- This paper reviews the files in the archive of the Nobel Prize Committee for Physiology or Medicine on the Austrian physiologist and pioneering researcher in the emerging fields of urology and sexual medicine: Eugen Steinach (1861–1944). It reconstructs and analyzes why and by whom Steinach was nominated for the Nobel Prize between 1920 and 1938 and discusses the reasons why he never received the award, although the Nobel Committee judged him as prizeworthy. Steinach’s Nobel nominee career is extraordinary – not only because of his strong support by renowned international nominators from different scientific and medical disciplines, but also because of the controversial discussions within the Nobel Committee on his achievements, colored by the debates in the international scientific community. The Nobel Prize story adds a new perspective on how contemporary international scholars evaluated Steinach’s research on reproduction, “male-making” females, “female-making” males, homosexuality, and the concept of rejuvenation.

- The purpose of this study in a small group of non-stone-forming Chinese persons was to measure the levels of supersaturation with calcium oxalate and calcium phosphate and pH with the aim of confirming if any of the different short-term urine samples were better for risk evaluation than a 24-h sample. Nine normal men and 1 woman collected urine during 4 periods of the day. <i>Period 1</i> between 08 and 12 h, <i>Period 2</i> between 12 and 18 h, <i>Period 3</i> between 18 and 22 h, and <i>Period 4</i> between 22 and 08 h. Each sample was analysed for calcium, oxalate, citrate, magnesium and phosphate, and estimates of supersaturation with calcium oxalate (CaOx) and calcium phosphate (CaP) were expressed in terms of AP(CaOx) and AP(CaP) index. An estimate of the solute load of CaOx was also calculated. Urine composition for 24-h urine (<i>Period 24</i>) was obtained mathematically from the analysed variables. Urine composition corresponding to 14-h urine portions 22–12 h (<i>Period 14</i>N) and 08–22 h (<i>Period 14 D</i>) were calculated. The lowest pH levels were recorded in <i>Period 1</i> urine. The highest level of AP(CaOx) index was recorded during <i>Period 1</i>, and the product AP(CaOx) index × 10<sup>7</sup> × hydrogen ion concentration was significantly higher in Period 1 urine than in 24-h urine (<i>p</i> = 0.02). Also, the product SL(CaOx) × 10<sup>7</sup> × hydrogen ion concentration was significantly higher in <i>Period 1</i> urine (<i>p</i> = 0.02). Low AP (CaP) index levels were recorded in <i>Period 4</i>, but also in all periods following dietary loads of calcium and phosphate. With the important reservation that the analytical results were obtained from non-stone-forming persons, the conclusion is that analysis of urine samples collected between 08 and 12 h might be an alternative to 24-h urine. The risk evaluation might advantageously be expressed either in terms of the product AP(CaOx) index × 10<sup>7</sup> × hydrogen ion concentration or the product SL(CaOx) × 10<sup>7</sup> × hydrogen ion concentration.
