The binding of phytohemagglutinins from Phaseolus vulgaris (erythroagglutinating phytohemagglutinin (E-PHA) and leukoagglutinating phytohemagglutinin (L-PHA)) and from Lens culinaris (lentil-PHA) to human platelet cell surfaces has been demonstrated. Each platelet binds on an average 500,000 to 600,000 molecules of E-PHA with an apparent dissociation constant of 0.5 X 10m7 M. These values were ...

Recently, many economic studies of poly(3-hydroxybutyrate) PHB production on an industrial scale, and the impact of replacing petrochemical polymers by PHB were carried out, clearly indicating that the most crucial factors to reduce the cost of producing biopolymers are allotted to the application of microbial production strains capable of high productivi...

A number of Pseudomonas strains accumulated polyhdroxyalkanoate (PHA) from a variety of aromatic hydrocarbons. In many strains the level of PHA accumulation was dependent on the side chain length of the phenylalkanoic acid provided for growth. 4 of the 8 strains accumulated increased levels of PHA as the side chain length of the phenylalkanoic acid substrate increased. PHA accumulated from styr...

drilling industry provides a significant potential for occupational health risks. thus, health-related hazards (chemical, physical, ergonomic and biological) must be recognized, evaluated and controlled in order to prevent occupational illnesses which come from exposure to them. for these, a good occupational health risk assessment needs to be applied. risk assessment monitors risks and provide...

before giving any preliminary definition of “hazard” (calamity) and “hazardology”, it is important to notice that “who” is giving this definition, a geologist, a sociologist, an ethnologist, an expert in law, a religionologist, etc? certainly, each of these people has their own personal assumptions & presuppositions and so will look at the matter from a different point of view. also, there are ...

Although it is hard to predict wildfires, risky areas can be systematically assessed and managed. Some of the factors for decision-making are hazard, vulnerability, risk maps, which end product wildfire mapping. This study deals with analysis in Queensland, Australia. A review previous studies focusing on each aspect has been done used records from 2011 2019 Australia, compile required input mo...

The activity of α-1,2-mannosidase I is required for the conversion of high-mannose to hybrid-type (ConA reactive) and complex-type N-glycans (Phaseolus vulgaris-leukoagglutinin [PHA-L] reactive) during posttranslational protein N-glycosylation. We recently demonstrated that α-1,2-mannosidase I mRNA decreases in graft-infiltrating CD11c(+) dendritic cells (DCs) prior to allograft rejection. Alth...

Phytohemagglutinin (PHA), the major seed lectin of the common bean, Phaseolus vulgaris, accumulates in the parenchyma cells of the cotyledons. It has been previously shown that PHA is cotranslationally inserted into the endoplasmic reticulum with cleavage of the NH2-terminal signal peptide. Two N-linked oligosaccharide side chains are added, one of which is modified to a complex type in the Gol...
