1. The effects of pulsatile and continuous intravenous administration of exogenous, pituitary-derived chicken growth hormone (p-cGH) on lipid metabolism and endocrine/metabolite levels of broiler-strain pullets were studied. 2. Eight-week-old pullets were administered p-cGH or vehicle over a 10 min period every 90 min for 7 days. 3. Pullets were also administered the same daily amount (123 micr...

Comparative genomic hybridization (CGH) was used to examine gains and losses in 18 meningioma tumors that had been previously analyzed for loss of heterozygosity (LOH) at 22q12. Partial or complete losses were seen by CGH in only 9 of 18 cases on chromosome 22. This compares with 11 of 18 losses of single or more loci by LOH. The discrepancy in these results in probably explained by the increas...

v High complexity of computer-generated holography (CGH) is already well known to researchers in the field of optical engineering. Therefore, in order to improve the practicability of CGH, it should be substantially reduced. In this paper, we proposed a method that can quickly generate digital video holograms using a spatiotemporal sampling scheme and general purpose graphic processing units (G...

Sex-dependent pituitary GH secretory profiles--pulsatile in males and persistent in females--regulate sex-biased, STAT5-dependent expression of hundreds of genes in mouse liver, imparting sex differences in hepatic drug/lipid metabolism and disease risk. Here we examine transcriptional and epigenetic changes induced by continuous-GH infusion (cGH) in male mice, which rapidly feminizes the tempo...

BACKGROUND Array Comparative Genomic Hybridization (array CGH) is increasingly applied on DNA obtained from formalin-fixed paraffin-embedded (FFPE) tissue, but in a proportion of cases this type of DNA is unsuitable. Due to the high experimental costs of array CGH and unreliable methods for DNA quality testing, better prediction methods are needed. The aim of this study was to accurately determ...

MOTIVATION Array-CGH can be used to determine DNA copy number, imbalances in which are a fundamental factor in the genesis and progression of tumors. The discovery of classes with similar patterns of array-CGH profiles therefore adds to our understanding of cancer and the treatment of patients. Various input data representations for array-CGH, dissimilarity measures between tumor samples and cl...

Comparative Genomic Hybridization (CGH), when combined with microarray technology, measures copy number alterations (gains or losses of DNA segments) of a large number of genomic intervals. Selecting a small number of discriminative intervals from these genomic intervals is an important problem, known as feature selection, for accurate classification of CGH data. An important aspect of CGH data...

BACKGROUND Comparative genomic hybridization (CGH) is a valuable alternative to fluorescence in situ hybridization (FISH) for preimplantation genetic screening (PGS) because it allows full karyotype analysis. However, this approach requires the cryopreservation of biopsied embryos until results are available. The aim of this study is to reduce the hybridization period of CGH, in order to make t...

It has been suggested that differential diagnosis of headaches should consist of a robust subjective examination and a detailed physical examination of the cervical spine. Cervicogenic headache (CGH) is a form of headache that involves referred pain from the neck. To our knowledge, no studies have summarized the reliability and diagnostic accuracy of physical examination tests for CGH. The aim ...

BACKGROUND AND OBJECTIVES The diagnosis of polycythemia vera (PV) is supported by the finding of an abnormal karyotype in patients with erythrocytosis. However, most PV patients have normal marrow cytogenetics at presentation and there is reluctance to use this test routinely. Comparative genomic hybridization (CGH) is a cytogenetic screening technique that analyzes interphase cells. This appro...
