Genomic and physiological responses in Gulf killifish (Fundulus grandis) in the northern Gulf of Mexico have confirmed oil exposure of resident marsh fish following the Macondo blowout in 2010. Using these same fish, we evaluated otolith microchemistry as a method for assessing oil exposure history. Laser-ablation inductively-coupled-plasma mass spectrometry was used to analyze the chemical com...
Increased shipping in British Columbia (BC) waters poses risks for marine birds from marine oil spills. Ancient Murrelets (Synthliboramphus antiquus), small marine diving birds of which half of the world's population breeds in BC, are especially susceptible to oiling immediately after departing from their breeding colonies, as their offspring are flightless, constraining their parents to remain...
Northern Gulf of Mexico (NGoM) loggerheads (Caretta caretta) make up one of the smallest subpopulations of this threatened species and have declining nest numbers. We used satellite telemetry and a switching state-space model to identify distinct foraging areas used by 59 NGoM loggerheads tagged during 2010-2013. We tagged turtles after nesting at three sites, 1 in Alabama (Gulf Shores; n = 37)...
This paper presents a case study in the development and application of a time study model in a hollowware aluminium manufacturing plant. The organization engages in the production of three product lines: kettles, frying pans, and cooking pots of diverse categories. The motivation for this study was the need to intervene in frequent crises that normally arose between the employee-association and...
Microphytobenthic communities play a significant role in nutrient modulation, sediment stabilization, and primary production seagrass beds, which provide various ecosystem services. We hypothesized that microphytobenthic sediments of chronically oil-exposed beds will exhibit increased resiliency to stressors associated with oil exposure as opposed never exposed spills. prepared 14-liter seawate...
The British Petroleum Deepwater Horizon Oil Spill in the Gulf of Mexico was the biggest oil spill in US history. To assess the impact of the oil spill on the saltmarsh plant community, we examined Advanced Visible Infrared Imaging Spectrometer (AVIRIS) data flown over Barataria Bay, Louisiana in September 2010 and August 2011. Oil contamination was mapped using oil absorption features in pixel ...
The emulsification of oil at the Deepwater Horizon (DWH) well head relegated a large proportion of resultant hydrocarbon plumes to the deep sea, facilitated the incorporation of oil droplets into microbial and planktonic food web, and limited the severity of direct, wetland oiling to coastal Louisiana. Nevertheless, many transient fish and invertebrate species rely on offshore surface waters fo...
A multi-year unusual mortality event (UME) involving primarily common bottlenose dolphins (Tursiops truncates) was declared in the northern Gulf of Mexico (GoM) with an initial start date of February 2010 and remains ongoing as of August 2014. To examine potential changing characteristics of the UME over time, we compared the number and demographics of dolphin strandings from January 2010 throu...
Abstract: Background: Non-alcoholic fatty liver is a disease that will lead to liver cirrhosis if not treated. Curcumin is the active substance of the rhizome of the turmeric plant, which has antioxidant, anti-inflammatory, antimicrobial, etc. properties. In the present study, the effects of curcumin analogue on the expression of SIRT1 and FAS genes and the accumulation of triglycerides in f...
آلفا 1- آنتی تریپسین (aat) گلیکوپروتئینی با 394 آمینواسید و حدود 54 کیلودالتون وزن مولکولی می باشد. این پروتئین فاز حاد با مهار آنزیم الاستاز نوتروفیلی، ریه را در مقابل اثرات تخریبی این آنزیم در مواقع التهاب محافظت می کند. تولید این پروتئین به طریقه نوترکیب سالهاست که مورد توجه شرکت های دارویی است. در میان انواع سیستم های تولید کننده، مخمر پیکیا پاستوریس به لحاظ انجام فرایند گلیکولیزاسیون، کم ه...
