    The two main purposes of this work are (1) to determine the penumbra characteristics for 125I eye plaque and the relative influence of the plaque and eye-air interface on the dose distribution, and (2) to initiate development of a treatment planning algorithm for clinical dose calculations. Dose was measured in a newly designed solid water eye phantom for an 125I (6711) seed at the center of a 20 mm COMS eye plaque using thermoluminescent dosimeter (TLD) "cubes" and "minichips" inside and outside the eye, in the longitudinal and transverse central planes. TLD cubes were used in most locations, except for short distances from the seed and in the penumbra region. In the presence of both the plaque and the eye-air interface, the dose along the central axis was found to be reduced by 10% at 1 cm and up to 20% at 2.5 cm, relative to the bulk homogeneous phantom case. In addition, the overall dose reduction was greater for larger off-axis coordinates at a given depth. The penumbra characteristics due to the lip collimation were quantified, particularly the dependence of penumbra center and width on depth. Only small differences were observed between the profiles in the transverse and longitudinal planes. In the bulk geometry (without the eye-air interface), the dose reduction due to the presence of the plaque alone was found to be 7% at a depth of 2.5 cm. The additional reduction of 13% observed, with the presence of eye-air interface (20% combined), can be attributed to the lack of backscattering from the air in front of the eye. The dose-reduction effect due to the anterior air interface alone became unnoticeable at a depth of 1.1 cm (1.5 cm from the eye-air interface). An analytic fit to measured data was developed for clinical dose calculations for a centrally loaded seed. The central axis values of the dose rates multiplied by distance squared, Dr2, were fitted with a double exponential function of depth. The off-axis profile of Dr2, at a given depth, was

    Presenting characteristics of bacterial corneal ulcers may suggest particular causative organisms, helping to guide treatment decisions before cultures become available. In this study, we analyze the association between presentation demographic and clinical characteristics, using data collected as part of a randomized, controlled clinical trial. Data for this study were collected as part of the Steroids for Corneal Ulcers Trial, a randomized, placebo-controlled, double-masked trial. All patients had a culture-proven bacterial corneal ulcer. Patient history, clinical examination, and photography were performed in a standardized fashion at enrollment. Analysis of variance or Fisher's exact test was used to compare characteristics by organism. Univariate logistic regression was used to analyze predictors of the most common organisms. Five hundred patients were enrolled in the trial, of whom 488 were included in this analysis. The most common organism was Streptococcus pneumoniae (N = 248, 51 %) followed by Pseudomonas aeruginosa (N = 110, 23 %). Compared to other organisms, P. aeruginosa was significantly associated with a larger baseline infiltrate/scar size [odds ratio (OR) 1.6, 95 % confidence interval (CI) 1.4-1.8] and deeper infiltrate (OR 2.4, 95 % CI 1.5-3.8). S. pneumoniae was significantly associated with a smaller baseline infiltrate/scar size (OR 0.8, 95 % CI 0.7-0.9) and dacryocystitis (OR 7.3, 95 % CI 4.1-13.3). Nocardia spp. were significantly associated with longer duration of symptoms prior to presentation (OR 1.4, 95 % CI 1.2-1.6), more shallow infiltrate (OR 0.3, 95 % CI 0.2-0.5), and better baseline visual acuity (OR 0.4, 95 % CI 0.2-0.65). Staphylococcus spp. were less likely to be central in location (OR 0.16, 95 % CI 0.08-0.3). Baseline characteristics of bacterial ulcers may suggest the likely etiology and guide early management.

    In a series of three studies, characteristics of novel figurative phrases were compared with those of established idioms. Studies 1 and 2 found that certain correlations were found to be strong and in one direction for familiar idioms and comparably strong but in the opposite direction for novel figurative phrases, with the correlations for less familiar idioms usually falling partway between these extremes. Study 2 also noted that written or auditory presentation had minimal effects on characteristic ratings. In Study 3 the correlations among characteristics stayed relatively constant for familiar idioms after one, three, or six presentations, but for the novel figurative phrases, after multiple presentations the correlations changed in the direction of the established idioms.

    The TED (Technology, Entertainment, Design) conference and associated website of recorded conference presentations (TED Talks) is a highly successful disseminator of science-related videos, claiming over a billion online views. Although hundreds of scientists have presented at TED, little information is available regarding the presenters, their academic credentials, and the impact of TED Talks on the general population. This article uses bibliometric and webometric techniques to gather data on the characteristics of TED presenters and videos and analyze the relationship between these characteristics and the subsequent impact of the videos. The results show that the presenters were predominately male and non-academics. Male-authored videos were more popular and more liked when viewed on YouTube. Videos by academic presenters were more commented on than videos by others and were more liked on YouTube, although there was little difference in how frequently they were viewed. The majority of academic presenters were senior faculty, males, from United States-based institutions, were visible online, and were cited more frequently than average for their field. However, giving a TED presentation appeared to have no impact on the number of citations subsequently received by an academic, suggesting that although TED popularizes research, it may not promote the work of scientists within the academic community.

    Investigate the epidemiological characteristics of pediatric epistaxis in the emergency department setting. Cross-sectional study using national databases. Children (age epistaxis were extracted from the State Emergency Department Databases for New York, Florida, Iowa, and California for the calendar year 2010. Associated diagnoses, procedures, encounter characteristics, and demographic data were examined. There were 18,745 cases of pediatric epistaxis (mean age 7.54 years, 57.4% male). Overall, 6.9% of patients underwent procedures to control epistaxis, of which 93.5% had simple anterior epistaxis control. The distribution of pediatric epistaxis was highest in spring and summer months (p epistaxis presentations (38.8%, p epistaxis control procedure performed (p epistaxis control procedure (p epistaxis control procedure compared to those of minority backgrounds (p epistaxis are uninvolved cases that do not require procedural intervention. The overrepresentation of low socioeconomic status patients may suggest an overutilization of emergency services for minor cases of epistaxis, and perhaps a lack of access to primary care providers. This is the first study to evaluate racial and socioeconomic factors in relationship to pediatric epistaxis. Further investigation is needed to better elucidate these potential disparities.

    Full Text Available Background: The aim of our study was to investigate the clinical and histopathological characteristics of cutaneous leishmaniasis (CL in the city of Sanliurfa in Turkey, where Syrian refugees also reside. Materials and Methods: At the Harran University Hospital outpatient clinics between 2012 and 2013, 54 CL cases, including 24 Syrian patients, underwent punch biopsy of the skin and/or a touch imprint. Patients in whom leishmania parasites were detected were included in the study. The clinical and histopathological data of the patients were obtained by a review of the patients′ medical records. All the slides of each patient were re-evaluated histopathologically. Results: Fifty-four cases (mean age; 17 ± 12 years, consisting of 32 males (59.3% and 22 females (40.7%, were examined. The most common site of involvement was the face (63%. The most common presentation was noduloulcerative lesions (57.4%. Histopathologically, the majority of the cases exhibited hyperkeratosis, follicular plugging of the epidermis, chronic inflammatory infiltration, leishmania amastigotes and non-caseating granulomatous inflammation in the dermis. Conclusion: CL presents with a wide spectrum of expression, both clinically and histologically, and may mimic other inflammatory and neoplastic diseases. The diagnosis of CL relies on the identification of leishmania amastigotes in either a direct smear of the lesion or in a tissue section.

    a) to examine the demographic and clinical characteristics of repeat-presentations to an adolescent urgent psychiatric clinic, and b) to compare them with single-time presentation. This 18-month retrospective study compared repeat-presenters to age and gender matched single-time presenters. Demographic variables included age gender and ethnicity. Clinical variables included reason for referral, family history, diagnosis, recommendations and compliance. Data were analyzed using descriptive statistics, McNemar's Chi-square tests for matched pairs, and conditional logistic regression. Of 624 assessments 24% (N=151) were repeat-presentations. Compared with single-presentation, repeat-presentation group had a higher proportion of Aboriginal youth (X2 (1) = 108.28 p presentation group had higher odds of past hospital admission (OR: 3.50, p presentations for urgent psychiatric consultation constitute a quarter of referrals to the urgent psychiatric clinic. Identifying and addressing factors that contribute to repeat-presentations may, assist in improving treatment compliance by ensuring focused interventions and service delivery for these youth. In turn, this will improve access to the limited urgent services for other youth.

    Background . Laparoendoscopic rendezvous (LERV) technique is emerging as an attractive treatment option for concomitant cholecystocholedocholithiasis. In this paper, we report our experience in performing the LERV technique in patients with unusual presentations in terms of anatomical difficulty, pregnancy, multiple comorbid diseases, and postlaparotomy. We aim to highlight the effectiveness of the LERV technique in some clinical situations where conventional methods would fail or carry high risks in adequately managing concomitant cholecystocholedocholithiasis. Methods . Four patients diagnosed to have concomitant cholecystocholedocholithiasis with associated difficult presentation or comorbid diseases were treated using the LERV technique. One patient presented with difficult anatomy where ERCP failed at initial attempts. Another patient was pregnant (first trimester). A third patient had complex comorbid diseases (bronchial asthma, hypertension, congestive heart failure, and end-stage renal disease on regular hemodialysis). A fourth patient had previous laparotomy and sigmoidectomy for diverticular disease and had severe hospital phobia. Results . All patients tolerated the LERV technique very well; no intraoperative occurrence was reported. The mean operative time was 86.3 ± 17.2 minutes; mean time of the endoscopic part was 29.4 ± 3.57 minutes. The mean blood loss was 44.3 ± 18.2 mL (range 20-85). Residual stone, postoperative complications, postoperative morbidity, and postoperative mortality were 0 (0%). Postoperative short hospital stay was reported in all patients, average 3 days (range 2-4). Conclusion . LERV procedure is a safe and effective treatment option for the management of concomitant cholecystocholedocholithiasis, even in difficult situations where other methods would fail or carry high risks, or in patients presenting with severe comorbid diseases or pregnancy. This procedure may emerge as an attractive alternative option for high

    We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

    Acute pancreatitis is a rare initial presentation of non-Hodgkin lymphoma with few reported cases described in older adults and even fewer in children. MRI features of Burkitt lymphoma of the pancreas are sparse in the radiologic literature. We present a 6-year-old boy who presented with pancreatitis and obstructive jaundice, which was the result of Burkitt lymphoma of the pancreas. The imaging findings of pancreatic involvement of Burkitt lymphoma on MRI are discussed and the contributory role of the radiologist in guiding the appropriate clinical work-up of this disease is highlighted.

Using today's available 3D technologies a virtual museum is no longer just a presentation of collections on the Internet or a virtual tour of an exhibition using panoramic photography. On one hand, a virtual museum should enhance a museum visitor's experience by providing access to additional materials for review and knowledge deepening either before or after the real visit. On the other hand, a virtual museum should also be used as teaching material in the context of museum education. The laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has developed a virtual museum (VM) of the museum "Alt-Segeberger Bürgerhaus", a historic town house. The VM offers two options for visitors wishing to explore the museum without travelling to the city of Bad Segeberg, Schleswig-Holstein, Germany. Option a, an interactive computer-based, tour for visitors to explore the exhibition and to collect information of interest or option b, to immerse into virtual reality in 3D with the HTC Vive Virtual Reality System.

    A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease. (author)

    We reviewed 13 cases of patients with unruptured dissections of the vertebral artery who were treated at our hospital after presenting with headaches. We identified 13 patients who had headache alone at the time of onset and who were diagnosed as having vertebral artery dissection using three-dimensional CT, MRI, MR angiography (MRA), or angiography from November 2007 to October 2009. Primary radiographic investigations showed the 'pearl and string' sign in two cases, dilatation in eight, and the string sign alone in three cases. Following initial conservative treatment, 11 cases exhibited radiographic improvement, but two cases underwent surgical treatment because of progressive vertebral artery dissection. A definitive diagnosis was made using primary investigations in nine cases and dynamic changes on radiographic investigations in four cases. The headache was located posteriorly in all cases, but some patients had mild headaches. Clinicians need to be aware of the possibility of vertebral artery dissection even if the headache is mild at onset. Radiographic investigations are important for a definitive diagnosis and in deciding whether to intervene surgically. (author)

    OBJECTIVE: To summarize Cochrane reviews of acupuncture for neurological disorders, and characteristics of included reviews and studies.DATA SOURCES: A computer-based online search of the Cochrane Library (Issue 7 of 12, July 2010) was performed with the key word "acupuncture" and systematic evaluations for acupuncture for neurological disorders were screened.STUDY SELECTION: Systematic reviews on acupuncture in the treatment of neurological disorders were included, and the characteristics of these reviews were analyzed based on methods recommended by the Cochrane collaboration.MAIN OUTCOME MEASURES: Basic characteristics, methodological quality, main reasons for excluding trials, results and conclusions of Cochrane reviews were assessed.RESULTS: A total of 18 Cochrane systematic reviews were included, including 13 completed reviews and five research protocols. The 13 completed reviews involved 111 randomized controlled trials, including 43 trials (38.7%) conducted in China, 47 trials (42.3%) using sham-acupuncture or placebo as control, 15 trials (13.5%) with relatively high quality, 91 trials (81.9%) reporting data on follow-up. Primary outcomes used in the Cochrane reviews were reported by 65 trials (58.6%), and adverse events were reported in 11 trials (9.9%). Two hundred and eighty three trials were excluded. Two reviews on headache suggested that acupuncture is a valuable non-drug treatment for patients with chronic or recurrent headache, and has better curative effects on migraine compared with preventative drug treatment. CONCLUSION: Of the Cochrane reviews on acupuncture in the treatment of neurological disorders, two reviews evaluating the efficacy of acupuncture in treating headaches drew positive conculsions, while other reviews did not obtain positive conclusions due to a small sample size or low methodological quality. The methodological quality of acupuncture trials needs further improvement.

However, continuously cloudy weather or rainfall, especially during the grain-filling stage, induces a significant loss in yield and results in poor grain quality. Stress caused by low light often creates severe meteorological disasters in some rice-growing regions worldwide. This review was based on our previous research and related research regarding the effects of low light on rice growth, yield and quality as well as the formation of grain, and mainly reviewed the physiological metabolism of rice plants, including characteristics of photosynthesis, activities of antioxidant enzymes in rice leaves and key enzymes involved in starch synthesis in grains, as well as the translocations of carbohydrate and nitrogen. These characteristics include various grain yield and rice quality components (milling and appearance as well as cooking, eating and nutritional qualities under different rates of shading imposed at the vegetative or reproductive stages of rice plants. Furthermore, we discussed why grain yield and quality are reduced under the low light environment. Next, we summarized the need for future research that emphasizes methods can effectively improve rice grain yield and quality under low light stress. These research findings can provide a beneficial reference for rice cultivation management and breeding program in low light environments.

    During the two major earthquakes occurred in Kumamoto prefecture, at 21:26 on 14 April, 2016 (Mw 6.2, GCMT), and at 1:25 on 16 April, 2016 (Mw7.0, GCMT), a large number of strong ground motions were recorded, including those very close to the surface fault. In this study, we will discuss the attenuation characteristics of strong ground motions observed during the earthquakes. The data used in this study are mainly observed by K-NET, KiK-net, Osaka University, JMA and Kumamoto prefecture. The 5% damped acceleration response spectra (GMRotI50) are calculated based on the method proposed by Boore et al. (2006). PGA and PGV is defined as the larger one among the PGAs and PGVs of two horizontal components. The PGA, PGV, and GMRotI50 data were corrected to the bedrock with Vs of 1.5km/s based on the method proposed by Si et al. (2016) using the average shear wave velocity (Vs30) and the thickness of sediments over the bedrock. The thickness is estimated based on the velocity structure model provided by J-SHIS. We use a source model proposed by Koketsu et al. (2016) to calculate the fault distance and the median distance (MED) which defined as the closest distance from a station to the median line of the fault plane (Si et al., 2014). We compared the observed PGAs, PGVs, and GMRotI50 with the GMPEs developed in Japan using MED (Si et al., 2014). The predictions by the GMPEs are generally consistent with the observations during the two Kumamoto earthquakes. The results of the comparison also indicated that, (1) strong motion records from the earthquake on April 14th are generally consistent with the predictions by GMPE, however, at the periods of 0.5 to 2 seconds, several records close to the fault plane show larger amplitudes than the predictions by GMPE, including the KiK-net station Mashiki (KMMH16); (2) for the earthquake on April 16, the PGAs and GMRotI50 at periods from 0.1s to 0.4s with short distance from the fault plane are slightly smaller than the predictions by

    This paper presents a novel techno-economic optimization model for assessing the effectiveness of CO2 mitigation options for the electricity generation sub-sector that includes renewable energy generation. The optimization problem was formulated as a MINLP model using the GAMS modeling system. The model seeks the minimization of the power generation costs under CO2 emission constraints by dispatching power from low CO2 emission-intensity units. The model considers the detailed operation of the electricity system to effectively assess the performance of GHG mitigation strategies and integrates load balancing, carbon capture and carbon taxes as methods for reducing CO2 emissions. Two case studies are discussed to analyze the benefits and challenges of the CO2 reduction methods in the electricity system. The proposed mitigations options would not only benefit the environment, but they will as well improve the marginal cost of producing energy which represents an advantage for stakeholders.

    Delayed arrival to a primary percutaneous coronary intervention (PPCI)-capable hospital following ST-elevation myocardial infarction (STEMI) is associated with poorer outcome. The influence of patient characteristics on delayed presentation during STEMI is unknown. This was a retrospective observational study. Patients presenting for PPCI from March 2008 to November 2011 in the north of England (Northumbria, Tyne and Wear) were included. The outcomes were self-presentation to a non-PPCI-capable hospital, symptom to first medical contact (STFMC) time, total ischaemic time and mortality during follow-up. STEMI patients included numbered 2297; 619 (26.9%) patients self-presented to a non-PPCI-capable hospital. STFMC of >30 min and total ischaemic time of >180 min was present in 1521 (70.7%) and 999 (44.9%) cases, respectively. Self-presentation was the strongest predictor of prolonged total ischaemic time (odds ratio, OR (95% confidence interval, CI): 5.05 (3.99-6.39)). Married patients (OR 1.38 (1.10-1.74)) and patients living closest to an Emergency Room self-presented more commonly (driving time (vs. ≤10 min) 11-20 min OR 0.66 (0.52-0.83), >20 minutes OR 0.46 (0.33-0.64). Unmarried females waited longest to call for help (OR vs. married males 1.89 (1.29-2.78) and experienced longer total ischaemic times (OR 1.51 (1.10-2.07)). Married patients had a borderline association with lower mortality (hazard ratio 0.75 (0.53-1.05), p=0.09). Unmarried female patients had the longest treatment delays. Married patients and those living closer to an Emergency Room self-present more frequently. Early and exclusive use of the ambulance service may reduce treatment delay and improve STEMI outcome. © The European Society of Cardiology 2014.

    Full Text Available Introduction: Community health clinics (CHCs are an opportune setting to identify and treat substance misuse. This study assessed the characteristics of patients who presented to a CHC with substance misuse. Methods: Personnel at a large CHC administered a 5-question screener to patients between June 3, 2014, and January 15, 2016, to assess past 3-month alcohol use, prescription opioid misuse, or illicit drug use. We stratified screen-positive patients into 4 diagnostic groups: (1 probable alcohol use disorder (AUD and no comorbid opioid use disorder (OUD; (2 probable heroin use disorder; (3 probable prescription OUD, with or without comorbid AUD; and (4 no probable substance use disorder. We describe substance use and mental health characteristics of screen-positive patients and compare the characteristics of patients in the diagnostic groups. Results: Compared to the clinic population, screen-positive patients (N = 733 included more males ( P < .0001 and had a higher prevalence of probable bipolar disorder ( P < .0001 and schizophrenia ( P < .0001. Eighty-seven percent of screen-positive patients had probable AUD or OUD; only 7% were currently receiving substance use treatment. The prescription opioid and heroin groups had higher rates of past bipolar disorder and consequences of mental health conditions than the alcohol only or no diagnosis groups ( P < .0001. Conclusions: Patients presenting to CHCs who screen positive for alcohol or opioid misuse have a high likelihood of having an AUD or OUD, with or without a comorbid serious mental illness. Community health clinics offering substance use treatment may be an important resource for addressing unmet need for substance use treatment and comorbid mental illness.

    the alpha k-3 peptide binds slightly less well. These combined data, suggesting that class II-derived peptides can bind to MHC class II molecules, including the autologous molecule from which they are derived, have important implications for the molecular basis of alloreactivity and autoreactivity. Further...... found in the first and third polymorphic regions (PMR) of the A alpha k chain (alpha k-1 and alpha k-3) were capable of inhibiting the presentation of three different HEL-derived peptide antigens to their appropriate T cells. In addition, the alpha k-1 peptide inhibited the presentation of the OVA(323......-339) immunodominant peptide to the I-Ad-restricted T cell hybridomas specific for it. Prepulsing experiments demonstrated that the PMR peptides were interacting with the APC and not with the T cell hybridomas. These observations were confirmed and extended by the demonstration that the alpha k-1 and alpha k-3...

    Clinical presentation of hypopituitarism in the neonate may be variable, ranging from absent to severe nonspecific symptoms and may be life-threatening in patients with adrenocorticotropic hormone deficiency. The LIM homeobox gene 4 (LHX4) transcription factor regulates early embryonic development of the anterior pituitary gland. Autosomal dominant mutations in LHX4 cause congenital hypopituitarism with variable combined pituitary hormone deficiency (CPHD). We report on a neonate with unexplained heart failure and minor physical anomalies, suggesting a midline defect. She was diagnosed with complete CPHD. Cardiac function was rescued by replacement with hydrocortisone and thyroxine; hypoglycaemia stopped under growth hormone therapy. Magnetic resonance imaging revealed a dysgenetic pituitary gland suggesting an early developmental defect. Array comparative genomic hybridization showed a maternally inherited 1.5-megabase microdeletion in 1q25.2q25.3, including the LHX4 gene. Haploinsufficiency of LHX4 likely explains the predominant pituitary phenotype in the proposita and we suggest variable intrafamilial penetrance of the inherited microdeletion. To the best of our knowledge, we are the first to report on heart failure as a rare nonspecific symptom of treatable CPHD in the newborn. Variably penetrant pituitary insufficiency, including this severe and atypical presentation, can be correlated with LHX4 insufficiency and highlights the role of LHX4 for pituitary development.

    Full Text Available Abstract Background In 2000, the national cancer plan for England created 34 cancer networks, new organisational structures to coordinate services across populations varying between a half and three million people. We investigated the availability of data sets reflecting measures of structure, process and outcome that could be used to support network management. Methods We investigated the properties of national data sets relating to four common cancers – breast, colorectal, lung and prostate. We reviewed the availability and completeness of these data sets, identified leading items within each set and put them into tables of the 34 cancer networks. We also investigated methods of presentation. Results The Acute Hospitals Portfolio and the Cancer Standards Peer Review recorded structural characteristics at hospital and cancer service level. Process measures included Hospital Episode Statistics, recording admissions, and Hospital Waiting-List data. Patient outcome measures included the National Survey of Patient Satisfaction for cancer, and cancer survival, drawn from cancer registration. Data were drawn together to provide an exemplar indicator set a single network, and methods of graphical presentation were considered. Conclusion While not as yet used together in practice, comparative indicators are available within the National Health Service in England for use in performance assessment by cancer networks.

    The conventional PSA techniques cannot adequately evaluate all events. The conventional PSA models usually focus on single internal events such as DBAs, the external hazards such as fire, seismic. However, the Fukushima accident of Japan in 2011 reveals that very rare event is necessary to be considered in the PSA model to prevent the radioactive release to environment caused by poor treatment based on lack of the information, and to improve the emergency operation procedure. Especially, the results from PSA can be used to decision making for regulators. Moreover, designers can consider the weakness of plant safety based on the quantified results and understand accident sequence based on human actions and system availability. This study is for PSA modeling of combined accidents including total loss of feedwater (TLOFW) accident. The TLOFW accident is a representative accident involving the failure of cooling through secondary side. If the amount of heat transfer is not enough due to the failure of secondary side, the heat will be accumulated to the primary side by continuous core decay heat. Transients with loss of feedwater include total loss of feedwater accident, loss of condenser vacuum accident, and closure of all MSIVs. When residual heat removal by the secondary side is terminated, the safety injection into the RCS with direct primary depressurization would provide alternative heat removal. This operation is called feed and bleed (F and B) operation. Combined accidents including TLOFW accident are very rare event and partially considered in conventional PSA model. Since the necessity of F and B operation is related to plant conditions, the PSA modeling for combined accidents including TLOFW accident is necessary to identify the design and operational vulnerabilities.The PSA is significant to assess the risk of NPPs, and to identify the design and operational vulnerabilities. Even though the combined accident is very rare event, the consequence of combined

    There is little research regarding characteristics of effective continuing medical education (CME) presentations in hospital medicine (HM). Therefore, we sought to identify associations between validated CME teaching effectiveness scores and characteristics of CME presentations in the field of HM. This was a cross-sectional study of participants and didactic presentations from a national HM CME course in 2014. Participants provided CME teaching effectiveness (CMETE) ratings using an instrument with known validity evidence. Overall CMETE scores (5-point scale: 1 = strongly disagree; 5 = strongly agree) were averaged for each presentation, and associations between scores and presentation characteristics were determined using the Kruskal-Wallis test. The threshold for statistical significance was set at P teaching effectiveness scores and characteristics of effective CME presentations in HM. Our findings, which support previous research in other fields, indicate that CME presentations may be improved by increasing interactivity through the use of audience response systems and allowing longer presentations. © 2015 Society of Hospital Medicine.

    The correct management of genitals and breast cancers and the improving of the preventional and therapeutical successes ratio involve the knowledge of the histopathological features of these nosological entities which have different origins, different risk factors, different simptomatology and also different prognosis. The descriptive evaluation of the histopathological features of the genitals and breast cancers to women from North-Eastern region of Romania. We have been included in the study 96 women (age range 23-77 years, mean 54,49) diagnosed with breast cancer, ovarian cancer, endometrial cancer and cervical cancer at the hospital admission, residency in the Obstetrics and Gynecology Clinics within 23 months. The following main parameters were assessed: histological types, stage at diagnosis, Pap test. After data collection, these have been codified and included in a MS Excel Database, in order to be processed with SPSS 16 and EpiInfo 3.5.1. (2008) Softwares. The following cases' repartition on diagnostic types was observed: breast cancer (44 cases), cervical cancer (24 cases), endometrial cancer (16 cases) and ovarian cancer (12 cases). In our study, the most affected range of age was 40-69 years for breast cancer, 30-59 years for cervical cancer, over 6 years for endometrial cancer and 50-59 years for ovarian cancer. For the cervical neoplasia, 40% of analyzed cases were in incipient stages (in situ to IB stage lessions). More than 50% of breast cancer cases have been diagnosed in advances stages (IIB to IIIC stages). For the endometrium carcinoma, 45% of cases have been identified in incipient stages (in situ to IC). The ovarian neoplasia cases have been detected, most frequently, in advanced stages (III and IV). 25% of women which participated in our study had showed cervical changes. From a histopathological point of view, for cervical neoplasia, squamous carcinoma was the most frequent type (87%), for breast neoplasia--invasive ductal carcinoma (80

    β-N-Acetylhexosaminidase was identified from Bacillus sp. CH11 and found to have relatively high transferring activity. In this study, its enzymatic properties and transglycosylation activity including its acceptor specificity were investigated. Its molecular weight was estimated to be 90 kDa by SDS-PAGE and its optimal pH was approximately 7 with good stability from pH 6 to 8. Its optimal temperature was 40 °C, and its activity was stable at temperatures of up to 40 °C. To analyze its acceptor specificity for transglycosylation, N, N'-diacetylchitobiose was used as a donor substrate and alcohols, sugar alcohols, sugars and polyphenols were used as acceptors. Dialcohols, which have 2 hydroxyl groups on the outside of the carbon chains, were good acceptors. The molecular size of the acceptor did not influence the transglycosylation up to at least 1,5-pentanediol (carbon number: C5). Glycerin (C3), erythritol (C4), and xylitol (C5), all small molecular weight sugar alcohols, had high acceptor specificity. Transglycosylation to mono- and disaccharides and polyphenols was not observed except for L-fucose. For the β-N-acetylhexosaminidase-catalyzed transglycosylation of chitin oligosaccharides and xylitol, the transfer product was identified as 1-O-β-D-N-acetylglucosaminyl xylitol. The optimal ratio of xylitol was 24% to 2% N, N'-diacetylchitobiose and 226 mg per 1 g N, N'-diacetylchitobiose was produced. CH11 β-N-acetylhexosaminidase efficiently produced 1-O-β-D-N-acetylglucosaminyl xylitol via transglycosylation. The new transfer products including 1-O-β-D-N-acetylglucosaminyl xylitol are attractive compounds for their potential physiological functions. 1-O-β-D-N-Acetylglucosaminyl xylitol was produced effectively from chitin-oligosaccharides and xylitol by β-N-acetylhexosaminidase from Bacillus sp. CH11. This enzyme may be useful for the development of food materials for health-related applications such as oligosaccharides with intestinal functions and

    Full Text Available BACKGROUND: To describe the characteristics, clinical presentations, management and complications of snakebites in the border region between Al-Ain, United Arab Emirates (UAE and Buraimi, Sultanate of Oman. METHODOLOGY/PRINCIPAL FINDINGS: We carried out a retrospective review of medical records to study snakebite cases over four-year duration at three tertiary hospitals. Overall, 64 snakebite cases were studied with median hospitalization of 2 (interquartile range [IQR] 1-4 days. The majority of cases were male (87.5%, and most (61% of the incidents occurred during summer months. The bite sites were predominantly (95% to the feet and hands. Main clinical features included pain, local swelling, and coagulopathy, blistering and skin peeling. Overall, there were no deaths, but few major complications occurred; extensive skin peeling (n = 5, 8%, multi-organ failure (n = 1, 1.5%, and compartment syndrome (n = 1, 1.5%. Polyvalent anti snake venom (ASV, analgesia, tetanus toxoid, intravenous fluids, and antibiotics such as ampicillin, cloxacillin, and cephalosporins were commonly instituted as part of treatment protocols in the three hospitals. CONCLUSION: The overwhelming majority of bites occurred during summer months, and envenomations were more common in, relatively, young male farmers, but with no serious clinical complications. Prevention and treatment strategies should include increasing public awareness, developing management guidelines, and manufacturing specific ASV for a wide spectrum of the local venomous snakes.

    Karolinska Rennes (KaRen) is a prospective observational study to characterize heart failure patients with preserved ejection fraction (HFpEF) and to identify prognostic factors for long-term mortality and morbidity. To report characteristics and echocardiography at entry and after 4-8 weeks of follow-up. Patients were included following an acute heart failure presentation with B-type natriuretic peptide (BNP)>100 ng/L or N-terminal pro-BNP (NT-proBNP)>300 ng/L and left ventricular ejection fraction (LVEF)>45%. The mean ± SD age of 539 included patients was 77 ± 9 years and 56% were women. Patient history included hypertension (78%), atrial tachyarrhythmia (44%), prior heart failure (40%) and anemia (37%), but left bundle branch block was rare (3.8%). Median NT-proBNP was 2448 ng/L (n=438), and median BNP 429 ng/L (n=101). Overall, 101 patients did not return for the follow-up visit, including 13 patients who died (2.4%). Apart from older age (80 ± 9 vs. 76 ± 9 years; P=0.006), there were no significant differences in baseline characteristics between patients who did and did not return for follow-up. Mean LVEF was lower at entry than follow-up (56% vs. 62%; P<0.001). At follow-up, mean E/e' was 12.9 ± 6.1, left atrial volume index 49.4±17.8mL/m(2). Mean global left ventricular longitudinal strain was -14.6 ± 3.9%; LV mass index was 126.6 ± 36.2g/m(2). Patients in KaRen were old with slight female dominance and hypertension as the most prevalent etiological factor. LVEF was preserved, but with increased LV mass and depressed LV diastolic and longitudinal systolic functions. Few patients had signs of electrical dyssynchrony (ClinicalTrials.gov.- NCT00774709).

    Full Text Available Somatically acquired genomic alterations with MYCN amplification (MNA are key features of neuroblastoma (NB, the most common extra-cranial malignant tumour of childhood. Little is known about the frequency, clinical characteristics and outcome of NBs harbouring genomic amplification(s distinct from MYCN.Genomic profiles of 1100 NBs from French centres studied by array-CGH were re-examined specifically to identify regional amplifications. Patients were included if amplifications distinct from the MYCN locus were seen. A subset of NBs treated at Institut Curie and harbouring MNA as determined by array-CGH without other amplification was also studied. Clinical and histology data were retrospectively collected.In total, 56 patients were included and categorised into 3 groups. Group 1 (n = 8 presented regional amplification(s without MNA. Locus 12q13-14 was a recurrent amplified region (4/8 cases. This group was heterogeneous in terms of INSS stages, primary localisations and histology, with atypical clinical features. Group 2 (n = 26 had MNA as well as other regional amplifications. These patients shared clinical features of those of a group of NBs MYCN amplified (Group 3, n = 22. Overall survival for group 1 was better than that of groups 2 and 3 (5 year OS: 87.5%±11% vs 34.9%±7%, log-rank p<0.05.NBs harbouring regional amplification(s without MNA are rare and seem to show atypical features in clinical presentation and genomic profile. Further high resolution genetic explorations are justified in this heterogeneous group, especially when considering these alterations as predictive markers for targeted therapy.

Little is known about the frequency, clinical characteristics and outcome of NBs harbouring genomic amplification(s) distinct from MYCN. Methods Genomic profiles of 1100 NBs from French centres studied by array-CGH were re-examined specifically to identify regional amplifications. Patients were included if amplifications distinct from the MYCN locus were seen. A subset of NBs treated at Institut Curie and harbouring MNA as determined by array-CGH without other amplification was also studied. Clinical and histology data were retrospectively collected. Results In total, 56 patients were included and categorised into 3 groups. Group 1 (n = 8) presented regional amplification(s) without MNA. Locus 12q13-14 was a recurrent amplified region (4/8 cases). This group was heterogeneous in terms of INSS stages, primary localisations and histology, with atypical clinical features. Group 2 (n = 26) had MNA as well as other regional amplifications. These patients shared clinical features of those of a group of NBs MYCN amplified (Group 3, n = 22). Overall survival for group 1 was better than that of groups 2 and 3 (5 year OS: 87.5%±11% vs 34.9%±7%, log-rank p<0.05). Conclusion NBs harbouring regional amplification(s) without MNA are rare and seem to show atypical features in clinical presentation and genomic profile. Further high resolution genetic explorations are justified in this heterogeneous group, especially when considering these alterations as predictive markers for targeted therapy. PMID:25013904

    A significant proportion of patients with acute stroke symptoms have an alternative 'mimic' diagnosis. A narrative review was carried out to explore the frequency, characteristics and aetiology of stroke mimics. Prehospital and thrombolysis-treated patients were described separately. Overall, 9972 studies were identified from the initial search and 79 studies were included with a median stroke mimic rate of 19% (range: 1-64%). The prehospital median was 27% (range: 4-43%) and the thrombolysis median 10% (range: 1-25%). Seizures, migraines and psychiatric disorders are the most frequently reported causes of stroke mimics. Several characteristics are consistently associated with stroke mimics; however, they do not fully exclude the possibility of stroke. Nineteen per cent of suspected stroke patients had a mimic condition. Stroke mimics were more common with younger age and female sex. The range of mimic diagnoses, a lack of clear differentiating characteristics and the short treatment window for ischaemic stroke create challenges for early identification.

    Pulmonary sequestration (PS) is a rare congenital abnormality of lung tissue. Only few series of adult cases are reported. The aim was to describe clinical characteristics in adult cases of PS and to compare outcomes in different clinical situations. Using MSD engine we searched for cases of PS that have been diagnosed between Jan 1st, 2005 and Dec 31st, 2015. Clinical data was retrospectively gathered. Statistica v.12 (StatSoft, Inc.) was used for statistical analyses. We found 25 cases (18 females, 7 males), which underwent surgery and were histologically proven. There were 22 cases of intralobar PS. 7 cases were asymptomatic, 12 had infectious history (including 3 cases of lung abscess and pleural empyema), 4 presented with hemoptysis, 2 with chest pain. The average age to undergo surgery was 38.24, in the asymptomatic group 34, in symptomatic 39.89. In the latter the symptoms preceded the surgery for 2.45-year. Great majority of sequestrations was located in lower lobes (96%), 52% on the left. Symptomatic cases were at higher than expected risk of surgical complications, comparing to asymptomatic (chi 2 , P=0.04). In most cases there were surgical and histological signs of infection, only in 9 cases etiological factor was determined: in 5 cases it was A. fumigatus . A 0.53-day longer post-surgical hospital stay was observed in the symptomatic group, no statistical significance was found (U-test, P=0.45). Surgical treatment of symptomatic cases of PS is characterized by slightly longer post-surgical hospital stay and higher risk of surgical complications. Fungal infections are the most likely to occur in PS.

  12. A quasi-static algorithm that includes effects of characteristic time scales for simulating failures in brittle materials

    When the brittle heterogeneous material is simulated via lattice models, the quasi-static failure depends on the relative magnitudes of Telem, the characteristic releasing time of the internal forces of the broken elements and Tlattice, the characteristic relaxation time of the lattice, both of which are infinitesimal compared with Tload, the characteristic loading period. The load-unload (L-U) method is used for one extreme, Telem << Tlattice, whereas the force-release (F-R) method is used for the other, Telem T lattice. For cases between the above two extremes, we develop a new algorithm by combining the L-U and the F-R trial displacement fields to construct the new trial field. As a result, our algorithm includes both L-U and F-R failure characteristics, which allows us to observe the influence of the ratio of Telem to Tlattice by adjusting their contributions in the trial displacement field. Therefore, the material dependence of the snap-back instabilities is implemented by introducing one snap-back parameter γ. Although in principle catastrophic failures can hardly be predicted accurately without knowing all microstructural information, effects of γ can be captured by numerical simulations conducted on samples with exactly the same microstructure but different γs. Such a same-specimen-based study shows how the lattice behaves along with the changing ratio of the L-U and F-R components. © 2013 The Author(s).

    Trauma due to accidents or fall from height is a major cause of disability and mortality. The present study was designed aiming to evaluate the baseline characteristics of fall from height victims presenting to emergency department (ED). This prospective cross-sectional study evaluates the baseline characteristics of fall from height cases presenting to EDs of three educational Hospitals, Tehran, Iran, during one year. Data were analyzed using SPSS 21 and presented using descriptive statistics. 460 patients with the mean age of 27.89 ± 20.95 years were evaluated (76.5% male). 191 (41.5%) falls occurred when working, 27 (5.9%) during play, and 242 (52.6%) in other times. Among construction workers, 166 (81.4%) had not used any safety equipment. Fracture and dislocation with 180 (39.1%) cases and soft tissue injury with 166 (36.1%) were the most common injuries inflicted. Mean height of falling was 3.41 ± 0.34 (range: 0.5 - 20) meters. Finally, 8 (1.7%) of the patients died (50% intentional) and 63% were discharged from ED. A significant correlation was detected between mortality and the falls being intentional (p construction workers, with less than high school diploma education level. Intentional fall and greater height of falling significantly correlated with mortality.

    Full Text Available with the development of society, interpersonal relation has become more and more complicated. “Face” has been defined as “public self-image” and occupies a very important position in interpersonal communication. Therefore, this thesis mainly studies the characteristics of Chinese language in the presentation of “face”. At first, it referred to current situation of face studies overseas. It can be seen that the “defense-protect” face work theory proposed by Goffman is the important foundation for face problem studies under different angles in academic world. Then, it discussed identity theory based on social psychology in combination of our traditional culture. At last, it selected 85 groups of effective linguistic data according to characteristics of Chinese language; and studied face work. Moreover, it conducted questionnaire survey in combination of face work theory. Thus, it obtained the core factors of face and other important conclusions.

    The common Aconitum herbs in clinical application mainly include Aconiti Radix(Chuanwu), Aconiti Kusnezoffii Radix(Caowu) and Aconiti Lateralis Radix Praeparaia(Fuzi), all of which have toxicity. Therefore, the safety of using Chinese patent drugs including Aconitum herbs has become an hot topic in clinical controversy. Based on the data-mining methods, this study explored the characteristics and causes of adverse drug reactions/events (ADR/ADE) of the Chinese patent drugs including Aconitum, in order to provide pharmacovigilance and rational drug use suggestions for clinical application. The detailed ADR/ADE reports about the Chinese patent drugs including Aconitum herbs were retrieved in the domestic literature databases since 1984 to now. The information extraction and data-mining were conducted based on the platforms of Microsoft office Excel 2016, Clementine 12.0 and Cytoscape 3.3.0. Finally, 78 detailed ADR/ADE reports involving a total of 30 varieties were included. 92.31% ADR/ADE were surely or likely led by the Chinese patent drugs including Aconitum, mostly involving multiple system/organ damages with good prognosis, and even 1 case of death. The incidence of included ADRs/ADEs was associated with various factors such as the patient idiosyncratic, drug toxicity, as well as clinical medication. The patient age was most closely related to ADR/ADEs, and those aged from 60 to 69 were more easily suffered from the ADRs/ADEs of Chinese patent drugs including Aconitum. The probability of ADR/ADEs for the drugs including Chuanwu or Caowu was greater than that of Fuzi, and the using beyond the instructions dose was the most important potential safety hazard in the clinical medication process. For the regular and characteristics of ADR/ADEs led by Chinese patent drugs including Aconitum, special attention shall be paid to the elder patients or with the patients with allergies; strictly control the dosage and course of treatment, strengthen the safety medication

    To describe the characteristics of patients with rheumatoid arthritis (RA) attending for physiotherapy management in Ireland. Managers of physiotherapy departments in the 53 hospitals in Ireland were invited to participate in a multi-centre observational study over a 6-month period. Data on patients with RA the day of presentation for physiotherapy management were recorded. These data related to patient demographic details, disease management, aids and appliances, splint and orthoses usage and occupational issues. The Health Assessment Questionnaire was also recorded for each patient. A total of 273 patients from eight physiotherapy departments participated in the survey (n = 199; 73% female). Mean age of the participants was 59.3 (SD 12.5) years with mean disease duration of 13.8 (SD 10.6) years. The majority of the patients were inpatients (n = 170, 62%). Sixty-eight per cent of patients had attended for previous physiotherapy treatment and 98% were under current rheumatologist care. Biologic therapies were prescribed to 11% of patients. Use of splint and foot orthoses was high with 133 patients (49%) wearing splints and 75 (31%) wearing foot orthoses. The majority of patients had moderate (n = 119, 44%) or severe (n = 94, 35%) disability as per Health Assessment Questionnaire (HAQ) score. Mean HAQ score was 1.5, with HAQ scores showing increasing disability with increasing age, disease duration and erythrocyte sedimentation rate (ESR) levels. Patients with RA attending for physiotherapy management present with varied profiles. This study provides valuable information on the characteristics of patients with RA attending for physiotherapy management which will contribute to physiotherapy service planning and delivery and will optimize patient care.

    Objective: The difference in arterial supply, venous drainage, functional localization in supratentorial and infratentorial compartments may contribute to the conflicting results about risk factors for hemorrhage in published case series of brain arteriovenous malformation (bAVM). Further investigation focused on an individual brain compartment is thus necessary. This retrospective study aims to identify angioarchitectural characteristics associated with the initial hemorrhagic event of supratentorial bAVMs. Materials and methods: The clinical and angiographic features of 152 consecutive patients with supratentorial bAVMs who presented to our hospital from 2005 to 2008 were retrospectively reviewed. All these patients had new diagnosis of bAVM. Univariate (χ{sup 2} test) and multivariate analyses were conducted to assess the angiographic features in patients with and without initial hemorrhagic presentations. A probability value of less than 0.05 was considered statistically significant in each analysis. Results: In 152 patients with supratentorial AVMs, 70.6% of deep and 52.5% of superficial sbAVMs presented with hemorrhage. The deep location was correlated with initial hemorrhagic presentation in univariate analysis (χ{sup 2} = 3.499, p = 0.046) but not in the multivariate model (p = 0.144). There were 44 sbAVMs with perforating feeders, 39 (88.6%) of which bled at a significantly higher rate than those with terminal feeders (χ{sup 2} = 25.904, p = 0.000). 87.5% (21/24) of exclusive deep venous drainage presented with hemorrhage, a significantly higher rate than those of the other type of venous drainage (χ{sup 2} = 11.099, p = 0.004). All 10 patients with both perforating feeders and exclusive deep draining vein presented with initial hemorrhage. Hemorrhagic presentation was correlated with perforating feeders (p = 0.000) and exclusive deep draining vein (p = 0.007) in multivariate analysis as well. Conclusions: Supratentorial bAVMs with perforating feeders

    This study was designed to reveal the correlationship between the internal derangement state of TMJ and clinical characteristics including pain and mandibular dysfuntion. One hundred and twenty five subjects with TMJ signs and symptoms were chosen for two years. The level of pain and mandibular dysfuntion were evaluated by Visual Analog Scale (VAS) and Craniomandibular Index (CMI). The diagnostic categories of TMJ internal derangement were determined by arthrography and they included normal disc position, anterior disc displacement with reduction (ADDR), rotational disc displacement with reduction (RDDR), andterior disc displacement without reduction (ADDNR), and rotational disc displacement without reduction (RDDNR). Also disc perforation was used as a criteria to divide the diagnostic subgroups. The obtained results were as follows ; 1. The patient distribution of each group was 5 in normal disc position (4%), 40 in ADDR (32%), 30 in RDDR (24%), 34 in ADDNR (27%), and 16 in RDDNR (13%). 2. Perforation was observed in 8% of ADDR, 10% of RDDR, 32% of ADDNR, and 19% of RDDNR. 3. CMI of perforation group was higher than that of reduction or normal group(p 0.05).

    To assess psychosocial characteristics, symptoms and reasons for seeking integrative medicine (IM) care in cancer patients presenting to IM clinical practices. A survey of 3940 patients was conducted at 8 IM sites. Patient reported outcome measures were collected and clinicians provided health status data. This analysis compares 353 participants self-identified as cancer patients with the larger noncancer cohort. Mean age of the cancer cohort was 55.0 years. Participants were predominantly white (85.9%), female (76.4%), and well educated (80.5% completed college). For 15.2% of cancer patients, depression scores were consistent with depressive symptoms, and average scores for perceived stress were higher than normal, but neither were significantly different from noncancer patients. The most prevalent comorbid symptoms were chronic pain (39.8%), fatigue (33.5%), and insomnia (23.3%). In the cancer cohort, perceived stress was significantly associated with depression, fatigue, insomnia, pain, and QOL. Cancer patients who chose an IM clinical practice "seeking healthcare settings that address spirituality as an aspect of care" had significantly higher levels of perceived stress, depression, and pain than those not selecting this reason. Demographic characteristics, depression scores, perceived stress scores, and reasons for seeking integrative cancer care were not significantly different between cancer patients and noncancer patients. Perceived stress may be an important indicator of QOL. The association of perceived stress, depression and pain with seeking spirituality suggests that providing IM interventions, such as effective stress management techniques and pastoral or spiritual counseling, may be helpful to patients living with cancer. © The Author(s) 2014.

    To identify the characteristics of successful research projects at an internal medicine residency program with an established research curriculum. The authors collected data about all research projects initiated by or involving medicine residents from 2006 to 2013 at Baystate Medical Center, using departmental files and institutional review board applications. Resident and mentor characteristics were determined using personnel files and Medline searches. Using multivariable models, the authors identified predictors of successful completion of projects using adjusted prevalence ratios (PRs). The primary outcome was manuscript publication by resident and secondary outcome was either publication or regional/national presentation. Finally, residents were surveyed to identify barriers and/or factors contributing to project completion. Ninety-four research projects were identified: 52 (55.3%) projects achieved the primary outcome and 72 (76.5%) met the secondary outcome, with overlap between categories. Most study designs were cross-sectional (41, 43.6%) or retrospective cohort (30, 31.9%). After adjustment, utilization of the epidemiology/biostatistical core (PR = 2.09; 95% CI: 1.36, 3.21), established publication record of resident (PR = 1.54, 95% CI: 1.14, 2.07), and resident with U.S. medical education (PR = 1.39, 95% CI: 1.02, 1.90) were associated with successful completion of projects. Mentor publication record (PR = 3.13) did not retain significance due to small sample size. Most respondents (65%) cited "lack of time" as a major project barrier. Programs seeking to increase resident publications should consider an institutional epidemiology/biostatistical core available to all residency research projects, and residents should choose experienced mentors with a track record of publications.

    Catastrophic life events are associated with the occurrence of cardiovascular incidents and worsening of the clinical course followirg-such events. To evaluate the characteristics and long-term prognosis of Holocaust survivors presenting with acute myocardial infarction (AMI) compared to non-Holocaust survivors. Israeli Jews who were born before 1941 and had been admitted to a tertiary medical center due to AMI during the period 2002-2012 were studied. Holocaust survivors were compared with non-Holocaust survivor controls using individual age matching. Overall 305 age-matched pairs were followed for up to 10 years after AMI. We found a higher prevalence of depression (5.9% vs. 3.3%, P = 0.045) yet a similar rate of cardiovascular risk factors, non-cardiovascular co-morbidity, severity of coronary artery disease, and in-hospital complications in survivors compared to controls. Throughout the follow-up period, similar mortality rates (62.95% vs. 63.9%, P = 0.801) and reduced cumulative mortality (0.9 vs. 0.96, HR = 0.780, 95% CI 0.636-0.956, P = 0.016) were found among survivors compared to age-matched controls, respectively. However, in a multivariate analysis survival was not found to be an independent predictor of mortality, although some tendency towards reduced mortality was seen (AdjHR = 0.84, 95% CI 0.68-1.03, P = 0.094). Depression disorder was associated with a 77.9% increase in the risk for mortality. Holocaust survivors presenting with AMI were older and had a higher prevalence of depression than controls. No. excessive, and possibly even mildly improved, risk of mortality.was observed in survivors compared with controls presenting with AMI. Possibly, specific traits that are associated with surviving catastrophic events counter the excess risk of such events following AMI.

    Objective The purpose of this study was to compare demographics and chief complaints of the new patient population at our institution's fee-for-service clinics to the patient population of practicing chiropractors in the United States. We also compared the prevalence of obesity and hypertension to reference standards for the adult population. Methods Patient data were obtained from the electronic health records. All records identified as new patients during October 2013 were included. Variables of interest were clinic site, patient demographics, blood pressure, body mass index (BMI), chief complaint, and ICD-9 codes. Descriptive statistics were computed and compared to reference standards from previous reports. Results During October 2013, there were 224 new patients that entered the clinics. The average patient was a 31- to 50-year-old white male. Our clinic patients differed from those seen by US chiropractors in the distribution of all demographic variables. For adult patients, 31.4% were overweight, 29% were obese, and 8% stage 1 or 2 hypertension. Conclusion New patients in the fee-for-service teaching clinics appear to be dissimilar to those of US practicing chiropractors in several important demographics, characteristics, and types of complaints. The new patients had lower levels of overweight, obesity, and hypertension compared to US reference standards. PMID:25162982

    Conspicuous facial pores are one type of serious aesthetic defects for many women. However, the mechanism(s) that underlie the conspicuousness of facial pores remains unclear. We previously characterized the epidermal architecture around facial pores that correlates with the appearance of those pores in various ethnic groups including Japanese. The goal of this study was to evaluate the possible relationships between facial pore size, the severity of impairment of epidermal architecture around facial pores and sebum output levels to investigate the possible role of IGF-1 in the pathogenesis of conspicuous facial pores. The subjects consisted of 38 healthy Japanese women (aged 22-41 years). IGF-1 was measured using immunoradiometric assay. Surface replicas were collected to compare pore sizes of cheek skin and horizontal cross-section images of cheek skin were obtained non-invasively from the same subjects using in vivo confocal laser scanning microscopy and the severity of impairment of epidermal architecture around facial pores was determined. The skin surface lipids of each subject were collected from their cheeks and lipid classes were determined using gas chromatography/flame ionization detection. The serum level of IGF-1 correlated significantly with total pore area (R = 0.36, P facial pores (R = 0.43, P pore area (R = 0.32, P facial skin characteristics including facial pore size and with the severity of impairment of epidermal architecture around facial pores. © 2010 The Authors.

    GraphROC for Windows is a program for clinical test evaluation. It was designed for the handling of large datasets obtained from clinical laboratory databases. In the user interface, graphical and numerical presentations are combined. For simplicity, numerical data is not shown unless requested. Relevant numbers can be "picked up" from the graph by simple mouse operations. Reference distributions can be displayed by using automatically optimized bin widths. Any percentile of the distribution with corresponding confidence limits can be chosen for display. In sensitivity-specificity analysis, both illness- and health-related distributions are shown in the same graph. The following data for any cutoff limit can be shown in a separate click window: clinical sensitivity and specificity with corresponding confidence limits, positive and negative likelihood ratios, positive and negative predictive values and efficiency. Predictive values and clinical efficiency of the cutoff limit can be updated for any prior probability of disease. Receiver Operating Characteristics (ROC) curves can be generated and combined into the same graph for comparison of several different tests. The area under the curve with corresponding confidence interval is calculated for each ROC curve. Numerical results of analyses and graphs can be printed or exported to other Microsoft Windows programs. GraphROC for Windows also employs a new method, developed by us, for the indirect estimation of health-related limits and change limits from mixed distributions of clinical laboratory data.

    Angiodysplasia is important in the differential diagnosis of upper gastrointestinal bleeding (UGIB), but the clinical features and outcomes associated with UGIB from angiodysplasia have not been characterized. We aimed to analyze the clinical characteristics and outcomes of angiodysplasia presented as UGIB. Between January 2004 and December 2013, a consecutive series of patients admitted with UGIB were retrospectively analyzed. Thirty-five patients with bleeding from angiodysplasia were enrolled. We compared them with an asymptomatic control group (incidental finding of angiodysplasia in health screening, n = 58) and bleeding control group (simultaneous finding of angiodysplasia and peptic ulcer bleeding, n = 28). When patients with UGIB from angiodysplasia were compared with the asymptomatic control group, more frequent rates of nonantral location and large sized lesion (≥ 1 cm) were evident in multivariate analysis. When these patients were compared with the bleeding control group, they were older (mean age: 67.94 ± 9.16 years vs.55.07 ± 13.29 years, p = 0.03) and received less transfusions (p = 0.03). They also had more frequent rate of recurrence (40.0% vs. 20.7%, p = 0.02). Non-antral location and large lesions (≥ 1 cm) could be risk factors of UGIB of angiodysplasia. UGIB due to angiodysplasia was more common in older patients. Transfusion requirement would be less and a tendency of clinical recurrence might be apparent.

    The Emergency Department (ED) has been shown to be a valuable location to screen for family violence. To investigate the characteristics of family violence victims presenting to EDs in a Chinese population in Hong Kong. This study examined a retrospective cohort of patients presenting to the Accident and Emergency Departments of three regional hospitals in the Kwai Tsing district of Hong Kong for evaluation and management of physical injuries related to family violence during the period of January 1, 1997 to December 31, 2008. A total of 15,797 patients were assessed. The sample comprised cases of intimate partner violence (IPV; n=10,839), child abuse and neglect (CAN; n=3491), and elder abuse (EA; n=1467). Gender differences were found in patterns of ED utilization among the patients. The rates of readmission were 12.9% for IPV, 12.8% for CAN, and 8.9% for EA. Logistic regression showed that being male, being discharged against medical advice, and arriving at the hospital via ambulance were the common factors associated with readmission to the EDs for patients victimized by IPV and CAN. This study investigates the victim profile of a large cohort of a Chinese population, providing a unique data set not previously released in this cultural or medical system. The findings give insights to early identification of victims of family violence in the EDs and suggest that screening techniques focused on multiple forms of family violence would improve identification of violence cases. Multidisciplinary collaboration between health, legal, and social service professionals is also warranted to meet the various needs of victims and to reduce hospital readmissions.

    Full Text Available In vitro fermentation systems such as the rumen simulation technique (RUSITEC are frequently used to assess dietary manipulations in livestock, thereby limiting the use of live animals. Despite being in use for nearly 40 years, improvements are continually sought in these systems to better reflect and mimic natural processes in ruminants. The aim of this study was to evaluate the effect of forage preparation, i.e., frozen minced (FM and freeze-dried and ground (FDG, on the ruminal microbiota and on fermentation characteristics when included as a substrate in a RUSITEC system. A completely randomized design experiment was performed over a 15-day period, with 7 days of adaptation and an 8-day experimental period. Fermentation parameters (total gas, CH4, and volatile fatty acid production were analyzed on a daily basis over the experimental period and the archaeal and bacterial microbiota (liquid-associated microbes [LAM] and solid-associated microbes [SAM] was assessed at 0, 5, 10, and 15 days using high-throughput sequencing of the 16S rRNA gene. Results from this study suggested a tendency (P = 0.09 of FM treatment to increase daily CH4 (mg/d production by 16.7% when compared with FDG treatment. Of the major volatile fatty acids (acetate, propionate, and butyrate, only butyrate production was greater (P = 0.01 with FM treatment compared with FDG substrate. The archaeal and bacterial diversity and richness did not differ between the forage preparations, although feed particle size of the forage had a significant effect on microbial community structure in the SAM and LAM samples. The Bacteroidetes phylum was more relatively abundant in the FM substrate treatment, while Proteobacteria was enriched in the FDG treatment. At the genus-level, Butyrivibrio, Prevotella, and Roseburia were enriched in the FM substrate treatment and Campylobacter and Lactobacillus in the FDG substrate treatment. Evidence from this study suggests that forage preparation

    Limited data are available regarding specific differences among countries in demographic and clinical characteristics and treatment of patients with stable coronary artery disease. CLARIFY is an international, prospective and longitudinal registry including more than 33 000 patients with stable coronary artery disease enrolled in 45 countries worldwide. Data were used to compare the characteristics of patients enrolled in Italy with those enrolled in Europe and in the rest of the world. Baseline data were available for 33 283 patients, 2112 of whom from Italy and 12 614 from the remaining western European countries. Italian patients were found to be older, more frequently smoker, hypertensive and with sedentary habits. In addition, they presented more frequently a history of myocardial infarction, carotid arterial disease and chronic obstructive pulmonary disease. In addition, when compared with patients of both European and international cohorts, more Italian patients had undergone coronary angiography and angioplasty. As far as treatment was concerned, a greater number of Italian patients were taking ivabradine, angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers, nitrates, thienopyridines, while those taking beta-blockers, calcium antagonists and other antianginal medications were fewer. Among ambulatory patients with stable coronary artery disease, there are important geographic differences in terms of risk factors, clinical characteristics, surgical and pharmacological treatment.

    Leiomyoma, a benign neoplasia arising from smooth muscle is an uncommon neoplasia of the oral cavity. The most common histological subtype in the oral cavity is the vascular one. To supplement information on vascular leiomyoma of the oral cavity (VLOC), we present cases of VLOC describing their clinical, histological, and immunohistochemical characteristics. Case reports. Five cases of VLOC (3 females; 2 males) from the Clinical and Experimental Pathology Laboratory, Dental School, National Autonomous University of México, are included. The most frequent clinical characteristic of VLOC was a single, asymptomatic, slow growing nodule. The age average of the cases was 40.6, however 3 out of our 5 cases were < or = 40 years old at the moment of their diagnosis. The lesions were composed of fusiform cells arranged in bundles or fascicles. The neoplastic cells were characterized by eosinophilic cytoplasm and tapered nuclei. The presence of vascular spaces was prominent in all cases. The immunocharacteristics of VLOC neoplastic cells were: alpha smooth muscle (+); vimentin (+), desmin (+), CD34 (-) and S-100 protein (-). The endothelial cells of vascular spaces were CD34 (+). Differential diagnosis of VLOC with fusocellular neoplasm is discussed.

    Objective: To determine the frequency of clinopathological characteristics of systemic lupus erythematosus (SLE) patients presenting to Military Hospital (MH) Rawalpindi. Study Design: Descriptive cross sectional study. Place and Duration of Study: The study was carried out at MH Rawalpindi, from Jan 2011 to Dec 2013. Material and Methods: All patients presenting to Rheumatology department, MH Rawalpindi with a diagnosis of SLE were included in this study. Presenting features, clinical profile and laboratory parameters of patients were recorded. Results: A total of 76 patients were included in this study, 70 (92.1%) were females and 6 (7.9%) male patients with female- male ratio of 11.6:1. Mean age at presentation was 33 ± 8.31 years. Seventy two patients (94.7%) were anti nuclear antibody (ANA) positive, 63 (83%) were positive for anti-double stranded deoxyribonucleic acid (anti-dsDNA) antibody and 6 (7.9%) were anti Smith positive. Seventy (92.1%) patients had musculoskeletal symptoms, 65 patients (85.5%) had fever, 36 (47.4%) patients had cutaneous symptoms, and 20 patients (26.3%) had oral ulcers. About 13 patients (17.1%) had alopecia and 15 patients (19.7%) had serositis. Forty two patients (55.3%) had nephritis, 20 patients (26.3%) had lupus cerebritis, 57 patients (75%) had hematological involvement, 9 patients (11.83%) had pulmonary involvement, 8 patients (10.5%) had rheumatoid arthritis (RA) factor positive and 7 patients (9.2%) had overlap syndrome. Conclusion: Renal and hematological involvement was more common in this study population while mucocutaneous features and neuropsychiatric features were comparable to many local studies with exception to that of Lahore based study that showed much higher percentage of these features. These results reflect the need to have a high index of suspicion for kidney and hematological involvement in SLE patients. (author)

    The median age at presentation for dogs with patent ductus arteriosus (PDA) is closure is associated with a decrease in heart size and increased survival time, which are not well described in older dogs. To describe the clinical characteristics of dogs with PDA ≥5 years of age at the time of presentation to a veterinary referral hospital. 35 client-owned dogs. Retrospective case series. PDA was diagnosed at a median age of 7.4 years (range, 5.1-12.3 years). Females represented 23/35 (65.7%) of the patients. Concurrent heart disease included degenerative mitral valve disease (DMVD; 13), arrhythmias (11), pulmonary hypertension (7), and other congenital defects (2). Cardiomegaly was documented in the majority of dogs consisting of left ventricular enlargement (91%) and left atrial enlargement (86%). Median vertebral heart size in 24 dogs was 12.9 (range, 10.7-18.2). The PDA shunt direction was left-to-right in 33 and bidirectional in 2 dogs. Closure was performed in 26 dogs, including 4 with pulmonary hypertension. In 10 dogs receiving furosemide pre-operatively for management of heart failure, furosemide was discontinued (8) or the dosage decreased (2) at the time of discharge. Adult dogs can present with a left-to-right shunting PDA that results in cardiomegaly and clinical signs that can improve or resolve with PDA closure. This improvement is also apparent in dogs with PDA complicated by DMVD. Pulmonary hypertension that does not result in complete right-to-left shunting should not be considered a contraindication to closure. Copyright © 2017 The Authors.

    Lipofibromatosis is a rare, benign fibrofatty tumor of childhood. Since the tumor was first characterized in 2000, only a few additional cases have been reported. The classic presentation of lipofibromatosis is a slow-growing mass arising in a distal extremity, with boys more commonly affected than girls. We report a 16-month-old girl who presented with a lipofibromatosis in her left scapular region that increased 30% in size during a 6-week period. Although previous case reports of lipofibromatosis have emphasized immunohistological findings, this paper focuses on imaging findings and discusses the utility of imaging in the differential diagnosis of pediatric soft-tissue tumors.

    We have fabricated several 10 nm thick and 65 nm wide YBa2Cu3O7-δ (YBCO) nanostrips. The nanostrips with the highest critical current densities are characterized by hysteretic current voltage characteristics (IVCs) with a direct bistable switch from the zero-voltage to the finite voltage state. The presence of hysteretic IVCs allowed the observation of dark pulses due to fluctuations phenomena. The key role of the bistable behavior is its ability to transform a small disturbance (e.g. an intrinsic fluctuation) into a measurable transient signal, i.e. a dark pulse. On the contrary, in devices characterized by lower critical current density values, the IVCs are non-hysteretic and dark pulses have not been observed. To investigate the physical origin of the dark pulses, we have measured the bias current dependence of the dark pulse rate: the observed exponential increase with the bias current is compatible with mechanisms based on thermal activation of magnetic vortices in the nanostrip. We believe that the successful amplification of small fluctuation events into measurable signals in nanostrips of ultrathin YBCO is a milestone for further investigation of YBCO nanostrips for superconducting nanostrip single photon detectors and other quantum detectors for operation at higher temperatures.

    In this study we present and empirically examine a new phenomenon related to social networking sites, such as Facebook, the "false Facebook-self." Arguably false self-presentation on Facebook is a growing phenomenon, and in extreme cases; i.e., when ones Facebook image substantially deviates from their true image, it may serve as a gateway behavior to more problematic behaviors which may lead to psychological problems and even pathologies. In this study we show that certain users are more vulnerable to such false self-presentation than others. The study involved 258 Facebook users. Applying ANOVA and SEM analyses we show that users with low self-esteem and low trait authenticity are more likely than others to present a Facebook-self which deviates from their true selves. These social-interaction-related traits are influenced by one's upbringing and the anxious and avoidant attachment styles he or she has developed. Several cases (7.5%) with large gaps between the true and false Facebook-self were detected, which implies that future research should consider the adverse consequences and treatments of high levels of false Facebook-self.

  3. Temporal characteristics of radiologists’ and novices’ lesion detection in viewing medical images presented rapidly and sequentially

    Full Text Available Although viewing multiple stacks of medical images presented on a display is a relatively new but useful medical task, little is known about this task. Particularly, it is unclear how radiologists search for lesions in this type of image reading. When viewing cluttered and dynamic displays, continuous motion itself does not capture attention. Thus, it is effective for the target detection that observers’ attention is captured by the onset signal of a suddenly appearing target among the continuously moving distractors (i.e., a passive viewing strategy. This can be applied to stack viewing tasks, because lesions often show up as transient signals in medical images which are sequentially presented simulating a dynamic and smoothly transforming image progression of organs. However, it is unclear whether observers can detect a target when the target appears at the beginning of a sequential presentation where the global apparent motion onset signal (i.e., signal of the initiation of the apparent motion by sequential presentation occurs. We investigated the ability of radiologists to detect lesions during such tasks by comparing the performances of radiologists and novices. Results show that overall performance of radiologists is better than novices. Furthermore, the temporal locations of lesions in CT image sequences, i.e., when a lesion appears in an image sequence, does not affect the performance of radiologists, whereas it does affect the performance of novices. Results indicate that novices have greater difficulty in detecting a lesion appearing early than late in the image sequence. We suggest that radiologists have other mechanisms to detect lesions in medical images with little attention which novices do not have. This ability is critically important when viewing rapid sequential presentations of multiple CT images, such as stack viewing tasks.

    To present a novel and simple graphical approach to improve the presentation of the treatment ranking in a network meta-analysis (NMA) including multiple outcomes. NMA simultaneously compares many relevant interventions for a clinical condition from a network of trials, and allows ranking of the effectiveness and/or safety of each intervention. There are numerous ways to present the NMA results, which can challenge their interpretation by research users. The rank-heat plot is a novel graph that can be used to quickly recognize which interventions are most likely the best or worst interventions with respect to their effectiveness and/or safety for a single or multiple outcome(s) and may increase interpretability. Using empirical NMAs, we show that the need for a concise and informative presentation of results is imperative, particularly as the number of competing treatments and outcomes in an NMA increases. The rank-heat plot is an efficient way to present the results of ranking statistics, particularly when a large amount of data is available, and it is targeted to users from various backgrounds.

  5. Distinct Adsorption Configurations and Self-Assembly Characteristics of Fibrinogen on Chemically Uniform and Alternating Surfaces including Block Copolymer Nanodomains

    Science.gov (United States)

    2015-01-01

    Understanding protein–surface interactions is crucial to solid-state biomedical applications whose functionality is directly correlated with the precise control of the adsorption configuration, surface packing, loading density, and bioactivity of protein molecules. Because of the small dimensions and highly amphiphilic nature of proteins, investigation of protein adsorption performed on nanoscale topology can shed light on subprotein-level interaction preferences. In this study, we examine the adsorption and assembly behavior of a highly elongated protein, fibrinogen, on both chemically uniform (as-is and buffered HF-treated SiO2/Si, and homopolymers of polystyrene and poly(methyl methacrylate)) and varying (polystyrene-block-poly(methyl methacrylate)) surfaces. By focusing on high-resolution imaging of individual protein molecules whose configurations are influenced by protein–surface rather than protein–protein interactions, fibrinogen conformations characteristic to each surface are identified and statistically analyzed for structural similarities/differences in key protein domains. By exploiting block copolymer nanodomains whose repeat distance is commensurate with the length of the individual protein, we determine that fibrinogen exhibits a more neutral tendency for interaction with both polystyrene and poly(methyl methacrylate) blocks relative to the case of common globular proteins. Factors affecting fibrinogen–polymer interactions are discussed in terms of hydrophobic and electrostatic interactions. In addition, assembly and packing attributes of fibrinogen are determined at different loading conditions. Primary orientations of fibrinogen and its rearrangements with respect to the underlying diblock nanodomains associated with different surface coverage are explained by pertinent protein interaction mechanisms. On the basis of two-dimensional stacking behavior, a protein assembly model is proposed for the formation of an extended fibrinogen network

    Data on the fish fauna of the Leschenault Estuary on the lower west coast of Australia were collected and used as a model to elucidate the characteristics of permanently open estuaries with a reverse salinity gradient, which undergo seasonal changes similar to many other estuaries with Mediterranean climate. Focus was placed on determining (1) the relationships of the number of species, density, life cycle category and species composition of fishes with region (within estuary), season and year and salinity, (2) whether species are partitioned along the lengths of such systems and (3) the extent and significance of any inter-decadal changes in species composition. The analyses and interpretation involved using multi-factorial permutational multivariate analysis of variance (PERMANOVA) and analysis of similarity (ANOSIM) designs, and three new or recently published visualization tools, i.e. modified non-metric multidimensional scaling (nMDS) plots, coherent species curves and segmented bubble plots. The base, lower, upper and apex regions of the Leschenault Estuary, along which the salinity increased in each season except in winter when most rainfall occurs, were sampled seasonally for the 2 years between winter 2008 and autumn 2010. Estuarine residents contributed twice as many individuals, but less than half the number of species as marine taxa. While the numbers of marine species and estuarine residents declined between the base or lower and apex regions, the individuals of marine species dominated the catches in the base region and estuarine residents in the other three regions. Ichthyofaunal composition in each region underwent conspicuous annual cyclical changes, due to time-staggered differences in recruitment among species, and changed sequentially along the estuary, both paralleling salinity trends. Different groups of species characterized the fauna in the different regions and seasons, thereby partitioning resources among species. The ichthyofauna of the

    Full Text Available Due to emphasis on early screening for lung cancer, the detection rate of multiple ground glass opacities (GGOs on computed tomography (CT image increases in recent years, and research on multifocal adenocarcinomas presented by GGOs has been thriving. It is more common in women and non-smokers and has excellent prognosis both in patients with natural history and after surgery. These clinical features suggest that it is likely to be a distinct disease entity. From the perspective of molecular genetics, lesions in the same individual are likely to have distinct clonal features. Therefore, genetic heterogeneity is the most prominent feature of multifocal pulmonary adenocarcinomas with GGOs. The genetic heterogeneity is expected to assist the diagnosis of multifocal pulmonary adenocarcinoma and intrapulmonary metastasis, and also suggests that genetic testing of the GGO lesions is of great therapeutic significance. Some GGO lesions may harvest the similar clonal feature, which provide new evidence for the theory of spread through air spaces (STAS.

    Due to emphasis on early screening for lung cancer, the detection rate of multiple ground glass opacities (GGOs) on computed tomography (CT) image increases in recent years, and research on multifocal adenocarcinomas presented by GGOs has been thriving. It is more common in women and non-smokers and has excellent prognosis both in patients with natural history and after surgery. These clinical features suggest that it is likely to be a distinct disease entity. From the perspective of molecular genetics, lesions in the same individual are likely to have distinct clonal features. Therefore, genetic heterogeneity is the most prominent feature of multifocal pulmonary adenocarcinomas with GGOs. The genetic heterogeneity is expected to assist the diagnosis of multifocal pulmonary adenocarcinoma and intrapulmonary metastasis, and also suggests that genetic testing of the GGO lesions is of great therapeutic significance. Some GGO lesions may harvest the similar clonal feature, which provide new evidence for the theory of spread through air spaces (STAS).

    Isolated hypogonadotropic hypogonadism (IHH) is a rare disorder with pubertal delay, normal (normoosmic-IHH, nIHH) or defective sense of smell (Kallmann syndrome, KS). Other reproductive and non-reproductive anomalies might be present although information on their frequency are scanty, particularly according to the age of presentation. Observational cohort study carried out between January 2008 and June 2016 within a national network of academic or general hospitals. We performed a detailed phenotyping of 503 IHH patients with: (1) manifestations of hypogonadism with low sex steroid hormone and low/normal gonadotropins; (2) absence of expansive hypothalamic/pituitary lesions or multiple pituitary hormone defects. Cohort was divided on IHH onset (PPO, pre-pubertal onset or AO, adult onset) and olfactory function: PPO-nIHH ( n  = 275), KS ( n  = 184), AO-nIHH ( n  = 36) and AO-doIHH (AO-IHH with defective olfaction, n  = 8). 90% of patients were classified as PPO and 10% as AO. Typical midline and olfactory defects, bimanual synkinesis and familiarity for pubertal delay were also found among the AO-IHH. Mean age at diagnosis was significantly earlier and more frequently associated with congenital hypogonadism stigmata in patients with Kallmann's syndrome (KS). Synkinesis, renal and male genital tract anomalies were enriched in KS. Overweight/obesity are significantly associated with AO-IHH rather than PPO-IHH. Patients with KS are more prone to develop a severe and complex phenotype than nIHH. The presence of typical extra-gonadal defects and familiarity for PPO-IHH among the AO-IHH patients indicates a common predisposition with variable clinical expression. Overall, these findings improve the understanding of IHH and may have a positive impact on the management of patients and their families. © 2018 European Society of Endocrinology.

    Full Text Available Abstract Background Undifferentiated acute febrile illness (AFI is a common presentation among adults in primary care settings in Singapore but large gaps exist in the understanding of the characteristics of these patients. We studied clinical and epidemiological characteristics of AFI patients and factors associated with delayed recovery from AFI. Methods We performed a secondary data analysis using data from the Early DENgue infection and outcome (EDEN study on 2046 adult patients presenting at 5 Singapore polyclinics between December 2007 and February 2013 with a history of fever (≥38 °C for less than 72 h. We used an accelerated failure time model to investigate factors associated with delayed recovery from AFI. Results The mean age of patients was 36.6 years, 65 % were male, 51 % were of Chinese ethnicity, and 75 % lived in public housing. Median illness duration was 5 days (interquartile range, 3–7. In multivariable analysis, the unemployed and white collar workers had longer illness duration compared with blue collar workers (time ratio (TR, 1.10; 95 % confidence interval (CI, 1.03–1.17 and TR, 1.08; 95 % CI, 1.02–1.15, respectively. Patients with more symptoms at initial consultation had slower recovery (TR, 1.03 per additional symptom; 95 % CI, 1.02–1.03. Other clinical factors were also associated with longer duration of illness, including use of analgesics (TR, 1.21; 95 % CI, 1.15–1.28; use of cough medicines (TR, 1.14; 95 % CI, 1.08–1.20; use of antibiotics (TR, 1.14; 95 % CI, 1.07–1.21; and hospitalization (TR, 1.59; 95 % CI, 1.39–1.82. Compared to patients with normal WBC count at first consultation, those with low WBC count had slower recovery (TR, 1.14; 95 % CI, 1.07–1.21, while the reverse was observed among patients with high WBC count (TR, 0.94; 95 % CI, 0.88–1.00.

    Full Text Available Abstract Background Neisseria meningitidis causes the life-threatening diseases meningococcal meningitis and meningococcal septicemia. Neisseria gonorrhoeae is closely related to the meningococcus, but is the cause of the very different infection, gonorrhea. A number of genes have been implicated in the virulence of these related yet distinct pathogens, but the genes that define and differentiate the species and their behaviours have not been established. Further, a related species, Neisseria lactamica is not associated with either type of infection in normally healthy people, and lives as a harmless commensal. We have determined which of the genes so far identified in the genome sequences of the pathogens are also present in this non-pathogenic related species. Results Thirteen unrelated strains of N. lactamica were investigated using comparative genome hybridization to the pan-Neisseria microarray-v2, which contains 2845 unique gene probes. The presence of 127 'virulence genes' was specifically addressed; of these 85 are present in N. lactamica. Of the remaining 42 'virulence genes' only 11 are present in all four of the sequenced pathogenic Neisseria. Conclusion Assessment of the complete dataset revealed that the vast majority of genes present in the pathogens are also present in N. lactamica. Of the 1,473 probes to genes shared by all four pathogenic genome sequences, 1,373 hybridize to N. lactamica. These shared genes cannot include genes that are necessary and sufficient for the virulence of the pathogens, since N. lactamica does not share this behaviour. This provides an essential context for the interpretation of gene complement studies of the pathogens.

    The Island of Hawai';i is home to the most active volcanoes in the Hawaiian Islands. The island's isolated nature, combined with the lack of permanent offshore seismometers, creates difficulties in recording small magnitude earthquakes with accuracy. This background offshore seismicity is crucial in understanding the structure of the lithosphere around the island chain, the stresses on the lithosphere generated by the weight of the islands, and how the volcanoes interact with each other offshore. This study uses the data collected from a 9-month deployment of a temporary ocean bottom seismometer (OBS) network fully surrounding Lo';ihi volcano. This allowed us to widen the aperture of earthquake detection around the Big Island, lower the magnitude detection threshold, and better constrain the hypocentral depths of offshore seismicity that occurs between the OBS network and the Hawaii Volcano Observatory's land based network. Although this study occurred during a time of volcanic quiescence for Lo';ihi, it establishes a basis for background seismicity of the volcano. More than 480 earthquakes were located using the OBS network, incorporating data from the HVO network where possible. Here we present relocated hypocenters using the double-difference earthquake location algorithm HypoDD (Waldhauser & Ellsworth, 2000), as well as tomographic images for a 30 km square area around the summit of Lo';ihi. Illuminated by using the double-difference earthquake location algorithm HypoDD (Waldhauser & Ellsworth, 2000), offshore seismicity during this study is punctuated by events locating in the mantle fault zone 30-50km deep. These events reflect rupture on preexisting faults in the lower lithosphere caused by stresses induced by volcano loading and flexure of the Pacific Plate (Wolfe et al., 2004; Pritchard et al., 2007). Tomography was performed using the double-difference seismic tomography method TomoDD (Zhang & Thurber, 2003) and showed overall velocities to be slower than

    Non-Helicobacter pylori helicobacters (NHPHs) besides H. pylori infect human stomachs and cause chronic gastritis and mucosa-associated lymphoid tissue lymphoma. Cholesteryl-α-glucosides have been identified as unique glycolipids present in H. pylori and some Helicobacter species. Cholesterol-α-glucosyltransferase (αCgT), a key enzyme for the biosynthesis of cholesteryl-α-glucosides, plays crucial roles in the pathogenicity of H. pylori. Therefore, it is important to examine αCgTs of NHPHs. Six gastric NHPHs were isolated from Japanese patients and maintained in mouse stomachs. The αCgT genes were amplified by PCR and inverse PCR. We retrieved the αCgT genes of other Helicobacter species by BLAST searches in GenBank. αCgT genes were present in most Helicobacter species and in all Japanese isolates examined. However, we could find no candidate gene for αCgT in the whole genome of Helicobacter cinaedi and several enterohepatic species. Phylogenic analysis demonstrated that the αCgT genes of all Japanese isolates show high similarities to that of a zoonotic group of gastric NHPHs including Helicobacter suis, Helicobacter heilmannii, and Helicobacter ailurogastricus. Of 6 Japanese isolates, the αCgT genes of 4 isolates were identical to that of H. suis, and that of another 2 isolates were similar to that of H. heilmannii and H. ailurogastricus. All gastric NHPHs examined showed presence of αCgT genes, indicating that αCgT may be beneficial for these helicobacters to infect human and possibly animal stomachs. Our study indicated that NHPHs could be classified into 2 groups, NHPHs with αCgT genes and NHPHs without αCgT genes. © 2017 John Wiley & Sons Ltd.

    Full Text Available We sought to examine sex-related differences in the characteristics and outcome in patients presenting with acute symptomatic pulmonary embolism (PE.We conducted a retrospective cohort study of 2,096 patients diagnosed with acute PE. The characteristics were recorded at presentation. Treatment was at the discretion of patients' physicians. The primary study outcome, all-cause mortality, and the secondary outcomes of PE-specific mortality, recurrent venous thromboembolism, and major bleeding were assessed during the first month of follow-up after PE diagnosis.Overall, the women were older than the men and had significantly higher rates of immobilization. They had significantly lower rates of chronic obstructive pulmonary disease and cancer. Women had a higher prevalence of syncope and elevated brain natriuretic peptide levels. Thirty-day all-cause mortality was similar between women and men (7.1% versus 6.2%; P = 0.38. Male gender was not independently significantly associated with PE-related death (adjusted odds ratio [OR] 1.02; 95% CI, 0.50 to 2.07; P = 0.96. Restricting the analyses to haemodynamically stable patients (n = 2,021, female gender was an independent predictor of all-cause (adjusted OR 1.56; 95% CI, 1.07 to 2.28; P = 0.02 and PE-specific mortality (adjusted OR 1.85; 95% CI, 1.02 to 3.33; P = 0.04. Compared with men, women were 2.05 times more likely to experience a major bleed.Women and men with PE had different clinical characteristics, presentation, and outcomes. Women receiving anticoagulation have a significantly higher risk of major bleeding, suggesting the need for careful monitoring of anticoagulant intensity in women.

    Full Text Available Abstract Background The structure of health care in Greece is receiving increased attention to improve its cost-effectiveness. We sought to examine the epidemiological characteristics of patients presenting to the vascular emergency department of a Greek tertiary care hospital during a 2-year period. We studied all patients presenting to the emergency department of vascular surgery at Red Cross Hospital, Athens, Greece between 1st January 2009 and 31st December 2010. Results Overall, 2452 (49.4% out of 4961 patients suffered from pathologies that should have been treated in primary health care. Only 2509 (50.6% needed vascular surgical intervention. Conclusions The emergency department of vascular surgery in a Greek tertiary care hospital has to treat a remarkably high percentage of patients suitable for the primary health care level. These results suggest that an improvement in the structure of health care is needed in Greece.

    Full Text Available Abstract Background Early diagnosis of HIV infection can prevent morbidity and mortality as well as reduce HIV transmission. The aim of the present study was to assess prevalence, describe trends and identify factors associated with late presentation of HIV infection in Barcelona (Spain during the period 2001-09. Methods Demographic and epidemiological characteristics of cases reported to the Barcelona HIV surveillance system were analysed. Late presentation was defined for individuals with a CD4 count below 350 cells/ml upon HIV diagnosis or diagnosis of AIDS within 3 months of HIV diagnosis. Multivariate logistic regression were used to identify predictors of late presentation. Results Of the 2,938 newly diagnosed HIV-infected individuals, 2,507 (85,3% had either a CD4 cell count or an AIDS diagnosis available. A total of 1,139 (55.6% of the 2,507 studied cases over these nine years were late presenters varying from 48% among men who have sex with men to 70% among heterosexual men. The proportion of late presentation was 62.7% in 2001-2003, 51.9% in 2004-2005, 52.6% in 2006-2007 and 52.1% in 2008-2009. A decrease over time only was observed between 2001-2003 and 2004-2005 (p = 0.001 but remained constant thereafter (p = 0.9. Independent risk factors for late presentation were older age at diagnosis (p Conclusion Late presentation of HIV is still too frequent in all transmission groups in spite of a strong commitment with HIV prevention in our city. It is necessary to develop interventions that increase HIV testing and facilitate earlier entry into HIV care.

    Our aim was to summarise the clinical characteristics and presentation of ameloblastomas in eastern Nigeria. We organised a retrospective study of 240 patients who presented with ameloblastomas to the Oral and Maxillofacial Surgery units of five specialist hospitals in the eastern states of Nigeria over an eight-year period (2004-2011). We analysed the casenotes, and categorised the cases by site of tumour, age, sex, and time of presentation. There were 117 men (49%) (mean (SD) age 43 (6.2) years) and 123 women (51%) (mean (SD) age 32 (4.7) years), a male:female ratio of 1:1.1. The largest age group was 20-39 years (n=102, 43%), and the most common site was the anterior mandible (n=140, 58%). Most of the patients presented late. Our results show that the most common site of ameloblastomas in Eastern Nigeria is the anterior mandible and that women are affected more than men, which is at variance with the results of most other studies.

    2009-02-01

    Full Text Available Abstract WAGR syndrome (Wilms' tumor, aniridia, genitourinary abnormalities and mental retardation and Potocki-Shaffer syndrome are rare contiguous gene deletion syndromes caused by deletions of the 11p14-p12 chromosome region. We present a patient with mental retardation, unilateral cataract, bilateral ptosis, genital abnormalities, seizures and a dysmorphic face. Cytogenetic analysis showed a deletion on 11p that was further characterized using FISH and MLPA analyses. The deletion (11p13-p12 located in the area between the deletions associated with the WAGR and Potocki-Shaffer syndromes had a maximum size of 8.5 Mb and encompasses 44 genes. Deletion of WT1 explains the genital abnormalities observed. As PAX6 was intact the cataract observed cannot be explained by a deletion of this gene. Seizures have been described in Potocki-Shaffer syndrome while mental retardation has been described in both WAGR and Potocki-Shaffer syndrome. Characterization of this patient contributes further to elucidate the function of the genes in the 11p14-p12 chromosome region.

    The objective of the study is to describe distinguishing characteristics of commercial sexual exploitation of children/child sex trafficking victims (CSEC) who present for health care in the pediatric setting. This is a retrospective study of patients aged 12-18 years who presented to any of three pediatric emergency departments or one child protection clinic, and who were identified as suspected victims of CSEC. The sample was compared with gender and age-matched patients with allegations of child sexual abuse/sexual assault (CSA) without evidence of CSEC on variables related to demographics, medical and reproductive history, high-risk behavior, injury history and exam findings. There were 84 study participants, 27 in the CSEC group and 57 in the CSA group. Average age was 15.7 years for CSEC patients and 15.2 years for CSA patients; 100% of the CSEC and 94.6% of the CSA patients were female. The two groups significantly differed in 11 evaluated areas with the CSEC patients more likely to have had experiences with violence, substance use, running away from home, and involvement with child protective services and/or law enforcement. CSEC patients also had a longer history of sexual activity. Adolescent CSEC victims differ from sexual abuse victims without evidence of CSEC in their reproductive history, high risk behavior, involvement with authorities, and history of violence.

    Aldehyde oxidases (AOXs) are molybdoflavoenzymes with an important role in the metabolism and detoxification of heterocyclic compounds and aliphatic as well as aromatic aldehydes. The enzymes use oxygen as the terminal electron acceptor and produce reduced oxygen species during turnover. Four different enzymes, mAOX1, mAOX3, mAOX4, and mAOX2, which are the products of distinct genes, are present in the mouse. A direct and simultaneous comparison of the enzymatic properties and characteristics of the four enzymes has never been performed. In this report, the four catalytically active mAOX enzymes were purified after heterologous expression in Escherichia coli The kinetic parameters of the four mouse AOX enzymes were determined and compared with the use of six predicted substrates of physiologic and toxicological interest, i.e., retinaldehyde, N 1 -methylnicotinamide, pyridoxal, vanillin, 4-(dimethylamino)cinnamaldehyde ( p- DMAC), and salicylaldehyde. While retinaldehyde, vanillin, p- DMAC, and salycilaldehyde are efficient substrates for the four mouse AOX enzymes, N 1 -methylnicotinamide is not a substrate of mAOX1 or mAOX4, and pyridoxal is not metabolized by any of the purified enzymes. Overall, mAOX1, mAOX2, mAOX3, and mAOX4 are characterized by significantly different K M and k cat values for the active substrates. The four mouse AOXs are also characterized by quantitative differences in their ability to produce superoxide radicals. With respect to this last point, mAOX2 is the enzyme generating the largest rate of superoxide radicals of around 40% in relation to moles of substrate converted, and mAOX1, the homolog to the human enzyme, produces a rate of approximately 30% of superoxide radicals with the same substrate.

    This is the first study to systematically investigate the characteristics of the water obtained by dewatering cyanobacteria-containing sludge generated in the drinking water treatment plant, including formation of C- and N-disinfection by-products (DBPs). Results showed that this 'dewatering water' (DW) had different properties when the sludge was stored at different times. The content of dissolved organic matter (DOM) and microcystins (MCs) in the DW were low when the sludge was treated or disposed of within 4 days; correspondingly, the C-, N-DBP production was also low. However, due to the damage of algal cells to some extent, the DOM and MC levels increased significantly for storage time longer than 4 days; the production of C-, N-DBPs also increased. There were also obvious differences in the characteristics of the DW from sludges generated with different coagulant species. Due to the better protective effect of FeCl 3 and polymeric aluminium ferric chloride (PAFC) flocs, the DOM and MC levels and the production of C-, N-DBPs in the DW with FeCl 3 and PAFC coagulation were lower than those with AlCl 3 coagulation, even though the sludges were stored for the same amount of time. Furthermore, because of the formation of Al and Fe hydroxides, precipitated onto the surface of flocs, the soluble Al and Fe in the DW decreased with increased storage time, especially in the first four days. Overall, this study revealed the trends in variation of DW quality for cyanobacteria-containing sludges formed with different coagulants, then FeCl 3 and PAFC coagulants are recommended and sludge should be treated or disposed of within 4 days.

    Inaba, Hideo; Morita, Shin-Ichi

    This paper deals with flow and cold heat storage characteristics of the oil (tetradecane, C14H30, freezing point 278.9 K, Latent heat 229 kJ/kg)/water emulsion as a latent heat storage material having a low melting point. The test emulsion includes a water-urea solution as a continuum phase. The freezing point depression of the continuum phase permits enhancement of the heat transfer rate of the emulison, due to the large temperature difference between the latent heat storage material and water-urea solution. The velocity of emulsion flow and the inlet temperature of coolant in a coiled double tube heat exchanger are chosen as the experimental parameters. The pressure drop, the heat transfer coefficient of the emulsion in the coiled tube are measured in the temperture region over solid and liquid phase of the latent heat storage material. The finishing time of the cold heat storage is defined experimentally in the range of sensible and latent heat storage. It is clarified that the flow behavior of the emulsion as a non-Newtonian fluid has an important role in cold heat storage. The useful nondimentional correlation equations for the additional pressure loss coefficient, the heat transfer coefficient and the finishing time of the cold heat storage are derived in terms of Dean number and heat capacity ratio.

    Abstract Objective The purpose of this article was to systematically review the literature on stimulant and atomoxetine combination therapy, in particular: 1) Characteristics of patients with attention-deficit/hyperactivity disorder (ADHD) given combination therapy, 2) treatment strategies used, 3) efficacy and effectiveness, and 4) safety and tolerability. Methods Literature databases (MEDLINE®, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index Expanded, and SciVerse Scopus) were systematically searched using prespecified criteria. Publications describing stimulant and atomoxetine combination therapy in patients with ADHD or healthy volunteers were selected for review. Exclusion criteria were comorbid psychosis, bipolar disorder, epilepsy, or other psychiatric/neurologic diseases that could confound ADHD symptom assessment, or other concomitant medication(s) to treat ADHD symptoms. Results Of the 16 publications included for review, 14 reported findings from 3 prospective studies (4 publications), 7 retrospective studies, and 3 narrative reviews/medication algorithms of patients with ADHD. The other two publications reported findings from two prospective studies of healthy volunteers. The main reason for prescribing combination therapy was inadequate response to previous treatment. In the studies of patients with ADHD, if reported, 1) most patients were children/adolescents and male, and had a combined ADHD subtype; 2) methylphenidate was most often used in combination with atomoxetine for treatment augmentation or switch; 3) ADHD symptom control was improved in some, but not all, patients; and 4) there were no serious adverse events. Conclusions Published evidence of the off-label use of stimulant and atomoxetine combination therapy is limited because of the small number of publications, heterogeneous study designs (there was only one prospective, randomized controlled trial), small sample sizes, and geographic bias.

    To provide more reliable data on the epidemiology of chronic myeloid leukaemia (CML) in Spain than are currently available. The EUTOS population-based project of European LeukemiaNet is a population registry of new CML cases in patients 18 years of age or older from 22 European areas. The Spanish section included the autonomous communities of Madrid, Castilla-La Mancha and Aragon, from 1-2-2010 to 31-12-2012. A total of 250 cases were recorded in 35 months. The overall incidence was 1.08 cases/10(5) inhabitants-year, with a predominance of men (58%) and clear differences among the communities. The incidence standardised by age was similar (overall, 1.04; men, 1.31; women, 0.81). The median age was 54 years. The incidence increased with age, reaching a peak at>65 years, although 31.7% of cases appeared between the ages of 20 and 44 years. Four percent of cases were diagnosed in advanced stages (2.4% in accelerated phase, 1.6% in blast crisis), 56% were asymptomatic, 38% had splenomegaly, and the Sokal score was high in 11% (lower than what was previously reflected in the literature). The current incidence of CML in Spain is higher than previously reported and similar to that of the European studies. Unlike the classical descriptions, CML presented mostly in asymptomatic form, with no splenomegaly, less leucocytosis and in stages with better prognosis.

    2003-01-01

    The aim of the BIOCLIM project is to develop and present techniques that can be used to develop self-consistent patterns of possible future climate changes over the next million years (climate scenarios), and to demonstrate how these climate scenarios can be used in assessments of the long-term safety of nuclear waste repository sites. Within the project, two strategies are implemented to predict climate change. The first is the hierarchical strategy, in which a hierarchy of climate models is used to investigate the evolution of climate over the period of interest. These models vary from very simple 2-D and threshold models, which simulate interactions between only a few aspects of the earth system, through general circulation models (GCMs) and vegetation models, which simulate in great detail the dynamics and physics of the atmosphere, ocean, and biosphere, to regional models, which focus in particular on the European region and the specific areas of interest. The second strategy is the integrated strategy, in which intermediate complexity climate models are developed, and used to consecutively simulate the development of the earth system over many millennia. Although these models are relatively simple compared to a GCM, they are more advanced than 2D models, and do include physical descriptions of the biosphere, cryo-sphere, atmosphere and ocean. This deliverable, D4/5, focuses on the hierarchical strategy, and in particular the GCM and vegetation model simulation of possible future climates. Deliverable D3 documented the first step in this strategy. The Louvain-la-Neuve 2-D climate model (LLN-2D) was used to estimate (among other variables) annual mean temperatures and ice volume in the Northern Hemisphere over the next 1 million years. It was driven by the calculated evolution of orbital parameters, and plausible scenarios of CO 2 concentration. From the results, 3 future time periods within the next 200,000 years were identified as being extreme, that is

    Brekke, A.

    1983-01-01

    This chapter discusses the relationship between the interplanetary magnetic field (IMF) and various polar cap current systems, such as the DP2-system and the S /SUB q/ P-system. The disagreements concerning these systems are examined. Topics considered include the polar cap (a result of an open magnetosphere); studies of the polar cap magnetic field variations; the DP2-current system and its relation to the IMF; the polar cap current system during a northward IMF; the azimuthal component of IMF and its influence on the polar cap magnetic field variations; the electric potential distribution on the polar cap; rocket observations of the polar cap electric field; the auroral arcs as a visible trace of the ionospheric convection; neutral wind measurements in the polar cap F-region; and further studies of polar cap dynamics. The focus is on the polar region inside the auroral oval. It is suggested that more research is needed of the polar cap current system in order to understand the magnetosphereionosphere coupling, with the polar cap ionospheric conductivity distribution being the most crucial parameter

    To know the variables present in primary and secondary school students who do not smoke or intend to smoke from a positive health model. Cross-sectional study with 482 students from Andalusia and Catalonia using a validated questionnaire (ESFA and PASE project). Binary logistic regression analysis was performed. Those who did not intend to smoke viewed smoking unfavourably and had high self-efficacy (p <0.001). In non-consumers, the most associated variables were attitude, social model (p <0.001), and self-efficacy (p =0.005). The results show motivational factors present in students who do not smoke and do not intend to do so. Attitude and self-efficacy are strongly associated with intention and behaviour. This information might be useful for developing positive health promotion strategies from a salutogenesis approach. Copyright © 2018 SESPAS. Publicado por Elsevier España, S.L.U.

  14. Cryopreservation does not alter main characteristics of Good Manufacturing Process-grade human multipotent mesenchymal stromal cells including immunomodulating potential and lack of malignant transformation.

    The immunomodulating capacity of multipotent mesenchymal stromal cells (MSCs) qualifies them as a therapeutic tool in several diseases. However, repeated transplantation with products of reproducible characteristics may be required. This could be achieved with cryopreserved aliquots of Good Manufacturing Practice (GMP)-grade MSCs. However, the impact of cryopreservation on the characteristics of GMP-MSCs is ill defined. We produced fresh and cryopreserved MSCs from human donors with a xenogen-free GMP protocol. Immunogenicity and immunomodulating capacity were tested in co-culture with putative recipient-specific peripheral blood mononuclear cells (PBMCs). Risk of malignant transformation was assessed in vitro and in vivo. Cryopreservation had no impact on viability and consensus criteria of MSCs. In co-culture with PBMCs, MSCs showed low immunogenicity and suppressed mitogen-stimulated proliferation of PBMC irrespective of cryopreservation. Cytogenetic aberrations were not observed consistently in fresh and cryopreserved products, and no signs of malignant transformation occurred in functional assays. MSC products from an elderly pretreated donor showed reduced functional quality, but imminent failure of functional criteria could be detected by an increased population doubling time in early passages. This study is the first systematic analysis on cryopreservation of xenogen-free human bone marrow-derived GMP-MSCs. The data support that cryopreservation does not alter the characteristics of the cells and thus may allow the generation of products for serial transplantation. In addition, the protocol allowed early detection of MSC products with low functional capacity. Copyright © 2015 International Society for Cellular Therapy. Published by Elsevier Inc.

    Regional hydrological modeling in ungauged regions has attracted growing attention in water resources research. The southern Tibetan Plateau often suffers from data scarcity in watershed hydrological simulation and water resources assessment. This hinders further research characterizing the water cycle and solving international water resource issues in the area. In this study, a multi-spatial data based Distributed Time-Variant Gain Model (MS-DTVGM) is applied to the Yarlung Zangbo River basin, an important international river basin in the southern Tibetan Plateau with limited meteorological data. This model is driven purely by spatial data from multiple sources and is independent of traditional meteorological data. Based on the methods presented in this study, daily snow cover and potential evapotranspiration data in the Yarlung Zangbo River basin in 2050 are obtained. Future (2050) climatic data (precipitation and air temperature) from the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR5) are used to study the hydrological response to climate change. The result shows that river runoff will increase due to precipitation and air temperature changes by 2050. Few differences are found between daily runoff simulations from different Representative Concentration Pathway (RCP) scenarios (RCP2.6, RCP4.5 and RCP8.5) for 2050. Historical station observations (1960-2000) at Nuxia and model simulations for two periods (2006-2009 and 2050) are combined to study inter-annual and intra-annual runoff distribution and variability. The inter-annual runoff variation is stable and the coefficient of variation (CV) varies from 0.21 to 0.27. In contrast, the intra-annual runoff varies significantly with runoff in summer and autumn accounting for more than 80% of the total amount. Compared to the historical period (1960-2000), the present period (2006-2009) has a slightly uneven intra-annual runoff temporal distribution, and becomes more balanced in

    Changes in the quality attributes of non-centrifugal cane brown sugar represented by physicochemical characteristics as well as flavour components and Maillard reaction products (MRPs) were monitored every 3 months over 1 year of storage. Stored cane brown sugar became darker, and its moisture content and water activity (a(w)) increased during storage. Fructose and glucose levels decreased as non-enzymatic browning via the Maillard reaction occurred in the stored sample, and a similar trend was also discovered in aconitic and acetic acids. Stored cane brown sugar lost its acidic and sulfuric odours (58.70-39.35% and 1.85-0.08%, respectively); subsequently, the nutty and roasted aroma increased from 26.52% to 38.59% due to the volatile MRPs. The browning rate of stored cane brown sugar was positively associated with the development of volatile MRPs (Pearson's coefficient = 0.860), whereas the amount of 3-deoxyglucosone, an intermediate product of the Maillard reaction, had a lower association with the brown colour due to its relatively slow degradation rate.

    The comparison of clinical cancer research characteristics across the Atlantic and their evolution over time have not been studied to date. We collected oral presentations on breast, lung and colorectal cancer at ASCO (n=506) and ESMO (n=239) Congresses in years 2000-2010. EU-originated research constituted 52% of all ASCO presentations while US-research 26.7% of ESMO Congress presentations. Industry sponsorship was reported in 24.8% of ASCO vs. 31.8% of ESMO Congress trials. ASCO-presented trials were larger with longer follow-up periods but were blinded less often. ESMO-presented trials used Event-Free Survival (EFS, 38.1%) and Surrogate (18.4%) primary endpoints and reported positive primary endpoints (65%) more often than ASCO-presented trials. Interim analysis resulted in discontinuation of a trial more often at ASCO Congress (8.3% vs. 3.2%). ASCO Congress-presented research was more often published (69.2% vs. 59.8% at ESMO) at higher impact factor journals. Strong trends over the decade were seen for more frequent industry sponsorship, blinded design, larger sample size, early interim discontinuation, use of EFS endpoints and biomarker evaluation. Cancer clinical research is a complex scientific activity with common global but also distinct characteristics at the two sides of the Atlantic. Copyright © 2011 Elsevier Ltd. All rights reserved.

The study of S. aureus prevalence, antimicrobial resistance and clonal lineages in humans, animals and food in African settings has great relevance, taking into consideration the high diversity of ethnicities, cultures and food habits that determine the lifestyle of the people. Little is known about milk carriage of methicillin resistant S. aureus strains (MRSA) and their virulence factors in Uganda. Here, we present the prevalence of MRSA in bulk can milk and raw milk products in pastoral communities of south-west Uganda. We also present PFGE profiles, spa-types, as well as frequency of enterotoxins genes. S. aureus was identified by the coagulase test, susceptibility testing by the Kirby-Bauer disc diffusion and E-test methods and MRSA by detection of the mecA gene and SCCmec types. The presence of Panton - Valentine Leucocidin (PVL) genes and staphylococcal enterotoxins was determined by PCR, while genotyping was by PFGE and spa typing. S. aureus were isolated from 30/148 (20.3%) milk and 11/91(12%) sour milk samples. mecA gene carriage, hence MRSA, was detected in 23/41 (56.1%) of the isolates, with 21 of the 23 (91.3%) being SCCmec type V; while up to 30/41 (73.2%) of the isolates were resistant to tetracycline. Only five isolates carried the PVL virulence gene, while PFGE typing revealed ten clusters (ranging from two seven isolates each) that comprised 83% of the sample, and only eight isolates with unique pulsotypes. The largest PFGE profile (E) consisted of seven isolates while t7753, t1398, and t2112 were the most common spa-types. Thirty seven of the 41 strains (90.2%) showed at least one of the eight enterotoxin genes tested, with sem 29 (70.7%), sei 25 (61%) and seg 21 (51.2%) being the most frequently observed genes. This

    The MTF, NNPS, and DQE are standard linear system metrics used to characterize intrinsic detector performance. To evaluate total system performance for actual clinical conditions, generalized linear system metrics (GMTF, GNNPS and GDQE) that include the effect of the focal spot distribution, scattered radiation, and geometric unsharpness are more meaningful and appropriate. In this study, a two-dimensional (2D) generalized linear system analysis was carried out for a standard flat panel detector (FPD) (194-micron pixel pitch and 600-micron thick CsI) and a newly-developed, high-resolution, micro-angiographic fluoroscope (MAF) (35-micron pixel pitch and 300-micron thick CsI). Realistic clinical parameters and x-ray spectra were used. The 2D detector MTFs were calculated using the new Noise Response method and slanted edge method and 2D focal spot distribution measurements were done using a pin-hole assembly. The scatter fraction, generated for a uniform head equivalent phantom, was measured and the scatter MTF was simulated with a theoretical model. Different magnifications and scatter fractions were used to estimate the 2D GMTF, GNNPS and GDQE for both detectors. Results show spatial non-isotropy for the 2D generalized metrics which provide a quantitative description of the performance of the complete imaging system for both detectors. This generalized analysis demonstrated that the MAF and FPD have similar capabilities at lower spatial frequencies, but that the MAF has superior performance over the FPD at higher frequencies even when considering focal spot blurring and scatter. This 2D generalized performance analysis is a valuable tool to evaluate total system capabilities and to enable optimized design for specific imaging tasks.

    Chronic pelvic pain is a debilitating condition. It is unknown if there is a clinical phenotype for adhesive disorders. This study aimed to determine if the presence or absence, nature, severity and extent of adhesions correlated with demographic and patient reported clinical characteristics of women presenting with CPP. Women undergoing a laparoscopy for the investigation of chronic pelvic pain were recruited prospectively; their pain and phenotypic characteristics were entered into a hierarchical cluster analysis. The groups with differing baseline clinical and operative characteristics in terms of adhesions involvement were analyzed. Sixty two women were recruited where 37 had adhesions. A low correlation was found between women's reported current pain scores and that of most severe (r = 0.34) or average pain experienced (r = 0.44) in the last 6 months. Three main groups of women with CPP were identified: Cluster 1 (n = 35) had moderate severity of pain, with poor average and present pain intensity; Cluster 2 (n = 14) had a long duration of symptoms/diagnosis, the worst current pain and worst physical, emotional and social functions; Cluster 3 (n = 11) had the shortest duration of pain and showed the best evidence of coping with low (good) physical, social and emotional scores. This cluster also had the highest proportion of women with adhesions (82%) compared to 51% in Cluster 1 and 71% in Cluster 2. In this study, we found that there is little or no correlation between patient-reported pain, physical, emotional and functional characteristics scores with the presence or absence of intra-abdominal/pelvic adhesions found during investigative laparoscopy. Most women who had adhesions had the lowest reported current pain scores.

    To date there has been limited published data presenting the characteristics and timeliness of the management in an Emergency Department (ED) for culturally and linguistically diverse (CALD) patients presenting with chest pain. This study aimed to describe the presenting characteristics and processing times for CALD patients with chest pain compared to the Australian-born population, and current guidelines. This study was a cross sectional analysis of a cohort of patients who presented with chest pain to the metropolitan hospital between 1 July 2012 and 30 June 2014. Of the total study population (n=6640), 1241 (18.7%) were CALD and 5399 (81.3%) were Australian-born. CALD patients were significantly older than Australian-born patients (mean age 62 vs 56years, p<0.001). There were no differences in the proportion of patients who had central chest pain (74.9% vs 75.7%, p=0.526); ambulance utilisation (41.7% vs 41.1%, p=0.697); and time to initial treatment in ED (21 vs 22min, p=0.375). However, CALD patients spent a significantly longer total time in ED (5.4 vs 4.3h, p<0.001). There was no difference in guideline concordance between the two groups with low rates of 12.5% vs 13%, p=0.556. Nonetheless, CALD patients were 22% (95% CI, 0.65, 0.95, p=0.015) less likely to receive the guideline management for chest pain. The initial emergency care was equally provided to all patients in the context of a low rate of concordance with three chest pain related standards from the two guidelines. Nonetheless, CALD patients spent a longer time in ED compared to the Australian-born group. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background People who present to hospital after intentionally harming themselves pose a common and important problem. Previous reviews of interventions have been inconclusive as existing trials have been under powered and done on unrepresentative populations. These reviews have however indicated that problem solving therapy and regular written communications after the self-harm attempt may be an effective treatment. This protocol describes a large pragmatic trial of a package of measures which include problem solving therapy, regular written communication, patient support, cultural assessment, improved access to primary care and a risk management strategy in people who present to hospital after self-harm using a novel design. Methods We propose to use a double consent Zelen design where participants are randomised prior to giving consent to enrol a large representative cohort of patients. The main outcome will be hospital attendance following repetition of self-harm, in the 12 months after recruitment with secondary outcomes of self reported self-harm, hopelessness, anxiety, depression, quality of life, social function and hospital use at three months and one year. Discussion A strength of the study is that it is a pragmatic trial which aims to recruit large numbers and does not exclude people if English is not their first language. A potential limitation is the analysis of the results which is complex and may underestimate any effect if a large number of people refuse their consent in the group randomised to problem solving therapy as they will effectively cross over to the treatment as usual group. However the primary analysis is a true intention to treat analysis of everyone randomised which includes both those who consent and do not consent to participate in the study. This provides information about how the intervention will work in practice in a representative population which is a major advance in this study compared to what has

    Changes to the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) incorporate the inclusion or modification of six disorders: Autism Spectrum Disorder, Social Anxiety Disorder, Intermittent Explosive Disorder, Disruptive Mood Dysregulation Disorder, Avoidant/Restrictive Food Intake Disorder and Binge Eating Disorder. The objectives of this study were to assess the construct validity and parent-child agreement of these six disorders in the Spanish language Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version (K-SADS-PL-5) in a clinical population of children and adolescents from Latin America. The Spanish version of the K-SADS-PL was modified to integrate changes made to the DSM-5. Clinicians received training in the K-SADS-PL-5 and 90% agreement between raters was obtained. A total of 80 patients were recruited in four different countries in Latin America. All items from each of the six disorders were included in a factor analysis. Parent-child agreement was calculated for every item of the six disorders, including the effect of sex and age. The factor analysis revealed 6 factors separately grouping the items defining each of the new or modified disorders, with Eigenvalues greater than 2. Very good parent-child agreements (r>0.8) were found for the large majority of the items (93%), even when considering the sex or age of the patient. This independent grouping of disorders suggests that the manner in which the disorders were included into the K-SADS-PL-5 reflects robustly the DSM-5 constructs and displayed a significant inter-informant reliability. These findings support the use of K-SADS-PL-5 as a clinical and research tool to evaluate these new or modified diagnoses. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available Abstract Background Maori, the indigenous people of New Zealand, who present to hospital after intentionally harming themselves, do so at a higher rate than non-Maori. There have been no previous treatment trials in Maori who self harm and previous reviews of interventions in other populations have been inconclusive as existing trials have been under powered and done on unrepresentative populations. These reviews have however indicated that problem solving therapy and sending regular postcards after the self harm attempt may be an effective treatment. There is also a small literature on sense of belonging in self harm and the importance of culture. This protocol describes a pragmatic trial of a package of measures which include problem solving therapy, postcards, patient support, cultural assessment, improved access to primary care and a risk management strategy in Maori who present to hospital after self harm using a novel design. Methods We propose to use a double consent Zelen design where participants are randomised prior to giving consent to enrol a representative cohort of patients. The main outcome will be the number of Maori scoring below nine on the Beck Hopelessness Scale. Secondary outcomes will be hospital repetition at one year; self reported self harm; anxiety; depression; quality of life; social function; and hospital use at three months and one year. Discussion A strength of the study is that it is a pragmatic trial which aims to recruit Maori using a Maori clinical team and protocol. It does not exclude people if English is not their first language. A potential limitation is the analysis of the results which is complex and may underestimate any effect if a large number of people refuse their consent in the group randomised to problem solving therapy as they will effectively cross over to the treatment as usual group. This study is the first randomised control trial to explicitly use cultural assessment and management. Trial

    This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group. Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011. Information extracted from case note review was used to grade patients using the Auckland Regional Grading Criteria. A total of 799 patients were included. The commonest symptoms were: rectal bleeding (25.5-42.3%) and change in bowel habit (20.6-26.8%). Low-risk symptoms including abdominal pain (16.3-46.8%) and weight loss (18.4-26.1%) were not uncommon. 64.4% of Maori and 64.9% of Pacific patients had stage III or IV cancers. Pacific patients had more stage IV disease, 37.7% (pAuckland Regional Grading Criteria would miss 24.7% of the patients with CRC in the referral population. While rectal bleeding and change in bowel habit are frequent presenting symptoms, low-risk atypical symptoms including constipation, weight loss and abdominal pain were not uncommon. Significant proportion of Pacific patients present with late-stage disease. The current Auckland Regional grading criteria would miss significant proportion of our study population with colorectal cancer.

    Full Text Available Objective: The primary objective of this study was to determine the sociodemographic and clinical characteristics of all persons who presented to the Accident and Emergency Department of the University Hospital of the West Indies with a history of deliberate harm over a six-month period. Methods: The dockets of patients presenting with deliberate self-harm were collected and reviewed for the information. A questionnaire was designed to extract the information. Data were analysed using SPSS version 17 and RXC programme. Results: Of the total number of dockets reviewed (n = 61, 78% of patients were below age 40 years, with a mean age of 28 years. Sixty-four per cent were female, 82% were single, 83% lived with someone, 80% had a secondary school level of education and 72% were unemployed. Overdose of medications was the main method of harm. Seventy-five per cent of patients did not use illicit substances. There was a significant association found between reason for self-harm and psychiatric illness (p < 0.001. Conclusion: Given these preliminary results, it would be useful to conduct a wider, island-wide study to determine the extent of self-harming behaviour in Jamaica so that appropriate interventions can be implemented to reduce this problem.

    There are no published data on factors impacting on acute respiratory illness (ARI) among urban Indigenous children. We describe the characteristics and respiratory risk profile of young urban Indigenous children attending an Aboriginal-friendly primary health-care practice. We conducted a cross-sectional analysis of data collected at baseline in a cohort study investigating ARI in urban Indigenous children aged less than 5 years registered with an Aboriginal primary health-care service. Descriptive analyses of epidemiological, clinical, environmental and cultural factors were performed. Logistic regression was undertaken to examine associations between child characteristics and the presence of ARI at baseline. Between February 2013 and October 2015, 180 Indigenous children were enrolled; the median age was 18.4 months (7.7-35), 51% were male. A total of 40 (22%) children presented for a cough-related illness; however, ARI was identified in 33% of all children at the time of enrolment. A total of 72% of children were exposed to environmental tobacco smoke. ARI at baseline was associated with low birthweight (adjusted odds ratio (aOR) 2.54, 95% confidence interval (CI) 1.08-5.94), a history of eczema (aOR 2.67, 95% CI 1.00-7.15) and either having a family member from the Stolen Generation (aOR 3.47, 95% CI 1.33-9.03) or not knowing this family history (aOR 3.35, 95% CI 1.21-9.26). We identified an urban community of children of high socio-economic disadvantage and who have excessive exposure to environmental tobacco smoke. Connection to the Stolen Generation or not knowing the family history may be directly impacting on child health in this community. Further research is needed to understand the relationship between cultural factors and ARI. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Many anesthesiologists in medical centers (MC) or in anesthesiologist-training hospitals (ATH) are accustomed to present their research data in the form of poster abstracts at the annual meetings of Taiwan Society of Anesthesiologists (TSA) to represent their academic gainings in a designated period of time. However, an orphaned P value without mentioning the related specified statistical test has frequently been found in these articles. The difference in presentation of statistical test after P value between MC/ATH and non-MC/non-ATH in recent three TSA consecutive annual meetings was explored in this article. We collected the proceedings handbooks of TSA annual meetings in a period spanning 3 yrs (2003 to 2005) and analyzed the hospital characteristic of first institute-byliner in the poster abstract. Data were analyzed with Fisher's exact test and statistical significance was assumed if P poster abstracts with byliners of 20 hospitals. Only 2 of the 20 hospitals were accredited as non-ATH and 4 as non-MC. There were 64 (63%) abstracts without specified statistical test after P value and no significant difference was found among each category. (P = 0.47 in ATH vs. non-ATH and P = 0.07 in MC vs. non-MC). The basic concept of P value with specified statistical test was not applicable comprehensively in poster abstracts of the annual conferences. Based on our wishful intention, we suggest that the anesthesia administrators and senior anesthesiologists at ATH or MC, and the members of the committee responsible for running academic affairs in TSA, should pay attention to this prodigy and work together to improve our basic statistics in poster presentation.

    To investigate the demographics, diagnoses and outcomes for new adult cancer patients with an initial presentation via the A&E or acute oncology teams. Patients with initial emergency presentation of malignancy have been documented to have poorer treatment outcomes and shorter survival. Patient level data on this subject is relatively limited with regard to the demographics, diagnoses and the clinical factors that may underlie late presentations. A 15 month audit of the patients presenting with a new diagnosis of malignancy was performed in 2011-2012. Data on demographics, diagnosis and outcome were assembled and analysed. The clinical data on emergency presentations were compared to reference information on the incidence and median age at presentation for each malignancy within the standard population. During the study a total of 178 new cancer patients presented via the A and E service. The most frequent diagnoses were lung cancer with 21% of cases and CNS and colorectal cancer each with 9% of cases. There was a higher incidence of emergency new presentations of lung cancer, CNS tumours, ovarian, pancreatic and testicular cancer than in the standard population, whilst breast cancer, bladder cancer and prostate cancer patients were under-represented. The median age at diagnosis was 74 and for a number of malignancies including CNS tumours, breast cancer, colorectal cancer and head and neck cancer the emergency cases presented at significantly greater ages than in the standard population. Overall 27% of patients were unfit or unsuitable for a diagnostic biopsy, this group had only a 3 month median survival compared to 14 months for those suitable for biopsy and treatment. Despite a wide range of initiatives, the emergency and late diagnosis of patients with metastatic cancer remains a significant challenge with many patients too advanced and unwell at presentation for active treatment. These patients tend to be older and have malignancies that present with either

    India is currently in the fourth stage of epidemiological transitions where cardiovascular disease is the leading cause of mortality and morbidity. Purpose of the present study was to assess the risk factors, clinical presentation, angiographic profile including severity, and in-hospital outcome of very young adults (aged ≤ 30 years) with first acute myocardial infarction (AMI). Total of 1,116 consecutive patients with ST-segment elevation acute myocardial infarction (STEMI) were studied between March 2013 and February 2015 at LPS Institute of Cardiology, Kanpur, Uttar Pradesh, India. Mean age of the patients was 26.3 years. Risk factors were smoking (78.5%), family history of premature coronary artery disease (CAD) (46.8%), obesity (39.1%), physical inactivity (38.7%) and stressful life events (29.6%). The most common symptom and presentation was chest pain and anterior wall myocardial infarction (AWMI) in 94.8% and 58.8%, respectively. About 80.6% of patients had obstructive CAD with single vessel disease (57.6%), double-vessel disease (12.9%) and left main involvement (3.2%). Left anterior descending (LAD) was commonest culprit artery (58.1%) followed by right coronary artery in 28.2%. In-hospital mortality was 2.8%. Percutaneous coronary intervention was performed in 71.6% of patients. Median number and length of stent were 1.18 and 28 ± 16 mm, respectively. AMI in very young adult occurred most commonly in male. Smoking was the most common risk factor. AWMI owing to LAD artery involvement was the most common presentation. Mean time of presentation after symptom onset was 16.9 hours. In contrast to western population, it is characterised by earlier onset, delayed presentation, more severity, diffuse disease, and more morbidity but with favourable in-hospital mortality.

These include contents about environmental education, but with scarce diffusion and low adhesion. If environmental education could force a detailed knowledge about regulations, its application could be demanded by community actions. Moreover, environmental education is considered in regulations as a fundamental tool for sustainable development. There is a profuse legislation in Argentina, with more than 3,000 legal instruments of different hierarchical order and jurisdictional level. Three argentine laws were studied and compared: Environmental General Law (national: Law 25,675; La Pampa Environmental Law (province order: Law 1,914; and Environmental Education Law of Buenos Aires (city order: Law 1,687.

    Heat flow and associated thermal regimes are related to the tectonic evolution and geophysical properties of the lithosphere. The Ordos Basin is located in a tectonic transitional zone: areas to the east of the basin are characterized as tectonically active, while regions to the west of the basin are characterized as tectonically stable. It is of general interest to learn the geothermal characteristics of the basin in such tectonic conditions. To clarify the spatial variability of the present-day geothermal field across the basin and its implications, we report 13 terrestrial heat flow points based on the first systematic steady-state deep borehole temperature measurements in the basin. The new data together with existing data show that the geothermal gradients in the basin range from 12.6 to 42.3 °C km-1 with a mean of 27.7 ± 5.3 °C km-1; the terrestrial heat flow values range from 43.3 to 88.7 mW m-2 with a mean of 64.7 ± 8.9 mW m-2. Such values are higher than those of typical cratonic basins and lower than those of tectonically active areas. By using all these data in the basin and adjacent areas, we plot geothermal gradient and heat flow distribution maps. The maps reveal that the basin is cooling westwards and northwards. The distribution pattern of the geothermal field is consistent with the lithospheric thickness variation in the basin. This similarity suggests that the geothermal spatial variability of the Ordos Basin is mainly influenced by heat from the deep mantle. In the southeastern basin, we locate a positive geothermal anomaly caused by the convergence of heat flow in basement highs and the high radiogenic heat production. In addition, the high heat flow in the eastern basin is related to the intense uplift during the Cenozoic Era.

    Full Text Available On the basis of the authors’ methodology, the models of productive potential of the Russian Federation regions, including estimations of intellectual capital, were constructed. It is shown that characteristics of well-being level and quality of life make a significant impact on the regional production’s efficiency. The characteristics of regions’ readiness to innovate are identified, it is possible to name it as a factor of production’s efficiency. It is shown that the inclusion of different factors of efficiency in the production potential model can significantly increase the differentiation of technical efficiency estimates, besides these estimates and their grades depend on a set of efficiency’s factors. On the basis of a comparison of real GRP and boundary GRP ratings, it is identified locally effective regions with a relatively high estimation of efficiency among regions with similar amounts of GRP and locally ineffective regions. It is calculated marginal effects of influence of the efficiency’s factors on the result of industrial activity in the region. It seems constructively to use these estimates while analyzing the prospects for regions’ development, which is based on the possibility of targeting impact on controllable efficiency’s factors. The article is also offered the option of methodology of the public policy efficiency estimation on the knowledge economy formation — an agent-based model for Russia, which is learning the “knowledge economy” sector and considering their relationship with the rest of the macroeconomic system.

    Full Text Available Leakage of electromagnetic fields (EMF from short-wave radiofrequency physiotherapeutic diathermies (SWDs may cause health and safety hazards affecting unintentionally exposed workers (W or general public (GP members (assisting patient exposed during treatment or presenting there for other reasons. Increasing use of electronic active implantable medical devices (AIMDs, by patients, attendants, and workers, needs attention because dysfunctions of these devices may be caused by electromagnetic interactions. EMF emitted by 12 SWDs (with capacitive or inductive applicators were assessed following international guidelines on protection against EMF exposure (International Commission on Nonionizing Radiation Protection for GP and W, new European directive 2013/35/EU for W, European Recommendation for GP, and European Standard EN 50527-1 for AIMD users. Direct EMF hazards for humans near inductive applicators were identified at a distance not exceeding 45 cm for W or 62 cm for GP, but for AIMD users up to 90 cm (twice longer than that for W and 50% longer than that for GP because EMF is pulsed modulated. Near capacitive applicators emitting continuous wave, the corresponding distances were: 120 cm for W or 150 cm for both—GP or AIMD users. This assessment does not cover patients who undergo SWD treatment (but it is usually recommended for AIMD users to be careful with EMF treatment.

    Full Text Available Discutimos a possibilidade da inserção da Gerontologia na Tabela das Áreas do Conhecimento do CNPq num cenário em essa tabela vem sendo questionada na comunidade científica, particularmente no que se refere à inclusão de áreas multidisciplinares. A partir de Foucault, entendemos a Árvore do Conhecimento como uma taxonomia, um continuum, onde todas as áreas são colocadas lado a lado, mais próximas ou mais afastadas conforme semelhanças e diferenças entre si. Trata-se de um tratamento linear e finito que estabelece que uma determinada área do conhecimento só pode estar situada num ponto da parte da linha que corresponde a uma grande área. A Gerontologia caracteristicamente multidisciplinar não alcançou lugar nessa taxonomia institucionalizada, seja porque haveria problemas em relação a conceitos, interesses e projeto político em sua constituição como área do conhecimento, seja porque a taxonomia seria incompatível com a multidisciplinaridade. Concluímos que é possível conceber uma nova Tabela de Campos de Conhecimentos e de Saberes e proceder visualizações dos estudos sobre o envelhecimento e sobre toda e qualquer região dos conhecimentos e dos saberes na plenitude de sua muldisciplinaridade e de suas transformações ao longo dos tempos.We discuss the possibility of including Gerontology in the CNPq Areas of Knowledge Table, in a scenario where this Table is being questioned by the scientific community, particularly with regard to the inclusion of multidisciplinary areas. Based on Foucault, we view the Tree of Knowledge as taxonomy, a continuum in which all areas are placed side by side, closer together or further apart, depending on their similarities and differences. This finite linear approach establishes that a certain Area of knowledge may be placed only at a point along the line corresponding to a Greater Area. Inherently multidisciplinary, gerontology has not been placed in this institutionalized taxonomy

    Full Text Available Background. Chronic pain (CP accounts for 10–16% of emergency department (ED visits, contributing to ED overcrowding and leading to adverse events. Objectives. To describe patients with CP attending the ED and identify factors contributing to their visit. Methods. We used a mixed-method design combining interviews and questionnaires addressing pain, psychological distress, signs of opioid misuse, and disability. Participants were adults who attended the EDs of a large academic tertiary care center for their CP problem. Results. Fifty-eight patients (66% women; mean age 46.5, SD = 16.9 completed the study. The most frequently cited reason (60% for ED visits was inability to cope with pain. Mental health problems were common, including depression (61% and anxiety (45%. Participants had questions about the etiology of their pain, concerns about severe pain-related impairment, and problems with medication renewals or efficacy and sometimes felt invalidated in the ED. Although most participants had a primary care physician, the ED was seen as the only or best option when pain became unmanageable. Conclusions. Patients with CP visiting the ED often present with complex difficulties that cannot be addressed in the ED. Better access to interdisciplinary pain treatment is needed to reduce the burden of CP on the ED.

    Purpose: At a time both when late complications and second malignancies have become a growing concern and when staging laparotomy has been largely abandoned and comparative studies for staging Hodgkin's disease by state of the art computed tomography (CT) vs. lymphangiography have revealed minimal differences in results for these procedures, our purpose for undertaking this study was twofold. Our initial reason was to determine and compare probabilities for negative abdominal findings for patients with Stage I presentations with those for patients with Stage II as determined by lymphangiography and subsequently by laparotomy for those patients who had negative lymphangiograms. Our second reason, being an extension of the first, was to create a resource that can be used in conjunction with other information for arriving at appropriate treatment decisions including giving either more or particularly less than standard institutional therapy and especially with respect to the abdomen. Methods and Materials: Data on 714 patients with prelymphangiogram Stage I-II upper torso presentations of Hodgkin's disease were entered prospectively in our database between 1968 and 1987. Twenty-eight with lymphocyte predominant disease, who had both negative lymphangiogram and negative laparotomy findings and 17 with questionable diagnoses of lymphocyte-depleted or unclassified disease were excluded from subsequent analyses of 669 patients with nodular sclerosis (NS) and mixed cellularity (MC) diagnoses. Results: Stage I: in final logistic models, negative lymphangiogram findings were associated strongly with a combination of no constitutional symptoms and nodular sclerosis histology, whereas negative laparotomy findings correlated strongly with a combination of no constitutional symptoms and female sex. Predicted probabilities depended on the ratios of favorable to unfavorable characteristics. Stage II: in final logistic models, negative lymphangiogram findings were associated

    In this study, we evaluated the imaging characteristics of the high-resolution, high-sensitivity micro-angiographic fluoroscope (MAF) with 35-micron pixel-pitch when used with different commercially-available 300 micron thick phosphors: the high resolution (HR) and high light (HL) from Hamamatsu. The purpose of this evaluation was to see if the HL phosphor with its higher screen efficiency could be replaced with the HR phosphor to achieve improved resolution without an increase in noise resulting from the HR's decreased light-photon yield. We designated the detectors MAF-HR and MAF-HL and compared them with a standard flat panel detector (FPD) (194 micron pixel pitch and 600 micron thick CsI(Tl)). For this comparison, we used the generalized linear-system metrics of GMTF, GNNPS and GDQE which are more realistic measures of total system performance since they include the effect of scattered radiation, focal spot distribution, and geometric un-sharpness. Magnifications (1.05-1.15) and scatter fractions (0.28 and 0.33) characteristic of a standard head phantom were used. The MAF-HR performed significantly better than the MAF-HL at high spatial frequencies. The ratio of GMTF and GDQE of the MAF-HR compared to the MAF-HL at 3(6) cycles/mm was 1.45(2.42) and 1.23(2.89), respectively. Despite significant degradation by inclusion of scatter and object magnification, both MAF-HR and MAF-HL provide superior performance over the FPD at higher spatial frequencies with similar performance up to the FPD's Nyquist frequency of 2.5 cycles/mm. Both substantially higher resolution and improved GDQE can be achieved with the MAF using the HR phosphor instead of the HL phosphor.

    The Accreditation Council for Graduate Medical Education requires scholarly activity within general surgery residency programs. The association between in-training research presentations and postgraduation publications is unknown. We hypothesized that surgical trainee presentations at an American College of Surgeons (ACS) state chapter meeting resulted in peer-reviewed publications and future scholarly activity. The ACS Wisconsin state chapter meeting agendas from 2000 to 2014 were reviewed to identify all trainees who delivered podium presentations. A literature search was completed for subsequent publications. Program coordinators were queried and an electronic search was performed to determine practice location and type for each residency graduate. Wisconsin state chapter ACS meeting. General surgery residents, fellows, and medical students in Wisconsin. There were 288 podium presentations by trainees (76% residents, 20% medical students, and 4% fellows). Presentations were clinical (79.5%) and basic science (20.5%). There were 204 unique presenters; 25% presented at subsequent meetings. Of these unique presenters, 46% published their research and 31% published additional research after residency. Among presenters who completed residency or fellowship (N = 119), 34% practiced in a university setting, and 61% practiced in a community setting; 31% practiced in Wisconsin. When comparing clinical vs basic science presenters, there was no difference in fellowship completion (37% vs 44%; p = 0.190) or practice type (38% vs 46% in a university setting; p = 0.397). Repeat presenters were more likely to pursue a fellowship vs those presenting once (76% vs 37%; p = 0.001). Research presentations by surgical trainees at an ACS state chapter meeting frequently led to peer-reviewed publications. Presenters were likely to pursue research opportunities after residency. Repeat presenters were more likely to pursue a fellowship. ACS Wisconsin chapter meetings provide an

    An important part of the workshop was a series of invited presentations. The presentations were intended to both provide the participants with an understanding of various organisational approaches and activities as well as to stimulate the exchange of ideas during the small group discussion sessions. The presentation subjects ranged from current organisational regulations and licensee activities to new organisational research and the benefits of viewing organisations from a different perspective. There were more than a dozen invited presentations. The initial set of presentations gave the participants an overview of the background, structure, and aims of the workshop. This included a short presentation on the results from the regulatory responses to the pre-workshop survey. Representatives from four countries (Sweden, Canada, Finland, and the United Kingdom) expanded upon their survey responses with detailed presentations on both regulatory and licensee safety-related organisational activities in their countries. There were also presentations on new research concerning how to evaluate safety critical organisations and on a resilience engineering perspective to safety critical organisations.

    . However, EGCG potently inhibited sphere formation and can eliminate the stem cell characteristics of NPC and inhibit the epithelial-mesenchymal transition (EMT signatures. Conclusions Overall, these findings show that NPC cells with sphere formations possess the properties of CSC. Using this model, we found that EGCG regulated NPC CSC, their self-renewal capacity, and inhibited their invasive characteristics. It supports the pivotal role of EGCG as a dietary compound targeting NPC and may decrease recurrence and metastasis in nasopharyngeal carcinoma cells.

    Full Text Available Integrative veterinary medicine, the combination of complementary and alternative therapies with conventional care, is increasingly prevalent in veterinary practice and a focus of clinical instruction in many academic teaching institutions. However, the presenting complaints, therapeutic modalities, and patient population in an integrative medicine service have not been described. A retrospective analysis of 5,195 integrative patient treatment sessions in a veterinary academic teaching hospital demonstrated that patients most commonly received a combination of therapeutic modalities (39% of all treatment sessions. The 274 patients receiving multiple modalities were most frequently treated for neurologic and orthopedic disease (50.7% versus 49.6% of all presenting complaints, resp.. Older neutered or spayed dogs (mean age = 9.0 years and Dachshunds were treated more often than expected based on general population statistics. Acupuncture, laser therapy, electroacupuncture, and hydrotherapy were frequently administered (>50% patients. Neurologic patients were more likely to receive acupuncture, electroacupuncture, and therapeutic exercises but less likely than orthopedic patients to receive laser, hydrotherapy, or therapeutic ultrasound treatments (P<0.05. The results suggest that the application of these specific modalities to orthopedic and neurologic diseases should be subjected to increased evidence-based investigations. A review of current knowledge in core areas is presented.

    The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

    Full Text Available Abstract Objective To determine journal publication rates of scientific papers presented orally at the European Congress of Radiology (ECR 2010, with comparison of country data to ECR 2000. Methods All oral presentations from ECR 2010 were evaluated for publication between 2010 and 2014 using the MEDLINE database. Countries, collaborations, subspecialties, modalities and study design were ranked by publication percentage. Chi-square tests were used to compare publication percentages for each category of variables. Hazard ratios (HR were calculated for each country relative to the host nation, Austria. ECR 2010 country statistics were compared with analogous data from ECR 2000. Results In total, 360/840 abstracts were subsequently published (43 %. The author’s country of origin (p = 0.02, subspecialty (p = 0.02 and study design (p = 0.001 were significantly associated with subsequent publication. Switzerland, the Netherlands, France and Germany were among the top six countries by publication percentage in 2000 and 2010. In 2010, Switzerland had the highest publication rate (62 % and HR in comparison to Austria (HR 2.62 [1.31–5.25], p = 0.01. Three Asian nations increased relative publication rates over the 10-year period. Conclusion Several European nations consistently convert relatively high percentages of oral abstracts at ECR into publications, and the influence of Asian countries is increasing. Main Messages • Certain European nations consistently publish high percentages of orally presented abstracts at ECR. • The influence of several Asian countries on ECR is increasing. • Country, subspecialty and study design are significantly associated with journal publication. • Authors collaborating internationally have the highest publication rates and mean impact factors. • Among all modalities, PET-CT, MRI and CT have the highest publication percentages.

Our investigation will assess these differences in addition to known therapeutic, patient, and histopathologic factors.MethodsA retrospective review of the Surveillance Epidemiology and End Reporting database was conducted through the years 2007–2012. The population was split into nine different ethnic groups. Population differences were assessed via chi-square testing. Multivariable analysis (MVA were used to detect overall survival (OS differences in the total surgical population (TS, N = 35,689 in an ear (T1–T2 < 4 cm N0 surgical population [early-stage resectable (ESR, N = 17,931]. Lung cancer-specific survival (LCSS was assessed in the ESR.ResultsIn the TS population, as compared to Whites, Blacks, and Hispanics presented with younger age, more adenocarcinomas, lower rates of marriage, lower rates of insurance, less stage I tumors, and had less nodes examined, but their type of surgical procedures and OS/LCSS were the same. MVA demonstrated that lower OS and LCSS were associated with males, single/divorced/widowed partnership, lower income (TS only, and Medicaid insurance. MVA also found that Blacks and Hispanics had a similar OS/LCSS to Whites and that all ethnic groups were associated with a similar or better outcomes. The 90-day mortality and positive nodes were correlated with not having insurance and not being married, but they were not associated with ethnicity.ConclusionIn TS and ESR groups, OS was not different in the two largest ethnic groups (Black and Hispanic as compared to Whites, but was related to single/widowed/divorced status, Medicaid insurance, and income (TS group only. Nodal positivity was associated with patients who did not have a married partner or insurance suggesting that these factors may impact disease

    Full Text Available Abstract Introduction Pituicytoma is a rare neoplasm of the neurohypophysis. To the best of our knowledge there have been no reports of pituicytoma in which long-term magnetic resonance imaging observation was performed. We calculated the doubling time of the tumor volume and described the growth pattern of a pituicytoma. Case presentation A 52-year-old Japanese man with a history of decreased libido was found to have a sellar and suprasellar mass. He underwent transsphenoidal surgery, but only a small specimen was obtained because of intraoperative bleeding. The tentative histological diagnosis was schwannoma. He noticed bitemporal hemianopsia 7 years later. A follow-up magnetic resonance imaging disclosed a tumor volume doubling time of 3830 days. Transcranial gross-total tumor resection was performed. The lesion consisted of elongated and plump tumor cells that were arranged in a fascicular or storiform pattern and were positive for S-100 protein and focally positive for glial fibrillary acidic protein. The final histological diagnosis was pituicytoma. Conclusion Pituicytoma is a slow-growing tumor, but the growth rate may change during follow-up.

    Despite attention to the sexual behaviors of non-gay-identified (NGI) men who have same-sex encounters, virtually no research has focused on issues of partner desirability and selection. Limited evidence suggests that a subgroup of men who have sex with men (MSM) advertise online for sexual encounters with NGI men. Exchange theory provided a framework to investigate this seeking of NGI men, based on the content of Internet personal advertisements for same-sex encounters. Researchers analyzed 282 ads posted to an online bulletin board. Ads by men who explicitly desired encounters with NGI men were compared with those by men who did not indicate this preference in potential partners. Multivariate analyses revealed that NGI-seeking men had significantly increased odds of identifying as discreet (Adjusted odds ratio [AOR] = 2.82), seeking a discreet encounter (AOR = 4.68), seeking a masculine partner (AOR = 2.18), being willing to host (AOR = 2.77), as well as seeking oral-receptive sex (AOR = 2.69), unprotected oral sex (AOR = 6.76), and anal-receptive sex (AOR = 2.18). Further, NGI-seeking ads were more likely to not mention condom use or safer sex practices (AOR = 4.13) and were less likely to indicate a desire for oral-insertive sex (AOR = 0.34) and rimming (AOR = 0.21). Findings suggest that some men may deliberately present themselves in ways that they perceive as being attractive to NGI men, and have research implications for NGI MSM, their partners, and the risk outcomes of these online ads.

    Identifying variables that influence presenting visual acuity (VA) in patients with neovascular age-related macular degeneration (nAMD) is important because it is a strong predictor of long-term outcomes. To assess the clinical and social characteristics associated with low presenting VA in nAMD patients. The present study is a cross-sectional analysis from a prospective, observational database. We identified 3242 treatment-naïve patients from 54 Australian practices in the Fight Retinal Blindness! registry. Age, gender, ethnicity and VA were recorded at the baseline visit. Socio-economic status was determined using the Australian Bureau of Statistics socio-economic indexes for areas. Association between clinical and socio-economic characteristics with presenting VA was identified. Poor VA (≤35 letters) in the presenting eye was associated with older age (adjusted odds ratio [AOR]: 1.33 for patients aged ≥80 years vs. <80 years [95% confidence interval, CI: 1.04, 1.71]), treatment at a public practice (AOR: 1.91 for public vs. private practices [95% CI: 1.46, 2.50]) and intermediate (36-69 letters) VA in the fellow eye (AOR: 0.67 [95% CI: 0.47, 0.95] and 0.64 [95% CI: 0.48, 0.85] for poor [≤35 letters] and good [≥70 letters] VA vs. intermediate VA in the fellow eye). Gender, ethnicity and socio-economic status were not independently associated with VA at presentation. Poor presenting vision is detrimental to the long-term outcomes of nAMD. Poor presentation of nAMD in Australia may not be related to socio-economic circumstances, but due to systems of care. Further research is warranted to determine why patients at public practices present with worse vision compared with private practices in Australia. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

    μThis study of phosphorus (P) cycling in eutrophic Upper Klamath Lake (UKL), Oregon, was conducted by the U.S. Geological Survey in cooperation with the U.S. Bureau of Reclamation. Lakebed sediments from the upper 30 centimeters (cm) of cores collected from 26 sites were characterized. Cores were sampled at 0.5, 1.5, 2.5, 3.5, 4.5, 10, 15, 20, 25, and 30 cm. Prior to freezing, water content and sediment pH were determined. After being freeze-dried, all samples were separated into greater than 63-micron (μm) particle-size (coarse) and less than 63-μm particle-size (fine) fractions. In the surface samples (0.5 to 4.5 cm below the sediment water interface), approximately three-fourths of the particles were larger than 63-μm. The ratios of the coarse particle-size fraction (>63 μm) and the fine particle-size fraction (determination of total concentrations of aluminum (Al), calcium (Ca), carbon (C), iron (Fe), poorly crystalline Fe, nitrogen (N), P, and titanium (Ti). Total Fe concentrations were the largest in sediment from the northern portion of UKL, Howard Bay, and the southern portion of the lake. Concentrations of total Al, Ca, and Ti were largest in sediment from the northern, central, and southernmost portions of the lake and in sediment from Howard Bay. Concentrations of total C and N were largest in sediment from the embayments and in sediment from the northern arm and southern portion of the lake in the general region of Buck Island. Concentrations of total C were larger in the greater than 63-μm particle-size fraction than in the less than 63-μm particle-size fraction. Sediments were sequentially extracted to determine concentrations of inorganic forms of P, including loosely sorbed P, P associated with poorly crystalline Fe oxides, and P associated with mineral phases. The difference between the concentration of total P and sum of the concentrations of inorganic forms of P is referred to as residual P. Residual P was the largest fraction of P in all

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

IN a data sample of 55 x 10{sup 6} B{bar B} events they measure a branching fraction of {Beta}(B {yields} {rho}{ell}{nu}) = (3.39 {+-} 0.44{sub stat} {+-} 0.52{sub sys} {+-} 0.60{sub th}) x 10{sup -4} yielding |V{sub ub}| = (3.69 {+-} 0.23{sub stat} {+-} 0.27{sub sys -0.59th}{sup +0.40}) x 10{sup -3}. Next, they report on a preliminary study of the radiative penguin modes B {yields} K{ell}{sup +}{ell}{sup -} and B {yields} K*{ell}{sup +}{ell}{sup -}. In a data sample of 84 x 10{sup 6} B{bar B} events they observe a significant signal (4.4{sigma}) in B {yields} K{ell}{sup +}{ell}{sup -}, yielding a branching fraction of {Beta}(B {yields} K{ell}{sup +}{ell}{sup -}) = (0.78{sub -0.20-0.18}{sup +0.24+0.11}) x 10{sup -6}. In B {yields} K*{ell}{sup +}{ell}{sup -} the observed yield is not yet significant (2.8{sigma}), yielding an upper limit of the branching fraction of {Beta}(B {yields} K*{ell}{sup +}{ell}{sup -}) 3.0 x 10{sup -6} {at} 90% confidence level. Finally, they summarize preliminary results of searches for B {yields} {rho}({omega}){gamma}, B{sup +} {yields} K{sup +} {nu}{bar {nu}} and B{sup 0} {yields} {ell}{sup +}{ell}{sup -}.

    commercial perspective "is that with the establishment of export quotas, the two countries incurred in trade losses. In "The use of competitive intelligence in the selection of export markets - a comparative analysis of four methods", Moema Pereira Nunes and Laura de Souza Lequain address one of the biggest challenges facing companies that want to export their products: How to choose an import market . Through rigorous analysis of the characteristics of four methods commonly used to perform this choice, they come to the conclusion that all of them are difficult to apply for  small and medium enterprises. While that result may be frustrating  for readers that would like to find in the paper an answer to the problem of export market selection by SMEs, the article has the great merit of drawing attention to the necessity to work in this direction. Not to mention that it serves as an advanced introduction to the knowledge of methods of analysis of import markets. In "Influences of international experience and business diversification on the degree of internationalization of Brazilian multinationals" Ivano Ribeiro, Fernando Antonio Ribeiro Serra, and Geysler Rogis Flor Bertolini analyze the impacts of two dimensions - the time of international experience and the diversification of business - on the degree of internationalization of Brazilian multinationals. Through regression analysis, they find indications that the company's business diversification is positively related to the degree of internationalization. Contrary, however, to what one would expect from established theories of internationalization of business, they find that prior international experience of Brazilian firms does not seem to predict the degree of internationalization. The authors suggest that this result may be related to the fact that the internationalization process of Brazilian multinationals is still a relatively recent phenomena.

    Primary hyperaldosteronism (Conns' syndrome) commonly presents with a combination of clinical features of hypokalemia and hypertension. Atypical presentations like normotension, normokalemia and neurological ailments are described in few cases. We encountered two such cases, the first presenting with acute neurological complaint and second case having insignificant hypertension. Both the patients had a characteristic biochemical and imaging profile consistent with primary hyperaldosteronism and responded to surgical resection of adrenal adenoma. (author)

    We study a complex action theory (CAT) whose path runs over not only past but also future. We show that, if we regard a matrix element defined in terms of the future state at time T and the past state at time TA as an expectation value in the CAT, then we are allowed to have the Heisenberg equation......, Ehrenfest's theorem, and the conserved probability current density. In addition,we showthat the expectation value at the present time t of a future-included theory for large T - t and large t - T corresponds to that of a future-not-included theory with a proper inner product for large t - T. Hence, the CAT...

    Full Text Available O presente trabalho buscou avaliar a influência do retorno do lodo produzido em filtros biológicos percoladores (FBP sobre as características da biomassa em reatores UASB utilizados para o tratamento de esgoto sanitário. Os experimentos foram conduzidos em reatores em escala piloto e em escala de demonstração, sendo que os reatores UASB foram operados com e sem retorno do lodo produzido nos FBP. Os resultados obtidos indicaram uma diminuição no diâmetro das partículas de lodo, durante as fases com retorno de lodo, mas apenas para as amostras de lodo tomadas nos pontos mais altos dos reatores anaeróbios. A estabilidade e a atividade metanogênica específica do lodo anaeróbio praticamente não se modificaram com o retorno de lodo. Conforme esperado, a produção específica de lodo anaeróbio aumentou com o retorno de lodo.This work aimed at evaluating the influence of the return of excess aerobic sludge produced in trickling filters (TF upon the biomass characteristics in UASB reactors used for the treatment of domestic sewage. The experiments were carried out in pilot and demonstration-scale reactors, with the UASB reactors being operated with and without the return of sludge produced in the TF. Smaller sludge particle sizes were observed when the aerobic sludge was returned to the UASB reactor, but only for sludge samples collected in the upper parts of the anaerobic reactors. Sludge stability and specific methanogenic activity were not affected by the return of sludge. As expected, the specific anaerobic sludge production increased with the return of sludge.

    Coordinating additives are included in porphyrinoid-based materials to promote intermolecular organization and improve one or more photoelectric characteristics of the materials. The coordinating additives are selected from fullerene compounds and organic compounds having free electron pairs. Combinations of different coordinating additives can be used to tailor the characteristic properties of such porphyrinoid-based materials, including porphyrin oligomers. Bidentate ligands are one type of coordinating additive that can form coordination bonds with a central metal ion of two different porphyrinoid compounds to promote porphyrinoid alignment and/or pi-stacking. The coordinating additives can shift the absorption spectrum of a photoactive material toward higher wavelengths, increase the external quantum efficiency of the material, or both.

    To describe the clinical characteristics, staging and presentation of patients with familial exudative vitreoretinopathy (FEVR) in our clinical practice over the last 25 years. Case series, retrospective review. We included 273 eyes of 145 patients. Data collected from charts included gender, gestational age at birth, birthweight, age at presentation, referring diagnosis, family history, prior ocular surgery, and clinical presentation in each eye. Eyes with invasive posterior segment procedures before initial presentation were excluded. Demographics on presentation and clinical staging. Patients were slightly male predominant (57%) with a mean birthweight of 2.80 kg (range, 740 g-4.76 kg), mean gestational age of 37.8 weeks (range, 25-42), and mean age at presentation of almost 6 years (range, presentation, gestational age, and birthweight. Although a positive family history on presentation may support the diagnosis of FEVR, a negative family history is of little help. The majority of retinal folds extended radially in the temporal quadrants, but radial folds were seen in almost all quadrants. Fellow eyes demonstrated a wide variation in symmetry. The presentation of FEVR may mimic the presentation of other pediatric and adult vitreoretinal disorders, and careful examination is often crucial in making the diagnosis of FEVR.

    HIV-2 is endemic in West Africa. There is a lack of evidence-based guidelines on the diagnosis, management and antiretroviral therapy (ART) for HIV-2 or HIV-1/HIV-2 dual infections. Because of these issues, we designed a West African collaborative cohort for HIV-2 infection within the framework of the International epidemiological Databases to Evaluate AIDS (IeDEA). We collected data on all HIV-2 and HIV-1/HIV-2 dually seropositive patients (both ARV-naive and starting ART) and followed-up in clinical centres in the IeDEA-WA network including a total of 13 clinics in five countries: Benin, Burkina-Faso Côte d'Ivoire, Mali, and Senegal, in the West Africa region. Data was merged for 1,754 patients (56% female), including 1,021 HIV-2 infected patients (551 on ART) and 733 dually seropositive for both HIV-1 and HIV 2 (463 on ART). At ART initiation, the median age of HIV-2 patients was 45.3 years, IQR: (38.3-51.7) and 42.4 years, IQR (37.0-47.3) for dually seropositive patients (p = 0.048). Overall, 16.7% of HIV-2 patients on ART had an advanced clinical stage (WHO IV or CDC-C). The median CD4 count at the ART initiation is 166 cells/mm(3), IQR (83-247) among HIV-2 infected patients and 146 cells/mm(3), IQR (55-249) among dually seropositive patients. Overall, in ART-treated patients, the CD4 count increased 126 cells/mm(3) after 24 months on ART for HIV-2 patients and 169 cells/mm(3) for dually seropositive patients. Of 551 HIV-2 patients on ART, 5.8% died and 10.2% were lost to follow-up during the median time on ART of 2.4 years, IQR (0.7-4.3). This large multi-country study of HIV-2 and HIV-1/HIV-2 dual infection in West Africa suggests that routine clinical care is less than optimal and that management and treatment of HIV-2 could be further informed by ongoing studies and randomized clinical trials in this population.

  10. Neoclassical transport including collisional nonlinearity.

    Candy, J; Belli, E A

    2011-06-10

    In the standard δf theory of neoclassical transport, the zeroth-order (Maxwellian) solution is obtained analytically via the solution of a nonlinear equation. The first-order correction δf is subsequently computed as the solution of a linear, inhomogeneous equation that includes the linearized Fokker-Planck collision operator. This equation admits analytic solutions only in extreme asymptotic limits (banana, plateau, Pfirsch-Schlüter), and so must be solved numerically for realistic plasma parameters. Recently, numerical codes have appeared which attempt to compute the total distribution f more accurately than in the standard ordering by retaining some nonlinear terms related to finite-orbit width, while simultaneously reusing some form of the linearized collision operator. In this work we show that higher-order corrections to the distribution function may be unphysical if collisional nonlinearities are ignored.

    We herein describe a second Japanese case of sarcoidosis presenting Addison's disease. A 52-year-old man was diagnosed with sarcoidosis based on clinical and laboratory findings, including bilateral hilar lymphadenopathy and elevated levels of serum angiotensin-converting enzyme and lysozyme, as well as the presence of noncaseating epithelioid granulomas. The patient also exhibited general fatigue, pigmentation, weight loss, hypotension and hyponatremia, suggestive of chronic adrenocortical insufficiency. An endocrine examination confirmed primary adrenocortical insufficiency. This case suggests the direct involvement of sarcoid granuloma in the adrenal glands.

    1986-01-01

    The present edition has been completely updated and revised, reflecting the very great changes which have come about in the oil industry over the last 18 years, since the last edition appeared. The expressed aim of the Handbook is to combine explanations of the processes of today's petroleum industry, from crude oil exploration to product end-use, with some historical background and explanation of the economic context in which the oil, gas and petrochemical industries operate. It is therefore intended as a technical reference manual, although it will be of interest both to specialists in search of information outside their expertise and to the more general reader. Chapter 3, entitled Exploration and Production, is concerned with structural geology, exploration methods and theory, and reservoir engineering, although the economic and financial aspects of drilling, project management and communication logistics are also considered. Other chapters are devoted to the distribution, consumption and end use of natural gas and NGL, the chemistry of petroleum, the manufacture of oil products, marketing, supply and trading, petrochemicals, synfuels, R and D, environmental conservation, and introduction to the world petroleum industry, and a review of oil and gas in the centrally planned economies, although only the Soviet Union is considered in any detail.

    Volvulus of the splenic flexure is very rare cause of colonic obstruction constituting 2% of cases of colonic segmental volvulus. Primary splenic flexure volvulus (SFV) is due to congenital absence or laxity of the phrenocolic, gastro colic, and splenocolic ligaments while secondary volvulus is due to other causes including some prior surgery releasing these ligaments. A preoperative diagnosis can be established based on the characteristic radiological findings on plain x-ray abdomen and CT scan. We present a case of SFV in a young man who presented with acute abdominal pain, and distension, and illustrate the usefulness of CT scan, and plain x-ray of the abdomen in making a preoperative diagnosis. Laparotomy revealed a gangrenous SFV, which was resected and primary anastomosis was carried out. Literature is reviewed with regards to predisposing factors, presentation, investigation, and management among the more than 32 cases reported so far. (author)

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

  20. Characteristics of healthcare wastes

    A comprehensive understanding of the quantities and characteristics of the material that needs to be managed is one of the most basic steps in the development of a plan for solid waste management. In this case, the material under consideration is the solid waste generated in healthcare facilities, also known as healthcare waste. Unfortunately, limited reliable information is available in the open literature on the quantities and characteristics of the various types of wastes that are generated in healthcare facilities. Thus, sound management of these wastes, particularly in developing countries, often is problematic. This article provides information on the quantities and properties of healthcare wastes in various types of facilities located in developing countries, as well as in some industrialized countries. Most of the information has been obtained from the open literature, although some information has been collected by the authors and from reports available to the authors. Only data collected within approximately the last 15 years and using prescribed methodologies are presented. The range of hospital waste generation (both infectious and mixed solid waste fractions) varies from 0.016 to 3.23 kg/bed-day. The relatively wide variation is due to the fact that some of the facilities surveyed in Ulaanbaatar include out-patient services and district health clinics; these facilities essentially provide very basic services and thus the quantities of waste generated are relatively small. On the other hand, the reported amount of infectious (clinical, yellow bag) waste varied from 0.01 to 0.65 kg/bed-day. The characteristics of the components of healthcare wastes, such as the bulk density and the calorific value, have substantial variability. This literature review and the associated attempt at a comparative analysis point to the need for worldwide consensus on the terms and characteristics that describe wastes from healthcare facilities. Such a consensus would greatly

    This document is a response to the Photovoltaic Research, Development, and Demonstration Act of 1978 (P.L. 95-590) which required the generation of performance criteria for photovoltaic energy systems. Since the document is evolutionary and will be updated, the term interim is used. More than 50 experts in the photovoltaic field have contributed in the writing and review of the 179 performance criteria listed in this document. The performance criteria address characteristics of present-day photovoltaic systems that are of interest to manufacturers, government agencies, purchasers, and all others interested in various aspects of photovoltaic system performance and safety. The performance criteria apply to the system as a whole and to its possible subsystems: array, power conditioning, monitor and control, storage, cabling, and power distribution. They are further categorized according to the following performance attributes: electrical, thermal, mechanical/structural, safety, durability/reliability, installation/operation/maintenance, and building/site. Each criterion contains a statement of expected performance (nonprescriptive), a method of evaluation, and a commentary with further information or justification. Over 50 references for background information are also given. A glossary with definitions relevant to photovoltaic systems and a section on test methods are presented in the appendices. Twenty test methods are included to measure performance characteristics of the subsystem elements. These test methods and other parts of the document will be expanded or revised as future experience and needs dictate.

    2007-01-01

    Medical practice leadership teams, often consisting primarily of physicians with limited financial backgrounds, must make important business decisions and continuously monitor practice operations. In order to competently perform this duty, they need financial reports that are relevant and easy to understand. This article explores financial reporting and decision-making in a physician practice. It discusses reports and tools, such as ratios, graphs, and comparisons, that practices typically include in their reports. Because profitability and cash flow are often the most important financial considerations for physician practices, reports should generally focus on the impact of various activities and potential decisions upon these concerns. This article also provides communication tips for both those presenting practice financial information and those making the decisions. By communicating effectively, these leaders can best use financial information to improve decision-making and maximize financial performance.

    1995-08-01

    To properly take climate change into account in the analysis of energy investment decisions, it is required to apply decision analysis methods that are capable of considering the specific characteristics of climate change (large uncertainties, long term horizon). Such decision analysis methods do exist. They can explicitly include evolving uncertainties, multi-stage decisions, cumulative effects and risk averse attitudes. Various methods are considered in this report and two of these methods have been selected: hedging calculations and sensitivity analysis. These methods are applied to illustrative examples, and its limitations are discussed. The examples are (1a) space heating and hot water for new houses from a private investor perspective and (1b) as example (1a) but from a government perspective, (2) electricity production with an integrated coal gasification combined cycle (ICGCC) with or without CO 2 removal, and (3) national energy strategy to hedge for climate change. 9 figs., 21 tabs., 42 refs., 1 appendix

    2015-05-13

    Crohn's disease is a chronic inflammatory bowel condition that affects more than 115,000 people in the UK. This article focuses on Crohn's disease in adolescents. Management of the condition in this group should address adolescent-specific characteristics and treatment goals. Key elements include optimising growth, pubertal development and social functioning, including education. The condition can affect an individual's mental and emotional wellbeing significantly, as well as their physical health. As adolescence is a time of great change, the additional burden of a chronic illness can prove difficult to manage. The authors provide information on the presentation of Crohn's disease in adolescence and insights into the particular issues encountered by this group.

    The Department of Energy is supporting a number of programs directed at improving nuclear power's ability to compete by the mid 1990s in providing some of what will be urgently needed new baseload capacity, and at meeting both utility requirements and public goals. More specifically, we are co-funding demonstration by 1993 of the process for life extension of current nuclear plants. We are supporting the development of new ALWR designs which rely more on methods such as natural circulation, gravity, reduced power density, or the characteristics of materials, rather than engineered systems to provide safety. These designs will meet the criteria set forth in EPRI's Utility Requirements Documents. We have established a cost-sharing program to demonstrate the success of the nuclear plant standardization and licensing process by obtaining NRC certification by 1992 or 1993 of two evolutionary 1300MWe ALWR designs. We are also cost-sharing a program to certify by 1995 passively safe 600MWe ALWRs employing more natural safety features and modular construction. These programs will involve a rule-making hearing process. We are supporting the development and possible certification early in the next century of modular high temperature gas reactor and advanced liquid metal reactor plant designs. We are planning to demonstrate the early site approval licensing process through a cost-sharing arrangement with the private sector by 1995. In developing the National Energy Strategy, we are examining the issue of a fully satisfactory regulatory process, including the possibility of legislation codifying 10 CFR Part 52, limiting the possible delays associated with a potential second hearing and dealing with emergency planning issues before start of construction. We recently announced a restructured plan to develop a permanent waste repository by 2010. By 1995 we expect to have made significant progress in evaluating the suitability of Yucca Mountain. We expect to have selected a

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

    2012-02-01

    Subacute cutaneous lupus erythematosus (SCLE) is a recognised variant of lupus erythematosus (LE), which accounts for 10-15% of all cases of cutaneous LE, occurring most commonly in young to middle-aged white women. Diagnosis is based on the detection of anti-Ro\\/SS-A antibodies in the skin and serum, characteristic clinical and histological cutaneous involvement, and relatively mild systemic involvement. Several unusual variants of SCLE have been reported including erythrodermic SCLE, SCLE with vitiligo-like lesions, acral SCLE and bullous SCLE. Poikoilodermatous SCLE is a recognised but rare variant of SCLE. There are currently only two case reports, comprising five individual cases, in the literature. We present a case of SCLE in which the main clinical findings were an extensive photodistributed poikilodermatous rash and alopecia.

    structure (chemical order, anisotropy, charge transfer, magnetic order) versus an external parameter like temperature, pressure, magnetic or electric field. Modern crystallography is also extended to the study of very small crystals, powders, ill-ordered or non-crystallized materials. Thus presently, crystallography is concerned with any solid that “scatters” an incident beam. Nevertheless, as quoted by A. Guinier, “the problems facing crystallographers have only changed, ... new ones have appeared which require reflection and imagination, ... and which in turn may still bring much joy to all those who like crystallography” [4]. Such developments open up crystallography to modern materials like artificial ones and nanostructures with low- and/or multi-scaled-periodicities and/or extremely small “crystal size” and to materials of the “real world”, with mixtures of phases and/or amorphous contribution and/or defects, a common characteristic of ancient materials analysed in patrimonial research. In our contribution we will show by selected examples that these improvements were allowed (i) by the use of powerful sources, apparatus and detectors which allow micro-diffraction, in-situ diffraction, spectroscopy, resonant scattering, inelastic scattering, coherent scattering, (ii) by the development of methods like diffraction anomalous fine structure (DAFS), pair distribution function (PDF), simulated annealing, single object reconstruction, (iii) by combination of scattering and spectroscopy and by combination of scattering and microscopy. Such combination of different approaches is very efficient and, as said by H. Curien at the IUCr Bordeaux Congress in 1990, “in crystallography, there is a constant alternation between the crystal space and its associated reciprocal space, ... the alternation between experiment and model building is another feature of crystallography activity ..., the crystallographer relies both on his computer and on his diffractometer

Nurses are increasingly being asked to present in formal and informal situations, such as conferences, poster presentations, job interviews, case reports and ward-based teaching. This article explores the principles underpinning the development of these skills, discusses the situations in which they could be applied and demonstrates how nurses might improve and develop as presenters.

  20. Numerical optimization of conical flow waveriders including detailed viscous effects

    Science.gov (United States)

    Bowcutt, Kevin G.; Anderson, John D., Jr.; Capriotti, Diego

    1987-01-01

    A family of optimized hypersonic waveriders is generated and studied wherein detailed viscous effects are included within the optimization process itself. This is in contrast to previous optimized waverider work, wherein purely inviscid flow is used to obtain the waverider shapes. For the present waveriders, the undersurface is a streamsurface of an inviscid conical flowfield, the upper surface is a streamsurface of the inviscid flow over a tapered cylinder (calculated by the axisymmetric method of characteristics), and the viscous effects are treated by integral solutions of the boundary layer equations. Transition from laminar to turbulent flow is included within the viscous calculations. The optimization is carried out using a nonlinear simplex method. The resulting family of viscous hypersonic waveriders yields predicted high values of lift/drag, high enough to break the L/D barrier based on experience with other hypersonic configurations. Moreover, the numerical optimization process for the viscous waveriders results in distinctly different shapes compared to previous work with inviscid-designed waveriders. Also, the fine details of the viscous solution, such as how the shear stress is distributed over the surface, and the location of transition, are crucial to the details of the resulting waverider geometry. Finally, the moment coefficient variations and heat transfer distributions associated with the viscous optimized waveriders are studied.

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%.

    The numerical simulation of aerosol transport, including the effects of chemical and nuclear reactions presents a challenging dynamic accounting problem. Particles of different sizes agglomerate and settle out due to various mechanisms, such as diffusion, diffusiophoresis, thermophoresis, gravitational settling, turbulent acceleration, and centrifugal acceleration. Particles also change size, due to the condensation and evaporation of materials on the particle. Heterogeneous chemical reactions occur at the interface between a particle and the suspending medium, or a surface and the gas in the aerosol. Homogeneous chemical reactions occur within the aersol suspending medium, within a particle, and on a surface. These reactions may include a phase change. Nuclear reactions occur in all locations. These spontaneous transmutations from one element form to another occur at greatly varying rates and may result in phase or chemical changes which complicate the accounting process. This paper presents an approach for inclusion of these effects on the transport of aerosols. The accounting system is very complex and results in a large set of stiff ordinary differential equations (ODEs). The techniques for numerical solution of these ODEs require special attention to achieve their solution in an efficient and affordable manner. 4 refs

    Introduction: systemic sclerosis is an autoimmune disease characterized by endothelial damage, and skin, vessel and internal organ fibrosis and inflammation. There are differences in terms of frequency, severity and prognosis for the different ethnic groups, what reinforces the importance of the study in each geographical region with the purpose of enabling early diagnosis of its incipient symptoms.Methods: we conducted a descriptive and retrospective study form March 2006 through March 2008, including patients with a final diagnosis of systemic sclerosis, who are treated at the Systemic Autoimmune Diseases Unit at the Clinicas Hospital. Results: 31 women were included in the study, average follow-up of patients was 39.2 months, and average age at the time of diagnosis was 47.6 years. Eleven patients (35,5) presented diffuse disease and 20 (64.5) of them evidenced limited disease. Thirty patients presented Raynaud's phenomenon. In 92 of cases capilaroscopy showed a sclerodermiform pattern. In terms of the respiratory system, we found interstitial pathology in 25 of cases, pulmonary arterial hypertension in 22.2 and are restrictive pattern in respiratory function studies in 35.5. Also, 67.7 presented digestive manifestations and 9.6 developed sclerodermic renal crisis. We found anti-nuclear antibodies (ANA) in 29 out of 31 patients (93,5) patients; 16 presented anticentromere antibodies and five anti-topoisomerasa-I antibodies. The four patients (12.9)who died during follow-up presented common elements such as diffuse sclerosis, digital ulcers and severe respiratory compromise. Conclusions: the clinical and immune characteristics found in our study were similar to those described in other series. Should there be no specific treatment, it is essential to perform regular assessment of visceral impact in order to control and delay complications which result in high morbimortality rates.

    Nurses are full partners with other health care professionals. Until fairly recently the scope of nurses potential in entrepreneurship has not been widely recognized. The present study tries to evaluate entrepreneurship psychological characteristics among nurses. The survey instrument included scales measuring entrepreneurship psychological characteristics including locus of control, need for achievement, risk taking propensity, ambiguity tolerance, and innovation, among nurses in the Shahid Sadoughi Hospital, Yazd, Iran in 2013. In this study average of entrepreneurship psychological characteristics of nurses which are higher than standard mark. The majority of the nurses have average entrepreneurship (20.4%). It means that they have some strong entrepreneurship. The result show that average of the need for achievement is 34.5%, the locus of control 33.8%, risk taking propensity 33.2%, ambiguity tolerance 34.2%, and innovation 41.6%. The results indicate that the 4 dimensions of the need for achievement, risk taking, Ambiguity Tolerance, and Innovation were significant. However, the locus of control is not significant at a 0.05 significance level. In terms, entrepreneurially nurses are comparatively more innovative, have risk taking attitudes, need for achievement, Ambiguity Tolerance, and Innovation. Results largely support significant positive relationships between psychological traits and entrepreneurial orientations.

    Medical and nutritional treatment for renal disease, now a major public health issue, is highly complicated. Nutritional therapy must seek to retard renal dysfunction, maintain an optimal nutritional status and prevent the development of underlying pathologies. To analyze ten fish species to identify those that, because of their low phosphorus content, high biological value protein and elevated n-3 fatty acids EPA and DHA, could be included in renal patient's diet. The following fish species (Litte tunny, Red drum, Spotted eagleray, Escolar, Swordfish, Big-scale pomfret, Cortez flounder, Largemouth blackbass, Periche mojarra, Florida Pompano) were analyzed according to the AOAC and Keller techniques to determine their protein, phosphorus, sodium, potassium, cholesterol, vitamins D(3) and E, and n-3 EPA+DHA content. These results were used to calculate relations between nutrients. The protein in the analyzed species ranged from 16.5 g/100 g of fillet (Largemouth black bass) to 27.2 g/100 g (Red drum); the lowest phosphorus value was 28.6 mg/100 g (Periche mojarra) and the highest 216.3 mg/100 g (Spotted eagle ray). 80% of the fish presented > 100 mg EPA + DHA in 100 g of fillet. By its Phosphorus/gProtein ratio, Escolar and Swordfish could not be included in the renal diet; Little tunny, Escolar, Big-scale pomfret, Largemouth black-bass, Periche mojarra and Florida Pompano presented a lower Phosphorus/EPA + DHA ratio. Florida pompano is the most recommended specie for renal patients, due to its optimal nutrient relations. However, all analyzed species, except Escolar and Swordfish, could be included in renal diets.

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

  16. Isolated Torticollis May Present as an Atypical Presentation of Meningitis

    Directory of Open Access Journals (Sweden)

    Roger Chirurgi

    2012-01-01

    Full Text Available Background. Bacterial meningitis is a life-threatening medical emergency that requires urgent diagnosis and treatment. Diagnosis is infrequently missed if the patient presents with the classic symptoms of fever, headache, rash, nuchal rigidity, or Kernig or Brudzinski sign. However, it may be less obvious in neonates, elderly, or immunocompromised patients. Meningitis which presents as isolated torticollis, without any other signs or symptoms, is exceedingly rare. Objective. To identify an abnormal presentation of meningitis in an adult immunocompromised patient. Case Report. We present a case of an adult diabetic male who presented multiple times to the ED with complaint of isolated torticollis, who ultimately was diagnosed with bacterial meningitis. Conclusion. We propose that in the absence of sufficient explanation for acute painful torticollis in an immunocompromised adult patient, further evaluation, possibly including a lumbar puncture may be warranted.

Figure 1 illustrates the modular nature of the lab curriculum. Elements from each of the exercises can be separated and treated as stand-alone exercises, or combined into short or long projects. We have been able to offer the opportunity to use sophisticated molecular modeling in the final module through funding from an NSF-ILI grant. However, many of the benefits of the research proposal can be achieved with other computer programs, or even by literature survey alone. Figure 1.Design of project-based biochemistry laboratory. Modules (projects, or portions of projects) are indicated as boxes. Each of these can be treated independently, or used as part of a larger project. Solid lines indicate some suggested paths from one module to the next. The skills and knowledge required for protein purification and design are developed in three units: (i) an introduction to critical assays needed to monitor degree of purification, including an evaluation of assay parameters; (ii) partial purification by ion-exchange techniques; and (iii) preparation of a grant proposal on protein design by mutagenesis. Brief descriptions of each of these units follow, with experimental details of each project at the end of this paper. Assays for Lysozyme Activity and Protein Concentration (4 weeks) The assays mastered during the first unit are a necessary tool for determining the purity of the enzyme during the second unit on purification by ion exchange. These assays allow an introduction to the concept of specific activity (units of enzyme activity per milligram of total protein) as a measure of purity.

    The use of LPG is continuous increase not only in the domestic field but also in the field of the transports. Consequently, there is a renewed interest for its flammability characteristics in order to decide the necessary conditions of safety. The main components of LPG are hydrocarbons containing three or four carbon atoms. The normal components of LPG are propane and butane; small concentrations of other hydrocarbons (isobutene, propylene, butane, ethane, pentane) may also be present. Different mixtures of LGP have different and physical characteristics with a different behavior during the use. Also flammability characteristics can be different according to the composition. In this paper at firsts the flammability characteristics of the main components of LGP, taken singularly, are examinated; subsequently some examples of calculation of the flammability limits of different mixture are reported [it

    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

  9. First-order symmetrizable hyperbolic formulations of Einstein's equations including lapse and shift as dynamical fields

    International Nuclear Information System (INIS)

    2002-01-01

    First-order hyperbolic systems are promising as a basis for numerical integration of Einstein's equations. In previous work, the lapse and shift have typically not been considered part of the hyperbolic system and have been prescribed independently. This can be expensive computationally, especially if the prescription involves solving elliptic equations. Therefore, including the lapse and shift in the hyperbolic system could be advantageous for numerical work. In this paper, two first-order symmetrizable hyperbolic systems are presented that include the lapse and shift as dynamical fields and have only physical characteristic speeds

  7. Zγ production at NNLO including anomalous couplings

    Campbell, John M.; Neumann, Tobias; Williams, Ciaran

    2017-11-01

    In this paper we present a next-to-next-to-leading order (NNLO) QCD calculation of the processes pp → l + l -γ and pp\\to ν \\overline{ν}γ that we have implemented in MCFM. Our calculation includes QCD corrections at NNLO both for the Standard Model (SM) and additionally in the presence of Zγγ and ZZγ anomalous couplings. We compare our implementation, obtained using the jettiness slicing approach, with a previous SM calculation and find broad agreement. Focusing on the sensitivity of our results to the slicing parameter, we show that using our setup we are able to compute NNLO cross sections with numerical uncertainties of about 0.1%, which is small compared to residual scale uncertainties of a few percent. We study potential improvements using two different jettiness definitions and the inclusion of power corrections. At √{s}=13 TeV we present phenomenological results and consider Zγ as a background to H → Zγ production. We find that, with typical cuts, the inclusion of NNLO corrections represents a small effect and loosens the extraction of limits on anomalous couplings by about 10%.

  8. Probabilistic production simulation including CHP plants

    Energy Technology Data Exchange (ETDEWEB)

    Larsen, H.V.; Palsson, H.; Ravn, H.F.

    1997-04-01

    A probabilistic production simulation method is presented for an energy system containing combined heat and power plants. The method permits incorporation of stochastic failures (forced outages) of the plants and is well suited for analysis of the dimensioning of the system, that is, for finding the appropriate types and capacities of production plants in relation to expansion planning. The method is in the tradition of similar approaches for the analysis of power systems, based on the load duration curve. The present method extends on this by considering a two-dimensional load duration curve where the two dimensions represent heat and power. The method permits the analysis of a combined heat and power system which includes all the basic relevant types of plants, viz., condensing plants, back pressure plants, extraction plants and heat plants. The focus of the method is on the situation where the heat side has priority. This implies that on the power side there may be imbalances between demand and production. The method permits quantification of the expected power overflow, the expected unserviced power demand, and the expected unserviced heat demand. It is shown that a discretization method as well as double Fourier series may be applied in algorithms based on the method. (au) 1 tab., 28 ills., 21 refs.

    Espejo, Lina María; de la Espriella, Ricardo; Hernández, José Fernando

    Metachromatic leukodystrophy (MLD) is a rare demyelinating disease (prevalence 1:40 000), also called arylsulfatase A deficiency (ARS-A), which may present with neurological and psychiatric symptoms. Clinical assessment may be difficult, due to unspecific signs and symptoms. A case is presented of a 16 year-old female patient seen in psychiatry due to behavioural changes, psychosis, and with impaired overall performance. She was initially diagnosed with schizophrenia, but the Nuclear Magnetic Resonance (NMR) scan and laboratory tests lead to the diagnosis of MLD. Copyright © 2016 Asociación Colombiana de Psiquiatría.

    2012-01-01

    We are presenting two cases of Sirenomelia (Mermaid Syndrome), which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed. PMID:26023366

    Information management can be a daunting process for clinicians, health care providers and policy makers within the health care industry. This chapter discusses the importance of information classification and information architecture in the information economy and specific challenges faced within the health care industry. The healthcare sector has industry specific requirements for information management, standards and specifications for information presentation. Classification of information based on information criticality and the value in the health care industry is discussed in this paper. Presentation of information with reference to eHealth standards and specifications for healthcare information systems and their key requirements are also discussed, as are information architecture for eHealth implementation in Australia. This chapter also touches on information management and clinical governance since the importance of information governance is discussed by various researchers and how this is becoming of value to healthcare information management.

    2017-05-01

    Francisella tularensis is a gram-negative coccobacillus that causes a condition commonly referred to as tularemia. There has been a dramatic increase in tularemia cases reported in South Dakota, many of which were challenging to diagnose due to atypical clinical manifestations. We describe an interesting case of pneumonic tularemia and summarize six similar cases, several of which presented with lung nodules suggestive of malignancy. According to the literature, this is only the third outbreak of pneumonic tularemia reported in the U.S. We believe it is important for clinicians to be aware of the increased incidence of tularemia in the area and to be vigilant in the diagnosis and management of these atypically presenting cases.

    In electron probe microanalysis the objective has always been to gain the maximum information from a sample. To this end efforts have been directed at increasing detection efficiency, reducing the size of the excitation volume, analysing more difficult specimens and improving the accuracy of quantitative measurements whilst, at the same time, attempting to minimize the complexity of the analysis. The present paper comments on the progress that has been made in this areas, focuses on the latest hardware and software developments taking place and looks forward to how these may impact on the technique of EPMA.

  1. Presenting Newtonian gravitation

    Counihan, Martin

    2007-01-01

    The basic principles of the Newtonian theory of gravitation are presented in a way which students may find more logically coherent, mathematically accessible and physically interesting than other approaches. After giving relatively simple derivations of the circular hodograph and the elliptical orbit from the inverse-square law, the concept of gravitational energy is developed from vector calculus. It is argued that the energy density of a gravitational field may reasonably be regarded as -g 2 /8πG, and that the inverse-square law may be replaced by a Schwarzschild-like force law without the need to invoke non-Euclidean geometry

    This paper proposes that there is a major error in the present perception of cancer risk from exposure to low level radiation from internal man-made fission products like strontium-90. The author's Second Event theory is discussed which advances the basis that fission products are different in radiation risk terms. Since the scientific community has been so ready to dismiss this idea out of hand, the author also explores scientific culture and scientific revolutions. The evidence that the idea is broadly right is surveyed and finally some studies that could be undertaken to prove or disprove the author's contention are outlined. (UK)

    The radiotherapy is one of the most widely spread and commonly used method in treating tumors of different localization. A detailed analysis of benefits and possible side effects along with evaluation of the risk factors allows preventing one of the most difficult complication, and namely the radiation myelopathy. The delayed form of such a disease is distinguished by a pronounced unfavorable prognosis. The presented case provoked the discussion of difficulties in performing differential diagnosis, as well as the importance of determining the localization of vulnerable tissues as regards the target organ exposed to radiotherapy.

    Huck, R.

    1990-01-01

    The presentation topic is California's approach to license application review in meeting financial assurances for the proposed Ward Valley site. The purpose of the presentation is to provide information on specific financial assurance provisions contained in 10 CFR Part 61 and how California intends to satisfy those requirements. Also, as rate setter, California intends to demonstrate how it will assure allowable costs to the rate base though a financial prudency review. The key provisions of financial assurance are: 10 CFR Section 61.61 - This provision requires an applicant to demonstrate its ability to finance licensed activities; 10 CFR Section 61.62 - This provision requires an applicant to provide assurance that sufficient funds will be available for site closure and stabilization; and 10 CFR Section 61.63 - This provision requires an applicant to provide 'a copy of a binding arrangement, such as a lease, between the applicant and the disposal site owner, so that sufficient funds will be available to cover the costs of the institutional control period.' To assist California in its determination of financial assurance compliance to be demonstrated by the applicant for Part 61 requirements, is NUREG guidance document 1199 'Standard Format and Content of a License Application for a Low-Level Radioactive Waste (LLRW) Disposal Facility.' The detailed financial assurance provisions of NUREG 1199 are then embodied in NUREG 1200, 'Standard Review Plant for the Review of a License Application for a LLRW Disposal Facility.'

    Rett syndrome, a degenerative neurological disorder of girls, has a classical presentation and typical EEG findings. The electroencephalograms (EEGs) of 7 girls whose records have been followed from the onset of symptoms to the age of 5 or more are presented. These findings are tabulated with the Clinical Staging System of Hagberg and Witt-Engerström (1986). The records show a progressive deterioration in background rhythms in waking and sleep. The abnormalities of the background activity may only become evident at 4-5 years of age or during stage 2--the Rapid Destructive Stage. The marked contrast between waking and sleep background may not occur until stage 3--the Pseudostationary Stage. In essence EEG changes appear to lag behind clinical symptomatology by 1-3 years. An unexpected, but frequent, abnormality was central spikes seen in 5 of 7 girls. They appeared to be age related and could be evoked by tactile stimulation in 2 patients. We hypothesize that the prominent 'hand washing' mannerism may be self-stimulating and related to the appearance of central spike discharges.

    This time, we would like to address copyright violations (again) - but with a twist. While previous articles focussed on “Music, videos and the risk for CERN” or on software licences, the focus is now on using photos, music and images “found” on the Web for presentations, publications and web pages…   Just recently, a video produced for CERN and published on YouTube and Facebook used background music from a contemporary popular artist. However, the people responsible failed to obtain the appropriate permission to actually use that music. They thought that having bought it on iTunes was sufficient. But it was not: “buying” means you have the right to listen, but not the right for further distribution or re-publication. As a result, the videos were pulled from YouTube and Facebook. Similarly, how many of us integrate graphics and images “found” on the Web into our presentations?  How many of us...

  7. Hyperthyroidism: an unusual case presentation.

    1998-02-01

    Hyperthyroidism is the most common disorder of the thyroid. Patients typically present with complaints consistent with a hypermetabolic state, including nervousness, weight loss, heat intolerance, palpitations, irritability, and tremor. This case report reviews a 34-year-old woman who presented with unilateral upper extremity weakness, weight gain, and an episode of atrial fibrillation, the latter coinciding with a 36-hour lack of sleep and excess alcohol and caffeine intake. Although an extensive neurologic evaluation failed to identify any abnormality, the patient's laboratory analysis revealed elevations in thyroxine (T4) and triiodothyronine (T3) levels with unsuppressed thyroid-stimulating hormone levels. Subsequent treatment with the antithyroid drug methimazole (Tapazole) provided complete relief of symptoms. This case report illustrates how health care providers can be diverted to pursue a neurologic etiology when muscle weakness presents as a unilateral symptom. Plausible alternative causes for muscle weakness and other symptoms are presented.

    Thyrotoxic crisis is a medical emergency requiring early diagnosis and urgent management, which can be challenging due to its diverse clinical presentations. While common presentations include fever, sweating, palpitations, tremors and confusion, presence of jaundice is rare. We report a 35-year-old male who presented with jaundice due to cholestasis along with other features of thyrotoxic crisis due to Graves' disease. He had a good clinical recovery with resolution of cholestasis following treatment for thyrotoxic crisis. Jaundice can be a rare manifestation of thyrotoxic crisis, and should be considered in the differential diagnosis when other clinical features of thyrotoxic crisis are present. However secondary causes of jaundice should be looked into and excluded.

With the previous information we arrived as a conclusion that is all about a patient with 28 years of age who lives in Sancti Spiritus Municipality, with White skin, male, carried on the Duane Syndrome type I, unilateral left. A light Hypermetropia was presented in both eyes as a refractive defect, accompanied by a light bilateral amplyopia in the right eye and moderate in the left eye. It is necessary to stay that the patient was under surgical criterium by esotropia of more than 15 degrees in PPM and unacceptable torticollis although the time of evolution; there were no difficulties related to the surgical act. The postoperative picture can reflect the result of the surgery.

    Die Urknallmaschine, an Austrian film by Gerd Baldauf, narrated by Norbert Frischauf (Alpha Österreich - ORF, 2009).  In CERN’s gigantic complex particles are accelerated to almost the speed of light, brought to collision and made to divide into even smaller particles. Public opinion of CERN’s research is also divided. Sceptics fear that black holes may be created. Might the goal to study the origin of the world lead to its destruction? The Austrian researcher Norbert Frischauf worked at CERN for many years. With his guidance it is possible to explore the world’s largest research centre, get a glimpse of the fascinating work the scientists do there and take a crash course in particle physics. Die Urknallmaschine will be presented on Friday, 25 June from 13:00 to 14:00 in the Main Auditorium. Language: German

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available Background: Trichinosis is a widespread zoonosis acquired by ingestion of undercooked meat infected with the larvae of Trichinella parasites. The disease has variable clinical manifestations ranging from asymptomatic to fatal. Majority of infections is caused by Trichinella spiralis, although there are some cases caused by other species. The dramatic decline of trichinosis reflects changes in industrial practices and increased public awareness. The majority of human cases are now associated with wild game meat and noncommercial pork. The case of previously healthy, young man with trichinosis is presented. The disease was determined with serologic testing and cured with albendazole. The source of infection has not been determined.Conclusions: In patients with fever, mialgias and eosinophilia infection with tissue nematodes should always be taken in consideration. In those who have recently consumed raw or undercooked pork and wild game meat we should think about trichinosis. The disease is rare in Slovenia.

    2013-01-01

    Full Text Available Diabetic myonecrosis is a frequently unrecognized complication of longstanding and poorly controlled diabetes mellitus. The clinical presentation is swelling, pain, and tenderness of the involved muscle, most commonly the thigh muscles. Management consists of conservative measures including analgesia and rest. Short-term prognosis is good, but long-term prognosis is poor with most patients dying within 5 years. Failure to properly identify this condition will expose the patient to aggressive measures that could result in increased morbidity. To our knowledge this is the first case reported in which there was involvement of multiple muscle groups including upper and lower limbs.

  15. Including gauge corrections to thermal leptogenesis

    2013-05-17

    This thesis provides the first approach of a systematic inclusion of gauge corrections to leading order to the ansatz of thermal leptogenesis. We have derived a complete expression for the integrated lepton number matrix including all resummations needed. For this purpose, a new class of diagram has been invented, namely the cylindrical diagram, which allows diverse investigations into the topic of leptogenesis such as the case of resonant leptogenesis. After a brief introduction of the topic of the baryon asymmetry in the universe and a discussion of its most promising solutions as well as their advantages and disadvantages, we have presented our framework of thermal leptogenesis. An effective model was described as well as the associated Feynman rules. The basis for using nonequilibrium quantum field theory has been built in chapter 3. At first, the main definitions have been presented for equilibrium thermal field theory, afterwards we have discussed the Kadanoff-Baym equations for systems out of equilibrium using the example of the Majorana neutrino. The equations have also been solved in the context of leptogenesis in chapter 4. Since gauge corrections play a crucial role throughout this thesis, we have also repeated the naive ansatz by replacing the free equilibrium propagator by propagators including thermal damping rates due to the Standard Model damping widths for lepton and Higgs fields. It is shown that this leads to a comparable result to the solutions of the Boltzmann equations for thermal leptogenesis. Thus it becomes obvious that Standard Model corrections are not negligible for thermal leptogenesis and therefore need to be included systematically from first principles. In order to achieve this we have started discussing the calculation of ladder rung diagrams for Majorana neutrinos using the HTL and the CTL approach in chapter 5. All gauge corrections are included in this framework and thus it has become the basis for the following considerations

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

  18. Alternating phase focussing including space charge

    Longitudinal stability can be obtained in a non-relativistic drift tube accelerator by traversing each gap as the rf accelerating field rises. However, the rising accelerating field leads to a transverse defocusing force which is usually overcome by magnetic focussing inside the drift tubes. The radio frequency quadrupole is one way of providing simultaneous longitudinal and transverse focusing without the use of magnets. One can also avoid the use of magnets by traversing alternate gaps between drift tubes as the field is rising and falling, thus providing an alternation of focussing and defocusing forces in both the longitudinal and transverse directions. The stable longitudinal phase space area is quite small, but recent efforts suggest that alternating phase focussing (APF) may permit low velocity acceleration of currents in the 100-300 ma range. This paper presents a study of the parameter space and a test of crude analytic predictions by adapting the code PARMILA, which includes space charge, to APF. 6 refs., 3 figs

    This paper presents a comprehensive assessment of historical (1990-2010) global anthropogenic particulate matter (PM) emissions including the consistent and harmonized calculation of mass-based size distribution (PM1, PM2. 5, PM10), as well as primary carbonaceous aerosols including black carbon (BC) and organic carbon (OC). The estimates were developed with the integrated assessment model GAINS, where source- and region-specific technology characteristics are explicitly included. This assessment includes a number of previously unaccounted or often misallocated emission sources, i.e. kerosene lamps, gas flaring, diesel generators, refuse burning; some of them were reported in the past for selected regions or in the context of a particular pollutant or sector but not included as part of a total estimate. Spatially, emissions were calculated for 172 source regions (as well as international shipping), presented for 25 global regions, and allocated to 0.5° × 0.5° longitude-latitude grids. No independent estimates of emissions from forest fires and savannah burning are provided and neither windblown dust nor unpaved roads emissions are included. We estimate that global emissions of PM have not changed significantly between 1990 and 2010, showing a strong decoupling from the global increase in energy consumption and, consequently, CO2 emissions, but there are significantly different regional trends, with a particularly strong increase in East Asia and Africa and a strong decline in Europe, North America, and the Pacific region. This in turn resulted in important changes in the spatial pattern of PM burden, e.g. European, North American, and Pacific contributions to global emissions dropped from nearly 30 % in 1990 to well below 15 % in 2010, while Asia's contribution grew from just over 50 % to nearly two-thirds of the global total in 2010. For all PM species considered, Asian sources represented over 60 % of the global anthropogenic total, and residential combustion

    The first HTA guidelines for Thailand included a chapter outlining a set of guidelines on how best to report the findings of health economic evaluations, based on a review of best practice and existing guidelines on the presentation of economic evaluation results from around the world. In this second edition of HTA guidelines for Thailand, the recommendations build on the first edition by using a case study to illustrate how the guidelines can be applied in a real research context. The guidelines propose that all reporting include ten key elements: defining the scope of the study, selection of comparator(s), defining the type of economic evaluation, measurement of costs, measurement of clinical effects, handling time in economic evaluation studies, handling uncertainty and sensitivity analysis, presentation of the results, discussion of the results, and disclosure of funding and authors conflict of interest.

    2015-01-01

    Background Little is known about the hemodynamic response to exercise in heart failure patients at various ages before and after heart transplantation (HT). This information is important because postoperative hemodynamics may be a predictor of survival. To investigate the hemodynamic response to HT and exercise, we grouped our patients based on preoperative age and examined their hemodynamics at rest and during exercise before and after HT. Methods and Results Ninety-four patients were evaluated at rest prior to HT with right heart catheterization at our laboratory. Of these patients, 32 were evaluated during slight supine exercise before and 1 year after HT. Postoperative evaluations were performed at rest 1 week after HT and at rest and during exercise at 4 weeks, 3 months, 6 months, and 1 year after HT. The exercise patients were divided into 2 groups based on preoperative age of ≤50 or >50 years. There were no age-dependent differences in the preoperative hemodynamic exercise responses. Hemodynamics markedly improved at rest and during exercise at 1 and 4 weeks, respectively, after HT; however, pulmonary and, in particular, ventricular filling pressures remained high during exercise at 1 year after HT, resulting in normalized pulmonary vascular resistance response but deranged total pulmonary vascular resistance response. Conclusions Our findings suggest that, (1) in patients with heart failure age ≤50 or >50 years may not affect the hemodynamic response to exercise to the same extent as in healthy persons, and (2) total pulmonary vascular resistance may be more adequate than pulmonary vascular resistance for evaluating the exercise response after HT.

    Chronic infiltration of lymphocytes into the salivary and lacrimal glands of patients with Sjögren's syndrome (SS) leads to destruction of acinar cells and loss of exocrine function. Protein kinase C-delta (PKCδ) is known to play a critical role in B-cell maintenance. Mice in which the PKCδ gene has been disrupted have a loss of B-cell tolerance, multiple organ lymphocytic infiltration, and altered apoptosis. To determine whether PKCδ contributes to the pathogenesis of SS, we quantified changes in indicators of SS in PKCδ-/- mice as a function of age. Salivary gland histology, function, the presence of autoantibodies, and cytokine expression were examined. Submandibular glands were examined for the presence of lymphocytic infiltrates, and the type of infiltrating lymphocyte and cytokine deposition was evaluated by immunohistochemistry. Serum samples were tested by autoantibody screening, which was graded by its staining pattern and intensity. Salivary gland function was determined by saliva collection at various ages. PKCδ-/- mice have reduced salivary gland function, B220+ B-cell infiltration, anti-nuclear antibody production, and elevated IFN-γ in the salivary glands as compared to PKCδ+/+ littermates. PKCδ-/- mice have exocrine gland tissue damage indicative of a SS-like phenotype. © 2011 John Wiley & Sons A/S.

    In contingency of a nuclear emergency event, requiring application of intervention measures on a federal scale, Canada has of a plan ensuring the compatibility of the plans of different provinces and serving as interface between federal and provincial authorities. Exclusive of a nuclear attack against North America, by nuclear emergency it is understood an accident resulting in radionuclide release. This is called the Plan of federal intervention in case of nuclear emergency. 'Sante Canada' is the federal authority responsible for intervention in case of nuclear emergency and it has the task of preparing and coordinating the actions on a federal scale.Should the plan be set in action and if the emergency has repercussions upon the agricultural sector, the sustaining organism will be 'Agriculture and agroalimentaire Canada' which in case of emergency acts through the channels of the National System of intervention in the agro-alimentary sector (SNIUA). The paper presents the objectives, the principles of organization and operation, the responsibilities and the plans which SNIUA has in its charge to implement in case of emergency

    1988-04-01

    This paper reviews the past and present situation of the World Oil Market and assumes future trends and possible future evolution. Low oil prices between 1950 and 1973 have contributed to an exceptional growth of oil demand during more than 20 years which was more and more supplied by OPEC. The oil shocks of 1973 and 1979 have dramatically changed this situation. Some of the most important changes have been the emergence of non-OPEC new oil producers, the growth of substitute energies, especially natural gas and nuclear power, on the supply side; and substantial decrease of energy consumption in many industrialized countries which has greatly reduced oil demand to OPEC on the demand side. Today this situation seems somewhat stabilized (after the reversal of world oil prices in 1986) and OPEC is producing around 18 million b/day as against a producing capacity of about 30 million b/day. It is generally considered that in coming years oil prices will remain relatively low (or occasionally even become lower than today) due to excess oil production capacity and relative abundance of other types of energy. However, many experts think that these trends can be reversed when oil supply will more and more concentrate again in the Middle East; but it is hard to say if this will begin in 1995, 2000, 2010.

    Full Text Available Laryngocele is a rare pathology, but because of their clinical evolution and the symptoms they generate, they should always be considered as a differential diagnosis when investigating neck masses. A laryngocele is basically a herniation of the mucosa of the laryngeal ventricle (Morgagni's ventricle arising usually from the saccular region. This herniation may remain confined to the larynx - in which case the laryngocele is internal- or expand through the thyro-hyoid membrane into the structures of the neck - thus being called an external laryngocele. Usually the laryngocele has both an internal and external component thus being a mixed laryngocele. Diagnosis of laryngoceles still relies heavily on clinical signs such as tympanism, easily depressible neck mass, indirect laryngoscopy, but is now simplified by imagistic investigations (ultrasound, CT and MRI. However, the treatment of this condition is exclusively surgical and consists of total excision of the laryngocele, as well as proper identification of the point of origin from the saccule and also the final suture of the breach in order to prevent recurrence. Investigation of possible causes of obstruction of the laryngeal ventricle should always be performed (because of the possibility of an underlying malignancy as well as a follow-up protocol of the patient, given the risk of relapse. We present a recently diagnosed case of a 32 year old man with mixed laryngocele, which we have operated in our clinic.

    The IKONOS satellite has been operational since January 2000 and was the first commercial satellite collecting imagery with 1 meter resolution. The current life expectancy of the satellite is 10 years. Since the launch, Space Imaging Inc. (the owner of the satellite) supplied IKONOS imagery to users in many vertical markets, such as: agriculture, defense, oil & gas and telecommunications. This oral presentation will give comprehensive information about IKONOS and the future: * Block II, the successor of IKONOS. Space Imaging expects to launch in 2004 a new high-resolution satellite, ensuring both continuity and (for some years) a tandem operation with IKONOS, greatly improving the availability of imagery. * Space Imaging affiliates. IKONOS imagery collected, processed and sold by regional affiliates. These regional affiliates are strategically located around the world, like Japan Space Imaging (Tokyo), Space Imaging Middle East (Dubai) and Space Imaging Eurasia (Ankara, Turkey). * Technical briefing IKONOS. IKONOS (compared to other commercial high-resolution satellites) has superior collection capabilities. Due to, the higher orbit altitude, local reception of the imagery, bi-directional scanning and the high agility of the satellite, is the IKONOS satellite capable to collect the imagery relative quickly.

    Commercial Buildings Characteristics 1992 presents statistics about the number, type, and size of commercial buildings in the United States as well as their energy-related characteristics. These data are collected in the Commercial Buildings Energy Consumption Survey (CBECS), a national survey of buildings in the commercial sector. The 1992 CBECS is the fifth in a series conducted since 1979 by the Energy Information Administration. Approximately 6,600 commercial buildings were surveyed, representing the characteristics and energy consumption of 4.8 million commercial buildings and 67.9 billion square feet of commercial floorspace nationwide. Overall, the amount of commercial floorspace in the United States increased an average of 2.4 percent annually between 1989 and 1992, while the number of commercial buildings increased an average of 2.0 percent annually.

  16. THE UPSIDE OF PRESENTISM

    2009-01-01

    Full Text Available El presentismo es visto generalmente como un mal necesario en historiografía. Este artículo explora lo positivo de esta inevitabilidad. Aplicando un enfoque filosófico al análisis discursivo en la tradición de la nueva historia cultural, se distingue -de una parte-¿ entre un uso estratégico del presentismo, y -de otra- un enfoque racionalista en historia. El artículo concluye considerando algunas implicaciones políticas en historiografía de las explicaciones racionalistas y de las explicaciones estratégicamente presentistas. Los modos de comprensión racionalistas inscriben las expectativas del pasado en las visiones del futuro; asignando al historiador el papel de profeta; y perpetuando nociones de agentes ahistóricos. En contraste, las historias estratégicamente presentistas incorporan una orientación que deliberadamente emplea las lentes y perspectivas del presente en orden a tener en cuenta supuestos y perspectivas actuales. Cuando las asunciones son examinadas en relación a las perspectivas presentistas, dichos presupuestos sueltan su rienda en el pensamiento. Dado que el presentismo es inevitable, no debe ser desestimado por completo, sino que debe ser una cuestión sondeada y examinada críticamente. Con dicho foco, el presentismo estratégico en la historiografía debe posibilitar una reflexión sobre los límites de lo que es posible pensar.

    The Office of Civilian Radioactive Waste Management (OCRWM) is responsible for the spent fuels and other wastes that will, or may, eventually be disposed of in a geological repository. The two major sources of these materials are commercial light-water reactor (LWR) spent fuel and immobilized high-level waste (HLW). Other wastes that may require long-term isolation include non-LWR spent fuels and miscellaneous sources such as activated metals. This report deals with spent fuels, but for completeness, the other sources are described briefly. Detailed characterizations are required for all of these potential repository wastes. These characteristics include physical, chemical, and radiological properties. The latter must take into account decay as a function of time. In addition, the present inventories and projected quantities of the various wastes are needed. This information has been assembled in a Characteristics Data Base which provides data in four formats: hard copy standard reports, menu-driven personal computer (PC) data bases, program-level PC data bases, and mainframe computer files. 5 refs., 3 figs., 4 tabs

    Clinical and neuroimaging findings of glioblastomas (GBM) at an early stage have rarely been described and those tumors are most probably under-diagnosed. Furthermore, their genetic alterations, to our knowledge, have never been previously reported. We report the clinical as well as neuroimaging findings of four early cases of patients with GBM. In our series, early stage GBM occurred at a mean age of 57 years. All patients had seizures as their first symptom. In all early stages, MRI showed a hyperintense signal on T2-weighted sequences and an enhancement on GdE-T1WI sequences. A hyperintense signal on diffusion sequences with a low ADC value was also found. These early observed occurrences of GBM developed rapidly and presented the MRI characteristics of classic GBM within a few weeks. The GBM size was multiplied by 32 in one month. Immunohistochemical analysis indicated the de novo nature of these tumors, i.e. absence of mutant IDH1 R132H protein expression, which is a diagnostic marker of low-grade diffuse glioma and secondary GBM. A better knowledge of early GBM presentation would allow a more suitable management of the patients and may improve their prognosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Implementing a sustainable local energy policy involves a long term reflection on the general interest, energy efficiency, distributed generation and environmental protection. Providing services on a market involves looking for activities that are profitable, if possible in the 'short-term'. The aim of this conference is to analyse the possibility of reconciling these apparently contradictory requirements and how this can be achieved. This conference brings together the best specialists from European municipalities as well as important partners for local authorities (energy agencies, service companies, institutions, etc.) in order to discuss the public-private partnerships concerning the various functions that municipalities may perform in the energy field as consumers and customers, planners and organizers of urban space and rousers as regards inhabitants and economic players of their areas.

    Since the development of quantum physics in the early part of the 1900s, this field of study has made remarkable contributions to our civilization. Some of these advances include lasers, light-emitting diodes (LED), sensors, spectroscopy, quantum dots, quantum gravity and quantum entanglements. In 1998, the NASA Langley Research Center established a quantum technology committee to monitor the progress in this area and initiated research to determine the potential of quantum technology for future NASA missions. The areas of interest in quantum technology at NASA included fundamental quantum-optics materials associated with quantum dots and quantum wells, device-oriented photonic crystals, smart optics, quantum conductors, quantum information and computing, teleportation theorem, and quantum energetics. A brief review of the work performed, the progress made in advancing these technologies, and the potential NASA applications of quantum technology will be presented.

    Mr. Mark Treasure from EDF NGL gave a presentation on industry perspectives on safety culture oversight. Mr. Treasure is the Nuclear Inspection and Oversight Manager within the Safety and Regulation Division. The presentation started with an explanation of the role of the nuclear inspection and oversight group (internal regulator), and their current approach to internal oversight of safety culture. A key element of the current internal regulatory oversight program is Management and Leadership Assessments. These are carried out by a team including management peers from other plants to enhance credibility. Findings can be linked to safety performance, and typically identify issues in areas such as accountability arrangements and strategic focus of the leadership team. Safety indicators have also been introduced to show trends in safety management and safety performance for each EDF UK nuclear power plant. A periodic nuclear safety culture survey is also carried out to identify focus areas and progress. The presentation included discussion on views of the role of the nuclear regulator. Important aspects were identified as: - Supporting the internal regulator by seeking to understand before taking enforcement action, maintaining an open dialogue and recognising that this area is complex and that there is rarely a 'silver bullet' solution. - Communication: being visible and actively discussing safety improvement, and use of language which emphasises nuclear safety rather than legal compliance. - Positive reinforcement to recognise efforts and encourage further improvement

    A short review is given of the present research status with regard to the Ion Ring Compressor. A consideration of the reactor characteristics of this fusion scheme indicates the potential for a number of technologically and economically interesting features, in particular with respect to the high-confinement characteristics expected for such minimum-B configurations. Experimental results from the RECE-program at Cornell indicate generally good gross stability of strong electron rings, including purely collisional decay, stability against field perturbations and others. Most-recent experiments have extended the ring lifetime to more than 2 x 10 5 electron orbits. Strong electron rings have been shifted over an axial distance of up to 30 cm. Experiments with magnetic-field insulated diodes indicate ion pulses of up to 300 nsec, and field insulation of up to 800 nsec when metallic electrodes are used

    In general, the porous media model and the effective thermal conductivity were used to simply the fuel assembly. The methods of calculating permeability were compared considering the flow inside a basket which includes a nuclear fuel. Detailed fuel assembly was a computational modeling and the flow characteristics were investigated. The flow inside the basket which included a fuel assembly is analyzed by CFD. As the height of the fuel assembly increases, the pressure drop linearly increased. The inertia resistance could be neglected. Three methods to calculate the permeability were compared. The permeability by the friction factor is 50% less than the permeability by wall shear stress and pressure drop.

    This report first presents the characteristics of conventional oil and gas system, and the classification of liquid and gaseous non conventional hydrocarbons, with the peculiar case of coal-bed methane. The authors then describe how source rock hydrocarbons are produced: production of shale oils and gases (horizontal drilling, hydraulic fracturing, exploitation) and of coal-bed methane and coal mine methane. In the next part, they address and discuss the environmental impact of source rock hydrocarbon production: installation footprint, water resource management, drilling fluids, fracturing fluids composition, toxicity and recycling, air pollution, induced seismicity, pollutions from other exploitation and production activities. They propose an overview of the exploitation and production of source rock gas, coal-bed gas and other non conventional gases in the world. They describe the current development and discuss their economic impacts: world oil context and trends in the USA, in Canada and other countries, impacts on the North American market, on the world oil industry, on refining industries, on the world oil balance. They analyse the economic impacts of non conventional gases: development potential, stakes for the world gas trade, consequence for gas prices, development opportunities for oil companies and for the transport sector, impact on CO 2 emissions, macro-economic impact in the case of the USA

  17. Simulation and Experimental Investigation of Structural Dynamic Frequency Characteristics Control

    Directory of Open Access Journals (Sweden)

    Bing Li

    2012-04-01

    Full Text Available In general, mechanical equipment such as cars, airplanes, and machine tools all operate with constant frequency characteristics. These constant working characteristics should be controlled if the dynamic performance of the equipment demands improvement or the dynamic characteristics is intended to change with different working conditions. Active control is a stable and beneficial method for this, but current active control methods mainly focus on vibration control for reducing the vibration amplitudes in the time domain or frequency domain. In this paper, a new method of dynamic frequency characteristics active control (DFCAC is presented for a flat plate, which can not only accomplish vibration control but also arbitrarily change the dynamic characteristics of the equipment. The proposed DFCAC algorithm is based on a neural network including two parts of the identification implement and the controller. The effectiveness of the DFCAC method is verified by several simulation and experiments, which provide desirable results.

    1988-01-01

    The authors report here a case of hemangioma of the left parietal bone which presented headache and papilledema. This patient is a 37-year-old female who had, prior to admission, complained of increasing headache for one year and blurred vision for three months. She had no history of head injury. Local physical examinations revealed a slight bulging in her left parietal region which was insensitive to palpation and not adherent to the overlying scalp. Neurological examinations revealed bilateral papilledema and an incongruous bitemporal upper quadrant defect in the visual field. All the other neurological and laboratory data were normal. A plain skull roentogenogram showed a 9 x 9 cm osteolytic and characteristic honeycomb lesion in the parietal region. Systemic bone survey revealed a similar lesion in the right tibia which was not histologically examined. A marked accumulation of isotopes was detected on the bone scintigrams at both lesions. Selective external carotid angiograms demonstrated a tumor stain fed by the superficial temporal, occipital, and middle meningial arteries. CT scans of the brain and skull clearly showed a local thickening of and structural changes in the skull bone and also a mass effect on the brain and lateral ventricle. The lesioned bone was removed en bloc and replaced by an artificial bone. It was highly vascular, but not adherent to the overlying dura. The post-operative course was uneventful, and the headache and papilledema disappeared. Hemangioma of the skull presenting marked hyperostosis, as reported above, seems to be rare. In addition, in this case, skeletal angioma without any clinical manifestation was detected. Clinical and radiological pictures of the hemangioma of the skull and other bones were briefly discussed.

  1. Generalized characteristic ratios assignment for commensurate fractional order systems with one zero.

    Tabatabaei, Mohammad

    2017-07-01

    In this paper, a new method for determination of the desired characteristic equation and zero location of commensurate fractional order systems is presented. The concept of the characteristic ratio is extended for zero-including commensurate fractional order systems. The generalized version of characteristic ratios is defined such that the time-scaling property of characteristic ratios is also preserved. The monotonicity of the magnitude frequency response is employed to assign the generalized characteristic ratios for commensurate fractional order transfer functions with one zero. A simple pattern for characteristic ratios is proposed to reach a non-overshooting step response. Then, the proposed pattern is revisited to reach a low overshoot (say for example 2%) step response. Finally, zero-including controllers such as fractional order PI or lag (lead) controllers are designed using generalized characteristic ratios assignment method. Numerical simulations are provided to show the efficiency of the so designed controllers. Copyright © 2017 ISA. Published by Elsevier Ltd. All rights reserved.

    Mikawa, Hiroji; Kato, Yomei; Kamiya, Kunio

    1980-01-01

    This paper presents a dynamic simulator and the control characteristics for a radioactive inert gas recovery plant which uses a cryogenic liquefying process. The simulator was developed to analyze the operational characteristics and is applicable to gas streams which contain nitrogen, argon, oxygen and krypton. The characteristics analysis of the pilot plant was performed after the accuracy of the simulator was checked using data obtained in fundamental experiments. The relationship between the reflux ratio and krypton concentration in the effluent gas was obtained. The decontamination factor is larger than 10 9 when the reflux ratio is more than 2. 0. The control characteristics of the plant were examined by changing its various parameters. These included the amount of gas to be treated, the heater power inside the evaporator and the liquid nitrogen level in the condenser. These characteristics agreed well with the values obtained in the pilot plant. The results show that the krypton concentration in the effluent gas increases when the liquid nitrogen level is decreased. However, in this case, the krypton concentration can be minimized by applying a feed forward control to the evaporator liquid level controller. (author)

    2012-12-01

    Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson's fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called "low dose-hypothesis", particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural.

  9. Including spatial data in nutrient balance modelling on dairy farms

    The Annual Nutrient Cycle Assessment (ANCA) calculates the nitrogen (N) and phosphorus (P) balance at a dairy farm, while taking into account the subsequent nutrient cycles of the herd, manure, soil and crop components. Since January 2016, Dutch dairy farmers are required to use ANCA in order to increase understanding of nutrient flows and to minimize nutrient losses to the environment. A nutrient balance calculates the difference between nutrient inputs and outputs. Nutrients enter the farm via purchased feed, fertilizers, deposition and fixation by legumes (nitrogen), and leave the farm via milk, livestock, manure, and roughages. A positive balance indicates to which extent N and/or P are lost to the environment via gaseous emissions (N), leaching, run-off and accumulation in soil. A negative balance indicates that N and/or P are depleted from soil. ANCA was designed to calculate average nutrient flows on farm level (for the herd, manure, soil and crop components). ANCA was not designed to perform calculations of nutrient flows at the field level, as it uses averaged nutrient inputs and outputs across all fields, and it does not include field specific soil characteristics. Land management decisions, however, such as the level of N and P application, are typically taken at the field level given the specific crop and soil characteristics. Therefore the information that ANCA provides is likely not sufficient to support farmers' decisions on land management to minimize nutrient losses to the environment. This is particularly a problem when land management and soils vary between fields. For an accurate estimate of nutrient flows in a given farming system that can be used to optimize land management, the spatial scale of nutrient inputs and outputs (and thus the effect of land management and soil variation) could be essential. Our aim was to determine the effect of the spatial scale of nutrient inputs and outputs on modelled nutrient flows and nutrient use efficiencies

    2008-01-01

    Full Text Available Nocardia spp are gram-positive, aerobic, acid-fast bacteria which exist as saprophytes in nature. Invasive disseminated infections are particularly common in immunocompromised or debilitated hosts. Superficial infections with Nocardia spp occur as a result of local trauma and contamination of the wound. Clinically, it presents as acute infection (abscesses or cellulitis, mycetoma, or sporotrichoid infection. Differential diagnosis includes eumycetoma, chromomycosis, blastomycosis, coccidioidomycosis, sporotrichosis, tuberculosis, botryomycosis, syphilis, yaws, and neoplasia. Its diagnosis is confirmed by demonstrating the causative organism in exudates (as granules, tissue specimens, or cultures. Early diagnosis will obviate need for drastic surgical measures as early institution of chemotherapy is effective in most patients. However, its diagnosis is often delayed due to diverse clinical presentations and for want of clinical suspicion, particularly in non-endemic areas. This paper presents 4 clinical forms of this not so uncommon disease, emphasizing the importance of high index of clinical suspicion, especially in non-endemic regions; and the significance of repeated examination of exudates for Nocardia granules for an early diagnosis.

    We show how integrodifferential equations typical of jet calculus can be combined with an averaging procedure to obtain jet-calculus-based results including the Mueller interference graphs. Results in longitudinal-momentum fraction x for physical quantities are higher at intermediate x and lower at large x than with the conventional ''incoherent'' jet calculus. These results resemble those of Marchesini and Webber, who used a Monte Carlo approach based on the same dynamics

  13. Including subjectivity in the teaching of Psychopathology

    Directory of Open Access Journals (Sweden)

    Octavio Domont de Serpa Junior

    2007-01-01

    Full Text Available Current psychopathology studies have often been presented in their descriptive dimension. This perspective is important for teaching because it helps the students to recognize and identify the symptomatology of each psychopathology case. However, subjectivity, the experience of suffering and interpersonal aspects are all lost in this perspective. Coming from another psychopathology tradition - existential anthropology - this paper presents practical psychopathology teaching experience which considers such dimensions as being relevant to the understanding of mental suffering. The features and limitations of such traditions are briefly reviewed to support this teaching experience. Two new modalities of practical teaching, used in the discipline of "Special Psychopathology I" offered by the Department of Psychiatry and Forensic Medicine at the medical school of the Federal University of Rio de Janeiro for students of psychology, will be presented according to descriptive case study methodology. With these activities we also expect to change the practice of teaching. Traditionally, interviewing of in-patients by a large group of students who observe passively what is happening is the center of this kind of education. We intend to develop a model of teaching which is closer to the proposal of the Brazilian Psychiatric Reform which views mental illness as a complex phenomenon, always involving the relationship that the subject establishes with the world.

  15. UNSCEAR: present and future activities

    International Nuclear Information System (INIS)

    Holm, Lars-Erik

    2000-01-01

    United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) was established in 1955. The Committee reviews the exposure of the world population to all sources of radiation under normal circumstances as well as after accidents, and is also the prime international scientific body reviewing and assessing the health risks of exposure to ionizing radiation. Its estimates have been and are still being used by major international bodies including the ICRP, IAEA, and WHO. UNSCEAR's publications form the scientific basis on which international and national agencies develop appropriate radiation protection standards for workers, patients and the general public. UNSCEAR reports yearly to the General Assembly and submits regularly comprehensive reports with detailed scientific annexes on the sources and biological effects of ionizing radiation. In 1995, UNSCEAR began a new program of review of the sources, exposure and biological effects of ionizing radiation. A comprehensive report with scientific annexes will be published in the year 2000. The report will include exposures from natural and man-made radiation sources, occupational and medical radiation exposures, and dose assessment methodologies. The biological effects will cover epidemiological evaluation of radiation-induced cancer, DNA repair and mutagenesis, hereditary effects, combined effects of radiation and other agents, as well as models, mechanisms and uncertainties of biological effects at low radiation doses. An assessment of exposures and effects of the Chernobyl accidents is also made. A brief overview is presented here of the range of subjects considered by the Committee. (author)

  16. Bilirubin present in diverse angiosperms.

    Pirone, Cary; Johnson, Jodie V; Quirke, J Martin E; Priestap, Horacio A; Lee, David

    2010-01-01

    Bilirubin is an orange-yellow tetrapyrrole produced from the breakdown of heme by mammals and some other vertebrates. Plants, algae and cyanobacteria synthesize molecules similar to bilirubin, including the protein-bound bilins and phytochromobilin which harvest or sense light. Recently, we discovered bilirubin in the arils of Strelitzia nicolai, the White Bird of Paradise Tree, which was the first example of this molecule in a higher plant. Subsequently, we identified bilirubin in both the arils and the flowers of Strelitzia reginae, the Bird of Paradise Flower. In the arils of both species, bilirubin is present as the primary pigment, and thus functions to produce colour. Previously, no tetrapyrroles were known to generate display colour in plants. We were therefore interested in determining whether bilirubin is broadly distributed in the plant kingdom and whether it contributes to colour in other species. In this paper, we use HPLC/UV and HPLC/UV/electrospray ionization-tandem mass spectrometry (HPLC/UV/ESI-MS/MS) to search for bilirubin in 10 species across diverse angiosperm lineages. Bilirubin was present in eight species from the orders Zingiberales, Arecales and Myrtales, but only contributed to colour in species within the Strelitziaceae. The wide distribution of bilirubin in angiosperms indicates the need to re-assess some metabolic details of an important and universal biosynthetic pathway in plants, and further explore its evolutionary history and function. Although colour production was limited to the Strelitziaceae in this study, further sampling may indicate otherwise.

  18. MOS modeling hierarchy including radiation effects

    International Nuclear Information System (INIS)

    Alexander, D.R.; Turfler, R.M.

    1975-01-01

    A hierarchy of modeling procedures has been developed for MOS transistors, circuit blocks, and integrated circuits which include the effects of total dose radiation and photocurrent response. The models were developed for use with the SCEPTRE circuit analysis program, but the techniques are suitable for other modern computer aided analysis programs. The modeling hierarchy permits the designer or analyst to select the level of modeling complexity consistent with circuit size, parametric information, and accuracy requirements. Improvements have been made in the implementation of important second order effects in the transistor MOS model, in the definition of MOS building block models, and in the development of composite terminal models for MOS integrated circuits

    2014-12-15

    We present a full two-fluid magnetohydrodynamic (MHD) description for a completely ionized hydrogen plasma, retaining the effects of the Hall current, electron pressure, and electron inertia. According to this description, each plasma species introduces a new spatial scale: the ion inertial length λ{sub i} and the electron inertial length λ{sub e}, which are not present in the traditional MHD description. In the present paper, we seek for possible changes in the energy power spectrum in fully developed turbulent regimes, using numerical simulations of the two-fluid equations in two-and-a-half dimensions. We have been able to reproduce different scaling laws in different spectral ranges, as it has been observed in the solar wind for the magnetic energy spectrum. At the smallest wavenumbers where plain MHD is valid, we obtain an inertial range following a Kolmogorov k{sup −5∕3} law. For intermediate wavenumbers such that λ{sub i}{sup −1}≪k≪λ{sub e}{sup −1}, the spectrum is modified to a k{sup −7∕3} power-law, as has also been obtained for Hall-MHD neglecting electron inertia terms. When electron inertia is retained, a new spectral region given by k>λ{sub e}{sup −1} arises. The power spectrum for magnetic energy in this region is given by a k{sup −11∕3} power law. Finally, when the terms of electron inertia are retained, we study the self-consistent electric field. Our results are discussed and compared with those obtained in the solar wind observations and previous simulations.

  2. Improved approach to characterizing and presenting streak camera performance

    International Nuclear Information System (INIS)

    Wiedwald, J.D.; Jones, B.A.

    1985-01-01

    The performance of a streak camera recording system is strongly linked to the technique used to amplify, detect and quantify the streaked image. At the Lawrence Livermore National Laboratory (LLNL) streak camera images have been recorded both on film and by fiber-optically coupling to charge-coupled devices (CCD's). During the development of a new process for recording these images (lens coupling the image onto a cooled CCD) the definitions of important performance characteristics such as resolution and dynamic range were re-examined. As a result of this development, these performance characteristics are now presented to the streak camera user in a more useful format than in the past. This paper describes how these techniques are used within the Laser Fusion Program at LLNL. The system resolution is presented as a modulation transfer function, including the seldom reported effects that flare and light scattering have at low spatial frequencies. Data are presented such that a user can adjust image intensifier gain and pixel averaging to optimize the useful dynamic range in any particular application

  6. Energy principle with included boundary conditions

    International Nuclear Information System (INIS)

    Lehnert, B.

    1994-01-01

    Earlier comments by the author on the limitations of the classical form of the extended energy principle are supported by a complementary analysis on the potential energy change arising from free-boundary displacements of a magnetically confined plasma. In the final formulation of the extended principle, restricted displacements, satisfying pressure continuity by means of plasma volume currents in a thin boundary layer, are replaced by unrestricted (arbitrary) displacements which can give rise to induced surface currents. It is found that these currents contribute to the change in potential energy, and that their contribution is not taken into account by such a formulation. A general expression is further given for surface currents induced by arbitrary displacements. The expression is used to reformulate the energy principle for the class of displacements which satisfy all necessary boundary conditions, including that of the pressure balance. This makes a minimization procedure of the potential energy possible, for the class of all physically relevant test functions which include the constraints imposed by the boundary conditions. Such a procedure is also consistent with a corresponding variational calculus. (Author)

  7. Addressing Stillbirth in India Must Include Men.

    2017-07-01

    Millennium Development Goal 4, to reduce child mortality, can only be achieved by reducing stillbirths globally. A confluence of medical and sociocultural factors contribute to the high stillbirth rates in India. The psychosocial aftermath of stillbirth is a well-documented public health problem, though less is known of the experience for men, particularly outside of the Western context. Therefore, men's perceptions and knowledge regarding reproductive health, as well as maternal-child health are important. Key informant interviews (n = 5) were analyzed and 28 structured interviews were conducted using a survey based on qualitative themes. Qualitative themes included men's dual burden and right to medical and reproductive decision making power. Wives were discouraged from expressing grief and pushed to conceive again. If not successful, particularly if a son was not conceived, a second wife was considered a solution. Quantitative data revealed that men with a history of stillbirths had greater anxiety and depression, perceived less social support, but had more egalitarian views towards women than men without stillbirth experience. At the same time fathers of stillbirths were more likely to be emotionally or physically abusive. Predictors of mental health, attitudes towards women, and perceived support are discussed. Patriarchal societal values, son preference, deficient women's autonomy, and sex-selective abortion perpetuate the risk for future poor infant outcomes, including stillbirth, and compounds the already higher risk of stillbirth for males. Grief interventions should explore and take into account men's perceptions, attitudes, and behaviors towards reproductive decision making.

    2014-02-15

    From first-principle fluid dynamics, complemented by a rigorous state equation accounting for critical anomalies, we discovered that expansion shock waves may occur in the vicinity of the liquid-vapor critical point in the two-phase region. Due to universality of near-critical thermodynamics, the result is valid for any common pure fluid in which molecular interactions are only short-range, namely, for so-called 3-dimensional Ising-like systems, and under the assumption of thermodynamic equilibrium. In addition to rarefaction shock waves, diverse non-classical effects are admissible, including composite compressive shock-fan-shock waves, due to the change of sign of the fundamental derivative of gasdynamics.

  15. Should Broca's area include Brodmann area 47?

    Ardila, Alfredo; Bernal, Byron; Rosselli, Monica

    2017-02-01

    Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47  connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

    Fossil fuels including coal play a key role as crucial energies in contributing to economic development in Asia. On the other hand, its limited quantity and the environmental problems causing from its usage have become a serious global issue and a countermeasure to solve such problems is very much demanded. Along with the pursuit of sustainable development, environmentally-friendly use of highly efficient fossil resources should be therefore, accompanied. Kyushu-university‧s sophisticated research through long years of accumulated experience on the fossil resources and environmental sectors together with the advanced large-scale commercial and empirical equipments will enable us to foster cooperative research and provide internship program for the future researchers. Then, this program is executed as a consignment business from the Ministry of Economy, Trade and Industry from 2007 fiscal year to 2009 fiscal year. The lecture that uses the textbooks developed by this program is scheduled to be started a course in fiscal year 2010.

This is remarkable given the central role of the characteristic roots in the theory of autoregressive processes. In the asymptotic analysis the problems appear when multiple roots are present as this implies a non-differentiablity so the δ-method does not apply, convergence rates are slow, and the asymptotic distribution is non-normal.

    2014-04-01

    Full Text Available In this paper, surface and piezoelectric effects on the vibration behavior of nanowires (NWs are investigated by using a Timoshenko beam model. The electric field equations and the governing equations of motion for the piezoelectric NWs are derived with the consideration of surface effects. By the exact solution of the governing equations, an expression for the natural frequencies of NWs with simply-supported boundary conditions is obtained. The effects of piezoelectricity and surface effects on the vibrational behavior of Timoshenko NWs are graphically illustrated. A comparison is also made between the predictions of Timoshenko beam model and those of its Euler-Bernoulli counterpart. Additionally, the present results are validated through comparison with the available data in the literature.

    The distal radioulnar joint allows the human to rotate the forearm to place the hand in a desired position to perform different tasks, without interfering with the grasping function of the hand. The ulna is the stable part of the forearm around which the radius rotates; the stability of the distal radioulnar joint is provided by the interaction between ligaments, muscles and bones. The stabilizing structures are the triangular fibrocartilage complex, the ulnocarpal ligament complex, the extensor carpi ulnaris tendon and tendon sheath, the pronator quadratus, the interosseous membrane and ligament, the bone itself and the joint capsule. The purpose of this review article is to present and illustrate the current understanding of the functional anatomy and pathomechanics of this joint.

    Computer programs for calculating the stability characteristics of a balloon tethered in a steady wind are presented. Equilibrium conditions, characteristic roots, and modal ratios are calculated for a range of discrete values of velocity for a fixed tether-line length. Separate programs are used: (1) to calculate longitudinal stability characteristics, (2) to calculate lateral stability characteristics, (3) to plot the characteristic roots versus velocity, (4) to plot the characteristic roots in root-locus form, (5) to plot the longitudinal modes of motion, and (6) to plot the lateral modes for motion. The basic equations, program listings, and the input and output data for sample cases are presented, with a brief discussion of the overall operation and limitations. The programs are based on a linearized, stability-derivative type of analysis, including balloon aerodynamics, apparent mass, buoyancy effects, and static forces which result from the tether line.

    2017-01-01

    Full Text Available In the view of optimizing regional power supply and demand, the paper makes effective planning scheduling of supply and demand side resources including energy efficiency power plant (EPP, to achieve the target of benefit, cost, and environmental constraints. In order to highlight the characteristics of different supply and demand resources in economic, environmental, and carbon constraints, three planning models with progressive constraints are constructed. Results of three models by the same example show that the best solutions to different models are different. The planning model including EPP has obvious advantages considering pollutant and carbon emission constraints, which confirms the advantages of low cost and emissions of EPP. The construction of progressive IRP models for power resources considering EPP has a certain reference value for guiding the planning and layout of EPP within other power resources and achieving cost and environmental objectives.

  8. Analysis of Smart Composite Structures Including Debonding

    Chattopadhyay, Aditi; Seeley, Charles E.

    1997-01-01

    Smart composite structures with distributed sensors and actuators have the capability to actively respond to a changing environment while offering significant weight savings and additional passive controllability through ply tailoring. Piezoelectric sensing and actuation of composite laminates is the most promising concept due to the static and dynamic control capabilities. Essential to the implementation of these smart composites are the development of accurate and efficient modeling techniques and experimental validation. This research addresses each of these important topics. A refined higher order theory is developed to model composite structures with surface bonded or embedded piezoelectric transducers. These transducers are used as both sensors and actuators for closed loop control. The theory accurately captures the transverse shear deformation through the thickness of the smart composite laminate while satisfying stress free boundary conditions on the free surfaces. The theory is extended to include the effect of debonding at the actuator-laminate interface. The developed analytical model is implemented using the finite element method utilizing an induced strain approach for computational efficiency. This allows general laminate geometries and boundary conditions to be analyzed. The state space control equations are developed to allow flexibility in the design of the control system. Circuit concepts are also discussed. Static and dynamic results of smart composite structures, obtained using the higher order theory, are correlated with available analytical data. Comparisons, including debonded laminates, are also made with a general purpose finite element code and available experimental data. Overall, very good agreement is observed. Convergence of the finite element implementation of the higher order theory is shown with exact solutions. Additional results demonstrate the utility of the developed theory to study piezoelectric actuation of composite

  9. Upper abdominal malignancies (not including esophagus)

    International Nuclear Information System (INIS)

    Rich, Tyvin A.

    1996-01-01

    Objective: This course will give an overview of the role of radiation therapy in the treatment of gastrointestinal malignancies in the upper abdomen, with an emphasis on carcinomas of the stomach, pancreas and biliary tract. For each site, information will be presented related to failure patterns with conventional surgical treatment and the indications for surgery for different stages of disease. The possible uses of radiation therapy as an adjuvant to surgical resection will be discussed as well as the use of radiation therapy alone. In addition, the combination of radiation therapy with chemotherapy will be discussed for each of these sites, as well as the information available at present as to the optimal way to combine chemotherapy with radiation therapy. Radiation therapy is not generally accepted to have a role in the treatment of patients with adenocarcinomas of the stomach. This is related to the fact that gastric cancer has been standardly treated with surgical resection alone, and delivery of high dose radiation therapy to the upper abdomen can be difficult because of the sensitivity of nearby normal tissues. Nonetheless, data on failure patterns suggest that local recurrence is common in patients with disease through the gastric wall and with positive nodes. Although there is some suggestive data to indicate that radiation therapy is effective as an adjuvant, results of an ongoing trial will be necessary for determination of the exact role of radiation therapy. Possible uses of radiation therapy as preoperative therapy or given alone will also be briefly discussed. Radiation therapy has been often used in the treatment of pancreatic adenocarcinomas, either alone or combined with surgical resection. Its use is more common for this site both because of the extremely poor prognosis of standard therapies, and because of the difficulty in performing an adequate surgical resection. Data will be reviewed suggesting that radiation therapy has a role when

  10. Langevin simulations of QCD, including fermions

    International Nuclear Information System (INIS)

    Kronfeld, A.S.

    1986-02-01

    We encounter critical slow down in updating when xi/a -> infinite and in matrix inversion (needed to include fermions) when msub(q)a -> 0. A simulation that purports to solve QCD numerically will encounter these limits, so to face the challenge in the title of this workshop, we must cure the disease of critical slow down. Physically, this critical slow down is due to the reluctance of changes at short distances to propagate to large distances. Numerically, the stability of an algorithm at short wavelengths requires a (moderately) small step size; critical slow down occurs when the effective long wavelength step size becomes tiny. The remedy for this disease is an algorithm that propagates signals quickly throughout the system; i.e. one whose effective step size is not reduced for the long wavelength conponents of the fields. (Here the effective ''step size'' is essentially an inverse decorrelation time.) To do so one must resolve various wavelengths of the system and modify the dynamics (in CPU time) of the simulation so that all modes evolve at roughly the same rate. This can be achieved by introducing Fourier transforms. I show how to implement Fourier acceleration for Langevin updating and for conjugate gradient matrix inversion. The crucial feature of these algorithms that lends them to Fourier acceleration is that they update the lattice globally; hence the Fourier transforms are computed once per sweep rather than once per hit.

    Friar, J.L.; Gibson, B.F.; Lehman, D.R.; Payne, G.L.

    1982-01-01

    Exact theoretical expressions for calculating the trinucleon S- and D-wave asymptotic normalization constants, with and without Coulomb effects, are presented. Coordinate-space Faddeev-type equations are used to generate the trinucleon wave functions, and integral relations for the asymptotic norms are derived within this framework. The definition of the asymptotic norms in the presence of the Coulomb interaction is emphasized. Numerical calculations are carried out for the s-wave NN interaction models of Malfliet and Tjon and the tensor force model of Reid. Comparison with previously published results is made. The first estimate of Coulomb effects for the D-wave asymptotic norm is given. All theoretical values are carefully compared with experiment and suggestions are made for improving the experimental situation. We find that Coulomb effects increase the 3 He S-wave asymptotic norm by less than 1% relative to that of 3 H, that Coulomb effects decrease the 3 He D-wave asymptotic norm by approximately 8% relative to that of 3 H, and that the distorted-wave Born approximation D-state parameter, D 2 , is only 1% smaller in magnitude for 3 He than for 3 H due to compensating Coulomb effects

    2001-01-01

    Positron scattering and channeling experiments require high quality (low emittance) beams. A new electrostatic optics system for extracting positrons from a moderator is presented. The system features improved efficiency of focusing and beam transport of moderated positrons emitted with angular spreads up to ± 30 , with good phase space characteristics. The presented optics also provides a high degree of freedom in controlling exit beam trajectories. The system has been installed in the LLNL Pelletron accelerator and showed great enhancement on the beam quality. On the detection side, image plates were used to measure the angular distributions of positrons transmitted through the gold crystals. The measurements demonstrate the advantages of image plates as quantitative position sensitive detectors for positrons. (orig.)

    2004-01-01

    The purpose of this report is to document the predictions and analyses performed using the seepage model for performance assessment (SMPA) for both the Topopah Spring middle nonlithophysal (Tptpmn) and lower lithophysal (Tptpll) lithostratigraphic units at Yucca Mountain, Nevada. Look-up tables of seepage flow rates into a drift (and their uncertainty) are generated by performing numerical simulations with the seepage model for many combinations of the three most important seepage-relevant parameters: the fracture permeability, the capillary-strength parameter 1/a, and the percolation flux. The percolation flux values chosen take into account flow focusing effects, which are evaluated based on a flow-focusing model. Moreover, multiple realizations of the underlying stochastic permeability field are conducted. Selected sensitivity studies are performed, including the effects of an alternative drift geometry representing a partially collapsed drift from an independent drift-degradation analysis (BSC 2004 [DIRS 166107]). The intended purpose of the seepage model is to provide results of drift-scale seepage rates under a series of parameters and scenarios in support of the Total System Performance Assessment for License Application (TSPA-LA). The SMPA is intended for the evaluation of drift-scale seepage rates under the full range of parameter values for three parameters found to be key (fracture permeability, the van Genuchten 1/a parameter, and percolation flux) and drift degradation shape scenarios in support of the TSPA-LA during the period of compliance for postclosure performance [Technical Work Plan for: Performance Assessment Unsaturated Zone (BSC 2002 [DIRS 160819], Section I-4-2-1)]. The flow-focusing model in the Topopah Spring welded (TSw) unit is intended to provide an estimate of flow focusing factors (FFFs) that (1) bridge the gap between the mountain-scale and drift-scale models, and (2) account for variability in local percolation flux due to

    2013-01-01

    Because of their relative proximity within the trans-Neptunian region, the plutinos (objects in the 3:2 mean-motion resonance with Neptune) are numerous in flux-limited catalogs, and well-studied theoretically. We perform detailed modeling of the on-sky detection biases for plutinos, with special attention to those that are simultaneously in the Kozai resonance. In addition to the normal 3:2 resonant argument libration, Kozai plutinos also show periodic oscillations in eccentricity and inclination, coupled to the argument of perihelion (ω) oscillation. Due to the mean-motion resonance, plutinos avoid coming to pericenter near Neptune's current position in the ecliptic plane. Because Kozai plutinos are restricted to certain values of ω, perihelion always occurs out of the ecliptic plane, biasing ecliptic surveys against finding these objects. The observed Kozai plutino fraction f koz obs has been measured by several surveys, finding values between 8% and 25%, while the true Kozai plutino fraction f koz true has been predicted to be between 10% and 30% by different giant planet migration simulations. We show that f koz obs varies widely depending on the ecliptic latitude and longitude of the survey, so debiasing to find the true ratio is complex. Even a survey that covers most or all of the sky will detect an apparent Kozai fraction that is different from f koz true . We present a map of the on-sky plutino Kozai fraction that would be detected by all-sky flux-limited surveys. This will be especially important for the Panoramic Survey Telescope and Rapid Response System and Large Synoptic Survey Telescope projects, which may detect large numbers of plutinos as they sweep the sky. f koz true and the distribution of the orbital elements of Kozai plutinos may be a diagnostic of giant planet migration; future migration simulations should provide details on their resonant Kozai populations.

  17. Amebiasis Presenting as Pleuropulmonary Disease

    1985-01-01

    Seven patients with amebic liver abscess presenting as pleuropulmonary disease were admitted to hospital initially because of pulmonary symptoms and were found to have amebic liver disease. Three categories of pleuropulmonary involvement included reactive inflammation of the pleura or lung, rupture of a hepatic abscess into the pleural space and rupture of a hepatic abscess into the bronchial airways. The preferred medical treatment is with metronidazole, but rupture of hepatic amebic abscess into the pleural space requires drainage in addition to medical therapy. In contrast, rupture into the bronchus may provide spontaneous drainage so that only medical therapy is needed. Recovery from amebiasis in all three categories is generally complete. Morbidity and mortality increase with failure to correctly identify amebic infection of the liver as the underlying cause. Because, in new cases, no findings specifically suggest that pleuropulmonary disease is a complication of hepatic amebic abscess, this possibility needs to be considered, especially in persons who are at risk of having been infected with amebae.

    Presentation of suspected pediatric uveitis: Pediatric uveitis is usually managed in specialized ophthalmic centers in the UK. Meaningful data acquisition in these clinics may be helpful in clinical governance, and healthcare planning in a specialty that is gradually changing due to changes in treatment choices. Retrospective analysis of prospectively acquired data in the Liverpool pediatric uveitis database was performed. Analysis of our data, based on 147 patients, with a mean age of 10 years, indicated a female to male ratio of 2:1. 99% of patients were Caucasian. Our data indicates 86% of all patients attending the uveitis clinic were diagnosed with juvenile idiopathic arthritis, followed by intermediate uveitis 5% and idiopathic uveitis 4%. 46% of patients required treatment. Systemic treatment included methotrexate (34%), prednisolone (14%), etanercept (6%), ciclosporin (6%), mycophenolate (3%), and infliximab (1%). Severe visual loss (defined by counting fingers or below vision) was seen in 10 eyes despite appropriately treated chronic uveitis. Our data shows uveitis-related ocular morbidity in a predominantly pediatric Caucasian population. Patients with severe and chronic uveitis may experience significant uveitis-related complications and subsequent visual loss despite aggressive treatment.

    Major advancements in radiation epidemiology have occurred during the last several years in studies of atomic bomb survivors, patients given medical radiation, and radiation workers, including underground miners. Risks associated with the Chernobyl accident, indoor radon and childhood exposure to I-131 have yet to be elucidated. Situations in the former Soviet Union around Chelyabinsk, a nuclear installation in the southern Urals, and in the Altai, which received radioactive fallout from weapons testing at Semipalatinsk, Kazakhstan, have the potential to provide information on the effects of chronic radiation exposure. Since Roentgen's discovery of x-rays just 100 years ago, a tremendous amount of knowledge has been accumulated about human health effects following irradiation. The 1994 UNSCEAR report contains the latest compilation and synthesis of radiation epidemiology. This overview will cover epidemiology from a radiation perspective. The different types of study methodologies will be described, followed by a kaleidoscope coverage of past and present studies; ending with some remaining questions in radiation epidemiology. This should set the stage for future chapters, and stimulate thinking about implications of the new data on radiation cancer risks

    The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma. Chemotherapy included 8 cycles of doxorubicin, vincristine, and cyclophosphamide, with alternating cycles of etoposide and ifosfamide. A year later, a second wide excision of the mass was performed, followed by bilaminate skin substitute and skin graft placement for reconstruction of the soft-tissue defect. After chemotherapy, a follow-up PET scan showed no signs of re-uptake in any soft tissue or skeletal structures. After 2 years, the patient remains in complete remission.

    We studied characteristics of past smokers according to the duration of cessation of smoking based on data from a population-based survey. Lifestyle, prevalences of various symptoms and diseases and other factors were compared among current smokers (8507 males and 2012 females), past smokers (4423 males and 684 females) and non-smokers (2431 males and 12,859 females) aged 40 years and over. Compared to current smokers, past smokers consumed more bread, milk, vegetables, fruit and black tea, and less rice, pickles, instant noodles, coffee and alcohol, had lower prevalences of cough, sputum and anorexia, participated more in cancer screening tests, weighed more, included more professional and administrative workers and had more non-smoking spouses. These characteristics resembled those of non-smokers. But past smokers had high prevalences of several cardiovascular and respiratory diseases compared to current smokers. Daily intake of coffee was inversely associated and daily intakes of fruit and milk were positively associated with the duration of abstinence from smoking after adjusting for other factors in both sexes. These results suggest that lifestyle of past smokers may contribute to risk reduction for several diseases.

    Objective: To determine the clinical preparation of primary hypothyroidism at the time of diagnosis. Design: It was an observational and prospective study. Place and Duration of Study: Civil Hospital, Karachi from 1st January 1997 to 31st December 1997. Subjects and Methods: Forty-eight consecutive cases of primary hypothyroidism were included. A detailed history with special emphasis on symptoms and signs was conducted and the findings observed were noted in previously made proforma. Results: Primary hypothyroidism was found to be 5 times more common in female patients, with male to female ratio 1:5, majority of cases (33.33%) were between 41 to 50 years of age. The common symptoms at the time of presentation were tiredness (95.8%), weakness (91.6%), weight gain (85.4%), hoarseness of voice (83.3%), cold intolerance (77.0%) and constipation (75.0%) in patients. Physical signs observed were delayed relaxation of ankle jerk (93.7%), periorbital edema (83.3%), thick tongue (62.5%), goiter (50.0%), dry and coarse skin (47.9%) in patients. Serum, TSH, T4 and T3 were performed in all cases through immunoradiometric technique. Serum TSH was markedly elevated, with normal to reduced T4 and T3 levels in all cases. Conclusion: Primary hypothyroidism was found more common in female than male of the age group 41-50 years. Weakness, tiredness, hoarseness of voice and constipation were the common symptoms noted. The diagnosis is almost certain on clinical grounds if the patient happens to have delayed relaxation of ankle jerks and periorbital puffiness. (author)

    Despite the prevalence of PowerPoint in professional and educational presentations, surprisingly little is known about how effective such presentations are. All else being equal, are PowerPoint presentations better than purely oral presentations or those that use alternative software tools? To address this question we recreated a real-world business scenario in which individuals presented to a corporate board. Participants (playing the role of the presenter) were randomly assigned to create PowerPoint, Prezi, or oral presentations, and then actually delivered the presentation live to other participants (playing the role of corporate executives). Across two experiments and on a variety of dimensions, participants evaluated PowerPoint presentations comparably to oral presentations, but evaluated Prezi presentations more favorably than both PowerPoint and oral presentations. There was some evidence that participants who viewed different types of presentations came to different conclusions about the business scenario, but no evidence that they remembered or comprehended the scenario differently. We conclude that the observed effects of presentation format are not merely the result of novelty, bias, experimenter-, or software-specific characteristics, but instead reveal a communication preference for using the panning-and-zooming animations that characterize Prezi presentations.

  20. Characteristics of coal mine ventilation air flows.

    2008-01-01

    Coal mine methane (CMM) is not only a greenhouse gas but also a wasted energy resource if not utilised. Underground coal mining is by far the most important source of fugitive methane emissions, and approximately 70% of all coal mining related methane is emitted to the atmosphere through mine ventilation air. Therefore, research and development on mine methane mitigation and utilisation now focuses on methane emitted from underground coal mines, in particular ventilation air methane (VAM) capture and utilisation. To date, most work has focused on the oxidation of very low concentration methane. These processes may be classified based on their combustion kinetic mechanisms into thermal oxidation and catalytic oxidation. VAM mitigation/utilisation technologies are generally divided into two basic categories: ancillary uses and principal uses. However, it is possible that the characteristics of ventilation air flows, for example the variations in methane concentration and the presence of certain compounds, which have not been reported so far, could make some potential VAM mitigation and utilisation technologies unfeasible if they cannot cope with the characteristics of mine site ventilation air flows. Therefore, it is important to understand the characteristics of mine ventilation air flows. Moreover, dust, hydrogen sulphide, sulphur dioxide, and other possible compounds emitted through mine ventilation air into the atmosphere are also pollutants. Therefore, this paper presents mine-site experimental results on the characteristics of mine ventilation air flows, including methane concentration and its variations, dust loadings, particle size, mineral matter of the dust, and other compounds in the ventilation air flows. The paper also discusses possible correlations between ventilation air characteristics and underground mining activities.

    any more (1980-1990). Kokaral was the first of the large islands becoming a peninsula, separating the Small Aral Sea in the north-east by joining the shoreline in the west. By 1986, the peninsula practically detached the small Aral Sea from the large Aral Sea, leaving only a narrow flow passage in the east. Since that time, the hydrological regimes of the Small and Large Seas have become separated. The construction of Kokaral dam in Kazakhstan, 12 km long and 8 m high, then completely separated the small Aral Sea from the large Aral Sea and changed the hydrological regimes of the water bodies. Level of this part of Sea became from this moment permanently higher than in the large Aral Sea on 42 m a.s.l. The eastern part of the sea, where the bed is much shallower and the slope is gentler is more subjected to shrinking then the western part. 2005 year became threshold, from which Eastern Aral Sea began new story - deviation from almost empty water body to almost 4 meters depth. Present assessment of water balance of Aral Sea and delta at whole dependent from delivery water river and drainage flow through control section of Samanbay on the Amudarya and some cross sections on the enter main collectors to the delta boundary. These hydrological characteristics accepted on the base of information from BWO Amudarya and our monitoring of allocation of different waters on the delta. Water volume and water surface area of Eastern and Western Aral Sea bowls were definite on the result RS data from Landsat. Bathymetric curves gave ability to assess dynamic levels of Seas. After series of enough water years 2002 - 2005 with average water income to south Priaralie 12.5 km3 period of water scarce years lead to sharp decrease of surface water area of the Eastern bowl from 1010,5 th.ha on average on two time with failure of level from 31,1 m up to average 28,5 m.

    Aim of investigation Hemicrania continua (HC) is an uncommon primary headache and little is known of the characteristics of such patients managed in an orofacial pain setting. This study provides clinical features of HC, its association with other disorders, and treatment outcomes of patients managed in the TMD and Orofacial Pain Clinic at the University of Minnesota. Methods A retrospective review of patient records was undertaken. Inclusion criteria were a diagnosis of HC and confirmation at follow-up. Results Six of the 1617 new patients seen between 2015 and 2017 met the selection criteria. Four patients presented with "facial pain", one with "toothache" and one with "jaw pain". All were female with mean age 55 ± 10.5 years (range = 41-69). Headache characteristics included unilateral (R:L = 1:1) pain of moderate intensity with severe exacerbations in the distribution of V 1 (1/6), V 1  + V 2 (3/6) and V 1  + V 2  + V 3 (2/6). Lacrimation and photophobia were the most common associated symptoms. Patient presentations were complicated by multiple medical and comorbid diagnoses. All were diagnosed with temporomandibular disorder (TMD). Indomethacin alone was sufficient for adequate headache control in 2/6 patients with several add-on medications providing sustained pain relief. Conclusions Comorbid pain conditions can be expected in patients with HC presenting to orofacial pain clinics. Symptom presentation varies, and multimodal treatment approach is necessary for success.

    Provided are electrochemical cells and electrolytes used to build such cells. The electrolytes include ion-supplying salts and fluorinated solvents capable of maintaining single phase solutions with the salts at between about -30.degree. C. to about 80.degree. C. The fluorinated solvents, such as fluorinated carbonates, fluorinated esters, and fluorinated esters, are less flammable than their non-fluorinated counterparts and increase safety characteristics of cells containing these solvents. The amount of fluorinated solvents in electrolytes may be between about 30% and 80% by weight not accounting weight of the salts. Fluorinated salts, such as fluoroalkyl-substituted LiPF.sub.6, fluoroalkyl-substituted LiBF.sub.4 salts, linear and cyclic imide salts as well as methide salts including fluorinated alkyl groups, may be used due to their solubility in the fluorinated solvents. In some embodiments, the electrolyte may also include a flame retardant, such as a phosphazene or, more specifically, a cyclic phosphazene and/or one or more ionic liquids.

    The article presents the development of a mathematical model of the system dynamics. Mathematical model allows forecasting the characteristics of flood effects. Model is based on a causal diagram and is presented by a system of nonlinear differential equations. Simulated characteristics are the nodes of the diagram, and edges define the functional relationships between them. The numerical solution of the system of equations using the Runge-Kutta method was obtained. Computer experiments to determine the characteristics on different time interval have been made and results of experiments have been compared with real data of real flood. The obtained results make it possible to assert that the developed model is valid. The results of study are useful in development of an information system for the operating and dispatching staff of the Ministry of the Russian Federation for Civil Defence, Emergencies and Elimination of Consequences of Natural Disasters (EMERCOM).

    ''Cold'' lesions on bone scan have been reported in a variety of disease processes, including infection, avascular necrosis, and cysts. We present two cases of children who presented with large ''cold'' areas on technetium bone scans and were treated initially for septic processes. Acute childhood leukemia frequently presents with bone or joint pain, fever, and elevation of the erythrocyte sedimentation rate. Although the diagnosis may be difficult if the characteristic clinical signs and laboratory findings are absent, the presence of anemia should alert the physician to the possibility of malignancy. Bone scanning provides a sensitive method of localizing pathology, but diagnosis requires biopsy or marrow aspiration

    Full Text Available The library of the Franciscan Monastery in Novo mesto keeps 224 early prints from the 16th century in which 175 printers’ and publishers’ devices were recorded. These were printed between 1501 and 1600 in 88 printers’ workshops across Europe. Printers’ and publishers’ devices, also called signets, were used in the 16th century as trademarks of respective printers and publishers. Spiritual and cultural ideas of the 16th century and intellectual goals of their owners are reflected in the complex humanistic motifs of signets. Most of the 16th century signets can be compared to impresas; they include a symbolic image and a short motto in Latin. This text presents some of the main characteristics of signets registered in Slovenia, such as the meaning, design features and motifs, dating from the early development of print culture in Europe.

    The aim of this retrospective hospital-based study was to elucidate the dentomaxillofacial characteristics of ectodermal dysplasia. Six Japanese individuals (one male and five female; age range, 12.7-27.2 years) underwent comprehensive examinations, including history recording, cephalometric analysis, panoramic radiography, and analysis of dental models. All the subjects had two or more major manifestations for clinical diagnosis of ectodermal dysplasia (e.g., defects of hair, teeth, nails, and sweat glands). They presented hypodontia (mean number of missing teeth, 9.5; range, 5-14), especially in the premolar region, and enamel dysplasia. Five subjects had bilateral molar occlusion, whereas one subject had unilateral molar occlusion. The common skeletal features were small facial height, maxillary hypoplasia, counterclockwise rotation of the mandible, and mandibular protrusion. Interestingly, the maxillary first molars were located in higher positions and the upper anterior facial height was smaller than the Japanese norm. The results suggest that vertical and anteroposterior maxillary growth retardation, rather than lack of occlusal support due to hypodontia, leads to reduced anterior facial height in individuals with ectodermal dysplasia. © 2014 Japanese Teratology Society.

    Full Text Available Salivary components may suffer variations that can be detected by chemical determinations. The aim of this work was to determine physical and biochemical characteristics of the saliva of a group of diabetic children compared to those of a control group. Relation to oral health indices was also determined. Twenty diabetic children (3-15-years-old and 21 control children (5-12-years-old were included in this study. Total proteins, sugars and calcium were determined by colorimetric methods, and glucose, urea, alpha-amylase and acid phosphatase by enzymatic methods. Our results demonstrated that acidic pH, diminished salivary flow rate and excess foam are usually present in saliva of diabetic children. Total sugars, glucose, urea and total proteins were greater in diabetic patients than controls, while calcium values were decreased. These differences were confirmed by the discrimination test. Diabetic children have higher DMFT-dmft-deft and DMFS-dmfs-defs values compared to those of the control children despite their lower sugar intake. Some salivary components in addition to the diminished flow rate could be involved in the characterization of the oral health state of diabetic children.

    Full Text Available The lecture gives basic information about psoriatic arthritis (PsA, a chronic inflammatory disease of the joints, spine, and enthesises from a group of spondyloarthritis. It describes the epidemiology of the disease and considers current ideas on its pathogenesis and factors influencing the development of PsA in psoriatic patients. The classification and clinical forms of PsA are presented. The major clinical manifestations of the disease are indicated to include peripheral arthritis, enthesitis, dactylitis, and spondylitis. The diagnosis of the disease is noted to be established on the basis of its detected typical clinical and radiological signs, by applying the CASPAR criteria. A dermatologist, rheumatologist, and general practitioner screen PsA, by actively detecting complaints, characteristic clinical and radiological signs of damage to the joints, and/or spine, and/or enthesises and by using screening questionnaires. There are data that patients with PsA are observed to be at higher risk for a number of diseases type 2 diabetes mellitus hypertension, coronary heart disease, obesity, metabolic syndrome, inflammatory bowel diseases, etc. The aim of current pharmacotherapy for PsA is to achieve remission or minimal activity of clinical manifestations of the disease, to delay or prevent its X-ray progression, to increase survival, to improve quality of life in patients, and to reduce the risk of comorbidities. The paper considers groups of medicines used to treat the disease, among other issues, information about biological agents (BA registered in the Russian Federation for the treatment of PsA. Most patients are mentioned to show a good response to this therapy option just 3–6 months after treatment initiation; however, some of them develop primary inefficiency. In this case, switching one BA to another is recommended. Some patients using a BA develop secondary treatment inefficiency, which is firstly due to the appearance of

    Ectodermal dysplasia is a complex group of familial disorders with numerous clinical characteristics, with an incidence of 7 in 10000 born alive children. Ectodermal dysplasia affects structures of ectodermal origin like the skin and its appendages as well as other non-ectodermal structures. The most common sites of involvement are the defects in the skin, hair, teeth, nails and sweat glands,which are of ectodermal origin. Though the dermatologists and paediatricians often manage such cases, we report one case of ectodermal dysplasia presenting with atrophic rhinitis.
