BACKGROUND After Roux-en-Y gastric bypass (RYGB), a substantial number of patients do not achieve successful long-term weight loss. In cases of loss of restriction, the application of an adjustable gastric band ("salvage banding") over the gastric pouch, or gastrojejunostomy, could prevent weight regain or increase weight loss. The objective of this literature review is to provide an overview o...

BACKGROUND We have recently shown that angiotensin II-induced hypertrophy of cultured rat cardiomyocytes was partially blocked by an endothelin (ET) receptor antagonist (BQ123) selective for the ETA subtype, suggesting the possible involvement of endogenous ET-1 in the mechanism of cardiac hypertrophy in vitro. In the present study, we studied the in vivo blockade effects of BQ123 on cardiac hy...

Human metaphase chromosomes were photooxidized in the presence of methylene blue, a process that destroys guanine residues in DNA. Indirect immunofluorescence showed that such chromosomes reacted with a cytosine-specific antibody revealing a consistent fluorescent banding pattern by which each chromosome could be identified. The observed fluorescent patterns were the reverse of those produced i...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...

Shear-banding is commonly regarded as the "plasticity carrier" of metallic glasses (MGs), which usually causes severe strain localization and catastrophic failure if unhindered. However, through the use of the high-throughput dynamic nanoindentation technique, here we reveal that nano-scale shear-banding in different MGs evolves from a "distributed" fashion to a "localized" mode when the result...

Cytogenetic characterization of D. polymorpha was carried out using banding techniques such as C-banding, fluorochrome CMA3 and silver nitrate treatment. The diploid chromosome number of both investigated D. polymorpha forms (typical and albinotic) was the same 2n = 32 (NF = 56). The karyotype consisted of 5 pairs of metacentric, 7 pairs of submetacentric and four pairs of subtelo-acrocentric c...

Re Glossary Alkylating agent Alkylating agents involve reactions with guanine in DNA. These drugs add methyl or other alkyl groups onto molecules where they do not belong. This in turn inhibits their correct utilization by base-pairing and causes a miscoding of DNA. Aneuploidy The occurrence of one or more extra or missing chromosomes leading to an unbalanced chromosome complement, or any chrom...

BANDING of the pulmonary artery has been proposed as a therapeutic procedure for patients with a large left-to-right shunt and pulmonary artery hypertension not amenable to complete correction. It was theorized that by increasing the resistance to outflow from the right ventricle, and thus lowering the pulmonary artery pressure, the size of the left-to-right shunt would diminish, the high outpu...
