An emerging role for endothelial barrier support therapy for congenital disorders of glycosylation.

Congenital disorders of glycosylation (CDGs) are clinically heterogeneous disorders defined by a decreased ability to modify biomolecules with oligosaccharides. Critical disruptions in protein recognition, interaction, binding, and anchoring lead to broad physiological effects. Patients present with endocrinopathy, immunodeficiency, hepatopathy, coagulopathy, and neurodevelopmental impairment.

A Supramolecular Shear-Thinning Anti-Inflammatory Steroid Hydrogel.

Shear-thinning and self-healing steroid-drug-based hydrogels are presented, which exhibit rapid and complete recovery of their mechanical properties within seconds following stress-induced flow. The hydrogels release steroid drug in vivo with no visible residue when release is complete.

Phototriggered Local Anesthesia.

We report a phototriggerable formulation enabling in vivo repeated and on-demand anesthesia with minimal toxicity. Gold nanorods (GNRs) that can convert near-infrared (NIR) light into heat were attached to liposomes (Lip-GNRs), enabling light-triggered phase transition of their lipid bilayers with a consequent release of payload. Lip-GNRs containing the site 1 sodium channel blocker tetrodotoxin and the α2-adrenergic agonist dexmedetomidine (Lip-GNR-TD) were injected subcutaneously in the rat footpad.

Corneal Anesthesia With Site 1 Sodium Channel Blockers and Dexmedetomidine.

Purpose: Amino-amide or amino-ester local anesthetics, which are currently used for topical ocular anesthesia, are short acting and may delay corneal healing with long-term use. In contrast, site 1 sodium channel blockers (S1SCBs) are potent local anesthetics with minimal adverse tissue reaction. In this study, we examined topical local anesthesia with two S1SCBs, tetrodotoxin (TTX) or saxitoxin (STX) individually or in combination with α2-adrenergic receptor agonists (dexmedetomidine or clonidine), and compared them with the amino-ester ocular anesthetic proparacaine.

Kawasaki disease: four case reports of cardiopathy with an institutional and literature review.

Kawasaki disease (KD) is a systemic vasculitis condition with a relatively unknown etiology. First described in 1967 by Tomisaku Kawasaki in Japan, KD has come to be widely diagnosed in every region of the world. The disease has a high prevalence in children ages 6 months to 5 years, particularly in those of Japanese descent.
