An overview is provided of recent developments in the use of latent class (LC) and other types of %nite mixture models for classi%cation purposes. Several extensions of existing models are presented. Two basic types of LC models for classi%cation are de%ned: supervised and unsupervised structures. Their most important special cases are presented and illustrated with an empirical example. c © 20...

Along with the creation of new maps, current efforts for improving global land cover (GLC) maps focus on integrating maps by accounting for their relative merits, e.g., agreement amongst maps or map accuracy. Such integration efforts may benefit from the use of multiple GLC reference datasets. Using available reference datasets, this study assesses spatial accuracy of recent GLC maps and compar...

In this month’s “Column Watch,” Ron Majors discusses advances in multidimensional chromatography and comprehensive multidimensional chromatography. These techniques are well suited for the separation of complex samples. Although GC GC is fairly well developed, LC LC is in its infancy. But with fast LC columns, based on monoliths, superficially porous particles, and short sub-2m particle columns...

abstract background: “polycystic ovary syndrome (pcos) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction”. “autonomic and central nervous systems play important roles in the regulation of ovarian physiology”. the noradrenergic nucleus locus coeruleus (lc) plays a central role in the regulation of the sympathetic nervous system and synaptically connected to the ...

Objective Chemotherapy may damage ovaries. L-carnitine (LC) as a type of flavonoid antioxidants and bone marrow stromal cells (BMSCs) as a type of mesenchymal stem cells may recover damaged ovaries. It seems that LC has favorable effects on differentiation, increasing lifespan and decreasing apoptosis in BMSCs. The aim of this study was to investigate the effects of co-administration of BMSCs a...

results mean operative time was shortest in group a (57.1 minutes) and longest in group b [63.4 (p = 0.131)]. mean hospital stay was shortest in group a (2.1 days) and longest in group c (5.7 days) (p = 0.003). hospital expenses were minimal in group a (p = 0.001). male sex, serum bilirubin level, white blood cell (wbc) count, duration of ercp/es procedure, contracted gall bladder and large cal...

Background: The glycoconjugate content of sperms indicates their physiological and fertility properties. Lectin reactivity is indicative of intact, capacitated, and acrosome-reacted sperms. In the epididymis, sperms experience maturation, glycoconjugate modification, and simultaneously, higher L-carnitine (LC) concentrations. The aim of this project was to evaluate the effects of LC and Pentoxi...
