A tophus (Latin: "stone", pl.: tophi) is a deposit of monosodium urate crystals, in people with longstanding high levels of uric acid (urate) in the blood, a condition known as hyperuricemia. Tophi are pathognomonic for the disease gout. Most people with tophi have had previous attacks of acute arthritis, eventually leading to the formation of ...
Tophi is when uric acid crystals around the joints form larger, hard deposits. It can lead to pain, soft tissue damage, and joint deformities. Folks with gout are more prone to certain other ...
These tophi occur in 30% of those who are untreated for five years, often in the helix of the ear, over the olecranon processes, or on the Achilles tendons. [5] With aggressive treatment, they may dissolve.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The cohesive energy density is the amount of energy needed to completely remove a unit volume of molecules from their neighbours to infinite separation (an ideal gas). This is equal to the heat of vaporization of the compound divided by its molar volume in the condensed phase. In order for a material to dissolve, these same interactions need to ...
2. Eat Smaller, More Frequent Meals. Instead of three main meals, try eating smaller, more frequent meals throughout the day. This can help if nausea is making it hard to feel like eating or if ...
Photos show snarled traffic and crews at the scene evaluating the extent of the damage of the sinkhole that closed a section of Interstate 80.
Para block. The chemicals composing the block vary. The original formulations were based upon naphthalene and then later para-dichlorobenzene, both now known to be hazardous to health by inhalation.
