D30 Alleviates β2-Microglobulin-Facilitated Neurotoxic Microglial Responses in Isoflurane/Surgery-Induced Cognitive Dysfunction in Aged Mice.

Postoperative cognitive dysfunction (POCD) is a common complication with no effective treatment in elderly patients. POCD, Alzheimer disease (AD), and many other cognitive diseases mostly involve neurotoxic microglia response, and recently, β2-microglobulin (B2M) has been suggested to play a pivotal role. A novel pyromeconic acid-styrene hybrid compound D30 was synthesized by our team and shown to be safe and effective in some neurodegenerative mouse models.

Identification of a family with van der Hoeve's syndrome harboring a novel COL1A1 mutation and generation of patient-derived iPSC lines and CRISPR/Cas9-corrected isogenic iPSCs.

Van der Hoeve's syndrome, also known as osteogenesis imperfecta (OI), is a genetic connective tissue disorder characterized by fragile, fracture-prone bone and hearing loss. The disease is caused by a gene mutation in one of the two type I collagen genes COL1A1 or COL1A2. In this study, we identified a novel frameshift mutation of the COL1A1 gene (c.

PAX3 mutation suppress otic progenitors proliferation and induce apoptosis by inhibiting WNT1/β-catenin signaling pathway in WS1 patient iPSC-derived inner ear organoids.

Waardenburg syndrome type 1 (WS1) is a hereditary disease mainly characterized by sensorineural hearing loss, dystopia canthorum, and pigmentary defects. To elucidate molecular mechanisms underlying PAX3-associated hearing loss, we developed inner ear organoids model using induced pluripotent stem cells (iPSCs) derived from WS1 patient and healthy individual. Our results revealed a significant reduction in the size of inner ear organoids, accompanied by an increased level of apoptosis in organoids derived from WS1 patient-iPSCs carrying PAX3 c.

Establishment of two iPSC lines from healthy donor with heterozygous mutation in the SLC26A4 gene.

The human induced pluripotent stem cell (iPSC) lines, CSUXHEi001-A and CSUXHEi002-A, were generated from peripheral blood mononuclear cells (PBMCs). The donors were couple and each of them has a heterozygous mutation in the SLC26A4 gene. It manifests in their children as Enlarged vestibular aqueduct (EVA).

Activation of metabotropic glutamate receptor 1 regulates hippocampal CA1 region excitability in rats with status epilepticus by suppressing the HCN1 channel.

Dysregulation of hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels alters neuronal excitability. However, the role of HCN channels in status epilepticus is not fully understood. In this study, we established rat models of pentylenetetrazole-induced status epilepticus.

Metal-Organic Frameworks Functionalized Separators for Lithium-Sulfur Batteries.

Lithium sulfur batteries (LSBs) have attracted tremendous attention owing to their high theoretical specific capacity and specific energy. However, their practical applications are hindered by poor cyclic life, mainly caused by polysulfide shuttling. The development of advanced materials to mitigate the polysulfide shuttling effect is urgently demanded.

Two-Dimensional Metal-Organic Framework Nanosheets: Synthesis and Applications in Electrocatalysis and Photocatalysis.

Two-dimensional metal-organic nanosheets (2D MONs) are an emerging class of ultrathin, porous, and crystalline materials. The organic/inorganic hybrid nature offers MONs distinct advantages over other inorganic nanosheets in terms of diversity of organic ligands and metal notes. Compared to bulk three-dimensional metal-organic frameworks, 2D MONs possess merits of high density and readily accessible catalytic sites, reduced diffusion pathways for reactants/products, and fast electron transport.

Objective: To construct a recombinant lentiviral vector containing integrin β1 shRNA to provide an effective tool for integrin β1 gene effect and a possible mechanism of Sombati cell of clinical refractory epilepsy.

Methods: Four lentiviral vectors containing integrin β1 shRNA were constructed and transfected into 293T cells. PC12 cells were infected by concentrated lentivirus and the gene-silencing efficiency was verified.

[In vivo reflectance spectroscopy study of different clearing agents on human skin optical clearing].

The changes of skin tissue reflectance spectroscopy before and after being treated with the optical clearing agents of three different types of optical clearing within the wavelength rang of 400-1 000 nm, and the degree of changes in reflectance spectroscopy of each group skin during 0-60 min at 580 nm in vivo were real-time dynamically researched. The reflectance spectroscopy of skin tissue before and after being dealt by the optical clearing agents of glycerol, glucose and propylene glycol was measured using a USB-4000 fiber spectrophotometer at 0, 10, 20, 30, 40, 50 and 60 min. The results showed that the reflectance spectral intensity was distinctly decreased, but the reflectance was significantly increased gradually with the time prolonged.

Expression and clinical significance of syndecan-1 mRNA and HPA-1 mRNA in colorectal cancer detected with real-time fluorescent quantitative polymerase chain reaction.

Background And Objective: Invasion and metastasis are the most common causes of mortality for patients with colorectal neoplasms, and blocking invasion and metastasis in a timely fashion has become a hot research focus. We investigated the expression of the messenger RNA of Syndecan-1 and HPA-1 in colorectal cancer, and their correlation with invasion and metastasis.

Methods: Real-time fluorescent quantitative polymerase chain reaction (PCR) was used to detect the expression of Syndecan-1 and HPA-1 in specimens from 49 patients with colorectal cancer, 49 paired adjacent colorectal neoplasms (2 cm from the carcinoma), and 49 surgical margins of paired normal colorectal mucosa tissue (5 cm from the carcinoma), to analyze their correlation with clinicopathologic characteristics of colorectal neoplasm.

Objective: To evaluate the adjuvant effect of transcutaneous electrical acupoint stimulation (TEAS) in propofol-fentanyl anesthesia in partial mastectomy.

Methods: Ninety patients undergoing partial mastectomy were randomly divided into 3 groups (n=30), namely group A with propofol-fentanyl anesthesia (PFVA), group B with PFVA and TEAS at Hegu-Laogong and Neiguan-WaiGuan acupoints, and group C with PFVA and TEAS at Hegu-Laogong, Neiguan-Waiguan, and bilateral Jianjing acupoints. The bispectral index (BIS), heart rate (HR), saturation of pulse oxygen (SpO2), blood pressure (BP), the reaction of patients to the incision and awakening quality were observed at different time points.
