Sapphire is an attractive material in photonic, optoelectronic, and transparent ceramic applications that stand to benefit from surface functionalization effects stemming from micro/nanostructures. Here we investigate the use of ultrafast lasers for fabricating nanostructures in sapphire by exploring the relationship between irradiation parameters, morphology change, and selective etching. In this approach an ultrafast laser pulse is focused on the sapphire substrate to change the crystalline morphology to amorphous or polycrystalline, which is characterized by examining different vibrational modes using Raman spectroscopy.

Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.
Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia, with ventricular rate control being a critical therapeutic target. However, the optimal range for ventricular rate control remains unclear. Additionally, the relationship between different levels of ventricular rate control and cardiac remodeling in patients with atrial fibrillation remains unclear.

Background Cough in common cold is often associated with rhinorrhoea and nasal congestion, requiring treatment with a cough suppressant, decongestant, and antihistamine. Bilastine is a non-sedating antihistamine, a preferred option over sedating antihistamines. A combination of bilastine, dextromethorphan, and phenylephrine is expected to provide non-sedating treatment for cough associated with a common cold or allergy.

Background: During the COVID-19 pandemic, managing respiratory failure in critically ill patients has presented significant challenges. A high-flow nasal cannula (HFNC) has been established as an effective respiratory support modality, offering heated, humidified oxygen at high flow rates. However, concerns persist regarding the potential for aerosol dispersion and the risk of viral transmission, particularly in COVID-19.
