The embryonic environment is critical for the development of many ectothermic vertebrates, which makes them highly vulnerable to environmental change. Changes in temperature and moisture, in particular, are known to influence embryo survival and offspring phenotypes. While most papers concerning phenotypic development of terrestrial ectotherms focus on the role of temperature on eggs and embryos, the comparatively small number of studies on the effects of substrate moisture are well suited for quantitative analysis aimed at guiding future research.

Introduction: With the implementation of low-dose computed tomography screening, multiple pulmonary tumor nodules are diagnosed with increasing frequency and the selection of surgical treatments versus systemic therapies has become challenging on a daily basis in clinical practice. In the presence of multiple carcinomas, especially adenocarcinomas, pathologically determined to be of pulmonary origin, the distinction between separate primary lung carcinomas (SPLCs) and intrapulmonary metastases (IPMs) is important for staging, management, and prognostication.

Methods: We systemically reviewed various means that aid in the differentiation between SPLCs and IPMs explored by histopathologic evaluation and molecular profiling, the latter includes DNA microsatellite analysis, array comparative genomic hybridization, TP53 and oncogenic driver mutation testing and, more recently, with promising effectiveness, next-generation sequencing comprising small- or large-scale multi-gene panels.

An overview of immune checkpoint inhibitor toxicities in bladder cancer.

Toxicol Rep

December 2024

Department of Medical Oncology, Medway NHS Foundation Trust, Windmill Road, Gillingham ME7 5NY, UK.

Bladder cancer is the tenth most prevalent malignancy worldwide, with a significant mortality burden. Urothelial carcinoma (UC) is the most common histological subtype, and treatment options are guided by whether the disease is muscle-invasive (MIBC) or non-muscle-invasive (NMIBC), with subsequent risk group stratification. The growing popularity of immune checkpoint inhibitors (ICIs) to treat MIBC and NMIBC as either monotherapy or combined with intravesical agents, may radically change the treatment paradigm of UC.
