Acoustic-Phonon Mediated Cyclotron Resonance Power Absorption in Zinc Oxide Free-Standing Nanostructure

157-162The phenomenon of cyclotron resonance power absorption when electrons are scattered by acoustic-phonons in ZnO free standing nanostructure (FSNS) is presented. The calculation is based on quantum mechanical perturbation technique. The dependence of power absorption on frequency, magnetic field, temperature and thickness of the FSNS is presented. FWHM or line-width of the resonance power absorption peaks is calculated using profile method and the influence of magnetic field, temperature and thickness of the FSNS is investigated, that the line-width is proportional to magnetic field whereas it is independent of temperature and thickness of FSNS. This theoretical analysis gives insights about magneto-optical properties of FSNS of ZnO which is essential for further experimental investigations

The PPE2 protein of Mycobacterium tuberculosis translocates to host nucleus and inhibits nitric oxide production

Mycobacterium tuberculosis, the bacterium that causes tuberculosis, is one of the most successful pathogens of humans. It has evolved several adaptive skills and evasion mechanisms to hijack the immunologically educated host to suit its intracellular lifestyle. Here, we show that one of the unique PPE family member proteins of M. tuberculosis, PPE2, can limit Nitric Oxide (NO) production by inhibiting inos gene transcription. PPE2 protein has a leucine zipper DNA-binding motif and a functional nuclear localization signal. PPE2 was translocated into the macrophage nucleus via the classical importin α/β pathway where it interacted with a GATA-binding site overlapping with the TATA box of inos promoter and inhibited NO production. PPE2 prolonged intracellular survival of a surrogate bacterium M. smegmatis in vitro as well as in vivo. This information is likely to improve our knowledge of host-pathogen interactions during M. tuberculosis infection which is crucial for designing effective anti-TB therapeutics

Risk factors for extubation failure in mechanically ventilated children in pediatric intensive care unit

Background: Mechanical ventilation is lifesaving in children with respiratory failure. However, its unnecessary prolongation once a child is capable of sustaining spontaneous effective ventilation is associated with significant complications. Objective: To identify the factors that lead to higher chance of extubation failure in mechanically ventilated children. Materials and Methods: A prospective, observational study was conducted over a period of 1 year. Children admitted to pediatric intensive care unit of a tertiary care hospital of Northern India aged 1 month–17 years, needing mechanical ventilation were included in the study. Predefined criteria were used to decide the timing of extubation. Relevant details were recorded to study various patient-related parameters and their association with extubation outcome. Results: Mean age of the study group was 50 months with a male:female ratio of 3:1. Extubation failure rate was 14.5%. Extubation failure was significantly higher in patients ventilated for >7 days (p=0.01), those with the pediatric risk of mortality score >10 at admission (p=0.009), in addition to peak inspiratory pressure >16 cm H2O (p=0.009) and FiO2 ≥0.35 (p=0.01) before extubation. Accidental extubation was also associated with higher extubation failure (p<0.001). Conclusion: Our study demonstrates that even though sicker patients requiring ventilation for longer duration are more prone to failed extubations, protocol based, and planned extubations lead to better extubation success

Pattern self-medication use of analgesics in Pune, Maharashtra, India

Background: Objective of current study was to find out self-medication pattern and to study awareness of ADRs to analgesics self-medication.Methods: II MBBS students collected the information of names of analgesics self-medication, dose, frequency of administration, health related problem for use of self-medication, source of information for the use of self-medication and information about ADRs. Students also educated the population about ADRs to analgesics with the help of ADR checklist.Results: Paracetamol was most commonly taken as self-medication and 39% persons reported ADRs with paracetamol.  Ibuprofen, diclofenac, paracetamol and aspirin were taken less than WHO DDD for joint pain. 79% study population was ignorant about ADRs to analgesics. Headache (37%) was common health related problem for self-medication of analgesics.   Conclusion: Information about problems with repeated use of analgesics like liver damage, analgesic nephropathy, gastric ulceration/bleeding should be provided by pharmacists either orally or with the help of leaflets or display board. Headache is common health related problem for the use of analgesics as self-medication. Pharmacists should take help of assistance tool to diagnosis headache like screener for migraine and guidelines for chronic headache for timely visit of self-medicating person to physician.

A multi-centric, single-blinded, randomized, parallel-group study to evaluate the effectiveness of nasoalveolar moulding treatment in non-syndromic patients with complete unilateral cleft lip, alveolus and palate (NAMUC study): a study protocol for a randomized controlled trial.

BACKGROUND Cleft lip and palate (CLP) are among the most common congenital anomaly that affects up to 33,000 newborns in India every year. Nasoalveolar moulding (NAM) is a non-surgical treatment performed between 0 and 6 months of age to reduce the cleft and improve nasal aesthetics prior to lip surgery. The NAM treatment has been a controversial treatment option with 51% of the cleft teams in Europe, 37% of teams in the USA and 25 of cleft teams in India adopting this methodology. This treatment adds to the already existing high burden of care for these patients. Furthermore, the supporting evidence for this technique is limited with no high-quality long-term clinical trials available on the effectiveness of this treatment. METHOD The NAMUC study is an investigator-initiated, multi-centre, single-blinded randomized controlled trial with a parallel group design. The study will compare the effectiveness of NAM treatment provided prior to lip surgery against the no-treatment control group in 274 patients with non-syndromic unilateral complete cleft lip and palate. The primary endpoint of the trial is the nasolabial aesthetics measured using the Asher McDade index at 5 years of age. The secondary outcomes include dentofacial development, speech, hearing, cost-effectiveness, quality of life, patient perception, feeding and intangible benefits. Randomization will be carried out via central online system and stratified based on cleft width, birth weight and clinical trial site. DISCUSSION We expect the results from this study on the effectiveness of treatment with NAM appliance in the long term along with the cost-effectiveness evaluation can eliminate the dilemma and differences in clinical care across the globe.

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
