Evidence demonstrates that brain-derived neurotrophic factor (BDNF) has a pivotal role in the pathogenesis of major depressive disorder (MDD). Precursor-BDNF (proBDNF) and mature BDNF (mBDNF) have opposing biological effects neuroplasticity, tissue-type plasminogen activator (tPA)/plasmin system is crucial cleavage processing proBDNF to mBDNF. However, very little known about tPA-BDNF pathway MDD. We examined serum protein concentrations pathway, including tPA, BDNF, tropomyosin receptor...
ABSTRACT Instrumented indentation combined with the classic Oliver–Pharr method has been widely utilized to measure elastic modulus of various materials. However, measured by instrumented spherical (ISI) is not as accurate that sharp indentation, especially at large depth. In this work, effect maximum depth on measurement ISI was deeply investigated through finite element simulations and experiments. It found errors in moduli increase significantly due inaccurate estimation contact radius...
Abstract Although, surface roughness can influence the determination of elastic moduli and indentation hardness to some extent by instrumented spherical test, limited work has been done quantitatively reveal minimize these influences. In present work, through a large number finite element (FE) simulations analyses, we clarified evolution trend determined corresponding different normalized depths ( h / R ) S q ). On this basis, an area correction method was proposed improve measurement...
Alternative pre-mRNA splicing plays critical roles in brain development. SRSF10 is a factor highly expressed central nervous system and important maintaining normal functions. However, its role neural development unclear. In this study, by conditional depleting progenitor cells (NPCs) vivo vitro, we found that dysfunction of leads to developmental defects the brain, which manifest as abnormal ventricle enlargement cortical thinning anatomically, well decreased NPCs proliferation weakened...
Fish scales serve as a dermal armor that provides protection from physical injury. Due to number of outstanding properties, fish are inspiring new concepts for layered engineered materials and next-generation flexible armors. While past efforts have primarily focused on the structure mechanical behavior ontogenetic scales, structure-property relationships regenerated received limited attention. In present study, common carp (Cyprinus carpio) acquired wild were held live in an aquatic...
Abstract Microencapsulated phase change materials (MPCMs) are usually subjected to internal pressure caused by core volume changes or external mechanical stress during service. It is of great importance for individual microcapsule achieve good performance be effective in avoiding the leakage material and providing crucial protection environment. Here, n‐octadecane was selected as different amounts titanium dioxide (TiO 2 ) nanoparticles were added into melamine formaldehyde (MF) shell,...
A panoramic dual-directional shearography system is proposed to simultaneously determine out-of-plane deformation derivatives in two directions and globally inspect the object be tested. dichroic filter (DF), a 3CCD camera, dual-wavelength light are used configuration. The coupled with corresponding imaging sensors of camera provides independent color signals shearograms. Through adjustment tilted stereo-angle DF, which offers second wavelength-dependent measurement, an additional...
Electronic speckle pattern interferometry (ESPI), a well-established technique for micro-deformation measurement, can be used to determine both in-plane and out-of-plane displacement components. Although many works in ESPI have been reported three-dimensional (3D) few focused on the simultaneous measurement of 3D deformation fields. Here we present an system that consists three sub-interferometers all components strain A 3CCD color camera, specially designed shifting stage, lasers with...
Fish scales are dermal armors with an attractive combination of resistance to puncture and flexibility. Past work has attributed this unique quality their composition the hierarchical stratification microstructure. Here, we show that ridge lines circuli contribute overall damage tolerance play a key role in "protectoflexibility" fish scales. Through application optical mechanics, channel along paths reduce effective stress intensity available for bulk fracture Furthermore, comparison line...

Finding the prediction factors for risks of post-stroke depression (PSD) is important to stroke survivors. However, most existing studies focused only on general clinical data, which limited predictive ability. To improve ability, this study proposed a comprehensive PSD risk model with social psychological factors, neurological, cognitive functional and factors. The recruited 188 patients. Patients were diagnosed by DSM-IV criteria. Predictors collected within week after stroke. Boosted...
