Abstract Lipids, apolipoproteins, and LpAI and LpAI:AII particles were studied in 43 men (mean age 51, SD 7, years) 24 h before their coronary bypass surgery and in 54 control men (mean age 46 SD 9, years). LpAI and LpAI:AII were analyzed by electroimmunodiffusion and by a noncompetitive enzyme-linked immunoassay, respectively. Concentrations of LpAI and LpAI:AII in the bypass patients were significantly lower (P less than 0.001) than those in the controls. Apolipoprotein AI was significantly correlated with LpAI (P less than 0.001) and LpAI:AII (P less than 0.01) in controls, but only with LpAI:AII (P less than 0.001) in bypass patients. Discriminant analysis between controls and patients showed apolipoprotein AI to be the most powerful discriminant factor; the addition of LpAI and LpAI:AII did not improve discriminant power. We conclude that the determination of LpAI and LpAI:AII particles reflects metabolic disorders in patients but does not significantly influence the discrimination of such patients into risk groups.

Objective To study the role of epicardial adipose tissue (EAT) in determination of risk for adverse course of ischemic heart disease (IHD) in patients after myocardial revascularization.Materials and Methods This study included 217 subjects, 182 IHD patients and 35 evaluated individuals without IHD. Percutaneous coronary intervention (PCI) was performed for 104 patients and coronary bypass (CB) was performed for 78 patients. Also echocardiography (EchoCG) and cardiac computed tomography were performed.Results In IHD patients, EAT volume and thickness were greater than in evaluated subjects without IHD. The composite endpoint (CEP) was observed after PCI more frequently than after CB. In IHD patients with an EAT thickness of 8.5 to 10.2 mm measured with EchoCG in the atrioventricular groove, the risk of CEP was 4.3 times higher after myocardial revascularization than with thicker or thinner EAT regardless of the revascularization method.Conclusion An EAT thickness of 8.5 to 10.2 mm in the atrioventricular groove as measured with EchoCG was associated with a risk of adverse IHD course in patients who have underwent myocardial revascularization.

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Sn 1987A

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
