Prodrug, in which the inactive parent drug with good bioavailability is metabolized into an active body, one of main strategies to target disease site improve efficiency and reduce adverse effects chemotherapy. Because capability chemical modification, zein, a plant derived protein, drugs can be conjugated through environmentally sensitive links form prodrugs capable triggered release. In this study, novel prodrug was synthesized using paclitaxel (PTX), disulfide linker, nanoparticles were...
This study presents a novel and highly accurate method of measuring the geometric thickness self-lubricating fabric liner bearings by combining optical coherence tomography (OCT) technology Hanning-windowed energy centrobaric (HnWECM). The wear-resistant coating material is one important indicators for evaluating its wear, measurement great significance preventing failure. To address issue significant errors caused using refractive index sample instead group to calculate material’s...
Background: There is an urgent need to develop a non-invasive imaging technique for detecting colorectal dysplasia and cancer. Technology early real-time microscopic assessments select the most representative biopsy sites would also be of clinical value. In this study, we explored sensitivity optical coherence tomography (OCT) in local lesions demonstrate its potential detection Methods: An azoxymethane/dextran sodium sulfate mouse model carcinogenesis was utilized. Mice were imaged by OCT,...
To achieve pest elimination on leaves with laser power, it is essential to locate the strike point accurately. In this paper, Pieris rapae (L.) (Lepidoptera: Pieridae), similar in color host plant, was taken as object and method for identifying locating target researched. A binocular camera unit an optical filter of 850 nm wavelength designed capture image. The segmentation pests’ pixel area performed based Mask R-CNN. points were located by extracting skeleton through improved ZS thinning...
We proposed a high-performance optical coherence velocimeter (OCV) based on broadband interference which achieves spatial resolution from cancellation or enhancement of different components the light. There is challengeable issue for OCV that fringes become blurred when velocity detected object relatively large, hindering pace application in high-velocity field. To resolve this, relationship between blurry coefficient and system parameters (e.g., exposure time, central wavelength, bandwidth...
An acoustic-excitation optical coherence vibrometer (AE-OCV) is proposed for noncontact microstructure vibration measurement and modal analysis. The dynamic parameters of the can be captured with a subnanometer displacement resolution by AE-OCV using spectral wavelength calibration algorithm center correction method. natural frequency could also obtained developed system swept-frequency acoustic excitation Furthermore, home-made spectrometer based on high-speed linear camera provide range...
There is an urgent need to develop a noninvasive imaging technique for the diagnosis of early inflammatory lesions or and real-time microscopic assessment before selecting most representative biopsy sites.In this study, dextran sulfate sodium colitis model was developed, intestinal histological damage scores measured degree inflammation in colitis. According these scores, 6 parameters were designed hematoxylin eosin (HE) sections based on morphological changes, 2 optical coherence tomography...
At present, chemical pesticides remain the main approach for controlling Pieris rapae (L.) (Lepidoptera: Pieridae). This research proposes a novel laser irradiation method managing P. larvae as an alternative to control. The effectiveness of and influencing factors lasers were studied estimate optimal parameter combinations. Tests using antifeedant effect mortality dependent variables showed that power, area, opening time position positively correlated with effect. parameters each factor...
In order to achieve a better complex conjugate artifacts (CCA) suppression, we propose five-frame variable phase-shifting (FVP) method for spectral domain optical coherence tomography (SD-OCT). The traditional invariant (FIP) employs five phase shifts correlate with the center wavelength. However, due effects of polychromatic errors, FIP cannot get excellent CCA suppression. present work, employ FVP using which is dependent on all wavelengths and therefore, theoretically, system would have...
Optical coherence vibrometer (OCV) is an optical vibration measurement technology which presents the advantages of noncontact, high precision, and large dynamic range. The OCV equipment related theories are proposed to avoid excessive demands in monochromaticity stability laser source. performance Doppler (LDV) complemented by with low cost. In order obtain range (i.e., from nanometer scale centimeter scale), differential effect multiwavelength components used break phase limit interference....
