Brote de síndrome pulmonar por hantavirus, Tucumán, Argentina
Outbreak of hantavirus pulmonary syndrome in Tucumán, Argentina

Medicina (B.Aires); 78 (3), 2018
Se describe un brote de síndrome pulmonar por hantavirus en el departamento de Burruyacú, provincia de Tucumán. La detección en 2016 de un caso de hantavirosis en una joven de 23 años -en ese momento considerado el primero ocurrido en dicha provincia- promovió un estudio epidemiológico exhaustivo,...

Performance of the IS6110-TaqMan® assay in the diagnosis of extrapulmonary tuberculosis from different biological samples

Abstract INTRODUCTION: This study evaluated the performance of the IS6110-TaqMan® assay in different types of biological samples and tissues for laboratory diagnosis of extrapulmonary tuberculosis. METHODS: 143 biological samples and tissues from patients with suspected extrapulmonary tuberculosis fro...

Genetic variants related to angiogenesis and apoptosis in patients with glioma

Arq. neuropsiquiatr; 76 (6), 2018
ABSTRACT Background Glioma, the most common primary malignant brain tumor in adults, is highly aggressive and associated with a poor prognosis. The objectives of this study were to evaluate the association of genetic polymorphisms related to angiogenesis and apoptosis with gliomas, as well as comorbidi...

A curcumin derivative J147 ameliorates diabetic peripheral neuropathy in streptozotocin (STZ)-induced DPN rat models through negative regulation AMPK on TRPA1

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the specific molecular mechanisms and effects of curcumin derivative J147 on diabetic peripheral neuropathy (DPN). Methods: We constructed streptozotocin (STZ)-induced DPN rat models to detected mechanical withdrawal threshold (MWT) in vivo using Von Frey filaments. I...

Interleukin-4 protects from chemotherapy-induced peripheral neuropathy in mice modal via the stimulation of IL-4/STAT6 signaling

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the possible role of IL-4 signaling pathway in vincristine-induced peripheral neuropathy. Methods: The mouse model of vincristine-induced peripheral neuropathy and interleukin (IL)-4 knockout mice were utilized to investigate the possible role of IL-4 signaling pathwa...

Efecto de la activación del receptor sensor de calcio sobre la expresión de genes lipogénicos en células HepG2

Introduction: The Calcium Sensing Receptor (CaSR) is expressed in human fat cells, and its stimulation may be associated with adipose tissue dysfunction. The multisystemic character of obesity and the search of deepening the scope of the activation of CaSR in this disorder allows us to study the response...

The protection effect and mechanism of hyperbaric oxygen therapy in rat brain with traumatic injury

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate the effect of hyperbaric oxygen therapy (HBOT) on traumatic brain injury (TBI) outcome. Methods: The modified Marmarou's weight drop device was used to generate non-lethal moderate TBI rat model, and further developed in vitro astrocytes culturing system. Then, we anal...

Cloning and heterologous expression of a hydrophobin gene Ltr. hyd from the tiger milk mushroom Lentinus tuber-regium in yeast-like cells of Tremella fuciformis

Background: Hydrophobins are small proteins secreted by filamentous fungi, which show a highly surface activity. Because of the signally self-assembling abilities and surface activities, hydrophobins were considered as candidates in many aspects, for example, stabilizing foams and emulsions in food produ...

Transcriptome profiling and digital gene expression analysis of genes associated with salinity resistance in peanut

Background: Soil salinity can significantly reduce crop production, but the molecular mechanism of salinity tolerance in peanut is poorly understood. A mutant (S1) with higher salinity resistance than its mutagenic parent HY22 (S3) was obtained. Transcriptome sequencing and digital gene expression (DGE) ...

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...
