Perovskite nanocrystal superlattices: self-assembly, collective behavior, and applications.

Metal halide perovskite nanocrystals (NCs) have been widely studied for application in photonics and optoelectronics due to their excellent photoelectric properties. Perovskite NCs with narrow luminescence linewidth and high photoluminescence quantum yield are excellent assembly modules for building large-scale NC superlattices. The coupling of optics and electricity in such excellent aggregates gives them exceptional collective photoelectric performance, such as superfluorescence, red-shifted emission, coupling-enhanced electron transport, Perovskite NC superlattices are expected to become another hot research topic in optoelectronics.

Bas-relief modeling from RGB monocular images with regional division characteristics.

Traditional Bas-relief modeling methods are often limited to inefficient and difficult to be altered after the product is formed. This paper presents a novel method for bas-relief modeling from RGB monocular images with regional division characteristics. The problem discussed in this paper involves edge detection, region division, height value recovery and three-dimensional reconstruction of image.

[Short-term memory characteristics of vibro-tactile perception in human fingertips].

This paper discusses the short-term memory of vibro-tactile perception of human fingertips. By using a self-developed vibro-tactile expression device, a recall experiment was firstly carried out among 20 subjects aged 20-30 (10 males and 10 females) to discover the memory span about the vibro-tactile perception of human fingertips. Within this memory span, a cognitive experiment analyzing the recognition accuracy and the reaction time was carried out.

Aβ monomer induces phosphorylation of Tau at Ser-214 through β2AR-PKA-JNK signaling pathway.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder associated with synaptic dysfunction, pathological accumulation of β-amyloid peptide 1-42 (Aβ ), and neuronal loss. The self-association of Aβ monomers (Aβ-M) into soluble oligomers seems to be crucial for the development of neurotoxicity. Previous publications have shown that Aβ oligomers and dimers might play key roles in inducing AD.

Mixture of five herbal extracts ameliorates pioglitazone-induced aggravation of hepatic steatosis via activating the adiponectin receptor 2/AMP-activated protein kinase signal pathway in diabetic KKAy mice.

Objective: To assess the effect of a mixture of five herbal extracts (FT-5) on insulin resistance, glucose/lipid metabolism, hepatic steatosis, and to investigate whether the combination of FT-5 and pioglitazone would provide a robust effect on diabetes treatment, while may minimize undesirable side-effects of pioglitazone in diabetic Ay gene (KKAy) mice.

Methods: Seven-week-old KKAy mice were randomly divided into five groups: control (CON) group, FT-5 (2.0 g/kg) group, pioglitazone (20 mg/kg) (PIO) group, pioglitazone (20 mg/kg) + FT-5 (2.

Tangnaikang improves insulin resistance and β-cell apoptosis by ameliorating metabolic inflammation in SHR.Cg-Leprcp/NDmcr rats.

Objective: To investigate the effects of Tangnaikang (TNK), a mixture of five herbal plant extracts, on inflammation-mediated insulin resistance and B-cell apoptosis in SHR.Cg-Leprcp/NDmcr (SHR-cp) rats.

Methods: Seven-week-old SHR-cp rats were randomly divided into a control (CON) group and a TNK (3.

[Synergism inhibition of curcumin combined with cisplatin on T24 bladder carcinoma cells and its related mechanism].

Objective: To investigate the synergism inhibition of curcumin combined with cisplatin on T24 bladder carcinoma cells and the down-regulating effect of curcumin on the Keapl-Nrf2 pathway, a well recognized anti-drug pathway in almost drugged tumor cells.

Methods: T24 cells were cultured and treated with increasing concentrations of curcumin(5 ,10 and 20 µmol/mL) combined with cisplatin(30 µg/mL) for 24 hours. The inhibitory effects on T24 cells were tested with MTI colorimetric assay.

Qiwei granules alleviates podocyte lesion in kidney of diabetic KK-Ay mice.

Background: Chinese medicine comprised of all natural herbs is widespread used in the treatment of diabetic nephropathy (DN). Podocyte contributes to the integrity of glomerular filtration barrier whose injury plays an important role in the initiation and progression of DN. Our study aimed to investigate the effect of Qiwei granules on podocyte lesion in diabetic KK-A(y) mice kidney and its underlying mechanism.

Tang-Nai-Kang alleviates pre-diabetes and metabolic disorders and induces a gene expression switch toward fatty acid oxidation in SHR.Cg-Leprcp/NDmcr rats.

Increased energy intake and reduced physical activity can lead to obesity, diabetes and metabolic syndrome. Transcriptional modulation of metabolic networks has become a focus of current drug discovery research into the prevention and treatment of metabolic disorders associated with energy surplus and obesity. Tang-Nai-Kang (TNK), a mixture of five herbal plant extracts, has been shown to improve abnormal glucose metabolism in patients with pre-diabetes.
