| Synthetic hinge could hold key to revolutionary 'smart' insulin therapy Posted: 02 Aug 2021 01:06 PM PDT For people with diabetes who are insulin dependent, glycemic control is a full-time job. But what if their medication could do the work for them -- an insulin whose activity in the bloodstream responds to the blood glucose levels and adjusts accordingly? A new invention could lead to just that. |
| Posted: 02 Aug 2021 01:06 PM PDT When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. Researchers observed such offsets in both eyes of 20 healthy subjects, and speculate that the underlying fixation behavior improves overall vision. |
| Posted: 02 Aug 2021 01:06 PM PDT A new treatment for advanced urothelial cancer was effective with tolerable side effects in an international, multi-center phase 2 clinical trial. The trial results prompted a U.S. Food and Drug Administration (FDA) accelerated approval of the treatment on April 13, giving patients with this very aggressive type of cancer a new therapeutic option. |
| Scientists boost gene knockdown in human cells via chemically modified RNA CRISPR Posted: 02 Aug 2021 11:01 AM PDT In the latest of ongoing efforts to expand technologies for modifying genes and their expression, researchers have developed chemically modified guide RNAs for a CRISPR system that targets RNA instead of DNA. These chemically-modified guide RNAs significantly enhance the ability to target -- trace, edit, and/or knockdown -- RNA in human cells. |
| Natural mineral hackmanite enables new method of x-ray imaging Posted: 02 Aug 2021 11:01 AM PDT Researchers have discovered a new method of X-ray imaging based on the coloring abilities of the natural mineral hackmanite. The international group of researchers also found out how and why hackmanite changes color upon exposure to X-rays. |
| Molecular switch regulates fat burning in mice Posted: 02 Aug 2021 11:01 AM PDT New research demonstrates a metabolic regulatory molecule called Them1 prevents fat burning in cells by blocking access to their fuel source. The study may contribute to the development of a new type of obesity treatment. |
| Cutting 250 calories daily and exercising may improve heart health in obese older adults Posted: 02 Aug 2021 11:01 AM PDT Among older adults with obesity, combining aerobic exercise with moderate reductions in total daily calories led to greater improvements in vascular health compared to exercise alone. Reducing calorie intake by approximately 250 calories per day may lead to significant weight loss and improve vascular health in older adults with obesity. |
| Drug-resistant germ packs punch to US travelers Posted: 02 Aug 2021 11:01 AM PDT One type of the salmonella bacteria is much more likely to cause disease and fend off frontline antibiotics when acquired in Europe, Asia, and parts of Africa rather than domestically in the United States. |
| Internet CBT for depression reviewed and analyzed Posted: 02 Aug 2021 08:50 AM PDT Internet-based cognitive behavioral therapy (CBT) for depression is often just as effective as traditional CBT. This is clear from an international study. However, some online treatments have components that can potentially be harmful. |
| Atomic-level, 3-D structure of MUTYH protein opens small window into DNA repair mechanism Posted: 02 Aug 2021 08:49 AM PDT A research team has analyzed the three-dimensional structure of a protein that suppresses the development of colorectal polyposis, MUTYH, at the atomic level and clarified the repair mechanism for DNA mispairings. Since mutations in the MUTYH gene cause heritable colorectal polyposis, which leads to colorectal cancer, the researchers expect that this work will be useful for future research on heritable colorectal polyposis associated with MUTYH. |
| Host proteins that impair Ebola virus infection identified Posted: 02 Aug 2021 07:30 AM PDT Several proteins have been identified in hosts that interact with Ebola virus and primarily function to inhibit the production of viral genetic material in cells and prevent Ebola virus infection, according to a new study. |
