In this work, we have developed multiple-armed DNA tetrahedral nanostructures (TDNs) for dual-modality in vivo imaging using near-infrared (NIR) fluorescence and single-photon emission computed tomography (SPECT). We found that the presence of arm strands TDNs remarkably enhanced their vitro stability, allowing them to stay intact at least 12 h serum. By NIR imaging, evaluated mice pharmacokinetics TDNs, which exhibited distinctly different biodistribution patterns compared with those...
The gingival epithelium-capillary interface is a unique feature of periodontal soft tissue, preserving tissue homeostasis and preventing microorganism toxic substances from entering the subepithelial tissue. However, function disturbed in periodontitis, mechanisms breakdown are incompletely understood. To address these limitations, we developed microfluidic barrier with thin culture membrane (10 μm) that closely mimics vivo epithelial an immune micro-environment. test validity fabricated...
40 Hz light flicker is a well-known non-invasive treatment that thought to be effective in treating Alzheimer's disease. However, the effects of visual stimulation on neural networks, synaptic plasticity, and learning memory wild-type animals remain unclear.We aimed explore impact place cell, mice.c-Fos+ cell distribution vivo electrophysiology was used chronic networks neuroplasticity mice. The character c-Fos+ brain changes corticosterone levels blood were investigate state animal. Place...
Cocaine, the archetypal tropane alkaloid from plant genus Erythroxylum, has recently been used clinically as a topical anesthesia of mucous membranes. Despite this, key biosynthetic step requisite skeleton (methylecgonone) identified intermediate 4-(1-methyl-2-pyrrolidinyl)-3-oxobutanoic acid (MPOA) remained, until this point, unknown. Herein, we identify two missing enzymes (EnCYP81AN15 and EnMT4) necessary for biosynthesis in cocaine by transient expression candidate genes Nicotiana...
Abstract Tropane alkaloids such as hyoscyamine and cocaine are of importance in medicinal uses. Only recently has the biosynthetic machinery become complete. However, biosynthesis pathway remains only partially elucidated. Here we characterize polyketide synthases required for generating 3-oxo-glutaric acid from malonyl-CoA route. Structural analysis shows that these two adopt distinctly different active site architecture to catalyze same reaction pyrrolidine ketide synthase biosynthesis,...
Montane small mammals are subjected to strong forces of dispersal limitation and habitat filtering that mainly operate on their community structures along the altitudinal direction. However, so far little is known about relative contributions niche processes assembly. By applying newly proposed PER‐SIMPER/DNCI (dispersal–niche continuum index) framework mammal occurrence data collected from 21 extensive gradients, we quantitatively assessed importance mammalian assembly in a large...
An electronic current transformer with a B-dot sensor is proposed in this study. The can realize the measurement of transmission line non-contact way accordance principle magnetic field coupling. multiple electrodes series-opposing structure applied together differential input structures and active integrating circuits, which allow to operate mode. Maxwell software adopted model simulate sensor. Optimization structural parameters conducted through finite-element simulation. A test platform...
When the transformer is running, vibration which generated in core and winding will spread outward through medium of metal, oil, air. The magnetic field changes with variation excitation source state core, so corresponding noise change. Therefore, contain a lot information. If information can be associated fault characteristics transformer, it significant to evaluate running signal, improve intelligence, safety, stability operation. Based on this, modeling simulation multi-point grounding,...
A 61-kb biosynthetic gene cluster (BGC), which is accountable for the biosynthesis of hibarimicin (HBM) B from Microbispora rosea subsp. hibaria TP-A0121, was heterologously expressed in Streptomyces coelicolor M1154, generated a trace target products but accumulated large amount shunt products. Based on rational analysis relevant secondary metabolism, directed engineering pathways resulted high production HBM B, as well new derivates with improved antitumor activity. These results not only...

We propose a new highly reliable and lightweight embedded optical torque sensor for biomimetic robot arm enabling the measurement in joints, which can measure of joint by detecting torsion its elastic element (mechanical structure or flexure element). Flexure spring is introduced as this paper. Because curve modeling, not inclined to be broken contrast crossbeam structure, commonly used sensor. Thanks we build an extremely compact size. Six types are proposed paper, have potential...
Dissolved gas analysis (DGA) is a common technology used in the on-site maintenance of oil-immersed power transformers industry at present. However, when content dissolved oil reaches attention value DGA method can effectively diagnose operating state transformer. Due to lack production data free which was detected faults occur, cannot timely transformer status. To solve above problem, an experimental platform built for studying generation law under discharge faults, and characteristic...
Magnetic lead screw (MLS) owns many merits for wave energy generation system applications. However, to resist the huge, instantaneous impact of waves, radius mover and rotor MLS should be large obtain sufficient stiffness. And length needs match height transfer as much power possible. Therefore, a great permanent magnets (PMs) will consumed when size traditional is maximum thrust force would greater than excitation force. This waste PMs poor starting performance. Also, ideal spiral are quite...
