Positive solutions of the diophantine equation
International Journal of Mathematics and Mathematical Sciences, 1981 Integral solutions of x3 + λy + 1 − xyz = 0 are observed for all integral λ. For λ = 2 the 13 solutions of the equation in positive integers are determined. Solutions of the equation in positive integers were previously determined for the case λ = 1.

Positive solutions of elliptic nonpositone problems
Differential and Integral Equations, 1992 The authors give conditions for the existence or nonexistence of positive solutions of second order subcritical elliptic nonpositone problems. No assumption is made that the problems be radial nor that they possess a variational structure.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Even number of positive solutions for 3nth order three-point boundary value problem on time scales
Electronic Journal of Qualitative Theory of Differential Equations, 2011 We establish the existence of at least two positive solutions for the 3nth order three-point boundary value problem on time scales by using Avery-Henderson fixed point theorem.

FEBS Letters, EarlyView.Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Electronic Journal of Qualitative Theory of Differential Equations, 2016 We study a variational property on the evolutionary bifurcation curves for the one-dimensional perturbed Gelfand problem from combustion theory \begin{equation*} \begin{cases} u^{\prime \prime }(x)+\lambda \exp \left( \frac{au}{a+u}\right) =0, & -10$ is ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Asymptotically linear and superlinear elliptic equations with gradient terms
Electronic Journal of Differential Equations, 2020 In this article we establish the existence of solutions for elliptic problem involving a gradient term. To handle the so-called non-variational problem, we use a variational methods. We assume that the nonlinear term satisfies an asymptotically linear

Existence and iteration of a positive solution to a second‐order quasilinear problem
Mathematical Modelling and Analysis, 2010 A successive iteration sequence of positive solution is structured for a singular second‐order quasilinear problem. The sequence can converge uniformly to the positive solution of the problem.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
