    Cutaneous eruptions and hypersensitivity represent frequently reported side effects of anti-seizure medications. However, these side-effects have rarely been previously reported for lacosamide, a newer-generation anti-seizure medication with a novel mechanism of action. Here, we report a case of diffuse skin eruption in a patient with history of epilepsy soon after initiation of lacosamide. The rash resolved after discontinuation of lacosamide and use of antihistamines and steroids. We also review the information on drug hypersensitivity syndrome.

    Full Text Available A patient of essential hypertension stabilized on 10 mg amlodipine once daily developed brownish black petechial non-blanching macular rash bilaterally covering the limbs below the knee and dorsum of the feet. History, general and clinical examinations and lab investigations revealed no abnormalities. Temporal association of the onset of rash with amlodipine use, inability to explain rash by natural history of hypertension, possibility of rash with amlodipine and rash resolution on dechallenge placed this reaction in Naranjo score of 6, a probable adverse reaction to amlodipine. Hence the drug was replaced by enalapril. The rash resolved completely over a period of eight weeks.

  10. Efficient Interaction Recognition through Positive Action Representation

    Directory of Open Access Journals (Sweden)

    Tao Hu

    2013-01-01

    Full Text Available This paper proposes a novel approach to decompose two-person interaction into a Positive Action and a Negative Action for more efficient behavior recognition. A Positive Action plays the decisive role in a two-person exchange. Thus, interaction recognition can be simplified to Positive Action-based recognition, focusing on an action representation of just one person. Recently, a new depth sensor has become widely available, the Microsoft Kinect camera, which provides RGB-D data with 3D spatial information for quantitative analysis. However, there are few publicly accessible test datasets using this camera, to assess two-person interaction recognition approaches. Therefore, we created a new dataset with six types of complex human interactions (i.e., named K3HI, including kicking, pointing, punching, pushing, exchanging an object, and shaking hands. Three types of features were extracted for each Positive Action: joint, plane, and velocity features. We used continuous Hidden Markov Models (HMMs to evaluate the Positive Action-based interaction recognition method and the traditional two-person interaction recognition approach with our test dataset. Experimental results showed that the proposed recognition technique is more accurate than the traditional method, shortens the sample training time, and therefore achieves comprehensive superiority.

    Objectives Two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) plus 1 non-NRTI (nNRTI) remain the preferred or alternative combination antiretroviral therapy (cART) for antiretroviral-naive HIV-positive patients in Taiwan. The three most commonly used nNRTIs are nevirapine (NVP), efavirenz (EFV) and rilpivirine (RPV). This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs. Methods Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study. According to the national HIV treatment guidelines, patients were assessed at baseline, 2 and 4 weeks of cART initiation, and subsequently every 8 to 12 weeks. Plasma HIV RNA load, CD4 cell count and aminotransferases were determined. The toxicity grading scale of the Division of AIDS (DAIDS) 2014 was used for reporting clinical and laboratory adverse events. Results During the 3.5-year study period, 2,341 patients initiated nNRTI-containing cART: NVP in 629 patients, EFV 1,363 patients, and RPV 349 patients. Rash of any grade occurred in 14.1% (n = 331) of the patients. In multiple logistic regression analysis, baseline CD4 cell counts (per 100-cell/μl increase, adjusted odds ratio [AOR], 1.125; 95% confidence interval [95% CI], 1.031–1.228) and use of NVP (AOR, 2.443; 95% CI, 1.816–3.286) (compared with efavirenz) were independently associated with the development of skin rashes. Among the 1,455 patients (62.2%) with aminotransferase data both at baseline and week 4, 72 (4.9%) developed grade 2 or greater hepatotoxicity. In multiple logistic regression analysis, presence of antibody for hepatitis C virus (HCV) (AOR, 2.865; 95% CI, 1.439–5.704) or hepatitis B surface antigen (AOR, 2.397; 95% CI, 1.150–4.997), and development of skin rashes (AOR, 2.811; 95% CI, 1

    A previously healthy Caucasian girl, 6 years of age, presented with pruritic rash on both heels of 6 months duration. The lesions appeared as multiple depressions 1-2 mm in diameter that progressively increased in size. There was no history of trauma or insect bite. She reported local pain when walking, worse with moisture and wearing sneakers. On examination, multiple small craterlike depressions were present, some coalescing into a larger lesion on both heels (Figure 1). There was an unpleasant 'cheesy' odour and a moist appearance. Wood lamp examination and potassium hydroxide testing for fungal hyphae were negative.

    Full Text Available Rashes can occur in any part of the body. But rash which appears on face has got both psychological and cosmetic effect on the patient. Rashes on face can sometimes be very challenging to physicians and dermatologists and those associated with oral manifestations pose a challenge to dentists. Butterfly rash is a red flat facial rash involving the malar region bilaterally and the bridge of the nose. The presence of a butterfly rash is generally a sign of lupus erythematosus (LE, but it can also include a plethora of conditions. The case presented here is of a female with butterfly rash along with typical bright red discoloration of gingiva. The clinical, histopathological and biochemical investigations suggested the presence of rosacea.

  18. Practical Management of Lenalidomide-Related Rash.

    Tinsley, Sara M; Kurtin, Sandra E; Ridgeway, Jean A

    2015-06-01

    Lenalidomide (LEN) is an immunomodulatory drug with US Food and Drug Administration approval for use in myelodysplastic syndromes (MDS), multiple myeloma (MM), and mantle cell lymphoma (MCL). The toxicity profile for LEN is similar across indications, with the most common adverse events reported in registration trials being hematologic in nature, and Grade ≥ 3 hematologic toxicities the most common reasons for treatment interruption or permanent LEN discontinuation. However, an analysis of the Celgene Global Drug Safety database showed that nonserious rash was the leading cause of permanent early discontinuation of LEN in patients with MDS treated in the postmarketing setting (similar data not available for patients with MM or MCL). In registration trials, rash was reported in up to a third of patients, but Grade ≥ 3 rash was uncommon and rash rarely led to LEN treatment interruption or permanent discontinuation. This suggests differences in management of LEN-related rash in clinical trials versus real-world use. Most LEN-related rash is mild to moderate in severity and might present as patchy, raised, macular skin lesions, sometimes with localized urticaria, which might be associated with pruritus. Mild to moderate rash might be treated with topical corticosteroids and/or oral antihistamines. Any grade LEN-related rash should be appropriately managed through awareness of symptoms, appropriate and prompt intervention, and maximizing patient self-reporting of early signs of rash using upfront educational initiatives. This guide to management of LEN-related rash reviews key clinical data from registration trials, and the incidence and physiology of LEN-related rash, grading of rash, and guidelines for patients and caregivers.

    Children with a petechial rash commonly present to emergency departments. The rash can be associated with serious illnesses, such as invasive meningococcal disease (IMD), but is usually associated with less severe conditions. This article discusses the common and important causes of petechial rash, including IMD, viral illnesses, trauma, Henoch-Schönlein purpura and idiopathic thrombocytopenic purpura. It also analyses the National Institute for Health and Care Excellence (NICE) ( 2014 ) pathway for management of petechial rash in children and examines treatment of the various causes. The article includes two relevant case studies and discusses the role of emergency nurses.

    2013-01-01

    To determine the safety of lamotrigine rechallenge after a first episode of skin rash in bipolar patients. An open cases prospective study was conducted with patients who, developed a skin rash when first treated with lamotrigine, were refractory to other treatments, and were offered lamotrigine rechallenge using a different dose titration. Additionally a review was performed on previous skin rash management strategies and lamotrigine rechallenge reports. Every 3 out of 10 lamotrigine rechallenge patients required drug interruption due to persistent rash. One of them was potentially serious and resolved by stopping the lamotrigine. The review of available literature identified several lamotrigine rechallenge studies with rates of positive results varying between 70% and 87% depending on the study. No patient developed Stevens-Johnson syndrome or toxic epidermal necrolysis after rechallenge. The rate of rash was higher when rechallenge began between 4 weeks from initial rash (19% vs. 7%, P=.001) and decreased when first rash showed no potentially serious signs (0% vs.19%, P=.01). Rechallenge is a viable option after a benign lamotrigine-induced rash, and can even be rechallenged after rash with greater precautions when there exists one or two potentially serious signs. In cases of more serious rash there are no reliable data available on rechallenge safety and it may pose a significant risk. In those cases rechallenge should better be avoided between 4 weeks from first rash. Copyright © 2011 SEP y SEPB. Published by Elsevier Espana. All rights reserved.

  3. Extensive VZV Encephalomyelitis without Rash in an Elderly Man

    2014-01-01

    Full Text Available Introduction. Varicella zoster virus (VZV encephalomyelitis with cranial nerve involvement is rare. Characteristically it is preceded by a rash and primarily presents in the immunocompromised. The spectrum of VZV neurologic disease is extensive and it is not uncommon to present without rash. We report the case of an elderly otherwise immunocompetent patient who presented with diverse manifestations of VZV CNS infection all occurring without rash. Case Report. A 78-year-old man presented with 1 week of progressive paraparesis and sensory loss, malaise, and fevers. MRI of the neuraxis demonstrated numerous enhancing lesions: intramedullary, leptomeningeal, pachymeningeal, and cranial nerves. Cerebrospinal fluid (CSF showed a white blood cell count of 420/μL with elevated protein (385 mg/dL. CSF VZV qualitative PCR was positive and CSF VZV immunofluorescence assay detected IgM antibody, confirming the diagnosis of VZV encephalomyelitis. Clinical and radiological improvement was observed after intravenous acyclovir treatment. Conclusion. This is a rare report of an immunocompetent patient with extensive VZV encephalomyelitis. We highlight the importance of considering this diagnosis even in the absence of the characteristic rash, and the potential risk of premature discontinuation of antiviral therapy once HSV has been excluded. Prompt recognition and treatment can dramatically reduce morbidity and mortality in patients.

  7. Skin rash during treatment with generic itraconazole

    Directory of Open Access Journals (Sweden)

    Antonio De Vuono

    2014-01-01

    Full Text Available Generic drugs have the same active substance, the same pharmaceutical form, the same therapeutic indications and a similar bioequivalence with the reference medicinal product (branded. Although a similar efficacy is postulated, some cases of clinical inefficacy during treatment with generic formulations have been reported. In this case, we describe a woman with onychomycosis that developed a skin rash during treatment with a generic formulation of itraconazole. Drug administration and its re-challenge confirmed the association between itraconazole and skin rash. Both Naranjo probability scale and World Health Organization causality assessment scale documented a probable association between generic-itraconazole and skin rash. The switch from generic formulation to brand one induced an improvement of symptoms. Since we are unable to evaluate the role of each excipient in the development of skin rash, we cannot rule out their involvement. However, more data are necessary to better define the similarities or differences between branded and generic formulations.

    2013-10-01

    Although the traditional bag-of-words model has shown promising results for human action recognition, in the feature coding phase, the ambiguous features from different body parts are still difficult to distinguish. Furthermore, it also suffers from serious representation error. We propose an innovative coding strategy called position and locality constrained soft coding (PLSC) to overcome these limitations. PLSC uses the feature position in a human oriented region of interest (ROI) to distinguish the ambiguous features. We first construct a subdictionary for each feature by selecting the bases from their spatial neighbor in human ROI. Then, a modified soft coding with locality constraint is adopted to alleviate the quantization error and preserve the manifold structure of features. This novel coding algorithm increases both the representation accuracy and discriminative power with low computational cost. The human action recognition experimental results on KTH, Weizmann, and UCF sports datasets show that PLSC can achieve a better performance than previous competing feature coding methods.

  10. Scientific Communication for Positive Action: Do's and Don'ts

    Science.gov (United States)

    Sanquini, A.; Wood, M. M.

    2015-12-01

    Natural hazard presentations often highlight disasters that may ensue from natural processes when mitigation or preparedness actions are not taken. Examples include images of raging fires, collapsed buildings, and flooded urban areas. Research has shown that this makes presentations more interesting and more memorable. Such images are the stock and trade of disaster reporting by the media. Unfortunately, it may also trigger avoidance and denial in the audience, resulting in preparedness reduction; the opposite effect of what may have been intended by the speaker. Recent social research has provided insight into a better approach. The theory of communicating actionable risk posits that people will take action against hazards when they know what to do, think it would work, and know someone who did it. This approach was recently applied in an intervention designed to motivate earthquake-resistant construction in Kathmandu Valley, Nepal. Social theory further suggests that a tendency towards action is strengthened by hearing a consistent message over time, and by providing the audience with an appropriate opportunity to seek out relevant information. This presentation shows how, by taking this transdisciplinary step, scientists can make small changes in their hazard communication, thereby acting as positive influencers of change. A summary of "do's" and "don'ts" is given for reference. 1. Show examples of what to do. 2. Show effectiveness of actions. 3. Give sense of knowing someone who did it. 4. Deliver consistent message, repeatedly. 5. Give opportunity for more information. DON'T: 1. Make the disaster the star. 2. Contradict other communications.

Growth curve analyses revealed evidence of favorable program effects on each of the four types of resources. The study contributes to PYD research by providing evidence for school-based interventions in low-income, urban contexts for ethnic minority youth.

  13. Methylenetetrahydrofolate reductase (MTHFR) deficiency presenting as a rash.

    LENUS (Irish Health Repository)

    Crushell, Ellen

    2012-09-01

    We report on the case of a 2-year-old girl recently diagnosed with Methylenetetrahydrofolate reductase (MTHFR) deficiency who originally presented in the neonatal period with a distinctive rash. At 11 weeks of age she developed seizures, she had acquired microcephaly and developmental delay. The rash deteriorated dramatically following commencement of phenobarbitone; both rash and seizures abated following empiric introduction of pyridoxine and folinic acid as treatment of possible vitamin responsive seizures. We postulate that phenobarbitone in combination with MTHFR deficiency may have caused her rash to deteriorate and subsequent folinic acid was helpful in treating the rash and preventing further acute neurological decline as commonly associated with this condition.

    Brucellosis is the most widespread zoonotic infection in the world. The disease is endemic in countries bordering the Mediterranean Sea. It is an important re-emerging infectious disease. This disease is closely associated with the evolution of mankind as an agrarian society linked to the practice of shepherding and popularization of animal husbandry. The patients with this disease are typically present with chills, fever, asthenia and sweating. This paper describes a patient with brucellosis and skin rashes on the leg. A 41-year-old man presented with fever, ataxia, and dysarthria. He was a shepherd. The patient reported the loss of appetite, arthralgia and weight loss during previous five months. Finally, he was diagnosed with brucellosis by positive blood culture and high titer for Brucella agglutination test. The clinical manifestation of brucellosis is very broad, ranging from asymptomatic infection to serious debilitating disease. Current patient had skin rashes on his leg. Brucellosis must be considered in the differential diagnosis of acute infections, especially if there is a history of fresh milk product ingestion and living in an endemic region.

The clinical manifestation of brucellosis is very broad, ranging from asymptomatic infection to serious debilitating disease. Current patient had skin rashes on his leg. Brucellosis must be considered in the differential diagnosis of acute infections, especially if there is a history of fresh milk product ingestion and living in an endemic region.

    Telaprevir-induced rash is a common, therapy-limiting adverse drug event (ADE) for patients with hepatitis c virus (HCV) infection. Given the similarity between telaprevir and simeprevir, real-world management of rash during treatment with an NS3/4A protease inhibitor and its implications are important. The objectives of this study were to determine the incidence of rash in telaprevir-treated patients, its management, and the impact on sustained virological response and to identify any risk factors for rash development. This was a retrospective study of adult patients who were treated with telaprevir in a hepatology clinic from July 1, 2011, to August 31, 2012. Pertinent information on demographics, past medical history, medications, laboratory data, outcomes of rash, other ADEs related to treatment, and physician grading of rash were collected. Of 159 patients included, 44% (70/159) developed rash, and 4% (7/159) discontinued therapy because of rash. Median number of days until rash did not differ between patients who continued and discontinued therapy (25 vs 45, respectively; P = 0.88). Patients who developed rash were more likely to have lower actual body weight (ABW) or body mass index (BMI; P ≤ 0.01). No significant difference in rash development when drug-allergy history was considered was found. Most patients who continued telaprevir were prescribed topical corticosteroids (93.7%) and cetirizine (41.3%). Patients who discontinued therapy were more likely to be evaluated by dermatology (P = 0.002), prescribed oral corticosteroids (P = 0.02), hydroxyzine (P = 0.001), and topical triamcinolone (P = 0.01). ABW and BMI appear to be related to rash development. This finding may have implications in the treatment of HCV with simeprevir, given its similarity to telaprevir. © The Author(s) 2014.

    Skin rashes are commonly seen by the primary care physician. The chief cause of contact dermatitis is the plant genus Toxicodendron, but topical medications such as anesthetics, antibiotics, and preservatives also cause this condition. Commonly seen superficial fungal infections include candidiasis and several types of tinea. Microscopic identification of the organism on a potassium hydroxide (KOH) preparation establishes the definitive diagnosis. In addition to occurring in its usual sites, the herpes simplex virus can cause recurrent disease on glabrous skin areas. A positive Tzanck test establishes a diagnosis of herpesvirus infection. Mosquito, flea, and brown recluse spider bites produce diagnostic physical findings. Scabies infestation produces a distinctive eruption, and the diagnosis is made by isolating the mite or its products.

    Full Text Available Authenticity can best be understood in context, and context implies action (Payne, 1996. For the purpose of this study, leadership in general, and authentic leadership in particular, were explored in terms of the actions of former mayor of New York City, Rudolph Giuliani, who displayed authentic leadership in action during the tragic aftermath of the World Trade Centre attacks. Authentic leadership development tends to be triggered by a negative event (as in the case of 9/11 for Giuliani, for example. Since there is limited knowledge of how a positive event may trigger authentic leadership development, the aim of this study was to explore the potential of Appreciative Inquiry (AI - an affirmative mode of action research - as a positive trigger event for authentic leadership development. The results indicated that this positive approach to change could indeed be implemented for this purpose.

    Skin in the diapered area is continuously threatened by exposure to changes in pH levels, overhydration, mechanical friction, and fecal enzymes, making diaper rash a common occurrence among babies. Up to one third of infants may exhibit clinical symptoms of diaper rash at any time, and more than half of babies between the ages of 4 and 15 months develop diaper rash at least once in a 2-month period. Despite misperceptions that disposable diapers are related to an increase in diaper rash, the incidence of diaper dermatitis is on the decline, largely due to significant improvements in disposable diaper construction and materials. Modern-day disposable diapers are specifically designed to limit exposure to irritants in the diaper area, reduce overhydration, inhibit skin barrier compromise, and help maintain normal skin pH levels and have been thoroughly evaluated for safety and skin compatibility.

    Icodextrin may be used as an alternative to glucose as the osmotic agent in peritoneal dialysis with ultrafiltration failure. In general, icodextrin is known to be safe and well tolerated, but it can also cause hypersensitivity reactions such as skin rashes. Allergic rashes are generally defined as erythematous, itchy and maculopapular, visible over the trunk and the extremities. When a rash occurs, it generally develops early in therapy, is self-limited, and resolves without sequelae after the discontinuation of icodextrin. Although the safety and efficacy of icodextrin peritoneal dialysis solution is well documented, clinicians should be aware of the possibility of severe adverse cutaneous reactions to it. We report the case of a 23-year-old female who developed a skin rash following the use of icodextrin.

  3. Dopaminergic modulation of positive expectations for goal-directed action: evidence from Parkinson’s disease

    Full Text Available Parkinson’s disease (PD impairs the control of movement and cognition, including the planning of action and its consequences. This provides the opportunity to study the dopaminergic influences on the perception and awareness of action. Here we examined the perception of the outcome of a goal-directed action made by medicated patients with PD. A visuomotor task probed the integration of sensorimotor signals with the positive expectations of outcomes (Self priors, which in healthy adults bias perception towards success in proportion to trait optimism. We tested the hypotheses that (i the priors on the perception of the consequences of one’s own actions differ between patients and age- and sex-matched controls, and (ii that these priors are modulated by the levodopa dose equivalent in patients. There was no overall difference between patients and controls in the perceptual priors used. However, the precision of patient priors was inversely related to their levodopa dose equivalent. Patients with high levodopa dose equivalent showed more accurate priors, representing predictions that were closer to the true distribution of performance. Such accuracy has previously been demonstrated when observing the actions of others, suggesting abnormal awareness of action in these patients. These results confirm a link between dopamine and the positive expectation of the outcome of one’s own actions, and may have implications for the management of PD.

In clinical trials, rash was common, although severe rash was infrequent. To examine rash in patients with MDS treated with lenalidomide in the real world, the Celgene Global Drug Safety database was analyzed and compared with clinical trials.Materials and methods: Adverse event reports in the post-marketing setting and in the MDS-003/004 clinical trials were analyzed by action taken with lenalidomide, seriousness/grade, time to onset, and treatment duration.Results: Globally, 16,942 reports representing 36,793 adverse events from the post-marketing setting were submitted to the Global Drug Safety database between December 27, 2005 and June 13, 2013. Most rash adverse events were non-serious (Global Drug Safety database, 91% or grade 1/2 (MDS-003/004 trials, 87%–93%. Unexpectedly, rash, occurring at a median of 9 days after treatment initiation, was the leading cause of permanent discontinuation of lenalidomide. Seventy-two percent of non-serious rash adverse events led to early permanent discontinuation within two cycles, while in the MDS-003/004 pivotal clinical trials, only 2%–3% of rash adverse events led to permanent discontinuation.Conclusion: Non-serious rash was the most common reason for permanent discontinuation of lenalidomide in real-world settings. Managing lenalidomide-related rash using published recommendations might improve treatment duration and optimize patient outcomes. Keywords: adverse events, safety, post-marketing setting 

  5. A Case Report of Rash at Peritoneal Dialysis Exit Site

    Directory of Open Access Journals (Sweden)

    Elvira O. Gosmanova MD, FASN

    2015-11-01

    Full Text Available The International Society for Peritoneal Dialysis recommends the regular application of topical antibiotic-containing preparations in addition to a routine exit site care to reduce the risk of exit site infection (ESI. Among these prophylactic antimicrobial preparations, topical gentamicin is one of the widely used and effective antibiotics for prevention of ESI and peritonitis in peritoneal dialysis (PD patients. Overall, topical gentamicin is well tolerated; however, its use can be associated with the development of allergic contact dermatitis (ACD. We describe a first reported case of PD catheter exit site contact ACD due to topical gentamicin mimicking ESI. The patient in this report developed worsening violaceous in color and pruritic rash surrounding the PD catheter exit site that appeared 3 weeks after the initiation of gentamicin cream. The association between development of rash and initiation of topical gentamicin led to a suspicion of local reaction to gentamicin rather than ESI. Skin biopsy confirmed ACD. Discontinuation of the provoking agent and subsequent treatment with topical hydrocortisone application led to a resolution of the exit site rash. Any rash at a PD catheter exit site should be considered infectious until proven otherwise. However, it is important to be aware of noninfectious etiologies of exit site rashes as the treatment of these 2 conditions differs.

    A 49-year old woman noticed her skin rash several days after taking supplements containing Spirulina, a planktonic blue-green alga. Her skin rash was spreading over large parts of her body, even after stop ingestion two months later. Five months later, she developed muscle weakness of neck flexor and left proximal upper extremity. On admission, creatine kinase (CK) was elevated to 1,268 IU/ml in the serum. A muscle specimen revealed many necrotizing muscle fibers and the infiltration of mononuclear cells in the peri- and endomysium including a lot of eosinophils. Immunohistochemical staining showed the infiltration of CD4 positive cells in the peri- and endomysium and that of CD20 positive B cells in the perivascular regions. She was diagnosed as having inflammatory myopathy with widely skin rash. Therapy with administration of prednisolone and cyclophosphamide followed by methyl-prednisolone pulse improved her clinical symptoms. There is a similar report describing a case of dermatomyositis after ingestion of Spirulina, which is known to have immune-stimulating property such as accelerating tumor necrosis factor (TNF)-alpha production. Also, TNF-alpha single nucleotide polymorphisms (TNF-308A) was demonstrated to have strong association with onset of myositis in Caucasians. The use of Spirulina could result in inflammatory myopathy under some specific conditions.

    Erlotinib is an epidermal growth factor receptor inhibitor prescribed to patients with locally advanced or metastasized non-small cell lung carcinoma after failure of at least one earlier chemotherapy treatment. Approximately 75% of the patients treated with erlotinib develop acneiform skin rashes. A patient treated with erlotinib 3 months after finishing concomitant treatment with chemotherapy and radiotherapy for non-small cell lung cancer is presented. Unexpectedly, the part of the skin that had been included in his previously radiotherapy field was completely spared from the erlotinib-induced acneiform skin rash. The exact mechanism of erlotinib-induced rash sparing in previously irradiated skin is unclear. The underlying mechanism of this phenomenon needs to be explored further, because the number of patients being treated with a combination of both therapeutic modalities is increasing. The therapeutic effect of erlotinib in the area of the previously irradiated lesion should be assessed. (orig.)

    The present study examined action planning and position sense in children with Developmental Coordination Disorder (DCD). Participants performed two action planning tasks, the sword task and the bar grasping task, and an active elbow matching task to examine position sense. Thirty children were included in the DCD group (aged 6-10years) and age-matched to 90 controls. The DCD group had a MABC-2 total score ⩽5th percentile, the control group a total score ⩾25th percentile. Results from the sword-task showed that children with DCD planned less for end-state comfort. On the bar grasping task no significant differences in planning for end-state comfort between the DCD and control group were found. There was also no significant difference in the position sense error between the groups. The present study shows that children with DCD plan less for end-state comfort, but that this result is task-dependent and becomes apparent when more precision is needed at the end of the task. In that respect, the sword-task appeared to be a more sensitive task to assess action planning abilities, than the bar grasping task. The action planning deficit in children with DCD cannot be explained by an impaired position sense during active movements.

    Full Text Available Isotretinoin is a vitamin A analogue, which is readily isomerized to tretinoin. It causes normalization of abnormal keratinisation. It also reduces sebum secretion. It also has anti-inflammatory as well as antibacterial properties. It has some adverse effects like teratogenecity, hypertriglyceridemia, pancreatitis, dryness of skin, cheilitis, altered liver functions etc. A 25 years old unmarried lady presented with acne vulgaris, who did not showed improvements with conventional (antibiotics therapy was given isotretinoin. She developed maculopapular rash, urticaria and angioedema Isotretinoin induced urticarial rashes and angioedema is rarely reported as far as our knowledge is concerned.

    Certain Gram-positive bacteria, including meticillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and quinolone-resistant Streptococcus pneumoniae have achieved the status of "superbugs", in that there are few or no antibiotics available for therapy against these pathogens. Only a few classes of novel antibiotics have been introduced in the past 40 years, and all since 1999, including the streptogramin combination quinupristin/dalfopristin (Synercid), the oxazolidinone linezolid, and the lipopeptide daptomycin. This review discusses the mechanisms of antibiotic action against Gram-positive pathogens, and resistance counter-mechanisms developed by Gram-positive bacteria, with emphasis on the newer agents.

    Full Text Available Human parvovirus B19 infection can cause erythema infectiosum (EI and several other clinical presentations. Central nervous system (CNS involvement is rare, and only a few reports of encephalitis and aseptic meningitis have been published. Here, we describe 2 cases of B19 infection in a family presenting different clinical features. A 30 year old female with a 7-day history of headache, malaise, myalgias, joint pains, and rash was seen. Physical examination revealed a maculopapular rash on the patient's body, and arthritis of the hands. She completely recovered in 1 week. Two days before, her 6 year old son had been admitted to a clinic with a 1-day history of fever, headache, abdominal pain and vomiting. On admission, he was alert, and physical examination revealed neck stiffness, Kerning and Brudzinski signs, and a petechial rash on his trunk and extremities. Cerebrospinal fluid analysis was normal. He completely recovered in 5 days. Acute and convalescent sera of both patients were positive for specific IgM antibody to B19. Human parvovirus B19 should be considered in the differential diagnosis of aseptic meningitis, particularly during outbreaks of erythema infectiosum. The disease may mimic meningococcemia and bacterial meningitis.

    Background We aimed to investigate the efficacy and safety of botulinum toxin (BT) injections for jerky action tremor of the upper limb. Methods We performed an uncontrolled, prospective study of electromyography (EMG)-guided BT injections for jerky, position-specific, upper limb action tremor. The primary outcome was clinical global impression at 3–6 weeks after baseline. Results Eight patients with jerky, position-specific action tremor involving the upper limb were consecutively recruited. After a median follow-up of 4.4 weeks (interquartile range [IQR] 3.6–6 weeks), four of them rated themselves as “improved” and two as “much improved.” Five of these six subjects reported improvements in specific activities of daily living (bringing liquids to mouth, feeding, shaving, and dressing). Upper limb subscore of the Fahn–Tolosa–Marin Tremor Rating Scale (FTM) significantly decreased from 4.5 (4–6) to 3 (2–5) (p = 0.01). Discussion This pilot, prospective cohort study suggests that EMG-guided BT injections may improve jerky, position-specific, upper limb action tremor. Placebo-controlled studies evaluating larger samples of patients are warranted to confirm these findings. PMID:27818844

  19. Increasing Gender Diversity in Senior Roles in HE: Who Is Afraid of Positive Action?

    Directory of Open Access Journals (Sweden)

    Simonetta Manfredi

    2017-06-01

    Full Text Available This article argues that Higher Education Institutions should adopt positive action in recruitment and promotion to tackle women’s under-representation in senior leadership roles. In a tie-break situation where two candidates are “as qualified as each other”, section 159 of the UK Equality Act 2010 allows employers to give preference to a candidate from an under-represented group. The use of this measure, however, is often contested on the grounds that it is a form of reverse discrimination, it is tokenistic and that it can undermine meritocracy. This article seeks to challenge these objections and suggests that, far from undermining meritocracy, the use of positive action in recruitment and promotion could prove a useful tool to tackle gender bias, unpack stereotypes and re-appraise how merit is defined and assessed.

    Previous research has shown that (a) positive intergroup contact with an advantaged group can discourage collective action among disadvantaged-group members and (b) positive intergroup contact can encourage advantaged-group members to take action on behalf of disadvantaged outgroups. Two studies investigated the effects of negative as well as positive intergroup contact. Study 1 ( n = 482) found that negative but not positive contact with heterosexual people was associated with sexual-minority students' engagement in collective action (via group identification and perceived discrimination). Among heterosexual students, positive and negative contacts were associated with, respectively, more and less LGB (lesbian, gay, bisexual) activism. Study 2 ( N = 1,469) found that only negative contact (via perceived discrimination) predicted LGBT (lesbian, gay, bisexual, and transgender) students' collective action intentions longitudinally while only positive contact predicted heterosexual/cisgender students' LGBT activism. Implications for the relationship between intergroup contact, collective action, and social change are discussed.

    Positioning along the joint during the electron beam welding is a difficult scientific and technical problem to achieve the high quality of welds. The final solution of this problem is not found. This is caused by weak interference protection of sensors of the joint position directly in the welding process. Frequently during the electron beam welding magnetic fields deflect the electron beam from the optical axis of the electron beam gun. The collimated X-ray sensor is used to monitor the beam deflection caused by the action of magnetic fields. Signal of X-ray sensor is processed by the method of synchronous detection. Analysis of spectral characteristics of the X-ray sensor showed that the displacement of the joint from the optical axis of the gun affects on the output signal of sensor. The authors propose dual-circuit system for automatic positioning of the electron beam on the joint during the electron beam welding in conditions of action of magnetic interference. This system includes a contour of joint tracking and contour of compensation of magnetic fields. The proposed system is stable. Calculation of dynamic error of system showed that error of positioning does not exceed permissible deviation of the electron beam from the joint plane.

    Few case reports have been published on disseminated gonococcal infection in Japan. We report such a non-HIV case without typical skin rash. A 49-year-old Japanese man living in Thailand on business was seen for fever and multiple arthralgia after returning to Japan. Given the travel history, differential diagnoses included endemic viral infection such as human immunodeficiency virus (HIV), dengue fever, and chikungunya. Diagnosis was based on right-knee arthrocentesis, and synovial fluid culture followed by Neisseria gonorrhoeae polymerase chain reaction (PCR). The isolated strain was sensitive to penicillin. The man was treated with intravenous ceftriaxone and oral levofloxacin. Disseminated gonococcal infection should thus be considered when examining those with classical polyarthralgia symptoms even without a typical skin rash.

    Flosequinan is an arterial and venous dilator that also has a positive inotropic effect at relatively higher doses. The purpose of this study was to determine the mechanism of this positive inotropic effect in ferret papillary muscles loaded with the Ca2+ indicator, aequorin. Over the range of doses from 10(-6) to 10(-3) M, flosequinan produced a 61 +/- 9% increase in peak tension that was accompanied by a corresponding increase in [Ca2+]i. This positive inotropic effect was not selectively blocked by addition to the perfusate of procaine 0.6 microM, tetrodotoxin 10(-6) M or by verapamil, 5 x 10(-8) M. In contrast, the positive inotropic effect of flosequinan, but not milrinone or hydralazine, was potentiated by prior addition of ouabain 3 nM to enhance intracellular Ca2+ via reduction of the Na+/Ca2+ exchange. Moreover, antagonists of Na+/Ca2+ exchange, including cadmium 10 microM, amiloride 600 microM and choline substitution for 1/3 Na+ in the perfusate, blocked the response to flosequinan but not hydralazine or milrinone. These results indicate that flosequinan produces a positive inotropic effect by reduction of Na+/Ca2+ exchange in mammalian myocardium. Moreover, flosequinan has the potential to interact synergistically with other positive inotropic agents such as digoxin that affect Na+/Ca2+ exchange by direct or indirect actions.

    The association of fever with illness has been known for years. A febrile child may have rash, and physicians need to know when this symptom combination is a benign versus a pathologic clinical presentation. In other terms, potential etiologies are either infectious or non-infectious. With scrupulous, methodical history taking and careful, serial physical examination, the treating physician will find hints to assess and solidify an appropriate diagnosis, and chose an appropriate treatment.

    To provide an extensive review of case reports, epidemiological data, and the underlying mechanism of antibiotic-induced skin rash in patients with concurrent infectious mononucleosis (IM). A MEDLINE literature search inclusive of the dates 1946 to June 2016 was performed using the search terms anti-bacterial agents and infectious mononucleosis. EMBASE (1980 to June 2016) was searched using the terms mononucleosis and antibiotic agent and drug eruption. References of all relevant articles were reviewed for additional citations and information. We selected English-language, primary literature, review articles, and mechanistic articles that addressed antibiotic-induced skin rash in patients with concurrent IM. We assessed all case reports available for causality utilizing a modified Naranjo nomogram specifically designed for this subject. We assembled the available epidemiological data into tables to identify trends in incidence rates over the years. We identified 17 case reports of antibiotic-associated rash in patients with IM. The median Naranjo score was 6 (range = 1 to 8). The top 3 reported drugs were ampicillin, azithromycin, and amoxicillin. Incidence of this adverse effect was higher in the 1960s (55.6%, 45%, and 33%) than in 2013 (33% and 15%). The mechanism most commonly proposed is a transient virus-mediated immune alteration that sets the stage for loss of antigenic tolerance and the development of a reversible, delayed-type hypersensitivity reaction to the antibiotic. A reassessment of the long-held belief of the high incidence (80%-100%) of antibiotic-induced skin rash in patients with IM seems prudent. Additional studies will be necessary to clarify this issue.

    A 9-week in vivo rasH2/butylhydroxytoluene (BHT) model for the detection of genotoxic lung carcinogens was validated, using six potent positive test compounds, dimethylnitrosamine (DMN; 15 mg/kg, i.p.), diethylnitrosamine (DEN; 100 mg/kg, i.p.), ethylnitrosourea (ENU; 120 mg/kg, i.p.), 3-methylcholanthrene (MC; 100 mg/kg, i.p.), 7,12-dimethylbenz(a)anthracene (DMBA; 5 mg/kg, i.g.) and benzo(a)pyrene (B(a)P; 80 mg/kg, i.p.), each given to rasH2 mice of both genders by single administration for initiation followed by promoter BHT treatment. Statistically significant increase in the incidence and multiplicity of lung tumors was observed in rasH2 mice treated with BHT following exposure to all of the carcinogens tested. The data overall suggest the rasH2/BHT model to be a powerful screening tool for genotoxic lung carcinogens.

    Full Text Available Objective: To evaluate the validity of vaginal discharges, urethral discharges, genital rashes, and painful genital ulcers as indicators of early detection of incident herpes simplex virus type 2 (HSV-2 infection among pregnant women in Benin metropolis. Methods: Participants were antenatal clinic attendees of University of Benin Teaching Hospital and Central Hospital, Benin. Baseline sociodemographic, obstetric and HSV-2 serological data were collected. The HSV-2-seronegative returned for a repeat HSV-2 antibody assay before delivery date. Data on incidence of genital rashes, abnormal vaginal discharges, painful genital ulcers and urethral discharges were collected. Results: The sensitivities of abnormal vaginal discharges, genital rashes, urethral discharges and painful genital ulcers were 82.3%, 70.6%, 41.2% and 28.6% respectively; while their positive-predictive values were 53.8%, 60.0%, 58.3% and 66.7% respective. All the symptoms had >95% specificities and 95% negative-predictive values for seroincident HSV-2 infection. Conclusions: Abnormal vaginal discharge, genital rashes, urethral discharges and genital ulcers are valid indicators of seroincident HSV-2 infection and could be useful in formulation of screening tools in resource-limited settings.

    In rugby union, published analyses of actions and movements of players during matches have been limited to small samples of games at regional or national level. To analyse movements and activities of players in international rugby union matches with a sample size sufficient to clearly delineate positional roles. Observational study. Actions of 763 players were coded from video recordings of 90 international matches played by the New Zealand national team (the All Blacks) from 2004 to 2010. Movements of players were coded for 27 of these matches via a semi-automated player-tracking system. Movements and activities of all players from both teams were coded. Cluster analysis of activities and time-motion variables produced five subgroups of forwards (props, hookers, locks, flankers, Number 8 forwards) and five subgroups of backs (scrum-half, fly-half, midfield backs, wings and fullbacks). Forwards sustained much higher contact loads per match than backs, via scrums, rucks, tackles and mauls. Mean distance covered per match ranged from 5400 to 6300m, with backs generally running further than forwards. There were marked differences between positional groups in the amount of distance covered at various speeds. The amount of play per match varies by position due to differences in rates at which players are substituted. The distance covered by players at relatively fast running speeds (in excess of 5ms(-1)) appears to be higher during international matches than when competing at lower levels of the professional game. The specific match demands for positional groups need to be considered when managing player workloads. Copyright © 2012 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

    2011-01-01

    A case of cutaneous Rosai-Dorfman disease (CRDD) presenting as a granulomatous rosacea-like rashs was reported. A 45-year-old Chinese woman presented with a 1-month history of a widespread nonpruiginous papulonodular eruption.The rash had begun on her face and rapidly progressed to involve the neck and extremities. She was otherwise healthy,with no history of fever, malaise, or weight loss. Physical examination revealed multiple symmetrically distributed discrete and coalescing red plaques, papules and nodules scattered over the face, neck and extremities. No appreciable lymphadenopathy or hepatosplenomegaly was noted. There was no mucosal involvement. The biopsy specimen obtained from the face demonstrated the epidermis was normal, while the superficial dermis contained sheets of histiocytes with abundant, focally foamy cytoplasm. The histiocytes were surrounded by a patchy lymphocytic and plasma cell infiltrate. There was no significant histiocytic atypia. Some of these histiocytes engulfed, without destroying,lymphocytes and neutrophils (emperipolesis). Immunohistochemical staining revealed that the histiocytes were strongly positive for S100 protein, weakly positive for CD68, and negative for CD1a. A diagnosis of CRDD was made. Oral prednisone therapy was initiated at a dosage of 30 mg/d for 3 weeks and then tapered over the ensuing 2 weeks. After 5weeks of treatment, the lesions had markedly improved.

    Full Text Available Drug rash with eosinophilia and systemic symptoms (DRESS syndrome is an adverse reaction commonly occurring with antiepileptic agents. It was earlier referred to by various names such as dilantin hypersensitivity syndrome and anticonvulsant hypersensitivity syndrome. It is characterized by the triad of fever, skin eruption, and systemic involvement. DRESS syndrome has also been reported with a number of other drugs including allopurinol, minocycline, terbinafine, sulfonamides, azathioprine, dapsone, and antiretroviral agents such as abacavir and nevirapine. We describe a rare case of nevirapine-induced hypersensitivity syndrome that was successfully treated with oral steroids.

    A 14-year-old boy of Arabic origin presented with a pellagra-like rash and neurological manifestations including ataxia, dysarthria, nystagmus, and coma. There was a striking response to oral nicotinamide. The laboratory findings were not typical of Hartnup disease: aminoaciduris and indicanuria were absent and there was no evidence of tryptophan malabsorption. Tryptophan loading did not induce tryptophanuria nor did it increase excretion of xanthurenic or kynurenic acids. These findings support the possibility of a block in tryptophan degradation. The family history suggests a genetically-determined disorder. PMID:6451201

    In previous work from our laboratory, animals running for intravenous cocaine developed a unique approach-avoidance 'retreat behavior' that was hypothesized to result from cocaine's well documented reinforcing (positive) and anxiogenic (negative) properties. To assess the role of central mechanisms in producing cocaine's positive and negative effects, we assessed whether or not animals running a straight alley for intracerebroventricular applications of cocaine would produce a similar behavioral profile to that previously observed with intravenous applications. Retreat frequency and location were measured in male Sprague-Dawley rats trained to run an alley for one of four doses of intracerebroventricular-administered cocaine (0, 25, 50 or 100 microg cocaine/infusion). Testing involved a single trial per day over 14 consecutive days with a single infusion of cocaine delivered upon goal box entry. The 100 and 50 microg intracerebroventricular cocaine groups exhibited significantly higher retreat frequencies than the 25 and 0 microg groups and the nature and magnitude of the behavior was comparable to that previously observed with intravenous cocaine. These results suggest that the intracerebroventricular self-administration of cocaine results in mixed positive and negative consequences and therefore likely stem from the drug's actions within the central nervous system.

    Cutaneous reactions secondary to medications are rare but can be serious events resulting in morbidity and mortality and can be caused by anticonvulsant medications. Levetiracetam has been considered relatively safe compared with other antiepileptics with regard to skin eruptions. We report a case of a cutaneous reaction secondary to levetiracetam. A 64-year-old man presented to the hospital with an altered mental status and aphasia. Imaging revealed a left basal ganglia mass. A biopsy of the lesion was obtained, and levetiracetam was started at 500 mg intravenously twice a day for seizure prophylaxis. After 13 doses, the patient developed a diffuse, erythematous, warm, blanching, morbilliform rash. Levetiracetam was discontinued, and methylprednisolone was started. After 4 days, the rash dissipated. Levetiracetam is an antiepileptic medication that has an unknown mechanism of action. To date, there are only 4 cases reported involving skin reactions from levetiracetam. Two of the cases were classified as Stevens-Johnson Syndrome: 1 as toxic epidermal necrolysis and 1 as erythema multiforme. Our case was classified as a morbilliform rash. A Naranjo score of 7 suggested a probable cause for a levetiracetam-induced skin reaction. Antiepileptic medications are used in certain cases to prevent seizures in patients with central nervous system tumors. Although levetiracetam seems to have fewer side effects than the traditional antiepileptic medications, it is important for the healthcare provider to continuously evaluate the need for all medications and discontinue unneeded ones to help avoid potential medication adverse effects.

    Full Text Available Despite the importance of adolescent depression, few school-based prevention programs have been developed and tested in the United States with middle school populations. This study examined the acceptability and changes in targeted outcomes for a new preventative program, Positive Thoughts and Actions (PTA. Sixty-seven 7th grade students with elevated depressive symptoms were recruited from public schools and randomized to the 12-week PTA program with a parent-component or to a school-as-usual control group. The PTA prevention program was well received by students and parents, yielding high rates of participation and satisfaction among those randomized to receive the intervention. However, analyses of the efficacy of the program in changing depressive symptoms were not significant. In terms of our proximal program targets, most differences were not statistically significant, though effect sizes suggested advantage of PTA over control group in coping, cognitive style, and parent-child communication. This preliminary research highlights a need for further testing of programs for school-based prevention of depression and promotion of positive emotional health.

    A prolonged use of topical corticosteroids can result in Cushing syndrome, though this is less common than with oral or parenteral steroids. Most pediatric cases were due to application of topical steroids for diaper dermatitis. Adverse cardiovascular effects can occur in Cushing syndrome with significant long-term morbidity and mortality, though so far there have been no reports of cardiovascular complications due to excessive usage of topical steroids. We report a 2.5-month-old boy who rapidly developed severe Cushing syndrome induced by the misuse of topical clobetasol, a very potent steroid, without a doctor's prescription as a diaper rash cream, and developed moderate left ventricular hypertrophy and pericardial effusion. © 2014 S.

    A positive semi-definite Euclidean action for arbitrary four-topologies can be constructed by adding appropriate Yang-Mills and topological terms to the Samuel-Jacobson-Smolin action of gravity with (anti)self-dual variables. Moreover, the (anti)self-dual sector of the new theory corresponds precisely to {\\it all} Einstein manifolds in four dimensions. The Lorentzian signature action, and its analytic continuations are also considered. A self-contained discussion is given on the effects of discrete transformations C, P and T on the Samuel-Jacobson-Smolin action and other proposed actions which utilize self- or anti-self-dual variables as fundamental variables in the description of four-dimensional gravity.

    This study was conducted to compare the outcomes of a group-based cognitive-behavioral preventive intervention (Positive Thoughts and Actions [PTA]) tailored to youth in middle school with a brief, individually administered supportive intervention (Individual Support Program [ISP]). A randomized, controlled trial was conducted with 120 early adolescents (72 girls, 48 boys; age = 11-15 years) who had elevated depressive symptoms and were selected from a school-based population. Measures of internalizing problems, externalizing problems, personal adjustment, school problems, and interpersonal relations were obtained from parents, youth, and/or teachers at preintervention (Time 1) and postintervention (Time 2, 5-7 months after preintervention). General linear model repeated measures analyses yielded a significant Group × Time interaction on youth-reported, but not parent-reported, depressive symptoms and internalizing symptoms. Youth in the PTA group showed greater decreases following intervention compared to youth who received ISP, yielding effect sizes (Cohen's d) of 0.36 for depressive symptoms, 95% CI [-.02, .73], and 0.44, 95% CI [.05, .82], for internalizing symptoms. PTA youth also showed improvements in their personal adjustment (sense of inadequacy, self-esteem), and parent-reported social skills, but no differences emerged between groups for externalizing symptoms, school problems, or interpersonal relationships. Cognitive-behavioral preventive interventions in which youth engage in personal goal-setting and practice social-emotional skills, such as PTA, may be beneficial for the reduction of depressive symptoms over and above general support and empathy.

    The temporal relationship between our conscious intentions to act and the action itself has been widely investigated. Previous research consistently shows that the motor intention enters awareness a few 100 ms before movement onset. As research in other domains has shown that most behavior is affected by the emotional state people are in, it is remarkable that the role of emotional states on intention awareness has never been investigated. Here we tested the hypothesis that positive and negative affects have opposite effects on the temporal relationship between the conscious intention to act and the action itself. A mood induction procedure that combined guided imagery and music listening was employed to induce positive, negative, or neutral affective states. After each mood induction session, participants were asked to execute voluntary self-paced movements and to report when they formed the intention to act. Exposure to pleasant material, as compared to exposure to unpleasant material, enhanced positive affect and dampened negative affect. Importantly, in the positive affect condition participants reported their intention to act earlier in time with respect to action onset, as compared to when they were in the negative or in the neutral affect conditions. Conversely the reported time of the intention to act when participants experienced negative affect did not differ significantly from the neutral condition. These findings suggest that the temporal relationship between the conscious intention to act and the action itself is malleable to changes in affective states and may indicate that positive affect enhances intentional awareness.

    2017-10-01

    A 32-year-old man was admitted to our hospital with fever, chills, malaise, leukopenia, and a rash. About 3 weeks earlier, he'd had oral maxillofacial surgery and started a 10-day course of prophylactic amoxicillin/clavulanic acid. Fifteen days after the surgery, he developed a fever (temperature, 103° F), chills, arthralgia, myalgia, cough, diarrhea, and malaise. He was seen by his physician, who obtained a chest x-ray showing a lingular infiltrate. The physician diagnosed influenza and pneumonia in this patient, and prescribed oseltamivir, azithromycin, and an additional course of amoxicillin/clavulanic acid. Upon admission to the hospital, laboratory tests revealed a white blood cell count (WBC) of 3.1 k/mcL (normal: 3.2-10.8 k/mcL). The patient's physical examination was notable for lip edema, white mucous membrane plaques, submandibular and inguinal lymphadenopathy, and a morbilliform rash across his chest. Broad-spectrum antibiotics were initiated for presumed sepsis. On hospital day (HD) 1, tests revealed a WBC count of 1.8 k/mcL, an erythrocyte sedimentation rate of 53 mm/hr (normal: 20-30 mm/hr for women, 15-20 mm/hr for men), and a C-reactive protein level of 6.7 mg/dL (normal: <0.5 mg/dL). A repeat chest x-ray and orofacial computerized tomography scan were normal. By HD 3, all bacterial cultures were negative, but the patient was positive for human herpesvirus-6 on viral cultures. His leukopenia persisted and he had elevated levels of alanine transaminase ranging from 40 to 73 U/L (normal: 6-43 U/L) and aspartate aminotransferase ranging from 66 to 108 U/L (normal range: 10-40 U/L), both downtrending during his hospitalization. He also had elevated levels of antinuclear antibodies and anti-Smith antibody titers. A posterior-auricular biopsy was consistent with lymphocytic perivasculitis. The rash continued to progress, involving his chest, abdomen, and face. Bacterial and viral cultures remained negative and on HD 4, broad-spectrum antibiotics were

    Full Text Available Abstract Background In recent years inhibitors directed against the epidermal growth factor receptor (EGFR have evolved as effective targeting cancer drugs. Characteristic papulopustular exanthemas, often described as acneiform rashes, are the most frequent adverse effect associated with this class of novel cancer drugs and develop in > 90% of patients. Notably, the rash may significantly compromise the patients' quality of life, thereby potentially leading to incompliance as well as dose reduction or even termination of the anti-EGFR therapy. Yet, an effective dermatologic management of cutaneous adverse effects can be achieved. Whereas various case reports, case series or expert opinions on the management of EGFR-inhibitor (EGFRI induced rashes have been published, data on systematic management studies are sparse. Methods Here, we present a retrospective, uncontrolled, comparative study in 49 patients on three established regimens for the management of EGFRI-associated rashes. Results Strikingly, patients' rash severity improved significantly over three weeks of treatment with topical mometason furoate cream, topical prednicarbate cream plus nadifloxacin cream, as well as topical prednicarbate cream plus nadifloxacin cream plus systemic isotretinoin. Conclusions In summary our results demonstrate that EGFRI-associated rashes can be effectively managed by specific dermatologic interventions. Whereas mild to moderate rashes should be treated with basic measures in combination with topical glucocorticosteroids or combined regiments using glucocorticosteroids and antiseptics/antibiotics, more severe or therapy-resistant rashes are likely to respond with the addition of systemic retinoids.

    The aim of the study was to investigate the application of hydrocolloid dressings in the prevention and treatment of infant diaper rash. A total of 210 infants with diaper rash were included in the study and randomized into 3 groups of 70 infants. Infants in group A received hydrocolloid dressings and individualized nursing; infants in group B received mupirocin plaster and topical application of pearl powder as well as routine nursing; and infants in group C received zinc oxide plaster and routine nursing. The clinical efficacy, incidence of adverse events, time to resolution of diaper rash, hospitalization duration, mean cost and satisfaction of nursing were compared between the 3 groups. After 1 cycle of treatment and nursing, the difference in the healing rate of mild diaper rash between groups A, B and C was significant (Pdiaper rash between groups A, B and C was significant (Pdiaper rash, hospitalization duration and cost in infants were not significantly different (Pdiaper rash effectively, decrease the incidence of adverse reactions significantly, shorten time to resolution of diaper rash and hospitalization duration, reduce mean hospitalization cost, improve parent satisfaction and promote nursing-patient harmony. Thus, this method of treatment was worthy of clinical application. PMID:28101161

    Human parvovirus B19 (B19V) infection in immunocompetent patients usually has a mild clinical course, but during pregnancy it can cause serious and even fatal complications in the fetus. The most common clinical presentation of B19V infection is erythema infectiosum and in this case laboratory confirmation is required for differentiation from other exanthematous diseases. Measles and rubella negative sera collected in Belarus between 2005 and 2008 from 906 patients with a rash and fever were screened for B19V infection by ELISA. More than 35% of the samples (322/906) were positive for B19V. The proportion ranged from 10.1% in 2008 to 53.2% in 2006 when an outbreak took place in Minsk city. All B19V outbreaks and cluster cases occurred during the winter-spring period, but sporadic cases were recorded basically throughout the year. The majority of the cases (56.5%) occurred among the 2 till 10 year old children, and 27.3% of the cases were observed in adults between 19 and 53 years. All 104 B19V strains sequenced in the NS1/VP1u region belonged to genotype 1 with a maximal genetic distance of 1.75%. The two phylogenetic clusters reflected the geographic origins of the viruses within the country. Forty-two unique nucleotide mutations as compared to sequences downloaded from GenBank were found in the VP1u and NS1 regions; most of these changes were nonsynonymous. This report highlights the importance of B19V infection in patients with a rash and fever in Belarus.

  7. Incidence and determinants of nevirapine and efavirenz-related skin rashes in West Africans: nevirapine's epitaph?

    Directory of Open Access Journals (Sweden)

    Fred Stephen Sarfo

    Full Text Available Non-nucleoside reverse transcriptase inhibitor (NNRTI associated rash is common and frequently leads to discontinuation of NNRTIs. This study assessed the risk of developing rashes and discontinuing NNRTIs and associated factors in a large clinic in central Ghana. In this retrospective cohort study, clinical data were obtained in patients starting efavirenz or nevirapine between 2004-2010. Factors associated with rashes were explored using a multivariate Cox proportional hazards regression model. Of 3,999 patients who started NNRTI-based ART, 281 (7.0% experienced at least one episode of NNRTI-related rash with an incidence of 2.63 events/100 person-years, occurring in 10.2% and 5.6% of patients taking nevirapine and efavirenz respectively. Most rashes (94% were grade 1 or 2 and were reported a median of 2 months following initiation of ART. In multivariate analysis developing a rash was associated with nevirapine use (aHR 1.67, 95% CI 1.28-2.10, female gender (aHR of 1.39, 95% CI 1.01-1.92 and lower baseline CD4 counts (aHR 0.88, 95% CI 0.82-0.95 per 50 cells/mm³ increment. Patients with nevirapine-associated rash were 11 times more likely to discontinue treatment as patients with efavirenz-associated rash. In contrast to findings in other studies, NNRTI-associated rashes in Ghanaians appear more common in patients with lower baseline CD4 counts. Given the increased frequency of rashes with nevirapine and subsequent discontinuations in many patients, along with other treatment-limiting toxicities, this provides further impetus for the replacement of nevirapine by efavirenz as the first-line NNRTI treatment of choice in Africa.

    The number of women entering medicine has increased significantly, yet women are still under-represented at senior levels in academic medicine. To support the gender equality action plan at one School of Medicine, this study sought to (1) identify the range of viewpoints held by staff on how to address gender inequality and (2) identify attitudinal barriers to change. Q methodology. 50 potential interventions representing good practice or positive action, and addressing cultural, organisational and individual barriers to gender equality, were ranked by participants according to their perception of priority. The School of Medicine at the University of Leeds, UK. Fifty-five staff members were purposively sampled to represent gender and academic pay grade. Principal components analysis identified six competing viewpoints on how to address gender inequality. Four viewpoints favoured positive action interventions: (1) support careers of women with childcare commitments, (2) support progression of women into leadership roles rather than focus on women with children, (3) support careers of all women rather than just those aiming for leadership, and (4) drive change via high-level financial and strategic initiatives. Two viewpoints favoured good practice with no specific focus on women by (5) recognising merit irrespective of gender and (6) improving existing career development practice. No viewpoint was strongly associated with gender, pay grade or role; however, latent class analysis identified that female staff were more likely than male to prioritise the setting of equality targets. Attitudinal barriers to the setting of targets and other positive action initiatives were identified, and it was clear that not all staff supported positive action approaches. The findings and the approach have utility for those involved in gender equality work in other medical and academic institutions. However, the impact of such initiatives needs to be evaluated in the longer term.

    Transgenic mice carrying the human prototype c-Ha-ras gene (rasH2 mice) are highly susceptible to lung carcinogens. In order to investigate the possibility of developing a rapid in vivo assay for lung carcinogens, we examined whether the tumor-promoting activity of butylhydroxytoluene (BHT) is efficacious in rasH2 mice. rasH2 mice and wild littermates of both genders were pre-treated with carcinogens [urethane (UR), 4-nitroquinoline 1-oxide (4NQO) or diethylnitrosamine (DEN)], and, one day later, given a 400 mg/kg dose of BHT. Six weeks after the initiation treatment, evidence of carcinogenicity could be detected in male and female rasH2 mice that had received UR doses of > or = 250 mg/kg and > or = 125 mg/kg, respectively, prior to exposure to BHT, whereas only 500 mg/kg of UR was sufficient to induce tumors in female rasH2 mice given the carcinogen alone. The carcinogenicity of 15 mg/kg of 4NQO could be detected after 9 weeks in male rasH2 mice given the carcinogen followed by BHT. Similarly, the carcinogenicity of 60 mg/kg of DEN could be detected after 9 weeks and 6 weeks, respectively, in male and female rasH2 mice given the carcinogen followed by BHT. No carcinogenicity could be demonstrated through the experimental period with doses of 4NQO or DEN given alone. These results indicate that BHT administration increases the susceptibility of rasH2 mice to lung carcinogens, and suggest that the use of BHT in rasH2 mice might lead to the establishment of a rapid in vivo assay for lung carcinogens.

    Generalized pruritic rash in Hodgkin’s disease is most commonly due to paraneoplastic manifestation. It can sometimes precede other manifestations of Hodgkin’s disease by weeks or months. Hence, if other possible causes have been ruled out, Hodgkin’s disease should be considered a possible cause of generalized pruritic rash. Consideration of Hodgkin’s disease as a cause of generalized pruritic rash can help in early identification of Hodgkin’s disease. We present a case of a 71-year-old femal...

  17. Self research in educational psychology: a cautionary tale of positive psychology in action.

    Science.gov (United States)

    Martin, Jack

    2006-07-01

    Recent calls for a positive psychology that would deemphasize human pathology and dysfunction in favor of building an understanding of positive features of human life and human flourishing make two assumptions that the author questions in this article. First, he challenges the assumption that disciplinary psychology has been fixated on pathology and dysfunction by considering work in educational psychology that, both historically and currently, espouses the characteristics of positive psychology as articulated by its major advocates. Second, through a brief, critical consideration of research on the self in educational psychology, he contests the assumption that psychology has sufficient resources to develop into the positive psychology envisioned by its promoters. He argues that psychology's emphasis on the individual, whose core self resides in a deep, internal psyche, radically strips psychology of the historical and sociocultural resources that enable self-development, constrain self-understanding, and constitute the self.

    This case series describes morbilliform and other rash presentations among schoolchildren during a March 2014 outbreak of influenza-like illness (ILI) in British Columbia, Canada. Multiplex nucleic acid testing of nasopharyngeal specimens and paired serologic investigations identified that influenza B, characterized as B/Massachusetts/02/2012-like (Yamagata-lineage), was the only viral aetiology and most likely cause of ILI and rash. An association between influenza B and rash has been described infrequently elsewhere, and not previously in North America. Influenza B should be considered in the differential diagnosis of febrile exanthem. Evaluation of the nature, incidence and contributing agent-host-environment interactions, and immunologic mechanisms to possibly explain influenza-associated rash is warranted. © 2014 The Authors.

    In the summer of 2006, an Amblyomma americanum tick was removed from a woman in central North Carolina, who subsequently developed a rash at the site of tick attachment. When examined by polymerase chain reaction (PCR) for Borrelia, Anaplasma, Ehrlichia, Babesia, Rickettsia, and Bartonella DNA, only the Rickettsia primers generated an amplicon, which was identified as "R. amblyommii" by sequencing. To our knowledge, this is the first case in which R. amblyommii was temporally associated with a rash.

    Cercenado, Emilia

    2017-01-01

    Because of the increase in bacterial resistance, there is a need for new antimicrobial agents. Dalbavancin is a semisynthetic glycopeptide that inhibits the late stages of bacterial cell wall synthesis in the same way as vancomycin, but in addition, its lipophilic side chain anchors dalbavancin to the cellular membrane and allows enhanced activity compared with that of vancomycin. Dalbavancin possesses a broad spectrum of in vitro activity against Gram-positive aerobic and anaerobic microorganisms, being 4-8 times more potent than vancomycin. The spectrum of dalbavancin includes staphylococci, enterococci, streptococci, and anaerobic Gram-positive cocci and bacilli. It is active against different species of multiresistant microorganisms, including methicillin-resistant Staphylococcus aureus and penicillin-resistant viridans streptococci and Streptococcus pneumoniae. Although it shows in vitro activity against Enterococcus spp., it is inactive against isolates expressing the VanA phenotype of vancomycin resistance. It also shows slow bactericidal activity against S. aureus, coagulase-negative staphylococci, and Streptococcus pyogenes. In general, the MIC90 (minimum inhibitory concentration 90%) against the majority of the microorganisms is 0.06mg/L and, more than 98% of the isolates that have been tested are inhibited at concentrations of ≤ 0.12mg/L. Dalbavancin is an interesting addition to the therapeutic armamentarium for the treatment of infections caused by Gram-positive microorganisms, including multidrug-resistant isolates.

    Neuromyelitis optica is associated with severe neurodisability if not recognized and treated promptly. Several autoimmune disorders are associated with this condition and may vary in their presentation. It is essential that clinicians are aware of the uncommon presenting features of neuromyelitis optica and associated autoimmune conditions. A 53-year-old woman presented with nausea and vomiting and was noted to have an asymptomatic elevated creatinine kinase level, which improved with conservative management. She had a history of iron-deficiency anemia due to long-standing celiac disease that was managed with a gluten-free diet. She then presented with recurrent transverse myelitis and a vesicobullous rash over her arms and feet that was pruritic and excoriating. Skin biopsy results confirmed a clinical diagnosis of dermatitis herpetiformis and antibody test findings against aquaporin-4 were positive, leading to a diagnosis of neuromyelitis optica spectrum disorder. She was treated with methylprednisolone sodium succinate, plasma exchange, and azathioprine and has remained in remission. This report highlights the association of neuromyelitis optica with dermatitis herpetiformis, which can present even without clinical features of celiac disease. Nausea, vomiting, and asymptomatic hyperCKemia should be recognized as rare presenting features of neuromyelitis optica.

    The health effects of climate change have had relatively little attention from climate scientists and governments. Climate change will be a major threat to population health in the current century through its potential effects on communicable disease, heat stress, food and water security, extreme weather events, vulnerable shelter and population migration. This paper addresses three health-sector strategies to manage the health effects of climate change-promotion of mitigation, tackling the pathways that lead to ill-health and strengthening health systems. Mitigation of greenhouse gas (GHG) emissions is affordable, and low-carbon technologies are available now or will be in the near future. Pathways to ill-health can be managed through better information, poverty reduction, technological innovation, social and cultural change and greater coordination of national and international institutions. Strengthening health systems requires increased investment in order to provide effective public health responses to climate-induced threats to health, equitable treatment of illness, promotion of low-carbon lifestyles and renewable energy solutions within health facilities. Mitigation and adaptation strategies will produce substantial benefits for health, such as reductions in obesity and heart disease, diabetes, stress and depression, pneumonia and asthma, as well as potential cost savings within the health sector. The case for mitigating climate change by reducing GHGs is overwhelming. The need to build population resilience to the global health threat from already unavoidable climate change is real and urgent. Action must not be delayed by contrarians, nor by catastrophic fatalists who say it is all too late.

    We report two cases, one of a 52-year-old man and one of a 32-year-old man, who were treated with cefotaxime. On day 23 and day 28 of the treatment, respectively, the patients manifested clinically with fever, pruriginous skin rash, and facial edema. Blood tests showed marked eosinophilia and atypical lymphocytosis for both patients, and hepatic cytolysis only in the second patient. Cefotaxime was discontinued in both patients; the clinico-biological picture improved gradually and completely disappeared approximately 4 weeks later. Six weeks after complete recovery, both patients underwent intradermal testing which was positive to cefotaxime (2 mg/ml) at the 48-hour reading and negative to benzylpenicillin, amoxicillin, and cefazolin at the 20-minute and 48-hour readings. These clinical pictures suggest drug rash with eosinophilia and systemic symptoms (DRESS) induced by cefotaxime. To the best of our knowledge, only one case of cefotaxime-induced DRESS has been reported in the medical literature. Thus, we add two new cases of cefotaxime-induced DRESS and emphasize the usefulness and safety of intradermal testing in establishing the diagnosis.

    The aim of this study was to analyze indicators of technical actions (ITA and intensity according to the players positions in six official matches of the Brazilian Basketball League. Ten elite basketball male players participated in this study (27.60±5.54years. The total frequency of matches’ indicators (∑MI - sum of all matches indicators of each athlete included in the stats and the efficiency ratio (ER from matches’ official stats were the ITA considered. To check the intensity, athletes played with HR transmitter. Were produced descriptive measures; and the magnitude of difference (Δ% between ∑MI and ER second player [Δ%=(1-(ER÷∑MI*100] was calculated. It was observed that when players were classified by Δ% they were automatically classified by their respective positions in 80% of cases. Players’ positions 4 and 5 work closer to the basket and perform the safest and most efficient team play; players’ position 1 plays facing to the basket, organizes the collective game, has the largest ball possession volume which can also enable a safer game. Players' position 5 had higher Δ% between ∑MI and ER, representing safer and efficient game; older players had lower intensity; and the basketball game was developed on average slightly above the lactate threshold HR.

    In this paper,two kinds of skew derivations of a type of Nichols algebras are introduced,and then the relationship between them is investigated.In particular they satisfy the quantum Serre-relations.Therefore,the algebra generated by these derivations and corresponding automorphisms is a homomorphic image of the Drinfeld-Jimbo quantum enveloping algebra μq(g),which proves the Nichols algebra becomes aμq(g)-module algebra.But the Nichols algebra considered here is exactly μq+(g),namely,the positive part of the Drinfeld-Jimbo quantum enveloping algebra μq(g),it turns out that μq+(g)is a μq(g)-module algebra.

    Herpes zoster is a common disorder characterized by a painful rash along a dermatome caused by reactivation of the varicella zoster virus (VZV). Muscle denervation injury from motor involvement is an uncommon phenomenon. Discordant distribution of the skin rash and motor nerve involvement, presenting as a skin rash in one body part and muscle weakness or pain from nerve involvement in another body part is an even more uncommonly reported finding. We present an unusual case of muscle denervation injury resulting from motor involvement of a peripheral nerve by VZV diagnosed by magnetic resonance imaging with cutaneous manifestations in a different dermatomal distribution. To the best of our knowledge, there has been no similar case reported in the English radiology literature. We suggest that whenever a radiologist notices MRI findings suggesting denervation injury and a cause not readily identified, VZV-related denervation injury should be included in the differential diagnosis, especially in an older immunocompromised patient.

    Drug Rash (or Reaction) with Eosinophilia and Systemic Symptoms (DRESS) is a potentially life-threatening hypersensitivity reaction to drugs characterized by rash, fever, lymphadenopathy, hematologic abnormalities, and involvement of internal organs. Initially coined in 1996, the term is used to refer to an idiosyncratic reaction to several drugs, the most common of which are carbamazepine, allopurinol, sulfasalazine, and phenobarbital. We report the first case of DRESS related to rufinamide in a ten year old boy with a history of a complex seizure disorder.

    Full Text Available Legionella pneumophila is the most common cause of legionellosis and is one of the organisms causing atypical pneumonia. We report the presentation of disseminated intravascular coagulation (DIC and skin rash in a single case of severe Legionella pneumonia. The unique clinical presentation of a diffuse rash diagnosed as purpura fulminans and the unpredictable variations encountered during the diagnostic work-up of the case make this write-up crucial. This article synthesizes all reported cases of L. pneumonia associated with cutaneous manifestations as well as cases presenting with DIC. Furthermore, this manuscript illustrates the correlation between cutaneous and coagulopathic manifestations, and morbidity and mortality from L. pneumonia.

    We describe challenges in the 6-year longitudinal cluster randomized controlled trial (CRCT) of Positive Action (PA), a social-emotional and character development (SECD) program, conducted in 14 low-income, urban Chicago Public Schools. Challenges pertained to logistics of study planning (school recruitment, retention of schools during the trial, consent rates, assessment of student outcomes, and confidentiality), study design (randomization of a small number of schools), fidelity (implementation of PA and control condition activities), and evaluation (restricted range of outcomes, measurement invariance, statistical power, student mobility, and moderators of program effects). Strategies used to address the challenges within each of these areas are discussed. Incorporation of lessons learned from this study may help to improve future evaluations of longitudinal CRCTs, especially those that involve evaluation of school-based interventions for minority populations and urban areas.

    We previously reported the activities and modes of action of arginine (Arg)-rich histones H3 and H4 against Gram-negative bacteria. In the present study, we investigated the properties of the Arg-rich histones against Gram-positive bacteria in comparison with those of lysine (Lys)-rich histone H2B. In a standard microdilution assay, calf thymus histones H2B, H3, and H4 showed growth inhibitory activity against Staphylococcus aureus with minimum effective concentration values of 4.0, 4.0, and 5.6 μM, respectively. Laser confocal microscopic analyses revealed that both the Arg-rich and Lys-rich histones associated with the surface of S. aureus. However, while the morphology of S. aureus treated with histone H2B appeared intact, those treated with the histones H3 and H4 closely resembled each other, and the cells were blurred. Electrophoretic mobility shift assay results revealed these histones have binding affinity to lipoteichoic acid (LTA), one of major cell surface components of Gram-positive bacteria. Scanning electron microscopic analyses demonstrated that while histone H2B elicited no obvious changes in cell morphology, histones H3 and H4 disrupted the cell membrane structure with bleb formation in a manner similar to general antimicrobial peptides. Consequently, our results suggest that bacterial cell surface LTA initially attracts both the Arg- and Lys-rich histones, but the modes of antimicrobial action of these histones are different; the former involves cell membrane disruption and the latter involves the cell integrity disruption.

    Full Text Available As a result of successful implementation of the measles/rubella elimination program, the etiology of more and more double negative cases remains elusive. The present study determined the role of different viruses as causative agents in measles or rubella suspected cases in Belarus. A total of 856 sera sent to the WHO National Laboratory between 2009 and 2011 were tested for specific IgM antibodies to measles virus (MV, rubella virus (RV and human parvovirus B19 (B19V. The negatives were further investigated for antibodies to enterovirus (EV and adenovirus (AdV. Children of up to 3 years were tested for IgM antibodies to human herpesvirus 6 (HHV6. A viral etiology was identified in 451 (52.7% cases, with 6.1% of the samples being positive for MV; 2.6% for RV; 26.2% for B19V; 9.7% for EV; 4.6% for AdV; and 3.6% for HHV6. Almost all measles and rubella cases occurred during limited outbreaks in 2011 and nearly all patients were at least 15 years old. B19V, EV and AdV infections were prevalent both in children and adults and were found throughout the 3 years. B19V occurred mainly in 3-10 years old children and 20-29 years old adults. EV infection was most common in children up to 6 years of age and AdV was confirmed mainly in 3-6 years old children. HHV6 infection was mostly detected in 6-11 months old infants. Laboratory investigation of measles/rubella suspected cases also for B19V, EV, AdV and HHV6 allows diagnosing more than half of all cases, thus strengthening rash/fever disease surveillance in Belarus.

Almost all measles and rubella cases occurred during limited outbreaks in 2011 and nearly all patients were at least 15 years old. B19V, EV and AdV infections were prevalent both in children and adults and were found throughout the 3 years. B19V occurred mainly in 3-10 years old children and 20-29 years old adults. EV infection was most common in children up to 6 years of age and AdV was confirmed mainly in 3-6 years old children. HHV6 infection was mostly detected in 6-11 months old infants. Laboratory investigation of measles/rubella suspected cases also for B19V, EV, AdV and HHV6 allows diagnosing more than half of all cases, thus strengthening rash/fever disease surveillance in Belarus.

    Topical medications are frequently neglected as the potential cause of systemic drug reactions. In this case report, a patient with a maculopapular eruption attributed to a drug hypersensitivity reaction was submitted to skin patch tests in order to clarify the drug implicated. Incidentally, a positive reaction to cinchocaine was observed. With the ulterior confirmation of the application of an antihemorrhoidal ointment containing cinchocaine, which was omitted during the initial anamnesis, the diagnosis of systemic contact dermatitis to cinchocaine was made.

    Full Text Available Meningitis caused by varicella zoster virus (VZV is rare in healthy population. Predominantly immunocompromised patients are affected by reactivation of this virus with primary clinical features of rash and neurological symptoms. Here we report a young otherwise healthy man diagnosed with a VZV meningitis without rash. He complained of acute headache, nausea, and vomiting. The clinical examination did not show any neurological deficits or rash. Cerebrospinal fluid (CSF analysis revealed a high leukocyte cell count of 1720 cells/µL and an elevated total protein of 1460 mg/L misleadingly indicating a bacterial infection. Further CSF analyses, including polymerase chain reaction (PCR and detection of intrathecal synthesis of antibodies, showed a VZV infection. Clinical and CSF follow-up examinations proved the successful antiviral treatment. In conclusion, even young immunocompetent patients without rash might present with VZV meningitis. CSF examination is a key procedure in the diagnosis of CNS infections but in rare cases the standard values cell count and total protein might misleadingly indicate a bacterial infection. Thus, virological analyses should be considered even when a bacterial infection is suspected.

    The antibacterial activity of royalisin, an antimicrobial peptide from the royal jelly produced by honeybees, has been addressed extensively. However, its mechanism of action remains unclear. In this study, a recombinant royalisin, RAcc-royalisin from the royal jelly of Asian honeybee Apis cerana cerana, was expressed by fusing with glutathione S-transferase (GST) in Escherichia coli BL21, isolated and purified. The agar dilution assays with inhibition zone showed that RAcc-royalisin, similar to nisin, inhibits the growth of Gram-positive bacteria. The antibacterial activity of RAcc-royalisin was associated with its concentration, and was weakened by heat treatment ranging from 55°C to 85°C for 15 min. Both RAcc-royalisin and nisin exhibited the minimum inhibitory concentrations (MIC) of 62.5 µg/ml, 125 µg/ml, and 250 µg/ml against Gram-positive bacterial strains, Bacillus subtilis and Micrococcus flavus and Staphyloccocus aureus in the microplate assay, respectively. However, RAcc-royalisin did not show antimicrobial activity against tested Gram-negative bacterial and fungal strains. The antibacterial activity of RAcc-royalisin agrees well with the decrease in bacterial cell hydrophobicity, the leakage of 260-nm absorbing materials, and the observation by transmission electron microscopy, all indicating that RAcc-royalisin induced the disruption and dysfunction of cell walls and membranes. This is the first report detailing the antibacterial mechanism of royalisin against Gram-positive bacteria, and provides insight into the application of recombinant royalisin in food and pharmaceutical industries as an antimicrobial agent.

    To assess whether the cutaneous features in patients with dengue fever are associated with abnormal blood biochemistry, complications, and poor disease outcome. Forty five patients with dengue fever were identified at a medical center in Kaohsiung, Taiwan, from September to November 2014. All cases were exclusively caused by type 1 dengue virus. Patients were classified into two groups, based on the presence or absence of skin rash, and their rash was subclassified into maculopapular, morbilliform, and petechial types. Clinical symptoms, laboratory data, disease outcome, and complications were compared between the two groups. Thirty two patients with dengue fever developed skin rash (SP group, n = 32) while the rest of 13 did not (SN group, n = 13). The patient numbers in the maculopapular, morbilliform, and petechial group were 4, 21, and 7, respectively. The SP group was younger (P = 0.001), experienced more pruritus (P = 0.008) and more swollen palms/soles (P = 0.015) than the SN group. However, the SN group had greater genital mucosa involvement (P = 0.008), higher platelet transfusion rate (P = 0.003), and lower hemoglobin and hematocrit levels (P = 0.030) than the SP group. Patients with morbilliform lesions had a higher incidence of palm/sole swelling, less genital mucosal involvement, and a lower platelet transfusion rate than did patients with maculopapular or petechial lesions. Cutaneous manifestations provide an important clue to dengue fever. In patients with dengue fever, those with skin rash tend to have itching and swelling of the palms/soles, however, those without skin rash tend to have more complications and poor disease outcomes.

    2015-01-01

    We observed late-onset rashes in patients with group A beta-hemolytic streptococcal (GAS) pharyngitis. Of 1028 patients with GAS pharyngitis, which was principally treated with amoxicillin, we evaluated those who developed a late-onset rash and excluded those with scarlet fever alone. Twenty-one patients developed a rash (2.0%, 95% confidence interval, 1.3-3.1%), 7 to 20 days (median, 8 days) after GAS pharyngitis onset. The rashes were characterized by maculopapules, which increased in size with coalescence and some developing into plaques, with a symmetrical distribution with a propensity for the extremities, including the palms and soles. The clinical courses of the patients were good, and the rashes subsided within 14 days. A non-immediate reaction to β-lactams, which usually manifests as a maculopapular rash, is a possible cause in our patients, however, repeated courses of amoxicillin in 3 patients did not induce the rash. The underlying mechanism of the late-onset rash after GAS pharyngitis with amoxicillin treatment remains unclear. PMID:26734124

    Cutaneous eruption around a peritoneal dialysis (PD) catheter exit site is a rare complication. Herein we report a case of bullous eruption; we discuss the diagnostic approach and the related therapeutic implications. A 63-year-old man presented a bullous periumbilical eruption two months after initiation of PD. Cultures of laboratory samples ruled out an infectious origin and systemic corticosteroids initiated at 0.5mg/kg for suspected eosinophilic peritonitis produced significant improvement of the cutaneous eruption. Recurrence of the bullous eruption was observed upon dose-reduction of the corticosteroid. Skin histology showed a clinical picture of eczema and direct immunofluorescence was negative. Patch testing was carried out using the European Standard Battery comprising antiseptic, cosmetic and plastic series; a semi-open test was performed with the dressing used for PD, and ROAT was carried out on the povidone iodine (Betadine™) 10% used for topical care during PD. The patch testing and ROAT were positive (++), confirming contact dermatitis due to Betadine™. The eruption totally disappeared on substitution of Betadine™ by chlorhexidine for topical antisepsis of the PD catheter, thus enabling PD to be continued rather than instituting hemodialysis. Allergic contact dermatitis around a PD catheter is a rare and little-known complication. In the present case, ROAT testing showed sensitization to Betadine™ and enabled an alternative antisepsis solution to be found, allowing PD to be continued. Copyright © 2015 Elsevier Masson SAS.

    Positive Action (PA) is a school-based intervention for elementary-, middle-, and high-school students that aims to decrease problem behaviors (e.g., violence, substance use) and increase positive behaviors (e.g., academic achievement, school engagement). PA has a long history of documented success achieving these aims, making it an Evidence Based Practice (EBP). Intervention research on EBP's has established the importance of implementation fidelity, especially with regard to program dosage; failure to properly implement an EBP can have negative consequences on targeted outcomes, especially if participants are exposed to a low dosage of the program (e.g., fewer lessons than specified). Much of the current research on PA has neglected to examine how program dosage impacts PA's effect on targeted outcomes. Using propensity score models, multiple imputation, and a 2-level hierarchical linear model, the current study fills this gap and examines how different dosages of PA as measured by years participating in PA and number of PA lessons, impacts adolescent internalizing symptoms, aggression, perceptions of school hassles, and self-esteem over a 3-year period. The current sample included middle school students in grades 6, 7, and 8 (N = 5,894). The findings indicate that students who received 3 years of the PA intervention and a high number of PA lessons had a significantly higher self-esteem score than those who received 0 years of PA or zero lessons. Participants who received 1 year of PA also reported significantly lower school hassle scores than those who received 0 years. Dosage had no statistically significant effects on aggression or internalizing score. Implications are discussed. (PsycINFO Database Record

    Full Text Available Cutaneous rash is one of the commonest adverse events associated with lamotrigine. We assessed whether the risk is increased in patients receiving concomitant valproate therapy in a population of 103 adult patients with intractable epilepsy, who had lamotrigine added to their treatment. Of the 33 patients taking valproate, 10 (30% developed a rash, whilst of the 70 not taking valproate, only 6 (8% developed a rash. This suggests a significantly higher risk of cutaneous rash when starting lamotrigine in patients already taking valproate (pRash cutâneo é um dos efeitos adversos mais comuns associados ao início de tratamento com lamotrigina, uma nova medicação antiepiléptica.

    The application of carbon nanotubes (CNTs) as biomaterials is of wide interest, and studies examining their application in medicine have had considerable significance. Biological safety is the most important factor when considering the clinical application of CNTs as biomaterials, and various toxicity evaluations are required. Among these evaluations, carcinogenicity should be examined with the highest priority; however, no report using transgenic mice to evaluate the carcinogenicity of CNTs has been published to date. Here, we performed a carcinogenicity test by implanting multi-walled CNTs (MWCNTs) into the subcutaneous tissue of rasH2 mice, using the carbon black present in black tattoo ink as a reference material for safety. The rasH2 mice did not develop neoplasms after being injected with MWCNTs; instead, MWCNTs showed lower carcinogenicity than carbon black. Such evaluations should facilitate the clinical application and development of CNTs for use in important medical fields.

    Herpes zoster ophthalmicus, in which orbital symptoms and signs appear before the onset of a skin rash, is very rare. We experienced such a case and therefore report on it via magnetic resonance imaging. A 48-year-old man with pain and swelling of left eye and headache presented 2 days before onset of a zoster skin rash. On orbit-al MRI, edematous thickening of the left lateral rectus muscle with high signal intensity was revealed. After contrast injection, the lateral rectus muscle demonstrated heterogenous enhancement. Also, diffuse contrast enhancement was noted at left preseptal space, lacrimal gland and periorbital soft tissue. The man was treated with antiviral agents and prednisolone. Two weeks later, he recovered from the skin manifestations and most of the orbital manifestations except for the diplopia and restricted lateral movement.

    Full Text Available Background: Diaper Rash is a common skin disorder in the infancy that makes infants and their parents anxious and nervous. Due to the high prevalence of dermatitis and its complications in addition to adverse effects of chemical drugs, herbal therapy is an appropriate solution. Aim: Comparison of the effects of Chamomile and Calendula ointments on severity of Diaper Rash. Methods: This double-blind randomized controlled trial was conducted on 90 infants under one year who were hospitalized in Sabalan Hospital of Ardebil. The infants were treated by Chamomile and Calendula ointments for one week. The severity of dermatitis was evaluated on days one, 3 and 7.  In order to assess the severity of dermatitis, the checklist of Diaper Rash five-point scale was used. Data were analyzed by software SPSS version 14 using chi-square, ANOVA, T-Test. Results: The age in the Chamomile group was (8. 8 ± 2.3 and in Calendula group was (9.0± 2.4 months. The severity of dermatitis in Chamomile group before treatment was 1.6 ± 0.5, on the third day 0.8 ± 0.4, and on the seventh day zero (p

    Full Text Available DRESS syndrome (drug rash with eosinophilia and systemic symptoms is a severe adverse drug reaction characterised by rash, fever, lymphadenopathy and internal organ involvement. Although the death rate can reach 10%, rapid diagnosis and prompt withdrawal of the offending drug is the key to limit morbidity and mortality. The potential role of corticosteroids remains controversial. We report a case of a 45-year-old male patient who suffered a head injury, for which he was prescribed phenytoin. Five weeks later he developed features of DRESS syndrome including facial and peri-orbital oedema, generalized erythematous, maculo-papular rash, conjunctivitis, inguinal lymphadenopathy, leucocytosis, eosinophilia and elevated liver enzymes. Skin biopsy revealed acanthosis and spongiosis of epidermis and dense inflammatory cell infiltrate comprising eosinophils and lymphocytes. In this case, causalty assessment using Naranjo adverse drug reaction probability scale showed that phenytoin was a probable cause for the adverse drug reaction (score-7. Phenytoin was immediately stopped and patient was treated with systemic corticosteroids. The patient improved dramatically within the next few days. Early recognition of symptoms of DRESS and immediate withdrawal of the offending drug followed by prompt treatment with corticosteroids and other supportive measures will ensure quick recovery and will avoid fatal outcomes.

    Positive Action is a school-based program that aims to decrease problem behaviors (e.g., violence, substance use) and increase positive behaviors (e.g., school engagement, academic achievement). Although a number of studies have shown that Positive Action successfully achieves these goals, few studies have evaluated the program's effectiveness in rural schools. Given that rural youth are at an increased risk for risky behaviors (e.g., violence, substance use), this is a critical gap in the existing Positive Action research base. The current study assesses the impact of Positive Action on change rates of self-esteem, school hassles, aggression, and internalizing symptoms in a group (N = 1246, 52% female) of ethnically/racially diverse (27% White, 23% African American, 12% mixed race/other, 8% Latino, 30% as American Indian) middle school youth (age range 9-20) located in two violent, low-income rural counties in North Carolina. One county engaged in Positive Action over the 3-year study window while the other county did not. Following multiple imputation and propensity score analysis, 4 two-level hierarchical linear models were run using each of the outcome measures as dependent variables. The results indicate that the program generates statistically significant beneficial effects for youth from the intervention county on self-esteem scores and school hassles scores. Although the program generates beneficial effects for intervention youth on the change in aggression scores, the finding is not statistically significant. The finding on the change in internalizing scores shows a non-significant detrimental effect: the youth from the comparison county have lower internalizing scores than those from the intervention county. Implications are discussed.

    The aim of the study is to evaluate the prevalence of specific antibodies anti-human parvovirus B19 (PVB19) immunoglobulin M (IgM) and IgG in children with fever and rash. This study involved 257 children aged from 7 months to 15 years with febrile rash unrelated to measles and rubella (seronegative for IgM). The sera were examined by immunoenzymatic assay. Detection of antibodies of PVB19 was done by enzyme-linked immunosorbent assay (Elisa). In our study, prevalence of immunoglobulin G (IgG) and IgM were 44 and 11.3%, respectively. Clinically, children with positive IgM serology had submitted an erythema infectiosum (13/29 cases), myocarditis (1 case), encephalitis (1 case), severe sickle cell anemia (7 cases), and immunocompromised (7 cases). The incidence rate of viral infection was 11.3%; most of the cases of PVB19 infection occurred between the months of May and August. Incidence was higher in the 10-15 years age group (21%). The prevalence of IgG antibody varied and increased with age, it rises from 38.2% in preschool children (19 months-4 years) to 53.5% in those aged between 4.5 and 15 years, reaching 58% in the 10-15 years age group. The four risk factors of PVB19 infection are: (1) those aged between 4.5 and 9 years, which is the most affected age group (P = 0.0018); (2) female gender in children aged between 19 months and 4 years (P = 0.037); (3) transfusion and (4) immune deficiency (P = 0.022 and P = 0.001, respectively). The study of the prevalence of PVB19 infection shows that viral infection is acquired early in childhood, increases with age; viral transmission is favored by the community life. Because of the widespread vaccination program against measles and rubella, the systematic search of PVB19 in front of eruptive fevers becomes important.

  20. Differential Effects of Reward Drive and Rash Impulsivity on the Consumption of a Range of Hedonic Stimuli.

    Goodwin, Belinda C; Browne, Matthew; Rockloff, Matthew; Loxton, Natalie

    2016-06-01

    Background and aims Impulsivity has consistently been associated with over-consumption and addiction. Recent research has reconceptualized impulsivity as a two-dimensional construct ( Dawe, Gullo, & Loxton, 2004 ). This study explores the relationship of the two components of impulsivity, reward drive (RD) and rash impulsivity (RI), on a broad group of 23 hedonic consumption behaviors (e.g., gambling, substance use, eating, and media use). We tentatively grouped the behaviors into three descriptive classes: entertainment, foodstuffs, and illicit activities and substances. Results RD and RI positively predicted elevated levels of consumption in a community sample (N=5,391; 51% female), for the vast majority of the behaviors considered. However, the effect sizes for RD and RI varied significantly depending on the behavior; a pattern that appeared to be at least partially attributable to the class of consumption. Results support the view that RD is related more strongly to the consumption of products that provide social engagement or a sense of increased status; whereas RI better reflects an approach toward illicit or restricted products that are intensely rewarding with clear negative consequences. Discussion and conclusion Results support the utility of the two-factor model of impulsivity in explaining individual differences in patterns of hedonic consumption in the general population. We discuss findings in terms of strengthening current conceptualizations of RI and RD as having distinct implications with respect to health-related behaviors.

    Safety leadership is an important factor in supporting safe performance in the workplace. The present case study examined the role of safety leadership during the Bingham Canyon Mine high-wall failure, a significant mining incident in which no fatalities or injuries were incurred. The Critical Decision Method (CDM) was used in conjunction with a self-reporting approach to examine safety leadership in terms of decisions, behaviours and actions that contributed to the incidents' safe outcome. Mapping the analysis onto Rasmussen's Risk Management Framework (Rasmussen, 1997), the findings demonstrate clear links between safety leadership decisions, and emergent behaviours and actions across the work system. Communication and engagement based decisions featured most prominently, and were linked to different leadership practices across the work system. Further, a core sub-set of CDM decision elements were linked to the open flow and exchange of information across the work system, which was critical to supporting the safe outcome. The findings provide practical implications for the development of safety leadership capability to support safety within the mining industry. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. the temperature dropped to normal When Rash Had appeared For 12 Hours:an atypical Case of Measles in adult

    Institute of Scientific and Technical Information of China (English)

    2014-01-01

    A twenty-eight-year-old male patient with five-day’s fever (the highest body tempreture reached 39.4℃) and 10-hour’s rash (first on face) presented to the department of emergency for “drug rash”, at that time his temperature was 38.6℃. Two hours later, his temperature fell to normal. Then this patient’s entire body rash increased signiifcantly and lasted for 13 hours. Serum measles antibody IgM(+) conifrmed the measles diagnosis. He had received measles vaccine as a baby. Clinicians should be aware of this atypical clinical manifestation of adult measles. If this kind of patients were misdiagnosed as drug rash and given corticosteroid, measles disease may be aggravated. Speciifc serum measles antibody testing may be the only reliable method for differential diagnosis, but the earliest time point for examining the antibodies of measles still needs precise research.

    Leadership behaviour in complex networks is under-researched, and little has been written concerning leadership of translational research networks (TRNs) that take discoveries made 'at the bench' and translate them into practices used 'at the bedside.' Understanding leaders' opportunities and behaviours within TRNs working to solve this key problem in implementing evidence into clinical practice is therefore important. This study explored the network position of governing body members and perceptions of their role in a new TRN in Sydney, Australia. The paper asks three questions: Firstly, do the formal, mandated leaders of this TRN hold key positions of centrality or brokerage in the informal social network of collaborative ties? Secondly, if so, do they recognise the leadership opportunities that their network positions afford them? Thirdly, what activities associated with these key roles do they believe will maximise the TRN's success? Semi-structured interviews of all 14 governing body members conducted in early 2012 explored perceptions of their roles and sought comments on a list of activities drawn from review of successful transdisciplinary collaboratives combined with central and brokerage roles. An on-line, whole network survey of all 68 TRN members sought to understand and map existing collaborative connections. Leaders' positions in the network were assessed using UCInet, and graphs were generated in NetDraw. Social network analysis identified that governing body members had high centrality and high brokerage potential in the informal network of work-related ties. Interviews showed perceived challenges including 'silos' and the mismatch between academic and clinical goals of research. Governing body members recognised their central positions, which would facilitate the leadership roles of leading, making decisions, and providing expert advice necessary for the co-ordination of effort and relevant input across domains. Brokerage potential was recognised

    Transcatheter arterial chemoembolization (TACE) is a well-recognized procedure for management of hepatocellular carcinoma. We present a 54-year-old man who presented with a periumbilical maculopapular skin rash that developed after an otherwise uneventful TACE procedure. A retrospective review of imaging was consistent with non-target embolization of the hepatic falciform artery (HFA). He was treated with oral non-steroidal antiinflammatory medication for 3 weeks with improvement, but had slight skin induration and an excoriated papule at 6-month follow-up. Non-target embolization of HFA is very rare, but clinicians and interventionalists should be aware of this complication, especially in patients predisposed to enlargement of HFA.

    2016-01-01

    Chikungunya fever (CHIK-F) has been increasingly documented among Western travelers returning from areas with chikungunya virus transmission, which are also popular tourist sites. We present three Israeli travelers who developed fever, maculopapular rash and long-standing arthralgias while visiting northern Indian states not known to be involved in the chikungunya fever epidemic. We also present an epidemiological review of the chikungunya epidemic over the past decades. Rare systemic manifestations of this disorder, like catastrophic antiphospholipid syndrome (CAPS) and adult-onset Still's syndrome, are discussed. The present era of international travel poses a new diagnostic and epidemiologic challenge that demands increased awareness to the possibility of an exotic tropical infectious disease.

    Eight years of octopus fishery records from southwest Madagascar reveal significant positive impacts from 36 periodic closures on: (a) fishery catches and (b) village fishery income, such that (c) economic benefits from increased landings outweigh costs of foregone catch. Closures covered ~20% of a village's fished area and lasted 2-7 months. Octopus landings and catch per unit effort (CPUE) significantly increased in the 30 days following a closure's reopening, relative to the 30 days before a closure (landings: +718%, pfishing at that site (27/36 show positive net earnings; mean +$305/closure; mean +57.7% monthly). Benefits accrued faster than local fishers' time preferences during 17-27 of the 36 closures. High reported rates of illegal fishing during closures correlated with poor economic performance. We discuss the implications of our findings for broader co-management arrangements, particularly for catalyzing more comprehensive management.

    Full Text Available Microbial activities are widely exploited in the manufacture of valuable products. However, the many beneficial uses of microorganisms are often overshadowed by negative associations with disease and decay. This article describes an interactive activity aimed at school-aged children and members of the public, which introduces the concept of microbial enzymes and ultimately illustrates how the industrial uses of microbes have a positive impact on everyday life. Participants are guided through a simple chemical assay which allows them to use a hands-on approach to reveal bacterial enzymes at work. This activity is safe and economical to run and is suitable for use in both the classroom and external learning environments. Also included are supplemental educational resources to support the demonstration and suggestions for extensions to the activity described, which enable further exploration of the topic. This activity has been tested by more than 2000 people at public engagement events and has received much positive feedback.

    Skin and joint manifestations are part of the clinical spectrum of many disorders. Well-known associations include psoriatic arthritis and arthritis associated with autoimmune connective tissue diseases. This review focuses on less common associations where skin lesions can provide easily accessible and valuable diagnostic clues, and directly lead to the specific diagnosis or limit the list of possibilities. This may also affect health care resources as diagnostic tests are often low-specific, highly expensive and poorly available. This group of diseases can be divided into two subsets, based on the presence/absence of fever, and then further classified according to elementary skin lesions (macular, urticarial, maculo-papular, vesico-bullous, pustular, petechial and nodular). In most instances joint involvement occurs as peripheral migrating polyarthritis. Erythematosus macular or urticarial rashes occur in most febrile disorders such as monogenic autoinflammatory syndromes, Schnitzler's syndrome, Still's disease and rheumatic fever and afebrile diseases as urticarial vasculitis. Pustular rash may be observed in chronic recurrent multifocal osteomyelitis (CRMO) and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA) syndrome (both febrile) as well as in Behcet's disease and Synovitis, acne, pustulosis, hyperostosis and osteitis syndrome (both non-febrile). Papular lesions are typical of secondary syphilis, sarcoidosis, interstitial granulomatous dermatitis, papular petechial of cutaneous small-vessel vasculitis and nodular lesions of polyarteritis nodosa and multicentric reticulohistiocytosis all of which are afebrile. Differential diagnosis includes infections and drug reactions which may mimic several of these conditions. To biopsy the right skin lesion at the right time it is essential to obtain relevant histological information.

  12. Rash with DERMABOND PRINEO Skin Closure System Use in Bilateral Reduction Mammoplasty: A Case Series

    Directory of Open Access Journals (Sweden)

    R. W. Knackstedt

    2015-01-01

    Full Text Available Background. Bilateral reduction mammoplasty is a common plastic surgery procedure that can be complicated by unfavorable scar formation along incision sites. Surgical adhesives can be utilized as an alternative or as an adjunct to conventional suture closures to help achieve good wound tension and provide an adequate barrier with excellent cosmesis. The recently introduced DERMABOND PRINEO Skin Closure System Skin Closure System combines the skin adhesive 2-octyl cyanoacrylate with a self-adhering polyester-based mesh. Proposed benefits of wound closure with DERMABOND PRINEO Skin Closure System, used with or without sutures, include its watertight seal, easy removal, microbial barrier, even distribution of tension, and reduction in wound closure time. Although allergic reactions to 2-octyl cyanoacrylate have been reported, few allergic reactions to DERMABOND PRINEO Skin Closure System have been noted in the literature. This case series describes three patients who experienced an allergic reaction to DERMABOND PRINEO Skin Closure System after undergoing elective bilateral reduction mammoplasties at our institution to further explore this topic. Methods. Retrospective chart review of bilateral reduction mammoplasty patients who received DERMABOND PRINEO Skin Closure System dressing at our institution was performed. Results. Three patients were identified as having a rash in reaction to DERMABOND PRINEO Skin Closure System after bilateral reduction mammoplasty. All three patients required systemic steroid treatment to resolve the rash. One patient was identified as having a prior adhesive reaction. Conclusions. DERMABOND PRINEO Skin Closure System has demonstrated its efficacy in optimizing scar healing and appearance. However, as we demonstrate these three allergic reactions to DERMABOND PRINEO Skin Closure System, caution must be utilized in its usage, namely, in patients with a prior adhesive allergy and in sites where moisture or friction may

  13. Positive Allosteric Modulation of Kv Channels by Sevoflurane: Insights into the Structural Basis of Inhaled Anesthetic Action.

    Directory of Open Access Journals (Sweden)

    Qiansheng Liang

    Full Text Available Inhalational general anesthesia results from the poorly understood interactions of haloethers with multiple protein targets, which prominently includes ion channels in the nervous system. Previously, we reported that the commonly used inhaled anesthetic sevoflurane potentiates the activity of voltage-gated K+ (Kv channels, specifically, several mammalian Kv1 channels and the Drosophila K-Shaw2 channel. Also, previous work suggested that the S4-S5 linker of K-Shaw2 plays a role in the inhibition of this Kv channel by n-alcohols and inhaled anesthetics. Here, we hypothesized that the S4-S5 linker is also a determinant of the potentiation of Kv1.2 and K-Shaw2 by sevoflurane. Following functional expression of these Kv channels in Xenopus oocytes, we found that converse mutations in Kv1.2 (G329T and K-Shaw2 (T330G dramatically enhance and inhibit the potentiation of the corresponding conductances by sevoflurane, respectively. Additionally, Kv1.2-G329T impairs voltage-dependent gating, which suggests that Kv1.2 modulation by sevoflurane is tied to gating in a state-dependent manner. Toward creating a minimal Kv1.2 structural model displaying the putative sevoflurane binding sites, we also found that the positive modulations of Kv1.2 and Kv1.2-G329T by sevoflurane and other general anesthetics are T1-independent. In contrast, the positive sevoflurane modulation of K-Shaw2 is T1-dependent. In silico docking and molecular dynamics-based free-energy calculations suggest that sevoflurane occupies distinct sites near the S4-S5 linker, the pore domain and around the external selectivity filter. We conclude that the positive allosteric modulation of the Kv channels by sevoflurane involves separable processes and multiple sites within regions intimately involved in channel gating.

  15. Effect of width, amplitude, and position of a core mantle boundary hot spot on core convection and dynamo action

    Dietrich, Wieland; Hori, Kumiko

    2015-01-01

    Within the fluid iron cores of terrestrial planets, convection and the resulting generation of global magnetic fields are controlled by the overlying rocky mantle. The thermal structure of the lower mantle determines how much heat is allowed to escape the core. Hot lower mantle features, such as the thermal footprint of a giant impact or hot mantle plumes, will locally reduce the heat flux through the core mantle boundary (CMB), thereby weakening core convection and affecting the magnetic field generation process. In this study, we numerically investigate how parametrised hot spots at the CMB with arbitrary sizes, amplitudes, and positions affect core convection and hence the dynamo. The effect of the heat flux anomaly is quantified by changes in global flow symmetry properties, such as the emergence of equatorial antisymmetric, axisymmetric (EAA) zonal flows. For purely hydrodynamic models, the EAA symmetry scales almost linearly with the CMB amplitude and size, whereas self-consistent dynamo simulations typ...

    2002-08-01

    We have demonstrated the utility of a 9-week in vivo two-stage assay for lung cancer initiating agents, using transgenic mice carrying the human prototype c-Ha-ras gene (rasH2 mice) and butylhydroxytoluene (BHT) as a potent lung promoter (rasH2/BHT model). In the present study, to ascertain appropriate conditions for BHT administration in this model, the effects of exposure on proliferation of alveolar type II cells in male rasH2 mice were examined. Additionally, use of BHT was validated for promotion of urethane (UR) carcinogenesis in male and female rasH2 mice. In a time-course study of a single intragastric administration of BHT at a dose of 400 mg/kg, increased bromodeoxyuridine-labeling index (LI) reached a maximum 3 days after treatment and was still observed after 7 days. In a dose-response study, effects were dose-dependent, the dose of 400 mg/kg causing eight-fold elevation as compared to the control. With repeated administration, whereas the LI was increased dramatically at first, effects gradually diminished with further exposure, and finally six BHT treatments failed to induce cell proliferation. In a two-stage model using UR as the initiator, although up to five consecutive doses of BHT were able to exert continued enhancing effects in terms of adenoma yield, no increment was evident with further treatments. The data overall indicate that a rasH2/BHT model with five weekly administrations of BHT at a dose of 400 mg/kg is most efficacious.

    2013-03-15

    A probable case of drug reaction with eosinophilia and systemic symptoms (DRESS) associated with consecutive use of three medications for seizure control is reported. A 36-year-old woman was treated at a community hospital for a mild fever (37.9°C) and diffuse raised maculopapular rash with erythema. Three weeks previously, she had been diagnosed with a seizure disorder and initiated on phenytoin (dose unknown) at that time; about two weeks later, she developed a rash, prompting a switch from phenytoin to extended-release divalproex sodium 250 mg orally twice daily. During the week after discontinuation of phenytoin, the rash was improving, but about five days after the initiation of divalproex therapy, she had worsening rash and pruritus requiring urgent treatment; the divalproex was discontinued, and phenobarbital 30 mg three times daily was initiated for continued seizure control. Despite the discontinuation of phenytoin and divalproex, the patient's hepatic function worsened over five days, and phenobarbital therapy was discontinued. With continued deterioration of the patient's condition to fulminant hepatic failure, a transfer to a liver transplant facility was arranged. The use of the adverse reaction probability scale of Naranjo et al. in this case yielded a score of 8, indicating a probable relationship between DRESS and the serial use of phenytoin, divalproex, and phenobarbital. After receiving phenytoin for treatment of seizure disorder, a 36-year-old woman developed a fever and maculopapular rash with erythema. This reaction continued even after drug therapy was switched to extended-release divalproex and then phenobarbital. The patient's liver function deteriorated despite discontinuation of all seizure medications.

    This study aimed to translate movement patterns, technical skills and tactical actions associated with high-intensity efforts into metrics that could potentially be used to construct position-specific conditioning drills. A total of 20 individual English Premier League players' high-intensity running profiles were observed multiple times (n = 100) using a computerised tracking system. Data were analysed using a novel high-intensity movement programme across five positions (centre back [CB], full-back [FB], central midfielder [CM], wide midfielder [WM] and centre forward [CF]). High-intensity efforts in contact with the ball and the average speed of efforts were greater in WMs than CBs, CMs and CFs (effect sizes [ES]: 0.9-2.1, P WMs produced more repeated efforts than CBs and CMs (ES: 0.6-1.3, P WMs executed more tricks post effort than CBs and CMs (ES: 1.2-1.3, P WMs performed more crosses post effort than other positions (ES: 1.1-2.0, P WMs (ES: 0.9-1.4, P WMs (ES: 0.9-1.1, P < 0.01). The data demonstrate unique high-intensity trends in and out of possession that could assist practitioners when devising position-specific drills.

    Full Text Available Tyrosine kinase inhibitors (TKIs are a pharmaceutical class of small molecules, orally available with manageable safety profile, approved worldwide for the treatment of several neoplasms, including lung, breast, kidney and pancreatic cancer as well as gastro-intestinal stromal tumours and chronic myeloid leukaemia. In recent years, management of lung cancer has been moving towards molecular-guided treatment, and the best example of this new approach is the use of the tyrosine kinase inhibitors (TKIs in patients with mutations in the epidermal growth factor receptor (EGFR. The identification of molecular predictors of response can allow the selection of patients who will be the most likely to respond to these tyrosine kinase inhibitors (TKIs. Gastrointestinal (GI adverse events (AEs are frequently observed in patients receiving EGFR tyrosine kinase inhibitor therapy and are most impactful on the patient's quality of life. Dermatologic side effects are also relatively common among patients treated with EGFR inhibitors. Evidence has emerged in recent years to suggest that the incidence and severity of rash, positively correlated with response to treatment.These skin disorders are generally mild or moderate in severity and can be managed by appropriate interventions or by reducing or interrupting the dose. Appropriate and timely management make it possible to continue a patient's quality of life and maintain compliance; however if these adverse events (AEs are not managed appropriately, and become more severe, treatment cessation may be warranted compromising clinical outcome. Strategies to improve the assessment and management of TKI related skin AEs are therefore essential to ensure compliance with TKI therapy, thereby enabling patients to achieve optimal benefits. This article provides a consensus on practical recommendation for the prevention and management of diarrhoea and rash in Non-Small Cell Lung Cancer (NSCLC patients receiving TKIs.

    Lyme disease, the most commonly reported vector-borne disease in the United States, results from infection with Borrelia burgdorferi. Early clinical diagnosis of this disease is largely based on the presence of an erythematous skin lesion for individuals in high-risk regions. This, however, can be confused with other illnesses including southern tick-associated rash illness (STARI), an illness that lacks a defined etiological agent or laboratory diagnostic test, and is coprevalent with Lyme disease in portions of the eastern United States. By applying an unbiased metabolomics approach with sera retrospectively obtained from well-characterized patients, we defined biochemical and diagnostic differences between early Lyme disease and STARI. Specifically, a metabolic biosignature consisting of 261 molecular features (MFs) revealed that altered N-acyl ethanolamine and primary fatty acid amide metabolism discriminated early Lyme disease from STARI. Development of classification models with the 261-MF biosignature and testing against validation samples differentiated early Lyme disease from STARI with an accuracy of 85 to 98%. These findings revealed metabolic dissimilarity between early Lyme disease and STARI, and provide a powerful and new approach to inform patient management by objectively distinguishing early Lyme disease from an illness with nearly identical symptoms.

    Full Text Available A clinical and laboratory evaluation of 11 children and young adults with measleslike rash was done during the measles outbreak in the Greater São Paulo Metropolitan area at the end of 1996 and spread over the country during 1997. Measles was laboratory confirmed in 07 patients by specific IgM detection in acute serum specimens using an IgM-capture EIA, by specific IgG seroconversion in serum pairs, and by reverse transcription PCR and virus isolation in peripheral blood lymphocytes. Clinical presentations were not always classic; one of the 07 cases had received measles vaccine and corresponded to modified clinical case of measles. The 4 remaining cases were negative for measles and were diagnosed as exanthem subitum (2 cases, scarlet fever and Kawasaki disease. The present study reinforces the view that clinical features alone are not sufficient for establishing an accurate diagnosis in the post-vaccine era, and a surveillance system based on sensitive laboratory results is needed so that it can confirm IgM-negative measles cases.

    Blau syndrome (MIM 186580), first described in a large, three-generation kindred, is an autosomal, dominantly inherited disease characterized by multiorgan, tissue-specific inflammation. Its clinical phenotype includes granulomatous arthritis, skin rash, and uveitis and probably represents a subtype of a group of clinical entities referred to as {open_quotes}familial granulomatosis.{close_quotes} It is the sole human model with recognizably Mendelian inheritance for a variety of multisystem inflammatory diseases affecting a significant percentage of the population. A genomewide search for the Blau susceptibility locus was undertaken after karyotypic analysis revealed no abnormalities. Sixty-two of the 74-member pedigree were genotyped with dinucleotide-repeat markers. Linkage analysis was performed under dominant model of inheritance with reduced penetrance. The marker D16S298 gave a maximum LOD score of 3.75 at {theta} = .04, with two-point analysis. LOD scores for flanking markers were consistent and placed the Blau susceptibility locus within the 16p12-q21 interval. 46 refs., 3 figs., 3 tabs.

    We present a case report of 46-year-old man with no medical history, who complained of extreme fatigue, near-syncope, and palpitations. He initially presented in complete heart block. A transvenous pacemaker was placed in the emergency department, and he was started empirically on Ceftriaxone for Lyme disease. He was admitted and over the course of the next few days, his rhythm regressed to Mobitz type I first-degree atrioventricular block and then to normal sinus rhythm. This case report highlights some important features regarding Lyme carditis, a rare presentation of early disseminated Lyme disease (seen in a few weeks to months after the initial tick bite). In 25%-30% of patients, the characteristic targetoid rash may not be seen, a likely culprit of the disease not being detected early and progressing to disseminated disease. The most common cardiac complaint of Lyme disease is palpitations, occurring in 6.6% of patients, which may not accurately reflect progression into disseminated Lyme disease because it is a nonspecific finding. Conduction abnormality, occurring in 1.8% of patients, is a more specific finding of Borrelia invading cardiac tissue. Finally, this case report highlights a recommendation that patients with confirmed Lyme disease or those presenting with cardiac abnormalities or symptoms who have an atypical profile for a cardiac event should be screened with a 12-lead electrocardiogram, Lyme serology, and be considered for antibiotic therapy with the possibility of temporary pacing.

    2000-02-01

    Blau syndrome (familial granulomatous arthritis, iritis, and rash) was originally described in 1985, in 11 members of a family of Dutch ancestry. Inheritance is autosomal dominant. Several more Caucasian families have been described since. Skin and synovial biopsy specimens show noncaseating sarcoid like granulomas, but the lung is not involved as in classic sarcoidosis. This report describes 3 members of an African American family with Blau syndrome. It is important to differentiate this genetic disorder from other childhood arthritides, such as, juvenile rheumatoid arthritis, juvenile spondyloarthropathies, and early-onset sarcoidosis, because of the need for genetic counseling, treatment and differing potential for selective involvement of other organs (eye, skin, and tendons/joints). All children of an affected individual have a 50% chance of inheriting the disease. Unaffected children do not have to be concerned about subsequent generations being affected. The response to conventional treatments used in juvenile rheumatoid arthritis and to etanercept in our patients has not been satisfactory. Joint disease responds to corticosteroids, but these agents are not suitable for a disease that is lifelong. The eye involvement is aggressive and can lead to blindness. These patients need close follow-up by an ophthalmologist.

    Full Text Available Nakajo-Nishimura syndrome (ORPHA2615; also registered as Nakajo syndrome in OMIM#256040 is a distinct inherited inflammatory and wasting disease, originally reported from Japan. This disease usually begins in early infancy with a pernio-like rash, especially in winter. The patients develop periodic high fever and nodular erythema-like eruptions, and gradually progress lipomuscular atrophy in the upper body, mainly the face and the upper extremities, to show the characteristic thin facial appearance and long clubbed fingers with joint contractures. So far about 30 cases have been reported from Kansai, especially Wakayama and Osaka, Tohoku and Kanto areas. At present, about 10 cases are confirmed to be alive only in the Kansai area, including one infant case in Wakayama. However, more cases are expected to be added in the near future. Although cause of the disease has long been undefined, a homozygous mutation of the PSMB8 gene, which encodes the β35i subunit of immunoproteasome, has been identified to be responsible in 2011. By analyses of the patients-derived cells and tissues, it has been suggested that accumulation of ubiquitinated and oxidated proteins due to immunoproteasome dysfunction causes hyperactivation of p38 mitogen-activated protein kinase and interleukin-6 overproduction. Since similar diseases with PSMB8 mutations have recently been reported from Europe and the United States, it is becoming clear that Nakajo-Nishimura syndrome and related disorders form proteasome disability syndromes, a new category of autoinflammatory diseases distributed globally.

    Behavioral trajectories during middle childhood are predictive of consequential outcomes later in life (e.g., substance abuse, violence). Social and emotional learning (SEL) programs are designed to promote trajectories that reflect both growth in positive behaviors and inhibited development of negative behaviors. The current study used growth mixture models to examine effects of the Positive Action (PA) program on behavioral trajectories of social-emotional and character development (SECD) and misconduct using data from a cluster-randomized trial that involved 14 schools and a sample of predominately low-income, urban youth followed from 3rd through 8th grade. For SECD, findings indicated that PA was similarly effective at improving trajectories within latent classes characterized as "high/declining" and "low/stable". Favorable program effects were likewise evident to a comparable degree for misconduct across observed latent classes that reflected "low/rising" and "high/rising" trajectories. These findings suggest that PA and perhaps other school-based universal SEL programs have the potential to yield comparable benefits across subgroups of youth with differing trajectories of positive and negative behaviors, making them promising strategies for achieving the intended goal of school-wide improvements in student outcomes.

  10. 4-Aminopyridine induces positive lusitropic effects and prevents the negative inotropic action of phenylephrine in the rat cardiac tissue subjected to ischaemia.

    The effects of 4-aminopyridine (4-AP) at concentration of 1 mM on the contractility of rat isolated papillary muscle subjected to simulated ischaemia has been evaluated. Additionally, the effects of 4-AP on the phenylephrine inotropic action (a selective agonist of alpha1-adrenergic receptor) on rat isolated cardiac tissue underwent simulated ischaemia and reperfusion was studied. Experiments were performed on rat isolated papillary muscles obtained from left ventricle. The following parameters have been measured: force of contraction (Fc), velocity of contraction (+dF/dt), velocity of relaxation (-dF/dt) and the ratio between time to peak contraction (ttp) and relaxation time at the level of 10% of total contraction amplitude (tt10) as an index of lusitropic effects. Simulated ischaemia lasting 45 min was induced by replacement of standard normoxic solution by no-substrat one gassing with 95% N2/5%CO2. Although 4-AP exerted a slight, but significant positive inotropic action itself, pretreatment with 1 mM of this compound significantly depressed a recovery of Fc and +dF/dt, but improves recovery of -dF/dt in the rat papillary muscle during reperfusion as compared with control group of preparations. Moreover, the paradoxical negative inotropic action of phenylephrine observed in rat stunned papillary muscle was prevented in preparations previously treated by 4-AP. These findings suggest that an inhibition of outward K+ current (probably transient outward and rapid component of delayed rectifying currents at 1 mM of 4-AP) aggravates ischaemia-induced failure in contractility but prevents changes in alpha1-adrenergic receptor signaling pathway occuring during ischaemia.

Patients receiving cetuximab 500 mg/m(2) every second week plus chemotherapy for metastatic cancer were included. In each patient, vitamin K3 cream...... stained for EGFR and pEGFR. RESULTS: Application of vitamin K3 cream twice daily during treatment with cetuximab did not reduce the number of papulopustular eruptions, and this was independent of the use of systemic tetracycline. No significant changes in the staining of EGFR or pEGFR were observed...... in the skin of the vitamin K3-treated area compared to the placebo area. CONCLUSION: The present data do not support any clinical or immunohistochemical benefit of using vitamin K3 cream for cetuximab-induced rash....

  13. Itch and skin rash from chocolate during fluoxetine and sertraline treatment: Case report

    2004-11-01

    Full Text Available Abstract Background The skin contains a system for producing serotonin as well as serotonin receptors. Serotonin can also cause pruritus when injected into the skin. SSRI-drugs increase serotonin concentrations and are known to have pruritus and other dermal side effects. Case presentation A 46-year-old man consulted his doctor due to symptoms of depression. He did not suffer from any allergy but drinking red wine caused vasomotor rhinitis. Antidepressive treatment with fluoxetine 20 mg daily was initiated which was successful. After three weeks of treatment an itching rash appeared. An adverse drug reaction (ADR induced by fluoxetine was suspected and fluoxetine treatment was discontinued. The symptoms disappeared with clemastine and betametasone treatment. Since the depressive symptoms returned sertraline medication was initiated. After approximately two weeks of sertraline treatment he noted an intense itching sensation in his scalp after eating a piece of chocolate cake. The itch spread to the arms, abdomen and legs and the patient treated himself with clemastine and the itch disappeared. He now realised that he had eaten a chocolate cake before this episode and remembered that before the first episode he had had a chocolate mousse dessert. He had never had any reaction from eating chocolate before and therefore reported this observation to his doctor. Conclusions This case report suggests that there may be individuals that are very sensitive to increases in serotonin concentrations. Dermal side reactions to SSRI-drugs in these patients may be due to high activity in the serotonergic system at the dermal and epidermo-dermal junctional area rather than a hypersensitivity to the drug molecule itself.

    The purpose of this descriptive correlational study was to examine practicing nurses' attitudes, subjective norms, and intentions to care for HIV positive patients, using the Theory of Reasoned Action. One hundred and forty-one subjects completed a questionnaire developed according to guidelines described by Ajzen and Fishbein (1980). Consistent with the theory, nurses' attitudes and subjective norms were found to be significant predictors of intentions to care for persons who are HIV positive (R2 = 0.27). Personal beliefs found to discriminate between intenders and nonintenders were those related to possible consequences for self, family, and friends, but not job-related consequences. Normative beliefs which discriminated between groups were also related to nonprofessional referents' expectations. In addition, qualitative data showed persistent concerns about occupational risk for contracting AIDS. Based on the results of this research, it is recommended that nurse educators in both clinical and academic settings, target specific educational/training interventions to include transmission, prevention, as well as exploration of feelings, attitudes, beliefs, and behavioral intentions about HIV-related topics. Further theory-based research and testing of interventions to change practicing nurses' attitudes and beliefs about HIV disease are advocated.

    Full Text Available Antimicrobial peptides (AMPs have been proposed as a novel class of antimicrobials that could aid the fight against antibiotic resistant bacteria. The mode of action of AMPs as acting on the bacterial cytoplasmic membrane has often been presented as an enigma and there are doubts whether the membrane is the sole target of AMPs. Progress has been made in clarifying the possible targets of these peptides, which is reported in this review with as focus gram-positive vegetative cells and spores. Numerical estimates are discussed to evaluate the possibility that targets, other than the membrane, could play a role in susceptibility to AMPs. Concerns about possible resistance that bacteria might develop to AMPs are addressed. Proteomics, transcriptomics and other molecular techniques are reviewed in the context of explaining the response of bacteria to the presence of AMPs and to predict what resistance strategies might be. Emergent mechanisms are cell envelope stress responses as well as enzymes able to degrade and/or specifically bind (and thus inactivate AMPs. Further studies are needed to address the broadness of the AMP resistance and stress responses observed.

    Evaluating programs targeting physical activity may help to reduce disparate rates of obesity among African Americans. We report formative process evaluation methods and implementation dose, fidelity, and reach in the Positive Action for Today's Health trial. We applied evaluation methods based on an ecological framework in 2 community-based police-patrolled walking programs targeting access and safety in underserved African American communities. One program also targeted social connectedness and motivation to walk using a social marketing approach. Process data were systematically collected from baseline to 12 months. Adequate implementation dose was achieved, with fidelity achieved but less stable in both programs. Monthly walkers increased to 424 in the walking-plus-social marketing program, indicating expanding program reach, in contrast to no increase in the walking-only program. Increased reach was correlated with peer-led Pride Strides (r = .92; P social marketing component, and program social interaction was the primary reason for which walkers reported participating. Formative process evaluation demonstrated that the walking programs were effectively implemented and that social marketing increased walking and perceived social connectedness in African American communities.

    2015-12-01

    Preparing for positive aging is shaped by the social context a person lives in. The present qualitative study explores and compares representations about preparatory actions in precarious workers (i.e., with temporary job contracts and insecure pension plans) and individuals with secure pension plans living in Germany. It also examines, the discrepancy between what middle-aged persons think they should be doing in preparation and what they report doing for aging well. Findings from the analysis of the semi-structured interviews conducted here show that people who have insecure pension plans tend to see themselves as social networkers and optimists, while those with secure pension plans see themselves as social activists and careful planners of old age. All participants value an active, healthy body but manage to do little in order to attain it due to lacking time and discipline. In accordance with the socioemotional selectivity theory, perceiving a short-time perspective makes precarious individuals focus on emotional goals, while financially secure individuals value social goals. Implications for practice and policy change are discussed.

    Skin rash associated with specific antiepileptic drugs occurs not infrequently and it usually necessitates discontinuation of the causative drugs. An alternative strategy is to desensitize the individual to the offending drug. We checked the human leukocyte antigen genotypes and conducted a pilot study to investigate the usefulness and safety of desensitization in pediatric patients with skin rash associated with oxcarbazepine. We enrolled 19 patients with epilepsy who had discontinued oxcarbazepine because of skin rash despite an initial good response and then became refractory to other antiepileptic drugs along with an individual with paroxysmal kinesigenic dyskinesia with a similar situation. High-resolution HLA-A and -B genotyping was performed to investigate the genetic risk. The desensitization began with 0.1 mg daily reaching 120 mg on the thirty-first day. Thereafter, the dose was increased at a rate of 12 mg/day. Nineteen patients completed the desensitization protocol to a target dosage over 2-5 months. Five patients developed itching and erythema during desensitization, but the symptoms disappeared after withholding a dose increment transiently. There were no human leukocyte antigen genotypes relevant to aromatic antiepileptic drug-induced severe hypersensitivity reactions. The seizure frequency was reduced to less than at baseline in 18 individuals. This study demonstrated 95% efficacy, including 42% seizure-free patients and the favorable tolerability of desensitization to oxcarbazepine in patients with intractable epilepsy and one patient with paroxysmal kinesigenic dyskinesia. Screening for sensitive human leukocyte antigen types and exclusion of severe hypersensitivity reactions should precede desensitization. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Neisseria lactamica, a commensal, has been very rarely reported to cause diseases in immunocompromised hosts. In medical literature, there is only one report of a cavitatory lung lesion caused by it. The patient was a kidney transplant recipient. Neisseria lactamica was found to be the cause of his pulmonary cavity and a desquamating rash on feet. With the rapidly spreading medical advance, more and more patients are getting organ transplants, so the population of immunocompromised people is on the rise. We expect more sinister and less expected organisms to cause diseases in patients who have organ transplants.

It often affects liver function, but it can also affect kidney, lungs, and heart. Severe gastrointestinal involvement is rare. We present a case of a 31-year-old hispanic woman with pseudomembranous colitis associated with lamotrigine-induced DRESS syndrome. To the best of our knowledge, this is the fourth reported case of severe involvement of the gastrointestinal tract and the first to report pseudomembranous colitis in the setting of DRESS syndrome.

    positionings emerges based on empirical examples of research in parent–children consumption. Positionings are flexible discursive fixations of the relationship between the performances of the practitioner, other practitioners, media discourse and consumption activities. The basic positioning types...... are the practice maintenance and the practice change position, with different sorts of adapting in between. Media discourse can become a resource for a resistant position against social control or for an appropriating position in favour of space for action. Regardless of the current relation to a particular media...... discourse, practitioners attempt to maintain their self-positioning of competence when performing. This leads us, as researchers, to caution against any a priori anticipation of the anchoring power of media discourses within everyday activities....

    Skin rash is an adverse event which might be associated with longer survival in patients treated with epidermal growth factor receptor tyrosine kinase inhibitors. The aim of this nonrandomised phase II clinical trial is to prospectively evaluate the relationship between skin rash and overall survival (OS) in advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine. Patients were given gemcitabine (1000 mg/m2/week, 3 weeks every 4 weeks) plus erlotinib (100 mg/day orally continuously) until disease progression/unacceptable toxicity. The primary end point was OS. A total of 153 eligible patients were enrolled (grade≥2 rash, 25%; grade<2 rash, 75%). OS was longer in patients with grade≥2 rash versus grade<2 (11 versus 5 months; P<0.001). Progression-free survival was longer in patients with grade≥2 rash versus grade<2 (6 versus 3 months; P<0.001) and shorter in those without rash versus grade 1 (2 versus 4 months; P=0.005) or grade≥2 (2 versus 6 months; P<0.001). Patients with grade≥2 rash showed higher rates of overall response (21% versus 7%; P<0.05) and disease control (84% versus 43%; P<0.05) versus grade<2. This study prospectively confirms the relationship between rash and longer OS in unresectable locally advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine.

    2015-04-01

    Understanding the mental life of persons with psychosis/schizophrenia has been the crucial challenge of psychiatry since its origins, both for scientific models as well as for every therapeutic encounter between persons with and without psychosis/schizophrenia. Nonetheless, a preliminary understanding is always the first step of phenomenological as well as other qualitative research methods addressing persons with psychotic experiences in their life-world. In contrast to Rashed's assertions, in order to achieve such understanding, phenomenological psychopathologists need not necessarily adopt the transcendental-phenomenological attitude, which, however, is often required if performing phenomenological philosophy. Additionally, in the course of these (non-philosophical) scientific endeavors, differences between persons with psychosis/schizophrenia and so-called normal people seem to have a methodological function and value driving the scientist in her enterprise.

    2015-01-01

    Full Text Available Cellulitis in the setting of lymphedema is an uncommon but clinically important presentation to the emergency department. Stagnant lymph is an ideal medium for bacterial growth and progression can be rapid due to decreased ability to fight infection in the affected area. Infections are commonly caused by gram-positive cocci, though blood cultures are often negative. Treatment should be aimed at rapid initiation of antibiotics targeting these species. There may be a role for antibiotic prophylaxis in recurrent cases.

    Cutaneous lupus erythematosus (CLE) may have prognostic implications for systemic lupus erythematosus (SLE). We aimed to determine the impact of discoid lupus erythematosus (DLE) and malar rash on SLE disease activity. Data were analyzed from the Toronto Lupus Clinic prospective cohort study. We compared SLE patients with active DLE or malar rash at SLE diagnosis to SLE patients who never developed CLE. Outcomes were assessed at one and five years, including Adjusted Mean Systemic Lupus Erythematosus Disease Activity Index 2000 (AMS). A total of 524 SLE patients (284 without CLE, 65 with DLE, and 175 with malar rash) were included. Mean AMS scores in patients without CLE at one and five years were 5.96 ± 5.06 and 4.00 ± 3.52, which did not differ significantly from scores at one (6.93 ± 5.31, p = 0.17) and five years (4.29 ± 2.62, p = 0.63) in the DLE group. In patients with malar rash, AMS scores at one (8.30 ± 6.80, p systemic disease over time, while DLE has no significant impact on general SLE disease activity. © The Author(s) 2015.

    2014-08-01

    Full Text Available Background: Pityriasis rosea is an acute disseminated rash of unknown etiology and prolonged duration, characterized by erythematous- squamous plaques. Despite having an ostentatious clinical picture for both the patient and family, it is self-limited and usually resolves without sequelae. Pityriasis rosea is often erroneously diagnosed as mycosis and given unnecessary treatment. Objective: To describe the clinical and demographical features of pity- riasis rosea in a group of Mexican pediatric patients. Patients and methods: Retrospective and descriptive study in which the clinical and demographic features of patients attended at the department of dermatology of the National Institute of Pediatrics with diagnosis of pityriasis rosea within a ten year period were analysed. Results: Thirty patients with pityriasis rosea, with a frequency of 3.6 per 1000 dermatological patients. Pityriasis rosea was more frequent in females with a ratio of 1.5 to 1 and a mean age of 10 years. More than half of the patients (56% had an atypical presentation, and biopsy was mandatory in 7 patients to establish the final diagnosis. Conclusions: The knowledge of the clinical features of pityriasis rosea by primary care physicians will prevent from unnecessary work-up and treatments.

    The Kata-Rash arc fragment is an allochthonous thrust-bound body situated near Penjween, 100 km northeast of Sulymannia city, Kurdistan Region, within the Iraqi portion of the Zagros suture zone. It forms part of the suprasubduction zone 'Upper Allochthon' terranes (designated as the Gimo-Qandil Group), which is dominated by calc-alkaline andesite and basaltic-andesite, rhyodacite to rhyolite, crosscut by granitic, granodioritic, and dioritic dykes. Previously, rocks of the Kata-Rash arc fragment were interpreted as a part of the Eocene Walash volcanic group. However, SHRIMP zircon U-Pb dates on them of 108.1 ± 2.9 Ma (Harbar volcanic rocks) and 107.7 ± 1.9 Ma (Aulan intrusion) indicate an Albian-Cenomanian age, which is interpreted as the time of igneous crystallisation. The Aulan intrusion zircons have initial εHf values of + 8.6 ± 0.2. On a Nb/Yb-Th/Yb diagram, all Kata-Rash samples fall within the compositional field of arc-related rocks, i.e. above the mid-ocean-ridge basalt (MORB)-ocean island basalt (OIB) mantle array. Primitive-mantle-normalised trace-element patterns for the Kata-Rash samples show enrichment in the large ion lithophile elements and depletion in the high-field-strength elements supporting their subduction-related character.

    2016-03-02

    To enhance physiological function of NMDA receptors (NMDARs), we identified positive allosteric modulators (PAMs) of NMDARs with selectivity for GluN2A subunit-containing receptors. X-ray crystallography revealed a binding site at the GluN1-GluN2A dimer interface of the extracellular ligand-binding domains (LBDs). Despite the similarity between the LBDs of NMDARs and AMPA receptors (AMPARs), GluN2A PAMs with good selectivity against AMPARs were identified. Potentiation was observed with recombinant triheteromeric GluN1/GluN2A/GluN2B NMDARs and with synaptically activated NMDARs in brain slices from wild-type (WT), but not GluN2A knockout (KO), mice. Individual GluN2A PAMs exhibited variable degrees of glutamate (Glu) dependence, impact on NMDAR Glu EC50, and slowing of channel deactivation. These distinct PAMs also exhibited differential impacts during synaptic plasticity induction. The identification of a new NMDAR modulatory site and characterization of GluN2A-selective PAMs provide powerful molecular tools to dissect NMDAR function and demonstrate the feasibility of a therapeutically desirable type of NMDAR enhancement.

  18. Action semantics modulate action prediction.

    Science.gov (United States)

    Springer, Anne; Prinz, Wolfgang

    2010-11-01

    Previous studies have demonstrated that action prediction involves an internal action simulation that runs time-locked to the real action. The present study replicates and extends these findings by indicating a real-time simulation process (Graf et al., 2007), which can be differentiated from a similarity-based evaluation of internal action representations. Moreover, results showed that action semantics modulate action prediction accuracy. The semantic effect was specified by the processing of action verbs and concrete nouns (Experiment 1) and, more specifically, by the dynamics described by action verbs (Experiment 2) and the speed described by the verbs (e.g., "to catch" vs. "to grasp" vs. "to stretch"; Experiment 3). These results propose a linkage between action simulation and action semantics as two yet unrelated domains, a view that coincides with a recent notion of a close link between motor processes and the understanding of action language.

  19. Simple technique for in field samples collection in the cases of skin rash illness and subsequent PCR detection of orthopoxviruses and varicella zoster virus.

    Directory of Open Access Journals (Sweden)

    Catherine Dumont

    Full Text Available BACKGROUND: In case of outbreak of rash illness in remote areas, clinically discriminating monkeypox (MPX from severe form of chickenpox and from smallpox remains a concern for first responders. OBJECTIVE: The goal of the study was therefore to use MPX and chickenpox outbreaks in Democratic Republic of Congo (DRC as a test case for establishing a rapid and specific diagnosis in affected remote areas. METHODS: In 2008 and 2009, successive outbreaks of presumed MPX skin rash were reported in Bena Tshiadi, Yangala and Ndesha healthcare districts of the West Kasai province (DRC. Specimens consisting of liquid vesicle dried on filter papers or crusted scabs from healing patients were sampled by first responders. A field analytical facility was deployed nearby in order to carry out a real-time PCR (qPCR assay using genus consensus primers, consensus orthopoxvirus (OPV and smallpox-specific probes spanning over the 14 kD fusion protein encoding gene. A PCR-restriction fragment length polymorphism was used on-site as backup method to confirm the presence of monkeypox virus (MPXV in samples. To complete the differential diagnosis of skin rash, chickenpox was tested in parallel using a commercial qPCR assay. In a post-deployment step, a MPXV-specific pyrosequencing was carried out on all biotinylated amplicons generated on-site in order to confirm the on-site results. RESULTS: Whereas MPXV proved to be the agent causing the rash illness outbreak in the Bena Tshiadi, VZV was the causative agent of the disease in Yangala and Ndesha districts. In addition, each on-site result was later confirmed by MPXV-specific pyrosequencing analysis without any discrepancy. CONCLUSION: This experience of rapid on-site dual use DNA-based differential diagnosis of rash illnesses demonstrates the potential of combining tests specifically identifying bioterrorism agents and agents causing natural outbreaks. This opens the way to rapid on-site DNA-based identification of a

    More than a decade ago, Edwin Taylor issued a "call to action" that presented the case for basing introductory university mechanics teaching around the principle of stationary action [E. F. Taylor, Am. J. Phys. 71, 423-425 (2003)]. We report on our response to that call in the form of an investigation of the teaching and learning of the stationary action formulation of physics in a first-year university course. Our action physics instruction proceeded from the many-paths approach to quantum physics to ray optics, classical mechanics, and relativity. Despite the challenges presented by action physics, students reported it to be accessible, interesting, motivational, and valuable.

    Full Text Available Complementary colors are color pairs which, when combined in the right proportions, produce white or black. Complementary actions refer here to forms of social interaction wherein individuals adapt their joint actions according to a common aim. Notably, complementary actions are incongruent actions. But being incongruent is not sufficient to be complementary (i.e., to complete the action of another person. Successful complementary interactions are founded on the abilities: (i to simulate another person’s movements, (ii to predict another person’s future action/s, (iii to produce an appropriate incongruent response which differ, while interacting, with observed ones, and (iv to complete the social interaction by integrating the predicted effects of one’s own action with those of another person. This definition clearly alludes to the functional importance of complementary actions in the perception–action cycle and prompts us to scrutinize what is taking place behind the scenes. Preliminary data on this topic have been provided by recent cutting-edge studies utilizing different research methods. This mini-review aims to provide an up-to-date overview of the processes and the specific activations underlying complementary actions.

    Tyrosine kinase inhibition (TKI) such as erlotinib is a well established treatment option in the palliative care of patients with non small cell lung cancer (NSCLC). Histology and sex have been associated with different prognostic outcome measures in patients treated with erlotinib. Furthermore, the degree of rash, developed during treatment might be a relevant marker in respect to tumor response. To dissect these clinical relevant features we analysed a cohort of 275 patients treated with erlotinib in different lines of chemotherapy in our hospital. Nutrition status plays an important role in the prognosis of patients in a palliative chemotherapeutic setting, we therefore included body mass index measurements (BMI) in our analysis. We found that BMI and smoking status influence different survival patterns. Male patients have a poorer survival based on low BMI, rash development and smoking status. We therefore conclude that both nutritional and smoking status should be taken into account in the surveillance of patients with NSCLC in a palliative therapeutic setting under TKI treatment.

    The purpose of this study was to better understand the biological effects of increased prolactin levels induced in mice by dopamine D2 receptor antagonist molindone treatment. Toxicokinetics, prolactin levels, and reproductive tissue histology were evaluated in Tg rasH2 wild-type mice treated orally with molindone at 0, 5, 15, and 50mg/kg/day for 6 months, followed by a 2-month posttreatment recovery period. A greater than dose-proportional increase in molindone exposure ([AUC]0‒24) was observed on Day 180 for both sexes. Statistically significant (Phyperprolactinemia, including corpora lutea enlargement and interstitial cell atrophy in the ovaries, and atrophy of the uterus and vagina were observed on Day 180. These changes were reversed during the recovery period in the 5- and 15-mg/kg/day treatment groups. Mice receiving molindone at 50mg/kg/day also showed signs of reversal on histologic examination.

    Lamotrigine is an antiepileptic drug used for the treatment of epilepsy, bipolar disorder and numerous off-label uses. The development of rash significantly affects its use. The most concerning of these adverse reactions is Stevens-Johnson syndrome/toxic epidermal necrolysis. We performed a systematic review of randomized controlled trials using lamotrigine as a monotherapy to quantify the incidence of cutaneous reactions, particularly Stevens-Johnson syndrome/toxic epidermal necrolysis. Of a total of 4,364 papers regarding lamotrigine, 122 studies met our inclusion and exclusion criteria. In total, 18,698 patients were included with 1,570 (8.3%) of patients experiencing an adverse dermatologic reaction. The incidence of Stevens-Johnson syndrome/toxic epidermal necrolysis was 0.04%.

    2011-11-01

    When other individuals move, we interpret their movements as discrete, hierarchically-organized, goal-directed actions. However, the mechanisms that integrate visible movement features into actions are poorly understood. Here, we consider two sequence learning mechanisms - transitional probability-based (TP) and position-based encoding computations - that have been studied extensively in the domain of language learning, and investigate their potential for integrating movements into actions. If these learning mechanisms integrate movements into actions, then they should create memory units that contain (i) movement information, (ii) information about the order in which movements occurred, and (iii) information allowing actions to be recognized from different viewpoints. We show that both mechanisms retain movement information. However, only the position-based mechanism creates movement representations that are view-invariant and contain order information. The TP-based mechanism creates movement representations that are view-dependent and contain no order information. We therefore suggest that the TP-based mechanism is unlikely to play an important role for integrating movements into actions. In contrast, the position-based mechanism retains some of the types of information needed to represent goal-directed actions, which makes it an attractive target for further research to explore what, if any, role it plays in the perception of goal-directed actions.

  17. THE ACTION RESEARCH METHOD

    Directory of Open Access Journals (Sweden)

    Petre GEORGIEVSKI

    1999-05-01

    Full Text Available The effort in this work to elaborate an action research method as a central research problem considering the recent contemporary sociological and educa­tional literature. The author begins with the statement that the method is a complex notion, composed of three main components: approach to the research problem, data gathering procedures and data analysis procedures. This point of view is further applied and elaborated in the author's text, emphasizing the action research characteristics: interruption with the positive tradition in social research and the divided of the objective and subjective, application of the qualitative data. The sub­stantial difference between the action research in regard with the other kinds of research, is not only in getting to new knowledge's, but also in problem solving or a change in the situation in a concrete social context.

  18. A pruritic linear urticarial rash, fever, and systemic inflammatory disease in five adolescents: adult-onset still disease or systemic juvenile idiopathic arthritis sine arthritis?

    Science.gov (United States)

    Prendiville, Julie S; Tucker, Lori B; Cabral, David A; Crawford, Richard I

    2004-01-01

    The characteristic rash of systemic juvenile idiopathic arthritis is a transient erythematous eruption associated with a quotidian spiking fever. Usually asymptomatic, it can be pruritic, with dermatographism at sites of scratching or pressure. An illness similar to this entity in adults is designated adult-onset Still disease. The relationship between the pediatric and adult disease is uncertain and differences in case definition have evolved. Specifically, a sustained arthritis for at least 6 weeks is required for a diagnosis of systemic juvenile idiopathic arthritis, whereas transient arthritis and arthralgia are accepted criteria in adult-onset Still disease. We describe five patients less than 16 years of age who presented with an acute illness characterized by fever and a distinctive skin eruption. Intense pruritus and linear erythematous lesions flared with a spiking fever, usually in the late afternoon and evening. Periorbital edema/erythema and nonlinear urticarial lesions were also seen. Two children had splinter hemorrhages of the nail beds and one girl developed a fixed, scaling, pigmented, linear eruption. Severe malaise, myalgia, arthralgia, and leukocytosis were present in every patient. Other systemic manifestations included sore throat, transient arthritis, abdominal pain, lymphadenopathy, hepatomegaly, splenomegaly, hyperferritinemia, and hepatic dysfunction. No patient had a sustained arthritis. The course of the disease was variable. One patient, diagnosed with macrophage activation syndrome, recovered on oral naproxen. Two patients responded to systemic corticosteroid therapy. One girl developed status epilepticus and died from aspiration and asphyxia. A boy with severe hepatitis developed renal failure and thrombotic thrombocytopenic purpura and was treated with plasmapheresis, dialysis, and systemic corticosteroids; he had recurrent episodes of rash and fever into adult life. These children did not fulfill the case definition of systemic

  19. What controls nucleosome positions?

    Science.gov (United States)

    Segal, Eran; Widom, Jonathan

    2009-08-01

    The DNA of eukaryotic genomes is wrapped in nucleosomes, which strongly distort and occlude the DNA from access to most DNA-binding proteins. An understanding of the mechanisms that control nucleosome positioning along the DNA is thus essential to understanding the binding and action of proteins that carry out essential genetic functions. New genome-wide data on in vivo and in vitro nucleosome positioning greatly advance our understanding of several factors that can influence nucleosome positioning, including DNA sequence preferences, DNA methylation, histone variants and post-translational modifications, higher order chromatin structure, and the actions of transcription factors, chromatin remodelers and other DNA-binding proteins. We discuss how these factors function and ways in which they might be integrated into a unified framework that accounts for both the preservation of nucleosome positioning and the dynamic nucleosome repositioning that occur across biological conditions, cell types, developmental processes and disease.

    Relative potencies for 30 compounds scheduled for carcinogenic testing in the 2-year rodent bioassays were estimated based on comparisons with a wide variety of bioassay data for benzo[a]pyrene, nicotine, cisplatin, aflatoxin B1, and cyclophosphamide. Potential for oncogenic transformation of each of the compounds was estimated from short-term bioassays. Promoting strength was assigned on the basis of comparisons of the product of relative potency and test dose with the distribution of similar products obtained for 67 common compounds in the data- base of Gold et al. A potency class for promotion was assigned on the basis of whether the potency-adjusted test dosage was > 2{sigma} below the mean, > 1{sigma} below the mean, within {+-}{sigma} of the mean, >{sigma} above the mean, or > 2{sigma} above the mean, as determined from the 67 compounds. The underlying hypothesis is that a weak test dose may have a low probability of revealing a potential carcinogen, whereas a strong dose may have a high probability of producing false-positive results. Predictions are therefore directed at the central 68% of the log-normal frequency distribution according to the assumption that {+-}{sigma} represents the ideal test dose. 22 refs., 7 tabs.

    为了解四川省发热出疹性疾病(RFIs)的血清流行病学特征,以便更好地开展麻疹监测,1997~2000年5月,在该省20个县采集了暴发和散发病例的急性期血清标本,用酶联免疫吸附试验(ELISA)捕捉法检测麻疹和风疹IgM抗体。结果:379例中确诊为麻疹的192例(50.66%),风疹80例(21.11%),其它RFIs 107例(28.23%)。379份血清标本中,麻疹IgM抗体阳性144份,阳性率37.99%;风疹IgM抗体阳性40例(10.55%)。RFIs发病高峰季节为春季,发病以<15岁儿童为主,暴发病例以麻疹为主。血清学诊断是科学鉴别RFIs的重要手段。加强麻疹疫苗的有效接种和强化免疫,是加速控制麻疹的主要策略。%In order to know the sero-epidemiological characteristics of rash and fever illness (RFIs) and carry out measles surveillance well, we collected acute phase serum specimens of epidemic and sporadic RFIs in 20 counties of the province from 1997~May, 2000 and tested for measles IgM and rubella IgM antibody by captured-ELISA. The results showed that of 379 RFIs surveyed, 192 measles cases (50.66%) and 80 rubella cases (21.11%) were diagnosed, the other 107 were RFIs(28.23%). By ELISA test, the serum specimens of measles IgM positive was 144(37.99%), of rubella IgM positive was 40 (10.55%). RFIs occurred highly in spring season, the children<15 years old were chiefly attacked and most of the epidemic RFIs were measles. We hold that sero-diagnosis is the important measure to distinguish RFIs, effective and supplementary measles vaccination is the major strategy to speed up controlling of measles.

    Introduction Diaper dermatitis is referred to the inflammation in outer layers of the skin in the perineal area, lower abdomen, and inner thighs. The lesions are maculopapular and usually itchy, which could cause bacterial or candida infection, and predispose the infants to penis or vaginal and urinary infection and lead to discomfort, irritability, and restlessness. The drugs which have been so far administered for this disease (topical steroids) cause special complications for the sensitive skin in this area. Magnesium (Mg) is known for its anti-inflammatory and wound-healing properties. Aim The aim of the present study was to study the effect of the cream containing Mg 2% on treatment of diaper dermatitis and diaper rash in children. Materials and Methods In this clinical trial study, 64 children aged less than two years old with diaper dermatitis referring Paediatric Ward of Hajar Hospital were randomly assigned to two groups of 32. Group one was treated with the combined cream Mg 2% and Calendula and group two with Calendula cream alone. The duration of recovery was compared between the two groups. Results The duration of recovery was significantly lower in the intervention group than the control group (p-value<0.001), but there was no significant difference in the lesions size and diapers’ number between the two groups. Conclusion Based on the finding of this study, Mg is effective on treatment of diaper dermatitis and could be used for treating diaper dermatitis and other types of dermatitis. PMID:26894161

    Full Text Available Affirmative action was launched by American presidents J.F. Kennedy and L.B. Johnson, yet by ironic historical accident it attained its greatest expansion and most radical form during R. Nixon’s conservative administration. Affirmative action was originally a government programme aimed at improving the social position of Afro-Americans, mostly in the sphere of employment and education, as a kind of compensation for racial discrimination, and also other forms of social injustice suffered by minority and underprivileged groups. Its goal was to increase the proportion of Afro-Americans, and later members of other minorities, as well as women, in higher education institutions and in various types of employment. It was supported by many social researchers and activists. Law courts, namely their verdicts and explanations in the case of precedents, had an especially important role in the debate on affirmative action. Political conservatives attacked various affirmative action programmes (especially preferential enrolment quotas for minority students, basing their criticism on the American constitutional principles on equal rights for every citizen. Market conservatives, furthermore, claimed that the government’s policy of racial preference brought into question the very basis of the capital system (competition and at the same time was not in the interest of the Afro-American working class. Namely, the social strata that profited most was the relatively affluent segment of the Afro-American community, which only increased economic and social differences within the latter. Recently the debate on affirmative action in the US has not been limited only to two opposing sides (liberals and conservatives. More and more scientists and other participants have recognised the negative aspects and also the failures of affirmative action, while at the same time refuting conservative opinions and goals.

    Carlo Fantoni

    2016-02-01

    Full Text Available Fantoni & Gerbino (2014 showed that subtle postural shifts associated with reaching can have a strong hedonic impact and affect how actors experience facial expressions of emotion. Using a novel Motor Action Mood Induction Procedure (MAMIP, they found consistent congruency effects in participants who performed a facial emotion identification task after a sequence of visually-guided reaches: a face perceived as neutral in a baseline condition appeared slightly happy after comfortable actions and slightly angry after uncomfortable actions. However, skeptics about the penetrability of perception (Zeimbekis & Raftopoulos, 2015 would consider such evidence insufficient to demonstrate that observer’s internal states induced by action comfort/discomfort affect perception in a top-down fashion. The action-modulated mood might have produced a back-end memory effect capable of affecting post-perceptual and decision processing, but not front-end perception. Here, we present evidence that performing a facial emotion detection (not identification task after MAMIP exhibits systematic mood-congruent sensitivity changes, rather than response bias changes attributable to cognitive set shifts; i.e., we show that observer’s internal states induced by bodily action can modulate affective perception. The detection threshold for happiness was lower after fifty comfortable than uncomfortable reaches; while the detection threshold for anger was lower after fifty uncomfortable than comfortable reaches. Action valence induced an overall sensitivity improvement in detecting subtle variations of congruent facial expressions (happiness after positive comfortable actions, anger after negative uncomfortable actions, in the absence of significant response bias shifts. Notably, both comfortable and uncomfortable reaches impact sensitivity in an approximately symmetric way relative to a baseline inaction condition. All of these constitute compelling evidence of a genuine top

  17. Substitution of isoleucine for methionine at position 1153 in the beta-subunit of the human insulin receptor. A mutation that impairs receptor tyrosine kinase activity, receptor endocytosis, and insulin action.

    Cama, A; Quon, M J; de la Luz Sierra, M; Taylor, S I

    1992-04-25

    The intracellular domain of the insulin receptor possesses activity as a tyrosine-specific protein kinase. The receptor tyrosine kinase is stimulated by insulin binding to the extracellular domain of the receptor. Previously, we have identified a patient with a genetic form of insulin resistance who is heterozygous for a mutation substituting Ile for Met1153 in the tyrosine kinase domain of the receptor near the cluster of the three major autophosphorylation sites (Tyr1158, Tyr1162, and Tyr1163). In this investigation, the Ile1153 mutant receptor was expressed by transfection of mutant cDNA into NIH-3T3 cells. The mutation impairs receptor tyrosine kinase activity and also inhibits the ability of insulin to stimulate 2-deoxyglucose uptake and thymidine incorporation. These data support the hypothesis that the receptor tyrosine activity plays a necessary role in the ability of the receptor to mediate insulin action in vivo. Furthermore, expression of the Ile1153 mutant receptor exerted a dominant negative effect to inhibit the ability of endogenous murine receptors for insulin and insulin-like growth factor I to mediate their actions upon the cell. This observation is consistent with previous suggestions that mutant receptors dimerize with wild type receptors, thereby creating hybrid molecules which lack biological activity. The dominant negative effect of the mutant receptor may explain the dominant mode of inheritance of insulin resistance caused by the Ile1153 mutation. Finally, the mutation inhibits the ability of insulin to stimulate receptor endocytosis. This may explain the normal number of insulin receptors on the surface of the patient's cells in vivo. Despite the presence of markedly elevated levels of insulin in the patient's plasma, the receptors were resistant to down-regulation.

  19. Positioning Agility

    Science.gov (United States)

    Oza, Nilay; Abrahamsson, Pekka; Conboy, Kieran

    Agile methods are increasingly adopted by European companies. Academics too are conducting numerous studies on different tenets of agile methods. Companies often feel proud in marketing themselves as ‘agile’. However, the true notion of ‘being agile’ seems to have been overlooked due to lack of positioning of oneself for agility. This raises a call for more research and interactions between academia and the industry. The proposed workshop refers to this call. It will be highly relevant to participants, interested in positioning their company’s agility from organizational, group or project perspectives. The positioning of agility will help companies to better align their agile practices with stakeholder values. Results of the workshop will be shared across participants and they will also have opportunity to continue their work on agile positioning in their companies. At broader level, the work done in this workshop will contribute towards developing Agile Positioning System.

  20. Archetypes as action patterns.

    Science.gov (United States)

    Hogenson, George B

    2009-06-01

    The discovery of mirror neurons by researchers at the University of Parma promises to radically alter our understanding of fundamental cognitive and affective states. This paper explores the relationship of mirror neurons to Jung's theory of archetypes and proposes that archetypes may be viewed as elementary action patterns. The paper begins with a review of a proposed interpretation of the fainting spells of S. Freud in his relationship with Jung as an example of an action pattern that also defines an archetypal image. The challenge that mirror neurons present to traditional views in analytical psychology and psychoanalysis, however, is that they operate without recourse to a cognitive processing element. This is a position that is gaining increasing acceptance in other fields as well. The paper therefore reviews the most recent claims made by the Boston Process of Change Study Group as well as conclusions drawn from dynamic systems views of development and theoretical robotics to underline the conclusion that unconscious agency is not a requirement for coherent action. It concludes with the suggestion that this entire body of research may lead to the conclusion that the dynamic unconscious is an unnecessary hypothesis in psychoanalysis and analytical psychology.

  1. Negative and positive urgency may both be risk factors for compulsive buying.

    Descriptions of compulsive buying often emphasize the roles of negative moods and trait impulsivity in the development of problematic buying habits. Trait impulsivity is sometimes treated as a unidimensional trait in compulsive buying research, but recent factor analyses suggest that impulsivity consists of multiple components that are probably best treated as independent predictors of problem behavior. In order to draw greater attention to the role of positive moods in compulsive buying, in this study we tested whether negative urgency (the tendency to act rashly while in negative moods) and positive urgency (the tendency to act rashly while in positive moods) account for similar amounts of variance in compulsive buying. North American adults (N = 514) completed an online survey containing the Richmond Compulsive Buying Scale (Ridgway, Kukar-Kinney & Monroe, 2008), established measures of positive and negative urgency (Cyders et al., 2007), ad hoc measures of buying-specific positive and negative urgency, measures of extraversion and neuroticism obtained from the International Personality Item Pool (http://ipip.ori.org/), and demographic questions. In several multiple regression analyses, when demographic variables, neuroticism, and extraversion were controlled, positive urgency and negative urgency both emerged as significant predictors of compulsive buying. Whether the two urgency variables were domain-general or buying-specific, they accounted for similar amounts of variance in compulsive buying. Preventing and reducing compulsive buying may require attention not only to the purchasing decisions people make while in negative states, but also to the purchasing decisions they make while in positive states.

    An epidemic of rash and fever illnesses suspected of hand,foot and mouth disease (HFMD) occurred in Gansu Province of China in 2008,laboratory tests were performed in order to identify the pathogen that caused this epidemic.Eight clinical specimens collected from the 4 patients (each patient has throat swab and herpes fluid specimens) with rash and febrile illness,were inoculated onto RD and HEp-2 cells for virus isolation,and the viral nucleic acid was then extracted with the positive virus isolates,the dual-channel real-time reverse transcript-polymerase chain reaction (RT-PCR) was performed to detect the nucleic acid of human enterovirus (HEV) in the viral isolates at the same time.For the viral isolates with the negative results of HEV,a sequence independent single primer amplification technique (SISPA) was used for “unknown pathogen“ identification.Totally,6 viral isolates were identified as herpes simplex virus type 1 (HSV-1).Comprehensive analyses results of the clinical manifestations of the patients,epidemiological findings and laboratory test indicated that this epidemic of rash and febrile illness was caused by HSV 1.The differences among the gG region of 6 HSV-1 isolates at nucleotide level and amino acid level were all small,and the identities were up to 98.8% and 97.9%,respectively,showing that this outbreak was caused by only one viral transmission chain of HSV-1.HSV-1 and other viruses that cause rash and febrile illnesses need differential diagnosis with HFMD.The etiology of rash and febrile illness is sometimes difficult to distinguish from the clinical symptoms and epidemiological data,the laboratory diagnosis is therefore critical.%对2008年在甘肃省发生的一起疑似手足口病(HFMD)的发热出疹性疾病的流行进行病原体的实验室检测,明确引起这起传染病流行的病原体.从4名发热出疹患者采集的8份临床标本中(每个患者采集咽拭子和疱疹液标本),首先

    2014-01-01

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

    Experimental relationships have been established between the blackening of emulsions by impinging ions and the following parameters: number, mass and energy of impinging particles. Mean energy ions (about twenty keV) give rise to a latent image probably made of small specks of metallic silver located at the surface or in the bulk of the silver halide grain. A specific developer for ion sensitive emulsion was perfected. Sensitivity and detection threshold are increased by a factor of two or three, compared with values observed using a classical developer. Low energy particles sputtered from superficial layers of the emulsion by the impinging twenty keV ions, produce a latent image close to the surface of the silver halide grain. An oxidizing process bleaches superficial latent image and then reduces background fog. The improved signal over background ratio allows to observe lines undetectable when the plates are developed by usual process.

    Full Text Available In the present action learning implementation, twelve action learning sets were conducted over eight years. The action learning sets consisted of students involved in undergraduate engineering research thesis work. The concurrent study accompanying this initiative, investigated the influence of the action learning environment on student approaches to learning and any accompanying academic, learning and personal benefits realised. The influence of preferred learning styles on set function and student adoption of the action learning process were also examined. The action learning environment implemented had a measurable significant positive effect on student academic performance, their ability to cope with the stresses associated with conducting a research thesis, the depth of learning, the development of autonomous learners and student perception of the research thesis experience. The present study acts as an addendum to a smaller scale implementation of this action learning approach, applied to supervision of third and fourth year research projects and theses, published in 2010.

    Object proposals have contributed significantly to recent advances in object understanding in images. Inspired by the success of this approach, we introduce Deep Action Proposals (DAPs), an effective and efficient algorithm for generating temporal action proposals from long videos. We show how to take advantage of the vast capacity of deep learning models and memory cells to retrieve from untrimmed videos temporal segments, which are likely to contain actions. A comprehensive evaluation indicates that our approach outperforms previous work on a large scale action benchmark, runs at 134 FPS making it practical for large-scale scenarios, and exhibits an appealing ability to generalize, i.e. to retrieve good quality temporal proposals of actions unseen in training.

  4. All in action

    CERN Document Server

    Annila, Arto

    2010-01-01

    The principle of least action provides a holistic worldview in which nature in its entirety and every detail is pictured in terms of actions. Each and every action is ultimately composed of one or multiples of the most elementary action which corresponds to the Planck's constant. Elements of space are closed actions, known as fermions, whereas elements of time are open actions, known as bosons. The actions span energy landscape, the Universe which evolves irreversibly according to the 2nd law of thermodynamics by diminishing density differences in least time. During the step-by-step evolution densely-curled actions unfold by opening up and expelling one or multiple elementary actions to their surrounding sparser space. The manifold's varieties process from one symmetry group to another until the equivalence to their dual, i.e., the surrounding density has been attained. The scale-free physical portrayal of nature does not recognize any fundamental difference between fundamental particles and fundamental force...

    1. The bactericidal action of a number of anionic and cationic synthetic detergents on four Gram-positive and three Gram-negative bacteria has been investigated. 2. Cationic detergents, as a group, were found to exhibit marked bactericidal effects on Gram-positive microorganisms and somewhat less pronounced action on Gram-negative organisms. 3. The anionic detergents were germicidal only against the Gram-positive organisms, and they were considerably less effective than the cationic compounds. Of the anionic detergents, the most active one was an alkyl sulfate derived from a branched-chain, secondary alcohol. 4. Correlations between bactericidal action and inhibition of bacterial metabolism, and also between bactericidal action and chemical structure of the detergents are discussed.

    Full Text Available Parkinson’s disease (PD is a neurodegenerative disorder that markedly affects voluntary action. While regular dopamine treatment can help restore motor function, dopamine also influences cognitive portions of the action system. Previous studies have demonstrated that dopamine medication boosts action-effect associations, which are crucial for the discovery of new voluntary actions. In the present study, we investigated whether neural processes involved in the discovery of new actions are altered in PD participants on regular dopamine treatment, compared to healthy age-match controls. We recorded brain electroencephalography (EEG activity while PD patients and age-matched controls performed action discovery and action control tasks. We found that the novelty P3, a component normally present when there is uncertainty about the occurrence of the sensory effect, was enhanced in PD patients. However, action discovery was maintained in PD patients, and the novelty P3 demonstrated normal learning-related reductions. Crucially, we found that in PD patients the causal association between an action and its resulting sensory outcome did not modulate the amplitude of the feedback correct-related positivity (fCRP, an EEG component sensitive to the association between an action and its resulting effect. Collectively, these preliminary results suggest that the formation of long-term action-outcome representations may be maintained in PD patients on regular dopamine treatment, but the initial experience of action-effect association may be affected.

    Affirmative action is a controversial and often poorly understood policy. It is also a policy that has been widely studied by social scientists. In this review, we outline how affirmative action operates in employment and education settings and consider the major points of controversy. In addition, we detail the contributions of psychologists and other social scientists in helping to demonstrate why affirmative action is needed; how it can have unintended negative consequences; and how affirmative action programs can be most successful. We also review how psychologists have examined variations in people's attitudes toward affirmative action, in part as a means for testing different theories of social behavior.

    We extend a conventional action system with a primitive action consisting of a differential equation and an evolution invariant. The semantics is given by a predicate transformer. The weakest liberal precondition is chosen, because it is not always desirable that steps corresponding to differential...... actions shall terminate. It is shown that the proposed differential action has a semantics which corresponds to a discrete approximation when the discrete step size goes to zero.

    Like any other logical theory, domain descriptions in reasoning about actions may evolve, and thus need revision methods to adequately accommodate new information about the behavior of actions. The present work is about changing action domain descriptions in propositional dynamic logic. Its contribution is threefold: first we revisit the semantics of action theory contraction that has been done in previous work, giving more robust operators that express minimal change based on a notion of distance between Kripke-models. Second we give algorithms for syntactical action theory contraction and establish their correctness w.r.t. our semantics. Finally we state postulates for action theory contraction and assess the behavior of our operators w.r.t. them. Moreover, we also address the revision counterpart of action theory change, showing that it benefits from our semantics for contraction.

    The systematic analysis of acting-out episodes can be used in assessing analytic progress. Variables to be considered are the nature of the wish, the type of defense, and the degree of concreteness (versus symbolization) of the mental processes used in attempting actualization (as distinct from the resort to action). Two acting-out episodes of a borderline patient who acted out as a character trait, both occurring outside the analytic setting, are presented as illustrations. In the first one, occurring relatively early in the analysis, when split-off negative and positive self-images had to be rigidly maintained, ejection of the negative self-image was actualized via the regressive use of a symbolic equation and the mechanism of displacement, obliterating the distinction between an internal feeling and an external thing that here was literally thrown out. The later episode, occurring after the split was healed and within the context of a frustrating heterosexual involvement, contained an acted-out allusion to identification and competition with the mother. As in a dream, via associations, an unconscious wish for oedipal victory was revealed. Whereas in the first episode the goal of ejection was central, with splitting and denial the underlying defenses, it was absent from the second, in which an attempt was made to actualize a repressed infantile wish and made greater use of symbolization. It is concluded that acting-out episodes at different periods of the analysis, when systematically analyzed, can serve in assessing a patient's progress.

    Full Text Available IMGIP and ICEOP are minority graduate fellowship programs sponsored by the State of Illinois in order to increase the number of minority faculty and professional staff at Illinois institutions of higher education through graduate fellowships, networking and mentoring support. Nearly 850 fellowships have been awarded since 1986. A performance audit examined immediate (areas of graduate study, ethnicity of awards, intermediate (graduation areas and rates, and long-range results (academic job placement. The primary source for the audit was the database maintained by the programs' administrative office. These data were compared with data sets maintained by the Illinois Board of Higher Education and with national benchmarks (NSF and Ford Foundation Minority Graduate Fellowships. Findings revealed: (a the IMGIP and ICEOP programs led to major diversification of minority doctoral study in Illinois; (b a high percentage of all fellows graduated, both absolutely and in relation to national benchmarks, and fellows made up a large percentage of doctoral degrees awarded to minorities by Illinois institutions (e.g., 46% of doctorates in the hard sciences awarded to African Americans from 1988-1998; and (c fellows made up an important proportion of all minority faculty in Illinois (9%. Most ICEOP doctoral fellows and many other fellows have taken academic positions. The audit revealed outcomes-based evidence of a successful affirmative action program in higher education—evidence that is not otherwise available.

    Humans are extraordinarily prosocial. What inspires and reinforces a willingness to help others? Here we focus on the role of positive feelings. Drawing on functional accounts of positive emotion, which suggest that positive emotional states serve to alert actors to positive experiences and encourage similar action in the future, we summarize evidence demonstrating that positive feelings promote and reward prosocial behavior throughout development. Specifically, we highlight new and classic evidence from both child and adult research showing first, that various positive states prompt prosocial behavior, and second, prosocial action leads to positive states. We also consider the possibility of a positive feedback loop, wherein the emotional rewards of giving promote future prosociality. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The principle of least action provides a holistic worldview in which Nature in its entirety and every detail is described in terms of actions. Each and every action is ultimately composed of one or multiple of the most elementary actions which relates to Planck’s constant. Elements of space are closed actions, known as fermions, whereas elements of time are open actions, known as bosons. The actions span an energy landscape, the Universe, which evolves irreversibly according to the 2nd law of thermodynamics by diminishing energy density differences in least time. During evolution densely-curled actions unfold step-by-step when opening up and expelling one or multiple elementary actions to their surrounding sparser space. The energy landscape will process from one symmetry group to another until the equivalence to its dual, i.e., the surrounding density has been attained. The scale-free physical portrayal of nature in terms of actions does not recognize any fundamental difference between fundamental particles and fundamental forces. Instead a plethora of particles and a diaspora of forces are perceived merely as diverse manifestations of a natural selection for various mechanisms and ways to decrease free energy in the least time.

    Colloidal oatmeal has a long history of beneficial use in dermatology. It is a natural product that has an excellent safety record and has demonstrated efficacy for the treatment of atopic dermatitis, psoriasis, drug-induced rash and other conditions. In recent years, in vitro and in vivo studies have begun to elucidate the multiple mechanisms of action of naturally derived colloidal oatmeal. Evidence now describes its molecular mechanisms of anti-inflammatory and antihistaminic activity. The avenanthramides, a recently described component of whole oat grain, are responsible for many of these effects. Studies have demonstrated that avenanthramides can inhibit the activity of nuclear factor kappaB and the release of proinflammatory cytokines and histamine, well known key mechanisms in the pathophysiology of inflammatory dermatoses. Topical formulations of natural colloidal oatmeal should be considered an important component of therapy for atopic dermatitis and other conditions and may allow for reduced use of corticosteroids and calcineurin inhibitors.

  4. Antisymmetric string actions

    Aragone, C.

    1986-12-01

    An action is presented for the free bosonic string on external flat space in terms of an antisymmetric second-rank string background tensor which is classically equivalent to the Nambu-Goto action. Both action and field equations are entirely described in terms of 2D world-sheet forms, without any reference to a 2D metric tensor background. The analysis of its canonical formulation shows how the quadratic Virasoro constraints are generated in this case and what their connection with the Bianchi identities are. Since in the orthonormal gauge the reduced action coincides with the standard one, it has the same critical dimension D = 26. The existence of an interaction term of a purely geometric structure stemming in the extrinsic curvature is pointed out. Its action and the new string field equations are then derived. This polynomial antisymmetric string action is uniformly generalized in order to describe d Apartado 80659, Caracas 1080A, Venezuela.

    We have investigated the teaching and learning of the stationary action formulation of classical physics in a first-year university class. Instruction proceeded from the many-paths approach to quantum physics through to ray optics, classical mechanics, and relativity. Student learning and misconceptions were studied with quantitative and qualitative techniques. In particular, an action concept inventory was developed through a process of expert consultation and student feedback. Students reported action physics to be accessible, interesting and valuable.

    Physical theories have their most fundamental expression as action integrals. This suggests that the total action of the universe is the most fundamental physical quantity, and hence finite. In this article it is argued that finite universal action implies that the universe is spatially closed. Further, the possible spatial topologies, the types of matter that can dominate the early universe dynamics, and the form of any quadratic additions to the lagrangian of general relativity are constrained. Initial and final cosmological curvature singularities are required to avoid a universal action singularity.

    Full Text Available Affirmative action embodies a model of compensatory justice which aims al counteracting Discrimination on account of race, colour, sex or creed. This article focuses on race because it has had a devastating effect on blacks in South Africa. The author tries to evaluate the moral merits of affirmative action. An analysis of the ideas of black American conservatives and a South African academic of a perhaps more liberal mind, is used as a means of questioning the widely prevalent liberal legacy. By highlighting its pretensions and inconsistencies a picture of the implications of affirmative action for South Africa emerges that is both a threat and a challenge. Equal opportunities d o not necessarily entail equal results. Other factors such as culture, world view and labour ethos should also be taken into account. The "legacy of dignity" (King is incompatible with the victim-status some blacks exploit. Much was done in South Africa before Julv 1991 that could be labelled affirmative action. The scrapping of the Population Registration A ct as the last pillar of apartheid has tremendous implications for the dignity of blacks. But history promises yet a number of traumatic decades of democratization of the South African community. Positively, affirmative action in South Africa will have tofocus on quality education, bridging courses to enable black students to compete on equal footing for admission, on training employees to qualify for special jobs, community upliftment, housing programmes and the improvement of health services. The most urgent need is the cultivation of a common value system.

    Objectives The anti-HER2 monoclonal antibody trastuzumab and the tyrosine kinase inhibitor lapatinib have complementary mechanisms of action and synergistic antitumour actively in models of HER2-positive breast cancer. However, the efficacy of trastuzumab in combination with lapatinib remains controversial. Therefore, we conducted this meta-analysis to compare combination treatment with lapatinib and trastuzumab to trastuzumab or lapatinib alone in the treatment of HER2-positive breast cancer. Methods Randomised controlled trials (RCTs), published in PubMed, Embase and Web of Science, were systematically reviewed to assess the survival benefits and toxicity profile of HER2-positive patients with breast cancer who were treated with lapatinib and trastuzumab. Outcomes included pathological complete response (pCR), event-free survival (EFS), overall survival (OS) and toxicities. Results were expressed as the risk ratio (RR) or HR with 95% CIs. Pooled estimates were calculated by using a fixed-effects model or a randomised-effects model. Results A total of 7 RCTs involving 2084 patients met the inclusion criteria and were included in this meta-analysis. The combination of lapatinib and trastuzumab significantly improved pCR (RR=1.43, 95% CI 1.23 to 1.67; p<0.001), EFS (HR=0.75, 95% CI 0.60 to 0.93; p=0.009) and OS (HR=0.72, 95% CI 0.56 to 0.93; p=0.011) in the treatment of HER2-positive breast cancer compared with trastuzumab or lapatinib alone. The combination treatment also increased the pCR irrespective of hormone receptor status and tumour size. More frequent grade 3 or 4 adverse events, including diarrhoea, rash or erythema, neutropenia and hepatic adverse events, were found in the combination group than in the trastuzumab or lapatinib group. Conclusions On the basis of the current evidence, our results reveal that the addition of lapatinib to trastuzumab can significantly improve pCR, EFS and OS with a tolerated toxicity in patients with HER2-positive breast

    Full Text Available Positive objects or actions are associated with physical highness, whereas negative objects or actions are related to physical lowness. Previous research suggests that metaphorical connection (good is up or bad is down between spatial experience and evaluation of objects is grounded in actual experience with the body. Prior studies investigated effects of spatial metaphors with respect to verticality of either static objects or self-performed actions. By presenting videos of object placements, the current three experiments combined vertically-located stimuli with observation of vertically-directed actions. As expected, participants’ ratings of emotionally-neutral objects were systematically influenced by the observed vertical positioning, that is, ratings were more positive for objects that were observed being placed up as compared to down. Moreover, effects were slightly more pronounced for bad is down, because only the observed downward, but not the upward, action led to different ratings as compared to a medium-positioned action. Last, some ratings were even affected by observing only the upward/downward action, without seeing the final vertical placement of the object. Thus, both, a combination of observing a vertically-directed action and seeing a vertically-located object, and observing a vertically-directed action alone, affected participants’ evaluation of emotional valence of the involved object. The present findings expand the relevance of spatial metaphors to action observation, thereby giving new impetus to embodied-cognition research.

  6. Action spectra again?

    Science.gov (United States)

    Coohill, T P

    1991-11-01

    Action spectroscopy has a long history and is of central importance to photobiological studies. Action spectra were among the first assays to point to chlorophyll as the molecule most responsible for plant growth and to DNA as the genetic material. It is useful to construct action spectra early in the investigation of new areas of photobiological research in an attempt to determine the wavelength limits of the radiation region causing the studied response. But due to the severe absorption of ultraviolet (UV) radiation by biological samples, UV action spectra were first limited to small cells (bacteria and fungi). Advances in techniques (e.g. single cell culture) and analysis allowed accurate action spectra to be reported even for mammalian cells. But precise analytical action spectra are often difficult to obtain when large, pigmented, or groups of cells are investigated. Here some action spectra are limited in interpretation and merely supply a wavelength vs effect curve. When polychromatic sources are employed, the interpretation of action spectra is even more complex and formidable. But such polychromatic action spectra can be more directly related to ambient responses. Since precise action spectra usually require the completion of a relatively large number of careful experiments using somewhat sophisticated equipment over a range of at least six wavelengths, they are often not pursued. But they remain central to the elucidation of the effect being studied. The worldwide community has agreed that stratospheric ozone is depleting, with the possibility of a consequent rise in the amount of UV-B (290-320 nm) reaching the earth's surface. It is therefore essential that new action spectra be completed for UV-B effects on a large variety of responses of human, animal, and aquatic plant systems. Combining these action spectra with the known amounts of UV-B reaching the biosphere can give rise to solar UV effectiveness spectra that, in turn, can give rise to estimates

  8. Path integrals for awkward actions

    CERN Document Server

    Amdahl, David

    2016-01-01

    Time derivatives of scalar fields occur quadratically in textbook actions. A simple Legendre transformation turns the lagrangian into a hamiltonian that is quadratic in the momenta. The path integral over the momenta is gaussian. Mean values of operators are euclidian path integrals of their classical counterparts with positive weight functions. Monte Carlo simulations can estimate such mean values. This familiar framework falls apart when the time derivatives do not occur quadratically. The Legendre transformation becomes difficult or so intractable that one can't find the hamiltonian. Even if one finds the hamiltonian, it usually is so complicated that one can't path-integrate over the momenta and get a euclidian path integral with a positive weight function. Monte Carlo simulations don't work when the weight function assumes negative or complex values. This paper solves both problems. It shows how to make path integrals without knowing the hamiltonian. It also shows how to estimate complex path integrals b...

    The Food and Drug Administration's Mini-Sentinel pilot program aims to conduct active surveillance to refine safety signals that emerge for marketed medical products. A key facet of this surveillance is to develop and understand the validity of algorithms for identifying health outcomes of interest from administrative and claims data. This article summarizes the process and findings of the algorithm review of hypersensitivity reactions. PubMed and Iowa Drug Information Service searches were conducted to identify citations applicable to the hypersensitivity reactions of health outcomes of interest. Level 1 abstract reviews and Level 2 full-text reviews were conducted to find articles using administrative and claims data to identify hypersensitivity reactions and including validation estimates of the coding algorithms. We identified five studies that provided validated hypersensitivity-reaction algorithms. Algorithm positive predictive values (PPVs) for various definitions of hypersensitivity reactions ranged from 3% to 95%. PPVs were high (i.e. 90%-95%) when both exposures and diagnoses were very specific. PPV generally decreased when the definition of hypersensitivity was expanded, except in one study that used data mining methodology for algorithm development. The ability of coding algorithms to identify hypersensitivity reactions varied, with decreasing performance occurring with expanded outcome definitions. This examination of hypersensitivity-reaction coding algorithms provides an example of surveillance bias resulting from outcome definitions that include mild cases. Data mining may provide tools for algorithm development for hypersensitivity and other health outcomes. Research needs to be conducted on designing validation studies to test hypersensitivity-reaction algorithms and estimating their predictive power, sensitivity, and specificity.

Acknowledging that talk gives rise to different expectations over time, we put forward ideal types of organizational strategies for possible talk-action relationships....... While we illustrate our theoretical points with examples from both corporate and political contexts, we draw especially on the field of corporate social responsibility (as an extreme case) where expectations of consistency between talk and actions are most explicitly pronounced....

  12. Actions for Curved Branes

    CERN Document Server

    Abou-Zeid, M

    2000-01-01

    The nondeterminantal forms of the Born-Infeld and related brane actions in which the gauge fields couple to both an induced metric and an intrinsic metric are generalised by letting either or both metrics be dynamical. The resulting actions describe ` brane world' and cosmological scenarios in which the gauge fields are confined to the brane, while gravity propagates in both the world-volume and the bulk. In particular, for actions involving a nonsymmetric ` metric', nonsymmetric gravity propagates on the worldvolume. For 3-branes with a symmetric metric, conformal (Weyl) gravity propagates on the worldvolume and has conformally invariant couplings to the gauge fields.

  13. Violence as Situational Action

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available Violence comes in many forms and occurs in many different circumstances for many different reasons. Is it really possible to develop a single theory that can explain all these disparate acts? In this paper, we argue it is. We make the case that acts of violence are essentially moral actions and therefore can, and should, be analysed and explained as such. We maintain that all acts of violence can be explained within the general framework of a theory of moral action. We present just such a theory – Situational Action Theory – and demonstrate how it can be applied to the explanation and study of violence.

  14. Reasoning about Unreliable Actions

    CERN Document Server

    White, Graham

    2012-01-01

    We analyse the philosopher Davidson's semantics of actions, using a strongly typed logic with contexts given by sets of partial equations between the outcomes of actions. This provides a perspicuous and elegant treatment of reasoning about action, analogous to Reiter's work on artificial intelligence. We define a sequent calculus for this logic, prove cut elimination, and give a semantics based on fibrations over partial cartesian categories: we give a structure theory for such fibrations. The existence of lax comma objects is necessary for the proof of cut elimination, and we give conditions on the domain fibration of a partial cartesian category for such comma objects to exist.

    We introduce the formalism of action investment energy games where we study the trade-off between investments limited by given budgets and resource constrained (energy) behavior of the underlying system. More specifically, we consider energy games extended with costs of enabling actions and fixed...... budgets for each player. We ask the question whether for any Player 2 investment there exists a Player 1 investment such that Player 1 wins the resulting energy game. We study the action investment energy game for energy intervals with both upper and lower bounds, and with a lower bound only, and give...... a complexity results overview for the problem of deciding the winner in the game....

  16. Spacelike brane actions.

    Hashimoto, Koji; Ho, Pei-Ming; Wang, John E

    2003-04-11

    We derive effective actions for "spacelike branes" (S-branes) and find a solution describing the formation of fundamental strings in the rolling tachyon background. The S-brane action is a Dirac-Born-Infeld action for Euclidean world volumes defined in the context of time-dependent tachyon condensation of non-BPS (Bogomol'nyi-Prasad-Sommerfield) branes. It includes gauge fields and, in particular, a scalar field associated with translation along the time direction. We show that the BIon spike solutions constructed in this system correspond to the production of a confined electric flux tube (a fundamental string) at late time of the rolling tachyon.

  17. Knowledge in action in weaving

    2014-04-01

    Full Text Available The project “Design, craft and culture” had the purpose of co-production of knowledge between the University of Borås and the small-scale enterprise Vävkompaniet (The weaving company. The practitioners’ wanted to get insights into competences previously “hidden” in their knowledge in action; competences that could be the base for development of products and ways to reach customers. From academic point of view the main goal was to produce films aimed shedding light on knowledge in action. The result is four educational films aimed at students.This article is based on interpretations of films and interviews from places where the handweavers produce their products. A researcher and a weaving teacher studied their work, while the photographer filmed the artisans’ body movements. Questions and words, in a language which fits the events of the practice, can make practitioners sharpen their attention and direct it at critical points in the practice that they accomplish. By interviews done in a conversation-like way during observations, a space for such reflections was created. The weavers shared meanings on their position in the field of craft and detailed descriptions of crafting practices with the research team. Regarding the design process, because of their material rather than conceptual approach to craftwork, the weavers brought up the importance of sample weaving. While work with dressing the looms and weaving then continued many empirical examples of aspects of knowledge in action could be observed. The importance of routine, rhythm, bodily skills, senses, judgement and experience are brought up in the text.Key words: textile craft, weaving, tacit knowledge, knowledge in action, senses, visual ethnography

  18. Action research: genesis, evolution and orientations

    Directory of Open Access Journals (Sweden)

    Angie Titchen

    2015-05-01

    Full Text Available Background: Action research is used to bring about systematic change at the same time as developing fresh understanding about the change strategy and its impact. It has been around since the 1940s in a variety of forms and for different purposes. It is increasingly used as a practice development research strategy in healthcare professions. Aim and objectives: The aim is to provide an overview of action research to enable understanding of the flow and the cumulative, interactive nature of action research and its evolution. The objectives of the paper are practical, historical and paradigmatic in nature. Methods: Drawing on personal and others’ development and on experience of action research, the paper is a blend of scholarly writing, practical examples and the metaphor of a tidal river estuary. The metaphor uses continuous reshaping of sandbanks to symbolise the coming together and moving apart of different streams of action research. Exposition: The origins and evolution of action research, with its different purposes, orientations and emphases, are shown through an analysis and critique of different definitions of action research over time. With differences identified, common characteristics of action research and the creation of action hypotheses are set out, followed by the history and evolution of action research, separated into four major modes. Paradigmatic origins and assumptions of these modes are critiqued. Conclusion and implications for practice development research: In common with all researchers, practice development researchers need to consider carefully which paradigmatic assumptions are most relevant to their questions and purposes because those assumptions will help them to locate their work in an appropriate specific or blended research paradigm. The choice of paradigm will affect everything they do and are, so the choice needs to be made from an informed and embodied position.

    We link the study of positive quantum maps, block positive operators, and entanglement witnesses with problems related to multivariate polynomials. For instance, we show how indecomposable block positive operators relate to biquadratic forms that are not sums of squares. Although the general problem of describing the set of positive maps remains open, in some particular cases we solve the corresponding polynomial inequalities and obtain explicit conditions for positivity.

  11. [Addictions and action systems].

    Science.gov (United States)

    Loonis, E; Apter, M J

    2000-01-01

    Generalizing from some previous analyses of addiction, and introducing the concept of an action system which governs all actions which are focussed on what Brown (1988) calls "hedonic management", we argue that addictions of every kind involve an action system that displays high salience, low variety and low vicariance. Addictions also involve what Apter (1982) calls the "paratelic state". A study was carried out comparing 31 drug addicts with 29 control subjects in terms of action system variables. To measure these variables, we constructed a new instrument, the Activity-System Drawing Test, and also used the Telic Dominance Scale to measure frequency of paratelic states. Dysphoria was measured by means of the BATE (anxiety), IDA-13 (depression), SEI (self-esteem), and TAS-20 (alexithymia) instruments. Strongly significant differences were found between groups for both action system variables and dysphoria, and there were also strong correlations between both groups of variables. This supports the idea that addictions emerge from systemic properties of the action system.

  12. Topological Lattice Actions

    CERN Document Server

    Bietenholz, W; Pepe, M; Wiese, U -J

    2010-01-01

    We consider lattice field theories with topological actions, which are invariant against small deformations of the fields. Some of these actions have infinite barriers separating different topological sectors. Topological actions do not have the correct classical continuum limit and they cannot be treated using perturbation theory, but they still yield the correct quantum continuum limit. To show this, we present analytic studies of the 1-d O(2) and O(3) model, as well as Monte Carlo simulations of the 2-d O(3) model using topological lattice actions. Some topological actions obey and others violate a lattice Schwarz inequality between the action and the topological charge $Q$. Irrespective of this, in the 2-d O(3) model the topological susceptibility $\\chi_t = \\l/V$ is logarithmically divergent in the continuum limit. Still, at non-zero distance the correlator of the topological charge density has a finite continuum limit which is consistent with analytic predictions. Our study shows explicitly that some cla...

  15. Negative emotional outcomes attenuate sense of agency over voluntary actions.

    Science.gov (United States)

    Yoshie, Michiko; Haggard, Patrick

    2013-10-21

    Sense of agency (SoA) refers to the feeling that one's voluntary actions produce external sensory events [1, 2]. Several psychological theories hypothesized links between SoA and affective evaluation [3-6]. For example, people tend to attribute positive outcomes to their own actions, perhaps reflecting high-level narrative processes that enhance self-esteem [3]. Here we provide the first evidence that such emotional modulations also involve changes in the low-level sensorimotor basis of agency. The intentional binding paradigm [1] was used to quantify the subjective temporal compression between a voluntary action and its sensory consequences, providing an implicit measure of SoA. Emotional valence of action outcomes was manipulated by following participants' key-press actions with negative or positive emotional vocalizations [7], or neutral sounds. We found that intentional binding was reduced for negative compared to positive or neutral outcomes. Discriminant analyses identified a change in time perception of both actions and their negative outcomes, demonstrating that the experience of action itself is subject to affective modulation. A small binding benefit was also found for positive action outcomes. Emotional modulation of SoA may contribute to regulating social behavior. Correctly tracking the valenced effects of one's voluntary actions on other people could underlie successful social interactions.

  17. Alectinib for choroidal metastasis in a patient with crizotinib-resistant ALK rearranged positive non-small cell lung cancer.

    2015-01-01

    Choroidal metastasis is rare in cancer patients. Small molecules of molecular targeted agents for lung cancer with actionable mutations were reported to be palliated for symptoms caused by choroidal metastasis. Visual disturbance by choroidal metastasis significantly decreases quality of life during the patient's remaining lifespan; therefore, radiotherapy or laser photocoagulation is proposed with consensus. However, improvement in survival with matched molecular targeted agents for oncogenic driver mutations reminds us to also be concerned with late treatment toxicities. A 30-year-old female patient previously treated with crizotinib harboring ALK rearranged non-small cell lung cancer complained of visual disturbance, fever, and bone pains undergoing anti-PD-1 antibody treatment. A decreased proportion of ALK fusion was demonstrated by fluorescence in situ hybridization in liver metastasis compared to the primary site in a chemo-naïve state. She was diagnosed with low vision, choroidal metastasis and retinal detachment. Therefore, she started alectinib treatment and both her ocular and systemic symptoms were palliated in a week. Later, she temporarily discontinued alectinib because of skin rash although the choroidal metastasis and retinal detachment resolved and she regained low vision completely at 2 weeks. She obtained partial response with alectinib for more than 5 months after recovering from skin rash.

  19. Hedonic value of intentional action provides reinforcement for voluntary generation but not voluntary inhibition of action.

    Science.gov (United States)

    Parkinson, Jim; Haggard, Patrick

    2013-12-01

    Intentional inhibition refers to stopping oneself from performing an action at the last moment, a vital component of self-control. It has been suggested that intentional inhibition is associated with negative hedonic value, perhaps due to the frustration of cancelling an intended action. Here we investigate hedonic implications of the free choice to act or inhibit. Participants gave aesthetic ratings of arbitrary visual stimuli that immediately followed voluntary decisions to act or to inhibit action. We found that participants for whom decisions to act produced a strong positive hedonic value for the immediately following visual stimulus made more choices to act than those with weaker hedonic value for action. This finding is consistent with reinforcement learning of action decisions. However, participants who experienced inhibition as generating more positive hedonic value did not choose to inhibit more than other participants. Thus, voluntary inhibition of action did not act as reinforcement for future inhibitory behaviour. Our finding that inhibition of action lacks motivational capacity may explain why self-control is both difficult and limited.

  1. Classifying Facial Actions

    Donato, Gianluca; Bartlett, Marian Stewart; Hager, Joseph C.; Ekman, Paul; Sejnowski, Terrence J.

    2010-01-01

    The Facial Action Coding System (FACS) [23] is an objective method for quantifying facial movement in terms of component actions. This system is widely used in behavioral investigations of emotion, cognitive processes, and social interaction. The coding is presently performed by highly trained human experts. This paper explores and compares techniques for automatically recognizing facial actions in sequences of images. These techniques include analysis of facial motion through estimation of optical flow; holistic spatial analysis, such as principal component analysis, independent component analysis, local feature analysis, and linear discriminant analysis; and methods based on the outputs of local filters, such as Gabor wavelet representations and local principal components. Performance of these systems is compared to naive and expert human subjects. Best performances were obtained using the Gabor wavelet representation and the independent component representation, both of which achieved 96 percent accuracy for classifying 12 facial actions of the upper and lower face. The results provide converging evidence for the importance of using local filters, high spatial frequencies, and statistical independence for classifying facial actions. PMID:21188284

  2. Rethinking therapeutic action.

    Science.gov (United States)

    Gabbard, Glen O; Westen, Drew

    2003-08-01

    Like other core psychoanalytic constructs, the theory of therapeutic action is currently in flux, as theorists of differing persuasions propose different mechanisms. In this article, the authors attempt to integrate developments within and without psychoanalysis to provide a working model of the multifaceted processes involved in producing change in psychoanalysis and psychoanalytic psychotherapy. A theory of therapeutic action must describe both what changes (the aims of treatment) and what strategies are likely to be useful in facilitating those changes (technique). The authors believe that single-mechanism theories of therapeutic action, no matter how complex, are unlikely to prove useful at this point because of the variety of targets of change and the variety of methods useful in effecting change in those targets (such as techniques aimed at altering different kinds of conscious and unconscious processes). Interventions that facilitate change may be classified into one of three categories: those that foster insight, those that make use of various mutative aspects of the treatment relationship and a variety of secondary strategies that can be of tremendous importance. They propose that, in all forms of psychoanalytic treatment, we would be more accurate to speak of the therapeutic actions, rather than action.

  4. Post-Colonial Theory and Action Research

    Directory of Open Access Journals (Sweden)

    Jim B. Parsons

    2011-04-01

    Full Text Available This essay explores connections between post-colonial theory and action research. Post-colonial theory is committed to addressing the plague of colonialism. Action research, at its core, promises to problematize uncontested ‘colonial’ hegemonies of any form. Both post-colonial theory and action research engage dialogic, critically reflective and collaborative values to offer a fuller range of human wisdom. The authors contend that post-colonialism theory calls for justice and seeks to speak to social and psychological suffering, exploitation, violence and enslavement done to the powerless victims of colonization around the world by challenging the superiority of dominant perspectives and seeking to re-position and empower the marginalized and subordinated. In similar ways, action research works to eradicate oppression, powerlessness and worthlessness by affirming solidarity with the oppressed, helping humans move from passive to active and by fundamentally reshaping power. Because both post-colonial theory and action research position the insider or oppressed in an ethic of efficacy, it values community, relationships, communication and equality, and is committed to reciprocity, reflexivity and reflection. Thus, both hold the potential to help reconstruct conditions for a more democratic and just society.

    2004-03-01

    Three kinds of proper actions of increasing strength are defined. We prove that the three definitions specialize to the definitions by Bourbaki, by Palais and by Baum, Connes and Higson in their respective settings. The third of these, which thus turns out to be the strongest, originally only concerns actions of second countable locally compact groups on metrizable spaces. In this situation, it is shown to coincide with the other two definitions if the total space locally has the Lindelöf property and the orbit space is regular.

  2. Interweaving reason, action, and perception

    Science.gov (United States)

    Fennema, Claude L., Jr.

    1992-11-01

    In an attempt to understand and emulate intelligent behavior Artificial Intelligence researchers have, for the most part, taken a reductionist approach and divided their investigation into separate studies of reason, perception, and action. As a consequence, intelligent robots have been constructed using a coarse grained architecture; reasoning, perception, and action have been implemented as separate modules that interact infrequently. This paper describes an investigation into the effect of reducing this architecture granularity on the computational efficiency of the overall system. It demonstrates that introducing a fine grained integration or `interweaving' of these functions can result in significant complexity reduction. This paper introduces the `reason a little, move a little, look a little,' or RML paradigm, describes an RML navigation system, and discusses analytical and experimental results that quantify complexity reduction for planning and vision. The system details illustrate novel approaches to representation, planning, and vision. The environment is represented as a network that provides mechanisms for coping with positional uncertainty and focusing reasoning activities. Plans are constructed in three dimensions using a geometry-induced hierarchical decomposition. The approach to vision takes its lead from the way a blind man uses his cane: to verity that reason is consistent with reality.

  8. Duality symmetric actions

    CERN Document Server

    Schwarz, J H; Schwarz, John H.; Sen, Ashoke

    1994-01-01

    It is frequently useful to construct dual descriptions of theories containing antisymmetric tensor fields by introducing a new potential whose curl gives the dual field strength, thereby interchanging field equations with Bianchi identities. We describe a general procedure for constructing actions containing both potentials at the same time, such that the dual relationship of the field strengths arises as an equation of motion. The price for doing this is the sacrifice of manifest Lorentz invariance or general coordinate invariance, though both symmetries can be realized nonetheless. There are various examples of global symmetries that have been realized as symmetries of field equations but not actions. These can be elevated to symmetries of the action by our method. The main example that we focus on is the low-energy effective action description of the heterotic string theory compactified on a six-torus to four dimensions. We show that the SL(2,R) symmetry, whose SL(2,Z) subgroup has been conjectured to be a...

  14. Cognitive framing in action.

    Huhn, John M; Potts, Cory Adam; Rosenbaum, David A

    2016-06-01

    Cognitive framing effects have been widely reported in higher-level decision-making and have been ascribed to rules of thumb for quick thinking. No such demonstrations have been reported for physical action, as far as we know, but they would be expected if cognition for physical action is fundamentally similar to cognition for higher-level decision-making. To test for such effects, we asked participants to reach for a horizontally-oriented pipe to move it from one height to another while turning the pipe 180° to bring one end (the "business end") to a target on the left or right. From a physical perspective, participants could have always rotated the pipe in the same angular direction no matter which end was the business end; a given participant could have always turned the pipe clockwise or counter-clockwise. Instead, our participants turned the business end counter-clockwise for left targets and clockwise for right targets. Thus, the way the identical physical task was framed altered the way it was performed. This finding is consistent with the hypothesis that cognition for physical action is fundamentally similar to cognition for higher-level decision-making. A tantalizing possibility is that higher-level decision heuristics have roots in the control of physical action, a hypothesis that accords with embodied views of cognition.

    2013-08-01

    Disorders of the brain and its sensory organs have traditionally been associated with deficits in movement, perception, cognition, emotion, and behavior. It is increasingly evident, however, that positive phenomena may also occur in such conditions, with implications for the individual, science, medicine, and for society. This article provides a selective review of such positive phenomena--enhanced function after brain lesions, better-than-normal performance in people with sensory loss, creativity associated with neurological disease, and enhanced performance associated with aging. We propose that, akin to the well-established field of positive psychology and the emerging field of positive clinical psychology, the nascent fields of positive neurology and positive neuropsychology offer new avenues to understand brain-behavior relationships, with both theoretical and therapeutic implications.

The results are in agreement with earlier calculations of N^* resonances using improved actions and exhibit a clear mass splitting between the nucleon and its chiral partner, even for the Wilson fermion action. The results also indicate a splitting between the lowest J^P = 1/2^- states for the two standard nucleon interpolating fields.

    2015-06-01

    A statistical generalization of microeconomics has been made in Baaquie (2013), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is modeled by an action functional-and the focus of this paper is to empirically determine the action functionals for different commodities. The correlation functions of the model are defined using a Feynman path integral. The model is calibrated using the unequal time correlation of the market commodity prices as well as their cubic and quartic moments using a perturbation expansion. The consistency of the perturbation expansion is verified by a numerical evaluation of the path integral. Nine commodities drawn from the energy, metal and grain sectors are studied and their market behavior is described by the model to an accuracy of over 90% using only six parameters. The paper empirically establishes the existence of the action functional for commodity prices that was postulated to exist in Baaquie (2013).

  5. Finding minimal action sequences with a simple evaluation of actions

    2014-11-01

    Full Text Available Animals are able to discover the minimal number of actions that achieves an outcome (the minimal action sequence. In most accounts of this, actions are associated with a measure of behavior that is higher for actions that lead to the outcome with a shorter action sequence, and learning mechanisms find the actions associated with the highest measure. In this sense, previous accounts focus on more than the simple binary signal of ``was the outcome achieved?''; they focus on ``how well was the outcome achieved?'' However, such mechanisms may not govern all types of behavioral development. In particular, in the process of action discovery (Redgrave and Gurney, 2006, actions are reinforced if they simply lead to a salient outcome because biological reinforcement signals occur too quickly to evaluate the consequences of an action beyond an indication of the outcome's occurrence. Thus, action discovery mechanisms focus on the simple evaluation of ``was the outcome achieved?'' and not ``how well was the outcome achieved?'' Notwithstanding this impoverishment of information, can the process of action discovery find the minimal action sequence? We address this question by implementing computational mechanisms, referred to in this paper as no-cost learning rules, in which each action that leads to the outcome is associated with the same measure of behavior. No-cost rules focus on ``was the outcome achieved?'' and are consistent with action discovery. No-cost rules discover the minimal action sequence in simulated tasks and execute it for a substantial amount of time. Extensive training, however, results in extraneous actions, suggesting that a separate process (which has been proposed in action discovery must attenuate learning if no-cost rules participate in behavioral development. We describe how no-cost rules develop behavior, what happens when attenuation is disrupted, and relate the new mechanisms to wider computational and biological context.

We introduce several different learning......In dynamic epistemic logic, actions are described using action models. In this paper we introduce a framework for studying learnability of action models from observations. We present first results concerning propositional action models. First we check two basic learnability criteria: finite...... identifiability (conclusively inferring the appropriate action model in finite time) and identifiability in the limit (inconclusive convergence to the right action model). We show that deterministic actions are finitely identifiable, while non-deterministic actions require more learning power...

The sample consisted of 14 HIV-infected, asymptomatic pregnant women, in their third month, who were aware of their condition before getting pregnant. An interview was carried out from 2001 to 2002 in order to collect data. The Collective Subject Discourse Method was adopted for data analysis. It was observed that the pregnant women had similar expectations concerning motherhood. They got used to pregnancy and believed their baby would be HIV negative and that treatment would be effective. There is a need to implement counseling about women's health with a focus on perinatal HIV/aids transmission.

  11. Rethinking actions: implementation and association.

    Quandt, Lorna C; Chatterjee, Anjan

    2015-01-01

    Action processing allows us to move through and interact with the world, as well as understand the movements performed by other people. In recent years, there has been increasing interest in the semantics of actions as differentiated from the semantics of objects. However, as the understanding of action semantics has evolved, it is evident that the existing literature conflates two senses of the word 'action'-one that stems from studies of tool use and the other from event representation. In this paper, we suggest that this issue can be clarified by closely examining differences in how the human parietal and temporal cortices of the brain process action-related stimuli. By contrasting the posterior parietal cortex to the posterolateral temporal cortex, we characterize two complementary action systems in the human brain, each with its own specialization of function. We suggest that these two systems be referred to as the parietal Action Implementation System, and the posterolateral temporal Action Association System. While the frontoparietal system is concerned primarily with how we perform actions, and simulate others' actions, the temporal action system is more involved with processing actions from a third-person, conceptual standpoint. Recent work in cognitive neuroscience of perception and language, as well as the neuroanatomical organization of these brain regions support this distinction. We will discuss the implications of this work for cognition-, language-, and neuroscience-based action research. © 2015 Wiley Periodicals, Inc.

    We conjecture that the quantum complexity of a holographic state is dual to the action of a certain spacetime region that we call a Wheeler-DeWitt patch. We illustrate and test the conjecture in the context of neutral, charged, and rotating black holes in AdS, as well as black holes perturbed with static shells and with shock waves. This conjecture evolved from a previous conjecture that complexity is dual to spatial volume, but appears to be a major improvement over the original. In light of our results, we discuss the hypothesis that black holes are the fastest computers in nature.

    We present a computational approach to radical rhetoric that leverages the co-expression of rhetoric and action features in discourse to identify violent intent. The approach combines text mining and machine learning techniques with insights from Frame Analysis and theories that explain the emergence of violence in terms of moral disengagement, the violation of sacred values and social isolation in order to build computational models that identify messages from terrorist sources and estimate their proximity to an attack. We discuss a specific application of this approach to a body of documents from and about radical and terrorist groups in the Middle East and present the results achieved.

    Tausch, Nicole; Becker, Julia C; Spears, Russell; Christ, Oliver; Saab, Rim; Singh, Purnima; Siddiqui, Roomana N

    2011-07-01

    A recent model of collective action distinguishes 2 distinct pathways: an emotional pathway whereby anger in response to injustice motivates action and an efficacy pathway where the belief that issues can be solved collectively increases the likelihood that group members take action (van Zomeren, Spears, Fischer, & Leach, 2004). Research supporting this model has, however, focused entirely on relatively normative actions such as participating in demonstrations. We argue that the relations between emotions, efficacy, and action differ for more extreme, nonnormative actions and propose (a) that nonnormative actions are often driven by a sense of low efficacy and (b) that contempt, which, unlike anger, entails psychological distancing and a lack of reconciliatory intentions, predicts nonnormative action. These ideas were tested in 3 survey studies examining student protests against tuition fees in Germany (N = 332), Indian Muslims' action support in relation to ingroup disadvantage (N = 156), and British Muslims' responses to British foreign policy (N = 466). Results were generally supportive of predictions and indicated that (a) anger was strongly related to normative action but overall unrelated or less strongly related to nonnormative action, (b) contempt was either unrelated or negatively related to normative action but significantly positively predicted nonnormative action, and (c) efficacy was positively related to normative action and negatively related to nonnormative action. The implications of these findings for understanding and dealing with extreme intergroup phenomena such as terrorism are discussed.

    2015-06-01

    Although individuals scoring high on Neuroticism tend to avoid taking action when faced with challenges, Neuroticism is also characterized by impulsivity. To explore cognitive biases related to this costly behavior pattern, we tested whether individuals who rated themselves as higher in Neuroticism would evaluate the general concepts of action and inaction as, respectively, more negative and positive. We further investigated whether anxiety and depression would mediate and individualism-collectivism would moderate these relations in a large international sample. Participants (N = 3,827 college students; 69% female) from 19 countries completed surveys measuring Neuroticism, attitudes toward action and inaction, depression, anxiety, and individualism-collectivism. Hierarchical linear models tested the above predictions. Neuroticism negatively correlated with attitudes toward action and positively correlated with attitudes toward inaction. Furthermore, anxiety was primarily responsible for emotionally unstable individuals' less positive attitudes toward action, and individuals who endorsed more collectivistic than individualistic beliefs showed a stronger negative association between Neuroticism and attitudes toward action. Researchers and practitioners interested in understanding and remediating the negative consequences of Neuroticism should pay greater attention to attitudes toward action and inaction, particularly focusing on their links with anxiety and individualism-collectivism.

    When a reinforcement learning agent executes actions that can cause frequent damage to itself, it can learn, by using Q-learning, that these actions must not be executed again. However, there are other actions that do not cause damage frequently but only once in a while, for example, risky actions such as parachuting. These actions may imply punishment to the agent and, depending on its personality, it would be better to avoid them. Nevertheless, using the standard Q-learning algorithm, the a...

    Pastra, Katerina; Aloimonos, Yiannis

    2012-01-12

    Language and action have been found to share a common neural basis and in particular a common 'syntax', an analogous hierarchical and compositional organization. While language structure analysis has led to the formulation of different grammatical formalisms and associated discriminative or generative computational models, the structure of action is still elusive and so are the related computational models. However, structuring action has important implications on action learning and generalization, in both human cognition research and computation. In this study, we present a biologically inspired generative grammar of action, which employs the structure-building operations and principles of Chomsky's Minimalist Programme as a reference model. In this grammar, action terminals combine hierarchically into temporal sequences of actions of increasing complexity; the actions are bound with the involved tools and affected objects and are governed by certain goals. We show, how the tool role and the affected-object role of an entity within an action drives the derivation of the action syntax in this grammar and controls recursion, merge and move, the latter being mechanisms that manifest themselves not only in human language, but in human action too.

    2009-01-01

    Full Text Available Abstract Action recognition from video is a problem that has many important applications to human motion analysis. In real-world settings, the viewpoint of the camera cannot always be fixed relative to the subject, so view-invariant action recognition methods are needed. Previous view-invariant methods use multiple cameras in both the training and testing phases of action recognition or require storing many examples of a single action from multiple viewpoints. In this paper, we present a framework for learning a compact representation of primitive actions (e.g., walk, punch, kick, sit that can be used for video obtained from a single camera for simultaneous action recognition and viewpoint estimation. Using our method, which models the low-dimensional structure of these actions relative to viewpoint, we show recognition rates on a publicly available dataset previously only achieved using multiple simultaneous views.

  1. Networks for Collective Action

    CERN Document Server

    Bruggeman, Jeroen

    2016-01-01

    A significant challenge is to explain how people cooperate for public goods. The problem is more difficult for people when their public good and its benefits are unclear at the outset and its timing and costs are uncertain. However, history shows that even under adverse conditions, people can cooperate. As a prelude to cooperation, people can establish (or reinforce) social ties through communication. Consequently, individuals' cognitive states may synchronize, so that they can depend on like-minded people rather than on a situation beyond their control. Whether this succeeds largely depends on the network that is formed (or used), which should also help them to overcome misunderstandings and to synchronize relatively fast. From a well-known model of social influence it is inferred that network patterns with high algebraic connectivity, featuring multiple independent connections, are optimal for collective action.

Instead of smashing protons into protons, it is designed to collide electrons with positrons. Following the publication of its CDR in 2012, the CLIC collaboration entered the project preparation phase - testing its unique technology, making improvements and taking a closer look at the cost of the individual components. This is where the new module comes in. While many of the techniques and technologies neede...

  3. Structure learning in action

    Braun, Daniel A.; Mehring, Carsten; Wolpert, Daniel M.

    2010-01-01

    ‘Learning to learn’ phenomena have been widely investigated in cognition, perception and more recently also in action. During concept learning tasks, for example, it has been suggested that characteristic features are abstracted from a set of examples with the consequence that learning of similar tasks is facilitated—a process termed ‘learning to learn’. From a computational point of view such an extraction of invariants can be regarded as learning of an underlying structure. Here we review the evidence for structure learning as a ‘learning to learn’ mechanism, especially in sensorimotor control where the motor system has to adapt to variable environments. We review studies demonstrating that common features of variable environments are extracted during sensorimotor learning and exploited for efficient adaptation in novel tasks. We conclude that structure learning plays a fundamental role in skill learning and may underlie the unsurpassed flexibility and adaptability of the motor system. PMID:19720086

  4. The Quench Action

    Caux, Jean-Sébastien

    2016-06-01

    We give a pedagogical introduction to the methodology of the Quench Action, which is an effective representation for the calculation of time-dependent expectation values of physical operators following a generic out-of-equilibrium state preparation protocol (for example a quantum quench). The representation, originally introduced in Caux and Essler (2013 Phys. Rev. Lett. 110 257203), is founded on a mixture of exact data for overlaps together with variational reasonings. It is argued to be quite generally valid and thermodynamically exact for arbitrary times after the quench (from short times all the way up to the steady state), and applicable to a wide class of physically relevant observables. Here, we introduce the method and its language, give an overview of some recent results, suggest a roadmap and offer some perspectives on possible future research directions.

  5. Testing Fractional Action Cosmology

    2015-01-01

    The present work deals with a combined test of the so-called Fractional Action Cosmology (FAC) on the example of a specific model obtained by the author earlier. In this model, the effective cosmological term is proportional to the Hubble parameter squared through the so-called kinematic induction. The reason of studying this cosmological model could be explained by its ability to describe two periods of accelerated expansion, that is in agreement with the recent observations and the cosmological inflation paradigm. First of all, we put our model through the theoretical tests that gives a general conception of the influence of the model parameters on its behavior. Then, we obtain some restrictions on the principal parameters of the model, including the fractional index, by means of the observational data. Finally, the cosmography parameters and the observational data compared to the theoretical predictions are presented both analytically and graphically.

    Describes the four near-term strategies selected by the Guam Energy Task Force during action planning workshops conducted in March 2013, and outlines the steps being taken to implement those strategies. Each strategy addresses one of the energy sectors identified in the earlier Guam strategic energy plan as being an essential component of diversifying Guam's fuel sources and reducing fossil energy consumption 20% by 2020. The four energy strategies selected are: (1) expanding public outreach on energy efficiency and conservation, (2) establishing a demand-side management revolving loan program, (3) exploring waste-to-energy options, and (4) influencing the transportation sector via anti-idling legislation, vehicle registration fees, and electric vehicles.

  9. An agenda for action.

    Science.gov (United States)

    1987-01-01

    Participants at the 1985 Maseru Seminar on Another Development for Southern African Development Coordination Conference (SADCC) Countries developed an agenda for action aimed at ending the exploitation of people in the region. Another Development, a concept first introduced into the worldwide debate about economic development in 1975, is based on 5 premises: development should be need-oriented, self-reliant, endogenous, ecologically sound, and based on structural transformations. It should be viewed as an integrated socioeconomic, political, and cultural process. Participants noted that conventional development policies are becoming increasingly incapable of satisfying the basic needs of people in the SADCC region for food, health, housing, education, and employment. The Agenda for Action recognizes that the problems of dependency cannot be solved by the more intensive application of development strategies that created the problems in the first place. Needed, instead, is: 1) effective popular participation in all decision-making processes; 2) the transformation of social structures to facilitate effective participation in decision-making; 3) the full exercise of human rights; 4) the establishment of local, district, and national papers and publishing houses dedicated to the right to be informed; 5) the gearing of agricultural production primarily to the growing of food for domestic markets, with exports limited to surpluses; 6) the production of raw materials for manufactured goods that meet local needs; 7) land reform; 8) the coordinated development of both light and heavy industry and mining, with an emphasis on decentralization of industries to rural areas; 9) the allocation of higher priority to resources for housing; 10) the integration of meaningful productive work into the educational system at every level; 11) the development of an endogenous science and technology base; and 12) the allocation of the resources needed for a primary health care system.

  10. Do not resonate with actions: sentence polarity modulates cortico-spinal excitability during action-related sentence reading.

    Directory of Open Access Journals (Sweden)

    Marco Tullio Liuzza

    Full Text Available BACKGROUND: Theories of embodied language suggest that the motor system is differentially called into action when processing motor-related versus abstract content words or sentences. It has been recently shown that processing negative polarity action-related sentences modulates neural activity of premotor and motor cortices. METHODS AND FINDINGS: We sought to determine whether reading negative polarity sentences brought about differential modulation of cortico-spinal motor excitability depending on processing hand-action related or abstract sentences. Facilitatory paired-pulses Transcranial Magnetic Stimulation (pp-TMS was applied to the primary motor representation of the right-hand and the recorded amplitude of induced motor-evoked potentials (MEP was used to index M1 activity during passive reading of either hand-action related or abstract content sentences presented in both negative and affirmative polarity. Results showed that the cortico-spinal excitability was affected by sentence polarity only in the hand-action related condition. Indeed, in keeping with previous TMS studies, reading positive polarity, hand action-related sentences suppressed cortico-spinal reactivity. This effect was absent when reading hand action-related negative polarity sentences. Moreover, no modulation of cortico-spinal reactivity was associated with either negative or positive polarity abstract sentences. CONCLUSIONS: Our results indicate that grammatical cues prompting motor negation reduce the cortico-spinal suppression associated with affirmative action sentences reading and thus suggest that motor simulative processes underlying the embodiment may involve even syntactic features of language.

  12. Modelling the control of interceptive actions.

    Beek, P J; Dessing, J C; Peper, C E; Bullock, D

    2003-09-29

    In recent years, several phenomenological dynamical models have been formulated that describe how perceptual variables are incorporated in the control of motor variables. We call these short-route models as they do not address how perception-action patterns might be constrained by the dynamical properties of the sensory, neural and musculoskeletal subsystems of the human action system. As an alternative, we advocate a long-route modelling approach in which the dynamics of these subsystems are explicitly addressed and integrated to reproduce interceptive actions. The approach is exemplified through a discussion of a recently developed model for interceptive actions consisting of a neural network architecture for the online generation of motor outflow commands, based on time-to-contact information and information about the relative positions and velocities of hand and ball. This network is shown to be consistent with both behavioural and neurophysiological data. Finally, some problems are discussed with regard to the question of how the motor outflow commands (i.e. the intended movement) might be modulated in view of the musculoskeletal dynamics.

  13. Review: Ernest T. Stringer (2007. Action Research

    Directory of Open Access Journals (Sweden)

    Tobias Denskus

    2008-10-01

    Full Text Available STRINGER's book on action research provides an accessible introduction to conducting participatory inquiries for social change. This general overview of the theoretical foundations of action research and methodological challenges is enriched by practical examples, insights, and exercises that are based on the author's substantial experience as a researcher and practitioner. Students and teachers will find this a valuable resource for teaching and training. However, STRINGER's positive outlook on humanity and communities and his non-confrontational style of action research ignores some of the "darker" sides of power, knowledge, and the difficulties of achieving sustainable social change. The final chapter and substantial appendices have a strong focus on traditional report writing; more alternative case studies on how to communicate action research may have been useful to balance his more conventional project-management approach. Overall, this is a very good introductory volume that can spark ideas, discussions, and (self- reflection on how to better link theory and practice. URN: urn:nbn:de:0114-fqs0901108

  14. An action research approach to curriculum development

    1995-01-01

    Full Text Available Action research has been used in many areas where an understanding of complex social situations has been sought in order to improve the quality of life. Among these are industrial, health and community work settings. Kurt Lewin, often cited as the originator of action research, used the methodology in his work with people affected by post- war social problems. Action research approaches to educational research were adopted in the late 60s and early 70s by the ‘teacher- researcher’ movement in the secondary education sector. This sought to bring the practising classroom teacher into the research process as the most effective person to identify problems and to find solutions.We believe that an action research approach can contribute very positively to activity within the tertiary sector concerned with teaching quality issues, and with national Teaching Quality Assessment initiatives. As 'reflective practitioners', we can achieve greater ownership of the evaluative process by becoming systematically self-assessing, alongside, and feeding into, external assessment processes.

  15. Everyday robotic action: Lessons from human action control

    Roy eDe Kleijn

    2014-03-01

    Full Text Available Robots are increasingly capable of performing everyday human activities such as cooking, cleaning, and doing the laundry. This requires the real-time planning and execution of complex, temporally-extended sequential actions under high degrees of uncertainty, which provides many challenges to traditional approaches to robot action control. We argue that important lessons in this respect can be learned from research on human action control. We provide a brief overview of available psychological insights into this issue and focus on four principles that we think could be particularly beneficial for robot control: the integration of symbolic and subsymbolic planning of action sequences, the integration of feedforward and feedback control, the clustering of complex actions into subcomponents, and the contextualization of action-control structures through goal representations.

  16. The dynamic range of response set activation during action sequencing.

    2017-03-01

    We show that theories of response scheduling for sequential action can be discriminated on the basis of their predictions for the dynamic range of response set activation during sequencing, which refers to the momentary span of activation states for completed and to-be-completed actions in a response set. In particular, theories allow that future actions in a plan are partially activated, but differ with respect to the width of the range, which refers to the number of future actions that are partially activated. Similarly, theories differ on the width of the range for recently completed actions that are assumed to be rapidly deactivated or gradually deactivated in a passive fashion. We validate a new typing task for measuring momentary activation states of actions across a response set during action sequencing. Typists recruited from Amazon Mechanical Turk copied a paragraph by responding to a "go" signal that usually cued the next letter but sometimes cued a near-past or future letter (n-3, -2, -1, 0, +2, +3). The activation states for producing letters across go-signal positions can be inferred from RTs and errors. In general, we found evidence of graded parallel activation for future actions and rapid deactivation of more distal past actions. (PsycINFO Database Record

  17. Perceived positions determine crowding.

    2011-01-01

    Crowding is a fundamental bottleneck in object recognition. In crowding, an object in the periphery becomes unrecognizable when surrounded by clutter or distractor objects. Crowding depends on the positions of target and distractors, both their eccentricity and their relative spacing. In all previous studies, position has been expressed in terms of retinal position. However, in a number of situations retinal and perceived positions can be dissociated. Does retinal or perceived position determine the magnitude of crowding? Here observers performed an orientation judgment on a target Gabor patch surrounded by distractors that drifted toward or away from the target, causing an illusory motion-induced position shift. Distractors in identical physical positions led to worse performance when they drifted towards the target (appearing closer) versus away from the target (appearing further). This difference in crowding corresponded to the difference in perceived positions. Further, the perceptual mislocalization was necessary for the change in crowding, and both the mislocalization and crowding scaled with drift speed. The results show that crowding occurs after perceived positions have been assigned by the visual system. Crowding does not operate in a purely retinal coordinate system; perceived positions need to be taken into account.

    Too often, credible scientific early warning information of increased disaster risk does not result in humanitarian action. With financial resources tilted heavily towards response after a disaster, disaster managers have limited incentive and ability to process complex scientific data, including uncertainties. These incentives are beginning to change, with the advent of several new forecast-based financing systems that provide funding based on a forecast of an extreme event. Given the changing landscape, here we demonstrate a method to select and use appropriate forecasts for specific humanitarian disaster prevention actions, even in a data-scarce location. This action-based forecasting methodology takes into account the parameters of each action, such as action lifetime, when verifying a forecast. Forecasts are linked with action based on an understanding of (1) the magnitude of previous flooding events and (2) the willingness to act "in vain" for specific actions. This is applied in the context of the Uganda Red Cross Society forecast-based financing pilot project, with forecasts from the Global Flood Awareness System (GloFAS). Using this method, we define the "danger level" of flooding, and we select the probabilistic forecast triggers that are appropriate for specific actions. Results from this methodology can be applied globally across hazards and fed into a financing system that ensures that automatic, pre-funded early action will be triggered by forecasts.

  20. Positive criminology in practice.

    Ronel, Natti; Segev, Dana

    2014-11-01

    The discourse regarding offender rehabilitation has been criticized by various scholars who have claimed that reducing negative causes and managing risk will not automatically prompt positive human development and elements that are associated with desistance. Positive criminology is an innovative concept that challenges the common preoccupation with negative elements, by placing emphasis on human encounters and forces of inclusion that are experienced positively by target individuals and that can promote crime desistance. However, as the concept is relatively new, there are still no guiding principles for the practice of positive criminology that could direct research and the criminal justice system. This article attempts to fill that gap by providing principles that could be practiced by criminal justice personnel and examples of different interventions that reflect positive criminology. The article also provides ideological explanations for adopting the concept of positive criminology in practice.

  2. Memories of unethical actions become obfuscated over time.

    Kouchaki, Maryam; Gino, Francesca

    2016-05-31

    Despite our optimistic belief that we would behave honestly when facing the temptation to act unethically, we often cross ethical boundaries. This paper explores one possibility of why people engage in unethical behavior over time by suggesting that their memory for their past unethical actions is impaired. We propose that, after engaging in unethical behavior, individuals' memories of their actions become more obfuscated over time because of the psychological distress and discomfort such misdeeds cause. In nine studies (n = 2,109), we show that engaging in unethical behavior produces changes in memory so that memories of unethical actions gradually become less clear and vivid than memories of ethical actions or other types of actions that are either positive or negative in valence. We term this memory obfuscation of one's unethical acts over time "unethical amnesia." Because of unethical amnesia, people are more likely to act dishonestly repeatedly over time.

In these scenarios, the human directly interacts with objects physically by using....../manipulating them or by, e.g., pointing at them such as in “Give me that…”. To recognize these types of human actions is difficult because (a) they ought to be recognized independent of scene parameters such as viewing direction and (b) the actions are parametric, where the parameters are either object...... tracking and action recognition should be seen as an intertwined problem that is primed by the objects on which the actions are applied.

    Here we introduce reflection positive doubles, a general framework for reflection positivity, covering a wide variety of systems in statistical physics and quantum field theory. These systems may be bosonic, fermionic, or parafermionic in nature. Within the framework of reflection positive doubles, we give necessary and sufficient conditions for reflection positivity. We use a reflection-invariant cone to implement our construction. Our characterization allows for a direct interpretation in terms of coupling constants, making it easy to check in concrete situations. We illustrate our methods with numerous examples.

  9. Is credit for early action credible early action?

    1999-12-01

    Credit for early action as a tool for greenhouse gas emissions reduction is compared with various market instruments as a means of narrowing the gap between projected emssions and those of the Kyoto Protocol. Market instruments work by creating a market price for emissions and use the market to encourage reductions at the lowest price, which is done by placing limits on greenhouse gas emissions and allowing the market to decide where reductions occur, or by imposing a carbon tax or emissions charge. While they can be applied within a sector, they are usually used to encourage reductions throughout the economy or across large sectors. Credit for early action also creates an incentive for emissions reductions throughout the economy or at least across many sectors. Credit for early action tools do not work by either imposing a carbon tax or emissions charge or placing limits on emissions, rather they promise that entities that take action against greenhouse gases prior to the imposition of a carbon tax or emissions limits will receive a credit against future taxes or limits. An overview is provided of the Kyoto Protocol and the rationale for taking early action, and a review is included of the theory and specific proposals for market instruments and credit for early action. A comparative analysis is provided of these approaches by examining their relative efficiency, environmental effectiveness, and impacts on the redistribution of wealth. Credit for early action is viewed as problematic on a number of counts and is seen as an interim strategy for imposition while political support for market instruments develop. The environmental effectiveness of credit for early action is very difficult to predict, and credit for early action programs do not yield the lowest cost emissions reductions. Credit for early action programs will not achieve compliance with the Kyoto Protocol at the lowest cost, and credits for early action will increase the compliance costs for those who

  10. Numbers in Action.

    Rugani, Rosa; Sartori, Luisa

    2016-01-01

    Humans show a remarkable tendency to describe and think of numbers as being placed on a mental number line (MNL), with smaller numbers located on the left and larger ones on the right. Faster responses to small numbers are indeed performed on the left side of space, while responses to large numbers are facilitated on the right side of space (spatial-numerical association of response codes, SNARC effect). This phenomenon is considered the experimental demonstration of the MNL and has been extensively replicated throughout a variety of paradigms. Nevertheless, the majority of previous literature has mainly investigated this effect by means of response times and accuracy, whereas studies considering more subtle and automatic measures such as kinematic parameters are rare (e.g., in a reaching-to-grasp movement, the grip aperture is enlarged in responding to larger numbers than in responding to small numbers). In this brief review we suggest that numerical magnitude can also affect the what and how of action execution (i.e., temporal and spatial components of movement). This evidence could have large implications in the strongly debated issue concerning the effect of experience and culture on the orientation of MNL.

    2009-01-01

    A large number of families and groups of antimicrobial agents are of clinical interest. The mechanisms by which compounds with antibacterial activity inhibit growth or cause bacterial death are varied and depend on the affected targets. The bacterial cell wall-a unique structure in most bacteria that is absent in eukaryotic cells-can be affected in several ways: at different stages of synthesis (fosfomycin, cycloserine) or transport (bacitracin, mureidomycins) of its metabolic precursors, or by a direct action on its structural organization (beta-lactams, glycopeptides). The main drugs affecting the cytoplasmic membrane are polymyxins and daptomycin. Protein synthesis can be blocked by a large variety of compounds that affect any of the phases of this process, including activation (mupirocin), initiation (oxazolidinones, aminoglycosides), binding of the tRNA amino acid complex to ribosomes (tetracyclines, glycylcyclines) and elongation (amphenicols, lincosamides, macrolides, ketolides, streptogramins, fusidic acid). The metabolism of nucleic acids can be altered at the DNA-dependent RNA polymerase or in the process of DNA coiling (quinolones); some compounds affect DNA directly (nitroimidazoles, nitrofurans). Trimethoprim and sulfamides (often used in combination) are examples of antimicrobial agents that block bacterial metabolic pathways. Some compounds are unable to inhibit or kill bacteria in themselves, but can block bacterial mechanisms of resistance, enhancing the activity of other antimicrobials administered in combination. Among this group of agents, only certain beta-lactamase inhibitors are currently in clinical use.

Education should respect the basic laws of the develop and progress. Curiosity is the engine of achievement and children spontaneously and happily learn only if they get interested, if teacher wake up and stimulate their creativity and individuality. We would like to present classes that are realized as thematic teaching with several subjects involved: chemistry, geography, math, art and biology. Classes were organized for students at age from 10 to 13 years, every month during autumn and winter 2015. Better students identified themselves as teachers and presented peer education .Teachers were monitoring the process of teaching and help to develop links between younger and older students, where older students were educators to younger students. Also one student with special needs was involved in this activities and was supported by other students during the workshops The benefit from this project will be represented with evaluation marks. Evaluation table shows that group of ten students(age 10 to13 years) which are selected in October as children with lack of motivation for learning, got better marks, at the end of January , then they had it in the beginning of the semester.

  15. Nonclassical Vitamin D Actions

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available It is becoming increasingly clear that vitamin D has a broad range of actions in the human body. Besides its well-known effects on calcium/phosphate homeostasis, vitamin D influences muscle function, cardiovascular homeostasis, nervous function, and the immune response. Vitamin D deficiency/insufficiency has been associated with muscle weakness and a high incidence of various chronic diseases such as cardiovascular disease, cancer, multiple sclerosis, and type 1 and 2 diabetes. Most importantly, low vitamin D status has been found to be an independent predictor of all-cause mortality. Several recent randomized controlled trials support the assumption that vitamin D can improve muscle strength, glucose homeostasis, and cardiovascular risk markers. In addition, vitamin D may reduce cancer incidence and elevated blood pressure. Since the prevalence of vitamin D deficiency/insufficiency is high throughout the world, there is a need to improve vitamin D status in the general adult population. However, the currently recommended daily vitamin D intake of 5–15 µg is too low to achieve an adequate vitamin D status in individuals with only modest skin synthesis. Thus, there is a need to recommend a vitamin D intake that is effective for achieving adequate circulating 25-hydroxyvitamin D concentrations (>75 nmol/L.

    Action-specific effects on perception are apparent in terrestrial environments. For example, targets that require more effort to walk, jump, or throw to look farther away than when the targets require less effort. Here, we examined whether action-specific effects would generalize to an underwater environment. Instead, perception might be geometrically precise, rather than action-specific, in an environment that is novel from an evolutionary perspective. We manipulated ease to swim by giving p...

    2009-01-01

    We apply the laws of human gait vertical ground reaction force and discover the existence of the phenomenon of least action principle in gait. Using a capacitive mat transducer system, we obtain the variations of human gait vertical ground reaction force and establish a structure equation for the resultant of such a force. Defining the deviation of vertical force as an action function, we observe from our gait optimization analysis the least action principle at half of the stride time. We develop an evaluation index of mechanical energy consumption based upon the least action principle in gait. We conclude that these observations can be employed to enhance the accountability of gait evaluation.

  19. Perfect Actions for Scalar Theories

    CERN Document Server

    Bietenholz, W

    1998-01-01

    We construct an optimally local perfect lattice action for free scalars of arbitrary mass, and truncate its couplings to a unit hypercube. Spectral and thermodynamic properties of this ``hypercube scalar'' are drastically improved compared to the standard action. We also discuss new variants of perfect actions, using anisotropic of triangular lattices, or applying new types of RGTs. Finally we add a $\\lambda \\phi^{4}$ term and address perfect lattice perturbation theory. We report on a lattice action for the anharmonic oscillator, which is perfect to $O(\\lambda)$.

  20. Softness and Amplitudes' Positivity for Spinning Particles

    CERN Document Server

    Bellazzini, Brando

    2016-01-01

    We derive positivity bounds for scattering amplitudes of particles with arbitrary spin using unitarity, analyticity and crossing symmetry. The bounds imply the positivity of certain low-energy coefficients of the effective action that controls the dynamics of the light degrees of freedom. We show that low-energy amplitudes strictly softer than $O(p^4)$ do not admit unitary ultraviolet completions unless the theory is free. This enforces a bound on the energy growth of scattering amplitudes in the region of validity of the effective theory. We discuss explicit examples including the Goldstino from spontaneous supersymmetry breaking, and the theory of a spin-1/2 fermion with a shift symmetry.

    This study aimed to characterize the manifestations of clinical symptoms and signs, primary rheumatic diseases, and other autoantibodies in pediatric patients with positive anti-SSA and/or anti-SSB antibodies. Subjects under age 18 with positive anti-SSA and/or anti-SSB antibodies were screened and enrolled in a tertiary hospital in Taiwan. Data were collected via medical records,including age, gender, onset of the primary rheumatic disease, clinical symptoms and signs, and the medication used. Schirmer test for Sjögren's syndrome (SS) screening was performed in all enrolled patients. Among twenty enrolled subjects, seventeen of them had systemic lupus erythematosus; four of them were diagnosed as SS with positive Schirmer test. In addition to antinuclear antibodies and anti-DNA antibodies, other common autoantibodies were anti-RNP antibodies (50 %) and anti-Sm antibodies(30 %). The most common symptoms were arthritis (60 %)followed by malar rash (40 %). In conclusion, we observed that a low proportion of childhood SS (4/20) exists in our patients with positive SSA and/or anti-SSB antibodies. It is suggested that clinicians should focus more on the clinical symptoms in these patients, rather than undertaking invasive diagnostic interventions to rule out Sjögren's syndrome.

    We study localization of atomic position when a three-level atom interacts with a quantized standing-wave field in the Ramsey interferometer setup. Both the field quadrature amplitude and the atomic internal state are measured to obtain the atomic position information. It is found that this dual measurement scheme produces an interference pattern superimposed on a diffraction-like pattern in the atomic position distribution, where the former pattern originates from the state-selective measurement and the latter from the field measurement. The present scheme results in a better resolution in the position localization than the field-alone measurement schemes. We also discuss the measurement-correlated mechanical action of the standing-wave field on the atom in the light of Popper's test.

  8. Climate Literacy: Springboard to Action

    Research indicates that the public views zoos and aquariums as reliable and trusted sources for information on conservation (Ocean Project, 2009). The Aquarium of the Pacific is using NOAA's Science on a Sphere (SOS)° and linked flat screens to convey climate concepts to the public and serve as a model for how aquariums can promote climate literacy. The Ocean Science Center houses the SOS and is designed to immerse our visitors in an experience that extends from the sphere, to our live animals, and to our public programming. The first SOS exhibit, the sea level rise story, opened as the cornerstone of an aquarium-wide climate literacy strategy. Large panels next to the SOS prompts visitors to pledge actions to reduce their personal carbon footprint. The exhibit objectives were to provide a visual presentation that conveys a dramatic story about sea level rise, and to engage the audience in confronting the impact of sea level rise, and the local implications. The Aquarium utilized Yale's Six Americas survey instrument during summer 2010 to measure our audience interpretations of and responses to climate change. The survey showed that 78% of visitors categorized themselves as either alarmed or concerned about climate change, greater than the national average. Thus our climate literacy programs do not focus on convincing visitors of climate change and its causes, but on encouraging adaptive responses to varying scenarios. University of California, Berkeley, Lawrence Hall of Science Center for Research Evaluation and Assessment (REA) conducted a pre-opening evaluation of the exhibit's impact. The participants, 58% of whom were families with children, did not want to know more about climate change, but wanted tangible activities they could engage in to mitigate human induced effects, and more details about the impact of climate change on marine animals. REA stated that, "the sea level rise programs (both facilitated and non-facilitated) are well positioned to be

Small molecules of molecular targeted agents for lung cancer with actionable mutations were reported to be palliated for symptoms caused by choroidal metastasis. Visual disturbance by choroidal metastasis significantly decreases quality of life during the patient’s remaining lifespan; therefore, radiotherapy or laser photocoagulation is proposed with consensus. However, improvement in survival with matched molecular targeted agents for oncogenic driver mutations reminds us to also be concerned with late treatment toxicities. A 30-year-old female patient previously treated with crizotinib harboring ALK rearranged non-small cell lung cancer complained of visual disturbance, fever, and bone pains undergoing anti-PD-1 antibody treatment. A decreased proportion of ALK fusion was demonstrated by fluorescence in situ hybridization in liver metastasis compared to the primary site in a chemo-naïve state. She was diagnosed with low vision, choroidal metastasis and retinal detachment. Therefore, she started alectinib treatment and both her ocular and systemic symptoms were palliated in a week. Later, she temporarily discontinued alectinib because of skin rash although the choroidal metastasis and retinal detachment resolved and she regained low vision completely at 2 weeks. She obtained partial response with alectinib for more than 5 months after recovering from skin rash. Keywords: lung cancer, ALK rearrangement, alectinib, choroidal metastasis, molecular targeted

  10. POSITIONING STRATEGIES DEVELOPMENT

    2014-07-01

    Full Text Available The positioning strategy has suffered serious changes in the last few decades, being influenced by the rapid development of competition and the growing focus on specific traits belonging to the market, to the consumer or to the product. The purpose of this paper is to present the developments of theoretical positioning strategies and the orientation from more simple, product oriented strategies, to ones more oriented towards the client and with a briefer period of time. The world is moving in a much faster pace than in the past, thanks to communication development so companies are obliged to adopt more specific strategies in order for them to be effective. This essay represents a literary review presenting a documentary research within the scientific articles and strategy and positioning books. The paper begins with the analysis of company strategies and the marketing strategies in general. The first author to group the product positioning strategies is Porter with his three generic strategies. Following the development of brands and because of the lack of competitiveness in the simple generic positioning strategies, this paper has also presented the newer positioning strategies proposed by Kotler, Treacy & Wiersema, and also more complex ones such as Bowman's Strategy Clock and Blankson and Kalafatis positioning strategy based on the type of the consumer. The fast expansion of local brands in all categories has led to mistakes in positioning strategies, categories also presented in the current essay. The results of this study show that new positioning strategies are more and more based on the consumer and market segments and on the product specification - which have also evolved in the last decades. Adaptability to fast changes in the competitive market will represent the future positioning strategies.

    2014-11-01

    This article examines the use of action learning sets in a leadership module delivered by a university in south east England. An evaluation research study was undertaking using survey method to evaluate student engagement with action learning sets, and their value, impact and sustainability. Data were collected through a questionnaire with a mix of Likert-style and open-ended questions and qualitative and quantitative data analysis was undertaken. Findings show that engagement in the action learning sets was very high. Action learning sets also had a positive impact on the development of leadership knowledge and skills and are highly valued by participants. It is likely that they would be sustainable as the majority would recommend action learning to colleagues and would consider taking another module that used action learning sets. When compared to existing literature on action learning, this study offers new insights as there is little empirical literature on student engagement with action learning sets and even less on value and sustainability.

  13. Modeling the value of strategic actions in the superior colliculus

    Directory of Open Access Journals (Sweden)

    Dhushan Thevarajah

    2010-02-01

    Full Text Available In learning models of strategic game play, an agent constructs a valuation (action value over possible future choices as a function of past actions and rewards. Choices are then stochastic functions of these action values. Our goal is to uncover a neural signal that correlates with the action value posited by behavioral learning models. We measured activity from neurons in the superior colliculus (SC, a midbrain region involved in planning saccadic eye movements, in monkeys while they performed two saccade tasks. In the strategic task, monkeys competed against a computer in a saccade version of the mixed-strategy game “matching-pennies”. In the instructed task, stochastic saccades were elicited through explicit instruction rather than free choices. In both tasks, neuronal activity and behavior were shaped by past actions and rewards with more recent events exerting a larger influence. Further, SC activity predicted upcoming choices during the strategic task and upcoming reaction times during the instructed task. Finally, we found that neuronal activity in both tasks correlated with an established learning model, the Experience Weighted Attraction model of action valuation (Ho, Camerer, and Chong, 2007. Collectively, our results provide evidence that action values hypothesized by learning models are represented in the motor planning regions of the brain in a manner that could be used to select strategic actions.
