[Osler's disease - a disease with a wide variety of clinical manifestations deserving multidisciplinary competence].

Hereditary haemorrhagic telangiectasia (HHT, Osler disease) is an autosomal dominant disease with a prevalence of about 1 in 5 000. The most common symptom is epistaxis in 90 percent of patients, with an average onset at the age of 12 years. Pulmonary arteriovenous malformations are present in 15-35 percent of patients and are associated with embolic complications, such as stroke and cerebral abscesses.

[Spontaneous coronary artery dissection can cause acute coronary syndrome. Unusual condition that requires thoughtful management and more research].

Spontaneous coronary artery dissection (SCAD) is a non-traumatic and non-iatrogenic injury occurring in the vessel wall caused by either a primary intimal dissection or a primary hematoma in the medial layer. SCAD is more common among women than men and accounts for a small minority of acute coronary syndromes. The causes of SCAD are multifactorial.

Nondestructive detection of decay in living trees.

We used a four-point resistivity method to detect wood decay in living trees. A low-frequency alternating current was applied to the stem and the induced voltage measured between two points along the stem. The effective resistivity of the stem was estimated based on stem cross-sectional area.

Difference in mRNA expression and occurrence of plasminogen activator inhibitors in intrauterine decidua of normal and ectopic human pregnancies.

The objective of this study was to elucidate the mechanisms involved in the formation of a functional decidua. The concentrations of plasminogen activators and plasminogen activator inhibitors in intrauterine decidua from normal and ectopic pregnancies were compared. Intrauterine decidua was obtained by curettage from 17 women with ectopic pregnancies and from five women with normal pregnancies.
