Objectives: This 1-year long-term extension (LTE) study (NCT04451772) followed the 48-week phase 2 SLEek study (NCT03978520) that evaluated upadacitinib (a Janus kinase inhibitor) alone or combined with elsubrutinib (a Bruton's tyrosine kinase inhibitor) in adults with moderately to severely active systemic lupus erythematosus (SLE). The objective was to evaluate the efficacy and safety of an additional 56 weeks of treatment.

Methods: Patients randomised to upadacitinib 30 mg one time per day (QD) or upadacitinib 30 mg/elsubrutinib 60 mg QD (upadacitinib/elsubrutinib) in the SLEek study continued their assigned treatment during the LTE.

We have developed a readily feasible Mannich-type reaction of alkylazaarenes with aminals, demonstrating excellent functional group tolerance and scalability. Mechanistic studies reveal that the reactivity and selectivity are governed by the electronic effects in conjunction with the stability and steric hindrance of the enamine intermediates. The resulting aminomethylated products hold promising potential for applications in organic synthesis, medicinal chemistry, and ligand design.

The transverse spin angular momentum (SAM) observed in evanescent waves, interference fields, and tightly focused vector beams is directly related to both academic research and technical applications. In this work, we theoretically propose and experimentally generate the generalized hybrid polarized vector beam (GHPVB), which superimposes the orthogonal electric field vector components of the two cylindrical vector beams with topological charges and , with an initial phase difference of between them. First, we investigate the longitudinal SAM separation in weakly focused GHPVBs.

Asthenozoospermia and teratozoospermia are common causes of male infertility. Despite their prevalence, the underlying metabolic mechanisms remain poorly understood. In this study, we conducted targeted metabolomic profiling of sperm samples from 131 Chinese reproductive-age men (48 normozoospermic controls, 40 asthenozoospermic patients, and 43 teratozoospermic patients) to identify distinct metabolic signatures associated with these conditions.

We summarized the clinical manifestations, auxiliary examinations, treatment, and prognostic characteristics of a patient with neurexin-3a IgG-mediated autoimmune encephalitis. On March 2, 2024, a 43-year-old male patient was admitted to the Second Hospital of Shandong University and had prodromal symptoms of infection before the onset of encephalitis. The main manifestations were episodic loss of consciousness, eyes turned upward to the right, clenched teeth, bleeding from tongue bite, and limb twitching.

Despite wide variation, each cell type has an optimal size. Maintaining optimal size is essential for cellular fitness and function but the biological basis for this remains elusive. Here, we performed fitness analysis involving genome-wide CRISPR-Cas9 knockout data from tens of human cell lines and identified that cell size influences the essentiality of genes related to mitochondria and membrane repair.

Hypoxia, excessive reactive oxygen species (ROS), and an impaired inflammatory microenvironment are key barriers to diabetic wound healing, collectively hindering cell migration, proliferation, and neovascularization, ultimately leading to failure in the healing process. Therefore, developing an effective therapeutic strategy capable of simultaneously addressing these challenges remains a critical clinical need. In this study, we developed CeS-Gel, an advanced hydrogel dressing integrating live microalgae and CeO₂ nanoparticles within a dual-crosslinked silk hydrogel network.

The accumulation of amyloid β (Aβ) protein, derived from the amyloid precursor protein (APP), plays a pivotal role in the pathogenesis of Alzheimer's disease (AD) by inducing neuronal cell injury. This study investigated the specific functions of ubiquitin-specific protease 1-associated factor 1 (UAF1) in mediating the neurotoxic effects triggered on Aβ. To model AD-related neuronal injury in vitro and in vitro, SH-SY5Y cells exposed to Aβ and APPswe/PS1dE9 (APP/PS1) transgenic mice were utilized.
