Antibodies from llamas could help in fight against COVID-19, study suggests

Posted by in category: biotech/medical

The researchers linked two copies of a special kind of antibody produced by llamas to create a new antibody that binds tightly to a key protein on the coronavirus that causes COVID-19. This protein, called the spike protein, allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture.

“This is one of the first antibodies known to neutralize SARS-CoV-2,” said Jason McLellan, associate professor of molecular biosciences at UT Austin and co-senior author, referring to the virus that causes COVID-19.

The team is now preparing to conduct preclinical studies in animals such as hamsters or nonhuman primates, with the hopes of next testing in humans. The goal is to develop a treatment that would help people soon after infection with the virus.

Snake stem cells used to create venom-producing organoids

Posted by in categories: biotech/medical, neuroscience

O,.o…


Organoids have become an important tool for studying many disease processes and testing potential drugs. Now, they are being used in a surprising and unexpected way: for the production of snake venom. On January 23 in the journal Cell, researchers are reporting that they have created organoids of the venom glands of the Cape coral snake (Aspidelaps lubricus cowlesi) and that these glands are capable of producing venom.

“More than 100,000 people die from snake bites every year, mostly in developing countries. Yet the methods for manufacturing antivenom haven’t changed since the 19th century,” says senior author Hans Clevers of the Hubrecht Institute for Developmental Biology and Stem Cell Research at Utrecht University in the Netherlands. “It’s clear there is a huge unmet medical need for new treatments.”

He adds: “Every snake has dozens of different components in their venom. These are extremely potent molecules that are designed to stop prey from running away. They affect systems as varied as the brain, neuromuscular junctions, blood coagulation, and more. Many of them have potential bioprospecting applications for new drugs.”

A Cost-Benefit Analysis of Intravenous Immunoglobulin Treatment in Children With Kawasaki Disease

Posted by in categories: biotech/medical, policy

To determine the long-term cost-benefit of intravenous immunoglobulin (IVIG) treatment in Children with Kawasaki Disease (KD), a model was made to compare the total cost for management of these children with and without the use of IVIG. Long-term (10−21 years) follow-up of 594 KD patients treated in the pre-IVIG era reported by Kato, et al. was used to calculate cost using previous cost studies from Chulalongkorn Hospital. Reduction of CAA from 25 per cent to 4 per cent with IVIG treatment was assumed based on previous published data. Total cost was slightly lower for the non-IVIG treatment group compared to the IVIG treatment group (33,451,129 baht vs 35,001,195 baht) for the duration of follow-up in Kato’s model. Cost per effectiveness analysis showed more effectiveness in the IVIG treatment group (359,576 baht vs 383,614 baht). Net cost analysis similarly demonstrated lower costs in the IVIG treatment group (25,365,215 baht vs 33,451,129 baht). Incremental cost-effectiveness analysis demonstrated supplementary costs of 13,663 baht for one case in the reduction of coronary involvement and 387,517 baht for one life saved in the IVIG-treated group. Estimation of total costs for follow-up and treatment for healthy life (until 60 years old) was more expensive in the non-IVIG treatment than the IVIG treated group (75,482,803 baht vs 29,883,833 baht). The authors conclude that treatment of all KD cases in Thailand with IVIG is likely to result in lower cost and better outcome when compared to no treatment with the IVIG policy.

Coronavirus vaccine update: List of countries that are closest to finding a treatment

Posted by in category: biotech/medical

Five months into the global outbreak, the world is racing against time to prepare a vaccine for coronavirus. Trials are underway in laboratories across the world with several companies and governments doubling their efforts to find a permanent cure for the deadly virus. World leaders and organisations, except the United States, have already pledged $8 billion to research, manufacture and distribute a possible vaccine and treatments for COVID-19 apart from the individual efforts taken by the countries and its pharmaceutical firms. We take a look at what are the major developments of the coronavirus vaccine happening across the globe.

Vitamin D appears to play role in COVID-19 mortality rates

Posted by in category: biotech/medical

After studying global data from the novel coronavirus (COVID-19) pandemic, researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates.

Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and clinics across China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the United Kingdom (UK) and the United States.

The researchers noted that patients from countries with high COVID-19 mortality rates, such as Italy, Spain and the UK, had lower levels of D compared to patients in countries that were not as severely affected.

Posted by in categories: biotech/medical, life extension

Your cells teem with small machinery and devices of all kinds, including teeny tiny batteries called mitochondria. Just like real batteries, they can malfunction, but replacing them isn’t that easy. In this episode, Veera explains what happens to our microbatteries with aging and what we can do about it.
