Roger-Guy Werner (1901-1977)

Alors qu'il travaillait les lichens dans son laboratoire, chez lui à Nancy, le Professeur Werner s'écroula, victime d'une attaque cérébrale. Hospitalisé, il mourait quatre semaines après, le 28 mars 1977. Son travail, consacré surtout à la cryptogamie, et notamment à la recherche lichénologique, l'avait donc accompagné jusqu'à la fin de sa vie.

Isomerismo cis-trans: de Werner aos nossos dias

In coordination chemistry the study of geometrical isomerization and reactivity of specific isomers is a topic of major importance. The preparation of specific isomers often requires considerable complexity, and it is important to acquire a sense of what is involved in studying isomerism in laboratory. If it is difficult sometimes to prepare pure isomers, it is not easier to understand the mechanisms of isomerization reactions since studies on this subject have shown conflicting results and diferent interpretations on the same system have been reported in the literature. Although cis-trans isomerism in octahedral metal complexes is a common occurrence, there are relatively few studies reporting how these isomerizations occur. This paper gives an overview on cis-trans isomerization processes and identification of these species.

Alfred Werner e Heinrich Rheinboldt: genealogia e legado científico

The centenary of Alfred Werner's Nobel Prize in Chemistry has prompted this retrospect on his important contributions for the development of stereochemistry and for the understanding of the nature of the coordination compounds. His genealogy has been described, including a discussion on the famous Jørgensen-Werner controversy. As an extension, it has also been reported the German biography of Heinrich Rheinboldt, the founder of the Chemistry School at the University of São Paulo, and his relation with Werner's scientific heritage.

Herlyn-Werner-Wunderlich syndrome: a case report

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital disorder of the Müllerian ducts in which there is uterus didelphys, obstructed hemivagina and unilateral renal agenesis. The most common presentation is an abdominal mass secondary to hematocolpos, pain and dysmenorrhea. However, in some cases, such as the one we present here, menses are normal due to an obstructed hemivagina, and diagnosis can be delayed. We describe evaluation and surgical management of a 13-year-old girl with this condition who was diagnosed by computed tomography (CT) scan and confirmed by pelvic ultrasound and surgical exploration, as well as a review of the literature.
