Association of CCR5Δ32 Deletion and Human Cytomegalovirus Infection With Colorectal Cancer in Tunisia.

Unlabelled: Human cytomegalovirus (HCMV) and genetic polymorphisms of the chemokine receptor 5 have been suggested as factors associated with the progression of colorectal cancer (CRC). The aim of the study was to evaluate the associations of both CCR5Δ32 genetic deletion and/or HCMV virus infection with CRC in Tunisia.

Materials And Methods: The association between HCMV and CRC was validated by Nested PCR technology performed for HCMV and HCMV-specific serum IgG and IgM antibodies were investigated by enzyme-linked immunosorbent assay.

Rapid high-resolution melting method to identify human leukocyte antigen-G (HLA-G) 3' untranslated region polymorphism +3142C/G (rs1063320).

Background: HLA-G is a non-classical class I gene of the human Major Histocompatibility encoding molecules with immune-modulatory properties. Expression of HLA-G is being largely studied in pathological conditions, such as tumors, viral infections, inflammation, and autoimmune diseases, grafted tissues, among others. HLA-G +3142C/G (rs1063320: dbSNP database) polymorphism is located in 3' UTR of HAL-G and plays a key role in determining the magnitude of gene and protein expression.

Contributions of autism evaluation unit in the clinical diagnosis of autism spectrum disorders.

Background: Based on the recognized principles of assessment of autistic disorders, the child and adolescent psychiatry department in Razi Hospital developed, in coordination with the department of neurology of Razi Hospital and the department of genetics of Charles Nicolle's Hospital an assessment unit for autism spectrum disorders.

Objective: To describe the clinical characteristics in terms of severity and comorbidities of children assessed for autism spectrum disorders.

Methods: We compiled data about clinical examination of autistic symptoms using the Autism Diagnostic Interview Revised (ADI-R) and the Childhood autism Rating Scale (CARS).
