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 …

How Does A Mom's Nutrition Affect Her Children's Health?, Robert A. Waterland, Marcia Wood

Agricultural Research Magazine

In some rural villages of the tiny West African nation of The Gambia, food is generally less available during August and September—the peak of the rainy season—than during a typically dry March through May. Now, a study led by molecular geneticist Robert A. Waterland of the USDA-ARS Children’s Nutrition Research Center in Houston, Texas, has shown that functioning of certain genes in kids conceived during the rainy season differs from that in children conceived during the dry season.

The difference may be explained by a relatively new science referred to as “epigenetics.” The variation appears to be permanent, and in …

Americans everywhere are struggling to lose weight—and to keep from putting those lost pounds right back on. For many, it’s discouraging to have their best efforts fail while those of other dieters succeed.

Researchers at the Agricultural Research Service’s Western Human Nutrition Research Center in Davis, California, are conducting studies that may provide new insights into the underlying causes of this disparity in dieting success.

Given America’s obesity epidemic, such research is timely and relevant. The U.S. Centers for Disease Control and Prevention estimates that 35 percent of U.S. adults and 18 percent of kids and adolescents age 6 through …

Enhancing Yogurt With Healthful Fiber From Oats, Mukti Singh, Sanghoon Kim, Marcia Wood

Agricultural Research Magazine

Adding about one-quarter teaspoon of a fiber-rich component of oats boosts the nutritional value of low-fat yogurt without noticeably affecting the taste or texture of this increasingly popular dairy food.

Oat fiber is of interest to foodmakers and nutritionists alike. Studies with volunteers have shown that it can lower serum cholesterol, which may help improve heart health.

Agricultural Research Service food technologist Mukti Singh, chemist Sanghoon Kim, and their colleagues experimented with adding fiber-containing oat beta-glucan to what’s known in the dairy industry as “low-fat yogurt mix.” It is made up of low-fat milk and a selection of common, safe-to-eat …

Review And Cost Analysis Of Reverse Osmosis And Ultrafiltration, Jared De Groot

Dairy Science

The aim in this study was to determine whether implementing an on farm ultrafiltration system was profitable. Ultrafiltration was researched to reduce the amount of milk hauled from producer to processor. An ultrafiltration system involved milk that flowed through a semi-permeable membrane. Through this process water and small amounts of calcium and ash were pressured through the semi-permeable membrane. This permeate would then be able to feed heifers. The protein, fat, solids nonfat, and small amounts of calcium and ash were retained by the membrane. Through the process of ultrafiltration, raw milk was concentrated to three times its original concentration. …

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. …

Effect Of Post Manufacture Thermal Dip Treatment On Proteolysis Of Commercial String Cheese During Storage, Melissa Karen Hsu

Master's Theses

String cheese, a Mozzarella cheese, has the unique ability to string in fibrous strands when pulled apart. Graders judge string cheese by its stringy texture; samples with copious amounts of string are awarded high ratings. But just as the texture of natural cheeses softens with time, the stringy texture of string cheese can diminish with age too.

Age related softening in cheese is due primarily to an important biochemical event known as proteolysis, which is attributed to inherent milk proteinases, residual coagulant activity, and enzymes from the lysis of starter culture microorganisms. It is hypothesized that a post manufacture heat …

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 …
