Brain development is surprisingly similar between humans and other primates

Rockville, Md. (April 27, 2021)--Although bronchopulmonary dysplasia (BPD)--a chronic lung disease affecting newborns--is the most common complication of preterm birth, it remains difficult to diagnose and treat. Researchers from Fundación INFANT in Buenos Aires, Argentina, and The University of Oklahoma Health Sciences Center, hope to address these difficulties using machine learning to inform the clinical care of preemies with BPD. The team will present their work virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021. BPD affects between 20% and 40% of all infants with birthweight below 3 pounds, 4 ounces (1,500 grams). It usually subsides by age ...

A new study found that non-pungent synthetic analog of capsaicin -- the compound that makes chili peppers hot -- made small cell lung cancer cells more responsive to treatment. Small cell lung cancer is a very aggressive form of cancer with a low survival rate. Cisplatin-based combination chemotherapy is typically the first-line treatment for small cell lung cancer patients. Although patients initially respond very well to this chemotherapy, the tumor usually comes back within a year in a form that doesn't respond to treatments. Patients with relapsed small cell lung cancer have very few treatment options. "Irinotecan is the only FDA approved second-line drug for small cell lung cancer, but less than 3% of patients respond to it," said research team leader Piyali Dasgupta, ...

New research conducted in rats suggests a compound that gives some cruciferous vegetables their pungent taste could help to reverse kidney problems associated with diabetes. It is estimated that about one-quarter of people with diabetes will eventually develop diabetic nephropathy, a gradual loss of kidney function eventually requiring dialysis. The condition is a leading cause of chronic kidney disease in the U.S. and is also associated with a high risk of heart disease. There is currently no cure. For the new study, researchers assessed the effects of phenethyl isothiocyanate (PEITC) in rats with diabetic nephropathy. PEITC is found in several types of vegetables but is most concentrated ...

Corals are part of a highly complex ecosystem, but it remains a mystery if and how they might communicate within their biological community. In a new study, researchers found evidence of sound-related genes in corals, suggesting that the marine invertebrates could use sound to interact with their surroundings. Coral reefs make up less than 1% of the ocean floor yet support more than 25% of all marine life. Around the world, coral reefs are being threatened by climate change, ocean acidification, diseases, overfishing and pollution. A better understanding of coral communication could help inform policies that aim to protect this critical ecosystem. "A growing number of studies have shown that trees can communicate, and that this communication is important for ecosystems such ...

The antidepression drug duloxetine could be beneficial to patients with both depression and cardiovascular disease, according to new studies performed in human blood and in mice. Globally, more than 300 million people have depression, which comes with an increased risk of developing cardiovascular disease. When a blood vessel is injured, the platelets in our blood respond by forming clots that stop blood bleeding. If this activation goes into overdrive, it can lead to thrombosis, a condition where blood clots form inside blood vessels and can dislodge to lead to a heart attack or stroke. In the new studies, researchers showed that duloxetine inhibited platelet function and protected ...

Results from a new cell study suggest that the SARS-CoV-2 spike protein can bring about long-term gene expression changes. The findings could help explain why some COVID-19 patients -- referred to as COVID long-haulers -- experience symptoms such as shortness of breath and dizziness long after clearing the infection. SARS-CoV-2, the virus that causes COVID-19, is covered in tiny spike proteins. During infection, the spike proteins bind with receptors on cells in our body, starting a process that allows the virus to release its genetic material into the inside of the healthy cell. "We found that exposure to the SARS-CoV-2 spike protein alone was enough to change ...

Findings from a new cell study suggest that the natural plant compound sanguinarine could be a promising tool for targeting triple-negative breast cancer cells. The researchers also found that breast cancer cells derived from people with African American ancestry were more sensitive to sanguinarine than those of European origin. "Triple negative breast cancer is especially aggressive in African American women, who are also more likely to develop this type of breast cancer than women of European descent," said Samia Messeha, PhD, a research associate in the College of Pharmacy and Pharmaceutical Science at Florida Agricultural and Mechanical ...
