Gender differences in the prevalence and management of metabolic syndrome and its components in patients with peripheral artery disease

We compared the prevalence and management of metabolic syndrome (MetS) and its components in men and women with peripheral artery disease (PAD). A total of 70 men and 70 women with PAD were evaluated for presence of MetS. There was no significant gender difference in presence of MetS (P = .399) and the number of MetS components (P = .411). Among PAD patients with each MetS component, there was no significant gender difference in the use (P = .617) and number (P = .716) of blood pressure medications, the use (P = .593) and number (P = .591) of lipid-lowering medications, and the number (P = .155) of diabetic medications. Significantly more women were treated with diabetic medications compared with men (85 vs 57%, P = .026). The prevalence and management of MetS and its components was similar between men and women with PAD, except that more women were treated for diabetes. Patients with PAD having MetS did not receive optimal medical management.     

Promiscuous peptide of 16 kDa antigen linked to Pam2Cys protects against Mycobacterium tuberculosis by evoking enduring memory T-cell response

One of the main reasons considered for BCG failure in tuberculosis-endemic areas is impediment by environmental mycobacteria in its processing and generation of memory T-cell response. To overcome this problem, we developed a unique lipopeptide (L91) by linking the promiscuous peptide (sequence 91-110) of 16 kDa antigen of Mycobacterium tuberculosis to Pam2Cys. L91 does not require extensive antigen processing and generates enduring Th1 memory response. This is evidenced by the fact that L91 significantly improved the activation, proliferation, and generation of protective T cells. Furthermore, L91 surmounts the barrier of major histocompatibility complex polymorphism and induces better protection than BCG. This peptide has self-adjuvanting properties and activates dendritic cells. Importantly, L91 activates T cells isolated from purified protein derivative-positive healthy volunteers that responded weakly to free peptide (F91). In essence, L91 can be a potent future vaccine candidate against tuberculosis.     

Using fuzzy association rule mining in cancer classification

The classification of the cancer tumors based on gene expression profiles has been extensively studied in numbers of studies. A wide variety of cancer datasets have been implemented by the various methods of gene selection and classification to identify the behavior of the genes in tumors and find the relationships between them and outcome of diseases. Interpretability of the model, which is developed by fuzzy rules and linguistic variables in this study, has been rarely considered. In addition, creating a fuzzy classifier with high performance in classification that uses a subset of significant genes which have been selected by different types of gene selection methods is another goal of this study. A new algorithm has been developed to identify the fuzzy rules and significant genes based on fuzzy association rule mining. At first, different subset of genes which have been selected by different methods, were used to generate primary fuzzy classifiers separately and then proposed algorithm was implemented to mix the genes which have been associated in the primary classifiers and generate a new classifier. The results show that fuzzy classifier can classify the tumors with high performance while presenting the relationships between the genes by linguistic variables.
