Therefore, the aim of the study was to determine the retrospective epidemiological profile of HPV-related cancer in the United Arab Emirates (UAE). The incidence profiling of HPV-related cancers in males and females of UAE of all ages ranged from a minimum of 0.6% to a maximum of 4.5% for testes cancer and colon cancer respectively in males;whilst in females it ranged from a minimum of 1.0% and a maximum of 34% for Hodgkin lymphoma, kidney, bladder, liver and pancreas cancer and breast cancer, respectively. The incidence profiling of HPV-related cancers in males and females of ages 15 - 44 years old ranged from a minimum of 0.1% to a maximum of 11.2% for pancreas cancer, and colon and rectum cancer respectively in males, whilst in females it ranged from a minimum of 0.1% and a maximum of 18% for pancreas and breast cancer, respectively. The mortality profiling of HPV-related cancers in males and females of all ages in the UAE ranged from a minimum of 0.1% for Hodgkin lymphoma and testicular cancer to a maximum of 4.5% for colon and rectum cancer respectively in males, whilst in females it ranged from a minimum of 0.2% and a maximum of 4.5% for pancreas and breast cancer, respectively. The mortality profiling of HPV-related cancers mortality in males and females of ages 15 - 44 years old in the UAE ranged from a minimum of 0.2% to a maximum of 4.3% for testicular cancer and colon cancer respectively in males, whilst in females it ranged from a minimum of 0.2% and a maximum of 7.2% for bladder and breast cancer respectively. In conclusion, the profiling of HPV-related cancers in UAE for both males and females of all ages is similar to that reported for other parts of the world.展开更多

Methods: The subjects were 17 adult women (height, 160.1 ± 5.1 cm;weight, 54.3 ± 10.5 kg;age, 57.8 ± 8.3 years) living in the community and attending a fitness club. The subjects performed a coordination exercise called Life Kinetik®. The subjects responded to the Two-Dimensional Mood Scale–Short Term before and after performing 30 minutes of Life Kinetik®. The results were tabulated and four psychological states were calculated (i.e., vitality, stability, pleasure, and arousal). The pre- and post-implementation results were statistically analyzed using a corresponding t-test. Results: Significant differences were found in activation and arousal levels, but not in stability and comfort levels. Conclusion: The coordination exercise, Life Kinetik®, was found to be an exercise program with potential psychological benefits, as it could change women’s psychological condition to active and excited states.展开更多

文摘Compared to aqueous-phase electrocatalytic nitrogen reduction reaction(NRR),lithium-mediated NRR(Li-NRR)theoretically enhances the intrinsic activity of NH3 production through spontaneous exothermic reactions between Li and N_(2).However,the in-situ generated solid electrolyte interphase(SEI)during the reaction slows down the Li^(+)transport and nucleation kinetics,which further hinders the subsequent activation and protonation processes.Herein,a sophisticated amorphous-crystalline heterostructured SEI of Zn-LiF is formed by additive engineering.The concerted electron interplay between amorphous and crystalline domains is prone to generate lithiophobic Zn and lithiophilic LiF sites,where lithiophobic Zn accelerates Li^(+)diffusion within the SEI and avoids high concentration polarization,and lithiophilic LiF ensures homogeneous nucleation of diffused Li^(+)and its participation in subsequent reactions.Therefore,compared to conventional SEI,a more than 8-fold performance improvement is achieved in the additive-engineered heterogeneous lithiophobic-lithiophilic SEI,which exhibits a high NH_(3)yield rate of 11.58 nmol s^(−1)cm^(−2)and a Faradaic efficiency of 32.97%.Thus,exploiting the synergistic effects in heterogeneous lithiophobic-lithiophilic structures to achieve functional complementarity between different components opens a new avenue toward high-performance Li-NRR.
文摘Dispersing metals from nanoparticles to clusters is often achieved using ligand protection methods,which exhibit unique properties such as suppressing structure-sensitive side reactions.However,this method is limited by the use of different metal precursor salts corresponding to different ligands.An alternative approach,the ion exchange(IE)method,can overcome this limitation to some extent.Nevertheless,there is still an urgent need to address the stabilization of metals(especially precious metals)by using IE method.Here,we reported a Pt cluster catalyst prepared mainly by anchoring Pt atoms via O located near the framework Zn in zincosilicate zeolites and riveted by zeolite surface rings after reduction(reduced Pt/Zn-3-IE).The catalyst can achieve an initial propane conversion of 26%in a pure propane atmosphere at 550℃and shows little deactivation even after 7.5 d of operation.Moreover,the alteration of catalyst by the introduction of framework Zn was also highlighted and interpreted.

文摘Cu-based metal-organic frameworks(Cu-MOFs)electrocatalysts are promising for CO_(2)reduction reactions(CO_(2)RR)to produce valuable C_(2+)products.However,designing suitable active sites in Cu-MOFs remains challenging due to their inherent structural instability during CO_(2)RR.Here we propose a synergistic strategy through thermal annealing and electrochemicalactivation process for in-situ reconstruction of the pre-designed Cu-MOFs to produce abundant partially oxidized Cu(Cu^(δ+))active species.The optimized MOF-derived Cu^(δ+)electrocatalyst demonstrates a highly selective production of C_(2+)products,with the Faradaic Efficiency(FE)of 78±2%and a partial current density of-46 m A cm-2at-1.06 VRHEin a standard H-type cell.Our findings reveal that the optimized Cu^(δ+)-rich surface remains stable during electrolysis and enhances surface charge transfer,leading to an increase in the concentration of*CO intermediates,thereby highly selectively producing C_(2+)compounds.This study advances the controllable formation of MOF-derived Cu^(δ+)-rich surfaces and strengthens the understanding of their catalytic role in CO_(2)RR for C_(2+)products.

文摘Conversion of solar energy into H_(2) by photoelectrochemical(PEC)water splitting is recognized as an ideal way to address the growing energy crisis and environmental issues.In a typical PEC cell,the construction of photoanodes is crucial to guarantee the high efficiency and stability of PEC reactions,which fundamentally rely on rationally designed semiconductors(as the active materials)and substrates(as the current collectors).In this review work,we start with a brief introduction of the roles of substrates in the PEC process.Then,we provide a systematic overview of representative strategies for the controlled fabrication of photoanodes on rationally designed substrates,including conductive glass,metal,sapphire,silicon,silicon carbide,and flexible substrates.Finally,some prospects concerning the challenges and research directions in this area are proposed.

文摘With the merits of the high energy density of batteries and power density of supercapacitors,the aqueous Zn-ion hybrid supercapacitors emerge as a promising candidate for applications where both rapid energy delivery and moderate energy storage are required.However,the narrow electrochemical window of aqueous electrolytes induces severe side reactions on the Zn metal anode and shortens its lifespan.It also limits the operation voltage and energy density of the Zn-ion hybrid supercapacitors.Using'water in salt'electrolytes can effectively broaden their electrochemical windows,but this is at the expense of high cost,low ionic conductivity,and narrow temperature compatibility,compromising the electrochemical performance of the Zn-ion hybrid supercapacitors.Thus,designing a new electrolyte to balance these factors towards high-performance Zn-ion hybrid supercapacitors is urgent and necessary.We developed a dilute water/acetonitrile electrolyte(0.5 m Zn(CF_(3)SO_(3))_(2)+1 m LiTFSI-H_(2)O/AN)for Zn-ion hybrid supercapacitors,which simultaneously exhibited expanded electrochemical window,decent ionic conductivity,and broad temperature compatibility.In this electrolyte,the hydration shells and hydrogen bonds are significantly modulated by the acetonitrile and TFSI-anions.As a result,a Zn-ion hybrid supercapacitor with such an electrolyte demonstrates a high operating voltage up to 2.2 V and long lifespan beyond 120,000 cycles.

文摘Monochloroacetic acid(MCAA)is identified as a highly carcinogenic disinfection by-product in chlorinated drinking water.In this study,a series of CeO_(2)-supported Pd catalysts(Pd/MCeO_(2))were synthesized through one-step calcination of Pd-loaded Ce-UiO-66-BDC(CeMOF),and the liquid-phase catalytic hydrodechlorination of MCA A was explored using these catalysts.For comparison,Pd/CeO_(2)catalysts were additionally synthesized using the conventional impregnation method.The characterization results reveal that the catalysts exhibit strong metal-support interaction,leading to high Pd dispersion and Pd^(n+)content.Additionally,the calcination temperature significantly influences catalytic performance,with the catalyst calcined at 500℃(Pd/MCeO_(2)-500)demonstrating the highest catalytic activity and achieving complete dechlorination of MCA A within 50 min.Furthermore,it is found that the catalytic MCAA hydrodechlorination using the catalysts adheres to the Langmuir-Hinshelwood model.Accordingly,low reaction pH is favorable for the catalytic hydrodechlorination of MCAA,enhancing MCAA adsorption on the catalyst surface due to the electrostatic interaction between MCAA and the catalyst surface.Theoretical results suggest that the presence of Pd^(n+)efficiently facilitates MCAA adsorption and C-Cl cleavage,thus significantly enhancing the liquid-phase catalytic hydrodechlorination.

文摘AIM:To investigate the proliferation regulatory effect of cone-rod homeobox(CRX)in retinal pigment epithelium(RPE)and retinoblastoma(RB)cells to explore the potential application and side effect(oncogenic potential)of CRXbased gene therapy in RPE-based retinopathies.METHODS:Adult human retinal pigment epithelial(ARPE)-19 and human retinal pigment epithelial(RPE)-1 cells and Y79 RB cell were used in the study.Genetic manipulation was performed by lentivirus-based technology.The cell proliferation was determined by a CellTiter-Glo Reagent.The mRNA and protein levels were determined by quantitative real-time polymerase chain reaction(qPCR)and Western blot assay.The transcriptional activity of the promoter was determined by luciferase reporter gene assay.The bindings between CRX and transcription factor 7(TCF7)promoter as well as TCF7 and the promoters of TCF7 target genes were examined by chromatin immunoprecipitation(ChIP)assay.The transcription of the TCF7 was determined by a modified nuclear run-on assay.RESULTS:CRX overexpression and knockdown significantly increased(n=3,P<0.05 in all the cells)and decreased(n=3,P<0.01 in all the cells)the proliferation of RPE and RB cells.CRX overexpression and knockdown significantly increased and deceased the mRNA levels of Wnt signaling target genes[including MYC proto-oncogene(MYC),JUN,FOS like 1(FOSL1),CCND1,cyclin D2(CCND2),cyclin D3(CCND3),cellular communication network factor 4(CCN4),peroxisome proliferator activated receptor delta(PPARD),and matrix metallopeptidase 7(MMP7)]and the luciferase activity driven by the Wnt signaling transcription factor(TCF7).TCF7 overexpression and knockdown significantly increased and decreased the proliferation of RPE and RB cells and depletion of TCF7 significantly abolished the stimulatory effect of CRX on the proliferation of RPE and RB cells.CRX overexpression and knockdown significantly increased and decreased the mRNA level of TCF7 and the promoter of TCF7 was significantly immunoprecipitated by CRX antibody.CONCLUSION:CRX transcriptionally activates TCF7 to promote the proliferation of RPE and RB cells in vitro.CRX is a potential target for RPE-based regenerative medicine.The potential risk of this strategy,tumorigenic potential,should be considered.
文摘Dispersing metals from nanoparticles into clusters or single atoms often exhibits unique properties such as the inhibition of structure-sensitive side reactions.Here,we reported the use of ion exchange(IE)methods and direct hydrogen reduction to achieve high dispersion of Co species on zincosilicate.The obtained 2Co/Zn-4-IE catalyst achieved an initial propane conversion of 41.4%at a temperature of 550℃in a 25%propane and 75%nitrogen atmosphere for propane dehydrogenation.Visualization of the presence of Co species within specific rings(alpha-α,beta-βand delta-δ)was obtained by aberration-corrected scanning transmission electron microscopy.A series of Fourier transform infrared spectra confirmed the anchoring of Co by specific hydroxyl groups in zincosilicate and the specific coordination environment of Co and its presence in the rings essentially as a single site.The framework Zn for the modulation of the microenvironment and the presence of Co species as Lewis acid active sites(Co-O4)was also supported by density functional theory calculations.
文摘Objective: This study aimed to evaluate the immediate psychological effects of coordination exercises on women in Japan. Methods: The subjects were 17 adult women (height, 160.1 ± 5.1 cm;weight, 54.3 ± 10.5 kg;age, 57.8 ± 8.3 years) living in the community and attending a fitness club. The subjects performed a coordination exercise called Life Kinetik®. The subjects responded to the Two-Dimensional Mood Scale–Short Term before and after performing 30 minutes of Life Kinetik®. The results were tabulated and four psychological states were calculated (i.e., vitality, stability, pleasure, and arousal). The pre- and post-implementation results were statistically analyzed using a corresponding t-test. Results: Significant differences were found in activation and arousal levels, but not in stability and comfort levels. Conclusion: The coordination exercise, Life Kinetik®, was found to be an exercise program with potential psychological benefits, as it could change women’s psychological condition to active and excited states.
