https://www.selleckchem.com/products/sb239063.html One strategy employed to prolong the ocular half-life of large molecule therapeutics is via covalent attachment to a carrier, resulting in an increase in size thereby slowing their clearance from the eye. Rabbit antigen-binding fragment conjugated to nanolipoprotein (RabFab-NLP) is a novel conjugate intended to prolong ocular half-life through an increase in hydrodynamic radius compared to Fab alone (∼12 vs ∼3 nm). Nanolipoproteins are mimetics of endogenous high-density lipoproteins and consist of lipids and apolipoproteins (ApoE422k), both biologically derived materials. The objective of this study was to evaluate the ocular toxicity and toxicokinetics of RabFab-NLP after a single intravitreal administration in New Zealand White rabbits. Serum toxicokinetic data suggested a significant increase in ocular residence time of RabFab-NLP compared to RabFab alone. Ophthalmic examinations showed that RabFab-NLP caused vitreous and lens opacities as early as day 3 and day 8 postdose, respectively, which persisted for the entire study duration to day 30. The RabFab-NLP-related microscopic findings were present in the lens, vitreous cavity, and/or optic nerve head. Based on the observed ocular toxicity, a single intravitreal dose of 1.3 mg/eye RabFab-NLP was not tolerated and caused vitreous opacity and cataracts in rabbit eyes.Primary Objective To compare child- and parent-report ratings on the Health Behavior Inventory, Revised Child Anxiety and Depression Scale-Short Version (anxiety subscale), Patient Health Questionnaire-9, and Pediatric Quality of Life InventoryTM among children with persistent post-concussive symptoms following a sports- or recreation-related concussion, overall and by child age and gender.Research Design Cross-sectional study examining baseline data from a randomized, comparative effectiveness trial.Methods and Procedures Inter-rater reliability was assessed using two-way random effects model (absol
