Evaluation of Surface Replication of Injection Molded Products Using a Diffraction Method
Abstract: ABSTRACT An evaluation method of surface replication for molded parts, which utilizes optical diffraction phenomena, is proposed. In general, the intensity of the diffracted light increases as the replication ratio becomes large, which leads to the increase in directly transmitted light. As a result, the surface in highly replicated region appears to be darker compared with the other region. An inversely proportional relationship between the 0th-order diffraction efficiency and the …

A Comprehensive Review on Buccal Drug Delivery System
Abstract: Buccal delivery involves the running of the desired drug through the buccal mucosal membrane lining of the oral cavity. The buccal region of the oral cavity is a striking target for administration of the drug of choice because it offers some discrete advantages over all other routes. However, the mucosal lining of the oral cavity drugs which undergo rigorous firstpass metabolism, for those drugs, buccal route are excellent. Buccal drug …

pH-Triggered In-Situ Nasal Gel Systems for Migraine Therapy: A Review
Abstract: Intranasal drug delivery has gained considerable attention as a non-invasive route for delivering drugs to both systemic circulation and the central nervous system, particularly for the treatment of migraine. Traditional nasal formulations such as sprays and drops often show poor therapeutic performance due to rapid mucociliary clearance and limited retention within the nasal cavity. To overcome these challenges, in-situ gel systems have been designed, which transform from a liquid to …
