Synthetic extracellular matrices with tailored adhesiveness and degradability support lumen formation during angiogenic sprouting

Posted by in categories: bioengineering, biotech/medical

Current tissue engineering strategies lack materials that promote angiogenesis. Here the authors develop a microfluidic in vitro model in which chemokine-guided endothelial cell sprouting into a tunable hydrogel is followed by the formation of perfusable lumens to determine the material properties that regulate angiogenesis.

88 patients, 0 intubated: Israeli ‘precision’ COVID drug wrapping up early trial

Posted by in category: biotech/medical

The Israeli inventor of a “precision medicine” for COVID-19 is “very optimistic,” after an 88-person hospital trial entered its final day without a single patient ending up on a ventilator.


Placebo study still to come, but inventor says medication ‘could be a game changer’ after around 9 out of 10 participants in Greek trial are released from hospital within 5 days.

Marijuana-Like Brain Substance Calms Seizures but Increases After-Effects

Posted by in categories: biotech/medical, chemistry, neuroscience

But 2-AG is almost immediately converted to arachidonic acid, a building block for inflammatory compounds called prostaglandins. The researchers showed that the ensuing increase in arachidonic acid levels resulted in the buildup of a particular variety of prostaglandin that causes constriction of tiny blood vessels in the brain where the seizure has induced thatprostaglandin’s production, cutting off oxygen supply to those brain areas.


Summary: The release of 2-AG, a natural endocannabinoid that is suggested to be the brain’s equivalent to THC, dampens down seizure activity but increases post-seizure oxygen deprivation in the brain.

New process yields more, purer RNA at a fraction of the cost

Posted by in categories: biotech/medical, chemistry

The problem with impure RNA is that it can trigger reactions, like swelling, that can be harmful, and even life-threatening. For example, impure RNA can cause inflammation in the lungs of a patient with cystic fibrosis. Conventionally manufactured RNA has to undergo a lengthy and expensive process of purification. “Rather than having to purify RNA,” says Craig Martin, the paper’s senior author and professor of chemistry at UMass, “we’ve figured out how to make clean RNA right from the start.”


Researchers at the University of Massachusetts Amherst recently unveiled their discovery of a new process for making RNA. The resulting RNA is purer, more copious and likely to be more cost-effective than any previous process could manage. This new technique removes the largest stumbling block on the path to next-generation RNA therapeutic drugs.

If DNA is the blueprint that tells the cells in our bodies what proteins to make and for what purposes, RNA is the messenger that carries DNA’s instruction to the actual -making machinery within each cell. Most of the time this process works flawlessly, but when it doesn’t, when the body can’t make a protein it needs, as in the case of a disease like cystic fibrosis, serious illness can result.

How mRNA Vaccines Work — Simply Explained

Posted by in category: biotech/medical

MRNA vaccines have to potential to end the COVID19 pandemic. How do they work? Are they safe? And how could they’ve been developed so quickly?

The main idea of mRNA vaccines is to trick our bodies to produce part of a virus. This kickstarts our immune response, without getting us sick. All that’s needed is a part of the virus’s DNA or RNA, packaged into mRNA. Cool!

Study Yields Tiny Targets for Healing Human Memory

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers believe they have found a cause of memory loss in epilepsy patients by recording single neurons in the brain.

The discovery could offer a way to measure the effectiveness of memory-restoring therapies including medications and deep-brain stimulation. It also could be a step toward recovering lost memory among patients with a variety of brain conditions.

Cognitive decline: Investigating dietary factors

Posted by in categories: biotech/medical, food, neuroscience

A great beginning, but more research is needed.


While there are treatments for temporarily alleviating the symptoms of dementia, there is currently no cure available. The search is therefore on to identify lifestyle factors, such as diet, that can reduce individuals’ risk of developing the condition.

Previous research into possible links between eating foods rich in flavonoids and reduced risk of cognitive decline later in life has been inconclusive, however.

This link shows a global tracker of the virus mostly the virus keeps evolving oddly enough unseen from most viruses. Also the virus doesn’t like extreme cold.


Since December 2019, the disease has spread to every continent and case numbers continue to rise.

Cats’ immune system can deal with SARS-CoV-2, shows study

Posted by in categories: biotech/medical, health

Circa 2020


On 8 May 2020, the Institute of Agrifood Research and Technology (IRTA) reported the case of the first cat infected with SARS-CoV-2 in Spain. It was a 4-year-old cat called Negrito, who lived with a family affected by COVID-19, with one case of death.

Coinciding with these facts, the animal presented severe respiratory difficulties and was taken to a veterinary hospital in Badalona (Barcelona), where it was diagnosed with hypertrophic cardiomyopathy. Due to a terminal condition the hospital decided to do a humanitarian euthanasia.
