A paper-based HPV E7 oncoprotein assay for cervical precancer detection at the point of care.

Cervical cancer, while preventable through screening and treatment of cervical precancer, remains a global challenge with a disproportionately high burden of disease in resource-limited settings, especially in low- and middle-income countries (LMICs). Lack of affordable, easy-to-use screening and diagnostic tests contributes to this disparity. Most commercially available tests are not appropriate for use in LMICs due to resource constraints.

Dynamic soil columns simulate Arctic redox biogeochemistry and carbon release during changes in water saturation.

Thawing Arctic permafrost can induce hydrologic change and alter redox conditions, shifting the balance of soil organic matter (SOM) decomposition. There remains uncertainty about how soil saturation and redox transitions impact dissolved and gas phase carbon fluxes, and efforts to link hydrobiogeochemical processes to ecosystem-scale models are limited. This study evaluates SOM decomposition of Arctic tundra soils using column experiments, water chemistry measurements, microbial community analysis, and a PFLOTRAN reactive transport model.

A Call for a Neoadjuvant Kidney Cancer Consortium: Lessons Learned from Other Cancer Types.

Neoadjuvant systemic treatment strategies have improved outcomes in several solid tumour types. This success has not yet been replicated in renal cell carcinoma (RCC). A consensus and international collaboration are urgently needed for the development of adaptive perioperative immunotherapy strategies for patients with RCC at high risk of recurrence.

Background: Understanding gene-environment interactions associated with vitamin D status may refine nutrition and public health strategies for vitamin D deficiency. Recent methodological advances have enabled the identification of variance quantitative trait loci (vQTLs) where gene-environment interactions are enriched.

Objectives: To identify vQTLs for serum 25-hydroxy vitamin D (25OHD) concentrations and characterize potential gene-environment interactions of vQTLs.

End-of-pipe filter to reduce phosphorus concentrations from the effluent of green infrastructure underdrains.

Green stormwater infrastructure is growing in adoption across the world due to its ability to capture and treat stormwater runoff at the source; however, while green stormwater infrastructure is effective at reducing the concentration of many priority pollutants, bioretention often increases the concentration of dissolved phosphorus in the stormwater it treats. This is a significant shortcoming, as dissolved phosphorus can promote algae growth in receiving water bodies resulting in negative impacts to human and aquatic health. This study seeks to address this shortcoming through an end-of-pipe filter at the end of bioretention effluent pipes designed to reduce the concentration of dissolved phosphorus.

Presentation and Surgical Outcomes of Primary Hyperparathyroidism After Radioactive Iodine Therapy.

Background: Radioactive iodine (RAI) is a common treatment for various thyroid diseases. Previous studies have suggested susceptibility of parathyroid glands to the mutagenic effect of RAI and the development of primary hyperparathyroidism (PHPT). We tested the possible link between prior RAI treatment, disease presentation, and treatment outcomes.

Association between pituitary adenoma consistency, resection techniques, and patient outcomes: a single-institution experience.

Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.

Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.

The Fit Older Adult with Acute Myeloid Leukemia: Clinical Challenges to Providing Evidence-Based Frontline Treatment.

Recent advances in acute myeloid leukemia (AML) come from studies investigating younger (age<60 years) adults or older (age≥75 years) or less fit adults. Uncertainty exists for the management of otherwise healthy adults with AML in their 60s and 70s, which also represents a significant proportion of AML cases. We discuss current considerations in older, fit adults with AML including determination of fitness, what factors beyond fitness should be assessed, and finally what challenges and innovations lie ahead to improve outcomes for these patients.

Review on the o-aminoaniline Moiety in Peptide and Protein Chemistry.

Peptides and proteins are important functional biomolecules both inside and outside of living organisms. The ability to prepare various types of functionalized peptides and proteins is essential for understanding fundamental biological processes, such as protein folding and post-translational modifications (PTMs), and for developing new therapeutics for many diseases, such as cancers and neurodegenerative diseases. The o-aminoaniline moiety was first proposed for activation to a thioester precursor and used for native chemical ligation to prepare large peptides and proteins.

Polygenic risk discriminates Lewy body dementia from Alzheimer's disease.

Introduction: Lewy body dementia (LBD) shares genetic risk factors with Alzheimer's disease (AD), including apolipoprotein E (APOE), but is distinguishable at the genome-wide level. Polygenic risk scores (PRS) may therefore improve diagnostic classification.

Methods: We assessed diagnostic classification using AD-PRS excluding APOE (AD-PRS ), APOE risk score (APOE-RS), and plasma phosphorylated tau 181 (p-tau181), in 83 participants with LBD, 27 with positron emission tomography amyloid beta (Aβ)positive mild cognitive impairment or AD (MCI+/AD), and 57 controls.

Relational encoding promotes creative insight for problem-solving.

The nature and basis of creative thought has been the subject of wide-ranging inquiry. It is well established that people tend to struggle to solve problems that require an insight-and that this limitation is not readily alleviated. What can help produce more successful creative cognition? We propose a benefit from increased focus on the relations that hold between the elements of a problem situation.
