this paper reports results of a study regarding the activities of nano structure mn/γ-al2o3 and γ-al2o3 catalysts for oxidation of 2-propanol (as a model of volatile organic compound). nanostructure of catalysts was revealed using xrd, sem and tem techniques. catalytic studies were carried out in u-shaped packed bed reactor under atmospheric pressure and at the reaction temperature of 150- 500°...

PURPOSE This study was conducted to evaluate and demonstrate the efficacy of low prime volume completely closed cardiopulmonary bypass (LPVP) in arrested coronary artery bypass grafting (CABG). We improved the percutaneous cardiopulmonary support (PCPS) circuit to reduce the deleterious effects of cardiopulmonary bypass (CPB). METHODS Between April 1999 and May 2003, among 228 isolated CABG p...

an experiment was conducted on eight weak and anaemic goats revealed pale conjunctivae, increased heart rate, rough hair coat, dullness and depression. the haematology showed significantly decreased haemoglobin (7.37±0.16 g %), packed cell volume (pcv)(23.37±0.56%),total erythrocyte count (tec)(8.12±0.18 million/cumm), mean corpuscular haemoglobin (mch) (9.10±0.30 pg) and mean corpuscular volum...

three differentes continous cell lines (am 57. hela • vero) and primary cell culture of human embryo kidney are compared with regard to their .susceptibility for isolation of mumps v i r u s from saliva and cerebrospinal fluid. for this purfose the vero cell line appeared to be more suitable among the studied cell systems regarding the following reasons: it allows the highest pourcentage of mum...

OBJECTIVE To review the literature on the limitations and consequences of packed red blood cell transfusions, with particular attention to critically ill patients. METHODS The PubMed database of the National Library of Medicine was searched to find published articles on the indications, clinical utility, limitations, and consequences of red blood cell transfusion, especially in critically ill...

BACKGROUND Since the first facial allograft transplantation was reported in France in 2005, 18 cases have been performed in 4 countries and the rate is increasing. METHODS We have devised a survey to assess anesthesia-related management and rationale of facial allograft transplantation. It was sent to the lead anesthesiologists of the first 14 face transplants performed worldwide. RESULTS R...

A well crystallized sample of U 2A13C4 was obtained by melting the elemental components in a carbon crucible in a high frequency furnace. The crystal structure of this compound was determined from single-crystal diffractometer data of a twinned crystal: P 63mc, a = 342.2(1) pm. c 2323.0(3) pm. Z 2 , R 0.030 for 537 structure factors and 18 variable parameters. The structure can also be describe...

The tumour cell lines U937A and L929 form large, loosely packed colonies in vitro and can be killed by the cytokine tumour necrosis factor (TNF).

Objectives. Anemia is a major public health problem throughout the world which assumes prominence in pregnant mothers. Patients with severe anemia continue to present themselves at term or in labor. This study was conducted to compare the improvements in hematological parameters of patients receiving partial exchange blood transfusion and transfusion of packed cells without exchange. Methods. O...

The mechanisms that order cellular packing geometry are critical for the functioning of many tissues, but they are poorly understood. Here, we investigate this problem in the developing wing of Drosophila. The surface of the wing is decorated by hexagonally packed hairs that are uniformly oriented by the planar cell polarity pathway. They are constructed by a hexagonal array of wing epithelial ...
