Mounting evidence suggests that good sleep is critical to many aspects of our health. Circadian rhythms regulate the sleep-wake cycle in everything from mammals to fruit flies to plants, and keeps them synced up to the 24-hour cycle of the Earth’s rotation. In humans, circadian rhythms can be disrupted by chronic jet lag and shift work. New research indicates that disrupting these rhythms has negative consequences for both tumor size and microenvironment in mice.
In the world of monoclonal antibodies, being small is a big deal. Smaller antibodies and antibody fragments can penetrate solid tumors that would be inaccessible to larger antibodies, and some can even make it across the blood-brain barrier. That’s why it’s exciting that researchers at the University of Bath and UCB (a Belgian biotech company) have designed extra-small antibody fragments from cows.
Researchers led by UCLA’s Helen E. Vuong have determined that the presence of specific bacteria in the gut of pregnant mice can lead to long-term behavioral changes in the mice’s offspring. The group’s work contributes to the growing understanding of the relationship between gut bacteria and brain development.
People with type I diabetes are unable to make the insulin needed to regulate their blood sugar, which is why they must take exogenous insulin every day. Another treatment option is pancreatic islet transplantation, wherein healthy donor islets (tiny structures which contain insulin-producing beta cells) are transplanted into the diabetic patient.
A research team at MIT, led by Dr. Kripa Varanasi, has figured out a way around one of the major barriers to the delivery of concentrated biologic drugs.
Researchers at Duke University have developed a simple, low-cost method to assess the efficacy of different face masks at reducing the transmission of respiratory droplets during normal speech. Respiratory droplets are believed to be the primary way that people spread SARS-CoV-2 to one another.
Researchers at Pohang University of Science & Technology have developed a novel technique to affinity tag and purify recombinant proteins. Their method does not rely on protein-based affinity ligands, but rather utilizes cucurbiturils, a family of macrocyclic molecules named after their resemblance to pumpkins (family Cucurbitaceae).
Development of COVID-19 vaccines is moving forward at an unprecedented pace, and the public interest and press coverage are huge. And yet it is not easy for lay person or scientist to keep track of the multitude of vaccine candidates.
Mitochondria, the organelles that produce most of a cell’s energy, are distinguished from other organelles by having their own genetic information which is independent of the nucleus. The mitochondrial genome encodes for only 13 proteins, but these proteins are not only very important for energy generation; mutations in these genes are known to be responsible for a number of inherited diseases and they have been implicated in metabolic diseases, aging and neurodegeneration.
Scientists at Hokkaido University have published research on the effects of chemotherapy on the cells that line the blood vessels inside tumors. They found that, in response to first-line chemotherapy, these tumor endothelial cells (TEC) can become drug-resistant, which allows the tumors themselves to survive chemotherapy and metastasize.
