Isorhamnetin Inhibits Proliferation and Invasion and Induces Apoptosis through the Modulation of Peroxisome Proliferator-activated Receptor γ Activation Pathway in Gastric Cancer

Description: Article investigating the potential effects of isorhamnetin (IH), a 3′-O-methylated metabolite of quercetin on the peroxisome proliferator-activated receptor γ (PPAR-γ) signaling cascade using proteomics technology platform, GC cell lines, and xenograft mice model. The study y proposes a novel agent for gastric cancer treatment.

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

Description: This article explores swimming stamina in fish. Mature adult zebrafish (Danio rerio) were subjected to a swimming performance test and then bred within performance groups to discover if enhanced swimming stamina in offspring appears only in juveniles/adults, or if these traits appear as early as larvae.

In situ cardiac performance of Atlantic cod (Gadus morhua) at cold temperatures: long-term acclimation, acute thermal challenge and the role of adrenaline

Description: This article measures the cardiac performance of Newfoundland Atlantic cod (Gadus morhua). The results: (1) show that maximum performance of the isolated cod heart is not compromised by exposure to cold temperatures; and (2) support data from other studies, which show that, in contrast to salmonids, cod cardiac performance/myocardial contractility is not dependent upon humoral adrenergic stimulation.

Constraints-based stoichiometric analysis of hypoxic stress on steroidogenesis in fathead minnows, Pimephales promelas

Description: This article presents a study in which an in silico genome-scale metabolic model of steroidogenesis is used to investigate the effects of hypoxic stress on steroid hormone productions in fish. This article introduces a powerful model for pathway analysis that can lend insights on the effects of various stressor scenarios on metabolic functions.

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs

Description: This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.

Space-charge-based electrostatic plasma confinement involving relaxed plasma species

Description: In this article, a numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potential is carried out for a non-neutral plasma that follows a Boltzmann density distribution.

Low-temperature UV photoluminescence of ion beam synthesized Si nanoclusters embedded in Si

Description: This article explores Ultraviolet (UV) photoluminescence (PL) data taken on a double Au implanted Si matrix and studied over a wide temperature range of 28-220K. The results of this study at lower temperatures indicate the emission to be coming from Si nanoclusters (NCs) embedded in the matrix.

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.

Statistical assumptions of substantive analyses across the general linear model: a mini-review

Description: This article seeks to support researchers by concisely reviewing key statistical assumptions associated with substantive statistical tests across the general linear model. Additionally, the article reviews techniques to check for statistical assumptions and identifies remedies and problems if data do not meet the necessary assumptions.

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

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.

The Implications of Cancer Stem Cells for Cancer Therapy

Description: This review summarizes the characteristics, evidences and development of CSCs, as well as implications and challenges for cancer treatment. Surgery, radiotherapy and chemotherapy are universally recognized as the most effective anti-cancer therapies. Recent studies have showed that cancer stem cells (CSCs), a small subpopulation of tumor cells, can generate bulk populations of nontumorigenic cancer cell progeny through the self-renewal and differentiation processes.
