Data_Sheet_1_The effect of trait mindfulness on social media rumination: Upward social comparison as a moderated mediator.CSV
Social media rumination means that social media users are inclined to worry about their posts, relevant situational elements, and ramifications of the posts on a regular basis, and it is one of the main reasons why people's use of social media is linked to unfavorable mental health and interpersonal results. Rumination is antagonistic to mindfulness, which entails paying attention on purpose and without judgment, and mindfulness appears to be useful in reducing rumination. However, in the context of social media, the nature of the relationship between rumination and mindfulness has gained less attention. The current research study indicates that trait mindfulness, upward social comparison (USC), and self-esteem are implicated in social media rumination (SMR). However, no research study has synthesized the findings into one model. Therefore, the current research study aims to explore the relationship between trait mindfulness and SMR, the mediating effect of USC, and the moderating effect of self-esteem. The model was tested using AMOS and the PROCESS macro in SPSS with bootstrapping. According to the findings, SC appears to have a moderated mediator effect on the relationship between trait mindfulness and SMR. Specifically, individuals with high mindfulness trait do not necessarily have less USC. Self-esteem moderated the above mediation. The beneficial effect of trait mindfulness on social media rumination is explained in depth in this study.</p
Effects of Ethanol Addition on <i>n</i>-Heptane Decomposition in Premixed Flames
The goal of this paper is to explain the effects of ethanol addition on <i>n</i>-heptane decomposition and partial oxidation processes. An experimental study of the oxidation of <i>n</i>-heptane in the absence and presence of ethanol has been performed. The specific flames were low-pressure (25 Torr), laminar, premixed flames at an equivalence ratio of 1.0. The experiment was performed with tunable synchrotron vacuum ultraviolet (VUV) photoionization and molecular-beam mass spectrometry. Major species on the centerline of each flame were identified by measurements of the photoionization mass spectrum and photoionization efficiency (PIE) spectra. Mole fraction profiles of these species were derived at the selected photon energies near the ionization thresholds. With the addition of ethanol, the partial oxidation of <i>n</i>-heptane into ketones was enhanced and 1-butene mainly decomposed to 1,3-butadiyne instead of 1,3-butadiene. Propargyl radicals were more important than butenynyl and butadienyl radicals in benzene formation
Carboxymethyl Chitosan-Coated Cyanidin-3‑<i>O</i>‑Glucoside-Beared Nanonutriosomes Suppress Palmitic Acid-Induced Hepatocytes Injury
Cyanidin-3-O-glucoside
(C3G) is classified
as
an anthocyanin (ACN) and is recognized for its remarkable antioxidant
properties. Yet, the inadequate physicochemical stability of C3G restricts
its potential for various biological applications. Thus, in this study,
carboxymethyl chitosan (CMC)-coated nanonutriosomes (NS) were synthesized
as a novel carrier for encapsulating C3G (CMC-C3G-NS) to improve C3G
stability. CMC-C3G-NS exhibited a diameter of less than 200 nm along
with an encouraging encapsulation efficiency exceeding 90%. Notably,
the formulated CMC-C3G-NS possessed better stability under various
pH, ionic, and oxygen conditions, improved controlled release properties,
and higher hepatocellular uptake than uncoated particles (C3G-NS),
indicating a longer retention time of C3G in a physiological environment.
Of utmost significance, CMC-C3G-NS demonstrated superior alleviating
effects against palmitic acid (PA)-induced oxidative hepatic damage
compared to C3G-NS. Our study provided promising nanocarriers with
the potential to deliver hydrophilic ACNs and controlled release properties
for PA-induced hepatotoxicity alleviation

Construction strategy of different cell sheets and nude mouse ectopic transplantation. (A) Multiple colony-derived hPDLSCs, hJBMMSCs, and the mixed cells of the two above in equal proportions were seeded into six-cell plates, and after induction by conditioned media, (B) PDLSCS, (C) JBMMSCS, and (D) CSCS were formed. (E, F) CBB/hTDM wrapped by cell sheets was cultured as the transplantation grafts. (G) Each mouse received two grafts, one on each side. The wounds were sutured to achieve primary closure.

Microscopic appearance of the scaffold materials and the adhesion of the cells to the scaffolds. (A, B) CBB showed a porous structure, and (E, F) the surface of hTDM showed dentinal tubules were sufficiently exposed. (C, D, G, H) The hPDLSCs and hJBMMSCs could adhere to these two scaffolds well, proliferate adequately, and extend excessively on the surface of CBB and hTDM. (PDF 511 kb
Cyanocobalamin (VB<sub>12</sub>) Bionic Enzyme-Assisted Photocatalytic Chain-Growth Polymerization for Detection of Lung Cancer Biomarkers
Cobalt-mediated radical polymerization is noted for its
great level
of control over the polymerization of acrylic and vinyl esters monomers,
even at high molar mass. Vitamin B12, a natural bionic
enzyme cobalt complex, involves the conversion of organic halides
to olefins through chain-growth polymerization. In this work, the
notion of R-Co(III) free radical persistent free radical effect and
vitamin B12 circulation were first reported for the perception
of ultralow abundance of microRNA-21, a lung cancer biomarker. Indeed,
most Co-containing catalytic reactions can occur under mild conditions
due to their minimal bond dissociation of the C–Co bond, with
blue light irradiation. Based on the intrinsic stability of the vitamin
B12 framework and recycling of the catalyst, it is evident
that this natural catalytic scheme has potential applications in medicinal
chemistry and biomaterials. In addition, this strategy, combined with
highly specific recognition probes and vitamin B12 circulation-mediated
chain-growth polymerization, has a detection limit as low as 910 aM.
Furthermore, it is sensitive for sensing in serum samples containing
biomarkers and shows great potential for RNA selection and amplification
sensing in clinical samples
Decorating Lithium Titanium-Phosphate Carbon Layers with Mo<sub>2</sub>C as Efficient Li-Ion Storage Electrode
Rapid charging technology is increasingly needed, especially
in
the case of continuous energy consumption. Na superionic conductor
(NASICON)-type materials are considered one of the most attractive
candidates for lithium-ion batteries (LIBs) due to their multiple
ionic channels and efficient kinetics. LiTi2(PO4)3 as a representative of the NASICON-type has been widely
studied because of its own advantages. LiTi2(PO4)3’s own poor electronic conductivity restricts
its further development. Herein, Mo2C was used to decorate
the external carbon layer of the LiTi2(PO4)3 to alleviate this problem. The excellent conductivity of
Mo2C can enhance the concentration of electrons in the
carbon layer and improve the Li+/e– conversion
efficiency of electrodes. Therefore, the LiTi2(PO4)3/C@Mo2C composites displayed outstanding
capacity retention of 86.8% after 4000 cycles under a high current
density of 10 C, showing excellent and stable electrochemical performance.
This work provides a fungible and convenient route for the hybrid
of NASICON-type and carbon-layer materials as high-performance electrodes
for Li-ion batteries
