    Sleep apnea

    Sleep apnea is when sufferer stops breathing (apnea) at night as the muscles in the throat relax and then resumes when brain semi-awakes when the oxygen supply gets low to restore respiration. This happens tens to hundreds of times at night and can be debilitating when the disruption to sleep causes other health effects such…

    Default mode network

    When we are not focused on a task, mind-wandering or just idling, specific regions of the brain such as medial pre frontal cortex, angular gyrus, hippocampus become activated and are called the default mode network. This is thought to be important for self referential thought, memory and future planning. It has been mapped with resting…

  • Developing a simple device and a Biomarker takes effort

    We had an interesting discussion with Dr Rebecca Fitzgerald, MD who is a Professor of Cancer Prevention at the University of Cambridge. Dr Fitzgeralds work aims to improve methods for early cancer detection for esophageal cancer through better understanding of the methods of molecular pathogenesis.She has developed many methods to quantify biomarkers in Barrett’s syndrome….

  • Filtering bacteria

    Multi Drug resistance to bacteria is a problem since bacteria continue dividing in blood causing sepsis that cannot be controlled by antibiotics and ultimately causing death. There have been multiple methods that have been proposed. A unique method has been published in Nature that incorporates “filtering” blood to remove the bacteria.Blood flows very rapidly through…

  • Autism and fever

    There have been studies, that show that in a significant proportion of Autistic patients the symptoms of Autism decreases when the patients have a fever, or are treated with an antibiotic – vancomycin. This effect has been known since about 1980 and (also reported on the web at Simons foundation too). When a fever ran…

  • Acuity measurement

    How does a hospital measure the acuity of an illness? Acuity is defined loosely as the severity of an illness. The more severe an illness or malady is the more attention it deserves. For example, chest pain is critical and deserves attention vs. flu like symptoms do not deserve as much attention. A doctor in…

  • Biomarker databases

    Biomarker database There are several databases that are used to track biomarkers. The important thing to keep in mind is that the biomarker may be biological entity like a protein, lipid or DNA/RNA fragment but they can also be a group of cells – for example Tumor infiltrating cells or, physiological test, clinical outcome measure…
