AChemS: the beginning. Association for Chemoreception Sciences

This paper unfolds the events, the people and the times that led up to thefounding of AChemS and fashioned its character during its early formativeyears. It describes the path over which AChemS came, going from theoriginal assertions and denials for the need of such an organization to itslater inception and nascent development. This narration highlights suchtopics as the debate over the need for AChemS, the role of National ScienceFoundation in the founding of AChemS, the derivation of the Association'sname, the choice of Sarasota and the Hyatt House as the meeting site, thegeneration of the programs for the early annual meetings, the adoption ofthe bylaws, the process of incorporation and tax deferment, and the birthof the Givaudan Lectureship. Most emphatically highlighted, however, is theenthusiasm, commitment and hard work that the members of the chemosensoryresearch community displayed in bringing AChemS to fruition.     

A natural history of a child with monosomy 5p syndrome (Cat-cry/Cri-du-chat syndrome) during the 18 years of follow-up

A record of a natural history of a long-term case study devoted to monosomy 5p (Cat-cry/Cri-du-chat) syndrome has been described rarely. Knowledge on the range of the changes in phenotype attributable to advancing age can be useful in clinical diagnosis of monosomy 5p at the different developmental stages, including adolescence, as well in prognosis for genetic counseling. In this case a detailed analysis of the morphologic phenotype in a girl with del(5)(p13.3) observed from 4 months to 18 years of age is reported. The comparative analysis of the girl's phenotype in different developmental stages has revealed that microcephaly, flat occipital region, face asymmetry, wide spaced palpebral fissures, epicanthic folds, small mouth fissure, thin mucous lip, small and low set ears and short IV metacarpals has not changed with advancing age. However, facial asymmetry was more evident, frontal tubers were less prominent, nasal root and back became prominent nasal back became elongated, the subnasal region was shorter and marked malocclusion appeared.     

The predictive value of transcranial duplex sonography for the clinical diagnosis in undiagnosed parkinsonian syndromes: comparison with SPECT scans

Background  

Transcranial duplex sonography (TCD) of the substantia nigra has emerged as a promising, non-invasive tool to diagnose idiopathic Parkinson's disease (IPD). However, its diagnostic accuracy in patients with undefined parkinsonism remains to be determined.     

Sterigmatocystin — incidence, fate and production byA versicolor in ras cheese

Sterigmatocystin (STG) is a toxic metabolite produced by severalAspergillus species. Because of its toxic and carcinogenic properties the occurrence of STG in food is considered to represent a potential hazard to man. The present study was designed to investigate following points:
