Arachidonic acid is an omega-6 fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain. It is the counterpart to the saturated arachidic acid found in peanut oil.
A potentially valuable new study discusses the role of lipids in the hyper-inflammatory phenomena that take place within the lungs of patients with severe or critical COVID-19. Involving a large variety of specialized lipids with biological activity, this process includes the generation and release of pro and anti-inflammatory lipids.
Like people, cells in the human body protect their personal space. They seem to know how much space they need, and if it gets too tight, most cells prefer to break free.
Type 1 diabetes, or T1D, is an autoimmune disease in which the body's immune cells -; led by inflammatory macrophages -; attack and destroy the beta cells of the pancreas that produce insulin.
Now, a new study published on the preprint server bioRxiv in June 2020 reports the discovery of a novel free fatty acid (FFA) binding pocket on the SARS-CoV-2 virus that could explain in part the viral effects of hyperinflammation, immune modulation, and membrane structure.
Camelina sativa oil and fatty fish are rich in polyunsaturated omega-3 fatty acids, but their health benefits seem to differ.
Infants born prematurely may require parenteral or intravenous nutrition to provide the necessary nourishment, as their digestive system is immature and cannot digest nutrients.
Black men and women have higher incidences than whites of developing advanced heart failure following a heart attack.
Researchers at the University of Campinas in São Paulo State, Brazil, have developed a computer program that analyzes molecules in blood plasma to search for biomarkers that identify individuals who are at risk of becoming overweight and developing obesity-related diseases.
For women receiving breast implants during reconstructive or cosmetic breast surgery, scarring around the implant - called capsular contracture - is a common, costly, and painful complication.
The Chan group at the Beckman Institute for Advanced Science and Technology has recently developed a probe named CoxFluor, which is able to distinguish between Cyclooxygenase-2, an enzyme that plays a major role in driving the progression of cancer, and Cyclooxygenase-1, which is expressed in all cells.
Global diagnostics company Randox Laboratories has unveiled an innovative new test for the risk assessment of cardiovascular disease at this year's AACC Clinical Lab Expo in Anaheim, California.
A pioneering new study suggests that babies born to obese or overweight women fail to grow properly during breastfeeding.
International group of scientists in the joint study of the laboratory of the Wistar Institute, University of Pittsburgh and I.M. Sechenov First Moscow State Medical University discovered the change in activity of one of the immune cells types called neutrophils during the cancer development: they begin to prevent other immune cells from fighting tumor and thus decelerate treatment.
Scientists from the Diabetes Research Institute at the University of Miami Miller School of Medicine today announced the launch of a new clinical trial that will assess the impact of high-dose omega-3 fatty acids and vitamin D supplementation on halting the progression of type 1 diabetes.
There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.
Could omega-6 fatty acids protect you against premature death? The answer is yes, according to a new University of Eastern Finland study. While protecting against death, omega-6 fatty acids also keep cardiovascular diseases at bay.
Now there is hope of a new way to protect extremely premature babies from impaired vision or blindness resulting from the eye disease retinopathy of prematurity.
Aggressive cancers like glioblastoma and metastatic breast cancer have in common a siren call that beckons the bone marrow to send along whatever the tumors need to survive and thrive.
New research from Karolinska Institutet in Sweden reveals that high levels of polyunsaturated fatty acids in children's blood are associated with a reduced risk of asthma or rhinitis at the age of 16 years. The study is published in The Journal of Allergy and Clinical Immunology.
A team of LSU Health New Orleans scientists discovered that a component of fish oil not only protects cells critical to vision from potentially lethal initial insults, but also from those that occur in the future.
