Background: Recurrent respiratory papillomatosis (RRP) is a rare debilitating condition caused by chronic infection with human papillomavirus (HPV) type 6 or 11. Papillomas develop in the aerodigestive tract, leading to significant voice disturbance and airway obstruction. No systemic treatment currently exists.

The selectivity for less reactive amines over competing alcohols was achieved using TCFH and catalytic Oxyma as a highly reactive, inexpensive, and safe reagent combination. By temporarily masking more reactive amines as imines through the use of electron-deficient aldehydes, the hindered amines could be similarly coupled with high efficiency and selectivity.

Reliable population-based data is critical to understand the magnitude and nature of the problem, and inform evidence-based prevention.
Objective: To determine the prevalence of nonconsensual sharing of sexual images of the child by any perpetrator, and of online sexual solicitation by any adult perpetrator; and to determine the characteristics of these experiences.
The therapeutic efficacy of donor lymphocyte infusions (DLIs) given after allogeneic hematopoietic cell transplantation (HCT) is limited by risk of graft-versus-host disease (GVHD). Post-transplantation cyclophosphamide (PTCy) effectively prevents severe GVHD, but there are limited data on outcomes of DLIs given to PTCy-treated patients. We reviewed 162 consecutive PTCy-treated patients transplanted between 2015-2022 within the Center for Immuno-Oncology at the National Cancer Institute.

The time-relative interest account (TRIA) of harm and wrongdoing tells us that a necessary condition for harming someone is that his or her time-relative interests are frustrated. Regarding the justification for abortion, this account falls prey to impairment arguments.

In the context of induced pancreatic endocrine cell implantation, previous studies have reported graft enlargement resulting from off-target pancreatic lineage cells. However, there is currently no documented evidence of proliferative off-target cells beyond the pancreatic lineage in existing studies.

Design: A systematic review following Joanna Briggs Institute methodology.
Methods: The review included empirical studies that involved older nurses as the primary study population and studies that focused on ageism in older nurses' work environments, including strategies or interventions to address ageism within the workplace.
Current differentiation protocols for human induced pluripotent stem cells (hiPSCs) produce heterogeneous cardiomyocytes (CMs). Although chamber-specific CM selection using cell surface antigens enhances biomedical applications, a cell surface marker that accurately distinguishes between hiPSC-derived atrial CMs (ACMs) and ventricular CMs (VCMs) has not yet been identified. We have developed an approach for obtaining functional hiPSC-ACMs and -VCMs based on CD151 expression.

This study aimed to describe the experiences and perspectives of children and young people living with cSLE. An integrative review guided by Whittemore and Knafl was conducted.
View Article and Find Full Text PDFLive streaming of child sexual abuse (CSA) involves the procurement and viewing of sexual abuse of children across the internet in real time, in exchange for money. These offenses leave little tangible evidence of the offense beyond a financial transaction, and metadata relating to the live-streaming session. This research analyzed the demographic, criminal history, and financial transaction characteristics of 209 individuals who live streamed child sexual abuse.

The number of Pacific people aged ≥65 years in Aotearoa New Zealand will increase significantly over the next decade. Addressing the considerable health inequities and unmet need for care Pacific Island people experience when compared to other ethnicities in Aotearoa New Zealand should be a priority.

Objective: To identify whether increasing glottic dysplasia severity is associated with higher local malignant transformation rates or adverse clinical outcomes.
This study describes a novel series of UDP--acetylglucosamine acyltransferase (LpxA) inhibitors that was identified through affinity-mediated selection from a DNA-encoded compound library. The original hit was a selective inhibitor of LpxA with no activity against LpxA. The biochemical potency of the series was optimized through an X-ray crystallography-supported medicinal chemistry program, resulting in compounds with nanomolar activity against LpxA (best half-maximal inhibitory concentration (IC) <5 nM) and cellular activity against (best minimal inhibitory concentration (MIC) of 4 μg/mL).
View Article and Find Full Text PDFOne of the earliest maturation steps in cardiomyocytes (CMs) is the sarcomere protein isoform switch between TNNI1 and TNNI3 (fetal and neonatal/adult troponin I). Here, we generate human induced pluripotent stem cells (hiPSCs) carrying a TNNI1 and TNNI3 double reporter to monitor and isolate mature sub-populations during cardiac differentiation. Extensive drug screening identifies two compounds, an estrogen-related receptor gamma (ERRγ) agonist and an S-phase kinase-associated protein 2 inhibitor, that enhances cardiac maturation and a significant change to TNNI3 expression.

Technologies for effective litter odor control have not been rigorously evaluated. Here, we report on the effectiveness of a novel litter formulation of 1-monochlorodimethylhydantoin (MCDMH)-modified clinoptilolite zeolite (MCDMH-Z) to control the odors of 3-mercapto-3-methylbutanol (3M3MB) and ammonia, the principal products generated by the enzymatic breakdown of felinine and urea, respectively.

Objective: To explore the barriers to communities in New Zealand developing age-friendly initiatives.
Methods: A qualitative participatory approach underpinned this study. Semi-structured digitally recorded individual interviews were undertaken with 24 government officials, local government steering group members and community representatives from an urban city, provincial city and a rural district.
Objective: Explore how older adults' talk about accessing rural community health services.
Methods: A qualitative narrative gerontological approach explored issues related to accessing health services in their community. Semi-structured digitally recorded individual interviews were undertaken with 32 community-dwelling older people aged between 75 and 93 years.

Globally, numbers of people aged 85 years and over are increasing. Many older people, including those 85 years and over, are ageing in rural areas. For successful ageing in place, physical and social environments must be appropriate.

Objectives: to evaluate the impacts of involving older people in health and social care research on older co-researchers, academic researchers, and research processes and outcomes. A secondary aim was to explore critical success factors and future considerations for PPI.
