Compression‐Induced Amorphization of ZIF‐62 Leading to Formation of Porous Glass: Overcoming the Limitations of Current Methods

Chemistry–Methods, EarlyView.
Nonhydrostatic compression in steps is applied to transform crystalline zeolitic imidazolate framework‐62 into glass at room temperature. This method overcomes the limitations of existing approaches. This research reveals the mechanism of this phase transformation, including modifications in porosity, using various techniques, particularly positron ...

Application of Digital Anti-Coincidence Counting Method for Primary Activity Determination of 59Fe

Atom Indonesia, 2019
As a radiopharmaceutical, the use of 59Fe is classified as a high pharmaceutical risk product. Therefore, a standard reference for activity measurement of 59Fe is necessary to ensure its metrological aspect. This paper describes an alternative method for

Advances in Kinetic Isotope Effect Measurement Techniques for Enzyme Mechanism Study

Molecules, 2013
Kinetic isotope effects (KIEs) are a very powerful tool for investigating enzyme mechanisms. Precision of measurement is the most important factor for KIE determinations, especially for small heavy atom KIEs.

Biological evaluation of a glucose‐based boron carrier as a potential agent for boron neutron capture therapy

International Journal of Cancer, EarlyView.
What's New? Boron neutron capture therapy (BNCT) is a targeted form of radiation therapy designed to selectively destroy cancer cells. BNCT is not widely used, however, owing in part to challenges involving selective boron delivery to tumors. The present study evaluated the potential of a novel glucoconjugate, 6‐O‐(o‐carboranylmethyl)‐d‐glucopyranose ...

Estrogen and Progesterone Exhibit Distinct Yet Coordinated Roles in the Regulation of Tendon Extracellular Matrix Remodeling

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Remodeling of the extracellular matrix (ECM) is required for the proper healing, strengthening, and maintenance of tendon tissue. There are well‐documented sex differences in tendon injury rates and healing outcomes, often attributed to either innate differences in tissue structure and resident cell signaling or the influence of sex hormones ...
