In this paper, we propose a selective mutation method for improving the performances of genetic algorithms. In selective mutation, individuals are first ranked and then additionally mutated one bit in a part of their strings which is selected corresponding to their ranks. This selective mutation helps genetic algorithms to fast approach the global optimum and to quickly escape local optima. Thi...
fryns-aftimos syndrome is a rare autosomal dominant disorder characterized by craniofacial signs, anterior neuronal migration disorder (pachygyria, lissencephaly), skeletal deformities and mental retardation. we describe a five-year-old boy with abnormal facial features (hypertelorism, ptosis, high arched palate), skeletal problems (short stature, short fingers, flat feet) and mild intellectual...
Mutation in homologous recombination repair (HRR) pathway is well established ovarian cancers. Multiple trials have shown variable efficacy prostate Mutations other than BRCA1/BRCA2 been recently reported We describe a unique case of an elderly male with metastatic castration-resistant cancer. He responded to hormonal therapy for 6 months but later progressed. Chemotherapy docetaxel produced se...
Background: Factor V Leiden, Prothrombin gene (G20210A) and MTHFR (C677T) polymorphism are the main biomarkers for evaluation of tendency for venous thromboembolism. We aimed to investigate the frequency of mutations in factor V Leiden, Prothrombin G20210A and MTHFR C677T and identify the genetic status for these mutations in patients with venous thrombosis. Methods: This study was carried out...
