A Dissociation Between Attention and Selection

It is widely assumed that the allocation of spatial attention results in the “selection” of attended objects or regions of space. That is, once a stimulus is attended, all its feature dimensions are processed irrespective of their relevance to behavioral goals. This assumption is based in part on experiments showing significant interference for attended stimuli when the response to an irrelevant dimension conflicts with the response to the relevant dimension (e.g., the Stroop effect). Here we show that such interference is not due to attending per se. In two spatial cuing experiments, we found that it was possible to restrict processing of attended stimuli to task-relevant dimensions. This new evidence supports two novel conclusions: (a) Selection involves more than the focusing of attention per se; and (b) task expectations play a key role in determining the depth of processing of the elementary feature dimensions of attended stimuli.
Multiple Sclerosis: A Literature Review

&NA; The pathology of multiple sclerosis (MS) was first described over 150 years ago. An estimated 250,000 to 350,000 people are affected with MS in this country. Young adults between the ages of 20 and 50 years are most commonly affected, with the majority of patients experiencing a relapsing course and progressive functional disability. To date, researchers have been unable to discover a precipitating cause. However, many now believe MS develops due to exposure to some unknown virus in a genetically predisposed individual. The incidence of disease is limited in temperate climates and higher in northern latitudes. Neuroscience nurses frequently care for individuals with MS and must, therefore, maintain a familiarity with the current literature and research.

The Rough Endoplasmic Reticulum-resident FK506-binding Protein FKBP65 Is a Molecular Chaperone That Interacts with Collagens*

The rough endoplasmic reticulum-resident FK-506-binding protein FKBP65 can be isolated from chick embryos on a gelatin-Sepharose column, indicating some involvement in the biosynthesis of procollagens. The peptidylprolyl cis-trans-isomerase activity of FKBP65 was previously shown to have only marginal effects on the rate of triple helix formation (Zeng, B., MacDonald, J. R., Bann, J. G., Beck, K., Gambee, J. E., Boswell, B. A., and Bächinger, H. P. (1998) Biochem. J. 330, 109–114). Here we show that FKBP65 is a monomer in solution and acts as a chaperone molecule when tested with two classic chaperone assays: FKBP65 inhibits the thermal aggregation of citrate synthase and is active in the denatured rhodanese refolding and aggregation assay. The chaperone activity is comparable to that of protein-disulfide isomerase, a well characterized chaperone. FKBP65 delays the in vitro fibril formation of type I collagen, indicating that FKBP65 is also able to interact with triple helical collagen, and acts as a collagen chaperone.
Retrieval of Leaf Area Index by Coupling Radiative Transfer Model and a Dynamic Model

A new algorithm is developed to estimate LAI from time-series MODIS reflectance data (MOD09A1) based on coupled radiative transfer model and process model. The radiative transfer model is coupled with an empirical LAI dynamic model to simulate the time series reflectances. An optimization method is used to adjust the values of the parameters of the coupled model to seek a model trajectory that best fits a set of observations in a given time window. The preliminary analysis using MODIS surface reflectance data at some fluxnet sites was performed to validate this method. The results show that the algorithm is able to produce spatially and temporally continuous LAI product efficiently, and the accuracy of the retrieved LAI has been significantly improved over the MODIS LAI product compared to the field measured LAI data.
Adding Chiropractic Manipulative Therapy to Standard Medical Care for Patients With Acute Low Back Pain: Results of a Pragmatic Randomized Comparative Effectiveness Study

Study Design. Randomized controlled trial. Objective. To assess changes in pain levels and physical functioning in response to standard medical care (SMC) versus SMC plus chiropractic manipulative therapy (CMT) for the treatment of low back pain (LBP) among 18 to 35-year-old active-duty military personnel. Summary of Background Data. LBP is common, costly, and a significant cause of long-term sick leave and work loss. Many different interventions are available, but there exists no consensus on the best approach. One intervention often used is manipulative therapy. Current evidence from randomized controlled trials demonstrates that manipulative therapy may be as effective as other conservative treatments of LBP, but its appropriate role in the healthcare delivery system has not been established. Methods. Prospective, 2-arm randomized controlled trial pilot study comparing SMC plus CMT with only SMC. The primary outcome measures were changes in back-related pain on the numerical rating scale and physical functioning at 4 weeks on the Roland-Morris Disability Questionnaire and back pain functional scale (BPFS). Results. Mean Roland-Morris Disability Questionnaire scores decreased in both groups during the course of the study, but adjusted mean scores were significantly better in the SMC plus CMT group than in the SMC group at both week 2 (P < 0.001) and week 4 (P = 0.004). Mean numerical rating scale pain scores were also significantly better in the group that received CMT. Adjusted mean back pain functional scale scores were significantly higher (improved) in the SMC plus CMT group than in the SMC group at both week 2 (P < 0.001) and week 4 (P = 0.004). Conclusion. The results of this trial suggest that CMT in conjunction with SMC offers a significant advantage for decreasing pain and improving physical functioning when compared with only standard care, for men and women between 18 and 35 years of age with acute LBP.
Urban residence, victimhood and the appraisal of personal safety in people with schizophrenia: results from the European Schizophrenia Cohort (EuroSC)

Background Patients with schizophrenia are at increased risk of being victims of violent and non-violent crimes. We have determined how the experience of crime and subjective feelings of safety differ between urban and rural residential areas. Method We analysed data from the European Schizophrenia Cohort (EuroSC), a 2-year follow-up study of 1208 patients in the UK, France and Germany. Subjective safety and a history of victimhood were elicited with Lehman's Quality of Life Inventory. Regression models adjusted the effects of living environment for country, education, employment, financial situation, drug and alcohol abuse, criminal arrests and the level of schizophrenic symptoms. Results Ten per cent of patients were victims of violent and 19% of non-violent crimes. There was no significant relationship between victim status and residential area. However, subjective safety was clearly worse in cities than in rural areas. Aspects of objective and subjective safety were related to different factors: being the victim of violence was most strongly associated with alcohol and drug abuse and with criminal arrests of the patients themselves, whereas impaired subjective safety was most strongly associated with poverty and victimhood experience. Conclusions Although urban living was not associated with increased objective threats to their security, patients did feel more threatened. Such stress and anxiety can be related to concepts of social capital, and may contribute unfavourably to the course of the illness, reflecting the putative role of appraisal in cognitive models of psychosis. Securing patients’ material needs may provide a way to improve subjective safety.
Histopathological evaluation of endometrium in pre and postmenopausal uterine bleeding

Introduction: Abnormal uterine bleeding is most common gynecological presentation in pre and postmenopausal women caused by benign and malignant lesions and infections. Histopathological examination is the gold standard in diagnosing exact cause of this bleeding. Objectives: 1) To detect pattern of endometrium in women having abnormal uterine bleeding in pre and postmenopausal age group. 2) To detect incidence of carcinoma endometrium in this age group. Methods: A retrospective study was conducted of 250 patients more than 40 years of age group presented with abnormal uterine bleeding from January 2011 to June 2014 attending R. D. Gardi medical college hospital Ujjain (M. P ). Histopathology reports of Endometrium were analysed and results were tabulated. Results: Maximum incidence of AUB was found in the age group of 40-42 years premenopausal (38.42%) and 50-52 years in postmenopausal women (43.3%). Menorrhagia was most common bleeding pattern found in proliferative (28.5%) and secretary (28.5%) profile. Postmenopausal bleeding was common in atrophic endometrial profiles (41%) and malignant lesions (100%). Proliferative pattern was most common in age group of 50-54 years (30.3%), secretary in 45-49 years (30.3%), atrophic endometrium in age group 65-69 years (100%), polyp in 60-64years (25%), endometritis (8.9%) in 45-49 years, irregular shedding (21.6%) in 40-44 age group, simple hyperplasia (19.6%) in 45-49 years, endometrial carcinoma (11.7%) in age group of 55-59 years. Conclusion: Sampling of endometrium is a must in all women over the age of 40 years presenting with AUB for exact diagnosis of benign and malignant lesions
Fast Enumeration of Large k-Plexes

K-plexes are a formal yet flexible way of defining communities in networks. They generalize the notion of cliques and are more appropriate in most real cases: while a node of a clique C is connected to all other nodes of C, a node of a k-plex may miss up to k connections. Unfortunately, computing all maximal k-plexes is a gruesome task and state-of-the-art algorithms can only process small-size networks. In this paper we propose a new approach for enumerating large k-plexes in networks that speeds up the search by several orders of magnitude, leveraging on (i) methods for strongly reducing the search space and (ii) efficient techniques for the computation of maximal cliques. Several experiments show that our strategy is effective and is able to increase the size of the networks for which the computation of large k-plexes is feasible from a few hundred to several hundred thousand nodes.
Jointly locating the primary and secondary users in cognitive radio networks

In this paper a local geometry alignment algorithm is presented for locating the primary users (PUs) and Secondary users (SUs) in cognitive radio network. Based on the estimated distance between PUs and SUs for the neighbors within certain communication range, the relative configuration of all the users in the network is obtained initially and is refined finally to get the global position of every user in the network. The localization performance of the proposed approach is compared to multidimensional scaling and principal component analysis. Furthermore the lower bound on error i.e., the Cramer Rao lower bound (CRLB) is also derived to check the performance of the proposed algorithm.
Collagen versus gelatin-coated Dacron versus stretch polytetrafluoroethylene in abdominal aortic bifurcation graft surgery: results of a seven-year prospective, randomized multicenter trial.

BACKGROUND A prospective randomized multicenter trial was performed to compare knitted gelatin-coated Dacron bifurcation grafts, knitted collagen-coated Dacron grafts, and stretch polytetrafluoroethylene (PTFE) grafts. METHODS Between 1991 and 1998, 315 elective patients were randomized by age, gender, diabetes, runoff, indication (aneurysm, aortoiliac occlusive disease), and nicotine consumption at 3 centers of vascular surgery in Austria. The patients received gelatin-coated Dacron (GEL-D) grafts (n = 109), collagen-coated Dacron (COL-D) grafts (n = 100), or stretch PTFE grafts (n = 106). RESULTS No intraoperative deaths occurred. The 30-day mortality was 3%. No difference was found between the 3 graft materials in long-term patency. The primary 5-year patency rates were 92% for GEL-D, 89% for COL-D, and 91% for stretch PTFE (P =.6001). The secondary 5-year patency rates also differed: 97% for GEL-D, 100% for COL-D, and 97% for stretch PTFE (P =.2062). Early occlusions were observed overall in 3% and late occlusions in 5% of patients. When both Dacron grafts were compared collectively with stretch PTFE, a difference was found in infection rate: Dacron 3% (6/209) versus PTFE 0% (0/106); P <. 03. CONCLUSIONS The bifurcation grafts of all 3 materials were comparable in primary and secondary patency rates, incidence of false aneurysms, and rate of perioperative complications. Graft infections were confined to the 2 Dacron grafts and did not occur in stretch PTFE grafts.
PROPOSTA PARA MELHORIA DO PROBLEMA DO IMBALANCE DE CONTÊINERES:

Um dos problemas mais relevantes na logística global de transporte de contêineres é o imbalance gerado por características dos mercados produtores e consumidores.

Signaling mechanisms for chemotaxis

Cells recognize external chemical gradients and translate these environmental cues into amplified intracellular signaling that results in elongated cell shape, actin polymerization toward the leading edge, and movement along the gradient. Mechanisms underlying chemotaxis are conserved evolutionarily from Dictyostelium amoeba to mammalian neutrophils. Recent studies have uncovered several parallel intracellular signaling pathways that crosstalk in chemotaxing cells. Here, we review these signaling mechanisms in Dictyostelium discoideum.

As an application, we obtain a Lie bialgebra from a sub-Poisson bialgebra of the restricted dual of the universal enveloping algebra U(g).
Rôle des canaux calciques Cav3.2 dans les interneurones de la lamina II de la moelle épinière

La douleur est un mecanisme essentiel pour la survie, mais les douleurs chroniques sont souvent invalidantes. Les douleurs de longue duree sont une des premieres causes de consultation medicale, et affectent 20% de la population. Par contre, les traitements actuels sont souvent inefficaces au long cours, avec un ratio benefice/risque faible. Il est ainsi une priorite majeure la recherche des nouveaux agents therapeutiques. Pour ce faire, la comprehension de reseaux impliques dans la douleur est essentielle.Plusieurs etudes ont montre que Cav3.2, un canal calcique a bas seuil, pourrait etre une cible analgesique prometteuse. En fait, Cav3.2 est exprime tout le long de voies douloureuses, au niveau peripherique ainsi qu’au niveau central. Notamment, Cav3.2 est fortement exprime dans la corne dorsale de la moelle epiniere, qui constitue le premier relai d’integration de l’information douloureuse. De plus, grâce a son activation aux potentiels proche du repos, Cav3.2 est bien place pour reguler l’excitabilite neuronale et l’integration synaptique. Au cours de cette these nous avons etudie la distribution de ce canal dans les interneurones de la lamina II de la corne dorsale. Nos resultats montrent que le canal est exprime dans differentes types d’interneurones (~60%), majoritairement excitateurs, mais aussi inhibiteurs. De facon interessante, tous les neurones PKCγ, impliques dans l’allodynie mecanique, expriment le canal Cav3.2. Nous avons ensuite utilise une approche virale pour marquer et etudier les proprietes electrophysiologiques des neurones exprimant Cav3.2, ainsi que pour reprimer de facon specifiques le canal dans la partie lombaire de la moelle epiniere. Nos resultats montrent que Cav3.2 participe dans les rebonds depolarisants sous-liminaires, dans les proprietes des potentiels d’action et dans les profils d’activite electrique de ces neurones. Ainsi, Cav3.2 pourrait jouer un role important dans les etats douloureux au niveau spinal, caracterises par des changements dans l’excitabilite.
Synthesis of Infective Poliovirus in BSC-1 Monkey Cells Enucleated with Cytochalasin B

BSC-1 monkey kidney cells were enucleated by two cycles of centrifugation in the presence of cytochalasin B. The resulting populations contained 99.5 percent enucleated cells. After infection, newly synthesized poliovirus was recovered from the enucleated populations. Final virus yield per enucleated cell was about one-fifth the yield per infected untreated cell
Interleukin-8 Promoter Polymorphism Increases the Risk of Atrophic Gastritis and Gastric Cancer in Japan

Host genetic susceptibility may influence gastric carcinogenesis caused by Helicobacter pylori infection. We aimed to clarify the relationship of interleukin (IL)-8 polymorphism with the risk of atrophic gastritis and gastric cancer. We examined IL-8 −251 T > A, IL-1B −511 C > T, and IL-1RN intron 2 polymorphisms in 252 healthy controls, 215 individuals with atrophic gastritis, and 396 patients with gastric cancer. We also investigated the effect of the IL-8 polymorphism on IL-8 production and histologic degree of gastritis in noncancerous gastric mucosa. Although no correlation was found in the analysis of the IL-1B and IL-1RN polymorphisms, IL-8 −251 A/A genotype held a higher risk of atrophic gastritis [odds ratio (OR), 2.35; 95% confidence interval (CI), 1.12-4.94] and gastric cancer (OR, 2.22; 95% CI, 1.08-4.56) compared with the T/T genotype. We also found that the A/A genotype increased the risk of upper-third location (OR, 3.66; 95% CI, 1.46-9.17), diffuse (OR, 2.79; 95% CI, 1.21-6.39), poorly differentiated (OR, 2.70; 95% CI, 1.14-6.38), lymph node (OR, 2.50; 95% CI, 1.01-6.20), and liver metastasis (OR, 5.63; 95% CI, 1.06-30.04), and p53-mutated (OR, 1.91; 95% CI, 1.13-3.26) subtypes of gastric cancer. The A/A and A/T genotypes were significantly associated with higher levels of IL-8 protein compared with the T/T genotype. Neutrophil infiltration score was significantly higher in the A/A genotype than in the T/T genotype. In conclusion, we showed that the IL-8 −251 T > A polymorphism is associated with higher expression of IL-8 protein, more severe neutrophil infiltration, and increased risk of atrophic gastritis and gastric cancer.

Dietary Intake and Associated Body Weight in Canadian Undergraduate Students Enrolled in Nutrition Education

ABSTRACT The primary purpose of this study was to describe dietary intakes among Canadian undergraduate students enrolled in an Introductory Nutrition course. A secondary objective was to determine food group servings associated with meeting more Dietary Reference Intakes (DRIs) of select nutrients and with a lower body mass index (BMI). Participants (n = 124, 20.7±3.2yrs) provided output from a 3-day dietary record and completed a physical activity/demographics questionnaire. Linear regression showed that the dietary intake associated with meeting the most DRIs included vegetables, fruits, protein foods, and dairy (p = 0.001). Protein foods were a positive predictor and fruit a negative predictor of BMI (p = 0.001 and p = 0.023 respectively). Males consumed more grains (p = 0.001), dairy (p = 0.04), protein foods (p < 0.001), empty calories (p = 0.007) and total calories than females (p < 0.001). A diet characterized by greater intake of vegetables, fruits, protein foods, and dairy was associated with a Canadian undergraduate population meeting the greatest number of nutrient requirements.
