Abstract:
A ground-glass opacity (GGO) lesion was discovered in a 64-year-old female 1 year ago. One month before administration, a follow-up CT showed the lesion in the apical segment of left upper lobe had increased from 8 to 11 mm in diameter. The lesion was diagnosed to be cT1aN0M0 non-small cell lung cancer (NSCLC) and a 3-port video-assisted thoracic surgery (VATS) anatomic segmentectomy was performed. Intraoperative frozen sections revealed a microinvasive adenocarcinoma. Systematic lymph node dissection was then carried out. The final pathological result showed a pT1aN0M0 (Ia) adenocarcinoma.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
