Clinical validation of the nursing outcome "Swallowing status: pharyngeal phase" in patients with laryngeal cancer.

AIMS AND OBJECTIVES: This study aimed to clinically validate the nursing outcome "Swallowing status: pharyngeal phase" (1013). METHODS: A two-stage study was designed: (1) Chinese translation and cultural adaptation and (2) clinical validation. Internal consistency and interrater reliability tests were performed on 285 patients with laryngeal cancer, and an additional 130 patients were randomly selected from the 285 patients as an independent sample. Criterion-related validity tests were performed using the standardized swallowing assessment (SSA). Nursing outcome sensitivity was detected by scoring two time points. RESULTS: The Cronbach's alpha coefficients were 0.951 for the nursing outcome and 0.942-0.965 for each indicator. The interclass correlation coefficient (ICC) values for each indicator ranged from 0.73 to 0.929. The scores of the nursing outcome were negatively correlated with the SSA scores (r = -0.555, p < 0.01). With the exception of two indicators, there was a significant difference (p < 0.05) between the total scores of the scale and its 11 indicator scores for the two time points. The results indicated that the nursing outcome "Swallowing status: pharyngeal phase" (1013) exhibited satisfactory psychometric properties and high sensitivity to change. CONCLUSIONS: The nursing outcome "Swallowing status: pharyngeal phase" (1013) demonstrated good reliability, validity, and sensitivity in patients with laryngeal cancer. IMPLICATIONS FOR NURSING PRACTICE: The nursing outcome "Swallowing status: pharyngeal phase" (1013) can be used to assess swallowing function in patients with laryngeal cancer and provide guidance for the development of rehabilitation intervention plans and nursing care.

Views of health care professionals on the implementation of preoperative advance care planning in older patients with head and neck cancer: Q methodology.

Objective: To investigate the views of health care professionals in a head and neck surgical department toward the implementation of advance care planning prior to surgery for older patients with head and neck cancer. Method: Q methodology was used to explore and analyze participants' views by combining quantitative and qualitative methods. Participants were asked to rank 35 Q statements generated via semi-structured interviews and a literature review and to explain the reasons for their ranking in subsequent interviews. The data was then analyzed and used to develop a factor series to illustrate participants' views. Results: This study surveyed 15 health care professionals, including eight doctors and seven nurses. The views of health care professionals toward preoperative implementation of advance care planning discussions were varied and could be categorized into three types: defending the autonomy of patients, patients' knowledge and the Chinese traditional cultural context hinder the implementation of preoperative advance care planning, and lack of confidence in performing preoperative advance care planning. Conclusions: Although the health care professionals in the head and neck surgical department in this study recognized the benefits of preoperative discussions regarding advance care planning, patients' knowledge level, traditional Chinese values, inadequate capacity among health care professionals, and unsound legal policies have caused these professionals to have misgivings about preoperative counseling and discussing advance care planning with patients. Further studies should be conducted, and strategies to overcome barriers to discussions of preoperative advance care planning should be developed.

The characteristics of H6 against Microcystis aeruginosa.

Algal bloom caused by Microcystis aeruginosa has always been the focus of attention; microbial algal control has the advantages of significant effect, low investment cost, and environmental friendliness; the use of microbial technology to inhibit the bloom has a broad prospect for development. In this study, a strain of Enterobacterium algicidal bacteria screened from a river was used to study the algicidal characteristics against Microcystis aeruginosa using SEM, 3-D EEM and zeta potential. The results showed that the optimal dosage (v/v) of the strain was 5% and the removal rate of algal cells was 70% after 7 days. When the algal density was OD680nm = 0.3, the removal rate of algal cells reached 83% after 7 days. In the pH range of 5 ~ 11, the removal rate of algal cells was 70 ~ 80% after 7 days. Algicidal bacteria H6 is mainly indirect algae lysis and is supplemented by direct algae lysis. Algicidal bacteria H6 removes algicidal substances by secreting high temperature resistant algicidal substances and algicidal products are humic acids. Algicidal bacterium H6 was a strain of Enterobacterium with good algicidal effect in a wide pH range, which enriched the bacterial resources in the control of cyanobacteria bloom in water. The high temperature resistance of the algae-soluble substance secreted by the algae-soluble substance provided convenience for the subsequent preparation and application of bacterial powder.

Diagnostic Value of Artificial Intelligence-Assistant Diagnostic System Combined With Contrast-Enhanced Ultrasound in Thyroid TI-RADS 4 Nodules.

OBJECTIVES: This study evaluated the diagnostic value of artificial intelligence-assistant diagnostic system combined with contrast-enhanced ultrasound in The American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS) 4 category thyroid nodules. METHODS: Thyroid nodules that were evaluated as ACR TI-RADS 4 by conventional ultrasound were selected, all of which had pathological or fine needle aspiration (FNA) results. All nodules were examined by contrast-enhanced ultrasound (CEUS) and artificial intelligence (AI) analysis. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of AI, CEUS and their combined diagnosis were compared; Analyzed and compared the diagnostic efficiency of AI, CEUS and their combined diagnosis. RESULTS: A total of 148 thyroid nodules were included in 140 patients, including 58 malignant nodules and 89 benign nodules. The sensitivity of combined diagnosis was significantly higher than that of AI or CEUS alone (P < .05). The NPV of AI, CEUS and combined diagnosis were statistically significant (P < .05). There was no significant difference in the diagnostic efficacy between AI and CEUS (P > .05), but there was a significant difference in NPV between AI and combined diagnosis (P < .05). The AUC of the combined diagnosis was 0.859, which was higher than that of AI, CEUS alone. CONCLUSIONS: AI has a high diagnostic efficiency, which was helpful for radiologists to make rapid assessment. AI combined CEUS can significantly improve the diagnostic sensitivity and NPV, which was beneficial for the early detection of malignant nodules.

Soil ammonium (NH4+) toxicity thresholds for restoration grass species.

Ionic rare earth mining has resulted in large amounts of bare soils, and revegetation success plays an important role in mine site rehabilitation and environmental management. However, the mining soils still maintain high NH4+ concentrations that inhibit plant growth and NH4+ toxicity thresholds for restoration plants have not been established. Here we investigated the NH4+ toxicological effects and provided toxicity thresholds for grasses (Lolium perenne L. and Medicago sativa L.) commonly used in restoration. The results show that high NH4+ concentration not only reduces the plant biomass and soluble sugars in leaves but also increases the H2O2 and MDA content, and SOD, POD, and GPX activities in roots. The SOD activities and root biomass can be adopted as the most NH4+ sensitive biomarkers. Six ecotoxicological endpoints (root biomass, soluble sugars, proline, H2O2, MDA, and GSH) of ryegrass, eight ecotoxicological endpoints (root biomass, soluble sugars, proline, MDA, SOD, POD, GPX, and GSH) of alfalfa were selected to determine the threshold concentrations. The toxicity thresholds of NH4+ concentrations were proposed as 171.9 (EC5), 207.8 (EC10), 286.6 (EC25), 382.3 (EC50) mg kg-1 for ryegrass and 171.9 (EC5), 193.2 (EC10), 234.7 (EC25), 289.6 (EC50) mg kg-1 for alfalfa. The toxicity thresholds and the relation between plant physiological indicators and NH4+ concentrations can be used to assess the suitability of the investigated plants for ecological restoration strategies.

Curcumin nicotinate decreases serum LDL cholesterol through LDL receptor-mediated mechanism.

Curcumin nicotinate (Curtn) is a synthesized ester derivative of curcumin and niacin. Our previous study has shown that Curtn lowers serum low-density lipoprotein cholesterol (LDL-C) levels in apoE-/- mice and promotes LDL-C uptake into HepG2 cells in vitro. The present study was to test the hypothesis that Curtn decreases serum LDL-C levels through decreased expression of pro-protein convertase subtilisin/kexin type 9 (PCSK9) and subsequent increase in LDL receptor expression. Male Wistar rats on high-fat diet (HFD) were treated with Curtn or rosuvastatin. Curtn or rosuvastatin treatment significantly decreased serum levels of total cholesterol (TC) and LDL-C in rats on HFD with increased liver LDL receptor expression. LDL-C-lowering effect of Curtn was not observed in LDL receptor deficient (LDLR-/-) mice on HFD, while rosuvastatin still decreased serum lipid levels in LDLR-/- mice, indicating that the reduction of serum LDL-C levels by Curtn treatment was LDL receptor-dependent. Curtn treatment also significantly decreased the protein expression of PCSK9 in Wistar rats and LDLR-/- mice. In HepG2 cells with overexpression of human PCSK9, Curtn treatment significantly increased LDL-C uptakes into hepatocytes, and increased LDL receptor distribution on cell surface in association with decreased PCSK9 protein expression. RNAi-LDLR significantly attenuated the effect of Curtn on LDLR distribution on cell surface. These data indicates that Curtn would decrease serum LDL-C level at least partially through inhibition of PCSK9 expression, and subsequent increase in LDL receptor expression and distribution in hepatocytes, serving as a potential novel compound to treat hyperlipidemia.

Effects of composite materials and revegetation on soil nutrients, chemical and microbial properties in rare earth tailings.

The mining of ionic rare earth elements in Ganzhou left large area of barren tailings with severe vegetation destruction in pressing needs of remediation. However, the remediating effects of soil additives combined with revegetation on the preservation of nutrients in the tailings and microbial communities were rarely studied. For this purpose, pilot experiments were implemented in a field, with the control group (CK) only cultivating plants without adding materials, and three treatments including peanut straw biochar composite (T1), phosphorus­magnesium composite (T2) and modified zeolite composite (T3) along with the cultivation of Medicago sativa L., Paspalum vaginatum Sw. and Lolium perenne L. Soil pH and organic matter in CK significantly decreased from 4.90 to 4.17 and from 6.62 g/kg to 3.87 g/kg after six months, respectively (p ≤ 0.05), while all the treatments could effectively buffer soil acidification (over 5.74) and delay the loss of soil organic matter. Soil cation exchange capacity was still below the detection limit in all the groups except T2. The results of rainfall runoff monitoring indicated that compared with CK, only T2 could significantly reduce the runoff loss of soil NO3- and SO42- by 45.61 %-75.78 % and 64.03 %-76.12 %, respectively (p ≤ 0.05). Compared with CK, the bacterial diversity in T2 and T3 significantly increased 21.18 % and 28.15 %, respectively (p ≤ 0.05), while T1 didn't change the bacterial or fungal diversity (p > 0.05). Co-occurrence network analysis showed that compared with CK, the whole microbial communities interacted more closely in the three treatments. Functional prediction of the microbial communities revealed all the treatments were dominated by carbon transforming bacteria and saprotrophic fungi except T2. This study demonstrated that the composite materials combined with revegetation couldn't retain soil nitrogen compounds and sulfate in rare earth tailings in the long term.

Genome-wide analysis of metallothionein gene family in maize to reveal its role in development and stress resistance to heavy metal.

BACKGROUND: Maize (Zea mays L.) is a widely cultivated cereal and has been used as an optimum heavy metal phytoremediation crop. Metallothionein (MT) proteins are small, cysteine-rich, proteins that play important roles in plant growth and development, and the regulation of stress response to heavy metals. However, the MT genes for maize have not been fully analyzed so far. METHODS: The putative ZmMT genes were identified by HMMER.The heat map of ZmMT genes spatial expression analysis was generated by using R with the log2 (FPKM + 1).The expression profiles of ZmMT genes under three kinds of heavy metal stresses were quantified by using qRT-PCR. The metallothionein proteins was aligned using MAFFT and phylogenetic analysis were constructed by ClustalX 2.1. The protein theoretical molecular weight and pI, subcellular localization, TFs binding sites, were predicted using ProtParam, PSORT, PlantTFDB, respectively. RESULTS: A total of 9 ZmMT genes were identified in the whole genome of maize. The results showed that eight of the nine ZmMT proteins contained one highly conserved metallothio_2 domain, while ZmMT4 contained a Metallothio_PEC domain. All the ZmMT proteins could be classified into three major groups and located on five chromosomes. The ZmMT promoters contain a large number of hormone regulatory elements and hormone-related transcription factor binding sites. The ZmMT genes exhibited spatiotemporal specific expression patterns in 23 tissues of maize development stages and showed the different expression patterns in response to Cu, Cd, and Pb heavy metal stresses. CONCLUSIONS: We identified the 9 ZmMT genes, and explored their conserved motif, tissue expression patterns, evolutionary relationship. The expression profiles of ZmMT genes under three kinds of heavy metal stresses (Cu, Cd, Pb) were analyzed. In summary, the expression of ZmMTs have poteintial to be regulated by hormones. The specific expression of ZmMTs in different tissues of maize and the response to different heavy metal stresses are revealed that the role of MT in plant growth and development, and stress resistance to heavy metals.

Cholesterol in LDL receptor recycling and degradation.

The SREBP2/LDLR pathway is sensitive to cholesterol content in the endoplasmic reticulum (ER), while membrane low-density lipoprotein receptor (LDLR) is influenced by sterol response element binding protein 2 (SREBP2), pro-protein convertase subtilisin/kexin type 9 (PCSK9) and inducible degrader of LDLR (IDOL). LDL-C, one of the risk factors in cardiovascular disease, is cleared through endocytosis recycling of LDLR. Therefore, we propose that a balance between LDLR endocytosis recycling and PCSK9-mediated and IDOL-mediated lysosomal LDLR degradation is responsible for cholesterol homeostasis in the ER. For statins that decrease serum LDL-C levels via cholesterol synthesis inhibition, the mechanism by which the statins increase the membrane LDLR may be regulated by cholesterol homeostasis in the ER.

SnS2 /Co3 S4 Hollow Nanocubes Anchored on S-Doped Graphene for Ultrafast and Stable Na-Ion Storage.

SnS2 has been widely studied as an anode material for sodium-ion batteries (SIBs) based on the high theoretical capacity and layered structure. Unfortunately, rapid capacity decay associated with volume variation during cycling limits practical application. Herein, SnS2 /Co3 S4 hollow nanocubes anchored on S-doped graphene are synthesized for the first time via coprecipitation and hydrothermal methods. When applied as the anode for SIBs, the sample delivers a distinguished charge specific capacity of 1141.8 mAh g-1 and there is no significant capacity decay (0.1 A g-1 for 50 cycles). When the rate is increased to 0.5 A g-1 , it presents 845.7 mAh g-1 after cycling 100 times. Furthermore, the composite also exhibits an ultrafast sodium storage capability where 392.9 mAh g-1 can be obtained at 10 A g-1 and the charging time is less than 3 min. The outstanding electrochemical properties can be ascribed to the enhancement of conductivity for the addition of S-doped graphene and the existence of p-n junctions in the SnS2 /Co3 S4 heterostructure. Moreover, the presence of mesopores between nanosheets can alleviate volume expansion during cycling as well as being beneficial for the migration of Na+ .

A novel recombinant peptide INSR-IgG4Fc (Yiminsu) restores insulin sensitivity in experimental insulin resistance models.

Type 2 diabetes mellitus (T2DM) is a chronic degenerative endocrine and metabolic disease with high mortality and morbidity, yet lacks effective therapeutics. We recently generated a novel fusion peptide INSR-IgG4Fc, Yiminsu (YMS), to facilitate the high-affinity binding and transportation of insulin. Thus, the aim of the present study was to determine whether the novel recombinant peptide, YMS, could contribute to restoring insulin sensitivity and glycaemic control in insulin resistance models and revealing its underlying mechanism. Palmitic acid (PA)-treated LO2 cells and high fat diet (HFD)-fed mice were treated with YMS. Therapeutic effects of YMS were measured using Western blotting, ELISA, qPCR, Histology and transmission electron microscopy. We observed that YMS treatment effectively improved insulin signaling in PA-treated LO2 cells and HFD-fed mice. Notably, YMS could significantly reduce serum levels of glucose, triglycerides, fatty acids and cholesterol without affecting the serum insulin levels. Moreover, our data demonstrated that YMS could restore glucose and lipid homeostasis via facilitating insulin transportation and reactivating PI3K/Akt signaling in both PA-treated cells and liver, gastrocnemius and brown fat of HFD-fed mice. Additionally, we noticed that the therapeutic effects of YMS was similar as rosiglitazone, a well-recognized insulin sensitizer. Our findings suggested that YMS is a potentially candidate for pharmacotherapy for metabolic disorders associated with insulin resistance, particularly in T2DM.

A novel fluorescence aptasensor for 8-hydroxy-2'-deoxyguanosine based on the conformational switching of K(+)-stabilized G-quadruplex.

A sensitive, lable-free and low cost fluorescence aptasensor was developed for detecting 8-hydroxy-2'-deoxyguanosine (8-OHdG) by using 8-OHdG aptamer (Apt) as a recognition probe and N-methyl mesoporphyrin IX (NMM) as a reporter. The method is based on the conformational switching of a K(+)-stabilized G-quadruplex to a 8-OHdG-stabilized one. NMM can selectively bind to K(+)-stabilized G-quadruplex instead of 8-OHdG-stabilized one. The addition of 8-OHdG in the solution of Apt - K(+) ions leads to a sharp change in fluorescence intensity, which showed a good linear response toward 8-OHdG concentration ranging from 3.96 nM to 211 nM with a detection limit of 1.19 nM. The relative standard deviation and the recovery were 1.23-3.26% (n=11) and 94.8-106.7%, respectively. The proposed aptasensor consists of only an aptamer probe and a specific dye NMM, avoiding the complex and expensive labeling procedure. Thus it is much cheaper and more applicable.

[Label-Free Resonance Light Scattering Detection of Hg²âº Based on Specific Structure Thymine-Hg²âº-Thymine].

A new label-free resonance light scattering method for the highly selective and sensitive detection of mercury ion was designed. This strategy makes use of the target-induced DNA conformational change to enhance the resonance light scattering intensity leading to an amplified optical signal. The Hg²âº ion, which possesses a unique property to bind specifically to two DNA thymine (T) bases, in the presence of Hg²âº, the specific oligonucleotide probes form a conformational reorganization of the oligonucleotide probes from single-chain structure to duplex-like complexes, which can greatly enhance the resonance light scattering intensity. Under the optimum experimental conditions, the enhanced resonance light scattering intensity at 566 nm was in proportion of mercury ion concentration in the range 7.2 x 10⁻9 x 10⁻8 mol · L⁻¹ with the linear regression equation was ΔI = 5.12c+3.55 (r = 0.999 5). This method was successfully applied to detection of Hg²âº in enviro nmental water samples, the RSD were less than 1.9% and recoveries were 99.4%-104.3%. This label-free strategy uses the mercury specific oligonucleotide probes as recognition elements and control the strength of resonance light scattering by changing the concentration of Hg²âº. It translating the small molecule detection into the DNA hybridization behavior leading to an amplified resonance light scattering signal can well enhance the sensitive detection of Hg²âº. With amplification by DNA hybridization behavior, the sensitivity for the detection of Hg²âº can achieve 2.16 x 10⁻9 mol · L(⁻¹). In this study, the stacked T-Hg²âº-Tfunctioned not only as amplification property but also as an selective recognition. The highly specific detection of Hg²âº is attributed to the formation of a stable T-Hg²âº-T complex.

Resonance light scattering determination of uranyl based on labeled DNAzyme-gold nanoparticle system.

A resonance light scattering (RLS) method has been developed using a uranyl (UO2(2+)) specific DNAzyme and gold nanoparticles (AuNPs). In this strategy, the cleavage of the substrate strand (SDNA) of DNAzyme results in releasing a shorter duplex in the presence of UO2(2+), leading to the aggregation of AuNPs and the increase of RLS intensity. The response signals linearly correlated with the concentration of UO2(2+) over the range of 1.36×10(-8)-1.50×10(-7) mol L(-1). The limit of detection (LOD) is 4.09×10(-9) mol L(-1). The method has excellent selectivity and higher sensitivity. It could provide a promising potential for the detection of metal ions, and be benefit to extend the application of RLS method.

Colorimetric detection of metallothioneins using a thymine-rich oligonucleotide-Hg complex and gold nanoparticles.

A simple and sensitive method for label-free, colorimetric detection of metallothioneins (MTs) has been developed by using a thymine (T)-rich oligonucleotide (TRO)-Hg-AuNP system. In this colorimetric strategy, the thiol groups of MTs could interact with mercury from the T-Hg(2+)-T complex to release TRO, resulting in a color change of the system. The response signals linearly correlated with the concentration of MTs over the range of 2.56 × 10(-8) to 3.08 × 10(-7) mol L(-1), and the limit of detection was 7.67 × 10(-9) mol L(-1). The relative standard deviation and the recovery were 2.3-4.8% (n = 11) and 94.2-103.9%, respectively. The proposed method avoids the label and derivatization steps in common methods, allows direct analysis of the samples by the naked eye without costly instruments, and is reliable, inexpensive, and sensitive.

A gold nanoparticles-modified aptamer beacon for urinary adenosine detection based on structure-switching/fluorescence-"turning on" mechanism.

A novel small molecule probe, aptamer beacon (AB), was introduced for adenosine (Ade) recognition and quantitative analysis. The Ade aptamer was engineered into an aptamer beacon by adding a gold nanoparticle-modified nucleotide sequence which is complementary to aptamer sequence (FDNA) at the 3'-end of FDNA. The fluorescence signal "turning on" was observed when AB was bound to Ade, which is attributed to a significant conformational change in AB from a FDNA/QDNA duplex to a FDNA-Ade complex. The Ade measurement was carried out in 20 mmol L(-1) Tris-HCl buffer solution of pH 7.4, ΔF signal linearly correlated with the concentration of Ade over the range of 2.0×10(-8) to 1.8×10(-6) mol L(-1). The limit of detection (LOD) for Ade is 6.0×10(-9) mol L(-1) with relative standard deviations (R.S.D) of 3.64-5.36%, and the recoveries were 98.6%, 100%, 102% (n=6), respectively. The present method has been successfully applied to determine Ade in human urine samples, and the obtained results were in good agreement with those obtained by the HPLC method. Our investigation shows that the unique properties of the AB could provide a promising potential for small molecules detection, and be benefit to extend the application of aptamer beacon technique.

Integrative management of commercialized wild mushroom: a case study of Thelephora ganbajun in Yunnan, southwest China.

The management of wild mushroom is interdisciplinary in nature, whereby the biophysical considerations have to be incorporated into the context of a wide range of social, economic and political concerns. However, to date, little documentation exists illustrating an interdisciplinary approach to management of wild mushrooms. Moreover, the empirical case studies necessary for developing applicable and practical methods are even more rare. This paper adopted an interdisciplinary approach combining participatory methods to improve the habitat management of Thelephora ganbajun, an endemic and one of the most economically valuable mushroom species in Southwest China. The paper documents an empirical case of how an interdisciplinary approach facilitated the development of a scientific basis for policy and management practice, and built the local capacity to create, adopt and sustain the new rules and techniques of mushroom management. With this integrative perspective, a sustainable management strategy was developed, which was found not only technically feasible for farmers, but also acceptable to the government from an ecological and policy-related perspective. More importantly, this approach has greatly contributed to raising the income of farmers. The paper highlights how the integration of biophysical and socioeconomic factors and different knowledge systems provided a holistic perspective to problem diagnosis and resolution, which helped to cope with conventional scientific dilemmas. Finally, it concludes that the success of this interdisciplinary approach is significant in the context of policy decentralization and reform for incorporating indigenous knowledge and local participation in forest management.
