RESULTS
Due to partial diacetylene polymerization upon irradiation, two Raman peaks of C=C and C≡C stretching bands were observed around 1447 and 2060 cm(-1), respectively. The maximum intensities of the two peaks were obtained by positioning a focused laser spot on the surface of unlaminated film. For the dose range of 0-50 G...
CONCLUSIONS
The Raman intensity for C=C and C≡C peaks increases with an increase in the amount of diacetylene polymerization due to an increase in dose. This study shows the potential of Raman spectroscopy as an alternative for absolute dosimetry verifications with a high-spatial resolution of a few μm, but these findings need to ...
The aim of this study was to establish the method of isolating and culturing endothelial progenitor cells (EPCs) from human umbilical cord blood. Mononuclear cells (MNCs) from human umbilical cord blood were cultured by using culture system supplemented with endothelial cell-conditioned medium. The obtained two types o...
Bacterial cellulose acetate (BCA) at a low degree of substitution (DS) was prepared using acetic anhydride in the presence of N-methylimidazole (NMIM) as a catalyst. The acetylated reaction was studied in both solvent-free (heterogeneous) and N,N-dimethylacetamide/lithium chloride (DMAc/LiCl; homogeneous) systems, wher...
Bone mass in early adult life, or peak bone mass, is primarily under genetic control, although recent data suggest that alterations in nutrition and life style during growth may modify the genetic potential. Cross-sectional data indicated that upon completion of growth, there was a period of skeletal consolidation that...
The aim of this paper is to introduce a multilevel neighborhood
hypergraph partitioning for image segmentation. Our proposed
approach uses the image neighborhood hypergraph model introduced in
our last works and the algorithm of multilevel hypergraph
partitioning introduced by George Karypis. To evaluate the algorithm
performance, experiments were carried out on a group of gray scale
images. The results show that the proposed segmentation approach
find the region properly from images as compared to image
segmentation algorithm using normalized cut criteria.

In 1988, I retired from 30 years of teaching linguistics at UCLA, with a research specialty in the languages of Native North America and Mesoamerica. Since then, I've increasingly returned to an earlier interest in place name etymology, dating from my graduate student days at Berkeley. In 1993, I published a volume cal...

In recent years the National Physical Laboratory (NPL) has been developing a Kalman filter-based atomic clock ensemble algorithm. The algorithm is being used to form a composite time scale which will ultimately be employed to improve the stability of the UK's national time scale UTC(NPL) and its robustness to hardware ...

This paper presents a study where the potential of achieving autonomous net cleaning operations in commercial net pens is demonstrated through numerical simulations. Specifically, we investigated solutions for coping with the challenges that occur when obstacles appear in the path of an autonomous cleaning robot. Simul...
Plasma levels of thromboxane B2 (TXB2) and 6-keto PGF1 alpha in the blood samples taken at the coronary sinus and ascending aorta from twenty-one Japanese patients with variant angina and twenty with effort angina were measured by radioimmunoassay, the objective being to search for the contribution of prostanoids in co...
Paf-acether or platelet-activating factor (1-0-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is a phospholipid mediator of inflammation initially described as a potent platelet-aggregating compound. It is newly formed by a variety of cells including monocytes and is now recognized as a major mediator of cell-cell interac...
BACKGROUND & AIMS
Apart from its importance as an acid secretogogue, the role of histamine as a downstream target of gastrin has not been fully explored. Previous studies have shown that the combination of hypergastrinemia and Helicobacter infection resulted in accelerated gastric cancer in mice. We used this model to examine the role o...
METHODS
Male hypergastrinemic mice (INS-GAS mice) were infected with Helicobacter felis and given the CCK2/gastrin receptor antagonist YF476 and/or the histamine H2-receptor antagonist loxtidine for 3 or 6 months. In addition, mice were treated with omeprazole alone or in combination with either YF476 or loxtidine for 3 months...
RESULTS
Mice treated with YF476 or loxtidine alone showed partial suppression of both gastric acid secretion and progression to neoplasia. The combination of YF476 plus loxtidine treatment resulted in nearly complete inhibition of both parameters. YF476 and/or loxtidine treatment did not alter the overall level of H. felis col...
CONCLUSIONS
The combination of CCK2/gastrin- and histamine H2-receptor antagonists has synergistic inhibitory effects on development of gastric atrophy and cancer in H. felis/INS-GAS mice, while the proton pump inhibitor showed no such effects. These results support an important role for the gastrin-histamine axis in Helicobacter-...
Specific crystallographic planes of binary colloidal crystals consisting of silica nanoparticles are two-dimensionally replicated on the surface of gold nanoplates. The selectivity of the surface patterns is explained by the geometrical characteristics of the binary colloidal crystals as templates. The binary colloidal...
BACKGROUND
Acute pancreatitis is a common disease with wide clinical variation and its incidence is increasing. Acute pancreatitis may vary in severity, from mild self-limiting pancreatic inflammation to pancreatic necrosis with life-threatening sequelae. Severity of acute pancreatitis is linked to the presence of systemic organ ...
AIM AND OBJECTIVES
The present study was aimed to assess the clinical profile of acute pancreatitis and to assess the efficacy of various severity indices in predicting the outcome of patients.
METHODOLOGY
This was a prospective study done in Sri Ramachandra Medical College and Hospital from April 2012-September 2014. All patients with a diagnosis of acute pancreatitis were included in this study. Along with routine lab parameters, serum amylase, lipase, lipid profile, calcium, CRP, LDH, CT abdomen, CXR and 2D Echo was d...
RESULTS
A total of 110 patients were analysed. 50 patients required Intensive care, among them 9 patients (18%) died. 20 patients (18.2%) had MODS, 15 patients (13.6%) had pleural effusion, 9 patients (8.2%) had pseudocyst, 2 patients(1.8%) had hypotension, 2 patients(1.8%) had ARDS and 2 patients(1.8%) had DKA. In relation to...
CONCLUSION
Initial assessment of severity by CRP, LDH and lipase could be reliable indicators of outcome in acute pancreatitis.Salvation through Slavery: Chiricahua Apaches and Priests on the Spanish Colonial Frontier (review)

Picocyanobacteria (cells <2 µm) can be found either as single-cells (Pcy) or embedded in a mucilaginous sheath as microcolonies or colonies (CPcy). It has been demonstrated that phenotypic plasticity in picocyanobacteria (i.e. the capability of single-cells to aggregate into colonies) can be induced as a response to gr...

Very deep-submicron technologies pose new challenges to IC testing. In particular, crosstalk and transient faults are difficult to detect with traditional methods. Online testing techniques can detect these faults, however, and a new approach extends these techniques to include gross-delay faults. Moreover, this approa...
