Mouse Anti-Bovine Myosin Hybridoma [CG-G4]

Silicate-sulfide liquid immiscibility in mantle-derived magmas has important control on the budget of siderophile and chalcophile metals, and is considered to be instrumental in the origin orthomagmatic sulfide deposits. Data on primitive sulfide melts in natural samples, even those representing most voluminous magmatism in oceanic rifts, are very scarce due to the small size and poor preservation of incipient sulfide melt globules. Here we present the first detailed report of the crystallized sulfides melts in the oceanic picrites of the (presumably) Cretaceous age Kamchatsky Mys ophiolite complex in Eastern Kamchatka (Far East Russia). Sulfide melts are present in three forms; (1) as inclusions in olivine (87.1-89.6 mol% Fo), (2) interstitial to the groundmass minerals (clinopyroxene, plagioclase, and Ti-magnetite) of studied picrites, and (3) as daughter phases in silicate melt inclusions hosted by olivine and Cr-spinel phenocrysts. The sulfide melt inclusions in olivine and the groundmass of studied rocks are composed of several sulfide phases that correspond to the monosulfide (Fe-Ni; Mss) and intermediate (Fe-Cu-Ni; Iss) solid solutions. Several <0.5 mu m Pd-Sn, Pt-Ag, and Au-Ag phases are recorded within the matrix sulfides, commonly along phase boundaries and fractures. Major elements (S, Fe, Cu, Ni, Co), platinum group elements (PGE), and gold analyzed in the homogenized olivine-hosted sulfide melt inclusions, and phases identified in the matrix sulfides record the range of magmatic sulfide compositions. The most primitive sulfide liquids are notably enriched in Ni and Cu [(Ni+Cu)/Fe, at% > 0.5], continuously evolve with crystallization of (e.g., increasing Cu/Ni and Au/PGE) and demonstrate metal fractionation between Mss and Iss. Although the compositional systematics found in this study are consistent with those previously recorded, the compositions of individual sulfide phases are strongly affected by the noble metal (PGE, Au) "nuggets" that exsolve at subsolidus temperatures and form during serpentinization of the rocks. We conclude that the budget of noble metals in the studied picrites is controlled by sulfides, but the abundances of Pt and Au are influenced by mobility in post-magmatic alteration. Our data can be also used for modeling sulfide saturation at crustal pressures and understanding behavior of the noble metals in primitive oceanic magmas.

Objective: Esophageal cancer is the eighth most common cancer in the world. About 80% of cases occur in less developed regions. The study purposed to investigate the epidemiology of esophageal cancer incidence and mortality in 185 countries and its relation with HDI in 2018. Materials and Methods: A descriptive-analytical study was developed based on cancer incidence and mortality data extraction from the World Bank for Cancer in 2018. The incidence and mortality rates and esophagus cancer distribution maps were drawn for World countries. To analyze data, correlation and regression tests were used to evaluate the relationship between the incidence and mortality with HDI. The statistical analysis was carried out by Stata-14, and the significance level was estimated at 0.05 level. Results: The highest and the lowest esophageal cancer incidences were in the Asian continent (N=444597; 77.7%) and the Oceania continent (N=2315; 0.4%). The most esophageal cancer incidence and mortality was in high HDI regions. A negative and significant correlation was observed between incidence (R = -0.143, p <0.05) and mortality (R = 0.234, p <0.05) of esophagus cancer and HDI. Furthermore, there was a negative and significant correlation between incidence rate and LEB (r = -0.16, p <0.05). Also, the results showed a negative and significant correlation between mortality rate and GNI (r = 0.1, p <0.05), MYS (r = -0.17, p <0.05), LEB (r = -0.23, p <0.05) and EYS (r = -0.15, p <0.05). Conclusions: There is a negative correlation between esophageal cancer incidence and mortality as well as the HDI index, improving the HDI can be effective in reducing of the cancer incidence and mortality.
