The nitrogen-nitrogen bond is a core feature of diverse functional groups like hydrazines, nitrosamines, diazos, and pyrazoles. Such functional groups are found in >300 known natural products. Such N-N bond-containing functional groups are also found in significant percentage of clinical drugs. Therefore, there is wide interest in synthetic and enzymatic methods to form nitrogen-nitrogen bonds. In this review, we summarize synthetic and biosynthetic approaches to diverse nitrogen-nitrogen-bond-containing functional groups, with a focus on biosynthetic pathways and enzymes.

Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Background: Synthesis of organic@inorganic hNFs is achieved by the coordination of organic compounds containing amine, amide, and diol groups with bivalent metals. The use of bio-extracts containing these functional groups instead of expensive organic inputs such as DNA, enzymes, and protein creates advantages in terms of cost and applicability. In this study, the application potentials (antioxidant, antibacterial, anticancer, guaiacol, anionic, and cationic dye degradation) of hybrid (organic@inorganic) nanoflowers (hNFs) synthesized with Cu and snakeskin (SSS) were proposed.

Objective: To investigate the application value of arthroscopic channel modification in meniscal injury repair.
Methods: We retrospectively analyzed the data of 100 patients with meniscus injuries treated with knee arthroscopy from December 2022 to December 2023 and divided them into a control group and a modified group according to the application of "arthroscopic access modification technology". We compared the operation time, postoperative hospitalization time, VAS score, Lysholm knee function score, postoperative complications, and postoperative images of the patients in these two groups.

Background: The evidence indicates that functional training is beneficial for athletes' physical and technical performance. However, a systematic review of the effects of functional training on athletes' physical and technical performance is lacking. Therefore, this study uses a literature synthesis approach to evaluate the impact of functional training on the physical and technical performance of the athletic population and to extend and deepen the existing body of knowledge.

Background: Given the increasing recognition of the value of greater integration of physical and mental health services for children and young people, we aimed to evaluate preferences among parents for the characteristics associated with integrated health service provision for two conditions (eating disorders, functional symptom disorders).
Methods: Two discrete choice experiments (DCEs) were conducted, using electronic surveys. Participants were adult parents of children and young people.
