue for long-term treatment. One method to improve therapies and methods is the application of immunomodulatory agents from parasites such as Hypoderma lin...

Protective effects of Tribulus terrestris hydroalcoholic extract against cisplatin-induced germ cell apoptosis in male mice

Int. j. morphol; 36 (1), 2018
SUMMARY: Toxic effects of anti-cancer and other drugs on the normal tissues could be reduced by the herbal plants and their fractions. This study investigated the protective effect of Tribulus terrestris (TT) on Cisplatin- induced cytotoxicity germ cell apoptosis in male mice. In this experimental study,...

Vitiligo patients show significant up-regulation of aryl hydrocarbon receptor transcription factor

An. bras. dermatol; 93 (2), 2018
Abstract: IL-22 has been implicated in the pathogenesis of vitiligo. However, the role of aryl hydrocarbon receptor transcription factor that acts as a master regulator of IL-22-producing Th22 cells is not fully understood. The goal of this study was to investigate the expression pattern of aryl hydrocar...

Optimization of RT-PCR reactions in studies with genes of lignin biosynthetic route in Saccharum spontaneum

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Saccharum spontaneum has been used for the development of energy cane a crop aimed to be used for the production of second-generation ethanol, or lignocellulosic ethanol. Lignin is a main challenge in the conversion of cell wall sugars into ethanol. In our studies to isolate the genes the lignin...

Alternative splicing originates different domain structure organization of Lutzomyia longipalpis chitinases

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND The insect chitinase gene family is composed by more than 10 paralogs, which can codify proteins with different domain structures. In Lutzomyia longipalpis, the main vector of visceral leishmaniasis in Brazil, a chitinase cDNA from adult female insects was previously characterized. The predict...

Transmission of dengue virus from deceased donors to solid organ transplant recipients: case report and literature review

Braz. j. infect. dis; 22 (1), 2018
ABSTRACT Dengue fever is a vector-transmitted viral infection. Non-vectorial forms of transmission can occur through organ transplantation. We reviewed medical records of donors and recipients with suspected dengue in the first post-transplant week. We used serologic and molecular analysis to confirm the...

First evidence of Zika virus venereal transmission in Aedes aegypti mosquitoes

Mem. Inst. Oswaldo Cruz; 113 (1), 2018
BACKGROUND Aedes aegypti is considered the main Zika virus (ZIKV) vector, and is thought to be responsible for the 2015-2016 outbreak in Brazil. Zika positive Ae. aegypti males collected in the field suggest that vertical and/or venereal transmission of ZIKV may occur. OBJECTIVES In this study, we aime...
