First approved targeted therapy for Gastric Cancer in Singapore offers new way and hope of treating disease

Lilly announced today that CYRAMZA® (ramucirumab) has been approved by the Singapore Health Sciences Authority to treat people with advanced gastric cancer, whose cancer has progressed after prior chemotherapy. First country in ASEAN to approve the new biologic therapy that extends survival in patients with advanced stomach cancer after prior chemotherapy

CYRAMZA® (ramucirumab) is now available to Singaporeans living with advanced gastric cancer. The drug gained approval by Singapore’s Health Science’s Authority (HSA) earlier this year, marking the first regulatory approval in ASEAN. CYRAMZA is already available to patients in Japan, Korea, Taiwan and Hong Kong.

Why Machines Should Go To The University of Google, School of Artificial Intelligence

Now that’s an idea; education for systems. I can see the online university advertisements now showing an autonomous car beeping and flashing its lights over the enjoyment of graduating.

What if I told you to tie your shoes, but you had no laces? Or to cook dinner, but you had no pots or pans.

There are certain tools we need to succeed, which we often don’t have access to or are held back by a gatekeeper.

Dozens of AI / Machine Learning startups experience this same problem because they don’t have enough data to properly train their AI algorithm. Startups that aim to eliminate the error involved in judging cancerous tumors. Startups that aim to improve personalized medicine and create a healthier future.

The power of polymeric coating

Nice write on polymeric coatings as a material option consider when developing implants replicating a natural electrode charge without creating damage or disruptions. Author proposes such materials could be leveraged beyond their use today and expanded to include BMI implants. Definitely, will take a closer look at.

Jeff Hendricks Biotectix outlines how polymeric coatings can help improve the performance of medical and consumer electronic devices.

Potential diabetes therapy: Engineered cells that control blood sugar

Excellent. Now, the question is “has Microsoft seen this?” as they are working on solving Diabetes too as part of their Synbio program that has already shown us their DNA Data Storage.

People with type 1 diabetes must inject themselves with insulin multiple times per day. This is because their immune system has destroyed cells in the pancreas that secrete insulin to maintain a healthy blood glucose level.

A team of bioengineers now report a possible alternative to such injections. The researchers engineered human kidney cells to act like pancreatic β cells, namely to sense blood glucose levels and produce insulin accordingly (Science 2016, DOI: 10.1126/science.aaf4006). When implanted in mice with type 1 diabetes, the cells prevent high blood glucose levels, also known as hyperglycemia.

Right now, “all we offer diabetic patients to cope with their disease is to have them measure their blood glucose levels and then inject a hormone,” says Martin Fussenegger of the Swiss Federal Institute of Technology, Zurich, who led the team that engineered the cells. Although this works, he says, getting the dose right can be tough. “We set out to pioneer a new disease treatment concept.”

A New Form of Synaptic Plasticity in Pain Pathways

Nice.

Chronic pain is thought to involve the long-lasting strengthening of synapses, akin to what happens during the formation of new memories. This phenomenon, known as long-term potentiation (LTP), is triggered when neurons on both sides of a synapse are active at the same time. But now, Jürgen Sandkühler, Medical University of Vienna, Austria, and colleagues provide evidence that LTP in nociceptive circuits arises in a different way.

By simultaneously activating two types of glial cells―astrocytes and microglia―the researchers were able to produce LTP at synapses that connect peripheral C-fibers and lamina I neurons in the dorsal horn spinal cord. They also showed that with high-frequency stimulation of C-fibers, glial cells strengthen active and inactive synapses through their release of the NMDA receptor co-agonist D-serine and the cytokine tumor necrosis factor (TNF). Moreover, these molecules traveled to distant synapses, perhaps explaining why pain hypersensitivity can develop in areas surrounding or far away from an injury.

“This paper is going to stimulate a lot of discussion that will lead to important advances for all of us in the pain field,” said Theodore Price, The University of Texas at Dallas, US, who was not involved in the study. “It raises questions for my lab in our day-to-day research that we can address immediately. That’s ultimately the true measure of a really good paper.”

Two electrons go on a quantum walk and end up in a qudit: Russian scientists find a way to reliably connect quantum elements

This is a BIG DEAL in QC, and Russian Scientists solved it.

Abstract: Scientists from the Institute of Physics and Technology of the Russian Academy of Sciences and MIPT have let two electrons loose in a system of quantum dots to create a quantum computer memory cell of a higher dimension than a qubit (a quantum bit). In their study published in Scientific Reports, the researchers demonstrate for the first time how quantum walks of several electrons can help to implement quantum computation.

“By studying the system with two electrons, we solved the problems faced in the general case of two identical interacting particles. This paves the way toward compact high-level quantum structures,” comments Leonid Fedichkin, Expert at the Russian Academy of Sciences, Vice-Director for Science at NIX (a Russian computer company), and Associate Professor at MIPT’s Department of Theoretical Physics.

In a matter of hours, a quantum computer would be able to hack through the most popular cryptosystem used even in your web browser. As far as more benevolent applications are concerned, a quantum computer would be capable of molecular modeling that takes into account all interactions between the particles involved. This in turn would enable the development of highly efficient solar cells and new drugs. To have practical applications, a quantum computer needs to incorporate hundreds or even thousands of qubits. And that is where it gets tricky.

The first-in-man clinical trial targeting Alzheimer’s Tau protein

Progress with Alzheimers and this time approaching it from the direction of Tau as a target rather than Beta Amyloid. This therapy has been tested in people and whilst it is only the first step hopefully this will lead to an effective treatment for this horrific diseases and and end to the suffering it brings.

Progress towards immunotherapies that can clear tau for Alzheimers here. Most therapies are focused on misfolded amyloid-β proteins but this particular approach targets Tau and the first in human test has proceeded!

“The authors of the study have developed a vaccine that stimulates the production of an antibody that specifically targets pathological tau, discovering its “Achilles’ heel”. It is able to do this because healthy tau undergoes a series of changes to its structure forming a new region that the antibody attacks. This new region (the “Achilles’ heel”), while not present in healthy tau, is present in diseased tau early on. Therefore, the antibody tackles all the different varieties of pathological tau. In addition to this important specificity, the antibody is coupled to a carrier molecule that generates a considerable immune response with the added benefit that it is not present in humans, thus avoiding the development of an immune reaction towards the body itself.”
