Mechanistic Studies Of Intracellular Delivery Of Proteins By Cell-Penetrating Peptides In Cyanobacteria, Betty Revon Liu, Yue-Wern Huang, Han-Jung Lee

Biological Sciences Faculty Research & Creative Works

Background: The plasma membrane plays an essential role in selective permeability, compartmentalization, osmotic balance, and cellular uptake. The characteristics and functions of cyanobacterial membranes have been extensively investigated in recent years. Cell-penetrating peptides (CPPs) are special nanocarriers that can overcome the plasma membrane barrier and enter cells directly, either alone or with associated cargoes. However, the cellular entry mechanisms of CPPs in cyanobacteria have not been studied.

Results: In the present study, we determine CPP-mediated transduction efficiency and internalization mechanisms in cyanobacteria using a combination of biological and biophysical methods. We demonstrate that both Synechocystis sp. PCC 6803 and Synechococcus …

Linking Animal Behavior To Useful Natural Repellents, Sandra Avant

Agricultural Research Magazine

A little monkey business is revealing a few clues about natural remedies that animals use to protect themselves against biting insects and arthropods.

Certain species of animals, such as monkeys and birds, anoint themselves with citrus, other plants, and creatures like millipedes. To find out more about this behavior and to determine if any chemicals in the anointing substances effectively deter ticks and mosquitoes, scientists are examining responses to natural compounds.

Scientists at the Agricultural Research Service Henry A. Wallace Beltsville [Maryland] Agricultural Research Center (BARC) and the Smithsonian Conservation Biology Institute (SCBI) at the National Zoological Park in Front …

Trickery And Other Methods Explored To Vanquish Potato Cyst Nematodes, Roy Navarre, Jan Suszkiw

Agricultural Research Magazine

The pale cyst nematode, Globodera pallida, is one bad roundworm.

Unchecked, it invades the roots of potato and other host crops to feed, obstructing the free flow of nutrients and causing stunted growth, wilted leaves, and other symptoms that can eventually kill the plant. Severe infestations in potato fields can cause yield losses of up to 80 percent.

To make matters worse, female G. pallida nematodes form hard, round cysts that safeguard their eggs from predators and parasites, inhospitable conditions, or a scarcity of food. As many as 30 years may pass before the eggs hatch (cued by a …

A Desert Shrub’S Crystallized Protein Sheds Light On Photosynthesis, Michael Salvucci, Dennis O’Brien

Agricultural Research Magazine

Plants use an enzyme known as “rubisco” to capture carbon dioxide from the atmosphere and, with energy from the sun and nutrients from the soil, build up the shoots, leaves, and stems that make up the plant itself. Scientists have known that for years. They also have known that temperatures are important. When it gets too hot, a rubisco helper protein called “rubisco activase” shuts down, photosynthesis stops, and the plant stops growing. Heat literally unravels the activase protein, and when it does, the result is a less bountiful harvest. Different plants shut down photosynthesis at different temperatures, and the …

A Multispecies Avian Abundance Analysis In Riparian And Oak Woodland Habitats On The California Central Coast, Jacy Hyde

Biological Sciences

I investigated the abundance and diversity of riparian and oak woodland birds in a section of the Los Padres National Forest in Coastal Central California. Point counts were conducted in Oak Woodland and Riparian habitats during the summer of 2012. Point counts were replicated in time (2x) and space (25 replicates). The data were analyzed using Program Distance to correct for differing detection probabilities between species and habitat types. The two habitat types showed no significant difference in species richness. For most species, there was no difference in density between riparian and oak woodland habitats. However, the two species with …

A Comparison Of Relative Ear Length Between Two Neighboring Populations Of Peromyscus Maniculatus, Joshua S. Willems

This study attempts to determine if a significant difference in relative ear length exists between two neighboring populations of Peromyscus maniculatus on the central coast of California. Data was collected from individuals trapped at two plots in the Guadalupe-Nipomo Dunes National Wildlife Refuge and two plots near Black Lake, under the supervision of Francis X. Villablanca, Ph. D. of California Polytechnic State University, San Luis Obispo. A total of 98 individuals were captured over the course of three nights of trapping. A regression analysis was performed comparing the ear lengths of each population relative to body size. The analysis of …

Gas Emissions And Olfactometry For Dairy Heifers, Rebecca Gary

Dairy Science

The objective of this study was to determine any trends in odor evaluations and gas emissions of manure samples in heifers fed high/low concentrate and high/low forage diets. Heifers (n = 8) were enrolled randomly in a split plot design with diet type (high concentrate vs. low concentrate) as the whole plot and forage quality (4 different levels of corn stover within each diet type) as sub-plots in a 4-period (21d) 4X4 Latin square design. Total collection of urine and feces was performed on days 18-21 of each period. The feces to urine ratio (F:U) was determined on days 18 …

Detecting Errors In Generating A Certificate Of Analysis, Breanne Harlan

Dairy Science

Many companies rely on a Certificate of Analysis (COA) to accompany the delivery of their product or material. The COA, required by law, prevents customers from questioning whether a product is safe and ensures manufacturers confirm every product tested passes the Food and Drug Administration’s required specifications. Previous to this project, Kraft Foods Springfield copied their test results for each product from their data warehouse software, called Systems, Applications, and Products onto a Word document to create a COA. This was a systematic approach to detect the possible occurrences of error and reduce the time spent on generating a COA. …

Is Obesity Socially Contagious?, Ciani Jean Sparks

Statistics

The main objective of this paper is to analyze three different articles that discuss whether obesity could be socially contagious. According to the World Health Organization in 2013, obesity is the fifth leading risk for deaths around the world. This disease has dramatically increased in the last decade, which has led scientists to believe there are other factors contributing to the epidemic besides genetics. The first article I analyzed, written by Nicholas Christakis and James Fowler, provided a logistic regression model to estimate the odds of a person becoming obese. The model included the explanatory variables: age, sex, education, smoking …

A Software Tool For The Design Of Critical Robot Missions With Performance Guarantees, Damian M. Lyons, Ronald C. Arkin, Paramesh Nirmal, Shu Jiang, Tsung-Ming Liu

Faculty Publications

Deploying a robot as part of a counter-weapons of mass destruction mission demands that the robotic software operates with high assurance. A unique feature of robotic software development is the need to perform predictably in a physical environment that may only be poorly characterized in advance. In this paper, we present an approach to building high assurance software for robot missions carried out in uncertain environments. The software development framework and the verification algorithm, VIPARS, are described in detail. Results are presented for missions including motion and sensing uncertainty, interaction with obstacles, and the use of sensors to guide behavior.

Modeling Vulnerability Of Groundwater To Pollution Under Future Scenarios Of Climate Change And Biofuels-Related Land Use Change: A Case Study In North Dakota, Usa, Ruopu Li, James W. Merchant

School of Natural Resources: Faculty Publications

Modeling groundwater vulnerability to pollution is critical for implementing programs to protect groundwater quality.Most groundwater vulnerability modeling has been based on current hydrogeology and land use condi- tions. However, groundwater vulnerability is strongly dependent on factors such as depth-to-water, recharge and land use conditions thatmay change in response to future changes in climate and/or socio-economic condi- tions. In this research, a modeling framework, which employs three sets of models linked within a geographic information system (GIS) environment, was used to evaluate groundwater pollution risks under future climate and land use changes in North Dakota. The results showed that areas with …

Differential Root Proteome Expression In Tomato Genotypes With Contrasting Drought Tolerance Exposed To Dehydration, Suping Zhou, Marsha Palmer, Jing Zhou, Sarabjit Bhatti, Kevin J. Howe, Tara Fish, Theodore W. Thannhauser

Agricultural and Environmental Sciences Faculty Research

A comparative proteomics study using isobaric tags for relative and absolute quantitation (iTRAQ) was performed on a mesophytic tomato (Solanum lycopersicum) cultivar and a dehydration-resistant wild species (Solanum chilense) to identify proteins that play key roles in tolerance to water deficit stress. In tomato ‘Walter’ LA3465, 130 proteins were identified, of which 104 (80%) were repressed and 26 (20%) were induced. In S. chilense LA1958, a total of 170 proteins were identified with 106 (62%) repressed and 64 (38%) induced. According to their putative molecular functions, the differentially expressed proteins belong to the following subgroups: stress …

Why ℓ1 Is A Good Approximation To ℓ0: A Geometric Explanation, Carlos Ramirez, Vladik Kreinovich, Miguel Argaez

Departmental Technical Reports (CS)

In practice, we usually have partial information; as a result, we have several different possibilities consistent with the given measurements and the given knowledge. For example, in geosciences, several possible density distributions are consistent with the measurement results. It is reasonable to select the simplest among such distributions. A general solution can be described, e.g., as a linear combination of basic functions. A natural way to define the simplest solution is to select a one for which the number of the non-zero coefficients c_i is the smallest. The corresponding "l₀-optimization" problem is non-convex and therefore, difficult to …
