When is pharmacogenomic testing useful in cancer care?

Posted by in categories: biotech/medical, food, genetics

Dr. Kimathi is a medical oncologist in a community setting where she sees patients with a variety of cancer diagnoses. Recently, she had several patients with toxicities to different treatments, including tamoxifen, cisplatin, and methotrexate. Concerned, she wondered if there was a common factor these patients shared to have experienced these toxicities. On review, she found that these patients had different cancer diagnoses and did not share any known comorbidities or risk factors.

Why do some cancer patients experience toxicities from certain treatments and others don’t? Drug metabolism is highly variable among patients, and even within the same patient, depending on age and disease state. Both the toxicity and efficacy of cancer chemotherapy can be affected by many different factors, including other medications, foods, dietary supplements, environmental conditions, and genetic variants in drug-metabolizing genes and drug transporters.

U.S. Aquifers Are Running Dry, Posing Major Threat to Drinking Water Supply

Posted by in categories: energy, food, law, sustainability

A major _New York Times_ investigation reveals how the United States’ aquifers are becoming severely depleted due to overuse in part from huge industrial farms and sprawling cities. The _Times_ reports that Kansas corn yields are plummeting due to a lack of water, there is not enough water to support the construction of new homes in parts of Phoenix, Arizona, and rivers across the country are drying up as aquifers are being drained far faster than they are refilling. “It can take millions of years to fill an aquifer, but they can be depleted in 50 years,” says Warigia Bowman, director of sustainable energy and natural resources law at the University of Tulsa College of Law. “All coastal regions in the United States are really being threatened by groundwater and aquifer problems.”

Scientists Electrify Biology by Converting Current Into the Chemical Fuel of Cells

Posted by in categories: biotech/medical, chemistry, food, genetics

Interfacing modern electronics-based technology with biology is notoriously difficult. One major stumbling block is that the way they are powered is very different. While most of our gadgets run on electrons, nature relies on the energy released when the chemical bonds of ATP are broken. Finding ways to convert between these two very different currencies of energy could be useful for a host of biotechnologies.

Genetically engineered microbes are already being used to produce various high-value chemicals and therapeutically useful proteins, and there are hopes they could soon help generate greener jet fuel, break down plastic waste, and even grow new foods in giant bioreactors. But at the minute, these processes are powered through an inefficient process of growing biomass, converting it to sugar, and feeding it to the microbes.

Now, researchers at the Max Planck Institute for Terrestrial Microbiology in Germany have devised a much more direct way to power biological processes. They have created an artificial metabolic pathway that can directly convert electricity into ATP using a cocktail of enzymes. And crucially, the process works in vitro and doesn’t rely on the native machinery of cells.

For the first time, AI dominates humanity’s best in a real-world sport

Posted by in categories: drones, food, robotics/AI

High-speed drone racing has just had a shocking “Deep Blue” moment, as an autonomous AI designed by University of Zurich researchers repeatedly forced three world champion-level pilots to eat its dust, showing uncanny precision in dynamic flight.

If you’ve ever watched a high-level drone race from the FPV perspective, you’ll know how much skill, speed, precision and dynamic control it takes. Like watching Formula One from the driver’s perspective, or on-board footage from the Isle of Man TT, it’s hard to imagine how a human brain can make calculations that quickly and respond to changing situations in real time. It’s incredibly impressive.

Air pollution from different emission sources is associated with incident dementia

Posted by in categories: food, life extension, neuroscience, policy, sustainability

NIH-funded study suggests reducing exposure to airborne particulates may decrease dementia risk.

Higher rates of new cases of dementia in a population over time — known as incident dementia — are linked to long-term exposure to fine particulate matter (PM2.5) air pollution, especially from agriculture and open fires, according to a study funded by the National Institutes of Health and published in JAMA Internal Medicine. Scientists found that 15% of older adults developed incident dementia during the average follow-up of 10 years.

“As we experience the effects of air pollution from wildfires and other emissions locally and internationally, these findings contribute to the strong evidence needed to best inform health and policy decisions,” said Richard J. Hodes, M.D., director, National Institute on Aging (NIA), part of NIH. “These results are an example of effectively using federally funded research data to help address critical health risks.”

Increasing the bioavailability of oncology drugs with amorphous solid dosage formulations

Posted by in categories: biotech/medical, food

Oral tyrosine kinase inhibitors (TKIs) are a class of cancer drugs that can be highly susceptible to issues with solubility in the gastrointestinal tract. Most crystalline TKI drugs have pH-dependent solubility that affects their bioavailability in an oral dosage form. Consequently, natural variations in gastric pH, or variations due to eating or taking antacids, can significantly impact drug absorption and, in turn, therapeutic efficacy.

Alternative formulation techniques such as amorphous solid dispersion (ASD) can still deliver the convenience of a pill while reducing TKIs’ sensitivity to physiological variation. This ensures more consistent—and higher—bioavailability. This whitepaper outlines the challenges associated with pH-dependent solubility for oral TKI drugs and reviews how leveraging ASD formulation can help create more effective, patient-friendly drug products.
