Decoding Bacterial Resilience: Srnas And Sigma Factors In Stress Adaptation And Persistence Of Salmonella, Anita Nguyen May 2025

Decoding Bacterial Resilience: Srnas And Sigma Factors In Stress Adaptation And Persistence Of Salmonella, Anita Nguyen

Poster Presentations

Small RNAs (sRNAs) are noncoding RNA molecules in bacteria that function primarily to regulate gene expression, including those associated with stress. The Borchert Lab has identified 173 sRNAs and > 500 sRNAs that are responsive to desiccation and carbon starvation (c-starvation), respectively. Prokaryotic transcription involves an RNA Polymerase (RNAP) that transcribes DNA into RNA. RNAP involves sigma factors, which recognize promoters for the initial steps of RNA synthesis. The Borchert Lab has determined that there are significant overlaps between sRNAs expressed in cells subjected to both short-term durations and long-term durations of carbon starvation. Salmonella enterica serovars can have outbreaks associated …


Science, Physiology, And Nutrition For The Nonscientist, Judi S. Morrill Jan 2025

Science, Physiology, And Nutrition For The Nonscientist, Judi S. Morrill

Open Educational Resources

A wonderful blend of physiology, nutrition, biochemistry, genetics, biology, evolution, chemistry--what we all need to know as informed citizens. A basic knowledge of the life sciences and how our bodies work--to promote our own good health, especially as we're bombarded with misleading advertisements, soundbites, and the like. DNA fingerprinting, calorie requirements, dietary advice, genetic engineering (including gene editing with CRISPR cas9)--all in an easy-to understand book.

Cahs Researchers Receive Provisional Patent For Potential Plant Sweetener, Aruna Weerasooriya, Godson Osuji, Laura Carson, Peter Ampim, Subhani Bandara, Eric Obeng, Sela Woldesenbet May 2021

Cahs Researchers Receive Provisional Patent For Potential Plant Sweetener, Aruna Weerasooriya, Godson Osuji, Laura Carson, Peter Ampim, Subhani Bandara, Eric Obeng, Sela Woldesenbet

Datasets Collection

The plant is a perennial herb native to southern Mexico, the Caribbean, Central America, Colombia, and Venezuela. It is commonly known as the Aztec sweet herb, bushy lippia, honey herb, or hierba dulce, used as a natural sweetener and medicinal herb in its native Mexico and parts of Central America. The Aztecs used it and introduced it to the Spanish when they arrived. A compound called Hernandulcin, whose sweetness is about 1,000 times higher than in sucrose, provides the plant’s sweet taste.The plant has low Hernandulcin production in its tissues. Despite its sweetness, it isn’t used in the natural sweetener …


Purple Variety Of Sweet Potato, Ming Gao Apr 2021

Purple Variety Of Sweet Potato, Ming Gao

Datasets Collection

Purple sweet potatoes are versatile enough to be used in cupcakes as well as ice cream. However, when cooked in their natural state, they are dry and starchy, prompting most to use the purple sweet potatoes as flour for baked goods, or in some cases, for ice cream. Dr. Gao wants his variety of purple sweet potato to be more palatable. Gao earned the coveted USDA-National Institute of Food and Agriculture 1890 Institution Capacity Building Grant to support his research. The project will focus on developing a variety that is enjoyable in its natural state and is moist and tastefully …


You Are What You Eat At Any Age: Carbon And Nitrogen Analysis Of Mummies From An Ancient Egyptian Necropolis, Stephen Funk, R. Paul Evans Apr 2019

You Are What You Eat At Any Age: Carbon And Nitrogen Analysis Of Mummies From An Ancient Egyptian Necropolis, Stephen Funk, R. Paul Evans

Library/Life Sciences Undergraduate Poster Competition 2019

The BYU Egypt Project at Fag el-Gamus necropolis and adjacent Seila Pyramid has studied over 700 mummies excavated over the past 30 years. The necropolis includes an open area with densely located vertical burial shafts and a hill with horizontal burial shafts. The chronological and dietary history of the mummies was assessed using stable isotopy and 14C analysis of accessible biological samples.


Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell Jan 2002

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell

Bulletins 4000 -

The effect of Quartermate pre-milking teat sanitation on milk quality was investigated in twelve dairy herds over a period of eight weeks. Pre-milking teat sanitation was carried out on all cows for six weeks on each of six farms and mesophile and thermophile bacteria counts of raw milks were compared before the milk line (“cluster” samples), and at various points within milking plants. Rates of mastitis, vat milk iodide levels and specific bacteria were also monitored.
