The Association of Anemia on Non-AIDS Defining Cancer and Subsequent Survival among People with HIV following Antiretroviral Initiation.

Background: The association of anemia as a predictive and prognostic indicator of non-AIDS defining cancer (NADC) among people with HIV (PWH) remains unknown. We evaluated the presence of anemia and its severity as a predictor of NADC and 5-year all-cause survival following an NADC diagnosis among PWH who had initiated antiretroviral therapy.

Setting: North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD).

Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology.

Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among researchers in the decisions they make regarding statistical analyses. A growing array of studies has explored this analytical variability in different fields and has found substantial variability among results despite analysts having the same data and research question.

Confined Water for Catalysis: Thermodynamic Properties and Reaction Kinetics.

Water is a salient component in catalytic systems and acts as a reactant, product and/or spectator species in the reaction. Confined water in distinct local environments can display significantly different behaviors from that of bulk water. Therefore, the wide-ranging chemistry of confined water can provide tremendous opportunities to tune the reaction kinetics.

A novel DNA repair protein, N-Myc downstream regulated gene 1 (NDRG1), links stromal tumour microenvironment to chemoresistance.

Unlabelled: In pancreatic ductal adenocarcinoma cancer (PDAC) drug resistance is a severe clinical problem and patients relapse within a few months after receiving the standard-of-care chemotherapy. One contributing factor to treatment resistance is the desmoplastic nature of PDAC; the tumours are surrounded by thick layers of stroma composing up to 90% of the tumour mass. This stroma, which is mostly comprised of extracellular matrix (ECM) proteins, is secreted by cancer-associated fibroblasts (CAFs) residing in the tumour microenvironment.
