Influence of the disposition of the anisotropy axes into the magnetic properties of Mn-III dinuclear compounds with benzoato derivative bridges

The two new Mn-III dinudear compounds [{Mn-(H2O)(phen)}(2)(mu-4-CH3C6H4COO)(2)(mu-O)](ClO4)(2)center dot 3CH(3)CN center dot H2O (1.3CH(3)CN center dot H2O) and [{Mn(H2O)(phen)}(mu-O)](mu-2-BrC6H4COO)(2){Mn(NO3)(phen)}]NO3 (2) have been synthesized. Their structural data reveal significant differences in the shape of the coordination octahedron around the Mn-III ions in both compounds. The different distortions from ideal geometry incite a very different magnetic behavior, affecting both the zero-field splitting parameters of the Mn-III ions (D-Mn and E-Mn) and the magnetic interaction between them. Compound 1, with elongation in the monodentate ligand direction, shows antiferromagnetic coupling (ground state S = 0) and local D-Mn 0. Theoretical CASSCF and DFT calculations corroborate the different magnetic anisotropy and exchange coupling found in both compounds. Moreover, with the help of theoretical calculations, some interesting magneto-structural correlations have been found between the degree of distortion of the coordination octahedra and the magnetic coupling; it becomes more antiferromagnetic when the elongation parameter, Delta, in absolute value is increased

Chemical probes for the recognition of cannabinoid receptors in native systems.

Receptors made visible: The described biotin-tagged small-molecule probes with excellent affinities for the CB(1) and CB(2) cannabinoid receptors (CB(1)R and CB(2)R) enable direct visualization of these receptors in native cellular systems, including neurons, microglia, and immune cells. This method could overcome some of the limitations of current methodologies and may help to dissect the complexity of the endogenous cannabinoid system.Journal ArticleResearch Support, Non-U.S. Gov'tFLWINinfo:eu-repo/semantics/publishe

Primary health care utilization by immigrants as compared to the native population: a multilevel analysis of a large clinical database in Catalonia

Background: Immigration is a relevant public health issue and there is a great deal of controversy surrounding its impact on health services utilization. Objective: To determine diff erences between immigrants and non-immigrants in the utilization of primary health care services in Catalonia, Spain. Methods: Population based, cross-sectional, multicentre study. We used the information from 16 primary health care centres in an area near Barcelona, Spain. We conducted a multilevel analysis for the year 2008 to compare primary health care services utilization between all immigrants aged 15 or more and a sample of non-immigrants, paired by age and sex. Results: Overall, immigrants living in Spain used health services more than non-immigrants (Incidence Risk Ratio (IRR) 1.16 (95% Confi dence Interval (CI): 1.15 – 1.16) and (IRR 1, 26, 95% CI: 1.25 – 1.28) for consultations with GPs and referrals to specialized care, respectively. People coming from the Maghreb and the rest of Africa requested the most consultations involving a GP and nurses (IRR 1.34, 95% CI: 1.33 – 1.36 and IRR 1.06, 95% CI: 1.03 – 1.44, respectively). They were more frequently referred to specialized care (IRR 1.44, 95% CI: 1.41 – 1.46) when compared to Spaniards. Immigrants from Asia had the lowest numbers of consultations with a GP and referrals (IRR 0.76, 95% CI: 0.66 – 0.88 and IRR 0.76, 95% CI: 0.61 – 0.95, respectively. Conclusion: On average , immigrants living in Catalonia used the health services more than non-immigrants. Immigrants from the Maghreb and other African countries showed the highest and those from Asia the lowest, number of consultations and referrals to specialized care
