Using molecular simulations, we analyze the microscopic processes driving the Nuclear Magnetic Resonance (NMR) relaxation of quadrupolar cations in water. The fluctuations of the Electric Field Gradient (EFG) experienced by alkaline and magnesium cations, which determine the NMR relaxation time, are mainly due to the dynamics of water molecules in their solvation shell. The dynamics of the ion ...

Among the invasive insect species, Halyomorpha halys (Stål) (Heteroptera: Pentatomidae), has been causing significant damages in many parts of world, particularly vegetables, field crops and tree fruits. In scientific studies conducted Türkiye world so far, egg parasitoids H. have found, but adult not detected. Two specimens Cylindromyia bicolor were reared from an collected northern (Borçka, A...

A basic sPLA 2 (D49) from the venom of snake Agkistrodon piscivorus leucostoma (AplTX-II) was isolated, purified and characterized. We determined enzymatic pharmacological profiles this toxin. AplTX-II isolated with a high level purity through reverse phase chromatography molecular exclusion. The enzyme showed pI 9.48 weight 14,003 Da. activity depended on Ca 2+ pH temperature. comparison prima...

Applaggin (Agkistrodon piscivorus piscivorus platelet-aggregation inhibitor) is a potent inhibitor of blood platelet aggregation derived from the venom of the North American water moccasin. The protein consists of 71 amino acids, is rich in cysteines, contains the sequence-recognition site of adhesion proteins at positions 50-52 (Arg-Gly-Asp) and shares high sequence homology with other snake-v...

Acutolysin A, a protein isolated from the venom of Chinese Five-pace snake (Agkistrodon acutus) has shown marked hemorrhagic and proteolytic activities. In the present study, the effects of metal ions and an inhibitor EDTA on the fluorescence and function of autolysin A have been studied, by following fluorescence and activity measurements. Acutolysin A contains a Ca(2+)-binding site, which pro...

Studies of population genetics increasingly use next-generation DNA sequencing to identify microsatellite loci in nonmodel organisms. There are, however, relatively few studies that validate the feasibility of transitioning from marker development to experimental application across populations and species. North American coralsnakes of the Micrurus fulvius species complex occur in the United St...
