Nontarget screening of a Siberian ice core reveals changes in the pre-industrial to industrial organic aerosol composition.

Glaciers serve as natural archives for reconstructing past changes of atmospheric aerosol concentration and composition. While most ice-core studies have focused on inorganic species, organic compounds, which can constitute up to 90% of the submicrometer aerosol mass, have been largely overlooked. To our knowledge, this study presents the first nontarget screening record of secondary organic aerosol species preserved in a Belukha ice core (Siberia, Russian Federation), ranging from the pre-industrial to the industrial period (1800-1980 CE).

Phase 2 Randomised Study of Bulevirtide as Monotherapy or Combined With Peg-IFNα-2a as Treatment for Chronic Hepatitis Delta.

Background And Aim: Bulevirtide (BLV) leads to beneficial virologic and biochemical responses when given alone to treat hepatitis delta virus (HDV) infection, which causes the most severe form of chronic viral hepatitis. We evaluated 48 weeks of BLV monotherapy, BLV + tenofovir disoproxil fumarate (TDF) and BLV + pegylated interferon alfa-2a (Peg-IFNα-2a), with 24-week follow-up.

Methods: Ninety patients were enrolled into six arms of 15 each (A-F); 60 patients were included in the main randomisation (arms A-D), and 30 patients (arms E-F) were randomised to the extension phase: (A) Peg-IFNα-2a 180 μg once weekly (QW); (B) BLV 2 mg once daily (QD) + Peg-IFNα-2a 180 μg QW; (C) BLV 5 mg QD + Peg-IFNα-2a 180 μg QW; (D) BLV 2 mg QD; (E) BLV 10 mg QD + Peg-IFNα-2a 180 μg QW and (F) BLV 10 mg (5 mg twice daily) + TDF QD.

Pressure-driven phase transformations on MgCa(CO) huntite carbonate.

Magnesium and calcium carbonate minerals are significant reservoirs of Earth's carbon and understanding their behavior under different conditions is crucial for elucidating the mechanisms of deep carbon storage. Huntite, MgCa(CO), is one of the two stable calcium magnesium carbonate phases, together with dolomite. The distinctive cation coordination environment of Ca atoms compared to calcite-type and dolomite structures makes huntite a comparatively less dense phase.

Cerebral Embolic Protection in Patients Undergoing Left Atrial Appendage Closure.

(1) Background: Cerebral magnetic resonance imaging has reported new cerebral ischemic lesions after left atrial appendage (LAA) closure in about one- third of patients. Stroke occurs predominantly periprocedurally. This study evaluated the characteristics of embolized debris captured by the SENTINEL cerebral embolic protection system in patients undergoing LAA closure; (2) Methods: Sixty filters of 30 consecutive patients undergoing LAA closure with the WATCHMAN FLX device were collected and captured debris was analyzed by histopathology and histomorphometry.

TRIM25: A Global Player of Cell Death Pathways and Promising Target of Tumor-Sensitizing Therapies.

Extract Prescriptions Are Associated with Slower Progression of Dementia Severity-Analysis of Longitudinal Real-World Data.

Background/objectives: Previous research indicates that extract (Gbe) may contribute to slowing down the progression of dementia. This retrospective cohort study analyzed the association between Gbe prescriptions and the progression of dementia severity in a real-world setting.

Methods: This study was conducted using data from patients with an initial diagnosis of mild or moderate dementia between January 2005 and December 2022 from the IQVIA™ Disease Analyzer database.

Creating an Ellipsys percutaneous arteriovenous fistula after a failed ipsilateral WavelinQ fistula: A case report of an endovascular approach for access restoration.

The introduction of devices for endovascular dialysis access creation (WavelinQ and Ellipsys) offers practitioners more options for access management in dialysis patients. Especially in terms of reducing the usage of central venous catheters, a native fistula is desirable as an initial dialysis access. We present a case in which a failed WavelinQ type fistula was reactivated using the Ellipsys procedure on the same arm.

Local adaptation and phenotypic plasticity in two forest understorey herbs in response to forest management intensity.

Local adaptation is a common phenomenon that helps plant populations to adjust to broad-scale environmental heterogeneity. Given the strong effect of forest management on the understorey microenvironment and often long-term effects of forest management actions, it seems likely that understorey herbs may have locally adapted to the practiced management regime and induced environmental variation. We investigated the response of and to forest management using a transplant experiment along a silvicultural management intensity gradient.

Less is more - Retrospective analysis of the two-incision implantation technique for hypoglossal nerve stimulation and comparison of respiratory sensing lead curves against the three-incision technique.

Introduction: Breathing-synchronized hypoglossal-nerve stimulation is a treatment option for suitable patients with severe obstructive-sleep-apnoea. The classical implantation technique requires three incisions: submental to place the stimulating-electrode on terminal branches of the hypoglossal-nerve, sub-clavicular to place the impulse generator, and on the lateral chest-wall to place a breathing-sensor lead. A two-incision-technique has been propagated and widely adopted whereby the respiratory-sensing-lead is placed deeper to the IPG-pocket.

Psychosocial working conditions and violence prevention climate in German emergency departments - a cross-sectional study.

Free Energy, Rates, and Mechanism of Transmembrane Dimerization in Lipid Bilayers from Dynamically Unbiased Molecular Dynamics Simulations.

The assembly of proteins in membranes plays a key role in many crucial cellular pathways. Despite their importance, characterizing transmembrane assembly remains challenging for experiments and simulations. Equilibrium molecular dynamics simulations do not cover the time scales required to sample the typical transmembrane assembly.

Survival Among Patients Treated with Total Mesorectal Excision or Selective Watch-and-Wait After Total Neoadjuvant Therapy: A Pooled Analysis of the CAO/ARO/AIO-12 and OPRA Randomized Phase II Trials.

Background: Prospective data comparing watch-and-wait (WW) to mandatory total mesorectal excision (TME) in patients with locally advanced rectal cancer (LARC) remains limited, as randomized control trials assessing these two treatment approaches are considered impractical. This pooled analysis of the CAO/ARO/AIO-12 and OPRA trials analyzes survival outcomes among LARC patients managed with either a selective WW or mandatory TME strategy following total neoadjuvant therapy (TNT).

Patients And Methods: The CAO/ARO/AIO-12 and OPRA trials were multicenter, phase II trials that randomized patients with stage II/III rectal cancer to receive either induction or consolidation chemotherapy as part of TNT.

Repeatome landscapes and cytogenetics of hortensias provide a framework to trace Hydrangea evolution and domestication.

Background And Aims: Ornamental hortensias are bred from a reservoir of over 200 species in the genus Hydrangea s.l. (Hydrangeaceae), and are valued in gardens, households and landscapes across the globe.

The functional role of oscillatory dynamics in neocortical circuits: A computational perspective.

The dynamics of neuronal systems are characterized by hallmark features such as oscillations and synchrony. However, it has remained unclear whether these characteristics are epiphenomena or are exploited for computation. Due to the challenge of selectively interfering with oscillatory network dynamics in neuronal systems, we simulated recurrent networks of damped harmonic oscillators in which oscillatory activity is enforced in each node, a choice well supported by experimental findings.

Continuous local infiltration analgesia is equal to femoral and sciatic nerve block for total knee arthroplasty.

Background: Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. Pain control is crucial for rapid mobilisation and reduces side effects as well as the length of hospital stay. In this context, a variety of multimodal pain control regimes show good pain relief, including several nerve blocks, iPACK and local infiltration analgesia (LIA).

[Dizziness in old age].

Dizziness is a frequent and often multifactorial symptom in older patients that can significantly impair the quality of life. The causes are diverse and differ from younger patients. Polyneuropathy, orthostatic dysregulation, drug-related causes, positional vertigo and bilateral vestibulopathy are more frequent in old age.
