In the East, the evolution of urethral catheters started with the firm establishment of Muslim supremacy, and by 1013, straight or one-curve catheters made of gold, silver, copper, lead or salve of white lead with a rounded end and many side holes and a stylet were the standard instruments. Then in Europe in 1853 a prototype of the Foley catheter was designed. The next im

Galaxy-Quasar Associations: Is the Big Bang Bung?
When we see a galaxy and a quasar near each other in the sky, it might be because they are really near each other, or it might be that they are far apart and just along the same line of sight. Tests performed by Alan Stockton (Astrophysical Journal 223:747-757, "The Nature of QSO Redshifts", 1978) on a sample of such pairs have shown that some galaxy-quasar pairs have the same redshift and so are accepted as being at the same distance. Other pairs with very different redshifts however have been

Lock and Key Binding of Testosterone to Cell Receptor Site
In this animation, anabolic steroid or its mimics, when injected, end up in circulation and bind with blood protein. Specific proteins (Androgen Receptor) in the muscle cells take up the steroid, undergoes structural changes and end up as a pair. This pair then translocates into the cell compartment (Nucleus), which houses the genetic material, comprising of thousands of genes.
