Object The authors conducted a large retrospective study in which they evaluated the efficacy of intraoperative electromyography (EMG) monitoring facial musculature during microvascular decompression (MVD) and assessed predictive value lateral spread response (LSR) as prognostic indicator for treatment outcome hemifacial spasm (HFS). Methods undertook MVD 300 consecutive patients with HFS. were divided into two groups based on whether LSR disappeared or persisted following decompression....

Because of a lack an appropriate animal model system and the inaccessibility human oligodendrocytes in vivo, X-linked adrenoleukodystrophy (X-ALD)-induced pluripotent stem cells (iPSCs) would provide unique cellular for studying etiopathophysiology development therapeutics X-ALD.We generated characterized iPSCs 2 major types X-ALD, childhood cerebral ALD (CCALD) adrenomyeloneuropathy (AMN), differentiated them into neurons. We evaluated disease-relevant phenotypes by pharmacological genetic...

The generation of disease-specific induced pluripotent stem cell (iPSC) lines from patients with incurable diseases is a promising approach for studying disease mechanisms and drug screening. Such innovation enables to obtain autologous sources in regenerative medicine. Herein, we report the characterization iPSCs fibroblasts sporadic or familial diseases, including Parkinson's (PD), Alzheimer's (AD), juvenile-onset, type I diabetes mellitus (JDM), Duchenne muscular dystrophy (DMD), as well...

Recently, there has been development toward metal additive manufacturing (MAM) because of its benefits like fabrication complex geometries, waste minimization, freedom design, and low-cost customization. Despite these advantages, the influence processing parameters on properties MAM products is neither well understood nor easily predictable. In this study, explainable machine learning (xML) models were applied to predict understand geometry types defects in MAM-processed Fe-Ni alloys....

Repair offers significant time—cost savings and durability by reusing existing parts efficiently. Prior to implementation of repaired parts, it is crucial clarify mechanical properties deformation mechanisms ensure proper performance. In this study, a repair deposition was performed on the groove wrought stainless steel 316L using same material powder. The sample exhibited an excellent combination ductility strength (T.EL: 58%, YS: 407 MPa, UTS: 673 MPa) compared counterpart. With...

Direct energy deposition (DED) has gained attention in the field of metal repair because its ability to integrate additively deposited material with preexisting components. Having beneficial aspects depositing right material, DED is evaluated best option for deposition. Machining grooves damaged components common first repair, which necessary remove cracked or and provide suitable geometry Preprocessing as grooving commonly applied prevent propagation cracks tears. However, challenges such...

Inorganic nanoparticles have been widely applied to various industrial fields and biological applications. However, the question as whether are more efficiently absorbed into systemic circulation than bulk-sized materials remains be unclear. In present study, physico-chemical dissolution properties of most extensively developed inorganic nanoparticles, such silica (SiO2), titanium dioxide (TiO2), zinc oxide (ZnO), were analyzed, compared with particles. Furthermore, bioavailability versus...

The configurational design of heterostructures has received considerable attention to achieve a superior combination strength and ductility. Although heterostructuring for enhanced tensile properties been widely analyzed, studies on the effect heterogeneity sheet formability are still insufficient. Sheet metal is one most crucial factors determining hetero-materials' industrial utilization. To broaden applicability heterostructured layered materials, investigating effects in structure...

Abstract Protein thermostability is a crucial issue in the practical application of enzymes, such as inorganic synthesis and enzymatic polymerization phenol derivatives. Much attention has been focused on enhancement numerous successes have achieved through protein engineering methods. Despite fruitful results based random mutagenesis, it was still necessary to develop novel strategy that can reduce time effort involved this process. In study, rapid effective described for increasing thermal...

We have successfully prepared layered double hydroxide (LDH) nanomaterials containing calcium and aluminum ions in the framework (CaAl-LDH). The surface of CaAl-LDH was coated with enteric polymer, Eudragit®L 100 order to protect from fast dissolution under gastric condition pH 1.2. X-ray diffraction patterns, Fourier transform infrared spectroscopy, scanning electron transmission microscopy revealed that pristine LDH well having hydrocalumite structure, polymer effectively without...
