PfeifFer (1945) posed an important problem concerning the metabolic effects of the corpus allatum hormone (CAH) when she demonstrated that allatectomy of the grasshopper Melanoplus leads to the massive accumulation of lipids and glycogen in the fat body. Other workers (e.g. Vogt, 1949; Thomsen, 1952; Bodenstein, 1953; Orr, 1964 a, b) have since found comparable effects after extirpating the cor...
We study the effect of the potential energy function on the global minimum structures of argon clusters arising in the optimization performed by genetic algorithms (GAs). We propose a robust and efficient GA which allows for the calculation of all of the putative global minima of Ar(N) (N = 3-78) clusters modeled with four different potentials. Both energetic and structural properties of such m...
During the last decade the study of topological effects formed by molecular systems became a routine but it was always carried out for configurations that were limited by symmetry conditions. To be more specific this applied to the Jahn-Teller (JT) effect formed by molecular configurations of planar symmetry [see, e.g., Baer et al., Faraday Discuss. 127, 337 (2004)] and the Renner-Teller effect...
streszczenie Zespół Pfeiffera (OMIM#101600) jest rzadkim zespołem uwarunkowanym genetycznie zaliczanym do dysostoz czaszkowo-twarzowych, który dziedziczy się w sposób autosomalnie dominujący ze zmienną ekspresją cech klinicznych. Występuje z częstością około 1:100 000 wśród żywo urodzonych dzieci. Typowe objawy zespołu obejmują: przedwczesne zarastanie szwów czaszkowych (kraniosynostoza), hipop...

Lars Holmberg and Andrew Vickers discuss the importance of ensuring prediction models lead to better decision making in light of new research into breast, endometrial, and ovarian cancer risk by Ruth Pfeiffer and colleagues. Please see later in the article for the Editors' Summary.
bacteriologists have become divided into two groups, those who considered the bacillus originally discovered by Pfeiffer to be the true infecting agent, and those who, as a cause, claim a minute ultramicroscopic virus so small that it passes through the finest filters. Recently two particularly valuable additions to our knowledge have been published, and they have tended so satisfactorily to re...
