Comprehensive immunohistochemical study of mesothelin (MSLN) using different monoclonal antibodies 5B2 and MN-1 in 1562 tumors with evaluation of its prognostic value in malignant pleural mesothelioma (2017)

Mesothelin (MSLN) is a glycophosphatidylinositol (GPI)-linked cell surface protein highly expressed in several types of malignant tumors sometimes in association with increased tumor aggressiveness and poor clinical outcome. In the present study, 1562 tumors were immunohistochemically analyzed for mesothelin expression using two different types of mouse monoclonal antibodies (5B2 and MN-1) to determine the clinical usefulness of mesothelin immunohistochemistry as well as to pinpoint potential targets for future anti-mesothelin therapy. Also, characterization of selected mesothelin-positive tumors was performed by immunohistochemistry and oncogene sequencing. Among the tumors analyzed, the highest frequencies of mesothelin-positivity were detected in ovarian serous carcinoma (90% in 5B2 and 94% in MN-1). Both antibodies showed frequent positivity in pancreatic adenocarcinoma (71% using 5B2 and 87% using MN-1) and malignant pleural mesothelioma (75% using 5B2 and 78% using MN-1). In malignant mesothelioma, overall survival was significantly longer in the cohort of patients with diffuse membranous expression of mesothelin (P < 0.001). Both antibodies showed positive staining in thymic carcinoma (77% in 5B2 and 59% in MN-1), however, no expression was detected in thymoma. No correlation was detected between mesothelin expression and mismatch repair system deficient phenotype or gene mutation (BRAF and RAS) status in gastrointestinal adenocarcinomas. Mesothelin immunohistochemistry may assist the differential diagnosis of thymoma vs. thymic carcinoma as well as prognostication of mesothelioma patients. Our results demonstrate that patients with solid tumors expressing mesothelin could be targeted by anti-mesothelin therapies.

Sol-Gel Process for Making Pt-Ru Fuel-Cell Catalysts (2005)

A sol-gel process has been developed as a superior alternative to a prior process for making platinum-ruthenium alloy catalysts for electro-oxidation of methanol in fuel cells. The starting materials in the prior process are chloride salts of platinum and ruthenium. The process involves multiple steps, is time-consuming, and yields a Pt-Ru product that has relatively low specific surface area and contains some chloride residue. Low specific surface area translates to incomplete utilization of the catalytic activity that might otherwise be available, while chloride residue further reduces catalytic activity (poisons the catalyst). In contrast, the sol-gel process involves fewer steps and less time, does not leave chloride residue, and yields a product of greater specific area and, hence, greater catalytic activity. In this sol-gel process (see figure), the starting materials are platinum(II) acetylacetonate [Pt(C5H7O2)2, also denoted Pt-acac] and ruthenium(III) acetylacetonate [Ru(C5H7O2)3, also denoted Ru-acac]. First, Pt-acac and Ru-acac are dissolved in acetone at the desired concentrations (typically, 0.00338 moles of each salt per 100 mL of acetone) at a temperature of 50 C. A solution of 25 percent tetramethylammonium hydroxide [(CH3)4NOH, also denoted TMAH] in methanol is added to the Pt-acac/Ruacac/ acetone solution to act as a high-molecular-weight hydrolyzing agent. The addition of the TMAH counteracts the undesired tendency of Pt-acac and Ru-acac to precipitate as separate phases during the subsequent evaporation of the solvent, thereby helping to yield a desired homogeneous amorphous gel. The solution is stirred for 10 minutes, then the solvent is evaporated until the solution becomes viscous, eventually transforming into a gel. The viscous gel is dried in air at a temperature of 170 C for about 10 hours. The dried gel is crushed to make a powder that is the immediate precursor of the final catalytic product. The precursor powder is converted to the final product in a controlled-atmosphere heat treatment. Desirably, the final product is a phase-pure (Pt phase only) Pt-Ru powder with a high specific surface area. The conditions of the controlled- atmosphere heat are critical for obtaining the aforementioned desired properties. A typical heat treatment that yields best results for a catalytic alloy of equimolar amounts of Pt and Ru consists of at least two cycles of heating to a temperature of 300 C and holding at 300 C for several hours, all carried out in an atmosphere of 1 percent O2 and 99 percent N2. The resulting powder consists of crystallites with typical linear dimensions of <10 nm. Tests have shown that the powder is highly effective in catalyzing the electro-oxidation of methanol.
Biology of cell surface heparan sulfate proteoglycans. (1987)

The central question in cell biology is how cells detect, interact and respond to extracellular matrix. The cell surface molecules, which mediate this recognition, consist of a lipophilic membrane domain and an ectodomain binding matrix materials. One group of this kind of molecules is the cell surface heparan sulfate proteoglycans (HSPG). This review summarizes recent information obtained on the cell surface PG of mouse mammary epithelial cells. The glycosaminoglycan containing ectodomain of this PG binds with high affinity Type I, III and V collagen fibrils and the C-terminal heparin binding domain of fibronectin. The PG is mobile on the cell surface, but can be immobilised by ligand binding. At the same time the PG associates with cytoskeleton and links the epithelial cytoskeleton to extracellular matrix. Thus the PG can mediate the changes in the matrix into changes in cellular behaviour, often seen during the regulation of cell shape, proliferation and differentiation. The cell surface PG is also released from the cell surface by cleaving the matrix-binding ectodomain from the membrane domain. Because of the binding properties of the ectodomain, this shedding may provide a means by which epithelial cells loosen their association with the matrix and with other cells, e.g., during normal epithelial development and the invasion of carcinomas.
Predicting Genotype × Environment × Management (G × E × M) Interactions for the Design of Crop Improvement Strategies (2022)

Genotype-by-environment-by-management (G × E × M) interactions for crop productivity represent both challenges and opportunities for long-term crop improvement. They need to be understood and harnessed to accelerate crop improvement to improve our chances of achieving the targets for sustainable agriculture and global food security that are required to enable sustainable development ( https://sdgs.un.org/goals ). Experimental efforts have emerged to quantify their importance, study their genetic and ecophysiological bases, and support efforts to exploit nascent opportunities. The large and complex G × E × M factorial limits the scope and feasibility for purely experimental approaches at all stages of crop improvement programs. However, iterative experimental modeling approaches, combined with advances in genomics, enviromics, phenomics, simulation, and prediction methodologies, offer a range of opportunities, covering both genomic prediction for breeding and agronomic prediction for enhancing the realization of on-farm productivity targets and managing risk. There has been limited coordination of breeding and agronomic prediction efforts to date. We consider the different perspectives of each area and advances toward their integration. This aims to bring an “end-to-end” perspective to the development of G × E × M prediction methodology for sustainable crop improvement; from the creation of new genotypes in breeding programs to their use in combination with agronomic management strategies within on-farm production systems. We draw on the historical and current efforts to improve yield productivity of maize ( Zea mays L.) for the US Corn Belt as a source of examples. Extensions to and examples from other crops and geographies are also considered. Opportunities for G × E × M prediction to enable circular agriculture strategies, that balance crop productivity and sustainable resource use, are identified as potential targets for the future.
Stress determination in nickel monosilicide films using x-ray diffraction (2009)

Lattice spacing measurements of the (211)/(202), (020)/(013), and (111)/(102) reflections were used to calculate the residual stresses in a Ni monosilicide film after cooling from its formation temperature. The ability to measure stresses in crystalline materials using x-ray diffraction requires the use of appropriate x-ray elastic constants, which link the measured strain to the stress tensor of the grains that satisfy the diffraction condition. X-ray elastic constants were calculated in the Neerfeld–Hill (NH) limit for a polycrystalline aggregate composed of orthorhombic crystals. The anisotropy in grains that possess orthorhombic elasticity introduces significant variation in the stresses determined among the three sets of reflections. However, the in-plane stress calculated due to thermal expansion mismatch between NiSi and the underlying Si substrate shows a close correspondence to the average of x-ray measurements.

Microscopic Study of a Ligand Induced Electroless Plating Process onto Polymers (2010)

The ligand induced electroless plating (LIEP) process was recently developed and thoroughly demonstrated with one of the most used polymers for plating processes: acrylonitrile-butadiene-styrene (ABS). This generic process is based, thanks to the use of diazonium salts as precursors, on the covalent grafting of a thin layer of poly(acrylic acid) (PAA) acting as ligand for metallic salts onto pristine polymer surfaces. This strategy takes advantage of the PAA ion exchange properties. Indeed, carboxylate groups contained in PAA allow one to complex copper ions which are eventually reduced and used as catalysts of the metallic deposition. Essentially based on ABS, ABS-PC (ABS-polycarbonate) and PA (polyamide) substrates, the present paper focuses on the role of the polymer substrate and the relationships between the macroscopic properties and microscopic characterizations such as infrared (IR), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The adhesion strength of the metallic layer deposited via that LIEP process with the bulk polymer substrates was successfully compared with the adhesion of similar copper films deposited by the usual process based on chromic acid etching and palladium-based seed layer, by measuring the T-peel adhesion strength, and by carrying out the common industrial scotch tape test. Lastly, the electrical properties of the deposited layer were studied thanks to a four-point probe and scanning tunneling microscopy (STM) measurements.
An Asymmetric Synthesis of the BC Ring System of 8-Epitaxoids by Way of Intramolecular Aldol and Successive Stereoselective Methylation Reactions (1996)

Abstract Optically active 1α-allyl-1β,11β-benzylidenedioxy-2α,10β-bis(benzyloxy)-7β,9β-isopropylidenedioxy-8α,12,12-trimethyl-4-methylenebicyclo[6.4.0]dodecane (2)1 which corresponds to BC ring system of 8-epitaxoids was prepared in high yield form ketoaldehyde 8 via intramolecular aldol cyclization and succesive stereoselective methylation reactions. The ketoaldehyde 8 was synthesized from 8-membered ring compound 3 by stereoselective Michael addition using higher-order cuprate.
Parallel fiber-optic SCI links (1996)

Parallel fiber-optic links promise to be a key enabling technology for distributed computing, substantially increasing transmission distance and bandwidth. The drive to include more and more processors and I/O devices in parallel-processor complexes has created a need for box-to-box interconnection links capable of delivering bandwidth comparable to system backplanes. Point-to-point links overcome the speed and cost constraints of shared buses. However, copper-based point-to-point links can reliably carry high-speed data only a limited distance. Parallel fiber-optic links substantially increase transmission distance and surpass copper's bandwidth capability. Our research addresses the integration of parallel fiber-optic data links into system designs that require a high-bandwidth link over moderate distances. To demonstrate the feasibility of using parallel fiber-optic technology as a fundamental building block in large-scale commercial and parallel machines, we constructed a link testbed.
Protection against reactive oxygen species during mouse preimplantation embryo development: Role of EDTA, oxygen tension, catalase, superoxide dismutase and pyruvate (2001)

Oxidative damage due to the production of reactive oxygen species (ROS) is one of a number of culture-induced stresses which may compromise preimplantation embryo development in vitro. Ethylenediaminetetraacetic acid (EDTA), reduced oxygen tension, superoxide dismutase (SOD) and catalase (CAT) offer protection against oxidative stress, but few attempts have been made to determine which of these agents, or which combination, is the most effective. In particular, no systematic investigation of their actions and interactions has been made using a multifactorial experimental design. Murine zygotes were cultured in the presence or absence of 10 miccroM EDTA, SOD (100-7,000 U/ml) and CAT (50-100 U/ml) at atmospheric (20%) and reduced (5%) oxygen tensions. Blastocyst formation and hatching rates (at various time points), and cell numbers were recorded, whilst parallel groups of embryos had their consumption of pyruvate, a hydrogen peroxide scavenger, measured. All parameters interacted significantly and affected blastocyst formation, hatching rate and cell numbers but the effect of EDTA was the most pronounced. There were beneficial effects of 5% O2, CAT and SOD, while 20% O2 had a deleterious effect on development. EDTA improved blastocyst formation and hatching rates but paradoxically led to a reduction in cell number. 5% O2 was the next most significant parameter to enhance embryo development and also increased cell numbers. No differences in pyruvate uptake were apparent between the various treatment groups. The results suggest that embryo culture in EDTA-free medium under 5% O2 provides the most practical and physiological conditions for in vitro murine embryo culture.

Mobile Subscriber Profile DataPrivacy Breach via 4GDiameter Interconnection (2018)

The interconnection network (IPX) connects telecommunication networks with each other on the globe. The IPX network enables features like voice and data roaming with your mobile device while traveling. Designed as a closed network it is now opening and unauthorized entities now misuse the IPX network for their purposes. The majority of the IPX still runs the Signalling System No 7 (SS7) protocol stack, while the more technically advanced operators roll out and deploy Diameter based LTE roaming. SS7 is known to suffer from many attacks. The first attacks using the Diameter protocol appeared. We will show how an attacker can breach the subscriber's privacy by deducting the subscriber profile from the Home Subscriber Service (HSS) and use the obtained information. The subscriber profile contains all key information related to the users'subscription e.g. location, billing information, MSISDN etc. We will close with a recommendation how to prevent such an attack.
Carrier-based PWM-VSI overmodulation strategies: analysis, comparison, and design (1998)

In this paper, the overmodulation region voltage-gain characteristics and waveform quality of carrier-based pulsewidth-modulated (PWM) methods are investigated. Through detailed analytical study, voltage-gain characteristics are extracted independent of carrier frequency. The influence of blanking time and minimum pulsewidth (MPW) control on the inverter gain characteristics are studied and shown to be significant. A comparative evaluation of the modulator characteristics reveals the advantageous high-modulation-range characteristics of discontinuous PWM methods and, in particular, the superior overmodulation performance of a discontinuous PWM method. The modulation methods under consideration are tested on a PWM voltage-source inverter (VSI)-fed induction motor drive in the laboratory, and the theoretical results are verified by experiments. Also, a gain linearization technique is presented and experimentally verified. The results of this study are useful in the design, performance prediction and development of high-performance overmodulation strategies for PWM-VSI drives.

A new approach to end-functionalization of poly(3-hydroxybutyrate)[PHB] is described. Using genetically engineered PHB synthase fused with a 10x-histidine units at its N-terminus, end-functionalized PHB was synthesized and used for the solid surface modification.
Synthesis of High‐Quality Large‐Area Homogenous 1T′ MoTe2 from Chemical Vapor Deposition (2016)

High-quality large-area few-layer 1T' MoTe<sub>2</sub> films with high homogeneity are synthesized by the controlled tellurization of MoO<sub>3</sub> film. The Mo precursor plays a key role in determining the quality and morphology of the 1T' MoTe<sub>2</sub> . Furthermore, the amount of Te strongly influences the phase of the MoTe<sub>2</sub> . The growth method paves the way toward the scalable production of 1T' MoTe<sub>2</sub> -based applications.
Data-Driven Modeling and Control of Complex Dynamical Systems Arising in Renal Anemia Therapy (2021)

This project is based on a mathematical model of erythropoiesis for anemia, which consists of five hyperbolic population equations describing the production of red blood cells under treatment with epoetin-alfa (EPO). Extended dynamic mode decomposition (EDMD) is utilized to approximate the non-linear dynamical systems by linear ones. This allows for efficient and reliable strategies based on a combination of EDMD and model predictive control (MPC), which produces results comparable with the one obtained in past publications for the original model.
Intussusception like lesion after fenestration in aortic type B dissection (2010)

We report on a patient with Marfan syndrome who presented a Stanford type B dissection of the descending thoracic aorta in late pregnancy. After a cesarean section, the patient presented a severe obstruction of the mesenteric superior artery. An endovascular fenestration was performed (balloon and guidewire based fenestration). Computed tomography (CT) angiography revealed an intussusception 'like' image of the abdominal aortic layers as a consequence of the fenestration procedure. Because of aneurismal progression in the abdominal aorta, surgical repair of the abdominal aorta and intussusception material removal was achieved six weeks later. The patient is currently in good condition. We conclude that the intussusception could be induced by a guidewire. This fenestration procedure is not recommended in patients with structural aortic disorders.
Covalent immobilization of nucleic acid probes onto reactive synthetic polymers (1997)

Oligodeoxyribonucleotide (ODN)/polymer conjugates were obtained by covalent immobilization of various nucleic acid sequences to three different polymers. Two of them bore active ester groups for the covalent linkage via the formation of amide bonds and the third one featured aldehyde moieties for immobilization via reductive amination. The factors controlling the conjugation reaction were found to be the reactivities of the polymers and their abilities at forming hydrogen bonds with the ODNs to be tethered. It was found, as well, that the observed aggregation of the grafting reaction products was essentially due to hydrogen bonding with the nucleic bases of the tethered oligonucleotides. © 1997 John Wiley & Sons, Inc.
