A sampling campaign was carried out to assess the impact of the oil field activities on the concentrations of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) in ambient air at Umm Al-Aish oil field in northern Kuwait. Sixteen samples were collected from March 2014 to January 2015. The concentrations of ΣPCDD/Fs were relatively high (33.6-586 fg I-TEQ/m(3); median: 94.7 fg I-TEQ/m(3); 31.2 to 516 fg WHO-TEQ2005/m(3); median: 83...

INTRODUCTION: Different materials have been used for intervening in root perforations. These materials are often in contact with resin cements used for cementation of intraradicular retainers. The aim of this study was to evaluate the bond strength of self-adhesive resin cement to different materials used to treat root perforations (mineral trioxide aggregate [MTA], Portland cement [PORT], and glass ionomer cement [GIC]). METHODS: Four discs (10 × 1 mm) of each material (the MTA, PORT, and GIC groups) were embedded into polyvinyl chloride tubes using acrylic resin, ground, and polished until a flat surface was exposed...

BACKGROUND: Varus inclination of the uncemented stem is not necessarily a technical error. The proximal femoral anatomy of hips with a coxa vara deformity frequently predisposes varus inclination. METHODS: We reviewed a series of 200 patients undergoing primary uncemented THA with the Corail® hip system. Preoperative data were based on patient demographics, diagnosis, and radiographic information (preoperative templating-CT measurements), and compared postoperative alignment for each stem and type of stem used...

Galaxy mergers produce supermassive black hole binaries, which emit gravitational waves prior to their coalescence. We perform three-dimensional hydrodynamic simulations to study the tidal disruption of stars by such a binary in the final centuries of its life. We find that the gas stream of the stellar debris moves chaotically in the binary potential and forms accretion disks around both black holes. The accretion light curve is modulated over the binary orbital period owing to relativistic beaming. This periodic signal allows to detect the decay of the binary orbit due to gravitational wave emission by observing two tidal disruption events that are separated by more than a decade...

INTRODUCTION: In chronic inflammatory demyelinating polyradiculopathy (CIDP) the impairment of unmyelinated nerve fibers appears unexpected. The measurement of the electrically induced axon flare reflex is a clinical test to assess the peripheral C-nociceptor function. In this study we compared the flare area in patients suffering from chronic inflammatory demyelinating polyradiculopathy with healthy subjects. MATERIALS AND METHODS: We examined 18 patients fulfilling the criteria for CIDP (11 male, mean age 51...

A flaring X-ray source was found near the galaxy NGC 4697 (ref. 1). Two brief flares were seen, separated by four years. During each flare, the flux increased by a factor of 90 on a timescale of about one minute. There is no associated optical source at the position of the flares, but if the source was at the distance of NGC 4697, then the luminosities of the flares were greater than 10(39) erg per second. Here we report the results of a search of archival X-ray data for 70 nearby galaxies looking for similar flares...

Systemic lupus erythematosus (SLE) mostly affects young women of reproductive age group. SLE patients may conceive as any normal woman but complication may occur in these patients if the disease is active. Pregnancy in SLE may lead to 1. Aggravation of SLE (Lupus flare) 2. Pre-term delivery, intrauterine growth retardation and foetal loss (in presence of antiphospholipid antibodies) 3. Neonatal lupus especially in presence of Anti-Ro / La antibody. For a successful pregnancy, both from maternal and foetal aspects, disease should be quiescent for at least six months before the conception...

BACKGROUND: Herpesvirus infections often complicate the clinical course of patients with inflammatory bowel disease; however, invasive disease due to herpes simplex virus is distinctly uncommon. METHODS: We present a case of herpes simplex virus colitis and hepatitis, review all the previously published cases of herpes simplex virus colitis, and discuss common clinical features and outcomes. We also discuss the epidemiology, clinical manifestations, diagnosis, and management of herpes simplex virus infections, focusing specifically on patients with inflammatory bowel disease...

BRAF inhibitors (vemurafenib and dabrafenib) are nowadays commonly prescribed in BRAF-mutant metastatic melanoma and allow improvement of the overall survival and progression-free survival. They are, however, accompanied by many adverse effects which mainly affect the skin. We observed on computed tomographic scans in three different patients after 3 months of treatment, the onset of osteosclerotic lesions. In parallel, the computed tomographic scans showed a significant reduction in all of the previously identified metastases in all patients...

PURPOSE: Degarelix, a new GnRH receptor antagonist with demonstrated efficacy as first-line treatment in the management of high-risk prostate cancer, possesses some theoretical advantages over LHRH analogues in terms of avoiding "testosterone flare" and lower FSH levels. We set out to determine if pre-operative degarelix influenced surrogates of disease control in a randomized phase II study. EXPERIMENTAL DESIGN: 39 patients were randomly assigned to one of 3 different neo-adjuvant arms: degarelix only, degarelix/bicalutmaide, or LHRH agonist/bicalutamide...

BACKGROUND: Patients with rheumatoid arthritis (RA) spend a high proportion of their waking time in sedentary behaviour (SB) and have an increased risk of cardiovascular disease. Reduction of SB and increase in light intensity physical activity has been suggested as a means of improvement of health in patients with mobility problems. Short-term intervention studies have demonstrated that SB can be reduced by behavioural interventions in sedentary populations. To evaluate descriptively the feasibility of recruitment, randomisation, outcome assessments, retention and the acceptability of an individually tailored, theory-based behavioural intervention targeting reduction in daily sitting time in patients with RA...

Differential ion mobility spectrometry (DIMS) is capable of separating components of complex mixtures prior to mass spectrometric analysis, thereby increasing signal-to-noise and signal-to-background ratios on millisecond timescales. However, adding a DIMS device to the front end of a mass spectrometer can reduce the signal intensity of subsequent mass spectrometric analysis. This is a result, in part, of ions lost due to inefficient transfer of ions from the DIMS device through the aperture leading into the mass spectrometer...

BACKGROUND: A principal goal for the use of positron emission tomography (PET) in oncology is for real-time evaluation of tumor response to chemotherapy. Given that many contemporary anti-neoplastic agents function by impairing cellular proliferation, it is of interest to develop imaging modalities to monitor these pathways. Here we examined the effect of capecitabine on the uptake of thymidine analogs used with PET: 3'-deoxy-3'-[(18)F]fluorothymidine ((18)F-FLT), 1-(2'-deoxy-2'-[(18)F]fluoro-β-D-arabinofuranosyl) thymidine ((18)F-FMAU), and 1-(2'-deoxy-2'-[(18)F]fluoro-β-D-arabinofuranosyl) uracil ((18)F-FAU) in patients with advanced cancer...
