Synergistic Anion and Solvent-Derived Interphases Enable Lithium-Ion Batteries under Extreme Conditions.

Lithium-ion batteries (LIBs) face increasingly stringent demands as their application expands into new areas, including extreme temperatures and fast charging. To meet these demands, the electrolyte should enable fast lithium-ion transport and form stable interphases on electrodes simultaneously. In practice, however, improving one aspect often compromises another.

Clinical Outcomes After Innovative Multipoint Impedance-Controlled Radiofrequency Ablation of the Posterior Nasal Nerve for Treatment of Chronic Rhinitis.

Chronic rhinitis substantially impacts a person's quality of life. We evaluated a novel, multipoint, impedance-controlled, radiofrequency ablation device for the treatment of chronic rhinitis. This was a prospective, multicenter, single-arm clinical study of posterior nasal nerve ablation in adults with chronic rhinitis.

An ensemble machine learning model generates a focused screening library for the identification of CDK8 inhibitors.

The identification of an effective inhibitor is an important starting step in drug development. Unfortunately, many issues such as the characterization of protein binding sites, the screening library, materials for assays, etc., make drug screening a difficult proposition.

Label-free metabolic optical biomarkers track stem cell fate transition in real time.

Tracking stem cell fate transition is crucial for understanding their development and optimizing biomanufacturing. Destructive single-cell methods provide a pseudotemporal landscape of stem cell differentiation but cannot monitor stem cell fate in real time. We established a metabolic optical metric using label-free fluorescence lifetime imaging microscopy (FLIM), feature extraction and machine learning-assisted analysis, for real-time cell fate tracking.

Incorporating Microdebrider Use in a Community-Based Thyroidectomy Practice.

Substernal goiters often require surgery, yet their location presents challenges. Most can be removed via transcervical approach, but extent and relationship to mediastinal structures can merit consideration of sternotomy and assistance of colleagues. Despite widespread use in sinus surgery and previous literature reports, microdebrider use to facilitate transcervical removal of substernal goiters has not been broadly adopted.

Radial arterial waves for chemotherapy- and radiotherapy-related myocardial damage identification in patients with breast cancer.

Introduction: Chemotherapy and radiation therapy for breast cancer cause side effects, such as cardiovascular changes, which can be monitored with echocardiography. However, more convenient methods are always encouraged. Radial arterial waves that are used to detect cardiovascular changes can be used to assist in confirming cardiovascular changes.

Acoustic resonance therapy is safe and effective for the treatment of nasal congestion in rhinitis: A randomized sham-controlled trial.

Background: Acoustic resonance therapy (ART) is a novel vibrational treatment that delivers patient-specific resonant frequency acoustic energy to the sinonasal cavities. In a pilot study, ART was effective for the acute treatment of nasal congestion. We conducted a sham-controlled randomized trial to validate the efficacy of ART when administered daily for 2 weeks.

Triple Threat: HDV, HBV, HIV Coinfection.

Hepatitis delta virus (HDV) only infects patients with hepatitis B virus (HBV) due to its reliance on HBV surface proteins to form its envelope. With shared routes of transmission, HDV coinfection is estimated to occur in 15% of patients with HIV and HBV. However, HDV is often underdiagnosed and may be missed particularly in people living with HIV (PLWH) who are already on antiretroviral therapy with anti-HBV activity and coincidental HBV suppression.
