A dual-target electrochemical aptasensor was developed for the simultaneous detection of multiple antibiotics based on metal ions as signal tracers and nanocomposites as signal amplification strategy. Metal ions such as Cd2+ and Pb2+ could generate distinct differential pulse voltammetry (DPV) peaks. When targets were present, kanamycin (KAN) and streptomycin (STR) as models, the KAN aptamer (KAP) and STR aptamer (STP) were released from their complementary strands, with more change of Cd2+ and Pb2+ corresponding to peak currents...

Chondroitin sulfate (CS) is an important component of the extracellular matrix of cartilage and has been widely used as one of the main drugs for the treatment of joint pain-related nutraceuticals and medicines. Sturgeon bone (SB) is the main waste during deep processing of sturgeons in fishery production. The present study was evaluated the therapeutic effect of CS from SB (CSSB) on monosodium iodoacetate (MIA)-induced osteoarthritis (OA) pain and further explored the potential medicinal value of CSSB. The OA pain model was induced by intra-articular injection of MIA and then treated with CSSB...

Our previous studies demonstrated that the nonstructural NV protein of infectious hematopoietic necrosis virus (IHNV) was essential for efficient viral replication and pathogenicity, and that the amino acid residues 32 EGDL35 of the NV protein were responsible for nuclear localization, and played important roles in suppressing IFN and inhibiting NF-κB activity. However, little is known about the influence of 32 EGDL35 on IHNV replication and pathogenicity. In the present study, two recombinant IHNV strains with deletions of NV 32 EGDL35 were generated and the effect on IHNV replication and pathogenicity was explored...

Asymmetric division (ASD), the unique characteristic of normal stem cells, is regarded as a stemness marker when applied to the study of cancer stem cells (CSCs). However, the role of ASD in the self-renewal of CSCs and its regulation remain largely unknown. Here, we first established a mouse Lewis lung carcinoma CSC cell line that could undergo asymmetric division (LLC-ASD cells) derived from the parental mouse Lewis lung carcinoma cancer cells (LLC-Parental cells). In vitro assessment of stemness by RT-qPCR and western blot analysis of stem cell markers, clonogenic assay (p < 0...

The purpose of the present study was to investigate whether ɑ-tocopherol exhibited neuro-protective effects in chronic unpredictable mild stress (CUMS) mice through the regulation of autophagy. Deficits in behavioural tests, including a sucrose preference test, open field test, forced swim test, and tail suspension test, were ameliorated following ɑ-tocopherol administration. To study the potential mechanism, western blots were performed on both prefrontal cortex and hippocampus samples. Similar to the degree of autophagy, the activities of adenosine monophosphate-activated protein kinase (AMPK) and Unci-51 like autophagy activating kinase-1 (ULK1) were decreased after CUMS stimulation...

Our previous study showed that docosahexaenoic acid (DHA) plays an important role in decreasing lipid accumulation by inducing apoptosis of the adipocytes in grass carp. However, the mechanism involved remains unclear. DHA has been reported as the natural ligand of PPARγ. The present study aimed to assess whether PPARγ mediates the pro-apoptotic effects by DHA. Adipocytes of grass carp were cultured until 2 days post-confluence and were treated with DHA at various concentrations-0, 25, 50, 100, 200, and 400 μmol/L for 24 h and at 200 μmol/L for various time periods (0, 12, 24, and 48 h, respectively)...

Electron transport layers (ETLs) with suitable energy level alignment for facilitating charge carrier transport as well as electron extraction are essential for planar heterojunction perovskite solar cells (PSCs) to achieve high open-circuit voltage (VOC) and short-circuit current. Herein we systematically investigate band offset between ETL and perovskite absorber by tuning F doping level in SnO2 nanocrystal. We demonstrate that gradual substitution of F- into the SnO2 ETL can effectively reduce the band offset and result in a substantial increase in device VOC...

Incorporating narrow-bandgap near-infrared absorbers as the third component in a donor/acceptor binary blend is a new strategy to improve the power conversion efficiency (PCE) of organic photovoltaics (OPV). However, there are two main restrictions: potential charge recombination in the narrow-gap material and miscompatibility between each component. The optimized design is to employ a third component (structurally similar to the donor or acceptor) with a lowest unoccupied molecular orbital (LUMO) energy level similar to the acceptor and a highest occupied molecular orbital (HOMO) energy level similar to the donor...

Cesium lead halide (CsPbX3 ) perovskite has emerged as a promising low-threshold multicolor laser material; however, realizing wavelength-tunable lasing output from a single CsPbX3 nanostructure is still constrained by integrating different composition. Here, the direct synthesis of composition-graded CsPbBrx I3- x nanowires (NWs) is reported through vapor-phase epitaxial growth on mica. The graded composition along the NW, with an increased Br/I from the center to the ends, comes from desynchronized deposition of cesium lead halides and temperature-controlled anion-exchange reaction...

Two medium-bandgap p-type organic small molecules H21 and H22 with an alkylsily-thienyl conjugated side chain on benzo[1,2-b:4,5-b']dithiophene central units are synthesized and used as donors in all-small-molecule organic solar cells (SM-OSCs) with a narrow-bandgap n-type small molecule 2,2'-((2Z,2'Z)-((4,4,9,9-tetrahexyl-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene-2,7-diyl)bis(methanylylidene))bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (IDIC) as the acceptor. In comparison to H21 with 3-ethyl rhodanine as the terminal group, H22 with cyanoacetic acid esters as the terminal group shows blueshifted absorption, higher charge-carrier mobility and better 3D charge pathway in blend films...

There is accumulating evidence that decreased histone acetylation is involved in normal aging and neurodegenerative diseases. Recently, we found that ANP32A, a key component of INHAT (inhibitor of acetyltransferases) that suppresses histone acetylation, increased in aged and cognitively impaired C57 mice and expressing wild-type human full length tau (htau) transgenic mice. Downregulating ANP32A restored cognitive function and synaptic plasticity through upregulation of the expressions of synaptic-related proteins via increasing histone acetylation...

Tattooing is a procedure where ink is applied to an area of the skin, mostly intraepidermally (1). This procedure is carried out mainly for aesthetic purposes. Lately, it has been used as a corrective medical procedure following amputation of mammilla. The procedure is aggressive (2), and the fact that skin is punctured many times with the same needle which cannot be fully sterilized may cause infection of the treated area with bacterial, fungal, or viral agents that may lead to health consequences manifesting in the form of verrucae vulgaris, molluscum contagiosum, and herpes simplex...

Worldwide melanoma incidence and mortality are increasing (1). Despite the ongoing research, advanced melanoma is still incurable; therefore, the most appropriate solution seems to be early detection combined with complete surgical excision (2). Since the diagnostic protocol of suspicious lesions includes a complete excision with safety margins (2), the problem of unnecessary scarring is significant. The real challenge in this case is to have a properly formulated diagnosis before acquiring a biopsy. Currently available non-invasive techniques are coherence tomography, digital dermoscopy, and reflectance confocal microscopy...

Drug-induced lupus erythematosus (DI-LE) is an autoimmune condition secondary to a recent pharmacological intervention. There are no established specific diagnostic criteria for DI-LE, and the disease is recognized based on the medical history of the patient. Typically, the onset is closely related to a recent drug exposure, and the disease terminates after discontinuation of the inducing factor. The most frequent form of DI-LE is drug-induced subacute cutaneous lupus erythematosus (DI-SCLE). There has been an increasing number of drugs which are suspected to provoke SCLE lesions...

We investigated the beneficial effects of midazolam against vascular endothelial growth factor (VEGF)-induced vascular leakage and its molecular mechanism of action in human retinal endothelial cells (HRECs) and the retinas of diabetic mice. Midazolam inhibited VEGF-induced elevation of intracellular Ca2+ , generation of reactive oxygen species (ROS), and transglutaminase activation in HRECs; these effects were reversed by the GABA, type A (GABAA ) receptor antagonist flumazenil but not by the translocator protein antagonist PK11195...

Mesenchymal stem cells (MSCs) were regarded as one of the most promising type of seed cells in tissue engineering due to its easy accessibility and multipotent feature of being able to differentiate into adipocyte, osteoblast, cardiomyocytes, and neurons. For years, MSCs have been applied in treating cardiovascular disease, reconstructing kidney injury, and remodeling immune system with remarkable achievements. Basic researches revealed that its clinic effects are not only due to their pluripotent ability but also through their paracrine function that they synthesize and secrete a broad spectrum of growth factors and cytokines...

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) with layered structures provide a unique platform for exploring the effect of number of layers on their fundamental properties. However, the thickness scaling effect on the chemical properties of these materials remains unexplored. Here we explored the chemically induced phase transition of 2D molybdenum disulfide (MoS2) from both experimental and theoretical aspects and observed that the critical electron injection concentration required for the phase transition of 2D MoS2 increased with decreasing number of layers...
