AI tool could predict how drugs will react in the body

October 13th, 2020 at 9:21 am » Comments Off

  “The safety of a drug does not depend only on the drug itself but also on the metabolites that can be formed when the drug is processed in the body,” says Eleni Litsa A new deep learning-based tool called Metabolic Translator may soon give researchers a better handle on how drugs in development will […]

Breast milk could stop virus spreading, researchers claim

October 9th, 2020 at 11:35 am » Comments Off

  Whey proteins in cow and goat milk also could inhibit the virus but is less effective than human breast milk.   Human breast milk could help to prevent or treat COVID-19, according to a new study by Chinese scientists, lending support to World Health Organisation guidelines that mothers should breastfeed their newborn babies even […]

Experimental cancer treatment destroys cancer cells without using any drugs

October 7th, 2020 at 11:33 am » Comments Off

One of the latest methods pioneered by scientists to treat cancer uses a Trojan horse sneak attack to prompt cancer cells to self-destruct – all without using any drugs. Key to the technique is the use of a nanoparticle coated in a specific amino acid called L-phenylalanine, one of several such acids that cancer cells […]

How CRISPR is tackling the troubling immune response that’s plagued gene therapy until now

September 23rd, 2020 at 10:38 am » Comments Off

One of the major challenges facing gene therapy — a way to treat disease by replacing a patient’s defective genes with healthy ones — is that it is difficult to safely deliver therapeutic genes to patients without the immune system destroying the gene, and the vehicle carrying it, which can trigger life-threatening widespread inflammation. Three […]

To repair a damaged heart, three cells are better than one

September 19th, 2020 at 12:33 am » Comments Off

  Cell therapy for cardiac regeneration, while promising, has been hampered by issues with long-term survival of the transplanted cells. Now, a technique that combines three different types of cells in a 3-D cluster could improve its efficacy in reducing scar tissue and improving cardiac function after a heart attack. Called CardioCluster, the bioengineering technique […]

Cryogenic 3Dprinting improves bioprinting for bone regeneration

September 18th, 2020 at 12:23 am » Comments Off

  Researchers from China continue in the quest to improve methods for bone regeneration, publishing their findings in “Cryogenic 3D printing of dual-delivery scaffolds for improved bone regeneration with enhanced vascularization.” A wide range of projects have emerged regarding new techniques for bone regeneration—especially in the last five years as 3D printing has become more […]

Robot skin 3D printer close to first-in-human clinical trials

September 4th, 2020 at 11:21 am » Comments Off

In just two years a robotic device that prints a patient’s own skin cells directly onto a burn or wound could have its first-in-human clinical trials. The 3D bioprinting system for intraoperative skin regeneration developed by Australian biotech start-up Inventia Life Science has gained new momentum thanks to major investments from the Australian government and […]

Rejuvenating old organs could increase donor pool

September 3rd, 2020 at 11:07 am » Comments Off

Despite the limited supply of organs available for patients on waitlists for transplantation, organs from older, deceased donors are frequently discarded or not utilized. Available older organs have the potential to close the gap between demand and supply that is responsible for the very long wait-times that lead to many patients not surviving the time […]

World-first database catalogs 1,000s of viruses in our gut microbiome

August 31st, 2020 at 3:01 pm » Comments Off

  A new study detected over 33,000 unique virus populations that reside in human gut microbiomes Researchers from Ohio State University have created the first catalog of viral populations known to inhabit the human gut. Called the Gut Virome Database, the study suggests each person’s gut viral population is as unique as their fingerprints. Our […]

Cashew shell compound appears to mend damaged nerves

August 30th, 2020 at 1:18 pm » Comments Off

Summary: Anacardic acid, a compound found in cashew shells, promotes the repair of myelin. The findings could have positive implications for the treatment of diseases, such as multiple sclerosis, that are characterized by demyelination. Source: Vanderbilt University Medical Center In laboratory experiments, a chemical compound found in the shell of the cashew nut promotes the […]

Why do Covid fatalities remain low when infection numbers are rising?

August 28th, 2020 at 3:17 pm » Comments Off

  While some scientists believe the virus has become less deadly, others look at the factors that suggest otherwise Are Covid-19 death rates decreasing? Most statistics indicate that although cases of Covid-19 are rising in many parts of Europe and the United States, the number of deaths and cases of severe complications remain relatively low. […]

Unraveling the initial molecular events of respiration

August 23rd, 2020 at 10:38 am » Comments Off

  Respiration is a fundamental process of all living things, allowing them to produce energy, stay healthy, and survive. In cells, respiration involves what are known as “respiratory proteins,” e.g. hemoglobin in the blood and myoglobin in muscles. Respiratory proteins work by binding and releasing small molecules like oxygen, carbon monoxide etc., called ligands. They […]
