It was shown in our previous paper that
the ferrimagnetic structure of Mn Mn4+ (3+) (3) SMMs is dominated by the pi type hybridization between the d(z)2 orbitals at the three high-spin Mn (3+) ions and the t(2g) orbitals at the Mn (4+) ion. This result allows us to predict that the ferrimagnetic structure of Mn4+Mn33+ molecules will be the Fosbretabulin nmr most stable with the Mn4+-(mu(3)-L2-)-Mn3+ angle alpha approximate to 90 degrees, while synthesized Mn4+Mn33+ molecules have alpha approximate to 95 degrees. To design new Mn4+Mn33+ molecules having a much more stable ferrimagnetic state, one following approach is suggested: Controlling the Mn4+-(mu(3)-L2-)-Mn3+ exchange pathways by rational variations in ligands to strengthen the hybridization between Mn ions. By employed N-based ligands to form the Mn4+-(mu(3)-L2-)-Mn3+ exchange
pathways, new distorted cubane Mn4+Mn33+ molecules with alpha approximate to 90 degrees have been designed. These molecules have the Mn4+-Mn3+ exchange coupling of about 2.5 times stronger than that of the synthesized Mn4+Mn33+ molecules. These results should facilitate the rational synthesis of new SMMs. (C) 2011 American Institute of Physics. [doi: 10.1063/ 1.3545812]“
“Objective: The aim of the present study was to investigate whether working memory is impaired in mesial temporal lobe epilepsy with hippocampal sclerosis ZD1839 research buy (MTLE-HS),
a controversial and largely unexplored matter.
Methods: Twenty subjects with left MTLE-HS, 19 with right MTLE-HS, and 21 control right-handed subjects underwent neuropsychological assessment of episodic and semantic memory, executive functions, and specific working memory components.
Results: Left and right epileptogenic foci resulted in impairment of verbal and nonverbal episodic memory (verbal memory learn more deficit greater in left MTLE-HS than in right MTLE-HS). In addition, patients with left MTLE-HS were impaired in teaming paired associates, verbal fluency, and Trail Making. No differences were seen in the tests carried out to evaluate the working memory components (except visuospatial short-term memory in right MTLE-HS).
Conclusion: In this study we did not detect reliable working memory impairment in patients with MTLE-HS with either a left or right focus in most tasks considered as tests of working memory components. (C) 2010 Elsevier Inc. All rights reserved.”
“Background and aims: Diabetes is a risk factor for cardiovascular disease (CVD), yet southern European migrants to Australia with high rates of type 2 diabetes have relatively low CVD mortality. Our aim was to determine whether a Mediterranean style diet could reduce mortality in people with diabetes.
