Background: The quantitative outcome of secondary reanimation after a failed primary reconstruction attempt for facial paralysis is rarely reported in the literature. This study aimed to investigate the feasibility of secondary reanimation with gracilis free muscle transfer (GFMT) and whether this outcome is influenced by the primary reconstruction.
Methods: Twelve patients with previously failed static procedures (static group, n = 6), temporal muscle transfer (temporal transfer group, n = 2), and GFMT (GFMT group, n = 4) were all secondarily reanimated with GFMT. The clinical outcome was graded with the eFACE metric. The objective oral commissure excursion was measured with Emotrics, and the artificial intelligence software FaceReader evaluated the intensity score (IS) of emotional expression.
Results: The mean follow-up was 40 ± 27 months. The eFACE metric showed a statistically significant (p < 0.05) postoperative improvement in the dynamic and smile scores across all groups. In the GFMT group, oral commissure with smile (75.75 ± 20.43 points), oral commissure excursion while smiling with teeth showing (32.7 ± 4.35 mm), and the intensity of happiness emotion while smiling without teeth showing (IS of 0.37 ± 0.23) were significantly lower as compared with the static group postoperatively (98.83 ± 2.86 points, p = 0.038; 41.7 ± 4.35 mm, p = 0.025; IS 0.83 ± 0.16, p = 0.01).
Conclusions: Our data suggest that secondary dynamic reconstruction with GFMT is feasible should the primary reconstruction fail. The secondary GFMT appears to improve the outcome of primary GFMT; however, the oral commissure excursion while smiling might be lower than that in patients who had static procedures as primary reconstruction.

Objectives: To assess the impact of artificial intelligence iterative reconstruction algorithms (AIIR) on image quality with phantom and clinical studies.
Methods: The phantom images were reconstructed with the hybrid iterative algorithm (HIR: Karl 3D-3, 5, 7, 9) and AIIR (grades 1-5) algorithm. Noise power spectra (NPS), task transfer functions (TTF) were measured, and additionally sharpness was assessed using a "blur metric" procedure.

Diazepam (DZP) is a muscle-relaxing, anxiety-relieving sedative drug; nonetheless, it is also an addictive drug that may be abused. This work reports on the development of a novel electrochemical nanosensor for diazepam using SiO-encapsulated-3-mercaptopropionic acid-capped AuZnCeSeS quantum dots (QDs) overcoated with a molecularly imprinted polymer (MIP) on screen-printed carbon electrodes (SPCEs). Electrochemical, spectroscopic and electron microscopic characterization of the nanomaterial and modified electrode surface was carried out and is reported herein.

Purpose: Historically, infraclavicular brachial plexus injuries (IBPIs) were considered neuropraxic injuries that would improve with nonsurgical intervention. However, more recent studies suggest that these injuries may benefit from surgical intervention. The aims of this retrospective study were to (1) describe injury patterns and associated injuries of isolated, traumatic IBPIs, (2) evaluate the concordance of preoperative ultrasound and magnetic resonance neurography with surgical findings of patients who underwent surgical intervention for IBPIs, and (3) describe outcomes of surgical intervention for these injuries.

Background: Previous studies have evidenced balance training for improving postural control in children with DCD, however none have examined how neuromuscular mechanisms controlling balance might be improved with training.
Aims: To assess the neuromuscular control of balance before and after training in children with DCD.
Methods And Procedures: Eleven children with DCD completed a six-week, game-based intervention to train balance, and lower-limb and core strength.

MiRNA therapeutics for treatment of cardiovascular disease face several problems with delivery. Encapsulation of miRNA therapeutics in cationic liposomes has shown potential to address many of these concerns with miRNA therapeutic delivery. Here we outline the formulation and characterization of cationic liposomes, capable of encapsulating and delivering miRNA therapeutics to AC16 cardiomyocyte cell lines, by microfluidics.
