Global population growth and increased meat demand present challenges for the agricultural industry to produce meat sustainably. In-vitro meat (IVM) is an alternative that could reduce negative impacts associated with livestock production. The goal of this study was to examine consumers’ preferences for IVM. A choice experiment was created with twelve choice tasks that varied across five attributes: production method (IVM or conventional), carbon trust label, organic label, animal welfare label, and price. 1,120 US consumers were randomly assigned to one of four information treatments, differing by information presented regarding IVM: 1) neutral (baseline), 2) positive, 3) negative, and ...
Students Interest And Thoughts On Stem, 2022 Toms River High School North
Students Interest And Thoughts On Stem, Chrisitine Girtain
I am Juan Sebastian Bohorquez Mora, I am a sophomore student at Toms River High School North. I am interested in biofuels because I believe they are a good option to replace fossil fuels. I am also interested in duckweed because biofuels are made out of crops, and people need to eat those crops. That’s when duckweed comes in and it can be used as a feedstock for ethanol production which is a biofuel. Bioethanol is a type of biofuel and it is derived from the corn’s starch. Instead of making ethanol from the corn’s starch, we ...
Diversity Of Bacteriophage In Burkholderia Species, 2022 Bowling Green State University
Diversity Of Bacteriophage In Burkholderia Species, Abigail Price
Bacteriophages are viruses that infect and replicate within bacteria and offer the potential of a therapeutic alternative to chronic infections that do not respond to antibiotic-based therapies. B. vietnamiensis is one of a number of Burkholderia species involved with chronic drug resistant infections in the lungs of individuals with compromised respiratory systems, as found in those with chronic obstructive pulmonary disease and, most especially, are of particular significance in patients with cystic fibrosis. The diversity of the Burkholderia species is explored by using online databases and looking at bacteriophage or phage-encoding viruses found in B. vietnamiensis. The open reading frames ...

Generating Improved RNA Localization Reporters Using the U1hp-U1A System
Ryan Dannemiller, Rebecca Adams, PhD. Belmont University, Nashville, TN.
Messenger mRNA (mRNA) is genetic material that is used to bridge between DNA in the nucleus and protein-making machinery in the cytoplasm of eukaryotic cells. The processes of transcription and translation are physically separated, so the localization of mRNA dictates whether the encoded protein can be generated. In order to observe the localization of specific transcripts in response to stimuli, tools are needed to track location of mRNA. For example, in response to heat shock and ethanol stress, most mRNA is retained ...

Developing An Electroporation Method For Transforming Streptomyces Nymphaeiformis, 2022 Bridgewater College
Developing An Electroporation Method For Transforming Streptomyces Nymphaeiformis, Heather Knott, Stephen Baron
Streptomyces species are notoriously difficult to transform. Streptomyces nymphaeiformis is no different, so a method of electroporation was used to attempt to transform the cells. Multiple growth stages were used in order to alter the degree of development of the cell wall. The procedure did not kill the cells, but the cells were not transformed. Due to the lack of transformation with S. nymphaeiformis, transformation was attempted on two other Streptomyces strains, S. lividans and S. coelicolor. Neither was successfully transformed to thiostrepton (tsr) resistance, nor did they grow on a plate lacking thiostrepton. One possibility for the lack of ...

The Design, Construction, And Testing Of A Recombinant Dna Vaccine For Brucella Abortus And Brucella Melitensis, 2022 Louisiana State University and Agricultural and Mechanical College
The Design, Construction, And Testing Of A Recombinant Dna Vaccine For Brucella Abortus And Brucella Melitensis, Stephanie Lynn Korle
LSU Doctoral Dissertations
Brucella spp. are a bacterium that cause brucellosis, a zoonotic disease, which is commonly seen in cattle, sheep, goats, swine, and canines. Brucellosis is a problem worldwide, although it is eradicated in some countries (Garin-Bastuji et al. 1998). The reason for designing recombinant DNA (rDNA) vaccines opposed to utilizing the live-attenuated vaccines on the market is that they cannot be given to pregnant animals without potentially causing abortion, while an rDNA vaccine should be safe for pregnant animals since it does not contain viable bacteria. Also, there are no serological tests that can accurately distinguish between an animal vaccinated with ...
Characterizing Mechanical Regulation Of Bone Metastatic Breast Cancer Cells, 2022 University of Massachusetts Amherst
Characterizing Mechanical Regulation Of Bone Metastatic Breast Cancer Cells, Boyuan Liu
Breast cancer most frequently metastasizes to the skeleton. Bone metastatic cancer is incurable and induces wide-spread bone osteolysis, resulting in significant patient morbidity and mortality. Mechanical stimuli in the skeleton are an important microenvironmental parameter that modulates tumor formation, osteolysis, and tumor cell-bone cell signaling, but which mechanical signals are the most beneficial and the corresponding molecular mechanisms are unknown. This work focused on bone matrix deformation and interstitial fluid flow based on their well-known roles in bone remodeling and in primary breast cancer. The goal of our research was to establish a platform that could define the relationship between ...

Library/Life Sciences Undergraduate Poster Competition 2022
Djulis (Chenopodium formosanum Koidz.) is a semi-domesticated Taiwanese native crop. It is a BCD-genome hexaploid (2n = 6x = 54) relative of the Andean-native allotetraploid (AABB) quinoa (C. quinoa). Djulis has been grown in a relatively small area by aboriginal Taiwanese, who use it primarily as a fermentation starter to produce ritual alcoholic beverages. Djulis’ seed protein, like that of quinoa, is complete in terms of its human dietary essential amino acid profile; the seed also offers a wide variety of nutritionally important vitamins and minerals. These nutritional attributes have attracted international attention as a novel, healthy grain option. We used PacBio ...

3d Bioprinted Structures From Cells Of Non-Epithelial Mesodermal And Endodermal Lineage Using A Custom Accessible 3d Bioprinting Platform, Xavier-Lewis Palmer, Annette Berkin, Patrick C. Sachs, Robert D. Bruno
College of Engineering & Technology (Batten) Posters
Prior work within our lab has demonstrated the ability to print both murine and human mammary organoids and tumoroids in vitro that can also be reliably transplanted into a murine host for translational studies. Peripherally, this bioprinting system has also been used for 3D printing neurons, stem cells, cancer cells, and a primary cell line rich with fibroblasts, but each of these efforts were with cells of ectodermal lineage. Thus, the system's capacity for use on cells of other origins had been untested. To address this, we have now developed protocols for cells of endodermal and non-epithelial mesodermal/mesenchymal ...
