in recent years stock exchange has become one of the most attractive and growing businesses in respect of investment and profitability. but applying a scientific approach in this field is really troublesome because of variety and complexity of decision making factors in the field. this paper tries to deliver a new solution for portfolio selection based on multi criteria decision making literatu...

Shine-Dalgarno (SD) sequence has been considered as one of the common features of 5' end untranslated region (5'UTR) of prokaryotic transcripts. However, more leaderless bacteria and archaea mRNAs are being increasingly reported in recent years. To understand the distribution of SD-led genes and non-SD-led genes, we have analyzed 162 completed prokaryotic genomes leading to various new conclusi...

Background Stent underexpansion is a major risk factor for in-stent restenosis and acute in-stent thrombosis1Intravascular ultrasound (IVUS) is one of the standards for detection of stent underexpansion (de Feyter et al. 1999; Mintz et al., 2001). StentBoost (SB) enhancement allows an improved angiographic visualization of the stent (Koolen et al., 2005). Aim of work Comparison of stent expan...

structural codes vis-a-vis structural counts, like polynomials of a molecular graph, areimportant in computing graph-theoretical descriptors which are commonly known astopological indices. these indices are most important for characterizing carbon nanotubes(cnts). in this paper we have computed sadhana index (sd) for phenylenes and theirhexagonal squeezes using structural codes (counts). sadhan...

PURPOSE The purpose of this study was to establish a normal reference database for fixation stability measured with the bivariate contour ellipse area (BCEA) in the Macular Integrity Assessment (MAIA) microperimeter. METHODS Subjects were 358 healthy volunteers who had the MAIA examination. Fixation stability was assessed using two BCEA fixation indices (63% and 95% proportional values) and t...

The assessment of the body fluid status is one the most challenging tasks in clinical practice. Although there are many methods to assess the body fluid status of patients, none of them is fully satisfactory in contemporary medical sciences. In the article below, we compare the results of measurements performed by experienced and inexperienced examiners based on the inferior vena cava/aorta dia...

UC (ulcerative colitis) patients have an increased risk of developing colorectal cancer compared with the normal population. The cause underlying this higher risk is not fully defined but includes nutritional and environmental factors concomitant with genetic alterations. We aimed to evaluate genetic stability in the colonic tissue of UC patients in clinical remission compared with the healthy ...

PURPOSE Although rectal cancer is a very common malignancy and has an improved cure rate in response to oncological treatment, research on rectal-cancer survivors' sexual function remains limited. Sexual dysfunction (SD) after rectal cancer treatment was measured, and possible predisposing factors that may have an impact on the development of this disorder were identified. METHODS Patients un...
