Experimental Feasibility Study of TRAIL Gene Transfected into Neural Stem Cells.

Aim: To investigate the feasibility of transfecting the TNF-related apoptosis-inducing ligand (TRAIL) gene into neural stem cells (NSCs) in vitro, and explore whether NSCs retain their proliferative and differentiated activities after transfection.

Material And Methods: NSCs were obtained from fetal mouse brains, cultured in serum-free medium and identified by immunofluorescence staining. Lentivirus vector solution containing green fluorescent protein (GFP) gene was added to the NSCs based on the multiplicity of infection (MOI).

A foreign body that has been left for 20 years causes a pseudoaneurysm of the middle cerebral artery: a case report.

Background: We report a patient with extensive subarachnoid hemorrhage caused by the rupture of a middle cerebral artery pseudoaneurysm from a foreign body that had been left for two decades.

Case Presentation: A 74-year-old male patient from Han nationality was admitted to the emergency department of our hospital with impaired consciousness for 1 hour. Cranial computed tomography examination indicated a massive subarachnoid hemorrhage with intraventricular blood accumulation, and a high-density short strip dense shadow was seen in the M1 segment of the right middle cerebral artery, considering the possibility of a foreign body.

Gas Chromatography-Mass Spectrometry Technology: Application in the Study of Inflammatory Mechanism in COVID-19 Patients.

SARS-CoV-2 infection in the human body induces a severe storm of inflammatory factors. However, its specific mechanism is still not clear. Gas chromatography-mass spectrometry (GC-MS) technology is expected to explain the possible mechanism of the disease by detecting differential metabolites.

miR-145-5p targets MMP2 to protect brain injury in hypertensive intracerebral hemorrhage via inactivation of the Wnt/β-catenin signaling pathway.

Background: Differences in microRNA (miRNA) expression after hypertensive intracerebral hemorrhage (HICH) have been reported in human and animal models. miRNA-145 plays an important role in vascular endothelial cells. The purpose of this work was to determine the role of miR-145-5p in HICH and the molecular mechanisms by which it acts.

Dihydroartemisinin-Loaded Chitosan Nanoparticles Inhibit the Rifampicin-Resistant by Disrupting the Cell Wall.

Tuberculosis (TB) caused by (MTB) is a deadly infection, and increasing resistance worsens an already bad scenario. In this work, a new nanomedicine antibacterial agent, based on dihydroartemisinin (DHA) and chitosan (CS), has been successfully developed to overcome MTB's drug-resistant. To enhance DHA's solubility, we have prepared nanoparticles of DHA loaded CS by an ionic crosslinking method with sodium tripolyphosphate (STPP) as the crosslinking agent.

[Efficient Photolysis of Acid Orange 7 Using Low-frequency Electrodeless Lamp].

Using the low-frequency electrodeless lamp (LFEL) of 40 watts, the photodegradation of Acid orange 7 (A07) in water solution was studied. By applying a special reactor in which the light source was placed under the water, photodegradation efficiency of A07 using LFEL was compared with that using common UV mercury lamp. A few small degradation products were detected by GC-MS.
