Circadian Activity of Topical 0.05% Betamethasone Dipropionate in Human Skin In Vivo
The influence of treatment duration, vehicle, and time of day of application on topical 0.05% betamethasone dipropionate uptake into human stratum corneum and the resulting skin- blanching response was investigated in human subjects. Drug uptake into stratum corneum and the resulting skin color changes measured with a chromameter demonstrate an equilibrium delay. Maximal drug uptake occurred at 2 h, whereas maximal skin color changes occurred 6h after a single application. Extent of decreased skin color was dependent on vehicle, treatment duration, and time of day of application. Time of maximal decreased skin color occurred at midnight independent of vehicle, treatment duration, or time of day of application. This time of maximal drug activity coincides with the well-known time period of lowest circulating cortisol concentrations (2000-0400 h). Application of a single 2- or 6-h dose of the 0.05% cream at 1600h produced more extensive and prolonged changes in skin color over 24h than a 0900-h application in the same subject. These data demonstrate that the extent and duration of topical corticosteroid activity in human skin is influenced by vehicle, treatment duration, and time of day of application. The prolonged changes in skin color measured with a single dose applied at 1600h suggest that a once-a-day dosing regimen in the late afternoon may be sufficient for dermatologic therapy. Elucidation of these circadian responses with topical corticosteroids may provide a rational basis for the future re-evaluation of the appropriate therapeutic regimen with this class of drugs in dermatologic medicine

From Process to Product: Your Risk Process at Work
The Space Life Sciences Directorate (SLSD) and Human Research Program (HRP) at the NASA/Johnson Space Center work together to address and manage the human health and performance risks associated with human space flight. This includes all human system requirements before, during, and after space flight, providing for research, and managing the risk of adverse long-term health outcomes for the crew. We previously described the framework and processes developed for identifying and managing these human system risks. The focus of this panel is to demonstrate how the implementation of the framework and associated processes has provided guidance in the management and communication of human system risks. The risks of early onset osteoporosis, CO2 exposure, and intracranial hypertension in particular have all benefitted from the processes developed for human system risk management. Moreover, we are continuing to develop capabilities, particularly in the area of information architecture, which will also be described. We are working to create a system whereby all risks and associated actions can be tracked and related to one another electronically. Such a system will enhance the management and communication capabilities for the human system risks, thereby increasing the benefit to researchers and flight surgeons
Differential Gene Expression Profiling of Orbital Adipose Tissue in Thyroid Orbitopathy
Published under a Creative Commons Attribution-NonCommercial-NoDerivatives License (http://creativecommons.org/licenses/by-nc-nd/4.0/legalcode)PURPOSE. We aimed to determine differentially expressed genes relevant to orbital
inflammation and orbital fat expansion in thyroid orbitopathy (TO) using microarray gene
profiling in a case-control study.
METHODS. Human orbital adipose samples were obtained from individuals with active TO (n ¼
12), inactive TO (n ¼ 21), and normal controls (n ¼ 21). Gene expression profiles were
examined using microarray analysis and were compared between active and inactive TO, and
between active TO and normal controls. Top ranked differentially expressed genes were
validated by real-time RT-PCR in an additional eight active TO, 13 inactive TO, and 11 normal
controls and correlated with gene set enrichment analysis (GSEA) and molecular pathways
analysis.
RESULTS. Seven hundred twenty-one probes (683 genes) and 806 probes (735 genes) were
significantly differentially expressed in comparing active to inactive TO and in comparing
active TO to healthy controls, respectively. All selected genes were confirmed to be
differentially expressed by real-time RT-PCR. Multiple top ranked genes in active versus
inactive TO comparison are overrepresented by immune and inflammatory response genes.
They include defensins (DEFA1, DEFA1B, DEFA3), which were overexpressed by 3.05- to
4.14-fold and TIMD4 by 4.20-fold. Markers for adipogenesis were overexpressed including
SCD, FADS1, and SCDP1. Gene set enrichment analysis revealed dysregulation of epigenetic
signatures, T-cell activation, Th1 differentiation, defensin pathway, cell adhesion, cytoskeleton
organization, apoptosis, cell cycling, and lipid metabolism in active TO.
CONCLUSIONS. Active TO is characterized by upregulation of genes involved in cell-mediated
immune, innate immune, and inflammatory response and enhanced orbital adipogenesis.
TIMD4, DEFA1, DEFA1B, and DEFA3 genes may be involved in the innate immune-mediated
orbital inflammation in TO. Epigenetic mechanisms may play a role in the pathogenesis of TO

Genetically Determined Plasma Lipid Levels and Risk of Diabetic Retinopathy: A Mendelian Randomization Study.
Results from observational studies examining dyslipidemia as a risk factor for diabetic retinopathy (DR) have been inconsistent. We evaluated the causal relationship between plasma lipids and DR using a Mendelian randomization approach. We pooled genome-wide association studies summary statistics from 18 studies for two DR phenotypes: any DR (N = 2,969 case and 4,096 control subjects) and severe DR (N = 1,277 case and 3,980 control subjects). Previously identified lipid-associated single nucleotide polymorphisms served as instrumental variables. Meta-analysis to combine the Mendelian randomization estimates from different cohorts was conducted. There was no statistically significant change in odds ratios of having any DR or severe DR for any of the lipid fractions in the primary analysis that used single nucleotide polymorphisms that did not have a pleiotropic effect on another lipid fraction. Similarly, there was no significant association in the Caucasian and Chinese subgroup analyses. This study did not show evidence of a causal role of the four lipid fractions on DR. However, the study had limited power to detect odds ratios less than 1.23 per SD in genetically induced increase in plasma lipid levels, thus we cannot exclude that causal relationships with more modest effect sizes exist

Treatment of Produced Water Using a Surfactant Modified Zeolite/Vapor Phase Bioreactor System
Co-produced water from the oil and gas industry accounts for a significant waste stream in the United States. Produced waters typically contain a high total dissolved solids content, dissolved organic constituents such as benzene and toluene, an oil and grease component as well as chemicals added during the oil-production process. It has been estimated that a total of 14 billion barrels of produced water were generated in 2002 from onshore operations (Veil, 2004). Although much of this produced water is disposed via reinjection, environmental and cost considerations can make surface discharge of this water a more practical means of disposal. In addition, reinjection is not always a feasible option because of geographic, economic, or regulatory considerations. In these situations, it may be desirable, and often necessary from a regulatory viewpoint, to treat produced water before discharge. It may also be feasible to treat waters that slightly exceed regulatory limits for re-use in arid or drought-prone areas, rather than losing them to reinjection. A previous project conducted under DOE Contract DE-AC26-99BC15221 demonstrated that surfactant modified zeolite (SMZ) represents a potential treatment technology for produced water containing BTEX. Laboratory and field experiments suggest that: (1) sorption of benzene, toluene, ethylbenzene and xylenes (BTEX) to SMZ follows linear isotherms in which sorption increases with increasing solute hydrophobicity; (2) the presence of high salt concentrations substantially increases the capacity of the SMZ for BTEX; (3) competitive sorption among the BTEX compounds is negligible; and, (4) complete recovery of the SMZ sorption capacity for BTEX can be achieved by air sparging the SMZ. This report summarizes research for a follow on project to optimize the regeneration process for multiple sorption/regeneration cycles, and to develop and incorporate a vapor phase bioreactor (VPB) system for treatment of the off-gas generated during air sparging. To this end, we conducted batch and column laboratory SMZ and VPB experiments with synthetic and actual produced waters. Based on the results of the laboratory testing, a pilot scale study was designed and conducted to evaluate the combined SMZ/VPB process. An economic and regulatory feasibility analysis was also completed as part of the current study to assess the viability of the process for various water re-use options
