[Association between Metabolic Syndrome and Risk of Hearing Loss: a Systematic Review and Meta-analysis].

Introduction: Various studies have linked lifestyle and metabolic diseases to hearing loss. Research on metabolic syndrome has reported a higher prevalence of hearing loss in individuals with it than those without it.

Objectives: To conduct a systematic review and meta-analysis summarizing the risk of hearing loss in people diagnosed with metabolic syndrome or diseases versus those without metabolic syndrome.

Phosphorylation of Phylogenetically Conserved Amino Acid Residues Confines HBx within Different Cell Compartments of Human Hepatocarcinoma Cells.

Hepatitis B virus (HBV) is a circular, and partially double-stranded DNA virus. Upon infection, the viral genome is translocated into the cell nucleus, generating the covalently closed circular DNA (cccDNA) intermediate, and forming a mini chromosome. HBV HBx is a small protein displaying multiple roles in HBV-infected cells, and in different subcellular locations.

Vehicle routing problem for reverse logistics of End-of-Life Vehicles (ELVs).

Reverse logistics management of End-of-Life Vehicles (ELVs) is increasingly focusing on practical solutions for getting additional value from products at the end of their life. As automotive is one of the fastest-growing sectors, the number of ELVs to be collected and recycled has been steadily increasing due to more stringent regulations. On the other hand, the operational cost (transportation) of collecting ELVs might exceed half of the purchased price.

[Hepatitis C virus in a group of hematological and oncohematological patients].

Background: Little information is available in Chile about hepatitis C virus (HCV) in hematological and oncohematological patients.

Aim: To evaluate the prevalence of hepatitis C virus markers in a group of hematological and oncohematological pediatric patients seen at Valdivia Regional Hospital.

Patients And Methods: Antibodies against virus C, determined by ELISA and viral RNA, determined using RT-polymerase chain reaction, were measured in 54 blood samples from children with hematological diseases (34 with Acute Lymphoblastic Leukaemia, 4 with Hodgkin Diseases, 4 with Haemolytic Anemia, 5 with Sarcomas, 2 with Non-Hodgkin Lymphoma, 2 with Thrombocytopenic Purpura, 1 with an Ependimoma, one with a Wilms Tumor and 1 with a Von Willebrand Disease).
