Raman spectroscopy of organic molecular materials in the low-wavenumber region gives access to lattice vibrational modes and wealth information on solid state properties that these can provide. In field electronics a useful application concerns discrimination crystalline forms i. e. polymorphism semiconductor. The capability characterizing identifying polymorphs compound is fact prerequisite fo...

A fundamental challenge in population genetics and molecular evolution is to understand the forces shaping the patterns of genetic diversity within and among species. Among them, mating systems are thought to have important influences on molecular diversity and genome evolution. Selfing is expected to reduce effective population size, Ne, and effective recombination rates, directly leading to r...

The results of this study demonstrate the existence of molecular heterogeneity (polymorphism) within DR beta-chains isolated from a single serologically defined DR phenotype, DR4. The data are consistent with the possibility that this polymorphism is related to the Dw/LD phenotype as defined with the cellular reagents, homozygous typing cells.

BACKGROUND The apolipoprotein E gene (APOE) coding polymorphism modifies the risks of Alzheimer's disease, type 2 diabetes, and coronary heart disease. Aside from the coding variants, single nucleotide polymorphism (SNP) of the APOE promoter has also been shown to modify the risk of Alzheimer's disease. METHODOLOGY/PRINCIPAL FINDINGS In this study we investigate the genotype-function relation...

skin cancer is one of the most important type of cancers in the world. in this way, molecular investigation in order to detect some novel mechanisms and polymorphisms involved in cancer development can be impressive and vital. in this way, the aim of this study was the histopathological investigation of skin cancer and its relationship with polymorphism of cdkn2a gene. this case-control study w...

background: recurrent pregnancy loss (rpl) is defined as two or more miscarriages before the 20 th week of gestation and its etiology is unknown in 50% of the cases. interleukin 6 is an immune mediator, plays a regulatory role in embryo implantation and placental development. objective: the purpose was to assess the association between il-6 -634c/g polymorphism and, susceptibility to idiopathic...

Background: This study was done in order to enhance our understanding about molecular and epidemiological features of breast cancer among the Azeri population with special emphasis on the detection of TP53 mutations. We also analyzed the role of the P53codon72 polymorphism (rs1042522) and its role in susceptibility to breast cancer. Methods: ...
