First Measurement of ν_{e} and ν_{μ} Interaction Cross Sections at the LHC with FASER's Emulsion Detector.

The first results of the study of high-energy electron neutrino (ν_{e}) and muon neutrino (ν_{μ}) charged-current interactions in the FASERν emulsion-tungsten detector of the FASER experiment at the LHC are presented. A 128.8 kg subset of the FASERν volume was analyzed after exposure to 9.

First Direct Observation of Collider Neutrinos with FASER at the LHC.

We report the first direct observation of neutrino interactions at a particle collider experiment. Neutrino candidate events are identified in a 13.6 TeV center-of-mass energy pp collision dataset of 35.

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC.

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6   6   6 m liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light.

OPERA tau neutrino charged current interactions.

The OPERA experiment was designed to discover the v appearance in a v beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors.

Final Results of the OPERA Experiment on ν_{τ} Appearance in the CNGS Neutrino Beam.

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.

An infant form of Alexander disease (a clinical case and literature review).

We present a case of the infant form of Alexander disease. The case uniqueness is that the patient's examination had been started at the preclinical stage and was continued during the manifestation and fastigium of disease. We present rare images obtained during neurosonography at the preclinical stage of the disease as well as the unique findings of MRI studies.

Oral isotretinoin and haemophilia A.

The effects of oral isotretinoin on the coagulation system are still not well known: some case reports describe thrombocytopenia or thrombocytosis, others present different effects on fibrinolysis. We report a case of severe acne treated with oral isotretinoin in a patient affected with haemophilia A. In this case, which differs from the only other case reported in the literature, oral isotretinoin did not appear to influence the haemophilic patient's need of factor VIII.

[A comparative assessment of the efficacy of different types of sealants for the prevention of caries in the permanent teeth of children in the oral hygiene system].

Three hermetics are assessed: chemically hardened Delton, light-hardened Estiseal, and composite Evikrol. The study was carried out in 126 children aged 6 years. The decrease of the increment of dental caries depends on the retention of hermetics on the occlusion surface of the teeth, and the efficacy of caries prevention in permanent teeth is much higher if hermetic sealing of fissures and fossae is combined with local fluorine prophylaxis and oral hygiene.

[The determination of oral care habits by surveying the children of Russia and Finland].

Questionnaires were distributed among 1187 children aged 7, 9 and 12 living in Moscow, St. Petersburg, Helsinki and Kuopio and dental examinations of these children were carried out. Children together with their parents answered the questions concerning tooth cleaning, consumption of sweets, parents' education.

[Specificity of action of extracellular proteases from Streptomyces spp].

The ability of an Actinomyces strain--Streptomyces spp. to produce extracellular proteases has been studied under varied cultivation conditions during the growth cycle. The activity of enzyme preparations precipitated from the culture liquid was determined with various substrates--gelatin, casein, fibrinogen, fibrin and collagen.

Background factors affecting dental caries in permanent teeth of Finnish and Soviet children.

The aim of this study was to analyze the association between some general background factors and caries experience in two groups of Finnish children (from Helsinki and Kuopio) and Soviet children (Moscow and Leningrad). A total of 1187 schoolchildren, ages seven, nine and twelve years, were examined and information about their health habits was gathered by questionnaire. Questions included use of sweets, cakes, soft drinks, sugar-sweetened coffee and tea, toothbrushing frequency and mother's education.

Surface-specific effect of a mineralizing agent on the permanent teeth and on periodontal status.

In a two-year clinical trial the surface-specific effect of a mineralizing agent on selected permanent teeth was evaluated as well as the effect of this agent on periodontal health in children. Compared with positive controls (Control group, n = 123, biweekly mouthrinsing with placebo and 0.2% NaF solutions), among children in the test group (n = 123, biweekly mouthrinsing with 2% Remodent and 0.

Effect of the mineralizing agent on the permanent teeth.

In a two-year pragmatic clinical trial, the effect of the mineralizing agent was evaluated on permanent teeth of the first eruption group among Finnish children (7-years old at the beginning of the study) with a low prevalence of DFS. In the test group (n = 123, biweekly mouthrinsing with a 2% solution of mineralizing agent and 0.2% NaF solution) the percentage reduction in increment of both EFDS and DFS was high, whereas in the control group (n = 123, biweekly mouthrinsing with placebo and 0.

[Effect of vitamin A on immunological status of patients with chronic pneumonia].

Effect of vitamin A on some patterns of specific and unspecific immunity was studied in patients with chronic pneumonia. The vitamin was administered into the patients during 7 days at a daily dose of 500,000 IU. Administration of vitamin A was found to stimulate several immunological patterns: content of T- and B lymphocytes in peripheral circulation as well as IgG and IgM blood serum were increased.
