Osgood–Schlatter disease resolves or becomes asymptomatic in the majority of cases. One study showed that 90% of reported patients had symptom resolution in 12–24 months. Because of this short symptomatic period with most patients, the number of people who become diagnosed is a fraction of the true number.
Patella, its tendon and tibial tuberosity. The condition is usually seen in athletic individuals typically between 10 and 14 years of age.

The underlying property data for the Mollier diagram is identical to a psychrometric chart. At first inspection, there may appear little resemblance between the charts, but if the user rotates a chart ninety degrees and looks at it in a mirror, the resemblance is apparent. The Mollier diagram coordinates are enthalpy h and humidity ratio x.
The birth rate in America has long been on a decline, with the fertility rate reaching historic lows in 2023. More women between ages 25 to 44 aren’t having children, for a number of reasons.
Ribbon diagram of a heptameric, 63 kDa cleavage fragment (PA 63) of the protective antigen (PA) protein, produced by Bacillus anthracis as part of the anthrax toxin. The quaternary structure is that of a pre-pore, which later forms a channel that allows other toxins into the cytosol of the target cell, so the pathogen can cause damage to the host.
