Regulatory authorities in various countries have successively issued notices and guidance to pharmaceutical manufacturers and distributors to evaluate the risk of contamination of nitrosamines in pharmaceutical products and to take appropriate measures. Analysis of nitrosamines in pharmaceutical products is not easy due to the large number of foreign substances, and the risk of contamination is determined by first conducting a desk investigation of the manufacturing process of the APIs or pharmaceutical products. However, a desk investigation may miss the risk since this method is not based on actual measurements.

Intracranial solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) are rare, aggressive tumors typically found along the dural sinuses. Despite their aggressive nature, complete surgical resection remains the most significant factor in reducing recurrence and improving survival. Here, we present the case of a 32-year-old male patient who presented with a new-onset headache and vertigo.

Estrogen receptor-positive (ER+) and estrogen receptor-negative (ER-) breast cancers have different genomic architecture and show large-scale gene expression differences consistent with different cellular origins, which is reflected in the luminal (i.e., ER+) versus basal-like (i.

Persistent trigeminal artery (PTA) is the most common residual manifestation of persistent carotid-vertebrobasilar anastomosis, with the medial-type (intrasellar or sphenoidal) PTA being exceptionally rare. Aneurysms originating from the PTA trunk are not common. We present a unique case of an aneurysm located at the trunk of the medial-type PTA in a patient presenting with trigeminal neuralgia who successfully received endovascular treatment.

Microalgae-based wastewater treatment could realize simultaneous nutrients recovery and CO sequestration. However, impacts of environmental microplastics (MPs) and antibiotic co-exposure on microalgal growth, nutrients removal, intracellular nitric oxide (NO) accumulation and subsequent nitrous oxide (NO) emission are unclarified, which could greatly offset the CO sequestration benefit. To reveal the potential impacts of environmental concentrations of MPs and antibiotic co-exposure on microalgal greenhouse gas mitigation, this study investigated the effects of representative MPs (PE, PVC, PA), antibiotic sulfamethoxazole (SMX), and nitrite (NO-N) in various combinations on attached Chlorella sorokiniana growth, nutrients removal, anti-oxidative responses, and NO emission originated from intracellular NO build-up.
