[Jean Bobon and the psychopathology of language].
In the field of "language psychopathology", Jean Bobon's works on delusional languages, specially his studies on neologisms and glossolalia, represent the most systematic collection of clinical observations up to date. In placing emphasis on the register of delusional speech acts, Bobon's research re-center language psychopathology around the concept of "signifier". It thus enables a psycho-analytical approach to clinical study of psychoses and its elaboration.
Human embryo chromosomes: preliminary results of a study to karyotype multipronuclear human oocytes fertilized in vitro.
Using special techniques the authors have analyzed the chromosome constitution of human gametes participating in fertilization in vitro. Only oocytes with multiple pronuclei have been used in this study. Two conclusions are reached by the Authors: first, that the gametes involved in the production of oocytes with multiple pronuclei can be chromosomally abnormal, specifically aneuploid and that not all oocytes with three pronuclei will cleave to form triploid embryos. The Authors underline that even normal, normospermically fertilized oocytes could have a chromosomal abnormality. They conclude that embryos with chromosomal abnormalities may be produced by IVF and ET and that their existence is reflected by the inability of the vast majority of transferred embryos to survive to term delivery.
Growth hormone--non multum sed multa (quality, not quantity).
In view of the recent availability of recombinant human growth hormone (GH) and reports of its ability to augment ovulation induction by exogenous gonadotropins, we have surveyed the reproductive physiological role of GH and the family of polypeptides that mediate its action. The clinical studies using GH to improve ovulation induction, although achieving a significant reduction in exogenous gonadotropin administration, show only minor benefits in terms of attainment of pregnancy. An explanation for this phenomenon is suggested, and we provide guidelines for whom GH should be recommended.
