The hemoflagellate parasite Trypanosoma rangeli is transmitted by triatomine kissing bugs and may co-infect humans together with its Chagas disease-causing congener T. cruzi . Using real-time quantitative polymerase chain reaction (RT-qPCR) and antimicrobial assays, we studied ( i ) the temporal and spatial distribution of T. rangeli in common bed bugs, Cimex lectularius , following oral ingestion and hemocoelic injection of T. rangeli, and ( ii ) the immune responses of bed bugs induced by T. rangeli infections. Irrespective of infection mode, no live T. rangeli were present in the bed bugs’

This study investigated the immunohistochemical staining characteristics of glutathione-S-transferase alpha, pi, mu, theta and p53 in non-small cell lung carcinoma and normal lung tissue from 50 patients. The relationships between expressions of the Glutathione-S-transferase isoenzymes and some clinicopathological features were also examined. Expression of glutathione-S-transferase pi, mu, alpha, theta and p53 was assessed by immunohistochemistry for primary lung carcinomas of 50 patients from the Sanitarium Education and Research Hospital, Ankara lung cancer collection. The relationships betw

Background: Epidemiological studies observing inconsistent associations of telomere length (TL) with ischemic stroke (IS) are susceptible to bias according to reverse causation and residual confounding. We aimed to assess the causal association between TL, IS, and the subtypes of IS, including large artery stroke (LAS), small vessel stroke (SVS), and cardioembolic stroke (CES) by performing a series of two-sample Mendelian randomization (MR) approaches. Methods: Seven single nucleotide polymorphisms (SNPs) were involved as candidate instrumental variables (IVs), summarized from a genome-wide m
