Eighteen patients with acute lymphoblastic leukemia (ALL) were investigated using spectral karyotyping (SKY), and multicolor fluorescence in situ hybridization (FISH) banding analyses. SKY analysis confirmed previous results in patients with G-banded diploid karyotype. Nevertheless in three out of five patients with two or more chromosomal abnormalities, SKY and multicolor banding methods refin...

The application of staining with the guanine-cytosine specific fluorochrome chromomycin A3 (CMA) of citrus chromosomes to genetic studies is reviewed. When CMA staining is performed, the existence of characteristic CMA banding patterns with high levels of diversity and heterozygosity in citrus chromosomes is demonstrated. Similar CMA banding patterns have been observed in related species. Thus,...

BACKGROUND Bariatric surgery is expanding to meet the global epidemic of morbid obesity, because this surgery is successful in achieving sustained weight loss. After having recently established a rat model of gastric banding, our aim now was to investigate the relative fat mass content and the feeding patterns of gastric banded rats. METHODS Two groups of Wistar rats, submitted either to gast...

Balanced steady-state free precession (SSFP) is hindered by the inherent off-resonance sensitivity and unwanted bright fat signal. Multiple-acquisition SSFP combination methods, where multiple datasets with different fixed RF phase increments are acquired, have been used for shaping the SSFP spectrum to solve both problems. We present a new combination method (weighted-combination SSFP or WC-SS...

BACKGROUND The use of bariatric surgery in the management of morbid obesity is rapidly increasing. The two most frequently performed procedures are laparoscopic Roux-en-Y bypass and laparoscopic gastric banding. The objective of this short overview is to provide a critical appraisal of the most relevant scientific evidence comparing laparoscopic gastric banding versus laparoscopic Roux-en-Y byp...

We perform a quantitative textural analysis of banding in obsidian from Big Glass Mountain (BGM), Medicine Lake Volcano, California and from Mayor Island (MI), New Zealand. The samples are compositionally homogeneous, with banding defined by variable microlite content (BGM) or vesicularity (MI). The spatial distribution of alternating light and dark bands has a 1/wavenumber power-spectral densi...

Yeasts are eukaryotic microorganisms including 1,500 species. They are an important model organism in modern cell biology research, and are one of the most thoroughly researched eukaryotic microorganisms. Some yeast can find potential application in the field of bioremediation. In the present investigation the yeast samples were isolated on YPD medium from natural sources like ripened fruits, m...
