Background: Acetaldehyde, a natural by-product of combustion and photo-oxidation, has been detected at low levels in cigarette smoke. Various literature studies have shown increased salivary acetaldehyde production among smokers and heavy drinkers.
Aim: The present investigation was performed to estimate the salivary and serum acetaldehyde levels in pan masala chewers (with or without tobacco), betel quid chewers and tobacco smokers.
In this present research, we succeeded in synthesizing nanostructured silver particles (NS-AgPs) using bio active agent present in the leaf extracts of Cleome gynandra (CG) under green synthesis. While adding silver nitrate (AgNO) solution in green extracts of CG leaf containing bio compound, the mixture turns from yellow to reddish brown, as a consequence of existence of nanostructured silver particles (NS-AgPs) and later UV instrument is used to obtain the Ultraviolet visible spectroscopy (UV-vis) spectra to confirm existing nanostructured silver particles (NS-AgPs) in aqueous solutions (synthesized sample). To confirm existing functional groups in NS-AgPs, the fourier transform infrared spectroscopy (FTIR) study is carried throughout this research.

Micro RNAs (miRNAs) are known to control biological processes and are also involved in the initiation and progression of numerous cancers. The aim of this study was to identify small molecule inhibitors using bioinformatics methods for over-expressed miRNAs that are known to play a major role in the genesis of gastric cancer.

Risk factors for gastric cancer includes Helicobacter pylori infection, gastric ulcer, less hygienic condition, use of tobacco, alcohol consumption, use of salted, smoked food, genetic alterations etc. In order to identify the risk factors associated with gastric cancer in South Indian population a case-control study involving 200 proven gastric cancer cases and 400 controls was conducted.
