Increasing evidence shows that pathogenic T cells in type 1 diabetes (T1D) that may have evaded negative selection recognize post-translational modified (PTM) epitopes of self-antigens. We have investigated the profiles of autoantibodies specifically targeting the deamidated epitopes of insulinoma antigen-2 extracellular domain (IA-2ec) to explore their relationship with T1D development. We compared the characteristics of autoantibodies targeting the IA-2ec Q>E epitopes (PTM IA-2ecA) as well as those targeting the IA-2ec unmodified epitopes (IA-2ecA) in participants across different stages of T1D development and in individuals with other types of diabetes and other kinds of autoimmunity.

Despite significant advances in the diagnosis, prognostication, and treatment of thrombotic diseases over the past 3 decades, the adoption of findings stemming from translational biomarker research in clinical practice remains limited. Biomarkers provide an opportunity to enhance our understanding of pathophysiological processes and optimize treatment strategies.

In this case-control study, 68 cases of oral leukoplakia, and 21 of normal oral mucosa (control) were submitted to genotyping of tagSNPs polymorphisms: rs877716 and rs10845877 in NANOG, through real-time polymerase chain reaction (PCR). Pearson's chi-squared and Fisher's exact statistical tests were used, with a significance of 5%.

Purpose: To investigate the association of SOX2 polymorphisms with oral leukoplakia with dysplasia (OLD) and compare it with the immunohistochemical expression of SOX-2.
Methods: The samples comprised 64 patients with oral leukoplakia and 20 with normal oral mucosa who were subjected to SOX2 polymorphism rs77677339 genotyping by real-time polymerase chain reaction and immunohistochemistry for SOX-2 (basal epithelium expression, suprabasal and total; nuclear area and intensity). Statistical tests included the Chi-square and Fisher's exact tests.
A Cu-TiO nanomaterial with unique antibacterial and photocatalytic properties is introduced in this study. Cu-TiO nanocomposites were obtained using an adapted direct current magnetron sputtering apparatus, where TiO anatase nanoparticles (NPs) were used as the substrates and copper as the sputtering target. The obtained powder was characterized by physical and chemical methods.
