Applications of Verdazyl Radicals in Energy Storage, Molecular Electronics and Magnetism: Teaching Old Molecules New Tricks.

Verdazyls are a fundamental class of stable organic radicals that have been traditionally overshadowed by the more synthetically accessible stable nitroxide radicals. With the advent of enhanced synthetic routes to verdazyls, particularly in recent years, these systems are now poised to realise their potential in a range of applications across emerging technologies that will be important to addressing challenges faced by modern society. This Concept discusses the enabling properties of a selection of verdazyl-based systems that feature promising applications in energy storage, molecular electronics and magnetic molecules.

Invasive Fungal Diseases in Patients with Multiple Myeloma: Experience at a Large, Urban Referral Center.

Background: Although infections are a leading cause of morbidity and mortality among patients with multiple myeloma (MM), the epidemiology of invasive fungal disease (IFD) is less well characterized in this population than in other hematologic malignancies.

Methods: We conducted a nested 3:1 case-control study of IFD at a large MM referral center to identify risk factors for IFD in this population.

Results: In a cohort of 2960 patients, we identified 32 episodes of IFD among 31 patients between 01/2011 and 06/2019.

Bone Erosions and Systemic Bone Loss on HR-pQCT in Men With Tophaceous Gout.

Aims: Gout, a prevalent inflammatory arthropathy, predominantly affects males and arises from persistent hyperuricemia, resulting in monosodium urate crystal deposition. Hyperuricemia is associated with comorbidities, exacerbating patient morbidity. Conflicting literature exists regarding uric acid's impact on bone mineral density (BMD), with potential proinflammatory effects in gout patients.

Radiographic and Clinical Outcomes of First Tarsometatarsal Joint Arthrodesis With a Biplanar Locking Plate System Versus the Modified Lapidus Technique With Crossed-Screw Fixation: A Retrospective Multicenter Comparison.

: Hallux valgus (HV) is recognized as a triplanar deformity. A biplanar locking plate (BLP) system corrects this deformity through first tarsometatarsal joint (TMTJ) arthrodesis, with specialized reduction tools and cutting guides. Yet the optimal surgical technique and fixation construct for first TMTJ arthrodesis remains controversial.

Clinical predictors of recurrent cholecystitis in non-operative management: A systematic review & meta-analysis.

Introduction: Gallstone disease is prevalent and carries substantial implications for morbidity and healthcare resource utilization. While early laparoscopic cholecystectomy (LC) is often preferred, its feasibility may be limited in some cases. As a result, many patients undergo conservative management.

Immediate Loading Full-Arch 3D-Printed Implant-Supported Fixed Rehabilitation: A Case Report with 24-Month Follow-Up.

Implant-supported immediate loading full-arch rehabilitation has been documented in the literature. More recently, computed surgical guides have frequently been used since they facilitate planning and performing surgical treatment without the need to raise a flap, thus reducing trauma and morbidity. This case report describes an immediate full-arch, fixed rehabilitation with full loading placed on four commercially available 3D-printed implants, with a 24-month follow-up.

Distinctive and highly variable bird migration system revealed in Eastern Australia.

Our understanding of bird migration is heavily biased toward long-distance movements in the Northern Hemisphere, with only fragmented knowledge from the Southern Hemisphere. In Australia, while some species migrate, the timing and direction of large-scale, multi-species seasonal movements remain critically understudied due to the complexity of movement in this region and a lack of research personnel and infrastructure. It is still unclear whether there are pronounced and structured mass movements resembling those in the Northern Hemisphere.

A Comprehensive Review of the Antitumor Properties and Mechanistic Insights of Duocarmycin Analogs.

The duocarmycin family is a group of potent cytotoxic agents originally isolated from the bacterium Streptomyces. This discovery has spurred significant interest due to duocarmycins' unique chemical structures and powerful mechanism of action. This review comprehensively details the history of the duocarmycin family, the current understanding of their therapeutic potential, and the major clinical trials that have been conducted.

Synthesis, Structure, and Redox Properties of Nonsymmetric 6-Oxoverdazyls.

Nonsymmetric 6π-electron ("oxidized") 6-oxoverdazyls have been synthesized for the first time. After formal incorporation of a hydrogen atom, the corresponding 7π-electron neutral verdazyl radical is generated. The 7π radical can undergo a further electrochemically reversible reduction to an 8π anion.

Immunotherapeutic potential of collagen V oral administration in mBSA/CFA-induced arthritis.

We hypothesized that after synovial injury, collagen V (Col V) expose occult antigens, and Col V autoantibodies develop, indicating the loss of immune tolerance against this molecule, thus leading to damage to mesenchymal-derived cells as well as the extracellular matrix in experimental arthritis. Thus, the present study investigated the effects of oral administration of Col V on the synovium after the development of inflammation in mBSA/CFA-induced arthritis. After fourteen days of intraarticular administration of mBSA, 10 male Lewis rats were orally administered Col V (500 μg/300 μL) diluted in 0.

A Snapshot of Lead in Consumer Products Across Four US Jurisdictions.

Background: Following the removal of lead from gasoline, paint and pipes were thought to be the main sources of lead exposure in the United States. However, consumer products, such as certain spices, ceramic and metal cookware, traditional health remedies, and cultural powders, are increasingly recognized as important sources of lead exposure across the United States.

Objective: This paper reviews data from four US jurisdictions that conduct in-home investigations for children with elevated blood lead levels (BLLs) to examine the prevalence of lead exposures associated with consumer products, in comparison with housing-related sources.

Small non-coding RNAs and pancreatic ductal adenocarcinoma: Linking diagnosis, pathogenesis, drug resistance, and therapeutic potential.

This review comprehensively investigates the intricate interplay between small non-coding RNAs (sncRNAs) and pancreatic ductal adenocarcinoma (PDAC), a devastating malignancy with limited therapeutic options. Our analysis reveals the pivotal roles of sncRNAs in various facets of PDAC biology, spanning diagnosis, pathogenesis, drug resistance, and therapeutic strategies. sncRNAs have emerged as promising biomarkers for PDAC, demonstrating distinct expression profiles in diseased tissues.

miRNA signatures underlie chemoresistance in the gemcitabine-resistant pancreatic ductal adenocarcinoma cell line MIA PaCa-2 GR.

Chemotherapy resistance remains a significant challenge in the treatment of pancreatic adenocarcinoma (PDAC), particularly in relation to gemcitabine (Gem), a commonly used chemotherapeutic agent. MicroRNAs (miRNAs) are known to influence cancer progression and chemoresistance. This study investigates the association between miRNA expression profiles and gemcitabine resistance in PDAC.

The concern over the consequences of chemical exposures at the global level continues to grow. Because resources are constrained, there is a need to prioritize interventions focused on the greatest health impact.

The Effect of Shift Timing on Cesarean Delivery Outcomes and Operative Noise Levels.

Objective:  Intraoperative noise exposure has been associated with an increased risk of complications, communication errors, and stress among surgical team members. This study evaluates intraoperative noise levels in cesarean deliveries during different shift times, for example, night shifts, day shifts, and hand-off times between shifts.

Study Design:  This is a secondary analysis of a prospective observational study which measured volume in decibels, percentage of time above safe levels (>60 dB), startle noise events (events with rapid increase of decibel level above baseline noise), and peak levels (>75 dB) for cesarean deliveries during a 3-month preintervention and postintervention study.

A Rare Case of Transient Mesenteric Ischemia After Atrial Fibrillation With Rapid Ventricular Response Rate.

Mesenteric ischemia is an urgent event and requires prompt recognition and treatment, in order to reduce the risk of mortality. It results from the sudden onset of small intestinal hypoperfusion, from a reduction or cessation of arterial perfusion, which can occur from an embolic obstruction at the superior mesenteric artery. We present a case of transient mesenteric ischemia from an episode of atrial fibrillation with a rapid ventricular response rate.
