HEX17(Neumifil): An intranasal respiratory biotherapeutic with broad-acting antiviral activity.

Broad-acting antiviral strategies to prevent respiratory tract infections are urgently required. Emerging or re-emerging viral diseases caused by new or genetic variants of viruses such as influenza viruses (IFVs), respiratory syncytial viruses (RSVs), human rhinoviruses (HRVs), parainfluenza viruses (PIVs) or coronaviruses (CoVs), pose a severe threat to human health, particularly in the very young or old, or in those with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). Although vaccines remain a key component in controlling and preventing viral infections, they are unable to provide broad-spectrum protection against recurring seasonal infections or newly emerging threats.

Blood flows from the SCN toward the OVLT within a new brain vascular portal pathway.

The suprachiasmatic nucleus (SCN) sets the phase of oscillation throughout the brain and body. Anatomical evidence reveals a portal system linking the SCN and the organum vasculosum of the lamina terminalis (OVLT), begging the question of the direction of blood flow and the nature of diffusible signals that flow in this specialized vasculature. Using a combination of anatomical and in vivo two-photon imaging approaches, we unequivocally show that blood flows unidirectionally from the SCN to the OVLT, that blood flow rate displays daily oscillations with a higher rate at night than in the day, and that circulating vasopressin can access portal vessels.

A Single-Short Partial Reprogramming of the Endothelial Cells decreases Blood Pressure via attenuation of EndMT in Hypertensive Mice.

Background: Small artery remodeling and endothelial dysfunction are hallmarks of hypertension. Growing evidence supports a likely causal association between cardiovascular diseases and the presence of endothelial-to-mesenchymal transition (EndMT), a cellular transdifferentiation process in which endothelial cells (ECs) partially lose their identity and acquire additional mesenchymal phenotypes. EC reprogramming represents an innovative strategy in regenerative medicine to prevent deleterious effects induced by cardiovascular diseases.
