Deubiquitinase USP38 Stabilizes PLK1 Expression to Boost DNA Damage Repair in Ovarian Cancer
The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Ovarian cancer (OC) is one of the most prevalent and severe gynecological malignant tumors. DNA damage repair (DDR) is essential in maintaining genome stability. This study aims to investigate the effects and mechanisms of USP38 and PLK1 on DNA damage repair and malignant behavior in OC cells.

Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]
The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.

Biomonitoring of the genotoxic potential of aqueous extracts of soils and bottom ash resulting from municipal solid waste incineration, using the comet and micronucleus tests on amphibian (Xenopus laevis) larvae and bacterial assays (MutatoxR and Ames tests) [PDF]
, 2006 The management of contaminated soils and wastes is a matter of considerable human concern. The present study evaluates the genotoxic potential of aqueous extracts of two soils (leachates) and of bottom ash resulting from municipal solid waste ...

Journal of Polymer Science, EarlyView.This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Phytotherapy Research, EarlyView.ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Effects of monomer shape on the formation of aggregates from a power law monomer distribution
New Journal of Physics, 2013 The coagulation of dust aggregates is an important process in many physical systems such as the Earth's upper atmosphere, comet tails and protoplanetary discs.
