    Notizen: Abstract We recently reported on a new fetal rat model of esophageal atresia (EA) with tracheoesophageal fistula (TEF) induced by prenatal exposure to adriamycin (1.75 mg/kg i. p. injected daily to the pregnant dam from the 6th to 9th gestational days). With this treatment regime, many fetuses were resorbed and the number of associated malformations was very high. The present study demonstrates that similar doses of the drug administered only on the 8th and 9th gestational days allow higher fetal survival (9.7 ∓ 3.9 vs. 6.8 ∓ 4.7 fetuses per litter, P 〈 0.01) with a similar incidence of EA-TEF (41.2% vs. 56.4%, n. s.) and decreased occurence of associated anorectal and genitourinary malformations. Since this model is an instrument for further investigation of the disturbed cellular and morphogenetic events leading to EA and TEF, the narrowing of the embryologic window obtained by the present study will allow better focusing of the research on the critical period of time involved.

    Notizen: Abstract Verrucose dysplasias, found at autopsy in the cerebral cortex of three elderly individuals (two without neurological disorders and one with motor neuron disease), are shown to present neurofibrillary degeneration of Alzheimer's disease type. This neurofibrillary degeneration immunoreacted with antibodies against abnormally phosphorylated tau (5E2 and AT8), disclosed acetyl- and butyrylcholinesterase activity, and was consistently stained with thioflavin-S. Cortical dysplasias, found either as isolated verrucose nodules or comprising multiple nodules, contained cell-sparse areas around which a peak of neurofibrillary changes was seen. Cell-sparse areas were sometimes bridged by stripes of neurons and fibers arranged in a radial fashion, and many of these neurons showed neurofibrillary degeneration. Cytoskeletal abnormalities were conspicuous in layers II and III at the external borders of the dysplasias, as well as in neurons located in layers V and VI, and in the white matter beneath layer VI in central zones of each lesion. The morphology of cells undergoing neurofibrillary changes (from early non-fibrillar stages to late extracellular ones) suggests that neurons disturbed in their migration toward the site to which they had been committed may become vulnerable to cytoskeletal changes. Micro-environmental disturbances related to hypoxia-ischemia in the affected cortex are proposed as likely contributing factors for the long-term production of this neurofibrillary degeneration.

    Notizen: Abstract This cross-sectional study describes the dietary pattern seen at recruitment in a large Spanish cohort comprising 41,451 people (aged 30–69 years) according to high blood-pressure status. We provide information on adjusted mean daily intake of foods and nutrients, by means of a dietary history, from those people self-reported as having high blood pressure as well as from those self-reported as normotensive but having, after actual blood-pressure measurement, systolic or diastolic blood pressures of ≥ 160/95 mmHg. Although with small differences in mean intake people who self-reported high blood pressure have a higher consumption of potatoes, vegetables, vitamin C and E; furthermore, men reported an increased intake of fruit, meat, fish, proteins, dietary fibre, β-carotene and alcohol, and women tended to consume less alcohol, lipids and cholesterol but more proteins, carbohydrates and dietary fibre. Almost no differences are found in fatty acid intake. This pattern is reversed among those self-reported as normotensive but with high blood pressure after actual measurement. We conclude that in this large prospective cohort, awareness or not of having high blood pressure at recruitment is associated with a differential dietary pattern.
