Broken Symmetry and Elastic Frustration in Isostructural Spin Crossover Crystals.

Symmetry-breaking spin-state transitions in two of three isostructural salts of MnIII spin-crossover cations, [MnIII(3-OMe-5-NO2-sal2323)]+, with heavy anions are reported. The ReO4-  salt undergoes two-step spin crossover which is coupled with a re-entrant symmetry-breaking structural phase transition between a high temperature phase (S = 2, C2/c), an intermediate ordered phase (S = 1/S = 2, P21/c), and a low temperature phase (S = 1, C2/c). The AsF6-  complex undergoes an abrupt transition between a high temperature phase (S = 2, C2/c) and a low temperature ordered phase (S = 1/S = 2, P-1).

Potential Synergy of Fluoxetine and Antibacterial Agents Against Skin and Soft Tissue Pathogens and Drug-Resistant Organisms.

The feasibility of repurposing selective serotonin reuptake inhibitors as adjunctive antibacterial agents is an area of current investigation. We sought to evaluate if fluoxetine will achieve synergistic killing with relevant antibacterial drugs against skin and soft tissue pathogens and multidrug-resistant pathogens. : The MIC of fluoxetine was determined using broth microdilution for a diverse isolate collection of 21 organisms.

Coastal redox shifts over the past 167 years and preservation of total organic carbon and total nitrogen.

This study reconstructs the environmental history of Xincun Lagoon over the past 167 years using sediment core XCW, employing Cu/Zn as a proxy for redox changes. Time-series analysis of Cu/Zn ratios reveals a significant decline (linear regression slope = -0.00082, p < 0.

Case report: Clinical and immunohistochemical manifestations of suspected Sjogren's disease in a dog.

Sjogren's disease, well-described in people, is rarely identified in veterinary species. In people, Sjogren's disease is one of the most common systemic autoimmune disorders with an incidence of 0.5% in the female population.
