Abstract Objective To identify independent predictors of the risk of recurrent cardiovascular events in patients (pts) with unstable angina (UA) in a conservative treatment strategy. Material and methods The study involved 236 patients with UA with low risk according to GRACE scale and conservative treatment strategy. The end points were: recurrent UA, myocardial infarction (MI), death. The mean age was 60.2±7.3 years. All pts were performed general blood analysis, determination of troponin I, BNP, C-reactive protein, myeloperoxidase, von Willebrand factor, fibrinogen, antithrombin III and also the performance of the thrombin generation test, aggregatogram on aggregometry Multiplate impedance and ECG, EchoCG, Holter ECG. Results Cardiovascular events developed in 104 (44%) pts during 5 years of follow-up, and in the first year of follow - up-in 58 people (24.6%), followed annually by 10–14% of events for the year. MI developed in 21 pts (8.9%), recurrent angina in 75 (31.8%) pts, 51 (21.6%) pts underwent coronary artery stenting, and 26 (11%) pts underwent coronary bypass surgery, 8 (3.4%) patients died. Having studied all the objective data of the observed patients, we concluded that independent predictors of the risk of recurrent cardiovascular events were: previous MI (RR=2,8; 95% CI 1,32–6,08; p=0,0028), type II Diabetes (RR=3,1; 95% CI 1,78- 5,37; p=0,0001), first-time angina pectoris (RR=3,7; 95% CI 2,68–5,85; p=0,001, smoking (RR=2,1; 95% CI 1,21–3,74; p=0,0129), baseline myeloperoxidase >316 pmol/l (RR=3,1; 95% CI 1,29–4,74; p=0,029), high sensitive CRP >3,8 g/l (RR=3,9; 95% CI 2, 44–6,14; p=0,0001), mean platelet volume >9,6fl (RR=2,9; 95% CI 1,49–5,52; p=0,0006), area under the curve ADP- test AUC >60 U (RR=3,4; 95% CI 2, 3–5,2; p=0,002). Conclusions Cardiovascular events developed in 44% of pts over 5 years of follow-up. Independent predictors of adverse outcomes in pts with UA with low risk according to GRACE scale were: previous MI, type II Diabetes mellitus, first-time angina pectoris, smoking, baseline myeloperoxidase levels>316 pmol/l, highly sensitive CRP>3.8 g/l, MPV>9.6fl, and the area under the ADP test curve >60 U.

Radio Event

The type II solar radio bursts produced by a shock wave passing through the solar corona are one of the most frequently studied solar activity phenomena. The scientific interest in this type of phenomenon is due to the fact that the presence of this radio event in a solar flare is an almost certain indicator of a future geophysical effect. The origin of the shock waves which produce these bursts is not at all simple; besides the shocks which are generated as a result of a strong energy release during the impulsive phase of a flare, there are also the shocks generated by a coronal mass ejection or the shocks which appear in the interplanetary space due to the supplementary acceleration of the solar particles.

The Type I simple cold block device was described by Bullivant and Ames in 1966 and represented the product of the first successful effort to simplify the equipment required to do sophisticated freeze-cleave techniques. Bullivant, Weinstein and Someda described the Type II device which is a modification of the Type I device and was developed as a collaborative effort at the Massachusetts General Hospital and the University of Auckland, New Zealand. The modifications reduced specimen contamination and provided controlled specimen warming for heat-etching of fracture faces. We have now tested the Mass. General Hospital version of the Type II device (called the “Type II-MGH device”) on a wide variety of biological specimens and have established temperature and pressure curves for routine heat-etching with the device.

Dogs were injected intravenously with E_. coli endotoxin (2 mg/kg), and lung samples were taken at 15 min., 1 hr. and 24 hrs. At 15 min., occlusion of pulmonary capillaries by degranulating platelets and polymorphonuclear leukocytes (PML) was evident (Fig. 1). Capillary endothelium was intact but endothelial damage in small arteries and arterioles, accompanied by intraalveolar hemorrhage, was frequent (Fig. 2). Sloughing of the surfactant layer from alveolar epithelium was evident (Fig. 1). At 1 hr., platelet-PML plugs were no longer seen in capillaries, the endothelium of which was often vacuolated (Fig. 3). Interstitial edema and destruction of alveolar epithelium were seen, and type II cells had discharged their granules into the alveoli (Fig. 4). At 24 hr. phagocytic PML's were frequent in peripheral alveoli, while centrally, alveoli and vessels were packed with fibrin thrombi and PML's (Fig. 5). In similar dogs rendered thrombocytopenic with anti-platelet serum, lung ultrastructure was similar to that of controls, although PML's were more frequently seen in capillaries in the former (Fig. 6).

Several patients with Fabry's, Gaucher's diseases and hyperlipoproteinemia type II and with arthropatic manifestations were observed.As no histological explanation for these symptoms was available,an ultrastructural study of synovial tissue was done to establish an anatomoclinical relation.Material and Methods :synovial membrane samples were obtained by needle biopsies of the knee from three patients with arthropatic manifestations of each disease.They were fixed in 5% glutaraldehyde, postfixed in 1% osmium tetraoxyde and embedded in Epon 812. Thin sections coloured by uranyl acetate and lead citrate were observed with an Elmiskop I Siemens electron microscope.Two important phenomena were observed in synovial tissue:Specific patterns of each lipid storage disease,which are now well known.In all the three metabolic diseases, hydroxyapatite-like crystals were found. They are characterized by their intramitochondrial localization, without any relation with cristae,an anarchic disposition and a mean size of 550 A.Crystals may be found also free in the cytoplasm of synoviocytes Some micrographs suggest an evolution in four steps :a. mitochondria with only a few microcrystalsb. mitochondria stuffed with these structuresc. disruption of mitochondria membranesd. microcrystals appear free in the cytoplasm

Experimental infection of chimpanzees with non-A, non-B hepatitis (NANB) or with delta agent hepatitis results in the appearance of characteristic cytoplasmic alterations in the hepatocytes. These alterations include spongelike inclusions (Type I), attached convoluted membranes (Type II), tubular structures (Type III), and microtubular aggregates (Type IV) (Fig. 1). Type I, II and III structures are, by association, believed to be derived from endoplasmic reticulum and may be morphogenetically related. Type IV structures are generally observed free in the cytoplasm but sometimes in the vicinity of type III structures. It is not known whether these structures are somehow involved in the replication and/or assembly of the putative NANB virus or whether they are simply nonspecific responses to cellular injury. When treated with uranyl acetate, type I, II and III structures stain intensely as if they might contain nucleic acids. If these structures do correspond to intermediates in the replication of a virus, one might expect them to contain DNA or RNA and the present study was undertaken to explore this possibility.

Grain Size Control

The intermetallic compound Nb3Sn is a type-II superconductor of interest because it has high values of critical current density Jc in high magnetic fields. One method of forming this compound involves diffusion of Sn into Nb foil containing small amounts of Zr and O. In order to maintain high values of Jc, it is important to keep the grain size in the Nb3Sn as small as possible, since the grain boundaries act as flux-pinning sites. It has been known for many years that Zr and O were essential to grain size control in this process. In previous work, we have shown that (a) the Sn is transported to the Nb3Sn/Nb interface by liquid diffusion along grain boundaries; (b) the Zr and O form small ZrO2 particles in the Nb3Sn grains; and (c) many very small Nb3Sn grains nucleate from a single Nb grain at the reaction interface. In this paper we report the results of detailed studies of the Nb3Sn/Nb3Sn, Nb3Sn/Nb, and Nb3Sn/ZrO2 interfaces.
