Protective role of R-spondin1, an intestinal stem cell growth factor, against radiation-induced gastrointestinal syndrome in mice. [PDF]
BACKGROUND:Radiation-induced gastrointestinal syndrome (RIGS) results from a combination of direct cytocidal effects on intestinal crypt and endothelial cells and subsequent loss of the mucosal barrier, resulting in electrolyte imbalance, diarrhea ...

mazkur maqolada qalbimning rayhoni bo‘lgan insonga yetkizmoqchi bo‘lgan so‘zlarimni qisman bayon qilganman. Shu bilan birga men yoqtirgan insonga bu maqolada hech qachncha tarif berilmagan, agar tarifni to‘laqonli bilmoqchi bo‘lgan insonlar bo‘lsa marhamat qalbimga kirib bu isnsonga bo‘lgan sevgimni ko‘rib bilib olsin.

Chasmogamy and entomophily in Burmannia disticha (Burmanniaceae)
Burmannia shows a set of floral traits that suggest elaborate mechanisms of animal-mediated pollen transfer. These include flower coloration, septal nectaries and a long and narrow floral chamber.

A unification in the theory of linearization of second order nonlinear ordinary differential equations [PDF]
In this letter, we introduce a new generalized linearizing transformation (GLT) for second order nonlinear ordinary differential equations (SNODEs). The well known invertible point (IPT) and non-point transformations (NPT) can be derived as sub-cases of ...

Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

On approximating the nearest \Omega-stable matrix
In this paper, we consider the problem of approximating a given matrix with a matrix whose eigenvalues lie in some specific region \Omega, within the complex plane. More precisely, we consider three types of regions and their intersections: conic sectors,

Escape of mass and entropy for diagonal flows in real rank one situations
Let $G$ be a connected semisimple Lie group of real rank 1 with finite center, let $\Gamma$ be a non-uniform lattice in $G$ and $a$ any diagonalizable element in $G$. We investigate the relation between the metric entropy of $a$ acting on the homogeneous

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII
