BACKGROUND Vascular access is "the life line" for patients on chronic hemodialysis. The autogenous arteriovenous fistula provides the best access to the circulation because of low complication rate, long-term use, and lower cost, compared to arteriovenous graft and central venous catheter. The primary objective of this prospective study was to investigate the predictive value of vein diameter a...

Poly(vinylidene fluoride-trifluoethylene), P(VDF-TrFE), electrospun membranes were obtained from a mixture of dimethylformamide (DMF) and methylethylketone (MEK) solvents. The inclusion of MEK to the solvent system promotes a faster solvent evaporation allowing complete polymer crystallization during the jet travelling between the tip and the grounded collector. The main electrospinning process...

BACKGROUND AND OBJECTIVES Discrepancy between angiographic percent (%) diameter stenosis and fractional flow reserve (FFR) exists in non-left main bifurcation lesions. The aim of this study was to compare angiographic stenosis severity and FFR in jailed ostial left circumflex artery (LCX) lesions after left main (LM)-to-left anterior descending artery (LAD) crossover stenting. SUBJECTS AND ME...

Let (G) and min (G) be the largest and smallest eigenvalues of the adjacency matrix of a graph G. Our main results are: (i) If H is a proper subgraph of a connected graph G of order n and diameter D; then (G) (H) > 1 2D (G)n : (ii) If G is a connected nonbipartite graph of order n and diameter D, then (G) + min (G) > 2 2D (G)n : These bounds have the correct order of magnitude for large and D. ...

BACKGROUND Systemic lupus erythematosus (SLE) is an inflammatory, autoimmune, multiorgan disease often involving the central and peripheral nervous systems. OBJECTIVE To determine whether there is a selective small-diameter nerve fiber neuropathy in patients with SLE. DESIGN Cross-sectional study. SETTING Stavanger University Hospital, Stavanger, Norway. Patients Sixty patients with SLE, ...

Alpaca is the most important fibre producer of South American camelid species, and an important income for the Andean communities. Nowadays, the fibre diameter is considered the main selection criterion in alpaca populations all over the world. However, fibre diameter increases with the age of the animals, and it would be preferable to select those animals that maintain a thin fibre throughout ...

OBJECTIVE To determine the utility of the current diameter criterion of larger than 6 mm of the ABCDE acronym for the early diagnosis of cutaneous melanoma. DESIGN Cohort study. SETTING Dermatology hospital-based clinics and community practice offices. Patients A total of 1323 patients undergoing skin biopsies of 1657 pigmented lesions suggestive of melanoma. MAIN OUTCOME MEASURE The maxi...

two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. the minitubers were evaluated for several quality characters. the plant materials were from three cultivars, agria, marfona and savalan. the plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

Genotyping Mycobacterium tuberculosis in Lebanon on the national level may be beneficial for assessing patients and monitoring the therapeutic response to DOTS. This study aimed to characterize the spoligotypes of clinical isolates of M. tuberculosis patients collected between April 2004 and October 2005 from all Lebanese provinces. Isolates (n = 60) were cultured and identified by their bioche...
