 BACKGROUND It is challenging to assess blepharospasm (BSP) and hemifacial spasm (HFS) patients, since these patients exhibit a wide range of amplitudes of eyelid movements. In order to quantify these movements, a mathematical algorithm, Fast Fourier Transform (FFT) can be employed to convert the signal from the time domain to the frequency domain. The result of this quantification represents the energy generated during the eyelid movements. In order to objectively assess the therapeutic effects of botulinum toxin in these patients, we evaluated the energy generated by the upper eyelid during spontaneous eyelid movements before and after treatment. METHODS Thirty-nine patients with BSP and HFS were evaluated before and 30 days after receiving onabotulinumtoxinA injections. A high-speed camera and micro light-emitting diodes were used to register the spontaneous eyelid movements. The result of the quantification obtained using FFT permitted to assess the activity associated with the eyelid movements. RESULTS We studied 78 eyelids. The total energy generated during spontaneous eyelid movements was significantly reduced after treatment in the BSP patients (p = 0.0018) and on the affected side in the HFS (p = 0.0058) patients. CONCLUSIONS The assessment of the energy generated by the upper eyelid during spontaneous eyelid movements enabled us to measure the therapeutic effects of botulinum toxin in patients with these conditions. The use of this system could enable customized and fine adjustments to botulinum toxin doses based on each patient's needs. This article is protected by copyright.

Few studies have targeted pediatric-specific scaffolds.  https://www.selleckchem.com/ALK.html  We sought to assess safety, efficacy, and short-term performance of a dedicated drug-free PBBS pediatric scaffold compared to a standard low-profile bare metal stent (BMS) in central and peripheral arteries of weaned piglets. METHODS Forty-two devices (22 Elixir poly-L-lactic-acid-based pediatric bioresorbable scaffolds [BRS] [6 × 18 mm] and 20 control BMS Cook Formula 418 [6 × 20 mm]) were implanted in the descending aorta and pulmonary arteries (PAs) of 14 female Yucatan piglets. Quantitative measurements were collected on the day of device deployment and 30 and 90 days postimplantation to compare device patency and integrity. RESULTS The BRS has a comparable safety profile to the BMS in the acute setting. Late lumen loss (LLL) and percent diameter stenosis (%DS) were not significantly different between BRS and BMS in the PA at 30 days. LLL and %DS were greater for BRS versus BMS in the aorta at 30 days postimplantation (LLL difference 0.96 ± 0.26; %DS difference 16.15 ± 4.51; p  less then  .05). At 90 days, %DS in the aortic BRS was less, and PA BRS LLL was also less than BMS. Histomorphometric data showed greater intimal proliferation and area stenosis in the BRS at all time points and in all vessels. CONCLUSIONS A dedicated PBBS pediatric BRS has a favorable safety profile in the acute/subacute setting and demonstrates characteristics that are consistent with adult BRSs. © 2020 Wiley Periodicals, Inc.Dynamin-Related-Protein 1 (DRP1) critically regulates mitochondrial and peroxisomal fission in multicellular organisms. However, the impact of DRP1 on other organelles, especially its direct influence on ER functions remains largely unclear. Here, we report that DRP1 translocates to endoplasmic reticulum (ER) in response to β-adrenergic stimulation. To further investigate the function of DRP1 on ER-lipid droplet (LD) dynamics and the metabolic subsequences, we generated an adipose tissue-specific DRP1 knockout model (Adipo-Drp1flx/flx ). We found that the LDs in adipose tissues of Adipo-Drp1flx/flx mice exhibited more unilocular morphology with larger sizes, and formed less multilocular structures upon cold exposure. Mechanistically, we discovered that abnormal LD morphology occurs because newly generated micro-LDs fail to dissociate from the ER due to DRP1 ablation. Conversely, the ER retention of LDs can be rescued by the overexpressed DRP1 in the adipocytes. The alteration of LD dynamics, combined with abnormal mitochondrial and autophagy functions in adipose tissue, ultimately lead to abnormalities in lipid metabolism in Adipo-Drp1flx/flx mice. © 2020 Federation of American Societies for Experimental Biology.OBJECTIVE To determine the biomechanical properties of pedicle screw external fixation (PDW) for equine mandibular fracture repair and compare PDW to locking compression plates (LCP). STUDY DESIGN Cadaveric study. SAMPLE POPULATION Sixteen adult equine mandibles. METHODS Four mandibles were kept intact, while 12 were osteotomized and stabilized with the LCP or PDW construct (6 mandibles/group). Failure, stiffness, and yield were calculated from quasi-static ramp to failure and compared with previous analysis of mandibular fracture constructs. Tooth root involvement and method of failure were determined from radiographs and videos. RESULTS Locking compression plate constructs achieved greater stiffness and load at failure (4656 ± 577 N-m/radian, 558 ± 27 N-m P  less then  .05) compared with PDW constructs (2626 ± 127 N-m/radian, 315 ± 48 N-m). Yield did not differ between types of fixation (369 ± 57 N-m, 193 ± 35 N-m, P = .145). Tooth involvement was noted in two LCP constructs with failure via bone fracture.  https://www.selleckchem.com/ALK.html  Pedicle screw external fixation constructs failed via wire unraveling and screw bending. CONCLUSION Locking compression plate fixation increased stiffness and failure of constructs but did not influence yield. It also increased the risk of tooth root involvement relative to fixation with PDW. Compared with another study, PDW offered stiffness and failure similar to an intraoral splint with interdental wires, external fixator (EF), and external fixator with wires (EFW) and yield similar to an EF, an EFW, and a dynamic compression plate. CLINICAL RELEVANCE Pedicle screw external fixation offers biomechanical stability comparable to other relevant mandibular fixation techniques and reduces the risk of tooth root damage compared with LCP fixation. © 2020 The American College of Veterinary Surgeons.
