OBJECTIVE To determine if the primary method of cytogenetic analysis in pregnant women undergoing amniocentesis should be quantitative fluorescent polymerase chain reaction (qf-PCR), with karyotyping being performed only on those with abnormal ultrasound findings. METHODS Amniocentesis was performed in 3854 cases. The median maternal age was 36 years and median gestational age was 18 weeks. T...

The aim of this study was to investigate the myogenic factor mRNA expression pattern of Pax7, Myf5, MyoG, and Myostatin mRNA at different ages, sexes, and muscle tissues of Datong yaks. The expression patterns in semimembranosus (SM), quadriceps femoris (QF), and triceps muscle of arm (TM) were detected by quantitative real-time polymerase chain reaction and compared using biostatistics. The re...

OBJECTIVES To report our experience over the past 10 years of chorionic villi sampling (CVS) prenatal diagnosis in a high-risk population for chromosomal anomalies, and to analyze, according to the results, the advantages and disadvantages of using quantitative fluorescence polymerase chain reaction (QF-PCR) in amniotic fluid with respect to a conventional semi-direct cytogenetic CVS method in ...

OBJECTIVE G-Banding followed by standard chromosome analysis is routinely used for prenatal detection of chromosomal abnormalities. In recent years, molecular cytogenetic techniques have been developed for rapid diagnosis of chromosomal abnormalities. Among these methods Quantitative Florescence Polymerase Chain Reaction (QF-PCR) has been widely used for this purpose. Heterozygosity of short ta...

For each vertex s of the vertex subset S of a simple graph G, we define Boolean variables p = p(s, S), q = q(s, S) and r = r(s, S) which measure existence of three kinds of S-private neighbours (S-pns) of s. A 3-variable Boolean function f = f(p, q, r) may be considered as a compound existence property of S-pns. The subset S is called an f -set of G if f = 1 for all s ∈ S and the class of f -se...

Gram-negative pathogen-induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan (QF), a traditional Chinese medicine (TCM) formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa-ind...

In the process of car body design, various surfaces can be generated,from the given boundary curves. Depending tqon the method qf the surface generation and the qualip qf the boundary curves provided, the resulting surfaces may have global 07” local irregularities in many cases. Thus it would be necessarvfor the designer to evaluate the surface quality and to rnodifi the surface or to use the d...

One reason for the universal interest in Frobenius algebras is that their characterisation can be formulated in arbitrary categories: a functor K : A → B between categories is Frobenius if there exists a functor G : B → A which is at the same time a right and left adjoint of K; a monad F on A is a Frobenius monad provided the forgetful functor AF → A is a Frobenius functor, where AF denotes the...
