RESUMO
Hematite has been considered as a promising photoanode candidate for photoelectrochemical (PEC) water oxidation and has attracted numerous interests in the past decades. However, intrinsic drawbacks drastically lower its photocatalytic activity. Ti-based modifications including Ti-doping, Fe2O3/Fe2TiO5 heterostructures, TiO2 passivation layers, and Ti-containing underlayers have shown great potential in enhancing the PEC conversion efficiency of hematite. Moreover, the combination of Ti-based modifications with various strategies towards more efficient hematite photoanodes has been widely investigated. Nevertheless, a corresponding comprehensive overview, especially with the most recent working mechanisms, is still lacking, limiting further improvement. In this respect, by summarizing the recent progress in Ti-modified hematite photoanodes, this review aims to demonstrate how the integration of titanium and iron atoms into hematite influences the PEC properties by tuning the carrier behaviours. It will provide more cues for the rational design of high-performance hematite photoanodes towards future practical applications.
RESUMO
PURPOSE: To evaluate the feasibility and practicability of Managing Cancer and Living Meaningfully (CALM) as a psychological intervention to reduce neutrophil to lymphocyte ratio (NLR), fear of cancer recurrence, general distress, and improve quality of life in lung cancer survivors. METHODS: Eighty lung cancer patients with FCRI severity subscale (≥13 points) were recruited and randomly assigned to CALM or usual care (UC). NLR was recorded before and after treatment. The Fear of Cancer Recurrence Inventory (FCRI), Quality of Life Questionnaire Core 30 (QLQ-C30) and Depression-Anxiety-Stress Scale (DASS-21) were used to evaluate patients at baseline (T0), immediately after treatment (T1), and at 2 (T2) and 4 (T3) months. RESULTS: Compared with UC, NLR was significantly different before and after CALM intervention (z=-5.498; P=0.000). There were significant differences in the scores of QLQ, FCR and general distress before and after the T1, T2 and T3 interventions (F=220.30, F=315.20, F=290.10, respectively; P<0.001). NLR was negatively correlated with QOL both before (r=-0.763; P<0.0001) and after the intervention (r=-0.810, P<0.0001). FCR and general distress were negatively correlated with QOL in CALM (T0: r=-0.726, r=-0.776, respectively; P<0.0001; T1: r=-0.664, r=-0.647, respectively; P<0.0001; T2: r=-0.678, r=-0.695, respectively; P<0.0001; T3: r=-0.511, P = 0.0008; r=-0.650, P<0.0001). CONCLUSION: CALM intervention can effectively reduce the NLR, alleviate the recurrence fear and general distress and improve the quality of life in patients. This study suggests that CALM may be an effective psychological intervention for reducing symptoms associated with lung cancer survivors.

Electrolysis of seawater can not only desalinate seawater but also produce high-purity hydrogen. Nevertheless, the presence of chloride ions in seawater will cause electrode corrosion and also undergo a chlorine oxidation reaction (ClOR) that competes with the oxygen evolution reaction (OER). Therefore, highly efficient and long-term stable electrocatalysts are needed in this field. In this work, an advanced bifunctional electrocatalyst based on NiFe layered double hydroxide (LDH)/FeOOH heterostructure nanosheets (NiFe LDH/FeOOH) was synthesized on nickel-iron foam (INF) via a simple electrodeposition method. The NiFe LDH/FeOOH electrode demonstrates excellent electrocatalytic activity and stability, which results from the strong interaction between FeOOH and NiFe LDH. Furthermore, ex situ X-ray photoelectron spectroscopy (XPS) and in situ Raman spectroscopy revealed the catalytic process and also demonstrated that the NiFe LDH/FeOOH heterostructure could facilitate the formation of active NiOOH species in the reaction. The obtained NiFe LDH/FeOOH catalyst displays low overpotentials of 181.8 mV at 10 mA·cm-2 for hydrogen evolution reaction (HER) and 286.2 mV at 100 mA·cm-2 for OER in the 1.0 M KOH + 0.5 M NaCl electrolyte. Furthermore, it also exhibits a low voltage of 1.55 V to achieve the current density of 10 mA·cm-2 and works steadily for 105 h at 100 mA·cm-2 for overall alkaline simulated seawater splitting. This work will afford a valid strategy for designing a non-noble metal catalyst for seawater splitting.
RESUMO
Vanadium oxides have been regarded as highly promising cathodes for aqueous zinc-ion batteries (ZIBs). However, obtaining high-performance vanadium oxide-based cathodes suitable for industrial application remains a significant challenge due to the need for cost-effective, straightforward, and efficient preparation methods. Herein, we present a facile and rapid synthesis of a composite cathode, consisting of layer-stacked VO2/V2O5 and graphene-like carbon nanosheets, in just 2.5 s by treating the commercial V2O5 powder via a flash Joule heating strategy. When employed as the cathode for ZIBs, the resulting composite delivers a comparable rate capacity of 459 mA h g-1 at 0.2 A g-1 and remarkable cycle stabilities of 355.5 mA h g-1 after 2500 cycles at 1.0 A g-1 and 169.5 mA h g-1 after 10,000 cycles at 10 A g-1, respectively. Further electrochemical analysis reveals that the impressive performance is attributed to the accelerated charge transfer and the alleviated structure degradation, facilitated by the abundant sites and a built-in electric field of the layer-stacked VO2/V2O5 heterostructure, as well as the excellent conductivity of graphene-like carbon nanosheets. This work introduces a unique approach for ultrafast and low-cost fabrication of high-performance vanadium oxide-based composite cathodes toward efficient ZIBs.
RESUMO
To evaluate the effectiveness and feasibility of managing cancer and living meaningfully (CALM), an intervention used to reduce the fear of cancer recurrence (FCR) in breast cancer survivors and improve their quality of life (QoL). A total of 103 breast cancer survivors were enrolled. Participants were randomly assigned to the CALM group or the care as usual (CAU) group. The participants completed a survey at baseline (T0) and after two (T1), four (T2), and six (T3) intervention sessions. The patients were assessed using the Cancer Worry Scale (CWS), Psychological Distress Thermometer (DT), Functional Assessment of Cancer Therapy-Breast (FACT-B) and Hospital Anxiety and Depression Scale (HADS). After the intervention, the CALM group showed a significant decrease in levels of FCR, distress, anxiety, and depression (χ2=154.353, χ2=130.292, χ2=148.879, and χ2=78.681; P<0.001, 0.001, 0.001, and 0.001, respectively) and an increased QoL (χ2=122.822, P<0.001). Compared with the CAU group, the CALM group showed significant differences in FCR, distress, QoL, anxiety and depression (F=292.431, F=344.156, F=11.115, F=45.124, and F=16.155; P<0.001, P<0.001, P=0.01, P<0.001, and P<0.001, respectively). Negative correlations were found between CWS and FACT-B scores in the CALM group (T0: r=-0.6345, P<0.001; T1: r=-0.4127, P=0.0017; T2: r=-0.2919, P=0.0306; and T3: r=-0.3188, P=0.0177) and in the CAU group (T0: r=-0.7714, P<0.0001; T1: r=-0.6549, P<0.0001; T2: r=-0.5060, P=0.0002; and T3: r=-0.3151, P=0.0291). Thus, the CALM intervention reduced FCR, distress, anxiety and depression in breast cancer survivors and improved QoL.
RESUMO
Objective: To evaluate the effectiveness and feasibility of Managing Cancer and Living Meaningfully based on VR (VR-CALM), which is used to manage expected symptoms of cancer itself, relieve psychological distress, and improve quality of life (QOL) in the Chinese breast cancer survivors (BCs). Methods: Ninety-eight patients with breast cancer were recruited in this study. These patients were randomly assigned to the VR-CALM group or the care as usual (CAU) group. All patients were evaluated by the Functional Assessment of Cancer Therapy-Breast cancer patient (FACT-B), Distress Thermometer (DT), Concerns About Recurrence Scale (CARS), Piper Fatigue Scale (PFS), Pittsburgh Sleep Quality Index (PSQI), The Self-Rating Anxiety Scale (SAS), and The Self-Rating Depression Scale (SDS) before and after VR-CALM or CAU application to BCs. We compared the differences in all these scores between the VR-CALM group and the control group. Results: Patients in the VR-CALM group showed a significant decrease in levels of distress, anxiety, depression, sleep disorders, and fatigue (t = -6.829, t = -5.819, t = -2.094, t = -3.031, t = -10.082, P ≤ 0.001, 0.001, 0.05, 0.01, 0.001, respectively) and had higher level of quality of life (t = 8.216, P ≤ 0.001) compared with the CAU group after intervention. And postintervention patients in VR-CALM group compared with preintervention showed lower level of distress and remarkable improvement of QOL (t = 11.521, t = -10.379, P ≤ 0.001, 0.001). The preintervention questionnaire revealed no significant between-group differences regarding distress, anxiety, depression, sleep disorders, fatigue, and quality of life. Conclusion: VR-CALM is a psychotherapy tailored to the needs of patients with breast cancer. This research innovatively used VR-based CALM intervention to improve psychological and chronic symptoms in BCs. The results of the present study indicate that VR-CALM has salutary effects on the improvement of QOL and relieves psychological distress, anxiety, depression, sleep disorders, and fatigue in BCs.
RESUMO
Background: The changes in inflammation and tumor biomarkers are associated with the anti-tumor immunological processes. Early detection and intervention are of great significance to the clinical management of cancer-related diseases. Peripheral blood biomarkers [e.g., neutrophil-to-lymphocyte ratio (NLR), carcinoembryonic antigen (CEA), and carbohydrate antigen 153 (CA153)] are obtained in real-timely, conveniently, and less invasively, and proved to availably predicted the disease states and prognosis of various cancers, including breast cancer (BC). Inflammation and poor disease management promote cognitive impairment. Chemotherapy-related cognitive impairment (CRCI) hazard long-term survival and quality of life (QOL) of BC patients, but its correlation with NLR, CEA, and CA153 is not clear. Purpose: This study aimed to investigate changes in NLR, CEA, and CA153 levels before and after chemotherapy and their correlation with CRCI in patients with early-stage BC. Materials and methods: The 187 patients with BC who were measured for NLR, CEA, and CA153 values within the first 24 hours of admission, were assigned into two groups: the before/after chemotherapy group (BCG/ACG). The ACG was assigned into two subgroups based on the cognitive assessment results: the cognitive normal/impaired group (CNG/CIG). Patients' self-perceived cognitive impairments were evaluated using a mini-mental state examination (MMSE), prospective and retrospective memory (PM and RM) questionnaire (PRMQ), and functional assessment of cancer therapy-cognitive function version 3 (FACT-Cog, version 3, including CogPCI, CogOth, CogPCA, and CogQOL). Their QOL was also evaluated. Results: The NLR and CA153 levels were elevated after chemotherapy (BCG vs ACG: Z = -1.996 and -1.615, P = 0.046 and 0.106, respectively), and significantly elevated in patients with CRCI (BCG vs CIG: Z = -2.444 and -2.293, P = 0.015 and 0.022; respectively). However, there was not reach significant difference in CEA levels between the four groups. In addition, there was a weak to moderate correlation between peripheral blood biomarkers (NLR, CEA, and CA153) levels and CRCI (r = -0.404, -0.205, -0.322; respectively; P < 0.001). Cognitive impairment scores (MMSE, PM, RM, and FACT-Cog) had a strong correlation with QOL in patients with early-stage BC (r = -0.786, 0.851, 0.849, and 0.938; respectively; P < 0.001). Conclusion: NLR and CA153 m be valuable diagnostic adjuncts of CRCI, and CRCI has a strong correlation with QOL in patients with early-stage BC.
