Laboratory tests examine the biological, chemical and physical properties of the cells and molecules that make up a blood specimen. The first step is often to centrifuge a blood specimen into separate components. This divides the sample into one portion that contains solid components, such as cells...
pleural membranes - thin, membranes that cover the lungs, separate them from other organs and form a fluid-filled chest cavity. pulmonary capillaries - small blood vessels that surround each alveolus trachea -rigid tube that connects the mouth with the bronchi (windpipe) Breathing and the Autonomic...
Within the blood are also numerous molecules formed as byproducts of normal biochemical functions. When these molecules indicate how your cells areresponding to disease, injury or stress, scientists often refer to them asbiological markers, or biomarkers. Thus, biomarkers in a blood sample can repre...

and clinical trials on the use of statins and blood pressure medications to slow the progression of Alzheimer’s are being conducted. Another form of dementia separate from Alzheimer’s disease, vascular dementia, is directly caused by poor blood flow to the brain, so there is a clear link be...
Critics say companies that perform cryonics are simply bilking people out of their money with the promise of an immortality they cannot deliver. Even scientists who perform cryonics say they haven't successfully revived anyone -- and don't expect to be able to do so in the near future. One...
beats and repetitive noises. Pick out distinct sounds like individual birdsong. Notice also the sounds come from silence and return to silence. Be aware of the gaps as much as the sounds. Listen to music with your eyes closed. Try following two separate sounds individually. For the ultimate ...
In a different study, scientists found higher amounts of microscopic plastic particles in the feces of people with inflammatory bowel disease. While some recent studies are finding some associations between PFAS and microplastic exposure with serious medical conditions, Dr. Gerber says ...
