Whether or not factors besides hyperphagia influence cellularity of adipose tissue in gold thioglucose (GTG)-treated mice was examined. The animals were treated with GTG (800 mg/kg body weight) or saline as control. Control and one of the GTG-treated groups were given a diet ad libitum and another of the GTG-treated groups was pair-fed to control. In GTG-treated group fed ad libitum, hyperphagi...
Complex chromosomal rearrangements (CCRs) are rare structural rearrangements involving three or more chromosomes. Balanced CCRs are often seen in phenotypically normal females who may later present with fertility problems. We report a 25-year old female with an adverse obstetric history and a de novo CCR involving chromosomes 7, 13 and 15 detected after GTG-banding. The de novo origin was confi...
A molecular cytogenetic study was performed on 48 infertile patients who were identified as carriers of balanced translocations (40 cases), inversions (6 cases) or insertions (2 cases) by means of banding cytogenetics. Cases with a Robertsonian translocation or pericentric inversion 2 or 9 were not included. In summary, 100 break-events occurred in these patients, and 90 different chromosomal r...
OBJECTIVE To describe the central nervous system (CNS) alterations present in a sample of oculo-auriculo-vertebral spectrum (OAVS) patients, trying to correlate them with other clinical features. METHOD Seventeen patients with diagnosis of OAVS were evaluated. All presented radiological evaluation of the CNS, normal GTG-Banding karyotype and clinical features involving at least two from the f...
Subtelomeric rearrangements are an important cause of both sporadic and familial idiopathic mental retardation (MR) and/or congenital malformation syndromes. We report on a cohort of 107 children with idiopathic MR and normal karyotype 450-550 band level by GTG banding screened for subtelomeric rearrangements by multiprobe fluorescence in situ hybridization (FISH). In these cases, five patients...
Populations of wild boar (Sus scrofa scrofa L.) of Central Europe frequently demonstrate polymorphism in chromosome number. This phenomenon is caused by chromosome rearrangements of the centric fusion type. The presence of Robertsonian translocations in the wild boar population may lead to one of three different karyotypes: 2n=36, 2n=37 and 2n=38. The aim of the study was to analyse the karyoty...
This communication presents the first case of complete trisomy 19q, prenatally detected by ultrasound investigation. Real-time high-resolution ultrasound examination was performed at 19 weeks of gestation. After termination of the pregnancy, autopsy investigation was done. GTG-banding, fluorescence in situ hybridization m-(FISH) analysis, and FISH analysis with a 19q subtelomeric specific probe...
Cytogenetic methods are widely used during diagnosis in many types of hematological malignancies. Classical methods like karyotyping using GTG banding technique and molecular methods like fluorescent in situ hybridization (FISH) are still gold standard in clinics all over the world. According to WHO 2008 classification the cytogenetic analysis is the basic diagnostic tool during the diagnosis o...
In this case report we present a child with an additional chromosome in the karyotype. The karyotypes of the boy and his parents were analyzed by use of a conventional banding technique (GTG) and fluorescence in situ hybridization (FISH). Probes painting whole chromosomes 12 and 18 were used in FISH. Cytogenetic examination of the parents revealed that his mother was carrying balanced reciproca...
Clyomys Thomas, 1916 is a semifossorial rodent genus of spiny rats represented by only one species, Clyomys laticeps, which inhabits the tropical savannas and grasslands of central Brazil and eastern Paraguay. Here we describe a new karyotype of Clyomys laticeps found in populations of Emas National Park, Goiás state, Brazil. The four analyzed specimens had a diploid number (2n) of 32 and a fun...
