To investigate the swept-source optical coherence tomography (SS-OCT) and SS-OCT angiography (SS-OCTA) findings in circumscribed choroidal hemangioma (CCH) before after treatment with transpupillary thermotherapy (TTT). The clinical records of 21 eyes having CCH imaged SS-OCT/SS-OCTA between September 2018 December 2022 were evaluated. examination showed dome-shaped appearance (100%), shadowing expansion structures subretinal fluid (66.7%), intraretinal edema/schisis (33.3%), retinal pigment...

Recent reports have demonstrated that refrigerated bevacizumab can be stored for up to 3 weeks at 4 degrees C without loss of efficacy. There been no previous addressing bevacizumab's sterility when and used as multiple doses from a single-use vial.To evaluate the vial.Four groups vials were simulate storage use conditions bevacizumab. Each group contained 11 0.2 mL One sample each was cultured once day 37 10 days; one left 15 days. MacConkey agar, blood thioglycollate broth, Sabouraud...

Purpose. To evaluate the relationship between internal carotid artery (ICA) stenosis and subfoveal choroidal thickness (SFCT) in elderly population. Methods. A total of 42 eyes 21 patients with more than 70% ICA (Group 1) on one side less 2) other were recruited for this study. was diagnosed using both B-mode Doppler ultrasound. The two groups compared terms percentage stenosis, SFCT measurements, intraocular pressure, ocular perfusion refractive error, peak systolic velocity. Eyes examined...

Background/aim: Methotrexate (MTX) is a folic acid antagonist that widely used to treat osteosarcoma, leukemia, breast cancer, and autoimmune inflammatory diseases. The most important concerns with MTX are its poor solubility high toxicity, particularly in liver cells. To enhance minimize we encapsulated niosomes investigated hepatotoxicity mechanisms using genetic biomarkers. Materials methods: Niosomes were successfully prepared modified thin film method, the monodisperse smallsized...

6-Mercaptopurine (6-MCP) is an antiproliferative purine analog used in acute lymphoblastic leukemia, non-Hodgkin lymphoma, and inflammatory bowel disease (Crohn's disease, ulcerative colitis). Although 6-MCP has the great therapeutic potential for cancer immunosuppressant-related diseases, not readily soluble water, presents a high first-pass effect, short half-life (0.5–1.5 h), implies low bioavailability (16%). On contrary, solid lipid nanoparticles (SLNs) are prepared from lipids at room...

Addressing obesity is a critical health concern of the century, necessitating urgent attention. L-carnitine (LC), an essential water-soluble compound, plays pivotal role in lipid breakdown via β-oxidation and facilitates transport long-chain fatty acids across mitochondrial membranes. However, LC’s high hydrophilicity poses challenges to its diffusion through bilayers, resulting limited bioavailability, short half-life, lack storage within body, mandating frequent dosing. In our research, we...
