Celiac disease and gluten sensitivities, as well as obesity and overweightrelated disorders, have led to the investigation of gluten-free grains and development of new food products. To address this, refined proso millet and refined corn (control), both gluten-free grains, were used to produce four different product types (muffin, couscous, extruded snack, and porridge). The products contained four different grain combinations (100% proso millet, 75% proso millet/25% corn, 25% proso millet/75% corn, and 100% corn). All products were evaluated for their nutritional composition, in vitro starch digestibility, and expected glycemic index (eGI). Products made with refined proso millet had increased protein (7.6-11.3%), lipid (1.2-6.1%), fiber (7.0-8.8%), and phenolic content (323.5-425 μg/g) compared with those incorporating corn flour (2.5-9.0%, 0.8-4.0%, 2.1-4.1%, and 213-315 μg/g, respectively). As the proso millet content increased, the eGI decreased significantly (P < 0.05). Products made from refined proso millet appear to be good candidates for producing low-GI, gluten-free foods. © 2017 AACC International, Inc.

Pilot-scale data were generated to improve operational guidance for fine bubble diffusion (FBD) and sidestream addition (SSA) systems with respect to unaccounted-for ozone exposure-i.e., concentration times time (C x T)> and bromate formation during ozone dissolution. In FBD systems, results showed significant ozone dissolution C x T (0.31-2.85 mg-min/L) and bromate formation (0.8-9.1 pg/L) occurring in the bubble column, which is not included in regulatory compliance C x T calculations. Utilities may consider taking contactors out of service to minimize contact time and corresponding bromate formation in the dissolution zone. In SSA systems, ozone dosages (7.2-18.6 mg/L) were transferred to approximately 20% of the overall plant flow for -5 s, which produced bromate (2.6-5.7 pg/L). As the contact time exceeded the design guidance in the sidestream flow (>30 s), bromate formation became far more significant (40-140 pg/L). When the sidestream flow is operated with short contact rimes (-5 s), bromate formation can be minimized.

The Cerebral Palsy Computerized Adaptive Test (CP-CAT) is a parent-reported outcomes instrument for measuring lower and upper-extremity function, activity, and global health across impairment levels and a broad age range of children with cerebral palsy (CP). This study was performed to examine whether the Lower Extremity/Mobility (LE) CP-CAT detects change in mobility following orthopaedic surgery in children with CP.This multicenter, longitudinal study involved administration of the LE CP-CAT, the Pediatric Outcomes Data Collection Instrument (PODCI) Transfer/Mobility and Sports/Physical Functioning domains, and the Timed Up & Go test (TUG) before and after elective orthopaedic surgery in a convenience sample of 255 children, four to twenty years of age, who had CP and a Gross Motor Function Classification System (GMFCS) level of I, II, or III. Standardized response means (SRMs) and 95% confidence intervals (CIs) were calculated for all measures at six, twelve, and twenty-four months following surgery.SRM estimates for the LE CP-CAT were significantly greater than the SRM estimates for the PODCI Transfer/Mobility domain at twelve months, the PODCI Sports/Physical Functioning domain at twelve months, and the TUG at twelve and twenty-four months. When the results for the children at GMFCS levels I, II, and III were grouped together, the improvements in function detected by the LE CP-CAT at twelve and twenty-four months were found to be greater than the changes detected by the PODCI Transfer/Mobility and Sports/Physical Functioning scales. The LE CP-CAT outperformed the PODCI scales for GMFCS levels I and III at both of these follow-up intervals; none of the scales performed well for patients with GMFCS level II.The results of this study showed that the LE CP-CAT displayed superior sensitivity to change than the PODCI and TUG scales after musculoskeletal surgery in children with CP.

The phylogenetic placement of Tropidoleptus, a common and distinctive genus of articulated brachiopod, has proved difficult. Tropidoleptus has, for example, been related to orthides, strophomenides and terebratulides. In the first edition of the Treatise, the genus was assigned to the Enteletoidea, largely on the basis of its general shape and the presence of punctation. The cyrtomatodont dentition, however, and complex cardinalia with crurae, apophyses and a median septum are more typical of some of the more unusual rhynchonellides, for example the Uncinuloidea and more specifically the Eatoniidae. A punctate shell condition, nonetheless, has not been reported in that group. It is argued that Tropidoleptus, although it shares many of its features with a number of rhynchonellate orders, has characteristic and unique features justifying the elevation of the Tropidoleptidae to ordinal status, and cladistic analysis places the new order in a basal position within the Rhynchonellata stemgroup. © The Palaeontological Association.

The vapor pressure of hexagonal (Ih) water ice was measured over the temperature range 175 K to 253.4 K and referenced to the value at the triple point of water. This experiment combined a highly accurate humidity generation system containing an ice-coated saturator (millikelvin-level temperature control) to provide humidified streams of nitrogen to a cavity-enhanced laser absorption spectrometer. The measured ice vapor pressures had relative standard uncertainties ranging from 0.4% to 0.7% over the entire temperature range. We demonstrate that these measurements validate thermodynamic correlations for ice vapor pressure based on integration of the Clapeyron equation. Moreover, they also indicate that some commonly used vapor pressure correlations are inaccurate and should be avoided. Key Points Widely used ice vapor pressure correlations are empirical and inexact Accurate thermodynamics-based expressions have been validated down to -100 degrees C These expressions can be reliably extrapolated to temperatures as low as 50 K ©2013.

Polymyxin B is a cationic peptide that inhibits phospholipid-dependent coagulation tests including activated partial thromboplastin time and to a lesser degree prothrombin time. Thrombin clotting time is insensitive to polymyxin B. 2-glycoprotein 1 (2GP1) is a cofactor of antiphospholipid antibodies. Antiphospholipid autoantibodies also poses lupus anticoagulant activity through interactions with 2GP1. Using affinity chromatography, polymyxin B can effectively decrease the binding of 2GP1 to immobilize phosphatidylserine. Since then, anticoagulant effect of polymyxin B is most likely due to the binding to negatively charged phospholipids, preventing formation of coagulation complexes.

Takereana n. gen. is erected for the New Zealand species, Idotea festiva Chilton, 1885, which is redescribed. Takereana, Austridotea Poore, 2001 and Idotea Fabricius, 1798 are the only idoteid genera in which both pleonites 1 and 2 are truly articulating. In all other genera of Idoteidae pleonite 2 is variously fused to pleonite 1 and visible only laterally. The new genus differs from Austridotea in that maxillipedal palp articles 2-3 and 4-5 are fused and operculate whereas in Austridotea the palp is of five free articles or has only articles 4-5 fused. All species of Austridotea are smooth with laterally expanded coxae, a quite different habitus from ornamented Takereana festiva. Takereana differs from Idotea in having two uropodal rami rather than one, greater fusion of maxillipedal palp articles, lacking spiniform setae on the pereopods, and unusual narrow pleopods 1. Takereana has an obsolete setose mandibular molar while it is columnar and toothed in both these genera.

Polyostotic fibrous dysplasia is a skeletal disease that results from somatic activating mutations in the gene GNAS in skeletal stem cells, leading to proliferation of immature osteogenic cells with replacement of normal marrow and bone with fibro-osseous tissue. Lesions may cause bone deformity or fracture. In the surgical care of polyostotic fibrous dysplasia, the role of grafting and the optimal grafting material are not clear. The purpose of this study was to evaluate the long-term survival of bone-grafting procedures in subjects with polyostotic fibrous dysplasia over time.The operative reports and radiographs of a cohort of subjects with polyostotic fibrous dysplasia followed in a natural history study were reviewed. Twenty-three subjects (mean age at the time of enrollment, thirteen years [range, two to forty years]) with fifty-two bone-grafting procedures had a mean follow-up time of 19.6 years (range, twenty-nine months to forty-seven years). Kaplan-Meier life table estimates, Cox proportional hazard models, and t tests comparing means were performed to assess various aspects of graft survival.Kaplan-Meier curves showed a 50% estimate of survival of 14.5 years. Cox proportional hazards models showed no advantage comparing allograft with autograft or structural with nonstructural graft materials. The mean age of the patients was significantly greater (p < 0.001) in the subgroup of subjects in whom grafts were maintained over time (20.9 years) compared with the subgroup of patients whose grafts were resorbed over time (9.8 years).Bone-grafting, including both allograft and autograft, is of limited value in ablating the lesions of fibrous dysplasia. The expectations of patients and surgeons should include the high probability of graft resorption over time with return of bone characteristics of fibrous dysplasia, particularly in younger patients. This suggests the maintenance of normal bone mechanics with implant support should be the priority of any surgical intervention.
