We experimentally demonstrated a diode-pumped 587 fs ultrafast laser by using an a-cut Nd:CaYAlO crystal. Pumped by an 808 nm fiber-coupled laser diode, a stable continuous-wave mode-locked ultrafast laser was achieved with a semiconductor saturable absorber. The ultrafast pulses had a repetition rate of 75 MHz at the center wavelength of 1080.8 nm. A maximum average output power of the mode-locked laser reached 375 mW delivering a slope efficiency of 9%.

Background: Transcatheter arterial chemoembolization (TACE) is a well-known standard treatment for hepatocellular carcinoma (HCC); however, the effectiveness of this treatment can vary among patients.
Objectives: This study aimed to develop a novel imaging-based prediction score (Sultan's score) to predict complete response after treatment.
Methods: From January 2015 to 2021, 41 patients with solitary HCC, admitted at King Saud University Medical City, Riyadh, Saudi Arabia, were treated with drug-eluting TACE (DEBTACE).

Introduction: Observational studies have found that higher iron levels are associated with an increased risk of diabetes mellitus. Given the limitations of causal inferences from observational studies and the expensive and time-consuming nature of randomized controlled trials, Mendelian randomization analysis presents a reasonable alternative to study causal relationships. Previous MR analyses studying iron levels and diabetes have used indirect markers of iron levels, such as serum ferritin, and found conflicting results.
