Neuropsychological functioning in cortical-basal ganglionic degeneration

Patients with cortical-basal ganglionic degeneration (CBGD) display prominent rigidity and apraxia, exhibit an asymmetric onset of symptoms, and may show other symptoms including abnormal saccadic eye movements, the "alien limb" sign, limb dystonia, and myoclonus. We compared the neuropsychological test performances of 21 CBGD patients with 21 Alzheimer's disease (AD) patients displaying no extrapyramidal symptoms and with 12 ADA patients who did show such symptoms. Groups were matched for age, educational level, and overall severity of dementia. Since the cognitive deficit was mild in most CBGD patients, most AD patients included in this study were also only mildly demented. The CBGD patients performed significantly better than the AD patients on test of immediate and delayed recall of verbal material; whereas the AD patients (with or without extrapyramidal symptoms) performed better on tests of praxis, finger tapping speed, and motor programming. The CBGD and AD groups all displayed prominent deficits on tests of sustained attention/mental control and verbal fluency, and exhibited mild deficits on confrontation naming. The CBGD patients endorsed significantly more depressive symptoms on the Geriatric Depression Scale.
Discriminative k-means clustering

The k-means algorithm is a partitional clustering method. Over 60 years old, it has been successfully used for a variety of problems. The popularity of k-means is in large part a consequence of its simplicity and efficiency. In this paper we are inspired by these appealing properties of k-means in the development of a clustering algorithm which accepts the notion of “positively” and “negatively” labelled data. The goal is to discover the cluster structure of both positive and negative data in a manner which allows for the discrimination between the two sets. The usefulness of this idea is demonstrated practically on the problem of face recognition, where the task of learning the scope of a person's appearance should be done in a manner which allows this face to be differentiated from others.
N-acetylcysteine for radiocontrast-induced nephropathy: potential role in the emergency department?

OBJECTIVE To systematically review the efficacy and safety of N-acetylcysteine (NAC) for the prevention of radiocontrast-induced nephropathy (RIN), and to discuss its potential role in the emergency department. METHODOLOGY We conducted a search of MEDLINE (from 1966 to December 2003), PubMed (1966 to December 2003) and EMBASE (1988 to December 2003) for English-language, prospective, randomized, controlled trials in humans using the search terms N-acetylcysteine, acetylcysteine, radiopharmaceuticals, contrast media, and kidney failure (acute). RESULTS Five trials support and 4 trials refute the hypothesis that NAC helps prevent RIN. In 7 of 9 trials, oral NAC was administered twice daily for 2 days, on the day before and on the day of the radiocontrast study--a regime not feasible for emergent situations. More recent trials suggest that adequate hydration and lower volumes of radiocontrast, rather than NAC, are more effective ways to prevent RIN. CONCLUSION Although further study may be indicated, current evidence does not suggest that NAC has a role in the emergency prevention of RIN.
Acoustic satellite behaviour in the Australian bushcricket Elephantodeta nobilis (Phaneropterinae, Tettigoniidae, Orthoptera)

Male and female Elephantodeta nobilis duet with the female responding to the male's long and complex call. The duetting male's call consisted of four parts, described here as parts A, B, C and D. We found that the female replied 570 ms after the male's D pulse, which followed the extended part B and short click of part C. Noncalling males were attracted to the duet and often used satellite tactics by inserting a volley of clicks 200 ms before the alpha male's D pulse. Satellite males used part C of the alpha male song to cue their own call and this inserted call induced females to reply earlier compared with the alpha male call alone. Alpha males often extended their calls with additional D-type calls and so we examined the effectiveness of these calls as countermeasures to satellite calling. There was no influence of this alpha strategy on the satellite's propensity to call although more calls from the alpha male did cause the female to reply more frequently. We also examined the effect of relative intensity of alpha and satellite calls on the female's reply. Reduced satellite intensity increased the variance in the timing of the female response. Finally, we tested the effectiveness of the satellite's call on female phonotaxis within a two-speaker arena. Although females preferred the alpha male they were nevertheless attracted to the satellite calls regardless of the latter's relative intensity. We discuss the possible role of satellite calling as a novel conditional strategy. Copyright 2000 The Association for the Study of Animal Behaviour.
A literature review of the association between wear rate and osteolysis in total hip arthroplasty.

The establishment of a polyethylene wear rate threshold for the development of osteolysis at the hip would allow surgeons to identify patients at risk for osteolysis and to implement selective, more frequent follow-up. We reviewed publications that met certain criteria for wear and osteolysis measurement. Based on this review, the incidence of osteolysis increases as the rate of wear increases. The literature indicates that osteolysis rarely is observed at a wear rate of <0.1 mm/y. We suggest that a practical wear rate threshold of 0.05 mm/y would eliminate osteolysis. This wear threshold suggests that the new cross-linked polyethylenes would reduce osteolysis, provided that in vivo wear rates mirror those observed in vitro. To facilitate future comparison of published data, we suggest that longitudinal wear studies adopt consistent edge detection-based wear measurement techniques and uniform osteolytic lesion classification and measurement schema.
Linearized Bregman iterations for compressed sensing

Finding a solution of a linear equation Au = f with various minimization properties arises from many applications. One such application is compressed sensing, where an efficient and robust-to-noise algorithm to find a minimal l 1 norm solution is needed. This means that the algorithm should be tailored for large scale and completely dense matrices A, while Au and A T u can be computed by fast transforms and the solution we seek is sparse. Recently, a simple and fast algorithm based on linearized Bregman iteration was proposed in [28, 32] for this purpose. This paper is to analyze the convergence of linearized Bregman iterations and the minimization properties of their limit. Based on our analysis here, we derive also a new algorithm that is proven to be convergent with a rate. Furthermore, the new algorithm is simple and fast in approximating a minimal l 1 norm solution of Au = f as shown by numerical simulations. Hence, it can be used as another choice of an efficient tool in compressed sensing.
Baltic Journal of Health and Physical Activity Positive Personality Traits As an Element of Creating the Image of Positive Personality Traits As an Element of Creating the Image of a Physical Education Teacher a Physical Education Teacher

Background: To create a positive image among students, a Physical Education teacher should get to know their expectations and visions. The aim of the work was to identify the most significant positive traits which a Physical Education teacher should possess and to identify relations between variables determining students’ choices. Material/Methods: The results obtained from 744 students (471 females and 273 males) from two upper-secondary schools (1 st school n=393; 2 nd school n=351) were analysed. The research used a diagnostic poll method – questionnaires. Respondents were asked a half-open question and were supposed to indicate three most significant positive features which should characterise a Physical Education teacher. The analysis was made with the use of the log-linear modelling method. Results: The research indicated the most desired features which should characterise a Physical Education teacher. The analysis of relations (p<0.05) between independent variables (school x gender x year) and a dependent variable (selection of a particular characteristic) allowed revealing a second-order interaction for five traits (calm, caring, understanding, trustworthy, having a sense of humour) and a third-order interaction for three personality traits (fair, benevolent and consistent). There did not appear any relations between independent variables and the selection of such personality traits as self-possessed, friendly and being a partner. Conclusions: Features which, according to students, should characterise a Physical Education teacher should serve as foundations for building a positive image or as the basis for modifying the existing one. Moreover, such knowledge of factors influencing the differentiation of the
Urban agriculture and sustainable livelihoods

Since colonial times, Kenyan women have developed mechanisms to cope with their changing social and economic circumstances. Structural Adjustment Policies (SAPs), instituted by the International Monetary Fund (IMF) and World Bank as a solution to the debt crisis in developing countries, prompted many women to move from their previous activities in subsistence farming to engage more in income-generating activities such as beer brewing, marketing food products, trading other commodities, and prostitution. The strategies used by women during the period between Kenya’s independence from colonial rule and the introduction of SAPs in the early 1980s are familiar in literature on Kenyan women. Additional mechanisms used by women to maintain their families over the last decade have also been poorly explored but they’re important to the contemporary context of Kenyan development. While maintaining established coping strategies, Kenyan women have also been innovative in their approaches to dealing with worsening economic conditions throughout the country. When one examines contemporary activities of Kenyan women, one particular strategy stands out but has not been examined in the literature. This coping mechanism, the proliferation of urban agricultural activities, will be examined in the context of Kenya’s current political economy.
Towards automated protocol reverse engineering using semantic information

Network security products, such as NIDS or application firewalls, tend to focus on application level communication flows. However, adding support for new proprietary and often undocumented protocols, implies the reverse engineering of these protocols. Currently, this task is performed manually. Considering the difficulty and time needed for manual reverse engineering of protocols, one can easily understand the importance of automating this task. This is even given more significance in today's cybersecurity context where reaction time and automated adaptation become a priority. Several studies were carried out to infer protocol's specifications from traces. As shown in this article, they do not provide accurate results on complex protocols and are often not applicable in an operational context to provide parsers or traffic generators, some key indicators of the quality of obtained specifications. In addition, too few previous works have resulted in the publication of tools that would allow the scientific community to experimentally validate and compare the different approaches. In this paper, we infer the specifications out of complex protocols by means of an automated approach and novel techniques. Based on communication traces, we reverse the vocabulary of a protocol by considering embedded contextual information. We also use this information to improve message clustering and to enhance the identification of fields boundaries. We then show the viability of our approach through a comparative study including our reimplementation of three other state-of-the-art approaches (ASAP, Discoverer and ScriptGen).
Generation of Functional Neuromuscular Junctions from Human Pluripotent Stem Cell Lines

Several neuromuscular diseases involve dysfunction of neuromuscular junctions (NMJs), yet there are no patient-specific human models for electrophysiological characterization of NMJ. We seeded cells of neurally-induced embryoid body-like spheres derived from induced pluripotent stem cell (iPSC) or embryonic stem cell (ESC) lines as monolayers without basic fibroblast factor (bFGF) and observed differentiation of neuronal as well as spontaneously contracting, multinucleated skeletal myotubes. The myotubes showed striation, immunoreactivity for myosin heavy chain, actin bundles typical for myo-oriented cells, and generated spontaneous and evoked action potentials (APs). The myogenic differentiation was associated with expression of MyoD1, myogenin and type I ryanodine receptor. Neurons formed end plate like structures with strong binding of α-bungarotoxin, a marker of nicotinic acetylcholine receptors highly expressed in the postsynaptic membrane of NMJs, and expressed SMI-32, a motoneuron marker, as well as SV2, a marker for synapses. Pharmacological stimulation of cholinergic receptors resulted in strong depolarization of myotube membrane and raised Ca2+ concentration in sarcoplasm, while electrical stimulation evoked Ca2+ transients in myotubes. Stimulation of motoneurons with N-Methyl-D-aspartate resulted in reproducible APs in myotubes and end plates displayed typical mEPPs and tonic activity depolarizing myotubes of about 10 mV. We conclude that simultaneous differentiation of neurons and myotubes from patient-specific iPSCs or ESCs results also in the development of functional NMJs. Our human model of NMJ may serve as an important tool to investigate normal development, mechanisms of diseases and novel drug targets involving NMJ dysfunction and degeneration.
Supporting Self-Regulated Learning for College Students with Asperger Syndrome: Exploring the “Strategies for College Learning” Model

In this study, I piloted the feasibility, effects, and perceived acceptability of a peer mentoring intervention targeting academic achievement and self-regulated learning (SRL) for three college students with Asperger syndrome. The approach, dubbed Strategies for College Learning (SCL), features individualized assessment of academic performance in target courses and direct instruction of learning and self-regulation strategies under the provision of a peer mentor. The pilot study resulted in successful implementation of SCL and the acquisition of numerous learning strategies among participants. Qualitative data indicated participants felt SCL was both useful and acceptable. As the incidence of autism spectrum disorders increases, so has the need to accommodate students with highly individualized learning needs. The pilot is among the first to explore peer mentoring as an approach at bolstering SRL and academic achievement for college students with Asperger syndrome. The limitations of the study are discussed as well as implications for future research and practice.
Scalable Collaborative Filtering Recommendation Algorithm with MapReduce

Collaborative Filtering (CF) algorithm is the common solution to Recommender System (RS). With the development of network and storage technology, the amount of users and items in RS system is exclusively growing. How to increase the scalability and recommendation accuracy of CF are the main concerns in the related research. In this paper, an efficient implementation for user-based CF algorithm on MapReduce is presented. We exploit Bag of Word (BoW) method and design a hierarchical inverted index to further increase the scalability of our method. Meanwhile, a soft-assignment mechanism for the hierarchical inverted index is proposed to make up the recommendation accuracy decrease caused by the index. The Mapreduce implementations of our methods are detailed discussed and analyzed on both simulated data and real data, demonstrating that our implementation has the ability to scale to huge numbers of users and items, eanwhile ensures recommendation accuracy.
Exploring physical activity monitoring devices for diabetic and obese patients

The World Health Organization highly recommends physical activities to control diabetes and obesity. Research on pervasive fitness devices is on the rise, but little attention has been given to how diabetic and obese patients use them to change their lifestyle. This paper reports the results of a one-month in-situ study with obese and diabetic patients. We interviewed 18 subjects using a set of carefully designed qualitative questions and let them use a fitness sensor called Fitbit for one month. Before the study, participants found it challenging to motivate themselves for physical exercise. One month later, they became aware of their sedentary lifestyles and started to perform more activities at a steady pace. Subsequently, patients reported rethinking of fitness and visible behavior changes.
Effect of tobacco smoking and smoking cessation on plasma lipoproteins and associated major cardiovascular risk factors: a narrative review

Abstract Cigarette smoking, active or passive, kills about 6 million people each year worldwide. Cardiovascular disease (CVD) is responsible for 40% of all smoking-related deaths, lung cancer accounts for 20% of all smoking-related deaths, and chronic obstructive pulmonary disease is related to another 20% of deaths. In this narrative review we consider the relationship between cigarette smoking and CVD. We discuss disease states and/or CVD risk factors related to smoking, such as dyslipidaemia, vascular inflammation, endothelial dysfunction, arterial stiffness, insulin resistance, type 2 diabetes mellitus (T2DM), chronic kidney disease (CKD), and non-alcoholic fatty liver disease (NAFLD) as well as their complex interrelations. Smoking cessation can correct abnormalities related to smoking; however, success rates are relatively low. In cases of inability to quit, measures to minimize the adverse effects of smoking specifically related to CVD should be taken. Smokers should receive best practice treatment, according to guidelines, as for non-smokers.
Comparison of Composition and Anticaries Effect of Galla Chinensis Extracts with Different Isolation Methods

Objectives: Galla chinensis water extract (GCE) has been demonstrated to inhibit dental caries by favorably shifting the demineralization/remineralization balance of enamel and inhibiting the biomass and acid formation of dental biofilm. The present study focused on the comparison of composition and anticaries effect of Galla chinensis extracts with different isolation methods, aiming to improve the efficacy of caries prevention. Methods: The composition of water extract (GCE), ethanol extract (eGCE) and commercial tannic acid was compared. High performance liquid chromatography coupled to electrospray ionization-time of flight-mass spectrometry (HPLC-ESI-TOF-MS) analysis was used to analyze the main ingredients. In vitro pH-cycling regime and polymicrobial biofilms model were used to assess the ability of different Galla chinensis extracts to inhibit enamel demineralization, acid formation and biofilm formation. Results: All the GCE, eGCE and tannic acid contained a high level of total phenolics. HPLC-ESI-TOF-MS analysis showed that the main ingredients of GCE were gallic acid (GA), while eGCE mainly contained 4-7 galloylglucopyranoses (GGs) and tannic acid mainly contained 5-10 GGs. Furthermore, eGCE and tannic acid showed a better effect on inhibiting enamel demineralization, acid formation and biofilm formation compared to GCE. Conclusions: Galla chinensis extracts with higher tannin content were suggested to have higher potential to prevent dental caries.
he apparently very variable potency of the anti-depressant uoxetine

The anti-depressant fluoxetine is widely present in the aquatic environment. Typical river concentrations are in the low ng/L range. Many ecotoxicity studies have assessed the effects of this pharmaceutical on a range of aquatic species. Some studies report that ng, or even pg, per litre concentrations cause effects, whereas other studies report that effects only occur when the water concentration is in the g/L range. vailable online 14 December 2013
Processing Speed and Longitudinal Trajectories of Change for Cognitive Abilities: The Swedish Adoption/Twin Study of Aging

In this manuscript, The Swedish Adoption/Twin Study of Aging (SATSA) is described. Although the study is a multidisciplinary program in gerontological genetics, the summary of findings focuses on the cognitive measures. In the second part of the manuscript, we investigate the role played by measures of processing speed in explaining the longitudinal trajectories of change for cognitive abilities and the genetic and environmental influences on those trajectories. When processing speed was regressed out of cognitive measures representing three cognitive domains (crystallized, fluid, and memory) and a general cognitive factor, the trajectory of decline was less severe. Quantitative genetic analyses indicated that environmental variance increases in late adulthood. A substantial portion of the genetic variance for these cognitive abilities was accounted for by genetic variance for speed. With increasing age, genetic variance associated with processing speed becomes a more prominent component of genetic variance for fluid abilities and for the general cognitive factor.
