A 42-year-old man presented with right-sided epiphora, a fleshy lesion emanating from the right inferior punctum and a painless mass below the medial canthal tendon. Biopsy of the lacrimal sac mass disclosed papillary squamous cell carcinoma in situ. The patient underwent wide local excision with clear surgical margins and remained disease free until 28 months later when he returned with hemorrhagic epiphora of the OS and fullness overlying the left lacrimal sac. Biopsy confirmed papillary squamous cell carcinoma in situ. He underwent similar excision and has remained disease free for 6 months. To the best of the authors' knowledge, this is the first report of bilateral squamous cell carcinoma of the lacrimal sac.

January 2025
Department of Stomatologic Sciences, School of Dentistry, Federal University of Goiás, Goiânia, Goiás, Brazil.
Objective: To investigate the clinical manifestations of head and neck cancer in patients with Plummer-Vinson syndrome (PVS) and to assess related oral comorbidities.
Materials And Methods: Case reports covering head and neck cancer manifestations in patients diagnosed with PVS were included Studies were identified through seven main electronic databases (PubMed/MEDLINE, EMBASE, Scopus, Web of Science, CINAHL, LILACS, and LIVIVO), and a search for gray literature was performed using ProQuest Dissertations and Theses and Google Scholar. Independent reviewers applied predefined eligibility criteria in a two-phase selection process.
Copper-luteolin nanocomplexes for Mediating multifaceted regulation of oxidative stress, intestinal barrier, and gut microbiota in inflammatory bowel disease.

Oxidative stress, dysbiosis, and immune dysregulation have been confirmed to play pivotal roles in the complex pathogenesis of inflammatory bowel disease (IBD). Herein, we design copper ion-luteolin nanocomplexes (CuL NCs) through a metal-polyphenol coordination strategy, which plays a multifaceted role in the amelioration of IBD. The fabricated CuL NCs function as therapeutic agents with exceptional antioxidant and anti-inflammatory capabilities because of their great stability and capacity to scavenge reactive oxygen species (ROS).

Unlabelled: Cervical cancer (CC) represents one of the important cancers affecting global female population worldwide. We sought to elucidate the roles and mechanisms of KIAA1429 in the malignant properties of CC cells and the epithelial-mesenchymal transition (EMT) process. KIAA1429 was predicted to be abnormally expressed in CC and correlate with shortened survival of CC patients by GEPIA2 and GSCA databases.

Background: Acacetin (AC) is a flavonoid compound with antiperoxidant, anti-inflammatory, and antiplasmodial activity. However, the solubility of AC is poor and nano acacetin (Nano AC) was synthesized. The intestinal mucosal barrier is impaired in sepsis rats, and the protective effects and mechanism of AC and Nano AC on the intestinal mucosal barrier are unclear.
