Strain

 

a pure culture of a species of microorganism in which its morphological and physiological characteristics are studied.

Strains can be isolated from a variety of sources, for example, soil, water, or food, or they can be isolated from a single source at different times. Hence, the same species of bacterium, yeast, or microscopic fungus may have a great many strains, differing from one another in several characteristics, such as sensitivity to antibiotics and capacity to produce toxins and enzymes. Commercial strains of microorganisms developed as a result of selection and used in industry for the microbiological synthesis of proteins (including enzymes), antibiotics, vitamins, and organic acids are much more productive than wild strains.

strain

[strān] (biology) An intraspecific group of organisms that possess only one or a few distinctive traits and are maintained as an artificial breeding group. (cell and molecular biology) A population of cells derived either from a primary culture or from a cell line by the selection or cloning of cells having specific properties or markers. (mechanics) Change in length of an object in some direction per unit undistorted length in some direction, not necessarily the same; the nine possible strains form a second-rank tensor.

strain

A change in the form or shape of a body or material which is subjected to an external force.

strain

Any deformation or deflection in a body caused by stress. The strain is directly proportional to the stress, as a load is applied until the proportional limit is reached. Beyond that point, the strain may increase at a changing rate until the yield stress is reached, but the part will return to its original size and shape when the load is removed and the strain is zero. The body will be deformed if the yield stress is exceeded. The strain is recorded as the change of size over the original size.

strain

11. Music a theme, melody, or tune 2. a feeling of tension and tiredness resulting from overwork, worry, etc.; stress 3. a particular style or recurring theme in speech or writing 4. Physics the change in dimension of a body under load expressed as the ratio of the total deflection or change in dimension to the original unloaded dimension. It may be a ratio of lengths, areas, or volumes

Patient discussion about strain

Q. My doctor advised me not to strain much. My doctor advised me not to strain much. What if I am physically unable to exercise due to a medical condition?A. Your doctor is more concerned about your health. So accept his advice and improve in your health. There is virtually no medical condition that will keep you from doing any type of exercise. Even people with heart failure -- who were long told not to exercise at all -- can benefit from moderate amounts of activity. And people with limited mobility can often do water exercises, or do yoga or other exercises while seated in a chair (some "chair exercise" videos are now on the market). Of course, if you have any medical condition, check with your doctor before starting any exercise program.

Q. shoulder and neck strain and pain I have a terrible shoulder and neck pain and i keep cracking my neck muscles to release pressure. I get temporary relief with tylenol but after few hrs the pain and strain starts again.Any ideas?A. A mellow exercise and streching on a regular basis is the best way to release a sore back and muscles in general, including your neck. You should try that plus applying local warm temperature (for example a warm pillow)around your neck. If that doesn't work then other anti-inflammatory drugs that you either apply as a cream or take as a pill can help you.

Q. any tips for low back strain? I'm an athlete, been having maaaajor lower back pain lately, during sports mainly but also when I just get out of bed in the morning. I was never like this- I'm really into sports and never felt so old in my life!!! Dont think the doctors really know their way with me, was hoping for some tips from your side. thanxA. Take Ibuprofen. I take 600mg and helps a lot. Also stretch like crazy -- three times a day if you can. Stretch you hamstring totally. You need to be very limber all the time. You should also lay off on exercising for a bit. Wait for the irritations to go down. Do tons of back and stomach exercises -- only after the irritation goes down. First thing in the morning is get out of bed, turn toward your bed,lift your leg on the bed and stretch you legs. Lots of things to do. Don't wait too long to see a doctor - it doesn't help not seeing a doc. The best a doc can do is give you an MRI. Xrays are ok but an MRI tells the story. I know, I had two back operations and have a bad back for 30 years (I am 49). Had my operations 7 months ago and now I lift almost every day (I don't lift as much -- just a lot of reps). Good luck.
