Cyclic peptides: A powerful instrument for advancing biomedical nanotechnologies and drug development.

Cyclic peptides have emerged as an essential tool in the advancement of biomedical nanotechnologies, offering unique structural and functional advantages over linear peptides. This review article aims to highlight the roles of cyclic peptides in the development of biomedical fields, with a particular focus on their application in drug discovery and delivery. Cyclic peptides exhibit exceptional stability, bioavailability, and binding specificity, making them ideal candidates for therapeutic and diagnostic applications.

High Magnetic Performance in MnGa Nanocomposite Magnets.

In view of their potential applicability in technology fields where magnets are required to operate at higher temperatures, the class of nanocomposite magnets with little or no rare earth (RE) content has been widely researched in the last two decades. Among these nanocomposite magnets, the subclass of magnetic binary systems exhibiting the formation of L1 tetragonal phases is the most illustrious. Some of the most interesting systems are represented by the Mn-based alloys, with addition of Al, Bi, Ga, Ge.

Magnetic Properties and THz Emission from Co/CoO/Pt and Ni/NiO/Pt Trilayers.

THz radiation emitted by ferromagnetic/non-magnetic bilayers is a new emergent field in ultra-fast spin physics phenomena with a lot of potential for technological applications in the terahertz (THz) region of the electromagnetic spectrum. The role of antiferromagnetic layers in the THz emission process is being heavily investigated at the moment. In this work, we fabricate trilayers in the form of Co/CoO/Pt and Ni/NiO/Pt with the aim of studying the magnetic properties and probing the role of very thin antiferromagnetic interlayers like NiO and CoO in transporting ultrafast spin current.

Remarkable Magnetic Properties in a MnGa Alloy Produced via Out-of-Equilibrium Method.

Rare-earth-free permanent magnets with the L1 phase are actively researched for their potential as a future class of magnetic materials, capable of operating at higher temperatures and in challenging corrosion environments such as renewable energy applications. Among these classes, MnGa shows potential, being cost effective and having interesting magnetic properties. A MnGa magnetic alloy, with composition MnGa in atomic percent, was produced via the out-of-equilibrium method, and its structural and magnetic properties were assessed using X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and extended magnetic characterization.

Therapeutic Plasma Exchange in Catastrophic Antiphospholipid Syndrome (CAPS): A Rare Case Report and Literature Review.

Background/aim: Catastrophic antiphospholipid syndrome (CAPS) may be the first manifestation ("de novo") of antiphospholipid syndrome (APS) or a complication in the clinical course of patients known to have this syndrome. Approximately 40% of patients had an associated autoimmune disease, mainly, systemic lupus erythematosus (SLE). The trigger can be one of the following: infections, surgical interventions, neoplasms, pregnancy, discontinuation of anticoagulant treatment, and others.
