This study aimed to compare the diagnostic efficacy of BRAF^(V600E) mutation and the Thyroid Imaging Reporting and Data System(TIRADS) classification in differentiating papillary thyroid cancers(PTCs) from benign lesions among BSRTC I, III, and V nodules.Methods: A total of 472 patients with 479 nodules were enrolled in this prospective study. Ultrasound, BRAF^(V600E) mutation testing, and FNAC were performed in each nodule, followed by surgery or regular ultrasound examination.Results: In the BSRTC I category, BRAF^(V600E) showed similar sensitivity, higher specificity, and lower accuracy when compared with TIRADS. In the BSRTC III/V category, the sensitivity, specificity, and accuracy of BRAF^(V600E) were similar to those of TIRADS. In comparison to BRAF^(V600E) alone, the combination of the two methods significantly improved sensitivity(BSRTC Ⅰ:93.6% vs. 67.7%, P < 0.01; BSRTC Ⅲ: 93.8% vs. 75.0%, P < 0.01; BSRTC V: 96.0% vs. 85.3%, P < 0.001). When compared with TIRADS alone, the combination improved sensitivity in BSRTC Ⅰ nodules(93.6% vs. 74.2%, P < 0.05), increased sensitivity and decreased accuracy in BSRTC III nodules(93.8% vs. 75.0%, P < 0.01, 91.0% vs. 93.6%, P < 0.01), and improved both sensitivity and accuracy in BSRTC V nodules(96.0% vs. 82.0%, P < 0.001; 94.2% vs. 81.3%, P < 0.001).Conclusions: BRAF^(V600E) exhibited higher specificity and lower accuracy compared with TIRADS in BSRTC Ⅰ nodules, while the two methods showed similar diagnostic value in BSRTC Ⅲ/Ⅴ nodules.

文摘Effective treatments for neuropathic pain are lacking due to our limited understanding of the mechanisms.The circRNAs are mainly enriched in the central nervous system.However,their function in various physiological and pathological conditions have yet to be determined.Here,we identified circFhit,an exon-intron circRNA expressed in GABAergic neurons,which reduced the inhibitory synaptic transmission in the spinal dorsal horn to mediate spared nerve injury-induced neuropathic pain.Moreover,we found that circFhit decreased the expression of GAD65 and induced hyperexcitation in NK1R^(+) neurons by promoting the expression of its parental gene Fhit in cis.Mechanistically,circFhit was directly bound to the intronic region of Fhit,and formed a circFhit/HNRNPK complex to promote Pol II phosphorylation and H2B monoubiquitination by recruiting CDK9 and RNF40 to the Fhit intron.In summary,we revealed that the exon-intron circFhit contributes to GABAergic neuron-mediated NK1R^(+) neuronal hyperexcitation and neuropathic pain via regulating Fhit in cis.

文摘The vast majority of in vitro studies have demonstrated that PINK1 phosphorylates Parkin to work together in mitophagy to protect against neuronal degeneration.However,it remains largely unclear how PINK1 and Parkin are expressed in mammalian brains.This has been difficult to address because of the intrinsically low levels of PINK1 and undetectable levels of phosphorylated Parkin in small animals.Understanding this issue is critical for elucidating the in vivo roles of PINK1 and Parkin.Recently,we showed that the PINK1 kinase is selectively expressed as a truncated form(PINK1–55)in the primate brain.In the present study,we used multiple antibodies,including our recently developed monoclonal anti-PINK1,to validate the selective expression of PINK1 in the primate brain.We found that PINK1 was stably expressed in the monkey brain at postnatal and adulthood stages,which is consistent with the findings that depleting PINK1 can cause neuronal loss in developing and adult monkey brains.PINK1 was enriched in the membrane-bound fractionations,whereas Parkin was soluble with a distinguishable distribution.Immunofluorescent double staining experiments showed that PINK1 and Parkin did not colocalize under physiological conditions in cultured monkey astrocytes,though they did colocalize on mitochondria when the cells were exposed to mitochondrial stress.These findings suggest that PINK1 and Parkin may have distinct roles beyond their well-known function in mitophagy during mitochondrial damage.

文摘High-entropy(HE)design provides ample opportunities for accessing catalysts with unique physiochemical properties for advanced energy and environmental applications.Although a variety of multi-cationic high-entropy materials(HEMs)have been identified,HEMs consisted of multiple cationic and anionic elements are still limited.Herein,we present the design and synthesis of a series of rutile-structured high-entropy oxy fluorides(HEOFs),including[RuO_(2)]_(x)[MgMnZnCoF_(2)]_(y),[MnO_(2)]_(x)[MgMnZnCoF_(2)]_(y),[MoO_(2)]_(x)[MgMnZnCoF_(2)]_(y),[SnO_(2)]_(x)[MgMnZnCoF_(2)]_(y)and[TiO_(2)]_(x)[MgMnZnCoF_(2)]_(y)(x:y=3:1,2:1,1:1).All the HEOFs are obtained through mechanochemical alloying rutile-structured oxide and fluoride precursors and the HEOFs inherit the crystal structures of the skeleton oxides.Moreover,the HEOFs exhibit enhanced electrocatalytic oxygen evolution reaction(OER)activity than the corresponding oneelement precursors.Typically,the best-performed HEOF[RuO_(2)]_(3)[MgMnZnCoF_(2)]_(1)catalyst requires an overpotential of 240 mV to achieve a current density of 10 mA cm^(-2),which is lower than RuO_(2)(291 mV),More impressively,the specific mass activity of[RuO_(2)]_(3)[MgMnZnCoF_(2)]_(1)is 537.1 A g_(Ru)^(-1)at1.55 V(vs RHE),which is ca.7.6 times that of RuO_(2)(70.5 A g_(Ru)^(-1)).The enhanced electrocata lytic OER performance obtained on[RuO_(2)]_(3)[MgMnZnCoF_(2)]_(1)is ascribed to the contribution of the different cationic and anionic elements that modulates the electronic structures of the pristine RuO_(2),which facilitates efficient OER kinetics.This work demonstrates the efficacy of high-entropy design towards approaching excellent catalysts for enhanced electrocatalysis.

文摘Micro(nano)plastics,as an emerging environmental pollutant,are gradually discovered in hyporheic zones and groundwaterworldwide.Recent studies have focused on the origin and spatial/temporal distribution of micro(nano)plastics in regional groundwater,together with the influence of their properties and effects of environmental factors on their transport.However,the transport of micro(nano)plastics in the whole hyporheic zone-groundwater system and the behavior of co-existing substances still lack a complete theoretical interpretation.To provide systematic theoretical support for that,this review summarizes the current pollution status of micro(nano)plastics in the hyporheic zone-groundwater system,provides a comprehensive introduction of their sources and fate,and classifies the transport mechanisms into mechanical transport,physicochemical transport and biological processes assisted transport fromthe perspectives ofmechanical stress,physicochemical reactions,and bioturbation,respectively.Ultimately,this review proposes to advance the understanding of the multi-dimensional hydrosphere transport of micro(nano)plastics centered on groundwater,themicroorganisms-mediated synergistic transformation and co-transport involving the intertidal circulation.Overall,this review systematically dissects the presence and transport cycles of micro(nano)plastics within the hyporheic zone-groundwater system and proposes prospects for future studies based on the limitations of current studies.

文摘Carbon electrocatalyst materials based on lignocellulosic biomass with multi-components,various dimensions,high carbon content,and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently.Due to the catalytic deficiency of neutral carbon atoms,the usage of single lignocellulosic-based carbon materials in electrocatalysis involving energy storage and conversion presents unsatisfactory applicability.However,atomic-level modulation of lignocellulose-based carbon materials can optimize the electronic structures,charge separation,transfer processes,and so forth,which results in substantially enhanced electrocatalytic performance of carbon-based catalysts.This paper reviews the recent advances in the rational design of lignocellulosic-based carbon materials as electrocatalysts from an atomic-level perspective,such as self/external heteroatom doping and metal modification.Then,through systematic discussion of the design principles and reaction mechanisms of the catalysts,the applications of the prepared lignocellulosic-based catalysts in rechargeable batteries and electrocatalysis are reviewed.Finally,the challenges in improving the catalytic performance of lignocellulosic-based carbon materials as electrocatalysts and the prospects in diverse applications are reviewed.This review contributes to the synthesis strategy of lignocellulose-based carbon electrocatalysts via atomic-level modulation,which in turn promotes the lignocellulose valorization for energy storage and conversion.

文摘Rechargeable chlorine-based battery recently emerged as a promising substitute for energy storage systems due to their high average operating voltage(~3.7 V)and large theoretical capacity of~754.9 mAh g-1.However,insufficient supply of chlorine(Cl_(2))and sluggish oxidation of NaCl to Cl_(2) limit its practical application.Covalent Organic Frameworks(COFs)have the potential to be ideal Cl_(2) host materials as Cl_(2) adsorbents for their abundant porosity and easily modifiable nature.In this work,the single atom Mn coordinated biomimetic phthalocyanine COFs are used for Cl_(2) capture and catalyst.The DFT reveals that ASMn and-NH_(2) significantly change the microenvironment around the active site,effectively promoting the oxidation of NaCl.When applied as the cathode material for Na-Cl_(2) batteries,the SAMn-COFs-NH2 electrode exhibits large reversible capacities and excellent high-rate cycling performances throughout 200 cycles based on the mechanism of highly reversible NaCl/Cl_(2) redox reactions.Even at the temperature as low as-40℃,the SAMn-COFs-NH2 cathode showed stable discharge ca-pacities at~1000 mAh g^(-1) over 50 cycles with a voltage plateau of~3.3 V.This work may provide new insights for the investigation of chlorine-based electrochemical redox mechanisms and the design of green nanoscaled electrodes for high-property chlorine-based batteries.

文摘Objective To explore and quantify the association of hot night exposure during the sperm development period(0–90 lag days) with semen quality.Methods A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014–2020were recruited in this multicenter study.Two indices(i.e.,hot night excess [HNE] and hot night duration[HND]) were used to estimate the heat intensity and duration during nighttime.Linear mixed models were used to examine the association between hot nights and semen quality parameters.Results The exposure-response relationship revealed that HNE and HND during 0–90 days before semen collection had a significantly inverse association with sperm motility.Specifically,a 1 ℃ increase in HNE was associated with decreased sperm progressive motility of 0.0090(95% confidence interval[CI]:–0.0147,–0.0033) and decreased total motility of 0.0094(95% CI:–0.0160,–0.0029).HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021(95% CI:–0.0040,–0.0003) and 0.0023(95% CI:–0.0043,–0.0002),respectively.Consistent results were observed at different temperature thresholds on hot nights.Conclusion Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

文摘Accurate and real-time detection of hydrogen(H_(2))is essential for ensuring energy security.Fiber-optic H_(2) sensors are gaining attention for their integration and remote sensing capabilities.However,they face challenges,including complex fabrication processes and limited response times.Here,we propose a fiber-optic H_(2) sensing tip based on Tamm plasmon polariton(TPP)resonance,consisting of a multilayer metal/dielectric Bragg reflector deposited directly on the fiber end facet,simplifying the fabrication process.The fiber-optic TPP(FOTPP)tip exhibits both TPP and multiple Fabry-Perot(FP)resonances simultaneously,with the TPP employed for highly sensitive H_(2) detection.Compared to FP resonance,TPP exhibits more than twice the sensitivity under the same structural dimension without cavity geometry deformation.The excellent performance is attributed to alterations in phase-matching conditions,driven by changes in penetration depth of TPP.Furthermore,the FP mode is utilized to achieve an efficient photothermal effect to catalyze the reaction between H_(2) and the FOTPP structure.Consequently,the response and recovery speeds of the FOTPP tip under resonance-enhanced photothermal assistance are improved by 6.5 and 2.1 times,respectively.Our work offers a novel strategy for developing TPP-integrated fiber-optic tips,refines the theoretical framework of photothermal-assisted detection systems,and provides clear experimental evidence.

文摘Rotational dynamics simulations of neutral O_(2)molecules driven by linearly,elliptically and circularly polarized femtosecond pulsed lasers are carried out using a full quantum time-dependent wave packet evolution method.Here,the direction of laser propagation is set along the z axis,and the polarization plane is restricted to the xy plane.The results indicate that the alignment of O_(2)molecules in the z direction is weakly affected by varying the ellipticity when the total laser intensity is held constant.For rotation within the xy plane,the linearly polarized laser significantly excites rotational motion,with the degree of excitation increasing as the ellipticity increases.In contrast,under the influence of a circularly polarized laser,the angular distribution of O_(2)molecules in the xy plane remains isotropic.Additionally,the effects of the initial rotational quantum number,the temperature of the O_(2)molecules and the nuclear spin on laser-induced alignment are discussed.
