Andrology Lab Corner* Receptors in Spermatozoa: Are They Real?

Sperm develop in the seminiferous tubules of testes following a complex developmental process called spermatogenesis. A series of morphologic remodeling occurs during spermiogenesis before the sperm are released into the lumen of the tubules by spermiation (Eddy and O’Brien, 1994). Mammalian testicular spermatozoa are relatively nonmotile and incapable of fertilizing an ovum. In most species, s...

Heegner Points: The Beginnings

Dick Gross and I were invited to talk about Heegner points from a historical point of view, and we agreed that I should talk first, dealing with the period before they became well known. I felt encouraged to indulge in some personal reminiscence of that period, particularly where I can support it by documentary evidence. I was fortunate enough to be working on the arithmetic of elliptic curves ...

Posterolateral Corner of the Knee:Current Concepts

       Injuries to the posterolateral corner (PLC) comprise a significant portion of knee ligament injuries. A high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. Moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. In this sense, stress radiographs can ...

The Beginnings of Astrobiology

With the present surge of interest in astrobiology and its emergence as a new scientific discipline in its own right, the role of a celebrated pioneer is all too often forgotten. There can be little doubt that the late Sir Fred Hoyle played a key part in relating astronomical phenomena to questions of life. One of his first contributions in this area was his introduction of the so-called anthro...
