Treatment with fixed appliances and clear plastic appliances. Evaluation of results

Aims: The retrospective study assessed outcomes of orthodontic treatment using fixed appliance and clear plastic aligner with PAR index, and compared effectiveness of the therapy with TEI (treatment efficiency index). Another aim was to compare the number of occlusal contacts and assess ...

Diet Rich in Animal Protein Promotes Pro-inflammatory Macrophage Response and Exacerbates Colitis in Mice

Diet is a major factor determining gut microbiota composition and perturbances in this complex ecosystem are associated with the inflammatory bowel disease (IBD). Here, we used gnotobiotic approach to analyze, how interaction between diet rich in proteins and gut microbiota influences the&#x...

Metabolomic Study of Obesity and Its Treatment with Palmitoylated Prolactin-Releasing Peptide Analog in Spontaneously Hypertensive and Normotensive Rats

In this study, the combination of metabolomics and standard biochemical and biometric parameters was used to describe the metabolic effects of diet-induced obesity and its treatment with the novel antiobesity compound palm11-PrRP31 (palmitoylated prolactin-releasing peptide) in spontaneously hypertensive r...

On partially free boundary solutions for elliptic problems with non-lipschitz nonlinearities

We show that the elliptic equation with non-Lipschitz right-hand side, considered on a smooth star-shaped domain Ω subject to zero Dirichlet boundary conditions, might possess a nonnegative ground state solution which violates Hopf’s maximum principle only on a nonempty subset Γ of the&...

On digraphs of excess one

A digraph in which, for every pair of vertices u and v (not necessarily distinct), there is at most one walk of length at most k from u to v is called a k-geodetic digraph. The order N(d,k) of a k-geodetic digraph of minimum out-degree d is at least th...

Minor lipids profiling in subcutaneous and epicardial fat tissue using LC/MS with an optimized preanalytical phase

Analysis of bioactive lipids in adipose tissue could lead to better understanding of the pathogenesis of obesity and its complications. However, current MS methods are limited by a high content of triacylglycerols (TAGs), which markedly surpasses the amount of other lipids and suppresse...

Nonuniqueness of implicit lattice Nagumo equation

We consider the implicit discretization of Nagumo equation on finite lattices and show that its variational formulation corresponds in various parameter settings to convex, mountain-pass or saddle-point geometries. Consequently, we are able to derive conditions under which the implicit discretization&...

On semiregularity of mappings

There are two basic ways of weakening the definition of the well-known metric regularity property by fixing one of the points involved in the definition. The first resulting property is called metric subregularity and has attracted a lot of attention during the last decades. O...

Tracking Monetary-Fiscal Interactions across Time and Space

The long-term fiscal outlook of most high-income countries is grim. Should independent central bankers be afraid of an unpleasant monetarist arithmetic, i.e., fiscal imbalances spilling over to monetary policy and jeopardizing price stability? To provide some insights, this paper tracks the ...

On forbidden induced subgraphs for K(1,3)-free perfect graphs

We study {K(1,3),Y}-free graphs, and show that the following three statements are equivalent: (1) every connected {K(1,3),Y}-free graph which is distinct from an odd cycle and which has independence number at least 3 is perfect; (2) every connected {K(1,3),Y}-free graph which is distinc...

Elastic Thickness Determination from on-orbit GOCE Data and CRUST1.0

Elastic thickness (Te) is a parameter representing the lithospheric strength with respect to the loading. Those places, having large values of elastic thickness, flexes less. In this paper, the on-orbit measured gravitational gradients of the Gravity field and steady-state Ocean Circulation ...

Lithosperic elastic thickness estimates in central Eurasia

We estimate the elastic thickness of a continental lithosphere by using two approaches that combine the Vening Meinesz-Moritz (VMM) regional isostatic principle with isostatic flexure models formulated based on solving flexural differential equations for a thin elastic shell with and without ...

Regular dessigns uniquelly determined by a nilpotent automorphism group

In this paper we consider the classification of uniquelly regular Grothendick dessins with nilpotent automorphism groups. The problem is reduced to the classification of finite maximally automorphic p-groups.

On Arbitrarily Long Periodic Orbits of Evolutionary Games on Graphs

A periodic behavior is a well observed phenomena in biological and economical systems. We show that evolutionary games on graphs with imitation dynamics can display periodic behavior for an arbitrary choice of game theoretical parameters describing social-dilemma games. We construct graphs a...

On sign-changing solutions for (p, q)-Laplace equations with two parameters

We investigate the existence of nodal (sign-changing) solutions to the Dirichlet problem for a two-parametric family of partially homogeneous (p, q)-Laplace equations −Δpu − Δqu = α|u|p−2u + β|u|q−2u where p ≠ q. By virtue of the Nehari manifolds, the linking theorem, and descendi...

Well-posedness and maximum principles for lattice reaction-diffusion equations

Existence, uniqueness and continuous dependence results together with maximum principles represent key tools in the analysis of lattice reaction-diffusion equations. In this paper, we study these questions in full generality by considering nonautonomous reaction functions, possibly nonsymmetric diffusion a...

Airway dimension and orthodontic treatment of distoocclusion

The presented study evaluates the ways in which an extraction or non-extraction orthodontic treatment of distoocclusion in growing patients may affect selected skeletal and dental parameters and anteroposterior dimension of airways in the area of oropharynx as represented in the cephalogram, ...

Convergence to travelling waves in Fisher’s population genetics model with a non-Lipschitzian reaction term

We consider the Fisher equation for advance of advatageous gene with non-Lipschitzian reaction term. We prove new travelling wave profiles and the convergence of the Cauchy problem to one of those profiles.

Forced duffing equation with a non-strictly monotonic potential

This article is devoted to study the existence of a solution to the periodic nonlinear second order ordinary differential equation with damping u''(x)+ c u'(x)+g(x,u)=f(x) x in [0,T] , u(0)=u(T), u'(0)=u'(T), where c in R, g is a Carath'eodory function, f in L^1(...
