    Full Text Available In Italy, five library associations of national significance function at present. There are special associations of ecclesiastic libraries, prison libraries, architecture libraries and libraries with artistic material. The role of the general national association, covering all types of libraries including documentation centres, is played by the Italian Library Association. It strive for the development of a contemporary Italian library system comparable to international standards, monitors library legislation, promotes education for librarians and keeps the librarians and the broader public informed about the importance of libraries and librarianship for society. The activity and efforts of the association are reflected through their website offering much information and links to similar sites. ILA presents and realises its activities for both, the librarians and the public users. A great deal of actions promoting libraries and the Library Association might be interesting for Slovenia and perhaps transferred to our environment.

  15. Network Consistent Data Association.

    Chakraborty, Anirban; Das, Abir; Roy-Chowdhury, Amit K

    2016-09-01

    Existing data association techniques mostly focus on matching pairs of data-point sets and then repeating this process along space-time to achieve long term correspondences. However, in many problems such as person re-identification, a set of data-points may be observed at multiple spatio-temporal locations and/or by multiple agents in a network and simply combining the local pairwise association results between sets of data-points often leads to inconsistencies over the global space-time horizons. In this paper, we propose a Novel Network Consistent Data Association (NCDA) framework formulated as an optimization problem that not only maintains consistency in association results across the network, but also improves the pairwise data association accuracies. The proposed NCDA can be solved as a binary integer program leading to a globally optimal solution and is capable of handling the challenging data-association scenario where the number of data-points varies across different sets of instances in the network. We also present an online implementation of NCDA method that can dynamically associate new observations to already observed data-points in an iterative fashion, while maintaining network consistency. We have tested both the batch and the online NCDA in two application areas-person re-identification and spatio-temporal cell tracking and observed consistent and highly accurate data association results in all the cases.

Does it matter whether association ‘membership’ is simply an annual payment or a major commitment of time and energy? In this article, we...... use a large survey to explore these questions empirically by focusing on the membership patterns and civic engagement practices of 4,001 citizens drawn from eight suburbs across Greater Melbourne, Australia. Our findings indicate that, while associational intensity is positively related to civic...... engagement, associational scope (the number of group memberships per person), is a more influential determinant of the level of civic and political participation.

    2000-01-01

    The problem of association rule mining has gained considerable prominence in the data mining community for its use as an important tool of knowl-edge discovery from large-scale databases. And there has been a spurt of research activities around this problem. Traditional association rule mining is limited to intra-transaction. Only recently the concept of N-dimensional inter-transaction as-sociation rule (NDITAR) was proposed by H.J. Lu. This paper modifies and extends Lu's definition of NDITAR based on the analysis of its limitations, and the general-ized multidimensional association rule (GMDAR) is subsequently introduced, which is more general, flexible and reasonable than NDITAR.

    Thorndike (1898, 1911) rejected the idea that animal behavior was the consequence of reasoning, and suggested instead that the gradual acquisition of associations formed the basis of behavior-a contention that has had a significant impact on the development of animal learning theory. Despite this, comparative psychology provides a number of examples of behaviors that have been considered to be above and beyond the explanation of associative-, or reinforcement-learning mechanisms. These behaviors have motivated some researchers to propose higher-order cognitive abilities in animals, including (but not limited to) reasoning, sensitivity to ambiguity, and metacognition. However, other authors have questioned this claim, and provided alternative explanations for these behaviors from an associative perspective. With relevant examples, the steps that must be taken in order to overcome an associative explanation of behavior are described. (PsycINFO Database Record PMID:26986019

    Smith, D.J.; Forrest, S. [New Mexico Univ., Albuquerque, NM (United States). Dept. of Computer Science; Perelson, A.S. [Los Alamos National Lab., NM (United States)

    1996-12-31

    The purpose of this paper is to show that immunological memory is an associative and robust memory that belongs to the class of sparse distributed memories. This class of memories derives its associative and robust nature by sparsely sampling the input space and distributing the data among many independent agents. Other members of this class include a model of the cerebellar cortex and Sparse Distributed Memory (SDM). First we present a simplified account of the immune response and immunological memory. Next we present SDM, and then we show the correlations between immunological memory and SDM. Finally, we show how associative recall in the immune response can be both beneficial and detrimental to the fitness of an individual.

    1992-12-01

    Previous research has demonstrated a number of conditions, such as sleep disturbance, fatigue, depression, spastic colon and mitral valve prolapse, associated with fibromyalgia. The present report describes additional symptoms and medical conditions that appear to be associated with the syndrome based on a survey of 554 individuals with fibromyalgia compared with a group of 169 controls. Individuals with fibromyalgia self report a greater incidence of bursitis, chondromalacia, constipation, diarrhea, temporomandibular joint dysfunction, vertigo, sinus and thyroid problems. Symptomatic complaints found statistically more prevalent in fibromyalgia patients included concentration problems, sensory symptoms, swollen glands and tinnitus. Other associations occurring with significant increased frequency were chronic cough, coccygeal and pelvic pain, tachycardia and weakness. Our previous report on inheritance patterns in fibromyalgia was reaffirmed with 12% reporting symptomatic children and 25% reporting symptomatic parents. Of the respondents, 70% noted that their symptoms were aggravated by noise, lights, stress, posture and weather. PMID:1466872

    BACKGROUND: Acromegaly secondary to growth hormone-releasing hormone (GHRH) excess is rare. AIMS\\/CASE DESCRIPTION: We report two patients with acromegaly who were diagnosed with sellar gangliocytomas that were immunopositive for GHRH. Tumour tissue persisted after debulking surgery and in the second case this was associated with persistent growth hormone hypersecretion, successfully suppressed by a somatostatin analogue. CONCLUSIONS: The development of functional pituitary adenomas in association with sellar gangliocytomas is poorly understood. We present a brief discussion of the possible aetiology of these unusual pituitary tumours.

    2005-01-01

    AIDS associated malignancies (ARL) is a major complication associated with AIDS patients upon immunosuppression.Chronically immunocompromised patients have a markedly increased risk of developing lymphoproliferative disease. In the era of potent antiretrovirals therapy (ARV), the malignant complications due to HIV- 1 infection have decreased in developed nations where ARV is administered, but still poses a major problem in developing countries where HIV- 1incidence is high and ARV is still not yet widely available. Even in ARV treated individuals there is a concern that the prolonged survival of many HIV- 1 carriers is likely to eventually result in an increased number of malignancies diagnosed.Malignancies that were found to have high incidence in HIV-infected individuals are Kaposi's sarcoma (KS), Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The incidence of NHL has increased nearly 200 fold in HIV-positive patients, and accounts for a greater percentage of AIDS defining illness in the US and Europe since the advent of HAART therapy. These AIDS related lymphomas are distinct from their counterparts seen in HIV- 1 seronegative patients.For example nearly half of all cases of ARL are associated with the presence of a gamma herpesvirus, Epstein Barr virus (EBV) or human herpesvirus-8 (HHV-8)/Kaposi's sarcoma associated herpesvirus (KSHV). The pathogenesis of ARLs is complex. B-cell proliferation driven by chronic antigenemia resulting in the induction of polyclonal and ultimately monoclonal lymphoproliferation may occur in the setting of severe immunosuppression.

    Kemmann, E; Pasquale, S A; Skaf, R

    1983-02-18

    Data are presented for ten women with anovulation, nine of them with amenorrhea, who have associated carotenemia. Classic explanations for carotenemia in amenorrheic patients have been weight loss or anorexia nervosa, yet carotenemia in our patients appeared to be diet induced. All patients consumed a pure or predominantly vegetarian diet; there was no intake of red meats. Clinical and laboratory data of the patients are presented. The amenorrhea of the patient is consistent with hypothalamic hypogonadotropic anovulation (HHA). It appeared that diet modification not only led to reduction in carotene levels, but also improved the menstrual status. The association of carotenemia and menstrual disorders is reviewed. The possibility that carotenemia is related to the development of HHA is discussed. PMID:6823046

    In a basic associative learning paradigm, learning is said to have occurred when the conditioned stimulus evokes an anticipatory response. This learning is widely believed to depend on the contiguous presentation of conditioned and unconditioned stimulus. However, what it means to be contiguous has not been rigorously defined. Here we examine the empirical bases for these beliefs and suggest an alternative view based on the hypothesis that learning about the temporal relationships between eve...

    A generalization of power associative algebra, called Hom-power associative algebra, is studied. The main result says that a multiplicative Hom-algebra is Hom-power associative if and only if it satisfies two identities of degrees three and four. It generalizes Albert's result that power associativity is equivalent to third and fourth power associativity. In particular, multiplicative right Hom-alternative algebras and non-commutative Hom-Jordan algebras are Hom-power associative.

    Blocking of learning about a conditioned stimulus (the "blocked" cue) occurs when it is trained alongside an additional stimulus (the "blocking" cue) that has been previously presented with the outcome. A number of theories (e.g., N. J. Mackintosh. 1975a. A Theory of Attention: Variations in the Associability of Stimuli With Reinforcement. Psychological Review, 82, 276-298; J. M. Pearce & G. Hall. 1980. A Model for Pavlovian Learning: Variation in the Effectiveness of Conditioned But Not Unconditioned Stimuli. Psychological Review, 87, 532-552) account for this attenuation in learning by proposing that attention paid to the blocked cue is restricted. In three experiments, we examined the associability of both blocked and blocking cues. In Experiment 1, rats were trained with a blocking protocol before being given a test discrimination composed of two components; one of these components required the use of the previously blocked cue as a discriminative stimulus, and the other component was soluble by using the blocking cue. To our surprise, the component that depended on the blocked cue was more readily solved than the component dependent on the blocking cue. The results of Experiments 2 and 3 suggest that this is due to the quantity of exposure that each stimulus received during initial training. Implications for theories of blocking, and more widely associative learning, are discussed. PMID:23668185

  14. Scoliosis Associated With Syringomyelia

    2007-01-01

    Full Text Available Introduction: The differential diagnosis of idiopathic and syringomyelia associated scoliosis is important because corrective surgery for scoliosis associated with syringomyelia prior to management of syringomyelia can be dangerous. There are important imaging indicators for diagnosis of syringomyelia associated with scoliosis. A few of these indicators have been assessed in our study. Methods: A retrospective descriptive study including 38 patients with both scoliosis and syringomyelia was performed at the Shafa Yahyaeian center. Standard scoliosis series radiographs and MRI of all patients were studied. The type of scoliosis, location and magnitude of deformity, kyphosis or lordosis in the sagittal plane, location and size of syrinx were assessed. Results: Thoracic kyphosis was present in 94.7% of patients. 37% of patients had scoliosis with convexity to left. Arnold –chiari malformation was present in 36% and cord tethering in 21% of patients. The locations of syrinx were as follows: 47.4%cervical, 44.6 thoracic, 2.7% lumbar and 5.3% were holocord. Conclusion: Kyphosis, abscence of lordosis in sagittal plane, progressive scoliosis and scoliosis with convexity to left are atypical findings and could be indicators of the presence of syringomyelia. If these indicators are present, a diagnosis of idiopathic scoliosis should be made with caution.

    2016-07-01

    People often fail to follow through on good intentions. While limited self-control is frequently the culprit, another cause is simply forgetting to enact intentions when opportunities arise. We introduce a novel, potent approach to facilitating follow-through: the reminders-through-association approach. This approach involves associating intentions (e.g., to mail a letter on your desk tomorrow) with distinctive cues that will capture attention when you have opportunities to act on those intentions (e.g., Valentine's Day flowers that arrived late yesterday, which are sitting on your desk). We showed that cue-based reminders are more potent when the cues they employ are distinctive relative to (a) other regularly encountered stimuli and (b) other stimuli encountered concurrently. Further, they can be more effective than written or electronic reminder messages, and they are undervalued and underused. The reminders-through-association approach, developed by integrating and expanding on past research on self-control, reminders, and prospective memory, can be a powerful tool for policymakers and individuals.

  17. VACTERL/VATER Association

    Directory of Open Access Journals (Sweden)

    Solomon Benjamin D

    2011-08-01

    Full Text Available Abstract VACTERL/VATER association is typically defined by the presence of at least three of the following congenital malformations: vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities. In addition to these core component features, patients may also have other congenital anomalies. Although diagnostic criteria vary, the incidence is estimated at approximately 1 in 10,000 to 1 in 40,000 live-born infants. The condition is ascertained clinically by the presence of the above-mentioned malformations; importantly, there should be no clinical or laboratory-based evidence for the presence of one of the many similar conditions, as the differential diagnosis is relatively large. This differential diagnosis includes (but is not limited to Baller-Gerold syndrome, CHARGE syndrome, Currarino syndrome, deletion 22q11.2 syndrome, Fanconi anemia, Feingold syndrome, Fryns syndrome, MURCS association, oculo-auriculo-vertebral syndrome, Opitz G/BBB syndrome, Pallister-Hall syndrome, Townes-Brocks syndrome, and VACTERL with hydrocephalus. Though there are hints regarding causation, the aetiology has been identified only in a small fraction of patients to date, likely due to factors such as a high degree of clinical and causal heterogeneity, the largely sporadic nature of the disorder, and the presence of many similar conditions. New genetic research methods offer promise that the causes of VACTERL association will be better defined in the relatively near future. Antenatal diagnosis can be challenging, as certain component features can be difficult to ascertain prior to birth. The management of patients with VACTERL/VATER association typically centers around surgical correction of the specific congenital anomalies (typically anal atresia, certain types of cardiac malformations, and/or tracheo-esophageal fistula in the immediate postnatal period, followed by long-term medical management of sequelae of

    We report two cases of perindopril-associated pneumonitis with typical drug-induced clinical features. In the first case, biopsies showed granulomatous sarcoid-like lesions; in the second, bronchial wall eosinophil infiltratf2p4was reported with increased blood eosinophil count. In these two cases, improvement was obtained by withdrawal of the drug and was completed with steroids. All other causes were ruled out. Angiotensin-converting enzyme inhibitor (ACEI)-induced pneumonitis is still rare but has to be recognized as a real side-effect. PMID:8804953

    The fourth case in the literature is presented of a patient with the rare association of hyperparathyroidism and osteosarcoma. A 56-year-old woman presented with hyperparathyroidism and a lesion in the tibia. Initial diagnosis was brown tumor. Histology, however, revealed osteosarcoma, and the patient was treated accordingly. The experimental induction of osteosarcoma by parathormone in rodent studies makes this finding alarming, considering the increasing use of parathormone in the treatment of osteoporosis. The mechanism by which osteosarcoma is induced in humans cannot be explained based on current knowledge of mechanisms of action of parathyroid hormone. (orig.)

    Full Text Available Information concerning the presence of stink bugs in blackberry (Rubus spp. in Brazil is sparse. This study aimed to identify the stink bug species associated with blackberry, to establish the daily dynamics and evaluate the fruits damage. The experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, in blackberry orchard. Presence and evaluations of stink bugs were done weekly through visual and sweeping samplings at different day times. Five species of pentatomids were identified: Piezodorus guildinii, Nezara viridula, Euschistus heros, Dichelops furcatus and Edessa meditabunda. The bugs attack the drupelets producing a dark brown spot and wrinkled berries.

  1. Associative asymmetry of compound words.

    Caplan, Jeremy B; Boulton, Kathy L; Gagné, Christina L

    2014-07-01

    Early verbal-memory researchers assumed participants represent memory of a pair of unrelated items with 2 independent, separately modifiable, directional associations. However, memory for pairs of unrelated words (A-B) exhibits associative symmetry: a near-perfect correlation between accuracy on forward (A →?) and backward (?← B) cued recall. This was viewed as arguing against the independent-associations hypothesis and in favor of the hypothesis that associations are remembered as holistic units. Here we test the Holistic Representation hypothesis further by examining cued recall of compound words. If we suppose preexisting words are more unitized than novel associations, the Holistic Representation hypothesis predicts compound words (e.g., ROSE BUD) will have a higher forward-backward correlation than novel compounds (e.g., BRIEF TAX). We report the opposite finding: Compound words, as well as noncompound words, exhibited less associative symmetry than novel compounds. This challenges the Holistic Representation account of associative symmetry. Moreover, preexperimental associates (positional family size) influenced associative symmetry-but asymmetrically: Increasing family size of the last constituent increasing decoupled forward and backward recall, but family size of the 1st constituent had no such effect. In short, highly practiced, meaningful associations exhibit associative asymmetry, suggesting associative symmetry is not diagnostic of holistic representations but, rather, is a characteristic of ad hoc associations. With additional learning, symmetric associations may be replaced by directional, independently modifiable associations as verbal associations become embedded within a rich knowledge structure.

  2. Associative learning in invertebrates.

    2015-05-01

    This work reviews research on neural mechanisms of two types of associative learning in the marine mollusk Aplysia, classical conditioning of the gill- and siphon-withdrawal reflex and operant conditioning of feeding behavior. Basic classical conditioning is caused in part by activity-dependent facilitation at sensory neuron-motor neuron (SN-MN) synapses and involves a hybrid combination of activity-dependent presynaptic facilitation and Hebbian potentiation, which are coordinated by trans-synaptic signaling. Classical conditioning also shows several higher-order features, which might be explained by the known circuit connections in Aplysia. Operant conditioning is caused in part by a different type of mechanism, an intrinsic increase in excitability of an identified neuron in the central pattern generator (CPG) for feeding. However, for both classical and operant conditioning, adenylyl cyclase is a molecular site of convergence of the two signals that are associated. Learning in other invertebrate preparations also involves many of the same mechanisms, which may contribute to learning in vertebrates as well. PMID:25877219

    To analyze the SACY (Search for Associations Containing Young stars) survey we developed a method to find young associations and to define their high probability members. These bona fide members enable to obtain the kinematical and the physical properties of each association in a proper way. Recently we noted a concentration in the UV plane and we found a new association we are calling ASYA (All Sky Young Association) for its overall distribution in the sky with a total of 38 bonafide members and an estimated age of 110 Myr, the oldest young association found in the SACY survey. We present here its kinematical, space and Li distributions and its HR diagram.

    Full Text Available Transfusion associated circulatory overload (TACO is an established, but grossly under diagnosed and underreported complication of blood transfusion. We present the case of a 46-year-old diabetic and hypertensive patient admitted to our hospital for recurrent episodes of urinary retention. Over initial 3 days of the admission, the patient received multiple units of packed red blood cells (RBC and fresh frozen plasma, uneventfully. However, the patient developed signs and symptoms suggestive of TACO with only small amount of the 4 th unit of RBC. The patient had to be shifted to the Intensive Care Unit for further management of this complication. Etiology of TACO is more complex than a mere circulatory overload and is still not completely understood. TACO leads to a prolonged hospital stay and morbidity in the patients developing this complication. TACO thus needs to be suspected in patients at risk for this complication.

    The intersecting HIV and Tuberculosis epidemics in countries with a high disease burden of both infections pose many challenges and opportunities. For patients infected with HIV in high TB burden countries, the diagnosis of TB, ARV drug choices in treating HIV-TB coinfected patients, when to initiate ARV treatment in relation to TB treatment, managing immune reconstitution, minimising risk of getting infected with TB and/or managing recurrent TB, minimizing airborne transmission, and infection control are key issues. In addition, given the disproportionate burden of HIV in women in these settings, sexual reproductive health issues and particular high mortality rates associated with TB during pregnancy are important. The scaleup and resource allocation to access antiretroviral treatment in these high HIV and TB settings provide a unique opportunity to strengthen both services and impact positively in meeting Millennium Development Goal 6.

Clonazepam was prescribed for myoclonus disorder two weeks prior to her hospitalization. Subsequently, she was hospitalized for neutropenic fever with thrombocytopenia and worsening anemia. Bone marrow examination demonstrated a markedly hypocellular marrow (10-20% total cellularity. Clonazepam was discontinued, with gradual improvement of thrombocytopenia, and neutropenia in 1-2 weeks. To our knowledge, this is the first reported case of pancytopenia associated with clonazepam. We recommend patients taking clonazepam to be monitored with regular complete blood count to check for clinically significant pancytopenia or thrombocytopenia.

    V.G. Kupriyanov

    2016-09-01

    Full Text Available Non-commutativity and non-associativity are quite natural in string theory. For open strings it appears due to the presence of non-vanishing background two-form in the world volume of Dirichlet brane, while in closed string theory the flux compactifications with non-vanishing three-form also lead to non-geometric backgrounds. In this paper, working in the framework of deformation quantization, we study the violation of associativity imposing the condition that the associator of three elements should vanish whenever each two of them are equal. The corresponding star products are called alternative and satisfy important for physical applications properties like the Moufang identities, alternative identities, Artin's theorem, etc. The condition of alternativity is invariant under the gauge transformations, just like it happens in the associative case. The price to pay is the restriction on the non-associative algebra which can be represented by the alternative star product, it should satisfy the Malcev identity. The example of nontrivial Malcev algebra is the algebra of imaginary octonions. For this case we construct an explicit expression of the non-associative and alternative star product. We also discuss the quantization of Malcev–Poisson algebras of general form, study its properties and provide the lower order expression for the alternative star product. To conclude we define the integration on the algebra of the alternative star products and show that the integrated associator vanishes.

  1. Associative concept learning in animals.

    Zentall, Thomas R; Wasserman, Edward A; Urcuioli, Peter J

    2014-01-01

    Nonhuman animals show evidence for three types of concept learning: perceptual or similarity-based in which objects/stimuli are categorized based on physical similarity; relational in which one object/stimulus is categorized relative to another (e.g., same/different); and associative in which arbitrary stimuli become interchangeable with one another by virtue of a common association with another stimulus, outcome, or response. In this article, we focus on various methods for establishing associative concepts in nonhuman animals and evaluate data documenting the development of associative classes of stimuli. We also examine the nature of the common within-class representation of samples that have been associated with the same reinforced comparison response (i.e., many-to-one matching) by describing manipulations for distinguishing possible representations. Associative concepts provide one foundation for human language such that spoken and written words and the objects they represent become members of a class of interchangeable stimuli. The mechanisms of associative concept learning and the behavioral flexibility it allows, however, are also evident in the adaptive behaviors of animals lacking language.

    Kandinsky proposed a correspondence theory that suggests associations between specific colors and shapes (i.e., circle-blue, square-red, triangle-yellow). Makin and Wuerger tested the theory using the Implicit Association Test (IAT) and did not find clear evidence for Kandinsky's color-shape associations among British participants. In the present study, we first replicated the previous study among Japanese participants and found similar results to those of Makin and Wuerger, showing little support for Kandinsky's theory. In the subsequent experiment, we tested another set of color-shape associations that had been revealed by using an explicit matching method (circle-red, square-blue, triangle-yellow) in Japanese participants. The IAT tests showed that response times were significantly faster when circle-red, square-blue, and triangle-yellow combinations were mapped onto the same response key, rather than different key combinations, indicating that these color-shape combinations were encoded. These results provide the first empirical evidence that color-shape associations can be measured by indirect behavioral methods, and in particular, Japanese people's color-shape associations (circle-red, square-blue, triangle-yellow) can be observed by both direct and indirect experimental methods.

    Neuromyelitis optica (NMO) is an autoimmune disorder diagnosed by an elongated spinal cord lesion associated with unilateral or bilateral optic neuritis and anti-aquaporin 4 (AQP4) antibodies in the serum. It is triggered by or associated with several autoimmune diseases, but not with sarcoidosis. It responds to immunomodulators better than to steroid treatment. Sarcoidosis is an autoimmune disorder which manifests as non-caseating granulomas, usually in the lung parenchyma, but also in other tissues, including the brain. The involvement of the central nervous system in neurosarcoidosis differs considerably from that in neuromyelitis optica and the association of these two diseases concurrently in the same patient is unusual.

    1985-01-01

    Acute marijuana effects on associative processes involved in long-term memory retrieval were studied. Results were partially consistent with expectations based on previous subjective reports that marijuana promotes more uncommon associations. Marijuana altered responses when people gave as many examples of a specified category (e.g., CLOTHING) as they could for 2 min, and when they gave an example of a specified category beginning with a specified letter (e.g., WEAPON - G). Reaction time in the latter task and in prior studies was not altered in the expected manner, a finding problematic for some theoretic interpretations of marijuana's effects on associative processes.

    2002-03-01

    Discovering interesting, implicit knowledge and general relationships in geographic information databases is very important to understand and use these spatial data. One of the methods for discovering this implicit knowledge is mining spatial association rules. A spatial association rule is a rule indicating certain association relationships among a set of spatial and possibly non-spatial predicates. In the mining process, data is organized in a hierarchical manner. However, in real-world applications it may not be possible to construct a crisp structure for this data, instead some fuzzy structures should be used. Fuzziness, i.e. partial belonging of an item to more than one sub-item in the hierarchy, could be applied to the data itself, and also to the hierarchy of spatial relations. This paper shows that, strong association rules can be mined from large spatial databases using fuzzy concept and spatial relation hierarchies.

    2014-01-01

    BACKGROUND Health care-associated infections (HAIs) are the most common noncardiac complications after cardiac surgery and are associated with increased morbidity and mortality. Current information about their economic burden is limited. OBJECTIVES To determine the cost associated with major types of HAIs during the first 2 months after cardiac surgery. METHODS Prospectively collected data from a multicenter observational study of the Cardiothoracic Surgery Clinical Trials Network, in which patients were monitored for infections for 65 days after surgery, were merged with related financial data, routinely collected by the University HealthSystem Consortium. Incremental length of stay (LOS) and cost associated with HAIs were estimated using generalized linear models, adjusting for patient demographics, clinical history, baseline laboratory values, and surgery type. RESULTS Among 4,320 cardiac surgery patients, mean age of 64 ± 13 years, 119 (2.8%) experienced a major HAI during the index hospitalization. The most common HAIs were pneumonia (48%), sepsis (20%) and C. Difficile colitis (18%). On average, the estimated incremental cost associated with a major HAI was nearly $38,000, of which 47% was related to intensive care unit services. The incremental LOS was 14 days. Overall, there were 849 readmissions, among these, 8.7% were attributed to major HAIs. The cost of readmissions due to major HAI was on average nearly three times as much as readmissions not related to HAI. CONCLUSIONS Hospital cost, length of stay, and readmissions are strongly associated with HAIs. These associations suggest the potential for large reductions in costs if HAIs following cardiac surgery can be reduced. PMID:25572505

    2001-12-01

    In the present study we introduce a novel task for the quantitative assessment of both originality and speed of individual associations. This 'BAG' (Bridge-the-Associative-Gap) task was used to investigate the relationships between creativity and paranormal belief. Twelve strong 'believers' and 12 strong 'skeptics' in paranormal phenomena were selected from a large student population (n > 350). Subjects were asked to produce single-word associations to word pairs. In 40 trials the two stimulus words were semantically indirectly related and in 40 other trials the words were semantically unrelated. Separately for these two stimulus types, response commonalities and association latencies were calculated. The main finding was that for unrelated stimuli, believers produced associations that were more original (had a lower frequency of occurrence in the group as a whole) than those of the skeptics. For the interpretation of the result we propose a model of association behavior that captures both 'positive' psychological aspects (i.e., verbal creativity) and 'negative' aspects (susceptibility to unfounded inferences), and outline its relevance for psychiatry. This model suggests that believers adopt a looser response criterion than skeptics when confronted with 'semantic noise'. Such a signal detection view of the presence/absence of judgments for loose semantic relations may help to elucidate the commonalities between creative thinking, paranormal belief and delusional ideation.

  5. Weak associativity and deformation quantization

    CERN Document Server

    Kupriyanov, V G

    2016-01-01

    Non-commutativity is quite natural in string theory. For open strings it appears due to the presence of non-vanishing background two-form in the world volume of Dirichlet brane, while in closed string theory the flux compactifications with non-vanishing three-form also lead to non-commutativity. Except for some specific cases, like the constant $B$-field in open strings, the string coordinates are not only non-commutative, but also non-associative. It manifests the non-geometric nature of the consistent string vacua. The aim of this paper is to study the mathematical tools necessary to deal with non-associativity in physics. Working in the framework of deformation quantization we admit non-associative star products, but keep the violation of associativity under control. We require that the star associator of three functions should vanish whenever each two of them are iqual. Such a star product is called alternative. This condition imposes the restriction on non-associative algebras, the star commutator should...

  6. Family-based association tests for genomewide association scans.

    Chen, Wei-Min; Abecasis, Goncalo R

    2007-11-01

    With millions of single-nucleotide polymorphisms (SNPs) identified and characterized, genomewide association studies have begun to identify susceptibility genes for complex traits and diseases. These studies involve the characterization and analysis of very-high-resolution SNP genotype data for hundreds or thousands of individuals. We describe a computationally efficient approach to testing association between SNPs and quantitative phenotypes, which can be applied to whole-genome association scans. In addition to observed genotypes, our approach allows estimation of missing genotypes, resulting in substantial increases in power when genotyping resources are limited. We estimate missing genotypes probabilistically using the Lander-Green or Elston-Stewart algorithms and combine high-resolution SNP genotypes for a subset of individuals in each pedigree with sparser marker data for the remaining individuals. We show that power is increased whenever phenotype information for ungenotyped individuals is included in analyses and that high-density genotyping of just three carefully selected individuals in a nuclear family can recover >90% of the information available if every individual were genotyped, for a fraction of the cost and experimental effort. To aid in study design, we evaluate the power of strategies that genotype different subsets of individuals in each pedigree and make recommendations about which individuals should be genotyped at a high density. To illustrate our method, we performed genomewide association analysis for 27 gene-expression phenotypes in 3-generation families (Centre d'Etude du Polymorphisme Humain pedigrees), in which genotypes for ~860,000 SNPs in 90 grandparents and parents are complemented by genotypes for ~6,700 SNPs in a total of 168 individuals. In addition to increasing the evidence of association at 15 previously identified cis-acting associated alleles, our genotype-inference algorithm allowed us to identify associated alleles at 4

    Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

    We use appropriately defined short-ranged reference models of liquid water to clarify the different roles local hydrogen bonding, van der Waals attractions, and long-ranged electrostatic interactions play in the solvation and association of apolar solutes in water. While local hydrogen bonding interactions dominate hydrophobic effects involving small solutes, longer-ranged electrostatic and dispersion interactions are found to be increasingly important in the description of interfacial structure around large solutes. The hydrogen bond network sets the solute length scale at which a crossover in solvation behavior between these small and large length scale regimes is observed. Unbalanced long-ranged forces acting on interfacial water molecules are also important in hydrophobic association, illustrated here by analysis of the association of model methane and buckminsterfullerene solutes.

    2013-01-01

    Observational calculi were introduced in the 1960’s as a tool of logic of discovery. Formulas of observational calculi correspond to assertions on analysed data. Truthfulness of suitable assertions can lead to acceptance of new scientific hypotheses. The general goal was to automate the process of discovery of scientific knowledge using mathematical logic and statistics. The GUHA method for producing true formulas of observational calculi relevant to the given problem of scientific discovery was developed. Theoretically interesting and practically important results on observational calculi were achieved. Special attention was paid to formulas - couples of Boolean attributes derived from columns of the analysed data matrix. Association rules introduced in the 1990’s can be seen as a special case of such formulas. New results on logical calculi and association rules were achieved. They can be seen as a logic of association rules. This can contribute to solving contemporary challenging problems of data minin...

Association and some other positive dependence notions were introduced in 1966 and 1967 but received little attention from the probabilistic and statistics community. The interest in these dependence notions increased in the last 15 to 20 years, and many asymptotic results were proved and improved. Despite this increased interest, characterizations and results remained essentially scattered in the literature published in different journals. The goal of this book is to bring together the bulk of these results, presenting

    Obesity has increased dramatically in the United States over the last several decades, with approximately 40% of pregnant women now considered overweight or obese. Obesity has been shown to be associated with numerous poor pregnancy outcomes, including increased rates of preeclampsia, gestational diabetes, fetal macrosomia, stillbirth, postterm pregnancy, and increased rates of cesarean delivery. Many of these complications have been found to increase even further with increasing body mass index in a dose-response fashion. In this review, the association of obesity with maternal, fetal, and pregnancy outcomes is discussed as are the recommendations for caring for the obese gravida.

    Science.gov (United States)

    Dietz, W

    1991-01-01

    Childhood obesity is associated with host factors that enhance susceptibility and environmental factors that increase food intake and decrease energy expenditure. Obese children underreport food intake and probably consume more food to maintain their weight at increased levels. Prevalence of obesity is related to family variables, including parental obesity, family size and age, and socioeconomic status. Television viewing is strongly associated with the prevalence of obesity through its impact on food intake and activity. How these environmental variables are behaviorally interrelated to the genesis of obesity is unclear.

  11. Antibiotic associated diarrhoea: Infectious causes

    Directory of Open Access Journals (Sweden)

    Ayyagari A

    2003-01-01

    Full Text Available Nearly 25% of antibiotic associated diarrhoeas (AAD is caused by Clostridium difficile, making it the commonest identified and treatable pathogen. Other pathogens implicated infrequently include Clostridium perfringens, Staphylococcus aureus, Klebsiella oxytoca, Candida spp. and Salmonella spp. Most mild cases of AAD are due to non-infectious causes which include reduced break down of primary bile acids and decrease metabolism of carbohydrates, allergic or toxic effects of antibiotic on intestinal mucosa and pharmacological effect on gut motility. The antibiotics most frequently associated with C. difficile associated diarrhoea are clindamycin, cephalosporin, ampicillin and amoxicillin. Clinical presentation may vary from mild diarrhoea to severe colitis and pseudomembranous colitis associated with high morbidity and mortality. The most sensitive and specific diagnostic test for C. difficile infection is tissue culture assay for cytotoxicity of toxin B. Commercial ELISA kits are available. Though less sensitive, they are easy to perform and are rapid. Withdrawal of precipitating antibiotic is all that is needed for control of mild to moderate cases. For severe cases of AAD, oral metronidazole is the first line of treatment, and oral vancomycin is the second choice. Probiotics have been used for recurrent cases.

  12. A PROPOSAL OF FUZZY MULTIDIMENSIONAL ASSOCIATION RULES

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Association rules that involve two or more dimensions or predicates can be referred as multidimensional association rules. Rather than searching for frequent itemsets (as is done in mining single-dimensional association rules, in multidimensional association rules, we search for frequent predicate sets. In general, there are two types of multidimensional association rules, namely interdimension association rules and hybrid-dimension association rules. Interdimension association rules are multidimensional association rules with no repeated predicates. This paper introduces a method for generating interdimension association rules. A more meaningful association rules can be provided by generalizing crisp value of attributes to be fuzzy value. To generate the multidimensional association rules implying fuzzy value, this paper introduces an alternative method for mining the rules by searching for the predicate sets.

    Snow, P

    2002-01-01

    Cox's Theorem is a widely cited motivation for probabilistic models of uncertain belief. The theorem relates the associativity of the logical connectives to that of the arithmetic operations of probability. Recent questions about the correctness of Cox's Theorem have been resolved, but there are new questions about one functional equation used by Cox in 1946. This equation is missing from his later work. Advances in knowledge since 1946 and changes in Cox's research interests explain the equation's disappearance. Other associativity-based motivations avoid functional equations altogether, and so may be more transparently applied to finite domains and discrete beliefs. A discrete counterpart of Cox's Theorem can be assembled from results that have been in the literature since 1959. PMID:18238098

    2009-12-01

    Waardenburg syndrome (WS) is a rare autosomal dominant condition characterised by sensorineural hearing loss, in conjunction with pigmentary abnormalities and defects of the neural crest-derived tissues. Depending on the additional phenotypic characteristics, WS is classified into four types, viz. WS1, WS2, WS3 and WS4. We report a 45-day-old male infant with WS1, who presented with inspiratory stridor associated with difficulty in respiration. Direct flexible laryngoscopic examination during evaluation confirmed laryngomalacia as the cause of the symptoms. The baby was managed conservatively and was discharged with appropriate advice to the mother, including the need for evaluation at regular intervals. There was gradual improvement in his symptoms, and by one year of age, he was completely symptom free. To our knowledge, laryngomalacia as a part of WS has not been documented to date in the English literature. We also briefly discussed the probable embryological basis for the observed association.

  16. Radiation-Associated Kidney Injury

    International Nuclear Information System (INIS)

    The kidneys are the dose-limiting organs for radiotherapy to upper abdominal cancers and during total body irradiation. The incidence of radiotherapy-associated kidney injury is likely underreported owing to its long latency and because the toxicity is often attributed to more common causes of kidney injury. The pathophysiology of radiation injury is poorly understood. Its presentation can be acute and irreversible or subtle, with a gradual progressive dysfunction over years. A variety of dose and volume parameters have been associated with renal toxicity and are reviewed to provide treatment guidelines. The available predictive models are suboptimal and require validation. Mitigation of radiation nephropathy with angiotensin-converting enzyme inhibitors and other compounds has been shown in animal models and, more recently, in patients.

    We report a case of right chylothorax associated with physical abuse in a 10-month-old boy who presented with respiratory decompensation. Chylothorax was improved by thoracic drainage and nutrition management, such as fasting followed by medium-chain triglyceride milk. Chest computed tomography on admission showed bilateral old rib fractures. Accordingly, physical abuse was suspected. Chylothorax of unknown cause in infancy, especially in those with coexisting rib fractures, must be scrutinized for child abuse. PMID:26388541

    Introduction and objective: Psoriasis is a chronic skin disease with a high impact on self-esteem and patients’ health-related quality of life. In the last decades some studies have pointed out mental disorders associated with psoriasis and the etiopathogenic mechanisms behind that co-existence. This work compiles psychopathology associated with psoriasis and further analyzes the etiopathogenesis of psoriasis and mental disorders. Methods: A systematic review of the literature was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and using the “5S” levels of organization of evidence from healthcare research, as previously described. Results: Psoriasis is linked with many mental disorders, both in the psychotic and neurotic sprectrum. Chronic stress diminishes hypothalamic-pituitary-adrenal axis and upregulates sympathetic-adrenal-medullary responses, stimulating pro-inflammatory cytokines. Then, it maintains and exacerbates psoriasis and some of its mental disorders. High levels of pro-inflammatory cytokines connect psoriasis, psychiatric conditions, and other comorbidities of psoriasis (such as atherosclerosis) within a vicious cycle. Furthermore, the etiopathogenesis of the link between each psychiatric comorbidity and psoriasis has its own subtleties, including the cooccurrence of other comorbidities, the parts of the body affected by psoriasis, treatments, and biological and psychosocial factors. Conclusion: The study of psychopathology can amplify our understanding about the etiopathogenesis of psoriasis and associated mental disorders. Patients would benefit from a psychodermatologic approach. The adequate treatment should take into account the mental disorders associated with psoriasis as well as the circumstances under which they occur.

  3. Ion association in natural brines

    Science.gov (United States)

    Truesdell, A.H.; Jones, B.F.

    1969-01-01

    Natural brines, both surface and subsurface, are highly associated aqueous solutions. Ion complexes in brines may be ion pairs in which the cation remains fully hydrated and the bond between the ions is essentially electrostatic, or coordination complexes in which one or more of the hydration water molecules are replaced by covalent bonds to the anion. Except for Cl-, the major simple ions in natural brines form ion pairs; trace and minor metals in brines form mainly coordination complexes. Limitations of the Debye-Hu??ckel relations for activity coefficients and lack of data on definition and stability of all associated species in concentrated solutions tend to produce underestimates of the degree of ion association, except where the brines contain a very high proportion of Cl-. Data and calculations on closed basin brines of highly varied composition have been coupled with electrode measurements of single-ion activities in an attempt to quantify the degree of ion association. Such data emphasize the role of magnesium complexes. Trace metal contents of closed basin brines are related to complexes formed with major anions. Alkaline sulfo- or chlorocarbonate brines (western Great Basin) carry significant trace metal contents apparently as hydroxides or hydroxy polyions. Neutral high chloride brines (Bonneville Basin) are generally deficient in trace metals. With a knowledge of the thermodynamic properties of a natural water, many possible reactions with other phases (solids, gases, other liquids) may be predicted. A knowledge of these reactions is particularly important in the study of natural brines which may be saturated with many solid phases (silicates, carbonates, sulfates, etc.), which may have a high pH and bring about dissolution of other phases (silica, amphoteric hydroxides, CO2, etc.), and which because of their high density may form relatively stable interfaces with dilute waters. ?? 1969.

    APL provides convenient associative data manipulation functions in a high level language. Six statements were added to PL/1 via a preprocessor: CREATE, INSERT, FIND, FOR EACH, REMOVE, and DELETE. They allow complete control of all data base operations. During execution, data base management programs perform the functions required to support the APL language. VAAM is the data base management system designed to support the APL language. APL/VAAM is used by CADANCE, an interactive graphic computer system. VAAM is designed to support heavily referenced files. Virtual memory files, which utilize the paging mechanism of the operating system, are used. VAAM supports a full network data structure. The two basic blocks in a VAAM file are entities and sets. Entities are the basic information element and correspond to PL/1 based structures defined by the user. Sets contain the relationship information and are implemented as arrays.

    Currently, neuropsychological impairment among HIV+ patients on antiretroviral therapy leads to a reduction in the quality of life and it is an important challenge due to the high prevalence of HIV-associated neurocognitive disorders and its concomitant consequences in relation to morbidity and mortality- including those HIV+ patients with adequate immunological and virological status. The fact that the virus is established in CNS in the early stages and its persistence within the CNS can help us to understand HIV-related brain injury even when highly active antiretroviral therapy is effective. The rising interest in HIV associated neurocognitive disorders has let to development new diagnostic tools, improvement of the neuropsychological tests, and the use of new biomarkers and new neuroimaging techniques that can help the diagnosis. Standardization and homogenization of neurocognitive tests as well as normalizing and simplification of easily accessible tools that can identify patients with increased risk of cognitive impairment represent an urgent requirement. Future efforts should also focus on diagnostic keys and searching for useful strategies in order to decrease HIV neurotoxicity within the CNS. PMID:25945248

    Craniosynostosis is defined as the premature fusion of one or more of the cranial sutures. It leads not only to secondary distortion of skull shape but to various complications including neurologic, ophthalmic and respiratory dysfunction. Craniosynostosis is very heterogeneous in terms of its causes, presentation, and management. Both environmental factors and genetic factors are associated with development of craniosynostosis. Nonsyndromic craniosynostosis accounts for more than 70% of all cases. Syndromic craniosynostosis with a certain genetic cause is more likely to involve multiple sutures or bilateral coronal sutures. FGFR2, FGFR3, FGFR1, TWIST1 and EFNB1 genes are major causative genes of genetic syndromes associated with craniosynostosis. Although most of syndromic craniosynostosis show autosomal dominant inheritance, approximately half of patients are de novo cases. Apert syndrome, Pfeiffer syndrome, Crouzon syndrome, and Antley-Bixler syndrome are related to mutations in FGFR family (especially in FGFR2), and mutations in FGFRs can be overlapped between different syndromes. Saethre-Chotzen syndrome, Muenke syndrome, and craniofrontonasal syndrome are representative disorders showing isolated coronal suture involvement. Compared to the other types of craniosynostosis, single gene mutations can be more frequently detected, in one-third of coronal synostosis patients. Molecular diagnosis can be helpful to provide adequate genetic counseling and guidance for patients with syndromic craniosynostosis. PMID:27226847

    A widespread epidemic of Zika virus (ZIKV) infection was reported in 2015 in South and Central America and the Caribbean. A major concern associated with this infection is the apparent increased incidence of microcephaly in fetuses born to mothers infected with ZIKV. In this report, we describe the case of an expectant mother who had a febrile illness with rash at the end of the first trimester of pregnancy while she was living in Brazil. Ultrasonography performed at 29 weeks of gestation revealed microcephaly with calcifications in the fetal brain and placenta. After the mother requested termination of the pregnancy, a fetal autopsy was performed. Micrencephaly (an abnormally small brain) was observed, with almost complete agyria, hydrocephalus, and multifocal dystrophic calcifications in the cortex and subcortical white matter, with associated cortical displacement and mild focal inflammation. ZIKV was found in the fetal brain tissue on reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay, with consistent findings on electron microscopy. The complete genome of ZIKV was recovered from the fetal brain.

    Parallelograms are one of the basic building blocks in two-dimensional tiling. They have important applications in a wide variety of science and engineering fields, such as wireless communication networks, urban transportation, operations research, etc. Different from rectangles and squares, the coordinates of a random point in parallelograms are no longer independent. As a case study of parallelograms, the explicit probability density functions of the random Euclidean distances associated with rhombuses are given in this report, when both endpoints are randomly distributed in 1) the same rhombus, 2) two parallel rhombuses sharing a side, and 3) two rhombuses having a common diagonal, respectively. The accuracy of the distance distribution functions is verified by simulation, and the correctness is validated by a recursion and a probabilistic sum. The first two statistical moments of the random distances, and the polynomial fit of the density functions are also given in this report for practical uses.

    Planctomycetes associated with 12 macroalgae from the north coast of Portugal were isolated, using an improved method. A total of 138 isolates were found to comprise 10 operational taxonomic units (OTUs), with 65% of the strains being closely related to the species Rhodopirellula baltica. The other strains are probably new species or genera related to Rhodopirellula, Blastopirellula and Planctomyces. Some of the OTUs isolated are unique and have never been found before in previous studies. Catalyzed reporter deposition-FISH confirmed the presence of Planctomycetes on macroalgal surfaces. This study provides the first report of the cultured diversity of Planctomycetes on the epiphytic macroalgae community and presents clear evidence of their nutritional and intimate relationship.

    2016-01-01

    Pseudopheochromocytoma has a clinical presentation that is similar to pheochromocytoma. It manifests itself with paroxysmal hypertension crises, associated with various symptoms such as headaches, chest pain, nausea, palpitations, and dizziness. Patients are usually asymptomatic in between the crises. Unlike pheochromocytoma, there is no catecholamines overproduction in this pathology: hypertensive peaks are caused by a hyperactivation of the sympathetic nervous system, which is often triggered by a psychological trauma in the past. Treatment of pseudopheochromocytoma can be challenging due to normal blood pressure values in between the hypertensive peaks; it includes alpha- and beta-blockers for moderate crises and prevention and must be combined with psychopharmacologic agents such as anxiolytics or antidepressant drugs. Psychotherapy and dietetic treatment are also crucial in pseudopheochromocytoma management.

    Cystic fibrosis (CF) is an autosomal recessive inherited metabolic disease. The mutation is located on the long arm of chromosome 7. Due to a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, chloride ion transport is reduced across the cell membrane. As a result, the disease can be described as an exocrinopathy. In all organs with exocrine glands, disorders occur in association with the defective chloride transport. The main impact of this defect is manifested in the lungs. Therefore, the most common cause of death is pulmonary disease with respiratory insufficiency due to recurrent infections. Unfortunately, a cure for the disease is still not available. However, new therapies that may affect the CFTR mutation more specifically give new hope for better therapeutic options in the future. The long-term goal of therapy is to develop a causal therapy for all six different mutation classes and thus for about 2000 mutations. PMID:25693903

    In the present paper, as we did previously in [5], we investigate the relations between the geometric properties of tilings and the algebraic and model-theoretic properties of associated relational structures. Our study is motivated by the existence of aperiodic tilings. In [5], we considered tilings of the euclidean spaces of finite dimension, and isomorphism was defined up to translation. Here, we consider, more generally, tilings of a metric space, and isomorphism is defined modulo an arbitrary group of isometries. The results of Sections 1 and 2 concern, in particular, the characterization of relational structures which can be represented by tilings of some given type, local isomorphism and the extraction preorder. In Section 3, we show that the notions of periodicity and invariance through a translation, defined for tilings of the euclidean spaces of finite dimension, can be generalized, with appropriate hypotheses, to relational structures, and in particular to tilings of non-euclidean spaces.

    Nodular, gray-white, central corneal opacities which extended from the subepithelial zone through the anterior four fifths of the stroma developed in a 50-year-old man with a longstanding history of hard contact lens wear for keratoconus. Results of histopathologic analysis of the corneal button obtained at the time of penetrating keratoplasty disclosed that the opacities were composed of amyloid. Corneal amyloidosis is rarely found in association with keratoconus. Although there were some similarities in the pattern of amyloid deposition to that seen in primary familial amyloidosis of the cornea, the authors believe that their patient is more likely to have had a secondary amyloidosis. Corneal amyloidosis should be considered in keratoconus patients with development of unusual forms of central corneal opacification. PMID:3278260

    Full Text Available World is facing rapid transition in health sector for under nutrition and over nutrition. Obesity is a challenging epidemic and increased Body Mass Index (BMI influences on almost all body systems leading to development of non-communicable diseases. Chronic but slow growing non-infectious pathology of body organization give upsurge onset of non-communicable disorders. Obesity related Non-communicable diseases (NCDs leads to millions of deaths all around the world, rapidly becoming economic burden worldwide. Pathophysiology and extend of obesity is responsible for ill effects of health. In obesity Low grade Inflammation and antioxidant disproportion plays vital role in development of NCDs. Effective health education, professional counselling from public health authorities, free health care, and social insurance can be effective in controlling growing non communicable disease globally. The present analysis attempts to study association of obesity with different NCDs in terms of prevalence and underlying mechanisms.

    Hemichannels (HCs) and gap junction channels (GJCs) formed by protein subunits called connexins (Cxs) are major pathways for intercellular communication. While HCs connect the intracellular compartment with the extracellular milieu, GJCs allow the interchange of molecules between cytoplasm of two contacting cells. Under physiological conditions, HCs are mostly closed, but they can open under certain stimuli allowing the release of autocrine and paracrine molecules. Moreover, some pathological conditions, like ischemia or other inflammation conditions, significantly increase HCs activity. In addition, some mutations in Cx genes associated with human diseases, such as deafness or cataracts, lead to the formation of more active HCs or “leaky HCs.” In this article we will revise cellular and molecular mechanisms underlying the appearance of leaky HCs, and the consequences of their expression in different cellular systems and animal models, in seeking a common pattern or pathological mechanism of disease.

    Subclinical gut inflammation has been described in up to two-thirds of patients with spondyloarthropathies (SpA). Arthritis represents an extra-intestinal manifestation of several gastrointestinal diseases,including inflammatory bowel disease (IBD), Whipple's disease, Behcet's disease, celiac disease, intestinal bypass surgery, parasitic infections of the gut and pseudomembranous colitis. Moreover about twothirds of nonsteroidal anti-inflammatory drug users demonstrate intestinal inflammation. Arthritis may manifest as a peripheral or axial arthritis. The spondyloarthropathy family consists of the following entities:ankylosing spondylitis, undifferentiated spondyloar thr i t is, react ive ar thr i t is, psor iat i c arthritis, spondyloarthritis associated with IBD,juvenile onset spondyloarthritis. This topic reviews the major gastrointestinal manifestations that can occur in patients with SpA and in nonsteroidal antiinflammatory drugs users.

    Full Text Available Background: Postoperative cognitive dysfunction (POCD has been an important complication of cardiac surgery over the years. Neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. To reduce POCD, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergoing cardiac surgery.Methods: One hundred one patients aged between 45 and 75 years undergoing elective cardiac surgery were enrolled in this study. All the surgeries were performed on-pump by the same medical team. A brief Wechsler Memory Test (WMT was administered before surgery, 3 to 5 days after the surgery, and 3 months after discharge. All related perioperative parameters were collected in order to study the effect of these parameters on the postoperative WMT scores and WMT score change.Results: The study population consisted of 101 patients, comprising 14 (13.8% females and 87 (86.2% males aged between 45 and 75 years. In univariate analysis, the baseline WMT score, serum levels of lactate dehydrogenase and T3, cross-clamp time, and preexistence of chronic obstructive pulmonary disease showed significant effects on the postoperative WMT score (p value < 0.05, whereas only the baseline WMT score and chronic obstructive pulmonary disease showed strong effects on the postoperative WMT score in the multiple regression model. In addition, the multiple regression model demonstrated a significant association between the baseline WMT score, serum creatinine level, and nitrate administration and the WMT score change.Conclusion: Our study showed that preexisting chronic obstructive pulmonary disease and preoperative high serum creatinine levels negatively affected cognitive function after surgery. In addition, there was a strong relationship between the patients’ basic cognition and POCD. Preoperative nitrate administration led to a significant improvement

    Ketamine hydrochloride, commonly used as a pediatric anesthetic agent, is an N-methyl-D-aspartic (NMDA) acid receptor antagonist with rapid onset and short duration of action. It produces a cataleptic-like state where the patient is dissociated from the surrounding environment by direct action on the cortex and limbic system. It has emerged as an increasingly popular choice among young drug users, especially within dance club venues. Cases of bladder dysfunction among recreational ketamine users were reported since Shahani et al first reported nine cases of ketamine-associated ulcerative cystitis in 2007. We report on four patients who had history of ketamine abuse, presenting with dysuria, fluctuating lower urinary tract symptoms (LUTS), lower abdominal or perineal pain, and impaired functional bladder capacities. Urinalysis showed pyuria and microhematuria. Urine culture was sterile. Bladder ulceration with severe diffuse hemorrhage and low bladder capacity were noted under anesthetized cystoscopic examination. Transurethral bladder mucosa biopsy was consistent with chronic cystitis. Cessation of ketamine abuse was the milestone of treatment, followed by the administration of mucosal protective agents, such as pentosan polysulphate or hyaluronic acid. Suprapubic pain was improved in three patients during follow-up. However, the outcome of treatment depends on the severity of the disease process, similar to that of interstitial cystitis (IC).

    2016-01-01

    Store Operated Ca(2+) Entry (SOCE), the main Ca(2+) influx mechanism in non-excitable cells, is implicated in the immune response and has been reported to be affected in several pathologies including cancer. The basic molecular constituents of SOCE are Orai, the pore forming unit, and STIM, a multidomain protein with at least two principal functions: one is to sense the Ca(2+) content inside the lumen of the endoplasmic reticulum(ER) and the second is to activate Orai channels upon depletion of the ER. The link between Ca(2+) depletion inside the ER and Ca(2+) influx from extracellular media is through a direct association of STIM and Orai, but for this to occur, both molecules have to interact and form clusters where ER and plasma membrane (PM) are intimately apposed. In recent years a great number of components have been identified as participants in SOCE regulation, including regions of plasma membrane enriched in cholesterol and sphingolipids, the so called lipid rafts, which recruit a complex platform of specialized microdomains, which cells use to regulate spatiotemporal Ca(2+) signals.

    Full Text Available Long-term lithium therapy is associated with impairment in concentrating ability and, occasionally, progression to advanced chronic kidney disease from tubulointerstitial nephropathy. Biopsy findings in patients with lithium-induced chronic tubulointerstitial nephropathy include tubular atrophy and interstitial fibrosis interspersed with tubular cysts and dilatations. Recent studies have shown that cysts are seen in 33––62.5% of the patients undergoing lithium therapy. MR imaging is highly capable of defining renal morphological features and has been demonstrated to be superior to US and CT scan for the visualization of small renal cysts. The microcysts are found in both cortex and medulla, particularly in the regions with extensive atrophy and fibrosis, and can be multiple and bilateral. They tend to be sparse and do not normally exceed 1–2 mm in diameter. The renal microcysts in the image here reported are subtle, but consistent with lithium-induced chronic nephropathy. An MRI of the kidneys provides noninvasive evidence that strengthens the diagnosis of lithium-induced nephropathy.

    2016-05-01

    Achondroplasia is the most common skeletal dysplasia. This form of dwarfism is caused by a point mutation in the fibroblast growth factor receptor 3 (FGFR3) gene, leading to inhibition of endochondral ossification for these patients. This results in a normal trunk height but shortened limbs. The discoid meniscus may be an important associated finding to better understand the common complaints of leg pain for these patients. Although the incidence for a discoid meniscus is between 3% and 5% for the general population, it is unknown with achondroplasia. This case series includes 4 patients, with ages ranging from adolescence to early adulthood, with symptoms of knee pain that were not attributable to some of the more common findings seen in this patient population. Typically, patients with achondroplasia who experience knee pain are evaluated for more common and well-known etiologies such as genu varum, ligamentous instability, and neurogenic claudication. However, the authors propose that symptomatic discoid lateral meniscus should be added to the differential diagnosis for lower-extremity pain in the achondroplasia population. A thorough history and physical examination, in combination with magnetic resonance imaging, can aid in making the diagnosis. Treatment with arthroscopic debridement, saucerization of the meniscus, and repair for unstable injuries has yielded good outcomes for this patient population. [Orthopedics. 2016; 39(3):e498-e503.].

    Isaacs' syndrome is an antibody-mediated potassium channel disorder. Clinical symptoms of Isaacs' syndrome are characterized by muscle cramp, slow relaxation following muscle contraction, and hyperhidrosis. Hyperexcitability of the peripheral nerve cause these symptoms, which are relieved by administration of Na channel blockers and immunotherapy.The target channel proteins are voltage-gated potassium channels (VGKCs). The suppression of voltage-gated outward K(+) current by antibodies induces hyperexcitability of the peripheral nerve. Electrophysiological findings show that antibodies may not directly block the kinetics of VGKCs, but may decrease channel density. From the electrophysiological, pharmacologic and immunologic view points, the site of origin of spontaneous discharges is located principally in the distal portion of the motor nerve."VGKC antibodies" are also detected in Morvan syndrome (severe insomnia with neuromyotonia and various autonomic disorders) and in a form of autoimmune limbic encephalitis. Recent studies indicated that the "VGKC antibodies" are mainly directed toward associated proteins (for example LGI-1, CASPR-2) that complex with VGKCs themselves. The "VGKC antibodies" are now usually known as VGKC-complex antibodies. In general, LGI-1 antibodies are most common in limbic encephalitis with SIADH. CASPR-2 antibodies are present in the majority of patients with Morvan syndrome.

    Antibodies against various neural surface antigens induce cognitive impairments. Anti-VGKC (voltage gated potassium channel) complex antibodies are well known as one of the causative autoantibodies. An anti-VGKC antibody was identified as the autoantibody in acquired neuromyotonia (Isaacs' syndrome), which causes muscle cramps and difficulty in opening the palm of the hands. However, this antibody also tests positive in autoimmune limbic encephalitis, which has a subacute progress and causes poor memory or epilepsy attacks. Typical cases have a distinctive adult-onset, frequent, brief dystonic seizure semiology that predominantly affects the arms and ipsilateral face. It has now been termed faciobrachial dystonic seizures. In recent years, the true target antigens of the anti-VGKC antibody of this VGKC limbic encephalitis have been recognized as leucine rich glioma inactivated protein (LGI)-1 and others. These antibodies to amnesia-related LGI-1 in limbic encephalitis neutralize the LGI-1-ADAM22 (an anchor protein) interaction and reduce synaptic AMPA receptors. There have been reports of limbic encephalitis associated with anti-VGKC complex antibodies mimicking Creutzfeldt-Jakob disease (CJD). Less than 2% of the patients with sporadic CJD (sCJD) develop serum anti-VGKC complex antibodies and, when positive, only at low titres. Low titres of these antibodies occur only rarely in suspected patients with sCJD, and when present, should be interpreted with caution.

    Ethylphenidate is a stimulant novel psychoactive substance that is an analogue of the prescription drug methylphenidate (Ritalin(®)). Methylphenidate is used commonly for the treatment of attention deficit hyperactivity disorder. Due to its stimulant effects ethylphenidate is being abused. There is a single case report of a death associated with ethylphenidate in Germany, and a case series of 19 deaths in the East of Scotland, but otherwise, the contribution of ethylphenidate to death is poorly documented. We report the analytical results of 7 cases (between February 2013 and January 2015) in which ethylphenidate was detected and quantitated with a validated liquid chromatography tandem mass spectrometry method (LC-MS/MS). The individuals (all male) ranged in age from 23 to 49 years (median 25 years). The concentration of ethylphenidate in the cases ranged from 0.026mg/L to 2.18mg/L in unpreserved post-mortem femoral blood. Only one case had ethylphenidate present as a sole drug. All other cases had at least 2 other drug classes present (benzodiazepines, heroin, methadone antipsychotics, other new psychoactive compounds). Ethylphenidate toxicity was the sole contribution to the cause of death in one case. Hanging was the cause of death in 2 cases, with the other 4 cases being reported as having occurred due to mixed drug toxicity. These data will further help with the interpretation of post-mortem ethylphenidate levels. PMID:26829338

    The associated strangeness dissociation at threshold has been studied at the COSY-11 facility measuring the hyperon - and the K+K- meson pair production. Measurements of the near threshold Lambda and Sigma0 production via the pp -> pK+ Lambda / Sigma0 reaction at COSY-11 have shown that the Lambda / Sigma0 cross section ratio exceeds the value at high excess energies (Q >= 300 MeV) by an order of magnitude. For a better understanding additional data have been taken between 13 MeV and 60 MeV excess energy. The near threshold production of the charged kaon-antikaon pair is related to the discussion about the nature of the scalar states in the 1 GeV/c^2 mass range, i.e. the f0(980) and a0(980). The interpretation as a K anti-K molecule is strongly dependent on the K anti-K interaction which can be studied via the production channel. A first total cross section value on the reaction pp -> ppK+K- at an excess energy of 17 MeV i.e. below the phi production threshold was measured.

    2012-08-01

    Pantothenate kinase-associated neurodegeneration (PKAN) is a hereditary progressive disorder and the most frequent form of neurodegeneration with brain iron accumulation (NBIA). PKAN patients present with a progressive movement disorder, dysarthria, cognitive impairment and retinitis pigmentosa. In magnetic resonance imaging, PKAN patients exhibit the pathognonomic "eye of the tiger" sign in the globus pallidus which corresponds to iron accumulation and gliosis as shown in neuropathological examinations. The discovery of the disease causing mutations in PANK2 has linked the disorder to coenzyme A (CoA) metabolism. PANK2 is the only one out of four PANK genes encoding an isoform which localizes to mitochondria. At least two other NBIA genes (PLA2G6, C19orf12) encode proteins that share with PANK2 a mitochondrial localization and all are suggested to play a role in lipid homeostasis. With no causal therapy available for PKAN until now, only symptomatic treatment is possible. A multi-centre retrospective study with bilateral pallidal deep brain stimulation in patients with NBIA revealed a significant improvement of dystonia. Recently, studies in the PANK Drosophila model "fumble" revealed improvement by the compound pantethine which is hypothesized to feed an alternate CoA biosynthesis pathway. In addition, pilot studies with the iron chelator deferiprone that crosses the blood brain barrier showed a good safety profile and some indication of efficacy. An adequately powered randomized clinical trial will start in 2012. This review summarizes clinical presentation, neuropathology and pathogenesis of PKAN. PMID:22515741

    Full Text Available Purpose: To report the occurrence of xerophthalmia and keratomalacia in a patient with Alagille syndrome. Methods: The patient's record and relevant literature were reviewed. Results: A 3-year-old boy with Alagille syndrome was examined at our institution due to severe bilateral ocular irritation. A corneal ulcer and keratomalacia were found in the right eye and severe dryness with corneal opacification was found in the left eye. He was treated with topical fortified antibiotics in the right eye, followed by amniotic membrane transplantation. Due to his systemic condition, characterized by severe cholestasis and intestinal malabsorption, a suspicion of vitamin A deficiency was raised and was later confirmed in serum analysis. Conclusion: This is the first report of xerophthalmia in a patient with Alagille syndrome. Vitamin A deficiency leading to xerophthalmia is common in developing countries; however, its occurrence in the West is rare, leading to a reduced awareness of this disorder amongst clinicians. Unusual eating habits, intestinal malabsorption and liver disease are possible causes for such a deficiency. The purpose of this case report is to raise awareness to the possibility of vitamin A deficiency in children with keratopathy, especially when associated with these disorders.

    Full Text Available Nelarabine (ara-G; Arranon; compound 506U78 is an antineoplastic purine analog used for the treatment of refractory or relapsed T-cell acute lymphoblastic leukemia (T-ALL and T-cell lymphoblastic lymphoma (T-LBL. The drug was granted accelerated approval in October 2005 by the US Food and Drug Administration (FDA given the efficacy (induction of complete responses noted in 2 single-arm trials (one in pediatric setting and one in adult patient population. The main spectra of toxicities that have been reported in these clinical trials and subsequent studies are hematological and neurological. Nelarabine induced rhabdomyolysis and increased creatinine phosphokinase (CK; CPK levels apparently have been reported and this side effect has been added as an adverse reaction in the product monograph from the drug company during postmarketing surveillance. However, the true extent and incidence of the myotoxicity from the drug are unclear. In this paper we report a grade IV CK elevation and rhabdomyolysis in a patient with T-ALL treated with nelarabine. Given the reported finding, we examined the literature further for myotoxicity, increased CK, and/or rhabdomyolysis associated with the use of the nelarabine and report our findings.

    Full Text Available Aim: Ventilator-associated pneumonia (VAP is the infection that is an important cause of morbidity and mortality developed in patients whom the invasive mechanical ventilation (MV were performed in intensive care units (ICU. In this study, the factors of VAP developing in patients whom the mechanical ventilation of ICU performed, antibiotic susceptibility to these factors and determining the risk factors were aimed. Material and Method: Between January 2009 and March 2013, 79 cases, followed with the mechanical ventilation for at least for 48 hours and developed VAP, were retrospectively reviewed at Anesthesiology and Intensive Care Unit of Reanimation at Faculty of Medicine at Yuzuncu Yil University, performing endotracheal intubation. The cases were evaluated in terms of microorganisms, antibiotic susceptibility and risk factors. Results: The rate of our VAP speed was calculated to be 19.68 on the day of 1000 ventilator. While a single microorganism could be isolated in 81.1% of the 74 VAP cases whose the active pathogen could be isolated, two or more than two microorganisms were isolated in 18.9% of them.While 83 of the strains (90.2% were gram-negative bacteria, 7 of them (7.6% were gram-positive bacteria. Acinetobacter spp. (40.2% was most commonly isolated as a gram-negative factor, but methicillin-resistant S. aureus (4.3% was isolated as a gram-positive factor. It was determined that the isolated factors in VAP cases were significantly resistant to the broad-spectrum antibiotics. Discussion: As a result, in patients with high-risk factors for the development of VAP, early and appropriate empirical antibiotic treatment should be started according to the results of the sensitivity of the unit and for the multi-drug-resistant microorganisms with common and high mortality.

    Introduction: Acquired erythroblastopenia (AE) is a rare clinical situation. It is characterized by the reduction of erythroid precursors in the bone marrow together with the low reticulocyte counts in the peripheral blood. Background: Main secondary causes of AE are drugs, Parvovirus B19 and other infectious reasons, lymphoid and myeloid neoplasia, autoimmune diseases, thymoma and pregnancy. The aim of this study is to assess the frequencies and clinical associations of AE via analyzing 12340 bone marrow samples in a retrospective manner. Material and method: Bone marrow aspirations which were obtained from patients who applied to Hacettepe University Hematology Clinic between 2002 and 2013, were analyzed retrospectively. Results: Thirty four erythroblastopenia cases were found. Patients ranged in age from 16 to 80 years with a median of 38 years. Fifteen patients were men (44%) and nineteen were women (56%). In these patients, detected causes of erythroblastopenia were MDS, idiopathic pure red cell aplasia (PRCA), parvovirus infection, post chemotherapy aplasia, plasma proliferative diseases, copper deficiency due to secondary amyloidosis, fever of unknown origin, hemophagocytic syndrome, enteric fever and legionella pneumonia. We found that between those reasons the most common causes of erythroblastopenia are MDS (17.7%) and idiopathic PRCA (17.7%). Discussion: As a result, erythroblastopenia in the bone marrow may be an early sign of MDS. In those AE cases possibility of being MDS must be kept in mind as it can be mistaken for PRCA. Conclusion: To conclude, in adults MDS without excess blast is one of the most common causes of erythroblastopenia in clinical practice and in case of erythroblastopenia the presence of MDS should be investigated.

    Full Text Available The use of angiotensin-converting enzyme (ACE inhibitors is not associated with an increased risk of acute pancreatitis [1] and, so far, only one case has been linked with the use of perindopril [2]. We report on a second patient with perindopril-induced pancreatitis. A 72-year-old man presented with a 10-day history of nausea, vomiting, and constant pain in the epigastrium which radiated to the sides. Four weeks before admission, perindopril (4 mg/day had been added to the usual regimen of glyburide (5 mg/day, metformin (1 g/day and carvedilol (6.25 mg/day which the patient had been taking for three years for the treatment of diabetes mellitus and moderate hypertension. His previous history was otherwise unremarkable, except for psoriasis; he did not report any acute or chronic pancreatic disease and denied alcohol use, toxic habits or taking any other medications including over-the-counter medications or herbal remedies. Upon admission, the patient was fully alert and oriented, apyrexial and had normal vital parameters; physical examination yielded normal findings apart from a severely tender abdomen with no bowel sounds. Laboratory data showed increased blood amylase (556 IU/L; reference range: 0-115 IU/L and lipase (1,396 IU/L; reference range: 0-190 IU/L levels; electrolytes, hematological variables, cholesterol, triglycerides, liver and renal function tests, and blood gases were normal. The results of serologic tests for the Mycoplasma and Chlamydia species, viral hepatitis, and a wide range of other viral infections were also negative. Abdominal ultrasonography and computed tomography showed a moderately enlarged and edematous pancreas; furthermore, at imaging techniques no alterations such as stones or sludge of the gallbladder and of the common bile duct were detected. A chest X-ray was also normal.

    The explanation of brain functioning in terms of the association of ideas has been popular since the 17th century. Recently, however, the process of association has been dismissed as computationally inadequate by prominent cognitive scientists. In this book, a sharper definition of the term "association" is used to revive the process by showing that associative learning can indeed be computationally powerful. Within an appropriate organization, associative learning can be embodied in a robot to realize a human-like intelligence, which sets its own goals, exhibits unique unformalizable behaviou

    2014-01-01

    Lorentz transformation is not associative. The non-associativity makes it frame dependent; and it does not fulfill relativistic requirements including reciprocity principle. The non associativity also leads to ambiguities when three or more velocities are involved. We have proposed an associative Reciprocal Symmetric Transformation (RST) to replace Lorentz transformation. RST is complex and is compatible with Pauli and Dirac algebra.

    Rushing, John A; Ranganath, Heggere; Hinke, Thomas H; Graves, Sara J

    2002-01-01

    A new type of texture feature based on association rules is described. Association rules have been used in applications such as market basket analysis to capture relationships present among items in large data sets. It is shown that association rules can be adapted to capture frequently occurring local structures in images. The frequency of occurrence of these structures can be used to characterize texture. Methods for segmentation of textured images based on association rule features are described. Simulation results using images consisting of man made and natural textures show that association rule features perform well compared to other widely used texture features. Association rule features are used to detect cumulus cloud fields in GOES satellite images and are found to achieve higher accuracy than other statistical texture features for this problem.

    The necessity to associate two geometrically distinct meshes arises in many engineering applications. Current mesh-association algorithms are generally unsuitable for the high-order geometry representations associated with high-order finite-element discretizations. In the present work we therefore propose a mesh-association method for high-order geometry representations. The associative map defines the image of a point on a mesh as its projection along a so-called smoothed normal-vector field...

  20. An Improved Technique for Ranking Semantic Associations

    Directory of Open Access Journals (Sweden)

    S Narayana

    2013-10-01

    Full Text Available The primary focus of the search techniques in the first generation of the Web is accessing relevant documents from the Web. Though it satisfies user requirements, but it is insufficient as the user sometimes wishes to access actionable information involving complex relationships between two given entities. Finding such complex relationships (also known as semantic associations is especially useful in applications such as National Security, Pharmacy, Business Intelligence etc. Therefore the next frontier is discovering relevant semantic associations between two entities present in large semantic metadata repositories. Given two entities, there exist a huge number of semantic associations between two entities. Hence ranking of these associations is required in order to find more relevant associations. For this Aleman Meza et al. proposed a method involving six metrics viz. context, subsumption, rarity, popularity, association length and trust. To compute the overall rank of the associations this method computes context, subsumption, rarity and popularity values for each component of the association and for all the associations. However it is obvious that, many components appears repeatedly in many associations therefore it is not necessary to compute context, subsumption, rarity, popularity, and trust values of the components every time for each association rather the previously computed values may be used while computing the overall rank of the associations. This paper proposes a method to reuse the previously computed values using a hash data structure thus reduce the execution time. To demonstrate the effectiveness of the proposed method, experiments were conducted on SWETO ontology. Results show that the proposed method is more efficient than the other existing methods.

    Fibromatosis refers to an extra-abdominal desmoid tumor or aggressive fibromatosis. Breast fibromatosis can develop in association with the capsule around a breast implant, although reports of cases of fibromatosis associated with breast implants are rare. As the demand for breast augmentation has increased, it is important to understand the diseases associated with breast implants. In the present report, we describe a case of breast fibromatosis that developed adjacent to a breast implant and demonstrated a relatively well-defined border even though it invaded the surrounding structures. We also explore the specific imaging features for diagnosing breast fibromatosis in association with implants by reviewing previous literature.

    Data mining, i.e. , mining knowledge from large amounts of data, is a demanding field since huge amounts of data have been collected in various applications. The collected data far exceed peoples ability to analyze it. Thus, some new and efficient methods are needed to discover knowledge from large database. Association rule discovery is an important problem in knowledge discovery and data mining.The association mining task consists of identifying the frequent item sets and then forming conditional implication rule among them. In this paper, we describe and summarize recent work on association rule discovery, offer a new method to association rule mining and point out that association rule discovery can be applied in spatial data mining. It is useful to discover knowledge from remote sensing and geographical information system.``

  10. Holographic associative memories in document retrieval systems

    International Nuclear Information System (INIS)

    The objective of this work was the implementation of a holographic memory with associative readout for a document retrieval system. Taking advantage of the favourable properties of holography - associative readout of the memory, parallel processing in the response store - may give shorter response times than sequentially organized data memories. Such a system may also operate in the interactive mode including chain associations. In order to avoid technological difficulties, the experimental setup made use of commercially available components only. As a result an improved holographic structure is proposed which uses volume holograms in photorefractive crystals as storage device. In two chapters of appendix we give a review of the state of the art of electrooptic devices for coherent optical data processing and of competing technologies (semiconductor associative memories and associative program systems).

    Learning to associate specific objects or actions with rewards and remembering the associations are everyday tasks crucial for our flexible adaptation to the environment. These higher-order cognitive processes depend on the prefrontal cortex (PFC) and frontostriatal circuits that connect areas in the frontal lobe with the striatum in the basal ganglia. Both structures are densely innervated by dopamine (DA) afferents that originate in the midbrain. Although the activity of DA neurons is thought to be important for learning, the exact role of DA transmission in frontostriatal circuits during learning-related tasks is still unresolved. Moreover, the neural substrates of this modulation are poorly understood. Here, we review our recent work in monkeys utilizing local pharmacology of DA agents in the PFC to investigate the cellular mechanisms of DA modulation of associative learning and memory. We show that blocking both D1 and D2 receptors in the lateral PFC impairs learning of new stimulus-response associations and cognitive flexibility, but not the memory of highly familiar associations. In addition, D2 receptors may also contribute to motivation. The learning deficits correlated with reductions of neural information about the associations in PFC neurons, alterations in global excitability and spike synchronization, and exaggerated alpha and beta neural oscillations. Our findings provide new insights into how DA transmission modulates associative learning and memory processes in frontostriatal systems. PMID:25241063

    To identify MRI features associated with appendicitis. Features expected to be associated with appendicitis were recorded in consensus by two expert radiologists on 223 abdominal MRIs in patients with suspected appendicitis. Nine MRI features were studied: appendix diameter >7 mm, appendicolith, peri-appendiceal fat infiltration, peri-appendiceal fluid, absence of gas in the appendix, appendiceal wall destruction, restricted diffusion of the appendiceal wall, lumen or focal fluid collections. Appendicitis was assigned as the final diagnosis in 117/223 patients. Associations between imaging features and appendicitis were evaluated with logistic regression analysis. All investigated features were significantly associated with appendicitis in univariate analysis. Combinations of two and three features were associated with a probability of appendicitis of 88 % and 92 %, respectively. In patients without any of the nine features, appendicitis was present in 2 % of cases. After multivariate analysis, only an appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall were significantly associated with appendicitis. The probability of appendicitis was 96 % in their presence and 2 % in their absence. An appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall have the strongest association with appendicitis on MRI. (orig.)

    2009-01-01

    Hydrophobically associative polyacrylamide (HAPAM) were prepared in aqueous solution by radical copolymerization of novel cationic surface-active monomer, dimethylhexadecyl(3-acrylamidopropyl)ammonium bromide (DMHAB), with acrylarnide (AM) in the presence of DMHAB/CTAB mixed micelles. The length of hydrophobic microblock (N_H) in HAPAM is controlled by the molar fraction of DMHAB in mixed micelles, which can be mediated by the ratio of CTAB to DMHAB. The results of steady-state fluorescence probe and viscometry experiments showed the ability of HAPAM association was determined by the length of the hydrophobic microblock. HAPAM with tunable association ability are promising materials for thickening agent.

    Full Text Available The association of multisystem pathologic conditions and epidermal nevi, known as the epidermal nevus syndrome, includes disorders of bone, central nervous system, eye, kidney, vasculature and skin. Rarely, congenital nevomelanocytic nevus also known as hairy nevus has also been reported in association with hypophosphatemic rickets. Studies suggest that phosphaturia, caused by circulating factors, called "phosphatonins" may be secreted by an epidermal or hairy nevus. We report here, a rare case of hypophosphatemic rickets associated with a giant hairy nevus in a 10-year-old boy.

    2015-10-01

    Contrast-associated acute kidney injury (CAAKI) is a common iatrogenic condition. The principal risk factors for CAAKI are underlying renal impairment; diabetes in the setting of kidney disease; and intravascular volume depletion, effective or absolute. CAAKI is associated with serious adverse short-term and long-term outcomes, including mortality and more rapidly progressive chronic kidney disease, although the causal nature of these associations remains unproved. Patients with chronic kidney disease and other risk factors for CAAKI who present with acute coronary syndrome should undergo indicated angiographic procedures.

    2014-03-01

    A data mining study that examined associations between 105 drugs and 55 cancer sites found significant associations between 2 selective serotonin reuptake inhibitors (fluoxetine and paroxetine) and testicular cancer. The study suggested several reasons why these associations merited further investigation. A later study tested specific relationships between 12 antidepressant drugs and testicular cancer and subtypes thereof; whereas significant relationships were again found, these disappeared after adjusting for confounding variables. These 2 studies are educative because they illustrate how false-positive results can easily arise in exploratory research and how confounding may be responsible for statistically significant relationships in study designs that are not randomized controlled trials.

    2012-02-03

    Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

    2004-01-01

    There is mounting evidence that long duration gamma ray bursts (GRBs) and X-ray flashes (XRFs) are produced by highly relativistic and narrowly collimated jets ejected in core collapse supernova (SN) explosions akin to SN 1998bw. We review the history of the GRB-SN association idea and its observational verification. We summarize the present evidence for a GRB/XRF-SN association. We comment on the possibility that most, perhaps all, SN explosions produce GRBs, including SNe of Type Ia which may produce short GRBs/XRFs. We list the major open questions that follow from a GRB/XRF-SN association. Possible uses of the GRB-SN association in cosmology are pointed out.

  20. Controlling False Positives in Association Rule Mining

    CERN Document Server

    Liu, Guimei; Wong, Limsoon

    2011-01-01

    Association rule mining is an important problem in the data mining area. It enumerates and tests a large number of rules on a dataset and outputs rules that satisfy user-specified constraints. Due to the large number of rules being tested, rules that do not represent real systematic effect in the data can satisfy the given constraints purely by random chance. Hence association rule mining often suffers from a high risk of false positive errors. There is a lack of comprehensive study on controlling false positives in association rule mining. In this paper, we adopt three multiple testing correction approaches---the direct adjustment approach, the permutation-based approach and the holdout approach---to control false positives in association rule mining, and conduct extensive experiments to study their performance. Our results show that (1) Numerous spurious rules are generated if no correction is made. (2) The three approaches can control false positives effectively. Among the three approaches, the permutation...

    Segmental neurofibromatosis (SN) is a rare disorder characterized by neurofibromas or neurofibromas with café-au-lait spots limited to one region of the body without crossing the midline. Renal angiomyolipomas (AMLs) are rare benign neoplasms usually found in association with tuberous sclerosis (TS). Similar to neurofibromatosis (NF), TS has a high spontaneous mutation rate and a family history often is absent. Although both are autosomal dominant diseases with neural involvement, there are few reports in the literature demonstrating a link between the 2 disorders. We report a case of SN associated with renal AMLs. To our knowledge, there has been only 1 prior report of renal AML associated with NF type 1 (NF1), and there have been no prior reports of SN associated with AML. PMID:18712027

    Full Text Available Abstract Background Kocuria, previously classified into the genus of Micrococcus, is commonly found on human skin. Two species, K. rosea and K. kristinae, are etiologically associated with catheter-related bacteremia. Case presentation We describe the first case of K. kristinae infection associated with acute cholecystitis. The microorganism was isolated from the bile of a 56-year old Chinese man who underwent laparoscopic cholecystectomy. He developed post-operative fever that resolved readily after levofloxacin treatment. Conclusion Our report of K. kristinae infection associated with acute cholecystitis expands the clinical spectrum of infections caused by this group of bacteria. With increasing number of recent reports describing the association between Kocuria spp. and infectious diseases, the significance of their isolation from clinical specimens cannot be underestimated. A complete picture of infections related to Kocuria spp. will have to await the documentation of more clinical cases.

  20. Is hidradenitis suppurativa associated with anaemia?

    DEFF Research Database (Denmark)

    Miller, I M; Johansen, M E; Mogensen, U B;

    2016-01-01

    BACKGROUND: Chronic inflammatory diseases may be associated with anaemia of inflammation. Hidradenitis suppurativa is a chronic inflammatory dermatological disease associated with metabolic comorbidities, low quality of life and fatigue. Anaemia may cause fatigue, and it has been hypothesized...... that HS-related fatigue may be partly due to anaemia. OBJECTIVE: Our objective was to investigate a possible association between HS and anaemia. METHODS: We performed a hospital-based and population-based cross-sectional study investigating the red blood cell profile, i.e. haemoglobin. RESULTS: We...... revealed that 60% had normocytic anaemia and 40% microcytic anaemia, in concordance with anaemia of inflammation. CONCLUSION: In contrast to our hypothesis, this study showed that HS is not associated with anaemia. Thus, anaemia may not be the cause of the described fatigue in HS patients. Furthermore...

    Full Text Available Abstract Background The study of relationships between human diseases provides new possibilities for biomedical research. Recent achievements on human genetic diseases have stimulated interest to derive methods to identify disease associations in order to gain further insight into the network of human diseases and to predict disease genes. Results Using about 10000 manually collected causal disease/gene associations, we developed a statistical approach to infer meaningful associations between human morbidities. The derived method clustered cardiometabolic and endocrine disorders, immune system-related diseases, solid tissue neoplasms and neurodegenerative pathologies into prominent disease groups. Analysis of biological functions confirmed characteristic features of corresponding disease clusters. Inference of disease associations was further employed as a starting point for prediction of disease genes. Efforts were made to underpin the validity of results by relevant literature evidence. Interestingly, many inferred disease relationships correspond to known clinical associations and comorbidities, and several predicted disease genes were subjects of therapeutic target research. Conclusions Causal molecular mechanisms present a unifying principle to derive methods for disease classification, analysis of clinical disorder associations, and prediction of disease genes. According to the definition of causal disease genes applied in this study, these results are not restricted to genetic disease/gene relationships. This may be particularly useful for the study of long-term or chronic illnesses, where pathological derangement due to environmental or as part of sequel conditions is of importance and may not be fully explained by genetic background.

Some activities appear only in one of four blocks, others appear in more than one block, as there is an overlap of activities supported by relationship marketing.

  7. Function of cancer associated genes revealed by modern univariate and multivariate association tests.

    Directory of Open Access Journals (Sweden)

    Malka Gorfine

    Full Text Available Copy number variation (CNV plays a role in pathogenesis of many human diseases, especially cancer. Several whole genome CNV association studies have been performed for the purpose of identifying cancer associated CNVs. Here we undertook a novel approach to whole genome CNV analysis, with the goal being identification of associations between CNV of different genes (CNV-CNV across 60 human cancer cell lines. We hypothesize that these associations point to the roles of the associated genes in cancer, and can be indicators of their position in gene networks of cancer-driving processes. Recent studies show that gene associations are often non-linear and non-monotone. In order to obtain a more complete picture of all CNV associations, we performed omnibus univariate analysis by utilizing dCov, MIC, and HHG association tests, which are capable of detecting any type of association, including non-monotone relationships. For comparison we used Spearman and Pearson association tests, which detect only linear or monotone relationships. Application of dCov, MIC and HHG tests resulted in identification of twice as many associations compared to those found by Spearman and Pearson alone. Interestingly, most of the new associations were detected by the HHG test. Next, we utilized dCov's and HHG's ability to perform multivariate analysis. We tested for association between genes of unknown function and known cancer-related pathways. Our results indicate that multivariate analysis is much more effective than univariate analysis for the purpose of ascribing biological roles to genes of unknown function. We conclude that a combination of multivariate and univariate omnibus association tests can reveal significant information about gene networks of disease-driving processes. These methods can be applied to any large gene or pathway dataset, allowing more comprehensive analysis of biological processes.

  8. Inferring Protein Associations Using Protein Pulldown Assays

    Sharp, Julia L.; Anderson, Kevin K.; Daly, Don S.; Auberry, Deanna L.; Borkowski, John J.; Cannon, William R.

    2007-02-01

    Background: One method to infer protein-protein associations is through a “bait-prey pulldown” assay using a protein affinity agent and an LC-MS (liquid chromatography-mass spectrometry)-based protein identification method. False positive and negative protein identifications are not uncommon, however, leading to incorrect inferences. Methods: A pulldown experiment generates a protein association matrix wherein each column represents a sample from one bait protein, each row represents one prey protein and each cell contains a presence/absence association indicator. Our method evaluates the presence/absence pattern across a prey protein (row) with a Likelihood Ratio Test (LRT), computing its p-value with simulated LRT test statistic distributions after a check with simulated binomial random variates disqualified the large sample 2 test. A pulldown experiment often involves hundreds of tests so we apply the false discovery rate method to control the false positive rate. Based on the p-value, each prey protein is assigned a category (specific association, non-specific association, or not associated) and appraised with respect to the pulldown experiment’s goal and design. The method is illustrated using a pulldown experiment investigating the protein complexes of Shewanella oneidensis MR-1. Results: The Monte Carlo simulated LRT p-values objectively reveal specific and ubiquitous prey, as well as potential systematic errors. The example analysis shows the results to be biologically sensible and more realistic than the ad hoc screening methods previously utilized. Conclusions: The method presented appears to be informative for screening for protein-protein associations.

  9. Multivariate Analysis of Genotype-Phenotype Association.

    2016-04-01

    With the advent of modern imaging and measurement technology, complex phenotypes are increasingly represented by large numbers of measurements, which may not bear biological meaning one by one. For such multivariate phenotypes, studying the pairwise associations between all measurements and all alleles is highly inefficient and prevents insight into the genetic pattern underlying the observed phenotypes. We present a new method for identifying patterns of allelic variation (genetic latent variables) that are maximally associated-in terms of effect size-with patterns of phenotypic variation (phenotypic latent variables). This multivariate genotype-phenotype mapping (MGP) separates phenotypic features under strong genetic control from less genetically determined features and thus permits an analysis of the multivariate structure of genotype-phenotype association, including its dimensionality and the clustering of genetic and phenotypic variables within this association. Different variants of MGP maximize different measures of genotype-phenotype association: genetic effect, genetic variance, or heritability. In an application to a mouse sample, scored for 353 SNPs and 11 phenotypic traits, the first dimension of genetic and phenotypic latent variables accounted for >70% of genetic variation present in all 11 measurements; 43% of variation in this phenotypic pattern was explained by the corresponding genetic latent variable. The first three dimensions together sufficed to account for almost 90% of genetic variation in the measurements and for all the interpretable genotype-phenotype association. Each dimension can be tested as a whole against the hypothesis of no association, thereby reducing the number of statistical tests from 7766 to 3-the maximal number of meaningful independent tests. Important alleles can be selected based on their effect size (additive or nonadditive effect on the phenotypic latent variable). This low dimensionality of the genotype-phenotype map

    The objective of this study was to establish the risk factors associated with both lambing difficulty and lamb mortality in the Irish sheep multibreed population. A total of 135 470 lambing events from 42 675 ewes in 839 Irish crossbred and purebred flocks were available. Risk factors associated with producer-scored ewe lambing difficulty score (scale of one (no difficulty) to four (severe difficulty)) were determined using linear mixed models. Risk factors associated with the logit of the probability of lamb mortality at birth (i.e. binary trait) were determined using generalised estimating equations. For each dependent variable, a series of simple regression models were developed as well as a multiple regression model. In the simple regression models, greater lambing difficulty was associated with quadruplet bearing, younger ewes, of terminal breed origin, lambing in February; for example, first parity ewes experienced greater (P7.0 kg) birth weights, quadruplet born lambs and lambs that experienced a more difficult lambing (predicted probability of death for lambs that required severe and veterinary assistance of 0.15 and 0.32, respectively); lambs from dual-purpose breeds and born to younger ewes were also at greater risk of mortality. In the multiple regression model, the association between ewe parity, age at first lambing, year of lambing and lamb mortality no longer persisted. The trend in solutions of the levels of each fixed effect that remained associated with lamb mortality in the multiple regression model, did not differ from the trends observed in the simple regression models although the differential in relative risk between the different lambing difficulty scores was greater in the multiple regression model. Results from this study show that many common flock- and animal-level factors are associated with both lambing difficulty and lamb mortality and management of different risk category groups (e.g. scanned litter sizes, ewe age groups) can be used

    Full Text Available AbstractBackground: Endometriosis is a common gynecological problem associated with chronic pelvic pain. Objective: To evaluate the effectiveness of current hormonal treatments of endometriosis associated pain.Materials and Methods: Randomized Controlled studies identified from databases of Medline and Cochrane Systemic Review groups were pooled. 7 RCTs were recruited for evaluation in this review. Data from these studies were pooled and meta-analysis was performed in three comparison groups: 1 Progestogen versus GnRHa; 2 Implanon versus Progestogen (injection; 3 Combined oral contraceptive pills versus placebo and progestogen. Response to treatment was measured as a reduction in pain score. Pain improvement was defined as improvement ≥1 at the end of treatment. Results: There was no significant difference between treatment groups of progestogen and GnRHa (RR: 0.036; CI:-0.030-0.102 for relieving endometriosis associated pelvic pain. Long acting progestogen (Implanon and Mirena are not inferior to GnRHa and depot medroxy progesterone acetate (DMPA (RR: 0.006; CI:-0.142-0.162. Combined oral contraceptive pills demonstrated effective treatment of relieving endometriosis associated pelvic pain when compared with placebo groups (RR:0.321CI-0.066-0.707. Progestogen was more effective than combined oral contraceptive pills in controlling dysmenorrhea (RR:-0.160; CI:-0.386-0.066, however, progestogen is associated with more side effects like spotting and bloating than the combined contraceptive pills. Conclusion: Combined oral contraceptive pills (COCP, GnRHa and progestogens are equally effective in relieving endometriosis associated pelvic pain. COCP and progestogens are relatively cheap and more suitable for long-term use as compared to GnRHa. Long-term RCT of medicated contraceptive devices like Mirena and Implanon are required to evaluate their long-term effects on relieving the endometriosis associated pelvic pain

    Life span is a complex and multifactorial trait, which is shaped by genetic, epigenetic, environmental, and stochastic factors. The possibility that highly hypervariable short tandem repeats (STRs) associated with longevity has been largely explored by comparing the genotypic pools of long lived and younger individuals, but results so far have been contradictory. In view of these contradictory findings, the present study aims to investigate whether HUMTHO1 and HUMCSF1PO STRs, previously associated with longevity, exert a role as a modulator of life expectancy, as well as to assess the extent to which other autosomal STR markers are associated with human longevity in population from northern Spain. To that end, 21 autosomal microsatellite markers have been studied in 304 nonagenarian individuals (more than 90 years old) and 516 younger controls of European descent. Our results do not confirm the association found in previous studies between longevity and THO1 and CSF1PO loci. However, significant association between longevity and autosomal STR markers D12S391, D22S1045, and DS441 was observed. Even more, when we compared allelic frequency distribution of the 21 STR markers between cases and controls, we found that 6 out of the 21 STRs studied showed different allelic frequencies, thus suggesting that the genomic portrait of the human longevity is far complex and probably shaped by a high number of genomic loci.

    2014-05-01

    Full Text Available The presence and association of fungi with sessile marine animals such as coral and sponges has been well established, yet information on the extent of diversity of the associated fungi is still in its infancy. Culture- as well as metagenomic- and transcriptomic-based analyses have shown that fungal presence in association with these animals can be dynamic and can include core residents as well as shifts in fungal communities. Evidence for detrimental and beneficial interactions between fungi and their marine hosts is accumulating and current challenges include the elucidation of the chemical and cellular crosstalk between fungi and their associates within the holobionts. The ecological function of fungi in association with sessile marine animals is complex and is founded on a combination of factors such as fungal origin, host health, environmental conditions and the presence of other resident or invasive microorganisms in the host. Based on evidence from the much more studied terrestrial systems, the evaluation of marine animal-fungal symbioses under varying environmental conditions may well prove to be critical in predicting ecosystem response to global change, including effects on the health of sessile marine animals.

  14. Cross-cultural color-odor associations.

    Directory of Open Access Journals (Sweden)

    Carmel A Levitan

    Full Text Available Colors and odors are associated; for instance, people typically match the smell of strawberries to the color pink or red. These associations are forms of crossmodal correspondences. Recently, there has been discussion about the extent to which these correspondences arise for structural reasons (i.e., an inherent mapping between color and odor, statistical reasons (i.e., covariance in experience, and/or semantically-mediated reasons (i.e., stemming from language. The present study probed this question by testing color-odor correspondences in 6 different cultural groups (Dutch, Netherlands-residing-Chinese, German, Malay, Malaysian-Chinese, and US residents, using the same set of 14 odors and asking participants to make congruent and incongruent color choices for each odor. We found consistent patterns in color choices for each odor within each culture, showing that participants were making non-random color-odor matches. We used representational dissimilarity analysis to probe for variations in the patterns of color-odor associations across cultures; we found that US and German participants had the most similar patterns of associations, followed by German and Malay participants. The largest group differences were between Malay and Netherlands-resident Chinese participants and between Dutch and Malaysian-Chinese participants. We conclude that culture plays a role in color-odor crossmodal associations, which likely arise, at least in part, through experience.

    Full Text Available The literature documents that personality characteristics are associated with healthy lifestyles, including smoking. Among positive traits, Positivity (POS, defined as a general disposition conducive to facing experience under a positive outlook has shown robust associations with psychological health. Thus, the present study investigated the extent to which POS is able to predict (i relapse after quitting smoking and (ii the desire to smoke again. All participants (481 had previously attended a Group Counselling Program (GCP for Smoking Cessation (from 2005 through 2010. They were contacted through telephone interview. Among participants, 244 were ex-smokers (age: years 56.3±10.08, 52% female and 237 were still-smokers (age: years 55.0±9.63; 63.5% female. The association of POS with “craving to smoke” levels was assessed with multivariate linear regression analysis while controlling also for important differences in personality such as conscientiousness and general self-efficacy, as well as for gender and age. Results showed that POS was significantly and negatively associated with smoking status and with craving to smoke. Among covariates (i.e., conscientiousness, generalized self-efficacy, gender was associated with smoking status and with craving to smoke. Altogether these findings corroborate the idea that POS plays a significant role in sustaining individuals' efforts to quit smoking.

    Diabetic maculopathy is characterised by increased capillary leakage in the main retinal vessels and by alterations in the microcirculation of the macula. Maculopathy occurs frequently in type 1 and type 2 diabetic patients. Prevalence is higher in type 2 than in type 1 diabetic patients. Factors associated with the development of maculopathy are mostly unknown. As maculopathy is the main cause of vision deprivation in diabetic patients it is essential to know the associations and risk factors of diabetic maculopathy so that appropriate measures can be taken to prevent as well as treat diabetic maculopathy. We started the research work to find out the relation between diabetic maculopathy and various associated factors and risk factors for patients with diabetic retinopathy with maculopathy. This cross-sectional observational study done at the Department of Ophthalmology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka & National Institute of Ophthalmology & Hospital (NIO & H), Sher-e-Bangla Nagar, Dhaka, Bangladesh from January 2006 to June 2006. In this study out of 50 patients, diabetes was controlled in 20(40%) patients and uncontrolled in 30(60%). A significant percentage of patients (40%) had elevated blood pressure. Diabetic autonomic neuropathy was observed in 24% cases and polyneuropathy was observed in 36% cases. It is evident that diabetic maculopathy has association with dyslipidaemia, abnormal renal function due to nephropathy. This study lighted on the association of diabetic maculopathy with diabetic nephropathy, cardiac abnormalities and diabetic neuropathy. PMID:27277354

    2012-12-01

    Equine periodontal disease (EPD) is a common and painful condition, the aetiology and pathology of which are poorly understood. To characterise the histopathological lesions associated with EPD, the skulls of 22 horses were assessed grossly for the presence of periodontal disease, and a standard set of interdental tissues taken from each for histopathological examination. Histological features of EPD included ulceration and neutrophilic inflammation of the gingival epithelium. Mononuclear and eosinophilic inflammation of the gingival lamina propria and submucosa was commonly present irrespective of the presence or degree of periodontal disease. Gingival hyperplasia was present to some degree in all horses, and was only weakly associated with the degree of periodontal disease. In all horses dental plaque was present at the majority of sites examined and was often associated with histological evidence of peripheral cemental erosion. Bacteria (including spirochaetes in four horses) were identified in gingival samples by Gram and silver impregnation techniques and were significantly associated with the presence of periodontal disease. This is the first study to describe histological features of EPD, and the first to identify associated spirochaetes in some cases. Histological features were variable, and there was considerable overlap of some features between the normal and diseased gingiva. Further investigation into the potential role of bacteria in the pathogenesis and progression of EPD is warranted.

    Objectives This paper proposes a novel semantic method for auditing associative relations in biomedical terminologies. We tested our methodology on two Unified Medical Language System (UMLS) knowledge sources. Methods We use the UMLS semantic groups as high-level representations of the domain and range of relationships in the Metathesaurus and in the Semantic Network. A mapping created between Metathesaurus relationships and Semantic Network relationships forms the basis for comparing the signatures of a given Metathesaurus relationship to the signatures of the semantic relationship to which it is mapped. The consistency of Metathesaurus relations is studied for each relationship. Results Of the 177 associative relationships in the Metathesaurus, 84 (48%) exhibit a high degree of consistency with the corresponding Semantic Network relationships. Overall, 63% of the 1.8M associative relations in the Metathesaurus are consistent with relations in the Semantic Network. Conclusion The semantics of associative relationships in biomedical terminologies should be defined explicitly by their developers. The Semantic Network would benefit from being extended with new relationships and with new relations for some existing relationships. The UMLS editing environment could take advantage of the correspondence established between relationships in the Metathesaurus and the Semantic Network. Finally, the auditing method also yielded useful information for refining the mapping of associative relationships between the two sources. PMID:19475724

    The nature of episodic associations has been subject to a long standing debate, where the two opposing positions postulate associations as either a holistic representation of the constituent elements or as independently modifiable pointers between them. In spite of a history of inconsistent findings, evidence in favour of the theory of symmetric associations has accumulated, yet only for verbal memory [Caplan, J. B., Glaholt, M. G., & McIntosh, A. R. (2006). Linking associative and serial list memory: Pairs versus triples. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(6), 1244-1265; Kahana, M. J. (2002). Associative symmetry and memory theory. Memory and Cognition, 30(6), 823-840]. Although object-location associations differ in several fundamental characteristics from verbal paired-associates, we recently found associative symmetry in the memory for this class of associations as well [Sommer, T., Rose, M., & Büchel, C. (2007). Associative symmetry vs. independent associations in the memory for object-location associations. Journal of Experimental Psychology: Learning, Memory, and Cognition, 33(1), 90-106]. Due to the inconsistencies in the verbal literature, we felt it to be pertinent to confirm this finding using another experimental approach. Based on recent advances in understanding the effects of successive testing, we were able to make use of this knowledge and introduce this effect as an experimental manipulation in the study of associative symmetry. In particular, we investigated whether the influence of a prior memory test on a subsequent memory test differs when the same or opposite constituent element of an object-location paired-associate cues the retrieval on each test. We observed an identical testing effect for both conditions, which was exclusively driven by reminiscence, the recovery of previously inaccessible information. This finding lends strong support in favour of holistically or symmetrically represented object

    2011-12-01

    Full Text Available Previous research identified two main emotional outcomes of computer error: anxiety and frustration. These emotions have been associated with low levels of performance in using a computer. The present research used innovative methodology for studying the relations between computer error messages, user anxiety and user frustration. We used the Implicit Association Test (IAT to measure automated associations between error messages and these two emotional outcomes. A sample of 80 participants completed two questionnaires and two IAT designs. Results indicated that user error messages are more strongly associated with anxiety, than with frustration. Personal characteristics such as emotional stability and English proficiency were significantly associated with the implicit anxiety measure, but not with the frustration measure. No significant relations were found between two measures of computer experience and the emotional measures. These results indicated that error related anxiety is associated with personal characteristics.

    2015-01-01

    Full Text Available Using cross-sectional data collected from three middle schools in Southeast Los Angeles, we assessed the association of neighborhood violence exposure, gang associations, and social self-control with past week aggression in a sample of minority youth (n=164. Results from Poisson and logistic regression models showed that direct exposure to gun violence, having friends in gangs, and low social self control were all positively associated with past week aggression. Among girls, having gang affiliated family members was positively associated with aggression, whereas among boys having friends in gangs was associated with past week aggression. Subjective expectations of engagement in future interpersonal violence were associated with being male, having friends in gangs, and fear of neighborhood gun violence. We recommend that youth violence prevention and intervention programs address the impact of family, peers, and gun violence on student coping and identify students with low social self-control who could benefit from social and emotional skills training.

  2. Automatic Metadata Generation using Associative Networks

    2008-01-01

    In spite of its tremendous value, metadata is generally sparse and incomplete, thereby hampering the effectiveness of digital information services. Many of the existing mechanisms for the automated creation of metadata rely primarily on content analysis which can be costly and inefficient. The automatic metadata generation system proposed in this article leverages resource relationships generated from existing metadata as a medium for propagation from metadata-rich to metadata-poor resources. Because of its independence from content analysis, it can be applied to a wide variety of resource media types and is shown to be computationally inexpensive. The proposed method operates through two distinct phases. Occurrence and co-occurrence algorithms first generate an associative network of repository resources leveraging existing repository metadata. Second, using the associative network as a substrate, metadata associated with metadata-rich resources is propagated to metadata-poor resources by means of a discrete...

    Smallpox was eradicated 34 years ago due to the success of the smallpox vaccine; yet, the vaccine continues to be studied because of its importance in responding to potential biological warfare and the adverse events associated with current smallpox vaccines. Interindividual variations in vaccine response are observed and are, in part, due to genetic variation. In some cases, these varying responses lead to adverse events, which occur at a relatively high rate for the smallpox vaccine compared with other vaccines. Here, we aim to summarize the cytokine responses associated with smallpox vaccine response to date. Along with a description of each of these cytokines, we describe the genetic and adverse event data associated with cytokine responses to smallpox vaccination.

    l-asparaginase has been an element in the treatment for acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma since the late 1960s and remains an essential component of their combination chemotherapy. Among the major toxicities associated with l-asparaginase therapy are pancreatitis......, allergic reactions, thrombotic events, hepatotoxicity and hyperlipidaemia. Acute pancreatitis is one of the most common reasons for stopping treatment with l-asparaginase. Short-term complications of asparaginase-associated pancreatitis include development of pseudocysts and pancreatic necrosis. Long......-term complications include chronic pancreatitis and diabetes. The pathophysiology of asparaginase-associated pancreatitis remains to be uncovered. Individual clinical and genetic risk factors have been identified, but they are only weak predictors of pancreatitis. This review explores the definition, possible risk...

    Clostridium difficile has recently become recognized as an important nosocomial pathogen. This review summarizes what is known about the isolation of the organism, the spectrum of clinical disease, virulence factors, treatments, and methods of prevention. Risk factors for C. difficile disease are also discussed. The most important risk factor is the use of certain antibiotics (ampicillin, cephalosporins, and clindamycin). C. difficile is associated with 96% to 100% of cases of pseudomembraneous colitis, 60% to 75% of antibiotic-associated cases of colitis, and 11% to 33% of antibiotic-associated cases of diarrhea. Other risk factors include gastrointestinal manipulations, advanced age, female sex, inflammatory bowel disease, cancer chemotherapy, and renal disorders. Hospital outbreaks of C. difficile disease are examined. Data from nosocomial outbreaks support transmission of C. difficile by contaminated fomites and hand carriage by hospital personnel.

    Several lifestyle factors have been found to be associated with vitamin D status in cross-sectional studies, but it is not clear whether a change in these factors can actually affect the vitamin D level. We investigated the association between repeated measurements of physical activity, body mass...... index (BMI), diet, alcohol consumption, and smoking habits, and corresponding levels of vitamin D during 5 years of follow-up of a large general population sample. We included 4185 persons who participated and had vitamin D (serum-25-hydroxyvitamin D, 25-OH-D) measurements in the Inter99 study...... at baseline (1999-2001) and 5-year follow-up. In a subsample, 25-OH-D was also measured at 1- and 3-year follow-ups. We used mixed models to examine the association between repeated measurements of lifestyle factors and 25-OH-D levels. In multivariable analyses of repeated measurements, the difference in 25...

    Tertiary amines dissolved in diluents are attractive extractants for recovery of carboxylic acids from dilute aqueous solutions. Quantitative Fourier transform infrared (FTIR) analysis of organic solutions containing various concentrations of trioctylamine (TOA), n-octanol, and propionic acid was carried out, and liquid-liquid equilibrium was investigated using TOA in n-octanol as the solvent. The fraction of ion-pair association between TOA and propionic acid in the organic phase was quantitatively determined by FTIR. The apparent reactive extraction equilibrium constant, K11, was calculated using the quantitative FTIR spectrum and the equilibrium data. The results show that the fraction of ion-pair association depends on diluent concentration, complex dissolution for propionic acid, and association between TOA and propionic acid. The K11 based on quantitative FTIR has the same loading trend as that from the equilibrium data.

    Vasculitis in connective tissue disease (CTD) is quite rare, it is reported in approximately 10% of patients with CTD; systemic lupus erythematosus (SLE) shows the highest association rate. Vessels of any size may be involved, but mainly small vessels vasculitis is reported. At present the classification of these vasculitis is unsatisfactory. According to the 2012 revised International Chapel Hill Consensus Conference, vasculitides secondary to CTD are a well identified entity and are classified under the category of "vasculitis associated with systemic disease". However only lupus vasculitis and rheumatoid vasculitis are explicitly listed, while the remaining are generically included under the heading "others". Petechiae, purpura, gangrene and ulcers are the most frequent cutaneous manifestations that should investigated in order to rule out potentially dangerous systemic involvement, especially if cryoglobulinemic or necrotizing vasculitis are suspected. This review will focus on the cutaneous involvement in CTD associated vasculitis. PMID:25732106

  9. Neurobiology of inflammation-associated anorexia

    Directory of Open Access Journals (Sweden)

    Laurent Gautron

    2010-01-01

    Full Text Available Compelling data demonstrate that inflammation-associated anorexia directly results from the action of pro-inflammatory factors, primarily cytokines and prostaglandins E2, on the nervous system. For instance, the aforementioned pro-inflammatory factors can stimulate the activity of peripheral sensory neurons, and induce their own de novo synthesis and release into the brain parenchyma and cerebrospinal fluid. Ultimately, it results in the mobilization of a specific neural circuit that shuts down appetite. The present article describes the different cell groups and neurotransmitters involved in inflammation-associated anorexia and examines how they interact with neural systems regulating feeding such as the melanocortin system. A better understanding of the neurobiological mechanisms underlying inflammation-associated anorexia will help to develop appetite stimulants for cancer and AIDS patients.

    The principle of information retrieval by association has been suggested as a basis for parallel computing and as the process by which human memory functions.1 Various associative processors have been proposed that use electronic or optical means. Optical schemes,2-7 in particular, those based on holographic principles,8'8' are well suited to associative processing because of their high parallelism and information throughput. Previous workers8 demonstrated that holographically stored images can be recalled by using relatively complicated reference images but did not utilize nonlinear feedback to reduce the large cross talk that results when multiple objects are stored and a partial or distorted input is used for retrieval. These earlier approaches were limited in their ability to reconstruct the output object faithfully from a partial input.

However, sever enlargement associated with an aggressive type of periodontitis is an infrequent finding. Reported here is a case of a female patient aged 18 years who presented with severe enlargement of the maxillary and mandibular gingiva. Examination revealed enlargement extending up to the incisal edge of all the teeth and also an associated generalized loss of attachment with radiographic evidence of reduced bone height resembling an aggressive type of periodontitis. There were no associated systemic signs and symptoms or any family history except that there was generalized vitiligo of the skin and oral mucous membrane. The case was treated by gross electrosection of the gingiva.

Genetic risk for psychiatric conditions encompass rare variants, identified due to major effect, as well as common variants, the latter analyzed by association analyses. We review guidelines for common variant association analyses, undertaking after assessing evidence of heritability. We highlight the importance of: suitably large sample sizes; an experimental design that controls for ancestry; careful data cleaning; correction for multiple testing; small P values for positive findings; assessment of effect size for positive findings; and, inclusion of an independent replication sample. We also note the importance of a critical discussion of any prior findings, biological follow-up where possible, and a means of accessing the raw data.

  19. Automated detection and association of surface waves

    C. R. D. Woodgold

    1994-06-01

    Full Text Available An algorithm for the automatic detection and association of surface waves has been developed and tested over an 18 month interval on broad band data from the Yellowknife array (YKA. The detection algorithm uses a conventional STA/LTA scheme on data that have been narrow band filtered at 20 s periods and a test is then applied to identify dispersion. An average of 9 surface waves are detected daily using this technique. Beamforming is applied to determine the arrival azimuth; at a nonarray station this could be provided by poIarization analysis. The detected surface waves are associated daily with the events located by the short period array at Yellowknife, and later with the events listed in the USGS NEIC Monthly Summaries. Association requires matching both arrival time and azimuth of the Rayleigh waves. Regional calibration of group velocity and azimuth is required. . Large variations in both group velocity and azimuth corrections were found, as an example, signals from events in Fiji Tonga arrive with apparent group velocities of 2.9 3.5 krn/s and azimuths from 5 to + 40 degrees clockwise from true (great circle azimuth, whereas signals from Kuriles Kamchatka have velocities of 2.4 2.9 km/s and azimuths off by 35 to 0 degrees. After applying the regional corrections, surface waves are considered associated if the arrival time matches to within 0.25 km/s in apparent group velocity and the azimuth is within 30 degrees of the median expected. Over the 18 month period studied, 32% of the automatically detected surface waves were associated with events located by the Yellowknife short period array, and 34% (1591 with NEIC events; there is about 70% overlap between the two sets of events. Had the automatic detections been reported to the USGS, YKA would have ranked second (after LZH in terms of numbers of associated surface waves for the study period of April 1991 to September 1992.

  20. Conceptual Association for Compound Noun Analysis

    CERN Document Server

    Lauer, M

    1994-01-01

    This paper describes research toward the automatic interpretation of compound nouns using corpus statistics. An initial study aimed at syntactic disambiguation is presented. The approach presented bases associations upon thesaurus categories. Association data is gathered from unambiguous cases extracted from a corpus and is then applied to the analysis of ambiguous compound nouns. While the work presented is still in progress, a first attempt to syntactically analyse a test set of 244 examples shows 75% correctness. Future work is aimed at improving this accuracy and extending the technique to assign semantic role information, thus producing a complete interpretation.

    Hyperkalaemia is associated with diabetes, but there are no recent reports of its prevalence and associations. Serum potassium concentrations were measured in all 1764 patients attending a diabetic clinic over a 12-month period and found to be > 5.0 mmol/l in 270 (15%), and > 5.4 mmol/l in 67 (4%). There was no other evident cause of hyperkalaemia in 41 of these 67 patients. These data serve to highlight the risk of dangerous hyperkalaemia in diabetic patients, particularly with concurrent ad...

    A new case of familial PHP, associated with polyglobulia and biochemical parameters of hyperaldosteronism has been described. This association represents a very rare entity. PHP has been documented by the common tests and the unresponsiveness of AMPc to PTH. The poliglobulia , which appears after a period of severe anaemia, needs now periodical blood subtraction; nevertheless a cerebral thrombosis with conseguent hemiparesis has recently occurred. The hyperaldosteronism has been documented by hypopotassiemia , a raised level of plasma aldosterone as well as suppressed plasma renin activity even after adequate stimulus. PMID:6374503

Cette association qui pose des problèmes diagnostiques est probablement fortuite du fait de l’absence de facteurs génétiques prédisposant partagés et du petit nombre des cas publiés, mais elle suggère l’hypothèse d’une liaison physiopathologique entre eux.

  5. Homocysteine increases the risk associated with hyperlipidaemia.

    LENUS (Irish Health Repository)

    Daly, Caroline

    2009-04-01

    The European Concerted Action Project \\'Homocysteine and Vascular Disease\\' showed that an elevated homocysteine is associated with a substantially increased risk of cardiovascular disease, and particularly when combined with other factors such as smoking, hypertension and hypercholesterolaemia. The purpose of this study was to examine the potential interactions between homocysteine and individual lipid subfractions. In addition, it was hypothesized that HDL cholesterol may protect against hyperhomocysteinaemia because HDL cholesterol is associated with the enzyme paroxonase, which reduces oxidization of homocysteine to the harmful metabolite, homocysteine thiolactonase.

    Pierre Robin sequence has been associated with a number of ocular complications, including myopia, strabismus, Möbius syndrome, nasolacrimal duct obstruction, glaucoma, cataract, microphthalmos, coloboma of choroid, and retinal detachment. We report a 10-day-old boy who presented with micrognathia, glossoptosis, and cleft palate as well as multiple congenital anomalies. Ophthalmic examination was notable for bilateral maculopathy, with focal areas of retinal and retinal pigment epithelial atrophy. The association of Pierre Robin sequence and maculopathy has been reported only twice previously.

    1989-01-01

    Convergence mechanism of vectors in the Hopfield's neural network is studied in terms of both weights (i.e., inner products) and Hamming distance. It is shown that Hamming distance should not always be used in determining the convergence of vectors. Instead, weights (which in turn depend on the neuron representation) are found to play a more dominant role in the convergence mechanism. Consequently, a new binary neuron representation for associative memory is proposed. With the new neuron representation, the associative memory responds unambiguously to the partial input in retrieving the stored information.

    Eccrine syringofibroadenoma is a rare benign neoplasia derived from acrosyryngium cells of the eccrine sudoriferous glands. It affects the extremities of elderly individuals as solitary tumors, or may also present as multiple lesions. There are controversies about the pathogenesis and differentiation of the tumor. Eccrine syringofibroadenoma has been associated with subjacent conditions, such as for example, hypohidrotic ectodermic dysplasias. The authors describe a case report of a patient with Clouston Syndrome, who presented papules and nodules in extremities, clinically and histologically compatible with eccrine syringofibroadenoma. There are only three cases described in the literature, associated with Clouston Syndrome, and this is the fourth case. PMID:24937830

    The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

    Tracheal anomalies are known in association with congenital cardiac defects. Some of the well-described anomalies include accessory (displaced) tracheal bronchus with variants, tracheal trifurcation and accessory cardiac bronchus. Here we describe a case of tracheal quadrifurcation associated with complex congenital heart disease. Illustration of complex airway anatomy was simplified by the use of multidetector CT using a variety of image display options. Awareness of this complex anomaly will expand our knowledge of tracheal anomalies and equip the anesthesia and surgical team for better airway management. (orig.)

    We call peacock an integrable process which is increasing in the convex order; such a notion plays an important role in Mathematical Finance. A deep theorem due to Kellerer states that a process is a peacock if and only if it has the same one-dimensional marginals as a martingale. Such a martingale is then said to be associated to this peacock. In this monograph, we exhibit numerous examples of peacocks and associated martingales with the help of different methods: construction of sheets, time reversal, time inversion, self-decomposability, SDE, Skorokhod embeddings!

    Genomewide association studies have identified numerous chronic kidney disease-associated genetic variants, but often do not pinpoint causal genes. This limitation was addressed by combining Mouse Genome Informatics with human genomewide association studies of kidney function. Genes for which mouse models showed abnormal renal physiology, morphology, glomerular filtration rate (GFR), or urinary albumin-to-creatinine ratio were identified from Mouse Genome Informatics. The corresponding human orthologs were then evaluated for GFR-associated single-nucleotide polymorphisms in 133,814 individuals and urinary albumin-to-creatinine ratio-associated SNPs in 54,451 individuals in genome-wide association studies meta-analysis of the CKDGen Consortium. After multiple testing corrections, significant associations with estimated GFR in humans were identified for single-nucleotide polymorphisms in 2, 7, and 17 genes causing abnormal GFR, abnormal physiology, and abnormal morphology in mice, respectively. Genes identified for abnormal kidney morphology showed significant enrichment for estimated GFR-associated single-nucleotide polymorphisms. In total, 19 genes contained variants associated with estimated GFR or the urinary albumin-to-creatinine ratio of which 16 mapped into previously reported genomewide significant loci. CYP26A1 and BMP4 emerged as novel signals subsequently validated in a large, independent study. An additional gene, CYP24A1, was discovered after conditioning on a published nearby association signal. Thus, our novel approach to combine comprehensive mouse phenotype information with human genomewide association studies data resulted in the identification of candidate genes for kidney disease pathogenesis.

    Glomerulonephritis (GN) due to infective endocarditis (IE) is well documented, but most available data are based on old autopsy series. To update information, we now present the largest biopsy-based clinicopathologic series on IE-associated GN. The study group included 49 patients (male-to-female ratio of 3.5:1) with a mean age of 48 years. The most common presenting feature was acute kidney injury. Over half of the patients had no known prior cardiac abnormality. However, the most common comorbidities were cardiac valve disease (30%), intravenous drug use (29%), hepatitis C (20%), and diabetes (18%). The cardiac valve infected was tricuspid in 43%, mitral in 33%, and aortic in 29% of patients. The two most common infective bacteria were Staphylococcus (53%) and Streptococcus (23%). Hypocomplementemia was found in 56% of patients tested and ANCA antibody in 28%. The most common biopsy finding was necrotizing and crescentic GN (53%), followed by endocapillary proliferative GN (37%). C3 deposition was prominent in all cases, whereas IgG deposition was seen in <30% of cases. Most patients had immune deposits detectable by electron microscopy. Thus, IE-associated GN most commonly presents with AKI and complicates staphylococcal tricuspid valve infection. Contrary to infection-associated glomerulonephritis in general, the most common pattern of glomerular injury in IE-associated glomerulonephritis was necrotizing and crescentic glomerulonephritis.

Production of Granulocyte-Colony Stimulating Factor, alpha-fetoprotein, paraneoplastic pemphigus and leucocytosis, Acrokeratosis paraneoplastica (Bazex's syndrome are reported. The present report describes a case of retroperitoneal liposarcoma associated with small plaque parapsoriasis. Our search in the English literature of such a kind of association did not reveal any case reported. Case presentation A 74 year male patient was admitted to our hospital because of the presence of an abdominal mass in right iliac fossa. He also complained of a two-year history of psoriasiform eruptions. The CT scan showed a retroperitoneal pelvic mass. Therefore surgical resection of the tumor was performed. After surgery, the skin eruptions disappeared completely in seven days and so a diagnosis of parapsoriasis syndrome was done. Conclusion Parallel disappearing of skin eruptions after surgery, typical clinical picture and not specific histology of the cutaneous lesions suggest the diagnosis of small plaque parapsoriasis. Therefore we propose to add Small Plaque Parapsoriasis to the list of paraneoplastic syndromes associated to liposarcoma.

    The constantly increasing volume and complexity of available biological data requires new methods for their management and analysis. An important challenge is the integration of information from different sources in order to discover possible hidden relations between already known data. In this paper we introduce a data mining approach which relates biological ontologies by mining cross and intra-ontology pairwise generalized association rules. Its advantage is sensitivity to rare associations, for these are important for biologists. We propose a new class of interestingness measures designed for hierarchically organized rules. These measures allow one to select the most important rules and to take into account rare cases. They favor rules with an actual interestingness value that exceeds the expected value. The latter is calculated taking into account the parent rule. We demonstrate this approach by applying it to the analysis of data from Gene Ontology and GPCR databases. Our objective is to discover interesting relations between two different ontologies or parts of a single ontology. The association rules that are thus discovered can provide the user with new knowledge about underlying biological processes or help improve annotation consistency. The obtained results show that produced rules represent meaningful and quite reliable associations.

  15. a Reliability Evaluation System of Association Rules

    Chen, Jiangping; Feng, Wanshu; Luo, Minghai

    2016-06-01

    In mining association rules, the evaluation of the rules is a highly important work because it directly affects the usability and applicability of the output results of mining. In this paper, the concept of reliability was imported into the association rule evaluation. The reliability of association rules was defined as the accordance degree that reflects the rules of the mining data set. Such degree contains three levels of measurement, namely, accuracy, completeness, and consistency of rules. To show its effectiveness, the "accuracy-completeness-consistency" reliability evaluation system was applied to two extremely different data sets, namely, a basket simulation data set and a multi-source lightning data fusion. Results show that the reliability evaluation system works well in both simulation data set and the actual problem. The three-dimensional reliability evaluation can effectively detect the useless rules to be screened out and add the missing rules thereby improving the reliability of mining results. Furthermore, the proposed reliability evaluation system is applicable to many research fields; using the system in the analysis can facilitate obtainment of more accurate, complete, and consistent association rules.

    2010-12-01

    Full Text Available The purpose of the present study was to assess the association between overbite and craniofacial growth pattern. The sample comprised eighty-six cephalograms obtained during the orthodontic pretreatment phase and analyzed using the Radiocef program to identify the craniofacial landmarks and perform orthodontic measurements. The variables utilized were overbite, the Jarabak percentage and the Vert index, as well as classifications resulting from the interpretation of these measurements. In all the statistical tests, a significance level of 5% was considered. Measurement reliability was checked by calculating method error. Weighted Kappa analysis showed that agreement between the facial types defined by the Vert index and the direction of growth trend established by the Jarabak percentage was not satisfactory. Owing to this lack of equivalency, a potential association between overbite and craniofacial growth pattern was evaluated using the chi-square test, considering the two methods separately. No relationship of dependence between overbite and craniofacial growth pattern was revealed by the results obtained. Therefore, it can be concluded that the classification of facial growth pattern will not be the same when considering the Jarabak and the Ricketts anayses, and that increased overbite cannot be associated with a braquifacial growth pattern, nor can openbite be associated with a dolichofacial growth pattern.

    Introduction: Transperineal prostate brachytherapy is gaining popularity as a treatment for clinically localized carcinoma of the prostate. Very little prospective data exists addressing the issue of complications associated with this procedure. We present an analysis of the early voiding dysfunction associated with prostate brachytherapy. Materials and Methods: Forty-six consecutive patients who underwent Palladium-103 (Pd-103) seed placement for clinically localized prostate carcinoma were evaluated prospectively for any morbidity associated with the procedure. Twenty-three patients completed an International Prostate Symptom Score (IPSS) questionnaire preoperatively, at their first postoperative visit, and at their second postoperative visit. The total IPSS, each of the seven individual components, and the "bother" score were evaluated separately for each visit, and statistical significance was determined. Results: Urinary retention occurred in 7/46 patients (15%). Of these, 5 were able to void spontaneously after catheter removal. One patient is maintained with a suprapubic tube, and one patient is currently on continuous intermittent catheterization. Baseline IPSS was 7.1 and this went to 20.0 at the first postoperative visit (p<0.001). By the second postoperative visit, the IPSS was 8.0. Conclusions: In our experience, prostate brachytherapy for localized carcinoma of the prostate is associated with a 15% catheterization rate and a significant increase in the IPSS (7.1 to 20.0). This increase in the IPSS seems to be self-limited. Patients need to be educated on these issues prior to prostate brachytherapy. PMID:11113369

  11. Evolution of associative learning in chemical networks.

    Directory of Open Access Journals (Sweden)

    Simon McGregor

    Full Text Available Organisms that can learn about their environment and modify their behaviour appropriately during their lifetime are more likely to survive and reproduce than organisms that do not. While associative learning - the ability to detect correlated features of the environment - has been studied extensively in nervous systems, where the underlying mechanisms are reasonably well understood, mechanisms within single cells that could allow associative learning have received little attention. Here, using in silico evolution of chemical networks, we show that there exists a diversity of remarkably simple and plausible chemical solutions to the associative learning problem, the simplest of which uses only one core chemical reaction. We then asked to what extent a linear combination of chemical concentrations in the network could approximate the ideal Bayesian posterior of an environment given the stimulus history so far? This Bayesian analysis revealed the 'memory traces' of the chemical network. The implication of this paper is that there is little reason to believe that a lack of suitable phenotypic variation would prevent associative learning from evolving in cell signalling, metabolic, gene regulatory, or a mixture of these networks in cells.

    This study examined the effects of acute, isocaloric aerobic and resistance exercise on different sleep parameters, and whether changes in these sleep parameters between sessions were related to next morning food reward. Fourteen men and women (age: 21.9 ± 2.7 years; body mass index: 22.7 ± 1.9 kg m(-) ²) participated in three randomized crossover sessions: aerobic exercise; resistance exercise; and sedentary control. Target exercise energy expenditure was matched at 4 kcal kg(-1) of body weight, and performed at 70% of VO2peak or 70% of 1 repetition-maximal. Sleep was measured (accelerometry) for 22 h following each session. The 'wanting' for visual food cues (validated computer task) was assessed the next morning. There were no differences in sleep parameters and food 'wanting' between conditions. Decreases in sleep duration and earlier wake-times were significantly associated with increased food 'wanting' between sessions (P = 0.001). However, these associations were no longer significant after controlling for elapsed time between wake-time and the food reward task. These findings suggest that shorter sleep durations and earlier wake-times are associated with increased food reward, but these associations are driven by elapsed time between awakening and completion of the food reward task.

    Full Text Available Objective: To identify the prevalence of osteoporosis in postmenopausal women who conducted their examinations of Bone Mineral Densitometry in private clinic in the city of Maringá (PR in the years of 2012 and 2013 and their association with risk factors. Methods: This transversal, descriptive exploratory study involving 177 postmenopausal women. The study included patients who presented primary osteoporosis, with or without hysterectomy and excluded volunteers who presented other conditions or diseases associated with altered bone mass. The main analyzed variables were: race; Body Mass Index; ages of menarche and menopause and menopause time. Results: The average age of the sample was 59 years old with a standard deviation of ±7.97 years. In relation to the classification of the patients according to the results of the examination of bone mass, 23% were in the normal group, 65% presented osteopenia and 12%, osteoporosis. Statistical analysis showed association of advanced age and time of menopause with the disease, but there was no statistical significance in relation to the analysis for association of other risk factors. Conclusions: The study conducted allows to conclude that there was a low prevalence of normal densitometry and high prevalence of low bone mass in the sampling population. The age and menopausal time period can be considered as risk factors for osteoporosis in the sample.

    2016-01-01

    Growing data show the association of metabolic syndrome (MetS) or its components with cancer development and cancer-related mortality. It is suggested that in MetS and cancer association, insulin resistance and insulin-like growth factor 1 system play a key role, especially adipokines secreted from visceral adipocytes, free fatty acids and aromatase activity contribute to this process. It is also reported that MetS has a link with colorectal, breast, endometrial, pancreas, primary liver and, although controversial, prostate cancer. Although every component of MetS is known to have an association with cancer development, it is still debated whether the effects of these components are additive or synergistic. On the other hand, in the association between MetS and cancer, the role of antidiabetic and antihypertensive treatments including thiazolidinedione, insulin, angiotensin receptor blockers is also suggested. The primary approach in MetS-cancer relation is to prevent risk factors. Life style changes including weight loss and a healthy diet are known to decrease cancer risk in normal population. It is postulated that an insulin-sensitizing agent, metformin, has cancer-preventing effects on diabetic patients. This review discusses the relationship between MetS and cancer from different aspects and examines this relationship in some of the cancers suggested to be linked with MetS. PMID:26895247

    Stallings, Tiffany L

    2008-06-01

    This paper critically reviews the association of infection by Chlamydophila pneumoniae (C. pneumoniae) and Alzheimer's disease (AD). The aging population has increased interest in finding the cause of AD, but studies have yielded contradictory results that are likely due to varying diagnostic tools and different uses of diagnostic tests. Knowledge of AD's characteristics, risk factors, and hypothesized etiologies has expanded since Alois Alzheimer's initial description of AD. Epidemiologic and projection studies provide incidence estimates of AD through a two-stage method: (1) primary diagnosis of dementia by cognitive testing such as Mini-Mental State Examination (MMSE), and (2) clinical diagnosis of AD through criteria such as National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA). Cross-sectional studies yield prevalence estimates of infection by C. pneumoniae by detecting immunoglobulins through laboratory tests such as microimmunofluorescence (MIF). Studies examining the association of C. pneumoniae and AD are limited, but brain autopsy provides information about presence, proximity to areas associated with AD, and bacterial load. Standardization of diagnostic techniques would allow for better comparability of studies, but uncertainty about the best method of diagnosis of infection by C. pneumoniae and AD may call for revised or novel diagnostic tools.

  16. Chromatin associations in Arabidopsis interphase nuclei

    Directory of Open Access Journals (Sweden)

    Veit eSchubert

    2014-11-01

    Full Text Available The arrangement of chromatin within interphase nuclei seems to be caused by topological constraints and related to gene expression depending on tissue and developmental stage. In yeast and animals it was found that homologous and heterologous chromatin association are required to realize faithful expression and DNA repair. To test whether such associations are present in plants we analysed Arabidopsis thaliana interphase nuclei by FISH using probes from different chromosomes. We found that chromatin fibre movement and variable associations, although in general relatively seldom, may occur between euchromatin segments along chromosomes, sometimes even over large distances. The combination of euchromatin segments bearing high or low co-expressing genes did not reveal different association frequencies probably due to adjacent genes of deviating expression patterns.Based on previous data and on FISH analyses presented here, we conclude that the global interphase chromatin organization in A. thaliana is relatively stable, due to the location of its ten centromeres at the nuclear periphery and of the telomeres mainly at the centrally localized nucleolus. Nevertheless, chromatin movement enables a flexible spatial genome arrangement in plant nuclei.

  19. Figure-associated text summarization and evaluation.

    Directory of Open Access Journals (Sweden)

    Balaji Polepalli Ramesh

    Full Text Available Biomedical literature incorporates millions of figures, which are a rich and important knowledge resource for biomedical researchers. Scientists need access to the figures and the knowledge they represent in order to validate research findings and to generate new hypotheses. By themselves, these figures are nearly always incomprehensible to both humans and machines and their associated texts are therefore essential for full comprehension. The associated text of a figure, however, is scattered throughout its full-text article and contains redundant information content. In this paper, we report the continued development and evaluation of several figure summarization systems, the FigSum+ systems, that automatically identify associated texts, remove redundant information, and generate a text summary for every figure in an article. Using a set of 94 annotated figures selected from 19 different journals, we conducted an intrinsic evaluation of FigSum+. We evaluate the performance by precision, recall, F1, and ROUGE scores. The best FigSum+ system is based on an unsupervised method, achieving F1 score of 0.66 and ROUGE-1 score of 0.97.

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    AIM: To examine the association between obesity and gastropharyngeal reflux disease (GPRD) as well as gastroesophageal reflux disease (GERD)METHODS: We conducted a cross-sectional study of consecutive patients undergoing ambulatory 24-h dual-probe pH monitoring from July 2003 to December 2006.The association between body mass index (BMI) and parameters about gastroesophageal or gastropharyngeal reflux was examined in univariate and multivariate analyses.RESULTS: A total of 769 patients (307 men and 462 women; mean age 50.7 years) were finally enrolled. Most variables showing gastroesophageal reflux was higher in the obese patients than the patients with normal BMI.There was no difference in all the variables showing gastropharyngeal reflux according to the BMI. After adjustment for age, sex, alcohol intake and smoking,obese patients demonstrated an about 2-fold increase in risk of GERD compared with patients with normal BMI (OR, 1.9; 95 CI, 1.3-2.9), but overweight patients did not demonstrate increased risk of GERD (OR, 1.2; 95 CI,0.8-1.7). Both obese patients and overweight patients did not demonstrated increased risk of GPRD compared with patients with normal BM[ (OR, 1.1; 95 CI, 0.8-1.7;and OR, 0.9; 95 CI, 0.6-1.3, respectively).CONCLUSION: Obesity is not associated with GPRD reflux while it is associated with GERD.

    Arsenic poisoning is an often unrecognized cause of renal insufficiency. We report a case of tubulointerstitial nephritis associated with an elevated urinary arsenic concentration. Removal of the putative source of arsenic resulted in symptomatic improvement, resolution of abnormal abdominal radiographs, and stabilization of renal function. This case emphasizes the importance of heavy metal screening in patients with multisystem complaints and tubulointerstitial nephritis.

    Full Text Available Background. The goal of this paper was to examine neighborhood deprivation and prostate cancer severity. Methods. We studied African American and Caucasian prostate cancer cases from the Pennsylvania State Cancer Registry. Census tract-level variables and deprivation scores were examined in relation to diagnosis stage, grade, and tumor aggressiveness. Results. We observed associations of low SES with high Gleason score among African Americans residing in neighborhoods with low educational attainment (OR = 1.34, 95% CI = 1.13–1.60, high poverty (OR = 1.39, 95% CI = 1.15–1.67, low car ownership (OR = 1.46, 95% CI = 1.20–1.78, and higher percentage of residents on public assistance (OR = 1.32, 95% = 1.08–1.62. The highest quartile of neighborhood deprivation was also associated with high Gleason score. For both Caucasians and African Americans, the highest quartile of neighborhood deprivation was associated with high Gleason score at diagnosis (OR = 1.34, 95% CI = 1.19–1.52; OR = 1.71, 95% CI = 1.21–2.40, resp.. Conclusion. Using a neighborhood deprivation index, we observed associations between high-grade prostate cancer and neighborhood deprivation in Caucasians and African-Americans.

    This study aims to determine the microbiological quality of particulate matter (PM) in an urban area in Jeddah, Saudi Arabia, during December 2012 to April 2013. This was achieved by the determination of airborne bacteria, fungi, and actinobacteria associated PM10 and PM2.5, as well as their relationships with gaseous pollutants, O3, SO2 and NO2, and meteorological factors (T°C, RH% and Ws). High volume samplers with PM10 and PM2.5 selective sizes, and glass fiber filters were used to collect PM10 and PM2.5, respectively. The filters were suspended in buffer phosphate and aliquots were spread plated onto the surfaces of trypticase soy agar, malt extract agar, and starch casein agar media for counting of bacteria, fungi and actinobacteria-associated PM, respectively. PM10 and PM2.5 concentrations averaged 159.9 μg/m(3) and 60 μg/m(3), respectively, with the ratio of PM2.5/PM10 averaged ~0.4. The concentrations of O3, SO2 and NO2 averaged 35.73 μg/m(3), 38.1μg/m(3) and 52.5 μg/m(3), respectively. Fungi and actinobacteria associated PM were found in lower concentrations than bacteria. The sum of microbial loads was higher in PM10 than PM2.5, however a significant correlation (r=0.57, P ≤ 0.05) was found between the sum of microbial loads associated PM10 and PM2.5. Aspergillus fumigatus and Aspergillus niger were the common fungal types associated PM. Temperature significantly correlated with both PM10 (r=0.44), and PM2.5 (r=0.5). Significant negative correlations were found between O3 and PM2.5 (r=-0.47), and between SO2 with PM10 (r=-0.48). Wind speed positively correlated with airborne microorganisms associated PM. The regression model showed that the inverse PM2.5 concentration (1/PM2.5) was a significant determinant of fungal count associated PM. Chemical processes and environmental factors could affect properties of PM and in turn its biological quality.

    Height is a classic complex trait with common variants in a growing list of genes known to contribute to the phenotype. Using a genecentric genotyping array targeted toward cardiovascular-related loci, comprising 49,320 SNPs across approximately 2000 loci, we evaluated the association of common and uncommon SNPs with adult height in 114,223 individuals from 47 studies and six ethnicities. A total of 64 loci contained a SNP associated with height at array-wide significance (p < 2.4 × 10−6), with 42 loci surpassing the conventional genome-wide significance threshold (p < 5 × 10−8). Common variants with minor allele frequencies greater than 5% were observed to be associated with height in 37 previously reported loci. In individuals of European ancestry, uncommon SNPs in IL11 and SMAD3, which would not be genotyped with the use of standard genome-wide genotyping arrays, were strongly associated with height (p < 3 × 10−11). Conditional analysis within associated regions revealed five additional variants associated with height independent of lead SNPs within the locus, suggesting allelic heterogeneity. Although underpowered to replicate findings from individuals of European ancestry, the direction of effect of associated variants was largely consistent in African American, South Asian, and Hispanic populations. Overall, we show that dense coverage of genes for uncommon SNPs, coupled with large-scale meta-analysis, can successfully identify additional variants associated with a common complex trait.

    Each of the two moving observers observes the relative velocity of the other. The two velocities should be equal and opposite. We have shown that this relativistic requirement is not fulfilled by Lorentz transformation. We have also shown that the reason is that Lorentz transformation is not associative. Reciprocal symmetric transformation is associative and fulfills relativistic requirements.

    Usual sleep duration is a heritable trait correlated with psychiatric morbidity, cardiometabolic disease and mortality, although little is known about the genetic variants influencing this trait. A genome-wide association study (GWAS) of usual sleep duration was conducted using 18 population-based cohorts totaling 47 180 individuals of European ancestry. Genome-wide significant association was identified at two loci. The strongest is located on chromosome 2, in an intergenic region 35- to 80-kb upstream from the thyroid-specific transcription factor PAX8 (lowest P=1.1 × 10(-9)). This finding was replicated in an African-American sample of 4771 individuals (lowest P=9.3 × 10(-4)). The strongest combined association was at rs1823125 (P=1.5 × 10(-10), minor allele frequency 0.26 in the discovery sample, 0.12 in the replication sample), with each copy of the minor allele associated with a sleep duration 3.1 min longer per night. The alleles associated with longer sleep duration were associated in previous GWAS with a more favorable metabolic profile and a lower risk of attention deficit hyperactivity disorder. Understanding the mechanisms underlying these associations may help elucidate biological mechanisms influencing sleep duration and its association with psychiatric, metabolic and cardiovascular disease.

    While progress has been made in identifying common genetic variants associated with human diseases, for most of common complex diseases, the identified genetic variants only account for a small proportion of heritability. Challenges remain in finding additional unknown genetic variants predisposing to complex diseases. With the advance in next-generation sequencing technologies, sequencing studies have become commonplace in genetic research. The ongoing exome-sequencing and whole-genome-sequencing studies generate a massive amount of sequencing variants and allow researchers to comprehensively investigate their role in human diseases. The discovery of new disease-associated variants can be enhanced by utilizing powerful and computationally efficient statistical methods. In this paper, we propose a functional analysis of variance (FANOVA) method for testing an association of sequence variants in a genomic region with a qualitative trait. The FANOVA has a number of advantages: (1) it tests for a joint effect of gene variants, including both common and rare; (2) it fully utilizes linkage disequilibrium and genetic position information; and (3) allows for either protective or risk-increasing causal variants. Through simulations, we show that FANOVA outperform two popularly used methods - SKAT and a previously proposed method based on functional linear models (FLM), - especially if a sample size of a study is small and/or sequence variants have low to moderate effects. We conduct an empirical study by applying three methods (FANOVA, SKAT and FLM) to sequencing data from Dallas Heart Study. While SKAT and FLM respectively detected ANGPTL 4 and ANGPTL 3 associated with obesity, FANOVA was able to identify both genes associated with obesity. PMID:25244256

    Concluding remarks about this paper are: (1) Gravitational settling, zeta potential, and ultrafiltration data indicate the existence of a colloidal phase of both the alpha and beta emitters in the Chancellor water; (2) The low activity combined with high dispersion homogeneity of the Chancellor water indicate that both alpha and beta emitters are not intrinsic colloids; (3) Radionuclides in the Chancellor water, particularly Pu, coexist as dissolved aqueous and sorbed phases - in other words the radionuclides are partitioned between the aqueous phase and the colloidal phase; (4) The presence of Pu as a dissolved species in the aqueous phase, suggests the possibility of Pu in the (V) oxidation state - this conclusion is supported by the similarity of the k{sub d} value of Pu determined in the current study to that determined for Pu(V) sorbed onto smectite colloids, and the similar electrokinetic behavior of the Chancellor water colloids to smectite colloids; (5) About 50% of the Pu(V) is in the aqueous phase and 50% is sorbed on colloids (mass concentration of colloids in the Chancellor water is 0.12 g/L); (6) The k{sub d} of the Pu and the beta emitters (fission products) between aqueous and colloidal phases in the Chancellor water is {approx}8.0 x 10{sup 3} mL/g using two different activity measurement techniques (LSC and alpha spectroscopy); (7) The gravitational settling and size distributions of the association colloids indicate that the properties (at least the physical ones) of the colloids to which the alpha emitters are associated with seem to be different that the properties of the colloids to which the beta emitters are associated with - the beta emitters are associated with very small particles ({approx}50 - 120 nm), while the alpha emitters are associated with relatively larger particles; and (8) The Chancellor water colloids are extremely stable under the natural pH and ionic strength conditions, indicating high potential for transport in the

    Full Text Available Natural objects provide partially redundant information to the brain through different sensory modalities. For example, voices and faces both give information about the speech content, age, and gender of a person. Thanks to this redundancy, multimodal recognition is fast, robust, and automatic. In unimodal perception, however, only part of the information about an object is available. Here, we addressed whether, even under conditions of unimodal sensory input, crossmodal neural circuits that have been shaped by previous associative learning become activated and underpin a performance benefit. We measured brain activity with functional magnetic resonance imaging before, while, and after participants learned to associate either sensory redundant stimuli, i.e. voices and faces, or arbitrary multimodal combinations, i.e. voices and written names, ring tones, and cell phones or brand names of these cell phones. After learning, participants were better at recognizing unimodal auditory voices that had been paired with faces than those paired with written names, and association of voices with faces resulted in an increased functional coupling between voice and face areas. No such effects were observed for ring tones that had been paired with cell phones or names. These findings demonstrate that brief exposure to ecologically valid and sensory redundant stimulus pairs, such as voices and faces, induces specific multisensory associations. Consistent with predictive coding theories, associative representations become thereafter available for unimodal perception and facilitate object recognition. These data suggest that for natural objects effective predictive signals can be generated across sensory systems and proceed by optimization of functional connectivity between specialized cortical sensory modules.

    Full Text Available Steven Lehrer, Sheryl Green, John A Martignetti, Kenneth E Rosenzweig Departments of Radiation Oncology and Genetics and Genomic Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA Background: The risk of thyroid cancer is known to be slightly increased in women after treatment for breast cancer. In the current study, we analyzed the incidence of thyroid cancer and breast cancer in 50 US states and in the District of Columbia to ascertain how often these two diseases are associated. Methods: Data on the incidence of thyroid cancer were obtained from the Centers for Disease Control and Prevention and the National Cancer Institute and data on the incidence of breast cancer were from the American Cancer Society. Data on the average number of children per family with children and mean household income were sourced from the US Bureau of the Census and prevalence of obesity by state is determined from a paper published in 2010 on state-specific obesity prevalence among US adults by the Centers for Disease Control and Prevention. Results: There was a significant association between breast and thyroid cancer (P=0.002. Since the incidence of breast cancer increases with increasing income and obesity, while decreasing with parity, multiple linear regression was performed. Breast cancer incidence was significantly related to thyroid cancer incidence (β=0.271, P=0.039, inversely related to average number of children per family with children (β=-0.271, P=0.039, unrelated to adult obesity (β=0.134, P=0.369, and significantly related to family income (β=0.642, P<0.001. Conclusion: This study identifies an association between breast and thyroid cancer. The association suggests that unexplored breast-thyroid cancer susceptibility loci exist and warrant further study.

  2. Celiac Disease and Autoimmune-Associated Conditions

    Full Text Available Celiac disease (CD is frequently accompanied by a variety of extradigestive manifestations, thus making it a systemic disease rather than a disease limited to the gastrointestinal tract. This is primarily explained by the fact that CD belongs to the group of autoimmune diseases. The only one with a known etiology is related to a permanent intolerance to gluten. Remarkable breakthroughs have been achieved in the last decades, due to a greater interest in the diagnosis of atypical and asymptomatic patients, which are more frequent in adults. The known presence of several associated diseases provides guidance in the search of oligosymptomatic cases as well as studies performed in relatives of patients with CD. The causes for the onset and manifestation of associated diseases are diverse; some share a similar genetic base, like type 1 diabetes mellitus (T1D; others share pathogenic mechanisms, and yet, others are of unknown nature. General practitioners and other specialists must remember that CD may debut with extraintestinal manifestations, and associated illnesses may appear both at the time of diagnosis and throughout the evolution of the disease. The implementation of a gluten-free diet (GFD improves the overall clinical course and influences the evolution of the associated diseases. In some cases, such as iron deficiency anemia, the GFD contributes to its disappearance. In other disorders, like T1D, this allows a better control of the disease. In several other complications and/or associated diseases, an adequate adherence to a GFD may slow down their evolution, especially if implemented during an early stage.

    Full Text Available Abstract Background Multiple sclerosis (MS is an immune-mediated disease of polygenic etiology. Dissection of its genetic background is a complex problem, because of the combinatorial possibilities of gene-gene interactions. As genotyping methods improve throughput, approaches that can explore multigene interactions appropriately should lead to improved understanding of MS. Methods 286 unrelated patients with definite MS and 362 unrelated healthy controls of Russian descent were genotyped at polymorphic loci (including SNPs, repeat polymorphisms, and an insertion/deletion of the DRB1, TNF, LT, TGFβ1, CCR5 and CTLA4 genes and TNFa and TNFb microsatellites. Each allele carriership in patients and controls was compared by Fisher's exact test, and disease-associated combinations of alleles in the data set were sought using a Bayesian Markov chain Monte Carlo-based method recently developed by our group. Results We identified two previously unknown MS-associated tri-allelic combinations: -509TGFβ1*C, DRB1*18(3, CTLA4*G and -238TNF*B1,-308TNF*A2, CTLA4*G, which perfectly separate MS cases from controls, at least in the present sample. The previously described DRB1*15(2 allele, the microsatellite TNFa9 allele and the biallelic combination CCR5Δ32, DRB1*04 were also reidentified as MS-associated. Conclusion These results represent an independent validation of MS association with DRB1*15(2 and TNFa9 in Russians and are the first to find the interplay of three loci in conferring susceptibility to MS. They demonstrate the efficacy of our approach for the identification of complex-disease-associated combinations of alleles.

    The excess Helmholtz free energy functional for associating Lennard-Jones (LJ) fluid is formulated in terms of a weighted density approximation for short-ranged interactions and a Weeks Chandler-Andersen approximation for long-range attraction. Within the framework of density functional theory, phase equilibria, vapour-liquid surface tension and vapour-liquid nucleation properties including the density profile, work of formation, excess number of particles and critical supersaturation are investigated for associating LJ fluids with different numbers of association sites (M=1,2,3,4) per particle. The influences of association energy and association sites on phase equilibria, surface tension and vapour-liquid nucleation properties are discussed.

  8. A genome wide association study identifies common variants associated with lipid levels in the Chinese population.

    Full Text Available Plasma lipid levels are important risk factors for cardiovascular disease and are influenced by genetic and environmental factors. Recent genome wide association studies (GWAS have identified several lipid-associated loci, but these loci have been identified primarily in European populations. In order to identify genetic markers for lipid levels in a Chinese population and analyze the heterogeneity between Europeans and Asians, especially Chinese, we performed a meta-analysis of two genome wide association studies on four common lipid traits including total cholesterol (TC, triglycerides (TG, low-density lipoprotein cholesterol (LDL and high-density lipoprotein cholesterol (HDL in a Han Chinese population totaling 3,451 healthy subjects. Replication was performed in an additional 8,830 subjects of Han Chinese ethnicity. We replicated eight loci associated with lipid levels previously reported in a European population. The loci genome wide significantly associated with TC were near DOCK7, HMGCR and ABO; those genome wide significantly associated with TG were near APOA1/C3/A4/A5 and LPL; those genome wide significantly associated with LDL were near HMGCR, ABO and TOMM40; and those genome wide significantly associated with HDL were near LPL, LIPC and CETP. In addition, an additive genotype score of eight SNPs representing the eight loci that were found to be associated with lipid levels was associated with higher TC, TG and LDL levels (P = 5.52 × 10(-16, 1.38 × 10(-6 and 5.59 × 10(-9, respectively. These findings suggest the cumulative effects of multiple genetic loci on plasma lipid levels. Comparisons with previous GWAS of lipids highlight heterogeneity in allele frequency and in effect size for some loci between Chinese and European populations. The results from our GWAS provided comprehensive and convincing evidence of the genetic determinants of plasma lipid levels in a Chinese population.

    Open calcaneus fractures are usually the result of high-energy mechanisms and are associated with other orthopedic and whole body system injures. Understanding the difference between open versus closed fractures is essential for the provider, and they must be vigilant for the associated injuries that present with this condition. We performed a retrospective medical record review of 62 patients (64 calcaneus fractures) with open calcaneus fractures from January 2003 to January 2013 presenting at a level 1 trauma center. Sex, age, laterality, mechanism of injury, wound appearance, initial management, and associated injures were recorded. The most common mechanisms were motor vehicle accidents (35 [56.4%]) and falls from >6 ft (15 [24.1%]). Four (6.4%) patients had a posterior tibial artery transection. Eight (12.9%) patients had a femoral shaft fracture, 14 (22.5%) an ipsilateral ankle fracture, 16 (25.8%) a metatarsal fracture, and 11 (17.7%) had associated midfoot fractures. Of the midfoot fractures, 12 (19.3%) patients had a talus fracture and 5 (8.0%) a cuboid fracture. Spinal fractures were present in 9 (14.5%) of the patients, with lumbar fractures occurring in 6 (9.6%) patients. Fifteen (24.1%) patients had associated upper extremity fractures. Thirteen (20.9%) patients had an associated pulmonary injury, including 8 pneumothoraces. Ten (16.1%) patients had a closed head injury and 6 (9.6%) had an abdominal injury. Fifteen (23.4%) patients were treated with percutaneous wire fixation and 7 (10.9%) with open reduction internal fixation. A total of 44 (68.7%) fractures were treated without internal fixation. Overall, 5 (8.0%) patients with an open calcaneus fracture eventually underwent a below-the-knee amputation. Open calcaneus fractures are severe, high-energy injuries with the potential for considerable morbidity to the patient, given the high rate of concomitant orthopedic and whole body system injuries. Type III open injuries have an increased risk of

    2009-08-01

    Full Text Available Abstract Background For membrane proteins, lipids provide a structural framework and means to modulate function. Paired connexin hemichannels form the intercellular channels that compose gap junction plaques while unpaired hemichannels have regulated functions in non-junctional plasma membrane. The importance of interactions between connexin channels and phospholipids is poorly understood. Results Endogenous phospholipids most tightly associated with purified connexin26 or connexin32 hemichannels or with junctional plaques in cell membranes, those likely to have structural and/or modulatory effects, were identified by tandem electrospray ionization-mass spectrometry using class-specific interpretative methods. Phospholipids were characterized by headgroup class, charge, glycerol-alkyl chain linkage and by acyl chain length and saturation. The results indicate that specific endogenous phospholipids are uniquely associated with either connexin26 or connexin32 channels, and some phospholipids are associated with both. Functional effects of the major phospholipid classes on connexin channel activity were assessed by molecular permeability of hemichannels reconstituted into liposomes. Changes to phospholipid composition(s of the liposome membrane altered the activity of connexin channels in a manner reflecting changes to the surface charge/potential of the membrane and, secondarily, to cholesterol content. Together, the data show that connexin26 and connexin32 channels have a preference for tight association with unique anionic phospholipids, and that these, independent of headgroup, have a positive effect on the activity of both connexin26 and connexin32 channels. Additionally, the data suggest that the likely in vivo phospholipid modulators of connexin channel structure-function that are connexin isoform-specific are found in the cytoplasmic leaflet. A modulatory role for phospholipids that promote negative curvature is also inferred. Conclusion

  12. Valvular disease associated with systemic illness.

    1998-08-01

    The connective tissue diseases are immune-mediated inflammatory diseases that manifest predominantly with symptoms and signs of musculoskeletal and mucocutaneous inflammation. They frequently affect the heart valves, pericardium, and myocardium. In patients with AKS, the aortic root and conduction system are also frequently involved. Echocardiographic series in these patients have demonstrated that valvular disease is highly prevalent and associated with substantial morbidity and mortality (Table 1). The prevalence rates of clinically detected valvular disease, however, are either unknown or low. This discrepancy is related to lack of awareness, overshadowing of the cardiovascular manifestations by the inflammatory symptoms and signs of the musculoskeletal system, lack of systematic application of the history and cardiovascular physical examination, and high sensitivity of echocardiography for detecting subclinical abnormalities. Several valvular abnormalities have been identified as unique to a specific disease. Libman-Sacks vegetations, valve nodules, and subaortic bump are characteristic of SLE, RA, and AKS (see Table 1). The valvular complications and respective therapy are similar to those of other causes of valvular disease; however, the associated morbidity and mortality of these complications in these patients are high. The worse prognosis of valvular disease in these patients is related to the chronicity and debilitating nature of their illness, their high prevalence of multisystem disease, and immunosuppression. These factors underscore the importance of early recognition, prevention of complications, and proper clinical or echocardiographic follow-up. The distinctive echocardiographic characteristics of the valve abnormalities associated with the connective tissue diseases may allow their differentiation from other common valvulopathies, such as infective endocarditis, rheumatic valvular disease, and degenerative valvular disease (Table 2).

    Pepper spray containing oleoresin capsicum is used by law enforcement and the public as a form of nonlethal deterrent. Stimulated by the identification of a case of a corneal abrasion associated with pepper spray exposure, a descriptive retrospective review of a physician-maintained log of patients presenting to a jail ward emergency area over a 3-year period was performed. The objective was to give some quantification to the frequency with which an emergency physician could expect to see corneal abrasions associated with pepper spray exposure. Of 100 cases of pepper spray exposure identified, seven patients had sustained corneal abrasions. We conclude that corneal abrasions are not rare events when patients are exposed to pepper spray and that fluorescein staining and slit lamp or Wood's lamp examination should be performed on all exposed patients in whom corneal abrasions cannot be excluded on clinical grounds.

    1978-01-01

    Actinomyces viscosus ATCC 15987 was examined for the presence of cell-associated levan by absorption of myeloma proteins with antilevan activity and direct immunofluorescence. Levan was not detectable on the surface of glucose-grown A. viscosus, but after a brief incubation of these cells with 5% sucrose, they were encapsulated with tenaciously adhering levan. The levan layer constituted between 0.02 and 0.03% of the cell dry weight. In contrast, sucrose-grown A. viscosus cells possessed a low level of cell-associated levan, which was only moderately increased by incubation in sucrose and which partially existed as a loose slime rather than a tenacious capsule.

    Introduction Citrobacter koseri is a well known cause of central nervous system infections in the paediatric setting. Musculoskeletal infections caused by C koseri are rare, with only 14 previously reported cases. We present the first recorded case of C koseri induced septic arthritis of the knee along with a review of the literature. Methods A search of the PubMed, Embase(®) and Google Scholar™ databases was undertaken. Only complete or near complete cases were reviewed. Findings Fourteen musculoskeletal infections were identified. Of these, five were associated with an operative procedure and five involved a septic joint. Surgical treatment was required in the majority of cases and cure was achieved in all cases following prolonged antibiotic use. Conclusions C koseri associated musculoskeletal infections may complicate primary orthopaedic procedures. The organism can present aggressively and can be difficult to identify microbiologically. It is sensitive to newer generation beta-lactams, cephalosporin-based antibiotics and timely surgery.

  20. Biomolecule surface patterning may enhance membrane association

    2012-01-01

    Under dehydration conditions, amphipathic Late Embryogenesis Abundant (LEA) proteins fold spontaneously from a random conformation into alpha-helical structures and this transition is promoted by the presence of membranes. To gain insight into the thermodynamics of membrane association we model the resulting alpha-helical structures as infinite rigid cylinders patterned with hydrophobic and hydrophilic stripes oriented parallel to their axis. Statistical thermodynamic calculations using Single Chain Mean Field (SCMF) theory show that the relative thickness of the stripes controls the free energy of interaction of the alpha-helices with a phospholipid bilayer, as does the bilayer structure and the depth of the equilibrium penetration of the cylinders into the bilayer. The results may suggest the optimal thickness of the stripes to mimic the association of such protein with membranes.

    Full Text Available Cancerous patients, under the chemotherapy or radiotherapy, are at high risk of malnutrition due to the associated complications with the treatment procedures such as chewing problems, dysphagia, nausea etc. Considering the patients’ history of alcohol consumption, smoking or any other diseases and performing several physical examinations are essential in early identification of high-risk patients for nutritional complications, losing unintentional weight and fat free mass. In this review, we tried to briefly explain the risk of malnutrition in patients with head and neck cancers who are undergoing surgery, chemotherapy and radiotherapy. Oral nutrition, nasogastric tube and percutaneous endoscopic gastrostomy  are different methods of nutritional interventions, which have been compared due to their efficacy in maintaining the patients’ weight. In this study, we reviewed the results obtained in clinical trials about the efficacy of intense nutritional intervention on limiting the chemoradiotherapy-associated complications in patients with head and neck cancers.

    Neuromyelitis optica spectrum disorders (NMOSD) were generally thought to affect only central nervous system and spare peripheral aquaporin-4 (AQP4)-expressing organs. In recent years, however, increasing evidence has shown that skeletal muscle is involved in NMOSD. We provided a comprehensive review of the relevant literature and summarized the clinical and pathological characteristics of myopathy associated with NMOSD. NMOSD-associated myopathy seems to be characterized by mild muscle symptoms with prominent hyperCKemia and minimal changes on conventional pathological staining. Loss of AQP4 and deposition of IgG and activated complement products on sarcolemma of type II fibers are diagnostic features on immunohistochemical examinations. Creatine kinase leakage as a result of AQP4-IgG-induced, complement-mediated sarcolemmal injury may be a potential mechanism for hyperCKemia. Myopathy should be considered a component of NMOSD unified by AQP4-IgG seropositivity. PMID:26514543

    2010-01-01

    This is a report on the present state of the problem of determining the dimension of the Nichols algebra associated to a rack and a cocycle. This is relevant for the classification of finite-dimensional complex pointed Hopf algebras whose group of group-likes is non-abelian. We deal mainly with simple racks. We recall the notion of rack of type D, collect the known lists of simple racks of type D and include preliminary results for the open cases. This notion is important because the Nichols algebra associated to a rack of type D and any cocycle has infinite dimension. For those racks not of type D, the computation of the cohomology groups is needed. We discuss some techniques for this problem and compute explicitly the cohomology groups corresponding to some conjugacy classes in symmetric or alternating groups of low order.

    Microbial communities taking part in calcium carbonate lithification processes are particularly relevant to coral reef formation in as much as this lithification allows the stabilization of secondary reef structure. This second framework promotes long-term permanence of the reef, favoring the establishment of macro-reef builders, including corals. The reef-bacterial crusts formed by microbial communities are composed of magnesium calcite. Although prokaryotes are not proper calcifiers, carbonate precipitation can be induced by their metabolic activity and EPS production. Coral reefs are rapidly declining due to several variables associated to environmental change. Specifically in the Caribbean, stony coral Acropora palmata have suffered damage due to diseases, bleaching and storms. Some reports show that in highly disturbed areas wide ridges of reef rubbles are formed by biological and physical lithification. In this study we explore microbial diversity associated to lithified rubbles left after the great decline of reef-building A. palmata.

    Full Text Available CONTEXT: Acute pancreatitis during pregnancy is rare and commonly occurs in association with biliary disease. Preeclampsia is associated with microvascular abnormalities that may involve cerebral, placental, hepatic, renal and splanchnic circulation and rarely can cause acute pancreatitis. CASE REPORT: A case of acute pancreatitis in a patient with preeclampsia-eclampsia where the diagnosis was missed initially that resulted in a protracted course and development of organized pancreatic necrosis. The pancreatic necrosis resolved with conservative management over 8 weeks. CONCLUSIONS: The development of severe hypoalbuminemia, out of proportion to proteinuria, hypocalcemia and findings of capillary leak should alert the physician to search for other inflammatory causes, including acute pancreatitis so that early and effective management be given to avoid complications.

    Independent replication is vital for study findings drawn from Electronic Health Records (EHR). This replication study evaluates the relationship between seasonal effects at birth and lifetime cardiovascular condition risk. We performed a Season-wide Association Study on 1,169,599 patients from Mount Sinai Hospital (MSH) to compute phenome-wide associations between birth month and CVD. We then evaluated if seasonal patterns found at MSH matched those reported at Columbia University Medical Center. Coronary arteriosclerosis, essential hypertension, angina, and pre-infarction syndrome passed phenome-wide significance and their seasonal patterns matched those previously reported. Atrial fibrillation, cardiomyopathy, and chronic myocardial ischemia had consistent patterns but were not phenome-wide significant. We confirm that CVD risk peaks for those born in the late winter/early spring among the evaluated patient populations. The replication findings bolster evidence for a seasonal birth month effect in CVD. Further study is required to identify the environmental and developmental mechanisms. PMID:27624541

    Mineralization of bone and tooth extracellular matrix (ECM) is a physiologic process, while soft tissue mineralization, also known as ectopic mineralization (calcification), is a pathologic condition. Vascular calcification is common in aging and also in a number of genetic and metabolic disorders. The calcific deposits in arteries complicate the prognosis and increase the morbidity in diseases such as atherosclerosis, diabetes and chronic kidney disease (CKD). To completely understand the pathophysiology of these lifethreatening diseases, it is critical to elucidate the molecular mechanisms underlying vascular calcification. Unveiling these mechanisms will eventually identify new therapeutic targets and also improve the management of the associated complications. In the current review, we discussed the common determinants of ECM mineralization, the mechanism of vascular calcification associated with several human diseases and outlined the most common therapeutic approaches to prevent its progression.

    Two equations of state (PC-SAFT and CPA) are used to predict the monomer fraction of pure associating fluids. The models each require five pure-component parameters usually obtained by fitting to experimental liquid density and vapor pressure data. Here we also incorporate monomer fractions......-site schemes perform about equally for ethanol; for higher alcohols a two-site scheme is preferred. This is in accordance with steric arguments. Some difficulties in the interpretation of spectroscopic data and their comparison with the predictions of association models are illustrated. Apparently anomalous...... measured using spectroscopy, resulting in models that better predict the monomer fraction (fraction of molecules not participating in hydrogen bonding), without sacrificing the accuracy of the liquid density and vapor pressure correlations. Thus, it is clear that monomer fraction prediction depends on the...

    Control of spatiotemporal chaos in a neural network with discrete time and continuous state variables is investigated. The chaos control is performed with the knowledge of only a part of the target information in the memory patterns. The success rate for the pattern associations and the dependence of the search time on the sampling number in the proposed chaos neural network are studied. By the introduction of the reinforcement factor in the learning process, the recognition rate of the network can be much enhanced. Random and regular samplings of the pattern for the control are tested and the successful results of the associations are demonstrated. The chaotic behavior and recalling ability of the system are evaluated based on the analysis of the Lyapunov spectrum of the network.

    To describe a case of probable relapsing autoimmune hepatitis associated with vaccination against hepatitis A virus (HAV). A case report and review of literature were written concerning autoimmune hepatitis in association with hepatitis A and other hepatotropic viruses. Soon after the administration of formalin-inactivated hepatitis A vaccine, a man who had recently recovered from an uncharacterized but self-limiting hepatitic illness,experienced a severe deterioration (AST 1687 U/L, INR 1.4). Anti-nuclear antibodies were detectable, and liver biopsy was compatible with autoimmune hepatitis. The observation supports the role of HAV as a trigger of autoimmune hepatitis. Studies in helper T-cell activity and antibody expression against hepatic proteins in the context of hepatitis A infection are summarized, and the concept of molecular mimicry with regard to other forms of viral hepatitis and autoimmunity is briefly explored.

    Liberals conceive of territorial rights as dependent on the legitimacy of the state, which is in turn understood in terms of the state’s protection of individual rights and freedoms. Such justifications of territorial rights have difficulties in addressing the right to control immigration, which is...... therefore in need of additional justification. The paper considers Christopher Heath Wellman’s liberal proposal for justifying the right to control immigration, which understands the right as derivative of a general right to freedom of association held collectively by the people of the state. The paper...... argues that state legitimacy and freedom of political association fail to connect in the way required to justify a right to control immigration. Wellman’s argument conflates the state as an institution and the people as a political collective and elides the difference between territorial jurisdiction and...

    The recent progress of non-covalent associative structure of coal, and the mechanisms of the CS2/NMP (1:1 by volume) mixed solvent and the additive addition enhancing the extraction yield of coals were reviewed, and the aggregation behavior of coal in solid and solution states were presented, and the aggregation behavior of coal in solid and solution states were introduced in this paper. Coal extraction and swelling in organic solvents at room temperature were the most useful methods to understand the associative structure of coal. CS2/NMP (1:1 by volume) is a unique solvent to give high extraction yields for some bituminous coals. Some additives can dissociate the stronger interactions among coal molecules and enhance the extraction yields of coal in the mixed solvent.

    This paper focuses on a systematic treatment for developing a generic online learning control system based on the fundamental principle of reinforcement learning or more specifically neural dynamic programming. This online learning system improves its performance over time in two aspects: 1) it learns from its own mistakes through the reinforcement signal from the external environment and tries to reinforce its action to improve future performance; and 2) system states associated with the positive reinforcement is memorized through a network learning process where in the future, similar states will be more positively associated with a control action leading to a positive reinforcement. A successful candidate of online learning control design is introduced. Real-time learning algorithms is derived for individual components in the learning system. Some analytical insight is provided to give guidelines on the learning process took place in each module of the online learning control system. PMID:18244383

    A 42-year-old man with a history of childhood asthma presented with a 2-week history of watery diarrhoea and marked peripheral eosinophilia in the setting of recent use of cephalexin. His colonoscopy revealed patchy colitis. Biopsies were consistent with eosinophilic colitis. Two months later he received a course of amoxicillin resulting in recurrence of peripheral eosinophilia. Given the time-frame of β-lactam administration to symptom onset and elimination of all other precipitating causes, he was diagnosed with β-lactam-associated eosinophilic colitis. The patient's symptoms resolved and peripheral eosinophil count decreased with no specific treatment. Eosinophilic colitis is a rare heterogeneous condition, the pathogenesis of which is likely to be an interplay between environmental and genetic factors. It can be secondary to a helminthic infection or a drug reaction and has been associated with ulcerative colitis. If secondary causes of eosinophilic colitis have been excluded, the mainstay of treatment is with corticosteroids. PMID:26106168
