BACKGROUNDHead and neck squamous cell carcinomas (HNSCCs) are debilitating diseases for which a patient's prognosis depends heavily on complete tumor resection. Currently, the surgeon's fingers determine the location of tissue margins. This study evaluated the diagnostic utility of a novel imaging modality, dynamic optical contrast imaging (DOCI), in the detection of HNSCC. This system generates contrast by illuminating the tissue with pulsed light and detecting variations in endogenous fluorophore lifetimes.METHODSA total of 47 fresh ex vivo samples from 15 patients were imaged with the DOCI system immediately after surgical resection. DOCI maps were analyzed to determine the statistical significance of contrast between tumors and adjacent nonmalignant tissue. Pilot intraoperative clinical data were also acquired.RESULTSStatistical significance (P < .05) between muscle and tumor was established for 10 of 10 emission wavelengths, between collagen and tumor for 8 of 10 emission wavelengths, and between fat and tumor for 2 of 10 wavelengths. The system extracted relative fluorescence decay information in a surgically relevant field of view in <2 minutes.CONCLUSIONSThis study demonstrates the feasibility of using DOCI to rapidly and accurately distinguish HNSCC from surrounding normal tissue. An analysis of DOCI images revealed microscopic characterization sufficient for tissue‐type identification consistent with histology. Such an intraoperative tool would be transformative by allowing the rapid delineation of tumor tissue from nontumor tissue and thus maximizing the efficacy of resection and improving patient outcomes.

Published: October 2016

BACKGROUNDAmerican Indian and Alaska Native (AI/AN) breast cancer survivors experience disparities in breast cancer incidence and age‐adjusted mortality compared with non‐Hispanic white (NHW) breast cancer survivors. In addition, mortality‐to‐incidence rates indicate that AI/ANs continue to have the poorest survival from breast cancer compared with other racial groups. “Native American Cancer Education for Survivors” (NACES) is a cultural education and support intervention for AI/AN patients with cancer that collects data from voluntary participants through the NACES quality‐of‐life (QOL) survey regarding their cancer experience and survivor journey.METHODSData from the NACES QOL survey were analyzed to determine whether barriers accessing and during initial cancer treatment impacted QOL domains for AI/AN cancer survivors. Exploratory analyses of selected variables were conducted and were followed by Kruskal‐Wallis tests to determine whether these barriers influenced survivorship QOL for AI/AN breast cancer survivors.RESULTSAI/AN breast cancer survivors' social QOL was significantly affected by barriers to accessing cancer treatment. Many respondents experienced barriers, including a lack of cancer care at local clinics and the distance traveled to receive cancer care. During treatment, too much paperwork and having to wait too long in the clinic for cancer care were the most frequently reported barriers.CONCLUSIONSTreatment barriers influence AI/AN breast cancer survivors' social QOL. Mediating these barriers is crucial to ameliorating AI/AN survivors' disparities when accessing and completing cancer treatment and improving survivorship QOL.

AbstractBackgroundType 1 diabetes mellitus (T1D) is mediated by autoaggressive T effector cells with an underlying regulatory T‐cell (Treg) defect. Vitamin D deficiency is highly prevalent in T1D, which can aggravate immune dysfunction. High‐dose vitamin D treatment may enhance Tregs and improve metabolism in T1D patients.MethodsIn a randomized double‐blind placebo‐controlled trial with crossover design, patients received either for 3 months cholecalciferol 4000 IU/d followed by 3 months placebo or the sequential alternative. Thirty‐nine T1D patients (19 women and 20 men) completed the trial.ResultsPrimary outcome was a change of Tregs, secondary HbA1C, and insulin demand. Effects were evaluated based on intra‐individual changes between treatment and placebo periods for outcome measures. Exploratory analyses included vitamin D system variant genotyping and C‐peptide measurements. Median 25(OH)D3 increased to 38.8 ng/ml with males showing a significantly stronger increase (p = .003). T‐lymphocyte profiles did not change significantly (p > 2); however, the intra‐individual change of Tregs between males and females was different with a significantly stronger increase in men (p = .017), as well as between genotypes of the vitamin D receptor (Apa, Taq, and Bsm: genotypes aa, TT, and bb; p = .004–0.015). Insulin demands declined significantly (p = .003–.039) and HbA1C improved (p < .001). Random C‐peptide levels were low but rising (median, 0.125 ng/ml; range, 0.02–0.3) in 6 patients. No toxicity was observed.ConclusionA daily vitamin D dose of 4000 IU for 3 months was well tolerated and enhanced Tregs in males. Glucometabolic control improved in all. Subsequent larger trials need to address ß‐cell function and genotyping for individualized vitamin D doses.

Published: October 2016

AbstractYankee whalers of the 19th century had major impacts on populations of large whales, but these leviathans were not the only taxa targeted. Here, we describe the “collateral damage,” the opportunistic or targeted taking of nongreat whale species by the American whaling industry. Using data from 5,064 records from 79 whaling logs occurring between 1840 and 1901, we show that Yankee whalers captured 5,255 animals across three large ocean basins from 32 different taxonomic categories, including a wide range of marine and terrestrial species. The taxa with the greatest number of individuals captured were walruses (Odobenus rosmarus), ducks (family Anatidae), and cod (Gadus sp.). By biomass, the most captured species were walruses, grampus (a poorly defined group within Odontoceti), and seals (family Otariidae). The whalers captured over 2.4 million kg of nongreat whale meat equaling approximately 34 kg of meat per ship per day at sea. The species and areas targeted shifted over time in response to overexploitation of whale populations, with likely intensive local impacts on terrestrial species associated with multiyear whaling camps. Our results show that the ecosystem impacts of whaling reverberated on both marine and coastal environments.
The absorption and evaporation of water vapor by epiphytes in an old‐growth Douglas‐fir forest during the seasonal summer dry season: Implications for the canopy energy budget

Published: October 2016

AbstractOur goal was to determine how epiphytic lichens and bryophytes affect canopy latent heat fluxes in an old‐growth Douglas‐fir forest when the canopy was dry. The epiphyte water content (WCe expressed as a percent of dry weight) of representative epiphytic foliose lichens, fruticose lichens, and bryophytes was measured in the laboratory after 1 to 12 hr of exposure at five different values of vapor pressure deficit (VPD). After 12 hr of exposure, WCe increased fivefold to sixfold as VPD decreased from 1849 to 132 Pa. In addition, we measured WCe in the field using strain gauges. These field measurements were used to calibrate the models described below. Two models were created to estimate the potential latent heat flux from epiphytes at the canopy scale (LEe). The first model combined measured total biomass of epiphytes with a model that estimated the laboratory determined VPD‐dependent changes in WCe of the lichens/bryophytes (VPD method). The second model estimated LEe by scaling the change in WCe of epiphyte‐laden branches that were continuously monitored in situ in the canopy by a strain gauge (SG method). Both methods showed a strong diurnal trend in LEe when VPD was less than 645 Pa. Prior to sunrise, the epiphytes absorbed water, corresponding to a latent heat flux of 5 to 15 W/m2 per unit ground area, whereas after sunrise, the epiphytes lost water at a rate of −10 to −20 W/m2. For short periods, epiphytes may contribute a significant portion of the latent heat flux from Douglas‐fir forests.
Ecosystem engineers drive creek formation in salt marshes
Authors: Vu Huy D. , Wie˛ski Kazimierz , Pennings Steven C. 
Published: October 2016

AbstractEcosystem engineers affect different organisms and processes in multiple ways at different spatial scales. Moreover, similar species may differ in their engineering effects for reasons that are not always clear. We examined the role of four species of burrowing crabs (Sesarma reticulatum, Eurytium limosum, Panopeus herbstii, Uca pugnax) in engineering tidal creek networks in salt marshes experiencing sea level rise. In the field, crab burrows were associated with heads of eroding creeks and the loss of plant (Spartina alterniflora) stems. S. reticulatum was closely associated with creek heads, but densities of the other crab species did not vary across marsh zones. In mesocosm experiments, S. reticulatum excavated the most soil and strongly reduced S. alterniflora biomass. The other three species excavated less and did not affect S. alterniflora. Creek heads with vegetation removed to simulate crab herbivory grew significantly faster than controls. Percolation rates of water into marsh sediments were 10 times faster at creek heads than on the marsh platform. Biomass decomposed two times faster at creek heads than on the marsh platform. Our results indicate that S. reticulatum increases creek growth by excavating sediments and by consuming plants, thereby increasing water flow and erosion at creek heads. Moreover, it is possible that S. reticulatum burrows also increase creek growth by increasing surface and subsurface erosion, and by increasing decomposition of organic matter at creek heads. Our results show that the interaction between crab and plant ecosystem engineers can have both positive and negative effects. At a small scale, in contrast to other marsh crabs, S. reticulatum harms rather than benefits plants, and increases erosion rather than marsh growth. At a large scale, however, S. reticulatum facilitates the drainage efficiency of the marsh through the expansion of tidal creek networks, and promotes marsh health.
Single‐Inductor Dual‐Output DC–DC Converter Design Using RC Ripple Regulator Method

Published: October 2016

SUMMARYIn this paper, we have proposed Single‐Inductor Dual‐Output (SIDO) buck–buck and boost–boost dc–dc converter using improved RC ripple regulator control. The proposed SIDO buck–buck converter has the characteristics of low‐ripple and high control frequency. RC ripple regulator control cannot be applied to SIDO boost–boost converter because RC ripple regulator undergoes self‐excited oscillation and two self‐excited oscillating controllers make the SIDO converter unstable. Thus we proposed the priority circuit for RC ripple regulator control. The proposed control circuit improves response characteristic and simplicity of the control circuit. Simulations are performed to verify the validity of the proposed SIDO converter. Simulation results indicate good performance of the proposed SIDO converter.
