Primary hepatic angiosarcoma (PHA) is an exceedingly rare and aggressive neoplasm of mesenchymal origin. PHA makes a very small portion primary liver tumors conveys poor prognosis. Symptomatology can be vague often mimics hepatocellular carcinoma upon presentation. Diagnosis requires careful immunohistopathologic confirmation. We present case in patient with abdominal pain suspected underlying ...

Polyhydroxyalkanoates (PHAs) are synthesized and assembled as PHA granules that undergo well-regulated formation in many microorganisms. However, this regulation remains unclear in haloarchaea. In this study, we identified a PHA granule-associated regulator (PhaR) that negatively regulates the expression of both its own gene and the granule structural gene phaP in the same operon (phaRP) in Hal...

The use of molecular diagnostic techniques for bioprospecting and microbial diversity study purposes has gained more attention thanks to their functionality, low cost and quick results. In this context, ten degenerate primers were designed for the amplification of polyhydroxyalkanoate synthase (phaC) gene, which is involved in the production of polyhydroxyalkanoate (PHA)-a biodegradable, renewa...

The current problems with decreasing fossile resources and increasing environmental pollution by petrochemical-based plastics have stimulated investigations to find biosynthetic materials which are also biodegradable. Bacterial reserve materials such as polyhydroxyalkanoates (PHA) have been discovered to possess thermoplastic properties and can be synthesized from renewable resources. Poly-beta...

Anaerobic sludge digestion is the main technology for sludge reduction and stabilization prior to sludge disposal. Nevertheless, methane production from anaerobic digestion of waste activated sludge (WAS) is often restricted by the poor biochemical methane potential and slow hydrolysis rate of WAS. This work systematically investigated the effect of PHA levels of WAS on anaerobic methane produc...

INTRODUCTION Progressive hemifacial atrophy (PHA) is a rare disorder characterized by unilateral facial atrophy affecting the skin, subcutaneous tissue, and fat, muscle, and osteocartilagenous structures creating a sunken hemiface appearance.Etiopathogenesis of PHA is poorly understood; no definitive treatment is currently available. CLINICAL FINDINGS We report a 41-year-old woman with PHA wh...

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...
