Controlling shareholders' share pledge and share repurchase notices of listed companies.

States encourage listed companies to use stock repurchase to elevate the market value of listed firms. After China's promulgation of the new Company Law in 2018, the number of listed companies that issued stock repurchase notices has increased, and the frequency is also increasing. But whether market value management is the real incentive for the action remains debatable.

[Knockdown of IL-33 suppresses the expression of inflammatory factors and NLRP3 to inhibit the inflammatory response in asthmatic mice].

Objective To explore the regulatory mechanism of interleukin-33 (IL-33) on the inflammatory response in asthmatic mice. Methods Using 10 μg/mL of lipopolysaccharide (LPS) to establish a cellular inflammation model of mouse bone marrow mesenchymal stem cells (BMMSCs), the cells were divided into three groups: small interfering RNA of IL-33(si-IL-33) group, IL-33 overexpression (IL-33-OE) group, and model group, based on the transfection status of si-IL-33 plasmid and IL-33-OE plasmid. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect mRNA expression of IL-33, nucleotide binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3), IL-1β and IL-6.

The scar that takes time to heal: A systematic review of COVID-19-related stigma targets, antecedents, and outcomes.

COVID-19, as a crucial public health crisis, has affected our lives in nearly every aspect. Besides its major health threats, COVID-19 brings severe secondary impacts, one of which is the rise of social stigma. Although numerous studies have examined the antecedents and outcomes of COVID-19-related stigma, we still lack a systematic understanding of who is being stigmatized during the COVID-19 pandemic, what exacerbates COVID-19-related stigma, and what impacts COVID-19-related stigma has on victims.

Cathepsin L-containing exosomes from α-synuclein-activated microglia induce neurotoxicity through the P2X7 receptor.

Uncontrolled microglial activation is pivotal to the pathogenesis of Parkinson's disease (PD), which can secrete Cathepsin L (CTSL) to affect the survival of neurons in the PD patients; however, the precise mechanism has yet to be determined. We demonstrated for the first time that CTSL was mostly released by exosomes derived from α-Syn-activated microglia, resulting in neuronal damage and death. The elevation of CTSL activity was blocked by GW4869, suggesting a critical role for exosomes in mediating CTSL release.

From September 2017 to early September 2019, patients screened for high-risk HPV positive or abnormal cervical liquid-based cytology were retrospectively analyzed and diagnosed with LSIL by cervical biopsy were recruited.

Highly efficient Hg removal via a competitive strategy using a Co-based metal organic framework ZIF-67.

The stronger coordination ability of mercury ions with organic ligands than the metal ions in metal organic framework (MOFs) provides an accessible way to separate mercury ions from solution using specific MOFs. In this study, a Co-based MOF (ZIF-67, Co(mIM)) was synthesized. It did not introduce specific functional groups, such as -SH and -NH, into its structure through complicated steps.

Optimized Mo-doped IrO anode for efficient degradation of refractory sulfadiazine.

Electrochemical advanced oxidation processes (EAOPs) is considered to be an efficacious method to degrade antibiotics. However, the performance of the anode has become the main limiting factor of this technology. In this study, due to the electron-deficient characteristics and the improvement of OER performance of Mo, we chose to use thermal decomposition to incorporate Mo into IrO to prepare anodes with industrial applicability.

Achieving Active and Stable Amorphous IrOOH for Water Splitting.

Evaluating the structural and electronic-state characteristics of long-range disordered amorphous iridium (Ir)-based oxides is still unsatisfying. Compared with the benchmark IrO, the higher oxygen evolution reaction (OER) performance brought by IrOOH was normally considered to be associated with the pristine Ir-containing species. However, such a conclusion conflicts with the opinion that high-valence metals can create excellent OER activity.

Ultra-high adsorption of Hg using impregnated activated carbon by selenium.

Activated carbon was one of the main adsorptions utilized in elemental mercury (Hg) removal from coal combustion flue gas. However, the high cost and low physical adsorption efficiency of activated carbon injection (ACI) limited its application.

Background: Human adipose-derived stem cells (hADSCs) have been demonstrated to be a promising autologous stem cell source for treating various neuronal diseases. Our study indicated that hADSCs could be induced into neuron-like cells in a stepwise manner that are characterized by the positive expression of MAP2, SYNAPSIN 1/2, NF-200, and vGLUT and electrophysiological activity. We first primed hADSCs into neuron-like cells (hADSC-NCs) and then intracerebrally transplanted them into MCAO reperfusion mice to further explore their in vivo survival, migration, integration, fate commitment and involvement in neural circuit rebuilding.
