In this paper, the problem of finding the set of all real solutions to a system of n nonlinear general form algebraic equations contained in a given n-dimensional box (the global analysis problem) is considered. A new iterative interval method for solving the global analysis problem is suggested. It is based on the following techniques: (i) transformation of the original system into an augmente...

BACKGROUND The risk effect of APOE epsilon 4 allele for Alzheimer's disease is acknowledged, whereas the putative protective effect of epsilon 2 allele remains in debate. OBJECTIVES To investigate whether those inconsistent findings may be attributable to differences in age and sex composition of the study populations. METHODS A community dementia free cohort (n = 985) aged > or =75 years w...

The aim of this study was to determine whether gamma-rays affect differentiation in mouse epidermal cells. After a pre-treatment with the PKC inhibitor staurosporin (STS) or 1-(5-isoquinolinesulfomyl)-2-methylpiperazine (H7), gamma-rays were irradiated with or without an elevation of 0.12 mM Ca2+ and expressions of differentiation markers and each PKC isozyme were examined in normal primary and...

Collagen is a key structural protein in the extracellular matrix of many tissues. It provides biological tissues with tensile mechanical strength and is enzymatically cleaved by a class of matrix metalloproteinases known as collagenases. Collagen enzymatic kinetics has been well characterized in solubilized, gel, and reconstituted forms. However, limited information exists on enzyme degradation...

Hepatitis B virus (HBV) replicates by reverse transcription of an RNA intermediate, the pregenomic RNA. The first step of HBV genome replication is the encapsidation of the pregenomic RNA encoding the encapsidation signal, termed epsilon, into the core particles, which is preceded by recognition and binding of HBV DNA polymerase to epsilon. The pregenomic RNA contains two identical epsilon elem...

The hepatitis B viruses replicate by reverse transcription of an RNA pregenome by using a virally encoded polymerase. A key early step in replication is binding of the polymerase to an RNA stem-loop (epsilon) of the pregenome; epsilon is both the RNA encapsidation signal and the origin of reverse transcription. Here we provide evidence that this interaction is also key to the development of enz...

This paper proposes an improved epsilon constraint-handling mechanism, and combines it with a decomposition-based multi-objective evolutionary algorithm (MOEA/D) to solve constrained multi-objective optimization problems (CMOPs). The proposed constrained multi-objective evolutionary algorithm (CMOEA) is named MOEA/D-IEpsilon. It adjusts the epsilon level dynamically according to the ratio of fe...

Designing and producing a proper fusion construction is the most important problem of producing large quantities of a properly folded functional protein. This construction should have all necessary components of a real gene. A good designed fusion gene construction could be cloned into a good and suitable host. Clostridium perfringens is an important pathogen of humans and livestock and produce...

Abstract We prove a Liouville-type theorem for the linearly perturbed Paneitz equation: For $\epsilon>0$ small enough, if $u_\epsilon $ is positive smooth solution of $$ \begin{align*} &P_{S^3} u_\epsilon+\epsilon u_\epsilon=-u_\epsilon^{-7} \qquad \textrm{on}\ S^3,\end{align*}$$where $P_{S^3}$ operator round metric $g_{S^3}$, then constant. This confirms conjecture proposed by Hang ...
