Efficient Dlx2-mediated astrocyte-to-neuron conversion and inhibition of neuroinflammation by NeuroD1.

In vivo astrocyte-to-neuron (AtN) conversion induced by overexpression of neural transcriptional factors has great potential for neural regeneration and repair. Here, we demonstrate that a single neural transcriptional factor, Dlx2, converts mouse striatal astrocytes into neurons in a dose-dependent manner. Lineage-tracing studies in Aldh1l1-CreERT2 mice confirm that Dlx2 can convert striatal astrocytes into DARPP32 and Ctip2 medium spiny neurons (MSNs).

[Difficulties and Confusion Concerning the Management of Hypertensive Disorders in Pregnancy--Interpretation of the Guidelines for the Diagnosis and Treatment of Hypertensive Disorders in Pregnancy (2020)].

Hypertensive disorder in pregnancy is a disease with diverse clinical manifestations. Herein, we provided interpretations for "The Guidelines for the Diagnosis and Treatment of Hypertensive Disorders in Pregnancy in China (2020 Edition)" and discussed the difficulties and confusion encountered in the management of hypertensive disorders in pregnancy in combination with clinical practice. Lowering blood pressure is the most important treatment and maintaining a stable target blood pressure can reduce damage to organ functions and is beneficial to fetal growth.

Copy Number Analyses Identified a Novel Gene: Related to Lipid Metabolism in the Pathogenesis of Preeclampsia.

Background: Preeclampsia is a heterogeneous and complex disease with its pathogenesis mechanism not fully elucidated. A certain subset of patients with preeclampsia exhibit disturbances in lipid metabolism before clinical symptoms. Moreover, there is a tendency for preeclampsia to run in families.

Guideline for Quality Control of Powered Polymerisation Activators for Chairside Use.

The irradiance of powered polymerisation activators for chairside use affects composite resin adhesive curing during the restorative process, whereas radiant accumulated temperature rise relates to clinical safety. Irradiance reduction and high radiant accumulated temperature will compromise the treatment results as there is a lack of curing output efficacy and safety awareness for powered polymerisation activators. Insufficient attention has been paid to the activator's quality control, irradiance attenuation and radiant accumulated temperature excessive temperature rise during its lifetime.

Pathogenic Detection by Metagenomic Next-Generation Sequencing in Osteoarticular Infections.

To evaluate metagenomic next-generation sequencing (mNGS) as a diagnostic tool in detecting pathogens from osteoarticular infection (OAI) samples. 130 samples of joint fluid, sonicate fluid, and tissue were prospectively collected from 92 patients with OAI. The performance of mNGS and microbiology culture was compared pairwise.

Prognostic role of the recepteur d'origine nantais (RON) expression in primary high-grade osteosarcoma.

Background: Osteosarcoma is a common primary malignant bone tumor susceptible to distant metastasis. The clinical outcome for patients remains poor due to the resistance to chemotherapy and lacking effective therapeutic targets. Recepteur d'origine nantais (RON), a transmembrane protein of the c-MET proto-oncogene family, has been reported to contribute to the malignant progression and bone metastasis in several tumors.

Guideline for Limb-Salvage Treatment of Osteosarcoma.

Osteosarcoma is the most common primary malignant bone tumor, occurring mainly in children and adolescents, and the limbs are the main affected sites. At present, limb-salvage treatment is considered as an effective basic standard treatment for osteosarcoma of the limb. China has a vast territory, but the development of technology is not balanced,which requires sufficient theoretical coverage, strong technical guidance and the application of limb-salvage treatment guidelines to the treatment of osteosarcoma.

Clinicopathological and prognostic value of NADPH oxidase 2 (NOX2) in primary osteosarcoma.

Background: Osteosarcoma is the most common primary malignant bone tumor, particularly among children and adolescents, and the prognosis of osteosarcoma patients remains poor. The NADPH oxidase 2 (NOX2) has been found over-expressed in several human cancers, and closely associated with poor prognosis. Meanwhile the role of NOX2 in osteosarcoma patients has not been reported.

Clinicopathological value of ErbB2 gene and protein expression in osteochondroma.

Objective: The aim of this study was to investigate ErbB2 expression in osteochondroma and its relationship with clinicopathologic features of osteochondroma, so as to identify a new biomarker for the malignant transformation potential of osteochondroma.

Methods: Immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) were used to investigate the expression status of ErbB2 protein and gene in 30 osteochondroma tissues and 20 non-neoplastic bone tissues. The association of ErbB2 gene and protein expression with clinicopathological parameters of osteochondroma was analyzed by using the χ2 test and Fishers exact test.

Initial-onset symptoms of preeclampsia and their relation to pregnancy outcomes.

Preeclampsia (PE) is a serious gestational idiopathic hypertensive disease, threatening both maternal and foetal safety. As a systemic disease, the initial-onset symptoms (IOSs) and clinical manifestations of PE can vary widely from patient to patient. However, a lack of evidence-based data on IOS and their relationship to their corresponding clinical features and pregnancy outcomes persists.

Background: Osteosarcoma is a malignant bone tumor with a high potential for lung metastasis, and the prognosis for patients with metastatic disease is very poor. The interaction between fibronectin (FN) and integrin αvβ3 in soft-tissue sarcoma promotes cell migration, invasion, and lung metastasis. This study aimed to investigate the prognostic significance of FN and αvβ3 in osteosarcoma.

MicroRNA-885-5p promotes osteosarcoma proliferation and migration by downregulation of cell division cycle protein 73 homolog expression.

Osteosarcoma (OS) is the most common primary malignant bone tumor. Numerous studies have strongly implicated the ectopic expression of microRNAs (miRNAs/miRs), including miR-885-5p, which is aberrantly expressed in several cancer types, in multiple cancer-related processes. However, the role of miR-885-5p in OS remains unknown.

Coordination polymer-based supercapacitors with matched energy levels: enhanced capacity under visible light illumination in the presence of methanol.

Using 4-[5-(1H-pyrazol-4-yl)-4H-[1,2,4]triazol-3-yl]-pyridine (L1) and 2-(3-carboxypyridin-2-yl) nicotinic acid (H2L2), two coordination polymers (CPs) formulated as [Cu(HL1)2(Mo8O26)]·5H2O (1) and [{Cu4(L2)4(H2O)6}(H3PMo12O40)]·7H2O (2) were hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. The two CPs exhibit a 2D architecture, but strong interlayer π-π stacking interactions are only observed in the structure of CP 1. Diffuse reflectance spectroscopy (DRS) and DFT calculations reveal that CP 1 is a semiconductor with a narrow band gap of 1.
