The Yin and Yang of Inflammation controlled by a Molecule

Dichotomous engagement of HDAC3 activity governs inflammatory ...
: Dichotomous functions of HDAC3 orchestrate the inflammatory response to endotoxin in vivo.

Researchers from the Perelman School of Medicine at the University of Pennsylvania have now identified a protein called histone deacetylase 3 (HDAC3) as the orchestrator of the immune system’s inflammation response to infection. By using both specially cultured cells and small animal models, HDAC3 was found to be directly involved in the production of agents that help kill off harmful pathogens as well as the restoration of homeostasis, the body’s state of equilibrium. This work, published in Nature, shows that some of the methods being tested to fight cancer and harmful inflammation, such as sepsis, that target molecules like HDAC3 could actually have unintended and deadly consequences.

Electric Cooker an easy, efficient way to Sanitize N95 Masks, study finds

One 50-minute, 212 F cooking cycle in a dry electric multicooker decontaminates an N95 respirator without chemicals and without compromising the filtration or fit.

Owners of electric multicookers may be able to add another use to its list of functions, a new study suggests: sanitization of N95 respirator masks.

The University of Illinois, Urbana-Champaign study found that 50 minutes of dry heat in an electric cooker, such as a rice cooker or Instant Pot, decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of the respirators, originally intended to be one-time-use items.

Led by civil and environmental engineering professors Thanh “Helen” Nguyen and Vishal Verma, the...

Scientists develop a new way to Deliver Drugs through the Skin

Scientists develop new way to deliver more drugs through the skin

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the Agency for Science, Technology and Research (A*STAR) have shown that applying ‘temporal pressure’ to the skin of mice can create a new way to deliver drugs.

In a paper published in Science Advances, the researchers showed that bringing together two magnets so that they pinch and apply pressure to a fold of skin, led to short term changes in the skin barrier and specifically the formation of “micropores” underneath its surface.

In tests, they showed t...

New molecule Reverses Alzheimer’s-like Memory Decline – The drug CMS121 treats neurodegeneration in mice

CMS121, a fisetin-derivative, alleviates memory decline in a double transgenic AD mouse model.

A drug candidate developed by Salk researchers, and previously shown to slow aging in brain cells, successfully reversed memory loss in a mouse model of inherited Alzheimer’s disease. The new research, published online in July 2020 in the journal Redox Biology, also revealed that the drug, CMS121, works by changing how brain cells metabolize fatty molecules known as lipids.

“This was a more rigorous test of how well this compound would work in a therapeutic setting than our previous studies on it,” says Pamela Maher, a senior staff scientist in the lab of Salk Professor David Schubert and the senior author of the new paper...
