An in-house library of 335 antiviral natural products was prepared from the selected medicinal plants. Following the virtual screening of this library against the main protease and spike glycoprotein, top compounds were subjected to downstream analysis for evaluating druggability potential and toxicity analysis.

Amidst this crisis, antimicrobial peptides (AMPs) have emerged as promising alternatives to conventional antibiotics (ATBs). These cationic peptides, naturally produced by all kingdoms of life, play a crucial role in the innate immune system of multicellular organisms and in bacterial interspecies competition by exhibiting broad-spectrum activity against bacteria, fungi, viruses, and parasites.

VSA is commonly managed with antispasmodic medications including calcium-channel blockers and nitrates. When vasospasm is refractory to conventional medications, unconventional treatment modalities may be used for symptomatic relief.

The risk of coronary artery perforation is more significant during complex procedures as chronic total occlusions but it can occur in other circumstances such as oversized stents and/or balloons, excessive post-dilatation, and the use of hydrophilic wires. Coronary artery perforation is often not recognized during the procedure and the diagnosis is frequently not made until later when the patient develops signs related to pericardial effusion.

Unlabelled: Subaortic stenosis (SubAS) is a common cause of left ventricular outflow tract obstruction. It may be focal or diffuse, leading to the development of a subaortic tunnel. Considered for a long time as a congenital anomaly, SubAS has been established lately as an acquired anomaly and secondary to a pre-existing anatomic alteration in the interventricular septum and mitral valve apparatus.

We report a wide variety of ROP-initiating systems along with their detailed mechanisms. We focus on the challenges of preparing the polymers; the precise control of the properties of the materials, including molecular weight; the compositions of the copolymers and their structural characteristics.

Ninety-six olive oil samples have been harvested at different dates and from two seasons, processed using different extraction methods, collected from different altitudes and other factors that can increase the variability of the samples' chemical composition. Fluorescence excitation-emission matrices (EEM) of the collected samples were measured, and the relationship between them and the chemical parameters was examined.

A new concept is presented, namely the synthesis of dendrimers intrinsically composed in alternation of building blocks pertaining to two known families of dendrimers: phosphorhydrazone dendrimers and triazine-piperazine dendrimers. These mixed dendrimers with layered controlled architecture inherit their easy (31) P NMR characterization and their thermal stability from the phosphorhydrazone family, and their decreased solubility from the triazine-piperazine family. However, they have also their own and original characteristics.
