Dose reconstruction in the large Japanese field mouse using electron paramagnetic resonance spectroscopy of tooth enamel

2020 Summer.Includes bibliographical references.Electron spin resonance (ESR) analysis of tooth enamel is recognized as a reliable method for lifetime dose reconstruction, particularly in human tooth enamel. While the use of ESR to reconstruct dose is well understood for human tooth enamel, the reliability and usefulness of dose reconstruction using ESR in mouse tooth enamel has not been as thoroughly studied. This paper aims to resolve this gap in knowledge concerning the use of the tooth enamel from the Large Japanese Field Mouse as acting dosimeter using EPR spectroscopy. Methods of tooth preparation were analyzed to find a preparation method that resolved a baseline shift or slope in output signals of preliminary samples. Use of purity EDTA (ethylenedinitrilotetraacetic acid, disodium salt dihydrate) was initially found to reduce an observed baseline shift and slope in the output spectrum. Subsequent samples treated with EDTA, however, again saw baseline shifts. More needs to be done to analyze appropriate methodology to reduce the baseline shift, and to further determine the suitability of mouse teeth for ESR spectroscopy for reconstruction of lifetime dose

The Portrayal and Representation of Ed Kemper in Mind Hunter

The research conducted within this textual analysis study examined the portrayal and representation of Edmund Kemper in the Netflix show, Mind Hunter. Serial killers and their crimes have become a popular genre of media. This is a crucial topic to study because as the genre grows, misconceptions among serial killers may become more popular. Consumers who often consume this type of media end up bolstering a specific stereotype concerning serial killers. This research study analyzes the portrayal of this one specific individual. The researchers watched multiple viewings of the show and analyzed the representation of Kemper, specifically his physical appearance and characteristics, nonverbal and verbal communication. Kemper’s representation and portrayal in the show is aligned with multiple theories including, cultivation theory, feminist theories, masculinity theories and other previous literature conducted. We encourage further research to be conducted in regard to this show and other shows and films that focus on serial killers

Attainment and maintenance of pubertal cyclicity may predict reproductive longevity in beef heifers

We hypothesized the manner that heifers achieve puberty may indicate their future reproductive longevity. Heifers with discontinued or delayed cyclicity during puberty attainment may have irregular reproductive cycles, anovulation, and infertility in their first breeding season contributing to a shorter reproductive lifespan. Therefore, plasma progesterone (P4) was measured from weaning to breeding on 611 heifers born 2012–2017 and four pubertal classifications were identified: (1) Early; P4 ≥ 1 ng/ml \u3c March 12 with continued cyclicity, (2) Typical; P4 ≥ 1 ng/ml ≥ March 12 with continued cyclicity, (3) Start-Stop; P4 ≥ 1 ng/ml but discontinued cyclicity, and (4) Non-Cycling; no P4 ≥ 1 ng/ml. Historical herd records indicated that 25% of heifers achieved puberty prior to March 12th in the 10 years prior to the study. Start-Stop and Non-Cycling yearling heifers were lighter indicating reduced growth and reproductive maturity traits compared with Early/Typical heifers. In addition, Non-Cycling/Start-Stop heifers were less responsive to prostaglandin F2 alpha (PGF2α) to initiate estrous behavior and ovulation to be artificially inseminated. Non-Cycling heifers had fewer reproductive tract score-5 and reduced numbers of calves born in the first 21-days-ofcalving during their first breeding season. Within the Start-Stop classification, 50% of heifers reinitiated cyclicity with growth traits and reproductive parameters that were similar to heifers in the Early/Typical classification while those that remained non-cyclic were more similar to heifers in the Non-Cycling group. Thus, heifers with discontinued cyclicity or no cyclicity during puberty attainment had delayed reproductive maturity resulting in subfertility and potentially a shorter reproductive lifespan

Vascular Endothelial Growth Factor A 165 rescues steroids, inflammation and follicle arrest in High Androstenedione cows

A population of cows with excess androstenedione (A4; High A4) in follicular fluid, with follicular arrest, granulosa cell dysfunction, and a 17% reduction in calving rate was previously identified. We hypothesized that excess A4 in the ovarian microenvironment caused the follicular arrest in High A4 cows and that vascular endothelial growth factor A would rescue the High A4 phenotype. In trial 1, prior to culture, High A4 ovarian cortex (n=9) had greater numbers of early stage follicles (primordial) and fewer later-stage follicles compared to controls (n=11). Culture for 7 days did not relieve this follicular arrest; instead, High A4 ovarian cortex had increased indicators of inflammation, anti-Mullerian hormone, and A4 secretion compared to controls. In trial 2, we tested if vascular endothelial growth factor A (VEGFA) angiogenic (165) and antiangiogenic (VEGFA165b) isoforms could rescue the High A4 phenotype. High A4 (n=5) and control (n=5) ovarian cortex was cultured with (1) PBS, (2) VEGFA165 (50 ng/mL), (3) VEGFA165b (50 ng/mL), or (4) VEGFA165+VEGFA165b (50 ng/mL each) for 7 days. Follicular progression increased with VEGFA165 in High A4 cows with greater early primary, primary, and secondary follicles than controls. Similar to trial 1, High A4 ovarian cortex secreted greater concentrations of A4 and other steroids and had greater indicators of inflammation compared to controls. However, VEGFA165 rescued steroidogenesis, oxidative stress, and fibrosis. Both VEGFA isoforms reduced specific pro-inflammatory cytokines in High A4 cows to control levels. Thus, VEGFA165 may be a potential therapeutic to restore the ovarian steroidogenic microenvironment to promote folliculogenesis

Social Media Analysis of the Minnesota Wild

This original report analyzes the social media presence of hockey brand the Minnesota Wild. It critiques the brand\u27s use of social media by looking at their presence on different social media platforms, including, Facebook, Instagram, Twitter, and Pinterest. By examining current platform use, I identify what makes the Minnesota Wild different, how they gain followers, and specific strategies they use to engage their audience. The goal is to identify characteristics that differentiate this particular brand from its competitors. Along with that, I also analyze whether or not the current social media strategy they are using is working, or not, and how they can make it better in the future. Some strengths include the use of voice on platforms, engaging with their fans, a behind the scene look of the players, and making the players appear more authentic. Weaknesses for the Wild include, they are a younger brand, have a lot of competition in the NHL, they also do not have the same voice on every platform, and they are not using their Pinterest to its full potential. The Wild must find a balance between being genuine with their followers, and still being able to grow their brand following
