Various chromosomal banding techniques were utilized on the catfish, Iheringichthys labrosus, taken from the Capivara Reservoir. C-banding regions were evidenced in telomeric regions of most of the chromosomes. The B microchromosome appeared totally heterochromatic. The restriction endonuclease AluI produced a banding pattern similar to C-banding in some chromosomes; the B microchromosome, when...

T he technique of cementing orthodontic bands to teeth was first introduced by Magil I in 1871 and remained the treatment of choice for more than 85 years. Direct bonding has replaced anterior teeth banding and offers significant advantages such as improved esthetics, ease of placement, patient comfort, decreased soft tissue irritation, enhanced ability to detect interproximal decay, and less d...

In this study, the BOX-PCR fingerprinting technique was evaluated for the discrimination of clinical Pseudomonas aeruginosa isolates. All isolates were typeable and nearly half showed unique banding patterns. According to our results, BOX-PCR fingerprinting is applicable for typing of Pseudomonas aeruginosa isolates and can be considered a useful complementary tool for epidemiological studies o...

abnormalities [1-3]. Fluorescence in situ hybridization (FISH) analysis was carried out using TUPLE region probe (from Kreatech Diagnostics, Netherland) on metaphase and interphase cells. Presence of two intact signals on chromosome 22 ruled out 22q11.2 deletion. Thus, chromosomal analysis was carried out using the GTG-banding technique and the patient was found to be tetrasomy for sex chromoso...

The objective of this study was to design DNA probe sets that enable the detection of chromosome aberrations in acute myeloid leukemia (AML) by interphase cytogenetics using fluorescence in situ hybridization (FISH) and to compare the results of interphase cytogenetics with those of conventional chromosome banding analysis. One hundred five consecutive patients with adult AML entered on a multi...
