Comparison of extraction techniques and augers of different size.

Because of differences in winter survival of Pratylenchus penetrans after different host plants, concern arose about traditional extraction and soil sampling techniques. Possible bottlenecks are a too short incubation period of the root material for the time of year, or an auger size to small to pick up tough, fresh, root material. Two experiments were carried out to compare different auger sizes and variations on the standard Oostenbrink elutriation technique with additional filter-incubation of the organic material left on the top sieve (180 microns) of the elutriator.

Host suitability of arable and vegetable crops for Pratylenchus penetrans.

A method was developed to test host suitability for the rootlesion nematode, P. penetrans in pot-experiments. Quarts-sand with transplanted seedlings was inoculated with a suspension of P.

Growth failure in a child showing characteristics of Seckel syndrome: possible effects of IGF-I and endogenous IGFBP-3.

Seckel syndrome is an autosomal-recessive disorder with a frequency of less than 1/10 000 births in which there are multiple malformations including severe short stature. We report on a patient with Seckel syndrome with a current body height of -7.5 SDS.

CD4 T lymphocytes from patients with chronic fatigue syndrome have decreased interferon-gamma production and increased sensitivity to dexamethasone.

A disturbed hypothalamus-pituitary-adrenal gland axis and alterations at the immune system level have been observed in patients with chronic fatigue syndrome (CFS). Glucocorticoids are known to modulate T cell responses; therefore, purified CD4 T cells from CFS patients were studied to determine whether they have an altered sensitivity to dexamethasone (DEX). CD4 T cells from CFS patients produced less interferon-gamma than did cells from controls; by contrast, interleukin-4 production and cell proliferation were comparable.

Lifestyle, fibrinolysis and lipids.

Lifestyle including eating habits, physical training, smoking, drinking alcoholic beverages etc. can to a certain extent maintain or spoil our health. The physiological mechanisms of haemostasis and of lipoprotein metabolism play a role in acute cardiovascular diseases but also in a great number of chronic diseases in which vascular pathology is prominent.
