Leishmania promastigotes express several prominent glycoconjugates, either secreted or anchored to the parasite surface. Of these lipophosphoglycan (LPG) is the most abundant, and along with other phosphoglycan-bearing molecules, plays important roles in parasite infectivity and pathogenesis in both the sand fly and the mammalian host. Besides its contribution for parasite survival in the sand ...

Alkane hydrocarbons (propane, isobutane, and n-butane) from liquefied petroleum gas (LPG) are present in major quantities throughout Mexico City air because of leakage of the unburned gas from numerous urban sources. These hydrocarbons, together with olefinic minor LPG components, furnish substantial amounts of hydroxyl radical reactivity, a major precursor to formation of the ozone component o...

Temperature distribution is a critical indicator of the health condition for Liquefied Petroleum Gas (LPG) storage tanks. In this paper, we present a large-scale wireless temperature monitoring system to evaluate the safety of LPG storage tanks. The system includes wireless sensors networks, high temperature fiber-optic sensors, and monitoring software. Finally, a case study on real-world LPG s...

Lipophosphoglycan (LPG) is the predominant surface glycoconjugate of Leishmania promastigotes and plays several roles in the infectious cycle of this protozoan parasite. The salient feature of LPG is the presence of 15–30 copies of a disaccharide-phosphate repeating unit Gal(b1,4)Man(a1-PO4), which is also found on many other secreted molecules (secretory acid phosphatase, phosphoglycan, proteo...

Gas stoves are now very common in all houses including urban and remote areas. The main power source for gas stoves are either LPG or biogas. Biogas is more cost effective compared to LPG. In both cases chemical energy stored in the fuel is converted into heat energy and this heat energy is used for cooking purpose. Explosive range of LPG is 1.8%-9.5% volume of gas in air. Biogas mainly contain...

Liquefied petroleum gas (LPG) is widely used in the Gaza Strip for domestic purposes, in agriculture and industry and, illegally, in cars. This study aimed to identify possible health effects on workers exposed to LPG in Gaza governorates. Data were collected by a questionnaire interview, and haematological and biochemical analyses of venous blood samples were made from 30 workers at filling an...

Antibiotics that inhibit the biosynthesis of the cell wall, such as vancomycin, penicillin, d-cycloserine, and bacitracin, stimulate the incorporation of lysine into lipids that are extractable with n-butanol-6 M pyridinium acetate. Approximately 93% of this lysine is in lysylphosphatidylglycerol (LPG). The remaining lysine is incorporated in another as yet uncharacterized lipid. Because the ly...

In this study on-road gaseous emissions of vehicles are investigated using remote sensing measurements collected over three different periods. The results show that a high percentage of gaseous pollutants were emitted from a small percentage of vehicles. Liquified Petroleum Gas (LPG) vehicles generally have higher gaseous emissions compared to other vehicles, particularly among higher-emitting ...

The most abundant surface macromolecule on the promastigote stage of leishmanial parasites is a polymorphic lipophosphoglycan (LPG). We have elucidated the structures of two new LPGs, from Leishmania tropica (LRC-L36) and L. aethiopica (LRC-L495), and investigated the nature of intra-specific polymorphism in the previously characterized LPG of L. major (LRC-L456 and -L580). These molecules cont...
