Impulse and DC breakdown strength of polypropylene thin film

Physics of Complex Systems, 2020
The paper presents the results of a study of the electric strength of a polypropylene film with a thickness of 2 μm. The breakdown voltage of the film was determined under the influence of electric pulses and with a slowly increasing voltage. The rate of

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Development and Validation of an Analytical Procedure for the Quantitative Determination of Total Flavonoids in Red-Stem Buckwheat Herb (Fagopyrum rubricaulis) by Spectrophotometry

Регуляторные исследования и экспертиза лекарственных средств
INTRODUCTION. Red-stem buckwheat (Fagopyrum rubricaulis, Polygonaceae family) is characterised by a high content of flavonoids, primarily rutin. The aerial parts of the plant also contain quercetin, isoquercetin, orientin, vitexin, isoorientin, and other

Calculation and analysis of torsional vibration of electrical propulsion system under a short-circuit-induced impulse load

Zhongguo Jianchuan Yanjiu, 2020
Objectives For an electrical propulsion system, the transient torque induced by short-circuit faults is so large that it will exert a greater impact on the safety of shipboard electric propulsion system.

Analysis of the booster DC to DC converter with feedback [PDF]

, 2014
The field effect power transistors are used in many applications in electromechanical systems. Control of the field effect power transistors requires isolated 5V control signals and isolated 12V DC sources.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

An algebraic approach to the minimum-cost multi-impulse orbit transfer problem [PDF]

, 2015
We present a purely algebraic formulation (i.e. polynomial equations only) of the minimum-cost multi-impulse orbit transfer problem without time constraints, while keeping all the variables with a precise physical meaning.

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
