    Get PDF
    Allergic rhinitis (AR) or hay fever is the most common symptomatic allergic disorder triggered by allergen and if it remains undiagnosed, can adversely impact the general well-being. The ailment is characterized by an exaggerated immune response to environmental triggers including pollen, moulds, ragweed, dirt mites, dust, etc. within the nasal mucosa, ultimately leading to gene environment interaction which elevate the IgE level in the nasal mucosa, and ultimately infection of the nasal cavity. The major signs and symptoms of AR include rhinorrhea, sneezing, eye itching, postnasal drip, cough, nasal obstruction, and fatigue due to nasal discomfort. Various studies reported 20-30% occurrence of the disease and majority of them are inclined towards allopathic medication for instant relief. Since these drugs lead to unenviable side effects in the long term, it is of utmost importance to search for alternative mode of medication with lower side-effects. The use of traditional medication in the form of various herbal plants and their mixture have proved to be effective in the management of symptoms for asthma and AR. Their efficiencies have been restrained successfully in various reports. It has been proven that herbal medicines are safe to use and thus have rendered a vast contribution to the treatment of allergic rhinitis. Hence, the present review is aimed to discuss the efficacy and protection provided by diverse herbal drugs in the management of AR

    Idiopathic inflammatory bowel disease is quite common, with ulcerative colitis and Crohn's disease being the most common forms. Due to its high receptor affinity and quick diversion, the anti-inflammatory effects of the glucocorticoid budesonide are limited, but it is nevertheless useful in some situations. A unique BUD nano-sponges was developed by employing quasi-solvent diffusion and Eudragit S-100 as the polymer to address the problem of low efficacy and accessibility. Material and Methods: Drug release profile and percentage of drug entrapment in BUD Nano sponges were also measured and analyzed. Clinical activity score, colon/body weight ratio, and macroscopic ulceration activity were among the criteria used in an in vivo investigation of the formulation in male Wistar rats. Finally, histological investigation was done on colon tissue samples. Results: When compared to other BUD formulations on the market, this one performed exceptionally well, suggesting that the designed nanosponges are highly effective. The Wistar rats' clinical activity score was reduced when treated with the formed nanosponges. When compared to the placebo group, those who took this supplement saw a dramatic decrease in their colon weight ratio. Nanosponge colon histology revealed healthy colon anatomy and architecture. Conclusion: The findings of this study have substantiated the efficacy of BUD nano-sponges as innovative carriers in the treatment of inflammatory bowel diseas

    Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

    Get PDF
    A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

    MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

    Get PDF
    Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

    The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

    Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| &lt; 0.03 at 95% confidence level.

    A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

    Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

    The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe
