SYNOPSIS. I review recent advances in our knowledge of the eucaryotic cell cycle: the set of processes by which cells grow and divide. Genetic approaches to the cell cycle of somatic cells identified a pathway of events where the initiation of each event was dependent on the successful completion of the preceding event, as well as a single key gene, cdc2, that is required both at the beginning ...

BACKGROUND Evaluate and compare the utility of serum folate receptor alpha (FRA) and megakaryocyte potentiating factor (MPF) determinations relative to serum CA125, mesothelin (MSLN) and HE4 for the diagnosis of epithelial ovarian cancer (EOC). METHODS Electrochemiluminescent assays were developed for FRA, MSLN and MPF and used to assess the levels of these biomarkers in 258 serum samples fro...

G2-arrested oocytes contain cdc2 kinase as an inactive cyclin B-cdc2 complex. When a small amount of highly purified and active cdc2 kinase, prepared from starfish oocytes at first meiotic metaphase, is microinjected into Xenopus oocytes, it induces activation of the inactive endogenous complex and, as a consequence, drives the recipient oocytes into M phase. In contrast, the microinjected kina...

The purpose of this study was to identify the attenuating influence on surface-EMG amplitude (IEMG) and mean power frequency (MPF) by skin and subcutaneous fat tissue. The electrode-muscle-distance (∆EM) of the left m. biceps brachii is determined by tissue thickness. This was established by ultrasound in 12 females and 15 males six times each during a 43-week period (n=162). IEMG and MPF were ...

The resumption of meiosis in Xenopus arrested oocytes is triggered by progesterone, which leads to polyadenylation and translation of Mos mRNA, then activation of MAPK pathway. While Mos protein kinase has been reported to be essential for re-entry into meiosis in Xenopus, arrested oocytes can undergo germinal vesicle breakdown (GVBD) independently of MAPK activation, leading us to question wha...

The induction of oocyte maturation is known to involve an initial action of agonists at the oocyte surface. This leads to activation of a cytoplasmic maturation-promoting factor (MPF) which induces the observable events associated with maturation (reviews by Smith and Ecker, 1970; Smith, 1975; Wasserman and Smith, 19786; Baulieu et al. 1978; Masui and Clark, 1979; Mailer and Krebs, 1980; Mailer...

This paper describes a new packet filter mechanism that efficiently dispatches incoming network packets to one of multiple endpoints, for example address spaces. Earlier packet filter systems iteratively applied each installed filter against every incoming packet, resulting in high processing overhead whenever multiple filters existed. Our new packetfilter provides an associative match function...

Soil erosion is a potentially important source of microplastic (MP) entering aquatic ecosystems. However, little known regarding the and transport processes MP from agricultural topsoils. The aim this study to analyze behavior during heavy rainfall events, whereas specific focus set preferential MP-soil interactions leading more conservative behavior. based on series simulations paired-plots (4...

This article’s main goal is to investigate the concept of multi-polar fuzzy sets (MPF-sets) in LA-semi-groups, which an extension bi-polar (BPF-sets) LA-semigroups. The objective this research extend certain significant BPF-set results MPF-sets results. article introduces concepts sub LA-semigroups, quasi-ideals, bi-ideals, generalized and interior ideals also discusses a number fundamental asp...

Global changes such as increasing CO2, rising temperature, and land-use change are likely to drive shifts in litter inputs to forest floors, but the effects of such changes on litter decomposition remain largely unknown. We initiated a litter manipulation experiment to test the response of litter decomposition to litter removal/addition in three successional forests in southern China, namely ma...
