Partial cDNA clones generated by RT-PCR were used as probes to clone the cDNAs encoding the human alpha 4 and beta 2 neuronal nicotinic acetylcholine receptor (nAChR) subunits. The 2.1-kb alpha 4 cDNA shows 84 and 76% identity to the rat and chicken cDNA sequences, respectively. The deduced amino-acid sequence shares 89 and 84% similarity, respectively, with the corresponding rat and chicken proteins, with most of the divergence occurring in the cytoplasmic domain. The 1721-nucleotide beta 2 sequence was identical to the human beta 2 sequence previously reported. Transfection of the alpha 4 and beta 2 clones into HEK293 cells resulted in the formation of binding sites that display high affinity towards [3H] cytisine, a characteristic of the alpha 4 beta 2 subtype produced in vivo.

The study of chalcone-1,2,3-triazole hybrids for anticancer activity is quite a recent area of focus, primarily because of the increasing demand for developing new drugs to treat cancer. The chalcones and 1,2,3-triazole rings in hybrid compounds has recently emerged as a promising strategy for developing novel anticancer agents. The 1,2,3-triazole ring, known for its stability and hydrogen bonding capabilities, enhances the target binding affinity of these hybrids.

Carbonic anhydrases (CAs) are ubiquitous enzymes that catalyze reversibly both the hydration and dehydration reactions of CO and HCO-, respectively. Higher plants contain many different isoforms of CAs that can be classified into α-, β- and γ-type subfamilies. β-type CAs play a key role in the CO-concentrating mechanism, thereby contributing to efficient photosynthesis in the C plants in addition to many other biochemical reactions in plant metabolism.

Mushrooms and fenugreek are widely used to reduce hyperglycemia, and fenugreek is also used as a culinary ingredient to enhance flavor and aroma. This study is aimed at investigating the underlying mechanisms of the hypoglycemic effects of mushrooms and fenugreek in a Type 2 diabetic rat model. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) functions to reduce hyperglycemia through insulin-independent pathways and protects beta-cells.

The McNamara (MCN) and Wedenberg (WED) RBE weighted dose (D), dose and dose-weighted average LET (LET) were calculated in twenty brain cancer patients. A linear approximation was made for each RBE model to give best agreement to clinically relevant dosimetric parameters. Additional evaluations were done on twenty head and neck and twenty breast cancer patients.
