[en] To determine the frequency of diabetes mellitus in non ST segment elevation myocardial infarction. Study Design: Cross-sectional. Place and Duration of Study: The study was carried out at the Armed Forces Institute of Cardiology (AFIC) Rawalpindi, from Apr 2010 to Oct 2010. Material and Methods: In this study three hundred fifty two patients with non ST elevation myocardial infarction (NSTEMI) who fulfilled the inclusion criteria were studied while they were admitted to the hospital. They were divided into diabetic and non diabetic groups. Frequency of age, gender, rising levels of cardiac biochemical markers, plasma glucose and HbA1c were seen in both diabetic and non diabetic patients. Results were obtained by using chi-square method and independent t-test. Results: Out of 352 patients of NSTEMI 193 were diabetics. The study population was categorized in three groups according to age as; 30-45, 46-60, and 61-75 years respectively. It was found that 46-60 years group was most frequently affected with frequency of 46.1%, p<0.001 with male predominance as 67.9% and females as 32.1%. Cardiac biochemical markers were raised with mean for CK 528.51 U/L SD +- 275.82 and CK MB 79.39 U/L SD +- 32.5, p<0.001 respectively. Raised fasting plasma glucose was found in 189 patients mean 8.74 mmol/L SD +- 1.52, p<0.001 and elevated HbA1c seen in 187 patients mean 7.94% SD +- 0.83, p<0.001. Conclusion: Despite modern therapies for unstable angina (UA)/NSTEMI diabetes is an independent cardiovascular risk factor, therefore we need aggressive strategies to manage the high risk group of patients.

[en] A systematic theoretical study was performed for dipolar triarylamine-based Dπ-A dyes. These dyes are composed of good required features to be active for enhancing the efficiency of solar cell such as arylamine donor moieties, and an acceptor part with cyanoacetic acid, while the conjugation process is adopted by the fluorene or biphenyl linkers. The required properties both electronic and opticals were computed with DFT/TDDFT levels and 6-31G (d, p) basis set, then show the response of the efficiency. The obtained results have predicted the excitation energies, HOMO-LUMO energy levels which indicate an improvement in the two principle processes; electron injection and the regeneration of dyes. Also, the important factors in close connection with the short-circuit current density (J_sc), such as light-harvesting efficiency (LHE), the open-circuit photovoltage (V_oc), total reorganization energy (λ_total) and injection driving force (ΔG_inject) have been explained. As a result, the calculated data verify that the D dye can represent a potential sensitizer for solar cells, this can be rationalized by its reasonable photovoltaic parameters with other electronic and optical properties.
