Sentinel lymph nodes biopsy for malignant tumors using Technefit radioactive colloid Technetium Tc.

Technetium-99m (99mTc) is a short-lived nanocolloid nuclide widely used by oncologists to diagnose and identify cancer dissemination.

Changes in Functional Activity of Platelets under the Influence of Submicron Particles Based on Mesoporous Silica and pH-Sensitive Polymers.

In vitro and in vivo effects of mesoporous silica nanoparticles (MSN) on the functional activity of platelets were studied in experiments on white rats. MSN particles, neither uncoated nor coated with calcium alginate, induced spontaneous platelet aggregation when added to platelet-rich plasma, but significantly enhanced ADP-induced platelet aggregation. Subcutaneous administration of uncoated and calcium alginate-coated MSN resulted in increased maximum size and rate of platelet aggregate formation 1 day post-injection.

Beneficial and Safety Properties of a Bacteriocinogenic and Putative Probiotic subsp. 2a Strain.

This work aimed to evaluate some of the probiotic features and safety of the bacteriocin-producing subsp. 2a. The effect of selected commercial drugs from different generic groups and antibiotics on the growth of subsp.

Io's tidal response precludes a shallow magma ocean.

Io experiences tidal deformation due to its eccentric orbit around Jupiter, which provides a primary energy source for Io's ongoing volcanic activity and infrared emission. The amount of tidal energy dissipated within Io is enormous and has been hypothesized to support the large-scale melting of Io's interior and the formation of a global subsurface magma ocean. If Io has a shallow global magma ocean, its tidal deformation would be much larger than in the case of a more rigid, mostly solid interior.
