Mineral trapping of carbon dioxide: Rapid hydrothermal synthesis experiments and carbon sequestration potential of dawsonite.

Dawsonite, as a natural CO tracing mineral, is intimately associated with CO injection and serves as a crucial mineral for geological carbon sequestration. The massive and stable presence of dawsonite in the geological background is a key consideration for CO mineralization capture and plays a significant role in identifying CO geological burial sites. To investigate the optimal conditions for the rapid synthesis of dawsonite using CO, we conducted comparative experiments to examine the three primary influencing factors: temperature (100 °C, 120 °C, 140 °C, 160 °C, 180 °C, and 200 °C), pH (8.

Upregulation of miR-519 enhances radiosensitivity of esophageal squamous cell carcinoma trough targeting PI3K/AKT/mTOR signaling pathway.

Purpose: MicroRNA-519 (miR-519) has been previously reported to function as a tumor suppressor in several types of malignancies. This study aimed to probe the biological role of miR-519 in esophageal squamous cell carcinoma (ESCC).

Methods: qRT-PCR was utilized to test the miR-519 expression level in ESCC tissues and cells.

The inhibition of BDNF/TrkB/PI3K/Akt signal mediated by AG1601 promotes apoptosis in malignant glioma.

Malignant glioma is the most aggressive primary brain tumor and has a poor survival rate. Even if extensive methods are preformed to treat glioma, the mortality rate is still very high. It is necessary for discovering and developing new drugs for malignant glioma treatment.

LINC00473/miR-374a-5p regulates esophageal squamous cell carcinoma via targeting SPIN1 to weaken the effect of radiotherapy.

Esophageal squamous cell carcinoma (ESCC) is the most prevalent type in esophageal cancers. Despite accumulating achievements in treatments of ESCC, patients still suffer from recurrence because of the treatment failures, one of the reasons for which is radioresistance. Therefore, it is a necessity to explore the molecular mechanism underlying ESCC radioresistance.

LBX2-AS1 is activated by ZEB1 and promotes the development of esophageal squamous cell carcinoma by interacting with HNRNPC to enhance the stability of ZEB1 and ZEB2 mRNAs.

Long non-coding RNAs (lncRNAs) are a group of transcripts, which can regulate the progression of esophageal squamous cell carcinoma (ESCC). According to the data of TCGA, Ladybird homeobox 2 antisense RNA 1 (LBX2-AS1) is a highly expressed lncRNA in ESCC samples. Herein, we chose it for further study.

Practice of cervical end-esophageal exteriorization in patients with severe intrathoracic anastomotic leakage after esophagectomy.

Objective: This study aimed to summarize the clinical experience of severe intrathoracic anastomotic leakage encountered in clinical practice by using cervical end-esophageal exteriorization.

Methods: We undertook a retrospective review of four patients who developed severe anastomotic leakage after subtotal esophagectomy at our department. Four patients with a life-threatening condition and failed conservative management were re-operated on from the original incision using an exteriorized cervical end-esophageal gastric conduit.

Effects of Different Training Loads on Emotional State and mRNA and Protein Expressions of N-Methyl-D-Aspartate Receptor Subunits, Postsynaptic Density 95, and Kinesin Family Member 17 in Hippocampus of Rats.

BACKGROUND Emotional state can be affected by different training loads. The aim of this study was to explore the changes of rat emotional state, as well as the mRNA and protein expressions of N-methyl-D-aspartate receptors (NMDARs), postsynaptic density 95 (PSD-95), and kinesin family member 17 (KIF-17) in the hippocampus, by long-term moderate-intensity and high-intensity training models in rats. MATERIAL AND METHODS The exercise model of SD rats was set up by treadmill running of moderate and high intensities for 4 weeks.

Impaired hippocampal synaptic plasticity and NR2A/2B expression ratio in remifentanil withdrawal rats.

Remifentanil is a kind of synthetic opioid which has gained wide clinical acceptance by anesthesiologists. In this study, we attempted to test whether withdrawal effects on learning mechanisms can be triggered by repeated low-dose remifentanil treatment. Male Sprague-Dawley (SD) rats were subjected to remifentanil (50μg/kgs.

In vitro assessment of the effect of methylene blue on voltage-gated sodium channels and action potentials in rat hippocampal CA1 pyramidal neurons.

Methylene blue (MB) is a vital dye to allow better visualization and marker of parathyroid glands. The compound causes a toxic encephalopathy in clinical observations and some neuronal adverse effects in experimental studies. Of neurotoxic effects, reduced field excitatory postsynaptic potentials (fEPSPs) in hippocampal slice cultures and apoptosis induced in neurons by MB, suggest that MB may affect electrophysiological properties in neurons.

Effects of maternal food restriction on physical growth and neurobehavior in newborn Wistar rats.

Maternal nutrition plays a critical role in physical growth and neurobehavior of offspring. The aim of this study was to assess the nature of maternal undernutrition on the physical growth and neurobehavior of newborn male and female rat pups. To attain this aim, a model of maternal 50% food restriction (FR50) was induced in Wistar rats.

Perinatal food restriction impaired spatial learning and memory behavior and decreased the density of nitric oxide synthase neurons in the hippocampus of adult male rat offspring.

Perinatal undernutrition has adverse effects on brain physiology as well as learning and memory activity. However, the mechanism is still incompletely understood. Nitric oxide (NO) synthesized by neuronal nitric oxide synthase (nNOS) has important roles in neuronal survival and synaptic plasticity as well as contributes to the learning and memory task.

Targeted migration of mesenchymal stem cells modified with CXCR4 gene to infarcted myocardium improves cardiac performance.

With the goal of devising a non-invasive cell therapy for cardiac repair that may be well tolerated by patients with myocardial infarction (MI), this study evaluated the efficacy of intravenous infusion of genetically modified mesenchymal stem cells (MSCs) overexpressing CXC chemokine receptor 4 (CXCR4). CXCR4 is the cognate receptor for stromal-derived factor-1 (SDF-1), a chemokine required for homing of progenitor cells to ischemic tissues. In this study, retrovirally transduced MSCs constitutively expressing CXCR4 (CXCR4-MSCs) were delivered intravenously 24 hours after coronary occlusion/reperfusion in rats.
