    GENERIC DRUG: PRESCRIBER’S PERSPECTIVE

    Objective: Knowledge of doctors and their understanding of generic drugs could facilitate in recognizing potential barriers to larger generic medicine prescriptions. Hence, the primary objective of this study was focused to explore knowledge, attitude, and practice (KAP) of doctors toward generic medicines. Methods: It is a cross-sectional questionnaire-based study. The study participants are the doctors working in the hospital during the study period (2016–2017). The questionnaire designed for this study comprised of thirty-five questions related to the knowledge, attitude, and practice (KAP) of generic medicine and about demographic details of the participants. Results: A total of 86 questionnaires were distributed among the health care professionals and the response rate is 37%. The majority of doctors who participated in this survey perceived that generic medicine is effective, safe and need to have the same active component, dose and bioequivalent as the brand name medicines. Most of the doctors (72%) were of the view that generic drugs were manufactured in poor quality than branded medicines. More than three-quarters of doctors (78%) prescribed generic drugs. Conclusion: Majority of the participants had an honest angle about the efficaciousness and safety of generic and though they sometimes prescribe generic medicine, however a high range of doctors (72%) were of the opinion that generic was of poorer quality than brand medicine. To have a better understanding of the generic drug, the doctor must be well informed about the generics during their academic career resulting in savings to healthcare budgets

    Role of trans-Planckian modes in cosmology

    Motivated by the old trans-Planckian (TP) problem of inflationary cosmology, it has been conjectured that any consistent effective field theory should keep TP modes `hidden' behind the Hubble horizon, so as to prevent them from turning classical and thereby affecting macroscopic observations. In this paper we present two arguments against the Hubble horizon being a scale of singular significance as has been put forward in the TP Censorship Conjecture (TCC). First, refinements of TCC are presented that allow for the TP modes to grow beyond the horizon while still keeping the de-Sitter conjecture valid. Second, we show that TP modes can turn classical even well within the Hubble horizon, which, as such, negates this rationale behind keeping them from crossing it. The role of TP modes is known to be less of a problem in warm inflation, because fluctuations start out usually as classical. This allows warm inflation to be more resilient to the TP problem compared to cold inflation. To understand how robust this is, we identity limits where quantum modes can affect the primordial power spectrum in one specific case.Comment: 33 pages, comments welcome; v2: References updated, matches published versio

    Fermentation, Isolation, Structure, and antidiabetic activity of NFAT-133 produced by Streptomyces strain PM0324667

    Type-2 diabetes is mediated by defects in either insulin secretion or insulin action. In an effort to identify extracts that may stimulate glucose uptake, similar to insulin, a high throughput-screening assay for measuring glucose uptake in skeletal muscle cells was established. During the screening studies to discover novel antidiabetic compounds from microbial resources a Streptomyces strain PM0324667 (MTCC 5543, the Strain accession number at Institute of Microbial Technology, Chandigarh, India), an isolate from arid soil was identified which expressed a secondary metabolite that induced glucose uptake in L6 skeletal muscle cells. By employing bioactivity guided fractionation techniques, a tri-substituted simple aromatic compound with anti-diabetic potential was isolated. It was characterized based on MS and 2D NMR spectral data and identified as NFAT-133 which is a known immunosuppressive agent that inhibits NFAT-dependent transcription in vitro. Our investigations revealed the antidiabetic potential of NFAT-133. The compound induced glucose uptake in differentiated L6 myotubes with an EC50 of 6.3 ± 1.8 μM without activating the peroxisome proliferator-activated receptor-γ. Further, NFAT-133 was also efficacious in vivo in diabetic animals and reduced systemic glucose levels. Thus it is a potential lead compound which can be considered for development as a therapeutic for the treatment of type-2 diabetes. We have reported herewith the isolation of the producer microbe, fermentation, purification, in vitro, and in vivo antidiabetic activity of the compound

    This Letter reports a search for charge-parity (CP) symmetry violating non-standard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from νμ(νˉμ)νμ(νˉμ)\nu_{\mu}(\bar{\nu}_{\mu})\rightarrow\nu_{\mu}(\bar{\nu}_{\mu}) and νμ(νˉμ)νe(νˉe)\nu_{\mu}(\bar{\nu}_{\mu})\rightarrow\nu_{e}(\bar{\nu}_{e}) oscillation channels are used to measure the effect of the NSI parameters εeμ\varepsilon_{e\mu} and εeτ\varepsilon_{e\tau}. With 90% C.L. the magnitudes of the NSI couplings are constrained to be εeμ0.3|\varepsilon_{e\mu}| \, \lesssim 0.3 and εeτ0.4|\varepsilon_{e\tau}| \, \lesssim 0.4. A degeneracy at εeτ1.8|\varepsilon_{e\tau}| \, \approx 1.8 is reported, and we observe that the presence of NSI limits sensitivity to the standard CP phase δCP\delta_{\tiny\text{CP}}

    Measurement of the νe -Nucleus Charged-Current Double-Differential Cross Section at «eν »=2.4 GeV Using NOvA

    Get PDF
    The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×1020 protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃17% systematic rather than the ≃7.4% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q2 (squared four-momentum transfer) and energy, in the range 1 GeV≤Eν<6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs Q2

    The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10208.02\times10^{20} protons-on-target (POT) in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by \simeq 17\% systematic rather than the \simeq 7.4\% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q2Q^{2} (squared four-momentum transfer) and energy, in the range 1 GeV Eν< \leq E_{\nu} < 6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs. Q2Q^{2}
