small supernumerary marker chromosomes (ssmc) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. on the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo ...

Methods Using dual–energy X ray absorptiometry and bone metabolism markers (bone formation marker; BAP, bone resorption marker; TRAP5b), the bone mineral density of lumbar and bilateral proximal femurs were studied in 41 AIS patients aged 10 to 20 years old, with a mean of 15.2±5.9 years old. Divided into two groups by levels of bone resorption marker (TRAP5b), BMD, BMI and age of menarche were...

Ia antigens and two different types of complement (C) receptors appeared on membrane surfaces in a distinct sequence during the maturation of human neutrophils. Taking advantage of the finding that neutrophil celll density increased with maturation, density gradient centrifugation was used to separate neutrophils into fractions that were greatly enriched in cells representing individual stages ...

background spirulina is one of the most profitable known microalgae in the world, which is used as food and superfood. in the other hand, spirulina is a useful source of healthy components. it seems that the spirulina is transformable so that the introduction of a selectable marker is needed. objectives the purpose of this study was to determine a suitable selection marker for spirulina platens...
