The experiments which finally led to the discovery of the phenomena which are now designated as "organizer-effect" were prompted by a question which actually goes back to the beginnings of developmental mechanics, indeed to the beginnings of the history of evolution in general. How does that harmonious interlocking of separate processes come about which makes up the complete process of developm...

Haloacetonitriles (HANs) are toxic nitrogenous drinking water disinfection byproducts (N-DBPs) and are observed with chlorine, chloramine, or chlorine dioxide disinfection. Using microplate-based Chinese hamster ovary (CHO) cell assays for chronic cytotoxicity and acute genotoxicity, we analyzed 7 HANs: iodoacetonitrile (IAN), bromoacetonitrile (BAN), dibromoacetonitrile (DBAN), bromochloroacet...

All the subjects were underwent oral glucose tolerance test (OGTT) for diagnosing T2DM, at the same time their clinical biochemical mar...

Hans Spemann [5] was an experimental embryologist best known for his transplantation studies [6] and as the originator of the ?organizer? concept. One of his earliest experiments involved constricting the blastomeres of a fertilized salamander [7] egg [8] with a noose of fine baby hair, resulting in a partially double embryo with two heads and one tail. Spemann continued changing variables such...

Hans Asperger studied mental abnormalities in children in Vienna, Austria, in the early twentieth century. Asperger was one of the early researchers who studied the syndrome that was later named after him, Asperger's Syndrome. Asperger described the syndrome in his 1944 publication Die Autistischen Psychopathen im Kindesalter (Autistic Psychopathy in Childhood). At that time, the syndrome was c...

The concept of polycentricity has gained significance in discussions on spatial development in Europe in recent years. This paper presents new evidence on polycentric city networks in Central-Eastern Europe based on selected results of the ESPON project POLYCE (Metropolisation and Polycentric Development in Central Europe). The authors discuss existing applications of the concept in the context...

was the case of 'Little Hans'. In 1905, Sigmund Freud described how phobias in the five-year-old boy had been treated analytically. From this starting point, a body of knowledge has been built up about disturbances in the behaviour pattern of children and adolescents and about the therapeutic methods for dealing with them in this way. Obviously, the child psychotherapist must know and understan...
