In a departure from traditional gene-centric thinking with regard to cytogenetics and cytogenomics, the recently introduced genome theory calls upon a re-focusing of our attention on karyotype analyses of disease conditions. Karyotype heterogeneity has been demonstrated to be directly involved in the somatic cell evolution process which is the basis of many common and complex diseases such as c...

Known genetic alterations play a major role in perturbing male reproductive health. We sought to retrospectively validate the European Association of Urology (EAU) guidelines for karyotype analysis (KA) in a homogenous cohort of 1168 White European men presenting for primary couple's infertility (noninterracial infertile couples only) and to develop a novel nomogram capable of predicting karyot...

We provide the first karyotype description of the agro-predatory ant species Megalomyrmex incisus Smith, 1947 (Myrmicinae, Formicidae), and chromosome counts of its host Mycetophylax conformis (Mayr, 1884) (Myrmicinae, Formicidae) from geographically distinct populations. Colonies of both species were sampled from coastal areas of Ilhéus, Bahia, Brazil, and transferred to the laboratory. Metaph...

The impact of abnormal placental karyotype on the inflammatory response within the villous tissue and peripheral circulation of women with miscarriage was evaluated. Villous (n = 38) and venous blood samples (n = 26) were obtained from women with missed miscarriage. Tissue chromosome analysis indicated 23 abnormal and 15 normal karyotypes. Concentration of tumour necrosis factor alpha (TNFα), T...

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

background and objectives: scapular stabilization and neuromuscular control provide an important parameter to characterize shoulder function during dynamic activities. many studies have confirmed the effect of the loading on scapular position and scapulohumeral rhythm. therefore, the evaluation of stabilizer muscles involvement in scapular asymmetry may assist in the development of clinical exa...

holding cash is a matter of managerial discretion. theaim of this paper is to contrast the effect of accruals quality on cashholding for a sample of 120 firms listed in the tehran stock exchangeduring 2001-2011.the results show that firms with good accruals quality hold lower cashlevels than firms with poor accruals quality. this result conform thefindings of teruel & solano (2009), which state...

introduction: analysis of smile is one of the esthetic evaluations in dentistry. in the present study, gla, lid, the long axis position and the oblique axial angle of each tooth were evaluated. materials and methods: in this cross-sectional analytical study, 80 subjects with properly-aligned teeth and healthy periodontium were selected. a digital camera was to take photos of lip areas in unifor...

The chromosomes of male and female individuals Enteromius callipterus [1] were assessed in this study with the objective determining diploid chromosome karyotype. samples obtained from Tahoss River, Jos Plateau, assessment was conducted using conventional Giemsa staining technique. reveals that individual E. has a number 2n = 50, fundamental autosomal arms (NFa) 82, karyotype formula 14M + 4m 3...

OBJECTIVE To determine the prevalence of chromosomal abnormalities and microdeletions on Y chromosome in infertile patients with oligozoospermia or azoospermia in Mato Grosso state, Brazil. METHODS This cross-sectional study enrolled 94 men from infertile couples. Karyotype analysis was performed by lymphocyte culture technique. DNA from each sample was extracted using non-enzymatic method. M...
