Evidence of nitrate-based nighttime atmospheric nucleation driven by marine microorganisms in the South Pacific.

Our understanding of ocean-cloud interactions and their effect on climate lacks insight into a key pathway: do biogenic marine emissions form new particles in the open ocean atmosphere? Using measurements collected in ship-borne air-sea interface tanks deployed in the Southwestern Pacific Ocean, we identified new particle formation (NPF) during nighttime that was related to plankton community composition. We show that nitrate ions are the only species for which abundance could support NPF rates in our semicontrolled experiments. Nitrate ions also prevailed in the natural pristine marine atmosphere and were elevated under higher sub-10 nm particle concentrations.

Evaluating DFHBI-Responsive RNA Light-Up Aptamers as Fluorescent Reporters for Gene Expression.

Protein-based fluorescent reporters have been widely used to characterize and localize biological processes in living cells. However, these reporters may have certain drawbacks for some applications, such as transcription-based studies or biological interactions with fast dynamics. In this context, RNA nanotechnology has emerged as a promising alternative, suggesting the use of functional RNA molecules as transcriptional fluorescent reporters.

Real-world clinical effectiveness of sorafenib among patients with unresectable hepatocellular carcinoma at two centers in the United States.

Background: In the United States, sorafenib monotherapy was approved in 2007 for first-line (1L) treatment of patients with unresectable hepatocellular carcinoma (uHCC). As other therapies have been approved in recent years for hepatocellular carcinoma treatment in later lines, it is essential to assess clinical effectiveness of older therapies in actual clinical practice to inform healthcare practitioners' decisions for better patient care.

Aim: To assess patient characteristics/clinical effectiveness of 1L sorafenib in uHCC patients treated in United States academic and community practice settings.

DTI-MR fingerprinting for rapid high-resolution whole-brain T , T , proton density, ADC, and fractional anisotropy mapping.

Purpose: This study aims to develop a high-efficiency and high-resolution 3D imaging approach for simultaneous mapping of multiple key tissue parameters for routine brain imaging, including T , T , proton density (PD), ADC, and fractional anisotropy (FA). The proposed method is intended for pushing routine clinical brain imaging from weighted imaging to quantitative imaging and can also be particularly useful for diffusion-relaxometry studies, which typically suffer from lengthy acquisition time.

Methods: To address challenges associated with diffusion weighting, such as shot-to-shot phase variation and low SNR, we integrated several innovative data acquisition and reconstruction techniques.

Induced pluripotent stem cells derived from patients carrying mitochondrial mutations exhibit altered bioenergetics and aberrant differentiation potential.

Background: Human mitochondrial DNA mutations are associated with common to rare mitochondrial disorders, which are multisystemic with complex clinical pathologies. The pathologies of these diseases are poorly understood and have no FDA-approved treatments leading to symptom management. Leigh syndrome (LS) is a pediatric mitochondrial disorder that affects the central nervous system during early development and causes death in infancy.

PGF2α signaling drives fibrotic remodeling and fibroblast population dynamics in mice.

Idiopathic pulmonary fibrosis (IPF) is a chronic parenchymal lung disease characterized by repetitive alveolar cell injury, myofibroblast proliferation, and excessive extracellular matrix deposition for which unmet need persists for effective therapeutics. The bioactive eicosanoid, prostaglandin F2α, and its cognate receptor FPr (Ptgfr) are implicated as a TGF-β1-independent signaling hub for IPF. To assess this, we leveraged our published murine PF model (IER-SftpcI73T) expressing a disease-associated missense mutation in the surfactant protein C (Sftpc) gene.

Real-World Treatment Patterns and Clinical Outcomes Among Patients With Advanced Renal Cell Carcinoma.

Background: Nearly 30% of new renal cell carcinoma (RCC) cases are diagnosed at an advanced or metastatic stage. Recent approvals of immunotherapies (IO) have significantly impacted patient care, but real-world outcomes of these treatments have not been widely evaluated.

Methods: Eligible physicians abstracted demographic and clinical data from patient medical records for patients with advanced clear and non-clear cell RCC (aRCC) who initiated treatment between January 1, 2018, and December 31, 2020.

Calcium Sulfate Microparticle Size Modification for Improved Alginate Hydrogel Fabrication and Its Application in 3D Cell Culture.

Calcium ion-crosslinked alginate hydrogels are widely used as a materials system for investigating cell behavior in 3D environments . Suspensions of calcium sulfate particles are often used as the source of Ca to control the rate of gelation. However, the instability of calcium sulfate suspensions can increase chances of reduced homogeneity of the resulting gel and requires researcher's proficiency.

Recurrent Abdominal Aggressive Fibromatosis with Incapacitating Hip Contracture - A Case Report.

Introduction: Aggressive fibromatosis (AF) is a fibroblastic locally aggressive neoplasm arising from the musculoaponeurotic stroma and has no metastatic potential. The high tendency of recurrence despite complete surgical resections makes the management of the condition onerous. It can result in significant morbidity with major functional loss due to the destruction of adjacent vital structures and organs.

Safety Summary of the Selective Cytopheretic Device: A Review of Safety Data Across Multiple Clinical Trials in ICU Patients With Acute Kidney Injury and Multiple Organ Failure.

Objectives: Acute kidney injury (AKI) requiring continuous kidney replacement therapy is a significant complication in ICU patients with mortality rates exceeding 50%. A dysregulated immune response can lead to systemic inflammation caused by hyperactivity of pro-inflammatory neutrophils and monocytes leading to tissue damage. The selective cytopheretic device (SCD) is an investigational medical device in a new class of cell-directed extracorporeal therapies distinct from cytokine adsorbers or filters, as it targets activated leukocytes.

[Peer support for recovery in early intervention for psychosis: Issues surrounding its implementation in Quebec and the French-speaking world].

Objectives To describe the different issues surrounding the integration of peer support workers (PSW) and family peer support workers (FPSW) into early intervention for psychosis services (EIS): their roles, the impacts of these interventions for patients, their families, and treatment teams, as well as the challenges and facilitators of this process. Method This article, co-authored with PSW and FPSW, presents a description and discussion of the experience of implementing peer support and family peer support in EIS in Québec, supported by a perspective of a review of the scientific and grey literature published in French or English in the last twenty years. Results Eight of the 36 scientific articles and two of the 14 grey literature publications selected were specific to early intervention for psychosis; the remainder were on mental health intervention.

Combinations and Temporal Associations Among Precursor Symptoms Before a First Episode of Psychosis.

Background And Hypothesis: Symptoms that precede a first episode of psychosis (FEP) can ideally be targeted by early intervention services with the aim of preventing or delaying psychosis onset. However, these precursor symptoms emerge in combinations and sequences that do not rest fully within traditional diagnostic categories. To advance our understanding of illness trajectories preceding FEP, we aimed to investigate combinations and temporal associations among precursor symptoms.

Tumour Microenvironment as a Potential Immune Therapeutic Target for Tongue Cancer Management.

Immunotherapy is a promising approach in the management of human cancers and has been proven to provide a durable response in many cancers. It is helpful as an adjuvant therapy for cancers and at present is considered as a fourth pillar supporting surgery, chemotherapy and radiotherapy. In the treatment of oral cancer, immunotherapy is approved in late-stage diseases where surgical resection cannot be carried out or fails, leading to recurrences and metastasis.

Trust of patients and families in mental healthcare providers and institutions: a cross-cultural study in Chennai, India, and Montreal, Canada.

Purpose: Cross-cultural psychosis research has typically focused on a limited number of outcomes (generally symptom-related). It is unknown if the purported superior outcomes for psychosis in some low- and middle-income countries extend to fundamental treatment processes like trust. Addressing this gap, we studied two similar first-episode psychosis programs in Montreal, Canada, and Chennai, India.

A systematic study on the kinetics of H-shift reactions in pristine acyl peroxy radicals.

A series of acyl peroxy radical H-shifts were systematically studied using computational approaches. Acyl peroxy radicals were categorized into small- (ethanal-pentanal), medium- (hexanal and heptanal) and large-sized (octanal and nonanal) molecules. The H-shifts spanning from 1,4 to 1,9 were inspected for each studied system.

Intravitreal injection of a rationally designed AAV capsid library in non-human primate identifies variants with enhanced retinal transduction and neutralizing antibody evasion.

Adeno-associated virus (AAV) continues to be the gold standard vector for therapeutic gene delivery and has proven especially useful for treating ocular disease. Intravitreal injection (IVtI) is a promising delivery route because it increases accessibility of gene therapies to larger patient populations. However, data from clinical and non-human primate (NHP) studies utilizing currently available capsids indicate that anatomical barriers to AAV and pre-existing neutralizing antibodies can restrict gene expression to levels that are "sub-therapeutic" in a substantial proportion of patients.
