Proteomics study of primary and recurrent adamantinomatous craniopharyngiomas.

Background: Adamantinomatous craniopharyngiomas (ACPs) are rare benign epithelial tumours with high recurrence and poor prognosis. Biological differences between recurrent and primary ACPs that may be associated with disease recurrence and treatment have yet to be evaluated at the proteomic level. In this study, we aimed to determine the proteomic profiles of paired recurrent and primary ACP, gain biological insight into ACP recurrence, and identify potential targets for ACP treatment.

Successful surgical management of a superior cerebellar artery aneurysm in a patient with Marfan syndrome: illustrative case.

Background: Marfan syndrome, a connective tissue disorder, poses unique challenges in neurosurgery, given the fragility of vascular structures. Superior cerebellar artery (SCA) aneurysms in patients with the syndrome are rare and present distinct surgical difficulties, necessitating innovative approaches.

Observations: A 29-year-old male with Marfan syndrome presented with a subarachnoid hemorrhage from a ruptured SCA aneurysm.

Strain-modulated Ru-O Covalency in Ru-Sn Oxide Enabling Efficient and Stable Water Oxidation in Acidic Solution.

RuO is one of the benchmark electrocatalysts used as the anode material in proton exchange membrane water electrolyser. However, its long-term stability is compromised due to the participation of lattice oxygen and metal dissolution during oxygen evolution reaction (OER). In this work, weakened covalency of Ru-O bond was tailored by introducing tensile strain to RuO octahedrons in a binary Ru-Sn oxide matrix, prohibiting the participation of lattice oxygen and the dissolution of Ru, thereby significantly improving the long-term stability.

Comparative transcriptome analysis reveals key pathways and genes involved in trichome development in tea plant ().

Trichomes, which develop from epidermal cells, are considered one of the important characteristics of the tea plant [ (L.) O. Kuntze].

Effects of different curing methods on edible quality and myofibrillar protein characteristics of pork.

This study aimed to investigate the effects of standing curing (SC), tumbling curing (TC), vacuum tumbling curing (VTC) and ultrasonic-assisted curing (UAC) on the edible quality of black pork and property of myofibrillar proteins (MPs) extracted from black pork. The results showed that all curing methods could improve the marinating absorptivity and the gel water retention of black pork, the solubility and surface hydrophobicity of myofibrillar proteins, and reduce the cooking loss and shear force of black pork, the hydrogen bond content of myofibrillar proteins and the gel whiteness compared with the control group (SC). The result of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed that the concentration of protein bands by VTC treatment was decreased obviously.

Dissipation behaviour, residue analysis, and dietary safety evaluation of chlorfenapyr on various vegetables in China.

Chlorfenapyr has been widely used in recent years to control a variety of pests on fruit and vegetables. Cabbage, leek, asparagus, and chive are four of the most common green foods consumed word wide; their pesticide residue issues have also received more attention. Therefore, studies on the residue analysis, degradation evaluation and dietary risk assessment based on the complete residue definition of chlorfenapyr on these four vegetables were essential and urgently needed.

Chromatographic analysis and residue degradation of phenamacril and difenoconazole on strawberries.

Strawberries are widely cultivated and highly consumed globally, but pests and diseases can severely affect yields. Phenamacril and difenoconazole are high-efficacy pesticides and the mixture of these two pesticides offers a satisfactory option for disease control. In this study, an optimised QuEChERS method combined with dispersive solid-phase extraction purification before injection for simultaneously determining the residues of phenamacril-difenoconazole mixture on strawberries was developed and validated using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).

Aggressive resection of craniopharyngioma achieved by drilling the tuberculum sellae/planum sphenoidale using a frontal basal interhemispheric approach: A review of 55 cases.

Objective: The frontal basal interhemispheric approach (FBIA) is preferable for resection of craniopharyngioma (CP), achieving desirable total resection rates in early reports of lesions located in the suprasellar region to the third ventricle. For tumours that have created a larger obstruction of the tuberculum sellae and planum sphenoidale, aggressive resection in the intrasellar region and medial wall of the cavernous sinus is not feasible compared to improving tumour visualization by drilling the tuberculum sellae and planum sphenoidale. In a report of drilling the sellar tuberculum and sphenoid planum, drilling allowed the direct visualization of tumours invading the intrasellar region and medial wall of the cavernous sinus.

Ultra-high adsorption capacity of MgO/SiO composites with rough surfaces for Congo red removal from water.

Due to its high isoelectric point, relative safety and low environmental toxicity, magnesium oxide has attracted much attention for its role in the removal of toxic dyes from wastewater. Herein, MgO-SiO composites with rough surfaces were synthesized by a one-step method. The as-prepared composites were characterized for the adsorption of Congo red from water using adsorption kinetics and isotherms.

The Incidence and Risk Factors of Postoperative Entrapped Temporal Horn in Trigone Meningiomas.

Objective: To determine risk factors for the occurrence of postoperative entrapped temporal horn (ETH), a specific form of isolated hydrocephalus that is a severe complication after resection of lateral ventricular trigone tumors, following trigone meningioma surgery.

Methods: A retrospective review was performed of 121 cases of trigone meningiomas surgically treated between November 2011 and March 2015 in Beijing Tiantan Hospital. Patient demographics, imaging features, surgical procedures, and postoperative complications were evaluated by statistical analysis.

Prognostic factors for patients with atypical or malignant meningiomas treated at a single center.

The purpose of this study is to summarize our experience in managing patients with an atypical or malignant meningioma at our institution, with a specific focus on determining the prognostic factors for treatment outcome. We reviewed the records of 126 patients with atypical or malignant meningiomas from January 2001 to August 2011. Data collected included gender, age, Karnofsky Performance Scale (KPS) score, pathology results, cleavability, and bone invasion.

Clinical, radiological, and pathological features of 26 intracranial and intraspinal malignant peripheral nerve sheath tumors.

Object: Intracranial and intraspinal malignant peripheral nerve sheath tumors (MPNSTs) are rarely reported because of their extremely low incidence. Knowledge about these tumors is poor. In this study the authors aimed to analyze the incidence and clinical, radiological, and pathological features of intracranial and intraspinal MPNSTs.
