BACKGROUND & AIMS This study determined the association between phase angle (PhA), by bioelectrical impedance analysis (BIA) and nutritional risk by Nutritional Risk Screening (NRS-2002), Subjective Global Assessment (SGA), hospital length of stay (LOS) and 30 day non-survival in patients at hospital admission compared to healthy controls. METHODS PhA was determined by BIA in patients (n = 98...

BACKGROUND Achieving a sustainable society requires, among other things, the use of renewable feedstocks to replace chemicals obtained from petroleum-derived compounds. Crude glycerol synthesized inexpensively as a byproduct of biodiesel production is currently considered a waste product, which can potentially be converted into value-added compounds by bacterial fermentation. This study aimed a...

Among all types of biopolymers occurring in living cells, poly(hydroxyalkanoates) (PHAs) display the highest potential for applications in diverse fields of the plastic market.1,2,3,4 PHAs are biobased, biocompatible and biodegradable polyesters of hydroxyalkanoic acids synthesized by prokaryotic microbes as intracellular carbon and energy storage compounds.5,6 Additionally, PHA synthesis by ge...

Polyhydroxyalkanoates (PHA), an intracellular energy and carbon storage polymer, can be accumulated in activated sludge in substantial quantities under wastewater dynamic treatment (i.e., substrate feast-famine) conditions. However, its influence on hydrogen production has never been investigated before. This study therefore evaluated the influences of PHA level and composition in waste activat...

We have examined the effect of progranulin (PGRN) on human T cell proliferation and its underlying mechanism. We show that PGRN inhibits the PHA-induced multiplication of T lymphocytes. It increases the number of iTregs when T lymphocytes are activated by PHA but does not do so in the absence of PHA. PGRN-mediated inhibition of T lymphocyte proliferation, as well as the induction of iTregs, was...

The response to intradermally injected phytohaemagglutinin (PHA-response) is a commonly used quantification of avian immunocompetence (the ability to resist pathogens). Parasite-mediated sexual selection requires heritable immunocompetence, but evidence for heritability of PHA-response in birds largely stems from full-sib comparisons. Using an animal model approach, we quantified the narrow-sen...

Single or repetitive i.p. injections of Phytohemagglutinin (PHA) induced a selective marked decrease in blood and bone marrow lymphocytes in mice, suggesting that PHA might have a specific immunosuppressive effect. To test this hypothesis, parallel' experiments were conducted using female C57Bl/6J (H-2b) mice as recipients and either female C3H/HeJ (H-2k) or female (C57Blx C3He) Fl (H-2b,k) hyb...

This semester brought about great change to the Android PHA application and frenzied development. It is important to note that Android has a steep learning curve, and it took considerable time to learn the Android SDK and how to create an Android application properly. While Google provides some detailed instructions and tutorials on their developer zone website, complete resources are hard to c...

Abstract. Introduction. Polyhydroxyalkanoate (PHA) is a useful, carbon-neutral polymer that can be produced from renewable carbon sources by microorganisms, making it sustainable and environmentally friendly material. Currently, production of the biopolymer not competitive in terms cost yield; however, different bacterial strains may provide economic viability, especially since substituting bio...

A novel approach to the recycling of polystyrene is reported here; polystyrene is converted to a biodegradable plastic, namely polyhydroxyalkanoate (PHA). This unique combinatorial approach involves the pyrolysis of polystyrene to styrene oil, followed by the bacterial conversion of the styrene oil to PHA by Pseudomonas putida CA-3 (NCIMB 41162). The pyrolysis (520 degrees C) of polystyrene in ...
