Background: Glutamate excitotoxicity might contribute to the pathophysiology of amyotrophic lateral sclerosis. In animal models, decreased excitatory aminoacid transporter 2 (EAAT2) overexpression delays disease onset and prolongs survival, and ceftriaxone increases EAAT2 activity. We aimed to assess the safety and efficacy of ceftriaxone for amyotrophic lateral sclerosis in a combined phase 1, 2, and 3 clinical trial. Methods: This three-stage randomised, double-blind, placebo-controlled study was done at 59 clinical sites in the USA and Canada between Sept 4, 2006, and July 30, 2012. Eligible adult patients had amyotrophic lateral sclerosis, a vital capacity of more than 60% of that predicted for age and height, and symptom duration of less than 3 years. In stages 1 (pharmacokinetics) and 2 (safety), participants were randomly allocated (2:1) to ceftriaxone (2 g or 4 g per day) or placebo. In stage 3 (efficacy), participants assigned to ceftriaxone in stage 2 received 4 g ceftriaxone, participants assigned to placebo in stage 2 received placebo, and new participants were randomly assigned (2:1) to 4 g ceftriaxone or placebo. Participants, family members, and site staff were masked to treatment assignment. Randomisation was done by a computerised randomisation sequence with permuted blocks of 3. Participants received 2 g ceftriaxone or placebo twice daily through a central venous catheter administered at home by a trained caregiver. To minimise biliary side-effects, participants assigned to ceftriaxone also received 300 mg ursodeoxycholic acid twice daily and those assigned to placebo received matched placebo capsules. The coprimary efficacy outcomes were survival and functional decline, measured as the slope of Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) scores. Analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00349622. Findings: Stage 3 included 66 participants from stages 1 and 2 and 448 new participants. In total, 340 participants were randomly allocated to ceftriaxone and 173 to placebo. During stages 1 and 2, mean ALSFRS-R declined more slowly in participants who received 4 g ceftriaxone than in those on placebo (difference 0·51 units per month, 95% CI 0·02 to 1·00; p=0·0416), but in stage 3 functional decline between the treatment groups did not differ (0·09, -0·06 to 0·24; p=0·2370). No significant differences in survival between the groups were recorded in stage 3 (HR 0·90, 95% CI 0·71 to 1·15; p=0·4146). Gastrointestinal adverse events and hepatobiliary adverse events were more common in the ceftriaxone group than in the placebo group (gastrointestinal, 245 of 340 [72%] ceftriaxone vs 97 of 173 [56%] placebo, p=0·0004; hepatobiliary, 211 [62%] vs 19 [11%], p<0·0001). Significantly more participants who received ceftriaxone had serious hepatobiliary serious adverse events (41 participants [12%]) than did those who received placebo (0 participants). Interpretation: Despite promising stage 2 data, stage 3 of this trial of ceftriaxone in amyotrophic lateral sclerosis did not show clinical efficacy. The adaptive design allowed for seamless transition from one phase to another, and central venous catheter use in the home setting was shown to be feasible.

Dry deposition of speciated mercury, i.e., gaseous oxidized mercury (GOM), particulate-bound mercury (PBM), and gaseous elemental mercury (GEM), was estimated for the year 2008-2009 at 19 monitoring locations in eastern and central North America. Dry deposition estimates were obtained by combining monitored two-to four-hourly speciated ambient concentrations with modeled hourly dry deposition velocities (V d) calculated using forecasted meteorology. Annual dry deposition of GOM+PBM was estimated to be in the range of 0.4 to 8.1 μ mg -2 at these locations with GOM deposition being mostly five to ten times higher than PBM deposition, due to their different modeled V d values. Net annual GEM dry deposition was estimated to be in the range of 5 to 26 μ mg -2 at 18 sites and 33 μ mg -2 at one site. The estimated dry deposition agrees very well with limited surrogate-surface dry deposition measurements of GOM and PBM, and also agrees with litterfall mercury measurements conducted at multiple locations in eastern and central North America. This study suggests that GEM contributes much more than GOM+PBM to the total dry deposition at the majority of the sites considered here; the only exception is at locations close to significant point sources where GEM and GOM+PBM contribute equally to the total dry deposition. The relative magnitude of the speciated dry deposition and their good comparisons with litterfall deposition suggest that mercury in litterfall originates primarily from GEM, which is consistent with the limited number of previous field studies. The study also supports previous analyses suggesting that total dry deposition of mercury is equal to, if not more important than, wet deposition of mercury on a regional scale in eastern North America. © 2012 Author(s).

The objective of this paper is to provide a methodology for determining the degree of partial blending in high RAP mixtures. When RAP is mixed with virgin aggregates and virgin binder, partial blending of RAP binder occurs in the hot mix asphalt. Agencies limit the amount of RAP because the degree of blending between the RAP and the virgin materials is not known. The methodology provides a systematic approach for determining the degree of partial blending in the RAP mixture. The ability to accurately determine the degree of partial blending will help in determining the virgin binder content to be added in the mixture. The degree of partial blending measured from this procedure for 25% RAP by weight of aggregates with PG 70-28 and 35% RAP by weight of aggregates with PG 58-28 are 70% and 96% respectively. © 2010 Elsevier Ltd.

Estrogen Receptor α (ERα) and Estrogen Receptor β (ERβ) are steroid nuclear receptors that transduce estrogen signaling to control diverse physiological processes linked to reproduction, bone remodeling, behavior, immune response and endocrine-related diseases. In order to differentiate between ERα and ERβ mediated effects in vivo, ER subtype selective biomarkers are essential. We utilized ERα knockout (AERKO) and ERβ knockout (BERKO) mouse liver RNA and genome wide profiling to identify novel ERα selective serum biomarker candidates. Results from the gene array experiments were validated using real-time RT-PCR and subsequent ELISA's to demonstrate changes in serum proteins. Here we present data that Lipopolysacharide Binding Protein (LBP) is a novel liver-derived ERα selective biomarker that can be measured in serum. © 2012 Informa UK, Ltd.

Background: The purpose of this work was to study the demographics and survival of patients diagnosed with sinonasal adenocarcinoma (SNAC) within the time period of 1973 to 2009 using the Surveillance, Epidemiology, and End Result (SEER) database. Methods: A retrospective cohort study using the U.S. National Cancer Institute's SEER registry was performed to study the demographics and survival for SNAC from 1973 to 2009. Analysis was conducted based on race, gender, and stage. Results: In total, 1270 cases of SNAC were analyzed for demographics and survival. Males accounted for 51.6% of cases, while females accounted for 48.4% of cases, amounting to a male to female ratio of 1.06:1.00. Disease specific survival at 5, 10, 15, and 20 years was 65.2%, 50.9%, 40.9%, and 36.5%, respectively. When analyzed by gender, females had higher survival than males, although this difference was not statistically significant. When analyzed by race, the category of other, which encompasses American Indian, Asian, Hispanic, and unknown or unspecified race, was shown to have the best survival, followed by whites and blacks, respectively. Conclusion: SNAC is a rare tumor classically associated with occupational exposure and carries a variable prognosis. This is the first dedicated large-scale, retrospective analysis of a North American SNAC population. SNAC appears to affect both males and females equally and predominantly affects whites. Patients categorized as other had significantly better survival outcomes, while gender appeared to have no significant effect on survival. © 2014 ARS-AAOA, LLC.

The goal of this study was to perform an in vitro evaluation of the Spectra, a new caries detector that uses light-induced fluorescence of healthy tooth structure and bacterial pigments to optically detect caries. The Spectra generates a storable color map image of examined tooth surfaces which shows areas of enamel and dentin caries. In this study, Spectra readings of occlusal surfaces were compared to clinical, radiographic, and histological assessments of caries.Two examiners evaluated 41 extracted molars. The teeth were radiographed and then visually assessed. The International Caries Detection and Assessment System (ICDAS) was used to classify the extent of caries. The teeth were then sectioned and assigned a histological score based on the extension of caries into enamel or dentin.Teeth lacking radiographic caries had a mean Spectra reading of 1.5. Teeth having radiographic caries had a mean Spectra reading of 2.0. This difference was statistically significant. In general, higher ICDAS scores were associated with higher Spectra readings. Teeth with histologically evident deep dentin caries had significantly higher Spectra readings than intact teeth or teeth with superficial enamel demineralization. Spectra assessment of occlusal caries agrees with clinical and radiographic methods.Spectra images illustrate the full spectrum of caries severity, from enamel demineralization to dentin decay. The Spectra is a promising technology for the diagnosis and for monitoring the progression of occlusal caries.

Gout is the most common inflammatory arthritis in humans. Gout treatment includes rapid initiation of anti-inflammatory medications for acute attacks and chronically treating with urate lowering drugs as well as chronic anti-inflammatory prophylaxis. Areas covered: This review aims to provide an overview and discussion of the safety concerns of current treatment options available for gout. Expert opinion: Gout is a curable disease with appropriate treatment. The advent of new therapies provides encouraging opportunities to improve gout management. However, clinicians should be aware of some of the safety concerns of medications used to treat acute and chronic gout. When prescribing medications for gout one has to be mindful of the presence of comorbidities commonly affecting gout patients that may affect drug safety and efficacy, especially in the elderly and in patients treated with multiple drugs. The benefits of gout drugs, usually, outweigh their safety concerns. Studies are needed in gout patients with chronic kidney disease and/or cardiovascular disease, so that escalation of dosing /combination of anti-inflammatory drugs needed to suppress gouty inflammation as well as escalation of dosing/combination of urate lowering drugs needed to achieve target serum urate level will lead to better understanding of gout treatment safety issues.
