Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Synthesis of Aminocyclopropanes by Redox‐Neutral Aminoalkylation

Angewandte Chemie International Edition, EarlyView.
Aminocyclopropane synthesis by hydroaminoalkylation utilizing cheap, readily available starting materials is presented, offering orthogonality to commonly used methods and allowing broad functional‐group tolerance. Solvent‐mediated conditions enable the reaction of a pre‐formed hemiaminal with alkenes and alkynes.

Cis‐Vaccenic Acid as a Compositional Marker for Detecting High‐Oleic Seed Oil Adulteration in Avocado Oil

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The rapid expansion of the global avocado oil market has intensified concerns about economic adulteration with lower‐cost, high‐oleic seed oils that resemble the fatty acid specifications of avocado oil. Cis‐vaccenic acid C18:1 (n−7) occurs at higher proportions in avocado oil than in common seed oil adulterants, making it a promising ...

Nerve Growth Factor is Sufficient to Cause Multiple Osteoarthritis‐Relevant Pathologic Features in Naïve Murine Knee Joints

Arthritis &Rheumatology, EarlyView.
Objective Nerve growth factor (NGF), a key mediator of pain, is increased in osteoarthritic (OA) joints. Antibodies against NGF show analgesic effects in painful knee OA, but clinical development was stopped because of side effects in the joints. Knowledge about the biologic effects of NGF on joint tissues is limited. Therefore, we explored the effects

APPRAISAL OF DIAMONDS AND GEMSTONES : How to facilitate the separation of natural and synthetic gemstones

, 2018
One major problem in the gemstone industry is that it is difficult to determine whether if a gemstone is natural or synthetic. Natural gemstones are found in the interior of the earth while the synthetic gems are created by people.
