Cancer Therapy by Silver Nanoparticles: Fiction or Reality?

Posted by in categories: biotech/medical, nanotechnology

As an emerging new class, metal nanoparticles and especially silver nanoparticles hold great potential in the field of cancer biology. Due to cancer-specific targeting, the consequently attenuated side-effects and the massive anti-cancer features render nanoparticle therapeutics desirable platforms for clinically relevant drug development. In this review, we highlight those characteristics of silver nanoparticle-based therapeutic concepts that are unique, exploitable, and achievable, as well as those that represent the critical hurdle in their advancement to clinical utilization. The collection of findings presented here will describe the features that distinguish silver nanoparticles from other anti-cancer agents and display the realistic opportunities and implications in oncotherapeutic innovations to find out whether cancer therapy by silver nanoparticles is fiction or reality.

The Essence of Lipoproteins in Cardiovascular Health and Diseases Treated by Photodynamic Therapy

Posted by in categories: biotech/medical, health

Lipids, together with lipoprotein particles, are the cause of atherosclerosis, which is a pathology of the cardiovascular system. In addition, it affects inflammatory processes and affects the vessels and heart. In pharmaceutical answer to this, statins are considered a first-stage treatment method to block cholesterol synthesis. Many times, additional drugs are also used with this method to lower lipid concentrations in order to achieve certain values of low-density lipoprotein (LDL) cholesterol. Recent advances in photodynamic therapy (PDT) as a new cancer treatment have gained the therapy much attention as a minimally invasive and highly selective method. Photodynamic therapy has been proven more effective than chemotherapy, radiotherapy, and immunotherapy alone in numerous studies.

Skin bacteria turned into topical vaccine, protects mice against tetanus

Posted by in categories: biotech/medical, health

It could lead to vaccines that could be simply rubbed onto the skin like creams.


Some bacteria, like harmless Staphylococcus epidermidis, have adapted to thrive on human skin.

Beyond batteries: Researchers bring body-heat powered wearable devices closer to reality

Posted by in categories: bioengineering, biotech/medical, robotics/AI, wearables

Noting that recent advances in artificial intelligence and the existence of large-scale experimental data about human biology have reached a critical mass, a team of researchers from Stanford University, Genentech, and the Chan-Zuckerberg Initiative says that science has an “unprecedented opportunity” to use artificial intelligence (AI) to create the world’s first virtual human cell. Such a cell would be able to represent and simulate the precise behavior of human biomolecules, cells, and, eventually, tissues and organs.

“Modeling human cells can be considered the holy grail of biology,” said Emma Lundberg, associate professor of bioengineering and of pathology in the schools of Engineering and Medicine at Stanford and a senior author of a new article in the journal Cell proposing a concerted, global effort to create the world’s first AI virtual cell. “AI offers the ability to learn directly from data and to move beyond assumptions and hunches to discover the emergent properties of complex biological systems.”

Scientists Discover Key Protein That Could Reverse Vascular Aging

Posted by in categories: biotech/medical, life extension

A recent study published in the journal Aging by Julia Michalkiewicz, Tung D. Nguyen, and Monica Y. Lee from the University of Illinois at Chicago College of Medicine underscores the essential role of the protein Nucleoporin93 (Nup93) in preserving blood vessel health during aging. The authors discuss emerging research that identifies Nup93 as a potential therapeutic target for preventing or mitigating aging-related conditions such as heart disease and stroke.

Cardiovascular diseases remain the leading causes of death worldwide, with aging identified as a major risk factor. Vascular health declines as endothelial cells (EC)—the protective lining of blood vessels—lose their functionality with age. This deterioration leads to inflammation, arterial stiffening, and reduced blood flow, significantly increasing the risk of life-threatening diseases. The authors underscore the urgent need to uncover the molecular mechanisms driving these changes.

Chimps use medicinal plants to treat illnesses, may help find new drugs

Posted by in categories: biotech/medical, futurism

The instrument uses light to move atoms to measure incredibly small forces.


A new study finds that chimpanzees’ self-medication has helped scientists identify some promising plants for future pharmaceuticals. In the study, Oxford researchers have identified no less than 13 plants with potent wound-healing and infection-fighting properties.

Stanford scientists transform ubiquitous skin bacterium into a topical vaccine

Posted by in categories: bioengineering, biotech/medical, health

Imagine a world in which a vaccine is a cream you rub onto your skin instead of a needle a health care worker pushes into your one of your muscles. Even better, it’s entirely pain-free and not followed by fever, swelling, redness or a sore arm. No standing in a long line to get it. Plus, it’s cheap.

Thanks to Stanford University researchers’ domestication of a bacterial species that hangs out on the skin of close to everyone on Earth, that vision could become a reality.

“We all hate needles — everybody does,” said Michael Fischbach, PhD, the Liu (Liao) Family Professor and a professor of bioengineering. “I haven’t found a single person who doesn’t like the idea that it’s possible to replace a shot with a cream.”
