Uukuniemi virus, a member of the Bunyaviridae family, was grown in BHK-21 cells in the presence of [(3)H]mannose. The purified virions were disrupted with sodium dodecyl sulfate and digested with pronase. The [(3)H]mannose-labeled glycopeptides of the mixture of the two envelope glycoproteins G1 and G2 were characterized by degrading the glycans with specific exo-and endoglycosidases, by chemic...

An unstable [t1/2 at 37 degrees = 32 +/- 2 (SD) sec] intermediate, thromboxane A2, was detected in the conversion of prostaglandin G2 into 8-(1-hydroxy-3-oxopropyl)-9,12L-dihydroxy-5,10-heptadecadienoic acid (thromboxane B2) in platelets. The intermediate was trapped by addition of methanol, ethanol, or sodium azide to suspensions of washed human platelets incubated for 30 sec with arachidonic ...

I read with interest the article "Accuracy of ASGE criteria for the prediction of choledocholithiasis" by Nárvaez et al. Patients with suspicion of choledocholithiasis (CL) were categorized according to the American Society for Gastrointestinal Endoscopy (ASGE) recommendations. Those patients classified into high or intermediate-probability for CL underwent an endoscopic retrograde cholangiopan...

The purification and characterization of acetylcholinesterase from heads of the fruit fly Drosophila are described. Sequential extraction procedures indicated that approximately 40% of the activity was soluble and 60% membrane-bound and that virtually none (less than 4%) corresponded to collagen-tailed forms. The membrane-bound enzyme was extracted with Triton X-100 and purified over 4000-fold ...

A slow hydrolyzing imidazole-based Ru(II)-arene complex [(L)Ru(II)(η(6)-p-cym)(Cl)](PF6) (1) with excellent stability in the extracellular chloride concentration shows better activity under hypoxia and strong resistance to glutathione (GSH) in vitro under hypoxic conditions. 1 arrests the cell cycle in sub G1 and G2/M phases and leads to apoptosis.

A nitridoosmium(VI) complex [Os(VI)(N)(sap)(OH(2))Cl] (H(2)sap = N-salicylidene-2-aminophenol) displays prominent in vitro and in vivo anti-cancer properties, induces S- and G2/M-phase arrest and forms a stable adduct with dianionic 5'-guanosine monophosphate.

For a graph G we denote by dG(u, v) the distance between vertices u and v in G, by dG(u) the degree of vertex u. The Hosoya polynomial of G is H(G) = ∑ {u,v}⊆V (G) x dG (u,v). For any positive numbers m and n, the partial Hosoya polynomials of G are Hm(G) = ∑ {u, v} ⊆ V (G) dG (u) = dG (v) = m xdG (u,v), Hmn(G) = ∑ {u, v} ⊆ V (G) dG (u) = m, dG (v) = n xdG (u,v). It has been shown that H(G1) − ...
