Risk factors for clinical failure of peroral endoscopic myotomy in achalasia (2022)

The recent development of per oral endoscopic myotomy (POEM) has been a game changer in the management of patients with achalasia. However, approximately 1 in 10 patients will not experience clinical success. The aim of this mini-review is to describe the current state of knowledge about the risk factors associated with POEM failure for the treatment of achalasia. Suspected risk factors are detailed into pre-, intra-, and post-procedural factors and put into perspective. Pre-procedural factors have been described, such as pre-treatment Eckardt score, previous treatments for achalasia, sigmoid type esophagus, significant esophageal dilatation, non-type II achalasia, young age and long duration of symptoms. An intra-procedural factor, mucosal injury during POEM, has also been associated with POEM failure. The occurrence of post-POEM GERD was identified as a controversial post-procedural factor associated with failure. The presumed mechanisms of POEM failure are incomplete myotomy or ineffective LES disruption, as confirmed by high-resolution manometry. However, when manometry confirms a significant decrease in LES pressure, it is likely that either impaired peristalsis or a morphologic abnormality such as extreme esophageal dilatation or severe tortuosity, which are not treated by POEM, should be suspected. Notably, a recently described adverse effect of POEM is the formation of a pseudo-diverticulum at the site of the myotomy (blown out myotomy). We finally stress the importance of performing a complete workup in case of POEM failure as different mechanisms of POEM failure should lead to different management.
Discrete Single-Photon Quantum Walks With Tunable Decoherence (2010)

We present an intrinsically stable, deterministic implementation of discrete quantum walks with single photons in space. We measure walks with up to 6 steps and explore the quantum-to-classical transition by introducing tunable decoherence.
A comparison of the in vitro fermentation of four feeds by inocula from bovine rumen digesta and equine caecal digesta, using the pressure transducer technique (1996)

It is generally believed that ruminants are better able to degrade highly fibrous feeds than equines. To determine if this is due to differences between the microflora of the rumen and the equine hind-gut, oatfeed (OF), naked oats (NO), soya hulls (SH) and unmolassed sugar beet pulp (SB) were incubated with inocula prepared from bovine rumen digesta or equine caecal digesta. OF, NO, SH, and SB were ground to pass through a 1 mm mesh screen and incubated for 72 hours, at 39Â°C with inocula prepared from either rumen (R) or caecal (C) digesta. Rumen digesta was obtained from three hay-fed, ruminally - fistulated Hereford x Friesian steers, and caecal digesta from three hay-fed, caecally -fistulated, Welsh-cross ponies. Gas production throughout the incubation was measured using the pressure transducer technique (Theodorou et al , 1994). After the incubation, VFA production was measured and residue weights were calculated for each feedstuff.

Direct cytotoxic action of Shiga toxin on human vascular endothelial cells (1988)

To help explain a role of the Shiga toxin family in hemorrhagic colitis and hemolytic-uremic syndrome in humans, it has been hypothesized that these toxins cause direct damage to the vascular endothelium. We now report that Shiga toxin purified from Shigella dysenteriae 1 does indeed have a direct cytotoxic effect on vascular endothelial cells in cultures. Human umbilical vein endothelial cells (HUVEC) in confluent monolayers were reduced 50% by 10(-8) M Shiga toxin after a lag period of 48 to 96 h. In comparison, nonconfluent HUVEC were reduced 50% by 10(-10) M Shiga toxin within a 24-h period. These data suggest that dividing endothelial cells are more sensitive to Shiga toxin than are quiescent cells in confluent monolayers. Both confluent and nonconfluent HUVEC specifically bound 125I-Shiga toxin. However, in response to the toxin, rates of incorporation of [3H]leucine into protein were more severely reduced in nonconfluent cells than in confluent cells. Toxin inhibition of protein synthesis preceded detachment of cells from the substratum. The specific binding of 125I-Shiga toxin to human endothelial cells and the cytotoxic response were both toxin dose dependent and neutralized by anti-Shiga toxin antibody. Heat-denatured Shiga toxin was without the cytotoxic effect. In addition, the complete culture system contained less than 0.1 ng of bacterial endotoxin per ml, as measured by the Limulus amoebocyte lysate test.

Alpha-Adrenergic Stimulation of Corticotropin Secretion by a Specific Central Mechanism in Man (1987)

In a double-blind study in normal subjects, methoxamine, a highly selective agonist at alpha-1-adrenoceptors, significantly increased circulating ACTH and cortisol. The stimulant effect of methoxamine on cortisol secretion was dose dependent in the range 3.5-7 micrograms/kg/min, was abolished by concomitant administration of the strong alpha-1-adrenergic (and weak H1) antagonist thymoxamine but unaffected by the antihistamine, chlorpheniramine. In order to test whether the action of methoxamine on ACTH secretion was exerted centrally or peripherally, the effects of norepinephrine (NE), an alpha-1-agonist that does not cross the blood-brain barrier, were studied. Doses of NE (1-12 micrograms/min) that increased systolic blood pressure by amounts similar to the changes produced by methoxamine, did not result in any rise in plasma cortisol in normal subjects. The effect of methoxamine, which is more lipid soluble than NE, on plasma ACTH and cortisol, appears to be exerted on the CNS and not at the pituitary or via nonspecific peripheral mechanisms. In addition to its water solubility, NE differs from methoxamine in its beta-1-, beta-2- and alpha-2-agonist actions. However, prenalterol (2 mg) and salbutamol (250 micrograms), respectively beta-1- and beta-2-adrenergic agonist drugs, had no effect on the secretion of ACTH or cortisol and the alpha-2-antagonist yohimbine in an effective dose did not unmask a stimulant effect of intravenous NE on plasma cortisol. At high infusion rates, NE significantly inhibited cortisol secretion. Stimulation of central alpha-1-adrenergic mechanisms results in secretion of ACTH in man, presumably by increased release of a corticotropin-releasing factor.
Prepose: Privacy, Security, and Reliability for Gesture-Based Programming (2017)

With the rise of sensors such as Microsoft Kinect, gesture-based interfaces have become practical. However, to recognize such gestures, applications need access to users' depth and video, exposing sensitive data about individuals and their environment. Prepose, a domain-specific language for building gesture recognizers, combined with a system architecture that protects privacy, security, and reliability with untrusted applications, addresses these threats.
Memory heat map (2015)

In this paper, we introduce a novel mechanism that identifies abnormal system-wide behaviors using the predictable nature of real-time embedded applications. We introduce Memory Heat Map (MHM) to characterize the memory behavior of the operating system. Our machine learning algorithms automatically (a) summarize the information contained in the MHMs and then (b) detect deviations from the normal memory behavior patterns. These methods are implemented on top of a multicore processor architecture to aid in the process of monitoring and detection. The techniques are evaluated using multiple attack scenarios including kernel rootkits and shellcode. To the best of our knowledge, this is the first work that uses aggregated memory behavior for detecting system anomalies especially the concept of memory heat maps.
Theory of electrophoretic separations. Part II: Construction of a numerical simulation scheme and its applications (1986)

Abstract The mathematical model outlined in Part I is recast in a form suitable for numerical computation. The spatial derivatives are replaced by finite‐difference expressions, which leads to a set of ordinary differential equations coupled to a set of nonlinear algebraic relations. This system is solved using existing integration techniques. The resulting algorithm simulates the characteristic behavior of the classical modes of electrophoresis, which is shown by examples involving moving boundary electrophoresis and isoelectric focusing. In the first example two different integration schemes are used and their accuracy and stability investigated. The second example illustrates the versatility of the methodology.
Stabilization of Platinum Oxygen-Reduction Electrocatalysts Using Gold Clusters (2007)

We demonstrated that platinum (Pt) oxygen-reduction fuel-cell electrocatalysts can be stabilized against dissolution under potential cycling regimes (a continuing problem in vehicle applications) by modifying Pt nanoparticles with gold (Au) clusters. This behavior was observed under the oxidizing conditions of the O2 reduction reaction and potential cycling between 0.6 and 1.1 volts in over 30,000 cycles. There were insignificant changes in the activity and surface area of Au-modified Pt over the course of cycling, in contrast to sizable losses observed with the pure Pt catalyst under the same conditions. In situ x-ray absorption near-edge spectroscopy and voltammetry data suggest that the Au clusters confer stability by raising the Pt oxidation potential.
Mass Spectrometric Identification of SARS-CoV-2 Proteins from Gargle Solution Samples of COVID-19 Patients (2020)

Mass spectrometry (MS) can deliver valuable diagnostic data that complement genomic information and allow us to increase our current knowledge of the COVID-19 disease caused by the SARS-CoV-2 virus. We developed a simple, MS-based method to specifically detect SARS-CoV-2 proteins from gargle solution samples of COVID-19 patients. The protocol consists of an acetone precipitation and tryptic digestion of proteins contained within the gargle solution, followed by a targeted MS analysis. Our methodology identifies unique peptides originating from SARS-CoV-2 nucleoprotein. Building on these promising initial results, faster MS protocols can now be developed as routine diagnostic tools for COVID-19 patients. Data are available via ProteomeXchange with identifier PXD019423.
Impact of intensified therapy on clinical outcome in infants and children with neuroblastoma: the St Jude Children's Research Hospital experience, 1962 to 1988. (1991)

To gauge the impact of intensified therapy on the survival of infants (younger than 1 year, n = 129) and children (greater than or equal to 1 year of age, n = 275) with neuroblastoma, we analyzed the results of eight successive clinical trials comparing various combinations of antineoplastic drugs, surgery, and radiotherapy. Changes in treatment did not affect the survival of children with involved noncontiguous lymph nodes or distant metastatic disease until the combination of cisplatin and teniposide (CDDP/VM26) was added to a basic regimen of cyclophosphamide and doxorubicin (CTX/DOX). The resulting 4-year survival was 28% +/- 5% (SE) compared with 7% +/- 2% for previous treatments (P less than .001 by the log-rank test). The 4-year survival of infants with metastatic disease was improved by administering CTX/DOX to all patients, reserving CDDP/VM26 for those whose disease was resistant to the former combination: 82% +/- 6% versus 45% +/- 8% in earlier studies; P less than .001. In the subset of infants whose tumors had disseminated to bone or bone marrow at diagnosis, this therapeutic approach increased the probability of long-term survival from 48% +/- 10% to 85% +/- 9% (P = .01). The small group of children over 1 year of age with localized unresectable tumors also fared significantly better with the switch to CTX/DOX chemotherapy (4-year survival, 93% +/- 7% v 42% +/- 13%; P = .02). Multivariate analysis indicated that young age, limited-disease stage, nonadrenal primary site, and intensified treatment were independent predictors of a more favorable outcome. We conclude that substantial advances in the treatment of neuroblastoma have occurred over the past 25 years at this institution. The current overall 4-year survival probability of 57% +/- 4% compares favorably with estimates for most other common solid tumors of childhood.
Carbon thin films with enhanced properties from cathodic arc plasmas. (1998)

In this thesis, the physical, optical and electronic properties of amorphous carbon ( a-C) thin films deposited using a filtered and unfiltered cathodic arcs are investigated. Firstly, the plasma properties of the filtered cathodic vacuum arc (FCVA) have been examined using planar and wire Langmuir probes in order to optimize the plasma throughput around the 90� bend. The knowledge of plasma characteristics is then utilized to understand the properties of highly tetrahedral amorphous carbon ( ta-C) films as a function of the ion energy, deposition temperature and the deposition rate. A model based on the intrinsic thermal effects of the deposition process is developed to explain the discrepancy of the sp3 fraction versus the ion energy in the literature. The possibility of p-type electronic doping of ta-C has also been investigated by the incorporation of B into the ta-C matrix. It was shown for the first time that the incorporation of B in ta-C reduces the compressive stress while maintaining high sp3 bonding. The details of a new form of arc discharge referred to as the 'stationary arc' which allows the deposition of smooth ta-C films without a bulky macroparticle filter are reported. Finally, extraordinary hardness and elastic properties of a new form of carbon arising from interlinking of graphitic nanoparticles are also presented.
Measurement of local effective diffusivity in heterogeneous biofilms (1998)

We have developed a novel technique to measure local effective diffusivity distribution in heterogeneous biofilms. Mobile microelectrodes (tip diameter 10 μm) and the limiting current technique were employed to measure the effective diffusivity of electroactive species introduced to natural and artificial biofilms. We calibrated the microelectrodes in artificial biofilms of known effective diffusivity and known density. In mixed population biofilms, local effective diffusivity varied from one location to another and decreased toward the bottom of the biofilm. We related local effective diffusivity to local biofilm density using an empirical equation. Surface-averaged biomass density depended on liquid flow velocity at which the biofilms were grown. The higher the flow velocity, the denser were the biofilms. Our technique permits fast evaluation of local effective diffusivity and biofilm density in heterogeneous biofilms.
Cholinergic Treatment of Traumatic Brain Injury (2006)

In spite of affecting the life of millions of people, chronic traumatic brain injury (TBI) has not been hitherto treatable with effective pharmacological tools. This review gives a comprehensive summary of the theoretical data supporting the pharmacological manipulation of the cholinergic system in TBI, pointing out the most urgent targets for further studies. The published clinical evidence of cholinergic treatment in TBI is critically reviewed, with emphasis on modern available cholinergic agents. The lessons from these studies are converted to detailed suggestions for further clinical testing. In addition, the treating clinicians are provided with practical advice, based on personal experience of the cholinergic treatment in over 350 TBI patients. It is concluded that cholinergic agents offer several very promising potentials for the treatment of TBI. However, the final breakthrough requires further well-conducted studies and the potential caveats of the treatment have to be acknowledged.

Reduced size planar Log-Periodic Dipole Arrays (LPDAs) using rectangular meander line elements (2008)

Two different designs for planar LPDAs were designed and measured. Both designs showed low return loss and high F/B ratio, accompanied by an acceptable value of gain. A comparison between them showed that the meander design has similar properties to the Euclidean design, while it occupies less space in the antenna system and thus less weight.
A conceptual design method for the general electric vehicle; pp. 3–16 (2008)

The paper discusses conceptual design of mechatronic systems considering a mobile electrical vehicle platform as an application example. A set of design templates are developed and organized into libraries for the use in early stages of the system design. The advantages of retaining usability of component libraries, allowing verification of design alternatives on the conceptual level are demonstrated.
Real-Time Light Field Processing for Autonomous Robotics (2018)

Typical autonomous robotics systems incorporate multiple cameras, LIDAR sensors and sophisticated computing resources. In this paper we present a software framework for utilizing any array of multiple cameras with sufficient field-of-view (FOV) overlap as a light field imaging system. We show that the typical linear arrays that exist on autonomous cars are sufficient to capture stable time resolved light fields even when moving at highway speeds. We elaborate on the potential pitfalls associated with such a technique namely loss of calibration between cameras due to high frequency vibrations and sudden shocks associated with driving over potholes and highlight a method that can compensate for such effects. We demonstrate that the light fields collected by simple linear arrays can be processed in real time for a wide variety of useful applications including occlusion removal, for signal enhancement in featureless images captured in very low light, for reflection removal and for improved visibility in extreme conditions associated with snow and heavy rain.
