Purpose: To evaluate the effectiveness of injectable implants made of hyaluronic acid gel (HAG) in ophthalmoplastics.
Material And Methods: The study included 57 patients (37 patients with lagophthalmos related to acute or chronic facial nerve palsy, endocrine ophthalmopathy; 20 patients with enophthalmos, anophthalmic syndrome). Depending on filler particle size, the patients received either intrapalpebral or intraorbital HAG injection. The biometric measures of palpebral fissure, the position of the eye/implant, and the condition of the cornea were evaluated during the follow-up period (12 months for eyelid and 18 for orbital injection).
Results: In the course of the follow-up, all patients showed reliable reduction of lagophthalmos; additionally, improvement of the condition of the cornea was observed in patients after intrapalpebral injection; patients after intraorbital injection exhibited reduction in enophthalmos, upper orbital palpebral fold retraction and upper eyelid excursion. No serious complications have occurred after the injection.
Conclusion: As minimally invasive method of treating various pathologies of the orbit and eyelids, HAG fillers showed good clinical effectiveness and safety.

Background: Nemonoxacin is a new quinolone with an antibacterial efficacy against methicillin-resistant Staphylococcus aureus (MRSA). Certain sequence types (STs) have been emerging in Taiwan, including fluoroquinolone-resistant ST8/USA300. It's an urgent need to determine nemonoxacin susceptibility against ST8/USA300 and other emerging lineages, if any.

In the quest for an ideal wound healing material, human amniotic membrane (AM), tilapia skin collagen (TSC), and Centella asiatica (CA) have been studied separately for their healing potential. In this study, we formulated AM, TSC, and CA gel and studied their competency and wound healing efficacy in vivo. Gel was formulated using AM, TSC, CA, Carbopol 934, acrylic acid, glycerine, and triethanolamine and physicochemical properties e.

Purpose: To study the roles of tubulin acetylation and cyclic mechanical stretch (CMS) in trabecular meshwork (TM) cells and their impact on outflow pathway physiology and pathology.
Methods: Primary TM cell cultures were subjected to CMS (8% elongation, 24 hours), and acetylated α-tubulin at lysine 40 (Ac-TUBA4) was assessed by western blotting and immunofluorescence. Enzymes regulating tubulin acetylation were identified via siRNA-mediated knockdowns of ATAT1, HDAC6, and SIRT2.
