We conducted a pilot study to assess the feasibility and acceptability of the app among participants in two cities in the southeastern United States.

Methods: Participants were recruited online and through community partners.

Landscape and prognostic significance of oncogene drivers in metastatic castration sensitive prostate cancer.

Background: Tumor suppressors are well known drivers of cancer invasion and metastasis in metastatic castration sensitive prostate cancer (mCSPC). However, oncogenes are also known to be altered in this state, however the frequency and prognosis of these alterations are unclear. Thus, we aimed to study the spectrum of oncogene mutations in mCSPC and study the significance of these alteration on outcomes.

Bladder sparing management for muscle-invasive bladder cancer after a complete clinical response: ready for prime time?-a narrative review.

Background And Objective: A standard of care for muscle-invasive bladder cancer (MIBC) is cisplatin-based neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC). Given recent improvements in NAC and the morbidity associated with RC, bladder-sparing therapy has been investigated as a promising treatment for patients with MIBC who experience a complete clinical response (CCR) to systemic therapy. However, clinical staging is unreliable, making it challenging to determine ideal candidates for bladder-sparing therapy.

Enriched class II HLA inherence in patients with checkpoint inhibitor-associated bullous pemphigoid.

Melanoma, with increasing annual incidence worldwide, is one of the deadliest cutaneous malignancies often treated with immunotherapy, which has led to commonly encountered immune-related adverse events (irAEs) including bullous pemphigoid (BP). The relation between an individual's HLA inheritance and risk in development of BP is well studied. The development of BP as an irAE in melanoma patients receiving immunotherapy is also well reported and considered to be related to the expression of BP180 in malignant melanoma.

Fluence-Dependent Photoinduced Charge Transfer Dynamics in Polymer-Wrapped Semiconducting Single-Walled Carbon Nanotubes.

Because an individual single-walled carbon nanotube (SWNT) can absorb multiple photons, the exciton density within a single tube depends upon excitation conditions. In SWNT-based energy conversion systems, interactions between excitons and charges make it possible for multiple types of charge transfer reactions. We exploit a SWNT-molecular donor-acceptor hybrid system (-PBN(b)-Ph-PDI-[(6,5) SWNT]) that fixes spatial organization and stoichiometry of perylene diimide (PDI) electron acceptors on the nanotube surface, to elucidate how excitation fluence affects ultrafast charge separation (CS) and the nature of charge recombination (CR) dynamics triggered upon SWNT near-infrared excitation.

The Heterotaxy Gene CCDC11 Is Important for Cytokinesis via RhoA Regulation.

Mutations in CCDC11 (cfap53) have been identified in multiple patients with heterotaxy (Htx), a disorder of left-right (LR) patterning of the internal organs. In Xenopus, depletion of Ccdc11 causes defects in LR patterning, recapitulating the patient phenotype. Upon Ccdc11 depletion, monociliated cells of the Left-Right Organizer (LRO) exhibit multiple cilia per cell.

The Associations Between Intimate Partner Violence and Mental Health Outcomes Among Sexual Minority Men: A Systematic Review and Meta-Analysis.

Sexual minority men (SMM) experience intimate partner violence (IPV) at a substantially high rate and also bear high burdens of adverse mental health outcomes. This systematic review and meta-analysis aimed to consolidate existing evidence on the associations between experiencing IPV and adverse mental health outcomes (depressive symptoms, anxiety, stress, etc.) among SMM.

Purpose: Gender minority (GM) stress, resulting from distal (i.e., external) and proximal (i.

Structural characterization of the POTRA domains from A. baumannii reveals new conformations in BamA.

Recent studies have demonstrated BamA, the central component of the β-barrel assembly machinery (BAM), as an important therapeutic target to combat infections caused by Acinetobacter baumannii and other Gram-negative pathogens. Homology modeling indicates BamA in A. baumannii consists of five polypeptide transport-associated (POTRA) domains and a β-barrel membrane domain.

Thr phosphorylation on RNA Pol II occurs at early transcription regulating 3'-end processing.

RNA polymerase II relies on a repetitive sequence domain (YSPTSPS) within its largest subunit to orchestrate transcription. While phosphorylation on serine-2/serine-5 of the carboxyl-terminal heptad repeats is well established, threonine-4's role remains enigmatic. Paradoxically, threonine-4 phosphorylation was only detected after transcription end sites despite functionally implicated in pausing, elongation, termination, and messenger RNA processing.

We aim to evaluate the prognostic significance as well as the genetic landscape of PIK3/Akt/mTOR pathway alteration in mCSPC.

Methods: Fourhundred and seventy-two patients with mCSPC were included who underwent next generation sequencing.

Cyclic Peptide Conjugate Vaccines and Physically Mixed Cyclic Peptide Vaccines for Subcutaneous Immunization.

Immune stimulants (adjuvants) enhance immune system recognition to provide an effective and individualized immune response when delivered with an antigen. Synthetic cyclic deca-peptides, co-administered with a toll-like receptor targeting lipopeptide, have shown self-adjuvant properties, dramatically boosting the immune response in a murine model as a subunit peptide-based vaccine containing group A Streptococcus peptide antigens.Here, we designed a novel peptide and lipid adjuvant system for the delivery of group A Streptococcus peptide antigen and a T helper peptide epitope.

Use of immune checkpoint inhibitors in solid organ transplant recipients with advanced cutaneous malignancies.

Background: Immune checkpoint inhibitors (ICI) are standard of care therapy for patients with cutaneous malignancies, the most frequently diagnosed cancers in solid organ transplant (SOT) recipients. The activity and rate of allograft rejection in SOT recipients with advanced skin cancers treated with ICI is understudied.

Methods: We conducted a retrospective analysis of SOT recipients with advanced melanoma, cutaneous squamous cell carcinoma (cSCC), and merkel cell carcinoma (MCC) who were treated with ICI.

Sexual Agreement Discussions Among Adolescent Sexual Minority Men in the USA.

Nearly two-thirds of new HIV infections are attributed to primary partners, necessitating a greater understanding of relationship context of HIV transmission among sexual minority men. Sexual agreements, which are the explicit decisions couples make about sexual behaviors allowed inside and outside of their relationship, have been primarily studied among adult sexual minority men. Little work has sought to understand how adolescent sexual minority men utilize and navigate sexual agreement conversations.
