Long-Term Urinary and Sexual Outcomes in Pediatric Genitourinary Rhabdomyosarcoma Survivors: A Qualitative Study.

Purpose: Genitourinary rhabdomyosarcoma (GU-RMS) often requires multimodal therapy treatment including radiation, chemotherapy, and radical surgery for disease control. The long-term effects of the disease and associated treatments are unclear. We sought to investigate the long-term genitourinary quality of life for adult survivors of pediatric GU-RMS.

The roles of cognitive dissonance and normative reasoning in attributions of minds to robots.

As a wide variety of intelligent technologies become part of everyday life, researchers have explored how people conceptualize agents that in some ways act and think like living things but are clearly machines. Much of this work draws upon the idea that people readily default to generalizing human-like properties to such agents, and only pare back on these generalizations with added thought. However, recent findings have also documented that people are sometimes initially hesitant to attribute minds to a machine but are more willing to do so with additional thought.

The development of surgical ability during pediatric urology fellowship and its evolution in the early years of practice.

Background: North American Pediatric Urology fellowship programs underwent a structural change in 2021 that allows more flexibility in training. Given this opportunity as well as widespread concern about the development of contemporary surgical trainees, it is prudent to understand in detail the current state of preparedness of pediatric urology fellowship graduates for independent practice.

Objective: The study aimed to determine recent pediatric urology graduates' reported levels of comfort both at graduation and following the start of clinical practice in performing select index procedures.

Remembering conversation in group settings.

Individuals can take on various roles in conversation. Some roles are more active, with the participant responsible for guiding that conversation in pursuit of the group's goals. Other roles are more passive, like when one is an overhearer.

When searching helps you see: Bridging the gap between incidental and intentional change detection.

Participants in incidental change detection studies often miss large changes to visually salient or conceptually relevant objects such as actor substitutions across video cuts, but there are competing explanations of why participants fail to detect these changes. According to an integrative processing account, object-based attention typically induces integrated representation and comparison processes sufficient to detect changes to that object. On this view, participants miss changes in incidental paradigms because those paradigms fail to elicit the level of attention necessary to trigger integrated representation and comparison processes.

MEMCONS: How Contemporaneous Note-Taking Shapes Memory for Conversation.

Written memoranda of conversations, or memcons, provide a near-contemporaneous record of what was said in conversation, and offer important insights into the activities of high-profile individuals. We assess the impact of writing a memcon on memory for conversation. Pairs of participants engaged in conversation and were asked to recall the contents of that conversation 1 week later.

Video speeding can be efficient and speeding-induced preference cost can be lessened by selective speeding.

Over the past decade, screen-captured instructional videos have become popular tools for learning. Viewers wanting to learn efficiently can play these videos at faster-than-normal speeds, a feature offered by hosting services such as YouTube. Although previous research suggests that moderate speeding may not lessen learning, little research has tested this form of media for speeding-induced learning impairments.

Results: Of the 143 patients treated for FG at our institution, 33 (23%) were female.

The interrelationship between concepts about agency and students' use of teachable-agent learning technology.

To successfully interact with software agents, people must call upon basic concepts about goals and intentionality and strategically deploy these concepts in a range of circumstances where specific entailments may or may not apply. We hypothesize that people who can effectively deploy agency concepts in new situations will be more effective in interactions with software agents. Further, we posit that interacting with a software agent can itself refine a person's deployment of agency concepts.

The Selective PI3K Inhibitor XL147 (SAR245408) Inhibits Tumor Growth and Survival and Potentiates the Activity of Chemotherapeutic Agents in Preclinical Tumor Models.

Dysregulation of PI3K/PTEN pathway components, resulting in hyperactivated PI3K signaling, is frequently observed in various cancers and correlates with tumor growth and survival. Resistance to a variety of anticancer therapies, including receptor tyrosine kinase (RTK) inhibitors and chemotherapeutic agents, has been attributed to the absence or attenuation of downregulating signals along the PI3K/PTEN pathway. Thus, PI3K inhibitors have therapeutic potential as single agents and in combination with other therapies for a variety of cancer indications.

Diffuse large B-cell lymphoma in an adolescent male presenting as ureteral stricture.

Lymphoma may affect the ureter in cases of retroperitoneal involvement. We present a case of an adolescent male found to have non-Hodgkin lymphoma initially presenting as ureteral stricture evident on imaging. He was treated and responded to multiagent chemotherapy with resolution of both the lymphoma and the ureteral stricture.

Characterization of the activity of the PI3K/mTOR inhibitor XL765 (SAR245409) in tumor models with diverse genetic alterations affecting the PI3K pathway.

Activation of the PI3K (phosphoinositide 3-kinase) pathway is a frequent occurrence in human tumors and is thought to promote growth, survival, and resistance to diverse therapies. Here, we report pharmacologic characterization of the pyridopyrimidinone derivative XL765 (SAR245409), a potent and highly selective pan inhibitor of class I PI3Ks (α, β, γ, and δ) with activity against mTOR. Broad kinase selectivity profiling of >130 protein kinases revealed that XL765 is highly selective for class I PI3Ks and mTOR over other kinases.

Patients were then matched according to preoperative transrectal ultrasound prostate size to 74 patients without prior surgery who underwent HoLEP (group II).

Discovery of XL888: a novel tropane-derived small molecule inhibitor of HSP90.

With structural guidance, tropane-derived HTS hits were modified to optimize for HSP90 inhibition and a desirable in vivo profile. Through an iterative SAR development process 12i (XL888) was discovered and shown to reduce HSP90 client protein content in PD studies. Furthermore, efficacy experiments performed in a NCI-N87 mouse xenograft model demonstrated tumor regression in some dosing regimens.

Discovery of a novel series of potent and orally bioavailable phosphoinositide 3-kinase γ inhibitors.

The phosphoinositide 3-kinases (PI3Ks) have been linked to an extraordinarily diversified group of cellular functions making these enzymes compelling targets for the treatment of disease. A large body of evidence has linked PI3Kγ to the modulation of autoimmune and inflammatory processes making it an intriguing target for drug discovery. Our high-throughput screening (HTS) campaign revealed two hits that were nominated for further optimization studies.
