Saving The Children Of Shoreditch: Lady Cynthia Colville And Needy Families In East London, C.1900-1960, Kate Bradley

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

This article approaches the question of the 'child at risk' through the case of an elite individual who became involved in infant welfare and the juvenile courts: Lady Cynthia Colville. Colville entered into voluntary social work as an activity 'appropriate' for a woman of her standing. With her appointment as a lady-in-waiting to Queen Mary, the already very well-connected Colville had unrivalled access to the Royal Household for promoting the interests of her charities. The case of Colville provides a point of intersection for the historiographies on gender, class, welfare, and crime, and fresh insight into the relationship between 'innovation' …

The Child As Risk: Precocious Girls And Sexual Consent In Late Victorian Britain, Victoria Bates

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

The figure of the precocious girl pervaded Victorian culture, yet is poorly understood. This article focuses on concerns about sexual precocity and their influence on age-of-consent debates in the 1880s. It shows that even this single form of precocity (sexual) took multiple forms and was a malleable concept, often used selectively in parliamentary debates to suit particular agendas. These different uses of precocity did have in common, however, a tendency to be situated against the normal as 'ideal' rather than only statistically 'typical'. As precocity was generally measured against the ideal sexual development and behaviour of respectable North European girls, …

The Relationship Between Self-Esteem, Ambivalence, And Relationship Outcomes Within Romantic Partnerships, Victoria J. Schriber

Senior Independent Study Theses

The current study analyzes self-esteem and the apparent mood of one’s partner as predictors of perceived responsibility, level of felt rejection, and relationship satisfaction in romantic relationships. The study hypothesizes that ambivalence will act as a moderating variable between self-esteem and romantic relationship outcomes. Previous research on the topic suggests that self-esteem is associated with how participants react to their romantic partner when they are in a specific mood. The current study will be one of the first to examine how ambivalence affects self-esteem’s effect on romantic relationships. The results replicate previous research, showing that self-esteem interacts with partner’s mood …

Evidence Of A Perilipin 5 Splice Variant, Brodie Ranzau

Undergraduate Honors Thesis Projects

Alternative splicing occurs throughout the human genome, leading to multiple proteins from a single gene. The resulting proteins can be nearly identical or vastly different in how they function. Alternative splicing within the perilipin family has been observed in perilipins 1 and 3, giving rise to proteins with varying functions. In the course of our studies on perilipin 5, an immunoblot signal was observed that corresponded to an approximately 35 kDa protein. Western blot analysis of this protein has revealed its expression in C2C12 cultured myoblasts and in heart and liver mouse tissue. Further analysis of perilipin 5 cDNA through …

The free radicals can causing many diseases including heart diseases, Alzheimer, inflammation and cancer. This research aimed to investigate the effect of bioactive peptides derived from Synechococcus sp. cultured for 21 days on antioxidant, anti-inflammation and anticancer activities. The Synechococcus sp. protein hydrolysate was prepared by trypsin digest and purified by ultrafiltration with molecular weight cut off membranes of 10, 5 and 3 kDa. The MW <3 kDa fraction showed the highest NO, ABTS and DPPH radical scavenging activities with IC50 values of 34.51±9.8 µg protein/mL, IC50 11.54±0.3 µg protein/mL and IC50 13.63±0.15 µg protein/mL, respectively. The F2 fraction from gel filtration chromatography showed the strongest NO and ABTS radical scavenging activities with IC50 values of 7.68±0.64 µg protein/mL and 9.74±0.2 µg protein/mL, respectively. The F2 was purified by RP-HPLC to yield four fractions. The 30 – 40 min sub-fraction (F2-4) was selected for further analysis by mass spectroscopy. Five isolated peptides with amino acid sequences of AILQSYSAGKTK; 1,265.69 Da, ALNKTHLIQTK; 1,265.74 Da, LLVHAPVK; 875.55 Da, IPDAHPVK; 875.48 Da and VVVLRDGAVQQLGTPR; 1,706.97 Da were identified. The F2-4 had higher DPPH and NO radical scavenging activity compared to the synthetic peptide. Moreover, AILQSYSAGKTK had the highest ABTS radical scavenging activity. Furthermore, the F2 fraction protected oxidation-induced DNA damage in pBR322, pKS and pUC19 cells. F2 fraction was selected to study anti-inflammatory and anticancer properties. Anti-inflammatory effect, F2 fraction showed no cytotoxicity toward RAW264.7 macrophage cells. RT-PCR and qRT-PCR results showed that F2 reduced gene expression of pro-inflammatory cytokines iNOS, TNF-α, COX-1, COX-2 and IL-6. For anticancer activity, F2 fraction showed high anticancer activities in the human colon cancer cells (SW620) according to cytotoxic activity (MTT assay), with IC50 values of 106.58±21.46 µg protein/mL. The F2 fraction activated the apoptotic pathway in SW620 cells after treatment for 24, 48 and 72 hours. The highest activities of caspases 3, 8 and 9 were observed after treatment for 72 hours. These findings suggested that unicellular cyanobacterium Synechococcus sp. may be used to develop for natural anti-inflammation and natural anticancer drugs.
