Serum Ischemia-Modified Albumin in Preterm Babies with Respiratory Distress Syndrome

Infants with respiratory distress syndrome (RDS) may suffer from severe hypoxia, asphyxia. In this study, we aimed to evaluate serum ischemia-modified albumin (IMA) level as a diagnostic marker for hypoxia in preterm infants with RDS. Thirty-seven premature newborns with RDS were allocated as the study group and 42 healthy preterm neonates were selected as the control group. IMA was measured as absorbance unit (ABSU) in human serum with colorimetric assay method which is based on reduction in albumin cobalt binding. IMA levels were significantly higher in neonates with RDS as compared to the control group (P < 0.001). Cut-off value of IMA (ABSU) was 0.72, the sensitivity level was 91.9 %, the specificity was 78.6 %, positive predictive value was 79.1 % and negative predictive value was 91.7 % at RDS. Area under curve values was 0.93 (P < 0.001; 95 % CI, 0.88–0.98) in the receiver operating characteristic curve. We concluded that elevated blood IMA levels might be accepted as a useful marker for hypoxia in newborn with RDS.     

Effect of thiazide drug compound on the testicular protein and cholesterol contents of albino rat

In this study the effect of thiazide diuretic compound on the protein and cholesterol contents in the testes of albino rats as the experimental model. The drug thiazide was administered orally daily for 10,20 and 30 days at the dose of 100mg/kg body weight. Total protein decrease in the testes of rats were evidenced may be due to the side effects of thiazide drug compound which is linked with the hyponatremia and protein metabolism. An elevated level of cholesterol contents observed in thiazide treated rats also revealed that the side effect of drug compound thiazide and also may be due to the stimulation of catecholamine which is stimulated therefore, the biochemical estimation such as protein and cholesterol in the testes after the thiazide treatment determined the effectiveness of diuretic drug compound would provide clinical evidences of their side effects.     

Enacting silence: Residual categories as a challenge for ethics,information systems,and communication

Residual categories are those which cannot be formally represented within a given classification system. We examine the forms that residuality takes within our information systems today, and explore some silences which form around those inhabiting particular residual categories. We argue that there is significant ethical and political work to be done in exploring residuality.     

Sands modeling constrained by high-resolution seismic data

In the phase of field evaluation, the changing of interwell reservoir may be out of control if the geological model was built only on well data due to few existing wells. The uncertainty of the interwell reservoir interpolation based only on well data can be decreased by comprehensive utilization of geological, logging and seismic data, especially by using highly relative seismic properties from 3D seismic data adjusted by well point data to restrict interpolation of geological properties. A 3D-geological model which takes the sand body as the direct modeling object was built through stacking the structure, reservoir and water/oil/gas properties together in 3D space.

Free-Space Optical communication using visible light

INTRODUCTION A growing and seemingly insatiable bandwidth demand in the marketplace is bring Free-Space Op- tical (FSO) technology into the carrier space as a means of broadband access for closing the “last mile” connectivity gap throughout metropolitan networks. Terrestrial short-range FSO systems which are gen- erally point-to-point links between buildings on the campus or different buildings of a company can be used to setup wireless communication networks or to supplement radio a…     

整数规划中精确罚函数的一般形式

In this paper, the general exact penalty functions in integer programming were studied. The conditions which ensure the exact penalty property for the general penalty function with one penalty parameter were given and a general penalty function with two parameters was proposed.     

Silent or Stealth Retractions,the Dangerous Voices of the Unknown,Deleted Literature

Retractions serve as one perspective of the publishing process, and can offer vast insight into the problems associated with basic research, with the traditional publishing platform, or with policies. Some established retraction guidelines exist, such as those established by the Committee on Publication Ethics, or COPE. This essay provides a perspective of stealth or silent retractions within the broader concept of retractions, and within the framework of the COPE retraction guidelines. The issue of opaque retraction notices, especially in the case of COPE members, as well as the prominence of questionable retraction policies among select “predatory” open access publishers, is emphasized. Select clear examples are provided.
