Vanadium as a Ti-like mediator boosting electronic transmission in Fe-based MOFs for photocatalytic sterilization.

Efficient metal-organic frameworks (MOFs) photocatalytic bactericidal catalysts are urgently needed in water purification. Herein, a Fe-MOF (MIL-88B-NH(VFe) with promoted electron transport was achieved by vanadium (V) ions doping and V/Fe ratio optimization, showing excellent photocatalytic bactericidal activity againstunder visible light irradiation (99.92%).

Engineering valence-mismatched Ti into Fe-based metal-organic-frameworks for enhanced photocatalytic CO reduction.

A series of low-dose high-valence Ti doped MIL-53-NH(Fe) photocatalysts were synthesized for visible-light-driven CO reduction. The highest CO-to-CO conversion rate of Ti doped MIL-53-NH(Fe) was 7.24 mmol g h and the highest CO selectivity was 94% in acetonitrile solvent using [Ru(bpy)] and triethanolamine.

NALA: a Nesterov accelerated look-ahead optimizer for deep learning.

Adaptive gradient algorithms have been successfully used in deep learning. Previous work reveals that adaptive gradient algorithms mainly borrow the moving average idea of heavy ball acceleration to estimate the first- and second-order moments of the gradient for accelerating convergence. However, Nesterov acceleration which uses the gradient at extrapolation point can achieve a faster convergence speed than heavy ball acceleration in theory.

A case report of recurrent leiomyosarcoma with chondrosarcoma differentiation in the abdominal wall and a review of the literature.

Leiomyosarcoma with heterologous differentiation is relatively rare. To date, only 19 cases have been reported in the English literature. Heterologous components frequently show histological pleomorphism, while those exhibiting well-differentiated morphology are seldom reported.

Assessing the chronic hepatitis B adaptive immune response by profiling specific T-cell receptor repertoire.

Challenges in assessing hepatitis B virus (HBV)-specific T cell immunity as an immunological biomarker still remain in chronic hepatitis B (CHB), such as the requirement of large quantities of cells. This study aims to conveniently assess HBV-specific T cells immunity in chronic HBV infected patients. We obtained T cell receptor β chains (TCRβs) from public databases and six acute hepatitis B patients to establish an HBV-specific TCRβs dataset.

Case report: cotyledonoid dissecting leiomyoma in a 49-year-old woman.

Background: Cotyledonoid dissecting leiomyoma (CDL) is much less common than typical leiomyoma. Macroscopically, it displays multinodular, exophytic, placenta-like cystic masses and extends into the broad ligament, pelvic cavity, and retroperitoneal space. The seemingly malignant gross appearance of the tumor has perplexed gynecologists and pathologists; microscopically, it has no malignant characteristics, such as atypical cells, a high mitotic index, or tumor necrosis.

The Effect and Mechanism of Curcumin Combined with Carboplatin Chemotherapy Promoting on Apoptosis of Lung Cancer HCC827 Cells.

Objective: To investigate the effect and mechanism of curcumin (CUR) killing lung cancer HCC827 cell spheres.

Method: HCC827 cell spheres were cultured in serum-free medium, and the protein expression of CD133, SOX2, EpCAM, and ABCG2 was detected by western blot. MTT was used to evaluate the cell viability of HCC827 cell spheres and HCC827 cell after they were treated by 1, 2, 5, 10, and 20 mg/mL carboplatin (CBP) for 48 h.

Stacked Dual-Band Quantum Well Infrared Photodetector Based on Double-Layer Gold Disk Enhanced Local Light Field.

We propose a stacked dual-band quantum well infrared photodetector (QWIP) integrated with a double-layer gold disk. Two 10-period quantum wells (QW) operating at different wavelengths are stacked together, and gold nano-disks are integrated on their respective surfaces. Numerical calculations by finite difference time domain (FDTD) showed that the best enhancement can be achieved at 13.

[Estimating the climatic capacity of food security in Henan Province, China under the future climate change scenarios].

To explore the effects of future climate change on food production in Henan Province, the climate potential productivity and its change characteristics in Henan Province were calculated by agro-ecological zone (AEZ) model. This study was based on the production potential and climate resource carrying capacity of summer maize and winter wheat, combined with the observation data of 111 meteorological stations in Henan Province from 1961 to 2017 and the meteorological data under two emission scenarios of RCP4.5 and RCP8.

Rutaecarpine derivative R3 attenuates atherosclerosis via inhibiting NLRP3 inflammasome-related inflammation and modulating cholesterol transport.

Atherosclerosis is a chronic disease characterized by lipid deposition and inflammatory response. NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome-facilitated inflammatory responses are crucial in the pathogenesis of atherosclerosis, and thus new therapeutic approaches are emerging that target NLRP3 and inflammation. Here, we explored the anti-atherosclerotic effect and mechanisms of a new rutaecarpine derivative, 5-deoxy-rutaecarpine (R3) in vitro and in vivo.

Identification of autoimmune type 1 diabetes and multiple organ-specific autoantibodies in adult-onset non-insulin-requiring diabetes in China: A population-based multicentre nationwide survey.

Aims: To investigate the prevalence of adult-onset autoimmune diabetes (ADM) and predisposition to autoimmune diseases by quantifying serum organ-specific autoantibodies in people with phenotype of type 2 diabetes (T2D).

Materials And Methods: We included a nationally representative sample of 46 239 adults aged ≥20 years from 14 provinces, of whom 4671 had diabetes, plus 1000 control subjects with normal glucose tolerance (NGT). Participants were screened centrally for autoantibodies to glutamic acid decarboxylase (GAD), islet antigen 2 (IA2) and zinc transporter isoform-8 (Znt8) and were defined as having ADM where positive for these antibodies.

Combined use of bFGF/EGF and all-trans-retinoic acid cooperatively promotes neuronal differentiation and neurite outgrowth in neural stem cells.

Neural stem cells (NSCs) as sources of new neurons in brain injuries or diseases are required to not only elicit neurons for neuronal repair, but also to enhance neurite outgrowth for neuronal network reestablishment. Various trophic or chemotropic factors have been shown to cooperatively improve NSC neurogenesis. However, effects of combined treatment of all-trans-retinoic acid (RA) with GF (Basic fibroblast growth factor and epidermal growth factor, bFGF/EGF) on neurogenesis of NSCs are poorly understood.

E3317 promotes cholesterol efflux in macrophage cells via enhancing ABCA1 expression.

Reverse cholesterol transport (RCT) plays an important role in cholesterol and lipid metabolism. Regulating the activities of key transporters and receptors in RCT, such as ATP-binding cassette transporter A1 (ABCA1), helps to prevent atherosclerotic cardiovascular disease. In this study, we used an ABCA1 promoter luciferase reporter assay to screen 20,000 compounds for ABCA1 upregulators.

SIRT1 activator E1231 protects from experimental atherosclerosis and lowers plasma cholesterol and triglycerides by enhancing ABCA1 expression.

Background And Aims: Sirtuin 1 (SIRT1) is a nicotinamide adenine dinucleotide-dependent protein deacetylase. Recent studies have demonstrated that enhancing SIRT1 expression or activity may modulate cholesterol and lipid metabolism. However, pharmacological and molecular regulators for SIRT1 are scarce.

A novel SIRT1 activator E6155 improves insulin sensitivity in type 2 diabetic KKA mice.

Sirtuin 1 (SIRT1) is an NAD-dependent protein deacetylase that plays a critical role in controlling energy metabolism, stress response and aging. Hence, enhancing SIRT1 activity could be a potential therapeutic strategy to treat metabolic diseases such as diabetes. However, pharmacological activators for SIRT1 are scarce to date.

Cross-section control of stacked nanowires formed by Bosch process and oxidation.

The cross-sectional shape of the stacked silicon nanowires (SiNWs) formed by the Bosch process and stress-limited oxidation is studied in this paper. Under the condition of high temperature oxidation, the resulting nanowires highly resemble the initial shapes resulting by the Bosch process. The effects of etching and passivation in the Bosch process are modeled to provide a guideline to control the cross-section of the stacked nanowires.
