The observed distribution has an excess in the 120-160 GeV/c^2 mass range which is not described by current theoretical predictions within the statistical and systematic uncertainties. They found a new particle, in other words. Possibly. Open-source chemistry – Nothing beats ChemDraw…apparently…but if you're on Linux, you're stuck. Simply doing a search in the Ubuntu Software Installer for chemical drawing software turns up quite a few results, often with confusingly similar names ...

How long should you wait after treatment to dye your hair? Also, does the dye provide any lice protection? The Left Brain is picky about nits: Thanks for your questions, Fawn. Hopefully these answers will help: Without going into a lot of hair dye history, let’s just say that you should avoid using ANY shampoo on freshly dyed hair. That’s because the washing process removes a lot of dye. If you can, wait at least a couple of days before you shampoo. You can have your hair dyed the next day after lice treatment. The active ingredients will essentially be washed away when you shampoo again. And even if a little is left behind, that... thebeautybrains.com blogs http://www.medworm.com/rss/comments.php?id=4361125 Tue, 18 Jan 2011 06:01:25 +0100 4361125 http://www.medworm.com/index.php?rid=4214277&cid=t_131003_113_f&fid=39278&url=http%3A%2F%2Fblogsite.mdbuyline.com%2F%3Fp%3D105 According to a recent article, more than half ($15 billion) of the $21 billion U.S. Medical Imaging Market is spent on contrast agents. In fact, most hospitals spend as much on contrast agents as they do on new imaging equipment.  But with discounting ranging from 20 to 65%, this is an area that should not stay hidden.  On average, imaging dyes range from $20 to $150 per procedure and can make up 10 to 60% of a study’s costs.  When I spoke to Dr. Alexander R. Margulis, MD, clinical professor of radiology, Weil Medical College at Cornell University New York, he put it into perspective, stating, “Considering the overall expenses of a study, including hospital and doctors’ fees, the contrast is not much more.  If you address cost from just the technology side, it can start to add up...

They found no difference in the efficacy of the two therapies. LPDL is well established for treating rosacea’s facial redness (erythema) and visible blood vessels (telangiectasis), but not for treating inflammatory bumps and pimples (papulopustular eruptions). Recent preliminary evidence has suggested, howver, that topical photodynamic therapy (PDT) may be useful in treating papulopustular rosacea. The authors ...

I’m starting to wonder now if one of these days it’ll catch up to me. Unfortunately, I’m usually pretty impatient with my hair dye and don’t budget in time for a 48-hour-long test before wanting to color my hair. How common are such allergies, anyway? Also, The instructions say not to cover the test patch on your arm for 48 hours. What if I need to wear a long-sleeved shirt or sweater? Will that alter the allergy test results somehow? Ok, last question, I promise… I’ve noticed a new warning that those with tattoos may be more suceptible to experiencing an allergy from using hair dye. Is that true for a tattoo anywhere on the body, eve... thebeautybrains.com blogs http://www.medworm.com/rss/comments.php?id=4133972 Wed, 03 Nov 2010 06:01:35 +0100 4133972 http://www.medworm.com/index.php?rid=4040564&cid=t_131003_87_f&fid=39187&url=http%3A%2F%2Fgetbetterhealth.com%2Fdiabetes-lessons%2F2010.10.07 As doctors, sometimes the biggest lessons that we learn about disease pathology are those that we learn from the people that have that disease. Diabetes is one such disease. I recently gave a show-and-tell lecture about insulin pumps to the new interns and residents as well as the 3rd-year medical students on their pediatric clerkship with the inpatient endocrine service. We discussed different types of pumps (point A on the picture) and they got to push the buttons and send a bolus or change a basal rate. They also looked at real time CGM (Continuous Glucose Monitors, points C and D on the picture) sensors used to check glucoses levels every five minutes.

But it is. Researchers have experimented with rats suffering spinal cord injuries and have found a way to have them walk again with a limp. The “cure” for these rats came in the form of blue dye. Brilliant Blue G (BBG), a compound that gives blue M&Ms and Gatorade its color, was used to “thwart the function of P2X7.” P2X7 is a molecule in the spinal cord that allows Adenosine triphosphate access to the spinal cord after an injury occurs. Motor neurons in the spinal cord then die, causing the patient paralysis. While this research has allowed rats the ability to walk again, researchers stress that it may not do the same for humans. However, ...

Patients receiving this test will receive the same amount of radiation, which is found in other standard test such as nuclear stress test. When patients undergo CT scans they receive radiation equivalent 600 chest X-rays. The amount of radiation that that is given to a patient depends on where your health care provider sends you to have the CT scan. Some medical facilities take into consideration the size of the patient, when deciding on the dosage. The smaller the patient, the smaller the dosage. The technician may also pinpoint the radiation to the specific portion of the heart, which shortens the patient’s exposure. Find more on the the...

The measuring of the blood flow can determine where stents need to be implanted. Studies have shown that this new method is more effective than X-Ray examinations. If you are considering having this procedure, your health care provider should be made aware of any problems.  Let them know if you have an allergy to shellfish or intravenous dye, have diabetes or kidney disease.

What do they have in common?  They all worked at Bell Labs, and they all do imaging in rodent somatosensory cortex.  Primary somatosensory cortex (SI), particularly barrel cortex has many advantages. You can directly observe the input (whisker touching), you can get behavioral output, the cortex is smooth, has a vivid characteristic pattern of cytochrome oxidase staining and is accessible to a cortical window. Consequently, SI is one of the best characterized regions of cortex.  Far less understood is the structure and function of secondary somatosensory cortex (SII), but it likely plays an essential role in rodent sensory p...

Each area has a complete map of the entire visual field.  He combines triplet injections of Di-I, Di-O and BDA as fiducial markers with a label for callosal connections. He fixes the tissue in a manner that allows the unrolling and flattening of the entire mouse cortex. This allows him to segment and show the orientation of each field in a single cortical layer in the same slice. Different layers give different patterns of projection. Given the richness of the data obtained, I’m surprised that more systems neuros...

There is just one problem, Zhu and ... Brain Windows blogs http://www.medworm.com/rss/comments.php?id=1975208 Wed, 19 Nov 2008 21:10:23 +0100 1975208
