Article Abstract
A tunable narrow linewidth UV laser near 308 nm is necessary for highly sensitive hydroxyl (OH) radical measurement. We demonstrated a high-power fiber-based single frequency tunable pulsed UV laser at 308 nm. The UV output is generated from the sum frequency of a 515 nm fiber laser and a 768 nm fiber laser, which are harmonic generations from our proprietary high-peak-power silicate glass Yb- and Er-doped fiber amplifiers. A 3.50 W single frequency UV laser with 100.8 kHz pulse repetition rate, 3.6 ns pulse width, 34.7 µJ pulse energy, and 9.6 kW peak power has been achieved, which represents the first demonstration, to the best of our knowledge, of a high-power fiber-based 308 nm UV laser. With temperature control of the single frequency distributed feedback seed laser, the UV output is tunable for up to 792 GHz at 308 nm.

Background: We aimed to document childhood onset mevalonate kinase deficiency (MKD) and to explore treatment responses and diagnostic challenges in regions endemic to familial Mediterranean fever (FMF).
Methods: This retrospective study included patients under 18 years of age, diagnosed with MKD and followed for at least six months at the pediatric rheumatology department of Istanbul University - Cerrahpaşa Medical Faculty between 2016 and 2024.
Results: Of 33 patients, 51.
Monocyte Anisocytosis Can Discriminate Between Sepsis and Sterile Inflammation, but not Mortality, in Critically Ill Surgical/Trauma Patients: A Secondary Prospective Analysis.

Objectives Background: Monocyte anisocytosis (monocyte distribution width [MDW]) has been previously validated to predict sepsis and outcome in patients presenting in the emergency department and mixed-population ICUs. Determining sepsis in a critically ill surgical/trauma population is often difficult due to concomitant inflammation and stress. We examined whether MDW could identify sepsis among patients admitted to a surgical/trauma ICU and predict clinical outcome.

Capturing the dynamic changes in patients' internal states as they approach death due to fatal diseases remains a major challenge in understanding individual pathologies and improving end-of-life care. However, existing methods primarily focus on specific test values or organ dysfunction markers, failing to provide a comprehensive view of the evolving internal state preceding death. To address this, we analyzed electronic health record (EHR) data from a single institution, including 8,976 cancer patients and 77 laboratory parameters, by constructing continuous mortality prediction models based on gradient-boosting decision trees and leveraging them for temporal analyses.

Background And Aims: Sickle cell disease (SCD) patients are at a higher risk of pneumococcal invasive diseases. Vaccination is the central strategy for protecting these children, along with penicillin prophylaxis. However, it is unclear how often these children should be revaccinated with pneumococcal vaccines.

Biomolecular dynamics in the microsecond-to-millisecond (µs-ms) timescale are linked to various biological functions, such as enzyme catalysis, allosteric regulation, and ligand recognition. In solution state NMR, Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion experiments are commonly used to probe µs-ms timescale motions, providing detailed kinetic, thermodynamic, and mechanistic information at the atomic level. For investigating conformational dynamics in high-molecular-weight biomolecules, methyl groups serve as ideal probes due to their favorable relaxation properties, and C CPMG relaxation dispersion is widely employed for characterizing dynamics in selectively CH-labeled samples.
