NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

On the $U_p$ operator in characteristic $p$ [PDF]

open access: yesMathematical Research Letters, 2014
For a perfect field κof characteristic p>0, a positive ingeger N not divisible by p, and an arbitrary subgroup Γof GL_2(Z/NZ), we prove (with mild additional hypotheses when p\le 3) that the U-operator on the space M_k(Γ/κ) of (Katz) modular forms for Γover κinduces a surjection U:M_{k}(Γ/κ)\rightarrow M_{k'}(Γ/κ) for all k\ge p+2, where k'=(k-k_0 ...
