Bifurcation of positive solutions for a semilinear equation with critical Sobolev exponent

Electronic Journal of Differential Equations, 2006
In this note we consider bifurcation of positive solutions to the semilinear elliptic boundary-value problem with critical Sobolev exponent $$displaylines{ -Delta u = lambda u - alpha u^p+ u^{2^*-1}, quad u >0 , quad hbox{in } Omega,cr u=0, quad hbox ...

PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

Molecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

An existence result for $(p,q)$-Laplacian BVP with falling zeros.

Electronic Journal of Qualitative Theory of Differential Equations
We show the existence of a positive solution to the $(p,q)$-Laplacian problem \begin{equation*} \begin{cases} -\Delta _{p}u-a\Delta _{q}u=\lambda f(u)-h(x)\quad \text{in }\Omega, \\ u=0\quad \text{on }\partial \Omega, \end{cases} \end{equation*} for ...

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

Molecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Global bifurcation of positive solutions for a superlinear $p$-Laplacian system

Electronic Journal of Qualitative Theory of Differential Equations
We are concerned with the principal eigenvalue of \begin{equation*} \begin{cases} -\Delta_p u= \lambda\theta_1\varphi_p(v), &x\in \Omega,\\ -\Delta_p v= \lambda\theta_2\varphi_p(u), &x\in \Omega,\\ u=0=v,\ &x\in\partial\Omega \

Positive Solutions of an Emden-Fowler Equation

Journal of Mathematical Analysis and Applications, 1994
Some new results concerning asymptotic integration and global existence of positive solutions of the Emden-Fowler equation \((r(t)x')' = P(t) | x |^{\nu-1} x\) are given. These results improve well known results of this area. Some applications to certain elliptic problems are given, too.

Inhibition of CDK9 enhances AML cell death induced by combined venetoclax and azacitidine

Molecular Oncology, EarlyView.
The CDK9 inhibitor AZD4573 downregulates c‐MYC and MCL‐1 to induce death of cytarabine (AraC)‐resistant AML cells. This enhances VEN + AZA‐induced cell death significantly more than any combination of two of the three drugs in AraC‐resistant AML cells.

Positive solutions for concave-convex type problems for the one-dimensional $\phi$-Laplacian

Electronic Journal of Qualitative Theory of Differential Equations
Let $\Omega=(a,b)\subset\mathbb{R}$, $0\leq m,n\in L^{1}(\Omega)$, $\lambda,\mu>0$ be real parameters, and $\phi: \mathbb{R}\rightarrow\mathbb{R}$ be an odd increasing homeomorphism.
