OBJECTIVE To report an original method of ossicular reconstruction with intact stapes and absent malleus. Ossiculoplasty is performed with a total ossicular replacement prosthesis positioned from the stapes footplate to the under-surface of the tympanic membrane, using a Silastic banding technique to stabilize the prosthesis. STUDY DESIGN A prospective study of ossicular reconstruction using ...

Multicolor spectral karyotyping (SKY) was performed on bone marrow samples from 50 patients with multiple myeloma (MM) in anticipation of discovering new previously unidentified translocations. All samples showed complex karyotypes with chromosome aberrations which, in most cases, were not fully characterized by G-banding. Patients of special interest were those who showed add(14)(q32), add(8)(...

Between October 1972 and April 1977 15 patients underwent definitive repair of a ventricular septal defect (VSD) and reconstruction of the pulmonary artery at the banding site. This report presents pre- and post-operative haemodynamic data in 12 patients, seven to 22 years after banding (mean 13.4). Banding of the pulmonary artery was performed before the age of 6 months (mean 4). The indicatio...

The aim of this work is to characterize Nephilengys cruentata in relation to the diploid number, chromosome morphology, type of sex determination chromosome system, chromosomes bearing the Nucleolar Organizer Regions (NORs), C-banding pattern, and AT or GC repetitive sequences. The chromosome preparations were submitted to standard staining (Giemsa), NOR silver impregnation, C-banding technique...

Head and neck carcinomas represent the sixth most frequent type of cancer in the world, and 90% are derived from squamous cells (HNSCC). In this study of 15 HNSCC cases, extensive aneuploidy was detected by G banding in most tumors. The most frequently observed numerical changes involved gain of a chromosome 22, and loss of chromosomes Y, 10, 17, and 19. The most frequent structural alteration ...

background pulmonary artery banding (pab) is a technique of palliative surgical therapy used by congenital heart surgeons as a staged approach to operative correction of congenital heart defects. materials and methods we report 5- year experiences from january 2011 to january 2016 of imam reza hospital center (a tertiary referral hospital in mashhad city, north east of iran) that consist of 50 ...

BACKGROUND AND OBJECTIVE Cross-species color banding (RxFISH) is a new FISH technology based on the use of differentially labeled gibbon chromosome probes to obtain a specific color banding pattern for each human chromosome. The aim of the study was to test the RxFISH technique for better characterization of complex karyotypes in patients with T-prolymphocytic leukemia (T-PLL). DESIGN AND MET...

INTRODUCTION Pulmonary artery (PA) banding is a procedure associated with high morbidity and mortality rates. It however can effectively palliate several forms of congenital heart lesions with increased pulmonary flow. Occasionally, to obtain an optimal degree of banding following operation, readjustment of the band is inevitable. We describe the technique of adjustable PA banding to prevent th...

autism is a complex neuropsychiatric disorder that manifests in early childhood. although the etiology is unknown yet but, new hypothesis focused on identifying the key genes related to autism may elucidate its etiology. the main objective of the present study was to verify the value of karyotyping in autistic children and identifying association between chromosome abnormalities and autism.we e...

Growth hormone (GH) is the most important hormone that controls somatic cell growth and syntheses of protein, fat, and carbohydrates. This study was conducted to identify gene polymorphism of GH-1 using PCR -single strand conformation polymorphism (SSCP) technique and its association with growth traits including condition factor (CF), body weight (BW) and total length (TL) in common carp (Cypr...
