Complicated infective endocarditis of the bioprosthetic mitral valve following the transcatheter mitral valve-in-valve procedure: a case report and literature review.

Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.

One-pot reaction of 3-vinylchromones, aromatic aldehydes, and ammonium acetate: an efficient approach to highly functionalized 1,6-dihydropyridine derivatives.

In this work, we present an efficient strategy for the straightforward synthesis of functionalized 1,6-dihydropyridine derivatives a three-component reaction of 3-vinylchromones, aromatic aldehydes, and ammonium acetate. A tandem procedure including NH aldimine formation/Michael-type addition/opening of the pyrone ring/isomerization/6π-electrocyclization/[1,5]-H shift allows rapid access to a series of dihydropyridines bearing an -hydroxybenzoyl and a benzoyl scaffold in good yields. Readily available precursors, simple heating conditions, and operational simplicity are some highlighted advantages of this transformation.

Nose-to-Brain Targeting of Resveratrol Nanoformulations.

Resveratrol [RES] is a polyphenolic stilbene with therapeutic potential owing to its antioxidant, anti-inflammatory, neuroprotective, and cardioprotective properties. However, the very poor oral bioavailability, fast metabolism, and extremely low stability under physiological conditions pose a severe detriment to the clinical use of RES. This newly developed field of nanotechnology has led to the formulation of RES into nanoformulations with the goal of overcoming metabolicpharmacokinetic limitations and enhancing the targeted transport of RES to the central nervous system [CNS].

Metformin and Cognitive Performance in Patients With Type 2 Diabetes: An Umbrella Review.

Contradictory results for the association between metformin intake and changes in cognitive function have been reported. We attempted to overview systematic reviews and meta-analyses showing the role of metformin, as mono or combination therapy, in cognitive performance alterations among patients with type 2 diabetes mellitus (T2DM) and to determine the quality of the evidence as well.

A state-of-the-art review of the recent advances of theranostic liposome hybrid nanoparticles in cancer treatment and diagnosis.

Theranostics is a way of treating illness that blends medicine with testing. Specific characteristics should be present in the best theranostic agents for cancer: (1) the drugs should be safe and non-toxic; (2) they should be able to treat cancer selectively; and (3) they should be able to build up only in the cancerous tissue. Liposomes (LPs) are one of the most efficient drug delivery methods based on nanotechnology.
