Mountain View College is a community college that is part of the Dallas County Community College District that is located in the Western Park, Oak Cliff area of Dallas, Texas . The school opened its doors in 1970 and features an enrollment of about 10,000 credit students and another 9,000 continuing education students. Mountain View College Wikipedia.

Schizochytrium strain (thraustochytrids) was collected from submerged senescent mangrove leaves from intertidal zone of Dimataling, Zamboanga del Sur. The organism was cultivated in yeast extract peptone and screening of their potentiality to degrade hydrocarbons was done by utilizing used crude oil obtained from Shell station, serving as a carbon source for the growth and energy. The possibility of used crude oil to be degraded by Schizochytrium sp. was done by enrichment culture technique, (a) Oppenheimer -Zobell Gaertner (OZG) (b) basal organic (c) Basal Salt Medium and (d) Yeast Extract Peptone Media (serve as control).Qualitative analysis of the degraded oil was made by ocular inspection of the cell growth and by using High Performance Liquid Chromatography for hydrocarbon detection. Visibility and growth of healthy cells were detected under the light microscope. Biomass production g/L of thraustochytrids cultured in the presence of crude oil revealed varying results for wet weight, the highest biomass was produced by media A with a value of 3.2± and the lowest was produced by media C with a value of 2.4±. Dry weight measurements gave the same pattern as with that of wet weight. The highest value is 2.56 ± for media A and the lowest is 1.3± for media C. Biomass production values in the treatment set-up did not differ significantly from those of the control (wet weight: F = 0.64, df = 3, p > 0.0.60; dry weight: F = 1.41, df = 3, p > 0.30). Results suggest that Schizochytrium sp. under Thraustochytrids is a potential oil-degrading microorganism since the microbe cells exhibits adherence to hydrocarbons. Therefore, the said microorganism is a promising tool for biochemical remediation in cases of oil spill pollution. © 2011 IEEE.

Wireless sensor nodes with impedance measurement capabilities, often based on the Analog Devices AD5933 impedance chip and Atmel's 8-bit ATMega 1281 microcontroller, have been demonstrated to be effective in collecting data for localized damage detection (such as for loose bolt detection) and for sensor self-diagnostics. Previouslydeveloped nodes rely on radio telemetry and off-board processing (usually via a PC) to ascertain damage presence or sensor condition. Recent firmware improvements for the wireless impedance device (WID) now allow seamless integration of the WID with SHMTools and mFUSE, an open-source function sequencer and SHM process platform for Matlab. Furthermore, SHM processes developed using mFUSE can be implemented in hardware on the WID, allowing greater autonomy among the sensor nodes to identify and report damage in real time. This paper presents the capabilities of the newly integrated hardware and software, as well as experimental validation. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

Fish community structure in headwater streams is often influenced by a suite of abiotic variables, such as water depth and flood frequency, channel substrate composition, and in-stream large wood (LW). Wood retained in streams and rivers performs a variety functions; for example, it alters flow, stores sediments, and provides habitat for aquatic biota. The objectives of this study were to (1) quantify and characterize LW, (2) quantify the geomorphic functions of LW, and (3) identify the relationship between LW and fish community structure in Ozark headwater streams. Ten stream reaches with a gradient of LW were sampled in the Ozark-St. Francis National Forest, AR, USA. Single LW pieces, organic accumulations, and root wads were quantified and the geomorphic function of all LW recorded. Fish were identified, enumerated, and massed. LW density in our 10-study streams ranged from <1 to 12 per 100 m2 and >50% functioned to store sediments, stabilize banks, or retain organic matter. Larger diameter wood was associated with altered flow (r=0.64, p=0.04) and LW storing sediments tended to also stabilize banks (r=0.73, p=0.02). There was no relationship between LW metrics and total fish abundance or biomass; however, stream reaches with higher volumes of organic accumulations supported higher creek chub (r2=0.75, p=0.005) and southern redbelly dace biomass (r2=0.62, p<0.02). Although LW densities were among the lowest recorded for US streams, LW still played an integral role in structuring stream geomorphology and providing habitat to some dominant headwater fish species. © 2012 Taylor & Francis.

Purpose: Curcumin is an ideal chemopreventive and antitumor agent characterized by poor bioavailability and low stability. The development of synthetic structural analogues like dimethoxycurcumin (DMC) could overcome these drawbacks. In this study we compared the cytotoxicity, metabolism and the epigenetic changes induced by both drugs in leukemia cells. Methods: Apoptosis and cell cycle analysis were analyzed by flow cytometry. Real-time PCR was used for gene expression analysis. DNA methylation was analyzed by DNA pyrosequencing. The metabolic stability was determined using human pooled liver microsomes. Chromatin Immunoprecipitation was used to quantify histone methylation. Results: Clinically relevant concentration of curcumin and DMC were not cytotoxic to leukemia cells and induced G2/M cell cycle arrest. DMC was more metabolically stable than curcumin. Curcumin and DMC were devoid of DNA hypomethylating activity. DMC induced the expression of promoter methylated genes without reversing DNA methylation and increased H3K36me3 mark near the promoter region of hypermethylated genes. Conclusion: DMC is a more stable analogue of curcumin that can induce epigenetic changes not induced by curcumin. DMC induced the expression of promoter methylated genes. The combination of DMC with DNA methyltransferase inhibitors could harness their combined induced epigenetic changes for optimal re-expression of epigenetically silenced genes. © 2014 Springer Science+Business Media New York.
