Molecular docking based screening of triterpenoids as potential G-quadruplex stabilizing ligands with anti-cancer activity.

Triterpenoids isolated from Ganoderma lucidum (GLTs) exhibit a broad spectrum of anti-cancer properties, including anti-proliferative, anti-metastatic and anti-angiogenic activities. Current research studies revealed the role by GLTs in inducing apoptosis and suppression of telomerase activity of cancer cells with much lower toxicity to healthy cells. Compounds selectively binding and stabilizing G-quadruplex structures could inhibit the telomerase or downregulate the oncogenes and may act as anti-cancer agents.

Association between butyrylcholinesterase K variant and mild cognitive impairment in the Thai community-dwelling patients.

Objective: To study the association of the butyrylcholinesterase K variant (BChE-K) and the plasma BChE activity with mild cognitive impairment (MCI) in Thai community-dwelling patients.

Methods: One hundred patients diagnosed with MCI and 100 control subjects were recruited from the community-dwelling setting in Bangkok, Thailand. The genotype and allele distributions of the BChE-K were determined by polymerase chain reaction and subsequent DNA sequencing.

The "intermediate syndrome" as critical sequelae of organophosphate poisoning: the first report of two cases in Thailand.

The authors report 2 cases of organophosphate poisoning which developed intermediate syndrome. The first case was a man who took an organophosphate insecticide, monocrotophos, and developed severe organophosphate poisoning. Respiratory support was needed.

Genetic polymorphisms and haplotypes of DNA repair genes in childhood acute lymphoblastic leukemia.

Background: Polymorphisms of DNA repair genes can alter protein structure and may impair DNA repair capacity. Defects in repairing damaged DNA lead to genetic instability and carcinogenesis. This study was performed to evaluate the effect of the polymorphisms of DNA repair genes on risk of childhood acute lymphoblastic leukemia (ALL).
