Tolerance towards environmental stress has been frequently considered as one of the key determinants of invasion success. However, empirical evidence supporting the assumption that invasive species can better endure unfavorable conditions compared with native species is limited and has yielded opposing results. In this study, we examined the tolerance to different stress conditions (thermal stress and trace metal zinc pollution stress) in two phylogenetically related and functionally similar freshwater bivalve species, the native Anodonta anatina and the invasive Sinanodonta woodiana. We assessed potential differences in response to stress conditions using several cellular response assays: efficiency of the multixenobiotic resistance mechanism, respiration estimate (INT reduction capacity), and enzymatic biomarkers. Our results demonstrated that the invasive species overall coped much better with unfavorable conditions. The higher tolerance of S. woodiana was evident from (i) significantly decreased Rhodamine B accumulation indicating more efficient multixenobiotic resistance mechanism; (ii) significantly higher INT reduction capacity and (iii) less pronounced alterations in the activity of stress-related enzymes (glutathione-S-transferase, catalase) and of a neurotoxicity biomarker (cholinesterase) in the majority of treatment conditions in both stress trials. Higher tolerance to thermal extremes may provide physiological benefit for further invasion success of S. woodiana in European freshwaters, especially in the context of climate change.

Background: Biliary leakage is a serious complication of hepato-pancreato-biliary operations, increasing morbidity and mortality, and challenging clinicians.
Objective: This study aims to evaluate the incidence of bilioenteric anastomotic leakage, treatment options, and their outcomes at a high-volume tertiary referral center.
Methods: A retrospective cohort study was conducted to analyze the outcomes of patients who underwent biliary anastomosis formation between 2016 and 2021.

Conventional treatment of prostate cancer need more specificity, and higher efficiency. The present work is the first attempt to utilize hydrogel-loaded carvacrol-based chemotherapy with fractionated photothermal therapy (F-PTT) using a 635 nm laser for its treatment. Gold nanobipyramids (AuNBPs) were used as drug carrier and photosensitizer.

Background: Real-world outcomes, especially patterns of failure, are limited for patients with muscle-invasive bladder cancer (MIBC) treated with trimodality therapy (TMT). We aim to evaluate patterns of failure after TMT for MIBC in a typical heterogeneous population.
Methods: In the national Veterans Affairs database, patients with urothelial histology, MIBC (T2-4a/N0-3/M0) who underwent definitive intent TMT between 2000-2018.

Background: As the primary cause of various preventable illnesses, smoking results in approximately five million premature deaths each year in the US and a multitude of adults living with serious illness. The majority of smokers know the health risks associated with smoking and intend to quit. However, quitting is very difficult partly because of insomnia and stress associated with it.
