Coastal salt marshes are highly sensitive wetland ecosystems that can sustain long-term impacts from anthropogenic events such as oil spills. In this study, we examined the microbial communities of a Gulf of Mexico coastal salt marsh during and after the influx of petroleum hydrocarbons following the Deepwater Horizon oil spill. Total hydrocarbon concentrations in salt marsh sediments were high...
Biodegradation of a model mixture of hydrocarbon (dodecane and hexadecane, 1:1 w/w), as well as hydrocarbon emulsified by synthetic and natural emulsifiers, and their mixtures were analyzed in the presence of Pseudomonas spp. and Bacillus spp. bacterial strains. Changes in surface tension were measured by the static and dynamic methods during biodegradation processes. During the biodegradation ...
Adult epicuticular hydrocarbon variation of 14 geographically isolated populations of cactophilic Drosophila mojavensis was assessed to further investigate mechanisms of sexual isolation. Hydrocarbon transfer experiments demonstrated that these compounds are part of the mate recognition system in this species. Sixteen of the 23 epicuticular hydrocarbon components studied differed in amounts bet...
Traditionally, a subset of patients diagnosed as having idiopathic pulmonary fibrosis had positive results on cellular biopsies (prominent lymphoplasmacytic inflammation), bronchoalveolar lavage lymphocytosis, a clinical response to steroids, and a better long-term prognosis. On review of the lung histopathology, the lesion was characterized by varying degrees of inflammation and fibrosis. This...
Common variable immune deficiency (CVID) is a syndrome which is due to deficiency of humoral immune response resulting in increased susceptibility to infections We report a case of CVID in a 24-year-old male whopresented with a history of recurrent pneumonias.
Most children presenting with pneumonia in the industrialised world will have a viral or 'atypical' organism. The clinical features of these 'atypical' pneumonias may be indistinguishable from bacterial pneumonia. New diagnostic techniques such as the polymerase chain reaction may help in diagnosis and choice of treatment, where appropriate. The pathological and clinical features of infection w...
