**VictBennet**9 minutes ago - Topic: MicrobiologyIon channel expression and activity may be affected during tumor development and cancer growth. Activation of potassium (K+) channels in human breast cancer cells is reported to be involved in cell cycle progression. In this study, we investigated the effects of docetaxel on the delayed rectifier potassium current (IK) and the ATP-sensitive potassium current (IKATP) in two human breast cancer c...

**rhstaathaff**9 minutes ago - Topic: HealthNicotinamide (pyridine-3-carboxamide), an amide, active form of vitamin B3, is used to treat a variety of dermatologic conditions, including skin cancer. Limited data are available regarding the adverse effects of nicotinamide in the literature. Here, we report a case of gingivitis associated with nicotinamide. A 35-year-old female patient was referred to the Department of Periodontics for the ...

**DarrEva**10 minutes ago - Topic: HealthThis paper investigates the notion of treatment threshold for preventive treatment with potential side effects in the context of changes in risk. Changes in risk are defined by the concept of nth-order stochastic dominance and concern the effectiveness of preventive treatment, side effects, severity of the potential disease, and comorbidity risk. The impact of a riskier environment on the proba...

**blaiail**10 minutes ago - Topic: AstronomyThe success of precision cosmology depends not only on accurate observations, but also on the theoretical model --- which must be understood to at least the same level of precision. Subtle relativistic effects can lead to biased measurements if they are neglected. One such effect gives a systematic shift in the distance-redshift relation away from its background value, due to the non-linear rel...

**catisoya25**13 minutes ago - Topic: SurgeryEarly recognition and, where possible, avoidance of risk factors that contribute to the development of poststernotomy mediastinitis (PSM) form the basis for successful prevention. Once the presence of PSM is diagnosed, the known risk factors have been shown to have limited influence on management decisions. Evidence-based knowledge on treatment decisions, which include the extent and type of su...

**gmahommody**14 minutes ago - Topic: PhysicsThe perihelion precession and deflection of light have been investigatedin the 4-dimensional general spherically symmetric spacetime, and the masterequation is obtained. As the application of this master equation, the Reissner-Nordstorm-AdS solution and Clifton-Barrow solution in gravity have been taken as examples. We find that both the electric charge and gravitycan affect the perihelion prec...

**957896**14 minutes ago - Topic: PhysicsAt very initial stage of relativistic heavy ion collisions a wave of quark-gluon matter is produced from the break-up of the strong color electric field and then thermalizes at a short time scale (1 fm/c). However, the quark-gluon plasma (QGP) system is far out of chemical equilibrium, especially for the heavy quarks which are supposed to reach chemical equilibrium much late. In this paper a ...

**irecoggriy**16 minutes ago - Topic: PhysicsCo and Cd have been codoped in ZnO using a simple solid state reaction technique to synthesize dilute magnetic oxide semiconductors of composition Zn0.9Co0.1−xCdxO ( with an increment of 0.02). Hexagonal wurtzite structure has been obtained for samples up to , using X-ray diffractometry. However, at and 0.1, secondary peak of CdO is observed. Raman spectra of the samples have been obtained in...

**m4regald**16 minutes ago - Topic: PhysicsMyelin is an insulating, multi-lamellar membrane structure wrapped around selected nerve axons. Increasing the speed of nerve impulses, it is crucial for the proper functioning of the vertebrate nervous system. Human neurodegenerative diseases, such as multiple sclerosis, are linked to damage to the myelin sheath through demyelination. Myelin exhibits a well defined subset of myelin-specific pr...

**LucianoSam**17 minutes ago - Topic: MathematicsWe study, using Hepp's method, the propagation of coherent states for a general class of self interacting bosonic quantum field theories with spatial cutoffs. This includes models with non-polynomial interactions in the field variables. We show indeed that the time evolution of coherent states, in the classical limit, is well approximated by time-dependent affine Bogoliubov unitary transformati...

**glniwtan**17 minutes ago - Topic: MathematicsIn this paper we study Ulam's cellular automaton, a nonlinear almost equicontinuous two-dimensional cell-model of crystalline growths. We prove that Ulam's automaton contains a linear chaotic elementary cellular automaton (Rule 150) as a subsystem. We also study the application of the inverse ultradiscretization, a method for deriving partial differential equations from a given cellular automat...

**ChaimDanie**17 minutes ago - Topic: MathematicsWe consider the high frequency Helmholtz equation with a variable refraction index n 2 ( x ) ( x ∈ ℝ d ), supplemented with a given high frequency source term supported near the origin x = 0. A small absorption parameter α ε > 0 is added, which prescribes a radiation condition at infinity for the considered Helmholtz equation. The semi-classical parameter is ε > 0. We let ε and α ε go...

Because of the presence of these sequestering agents, metallic ions cannot be readily precipitated by alkalinity, makin...
