Search for monotop signatures in proton-proton collisions at √s=8 TeV.

Results are presented from a search for new decaying massive particles whose presence is inferred from an imbalance in transverse momentum and which are produced in association with a single top quark that decays into a bottom quark and two light quarks. The measurement is performed using 19.7  fb^{-1} of data from proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC.

Unusual presentation of pediatric acute sphenoid sinusitis.

Background: Sphenoid sinus lesions are rare entities, occurring in 2 - 3% out of all paranasal sinus lesions. Isolated oculomotor nerve palsy due to acute sphenoid sinusitis is very rare, with only few cases reported in literature.

Methods: Retrospective report about a case of isolated acute sphenoid sinusitis in a child with a left-sided third cranial nerve paralysis as the only sign at presentation.

Lateral neck recurrence from papillary thyroid carcinoma: Predictive factors and prognostic significance.

Objectives/hypothesis: The aim of this study was to identify any possible predictive factors of lateral neck recurrence in patients with papillary thyroid carcinoma with no ultrasonographic and/or cytological evidence of lymph node metastasis at time of diagnosis. The influence of lateral neck recurrence on survival was also investigated.

Study Design: Observational retrospective study.

Successful cochlear implantation in two profoundly deafened patients with neurofibromatosis type 1: further evidence to support a cochlear site of lesion.

Objective: To investigate the usefulness of cochlear implantation and to examine the evidence for a cochlear or retrocochlear site of lesion for deafness in Neurofibromatosis Type 1 (NF1).

Patients: Two profoundly deafened NF1 patients who underwent cochlear implantation.

Interventions: Preoperative electrophysiologic and audiologic evaluation including pure-tone audiometry, auditory brainstem response, speech audiometry, otoacoustic emission, and promontory stimulation test.

Gas-surface interactions using accommodation coefficients for a dilute and a dense gas in a micro- or nanochannel: heat flux predictions using combined molecular dynamics and Monte Carlo techniques.

The influence of gas-surface interactions of a dilute gas confined between two parallel walls on the heat flux predictions is investigated using a combined Monte Carlo (MC) and molecular dynamics (MD) approach. The accommodation coefficients are computed from the temperature of incident and reflected molecules in molecular dynamics and used as effective coefficients in Maxwell-like boundary conditions in Monte Carlo simulations. Hydrophobic and hydrophilic wall interactions are studied, and the effect of the gas-surface interaction potential on the heat flux and other characteristic parameters like density and temperature is shown.

Measurement of the Bs(0)→μ+ μ- branching fraction and search for B(0)→μ+ μ- with the CMS experiment.

Results are presented from a search for the rare decays Bs(0)→μ+ μ- and B(0)→μ+ μ- in pp collisions at sqrt[s]=7 and 8 TeV, with data samples corresponding to integrated luminosities of 5 and 20  fb(-1), respectively, collected by the CMS experiment at the LHC. An unbinned maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction B(Bs(0)→μ+ μ-)=(3.0(-0.

Nitric oxide regulates BAFF expression and T cell-independent antibody responses.

Whereas NO is known to regulate T cell responses, its role in regulating B cell responses remains unclear. Previous studies suggested that inducible NO synthase 2 (NOS2/iNOS) is required for normal IgA Ab responses but inhibits antiviral IgG2a Ab responses. In this study we used NOS2(-/-) mice to determine the role of NO in T cell-dependent and T cell-independent (TI)-2 Ab responses.

Necrotizing fasciitis of the neck: considerations about two cases.

Background And Aim Of The Work: Necrotizing fasciitis is a rapidly progressing life-threatening infection of the deep fat and fascial layers, which rarely occurs in the neck. The aim of the paper is to report the management of this rare condition, pointing out the role of multimodality in achieving the cure of the patient.

Methods: We report our experience regarding the management of two cases of necrotizing fasciitis of the neck successfully treated with surgical and medical treatment.
