Prevention of Lung Cancer: Future Perspective with Natural Compounds
Brandes, Johann C.,Amin, A.R.M. Ruhul,Khuri, Fadlo,Shin, Dong-Moon The Korean Academy of Tuberculosis and Respiratory 2010 Tuberculosis and Respiratory Diseases Vol.69 No.1
Lung cancer remains the most common cause of cancer death in the United States and worldwide. About 80~90% of cases are smoking-related and smoking cessation programs are of great importance in reducing lung cancer risk. However, the lifetime risk for lung cancer remains elevated even in ex-smokers. Chemoprevention holds the promise to further reduce this risk and thus to decrease lung cancer incidence and mortality. Over the last decades, most chemoprevention trials for lung cancer have yielded negative outcomes. Population-based studies suggest that high intake of certain foods such as soy, red wine or green vegetables may be associated with decreased cancer risk. Because of these observations and their general safety, a plethora of natural compounds is currently being studied for the chemoprevention of cancer. In this review we discuss promising in vitro and in vivo data of novel natural compounds, their interference with molecular mechanisms responsible for lung cancer development and potential implications for their further preclinical and clinical investigation.

WATER VAPOR MASERS: A SIGNPOST FOR LOW MASS STAR FORMATION
Migenes, V.,Trinidad, M.A.,Valdettaro, R.,Brand, J.,Palla, F. The Korean Astronomical Society 2007 Journal of The Korean Astronomical Society Vol.40 No.4
It is well known that water vapor maser emission at 22.2 GHz is associated with the earliest stages of both low- and high-mass star formation and it can be considered a reliable diagnostic of their evolutionary state. Bright Rimmed Clouds (BRCs) are clouds that have been compressed by an external ionization-shock front which focuses the neutral gas into compact globules. The boundary layer between the neutral gas and the gas ionized by the incident photons is often called "bright rim" but the clumps are sometimes classified also as speck globules or cometary globules depending on their appearance. Small globules with bright rims have been considered to be potential sites of star formation and have been studied in several individual regions. We present results from high resolution VLA observations searching for new candidates of recent star formation in bright-rimmed clouds/globules associated with IRAS point sources.
