Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control (open access)

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control

In this article, a theoretical understanding is developed of the single-particle reflection properties of a force field, considering the incident charged particles to have a non-drifting, isotropic velocity distribution. Classical trajectory Monte Carlo simulations and analytical modeling are employed. The initiation of an experimental effort to study force fields is described.

Structural Consideration in Designing Organotin Polyethers to Arrest the Growth of Breast Cancer Cells In Vitro (open access)

Structural Consideration in Designing Organotin Polyethers to Arrest the Growth of Breast Cancer Cells In Vitro

The article looks at antitumor activity using a matched pair of cell lines MDA-MB-231 cells that are estrogen-independent, estrogen receptor negative and MCF-7 cells, a cell line that is estrogen receptor (ER) positive. Those polyethers that contained a O-phenyl unit were able to significantly inhibit the non-estrogen sensitive cell line but were much less effective against the estrogen sensitive cell line; that is, the human breast cancer cell line MDA-MB-231 showed better test results for polymers derived from diols containing the O-phenyl moiety than the breast cancer cell line MCF-7, a well-characterized estrogen receptor positive control cell line.

Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers (open access)

Antiviral Activity of Metal-Containing Polymers—Organotin and Cisplatin-Like Polymers

This article examines the use of metal-containing polymers as a novel class of antivirals. Polymers containing platinum and to a lesser extent tin, have repeatedly demonstrated antitumor activity in vitro and in vivo against a variety of cell and tumor types. The mechanisms responsible for the antitumor activity include inducing a delay in cell proliferation and sister chromatid exchanges blocking tumor growth.

The First Stalin Mass Operation (1927) (open access)

The First Stalin Mass Operation (1927)

This article based on new archival documents introduces a new episode of mass operations, which took place in June and July of 1927 and was directed against the broad group of “anti-Soviet” forces. It preceded many practices of mass terror of the 1930s with judicial and extra-legal mechanisms. The goal of this article is to explain motivations, justifications, and mechanisms of this repressive campaign and to put this episode in the wider context of Soviet terror. Facing the combination of a perceived danger of war and real internal social hostility expressed in broad defeatism, both threatening the perpetuation of their governmental powers, authorities resorted to repressions. The 1927 episode highlights the factor of a perceived threat of war as a crucial motivating element in Soviet repressive tactics.
