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...

Monoclonal and oligoclonal banding has been observed in electrophoretograms of serum, cerebrospinal fluid, and urinary protein from patients infected with the human immunodeficiency virus (HIV). This is the first report of kappa oligoclonal banding in the protein electrophoretograms for urine but not for serum of two patients with the acquired immune deficiency syndrome (AIDS). Both patients ha...

Wormlike micelles are an important class of surfactant micellar architectures that find use in applications ranging from consumer products to energy and nanomaterials. Many wormlike micellar systems exhibit a flow instability known as shear banding, characterized by an inhomogeneous flow field. Although many of the proposed mechanisms and theories for shear banding revolve around fluid microstr...

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...
