Is <b> <i>Mycoplasma pneumoniae</i> Associated with Vascular Disease? </b> (2000)

Several studies have postulated a link between infectious agents and atherosclerosis (3, 12). Epidemiological and pathological studies have shown an association between Chlamydia pneumoniae and atherosclerosis (3, 12). C. pneumoniae has been detected in vascular tissues and degenerative heart valves (3, 9). It has been suggested that Mycoplasma pneumoniae might also play a role in the development of atherosclerosis (12). Myocarditis, pericarditis, cerebral stroke, and vasculitis have been previously associated with M. pneumoniae infection (1, 4, 5, 11). M. pneumoniae might be seen as a plausible candidate to play a role in the pathogenesis of atherosclerosis, because it has been related to cardiovascular disease and its ability to induce chronic inflammation (12). Taylor-Robinson and Thomas have postulated that there is a need to investigate the presence of M. pneumoniae in vascular tissues, because there is a similarity in epidemiological behavior and antibiotic susceptibility between M. pneumoniae and C. pneumoniae(12). Furthermore, M. fermentans has been detected in 1 of 19 human arterial specimens that were positive forC. pneumoniae (10), and it has been shown thatM. gallisepticum exhibits tropism for arterial tissue in turkeys (2). However, nothing is known about the presence ofM. pneumoniae in human atherosclerotic vascular tissues. Therefore, we investigated the presence of M. pneumoniae in atherectomy specimens and in degenerative heart valve (DHV) specimens.
QTL Mapping and Disease Resistance in Cereals (2000)

DNA markers have been successfully used in plant breeding. One special application is Quantitative Trait Loci (QTL) mapping. Recently QTL mapping has received particular attention for studying disease resistance. The DNA markers have been used to study both monogenic as well as quantitative disease resistance. QTL mapping refines the information about the inheritance of disease resistance generating information such as: genome location of each genetic factor, gene action, gene effect and the direction of effects. So, a breeding program that includes QTL mapping procedures is better oriented, maximizing the chances in favor to overcome a disease via host-plant resistance. The collinearity and genome synteny involving the domesticated grasses facilitate the study and the utilization of QTL mapping related to disease resistance. Combination of traditional approaches with QTL mapping in disease resistance could result in more rapid and precise population improvement. Examples of QTL mapping of disease resistance in cereals (resistance to crown rust in oat, to blast disease in rice, to gray leaf spot in maize and to bacterial leaf streak in barley) are considered.

Heparanase, Hyaluronan, and CD44 in Cancers: A Breast Carcinoma Perspective (2006)

Glycosaminoglycans are major constituents of the cancer cell surface and the tumor stroma. The heparan sulfate degrading enzyme heparanase, hyaluronan, and its receptor CD44 are up-regulated in breast cancer, generating a microenvironment that promotes tumor progression and metastasis. Recent experimental and clinical evidence shows that heparanase, hyaluronan, and CD44 regulate cancer cell proliferation, migration, and invasion, as well as tumor-associated angiogenesis and are correlated with patient survival. These findings suggest that they may be used as prognostic factors and targets for breast cancer treatment.
Spinal Cord Compression in Homozygous Beta-Thalassemia Intermedia (1994)

Symptomatic spinal cord compression caused by an epidural mass of extramedullary hematopoietic tissue in patients with beta-thalassemia is a rare occurrence, that becomes exceptional in childhood and adolescence. The literature is not uniform about the optimal treatment of these patients and different modes of therapy have been proposed so far, including surgical excision or decompressing laminectomy followed by local irradiation and/or hypertransfusional regimens. We report the successful treatment of such a complication in an adolescent with homozygous beta-thalassemia by surgery followed by repeated blood transfusions aimed at maintaining hematocrit at normal levels.
The Use of Imiquimod 5% Cream for the Treatment of Superficial Basal Cell Carcinomas in a Basal Cell Nevus Syndrome Patient (2000)

Imiquimod 5% cream appears to be effective in eradicating superficial nonfacial BCCs. The degree of local inflammatory response may affect the patients' tolerability of treatment and therefore patient compliance.
Long-term follow-up of patients with the antibiotic-sterilized aortic homograft valve inserted freehand in the aortic position. (1987)

A series of 252 isolated aortic homograft valves in 248 patients have been followed for 9 to 16.5 years (mean 10.8). The valves were sterilized in antibiotic solution and stored in a nutrient medium at 4 degrees C and were nonvital. There were 15 in-hospital deaths (6%) and a mortality of 2.7% in patients undergoing an elective first operation. Actuarial survival with the study valve in situ was 57% at 10 years and 38% at 14 years. Only 8.4% of the patients died late from homograft valve failure, chiefly because of failure to refer patients with endocarditis for reoperation or because reoperation was refused in elderly, frail subjects. Incompetence was the sole cause of valve failure and was due either to valve wear or endocarditis. Significant incompetence required reoperation. On actuarial analysis, freedom from significant incompetence for the entire group was 95% at 5 years, 78% at 10 years, and 42% at 14 years. Factors increasing the risk of significant incompetence due to valve wear on multivariate analysis were increasing donor valve age (greater than or equal to 55 years), recipient age (less than 15 years), and an aortic root diameter over 30 mm. Analysis of the patient group that excluded each of these variables (low-risk group), which comprised 61% of the study population, indicated freedom from significant incompetence due to valve wear of 98% at 5 years, 94% at 9 years, and 56% at 13 years.
An Analysis of Radar Echo Systems for the Upper Midwestern United States (1977)

An extensive statistical study was made of the properties of radar echo systems in the upper Midwest region of the United States. Mesoscale groupings of echoes with distance scales 10–100 km and time scales 3–10 h instead of individual echoes were considered in the expectation that the former would be more relevant to deterministic short range prediction models. A total of 203 case histories for 1974 was analyzed. Statistics for the area and duration were determined for the three categories of echo systems: those associated with warm fronts, with cold fronts and with neither. Correlations with the positions of the frontal zones and relationships with upper air winds were also made. Consistent with earlier studies, it was found that the larger echo systems tend to last longer and that the direction of motion was usually somewhat to the right of upper level winds. Results provided many quantitative relationships that would be useful for prediction schemes and for developing models that carry mesoscale precipitation areas as explicit parameters.
Syntheses and properties of photochromic polymers of the mercury thiocarbazonate series (1971)

Abstract Photochromic vinyl polymers of the mercuric thiocarbazonate series were synthesized via the three sequences: (1) synthesis of p ‐(meth)acrylamidophenyl mercuric acetate(II) by the reaction of (meth)acrylyl chloride with p ‐aminophenyl mercuric acetate, followed by polymerization to afford corresponding polymers(III) and subsequent reaction with diphenyl‐ or di‐β‐naphthyl‐thiocarbazone, (2) alternative preparation of III by the reaction of (meth)acrylyl chloride polymers with p ‐aminophenyl mercuric acetate, and (3) reaction of N ‐hydroxymethyl (meth)acrylamide polymers with p ‐amidophenyl mercuric thiocarbazonates. The photochromic behavior of these polymers was investigated to provide data which might indicate the effect of steric conditions on the isomerization of the photochromic components in polymers both under illumination and in dark recovery.
Customary homes to smart homes using Internet of Things (IoT) and mobile application (2017)

With an exponential advancement of automation technology, the future of manual systems are changing into automatic systems for various benefits. Also, internet has become an integral part of one's life where Internet of Things (IoT) is the latest and emerging internet technology that has changed the way one looks at things. Internet of things is developing everyday from small scale machines to large scale machines that can share data and accomplish tasks while individuals are occupied with other activities. The main aim of the paper is to design a smart home automation system using IoT, that is to turn a customary home to a smart home for accessing and controlling devices and appliances remotely using Android based Smart phone app. To be specific, we aim to design a low cost, extensible, flexible wireless smart home automation system using IoT which employs the integration of wireless communication, cloud networking to provide users to control a variety of devices from remote locations by providing an user friendly interface and ease of installation. This paper presents the design of smart home automation framework that utilizes the combination of cloud networking and wireless communication, to remote control various electrical appliances (like lights, fans), to users within their home using a smart phone. The system will automatically control appliances on the basis of sensors' data by constantly monitoring the home environment and storing sensor data onto the cloud. To exhibit the possibility and adequacy of our framework, electrical appliances (like lights, fans) and sensors have been incorporated within the proposed home control system.
Region-selective sharpening of magnetic resonance images (1988)

In many applications requiring a careful inspection of nuclear magnetic resonance images, preprocessing techniques can be used to enhance fine structures and expand the contrast. Nevertheless, due to the large nonstationarity of the bidimensional signal it is unlikely that a single method will perform well on the complete image. Since it is frequently observed that elementary image processing can highlight specific features, the authors propose a data reduction technique corresponding to the optimal combination of different processing results into a composite image which benefits from all elementary information. An adaptive implementation of this approach, based on the subdivision of the original images into rectangular surfaces, is described. The method is used to generate images with enhanced contrast and less noise.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Extended-rtPS Algorithm for VoIP Services in IEEE 802.16 systems (2006)

There are several scheduling algorithms for Voice over IP (VoIP) services in IEEE 802.16 systems, such as unsolicited grant service (UGS), real-time polling service (rtPS), UGS with Activity Detection (UGS-AD), and Lee's algorithm using Grant-Me bit of the generic MAC header. However, these algorithms have some problems of a waste of uplink resources, additional access delay, and MAC overhead for supporting VoIP services with variable data rates and silence suppression. To solve these problems, we propose a novel uplink scheduling algorithm (Extended-rtPS) for the VoIP services in IEEE 802.16 systems. Through the performance analysis and simulation results of resource utilization, VoIP capacity, total throughput, and packet transmission delay, we show that our proposed algorithm can solve the problems of the conventional algorithms, and has the best performance among these algorithms. In addition, with simulation results of packet transmission delay, we prove that our proposed algorithm can support more 74%, 24%, and 9% voice users compared with the UGS, rtPS, and UGS-AD (Lee's) algorithms, respectively.

Effect of silicon’s doses in the cultivation of pea (Pisum sativum L.), to obtain a higher yield, district of Barranca [Efecto de dosis de silicio en el cultivo de arveja (Pisum sativum L.), para obtener mayor rendimiento, distrito de Barranca] (2021)

The objective was to determine the adequate dose of silicon foliar fertilization, to obtain a higher yield in pea crops. Regarding the methodology, the research is applied and experimental; Therefore, the Completely Random Block Design comprised of 4 blocks and 4 treatments was used, which were: T1 = 0, T2 = 0.50 L, T3 = 0.75 L and T4 = 1 L Silicon (Sil Trade) / 200 L of water Applied in four times, it is worth mentioning the chemical ingredient of silicon is orthosilicic acid. The physical characteristics from sowing to harvest were evaluated and the silicon concentrations in leaves were analyzed by treatment. Obtained data were processed by analysis of variance and Duncan. The results determined that T4 stood out in plant height with 89.74 cm, number of pods per plant with 37, weight of pods per plant with 234.43 g, yield with 4444.4 kg/ha and silicon concentration in leaves with 1.75 g/100 g of dry material. It is concluded that there were no silicon effects; that is, it did not statistically influence the physical characteristics. However, T4 with 1 L Silicon (Sil Trade) / 200 L of water increased 8.58% of the yield in relation to T1.
Adenosine receptors in frog sinus venosus: slow inhibitory potentials produced by adenine compounds and acetylcholine. (1979)

1. Membrane potential changes produced by adenosine and adenine nucleotides, acetylcholine, and vagus nerve stimulation were studied by intracellular recording in the sinus venosus of the frog, Rana pipiens. 2. Acetylcholine (ACh) released from the vagus nerve terminals evoked a slow hyperpolarization lasting several seconds in the cells of the sinus. Ionophoretic application of ACh from a micropipette produced a response which is similar in time course and amplitude to that evoked by vagus nerve stimulation. Bath application of ACh caused a steady hyperpolarization in quiescent preparations, or cessation of action potential generation in spontaneously active preparations. 3. Adenosine and adenine nucleotides produced hyperpolarizations when applied by addition to the bath or by ionophoresis from micropipettes. The hyperpolarization produced by ionophoresis of adenine compounds was somewhat slower than that produced by ACh. 4. Adenosine and the adenine nucleotides, 5'-AMP, 3'-AMP, 2'-AMP, and 5'-atp were virtually equipotent in their action. Adenosine was at least 1000-fold more potent than other purine and pyrimidine nucleosides or adenine. Both the ribose and adenine groups were important for agonist activity. 5. The concentrations of agonist required to produce half-maximal responses were estimated from dose--response curves as 3 x 10(-7) M for ACh and 2 x 10(-6) M for ATP. ACh is about 7 times more potent than ATP in producing a hyperpolarization. 6. Adenine compounds act directly upon the cardiac muscle fibres: bath or ionophoretically applied adenine compounds act even when transmitter release from nerve terminals is blocked with high (Mn2+) or when ACh receptors are blocked with atropine. 7. Adenine compounds act on the surface of the muscle fibre membrane. Analogues of adenosine which do not enter the cell are potent agonists of the receptor. An adenyl oligonucleotide too large to enter the cell was 2.6 times more potent per mole than adenosine in producing a hyperpolarization. Drugs such as dipyridamole and 6-(2-hydroxy 5-nitrobenzyl) thioguanosine, which are potent blockers of adenosine transport, potentiate the response of the sinus cells to adenosine. 8. Aminophylline and theophylline are competitive antagonists of adenosine action. The apparent Ki for aminophylline inhibition was 5 microM. 9. The response produced by adenine compounds is partly caused by an increase in the permeability of the membrane to K+. The maximum response to both ACh and adenine nucleotides approached the estimated level of EK or ECl. Replacing extracellular chloride with impermeant isethionate had no effect on responses to ACh or adenine nucleotides. The hyperpolarization was not produced by an activation of an ouabain-sensitive pump since 20 microM-ouabain had little effect on the response to adenosine. 10. The response to vagus nerve stimulation is completely blocked by 50 nM-atropine...

Radiant Energies and Irradiances of Capacitor Discharge Lamps (1961)

The radiant energies per square centimeter of six capacitor discharge lamps, with and without reflectors, were measured by the heating effects they produce in a standard graphite cylinder exposed to the flash. Energies as high as 26 joules cm−2 for a single flash are reported. Irradiances were estimated from oscilloscope intensity-time data, and shown to be as high as 66 kw cm−2. This is at least an order of magnitude greater than the irradiances obtainable in solar and arc image furnaces. The usefulness of capacitor discharge lamps as rapid heat sources is discussed.
Nonlinear Distortion Analysis of Multiport Amplifier (2004)

This paper presents an analysis of nonlinear distortion generated in Multi-Port- Amplifier (MPA) systems that have attracted considerable attention for their potential use in multi-beam mobile satellite communications. The MPA configuration is a special one composed of a power divider, a power combiner and an array of high power amplifiers (HPAs). The HPA nonlinear characteristics degrade the MPA linearity. Intermodulation (IM) products generated by this nonlinearity cause interference with signals and degrade the signal transmission performance. We investigated the dominant third-order IM (IM3) performance of an MPA under HPA nonlinear operations by taking the specific properties of the MPA configuration into account and showed that it was possible to improve the carrier level to a third-order IM (C/IM3) ratio by properly assigning multiple carriers to multiple MPA ports without adding any additional circuits. Based on these results, we proposed an amplifier system immune to IM3 interference and a frequency assignment method effective in improving the C/IM3 ratio in an MPA system. The analysis and our proposed system will help make it possible to construct a power-efficient satellite system with a simple configuration not only for multibeam mobile communications but also for other uses.
Symmetrie and Asymmetrie Nuclear Matter in the Thomas-Fermi Model at Finite Temperatures (1999)

Abstract The properties of warm symmetric and asymmetric nuclear matter are investigated in the frame of the Thomas-Fermi approximation using a recent modern parameterization of the effective nucleon-nucleon interaction of Myers and Świątecki. Special attention is paid to the liquid-gas phase transition, which is of special interest in modern nuclear physics. We have determined the critical temperature, critical density and the so-called flash temperature. Furthermore, the equation of state for cold neutron star matter is calculated.
Post-weaning performance of calves as affected by longstem hay and method feeding (1971)

Three different rations were compared for feeding calves immediately after weaning. Desired is a ration that will reduce weaning stress, produce economical gains, and be easy to feed. The rations are shown in Table 4. Initial weight of the calves was taken at the pasture just before weaning. The calves were transported the same day 8 miles to the Beef Cattle Research Center where they were divided into groups and started on experimental rations.
A study of aspect-based sentiment analysis in social media (2017)

In recent years, diverse social media platforms, such as Facebook, YouTube, Instagram, Snapchat, and Twitter, have rapidly grown in size and influence. Various industries, including the media and advertising industries, have made significant efforts to adapt to building competitive advantages using social media in the marketplace. Therefore, it became imperative for marketing and advertising professionals to better understand the complex behaviors and minds of consumers using data mining techniques, which help to handle massive amounts of social media data. In this research, we analyzed Twitter to discover characteristics of social media. This study is intended to address these topics to build a better understanding of Twitter usages. Even if there are many important theories and frameworks in media studies, we were not able to single out one specific theoretical framework for this study. Therefore, by using the active audience concept, and relying on marketing literature, we chose a grounded theory approach and presented research questions for in-depth understanding of Twitter usage in order to detect any patterns that consumers might show. In addition, we proposed a sentiment analysis method and a lexicon building method using the morphological sentence pattern (MSP) model. These methods aim to observe and summarize people's opinions or emotional states from the social media data. Despite the demands of sentiment analysis methods for analyzing social media data, fundamental challenges remain because user-generated online textual data is unstructured, unlabeled, and noisy. Finally, we proposed a method of extracting movie genre similarity for movie recommendation.
