Relining technique for continuous sac enlargement and modular disconnection secondary to endotension after endovascular aortic aneurysm repair (2014)

Endotension is an unpredictable late complication of endovascular aortic aneurysm repair (EVAR). This case report will discuss the successful treatment of enlarged aneurysmal sac due to endotension using the relining technique. An 81-year-old male complained of nondecreasing huge aneurysm sac. He had undergone EVAR for infrarenal abdominal aortic aneurysm 7 years prior and no endoleak was found through follow-up. Initially computed tomography-guided sac aspiration was tried, but in vain, Relining using the double barrel technique and tubular endograft for modular diconnection, which was unexpectedly found in the original endograft, were performed sucessfully. During follow-up after the relining procedure, the size of aneurysm sac continued to decrease in size. The relining technique is effective mothod for treating endotension.

A Study on Jabber-based Instant Messaging System for Mobile Networks (2008)

With the rapid advancement of wireless network technologies, Mobile Instant Messaging (IM) has become a major application in the telecommunications industry. Firstly, this paper introduces recent research and development efforts in constructing mobile IM systems. Secondly, it advances a new service model and implementation mechanism based on Jabber/XMPP. The communication protocol of our system provides an open, expandable, real-time communication technology that can be used to build a wide range of XML applications. The system can build stable and efficient mobile IM service that covers multimedia content sharing and corresponds with external services conveniently. It can also flexibly respond mobile IM requests. The system uses the newest network technology to supply WAP access and provide Web services. Owing to these features, our design model and implementation mechanism may satisfy rapidly increasing and changing requirements.
Positive screening for primary aldosteronism in blacks and whites with essential hypertension (2000)

We determined the plasma aldosterone concentration (PAC)-to-renin activity (PRA) ratio (ARR) after a 4-week drug free interval in a population-based sample of 329 adults with presumed essential hypertension [107 black women (BW), 42 black men (BM), 72 white women (WW) and 108 white men (WM)]. Blood was obtained in the morning with subjects in the sitting position after a period of ambulation. A positive screening test was defined as an ARR of ≥30 with a PAC ≥20 ng/dL. The overall prevalence of a positive screening test was 14.6%. The prevalence of a positive screening test was higher in BW than in BM (26.2% vs. 11.9%, P = 0.059) and also higher in BW than in WW (26.2% vs. 6.9%, P = 0.001). There were no differences in the prevalences of a positive screening test between WW and WM or between BM and WM. In each race-gender group, PRA was significantly lower, and PAC was significantly higher in the screen positive than in the screen negative subjects (P ≤ 0.05). Systolic blood pressure was higher in screen positive than in screen negative BM, BW, and WM. Within each race-gender group, no differences between screen positive and screen negative subjects were noted in diastolic blood pressure, age, body mass index, or blood sodium, potassium, fasting blood glucose, cholesterol, and triglyceride concentrations. These results indicate a high prevalence of a positive screening test for primary aldosteronism in a population-based sample of adults with presumed essential hypertension, especially among BW.
Quantifying neighbourhood preservation in topographic mappings (1996)

Mappings that preserve neighbourhood relationships are relevant in both practical and biological contexts. It is important to be clear about precisely what preserving neighbourhoods could mean. We give a definition of a &amp;quot;perfectly neighbourhood preserving&amp;quot; map, which we call a topographic homeomorphism, and prove that this has certain desirable properties. When a topographic homeomorphism does not exist (the usual case), many choices are available for quantifying the quality of a map. We introduce a particular measure, C, which has the form of a quadratic assignment problem. We also discuss other measures that have been proposed, some of which are related to C. A comparison of seven measures applied to the same simple mapping problem reveals interesting similarities and differences between the measures, and challenges common intuitions as to what constitutes a &amp;quot;good&amp;quot; map. 1 Introduction Problems of mapping occur frequently both in understanding biological processes and in formulatin...
Antimicrobial Profile of Crude Extracts Calotropis Procera and Centella Asiatica against some Important Pathogens (2012)

To investigate in vitro antimicrobial activity of aerial parts of Calotropis procera and Centella asatica Linn., that have been popularly used as folk medicines. The organic solvent plant extracts are tested on the various microorganisms including bacteria and fungi using agar well diffusion technique. The length of the inhibition zone was measured in millimeters from the edge of the well to the edge of the inhibition zone. C. procera showed significant to moderate activity against (14 mm) Pseudomonas marginalis and (21 mm) Streptococcus mutans with 100 mg/ml DMSO plant drug concentration. The results of (MICs) values are lowest at 66 and highest at 152 mg/ml for C. procera whereas 0 to 155 mg/ml for C. asatica . The extracts were assessed in an effort to validate the potential activity of the medicinal plants against microbes.
Goal-oriented Knowledge Reuse via Curriculum Evolution for Reinforcement Learning-based Adaptation (2022)

Reinforcement learning is a powerful methodology that enables self-adaptive systems to relearn and update their adaptation policy when dealing with unforeseen changes. To update the policy more efficiently, several knowledge reuse approaches have been proposed to speed up relearning. However, the current studies treat and reuse the knowledge integrally, which may result in increased relearning costs if the reused knowledge is inappropriate in the changed situation. Generally, some localized pieces of the knowledge are still appropriate for reuse if they are not related to the changes, while some pieces may become inappropriate for reuse if they are affected by the changes. This paper proposes a goal-oriented curriculum evolution method to realize finer-grained knowledge reuse, combining goal-oriented modeling and curriculum learning. The method is twofold: (1) at design time, we apply goal-oriented modeling to design a curriculum in which an RL problem is decomposed into sub-problems, so that knowledge can be decomposed into several pieces of localized knowledge for sub-problems, and (2) at runtime, we evolve the curriculum to reflect changes (i.e., update the sub-problems related to the changes), so that the affected pieces of knowledge can be locally updated to make them appropriate for reuse in the changed situation. The evaluation based on a cleaning robot shows that the relearning time was shortened, demonstrating the effectiveness of our method.
Investigation of Pd∕Ti∕Al and Ti∕Al Ohmic contact materials on Ga-face and N-face surfaces of n-type GaN (2006)

Pd ∕ Ti ∕ Al and Ti∕Al Ohmic contact materials on Ga-face and N-face surfaces of n-type GaN were investigated by measuring the contact resistivities with respect to annealing temperatures. Pd∕Ti∕Al contact showed good Ohmic property in contrast to Ti∕Al contact on N-face surface of n-type GaN. Cross-sectional transmission electron microscopy results on samples of as-deposited and annealed at 450°C for 30s indicated that Pd played an important role in changing the surface state of N-face surface of n-type GaN and less than 50Å of Pd was required to obtain the best Ohmic contact property.

Recent progress on magnetic nanoparticles for magnetic hyperthermia (2016)

Recent advances in nanomaterials science contributed to develop new micro- and nano-devices as potential diagnostic and therapeutic tools in the field of oncology. The synthesis of superparamagnetic nanoparticles (SPMNPs) has been intensively studied, and the use of these particles in magnetic hyperthermia therapy has demonstrated successes in treatment of cancer. However, some physical limitations have been found to impact the heating efficiency required to kill cancer cells. Moreover, the bio-safety of NPs remains largely unexplored. The primary goals of this review are to summarize the recent progress in the development of magnetic nanoparticles (MNPs) for hyperthermia, and discuss the limitations and advances in the synthesis of these particles. Based on this knowledge, new perspectives on development of new biocompatible and biofunctional nanomaterials for magnetic hyperthermia are discussed.
Comparative properties of envelope-associated arginine-gingipains and lysine-gingipain ofPorphyromonas gingivalis (1998)

Two arginine specific proteinases (Arg-gingipain [RGP-A, RGP-B]) and a lysine specific proteinase (Lys-gingipain [KGP]) were purified from materials of the envelope of Porphyromonas gingivalis solubilized by a detergent by the sequential procedures of ion-exchange chromatography, affinity chromatography, and isoelectric focusing. Each purified enzyme showed a single stained band on SDS-PAGE. The three enzymes were commonly activated by reducing reagents such as mercaptoethanol, dithiothreitol and cysteine. RGP-B was activated markedly by glycyl-glycine and KGP was activated significantly by EDTA. Both RGP-A and RGP-B were inhibited by p-hydroxymercuribenzoate, tosyl-L-lysine chloromethyl ketone (TLCK), N-ethylmaleimide, EDTA, leupeptin, L-trans-epoxy-succinylleucylamido-(4-guanidino)butane and antipain. KGP was inhibited by p-hydroxymercuribenzoate, N-ethylmaleimide and TLCK. The molecular masses of RGP-A and RGP-B were the same (43 kDa), and that of KGP was 48 kDa. The hydrolytic activities of RGPs and KGP to chromogenic synthetic substrates were limited to the compounds with arginine and lysine in the P-1 positions, respectively. When IgG was treated with the three enzymes separately, it was demonstrated that two new fragments of 34 kDa and 15 kDa were generated in each reaction product. Hemoglobin was almost exhaustively digested by RGP-B, but substantial degradation could not be induced by RGP-A or KGP treatment.

The plasmin cascade and matrix metalloproteinases in non-small cell lung cancer (1999)

There are several steps involved in the metastatic spread of cancer from the primary tumour to a secondary remote site. Firstly, the cancer cells have to escape from the primary site and then intravasate into the blood or lymphatic circulation. The cells must survive transportation in the circulation before extravasating at a distant site. These cells then need to establish themselves at the new site before growth and replication can occur to form a metastatic colony. During this time the malignant cell has to avoid destruction by the host immune system. Vital to the growth of both the primary and metastatic disease is the capacity of the tumour to induce breakdown of the extracellular matrix (ECM) and the formation of a blood supply through new blood vessel formation, a process known as angiogenesis. The ECM is a framework of proteins and proteoglycans secreted by and surrounding stromal fibroblasts. It gives structural support to cells and plays a central role in cell adhesion, diVerentiation, proliferation, and migration. The ECM is separated from epithelial cells by a basement membrane which is made up of type IV collagen and creates a scaVold upon which heparan sulphate, laminin, and other components are arranged. 1
New and Enhanced Tools for Civil Military Operations (NET-CMO) (2020)

Civil Military Operations (CMO) associated geospatial modeling is intended to enable increased knowledge of regional stability, assist in Foreign Humanitarian Assistance (FHA), and provide support to Force Health Protection (FHP) operational planning tasks. However, current geoenabled methodologies and technologies are lacking in their overall capacity to support complex mission analysis efforts focused on understanding these important stability factors and mitigating threats to Army soldiers and civilian populations. CMO analysts, planners, and decision-makers do not have a robust capability to both spatially and quantitatively identify Regions of Interest (ROI), which may experience a proliferation in health risks such as vector-borne diseases in areas of future conflict. Additionally, due to this general absence of geoenabled health assessment models and derived end-products, CMO stakeholders are adversely impacted in their Military Decision Making Process (MDMP) capabilities to develop comprehensive area studies and plans such as Course of Action (COA). The NET-CMO project is focused on fostering emerging geoenabling capabilities and technologies to improve military situational awareness for assessment and planning of potential health threat-risk vulnerabilities.
REFORMULATION OF COAL-DERIVED TRANSPORTATION FUELS: SELECTIVE OXIDATION OF CARBON MONOXIDE ON METAL FOAM CATALYSTS (2002)

Several different catalytic reactions must be carried out in order to convert hydrocarbons (or alcohols) into hydrogen for use as a fuel for polyelectrolyte membrane (PEM) fuel cells. Each reaction in the fuel-processing sequence has a different set of characteristics, which influences the type of catalyst support that should be used for that particular reaction. A wide range of supports are being evaluated for the various reactions in the fuel-processing scheme, including porous and non-porous particles, ceramic and metal straight-channel monoliths, and ceramic and metal monolithic foams. These different types of support have distinctly different transport characteristics. The best choice of support for a given reaction will depend on the design constraints for the system, e.g., allowable pressure drop, and on the characteristics of the reaction for which the catalyst is being designed. Three of the most important reaction characteristics are the intrinsic reaction rate, the exothermicity/endothermicity of the reaction, and the nature of the reaction network, e.g., whether more than one reaction takes place and, in the case of multiple reactions, the configuration of the network. Isotopic transient kinetic analysis was used to study the surface intermediates. The preferential oxidation of low concentrations of carbon monoxide in the presence of high concentrations of hydrogen (PROX) is an important final step in most fuel processor designs. Data on the behavior of straight-channel monoliths and foam monolith supports will be presented to illustrate some of the factors involved in choosing a support for this reaction.
Exploring Intramolecular Methyl–Methyl Coupling on a Metal Surface for Edge-Extended Graphene Nanoribbons (2021)

Intramolecular methyl–methyl coupling on Au (111) is explored as a new on-surface protocol for edge extension in graphene nanoribbons (GNRs). Characterized by high-resolution scanning tunneling microscopy, noncontact atomic force microscopy, and Raman spectroscopy, the methyl–methyl coupling is proven to indeed proceed at the armchair edges of the GNRs, forming six-membered rings with sp3- or sp2-hybridized carbons.
Relapse of precursor B-cell acute lymphoblastic leukemia as an isolated central nervous system mass lesion 9 years after initial diagnosis (1996)

Seven years after completion of chemotherapy for acute lymphoblastic leukemia, diagnosed at the age of 5 years, a black female presented with signs of increased intracranial pressure. Neuroimaging showed a large enhancing extra-axial occipital tumor mass. The resection specimen showed morphologic, cytogenetic, and immunophenotypic features consistent with relapse of the primary leukemia. Bone marrow examination was negative for malignancy. The long duration of complete remission followed by the formation of a mass in the central nervous system are highly unusual features of recurrent acute lymphoblastic leukemia.
Practice Parameters for the Treatment of Snoring and Obstructive Sleep Apnea with Oral Appliances: An Update for 2005 (2006)

These practice parameters are an update of the previously published recommendations regarding use of oral appliances in the treatment of snoring and Obstructive Sleep Apnea (OSA). Oral appliances (OAs) are indicated for use in patients with mild to moderate OSA who prefer them to continuous positive airway pressure (CPAP) therapy, or who do not respond to, are not appropriate candidates for, or who fail treatment attempts with CPAP. Until there is higher quality evidence to suggest efficacy, CPAP is indicated whenever possible for patients with severe OSA before considering OAs. Oral appliances should be fitted by qualified dental personnel who are trained and experienced in the overall care of oral health, the temporomandibular joint, dental occlusion and associated oral structures. Follow-up polysomnography or an attended cardiorespiratory (Type 3) sleep study is needed to verify efficacy, and may be needed when symptoms of OSA worsen or recur. Patients with OSA who are treated with oral appliances should return for follow-up office visits with the dental specialist at regular intervals to monitor patient adherence, evaluate device deterioration or maladjustment, and to evaluate the health of the oral structures and integrity of the occlusion. Regular follow up is also needed to assess the patient for signs and symptoms of worsening OSA. Research to define patient characteristics more clearly for OA acceptance, success, and adherence is needed.
Systemic availability of orally administered meperidine (1976)

A comparison of the areas under the plasma concentration-time curves after intravenous and oral administration of meperidine in 4 normal subjects indicated that 48% to 56% of the oral dose avoided "first-pass" metabolism and was systemically available. Similar estimates were obtained by applying the Loo-Riegelman method for calculating drug absorption viz, 47% to 60%. Oral availability predicted from a knowledge of drug clearance (blood) after intravenouration-time curves after oral administration exhibited irregularities and double peaks possibly indicative of the action of meperidine on the gut or a recycling process.
RL-BLH: Learning-Based Battery Control for Cost Savings and Privacy Preservation for Smart Meters (2017)

An emerging solution to privacy issues in smart grids is battery-based load hiding (BLH) that uses a rechargeable battery to decouple the meter readings from user activities. However, existing BLH algorithms have two significant limitations: (1) Most of them focus on flattening high-frequency variation of usage profile only, thereby still revealing a low-frequency shape, (2) Otherwise, they assume to know a statistical model of usage pattern. To overcome these limitations, we propose a new BLH algorithm, named RL-BLH. The RL-BLH hides both low-frequency and high-frequency usage patterns by shaping the meter readings to rectangular pulses. The RL-BLH learns a decision policy for choosing pulse magnitudes on the fly without prior knowledge of usage pattern. The decision policy is designed to charge and discharge the battery in the optimal way to maximize cost savings. We also provide heuristics to shorten learning time and improve cost savings.
