Bleeding from oesophageal varices is the commonest cause of significant upper gastrointestinal bleeding in Sri Lanka. Endoscopic band ligation is an effective method in the management of varices. But the cost of banding equipment is high, unaffordable for a majority of our patients. We have devised a cheap method to carry out banding of varices. Banding of varices using this technique was carri...

Similarities and differences become evident from comparisons of centromeric and non-centromeric banding patterns in plant and animal chromosomes. Similar to C and G-banding in animals (at least most of the reptiles, birds and mammals), centromeric and nucleolus-organizing region bands as well as interstitially and/or terminally located non-centromeric bands may occur in plants, depending on the...

Identification of individual chromosomes by banding patterns is an essential step for physical genetic mapping of fish and other species where chromosomes are numerous and similar in size. Many techniques, such as Giemsa banding, reverse banding and restriction enzyme banding can generate well-defined patterns on mammalian chromosomes. However, these linear banding techniques are not useful wit...

This paper proposes a multitoning method based on threshold modulation using a Modified Jointly Blue Noise Mask (MJBNM) to reduce banding artifacts. Since banding artifacts appear as uniform dot distributions around the intermediate output levels, such halftone patterns result in discontinuity and a visually unpleasing output in smooth transition regions. Therefore, to reduce these banding arti...

Denoting the ordered parental genotypes at a marker as AB and CD, the F1 progeny have genotypes either AC, AD, BC or BD. However, precise genotypes for the genetic markers were not observed; rather, each marker exhibited two, three or four distinct banding patterns across the set of progeny. The connection between banding patterns and the underlying genotypes was inferred as part of the process...

Shear banding is a flow-induced phenomenon observed in a wide variety of materials, including highly entangled polymers, self-assembled surfactants, colloidal suspensions, and pastes. Its rheological and macroscopic signatures have been well-studied for over a decade, yet surprisingly little is known about the underlying microstructural mechanism(s) that give rise to shear banding in soft matte...

of evidence • Patients undergoing various bariatric surgical procedures lost an average of 61.2% of their excess weight (varying from 47.5% for gastric banding to 70.1% for biliopancreatic diversion or duodenal switch procedures) • Perioperative mortality was relatively low (varying from 0.1% for banding, 0.5% for bypass, to 1.1% for biliopancreatic diversion or duodenal switch) • Most patients...

The cytological features including chromosome number, karyotypic characteristics, C-banding and silver NOR-banding were investigated in a local cultivar of Allium sativum L., from Turkey. Actual lengths, relative lengths, L/S arm ratios of mitotic chromosomes were calculated from best six metaphase plates. Only Chromosome 5 was submedian, all the others were median. C-banding was observed on 4 ...

The karyotype of the domestic goose A. cygnoides was characterised on the basis of R and C bands. Chromosomal preparations obtained from an in vitro culture of blood lymphocytes were stained by means of the RBG and CBG banding techniques. The first nine pairs of chromosomes were analysed by the R banding technique, while fourteen pairs of chromosomes were analysed by the C banding technique. Th...
