A plasma patch could soon be used to dress wounds. Plasma is a state of matter, like a solid or gas, and can kill bacteria including those that are resistant to antibiotics. Normally plasmas form at high temperatures, but a new patch can create cold plasmas that may be ideal for use on the body.

The patch is developed by German company Coldplasmatech and produces a plasma by sending high energy electrons through the air between the patch and skin. This rips some of the electrons off molecules …

New research on brain ageing and mitochondria from Salk Institute.

Thanks to a new technique, researchers from the Salk Institute’s Gage laboratory have shown that impaired energy production might be a reason why human brains are susceptible to age-related diseases in the first place [1].

In particular, Salk scientists observed that induced neurons (iNs) obtained from fibroblasts of older individuals had dysfunctional mitochondria and therefore decreased energy levels compared to younger neurons. Out-of-shape mitochondria have previously been implicated in degenerative brain diseases, such as Alzheimer’s and Parkinson’s, and this finding might help reveal more about the connection between these diseases and this particular hallmark of aging.

Newts are the only four-legged vertebrates that can regenerate their body parts, even as adults. When a newt loses a limb, a mass of cells called a blastema is generated at the stump, from which a new, fully functional limb is eventually regenerated. Can this remarkable ability be explained by genes shared by vertebrates, including humans, or by unique genes that the newt may have evolved?

In a study published in Scientific Reports, researchers at several Japanese universities, including the University of Tsukuba, and the University of Dayton, report the discovery of a novel gene, Newtic1, from the blastema of an adult newt. This gene is expressed in a subset of red blood cells and may contribute to limb regeneration in adult newts. Red blood cells, or erythrocytes, function to deliver oxygen around an animal’s body. Unlike the other cells in the mammalian body, the erythrocytes lack nuclei, allowing them to carry more oxygen and squeeze into fine blood vessels. In the newt and most other non-mammalian species, however, these cells contain a nucleus. Other than oxygen delivery, the function of these nucleated cells is unknown. This study provides, for the first time, an insight into the roles of these nucleated cells.

In the study, the researchers constructed a database of all the protein-coding genes from the Japanese fire-bellied newt that had been reported in the Japan newt research community. This database contained DNA sequence information of genes from 19 different tissues, including different regenerating organs and limb blastemas. To identify genes related to limb regeneration, they used statistical analyses to look for genes whose expression was increased in association with the formation of the limb blastema. From 694,138 sequences, they found 105,464 expressed in the limb blastema. Further screening of these sequences resulted in the identification of a single gene which was named Newtic1. Its existence in newt tissues was confirmed using both DNA- and protein-based methods. Similar genes exist in axolotl and another newt species, but not in any other species.

A shortage of antibiotics is causing doctors to prescribe incorrect antibiotics for certain infections. That, in turn, is allowing antibiotic resistant organisms to develop defenses and some of those may no longer be treatable with antibiotics.

Kelsey-Seybold doctor Shane Magee says there are lots of drug shortages.

A recently published case study from an ongoing clinical trial has revealed an experimental immunotherapy treatment has cured a breast cancer patient. The 49-year-old patient with advanced breast cancer was given three months to live before enrolling into the trial. Within weeks her tumors had disappeared and 22 months later she is still in complete remission.

The treatment being trialed is a modified form of what is called adoptive immunotherapy. The technique generally works by harvesting a person’s immune cells. Once collected, the cells are armed with cancer-recognizing molecules so that when they are reintroduced into the patient’s body they can home in on the tumors and kill them off.

This form of immunotherapy has frustratingly been inconsistent in early clinical trials, working well with some patients on certain cancers but proving less effective on others. In particular, the treatment hasn’t been hugely successful in treating common epithelial cancers. These cancers tend to harbor lower levels of mutations that are fundamental to programming the immune cells to hit their targets.
