This work evaluates the quality of exchange coupling constant and spin crossover gap calculations using density functional theory corrected by the Approximate Projection model. Results show that improvements using the Approximate Projection model range from modest to significant. This study demonstrates that, at least for the class of systems examined here, spin-projection generally improves the quality of density functional theory calculations of J-coupling constants and spin crossover gaps. Furthermore, it is shown that spin-projection can be important for both geometry optimization and energy evaluations. The Approximate Project model provides an affordable and practical approach for effectively correcting spin-contamination errors in molecular exchange coupling constant and spin crossover gap calculations.

Negative Attitudes

Abstract: The patients’ attitudes towards kidney transplantation are significantly affected by the acceptance of the treatment to have a better quality of life. Exploration of the cognitive-emotional relation in patients with chronic renal failure. Our study included 285 kidney patients. We investigated three groups of patients: predialysis, dialysis and transplantation patients. In the framework of a pre-examination we have created an attitudinal questionnaire (85 items) that can be used to describe the cognitive and emotional attitude of kidney patients towards their illness and to measure scales. Negative attitudes towards transplantation were reported in dialysis and predialysis patients. In contrast, patients who had already undergone surgery were particularly positive about kidney transplantation. Many patients refuse transplantation which correlates with attitudes towards illness and healing. Our results showed that the exploration of the patients’ cognitive emotional relation along with the medical diagnosis would have a better adherence towards the kidney substitutional treatment which ensures a better quality of life.

Stereotactic Guidance

Cryosurgical method is used in treatment of patients with glial tumors which localized in depth and functionally meaningful brain areas. These patients are generally considered as inoperable and receive conservative treatment. Their prognosis has become worse as compared to the patients whose brain tumor is available for surgical removal. The authors used a multiway stereotactic destruction of tumors by cryosurgical cannula, which is inserted in bone cutter opening using manipulator. MR-imaging and PET/CT of brain were applied for stereotactic guidance. The majority of patients who underwent this operation didn’t noticed any loss of quality of life. The rates of survival were higher than corresponding indicators for patients who were treated only by chemo- or radiation therapy and the rates were equal to the patients underwent the radical operations. Thus, the multiway stereotactic cryodestruction is a new, safe and effective method of surgical treatment for the patients with tumor localization in such areas, that their location blocked an application of traditional surgical removal by open method.
