Pseudomonas putida CA-3 has been shown to accumulate the biodegradable plastic polyhydroxyalkanoate (PHA) when fed styrene or polystyrene pyrolysis oil as the sole carbon and energy source under nitrogen limiting growth conditions (67 mg nitrogen per litre at time 0). Batch fermentation of P. putida CA-3 grown on styrene or polystyrene pyrolysis oil in a stirred tank reactor yields PHA at 30% o...

BACKGROUND The prognosis of hyperventilation syndrome (HVS) is generally good. However, it is important to proceed with care when treating HVS because cases of death following hyperventilation have been reported. This paper was done to demonstrate the clinical risk of post-hyperventilation apnea (PHA) in patients with HVS. CASE PRESENTATION We treated two patients with HVS who suffered from P...

The Brazilian National Policy on Dam Safety (PNSB) was enacted in 2010 and there are still many actions to be carried out, especially the classification of dams as associated hazard potential (PHA) risk category (RC). analysis conducted based Report 2020 informs that 21953 distributed throughout territory registered Information System (SNISB). However, 14849 (67.64%) were not classified RC 1347...

Biopolyesters polyhydroxyalkanoates (PHA) produced by many bacteria have been investigated by microbiologists, molecular biologists, biochemists, chemical engineers, chemists, polymer experts and medical researchers. PHA applications as bioplastics, fine chemicals, implant biomaterials, medicines and biofuels have been developed and are covered in this critical review. Companies have been estab...

The Pelger-Huët anomaly (PHA) is a recognized morphologic variant affecting all granulocytes but is most evident in polymorphonuclear neutrophils (PMNs). PHA is caused by a decreased amount of the lamin B receptor (LBR). Recognition of PHA morphologic features serves as a marker for mutations in the LBR gene. This review summarizes the history of PHA and the current knowledge of the functions o...

The Mediterranean diet is a healthy dietary pattern known to actively modulate the cell membrane properties. Phase angle (PhA) is a direct measure by Bioelectrical Impedance Analysis (BIA) used as marker of cell membrane integrity. Both food behaviour and PhA are influenced by age, sex and body weight. The aim of this study was to cross-sectionally evaluate the association between the adherence...

The histamine release induced by compound 48/80, bradykinin or polyethylenimine with a molecular weight of 600 (PEI6) was inhibited by wheat germ agglutinin (WGA) and phytohemagglutinin E-subunits (PHA-E4), and the inhibition was specifically reversed by N-acetyl glucosamine and N-acetyl galactosamine, respectively. Concanavalin A (Con A) and phytohemagglutinin L-subunits (PHA-L4) did not inhib...

Cotyledons of developing Phaseolus vulgaris L. cv Greensleeves seeds were labeled for 2 to 3 hours with (3)H-amino acids, and newly synthesized phytohemagglutinin (PHA) was isolated by affinity chromatography with thyroglobulin-Sepharose. The presence of 1% Tween in the homogenate increased the yield of radioactive PHA by 50 to 100%. Isopycnic sucrose gradients were used to show that this deter...

Polyhydroxyalkanoates (PHA) are biodegradable, thermoplastic polyesters produced from renewable carbon sources by a number of bacteria. However, their application is limited by high production costs. One of the strategies aimed to reduce their costs is the development of recombinant strains able to utilize different carbon sources. Many bacteria are naturally capable of accumulating biopolyeste...
