Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

What does this mean? "there is a shortened p-r interval consistent with an intra-nodal accessory pathway"

What does this mean? "there is a shortened p-r interval consistent with an intra-nodal accessory pathway"

Nodal conduction: "intra-nodal pathway"? You may have accelerated av nodal conduction from what is thought as inter-nodal pathways - three potential ones- from sinus node to the av node which is likely normal for age. If there is evidence of a delta wave than you may have wpw. Nodofasicular or nodoventricular pathways can give shortened pr intervals. Any palpitations? Have an electrophysiologist review your ecg. ...Read more

How can the allergy pathway work?

How can the allergy pathway work?

Allergies: Allergy is when your immune system mistakes a harmless substance for a dangerous one and triggers the release of chemicals from mast cells into your body, thus creating symptoms like runny nose, sneezing, watery eyes, and itching. When people who have allergies encounter an allergen, their immune system produces antibodies, called IgE antibodies, that are specific to that substance. ...Read more

Doc said over phone that my alternative (alternate) complement pathway is activated. What things could cause this? What does it mean?

Immune process: Complement proteins in the blood coat bacteria, viruses, etc., to make them easier for the immune system to grab onto and destroy. They can be activated by your own antibodies (classical pathway) or may spontaneously activate themselves (alternative pathway). Activation can mean anything from you are fighting an infection to you have an autoimmune process. Talk with your doctor for more info. ...Read more

I'm 36 and have 2 copies of APOE4 per Pathway Genomics. I have mild cognitive issues. What testing is appropriate that insurance will cover?

I'm 36 and have 2 copies of APOE4 per Pathway Genomics. I have mild cognitive issues. What testing is appropriate that insurance will cover?

Careful: Insurance ≠: Health. APOE4 =1 of multiple issues. Common larger issues: NMR-lipoproteins (see https://goo. Gl/Pqh6vp), HbA1c & ↑ed BP = primary drivers of arterial-disease, strokes & dementia. Optimize LDL: <400 nmol/L & Large-HDL: >9 umol/L, HbA1c <5.0% & Systolic BP <120 mmHg. Keep up with work of Jason Gestwicki & Leah Makley (https://www. Ucsf. Edu) on neurodegenerative diseases with dysfunctional proteins. ...Read more

My baby is 7 months old having severe optic pathway dysfunction Dr are investigating for mucopolysacchroidosis. What should I do plz help me.

Breathe and catch: Your breath until you know exactly what it is. Then work with the pediatrician to come up with a optimum treatment plan. Right now you must take care of you! If genetic, you can still affect postively the epigenetics (environmental, dietary impact) of the disease. Always get 2nd opinions too from an integrative medicine specialist! ...Read more

Can a hemorrhoid somewhat block the pathway of stool?

Can a hemorrhoid somewhat block the pathway of stool?

Yes. It can.: Yes if it is highly inflammed, enlarged or thrombosed. The fissure and pain further costrict the sphincter and make the passage of stool difficult. For constipation -walking exercise, high fiber diet, good water intake and MiraLAX (polyethylene glycol) are proven good. For hemorrhoid see your doctor. Thanks and good luck. ...Read more

Can you explain the cell signaling pathway involved in cystic fibrosis, what goes wrong, and the right way for it to work?

Can you explain the cell signaling pathway involved in cystic fibrosis, what goes wrong, and the right way for it to work?

CFTR: The cftr protein is on the surface of cells lining the lungs, intestine, pancreas, other organs. When activated by camp, a signaling molecule, it opens to release chloride from the inside of the cell. Water follows the chloride out of the cell. In cystic fibrosis, cftr is non-functional, so the mucus at the surface of the epithelial cell gets dehydrated and thick. ...Read more

Are binaural beats helpful in making new neural pathway connections in brain?

Are binaural beats helpful in making new neural pathway connections in brain?

No: Binaural beats have been studied for decades by neurophysiologists for clues to how the brain processes sensory input. Studies I've seen suggest that they MAY elicit transient alterations in some aspects of mood or cognition. I've seen NOTHING to substantiate the ludicrous claims made by the binaural-beat lunatic fringe on YouTube etc., whose enthusiasm far outstrips their understanding. ...Read more

What is the pathway of the blood from the renal artery to the renal vein?

What is the pathway of the blood from the renal artery to the renal vein?

Like: For any other organ / tissue the arteries bring blood, in this case the large renal artery, with oxygen and the waist products and splitsin the kidney into smaller and smaller branches that become eventually capillaries that connect with the venous capillaries that join biger end bigger vessels ending in the large renal vein, a branch of the vena cava that will end in the right heart. ...Read more

What are the treatments for under- or over-activation of the hormone pathway for leptin?

What are the treatments for under- or over-activation of the hormone pathway for leptin?

Weight management: Leptin is made by the fat cell and correlates strongly with weight/obesity. If you gain weight, fat cells get bigger, and leptin increases. Lose weight, and it goes down. Lose too much weight and it gets too low, and this accounts for the loss of menstruation in very thin women. ...Read more

What is the pathway tylenol (acetaminophen) takes through the body when administered through the rectum?

Tylenol (acetaminophen) absorpion: Hello ~ odd but interesting question. EXACTLY THE SAME ROUTE AS TAKING IT ORALLY, (or we wouldn't suggest taking it that way.) The rectal mucus membrane is exactly the same histologically as the mouth, so it gets absorbed thru the mmembrane, into the rectal veins into the internal iliac, into the coeliac vein and then the splenic vein AND portal v to liver. Metab in liver! Out in bile and duodenum.. ...Read more

My complement, alternative pathway test result =59% of norm. Standard range of lab >46% of norm. Is my result normal?

My complement, alternative pathway test result =59% of norm. Standard range of lab >46% of norm. Is my result normal?

Numbers are just...: Numbers are just numbers. Without the whole picture, such as why was labwork done, numbers usually cannot tell much. The result value in this question, shows that the result is in the "normal range" or "reference range". Therefore, the number 59 is "normal" (because it is bigger than 46) but one should ask her ordering doctor if the result is ok in the setting of her whole picture. ...Read more
