Objective: To evaluate the effects of different SARS-CoV-2 inactivation methods on the blood concentration of colistin sulfate.

Methods: A colistin sulfate reference substance, a quality control plasma sample, and a clinically measured sample were transferred and heated in a 56 °C water batch for 30 min or irradiated under an ultraviolet (UV) lamp for 60 min to examine the stability of the reference solution and quality control plasma sample. Statistical analysis was conducted for the concentration of the clinically measured sample before and after inactivation with the intraclass correlation coefficient (ICC) method, the Passing-Bablok regression, and the Bland-Altman analysis.

Identification of Ferroptosis-Related Genes in Heart Failure Induced by Transverse Aortic Constriction.

Background: Heart failure (HF) is a common clinical syndrome due to ventricular dysfunction and is a major cause of mortality worldwide. Ferroptosis, marked by excessive iron-dependent lipid peroxidation, is closely related to HF. Therefore, the purpose of this study is to explore and validate ferroptosis-related markers in HF by bioinformatics analysis and animal experiments validation.

Effect of HMGB1 and RAGE on brain injury and the protective mechanism of glycyrrhizin in intracranial‑sinus occlusion followed by mechanical thrombectomy recanalization.

The key to successful treatment of cerebral venous‑sinus occlusion (CVO) is the rapid recanalization of the sinus following venous‑sinus occlusion; however, rapid recanalization of the sinus may also cause secondary cerebral injury. The present study examined mechanical thrombectomy‑related brain injury and the possible molecular mechanisms following CVO recanalization, and investigated the protective effect of glycyrrhizin (GL) in CVO recanalization. The cerebral venous sinus thrombosis (CVST) model was induced in rats using 40% FeCl3.

Serum Ngb (Neuroglobin) Is Associated With Brain Metabolism and Functional Outcome of Aneurysmal Subarachnoid Hemorrhage.

Background and Purpose- Hypoxic-ischemic brain damage is a well-recognized physiopathologic mechanism after aneurysmal subarachnoid hemorrhage (aSAH). The Ngb (neuroglobin) is a hemoprotein predominantly expressed in the brain with a high affinity for oxygen. Relationship between serum Ngb level and brain metabolism in aSAH patients has not been investigated previously.

The role of high mobility group box 1 protein in acute cerebrovascular diseases.

The occurrence and development of acute cerebrovascular diseases involves an inflammatory response, and high mobility group box protein 1 (HMGB1) is a pro-inflammatory factor that is expressed not only in the early-injury stage of disease, but also during the post-repair process. In the initial stage of disease, HMGB1 is released into the outside of the cell to participate in the cascade amplification reaction of inflammation, causing vasospasm, destruction of the blood-brain barrier and apoptosis of nerve cells. In the recovery stage of disease, HMGB1 can promote tissue repair and remodeling, which can aid in nerve function recovery.

Endoscopic third ventriculostomy (ETV) provides a physiological restoration of cerebrospinal fluid and a shunt-free option for hydrocephalus children. Continuous developments in techniques and instruments have improved ETV as the first-line treatment. This paper focuses on the recent advances in surgical techniques, instruments, predictive models, imaging tools, and new cohort studies.

Suppression of microRNA-130b inhibits glioma cell proliferation and invasion, and induces apoptosis by PTEN/AKT signaling.

Glioblastoma is the most common malignant brain tumor in adults and is characterized by extensive proliferation and the diffused invasion of tumor cells. Due to the intricate signaling pathways involved in glioma progression, more effective targeted therapies and prognostic biomarkers in clinical practice are required. The suppression of proto-oncogene function or recovery of tumor suppressor gene function remains one of the primary approaches in gene therapy.

Analysis of Factors Related to Hypopituitarism in Patients with Nonsellar Intracranial Tumor.

Objective: Previous studies have suggested that postoperative hypopituitarism in patients with nonsellar intracranial tumors is caused by traumatic surgery. However, with development of minimally invasive and precise neurosurgical techniques, the degree of injury to brain tissue has been reduced significantly, especially for parenchymal tumors. Therefore, understanding preexisting hypopituitarism and related risk factors can improve perioperative management for patients with nonsellar intracranial tumors.

miR-130b regulates the proliferation, invasion and apoptosis of glioma cells via targeting of CYLD.

MicroRNAs are short non-coding RNAs that play important roles in gliomas. However, the role of miR-130b in glioma remains unclear. In the present study, miR-130b expression was upregulated in glioma tissues and cell lines.

TPX2 promotes glioma cell proliferation and invasion via activation of the AKT signaling pathway.

Glioblastoma multiforme (GBM) is the most common and most malignant type of primary adult brain cancer. The most common phenotype associated with GBM is cellular invasion; however, the molecular mechanisms governing this process are poorly understood. Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is a nuclear protein with roles in cellular proliferation and mitotic spindle assembly.

Recombinant human soluble thrombomodulin protects against brain injury in a CVST rat model, via downregulation of the HMGB1-RAGE axis.

Cerebral venous sinus thrombosis (CVST) is a distinct cerebrovascular disorder, and ~50% of CVST patients progress to cerebral venous infarction, resulting in elevation of cerebral venous pressure. Anticoagulation is the standard initial treatment and is associated with a reduced relative risk of mortality and dependency. Recombinant human soluble thrombomodulin (rhs‑TM) is a promising therapeutic natural anticoagulant comparable to antithrombin, tissue factor pathway inhibitor, and activated protein C.

MicroRNA-130b promotes cell proliferation and invasion by inhibiting peroxisome proliferator-activated receptor-γ in human glioma cells.

MicroRNA-130b (miR-130b) is a novel tumor-related miRNA that has been found to be involved in several biological processes. However, there is limited evidence regarding the role of miR-130b in the tumorigenesis of human gliomas. In the present study, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assays were used to quantify miR-130b expression levels in human glioma tissues and glioma cell lines (U251, U87, SNB19 and LN229).

MiR-218 inhibits the tumorgenesis and proliferation of glioma cells by targeting Robo1.

Background: Malignant glioma is the most common primary brain tumors directly correlated with the high mortality and poor prognosis in clinical practice. MicroRNAs (miRNAs or miRs) influence numerous cancer-relevant processes including cell proliferation, differentiation and metabolism. However, the role of microRNA in malignant glioma is largely unknown.
