95% of flu and herpes infection neutralized by chewing gum

Looking beyond jabs, sprays or tablets, scientists are thinking outside the box for delivering antiviral medication to prevent the spread of highly transmissible bugs. Their secret weapon? Chewing gum – but not any gum. This one is made from a rather fascinating bean.

Researchers from the University of Pennsylvania's Penn Dental Medicine have been working on this novel model of drug delivery, focusing on attacking viruses that like to hide out in our throats and nose. The team looked at neutralizing herpes simplex viruses (HSV-1 and HSV-2) and influenza A strains (H1N1 and H3N2) through a clinically loaded chewing gum made with lablab beans (Lablab purpureus).

This bean – also known as the hyacinth, Egyptian kidney, and Indian bean – is a legume that contains a protein that can "trap" and neutralize certain viruses, essentially giving it antiviral properties. This protein, FRIL, is also inherently stable when the legume is converted into a powder and turned into chewing gum.

Drug candidate successfully treats atherosclerosis and fatty liver disease in large mammals

by Noah Fromson, University of Michigan

A drug candidate, previously successful at treating severe fatty liver disease, reduces atherosclerosis—a primary driver of cardiovascular death worldwide—in large mammals, a study suggests.

DT-109 limited the formation of atherosclerotic plaques in both the aorta and coronary arteries of nonhuman primates. The amino acid compound was developed at the University of Michigan.

This glycine-based tripeptide also stopped critical processes that lead to vascular calcification, a significant catalyst of arterial stiffening and plaque instability.

Results of the study, conducted in partnership with Xi'an Jiaotong University Health Science Center, are published in Signal Transduction and Targeted Therapy.

Early embryos show surprising flexibility in fixing DNA organization mistakes

by Helmholtz Association of German Research Centres

An international research team led by Helmholtz Munich has, for the first time, provided a detailed insight into how the spatial organization of genetic material is established in the cell nucleus of early embryos within the first hours after fertilization. Surprisingly, embryos demonstrate a high degree of flexibility in responding to disruptions in this process.

The study, now published in Cell, reveals that no single master regulator controls this nuclear organization. Instead, multiple redundant mechanisms ensure a robust and adaptable nuclear architecture, allowing embryos to correct errors in the initial organization of their nucleus.
