A series of sheet-structured alkali metal uranyl oxalate hydrates: structures and IR spectra

Abstract The novel compounds K[(UO2)2(C2O4)2OH] · 2 H2O (KUrOx), Rb[(UO2)2(C2O4)2OH] · 2 H2O (RbUrOx), and Cs[(UO2)2(C2O4)2OH] · H2O (CsUrOx) have been synthesized by mild hydrothermal methods. Single crystal diffraction data collected at 125 K using MoKα radiation and a CCD-based area detector were used to solve and refine the crystal structures by full-matrix least-squares techniques to agreement indices (KUrOx, RbUrOx, CsUrOx) wR2 = 0.045, 0.062, 0.042 for all data, and R1 = 0.023, 0.030, 0.022 calculated for 1834, 1863, 1821 unique reflections respectively. The compounds KUrOx, RbUrOx, and CsUrOx are all monoclinic, space group P21/m, Z = 2. The unit cell of KUrOx has the dimensions a = 5.6427(4), b = 13.7123(9), c = 9.2669(6) Å, β = 98.7490(10)°, V = 708.68(8) Å3. The unit cell of RbUrOx has the dimensions a = 5.6225(4), b = 13.8339(9), c = 9.3308(6) Å, β = 98.1590(10)°, V = 718.41(8) Å3. The unit cell of CsUrOx has the dimensions a = 5.4688(3), b = 13.5710(8), c = 9.5408(5) Å, β = 97.5830(10)°, V = 701.90(7) Å3. The structures consist of chains of uranyl pentagonal bipyramids connected by oxalate groups and hydroxyl groups, and are isotypic with the compound NH4[(UO2)2(C2O4)2OH] · 2 H2O studied by Artem’eva et al. (2003); all four of these compounds are structurally composed of sheets made by polymerizing the chains of UO2C2O4(H2O) · 2 H2O (Jayadevan and Chackraburtty, 1972; Mikhailov et al., (1999), this being achieved by removing a H atom from an H2O group in the coordination sphere of the uranyl ion to form a hydroxyl vertex that is shared by two uranyl ions. Compensating positive charges are provided by the inclusion of large monovalent cations in channels that run through the sheets; these channels also contain hydrogen-bound H2O groups. The positions of the cations and H2O groups change in relation to the uranyl oxalate sheets and to each other through the series. The infrared spectra of these materials collected at room temperature are also presented and compared with previous work.

Experimental study of the ion current to a cylindrical Langmuir probe taking into account a finite ion temperature

This article deals with the experimental verification of a theoretical radial model, developed by the authors, for the sheath that surrounds a cylindrical Langmuir probe immersed in a plasma in which the positive ion temperature, Ti, is not negligibly small compared to the electron temperature, Te. The theoretical model is a generalization of the classical one developed for cold ions by Allen, Boyd, and Reynolds for the case of spherical probes, and extended by Chen for cylindrical ones. According to our theory, due to the positive ion thermal motion the ion current collected by the probe is increased with respect to the case of cold ions, so its influence must be considered in plasma diagnosis. An experimental device to accurately measure the I-V characteristic of a cylindrical probe in plasma, for which Ti/Te ≠ 0, has been developed. Very good agreement has been found between the theoretical positive ion I-V probe characteristic and the experimental values by using a Sonin plot.

Localization and Regulation of Claudin-14 in Experimental Models of Hypercalcemia.

Variations in the CLDN14 gene have been linked to increased risk of hypercalciuria and kidney stone formation. However, the exact cellular localization of CLDN14 and its regulation remain to be fully delineated. To this end, we generated a novel antibody that allowed the detection of CLDN14 in paraffin-embedded renal sections. This showed CLDN14 to be detectable in the kidney only after induction of hypercalcemia in rodent models. Protein expression in kidney is localized exclusively to the thick ascending limbs (TAL), mainly restricted to the cortical and upper medullary portion of the kidney. However not all cells in the TAL expressed the tight junction protein. In fact, CLDN14 was primarily expressed in cells also expressing CLDN16, but devoid of CLDN10. CLDN14 appeared in very superficial apical cell domains and near cell junctions in a belt-like formation along the apical cell periphery. In transgenic mice, Cldn14 promotor-driven LacZ activity did not show complete colocalization with CLDN14 protein nor was it increased by hypercalcemia, suggesting that LacZ activity cannot be used as a marker for CLDN14 localization and regulation in this model. In conclusion, CLDN14, showed a restricted localization pattern in the apical domain of select cells of the TAL.
Combined use of microwave ablation and cell immunotherapy induces nonspecific immunity of hepatocellular carcinoma model mice

ABSTRACT Microwave ablation (MWA) has been widely used in the treatment of solid tumors. Studies have been less conducted on the efficacy of MWA used with cell immunotherapy in treating hepatocellular carcinoma (HCC). The current study aimed at exploring the efficacy of MWA in combination with cell immunotherapy in treating HCC. Hepa1-6 HCC mice were treated by MWA, blockade, or the combined therapy (MWA used with blockade), or left untreated. Survival rates of the mice were plotted by Kaplan-Meier Curve, followed by log-rank test. 25 days after the operation, surviving mice were monitored for tumor recurrence, and tumor volumes were calculated every 5 days. Immunohistochemistry and flow cytometry were performed to detect the numbers of CD4+ and CD8+ cells in the tumors and spleens of mice. The expressions of related cytokines were detected and measured by ELISPOT and ELISA. The results showed that MWA combined with anti-PD-1/anti-CTLA-4 not only increased the survival time, protected the mice against tumor recurrence, but also enhanced the intratumoral infiltration of cytotoxic T lymphocyte and systemic T-cell immune responses induced by MWA through activation of synergistically specific antitumor immunity. In addition, the combined therapy increased T-helper 1 cell (Th1-type) cytokines, but reduced Th2-type cytokines, resulting in the polarization of Th1 cells. T-cell immune responses of HCC cells were activated by MWA. In addition, the combined therapy of MWA and anti-PD-1/anti-CTLA-4 induced Th1-type immune response, and showed specific antitumor immunity.
Low power design of block-based video codecs

Low Power Design of Block-Based Video Codecs The improving display resolution of new video appliances continuously increases the throughput requirements of video codecs and further complicates the challenges encountered during their cost-efficient design. In contrast, the energy and heat dissipation limitations of mobile appliances create the demand for low-power implementations. This PhD proposes a memory and communication centric design methodology to reach an energy efficient dedicated implementation. The high level steps of this design flow combine memory optimizations and algorithmic tuning on a sequential executable description. Then, a partitioning exploration introduces parallelism using a cyclo-static dataflow model. To maintain the effect of the high-level optimizations, also implementation specific aspects of communication channels, like using a kind of shared buffers, are expressed without extending the model of computation. Consequently, all analysis potential at design time is preserved. Towards dedicated hardware, these channels are implemented as a restricted, but sufficient set of communication primitives. They allow exploiting the principle of separation of communication and computation and lead to an automated RTL test and development strategy enabling rigorous functional testing. In this way, the design time is reduced. The introduced methodology is applied to the design of a high-performance MPEG-4 video encoder. The fully dedicated video pipeline exploits the inherent functional parallelism of the compression algorithm. It has a tailored memory hierarchy; uses burst accesses to external memory and supports realtime processing of 30 4CIF frames per second. The effect of the high-level optimizations on the power-efficiency is demonstrated through power simulations. The core consumes only 71 mW in a 180 nm, 1.62V UMC technology. This energy efficiency, achieved without using a low-power CMOS library, is equivalent to the state of the art for high resolution video encoders.

Effects of Implementing a Brief Family Nursing Intervention With Hospitalized Oncology Patients and Their Families in Germany: A Quasi-Experimental Study

Family nursing, based on the Calgary Family and Intervention Models, was implemented in a German oncological inpatient unit to promote effective family functioning in the context of cancer care. The objective of this study was to investigate the effects of implementing family nursing care on several psychological and physical outcomes of patients and their family members. A quasi-experimental study with 214 patients with a cancer diagnosis and 122 family members was conducted. Findings indicate that the superiority of family nursing, when compared to traditional care, could not be confirmed with respect to patients’ outcomes (psychological burden, social support, satisfaction with care) and family members’ outcomes (psychological burden, physical complaints, satisfaction with care). Various factors, such as country-specific structures and challenges in implementing family nursing care on an inpatient unit, may have contributed to these findings. Further replication attempts in similar settings in other countries are needed to shed light on the factors impairing or promoting the implementation of family nursing in practice settings.

A theoretical analysis of steady state δ13C profiles of soil organic matter

Soil organic matter (SOM) is the largest reservoir of terrestrial carbon and plays an important role in the global carbon cycle. Carbon isotope systematics of SOM have been widely used to constrain the dynamics of this important carbon reservoir though interpretation of carbon isotope data remains controversial. It has been widely observed that the 13C/12C ratio of SOM increases systematically with soil depth though there is little consensus as to which of several mechanisms may be responsible for this pattern. Here we present a process‐based theoretical model of steady state δ13CSOM versus depth profiles, which is coupled with a carbon concentration model. We show that widely observed δ13CSOM versus depth profiles can be modeled using a reasonable range of model parameters. More importantly, we show that coupling carbon isotope data with carbon concentrations in soils allows for tighter constraints on model parameters that have biological and environmental significance.
Urban foci of murine typhus involving cat fleas (Ctenocephalides felis felis) collected from opossums in Mexico City

Murine typhus, a neglected rickettsiosis caused by Rickettsia typhi, is a common disease in several Latin‐American countries. The sylvatic life cycle of R. typhi encompasses the presence of several wild mammals, particularly opossums of the genus Didelphis and their associated fleas. Due to the colonization of wild environments by human populations, the increase in contact with opossum fleas has generated the presence of urban outbreaks of typhus. For this reason, the aim of our study was to identify the presence and diversity of Rickettsia sp. in fleas collected from opossums of an urban reserve in Mexico City. Opossums were captured from February to September 2017. For the detection of Rickettsia DNA, fragments of 800 bp of the citrate synthase (gltA) and the outer membrane protein B (ompB) were amplified. A total of 141 fleas (111 ♀, 30 ♂) of a single species (Ctenocephalides felis felis) were recovered from 31 Didelphis virginiana. Rickettsia DNA was detected in 17.7% (25/141) of the analysed fleas, recovered from seven infested opossums. The Maximum likelihood of sequences exhibited an identity of 99%–100% with sequences of R. typhi from southern United States. This work represents the first record of R. typhi in fleas from opossums in Mexico.
DNMT1-mediated lncRNA MEG3 methylation accelerates endothelial-mesenchymal transition in diabetic retinopathy through the PI3K/AKT/mTOR signaling pathway.

Diabetic retinopathy (DR) is one of the serious complications that occur in diabetic patients that frequently causes blindness. Long non-coding RNAs (lncRNAs) have been associated with DR pathology. This study aimed to determine the underlying mechanism of lncRNA maternally expressed gene 3 (MEG3) in association with DNA methyltransferase 1 (DNMT1) in the endothelial-mesenchymal transition (endMT) that occurs in DR. A rat model of DR was induced by streptozotocin (STZ) injection, and high glucose (HG)-induced cell model was established by exposing microvascular endothelial cells obtained from retina of rats to HG. Subsequently, MEG3 was overexpressed in rat and cell models to characterize its impact on endMT in DR and the involvement of the PI3K/AKT/mTOR signaling pathway. Furthermore, the methylation level of MEG3 promoter region was determined with the application of methylation-specific polymerase chain reaction, followed by Chromatin immunoprecipitation assay for methyltransferase enrichment. Finally, we examined the regulation of DNMT1 on MEG3 methylation and endMT in the HG-induced cell model. The results obtained revealed downregulated MEG3 expression in DR rat and cell models. Overexpressed MEG3 was shown to suppress endMT in DR rat and cell models through the inhibition of the PI3K/AKT/mTOR signaling pathway. Notably, DNMT1 could promote MEG3 promoter methylation to inhibit MEG3 expression by recruiting methyltransferase, which activated the PI3K/AKT/mTOR signaling pathway to accelerate endMT in DR. These findings further highlighted the inhibitory effect of MEG3 on endMT in DR, thus presenting a novel therapeutic target candidate for DR treatment.
Are Nursing Interventions Effective in Improving Quality of Life in Cancer Survivors? A Systematic Review

Background Cancer survivors (CSs) have needs that can negatively impact their quality of life (QoL). Oncology nurses play a key role in providing comprehensive care in cancer survivorship, although little is known about their impact on health outcomes. Objective The aim of this study was to determine the effectiveness of nursing interventions to improve QoL and satisfaction with care of CSs. Methods A systematic review was conducted. PubMed, CINAHL, PsycINFO, and Cochrane databases were searched for experimental studies. The Joanna Briggs Institute Checklist for Randomized Controlled Trials was used to verify the quality of the studies (Prospero reference: CRD42020148294). Results Of the 8 clinical trials eligible for inclusion, 5 demonstrated that interventions conducted by nurses improved the overall QoL or some of its domains in CSs. The included studies focused on short-term survival; no studies in long-term CSs were identified. Two studies assessed satisfaction with care of survivors, obtaining positive results. Conclusions Nursing interventions seem to improve the QoL of short-term CSs. However, because of the low number of studies identified, the findings of this systematic review should be interpreted with caution. Implications for practice Further studies are necessary to strengthen the implementation of effective nursing intervention in cancer practice. Research should particularly be conducted with long-term CSs as there is lack of data on this specific stage of cancer.
Changes in empathy of nurses from 2009 to 2018: A cross-temporal meta-analysis

The empathy of nurses is associated with self-care and self-compassion, which may enhance the quality of the nurse-patient relationship. Yet, research on the empathy of nursing staff has mostly used cross-sectional designs, which cannot capture the degree of empathy changes over time. To explore changes in empathy among nurses in China from 2009 to 2018. A cross-temporal meta-analysis was used to examine continuous changes in the empathy of nurses. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to conduct this cross-temporal meta-analysis of 57 samples of nurses in China who completed the three subscales (perspective-taking, compassionate care, and walking in the patient’s shoes) of the Jefferson Scale of Empathy-Health Professionals from 2009 to 2018 (N = 13,825). This meta-analysis was conducted following good scientific practice in every phase, and approval by ethics committees was not required according to the local regulations in China. The findings suggest that the nurses’ mean total scores of empathy and perspective-taking on the Jefferson Scale of Empathy-Health Professionals declined significantly over time, but the trend in compassionate care and walking in the patient’s shoes was not significant. No significant changes were found in the overall empathy or the three dimensions of empathy of the nurses in the Eastern region across time, whereas a significant decline was found on the total empathy and perspective-taking scores of the nurses in other regions (i.e. the Central and Western regions). The mean total score of empathy and walking in the patient’s shoes of the nurses who worked in the intensive care units showed a significant decrease over time. Furthermore, these findings indicate that the empathy of Chinese nurses has decreased steadily over the past 10 years. High levels of empathy can effectively reduce healthcare risks, errors, and disputes among nursing staff and enhance patient satisfaction and well-being.
Optimal choice of antiseizure medication: Agreement among experts and validation of a web‐based decision support application

Optimal choice of antiseizure medication (ASM) depends on seizure type, syndrome, age, gender, comorbidities and co‐medications. There are no fixed rules on how to weigh these factors; choices are subjective and experience‐driven. We investigated agreement among experts in selecting ASM as monotherapy and used their prevailing choices to validate a web‐based decision‐support application.
Agave Americana L. leaves: Effect of the water-soluble carbohydrate extract on the textural properties of pectin gel

Hydrocolloid from leaves of Agave Americana was extracted with distilled water. In The present study, the chemical composition of leaves and its water soluble extract (WSCE) of Agave Americana was determined. The yield of the hydrocolloid was 55% (w/w) based on dry material. The contents of total dietary fibre total sugars, protein, lipid and ash of Agave leaves were 42.56%, 40.02%, 22.71%, 4.66% and 1.21%, respectively. The WSCE was exhibited the highest levels of soluble sugars and lower levels of soluble fibre than the Agave leaves (66.08% against 18.25% and 6.45 % against 9.28%, respectively) with a potential food application. The mixed gel texture at pectin concentration of 1, 2, 3, 4 and 5 % (W/W) and WSCE concentration 4% (w/v) was investigated. Then it was found that the WSCE exhibited a synergetic effect with pectin in relation to gel strength. The maximum of synergistic effect was observed at the 4% pectin concentration of pectin-WSCE gels. The obtained WSCE-pectin gels have a higher firmness and elasticity compared with the pectin gels. These results open a good alternative to obtain value added products from this resource.
