Description: This article presents herpetofaunal observations from Limnos and Agios Efstratios, two Asia Minor continental shelf islands in the Aegean Sea. Comprehensive surveys over 88 days in total on Limnos, over a period of nine years, consisted mainly of visual encounter surveys and road cruised observations, revealed the presence of three species of amphibians and twelve species of reptiles, including two new species records for the island (Malpolon insignitus and Pelobates syriacus). The results of t… more

EMOTION-III Model: A Theoretical Framework for Social Empathic Emotions in Autonomous Control Systems

Description: In this article, a theoretical model of social empathic emotion is derived based on the principles of survival by extending the maximization of self-gains to include others as an extended-self. This extended-self model of optimization for survival provides the computational mechanisms in the optimization process to maximize self-gains without minimizing the gains (or maximizing losses) for the other individuals. Thus, it can resolve conflicts in a competitive environment, and change the social … more

The Differences between NAD-dependent malic enzyme and NADP-dependent malic enzyme Subtypes of C4 Photosynthesis: More than Decarboxylating Enzymes

Description: Article addresses the differences in evolutionary scenario, leaf anatomy, and especially C4 metabolic flow, C4 transporters, and cell-specific function deduced from recently reported cell-specific transcriptomic, proteomic, and metabolic analyses of NAD-dependent malic enzyme (NAD-ME) and NADP-dependent malic enzyme (NADP-ME) subtypes.

Metabolomics as a hypothesis-generating functional genomics tool for the annotation of Arabidopsis thaliana genes of “unknown function”

Description: Article describes the analysis of Arabidopsis metabolomics data sets acquired by a consortium that includes five analytical laboratories, bioinformaticists, and biostatisticians, which aims to develop and validate metabolomics as a hypothesis-generating functional genomics tool.

Biochemical and molecular-genetic characterization of SFD1’s involvement in lipid metabolism and defense signaling

Description: Article describes study which sought to to determine if the dihydroxyacetone phosphate (DHAP) reductase activity and chloroplast localization are required for the Arabidopsis thaliana SFD1 (suppressor of fatty acid desaturase deficiency1) gene’s involvement in galactolipid metabolism and systemic acquired resistance (SAR) signaling.

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).

SPHK1 regulates proliferation and survival responses in triple-negative breast cancer

Description: Article describes study suggesting that the inhibation of sphingosine kinase 1 (SPHK1) can attenuate ERK1/2 and AKT signaling and reduce growth of triple-negative breast cancer (TNBC) cells in vitro and in a xenograft SCID mouse model.

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.

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

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.

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.
