Purpose

To compare the risk of developing subsequent primary lung cancer among cervical cancer patients and the general population.

Methods

Several databases were searched from inception to April 25, 2023. The standard incidence ratios (SIRs) with 95% confidence intervals (CIs) were combined to identify the risk for second primary lung cancer after cervical carcinoma. Subgroup analyses based on the follow-up period, age, degree of malignancy and source of SIR were conducted. Читать дальше...

by Xiaohui Huang, Lizhen Gao

The thermal effect mainly includes boundary temperature stratification and the local thermal effect. The combined effect of these factors on flow and dispersion in a bi-dimensional canyon was investigated by the RANS and LES methods to evaluate their performance. The results, including the flow field, turbulent kinetic energy, temperature, heat flux, pollutant concentration and fluxes, were compared with the data from wind tunnel experiments. The comparison results... Читать дальше...

by Rhiannon E. Cecil, Deborah R. Yoder-Himes

Exploration of interspecies interactions between microorganisms can have taxonomic, ecological, evolutionary, or medical applications. To better explore interactions between microorganisms it is important to establish the ideal conditions that ensure survival of all species involved. In this study, we sought to identify the ideal biotic and abiotic factors that would result in high co-culture viability of two interkingdom species, Pseudomonas aeruginosa and Acanthamoeba castellanii...
