This study designed a composite material with internal synergistic effects among multiple components to achieve highly selective adsorption of Cu (II). Through controlled synthesis, the FeO/MnO(3 1 0)/ZIF-67 composite was successfully fabricated, leading to significant improvement in adsorption selectivity, capacity, and adsorption rate. The experimental results showed that the composite is of outstanding selectivity in the adsorption of Cu (II), with a partition coefficient K of Cu (II) that was 2.

The DFT calculations were performed to screen the selective adsorption capability of the facets and demonstrated that the MnO (3 1 0) facet has an excellent performance in selective adsorption of Pb (II) among all facets. The validity of DFT calculations was verified by comparing with the experimental results.

The goal of this study was to detail the association between folate and vitamin B12 with cognitive performance. We analyzed cross-sectional data of older adults (≥60 y; = 2204) from the NHANES (National Health and Nutrition Examination Surveys) cohort from 2011-2014.

Accumulating evidence suggests that neuroinflammation is one of the major contributors to the development of PNDs, but the underlying mechanisms remain unclear.
Methods: qPCR and ELISA analysis were used for detecting LCN2 and cytokine levels.
Microglia, which serve as the defensive interface of the nervous system, are activated in many neurological diseases. Their role as immune responding cells has been extensively studied in the past few years. Recent studies have demonstrated that neuronal feedback can be shaped by the molecular signals received and sent by microglia.

Pyroptosis is characterized by caspase-1 dependence and the release of a large number of pro-inflammatory factors. LncRNA-Fendrr is associated with a variety of diseases, but Fendrr has not been studied in diabetic cerebral I/R.
View Article and Find Full Text PDFTransient receptor potential canonical 6 (TRPC6) channel is an important non-selective cation channel with a variety of physiological roles in the central nervous system. Evidence has shown that TRPC6 is involved in the process of experimental stroke; however, the underlying mechanisms remain unclear. In the present study, the role of astrocytic TRPC6 was investigated in an oxygen-glucose deprivation cell model and middle cerebral artery occlusion (MCAO) mouse model of stroke.

Background: The present study aimed to investigate the incidence and extent of difficult airway management in patients with massive retrosternal goiter.
Design: An 8-year retrospective analysis was performed to identify patients who underwent massive retrosternal thyroidectomy. A total of 22 cases were identified as giant retrosternal goiter, followed by a review of each patient's preoperative computerized tomography imaging.
Stroke is one of the leading causes of death worldwide. Accumulating evidence suggests that NLRP3 inflammasome activation plays an important role in ischemic stroke injury. However, the existence of the NLRP3 inflammasome in astrocytes remains controversial.

Since the coronavirus disease 2019 (COVID-19) affects the cardio-pulmonary function of pregnant women, the anesthetic management and protection of medical staff in the cesarean section is significantly different from that in ordinary surgical operation. This paper reports a case of cesarean section for a woman with COVID-19, which was successfully performed in the First Affiliated Hospital of Zhejiang University School of Medicine on February 8, 2020. Anesthetic management, protection of medical staff and psychological intervention for the pregnant woman during the operation were discussed.

Stroke remains a leading cause of death, disability, and medical care burden worldwide. However, transformation from laboratory findings toward effective pharmacological interventions for clinical stroke has been unsatisfactory. Novel evidence has been gained on the underlying mechanisms and therapeutic potential related to the transient receptor potential (TRP) channels in several disorders.

However, the expression and function of lncRNA TUG1 in cerebral ischaemia/reperfusion injury have not been reported yet. In this study, we found that LncRNA TUG1 expression was significantly up-regulated in cultured MA-C cells exposed to OGD/R injury, while similar results were also observed in MCAO model.

The present study aimed to investigate the role and possible mechanism of TIM-1 in cerebral ischemia-reperfusion injury.
Methods: Western blot was used to detect TIM-1 and apoptosis-related protein expression, whereas TIM-1 mRNA was examined using quantitative real-time reverse transcription PCR.
Perioperative neurocognitive disorders (PND) are common complications observed in surgical patients, but there are no effective treatments and the detailed mechanisms remain largely unknown. In this study, transcriptome analysis was performed to investigate the hippocampal changes after surgery and underlying molecular mechanisms of PND. Tibial fracture surgery was performed in 3-4 months old C57BL/6J mice to mimic human orthopedic surgery.

In the present study, we aimed to determine whether miR‑29a played a protective role in oxygen glucose deprivation (OGD) injury via regulation of the water channel protein aquaporin 4 (AQP4). Real‑time PCR and western blotting were used to assess miR‑29a levels and AQP4 protein levels, respectively.

This meta-analysis was conducted for the purpose of evaluating whether GDFT impacts on occurrence of postoperative ileus and whether its application is worthwhile in gastrointestinal surgery.
Methods: A systematic search of RCTs compared GDFT with other fluid management in patients undergoing gastrointestinal surgery from the PubMed, Web of Science, Embase, Cochrane Library databases was implemented.
Background/aims: Our study aims to characterize functions of ZBTB16 gene in the process of intramuscular fat (IMF) deposition and metabolism of bovine, thereby providing insights into mechanisms for the use of ZBTB16 in fat management.
Methods: Primary preadipocytes derived from bovine IMF tissue were isolated and used as the in vitro cell model. An adenovirus Ad-ZBTB16 was transfected into bovine preadipocytes to overexpress the ZBTB16 gene.
The objective of this article was to evaluate in vitro effect of grape seed procyanidin extract (GSPE) on differentiation, proliferation, and lipolysis of porcine adipocytes, providing a molecular basis for the use of GSPE in pig fat regulation. Primary preadipocytes isolated from subcutaneous adipose tissue of pigs were used as the in vitro cell model. Treatment of GSPE repressed preadipocyte differentiation, as evidenced by reduced lipid accumulation, decreased mRNA expressions of peroxisome proliferator-activated receptor gamma (PPARγ) and fatty acid-binding protein 4 (FABP4), as well as enhanced expressions of preadipocyte factor-1.

Cerebral blood flow autoregulation is physiologically protective mechanism to maintain the stability of cerebral blood flow. Once autoregulation is impaired, the cerebral blood flow fluctuates with blood pressure, leading to the risk of brain ischemia or cerebral hyperemia. Multiple research results indicate that cerebral blood flow can be monitored indirectly and continuously with transcranial Doppler, near infrared spectroscopy or ICP.
