Airway Resistance Caused by Sphingomyelin Synthase 2 Insufficiency in Response to Cigarette Smoke.

Gayatri Gupta, Nathalie Baumlin, Justin Poon, Begum Ahmed, Yeun-Po Chiang, Christopher Railwah, Michael D Kim, Melissa Rivas, Hannah Goldenberg, Ziyad Elgamal, Matthias Salathe, Apurav A Panwala, Abdoulaye Dabo, Chongmin Huan, Robert Foronjy, Xian-Cheng Jiang, Raj Wadgaonkar, Patrick Geraghty,

Sphingomyelin synthase is responsible for the production of sphingomyelin (SGM), the second most abundant phospholipid in mammalian plasma, from ceramide, a major sphingolipid. Knowledge of the effects of cigarette smoke on SGM production is limited. In the present study, we examined the effect of chronic cigarette smoke on sphingomyelin synthase ... Read more >>

Assessment of Bronchiectasis in HIV Patients among an Urban Population.

Veena Dronamraju, Navneet Singh, Justin Poon, Sachi Shah, Joseph Gorga, Hector Ojeda-Martinez, Samy McFarlane,

Bronchiectasis is characterized by permanent destruction of the airways that presents with productive cough, as well as bronchial wall thickening and luminal dilatation on computed tomographic (CT) scan of the chest; it is associated with high mortality. Accumulating data suggests higher rates of bronchiectasis among the HIV-positive population. This case ... Read more >>

Chronic Cigarette Smoke Exposure Subdues PP2A Activity by Enhancing Expression of the Oncogene CIP2A.

Sridesh Nath, Michael Ohlmeyer, Matthias A Salathe, Justin Poon, Nathalie Baumlin, Robert F Foronjy, Patrick Geraghty,

Phosphatase activity of the major serine threonine phosphatase, protein phosphatase 2A (PP2A), is blunted in the airways of individuals with chronic obstructive pulmonary disease (COPD), which results in heightened inflammation and proteolytic responses. The objective of this study was to investigate how PP2A activity is modulated in COPD airways. PP2A ... Read more >>

Spontaneous pneumothorax as a complication of chronic Jet propulsion fuel-8 exposure.

Justin Poon, Moh'd Al-Halawani, Gangacharan Dubey,

Jet Propulsion Fuel 8 (JP-8) is a kerosene based fuel commonly used in aviation. Occupational exposure to JP-8 may lead to negative health outcomes, which were described in a small number of studies. We report a case of 33-year-old Caucasian male veteran with a history of JP-8 exposure who presented ... Read more >>
