  • Lavender oil is a prolonged history in ancient medicine and has a wide range of biological effects. The lavender essential oil has 50 different constituents that have different therapeutic significance. The compounds that are separated from essential oil can be used for the anticancer treatment of non-small cell lung cancer. ROS1 is one of the major targets for NSCLC. The compounds from lavender essential oil are separated through GC-MS. From 91 compounds the top compounds that are having high retention values are taken for Molecular docking study against the ROS1 target protein. The binding affinity and the docked pose for those compounds are studied. Later, the chemical reactivity of the compounds is studied by Density Functional Theory. The potent compounds must be validated by in vivo study.

  • Many attempts have been made to find genetic abnormalities inducing carcinogenesis after the development of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor targeting EGFR in lung cancer. New target therapies have been already commercialized and studied along with the recent discovery of gene rearrangement involved in the carcinogenic process of non-small cell lung cancer. This study aims to investigate anplastic lymphoma kinase, c-ros oncogene 1, and receptor tyrosine kinase, in particular.

  • The polysaccharide fraction from Taraxii Herba showed potent immunopotentiating activities with antitumor activities. The fraction having small amount of protein inhibited the growth of solid tumor and increased peritoneal exudate cells and immunoorgan weights in normal mice, and also increased hypersensitivities in tumor bearing mice.

  • A nanopore is a very small hole that can be used as single-molecule detector. The detection principle is based on monitoring the ionic current reduced by passage of a molecule through the nanopore as a voltage is applied across the nanopore. Here, we introduce biological nanopores and solid-state nanopores. Then, research and current trend about nanopore-based DNA biosensor and protein analysis are reviewed.

  • Immunochemical assay, ELISA for small molecules such as pesticides are rapid, sensitive, cost effective and can easily analyze with large samples. ELISA is one of several powerful biotechnologies immediately applicable to pesticide analysis. This review lists the advantages and disadvantages of the ELISA and elucidate the steps in assay development using examples from this laboratory. The focus is primarily on hapten synthesis strategies, protein conjugation, Immunization, assay format, and assay validation.

  • The polysaccharide fraction from the rhizome of Trichosanthes kirilowii (Cu-curbitaceae) showed marked antitumor and cytotoxic activity with immunopotentiating activity. It was evidenced by the increase in the number of circulating leucocytes and peritoneal exudate cells and the recovery of lowered antibody forming activity in mice. The polysaccharide was mainly composed of glucose, galactose, fructose, manmose and xylose and a small amount of protein.
