Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina

Description: Article describes experiment in which mature adult zebrafish (Danio rerio) were subjected to a swimming performance test that allowed separation into low swimming stamina or high swimming stamina groups in order to determine if inherited traits that support enhanced swimming stamina in offspring appear only in juveniles and/or adults, or if these traits actually appear earlier in the morphologically quite different larvae.

Elevated CO2 increases energetic cost and ion movement in the marine fish intestine

Description: Article describes study which aimed to gain resolution in assessing the energetic demand associated with acid-base regulation by examining ion movement and O2 consumption rates of isolated intestinal tissue from Gulf toadfish acclimated to control or 1900 μatm CO2 (projected for year 2300).

Effect of selection for commercially productive traits on the plasticity of cardiovascular regulation in chicken breeds during embryonic development

Description: Article investigates basic cardiovascular physiology in the Red Junglefowl, the broiler, and the White Leghorn breeds at 90% of incubation. The authors aimed to identify breed-specific features of arterial blood pressure and heart rate as well as the physiological mechanisms regulating them. They concluded that selection for rapid growth shifts cardiovascular regulatory plasticity to emphasize mechanisms that modulate pressure, and that selection for egg-laying capacity emphasizes mechanisms th… more

Thymoquinone overcomes chemoresistance and enhances the anticancer effects of bortezomib through abrogation of NF-κB regulated gene products in multiple myeloma xenograft mouse model

Description: Article investigates whether thymoquinone (TQ), a bioactive constituent of black seed oil, could suppress the proliferation and induce chemosensitization in human myeloma cells and xenograft mouse model. Overall, the results demonstrate that TQ can enhance the anticancer activity of bortezomib in vitro and in vivo and may have a substantial potential in the treatment of MM.

Association of Host and Microbial Species Diversity across Spatial Scales in Desert Rodent Communities

Description: Article describes study in which researchers employed a natural gradient of rodent species richness and quantified bacterial communities in rodent blood at several hierarchical spatial scales to test the hypothesis that associations between host and microbial species diversity will be positive in communities dominated by organisms with broad niches sampled at large scales.

Negative Regulation of Signal Transducer and Activator of Transcription-3 Signalling Cascade by Lupeol Inhibits Growth and Induces Apoptosis in Hepatocellular Carcinoma Cells

Description: In this article, the authors evaluate the effect of lupeol on STAT3 signalling cascade and its regulated functional responses in hepatocellular carcinoma (HCC) cells. Constitutive activation of signal transducer and activator of transcription signalling 3 (STAT3) has been linked with survival, proliferation and angiogenesis in a wide variety of malignancies including HCC. Lupeol exhibited its potential anticancer effects in HCC through the downregulation of STAT3-induced pro-survival signalling… more

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control

Description: 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

Description: 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 pol… more

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

Description: 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)

Description: 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 pe… more

Technical Memorandum: Lewisville Lake Watershed Protection and Management Strategies

Description: With a current population of just over half a million and a 2030 projected population of approximately one million, expansion throughout Denton County shows no sign of slowing down (NCTCOG). Increasingly, freshwater resources are also facing increased pressure from this urban expansion. Effective assessment and management techniques are necessary to protect the diversity of ecosystem services found within fluvial ecosystems and to mitigate current and future conditions of environmental stresso… more
