Positive and nodal solutions for nonlinear nonhomogeneous parametric Neumann problems
Electronic Journal of Differential Equations, 2020 We consider a parametric Neumann problem driven by a nonlinear nonhomogeneous differential operator plus an indefinite potential term. The reaction term is superlinear but does not satisfy the Ambrosetti-Rabinowitz condition.

FEBS Letters, EarlyView.Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

A critical point theorem and existence of multiple solutions for a nonlinear elliptic problem
Electronic Journal of Differential Equations, 2015 In this article, we show the existence of multiple nontrivial solutions to a Dirichlet problem for the p-Laplacian. Our approach is based on a abstract critical point theorem.

Endothelin receptor antagonist improves donor lung function in an ex vivo perfusion system
Journal of Biomedical Science, 2020 Background A lung transplant is the last resort treatment for many patients with advanced lung disease. The majority of donated lungs come from donors following brain death (BD). The endothelin axis is upregulated in the blood and lung of the donor after

British medical journal, 2010 Overwhelming evidence shows the quality of reporting of randomised controlled trials (RCTs) is not optimal. Without transparent reporting, readers cannot judge the reliability and validity of trial findings nor extract information for systematic reviews.

Journal of Algebra, 1980 Knowledge of properties and of the structure of so-called f-cr i t ical groups for a given class f of groups can often help to get detailed information for the structure of those groups, which belong to f . I f f is a class of groups, we say that a group G is f-cri t ical , if G ¢ f , but H ~ f for all proper subgroups H o f G.

Density-Matrix Renormalization-Group Analysis of Quantum Critical Points: I. Quantum Spin Chains
, 2000 We present a simple method, combining the density-matrix renormalization-group (DMRG) algorithm with finite-size scaling, which permits the study of critical behavior in quantum spin chains.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
