We describe the synthesis of a cyapho(dicyano)methanide salt, [K(18-crown-6)][C(CN)2(CP)], from reaction [Na(18-crown-6)][PH2] (18-crown-6=1,4,7,10,13,16-hexaoxacyclooctadecane) with 1,1-diethoxy-2,2-dicyanoethylene (EtO)2C=C(CN)2. The proceeds through Michael addition-elimination pathway to afford [Na(18-crown-6)][HP{C(OEt)=C(CN)2}]. Addition strong, non-nucleophilic base (KHMDS) this intermed...

Toxic shock syndrome toxin-1 (TSST-1) producing strains of Staphylococcus aureus isolated from 18 patients with toxic shock syndrome (TSS) and from 56 patients with other diagnoses were compared for capacity to interact with various serum and connective tissue proteins. TSS associated isolates showed significantly stronger binding of Type-I collagen (Cn-I) and Cn-II than non-TSS strains, in a p...

We performed this study to evaluate the effect of cavernous nerve (CN) traction on erectile function in rats. Thirty-two 8- week-old Sprague-Dawley rats were divided into four groups: control, 1-minute CN traction, 2-minute CN traction, and 2-minute CN crush. CN traction was performed using a glass hook with a tensile force of 0.2 Newton. One month later, the mean arterial pressure (MAP) and in...

Performance, digestibility of nutrients, microbial nitrogen flow (MNF) and nitrogen efficiency (NE) inearly lactating Holstein cows were investigated by diet supplementation with sodium caseinate (CN).Multiparous lactating Holstein cows (n = 15) with an average body weight of 638 kg and 21 days in milkwere assigned to a completely randomized design (five cows per treatment) and fed a basal diet...

Recently, polymeric carbon nitride (g-C3N4) as a proficient photo-catalyst has been effectively employed in photocatalysis for energy conversion, storage, and pollutants degradation due to its low cost, robustness, environmentally friendly nature. The critical review summarized the recent development, fundamentals, nanostructures design, advantages, challenges of g-C3N4 (CN), potential future p...
