umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...

objectives the aim of this study was to evaluate the biological effects of opium on the number of peripheral blood cells and red blood cells (rbcs) indices in diabetic rats. materials and methods peripheral blood samples were collected from diabetic, opium-addicted, diabetic opium-addicted and normal male and female rats and hematological parameters were measured. results the mean number of whi...

abstract background phenyl ketonuria (pku) is a congenital metabolic disease. irreversible brain damage is the result of phenyl alanin accumulation, so its amount should be restricted in patients diet. in their diet, trace elements such as hem iron, folic acid, vitamin b12 and, etc are also limited, and could represent anemia. in this study, the frequency of anemia in pku patients in yazd was i...

A simple method for labeling human lymphocytes with Hg-197 is described. Lymphocytes were isolated from human blood and purified by the Ficoll-Hypaque method. Labeling was carried out by incubating viable cells suspended in saline with Hg-197 for different time intervals and at different temperatures. The labeling yield varied from 48% for 1 million cells to about 70% for 10 million cells after...

The patterns of cell proliferation and cell migration were studied in three patients with the Sezary syndrome using autoradiographic techniques. Cell labeling patterns following pulse labeling with tritiated thymidine in vivo indicated that Sezary cells proliferate actively in skin and in lymph nodes but that few if any Sezary cells proliferate in the peripheral blood. In two of the patients se...

In quantitative shotgun proteomic analyses by liquid chromatography and mass spectrometry, a rigid study design is necessary in order to obtain statistically relevant results. Hypothesis testing, sample size calculation and power estimation are fundamental concepts that require consideration upon designing an experiment. For this reason, the reproducibility and variability of the proteomic plat...

a graph of size n is said to be graceful when is possible toassign distinct integers from {0, 1, . . . , n} to its verticesand {|f(u)−f(v)| : uv ∈ e(g)} consists of n integers. inthis paper we present broader families of graceful graphs; these families are obtained via three different operations: the third power of a caterpillar, the symmetric product of g and k2 , and the disjoint :union: of g...

introduction: bombesin (bn), a 14-amino acid neuropeptide, shows high affinity for the human grp (gastrin releasing peptide) receptors, which are overexpressed by a variety of cancers, including prostate, breast, pancreas, gastrointestinal, and small cell lung cancer. aim was to prepare [6-hydrazinopyridine-3-carboxylic acid (hynic0), d-tyr6, d-trp8] - bn [6-14] nh2 that could be easily labeled...

Introduction Continuous artery-selective spin labeling (CASSL) [1] is one technique to image perfusion territories of cerebral arteries. To date, CASSL was only applied to major brain feeding arteries, but, recently, empirical findings have demonstrated that this method is even capable of selectively label the blood of individual branching intracranial arteries [2]. However, the exact behavior ...

This study reports the labeling of Gallium-Bleomycin (67Ga-BLM) complex as a radiopharmaceutical and optimization of its labeling conditions; pH, reaction time, temperature, concentration of bleomycin and its biodistribution in normal Bulb C mice. The biodistribution of the complex was compared with 67Ga-Cl3 in 11 selected organs including blood, liver, lung, spleen, muscle, skin, heart, kidney...
