| Abstract | Brain tissue was analyzed for acetylcholinesterase (AChE) activity from 24 American pronghorn antelope (Antilocapra americana) collected on the US Army Dugway Proving Ground (DPG) (latitude 40°13' 52" N, longitude 112°45' 01" W), Tooele County, Utah. Pronghorn antelope from DPG were evaluated against 26 pronghorn antelope collected in Wyoming. The mean AChE activity was significantly greater (P < 0.001) in the Wyoming control group (4.612 ± 0.193 µM/gm brain tissue/min) relative to DPG (4.032 ± 0.621 µM/gm brain tissue/min). The DPG database exhibited a fourfold greater coefficient of variation, a tenfold greater variance, and a threefold increase in the standard deviation when compared to control AChE activity. Furthermore, the 95% confidence interval for the control and for the DPG data were not overlapping; the entire control data set was greater than the mean DPG AChE activity. A post hoc sequential Bonferroni statistical procedure showed two significantly (P < 0.001) distinct subsets in the DPG data. Mean DPG Subset I AChE activity (4.528 ± 0.347 µM/gm brain tissue/min) was indistinct from the mean control AChE value (4.612 ± 0.193 µM/gm brain tissue/min). The mean DPG Subset II AChE activity (3.537 ± 0.387 µM/gm brain tissue/min) differed significantly (P < 0.001) from the mean control AChE activity. The sum of resulting α values from the multiple statistical tests did not exceed the selected α value of P < 0.05, validating the post hoc sequential Bonferroni statistical procedure. Pronghorn antelope represented by Subset II, experienced a 23.3% mean loss of AChE activity suggesting sub-lethal organophosphate (OP) exposure rather than a low level chronic environmental influence was experienced by a population subset of the DPG pronghorn antelope herd. The origin of the DPG sublethal OP exposure and its long-term effects are speculative. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
