AI Article Synopsis
Article Abstract
An optical nose chip is developed using surface functionalized mesoporous colloidal photonic crystal beads as elements. The prepared optical nose chip displays excellent discrimination among a very wide range of compounds, not only the simplex organic vapors from the different or same chemical family, but also the complex expiratory air from different people.

Pyrimidinergic P2Y1-Like Nucleotide Receptors Are Functional in Rat Conjunctival Goblet Cells.
Invest Ophthalmol Vis Sci
January 2025
Schepens Eye Research Institute, Massachusetts Eye and Ear Infirmary, Department of Ophthalmology, Harvard Medical School, Boston, Massachusetts, United States.
Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.
Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.
Undifferentiated pleomorphic sarcoma in the maxillary sinus: a case report.
J Med Case Rep
January 2025
Department of Oral and Maxillofacial Pathology, School of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
Background: Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, is a type of malignant mesenchymal tumor (sarcoma) of soft tissue and sometimes bone. It is uncommon in the oral cavity and very sporadic in the maxillary sinus. Microscopic diagnosis of this malignancy in the maxillary sinus can be very challenging, because there is a range of features that may overlap with other benign and malignant tumors.

Acute acquired comitant esotropia (AACE) is a concomitant strabismus characterized by sudden onset, mostly associated with diplopia. The prevalence of AACE has significantly increased, and various management approaches have been recommended in recent years. This study by the Council of Asia-Pacific Strabismus and Pediatric Ophthalmology Society aimed to provide an overview of the clinical features, etiology and the nonsurgical and surgical treatment recommendations for the condition to equip strabismus specialists with the most updated knowledge.

CMPK2 promotes NLRP3 inflammasome activation via mtDNA-STING pathway in house dust mite-induced allergic rhinitis.
Clin Transl Med
January 2025
Allergy Center, Department of Otolaryngology, Affiliated Eye and ENT Hospital, Fudan University, Shanghai, China.
Background: House dust mite (HDM) is the leading allergen for allergic rhinitis (AR). Although allergic sensitisation by inhaled allergens renders susceptible individuals prone to developing AR, the molecular mechanisms driving this process remain incompletely elucidated.
Objective: This study aimed to elucidate the molecular mechanisms underlying HDM-induced AR.
