MRI Scans: Mri scans are performed on isolated parts of the body for specific reasons. If a physician is concerned for brain, spine or joint infections, than a targed MRI is a great test. It would never be used to screen a whole body. It would take hours and be very expensive. As an example, a brain MRI takes about 45 minutes. A total spine MRI takes up to 2.5 hours. ...Read more
Sometimes but not: Often. Egd examines esophagus, stomach, duodenum (technically small intestine, but only the very first part), and sometimes the first portion of jejunum, which is the true small intestine. The small intestine is about 30 feet long. Then there is the large intestine, or colon, for which you need colonoscopy. The middle 29+ feet is not accessble via endocsopy. ...Read more
Breathing: Respiration usually just means breathing. There is another more technical meaning when describing the biochemical processess within your body - "cellular respiration" is the process of combining oxygen inside your cells, in the mitochondria, where your cells create the chemical energy that drives your body. ...Read more
Map of Human DNA: The Human Genome Project created a map of human DNA and was completed in 2003. Anonymous samples were donated by several people, but the majority of the "genome map" is from a single male donor from Buffalo, NY. The identity of this individual is not known by researchers who sequenced the DNA. ...Read more

Is this UC? Colonoscopy report: PR normal. Granular mucosa in the rectum & sigmoid (reduced vascular pattern). Subtle rectal & sigmoid inflammation.
Ontogeny recapitul-: ates phylogeny. That means that during embryonic development, the embryo goes through physical forms that mimic your ancestors, rather than just develop right into a human. An early human embryo looks very much like our amphibian and then dinosaur (well, chicken, which is really the same thing) ancestors, and then many early structures wither and die, being replaced by more advanced species. ...Read more
"human pancreatic exocrine response to nutrients in health and disease" bmj 2005 figure 2 says lipase post-lundh meal should rise 5x. Is this correct?
Maybe, but...: That graph is a generalization, based on other scientists' studies (one would have to review the original studies). The graph shows pancreatic "enzyme delivery into the duodenum increases rapidly and reaches maximal values within the first postprandial hour", which means it's an estimate of the amount of enzyme put into the small intestine to digest food... Not a measure of lipase on a blood test. ...Read more

Some areas.: Upper endoscopy can look at the esophagus, stomach, and at least the 1st portion of the duodenum; also the opening where the bile exits. It cannot look at and therefore cannot diagnose problems in the remainder of the duodenum, the ileum or the jejunum. However, capsule endoscopy can look at these other areas. ...Read more
Incomplete versus : In 2000, the human genome project announced an assembled working draft of the sequence of the human genome. They assembled over lapping fragments covering 97% of the human genome. The draft was much more complete than they had expected--over 22.1 billion basis of raw sequence data totaling 7-fold sequence coverage. 24% was completely finished, and 50% in near finished or better form. ...Read more

What is HUMAN SOUL in MEDICAL Perception?Does MEDICINE/Science recognize existence of human soul.
Not clear: There is no clear scientific consensus about this, but many doctors and scientists DO, in fact, believe in a soul and in religion. ...Read more
The most commonly: performed operation that re-routes the intestines is the gastric bypass (the roux-en-Y gastric bypass). The duodenal switch also does this, but is much less common. The sleeve gastrectomy (vertical gastrectomy) and the lap band do not change the intestinal anatomy at all. However, the sleeve does remove approx 2/3 of the excess stomach. ...Read more
