‘Drug factory’ Implants Eliminate Ovarian, Colorectal Cancer in Mice

Immunotherapy treatment could begin human clinical trials this year. Rice University bioengineers have shown they can eradicate advanced-stage ovarian and colorectal cancer in mice in as little as six days with a treatment that could be ready for human clinical trials later this year.

The researchers used implantable “drug factories” the size of a pinhead to deliver continuous, high doses of interleukin2, a natural compound that activates white blood cells to fight cancer...

New Research Advances Wearable Medical Sensors

In recent research papers, Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics at Penn State, addresses challenges in the wearable health devices space, such as using materials that can withstand humid environments and integrating self-charging technology. Credit: Kate Myers. All Rights Reserved.

Self-powered sensors are key to more accurate, continuous health monitoring. Monitoring vitals and diagnosing ailments can be clunky, painful and inconvenient. But researchers like Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Assistant Professor of Engineering Science and Mechanics at Penn State, are working to improve health monitoring by creating wearable sensors that collect data for clinicians while limiting discomfort for patients.

30-60 mins of Weekly Muscle Strengthening Activity linked to 10-20% Lower Death Risk

Between 30 and 60 minutes of muscle strengthening activity every week is linked to a 10-20% lower risk of death from all causes, and from cardiovascular disease, diabetes, and cancer, in particular, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine.

The findings are independent of aerobic exercise. But the analysis points to a J-shaped curve for most outcomes, with no conclusive evidence that more than an hour a week of muscle strengthening activity reduces the risk further still.

Physical activity guidelines recommend regular muscle strengthening activities for adults, primarily because of the known benefits for skeletal muscle health...

Bark of Neem Tree may Protect Against Coronavirus Variants, study finds

New research reveals Neem-based drugs may help fight future coronavirus variants. Extract from the bark of the Neem tree may help treat and reduce the spread of coronavirus, according to a new study led by scientists at the University of Colorado Anschutz Medical Campus and the Indian Institute of Science Education and Research Kolkata.

The study, reported recently in the journal Virology, shows that components of Neem bark may target a wide range of viral proteins, suggesting its potential as an antiviral agent against emerging variants of coronaviruses (including SARS-CoV-2).

The Neem tree, indigenous to India, has been used for thousands of years for its anti-parasitic, anti-bacterial and antiviral properties...
