Design, Synthesis and Biological Evaluation of 2-Phenyl Indole Analogues of OXi8006 as Colchicine Site Inhibitors of Tubulin Polymerization and Vascular Disrupting Agents.

Inhibitors of tubulin polymerization represent a promising therapeutic approach for the treatment of solid tumors. Molecules that bind to the colchicine site are of interest as they can function with a dual mechanism of action as both potent antiproliferative agents and tumor-selective vascular disrupting agents (VDAs). One such example is a 2-aryl-3-aroyl-indole molecule (OXi8006) from our laboratory that demonstrates potent inhibition of tubulin polymerization and strong antiproliferative activity (cytotoxicity) against a variety of human cancer cell lines.

Efficacy of same-day versus next-day administration of pegfilgrastim for the prevention of chemotherapy-induced febrile neutropenia in breast cancer patients receiving dose-dense doxorubicin and cyclophosphamide: A retrospective multi-site analysis.

Introduction: Administering pegfilgrastim on the same day as chemotherapy can improve patient satisfaction through convenience and may increase the utilization of cost-effective biosimilars compared to next-day administration, but the effect on clinical outcomes with commonly used breast cancer regimens is unclear.

Methods: This multi-site, retrospective cohort study included breast cancer patients age 18 years or older who received dose-dense doxorubicin and cyclophosphamide (ddAC) and pegfilgrastim between 1 June 2016 and 31 May 2020. Pegfilgrastim was given on the same day as chemotherapy at one site and the day after chemotherapy at the other two sites.

The Impact of COVID-19: Nurses Occupational Stress and Strategies to Manage It.

Objective: The aim of this study was to explore the occupational stress perception of nurses and how they manage it during the COVID-19 pandemic.

Background: The management of occupational stress is a key factor in promoting nurses' well-being.

Methods: A descriptive cross-sectional study was conducted.

Long-distance fiber optic vibration sensing using convolutional neural networks as real-time denoisers.

A long distance range over tens of kilometers is a prerequisite for a wide range of distributed fiber optic vibration sensing applications. We significantly extend the attenuation-limited distance range by making use of the multidimensionality of distributed Rayleigh backscatter data: Using the wavelength-scanning coherent optical time domain reflectometry (WS-COTDR) technique, backscatter data is measured along the distance and optical frequency dimensions. In this work, we develop, train, and test deep convolutional neural networks (CNNs) for fast denoising of these two-dimensional backscattering results.

[PGE1-assisted treatment of microcirculation disturbance in complicated falciparum malaria].

This article reports the course of a complicated malaria in a 41-year-old male patient. After spending several months in Mali, the patient decompensated shortly after onset of the first symptoms. Under the signs of a multi-organ failure and with an initial parasitic load of 25%, the patient developed a microcirculation disturbance in the acra.
