In 25, Corning used a "Knoop Visual Scratch Test," but the next year, it made no mention of scratch resistance at all, so we're unable to draw a line through the earlier glass generations.

That's how I ended up with a chair in my apartment that looks like this: So when Burrow — an online furniture company that ships sturdy, stylish and easy-to-construct furniture to your front door — said they had a chair that went through and passed an animal scratch test, I was ready to give it a try.

The Liver scratch test is a technique used by medical professionals during a physical exam to locate the inferior border of the liver in order to approximate the size of a patient's liver. The technique was first credited to Burton-Opitz in 1925 where it was used to identify the cardiac silhouette, however there are references of similar techniques used prior to this. The liver scratch test can be used when other exam techniques used to approximate liver size are ineffective and is thought to be most useful if the abdomen is distended, too tender for direct palpation, the abdominal muscles are too rigid, or the patient is obese.

Early diamond identification tests included a scratch test relying on the superior hardness of diamond. This test is destructive, as a diamond can scratch another diamond, and is rarely used nowadays. Instead, diamond identification relies on its superior thermal conductivity. Electronic thermal probes are widely used in the gemological centers to separate diamonds from their imitations.

Despite being commonly taught to medical trainees, the liver scratch test's value as part of the abdominal physical exam has been controversial as it has historically performed poorly. While it has been proposed to abandon the test altogether, some studies have suggested that the scratch test is at least as accurate as percussion overall in identifying the liver edge and even more accurate for young trainees.

Natural History XXXVII:23-29 Pliny returns to the problem of fraud and the detection of false gems using several tests, including the scratch test, where counterfeit gems can be marked by a steel file, and genuine ones not. Perhaps it refers to glass imitations of jewellery gemstones. He refers to using one hard mineral to scratch another, presaging the Mohs hardness scale. Diamond sits at the top of the series because, Pliny says, it will scratch all other minerals.

In most cases, a positive skin test is used in identification of allergies, but the activation of basophilic granulocytes with anti-IgE, the expression of the CD63 antigen on the cell surface (plasma membrane) allows identification of the allergen responsible for the hypersensitivity reaction without performing the common scratch test. Only a little amount of blood is needed for this experiment, which makes it comfortable to use since one can perform it in parallel to a normal blood checkup. It can be used for different allergies (e.g. bee venom, drugs, contrast mediaBöhm I et al.

Sometimes the entire edge of the magazine door is taped as an extra measure of light- tightness, although for newer properly maintained magazines this is not strictly necessary. Magazines must also be checked thoroughly before usage against the creation of scratches in the emulsion. This is usually done during camera checkout at a rental house with what is known as a scratch test, where junk film is run through the camera and then examined against light for scratching. On-set, cases with loaded magazines are often placed on standby near active cameras in order to facilitate fast magazine reloading with minimal lag time.

The liver scratch test is a type of auscultatory percussion that uses the difference in sound transmission between solid and hollow organs in the abdominal cavity in order to locate the inferior edge of the liver. The test is most commonly performed by placing the stethoscope below the xiphoid process and lightly scratching the skin parallel to the expected liver edge. The examiner begins scratching in the right lower quadrant of the abdomen along the midclavicular line and moves superiorly until the sound abruptly increases in volume. This location of suddenly increased auscultation volume is marked as the inferior edge of the liver and can then be used to determine the overall liver size.

High dose aspirin treatment (aspirin, at these doses, inhibits cyclooxygenases-1 and -2 to block their production of 12-HHT), thromboxane synthase knockout, and BLT2 receptor knockout but not TXA2 receptor knockout impair keratinocyte-based re-epithelialization and thereby closure of experimentally induced wounds in mice while a synthetic BLT2 receptor agonist accelerats wound closure not only in this mouse model but also in the db/db mouse model of obesity, diabetes, and dyslipidemia due to leptin receptor deficiency. 12-HHT accumulated in the wounds of the former mouse model. Companion studies using an in vitro scratch test assay indicated that 12-HHT stimulated human and mouse keratinocyte migration by a BLT2 receptor-dependent mechanism that involved the production of tumor necrosis factor α and metalloproteinases. These results indicate that the 12-HHT/BLT2 receptor axis is a critical contributor to wound healing in mice and possibly humans.
