1) A new procedure for serum lipase determinations is presented. It is specific and sensitive. The incubation period is only 1 hour. 2) This method was clinically applied to some patients with acute pancrea titis and was found to be more useful than other commonly performed pancreatic function tests. 3) Serum lipase activity was determined in the patients with liver diseases consisting of acute...

The heating of deep visceral tumors with implanted electrodes and with self-regulating ferromagnetic thermoseeds was inves tigated. Clinical trials on six patients heated with implanted electrodes indicate that good local tumor control can be obtained by application of hyperthermia during a normal course of radio therapy. The heating method was found practical, and neither toxicity nor severe p...

The use of laser l ight sheet f low visual izat ion, fr inge-type laser ve loc imetry, and Dopp ler g loba l ve loc imetry to make f low f ie ld inves t i ga t i ons i s des c r ibed . The complementary nature o f the techniques is demonstrated by using them to examine the vortical flow fields above a 75 o swept delta wing and a YF-17 model in a low speed wind tunnel. The characteristics of the...

Aim: Sudden cardiac death (SCD) due to arrhythmias is a major cause of in elderly patients on hemodialysis (HD). It has been found that prolonged Tp-e interval (Tpe) electrocardiography (ECG) and increased Tpe/QTc ratio are strongly associated with SCD. In this study, we aimed inves¬tigate the effects changes serum electrolyte levels pre- post-HD ECG parameters, particularly Tpe. Methods: The s...

background: to explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in arak city, arak province, iran. materials and methods: one hundred and thirty four pa!ents with breast cancer were inves!gated. abo blood groups were obtained from medical records. mul!variate analyses were performed, including size of tumor, axillary ...

Interest in the presence and nature of trend arises frequently in science, public health, technology, and many other areas. In this ar- ticle we discuss the notion of trend in the context of recurrent event processes. We discuss different frameworks within which one can inves- tigate trend and consider various ways in which trends may be manifest. Tests for trend are discussed in detail and t...

Nijmegen breakage syndrome (NBS), which in the past also has been classified as a variant of ataxia telangiectasia (AT), is characterized by cancer proneness and extreme sensitivity to ionizing radiation. We inves tigated the DNA damage responses of four independent primary NBS fibroblast cell lines. Following a low dose of ionizing radiation, p53 is mostly induced with slower kinetics and show...

$! A summary of the work recently carried out on the morphotropic phase boundary (MPB) of PZT is presented. By means of x-ray powder diffraction on ceramic samples of excellent quality, the MPB has been successfully characterized by changing temperature in a series of closely spaced compositions. As a result, an unexpected monoclinic phase has been found to exist in between the well-known tetra...

In the past decades, magnesium niobate materials have been extensively inves- tigated due to their exceptional dielectric characteristics at microwave fre- quencies and are widely employed in resonators. present research, nanocrystalline MgNb2O6 having an orthorhombic crys- tal structure with P b c n space group was successfully synthesized 1000oC using a chemical route. X-ray diffraction (XRD)...
