The patient was a 36-year-old woman with a chief complaint of pain of the urethral meatus. A cyst existed just below the urethral meatus. The paraurethral cyst was removed completely. Histologically, the cyst was lined by stratified squamous epithelium. According to the criteria proposed by Das, paraurethral cysts are classified into 4 groups: epithelial inclusion cysts, Müllarian cysts, Gärtner duct cysts, Skene duct cysts. In this case, the cyst seemed to be an epithelial inclusion cyst. In the Japanese literature, paraurethral cysts have been incompletely classified from an etiological perspective. Differential diagnoses based on the histological findings of the cysts may be important to determine the etiology.

Biological systems are complex, encompassing intertwined spatial, molecular and functional features. However, methodological constraints limit the completeness of information that can be extracted. Here, we report the development of INSIHGT, a non-destructive, accessible three-dimensional (3D) spatial biology method utilizing superchaotropes and host-guest chemistry to achieve homogeneous, deep penetration of macromolecular probes up to centimeter scales, providing reliable semi-quantitative signals throughout the tissue volume.

Diarrhea associated with enteric infections, gut inflammation, and genetic defects poses a major health burden and results in significant morbidity and mortality. Impaired fluid and electrolyte absorption and/or secretion in the intestine are the hallmark of diarrhea. Electroneutral NaCl absorption in the mammalian GI tract involves the coupling of Na/H and Cl/HCO exchangers.

Mycobacterium avium complex bacteria cause chronic pulmonary disease (MAC-PD) in susceptible patients [1]. The recommended treatment regimen (rifampicin, ethambutol and azithromycin) achieves 65% cure rates but with considerable toxicity and drug-drug interactions [2,3]. Minocycline proved active in monotherapy experiments using the hollow-fibre model [4].

Department of Pharmaceutical Technology and Biopharmaceutics, Faculty of Pharmacy, Medical University of Sofia, 2 Dunav Str., 1000 Sofia, Bulgaria.
The study investigates the development and characterization of dual-loaded niosomes incorporated into ion-sensitive in situ gel as a potential drug delivery platform for ophthalmic application. Cannabidiol (CBD) and epigallocatechin-3-gallate (EGCG) simultaneously loaded niosomes were prepared via the thin film hydration (TFH) method followed by pulsatile sonication and were subjected to comprehensive physicochemical evaluation. The optimal composition was included in a gellan gum-based in situ gel, and the antimicrobial activity, in vitro toxicity in a suitable corneal epithelial model (HaCaT cell line), and antioxidant potential of the hybrid system were further assessed.
