Complications in anterior cruciate ligament reconstruction.

Anterior cruciate ligament reconstruction (ACLR), despite its effectiveness in restoring knee stability and function, can have associated morbidity. The most frequent complications are technical errors, which have been described during graft harvesting, tunnel placement or graft fixation. The most serious complications are neurovascular injuries, arthrofibrosis and infections.

Pathovar Infection Reveals Different Defense Mechanisms in Two Sweet Cherry Cultivars.

pv. is the main causal agent of bacterial canker in sweet cherry in Chile, causing significant economic losses. Cultivars exhibit diverse susceptibility in the field and the molecular mechanisms underlying the differential responses remain unclear.

Poincaré plot analysis of ECG uncovers beneficial effects of omaveloxolone in a mouse model of Friedreich's ataxia.

Background: Friedreich's ataxia (FA) is a rare inherited neuromuscular disorder, where most patients die from lethal cardiomyopathy and arrhythmias. Mechanisms leading to arrhythmic events in FA patients are poorly understood.

Objective: This study aims to examine cardiac electrical signal propagation in mouse model of FA with severe cardiomyopathy and evaluate effects of omaveloxolone (OMAV), the first FDA-approved therapy.

Safety and efficacy of mesenchymal stromal cells mitochondria transplantation as a cell-free therapy for osteoarthritis.

Objective: The inflammatory responses from synovial fibroblasts and macrophages and the mitochondrial dysfunction in chondrocytes lead to oxidative stress, disrupt extracellular matrix (ECM) homeostasis, and accelerate the deterioration process of articular cartilage in osteoarthritis (OA). In recent years, it has been proposed that mesenchymal stromal cells (MSC) transfer their functional mitochondria to damaged cells in response to cellular stress, becoming one of the mechanisms underpinning their therapeutic effects. Therefore, we hypothesize that a novel cell-free treatment for OA could involve direct mitochondria transplantation, restoring both cellular and mitochondrial homeostasis.

Photosynthetic Activity Measured In Situ in Microalgae Cultures Grown in Pilot-Scale Raceway Ponds.

The microalga sp. (Chlorophyceae) was cultured in a raceway pond (RWP) placed in a greenhouse. The objective of this case study was to monitor the photosynthesis performance and selected physicochemical variables (irradiance, temperature, dissolved oxygen concentration) of microalgae cultures in situ at various depths of RWP.
