[Assessment of the severity of oxidative stress and inflamaging in elderly patients with copd who have suffered an ischemic stroke.].

The study assessed the severity of inflamaging, lipid peroxidation, as well as the state of antioxidant protection in elderly patients with chronic obstructive pulmonary disease (COPD), depending on the ischemic stroke (IS). A prospective cohort study included 138 elderly patients (mean age 68±4 years). Of these, the 1st (control) group consisted of 30 people who did not have established COPD and cardiovascular diseases comparable in gender and age to the patients of the main group.

Treatment of Urolithiasis with Thulium Fiber Laser in Fragmentation Mode Using Optimized Pulse Sequences.

The super-pulsed thulium fiber laser (SP TFL) is a new alternative to high-power holmium laser for intracorporeal lithotripsy. The SP TFL has shown advantages in dusting regimes, but benefits in fragmentation regimes are less understood. The second-generation SP TFL introduces an advanced fragmentation pulse (AFP) sequence to maximize SP TFL's efficiency in fragmentation.

Red-to-Blue Triplet-Triplet Annihilation Upconversion for Calcium Sensing.

Triplet-triplet annihilation upconversion is a bimolecular process converting low-energy photons into high-energy photons. Here, we report a calcium-sensing system working via triplet-triplet annihilation (TTA) upconverted emission. The probe itself was obtained by covalent conjugation of a blue emitter, perylene, with a calcium-chelating moiety, and it was sensitized by the red-light-absorbing photosensitizer palladium(II) tetraphenyltetrabenzoporphyrin (PdTPTBP).
