Odor-mediated contextual learning induced memory consolidation and hippocampus development in neonate rat.

The hippocampus in neonatal rats is not fully developed after birth, and the effect of odor-aversion learning on memory consolidation in the immature hippocampus is not well understood. Therefore, the aim of the present study was to explore the effects of odor-aversion learning in neonatal rats on memory consolidation and neurodevelopment in the immature hippocampus. The effect of hippocampal-induced learning was measured at two different developmental stages using the Y-maze and c-Fos protein levels.

Effects of bone marrow mesenchymal stem cells transfected with Ang-1 gene on hyperoxia-induced optic nerve injury in neonatal mice.

Optic nerve injury triggered retinal ganglion cell (RGC) death and optic nerve atrophy lead to visual loss. Bone marrow mesenchymal stem cells (BMSCs) are stromal cells, capable of proliferating and differentiating into different types of tissues. This aims of this study is to investigate the role of BMSCs transfected with angiopoietin-1 (Ang-1) in optic nerve injury induced by hyperoxia in a neonatal mice model.

Trace elements in four freshwater fish from a mine-impacted river: spatial distribution, species-specific accumulation, and risk assessment.

The concentrations of 16 elements (Mg, Al, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Sr, Cd, Ba, and Pb) were determined in four fish species (Carassius auratus, Squaliobarbus curriculus, Pelteobagrus fulvidraco, and Silurus asotus) collected in the Xiang River, a mine-impacted river in Southern China. The mean values of the elements analyzed in fish muscles were in the decreasing order of Mg > Ca > Zn > Fe > Sr > Al > Cu > Mn > Ba > As > Cr > Pb > Ni > V > Co > Cd. The concentrations of Mg, Ca, Sr, Ba, and Cu in omnivorous species were found to be significantly higher (p < 0.

Species-specific bioaccumulation and correlated health risk of arsenic compounds in freshwater fish from a typical mine-impacted river.

Arsenic (As) speciation and bioaccumulation in fish muscle tissues have been intensively investigated in marine ecosystem. However, little is known about these in freshwater fish. In this study, freshwater fish including 120 specimens and 8 species were collected from the Xiang River, a typical mine-impacted river in China.

Equivalent conditions and applications of a class of Hilbert-type integral inequalities involving multiple functions with quasi-homogeneous kernels.

Let satisfy for . With this integral kernel, by using the method and technique of weight coefficients, the equivalent conditions and the best constant factors for the validity of Hilbert-type integral inequalities involving multiple functions are discussed. Finally, the applications of the integral inequalities are considered.

Variational solutions and random dynamical systems to SPDEs perturbed by fractional Gaussian noise.

This paper deals with the following type of stochastic partial differential equations (SPDEs) perturbed by an infinite dimensional fractional Brownian motion with a suitable volatility coefficient Φ: dX(t) = A(X(t))dt+Φ(t)dB (H) (t), where A is a nonlinear operator satisfying some monotonicity conditions. Using the variational approach, we prove the existence and uniqueness of variational solutions to such system. Moreover, we prove that this variational solution generates a random dynamical system.

Existence and uniqueness of solution for a class of stochastic differential equations.

A class of stochastic differential equations given by dx(t) = f(x(t))dt + g(x(t))dW(t),  x(t 0) = x 0,  t 0 ≤ t ≤ T < +∞, are investigated. Upon making some suitable assumptions, the existence and uniqueness of solution for the equations are obtained. Moreover, the existence and uniqueness of solution for stochastic Lorenz system, which is illustrated by example, are in good agreement with the theoretical analysis.
