Here are the quickie reports about cutting edge medical and healthcare discoveries this 3rd week of July, 2022.
With more and more challenging CoVid subvariants arriving on the scene, infectious disease research collaborators led by those at the University of Virginia are looking to boosters in nasal sprays to offer greater protection. The sprays will deliver inactivated forms of the virus itself to nasal and upper respiratory linings where the greater numbers of CoVid antigens in whole viruses compared with the number encoded by mRNA vaccines will trigger a vigorous immune response that both prevents infections and limits viral spread to others.

Crying at your doctor’s office may help diagnose eye ailments. Chinese researchers report the use of what they have dubbed the iTEARS nanomembrane system to extract tiny cellular capsules called exosomes that contain molecular clues about the state of cellular wellness or disease in eye tissues. This technique may also permit the use of tears for diagnosis of neurodegenerative diseases and cancers.

A tablespoon of blood from a patient with metastatic cancer may soon help that patient’s oncology team tailor the best therapy to control and possibly eradicate that cancer. Researchers at the University of British Columbia have developed techniques for evaluating circulating tumor DNA in order to characterize the various populations of residual cancers cells requiring further treatment with a custom combination of chemotherapy, immunotherapy, and gene therapy.

Your spit may help protect you from CoVid. Japanese investigators have demonstrated that saliva from healthy individuals inhibits the binding of CoVid spike proteins to the ACE2 binding sites on human cells. Their analysis shows that 2 salivary proteins, the positively charged neutrophil elastase and histone H2A, prevent binding to the negatively chanred ACE2 site. This finding may be a good reason to emphasize mouthbreathing when you are out and about.
