The goal of this study was to evaluate the potential relationship among polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and rheumatoid arthritis (RA) susceptibility as well as the association among the polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and their expression.We performed a hospital-based, case-control ...

In many animal species, the propensity for aggression is linked to social context. In social insects, aggressive interactions between colonies are related to the assessment of cuticular hydrocarbon profiles. We investigated how, in the red harvester ant, Pogonomyrmex barbatus, an individual ant's task environment contributes to its hydrocarbon profile, and how task-specific differences in profi...

The quality of wide a variety of synthetic or naturally occurring materials which are used for outdoor applications are known to be adversely affected by environmental factors. These materials absorb solar ultraviolet radiation leading to changes in their structures and compositions. The consequences of these changes lead to degradation of the materials. Bitumen is one of the materials which is...

This case report describes a patient with Swyer-James-MacLeod Syndrome (SJMS) in an adult male diagnosed on the basis of findings on X-ray chest, high resolution CT (HRCT) of chest and radionuclide perfusion lung scan. This rare syndrome is considered to be an acquired disease due to repeated pneumonias in early childhood.

Bacterial pathogens are responsible for the most severe forms of pneumonia, bronchitis and other respiratory tract infections (RTI), which have high morbidity and mortality rates especially among the elderly and children under 5 years [1]. Streptococcus pneumoniae accounts for the majority of community-acquired bacterial pneumonias and is also capable of causing meningitis, otitis media, and ot...

Viral bacterial coinfections are encountered in about one third of community aquired pneumonia cases in children. There is however very difficult to differentiate pneumonias ́ etiology using clinical, laboratory and radiological examination. We present a case of viral-bacterial coinfections and the challegences that this case imposed in both diagnostic and treatment decision. We shall also revie...

based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...
