Comparative efficacy of psychological interventions on anxiety and depression in patients with cancer: A systematic review and network meta-analysis.

BACKGROUND: Numerous studies have demonstrated that psychological interventions are effective in alleviating anxiety and depression in patients with cancer. However, the optimal psychological intervention to alleviate anxiety and depression in patients with cancer remains unknown. This study was carried out to compare and rank the comparative effectiveness of various psychological interventions on anxiety and depression in patients with cancer. METHODS: Databases, namely PubMed, Embase, Cochrane Library, Web of Science, PsycINFO, CNKI, WanFang, VIP and CBM were systematically searched from their inception dates to December 2023 for randomized controlled trials of psychological interventions for anxiety and depression in patients with cancer. Utilizing the Cochrane Review Manager 5.4, we evaluated the risk of bias in the studies included in the current study based on the Cochrane Handbook 5.1.0 Methodological Quality Evaluation Criteria. The NMA was conducted using STATA 15.0. This study did not involve human participants and therefore did not require ethical approval. RESULTS: Thirty-one randomized controlled trials involving 3471 participants were included. MT [SMD = 1.35, 95% CI (0.76, 1.93)] and cognitive behavioral therapy (CBT) [SMD = 0.97, 95% CI (0.53, 1.42)] were superior to usual care in alleviating anxiety. Besides, interpersonal psychotherapy (IPT) [SMD = 1.17, 95% CI (0.06, 2.28)], CBT [SMD = 0.97, 95 % CI (0.63, 1.30)], and MT [SMD = 0.93, 95% CI (0.35, 1.50)] were superior to usual care in alleviating depression. In addition, CBT was superior to family therapy in alleviating depression [SMD = 0.73, 95% CI (0.08, 1.38)]. The MT, CBT, and IPT ranked in the top three in alleviating anxiety, while IPT, CBT, and MT ranked in the top three in alleviating depression. CONCLUSION: MT and IPT would be a more appropriate option in alleviating anxiety and depression in patients with cancer, respectively. This study also suggested that CBT had a significant effect in alleviating negative emotions in patients with cancer. However, the results need to be validated by high-quality and large-sample studies.

Li-Ion Transfer Mechanism of Gel Polymer Electrolyte with Sole Fluoroethylene Carbonate Solvent.

Although gel polymer electrolytes (GPEs) represent a promising candidate to address the individual limitations of liquid and solid electrolytes, their extensive development is still hindered due to the veiled Li-ion conduction mechanism. Herein, the related mechanism in GPEs is extensively studied by developing an in situ polymerized GPE comprising fluoroethylene carbonate (FEC) solvent and carbonate ester segments (F-GPE). Practically, although with high dielectric constant, FEC fails to effectively transport Li ions when acting as the sole solvent. By sharp contrast, F-GPE demonstrates superior electrochemical performances, and the related Li-ion transfer mechanism is investigated using molecular dynamics simulations and 7 Li/6 Li solid-state nNMR spectroscopy. The polymer segments are extended with the swelling of FEC, then an electron-delocalization interface layer is generated between abundant electron-rich groups of FEC and the polymer ingredients, which works as an electron-rich "Milky Way" and facilitates the rapid transfer of Li ions by lowering the diffusion barrier dramatically, resulting in a high conductivity of 2.47 × 10-4  S cm-1 and a small polarization of about 20 mV for Li//Li symmetric cell after 8000 h. Remarkably, FEC provides high flame-retardancy and makes F-GPE remains stable under ignition and puncture tests.

Chloride-Reinforced Solid Polymer Electrolyte for High-Performance Lithium Metal Batteries.

Flexible solid-state polymer electrolytes (SPEs) enable intimate contact with the electrode and reduce the interfacial impedance for all-solid-state lithium batteries (ASSLBs). However, the low ionic conductivity and poor mechanical strength restrict the development of SPEs. In this work, the chloride superionic conductor Li2ZrCl6 (LZC) is innovatively introduced into the poly(ethylene oxide) (PEO)-based SPE to address these issues since LZC is crucial for improving the ionic conductivity and enhancing the mechanical strength. The as-prepared electrolyte provides a high ionic conductivity of 5.98 × 10-4 S cm-1 at 60 °C and a high Li-ion transference number of 0.44. More importantly, the interaction between LZC and PEO is investigated using FT-IR and Raman spectroscopy, which is conducive to inhibiting the decomposition of PEO and beneficial to the uniform deposition of Li ions. Therefore, a minor polarization voltage of 30 mV is exhibited for the Li||Li cell after cycling for 1000 h. The LiFePO4||Li ASSLB with 1% LZC-added composite electrolyte (CPE-1% LZC) demonstrates excellent cycling performance with a capacity of 145.4 mA h g-1 after 400 cycles at 0.5 C. This work combines the advantages of chloride and polymer electrolytes, exhibiting great potential in the next generation of all-solid-state lithium metal batteries.

The role of cyclophilins in viral infection and the immune response.

Cyclophilins (Cyps) are a subgroup of peptidyl-prolyl cis-trans isomerases (PPIases) that contain a highly conserved domain of PPIases. Sixteen Cyps have been identified in humans, among which the functions of five classical Cyp subtypes (CypA, B, C, D, and 40) have been studied in more detail. Cyps are widely expressed in almost all human tissues and are involved in several intracellular signaling pathways such as oxidative stress, mitochondrial dysfunction, cell migration, and apoptosis. Several studies have also demonstrated that Cyps play an important role in the development of cardiovascular diseases, neurodegeneration, cancer, and other diseases. However, as regulators of intercellular communication, Cyps have increasingly attracted attention as a result of their implications in viral infection. The specific motifs of Cyps can be targeted by viral proteins and thus promote either a viral infection or an antiviral response. This review highlights the present understanding of Cyps in viral infection and immune response. These effects will facilitate revealing the molecular mechanisms of several diseases induced by viruses and may provide novel insight into the development of corresponding drug-based treatment methods.

Dual In Situ Polymerization Strategy Endowing Rapid Ion Transfer Capability of Polymer Electrolyte toward Ni-Rich-Based Lithium Metal Batteries.

Poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) is one of the most promising candidate electrolyte matrices for high energy batteries. However, the spherical skeleton structure obtained through the conventional method fails to build continuous Li ion transmission channels due to the slow volatilization of high boiling solvent, leading to inferior cycling performance, especially in a Ni-rich system. Herein, a novel strategy is presented to enrich the Li ion transfer paths and improve the Li ion migration kinetics. The tactic is to prepare cross-linked segments through the PVDF-HFP matrix by adopting free radical polymerization and Li salt induced ring-opening polymerization. Most significantly, the visualization of the structure of as-prepared electrolyte is innovatively realized with the combination of polarization microscopy, transmission electron microscopy, scanning electron microscope-energy dispersive spectroscopy, PVDF-HFP, and cross-linked network form interconnected microstructures. Therefore, poly(glycidyl methacrylate and acrylonitrile)@poly(vinylidene fluoride-hexafluoropropylene) electrolyte presents a high ionic conductivity (1.04 mS cm-1 at 30 °C) and a stable voltage profile for a Li/Li cell after 1200 h. After assembly with a LiNi0.8 Co0.15 Al0.05 O2 cathode, a high discharge specific capacity of 190.3 mAh g-1 is delivered, and the capacity retention reaches 88.2% after 100 cycles. This work provides a promising method for designing high-performance polymer electrolytes for lithium metal batteries.

Hierarchical Sulfide-Rich Modification Layer on SiO/C Anode for Low-Temperature Li-Ion Batteries.

The silicon oxide/graphite (SiO/C) composite anode represents one of the promising candidates for next generation Li-ion batteries over 400 Wh kg-1 . However, the rapid capacity decay and potential safety risks at low temperature restrict their widely practical applications. Herein, the fabrication of sulfide-rich solid electrolyte interface (SEI) layer on surface of SiO/C anode to boost the reversible Li-storage performance at low temperature is reported. Different from the traditional SEI layer, the present modification layer is composed of inorganic-organic hybrid components with three continuous layers as disclosed by time-of-flight secondary ion mass spectrometry (TOF-SIMS). The result shows that ROSO2 Li, ROCO2 Li, and LiF uniformly distribute over different layers. When coupled with LiNi0.8 Co0.1 Mn0.1 O2 cathode, the capacity retention achieves 73% at -20 °C. The first principle calculations demonstrate that the gradient adsorption of sulfide-rich surface layer and traditional intermediate layer can promote the desolvation of Li+ at low temperature. Meanwhile, the inner LiF-rich layer with rapid ionic diffusion capability can inhibit dendrite growth. These results offer new perspective of developing advanced SiO/C anode and low-temperature Li-ion batteries.

Cyclophilin A regulates the apoptosis of A549 cells by stabilizing Twist1 protein.

Cyclophilin A (CypA, also known as PPIA) is an essential member of the immunophilin family. As an intracellular target of the immunosuppressive drug cyclosporin A (CsA) or a peptidyl-prolyl cis/trans isomerase (PPIase), it catalyzes the cis-trans isomerization of proline amidic peptide bonds, through which it regulates a variety of biological processes, such as intracellular signaling, transcription and apoptosis. In this study, we found that intracellular CypA enhanced Twist1 phosphorylation at Ser68 and inhibited apoptosis in A549 cells. Mechanistically, CypA could mediate the phosphorylation of Twist1 at Ser68 via p38 mitogen-activated protein kinase (also known as MAPK14), which inhibited its ubiquitylation-mediated degradation. In addition, CypA increased interaction between Twist1 and p65 (also known as RELA), as well as nuclear accumulation of the Twist1-p65 complex, which regulated Twist1-dependent expression of CDH1 and CDH2. Our findings collectively indicate the role of CypA in Twist1-mediated apoptosis of A549 cells through stabilizing Twist1 protein.

Boosting the Electrochemical Performance of a Spinel Cathode with the In Situ Transformed Allogenic Li-Rich Layered Phase.

High-voltage spinel materials have attracted widespread attention because of their advantages such as good rate performance, low cost, abundant source, and easy preparation. However, the Mn dissolution and Jahn-Teller effect of spinel materials during cycling limit their practical application. In this paper, the allogenic composites (1 - x)Li(Ni0.2Co0.1Mn0.7)2 O4·xLi1.2(Ni0.2Co0.1Mn0.7)0.8O2 (x = 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5) are developed by the carbonate co-precipitation method combined with the high-temperature sintering method, which are certified by the X-ray diffraction (XRD) spectrum and transmission electron microscopy (TEM) image. The results show that the lithium-rich phase of the allogenic composites can effectively improve the initial discharge capacity, alleviate the side reaction between the spinel material and the electrolyte, and improve the cycle stability. This work reveals the relationship between the structure and electrochemical performance of the in situ transformed spinel@Li-rich allogenic composites and provide a new clue to design a high-performance spinel cathode for advanced Li-ion batteries.

SARS-CoV-2 3C-like protease antagonizes interferon-beta production by facilitating the degradation of IRF3.

The prevalence of SARS-CoV-2 is a great threat to global public health. However, the relationship between the viral pathogen SARS-CoV-2 and host innate immunity has not yet been well studied. The genome of SARS-CoV-2 encodes a viral protease called 3C-like protease. This protease is responsible for cleaving viral polyproteins during replication. In this investigation, 293T cells were transfected with SARS-CoV-2 3CL and then infected with Sendai virus (SeV) to induce the RIG-I like receptor (RLR)-based immune pathway. q-PCR, luciferase reporter assays, and western blotting were used for experimental analyses. We found that SARS-CoV-2 3CL significantly downregulated IFN-ß mRNA levels. Upon SeV infection, SARS-CoV-2 3CL inhibited the nuclear translocation of IRF3 and p65 and promoted the degradation of IRF3. This effect of SARS-CoV-2 3CL on type I IFN in the RLR immune pathway opens up novel ideas for future research on SARS-CoV-2.

Tailoring 3D Carbon Foam using CNTs and MnO2 to Fabricate Stable Lithium/Dissolved Lithium Polysulfide Batteries.

The lithium-sulfur (Li-S) battery is an ideal electrochemical energy storage system owing to the high theoretical energy density and acceptable cost of finance and the environment. However, some disadvantages, including low electrical conductivity, poor sulfur utilization, and rapid capacity fading, obstruct its practical application. In this work, 3D carbon foam from a melamine resin is synthesized via high-temperature calcination. Carbon nanotubes (CNTs) and MnO2 are utilized to tailor the properties of the 3D cathode collector in the liquid Li2S6-containing Li-S battery without additional conductive agents, binders, and aluminum foil. Herein, the decorated MnO2 on the carbon fiber foam prolongs the lifespan of the Li-S battery, and adding CNTs is beneficial to enhance the capacity and cyclic performance of the Li-S battery under high sulfur loading. The Li-S battery with a sulfur loading of 3 mg cm-2 possesses a reversible capacity of 437.9 mA h g-1 after 400 cycles at 0.1 C. The capacity could be maintained at 568 mA h g-1 at 0.1 C after 80 cycles when the sulfur loading increases to 6 mg cm-2.

Influence of Ni/Mn distributions on the structure and electrochemical properties of Ni-rich cathode materials.

To reveal the influence of element distribution on the structure and electrochemical performances of Ni-rich layered cathode materials, LiNi0.68Co0.13Mn0.19O2 (NCM) with four types of Ni/Mn distributions (homogeneous, core-shell, multi-shell and concentration-gradient structures) is designed and synthesized with a combination of co-precipitation and high-temperature solid-state method. Ni/Mn distributions of the as-prepared NCM cathode materials are investigated with focused ion beam (FIB) and energy disperse X-ray spectrum (EDS) line scanning on the cross-section of single particles, which illustrate that NCM materials with the desired Ni/Mn distributions are successfully prepared. For the three spherical heterogeneous NCM materials, the center is the Ni-rich component while the surface is the Mn-rich component. Ni/Mn distributions between the center and surface components are in different forms. Studies imply that the heterogeneous samples exhibit smaller cation disordering, lower charge transfer resistance, higher Li+ diffusion coefficient and higher structural stability than the homogeneous one. Therefore, the heterogeneous samples, especially the multi-shell and concentration-gradient ones, display improved cycling and thermal stability compared to the homogeneous one. These results manifest that multi-shell and concentration-gradient structures are effective strategies to modify the layered NCM cathode materials for Li-ion batteries.

Unravelling the Structure and Electrochemical Performance of Li-Cr-Mn-O Cathodes: From Spinel to Layered.

To explore a new series of cathode materials with high electrochemical performance, the spinel-layered (1 - x)[LiCrMnO4]· x[Li2MnO3·LiCrO2] ( x = 0, 0.25, 0.5, 0.75, and 1) composites are synthesized with the sol-gel method. X-ray diffraction, high-resolution transmission electron microscopy, selected area electron diffraction, and Raman spectra reveal that the structure of the (1 - x)[LiCrMnO4]· x[Li2MnO3·LiCrO2] cathode materials evolves from spinel to hybrid spinel-layered and layered structures with the increase of the Li concentration. Test results reveal that the structure and electrochemical performance of (1 - x)[LiCrMnO4]· x[Li2MnO3·LiCrO2] ( x = 0.25, 0.5 and 0.75) composites have the characteristics of both spinel ( x = 0) and Li-rich layered phases ( x = 1). In particular, x = 0.5 and 0.75 electrodes exhibit relatively high capacity retention and rate capability, which is mainly ascribed to the synergistic effect of the spinel and Li-rich layered phases, the 3D Li-ion diffusion channels of the spinel phase, and the low charge-transfer resistance ( Rct) and Warburg diffusion impedance ( Wo).

Improved Performances of LiNi0.8Co0.15Al0.05O2 Material Employing NaAlO2 as a New Aluminum Source.

To prepare a high-performance LiNi0.8Co0.15Al0.05O2 material (LNCA) for Li-ion batteries, a new aluminum source, NaAlO2, is employed in the coprecipitation step for the first time, and the effect of aluminum sources on the performances is systematically investigated. Different from the traditional preparation process using Al(NO3)3 as the aluminum source, the preparation process of the Ni0.8Co0.15Al0.05(OH)2.05 precursor from NaAlO2 is a hydrolysis process, during which the fast precipitation of Al3+ and the formation of a flocculent precipitate can be effectively avoided. As expected, stoichiometric LNCA with uniform element distribution, low cation mixing and well-ordered layered structure is obtained from NaAlO2, which is designed as LNCA-NaAlO2. The characterization and electrochemical measurements show that LNCA-NaAlO2 exhibits significantly improved performances (such as tap density, initial discharge capacity and volumetric energy density, rate performance, cycle performance, electrochemical stability, microstructure stability, and storage stability) compared to the performances of those prepared from Al(NO3)3 (LNCA-Al(NO3)3), indicating that it is an effective strategy to preparing high-performance LNCA employing NaAlO2 as the aluminum source.

Expression of CD56 in patients with adenomyosis and its correlation with dysmenorrhea.

OBJECTIVE: To investigate the expression of CD56 in endometrial samples from patients with adenomyosis and its relationship with menstrual cycle phase and severity of dysmenorrhea. STUDY DESIGN: 40 patients with histologically proved adenomyosis (proliferative n=20; secretory n=20) and dysmenorrhea were examined in this study, control groups includes 20 patients with adenomyosis without dysmenorrhea (main complaint: menorrhagia) and 20 patients without adenomyosis who had undergone hysterectomy for non-endometrial pathology (no dysmenorrhea medical history). Immunohistochemical staining against CD56 was performed for the eutopic and ectopic endometrium from patients with adenomyosis and the control samples. The expression of CD56 was determined by calculating the H-score and the severity of dysmenorrhea was determined using the visual analogue scale. The menstrual cycle status and the disease severity were compared to the levels of staining. RESULT(S): CD56 was expressed mainly in the endometrial glandular epithelium in patients with adenomyosis and normal endometrium. The epithelial staining intensity of CD56 in ectopic lesions of adenomyosis with dysmenorrhea was obviously higher than in the corresponding eutopic endometrium and control groups (P<0.01). There were no statistical differences in the expression between normal endometrium, eutopic endometrium of adenomyosis with dysmenorrhea and adenomyostic samples without dysmenorrhea. For eutopic endometrium in adenomyosis with dysmenorrhea, expression was higher in the secretory phases than in the proliferative phase (P<0.05). The increased CD56 immunoreactivity correlated with the severity of dysmenorrhea (spearman rho=0.84, P<0.01). CONCLUSION(S): These findings suggest that the expression of CD56 in adenomyosis is positively associated with the severity of dysmenorrhea. Endometrial glandular epithelium is likely to secrete more CD56 and stimulating nerve growth in the stroma, which could then play a role in the pathogenesis of adenomoysis-related dysmenorrhea.

Understanding the Origin of Enhanced Performances in Core-Shell and Concentration-Gradient Layered Oxide Cathode Materials.

Core-shell and concentration-gradient layered oxide cathode materials deliver superior electrochemical properties such as long cycle life and outstanding thermal stability. However, the origin of enhanced performance is not clear and seldom investigated until now. Here, a specific structured layered oxide (LiNi0.5Co0.2Mn0.3O2) consisting of concentration-gradient core, transition layer, and stable outer shell, is designed and achieved from double-shelled precursors to overcome the great challenge by comparison with the normal layered LiNi0.5Co0.2Mn0.3O2. As expected, the specific structured layered oxide displays excellent cycle life and thermal stability. After numerous cycles, the valence state of Ni and Co at normal layered oxide surface tends to a higher oxidation state than that of the specific structured oxide, and the spinel phase is observed on particle surface of normal layered oxide. Also, the deficient spinel/layered mixed phases lead to high surface film and charge-transfer resistance for normal layered oxide, whereas the specific structured one still remains a layered structure. Those results first illustrate the origin of improved electrochemical performance of layered core-shell and concentration-gradient cathode materials for lithium-ion batteries.

A stable Li-deficient oxide as high-performance cathode for advanced lithium-ion batteries.

Monodisperse Li-deficient Li(0.35)Ni(0.2)Co(0.1)Mn(0.7)O(2-x) spinel single crystals have been prepared for the first time. The Li-deficient oxide surprisingly delivers large reversible capacity (251.3 mA h g(-1)), outstanding cycle life and low median-voltage of 2.7 V in the range of 2.0-4.9 V. Importantly, high median-voltage (4.4 V) and superior rate capability are also obtained from 3.0 to 5.0 V. These results indicate that high-energy or high-power density can be achieved by controlling discharge cut-off voltage.

Effects on electrochemical performances for host material caused by structure change of modifying material.

High ionic conductive lithium niobium oxides were selected as the modifying material to investigate the effects on the electrochemical performances for host material LiNi1/3Co1/3Mn1/3O2 caused by the structure change of the modifying material at various calcination temperatures and modifying amounts. X-ray diffraction (XRD) studies revealed that the structure of the modifying material was single LiNbO3 phase after being calcined at 500 °C and changed to LiNbO3-Li3NbO4 mixture phases at 600 and 700 °C, and further changed to single Li3NbO4 phase at 800 °C. Electrochemical tests displayed that both LiNbO3 and Li3NbO4 phases of modifying material could contribute to the improvement of the cycle performances for the host material, but the improvement degree of Li3NbO4 phase was more evident. The cycle performances and high rate performances of the modified host material (calcined at 700 °C) electrodes were improved with the right modifying amount.

Zn(II)-PEG 300 globules as soft template for the synthesis of hexagonal ZnO micronuts by the hydrothermal reaction method.

Hexagonal ZnO micronuts (HZMNs) have been successfully synthesized with the assistance of poly(ethylene glycol) (PEG) 300 via a hydrothermal method. The structure and morphology of the HZMNs were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED). An individual ZnO micronut is revealed as twinned crystals. Time-dependent investigation shows that the growth of HZMNs involves a dissolution-recrystallization process followed by Ostwald ripening, in which is the first formed solid ZnO particles dissolve and transform to HZMNs with hollow structure. PEG 300 has been found to play a crucial role in the growth of this unique hollow structure. TEM observations show that the PEG chains aggregate to globules in water, which then have interaction with the dissolved zinc species to form the globules in a coiled state under hydrothermal conditions. These Zn(II)-PEG 300 globules act as soft template for the growth of HZMNs, and the possible growth mechanism is proposed. The room-temperature photoluminescence (PL) spectrum shows red emission around 612 nm with a full width at half-maximum (fwhm) only about 13 nm.
