Moreover, by using liquid chromatography-mass spectrometry analysis, we demonstrate that iso-anchorene is a natural Arabidopsis metabolite. Chemical inhibition of carotenoid biosynthesis led to a significant decrease in the iso-anchorene level, indicating that it originates from this metabolic pathway. Taken together, our results reveal a novel carotenoid-derived regulatory metabolite with a specific biological function that affects root growth, manifesting the biological importance of diapocarotenoids.
In recent years, surgeons have explored minimally invasive methods of percutaneous pedicle screw implantation which can effectively reduce human injuries. This article presents an accurate and efficient positioning method and robot system for percutaneous needle placement under c-arm fluoroscopy.
A simple five degree of freedom (DOF) robot with a unique end-effector is designed to perform perspective calibration and image space registration. The principle of pedicle standard axis positioning is adopted to make the axis of the pedicle overlap with the x-ray axis of c-arm.
Then the clinical operation is carried out to verify the clinical feasibility of the designed robot and positioning method. The experimental results show that a total of 26 pedicle screws were accurately implanted. The accuracy of Grade A is 96.15%. The positioning time of a single guide pin is about 154.77s, and three x-ray films need to be taken on average.
The positioning accuracy is increased by using the present method. In addition, this method is simple in operation, short in operation time, low in X-ray exposure.

Nevertheless, the function and underlying mechanism of LINC01123 in osteosarcoma (OS) remain unclear. This study aimed to explore the roles and mechanisms of LINC01123 in OS progression. In this study, the expression of LINC01123 was significantly upregulated in OS cell lines than in a human osteoblast cell line. Furthermore, in vitro and in vivo experiments confirmed that knockdown of LINC01123 suppressed cell progression. Mechanistically, LINC01123 acted as a competing endogenous RNA by sponging miR-516b-5p, thus, increasing Gli1 expression by directly targeting its 3'UTR. Taken together, LINC01123 enhances OS proliferation and metastasis via the miR-516b-5p/Gli1 axis. Selpercatinib inhibitor Therefore, LINC01123 may be a potential therapeutic target for OS treatment.Despite increasing awareness of the biological impacts of long-chain fatty acyl-CoA esters (LCACoAs), our knowledge about the subcellular distribution and regulatory functions of these acyl-CoA molecules is limited by a lack of methods for detecting LCACoAs in living cells. Here, we report development of a genetically encoded fluorescent sensor that enables ratiometric quantification of LCACoAs in living cells and subcellular compartments. We demonstrate how this FadR-cpYFP fusion "LACSer sensor" undergoes LCACoA-induced conformational changes reflected in easily detectable fluorescence responses, and show proof-of-concept for real-time monitoring of LCACoAs in human cells. Subsequently, we applied LACSer in scientific studies investigating how disruption of ACSL enzymes differentially reduces cytosolic and mitochondrial LCACoA levels, and show how genetic disruption of an acyl-CoA binding protein (ACBP) alters mitochondrial accumulation of LCACoAs.
To describe and study the association between registered nurses' self-rated research utilization and their perception of their work climate.
Research utilization is an important part of evidence-based nursing, and registered nurses value a work climate that supports the possibility to work evidence-based.
This cross-sectional study was conducted using the Creative Climate Questionnaire together with three questions measuring instrumental, conceptual and persuasive research utilization. The analysis was done using variable- and pattern-oriented approaches.
An association was found between research utilization and experience of dynamism/liveliness. Women reported higher use of conceptual research utilization. Regarding work climate, younger registered nurses and registered nurses with less work experience gave higher scores for playfulness/humour and conflicts. The results showed an association between having a Bachelor's or Master's degree and higher instrumental research utilization.
Research utilizeir opinions and initiate discussions. There is a need to support clinical registered nurses to maintain their research utilization throughout their working career. The health care sector and the individual workplace should support registered nurses in furthering their academic level.
This study aimed to evaluate the difference of two various robotic technology applied in R- Total mesorectal excision (TME).
From May 2017 to December 2018, consecutive patients with rectal cancer who underwent da Vinci R-TME or Micro Hand S R-TME were enrolled. The comparative study was conducted on Short-term Operative, Oncological, and Functional Outcomes between two type of R-TME.
47 patients underwent da Vinci R-TME, and 43 patients underwent Micro Hand S R-TME. No difference occured between two groups in TME completeness, CRM, DRM, CRM involvement and DRM involvement, operative time, blood loss, protective ileostomy, conversion rate, number of retrieved lymph nodes, Comprehensive Complication Index (CCI), International Prostate Symptom Score (IPSS) or Wexner scores. However, the setup time in the Micro Hand S group was longer.
In the present study, both da Vinci R-TME and Micro Hand S R-TME achieve excellent TME quality with acceptable morbidity and postoperative function.

The microscopic morphology and chemical composition of the synthesized samples were analyzed by XRD, SEM, FT-IR, XPS, and other characterizations. BiVO4 /Cu/g-C3 N4 (BiVO4 /Cug-C3 N4 mass ratio was 11) photocatalyst had the optimal photocatalytic degradation activity for tetracycline (TC) wastewater under visible light irradiation (120 min, 74.8%). The introduction of Cu and Z-scheme heterojunction was further confirmed by UV-vis, PL, EIS, and capture mechanism analysis, which effectively accelerated the separation and transfer rate of photogenerated electron holes and enhanced the strong oxidation of h+ and •O2 - active species. BiVO4 /Cu/g-C3 N4 heterojunction photocatalytic material has potential application value in the removal of refractory pollutants in wastewater. PRACTITIONER POINTS A novel Z-scheme BiVO4 /Cu/g-C3 N4 photocatalyst with excellent photocatalytic activities and stability was prepared to treat tetracycline (TC) wastewater.
