ionospheric slab thickness is defined as the ratio of tec to maximum electron density of the f-region (nmf2), proportional to the square of the f2-layer critical frequency (fof2). it is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. it also reflects variation of the neutral temperature. therefore, ionos...
OBJECTIVE To evaluate the association between fraction of exhaled nitric oxide (FeNO) values and forced expiratory volume in the first second (FEV1) and the level of asthma control, as proposed by the Global Initiative for Asthma (GINA), in asthmatic children and adolescents attended at the National Institute of Women, Children and Adolescents Health Fernandes Figueira of Fundação Oswaldo Cruz ...
PURPOSE To investigate the protective effects of dexmedetomidine (Dex) against renal ischemia/reperfusion injury (IRI). METHODS Sprague-Dawley rats were randomly divided to sham group, IRI group and Dex group. The SD rats were subjected to 45 min of ischemia followed by eight weeks of reperfusion. Prior to ischemia, rats were either treated with Dex or not. Blood samples were collected for th...
Ischemia-reperfusion injury (IRI) due to hypotension is a common cause of human acute kidney injury (AKI). Hypoxia-inducible transcription factors (HIFs) orchestrate a protective response in renal endothelial and epithelial cells in AKI models. As human mucin 1 (MUC1) is induced by hypoxia and enhances HIF-1 activity in cultured epithelial cells, we asked whether mouse mucin 1 (Muc1) regulates ...
BACKGROUND Tissues fibrosis is caused by ischemia-reperfusion injury (IRI) and results in organ dysfunction. In this study, we aimed to investigate whether fibrosis occurs after uterine ischemia-reperfusion injury, and to investigate the effects of puerarin (Pur) on the fibrosis process in rats. MATERIAL AND METHODS Twenty-four female Wistar rats were randomly divided into three groups (8 in ea...
BACKGROUND Endothelial dysfunction contributes to ischemia-reperfusion injury (IRI) and is reduced by ischemic preconditioning (IPC). IPC may involve activation of ATP-sensitive potassium channels (K(ATP)). We determined whether modulation of K(ATP) channels occurs in endothelial IPC in humans. METHODS AND RESULTS IRI of the forearm was induced by inflating a blood pressure cuff to 200 mm Hg ...
BACKGROUND The effect of paricalcitol on renal ischemia-reperfusion injury (IRI) has not been investigated. We examined whether paricalcitol is effective in preventing inflammation in a mouse model of IRI, and evaluated the cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) pathways as a protective mechanism of paricalcitol. METHODS Paricalcitol (0.3 μg/kg) was administered to male C57BL/6 ...
The goal of this project is to attribute the authorship of excerpts from a set of New York Times articles to author Gina Kolata. The training data included labeled excerpts from New York Times as Gina Kolata vs other authors. We extracted and tried a multitude of features, setting the baseline as an SVM on 1000 most frequent words and then moving onto more complex features like Parts-of-Speech,...
BACKGROUND Irinotecan (IRI) is an integral part of colorectal cancer (CRC) therapy, but response rates are unsatisfactory and resistance mechanisms are still insufficiently understood. As fibroblast growth factor receptor 3 (FGFR3) mediates essential survival signals in CRC, it is a candidate gene for causing intrinsic resistance to IRI. METHODS We have used cell line models overexpressing FG...
Following a period of ischemia (local restriction of blood supply to a tissue), the restoration of blood supply to the affected area causes significant tissue damage. This is known as ischemia-reperfusion injury (IRI) and is a central pathological mechanism contributing to many common disease states. The medical complications caused by IRI in individuals with cerebrovascular or heart disease ar...
