Neonatal Exercise and Age‐Related Oxidative Stress of the Rat Cerebral Cortex (2015)

Aging is related to increased oxidative damage, since Harman proposed the “free‐radical theory of aging”. The cerebral tissue is strongly susceptible to oxidative stress (OS). Although, exercise can counteract OS by increasing anti‐oxidative defenses, it is not necessarily clear which factor of the exercise protocol is more critical. Furthermore, neonatal moderate exercise can decrease brain excitability in a long‐lasting manner (Batista‐de‐Oliveira et al 2012), however, the underlying mechanisms are still not clear. Therefore, we evaluated if the effects of neonatal moderate exercise is related to OS in cerebral cortexes of aged rats (585 days of age). At 15 days old, Wistar rats (n=20) were equally distributed in sedentary or exercised. The treadmill exercise was performed according to Batista‐de‐Oliveira et al (Exp Gerontology 47: 452 – 457, 2012). Malondialdehyde was measured as described by Buege & Aust (M Enzymol 52, 302‐310; 1978), Sulfhydryl content by G. Leipnitz et al. (Life Sciences 87 275–280; 2010), GSH levels by Hissin & Hilf (Analytical Biochemistry 74:214‐216; 1976), SOD activity by Misra & Fridovich (JBC 247(10): 3170‐3175), Catalase measured according to Aebi (M Enzymol 105, 121‐126; 1984), and GST by Nascimento et al. (APNM 39:1‐8). Neonatal exercise does not affect antioxidant enzymes in a long‐lasting manner (p > 0.05). Thereby, this exercise changes brain excitability later in life by other mechanism than increasing anti‐oxidative defenses.

Application of Antibody Array Technology in the Analysis of Urinary Cytokine Profiles in Patients with Chronic Kidney Disease (2006)

Antibody array could serve as a fast, high-throughput and sensitive tool for detecting the excretion of urinary cytokines. Our study is the first to provide an important information regarding the utility of antibody array in evaluating the role of cytokines in the initiation and progression of CKD.
Sub-shot-noise microscopy: imaging of faint phase objects with squeezed light (1993)

We propose a scheme that uses spatially multimode squeezed light, generated by means of a traveling-wave optical parametric amplifier, with which a faint phase object can be imaged with sensitivity better than the shot-noise limit.
Stability Conditions for Multidimensional Queueing Systems with Computer Applications (1988)

A fundamental question arising in the analysis of queueing systems is whether a system is stable or unstable. For systems modeled by infinite Markov chains, we may study the ergodicity and nonergodicity of the chains. Foster showed that sufficient conditions for ergodicity are linked with the average drift. However, complications arise when multidimensional Markov chains are analyzed. We present three methods that provide sufficient conditions for ergodicity and nonergodicity of a multidimensional Markov chain. These methods are next applied to two multidimensional queueing systems: buffered contention packet broadcast systems and coupled processor systems.

Anatomy of the insula functional and clinical correlates (1999)

Much information has been acquired on the anatomy and function of the insula over the past two decades. The insula has a dynamic cytoarchitectonic arrangement throughout its length. The anterior insula is comprised of an agranular allocortical area which functionally is part of the paralimbic belt. Its cortical connections are predominantly with other allocortical areas. Sub cortical, limbic, and brain stem connections underscore the anterior insula s role in processing and integrating autonomic and visceral information. The posterior insula is comprised of a granular isocortical area which functionally is linked to somatomotor systems. Its cortical connections are predominantly with other neocortical areas. Insular cortical and sub cortical connections, especially with the thalamus and basal ganglia, underscore the posteriorinsula s role in somatosensory, vestibular, and motor integration. The dysgranular insula lying in between the anterior and posterior insula represents an anatomical and functional transition between these regions. The predominant flow of intra insular projections from anterior to more posterior regions suggests that the posterior insula also serves as an integrative heteromodal association area for information received by all five senses. The insula plays a role in cardiovascular, gastrointestinal, vestibular, olfactory, gustatory, visual, auditory, somatosensory, and motor modulation. It is also felt to play a role in conditioned aversive learning, a ective and motivational components of pain perception, stress induced immunosuppression, mood stability, sleep, and language. Clinical correlation of damage to the insula, and the resultant impairment of the above functions is discussed.
A Time-Based Recommender System Using Implicit Feedback. (2006)

Abstract- Recommender systems provide personalized recommendations on products or services to customers. Collaborative filtering is a widely used method of providing recommendations based on explicit ratings on items from other users. However, in some ecommerce environments such as a mobile environment, it is difficult to collect explicit feedback data; only implicit feedback is available. In this paper, we present a method of building an effective collaborative filtering-based recommender system for an e-commerce environment without explicit feedback data. Our method constructs pseudo rating data from the implicit feedback data. When building the pseudo rating matrix, we incorporate temporal information such as the user’s purchase time and the item’s launch time in order to increase recommendation accuracy. Based on this method, we built a recommender system for a mobile e-commerce environment and conducted several experiments. Empirical results show our collaborative filtering-based recommender system to be significantly more accurate than a pure collaborative filtering system. Our approach can be applied to building collaborative filtering-based recommender systems for any ecommerce environment without explicit feedback. Keywords: E-commerce, recommender system, implicit feedback, temporal information, mobile environment 1

Comparison of Modified Montmorillonite to Salts and Chelates as Carrier for Micronutrients for Plants: II. Supply of Iron<sup>1</sup> (1976)

Abstract Symptoms of iron deficiency appear very frequently in the calcareous soils which represent a major part of the agricultural soils of Israel; therefore a search for novel carriers of iron is constantly conducted. Previous studies showed that Cu, Zn, and Mn, attached to modified montmorillonite, can effectively replace salts and chelates as carriers for micronutrient elements for plants. In this research, the effect of iron attached to montmorillonite clay on element uptake and yield of plants was compared to that of commonly used iron sulphate or EDTA and EDDHA chelates. In the greenhouse, beans ( Phaseolus vulgaris L.) were grown in two calcareous, (Rendzina), iron deficient soils and were treated with either FeSO 4 , Fe +3 ‐EDTA, Fe +3 ‐EDDHA, or Fe +2 bound to montmorillonite clay. The rates of iron added varied from 15 to 60 mg Fe/kg soil for the salt and 3 to 12 mg Fe/kg soil for the chelates and the clay forms. It was found that Fe +3 ‐clay and Fe +3 in chelates, added at equivalent rates, supplied iron in comparable amounts; FeSO 4 , added at the conventional rates which are five to ten times higher than that added as clay‐ and chelate‐bound iron, caused similar or lower uptake and yields. Moreover, the slow release of iron from Fe‐clay, even when supplied in high rates, prevented excessive iron uptake which otherwise, as in the case of the chelate FeEDDHA, interfered with plant development. It is suggested that iron attached to mortmorillonite clay can be used as an efficient source of iron for plants grown in calcareous soils.
Preliminary results of intracranial angioplasty for vascular stenosis caused by atherosclerosis and vasculitis. (1996)

Intracranial percutaneous transluminal angioplasty is a viable nonsurgical option for the treatment of atherosclerotic vascular insufficiency, but it may not be as successful in treating lesions caused by vasculitis in the acute phase.
Testing implications of data dependencies (1979)

Presented is a computation method—the chase —for testing implication of data dependencies by a set of data dependencies. The chase operates on tableaux similar to those of Aho, Sagiv, and Ullman. The chase includes previous tableau computation methods as special cases. By interpreting tableaux alternately as mappings or as templates for relations, it is possible to test implication of join dependencies (including multivalued dependencies) and functional dependencies by a set of dependencies.
Concepts of Reactive Power Control and Voltage Stability Methods in Power System Network (2013)

The intent of this paper is to present an analysis of reactive power control and voltage stability in power systems. It identifies a new model used to enhance voltage stability and exposes several key issues that had remained as research challenges in this area. The steady state voltage and reactive power control in distribution systems can be properly controlled by coordinating the available voltage and reactive power control equipment, such as on-load tap-changers, substation shunt capacitors and feeder shunt capacitors. It began with an overview of reactive power and voltage stability in transmission, distribution and load, and the importance of providing reactive power locally. The description of selected control features of shunt power systems such as SVC (Static Var Compensator)static compensators of reactive power, STATCOM-type systems (Static Compensator), static reactive power generators and systems that combine both these solutions, which are referred to as SVC based on STATCOM were not left out. It explains the need to improve the voltage stability of Power system, as well as the increasing requirements for energy quality and security. It also discusses the techniques that were adopted in controlling and monitoring of the rate of power flow in the entire power system topology. This investigates the system to an optimal level in order to reduce losses and ensures sufficiency of reactive power control during normal and emergency conditions and to prevent voltage collapse.
Effectiveness of core stability training and dynamic stretching in rehabilitation of chronic low back pain patients (2019)

To evaluate the effectiveness of core stability training and dynamic stretching on thoracolumbar range of motion (ROM), pain level and functional disability among chronic low back pain patients. Forty-three participants aged from 19-67 years old with the primary complaint of low back pain of more than 12 weeks’ duration were assigned to three groups: core stability (CS) (n=17), dynamic stretching (DS) (n=16) and control (n=12). All participants received regular thermotherapy and electrotherapy from the hospital rehabilitation unit. The CS group and DS groups were assigned with additional training, namely core stability training and dynamic stretching training programs for the respective groups. No additional training was given to the control group. The participants’ thoracolumbar range of motion (ROM), pain level and functional disability were tested over four different testing periods (pre, acute, ongoing, post). The current study shows both the CS group and DS group show significant improvement (p<0.05) in thoracolumbar ROM (CS group; η p 2 = 0.50, CS group; η p 2 = 0.66), pain level (CS group; η p 2 = 0.85, CS group; η p 2 = 0.81), and functional disability (CS group; η p 2 = 0.65, CS group; η p 2 = 0.82). In summary, both core stability exercise and dynamic stretching are effective in improving thoracolumbar ROM, pain-level, functional disability among chronic low back pain patients.
Biopolymer Electrospun Nanofiber Mats to Inactivate and Remove Bacteria (2021)

This dissertation investigates the cognitive mechanism underlying language users' ability to generalize probabilistic phonological patterns in their lexicon to novel words. Specifically, do speakers represent probabilistic patterns using abstract grammatical constraints? If so, this system of constraints would, like categorical phonological generalizations (a) be limited in the space of possible generalizations it can represent, and (b) apply to known and novel words alike without reference to specific known words. I examine these two predictions, comparing them to the predictions of alternative models. Analogical models are specifically considered. In chapter 3 I examine speakers' productions of novel words without near lexical neighbors. Speakers' productions of these novel words are compared to actual (relatively distant) words which could serve as an analogical base. Participants successfully extended a probabilistic trend in the lexicon to novel words, and did not use the analogical bases to do so: the contents of an analogical base for a given nonword did not predict participants' behavior on that nonword. In chapter 4 I discuss a case of mismatch with the lexicon - participants extend a near-categorical trend in the lexicon to novel words, but they undermatch the distribution found in the lexicon. This undermatching would not be predicted if learners could induce arbitrarily complex constraints. I argue instead that the trend is represented grammatically, and that the mismatch arises because of a bias for simpler constraints either in learning or in the structure of the grammar itself. If probabilistic phonological generalizations are represented abstractly, how do they interact with the lexicon of stored word forms? I address this issue in chapter 2 by looking at the perception of known and novel forms. ERP data demonstrates that a productive probabilistic trend influences the early stages of the lexical access process, specifically in known words. I consider two possible mechanisms for this: (1) that the lexical entries of known exceptional forms differ from known trend-observing forms, or (2) that the process of accessing an exceptional form involves a violation of expectations imposed by the grammar, and thus requires more processing power than the process of accessing a trend-observing form.
The Disqualification Dilemma: DR 5-105(D) of the Code of Professional Responsibility (1977)

A controversy is brewing between the American Bar Association Committee on Ethics and Professional Responsibility and the Legal Ethics Committee of the District of Columbia Bar Association over the proper interpretation to be given to the new version of DR 5-105(D) of the Code of Professional Responsibility. The broad language of the amendment has potential application to lawyers all over the country. This article provides a brief background on the disqualification issues involved in DR 5-105(D), examines the two different opinions, and then offers some comments on the debate over the proper interpretation of the new rule.
Hábitos de alimento de juveniles y adultos de Archosargus probatocephalus (Teleostei: Sparidae) en un estuario tropical de Veracruz (2007)

Para analizar los hábitos de alimento de juveniles y adultos de A. probatocephalus, durante un ciclo anual se realizaron ciclos bimestrales de 24 h, en dos tipos de hábitat (con y sin vegetación sumergida), en la laguna de Pueblo Viejo. La especie mostró una dieta global omnívora constituida por invertebrados (principalmente peracáridos) y plantas ( #8729;80%), siendo el detritus ( #8729;20%) una fuente secundaria. Los juveniles (individuos pequeños) tendieron a consumir más invertebrados pequeños (57%), mientras que los adultos (individuos grandes) consumieron más plantas (40%). Algunos de estos cambios dietéticos están asociados con un aumento de la longitud relativa del intestino a medida que los peces crecieron. En el hábitat con pastos y durante la época de secas predominaron los juveniles, quienes mostraron un mayor consumo de invertebrados como copépodos y peracáridos, mientras que en el hábitat sin vegetación y durante la época de lluvias predominaron los adultos, los cuales consumieron más plantas y detritus. Aunque la dieta fue muy similar entre el día y la noche, la intensidad de la alimentación fue mayor durante el día (P=0.041), lo que sugiere que la especie es un depredador diurno. La historia de vida de la especie en la laguna de Pueblo Viejo, muestra adaptaciones tendientes a maximizar el aprovechamiento de la disponibilidad temporal y espacial, de los recursos tróficos.
The Weird and Wonderful World of Bacterial Ribosome Regulation (2007)

In every organism, translation of the genetic information into functional proteins is performed on the ribosome. In Escherichia coli up to 40% of the cell's total energy turnover is channelled toward the ribosome and protein synthesis. Thus, elaborate networks of translation regulation pathways have evolved to modulate gene expression in response to growth rate and external factors, ranging from nutrient deprivation, to chemical (pH, ionic strength) and physical (temperature) fluctuations. Since the fundamental players involved in regulation of the different phases of translation have already been extensively reviewed elsewhere, this review focuses on lesser known and characterized factors that regulate the ribosome, ranging from processing, modification and assembly factors, unusual initiation and elongation factors, to a variety of stress response proteins.
Differentially slotted and differentially filled PIFAs (2003)

Based on a radiating and balanced mode decomposition it is shown that a planar inverted F antenna (PIFA) with a slot between the feed and shorting pins (differentially slotted PIFA) gives improved impedance control and a slightly wider bandwidth. The bandwidth can be further enhanced using a PIFA that is partially filled with conductor between the feed and shorting pins (differentially filled PIFA) and tuned with a capacitor.
Effects of Trifluralin and Organophosphorus Compounds on Cotton Seedlings (1971)

Soil applications of α,α,α,-trifluoro-2,6-dinitro- N,N -dipropyl- p -toluidine (trifluralin), O,O -diethyl S -((ethylthio)methyl)-phosphorodithioate (phorate) and their combinations did not affect cotton ( Gossypium hirsutum L.) germination. Plants grown on soil treated with trifluralin were shorter than plants on soil treated with phorate. High rates of phorate reduced shoot weights. Root weights of phorate-treated plants were higher than those of trifluralin-treated plants but lower than those of the controls. In culture solution and soil, trifluralin inhibited lateral roots of cotton. In the presence of phorate, trifluralin-treated plants produced more lateral roots than plants treated with trifluralin alone. Other organophosphorus compounds, when used in combination with trifluralin, did not increase the number of lateral roots.
The Stoic Model (1992)

Abstract This chapter pursues a more radical line of interpretation by developing some hypothetical theses concerning the Stoic analysis of the physical world. This approach explores some conceptual alternatives to the Aristotelian and quantum models of spatial magnitude, time, and motion. The first section explores the Stoic removal of limit entities from the physical world, which results in a sort of intuitive continuity of to holon, the entire physical cosmos. The second section considers the doctrine of locomotion athroōs.
A Scheme of Streaming Media Digital Rights Management in Cloud Conditions (2016)

It has been a widely concerned problem for the video producers and copyright business that how their digital content can be stored, retrieved and disseminated securely and effectively. Using the ability of cloud computing is an effective and convenient way to achieve processing a large number of video data. Aiming at how to protect the video content storage, distribution and using, meanwhile protecting the users' privacy, a DRM framework(VOD/LIVE) capable of supporting main streaming media service in cloud conditions has been proposed in this paper. The framework can provide rapid and variable granularity encryption module, real-time and efficient key distribution module and lightweight, transmission security authentication and authorization module three parts. The security, efficiency, scalability and access control granularity are compared in this paper with the traditional DRM system in the cloud-based streaming media service framework.
Synchronization Modulation Increases Transepithelial Potentials in MDCK Monolayers through Na/K Pumps (2013)

Transepithelial potential (TEP) is the voltage across a polarized epithelium. In epithelia that have active transport functions, the force for transmembrane flux of an ion is dictated by the electrochemical gradient in which TEP plays an essential role. In epithelial injury, disruption of the epithelial barrier collapses the TEP at the wound edge, resulting in the establishment of an endogenous wound electric field (∼100 mV/mm) that is directed towards the center of the wound. This endogenous electric field is implicated to enhance wound healing by guiding cell migration. We thus seek techniques to enhance the TEP, which may increase the wound electric fields and enhance wound healing. We report a novel technique, termed synchronization modulation (SM) using a train of electric pulses to synchronize the Na/K pump activity, and then modulating the pumping cycles to increase the efficiency of the Na/K pumps. Kidney epithelial monolayers (MDCK cells) maintain a stable TEP and transepithelial resistance (TER). SM significantly increased TEP over four fold. Either ouabain or digoxin, which block Na/K pump, abolished SM-induced TEP increases. In addition to the pump activity, basolateral distribution of Na/K pumps is essential for an increase in TEP. Our study for the first time developed an electrical approach to significantly increase the TEP. This technique targeting the Na/K pump may be used to modulate TEP, and may have implication in wound healing and in diseases where TEP needs to be modulated.
