Absence of Their HLA Ligands Associated with Inhibitory KIR in the among African Female Sex Workers Is Cutting Edge: Resistance to HIV-1 Infection

NK cells are regulated in part by killer Ig-like receptors (KIR) that interact with HLA molecules on potential target cells. KIR and HLA loci are highly polymorphic and certain KIR/HLA combinations were found to protect against HIV disease progression. We show in this study that KIR/HLA interactions also influence resistance to HIV transmission. HIV-exposed but seronegative female sex workers in Abidjan, Coˆte d’Ivoire, frequently possessed inhibitory KIR genes in the absence of their cognate HLA genes: KIR2DL2/KIR2DL3 heterozygosity in the absence of HLA-C1 and KIR3DL1 homozygosity in the absence of HLA-Bw4 . HIV-seropositive female sex workers were characterized by corresponding inhibitory KIR/HLA pairings: KIR2DL3 homozygosity together with HLA-C1 and a trend toward KIR3DL1 / HLA-Bw4 homozygosity. Absence of ligands for inhibitory KIR could lower the threshold for NK cell activation. In addition, exposed se-ronegatives more frequently possessed AB KIR genotypes, which contain more activating KIR . The data support an important role for NK cells and KIR/HLA interactions in antiviral immunity. The Journal of Immunology, 2006, 177: 6588–6592.
ANALYTICAL SOLUTIONS TO EDDY--CURRENT PROBE COIL PROBLEMS.

Solutions have been obtained for axially symmetric eddy‐current problems in two configurations of wide applicability. In both cases, the eddy currents are assumed to be produced by a circular coil of rectangular cross section, driven by a constant amplitude alternating current. One solution is for a coil above a semi‐infinite conducting slab with a plane surface, covered with a uniform layer of another conductor. This solution includes the special cases of a coil above a single infinite plane conductor or above a sheet of finite thickness, as well as the case of one metal clad on another. The other solution is for a coil surrounding an infinitely long circular conducting rod with a uniformly thick coating of another conductor. This includes the special cases of a coil around a conducting tube or rod, as well as one metal clad on a rod of another metal. The solutions are in the form of integrals of first‐order Bessel functions giving the vector potential, from which the other electromagnetic quantities of .
Coherence of The Knowledge Base and Firm Innovative Performance: Evidence from the Us Pharmaceutical Industry

We examine the relationship between the coherence of the knowledge base and the innovative performance of US pharmaceutical firms during the nineties. We develop measures of the coherence and scope of firms’ knowledge base. Count data regression models show a strong link between these two properties and firms’ innovative performance. Firms experience decreasing returns to scale in research but larger firms enjoy a significant size advantage in innovation. Knowledge flows are necessary in knowledge production but not sufficient to secure its quality. Over time, the contribution of the scope and coherence of the knowledge base is increasing.
Patent Threat Analysis Search Engine

-This paper proposes a framework for a patent threat analysis search engine. The framework employs text mining based on the patent map approach to identify which particular patent is similar to the one in dispute. The patent map is a visual representation that uses technological proximities among patents. The patent threat analysis method will analyze patent infringement issues from judgements in the USA and Europe. Having examined and compared the patent map and patent infringement analysis, we can identify what kind of product and technology are subject to the threat of patent infringement with the help of solution integration and analysis of the two different databases.
Unsupervised Information-Based Feature Selection for Speech Therapy Optimization by Data Mining Techniques

— Data mining was proven to be an efficient way to find new and useful knowledge in data. Since data dimensionality has major implications on the performance of the algorithms used, one of the data pre-processing operations refers to reducing the number of features. One way to do that is feature selection based on their relevance and redundancy analysis. This paper presents a feature selection method which is applied on data provided by TERAPERS – a computer-based speech therapy system for Romanian children suffering of dyslalia.

Sequence Analysis and Comparison of int and xis Genes from Staphylococcal Bacteriophages L54a and +11

The DNA fragment encoding the integrase and excisionase genes involved in site-specffic recombination of staphylococcal bacteriophage +11 was cloned and sequenced. The int and xis genes and the recombination site, attP, were highly clustered in a 1.7-kilobase DNA fragment with the gene order attP-int-xis. The int and xis genes were transcribed divergently, with the int gene transcribed toward the attp site and the xis gene transcribed away from the attP site. The deduced Int is a basic protein of 348 residues with an estimated molecular weight of 41,357. In contrast, the deduced Xis is an acidic protein containing 66 amino acids with an estimated molecular weight of 7,621. The site-specific recombination system of +11 was compared with that of a closely related bacteriophage, L54a.
The effectiveness of transformational leadership: a qualitative-based study on millennial perceptions in South Africa.

The purpose of this article/study is to examine whether the individualistic nature of millennials undermines the efforts of transformational leadership in achieving organizational objectives. Design/methodology/approach – The study adopted a qualitative research method with a semi-structured interview approach, using 10 millennial professionals in South Africa. The participants had attained at least two years of work experience across different industries with diverse specialisms. The Interviews were transcribed and a thematic analysis was adopted to analyze the data. Findings - The findings revealed that where organizational objectives and millen nials aspirations conflict, a leader’s ability to creatively manage and motivate millennials to prioritize the organization’s goals over their ambitions, will result in a productive outcome for both. Thus, the argument that leaders who show caring dispositions, provide frequent feedback as well as recognize the contribution of millennials; are strategically placed, to lead them in re-orienting their aspirations towards the realization of organizational goals. Originality/Value - Although some studies have proposed that follower characteristics may moderate the effectiveness of transformational leadership, there is little/no empirical research to confirm this proposition. However, this study/article contributes to the transformational leadership debate, contending that millennials are organizational asset possessing creative, novel and proactive energy, which should be managed in the broader context of organizational objectives to enhance their welfare and that of the organization respectively. motivation, individualistic nature and 21st century workplace
Performance Analysis of Various Modulation Techniques for different Channel Models for IEEE 802.16 standard.

-Broadband wireless is about bringing the broadband experience to a wireless context, which offers users certain unique benefits and convenience. Because of its wireless nature, it can be faster to deploy, easier to scale and more flexible, thereby giving it the potential to serve customers not served or not satisfied by their wired broadband alternatives. The broadband wireless access has become the best way to meet escalating business demand for rapid internet connection and integrated "triple play" services. There are two fundamentally different types of broadband wireless services. The first type attempts to provide a set of services similar to that of the traditional fixed-line broadband but using wireless as the medium of transmission. This type, called fixed wireless broadband , can be thought of as a competitive alternative to DSL or cable modem. The second type of broadband wireless, called mobile broadband, offers the additional functionality of portability and mobility.

REVO: A flexible, volumetric approach to mesh construction

Meshes are used in a variety of applications to specify the three dimensional (3D) shapes of objects in simulated scenes. For example, a mesh can be used as an animal in an animation movie, a soldier in a video game, or a bulldozer in a simulation application. A straightforward way of creating a mesh is to modify an existing mesh. Although several mesh modification algorithms exist, there is a need for an algorithm that constructs a mesh from any combination of existing meshes and simple geometric shapes (called primitives) according to a list of user commands. When visualized, the resulting mesh should have a smooth (i.e. not blocky) surface. We propose the Revo method for constructing meshes from any combination of existing meshes or primitives according to user commands. The commands required to construct a specific 3D mesh should be determined by an artist. First, the Revo method generates a volumetric representation of each input mesh or primitive. To do so, for each input mesh, it imposes a 3D grid called a volumetric grid on the portion of the 3D world that contains the mesh. Revo may apply some transformations to an input mesh to ensure that it is completely enclosed by the volumetric grid. A distance field is used to approximate the input mesh in the volumetric grid. Similarly, each required primitive is constructed in a volumetric grid to yield a distance field. A series of distance-based operations, such as union, intersection, and subtraction, are used to combine the distance fields according to the user commands. Finally, Revo extracts the implicit surface from the resulting distance field and constructs a mesh. We analyzed the Revo method theoretically and empirically. Our analysis shows
Non-orthogonal Multiple Access in Large-Scale Hybrid Heterogeneous Networks

—The potential beneﬁts of applying non-orthogonal multiple access (NOMA) technique into K -tier hybrid heterogeneous networks (HetNets) is exploited. A new promising transmission framework is proposed, in which NOMA technique is adopted in small cells and massive multiple-input multiple-output (MIMO) is employed in macro cells. For maximizing the biased average received power at mobile users, a NOMA and massive MIMO based user association scheme is developed. In an effort to evaluate the performance of the proposed framework, we ﬁrst derive the analytical expressions for the coverage probability of NOMA enhanced small cells. We then examine the spectrum efﬁciency of the whole proposed networks, with deriving exact analytical expressions for NOMA enhanced small cells and a tractable lower bound for massive MIMO enabled macro cells. Lastly, we investigate the energy efﬁciency of the hybrid HetNets with the aid of a poplar energy consumption model. Our results conﬁrm that: 1) The coverage probability of NOMA enhanced small cells is affected to a large extent by the targeted transmit rates and power sharing coefﬁcients of two NOMA users; 2) Massive MIMO enabled macro cells are capable of signiﬁcantly enhancing the spectrum efﬁciency by increasing the number of antennas; 3) The energy efﬁciency of the whole networks can be greatly improved by densely deploying NOMA enhanced small cell base stations (BSs); and 4) The proposed NOMA enhanced HetNets transmission scheme has superior performance compared to the orthogonal multiple access (OMA) based HetNets.
Hospital Waste and Cleaning Workers in Baquba Teaching Hospital

Background: Medical waste is potentially hazardous, infectious, and toxic materials. It therefore requires special handling and disposal practices. Aims: To determine: 1. Baquba hospital Subjects and Methods: A cross-sectional study was conducted among a random sample of (80) employees in Baquba teaching hospital in May 2011. Self-administered questionnaire which included occupational, organisational factors and sociodemographic variables was used. In addition, researcher observed collection, segregation, transportation, and disposal of medical waste at the hospital. Result: Most of the cleaning workers are younger age (35 year ), male 85%, the rate of illiteracy among cleaners in the hospitals was high 47.5%, the highest level of knowledge about hazard categories of medical waste had worked for (2–5 years), the cleaners are focused mainly on the sharps particles first degree, percentage who reported sharps as medical waste about 98%. Conclusion: Most cleaning workers lacked sufficient awareness of impacts of poor clinical waste disposal and had never heard of any policy national or international on safe clinical waste management. Methods of collecting, segregating, transporting and disposing clinical waste at the hospital was poor.
DISTINCT NEUTROPHIL RESPONSES TO ORAL COMMENSAL AND PATHOGENIC BIOFILMS

Periodontal disease, one of the most prevalent inflammatory conditions affecting millions of people each year, is initiated by microbial dysbiosis. The accumulation of bacteria in the gingival sulcus results in the recruitment of host immune cells, mostly neutrophils and, when excessive, can trigger a chronic inflammatory response leading to periodontitis. Neutrophils make up 50-70% of the white blood cells and are the first line of defense against bacterial biofilm forming around the teeth. Using flow cytometry, we have characterized neutrophil responses to several significant oral commensal and pathogenic bacteria by assaying the changes in neutrophil surface expressions of specific clusters of differentiation (CD) markers, induction of ROS production and NETosis. In this study, we are able to show that certain commensal bacteria activate neutrophils more than pathogenic bacteria thus providing better insight into the etiology of periodontal disease.
The Influence of Phenotyping Method on Structural Neuroimaging Associations with Depression in UK Biobank

Background: Depression is assessed in many different ways, with large population studies often relying on minimal phenotyping approaches. Genetic results suggest that more formal clinical diagnoses and simpler self-report measures of depression show some core similarities, but also important differences. It is not yet clear whether this is also the case for neuroimaging measures. Methods: We studied 39,300 UK Biobank imaging participants (20,701 female; aged 44.6 to 82.3 years, M = 64.1, SD = 7.5) with structural neuroimaging (T1 and DTI) and depression data. Depression phenotypes included a minmal single-item self-report measure, an intermediate symptom-based measure of ‘probable’ depression, and a more clinically robust measure based on DSM-IV criteria. We tested i) associations between brain structural measures and each depression phenotype, and ii) the effects of depression phenotype on these associations. Results: Small depression-brain structure associations (β < 0.1) were significant after FDR correction for many global and regional metrics for all three phenotypes. The most consistent imaging associations across depression phenotypes were for measures of white matter integrity. There were small but significant effects of phenotype definition primarily for cortical thickness, which showed stronger negative associations with Self-reported Depression than the symptom-based measures. Conclusion: Similar to previous genetic studies, we found some consistent associations indicating a core component of depression across phenotypes, and some additional associations that were phenotype-specific. Although these specific results did not relate to depth of phenotyping as expected, effects of phenotype definition are still an important consideration for future depression research. interpreting research on the disorder. Despite differences between depression phenotypes, our results also provide evidence for core neuroimaging features of depression in terms of decreased integrity of thalamic radiations and association fibres across different ways of defining the disorder.

(cid:97) 1 -Adrenergic Stimulation of Sarcolemmal Na (cid:49) -H (cid:49) Exchanger Activity in Rat Ventricular Myocytes Evidence for Selective Mediation by the (cid:97) 1A -Adrenoceptor Subtype

— (cid:97) 1 -Adrenoceptor ( (cid:97) 1 -AR) stimulation increases sarcolemmal Na (cid:49) -H (cid:49) exchanger (NHE) activity. The present study was designed to determine the role(s) of (cid:97) 1 -AR subtype(s) in mediating this response. As an index of NHE activity, acid efflux rates ( J H s) were determined in single rat ventricular myocytes loaded with the pH-sensitive fluoroprobe carboxy-seminaphthorhodafluor-1 after 2 consecutive intracellular acid pulses in bicarbonate-free medium. J H at pH i 6.90 did not change significantly during the second pulse relative to the first in control cells but increased in a dose-dependent manner when the second pulse occurred in the presence of phenylephrine (nonselective (cid:97) 1 -AR agonist) or A61603 ( (cid:97) 1A -AR–selective agonist), with EC 50 values of 1.24 (cid:109) mol/L and 3.6 nmol/L, respectively (both agonists given together with 1 (cid:109) mol/L atenolol). Stimulation of NHE activity by 10 (cid:109) mol/L phenylephrine was inhibited in a dose-dependent manner by the competitive antagonists prazosin, WB4101, and 5-methylurapidil, with IC 50 values of 12, 32, and 149 nmol/L, respectively. Analyses of the relative EC 50 and IC 50 values obtained (and K i values estimated from the antagonist IC 50 s) in relation to the relative potencies of these agents at native rat (cid:97) 1 -AR subtypes and their relative affinities for recombinant rat (cid:97) 1 -ARs suggest that (cid:97) 1 -adrenergic stimulation of sarcolemmal NHE activity is likely to be mediated selectively by the (cid:97) 1A -AR.
