Dihydrolipoamide dehydrogenase deficiency in five siblings with variable phenotypes, including fulminant fatal liver failure despite good engraftment of transplanted liver.

Dihydrolipoamide dehydrogenase (DLD) deficiency can, in one of its forms, be a rare cause of acute liver failure. Clinical presentation is nonspecific. Biochemical findings can reflect metabolic block, but vary depending on patient and his condition.

Multifunctional Sr,Mg-Doped Mesoporous Bioactive Glass Nanoparticles for Simultaneous Bone Regeneration and Drug Delivery.

Mesoporous bioactive glass nanoparticles (MBGNs) doped with therapeutical ions present multifunctional systems that enable a synergistic outcome through the dual delivery of drugs and ions. The aim of this study was to evaluate influence of co-doping with strontium and magnesium ions (SrMg-MBGNs) on the properties of MBGNs. A modified microemulsion-assisted sol-gel synthesis was used to obtain particles, and their physicochemical properties, bioactivity, and drug-loading/release ability were evaluated.

Enhanced personal protective equipment and dental students' experience and quality of a restorative procedure in a simulated clinical setting.

Objectives: To evaluate the effects of enhanced personal protective equipment (Enhanced_PPE) on student-operator's experience and restorative procedure.

Methods: Student-operators (N = 29 Year 3 dental students) performed Class II composite restorations (SimpliShade, Kerr) in typodont upper molars (OneDental) equipped with N95 respirators, full-face shields, disposable headwear and gowns (Enhanced_PPE) or surgical masks, protective glasses/goggles and non-disposable gowns (Standard_PPE) 2 weeks later. Cavity dimensions were measured on cone beam computed tomography images.

A step towards tuning the jute fiber structure and properties by employing sodium periodate oxidation and coating with alginate.

This paper outlines a novel simple protocol for tuning the structure and properties of jute using sodium periodate (NaIO) oxidation and coating with alginate. When compared to the raw jute, fabrics oxidized with a 0.2 or 0.

Hydroxyapatite-based dental inserts: Microstructure, mechanical properties, bonding efficiency and fracture resistance of molars with occlusal restorations.

This study aimed to (1) comparatively analyze properties of Sr- and Mg-substituted hydroxyapatite (HAP)-based dental inserts; (2) evaluate insert bonding to restorative materials, and (3) evaluate the effect of doped HAP inserts on fracture resistance (FR) of human molars with large occlusal restorations. By ion-doping with Sr or Mg, 3 insert types were obtained and characterized using XRD, SEM, Vickers hardness and fracture toughness. Shear bond strength (SBS) was determined between acid etched or unetched inserts and following materials: Maxcem cement (Kerr); Filtek Z250 (3M) bonded with Single Bond Universal (SBU; 3M) or Clearfil Universal (Cf; Kuraray).
