Complete esophageal obstruction is a rare complication of endoscopic variceal banding, with only 6 cases in the English literature since the introduction of endoscopic variceal banding in 1986. We report a case of complete esophageal obstruction following esophageal banding due to entrapment of part of a sliding hiatal hernia. To our knowledge, our case is one of few with esophageal obstruction...

Metallic glasses due to their unique combination of physical and chemical properties have a great potential in various applications: materials for construction, medical, MEMs devices and so on. The deformation mechanism in metallic glasses is very much different from that in conventional crystalline materials and not yet fully understood. Here we are trying to find out what drives shear deforma...

The revision of main and alternative banding sequences in chromosome I (AB) have been made for all 14 species of the Chironomus plumosus (Linnaeus, 1758) group. New version of mapping had been suggested for 14 out of 22 banding sequences of arm A. Mapping of 18 banding sequences in arm B have been made for the first time according to Maximova-Shobanov system. Phylogenetic relationships of the b...

The fourth case of spontaneous closure of a ventricular septal defect in a patient having prior pulmonary artery banding is reported. Statistics to date indicate that yenfricular septal defects in patients who require banding may close with lesser frequency than those for which banding is not required. The apparent lower incidence of spontaneous closure of these defects should not Influence the...

Bulk metallic glasses (BMG’s) have long been materials of interest due to their high strength, high elastic limit, wear and corrosion resistance, and ease of thermoforming above the glass transition temperature [1]. The primary technical challenge of implementing BMG’s in engineering applications is their tendency to fail catastrophically via highly localized shear banding events. Though the el...

The main purpose of this work is to reveal the effects carboxyl-terminated butadiene–acrylonitrile (CTBN) rubber particles on fracture and tensile behavior anhydride-and amine-cured epoxy/CTBN blends. In study, 1 wt.%, 3 5 7 10 wt.% 15 CTBN were added two different epoxy-hardener systems. CTBN/epoxy blends prepared by ultrasonic mixing device curing processes determined DSC analysis. As fractio...

The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two ...

The control banding method, or "control banding", is a simplified risk assessment system for chemical handling tasks. This system is supposed to provide assessment results of reasonable quality without expert involvement. The objective of this study was to evaluate the appropriateness of control banding judgment on the basis of workplace safety. A common approach for assessing workplace risk, w...

BACKGROUND Esophageal variceal banding may be less likely to cause bacteremia than sclerotherapy. The existing data about the frequency of bacteremia after esophageal variceal banding are conflicting, and few studies include both banding and sclerotherapy. AIMS We conducted a prospective randomized controlled trial to compare the frequency of bacteremia after esophageal variceal banding and s...
