The modalities to treat bleeding polyps include electrocautery snare polypectomy, adrenaline injection, clipping, argon plasma coagulation and surgery. We hereby describe an endoscopic banding ligation method for the management of bleeding gastric polyp in a patient receiving antiplatelet therapy. A 66-year-old man presented with a five month-history of intermittent tarry stool passage, nausea ...

OBJECTIVE To describe the chromosomal alterations in patients with mental retardation (MR) using G-banding karyotype analysis. METHOD A retrospective study of the results G-banding karyotype analysis of 369 patients investigated for MR was performed. Based on the structural rearrangements found, the authors searched all chromosomal regions related with breakpoints, and these were compared wit...

The engineering of new biomaterials requires an in-depth understanding of the structure and function of the native tissues. Optical coherence tomography (OCT) is a non-destructive technique that allows the visualization of the microstructure of biological tissues. The aim of this study was to determine if OCT could be used to identify geometric properties of tendons such as crimp pattern. Fresh...

BACKGROUND By application of a newly developed device for invasive pressure measurements, we have investigated band adjustments monitored by in vivo intraband pressures. With access to the port of the gastric banding device, pressures can be recorded inside the band system at rest and during bolus application with different adjustments of the band. METHODS 25 patients (mean age 38.7, mean BMI...

Introduction: Surgery for morbid obesity is constantly gaining popularity around the world, and laparoscopic adjustable gastric banding is among the most accepted standard procedures. Lately, growing evidence for long-term complications has been reported with this particular technique. While band erosion is described in 1% of patients, complete transmural migration is scarce but may lead to acu...

Routine cytogenetic analysis provides important information on diagnostic and prognostic relevance for hematological malignancies. However, it is often difficult to obtain good karyotypes, especially of cells from cases with acute lymphoblastic leukemia (ALL) because of poor morphology and spreading. Thus, detailed karyotyping can be hampered and even in case of a ‘normal karyotype’ according t...

The limiting factors in conventional cytogenetic analysis of cell culture, especially of solid tumors, include insufficient metaphases, overgrowth of abnormal mitotic cells by normal cells, and suboptimal quality of harvesting and banding. Despite the availability of numerous protocols to induce G-banding, as well as Q-, R-, and C-banding, occasions still arise in which the analysis is severely...

In situ hybridization of human chromosomes appears as one of the most attractive methods of gene mapping since it enables the locus being looked for to be directly visualized. This technique however includes a critical step which is the denaturation of chromosomal DNA by different procedures such as heat, alkali or acid treatment (1). These affect the chromosome structure and decrease the good ...

In spite of various cytogenetic works on suborder Heteroptera, the chromosome organization, function and its evolution in this group is far from being fully understood. Cytologically, the family Rhyparochromidae constitutes a heterogeneous group differing in chromosome numbers. This family possesses XY sex mechanism in the majority of the species with few exceptions. In the present work, multip...

Aortic banding in the rat has become a popular method to induce left ventricular (LV) hypertrophy and heart failure. However, because of often extensive intrathoracic adhesions and inflammatory cell infiltrates resulting from the traditional surgical approach, an uncomplicated second thoracic incision for genetic manipulation is impeded. In this study, we describe a novel surgical technique of ...
