C-reactive protein and efficacy of antiplatelet therapy in (intracranial) atherosclerosis

2018

C-reactive protein (CRP) and other inflammatory biomarkers can indicate both the severity and extent of atherosclerosis, reflecting the inflammatory nature of the disease process.1 Atherogenesis begins with an inflammatory response to vascular injury with cells and mediators initiating the healing response and later inducing growth of atherosclerotic plaques. Inflammation then increases plaque instability, promoting rupture, fissuring, or erosion—the pathogenetic milieu of thrombosis in atherothrombotic ischemic strokes.

121st ENMC International Workshop on Desmin and Protein Aggregate Myopathies. 7–9 November 2003, Naarden, The Netherlands

2004

The 121st European Neuromuscular Centre (ENMC)sponsored International Workshop on ‘DESMIN and Protein Aggregate Myopathies’, attended by 16 active participants from France, Germany, Poland, Spain, Sweden, the United Kingdom and the USA, was actually the fourth one in a row addressing the pathology of the muscle fibre intermediate filament desmin, its associated and similar diseases, all four [1–3] organized by Michel Fardeau and Hans H. Goebel. In his introduction, the chairman, Hans H. Goebel (Mainz), recorded the evolution of ‘Protein Aggregate Myopathies (PAM)’ which are marked by the accumulation of diverse proteins within muscle fibres as a morphologic hallmark in separate myopathies w…

Perineural pattern of aggregation of cellular blue nevus: probable histoarchitectural reminiscence of histogenesis.

2008

A striking feature of cellular blue nevus consists in the presence, in its histologic picture, of numerous hypertrophic nerves and nerve-like figures, positive for histochemical and immunohistochemical methods for nerve fibers and myelin sheaths. These findings, first described in Masson's original article and repeatedly highlighted in the past for their possible histogenetic significance, are currently considered as merely coincidental. However, the thin conventional histologic sections, catching only short tracts of the nerves, preclude a correct observation of their route and do not allow us to verify if there is an architectural relationship between them and the nevus as a whole. With t…

Hemorheologic profile of hyperlipidemic patients treated with gemfibrozil

1996

Abstract We measured the plasma lipid levels and the macrorheologic (whole-blood, plasma, and serum viscosity levels; fibrinogen; hematocrit; mean erythrocyte aggregation; and whole-blood filterability) and microrheologic (erythrocyte membrane fluidity and red cell membrane protein lateral mobility) determinants in a group of 19 hyperlipidemic patients (Fredrickson's classification phenotype IIa, 12 patients; phenotype IV, 4; phenotype IIb, 3) at baseline and after 45 and 90 days of treatment with gemfibrozil (900 mg orally once a day). At baseline we noted statistically significant increases in plasma viscosity level, fibrinogen, and mean erythrocyte aggregation, as well as a statistically…

Occurrence of resveratrol and pterostilbene in age-old darakchasava, an ayurvedic medicine from India

2000

'Darakchasava' is a well known Indian herbal preparation of which the main ingredient is Vitis vinifera L. This 'ayurvedic' medicine is prescribed as a cardiotonic and also given for other disorders. HPLC analysis of this age old formulation revealed the presence of polyphenols like resveratrol and pterostilbene. These phenolic compounds are now known as antioxidants, cancer chemopreventive agents, and also known to reduce mortality from coronary heart disease by increasing high density lipoproteins like cholesterol and inhibiting platelet aggregation (Soleas, J.S., Diamandis, E.P., Goldberg, D.M., 1997. Resveratrol: a molecule whose time has come? and gone? Clin. Biochem. 30 (2), 91-113). …

Two different aggregation principles in reaggregation process of dissociated sponge cells (Geodia cydonium)

1974

Chemisch dissoziierte Zellen des KieselschwammesGeodia cydonium reaggregieren aufgrund zweier verschiedenr Reaggregationsprinzipien. Der Aggnegationsfaktor, auf den die Primaraggregation zuruckgeht, ist membrangebunden und wird durch Proteasen nicht inaktiviert. Der sekundare Aggregationsfaktor wurde 500fach angereichert. Das Molekulargewicht dieses Aggregationsfaktors betragt etwa 20000 Daltons; er ist mit einem ringformigen Makromolekul (2×109 Daltons) assoziiert.

Activation of soluble guanylyl cyclase by YC-1 in aortic smooth muscle but not in ventricular myocardium from rat

1997

1 The effects of YC-1 (3-(5′-hydroxymethyl-2′-furyl)-1-benzyl indazole), an activator of soluble guanylyl cyclase, on tension, levels of cyclic GMP and cyclic AMP, and cardiac L-type Ca2+-current (ICa(L)) were investigated in aortic smooth muscle and ventricular heart muscle from rat. 2 YC-1 (0.1–30 μM) induced a concentration-dependent relaxation in aortic rings precontracted with phenylephrine (3 μM). The relaxant effects of YC-1 were reversed by 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (30 μM; ODQ), potentiated by zaprinast (10 μM) and antagonized by Rp-8-Br-cGMPS (100 μM). 3 In ventricular heart muscle strips, YC-1 (30 μM) exhibited no effects on force of contraction (Fc) in the abse…
