Quantitative and qualitative assessment of maternal sexuality during pregnancy.

Objective To investigate the quantitative and qualitative measures of the complex relationship between sexuality and the pregnant state. Methods An anonymous questionnaire [comprising the Female Sexual Function Index questionnaire, the Evaluation and Nurturing Relationship Issues, Communication and Happiness (ENRICH) Marital Satisfaction Scale, scale of attitudes toward sexuality, the World Health Organization (WHO) Well-Being Index and the scale of body image] was given to 243 women during antenatal classes. Results We evaluated 200 primiparous women, with an average age of 30.

Low arylsulphatase A activity in the development of psychiatric disorders.

Previous studies have suggested that arylsulphatase A (ASA) deficiency may be present in psychiatric patients. A number of patients with low ASA activity and various neuropsychiatric symptoms have been observed. Metachromatic leucodystrophy (MLD) is a disease caused by deficiency of the enzyme ASA.

Expression of neutral glycosphingolipids and gangliosides in human skeletal and heart muscle determined by indirect immunofluorescence staining.

The expression of neutral glycosphingolipids and gangliosides has been studied in human skeletal and heart muscle using indirect immunofluorescence microscopy. Transversal and longitudinal cryosections were immunostained with specific monoclonal and polyclonal antibodies against the neural glycosphingolipids lactosylceramide, globoside, Forssman glycosphingolipid, gangliotetraosylceramide, lacto-N-neotetraosylceramide and against the gangliosides GM3(Neu5Ac) and GM1(Neu5Ac). To confirm the lipid nature of positive staining, control sections were treated with methanol and chloroform:methanol (1:1) before immunostaining.

Cortical distribution of gangliosides in Alzheimer's disease.

In Alzheimer's disease, all ganglio-series gangliosides (GM1, GD1a, GD1b and GT1b) were found to be decreased in temporal and frontal cortex, and nucleus basalis of Meynert. In addition, in Alzheimer's disease simple gangliosides (GM2, GM3) were elevated in frontal and parietal cortex, possibly correlating to accelerated lysosomal degradation of gangliosides and/or astrogliosis occurring during neuronal death.
