Accuracy of routine ultrasonography in screening heart disease prenatally (1997)

The aim of the present study was to assess the accuracy of the four-chamber view as a screening test for detection of congenital heart disease (CHD) prenatally in a low-risk population. A prospective observational study was conducted in 17 ultrasound units of the Piemonte Region, Italy, in pregnancies with no risk factors for CHD. At each routine scan, from 18 weeks of gestational age, the four-chamber view of the heart was looked for. When an anomaly was suspected, the patients were referred to a specialized unit. Follow-up of the babies until discharge from the hospital was obtained. 11 232 sonograms were performed on 8299 pregnancies. Cardiac malformations were diagnosed in 40 newborns (4·8/1000). Six of them (15 per cent) had been recognized in utero. The sensitivity, specificity, and positive and negative predictive values were 15, 99·9, 50, and 99·6 per cent, respectively. When malformations that are not associated with an abnormal four-chamber view were excluded from the analysis, the sensitivity increased to 35·3 per cent. The sensitivity found in this study is low, but it is probably realistic since it is comparable to that reported in other multicentric studies. This type of study should reflect the state of the art of the method applied in the field. Although the sensitivity is low, it would be nil if the test were not performed. Moreover, it will probably increase with better training of the operators and by extending the examination to the ventriculo-arterial connections. © 1997 John Wiley & Sons, Ltd.
Comparative study of chemically synthesized and exfoliated multilayer MoS2 field-effect transistors (2013)

We report the realization of field-effect transistors (FETs) made with chemically synthesized multilayer 2D crystal semiconductor MoS2. Electrical properties such as the FET mobility, subthreshold swing, on/off ratio, and contact resistance of chemically synthesized (s-) MoS2 are indistinguishable from that of mechanically exfoliated (x-) MoS2, however, flat-band voltages are different, possibly due to polar chemical residues originating in the transfer process. Electron diffraction studies and Raman spectroscopy show the structural similarity of s-MoS2 to x-MoS2. This initial report on the behavior and properties of s-MoS2 illustrates the feasibility of electronic devices using synthetic layered 2D crystal semiconductors.
Genetic basis of hypertension (1994)

Recent advances in the genetics of hypertension include studies on localizations of many loci involved in blood pressure regulation in the rat, elucidation of the molecular mechanisms underlying monogenetic forms of hypertension, and studies of candidate genes in primary hypertension. Evidence that the angiotensinogen gene is involved in primary hypertension has been found by linkage in affected sibling pairs, and by the demonstration of increased risk of disease associated with DNA variants of the gene. Similar evidence of linkage and association has been found in preeclampsia, which suggests that the two diseases share at least one common factor of genetic susceptibility.

Effect of Treatment of Mice with Sera Containing Gamma Interferon on the Course of Infection with <i>Salmonella typhimurium</i> Strain LT-2 (1980)

Swiss/Webster mice pre-treated with gamma interferon preparations and then infected with Salmonella typhimurium showed significantly increased survival when compared to mock interferon-treated or control mice. Nude mice similarly pre-treated with gamma interferon showed similar increased survival after S. typhimurium infections. If gamma interferon treatment were delayed until the commencement of the S. typhimurium infection, no effect on mortality was observed. The increased survival of the gamma interferon-treated mice did not appear to be due to increased antibody production, more rapid clearing of bacteria from the circulation, or enhanced uptake of bacteria by phagocytic cells of the spleen, liver, or lungs. The number of viable bacteria isolated from the spleens and livers of interferon-treated mice was significantly lower over time than in organs of mock interferon-treated or untreated mice, suggesting the gamma interferon treatment may have resulted in more efficient killing of bacteria by phagocytic cells.
External condition removal in bearing diagnostics through EMD and One-Class SVM (2012)

The removal of the running conditions influencing data acquisitions in rotating machinery is a very important task because it could avoid some misunderstandings when diagnostic techniques are applied. This paper introduces a new parameter that could be able to identify damage in a rotating element of a roller bearing removing the effect of speed and external load. The parameter proposed in this paper is evaluated through Empirical Mode Decomposition (EMD). Our algorithm proposes firstly the decomposition of the acceleration vibration signals into a finite number of Intrinsic Mode Functions (IMFs) and then the evaluation of the energy for each one of these. Data are acquired both for a healthy bearing and for one with a 450 μm large indentation on a rolling element. Three different speeds and three radial loads are monitored for both cases, so nine conditions can be evaluated for each type of bearing overall. The parameters obtained, namely energy evaluated for a certain number of IMFs, are then used to train a One-Class Support Vector Machine (OCSVM). Healthy data belonging to the nine different conditions are taken into account and OCSVM is trained while other acquisitions are given to the classifier as test object. Since the real class membership is known, we consider how many errors the labelling produces. We compare these results with those obtained by considering a wavelet decomposition. Energies are evaluated for each level of decomposition and the previous approach is then applied to these parameters
Rapid and Sensitive Detection of the Interaction of Human Papillomavirus Virus‐Like Particles with Yeast Whole Cell RNA Using Biolayer Interferometry (2018)

RNA is a potential contaminant encountered in the production of recombinant yeast products such as proteins and virus-like particles (VLPs) and can be a particular concern when RNA associates with the product of interest. In this study a method to monitor and quantify the interaction of RNA with yeast-expressed human papillomavirus (HPV) VLPs using biolayer interferometry (BLI) is developed. Both biosensors with immobilized VLPs as well as biosensors with immobilized RNA are tested. Two types of recombinantly expressed HPV VLPs are used, Type 18 and Type 11. The data show that yeast whole cell RNA associates with Type 18 but not with Type 11 (maximum binding signal of 0.20 ± 0.02 nm on immobilized VLP probes for Type 18 vs. 0.03 ± 0.01 nm for Type 11). Additionally, the results show that a higher ionic strength weakens the affinity by both decreasing the association rate and increasing the dissociation rate, resulting in the dissociation constant increasing from 0.48 × 10<sup>-9</sup> to 2.1 × 10<sup>-9 </sup> M, with phosphate ions having a greater effect on the reduction of association compared to chloride ions.
Growth-associated shedding of a tumor antigen (CE7) detected by a monoclonal antibody. (1989)

A monoclonal antibody was developed against an antigen, termed CE7, which was highly expressed on the surface of rat fibrosarcoma KMT-17 cells (clone A3) cultured in low serum medium (A3-1% FCS). The CE7 antigen was not detectable on A3 cells cultured in ordinary high serum medium (A3-10% FCS), on in vivo passaged A3 cells, or on parental in vivo KMT-17 cell line. However, immunoelectron microscopy and Western blot analyses indicated that CE7 antigen was produced by these tumor cells in all circumstances but was shed from their surfaces in vesicular form into the surrounding tissue culture medium or ascites, unless low serum concentration prevailed and disappeared from their cell surfaces. We have previously reported that the immunogenicity of A3 cells was increased when the serum concentration was lowered from 10% to 1% and the phenomenon paralleled the CE7 antigen expression on the A3 cells. These results suggest that the CE7 antigen could be a tumor-associated rejection antigen and that the expression of the CE7 antigen on A3-1% FCS cells (which is shed by high serum culture or in vivo transplantation and disappears from the cell surface) may play a role in immunological responses against the tumor cells.

Coronary constriction due to neuropeptide Y: alleviation with cyclooxygenase blockers (1989)

Intra-arterial administration of neuropeptide Y (NPY), a peptide endogenous to sympathetic nerves, increases coronary vascular resistance by 30-40%. To test whether blockade of prostaglandin synthesis altered the severity of the NPY-induced coronary vasoconstriction, dogs (n = 25) were anesthetized and instrumented to record hemodynamic parameters. In control animals (n = 11) paired infusions of NPY (42 nmol/3 min) were given at 0 and 120 min. NPY produced similar increases in coronary resistance by 10 min, 31 +/- 7% (mean +/- SD) with the first dose vs. 32 +/- 12% with the second dose. The increases in resistance were due to an initial decrease in coronary flow (10 +/- 6%) followed by a prolonged increase in aortic pressure (15-20% over 20 min). Each infusion of NPY decreased heart rate (-10 +/- 7%) but did not alter left ventricular dP/dt. The effects of NPY lasted 40-60 min. In a separate group, a cyclooxygenase inhibitor (COI), indomethacin (n = 6) or ibuprofen (n = 8), was given 1 h before the second dose of NPY. The increases in coronary resistance were blunted significantly after cyclooxygenase blockade from a predrug value of 36 +/- 13 to 19 +/- 12%. In these treated animals, the decrease (-12 +/- 6%) in coronary blood flow seen with the first dose of NPY was prevented (4 +/- 14%) during the second dose (P less than 0.05). Of the two drugs, ibuprofen appeared to restore coronary flow more than did indomethacin. Neither drug affected the base line or the NPY-elicited changes in aortic pressure, heart rate, dP/dt, or myocardial oxygen demands.(ABSTRACT TRUNCATED AT 250 WORDS)
Panuveitis responsive to 2-cda: an unusual ocular presentation of hairy cell leukemia (1996)

Systemic involvement in hairy cell leukemia (HCL), has rarely been reported but ocular involvement is extremely uncommon. We report an unusual ocular presentation of HCL due to panuveitis with dramatic improvement following treatment with 2-chlorodeoxyadenosine (2-CdA).
Immunoreactive proteins of Mycobacterium avium subsp. paratuberculosis (2012)

Johne’s disease is a Mycobacterium avium subsp. paratuberculosis (MAP)-caused chronic enteritis of ruminants (bovine paratuberculosis) associated with enormous worldwide economic losses for the dairy products industries. MAP is a slow growing bacterium that can infect ruminants and remain latent for years without development of any clinical signs disease evident symptoms. The actual diagnostic tools are able to diagnose this pathology only after years of infection when a relevant number of other animals has been infected. Spread of this pathology causes economic losses because of reduced milk yield, premature culling and reduced slaughter value1.
Movements and recaptures of fish tagged at the Point Beach Nuclear Plant during 1973 (1973)

Roots of kava (Piper methysticum) plant are used in almost all Pacific Ocean cultures to prepare a drink with sedative, anesthetic and euphoric properties. One of the main active ingredients of the extract are kava lactones. Here, kava root CO2 extract and three kavalactones, DL-kavain, dihydrokavain and yangonin (isolated from whole extract by column chromatography) were tested for their inhibitory action on recombinant homomeric human α1 glycine receptors expressed in HEK293 cells. Kava CO2 root extract, as well as the individual components DL-kavain, dihydrokavain and yangonin inhibited glycine receptor activity in a dose-dependent manner. DL-kavain was the most potent inhibitor (IC50 = 0.077 ± 0.002 mm), followed by yangonin (IC50 = 0.31 ± 0.04 mm) and dihydrokavain (IC50 = 3.23 ± 0.10 mm) which were 4- and 40-fold less active than DL-kavain, respectively. Application of kava root extract did not reduce maximum currents, but increased EC50 of glycine. Simultaneous application of kava extract and strychnine showed additive inhibition, suggesting that binding of kavalactones and strychnine on the receptor is mutually exclusive. Overall, kavalactones exert a moderate inhibitory effect on the human α1 glycine receptor with DL-kavain being the most potent constituent.
Haemodynamic effects of prenalterol in patients with severe congestive heart failure – NYHA lll–IV (1982)

In 12 patients with severe congestive heart failure due to ischaemic heart disease (n = 6) and due to congestive cardiomyopathy (n = 6) the haemodynamic effects of a new beta 1-agonist, prenalterol, were studied. Left ventricular (LV) function was studied before and 20 min after infusion of 12 mg prenalterol. Heart rate was kept constant by atrial pacing at a rate of 100 min-1 unless intrinsic heart rate exceeded it. As a sign of positive inotropic support, prenalterol enhanced peak rate of LV pressure development (dP/dt) from 1160 +/- 100 mm Hg/s to 1590 +/- 190 mm Hg/s (p less than 0.005). In the mean LV end-diastolic and end-systolic volume determined by cineventriculography and two-dimensional echocardiography decreased. LV stroke work index measured with both methods increased with 4 ml/m and 5 ml/m, respectively (p less than 0.02). LV ejection fraction was improved by 6% and 8% (p less than 0.005). Increase of peak fall of left ventricular pressure (dP/dt) (1050 +/- 60 mm Hg/s to 1270 +/- 100 mm Hg/s, p less than 0.005) and shortening of time constant (T) of pressure fall from 64.5 +/- 5.0 ms to 44.5 +/- 6.0 ms (p less than 0.005) demonstrated the improved LV relaxation. Analysis of LV volume and myocardial compliance revealed decrease of left ventricular stiffness. Thus, LV filling pressure was reduced from 22.1 +/- 4 mm Hg to 14 +/- 3.5 mm Hg (p less than 0.001). Pressure volume analysis showed a significant increase of LV power and work, as well as a slight decrease of wall stress. Our study could demonstrate, even in patients with severe heart failure, a sustained positive inotropic effect of prenalterol leading to an improved left ventricular contractility, relaxation and compliance. LV power and work was enhanced. The increase of oxygen demand seemed to be counterbalanced by an improved perfusion of particularly subendocardial layers indicated by an increased transmyocardial pressure gradient.
Association Between Bleeding Time and Platelet Adherence to Artery Subendothelium (1984)

The efficacy of five different factor VIII-von Willebrand factor (FVIII-VWF) preparations in mediating adherence of blood platelets to damaged vessel walls was tested in an annular perfusion chamber utilizing human arteries and reconstituted blood. FVIII-VWF-purified by Sepharose CL-4B chromatography and von Willebrand factor prepared from this preparation by dissociation with 0.25 M CaCl2 followed by Sepharose CL-6B chromatography were equally effective in mediating platelet adherence as FVIII-VWF in cryoprecipitate and in plasma from normal subjects. A commercial concentrate of FVIII-VWF (Hemofil, Hyland) used for the treatment of haemophiliacs did not mediate platelet adherence at normal levels of FVIII-VWF related properties. A recently developed high-purity FVIII-VWF preparation (Concentrate II) containing multimers of high molecular weight normalized the platelet adherence. Platelet adherence in plasma obtained from two patients with von Willebrand's disease (VWD) was impaired, but plasma samples obtained following treatment with Concentrate II mediated normal platelet adherence. The normalization of platelet adherence paralleled the normalization of the bleeding time. This platelet adherence assay offers an inexpensive and efficient in vitro tool to test the efficacy of FVIII-VWF preparations designed for VWD patients. Preparations such as cryoprecipitate and Concentrate II mediated the platelet adherence and normalized the bleeding time. The commercial preparation did not mediate platelet adherence and had no effect on the bleeding time.
Spiral CT colonography (virtual colonoscopy): Current status and future directions (2002)

Abstract CT colonography is a novel technique which provides a noninvasive examination of the colon for the detection of colorectal polyps. Following the acquisition of CT data within a single breath-hold, 3D images are created which provide an endoscopic visualization of the mucosal surface. The interactive use of 2D multiplanar reformations provide an extraluminal orientation. Edge-enhanced views, which simulate a barium enema, can provide an overview of the colonic anatomy and demarcate the focal findings. Sensitivity per polyp to detect 10 mm and greater lesions has ranged from 50% to 90%, with sensitivity per patient ranging from 80% to 90%. Key technical areas of investigation are computed aided diagnosis, novel 3D visualizations to unfold the colon, and stool tagging with digital stool subtraction. As further validation in more general patient cohorts is achieved, standardization and appropriate implementation will be important. Copyright © 2002 by W.B. Saunders Company
Field emission from screen-printed carbon nanotubes irradiated by tunable ultraviolet laser in different atmospheres (2003)

A tunable ultraviolet (UV) laser was used to irradiate the screen-printed carbon nanotube (CNT) samples in air and in high vacuum. UV laser lights with wavelengths of 349 and 266 nm from a tunable laser were used with average energy densities of 20.3, 10.2, and 2.25 mJ/cm2, respectively, with different irradiation times. The field emission characteristics of the CNT cathodes irradiated in air were drastically improved, whereas those of the samples irradiated in vacuum were slightly improved. Irradiation by a 266 nm laser light resulted in more obvious improvement in the emission characteristics than that by 349 nm. The maximum emission current density at an applied electric field of 6.2 V /μm at an energy density of 20.3 mJ/cm2 increased from 0.006 to 20.15 mA/cm2 after laser irradiation with a wavelength of 266 nn, and the turn-on field decreased from 3.7 to 1.2 V/μm.

Life issues, robustness consequences and reliability challenges for Very Deep Sub Micron technologies (2010)

Reliability and robustness are strongly linked: aging amplifies robustness issues while environmental stress accelerates aging. As Very Deep Sub Micron (VDSM) technologies offer early wear out and intrinsically lower margins, lifetime and EMC become a coupled challenge that underlines the need of a complete and multidisciplinary approach joining EMC, reliability, device characterization and internal testing skills. Trends, proof of evidence and internal testing approach are described in order to emphasize the need of device aging consideration in robustness studies.
