    Abstract Objective: This study sought to compare the effectiveness of the 3 most commonly prescribed maintenance medications in the United States indicated for the treatment of opioid dependence in reducing illicit drug use and retaining patients in treatment.
    Method: Data were abstracted from electronic medical records for 3,233 patients admitted to 34 maintenance treatment facilities located throughout the United States during the period of July 1, 2012, through July 1, 2013. Patients were grouped into 1 of 3 medication categories based on their selection at intake (methadone [n = 2,738; M dosage = 64.64 mg/d, SD = 25.58], Suboxone [n = 102; M dosage = 9.75 mg/d, SD = 4.04], or Subutex [n = 393; M dosage = 12.21 mg/d, SD = 5.31]) and were studied through retrospective chart review for 6 months or until treatment discharge. Two measures of patient retention in treatment and urinalysis drug screen (UDS) findings for both opioids and various nonopioid substances comprised the study outcomes.
    Results: The average length of stay (LOS) in terms of days in treatment for the methadone group (M = 169.86, SE = 5.02) was significantly longer than both the Subutex (M = 69.34, SE = 23.43) and Suboxone (M = 119.35, SE = 20.82) groups. The Suboxone group evinced a significantly longer average LOS relative to the Subutex group. After adjustment for relevant covariates, patients maintained on methadone were 3.73 times (95% confidence interval [CI]= 2.82-4.92) and 2.48 times (95% CI = 1.57-3.92) more likely to be retained in treatment at 6 months than patients prescribed Subutex and Suboxone, respectively. The 6-month prevalence rates of positive UDS findings for both opioids and nonopioid substances were similar across medication groups.
    Conclusions: Comparable rates of illicit drug use at 6 months may be expected irrespective of maintenance medication, while increased retention may be expected for patients maintained on methadone relative to those maintained on Suboxone or Subutex.

    Abstract This study sought to determine whether select pretreatment demographic and in-treatment clinical variables predict premature treatment discharge at 6 and 12 months among patients receiving methadone maintenance treatment (MMT). Data were abstracted from electronic medical records for 1,644 patients with an average age of 34.7 years (SD = 11.06) admitted to 26 MMT programs located throughout the United States from 2009 to 2011. Patients were studied through retrospective chart review for 12 months or until treatment discharge. Premature discharge at 6- and 12-month intervals were the dependent variables, analyzed in logistic regressions. Clinical predictor variables included average methadone dosage (mg/d) and urinalysis drug screen (UDS) findings for opioids and various nonopioid substances at intake and 6 months. Pretreatment demographic variables included gender, race/ethnicity, employment status, marital status, payment method, and age at admission. UDS findings positive (UDS+) for cocaine at intake and 6 months were found to be independent predictors of premature discharge at 12 months. UDS+ for opioids at 6 months was also an independent predictor of premature discharge at 12 months. Higher average daily methadone dosages were found to predict retention at both 6 and 12 months. Significant demographic predictors of premature discharge at 6 months included Hispanic ethnicity, unemployment, and marital status. At 12 months, male gender, younger age, and self-pay were found to predict premature discharge. Select demographic characteristics may be less important as predictors of outcome after patients have been in treatment beyond a minimum period of time, while others may become more important later on in treatment.

    Abstract Research objective: To estimate cytogenetic effect of dentures on the condition of buccal epithelium by means of the micronuclear test. Materials and methods: For this test the most convenient object of the research is nonkeratinized stratified epithelium which has been taken from 24 patients before prosthetics. Statistical data processing has been done by means of a package of statistical programs «Stadia». Results: The increase in frequency of occurrence of cells with micronuclei in buccal epithelium in patients after the prosthetics that testifies to stability disturbance of genetic material in the studied cells. Influence of fillings and dentures has been revealed. Conclusion: It allows to apply safe materials in stomatology, having reduced their side effects on an organism as a whole

    Abstract We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A dataset of proton-proton collisions at sqrt[s]=13.6  TeV collected by SND@LHC in 2022 is used, corresponding to an integrated luminosity of 36.8  fb^{-1}. The search is based on information from the active electronic components of the SND@LHC detector, which covers the pseudorapidity region of 7.2<η<8.4, inaccessible to the other experiments at the collider. Muon neutrino candidates are identified through their charged-current interaction topology, with a track propagating through the entire length of the muon detector. After selection cuts, 8 ν_{μ} interaction candidate events remain with an estimated background of 0.086 events, yielding a significance of about 7 standard deviations for the observed ν_{μ} signal.

    Abstract The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

    Title translation Some peculiarities of the kinetics of DNA structural transition after thermal jump registered by hyperchromic effect.
    Abstract Structural transition of DNA is characterized by complex optical kinetic curve. The kinetic version of Felsenfeld's method is used for estimation of concentrations of "denatured" AT- and GC-base pairs in DNA molecules, and the rate constants of the accumulation of "denatured" AT as well as GC pairs have been estimated. The possible interpretation of the kinetic data obtained may be done by assumption that the fast stage of the process reflects the accumulation of the "denatured" AT pairs, which is due to the melting of AT-rich regions in the DNA molecules, whereas the slow stage of the process is limited by the melting of GC-rich regions. In contrast to the fast stage, slow stage takes place at conditions, when unwinded AT-rich regions (loops) may exist in DNA molecules and cause the delay in the process of denaturation.

    Abstract The OPERA experiment was designed to search for ν_{μ}→ν_{τ} oscillations in appearance mode, i.e., by detecting the τ leptons produced in charged current ν_{τ} interactions. The experiment took data from 2008 to 2012 in the CERN Neutrinos to Gran Sasso beam. The observation of the ν_{μ}→ν_{τ} appearance, achieved with four candidate events in a subsample of the data, was previously reported. In this Letter, a fifth ν_{τ} candidate event, found in an enlarged data sample, is described. Together with a further reduction of the expected background, the candidate events detected so far allow us to assess the discovery of ν_{μ}→ν_{τ} oscillations in appearance mode with a significance larger than 5σ.
