Intracranial Solitary Fibrous Tumor Mimicking Meningioma.

Solitary fibrous tumor (SFT) is a clinically rare tumor derived from mesenchymal spindle cells. Central nervous system SFT represents only 0.09% of tumors occurring on the meninges, while intracranial solitary fibrous tumors (ISFT) are even more rare.

Treatment of a Patient With Meningioma With Complicated Blood Supply.

Meningiomas account for ~30% of primary intracranial tumors, making them the second most common type of brain tumor. Most meningiomas are benign, and surgical resection is curative. By utilizing 3-dimensional slicer technology for multimodal image fusion, a wealth of 3-dimensional anatomic information can be obtained, enabling more effective treatment of meningiomas with complex tumor locations and surrounding structures.

Slit Ventricle Syndrome.

Slit ventricle syndrome (SVS) is a complication after ventriculoperitoneal shunt (VPS) or cystoperitoneal shunt(CPS), mostly due to excessive drainage of cerebrospinal. The disease is most often seen in children and has a complex pathogenesis. Clinical manifestations are mainly intermittent headache, slow refilling of the shunt reservoir, and slit-like ventricles on imaging.

Intracranial Neuro-Enteric Cyst.

An intracranial nerve-enteric cyst is a relatively rare benign disease, and the main clinical manifestations are related to the location and size of the cyst. The main symptoms are caused by cyst compression. When the cyst is small without compression, it may have no obvious symptoms, and when the cyst increases to a certain degree, it may cause corresponding clinical manifestations.

Remediation of Cr(VI)-contaminated soil using combined chemical leaching and reduction techniques based on hexavalent chromium speciation.

Hexavalent chromium [Cr(VI)] has strong mobility and it can enter into deep regions of soil. Cr(VI)-contaminated soil remediation is the process of removing Cr(VI) present in deep soils and any residual Cr(VI). In this study, the Cr(VI)-contaminated soil in Chongqing was investigated, and the remediation and economic feasibility of chemical leaching and reduction combined with a soil repairing approach was explored.

Giant Electrocaloric Effect and Ultrahigh Refrigeration Efficiency in Antiferroelectric Ceramics by Morphotropic Phase Boundary Design.

Electrocaloric effect (ECE) in ferroelectric (FE)/antiferroelectric (AFE) materials offers a promising high-efficient and zero-emission solid-state cooling technology, whose materials design is usually focused on the morphotropic phase boundary (MPB) between two FE phases. This work constructs an MPB between an orthorhombic AFE and a rhombohedral FE phase in PbBaLaZrTiO (PBLZT100, = 0-0.08) ceramics and achieves a superior ECE performance.

Research on Multi-Alternatives Problem of Finite Element Model Updating Based on IAFSA and Kriging Model.

Due to insufficient test data, insufficient constraint equations and uncertain objective function, the local optimal solution and the global optimal solution of the objective function in finite element model updating may represent the actual parameters of the structure. Based on this, this paper proposes an improved artificial fish school algorithm. By combining the niche technology with the artificial fish school algorithm, the improved algorithm can systematically find multiple global optimal solutions and local optimal solutions of the objective function.

Interference of sulfide with iron ions to the analysis of Cr(Ⅵ) by Method 3060a & Method 7196a.

When Cr(Ⅵ)-contaminated soil was remediated with sulfide, due to incomplete reaction and overdose, excess sulfide could remain in the soil inducing unacceptable underestimation of residual Cr(Ⅵ) analysis, which would get worse when iron ions were introduced in. Unfortunately, the quality control policy of Method 3060a cannot distinguish the difference between real zero and false zero residual Cr(Ⅵ) when their spike recoveries are zero. This paper systematically investigated the sulfide-induced Cr(Ⅵ) reduction in Cr(Ⅵ) analysis by Method 3060a & Method 7196a.

Mir-29c Expression in Glioma and Its Effects on Tumor Cell Proliferation and Apoptosis.

Background: To investigate the expression of microRNA-29c (miR-29c) in glioma and its effects on cell proliferation and apoptosis.

Methods: A retrospective analysis was performed on 76 glioma patients in People's Hospital of Weifang, Weifang, Shandong, China from May 2013 to June 2017 (experimental group) and 63 healthy subjects in the same period (control group). qRT-PCR was used to detect the miR-29c expression.

Dynamic Model Updating for Bridge Structures Using the Kriging Model and PSO Algorithm Ensemble with Higher Vibration Modes.

This study applied the kriging model and particle swarm optimization (PSO) algorithm for the dynamic model updating of bridge structures using the higher vibration modes under large-amplitude initial conditions. After addressing the higher mode identification theory using time-domain operational modal analysis, the kriging model is then established based on Latin hypercube sampling and regression analysis. The kriging model performs as a surrogate model for a complex finite element model in order to predict analytical responses.

Ubiquitin-specific protease 28 is overexpressed in human glioblastomas and contributes to glioma tumorigenicity by regulating MYC expression.

The transcription factor MYC, which is dysregulated in the majority of gliomas, is difficult to target directly. Deubiquitinase ubiquitin-specific protease 28 (USP28) stabilizes oncogenic factors, including MYC. However, the contribution of USP28 in tumorigenesis, particularly in glioma, is unknown.
