    Notes: Abstract Background Interureteric ridge edema may be seen at intravenous urography (IVU) and is related to acute lower ureteral obstruction, trauma, or calculi. The purpose of this study was to explore the relationship between interureteric ridge edema and acute distal ureteral obstruction caused by ureteral calculi. Methods A total of 338 patients who had IVU for various indications during a 6-month period were reviewed for the presence of interureteric ridge edema. Results Interureteric ridge edema was seen in 12 (4%) of 338 patients, all with acute lower ureteral obstruction from stones. Interureteric ridge edema was best demonstrated with the partially filled bladder film or postvoid bladder film in all cases. Conclusion Interureteric ridge edema is most commonly caused by stone-induced distal ureteral obstruction and is less commonly seen with recent passage of a stone or other etiologies. Interureteric ridge edema was present in 26% of patients with acute lower ureteral obstruction.

    Notes: Abstract Some 840 bacille Calmette-Guérin (BCG)-vaccinated healthy controls and tuberculosis patients from two Chinese hospitals were submitted to comparative skin tests with purified protein derivative of tuberculin (PPD; as reference) and with the antigen complex A60 from Mycobacterium bovis BCG. In a first trial, including 581 persons (185 healthy juveniles, 180 healthy adults and 216 tuberculosis patients), a limited dose of A60 (1μg) was used. Performance of the A60 test was similar to that of 5 I.U. PPD for controls (cut-off values=5 mm induration diameter), but lower than that seen for tuberculosis patients (10 mm cut-off values). A second survey was conducted on 259 persons (109 recently revaccinated healthy persons, considered as tuberculin-negative in the first trial, and 150 tuberculosis patients), using a higher dose of A60 (2 μg) and the same dose of PPD (5 I.U.). Similar results were obtained with the two tests in all cases, thus supporting the possibility of PPD replacement by A60 in cutaneous testing. The pattern of induration diameter distribution in healthy subjects who took part in the first testing round (64% positively rate) was displaced to the inactivity side (with a peak at 5 to 9-mm diameter), in comparison with the second round (90% positivity rate and peak at 10–14 mm). This indicates a progressive fading of cellular immunity reactions after BCG vaccination. In tuberculosis patients, no correlation was found among the following three parameters: positivity at cutaneous testing (with PPD or A60), titer of anti-A60 mycobacterial immunoglobulins in blood (IgG titer higher than cut-off line) and presence of mycobacteria in sputum.

    Notes: Barley (Steptoe, Crystal and/or Waxbar) was dry milled and fractionated by small scale air classifiers and batch or continuous feed sifters to produce β-glucan-rich fractions. Sieving of barley (all cultivars) yielded lines fractions containing 88–90% starch and a final coarse enriched fraction containing 40–45% total dietary fiber including 16–19%β-glucans and up to 82 μg/g total tocols. The enriched fraction was 20–25% (by wt) of the dehulled barley. The highest β-glucan content by air classification was 9% due to ineffective separation of fines (particles 〈45 μm). Dry fractionation of barley produced a value added enriched product enhanced in factors (ie. tocols, dietary fiber, β-glucans) which slow oxidation, lower cholesterol, moderate glycemic response and which provide unique functional properties in food systems.

    Room-temperature midwavelength two-color infrared detectors with HgCdTe/CdTe multilayer structures by metal-organic chemical-vapor deposition (1995)

    Notes: Two-color photoconductive detectors in the 3–5 μm wavelength range using multilayer undoped n-type Hg1−xCdxTe heterostructures have been demonstrated at room temperature. These heterostructures, consisting of three or four Hg1−xCdxTe layers separated with CdTe layers, were grown by the metal-organic chemical-vapor-deposition (MOCVD) technique. The quality of MOCVD films was verified by near-theoretical values of the minority-carrier lifetime at 300 K, ranging from 0.8 to 4.7 μs depending on the x value. The Hg1−xCdxTe layers are either detectors or filters, and the CdTe layers serve as insulating separators. The concept of using the exponential absorption tails of two Hg1−xCdxTe layers with different band gaps to form an absorption band was verified by the difference in the photoconductive spectral responses between backside and frontside illumination. Two different multilayer heterostructures with two-color peaks at 3.2/3.8 μm and 3.7/4.6 μm, respectively, were studied. © 1995 American Institute of Physics.

    Notes: An arsenic source, tris-dimethylaminoarsine (TDMAAs), was used as a p-type dopant for Hg1−xCdxTe prepared by metalorganic chemical vapor deposition (MOCVD). The Hg1−xCdxTe layers were grown using the interdiffused multilayer process (IMP) at 360 °C with dimethylcadmium, di-isopropyltelluride and elemental mercury. Hole concentrations at 77 K in the range of 2×10+16–7×10+17 cm−3 were obtained in Hg1−xCdxTe with x=0.2–0.35, and ∼30%–50% of the arsenic was electrically active based on the data from secondary ion mass spectrometry (SIMS) measurements. These MOCVD Hg1−xCdxTe layers show minority carrier lifetimes at 77 K in the range of 3 ns–4 μs, which compare favorably with those from the best arsenic-doped Hg1−xCdxTe films prepared by liquid phase epitaxy. © 1995 American Institute of Physics.

    A new concept for coal water mixture stabilization using a polyelectrolyte (1995)

    Notes: Abstract The stabilization mechanism of Sodium Polystyrene Sulphonate (PSSNa) on coal water mixture (CWM) has been examined using the following colloid chemical concept. It is realized that the stabilization of the CWM is due to an increase in electrostatic repulsion between the coal particles and the electrostatic repulsion is influenced strongly by the concentration of metal cations, especially Ca2+ eluted from the coal surface. The adsorption isotherm of PSSNa on the coal surface indicates a weak affinity type and the desorption amount of PSSNa is tremendously small in compared with the amount of adsorption. This indicates that a lot of PSSNa adsorbed weakly has been eliminated from the surface in the pre-washing process of desorption experiment. Furthermore, it appears that the ζ-potential determined by the Acoustosizer for concentrated coal suspension shows higher values than the values determined by the usual electrophoresis, and that the high values hold for a wide range of salt concentrations in the medium. All these results indicate that much PSSNa is adsorbed weakly on the coal surface and the component plays a role in the stability character of CWM, where a large contribution of depletion stabilization effect can be expected.

    Peptide growth factors in normal and hypertrophied bladder (1995)

    Notes: Summary The bladder is a dynamic organ that responds to the stress of outlet obstruction by rapidly increasing in mass and cellular content to compensate for increased urethral resistance. If the outlet obstruction is released prior to decompensation, the hypertrophied bladder will shrink, returning to normal size and cellularity. However, with chronic obstruction the bladder will continue to increase in mass, developing drastic alterations in the amount and composition of the extracellular matrix and, ultimately, losing the ability to function. The extensive tissue remodeling associated with each of these changes requires different bladder components to undergo cellular proliferation, cellular hypertrophy, and even programmed cell death (apoptosis). Each of these cellular processes is known to be regulated by various peptides that are referred to as growth factors. Herein we provide an overview of the growth factors that are known to influence the bladder in addition to a variety of experimental animal studies that putatively identify a role of four particular growth factors [basic fibroblast growth factor (bFGF), transforming growth factor-β (TGF-β), nerve growth factor (NGF), and epidermal growth factor (EGF)] in the obstructive bladder response.

    Notes: Abstract Since the advent of laparoscopy, the sweeping changes seen in general surgery have not been paralleled in vascular surgery. There have been case reports of laparoscopic-assisted aortobifemoral bypass for occlusive disease. Because aneurysmal disease comprises the majority of aortic surgery, we pursued animal and cadaveric feasibility studies for laparoscopic-assisted abdominal aortic aneurysm (AAA) repair. We present a case report of the first clinical case performed under Institutional Review Board protocol using this technique. The patient was a 62-year-old male with a 6-cm infrarenal AAA. After obtaining a pneumoperitoneum, a modified fish retractor was used to exclude the bowel. Ten 11-mm ports provided access to laparoscopically dissect the neck of the aneurysm and the iliac vessels. Then, a 10-cm minilaparotomy was performed and standard vascular clamps were inserted via the port incisions. Standard aneurysmorraphy was performed with a polytetrafluoroethylene (PTFE) tube graft. Laparoscopy conferred three major benefits: better visualization of the aneurysm neck, less bowel manipulation, and avoidance of hypothermia. This case report illustrates the feasibility of laparoscopic-assisted aneurysm repair. Controlled human studies will define the role of laparoscopy in AAA surgery.

    Notes: Summary Three screening methods were used to isolate GL-7-ACA acylase-producing strains. Three positive isolates were identified with Pseudomonas nitroreducens CCRC 11041 possessing the highest activity, against GL-7-ACA and GL-7-ADCA. No activity was detected when Ceph C or succinyl-7-ACA was used as substrate; glutaric acid was found to be inhibitory. CCRC 11041 could produce maximal GL-7-ACA acylase activity when cultivated on meat extract medium II. The enzyme had a pH optimum of 5.0 and a temperature optimum of 42°C.
