Collaborative Learning Utilizing A Domain-Based Shared Data Repository To Enhance Learning Outcomes, David J. Lubliner

Dissertations

A number of learning paradigms have postulated that knowledge formation is a dynamic process where learners actively construct a representation of concepts integrating information from multiple sources. Current teaching strategies utilize a compartmentalized approach where individual courses contain a small subset of the knowledge required for a discipline. The intent of this research is to provide a framework to integrate the components of a discipline into a cohesive whole and accelerate the integration of concepts enhancing the learning process. The components utilized to accomplish these goals include two new knowledge integration models; a Knowledge Weighting Model (KWM) and the Aggregate-Integrate-Master …

Preparation Of Nanovehicles For Targeted Drug Delivery, Anagha Avinash Bhakay

Theses

Application of nanotechnology in pharmaceutical research has opened new frontiers for drug development and its efficient delivery. In recent years, the focus of the research has been on the engineering of nano/micro-particulate structures for efficient and targeted delivery of drugs for selective and enhanced absorption. This work throws light on the preparation of biodegradable and non-toxic nanoparticulate systems for targeted drug delivery. The drug vehicles were made by two different processes namely electrostatic interactions and desolvation process. The drug carriers made by these processes were found to be in the size range of 150-200nm which is necessary for cellular uptake …

Assessing Trainer Hand Forces For Manual Body Weight Supported Walking, Manish Raval

Theses

Spinal cord injuries occur in approximately 12,000 to 15,000 people per year in the U.S. About 10,000 of these people are permanently paralyzed. Most spinal cord traumas occur in young, healthy individuals. Males between 15 and 35 years old are most commonly affected.

Recently new approaches to facilitate walking recovery for individuals after a spinal cord injury, have been directed towards a therapy known as Locomotor Training (LT) that implements repetitive stepping on a treadmill using body weight support. A major intent of LT research is to investigate the effect of an extended period of LT on bilateral muscle activation …

Rna Secondary Structure Detection Programs With An Emphasis On Covariance Models, Justin Slotman

Theses

RNA secondary structure prediction requires a different approach from traditional alignment methods. Functional RNAs often have their secondary structure better conserved than their primary structure. Covariance models, probabilistic models that utilize stochastic-context-free grammars, are one approach. CMs allow for homology to be detected where purely sequence-based methods would fail. A background on CMs is given, as well as a background of the major classes of non-coding RNAs (ncRNAs). Comparisons are made between some CM-using tools (the Infernal suite and CMfinder) and some other RNA secondary structure tools (CARNAC, miRNAminer, Pfold, Mfold) as well as between Infernal and the primary alignment …

Deciphering The Biology Of Axon Stretch-Growth, Joseph R. Loverde

Theses

Traditional nerve regeneration strategies focus on growth cone-mediated growth, a form of nerve growth that occurs primarily during embryogenesis. Early axons continue to grow from the end distal to the soma, seeking targets on which to synapse. It is believed that once the axons synapse, stretch-growth takes over and is responsible for the great lengths achieved by nerves of the central and peripheral nervous systems. Recent work has demonstrated stretch-growth in vitro resulting in dramatically increased growth rates compared to the growth cone. Here, the aim was to decipher the underlying biology associated with axon stretch-growth using two approaches. First, …

Phytochemical Screening And Antibacterial Activity Of Aqueous And Methanolic Leaf Extracts Of Two Medicinal Plants Against Bovine Mastitis Bacterial Pathogens, M. P. Ayyappa Das, R. Dhanabalan, A. Doss, M. Palaniswamy

Ethnobotanical Leaflets

Spathodea campanulata P. Beauv is extensively used in Indian traditional and folklore medicines to cure various human ailments. Tridax procumbens Linn is a tropically distributed medicinal plant. Antimicrobial activity of aqueous and methanol extracts of two plants were investigated by agar disc and well-diffusion method against bovine mastitis bacterial pathogens. The plant extracts showed inhibitory activity against the tested organisms. Phytochemical screening of the plant revealed the presence of tannins, flavonoids, saponins and alkaloids. The study scientifically validates the use of plant in traditional and ethnoveterinary medicine.

In Vitro Antioxidant And Cytotoxic Analysis Of Boerhaavia Diffusa Linn., Priya Darsini D. Teepica, J. M. Sasikumar, M. Kulandhaivel

Ethnobotanical Leaflets

The present study was carried out to evaluate the antioxidant and cytotoxic activity of unexploited plant, Boerhaavia diffusa indigenous to India. Different concentrations of the ethanolic whole-plant extracts (1000, 500, 250, 125, 50, 25, 12.5 μg/ml) were subjected to 1,1-diphenyl -2-picryl hydrazyl (DPPH) radical scavenging, reducing power activity and cytotoxic study against vero cell lines. The maximum DPPH radical scavenging potential was found to be 93% at 1000 μg/ml with IC50 (Inhibitory Concentration) value being 49.95±1.15 μg/ml. The maximum reducing power of the extract at 700nm was found to be 0.997±0.081 at 1000 μg/ml. The inhibition percentage with regard to …

Ethnobotanical Leaflets

The present study was carried out to evaluate the hepatoprotective role of leaf extracts of Azadirachta indica A. Juss. Hepatoprotective activities of ethanolic and aqueous extracts of A. indica were examined against carbon tetrachloride induced liver damage in mice using silymarin as control. Enzyme activities of Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT) and Alkaline Phosphatase (ALP) were analyzed. Phytochemical leaf extracts of A. indica exhibited significant hepatoprotective activity. Ethanolic and aqueous leaf extracts of A. indica exhibited moderate activity over carbon tetrachloride treated animals. Results confirm the traditional - ethnomedicinal use of A. indica as a …

Ethnobotanical Leaflets

Socio-economic parameters have significant impact on consumer’s attitude towards the usage of traditional system of medicine in Tamilnadu, India. Though traditional systems of medicine have made significant contributions towards fulfilling healthcare needs of the people in the past, impacts of modern medicine have been so large that traditional medicine witnessed a dark period in India. While such practices are common in the rural/ remote areas, off late, change in the trend with respect to the usage of Siddha medicine as complementary alternative therapy among urban population has been observed. Present study aims to evaluate the resurgence of interest in Siddha …

A Structural Interpretation Of The Effect Of Gc-Content On Efficiency Of Rna Interference, Chi Yu Chan, C Steven Carmack, Dang D. Long, Anil Maliyekkel, Yu Shao, Igor Roninson, Ye Ding

Faculty Publications

BACKGROUND: RNA interference (RNAi) mediated by small interfering RNAs (siRNAs) or short hairpin RNAs (shRNAs) has become a powerful technique for eukaryotic gene knockdown. siRNA GC-content negatively correlates with RNAi efficiency, and it is of interest to have a convincing mechanistic interpretation of this observation. We here examine this issue by considering the secondary structures for both the target messenger RNA (mRNA) and the siRNA guide strand. RESULTS: By analyzing a unique homogeneous data set of 101 shRNAs targeted to 100 endogenous human genes, we find that: 1) target site accessibility is more important than GC-content for efficient RNAi; 2) …

Coherent Anti-Stokes Raman Scattering Imaging Of Lipids In Cancer Metastasis., Thuc T. Le, Terry B. Huff, Ji-Xin Cheng

Weldon School of Biomedical Engineering Faculty Publications

Background

Lipid-rich tumours have been associated with increased cancer metastasis and aggressive clinical behaviours. Nonetheless, pathologists cannot classify lipid-rich tumours as a clinically distinctive form of carcinoma due to a lack of mechanistic understanding on the roles of lipids in cancer development.

Methods

Coherent anti-Stokes Raman scattering (CARS) microscopy is employed to study cancer cell behaviours in excess lipid environments in vivo and in vitro. The impacts of a high fat diet on cancer development are evaluated in a Balb/c mice cancer model. Intravital flow cytometry and histology are employed to enumerate cancer cell escape to the bloodstream and …
