Origin of Persisting Photoresponse of One-Year Aged Two-Dimensional Lead Halide Perovskites Stored in Air under Dark Conditions.

Two-dimensional halide perovskites are promising for advanced photonic, optoelectronic, and photovoltaic applications. However, their long-term stability is still a critical factor limiting their implementation into further commercial applications. Here, we present an environmental stability analysis of BA(MA)PbI (BA = CHN, MA = CHN) two-dimensional perovskites with the lowest quantum well thicknesses of = 1 and = 2, after 1 year of aging under ambient humidity, oxygen content, and light conditions.

Contrast Administration Impacts CT-Based Radiomics of Colorectal Liver Metastases and Non-Tumoral Liver Parenchyma Revealing the "Radiological" Tumour Microenvironment.

The impact of the contrast medium on the radiomic textural features (TF) extracted from the CT scan is unclear. We investigated the modification of TFs of colorectal liver metastases (CLM), peritumoral tissue, and liver parenchyma. One hundred and sixty-two patients with 409 CLMs undergoing resection (2017-2020) into a single institution were considered.

Radiomics of Liver Metastases: A Systematic Review.

Multidisciplinary management of patients with liver metastases (LM) requires a precision medicine approach, based on adequate profiling of tumor biology and robust biomarkers. Radiomics, defined as the high-throughput identification, analysis, and translational applications of radiological textural features, could fulfill this need. The present review aims to elucidate the contribution of radiomic analyses to the management of patients with LM.

[Modern methods of treatment of Morgagni-Larrey hernia].

In the clinic 3 patients were treated for inborn diaphragmatic Morgagni-Larrey hernia. The modern videoendoscopic methods application, including laparoscopy, have permitted to improve significantly the operation results and security, to reduce the patients stationary treatment duration. Since the disease is diagnosed it is necessary to perform operative intervention for the severe complications prophylaxis.
