Infektionen im Zusammenhang mit der Anwendung von Hirudo medicinalis – Zwei Fallberichte und Literaturübersicht (2015)

Medicinal leeches are well-established for promoting venous drainage in transplants/flaps and analgesia in osteoarthritis. Although medicinal leeches are bred and kept under controlled conditions, they are colonised by a genuine species-specific bacterial flora. Therapeutic application of leeches implies skin penetration carrying an a priori risk of infection. We report 2 cases with different indications for medicinal leech therapy. In both cases wound infection occurred in close temporal and spatial correlation or with evidence of a leech-associated germ that could be treated successfully. An unclarified complication rate warrants strict indications for the application of medicinal leeches. Preventive measures are currently tested.
Simulation of the Substrate Temperature Field for Plasma Assisted Chemical Etching (2009)

Abstract Surface figuring using reactive plasma jet machining is a promising technology for the manufacture of optical elements. Due to the pure chemical etching mechanism the material removal rate during plasma jet treatment strongly depends on the workpiece surface temperature, which is influenced by the jet heat flux. This paper presents the basis for an enhanced process simulation by introducing a transient heat transfer model including a moving heat source. A comprehensive method of determination for corresponding model parameters has been developed. It is based on temperature measurements during a well defined etching experiment. The model is able to predict the workpiece surface temperature distribution at any given time.
Attractants for Synanthropic Flies: Area-wide Control of Hippelates collusor with Attractive Baits12 (1974)

The attractant Lursect TM was formulated with sugar-toxicant baits and used for area-wide control of Hippelates collusor (Townsend) in California. Spot treatment with the formulation using 1 lb/20 acres reduced populations to very low levels after 2–3 treatments of an isolated agricultural ranch. Continuous treatment (twice weekly) in late 1970 of several golf courses and adjacent agricultural areas breeding H. collusor yielded rapid decline of populations in 4–6 wk. Seasonal treatment (April–October) of the same area 1 year later produced promising results. Semiweekly treatments of agricultural areas infested with and breeding large numbers of H. collusor markedly lowered the density of females (the only sex attracted to hosts and Lursect). As only older females are attracted, the proportion of teneral females increased in the population subjected to attractant-toxicant formulations. The proportion of inseminated and parous females decreased as the treatments continued. Female to male ratios, as expected, also declined.
Endovascular aneurysm sealing as an alternative for the treatment of failed endovascular aneurysm repair (2020)

The results suggest the safety and the efficiency of EVAS in the treatment of complications following EVAR including type Ia, type IIIa, and type IIIb endoleaks. Further studies on larger cohorts and longer follow-up periods are required to confirm the interest of EVAS in the endovascular management of failed EVAR.
Three-component coupling of aryl iodides, allenes, and aldehydes catalyzed by a Co/Cr-hybrid catalyst (2018)

The cobalt/chromium-catalyzed three-component coupling of aryl iodides, allenes, and aldehydes has been developed to afford multi-substituted homoallylic alcohols in a diastereoselective manner. Control experiments for understanding the reaction mechanism reveal that the cobalt catalyst is involved in the oxidative addition and carbometalation steps in the reaction, whereas the chromium salt generates highly nucleophilic allylchromium intermediates from allylcobalt species, without the loss of stereochemical information, to allow the addition to aldehydes.
Incidental metastatic mediastinal atypical carcinoid in a patient with parathyroid adenoma: a case report (2017)

We describe an incidental finding of atypical carcinoid of the mediastinum in a patient diagnosed as having parathyroid adenoma. Clinical manifestations of neuroendocrine syndromes are challenging. Some tumors cluster in a non-classic description with other common neoplasms. They rarely present in isolation, remain clinically silent, and need aggressive workup with the aid of imaging and histopathology.

[Rare association of a coronary fistula with a fusiform aneurysm of the superior vena cava: diagnosis via transesophageal echocardiography and MRI]. (1995)

A congenital fistula of the left circumflex coronary artery with large aneurysmal sacculations and drainage into the vena cava superior is reported in an asymptomatic black adult female. An indicator dilution curve excluded a significant left-to-right shunt. In addition, the patient had a large fusiform aneurysm of the superior vena cava with maximal extension in the anterior upper mediastinum. Transesophageal Doppler echocardiography and magnetic resonance imaging were complementary diagnostic tools, the first for clearly visualizing coronary anatomy and shunt, the second for accurate imaging of the aneurysmal vena cava superior in the upper mediastinum.
Fully automatic mesh generation for 3‐D domains based upon voxel sets (1994)

Abstract Fully automatic three‐dimensional mesh generation is an essential and increasingly crucial requirement for finite element solution of partial derivative equations. The results of numerical simulation, more precisely the convergence and accuracy of numerical solutions, closely depends on the quality of the underlying mesh. This work introduces a fully automatic finite element mesh algorithm with simplexes (tetrahedra), adapted to complex geometries described by disctete data. This paper is divided in four sections: (a) brief introduction to discrete geometry is given, as well as the basic definition of the domain of interest; (b) description of the voxel approach to tetrahedronization. The tetrahedronization process uses a divide‐and‐conquer method, which provides small elements on the boundary of the domain of interest. Voxels of the domain are subdivided according to an automatic procedure, which preserves the topology. Specific rules were introduced which allow reducing the number of voxel configurations to be treated, and consequently the computation time; (c) presentation of results and performances of the mesh algorithms. The resulting algorithm demonstrates an n log n growth rate with respect to the number of elements; (d) optimization of the mesh generation process at hand of a ‘finite‐octree’ type of explicit controlling space.
Molecular detection of Chlamydia trachomatis and HPV infections in cervical samples with normal and abnormal cytopathological findings (2007)

It has been suggested that Chlamydia trachomatis (CT) and human papillomaviruses (HPV) co-infection could contribute to development of intraepithelial lesions. In this study, HPV and CT-DNA were investigated in 250 cervicovaginal samples of patients from Minas Gerais, Brazil. The cytological analysis revealed that 70% of samples (175) were negative, 5.2% (13) presented atypical squamous or glandular cells of undetermined significance (ASCUS/AGUS), 12.4% (31) presented low-grade squamous intraepithelial lesion (LSIL), 10.8% (27) high-grade squamous intraepithelial lesion (HSIL), and 1.6% (4) invasive carcinoma. HPV-DNA and HPV/CT co-infection was observed in 40% (100/250) and in 5.2% (13/250) of samples, respectively. Among the positive cytological samples, HPV-DNA was detected in 73.3% and CT-DNA in 9.33% and in 13%, if only the HPV positive samples were considered. The highest co-infection rate (15.4%) was observed among ASCUS/AGUS samples. Although a significant association was found for HPV infection and the precursor lesions of cervical cancer, it was not possible to establish a significant association between these lesions and CT or HPV/CT co-infection.
Intracerebral cytokine messenger RNA expression in acquired immunodeficiency syndrome dememtia (1993)

The pathogenesis of the dementia associated with human immunodeficiency virus (HIV) infection is unclear, but has been postulated to be due to indirect effects of HIV infection including the local production of cytokines. To determine which cytokines are produced in the nervous system and to identify any correlations with dementia, cytokine and HIV messenger RNA expression was analyzed by reverse transcriptase-polymerase chain reaction in the brains from 24 HIV-infected patients with and without dementia and 9 HIV-uninfected control subjects. Levels of tumor necrosis factor-alpha messenger RNA were significantly higher and levels of interleukin (IL)-4 messenger RNA were significantly lower in demented compared to nondemented HIV-infected patients. Demented patients also had lower IL-1 beta levels than did nondemented patients. No significant differences were detected in the amounts of leukemia inhibitory factor, IL-6, transforming growth factor-beta 1 and -beta 2, monokine induced by gamma interferon-2 (MIG-2), or interferon-gamma messenger RNAs. IL-10 and IL-2 messenger RNAs were undetectable in all brains examined. Cytokine messenger RNA levels in nondemented HIV-positive patients were similar to those in HIV-negative control subjects. HIV transcripts were more abundant in subcortical white matter than in the basal ganglia, cortex, or deep white matter. Our findings suggest a possible role for tumor necrosis factor-alpha in the development of neurological dysfunction. Increased levels of tumor necrosis factor-alpha messenger RNA were not associated with increased levels of IL-1 beta messenger RNA, suggesting differential regulation of these monokines in acquired immunodeficiency syndrome dementia.(ABSTRACT TRUNCATED AT 250 WORDS)
Liquid Chromatography/Mass Spectrometry Analysis of Biosurfactant Glycolipids Secreted by Microorganisms (2005)

Biosurfactant glycolipids are compounds with a sugar residue linked to a lipid hydrophobic moiety by a glycosidic bond; their structures vary in size, complexity, and function and they are part of the larger family of glycoconjugates. Microorganisms such as yeasts and bacteria can secrete large amounts of simple extracellular glycolipids containing a monoor disaccharide glycosylated to a hydroxy fatty acid (FA) (1). The amphiphilic structure of these products imparts to them surfactant-like properties that make them attractive bioemulsifiers in which there is growing commercial interest (2,3). Although strategies have been developed for their synthesis (4), the natural products secreted by microorganisms are usually preferred for marketing reasons (5). Most of these microorganisms produce a complex mixture of glycolipids and their structural identification requires sophisticated methods of analysis. In this sense, nuclear magnetic resonance (NMR) spectroscopy is usually a good option, but this method of analysis often requires tedious sample purification. Alternatively, mass spectrometry (MS) can provide information on glycolipid structures, especially if it is associated with a chromatographic separation technique. In general, glycolipids have molecular weights that are too large for gas chromatography (GC). The introduction of high performance liquid chromatography (HPLC) associated with mass spectrometry (LC/MS), however, has opened a new dimension in the analysis of glycolipids. Mass spectral characterization using ionization techniques such as electron impact (EI) causes extensive fragmentation of glycolipids, providing little information on molecular size or structural characteristics (6). On the other hand, “soft” ionization techniques such as atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) often permit the identification of pseudomolecular ions and a controlled degree of fragmentation. Using these two ionization methods it is often possible to obtain fine structural information. When used in combination with HPLC, this technique allows further separation and quantification of complex mixtures of glycolipids. In this chapter the discussion will focus on the analysis of simple biosurfactant glycolipids Ch10(LipidAnalysis)(447-471)Co1 2/10/05 2:12 PM Page 447
Fast Approximation of Centrality (2000)

Social studies researchers use graphs to model group activities in social networks. An important property in this context is the centrality of a vertex: the inverse of the average distance to each other vertex. We describe a randomized approximation algorithm for centrality in weighted graphs. For graphs exhibiting the small world phenomenon, our method estimates the centrality of all vertices with high probability within a (1+epsilon) factor in near-linear time.
Comparison of two computer-automated procedures for tinnitus pitch matching. (2002)

Clinical assessment of the perceptual characteristics of tinnitus usually includes an attempt to match the pitch of tinnitus to a pure tone. A standardized clinical protocol for tinnitus pitch matching does not yet exist, and there is a history of unsuccessful attempts to obtain such measures reliably. The present study was designed to evaluate new protocols for identifying the perceived pitch of tinnitus, with the objectives of reducing testing time and improving test-retest reliability. Two protocols ("Octave" and "Binary") were developed, each of which was patterned after the testing procedure previously developed at the Oregon Tinnitus Clinic and used to assess thousands of tinnitus patients. Both protocols use computer-automation to conduct testing; the protocols differ according to their specific testing algorithms. Twenty subjects with nonfluctuating tinnitus were each tested over two sessions. Results of testing revealed that both protocols could obtain pitch matches within 20 to 25 min. Reliability of responses was good for some subjects but not others, and the Binary protocol generally provided more reliable results.
Coherently driven semiconductor quantum dot at a telecommunication wavelength (2008)

We proposed and demonstrate use of optical driving pulses at a telecommunication wavelength for exciton-based quantum gate operation. The exciton in a self-assembled quantum dot is coherently manipulated at 1.3 microm through Rabi oscillation. The telecom-band exciton-qubit system incorporates standard optical fibers and fiber optic devices. The coherent manipulation of the two-level system compatible with flexible and stable fiber network paves the way toward practical optical implementation of quantum information processing devices.
Fabrication of Polycrystal line, Transparent YAG Ceramics by a Solid‐State Reaction Method (1995)

Polycrystalline, transparent YAG (Y 3 AI 5 O 12 ) ceramics were fabricated by a solid‐state reaction method using high‐purity Al 2 O 3 and Y 2 O 3 powders. The mixed powder compacts were sintered at 1600° to 1850°C for 5 h under vacuum. Optical transmittance in the region between the ultraviolet and infrared wavelengths for YAG ceramics (1 mm thick) sintered at 1800°C was similar to that for a YAG single crystal.
Analysis of thermal effects in endoscopic nanocarriers-based photodynamic therapy applied to esophageal diseases (2014)

In this work we propose a predictive model that allows the study of thermal effects produced when the optical radiation interacts with an esophageal or stomach disease with gold nanoparticles embedded. The model takes into account light distribution in the tumor tissue by means of a Monte Carlo method. Mie theory is used to obtain the gold nanoparticles optical properties and the thermal model employed is based on the bio-heat equation. The complete model was applied to two types of tumoral tissue (squamous cell carcinoma located in the esophagus and adenocarcinoma in the stomach) in order to study the thermal effects induced by the inclusion of gold nanoparticles.
Experimental investigation of electrolytically treated and silane grafted carbon fiber-reinforced thermoplastic polyurethane composites (2023)

In this study, the continuous fiber rowing of 12K carbon was electrolytically oxidized by incorporating three different types of electrolytes: Ammonium bicarbonate, Sulfuric acid, and Sodium hydroxide at various concentrations. Upon chemical treatment, the fibers were grafted with 3-Aminopropyl-triethoxysilane (APTS), a silane coupling agent, to achieve better interlocking and compatibility with the thermoplastic polyurethane (TPU) matrix. Mechanical properties were analyzed by tensile tests, morphological analysis was carried out through Scanning Electron Microscopy, and spectral analysis was studied through X-ray photoelectron spectroscopy (XPS) characterizations. The results show that 10% sulfuric acid treatment plus APTS grafted carbon fiber/TPU composites showed an average tensile load capacity of 2528 N, about 39% higher than raw carbon/TPU. The morphological analysis provided compelling evidence for the increase in mechanical properties of modified fiber composites as the interfacial bonding between the electrolytically modified and silane coated fiber/TPU composites was much better than the raw fiber/TPU composites. Further, XPS results confirm that the atomic percentages of Carbon have been reduced, whereas the percentage of oxygen and nitrogen have increased. These compositional changes indicate that the overall interaction between the fiber and the matrix has been enhanced, accounting for improved compatibility between the two interacting phases.
Superconducting Magnet Based VSC Suitable for Interface of Renewable Power Sources (2010)

A novel Direct Current Control (DCC) modular multilevel Voltage-Source Converter (VSC) based on High- Superconducting Magnet Energy Storage (SMES) has been proposed. The design of the conduction-cooled magnet and the current carrying test results are introduced. Compared with the exiting types of converter, the Superconducting Magnet based VSC can be more effective in coping with the unbalanced power between the AC and DC sides, which makes it more suitable for the usage of the interface of the renewable power with the main grid. The concerned parameters of the converter have been deduced. The topology and the control strategy have been verified by a digital model simulated in Matlab Simulink environment.
Advanced Solid Lubricant Films by Ion-Beam Assisted Deposition. (1994)

Abstract : NRL is developing advanced solid lubricating films for bearing assemblies. The films are deposited by ion-beam assisted deposition (IBAD) to thickness that can be controlled from 0.02 micrometers (1 micron inch) to greater than or equal to 1 micrometer (40 microns inch). Unlike evaporated or sputter-deposited films, IBAD films are dense and adhere well to virtually all solid surfaces. Durable films have been deposited on bearing steels, Ti alloys and many ceramic substrates, including Si3N4, alumina, SiC, TiN and CVD diamond. IBAD's multibeam capabilities have also been exploited to produce binary and ternary alloys over a wide range of stoichiometries. Studies of two solid lubricating films, MoS2 and ternary metal oxides, will be highlighted. IBAD MoS2 films exhibit reduced susceptibility to moisture degradation during storage. Alloyed MoS2 films show increased durability in sliding and rolling contact without sacrificing the ultra-low friction behavior of MoS2. For high temperatures, a class of binary metal oxide films are being investigated. Candidate lubricants have been chosen based on tribological behavior of oxide and predictions from thermodynamic phase diagrams. A recent study of the Cu-Mo-O system will be presented.

Minimal degree solutions for the Bezout equation (1987)

We prove two results on the existence of bounds on the (global) degrees of polynomials Xt, solutions to the Bezout equation AtXt + ... + ArXr= C, with At, C, Xi in C[xlt ..., x„]. In the first theorem we require an algebraic hypothesis on the maximum degree homogeneous component of Alt ...,Ar, while the second result holds for all Bezout equations, but r = 2 is needed. Several variations and examples are discussed.
A Thermal Monitoring Sheet With Low Influence From Adjacent Waterbolus for Tissue Surface Thermometry During Clinical Hyperthermia (2008)

This paper presents a complete thermal analysis of a novel conformal surface thermometer design with directional sensitivity for real-time temperature monitoring during hyperthermia treatments of large superficial cancer. The thermal monitoring sheet (TMS) discussed in this paper consists of a 2-D array of fiberoptic sensors embedded between two layers of flexible, low-loss, and thermally conductive printed circuit board (PCB) film. Heat transfer across all interfaces from the tissue surface through multiple layers of insulating dielectrics surrounding the small buried temperature sensor and into an adjacent temperature-regulated water coupling bolus was studied using 3-D thermal simulation software. Theoretical analyses were carried out to identify the most effective differential TMS probe configuration possible with commercially available flexible PCB materials and to compare their thermal responses with omnidirectional probes commonly used in clinical hyperthermia. A TMS sensor design that employs 0.0508-mm Kapton MTB and 0.2032-mm Kapton HN flexible polyimide films is proposed for tissue surface thermometry with low influence from the adjacent waterbolus. Comparison of the thermal simulations with clinical probes indicates the new differential TMS probe design to outperform in terms of both transient response and steady-state accuracy in selectively reading the tissue surface temperature, while decreasing the overall thermal barrier of the probe between the coupling waterbolus and tissue surface.
Darwin: Convolutional Neural Network based Intelligent Health Assistant (2018)

Healthcare is an essential factor for living a good life. Unfortunately, consulting a doctor for non-life threatening problems can be difficult at times due to our busy lives. The aim of healthcare services is to make our lives easier and to improve the quality of life. The concept of personal assistants or chatbots builds on the progressing maturity of areas such as Artificial Intelligence (AI) and Artificial Neural Network (ANN). In this paper, we propose a healthcare assistant that will allow users to check for symptoms of common diseases, a suggestion to visit a doctor if needed, exercise recommendation, tracking exercise/workout routine, along with a comprehensive exercise guide. The primary objective is to develop a system that utilizes AI and deep learning to help improve the lives of people who have busy schedule to easily keep a check on their health.
NeuroVectorizer: end-to-end vectorization with deep reinforcement learning (2020)

One of the key challenges arising when compilers vectorize loops for today’s SIMD-compatible architectures is to decide if vectorization or interleaving is beneficial. Then, the compiler has to determine the number of instructions to pack together and the interleaving level (stride). Compilers are designed today to use fixed-cost models that are based on heuristics to make vectorization decisions on loops. However, these models are unable to capture the data dependency, the computation graph, or the organization of instructions. Alternatively, software engineers often hand-write the vectorization factors of every loop. This, however, places a huge burden on them, since it requires prior experience and significantly increases the development time.
