Objective: To investigate the structural alterations, neovascularity, and elasticity of tendons and the relationship between elasticity and the Patient Rated Tennis Elbow Evaluation score after undergoing US-guided fenestration or surgery in patients with chronic lateral elbow tendinopathy.
Methods: Participants from the per-protocol population of a randomized trial conducted between October 2016 and June 2020 were included. The surgery and fenestration groups included 24 (mean age, 50 ± 7 years [standard deviation], 10 men) and 29 (47 ± 8 years, 18 men) participants, respectively.
The automation of pollen identification has seen vast improvements in the past years, with Convolutional Neural Networks coming out as the preferred tool to train models. Still, only a small portion of works published on the matter address the identification of fossil pollen. Fossil pollen is commonly extracted from organic sediment cores and are used by paleoecologists to reconstruct past environments, flora, vegetation, and their evolution through time.

- Polar microalgae, like the Arctic diatom Chaetoceros neogracilis, face significant challenges due to cold temperatures and fluctuating light conditions, which impact their growth and enzyme efficiency.
- This study found that C. neogracilis can adapt to different light levels and temperatures, displaying high levels of Rubisco, low re-oxidation of fixed carbon, and alternative electron transport pathways to sustain energy without relying heavily on organic carbon.
- These adaptations contribute to efficient growth in extreme environments, indicating that polar microalgae have unique mechanisms that differ from temperate species in how they manage photosynthesis and carbon fixation.
Objective: Evaluate the efficacy of ultrasound-guided dry needling and open-release surgery in reducing pain and improving function in workers with lateral epicondylosis refractory to at least 6 months of nonsurgical management.
Methods: We randomly assigned participants in a 1:1 ratio to receive dry needling or surgery. The primary outcome was the Patient Rated Tennis Elbow Evaluation (PRTEE) score at 6 months.
