The calculated vertical excitation energies for lowest excited states are in reasonable accordance with those determined by the calculations of the whole systems with traditional methods, showing that our new fragment-based method can give good estimates for low-lying energy spectra of both weak and moderate interaction systems with economic computational costs.

“AimA possible association between the transforming growth factor-1 (TGF-1) T869C gene polymorphism and the risk of developing diabetic nephropathy (DN) remains unclear. This investigation was performed to assess if an association between the
TGF-1 T869C gene polymorphism and DN risk exists by using meta-analysis to combine comparable studies, thereby increasing sample size and statistical significance, and
to identify patterns in various studies.\n\nMethodsThe association reports were identified from PubMed, Cochrane Library, and CBM-disc (China Biological Medicine Database) on 1 May 2013, and eligible studies were recruited and synthesized.\n\nResultsFifty reports were recruited into this meta-analysis for the association of the TGF-1 T869C gene polymorphism with DN risk. The TT genotype in the overall population was shown to be associated with DN risk (odds ratio (OR)=0.74, 95% confidence interval (CI): 0.56-0.98, P=0.04). In the sub-group analysis, CC genotype was associated with DN risk in Asians, Caucasians, and see more Africans. However, the sample size for Caucasians and Africans was relatively small. Furthermore, T allele was distinctly associated with the risk of developing DN in Rabusertib the Asian population (OR=0.76, 95% CI: 0.62-0.92, P=0.005).\n\nConclusionsThe TT genotype of TGF-1 T869C in the overall population was associated with DN risk, whereas the CC genotype and T allele were distinctly associated with DN risk in the Asian population.
Nonetheless, additional studies are required to firmly establish a correlation between the aforementioned polymorphism and DN risk.”
“Background: Evidence indicates that the rising trend in overweight and obesity may be stronger for people from more socioeconomically advantaged backgrounds.\n\nPurpose: This study used longitudinal, multilevel data to describe trajectories of BMI for people living in more- versus less-deprived neighborhoods.\n\nMethods: Data from 2501 women and 5650 men in the Whitehall II study who were followed for up to 13 years from 1991 to 2004 were analyzed in 2009. BMI was measured on up to three occasions by a trained nurse. The Townsend index of multiple deprivation at census-ward level from the 1991 U.K. census captured neighborhood deprivation. Growth curves summarized change in BMI for men and women according to level of neighborhood deprivation, adjusted for age, individual socioeconomic position (captured by civil service employment grade), smoking status, alcohol intake, and physical activity level.
