    Treatment persistence and cost of therapy for patients with chronic hepatitis C (CHC) treated with peginterferon alfa-2a plus ribavirin and peginterferon alfa-2b plus ribavirin were evaluated. This retrospective database analysis used eligibility, pharmacy, and medical claims data from a large U.S. health plan for patients with CHC treated with peginterferon alfa-2a plus ribavirin and peginterferon alfa-2b plus ribavirin from January 2002 through June 2006. For the purposes of this analysis, the study population included all hepatitis C virus (HCV) genotypes. Comparable groups for assessment of outcomes were constructed using propensity score matching to reduce the effect of known sources of bias. Outcome variables included treatment persistence and annualized overall and HCV-attributable health care costs. A total of 1783 matched pairs were analyzed. Compared with patients receiving peginterferon alfa-2a plus ribavirin, patients receiving peginterferon alfa-2b plus ribavirin were 18% less likely to be persistent with therapy at week 48 (p = 0.013). During the first six months of follow-up, mean all-cause costs (p = 0.0368) and HCV-attributable costs (p costs (p = 0.0060) and HCV-attributable costs (p = 0.0167) over the entire follow-up period were significantly lower for patients treated with peginterferon alfa-2a plus ribavirin versus peginterferon alfa-2b plus ribavirin. Analysis of information from a health care claims database suggests that treating CHC with peginterferon alfa-2a plus ribavirin may improve treatment persistence and help reduce the health care costs imposed by CHC compared with treatment with peginterferon alfa-2b plus ribavirin.

    A 2-year-old boy presented with a recurrent strawberry-like reddish mass arising from the left caruncular region for 8 months. An incisional biopsy was performed elsewhere 2 months earlier, followed by an increase in size of mass, significant epiphora, and intermittent bleeding. On examination, exuberant exophytic gelatinous mass with multifocal origin was observed arising from inferior forniceal conjunctiva and caruncle. Clinical differential of multifocal conjunctival papilloma was kept, and topical interferon alfa-2b (INFα-2b) was started. No clinical reduction in mass or symptomatology was observed over 6 weeks. Excision biopsy with cryotherapy and subconjunctival injection of INFα-2b was performed over all foci. Conjunctival papilloma was confirmed on histopathology, and topical INFα-2b was continued in postoperative period for 3 months. At 14 months of follow-up, no recurrence, epiphora, or bleeding was noticed. We advocate a possible role of local INF therapy in managing and preventing recurrences of conjunctival papillomatosis.

    Full Text Available Aim: The initial therapy for superficial bladder carcinoma is the transurethral resection of the tumor. In spite of successful resections, there are 60-79% recurrence and 15% progression rates. Additional therapies are suggested for the treatment of superficial bladder carcinoma. We compared the efficacy of interferon alfa-2b monotherapy with interferon alfa-2b plus Bacillus Calmette Guerin (BCG combination therapy with urine interleukin (IL 2, 6 and 10 levels of patients with superficial bladder carcinoma. Material and Method: The patients who underwent TUR-BT for superficial bladder tumor (pathological staging Ta-T1 between 2004 and 2007 at our hospital included in this prospective study. Intravesical immunotherapy was administered once a week for 6 weeks and there after a month for 6 months, starting 4 weeks after TUR-BT. IL levels were measured. Results: IL-2, IL-6 and IL- 10 levels in urine samples were taken at 2nd and 4th hours of intravesical therapy. A statistically significant difference was observed between mean urine IL-2 levels of patients treated with IFN%u03B1-2b monotherapy and IFN%u03B1- 2b plus BCG combination both at 2nd and 4th hours. (p=0.05 In IFN%u03B1-2b plus BCG combination group, there was a statistical significant difference between stages regarding IL-2 and IL-6 levels (p=0.05. Among patients with G3 tumors, IL-2 levels were higher at 2 and 4 hours (p=0.05 but there was no significant difference in IL-6 and IL-10 levels in this group of patients regardless of intravesical therapy received (p=0.05. Discussion: IFN%u03B1-2b and BCG combination therapy is a reliable and effective therapy in the management of superficial bladder tumors.

    To evaluate topical interferon alfa-2b (IFN-alpha2b) for the treatment of recalcitrant ocular surface squamous neoplasia (OSSN). Prospective, noncomparative, interventional consecutive case series. Ten patients with recalcitrant OSSN were treated with topical IFN-alpha2b (1 million IU/ml) four times a day until clinical resolution of the lesion or until the lesion appeared nonresponsive-that is, treatment failure. Progress was assessed by clinical examination and photographic records, with a minimum follow-up of six months. Eight of 10 patients achieved clinical resolution from topical IFN-alpha2b treatment. One patient developed invasive squamous cell carcinoma and underwent exenteration. The other patient required further mitomycin C therapy to achieve clinical resolution. The mean duration to clinical resolution for the eight patients treated with IFN-alpha2b was 21.9 weeks (range six to 59 weeks). There have been no recurrences for any of the nine patients during follow-up (mean 55.0 weeks; range 26 to 84 weeks). Topical IFN-alpha2b is an important treatment modality for recalcitrant OSSN; it avoids the risks of further limbal stem cell destruction from other agents and surgical excision. If invasive disease is diagnosed at any stage, topical therapy is contraindicated, necessitating surgical excision.

    In this prospective, open-label, multicenter phase 1/2 dose escalation study, we used a next-generation, mono-pegylated interferon (IFN) α-2b isoform, ropeginterferon alfa-2b. The unique feature of ropeginterferon alfa-2b is a longer elimination half-life, which allows administration every 2 weeks. We present data from 51 polycythemia vera patients. The main goal was to define the maximum tolerated dose and to assess safety and efficacy. A dose range of 50 to 540 µg was tested without the appearance of dose-limiting toxicities. All drug-related adverse events were known toxicities associated with IFN-α. The cumulative overall response rate was 90%, comprising complete response in 47% and partial response in 43% of patients; the best individual molecular response level was a complete response in 21% of patients and partial response in 47%. Notably, we did not observe any correlation between the dose level and the response rate or response duration, suggesting that already low levels of ropeginterferon alfa-2b are sufficient to induce significant hematologic and molecular responses. These data suggest promising efficacy and safety of ropeginterferon alfa-2b and support the development of the drug in a randomized phase 3 clinical trial. The study was disclosed at www.clinicaltrials.gov as #NCT01193699 before including the first patient. PMID:26261238

    Patients with chronic hepatitis C virus (HCV) infection are frequently treated with a combination of pegylated interferon (peginterferon) and ribavirin. This study compared the efficacy and safety of peginterferon alfa-2a and peginterferon alfa-2b, each in combination with ribavirin. A total of 320 consecutive, treatment-naive, HCV RNA-positive patients with chronic hepatitis were randomly assigned to once-weekly peginterferon alfa-2a (180 microg, group A) or peginterferon alfa-2b (1.5 microg/kg, group B) plus ribavirin 1000 mg/day (body weight or=75 kg) for 48 weeks (genotype 1 or 4) or 24 weeks (genotype 2 or 3). The primary end point was sustained virological response (SVR) by intention-to-treat. More patients in group A than group B achieved an SVR (110/160 [68.8%] vs 87/160 [54.4%]; P = .008). Higher SVR rates were obtained in group A than group B among patients with genotype 1/4 (51/93 [54.8%] vs 37/93 [39.8%]; P = .04), with genotype 2/3 (59/67 [88.1%] vs 50/67 [74.6%]; P = .046), without cirrhosis (96/127 [75.6%] vs 75/134 [55.9%]; P = .005), and with baseline levels HCV RNA >500,000 IU/mL (58/84 [69%] vs 43/93 [46.2%]; P = .002). SVR rates in groups A and B were not statistically different among patients with baseline HCV RNA alfa-2a plus ribavirin produced a significantly higher SVR rate than peginterferon alfa-2b plus ribavirin.

    Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre......-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP......-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median...

    Interferon alfa and cytotoxic drugs have synergistic effects in patients with non-Hodgkin's lymphoma. In 1986, we designed a clinical trial to evaluate the benefit of concomitant administration of recombinant interferon alfa with a regimen containing doxorubicin in patients with follicular non-Hodgkin's lymphoma. The trial involved 242 patients with advanced low-grade follicular non-Hodgkin's lymphoma selected on the basis of clinical, radiographic, and biologic criteria. All patients were treated with a regimen consisting of cyclophosphamide, doxorubicin, teniposide, and prednisone (CHVP), given monthly for six cycles and then every two months for one year. After randomization, 123 patients also received interferon alfa-2b at a dosage of 5 million units three times weekly for 18 months. The remaining 119 patients received chemotherapy alone. As compared with the patients treated with CHVP only, the patients treated with CHVP plus interferon alfa had a higher overall rate of response (85 percent vs. 69 percent, P = 0.006), a longer median event-free survival (34 months vs. 19 months, P < 0.001), and a higher rate of survival at 3 years (86 percent vs. 69 percent, P = 0.02). Granulocyte toxicity was greater in the patients treated with CHVP plus interferon alfa than in those treated with CHVP alone. There were no treatment-related deaths. Interferon alfa had to be stopped because of toxic effects (fatigue and hepatitis) in 13 patients (11 percent). The addition of interferon alfa to a regimen containing doxorubicin increased the rate of response, event-free survival, and overall survival in patients with advanced follicular non-Hodgkin's lymphoma, without serious toxicity, although some patients were unable to tolerate the side effects.

    2015-01-01

    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.

    To examine the effects of interferon (IFN) therapy on clinical, biochemical, and histological features in patients with compensated hepatitis C virus (HCV)-related cirrhosis, we have conducted a randomized, controlled trial of IFN therapy versus observation. Eight centers included a total of 99 patients with biopsy-proven cirrhosis. IFN-alpha2b, 3 million units three times per week, or no antiviral therapy was given for 48 weeks. Twenty-three patients dropped out. End-of-treatment biochemical response was not observed in any of the 39 controls but was observed in 6 of the 47 treated patients (P <.02); sustained biochemical response was obtained in only 2 treated patients. Controls and treated patients did not significantly differ with regard to the changes in serum level of albumin, bilirubin, alpha-fetoprotein, in plasma prothrombin, in histological activity, or liver collagen content. During trial or follow-up (160 +/- 57 weeks), hepatocellular carcinoma developed in 9 controls and 5 treated patients (NS); decompensation of cirrhosis occurred in 5 controls and 7 treated patients. Seven controls and 10 treated patients died. In conclusion, in patients with compensated HCV-related cirrhosis, a 48-week course of IFN therapy is safe and is able to induce end-of-treatment biochemical response in a significant proportion of patients. However, a 48-week course of IFN therapy usually fails to achieve sustained response and, within the limit of this study, did not significantly improve the 3-year outcome. Therefore, a longer course of IFN therapy or combination therapy with ribavirin should be evaluated in patients with HCV-related cirrhosis.

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. 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.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusion 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.

Methods RNA was isolated from peripheral blood monocytes (PBMC from twenty treatment-naïve patients just before treatment (day 1 and at days 3, 6, 10, 13, 27, 42 and 70 days after treatment. Gene expression at each time was measured using Affymetrix microarrays and compared to that of day 1. Results The expression of many genes differed significantly (p ≤ 0.001 and changed at least 1.5-fold at days 3 (290 probes and 10 (255 probes, but the number dropped at days 6 (165 and 13 (142. Most genes continued to be up regulated throughout the trial period. A second group of genes, including CXCL10, CMKLR1 (chemokine receptor 1, TRAIL, IL1Rα and genes associated with complement and lipid metabolism, was transiently induced early in treatment. CDKN1C (cyclin kinase inhibitor 1 was induced early but repressed at later times. Genes induced at later times were mostly related to blood chemistry and oxygen transport. By week 10, 11 of the patients demonstrated a positive response to therapy, and the final sustained viral response (SVR was 35%. The levels of gene induction or decrease was very similar to that previously reported with Pegasys/ribavirin treatment. Conclusion The response to Pegintron/ribavirin was similar to that reported for Pegasys/ribavirin despite some differences in the amount administered. We did not detect major differences at the genomic level between patients responding to treatment or non-responders, perhaps because of limited power.

    Full Text Available OBJETIVO: Avaliar a concentração de alfa-tocoferol no colostro humano em condições de suplementação com cápsulas de vitamina A acrescidas de vitamina E sintética. MÉTODOS: Foram recrutadas para o estudo 30 parturientes saudáveis atendidas em uma maternidade pública. Após jejum noturno, foram coletadas amostras de sangue e de colostro (2 mL das parturientes. Após a primeira coleta, as mesmas receberam suplemento na forma de uma cápsula de palmitato de retinila (200000 UI ou 60 mg acrescido de vitamina E sintética (49,4 mg de dl-alfa-tocoferol. Após 24 horas da suplementação, foi realizada nova coleta de 2 mL de colostro, também em jejum. RESULTADOS: A concentração sérica de alfa-tocoferol foi de 1 042,9 ± 319,0 μg/dL. Os teores de alfa-tocoferol no colostro antes da suplementação foram de 1155,4 ± 811,0 μg/dL, vs. 1396,3 ± 862,2 μg/dL 24 horas depois da suplementação (P > 0,05.

    EURAMOS-1, an international randomized controlled trial, investigated maintenance therapy with pegylated interferon alfa-2b (IFN-α-2b) in patients whose osteosarcoma showed good histologic response (good response) to induction chemotherapy. At diagnosis, patients age ≤ 40 years with resectable high-grade osteosarcoma were registered. Eligibility after surgery for good response random assignment included ≥ two cycles of preoperative MAP (methotrexate, doxorubicin, and cisplatin), macroscopically complete surgery of primary tumor, < 10% viable tumor, and no disease progression. These patients were randomly assigned to four additional cycles MAP with or without IFN-α-2b (0.5 to 1.0 μg/kg per week subcutaneously, after chemotherapy until 2 years postregistration). Outcome measures were event-free survival (EFS; primary) and overall survival and toxicity (secondary). Good response was reported in 1,041 of 2,260 registered patients; 716 consented to random assignment (MAP, n = 359; MAP plus IFN-α-2b, n = 357), with baseline characteristics balanced by arm. A total of 271 of 357 started IFN-α-2b; 105 stopped early, and 38 continued to receive treatment at data freeze. Refusal and toxicity were the main reasons for never starting IFN-α-2b and for stopping prematurely, respectively. Median IFN-α-2b duration, if started, was 67 weeks. A total of 133 of 268 patients who started IFN-α-2b and provided toxicity information reported grade ≥ 3 toxicity during IFN-α-2b treatment. With median follow-up of 44 months, 3-year EFS for all 716 randomly assigned patients was 76% (95% CI, 72% to 79%); 174 EFS events were reported (MAP, n = 93; MAP plus IFN-α-2b, n = 81).

    Komarek, Tomas

    2014-01-01

    This note serves as a final report about CERN Summer Student Programme 2014 project. The beam halo is an undesired phenomenon for physics analyses on particle accelerators. It surrounds the beam core and constitutes an important part of background for signal measurements on some detectors, eg. in the forward region. In this study, the data from the ALFA detector were used, specifically from the run 191373 ($\\beta^*=90\\unit{m}$) and the run 213268 ($\\beta^*=1\\unit{km}$). Using the ROOT framework, a software for beam halo events selection was created and beam halo properties were examined. In the run 213268, excessive beam halo is suspected to be the reason for multiple beam scrapings that occurred. A kinematic reconstruction of beam halo particles is attempted in order to understand beam halo properties in the interaction point. Some further simulations are employed to find constraints for beam halo particles in order to survive in the accelerator for a longer time/many revolutions. This work represents a st...

    Full Text Available Abstract Background Gonadotrophins are routinely administered in assisted reproductive technology (ART treatment protocols. 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

  1. Implementation of Trigger Tiles for ALFA Simulation

    CERN Document Server

    Rehaag, Thomas Joseph

    2017-01-01

    The Absolute Luminosity For ATLAS (ALFA) experiment was designed to accurately measure the luminosity of the intersecting proton beams at the ATLAS interaction point [1]. However, the ALFA experiment has shifted its primary purpose from luminosity measurement to elastic and inelastic proton collisions. This change was the result of difficulty in fitting parameters in the region governed by Coulomb scattering. The operational principle for luminosity measurement with ALFA relied on detecting elastic proton collisions, so the detector is suited to its role in proton collision measurements. The ALFA detector consists of several sensitive components, including the main detector (MD), overlap detectors (ODs) and trigger tiles. A diagram of the ALFA detector is shown in Figure 1. The main detector is composed of layers of 0.5 × 0.5 mm2 cross section scintillating fibres with an active area of 0.48 × 0.48 mm2, which are directed diagonally across the detector with 64 fibres in each layer. The 20 total layers ar...

    Interferon alfa remains the central treatment for chronic hepatitis C virus (HCV) infection. Cases of cutaneous and mucous hyperpigmentations during interferon alfa treatment have been reported, but they are considered rare adverse effects. To study the clinical presentation and frequency of hyperpigmentation in patients receiving interferon alfa treatment for chronic HCV infection. Prospective, descriptive clinical trial. Monocentric study performed in the Departments of Hepatology and Dermatology of the University Hospital of Nice, Nice, France. Consecutive patients treated with pegylated interferon alfa-2b and ribavirin for chronic HCV infection. Demographic data and medical history were noted. A systematic clinical and dermoscopic examination of skin, nails, and mucous membranes was performed, and skin biopsies were performed if needed. Of 77 patients who were included, 16 (21%) presented with hyperpigmentation. Hyperpigmentation of the oral mucous membrane, acquired longitudinal melononychia, and hyperpigmentation of the face were each observed in 7 patients (9%). All patients with hyperpigmentation of the skin had skin type III or IV and worked outside without sun protection. The intensity of pigmentation was reported to decrease progressively when interferon treatment was discontinued. Most patients with hyperpigmentation of the oral mucosa also had melanonychia. However, patients with hyperpigmentation of the skin did not have mucosal or nail involvement, suggesting 2 distinct mechanisms. Secondary hyperpigmentation during interferon alfa treatment occurs as an adverse event in 21% of patients, especially in those with dark skin types who have unprotected sun exposure. Physicians should be aware of the adverse effects of interferon treatment and advise patients in the use of sun protection, especially patients with darker skin types.

    2017-01-01

    The ALFA_CTPIN module has been designed in response to increased internal processing time of the Central Trigger Processor (CTP) of the ATLAS experiment which resulted in reducing time left to the ALFA detector to deliver its own triggers to the CTP within specified latency. Accelerated extraction of ALFA triggers from encoded signals and the possibility to perform local triggers processing by this module allowed ALFA to contribute to global triggering of the ATLAS detector. A huge number of implemented scalers and flexibility in defining triggers processing criteria make also from this module a very attractive tool for in-depth analysis of properties of the LHC beam.

    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.

    Background. Anemia is one of the most challenging problems in clinical oncology due to its high prevalence among the patients with malignant diseases. The purposes of our study were: (1) to assess the potential of epoetin alfa therapy to prevent the decline in Hb concentrations that typically accompanies chemotherapy/ radiotherapy (ChT/RT) of the patients with rectal cancer; (2) to test the hypothesis that the use of epoetin alfa significantly reduces the transfusion requirements in the patients with rectal cancer treated with ChT/RT after surgery, and (3) to evaluate the safety profile of the administration of epoetin alfa in the clinical setting. Methods. Sixty patients who underwent surgery for rectal cancer were prospectively enrolled. Group A consisted of 39 patients with Hb concentrations ≤13 g/dl at the start of ChT/RT following surgery, and group B of 17 patients with Hb concentrations ≥13 g/dl at the start of ChT/RT following surgery, but whose Hb concentrations fell below 13 g/dl during the ChT/RT protocol. The starting dose of epoetin alfa in both groups was 10,000 IU subcutaneously (sc) three times a week (tiw). The following major parameters were evaluated: (1) change in Hb concentrations relative to the baseline as measured at 4-week intervals, (2) allogenic blood transfusion requirements in relation to Hb concentrations, and (3) incidence and severity of adverse events and their potential relationship to epoetin alfa administration. Results. The study protocol was completed in 56/60 patients. In group A, a statistically significant increase in Hb concentration (p<0.001) was observed after the first 4 weeks of epoetin alfa treatment compared to the baseline values, with the mean increase of Hb concentration of 1.97 g/dl ± 0.91 g/dl and Hb concentrations remained significantly increased through the whole study (p=0.0017). In group B, a continuous decrease in Hb concentrations was observed during the first weeks of therapy, reaching the level of

    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. Mean hemoglobin concentration (g/dL was 11.69 (95% CI, 11.53-11.86 6 months before the conversion, 12.25 (95% CI, 12.13-12.38 at conversion, and 11.88 (95% CI, 11.74-12.02 12 months after conversion to darbepoetin alfa Q2W.

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 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...

    2017-08-01

    Patients with resected stage II or III melanoma are at high risk of recurrence, with 5-year mortality rate of 40-60%. Adjuvant interferon-alfa has demonstrated a small RFS and OS benefit versus observation in this patient population. However, the adjuvant treatment landscape is evolving rapidly. Areas covered: This review aims to summarize the safety and efficacy profiles of adjuvant IFNα/PEG-IFNα, revisit the controversy surrounding its application, and reappraise its position in the rapidly changing treatment landscape of resected melanoma. A literature search using PubMed database was undertaken using search words melanoma, interferon-alfa, pegylated interferon-alfa, adjuvant therapy. Expert opinion: Currently, there is no international consensus regarding the optimal dosing schedule for adjuvant IFNα, but HD IFNα-2b remains the most widely used regimen. The AEs of HD IFNα-2b are substantial; however, toxicity management experience amassed over the past 2 decades has significantly improved safety. Many exciting studies are ongoing to examine the roles of immune checkpoint inhibitors and BRAF-targeted therapies in the adjuvant setting and will further delineate the role of adjuvant IFNα.

    La aparición de un nuevo consenso internacional en torno a las nociones de derechos humanos y democracia, como valores generalmente aceptados por la comunidad de naciones en su conjunto, y la afirmación de que el ser humano es titular de derechos propios, oponibles jurídicamente a todos los Estados, constituyen extraordinarias innovaciones que hacen que, a diferencia del Derecho internacional clásico, la persona no pueda seguir siendo considerada como un mero objeto del Derecho internacional.

Although there is an approved reversal agent for the direct thrombin inhibitor dabigatran, a specific reversal agent for the anti-factor Xa (FXa DOACs has yet to be licensed. Unlike the strategy to reverse the only oral direct thrombin inhibitor with idarucizumab, which is a humanized monoclonal antibody fragment, a different approach is necessary to design a single agent that can reverse multiple anti-FXa medications. Andexanet alfa is a FXa decoy designed to reverse all anticoagulants that act through this part of the coagulation cascade including anti-FXa DOACs, such as apixaban, edoxaban and rivaroxaban, and indirect FXa inhibitors such as low-molecular-weight heparins. This narrative reviews the development of andexanet alfa and explores its basic science, pharmacokinetics/pharmacodynamics, animal models, and human studies.

  2. Physics prospects with the ALFA and AFP detectors

    CERN Document Server

    Hamal, P; The ATLAS collaboration

    2013-01-01

    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 $\\pm${240}~m 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 $10^{-3} \\text{GeV}^2$ - 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 cosmic ray physicists and to provide absolute measurement of luminosity which includ...

  10. Alternative method for quantification of alfa-amylase activity

    Directory of Open Access Journals (Sweden)

    DF. Farias

    Full Text Available A modification of the sensitive agar diffusion method was developed for macro-scale determination of alfa-amylase. The proposed modifications lower costs with the utilisation of starch as substrate and agar as supporting medium. Thus, a standard curve was built using alfa-amylase solution from Aspergillus oryzae, with concentrations ranging from 2.4 to 7,500 U.mL-1. Clear radial diffusion zones were measured after 4 hours of incubation at 20 °C. A linear relationship between the logarithm of enzyme activities and the area of clear zones was obtained. The method was validated by testing α-amylase from barley at the concentrations of 2.4; 60; 300 and 1,500 U.mL-1. The proposed method turned out to be simpler, faster, less expensive and able to determine on a macro-scale α-amylase over a wide range (2.4 to 7,500 U.mL-1 in scientific investigation as well as in teaching laboratory activities.

    2013-04-01

    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.

    A 57-year-old Italian man was admitted to our Hospital for investigation of a progressively raising alfa-fetoprotein (AFP) on the background of chronic hepatitis B infection. At abdominal imaging,liver morphology was suspected for advanced fibrosis but without any focal lesion. Clinical and ultrasonographic examinations were negative for testicular masses. When the patient was screened for gastroesophageal varices, upper intestinal endoscopy did not show signs of portal hypertension, while it revealed a gastric lesion which was histologically characterized as hepatoid adenocarcinoma of the stomach (HAS), with strong immunohistochemical positivity for AFP. The patient underwent subtotal gastrectomy and AFP fell within the normal range. This is a very rare case in which AFP-producing gastric cancer (AFPPGC), in the form of HAS, presented in a patient with chronic liver disease. Physicians should be particularly aware of AFPPGC when following patients with liver disorders due to the common use of AFP in this setting.

    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.

    Pfeiffer, Felix-Fabian; Stenzel, H

    2010-01-01

    ALFA (Absolute Luminosity for ATLAS) is a scintillating fiber detector for the determination of the absolute luminosity. ALFA con- sists of eight Roman Pots, four on each side of ATLAS at a distance of 240 m. Each detector is made of scintillating fibers with quadratic cross section, glued in UV geometry on ten double sided layers. The detectors are mounted in moveable Roman Pots and can approach the LHC beam up to 1.5 mm, to determine the luminosity from the differential t spectrum of elastically scattered protons using the optical theorem. This is done in special LHC calibration runs with large β ∗ , special focusing and low instant luminosity. The results of ALFA are needed for the calibration of ATLAS luminosity monitors like LUCID. This diploma thesis deals with the simulation of ALFA and the most recent testbeam campaign. A special focus is put on the comparison of results from simulation and testbeam.

    Full Text Available Within the present paper, we propose to review some of the main aspects documented by the academic research so far with regard to the online purchasing behaviour in the B2B online environment (more specifically, in the case of the small and medium-sized companies. Preliminary conclusions reveal that, at least in the case studies, the dominant feature is that the geographic delimitation creates a potential obstacle when it comes to applying a general principle governing the small and medium-sized enterprises. Despite this, we consider that some theoretical elements can be acknowledged, elements from which future research can start to develop theories and hypothesis aimed at better explaining the phenomenon. Furthermore, the fact that the studies are rarely involving the same sector, makes it impossible to generalise the process.

    Mytych, Daniel T; La, Stephon; Barger, Troy; Ferbas, John; Swanson, Steven J

    2009-02-20

    A surface plasmon resonance (SPR)-based biosensor immunoassay was developed and validated using the Biacore 3000 instrument to detect, semi-quantitate, and characterize serum antibodies against darbepoetin alfa (Aranesp) and epoetin alfa (EPOGEN). In this sensitive, dual-flow cell assay, epoetin alfa and darbepoetin alfa are covalently immobilized onto consecutive flow cells of a carboxymethyl dextran-coated sensor chip. Diluted human serum samples are injected sequentially over both surfaces. The binding of serum antibodies to the immobilized proteins are detected and recorded in real time based on the principles of SPR. Furthermore, antibody binding is confirmed with a secondary anti-human immunoglobulin antibody. Positive samples are further characterized to determine the relative concentration of the antibodies using an affinity-purified, rabbit anti-epoetin alfa antibody as a reference control. The assay can detect 80ng/ml and 100ng/ml of antibody to epoetin alfa and darbepoetin alfa, respectively. The dynamic range of the assay is from 0.078microg/ml to 10microg/ml using a rabbit antibody with demonstrated accuracy and intra- and inter-assay precision. Approximately 80 serum samples can be analyzed on each sensor chip while maintaining a stable baseline and consistent immunological reactivity. The analysis of serum samples from subjects administered with epoetin alfa or darbepoetin alfa provided evidence that the assay can detect varying concentrations of antibodies of different off rates, isotypes, and IgG subclasses.

    CERN Document Server

    Fabbri, L; The ATLAS collaboration

    2009-01-01

    In order to determine the experimental cross sections for the observed physics processes, an estimation of the absolute luminosity is needed. In fact a careful study of “well known” processes will be one of the first steps of the LHC experiments as it can provide possible signatures of new physics which consist in deviations with respect to the Standard Model (SM) predictions. The methodologies for luminosity monitoring and total cross section estimation at the LHC will be reviewed in this talk along with the dedicated detectors of the ATLAS experiment. ATLAS will make extensive usage of the detectors in the forward region each one with a different task: LUCID (LUminosity measurement using Cherenkov Integrating Detector) is a system of 40 (2 x 20) Cherenkov tubes, surrounding the beam pipe at about 17 m from the interaction region. It will be able to monitor the collision-by-collision luminosity by detecting and counting the number of charged particles coming from the impact point. ALFA (Absolute Luminosi...

  7. Home infusion program for Fabry disease: experience with agalsidase alfa in Argentina

    Directory of Open Access Journals (Sweden)

    Isaac Kisinovsky

    2013-02-01

    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.

    2015-01-01

    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.

    The long-acting opioid methadone displays considerable unexplained interindividual pharmacokinetic variability. Methadone metabolism clinically occurs primarily by N-demethylation to 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), catalyzed predominantly by CYP2B6. Retrospective studies suggest that the common allele variant CYP2B6*6 may influence methadone plasma concentrations. The catalytic activity of CYP2B6.6, encoded by CYP2B6*6, is highly substrate-dependent. This investigation compared methadone N-demethylation by CYP2B6.6 with that by wild-type CYP2B6.1. Methadone enantiomer and racemate N-demethylation by recombinant-expressed CYP2B6.6 and CYP2B6.1 was determined. At substrate concentrations (0.25–2 µM) approximating plasma concentrations occurring clinically, rates of methadone enantiomer N-demethylation by CYP2B6.6, incubated individually or as the racemate, were one-third to one-fourth those by CYP2B6.1. For methadone individual enantiomers and metabolism by CYP2B6.6 compared with CYP2B6.1, Vmax was diminished, Ks was greater and the in vitro intrinsic clearance was diminished 5- to 6-fold. The intrinsic clearance for R- and S-EDDP formation from racemic methadone was diminished approximately 6-fold and 3-fold for R- and S-methadone, respectively. Both CYP2B6.6 and CYP2B6.1 showed similar stereoselectivity (S>R-methadone). Human liver microsomes with diminished CYP2B6 content due to a CYP2B6*6 allele had lower rates of methadone N-demethylation. Results show that methadone N-demethylation catalyzed by CYP2B6.6, the CYP2B6 variant encoded by the CYP2B6*6 polymorphism, is catalytically deficient compared with wild-type CYP2B6.1. Diminished methadone N-demethylation by CYP2B6.6 may provide a mechanistic explanation for clinical observations of altered methadone disposition in individuals carrying the CYP2B6*6 polymorphism.

    Reports from the World Health Organization have suggested that counterfeit medicines pose a serious problem in developing countries. An investigation of anti-erythropoietin antibody-mediated pure red cell aplasia in Thailand found evidence of drug smuggling, which may have serious safety implications. This study assessed the authenticity and quality of epoetin alfa samples in Thailand. Samples of epoetin alfa-prefilled syringes were collected from the pharmacies at 2 major hospitals (62 samples), 8 retail pharmacies (41 samples), and Thai authorities (30 samples confiscated from smugglers at 2 airports, and 6 samples from a condominium used by smugglers). These samples were tested against the European Union Pharmacopeia specifications for aggregate content in epoetins of packaging components (eg, batch number, expiration date, appearance, letter size), and company's confidential features (eg, nature of the ink, type and quality of the paper, other covered features) were also investigated. The main outcome measures were protein aggregate content, determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis and Western blotting; and isoform distribution, assessed by isoelectric focusing and Western blotting. Epoetin alfa samples obtained from the company's cold-chain and authorized distribution channels met all quality standards, as did all epoetin alfa samples obtained from the hospital pharmacies. However, evidence showed that some samples were being smuggled or sold illegally through certain unauthorized retail pharmacies. The epoetin alfa samples obtained from both airports and the condominium were stored improperly at room temperature. Aggregate levels exceeded the specification of packaging were found to be authentic. This investigation found evidence that some epoetin alfa samples were smuggled into Thailand without proper cold chain, contained high levels of protein aggregates, and were sold illegally through certain retail pharmacies.

    Inflammatory cytokines may influence both labile anger and depression. Both psychiatric conditions can occur during interferon alfa-based treatments. Evidence also indicates a central nervous system role for tumor necrosis factor alpha (TNF-alpha), whose expression may be increased by interferon alfa. A polymorphism in the promoter region of TNF-alpha has been associated with various inflammatory illnesses. We therefore hypothesized that this TNF-alpha polymorphism would influence susceptibility to psychiatric symptoms during interferon alfa therapy. One hundred five patients with hepatitis C, initially without active major depression (major depressive disorder), were treated with interferon alfa and then prospectively monitored using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, the Beck Depression Inventory II, the Anger Irritability and Assault Questionnaire, and circulating TNF-alpha levels. The A-308G polymorphism (rs1800629) was determined using the 5'-nuclease assay. Repeated-measure mixed-effect analyses compared changes in symptoms over time. Beck Depression Inventory II score increased during interferon alfa therapy (F = 6.2; P depression incidence (chi = 0.0; P = 0.99) or increased Beck Depression Inventory II (F = 1.2; P = 0.31). Labile anger was not predicted by the serotonin transporter polymorphism (F = 0.8; P = 0.59). During treatment with an exogenous cytokine, vulnerability to worsening labile anger-distinct from major depression-is associated with genetic variability in TNF-alpha. This has implications both for patients being treated with interferon alfa and our understanding of genetic vulnerability for different subtypes of dysphoric and mood disorders.

    Full Text Available En carcinomas mamarios murinos (C4-HD y en células de cáncer de mama humano (T47D observamos que el progestágeno sintético, acetato de medroxiprogesterona (MPA, induce la activación del receptor de estrógenos alfa (REa y su asociación nuclear con el receptor de progesterona (RP. 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.

    Full text: Tumor hypoxia, particularly in anemia, increases the risk of distant metastases and decreases survival. However, the benefits of stimulating erythropoiesis to supraphysiological levels are unclear. This study examines the effect of darbepoetin alfa (DEPA) on tumor oxygenation and the response to therapeutic radiation (XRT) in rats with initially normal hematocrit. R3230 adenocarcinoma was transplanted into the flank of female Fisher 344 rats. Starting on Day 4 post transplant, the rats received DEPA 3 μg/kg or normal saline sc tiw. At 3 weeks post transplant, pO2 was measured and the tumor excised, or the tumor was irradiated. pO2 was determined using an optical microprobe. In histologic studies, rats were injected with pimonidazole prior to sacrifice, and the tumors excised and stained with an antibody to pimonidazole (PIMO). Extent/intensity of staining was assessed by 3 observers and averaged to yield an IHC score. Rats ± DEPA with tumors 7 -12mm diameter were randomised to receive 32 Gy in 4 bid doses or sham irradiation. Tumor diameters in the 4 groups (±DEPA x ±XRT, total n=41) were measured by calipers. Failure was defined by the tumor reaching 15mm in diameter and used to generate Kaplan-Meier curves. Hematocrit at transplant averaged 45% (n=104) versus 67% in the DEPA-treated rats (n=18, p<0.0001) and 44% in the control animals (n=21.) Median pO2 in the DEPA-treated rats vs. controls did not differ significantly (17 vs. 13 mm Hg, p=0.10.) However, the fraction of tumor pO2 measurements <10mm Hg in the DEPA-treated rats was lower (21% vs. 37%, p=0.046.) IHC score was also less in the DEPA group (p=0.03.) XRT significantly improved failure-free survival (p<0.0001.) While the addition of DEPA to either the XRT or control groups did not significantly increase survival, the trend in both cases favored the DEPA-treated groups. In this tumor, treatment with DEPA improves oxygenation. However, no significant enhancement in radioesponsiveness by DEPA

    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.

    Alfa leaves are important renewable raw materials in Tunisia where they are used basically in handcrafts and paper industry. Sumac is also an abundant species in Tunisia known for its high tannin content and is basically used in traditional medicine. To valorize these natural resources, we studied, for the first time, the possibility of making insulating panels based on alfa fibres and sumac tannins based adhesive. Firstly, alfa leaves were treated with an alkali solution as it is one of the standard procedures commonly used in the paper industry to extract cellulosic fibres. Mercerization effects were studied by characterizing fibres thermal properties and fibres surface morphology. Secondly, the sumac tannin based resin was formulated and characterized. Finally, the insulating panel was elaborated and characterized by determining its thermal conductivity. The thermal gravimetric analysis results show improvement in the thermal stability of fibres after alkali treatment. Environmental Scanning Electron Microscopy showed changes on treated alfa surface which could promote the fibre-matrix adhesion. The reactivity of sumac tannins to formaldehyde test (Stiasny number) showed the possible use of sumac tannins in wood adhesive formulation. Thermomechanical analysis and strength analysis of sumac tannin/hexamin based resin highlighted acceptable bonding properties. The thermal conductivity measurement showed an average value equal to 0.110 W/m K.

    Alexander, Sherri L; Ernst, Frank R

    2006-04-01

    Drotrecogin alfa (activated) has been approved by the United States Food and Drug Administration for treatment of patients at high risk of death from severe sepsis. Severe sepsis is common, and its occurrence increases dramatically with age. Clinical use data, however, suggest that drotrecogin alfa (activated) may be underused in older patients, possibly due to concern over the drug's anticoagulant effects and perceived high cost. In addition, clinicians often treat older patients less aggressively than younger patients. We reviewed a subgroup analysis of patients aged 75 years and older from a large clinical trial evaluating efficacy and safety of drotrecogin alfa (activated), as well as cost-effectiveness data from real-world clinical use of the drug in older patients. We also explored ethical dilemmas of treating older patients with sepsis. Drotrecogin alfa (activated) is safe, effective, and cost-effective in older patients with severe sepsis and should be considered for elderly intensive care patients who are high risk of death and who have no contraindications to treatment.

There are three commercially available enzyme replacement therapy (ERT products for the treatment of GD type 1 (GD1: imiglucerase, velaglucerase alfa, and taliglucerase alfa. Imiglucerase and velaglucerase alfa are produced in different mammalian cell systems; imiglucerase requires postproduction deglycosylation to expose terminal α-mannose residues, which are required for mannose receptor-mediated uptake by target macrophages. These steps are critical to the success of ERT for the treatment of visceral and hematologic manifestations of GD. Taliglucerase alfa is the first US Food and Drug Administration-approved plant-cell-expressed recombinant human protein, using carrot root cell cultures. Furthermore, it does not require postproduction glycosidic modifications. It is indicated for treatment of adults with GD1 in the US, Israel, Australia, Canada, Chile, Brazil, and other countries, and it is additionally approved for the treatment of pediatric patients in the US, Australia, and Canada and for the treatment of hematologic manifestations in pediatric patients with Type 3 GD in Canada and other countries. Our review focuses on the role of taliglucerase alfa in the pediatric population. A literature search through PubMed (from 1995 up till November 2016 of English language articles was performed with the following terms: Gaucher disease, lysosomal storage disease, taliglucerase. Secondary and tertiary references were obtained by reviewing

    Full Text Available O objetivo principal deste artigo foi identificar conceitos de valores humanos em publicações científicas sobre empreendedorismo. Não há um único conceito de valores humanos, gerando diversas abordagens e aplicações do termo em estudos sobre empreendedorismo. Para identificar diferenças conceituais e aplicações práticas, optou-se por realizar uma análise de conteúdo em um portfólio de artigos selecionados em bases de dados. O principal critério de seleção das publicações foi aderência ao tema. Os resultados mostram que valores podem ser definidos como: critérios de julgamento da realidade; aspectos abstratos, cognitivos e afetivos ou características determinantes da personalidade e do comportamento de empreendedores. Valores influenciam a sobrevivência do indivíduo, o crescimento do empreendimento e podem nivelar a congruência do empreendedor e seu propósito de empreendimento com os critérios de convivência social. Ainda foram discriminados resultados de estudos aplicados com vistas a destacar evidências de contribuições práticas de pesquisas sobre valores humanos em empreendedorismo. Futuras investigações para aprofundar e replicar as análises realizadas neste estudo podem contribuir com a formação de empreendedores, a realização de diagnóstico empresarial e com avanços para a consolidação um modelo de desenvolvimento de empresas baseado em valores humanos.

    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.

Por otro lado, superar los obstáculos al logro de la aspiración del desarrollo humano sostenible, entre los que sobresale la ausencia de mecanismos eficaces de distribución del ingreso y la significativa cantidad de seres humanos sumidos en la pobreza y las privaciones.Estas dos dimensiones del desarrollo regional se encuentran estrechamente entrelazadas y mutuamente condicionadas. Una distribución más equitativa del ingreso contribuye a elevar la movilidad social, el acceso a la educación, el aumento de la productividad y la estabilidad, aspectos esenciales para acrecentar la capacidad competitiva y para lograr una inserción de calidad en el contexto internacional. Una estrategia de integración en el contexto internacional, sustentada en las fortalezas nacionales, en la identidad cultural y en el capital humano, posibilita la sostenibilidad y la distribución de los beneficios entre los diversos estratos de la sociedad.

    We report a detailed study of the thermodynamic properties of the conventional phonon-mediated superconductors YPd2B2C, YPt2B2C and LaPt2B2C. Our calculations conducted within the framework of the Migdal-Eliashberg formalism show that the experimental values of the critical temperature cannot be properly reproduced using commonly accepted value of Coulomb pseudopotential. Moreover, we proved that the values of universal ratios of conventional superconductivity appearing in the Bardeen-Copper-Schrieffer (BCS) theory are inconsistent with our results obtained from the investigated borocarbides. The observed differences are connected with the strong/medium-coupling and retardation effects existing in the studied systems.

    Cytochrome P450 2B6 (CYP2B6) is an important drug-metabolizing enzyme and is expressed in liver. Although human CYP2B6 variants account for variable enzyme properties among individuals and populations, CYP2B6 genetic variants have not been investigated in cynomolgus macaques, widely used in drug metabolism studies. CYP2B6 was resequenced in 120 cynomolgus macaques and 23 rhesus macaques by direct sequencing. Twenty-three non-synonymous variants were found, of which 12 and 3 were unique to cynomolgus macaques and rhesus macaques, respectively. By functional characterization using the 14 variant proteins, 8 variants (V114I, R253C, M435I, V459M, L465P, C475S, R487C, and R487H) showed different rate (>1.5-fold) of testosterone 16β-hydroxylation to wild type. However, the four variants (M435I, L465P, C475S, and R487H) were analyzed in liver microsomes, and the catalytic rates were not substantially different from wild type. Macaque CYP2B6 was polymorphic, and the genotype could partly account for variable enzyme activities of macaque CYP2B6. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Luo, Jinping; McGinnis, Lynda K; Carlton, Carol; Beggs, Hilary E; Kinsey, William H

    2014-08-01

    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.

  18. A Study of Diffractive Scattering with the ATLAS and ALFA Experiment

    CERN Document Server

    AUTHOR|(CDS)2097773

    This thesis presents a study of diffractive scattering of high-energy protons. Hadronic diffraction is not well-understood and many alternative approaches exist. The Monte Carlo event generator Pythia 8 follows a Pomeron-based approach, where the invariant mass of the diffractive system and the squared momentum transfer $t$ of the system is set up according to a phenomenological Pomeron flux parameterization, which is parameterized by the super-critical Pomeron trajectory, $\\alpha(t) = 1 + \\varepsilon + \\alpha' t$, where the intercept parameter $\\varepsilon$ and the slope parameter $\\alpha'$ can be tuned by the user. A fast detector response simulation of the ALFA and ATLAS detectors has been developed in the Rivet toolkit for the purposes of this thesis. The developed simulation framework is able to handle the beam transport of diffractively scattered protons as well as impose the kinematic acceptance of the ALFA detector which was found to be approximately $\\xi \\lesssim 0.22$, with a pseudorapidity coverag...

El presente artículo tiene el propósito de mostrar esta interdependencia a partir del análisis crítico sobre su realización en dos campos políticos[1]: el comunitario y el estatal. El campo político comunitario teje articulaciones entre una cosmovisión originada en los pueblos indígenas, las reivindicaciones de grupos ciudadanos por la exigibilidad de los derechos humanos, y la doctrina social de la Iglesia que vela por el bien común. El campo político estatal se expresa en el impulso de un nuevo constitucionalismo basado en los derechos y en políticas nacionales de desarrollo para el Vivir Bien / Buen Vivir. [1] Siguiendo a Bourdieu, reconocemos que el campo político articula un nivel de acción ideológica y estratégica relacionada con la hegemonía del poder, otro institucional en el que se identifican los actores políticos, y un tercero en el que se definen los principios y normas.

    Two recombinant enzymes (agalsidase alfa 0.2 mg/kg/every other week and agalsidase beta 1.0 mg/kg/every other week) have been registered for the treatment of Fabry disease (FD), at equal high costs. An independent international initiative compared clinical and biochemical outcomes of the two enzymes. In this multicentre retrospective cohort study, clinical event rate, left ventricular mass index (LVMI), estimated glomerular filtration rate (eGFR), antibody formation and globotriaosylsphingosine (lysoGb3) levels were compared between patients with FD treated with agalsidase alfa and beta at their registered dose after correction for phenotype and sex. 387 patients (192 women) were included, 248 patients received agalsidase alfa. Mean age at start of enzyme replacement therapy was 46 (±15) years. Propensity score matched analysis revealed a similar event rate for both enzymes (HR 0.96, P=0.87). The decrease in plasma lysoGb3 was more robust following treatment with agalsidase beta, specifically in men with classical FD (β: -18 nmol/L, Pbeta (OR 2.8, P=0.04). LVMI decreased in a higher proportion following the first year of agalsidase beta treatment (OR 2.27, P=0.03), while eGFR slopes were similar. Treatment with agalsidase beta at higher dose compared with agalsidase alfa does not result in a difference in clinical events, which occurred especially in those with more advanced disease. A greater biochemical response, also in the presence of antibodies, and better reduction in left ventricular mass was observed with agalsidase beta. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    AlfaMC is a Monte Carlo simulation code for the transport of alpha particles. This code is based on the Continuous Slowing Down Approximation and uses the NIST/ASTAR stopping-power database. The code uses a powerful geometrical package, which allows coding of complex geometries. A flexible histogramming package is used as well, which greatly eases the scoring of results. The code is tailored for microdosimetric applications in which speed is a key factor. Comparison with the SRIM code is made for deposited energy in thin layers and range for air, mylar, aluminum and gold. The general agreement between the two codes is good for beam energies between 1 and 12 MeV. -- Highlights: • AlfaMC is a Monte Carlo program for fast alpha particle transport in matter. • The model is accurate within a few percent in the energy range of 1–12 MeV. • AlfaMC uses a combinatorial geometry package allowing the modeling of complex bodies.

  9. Preparation And Properties Of Bionanocomposite Films Reinforced With Nanocellulose Isolated From Moroccan Alfa Fibres

    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.

  10. Lithium insertion in nanostructured TiO(2)(B) architectures.

    Dylla, Anthony G; Henkelman, Graeme; Stevenson, Keith J

    2013-05-21

    Electric vehicles and grid storage devices have potentialto become feasible alternatives to current technology, but only if scientists can develop energy storage materials that offer high capacity and high rate capabilities. Chemists have studied anatase, rutile, brookite and TiO2(B) (bronze) in both bulk and nanostructured forms as potential Li-ion battery anodes. In most cases, the specific capacity and rate of lithiation and delithiation increases as the materials are nanostructured. Scientists have explained these enhancements in terms of higher surface areas, shorter Li(+) diffusion paths and different surface energies for nanostructured materials allowing for more facile lithiation and delithiation. Of the most studied polymorphs, nanostructured TiO2(B) has the highest capacity with promising high rate capabilities. TiO2(B) is able to accommodate 1 Li(+) per Ti, giving a capacity of 335 mAh/g for nanotubular and nanoparticulate TiO2(B). The TiO2(B) polymorph, discovered in 1980 by Marchand and co-workers, has been the focus of many recent studies regarding high power and high capacity anode materials with potential applications for electric vehicles and grid storage. This is due to the material's stability over multiple cycles, safer lithiation potential relative to graphite, reasonable capacity, high rate capability, nontoxicity, and low cost (Bruce, P. G.; Scrosati, B.; Tarascon, J.-M. Nanomaterials for Rechargeable Lithium Batteries. Angew. Chem., Int. Ed.2008, 47, 2930-2946). One of the most interesting properties of TiO2(B) is that both bulk and nanostructured forms lithiate and delithiate through a surface redox or pseudocapacitive charging mechanism, giving rise to stable high rate charge/discharge capabilities in the case of nanostructured TiO2(B). When other polymorphs of TiO2 are nanostructured, they still mainly intercalate lithium through a bulk diffusion-controlled mechanism. TiO2(B) has a unique open crystal structure and low energy Li

    The class 2b-3 truck market covers a wide range of commercial truck applications across a half-million vehicle sales annually. This report collected public information and stakeholder input to assess the opportunity for electrification in this market. Although class 2b-3 pickup truck and van bodies are very similar to personal light vehicles, their functional requirements are quite different due to the demands of the commercial market. These demands vary by application and often vary from day to day for a single application. Fleet customers purchase these vehicles to perform a particular job for their business and are concerned about the overall cost of doing that job. Therefore, the vehicles must meet the job requirements cost effectively. Customers also are sensitive to initial cost. Electrification offers the potential to reduce vehicle operating costs and possibly improve vehicle functionality. However, the current market for class 2b-3 electrified trucks is very small, and the trucks are costly. Increased production volumes are key to cost reductions and may be assisted by sharing components with larger or smaller truck classes. Expanding demand is also crucial and stakeholders identified several niche markets with duty cycles that are likely well-suited to electrified class 2b-3 trucks. To expand beyond these niches, class 2b-3 electric solutions must be robust, flexible, and adaptable in order to cover a wide range of vocations, applications, and duty cycles.

  12. Review of benchmark tests on JENDL-2B library

    1982-01-01

    JENDL-2B is a mixed library consisting of JENDL-2 for the most important nuclides, i.e., 235 U, 238 U, 239 Pu, 240 Pu, 241 Pu, Cr, Fe and Ni and of JENDL-1 for other nuclides. Complete reevaluation work was made for these eight nuclides. The simultaneous evaluation method was adopted in the evaluation for the five heavy nuclides. The resonance structure was carefully studied for the structural materials in the unresolved resonance region up to several MeV. Benchmark tests have been made on JENDL-2B. Various core center characteristics were tested with one-dimensional model for total of 27 assemblies. Satisfactory results were obtained as a whole. The results of spectrum indices, however, suggested some inconsistent spectrum prediction. Moreover, the reactivity worths were overestimated for most of materials, and apparent C/E discrepancies were observed between the Pu and U cores. Applicability of JENDL-2B was further tested to more sophisticated problems for MOZART and ZPPR-3 assemblies. The reaction rate distributions were better predicted with JENDL-2B than with JENDL-1. The positive sodium void reactivity worth was much overestimated with JENDL-2B due to too large moderation components. The control rod worths were well predicted in MOZART, but were considerably underpredicted in ZPPR-3. (author)

Utilizando anotações de observações do desenvolvimento de seus filhos, especialmente de seu filho mais velho William Erasmus (Doddy, Darwin descreve e estuda, a partir de seu enfoque naturalista, o filhote humano, narrando os primeiros indicativos comportamentais de emoções tais como raiva e medo, curiosidade e senso moral, o brincar e o prazer envolvido nesta atividade, a capacidade de imitação e os primeiros indícios daquilo que hoje conhecemos como "teoria da mente". Colocando-se questões sobre as capacidades do bebê, como eles aprendem e como se comunicam e levantando hipóteses sobre possíveis significados de certos comportamentos, questões ainda hoje fundamentais para o estudo do desenvolvimento humano, Darwin mostra-se também um pioneiro no estudo do bebê e da criança pequena, numa época na qual as capacidades dos bebês eram extremamente subestimadas e desconsideradas.

  15. ORM-Based Semantics of B2B Transactions

    Balsters, H.; van Blommestein, F.

    After widespread implementation of Enterprise Resource Planning and Personal Information Management, the next wave in the application of ICT is headed towards business to business (B2B) communication. B2B has a number of specific aspects, one of them being negotiation. This aspect has been largely neglected by present implementations of standard EDI- or XML-messaging and by B2B webservice implementations. In this paper a precise model is given of the negotiation process. The requirements of a potential Buyer and the offer of a potential Seller are matched and, if the negotiation is successful, a contract is concluded. The negotiation process model is represented in ORM, extended with dynamic constraints. Our model may be implemented in the databases of the trading partners and in message- or service definitions.

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.

  13. Human UDP-Glucuronosyltransferase 2B4 and 2B7 Are Responsible for Naftopidil Glucuronidation in Vitro

    Directory of Open Access Journals (Sweden)

    Xia-Wen Liu

    2018-01-01

    Full Text Available Naftopidil (NAF is widely used for the treatment of benign prostatic hyperplasia and prevention of prostate cancer in elderly men. These patients receive a combination of drugs, which involves high risk for drug–drug interaction. NAF exhibits superior efficacy but must be administered at a much higher dosage than other therapeutic drugs. We previously showed that extensive glucuronidation of NAF enantiomers caused poor bioavailability. However, the metabolic pathway and mechanism of action of NAF enantiomer remain to be elucidated. The present study was performed to identify the human UDP-glucuronosyltransferases (UGTs responsible for the glucuronidation of NAF enantiomers and to investigate the potential inhibition of UGT activity by NAF. The major metabolic sites examined were liver and kidney, which were compared with intestine. Screening of 12 recombinant UGTs showed that UGT2B7 primarily contributed to the metabolism of both enantiomers. Moreover, enzyme kinetics for R(+-NAF, UGT2B7 (mean Km, 21 μM; mean Vmax, 1043 pmol/min/mg showed significantly higher activity than observed for UGT2B4 and UGT1A9. UGT2B4 (mean Km, 55 μM; mean Vmax, 1976 pmol/min/mg and UGT2B7 (mean Km, 38 μM; mean Vmax, 1331 pmol/min/mg showed significantly higher catalysis of glucuronidation of S(--NAF than UGT1A9. In human liver microsomes, R(+-NAF and S(--NAF also inhibited UGT1A9: mean Ki values for R(+-NAF and S(--NAF were 10.0 μM and 11.5 μM, respectively. These data indicate that UGT2B7 was the principal enzyme mediating glucuronidation of R(+-NAF and S(--NAF. UGT2B4 plays the key role in the stereoselective metabolism of NAF enantiomers. R(+-NAF and S(--NAF may inhibit UGT1A9. Understanding the metabolism of NAF enantiomers, especially their interactions with metabolic enzymes, will help to elucidate potential drug–drug interactions and to optimize the administration of this medicine.

    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 ).

    2000-12-01

    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.

    Globotriaosylceramide concentrations were assessed as potential predictors of change from baseline after 12 months by estimated glomerular filtration rate and left-ventricular mass index using pooled data from three randomized, placebo-controlled agalsidase alfa trials and open-label extensions of patients with Fabry disease. Males (aged 18 years or older) with Fabry disease received agalsidase alfa (0.2 mg/kg every other week for 12 months). A backward-elimination approach evaluated potential predictors (baseline estimated glomerular filtration rate and left-ventricular mass index; age at first dose; baseline and change from baseline at 12 months of globotriaosylceramide (urine, plasma); urine protein excretion; and systolic and diastolic blood pressure). Subgroups included patients randomized to placebo or agalsidase alfa (double-blind phase), then to agalsidase alfa (open-label extensions; placebo→agalsidase alfa or agalsidase alfa→agalsidase alfa, respectively) and stage 2/3 chronic kidney disease patients. Baseline estimated glomerular filtration rate, age at first dose, baseline urine globotriaosylceramide excretion, and baseline and change from baseline urine protein excretion significantly predicted change from baseline estimated glomerular filtration rate in the analysis population (N = 73; all P<0.05), although not in all subgroups. Change from baseline urine and plasma globotriaosylceramide (baseline and change from baseline) concentrations did not predict change from baseline estimated glomerular filtration rate. No predictors of left-ventricular mass index were significant. Changes in globotriaosylceramide concentrations do not appear to be useful biomarkers for prediction of Fabry disease-related changes in estimated glomerular filtration rate or left-ventricular mass index.

  7. The ISS 2B PVTCS Ammonia Leak: An Operational History

    Science.gov (United States)

    Vareha, Anthony

    2014-01-01

    In 2006, the Photovoltaic Thermal Control System (PVTCS) for the International Space Station's 2B power channel began leaking ammonia at a rate of approximately 1.5lbm/year (out of a starting approximately 53lbm system ammonia mass). Initially, the operations strategy was "feed the leak," a strategy successfully put into action via Extra Vehicular Activity during the STS-134 mission. During this mission the system was topped off with ammonia piped over from a separate thermal control system. This recharge was to have allowed for continued power channel operation into 2014 or 2015, at which point another EVA would have been required. Without these periodic EVAs to refill the 2B coolant system, the channel would eventually leak enough fluid as to risk pump cavitation and system failure, resulting in the loss of the 2B power channel - the most critical of the Space Station's 8 power channels. In mid-2012, the leak rate increased to approximately 5lbm/year. Once discovered, an EVA was planned and executed within a 5 week timeframe to drastically alter the architecture of the PVTCS via connection to a dormant thermal control system not intended to be utilized as anything other than spare components. The purpose of this rerouting of the TCS was to increase system volume and to isolate the photovoltaic radiator, thought to be the likely leak source. This EVA was successfully executed on November 1st, 2012 and left the 2B PVTCS in a configuration where the system was now being adequately cooled via a totally different radiator than what the system was designed to utilize. Unfortunately, data monitoring over the next several months showed that the isolated radiator was not leaking, and the system itself continued to leak steadily until May 9th, 2013. It was on this day that the ISS crew noticed the visible presence of ammonia crystals escaping from the 2B channel's truss segment, signifying a rapid acceleration of the leak from 5lbm/year to 5lbm/day. Within 48 hours of the

  11. Serotonin 2B receptor (5-HT2B R signals through prostacyclin and PPAR-ß/δ in osteoblasts.

    Directory of Open Access Journals (Sweden)

    Yasmine Chabbi-Achengli

    Full Text Available Osteoporosis is due to an imbalance between decreased bone formation by osteoblasts and increased resorption by osteoclasts. Deciphering factors controlling bone formation is therefore of utmost importance for the understanding and the treatment of osteoporosis. Our previous in vivo results showed that bone formation is reduced in the absence of the serotonin receptor 5-HT2B, causing impaired osteoblast proliferation, recruitment, and matrix mineralization. In this study, we investigated the signaling pathways responsible for the osteoblast defect in 5-HT2BR(-/- mice. Notably, we investigated the phospholipase A2 pathway and synthesis of eicosanoids in 5-HT2BR(-/- compared to wild type (WT osteoblasts. Compared to control osteoblasts, the lack of 5-HT2B receptors was only associated with a 10-fold over-production of prostacyclin (PGI2. Also, a specific prostacyclin synthase inhibitor (U51605 rescued totally osteoblast aggregation and matrix mineralization in the 5-HT2BR(-/- osteoblasts without having any effect on WT osteoblasts. Prostacyclin is the endogenous ligand of the nuclear peroxisome proliferator activated receptor ß/δ (PPAR-ß/δ, and its inhibition in 5-HT2BR(-/- cells rescued totally the alkaline phosphatase and osteopontin mRNA levels, cell-cell adhesion, and matrix mineralization. We conclude that the absence of 5-HT2B receptors leads to the overproduction of prostacyclin, inducing reduced osteoblast differentiation due to PPAR-ß/δ -dependent target regulation and defective cell-cell adhesion and matrix mineralization. This study thus reveals a previously unrecognized cell autonomous osteoblast defect in the absence of 5-HT2BR and highlights a new pathway linking 5-HT2B receptors and nuclear PPAR- ß/δ via prostacyclin.

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.

    Full Text Available Many cereal straws have been used as raw materials for the preparation of microcrystalline cellulose (MCC. These raw materials were gradually replaced with wood products; nevertheless about 10% of the world overall pulp production is obtained from non-wood raw material. The main interest in pulp made from straw is that it provides excellent fibres for different industries with special properties, and that it is the major available source of fibrous raw material in some geographical areas. The aim of the present work was to characterize microcrystalline cellulose prepared from alfa fibers using the hydrolysis process. The products obtained are characterized with FTIR spectroscopy and X-ray powder diffraction. As a result, FTIR spectroscopy is an appropriate technique for studying changes occurred by any chemical treatment. The spectrum of alfa grass stems shows the presence of lignin and hemicelluloses. However, the cellulose spectrum indicates that the extraction of lignin and hemicellulose was effective. The X-ray analysis indicates that the microcrystalline cellulose is more crystalline than the source material.

Va más allá de la separación entre Estado e Iglesias y el discurso anticlerical. La Laicidad es un debate sobre los derechos y libertades civiles de los ciudadanos en el respeto de sus derechos humanos por parte de organizaciones, cultos, creencias religiosas.

    Full Text Available Los derechos humanos son individuales, esenciales, inalienables e inherentes a la dignidad de la persona humana, constituyen la base del Estado social de derecho, y son anteriores al derecho positivo. Por su parte, hay otro tipo de derechos que son los colectivos, los cuales radican en cabeza del colectivo social y están ligados a la calidad de vida de las personas. Existe una estrecha relación entre los unos y los otros, pero el interrogante radica en saber cuál prevalece; en la actualidad podría hablarse de una colisión o conflicto que se está presentando entre ambos, esto hace pensar hasta qué punto el crecimiento industrial y tecnológico del mundo es permisible en la medida en que se está comprometiendo el medioambiente y el equilibrio ecológico, lo cual va en detrimento de los derechos a la vida, a la salud y como fundamento último de la persona misma.

    The morphology of a nanomaterial (geometric shape and dimension) has a significant impact on its physical and chemical properties. It is, therefore, essential to determine the morphology of nanomaterials so as to link shape with performance in specific applications. In practice, structural features with different length scales are encoded in a specific angular range of the X-ray or neutron total scattering pattern of the material. By combining small- and wide-angle scattering (typically X-ray) experiments, the full angular range can be covered, allowing structure to be determined accurately at both the meso- and the nanoscale. In this Article, a comprehensive morphology analysis of lithium-ion battery anode material, TiO2 (B) nanoparticles (described in Ren, Y.; Liu, Z.; Pourpoint, F.; Armstrong, A. R.; Grey, C. P.; Bruce, P. G. Angew. Chem. Int. Ed. 2012, 51, 2164), incorporating structure modeling with small-angle X-ray scattering (SAXS), pair distribution function (PDF), and X-ray powder diffraction (XRPD) techniques, is presented. The particles are oblate-shaped, contracted along the [010] direction, this particular morphology providing a plausible rationale for the excellent electrochemical behavior of these TiO2(B) nanoparticles, while also provides a structural foundation to model the strain-driven distortion induced by lithiation. The work demonstrates the importance of analyzing various structure features at multiple length scales to determine the morphologies of nanomaterials.

    The Magnetospheric Multiscale (MMS) formation flying mission, which consists of four spacecraft flying in a tetrahedral formation, has challenging navigation requirements associated with determining and maintaining the relative separations required to meet the science requirements. The baseline navigation concept for MMS is for each spacecraft to independently estimate its position, velocity and clock states using GPS pseudorange data provided by the Goddard Space Flight Center-developed Navigator receiver and maneuver acceleration measurements provided by the spacecraft's attitude control subsystem. State estimation is performed onboard in real-time using the Goddard Enhanced Onboard Navigation System flight software, which is embedded in the Navigator receiver. The current concept of operations for formation maintenance consists of a sequence of two maintenance maneuvers that is performed every 2 weeks. Phase 2b of the MMS mission, in which the spacecraft are in 1.2 x 25 Earth radii orbits with nominal separations at apogee ranging from 30 km to 400 km, has the most challenging navigation requirements because, during this phase, GPS signal acquisition is restricted to less than one day of the 2.8-day orbit. This paper summarizes the results from high-fidelity simulations to determine if the MMS navigation requirements can be met between and immediately following the maintenance maneuver sequence in Phase 2b.

    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.

  8. Vortex lattice structures in YNi2B2C

    The authors observe a flux lattice with square symmetry in the superconductor YNi 2 B 2 C when the applied field is parallel to the c-axis of the crystal. A square lattice observed previously in the isostructural magnetic analog ErNi 2 B 2 C was attributed to the interaction between magnetic order in that system and the flux lattice. Since the Y-based compound does not order magnetically, it is clear that the structure of the flux lattice is unrelated to magnetic order. In fact, they show that the flux lines have a square cross-section when the applied field is parallel to the c-axis of the crystal, since the measured penetration depth along the 100 crystal direction is larger than the penetration depth along the 110 by approximately 60%. This is the likely reason for the square symmetry of the lattice. Although they find considerable disorder in the arrangement of the flux lines at 2.5T, no melting of the vortex lattice was observed

    A poor response to erythropoiesis-stimulating agents such as darbepoetin alfa has been associated with adverse outcomes in patients with diabetes mellitus, chronic kidney disease, and anemia; whether this is also true in heart failure is unclear. We performed a post hoc analysis of the RED-HF trial (Reduction of Events by Darbepoetin Alfa in Heart Failure), in which 1008 patients with systolic heart failure and anemia (hemoglobin level, 9.0-12.0 g/dL) were randomized to darbepoetin alfa. We examined the relationship between the hematopoietic response to darbepoetin alfa and the incidence of all-cause death or first heart failure hospitalization during a follow-up of 28 months. For the purposes of the present study, patients in the lowest quartile of hemoglobin change after 4 weeks were considered nonresponders. The median initial hemoglobin change in nonresponders (n=252) was -0.25 g/dL and +1.00 g/dL in the remainder of patients (n=756). Worse renal function, lower sodium levels, and less use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were independently associated with nonresponse. Although a low endogenous erythropoietin level helped to differentiate responders from nonresponders, its predictive value in a multivariable model was poor (C statistic=0.69). Nonresponders had a higher rate of all-cause death or first heart failure hospitalization (hazard ratio, 1.25; 95% confidence interval, 1.02-1.54) and a higher risk of all-cause mortality (hazard ratio, 1.30; 95% confidence interval, 1.04-1.63) than responders. A poor response to darbepoetin alfa was associated with worse outcomes in heart failure patients with anemia. Patients with a poor response were difficult to identify using clinical and biochemical biomarkers. URL: https://www.clinicaltrials.gov.

    Full Text Available The goal of these studies was to extensively characterize the first recombinant FIX therapeutic corresponding to the threonine-148 (Thr-148 polymorph, IXINITY (trenonacog alfa [coagulation factor IX (recombinant]. Gel electrophoresis, circular dichroism, and gel filtration were used to determine purity and confirm structure. Chromatographic and mass spectrometry techniques were used to identify and quantify posttranslational modifications. Activity was assessed as the ability to activate factor X (FX both with and without factor VIIIa (FVIIIa and in a standard clotting assay. All results were consistent across multiple lots. Trenonacog alfa migrated as a single band on Coomassie-stained gels; activity assays were normal and showed 97%  γ-carboxylation and underwent the appropriate structural change upon binding calcium ions. Trenonacog alfa was activated normally with factor XIa (FXIa; once activated it bound to FVIIIa and FXa. When activated to FIXa, it was inhibited efficiently by antithrombin. Glycosylation patterns were similar to plasma-derived FIX with sialic acid content consistent with the literature reports of good pharmacokinetic performance. These studies have shown that trenonacog alfa is a highly pure product with a primary sequence and posttranslational modifications consistent with the common Thr-148 polymorphism of plasma-derived FIX.

    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.

    Wegrzynek, A.; ALICE Collaboration

    2017-10-01

    ALICE (A Large Ion Collider Experiment) is a heavy-ion detector designed to study the physics of strongly interacting matter (the Quark-Gluon Plasma at the CERN LHC (Large Hadron Collider). ALICE has been successfully collecting physics data in Run 2 since spring 2015. In parallel, preparations for a major upgrade of the computing system, called O2 (Online-Offline), scheduled for the Long Shutdown 2 in 2019-2020, are being made. One of the major requirements of the system is the capacity to transport data between so-called FLPs (First Level Processors), equipped with readout cards, and the EPNs (Event Processing Node), performing data aggregation, frame building and partial reconstruction. It is foreseen to have 268 FLPs dispatching data to 1500 EPNs with an average output of 20 Gb/s each. In overall, the O2 processing system will operate at terabits per second of throughput while handling millions of concurrent connections. The ALFA framework will standardize and handle software related tasks such as readout, data transport, frame building, calibration, online reconstruction and more in the upgraded computing system. ALFA supports two data transport libraries: ZeroMQ and nanomsg. This paper discusses the efficiency of ALFA in terms of high throughput data transport. The tests were performed with multiple FLPs pushing data to multiple EPNs. The transfer was done using push-pull communication patterns and two socket configurations: bind, connect. The set of benchmarks was prepared to get the most performant results on each hardware setup. The paper presents the measurement process and final results - data throughput combined with computing resources usage as a function of block size. The high number of nodes and connections in the final set up may cause race conditions that can lead to uneven load balancing and poor scalability. The performed tests allow us to validate whether the traffic is distributed evenly over all receivers. It also measures the behaviour of

    Although an erythropoiesis-stimulating agent (ESA) is most frequently administered intravenously for treatment of anemia in patients with chronic kidney disease who are on dialysis, few studies have compared the efficacy of different intravenous (i.v.) dosing schedules. This multicenter, phase IIIb, open-label, controlled study randomized 289 stable hemodialysis patients to continue with conventional dosing of i.v. epoetin alfa or darbepoetin, or to switch to once-weekly i.v. epoetin alfa at the same cumulative weekly starting dose, to maintain hemoglobin levels at 11.0-13.0 g/dL, and within 1.0 g/dL of the baseline value. Hemoglobin levels and ESA doses were recorded every 4 weeks for 28 weeks. Hemoglobin levels fell significantly and ESA doses increased significantly between baseline and week 28 (mean of week 16-28 values) in the once-weekly epoetin alfa group, compared with the conventional treatment group (phemoglobin levels between the groups was 0.73 g/dL (greater than the threshold for therapeutic equivalence of 0.5 g/dL). The changes between groups from baseline was significant at all time points for hemoglobin levels (0.36, 0.46, 0.81, 0.87, 0.78, 0.62 and 0.49 g/dL) and from week 12 for ESA dose (718.5, 1,326.5, 1,732.0, 1,839.7 and 1,959.1 IU/week; p=0.005). Hemoglobin was maintained at the target level in 78% and 84% of patients on conventional dosing, and 67% and 64% of those on once-weekly epoetin alfa in the intention-to-treat (p=0.1) and per protocol (p=0.016) populations, respectively. This study did not show therapeutic equivalence of once-weekly i.v. epoetin alfa with conventional dosing regimens.

    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.

    Full Text Available Pompe disease is a rare severe hereditary disease caused by excessive glycogen storage in organs and target tissues due to the acid α-glucosidase gene mutation. Infantile and adult Pompe disease is characterized by involvement of cardiovascular, respiratory and muscular systems in the pathological process. The only specific method of treating Pompe disease is enzyme replacement therapy (intravenous administration of recombinant human acid glucosidase, the effectiveness whereof depends on the time the therapy started. Since such a therapy was introduced into practice, Pompe disease mortality decreased by 79%. 6 children with infantile Pompe disease were observed and treated at the cardiovascular care unit of the Scientific Center of Children’s Health in 2011‑2014. The article presents a clinical case demonstrating capabilities of diagnosing infantile Pompe disease in Russia and effective application of alglucosidase alfa in 4-month-old child.

    GALFA-HI is a survey of Galactic HI conducted with the ALFA seven-beam feed array on the 305 m Arecibo antenna. The survey has both high spatial (FWHM~4') and velocity (0.18 km/s) resolution over 13000 (7520 in DR1) degrees2 of sky between -650 and 650 km/s. Details of the observations and data reduction can be found in Peek et al. (2011ApJS..194...20P). The ALFALFA HI-line survey, now 40% complete, also uses the Arecibo Observatory and its seven-beam feed array to detect potential dwarf galaxies in the vicinity of the Milky Way. The survey, which covers over 7000 (2800 in α.40) deg2 of sky out to 18000 km/s, has the sensitivity to detect 105 Mȯ clouds with 20 km/s linewidths at a distance of 1 Mpc. (2 data files).

    Full Text Available Preocupante é a ascensão do populismo dentro dos Estados Democráticos de Direito, em uma clara afronta e violação aos direitos humanos. Direitos esses que foram arduamente construídos e conquistados pela humanidade ao longo de períodos históricos e tiveram como ápice o fim da Segunda Guerra Mundial e a construção do Sistema Global de Proteção por meio da Organização das Nações Unidas, no século XX. No século XXI, diferentemente do que imaginávamos, caminhamos para um cenário confuso e melancólico, ante as claras e manifestas violações aos direitos humanos por parte dos Estados. Não obstante a comunidade internacional questione a efetividade na tutela dos direitos humanos dentro da ONU, em virtude da inexistência de mecanismos institucionalizados para buscarem a responsabilização internacional do Estado contra graves violações aos direitos humanos, a exemplo do que ocorre dentro do Sistema Interamericano de Proteção aos Direitos Humanos, verificamos que, guardadas as devidas proporções e dentro dos limites de atuação que o próprio direito internacional impõe, a ONU procura atuar eficazmente.

These collective developments allowed for home delivery of on-demand and prophylactic treatment, resulting in the reduction of hemophilia morbidity and mortality and improved quality of life. Although efficacious in treating bleeding, conventional factor products' half-lives require frequent venipuncture, which remains a significant burden to patients. Despite the remarkable advances in hemophilia care, no improvements have, until now, been made to the pharmacokinetic properties of factor products. Multiple strategies have more recently been employed to generate novel bioengineered products that, with great hope, represent the next wave of progress in hemophilia care. The use of these products will undoubtedly raise important discussion about choosing conventional factor over new long-acting factor products. Incorporation of these therapies into clinical care is accompanied by unanswered safety questions that will likely be evaluated only in postmarketing surveillance analysis. Further, these products may change current treatment paradigms with unclear cost repercussions and feasibility. This paper will review efraloctocog alfa (FVIII-Fc and its role in the treatment of hemophilia A. Keywords: hemophilia A, factor VIII, Fc fusion, bioengineered products, efraloctocog alfa

    Star formation, a critical process within galaxies, occurs in the coldest, densest interstellar clouds, whose gas and dust content are observed primarily at radio and infrared wavelengths. The formation of molecular hydrogen (H2) from neutral atomic hydrogen (HI) is an essential early step in the condensation of these clouds from the ambient interstellar medium, but it is not yet completely understood, e.g., what is the predominant trigger? Even more troubling, the abundance of H2 may be severely underestimated by standard tracers like CO, implying significant "dark" H2, and the quantity of HI may also be in error if opacity effects are neglected. We have developed an automated method to account for both HI and H2 in cold, diffuse clouds traced by narrow-line HI 21-cm emission in the Arecibo Inner-Galaxy ALFA (I-GALFA) survey. Our algorithm fits narrow (2-5 km/s), isolated HI line profiles to determine their spin temperature, optical depth, and true column density. We then estimate the "visible" H2 column in the same clouds with CfA and Planck CO data and the total gas column from dust emission measured by Planck, IRAS, and other surveys. Together, these provide constraints on the dark H2 abundance, which we examine in relation to other cloud properties and stages of development. Our aim is to build a database of H2-forming regions with significant dark gas to aid future analyses of coalescing interstellar clouds. We acknowledge support from NSF, NASA, Western Kentucky University, and Williams College. I-GALFA is a GALFA-HI survey observed with the 7-beam ALFA receiver on the 305-meter William E. Gordon Telescope. The Arecibo Observatory is a U.S. National Science Foundation facility operated under sequential cooperative agreements with Cornell University and SRI International, the latter in alliance with the Ana G.

    Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) both have a role to play in follicular development during the natural menstrual cycle. LH supplementation during controlled ovarian stimulation (COS) for assisted reproductive technology (ART) is used for patients with hypogonadotropic hypogonadism. However, the use of exogenous LH in COS in normogonadotropic women undergoing ART is the subject of debate. The aim of this study was to investigate characteristics of infertile women who received the 2:1 formulation of follitropin alfa and lutropin alfa (indicated for stimulation of follicular development in women with severe LH and FSH deficiency) in German clinical practice. A 3-year, multicentre, open-label, observational/non-interventional, post-marketing surveillance study of women (21-45 years) undergoing ART. Primary endpoint: reason for prescribing the 2:1 formulation of follitropin alfa and lutropin alfa. Secondary variables included: COS duration/dose; oocytes retrieved; fertilization; clinical pregnancy; ovarian hyperstimulation syndrome (OHSS). In total, 2220 cycles were assessed; at least one reason for prescribing the 2:1 formulation was given in 1834/2220 (82.6%) cycles. Most common reasons were: poor ovarian response (POR) (39.4%), low baseline LH (17.8%), and age (13.8%). COS: mean dose of the 2:1 formulation on first day, 183.1/91.5 IU; mean duration, 10.8 days. In 2173/2220 (97.9%) cycles, human chorionic gonadotrophin was administered. Oocyte pick-up (OPU) was attempted in 2108/2220 (95.0%) cycles; mean (standard deviation) 8.0 (5.4) oocytes retrieved/OPU cycle. Fertilization (≥1 oocyte fertilized) rates: in vitro fertilization (IVF), 391/439 (89.1%) cycles; intracytoplasmic sperm injection (ICSI)/IVF + ICSI, 1524/1613 (94.5%) cycles. Clinical pregnancy rate: all cycles, 25.9%; embryo transfer cycles, 31.3%. OHSS: hospitalization for OHSS, 8 (0.36%) cycles, Grade 2, 60 (2.7%), and Grade 3, 1 (0.05%). In German routine clinical

    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.         JEL Codes: D23, L86Keywords: Cost, Transaction Costs, Transactions

    Within Europe, Italy has the highest incidence of HCV. PROPHESYS was a large, non-interventional, multinational cohort study of patients treated with peginterferon alfa-2a or -2b/ribavirin for CHC; 22.4% of patients were from Italian centers. This sub-analysis evaluates real-life practice and treatment outcomes in Italy. The PROPHESYS 2 cohort included 1604 HCV mono-infected, treatment-naive patients. All patients were prescribed peginterferon alfa/ribavirin at the discretion of the treating physician according to country-specific requirements. The majority of G1-3 patients were White/Caucasian and 48.4% had HCV G1 infection. Overall, SVR24 rates of 44.9%, 81.4% and 69.1% were achieved in G1-, 2- and 3-infected patients. In G1 patients, SVR24 rates declined with increasing FIB-4 score; this trend was not observed for G2/3-infected patients. Virologic response by Week 2 and 4 was highly predictive of SVR24 (G1: 91.7%, 84.8%; G2: 91.1%, 89.7%; G3: 92.9%, 86.7%, respectively). Absence of virologic response by Week 12 had the highest negative predictive value across genotypes. In Italian patients, a virologic response by Week 2 or 4 was highly predictive of SVR24 across genotypes. These data demonstrate the importance of monitoring on-treatment response to help guide treatment decisions. FIB-4 score correlated well with SVR24 in G1 patients.

    Es argumentada la necesidad de trascender los paradigmas de considerar al trabajador como un costo y también de concebirlo como una inversión de la empresa, asumiendo el paradigma de considerarlo como inversión de su propio capital humano. En consecuencia, el enfoque reductor de personal con el consiguiente desempleo en aras del incremento de la productividad del trabajo, deberá ser superado por el enfoque de optimización del capital humano en la organización. El objetivo de este trabajo es contribuir a esa optimización al ir asumiendo el paradigma del trabajador como inversor de su capital humano, en oposición al desempleo implicado por el paradigma predominante concibiendo al trabajador como un costo.

    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'

    {alpha}{sub 2}-Adrenergic receptors comprise a heterogeneous population based on pharmacologic and molecular evidence. The authors have isolated a cDNA clone (pRNG{alpha}2) encoding a previously undescribed third subtype of an {alpha}{sub 2}-adrenergic receptor from a rat kidney cDNA library. The library was screened with an oligonucleotide encoding a highly conserved region found in all biogenic amine receptors described to date. The deduced amino acid sequence displays many features of G-protein coupled receptors with exception of the absence of the consensus N-linked glycosylation site at the amino terminus. Membranes prepared from COS-1 cells transfected with pRNG{alpha}2 display high affinity and saturable binding to {sup 3}H-rauwolscine (K{sub d}=2 nM).Competition curve data analysis shows that pRNG{alpha}2 protein binds to a variety of adrenergic drugs with the following rank order of potency: yohimbine {ge} cholorpromazine > prazosin {ge} clonidine > norepinephrine {ge} oxymetazoline. pRNG{alpha}2 RNA accumulates in both adult rat kidney and rat neonatal lung (predominant species is 4.0 kb). They conclude that pRNG{alpha}2 likely represents a cDNA for the {alpha}{sub 2B}-adrenergic receptor.

    Full Text Available Ayse Seyhan, Baris AtaDivision of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, McGill University, Montreal, QC, CanadaAbstract: Corifollitropin alfa is a synthetic recombinant follicle-stimulating hormone (rFSH molecule containing a hybrid beta subunit, which provides a plasma half-life of ∼65 hours while maintaining its pharmocodynamic activity. A single injection of corifollitropin alfa can replace daily FSH injections for the first week of ovarian stimulation for in vitro fertilization. Stimulation can be continued with daily FSH injections if the need arises. To date, more than 2500 anticipated normoresponder women have participated in clinical trials with corifollitropin alfa. It is noteworthy that one-third of women did not require additional gonadotropin injections and reached human chorionic gonadotropin criterion on day 8. The optimal corifollitropin dose has been calculated to be 100 µg for women with a body weight ≤ 60 kg and 150 µg for women with a body weight >60 kg, respectively. Combination of corifollitropin with daily gonadotropin-releasing hormone antagonist injections starting on stimulation day 5 seems to yield similar or significantly higher numbers of oocytes and good quality embryos, as well as similar ongoing pregnancy rates compared with women stimulated with daily rFSH injections. Stimulation characteristics, embryology, and clinical outcomes seem consistent with repeated corifollitropin-stimulated assisted reproductive technologies cycles. Multiple pregnancy or ovarian hyperstimulation syndrome rates with corifollitropin were not increased over daily FSH regimen. The corifollitropin alfa molecule does not seem to be immunogenic and does not induce neutralizing antibody formation. Drug hypersensitivity and injection-site reactions are not increased. Incidence and nature of adverse events and serious adverse events are similar to daily FSH injections. Current trials do not

    2017-06-01

    Full Text Available The pressure effects on the lattice parameters and elastic constants of the tetragonal RNi 2 B 2 C (R=Y, Lu are investigated by means of the first principles. The predicted lattice constants and elastic constants of YNi 2 B 2 C and LuNi 2 B 2 C at 0 GPa agree well with the available data. By the elastic stability criteria under isotropic pressure, it is predicted that YNi 2 B 2 C and LuNi 2 B 2 C with tetragonal structure are not mechanically stable above 93 GPa and 50 GPa, respectively. Pugh’s modulus ratio, Poisson’s ratio, Vickers hardness, elastic anisotropy and Debye temperature of YNi 2 B 2 C in the pressure range of 0–100 GPa and LuNi 2 B 2 C in the pressure range of 0-60 GPa are further investigated. It is shown that the ductility and Debye temperature of tetragonal RNi 2 B 2 C (R=Y, Lu increase with increasing pressure, and LuNi 2 B 2 C is more ductile and lower Debye temperature than YNi 2 B 2 C under different pressures.

    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.

    The results of the examination and treatment of 67 patients aged 18 to 45 years are presented. Patients suffered from chronic prostatitis, chronic prostatovesiculitis, chronic uretroprostatitis complicated by excretory-toxic infertility. Pathogens, including sexually transmitted infections (STIs), were identified in all patients. The control group received conventional therapy (causative agents, a-adrenoblockers, enzyme therapy). In the study group, patients received allokin alpha in addition to conventional therapy. The use of allokin-alfa promoted more rapid and complete eradication of STI pathogens, and normalization of the spermogram. The results of this study allow to recommend allokin-alfa for the combined treatment of patients with infectious and inflammatory diseases of the genitourinary system, complicated by excretory-toxic infertility.

    Full Text Available Atualmente, não se pode pensar no estudo do comportamento humano sem considerar a abordagem científica a este objeto: o campo da Psicologia científica. Esse campo é disputado por diversos enfoques teóricos que divergem quanto ao modo como definem ciência e comportamento humano. A abordagem de B. F. Skinner foi bastante proeminente no século XX, mas ainda continua a ser mal-entendida. Partindo do desenvolvimento histórico de sua obra, o presente texto visa a iluminar alguns aspectos relacionados às noções de ciência e comportamento humano desse autor e ressaltar as transformações por que passaram. Analisam-se três tópicos da obra de Skinner: seu período inicial (de 1930 a cerca de 1938, a obra "Ciência e Comportamento Humano" de 1953, e as influências da Biologia. São enfatizados aspectos relevantes da sua teorização sobre o tema: busca por relações funcionais, ênfase nos dados empíricos, operacionismo, externalismo, multideterminação do comportamento, experimentalismo, previsão e controle, ética.

    Primary open angle glaucoma is a progressive optic neuropathy with multiple causative factors including genetic immune disregulation. TNF-alfa has pro-apoptotic effects on the retinal ganglion cells, thus being directly involved in the neurodegeneration of the optic nerve head. Our purpose was to investigate the influence on susceptibility and/or clinical and characteristics of TNF-alfa promoter polymorphism -857 C/T in Romanian patients diagnosed with POAG. We assessed 159 Romanian subjects, 61 diagnosed with glaucoma (F/M 39/22) and 98 healthy unrelated matched controls-HC for the polymorphism -857 C/T, genotyped by Real Time PCR (Taqman SNP Genotyping Assay C_2215707_10, Applied Biosystems, USA). The diagnosis and the staging of the disease in the POAG group were assessed using the current guidelines. Association tests for the SNP were performed using SPSS 11.2 (Fisher test) and p values < or = 0.05 were considered significant. The Hardy-Weinberg equilibrium assessed using Chi-square test was respected in both studied groups- POAG and HC (p = 0.000009 and respectively p = 0.04771). There was no association found between the frequencies of alleles between studied groups (CC/CT/TT= 0.81/0.09/0.08 respectively 0.70/0.23/0.06). TNF-alfa promoter polymorphism -857 C/T doesn't seem to influence the susceptibility to POAG and the results should be confirmed on larger cohorts.

    Full Text Available Este artículo se propone reflexionar sumariamente acerca de la vinculación entre el arte y los derechos humanos, teniendo en cuenta el origen o proveniencia de las manifestaciones artísticas. Para el efecto, se consideran tres tipos de obras: 1. Obras originadas en una decisión judicial o estatal como medio de reparación a las víctimas; 2. Obras de arte provenientes de la propia iniciativa de los artistas, y 3. Obras o prácticas artísticas que realizan las víctimas que han sufrido violaciones a sus derechos humanos. Este texto parte de considerar que las obras de arte o las prácticas artísticas, relacionadas con los derechos humanos, tienen objetivos diferentes según sea su origen. Se plantea que el fin del Estado es reparar a las víctimas y contribuir con la garantía de no repetición; mientras que el fin de los artistas es manifestar su sensibilidad en relación con un tema específico que les interesa abordar; y para las víctimas, son mecanismos de resistencia y denuncia que permiten pasar del trauma individual a la conformación de sujetos colectivos con capacidad para incidir en las condiciones sociales que generan la violación a sus derechos humanos. Para pensar el tema, se abordan algunas sentencias del Sistema Interamericano de Derechos Humanos, y obras y prácticas artísticas de víctimas del conflicto armado colombiano.

  14. Methadone pharmacogenetics: CYP2B6 polymorphisms determine plasma concentrations, clearance and metabolism

    Science.gov (United States)

    Kharasch, Evan D.; Regina, Karen J.; Blood, Jane; Friedel, Christina

    2015-01-01

    Background Interindividual variability in methadone disposition remains unexplained, and methadone accidental overdose in pain therapy is a significant public health problem. Cytochrome P4502B6 (CYP2B6) is the principle determinant of clinical methadone elimination. The CYP2B6 gene is highly polymorphic, with several variant alleles. CYP2B6.6, the protein encoded by the CYP2B6*6 polymorphism, deficiently catalyzes methadone metabolism in vitro. This investigation determined the influence of CYP2B6*6, and other allelic variants encountered, on methadone concentrations, clearance, and metabolism. Methods Healthy volunteers in genotype cohorts CYP2B6*1/*1 (n=21), CYP2B6*1/*6 (n=20), and CYP2B6*6/*6 (n=17), and also CYP2B6*1/*4 (n=1), CYP2B6*4/*6 (n=3), CYP2B6*5/*5 (n=2) subjects received single doses of intravenous and oral methadone. Plasma and urine methadone and metabolite concentrations were determined by tandem mass spectrometry. Results Average S-methadone apparent oral clearance was 35 and 45% lower in CYP2B6*1/*6 and CYP2B6*6/*6 genotypes, respectively, compared with CYP2B6*1/*1, and R-methadone apparent oral clearance was 25 and 30% lower. R- and S-methadone apparent oral clearance was 3- and 4-fold greater in CYP2B6*4 carriers. Intravenous and oral R- and S-methadone metabolism was significantly lower in CYP2B6*6 carriers compared with CYP2B6*1 homozygotes, and greater in CYP2B6*4 carriers. Methadone metabolism and clearance were lower in African-Americans due to the CYP2B6*6 genetic polymorphism. Conclusions CYP2B6 polymorphisms influence methadone plasma concentrations, due to altered methadone metabolism and thus clearance. Genetic influence is greater for oral than intravenous, and S- than R-methadone. CYP2B6 pharmacogenetics explains, in part, interindividual variability in methadone elimination. CYP2B6 genetic effects on methadone metabolism and clearance may identify subjects at risk for methadone toxicity and drug interactions. PMID:26389554

    Since its release in 2004, the i2b2 data warehouse software has become a valuable tool for clinical researchers. Physicians can use its browser-based query frontend intuitively without additional training or reading through documentation. While the i2b2 software describes it's API as "REST", it is neither stateless nor does it follow the common guidelines for RESTful APIs. Thus, interfacing other software with i2b2's custom RPC-style XML-API is a very cumbersome process. To overcome these issues, we developed a lightweight software abstraction layer "lightweight i2b2 façade" (li2b2-façade).

  17. Profile of efraloctocog alfa and its potential in the treatment of hemophilia A.

    Science.gov (United States)

    George, Lindsey A; Camire, Rodney M

    2015-01-01

    Hemophilia care has improved dramatically over the past 50 years, evolving from plasma concentrates, to purified plasma proteins, to recombinant clotting factors. These collective developments allowed for home delivery of on-demand and prophylactic treatment, resulting in the reduction of hemophilia morbidity and mortality and improved quality of life. Although efficacious in treating bleeding, conventional factor products' half-lives require frequent venipuncture, which remains a significant burden to patients. Despite the remarkable advances in hemophilia care, no improvements have, until now, been made to the pharmacokinetic properties of factor products. Multiple strategies have more recently been employed to generate novel bioengineered products that, with great hope, represent the next wave of progress in hemophilia care. The use of these products will undoubtedly raise important discussion about choosing conventional factor over new long-acting factor products. Incorporation of these therapies into clinical care is accompanied by unanswered safety questions that will likely be evaluated only in postmarketing surveillance analysis. Further, these products may change current treatment paradigms with unclear cost repercussions and feasibility. This paper will review efraloctocog alfa (FVIII-Fc) and its role in the treatment of hemophilia A.

  18. 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 studied 13 patients with chronic myeloid leukemia and autoimmune hemolytic anemia induced by interferon alfa. They underwent tests for immune protein detection and characterization of IgG subclasses in RBCs by direct antiglobulin test (PAD) and the microplate technique. Also they were applied ELISA test for quantifying immunoglobulins in the red blood cells. It was detected the presence of IgG and C3 in 53.84 % of cases, IgG alone in 23.07 % and in 15.38 % were identified IgG and IgA autoantibodies. In 11 patients the presence of IgG1 was showed and also in one case the subclass IgG3 autoantibodies was identified. The ELISA detected antibodies at concentrations of 183 IgG molecules per erythrocyte in a patient with negative PAD. In high-grade hemolysis patients, it was found a concentration of autoantibodies between 1 500 and 3 180 molecules of IgG per erythrocyte, while in low-grade hemolysis patients it behaved between 183 and 1 000 molecules. There was a negative correlation between Hb and plasma haptoglobin values with the number of IgG molecules per erythrocyte and a positive correlation between the latter with the reticulocyte count

    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)

    The Po valley in the Northern Italy is a large plain in a semi-closed basin surrounded by complex orography; the Alps to the North and Apennines to the South-East, and closed to the east by the Adriatic sea. As a flatland basin shielded by mountains, calm wind is very frequent and strong temperature inversions are often observed near the ground, during the night and in the winter period the occurrence of a extremely stable boundary layer is common. A complete set of surface and atmospheric measurements have been collected during a four month observational program carried out at San Pietro Capofiume meteo station, in the middle of the Po Valley. The long term dataset has been collected in the contest of the project BASE:ALFA with the main aim of creating a data pool of micro-meteorological /soil data to test and validate numerical weather prediction PBL schemes. The measurement periods span summer, winter and spring and allows to analyse a wide range of PBL stability conditions. Different parameterizations of first and second order moments of velocity and temperature are tested against the collected data. A particular focus is given to stable boundary layer and the values of its height obtained from Nieuwstadt 1984 and Zilitinkievich et al 2005 formulas will be provided and compared against radiosounding profile estimates.

In this prospective, phase IV, observational registry study, children ≤16 years of age with CKD anemia and receiving DA were observed for ≤2 years. Adverse events (AEs), DA dosing, hemoglobin (Hb) concentrations, and transfusions were recorded. A total of 319 patients were included in the analysis (mean age, 9.1 years), 158 (49.5%) of whom were on dialysis at study entry. Of 434 serious AEs reported in 162 children, the most common were peritonitis (10.0%), gastroenteritis (6.0%), and hypertension (4.1%). Six patients (1.9%) died (unrelated to DA). Four patients (1.3%) experienced six serious adverse drug reactions. The geometric mean DA dose range was 1.4-2.0 μg/kg/month. Mean baseline Hb concentration was 11.1 g/dl; mean values for children receiving and not receiving dialysis at baseline ranged between 10.9 and 11.5 g/dl and 11.2-11.7 g/dl, respectively. Overall, 48 patients (15.0%) received ≥1 transfusion. No new safety signals for DA were identified in children receiving DA for CKD anemia for ≤2 years. Based on Hb concentrations and transfusion requirements, DA was effective at managing anemia in these patients.

    Full Text Available Vivimos en un mundo de una opulencia sin precedentes, difícil de imaginar hace sesenta años. Donde no sólo se han registrado notables cambios en el terreno económico, sino en lo social y en lo político. Vivimos inmersos en la cultura de los derechos humanos. La gran idea de la humanidad ha sido y sigue siendo conciliar la universalidad de los valores con las diversas culturas. La Segunda Guerra Mundial fue uno de los episodios más atroces para la Humanidad. Por ello, y como consecuencia lógica al final de la misma, muy a pesar de la tensión que había por lo que acababa de acaecer, se procedió al diseño de un sistema de gobernación mundial basado en la igual dignidad de todos los seres humanos. Eran necesarios para evitar una nueva guerra, es decir, para construir la paz, son necesarios unos nuevos puntos de referencia, unos nuevos asideros éticos que permitan a toda ciudadanía modificar un comportamiento secular basado en la confrontación. El fomento de la dignidad no es una utopía, al contrario, es una necesidad indispensable porque sin ella no pueden concretarse los derechos y deberes humanos de los que tanto dependen la seguridad, supervivencia y felicidad de todos y todas. La pedagogía de la educación en derechos humanos es asumir que todos los seres humanos somos diferentes en nuestras características pero iguales en dignidad y derechos y, por tanto, evitar la discriminación es la finalidad principal, ya que acepta y valora la diversidad como parte de la riqueza de las relaciones humanas. Así pues, del mismo modo que en 1945 se decidió elaborar una Declaración Universal de Derechos Humanos, sería apropiado ahora, en la debacle ética que están sufriendo O ccidente y en particular la Unión Europea, una Declaración Universal sobre la Democracia, porque ha llegado el momento histórico en que la sumisión, el dominio de los pocos sobre los muchos, hemos de darlo por concluido.

    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.

    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.

    1986-01-01

    At relatively high salt concentrations (1.2 M), histone 2B (H2B) and histone 4 (H4) can be covalently crosslinked by irradiation with ultraviolet light to yield a mixture of the three possible dimers: H2B-H2B, H4-H4, and H2B-H4. The formation of the H2B-H4 heterodimer was found to be favored at lower histone concentrations (> 90% H2B-H4 at 0.1 mg/ml total histone protein). CNBr cleavage of the H2B-H4 dimer produced three fragments which were separated by reverse phase HPLC. These fragments were identified by amino acid compositional analysis to be H4(85-102), H2B(62-125), and the crosslinked N-terminal regions H2B(1-59)-H4(1-84). Amino acid sequence analysis of the crosslinked fragment indicated that tyrosine-40 of H2B is likely involved in the covalent crosslinkage which joins the histone monomers to form the heterodimer

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.

    The role of polymorphic CYP2B6 in cyclophosphamide (CPA) bioactivation was investigated in human liver microsomes. A total of 67 human liver specimens were first genotyped with respect to the CYP2B6*5 and CYP2B6*6 variant alleles. CYP2B6 apoprotein levels in 55 liver microsomal preparations were assessed by immunoblotting. 4-Hydroxy-CPA and hydroxy-bupropion were quantified by using HPLC and LC-MS, respectively. 7-Ethoxy-4-trifluoromethyl coumarin O-deethylase activity was measured fluorometrically. The frequencies of CYP2B6*5 and CYP2B6*6 mutant alleles were 9.0 and 16.4%, respectively. CYP2B6 protein expression was detected in 80% of the samples, with a large variation (0.003-2.234, arbitrary units). There was a high correlation between CYP2B6 apoprotein content and CPA 4-hydroxylation (n=55, r=0.81, P<0.0001). When based on the CYP2B6 apoprotein levels, the *6 carriers had significantly higher CPA 4-hydroxylation (P<0.05). CPA 4-hydroxylation also correlated significantly with other CYP2B6-specific reactions (n=20, P<0.0001). V(max) and K(m) for CPA 4-hydroxylation in recombinant CYP2B6 enzyme were 338 nmol/min/nmol enzyme and 1.4 mM, respectively. CYP2B6 showed much higher in vitro intrinsic clearance than previously observed in recombinant CYP2C19 and CYP2C9 variants in yeast expression system. Our results demonstrate that the polymorphic CYP2B6 is a major enzyme in the bioactivation of CPA. Moreover, we identified a strong impact of CYP2B6*6 on CPA 4-hydroxylation.

    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

Em segundo lugar, uma vez constatada a impossibilidade dessa articulação, sustentar que o sentimento de vergonha, presente na moralidade mas também em outras dimensões do desenvolvimento humano, é condição necessária ao sentimento de obrigatoriedade. Finalmente, analisar se tal sentimento é passível de ser evocado como fonte energética essencial nas abordagens que enfatizam a dimensão intelectual da moralidade.

Abarcando os atentados de 11 de setembro, sem que isso se constitua o foco central do estudo, o artigo avalia a validade dessa afirmação ante as vicissitudes empíricas com que os direitos humanos vêm se defrontando nos últimos anos.The article analyses the current situation of human rights, guided by the critic affirmations of the Slovene author Slavoj Zizek, when he supports that the new emerging normativity of the human rights ends to be the form of appearance of its very opposite. Contemplating the 11th of September, without this constitutes the central focus of the study, the article evaluates the validity of these affirmations the empirical vicissitudes which the human rights have been facing in the last years.

    Full Text Available A necessidade constante de um excelente desempenho empresarial leva à busca da qualidade e confiabilidade da informação para o auxílio na tomada de decisão. Neste contexto, a auditoria contábil tem um papel importante na análise das práticas administrativas adotadas pelas entidades. Desse modo, o objetivo deste artigo é comparar a estruturação dos controles internos no contas a receber e a pagar nas empresas Beta Ltda, a qual não contrata serviços de auditoria externa, e Alfa Ltda, que os contrata. Este estudo caracteriza-se como de caso comparativo de caráter descritivo por meio de questionário e entrevista. Os resultados apontam que a empresa Alfa Ltda tem melhores níveis de controle interno e, consequentemente, está menos exposta a erros e fraudes. Desse modo, entende-se que os seviços de auditoria atuam como um instrumento de auxílio para minimização dos riscos operacionais e servem de alerta aos gestores quanto à eficiência das transações. Contudo, percebe-se que a qualidade dos controles internos nas organizações depende diretamente da utilização de procedimentos de monitoramento.The constant need for excellent business performance triggers the quest for information quality and reliability to help in decision making. Considering this context, accounting auditing plays an important role in the analysis of administrative practices adopted by entities. Thus, the objective of this article is to compare the structure of the internal controls for receivable and payable accounts in Beta Ltd companies, which do not contract external auditing services, and Alfa Ltd, which does. This study is a descriptive comparative case study, carried out through questionnaire and interview. The results have showed that Alfa Ltd has better internal control levels and consequently is less exposed to errors and fraud. This way, auditing services are seen as auxiliary instruments to minimize operational risks and serve to alert

    Full Text Available Gaucher disease type 1 is caused by the defective activity of the lysosomal enzyme, acid beta-glucosidase (GCase. Regular infusions of purified recombinant GCase are the standard of care for reversing hematologic, hepatic, splenic, and bony manifestations. Here, similar in vitro enzymatic properties, and in vivo pharmacokinetics and pharmacodynamics (PK/PD and therapeutic efficacy of GCase were found with two human GCases, recombinant GCase (CHO cell, imiglucerase, Imig and gene-activated GCase (human fibrosarcoma cells, velaglucerase alfa, Vela, in a Gaucher mouse, D409V/null. About 80+% of either enzyme localized to the liver interstitial cells and <5% was recovered in spleens and lungs after bolus i.v. injections. Glucosylceramide (GC levels and storage cell numbers were reduced in a dose (5, 15 or 60 U/kg/wk dependent manner in livers (60-95% and in spleens ( approximately 10-30%. Compared to Vela, Imig (60 U/kg/wk had lesser effects at reducing hepatic GC (p = 0.0199 by 4 wks; this difference disappeared by 8 wks when nearly WT levels were achieved by Imig. Anti-GCase IgG was detected in GCase treated mice at 60 U/kg/wk, and IgE mediated acute hypersensitivity and death occurred after several injections of 60 U/kg/wk (21% with Vela and 34% with Imig. The responses of GC levels and storage cell numbers in Vela- and Imig-treated Gaucher mice at various doses provide a backdrop for clinical applications and decisions.

    Full Text Available Background: Despite the availability of a  large number of treatments for multiple sclerosis with various targets, these treatments are not always effective. According to the literature, experimental studies have shown a  significant decrease in tumor necrosis factor alfa (TNF-α with the use of extracorporeal photochemotherapy. Aim: To assess changes in TNF-α in patients with multiple sclerosis during treatment with transimmunization. Materials and methods: The study recruited 13 adult patients with multiple sclerosis. Serum TNF-α was measured by immunochemiluminescence analysis (IMMULITE 1000, Siemens. The patients were treated by transimmunization, i.e. a  modified photopheresis. Two hours before the procedure, Ammifurin (8-methoxypsoralene was administered to all the patients, then their mononuclear cells were isolated under PBSC protocol with Haemonetics MCS+ cell separator. Thereafter, mononuclear cells were irradiated with ultraviolet for 90  minutes and incubated for 20 hours at 37 °С. The next day the cells were re-infused to the patients. The procedure was performed 2  times per week for 6  months, then once per 4  months. Results: Before transimmunization, mean TNF-α level in adult patients with multiple sclerosis was 9.958±0.812  pg/mL (normal, below 8.1 pg/mL. After transimmunization, its level was 6.992±0.367  pg/mL (р<0.05. Conclusion: Ultraviolet irradiation of peripheral blood monocytes with their subsequent incubation (transimmunization led to a 30% decrease of serum TNF-α in patients with multiple sclerosis. This indicates a suppressive effect of transimmunization on TNF-α. Hence, in patients with multiple sclerosis transimmunization exerts an anti-inflammatory effect.

    2005-06-01

    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.

    The catalyst of Ni 2 B nanoparticles was successfully prepared using nickel and boron as precursors with the quenching gas in radio frequency thermal plasmas. The generating of Ni 2 B needs adequate reaction temperature and boron content in precursors. The quenching gas is beneficial for the synthesis of Ni 2 B in RF thermal plasma. The effect of quenching rate, powder feed rate and boron content in feeding powders on the synthesis of nickel boride nanoparticles was studied in this research. The high mass fraction of 28 % of Ni 2 B nanoparticles can be generated at the fixed initial composition of Ni:B = 2:3. Quenching gas is necessary in the synthesis of Ni 2 B nanoaprticles. In addition, the mass fraction of Ni 2 B increases with the increase of quenching gas flow rate and powder feed rate

    Synaptotagmin-1 and -7 constitute the main calcium sensors mediating SNARE-dependent exocytosis in mouse chromaffin cells, but the role of a closely related calcium-binding protein, Doc2b, remains enigmatic. We investigated its role in chromaffin cells using Doc2b knock-out mice and high temporal...... resolution measurements of exocytosis. We found that the calcium dependence of vesicle priming and release triggering remained unchanged, ruling out an obligatory role for Doc2b in those processes. However, in the absence of Doc2b, release was shifted from the readily releasable pool to the subsequent...... sustained component. Conversely, upon overexpression of Doc2b, the sustained component was largely inhibited whereas the readily releasable pool was augmented. Electron microscopy revealed an increase in the total number of vesicles upon Doc2b overexpression, ruling out vesicle depletion as the cause...

  4. Insights into CYP2B6-mediated drug–drug interactions

    Directory of Open Access Journals (Sweden)

    William D. Hedrich

    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.

    2b-RAD (type IIB endonucleases restriction-site associated DNA) approach was invented by Wang in 2012 and proven as a simple and flexible method for genome-wide genotyping. However, there is still plenty of room for improvement for the existent 2b-RAD approach. Firstly, it doesn't include the samples pooling in library preparation as other reduced representation libraries. Secondly, the information of 2b-RAD tags, such as tags numbers and distributions, in most of species are unknown. The purposes of the research are to improve a new 2b-RAD approach which possesses samples pooling, moreover to figure out the characteristic and application potentiality of 2b-RAD tags by bioinformatics analysis. Twelve adapter1 and an adapter2 were designed. A library approach comprising digestion, ligation, pooling, PCR and size selection were established. For saving costs, we used non-phosphorylated adapters and indexed PCR primers. A F2 population of rice (Oryza sativa .L) was genotyped to validate the new approach. On average, 2000332 high quality reads of each sample were obtained with high evenness. Totally 3598 markers containing 3804 SNPs were discovered and the missing rate was 18.9%. A genetic linkage map of 1385 markers was constructed and 92% of the markers' orders in the genetic map were in accordance with the orders in chromosomes. Meanwhile, the bioinformatics simulation in 20 species showed that the BsaXI had the most widespread recognition sites, indicating that 2b-RAD tags had a powerful application potentiality for high density genetic map. Using modified adapters with a fix base in 3'end, 2b-RAD was also fit for QTL studies with low costs. An improved 2b-RAD genotyping approach was established in this research and named as I2b-RAD. The method was a simple, fast, cost-effective and multiplex sequencing library approach. It could be adjusted by selecting different enzymes and adapters to fit for alternative uses including chromosomes assembly, QTL fine mapping and

En primer lugar examina la evolución de la situación en América Latina en los últimos 20 años, mostrando como el paso de dictaduras a gobiernos elegidos democráticamente no necesariamente se reflejó en una mejoría en los derechos humanos. Luego de describir el funcionamiento de la Comisión y la Corte Interamericanas de Derechos Humanos, analiza dos tendencias presentes en el actual debate sobre el futuro del sistema interamericano. Una posición calificada como "promoción-reforma" entiende que el sistema debería orientarse hacia actividades exclusivamente de promoción de los derechos humanos antes que tareas de protección. Para ello proponen reformar la Convención Americana sobre Derechos Humanos. La segunda posición , la denomina "protección-perfeccionamiento" ya que sostiene que la realidad actual de América Latina, requiere que la Comisión y la Corte se dediquen fundamentalmente a la protección de los derechos humanos. Finalmente el artículo presenta cinco objetivos que deberían orientar el trabajo del sistema y muestra cómo las dos posiciones anteriormente mencionadas difieren en cuanto a estos objetivos o a la manera de alcanzarlos.ABSTRACT: The article analizes the current debate within the inter-American System of human rights.

    The majority of sporadic forms of colorectal carcinomas is characterized by deregulation of Wnt/β-catenin signaling early in colorectal carcinogenesis. As a consequence, ITF-2B protein levels are increased in adenomas of these patients. However, ITF-2B protein levels are strongly reduced with increasing carcinoma stages, suggesting that reduction of ITF-2B protein is required for progression of adenomas to colorectal carcinomas. To find out if ITF-2B protein levels are correlated with the survival of patients with colorectal carcinomas, a tissue microarray containing samples from 213 colorectal carcinomas (T-categories T2 and T3) with corresponding survival information was stained with an ITF-2B antibody. In addition, we analyzed if detection of ITF-2B in microsatellite instable and microsatellite stable carcinomas as well as in colorectal carcinomas with KRAS mutations is correlated with survival. Detection of cytoplasmic ITF-2B protein was associated with better overall and progression free survival of patients with colorectal carcinomas (P=0.033 and 0.024, respectively). Multivariate Cox regression analysis revealed an increased risk to suffer from poor overall survival and recurrent disease if no cytoplasmic ITF-2B was detectable (HR=1.91; P=0.033 and HR=1.75; P=0.033, respectively). Similarly, patients with MSS carcinomas had a better overall survival, if they showed cytoplasmic positivity for ITF-2B (P=0.013). Remarkably, patients with colorectal carcinomas carrying KRAS mutations had a better overall and progression free survival rate if the carcinomas were positive for cytoplasmic ITF-2B (HR=4.71; P=0.002 and HR=2.57; P=0.024, respectively). These data suggest that cytoplasmic protein levels of ITF-2B could be used as a prognostic marker for patients with colorectal carcinomas. PMID:26328254

  15. The macrophage A2B adenosine receptor regulates tissue insulin sensitivity.

    Full Text Available High fat diet (HFD-induced type 2 diabetes continues to be an epidemic with significant risk for various pathologies. Previously, we identified the A2b adenosine receptor (A2bAR, an established regulator of inflammation, as a regulator of HFD-induced insulin resistance. In particular, HFD was associated with vast upregulation of liver A2bAR in control mice, and while mice lacking this receptor showed augmented liver inflammation and tissue insulin resistance. As the A2bAR is expressed in different tissues, here, we provide the first lead to cellular mechanism by demonstrating that the receptor's influence on tissue insulin sensitivity is mediated via its expression in macrophages. This was shown using a newly generated transgenic mouse model expressing the A2bAR gene in the macrophage lineage on an otherwise A2bAR null background. Reinstatement of macrophage A2bAR expression in A2bAR null mice fed HFD restored insulin tolerance and tissue insulin signaling to the level of control mice. The molecular mechanism for this effect involves A2bAR-mediated changes in cyclic adenosine monophosphate in macrophages, reducing the expression and release of inflammatory cytokines, which downregulate insulin receptor-2. Thus, our results illustrate that macrophage A2bAR signaling is needed and sufficient for relaying the protective effect of the A2bAR against HFD-induced tissue inflammation and insulin resistance in mice.

    Type I interferons (IFNs) inhibit viral replication and cell growth and enhance the immune response, and therefore have many clinical applications. IFN-alpha2b ranks third in world market use for a biopharmaceutical, behind only insulin and erythropoietin. The average annual cost of IFN-alpha2b for the treatment of hepatitis C infection is $26,000, and is therefore unavailable to the majority of patients in developing countries. Therefore, we expressed IFN-alpha2b in tobacco chloroplasts, and transgenic lines were grown in the field after obtaining United States Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) approval. Stable, site-specific integration of transgenes into chloroplast genomes and homoplasmy through several generations were confirmed. IFN-alpha2b levels reached up to 20% of total soluble protein, or 3 mg per gram of leaf (fresh weight). Transgenic IFN-alpha2b had similar in vitro biological activity to commercially produced PEG-Introntrade mark when tested for its ability to protect cells against cytopathic viral replication in the vesicular stomatitis virus cytopathic effect (VSV CPE) assay and to inhibit early-stage human immunodeficiency virus (HIV) infection. The antitumour and immunomodulating properties of IFN-alpha2b were also seen in vivo. Chloroplast-derived IFN-alpha2b increased the expression of major histocompatibility complex class I (MHC I) on splenocytes and the total number of natural killer (NK) cells. Finally, IFN-alpha2b purified from chloroplast transgenic lines (cpIFN-alpha2b) protected mice from a highly metastatic tumour line. This demonstration of high levels of expression of IFN-alpha2b, transgene containment and biological activity akin to that of commercial preparations of IFN-alpha2b facilitated the first field production of a plant-derived human blood protein, a critical step towards human clinical trials and commercialization.

    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.

Os indivíduos com esta deficiência podem ser assintomáticos, sendo que a manifestação mais prevalente, também apontada como a maior causa de invalidez e morte nesses pacientes, é a doença pulmonar obstrutiva crónica. Nos indivíduos portadores da doença, o tabagismo constitui o factor de risco mais importante. A doença é muito pouco diagnosticada. Várias estratégias de tratamento têm sido utilizadas.REV PORT PNEUMOL 2004; X (2: 145-154 ABSTRACT: Alpha-1-antitrypsin deficiency is an autosomal hereditary disorder and the large majority of individuals with severe deficiency are protease inhibitor type ZZ. The disease occurs predominantly in white persons of European origin and its frequency in Europe and North America is comparable to that of cystic fibrosis (1 in 2000 to 1 in 7000. Persons with this deficiency may have no clinical manifestations, but the most prevalent clinical disorder associated, also pointed as the most frequent cause of disability and death, is chronic obstructive pulmonary disease. In those individuals, tobacco smoking is the major risk. The condition appears to be widely underdiagnosed, based on studies. Several strategies have been explored in the treatment of this deficiency.REV PORT PNEUMOL 2004; X (2: 145-154 Palavras-chave: alfa-1-antitripsina, doença pulmonar obstrutiva crónica, Key-words: alpha-1-antitripysin, chronic obstructive pulmonary disease

  20. Estimadores de consistencia interna en las investigaciones en salud: el uso del coeficiente alfa

    Full Text Available La producción académica ha aumentado en el área de la salud, exigiendo cada vez más calidad en las publicaciones de gran impacto. Una de las formas de considerar la calidad es por medio de procedimientos que aumentan la consistencia del análisis de los datos, como la confiabilidad, que dependiendo del tipo de datos, puede ser evaluada por diferentes coeficientes, en especial el coeficiente alfa. Basados en lo anterior, la presente revisión reúne sistemáticamente artículos científicos producidos en los últimos cinco años, que de manera metodológica hicieron uso psicométrico del coeficiente α como un estimador de consistencia interna y de confiabilidad en procesos de construcción, adaptación y validación de instrumentos. La identificación de los estudios fue realizada sistemáticamente en las bases de datos Biomed Central Journals, Google Scholar, Web of Science, Wiley Online Library, Medline via Pubmed, Scielo, Scopus, Journals@Ovid, BMJ y Springer por medio del Portal de Periódicos CAPES, utilizando criterios de inclusión y exclusión. El análisis de los datos fue realizado por medio de triangulación, análisis de contenido y análisis descriptivo. Se obtuvo que la mayoría de los estudios fueron realizados principalmente en Irán (f=3, España (f=2 y Brasil (f=2, estos estudios tuvieron como objetivo testar las propiedades psicométricas de instrumentos, siendo que ocho estudios utilizaron el coeficiente α para evaluar la confiabilidad y nueve para evaluar la consistencia interna. Todos los estudios fueron clasificados como investigaciones metodológicas al analizar sus objetivos. Adicionalmente, cuatro estudios también fueron clasificados como correlacionales y uno como descriptivo-correlacional. Se puede concluir que a pesar de que el coeficiente α es ampliamente utilizado como uno de los principales parámetros para la evaluación de consistencia interna de instrumentos de medición del tipo cuestionario en el

    Currently interferon alfa-2b (IFNα-2b) is an approved adjuvant drug for high-risk melanoma patients that leads to an improvement in disease-free survival (DFS). However, it is unclear whether it also impacts overall survival. Widespread use of adjuvant high-dose IFNα has been tempered by its significant toxicity and its limited efficacy. Current therapeutic strategies like immune checkpoint blockade or targeted therapy may also be useful in the adjuvant setting. Therefore, it is important to weigh the trade-offs between possible side effects and therapeutic benefit.We assessed patient utilities for health states associated with IFN therapy. Utilities are measures of preference for a specific health state on a scale of 0 (death) to 1 (perfect health).Utilities were determined for health states associated with adjuvant IFN among 130 German low-risk melanoma patients using the standard gamble technique. Four IFNα-2b toxicity scenarios and the following 3 posttreatment outcomes were assessed: disease-free health and melanoma recurrence (with or without previous use of IFNα-2b) resulting in cancer death. Patients were asked to trade-off the improvement in 5-year DFS and the IFN-related side effects.Utilities for melanoma recurrence (mean 0.60) were significantly lower than for all IFNα-2b toxicity scenarios (mean 0.81-0.90). Patients were willing to tolerate mild-to-moderate and severe toxicity for a 50% and 75% chance of 5-year DFS, respectively. Both utilities and threshold benefits were mostly independent from patient characteristics like gender, income, and social situation. Significant impact was only observed by age and previous personal experience with cancer.On average, German patients were willing to trade even severe IFNα-2b toxicity for reducing the rate of melanoma recurrence. This result points out the importance of a relapse-free survival for melanoma patients. The utilities measured in our study can be applied to decision-making processes in

    Full Text Available En un ambiente como el actual, de gran competencia, cambios rápidos y permanentes, la supervivencia de una organización depende de su capacidad para generar valor agregado a sus clientes y proveedores, lo cual será la base de su competitividad y posicionamiento en el mercado, pero esto, a su vez, depende de la capacidad de innovación, velocidad de respuesta, adaptabilidad al cambio y habilidad para detectar las necesidades de los participantes en la cadena de valor de la organización. El capital humano constituye un activo intangible que tiene la capacidad de apoyar el incremento de la productividad, impulsar la innovación y con ello la competitividad. Su misma naturaleza le da características definitivamente distintivas de cualquier otro tipo de recurso. Sin lugar a dudas el éxito de cualquier organización se vincula estrechamente al desempeño de todas las personas que la integran, sin importar su jerarquía, ubicación y condición, pues son ellas las que poseen habilidades, conocimientos, relaciones sociales, actitudes, valores, etc., y son ellas las que deciden dónde, cuándo y cómo utilizarlos. Los recursos humanos son fuente de ventaja competitiva de las organizaciones, por ello las empresas cada vez en mayor medida deben identificar el valor que la persona tiene para la organización y tratar de potenciarlo, al igual deben incrementar el valor que la empresa tiene para el empleado, con el fin de captar a las mejores personas y reducir el riesgo de transferibilidad de un activo tan valioso como es el capital humano.

    Antecedentes


    Siendo el recurso humano el en cargado de movilizar los demás recursos e impulsarlos de tal manera que conlleve a una dinámica de producción masiva de bienes o servicios, su estudio para llegar a una identificación real, categorización, clasificación; es necesario en cualquier área del conocimiento.

    Frente al nuevo esquema de prestación de servicios propuestos, los profesionales de la salud han perdido aquella posición digna, de respeto y liderazgo dentro del sistema y dentro de su entorno social, lo cual ha llevado a muchos de ellos a desertar de sus oficios originales, con lo cual se llega a la falla en la instauración del Sistema.

    Así mismo la Ley 100 de 1993 que debió ser vista como una nueva oportunidad de negocios dentro de las diferentes profesiones de la salud, se transformó en una seria amenaza para el ejercicio independiente de cada profesión.

    No es apropiado ni satisfactorio dejar un proceso decisorio de tal magnitud en manos de otros sectores que únicamente verán y obtendrán estadísticas del acceso de la población colombiana a estudios superiores y los renglones en los cuales quieren desempeñarse y se desempeñarán en un futuro. El sector de la salud debe tomar un claro papel protagónico frente a la promulgación de políticas de formación y utilización de su recurso humano.

    La Academia Nacional de Medicina consciente del vacío existente en el sector con respecto al tema, ha querido desde su posición estratégica con respecto a las profesiones del área y las universidades, liderar un proceso que conlleve a la organización de un Estudio del recurso humano del Sector Salud en Colombia, tomando como punto de partida el censo de los trabajadores de la salud en todas las áreas, de tal manera que se identifique su disponibilidad, su capacidad, la ubicación, las facilidades laborales en zonas aisladas y su grado de satisfacción, entre otras

    Full Text Available En la medida en que el tráfico de estupefacientes, el fraude, el blanqueo de dinero y toda una gama de otros delitos trascienden las fronteras nacionales, los responsables de luchar contra esta delincuencia deben encontrar medios eficaces para obtener las pruebas necesarias que, naturalmente, se encontrarán a menudo más allá de sus propias fronteras. Hace ya casi quince años se implementó un instrumento que facilita ese acceso. El Convenio sobre la Ciberdelincuencia, conocido también como Convenio de Budapest sobre la Ciberdelincuencia o Convenio de Budapest, es el primer tratado internacional que intenta abordar los delitos informáticos y los delitos en Internet, incluida la pornografía infantil, armonizando ciertas leyes nacionales, mejorando las técnicas de investigación y aumentando la cooperación entre las naciones y la adecuada protección de los derechos humanos y las libertades en cumplimiento del Convenio Europeo para la Protección de los Derechos Humanos y de las Libertades Fundamentales. La realidad de 2017 es que la presencia de nuevos elementos, especialmente relativos a la recopilación de datos más personales en el ciberespacio, plantea nuevos desafíos y requiere nuevas ideas. El Convenio permite esta ampliación mediante reflexiones, directrices nuevas y protocolos. Está abierto a todos y es el único instrumento de este tipo. No está completo, sino que deja lugar a la adopción de protocolos futuros y, sobre todo, permite a los grupos de trabajo, entre los regionales que trabajan en el campo de la ciberdelincuencia o la asistencia judicial recíproca, desarrollar nuevas maneras de fortalecer la lucha contra la delincuencia, respetando al mismo tiempo los derechos humanos.

    Full Text Available El humanismo y el poshumanismo son movimientos intelectuales diferentes y relacionados para el entendimiento del ser humano. El humanismo renacentista y de la modernidad plantea que el ser humano es el sujeto autónomo de la modernidad, dueño de la voluntad y poseedor único de la razón, que lo distingue de las demás especies. Este humanismo, vi - sión del mundo que sustentó el pensamiento occidental durante años, ha sido severamente criticado por los filósofos que destacaron sus limitaciones teóricas y éticas inspiradas por la aparición de la cibernética y las nuevas tecnologías. El poshumanismo, mediante la investigación científica y las tecnologías avanzadas, aboga por la reconfiguración de la naturaleza humana y la creación de seres biológica y tecnológicamente superiores al homo sapiens; esto es posible mejorando el funcionamiento del cerebro, controlando la procreación, retrasando el envejecimiento, y así lograr la inmortalidad. El acaecimiento de esta forma de ver mundo puede ser superado desde la nostalgia humanística, exaltando en su totalidad las cualidades propias de la naturaleza humana y dándole sentido racional y moral a la vida. El proyecto de mejoramiento humano ejerce influencia amplia y profunda sobre la cultura y la sociedad contemporánea, por ello se ofrece una crítica desde un acercamiento sinérgico de estas posturas

    Outcomes from 5 years of treatment with agalsidase alfa enzyme replacement therapy (ERT) for Fabry disease in patients enrolled in the Fabry Outcome Survey (FOS) were compared with published findings for untreated patients with Fabry disease. Data were extracted from FOS, a Shire-sponsored database, for comparison with data from three published studies. Outcomes evaluated were the annualized rate of change in estimated glomerular filtration rate (eGFR) and left ventricular mass indexed to height (LVMI) as well as time to and ages at a composite morbidity endpoint and at death. FOS data were extracted for 740 treated patients who were followed for a median of ~ 5 years. Compared with no treatment, patients treated with agalsidase alfa demonstrated slower decline in renal function and slower progression of left ventricular hypertrophy. Treated male patients with baseline eGFR Fabry disease in slowing the progression of renal impairment and cardiomyopathy. Treatment also appeared to delay the onset of morbidity and mortality. Interpretation of these findings should take into account that they are based on retrospective comparisons with previously published data.

    Drug development for ultra-rare diseases is challenging because small sample sizes and heterogeneous study populations hamper the ability of randomized, placebo-controlled trials with a single primary endpoint to demonstrate valid treatment effects. To overcome these challenges, a novel Blind Start design was utilized in a study of vestronidase alfa in mucopolysaccharidosis VII (Sly syndrome), an ultra-rare lysosomal disease, that demonstrates the strengths of this approach in a challenging drug-development setting. Twelve subjects were randomized to 1 of 4 blinded groups, each crossing over to active treatment in a blinded fashion at different timepoints with efficacy analysis comparing the last assessment before cross over to after 24 weeks of treatment. Study assessments included: Percentage change from baseline in urinary GAG (uGAG); a Multi-Domain Responder Index (MDRI) using prespecified minimal important differences (6-Minute Walk Test, Forced Vital Capacity, shoulder flexion, visual acuity, and Bruininks-Oseretsky Test of Motor Proficiency); fatigue as assessed by the Pediatric Quality of Life Inventory™ Multidimensional Fatigue Scale; and safety. Vestronidase alfa treatment for 24 weeks significantly reduced uGAG excretion (dermatan sulfate: 64.8%, p design improve statistical power that enhances detection of a positive treatment effect in this rare heterogeneous disease and could be utilized for other ultra-rare diseases.

    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 The article is devoted to specific disorders of the respiratory system in cystic fibrosis. 64 patients with cystic fibrosis (CF aged 2 months to 32 years and residing in the Udmurtian Republic were studied. Epidemiological and genetic specifics of this disease in the mentioned region of the RF were examined. Clinical, X-ray, functional and microbiological studies of the CF patients’ respiratory system were conducted. It was found that genotype delF508 and chronic infection Pseudomonas aeruginosa, Staphylococcus aureus cause severe structural changes to the bronchopulmonary system more often. The obtained data suggest the advisability of identifying the groups of CF patients at the highest risk of severe respiratory system disorders in order to optimise therapeutic efforts. The article provides indicators of clinical efficacy of a dornase alfa therapy in CF children.Key words: cystic fibrosis, genotype, delF508 mutation, respiratory organs, pseudomonas aeruginosa infection, staphylococcal infection, respiratory function, mucolytic function, dornase alfa.

  7. Multiple roles for UDP-glucuronosyltransferase (UGT)2B15 and UGT2B17 enzymes in androgen metabolism and prostate cancer evolution.

    Science.gov (United States)

    Gauthier-Landry, Louis; Bélanger, Alain; Barbier, Olivier

    2015-01-01

    In the prostate, approximately 50% of androgens are from adrenal steroids, mainly dehydroepiandrosterone (DHEA), its sulfate and androstenedione. These compounds are converted first into testosterone, and then into the active hormone dihydrotestosterone (DHT). After having activated the androgen receptor (AR), DHT is reduced into androstane-3α-DIOL (3α-DIOL) and androsterone (ADT), which are subsequently converted into 2 inactive and easily excretable metabolites: 3α-DIOL-17glucuronide (3α-DIOL-17G) and ADT-3glucuronide (ADT-3G). The formation of these last derivatives through the glucuronidation reaction involves 2 UDP-glucuronosyltransferase (UGT) enzymes, namely UGT2B15 and UGT2B17. The present review article aims at providing a comprehensive view of the physiological and pharmacological importance of these 2 enzymes for the control of androgen homeostasis. We will resume: (i) how UGT2B15 and UGT2B17 contribute to androgen elimination; (ii) how their glucuronidation capacity influences the androgen signaling pathway in prostate cells; (iii) how they contribute to the anti-proliferative properties of AR antagonists in prostate cancer cells; and (iv) how AR and its spliced variants regulate the UGT2B15 and/or UGT2B17 genes expression. Finally, whether the unexploited AR-UGT axis could serve as a prognostic maker or a pharmacological target for novel therapeutics in the treatment of prostate cancer is also discussed.

  8. AMP and adenosine are both ligands for adenosine 2B receptor signaling.

    Holien, Jessica K; Seibt, Benjamin; Roberts, Veena; Salvaris, Evelyn; Parker, Michael W; Cowan, Peter J; Dwyer, Karen M

    2018-01-15

    Adenosine is considered the canonical ligand for the adenosine 2B receptor (A 2B R). A 2B R is upregulated following kidney ischemia augmenting post ischemic blood flow and limiting tubular injury. In this context the beneficial effect of A 2B R signaling has been attributed to an increase in the pericellular concentration of adenosine. However, following renal ischemia both kidney adenosine monophosphate (AMP) and adenosine levels are substantially increased. Using computational modeling and calcium mobilization assays, we investigated whether AMP could also be a ligand for A 2B R. The computational modeling suggested that AMP interacts with more favorable energy to A 2B R compared with adenosine. Furthermore, AMPαS, a non-hydrolyzable form of AMP, increased calcium uptake by Chinese hamster ovary (CHO) cells expressing the human A 2B R, indicating preferential signaling via the G q pathway. Therefore, a putative AMP-A 2B R interaction is supported by the computational modeling data and the biological results suggest this interaction involves preferential G q activation. These data provide further insights into the role of purinergic signaling in the pathophysiology of renal IRI. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Hyperphosphatemia is common in chronic kidney disease and is associated with morbidity and mortality. The intestinal Na + -dependent phosphate transporter Npt2b is thought to be an important molecular target for the prevention of hyperphosphatemia. The role of Npt2b in the net absorption of inorganic phosphate (Pi), however, is controversial. In the present study, we made tamoxifen-inducible Npt2b conditional knockout (CKO) mice to analyze systemic Pi metabolism, including intestinal Pi absorption. Although the Na + -dependent Pi transport in brush-border membrane vesicle uptake levels was significantly decreased in the distal intestine of Npt2b CKO mice compared with control mice, plasma Pi and fecal Pi excretion levels were not significantly different. Data obtained using the intestinal loop technique showed that Pi uptake in Npt2b CKO mice was not affected at a Pi concentration of 4 mM, which is considered the typical luminal Pi concentration after meals in mice. Claudin, which may be involved in paracellular pathways, as well as claudin-2, 12, and 15 protein levels were significantly decreased in the Npt2b CKO mice. Thus, Npt2b deficiency did not affect Pi absorption within the range of Pi concentrations that normally occurs after meals. These findings indicate that abnormal Pi metabolism may also be involved in tight junction molecules such as Cldns that are affected by Npt2b deficiency.

    Full Text Available Abstract Background Branchiomotor neurons comprise an important class of cranial motor neurons that innervate the branchial-arch-derived muscles of the face, jaw and neck. They arise in the ventralmost progenitor domain of the rhombencephalon characterized by expression of the homeodomain transcription factors Nkx2.2 and Phox2b. Phox2b in particular plays a key role in the specification of branchiomotor neurons. In its absence, generic neuronal differentiation is defective in the progenitor domain and no branchiomotor neurons are produced. Conversely, ectopic expression of Phox2b in spinal regions of the neural tube promotes cell cycle exit and neuronal differentiation and, at the same time, induces genes and an axonal phenotype characteristic for branchiomotor neurons. How Phox2b exerts its pleiotropic functions, both as a proneural gene and a neuronal subtype determinant, has remained unknown. Results To gain further insights into the genetic program downstream of Phox2b, we searched for novel Phox2b-regulated genes by cDNA microarray analysis of facial branchiomotor neuron precursors from heterozygous and homozygous Phox2b mutant embryos. We selected for functional studies the genes encoding the axonal growth promoter Gap43, the Wnt antagonist Sfrp1 and the transcriptional regulator Sox13, which were not previously suspected to play roles downstream of Phox2b and whose expression was affected by Phox2b misexpression in the spinal cord. While Gap43 did not produce an obvious phenotype when overexpressed in the neural tube, Sfrp1 induced the interneuron marker Lhx1,5 and Sox13 inhibited neuronal differentiation. We then tested whether Sfrp1 and Sox13, which are down-regulated by Phox2b in the facial neuron precursors, would antagonize some aspects of Phox2b activity. Co-expression of Sfrp1 prevented Phox2b from repressing Lhx1,5 and alleviated the commissural axonal phenotype. When expressed together with Sox13, Phox2b was still able to promote

    Full Text Available First-principles calculations combined with homogeneous deformation methods are used to investigate the second- and third-order elastic constants of YNi2B2C with tetragonal structure. The predicted lattice constants and second-order elastic constants of YNi2B2C agree well with the available data. The effective second-order elastic constants are obtained from the second- and third-order elastic constants for YNi2B2C. Based on the effective second-order elastic constants, Pugh’s modulus ratio, Poisson’s ratio, and Vickers hardness of YNi2B2C under high pressure are further investigated. It is shown that the ductility of YNi2B2C increases with increasing pressure.

RESULTS: We show that CHMP2B can be efficiently knocked down in patient fibroblasts using an RNA interference approach......BACKGROUND: Frontotemporal dementia is the second most common form of young-onset dementia after Alzheimer's disease, and several genetic forms of frontotemporal dementia are known. A rare genetic variant is caused by a point mutation in the CHMP2B gene. CHMP2B is a component of the ESCRT......-III complex, which is involved in endosomal trafficking of proteins targeted for degradation in lysosomes. Mutations in CHMP2B result in abnormal endosomal structures in patient fibroblasts and patient brains, probably through a gain-of-function mechanism, suggesting that the endosomal pathway plays a central...

    assays, we show that histone H3 acetylation at Lys 9 (H3K9Ac) was elevated over gluconeogenic genes and contributed to increased hepatic glucose production during fasting and in diabetes. Dephosphorylation of CRTC2 promoted increased H3K9Ac through recruitment of the lysine acetyltransferase 2B (KAT2B......) and WD repeat-containing protein 5 (WDR5), a core subunit of histone methyltransferase (HMT) complexes. KAT2B and WDR5 stimulated the gluconeogenic program through a self-reinforcing cycle, whereby increases in H3K9Ac further potentiated CRTC2 occupancy at CREB binding sites. Depletion of KAT2B or WDR5...... decreased gluconeogenic gene expression, consequently breaking the cycle. Administration of a small-molecule KAT2B antagonist lowered circulating blood glucose concentrations in insulin resistance, suggesting that this enzyme may be a useful target for diabetes treatment....

    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.

    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

Despite clinical treatment advancements, the prognosis of patients with glioma remains poor. KDM2B is a histone lysine demethylase, which has been observed in multiple tumors. But the concrete role of KDM2B in gliomas remains to be further illustrated.Methods: The KDM2B expression in gliomas was detected with immunohistochemistry and Western blot assay. Furthermore, knockdown of KDM2B in U87 and U251 glioma cell lines, the proliferation capacity was evaluated by cell viability assay, colon formation assay and flow cytometry in vitro. Western blot assay was used to analyze the p21, EZH2 and cyclinD1 changes followed by knockdown of KDM2B.Results: KDM2B was upregulated in tissues of glioma patients, and the expression was correlated to cancer progression. Downregulation of KDM2B in U87 and U251 glioma cell lines inhibited cell proliferation and arrested cell cycle in G0/G1 phase. In addition, silencing KDM2B promoted the upregulation of p21 while reduced the expression of EZH2 and cyclinD1.Conclusion: Taken together, our results revealed that KDM2B might influence gliomas growth and act as a novel therapeutic target for glioma patients.Keywords: EZH2, glioma, KDM2B, P21

    The authors isolated a cDNA clone (RB{alpha}{sub 2B}) and its homologous gene (GR{alpha}{sub 2B}) encoding an {alpha}{sub 2B}-adrenergic receptor subtype by screening a rat brain cDNA and a rat genomic library. Nucleotide sequence analysis showed that both clones code for a protein of 458 amino acids, which is 87% homologous to the human kidney glycosylated adrenergic receptor ({alpha}{sub 2}-C4) and divergent from the rat kidney nonglycosylated {alpha}{sub 2B} subtype (RNG{alpha}{sub 2}). Transient expression of RB{alpha}{sub 2B} in COS-7 cells resulted in high-affinity saturable binding for ({sup 3}H)rauwolscine and a high receptor number in the membranes of transfected COS-7 cells. Pharmacological analysis demonstrated that the expressed receptor bound adrenergic ligands with the following order of potency: rauwolscine {gt} yohimbine {gt} prazosin {gt} oxymetazoline, with a prazosin-to-oxymetazoline K{sub i} ratio of 0.34. This profile is characteristic of the {alpha}{sub 2B}-adrenergic receptor subtype. Blotting analysis of rat brain mRNA gave one major and two minor mRNA species, and hybridization with strand-specific probes showed that both DNA strands of GR{alpha}{sub 2B} may be transcriptionally active. These findings show that rat brain expresses an {alpha}{sub 2B}-adrenergic receptor subtype that is structurally different from the rat kidney nonglycosylated {alpha}{sub 2B} subtype. Thus the rat expresses at least two divergent {alpha}{sub 2B}-adrenergic receptors.

    Full Text Available Abstract Background Cyclin-dependent kinase inhibitor 2A/2B (CDKN2A/2B near chromosome 9p21 have been associated with both atherosclerosis and artery calcification, but the underlying mechanisms remained largely unknown. Considering that CDKN2A/2B is a frequently reported site for DNA methylation, this study aimed to evaluate whether carotid artery calcification (CarAC is related to methylation levels of CDKN2A/2B in patients with ischemic stroke. Methods DNA methylation levels of CDKN2A/2B were measured in 322 ischemic stroke patients using peripheral blood leukocytes. Methylation levels of 36 CpG sites around promoter regions of CDKN2A/2B were examined with BiSulfite Amplicon Sequencing. CarAC was quantified with Agatston score based on results of computed tomography angiography. Generalized liner model was performed to explore the association between methylation levels and CarAC. Results Of the 322 analyzed patients, 187 (58.1% were classified as with and 135 (41.9% without evident CarAC. The average methylation levels of CDKN2B were higher in patents with CarAC than those without (5.7 vs 5.4, p = 0.001. After adjustment for potential confounders, methylation levels of CDKN2B were positively correlated with cube root transformed calcification scores (β = 0.591 ± 0.172, p = 0.001 in generalized liner model. A positive correlation was also detected between average methylation levels of CDKN2B and cube root transformed calcium volumes (β = 0.533 ± 0.160, p = 0.001. Conclusions DNA methylation of CDKN2B may play a potential role in artery calcification.

    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. The concept of human capital is more limited since it only conceives human qualities in relation to economic growth, whereas the concept of capabili ties puts emphasis on the expansion of human freedom to live the kind of life that people judge valuable. 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 Este trabalho parte da consideração do envelhecimento humano como experiência heterogênea. Busca pôr em diálogo o grupo de sala de espera, recorrendo ao construcionismo social, para descrevê-lo como prática discursiva. Problematizando essa modalidade de intervenção psicológica, nesse estudo objetivamos descrever o processo de produção de sentidos sobre o envelhecimento humano nesse contexto. Dez grupos de sala de espera, gravados e transcritos, foram pré-analisados favorecendo a escolha de um deles para análise extensiva. Essa análise apontou que, nesse processo conversacional, a vivência do envelhecimento como experiência individual vai sendo paulatinamente reconstruída pelos interlocutores como de natureza sócio-interacional, apontando para posições mais ativas na produção de qualidade de vida no envelhecimento. Assim, os participantes em co-autoria, falando de seus cotidianos, abrem possibilidades de novas descrições sobre si mesmos enquanto pessoas idosas, nesse contexto interativo.

Sin embargo, en los últimos años una serie de estudios han revelado la existencia de estos rasgos adaptativos en otros primates. Esto ha cuestionado seriamente la validez de muchos de las aproximaciones materialistas que parten de la premisa de que sólo lo que aparece en el registro arqueológico es factible de ser interpretado. En este artículo se pasa revista a las explicaciones gradualistas y puntuadas de la aparición del comportamiento humano, y se subraya la necesidad de enfocar el problema desde una consideración socioecológica.ABSTRACT: The traditional views on the evolution of human behavior have overemphasized some of the material aspects of culture, conceived as properly human. 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.

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. El desarrollo humano ha sido un nuevo paradigma y un cambio de referentes, pero también tiene mucho de re-descubrimiento de viejas palabras.

    Full Text Available Enzyme replacement therapy (ERT with elosulfase alfa is the only approved therapy in Japan for patients with Morquio A syndrome, a lysosomal storage disorder inherited in an autosomal recessive fashion. The experience with ERT in severely affected, non-ambulatory patients has not been reported in previous studies. This case report describes clinical evidence for the 1-year efficacy and safety of ERT with elosulfase alfa in a severely affected, non-ambulatory, 47-year-old patient with Morquio A syndrome who needs intensive respiratory management. ERT with elosulfase alfa was well tolerated in this patient. Because of the possibility of potential hypersensitivity adverse events, special attention is needed when using ERT in patients with respiratory disorders. However, under the appropriate management of specialists, the patient in this case report showed significant respiratory improvement after starting ERT, and abdominal bloating was improved by gas evacuation. In addition, the patient was able to lift up her arms, reach behind her back, and move her legs slightly, and she recovered her grip strength. Her hearing loss improved and she could hear without a hearing aid. This report shows that ERT with elosulfase alfa can be used with appropriate respiratory care in patients with severe respiratory dysfunction.

    The aim of the study was to analyze, by using the ALFA4Hearing model (At-a-Glance Labeling for Features of Apps for Hearing Health Care), a sample of apps over a wide range of services in the hearing health care (HHC) domain in order to take a first picture of the current scenario of apps for HHC. We tested 120 apps, and we characterized them by using the ALFA4Hearing model, which includes 29 features in 5 components (Promoters, Services, Implementation, Users, and Descriptive Information). We analyzed (a) the distribution of the 29 features in the sample, (b) the relationship between the Implementation features and the Services provided by the apps, and (c) the distribution of the 29 features in apps for professional use. The analysis of our sample of apps by means of the ALFA4Hearing model highlighted interesting trends and emerging challenges. Also, results suggested many potential opportunities for research and clinical practice, such as greater involvement of stakeholders, improved evidence base, higher technical quality, and usability. The ALFA4Hearing model is able to represent, at a glance, a large amount of information about apps for HHC, highlighting trends and challenges. It might be useful to HHC professionals as a basis for app characterization and informed decision making.

    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 The influence of vanadium dioxide VO2(B on thermal decomposition of ammonium perchlorate (AP has not been reported before. In this contribution, the effect of VO2(B nanobelts on the thermal decomposition of AP was investigated by the Thermo- Gravimetric Analysis and Differential Thermal Analysis (TG/DTA. VO2(B nanobelts were hydrothermally prepared using peroxovanadium (V complexes, ethanol and water as starting materials. The thermal decomposition temperatures of AP in the presence of I wt.%, 3 wt.% and 6 wt.% of as-obtained VO2<B nanobelts were reduced by 39 °C. 62 °C and 74 °C, respectively. The results indicated that VO2(B nanobelts had a great influence on the thermal decomposition temperature of AP Furthermore, the influence of the corresponding V2Os, which was obtained by thermal treatment of VO2(B nanobelts, on the thermal decomposition of AP was also investigated. The resufs showed that VO2(B nanobelts had a greater influence on the thermal decomposition temperature of AP than that of V2Os.

    Full Text Available The GRIN2B (glutamate receptor, ionotropic, N-methyl- d -aspartate 2B gene, located in the short arm of chromosome 12, encoding the NR2B subunit of the N-methyl-D-aspartate receptor, has recently been recognized to play an important role in corticogenesis and brain plasticity. Deletions in the short arm of chromosome 12 are rare. Hemizygous loss of function of the GRIN2B gene results in developmental delay, whereas gain of function leads to epilepsy, and infantile spasms in particular. In addition, GRIN2B variants have been associated with autism spectrum disorder and schizophrenia. Here the authors report a child with global developmental delay, autistic behavioural features, central hypotonia, dysmorphic features and isolated congenital anomalies of the fingers and toes, and a de novo heterozygous deletion in chromosome locus 12p13.2-p13.1, involving loss of several genes, including GRIN2B . This report and our review of the literature help clarify the distinct phenotypes associated with loss or gain of GRIN2B function.

    Full Text Available LPA signaling plays important roles during cell migration and proliferation in normal and pathological conditions. However, its role during sensory organ development remains unknown. Here we show a LPA receptor Lpar2b is expressed in the posterior lateral line primordium (pLLP and mechanosensory organs called neuromasts (NMs in zebrafish embryos. Lpar2b loss-of-function significantly reduces the number of NMs and hair cells in the posterior lateral line (pLL. Further analysis reveals that Lpar2b regulates the patterning and tissue size of the pLLP. Interestingly, we show that knocking down a Hippo effector Yap1 phenocopies the result of Lpar2b depletion, and Lpar2b regulates the phosphorylation and activity of Yap1 in the pLLP. Importantly, a phosphorylation-resistant Yap1 rescues pLLP size and NM number in Lpar2b-depleted embryos. Our results indicate Lpar2b controls primordium size and NM number by regulating Yap1 activity in the lateral line system.

  7. The RAB2B-GARIL5 Complex Promotes Cytosolic DNA-Induced Innate Immune Responses

    Full Text Available Cyclic GMP-AMP synthase (cGAS is a cytosolic DNA sensor that induces the IFN antiviral response. However, the regulatory mechanisms that mediate cGAS-triggered signaling have not been fully explored. Here, we show the involvement of a small GTPase, RAB2B, and its effector protein, Golgi-associated RAB2B interactor-like 5 (GARIL5, in the cGAS-mediated IFN response. RAB2B-deficiency affects the IFN response induced by cytosolic DNA. Consistent with this, RAB2B deficiency enhances replication of vaccinia virus, a DNA virus. After DNA stimulation, RAB2B colocalizes with stimulator of interferon genes (STING, the downstream signal mediator of cGAS, on the Golgi apparatus. The GTP-binding activity of RAB2B is required for its localization on the Golgi apparatus and for recruitment of GARIL5. GARIL5 deficiency also affects the IFN response induced by cytosolic DNA and enhances replication of vaccinia virus. These findings indicate that the RAB2B-GARIL5 complex promotes IFN responses against DNA viruses by regulating the cGAS-STING signaling axis.

    Histones are small highly conserved cationic proteins which bind DNA and remain confined in the nucleus. These histones are quite vulnerable to oxidizing and nitrating agents. Peroxynitrite is a powerful oxidant and nitrating agent present in the biological system. In this study, peroxynitrite-induced nitration and oxidation of H2B was assessed by various physicochemical techniques. The carbonyl content and dityrosine were markedly elevated in peroxynitrite-modified H2B histone as compared to the native histone. Cross-linking of H2B was evident on polyacrylamide gel electrophoresis. 3-Nitrotyrosine was present only in peroxynitrite-modified H2B revealed by HPLC. The results showed that peroxynitrite-mediated nitration and oxidation in H2B histone exhibited hyperchromicity, decrease of tyrosine fluorescence accompanied by increase in ANS-binding specific fluorescence, loss of β-sheet structure, appearance of new peak in FT-IR, increase in melting temperature and also loss of α-helix to produce a partially folded structure in comparison to intrinsically disordered structure of native H2B histone. We concluded that the H2B histone, a constituent of core histones, is highly sensitive to peroxynitrite and can adopt different structures under nitrosative and oxidative stress in order to protect the packaged DNA from the deleterious insult of peroxynitrite.

    Hypogonadotropic hypogonadism (HH) in men results in insufficient testicular function and deficiencies in testosterone and spermatogenesis. Combinations of human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) have been successful in the treatment of HH. Corifollitropin alfa is a long-acting FSH-analog with demonstrated action in women seeking infertility care. The aim of this study was to investigate the efficacy and safety of corifollitropin alfa combined with hCG to increase testicular volume and induce spermatogenesis in men with HH. This was a Phase III, multi-center, open-label, single-arm trial of corifollitropin alfa in azoospermic men aged 18 to 50 years with HH. After 16 weeks of pretreatment of 23 subjects with hCG alone, 18 subjects with normalized testosterone (T) levels who remained azoospermic entered the 52-week combined treatment phase with hCG twice-weekly and 150 μg corifollitropin alfa every other week. The increase in testicular volume (primary efficacy endpoint) and induction of spermatogenesis resulting in a sperm count ≥1 × 10 6 /mL (key secondary efficacy endpoint) during 52 weeks of combined treatment were assessed. Safety was evaluated by the presence of anti-corifollitropin alfa antibodies and the occurrence of adverse events (AEs). Mean (±SD) testicular volume increased from 8.6 (±6.09) mL to 17.8 (±8.93) mL (geometric mean fold increase, 2.30 [95% CI: 2.03, 2.62]); 14 (77.8%) subjects reached a sperm count ≥1 × 10 6 /mL. No subject developed confirmed anti-corifollitropin alfa antibodies during the trial. Treatment was generally well tolerated. Corifollitropin alfa 150 μg administrated every other week combined with twice-weekly hCG for 52 weeks increased testicular volume significantly, and induced spermatogenesis in >75% of men with HH who had remained azoospermic after hCG treatment alone.

    Individuals with congenital central hypoventilation syndrome have characteristic variants in the PHOX2B gene (primarily polyalanine expansion mutations). The PHOX2B gene acts as a transcriptional activator in the promotion of pan-neuronal differentiation in the autonomic nervous system during early embryologic development, with a primary role in the sympathetic noradrenergic phenotype in vertebrates. Because sympathetic innervation has been hypothesized to affect the development of dermatoglyphic pattern types, we hypothesized that individuals with PHOX2B-confirmed congenital central hypoventilation syndrome would have characteristic dermatoglyphic patterning and that the dermatoglyphic phenotype would be related to the disease-defining PHOX2B genotype. Dermatoglyphic pattern type frequency, left/right symmetry, and genotype/phenotype correlation were assessed for 33 individuals with PHOX2B-confirmed congenital central hypoventilation syndrome and compared with published control data. Dermatoglyphic pattern type frequencies were altered in congenital central hypoventilation syndrome cases versus controls. In particular, there was an increase of arches in females and ulnar loops in males, with the largest differences for the left hand and for individuals with both congenital central hypoventilation syndrome and Hirschsprung disease. Dissimilarity scores between the congenital central hypoventilation syndrome and congenital central hypoventilation syndrome + Hirschsprung disease cases were not significantly different, nor were dissimilarity scores between all of the female and all of the male cases. No significant association was found between the number of polyalanine repeats in the PHOX2B genotypic category and dermatoglyphic pattern frequencies in the congenital central hypoventilation syndrome study groups. These results represent the first report describing specific dermatoglyphic patterning in congenital central hypoventilation syndrome and suggest a

    Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated. In cancer patients with chemotherapy-related anemia receiving darbepoetin alfa, sucrosomial oral iron provides

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O debate sobre a segurança e eficácia da drotrecogina alfa (DrotAA encontra-se na ordem do dia, principalmente, em função dos resultados negativos observados em ensaios clínicos subseqüentes ao PROWESS e do impacto econômico no sistema de saúde relacionado ao custo elevado do fármaco. O objetivo deste estudo foi rever os principais estudos sobre a utilização da DrotAA em pacientes com sepse grave, com ênfase nas questões ligadas a sua eficácia e segurança. CONTEÚDO: Foram selecionados artigos sobre a utilização da DrotAA em pacientes com sepse publicados nos últimos dez anos no MedLine. Os seguintes unitermos foram utilizados: activated protein C; drotrecogin alfa; sepsis; septic shock; Xigris®. Estudos referenciados nos artigos selecionados na busca também foram utilizados. CONCLUSÕES: As taxas de letalidades e as complicações hemorrágicas associadas com o uso do fármaco foram maiores em grandes estudos observacionais do que aquelas descritas previamente nos ensaios clínicos. A luz dos resultados atualmente disponíveis, o uso da DrotAA deve ser reconsiderado até que novos ensaios clínicos possam subsidiar com informações adicionais sobre eficácia, segurança e na identificação dos subgrupos de pacientes com sepse grave que porventura possam ter benefício com o uso deste medicamento. A DrotAA deve servir de exemplo para que haja maior cautela com a rápida transposição de evidências ainda em construção para recomendações e diretrizes de tratamento de pacientes com sepse grave.BACKGROUND AND OBJECTIVES: The debate on efficacy and patient safety related to the use of drotrecogin alfa (DrotAA is timely, principally due to the negative results observed in clinical studies performed after the PROWESS study, and the economic cost-related impact of the drug on the healthcare system.

    Fabry disease (FD) is an X-linked lysosomal storage disorder resulting from the α-galactosidase A gene mutations. Enzyme-replacement-therapy (ERT) products for FD currently used include agalsidase alfa and agalsidase beta. There are many reports on efficacy and safety of ERT. However, most of the previous studies are done as a retrospective medical records analysis. The Japan Fabry Research - 002 (JFR-002) was a prospective observational clinical study of 36 ERT-naïve FD patients (14 men and 22 women) at baseline (BL) and after initiation of ERT with agalsidase alfa 0.2 mg/kg every two weeks, a median period 62.5 months. The parameters measured included globotriaosylceramide (Gb3), globotriaosylsphingosine (Lyso-Gb3), left ventricular mass index (LVMI), brain natriuretic peptide (BNP), high-sensitivity troponin I (hs-Trop I), estimated glomerular filtration rate (eGFR), and anti-agalsidase alfa IgG antibody formation. All parameters remained steady during ERT treatment period. BNP levels in 14 patients whose BL levels were within the normal range (<19.5 pg/mL) remained within the same range, while 22 patients whose BL levels were abnormally high (≥19.5 pg/mL) gradually showed decreased levels after start of ERT. Gb3 and Lyso-Gb3 levels remarkably decreased after the initiation of ERT and remained low. The JFR-002 suggests that agalsidase alfa is effective in maintaining organ function in FD patients, and that the incidence of infusion reactions related to the treatment with agalsidase alfa is low, indicating the good tolerability to this ERT. The JFR-002 was retrospectively registered at Japan Medical Association Center for Clinical Trials (Registration number: JMA-IIA00291 ) on May 19th, 2017.

Cada vez más los analistas del papel de los medios de comunicación en la sociedad y de la responsabilidad social de la informática también están llegando a conclusiones de este tipo, resaltando la importancia tanto de la alfabetización mediática como de la alfabetización en informática. Obviamente, este argumento nos lleva a analizar el planteamiento que los profesionales de la información se hacen de los cursos sobre alfabetización de información que actualmente imparten. Aunque existen muchos programas de alfabetización informacional que son muy completos, éstos, hasta ahora, se basan, en su mayor parte, en lo que los profesionales piensan que son las necesidades prácticas de los usuarios. Sin embargo, se puede interpretar que las declaraciones de tipo general como, por ejemplo, la Declaración de Praga “Hacia una Sociedad de la Alfabetización Informacional” del 2003 y la Proclamación de Alejandría del 2005 empiezan a apuntar hacia una justificación de las actividades de la alfabetización informacional basadas en los derechos humanos, en concreto en el artículo 19. El argumento es que si se parte de una perspectiva basada en los derechos humanos podemos llegar a una interpretación sólida de la alfabetización informacional que incluya la alfabetización mediática, la alfabetización en informática, la alfabetización en la web y, hasta cierto punto, la alfabetización cívica, desarrollando de este modo un modelo que responde a las necesidades humanas más que a las prioridades

    Multiple endocrine neoplasia type 2B (MEN2B) is a rare autosomal-dominant cancer syndrome characterized in part by metastatic medullary thyroid cancer (MTC) and pheochromocytoma. Cushing disease is a rare cause of endogenous hypercortisolism in children. We describe a 21-year-old African-American male who was diagnosed at age 10 with an ACTH-secreting pituitary microadenoma. At age 16 he developed medullary thyroid cancer and was found to have multiple endocrine neoplasia type 2B with the characteristic M918T mutation of the RET proto-oncogene. Following thyroidectomy, he was initiated on Vandetanib, a tyrosine kinase inhibitor, and has since had stable disease over the last 5 years. Our patient is the first individual with MEN2B to be described with Cushing disease. The RET oncogene may play a role in pituitary tumorigenesis; alternatively, the coexistence of these two entities may represent an extremely rare coincidence.

The M2B3 Reporting Standard (1) describes minimal mandatory and recommended contextual information for a marine microbial sample obtained in the epipelagic zone, (2) includes meaningful information for researchers in the oceanographic, biodiversity and molecular disciplines, and (3) can easily be adopted by any marine laboratory with minimum sampling resources. The M2B3 Service Standard defines a software interface through which these data can be discovered and explored in data repositories. The M2B3 Standards were developed by the European project Micro B3, funded under 7(th) Framework Programme "Ocean of Tomorrow", and were first used with the Ocean Sampling Day initiative. We believe that these standards have value in broader marine science.

    2014-01-01

    Full Text Available In the present work, a diffusion model was suggested to study the growth kinetics of Fe2B layers grown on the AISI 1045 steel by the pack-boriding treatment. The generated boride layers were analyzed by optical microscopy and X-ray diffraction analysis. The applied diffusion model is based on the principle of mass conservation at the (Fe2B/ substrate interface. It was used to estimate the boron diffusion coefficients of Fe2B in the temperature range of 1123-1273 K. A validation of the model was also made by comparing the experimental Fe2B layer thickness obtained at 1253 K for 5 h of treatment with the predicted value. Basing on our experimental results, the boron activation energy was estimated as 180 kJ mol-1 for the AISI 1045 steel.

    Full Text Available The VO2 (B was synthesized via a simple solvothermal route at 160oC in ethanol. The initial discharge capacity of VO2 (B anode, in saturated aqueous solution of LiNO3, was 177 mAh g-1 at a current rate of 50 mA g-1. After 50 cycles capacity fade was 4%, but from 20th-50th cycle no capacity drop was observed. The VO2 (B has shown very good cyclability at current rate of even 1000 mA g-1 with initial discharge capacity of 92 mAh g-1. The excellent electrochemical performance of VO2 (B was attributed to the stability of micro-nano structures to repeated intercalation /deintercalation process, very good electronic conductivity as well as the very low charge transfer resistance in the aqueous electrolyte.

    Addiction is a maladaptive pattern of behavior following repeated use of reinforcing drugs in predisposed individuals, leading to lifelong changes. Common among these changes are alterations of neurons releasing dopamine in the ventral and dorsal territories of the striatum. The serotonin 5-HT 2B receptor has been involved in various behaviors, including impulsivity, response to antidepressants, and response to psychostimulants, pointing toward putative interactions with the dopamine system. Despite these findings, it remains unknown whether 5-HT 2B receptors directly modulate dopaminergic activity and the possible mechanisms involved. To answer these questions, we investigated the contribution of 5-HT 2B receptors to cocaine-dependent behavioral responses. Male mice permanently lacking 5-HT 2B receptors, even restricted to dopamine neurons, developed heightened cocaine-induced locomotor responses. Retrograde tracing combined with single-cell mRNA amplification indicated that 5-HT 2B receptors are expressed by mesolimbic dopamine neurons. In vivo and ex vivo electrophysiological recordings showed that 5-HT 2B -receptor inactivation in dopamine neurons affects their neuronal activity and increases AMPA-mediated over NMDA-mediated excitatory synaptic currents. These changes are associated with lower ventral striatum dopamine activity and blunted cocaine self-administration. These data identify the 5-HT 2B receptor as a pharmacological intermediate and provide mechanistic insight into attenuated dopamine tone following exposure to drugs of abuse. SIGNIFICANCE STATEMENT Here we report that mice lacking 5-HT 2B receptors totally or exclusively in dopamine neurons exhibit heightened cocaine-induced locomotor responses. Despite the sensitized state of these mice, we found that associated changes include lower ventral striatum dopamine activity and lower cocaine operant self-administration. We described the selective expression of 5-HT 2B receptors in a subpopulation of

    Ichthyoses are a clinically and genetically heterogeneous group of genodermatoses associated with abnormal scaling of the skin over the whole body. Mutations in nine genes are known to cause non-syndromic forms of autosomal-recessive congenital ichthyosis (ARCI). However, not all genetic causes for ARCI have been discovered to date. Using whole-exome sequencing (WES) and multigene panel screening, we identified 6 ARCI-affected individuals from three unrelated families with mutations in Sulfotransferase family 2B member 1 (SULT2B1), showing their causative association with ARCI. Cytosolic sulfotransferases form a large family of enzymes that are involved in the synthesis and metabolism of several steroids in humans. We identified four distinct mutations including missense, nonsense, and splice site mutations. We demonstrated the loss of SULT2B1 expression at RNA and protein levels in keratinocytes from individuals with ARCI by functional analyses. Furthermore, we succeeded in reconstructing the morphologic skin alterations in a 3D organotypic tissue culture model with SULT2B1-deficient keratinocytes and fibroblasts. By thin layer chromatography (TLC) of extracts from these organotypic cultures, we could show the absence of cholesterol sulfate, the metabolite of SULT2B1, and an increased level of cholesterol, indicating a disturbed cholesterol metabolism of the skin upon loss-of-function mutation in SULT2B1. In conclusion, our study reveals an essential role for SULT2B1 in the proper development of healthy human skin. Mutation in SULT2B1 leads to an ARCI phenotype via increased proliferation of human keratinocytes, thickening of epithelial layers, and altered epidermal cholesterol metabolism.

    Full Text Available The advent of the internet has created numerous opportunities for B2B marketing professionals to enhance current marketing practices, including electronic relationships. However, the investigation of e-relationships and the factors that influence e-relationships in an internet environment is scant. Further, there appears to be no investigation of this phenomenon within the context of Greek B2B Medium-sized firms (MSF. Τhe research problem investigated in this research is: “Which drivers in B2B e-commerce use affect inter-firm relationships in medium-sized B2B firms?”. A framework for B2B e-commerce relationships in a changing and globalized environment was synthesised and integrated with the literature about relationship marketing to arrive at the following research issues: “How do relationship marketing drivers affect the management of B2B e-relationships?”. An explanatory quantitative research approach was used and quantitative data was collected from B2B firms in Greece, which represents a case of e-commerce progress during the last six years. Regarding social exchange, some important differences emerge where cooperation between B2B e-commerce firms is concerned. Suppliers engaged in electronic commerce are more committed and oriented to a long-term relationship than buyers, based on both previous and current experience with them. Confidence in the relationships, consistency and honesty with their obligations and the exchange of reliable, trustworthy information and advisory services between firms are important factors in the development and establishment of their e-relationships. The main contribution of this research is the development of a theoretical framework for e-relationships in medium-sized Β2Β firms. That framework is the first rigorously researched step towards understanding the importance of these powerful streams of relationship drivers in total, and the business activity of e-marketing and electronic relationships.

  18. Multiple endocrine neoplasias type 2B and RET proto-oncogene

    2012-03-01

    Full Text Available Abstract Multiple Endocrine Neoplasia type 2B (MEN 2B is an autosomal dominant complex oncologic neurocristopathy including medullary thyroid carcinoma, pheochromocytoma, gastrointestinal disorders, marphanoid face, and mucosal multiple ganglioneuromas. Medullary thyroid carcinoma is the major cause of mortality in MEN 2B syndrome, and it often appears during the first years of life. RET proto-oncogene germline activating mutations are causative for MEN 2B. The 95% of MEN 2B patients are associated with a point mutation in exon 16 (M918/T. A second point mutation at codon 883 has been found in 2%-3% of MEN 2B cases. RET proto-oncogene is also involved in different neoplastic and not neoplastic neurocristopathies. Other RET mutations cause MEN 2A syndrome, familial medullary thyroid carcinoma, or Hirschsprung's disease. RET gene expression is also involved in Neuroblastoma. The main diagnosis standards are the acetylcholinesterase study of rectal mucosa and the molecular analysis of RET. In our protocol the rectal biopsy is, therefore, the first approach. RET mutation detection offers the possibility to diagnose MEN 2B predisposition at a pre-clinical stage in familial cases, and to perform an early total prophylactic thyroidectomy. The surgical treatment of MEN 2B is total thyroidectomy with cervical limphadenectomy of the central compartment of the neck. When possible, this intervention should be performed with prophylactic aim before 1 year of age in patients with molecular genetic diagnosis. Recent advances into the mechanisms of RET proto-oncogene signaling and pathways of RET signal transduction in the development of MEN 2 and MTC will allow new treatment possibilities.

  19. Viroporin Activity of the Foot-and-Mouth Disease Virus Non-Structural 2B Protein.

    Directory of Open Access Journals (Sweden)

    Da Ao

    Full Text Available Viroporins are a family of low-molecular-weight hydrophobic transmembrane proteins that are encoded by various animal viruses. Viroporins form transmembrane pores in host cells via oligomerization, thereby destroying cellular homeostasis and inducing cytopathy for virus replication and virion release. Among the Picornaviridae family of viruses, the 2B protein encoded by enteroviruses is well understood, whereas the viroporin activity of the 2B protein encoded by the foot-and-mouth disease virus (FMDV has not yet been described. An analysis of the FMDV 2B protein domains by computer-aided programs conducted in this study revealed that this protein may contain two transmembrane regions. Further biochemical, biophysical and functional studies revealed that the protein possesses a number of features typical of a viroporin when it is overexpressed in bacterial and mammalian cells as well as in FMDV-infected cells. The protein was found to be mainly localized in the endoplasmic reticulum (ER, with both the N- and C-terminal domains stretched into the cytosol. It exhibited cytotoxicity in Escherichia coli, which attenuated 2B protein expression. The release of virions from cells infected with FMDV was inhibited by amantadine, a viroporin inhibitor. The 2B protein monomers interacted with each other to form both intracellular and extracellular oligomers. The Ca(2+ concentration in the cells increased, and the integrity of the cytoplasmic membrane was disrupted in cells that expressed the 2B protein. Moreover, the 2B protein induced intense autophagy in host cells. All of the results of this study demonstrate that the FMDV 2B protein has properties that are also found in other viroporins and may be involved in the infection mechanism of FMDV.

    Fluoxetine and other serotonin-specific re-uptake inhibitors (SSRIs) are generally thought to owe their therapeutic potency to inhibition of the serotonin transporter (SERT). However, research in our laboratory showed that it affects, with relatively high affinity the 5-HT2B receptor in cultured astrocytes; this finding was confirmed by independent observations showing that fluoxetine loses its ability to elicit SSRI-like responses in behavioral assays in mice in which the 5-HT2B receptor was...

    Abstract The now banned anorectic molecule, dexfenfluramine, promotes serotonin release through a serotonin transporter-dependent mechanism and has been widely prescribed for the treatment of obesity. Previous studies have identified that 5-HT2B receptors play important roles in dexfenfluramine-side effects, i.e. pulmonary hypertension, plasma serotonin level regulation, and valvulopathy. We thus investigated a putative contribution of 5-HT2B receptors in dexfenfluramine-dependent ...

    The rhythmic opening and tightly closing of cardiac valve leaflets are cardiac cyclic events imposing to blood a unidirectional course along the vascular tree. Drugs with 5-HT2B agonism properties can seriously compromise this biological function critical for hemodynamic efficiency as their intrinsic pro-fibrotic effects can, with time, make valvular coaptation blood regurgitant. Cardiac valve anatomy, physiology and pathology as well as 5-HT2B receptor properties (coupling, effects mediated, biased agonism) are briefly exposed. Approaches to unveil 5-HT2B receptor liability of drug candidates are detailed. In silico computational models can rapidly probe molecules for chemical signatures associated with 5-HT2B receptor affinity. In vitro radioligand competition assays allow quantifying receptor binding capacity (Ki, IC50), the pharmacological nature (agonism, antagonism) of which can be ascertained from cytosolic second messenger (inositol phosphates, Ca(++), MAPK2) changes. Potencies calculated from the latter data may exhibit variability as they are dependent upon the readout measured and the experimental conditions (e.g., receptor density level of cell material expressing human 5-HT2B receptors). The in vivo valvulopathy effects of 5-HT2B receptor agonists can be assessed by echocardiographic measurements and valve histology in rats chronically treated with the candidate drug. Finally, safety margins derived from from nonclinical and clinical data are evaluated in terms of the readout, usefulness and scientific reliability. The Safety Pharmacology toolbox for detecting possible 5-HT2B receptor agonism liabilities of candidate drugs requires meticulous optimization and validation of all its (in silico, in vitro and in vivo) components to perfect its human predictability power. In particular, since 5-HT2B receptor agonism is biased in nature, the most predictive readout(s) of valvular liability should be identified and prioritized in keeping with best scientific

    Multiple Endocrine Neoplasia Type 2B (MEN2B) is a cancer-predisposing syndrome that affects patients with germline RET mutations. The clinical spectrum of the syndrome includes medullary thyroid carcinoma (MTC) and pheochromocytoma. Currently, there is no satisfactory model recapitulating all the features of the disease especially at the level of stem cells. We generated induced pluripotent stem cells (iPSCs) from a patient with RET mutation at codon 918 who developed pheochromocytoma and MTC. These iPSC had normal karyotype, harboured the RET M918T mutation and expressed pluripotency hallmarks. A comprehensive pathological assessment of teratoma was performed after injection in immunodeficient mice. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

    We have analyzed the electronic populations of chemical bonds and atoms in the highly symmetric closo-carboranes 1,5-C 2 B 3 H 5 (I) and 1,6-C 2 B 4 H 6 (II). The overlap populations σ/sub XY/ are compared with the corresponding Mulliken indices. We note substantial nonadditivity of the populations σ/sub XY/ for closed three-center bonds BCB' and the closeness of the total overlap populations σ/sub t/ to its maximum value. We have established the localization of the natural MOs on the bonds CH, BH, and BCB', and for molecule I also on the CBC' bonds. The effects of conjugation of bonds in the closo-carborane polyhedron are apparent in the linear dependence of these MOs. The corresponding nonorthogonal hybrid AOs of carbon and boron are also linearly dependent. We have formulated the concept of unshared population of an atom

    Despite being a pleiotropic cytokine, the therapeutic potential of interferon α2b (IFNα2b) is debatable. Thus, the need for identifying predictive marker(s) for patients who are most likely to benefit from the treatment is pivotal for avoiding the exposure of nonresponsive patients to the toxicity of the treatment. To account for the attenuated efficacy of the drug, we have verified its dendritic cell (DC) maturating ability from monocytes of cervical cancer stage IIIB (CaCx-IIIB) patients. First, we evaluated the status of monocytes from CaCx-IIIB and healthy women by conducting flow cytometric studies of various activation markers and a cytokine analysis by enzyme-linked immunosorbent assay (ELISA) and flow cytometry. Immature DCs were then generated from these monocytes and matured with low-dose IFNα2b (1500 units/mL). A functional and phenotypic comparative analysis of these matured DCs was performed by flow cytometric, proliferative, cytotoxic, and enzyme-linked immunosorbent assays. Our study shows that monocytes isolated from CaCx-IIIB are impaired, and in vitro maturation with IFNα2b did not significantly improve the functional repertoire of DCs generated from these monocytes in comparison with healthy controls. This impairment of monocytes might be a plausible reason for the attenuated efficacy of this drug alone in treating CaCx-IIIB patients, and this imbalance of immune parameters associated with the stage of malignancy might be considered an effective marker to design a proper therapeutic regimen.

    Craniofacial defects that occur through gene mutation during development increase vulnerability to eustachian tube dysfunction. These defects can lead to an increased incidence of otitis media. We examined the effects of a mutation in the Sh3pxd2b gene (Sh3pxd2b(nee)) on the progression of otitis media and hearing impairment at various developmental stages. We found that all mice that had the Sh3pxd2b(nee) mutation went on to develop craniofacial dysmorphologies and subsequently otitis media, by as early as 11 days of age. We found noteworthy changes in cilia and goblet cells of the middle ear mucosa in Sh3pxd2b(nee) mutant mice using scanning electronic microscopy. By measuring craniofacial dimensions, we determined for the first time in an animal model that this mouse has altered eustachian tube morphology consistent with a more horizontal position of the eustachian tube. All mutants were found to have hearing impairment. Expression of TNF-α and TLR2, which correlates with inflammation in otitis media, was up-regulated in the ears of mutant mice when examined by immunohistochemistry and semi-quantitative RT-PCR. The mouse model with a mutation in the Sh3pxd2b gene (Sh3pxd2b(nee)) mirrors craniofacial dysmorphology and otitis media in humans.

    The functional importance of a peripheral pocket found in previously published X-ray crystal structures of CYP2B4 and CYP2B6 was probed using a biophysical approach. Introduction of tryptophan within the pocket of CYP2B4 at F202 or I241 leads to marked impairment of 7-ethoxy-4-(trifluoromethyl)coumarin (7-EFC) or 7-benzyloxyresorufin O-dealkylation efficiency; a similar substitution at F195, near the surface access to the pocket, does not affect these activities. The analogous CYP2B6 F202W mutant is inactive in the 7-EFC O-dealkylation assay. The stoichiometry of 7-EFC deethylation suggested that the decreased activity of F202W and I241W in CYP2B4 and lack of activity of F202W in CYP2B6 coincided with a sharp increase in the flux of reducing equivalents through the oxidase shunt to produce excess water. The results indicate that the chemical identity of residues within this peripheral pocket, but not at the mouth of the pocket, is important in substrate turnover and redox coupling, likely through effects on active site topology.

    Recent genome-wide association studies (GWASs) have identified 30 genetic loci that regulate blood pressure, increasing our understanding of the cause of hypertension. However, it has been difficult to define the causative genes at these loci due to a lack of functional analyses. In this study, we aimed to validate the candidate gene ATP2B1 in 12q21, variants near which have the strongest association with blood pressure in Asians and Europeans. ATP2B1 functions as a calcium pump to fine-tune calcium concentrations - necessary for repolarization following muscular contractions. We silenced Atp2b1 using an siRNA complex, injected into mouse tail veins. In treated mice, blood pressure rose and the mesenteric arteries increased in wall : lumen ratio. Moreover, the arteries showed enhanced myogenic responses to pressure, and contractile responses to phenylephrine increased compared with the control, suggesting that blood pressure is regulated by ATP2B1 through the contraction and dilation of the vessel, likely by controlling calcium concentrations in the resting state. These results support that ATP2B1 is the causative gene in the blood pressure-associated 12q21 locus and demonstrate that ATP2B1 expression in the vessel influences blood pressure.

    Full Text Available Product of the Itga2b gene, CD41 contributes to hematopoietic stem cell (HSC and megakaryocyte/platelet functions. CD41 expression marks the onset of definitive hematopoiesis in the embryo where it participates in regulating the numbers of multipotential progenitors. Key to platelet aggregation, CD41 expression also characterises their precursor, the megakaryocyte, and is specifically up regulated during megakaryopoiesis. Though phenotypically unique, megakaryocytes and HSC share numerous features, including key transcription factors, which could indicate common sub-regulatory networks. In these respects, Itga2b can serve as a paradigm to study features of both developmental-stage and HSC- versus megakaryocyte-specific regulations. By comparing different cellular contexts, we highlight a mechanism by which internal promoters participate in Itga2b regulation. A developmental process connects epigenetic regulation and promoter switching leading to CD41 expression in HSC. Interestingly, a similar process can be observed at the Mpl locus, which codes for another receptor that defines both HSC and megakaryocyte identities. Our study shows that Itga2b expression is controlled by lineage-specific networks and associates with H4K8ac in megakaryocyte or H3K27me3 in the multipotential hematopoietic cell line HPC7. Correlating with the decrease in H3K27me3 at the Itga2b Iocus, we find that following commitment to megakaryocyte differentiation, the H3K27 demethylase Jmjd3 up-regulation influences both Itga2b and Mpl expression.

    Full Text Available No sistema produtivo, meios de comunicação e nas instituições representativas do capital, é voz corrente que o Brasil vive uma vive uma crise de mão de obra qualificada. Embora os estudos sobre o trabalho tenham dificuldade em reconhecer o fato, inúmeras pesquisas confirmam que o país vive uma crise do capital humano. Esse trabalho apresenta um breve diagnóstico da crise e da estrutura de educação profissional, confirmando que problema encerra uma séria ameaça concreta à economia, desenvolvimento e ao processo de mobilidade social que ora se desenrola no Brasil.

  15. A ética ambiental dos direitos humanos

    2016-07-01

    Full Text Available Este trabalho visa abordar os modelos éticos de proteção jurídica do meio ambiente, desde a análise do biocentrismo ao antropocentrismo mitigado e intergeracional que fundamenta o conceito de sustentabilidade. Inicialmente é abordado a natureza jusfundamental e de direitos humanos do meio ambiente. Em seguida, são apresentados três modelos éticos de proteção do meio ambiente, que orientam as normativas de proteção ambiental, o não-antropocentrismo; antropocentrismo puro; e antropocentrismo mitigado. A partir disto, é analisado a evolução da vertente não antropocêntrica, passando pelo biocentrismo, pelo ecocentrismo, e pela ecologia profunda, até a um antropocentrismo, inicialmente puro, que é mitigado pelos aspectos intergeracionais, intrínsecos à natureza difusa do bem ambiental, como modelo atual vigente.

    Full Text Available RESUMEN El artículo presenta las diferentes alternativas cuando se consulta a los gestionadores, que participan en  el Mercado de Trabajo, para la consecución del recurso humano, con la finalidad de llenar las vacancias existentes en las empresas. Una segunda óptica apunta a visualizar la intervención del Estado, en el campo de la intermediación Laboral y la relación con los particulares que ejercen esta actividad. Finalmente, se plantean algunas tendencias sobre la manera como se desenvolverán esta clase de organizaciones a la Luz de la ley 50 de 1990 (Reforma laboral.

  20. O capital humano e o desenvolvimento econômico

    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
