The NADPH:O2 oxidoreductase catalyzing the respiratory burst in activated phagocytes from healthy individuals is not operative in phagocytes from patients with chronic granulomatous disease (CGD). In a microscopic slide test using the dye nitroblue tetrazolium (NBT), carriers of X-linked CGD can be recognized by a mosaic pattern of NBT-positive and NBT-negative cells, governed by the expression...

OBJECTIVE To assess the neutrophil function in thalassemia major (TM) patients and compare it with the control group, and to recognize its relevant factors. METHODS This was a retrospective cohort study, which was carried out from October 2007 to February 2008 in the Thalassemia Research Center in Boo Ali Sina Hospital in Sari, Mazandaran, north of Iran. The study population consisted of TM p...

The determination of gene expression patterns in three dimensions with cellular resolution is an important goal in developmental biology. However the most sensitive, efficient, and widely used staining technique for whole-mount in situ hybridization (WMISH), nitroblue tetrazolium (NBT)/5-bromo-4-chloro-3-indolyl phosphate (BCIP) precipitation by alkaline phosphatase, could not yet be combined w...

This paper presents VEC-NBT, a variation on the unsupervised graph clustering technique VEC, which improves upon the performance of the original algorithm significantly for sparse graphs. VEC employs a novel application of the state-ofthe-art word2vec model to embed a graph in Euclidean space via random walks on the nodes of the graph. In VEC-NBT, we modify the original algorithm to use a non-b...

A long-term bone marrow culture system has been derived for maintenance and proliferation of human hemopoietic stem cells and granulocytes in vitro for up to 20 wk. The granulocytes generated in these cultures at 8 wk were comparable to fresh human peripheral blood granulocytes in physiologic properties, including phagocytosis, degranulation, respiratory burst, and bacterial killing: individual...

Tempol catalyzes the formation of H(2)O(2) from superoxide and relaxes blood vessels. We tested the hypothesis that the generation of H(2)O(2) by tempol in vascular smooth muscle cells during oxidative stress contributes to the vasorelaxation. Tempol and nitroblue tetrazolium (NBT) both metabolize superoxide in vascular smooth muscle cells, but only tempol generates H(2)O(2). Rat pressurized me...

The main aim of this study was to compare selected nonspecific immunity parameters in 14 allergic and 12 healthy horses. Each animal was assessed according to the following parameters: in vitro functional capacity of phagocytic cells using the nitro blue tetrazolium chloride reduction test, both spontaneous (NBT) and zymozan stimulated (NBTs), and ingestion capacity of phagocytic cells using a ...

Genetic parameters of litter traits and their relationships with farrowing kinetics traits were estimated in a Large White population to examine the impact of selection for litter size on perinatal mortality and one of its main determinants, farrowing kinetics. Data were collected on 2,947 farrowings from 1,267 sows between 1996 and 2004. Litter traits included the number born in total (NBT), n...

PURPOSE The aim of this study was to retrospectively observe and analyze the long-term treatment outcomes of 191 elderly patients with esophageal squamous cell cancer (ESCC) who were treated with californium-252 (252Cf) neutron brachytherapy (NBT) in combination with external beam radiotherapy (EBRT). MATERIAL AND METHODS From January 2002 to November 2012, 191 patients with ESCC underwent NB...
