polyhydroxyalkanoates (phas) is known to be temporarily stored by microorganisms in activated sludge, especially in the anaerobic-aerobic processes. the main objective of this study was to investigate the effects of fatty acids (vfas) compounds coexistence in substrate of sbr on phas productivity of activated sludge. it has been found that addition of different concentrations of vfas results in...

The -phaseolin (phas) gene, which encodes one of the major seed storage proteins of P. vulgaris, is tightly regulated at the transcription level resulting in strict tissuespecific and spatial expression during embryonic development. The phas proximal promoter contains a complex arrangement of core promoter elements including three TATA boxes as well as several putative initiator elements. To de...

OBJECTIVE To establish whether the finding of perihepatic adhesions (PHAs) at laparoscopy for ectopic pregnancy (EP) is associated with poor perioperative and reproductive outcomes. METHODS A retrospective cohort study was undertaken of all cases of EP managed surgically at a teaching hospital in northeast London in 2003-2013. Data for symptoms, reproductive history, ultrasonography findings,...

Biosynthesis of biodegradable polymers polyhydroxyalkanotes (PHAs) have been studied extensively in wild type and genetically modified prokaryotic cells, however the content and structure of PHAs in wild type yeasts is not well documented. The purpose of this study was to screen yeast isolates collected from different ecosystems for their ability to accumulate PHAs. Identification of the isolat...

In a BGP prefix hijacking event, a router originates a route to a prefix, but does not provide data delivery to the actual prefix. Prefix hijacking events have been widely reported and are a serious problem in the Internet. This paper presents a new Prefix Hijack Alert System (PHAS). PHAS is a real-time notification system that alerts prefix owners when their BGP origin changes. By providing re...

The primary site in PHAS-I for phosphorylation by protein kinase CK2 in vitro was identified as Ser111. A relatively small amount of phosphorylation of Ser99 was also detected, and mutating Ser99 to Ala in PHAS-I slightly decreased phosphorylation by CK2 in vitro. In contrast, mutating Ser111 to Ala almost abolished phosphorylation, confirming Ser111 as the preferred site for CK2. Phosphorylati...

This study compared the PHAs production behavior of sludges from the anaerobic and oxic phases of an enhanced biological phosphorus removal (EBPR) system. This was accomplished by using the kinetics and stoichiometric coefficients obtained from aerobic batch tests to evaluate the performance of these two sludges. Experimental results indicated that the metabolic behavior of the sludges for PHAs...

Phased small interfering RNA (phasiRNA) generating loci (briefly as PHAS) in plants are a novel class of genes that are normally regulated by microRNAs (miRNAs). Similar to miRNAs, phasiRNAs encoded by PHAS play important regulatory roles by targeting protein coding transcripts in plant species. We performed a genome-wide discovery of PHAS loci in Chinese sacred lotus and identified a total of ...

The beta-phaseolin (phas) gene, which encodes one of the major seed storage proteins of P. vulgaris, is tightly regulated at the transcription level resulting in strict tissue-specific and spatial expression during embryonic development. The phas proximal promoter contains a complex arrangement of core promoter elements including three TATA boxes as well as several putative initiator elements. ...
