Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS 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.

Chiellini Hamiltonian Lienard differential systems

open access: yesElectronic Journal of Differential Equations, 2019
We characterize the centers of the Chiellini Hamiltonian Lienard second-order differential equations $x'=y$, $y'=-f(x) y -g(x)$ where $g(x)=f(x) (k - \alpha (1 +\alpha) \int f(x) dx )$ with $\alpha, k \in \mathbb{R}$.

open access: yesJurnal Bimbingan dan Konseling Terapan, 2019
The application of learning and the use of the proper learning model really need to be considered in order to help find out students' understanding of what is conveyed by the teacher. Problem Based Learning is a learning model that focuses on students or

On the center-focus problem for the equation $\frac{dy}{dx} + \sum_{i=1}^n a_i(x) y^i = 0, 0\leq x \leq 1$ where $a_i$ are polynomials [PDF]

open access: yesAnnales Henri Lebesgue, 2020
We study irreducible components of the set of polynomial plane differential systems with a center, which can be seen as a modern formulation of the classical center-focus problem. The emphasis is given on the interrelation between the geometry of the center set and the Picard–lefschetz theory of the bifurcation (or Poincaré–Pontryagin–Melnikov ...

Effect of aspect ratio on transverse diffusive broadening: A lattice Boltzmann study

open access: yes, 2009
We study scaling laws characterizing the inter-diffusive zone between two miscible fluids flowing side by side in a Y-shape laminar micromixer using the lattice Boltzmann method.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

The radical of the focal values ideal of the complex Kukles system

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2018
In the article it is considered the center-focus problem for complex Kukles system x = y, y = -x + Ax2 + 3Bxy + Cy2 + Kx3 + 3Lx2y + Mxy2 + Ny3. The problem is solved by the new method, obtained by A. P.

Monodromy problem and Tangential center-focus problem for product of generic lines in $\mathbb{P}^2$

open access: yes, 2022
We consider the rational map $F$ defined by the quotient of products of lines in general position and we study the monodromy problem and tangential center-focus problem for the fibration associated with $F$. Thus, we study the submodule of the 1-homology group of a regular fiber of $F$ generated by the orbit of the monodromy action on a vanishing cycle.

Do we understand the incompressibility of neutron-rich matter?

open access: yes, 2009
The ``breathing mode'' of neutron-rich nuclei is our window into the incompressibility of neutron-rich matter. After much confusion on the interpretation of the experimental data, consistency was finally reached between different models that predicted ...

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

open access: yesMolecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.
