1. New Research Shows Pain-Relieving Effects of CBD


Source: Syracuse University 25 Apr 2021


While users tout cannabidiol’s (CBD) effectiveness in pain relief, up until now there’s been limited experimental human research on the actual effectiveness of the drug. However, a new study sheds light on the ability of CBD to reduce pain along with the impact that the so-called placebo effect may have on pain outcomes.

2. Skin and Bones Repaired by Bioprinting During Surgery

Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.

3. Researchers Identify Protein Produced After Stroke That Triggers Neurodegeneration

Researchers have identified a new protein implicated in cell death that provides a potential therapeutic target that could prevent or delay the progress of neurodegenerative diseases following a stroke. The scientists identified and named AIF3, an alternate form of the apoptosis-inducing factor (AIF), a protein that is critical for maintaining normal mitochondrial function. Once released from mitochondria, AIF triggers processes that induce a type of programmed cell death.

4. A New Treatment That Might Keep COVID-19 Patients Off the Ventilator

A new treatment is among the first known to reduce the severity of acute respiratory distress syndrome caused by the flu in animals, according to a new study. Tests in mice infected with high doses of influenza showed that the treatment could improve lung function in very sick mice and prevent progression of disease in mice that were pre-emptively treated after being exposed to the flu. The hope is that it may also help humans infected with the flu, and potentially other causes of acute respiratory distress syndrome (ARDS) such as SARS-CoV-2 infection.

5. Scientists Design ‘Nanotraps’ To Catch and Clear Coronavirus from Tissue

Researchers have designed a completely novel potential treatment for COVID-19: nanoparticles that capture SARS-CoV-2 viruses within the body and then use the body’s own immune system to destroy them. These “nanotraps” attract the virus by mimicking the target cells the virus infects. When the virus binds to the nanotraps, the traps then sequester the virus from other cells and target it for destruction by the immune system.

6. Scientists Reveal How Brain Cells in Alzheimer’s Go Awry, Lose Their Identity

Despite the prevalence of Alzheimer’s, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists have uncovered new insights into what goes awry during Alzheimer’s by growing neurons that resemble—more accurately than ever before—brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.

7. Major Advance Enables Study of Genetic Mutations in Any Tissue

For the first time, scientists are able to study changes in the DNA of any human tissue, following the resolution of long-standing technical challenges. The new method, called nanorate sequencing (NanoSeq), makes it possible to study how genetic changes occur in human tissues with unprecedented accuracy.

8. Draining Brain’s Debris Enhances Alzheimer’s Therapies in Mice

Experimental Alzheimer’s drugs have shown little success in slowing declines in memory and thinking, leaving scientists searching for explanations. But new research in mice has shown that some investigational Alzheimer’s therapies are more effective when paired with a treatment geared toward improving drainage of fluid — and debris — from the brain, according to a study led by researchers.

9. Preclinical Discovery Triggers Wound Healing, Skin Regeneration

Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The research team documented restoration of skin integrity, hair follicles, sweat glands, skin oils and normal hydration.

10. New Genetic Target for Blood Cancer Treatment

Targeting a pathway that is essential for the survival of certain types of acute myeloid leukaemia could provide a new therapy avenue for patients, the latest research has found. The researchers found that a specific genetic mutation, which is linked with poor prognosis in blood cancer, is involved in the development of the disease when combined with other mutations in mice and human cell lines.

11. A Third of Kids Develop A Mental Health Problem After Concussion

A third of children and adolescents develop a mental health problem after a concussion, which could persist for several years post-injury, according to a new literature review. The research found mental health should be evaluated as part of standard pediatric concussion assessment and management. The researchers said despite many post-concussion and mental health symptoms overlapping, the relationship between delayed recovery and mental health had remained poorly understood until this literature review.

12. New Gene Editing Technique Enables Millions of Genetic Experiments to Be Performed Simultaneously

Researchers have created a new gene editing tool called Retron Library Recombineering (RLR) that generates up to millions of mutations simultaneously, and “barcodes” mutant cells so that the entire pool can be screened at once, enabling massive amounts of data to be easily generated and analyzed.
