    AIM: To assess systematically the spectrum and extent of depressive symptoms comparing patient groups receiving peginterferon or conventional interferon.METHODS: Ninety-eight patients with chronic hepatitis C and interferon-based therapy (+ribavirin) were consecutively enrolled in a longitudinal study. Patients were treated with conventional interferon alfa-2b (48/98patients; 5 MIU interferon alfa-2b thrice weekly) or peginterferon alfa-2b (50/98 patients; 80-150 μgpeginterferon alfa-2b) in combination with weight-adapted ribavirin (800-1 200 mg/d). Repeated psychometric testing was performed before, three times during and once after antiviral therapy: Depression was evaluated by the Hospital Anxiety and Depression Scale (HADS), anger/hostility by the Symptom Checklist-90 Items Revised (SCL-90-R).RESULTS: Therapy with pegylated interferon alfa-2bproduces comparable scores for depression (ANOVA:P = 0.875) as compared to conventional interferon.Maximums of depression scores were even higher and cases of clinically relevant depression were frequent during therapy with peginterferon. Scores for anger/hostility were comparable for both therapy subgroups.CONCLUSION: Our findings suggest that the extent and frequency of depressive symptoms in total are not reduced by peginterferon. Monitoring and management of neuropsychiatric toxicity especially depression have to be considered as much as in antiviral therapy with unmodified interferon.

This database contains the medical records of IFN treatment collected from 36 prefectures in Japan. Multivariable logistic regression analysis was used to compare SVR rates obtained with PEG-IFN alfa-2a and alfa-2b, in combination with RBV. Results: A total of 16,349 patients were recorded in the Japanese Interferon Database. After application of the exclusion criteria, 12,706 patients (3,578 [1,710 males, 1,868 females] on PEG-IFN alfa-2a; and 9,128 [4,652 males, 4,476 females] on PEG-IFN alfa-2b were included in this analysis. The SVR rate in the PEG-IFN alfa-2b group was 62.0%, as compared with a rate of 55.1% in the PEG-IFN alfa-2a group (crude odds ratio =1.31; 95% confidence interval [CI]: 1.23 to 1.44. There was no significant difference in the adjusted SVR rates between the two groups (adjusted odds ratio =0.96; 95% CI: 0.88 to 1.05. Similar proportions of adverse events were observed in the two groups, with the exception of thrombocytopenia, retinopathy, and anemia.Conclusion: There was no significant difference in the SVR rates and safety profile

    Macroscale crystallization of zinc interferon alfa-2b was achieved on STS-52 in October 1992 in the Protein Crystallization Facility. Conditions for crystallization were established by adapting a microscale vapor diffusion method to a macroscale temperature induction method. A series of earth based pilot experiments established conditions to reproducibly crystallize zinc interferon alfa-2b in high yield and under cleanroom conditions. As a control for the STS-52 mission, a ground experiment was run simultaneously and in the same configuration as the flight experiment. Greater than 95% of the available protein crystallized in both the ground and flight experiments. Using a battery of physical, biochemical and biological characterization assays, demonstrated that sample processing, polysulfone bottle confinement and the conditions used for crystallization did not have a negative effect on protein integrity. Redissolved crystals from the flight and ground experiments showed full biological activity in a cytopathic effect inhibition assay as compared to an interferon control standard. Morphometric analysis comparing the overall length and width of the derived crystals showed a 2.4 fold increase in the length and width of the space grown crystals as compared to earth grown crystals. Space grown crystals have remained a stable free flowing suspension for over 2 years. Based on these results, further experiments are envisioned to investigate macroscale crystallization of biologically active macromolecules in microgravity.

The traditional treatment for CIN is surgical excision usually with adjunctive cryotherapy. However, residual tumour may remain, which can lead to recurrence rates of more than 50%. 5-Fluorouracil, mitomicyn C and interferon alfa 2b are new pharmacological agents that have proved their efficacy in the treatment of CIN. As side effects are common, we present IFN alfa 2b as a single therapeutic agent as an effective and optimal treatment for presumed recurrent corneal and conjunctival intraepithelial neoplasia. It offers the benefits of topical therapy and avoids the risks of surgical or other interventions - specifically, ocular surface toxicity, cicatricial conjunctival changes, and limbal stem cell deficiency.

    AIM: To study the safety and efficacy of pegylated interferon alfa-2b, indigenously developed in India, plus ribavirin in treatment of hepatitis C virus(HCV). METHODS: One-hundred HCV patients were enrolled in an open-label, multicenter trial. Patients were treated with pegylated interferon alfa-2b 1.5 μg/kg per week subcutaneously plus oral ribavirin 800 mg/d for patients with genotypes 2 and 3 for 24 wk. The same dose of peginterferon plus weight-based ribavirin(800 mg/d for ≤ 65 kg; 1000 mg/d for > 65-85 kg; 1200 mg/d for > 85-105 kg; 1400 mg/d for > 105 kg body weight) was administered for 48 wk for patients with genotypes 1 and 4. Serological and biochemical responses of patients were assessed.RESULTS: Eighty-two patients(35 in genotypes 1 and 4 and 47 in 2 and 3), completed the study. In genotype 1, 25.9% of patients achieved rapid virologic response(RVR): while the figures were 74.1% for early virologic response(EVR) and 44.4% for sustained virologic response(SVR). For genotypes 2 and 3, all patients bar one belonged to genotype 3, and of those, 71.4%, 87.5%, and 64.3% achieved RVR, EVR, and SVR, respectively. In genotype 4, 58.8%, 88.2%, and 52.9% of patients achieved RVR, EVR, and SVR, respectively. The majority of patients attained normal levels of alanine aminotransferase by 4-12 wk of therapy. Most patients showed a good tolerance for the treatment, although mild-to-moderate adverse events were exhibited; only two patients discontinued the study medication due to serious adverse events(SAEs). Eleven SAEs were observed in nine patients; however, only four SAEs were related to study medication.CONCLUSION: Peginterferon alfa-2b, which was developed in India, in combination with ribavirin, is a safe and effective drug in the treatment of HCV.

    Full Text Available Background: Pegylated interferon and ribavirin are currently one of the accepted treatment for chronic Hepatitis C. Dermatologic complications of interferon have been reported, but to date a few cases of bacterial cellulitis; a rare and severe complication, have been published. Cellulitis is a common infectious process affecting the skin and subcutaneous tissues which results in significant morbidity and holds considerable healthcare costs.Cases Report: Herein, we report a case of chronic hepatitis C genotype 1a who was on medication since 8 weeks prior to developing leg cellulitis, an uncommon pegylated interferon injection site. Considering no other possible risk factors were found to be in favor of bacterial cellulitis, our case is unique in its kind. Some reports reveal necrotizing vasculitis as basis for cutaneous lesions, which could be due to the high concentrations of drug at the injection site, a toxic effect of the diluents, or an immunological reaction.Conclusion: According to the latter mechanism patients could develop bacterial cellulitis in their different organs. Conclusively, we propose the hypothesis of a possible association between cellulitis to occur at any site as the complication of pegylated interferon Alfa 2b and would highlight the role of a careful skin examination that could be an asset in preventing local skin infections.

    Autoimmune manifestations are common both in patients chronically infected by hepatitis C virus, and in patients transplanted for non-autoimmune diseases. A correlation between interferon based treatment and autoimmune diseases or the development of autoantibodies is well established in non-transplanted patients, but few data are available about transplanted patients. It is unclear whether interferon may increase the incidence of acute cellular rejection and there are few reports on the development of atypical autoimmune manifestations during post-liver transplantation interferon or pegylated interferon treatment. We describe a case of systemic lupus erythematosus following treatment with pegylated interferon alfa-2b in a transplanted patient with recurrence of chronic hepatitis C. Our experience suggest that pegylated interferon may induce autoimmune diseases in the immunosuppressed host, different from acute cellular rejection and call for a great attention to possible autoimmune disorders development during interferon based treatments in liver transplanted patients.

    Full Text Available Aimis to determine the efficacy of Allergoferon® — combined medicine composed of interferon alfa-2b and loratadine gel for topical and external use — in ocular allergies treatment.Materials and methods. 60 patients with allergic eye diseases were treated. Allergoferon® gel applied QID on upper and lower eyelids was used as a first-line therapy. Efficacy was measured using the following criteria: chemozis, eyelid edema, conjunctival redness and discharge, the presence of conjunctival follicles and papillae. All symptoms were scored using a 4‑point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe.Results. Topical administration of Allergoferon® was associated with significant symptoms reduction, i.e., chemozis by 82 %, eyelid edema by 91 %, conjunctival redness by 79 %, eyelid redness by 88 %, conjunctival discharge by 95 %, the presence of conjunctival follicles and papillae by 76 %.Conclusion. Allergoferon® gel for topical and external use quickly reduces tissue allergic reactions and, consequently, terms of treatment. This medication is highly-effective as a therapy of ocular allergies owing to its antihistamine, anti-inflammatory and anti-exudative effects.

    Full Text Available Purpose: To report a case of primary acquired melanosis (PAM successfully treated with combined topical mitomycin C and interferon-α2b. Case Report: A 75-year-old man presented with an extensive unilateral pigmented lesion involving 360° of the bulbar conjunctiva, extending to the fornices and palpebral conjunctiva. Map biopsy confirmed PAM with local atypia. Treatment was initiated with mitomycin C 0.04% eye drops for two courses. Although the lesion markedly responded to the treatment, residual lesions justified further therapy. To avoid ocular surface toxicity induced by excessive mitomycin C exposure, interferon-α2b eye drops were started and continued for 6 months. The pigmented lesion almost completely disappeared and no significant complication or recurrence was observed for 24 months. Conclusion: Combination therapy using mitomycin C and interferon-α2b for PAM with atypia may be recommended as an effective treatment modality, avoiding the ocular surface toxicity due to excessive mitomycin C exposure.

    Two children who acquired hepatitis C virus (HCV) and human immunodeficiency virus type 1 (HIV-1) infection by mother-to-child transmission were monitored during interferon alfa-2b and ribavirin treatment. In Patient C1, CD4(+) T cell counts were within normal range and HIV-1 viral load was undetectable. HCV viral load declined slightly following treatment initiation while novel variants rapidly emerged, indicative of quasispecies diversification. In Patient C2, CD4(+) T cell counts were low and HIV-1 replication was not fully controlled by antiretroviral therapy. HCV viral load rose during treatment and a striking conservation of the variant spectrum was observed. In both cases, there was no decline in quasispecies complexity following treatment initiation and sustained virological response was not achieved. These results suggest that reduction in quasispecies complexity, which is observed in adult responders following interferon treatment, may be mechanistically unrelated with evolution of the variant profile and/or selective pressure exerted on HCV.

Health care resource utilization and costs of services (converted to 2009 dollars were evaluated. Cost refers to the amount paid to providers associated with the health service.Results: Of 18,075 subjects with melanoma surgery claims, 1525 (8.4% were treated with IFN and 1194 (6.6% with other chemotherapies. Median duration (days and number of doses of IFN therapy were 29 and 20, respectively. Approximately half of patients who received IFN discontinued therapy within or after the one-month induction phase. For IFN therapy patients, average total cost per patient for the last melanoma-related surgery prior to start of therapy, including costs of the surgery itself, pathology, anesthesia, and hospital care, was $2219. The average total cost per patient related to IFN therapy was $1188; this included costs for drug, office visits, blood work, and infusions.

  6. Tolerability of intensified intravenous interferon alfa-2b versus the ECOG 1684 schedule as adjuvant therapy for stage III melanoma: a randomized phase III Italian Melanoma Inter-group trial (IMI – Mel.A.) [ISRCTN75125874

    International Nuclear Information System (INIS)

    High-dose interferon alfa-2b (IFNalfa-2b), according to the ECOG 1684 schedule, is the only approved adjuvant treatment for stage III melanoma patients by the FDA and EMEA. However, the risk/benefit profile has been questioned limiting its world-wide use. In the late nineties, the Italian Melanoma Inter-group started a spontaneous randomized clinical trial (RCT) to verify if a more intense, but shorter than the ECOG 1684 regimen, could improve survival without increasing the toxicity profile. The safety analysis in the first 169 patients who completed the treatment is here described. Stage III melanoma patients were randomized to receive IFNalfa-2b 20 MU/m2/d intravenously (IV) 5 days/week × 4 weeks, repeated for three times on weeks 9 to 12, 17 to 20, 25 to 28 (Dose-Dense/Dose-Intense, DD/DI, arm), or IFNalfa-2b 20 MU/m2/d IV 5 days/week × 4 weeks followed by 10 MU/m2 subcutaneously (SC) three times per week × 48 weeks (High Dose Interferon, HDI, arm). Toxicity was recorded and graded, according to the WHO criteria, as the worst grade that occurred during each cycle. The most common toxicities in both arms were flu-like and gastrointestinal symptoms, leukopenia, liver and neuro-psichiatric morbidities; with regard to severe toxicity, only leukopenia was statistically more frequent in DD/DI arm than in HDI arm (24% vs 9%) (p = 0.0074), yet, this did not cause an increase in the infection risk. Discontinuation of treatment, due to toxicity, was observed in 13 and 17% of the patients in the DD/DI and HDI arm, respectively. The median actual dose intensity delivered in the DD/DI arm (36.4 MU/m2/week) was statistically higher than that delivered in the HDI arm (30.7 MU/m2/week) (p = 0.003). Four cycles of intravenous high-dose IFNalfa-2b can be safely delivered with an increase in the median dose intensity. Efficacy results from this trial are eagerly awaited

Aims: thalidomide posses anti-inflammatory and immunomodulatory properties through inhibition of tumor necrosis factor and costimulatory effect on human CD8+ T cells. Methods: we started a prospective, open label trial of retreatment of very-difficult-to-treat genotype 1 chronic hepatitis C patients (CHC patients, who had failed to respond to the (Peg-IFN/RBV, with a triple therapy consisting in these same antivirals plus thalidomide 200 mg/day (the TRITAL study. Results: none of the eleven patients fulfilling the inclusion criteria and included in the trial reached complete early virological response or sustained virological response. Viral load decline after 12 weeks of triple therapy thalidomide-based retreatment did not differ from viral dynamics during the first course. The triple therapy was well tolerated and only one patient developed mild bilateral neuropathy. Conclusions: thalidomide addition to standard therapy is tolerated and did not increase the SVR rate in very-difficult-to-treat genotype 1 CHC patients. Different schedules are warranted to improve attempting retreatment of non responder CHC patients.Antecedentes: menos de la mitad de los pacientes con hepatitis C logra eliminar el virus de manera sostenida después de la terapia con peginterferón alfa y ribavirina (Peg-IFN/RBV.

Objectives: to evaluate response to treatment in patients who were non-responders to previous treatment. Methods: one hundred and twenty-four patients who were non-responders to previous treatment were included. All patients were treated with PEG alpha 2b interferon (dose: 1.5 mg/kg body weight and RBV (weight-dependent dosage. A qualitative PCR of virus C after six months was evaluated. In those in whom this was positive, treatment was discontinued; in those who were negative treatment was continued to the end of the year. Results: response following treatment (RFT was 35.4% (44 patients, and sustained viral response (SVR 29.8% (37 patients. No relation was observed between RFT, SVR and any previous treatment. RFT was dependent on low initial viremia and SVR was significantly and independently related to low serum hepatitis C RNA and a non-1 genotype. In general, treatment was well tolerated. Medication was discontinued in 5 patients, and doses reduced in 18. Conclusion: on retreatment with PEG and RBV a SVR of 29.8% was achieved in patients who had not responded to previous treatment, so its use in this group of patients is indicated.Introducción: existe poca información del resultado del tratamiento con interferón pegilado (PEG y ribavirina (RBV en enfermos con hepatitis crónica por virus C (HCC no respondedores a tratamientos previos.

    Full Text Available Alfa, also known as Stipa tenacissimaI or “halfa”, is grown in North Africa and south Spain. Due to its short fiber length, paper made from alfa pulp retains bulk and takes block letters well. In this study alfa was evaluated for bleached pulp production. Two cellulose pulps with different chemical compositions were pulped by a conventional kraft process. One sample was taken from the original alfa material and another from alfa that had been pretreated by diluted acid. The pulp produced from the pretreated alfa was bleached by the elemental-chlorine-free sequences DEPD and DEDP. The yield, Kappa number, brightness, and α- cellulose content of bleached and unbleached pulps were evaluated. The results showed that during the chemical pulping process, treated alfa cooked more easily than the original alfa. The treated alfa pulp also showed very good bleaching, reaching a brightness level of 94.8% ISO with a yield of 93.6% at an α-cellulose content 96.8(% with a DEDP bleaching sequence, compared to 83.2% ISO brightness level, 92.8% yield, and 95.1% α-cellulose content for bleached pulp with a DEPD bleaching sequence. Therefore, this alfa material could be considered as a worthwhile choice for cellulosic fiber supply.

O modelo de Markov desenvolvido projetou a evolução da hepatite C em coorte de 1.000 pacientes, por um período de 30 anos, para os vários estados do desenvolvimento da doença. As terapias combinadas da ribavirina com o alfapeguinterferon 2a ou 2b apresentam efetividades estatisticamente idênticas quando avaliadas em 30 anos de evolução da doença. Quanto ao impacto do tratamento nos anos de vida e nos anos de vida ajustados por qualidade de vida; os anos de vida ganhos por qualidade de vida em relação à evolução da doença sem tratamento foram de 1,67 e 1,63, respectivamente, para a terapia combinada com alfapeguinterferon 2a e 2b, aplicando-se 5% de desconto. A estratégia de tratamento com alfapeguinterferon 2a mais ribavirina se revelou mais custo-efetiva, dominando a outra alternativa de tratamento. Embora não haja diferenças significativas de efetividade entre os dois tipos de alfapeguinterferon, a diferença de preço entre os dois medicamentos faz com que a alternativa do uso do alfapeguinterferon 2a mais ribavirina seja mais eficiente. Quanto à estimativa do impacto orçamentário para o período de 2008 a 2017, a utilização do alfapeguinterferon 2a mais ribavirina resulta em redução nos gastos de aproximadamente 19%, caso todos os doentes fossem tratados utilizando-se os esquemas terapêuticos selecionados.A cost-effectiveness and budget impact of treatments given to adults infected with genotype 1 hepatitis C virus was performed by comparing the non-treatment with combined therapy alfapeguinterferon-2a and 2b and ribavirin.

    2015-12-01

    ALFA fits emission line spectra of arbitrary wavelength coverage and resolution, fully automatically. It uses a catalog of lines which may be present to construct synthetic spectra, the parameters of which are then optimized by means of a genetic algorithm. Uncertainties are estimated using the noise structure of the residuals. An emission line spectrum containing several hundred lines can be fitted in a few seconds using a single processor of a typical contemporary desktop or laptop PC. Data cubes in FITS format can be analysed using multiple processors, and an analysis of tens of thousands of deep spectra obtained with instruments such as MUSE will take a few hours.

    The current European Pharmacopoeia (Ph. Eur.) texts for Interferon (IFN)-alfa-2 include a nonspecific photometric protein assay using albumin as calibrator and a highly variable cell-based assay for the potency determination of the protective effects. A request was expressed by the Official Medicines Control Laboratories (OMCLs) for improved methods for the batch control of recombinant interferon alfa-2 bulk and market surveillance testing of finished products, including those formulated with Human Serum Albumin (HSA). A HPLC method was developed at the Medical Products Agency (MPA, Sweden) for the testing of IFN-alfa-2 products. An initial collaborative study run under the Biological Standardisation Programme (BSP; study code BSP039) revealed the need for minor changes to improve linearity of the calibration curves, assay reproducibility and robustness. The goal of the collaborative study, coded BSP071, was to transfer and further validate this improved HPLC method. Ten laboratories participated in the study. Four marketed IFN-alfa-2 preparations (one containing HSA) together with the Ph. Eur. Chemical Reference Substance (CRS) for IFN-alfa-2a and IFN-alfa-2b, and in-house reference standards from two manufacturers were used for the quantitative assay. The modified method was successfully transferred to all laboratories despite local variation in equipment. The resolution between the main and the oxidised forms of IFN-alfa-2 was improved compared to the results from the BSP039 study. The improved method even allowed partial resolution of an extra peak after the principal peak. Symmetry of the main IFN peak was acceptable for all samples in all laboratories. Calibration curves established with the Ph. Eur. IFN-alfa-2a and IFN-alfa-2b CRSs showed excellent linearity with intercepts close to the origin and coefficients of determination greater than 0.9995. Assay repeatability, intermediate precision and reproducibility varied with the tested sample within acceptable

Así se va depauperando la expresión “derechos humanos”, que actualmente tiende a confundirse con unas instancias en las que pueden frustrarse frecuentemente las esperanzas de quien busca justicia. Para que una declaración sea completa es necesario fundamentarla en la constitución universal humana. Solamente así quedará asegurada y garantizada su inviolabilidad. En efecto, la primera violación a los derechos humanos consiste en descuidar el deber urgente de aclarar la respuesta a la pregunta “¿qué es el ser humano?” De hecho, el tema de los derechos humanos debe ser fundamentalmente ontológico-antropológico. De la postura antropológica derivará el tema axiológico de la dignidad del ser humano. De la postura axiológica brotará el tema deontológico del deber ser del ser humano.

    2016-01-01

    The operation experience with ATLAS ALFA detectors in the LHC environment during the Run1 period has shown significant beam-induced heating. Subsequent comprehensive studies revealed that heating effects could be disastrous in the case of the larger beam intensities foreseen for higher luminosities in the LHC Run2. During the first LHC long shutdown (LS1) all ALFA detectors have been removed from the LHC tunnel and their covers - Roman Pots - underwent a geometry upgrade to minimize the impedance losses. It will be shown that this modification together with a system improving the internal heat transfer and an air cooling system, significantly shifted the temperatures of ALFA detectors away from the critical limits throughout the LHC Run2. Also ALFA trigger system was considerably upgraded to keep measured data safely inside the Run2 ATLAS latency budget and to minimize dead time. The needed hardware changes of the trigger system will be presented in the second part of the talk.

Recombinant human follicle-stimulating hormone (r-hFSH; follitropin alfa and recombinant human luteinizing hormone (r-hLH; lutropin alfa can be administered individually or in a fixed combination. The ability to vary the FSH to LH dose ratio in a single injection without compromising the bioactivity of either gonadotrophin or generating losses of active principle is important for physicians and patients alike. Methods This study investigated whether follitropin alfa (GONAL-f (R, as lyophilized powder for reconstitution or solution from the GONAL-f (R (filled-by-mass [FbM] Prefilled Pen, could be used to reconstitute Pergoveris TM (follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder. In Ratio Groups 1 and 2, the r-hFSH:r-hLH ratio was 3:1; in Ratio Groups 3 and 4, the ratios of r-hFSH:r-hLH were 5:1 and 8:1, respectively. The protein content and bioactivity of each mixed solution were evaluated. The r-hFSH and r-hLH content was determined using reverse-phase high performance liquid chromatography. The biological activity of r-hFSH and r-hLH was assessed using the Steelman-Pohley and Van Hell in vivo bioassays in rats, respectively. Results Follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder could be successfully mixed with follitropin alfa 75 IU FbM solution that was either reconstituted from lyophilized powder or injected directly from the prefilled pen to create solutions with ratios of r-hFSH and r-hLH from 3:1 to 8:1. The measured content of r-hFSH and r-hLH corresponded favourably with the target protein content in Ratio Groups 1–4. The in vivo target and measured bioactivity of r-hFSH and r-hLH were also closely matched in all Ratio Groups. Conclusion Follitropin alfa lyophilized powder or solution can be accurately mixed with follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder to

In contrast to traditional emission line fitting methods which require the identification of spectral features suspected to be emission lines, ALFA instead uses a list of lines which are expected to be present to construct a synthetic spectrum. The parameters used to construct the synthetic spectrum are optimised by means of a genetic algorithm. Uncertainties are estimated using the noise structure of the residuals. An emission line spectrum containing several hundred lines can be fitted in a few seconds using a single processor of a typical contemporary desktop or laptop PC.

Where discrepancies exist, the manually measured fluxes are found to be less accurate than those returned by ALFA. Together with the code NEAT (Wesson et al. 2012), ...

  1. Interferon alfa and ribavirin induced hair changes

    International Nuclear Information System (INIS)

    Combination therapy of Interferon alfa and ribavirin in chronic hepatitis C has well documented cutaneous adverse effects. Most interesting of these has been reported on hair physiology. This study was conducted to determine the frequency and pattern of adverse effects involving hair in patients receiving combination of interferon alfa 2a and ribavirin for chronic hepatitis C. The study was conducted in Department of Dermatology, Division of Medicine Shaikh Zayed Hospital. Thirty Eight patients who completed treatment with interferon alfa (3 MIU subcutaneously thrice weekly) and 1200 mg ribavirin daily for 24 weeks were enrolled in this single-center study. The patient's response and examination finding particularly regarding involvement of hair was noted on a Proforma. Thirty Two out of thirty eight (84%) patients noted adverse effects involving hair. The most frequent was diffuse hair loss and occurred in 27 patients (71%). Hypertrichosis of eyelashes (trichomegaly) and eyebrows (synophyrs) was observed in 18 (47%) and 16 (42%) patients respectively. Graying of hair was noted in 4 patients (11%), while discoloration of moustache hair was seen in 2 patients (5%). Epilation at the site of subcutaneous injection was noted in 10 patients (26%). Alopecia areata was reported in 2 patients (5%). It is concluded that adverse effects involving hair are frequent and varied (hair loss to excess hair growth) during combination therapy with Interferon alfa-2a and Ribavirin for chronic hepatitis C.

    2016-01-01

    Background. Hypophosphatasia (HPP) is caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Consequently, cell-surface deficiency of TNSALP phosphohydrolase activity leads to extracellular accumulation of inorganic pyrophosphate, a natural substrate of TNSALP and inhibitor of mineralization. Children with HPP can manifest rickets, skeletal pain, deformity, fracture, muscle weakness, and premature deciduous tooth loss. Asfotase alfa is a recombinant, bone-targeted, human TNSALP injected s.c. to treat HPP. In 2012, we detailed the 1-year efficacy of asfotase alfa therapy for the life-threatening perinatal and infantile forms of HPP. Methods. Here, we evaluated the efficacy and safety of asfotase alfa treatment administered to children 6–12 years of age at baseline who were substantially impaired by HPP. Two radiographic scales quantitated HPP skeletal disease, including comparisons to serial radiographs from similarly affected historical control patients. Results. Twelve children receiving treatment were studied for 5 years. The 6-month primary endpoint was met, showing significant radiographic improvement. Additional significant improvements included patient growth, strength, motor function, agility, and quality of life, which for most patients meant achieving normal values for age- and sex-matched peers that were sustained at 5 years of treatment. For most, pain and disability resolved. Mild to moderate injection-site reactions were common and were sometimes associated with lipohypertrophy. Low anti–asfotase alfa antibody titers were noted in all patients. No evidence emerged for clinically important ectopic calcification or treatment resistance. Conclusions. Asfotase alfa enzyme replacement therapy has substantial and sustained efficacy with a good safety profile for children suffering from HPP. Trial Registration.

    Cordes, J. M.

    2008-02-01

    A large scale survey for pulsars and transients is being conducted at the Arecibo Observatory using the Arecibo L-band Feed Array (ALFA). Data acquisition so far has been with correlation spectrometers that analyze a 0.1 GHz bandwidth at 1.4 GHz. The 256 frequency channels limit dispersion smearing to 1.2 ms at DMmax = 103 pc cm-3 while the sampling interval of 64 μs equals the dispersion smearing at DM~54 pc cm-3, providing high sensitivity to millisecond pulsars with standard periods out to implied distances of several kpc at low Galactic latitudes. In early 2008, we will use a new set of polyphase filter bank systems that provide the same time and frequency resolutions but over ALFA's full 0.3 GHz bandwidth. Currently the survey covers sky positions within 5° of the Galactic plane that are reachable with Arecibo. Preliminary results are given for some of the discoveries made so far, which include millisecond pulsars, a relativistic binary pulsar, a likely counterpart of a Compton GRO/EGRET gamma-ray source, and transient pulsars (including `RRATs''). We discuss the methodology of the survey, which includes archival of raw survey data at the Cornell Center for Advanced Computing and processing at distributed sites. The survey and follow up observations, which include timing observations, multiwavelength searches for orbital companions in the case of binary pulsars, etc. are organized through the Pulsar-ALFA (PALFA) Consortium. We expect the Galactic plane survey to continue until at least 2010, most likely involving multiple passes on each sky position to optimize detection of variable sources. The ALFA system will also be used to survey intermediate Galactic latitudes for millisecond pulsars, relativistic binaries with large systemic velocities, and runaway pulsars that will escape the Galaxy.

Se abordó la investigación enmarcada en una metodología de tipo positivista con técnicas estadísticas. Se concluyó que los recursos escasos y las dificultades históricas exigen un incremento de esfuerzos presupuestarios y de gestión, en cantidad, calidad y transparencia por parte del Estado a través del gasto público. En los últimos años, el Estado no ha aprovechado plenamente el potencial de la política fiscal y los periodos de bonanza económica, precedidos por los auspiciosos auges petroleros, para fomentar, estimular y consolidar el desarrollo humano que permita a la población en general tener calidad de vida cónsonos con una sociedad conducente al bienestar general sostenible y permanente. Esto se explica por diversas limitaciones y retos afrontados, como la falta de diversificación del financiamiento y gasto público, la exigua carga fiscal, la corrupción dentro de la praxis política, la estructura mayormente regresiva del sistema de recaudación, el gasto público y social insuficiente e inequitativo.

    The Arecibo L-Band Feed Array Zone of Avoidance (ALFA ZOA) Deep Survey is the deepest and most sensitive blind Hi survey undertaken in the ZOA. ALFA ZOA Deep will cover about 300 square degrees of sky behind the Galactic plane in both the inner (30 deg < l < 75 deg; b < |2 deg|) and outer (175 deg < l < 207 deg; -2 deg < b < +1 deg) Galaxy, using the Arecibo Radio Telescope. First results from the survey have found 61 galaxies within a 15 square degree area centered on l = 192 deg and b = -2 deg. The survey reached its expected sensitivity of rms = 1 mJy at 9 km/s channel resolution, and is shown to be complete above integrated flux, F_HI = 0.5 Jy km/s. The positional accuracy of the survey is 28 arcsec and detections are found out to a recessional velocity of nearly 19,000 km/s. The survey confirms the extent of the Orion and Abell 539 clusters behind the plane of the Milky Way and discovers expansive voids, at 10,000 km/s and 18,000 km/s. 26 detections (43%) have a counterpart in the li...

    Full Text Available Introduction. Hepatitis C virus (HCV infection is one of the main causes of chronic liver disease worldwide. Pegylated interferon alfa-2a or 2b (PEG IFN alfa-2a or 2b and ribavirin (RBV represent a standard treatment of chronic hepatitis C (CHC. Sustained virological response (SVR, defined as continued undetectable HCV RNA 24 weeks after completion of treatment, is universally considered as an indicator of treatment efficacy. Objective. The aim of this study was to determine efficacy and safety of PEG IFN alfa-2a and RBV treatment in patients with CHC in Serbia. Methods. One hundred seventy-six patients with CHC were included in this multicenter trial from 8 reference centers in Serbia. The patients were treated with standard PEG IFN alfa- 2a and RBV protocol. We performed the following virological testing: anti-HCV (ELISA, HCV RNK (quantitative PCR, HCV genotype (type-specific PCR, HBsAg, anti-HBs, anti-HBc and anti-HIV (ELISA. Histological activity and the degree of fibrosis were determined according to the Metavir scoring system. Potential predictors for achieving SVR were evaluated using multivariable logistic regression analysis. Results. Of the treated patients with CHC 65.9% were male, and 60.2% of them aged over 40 years. Of the treated patients 68.2% had infection over 5 years, 63% had HCV RNA >400.000 IU/mL, 76.1% had HCV G1/4, and 60.1% had a mild to moderate liver fibrosis. SVR was achieved in 78.9% of patients (G1/4 79.1%; G2/3 78.1%. The factors that indicated a poorer efficacy of the treatment were age >40 (p<0.05, high basal viremia (p=0.013, and the reduction of PEG IFN alfa-2a and RBV doses, with interruption of therapy (p<0.001. Of the treated patients 45.9% had adverse affects (G1/4 50.8%; G2/3 29.7%. Conclusion. Treatment of CHC with PEG IFN alfa-2a and RBV was efficient in 78.9% of patients. The safety profile of therapy was satisfactory. Longer therapy increases the possibility of the development of adverse affects. No

Así, tanto la Declaración Universal de los Derechos Humanos como otros instrumentos internacionales aprobados por las Naciones Unidas son normas jurídicas globalizadoras, surgidas con la idea de extender la vigencia de los derechos básicos de la persona a todos los países del mundo. Desde esta otra visión de la globalización, conseguir la efectiva vigencia de los derechos humanos en los países de Centroamérica resulta una tarea particularmente urgente y necesaria. En efecto, salvo Costa Rica, que puede considerarse una afortunada excepción en la turbulenta historia política centroamericana, todos los demás Estados de la región comparten un pasado marcado por los graves conflictos internos y el escaso desarrollo económico, circunstancias ambas que explican en buena parte un presente caracterizado por la debilidad de las instituciones, la falta de cohesión social y, en consecuencia, la insuficiente garantía de los derechos más básicos de la mayoría de la población.

    The recently started Arecibo L-band Feed Array (ALFA) pulsar survey aims to find ~1000 new pulsars. Due to its high time and frequency resolution the survey is especially sensitive to millisecond pulsars, which have the potential to test gravitational theories, detect gravitational waves and probe the neutron-star equation of state. Here we report the results of our preliminary analysis: in the first months we have discovered 21 new pulsars. One of these, PSR J1906+0746, is a young 144-ms pulsar in a highly relativistic 3.98-hr low-eccentricity orbit. The 2.61 +- 0.02 solar-mass system is expected to coalesce in ~300 Myr and contributes significantly to the computed cosmic inspiral rate of compact binary systems.

    Full Text Available Debra S Regier, Pranoot Tanpaiboon Division of Genetics and Metabolism, Children’s National Medical Center, Washington, DC, USA Abstract: Mucopolysaccharidosis type IVA (MPS IVA or Morquio A is an autosomal recessive lysosomal storage disease which results in a striking skeletal phenotype, but does not negatively impact the intellect of the patient. MPS IVA has a phenotypic continuum that ranges from a severe and rapidly progressing form to a slowly progressive form. The clinical diagnosis is often made in the preschool years based on abnormal bone findings on physical examination and dysplasia on radiographic imaging. Supportive care has been the mainstay in caring for patients. Orthopedic physicians often form the core of the care team due to the early and severe skeletal abnormalities; however, systemic disease is common and requires aggressive monitoring and management. Interdisciplinary care teams often consist of medical geneticists, cardiologists, pulmonary specialists, gastroenterologists, otolaryngologists, audiologists, and ophthalmologists. With the US Food and Drug Administration’s approval of elosulfase alfa, patients >5 years of age now have access to this medication from the time of diagnosis. The clinical trial with once weekly intravenous dosing (2.0 mg/kg per week showed improvement in the 6-minute walk test. The composite end point analysis to evaluate the combining changes from baseline in 6-minute walk test, 3-minute stair climb test, and respiratory function showed that at a dose of 2.0 mg/kg per week, subjects performed better when compared to placebo. This indication was clinically meaningful in the treatment group. The treatment was generally well tolerated, and the uncommon infusion reactions responded well to traditional enzyme replacement therapy infusion reaction management algorithms. Currently, clinical trials are underway to determine the efficacy and safety in MPS IVA patients <5 years of age. Keywords

El progreso científico conseguido se ha fraguado en cuatro fases que se corresponden, aproximadamente, con los cuatro cuartos del siglo XX. El primero estableció las bases celulares de la herencia: los cromosomas. El segundo definió las bases moleculares de la herencia: la doble hélice de ADN. El tercero descifró las bases informativas de la herencia con el descubrimiento de los mecanismos biológicos mediante los que la célula lee la información codificada en los genes; luego, con la invención de la tecnología del ADN recombinante de clonajey de secuenciación, los científicos pudieron hacer lo mismo. El último cuarto del siglo estuvo marcado por un lento pero constante esfuerzo para descifrar genes primero y, por fin, genomas enteros que han propiciado el desarrollo de la genómica.

    Darbepoetin alfa is a biopharmaceutical glycoprotein that stimulates erythropoiesis and is used to treat anemia, which associated with renal failure and cancer chemotherapy. We herein describe the structural characterization of recombinant darbepoetin alfa produced by Leishmania tarentolae T7-TR host. The DNA expression cassette was integrated into the L. tarentolae genome through homologous recombination. Transformed clones were selected by antibiotic resistance, diagnostic PCRs, and protein expression analysis. The structure of recombinant darbepoetin alfa was analyzed by isoelectric focusing, ultraviolet-visible spectrum, and circular dichroism (CD) spectroscopy. Expression analysis showed the presence of a protein band at 40 kDa, and its expression level was 51.2 mg/ml of culture medium. Darbepoetin alfa have 5 isoforms with varying degree of sialylation. The UV absorption and CD spectra were analogous to original drug (Aranesp), which confirmed that the produced protein was darbepoetin alfa. Potency test results revealed that the purified protein was biologically active. In brief, the structural and biological characteristics of expressed darbepoetin alfa were very similar to Aranesp which has been normally expressed in CHO. Our data also suggest that produced protein has potential to be developed for clinical use. PMID:27282622

    Merkel cell carcinoma (mcc) is a highly aggressive neuroendocrine tumour of the skin. Remission rates are high with chemotherapy in patients with metastasis, but without any improvement in overall survival. We present the case of a 90-year-old woman with facial mcc. After radiation and surgery, the mcc recurred with widespread cutaneous and regional lymph node metastases. The metastases were treated with weekly intralesional injections of 1-2×10(6) IU interferon alfa-2a, accompanied by topical imiquimod 5% cream 3 times weekly. After partial regression, subcutaneous pegylated interferon alfa-2b was added at a dose of 30 μg weekly, which was then increased to 50 μg weekly. At 4 months after the start of immunotherapy, all cutaneous metastases and the intralesionally treated lymph node metastases receded. Interruption or reduction of systemic interferon application resulted in locoregional relapses that were successfully treated with surgery or intralesional interferon injections. The patient remains alive 30 months after initiation of immunotherapy, suggesting that locally metastasized mcc might be able to be controlled with local and systemic immunotherapy. PMID:27122984

    Full Text Available Abstract In order to examine whether variation in interleukin-10 promoter polymorphism would predict the likelihood of sustain response of chronic hepatitis B to treatment with interferon alfa (IFN-α, the inheritance of 3 biallelic polymorphisms in the IL-10 gene promoter in patients with 52 chronic hepatitis B were determined by polymerase chain reaction (PCR-bared techniques, restriction enzyme digestion or direct sequencing. The relationship to the outcome of antiviral therapy for chronic HBV infection was studied in 24 patients who had a virologically sustained response(SR and in 28 non-responder(NR to interferon alfa-2b and several IL-10 variants were more frequent among SR compared with NR. Carriage of the -592A allele, -592A/A genotype and -1082/-1819/-592 ATA haplotype was associated with SR. Our findings indicate that heterogeneity in the promoter region of the IL-10 gene has a role in determining the initial response of chronic hepatitis B to IFN-α therapy.

    Full Text Available Abstract Background Anemia is common among peritoneal dialysis (PD patients, and most patients require erythropoiesis-stimulating agents (ESA to maintain their hemoglobin concentrations within current guideline recommendations. Darbepoetin alfa is an ESA with a 3-fold longer half-life and greater in vivo biological activity than recombinant human erythropoietin, allowing less frequent dosing that may simplify anemia management in these patients, providing benefits to patients, care givers and health care providers. Clinical studies have confirmed the efficacy and safety of darbepoetin alfa administered at extended dosing intervals. However, there are limited data on the management of anemia with ESAs in PD patients in routine clinical practice. The aim of this multicenter observational study in European and Australian dialysis patients was to evaluate darbepoetin alfa administered once every 2 weeks (Q2W in routine clinical practice for 12 months. Methods PD patients ≥18 years old and converting to treatment with darbepoetin alfa Q2W were eligible for enrollment regardless of previous or current ESA use. Patients enrolled in the study were treated according to local usual clinical practice. Data were collected up to 6 months prior to and 12 months after conversion to darbepoetin alfa Q2W. The primary endpoint was hemoglobin concentration 12 months after conversion to darbepoetin alfa Q2W. Results Of the 741 eligible PD patients (mean age, 61 years; male, 57%, 640 (86% completed the study.

    This paper describes the qualitative effects of LGS spot elongation and Rayleigh scattering on ALFA wavefront sensor images. An analytical model of Rayleigh scattering and a numerical model of laser plume generation at the altitude of the Na-layer were developed. These models, integrated into a general AO simulation, provide the sensor sub-aperture images. It is shown that the centroid measurement accuracy is affected by these phenomena. The simulation was made both for the ALFA system and for the VLT Nasmyth Adaptive Optics System (NAOS).

    The ATLAS ALFA and AFP detectors - the experimental challenge of measuring forward protons at the LHC. We will describe the experimental challenge presented by the measurement of the forward protons at the LHC. The ATLAS ALFA and AFP projects involve the deployment of detectors capable of detecting protons that emerge intact from the interaction with very small scattering angles. In the case of the ALFA detector, located at ±240m from the ATLAS interaction point, this measurement has to be performed using special high \\beta* beam optics. The detector chosen for the task is a nearly edgeless scintillating fibre tracker capable of making measurements at very low t – below 10-3 GeV2 – in the Nuclear Coulomb interference region. In order to reach these very small t-values we need to deploy the detector very near to the beam line utilizing Roman Pots. The main purpose of the ALFA detector is to measure the total p-p cross-section, a fundamental quantity in hadronic physics of importance to particle and to cos...

    The commonalities between the ALICE and FAIR experiments and their computing requirements led to the development of large parts of a common software framework in an experiment independent way. The FairRoot project has already shown the feasibility of such an approach for the FAIR experiments and extending it beyond FAIR to experiments at other facilities[1, 2]. The ALFA framework is a joint development between ALICE Online- Offline (O2) and FairRoot teams. ALFA is designed as a flexible, elastic system, which balances reliability and ease of development with performance using multi-processing and multithreading. A message- based approach has been adopted; such an approach will support the use of the software on different hardware platforms, including heterogeneous systems. Each process in ALFA assumes limited communication and reliance on other processes. Such a design will add horizontal scaling (multiple processes) to vertical scaling provided by multiple threads to meet computing and throughput demands. ALFA does not dictate any application protocols. Potentially, any content-based processor or any source can change the application protocol. The framework supports different serialization standards for data exchange between different hardware and software languages.

    Full Text Available Hideo Orimo Division of Metabolism and Nutrition, Department of Biochemistry and Molecular Biology, Nippon Medical School, Tokyo, Japan Abstract: Hypophosphatasia (HPP is an inherited systemic bone disease that is characterized by bone hypomineralization. HPP is classified into six forms according to the age of onset and severity as perinatal (lethal, perinatal benign, infantile, childhood, adult, and odontohypophosphatasia. The causative gene of the disease is the ALPL gene that encodes tissue-nonspecific alkaline phosphatase (TNAP. TNAP is expressed ubiquitously, and its physiological role is apparent in bone mineralization. A defect in bone mineralization can manifest in several ways, including rickets or osteomalacia in HPP patients. Patients with severe forms suffer from respiratory failure because of hypoplastic chest, which is the main cause of death. They sometimes present with seizures due to a defect in vitamin B6 metabolism resulting from the lack of alkaline phosphatase activity in neuronal cells, which is also lethal. Patients with a mild form of the disease exhibit rickets or osteomalacia and a functional defect of exercise. Odontohypophosphatasia shows only dental manifestations. To date, 302 mutations in the ALPL gene have been reported, mainly single-nucleotide substitutions, and the relationships between phenotype and genotype have been partially elucidated. An established treatment for HPP was not available until the recent development of enzyme replacement therapy. The first successful enzyme replacement therapy in model mice using a modified human TNAP protein (asfotase alfa was reported in 2008, and subsequently success in patients with severe form of the disease was reported in 2012. In 2015, asfotase alfa was approved in Japan in July, followed by in the EU and Canada in August, and then by the US Food and Drug Administration in the USA in October.

    Tumor-draining lymph node cells from mice bearing the methylcholanthrene-induced MCA 106 tumors can be sensitized in vitro to acquire antitumor reactivity. We examined the effect of interferon alfa on the function of cells that underwent in vitro sensitization in adoptive immunotherapy. Interferon alfa increased the antitumor reactivity of in vitro sensitized cells in the treatment of MCA 106 pulmonary metastases. This effect was evident in irradiated mice, indicating that a host response to the interferon alfa was not required. Interferon alfa treatment increased class I major histocompatibility complex antigen expression on tumor cells and increased their susceptibility to lysis by in vitro sensitized cells. These results suggest that interferon alfa enhancement of adoptive immunotherapy was mediated by its effect on tumor cells. Interferon alfa may be a useful adjunct to the adoptive immunotherapy of human cancer.

    The ALFA detector system (Absolute Luminosity For ATLAS) aims for measuring the absolute LHC luminosity with high precision by using pp-scattering under small angles. Scintillating fibers tracking detectors are positioned 240 m from LHC interaction point 1 inside Roman Pots at millimeter distance from the LHC beam axis. The detectors consist of layers of 64 scintillating square fibers of 500 µm size in a U-V configuration. The layers are staggered 10 times to improve the spatial resolution to about 30 micrometers. A total of 11680 scintillating fibers are read out on the 8 ALFA detectors through 184 Multi Anode Photomultiplier Tubes, MAPMTs, of type Hamamatsu R7600-00-M64, 64 channels. Each detector has dedicated scintillating trigger tiles read out by 8 mm Hamamatsu Photomultiplier Tubes (R7400P and R9880U-110) via clear fibers. The gain of the MAPMTs differs up to a factor 3 inside a MAPMT and an additional factor 2 between different MAPMTs. For compensation, ALFA has developed a front-end electronic based...

    Early experience with the operation of the ALFA detectors in the LHC environment has shown significant beam-induced heating. Comprehensive studies on the effects of heating with a spare detector module have furthermore revealed that heating effects could be disastrous in the case of the larger beam intensities foreseen for higher luminosity. A temporary solution was implemented and kept the detectors below the critical temperature in 2012. In LS1 all ALFA stations have been removed from LHC and are undergoing an upgrade of the geometry of Roman Pots to minimize the impedance losses. When the stations were re-installed ~4 m distance was added between them to gain level arm in the angular measurement between the stations. The updated geometry of the Roman Pot, together with a system to improve the internal heat transfer and an air cooling system, is expected to keep the temperatures of ALFA detectors below critical limits throughout the LHC Run2 and first results from the performance in 2016 will be presented. ...

    Full Text Available Anemia is a frequent complication in patients with chronic kidney disease. However, human recombinant erythropoietin (rHu-EPO has revolutionized the management of anemia in chronically dialyzed patients. Epomax ® is a new rHu-EPO alfa manufactured in Tunisia (Medis Laboratories. The aim of this study was to evaluate the efficacy and tolerance of Epomax ® in chronic hemodialysis (HD patients in a phase-III, multicenter, clinical trial. Fiftythree HD patients (mean age 47.7 ± 13 years who received a stable dose of rHu-EPO (Hemax ® , a rHu-EPO alfa manufactured by Biosidus Laboratories subcutaneously were switched to Epomax ® via the same route of administration. At baseline, the mean systolic pressure was 132 ± 18 mm Hg and the mean diastolic pressure was 79 ± 8 mm Hg. The mean blood hemoglobin was 10.2 g/dL and the median ferritin level was 667 ng/mL. After a follow-up of 43 days, the mean blood hemoglobin was 10.5 g/dL under the effect of Epomax ® . There was no significant difference in the mean hemoglobin levels between the treatments with both drugs. Few adverse events were reported during the study. We conclude that Epomax ® was effective at maintaining the hemoglobin levels at target concentrations and was well tolerated in HD patients.

    ABDUL KHALEK, Rabah

    2015-01-01

    We consider a possibility to measure a leading proton momentum using simultaneously the AFP and ALFA detectors. The idea is based on the simple fact that the proton trajectory through the magnetic field between the AFP and ALFA$_{1}$ detectors, depends on the proton's momentum loss $\\xi$. The feasibility of the proton momentum measurement is directly related to the availability of the magnetic fields and their configuration, the overlap between ALFA and AFP detectors and their resolutions as well as energy losses and the multiple scattering effect that could wash away little actions from the magnets on the proton.

    Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising from a population of extragalactic sources, in which case they would provide unprecedented opportunities for probing the intergalactic medium; they may also be linked to new source classes. Until now, however, all so-called fast radio bursts (FRBs) have been detected with the Parkes radio telescope and its 13-beam receiver, casting some concern about the astrophysical nature of these signals. Here we present FRB 121102, the first FRB discovery from a geographic location other than Parkes. FRB 121102 was found in the Galactic anti-center region in the 1.4 GHz Pulsar Arecibo L-band Feed Array (ALFA) survey with the Arecibo Observatory with a DM = 557.4 ± 2.0 pc cm{sup –3}, pulse width of 3.0 ± 0.5 ms, and no evidence of interstellar scattering. The observed delay of the signal arrival time with frequency agrees precisely with the expectation of dispersion through an ionized medium. Despite its low Galactic latitude (b = –0.°2), the burst has three times the maximum Galactic DM expected along this particular line of sight, suggesting an extragalactic origin. A peculiar aspect of the signal is an inverted spectrum; we interpret this as a consequence of being detected in a sidelobe of the ALFA receiver. FRB 121102's brightness, duration, and the inferred event rate are all consistent with the properties of the previously detected Parkes bursts.

    Full Text Available This study aimed to evaluate the rate of sustained virological response (SVR and the clinical and treatment characteristics of patients with chronic hepatitis C (CHC. A retrospective uncontrolled cohort study was conducted among patients who received treatment for CHC between 2005 and 2008 attended at the Center for the Application and Monitoring of Injectable Medications, in Florianopolis, SC, Brazil. The inclusion criteria were: patients over 18 years of age, with a confirmed diagnosis of chronic hepatitis C according to Brazilian guidelines, treated with PEG-IFN alfa-2a or 2b associated with RBV. A total of 188 patients were included in the study: 70% men, 59% genotype 1, 27% coinfected with HIV, 31% with cirrhosis. The SVR rate, calculated by probability theory, was determined as 26% (max=57.4% and min=12.8% and the intention to treat was 12.8%. Associations between Sustained Virological Response (SVR and the variables sex (p=0.017, age (p=0.003, genotype (p=0.648 and cirrhosis (p=0.275, were determined in the bivariate analysis and only sex and age were significantly associated with SVR.

  16. Elosulfase Alfa: a review of its use in patients with mucopolysaccharidosis type IVA (Morquio A syndrome).

    Science.gov (United States)

    Lyseng-Williamson, Katherine A

    2014-10-01

    Elosulfase alfa (Vimizim(®)) is a recombinant form of the human lysosomal enzyme N-acetylgalactosamine-6-sulfatase (GALNS) that is lacking in patients with mucopolysaccharidosis type IVA (MPS IVA; Morquio A syndrome). It is the first, and currently only, disease-specific treatment option for this very rare, progressively degenerative, autosomal-recessive lysosomal storage disorder. Enzyme replacement therapy with elosulfase alfa aims to restore GALNS activity, thereby preventing the accumulation of keratan sulfate (KS) and chondroitin-6-sulfate in lysosomal compartments of cells that results in the clinical manifestations of MPS IVA. In clinical trials in children and adults with MPS IVA, intravenous elosulfase alfa 2 mg/kg/week provided significant and sustained improvements in urinary levels of KS (a pharmacodynamic biomarker for the disease). In the key placebo-controlled, 24-week, phase 3 trial in patients with MPS IVA aged ≥5 years, elosulfase alfa 2 mg/kg/week significantly improved endurance [least squares mean placebo-adjusted change from baseline in 6-min walk test distance 22.5 m (95 % CI 4.0-40.9)]. Infusion-associated reactions, the primary tolerability issue associated with elosulfase alfa, are generally mild to moderate in severity, self-limiting, and manageable. In the absence of a cure, GALNS enzyme replacement therapy with elosulfase alfa is an important achievement in the treatment of MPS IVA.

  17. Agalsidase alfa: a review of its use in the management of Fabry disease.

    2012-10-01

    The enzyme replacement therapy agalsidase alfa (Replagal®) has an amino acid sequence identical to that of native α-galactosidase A; intravenous agalsidase alfa 0.2 mg/kg every other week is indicated for the long-term treatment of patients with confirmed Fabry disease. This article reviews the efficacy and tolerability of agalsidase alfa in patients with Fabry disease, as well as summarizing its pharmacologic properties. Agalsidase alfa had beneficial effects in adult men with Fabry disease, according to the results of two randomized, double-blind, placebo-controlled, 6-month trials (n = 15 and 26). For example, left ventricular mass index was reduced to a significantly greater extent with agalsidase alfa than with placebo. Although the change in myocardial globotriaosylceramide content (primary endpoint in one study) did not significantly differ between agalsidase alfa and placebo recipients, the change in the Brief Pain Inventory (BPI) 'pain at its worst' score (reflecting neuropathic pain while without pain medications; primary endpoint in the second study) was improved to a significantly greater extent with agalsidase alfa than with placebo. In addition, the change in creatinine clearance, but not inulin clearance, significantly favored agalsidase alfa versus placebo recipients. Abnormalities in functional cerebral blood flow and cerebrovascular responses were also reversed with agalsidase alfa therapy. In extensions of these placebo-controlled trials, the reduction in left ventricular mass and improvements in BPI pain scores were maintained after longer-term agalsidase alfa therapy. The significant decline in estimated glomerular filtration rate (eGFR) seen after 48 months' agalsidase alfa treatment was mainly driven by a marked decline in eGFR seen in four patients with stage 3 chronic kidney disease at baseline (although the progression of decline appeared slower than that seen in historic controls); renal function appeared stable in patients with

    AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a "low dose" of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be

    Full Text Available We report the discovery of WTS-2 b, a typical hot Jupiter in an unusually close 1.02-day orbit to a K-dwarf star. This is the second planet to be discovered in the infrared light curves of the WFCAM Transit Survey (WTS and is only one-and-a-half times the separation from its host star at which is would be destroyed by Roche lobe overflow. The predicted remaining lifetime of the planet is just 38 Myrs, assuming a tidal dissipation quality factor of Q'* = 106. The magnitude of Q'* is largely unconstrained by observations, thus WTS-2 b provides a useful calibration point for theories describing how frictional processes within a host star affect the tidal orbital evolution of its companion giant planets. It is expected that stars with large convective envelopes are more efficient at dissipating the orbital energy of the planet, and WTS-2 b provides an observational constraint in the sparsely populated K-dwarf regime. In addition, despite its relatively faint magnitude, the favourable size ratio of the WTS-2 star-planet system and the predicted hot equilibrium temperature of the planet will make it possible to characterise the planet's atmosphere via secondary eclipse measurements using existing ground-based instrumentation.

    The startup of the LHC (Large Hadron Collider) has initialized a new era in particle physics. The standard model of particle physics has for the last 40 years with tremendous success described all measurements with phenomenal precision. The experiments at the LHC will test the standard model in a new energy regime. To normalize the measurements and understand the potential discoveries of the LHC experiments it is often crucial to know the interaction rate - the absolute luminosity. The ATLAS (A Toroidal LHC ApparatuS) detector will measure luminosity by numerous methods. But for most of the methods only the relative luminosity is measured with good precision. The absolute scale has to be provided from elsewhere. Therefore ATLAS plans to measure the flux of protons scattered under very small angles as this flux relates directly and with good precision to the absolute luminosity. This will be done by the ALFA (Absolute Luminosity For ATLAS) detector. The detectors will be positioned about 240 m from the interac...

    Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising from a population of extragalactic sources, in which case they would provide unprecedented opportunities for probing the intergalactic medium; they may also be linked to new source classes. Until now, however, all so-called fast radio bursts (FRBs) have been detected with the Parkes radio telescope and its 13-beam receiver, casting some concern about the astrophysical nature of these signals. Here we present FRB 121102, the first FRB discovery from a geographic location other than Parkes. FRB 121102 was found in the Galactic anti-center region in the 1.4-GHz Pulsar ALFA survey with the Arecibo Observatory with a DM = 557.4 $\\pm$ 3 pc cm$^{-3}$, pulse width of $3\\; \\pm 0.5$ ms, and no evidence of interstellar scattering. The observed delay of the signal arrival time with frequency agrees precisely with the expectation...

    A meta-analysis was conducted of individual patient data (n = 3292) from three randomized controlled trials of corifollitropin alfa versus rFSH: Engage (150 µg corifollitropin alfa n = 756; 200 IU rFSH n = 750), Ensure (100 µg corifollitropin alfa n = 268; 150 IU rFSH n = 128), and Pursue (150 µg corifollitropin alfa n = 694; 300 IU rFSH n = 696). Women with regular menstrual cycles aged 18-36 and body weight >60 kg (Engage) or ≤60 kg (Ensure), or women aged 35-42 years and body weight ≥50 kg (Pursue), received a single injection (100 µg or 150 µg) of corifollitropin alfa (based on body weight and age) or daily rFSH. The difference (corifollitropin alfa minus rFSH) in the number of oocytes retrieved was +1.0 (95% CI: 0.5-1.5); vital pregnancy rate: -2.2% (95% CI: -5.3%-0.9%); ongoing pregnancy rate: -1.7% (95% CI: -4.7%-1.4%); and live birth rate: -2.0% (95% CI: -5.0%-1.1%). The odds ratio for overall OHSS was 1.15 (95% CI: 0.82-1.61), and for moderate-to-severe OHSS: 1.29 (95% CI: 0.81-2.05). A single dose of corifollitropin alfa for the first 7 days of ovarian stimulation is a generally well-tolerated and similarly effective treatment compared with daily rFSH. PMID:27178762

    2010-05-27

    The spectrometer solenoid is supposed to be the first magnets installed in MICE [1]-[4]. This report described what happened during the test of the MICE spectrometer solenoid 2B. First, the report describes the temperatures in the magnet, the cooler top plate and the shield during the run where the magnet quenched at 258 A. During this quench, a lead between the bottom of the HTS leads and the diode bank burned out causing the magnet to quench. Second, three methods for measuring the net heat flow into the cold mass are described. Third, there is a discussion of possible resistive heating in the HTS leads between liquid helium temperature and the copper plate, which is at about 50 K. Fourth, there is a discussion of the measured first stage heat loads in the magnet, when there is no current in the magnet. The first stage heat load calculations are based on knowing the first stage temperatures of the three two-stage pulse tube coolers and the single stage GM cooler. Fifth, the estimated heat load to the first stage when the magnet has current in it is discussed. Sixth, there is a comparison of the stage 1 heat loads in magnet 1A [5], magnet 2A [6], and magnet 2B [7]. Finally there is a discussion of recommended changes for improving the spectrometer solenoids so that the coolers can keep them cold.

En este trabajo postulamos que dicha interacción a nivel genómico sería fundamental para desarrollar respuestas proliferativas mediadas por progestágenos. Demostramos que el antiestrógeno fulvestrant (FUL, ICI182.780 indujo la regresión completa de tumores C4-HD creciendo con MPA. El progestágeno indujo la expresión temprana de CCND1 y MYC en células T47D y este efecto fue revertido al bloquear el REa. En células tratadas con MPA utilizamos ensayos de inmunoprecipitación de la cromatina (ChIP y corroboramos la colocalización nuclear de RP/REa en los mismos sitios de los promotores de CCND1 y MYC. El ICI no afectó la unión de RP a ambas secuencias regulatorias, pero sí inhibió la unión del REa. Confirmamos la interacción nuclear entre REa y RP en muestras de cáncer de mama humano. Los resultados demuestran que la presencia del REa, interactuando con el RP, en promotores de CCND1 y MYC es fundamental para la transcripción génica y la proliferación celular inducida por el progestágeno.

    Darbepoetin alfa is an engineered and hyperglycosylated analog of recombinant human erythropoietin (EPO) which is used as a drug in treating anemia in patients with chronic kidney failure and cancer. This study desribes the secretory expression of a codon-optimized recombinant form of darbepoetin alfa in Leishmania tarentolae T7-TR. Synthetic codon-optimized gene was amplified by PCR and cloned into the pLEXSY-I-blecherry3 vector. The resultant expression vector, pLEXSYDarbo, was purified, digested, and electroporated into the L. tarentolae. Expression of recombinant darbepoetin alfa was evaluated by ELISA, reverse-transcription PCR (RT-PCR), Western blotting, and biological activity. After codon optimization, codon adaptation index (CAI) of the gene raised from 0.50 to 0.99 and its GC% content changed from 56% to 58%. Expression analysis confirmed the presence of a protein band at 40 kDa. Furthermore, reticulocyte experiment results revealed that the activity of expressed darbepoetin alfa was similar to that of its equivalent expressed in Chinese hamster ovary (CHO) cells. These data suggested that the codon optimization and expression in L. tarentolae host provided an efficient approach for high level expression of darbepoetin alfa. PMID:26546410

    Full Text Available This work investigates the effect of hydrothermal aging on the properties of polypropylene/alfa fiber composites. Hydrothermal aging was induced in an environmental testing chamber at 65°C and 75% relative humidity (RH over a 1000 h period. At the beginning (t=0 h, the results showed that Young’s moduli of the untreated alfa fibers and the acetylation-treated fibers increased by 21% and 36%, respectively, compared with the virgin polypropylene (PP. Additionally, Young’s moduli decreased by 7% for the compatibilized composites composed of maleic anhydride grafted polypropylene (MAPP. After 1000 h of aging, Young’s moduli decreased by 36% for untreated alfa fibers and 29% for the acetylation-treated alfa fibers and the compatibilized composites. Significant degradation was observed in the untreated alfa fiber samples. The Fourier transformed infrared (FTIR allows us to distinguish the characteristic absorption bands of the main chemical functions present in the composite material before and after aging. The thermal properties showed that the thermal stability and the degree of crystallinity of the composites decreased after hydrothermal aging; this result was corroborated by the dynamical mechanical analysis (DMA results.

    Full Text Available Fabry disease is an X-linked lysosomal storage disorder caused by inherited deficiency of the enzyme α-galactosidase A. Enzyme replacement treatment using agalsidase alfa significantly reduces pain, improves cardiac function and quality of life, and slows renal deterioration. Nevertheless, it is a life-long treatment which requires regular intravenous infusions and entails a great burden for patients. Our objective was to evaluate retrospectively the safety and tolerability of the home infusion of agalsidase alfa in patients with Fabry disease in Argentina. We evaluated all the patients with Fabry disease who received home infusion with agalsidase alfa 0.2 mg/kg between January 2005 and June 2011. The program included 87 patients; 51 males (mean age: 30 years and 36 females (mean age: 34 years. A total of 5229 infusions (mean: 59 per patient; range: 1-150 were administered. A total of 5 adverse reactions were seen in 5 patients (5.7% of patients and 0.9% of the total number of infusions. All were mild in severity and resolved by reducing the rate of infusion and by using antihistaminics. All these 5 patients were positive for IgG antibodies, but none of them presented IgE antibodies and none suffered an anaphylactic shock. In our group 18 patients were switched from agalsidase beta to agalsidase alfa without complications. Home infusion with agalsidase alfa is safe, well tolerated and is associated to high compliance.

    Full Text Available A partir del conocimiento de la secuenciación del genoma humano es posible el descubrimiento de nuevas terapias, drogas, y causas de enfermedades. Sin embargo, lejos de aumentar el acceso a la atención de la salud, el proyecto genoma humano restringió dicho acceso debido a la rápida comercialización y al creciente ?patentamiento del material humano? -hecho que atenta contra el fundamento ético del sistema jurídico internacional de patentes-.En manos exclusivas de monopolios privados, las ?patentes genéticas? pueden traducirse en altísimos costos de nuevas drogas, tests, y tratamientos para los países en desarrollo. Por lo tanto, si bien la salud humana es presentada como el objetivo último de las investigaciones genómicas, la citada comercialización atenta contra el derecho a la salud y el derecho al conocimiento debido a que imponen una mayor desigualdad y vulnerabilidad de los países en desarrollo por su restricción de acceso. Cabe destacar que es en dichos(países donde se obtiene la información primariaii. En éste nuevo orden internacional de distribución en salud impuesto desde la Organización Mundial de Comercio- OMC- y no desde la Organización Mundial de Salud - OMS-; el actor principal en la ley de patentes, y el beneficiario de la protección que la misma provee, no es ahora el que inventa sino el que invierte.iii Por ello, el objetivo general de la presente investigación es elaborar un marco ético-legal universalista, con especificación plural en ámbitos locales, que regule la investigación del genoma humano en pos de la justa distribución de sus beneficios .

    The nano-VO2 (B) has been self-assembly synthesized by hydrothermal method using different templates, which may give them some interesting properties. The as-prepared samples were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical properties of the samples were investigated. The results show that the hexadecyltrimethyl ammonium bromide (CTAB) (soft template) was used to obtain the VO2 (B1) nanobelts. The flake graphite (hard template) was taken to get the VO2 (B2) nanosheets. The VO2 (B1) nanobelts have higher initial capacity to compare with VO2 (B2). But the VO2 (B2) nanosheets showed better cycling performance than that of VO2 (B1) nanobelts. The nano VO2 (B2) is a promising anode material for lithium ion battery application. PMID:27455666

    Full Text Available Abstract Background Activated drotrecogin alfa (human activated protein C, rhAPC, is produced by recombinant DNA technology, and purports to improve clinical outcomes by counteracting the inflammatory and thrombotic consequences of severe sepsis. Controversy exists around the clinical benefits of this drug and an updated economic study that considers this variability is needed. Methods A systematic literature review was performed using Medline, Embase and the International Network of Agencies for Health Technology Assessment (INAHTA databases to determine efficacy, safety and previous economic studies. Our economic model was populated with systematic estimates of these parameters and with population life tables for longer term survival information. Monte Carlo simulations were used to estimate the incremental cost-effectiveness ratios (ICERs and variance for the decision analytic models. Results Two randomized clinical trials (RCTS of drotrecogin alfa in adults with severe sepsis and 8 previous economic studies were identified. Although associated with statistical heterogeneity, a pooled analysis of the RCTs did not show a statistically significant 28-day mortality benefit for drotrecogin alfa compared to placebo either for all patients (RR: 0.93, 95% CI: 0.69, 1.26 or those at highest risk as measured by APACHE II ≥ 25 (RR: 0.90, 95% CI: 0.54, 1.49. Our economic analysis based on the totality of the available clinical evidence suggests that the cost-effectiveness of drotrecogin alfa is uncertain ( Conclusion The evidence supporting the clinical and economic attractiveness of drotrecogin alfa is not conclusive and further research appears to be indicated.

    Highlights: • PTK2b is expressed in oocytes and is activated following fertilization. • PTK2b suppression in oocytes prevents fertilization, but not parthenogenetic activation. • PTK2b suppression prevents the oocyte from fusing with or incorporating bound sperm. • PTK2b suppressed oocytes that fail to fertilize do not exhibit calcium oscillations. - Abstract: Fertilization triggers rapid changes in intracellular free calcium that serve to activate multiple signaling events critical to the initiation of successful development. Among the pathways downstream of the fertilization-induced calcium transient is the calcium-calmodulin dependent protein tyrosine kinase PTK2b or PYK2 kinase. PTK2b plays an important role in fertilization of the zebrafish oocyte and the objective of the present study was to establish whether PTK2b also functions in mammalian fertilization. PTK2b was activated during the first few hours after fertilization of the mouse oocyte during the period when anaphase resumption was underway and prior to the pronuclear stage. Suppression of PTK2b kinase activity in oocytes blocked sperm incorporation and egg activation although sperm-oocyte binding was not affected. Oocytes that failed to incorporate sperm after inhibitor treatment showed no evidence of a calcium transient and no evidence of anaphase resumption suggesting that egg activation did not occur. The results indicate that PTK2b functions during the sperm-egg fusion process or during the physical incorporation of sperm into the egg cytoplasm and is therefore critical for successful development.

    2012-01-01

    Full Text Available Background: Drugs with complex pharmacology are used in the management of drug use disorder (DUD and HIV/AIDS in Malaysia and in parts of South-East Asia. Their multiethnic populations suggest complexity due to the genetic polymorphism, such as CYP2B6 that metabolizes methadone and anti-retroviral. Aims: Our aim was to explore the genetic polymorphism of CYP2B6 among Malays, Chinese, Indians, and opiate-dependent individuals in Malaysia. Settings and Design: The study utilized DNA from our previous studies on CYPs and new recruitments from opiate-dependent individuals. Materials and Methods: For the new recruitment, after obtaining consent and baseline demography, 5 ml blood was obtained from patients attending methadone maintenance therapy (MMT Clinics. Genomic DNA was extracted using standard methods. 10 nucleotide changes associated with CYP2B6FNx0110, CYP2B6FNx012, CYP2B6FNx0117, CYP2B6FNx0111, CYP2B6FNx018, CYP2B6FNx0114, CYP2B6FNx019, CYP2B6FNx014, CYP2B6FNx016, CYP2B6FNx0127, and CYP2B6FNx0120 were determined using multiplex nested allele-specific PCR. Statistical Analysis: Descriptive statistics were used to summarize demographic data. Differences in allele frequencies between populations were tested using Chi-squared test and were corrected using the Bonferroni test. Results: CYP2B6 polymorphism in Malaysia is variable with trends that suggest an ethnic difference. Reduced activity CYP2B6FNx016 occurred in 13% to 26% among Malays, Chinese, Indians and opiate-dependent individuals. Another ′reduced activity′, CYP2B6FNx012 allele, was found at much lower percentages in the groups. Conclusions: The relative commonness of reduced-activity CYP2B6 alleles in our study called for attention in terms of dosage requirements for MMT and ARV in Malaysia. It also implored follow-up association studies to determine its relevance and consequences in personalized medicine for drug use disorder and HIV/AIDS.

  7. Knockdown of the sodium-dependent phosphate co-transporter 2b (NPT2b suppresses lung tumorigenesis.

    Directory of Open Access Journals (Sweden)

    Seong-Ho Hong

    Full Text Available The sodium-dependent phosphate co-transporter 2b (NPT2b plays an important role in maintaining phosphate homeostasis. In previous studies, we have shown that high dietary inorganic phosphate (Pi consumption in mice stimulated lung tumorigenesis and increased NPT2b expression. NPT2b has also been found to be highly expressed in human lung cancer tissues. The association of high expression of NPT2b in the lung with poor prognosis in oncogenic lung diseases prompted us to test whether knockdown of NPT2b may regulate lung cancer growth. To address this issue, aerosols that contained small interfering RNA (siRNA directed against NPT2b (siNPT2b were delivered into the lungs of K-ras (LA1 mice, which constitute a murine model reflecting human lung cancer. Our results clearly showed that repeated aerosol delivery of siNPT2b successfully suppressed lung cancer growth and decreased cancer cell proliferation and angiogenesis, while facilitating apoptosis. These results strongly suggest that NPT2b plays a role lung tumorigenesis and represents a novel target for lung cancer therapy.

  14. La metafísica de los derechos humanos

    Directory of Open Access Journals (Sweden)

    Carlos Bernal Pulido

    2010-12-01

    Full Text Available Los derechos humanos, en cuanto institución, suscitan interesantes preguntas metafísicas u ontológicas. Las más importantes son qué tipo de entidades componen los derechos humanos, qué propiedades revisten esas entidades y cuál es la estructura con la que dichas propiedades se organizan para conformar tales entidades. Este texto se dedica a responder estos interrogantes pero sólo en cuanto se refiere a la acepción jurídica del término derechos humanos, es decir, entendidos como derechos del individuo garantizados por los sistemas internacionales de protección de los derechos humanos. En este sentido, este texto defiende la tesis de que los derechos humanos son una especie del género derechos jurídicos subjetivos. Los derechos humanos son derechos jurídicos subjetivos cuya differentia specifica estriba en su carácter de “humanos”. La formulación de un concepto de derechos humanos debe pasar, por tanto, primero, por entender el concepto de derechos jurídicos subjetivos y, segundo, por identificar cuáles son las propiedades constitutivas del carácter de “humanos” de los derechos humanos. Este artículo estudia la estructura de los derechos humanos y sus diferentes propiedades formales y materiales. Las propiedades formales son: la inclusión en los instrumentos internacionales sobre derechos humanos y el reconocimiento por parte de la jurisprudencia sobre derechos humanos de los tribunales internacionales especializados. Las propiedades materiales tienen que ver con la relación del derecho con los conceptos de persona propios del Estado liberal, democrático y social. Este texto examina hasta qué punto cada una de estas propiedades debe considerarse como una propiedad necesaria, suficiente o necesaria y suficiente para que un derecho sea considerado como un derecho humano.

  17. Correlation between mechanical and dielectric properties of Alfa/Wool/Polymeric hybrid fibres reinforced polyester composites

    International Nuclear Information System (INIS)

    Dielectric measurements and tensile testing of polyester/natural fibres (Alfa/wool) and thermo binder fibres (Pe/Pet) composites were investigated in order to study the adhesion of the fibres in the polyester matrix. Two composites #1 and #2 having 17:1:2 and 17:2:1 as a relative fraction of alfa/wool and thermo binder (Pe/Pet), respectively, have been characterized in this study. The obtained results revealed that the fibres adhesion in the matrix was better in the composite #1 than in the composite #2. Indeed, the analysis of the interfacial or Maxwell-Wagner-Sillars (MWS) polarization intensity, using the Havriliak–Negami model, has shown a lower intensity and the tensile testing exhibited a higher Young modulus in the composite #1. So the thermo binder fibres improve this adhesion

  18. Managing infertility with the follitropin alfa prefilled pen injector - patient considerations.

    Bühler, Klaus

    2015-01-01

    Gonadotropin treatment has been used in fertility treatment since the 1930s. First, preparations coming from animals were injected, then, gonadotropins prepared from the pituitary glands of human cadavers. A great step was achieved with the introduction of human menopausal gonadotropin extracted from the urine of postmenopausal women. When cases of Creutzfeld-Jacob disease were recognized after the use of human pituitary-derived hormone injections, urinary gonadotropins were increasingly purified and then produced by the use of recombinant DNA technology. Recombinant gonadotropins were characterized by the extreme high specificity and the nearly 100% purity. This allows for follitropin alfa, the first recombinant-human follicle stimulating hormone (r-hFSH) approved, to be quantified and filled by mass, with a small variance of only ±2% and no more with a bioassay with a variance of 45%. With recombinant preparations, it is also possible to cover the tremendous growing demand for gonadotropins. Ovarian stimulation has become a self-injecting procedure for the patients. Accurate and easy-to-use injection devices which minimize pain, difficulty, and stress are essential for patient compliance. So, two pen injectors adapted from the well-known insulin pen were introduced in fertility treatment, one as a multiple-use device rechargeable with premixed, prefilled cartridges with r-hFSH (follitropin β) and the other a disposable, prefilled drug delivery system with a liquid formulation of follitropin alfa filled by mass. The efficacy in comparison to the quite more cumbersome handling with ampoules and syringes has been proven very quickly. In several studies, it has been shown that patients had a preference to the prefilled follitropin alfa pen due to the faster preparation and were more confident of accurate dosing. The follitropin alfa (filled by mass [FbM]) prefilled pen is a move toward better quality of treatment and also better quality of life for the women within

    Full Text Available Background: Biofeedback is a technique in which people are trained to improve their health by learning to control certain internal bodily processes that normally occur involuntarily. Various studies in the past have shown usefulness of Alfa electroencephalographic (EEG biofeedback in the alleviation of anxiety symptoms. Though most of the psychiatric centers in the armed forces have this facility, not much work has been done in our setup to assess its efficacy in the management of anxiety. Hence this study was undertaken. Materials and Methods: This study was carried out in a multispecialty Command Hospital by enrolling 100 patients with psychiatric diagnosis from both inpatient and outpatient services. The anxiety level was assessed clinically and by using Hamilton Anxiety Scale and Taylor′s Manifest Anxiety Scale. One group of 50 patients was treated with Alfa EEG biofeedback sessions only, 5 times in a week for 8 weeks, along with specific pharmacotherapy. The other group was treated with appropriate dose of anxiolytics. The anxiety level was reassessed after 4 weeks and 8 weeks. Results: The response was better for mixed anxiety and depressive disorder with pharmacotherapy than with the biofeedback, but female patients showed better response with EEG biofeedback. Conclusion: In the short term, Alfa EEG biofeedback therapy is almost as efficacious as pharmacological intervention in the management of anxiety symptoms, and relatively more useful in females.

    Full Text Available Nanocellulose (NC were extracted from the Moroccan Alfa plant (Stipa tenacissima L. and characterised. These Alfa cellulosic nanoparticles were used as reinforcing phase to prepare bionanocomposite films using carboxymethyl cellulose as matrix. These films were obtained by the casting/evaporation method. The crystallinity of NC was analysed by X-ray diffraction, the dimension of NC by atomic force microscopy, molecular interactions due to incorporation of NC in carboxymethyl cellulose (CMC matrix were supported by Fourier transforms infrared (FTIR spectroscopy. The properties of the ensuing bionanocomposite films were investigated using tensile tests, water vapour permeability (WVP study and thermogravimetric analysis. With the progress of purification treatment of cellulose, the crystallinity is improved compared to the untreated fibres; this can be explained by the disappearance of the amorphous areas in cellulose chain of the plant. Consequently, the tensile modulus and tensile strength of CMC film increased by 60 and 47%, respectively, in the bionanocomposite films with 10 wt% of NC, and decrease by 8.6% for WVP with the same content of NC. The NC obtained from the Moroccan Alfa fibres can be used as a reinforcing agent for the preparation of bionanocomposites, and they have a high potential for the development of completely biodegradable food packaging materials.

    In preparation for the full Arecibo Legacy Fast ALFA extragalactic HI survey, precursor observations were carried out in Aug--Sep 2004 with the 7-beam Arecibo L-band feed array (ALFA) receiver system and the WAPP spectral processors. While these observations were geared mainly at testing and debugging survey strategy, hardware and software, approximately 36 hours of telescope time yielded science--quality data. From those observations, an initial list of 730 tentative detections of varying degree of reliability was extracted. Ninety--eight high signal-to-noise candidates were deemed to be bona fide HI line detections. To test our ability to discriminate cosmic signals from RFI and noise, 165 candidates ranging in reliability likelihood were re--observed with the single beam L--band wide system at Arecibo in Jan--Feb 2005. Of those, 41% were confirmed as real. We present the results of both the ALFA and single beam observations for the sample of 166 confirmed HI sources, as well as our assessment of their opti...

El ser humano es un ser singular. En él que conviven dos dimensiones de distinta naturaleza, una material y otra espiritual, y precisamente esta es la principal de las diferencias entre el hombre y el resto de seres vivos. Pero además en el hombre aparece una nueva característica, única entre los seres vivos, la componente ética. Los valores y pautas del comportamiento moral y ético del ser humano deben considerarse de origen natural ya que han contribuido al éxito y supervivencia de la especie. El hombre no es solo Homo sapiens sino también Homo moralis. El reconocimiento de culpa, autodominio, solidaridad, amor, generosidad, altruismo y honestidad, entre otras, son cualidades innatas en los seres humanos. La antropología filosófica destaca el carácter único e irrepetible propio de cada ser humano, cada persona. Esto coincide plenamente con los datos de la ciencia, que destaca la identidad genética individual y singular de cada ser humano.

    Full Text Available Introduction Hepatitis C virus infection is a slowly progressive chronic disease and the most common cause of chronic liver disease. Presently, interferon alfa based therapies, with or without ribavirin, are standard treatment for chronic hepatitis C virus infection. The most troublesome psychiatric side effects of interferon therapy in our patients are: insomnia, irritability, anxiety, mood changes, short temper, emotional and affective lability, impaired cognitive function, apathy, loss of motivation and the most serious depression with or without suicidal ideas. Material and methods In our study we treated 82 patients chronically infected with HCV divided into 3 groups: the first group of 31 patients (20 male and 11 female received IFN-alfa in standard doses of 3 MU three times a week (t.i.w during 24 weeks; the second group of 36 patients (25 male and 11 female received IFN-alfa, 3 MU t.i.w plus ribavirin 1000-1200 mg per day during 24 weeks; the third group of 15 patients (11 male and 4 female received IFN-alfa, 3 MU t.i.w plus ribavirin 1000-1200 mg per day during 48 weeks. The follow-up period after therapy in all groups lasted 24 weeks. Results During treatment, we observed at least one psychiatric side effect in 21 (26% patients: insomnia in 11 (13%, emotional and affective lability in 9 (11%, anxiety, irritability and short temper in 8 (10%, impaired cognitive function in 7 (8% apathia and loss of motivation in 6 (7% treated patients.

    A selective, high-affinity A(2B) adenosine receptor (AR) antagonist will be useful as a pharmacological tool to help determine the role of the A(2B)AR in inflammatory diseases and angiogenic diseases. Based on early A(2B)AR-selective ligands with nonoptimal pharmaceutical properties, such as 15 (MRS 1754: K(i)(hA(2B)) = 2 nM; K(i)(hA(1)) = 403 nM; K(i)(hA(2A)) = 503 NM, and K(i)(hA(3)) = 570 nM), several groups have discovered second-generation A(2B)AR ligands that are suitable for development. Scientists at CV Therapeutics have discovered the selective, high-affinity A(2B)AR antagonist 22, a 8-(4-pyrazolyl)-xanthine derivative, (CVT-6883, K(i)(hA(2B)) = 22 nM; K(i)(hA(1)) = 1,940 nM; K(i)(hA(2A)) = 3,280; and K(i)(hA(3)) = 1,070 nM). Compound 22 has demonstrated favorable pharmacokinetic (PK) properties (T(1/2) = 4 h and F > 35% rat), and it is a functional antagonist at the A(2B)AR(K (B) = 6 nM). In a mouse model of asthma, compound 22 demonstrated a dose-dependent efficacy supporting the role of the A(2B)AR in asthma. In two Phase I clinical trails, 22 (CVT-6883) was found to be safe, well tolerated, and suitable for once-daily dosing. Baraldi et al. have independently discovered a selective, high-affinity A(2B)AR antagonist, 30 (MRE2029F20), 8-(5-pyrazolyl)-xanthine (K(i)(hA(2B)) = 5.5 nM; K(i)(hA(1)) = 200 nM; K(i)(hA(2A), A(3)) > 1,000, that has been selected for development in conjunction with King Pharmaceuticals. Compound 30 has been demonstrated to be a functional antagonist of the A(2B)AR, and it has been radiolabeled for use in pharmacological studies. A third compound, 58 (LAS-38096), is a 2-aminopyrimidine derivative (discovered by the Almirall group) that has high A(2B)AR affinity and selectivity (K(i)(hA(2B)) = 17 nM; K(i)(hA(1)) > 1,000 nM; K(i)(hA(2A)) > 2,500; and K(i)(hA(3)) > 1,000 nM), and 58 has been moved into preclinical safety testing.

Tomando a Declaração Universal dos Direitos do Homem, de 1948, como base e ponto de partida, o articulista aborda as três principais vertentes dos sistemas de promoção desses direitos: a européia, a americana e a africana. A evolução de cada uma delas descrita analógica e epistemologicamente, de forma a salientar singularidades sem perder de vista as influências recíprocas ou mesmo as determinantes próprias do contexto espaço-social. Para finalizar, o articulista destaca a importância do Tribunal Penal Internacional no estabelecimento de uma justiça ecumênica. Concomitantemente, alerta para o perigo contido na ameaça de os EUA não o ratificarem.The text underlines the institutional character acquired by the main systems to promote Human Rights in the twentieth century. Taking the Universal Human Rigths Declaration, of 1948, as the basis for analysis, the author brings up three different approaches to promote these rights: the European, the American and the African. The evolution of each of them is described using its procedure as a basic reference. Besides, an analogical analysis, brings to the fore singularities, without ignoring reciprocal influences dictated by particular contexts, though. The author stresses the importance of the International Penal Court, as a means to establish ecumenical justice. At the same time, he reminds the reader of the risks implicit in the possible non-ratification of the IPC by United States.

    Full Text Available Es necesario superar el discurso sobre el SER y la Existencia para adentrarse en un camino práctico, que redescubre el dinamismo de la existencia de la persona humana como presencia encarnada del SER. Guiados por las palabras del místico Maestro Eckhart de Hochheim se redescubre al SER como Principio y Fundamento de la esencia de la perso- na, (SER al que buena parte de la humanidad ha llamado “Dios”, que por medio de diversas ma- nifestaciones percibidas a nivel psicológico, parece llamarlo al reencuentro. Por esto conviene ampliar la mirada para releer manifestaciones tales como la ansiedad y los estados emocionales incomprendidos por quienes los padecen y que la medicina tradicio- nal los trata como situaciones estáticas, como signos de un proceso dinámico en el alma. Así es nece- saria una psicología del Camino Interior durante el proceso que la persona realiza hasta acceder al Ser esencial. Este Camino Interior incluye la liberación de la dictadura de las emociones y de otras dolencias del alma. Finaliza este artículo con una anotación a una práctica que puede orientar hacia dónde dirigir la mirada cuando se opta por el Camino Interior; la práctica del sentarse, como no-acción y recogimien- to interior, el vivir con plena atención y mantener la respiración correcta, como se practica en muchos monasterios, que además de alejar del activismo y el frenesí de la cotidianidad, abre las puertas para el descubrimiento interior del ser humano como SER hecho Existencia

  3. The FRCR 2B oral examination: Is it reliable?

    International Nuclear Information System (INIS)

    Aim: To investigate the reliability of the oral component of the Fellowship of the Royal College of Radiologists (FRCR) 2B examination. Materials and methods: Anonymized candidate test scores were analysed from nine consecutive sittings of the FRCR 2B oral examination covering the period from spring 2006 to spring 2010. Interobserver reliability was assessed using weighted Kappa coefficient, intraclass correlation coefficient, and a modified Bland–Altman plot. Results: During the study period, 2235 candidates sat the FRCR 2B examination. Eighty-five point one percent of candidates obtained paired oral assessment scores within one mark of each other. This figure rises to 95.7% for paired scores within 1.5 marks of each other. Mean difference in scores was 0.67 (95% CI: 0.65–0.70). Agreement rises at the extremities of mean score. Reliability coefficients for the FRCR 2B oral examination were calculated as 0.27 (weighted Kappa) and 0.44 (intraclass correlation coefficient). Conclusion: The calculated reliability coefficients indicate fair to, at best, moderate interobserver reliability in the FRCR 2B oral examination. These findings are disappointing but are comparable with other oral assessment reliability studies. There is scope for improvement, although further work to measure the combined reliability of all the components of the FRCR 2B examination is desirable. Measures that could potentially increase reliability must be carefully considered against any negative impact on test validity, acceptability, and cost

    Inducible nitric oxide synthase (NOS2) catalyzes the production of nitric oxide (NO), and is one of the factors establishing innate immunity. In zebrafish, Nos2 is represented by nos2a and nos2b. Here, we report the cloning and expression pattern of the zebrafish nos2b gene, which does not seem to participate in induced immune response. nos2b was mapped to zebrafish linkage group 15. The spatial and temporal expression pattern of nos2b in embryonic zebrafish was analyzed by whole-mount in situ hybridization. nos2b is expressed constitutively in two primordia located along the ventral midline. The first group of cells contributes to the neurohypophysis. Initially at the level of the ventral hindbrain, the second group of cells migrates closely with the thyroid primordium to its final position at the basihyal by 3 dpf. Thus, the analysis of expression pattern of nos2b reveals complex morphogenetic movements resulting in its expression surrounding the oral cavity.

Knowing that the high dilution of substances can have an inverted effect, our hypotesis was that dillution made of TNF-alfa can decrease the clinical manifestation of such diseases. Materials and method: We included as a pilot group 10 patients presented in Lotus Life Integrative Medicine Center or Profamilia Medical Center Iasi with psoriasis and rheumatoid arthritis previously diagnosed by specialists, under speciality treatment with insufficient results and patients who deliberately expressed their preference for alternative treatment. We decided to exclude the patients which during the study could present aggravation of symptoms. The treatment protocol consisted in the administration under the tongue of the dilution of TNF-alfa 9CH in liquid form, 12 drops twice a day for at least 3 months. This was prepared diluting from Guna TNF-alfa 4CH in distiled water, completing with 30% of alcohol in the last solution. Patients under other medications continued to take their previous treatment unchanged. We called the patients for follow-up after 3 months. We took the written consent from the patients and the approval of the Ethical Committee of the University of Medicine and Pharmacy "Gr. T. Popa" of Iasi. Results: To analize the results we followed the subjective evolution of the patients, the total surface and thickness of eruptions in psoriasis patients and the pain intensity and stiffness in arthritis patients. Under this conditions, all the patients showed amelioration, with 2 out of 6 psoriasis patients showing complete clearance of eruptions. No patient reported adverse reactions during the treatment Conclusions: Even though the group of patients was small and not appropriate for statistical data the presence of a clinical

    Over last few decades, hepatitis C has emerged as a serious infection that has threatened the health and budgets of millions in the world. The objective of health professionals to treat it with recommended therapy of Alfa interferon and Ribavirin combination presents certain risks. One of the alarms is the ability of interferon to stimulate the production of autoantibodies in the body resulting in expression of autoimmune diseases in few who develop these antibodies. The case presented here is about unmasking of myasthenia gravis in a patient who received alfa interferon therapy for her chronic hepatitis C. Alfa interferon probably plays an important role in manifestation of the diseases in susceptible patients and all autoimmune diseases cannot be taken as mere side effects of the therapy. Clinicians need to be alert to pick up these diseases earlier so that the prompt management is possible. PMID:27183950

    2015-01-01

    FAIR is a new, unique international accelerator facility for the research with antiprotons and ions. It is being built at the GSI Darmstadt in Hesse, Germany. The commonalities between the ALICE and FAIR experiments and their computing requirements led to the development of a common software framework in an experiment independent way; ALFA (ALICE-FAIR framework). ALFA is designed for high quality parallel data processing and reconstruction on heterogeneous computing systems. It provides a data transport layer and the capability to coordinate multiple data processing components. ALFA is a flexible, elastic system which balances reliability and ease of development with performance by using a message based multi-processing in addition to multi-threading. The framework allows for usage of heterogeneous computing architectures by offloading (portions of code are accelerated on the device) or natively (where the full program is executed on the device ).

    Radio observations of gas in the Milky Way and Local Group are vital for understanding how galaxies function as systems. The unique sensitivity of Arecibo's 305m dish, coupled with the 7-beam Arecibo L-Band Feed Array (ALFA), provides an unparalleled tool for investigating the full range of interstellar phenomena traced by the HI 21cm line. The GALFA (Galactic ALFA) HI Survey is mapping the entire Arecibo sky over a velocity range of -700 to +700 km/s with 0.2 km/s velocity channels and an angular resolution of 3.4 arcminutes. We present highlights from the TOGS (Turn on GALFA Survey) portion of GALFA-HI, which is covering thousands of square degrees in commensal drift scan observations with the ALFALFA and AGES extragalactic ALFA surveys.

  11. Managing infertility with the follitropin alfa prefilled pen injector – patient considerations

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Klaus Bühler Centre for Gynaecological Endocrinology and Reproductive Medicine, Stuttgart, Germany Abstract: Gonadotropin treatment has been used in fertility treatment since the 1930s. First, preparations coming from animals were injected, then, gonadotropins prepared from the pituitary glands of human cadavers. A great step was achieved with the introduction of human menopausal gonadotropin extracted from the urine of postmenopausal women. When cases of Creutzfeld-Jacob disease were recognized after the use of human pituitary-derived hormone injections, urinary gonadotropins were increasingly purified and then produced by the use of recombinant DNA technology. Recombinant gonadotropins were characterized by the extreme high specificity and the nearly 100% purity. This allows for follitropin alfa, the first recombinant-human follicle stimulating hormone (r-hFSH approved, to be quantified and filled by mass, with a small variance of only ±2% and no more with a bioassay with a variance of 45%. With recombinant preparations, it is also possible to cover the tremendous growing demand for gonadotropins. Ovarian stimulation has become a self-injecting procedure for the patients. Accurate and easy-to-use injection devices which minimize pain, difficulty, and stress are essential for patient compliance. So, two pen injectors adapted from the well-known insulin pen were introduced in fertility treatment, one as a multiple-use device rechargeable with premixed, prefilled cartridges with r-hFSH (follitropin β and the other a disposable, prefilled drug delivery system with a liquid formulation of follitropin alfa filled by mass. The efficacy in comparison to the quite more cumbersome handling with ampoules and syringes has been proven very quickly. In several studies, it has been shown that patients had a preference to the prefilled follitropin alfa pen due to the faster preparation and were more confident of accurate dosing. The follitropin alfa

    2016-06-01

    Rap2B GTPase, a member of Ras-related protein superfamily, was first discovered from a platelet cDNA library in the early 1990s. Since then, it has been reported to play an important role in regulating cellular processes including cytoskeletal organization, cell growth, and proliferation. It can be stimulated and suppressed by a wide range of external and internal inducers, circulating between GTP-bound active state and GDP-bound inactive state. Increasing focus on Ras signaling pathway reveals critical effects of Rap2B on tumorigenesis. In particular, Rap2B behaves in a p53-dependent manner in regulation of apoptosis and migration. Apart from being an oncogenic activator, Rap2B has been found to participate in many other physiological events via diverse downstream effectors. In this review, we present recent studies on the structure, regulation, and multiple biological functions of Rap2B, shedding light on its potential status in treatment of cancer as well as other diseases.

  7. Substrate Recognition of Histone H2B by DUBm

    Science.gov (United States)

    Henderson, Elizabeth; Berndsen, Christopher; Wolberger, Cynthia

    2011-03-01

    The SAGA complex is a transcriptional coactivator that regulates gene expression in eukaryotes via histone acetylation and deubiquitination, which are crucial for transcription. Our lab is investigating the SAGA-dependent deubiquitination of histone H2B. The deubiquitinating module (DUBm) of SAGA is comprised of a ubiquitin-specific protease, Ubp8, and three other proteins. It is known that Ubp8 cleaves ubiquitin from histone H2B, however, the specific way in which the enzyme binds to the substrate remains elusive. In order to unravel this mechanism, we attempted to determine the crystal structure of the substrate binding complex. We obtained this substrate by exploiting the techniques of intein chemistry to artificially ubiquitinate a histone H2B peptide, which we then co-crystallized with DUBm. Additionally, we synthesized Ub-K63R-linked chains and Ub-K48-linked chains and co-crystallized them with DUBm.

    The percentage of infested mango fruits of five selected mango varieties was evaluated during three years under field conditions. Three varieties with field resistance to fruit flies had less then 10% of fruits infested. Tommy Atkins, the susceptible commercial check, had 42,9% and the susceptible check had 98.9 % of infested fruits. The three field resistant varieties plus the susceptible commercial check, Tommy Atkins, were further tested in laboratory, under caged conditions, with artificial infestation of Anastrepha obliqua. The attempts of oviposition and the number of pupae developed from each fruit were evaluated. Under caged conditions, the cultivar Alfa maintained its field resistance and Espada Stahl and IAC 111 lost the field resistance and were as susceptible as Tommy Atkins. The attempts of oviposition were positively and highly correlated with the number of pupae developed in the fruits. Non preference for oviposition was confirmed as the main mechanism of resistance of mango fruits to fruit flies. In the absence of a more susceptible variety (no choice test) the cultivar Alfa has kept the resistance (author)

    A special week-long proton–proton run with larger beam sizes at the interaction point is intended to probe the p-p elastic scattering regime at small angles.   Nicola Turini, deputy spokesperson for TOTEM, in front of one of the experiment’s ‘Roman Pot’ detectors in the LHC tunnel. (Photo: Maximilien Brice/CERN) Usually, the motto of the LHC is “maximum luminosity”. But for a few days per year, the LHC ignores its motto to run at very low luminosity for the forward experiments. This week, the LHC will provide the TOTEM and ATLAS/ALFA experiments with data for a broad physics programme. The TOTEM experiment at Point 5 and the ATLAS/ALFA experiment at Point 1 study the elastic scattering of protons, which are not observable in normal operation runs. In the elastic scattering process, the two protons survive their encounter intact and only change directions by exchanging momentum. To allow this special run, the operators play with the so-c...

  14. Neuropsychiatric side-effects of interferon alfa therapy for hepatitis C and their management: A review

    2006-01-01

    Full Text Available Background:Interferon-Alfa (IFN-α has been the mainstay of treatment for chronic hepatitis C. It has the potential to alter the course of chronic hepatitis C and prevent complications. Aims: This review summarizes current knowledge about the presentation, mechanism, course, and treatment of neuropsychiatric problems associated with interferon alfa (IFN-α treatment. Methods: Studies were identified by computerized searches, and further references were obtained from bibliographies of the reviewed articles. Results: Neuropsychiatric symptoms frequently occur in hepatitis C patients treated with IFNAlfa. These side effects are troublesome and frequently account for dose reduction or treatment discontinuation. Sometimes, they could be serious and possibly life threatening. Frequent psychiatric evaluations of high risk individuals and, when required, early administration of antidepressants could possibly help to avoid the development of an impending depression or reduce its severity and duration and thus increase adherence to treatment. Conclustion: Greater cooperation between psychiatrists and hepatologists would mean less risk of having the serious side effects with more importance needs to be given to the identification of patients at risk.

    We have conducted a deep, complete HI survey, using Arecibo/ALFA, of a field centered on the nearby, isolated galaxy, NGC 2903, which is similar to the Milky Way in its properties. The field size was 150 kpc x 260 kpc and the final velocity range spanned from 100 to 1133 km/s. The ALFA beams have been mapped as a function of azimuth and cleaned from each azimuth-specific cube prior to forming final cubes. The final HI data are sensitive down to an HI mass of 2 x 10^5 Mo and column density of 2 x 10^{17} cm^{-2} at the 3sigma x 2deltaV level, where sigma is the rms noise level and deltaV is the velocity resolution. NGC 2903 is found to have an HI envelope that is larger than previously known, extending to at least 3 times the optical diameter of the galaxy. Our search for companions yields one new discovery with an HI mass of 2.6 x 10^6 Mo. The companion is 64 kpc from NGC 2903 in projection, is likely associated with a small optical galaxy of similar total stellar mass, and is dark matter dominated, with a to...

  16. Drotrecogin alfa (activated)...a sad final fizzle to a roller-coaster party.

    Angus, Derek C

    2012-01-01

    Following the failure of PROWESS-SHOCK to demonstrate efficacy, Eli Lilly and Company withdrew drotrecogin alfa (activated) from the worldwide market. Drotrecogin was initially approved after the original trial, PROWESS, was stopped early for overwhelming efficacy. These events prompt consideration of both the initial approval decision and the later decision to withdraw. It is regrettable that the initial decision was made largely on a single trial that was stopped early. However, the decision to approve was within the bounds of normal regulatory practice and was made by many approval bodies around the world. Furthermore, the overall withdrawal rate of approved drugs remains very low. The decision to withdraw was a voluntary decision by Eli Lilly and Company and likely reflected key business considerations. Drotrecogin does have important biologic effects, and it is probable that we do not know how best to select patients who would benefit. Overall, there may still be a small advantage to drotrecogin alfa, even used non-selectively, but the costs of determining such an effect with adequate certainty are likely prohibitive, and the point is now moot. In the future, we should consider ways to make clinical trials easier and quicker so that more information can be available in a timely manner when considering regulatory approval. At the same time, more sophisticated selection of patients seems key if we are to most wisely test agents designed to manipulate the septic host response. PMID:22309988

    2004-01-01

    While XML web services become recognized as a solution to business-to-business transactions, there are many problems that should be solved. For example, it is not easy to manipulate business documents of existing standards such as RosettaNet and UN/EDIFACT EDI, traditionally regarded as an important resource for managing B2B relationships. As a starting point for the complete implementation of B2B web services, this paper deals with how to support B2B business documents in XML web services. In the first phase, basic requirements for driving XML web services by business documents are introduced. As a solution, this paper presents how to express B2B business documents in WSDL, a core standard for XML web services. This kind of approach facilitates the reuse of existing business documents and enhances interoperability between implemented web services. Furthermore, it suggests how to link with other conceptual modeling frameworks such as ebXML/UMM, built on a rich heritage of electronic business experience.

    Full Text Available Business to Business (B2B Internet commerce causes a significant contraction of transaction costs. According to the Coase paradigm, we would thus expect a deverticalization of the industry and broader scope for anonymous market mechanisms. In reality, such expectations are not fully borne out by the facts. When the industrial structure is concentrated the B2Bgenerally loses its independence, and is owned by the firms which most contribute to its development, e.g. the ones able to bring the liquidity to it. The B2B governance mechanism established by these firms gives hierarchical mechanisms a role which they do not usually play in extensive, anonymous markets.

    Full Text Available Se revisará la cuestión referida al sentido, el valor y el desarrollo de los derechos humanos en el contexto actual. Se tratará de conocer el lugar y papel que ocupa el sujeto, su autonomía y su condición de ciudadano en las democracias modernas. Se anticipa como hipótesis que, en relación al proceso de enseñanza y aprendizaje, será importante perseguir un triple objetivo centrado en el saber pensar, el saber seleccionar y el saber hacer. Otro aspecto fundamental será el de la exclusión social, tratada aquí como el lado negativo de los derechos humanos y del desarrollo. Se concluye que la existencia de los derechos humanos reclama un compromiso ético integrando la búsqueda simultánea de la igualdad, esto es, del reconocimiento del ‘otro’ en su autonomía y diversidad como sujetos de derecho y con derechos. De ahí la necesidad de educar para los derechos, que significa educar para los derechos del ‘otro’, para los derechos como instrumento de convivencia entre sujetos libres, para los derechos individuales y también para la conciencia del valor de los derechos colectivos.

    Full Text Available El reconocimiento de la importancia de las personas en el desarrollo de las organizaciones, especialmente por la posibilidad de construir ventaja competitiva fundamentada en el talento humano, está demandando de quienes lideran el área de recursos humanos el desarrollo de competencias que respondan a los nuevos retos. La revisión de investigaciones realizadas sobre el tema en otras latitudes permite concluir que existen diferentes tipologías de competencias para los profesionales del área de recursos humanos, que no existen estudios específicos de competencias para los gerentes del área y que se puede construir un modelo de competencias a través de análisis cualitativos. Estas consideraciones motivaron la presente investigación, que contó con el apoyo de la Asociación Colombiana de Gestión Humana (ACRIP. Se utilizó una metodología hermenéutica mediante la aplicación de entrevistas de eventos conductuales y de mapa funcional. Los resultados se reflejan en un modelo que comprende cuatro categorías y 18 competencias, además de los valores de los gerentes de talento humano y el diccionario de competencias.

    Cobalt boride (Co$_2$B) is a significant transition metal boride having a wide range of usage area due to its high oxidation, abrasion and corrosion resistance as well as its superior electrochemical, magnetic and anisotropicproperties. In this study, pure Co2B nanocrystals were synthesized with Co, B$_2$O$_3$ and Mg as starting materials via the mechanochemical synthesis (MCS) method by high-energy planetary ball mill in a hardened steel vial withhardened steel balls. All the experiments were conducted under Ar atmosphere at different rotational speeds and at 20:1–30:1–40:1 ball-to-powder ratios. Leaching of Co$_2$B $+$ MgO powder mixtures occurred after milling andpurified with acetic acid and pure Co$_2$B nanocrystals were obtained in solid form. The Co2Bs were characterized through X-ray diffraction, scanning electronmicroscopy, vibrating samplemagnetometer, Brunauer–Emmett–Tellerand specific density analyses, and effects of synthesis parameters on product properties were revealed. Surface areas of the powders synthesized at 40:1 ball-to-powder ratio at different rotational speeds were measured as 21.14,40.36 and 52.33 m$^2$ g$^{−1}$, respectively. Crystallite sizes of Co$_2$B nanocrystals were between 7.27 and 9.84 nm and their specific density varied between 7.61 and 7.78 g cm$^{−3}$. It was determined that all samples were saturated and exhibited hysteresis and ferromagnetic behaviours, and saturation magnetization was between 35 and 50 emu g$^{−1}$.

    Accurate whole-brain segmentation, or brain extraction, of magnetic resonance imaging (MRI) is a critical first step in most neuroimage analysis pipelines. The majority of brain extraction algorithms have been developed and evaluated for adult data and their validity for neonatal brain extraction, which presents age-specific challenges for this task, has not been established. We developed a novel method for brain extraction of multi-modal neonatal brain MR images, named ALFA (Accurate Learning with Few Atlases). The method uses a new sparsity-based atlas selection strategy that requires a very limited number of atlases ‘uniformly’ distributed in the low-dimensional data space, combined with a machine learning based label fusion technique. The performance of the method for brain extraction from multi-modal data of 50 newborns is evaluated and compared with results obtained using eleven publicly available brain extraction methods. ALFA outperformed the eleven compared methods providing robust and accurate brain extraction results across different modalities. As ALFA can learn from partially labelled datasets, it can be used to segment large-scale datasets efficiently. ALFA could also be applied to other imaging modalities and other stages across the life course.

    Turoctocog alfa (NovoEight) is a third-generation recombinant factor VIII (rFVIII) with a truncated B-domain that is manufactured in Chinese hamster ovary cells. No human or animal-derived materials are used in the process. The aim of this study is to describe the molecular design and purification process for turoctocog alfa. A five-step purification process is applied to turoctocog alfa: protein capture on mixed-mode resin; immunoaffinity chromatography using a unique, recombinantly produced anti-FVIII mAb; anion exchange chromatography; nanofiltration and size exclusion chromatography. This process enabled reduction of impurities such as host cell proteins (HCPs) and high molecular weight proteins (HMWPs) to a very low level. The immunoaffinity step is very important for the removal of FVIII-related degradation products. Manufacturing scale data shown in this article confirmed the robustness of the purification process and a reliable and consistent reduction of the impurities. The contribution of each step to the final product purity is described and shown for three manufacturing batches. Turoctocog alfa, a third-generation B-domain truncated rFVIII product is manufactured in Chinese hamster ovary cells without the use of animal or human-derived proteins. The five-step purification process results in a homogenous, highly purified rFVIII product.

    Full Text Available Sepsis can be defined as a spectrum of clinical conditions caused by the immune response of a host to infection or trauma and characterized by systemic inflammation and coagulation. Particularly in elderly, immunocompromised and critically ill patients, sepsis is a major cause of morbidity and mortality in intensive care units (ICUs worldwide. In the US, sepsis is the leading cause of death in noncoronary ICU patients. Drotrecogin alfa, or recombinant human activated protein C, has antithrombotic, antiinflammatory, and profibrinolytic properties. Recently in a phase III trial (PROWESS, Drotrecogin alfa demonstrated significantly reduced mortality in severe sepsis patients at 28 days. In this trial important value factors for the assessment of costs and outcomes of severe sepsis were also considered. The purpose of the present study is to determine the economic burden of the treatment with Drotrecogin alfa, according to a cost-effectiveness analysis based on the data of the PROWESS trial. The study has been adapted to the italian health environment. As regards to the costs per surviving patient and costs per QALY (Quality Adjusted Life Year, the predicted cost-effectiveness ratio of drotrecogin alfa in severe sepsis patients is much lower than the standard values considered as acceptable in the international litterature.

All patients were retreated with PEG-IFN 2a or 2b per week, associated with RBV, through oral route, with doses determined according to weight (1,000 mg if weight ≤ 75 Kg and 1,250 mg if ≥ 75 Kg per day for 48 weeks. The HCV-RNA was tested by Polymerase Chain Reaction (PCR. Virological Response (VR within 48 weeks and SVR in the 72 weeks was considered for evaluation of treatment efficacy. Analyses were performed in patients who received at least one dose of PEG-IFN. Results The SVR rate for non-responders to previous treatment was 34.4% and for relapsers was 50% (p = 0.031. As predictive factors that contribute to improve SVR, were identified the age (p = 0.005, to be relapsers to previous treatment (p = 0.023 and present liver biopsy examination Metavir F0-F2 (p = 0.004. In assessing the safety profile, 51 patients (23.6% discontinued treatment prematurely. Conclusions This alternative retreatment for patients who have failed prior therapies for anti-HCV, has demonstrated promising SVR rate, provided that it includes a careful selection of patients with predictors of response and adverse events monitored.

    Full Text Available Introdução: Talassemia alfa é uma síndrome associada à redução da síntese de cadeias de globina do tipo alfa. A gravidade das manifestações clínicas está relacionada com a quantidade de globinas produzida e a estabilidade das cadeias beta presentes em excesso. A talassemia alfa mínima resulta da deleção de apenas um dos quatro genes a (-α/αα. Clinicamente apresenta anemia leve com microcitose ou ausência de anemia, sendo o diagnóstico realizado por meio de visualização da hemoglobina (Hb H por eletroforese alcalina em acetato de celulose ou por identificação de inclusões celulares de Hb H coradas pelo azul de crezil brilhante. Objetivo: Avaliar portadores de talassemia alfa e seus respectivos progenitores, correlacionando perfil hematológico e presença de Hb H, utilizando procedimentos laboratoriais clássicos em três diferentes amostragens. Discussão e conclusão: Os dados obtidos mostram que a presença de Hb H, indicativo de talassemia alfa, pode não ser confirmada em uma análise posterior. Entre os fatores que podem influenciar no não aparecimento de Hb H em pessoa comprovadamente com talassemia alfa está a deficiência de ferro. A talassemia alfa está associada a defeitos envolvendo os genes codificadores da cadeia alfa, mas também pode estar relacionada com desbalanciamento temporário na expressão dos genes globina, diminuição de alfa ou aumento de beta, o que poderia explicar o aparecimento de tetrâmeros de cadeia beta (Hb H, sugerindo diagnóstico de talassemia alfa mínima.Introduction: Alpha thalassemia is a syndrome with associated with the reduction of alpha globin chain synthesis.

    Chemical reactivity descriptors within the conceptual density functional theory can be used to understand the nature of the interactions between two monomers of the Group 2B metal halides. This information might be valuable in the development of adequate force law parameters for simulations in the liquid state. In this study, MX2 monomers and dimers, where M = Zn, Cd, Hg and X = F, Cl, Br, I, were investigated in terms of chemical reactivity descriptors. Relativistic effects were taken into account using the effective core potential (ECP) approach. Correlations were produced between global and local reactivity descriptors and dimerization energies. Results presented in this work represent the first systematic investigation of Group 2B metal halides in the literature from a combined point of view of both relativistic effects and chemical reactivity descriptors. Steric effects were found to be responsible for the deviation from the chemical reactivity principles. They were introduced into the chemical reactivity descriptors such as local softness.

    The potential of agent-based systems has not been realized yet, in part, because of the lack of understanding of how the agent technology supports industrial needs and emerging standards. The area of business-to-business electronic commerce (b2b e-commerce) is one of the most rapidly developing sectors of industry with huge impact on manufacturing practices. In this paper, we investigate the current state of agent technology and the feasibility of applying agent-based computing to b2b e-commerce in the circuit board manufacturing sector. We identify critical tasks and opportunities in the b2b e-commerce area where agent-based services can best be deployed. We describe an implemented agent-based prototype system to facilitate the bidding process for printed circuit board manufacturing and assembly. These activities are taking place within the Internet Commerce for Manufacturing (ICM) project, the NIST- sponsored project working with industry to create an environment where small manufacturers of mechanical and electronic components may participate competitively in virtual enterprises that manufacture printed circuit assemblies.

    LUCID is a gas Cerenkov detector deployed near to the beam‐pipe at 17 m either side of the ATLAS Intersection point. The LUCID detector ‐ when calibrated via a Van der Meer scan – is now measuring absolute luminosity on a bunch‐by‐bunch basis. It is now measuring integrated luminosity up to high luminosity with a precision of around 3%. The technical challenges that had to faced to make this measurement as well as upgrade plans for LUCID will be presented. In addition to LUCID, we will discuss that ALFA detector (Absolute Luminosity for ATLAS) and its status as well as the progress on the ATLAS Forward Protons project (AFP) that plans to deploy detectors to tag and measure, with 3‐D silicon detectors, both protons in exclusive central diffractive processes.

    The cutaneous T-cell lymphomas including mycosis fungoides and the Sézary syndrome, are indolent lymphomas with early systemic dissemination. Like the indolent B-cell lymphomas, they cannot be cured by currently available systemic chemotherapy so new systemic therapies need to be developed. A study of very high-dose recombinant interferon alfa-2a was, therefore, initiated in 20 patients with advanced cutaneous T-cell lymphoma (5 in stage II, 2 in stage III and 13 in stage IV). All patients were refractory to at least 2 standard therapies, including topical nitrogen mustard (18 patients), psoralens and ultraviolet A light (12 patients), total skin electron irradiation (14 patients) and systemic chemotherapy (16 patients). Nine out of 20 patients (45%; 95% confidence interval 25-69%) had either objective partial or complete responses within 3 months of starting treatment. Maximal response, however, often did not occur for at least one year. The median duration of response was 5.5 months and all complete responses lasted more than 2 years. Response frequencies were equal at both cutaneous and extracutaneous sites and in patients with or without prior chemotherapy. Toxicity was exhibited primarily as a flu-like syndrome consisting of fever, malaise, fatigue, anorexia and weight loss which necessitated dose reductions in all patients. Transient elevations in liver function and decreases in renal function and granulocyte counts occurred in some patients. It is concluded that interferon alfa-2a is highly active against advanced cutaneous T-cell lymphomas and that it should be studied in its early stages. It should also be evaluated in combination with other biological agents and with chemotherapy.

    de la UE no han sido estrategias eficaces para promover los derechos humanos en la isla. Al ser diferentes, las políticas de la UE y EEUU incluso han contribuido a mantener el régimen castrista en el poder: la UE por su reconocimiento diplomático y la cooperación económica; EEUU, al proporcionar una imagen de enemigo externo. Por ello, y ante el nuevo panorama que ofrece el cambio de gobierno en Cuba, la próxima revisión de la Posición Común de la UE y las elecciones presidenciales en EEUU, es necesario replantearse los objetivos y estrategias políticas para incentivar los derechos humanos en Cuba.

El presente artículo muestra que éste es el caso de los Informes del Desarrollo Humano del Programa de Naciones Unidas para el Desarrollo (PNUD. Mediante un sencillo ejercicio hermenéutico se demuestra que existen fuertes contradicciones entre lo que se expresa explícitamente y lo que subyace implícitamente. El individuo supuestamente libre, clave en el concepto de desarrollo humano, deviene un autómata carente de libertad bajo el imperio de la eficiencia y la racionalidad instrumental. El PNUD, asumiendo acríticamente los fundamentos filosóficos y antropológicos que han dado forma al status quo político-cultural actual, cae en los mismos vicios que supuestamente pretende superar.

El desciframiento del genoma humano, con la consiguiente identificación y localización de los 50.000 a 100.000 genes que configuran su patrimonio genético, permitirá el progresivo esclarecimiento de los mecanismos reguladores de la expresión génica y pondrá al alcance del hombre posibilidades espléndidas, que requerirá años desentrañar. El acelerado ritmo en la caracterización de nuevos genes está desencadenando la posibilidad de pronosticar un número cada vez mayor de enfermedades genéticas y, por tanto, puede propiciar la práctica de una Medicina preventiva cada vez más rigurosa. Sin embargo, las posibles aplicaciones del conocimiento científico que aporta este proyecto suscitan también importantes inquietudes, desde el momento en que cada ser humano puede convertirse en un ser sin intimidad biológica. Por otra parte, la tecnología del ADN recombinante, al tiempo que aporta la enorme posibilidad de una futura terapia génica, suscita también legítimas preocupaciones sobre el correcto uso de estos conocimientos. En este artículo se abordan algunas de las cuestiones de carácter ético que ya plantea actualmente el Proyecto del Genoma Humano. Se adopta la perspectiva según la cual el respeto al patrimonio genético debería estar siempre presidido por un principio básico: no perder nunca de vista al hombre, esto es, al ser humano y su derecho a la identidad personal propia.

The conclusion is that human rights are foreign to Confucianism and, by extension, to the Chinese culture. Ultimately, however, human rights are not necessarily incompatible with that perspective.

    The Mediator multiprotein complex physically links transcription factors to RNA polymerase II and the basal transcription machinery. While the Mediator complex has been shown to be required for transcriptional initiation and elongation, the understanding of its interplay with histone modifying enzymes and post‐translational modifications remains elusive. In this issue of The EMBO Journal, Yao et al (2015) report that the MED23 subunit of the Mediator complex physically associates with the heterodimeric RNF20/40 E3‐ligase complex to facilitate the monoubiquitylation of histone H2B on gene bodies of actively transcribed genes.

    Full Text Available Applied Ethics usually refers to human beings, to their practical problems and to their interests. However, the sphere of ethical issues has expanded during the last years. In spite of the fact that the moral point of view is still grounded on anthropocentrism, the environment and living beings are now the aim object of some moral concern. Justice, as a moral principle, could expand itself, as well, in order to include nonhuman beings: their interest and their welfare. Prom a moderate anthropocentric standpoint, this article defends an asymmetrical moral concern. Indeed, we could understand animal' s rights only as a result of human duties towards the own species. This essay claims for direct duties to future generations of humans, and for indirect duties to nonhUman. Therefore, justice between species would enlarge justice between generations.

    La Ética aplicada se suele referir a los problemas prácticos e intereses de los seres humanos. Sin embargo, las cuestiones éticas se han ido ampliando en los últimos años. A pesar de que el punto de vista moral sigue anclado en un enfoque antropocéntrico, el medio ambiente y los seres vivos son ahora objeto de alguna consideración moral. La justicia, como principio moral, puede ampliarse también hasta incluir a los no humanos, sus intereses y su bienestar. Desde un enfoque antropocéntrico moderado, el artículo defiende en este tema una consideración moral asimétrica; pues sólo podemos entender los derechos de los animales como resultado de los deberes de los humanos hacia la propia especie. Son deberes directos hacia las generaciones futuras de humanos, deberes indirectos hacia los no humanos. Por tanto, la justicia entre especies amplía la idea de justicia entre generaciones.

    2010-05-01

    Full Text Available Scenarios has become a popular technique for requirements elicitation and specification building. Since scenarios capture only partial descriptions of the system behavior, an approach for scenario composition and/or integration is needed to produce more complete specifications. The Unified Modeling Language (UML, which has become a standard notation for object-oriented modeling, provides a suitable framework for scenario acquisition using Use Case diagrams and Sequence or Collaboration diagrams. In this paper, we suggest an algorithmic and tool support for composing and integrating scenarios that are represented in form of sequence diagrams. We suggest four operators (;: sequential operator, ||: concurrent operator, ?: conditional operator and  * :iteration operator to compose a set of scenarios that describe a use case of a given system. In this paper, we suggest also to apply the scenario approach to B2B systems (Business to Business. We propose to develop B2B systems as a three activities process deriving formal specifications and code skeletons from UML scenarios. Activities of this proposed process are generally automatic and are supported by a set of developed algorithms and tools.

After a sandwich immunoreaction, the Fe3O4/Au-HRP-Ab2 captured on the electrode surface produced an amplified electrocatalytic response by reduction of enzymatically oxidized hydroquinone in the presence of hydrogen peroxide. The high content of HRP in the Fe3O4/Au-HRP-Ab2 could greatly amplify the electrochemical signal. Under optimal conditions, the reduction current increased with increasing alfa-fetoprotein concentration in the sample, and exhibited a dynamic range of 0.005–10 ng/mL with a detection limit of 3 pg/mL.Conclusion: The amplified immunoassay developed in this work shows good precision, acceptable stability, and reproducibility, and can be used for detection of alfa-fetoprotein in real samples, so provides a potential alternative tool for detection of protein in the laboratory. Furthermore, this immunosensor could be regenerated by simply using an external magnetic field.Keywords: Fe3O4/Au nanoparticles, alfa-fetoprotein, sandwich immunoassay, electrochemical immunosensor

  5. Encephalomyocarditis virus viroporin 2B activates NLRP3 inflammasome.

    Directory of Open Access Journals (Sweden)

    Minako Ito

    Full Text Available Nod-like receptors (NLRs comprise a large family of intracellular pattern- recognition receptors. Members of the NLR family assemble into large multiprotein complexes, termed the inflammasomes. The NLR family, pyrin domain-containing 3 (NLRP3 is triggered by a diverse set of molecules and signals, and forms the NLRP3 inflammasome. Recent studies have indicated that both DNA and RNA viruses stimulate the NLRP3 inflammasome, leading to the secretion of interleukin 1 beta (IL-1β and IL-18 following the activation of caspase-1. We previously demonstrated that the proton-selective ion channel M2 protein of influenza virus activates the NLRP3 inflammasome. However, the precise mechanism by which NLRP3 recognizes viral infections remains to be defined. Here, we demonstrate that encephalomyocarditis virus (EMCV, a positive strand RNA virus of the family Picornaviridae, activates the NLRP3 inflammasome in mouse dendritic cells and macrophages. Although transfection with RNA from EMCV virions or EMCV-infected cells induced robust expression of type I interferons in macrophages, it failed to stimulate secretion of IL-1β. Instead, the EMCV viroporin 2B was sufficient to cause inflammasome activation in lipopolysaccharide-primed macrophages. While cells untransfected or transfected with the gene encoding the EMCV non-structural protein 2A or 2C expressed NLRP3 uniformly throughout the cytoplasm, NLRP3 was redistributed to the perinuclear space in cells transfected with the gene encoding the EMCV 2B or influenza virus M2 protein. 2B proteins of other picornaviruses, poliovirus and enterovirus 71, also caused the NLRP3 redistribution. Elevation of the intracellular Ca(2+ level, but not mitochondrial reactive oxygen species and lysosomal cathepsin B, was important in EMCV-induced NLRP3 inflammasome activation. Chelation of extracellular Ca(2+ did not reduce virus-induced IL-1β secretion. These results indicate that EMCV activates the NLRP3 inflammasome by

  8. Detection of DNA-recombinant human epoetin-alfa as a pharmacological ergogenic aid.

    2002-01-01

    The use of DNA-recombinant human epoetin-alfa (rhEPO) as a pharmacological ergogenic aid for the enhancement of aerobic performance is estimated to be practised by at least 3 to 7% of elite endurance sport athletes. rhEPO is synthesised from Chinese hamster ovary cells, and is nearly identical biochemically and immunologically to endogenous epoetin-alfa (EPO). In a clinical setting, rhEPO is used to stimulate erythrocyte production in patients with end-stage renal disease and anaemia. A limited number of human studies have suggested that rhEPO provides a significant erythropoietic and ergogenic benefit in trained individuals as evidenced by increments in haemoglobin, haematocrit, maximal oxygen uptake (VO2max) and exercise endurance time. The purpose of this review is to summarise the various technologies and methodologies currently available for the detection of illicit use of rhEPO in athletes. The International Olympic Committee (IOC) banned the use of rhEPO as an ergogenic aid in 1990. Since then a number of methods have been proposed as potential techniques for detecting the illegal use of rhEPO. Most of these techniques use indirect markers to detect rhEPO in blood samples. These indirect markers include macrocytic hypochromatic erythrocytes and serum soluble transferrin receptor (sTfr) concentration. Another indirect technique uses a combination of 5 markers of enhanced erythropoiesis (haematocrit, reticulocyte haematocrit, percentage of macrocytic red blood cells, serum EPO, sTfr) to detect rhEPO. The electrophoretic mobility technique provides a direct measurement of urine and serum levels of rhEPO, and is based on the principle that the rhEPO molecule is less negatively charged versus the endogenous EPO molecule. Isoelectric patterning/focusing has emerged recently as a potential method for the direct analysis of rhEPO in urine. Among these various methodologies, the indirect technique that utilises multiple markers of enhanced erythropoiesis appears to

    Full Text Available Loraine Derbyshire, Colin W Thain School of Health, University of Central Lancashire, Preston, United Kingdom Abstract: Chemotherapy induced anemia (CIA is a frequent complication of anticancer treatment, but often remains untreated. The main presenting symptom of CIA is fatigue, and this can have profound implications upon chemotherapy treatment compliance and patients' quality of life (QoL. Nevertheless, a tendency has been seen in both patients and physicians to underestimate the consequences of fatigue. As nurses are taking on greater responsibilities for identifying, monitoring, and in some cases even treating CIA, it is important that they have a clear understanding of the treatment options at their disposal. Erythropoiesis stimulating agents (ESAs have been available as a tool for the treatment of CIA for many years. However, the vast majority of literature on this topic has been targeted towards physicians. Hence, the purpose of this review is to summarize the key ESA studies, with an emphasis on material that is of interest to the nursing community. Herein we present a brief chronological review of the development of ESAs to illustrate how the currently available treatment options for anemia arose. For conciseness, darbepoetin alfa (DA has been used as a model to represent all ESAs; however, important findings from studies of other ESAs have also been included for completeness. We also discuss the management of CIA, based on the available literature and our experience of routine clinical practice in the UK. In conclusion, CIA is important in the context of maintaining QoL in patients undergoing chemotherapy and its effective management needs to be considered as part of their holistic care. Available studies show that ESA treatment can decrease fatigue levels and reduce the need for transfusions. ESAs, such as DA, may therefore be an important treatment option for patients with CIA. DA is well tolerated when used according to current

    Clinical phenotyping is an emerging research information systems capability. Research uses of electronic health record (EHR) data may require the ability to identify clinical co-morbidities and complications. Such phenotypes may not be represented directly as discrete data elements, but rather as frequency, sequential and temporal patterns in billing and clinical data. These patterns' complexity suggests the need for a robust yet flexible extract, transform and load (ETL) process that can compute them. This capability should be accessible to investigators with limited ability to engage an IT department in data management. We have developed such a system, Eureka! Clinical Analytics. It extracts data from an Excel spreadsheet, computes a broad set of phenotypes of common interest, and loads both raw and computed data into an i2b2 project. A web-based user interface allows executing and monitoring ETL processes. Eureka! is deployed at our institution and is available for deployment in the cloud. PMID:24303265

    2002-05-01

    We have performed extensive small-angle neutron scattering (SANS) diffraction studies of the vortex lattice in single crystal YNi2B2C for $B||c$. High-resolution SANS, combined with a field-oscillation vortex lattice preparation technique, allows us to separate Bragg scattered intensities from two orthogonal domains and accurately determine the unit cell angle, . The data suggest that upon increasing field there is a finite transition width where both low- and high-field distorted hexagonal vortex lattice phases, mutually rotated by 45°, coexist. The smooth variation of diffracted intensity from each phase through the transition corresponds to a redistribution of populations between the two types of domains.

    The objective of this investigation is to study the subsonic flow over a missile. In this paper, a model of TOW 2B missile is studied. Two computational approaches are being explored, namely solutions based on the Reynolds-averaged compressible Navier-Stokes equations and solutions based on the inviscid flow (small disturbance theory). The simulations are performed at the Mach number of 0.6, 0.7, 0.8, 0.9 and 1.0 at four angles of attack of 2, 4, 6 and 8 degree. Results obtained from analytical simulation are compared with numerical data. It is found that lift and drag coefficients would go up by increasing of the angle of attack and the Mach number. Trend of changes of the results that obtained from the small disturbance theory is roughly as same as the numeric solution.

    2013-02-01

    Full Text Available Relationship marketing has become extremely important recently due to the fierce competition in today's marketplace. Companies are required to build long-term profitable relationship with customers and to achieve customer loyalty. Also, switching behaviors frequently occur among most of targeted customers. Fewer studies, however, discuss the effects of relationship quality efforts on customer loyalty. Therefore, this study is aimed to investigate the impact of relationship quality on customer loyalty in B2B context in the Egyptian shipping services sector. Building on prior research, we propose relationship quality as a higher construct comprising trust, commitment and satisfaction. An analytical model is developed as a guideline to test the relationships between relationship quality dimensions and customer loyalty.

Much commercial information is exchanged on the internet, especially using the e-marketplaces. The demand and supply matching process becomes complex and difficult on last twenty years since the e-marketplaces play an important role in business management. Companies can achieve significant cost reduction by using e-marketplaces in their trade activities and by using matchmaking systems on finding the corresponding supply for their demand and vice versa. In the literature were proposed many approaches for matchmaking. In this paper we present a conceptual framework of matchmaking in B2B e-marketplaces environment.

    The crystal structure of human nucleosome containing the testis-specific TSH2B variant has been determined. The TSH2B Ser85 residue does not interact with H4 in the nucleosome, and induces a local structural difference between TSH2B and H2B in nucleosomes. The human histone H2B variant TSH2B is highly expressed in testis and may function in the chromatin transition during spermatogenesis. In the present study, the crystal structure of the human testis-specific nucleosome containing TSH2B was determined at 2.8 Å resolution. A local structural difference between TSH2B and canonical H2B in nucleosomes was detected around the TSH2B-specific amino-acid residue Ser85. The TSH2B Ser85 residue does not interact with H4 in the nucleosome, but in the canonical nucleosome the H2B Asn84 residue (corresponding to the TSH2B Ser85 residue) forms water-mediated hydrogen bonds with the H4 Arg78 residue. In contrast, the other TSH2B-specific amino-acid residues did not induce any significant local structural changes in the TSH2B nucleosome. These findings may provide important information for understanding how testis-specific histone variants form nucleosomes during spermatogenesis.

Bajo esa óptica, y ya en particular acerca del escenario jurídico argentino (aunque con varias referencias al derecho comparado, analiza la evolución jurisprudencial y normativa de distintos aspectos que la interacción del derecho internacional de los derechos humanos y el derecho doméstico generan: la ubicación jerárquica de los instrumentos internacionales sobre la materia en el contexto nacional, la cotización jurídica interna que la Corte Suprema de Justicia asigna a los pronunciamientos de la Comisión y la Corte Interamericanas de Derechos Humanos, y la siempre sensible problemática de la ejecución en sede doméstica de las sentencias de dicho tribunal interamericano; temas, todos, que forman parte de los retos más trascendentes a los que se enfrenta cualquier propósito verdadero de consolidación del Estado Constitucional de Derecho sustentado axiológicamente en el respeto cabal de la democracia y los derechos fundamentales.

    Full Text Available La Red de Defensorías de Niñas, Niños y Adolescentes del Gobierno de la Ciudad de Buenos Aires (DNNYA tiene por objetivo declarado la difusión, promoción y defensa de los derechos que han surgido de la Convención Internacional de los Derechos del Niño (CIDN. Se propone, además, como un espacio que ofrece un modo alternativo de resolución de conflictos que no tienen que pasar necesariamente por la justicia. Este objetivo está estrechamente vinculado con la idea de que la tutela del Estado viola sistemáticamente los derechos de los jóvenes y que, por consiguiente, solo debe acudirse a ella cuando todos los mecanismos por los que pudieran proteger se sus derechos, han sido agotados. En tanto la CIDN constituye una especificación de los Derechos Humanos para las particulares circunstancias de vida de la infancia y la adolescencia, el presente trabajo tiene por objeto, en primer término, reflexionar acerca de la posibilidad de considerar a los Derechos Humanos como un catalogo de valores de carácter universal. En segundo lugar, a la luz de los resultados arrojados por mi trabajo de tesis, me propongo analizar las contradicciones que supone la articulación entre lo político y lo económico y la aplicación de políticas de Derechos Humanos en un organismo del Estado.

  8. Development of solar energy education IASEE-Argentina, Arquisur and Alfa-built

    International Nuclear Information System (INIS)

    Three educational experiences are presented in this paper on the development of national and regional networks to incorporate renewable energy in curricular programmes. IASEE-Argentina, established in 1990 as the National Section of IASEE, the International Association for Solar Energy Education, was designated in 1993 as the Education Working Group of ASADES, the Argentine Association of Solar Energy. It holds annual meetings to coincide with the ASADES conference. Arquisur is a regional network established by Architectural Faculties of State Universities within the Mercosur Region, covering Argentina, southern Brazil, Paraguay and Uruguay, to promote exchange and development between the 19 faculties involved. A Working Group set up by Arquisur with members from four countries developed the programme for short post-graduate courses on bioclimatic design and rational energy use in buildings, which has been given in Argentina and Uruguay. Alfa-Built, a project supported by the European Union for promoting academic exchange in the field of energy efficient building is also introduced. This paper presents the development and initial results of these educational experiences. (author)

    Cholangiolocellular carcinoma (CoCC) is a rare malignant liver tumor derived from hepatic progenitor cells, which exist in the canals of Hering. We encountered a case of CoCC with an extremely poor clinical course, initially showing abnormally elevated serum alfa-fetoprotein (AFP). A 72-year-old male presented with a liver tumor and abnormally elevated serum AFP levels (16,399 ng/ml). We preoperatively diagnosed hepatocellular carcinoma and performed extended right hepatectomy, after which the serum AFP levels remarkably decreased to 97 ng/ml. Postoperatively, the disease was pathologically diagnosed as CoCC. Furthermore, immunohistochemical pathological findings were alcian blue negative, cytokeratin (CK) 7 partially positive, CK19 positive, hepatocyte paraffin-1 negative, membranous negative for epithelial membrane antigen, and AFP negative. Fifty-five days later, intra- and extrahepatic recurrence developed, and the patient died 65 days after surgery. Although CoCCs show favorable outcomes, these characteristics of our case were not previously reported. It is necessary to accumulate more information on CoCC. PMID:27363839

    The Pulsar Arecibo L-band Feed Array (PALFA) Survey uses the ALFA 7-beam receiver to search both inner and outer Galactic sectors visible from Arecibo ($32^{\\circ}\\lesssim \\ell \\lesssim 77^{\\circ}$ and $168^{\\circ}\\lesssim \\ell \\lesssim 214^{\\circ}$) close to the Galactic plane ($|b|\\lesssim5^{\\circ}$) for pulsars. In this paper we detail a precursor survey of this region with PALFA, which observed a subset of the full region (slightly more restrictive in $\\ell$ and $|b|\\lesssim1^{\\circ}$) and detected 45 pulsars. For both Galactic millisecond and normal pulsar populations, we compare the survey's detections with simulations to model these populations and, in particular, to estimate the number of observable pulsars in the Galaxy. We place 95\\% confidence intervals of 82,000 to 143,000 on the number of detectable normal pulsars and 9,000 to 100,000 on the number of detectable millisecond pulsars in the Galactic disk. These are consistent with previous estimates. Given the most likely population size in each ca...

    Full Text Available Ilka Schneider, Stephan Zierz Department of Neurology, Martin Luther University Halle-Wittenberg, Halle (Saale, Germany Abstract: Pompe disease, also referred to as glycogenosis type II, is a rare, autosomal recessive disorder that results from the deficiency of the glycogen-degrading enzyme acid α-glucosidase. The classical form presents shortly after birth with muscle hypotonia, cardiac, and respiratory failure resulting in a fatal outcome. The late onset of Pompe disease has a very variable onset and disease presentation that often causes a delayed diagnosis. Until now enzyme replacement therapy with alglucosidase alfa is the only causative therapy option for Pompe patients that can slow down disease progression. However, uncertainty remains about the efficacy regarding survival and quality of life in Pompe patients under this very cost-intensive treatment. This paper provides a systematic review of the literature stressing different aspects of enzyme replacement therapy in infantile and late onset Pompe patients.

    Full Text Available Michael BeckChildren’s Hospital, University of Mainz, Mainz, GermanyAbstract: Pompe disease is a lysosomal storage disorder characterized by muscle weakness and cardiomyopathy. It shows a broad variability regarding the clinical severity as well as the age of onset. In the past, two different recombinant enzyme preparations have been developed for the treatment of Pompe patients: α-glucosidase, produced in rabbit milk, and α-glucosidase, produced in Chinese hamster ovary (CHO cell lines. The CHO enzyme received marketing approval in 2006 after it was proven to be effective in ameliorating muscle strength and improving heart function. The other has not been approved. The clinical efficacy of this enzyme preparation could be confirmed by several clinical trials in patients with different age of onset and disease severity. Enzyme replacement therapy, however, has its limitations due to unsatisfactory access of recombinant α-glucosidase to the muscle cells and due to the formation of antibodies. To overcome these therapeutic restraints, the development of a more effective enzyme preparation may become necessary.Keywords: alglucosidase alfa, alpha glucosidase, Pompe disease, enzyme replacement therapy, glycogen storage disorder type II, acid maltase deficiency

  13. LHC Report: special run with de-squeezed beams for ATLAS/ALFA and TOTEM

    CERN Multimedia

    Helmut Burkhardt for the LHC team

    2015-01-01

    The main high-luminosity proton-proton run of the LHC is complemented by one week per year of special proton-proton runs. The special runs are performed with larger beam sizes at the interaction points to allow the forward physics experiments, TOTEM and ATLAS/ALFA, the chance to make precise measurements of protons as they emerge from collisions at small angles.   In standard high-luminosity operation, the beams are squeezed to give small beam sizes at the interaction points to maximise the collision rates. The “squeeze” takes place at top energy and the beam size at the centre of ATLAS (IP1) and CMS (IP5) is reduced from 66 micrometres at the top of the ramp to 18 micrometres before colliding beams are established. Protons that avoid the fate of an inelastic collision but yet still interact – in elastic or diffractive events – are scattered and emerge in the forward direction. The reduction in beam size has a side effect of increasing the an...

    We present the third installment of HI sources extracted from the Arecibo Legacy Fast ALFA extragalactic survey. This dataset continues the work of the Virgo ALFALFA catalog. The catalogs and spectra published here consist of data obtained during the 2005 and 2006 observing sessions of the survey. The catalog consists of 578 HI detections within the range 11h 36m 6.5; (b) high velocity clouds in the Milky Way or its periphery; and (c) signals of lower S/N which coincide spatially with an optical object and known redshift. 75% of the sources are newly published HI detections. Of particular note is a complex of HI clouds projected between M87 and M49 that do not coincide with any optical counterparts. Candidate objects without optical counterparts are few. The median redshift for this sample is 6500 km/s and the cz distribution exhibits the local large scale structure consisting of Virgo and the background void and the A1367-Coma supercluster regime at cz_sun ~7000 km/s.

According to the Coase paradigm, we would thus expect a deverticalization of the industry and broader scope for anonymous market mechanisms. In reality, such expectations are not fully borne out by the facts. When the industrial structure is concentrated the B2Bgenerally loses its independence, and is owned by the firms which most contribute to its development, e.g. the ones able to bring the liquidity to it. The B2B governance mechanism established by these firms gives hierarchical mechanisms a role which they do not usually play in extensive, anonymous markets.         JEL Codes: D23, L86Keywords: Cost, Transaction Costs, Transactions

    The Src homology 2B(SH2B)family members(SH2B1,SH2B2 and SH2B3)are adaptor signaling proteins containing characteristic SH2 and PH domains.SH2B1(also called SH2-B and PSM)and SH2B2(also called APS)are able to form homo-or hetero-dimers via their N-terminal dimerization domains.Their C-terminal SH2 domains bind to tyrosyl phosphorylated proteins,including Janus kinase 2(JAK2),TrkA,insulin receptors,insulin-like growth factor-1 receptors,insulin receptor substrate-1(IRS1),and IRS2.SH2B1 enhances leptin signaling by both stimulating JAK2 activity and assembling a JAK2/IRS1/2 signaling complex.SH2B1 promotes insulin signaling by both enhancing insulin receptor catalytic activity and protecting against dephosphorylation of IRS proteins.Accordingly,genetic deletion of SH2B1 results in severe leptin resistance,insulin resistance,hyperphagia,obesity,and type 2 diabetes in mice.Neuronspecific overexpression of SH2B1βtransgenes protects against diet-induced obesity and insulin resistance.SH2B1 in pancreaticβcells promotesβcell expansion and insulin secretion to counteract insulin resistance in obesity.Moreover,numerous SH2B1 mutations are genetically linked to leptin resistance,insulin resistance,obesity,and type 2 diabetes in humans.Unlike SH2B1,SH2B2 and SH2B3 are not required for the maintenance of normal energy and glucose homeostasis.The metabolic function of the SH2B family is conserved from insects to humans.

    International Nuclear Information System (INIS)

    The rare earth borates RE2B8O15 (RE = La, Pr, Nd) were synthesized in a Walker-type multianvil apparatus under conditions of 5.5 GPa and 1100 C. Starting from the corresponding rare earth oxides and boron oxide, the syntheses yielded crystalline products of all new compounds that allowed crystal structure analyses based on single-crystal X-ray diffraction data for La2B8O15 and Nd2B8O15. The compound Pr2B8O15 could be characterized via X-ray powder diffractometry. The results show that the new compounds crystallize isotypically to Ce2B8O15 in the monoclinic space group P2/c. The infrared spectra of RE2B8O15 (RE = La, Pr, Nd) have also been studied.

    Full Text Available En este articulo se examinan las relaciones y diferencias entre el concepto de 'capital humano' y el concepto de 'capacidad humana'. El concepto de capital humano es mas limitado puesto que solo concibe las cualidades humanas en su relación con el crecimiento económico mientras que el concepto de capacidades da énfasis a la expansión de libertad humana para vivir el tipo de vida que la gente considera valedera. Cuando se adopta esa visión mas amplia, el proceso de desarrollo no puede verse simplemente como un incremento del PIB sino como la expansión de la capacidad humana para llevar una vida mas libre y mas digna.In this article the relationships and the differences between the concept of 'human capital' and the concept of 'human capability' are examined.

Whenthis broader vision is adopted, the process of development cannot be seen as simply an increase in the GNP, but rather as the expansion of the human capability to live a more free and worthy life.

    Full Text Available El propósito de este artículo es presentar un marco conceptual a la noción de desarrollo humano como parte importante de una vieja pregunta en ocasiones olvidada, censurada y desde hace un tiempo recuperada por las ciencias sociales; esto es, la pregunta por la buena sociedad. Esta cuestión es algo más que un llamado ético o axiológico. Sus repercusiones son hondas y tienen un contenido social, político, económico y jurídico inevitable. El reto es recuperar una pregunta que va más allá del positivismo tecnocientífico que ha hecho de los datos cuantitativos, del economicismo, de los números y de la falta de crítica una nueva forma de alienación. En este aparente viaje a ninguna parte, no basta con reconocerse como copartícipes del destino de Sísifo, tentados por el carpe diem de Baco o hipnotizados por la vocación de Prometeo y Vulcano.

However, during the last years, the studies of apes have revealed the existence of these adaptive traits in other primates. This fact has seriously damaged the validity of such a materialist - biased approach (only what is left in the archaeological record is liable to be interpreted as a clear-cut human diagnosis. Gradualist and punctuated explanations of the emergence of human behavior are mentioned as theoretical frameworks and the need of focusing such an issue from a socio-ecological consideration is proposed.

    Objective: To study the effects of chronic lithium on N-methyl-d-aspartate receptor subunit 2B (NR2B) tyrosine phosphorylation and the interactions of NR2B and PSD-95 with Src induced by cerebral ischemia/reperfusion (I/R). Methods: Transient (15 min) cerebral ischemia was induced by four-vessel occlusion procedure in SD rats. Immunoprecipitation (IP) and immunoblotting (IB)were performed to investigate the phosphorylation and interactions of proteins. The effects of lithium on tyrosine phosphorylation of NR2B and its interactions with PSD-95 and Src were examined. Results: Transient cerebral ischemia 15 min followed by reperfusion 6 h (I/R 6h) caused a significant increase in tyrosine phosphorylation of NR2B. Administration of LiCl for 7days before ischemia caused a profound decrease in tyrosine phosphorylation of NR2B. Similiarly, the interactions of NR2B and PSD-95 with Src were also enhanced by I/R 6 h.moreover, these interactions were also inhibited by chronic lithium. Conclusion: Pretreatment with lithium decrease tyrosine phosphorylation of NR2B and interactions of NR2B and PSD-95 with Src during cerebral I/R.

    Safety assessment is a tool which, by means of an iterative procedure, allows the evaluation of the performance of a disposal system and its potential impact on human health and the environment. Radionuclides from a deep geological disposal facility may not reach the surface environment until many tens of thousands of years after closure of the facility. The BIOMASS Programme on BIOsphere Modelling and ASSessment developed Examples of 'Reference Biospheres' to illustrate the use of the methodology and to demonstrate how biosphere models can be developed and justified as being fit for purpose. The practical examples are also intended to be useful in their own right. The Example Reference Biosphere 2B presented here involves the consideration of alternative types of geosphere-biosphere interfaces and calculation of doses to members of hypothetical exposure groups arising from a wide range of exposure pathways within agricultural and semi-natural environments, but without allowing for evolution of the corresponding biosphere system. The example presented can be used as a generic analysis in some situations although it was developed around a relatively specific conceptual model. It should be a useful practical example, but the above numerical results are not intended to be understood as prescribed biosphere 'conversion factors'.

    Phonons in a metal interact with conduction electrons which give rise to a finite linewidth. In the normal state, this leads to a Lorentzian shape of the phonon line. Density functional theory is able to predict the phonon linewidths as a function of wave vector for each branch of the phonon dispersion. An experimental verification of such predictions is feasible only for compounds with very strong electron–phonon coupling. YN2B2C was chosen as a test example because it is a conventional superconductor with a fairly high c (15.2 K). Inelastic neutron scattering experiments did largely confirm the theoretical predictions. Moreover, they revealed a strong temperature dependence of the linewidths of some phonons with particularly strong electron–phonon coupling which can as yet only qualitatively be accounted for by theory. For such phonons, marked changes of the phonon frequencies and linewidths were observed from room temperature down to 15 K. Further changes were observed on entering into the superconducting state. These changes can, however, not be described simply by a change of the phonon linewidth.

  10. El alivio del dolor: ¿es un derecho humano?

    2012-06-01

    Full Text Available En este trabajo se analiza el artículo titulado "El alivio del dolor como un derecho humano", escrito por F. Brennan y M. Cousins, en donde los autores proclaman la formulación de un novedoso derecho fundamental y revisan diversos instrumentos internacionales de Derechos Humanos, para sustentar el argumento de que el paciente debe ser protegido contra el insuficiente tratamiento del dolor. Diversos autores y organizaciones han denunciado las causas, debidas a diversos factores, por las cuales el dolor no es tratado en toda su extensión. Los factores normativos estriban en la autorización y/o prohibición de la distribución, consumo, uso y comercialización de fármacos, por parte de las agencias gubernamentales. Los factores económicos son multicausales puesto que se relacionan directamente con el acceso a servicios de salud y a medicamentos. Se identifica como un serio problema de salud pública, el que no se destinen suficientes recursos para la implementación de unidades para tratamiento del dolor crónico o temporal o para la investigación relativa al tema. La falta de educación y actualización de los profesionales de salud es otro problema importante. Dentro de las causas sociales se encuentran entre otras, la desigualdad en el acceso a los servicios de salud, la pobreza, la falta de cobertura médica y la discriminación hacia ciertos grupos sociales. En el texto se hace un sucinto recorrido por los principales instrumentos internacionales de Derechos Humanos. Se retoman los instrumentos examinados por Brennan y Cousins, con la aportación de agregar documentos regionales del Sistema Interamericano de Derechos Humanos. Para los Estados Miembros de la Organización de los Estados Americanos (OEA, que padecen la problemática propia de los países en vías de desarrollo: muchas necesidades, alta densidad de población y escasez de recursos, se torna urgente plantearse el Derecho a la Salud bajo nuevas perspectivas.

Partimos del análisis del contenido de este derecho, para después analizar su reconocimiento en los diferentes instrumentos internacionales especialmente en la Declaración Universal de los Derechos Humanos. Este fundamento permitirá abordar el tema en el contexto de las diferentes Constituciones que ha tenido el Ecuador desde que se fundó como república en 1830 hasta llegar a la actual Constitución de la República del Ecuador del 2008. La libertad de religión en el constitucionalismo ecuatoriano ha venido poco a poco evolucionando a lo largo de la historia desde la imposición de una sola religión por parte del Estado en épocas conservadoras, pasando después a un liberalismo laico donde inclusive se prohibía toda práctica religiosa, hasta llegar a épocas modernas en donde se establece la libertad de religión como un derecho propiamente dicho en el que se garantiza a las personas la libertad de profesar la religión de su elección. Palavras- chave: Derechos humanos, liberdad de religión, reconocimiento del derecho a la liberdad de religión, derecho a la liberdad de religión en el constitucionalismo ecuatoriano. HUMAN RIGHT TO FREEDOM OF RELIGION ABSTRACT In this article we analyze the recognition of the human right to freedom of religion in international instruments of human rights and their influence on Ecuadorian constitutionalism. We start by analyzing the content of this right. Next we analyze the recognition of this right in various international instruments especially the Universal Declaration of Human Rights. This information allows us to then address the issue in the context of the various Constitutions which Ecuador has had since its foundation as a republic in 1830 through the present Constitution

    Metastable equilibrium solubilities and such physico-chemical properties as densities, conductivity, pH, refractive index and viscosity of the solution for the quaternary system Li2B4O7+Na2B4O7+K2B4O7+H2O at 15℃ were determined experimentally. According to the experimental data, the metastable equilibrium phase diagram was plotted. In the metastable phase diagram, there are one invariant point, three univariant curves, and three fields of crystallization: Li2B2O4·16H2O, Na2B4O7·10H2O, and K2B4O7·4H2O. Potassium borate (K2B4O7·4H2O) has the smallest crystallization field and sodium borate (borax) has the biggest one. Also, the relationship diagram between the properties and the ion concentration of solution was constructed. It can be seen from the relationship diagram that the metastable equilibrium solution density values, viscosity values and refractive index values are increased apparently with the rise of lithium borate concentration, reaching the maximum values at invariant point F. Electrical conductivity values and pH values, however, fall down with the rise of ion concentration on the whole.

  18. Beyond the exchange--the future of B2B.

    Wise, R; Morrison, D

    2000-01-01

    Using the Internet to facilitate business-to-business commerce promises many benefits, such as dramatic cost reductions and greater access to buyers and sellers. Yet little is known about how B2B e-commerce will evolve. The authors argue that changes in the financial services industry over the past two decades provide important clues. Exchanges, they say, are not the primary source of value in information-intensive markets; value tends to accumulate among a diverse group of specialists that focus on such tasks as packaging, standard setting, arbitrage, and information management. Because scale and liquidity are vitally important to efficient trading, today's exchanges will consolidate into a relatively small set of mega-exchanges. Originators will handle the origination and aggregation of complex transactions before sending them on to mega-exchanges for execution. E-speculators, seeking to capitalize on an abundance of market information, will tend to concentrate where relatively standardized products can be transferred easily among a large group of buyers. In many markets, a handful of independent solution providers with well-known brand names and solid reputations will thrive alongside mega-exchanges. Sell-side asset exchanges will create the networks and provide the tools to allow suppliers to trade orders among themselves, sometimes after initial transactions with customers are made on the mega-exchanges. For many companies, traditional skills in such areas as product development, manufacturing, and marketing may become relatively less important, while the ability to understand and capitalize on market dynamics may become considerably more important.

    The wave power converter consists of a float 2.5 meter in diameter, connected by a rope to a seabed-mounted piston pump, installed on 25 meter deep water 2,5 km offshore Hanstholm, Denmark. The converter is designed to absorb an average maximum power of 1 kW. Measured data in real sea conditions are compared to results based on computer simulations and previous tank testing. Losses caused by rope elasticity and hysteresis, friction in the pump and back flow through the valves are assessed. The economic perspectives of a large wave power plant are presented, based on a revised prototype incorporating the results and experience gained during the test period. The wave energy conversion test `Hanstholm phase 2B` has showed, that it it technically possible to exploit the offshore wave energy resource. This source of energy could become attractive for commercial enterprise. The wave power converter demonstrated a reliable performance over a period of nine months. It produced energy under all wave conditions and survived storm waves of 9,6 m. A 300 MW wave power plant in the Danish part of the North sea is estimated to produce electricity at a cost between 2,1 - 2,4 DKK/kWh. The electrical transmission to shore contribute to approximately 20% of the cost. New data predict a potential of 23 kW per meter wave front. The energy plan Energy 21 proposed by the Danish Department of Energy, includes a scenario incorporating wave energy in the energy system year 2030. A strategy for the development of wave energy, has been proposed as part of the project OWEC-1 supported by the European Joule R and D programme. A proposal for future Danish initiatives to develop second generation point absorber systems is outlined. (ARW) 29 refs.

    Acid sphingomyelinase deficiency (ASMD; Niemann-Pick disease type A and B) is a lysosomal storage disorder characterized by abnormal intracellular sphingomyelin (SM) accumulation. Prominent liver involvement results in hepatomegaly, fibrosis/cirrhosis, abnormal liver chemistries, and a proatherogenic lipid profile. Olipudase alfa (recombinant human ASM) is in clinical development as an investigational enzyme replacement therapy for the non-neurological manifestations of ASMD. In a phase 1b study conducted to evaluate the safety and tolerability of within-patient dose escalation with olipudase alfa, measurement of SM levels in liver biopsies was used as a pharmacodynamic biomarker of substrate burden. Five adult patients with non neuronopathic ASMD received escalating doses of olipudase alfa every 2 weeks for 26 weeks. Liver biopsies obtained at baseline and 26 weeks after treatment were evaluated for SM storage by histomorphometric analysis, biochemistry, and electron microscopy. Biopsies were also assessed for inflammation and fibrosis, and for the association of SM levels with liver volume, liver function tests, and lipid profiles. At baseline, SM storage present in Kupffer cells and hepatocytes ranged from 9.8% to 53.8% of the microscopic field. After 26 weeks of treatment, statistically significant reductions in SM (P<0.0001) measured by morphometry were seen in 4 patients with evaluable liver biopsies. The 26-week biopsy of the fifth patient was insufficient for morphometric quantitation. Posttreatment SM levels ranged from 1.2% to 9.5% of the microscopic field, corresponding to an 84% to 92% relative reduction from baseline. Improvements in liver volume, liver function tests, and lipid profiles were also observed. This study illustrates the utility of SM assessment by liver biopsy as a pharmacodynamic biomarker of disease burden in these patients. PMID:27340749

    We present a study of magnetization measurements performed on the single crystals of YNi2B2C and LuNi2B2C. For both the compounds, we find flux jumps in magnetisation values in the respective field regions, where the structural transitions in the flux line lattice symmetry have been reported in these systems via the small angle neutron scattering experiments. The magnetisation hysteresis loops and the AC susceptibility measurements show pronounced peak effect as well as second magnetisation peak anomaly for both YNi2B2C and LuNi2B2C. Based on these results, a vortex phase diagram has been constructed for YNi2B2C for $H \\Arrowvert c$ depicting different glassy phases of the vortex matter.

    Geometrical optimization and theoretical calculation of the vibrational frequencies have been performed for C2B10H12, NB11H12 and C2B10Cl by using Gaussian 92 program at 6-31G basis set. The results obtained in this work are in agreement with experimental ones. The optimized geometry and vibrational spectra show that the icosahedral configuration remains unchanged upon converting from B12H122- to the title compounds. The vibrational spectrum of C2B10H11Cl features the absence of C-Cl stretching vibration. But the (C2B10H11)-Cl vibration mode in the low frequency region is as the case for two-atom molecules if the group (C2B10H11) is considered as a pseudoatom

    Radio observations of gas in the Milky Way and Local Group are vital for understanding how galaxies function as systems. The unique sensitivity of Arecibo's 305 m dish, coupled with the 7-beam Arecibo L-Band Feed Array (ALFA), provides an unparalleled tool for investigating the full range of interstellar phenomena traced by the H I 21 cm line. The GALFA (Galactic ALFA) H I Survey is mapping the entire Arecibo sky over a velocity range of -700 to +700 km s-1 with 0.2 km s-1 velocity channels and an angular resolution of 3.4'. We present highlights from the TOGS (Turn On GALFA Survey) portion of GALFA-H I, which is covering thousands of square degrees in commensal drift scan observations with the ALFALFA and AGES extragalactic ALFA surveys.

    AIM: The clinical significance of co-infection of SENV-D among patients with chronic hepatitis C (CHC) and response of both viruses to combination therapy with high-dose interferon-alfa (IFN) plus ribavirin remain uncertain and are being investigated.METHODS: Total 164 (97 males and 67 females, the mean age 48.1±11.4 years, range: 20-73 years, 128histologically proved) naive CHC patients were enrolled in this study. SENV-D DNA was tested by PCR method.Detection of serum HCV RNA was performed using a standardized automated qualitative RT-PCR assay (COBAS AMPLICOR HCV Test, version 2.0). HCV genotypes 1a,1b, 2a, 2b, and 3a were determined by using genotypespecific primers. Pretreatment HCV RNA levels were determined by using the branched DNA assay (Quantiplex HCV RNA 3.0). There are 156 patients receiving combination therapy with IFN 6 MU plus ribavirin for 24 wk and the response to therapy is determined.RESULTS: Sixty-one (37.2%) patients were positive for SENV-D DNA and had higher mean age than those who were negative (50.7±10.6 years vs46.6±11.6 years,P = 0.026). The rate of sustained viral response (SVR)for HCV and SENV-D were 67.3% (105/156) and 56.3%(27/48), respectively. By univariate analysis, the higher rate of SVR was significantly related to HCV genotype non-1b (P<0.001), younger ages (P = 0.014), lower pretreatment levels of HCV RNA (P = 0.019) and higher histological activity index (HAI) score for intralobular regeneration and focal necrosis (P = 0.037). By multivariate analyses, HCV genotype non-1b, younger age and lower pretreatment HCV RNA levels were significantly associated with HCV SVR (odds ratio (OR)/95% confidence interval (CI): 12.098/0.02-0.19, 0.936/0.890-0.998, and 3.131/1.080-9.077, respectively). The SVR of SENV-D was higher among patients clearing SENV-D than those who had viremia at the end of therapy (P = 0.04).CONCLUSION: Coexistent SENV-D infection, apparently associated with higher ages, is found in more than onethird Taiwanese

  14. Summary of Session 2.B. Planning and implementation

    International Nuclear Information System (INIS)

    Session 2.B. can be summarized by a statement in one of the papers given in the session: 'Dismantling of nuclear facilities is basically not a technical problem but a challenge to project management and logistics once the legal and economical boundary conditions have been clarified'. The session balanced generic principles and concerns raised by decommissioning projects with practical examples of lessons learned from some specific projects and raised some key issues for all involved in decommissioning - whether regulator, operator or other stakeholder. Ideally, planning for decommissioning should start as early as possible, preferably when the facility is being designed. When a facility or activity is shut down it is very important that a formal decision to decommission is made so that the situation is clear to all stakeholders. The impact on the work force and the local community due to the cessation of operation of a facility must be recognized and addressed early in the transition from operation to decommissioning. Factors such as uncertainty, potential job losses and diminution of career paths as research careers are replaced by construction/deconstruction jobs all lead to poor morale and an exodus of qualified staff. Attention to safety culture during all phases of decommissioning will assist in ensuring that safety and environmental protection objectives are met, as well as promoting desired worker retention. Some issues for future consideration include the following: Consider the role of the State in the clearance process, should the State take responsibility for decommissioned sites that cannot be 'green fielded'?; Consider establishing expert missions focused on decommissioning similar to those of the IAEA's Operational Safety Assessment Review Team and WATRAP. Actions that could be taken include: Clarifying the status of all shutdown facilities that have not declared decommissioning; Ensuring that the focus of the decommissioning programme includes all

    Full Text Available Um ambiente competitivo de negócios é decorrência cada vez maior de uma administração eficaz do capital humano. Estrutura, tecnologia, recursos financeiros e materiais são aspectos meramente físicos e inertes que precisam ser administrados inteligentemente por meio das pessoas que constituem a organização. A Teoria do Capital Humano é uma derivação da Teoria Econômica Neoclássica e, ao mesmo tempo, uma atualização, do axioma liberal do indivíduo livre, soberano e racional. Ressurgiu com a crise do modelo tayloris ta-fordis ta, associada à redefinição das relações de trabalho na empresa e do papel do sistema educacional. A qualidade dos funcionários de uma organização, seus conhecimentos e habilidades, entusiasmo e satisfação com seus cargos, seu senso de iniciativa para gerar riqueza, tudo isso tem forte impacto na produtividade da organização, no nível de serviço ao cliente, na reputação e na competitividade. Para qualquer que seja a área empresarial escolhida, o futuro administrador necessita ter uma visão sobre como lidar com assuntos relacionados com pessoas para alcançar o seu sucesso profissional e levar a sua organização rumo à excelência e à competitividade. Em seu conjunto, as pessoas constituem o capital humano da organização. Esse capital pode valer mais ou valer menos, na medida em que contenha talentos capazes de agregar valor à organização e torná-la mais ágil e competitiva. Portanto, esse capital vale mais na medida em que consiga influenciar as ações e os destinos da organização. A era da informação torna o trabalho menos físico e mais mental, pois as pessoas deixaram de ser fornecedoras de mão-de-obra para serem alçadas à categoria de fornecedoras de conhecimento e de competências. Do mesmo modo que o capital humano é relevante para a sociedade e para as organizações, observa-se que o desenvolvimento econômico também possui um papel de suma importância. Define

    Nonacog alfa is a recombinant factor IX (FIX) product indicated for treatment and prevention of bleeding episodes in patients with haemophilia B. This posthoc analysis evaluated the safety of nonacog alfa in key clinical studies across 15 years. Data were pooled from six prospective studies that utilized on-demand, prophylactic and preventive nonacog alfa regimens: three open-label, nonrandomized studies that assessed efficacy and safety; a bioequivalence study of original and reformulated nonacog alfa; an open-label, randomized study that compared on-demand and prophylactic treatment; and a noninterventional observational registry study that evaluated safety. Safety assessments included adverse events, serious adverse events (SAEs) and events of special interest. In total, 412 patients received nonacog alfa treatment. Adverse events occurred in 220 patients (53.4%), the most common being pyrexia (n = 63), nasopharyngitis (n = 53) and cough (n = 52). Forty-eight patients (11.7%) experienced treatment-related adverse events; the most common were hypersensitivity (n = 6), urticaria (n = 6), FIX inhibition (n = 5) and pyrexia (n = 4). Seventy-four patients (18.0%) developed SAEs. Thirty-seven events of special interest occurred in 31 (7.5%) patients. Events of special interest included allergic-type manifestations (n = 15), inhibitor development (n = 5), lack of effect (n = 8), red blood cell agglutination in tubing or syringe (n = 7), and thrombogenicity (n = 2). Six patients (1.5%) withdrew due to seven adverse events: hypersensitivity (n = 3), drug eruption, pruritic rash, urticaria and decreased therapeutic response (n = 1 each). Four patients died during the study; no deaths were related to study medication. This pooled safety analysis in haemophilia B patients confirmed the safety of nonacog alfa across various patient populations. PMID:26196195

    Full Text Available The Phox2b gene is necessary for the development of the autonomic nervous system, and especially, of respiratory neuronal circuits. In the present study, we examined the role of Phox2b in ventilatory and thermoregulatory responses to hypoxic stress, which are closely related in the postnatal period. Hypoxic stress was generated by strong thermal stimulus, combined or not with reduced inspired O2. To this end, we exposed 6-day-old Phox2b+/- pups and their wild-type littermates (Phox2b+/+ to hypoxia (10% O2 or hypercapnia (8% CO2 under thermoneutral (33°C or cold (26°C conditions. We found that Phox2b+/- pups showed less normoxic ventilation (VE in the cold than Phox2b+/+ pups. Phox2b+/- pups also showed lower oxygen consumption (VO2 in the cold, reflecting reduced thermogenesis and a lower body temperature. Furthermore, while the cold depressed ventilatory responses to hypoxia and hypercapnia in both genotype groups, this effect was less pronounced in Phox2b+/- pups. Finally, because serotonin (5-HT neurons are pivotal to respiratory and thermoregulatory circuits and depend on Phox2b for their differentiation, we studied 5-HT metabolism using high-pressure liquid chromatography, and found that it was altered in Phox2b+/- pups. We conclude that Phox2b haploinsufficiency alters the ability of newborns to cope with metabolic challenges, possibly due to 5-HT signaling impairments.

    Mammalian detoxification processes have been the focus of intense research, but little is known about how wild herbivores process plant secondary compounds, many of which have medicinal value or are drugs. cDNA sequences that code for three enzymes of the cytochrome P450 (CYP) 2B subfamily, here termed 2B35, 2B36, and 2B37 have been recently identified from a wild rodent, the desert woodrat (Malenke et al., 2012). Two variant clones of each enzyme were engineered to increase protein solubility and to facilitate purification, as reported for CYP2B enzymes from multiple species. When expressed in Escherichia coli each of the woodrat proteins gave the characteristic maximum at 450 nm in a reduced carbon monoxide difference spectrum but generally expressed at lower levels than rat CYP2B1. Two enzymes, 2B36 and 2B37, showed dealkylation activity with the model substrates 7-ethoxy-4-(trifluoromethyl)coumarin and 7-benzyloxyresorufin, whereas 2B35 was inactive. Binding of the monoterpene (+)-α-pinene produced a Type I shift in the absorbance spectrum of each enzyme. Mutation of 2B37 at residues 114, 262, or 480, key residues governing ligand interactions with other CYP2B enzymes, did not significantly change expression levels or produce the expected functional changes. In summary, two catalytic and one ligand-binding assay are sufficient to distinguish among CYP2B35, 2B36, and 2B37. Differences in functional profiles between 2B36 and 2B37 are partially explained by changes in substrate recognition site residue 114, but not 480. The results advance our understanding of the mechanisms of detoxification in wild mammalian herbivores and highlight the complexity of this system. - Highlights: • Three CYP2B enzymes from Neotoma lepida were cloned, engineered, and expressed. • A mix of catalytic and binding assays yields unique results for each enzyme. • Mutational analysis indicates CYP{sub 2}B substrate recognition remains to be clarified. • Reported N. lepida gene

    Full Text Available Brain-specific neural-zinc-finger transcription factor-2b (NZF2b/7ZFMyt1 is induced in the mesolimbic dopaminergic region after chronic cocaine exposure and lentiviral-mediated expression of NZF2b/7ZFMyt1 in the nucleus accumbens results in decreased locomotor activity (Chandrasekar and Dreyer, 2009. In this study the role of NZF2b/7ZFMyt1 in active cocaine seeking and of its interaction with histone deacetylase on the altered behavior has been observed. Localized expression of NZF2b/7ZFMyt1 in the nucleus accumbens resulted in attenuated cocaine self-administration, whereas silencing this transcription factor with lentiviruses expressing siRNAs increased the animal′s motivation to self-infuse cocaine. Low doses of sodium butyrate, a potent inhibitor of histone deacetylase, were sufficient to reverse the NZF2b/7ZFMyt1-mediated decrease in cocaine self-administration. NZF2b/7ZFMyt1 expression resulted in strong induction of transcription factors REST1 and NAC1 and of the dopamine D2 receptor, with concomitant inhibition of BDNF and its receptor TrkB. We show that NZF2b/7ZFMyt1 colocalizes with histone deacetylase-2 (HDAC2, probably overcoming the suppression of transcriptional activity caused by Lingo1. These findings show that molecular adaptations mediated by NZF2b/7ZFMyt1 expression possibly lead to decreased responsiveness to the reinforcing properties of cocaine and play a prominent role in affecting the behavioral changes induced by the drug.

    Aims This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other outcomes. Methods and results Key demographic, clinical, and laboratory findings, along with baseline treatment, are reported and compared with those of patients in other recent clinical trials in heart failure. Compared with other recent trials, RED-HF enrolled more elderly [mean age 70 (SD 11.4) years], female (41%), and black (9%) patients. RED-HF patients more often had diabetes (46%) and renal impairment (72% had an estimated glomerular filtration rate <60 mL/min/1.73 m2). Patients in RED-HF had heart failure of longer duration [5.3 (5.4) years], worse NYHA class (35% II, 63% III, and 2% IV), and more signs of congestion. Mean EF was 30% (6.8%). RED-HF patients were well treated at randomization, and pharmacological therapy at baseline was broadly similar to that of other recent trials, taking account of study-specific inclusion/exclusion criteria. Median (interquartile range) haemoglobin at baseline was 112 (106–117) g/L. Conclusion The anaemic patients enrolled in RED-HF were older, moderately to markedly symptomatic, and had extensive co-morbidity. PMID:23329651

    Full Text Available Todd W RiceDivision of Allergy, Pulmonary, and Critical Care Medicine, Department of Medicine, Vanderbilt University School of Medicine, Nashville, TN, USAAbstract: Severely septic patients continue to experience excessive morbidity and mortality despite recent advances in critical care. Although significant resources have been invested in new treatments, almost all have failed to improve outcomes. An improved understanding of sepsis pathophysiology, including the complex interactions between inflammatory, coagulation, and fibrinolytic systems, has accelerated the development of novel treatments. Recombinant human activated protein C (rhAPC, or drotrecogin alfa (activated (DAA, is currently the only US Food and Drug Administration (FDA-approved medicine for the treatment of severe sepsis, and only in patients with a high risk of death. This review will discuss the treatment of severe sepsis, focusing on recent discoveries and unresolved questions about DAA’s optimal use. Increasing pharmacological experience has generated enthusiasm for investigating medicines already approved for other indications as treatments for severe sepsis. Replacement doses of hydrocortisone and vasopressin may reduce mortality and improve hypotension, respectively, in a subgroup of patients with catecholamine-refractory septic shock. In addition to discussing these new indications, this review will detail the provocative preliminary data from four promising treatments, including two novel modalities: antagonizing high mobility group box protein and inhibiting tissue factor (TF. Observational data from the uncontrolled administration of heparin or statins in septic patients will also be reviewed.Keywords: septic shock; drotrecogin alfa, vasopressin, new therapies, statins, high mobility group box protein

    The Pulsar Arecibo L-band Feed Array (PALFA) Survey uses the ALFA 7-beam receiver to search both inner and outer Galactic sectors visible from Arecibo (32° ≲ ℓ ≲ 77° and 168° ≲ ℓ ≲ 214°) close to the Galactic plane (|b| ≲ 5°) for pulsars. The PALFA survey is sensitive to sources fainter and more distant than have previously been seen because of Arecibo's unrivaled sensitivity. In this paper we detail a precursor survey of this region with PALFA, which observed a subset of the full region (slightly more restrictive in ℓ and |b| ≲ 1°) and detected 45 pulsars. Detections included 1 known millisecond pulsar and 11 previously unknown, long-period pulsars. In the surveyed part of the sky that overlaps with the Parkes Multibeam Pulsar Survey (36° ≲ ℓ ≲ 50°), PALFA is probing deeper than the Parkes survey, with four discoveries in this region. For both Galactic millisecond and normal pulsar populations, we compare the survey's detections with simulations to model these populations and, in particular, to estimate the number of observable pulsars in the Galaxy. We place 95% confidence intervals of 82,000 to 143,000 on the number of detectable normal pulsars and 9000 to 100,000 on the number of detectable millisecond pulsars in the Galactic disk. These are consistent with previous estimates. Given the most likely population size in each case (107,000 and 15,000 for normal and millisecond pulsars, respectively), we extend survey detection simulations to predict that, when complete, the full PALFA survey should have detected 1000{sub −230}{sup +330} normal pulsars and 30{sub −20}{sup +200} millisecond pulsars. Identical estimation techniques predict that 490{sub −115}{sup +160} normal pulsars and 12{sub −5}{sup +70} millisecond pulsars would be detected by the beginning of 2014; at the time, the PALFA survey had detected 283 normal pulsars and 31 millisecond pulsars, respectively. We attribute the deficiency in normal pulsar

    Full Text Available El sobrepeso infantil está asociado a sobrepeso/obesidad en la edad adulta. El tejido adiposo en obesos produce una cantidad incrementada de citoquinas proinflamatorias como el factor de necrosis tumoral alfa (TNF-a, ejerciendo un efecto deletéreo sobre la función vascular. El objetivo de este trabajo fue evaluar niveles de TNF-a en una población infantojuvenil con sobrepeso y su relación con otras variables. Se estudiaron 30 niños con sobrepeso (12 varones de edades entre 8-13 años, se midió circunferencia de cintura (CC e índice de masa corporal (IMC y fueron comparados con 20 controles de edad y sexo semejantes. Se consideró criterio de inclusión un IMC = 85 < 95 percentilo para edad y sexo. En ambos grupos se determinó: glucemia en ayunas (método glucosa oxidasa, insulina plasmática (ECLIA, fibrinógeno (Fg, método de Clauss, proteína C reactiva ultrasensible (uPCR, método inmunoturbidimétrico, TNF-a (ELISA, perfil lipídico (métodos enzimáticos, eritrosedimentación y se calculó el índice HOMA. Los datos se expresaron como mediana y rango intercuartil y con el coeficiente de Spearman se investigaron las correlaciones entre variables, considerándose significativo un p < 0.05. Los niveles de TNF-a fueron mayores en los sujetos con sobrepeso [15.4 (13.2-24.0 vs. 12.7 (11.2-14.8 pg/ml; p = 0.028]. También resultaron más elevados los valores de Fg, insulina plasmática, índice HOMA, uPCR y triglicéridos. El TNF-a se correlacionó con la CC (r = 0.654; p = 0.021. Los niveles elevados de TNF-a, uPCR y Fg encontrados confirman un estado proinflamatorio asociado a obesidad abdominal en la población estudiada.

    Full Text Available Background and objective RAP2B is one of the 50 novel candidate genes cloned from the differential expression cDNA libraries constructed in lung cancer cells. Though RAP2B contains conserved domain and belongs to Ras superfamily, the function of RAP2B in carcinogenesis is still poorly understood. The aim of this study is to explore the roles of RAP2B gene in carcinogenesis. Methods RT-PCR was applied to examine transcriptional status of RAP2B in the tumor and corresponding adjacent tissues collected from 27 patients with lung squamous cell carcinoma. RAP2B expression plasmid was constructed and transfected into Rat1 cells to evaluate the in vitro transformation ability through colony formation assay. Reporter gene assay was performed to reveal the relationship between RAP2B geneand NF-kappaB pathway. Results About 67% (18/27 of tumor tissues show higher mRNA expression than that in the corresponding adjacent normal tissues. Typical transforming focus formation was observed in Rat1 cells which were transfected with RAP2B gene. The reporter gene assay data showed that RAP2B activated NF-kappaB pathway more than3 folds compared with the mock vector. Conclusion RAP2B may be a novel candidate oncogene that plays important roles in carcinogenesis through activation of NF-kappaB pathway.

  8. Impacts of the Glucuronidase Genotypes UGT1A4, UGT2B7, UGT2B15 and UGT2B17 on Tamoxifen Metabolism in Breast Cancer Patients.

    Alicia Romero-Lorca

    Full Text Available Tamoxifen is used to prevent and treat estrogen-dependent breast cancer. It is described as a prodrug since most of its antiestrogen effects are exerted through its hydroxylated metabolites 4-OH-tamoxifen and endoxifen. In prior work, we correlated optimal plasma levels of these metabolites with certain genotypes of CYP2D6 and SULT1A2. This descriptive study examines correlations between concentrations of tamoxifen's glucuronide metabolites and genotypes UGT1A4 Pro24Thr, UGT1A4 Leu48Val, UGT2B7 His268Tyr, UGT2B15 Asp85YTyr UGT2B15 Lys523Thr and UGT2B17del in 132 patients with estrogen receptor-positive breast cancer under treatment with tamoxifen. Patients were genotyped by real-time and conventional PCR-RFLP. The glucuronides 4-OH-tamoxifen-N-glucuronide, 4-OH-tamoxifen-O-glucuronide and endoxifen-O-glucuronide were isolated from blood plasma and quantified using a high-pressure liquid chromatography-tandem mass spectrometry system. Individuals who were homozygous for UGT1A448VAL showed significantly lower mean concentrations of both glucuronide metabolites compared to subjects genotyped as wt/wt plus wt/48Val (p=0.037 and p=0.031, respectively. Women homozygous for UGT2B7268Tyr also showed mean substrate/product ratios of 4-OH-tamoxifen/4-OH-tamoxifen-O-glucuronide and 4-OH-tamoxifen/4-OH-tamoxifen-N-glucuronide indicative of reduced glucuronidase activity compared to wt homozygotes or to heterozygotes for the polymorphism (p=0.005 and p=0.003, respectively. In contrast, UGT2B15 Lys523Thr and UGT2B17del were associated with possibly increased enzyme activity. Patients with at least one variant allele UGT2B15523Thr showed significantly higher 4-OH-tamoxifen-O-glucuronide and endoxifen-glucuronide levels (p=0.023 and p=0.025, respectively indicating a variant gene-dose effect. Higher 4-OH-tamoxifen-N-glucuronide levels observed in UGT2B17del genotypes (p=0.042 could be attributed to a mechanism that compensates for the greater expression of

    Schizophrenia (SZ) is a common and complex psychiatric disorder that has a significant genetic component. The glutamatergic system is the major excitatory neurotransmitter system in the central nervous system, and is mediated by N-methyl-D-aspartate (NMDA) receptors. Disturbances in this system have been hypothesized to play a major role in SZ pathogenesis. Several studies have revealed that the NMDA receptor subunit 2B (GRIN2B) potentially associates with SZ and its psychiatric symptoms. In ...

    Background NR2B containing N-methyl-D-aspartate (NMDA) receptor plays an important role in the facilitation and maintenance of neuropathic pain. The discrete distribution of NR2B subunit in the central nervous system (CNS) may support reduced side effects of agents that act selectively at this site. Therefore, we investigated the hypothesis that a humoral autoimmune response targeting the NR2B subunit of NMDA receptor relieves pain like behaviours produced by peripheral injury.Methods Rats were immunized subcutaneously with NR2B-Keyhole Limpet Hemocyanin (NR2B-KLH) three times at two-week intervals. NR2B specific IgG titres in sera and cerebrospinal fluid were determined by indirect ELISA. Seven days after the third immunization, 2 of the 3 terminal branches of the sciatic nerve (tibial and common peroneal nerves) were tightly ligated. Behavioural testing was carried out on every other day after surgery, until 7 days after surgery. The lumbar spinal cord (L4-6) was removed on day 7 after ligation. The expression of NR2B protein in the lumbar spinal cord was determined using Western blotting.Results After the second vaccination, NR2B specific IgG in sera was detected to be >0.5 μg/ml in six of nine rats. After the third vaccination, all the immunized rats had >2.2 μg/ml. Titres of NR2B specific IgG in sera peaked 42 days post initial immunization and persisted for over 70 days. No NR2B specific IgG was detected in sera from PBS or KLH group.The behavioural thresholds in NR2B group were significantly higher than those in PBS and KLH groups on day 7 after ligation. NR2B specific IgG in CSF in NR2B group could not be detected on day 1 before spinal dissection; but could be detected on day 7 after surgery. The expression of NR2B protein in group NR2B was significantly lower than in PBS and KLH groups on day 7 after surgery.Conclusion The NR2B peptide could be used as a vaccine against neuropathic pain, which could be associated with reduction of NR2B protein in

    Full Text Available La Dirección de Recursos Humanos (DRH es una capacidad organizacional clasificada dentro de los activos intangibles y como tal puede convertirse en apoyo importante en la construcción de ventaja competitiva sostenida para la empresa. El presente estudio tiene el propósito de establecer hasta qué punto la DRH se constituye en soporte de la empresa colombiana para alcanzar dicha ventaja competitiva. La base empírica para la elaboración del artículo es información proveniente de la investigación "La gerencia de talento humano en las empresas medianas y grandes del occidente colombiano", en la que se encuestaron gerentes de recursos humanos de 257 empresas. Se consideraron las variables: grado de desarrollo de la DRH, ubicación del área en la estructura jerárquica, tamaño de la organización, sector económico, tipo de dirección, políticas de personal, factores claves de éxito y problemas en la gestión de RH. El grado de desarrollo de la DRH se estableció a partir de nueve componentes: percepción de autonomía del director de RH, asignación presupuestal al área, nivel educativo del director, nivel de liderazgo del director, existencia de plan estratégico en el área, estrategias innovadoras que el área ha propuesto en los últimos dos años, tiempo que el director debe dedicar a actividades no operativas ni rutinarias e indicadores de gestión que emplea el área de RH. La revisión de la literatura especializada permite concluir que los RH serán una fuente de ventaja competitiva sostenida siempre y cuando sean valiosos, escasos, relativamente inimitables e insustituibles, pero que no basta con ello si la firma carece de la organización para capitalizar el valor potencial de la gente. Esta es una capacidad que le corresponde a la DRH, que de esta manera se convierte en elemento clave para darle a los RH su característica de ventaja competitiva sostenida. Los hallazgos demuestran que el grado de desarrollo de la DRH est

  14. El alivio del dolor: un derecho humano universal

    2015-10-01

    Full Text Available El dolor es uno de los síntomas que más sufrimiento produce en cualquier enfermedad y constituye un problema básico de salud en todo el mundo. Sin embargo, con frecuencia no recibe el tratamiento adecuado por razones culturales, religiosas, actitudes de la sociedad y de los profesionales sanitarios, así como por motivos políticos y económicos. Desde el punto de vista ético, aliviar el dolor es un derecho del ser humano y una obligación de los profesionales sanitarios. La responsabilidad de los profesionales en lo que respecta a proporcionar un control adecuado del dolor está recogida en el Juramento Hipocrático y en la Declaración de Ginebra, que exige ante todo velar por la salud del paciente. Desde un punto de vista legislativo, la legislación internacional en materia de derechos humanos obliga a los Estados firmantes a proteger con todos los recursos a su alcance los derechos que la misma garantiza, sin establecer expresamente el derecho a un alivio adecuado del dolor. Sin embargo, el derecho a la salud lleva implícito el derecho a un adecuado tratamiento del dolor. La Constitución Española de 1978, en su artículo 43, reconoce el derecho a la protección de la salud y por tanto el derecho de los ciudadanos a recibir una asistencia sanitaria adecuada. Así mismo, el artículo 43 incluye que compete a los poderes públicos organizar y tutelar la salud pública a través de medidas preventivas y de las prestaciones y servicios necesarios. Aun no contemplando expresamente el derecho al alivio del dolor, garantiza una adecuada asistencia sanitaria que no puede dejar de lado un tema tan importante como es el tratamiento del dolor. La Organización Mundial de la Salud (OMS determinó que el alivio del dolor es un derecho fundamental y que incurre en una falta de ética grave aquel profesional de la salud que impida a un ser humano el acceso a la posibilidad de alivio del mismo. La OMS ha dictado los criterios indispensables para un

    Full Text Available Este trabajo busca analizar algunas contradicciones presentes en el discurso de los derechos humanos, y cuestionar la visión cronológica generalmente aceptada, que lleva a algunos autores a suponer que existe sólo un discurso sobre los derechos humanos. La breve revisión sobre la génesis y el desarrollo histórico de dicho discurso tiene por objeto discutir una nueva tipologia que permita distinguir y estudiar los diferentes discursos sobre derechos humanos que hoy se utilizan. Una segunda intención es demostrar cómo la criminología y la victimología, con restricciones menores, son discursos que pueden aportar conceptos útiles para una mejor comprensión y explicación de lo que acontece en torno a los derechos humanos.

  18. Frontotemporal dementia caused by CHMP2B mutation is characterised by neuronal lysosomal storage pathology

    DEFF Research Database (Denmark)

    Clayton, Emma L.; Mizielinska, Sarah; Edgar, James R.;

    2015-01-01

    Mutations in the charged multivesicular body protein 2B (CHMP2B) cause frontotemporal dementia (FTD). We report that mice which express FTD-causative mutant CHMP2B at physiological levels develop a novel lysosomal storage pathology characterised by large neuronal autofluorescent aggregates....... The aggregates are an early and progressive pathology that occur at 3 months of age and increase in both size and number over time. These autofluorescent aggregates are not observed in mice expressing wild-type CHMP2B, or in non-transgenic controls, indicating that they are a specific pathology caused by mutant...... in human CHMP2B mutation brain than in neurodegenerative disease or age-matched control brains. These data suggest that lysosomal storage pathology is the major neuronal pathology in FTD caused by CHMP2B mutation. Recent evidence suggests that two other genes associated with FTD, GRN and TMEM106B...

    2016-10-01

    Rap2b, a member of the guanosine triphosphate-binding proteins, is widely up-regulated in many types of tumors. However, the functional role of Rap2b in tumorigenesis of lung cancer remains to be fully elucidated. In this study, we investigated the effect of Rap2b on the lung cancer malignant phenotype, such as cell proliferation and metastasis. We found that Rap2b could promote the abilities of lung cancer cell wound healing, migration, and invasion via increasing matrix metalloproteinase-2 enzyme activity. Furthermore, Rap2b overexpression could increase the phosphorylation level of extracellular signal-regulated protein kinases 1/2. In conclusion, our results suggested that Rap2b may be a potential therapeutic target for lung cancer. PMID:26671640

    During chromatin-regulated processes, the histone H2A-H2B heterodimer functions dynamically in and out of the nucleosome. Although detailed crystal structures of nucleosomes have been established, that of the isolated full-length H2A-H2B heterodimer has remained elusive. Here, we have determined the solution structure of human H2A-H2B by NMR coupled with CS-Rosetta. H2A and H2B each contain a histone fold, comprising four α-helices and two β-strands (α1-β1-α2-β2-α3-αC), together with the long disordered N- and C-terminal H2A tails and the long N-terminal H2B tail. The N-terminal αN helix, C-terminal β3 strand, and 310 helix of H2A observed in the H2A-H2B nucleosome structure are disordered in isolated H2A-H2B. In addition, the H2A α1 and H2B αC helices are not well fixed in the heterodimer, and the H2A and H2B tails are not completely random coils. Comparison of hydrogen-deuterium exchange, fast hydrogen exchange, and {(1)H}-(15)N hetero-nuclear NOE data with the CS-Rosetta structure indicates that there is some conformation in the H2A 310 helical and H2B Lys11 regions, while the repression domain of H2B (residues 27-34) exhibits an extended string-like structure. This first structure of the isolated H2A-H2B heterodimer provides insight into its dynamic functions in chromatin. PMID:27181506

    Phox2b is an essential transcription factor for the development of the autonomic nervous system. Mice carrying one invalidated Phox2b allele (Phox2b(+/-)) show mild autonomic disorders including sleep apneas, and impairments in chemosensitivity and thermoregulation that recover within 10days of postnatal age. Because Phox2b is not expressed above the pons nor in the cerebellum, this mutation is not expected to affect brain development and cognitive functioning directly. However, the transient physiological disorders in Phox2b(+/-) mice might impair neurodevelopment. To examine this possibility, we conducted a behavioral test battery of emotional, motor, and cognitive functioning in adult Phox2b(+/-) mice and their wildtype littermates (Phox2b(+/+)). Adult Phox2b(+/-) mice showed altered exploratory behavior in the open field and in the elevated plus maze, both indicative of anxiety. Phox2b(+/-) mice did not show cognitive or motor impairments. These results suggest that also mild autonomic control deficits may disturb long-term emotional development. PMID:25582512

  14. Insights into CYP2B6-mediated drug–drug interactions

    2016-09-01

    Full Text Available Mounting evidence demonstrates that CYP2B6 plays a much larger role in human drug metabolism than was previously believed. The discovery of multiple important substrates of CYP2B6 as well as polymorphic differences has sparked increasing interest in the genetic and xenobiotic factors contributing to the expression and function of the enzyme. The expression of CYP2B6 is regulated primarily by the xenobiotic receptors constitutive androstane receptor (CAR and pregnane X receptor (PXR in the liver. In addition to CYP2B6, these receptors also mediate the inductive expression of CYP3A4, and a number of important phase II enzymes and drug transporters. CYP2B6 has been demonstrated to play a role in the metabolism of 2%–10% of clinically used drugs including widely used antineoplastic agents cyclophosphamide and ifosfamide, anesthetics propofol and ketamine, synthetic opioids pethidine and methadone, and the antiretrovirals nevirapine and efavirenz, among others. Significant inter-individual variability in the expression and function of the human CYP2B6 gene exists and can result in altered clinical outcomes in patients receiving treatment with CYP2B6-substrate drugs. These variances arise from a number of sources including genetic polymorphism, and xenobiotic intervention. In this review, we will provide an overview of the key players in CYP2B6 expression and function and highlight recent advances made in assessing clinical ramifications of important CYP2B6-mediated drug–drug interactions.

    The sulfonylurea receptor 2B (SUR2B) forms the regulatory subunit of ATP-sensitive potassium (KATP) channels in vascular smooth muscle. Phosphorylation of the SUR2B nucleotide binding domains (NBD1 and NBD2) by protein kinase A results in increased channel open probability. Here, we investigate the effects of phosphorylation on the structure and nucleotide binding properties of NBD1. Phosphorylation sites in SUR2B NBD1 are located in an N-terminal tail that is disordered. Nuclear magnetic resonance (NMR) data indicate that phosphorylation of the N-terminal tail affects multiple residues in NBD1, including residues in the NBD2-binding site, and results in altered conformation and dynamics of NBD1. NMR spectra of NBD1 lacking the N-terminal tail, NBD1-ΔN, suggest that phosphorylation disrupts interactions of the N-terminal tail with the core of NBD1, a model supported by dynamic light scattering. Increased nucleotide binding of phosphorylated NBD1 and NBD1-ΔN, compared with non-phosphorylated NBD1, suggests that by disrupting the interaction of the NBD core with the N-terminal tail, phosphorylation also exposes the MgATP-binding site on NBD1. These data provide insights into the molecular basis by which phosphorylation of SUR2B NBD1 activates KATP channels. PMID:26198630

    Group B Streptococcus (GBS) expresses 3 structurally distinct pilus types (1, 2a, and 2b) identified as important virulence factors and vaccine targets. These pili are heterotrimeric polymers, covalently assembled on the cell wall by sortase (Srt) enzymes. We investigated the pilus-2b biogenesis mechanism by using a multidisciplinary approach integrating genetic, biochemical, and structural studies to dissect the role of the 2 pilus-2b-associated Srts. We show that only 1 sortase (SrtC1-2b) is responsible for pilus protein polymerization, whereas the second one (Srt2-2b) does not act as a pilin polymerase, but similarly to the housekeeping class A Srt (SrtA), it is involved in cell-wall pilus anchoring by targeting the minor ancillary subunit. Based on its function and sequence features, Srt2-2b does not belong to class C Srts (SrtCs), nor is it a canonical member of any other known family of Srts. We also report the crystal structure of SrtC1-2b at 1.9 Å resolution. The overall fold resembles the typical structure of SrtCs except for the N-terminal lid region that appears in an open conformation displaced from the active site. Our findings reveal that GBS pilus type 2b biogenesis differs significantly from the current model of pilus assembly in gram-positive pathogens.

    The Quality Data Model (QDM) is an established standard for representing electronic clinical quality measures on electronic health record (EHR) repositories. The Informatics for Integrated Biology and the Bedside (i2b2) is a widely used platform for implementing clinical data repositories. However, translation from QDM to i2b2 is challenging, since QDM allows for complex queries beyond the capability of single i2b2 messages. We have developed an approach to decompose complex QDM algorithms into workflows of single i2b2 messages, and execute them on the KNIME data analytics platform. Each workflow operation module is composed of parameter lists, a template for the i2b2 message, an mechanism to create parameter updates, and a web service call to i2b2. The communication between workflow modules relies on passing keys ofi2b2 result sets. As a demonstration of validity, we describe the implementation and execution of a type 2 diabetes mellitus phenotype algorithm against an i2b2 data repository. PMID:27570665

    2015-07-01

    Porcine Circovirus Type 2 (PCV2) is a worldwide distributed virus and is considered an important emerging pathogen related to several distinct disease syndromes in pigs. PCV2 strains are classified into three genotypes: PCV2a, with five subtypes (2A-2E), PCV2b with three subtypes (1A-1C) and PCV2c, only found in Denmark. Recently, several reports suggested the circulation of newly emerging PCV2b mutants (mPCV2b) isolated from pigs with PCVAD in cases of suspected vaccine failure. In this work, we report for the first time the identification of mPCV2b in pigs from Uruguay, providing an additional evidence of a global circulation. Complete genome characterization and phylogenetic analysis reveal that Uruguayan strains, as well as mPCV2b previously reported are closely related to other sequences already classified as PCV2b-1C. Furthermore, results showed that mPCV2b presented different genetic markers in the capsid protein compared with classical PCV2a/b strains. Further investigation about antigenic shift of the mPCV2b strains including the Uruguayan isolates is needed.

    Hydroxyapatite(HA) nanoparticles were prepared by coprecipitation-hydrothermal synthesis and their exosyndrome was estimated via transmission electron microscopy. Agarose gel electrophoresis and ultraviolet spectrophotometry were used to evaluate the ability of HA to bind NR2B-siRNA at different pH values and at different HA-NR2B-siRNA ratios. And the stability of the complex in saline was also evaluated. The effect of HA/NR2B-siRNA complex on chronic inflammatory pain was evaluated in vivo in mice. Transmission electron microscopy(TEM) reveals that HA nanoparticles are thin strips or short rod in shape and the one-dimensional particle size of HA nanoparticles is 40-50 nm. Under the acid or neutral condition, the Zeta potential of HA is positive; nanoparticles can completely bind NR2B-siRNA when the HA:NR2B-siRNA ratio is at or larger than 35-1; while under the alkaline condition, the affinity of HA to NR2B-siRNA is rather weak. HA/NR2B-siRNA complex is not dissociated when being resuspended in saline. The nociception of the tonic phase induced by formalin is significantly reduced in the HA/NR2B-siRNA treated mice as compared with the controls. Therefore, HA may be a new siRNA nano-vector material.

A partir dos anos de 1970, a interação de movimentos camponeses da Igreja Católica progressista e da rede transnacional de direitos humanos confluiu na produção dessa ideia da posse da terra como um direito humano, que marcou não apenas a luta pela terra no Brasil, como também influenciou a forma como o próprio movimento de direitos humanos foi construído no país e na maneira como ele se inseriu nessa rede transnacional de ativistas.This article seeks to analyze, within the recent history of social movements that struggle for agrarian reform in Brazil today, the build of the land rights as a human right. Since the 1970s, the interaction between peasant movements, the progressive church and the transnational network of human rights has converged into this idea that the land rights are a human right, which not only has marked the character of the struggle for land in Brazil, but has also influenced the way in which the human rights movement has been constructed in the country and how it has taken its place within the transnational network of human rights activism.

  18. Coupling of glucose deprivation with impaired histone H2B monoubiquitination in tumors.

    Directory of Open Access Journals (Sweden)

    Yasuyo Urasaki

    Full Text Available Metabolic reprogramming is associated with tumorigenesis. However, glucose metabolism in tumors is poorly understood. Here, we report that glucose levels are significantly lower in bulk tumor specimens than those in normal tissues of the same tissue origins. We show that mono-ubiquitinated histone H2B (uH2B is a semi-quantitative histone marker for glucose. We further show that loss of uH2B occurs specifically in cancer cells from a wide array of tumor specimens of breast, colon, lung and additional 23 anatomic sites. In contrast, uH2B levels remain high in stromal tissues or non-cancerous cells in the tumor specimens. Taken together, our data suggest that glucose deficiency and loss of uH2B are novel properties of cancer cells in vivo, which may represent important regulatory mechanisms of tumorigenesis.

    NR2B subunits are involved in regulating aging, in particular, age-related learning and memory deficits. We examined 19-month-old NR2B transgenic mice and their littermate controls. First, we detected expression of the NR2B subunit gene, Grin2b, in the neocortex of transgenic mice using real-time PCR. Next, we used microarrays to examine differences in neocortical gene expression. Pathway and signal-net analyses identified multiple pathways altered in the transgenic mice, in-cluding the P53, Jak-STAT, Wnt, and Notch pathways, as wel as regulation of the actin cytoskeleton and neuroactive ligand-receptor interactions. Further signal-net analysis highlighted the P53 and insulin-like growth factor pathways as key regulatory pathways. Our results provide new insight into understanding the molecular mechanisms of NR2B regulated age-related memory storage, normal organismal aging and age-related disease.

    2008-07-01

    Full Text Available A deficiência de alfa-1 antitripsina é um distúrbio genético de descoberta recente e que ocorre com freqüência comparável à da fibrose cística. Resulta de diferentes mutações no gene SERPINA1 e tem diversas implicações clínicas. A alfa-1 antitripsina é produzida principalmente no fígado e atua como uma antiprotease. Tem como principal função inativar a elastase neutrofílica, impedindo a ocorrência de dano tecidual. A mutação mais freqüentemente relacionada à doença clínica é o alelo Z, que determina polimerização e acúmulo dentro dos hepatócitos. O acúmulo e a conseqüente redução dos níveis séricos de alfa-1 antitripsina determinam, respectivamente, doença hepática e pulmonar, sendo que esta se manifesta principalmente sob a forma de enfisema de aparecimento precoce, habitualmente com predomínio basal. O diagnóstico envolve a detecção de níveis séricos reduzidos de alfa-1 antitripsina e a confirmação fenotípica. Além do tratamento usual para doença pulmonar obstrutiva crônica, existe atualmente uma terapia específica com infusão de concentrados de alfa-1 antitripsina. Essa terapia de reposição, aparentemente segura, ainda não teve a eficácia clínica definitivamente comprovada, e o custo-efetividade também é um tema controverso e ainda pouco abordado. Apesar da sua importância, não existem dados epidemiológicos brasileiros a respeito da prevalência da doença ou da freqüência de ocorrência dos alelos deficientes. O subdiagnóstico também tem sido uma importante limitação tanto para o estudo da doença quanto para o tratamento adequado dos pacientes. Espera-se que a criação do Registro Internacional de Alfa-1 venha a resolver essas e outras importantes questões.Alpha-1 antitrypsin deficiency is a recently identified genetic disease that occurs almost as frequently as cystic fibrosis.

    Directory of Open Access Journals (Sweden)

    Jael R Malenke

    Full Text Available Detoxification enzymes play a key role in plant-herbivore interactions, contributing to the on-going evolution of ecosystem functional diversity. Mammalian detoxification systems have been well studied by the medical and pharmacological industries to understand human drug metabolism; however, little is known of the mechanisms employed by wild herbivores to metabolize toxic plant secondary compounds. Using a wild rodent herbivore, the desert woodrat (Neotoma lepida, we investigated genomic structural variation, sequence variability, and expression patterns in a multigene subfamily involved in xenobiotic metabolism, cytochrome P450 2B (CYP2B. We hypothesized that differences in CYP2B expression and sequence diversity could explain differential abilities of woodrat populations to consume native plant toxins. Woodrats from two distinct populations were fed diets supplemented with either juniper (Juniperus osteosperma or creosote bush (Larrea tridentata, plants consumed by woodrats in their respective desert habitats. We used Southern blot and quantitative PCR to determine that the genomic copy number of CYP2B in both populations was equivalent, and similar in number to known rodent copy number. We compared CYP2B expression patterns and sequence diversity using cloned hepatic CYP2B cDNA. The resulting sequences were very diverse, and clustered into four major clades by amino acid similarity. Sequences from the experimental treatments were distributed non-randomly across a CYP2B tree, indicating unique expression patterns from woodrats on different diets and from different habitats. Furthermore, within each major CYP2B clade, sequences shared a unique combination of amino acid residues at 13 sites throughout the protein known to be important for CYP2B enzyme function, implying differences in the function of each major CYP2B variant. This work is the most comprehensive investigation of the genetic diversity of a detoxification enzyme subfamily in a

    International Nuclear Information System (INIS)

    To determine whether Interferon-alpha-2b (IFN-α2b) can modulate the autophagic response in hepatocellular carcinoma cells. Hepatocellular carcinoma cells were treated with IFN-α2b. Autophagy was assessed by acridine orange staining, GFP-LC3 dotted assay, transmission electron microscopy and immunoblotting. Acridine orange staining showed that IFN-α2b triggered the accumulation of acidic vesicular and autolysosomes in HepG2 cells. The acridine orange HepG2 cell ratios were (4.3±1.0)%, (6.9±1.4)%, and (13.1±2.3)%, respectively, after treatment with 100, 1,000, and 10,000 IU/mL IFN-α2b for 48 h. A markedly punctate pattern was observed in HepG2 cells treated with 10,000 IU/mL IFN-α2b for 48 h, but only diffuse and weakly fluorescent GFP-LC3 puncta was observed in control cells. HepG2 cells treated with 10,000 IU/mL IFN-α2b for 48 h developed autophagosome-like characteristics, including single- or double-membrane vacuoles containing intact and degraded cellular debris. The Beclin1 and LC3-II protein expression was up-regulated by IFN-α2b treatment. Autophagy can be induced in a dose-dependent manner by treatment with IFN-α2b in HepG2 cells, and the Beclin1 signaling pathway was stimulated by IFN-α2b

    Neuroblastoma is an embryonal pediatric tumor that originates from the developing sympathetic nervous system and shows a broad range of clinical behavior, ranging from fatal progression to differentiation into benign ganglioneuroma. In experimental neuroblastoma systems, retinoic acid (RA) effectively induces neuronal differentiation, and RA treatment has been therefore integrated in current therapies. However, the molecular mechanisms underlying differentiation are still poorly understood. We here investigated the role of transcription factor activating protein 2 beta (TFAP2B), a key factor in sympathetic nervous system development, in neuroblastoma pathogenesis and differentiation. Microarray analyses of primary neuroblastomas (n = 649) demonstrated that low TFAP2B expression was significantly associated with unfavorable prognostic markers as well as adverse patient outcome. We also found that low TFAP2B expression was strongly associated with CpG methylation of the TFAP2B locus in primary neuroblastomas (n = 105) and demethylation with 5-aza-2'-deoxycytidine resulted in induction of TFAP2B expression in vitro, suggesting that TFAP2B is silenced by genomic methylation. Tetracycline inducible re-expression of TFAP2B in IMR-32 and SH-EP neuroblastoma cells significantly impaired proliferation and cell cycle progression. In IMR-32 cells, TFAP2B induced neuronal differentiation, which was accompanied by up-regulation of the catecholamine biosynthesizing enzyme genes DBH and TH, and down-regulation of MYCN and REST, a master repressor of neuronal genes. By contrast, knockdown of TFAP2B by lentiviral transduction of shRNAs abrogated RA-induced neuronal differentiation of SH-SY5Y and SK-N-BE(2)c neuroblastoma cells almost completely. Taken together, our results suggest that TFAP2B is playing a vital role in retaining RA responsiveness and mediating noradrenergic neuronal differentiation in neuroblastoma. PMID:26598443

Este virus se encuentra dividido en dos subgrupos antigénicos bien definidos, A y B. Los estudios de variabilidad genética, se focalizan en la glicoproteína G, debido al alto grado de variabilidad genética y antigénica que presenta esta entre los diversos aislamientos. En Cuba fue detectado por primera vez en 1964 como el agente causal del brote de bronquiolitis desatado este año. Este virus causa infecciones leves como severas en hospederos susceptibles. Dichas infecciones son prevenidas con el empleo de medicamentos profilácticos como por ejemplo: péptidos sintéticos, anticuerpos policlonales y monoclonales humanizados, antígenos virales recombinantes, sin embargo, el más aplicado es el palivizumab (anticuerpo monoclonal humanizado. Se ha observado, que con el empleo de este anticuerpo se ha logrado disminuir a nivel mundial la tasa de hospitalización de los hospederos más susceptibles. Actualmente se investigan otros medicamentos los cuales presentan un modo de acción diferente al palivizumab.

    Full Text Available RESUMO El presente artículo pretende desarrollar conceptualmente algunas nociones esenciales sobre la paz y el derecho, y como la relación entre estos sirve para el análisis que se realiza en el presente trabajo sobre la necesidad de que el derecho humano a la paz se convierta en una realidad jurídica de cumplimiento para los Estados. Para esto resulta importante revisar brevemente el pensamiento histórico de cuatro juristas excepcionales que en diferentes momentos históricos de la humanidad con sus ideas y pensamiento han marcado e influenciado el pensamiento moderno del derecho así como el concepto de la relación entre paz y derecho.Para Kant el estado de paz perpetua sólo se la podía garantizar a través de la utilización del derecho como instrumento; por su parte Kelsen basaba su teoría en la idea esencial sobre la unidad y/o objetividad del ordenamiento jurídico, la primacía del derecho internacional, el carácter “parcial” de los ordenamientos jurídicos nacionales constituía el eje primordial para garantizar la paz en el mundo. Norberto Bobbio introduce el término “pacifismo jurídico “ señalando que la guerra es el resultado de un Estado sin derecho carente de normas eficaces para legalizar los conflictos puesto que las distintas corrientes pacifistas se ocupan sobre todo de la situación de las relaciones internacionales, respecto a que la guerra es un dato permanente, el pacifismo jurídico hace referencia al proceso de formación de una sociedad internacional, planteando que los conflictos suscitados entre los estados no deben resolverse mediante las guerras. Finalmente Danilo Zolo señala que la paz no se puede establecer mediante los ordenamientos jurídicos o institucionales su propuesta está enfocada al proceso de transición que debe existir de un pacifismo cosmopolita a un pacifismo débil, lo que requiere de una red de instituciones internacionales, nacionales y regionales, que den paso a una

    The magnetic and transport properties of PrIr(2)B(2) and PrIr(2)B(2)C have been investigated by dc and ac magnetic susceptibility, specific heat, electrical resistivity and magnetoresistance measurements. PrIr(2)B(2) forms in CaRh(2)B(2)-type orthorhombic crystal structure (space group Fddd). At low fields the dc magnetic susceptibility of PrIr(2)B(2) exhibits a sharp anomaly near 46 K which is followed by an abrupt increase below 10 K with a peak at 6 K, and split-up in ZFC and FC data below 46 K. In contrast, the specific heat exhibits only a broad Schottky type hump near 9 K which indicates that there is no long range magnetic order in this compound. The thermo-remanent magnetization is found to decay very slowly with a mean relaxation time τ = 3917 s. An ac magnetic susceptibility measurement also observes two sharp anomalies; the peak positions strongly depend on the frequency and shift towards high temperature with an increase in frequency, obeying the Vogel-Fulcher law as expected for a canonical spin-glass system. The two spin-glass transitions occur at freezing temperatures T(f1) = 36 K and T(f2) = 3.5 K with shifts in the freezing temperatures per decade of frequency δT(f1) = 0.044 and δT(f2) = 0.09. An analysis of the frequency dependence of the transition temperature with critical slowing down, τ(max)/τ(0) = [(T(f)-T(SG))/T(SG)](-zν), gives τ(0) = 10(-7) s and exponent zν = 8, and the Vogel-Fulcher law gives an activation energy of 84 K for T(f1) and 27.5 K for T(f2). While zν = 8 is typical for spin-glass system, the characteristic relaxation time τ(0) = 10(-7) s is very large and comparable to that of superspin-glass systems. An addition of C in PrIr(2)B(2) leads to PrIr(2)B(2)C which forms in LuNi(2)B(2)C-type tetragonal structure (space group I4/mmm) and remains paramagnetic down to 2 K. The specific heat data show a broad Schottky type anomaly, which could be fairly reproduced with CEF analysis which suggests that the ground state is a

    Full Text Available En el Sistema Interamericano de Protección de los Derechos Humanos, se prevé que los litigios entre los Estados y las víctimas de violaciones de derechos humanos o sus representantes puedan resolverse a través de un acuerdo amistoso. En este arreglo, llevado a cabo ante los órganos regionales de protección de los derechos humanos, el Estado se somete por voluntad propia a un proceso de solución amistosa, que no implica per se un reconocimiento de responsabilidad internacional por parte suya, sino apenas un cumplimiento de buena fe de los propósitos de la Convención, proceso en el que se compromete a investigar y juzgar a los responsables, y adopta compromisos en materia de reparación a losafectados; las víctimas, por su parte, renuncian a llevar el caso ante la Corte Interamericana de Derechos Humanos; y la Comisión Interamericana vela por la coherencia del acuerdo en relación con la normatividad interamericana y ostenta un papel de observador independiente. ¿En qué consisten estos acuerdos?, ¿qué posibilidades y límites ofrecen para las partes enfrentadas? y, sobre todo, ¿qué clase de reparación ofrecen para las víctimas de violaciones de derechos humanos?, son las cuestiones por resolver en el presente artículo.

    Full Text Available El artículo se centra en el estudio de la protección de los derechos humanos en el sistema interamericano, creado por los Estados de este continente en el marco de la Organización de Estados Americanos (OEA tomando como referente uno de sus principios esenciales: el respeto y garantía de los derechos de la persona humana. Se estudian los instrumentos interamericanos generales y constitucionales del sistema: la Declaración Americana de los Derechos y Deberes del Hombre (1948 y la Convención Americana sobre Derechos Humanos (1969, considerando los órganos principales encargados del control y tutela de las obligaciones estatales de respeto y garantía de los derechos reconocidos en dichos instrumentos: la Comisión y la Corte Interamericanas de Derechos Humanos. Se concluye que si bien constituye una conquista significativa el reconocimiento internacional de los derechos humanos, queda aún mucho camino por recorrer para lograr la efectiva protección de los mismos en el orden internacional, particularmente en el ámbito del sistema interamericano donde se advierten deficiencias políticas, estructurales y de procedimiento que dificultan el perfeccionamiento de su labor en una región donde persiste una situación generalizada de violación de los derechos humanos, con énfasis en los derechos económicos, sociales y culturales de la población latinoamericana.

  14. Recombination luminescence in Li2B4O7 doped with manganese and copper

    International Nuclear Information System (INIS)

    Non-irradiated and irradiated ceramics of Li2B4O7:Mn, Li2B4O7:Mn,Be, and Li2B4O7:Mn,Cu were studied using electron paramagnetic resonance and luminescence spectroscopy. The emission of Mn2+ centres is observed in the thermoluminescence spectra of the low-temperature and dosimetric high-temperature glow peaks in irradiated samples. Arguments are given in favour of hole mobility being responsible for the dosimetric thermoluminescence peak at 490 K in Li2B4O7:Mn. The co-doping of Li2B4O7:Mn with Cu+ is shown to increase the sensitivity of the material to ionizing radiation. -- Highlights: ► Doped Li2B4O7 ceramics were studied by EPR and optical spectroscopy. ► In Li2B4O7:Mn ceramics Mn2+ emission is observed for the TSL peaks at 90 and 490 K ► We propose the release of holes to be responsible for the dosimetric peak at 490 K

    Development of pulmonary hypertension is a common and deadly complication of interstitial lung disease. Little is known regarding the cellular and molecular mechanisms that lead to pulmonary hypertension in patients with interstitial lung disease, and effective treatment options are lacking. The purpose of this study was to examine the adenosine 2B receptor (A(2B)R) as a regulator of vascular remodeling and pulmonary hypertension secondary to pulmonary fibrosis. To accomplish this, cellular and molecular changes in vascular remodeling were monitored in mice exposed to bleomycin in conjunction with genetic removal of the A(2B)R or treatment with the A(2B)R antagonist GS-6201. Results demonstrated that GS-6201 treatment or genetic removal of the A(2B)R attenuated vascular remodeling and hypertension in our model. Furthermore, direct A(2B)R activation on vascular cells promoted interleukin-6 and endothelin-1 release. These studies identify a novel mechanism of disease progression to pulmonary hypertension and support the development of A(2B)R antagonists for the treatment of pulmonary hypertension secondary to interstitial lung disease.

    Mesenchymal stem cells (MSCs) are a reliable resource for tissue regeneration, but the molecular mechanism underlying directed differentiation remains unclear; this has restricted potential MSC applications. Histone methylation, controlled by histone methyltransferases and demethylases, may play a key role in MSCs differentiation. Previous studies determined that KDM2B can regulate the cell proliferation and osteo/dentinogenic differentiation of MSCs. It is not known whether KDM2B is involved in the other cell lineages differentiation of MSCs. Here we used the stem cells from apical papilla (SCAPs) to study the role of KDM2B on the chondrogenic differentiation potentials in MSCs. In this study, Gain- and loss-of-function assays were applied to investigate the role of KDM2B on the chondrogenic differentiation. Alcian Blue Staining and Quantitative Analysis were used to investigate the synthesis of proteoglycans by chondrocytes. Real-time RT-PCR was used to detect the expressions of chondrogenesis related genes. The Alcian Blue staining and Quantitative Analysis results revealed that overexpression of KDM2B decreased the proteoglycans production, and real-time RT-PCR results showed that the expressions of the chondrogenic differentiation markers, COL1, COL2 and SOX9 were inhibited by overexpression of KDM2B in SCAPs. On the contrary, depletion of KDM2B increased the proteoglycans production, and inhibited the expressions of COL1, COL2 and SOX9. In conclusion, our results indicated that KDM2B is a negative regulator of chondrogenic differentiation in SCAPs and suggest that inhibition of KDM2B might improve MSC mediated cartilage regeneration.

    To design a peptide disrupting the interaction between N-methyl-d-aspartate receptors-2B (NR2B) and postsynaptic density protein-95 (PSD-95), a gene fragment encoding a chimeric peptide was constructed using polymerase chain reaction and ligated into a novel expression vector for recombinant expression in a T7 RNA polymerase-based expression system. The chimeric peptide contained a fragment of the cell membrane transduction domain of the human immunodeficiency virus type1 (HIV-1) Tat, a influenza virus hemagglutinin (HA) epitope-tag, and the C-terminal 9 amino acids of NR2B (NR2B9c). We named the chimeric peptide Tat-HA-NR2B9c. The expression plasmid contained a gene fragment encoding the Tat-HA-NR2B9c was ligated to the C-terminal fragment of l-asparaginase (AnsB-C) via a unique acid labile Asp-Pro linker. The recombinant fusion protein was expressed in inclusion body in Escherichia coli under isopropyl β-d-1-thiogalactopyranoside (IPTG) and purified by washing with 2M urea, solubilizing in 4M urea, and then ethanol precipitation. The target chimeric peptide Tat-HA-NR2B9c was released from the fusion partner following acid hydrolysis and purified by isoelectric point precipitation and ultrafiltration. SDS-PAGE analysis and MALDI-TOF-MS analysis showed that the purified Tat-HA-NR2B9c was highly homogeneous. Furthermore, we investigated the effects of Tat-HA-NR2B9c on ischemia-induced cerebral injury in the rats subjected to middle cerebral artery occlusion (MCAO) and reperfusion, and found that the peptide reduced infarct size and improved neurological functions.

    Social media is a new, yet very prominent concept in present marketing communication. It has been growing steadily and became popular among marketers both in business-to-customer (B2C) and business-to-business (B2B). However, there has been more research done on how to apply and utilize social media in the B2C scenario and there are fewer explanations about B2B cases. Therefore, it was interesting to do research and analysis on how B2B companies operate, what are the factors influencing socia...

    Since the identification of canine parvovirus type 2, three variants have subsequently been observed differing from the historical CPV-2 and each other by 1-2 amino acids only. As a result there has been considerable research into differential diagnostics, with some researchers indicating there is a need for new vaccines containing different strains of CPV-2. In this study we investigated whether vaccination with a CPV-2b containing vaccine would induce cross-reactive antibody responses to the other CPV-2 variants. Two studies where dogs were vaccinated with a multivalent vaccine, subsequently challenged with CPV-2b and sera samples analysed are presented. Six week old pups with defined serological status were vaccinated twice, three weeks apart and challenged either 5 weeks (MDA override study) or one year after vaccination (duration of immunity study). Sera samples were collected before each vaccination and at periods throughout each study. In each study the antibody profiles were very similar; serological responses against CPV-2a, CPV-2b and CPV-2c were higher than those for CPV-2. Nevertheless, responses against CPV-2 were well above levels considered clinically protective. In each study dogs also showed a rapid increase in antibody titres following vaccination, reached a plateau following second vaccination with a slight decline to challenge after which rapid anamnestic responses were seen. Evaluation of the serological responses suggests vaccination with CPV-2b would cross-protect against CPV-2a and CPV-2c, as well as against CPV-2 which is now extinct in the field. In conclusion we have demonstrated that vaccination of minimum aged dogs with a multivalent vaccine containing the CPV-2b variant strain will induce serological responses which are cross-reactive against all currently circulating field strains, CPV-2a and CPV-2c, and the now extinct field strain CPV-2.

    Full Text Available El microquimerismo humano se define como la presencia dentro de un individuo de una pequeña población de células originadas en un individuo genéticamente distinto. El microquimerismo adquirido de forma natural se desarrolla a lo largo del embarazo, como una consecuencia del ampliamente demostrado tráfico bidireccional transplacentario de células. Esta trasferencia resulta en un estado microquimérico a décadas posparto, tanto para la madre (microquimerismo fetal como para su progenie (microquimerismo materno. Aún más, el establecimiento de esta condición ocurre, iatrogénicamente, posterior al trasplante de órganos y la transfusión de sangre. Actualmente el microquimerismo es un tema de gran interés alrededor del mundo, dadas sus múltiples posibles implicaciones en la salud y en la enfermedad. Su estudio comenzó a raíz del potencial para el desarrollo de técnicas de diagnóstico prenatal no invasivo, en el presente se tienen amplias expectativas de su utilidad en la terapia con células madre. Se ha propuesto que el microquimerismo podría estar implicado en la patogénesis de ciertas enfermedades autoinmunes, en la reparación de tejidos, el cáncer y la inducción de tolerancia.Human microchimerism is defined as the presence within one individual of a small population of cells originated in a genetically distinct individual. Naturally acquired microchimerism develops throughoutpregnancy, as a consequence of the clearly demonstrated bidirectional transplacental traffic of cells. This transference results in a long-term postpartum microchimeric state for both, the mother (fetal microchimerism and her progeny (maternal microchimerism. Furthermore, the establishment of this condition occurs, iatrogenically, after organ transplantation and blood transfusions. Microchimerism is subject of current interest worldwide, given its multiple possible implications for health and disease. Initial investigation was promoted because of its
