Marey broke movement down into a series of stills. We still use this approach but technical advances, especially in computing, allow us to record cinematics, kinetics and electrical muscular activity simultaneously. We now have a better understanding of gait disorders in children with motor disabilities, challenging previous surgical indications and leading to the concept of single-procedure "multisite" surgery with spectacular improvements in outcome.

Despite being one of the most frequently used chemotherapy agents, cisplatin exhibits substantial hepatorenal injury by triggering oxidative stress, inflammation, and apoptosis pathways. The current investigation studied the possible protective effects of calcitriol on cisplatin-induced hepatorenal toxicity. Mice were divided randomly as follows: control group, calcitriol group (received calcitriol 5 µg/kg, p.

In September 2020, the Western United States experienced anomalously severe wildfires that resulted in carbon monoxide (CO) emissions almost three times the 2001-2019 average. In this study, we investigate the influence of wildfires on atmospheric carbon monoxide (CO) variability through a comparative analysis of observations from the Measurements of Pollution in the Troposphere (MOPITT), the Infrared Atmospheric Sounding Interferometer (IASI), and the Tropospheric Monitoring Instrument (TROPOMI). Our focus is on the North American domain, aiming to understand the differences among these products.

Ruptures of the quadriceps tendon (QT) are rare but serious injuries accounting for less than 2% of all tendon injuries around the knee. These injuries, often occurring in individuals over 40, are leading to a loss of active extension and a significant impact on knee function. While the treatment of acute QT ruptures through various reinsertion techniques has shown excellent outcomes, managing chronic injuries and failed primary repairs remains challenging due to tendon retraction and difficulties in repositioning the tendon stump.
