The Art Of Masking And Performing For The Perfect Marriage In William Shakespeare’S The Taming Of The Shrew, Rita Oliva

Dissertations and Theses

This thesis explores how William Shakespeare’s The Taming of the Shrew exaggerates the art of masking and performing as necessary social techniques for women surviving the patriarchal culture of Padua. Through close analysis of Katherine and Bianca Minola, both sisters adopt performative identities, the “shrew” and the “ideal woman,” that reflect, resist, and expose the restrictive gender norms governing female behavior, qualifications for marriage, and worth. While Bianca’s apparent passivity and rhetorical femininity promote her to manipulate societal expectations to her advantage, Katherine’s refusal to submit to the societal and cultural standards of Padua results in her categorization of a …

Investigation Of Rna-Binding Protein Expression Changes In The Hippocampus Following Doxorubicin And Cyclophosphamide Treatment, Lijie Chen

Dissertations and Theses

This study investigated the molecular mechanisms underlying chemotherapy-induced cognitive impairment (CICI) following doxorubicin and cyclophosphamide treatment in a rat model, revealing three significant alterations in hippocampal tissue: selective downregulation of heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) (21% decrease, p=0.0298), compromised astrocytic network integrity evidenced by reduced GFAP-positive area in cornu ammonis 3 (CA3) (24%, pB=0.026) and dentate gyrus (DG) (19%, pB=0.027) regions, and elevated cellular senescence marker p19Arf specifically in DG (69%, pB=0.033) and CA3 (27%, pB=0.024). The inverse relationship between hnRNPA1 reduction and p19Arf elevation suggests a potential mechanistic link between RNA dysregulation and senescence induction, with pronounced vulnerability in …

Toxin-Like Proteins In The Venom Of Drosophila Parasitoids, Lady V. Cardenas

Dissertations and Theses

The figitid parasitoid wasps of Drosophila are gaining importance in agriculture due to their ability to kill the resilient soft-fruit pest Drosophila suzukii. Their success and infection strategies vary, and the mechanisms underlying these differences are largely unknown. Some of their venom proteins have been shown to be important in suppressing host defense. Here, we report that Ganaspis brasiliensis, a parasitoid of D. suzukii survives well on Drosophila yakuba, a host species with a strong cellular immunity, and infected flies are unable to mount a strong immune response. To predict possible toxin-like proteins in Ganaspis venoms that might suppress cellular …

Adaptation Of The Biodent For Spherical Microindentation To Determine Elastic Modulus In Small Rodent Bones, Mixame E. Jerome

Dissertations and Theses

Mechanical and material properties of bone are essential for understanding both normal skeletal function and the progression of bone-related diseases. Microindentation has become a widely used method for evaluating tissue mechanical properties of bone, as it samples the contributions of microarchitecture and composition. Microindentation using a standard pointed tip inherently introduces both elastic and plastic deformation into the material. In contrast, indentation with a spherical tip can be operated entirely in the elastic range, providing for a non-damaging test that has significant advantages over sharp indentation techniques. Moreover, a key advantage of using spherical indentation lies in its operation under …
