Bacterial Outer Membrane Vesicles Provide An Alternative Pathway For Trafficking Of Escherichia Coli O157 Type Iii Secreted Effectors To Epithelial Cells, Natalie Sirisaengtaksin, Eloise J O'Donoghue, Sara Jabbari, Andrew J Roe, Anne Marie Krachler

Outer membrane vesicles (OMVs) are proteoliposomes shed by Gram-negative bacteria. Their secretion is enhanced by the transition into the intra-host milieu, and OMVs play critical roles during pathogenesis. Enterohemorrhagic Escherichia coli O157 (EHEC) can cause diarrheal disease in humans, and soluble toxins including Shiga-like toxins that contribute to disease severity and clinical complications like hemolytic uremic syndrome have been shown to be OMV associated. In addition to Shiga-like toxins, EHEC produces a type III secretion system (T3SS), and T3SS effectors are associated with colonization and disease severity in vivo. Here, we show that type III secreted substrates including translocators …

Although inflammatory bowel diseases are on the rise, what factors influence IBD risk and severity, and the underlying mechanisms remain to be fully understood. Although host genetics, microbiome, and environmental factors have all been shown to correlate with the development of IBD, cause and effect are difficult to disentangle in this context. For example, AIEC is a known pathobiont found in IBD patients, but it remains unclear if gut inflammation during IBD facilitates colonization with AIEC, or if AIEC colonization makes the host more susceptible to pro-inflammatory stimuli. It is critical to understand the mechanisms that contribute to AIEC infections …

Disrupting Perceptions Of Color Blindness As The Norm: Children’S Talk About Race, Grace Reid
Disrupting Perceptions Of Color Blindness As The Norm: Children’S Talk About Race, Grace Reid
Arts & Sciences Graduate Student Theses and Dissertations
Talking about race can improve children’s ethnic identities, prepare them for encounters with racism, and reduce their racial biases. Yet adults hold intuitive beliefs (e.g., children do not notice race) that limit their conversations about race with children. Children can also initiate conversations about race, but children have been found to avoid talking about race by 10 years. It has been suggested that children avoid talking about race because of colorblind norms, but children’s reasoning about color blindness as a norm is not well understood. Even less is known about the conditions under which children will talk about race. Across …
Characterization Of 3d Printed Lattice Structures Used In The Design Of Modified Compression Release Stabilized Transhumeral Prosthetic Sockets, Jade Myers
Theses
Abstract A prosthetic socket is the critical interface between a person and their prosthetic device. Pressure, shear, and friction experienced by the residual limb from wearing a socket can damage soft tissue. While Compression Release Stabilized (CRS) style sockets are beneficial for enhancing prosthesis stability, range of motion, and control, the abrupt differences in compression throughout the socket present risks for tissue damage to the residual limb. A socket design that enables clinicians to control a progressive decrease in firmness in the transition areas between compression and release could mitigate such undesirable effects. Density-graded lattice structures designed and produced with …
Shock-Wave Tolerant Phase Reconstruction Algorithm For Shack–Hartmann Wavefront Sensor Data, Thomas E. Defoor, Matthew Kalensky, Matthew R. Kemnetz, Timothy J. Bukowski, Mark F. Spencer
Shock-Wave Tolerant Phase Reconstruction Algorithm For Shack–Hartmann Wavefront Sensor Data, Thomas E. Defoor, Matthew Kalensky, Matthew R. Kemnetz, Timothy J. Bukowski, Mark F. Spencer
Faculty Publications
We develop a phase reconstruction algorithm for the Shack–Hartmann wavefront sensor (SHWFS) that is tolerant to phase discontinuities, such as the ones imposed by shock waves. In practice, this algorithm identifies SHWFS locations where the resultant tilt information is affected by the shock and improves the tilt information in these locations using the local SHWFS observation-plane irradiance patterns. The algorithm was shown to work well over the range of conditions tested with both simulated and experimental data. In turn, the reconstruction algorithm will enable robust wavefront sensing in transonic, supersonic, and hypersonic environments.

Surface chemistry of materials that host quantum bits such as diamond is an important avenue of exploration as quantum computation and quantum sensing platforms mature. Interfacing diamond in general and nanoscale diamond (ND) in particular with silica is a potential route to integrate room temperature quantum bits into photonic devices, fiber optics, cells, or tissues with flexible functionalization chemistry. While silica growth on ND cores has been used successfully for quantum sensing and biolabeling, the surface mechanism to initiate growth was unknown. This report describes the surface chemistry responsible for silica bond formation on diamond and uses X-ray absorption spectroscopy …

Loot boxes are purchasable randomized rewards in video games that share structural and psychological similarities with gambling. Systematic review evidence has established reproducible associations between loot box purchasing and both problem gambling and problem video gaming, perhaps driven by a range of overlapping psychological processes (e.g. impulsivity, gambling-related cognitions, etc.) It has also been argued that loot box engagement may have negative influences on player financial and psychological wellbeing. We conducted a pre-registered survey of 1495 loot box purchasing gamers (LB cohort) and 1223 gamers who purchase other, non-randomized game content (nLB cohort). Our survey confirms 15 of our 23 …

Feedforward haptic feedback methods are described herein. One example method is performed while an artificial-reality user interface (UI) is presented with a target UI object, a background UI portion, and one other UI object. If a representation of a body part of the user on which the wearable device is worn is within the background UI portion, the method includes providing a first haptic feedback. If the representation of the body part of the user is over the one other UI object, the method further includes providing a second haptic feedback indicating that the representation of the body part is …
