[The use of TruCare III insulin pump in patients with type 1 diabetes mellitus].

The development of devices for continuous subcutaneous insulin infusion (CSII or insulin pumps) dramatically improved medical care for patients with diabetes mellitus. Insulin pump production widens annually resulting in number of new models entering the market, that differs in price but are similar in technical features. The entering of such new models to the Russian market can cause practical issues both in patient and in health care provider, so their estimation is of great importance.

SHANK3 depletion leads to ERK signalling overdose and cell death in KRAS-mutant cancers.

The KRAS oncogene drives many common and highly fatal malignancies. These include pancreatic, lung, and colorectal cancer, where various activating KRAS mutations have made the development of KRAS inhibitors difficult. Here we identify the scaffold protein SH3 and multiple ankyrin repeat domain 3 (SHANK3) as a RAS interactor that binds active KRAS, including mutant forms, competes with RAF and limits oncogenic KRAS downstream signalling, maintaining mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) activity at an optimal level.

Cellular stiffness sensing through talin 1 in tissue mechanical homeostasis.

Tissue mechanical properties are determined mainly by the extracellular matrix (ECM) and actively maintained by resident cells. Despite its broad importance to biology and medicine, tissue mechanical homeostasis remains poorly understood. To explore cell-mediated control of tissue stiffness, we developed mutations in the mechanosensitive protein talin 1 to alter cellular sensing of ECM.

Regulation of the DLC3 tumor suppressor by a novel phosphoswitch.

Deleted in liver cancer 3 (DLC3) is a Rho GTPase-activating protein (RhoGAP) that plays a crucial role in maintaining adherens junction integrity and coordinating polarized vesicle transport by modulating Rho activity at the plasma membrane and endomembranes. By employing bioinformatical sequence analysis, experiments, and assays we here identified a polybasic region (PBR) in DLC3 that facilitates the association of the protein with cellular membranes. Within the PBR, we mapped two serines whose phosphorylation can alter the electrostatic character of the region.

Spin Inertia and Auto-Oscillations in Ferromagnets.

Recent experimental confirmation of spin inertia in ferromagnets positions this well-developed material class as a prime candidate for THz frequency applications. Spin-torque driven critical spin dynamics, such as auto-oscillations, play the central role in many spin-based technologies. Yet, the pressing question on spin inertia's effect on spin-torque driven dynamics in ferromagnets has remained unexplored.
