Paget's disease (PD) is a chronic metabolically active bone disease, characterized by a disturbance in bone modelling and remodelling due to an increase in osteoblastic and osteoclastic activity. The vertebra is the second most commonly affected site. This article reviews the various spinal pathomechanisms and osseous dynamics involved in producing the varied imaging appearances and their clinical relevance. Advanced imaging of osseous, articular and bone marrow manifestations of PD in all the vertebral components are presented. Pagetic changes often result in clinical symptoms including back pain, spinal stenosis and neural dysfunction. Various pathological complications due to PD involvement result in these clinical symptoms. Recognition of the imaging manifestations of spinal PD and the potential complications that cause the clinical symptoms enables accurate assessment of patients prior to appropriate management.

Full Text Available The purpose of this study was to retrospectively review the clinical characteristics and outcomes of a series of women with Paget's disease of the vulva. A retrospective review was performed of 89 women with Paget's disease of the vulva evaluated at a single institution between 1966 and 2010. Medical records were reviewed for demographic information, clinical data, pathologic findings, treatment modalities and outcomes. We found that the primary treatment was surgery for 74 (83.1% patients, with positive margins noted in 70.1% of cases. Five patients (5.6% underwent topical treatment with imiquimod and/or 5-fluorouracil, one patient (1.1% underwent laser ablation and treatment was unknown in 9 patients (10.1%. The majority of patients had multiple recurrences, with 18% having four or more recurrences. There were no significant differences in recurrence rates between patients who underwent surgery and those who did not. Furthermore, there was no association between positive margins following primary surgery and recurrence. Forty-one patients (46.1% were diagnosed with 53 synchronous or metachronous cancers. Seven patients (7.9% were found to have invasive vulvar cancer with 1 mm or more depth of invasion, but none of the patients died of Paget's disease or associated vulvar/vaginal cancer. Our findings suggest that the majority of patients with Paget's disease of the vulva develop multiple recurrences regardless of treatment modality or margin status. Alternatives to surgery are needed to better care for women with this disease.

2001-01-01

Paget's bone disease is heterogeneously distributed and several foci of high prevalence have been reported in Europe, United States, Argentina and Australia. The aim of the present work was to determine the ethnic origin of the disease in Buenos Aires using a cross sectional epidemiological study. Sample choice was based on a sampling according to grandparents' nationality. Ninety five percent of Paget patients were of European descent and 5% were non-European, while in the control group the proportion of European descendants is lower: 83% (OR: 3.7; p < 0.007; IC 95%: 1.4-9.7). Within the group of patients with Paget's disease the proportion of Italian and Russian descendants was higher than expected according to the 1914 Argentinean census. The prevalence of Paget's disease among European migrants was higher than in the control group of citizens. Regardless of environmental factors, it is likely that the migrants carried a higher risk of developing the disease

Full Text Available Abstract Background Paget's disease of bone (PDB disrupts normal bone architecture and causes pain, deformity, deafness, osteoarthritis, and fractures. Genetic factors play a role in PDB and genetic tests are now conducted for research purposes. It is thus timely to investigate the potential for a clinical programme of genetic testing and preventative treatment for people who have a family history of PDB. This study examines the beliefs of relatives of people with PDB. It focuses particularly on illness and treatment representations as predictors of the acceptability and uptake of potential clinical programmes. Illness representations are examined using Leventhal's Common Sense Self-Regulation Model while cognitions about treatment behaviours (acceptance of testing and treatment uptake are conceptualised within the Theory of Planned Behaviour. Methods/Design A postal questionnaire of non-affected relatives of people with Paget's disease. The sample will include relatives of Paget's patients with a family history of Paget's disease and relatives of Paget's patients without a family history of Paget's disease. The questionnaire will explore whether a range of factors relate to acceptability of a programme of genetic testing and preventive treatment in relatives of Paget's disease sufferers. The questionnaire will include several measures: illness representations (as measured by the Brief Illness Perceptions Questionnaire; treatment representations (as measured by Theory of Planned Behaviour-based question items, informed by a prior interview elicitation study; descriptive and demographic details; and questions exploring family environment and beliefs of other important people. Data will also be collected from family members who have been diagnosed with Paget's disease to describe the disease presentation and its distribution within a family. Discussion The answers to these measures will inform the feasibility of a programme of genetic testing and

A 54-year-old man presented with a solitary, erythematous, rapidly growing 1-cm nodule on his scalp that had arisen over the previous 3 months. He had no history of skin cancer. An excisional biopsy of the lesion showed a fairly well-circumscribed but focally invasive tumor consisting of areas of typical-appearing clear cell hidradenoma as well as areas with mucinous goblet-type cells and cells with eosinophilic cytoplasm and decapitation-type secretion. There was marked cellular atypia, numerous atypical mitotic figures and focal necrosis. The tumor cells focally involved the overlying epidermis (Paget's disease). Large areas of mucin were identified throughout the lesion. The tumor cells stained with markers for cytokeratin 7 and focally for EMA and CEA, confirming ductal differentiation. The goblet cells and mucinous areas stained with mucicarmine and PASD. The patient was diagnosed with hidradenocarcinoma with mucinous differentiation. Associated Paget's disease has only rarely been reported, and mucinous metaplasia is a previously unreported feature in hidradenocarcinoma.

A clinical case of 52 years old woman with history of periodic headaches for many years. The headache became more intensive and constant during the last 4-6 months. Instability by walking and stagger occurred as well as weakness in all 4 extremities, difficult swallowing and speech changes. Bulbar, quadripyramidal and archicerebellar symptoms were in hand. Pagets disease was ascertained engaging the skull with secondary basilar impression and compression of the cerebellum and the brain-stem leading to the above described clinical signs. Decompressive median suboccipital craniectomy was performed with laminectomy of C1. Occipital squama was thickened and highly vascularized.. Secondary basilar impression could occur in cranial Pagets disease with clinical symptoms resulting from the compression of the cerebellum and the brain-stem

Synthetic human calcitonin was used in the treatment of 26 patients over a period of 1-14 months. 17 patients had Paget's disease of the bone, 6 postmenopausal osteoporosis and 3 Sudeck's syndrome. Subjective improvement (reduction of pain, improvement of mobility) was found in 15 patients with Paget's disease, in 4 females with postmenopausal osteoporosis and in all 3 patients with Sudeck's syndrome. Radiographic improvement of bone changes developed only very slowly. These results were confirmed by diminution of the exchangeable calcium pool indicating reduction of rates of osseous degradation. Calcitonin tolerance was acceptable. Transitory nausea and occasional vomiting occurred in 3 patients.

Radiological and clinical aspects of M. Paget

International Nuclear Information System (INIS)

Reid, W.

1983-01-01

Deforming bone dystrophy according to Paget is a disease of uncertain etiology and the affected age group is above 40. Earlier manifestations are rare. The most frequent site of the pathologic process is the pelvis. Further locations are the lumbar section of the vertebral column, the sacrum, extremities, skull, and the thoracal and cervical parts of the vertebral column. The sternum, clavides, hands, feet and ribs are rarely affected. There is no predisposition by sex, but more often the right half of the body seems to be attacked. Monostotic and polyostotic incidence are noted about equally often (Scully et al. 1981). As to the overall diagnostical mode of action, the following is suggested: If a bone has been attacked by M. Paget, skeletal scintiscanning of the total body with a bone-detecting tracer has to follow. If further skeletal sections turn out to be conspicuous, they have to be X-rayed. By proceeding in this manner, firstly, the diagnose can be confirmed and, secondly, the initial findings can be documented. Pharmaceutical therapy should be attempted if patients are severely affected and if there are special indications. (orig.) [de

Intraosseous lipomata in Paget's disease: an unusual CT appearance

Robbie, M.J.; Pratsis, K.K.; Lockie, D.J.

1991-01-01

A case of multiple intraosseous lumbar vertebral lipomata is reported occurring in the prescence of Paget's disease. The pathology and radiology are correlated. An 84 year old man with Paget's disease presented after a cerebrovascular accident which caused him a mild right hemiparesis. Lumbar vertebral lesions were noted incidentally on abdominal radiographs and a CT scan was performed to define the abnormal areas. CT appearance favoured a slow growing non-invasive lesion. However, it failed to show the lower attenuation expected of a fatty lesion such as a lipoma. It is estimated that CT can be diagnostic if it does show fat level attenuation while Magnetic Resonance Imaging can define the lesion in the sagittal and coronal planes as well as provide the signal characteristics of fat (high signal on T1 and T2 weighted images) irrespective of its myxoid ground substance content

An interesting case of peripheral vascular disease, vascular reperfusion, and subsequent development of pain due to Paget's disease of bone.

To present a case of Paget's disease of bone that was unmasked after vascular reperfusion. In this case study, we review the presentation, evaluation, diagnosis, and management of a patient with Paget's disease and peripheral vascular disease. A 79-year-old-woman with a history of coronary artery heart disease and recent finding of a T5 compression fracture was hospitalized for evaluation of right lower extremity claudication. Angiography demonstrated a focal complete occlusion of the distal right femoral and popliteal arteries. A self-expanding stent was placed in the distal femoral and popliteal arteries. Approximately 48 hours after the procedure, the patient developed severe, right lower leg pain. On endocrine evaluation, the patient was found to have clinical signs suggesting Paget's disease of bone, which was subsequently confirmed by imaging. This patient's development of severe pain following reperfusion of distal femoral and popliteal arteries is in keeping with the known and aforementioned hypervascularity of pagetic bone. The finding of increased warmth over an area of skeletal deformation should always raise the possibility of Paget's disease of bone.

Paget's disease of bone is defined by an acceleration of focused bone remodeling, bone hypertrophy and abnormal bone structure of mono, oligo or poly-ostotic distribution. The evolution of the disease is characterized by a progression of lesions in the bones already partially achieved, without extending bone to bone by contiguity. We report a case of Paget bone disease interesting the dorsal spine and extending in an atypical way to the adjoining ribs. This case illustrates an atypical radio- scintigraphy of Paget's disease with direct extension of the likely damage to bone on bone in the skeletal truncal bridge to know well. (N.C.)

The mitochondrial SIR2 related protein 2 (SIR2RP2 impacts Leishmania donovani growth and infectivity.

Full Text Available Leishmania donovani, a protozoan parasite is the major causative agent of visceral leishmaniasis. Increased toxicity and resistance to the existing repertoire of drugs has been reported. Hence, an urgent need exists for identifying newer drugs and drug targets. Previous reports have shown sirtuins (Silent Information Regulator from kinetoplastids as promising drug targets. Leishmania species code for three SIR2 (Silent Information Regulator related proteins. Here, we for the first time report the functional characterization of SIR2 related protein 2 (SIR2RP2 of L. donovani.Recombinant L. donovani SIR2RP2 was expressed in E. coli and purified. The enzymatic functions of SIR2RP2 were determined. The subcellular localization of LdSIR2RP2 was done by constructing C-terminal GFP-tagged full-length LdSIR2RP2. Deletion mutants of LdSIR2RP2 were generated in Leishmania by double targeted gene replacement methodology. These null mutants were tested for their proliferation, virulence, cell cycle defects, mitochondrial functioning and sensitivity to known SIR2 inhibitors.Our data suggests that LdSIR2RP2 possesses NAD+-dependent ADP-ribosyltransferase activity. However, NAD+-dependent deacetylase and desuccinylase activities were not detected. The protein localises to the mitochondrion of the promastigotes. Gene deletion studies showed that ΔLdSIR2RP2 null mutants had restrictive growth phenotype associated with accumulation of cells in the G2/M phase and compromised mitochondrial functioning. The null mutants had attenuated infectivity. Deletion of LdSIR2RP2 resulted in increased sensitivity of the parasites to the known SIR2 inhibitors. The sirtuin inhibitors inhibited the ADP-ribosyltransferase activity of recombinant LdSIR2RP2. In conclusion, sirtuins could be used as potential new drug targets for visceral leishmaniasis.

Data takes from SIR-A and SIR-B (Shuttle Imaging Radar) crossed all of the principal geomorphic provinces of the central Andes between 17 and 34 S latitude. In conjunction with Thematic Mapping images and photographs from hand-held cameras as well as from the Large Format Camera that was flown with SIR-B, the radar images give an excellent sampling of Andean geomorphology. In particular, the radar images show new details of volcanic rocks and landforms of late Cenozoic age in the Puna, and the exhumed surfaces of tilted blocks of Precambrian crystalline basement in the Sierras Pampeanas.

The value of computer tomography was investigated in Paget's disease of the hip, femoral head necrosis (adult avascular and osteoradionecrosis), coxarthrosis and coxarthritis (bacterial and rheumatoid). The greatest value of CT is in the diagnosis of adult avascular necrosis of the femoral head and is valuable for localising the necrotic area in the axial plane. This is of value in planning surgical treatment (displacement osteotomy or endoprosthesis). In Paget's disease, coxarthrosis and coxarthritis, CT provides only additional or more precise information.

A 74-year-old man had an endoscopic type 0'-IIc tumor in the upper gastric body on the greater curvature and biopsy showed the tumor to be a well-differentiated adenocarcinoma (Group 5). He was referred to us for endoscopic submucosal dissection (ESD). Endoscopy revealed fold convergency, fold swelling, and fusion of the fold, indicating tumor invasion into the submucosa, which was outside the indications for ESD. In addition, there was an increase of serum bone-type alkaline phosphatase (ALP-III and ALP-IV) and urinary cross-linked N-terminal telopeptide of type I collagen (a bone metabolism marker), while (18)F-fluorodeoxyglucose positron emission tomography showed increased uptake in the left pelvis and Th10, suggesting bone metastases. We first diagnosed gastric cancer with bone metastases; however, the symptoms suggested pathological bone fracture and no bone pain. Therefore, a computed tomography-guided aspiration bone biopsy was performed to exclude the possibility of Paget's disease of bone. Biopsy specimens revealed no tumor and a mosaic pattern. No increased uptake of (18)F-FAMT (L-[3-(18)F] α-methyltyrosine) supported a diagnosis of no bone metastases from gastric cancer. We finally diagnosed gastric cancer accompanied by Paget's disease of bone and performed a laparoscopy-assisted proximal gastrectomy. The pathological diagnosis was U less 0-IIb, and U post 0-IIc ypT1a (M) N0H0P0M0 yp stage IA. In gastric cancer patients with suspected bone metastasis, we also need to consider Paget's disease of bone.

The measurement of regional bone accretion of calcium has proved its worth in the study of two localised bone disorders, Paget's disease and the bone complications of medullar lesions. Intraveinous injection of 47 Ca is followed during 6 days of external measurements with the human whole-body counter and daily determinations of the serum specific activity. Assuming that the decay slope of the extra-osseous activity is parallel to that which follows the serum activity between two and six days, the activity fixed on the skeleton is calculated by zones. The experiment covers 15 normal subjects, 10 patients with Paget's disease, 10 paraplegics and 28 case of miscellaneous ailments [fr

James George Frazer’s Anthropologic Heritage in the Work of Robert Graves

Directory of Open Access Journals (Sweden)

Tomislav M. Pavlović

2016-02-01

Full Text Available The works of Sir James George Frazer had an outstanding influence on the literature of modernism. Among those who benefited from Frazer’s ritualism were W. B. Yeats, T. S. Eliot. James Joyce, Ernest Hemingway, D. H. Lawrence, Ezra Pound, Mary Renault, Joseph Campbell, Robert Graves and many others. Robert Graves was known for his famous adaptation of Frazer’s concept of the sacred king who is sacrificed for the benefit of his subjects thus forming the narrative frame for the one of his most controversial novels. The dying king is also identified with the poet striving to attain the favour of the Triple Muse Goddess - who represents the embodiment of true poetic inspiration. The aforementioned concept is not the only thing that Graves inherited from his famous ancestor. In our analysis we laid stress on the customs, rituals, magic symbols and deities both authors dealt with. We also observed a striking resemblance of the style Greves and Frazer developed and their euchemeristic approach to myths as well.

Functional bracing for delayed union of a femur fracture associated with Paget's disease of the bone in an Asian patient: a case report

Directory of Open Access Journals (Sweden)

Fukuta Masashi

2010-05-01

Full Text Available Abstract Paget's disease of the bone is a common metabolic bone disease in most European countries, Australia, New Zealand, and North America. Conversely, this disease is rare in Scandinavia, Asia, and Africa. In Japan, it is extremely rare, with a prevalence of 0.15/100000. Paget's disease is a localized disorder of bone remodeling. Excessive bone resorption and abnormal bone formation result in biomechanically weakened bone and predispose patients to fracture. Delayed union and non-union of fractures have been reported in patients with Paget's disease. Therefore, open reduction and internal fixation of fractures has been recommended to prevent such complications. Here we report an unusual case of a 63-year-old Asian woman with delayed union of a femur fracture secondary to Paget's disease, which was treated successfully by functional bracing.

Bone scintigraphy and radiology in untreated Paget's disease

1985-01-01

This study is based on 107 patients with untreated Paget's disease of bone. Scintigraphy was performed 3 hours after 20 mCi Tc-99m-Sn-EHDP, using a Toshiba 204 or 404 gamma camera. In each patient multiple spot films of the total skeleton were made and evaluated according to a six-point scale. Moreover, in 42 patients the ratio of uptake in a lesion over comparable normal bone was measured using an MDS Trinary computer. Radiographs were made only of affected parts and evaluated according to a three-point scale. In 59 (16%) of the 373 lesions found on the scintigam no radiographic abnormalities were found. These roentgen-negative lesions generally show rather low scintigraphic uptake and are mostly asymptomatic. There exists a clear correlation between scintigraphic uptake and radiological deformity: the scintigraphic scores 5 and 6 occur in only 24% of the ro-grade 1 lesions, but in 65% of the grade 3 lesions; after computer evaluation the mean ratio in grade 1 and 3 lesions is 3.0 and 6.5 resp. (p<0.01). There also appears to be a correlation between scint. uptake and symptomatology: typical Pagetic pain is present in 10% of scint. score 2 and 3 lesions, but in 40% of score 5 and 6 lesions; the mean computer measured scint. ratio is 4.0 for asymptomatic and 7.5 for painful lesions (p<0.001)

We present to our knowledge the first patient with histopathologically proven brain metastasis from extramammary Paget's disease (EMPD) and discuss the effect of brain radiation therapy for this condition. A 68-year-old man presented to our hospital with headache and gait disturbance. Brain MRI showed multiple enhancing mass lesions, and two large cystic lesions in the left cerebellum. The patient had been diagnosed with scrotal Paget's disease 3 months previously but no further management had been performed due to his refusal. The patient underwent stereotactic aspiration and biopsy of the two large cystic lesions. A histopathological examination revealed that the tumor was a metastatic adenocarcinoma. Immunohistochemical staining revealed that the tumor cells were strongly positive for cytokeratin 7 and moderately positive for carcinoembryonic antigen and gross cystic disease fluid protein 15. These findings were similar to those of his scrotal skin lesions and were consistent with metastatic EMPD. The patient underwent brain radiation therapy with a total radiation dose of 30 Gy in 10 fractions. The patient improved neurologically so as to be self-ambulatory, and a mild improvement in the metastatic tumors was found on follow-up MRI. We had planned systemic chemotherapy, but the patient died of acute respiratory failure 2 months after radiation therapy. Copyright © 2013 Elsevier Ltd. All rights reserved.

[Effects of the combined calcitonin and sodium etidronate therapy in Paget's disease of bone].

Nuti, R; Turchetti, V; Righi, G; Vattimo, A

1982-03-03

The therapy of Paget's bone disease is essentially based on the use of calcitonin and diphosphonates: both drugs, if used in large doses for long periods, have shown themselves able to provoke particular side-effects. It was, therefore, decided to study the therapeutic efficacy of combined low-dosage treatment using synthetic salmon calcitonin and sodium-etidronate on a group of patients with Paget's osteodystrophy. A clear evident diminution in plasma alkaline phosphatase, hydroxyprolinuria and whole body retention (WBR) of MDP-Tc99m was observed, demonstrating a reduction of metabolic turnover in the bone. No changes in the bone mass (BMC), evaluated by bone mineral detector, were observed at the end of treatment. With this treatment the plateau effect was shown to be appreciably less than normally occurs when either calcitonin or sodium etidronate are used alone.

Sumoylation of Sir2 differentially regulates transcriptional silencing in yeast.

Hannan, Abdul; Abraham, Neethu Maria; Goyal, Siddharth; Jamir, Imlitoshi; Priyakumar, U Deva; Mishra, Krishnaveni

2015-12-02

Silent information regulator 2 (Sir2), the founding member of the conserved sirtuin family of NAD(+)-dependent histone deacetylase, regulates several physiological processes including genome stability, gene silencing, metabolism and life span in yeast. Within the nucleus, Sir2 is associated with telomere clusters in the nuclear periphery and rDNA in the nucleolus and regulates gene silencing at these genomic sites. How distribution of Sir2 between telomere and rDNA is regulated is not known. Here we show that Sir2 is sumoylated and this modification modulates the intra-nuclear distribution of Sir2. We identify Siz2 as the key SUMO ligase and show that multiple lysines in Sir2 are subject to this sumoylation activity. Mutating K215 alone counteracts the inhibitory effect of Siz2 on telomeric silencing. SUMO modification of Sir2 impairs interaction with Sir4 but not Net1 and, furthermore, SUMO modified Sir2 shows predominant nucleolar localization. Our findings demonstrate that sumoylation of Sir2 modulates distribution between telomeres and rDNA and this is likely to have implications for Sir2 function in other loci as well. © The Author(s) 2015.

A man with Paget's disease of bone was admitted with a fractured neck of femur. On admission he was normocalcaemic, but with immobilization he rapidly became hypercalcaemic, despite a normal diet and no medication. The hypercalcaemia responded to calcitonin. Although hypercalcaemia is often quoted as complicating the immobilization of such patients, well documented uncomplicated cases have rarely been reported.

16 patients suffering from Paget's disease were studied before, during and after 3 or 6 month treatment with disodium ethydronate (EHDP) per os. An appreciable improvement in pain symptomatology was noted and at times an evident improvement in audiometry; from the metabolic viewpoint there was a fall in serum alkaline phosphatase and urinary excretion of calcium and hydroxyproline. A study of radiocalcium kinetics demonstrated a reduction in the exchangeable calcium pool and the fractional turnover rate. Histological examination following needle biopsy of the iliac crest showed evident diminution in the active bone cell population (osteoclasts, osteoblasts) and, in certain cases, appearance of osteoid borders.

Moreover, in 42 patients the ratio of uptake in a lesion over comparable normal bone was measured using an MDS Trinary computer. Radiographs were made only of affected parts and evaluated according to a three-point scale. In 59 (16%) of the 373 lesions found on the scintigam no radiographic abnormalities were found. These roentgen-negative lesions generally show rather low scintigraphic uptake and are mostly asymptomatic. There exists a clear correlation between scintigraphic uptake and radiological deformity: the scintigraphic scores 5 and 6 occur in only 24% of the ro-grade 1 lesions, but in 65% of the grade 3 lesions; after computer evaluation the mean ratio in grade 1 and 3 lesions is 3.0 and 6.5 resp. (p<0.01). There also appears to be a correlation between scint. uptake and symptomatology: typical Pagetic pain is present in 10% of scint. score 2 and 3 lesions, but in 40% of score 5 and 6 lesions; the mean computer measured scint. ratio is 4.0 for asymptomatic and 7.5 for painful lesions (p<0.001).

We describe a patient with Klinefelter's syndrome associated with multi-focal breast carcinoma and Paget's disease of the nipple. Reviewing the 16 previously documented cases in the world literature, it is apparent that patients with this syndrome have an increased incidence of breast carcinoma. There is no evidence to date to suggest that such tumour is morphologically or biologically different from breast cancer in females and normal men.

Extramammary Paget disease of the vulva (EPDV) is a rare occurrence with an indolent and relapsing course. Progression to invasion occurs in 4% to 19% of cases. The aim of this study is to report clinical-pathological features and outcomes of patients treated for invasive EPDV. Data of consecutive patients treated between 2000 and 2017 for invasive EPDV were reviewed. Among 79 patients with EPDV, 10 (12.7%) presented a microinvasive or invasive form at first diagnosis or during follow-up. All of them underwent upfront radical surgery; 7 (70%) received subsequent radiotherapy, chemotherapy, or both. The mortality rate was 40%. The recurrence rate after treatment for invasive forms was 60%, with a mean time to first recurrence of 20 (range, 5-36) months. Our study confirms that invasive EPDV remains a rare gynecological neoplasm with a poor prognosis. Multicentre trials or well-organized prospective data collection could improve the knowledge about the management of invasive EPDV.

In Staphylococcus epidermidis and Staphylococcus aureus, a number of cell wall- and cytoplasmic membrane-associated lipoproteins are induced in response to iron starvation. To gain insights into the molecular basis of iron-dependent gene regulation in the staphylococci, we sequenced the DNA upstream of the 3-kb S. epidermidis sitABC operon, which Northern blot analysis indicates is transcriptionally regulated by the growth medium iron content. We identified two DNA sequences which are homologous to elements of the Corynebacterium diphtheriae DtxR regulon, which controls, in response to iron stress, for example, production of diphtheria toxin, siderophore, and a heme oxygenase. Upstream of the sitABC operon and divergently transcribed lies a 645-bp open reading frame (ORF), which codes for a polypeptide of approximately 25 kDa with homology to the DtxR family of metal-dependent repressor proteins. This ORF has been designated SirR (staphylococcal iron regulator repressor). Within the sitABC promoter/operator region, we also located a region of dyad symmetry overlapping the transcriptional start of sitABC which shows high homology to the DtxR operator consensus sequence, suggesting that this region, termed the Sir box, is the SirR-binding site. The SirR protein was overexpressed, purified, and used in DNA mobility shift assays; SirR retarded the migration of a synthetic oligonucleotide based on the Sir box in a metal (Fe2+ or Mn2+)-dependent manner, providing confirmatory evidence that this motif is the SirR-binding site. Furthermore, Southern blot analysis of staphylococcal chromosomal DNA with the synthetic Sir box as a probe confirmed that there are at least five Sir boxes in the S. epidermidis genome and at least three in the genome of S. aureus, suggesting that SirR controls the expression of multiple target genes. Using a monospecific polyclonal antibody raised against SirR to probe Western blots of whole-cell lysates of S. aureus, S. carnosus, S. epidermidis

Prostate-specific membrane antigen (PSMA)-targeted PET imaging is an emerging technique for evaluating patients with prostate cancer (PCa) in a variety of clinical contexts. As with any new imaging modality, there are interpretive pitfalls that are beginning to be recognized. In this image report, we describe the findings in a 63-year-old male with biochemically recurrent PCa after radical prostatectomy who was imaged with 18 F-DCFPyL, a small molecule inhibitor of PSMA. Diffuse radiotracer uptake was noted throughout the sacrum, corresponding to imaging findings on contrast-enhanced CT, bone scan, and pelvic MRI consistent with Paget's disease of bone. The uptake of 18 F-DCFPyL in Paget's disease is most likely due to hyperemia and increased radiotracer delivery. In light of the overlap in patients affected by PCa and Paget's, it is important for nuclear medicine physicians and radiologists interpreting PSMA PET/CT scans to be aware of the potential for this diagnostic pitfall. Correlation to findings on conventional imaging such as diagnostic CT and bone scan can help confirm the diagnosis.

A Novel Method of SIR Measurement for Power Control in CDMA Systems

2006-01-01

CDMA is interference limited multiple access system. Power control is an effective way to reduce co-channel interference and solve the near-far problem. Consequently, it can improve the system capacity, and make higher data rate possible. CDMA2000 employs fast closed-loop power control in reverse link to combat channel fading, and the estimation of signal to interference ratio (SIR) is required for closed-loop power control. Transmitting power is adjusted by comparing the SIR estimation with SIR target. So, it is crucial to measure the SIR of received signal accurately. Traditional measurement methods mostly depend on pilot signal strongly, when the pilots are few, there is a greater error brought to the measurement of SIR. In this paper, we discuss the SIR measurement of the received signal under the fewer pilots condition (especially only one pilot symbol) and present a novel SIR measurement method. According to the simulation, the numerical results indicate that the SIR measured by the proposed method is more accurate than the SIR measured by conventional method under fewer pilots condition

1999-01-01

In June 1998, the NIST sent to the International Reference System (SIR) a solution of 153 Sm standardized in a 4π ionization chamber. As this radionuclide had not previously been measured in the SIR, the resulting equivalent activity A e,NIST is compared with the value calculated from the efficiency curve of the SIR. However, problems occurred owing to the presence of 154 Eu and 156 Eu impurities in the solution. The manner in which the final equivalent activity value for this solution of 153 Sm has been deduced is described in this report. (authors)

Kenelm Digby was a man with widely differing interests. He studied at Oxford but left without a degree. At the age of 20, he was involved in a dramatic street brawl in Madrid; the following year saw him as a successful privateer in the Mediterranean and adjacent Atlantic waters, and he was then appointed a naval administrator with lucrative trade monopolies. He practised medicine without formal qualifications and gained notoriety by promoting the use of 'sympathetic' powder for healing wounds. Befriended by King James I and his son who succeeded him, he became chancellor to Queen Henrietta and was knighted by King James I on 21 October 1623 and appointed to the Privy Council. At one time, he even spent a brief time in prison, but he later became a founding member of the Royal Society and published two major philosophical treatises as well as a popular cookbook. He designed and manufactured wine bottles with tapered necks for simpler pouring and square sides for easy stacking. He dabbled in mathematics and corresponded with Fermat of 'Last Theorem' fame. In 1641, he challenged a French nobleman who publicly cast a slur on the British King to a 'digladiation' (a sword duel) and quickly dispatched him. He was a friend and admirer of Sir Thomas Browne whose 'Religio Medici' he helped to publish. The Cowlishaw Library holds a 1659 5th edition copy of this remarkable book, with Digby's name on the spine. Truly, Digby must qualify as a Renaissance man. © 2011 The Author.

2017-11-01

Systemic Inflammatory Response Syndrome (SIRS) and sepsis remain leading causes of death. Despite many similarities, the two entities are very distinct clinically and immunologically. T-Lymphocytes play a key pivotal role in the pathogenesis and ultimately outcome following both SIRS and sepsis. Integrins are essential in the trafficking and migration of lymphocytes. They also serve vital roles in efficient wound healing and clearance of infections. Here, we investigate whether integrin expression, specifically β1 (CD29) and β2 (CD18), are disrupted in SIRS and sepsis, and assess differences in integrin expression between these two critically ill clinical categories. T-Lymphocytes were isolated from whole blood collected from ICU patients exhibiting SIRS or sepsis. Samples were analyzed for CD18 (β2) and CD29 (β1) on CD3 + T cells through flow cytometry. Septic patients were stratified into either exclusively abdominal or non-abdominal sources of sepsis. CD18 was almost ubiquitously expressed on CD3 + T cells irrespective of clinical condition. However, CD29 (β1 integrin) was lowest in SIRS patients (20.4% of CD3 + T cells) when compared with either septic patients (35.5%) or healthy volunteers (54.1%). Furthermore, there was evidence of compartmentalization in septic patients, where abdominal sources had a greater percentage of CD3 + CD29 + T cells (41.7%) when compared with those with non-abdominal sources (29.5%). Distinct differences in T-cell integrin expression exists between patients in SIRS versus sepsis, as well as relative to the source of sepsis. Further work is needed to understand cause and effect relative to the progression from SIRS into sepsis.

Psychologists are faced with formidable challenges in making their assessment methods relevant to growing numbers of Hispanic clients for whom English is not the primary or preferred language. Among other clinical issues, the determination of malingering has profound consequences for clients. In this investigation, we evaluated a Spanish translation of the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) with 80 Spanish-speaking Hispanic American outpatients. Using a between-subjects simulation design, the Spanish SIRS was found to produce reliable results with small standard errors of measurement. Regarding validity, very large effect sizes (mean Cohen's d= 2.00) were observed between feigners and honest responders for the SIRS primary scales. We consider the potential role of the Spanish SIRS with reference to Spanish translations for other assessment instruments.

Full Text Available Abstract Background Sepsis is an infection which has evoked a systemic inflammatory response. Clinically, the Systemic Inflammatory Response Syndrome (SIRS is identified by two or more symptoms including fever or hypothermia, tachycardia, tachypnoea and change in blood leucocyte count. The relationship between SIRS symptoms and morbidity and mortality in medical emergency ward patients is unknown. Methods We conducted a prospective cohort study of the frequency of SIRS and its relationship to sepsis and death among acutely hospitalised medical patients. In 437 consecutive patients, SIRS status, blood pressure, infection and comorbidity on admission was registered together with 28-day mortality. Results A hundred and fifty-four patients (35% had SIRS on admission, 211 patients (48% had no SIRS, and 72 patients (16% had insufficient data to evaluate their SIRS status. SIRS patients were 2.2 times more frequently infected, with 66/154 SIRS patients versus 41/211 non-SIRS patients: p Conclusion We found SIRS status on admission to be moderately associated with infection and strongly related to 28-day mortality.

Effects of carbocalcitonin treatment on PAGET's disease assessed by quantitative bone scintigraphy

1988-01-01

Sixteen patients with PAGET's disease of bone underwent quantitative bone scintigraphy with 99m Tc-MDP before and after a long-term treatment with carbocalcitonin, a synthetic analogue of eel calcitonin. The radionuclide study consisted in the blood pool and bone uptake measurement and in the bone avidity calculation (bone uptake - blood pool ratio). In our patients, a significant decrease in bone uptake and bone avidity was found, whereas the blood pool remained statistically unchanged. This behaviour could be accounted for the shift of the compact bone to a lamellar pattern. (orig.) [de

SirT1 regulates energy metabolism and response to caloric restriction in mice.

Directory of Open Access Journals (Sweden)

Gino Boily

Full Text Available The yeast sir2 gene and its orthologues in Drosophila and C. elegans have well-established roles in lifespan determination and response to caloric restriction. We have studied mice carrying two null alleles for SirT1, the mammalian orthologue of sir2, and found that these animals inefficiently utilize ingested food. These mice are hypermetabolic, contain inefficient liver mitochondria, and have elevated rates of lipid oxidation. When challenged with a 40% reduction in caloric intake, normal mice maintained their metabolic rate and increased their physical activity while the metabolic rate of SirT1-null mice dropped and their activity did not increase. Moreover, CR did not extend lifespan of SirT1-null mice. Thus, SirT1 is an important regulator of energy metabolism and, like its orthologues from simpler eukaryotes, the SirT1 protein appears to be required for a normal response to caloric restriction.

The Spaceborne Imaging Radar-C (SIR-C) was a radar system, which successfully operated on two separate shuttle missions in April and October 1994. During these two missions, a total of 143 hours of radar data were recorded. SIR-C was the first multifrequency and polarimetric spaceborne radar system, operating in dual frequency (L- and C- band) and with quad-polarization. SIR-C had a variety of different operating modes, which are innovative even from today's point of view. Depending on the mode, it was possible to acquire data with different polarizations and carrier frequency combinations. Additionally, different swaths and bandwidths could be used during the data collection and it was possible to receive data with two antennas in the along-track direction.The United States Geological Survey (USGS) distributes the synthetic aperture radar (SAR) images as single-look complex (SLC) and multi-look complex (MLC) products. Unfortunately, since June 2005 the SIR-C processor has been inoperable and not repairable. All acquired SLC and MLC images were processed with a course resolution of 100 m with the goal of generating a quick look. These images are however not well suited for scientific analysis. Only a small percentage of the acquired data has been processed as full resolution SAR images and the unprocessed high resolution data cannot be processed any more at the moment.At the Alaska Satellite Facility (ASF) a new processor was developed to process binary SIR-C data to full resolution SAR images. ASF is planning to process the entire recoverable SIR-C archive to full resolution SLCs, MLCs and high resolution geocoded image products. ASF will make these products available to the science community through their existing data archiving and distribution system.The final paper will describe the new processor and analyze the challenges of reprocessing the SIR-C data.

Dual photon absorptiometry in patients with Paget disease (bone mineral contents of lumbar spine and femoral neck)

1988-01-01

The bone mineral contents (BMC) of the lumbar spine (84 cases) and of one femoral neck (53 cases) were measured by dual photon absorptiometry (DPA) in patients suffering from Paget's disease of bone. The BMC of the patients and of 53 controls were compared, taking into account the occurrence of a scintigraphic hyperfixation, in each patient. A hyperfixation of the technetium labelled diphosphonate in the lumbar spine, more frequent in males, was associated with an elevated mean BMC value. The difference versus controls was significant in men but not in women. A hyperfixation of the femoral neck was associated with an elevated mean BMC value in both sexes. BMC values greater than the mean BMC of controls + 2 SD were observed in 83 per cent of these male patients and 50 per cent of the females. In contrast, BMC values lower than in controls were observed in non-pagetic areas. DPA allows the quantification of these abnormalities which cannot be evidenced by bone scintigraphy even if alkaline phosphatases levels are assayed [fr

Paget breast disease is a kind of intraductal carcinoma that through an intracanalicular diffusion invades the basal epidermal layer, reaching the areola and nipple, producing a typical erythematous desquamative eczematous-like lesion. This neoplasia can remain undetected for a long time and inadequately treated as a dermatological affection. Synchronous or metachronous lesions are very uncommon. Surgical choice is conditioned by the presence of a tumor below the epidermal lesion, by its dimensions, and by the possible lymph node involvement. Surgical therapy can be radical or conservative. From our experience we think that lesion biopsy is always necessary to formulate a correct diagnosis and to schedule an appropriate therapeutic approach. In our case, a biopsy was performed first, then on the basis of the frozen section analysis a radical mastectomy with axillary third level lymph nodes dissection, because of the large dimensions of the lesion and the previous history of a methachronous lesion.

Development of SIR-C Ground Calibration Equipment

SIR-C/X-SAR is currently scheduled for launch in April 1994. SIR-C is an L-Band and C-Band, multi-polarization spaceborne SAR system developed by NASA/JPL. X- SAR is an X-Band SAR system developed by DARA/ASI. One of the problems involved in calibrating the SIR-C instrument is to make sure that the horizontal (H) and vertical (V) polarized beams are aligned in the azimuth direction, i.e.. that they are pointing in the same direction. This is important if the polarimetric performance specifications for the system are to be met. To solve this problem, we have designed and built a prototype of a low-cost ground receiver capable of recording received power from two antennas, one H-polarized, the other V-polarized. The two signals are mixed to audio then recorded on the left and right stereo channels of a standard audio cassette player. The audio cassette recording can then be played back directly into a Macintosh computer, where it is digitized. Analysis of.

Extramammary Paget disease (EMPD) is a rare skin disease commonly found in the anogenital region. In this study, we aimed to identify EMPD patients seen in the non-melanoma skin cancer clinic at Odette Cancer Centre and to describe the treatments delivered and outcomes achieved. From 2000 to 2009, 14 patients were seen. Initial treatment recommendations included imiquimod and surgical excision, although half the patients required more than one treatment modality, highlighting the difficulty of achieving complete eradication of this disease.

Nicotinamide clearance by Pnc1 directly regulates Sir2-mediated silencing and longevity.

Science.gov (United States)

Gallo, Christopher M; Smith, Daniel L; Smith, Jeffrey S

2004-02-01

The Saccharomyces cerevisiae Sir2 protein is an NAD(+)-dependent histone deacetylase (HDAC) that functions in transcriptional silencing and longevity. The NAD(+) salvage pathway protein, Npt1, regulates Sir2-mediated processes by maintaining a sufficiently high intracellular NAD(+) concentration. However, another NAD(+) salvage pathway component, Pnc1, modulates silencing independently of the NAD(+) concentration. Nicotinamide (NAM) is a by-product of the Sir2 deacetylase reaction and is a natural Sir2 inhibitor. Pnc1 is a nicotinamidase that converts NAM to nicotinic acid. Here we show that recombinant Pnc1 stimulates Sir2 HDAC activity in vitro by preventing the accumulation of NAM produced by Sir2. In vivo, telomeric, rDNA, and HM silencing are differentially sensitive to inhibition by NAM. Furthermore, PNC1 overexpression suppresses the inhibitory effect of exogenously added NAM on silencing, life span, and Hst1-mediated transcriptional repression. Finally, we show that stress suppresses the inhibitory effect of NAM through the induction of PNC1 expression. Pnc1, therefore, positively regulates Sir2-mediated silencing and longevity by preventing the accumulation of intracellular NAM during times of stress.

Regulating repression: roles for the sir4 N-terminus in linker DNA protection and stabilization of epigenetic states.

Directory of Open Access Journals (Sweden)

Stephanie Kueng

Full Text Available Silent information regulator proteins Sir2, Sir3, and Sir4 form a heterotrimeric complex that represses transcription at subtelomeric regions and homothallic mating type (HM loci in budding yeast. We have performed a detailed biochemical and genetic analysis of the largest Sir protein, Sir4. The N-terminal half of Sir4 is dispensable for SIR-mediated repression of HM loci in vivo, except in strains that lack Yku70 or have weak silencer elements. For HM silencing in these cells, the C-terminal domain (Sir4C, residues 747-1,358 must be complemented with an N-terminal domain (Sir4N; residues 1-270, expressed either independently or as a fusion with Sir4C. Nonetheless, recombinant Sir4C can form a complex with Sir2 and Sir3 in vitro, is catalytically active, and has sedimentation properties similar to a full-length Sir4-containing SIR complex. Sir4C-containing SIR complexes bind nucleosomal arrays and protect linker DNA from nucleolytic digestion, but less effectively than wild-type SIR complexes. Consistently, full-length Sir4 is required for the complete repression of subtelomeric genes. Supporting the notion that the Sir4 N-terminus is a regulatory domain, we find it extensively phosphorylated on cyclin-dependent kinase consensus sites, some being hyperphosphorylated during mitosis. Mutation of two major phosphoacceptor sites (S63 and S84 derepresses natural subtelomeric genes when combined with a serendipitous mutation (P2A, which alone can enhance the stability of either the repressed or active state. The triple mutation confers resistance to rapamycin-induced stress and a loss of subtelomeric repression. We conclude that the Sir4 N-terminus plays two roles in SIR-mediated silencing: it contributes to epigenetic repression by stabilizing the SIR-mediated protection of linker DNA; and, as a target of phosphorylation, it can destabilize silencing in a regulated manner.

2014-07-01

Toker cells are epithelial clear cells found in the areolar and nipple areas of the breast, vulvar region, and other apocrine gland-bearing areas of the skin. Toker cells have been implicated in the pathogenesis of clear cell papulosis, cutaneous hamartoma with pagetoid cells, and rare cases of primary extramammary Paget disease (EMPD) but not in secondary EMPD with underlying adenocarcinoma. The pathogenesis of primary EMPD is not well defined. We report a case of multicentric primary EMPD with evidence of Toker cell proliferation and nonaggressive biologic behavior in a 63-year-old white man. A detailed description of the morphologic and biologic features of Toker cells and their possible carcinogenetic links also are discussed. Based on the observation and follow-up of our patient, we hypothesize that multicentric primary EMPD starts with Toker cell hyperplasia and can potentially evolve to carcinoma in the genital region.

We examined the incidence and modern national trends in the management of Paget's disease (PD), including the use of breast-conserving surgery (BCS), mastectomy, axillary surgery, and receipt of radiotherapy. Using surveillance, epidemiology and end results (SEER) data, we identified 2631 patients diagnosed with PD during 2000-2011. Of these patients, 185 (7%) had PD of the nipple only, 953 (36.2%) had PD with ductal carcinoma in situ (PD-DCIS), and 1493 (56.7%) had PD with invasive ductal carcinoma (PD-IDC). Trends in age-adjusted incidence, primary surgery, sentinel lymph node biopsy (SLNB), and axillary lymph node dissection were examined. Multivariable logistic regression was used to evaluate factors associated with receipt of BCS and radiotherapy. A decrease in the age-adjusted incidence of PD occurred from 2000 to 2011 (-4.3% per year, p modern trends in local therapy suggest that BCS, SLNB, and adjuvant radiotherapy remain underutilized.

St. James marine terminal facility description

Energy Technology Data Exchange (ETDEWEB)

1993-10-01

The US Department of Energy (DOE) currently owns and operates a marine terminal on the west bank of the Mississippi River at St. James, Louisiana. The St. James facility was constructed by the Department to provide marine services associated with the fill and drawdown of the Strategic Petroleum Reserve (SPR) crude oil storage facilities located at Bayou Choctaw and Weeks Island, Louisiana. Although strategic to the mission of the SPR in the event of a national emergency, the St. James terminal is situated such that it has a high potential to also serve the commercial industry`s needs for crude oil terminalling and storage. The St. James terminal is located approximately 45 miles west of New Orleans and 30 miles southeast of Baton Rouge, and approximately 160 miles upstream from the mouth of the Mississippi River. Construction of the St. James terminal was initiated in 1978 and was completed in 1980. Since then, the terminal has received and transferred over 125 million barrels of crude oil to the SPR sites for storage. For crude oil distribution, the St. James terminal was connected to the neighboring LOCAP terminal by a 0.1 mile 36-inch pipeline in 1981 and to the Capline terminal by a 0.5 mile 30-inch pipeline in 1988. The terminal also has a 30-inch pipeline connection to the Koch oil terminal which was used for initial fill purposes; however, this pipeline has been disconnected and is currently inactive. A complete description of the St. James terminal facilities, operational capabilities, operational certifications, and future Government requirements are presented in Sections 2, 3, 4, and 5 respectively.

Effects of carbocalcitonin treatment on PAGET's disease assessed by quantitative bone scintigraphy

Energy Technology Data Exchange (ETDEWEB)

Vattimo, A.; Di Maggio, G.; Burroni, L.

1988-06-01

Sixteen patients with PAGET's disease of bone underwent quantitative bone scintigraphy with /sup 99m/Tc-MDP before and after a long-term treatment with carbocalcitonin, a synthetic analogue of eel calcitonin. The radionuclide study consisted in the blood pool and bone uptake measurement and in the bone avidity calculation (bone uptake - blood pool ratio). In our patients, a significant decrease in bone uptake and bone avidity was found, whereas the blood pool remained statistically unchanged. This behaviour could be accounted for the shift of the compact bone to a lamellar pattern.

Constitutive Relation of Engineering Material Based on SIR Model and HAM

Directory of Open Access Journals (Sweden)

Haoxiang He

2014-01-01

Full Text Available As an epidemic mathematical model, the SIR model represents the transition of the Susceptible, Infected, and Recovered. The profound implication of the SIR model is viewed as the propagation and dynamic evolutionary process of the different internal components and the characteristics in a complex system subject to external effect. The uniaxial stress-strain curve of engineering material represents the basic constitutive relation, which also represents the damage propagation in the units of the damaged member. Hence, a novel dynamic stress-strain model is established based on the SIR model. The analytical solution and the approximate solution for the proposed model are represented according to the homotopy analysis method (HAM, and the relationship of the solution and the size effect and the strain rate is discussed. In addition, an experiment on the size effect of confined concrete is carried out and the solution of SIR model is suitable for simulation. The results show that the mechanical mechanism of the parameters of the uniaxial stress-strain model proposed in this paper reflects the actual characteristics of the materials. The solution of the SIR model can fully and accurately show the change of the mechanical performance and the influence of the size effect and the strain rate.

Mays, Simon

2010-08-01

The strong genetic component in the etiology of Paget's disease of bone (PDB), together with marked geographic variation in its prevalence, with high frequencies in British populations, has led some to suggest that the disease originated in Britain and spread around the world in recent times by the migration and admixture of British populations. This study aims to investigate this hypothesis by studying the world geographic distribution of PDB cases identified in ancient skeletons excavated from archaeological sites. The methodology is a review of PDB cases described in the literature. There were 109 cases that met modern diagnostic criteria. All came from Western Europe, 94% from England. These data support the hypothesis that PDB originated in this geographic region.

The European SMART-1 mission to the Moon, primarily a testbed for innovative technologies, was launched in September 2003 and will reach the Moon in 2005. On board are several scientific instruments, including the point-spectrometer SMART-1 Infrared Spectrometer (SIR). Taking into account the capabilities of the SMART-1 mission and the SIR instrument in particular, as well as the open questions in lunar science, a selection of targets for SIR observations has been compiled. SIR can address at least five topics: (1) Surface/regolith processes; (2) Lunar volcanism; (3) Lunar crust structure; (4) Search for spectral signatures of ices at the lunar poles; and (5) Ground truth and study of geometric effects on the spectral shape. For each topic we will discuss specific observation modes, necessary to achieve our scientific goals. The majority of SIR targets will be observed in the nadir-tracking mode. More than 100 targets, which require off-nadir pointing and off-nadir tracking, are planned. It is expected that results of SIR observations will significantly increase our understanding of the Moon. Since the exact arrival date and the orbital parameters of the SMART-1 spacecraft are not known yet, a more detailed planning of the scientific observations will follow in the near future.

Three different 90Y internally administered radionuclide therapies are currently used in both standard-of-care and clinical trial procedures atMD Anderson Cancer Center. TheraSphere and SIR-Spheres therapies utilize 90Y-labeled microspheres, while Zevalin is an 90Y-labeled radioimmunotherapeutic agent. Several publications have indicated radionuclidic impurities resulting from 90Y production methods. The 90Y in SIR-Spheres and Zevalin are produced from a 90Sr/90Y generator, which leaves measurable quantities of 90Sr in the final product. TheraSphere 90Y is produced in a nuclear reactor which results in a large number of impurities, most notably 88Y and 91Y. Product information sheets reference these impurities with specific limits given. These limits represent a tiny fraction of the total product activity, and in the case of TheraSphere and SIR-Spheres gamma-emitting impurities, this has been verified in the literature. An analysis of 90Sr impurities in SIR-Spheres and Zevalin is presented in this paper. Impurity quantities were found to be within the vendors’ documented limits.

Life-threatening hyperkalemia following zoledronic acid infusion for Paget's disease: a case report

Directory of Open Access Journals (Sweden)

Naysmith Morag

2011-08-01

Full Text Available Abstract Introduction Zoledronic acid is a highly effective treatment in Paget's disease for persistent bone pain and prevention of further progression of the disease. The commonest electrolyte abnormality is hypocalcemia. To the best of our knowledge this is the first case of hyperkalemia secondary to zoledronic acid to be published in the world literature. The commonest arrhythmia related to zoledronic acid is atrial fibrillation. Case presentation We describe the case of an 80-year-old Caucasian man, with a history of ischemic heart disease, who had an in-hospital cardiac arrest related to hyperkalemia. Increasing potassium levels were noted following his first zoledronic acid infusion for symptomatic control of bone pain secondary to Paget's disease. Our patient suffered a cardiac arrest 10 days following the zoledronic acid infusion. Our patient's biochemistry and electrocardiogram output were monitored until his death 26 days after his cardiac arrest. Our patient developed paroxysmal atrial fibrillation in the post-resuscitation period and there was persistent hyperkalemia that required prolonged treatment with calcium resonium. All other possible causes of hyperkalemia were excluded. Conclusion In our patient's case persistent hyperkalemia and life-threatening arrhythmias were associated with use of zoledronic acid. These side effects have not been reported before and the causative mechanism is far from clear as there are no obvious systemic effects of zoledronic acid. The combination of zoledronic acid with predisposing factors such as structural heart disease might account for the clinical picture we witnessed. As a result, electrolyte monitoring should be adopted early in zoledronic acid use. Further studies are required to elucidate the underlying mechanism of hyperkalemia and identify the target group of patients where zoledronic acid can be safely administered. Great caution is advised in patients with underlying heart conditions.

2008-01-01

Extramammary Paget's disease (EMPD) is a rare intraepidermal adenocarcinoma that primarily affects the anogenital region. Cases of EMPD reacting with PSA (prostate-specific antigen) have previously been associated with underlying prostate cancer. However, a recent case of EMPD in our department has...... led us to question the value of PSA as an indicator of underlying prostate cancer. Clinical and pathological data were obtained for 16 cases of EMPD. Formalin-fixed, paraffin-embedded tissue blocks from the primary skin lesions were investigated using PSA and other immunohistochemical markers. 5...... of the 16 cases of EMPD stained positive for PSA (2 women and 3 men). However, no reactivity was seen for the prostatic marker P501S. Three of the five patients had been diagnosed with internal malignant disease-two with prostate cancer, stage 1.

Extramammary Paget's disease (EMPD) is a rare cutaneous neoplasm that is thought to represent intraepithelial adenocarcinoma developing in an area rich in apocrine glands. Magnetic resonance imaging (MRI) findings for this disease are not well established. We report three cases of pathologically confirmed EMPD in which MRI was performed before surgery. The lesions were widespread in the epidermis and the dermis. Lesions were sharply well enhanced on gadolinium-enhanced T1-weighted imaging and appeared hyperintense on diffusion-weighted imaging in all cases. Areas with enhancement in depth corresponded well with the pathological lesion. In addition, different malignant legions were found on the same images from MRI in two cases, indicating potential associations with other malignancies. We describe the MRI findings and their pathological correlation. MRI could be useful for preoperative evaluation of disease spread and detection of associated malignancies. (orig.)

Space perception and William James's metaphysical presuppositions.

Science.gov (United States)

Farrell, Martin J

2011-05-01

William James's overtly philosophical work may be more continuous with his psychological work than is sometimes thought. His Essays in Radical Empiricism can be understood as an explicit statement of the absolute presupposition that formed the basis of Jamesian psychology: that direct experience is primary and has to be taken at face value. An examination of James's theory of space perception suggests that, even in his early work, he presupposed the primacy of direct experience, and that later changes in his account of space perception can be understood as making his view more consistent with this presupposition. In his earlier view of space perception, James argued that sensations were directly experienced as spatial, though he accepted that spatial relations between sensations may be constructed by higher order thought. In his later view, however, James argued that spatial relations were just as directly experienced as sensations. The work of T. H. Green may have prompted James to recognize the full consequence of his ideas and to realize that taking experience at face value required that spatial relations be thought of as intrinsic to experience rather than the result of intellectual construction.

C. elegans SIRT6/7 homolog SIR-2.4 promotes DAF-16 relocalization and function during stress.

FoxO transcription factors and sirtuin family deacetylases regulate diverse biological processes, including stress responses and longevity. Here we show that the Caenorhabditis elegans sirtuin SIR-2.4--homolog of mammalian SIRT6 and SIRT7 proteins--promotes DAF-16-dependent transcription and stress-induced DAF-16 nuclear localization. SIR-2.4 is required for resistance to multiple stressors: heat shock, oxidative insult, and proteotoxicity. By contrast, SIR-2.4 is largely dispensable for DAF-16 nuclear localization and function in response to reduced insulin/IGF-1-like signaling. Although acetylation is known to regulate localization and activity of mammalian FoxO proteins, this modification has not been previously described on DAF-16. We find that DAF-16 is hyperacetylated in sir-2.4 mutants. Conversely, DAF-16 is acetylated by the acetyltransferase CBP-1, and DAF-16 is hypoacetylated and constitutively nuclear in response to cbp-1 inhibition. Surprisingly, a SIR-2.4 catalytic mutant efficiently rescues the DAF-16 localization defect in sir-2.4 null animals. Acetylation of DAF-16 by CBP-1 in vitro is inhibited by either wild-type or mutant SIR-2.4, suggesting that SIR-2.4 regulates DAF-16 acetylation indirectly, by preventing CBP-1-mediated acetylation under stress conditions. Taken together, our results identify SIR-2.4 as a critical regulator of DAF-16 specifically in the context of stress responses. Furthermore, they reveal a novel role for acetylation, modulated by the antagonistic activities of CBP-1 and SIR-2.4, in modulating DAF-16 localization and function.

SirT1—A Sensor for Monitoring Self-Renewal and Aging Process in Retinal Stem Cells

Directory of Open Access Journals (Sweden)

2010-06-01

Full Text Available Retinal stem cells bear potency of proliferation, self-renewal, and differentiation into many retinal cells. Utilizing appropriate sensors one can effectively detect the self-renewal and aging process abilities. Silencing information regulator (SirT1, a member of the sirtuin family, is a NAD-dependent histone deacetylase and an essential mediator for longevity in normal cells by calorie restriction. We firstly investigate the SirT1 mRNA expression in retinal stem cells from rats and 19 human eyes of different ages. Results revealed that SirT1 expression was significantly decreased in in vivo aged eyes, associated with poor self-renewal abilities. Additionally, SirT1 mRNA levels were dose-dependently increased in resveratrol- treated retinal stem cells. The expression of SirT1 on oxidative stress-induced damage was significantly decreased, negatively correlated with the level of intracellular reactive oxygen species production. Treatment with resveratrol could effectively further reduce oxidative stress induced by H2O2 treatment in retinal stem cells. Importantly, the anti-oxidant effects of resveratrol in H2O2-treated retinal stem cells were significantly abolished by knockdown of SirT1 expression (sh-SirT1. SirT1 expression provides a feasible sensor in assessing self-renewal and aging process in retinal stem cells. Resveratrol can prevent reactive oxygen species-induced damages via increased retinal SirT1 expression.

"Cet obscur objet du Désir"

Reto Melchior

1996-09-01

Full Text Available Luis Bunuel’s last film is based on Pierre Louÿs’ La Femme et le Pantin. This now forgotten bestseller, published in 1898, is drawn from Goya s painting El Pelele, in which four women are playing with a male puppet. In Pierre Louÿs’ novel this scene is inverted so that one woman with two faces plays with four men. In Cet Obscur Objet du Désir this “femme fatale” is interpreted by two actresses. The concentric structure of the film puts focus on a scene of being excluded from knowing. The technique of continually interrupting the flash-back sequences frustrates the audience because of its exclusion from the “real” course of events and gives rise to doubts whether the male protagonist tells the truth about his love-affair or whether he satisfies the curiosity of the audience by telling them Pierre Louÿs’ novel as his own story. This ambiguous art of narration mirrors Bunuel’s claim that the main topic of Cet Obscur Objet du Désir is frustration.

Full Text Available Three questions form the basis of this analysis of the relationship of the Epistle of James to the traditions of wisdom, eschatology and apocalypticism. What kind of traditions are involved in James? What is the world view of James? What audience or community is presupposed by this writing? Foremost is the connection that James demonstrates to the wisdom tradition evident in the Old Testament and extratestamental literature. In particular two types of wisdom tradition are noted in James: practical wisdom advice as expressed in short sayings, wisdom instructions and admonitions and reflection on the nature of wisdom (1:5-8; 2:1-7; and 3:13-18 as coming from God. Finally, the question of how much apocalyptic symbolism is evident in the eschatological world view of the epistle is addressed.

Vulvar intraepithelial neoplasia (VIN) and vulvar Paget disease are managed with either vulvectomy, destructive treatments (laser, antimitotic drugs) or immunostimulants. All these options are associated with functional complications. The purpose of this study was to evaluate the surgical technique consisting of skinning vulvectomy with split-thickness skin graft, and its effect on overall quality of life and sexual function. A retrospective study was conducted on thirteen patients who underwent skinning vulvectomy with split-thickness skin graft between 1999 and 2009. Overall quality of life and sexual function were assessed with the Medical Outcome Study Short Form 36 (MOS SF-36) and Female Sexual Function Index (FSFI), respectively. The median age of patients was 54 (range: 33-77) years. Three patients had Paget disease and 10 patients had VIN lesions. The excision margins were clear in 46% of cases. The incidence of occult cancer was 31%. The mean follow-up period was 77 (±35) months. Four patients experienced a relapse of their intraepithelial disease. The mean disease-free survival was 58 (±44) months. There was no significant difference in MOS SF-36 scores between the study population and the general population. The patients assessed with the FSFI regained normal sexual function after the surgical procedure. Skinning vulvectomy with split-thickness skin graft is a feasible technique yielding good results in terms of quality of life and sexual function. It enables occult cancer to be diagnosed in patients with VIN or Paget disease. Copyright © 2013 Elsevier Ltd. All rights reserved.

Paget-Schroetter syndrome (PSS) in the context of upper extremity deep venous thrombosis (DVT) is an uncommon but potentially very serious condition affecting young, healthy adults, in which secondary post-thrombotic syndrome (PTS) can be a complication with major implications. The best treatment option remains controversial, with current guidelines recommending anticoagulation for at least 3 months. However, an incidence of PTS of approximately 50% after 6 months, 30% after 1 year and 25% after 2 years has been found using this therapeutic approach. Consequently, specialized units recommend local thrombolysis and early decompressive surgery. We describe a series of eight cases treated in this way. None of the patients showed signs of complications, and an early return to regular activities with no PTS was observed in 90% of cases. Copyright © 2014 SEPAR. Published by Elsevier Espana.

Full Text Available American psychologist and philosopher William James devoted the entirety of his career to exploring the nature of volition, as expressed by such phenomena as will, attention, and belief. As part of that endeavor, James's unorthodox scientific pursuits, from his experiments with nitrous oxide and hallucinogenic drugs to his investigation of spiritualist mediums, represent his attempt to address the "hard problems" of consciousness for which his training in brain physiology and experimental psychology could not entirely account. As a student, James's reading in chemistry and physics had sparked his interest in the concepts of energy and force, terms that he later deployed in his writing about consciousness and in his arguments against philosophical monism and scientific materialism, as he developed his radically empiricist ideas privileging discontinuity and plurality. Despite James's long campaign against scientific materialism, he was, however, convinced of the existence of a naturalistic explanation for the more "wayward and fitful" aspects of mind, including transcendent experiences associated with hysteria, genius, and religious ecstasy. In this paper, I examine aspects of James's thought that are still important for contemporary debates in psychology and neuroscience: his "transmission theory" of consciousness, his ideas on the "knowing of things together," and, finally, the related concept of "the compounding of consciousness," which postulates the theoretical possibility for individual entities within a conscious system of thought to "know" the thoughts of others within the system. Taken together, these ideas suggest that James, in spite of, or perhaps because of, his forays into metaphysics, was working toward a naturalistic understanding of consciousness, what I will term a "distributive model," based on his understanding of consciousness as an "awareness" that interacts dynamically within, and in relation to, its environment.

Environmental Assessment on the leasing of the Strategic Petroleum Reserve, St. James Terminal, St. James Parish, Louisiana

International Nuclear Information System (INIS)

1995-01-01

The US Department of Energy (DOE) proposes to lease the Strategic Petroleum Reserve's (SPR) St. James Terminal to private industry. The St. James Terminal consists of six storage tanks, a pumping station, two maine docks and ancillary facilities. DOE believes that the St. James Terminal presents an opportunity to establish a government- industry arrangement that could more effectively use this asset to serve the nations's oil distribution needs, reduce the operational cost of the SPR, and provide a source of revenue for the Government. DOE solicited interest in leasing its distribution facilities in a notice published March 16, 1994. In response, industry has expressed interest in leasing the St. James Terminal, as well as several DOE pipelines, to enhance the operation of its own facilities or to avoid having to construct new ones. Under such a lease, industry use would be subordinate to DOE use in the event of a national energy emergency. This Environmental Assessment describes the proposed leasing operation, its alternatives, and potential environmental impacts. Based on this analyses, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) OF 1969 and has issued the Finding of No Significant Impact (FONSI)

The point spectrometer SIR-2 on Chandrayaan-1 provided radiance spectra integrated over circular footprints of 200 m diameter in the wavelength range 934-2410.8 nm in 256 channels [1]. To analyze SIR-2 reflectance spectra in their spatial context, a coregistration to Chandrayaan-1 M³ hyperspectral images [2] as well as a correction for topography and thermal emission are inevitable. The thermal and topographic correction procedure is based on the surface temperature and a digital elevation model (DEM) inferred from M³ data. The corrected reflectance spectra are then normalized to a standard illumination and viewing geometry.

CD133-expressing glioma cells play a critical role in tumor recovery after treatment and are resistant to radiotherapy. Herein, we demonstrated that glioblastoma-derived CD133-positive cells (GBM-CD133 + ) are capable of self-renewal and express high levels of embryonic stem cell genes and SirT1 compared to GBM-CD133 - cells. To evaluate the role of SirT1 in GBM-CD133 + , we used a lentiviral vector expressing shRNA to knock-down SirT1 expression (sh-SirT1) in GBM-CD133 + . Silencing of SirT1 significantly enhanced the sensitivity of GBM-CD133 + to radiation and increased the level of radiation-mediated apoptosis. Importantly, knock-down of SirT1 increased the effectiveness of radiotherapy in the inhibition of tumor growth in nude mice transplanted with GBM-CD133 + . Kaplan-Meier survival analysis indicated that the mean survival rate of GBM-CD133 + mice treated with radiotherapy was significantly improved by Sh-SirT1 as well. In sum, these results suggest that SirT1 is a potential target for increasing the sensitivity of GBM and glioblastoma-associated cancer stem cells to radiotherapy.

Full Text Available Differentiating sepsis from other noninfectious causes of systemic inflammation is often difficult in the elderly. The aim of this study was to evaluate the ability of C-reactive protein (CRP, Erythrocyte Sedimentation Rate (ESR, procalcitonin (PCT, and Interleukin-6 (IL-6 to identify elderly patients with sepsis. In this single center prospective observational study, we included all consecutive elderly patients admitted with suspected sepsis and systemic inflammatory response syndrome (SIRS in an emergency department. Blood samples for measuring CRP, PCT, IL-6, ESR and white blood cells (WBC count were taken at first day of admission. Sensitivity, specificity, positive and negative predictive values were calculated for each inflammatory markers being studied. A total of 150 elderly patients aged 65 and older, 50 with sepsis and 50 with SIRS, and fifty individuals in a normal health status were included. CRP exhibited the greatest sensitivity (98% and negative predictive value (98.6% and performed best in differentiating patients with sepsis from those with SIRS. In a receiver operating characteristic curve analysis, IL-6 performed best in distinguishing between SIRS and the control group (AUC 0.75, 95% CI. On the other hand, both CRP and ESR appeared to be a more accurate diagnostic parameter for differentiating sepsis from SIRS among elderly patients.

2012-12-01

Full Text Available Sir2, an evolutionarily conserved NAD+-dependent deacetylase, has been implicated as a key factor in mediating organismal life span. However, recent contradictory findings have brought into question the role of Sir2 and its orthologs in regulating organismal longevity. In this study, we report that Drosophila Sir2 (dSir2 in the adult fat body regulates longevity in a diet-dependent manner. We used inducible Gal4 drivers to knock down and overexpress dSir2 in a tissue-specific manner. A diet-dependent life span phenotype of dSir2 perturbations (both knockdown and overexpression in the fat body, but not muscles, negates the effects of background genetic mutations. In addition to providing clarity to the field, our study contrasts the ability of dSir2 in two metabolic tissues to affect longevity. We also show that dSir2 knockdown abrogates fat-body dFOXO-dependent life span extension. This report highlights the importance of the interplay between genetic factors and dietary inputs in determining organismal life spans.

Social and environmental impacts of the James Bay hydroelectric project

The book, which is an analysis and not an advocacy, examines the anatomy of the controversy that has swirled around the James Bay project - the La Grande and Great Whale projects combined - from the 1970s to the 1990s, and seeks, in the process, to determine whether there are lessons that can be learned from such an analysis that are applicable to other cases as well as to James Bay itself. The contributors are interested, at one and the same time, in finding ways to integrate the knowledge of natural scientists and social scientists to deepen the understanding of human/environment relations and to link science and policy to encourage a productive dialogue between practitioners and scholars in this increasingly important area of inquiry. The contributor's papers include the following: introduction to the issues; hydroelectric power development at James Bay: establishing a frame of reference; James Bay: environmental considerations for building large hydroelectric dams and reservoirs in Quebec; elevated mercury in fish as a result of the James Bay hydroelectric power development: perception and reality; the Cree people of James Bay: assessing the social impacts of hydroelectric dams and reservoirs; culture, social change, and Cree opposition to the James Bay hydroelectric development; and the impact of James Bay hydroelectric development on the art and craft of the James Bay Cree. The authors of the volume have attempted to stand back and examine just a few of these issues from the perspective of a variety of disciplines, and their purpose is to inform and stimulate thoughtful consideration by providing an overall perspective that might might serve to broaden the context in which specific issues can be debated. refs., 3 tabs., 5 figs

Comparison of QSOFA score and SIRS criteria as screening mechanisms for emergency department sepsis.

2017-11-01

The Quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA) score has been shown to accurately predict mortality in septic patients and is part of recently proposed diagnostic criteria for sepsis. We sought to ascertain the sensitive of the score in diagnosing sepsis, as well as the diagnostic timeliness of the score when compared to traditional systemic inflammatory response syndrome (SIRS) criteria in a population of emergency department (ED) patients treated in the ED, admitted, and subsequently discharged with a diagnosis of sepsis. Electronic health records of 200 patients who were treated for suspected sepsis in our ED and ultimately discharged from our hospital with a diagnosis of sepsis were randomly selected for review from a population of adult ED patients (N=1880). Data extracted included the presence of SIRS criteria and the qSOFA score as well as time required to meet said criteria. In this cohort, 94.5% met SIRS criteria while in the ED whereas only 58.3% met qSOFA. The mean time from arrival to SIRS documentation was 47.1min (95% CI: 36.5-57.8) compared to 84.0min (95% CI: 62.2-105.8) for qSOFA. The median ED "door" to positive SIRS criteria was 12min and 29min for qSOFA. Although qSOFA may be valuable in predicting sepsis-related mortality, it performed poorly as a screening tool for identifying sepsis in the ED. As the time to meet qSOFA criteria was significantly longer than for SIRS, relying on qSOFA alone may delay initiation of evidence-based interventions known to improve sepsis-related outcomes.

SirT1 confers hypoxia-induced radioresistance via the modulation of c-Myc stabilization on hepatoma cells

International Nuclear Information System (INIS)

Xie Yuexia; Zhang Jianghong; Shao Chunlin; Xu Yanwu

2012-01-01

Intratumoral hypoxia is an important contributory factor to tumor cell resistance to radiotherapy. SirT1, a nicotinamide adenine dinucleotide (NAD + )-dependent histone/protein deacetylase, has been linked to the decrease of radiation-induced DNA damage and seems to be critical for cancer therapy. The purpose of this study was to investigate the role of SirT1 in hypoxia-induced radiation response on hepatoma cells. It was found that the administration with resveratrol, a putative SirT1 activator, enhanced the resistance of HepG2 cells against radiation-induced DNA damage of MN formation under hypoxia condition; while nicotinamide, a well-known SirT1 inhibitor, sensitized this radiation damage. Nevertheless, pretreatment of cells with 10058-F4, a specific inhibitor of c-Myc, almost eliminated the nicotinamide-induced radiosensitive effect. Further studies revealed that resveratrol inhibited c-Myc protein accumulation via up-regulation of SirT1 expression and deacetylase activity, and this loss of c-Myc protein was abolished by inhibiting its degradation in the presence of MG132, a potent inhibitor of proteasome. In contrast, nicotinamide attenuated c-Myc protein degradation induced by radiation under hypoxia through inhibition of SirT1 deacetylase activity. Our findings suggest that SirT1 could serve as a novel potent target of radiation-induced DNA damage and thus as a potential strategy to advance the efficiency of radiation therapy in hepatoma entities.

Viral marketing is a marketing strategy utilizes social media to spread information about a product or services provided. It is the most powerful way to share information in a short amount of time. The objective of this study is to investigate the dynamic of viral marketing within a time duration in the point of view of mathematics. This study used the epidemiological model known as Susceptible-Infected-Recovered (SIR). The model consists of a system of three differential equations with three state variables namely susceptible (S), infected (I) and recovered (R). It considers a case of SIR model with demography. Numerical experiments have been performed. The results show that viral marketing reaches its peak within two days. The online messages shared will become higher if the initial number of the infected individual has been increased.

Sir Karl Popper and his philosophy of physics

Science.gov (United States)

Jammer, Max

1991-12-01

The eminent mathematical physicist Sir Hermann Bondi once said: “There is no more to science than its method, and there is no more to its method than Popper has said.” Indeed, many regard Sir Karl Raimund Popper the greatest philosopher of science in our generation. Much of what Popper “has said” refers to physics, but physicists, generally speaking, have little knowledge of what he has said. True, Popper's philosophy of science and, in particular, his realistic interpretation of quantum mechanics deviates considerably from the generally accepted doctrine. But as Popper, rightly I think, points out, it is precisely the proliferation of divergent theories which promotes the growth of scientific knowledge; it would be a danger for physics if physicists were dogmatically tied to a single theory or would not test their theory against alternatives. It is for this purpose that, on the occasion of the nonagenarian celebration of Popper's birthday, the present essay has been written.

Highlights: • γ-Irradiation induced bystander effects between hepatoma cells and hepatocyte cells. • SirT1 played a protective role in regulating this bystander effect. • SirT1 contributed to the protective effects via elimination the accumulation of ROS. • The activity of c-Myc is critical for maintaining the protective role of SirT1. - Abstract: Radiation-induced bystander effect (RIBE) has important implications for secondary cancer risk assessment during cancer radiotherapy, but the bystander signaling processes, especially under hypoxic condition, are still largely unclear. The present study found that micronuclei (MN) formation could be induced in the non-irradiated HL-7702 hepatocyte cells after being treated with the conditioned medium from irradiated hepatoma HepG2 and SK-Hep-1 cells under either normoxia or hypoxia. This bystander response was dramatically diminished or enhanced when the SirT1 gene of irradiated hepatoma cells was overexpressed or knocked down, respectively, especially under hypoxia. Meanwhile, SirT1 knockdown promoted transcriptional activity for c-Myc and facilitated ROS accumulation. But both of the increased bystander responses and ROS generation due to SirT1-knockdown were almost completely suppressed by c-Myc interference. Moreover, ROS scavenger effectively abolished the RIBE triggered by irradiated hepatoma cells even with SirT1 depletion. These findings provide new insights that SirT1 has a profound role in regulating RIBE where a c-Myc-dependent release of ROS may be involved

Paget Schroetter syndrome, or effort thrombosis of the axillosubclavian venous system, is distinct from other forms of upper limb deep vein thrombosis. It occurs in younger patients and often is secondary to competitive sport, music, or strenuous occupation. If untreated, there is a higher incidence of disabling venous hypertension than was previously appreciated. Anticoagulation alone or in combination with thrombolysis leads to a high rate of rethrombosis. We have established a multidisciplinary protocol over 15 years, based on careful patient selection and a combination of lysis, decompressive surgery, and postoperative percutaneous venoplasty. During the past 10 years, a total of 232 decompression procedures have been performed. This article reviews the literature and presents the Exeter Protocol along with practical recommendations for management.

Stability analysis of the Euler discretization for SIR epidemic model

International Nuclear Information System (INIS)

Suryanto, Agus

2014-01-01

In this paper we consider a discrete SIR epidemic model obtained by the Euler method. For that discrete model, existence of disease free equilibrium and endemic equilibrium is established. Sufficient conditions on the local asymptotical stability of both disease free equilibrium and endemic equilibrium are also derived. It is found that the local asymptotical stability of the existing equilibrium is achieved only for a small time step size h. If h is further increased and passes the critical value, then both equilibriums will lose their stability. Our numerical simulations show that a complex dynamical behavior such as bifurcation or chaos phenomenon will appear for relatively large h. Both analytical and numerical results show that the discrete SIR model has a richer dynamical behavior than its continuous counterpart

Full Text Available Le désir est au cœur des interactions complexes entre le développement et la religion. Cet article examine ses différentes expressions, comme étant une des préoccupations fondamentales de nombreuses religions, qui motivent à la fois le développement et les alternatives au développement. Au SriLanka, face au changement social, la forme néolibérale et mondialisée du développement est comprise et réinterprétée à travers des idiomes et des formations locales du désir. L’économie néolibérale cultive le désir et mène à un accroissement présumé de la présence des preta (fantômes affamés et avides qui se manifestent parfois au moment de la mort d’une personne. Les fantômes affamés, en tant que formations fétichisées du désir, trouvent un écho chez les consommateurs et les entrepreneurs, qui montrent unappétit insatiable vis-à-vis d’une richesse matérielle en constante croissance. Ainsi, l’apaisement ritualisé des fantômes affamés et le militantisme social de groupes tels que le Movement for National Land and Agricultural Reform (MONLAR sont clairement liés par leur préoccupation mutuelle face à l’insécurité existentielle des êtres humains et non humains, causée par un désir excessif et déséquilibré. L’action rituelle et le militantisme social divergent toutefois dans la formulation explicite de leurs préoccupations spécifiques concernant le désir. Le rituel matérialise et condense l’angoisse liée au désir, alors que le militantisme social décrit la fétichisation du désir en termes économiques, politiques et scientifiques plus abstraits.

We compared the biochemical effects and safety of pamidronate (30 mg a day for 3 consecutive days) versus clodronate (300 mg a day for 3 consecutive days) via intravenous infusion in 14 patients with Paget's disease of bone (PDB). Both drugs induced a decrease in serum alkaline phosphatase levels as well as the elimination of hydroxyproline from urine, an effect most marked in the group treated with pamidronate. The response was maintained for 6 months after the infusion in the majority of the patients. No relevant side effects were found, except post-infusion febricula and in one patient, self-limiting thrombopenia 6 months after the infusion. We conclude that the intravenous infusion of either of the two drugs may constitute a safe and effective alternative for treatment of PDB with marked biochemical activity or resistant to conventional therapy.

Hoarding symptoms among psychiatric outpatients: confirmatory factor analysis and psychometric properties of the Saving Inventory – Revised (SI-R

Directory of Open Access Journals (Sweden)

Siau Pheng Lee

2016-10-01

Full Text Available Abstract Background The growing interest in problematic hoarding as an independent clinical condition has led to the development of the Saving Inventory-Revised (SI-R to assess hoarding phenomenology. The SI-R is one of the most widely used instruments to measure hoarding symptoms; however, it lacks validation in non-Western samples. Methods The current study examined the construct, convergent, and discriminant validity of the SI-R among 500 outpatients at a psychiatric hospital in Singapore. The three-factor structure solution of the SI-R was fitted in a confirmatory factor analysis. Results The final model achieved mediocre fit (χ2 = 1026.02, df = 186; RMSEA = 0.095, SRMR = 0.06; CFI = 0.86; NNFI = 0.85. Two reverse-coded items (items 2 and 4 were removed due to insufficient factor loadings, resulting in the modified 21-item SI-R (SIR-21. Our findings indicate the need to further examine the construct validity of the SI-R, particularly in non-Western samples. Nonetheless, correlations with other hoarding-related constructs, such as anxiety (Beck Anxiety Inventory and depression (Beck Depression Inventory-II, supported the convergent and discriminant validity of the SIR-21 in our sample. Conclusions Findings in our current majority Chinese sample were consistent with previous observations from other Chinese samples. Implications were discussed from a cross-cultural perspective, such as cultural emphasis on saving for future use and overlap between the concepts of discarding and acquiring in Chinese samples. Future studies should also examine differences among other ethnic groups (e.g., Malay, Indian.

Sustainable development in the Hudson Bay/James Bay bioregion

International Nuclear Information System (INIS)

Anon.

1991-01-01

An overview is presented of projects planned for the James Bay/Hudson Bay region, and the expected environmental impacts of these projects. The watershed of James Bay and Hudson Bay covers well over one third of Canada, from southern Alberta to central Ontario to Baffin Island, as well as parts of north Dakota and Minnesota in the U.S.A. Hydroelectric power developments that change the timing and rate of flow of fresh water may cause changes in the nature and duration of ice cover, habitats of marine mammals, fish and migratory birds, currents into and out of Hudson Bay/James Bay, seasonal and annual loads of sediments and nutrients to marine ecosystems, and anadromous fish populations. Hydroelectric projects are proposed for the region by Quebec, Ontario and Manitoba. In January 1992, the Canadian Arctic Resources Committee (CARC), the Environmental Committee of Sanikuluaq, and the Rawson Academy of Arctic Science will launch the Hudson Bay/James Bay Bioregion Program, an independent initiative to apply an ecosystem approach to the region. Two main objectives are to provide a comprehensive assessment of the cumulative impacts of human activities on the marine and freshwater ecosystems of the Hudson Bay/James Bay bioregion, and to foster sustainable development by examining and proposing cooperative processes for decision making among governments, developers, aboriginal peoples and other stakeholders. 1 fig

Full Text Available La enfermedad de Paget es un trastorno crónico del remodelado óseo, caracterizado por un aumento de la resorción ósea producido por osteoclastos atípicos, seguido por un incremento acelerado de la formación ósea, lo que resulta en la formación de hueso en mosaico desorganizado. Un excelente marcador bioquímico para orientar el diagnóstico y seguimiento es la fosfatasa alcalina (FAL. Se presenta el caso de un paciente de 90 años, de sexo masculino, con diagnóstico de enfermedad de Paget. Se inicia tratamiento con pamidronato vía oral con respuesta parcial, por lo que se rota a pamidronato endovenoso. Disminuyen el dolor y la concentración plasmática de FAL, persistiendo con centellograma óseo patológico. Luego de varios años de tratamiento, con adecuado aporte de calcio y vitamina D, comienza nuevamente con dolor y valores elevados de FAL. Se decide iniciar tratamiento con ácido zoledrónico endovenoso 4 mg, única aplicación, obteniéndose remisión clínica y bioquímica desde hace cuatro años y mejoría de la imagen centellográfica. Este informe refiere la buena respuesta, sostenida en el tiempo, al tratamiento con única dosis de ácido zoledrónico en un paciente que presentó resistencia al pamidronato.

Fkh1 and Fkh2 associate with Sir2 to control CLB2 transcription under normal and oxidative stress conditions

2013-07-01

Full Text Available The Forkhead box family of transcription factors is evolutionary conserved from yeast to higher eukaryotes and its members are involved in many physiological processes including metabolism, DNA repair, cell cycle, stress resistance, apoptosis and aging. In budding yeast, four Forkhead transcription factors were identified, namely Fkh1, Fkh2, Fhl1, and Hcm1, which are implicated in chromatin silencing, cell cycle regulation and stress response. These factors impinge transcriptional regulation during cell cycle progression, and histone deacetylases play an essential role in this process, e.g. the nuclear localisation of Hcm1 depends on Sir2 activity, whereas Sin3/Rpd3 silence cell cycle specific gene transcription in G2/M phase. However, a direct involvement of Sir2 in Fkh1/Fkh2-dependent regulation of target genes is at present unknown. Here, we show that Fkh1 and Fkh2 associate with Sir2 in G1 and M phase, and that Fkh1/Fkh2-mediated activation of reporter genes is antagonized by Sir2. We further report that Sir2 overexpression strongly affects cell growth in an Fkh1/Fkh2-dependent manner. In addition, Sir2 regulates the expression of the mitotic cyclin Clb2 through Fkh1/Fkh2-mediated binding to the CLB2 promoter in G1 and M phase. We finally demonstrate that Sir2 is also enriched at the CLB2 promoter under stress conditions, and that the nuclear localization of Sir2 is dependent on Fkh1 and Fkh2. Taken together, our results show a functional interplay between Fkh1/Fkh2 and Sir2 suggesting a novel mechanism of cell cycle repression. Thus, in budding yeast, not only the regulation of G2/M gene expression but also the protective response against stress could be directly coordinated by Fkh1 and Fkh2.

Bressette, W. E.

1978-01-01

A photographic flight was made over the James River on May 17, 1977. The data show that, in general, James River water has very high sunlight reflectance. In the Bailey Bay area this reflectance is drastically reduced. Also shown is a technique for normalizing off-axis variations in radiance film exposure from camera falloff and uneven sunlight conditions to the nadir value. After data normalization, a spectral analysis is performed that identifies Bailey Creek water in James River water. The spectral results when compared with laboratory spectrometer data indicate that reflectance from James River water is dominated by suspended matter, while the substance most likely responsible for reduced reflectance in Bailey Creek water is dissolved organic carbon.

Hayns, M.

1989-01-01

A joint USA-UK venture has been initiated to design a small nuclear reactor which offers low capital cost, greater flexibility and a potentially lower environmental impact. Called Safe Integral Reactor (SIR), the lead unit could be built in the United Kingdom Atomic Energy Authority's (UKAEA's) Winfrith site if the design is accepted by the UK Nuclear Installations Inspectorate (NII). This article describes the 320 MWe reactor unit that is the basis of the design being developed. (author)

Analysis of data acquired by Shuttle Imaging Radar SIR-A and Landsat Thematic Mapper over Baldwin County, Alabama

Science.gov (United States)

Wu, S.-T.

1985-01-01

Seasonally compatible data collected by SIR-A and by Landsat 4 TM over the lower coastal plain in Alabama were coregistered, forming a SIR-A/TM multichannel data set with 30 m x 30 m pixel size. Spectral signature plots and histogram analysis of the data were used to observe data characteristics. Radar returns from pine forest classes correlated highly with the tree ages, suggesting the potential utility of microwave remote sensing for forest biomass estimation. As compared with the TM-only data set, the use of SIR-A/TM data set improved classification accuracy of the seven land cover types studied. In addition, the SIR-A/TM classified data support previous finding by Engheta and Elachi (1982) that microwave data appear to be correlated with differing bottomland hardwood forest vegetation as associated with varying water regimens (i.e., wet versus dry).

Early recognition of severe form of acute pancreatitis is important because these patients need more agressive diagnostic and therapeutical approach an can develope systemic complications such as: sepsis, coagulopathy, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), Multiple Organ Dysfunction Syndrome (MODS), Multiple Organ Failure (MOF). To determine role of the combination of Systemic Inflammatory Response Syndrome (SIRS) score and serum Interleukin-6 (IL-6) level on admission as predictor of illness severity and outcome of Severe Acute Pancreatitis (SAP). We evaluated 234 patients with first onset of SAP appears in last twenty four hours. A total of 77 (33%) patients died. SIRS score and serum IL-6 concentration were measured in first hour after admission. In 105 patients with SIRS score 3 and higher, initial measured IL-6 levels were significantly higher than in the group of remaining 129 patients (72 +/- 67 pg/mL, vs 18 +/- 15 pg/mL). All nonsurvivals were in the first group, with SIRS score 3 and 4 and initial IL-6 concentration 113 +/- 27 pg/mL. The values of C-reactive Protein (CRP) measured after 48h, Acute Physiology and Chronic Health Evaluation (APACHE II) score on admission and Ranson score showed the similar correlation, but serum amylase level did not correlate significantly with Ranson score, IL-6 concentration and APACHE II score. The combination of SIRS score on admission and IL-6 serum concentration can be early, predictor of illness severity and outcome in SAP.

Yeast Tdh3 (glyceraldehyde 3-phosphate dehydrogenase is a Sir2-interacting factor that regulates transcriptional silencing and rDNA recombination.

Directory of Open Access Journals (Sweden)

Alison E Ringel

Full Text Available Sir2 is an NAD(+-dependent histone deacetylase required to mediate transcriptional silencing and suppress rDNA recombination in budding yeast. We previously identified Tdh3, a glyceraldehyde 3-phosphate dehydrogenase (GAPDH, as a high expression suppressor of the lethality caused by Sir2 overexpression in yeast cells. Here we show that Tdh3 interacts with Sir2, localizes to silent chromatin in a Sir2-dependent manner, and promotes normal silencing at the telomere and rDNA. Characterization of specific TDH3 alleles suggests that Tdh3's influence on silencing requires nuclear localization but does not correlate with its catalytic activity. Interestingly, a genetic assay suggests that Tdh3, an NAD(+-binding protein, influences nuclear NAD(+ levels; we speculate that Tdh3 links nuclear Sir2 with NAD(+ from the cytoplasm.

William James and the Heidelberg fiasco.

Science.gov (United States)

Gundlach, Horst

2018-02-01

Urged on by his father to become a physician instead of a painter, William James pursued 3 evasion stratagems. First, to avoid becoming a practitioner, he declared that he wanted to specialize in physiology. Based upon this premise, he left for Germany in the spring of 1867. The second step was giving up general physiology and announcing that he would specialize in the nervous system and psychology. Based upon this premise, he declared that he would go to Heidelberg and study with Helmholtz and Wundt. However, he then deferred going there. When, at last, he was urged by an influential friend of his father's to accompany him to Heidelberg, he employed his default stratagem: He simply fled. He returned home after 3 terms in Europe without enrolling at a single university. There is no evidence that he had learned anything there about psychology or experimental psychology, except, possibly, by reading books. James's "Heidelberg fiasco" was the apogee of his evasion of his father's directive. A dense fog of misinformation surrounds his stay in Heidelberg to this day. By analyzing circumstances and context, this article examines the fiasco and places it in the pattern of his behavior during his stay in Europe. Nevertheless, experiencing this fiasco potentially shaped James's ambivalent attitude toward experimental psychology on a long-term basis.

Valiquette, M.

1997-01-01

Robert Bourassa's contributions to the hydroelectric development at James Bay were acknowledged with the inauguration of a park in the ex-prime minister's name. Phase 1 of the James Bay hydroelectric project constituted the world's biggest construction site, employing more than 180,000 people from beginning to project completion. The James Bay project allowed Hydro-Quebec to gain one of the world's largest electric power utilities and to gain significant competitive edge over its competitors. The Robert Bourassa Park contains a picnic area and a visitor interpretation centre which describes the history of the project. A sequence of 5 signposts summarize the contributions that Robert Bourassa made to the megaproject which cost over $20.6 billion. The complex consists of 65 turbines which produce 15,235 megawatts of electricity. 1 fig

From James Hutton’s «Theory of the Earth» to James Lovelock’s «Gaia Hypothesis»

Directory of Open Access Journals (Sweden)

García Cruz, Cándido Manuel

2007-06-01

Full Text Available In order to understand to what extent James Hutton (1726-1797 can in fact be considered as one of the first forerunners of the Gaia Hypothesis, his Theory of the Earth is analysed into context
of the three basic traditions of science: organismic, magical and mechanistic. In the some authors’ opinion, Hutton should have written in his theory the Earth was a superorganism and its proper
study should be by physiology. These supposed assertions are merely a misinterpretation of the Huttonian philosophy, since were never held by this author. Hutton has nevertheless an holistic view which is closer to the Alfred N. Whitehead's organic mechanicism than the James Lovelock's
Gaia Hypothesis, being therefore a clear forerunner of Ludwig von Bertalanffy and his System
General Theory.

Para comprender en qué medida James Hutton (1726-1797 puede ser considerado en realidad como uno de los primeros precursores de la Hipótesis Gaia, se analiza su Theory of the Earth en el contexto de las tres tradiciones básicas de la ciencia: la organísmica, la mágica y la mecanicista. Para algunos autores, Hutton habría sugerido en su teoría que la tierra era un superorganismo y que la forma más correcta para estudiarla era la fisiología. Estas supuestas afirmaciones son simplemente una interpretación errónea del pensamiento huttoniano, puesto que este autor nunca las hizo. Sin embargo, Hutton posee de hecho una visión holística que está más próxima al mecanicismo orgánico de Alfred N. Whitehead que a la Hipótesis Gaia de James Lovelock, siendo por tanto un claro precursor de Ludwig von Bertalanffy y su Teoría General de Sistemas.

Simulation of emotional contagion using modified SIR model: A cellular automaton approach

Science.gov (United States)

Fu, Libi; Song, Weiguo; Lv, Wei; Lo, Siuming

2014-07-01

Emotion plays an important role in the decision-making of individuals in some emergency situations. The contagion of emotion may induce either normal or abnormal consolidated crowd behavior. This paper aims to simulate the dynamics of emotional contagion among crowds by modifying the epidemiological SIR model to a cellular automaton approach. This new cellular automaton model, entitled the “CA-SIRS model”, captures the dynamic process ‘susceptible-infected-recovered-susceptible', which is based on SIRS contagion in epidemiological theory. Moreover, in this new model, the process is integrated with individual movement. The simulation results of this model show that multiple waves and dynamical stability around a mean value will appear during emotion spreading. It was found that the proportion of initial infected individuals had little influence on the final stable proportion of infected population in a given system, and that infection frequency increased with an increase in the average crowd density. Our results further suggest that individual movement accelerates the spread speed of emotion and increases the stable proportion of infected population. Furthermore, decreasing the duration of an infection and the probability of reinfection can markedly reduce the number of infected individuals. It is hoped that this study will be helpful in crowd management and evacuation organization.

Mutations in the Valosin-containing protein (VCP) gene cause a unique disorder characterized by classic Paget disease of bone (PDB), inclusion body myopathy, and frontotemporal dementia (IBMPFD). Our objective was to analyze the radiographic features of PDB associated with VCP mutations since there is a dearth of literature on the PDB component of VCP disease. Radiographic bone surveys were examined in 23 individuals with VCP mutation and compared with their unaffected relatives. Laboratory testing relevant for VCP disease was performed in all individuals. Of the 17 affected individuals with clinical manifestations of VCP disease, 16 of whom had myopathy, radiographic analysis revealed classic PDB in 11 individuals (65%). The mean age of diagnosis for myopathy was 43.8 years and for PDB was 38.1 years of age. Radiological evidence of PDB was seen in one individual (16%) amongst six clinically asymptomatic VCP mutation carriers. Alkaline phosphatase was a useful marker for diagnosing PDB in VCP disease. Radiographic findings of classic PDB are seen in 52% of individuals carrying VCP mutations at a significantly younger age than conventional PDB. Screening for PDB is warranted in at-risk individuals because of the benefit of early treatment with the new powerful bisphosphonates that hold the potential for prevention of disease. (orig.)

As part of BOREAS, the RSS-15 team conducted an investigation using SIR-C, X-SAR, and Landsat TM data for estimating total above-ground dry biomass for the SSA and NSA modeling grids and component biomass for the SSA. Relationships of backscatter to total biomass and total biomass to foliage, branch, and bole biomass were used to estimate biomass density across the landscape. The procedure involved image classification with SAR and Landsat TM data and development of simple mapping techniques using combinations of SAR channels. For the SSA, the SIR-C data used were acquired on 06-Oct-1994, and the Landsat TM data used were acquired on 02-Sep-1995. The maps of the NSA were developed from SIR-C data acquired on 13-Apr-1994. The data files are available on a CD-ROM (see document number 20010000884), or from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

Forwood, Nicholas J.; Pocock, Nicholas; Shin, Jane; Young, Andy M; Szeto, Edwin R.

2009-01-01

Full text: Background: In clinical practice the dose of Y 9 0 Sir-Spheres is calculated using a pre injection of Tc 9 9 m MAA. There is however a potential difference due to the different properties of Tc 9 9 m MAA and Y 9 0 Sir-Spheres. We assessed the concordance of lung shunting of Y 9 0 Sir-Spheres estimated using Y 9 0 Bremsstrahlung imaging, compared to shunting assessed using Tc 9 9 m MAA. Methods: 15 Patients were evaluated using 150-200 MBq of Tc 9 9 m MAA injected into the hepatic artery under angiographic guidance. Whole body images were acquired using a LEAP collimator (window of 140 kEv+/-10%). The patients were subsequently treated with Y 9 0 Sir-Spheres. After microspheres injection, whole body brehmsstrahlung images were acquired using a medium energy collimator (window settings of 75 kEv +/- 20%). Tc 9 9 m MAA images were paired with their corresponding bremsstrahlung image and lung shunting in the stu ides calculated simultaneously. Each paired dataset was analyzed by 5 operators. Results: The mean lung shunting for Tc 9 9 m MAA acquisition was 3.32% (SD 2.03) which was significantly lower than the lung shunting using the Y 9 0 acquisitions: mean 16.19% (SD of 6.43). The Pearson coefficient was r = 0.62 (p 9 0 Sir-Spheres bremsstrahlung imaging is higher than that calculated by Tc 9 9 m MAA imaging. The relationship is not sufficiently strong to use bremsstahlung imaging to retrospectively quantify the lung-to-liver shunting as indicated using Tc 9 9 M AA. Further studies are underway to assess the reliability of Tc 9 9 m MAA lung uptake calculations in determining the dose of Y 9 0 Sir-Spheres.

Milestones in plant sulfur research on sulfur-induced-resistance (SIR in Europe

Directory of Open Access Journals (Sweden)

Elke eBloem

2015-01-01

Full Text Available Until the 1970´s of the last century sulfur (S was mainly regarded as a pollutant being the main contributor of acid rain, causing forest dieback in central Europe. When Clean Air Acts came into force at the start of the 1980´s SO2 contaminations in the air were consequently reduced within the next years. S changed from an unwanted pollutant into a lacking plant nutrient in agriculture since agricultural fields were no longer fertilized indirectly by industrial pollution. S deficiency was first noticed in Brassica crops that display an especially high S demand because of its content of S-containing secondary metabolites, the glucosinolates. In Scotland, where S depositions decreased even faster than in continental Europe, an increasing disease incidence with Pyrenopeziza brassicae was observed in oilseed rape in the beginning 1990´s and the concept of sulfur-induced-resistance (SIR was developed after a relationship between the S status and the disease incidence was uncovered. Since then a lot of research was carried out to unravel the background of SIR in the metabolism of agricultural crops and to identify metabolites, enzymes and reactions, which are potentially activated by the S metabolism to combat fungal pathogens. The S status of the crop is affecting many different plant features such as color and scent of flowers, pigments in leaves, metabolite concentrations and the release of gaseous S compounds which are directly influencing the desirability of a crop for a variety of different organisms from microorganisms, over insects and slugs to the point of grazing animals.The present paper is an attempt to sum up the knowledge about the effect of the S nutritional status of agricultural crops on parameters that are directly related to their health status and by this to SIR. Milestones in SIR research are compiled, open questions are addressed and future projections were developed.

2005-01-01

Sir Geoffrey Keynes (1887 - 1982), was a pioneer in the surgery of breast cancer and thymic deseases, n.b. in patients suffering from myastenia gravis. He strongly disapproved of the longstanding dogma of so called radical mastectomy in breast cancer, and advocated a more limited surgical approach, followed by radiation therapy. This was done more than fifty years before breastconserving surgery has become the therapy of choice and against considerable opposition from the surgical establishment of his days. He also became a pioneer in the surgical treatment of myastenia gravis by thymectomy, at a time when there was no real understanding of the pathophysiology of the disease and when considerable controversy existed as to the importance or non importance of concomitant tumour formation in the thymus. Besides being a busy surgeon Sir Geoffrey was a medical historian, writing the biography of among others William Harvey, a bibliographer with a special interest in the poet and artist William Blake and a bibliophil with a large book collection of great value to medical history.

Field observations explain the radar responses of three types of radar rivers: RR-1, RR-2, and RR-3. A generalized model of the radar rivers, based on field studies and regional geologic relations, shows apparent changes in river regimen since the large valleys were established during the late Paleogene-early Neogene eras. SIR-based mapping of these paleodrainages, although incomplete, reveals missing links in an area once thought to be devoid of master streams.

This paper describes and demonstrates a method for relative risk estimation which is based on the stochastic SIR-SI vector-borne infectious disease transmission model specifically for Dengue and Chikungunya diseases in Malaysia. Firstly, the common compartmental model for vector-borne infectious disease transmission called the SIR-SI model (susceptible-infective-recovered for human populations; susceptible-infective for vector populations) is presented. This is followed by the explanations on the stochastic SIR-SI model which involve the Bayesian description. This stochastic model then is used in the relative risk formulation in order to obtain the posterior relative risk estimation. Then, this relative estimation model is demonstrated using Dengue and Chikungunya data of Malaysia. The viruses of these diseases are transmitted by the same type of female vector mosquito named Aedes Aegypti and Aedes Albopictus. Finally, the findings of the analysis of relative risk estimation for both Dengue and Chikungunya diseases are presented, compared and displayed in graphs and maps. The distribution from risk maps show the high and low risk area of Dengue and Chikungunya diseases occurrence. This map can be used as a tool for the prevention and control strategies for both diseases.

1998-01-01

Objective. Radiologists are often challenged to review CT examinations of the skull without pertinent clinical information or plain radiographs. Skull lesions of fibrous dysplasia (FD) may often be confused with Paget disease (PD). The purpose of this article is to evaluate radiographic similarities and to find the signs that can differentiate PD from FD of the skull on head CT and to describe the CT imaging features of PD and FD. Design and patients. CT scans of the skull in eight cases of PD, 18 cases of FD (13 cases of skull and facial bones, five cases of only facial bones) and 10 normals were studied retrospectively. Results. Ten features were found to be similar in PD and FD and 10 other features were found to be dissimilar. The frequency of the 10 differentiating features was evaluated to determine their reliability in distinguishing one disorder from the other. The differentiating features in order of significance include: (1) ''groundglass'' appearance, (2) symmetry, (3) involvement of the paranasal sinuses, (4) thickness of the cranial cortices, (5) involvement of the sphenoid bone, (6) orbital involvement, (7) nasal cavity involvement, (8) presence of a soft tissue mass, (9) maxillary involvement, and (10) the presence of cyst-like changes. Conclusion. These 10 signs improve the radiologist's skill in differentiating FD and PD. (orig.)

Sir Peter Medawar: science, creativity and the popularization of Karl Popper

Science.gov (United States)

Calver, Neil

2013-01-01

Sir Peter Medawar was respected by scientists and literati alike. It was perhaps not surprising, then, that he would choose to involve himself in the ‘two cultures’ debate of 1959 and beyond. The focus of his intervention was the philosophy of Sir Karl Popper. However, Medawar's Popper was not the guru of falsification familiar from philosophy textbooks. Medawar's distinctive interpretation of Popper treated him instead as the source of insights into the role of creativity and imagination in scientific inquiry. This paper traces the context for Medawar's adoption of Popperian philosophy, together with its application before the debate. It then examines, within the context of the debate itself, the way in which Medawar attempted to reconcile scientific inquiry with literary practice. Medawar became increasingly convinced that not only was induction epistemologically unsound, but it was also damaging to the public role of the scientist. His construction of Popperianism would, he envisaged, provide a worthy alternative for scientists’ self-image.

James Bay Mercury Committee report of activities. Rapport d'activites du Comite de la Baie James sur le mercure

The James Bay Mercury Committee has the mandate to oversee the implementation of the research, monitoring, and remediation programs related to the mercury pollution problem associated with hydroelectric developments in the James Bay region of Quebec. A summary of activities for 1990-91 is presented. Monitoring programs conducted during the year included studies of fish in the western part of the LaGrande complex, in which a decrease in Hg levels first noted in 1990 persisted; and a hair sampling and analysis program conducted on high-risk groups in the James Bay Cree population, which noted a continuing downward trend in Hg levels although this trend was not statistically significant. Research programs included a study of the influence of environmental factors on the release of Hg from vegetation and soil flooded by hydroelectric reservoirs. Mercury research in 1990 allowed confirmation of the fact that a higher Hg uptake in certain fish downstream from the LaGrande 2 station was related to a change in their feeding habits. Other studies were conducted on the effects of methylmercury exposure on health, sociocultural and economic aspects, and mitigative measures. Total expenditures for the year were just over $2 million. 8 refs., 3 figs., 2 tabs.

Sir Victor Horsley (1857-1916): pioneer of neurological surgery.

Science.gov (United States)

Tan, Tze-Ching; Black, Peter McL

2002-03-01

Immortalized in surgical history for the introduction of "antiseptic wax," Sir Victor Horsley played a pivotal role in shaping the face of standard neurosurgical practice. His contributions include the first laminectomy for spinal neoplasm, the first carotid ligation for cerebral aneurysm, the curved skin flap, the transcranial approach to the pituitary gland, intradural division of the trigeminal nerve root for trigeminal neuralgia, and surface marking of the cerebral cortex. A tireless scientist, he was a significant player in discovering the cure for myxedema, the eradication of rabies from England, and the invention of the Horsley-Clarke stereotactic frame. As a pathologist, Horsley performed research on bacteria and edema and founded the Journal of Pathology. Horsley's kindness, humility, and generous spirit endeared him to patients, colleagues, and students. Born to privilege, he was nonetheless dedicated to improving the lot of the common man and directed his efforts toward the suffrage of women, medical reform, and free health care for the working class. Knighted in 1902 for his many contributions to medicine, Sir Victor met an untimely death during World War I from heat stroke at the age of 59. An iconoclast of keen intellect, unlimited energy, and consummate skill, his life and work justify his epitaph as a "pioneer of neurological surgery."

Sir William Osler's speech at Troy: a Trojan horse?

Science.gov (United States)

Moran, Michael E

2012-01-01

Troy, New York, is a city of 55,000 people in upstate New York located along the Hudson River. A city of surprisingly rich cultural heritage, it was the home of New York state's first hospital outside New York City. The 50th anniversary celebration of Troy's hospital brought William Osler to the city as the keynote speaker. This speech, delivered on November 28, 1900, is one of Sir William's less well known addresses. Osler began his comments with Sir Thomas More's Utopia and talked at length about the hospital, its obligations, the influences it has upon the community, and the role of physicians and surgeons. He broached one of his old saws, the salary of attending physicians and their needed role in hospital management. His words were published in the diamond jubilee's records, but the hospital did not outlive its prominent guest professor, and it closed its doors in 1914. Just like the great historical city of Troy, New York's own Troy was on the brink of decline, and its hospital would be the first fatality. Therefore, it is almost prescient that the words of Osler, taken into historical context juxtaposed against the socioeconomic forces at work, are akin to the Greek's offering of a wooden edifice to end the Trojan War.

Extramammary Paget's disease is a rare cutaneous malignant neoplasm. Previous studies indicated the efficacy of docetaxel in advanced cases. The common side effects of docetaxel are usually tolerable and seldom life-threatening. We experienced a case of severe pseudomembranous colitis and neutropenic fever that developed just after the first cycle of docetaxel chemotherapy. To the best of our knowledge, there are few reports of pseudomembranous colitis associated with docetaxel administration for skin cancers. The patient showed complete resolution of her symptoms within 2 weeks with an oral metronidazole therapy. During the second and third cycles, the patient received docetaxel safely with lower doses. The present case indicated that pseudomembranous colitis should be included in the differential diagnosis when assessing patients who develop severe diarrhea during systemic chemotherapy with docetaxel.

In this paper, a time-delayed SIR model with a nonlinear incidence rate is considered. The existence of Hopf bifurcations at the endemic equilibrium is established by analyzing the distribution of the characteristic values. A explicit algorithm for determining the direction of the Hopf bifurcation and the stability of the bifurcating periodic solutions are derived by using the normal form and the center manifold theory. Numerical simulations to support the analytical conclusions are carried out

The use of multifrequency and polarimetric SIR-C/X-SAR data in geologic studies of Bir Safsaf, Egypt

Schaber, G.G.; McCauley, J.F.; Breed, C.S.

1997-01-01

Bir Safsaf, within the hyperarid 'core' of the Sahara in the Western Desert of Egypt, was recognized following the SIR-A and SIR-B missions in the 1980s as one of the key localities in northeast Africa, where penetration of dry sand by radar signals delineates previously unknown, sand-buried paleodrainage valleys ('radar-rivers') of middle Tertiary to Quaternary age. The Bir Safsaf area was targeted as a focal point for further research in sand penetration and geologic mapping using the multifrequency and polarimetric SIR-C/X-SAR sensors. Analysis of the SIR-C/X-SAR data from Bir Safsaf provides important new information on the roles of multiple SAR frequency and polarimetry in portraying specific types of geologic units, materials, and structures mostly hidden from view on the ground and on Landsat TM images by a relatively thin, but extensive blanket of blow sand. Basement rock units (granitoids and gneisses) and the fractures associated with them at Bir Safsaf are shown here for the first time to be clearly delineated using C- and L-band SAR images. The detectability of most geologic features is dependent primarily on radar frequency, as shown for wind erosion patterns in bedrock at X-band (3 cm wavelength), and for geologic units and sand and clay-filled fractures in weathered crystal-line basement rocks at C-band (6 cm) and L-band (24 cm). By contrast, Quaternary paleodrainage channels are detectable at all three radar frequencies owing, among other things, to an usually thin cover of blow sand. The SIR-C/X-SAR data investigated to date enable us to make specific recommendations about the utility of certain radar sensor configurations for geologic and paleoenvironmental reconnaissance in desert regions.Analysis of the shuttle imaging radar-C/X-synthetic aperture radar (SIR-C/X-SAR) data from Bir Safsaf provides important new information on the roles of multiple SAR frequency and polarimetry in portraying specific types of geologic units, materials, and

An eighteen-year meteorological diary and tree ring data from James Madison's Montpelier plantation provide a consistent reconstruction of early summer and prior fall rainfall for the 18th Century Virginia piedmont. The Madison meteorological diary suggests a seasonal shift in monthly rainfall towards an earlier wet season relative to 20th Century norms. Furthermore, dendroclimatic reconstructions of early summer and prior fall rainfall reflect this shift in the seasonality of summer rainfall. The most pronounced early summer drought during the Madison diary period is presented as a case study. This 1792 drought occurs during one of the strongest El Niño events on record and is highlighted in the correspondence of James Madison.

The delusion of the Master: the last days of Henry James.

Science.gov (United States)

Bartolomeo, Paolo

2013-11-01

The novelist Henry James shared with his brother William, the author of the Principles of Psychology, a deep interest in the ways in which personal identity is built through one's history and experiences. At the end of his life, Henry James suffered a vascular stroke in the right hemisphere and developed a striking identity delusion. He dictated in a perfectly clear and coherent manner two letters as if they were written by Napoleon Bonaparte. He also showed signs of reduplicative paramnesia. Negative symptoms resulting from right hemisphere damage may disrupt the feelings of "warmth and intimacy and immediacy" and the "resemblance among the parts of a continuum of feelings (especially bodily feelings)", which are the foundation of personal identity according to William James. On the other hand, a left hemisphere receiving inadequate input from the damaged right hemisphere may produce positive symptoms such as delusional, confabulatory narratives. Other fragments dictated during Henry James's final disease reveal some form of insight, if partial and disintegrated, into his condition. Thus, even when consciousness is impaired by brain damage, something of its deep nature may persist, as attested by the literary characteristics of the last fragments of the Master.

Paget-Schroetter syndrome (PSS) is a rare presentation of primary axillary subclavian vein thrombosis that classically occurs in young men with a degree of underlying thoracic outlet syndrome after a period of upper extremity exertion. The primary complication of PSS is post-thrombotic syndrome, a result of chronic venous hypertension. To educate Emergency Physicians on this condition to potentiate timely diagnosis and appropriate disposition. A 29-year-old right-handed restaurant waiter presented with 3 days of non-painful, gradual-onset right upper extremity swelling with normal vital signs. The patient's history was otherwise notable for subjective fevers and a right forearm abrasion. Upon examination, the right upper extremity was neurovascularly intact and remarkable for uniform edema and erythema extending distally from the level of the mid-humerus. The primary differential diagnoses were deep venous thrombosis (DVT) vs. soft tissue infection. Venous phase contrast computed tomography did not reveal evidence of underlying soft tissue infection and was inconclusive regarding a DVT. Ultrasound demonstrated a right subclavian vein DVT. The patient was admitted and underwent thrombolysis, venolysis, and first rib resection and initiation of warfarin. PSS is a rare presentation of upper-extremity DVT occurring classically in patients without commonly recognized pro-thrombotic risk factors. PSS carries the potential of significant morbidity in the form of post-thrombotic syndrome and pulmonary embolism. Current literature suggests that optimal outcomes are achieved when treatment is initiated within 6 weeks of onset. The treatment paradigm calls for thrombolysis and, frequently, a first rib resection. Copyright © 2013 Elsevier Inc. All rights reserved.

Sir Victor Horsley: pioneer craniopharyngioma surgeon.

Science.gov (United States)

Pascual, José M; Prieto, Ruth; Mazzarello, Paolo

2015-07-01

Sir Victor Horsley (1857-1916) is considered to be the pioneer of pituitary surgery. He is known to have performed the first surgical operation on the pituitary gland in 1889, and in 1906 he stated that he had operated on 10 patients with pituitary tumors. He did not publish the details of these procedures nor did he provide evidence of the pathology of the pituitary lesions operated on. Four of the patients underwent surgery at the National Hospital for Neurology and Neurosurgery (Queen Square, London), and the records of those cases were recently retrieved and analyzed by members of the hospital staff. The remaining cases corresponded to private operations whose records were presumably kept in Horsley's personal notebooks, most of which have been lost. In this paper, the authors have investigated the only scientific monograph providing a complete account of the pituitary surgeries that Horsley performed in his private practice, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), written in 1911 by Giovanni Verga, Italian assistant professor of anatomy at the University of Pavia. They have traced the life and work of this little-known physician who contributed to the preservation of Horsley's legacy in pituitary surgery. Within Verga's pituitary treatise, a full transcription of Horsley's notes is provided for 10 pituitary cases, including the patients' clinical symptoms, surgical techniques employed, intraoperative findings, and the outcome of surgery. The descriptions of the topographical and macroscopic features of two of the lesions correspond unmistakably to the features of craniopharyngiomas, one of the squamous-papillary type and one of the adamantinomatous type. The former lesion was found on necropsy after the patient's sudden death following a temporal osteoplastic craniectomy. Surgical removal of the lesion in the latter case, with the assumed nature of an adamantinomatous craniopharyngioma, was successful. According to the

Numerous cases of young children who report memories of previous lives have been studied over the last 50 years. Though such cases are more easily found in cultures that have a general belief in reincarnation, they occur in the West as well. This article describes the case of James Leininger, an American child who at age two began having intense nightmares of a plane crash. He then described being an American pilot who was killed when his plane was shot down by the Japanese. He gave details that included the name of an American aircraft carrier, the first and last name of a friend who was on the ship with him, and a location and other specifics about the fatal crash. His parents eventually discovered a close correspondence between James׳s statements and the death of a World War II pilot named James Huston. Documentation of James׳s statements that was made before Huston was identified includes a television interview with his parents that never aired but which the author has been able to review.

Physiology as the antechamber to metaphysics: the young William James's hope for a philosophical psychology.

Science.gov (United States)

Croce, P J

1999-11-01

In the 5 years before 1878, when his career in psychology was becoming established, William James wrote a series of notes and reviews assessing the work of many of the pioneers in the new field. Adopting a public and confident voice, even while he was privately still uncertain and searching, James criticized the dogmatism of positivist and idealist claims to the study of the human brain and mind. In his short writings of 1873-1877, James started to formulate his own middle path. His first steps on that path show that he did not reject either scientific or philosophic inquiry; instead, he viewed scientific knowledge as a way to understand philosophical questions more deeply. Saving his sharpest critiques for positivism, James endorsed scientific investigation without materialist assmptions. While his career in psychology was still only a hope, James treated science as a means toward humanist insight.

King James II in Foreign Historiography: the Main Scientifi c Trends and Approaches .

Full Text Available The fate of the tragic figure of the British king James II Stuart is considered in the article. In this paper the author pays speсial attention to the history of investigation of the character and politics of this person by the British historians, as well as by the leading European and American specialists on the Early Modern Time. The estimates of James II are of vast variety in the British historiography but at the same time diff erent authors have some similar features in their attitude. Except the apologists the British historians on the whole criticized this king and explain that the majority of the problems connected with him are based on the religious factor that is not really right. On the other hand there are some differences in this negative approaches among various scientifi c schools of British historiography. The Whigs stated that James II tried to limit the personal rights of the Englishmen which was the main result of the English revolution of the middle of the 17th century. The Tories proved that the king neglected the gentry’s property rights and tried to transform the dualistic monarchy into absolutism. The Positivists thought that James II supported the Catholic Counterreformation and fought against the Enlightenment. The revisionists and postrevisionists tried to revalue the person of James II based on the true scientific foundations. A special view on James II’ policy is produced by Non-British authors: German, French and American historians.

Bases do pensamento fenomenológico e existencial em William James

Directory of Open Access Journals (Sweden)

Ana Maria Lopez Calvo de Feijoo

Full Text Available Neste artigo, temos por objetivo investigar os fundamentos e as bases do pensamento fenomenológico e existencial advindos da Psicologia de William James no que diz respeito à noção de consciência, método e prática clínica. Para tanto, analisamos algumas obras de James e dividimos as suas propostas em três momentos distintos: pragmatismo, funcionalismo e empirismo. Por meio das elaborações em cada um desses momentos, tentamos esclarecer os pontos de encontro e os pontos de desencontro com os pensamentos fenomenológico e existencial. Concluímos que o ponto de encontro diz respeito à tentativa de não objetivação da consciência. Quanto ao desencontro, consideramos que James ainda toma a consciência como objeto da Psicologia e que a fenomenologia e as perspectivas existenciais se afastam da ideia de objeto, uma vez que não consideram a consciência contraposta ao mundo. Outro desencontro apresenta-se na acentuada divergência entre James e o pensamento fenomenológico e existencial no que se refere ao método e à prática bem como aos objetivos da clínica.

James Brown, Sample Culture and the Permanent Distance of Glory

Steve Jones

Full Text Available The James Brown song ‘I’m Real’ (1988 features lyrics regaled from James Brown’s back catalogue, alongside vocal samples extracted from his earlier hits. As one of the most sampled artists of the hip-hop era, James employed sampling in order to reclaim his position as the “Godfather of Soul” and express his disatisfaction at having his work overtly plundered. The central questions I pose here focus on what the choice to sample himself reveals about Brown’s status as a Soul legend, and whether the contemporaneous James could sincerely live up to the mythic status inherent to the message of ‘I’m Real’ given its self-conscious form. This confusion appears to be an extension of Walter Benjamin’s conception of déjà vu as an acoustic effect - ‘the cool tomb of long ago, from the vault of which the present seems to return only as an echo’ (Benjamin cited in Breyley, 2009: 145 - only here the slippage between past and present is quite literal, involving the discordant imbrication of two divergent temporal states. Via a detailed investigation of the song ‘I’m Real‘, I will probe Brown’s playful employment of his own past. His gambit, I will argue, may be read simultaneously as testament to his own glory, and as a signifier that the excesses of egotistic auto-projection were always more distant than they first appeared to be.

A buoyancy-based screen of Drosophila larvae for fat-storage mutants reveals a role for Sir2 in coupling fat storage to nutrient availability.

Directory of Open Access Journals (Sweden)

Tânia Reis

Full Text Available Obesity has a strong genetic component, but few of the genes that predispose to obesity are known. Genetic screens in invertebrates have the potential to identify genes and pathways that regulate the levels of stored fat, many of which are likely to be conserved in humans. To facilitate such screens, we have developed a simple buoyancy-based screening method for identifying mutant Drosophila larvae with increased levels of stored fat. Using this approach, we have identified 66 genes that when mutated increase organismal fat levels. Among these was a sirtuin family member, Sir2. Sirtuins regulate the storage and metabolism of carbohydrates and lipids by deacetylating key regulatory proteins. However, since mammalian sirtuins function in many tissues in different ways, it has been difficult to define their role in energy homeostasis accurately under normal feeding conditions. We show that knockdown of Sir2 in the larval fat body results in increased fat levels. Moreover, using genetic mosaics, we demonstrate that Sir2 restricts fat accumulation in individual cells of the fat body in a cell-autonomous manner. Consistent with this function, changes in the expression of metabolic enzymes in Sir2 mutants point to a shift away from catabolism. Surprisingly, although Sir2 is typically upregulated under conditions of starvation, Sir2 mutant larvae survive better than wild type under conditions of amino-acid starvation as long as sugars are provided. Our findings point to a Sir2-mediated pathway that activates a catabolic response to amino-acid starvation irrespective of the sugar content of the diet.

Thrombopoietin (TPO), a growth factor primarily involved in regulating thrombopoiesis, has been recently implicated in the pathogenesis of sepsis. TPO levels are, indeed, greatly increased in patients with sepsis compared to control subjects, and correlate with sepsis severity. The aim of this study was to evaluate TPO as predictive biomarker of sepsis and of sepsis severity in patients entering the emergency department (ED) with systemic inflammatory response syndrome (SIRS). This was a prospective observational study. Ours is a sub-study of the 'Need-speed trial', a multi-center observational study involving six Italian centers affiliated to the GREAT Italian Network. TPO was measured by ELISA. We enrolled 13 patients with SIRS (6 with acute pancreatitis, 3 with acute heart failure, 1 with pulmonary embolism, and 3 with allergic reactions), and 40 patients with sepsis, eight of whom had severe sepsis and three septic shock. TPO was significantly higher in patients with sepsis than with SIRS. In addition, TPO was higher in patients with severe sepsis than with sepsis, and in patients with septic shock than with severe sepsis, although these differences did not reach the statistical significance. Our preliminary results suggest that TPO may have the potential to be considered a promising early biomarker for both the diagnosis of sepsis and the assessment of sepsis severity in patients with SIRS entering the ED.

Little Book, Big Waves: The Epistle of James and Global Stewardship in Bioethics

Directory of Open Access Journals (Sweden)

Lora Jean Brake

2016-03-01

Full Text Available At first glance the twenty-first century arena of biotechnology and bioethics seems worlds away from the practical concerns of the first century outlook of the New Testament book of James. A closer look, however, reveals that the issues that James addresses have applications to challenges in bioethics. This article will give an overview of James and examine James’ teaching on wealth, poverty, and generosity and its import for the issue of global stewardship in bioethics.  Stewardship concerns both a Christian’s care and management of time, talents, and treasures.  Faithful use of the resources God has given demonstrates the fruitful faith that James writes of in his epistle. The idea of global stewardship, though “stewardship” is grounded in a distinctly Christian ethic, reflects an emerging discussion in bioethics regarding the need to address the inequities present between the money and time spent on biotechnology in some of the world in proportion to the money spent on meeting the basic healthcare needs of the poor of the entire world.  This New Testament epistle gives clear indications of how the Christian is to view wealth and how the Christian is to respond to poverty.  James, though a comparatively small book, sends a crucial message across the years that should greatly impact how Christians view stewardship in terms of global healthcare needs.

Byung Jun Kim

2014-11-01

Full Text Available BackgroundExtramammary Paget's disease (EMPD is an intraepithelial carcinoma usually occurring on the skin or mucosa of the perineum. Clinically, it resembles eczema or dermatitis, and misdiagnosis and treatment delays are common. The treatment of choice for EMPD is a wide excision with adequate margins. Wide excision with intraoperative frozen biopsy and Mohs micrographic surgery are common methods; however, these are associated with a high recurrence rate and long operation time, respectively.MethodsBetween January 2010 and June 2013, 21 patients diagnosed with EMPD underwent mapping biopsy. Biopsy specimens were collected from at least 10 areas, 2 cm from the tumor margin. When the specimens were positive for malignancy, additional mapping biopsy was performed around the biopsy site of the positive result, and continued until no cancer cells were found. Based on the results, excision margins and reconstruction plans were established preoperatively.ResultsThe patients (18 male, 3 female had a mean age of 66.5 years (range, 50-82 years. Almost all cases involved in the perineal area, except one case of axillary involvement. Permanent biopsy revealed one case (4.8% of positive cancer cells on the resection margin, in which additional mapping biopsy and re-operation was performed. At the latest follow-up (mean, 27.4 months; range, 12-53 months, recurrence had not occurred.ConclusionsPreoperative mapping biopsy enables accurate resection margins and a preoperative reconstructing plan. Additionally, it reduces the operation time and risk of recurrence. Accordingly, it represents an effective alternative to Mohs micrographic surgery and wide excision with intraoperative frozen biopsy.

The optimal dynamic immunization under a controlled heterogeneous node-based SIRS model

Yang, Lu-Xing; Draief, Moez; Yang, Xiaofan

2016-05-01

Dynamic immunizations, under which the state of the propagation network of electronic viruses can be changed by adjusting the control measures, are regarded as an alternative to static immunizations. This paper addresses the optimal dynamical immunization under the widely accepted SIRS assumption. First, based on a controlled heterogeneous node-based SIRS model, an optimal control problem capturing the optimal dynamical immunization is formulated. Second, the existence of an optimal dynamical immunization scheme is shown, and the corresponding optimality system is derived. Next, some numerical examples are given to show that an optimal immunization strategy can be worked out by numerically solving the optimality system, from which it is found that the network topology has a complex impact on the optimal immunization strategy. Finally, the difference between a payoff and the minimum payoff is estimated in terms of the deviation of the corresponding immunization strategy from the optimal immunization strategy. The proposed optimal immunization scheme is justified, because it can achieve a low level of infections at a low cost.

The global dynamics of an SIRS model with a nonlinear incidence rate is investigated. We establish a threshold for a disease to be extinct or endemic, analyze the existence and asymptotic stability of equilibria, and verify the existence of bistable states, i.e., a stable disease free equilibrium and a stable endemic equilibrium or a stable limit cycle. In particular, we find that the model admits stability switches as a parameter changes. We also investigate the backward bifurcation, the Hopf bifurcation and Bogdanov-Takens bifurcation and obtain the Hopf bifurcation criteria and Bogdanov-Takens bifurcation curves, which are important for making strategies for controlling a disease

The poor in the Epistle of James and the Gospel of Thomas

Directory of Open Access Journals (Sweden)

Patrick J. Hartin

1997-12-01

Full Text Available This study explores similarities in the thought world of the Epistle of James and the Gospel of Thomas. Particular attention is devoted to the role that the 'poor' and 'poverty' play in both documents. For the Epistle of James it is 'the poor in the world that God has chosen to be rich in faith and heirs of the kingdom' (Ja 2:5.  In a similar vein, in the Gospel of Thomas the kingdom is promised to those who have embraced the poverty of a radical life-style: 'Blessed are the poor, for yours is the kingdom of heaven' (GTh 54. This outlook betrays a basic ethos adopted toward the world. In both the Epistle of James and the Gospel of Thomas the relationship to the world ultimately determines one's relationship to the kingdom or to God. For the Epistle of James the very definition of religion demands that one keep 'oneself unstained from  the world' (Ja 1 :27 and that 'friendship with the world' is enmity with God (Ja 4:4. For the Gospel of Thomas the rejection of the world involves a radical ethos that embraces an intinerant life ('Be passersby' [GTh 42J, which includes a rejection of wealth (GTh 63.'If you do not abstain from the world, you will not find the kingdom' (GTh 27. It is argued that the Gospel of Thomas and the Epistle of James reflect traditional sayings that endorse a similar ethos of radical discipleship.

Mutations that Allow SIR2 Orthologs to Function in a NAD+-Depleted Environment.

Sirtuin enzymes depend on NAD + to catalyze protein deacetylation. Therefore, the lowering of NAD + during aging leads to decreased sirtuin activity and may speed up aging processes in laboratory animals and humans. In this study, we used a genetic screen to identify two mutations in the catalytic domain of yeast Sir2 that allow the enzyme to function in an NAD + -depleted environment. These mutant enzymes give rise to a significant increase of yeast replicative lifespan and increase deacetylation by the Sir2 ortholog, SIRT1, in mammalian cells. Our data suggest that these mutations increase the stability of the conserved catalytic sirtuin domain, thereby increasing the catalytic efficiency of the mutant enzymes. Our approach to identifying sirtuin mutants that permit function in NAD + -limited environments may inform the design of small molecules that can maintain sirtuin activity in aging organisms.

Ecrire et souffrir : L’inspiration partagée de Constance Fenimore Woolson et de Henry James Literature and Grief: Constance Fenimore Woolson and Henry James, A Common Inspiration

Directory of Open Access Journals (Sweden)

Jeannine Hayat

2007-01-01

Full Text Available Miss Grief is a story by Constance Fenimore Woolson, an American novelist who often wrote about the difficulty a woman had in becoming an artist — a writer or a painter — in the nineteenth century. This tale is a very strange text, a kind of anticipation of a meeting to come, in Italy, in 1880, between Woolson and Henry James, and a friendship which lasted until the former’s death in 1894. For thirteen years, both writers would share a common inspiration. Death itself could not break the links between the two authors, who were connected even when settled in different European countries. William James, who was a member of the American Society for Psychical Research, probably helped his brother Henry to communicate — or so it appears — in some way with Woolson, even after her fatal accident, or possible suicide, in Venice. Henry James probably had in mind Miss Grief, a story by his dead friend, before writing some of his books. Indeed, Woolson had been the first to develop the image of “the figure in the carpet,” which was later transformed by Henry James. Woolson was also the first to devise a plot which Henry James would later use as a canvas for his novel The Wings of the Dove. What is an author and what is authorship? It seems impossible to separate what is Woolson’s and what is Henry James’s in four works of fiction that are in fact to be read together : Miss Grief, The Figure in the Carpet, The Beast in the Jungle, The Wings of the Dove.

Bora Bora, Tahaa, and Raiatea, French Polynesia, Landsat and SIR-C Images Compared to SRTM Shaded

Science.gov (United States)

2005-01-01

Bora Bora, Tahaa, and Raiatea (top to bottom) are Polynesian Islands about 220 kilometers (135 miles) west-northwest of Tahiti in the South Pacific. Each of the islands is surrounded by a coral reef and its associated islets ('motus') that enclose a lagoon. Actually, as seen here, Tahaa and Raiatea are close enough together to share a common lagoon and reef. These islands are volcanic in origin and were built up from the sea floor by lava extrusions millions of years ago. None is now active, and all are deeply eroded. This display compares three differing 'views from space' of these islands. On the left, an image from the Landsat 7 satellite shows the islands as they might have appeared to an astronaut in orbit in 1999 (but a little sharper and with atmospheric haze suppressed). In the middle is an image created from data gathered by the third-generation Shuttle Imaging Radar (SIR-C), flown in 1994. On the right is a graphic illustrating elevation data gathered by the Shuttle Radar Topography Mission (SRTM) in 2000. Each of these images shows very different information as compared to the other two. Landsat sees clouds, which are almost always above these islands, blocking the view of the terrain. It also readily sees through shallow water down to the reefs. SIR-C sees the waves and other effects of winds upon the ocean surface. It does not look through water to see the reefs, but it clearly separates land and water. It also provides a bolder (but distorted) view of the islands' topographic patterns. With the ability of radar to see through clouds and provision of its own illumination, the SIR-C view is not limited by clouds nor their shadows. SRTM was designed to provide new information that is missing in the Landsat and SIR-C views. Specifically, SRTM created the world's first near-global, detailed elevation model. Natural topographic shading in Landsat imagery and radar topographic shadowing of SIR-C give some evidence of the shape of the ground but do not

Henry James – Modern Theoretician of Narration

Directory of Open Access Journals (Sweden)

Alexandra - Denisa IGNA

2013-01-01

Full Text Available Henry James, properly named world writer, was one of the first modern novelists, with an exigent writing conscience. The American writer subverted the prejudgement of the omniscient author in favour of the narration which is centred on the characters’ point of view, thus modernising the novel before V. Woolf, Huxley, Thomas Mann, or in our case Camil Petrescu and G. Călinescu. Some bio-bibliographical information familiarises the reader with the life and work of this writer. The larger part of the article is dedicated to a case study of the novel with the metaphorical title: The Figure in the Carpet, where Henry James tries to illustrate in an artistic manner his conception regarding the profundity and ineffability of the literary creation. The conclusion which the author reaches, alternating the familiar plan of the relationship between a married couple with the esthetical plan, is that the relationship between writer and his work represents an act of fully intimacy, just like a ceremony that takes place in the wedding night

The gut is an important target organ of injury during critically ill conditions. Although Gram staining is a common and quick method for identifying bacteria, its clinical application has not been fully evaluated in critically ill conditions. This study's aims were to identify patterns of Gram-stained fecal flora and compare them to cultured bacterial counts and to investigate the association between the patterns and septic complications in patients with severe systemic inflammatory response syndrome (SIRS). Fifty-two patients with SIRS were included whose Gram-stained fecal flora was classified into three patterns. In a diverse pattern, large numbers of multiple kinds of bacteria completely covered the field. In a single pattern, one specific kind of bacteria or fungi predominantly covered the field. In a depleted pattern, most bacteria were diminished in the field. In the analysis of fecal flora, the numbers of total obligate anaerobes in the depleted pattern was significantly lower than those in the diverse pattern and single pattern (p Gram-stained fecal flora can be classified into three patterns and are associated with both cultured bacterial counts and clinical information. Gram-stained fecal bacteria can be used as a quick bedside diagnostic marker for severe SIRS patients.

Full Text Available La frontière entre la santé et la pathologie est un lieu fascinant et dangereux, au caractère poreux et riche de familiarités des deux côtés, inavouées et coûteuses. Le terme d’addiction semble s’installer précisément sur cette frontière, gagnant en étendue médiatique ce qu’il perd en précision nosographique ; ainsi, aujourd’hui, nous serions « tous addicts » – au sucre, au téléphone portable, au chocolat, au café, aux soldes, à la chirurgie esthétique, à Facebook, à l’amour, cette liste pouvant être continuée par chacun d’entre nous puisque nous avons tous fait, nous faisons et ferons tous, l’expérience de la force des (mauvaises habitudes, du désir, voire de la pulsion, de l’abus et de la dépendance. Notre société contemporaine semble stimuler cette expérience, en multipliant tant les objets addictogènes que les comportements addictifs : d’une part par le statut attribué aux biens sériels, d’autre part par la dimension pulsionnelle revendiquée dans les habitudes de consommation. Société du plaisir, peut-être plus hédoniste qu’épicurienne, l’époque contemporaine impose le plaisir et son désir comme nouvelle norme. Dès lors, quel est notre rapport à la pulsion, au désir compulsif, au dépassement des limites imposées aux besoins et aux envies socialement acceptables ? Comment notre société régule le désir ? Comment la politique et les médias concourent-ils à le structurer, voire à le prescrire ? Quels mécanismes à l’œuvre dans l’addiction contredisent cette prescription, et surtout : s’agit-il véritablement d’une contradiction ? Notre culture de performance et satisfaction rapides peut effectivement expliquer certaines dépendances induites par leur objet ; néanmoins, la véritable addiction mentale se nourrit d’éléments plus profondément constitutifs de l’identité de l’homme moderne et contemporain : avant tout, la fragilité des acquis, la

2014-08-01

Vector-borne diseases are one of the major public health problems in the world with the fastest spreading rate. Control measures have been focused on vector control, with poor results in most cases. Vaccines should help to reduce the diseases incidence, but vaccination strategies should also be defined. In this work, we propose a vector-transmitted SIR disease model with age-structured population subject to a vaccination program. We find an expression for the age-dependent basic reproductive number R(0), and we show that the disease-free equilibrium is locally stable for R(0) ≤ 1, and a unique endemic equilibrium exists for R(0) > 1. We apply the theoretical results to public data to evaluate vaccination strategies, immunization levels, and optimal age of vaccination for dengue disease.

Impulsive vaccination and dispersal on dynamics of an SIR epidemic model with restricting infected individuals boarding transports

Science.gov (United States)

Jiao, Jianjun; Cai, Shaohong; Li, Limei

2016-05-01

To understand the effect of impulsive vaccination and restricting infected individuals boarding transports on disease spread, we establish an SIR model with impulsive vaccination, impulsive dispersal and restricting infected individuals boarding transports. This SIR epidemic model for two regions, which are connected by transportation of non-infected individuals, portrays the evolvement of diseases. We prove that all solutions of the investigated system are uniformly ultimately bounded. We also prove that there exists globally asymptotically stable infection-free boundary periodic solution. The condition for permanence is discussed. It is concluded that the approach of impulsive vaccination and restricting infected individuals boarding transports provides reliable tactic basis for preventing disease spread.

We aimed to examine smoking-related content in all 24 James Bond movies in the Eon Productions series from 1962 to 2015. There were favourable downward trends for any smoking by James Bond (p=0.015 for trend), and for tobacco-related spy-gadgetry (p=0.009). Around 20% of Bond's 60 sexual partners smoked in each decade, and most recently in 2012. There were regular mentions of smoking risks to health (starting from 1967) and product placement of branded packs was present in two movies. Overall, the persisting smoking content remains problematic from a public health perspective, especially given the popularity of this movie series. Published by the BMJ Publishing Group Limited.

[Sir Francis Galton: the father of eugenics].

Science.gov (United States)

Aubert-Marson, Dominique

2009-01-01

Not only was Sir Francis Galton a famous geographer and statistician, he also invented "eugenics" in 1883. Eugenics, defined as the science of improving racial stock, was developed from a new heredity theory, conceived by Galton himself, and from the evolution theory of Charles Darwin, transposed to human society by Herbert Spencer. Galton's eugenics was a program to artificially produce a better human race through regulating marriage and thus procreation. Galton put particular emphasis on "positive eugenics", aimed at encouraging the physically and mentally superior members of the population to choose partners with similar traits. In 1904, he presented his ideas in front of a vast audience of physicians and scientists in London. His widely-publicized lecture served as the starting point for the development of eugenics groups in Europe and the United States during the first half of the 20th century.

Influence of heat conductivity on the performance of RTV SIR coatings with different fillers

Room temperature vulcanized silicone rubber (RTV SIR) coatings are employed in order to improve the pollution performance of high voltage ceramic insulators by imparting surface hydrophobicity. In this paper, the performance of three RTV SIR coatings containing different fillers is investigated in a salt-fog test. Alumina trihydrate (ATH) and silica are the fillers included in the formulation, aiming to increase the material endurance to the energy supplied by the surface electrical activity during periods of hydrophobicity loss. The primary action of these fillers is to increase the material heat conductivity, i.e. the amount of energy conducted to the substrate. In addition, in the case of ATH relief is also achieved due to particle decomposition. The results indicate that for the compositions commercially available, where low amounts of fillers are used, and under the conditions of the test, ATH filled coatings performed better than the silica filled ones. This is attributed to ATH decomposition which further relieves the material structure and therefore decelerates material aging.

Nicotinamide supplementation phenocopies SIR2 inactivation by modulating carbon metabolism and respiration during yeast chronological aging.

Science.gov (United States)

Orlandi, Ivan; Pellegrino Coppola, Damiano; Strippoli, Maurizio; Ronzulli, Rossella; Vai, Marina

2017-01-01

Nicotinamide (NAM), a form of vitamin B 3 , is a byproduct and noncompetitive inhibitor of the deacetylation reaction catalyzed by Sirtuins. These represent a family of evolutionarily conserved NAD + -dependent deacetylases that are well-known critical regulators of metabolism and aging and whose founding member is Sir2 of Saccharomyces cerevisiae. Here, we investigated the effects of NAM supplementation in the context of yeast chronological aging, the established model for studying aging of postmitotic quiescent mammalian cells. Our data show that NAM supplementation at the diauxic shift results in a phenocopy of chronologically aging sir2Δ cells. In fact, NAM-supplemented cells display the same chronological lifespan extension both in expired medium and extreme Calorie Restriction. Furthermore, NAM allows the cells to push their metabolism toward the same outcomes of sir2Δ cells by elevating the level of the acetylated Pck1. Both these cells have the same metabolic changes that concern not only anabolic pathways such as an increased gluconeogenesis but also respiratory activity in terms both of respiratory rate and state of respiration. In particular, they have a higher respiratory reserve capacity and a lower non-phosphorylating respiration that in concert with a low burden of superoxide anions can affect positively chronological aging.

SIR (Safe Integral Reactor) - reducing size can reduce cost

International Nuclear Information System (INIS)

Hayns, M.R.

1991-01-01

Traditional engineering economics have favoured the advantages of larger size as a means of reducing specific capital costs and hence unit generating costs. For large and small plants utilising the same concept, e.g. a small four-loop PWR vs a large four-loop PWR with the same number of components, economies of scale are well established. If, however, a smaller plant is sized to take advantage of features which are only feasible at smaller outputs, is of simpler design, with the advantage taken of the simplified design to produce the most cost-effective layout, and incorporates fewer, more easily replaceable components with minimal assembly on site, it is possible to produce a plant which is competitive with larger plant of more traditional design. When 'system' effects, such as better matching of installed capacity to the growth in demand and the fact that a smaller total capacity will be needed to meet a given demand with a specified level of confidence, are taken into account, it can be shown that a utility's overall cash-flow position can be improved with lower associated absolute financial risks. The UK/US Safe Integral Reactor (SIR) is an integral pressurized water reactor in the 300-400 MW(e) range which utilises conventional water reactor technology in a way not feasible at the very large, sizes of recent years. The SIR concept is briefly explained and its technical and economic advantages in terms of simplicity, construction, maintenance, availability, decommissioning, safety and siting described. The results of system analyses which demonstrate the overall financial advantages to a utility are presented. (author)

The aim of this study was to evaluate procalcitonin (PCT), C-reactive protein (CRP), platelet count (PLT) and serum lactate dehydrogenase (LDH) as early markers for diagnosis of SIRS, bacterial sepsis and systemic candidiasis in intensive care unit (ICU) patients. Based on blood culture results, the patients were divided into a sepsis group (70 patients), a SIRS group (42 patients) and a systemic candidiasis group (33 patients). PCT, CRP, LDH and PLT levels were measured on day 0 and on day 2 from the sepsis symptom onset. PCT levels were higher in Gram negative sepsis than those in Gram positive sepsis, although the P value between the two subgroups is not significant (P=0.095). Bacterial sepsis group had higher PCT and CRP levels compared with the systemic candidiasis group, whereas PLT and LDH levels showed similar levels in these two subgroups. The AUC for PCT (AUC: 0.892, P candidiasis groups (P=0.093 N.S.). In conclusion, PCT can be used as a preliminary marker in the event of clinical suspicion of systemic candidiasis; however, low PCT levels (candidiasis and SIRS groups.

Investigating Environmentally Sustainable Transport Based on DALY weights and SIR Method

Directory of Open Access Journals (Sweden)

Hossein Nezamianpour Jahromi

2012-09-01

Full Text Available Accessibility is one of the main causes of well-being and growth in contemporary societies. Transportation is the backbone of accessibility systems that lead to the growth of economic and social networks and spatial dispersion of activities. Unfortunately, the adverse effects of transportation have a great impact on the natural and human environment. Since transportation is associated with fossil fuel combustion, it results in emissions of pollutants that cause damage to human health. To save the global eco-system, sustainable development has become an international priority. To deal with the sustainability of transportation systems is an important issue as testified by a growing number of initiatives framed to define and measure sustainability in transportation planning and infrastructure planning as well. The capability of environmental assessment as a sustainability instrument is well known. This study proposes a new approach to rank countries based on environmental sustainability development applying disability adjusted life year (DALY weights for transportation sector emissions. DALY weights consider actual impacts of pollutants on human health. By employing SIR method, a superiority and inferiority ranking method is presented for multiple criteria decision making, the sustainability ranking of a number of European countries is presented. Three various ranking methods extracted from SIR ranking method are discussed and the results and the correlation among them are demonstrated.

Carrera, Mónica; Gallardo, José M

2017-02-08

The determination of the geographical origin of food products is relevant to comply with the legal regulations of traceability, to avoid food fraud, and to guarantee food quality and safety to the consumers. For these reasons, stable isotope ratio (SIR) analysis using an isotope ratio mass spectrometry (IRMS) instrument is one of the most useful techniques for evaluating food traceability and authenticity. The present study was aimed to determine, for the first time, the geographical origin for all commercial fish species belonging to the Merlucciidae family using SIR analysis of carbon (δ 13 C) and nitrogen (δ 15 N). The specific results enabled their clear classification according to the FAO (Food and Agriculture Organization of the United Nations) fishing areas, latitude, and geographical origin in the following six different clusters: European, North African, South African, North American, South American, and Australian hake species.

Positron-emitting resin microspheres as surrogates of 90Y SIR-Spheres: a radiolabeling and stability study

Avila-Rodriguez, Miguel A.; Selwyn, Reed G.; Hampel, Joseph A.; Thomadsen, Bruce R.; DeJesus, Onofre T.; Converse, Alexander K.; Nickles, Robert J.

2007-01-01

Commercially available resin microspheres and SIR-Spheres were labeled with metallic positron emitters and evaluated as positron emission tomography (PET) imaging surrogates of 90 Y SIR-Spheres. Radiolabeling was performed using a batch method, and in vitro stability over 24 h was evaluated in saline at physiological pH at 37 o C. The activity per microsphere distribution, as evaluated by autoradiography, showed the activity per microsphere to be proportional to the square radius of the spheres, suggesting surface binding. The in vivo stability of radiolabeling was evaluated in rats by micro-PET imaging after the intravenous injection of labeled microspheres. The different resin microspheres and radionuclides evaluated in this study all showed good radiolabeling efficiency and in vitro stability. However, only resins labeled with 86 Y and 89 Zr proved to have the in vivo stability required for clinical applications

Deteriorated stress response in stationary-phase yeast: Sir2 and Yap1 are essential for Hsf1 activation by heat shock and oxidative stress, respectively.

Directory of Open Access Journals (Sweden)

Inbal Nussbaum

Full Text Available Stationary-phase cultures have been used as an important model of aging, a complex process involving multiple pathways and signaling networks. However, the molecular processes underlying stress response of non-dividing cells are poorly understood, although deteriorated stress response is one of the hallmarks of aging. The budding yeast Saccharomyces cerevisiae is a valuable model organism to study the genetics of aging, because yeast ages within days and are amenable to genetic manipulations. As a unicellular organism, yeast has evolved robust systems to respond to environmental challenges. This response is orchestrated largely by the conserved transcription factor Hsf1, which in S. cerevisiae regulates expression of multiple genes in response to diverse stresses. Here we demonstrate that Hsf1 response to heat shock and oxidative stress deteriorates during yeast transition from exponential growth to stationary-phase, whereas Hsf1 activation by glucose starvation is maintained. Overexpressing Hsf1 does not significantly improve heat shock response, indicating that Hsf1 dwindling is not the major cause for Hsf1 attenuated response in stationary-phase yeast. Rather, factors that participate in Hsf1 activation appear to be compromised. We uncover two factors, Yap1 and Sir2, which discretely function in Hsf1 activation by oxidative stress and heat shock. In Δyap1 mutant, Hsf1 does not respond to oxidative stress, while in Δsir2 mutant, Hsf1 does not respond to heat shock. Moreover, excess Sir2 mimics the heat shock response. This role of the NAD+-dependent Sir2 is supported by our finding that supplementing NAD+ precursors improves Hsf1 heat shock response in stationary-phase yeast, especially when combined with expression of excess Sir2. Finally, the combination of excess Hsf1, excess Sir2 and NAD+ precursors rejuvenates the heat shock response.

Stationary-phase cultures have been used as an important model of aging, a complex process involving multiple pathways and signaling networks. However, the molecular processes underlying stress response of non-dividing cells are poorly understood, although deteriorated stress response is one of the hallmarks of aging. The budding yeast Saccharomyces cerevisiae is a valuable model organism to study the genetics of aging, because yeast ages within days and are amenable to genetic manipulations. As a unicellular organism, yeast has evolved robust systems to respond to environmental challenges. This response is orchestrated largely by the conserved transcription factor Hsf1, which in S. cerevisiae regulates expression of multiple genes in response to diverse stresses.

The objective of this study is to investigate the influences of percutaneous nephrolithotomy (PNL) and open surgery nephrolithotomy on the systemic stress response, SIRS and renal function. Forty patients with kidney calculi were enrolled in the study. Twenty cases were randomized to the PNL group and the other twenty cases to the open surgery group. Levels of C-reactive protein (CRP), interleukin-6(IL-6), β(2)-microglobulin (β(2)-MG), respiration rate, heart rate, body temperature and white blood cell counts were examined. CRP and IL-6 were measured in all patients pre-operatively and on post-operative days 1, 3 and 6, respectively. There was significant difference in their pre- and post-operation levels (P PNL group and 12 cases in open surgery group; there was significant difference between the two groups (P 0.05). Urine β(2)-MG levels were also measured. There was significant difference between pre- and the first day post-PNL (P PNL (P > 0.05). There was significant difference between pre- and first and third day post-open surgery (P 0.05). There was significant difference between two groups at the first, third and sixth days (P PNL group and open surgery group to some extent. The degree of stress response of PNL is lower than that of open surgery, proving the advantages of PNL with reference to serum immunology. There were cases in both the groups with SIRS, but the degree of SIRS in PNL group was lesser than the other group. Both the groups have no obvious effect on glomerular filtration function after operation and have effect on renal tubular reabsorption in the early stage after operation; but the recovery of the PNL group is faster than the open surgery group. It is thus shown that PNL is much safer and more feasible and has lesser effect on renal function.

Infantile infections are thought to constitute one of the main bases of the etiology of Swyer-James syndrome. This case seems to support the above theory allowing for the anamnesis of the pleuritis at 2 years of age, bronchographical findings - bilateral but markedly left-sided bud-like bronchiectatic changes - and left pulmonary angiographical findings - simultaneous appearance of pulmonary arteries and veins with scarce capillary image. Concerning the ventilation of this syndrome, 133 Xe inhalation test showed a ''Pendelluft'' phenomenon, shift of 133 Xe from the healthy to the affected lung on forced expiration. (author)

Medicinal use of earths and minerals from Hippocrates to Sir Hans Sloane and beyond.

In 1931 two pharmaceutical drawers containing mineral specimens, belonging to Sir Hans Sloane, the 18th century collector, Royal Physician, President of the Royal Society and of the Royal College of Physicians of London, were found in the Department of Botany of the Natural History Museum (NHM) of London. The drawers, each divided into 49 compartments, contained a total of 107 mineral pharmaceutical specimens, some labelled as mercury or white arsenic. Their registration, identification with the Sloane Manuscript Catalogues and subsequent transfer to the Mineralogy department of the NHM where one of these drawers is now on public display, had been documented by 1935. In antiquity therapeutic empiricism attributed medicinal properties to animal products, plants and minerals, including the soil of specific geographic locations. This communication traces the medicinal use of certain earths and minerals, listed in Sir Hans Sloane's manuscript catalogues, to classical antiquity with a reference to Arsenic compounds, which in our time are finding application in the treatment of acute promyelocytic leukaemia and to Terra Lemnia, a celebrated antidote of repute spanning twenty centuries, also included in the Sloane collections.

Full Text Available The threshold of a stochastic SIRS model with vertical transmission and saturated incidence is investigated. If the noise is small, it is shown that the threshold of the stochastic system determines the extinction and persistence of the epidemic. In addition, we find that if the noise is large, the epidemic still prevails. Finally, numerical simulations are given to illustrate the results.

William James on a phenomenological psychology of immediate experience: the true foundation for a science of consciousness?

Science.gov (United States)

Taylor, Eugene

2010-01-01

Throughout his career, William James defended personal consciousness. In his "Principles of Psychology" (1890), he declared that psychology is the scientific study of states of consciousness as such and that he intended to presume from the outset that the thinker was the thought. But while writing it, he had been investigating a dynamic psychology of the subconscious, which found a major place in his Gifford Lectures, published as "The Varieties of Religious Experience" in 1902. This was the clearest statement James was able to make before he died with regard to his developing tripartite metaphysics of pragmatism, pluralism and radical empiricism, which essentially asked "Is a science of consciousness actually possible?" James's lineage in this regard, was inherited from an intuitive psychology of character formation that had been cast within a context of spiritual self-realization by the Swedenborgians and Transcendentalists of New England. Chief among these was his father, Henry James, Sr., and his godfather, Ralph Waldo Emerson. However, james was forced to square these ideas with the more rigorous scientific dictates of his day, which have endured to the present. As such, his ideas remain alive and vibrant, particularly among those arguing for the fusion of phenomenology, embodiment and cognitive neuroscience in the renewed search for a science of consciousness.

Doctors, disease and James Joyce.

Kaplan, Robert M

2008-08-01

The Irish author James Joyce is regarded as the greatest modernist writer of his time. His works, notably The Dead, A Portrait of the Artist as a Young Man, Ulysses and Finnegans Wake--are intensely autobiographic including meticulous descriptions of illness and states of health--no surprise in view of Joyce's medical history and hypochondria. The Dead revolves around the tragic love of a doomed tubercular youth. Ulysses has a graphic description of Mary Joyce-s death, a funeral and a birth; Stephen Dedalus, the character based on Joyce, attends a drinking session with medical students at the lying-in hospital just as Joyce had done as a student; references to syphilis, alcoholism and other illnesses abound.

Liu, Qun; Jiang, Daqing

2016-11-01

In this paper, we study the threshold dynamics of a stochastic delayed SIR epidemic model with vaccination. We obtain sufficient conditions for extinction and persistence in the mean of the epidemic. The threshold between persistence in the mean and extinction of the stochastic system is also obtained. Compared with the corresponding deterministic model, the threshold affected by the white noise is smaller than the basic reproduction number Rbar0 of the deterministic system. Results show that time delay has important effects on the persistence and extinction of the epidemic.

James Weldon Johnson and the Speech Lab Recordings

Directory of Open Access Journals (Sweden)

Chris Mustazza

2016-03-01

Full Text Available On December 24, 1935, James Weldon Johnson read thirteen of his poems at Columbia University, in a recording session engineered by Columbia Professor of Speech George W. Hibbitt and Barnard colleague Professor W. Cabell Greet, pioneers in the field that became sociolinguistics. Interested in American dialects, Greet and Hibbitt used early sound recording technologies to preserve dialect samples. In the same lab where they recorded T.S. Eliot, Gertrude Stein, and others, James Weldon Johnson read a selection of poems that included several from his seminal collection God’s Trombones and some dialect poems. Mustazza has digitized these and made them publicly available in the PennSound archive. In this essay, Mustazza contextualizes the collection, considering the recordings as sonic inscriptions alongside their textual manifestations. He argues that the collection must be heard within the frames of its production conditions—especially its recording in a speech lab—and that the sound recordings are essential elements in an hermeneutic analysis of the poems. He reasons that the poems’ original topics are reframed and refocused when historicized and contextualized within the frame of The Speech Lab Recordings.

An individual-based approach to SIR epidemics in contact networks.

Science.gov (United States)

Youssef, Mina; Scoglio, Caterina

2011-08-21

Many approaches have recently been proposed to model the spread of epidemics on networks. For instance, the Susceptible/Infected/Recovered (SIR) compartmental model has successfully been applied to different types of diseases that spread out among humans and animals. When this model is applied on a contact network, the centrality characteristics of the network plays an important role in the spreading process. However, current approaches only consider an aggregate representation of the network structure, which can result in inaccurate analysis. In this paper, we propose a new individual-based SIR approach, which considers the whole description of the network structure. The individual-based approach is built on a continuous time Markov chain, and it is capable of evaluating the state probability for every individual in the network. Through mathematical analysis, we rigorously confirm the existence of an epidemic threshold below which an epidemic does not propagate in the network. We also show that the epidemic threshold is inversely proportional to the maximum eigenvalue of the network. Additionally, we study the role of the whole spectrum of the network, and determine the relationship between the maximum number of infected individuals and the set of eigenvalues and eigenvectors. To validate our approach, we analytically study the deviation with respect to the continuous time Markov chain model, and we show that the new approach is accurate for a large range of infection strength. Furthermore, we compare the new approach with the well-known heterogeneous mean field approach in the literature. Ultimately, we support our theoretical results through extensive numerical evaluations and Monte Carlo simulations. Published by Elsevier Ltd.

Isonicotinamide Enhances Sir2 Protein-mediated Silencing and Longevity in Yeast by Raising Intracellular NAD+ Concentration*

Sirtuins are an evolutionarily conserved family of NAD+-dependent protein deacetylases that function in the regulation of gene transcription, cellular metabolism, and aging. Their activity requires the maintenance of an adequate intracellular NAD+ concentration through the combined action of NAD+ biosynthesis and salvage pathways. Nicotinamide (NAM) is a key NAD+ precursor that is also a byproduct and feedback inhibitor of the deacetylation reaction. In Saccharomyces cerevisiae, the nicotinamidase Pnc1 converts NAM to nicotinic acid (NA), which is then used as a substrate by the NAD+ salvage pathway enzyme NA phosphoribosyltransferase (Npt1). Isonicotinamide (INAM) is an isostere of NAM that stimulates yeast Sir2 deacetylase activity in vitro by alleviating the NAM inhibition. In this study, we determined that INAM stimulates Sir2 through an additional mechanism in vivo, which involves elevation of the intracellular NAD+ concentration. INAM enhanced normal silencing at the rDNA locus but only partially suppressed the silencing defects of an npt1Δ mutant. Yeast cells grown in media lacking NA had a short replicative life span, which was extended by INAM in a SIR2-dependent manner and correlated with increased NAD+. The INAM-induced increase in NAD+ was strongly dependent on Pnc1 and Npt1, suggesting that INAM increases flux through the NAD+ salvage pathway. Part of this effect was mediated by the NR salvage pathways, which generate NAM as a product and require Pnc1 to produce NAD+. We also provide evidence suggesting that INAM influences the expression of multiple NAD+ biosynthesis and salvage pathways to promote homeostasis during stationary phase. PMID:22539348

Full Text Available A simple and compact 4.9 GHz bandpass filter for C-band applications is proposed. This paper presents a novel microstrip cross-coupled interdigital half-wavelength stepped impedance resonator (SIR based bandpass filter (BPF.The designed structure is similar to that of a combination of two parallel interdigital capacitors. The scattering parameters of the structure are measured using vector network analyzer (VNA. The self generated capacitive and inductive reactances within the interdigital resonators exhibited in a resonance frequency of 4.9 GHz. The resonant frequency and bandwidth of the capacitive cross-coupled resonator is directly optimized from the physical arrangement of the resonators. The measured insertion loss (S21 and return loss (S11 were 0.3 dB and 28 dB, respectively, at resonance frequency which were almost close to the simulation results.

Ha, Cheol Woong; Kim, Kwantae; Chang, Yeon Ji; Kim, Bongkeun; Huh, Won-Ki

2014-07-01

In Saccharomyces cerevisiae, the stability of highly repetitive rDNA array is maintained through transcriptional silencing. Recently, a β-1,3-glucanosyltransferase Gas1 has been shown to play a significant role in the regulation of transcriptional silencing in S. cerevisiae. Here, we show that the gas1Δ mutation increases rDNA silencing in a Sir2-dependent manner. Remarkably, the gas1Δ mutation induces nuclear localization of Msn2/4 and stimulates the expression of PNC1, a gene encoding a nicotinamidase that functions as a Sir2 activator. The lack of enzymatic activity of Gas1 or treatment with a cell wall-damaging agent, Congo red, exhibits effects similar to those of the gas1Δ mutation. Furthermore, the loss of Gas1 or Congo red treatment lowers the cAMP-dependent protein kinase (PKA) activity in a cell wall integrity MAP kinase Slt2-dependent manner. Collectively, our results suggest that the dysfunction of Gas1 plays a positive role in the maintenance of rDNA integrity by decreasing PKA activity and inducing the accumulation of Msn2/4 in the nucleus. It seems that nuclear-localized Msn2/4 stimulate the expression of Pnc1, thereby enhancing the association of Sir2 with rDNA and promoting rDNA stability. © The Author(s) 2014.

Between 1875 and 1910 Sir Robert Stawell Ball gave an estimated 2,500 lectures in towns and cities all over the British Isles and abroad. This paper traces his lecturing career from its beginnings in Ireland to the triumphs of the Royal Institution, and on lecture tours in the United States of America. After a period in mathematics and mechanics, he became a populariser of science, especially astronomy, and found fame and fortune among the working classes and the aristocracy. What motivated him to tireless travels is uncertain, but it might have been that it was rewarding, financially and to his reputation. Whatever his motives, contemporary accounts are clear that BallÕs lectures were extremely popular and well-received.

Conventionally, an adaptive SIR estimator employs a moving average (MA filter (Yoon et al., 2002 to encounter fading channel distortion. However, the resulting estimate seems to have high estimation error due to fluctuation in the channel variation. In this paper, an additional post-processing stage is proposed to improve the estimation accuracy by reducing the variation of the estimate. Four variations of post-processing stages, namely 1 a moving average (MA postfilter,2 an exponential moving average (EMA post-filter, 3 an IIR post-filter and 4 least-mean-squared (LMS adaptive post-filter, are proposed and their optimal performance in terms of root-mean-square error (RMSE are then compared by simulation. The results show the best comparable performance when the MA and LMS post-filter are used. However, the MA post-filter requires a lookup table of filter order for optimal performance at different channel conditions, while the LMS post-filter can be used conveniently without a lookup table.

In this paper, an uplink power control problem is considered for code division multiple access (CDMA) systems. A distributed algorithm is proposed based on linear quadratic optimal control theory. The proposed scheme minimizes the sum of the power and the error of signal-to-interference ratio (SIR). A power controller is designed by constructing an optimization problem of a stochastic linear quadratic type in Krein space and solving a Kalman filter problem.

Soil and sediment samples from James Ross Island were analyzed for their PCB, OCP and PAH contents. Soil concentrations ranged between 0.51 and 1.82 ng g -1 for seven indicator PCB congeners, between 0.49 and 1.34 ng g -1 for HCH congeners, between 0.51 and 3.68 ng g -1 for the sum of p,p'-DDT, DDE, and DDD, and between 34.9 and 171 ng g -1 for the sum of 16 EPA PAHs. Sediment levels from 0.32 to 0.83 ng g -1 were found for PCBs, from 0.14 to 0.76 ng g -1 for HCHs, from 0.19 to 1.15 ng g -1 for DDTs, and from 1.4 to 205 ng g -1 for PAHs. A prevalence of low-mass PAHs, less chlorinated PCBs, and more volatile chemicals indicates that the long-range atmospheric transport from populated areas of Africa, South America, and Australia is the most probable contamination source for the solid matrices in James Ross Island. - A survey of soil, sediment and air contamination in James Ross Island, Antarctica serves as a baseline study for evaluation of an anthropogenic impact of the new research facility

2012-01-01

Full Text Available This article analyses the tourism websites of Spanish autonomous communities crossed by the Way of Saint James. Considering that the Way of Saint James and the Xacobeo 2010 are important touristic opportunities for these autonomous regions, the main objective of this investigation is to evaluate the information about these touristic places in their tourism websites. The analysis focused on two aspects: firstly, establishing whether the autonomous communities have used the Way of Saint James and the Xacobeo 2010 to promote themselves, and secondly, evaluating the quality of the websites. The study included a literature review, definition of concepts and criteria to measure the quality of websites, and the analysis of the content and design of the selected tourism websites. The results show that the Galician website is the most complete in terms of information about the Way of Saint James and the Xacobeo 2010. The information about the Way of Saint James and the Xacobeo 2010 in the websites of the other communities is vague and differs from one website to another. Due to the touristic significance of the Xacobeo 2010 and the importance of Internet as a medium of communication, the research group plans to conduct a new analysis of the communities’ institutional websites in 2011.

The crystallization and preliminary X-ray diffraction studies of DppA from P. pacifica SIR-I are reported. DppA from Plesiocystis pacifica SIR-I is a putative haloalkane dehalogenase (EC 3.8.1.5) and probably catalyzes the conversion of halogenated alkanes to the corresponding alcohols. The enzyme was expressed in Escherichia coli BL21 and purified to homogeneity by ammonium sulfate precipitation and reversed-phase and ion-exchange chromatography. The DppA protein was crystallized by the vapour-diffusion method and protein crystals suitable for data collection were obtained in the orthorhombic space group P2 1 2 1 2. The DppA crystal diffracted X-rays to 1.9 Å resolution using an in-house X-ray generator

“One day, Sir, you may tax it”… Those are the words I used to get the audience's attention during my talk at the World Economic Forum’s annual meeting in Davos, where I was invited to speak about the science agenda in 2011. For those of you who don’t know the quote, it was Michael Faraday’s response to William Gladstone when asked to comment on the utility of his blue-sky research into the newfangled phenomenon of electricity.   So what does a 19th century English scientist have to do with the science agenda today? A great deal, I would contend. Faraday was doing basic science, but he had the foresight to realise that through applied research his findings could one day be developed into something taxable – as it turned out, electric light. Faraday had a sense of the potential of his blue-sky research, but he also appreciated that basic science alone is not enough. This was my key message in Davos. Governments often speak of ...

Depending on populations, 15 to 40% of patients have a familial form of Paget's disease of bone (PDB), which is transmitted in an autosomal-dominant mode of inheritance with incomplete penetrance. To date, only SQSTM1 gene mutations have been linked to the disease. Several single nucleotide polymorphisms (SNPs) have been associated with PDB in patient non-carriers of SQSTM1 mutations, but they have minor size effects. The current clinical practice guidelines still recommend to measure total serum alkaline phosphatase (sALP) for PDB screening. However, genetic or bone biomarkers alone may lack sensitivity to detect PDB. Thus, the objective of this study was to develop a molecular test of PDB, combining genetic and bone biomarkers, in order to detect PDB, which is frequently asymptomatic. We genotyped 35 SNPs previously associated with PDB in 305 patients, and 292 healthy controls. In addition, serum levels of 14 bone biomarkers were assayed in 51 patients and 151 healthy controls. Bivariate and multivariate logistic regression models with adjustment for age and sex were fitted to search for a combination of SNPs and/or bone biomarkers that could best detect PDB in patient non-carriers of SQSTM1 mutations. First, a combination of five genetic markers gave rise to the highest area under the ROC curve (AUC) with 95% confidence interval [95% CI] of 0.731 [0.688; 0.773], which allowed us to detect 81.5% of patients with PDB. Second, a combination of two bone biomarkers had an AUC of 0.822 [0.726; 0.918], and was present in 81.5% of patients with PDB. Then, the combination of the five genetic markers and the two bone biomarkers increased the AUC up to 0.892 [0.833; 0.951], and detected 88.5% of patients with PDB. These results suggested that an algorithm integrating first a screen for SQSTM1 gene mutations, followed by either a genetic markers combination or a combined genetic and biochemical markers test in patients non-carrier of any SQSTM1 mutation, may detect the PDB

Power and dignity: the social consequences of hydro-electric development for the James Bay Cree

The social impact that large-scale hydro-electric development has on the Cree of James Bay following the construction of the La Grande Complex was discussed. Many environmental changes were brought about by dam construction. The project, which also involved the first settlement (the James Bay and Northern Quebec Agreement) directed at extinguishing aboriginal title to land and natural resources in Canada, resulted in several relocations of Cree communities. In addition to compensation, the Agreement included a formal procedure for environmental and social impact assessment for development projects. However, there was little commitment, as a matter of corporate or government policy, to monitoring any of the social impacts. This paper is a preliminary response to an appeal for attention to be focused on the social consequences of hydro-electric development for the Cree in James Bay. Data from social service files indicate that the rapid centralization of the James Bay Cree into structured communities led to social instability in the villages, reflected by high frequencies in suicide, neglect of children, vandalism and drug and alcohol abuse. The material presented here is expected to serve as a warning that in further developing the far North of Quebec the pace of social change in Cree society will have to be slowed down to avoid social destruction of the native communities. 15 refs., 2 tabs

Interpreting "Mind-Cure": William James and the "chief task…of the science of human nature".

Science.gov (United States)

Sutton, Emma Kate

2012-01-01

The private papers of the philosopher-psychologist, William James, indicate that he frequented several mental healers during his life, undertaking 100-200 therapeutic sessions concerning a range of symptoms from angina to insomnia. The success of the mind-cure movement constituted for James both a corroboration, and an extension, of the new research into the subconscious self and the psychogenesis of disease. Epistemologically, the experiences of those converts to the "mind-cure religion" exemplified his conviction that positivistic scientific enquiry can only reveal only one part of a wider reality. Metaphysically their reports comprised a powerful body of support for the existence of a "higher consciousness," a supernatural world of some description. The positing of such a source of "supernormal" healing power was, for James, the best way to reconcile the accounts of those who had been regenerated, via their faith, despite having exhausted all natural reserves of energy and will. © 2012 Wiley Periodicals, Inc.

'Report of the Committee on Mediumistic Phenomena', by William James (1886): With an introduction by.

Alvarado, Carlos S

2016-03-01

Mediumship was a topic of great interest to some nineteenth-century students of mental phenomena. Together with the phenomena of hypnosis and other manifestations, mediumship was seen by many as a dissociative phenomenon. The purpose of this Classic Text is to present an excerpt of an article about the topic that William James (1842-1910) published in 1886 in the Proceedings of the American Society for Psychical Research about American medium Leonora E. Piper (1857-1950). The article, an indication of late nineteenth-century interactions between dissociation studies and psychical research, was the first report of research with Mrs Piper, a widely investigated medium of great importance for the development of mediumship studies. In addition to studying the case as a dissociative experience, James explored the possibility that Piper's mentation contained verifiable information suggestive of 'supernormal' knowledge. Consequently, James provides an example of a topic neglected in historical studies, the ideas of those who combined conventional dissociation studies with psychical research. © The Author(s) 2016.

Bone Paget's disease is heterogeneously distributed and several foci of high prevalence have been reported in Spain. The aim of the present work was to determine the prevalence of the disease in a zone situated in the northwestern sector of the Province of Salamanca (Spain) using a cross sectional epidemiological study. Sample choice was based on a stratified sampling according to the residence, age and sex of the inhabitants of the zone. A sampling error of 5% and a confidence level of 95% were considered; these afforded a sample of 378 units. Final choice of the subjects was based on a random pathway method. Data collection was accomplished with a personal interview using a 31-item questionnaire and analytical screening (AP and GGT). The field work was carried out over a one-year period. The data were input onto a calculation sheet for analysis and epidemiological interpretation. Finally, clinico-radiological confirmation of the cases deemed positive in the screening was accomplished. The prevalence of PBD in the zone studied is 5.7% (95% CI: 4.5-6.9). The highest percentage of patients lies within the age group between 70-79 years; most of these patients were women. The mean residence time in the zone was 66 years. According to the findings, this geographic zone has a high prevalence of PBD

We examined the prevalence of PDB in Italy from radiological, scintigraphic, and biochemical surveys in two Italian towns. Prevalence rates varied from 0.7% to 2.4%, were higher in males than in females, and slightly differed between the two towns. Unlike previous studies in populations of British descent, no secular trend for a decreasing prevalence emerged. Clinical, radiological, and necropsy data from different countries suggested pronounced geographical variations in the prevalence of Paget's disease of bone (PDB). Despite the impact of the disease on the population, there are limited data on the prevalence of PDB in Italy. The objective of this study was to estimate the prevalence of PDB in the district of Siena (Central Italy) and Turin (Northern Italy) from radiological, biochemical, and scintigraphic surveys. We examined a sample of 1778 consecutive pelvic radiographs performed between 1999 and 2000 at the Hospital Radiology Unit in Siena and 6609 pelvic radiographs performed in 1986-1987, 1992-1993, and 1999-2002 from the Radiology Department of Molinette Hospital in Turin. In Siena, 7906 consecutive (99m)TC-MDP bone scans performed over a 4-year period (January 2000 to May 2004) were also screened for the presence of PDB, and the prevalence of elevated alkaline phosphatase (ALP) levels (>300 UI/liter) was estimated from 7449 computerized medical records over a 3-year period (January 2000 to February 2003). The finding of PDB on the pelvic radiograph and bone scan was based on standardized radiological criteria. At the end of the radiological surveys, 16/1778 pelvic PDB cases (8 males and 8 females) were observed in Siena and 41/6609 (27 males and 14 females) in Turin. The crude prevalence of the disease was 0.89% in Siena and 0.62% in Turin. Given that pelvic involvement is commonly described in 60-90% of PDB patients, the estimated overall prevalence of PDB ranged from 1.0% to 1.5% in Siena and from 0.7% to 1.0% in Turin. No decrease in the prevalence

Sawtooth events and O+ in the plasma sheet and boundary layer: CME- and SIR-driven events

The role of ionospheric ions in sawtooth events is an open question. Simulations[1,2,3] suggest that O+ from the ionosphere produces a feedback mechanism for driving sawtooth events. However, observational evidence[4,5] suggest that the presence of O+ in the plasma sheet is neither necessary nor sufficient. In this study we investigate whether the solar wind driver of the geomagnetic storm has an effect on the result. Building on an earlier study[4] that used events for which Cluster data is available in the plasma sheet and boundary layer, we perform a superposed epoch analysis for coronal mass ejection (CME) driven storms and streaming interaction region (SIR) driven storms separately, to investigate the hypothesis that ionospheric O+ is an important contributor for CME-driven storms but not SIR-driven storms[2].

Dynamical Analysis of SIR Epidemic Models with Distributed Delay

Directory of Open Access Journals (Sweden)

Wencai Zhao

2013-01-01

Full Text Available SIR epidemic models with distributed delay are proposed. Firstly, the dynamical behaviors of the model without vaccination are studied. Using the Jacobian matrix, the stability of the equilibrium points of the system without vaccination is analyzed. The basic reproduction number R is got. In order to study the important role of vaccination to prevent diseases, the model with distributed delay under impulsive vaccination is formulated. And the sufficient conditions of globally asymptotic stability of “infection-free” periodic solution and the permanence of the model are obtained by using Floquet’s theorem, small-amplitude perturbation skills, and comparison theorem. Lastly, numerical simulation is presented to illustrate our main conclusions that vaccination has significant effects on the dynamical behaviors of the model. The results can provide effective tactic basis for the practical infectious disease prevention.

Extracorporeal membrane oxygenation (ECMO) is a life-saving support system used in neonates and young children with severe cardiorespiratory failure. Although ECMO has reduced mortality in these critically ill patients, almost all patients treated with ECMO develop a systemic inflammatory response syndrome (SIRS) characterized by a 'cytokine storm', leukocyte activation, and multisystem organ dysfunction. We used a neonatal porcine model of ECMO to investigate whether rising plasma concentrations of inflammatory cytokines during ECMO reflect de novo synthesis of these mediators in inflamed tissues, and therefore, can be used to assess the severity of ECMO-related SIRS. Previously healthy piglets (3-week-old) were subjected to venoarterial ECMO for up to 8 h. SIRS was assessed by histopathological analysis, measurement of neutrophil activation (flow cytometry), plasma cytokine concentrations (enzyme immunoassays), and tissue expression of inflammatory genes (PCR/western blots). Mast cell degranulation was investigated by measurement of plasma tryptase activity. Porcine neonatal ECMO was associated with systemic inflammatory changes similar to those seen in human neonates. Tumor necrosis factor-alpha (TNF-alpha) and interleukin-8 (IL-8) concentrations rose rapidly during the first 2 h of ECMO, faster than the tissue expression of these cytokines. ECMO was associated with increased plasma mast cell tryptase activity, indicating that increased plasma concentrations of inflammatory cytokines during ECMO may result from mast cell degranulation and associated release of preformed cytokines stored in mast cells. TNF-alpha and IL-8 concentrations rose faster in plasma than in the peripheral tissues during ECMO, indicating that rising plasma levels of these cytokines immediately after the initiation of ECMO may not reflect increasing tissue synthesis of these cytokines. Mobilization of preformed cellular stores of inflammatory cytokines such as in mucosal mast cells may have

Late-Eighteenth-Century Precipitation Reconstructions from James Madison's Montpelier Plantation.

This study presents two independent reconstructions of precipitation from James Madison's Montpelier plantation at the end of the eighteenth century. The first is transcribed directly from meteorological diaries recorded by the Madison family for 17 years and reflects the scientific interests of James Madison and Thomas Jefferson. In his most active period as a scientist, Madison assisted Jefferson by observing the climate and fauna in Virginia to counter the contemporary scientific view that the humid, cold climate of the New World decreased the size and number of its species. The second reconstruction is generated using tree rings from a forest in the Montpelier plantation and connects Madison's era to the modern instrumental precipitation record. These trees provide a significant reconstruction of both early summer and prior fall precipitation. Comparison of the dendroclimatic and diary reconstructions suggests a delay in the seasonality of precipitation from Madison's era to the mid-twentieth century. Furthermore, the dendroclimatic reconstructions of early summer and prior fall precipitation appear to track this shift in seasonality.

2003-01-01

Extramammary Paget's disease (EMPD) is a rare clinical entity and can be associated with other malignancies. We analyzed our experience for prognosis and impact of therapy on outcomes. We conducted a retrospective review of all patients (n = 33) with EMPD treated at a tertiary care center from 1971 to 1998. Pathologic features of EMPD, concurrent secondary malignancies, and the effect of operations on recurrence were analyzed. Overall survival was compared with that of the general population. Male-to-female ratio was 4:29, and median age was 70 years. Median followup was 68 months, and no patient died from EMPD. The lesion was predominantly found on the vulva (76%). Patch-like, nonconfluent growth was present in 45% of patients, and no patient had pathologic lymph nodes. The most common signs and symptoms were irritation or pruritus (73%) and rash (61%). The presence of patches, invasive tumor growth, or a second malignancy were significantly associated with a higher recurrence rate. The type of operation, either local excision or hemivulvectomy, was not related to the time to recurrence. Complete gross resection was achieved in 94% of cases. Fifty-six percent of patients had microscopically positive margin and this correlated with a significantly higher recurrence rate (p = 0.002). The tumor recurred clinically in 14 of 33 patients (42%) after a median of 152 months (range 5 to 209 months). In those patients, between one and six reexcisions were performed. In 14 of 33 patients with EMPD (42%), 16 concurrent secondary malignancies were found. Overall survival rates for EMPD patients were similar to those of the general population. EMPD is an infrequently diagnosed disease that is preferably managed with complete local excision and reexcisions if needed. A thorough search for frequently occurring secondary malignancies might be beneficial to provide the best outcomes for these patients. Copyright 2003 by the American College of Surgeons

By the mid-19th century about 200,000 miners were employed in a UK coal mining industry still growing with the advances of the Industrial Revolution. Coal miners were long known to suffer poor health but the link to inhaling dust in the mines had not been made. In 1813 George Pearson was the first to suggest that darkening of lungs seen in normal individuals as they aged was caused by inhaled soot from burning oil, candles and coal, which were the common domestic sources of heat and light. In 1831 Dr James Craufurd Gregory first described black pigmentation and disease in the lungs of a deceased coal miner and linked this to pulmonary accumulation of coal mine dust. Gregory hypothesised that the black material seen at autopsy in the collier's lungs was inhaled coal dust and this was confirmed by chemical analysis carried out by Professor Sir Robert Christison. Gregory suggested that coal dust was the cause of the disease and warned physicians in mining areas to be vigilant for the disease. This first description of what came to be known as 'coal worker's pneumoconiosis' sparked a remarkable intellectual effort by physicians in Scotland, culminating in a large body of published work that led to the first understandings of this disease and its link to coalblackened lungs. This paper sets out the history of the role of Scottish physicians in gaining this understanding of coal worker's pneumoconiosis. It describes Gregory's case and the lung - recently discovered in the pathology collection of the Surgeons' Hall Museums, Edinburgh, where it has lain unnoticed for over 180 years - on which Gregory based his landmark paper.

Although the biological roles of many members of the sirtuin family of lysine deacetylases have been well characterized, a broader understanding of their role in biology is limited by the challenges in identifying new substrates. We present here an in vitro method that combines biotinylation and mass spectrometry (MS) to identify substrates deacetylated by sirtuins. The method permits labeling of deacetylated residues with amine-reactive biotin on the ε-nitrogen of lysine. The biotin can be utilized to purify the substrate and identify the deacetylated lysine by MS. The biotinyl-lysine method was used to compare deacetylation of chemically acetylated histones by the yeast sirtuins, Sir2 and Hst2. Intriguingly, Sir2 preferentially deacetylates histone H3 lysine 79 as compared to Hst2. Although acetylation of K79 was not previously reported in Saccharomyces cerevisiae, we demonstrate that a minor population of this residue is indeed acetylated in vivo and show that Sir2, and not Hst2, regulates the acetylation state of H3 lysine 79. The in vitro biotinyl-lysine method combined with chemical acetylation made it possible to identify this previously unknown, low-abundance histone acetyl modification in vivo. This method has further potential to identify novel sirtuin deacetylation substrates in whole cell extracts, enabling large-scale screens for new deacetylase substrates.

Mercury at the Oat Hill Extension Mine and James Creek, Napa County, California: Tailings, Sediment, Water, and Biota, 2003-2004

Executive Summary The Oat Hill Extension (OHE) Mine is one of several mercury mines located in the James Creek/Pope Creek watershed that produced mercury from the 1870's until 1944 (U.S. Bureau of Mines, 1965). The OHE Mine developed veins and mineralized fault zones hosted in sandstone that extended eastward from the Oat Hill Mine. Waste material from the Oat Hill Mine was reprocessed at the OHE Mine using gravity separation methods to obtain cinnabar concentrates that were processed in a retort. The U.S. Bureau of Land Management requested that the U.S. Geological Survey measure and characterize mercury and other chemical constituents that are potentially relevant to ecological impairment of biota in tailings, sediment, and water at the OHE Mine and in the tributaries of James Creek that drain the mine area (termed Drainage A and B) (Figs. 1 and 2). This report summarizes such data obtained from sampling of tailings and sediments at the OHE on October 17, 2003; water, sediment, and biota from James Creek on May 20, 2004; and biota on October 29, 2004. These data are interpreted to provide a preliminary assessment of the potential ecological impact of the mine on the James Creek watershed. The mine tailings are unusual in that they have not been roasted and contain relatively high concentrations of mercury (400 to 1200 ppm) compared to unroasted waste rock at other mines. These tailings have contaminated a tributary to James Creek with mercury primarily by erosion, on the basis of higher concentration of mercury (780 ng/L) measured in unfiltered (total mercury, HgT) spring water flowing from the OHE to James Creek compared to 5 to 14 ng/L HgT measured in James Creek itself. Tailing piles (presumably from past Oat Hill mine dumping) near the USBLM property boundary and upstream of the main OHE mine drainage channel (Drainage A; Fig. 2) also likely emit mercury, on the basis of their mercury composition (930 to 1200 ppm). The OHE spring water is likely an

Cai, Yongli; Kang, Yun; Banerjee, Malay; Wang, Weiming

2015-12-01

In this paper, we extend a classical SIRS epidemic model with the infectious forces under intervention strategies from a deterministic framework to a stochastic differential equation (SDE) one through introducing random fluctuations. The value of our study lies in two aspects. Mathematically, by using the Markov semigroups theory, we prove that the reproduction number R0S can be used to govern the stochastic dynamics of SDE model. If R0S 1, under mild extra conditions, it has an endemic stationary distribution which leads to the stochastical persistence of the disease. Epidemiologically, we find that random fluctuations can suppress disease outbreak, which can provide us some useful control strategies to regulate disease dynamics.

Recent studies have demonstrated podoplanin expression in several tumors, which has been associated with lymph node metastasis and poor prognosis. Podoplanin expression in peritumoral cells such as cancer-associated fibroblasts also correlates with tumor progression in several cancers. However, podoplanin expression and its association with extramammary Paget's disease (EMPD) remain unclear. In this study, we examined whether the presence of podoplanin expression in tumor cells or peritumoral basal keratinocytes correlated with aggressive behavior in patients with EMPD and investigated the mechanisms of podoplanin-mediated tumor invasion in this disorder. Skin samples of 37 patients with EMPD were investigated by immunohistochemical analysis. The functions of podoplanin in keratinocytes were examined in vitro by RT-PCR and with invadopodia gelatin-degradation assays using HaCaT cells. Podoplanin was not identified in tumor cells in all cases. Podoplanin expression in peritumoral basal keratinocytes was observed in 25 patients (67.6%). In in situ EMPD, 50% of cases (9 in 18) exhibited podoplanin-positive keratinocytes, whereas 84.2% (16 in 19) demonstrated positive staining in invasive EMPD (P<0.05). Podoplanin expression in peritumoral keratinocytes was also associated with tumor thickness (P<0.005). By immunohistochemical analysis, podoplanin-positive peritumoral keratinocytes were found to be negative for E-cadherin, one of the major adhesion molecules of keratinocytes, which might contribute to tumor invasion into the dermis through a crack in the basal cell layer induced by down-regulation of cell adhesion therein. We further found that podoplanin-positive keratinocytes exhibited invadopodia, which are thought to function in the migration of cancer cells through tissue barriers, indicating that podoplanin-positive peritumoral basal keratinocytes might assist tumor invasion by degrading the extracellular matrix. The presence of podoplanin expression in

Genes ycfR, sirA and yigG contribute to the surface attachment of Salmonella enterica Typhimurium and Saintpaul to fresh produce.

Directory of Open Access Journals (Sweden)

Joelle K Salazar

Full Text Available Salmonella enterica is a frequent contaminant of minimally-processed fresh produce linked to major foodborne disease outbreaks. The molecular mechanisms underlying the association of this enteric pathogen with fresh produce remain largely unexplored. In our recent study, we showed that the expression of a putative stress regulatory gene, ycfR, was significantly induced in S. enterica upon exposure to chlorine treatment, a common industrial practice for washing and decontaminating fresh produce during minimal processing. Two additional genes, sirA involved in S. enterica biofilm formation and yigG of unknown function, were also found to be differentially regulated under chlorine stress. To further characterize the roles of ycfR, sirA, and yigG in S. enterica attachment and survival on fresh produce, we constructed in-frame deletions of all three genes in two different S. enterica serovars, Typhimurium and Saintpaul, which have been implicated in previous disease outbreaks linked to fresh produce. Bacterial attachment to glass and polystyrene microtiter plates, cell aggregation and hydrophobicity, chlorine resistance, and surface attachment to intact spinach leaf and grape tomato were compared among wild-type strains, single-gene deletion mutants, and their respective complementation mutants. The results showed that deletions of ycfR, sirA, and yigG reduced bacterial attachment to glass and polystyrene as well as fresh produce surface with or without chlorine treatment in both Typhimurium and Saintpaul. Deletion of ycfR in Typhimurium significantly reduced bacterial chlorine resistance and the attachment to the plant surfaces after chlorinated water washes. Deletions of ycfR in Typhimurium and yigG in Saintpaul resulted in significant increase in cell aggregation. Our findings suggest that ycfR, sirA, and yigG collectively contribute to S. enterica surface attachment and survival during post-harvest minimal processing of fresh produce.

Genetic differentiation of spring-spawning and fall-spawning male Atlantic sturgeon in the James River, Virginia.

Directory of Open Access Journals (Sweden)

Matthew T Balazik

Full Text Available Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus, Acipenseridae populations are currently at severely depleted levels due to historic overfishing, habitat loss, and pollution. The importance of biologically correct stock structure for effective conservation and management efforts is well known. Recent improvements in our understanding of Atlantic sturgeon migrations, movement, and the occurrence of putative dual spawning groups leads to questions regarding the true stock structure of this endangered species. In the James River, VA specifically, captures of spawning Atlantic sturgeon and accompanying telemetry data suggest there are two discrete spawning groups of Atlantic sturgeon. The two putative spawning groups were genetically evaluated using a powerful microsatellite marker suite to determine if they are genetically distinct. Specifically, this study evaluates the genetic structure, characterizes the genetic diversity, estimates effective population size, and measures inbreeding of Atlantic sturgeon in the James River. The results indicate that fall and spring spawning James River Atlantic sturgeon groups are genetically distinct (overall FST = 0.048, F'ST = 0.181 with little admixture between the groups. The observed levels of genetic diversity and effective population sizes along with the lack of detected inbreeding all indicated that the James River has two genetically healthy populations of Atlantic sturgeon. The study also demonstrates that samples from adult Atlantic sturgeon, with proper sample selection criteria, can be informative when creating reference population databases. The presence of two genetically-distinct spawning groups of Atlantic sturgeon within the James River raises concerns about the current genetic assignment used by managers. Other nearby rivers may also have dual spawning groups that either are not accounted for or are pooled in reference databases. Our results represent the second documentation of genetically

In this paper, an SIR model with birth and death on complex networks is analyzed, where infected individuals are divided into m groups according to their infection and contact between human is treated as a scale-free social network. We obtain the basic reproduction number R0 as well as the effects of various immunization schemes. The results indicate that the disease-free equilibrium is locally and globally asymptotically stable in some conditions, otherwise disease-free equilibrium is unstable and exists an unique endemic equilibrium that is globally asymptotically stable. Our theoretical results are confirmed by numerical simulations and a promising way for infectious diseases control is suggested.

Besides a pleasant author of best sellers, Sir Arthur Conan Doyle was a medical doctor, writing excellent short stories about the exercise of his profession in England. However, even he mentions The British Medical Journal and The Lancet in the Sherlock Holmes's stories, when in the plot introduces infectious diseases, Conan Doyle ignores important discoveries in the field of tetanus. Anyway, the appearing of infectious diseases in the adventures of the detective are rare: one mention of tetanus, another of leprosy and- the most analyzed in medical literature a case of murder by inoculation of bacteria, probably the agent of melioidosis. Also he makes his hero discovers the toxic actions of a medusa and a transplant of solid organ. Little for a physician and less for an author who also wrote science fiction: it seems that the history of the great medical discoveries at the end of nineteenth century and beginning of the twentieth has passed by his side.., and he just couldn't see it.

2015-03-01

Full Text Available This research paper proposes an analytical approach to the study of the phenomenon of the film-induced pilgrimage tourism, along one of the most historical and relevant European cultural route: the Way of St. James or Camino de Santiago.In the present study, and in order to point out the relation between film broadcast and film-induced tourism, we combine the review of the Jacobean cinema with the statistical analysis of the pilgrims arrived to Santiago de Compostela during the last decade. So, our main aim is to analyse the repercussion of the Jacobean Cinema in the attractiveness of the Way of St. James as tourism destination. We take into consideration the role of the film producers and we also ponder on the marketing policies of the Autonomous Community, which are aimed at promoting the pilgrim’s routes, the Cathedral and the city of Santiago de Compostela. The cinema has played a less important role until now, in comparison with the impact of travel guides and the Jacobean literature, but it is increasing its impact in the international tourism markets. Recently, the American film The Way can be considered to be the first promoter of the film-induced tourism, because the arrivals of pilgrims from USA have been increased after the broadcast of this film since 2010.

Only a few myxobacteria are known to date which are classified as marine due to their salt-dependency. In this study, the salt tolerance mechanism of these bacteria was investigated. Therefore, a growth medium was designed, in which the mutated Escherichia coli strain BKA13 served as sole food source for the predatory, heterotrophic myxobacteria. This enabled measurement of the osmolytes without any background and revealed that the closely related strains Enhygromyxa salina SWB007 and Plesiocystis pacifica SIR-1 developed different strategies to handle salt stress. P. pacifica SIR-1, which was grown between 1-4 % NaCl, relies solely on the accumulation of amino acids, while E. salina SWB007, which was grown between 0.5-3 % NaCl, employs, beside betaine, hydroxyectoine as the major compatible solute. In accordance with this analysis, only in the latter strain a gene locus was identified which codes for genes corresponding to the biosynthesis of betaine, ectoine, and hydroxyectoine.

[Dr James Lovelock and story about GAIA hypothesis].

Science.gov (United States)

Gajić, Vladimir

2011-01-01

Gaia is the Anglo-Saxon term for the Hellenic term Gea or Ge, which means Earth. The GAIA hypothesis was launched almost 40 years ago by the famous chemist James Lovelock, who was engaged by the National Aeronautics and Space Administration (NASA) to create a sensitive instrument for searching forms of extraterrestrial life on other planets. Then he published the book The ages of GAIA, which perturbed the world's scientific public of those days. Lovelock struck upon this idea in the late sixties of the past century, during the space race with Russians, when he was hired hy the National Aeronautics and Space Administration to conduct a series of experiments to find and explore life forms on the planet Mars. Experiments executed by the American module Viking failed to trace any life form, as Lovelock had predicted. He called it a dead equilibrium. Then he turned to Earth, whose perspective is totally different from its first neighbors. Venus and Mars, and is far from a dead equilibrium. DAISYWORLD: In this hypothesis. Lovelock represents Earth as one living, giant super organism, composed of all living creatures and its material environnent. In that super organisnm, the level of oxygen, weather conditions, ocean salinity and so on are under constant influence of physical, chemical and biological processes, which provide the existence for such life forms on Earth. Dr James Lovelock represents a pioneer of climatology, and his hypothesis gives a unique insight into the correlation of dynamic processes on our planet, no matter whether they are of physical or biological nature.

A mixed SIR-SIS model to contain a virus spreading through networks with two degrees

Science.gov (United States)

Essouifi, Mohamed; Achahbar, Abdelfattah

Due to the fact that the “nodes” and “links” of real networks are heterogeneous, to model computer viruses prevalence throughout the Internet, we borrow the idea of the reduced scale free network which was introduced recently. The purpose of this paper is to extend the previous deterministic two subchains of Susceptible-Infected-Susceptible (SIS) model into a mixed Susceptible-Infected-Recovered and Susceptible-Infected-Susceptible (SIR-SIS) model to contain the computer virus spreading over networks with two degrees. Moreover, we develop its stochastic counterpart. Due to the high protection and security taken for hubs class, we suggest to treat it by using SIR epidemic model rather than the SIS one. The analytical study reveals that the proposed model admits a stable viral equilibrium. Thus, it is shown numerically that the mean dynamic behavior of the stochastic model is in agreement with the deterministic one. Unlike the infection densities i2 and i which both tend to a viral equilibrium for both approaches as in the previous study, i1 tends to the virus-free equilibrium. Furthermore, since a proportion of infectives are recovered, the global infection density i is minimized. Therefore, the permanent presence of viruses in the network due to the lower-degree nodes class. Many suggestions are put forward for containing viruses propagation and minimizing their damages.

Using administrative codes and minimal physiologic and laboratory data, we sought a high-specificity identification strategy for patients whose sepsis initially appeared during their ICU stay. We studied all patients discharged from an academic hospital between September 1, 2013 and October 31, 2014. Administrative codes and minimal physiologic and laboratory criteria were used to identify patients at high risk of developing the onset of sepsis in the ICU. Two clinicians then independently reviewed the patient record to verify that the screened-in patients appeared to become septic during their ICU admission. Clinical chart review verified sepsis in 437/466 ICU stays (93.8%). Of these 437 encounters, only 151 (34.6%) were admitted to the ICU with neither SIRS nor evidence of infection and therefore appeared to become septic during their ICU stay. Selected administrative codes coupled to SIRS criteria and applied to patients admitted to ICU can yield up to 94% authentic sepsis patients. However, only 1/3 of patients thus identified appeared to become septic during their ICU stay. Studies that depend on high-intensity monitoring for description of the time course of sepsis require clinician review and verification that sepsis initially appeared during the monitoring period.

Threshold Dynamics in Stochastic SIRS Epidemic Models with Nonlinear Incidence and Vaccination

Directory of Open Access Journals (Sweden)

Lei Wang

2017-01-01

Full Text Available In this paper, the dynamical behaviors for a stochastic SIRS epidemic model with nonlinear incidence and vaccination are investigated. In the models, the disease transmission coefficient and the removal rates are all affected by noise. Some new basic properties of the models are found. Applying these properties, we establish a series of new threshold conditions on the stochastically exponential extinction, stochastic persistence, and permanence in the mean of the disease with probability one for the models. Furthermore, we obtain a sufficient condition on the existence of unique stationary distribution for the model. Finally, a series of numerical examples are introduced to illustrate our main theoretical results and some conjectures are further proposed.

James Hillman: Toward a poetic psychology.

Science.gov (United States)

Avens, R

1980-09-01

InThe Dream and the Underworld James Hillman continues to deepen and to refine Jung's recovery of the spontaneous image-making of the soul. Hillman's contribution lies in his "imaginai reduction"-relating of images to their archetypal background in Greek mythology. Myth is seen as the maker of the psyche, and, in turn, the soul-making ispoesis-a return to the imaginal and poetic basis of consciousness. Dreams, understood poetically, are neither messages to be deciphered and used for the benefit of the rational ego (Freud) nor compensatory to the ego (Jung); they are complete in themselves and must be allowed to speak for themselves. Hillman also sees dreams as initiations into the underworld of death-the other side of life where our imaginal substance is unobstructed by the literal and dualistic standpoints of the dayworld.

On pulse vaccine strategy in a periodic stochastic SIR epidemic model

International Nuclear Information System (INIS)

Wang, Fengyan; Wang, Xiaoyi; Zhang, Shuwen; Ding, Changming

2014-01-01

A periodic stochastic SIR epidemic model with pulse vaccination is studied. The system has global positive solutions and under some conditions it admits a unique positive periodic disease-free solution, which is globally exponentially stable in mean square. The mathematical expectation and variance of the positive periodic solution are obtained. Two threshold parameters R 1 and R 2 (R 1 >R 2 ) are identified; if R 1 <1, the susceptible will be persistent in the mean and the disease will go to extinction; if R 2 >1, the susceptible and the disease will be weakly persistent in the mean. We show that by repeatedly vaccinating the susceptible population in series of pulses, it is possible to eradicate the infective from the entire model population in the random environment

Granular statistical mechanics - Building on the legacy of Sir Sam Edwards

Science.gov (United States)

Blumenfeld, Raphael

When Sir Sam Edwards laid down the foundations for the statistical mechanics of jammed granular materials he opened a new field in soft condensed matter and many followed. In this presentation we review briefly the Edwards formalism and some of its less discussed consequences. We point out that the formalism is useful for other classes of systems - cellular and porous materials. A certain shortcoming of the original formalism is then discussed and a modification to overcome it is proposed. Finally, a derivation of an equation of state with the new formalism is presented; the equation of state is analogous to the PVT relation for thermal gases, relating the volume, the boundary stress and measures of the structural and stress fluctuations.

Development of Immunopathobiogenesis on SIRS-Sepsis

A Guntur Hermawan

2009-04-01

Full Text Available Over the past decade, sepsis has been diagnosed according to consensus guidelines established in 1991 as an infection in addition to the symptoms of systemic inflammatory response syndrome (SIRS. In addition to the previous criteria, the 2001 conference added several new diagnostic criteria for sepsis. Of particular interest was the inclusion of the biomarkers procalcitonin (PCT and C-reactive protein (CRP, despite the overall conclusion that it was premature to use biomarkers for sepsis diagnosis. The primary recommendation of the panel was the implementation of the Predisposition, insult Infection, Response, and Organ dysfunction (PIRO.The immune system has traditionally been devided into innate and adaptive components, each of which has a different role and function in defending the host against infectious agents. Stimulation of different TLRs induces distinct patterns of gene expression, which not only leads to the activation of innate immunity but also increasing evidence supports an additional critical role for TLRs in orchestrating the development of adaptive immune responses. The superantigens are able to induce toxic shock syndrome and can sometimes cause multiple organ failure via adaptive immune system. The superantigenic activity of the bacterial exotoxins can be attributed to their ability to cross-link major histocompatibility complex class II molecules on antigen-presenting cells outside the peptide groove with T-cell receptors to form a trimolecular complex. This trimolecular interaction leads to uncontrolled release of a number of proinflammatory cytokines. Proinflammatory cytokines especially IFN-γ and TNF-α, the key cytokines causing toxic shock syndrome. KEYWORDS: sepsis, innate immunity, adaptive.

There is no widely accepted assessment tool or common language used by clinicians caring for patients with facial palsy, making exchange of information challenging. Standardized photography may represent such a language and is imperative for precise exchange of information and comparison of outcomes in this special patient population. To review the literature to evaluate the use of facial photography in the management of patients with facial palsy and to examine the use of photography in documenting facial nerve function among members of the Sir Charles Bell Society-a group of medical professionals dedicated to care of patients with facial palsy. A literature search was performed to review photographic standards in patients with facial palsy. In addition, a cross-sectional survey of members of the Sir Charles Bell Society was conducted to examine use of medical photography in documenting facial nerve function. The literature search and analysis was performed in August and September 2015, and the survey was conducted in August and September 2013. The literature review searched EMBASE, CINAHL, and MEDLINE databases from inception of each database through September 2015. Additional studies were identified by scanning references from relevant studies. Only English-language articles were eligible for inclusion. Articles that discussed patients with facial palsy and outlined photographic guidelines for this patient population were included in the study. The survey was disseminated to the Sir Charles Bell Society members in electronic form. It consisted of 10 questions related to facial grading scales, patient-reported outcome measures, other psychological assessment tools, and photographic and videographic recordings. In total, 393 articles were identified in the literature search, 7 of which fit the inclusion criteria. Six of the 7 articles discussed or proposed views specific to patients with facial palsy. However, none of the articles specifically focused on

The naturally occurring anthraquinone emodin has been serving primarily as an anti-bacterial and anti-inflammatory agent. However, little is known about its potential on anti-aging. This investigation examined the effect of emodin on lifespan and focused on its physiological molecular mechanisms in vivo. Using Caenorhabditis elegans (C. elegans) as an animal model, we found emodin could extend lifespan of worms and improve their antioxidant capacity. Our mechanistic studies revealed that emodin might function via insulin/IGF-1 signaling (IIS) pathway involving, specifically the core transcription factor DAF-16. Quantitative RT-PCR results illustrated that emodin up-regulated transcription of DAF-16 target genes which express antioxidants to promote antioxidant capacity and lifespan of worms. In addition, attenuated effect in sir-2.1 mutants suggests that emodin likely functioned in a SIR-2.1-dependent manner. Our study uncovers a novel role of emodin in prolonging lifespan and supports the understanding of emodin being a beneficial dietary supplement.

Nationalism in James Joyce's Ulysses

Bahee Hadaegh

2016-03-01

Full Text Available In the present article, the role of nationalism and postcolonialism in James Joyce's Ulysses is explored. The novel is used to reveal the political and postcolonial layers of Joyce's work and represent how colonization works through politics. This helps the readers to realize more about political Joyce and to apprehend his political views as a fresh reading of his oeuvre. The significance of this article is to depict how an author from a colonized society is influenced by the colonizing forces and cultural invasions and to scrutinize the very psychology of a colonized nation. This task is done through Attridge and Howes's methodology as the theoretical framework containing key roles in analyzing the main discussion. Through analyzing Ulysses, this article clearly shows that Joyce was a part of nationalistic movements such as the Irish Revival; however he had major conflicts with some individuals and movements that claimed to be nationalists. Therefore, Joyce is concluded to be a 'semicolonial' writer who has his own specific mode of nationalism.

Berlinski, David

2000-01-01

Sir Isaac Newton, creator of the first and perhaps most important scientific theory, is a giant of the scientific era. Despite this, he has remained inaccessible to most modern readers, indisputably great but undeniably remote. In this witty, engaging, and often moving examination of Newton's life, David Berlinski recovers the man behind the mathematical breakthroughs. The story carries the reader from Newton's unremarkable childhood to his awkward undergraduate days at Cambridge through the astonishing year in which, working alone, he laid the foundation for his system of the world, his Principia Mathematica, and to the subsequent monumental feuds that poisoned his soul and wearied his supporters. An edifying appreciation of Newton's greatest accomplishment, Newton's Gift is also a touching celebration of a transcendent man.

In this paper, the correlation coefficients between nodes in states are used as dynamic variables, and we construct SIR epidemic dynamic models with correlation coefficients by using the pair approximation method in static networks and dynamic networks, respectively. Considering the clustering coefficient of the network, we analytically investigate the existence and the local asymptotic stability of each equilibrium of these models and derive threshold values for the prevalence of diseases. Additionally, we obtain two equivalent epidemic thresholds in dynamic networks, which are compared with the results of the mean field equations. Copyright © 2018 Elsevier Ltd. All rights reserved.

Optimizing Real-Time Vaccine Allocation in a Stochastic SIR Model.

Directory of Open Access Journals (Sweden)

Chantal Nguyen

Full Text Available Real-time vaccination following an outbreak can effectively mitigate the damage caused by an infectious disease. However, in many cases, available resources are insufficient to vaccinate the entire at-risk population, logistics result in delayed vaccine deployment, and the interaction between members of different cities facilitates a wide spatial spread of infection. Limited vaccine, time delays, and interaction (or coupling of cities lead to tradeoffs that impact the overall magnitude of the epidemic. These tradeoffs mandate investigation of optimal strategies that minimize the severity of the epidemic by prioritizing allocation of vaccine to specific subpopulations. We use an SIR model to describe the disease dynamics of an epidemic which breaks out in one city and spreads to another. We solve a master equation to determine the resulting probability distribution of the final epidemic size. We then identify tradeoffs between vaccine, time delay, and coupling, and we determine the optimal vaccination protocols resulting from these tradeoffs.

Shuttle imaging radar-A (SIR-A) data analysis. [geology of the Ozark Plateau of southern Missouri, land use in western Illinois, and vegetation types at Koonamore Station, Australia

Science.gov (United States)

Arvidson, R. E.

1983-01-01

The utility of shuttle imaging radar (SIR-A) data was evaluated in several geological and environmental contexts. For the Ozark Plateau of southern Missouri, SIR-A data were of little use in mapping structural features, because of generally uniform returns. For western Illinois, little was to be gained in terms of identifying land use categories by examining differences between overlapping passes. For southern Australia (Koonamore Station), information ion vegetation types that was not obtainable from LANDSAT MSS data alone was obtained. Specifically, high SIR-A returns in the Australian site were found to correlate with locations where shrubs increase surface roughness appreciably. The Australian study site results demonstrate the synergy of acquiring spectral reflectance and radar data over the same location and time. Such data are especially important in that region, since grazing animals have substantially altered and are continuing to alter the distribution of shrublands, grasslands, and soil exposures. Periodic, synoptic acquisition of MSS and SAR data would be of use in monitoring the dynamics of land-cover change in this environment.

Religious Experience and its Essentialism in William James and Ghazzali’s Views

Directory of Open Access Journals (Sweden)

Ahmad Ebadi

2016-03-01

Full Text Available Abstract Religious experience is an approach to which Western thinkers are considered pioneers among whom Schleiermacher is the most prominent. "The essentialism of religious experience" is one of the several approaches that have been adopted in the case of religious experience. Accordingly, the religion that has sides and various dimensions has been reduced to a religious experience and the religious experience is introduced as the essence of religion. What is presented in this article is a comparative study of the essence of religious experience from the perspective of William James and Ghazzāli. Although mystical experience has a different structure form the religious experience and Ghazali as well as other Muslim philosophers and mystics paid more attention to the way of mystical experience, in the works of Ghazali there are also a traces of religious experience and hence, they are adaptable to some aspects of religious experience offered by William James. William James defines the religion “as the feelings, acts, and experiences that can occur for every individual in their solitudes and he believes that feeling is the essential pillar of religion and inherently reinforces it”. Religious experience is the essence of religion and it means that-the truth of the faith is the same as feelings and emotions that emerge from rational reflections on concrete reality as such, and other spiritual, transcendental, mystical and psychological actions are the consequences of these experiences. On the other hand, in the Muslim world, Al-Ghazzali believes that: The ultimate and holy aim of religion is the perception and experience of ultimate truth that can be achieved through good deeds, worship, asceticism and piety. This article tries to find similarities and differences in essence of religious experience of the two thinkers, because it is only in the theory of the essentialism of religious experience that the similarities and differences of

This article focuses on the 20-year gap between Charles S. Peirce's classic proposal of pragmatism in 1877-1878 and William James's equally classic call for pragmatism in 1898. It fills the gap by reviewing relevant developments in the work of Peirce and James and by introducing G. Stanley Hall, for the first time, as a figure in the history of pragmatism. In treating Hall and pragmatism, the article reveals a previously unnoted relation between the early history of pragmatism and the early history of the "new psychology" that Hall helped to pioneer.

Sir John Adams: his legacy to the world of particle accelerators

CERN Document Server

Wilson, E J N

2011-01-01

John Adams acquired an unrivalled reputation for his leading part in designing and constructing the Proton Synchrotron (PS) in CERN’s early days. In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the Super Proton Synchrotron (SPS) project to approval and then to direct its construction. By the time of his early death in 1984 he had built the two flagship proton accelerators at CERN and, during the second of his terms as Director-General, he laid the groundwork for the proton–antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? The speaker, who worked many years alongside him, will discuss these questions and speculate on how Sir John Adams might have viewed today’s CERN.

Low sensitivity of qSOFA, SIRS criteria and sepsis definition to identify infected patients at risk of complication in the prehospital setting and at the emergency department triage.

Science.gov (United States)

Tusgul, Selin; Carron, Pierre-Nicolas; Yersin, Bertrand; Calandra, Thierry; Dami, Fabrice

2017-11-03

Sepsis is defined as life-threatening organ dysfunction caused by a host response to infection. The quick SOFA (qSOFA) score has been recently proposed as a new bedside clinical score to identify patients with suspected infection at risk of complication (intensive care unit (ICU) admission, in-hospital mortality). The aim of this study was to measure the sensitivity of the qSOFA score, SIRS criteria and sepsis definitions to identify the most serious sepsis cases in the prehospital setting and at the emergency department (ED) triage. We performed a retrospective study of all patients transported by emergency medical services (EMS) to the Lausanne University Hospital (CHUV) over twelve months. All patients with a suspected or proven infection after the ED workup were included. We retrospectively analysed the sensitivity of the qSOFA score (≥2 criteria), SIRS criteria (≥2 clinical criteria) and sepsis definition (SIRS criteria + one sign of organ dysfunction or hypoperfusion) in the pre-hospital setting and at the ED triage as predictors of ICU admission, ICU stay of ≥3 days and early (i.e. 48 h) mortality. No direct comparison between the three tools was attempted. Among 11,411 patients transported to the University hospital, 886 (7.8%) were included. In the pre-hospital setting, the sensitivity of qSOFA reached 36.3% for ICU admission, 17.4% for ICU stay of three days or more and 68.0% for 48 h mortality. The sensitivity of SIRS criteria reached 68.8% for ICU admission, 74.6% for ICU stay of three days or more and 64.0% for 48 h mortality. The sensitivity of sepsis definition did not reach 60% for any outcome. At ED triage, the sensitivity of qSOFA reached 31.2% for ICU admission, 30.5% for ICU stay of ≥3 days and 60.0% for mortality at 48 h. The sensitivity of SIRS criteria reached 58.8% for ICU admission, 57.6% for ICU stay of ≥3 days 80.0% for mortality at 48 h. The sensitivity of sepsis definition reached 60.0% for 48 h mortality.

A class of SIR epidemic model with generalized nonlinear incidence rate is presented in this paper. Temporary immunity and stochastic perturbation are also considered. The existence and uniqueness of the global positive solution is achieved. Sufficient conditions guaranteeing the extinction and persistence of the epidemic disease are established. Moreover, the threshold behavior is discussed, and the threshold value R0 is obtained. We show that if R0 extinct with probability one, whereas if R0 > 1, then the system remains permanent in the mean.

Judaism in the theology of Sir Isaac Newton

Goldish, Matt

1998-01-01

This book is based on my doctoral dissertation from the Hebrew University of Jerusalem (1996) of the same title. As a master's student, working on an entirely different project, I was well aware that many of Newton's theological manuscripts were located in our own Jewish National and University Library, but I was under the mistaken assumption that scores of highly qualified scholars must be assiduously scouring them and publishing their results. It never occurred to me to look at them at all until, having fmished my master's, I spoke to Professor David Katz at Tel-Aviv University about an idea I had for doctoral research. Professor Katz informed me that the project I had suggested was one which he himself had just fmished, but that I might be interested in working on the famous Newton manuscripts in the context of a project being organized by him, Richard Popkin, James Force, and the late Betty Jo Teeter Dobbs, to study and publish Newton's theological material. I asked him whether he was not sending me into ...

Sir Harold Gillies, born in New Zealand, is widely considered a British icon and the father of modern plastic surgery. This article provides an overview of his life and the circumstances which led to him laying the foundations of plastic surgery in Britain in the early twentieth century. A hand search and review of case notes from the Gillies Archives at Queen Mary's Hospital in Sidcup, UK, where he made history, was conducted. Gillies' ongoing legacy was found to also include his influence on the development of his cousin Sir Archibald McIndoe's work. Gillies was a talented sportsman who engaged in charitable activities. Additionally, he was a gifted teacher, with his hospital attracting many young surgeons from around the world. He was found to have expressed genius in both the design and execution of the art and science of surgery. He incepted reconstructive techniques ranging from the world's first gender reassignment operation to facial reanimation procedures for the treatment of facial paralysis. His operative work on ex-servicemen in need of complex rhinoplasty and in particular the inception of the tubed pedicle flap are depicted.

Extramammary Paget's disease (EMPD) is a rare tumor of the skin characterized by extended irregular subclinical growth and high recurrence rates after surgery. To show that, using three-dimensional (3D) histology in surgical excision, the size of the safety margin can be individually determined and locally adjusted to subclinical growth and to evaluate the course of the disease in 33 patients. The clinical records of 33 patients with primary lesions of EMPD were prospectively documented, retrospectively confirmed, and analyzed. EMPD was found more frequently in women (54.5%). Dermal invasion was found in 21.2%, and regional lymph node metastases were present in one patient; 30.3% of the patients had secondary internal malignancies. In 25 cases examined using 3D histology, a mean surgical margin of 22 mm in asymmetric shape (range 5-65 mm) was achieved, with a recurrence rate of 28%. Surgery with conventional histologic examination had a higher recurrence rate of 62.5% using a mean surgical margin of 19 mm (range 7-40 mm). Subclinical spread of EMPD demonstrated using 3D histology with paraffin sectioning can be large. Three-dimensional histology allows individually defined safety margins to be locally adjusted to subclinical growth and gives low recurrence rates. The authors have indicated no significant interest with commercial supporters. © 2011 by the American Society for Dermatologic Surgery, Inc.

To develop a more concise, user-friendly edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM advisory board is probably already hard at work on the DSM-6, so this study is focused on the DSM-(00)7 edition. We conducted an observational study, using a mixed methods approach to analyse the 50th edition boxset of James Bond experiences. James Bond was selected as a suitably complex subject for the basis of a trial of simplifying the DSM. Researchers' televisions and computers from late January to mid-April in Auckland, New Zealand. Following a review of the 23 James Bond video observations, we identified 32 extreme behaviours exhibited by the subject; these could be aggregated into 13 key domains. A Delphi process identified a cluster of eight behaviours that comprise the Bond Adequacy Disorder (BAD). A novel screening scale was then developed, the Bond Additive Descriptors of Anti-Sociality Scale (BADASS), with a binary diagnostic outcome, BAD v Normality Disorder. We propose that these new diagnoses be adopted as the foundation of the DSM-(00)7. The proposed DSM-(00)7 has benefits for both patients and clinicians. Patients will experience reduced stigma, as most individuals will meet the criteria for Normality Disorder. This parsimonious diagnostic approach will also mean clinicians have more time to focus on patient management.

THE QUEST FOR KNOWLEDGE IN "THE KING JAMES BIBLE"

Directory of Open Access Journals (Sweden)

Ewa Piotrowska-Oberda

2014-10-01

Full Text Available The aim of this article is the quest for knowledge in "The King James Bible" (1611 in terms of quantitative and qualitative research methodology with the application of the statistical analysis tool Antconc. The quest for knowledge with the use of corpus research aims at discussing the Biblical concept of knowledge through the origin, the object of knowledge, its implications and its constant development. Knowledge is often seen as of divine nature, reflected in the soul of man. It is based not only on logical, but also on the spiritual and ethical reasoning. The object of knowledge is light, reflecting the divine nature of knowledge which exceeds the intellect to reach a deeper spiritual human reasoning. In "The King James Bible" (1611 the authors of New Testament consider human knowledge to be imperfect and partial. They emphasize the need for a spiritual man aiming at reaching a complete knowledge. This spiritual development is based on the relationship between knowledge and faith, as well as knowledge and love. For the authors of the books of the New Testament there is no dichotomy between both knowledge and faith and knowledge and love, because faith and love depend on knowledge that originates in the word of God and leads to spiritual development. From this perspective, religious knowledge, love and mercy as well as faith developed through the knowledge of the biblical text leads to the knowledge of God, the enlightening source of ultimate knowledge. Thus, in the spiritual development of man not only the knowledge and faith but also emotional intelligence, which expresses itself through love and charity as the safer guide in all controversial issues, are important.

James Bay air quality study : report on the results of field monitoring in 2007

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-02-08

An air quality study in James Bay was conducted, in order to establish general levels of pollutants in outdoor air in the James Bay area of Victoria, British Columbia. The primary sources of air pollution in the area include light duty and heavy duty vehicle traffic, helicopters, floatplanes, and marine vessels such as cruise ships, passenger ferries, commercial fishing and whale watching boats, and recreation motorboats. Air quality monitoring represented the first phase of the project. The second phase involved a detailed pollutant dispersion model including all emission sources. This report described the use of sampling equipment and the measurement of nitric oxide, nitrogen dioxide, sulfur dioxide, fine particulate matter and contributing sources, and volatile organic compounds, specifically benzene, toluene, ethylbenzene/xylene and naphthalene. Supporting data, including traffic counts, wind speed and direction, precipitation, and cruise ship schedules were collected to assist in the interpretation of the field monitoring results. For each of these pollutants, the report provided responses to several questions, such as defining each pollutant; describing the sources of each pollutant in the James Bay neighbourhood; presenting the results of the field monitoring; discussing the limitations of the monitoring equipment and sampling design; interpreting the results; comparing monitored levels to those measured at other times or locations; and comparing monitored levels to air quality standards or guidelines. Conclusions about each pollutant were presented. It was concluded that phase 2 pollutant dispersion modelling should include estimates of 1-hour, 24-hour, and seasonal average pollutant levels at varying elevations above ground level, with a focus on residential apartment buildings in the study area. 5 tabs., 52 figs., 7 appendices.

Upriver transport of dissolved substances in an estuary and sub-estuary system of the lower James River, Chesapeake Bay

2018-01-01

The water exchange between the James River and the Elizabeth River, an estuary and sub-estuary system in the lower Chesapeake Bay, was investigated using a 3D numerical model. The conservative passive tracers were used to represent the dissolved substances (DS) discharged from the Elizabeth River. The approach enabled us to diagnose the underlying physical processes that control the expansion of the DS, which is representative of potential transport of harmful algae blooms, pollutants from the Elizabeth River to the James River without explicitly simulating biological processes. Model simulations with realistic forcings in 2005, together with a series of processoriented numerical experiments, were conducted to explore the correlations of the transport process and external forcing. Model results show that the upriver transport depends highly on the freshwater discharge on a seasonal scale and maximum upriver transport occurs in summer with a mean transport time ranging from 15-30 days. The southerly/easterly wind, low river discharge, and neap tidal condition all act to strengthen the upriver transport. On the other hand, the northerly/westerly wind, river pulse, water level pulse, and spring tidal condition act to inhibit the upriver transport. Tidal flushing plays an important role in transporting the DS during spring tide, which shortens the travel time in the lower James River. The multivariable regression analysis of volume mean subtidal DS concentration in the mesohaline portion of the James River indicates that DS concentration in the upriver area can be explained and well predicted by the physical forcings (r = 0.858, p = 0.00001).

Mccauley, J. F.; Breed, C. S.; Schaber, G. G.; Mchugh, W. P.; Haynes, C. C.

1986-01-01

The images obtained by the Shuttle Imaging Radar (SIR)-A and -B systems over the southwestern Egypt and northwestern Sudan were coregistered with the Landsat images and the existing maps to aid in extrapolations of the buried paleodrainages ('radar rivers'), first discovered by SIR-A. Field observations explain the radar responses of three types of radar rivers, RR-1 (broad, aggraded valleys filled with alluvium), RR-2 (braided channels inset in the RR-1 valleys), and RR-3 (narrow, long, bedrock-incised channels). A generalized model of the radar rivers, based on field studies and regional geologic relations, shows inferred changes in river regimen since the large valleys were established during the later Paleogene-early Neogene. It is suggested that a former Trans-African master stream system may have flowed from headwaters in the Red Sea Hills southwestward across North Africa, discharging into the Atlantic at the Paleo-Niger delta, prior to the Neogene domal uplifts and building of volcanic edifices across the paths of these ancient watercourses.

Occupational exposure following Yttrium-90 microspheres SIR therapy

Full text of publication follows. Introduction: Selective Internal Radiation Therapy (SIRT) is a promising technique for solid hepatic neoplasms treatment. SIRT consists in implanting radioactive microspheres (RMS) in targeted hepatic lesions via femoral artery. Two RMS-Therapsheres [glass-microspheres/TSR] and Sir-Spheres [resin-spheres/SSR]- are marketed in the European market, both radiolabeled with Yttrium-90. The objective of this study is to assess occupational exposure for nuclear medicine, radiology and clinical staff involved in Y 90 -RMS preparation and implantation. Materials and methods: The study was conducted on 20 patients treated for Hepato-Cellular Carcinoma: 10 treated with TSR and 10 with SSR. Dose rate (DR, mSv/h) or absorbed doses (mSv) measurements were made during all steps of TSR and SSR handling: sources receipt and unpacking, preparation, transport to radiology, implantation, and patient care. Measurements were made with portable ionization chamber(Babyline/Nardeux), spectrometer(FieldSpect/Aries), digital dosimeter (NED/Unfors) and operational dosimeter (Mk2/Siemens). Values were expressed as mean±SD. Results: patients received of 1.8 GBq to 3.1 GBq of TSR and 0.55 GBq to 2.4 GBq of SSR. TSR were delivered ready-to-use with the prescribed activity. For SSR only one activity was commercially available and shipped (3 GBq at calibration-time)requiring a preparation step to adjust needed activity. DR measured during RMS was 1723 ± 157 μSv/h SSR and 1189 ± 92 μSv/h for TSR. When preparing spheres in radiopharmacy, fingers and whole body doses were respectively 8326 ± 2360 μSv and 12.3 ± 5,2 μSv for Sir-Spheres vs. 33.5 ± 7.8 μSv and 1.1 ± 0.3 μSv for TSR. DR in contact with carrying case during RMS transfer to radiology were 299 ± 102 μSv/h for SSR and 5.3 ± 1.2 μSv/h for TSR. During RMS infusion, radiologist's finger doses were limited to 3.6 ± 1 μSv for SSR and 0.7± 0.3 μSv for TSR. Finally, following RMS

McCann, Thomas E.; Kosaka, Nobuyuki; Koide, Yuichiro; Mitsunaga, Makoto; Choyke, Peter L.; Nagano, Tetsuo; Urano, Yasuteru; Kobayashi, Hisataka

Optical imaging is emerging as an important tool to visualize tumors. However, there are many potential choices among the available fluorophores. Optical imaging probes that emit in the visible range can image superficial tumors with high quantum yields, however, if deeper imaging is needed then near infrared (NIR) fluorophores are necessary. Most commercially available NIR fluorophores are cyanine based and are prone to non-specific binding and relatively limited photostability. Silica-containing rhodamine (SiR) fluorophores represent a new class of NIR fluorophores, which permit photoactivation via H-dimer formation as well as demonstrate improved photostability. This permits higher tumor-to-background ratios (TBRs) to be achieved over longer periods of time. Here, we compared an avidin conjugated with SiR700 (Av-SiR700) to similar compounds based on cyanine dyes (Av-Cy5.5 and Av-Alexa Fluor 680) in a mouse tumor model of ovarian cancer metastasis. We found that the Av-SiR700 probe demonstrated superior quenching enabling activation after binding-internalization to the target cell. As a result, Av-SiR700 had higher TBRs compared to Av-Cy5.5, and better biostability compared to Av-Alexa Fluor 680. PMID:22034863

Threshold dynamics and ergodicity of an SIRS epidemic model with Markovian switching

Science.gov (United States)

Li, Dan; Liu, Shengqiang; Cui, Jing'an

2017-12-01

This paper studies the spread dynamics of a stochastic SIRS epidemic model with nonlinear incidence and varying population size, which is formulated as a piecewise deterministic Markov process. A threshold dynamic determined by the basic reproduction number R0 is established: the disease can be eradicated almost surely if R0 disease persists almost surely if R0 > 1. The existing method for analyzing ergodic behavior of population systems has been generalized. The modified method weakens the required conditions and has no limitations for both the number of environmental regimes and the dimension of the considered system. When R0 > 1, the existence of a stationary probability measure is obtained. Furthermore, with the modified method, the global attractivity of the Ω-limit set of the system and the convergence in total variation to the stationary measure are both demonstrated under a mild extra condition.

‘Two Minds With but a Single Thought’: W. T. Stead, Henry James, and the Zancig Controversy

Directory of Open Access Journals (Sweden)

Paul Horn

2013-04-01

Full Text Available In 1906, two writers of disparate repute watched, and then wrote about a series of notorious performances by the London telepathists Julius and Agnes Zancig.One was W. T. Stead, the pugnacious purveyor of New Journalism and hugely influential in shaping public opinion; the other was Henry James, the author of a great number of highbrow, complex, and ultimately poorly selling works of prose fiction.James wrote in a letter of his impression of ‘the 'reality 'of their performance’ in the face of accusations of fraud based on a supposed ‘very wonderfully elaborated code of signalling’ between the pair.A persuasive factor was the rumour, told to him by the actor and theatre manager John Hare at a party, that Stead had proved the Zancigs’ telepathic powers during private tests at his own home.Stead published his own defence of the Zancigs in the 'Review of Reviews',' 'covering in detail their performance at the Alhambra Music Hall, and, indeed, the tests that seem likely to have been the subject of the gossip heard by James.What is especially remarkable about Stead’s article is that its description of the physical reality of telepathy is strikingly reminiscent of the instances of wordless communication that occur between the sensitive protagonists who populate James’s 'fin-de-siècle' novels.The aim of my paper is to use Stead’s and James’s shared interest in the Zancigs as a starting point from which to explore how the two writers’ authorial voices, ostensibly so different to each other, become closely imbricated as they converge on the topic of thought transference.In this way, I hope to show that in addition to the operation of rumour among their social milieu, Stead and James were connected by their appreciation of a more occulted form of communication, which would help define their apparently distinct contributions to 'fin-de-siècle' culture.

Sir Karl Popper (1902-1994): in memoriam, 15 years later.

Science.gov (United States)

Notturno, Mark Amadeus

2009-12-01

September 17th, 2009 marks the 15th anniversary of Sir Karl Popper's death. Popper was an outspoken champion of critical rationalism, and a constant critic of authoritarian tendencies in science and society. He was also one of the spiritual founders of this journal and served on its first editorial advisory board. Popper was recognized around the world as one of the 20th century's greatest philosophers of science and one of its most articulate and influential critics of Marxism and closed society. When he died, the contemporary wisdom among professional philosophers was that his philosophy was generally right-but somehow obsolete. Some commentators said that it was now obvious that scientific theories cannot be shown to be true. Others said that we had witnessed the end of history and that his critique of closed societies, while no doubt important in its day, had been fully assimilated into Western thinking and still had meaning, if at all, only for the democracies in transition that were trying to emerge from the former Soviet Union. But 15 years after his death, a look at science and society around the world gives us good reason to remember his philosophy.

Reconnaissance geologic mapping of a portion of the rain‐forest‐covered Guiana Shield, Northwestern Brazil, using SIR-B and digital aeromagnetic data

Science.gov (United States)

Pellon de Miranda, Fernando; McCafferty, Anne E.; Taranik, James V.

1994-01-01

This paper documents the result of an integrated analysis of spaceborne radar (SIR-B) and digital aeromagnetic data carried out in the heavily forested Guiana Shield. The objective of the research is to interpret the geophysical data base to its limit to produce a reconnaissance geologic map as an aid to ground work planning in a worst‐case setting. Linear geomorphic features were identified based on the interpretation of the SIR-B image. Digital manipulation of aeromagnetic data allowed the development of a color‐shaded relief map of reduced‐to‐pole magnetic anomalies, a terrace‐magnetization map, and a map showing the location of maximum values of the horizontal component of the pseudogravity gradient (magnetization boundary lines). The resultant end product was a reconnaissance geologic map where broad terrane categories were delineated and geologic faults with both topographic and magnetic expression were defined. The availability of global spaceborne radar coverage in the 1990s and the large number of existing digital aeromagnetic surveys in northwestern Brazil indicate that this approach can be potentially useful for reconnaissance geologic mapping elsewhere in the Guiana Shield.

2009-01-01

James F. T. Bugental died peacefully at age 92 at his Petaluma, California, home on September 18, 2008. Jim was a leading psychotherapist and a founding father, with Abraham Maslow and others, of humanistic psychology, or the "third force" (in contrast to psychoanalysis and behaviorism). Jim was also the creator, along with Rollo May, of existential-humanistic psychotherapy. Jim was born in Fort Wayne, Indiana, on Christmas Day in 1915. Jim earned his doctorate in 1948 from Ohio State University, where he was influenced by Victor Raimy and George Kelly. After a brief time on the University of California, Los Angeles (UCLA) faculty in psychology, Jim resigned in 1953 to found the first group practice of psychotherapy, Psychological Service Associates, with Alvin Lasko. With Abraham Maslow and others, Jim was a cofounder of the Journal of Humanistic Psychology (JHP) and the Association for Humanistic Psychology in 1961. Jim also wrote many books on the topic of psychotherapy during his lifetime.

Sir John Adams - His Legacy to the World of Particle Accelerators

CERN. Geneva

2009-01-01

John Adams acquired an unrivalled reputation for his leading part in designing and constructing the PS in CERN’s early days. In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the SPS project to approval and then to direct its construction. At the time of his untimely death in 1984 he had built Europe’s two largest proton accelerators at CERN. He went on, during the second of his terms as DG, to lay the groundwork for the proton-antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? How did he achieve political success with the Member States of CERN in turning the almost hopeless quest for approval of the SPS to CERN’s advantage? How did he view his US counterpart, R. R. Wilson? The speaker, who worked many years alongside Adams, will discuss these questions and speculate on how Sir John Adams might have viewed t...

A Historical Survey of Sir Karl Popper's Contribution to Quantum Mechanics

William M. Shields

Full Text Available Sir Karl Popper (1902-1994, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others - in this case Niels Bohr and Werner Heisenberg. Underlying Popper's criticism was his belief that, first, the Copenhagen interpretation of quantum mechanics abandoned scientific realism and second, the assertion that quantum theory was complete (an assertion rejected by Einstein among others amounted to an unfalsifiable claim. Popper insisted that the most basic predictions of quantum mechanics should continue to be tested, with an eye towards falsification rather than mere adding of decimal places to confirmatory experiments. His persistent attacks on the Copenhagen interpretation were aimed not at the uncertainty principle itself and the formalism from which it was derived, but at the acceptance by physicists of an unclear epistemology and ontology that left critical questions unanswered.

I am deeply honored to have been selected as this year's recipient of the James R. Holton Junior Scientist Award, and I receive it with heartfelt gratitude and humility. I clearly remember Peter Webster's call announcing the amazing news and how I literally remained speechless and overwhelmed. I would like to express my sincere appreciation to the Atmospheric Sciences section of AGU and the members of the award committee. I am even more appreciative to have been presented this award handed by two outstanding scientists—Peter Webster and Bill Lau—who have remarkably contributed to our understanding of the Asian monsoon and tropical climate, my area of expertise.

This research study demonstrates a numerical model intended for comprehension the spread of the year 2015 Zika virus disease utilizing the standard SIR framework. In modeling virulent disease dynamics, it is important to explore whether the illness spread could accomplish a pandemic level or it could be eradicated. Information from the year 2015 Zika virus disease event is utilized and Brazil where the event began is considered in this research study. A three dimensional nonlinear differential equation is formulated and solved numerically utilizing the Euler's method in MS excel. It is appeared from the research study that, with health intercessions of public, the viable regenerative number can be decreased making it feasible for the event to cease to exist. It is additionally indicated numerically that the pandemic can just cease to exist when there are no new infected people in the populace.

A 2-year-old girl presented to the James Paget University Hospitals Trust with croup-like symptoms and was later discharged with dexamethasone syrup. The patient re-presented 6 h later following maternal concern with signs of acute respiratory distress. After a period of clinical stability, she acutely decompensated without any prior signs of a life-threatening deterioration. She was managed using nebulised epinephrine and showed signs of clinical improvement. Although improvement persisted, the child showed signs of exhaustion following the preceding events and was later intubed with an endotracheal tube and transferred to the paediatric intensive care unit at Addenbrooke’s University Hospital, Cambridge. Endotracheal aspiration later grew parainfluenza virus, rhinovirus and Staphylococcus aureus and the patient was diagnosed with the exceptionally rare life threatening complications of croup, bacterial tracheitis. The patient was discharged from intensive care 7 days later and has since made a full recovery. PMID:22689599

Sir William Burnett (1779-1861) had an active career as a Royal Navy surgeon in the French Revolutionary and Napoleonic Wars, including service at the battles of St Vincent, the Nile and Trafalgar. From 1822 to 1855 he was professional head of the Royal Naval Medical Department, when he provided effective leadership in a time of great change. Although his official work earned him the reputation of a "hard-working, unimaginative, somewhat harsh man", his correspondence shows a very humane centre under the official carapace. His official performance and reputation were both eroded towards the end of his career by his determined promotion of zinc chloride, for which he held lucrative patents.

In this paper, we study the dynamics of a stochastic delayed SIR epidemic model with vaccination and double diseases which make the research more complex. The environment variability in this paper is characterized by white noise and Lévy noise. We establish sufficient conditions for extinction and persistence in the mean of the two epidemic diseases. It is shown that: (i) time delay and Lévy noise have important effects on the persistence and extinction of epidemic diseases; (ii) two diseases can coexist under certain conditions.

The Travels of Sir John Mandeville presents the ficticious construction of the Orient through a travels tale which is primarily shaped as a pilgrimage to Jerusalem. Over and above the critical controversy about the existence of Sir John Mandeville, this book depicts in a very accurate way several key topics in the literature of the Middle Ages as it is the conception of the travel through the medieval peregrination, the homo viator as a consequence of the religious becoming which steamed the Middle Ages, or the Bible as the geography of the known world and the destination of the medieval curiosity. On the other hand, the tale shows a very special devising of the Other, of the unknown, by means of a mythical perspective, that is, through the recreation of fascinating mirabilia collection that still impress the current reader.
