Metal free C-O bond cleavage: a new strategy for the synthesis of substituted oxazoles.

A strategy for the efficient metal-free C-O bond cleavage of ester using amines for the synthesis of substituted oxazoles was developed for the first time. The synthesis proceeded smoothly under metal-free conditions, combining C-O bond cleavage as well as C-N and C-O bond formation in one pot to yield desired products in moderate to excellent yields, and accommodated a wide range of functional groups and substrates.

Spontaneous dislodgment of a peritoneal dialysis catheter inserted using the Seldinger technique: A case report.

BACKGROUND: Peritoneal dialysis (PD) is an important renal replacement therapy in patients with end-stage renal disease. PD catheters remain the lifeline for patients undergoing PD. The catheter technique survival rate is considered a core PD outcome domain. CASE SUMMARY: The PD catheter spontaneously dislodged in a patient undergoing PD during regular fluid exchange without pain. Abdominal computed tomography showed a tunnel infection. A double-cuff straight Tenckhoff catheter had been inserted using the Seldinger technique. Before this incident, the patient had a history of tunnel infections. We speculate that recurrent tunnel infections and catheter insertion using the Seldinger technique may have led to catheter dislodgement. CONCLUSION: The present case suggests that clinicians should more rigorously assess the persistence of catheter-related infections concerning the potential complications arising from catheter dislodgement associated with the Seldinger technique.

Adverse renal outcomes following targeted therapies in renal cell carcinoma: a systematic review and meta-analysis.

Introduction: To clarify the prevalence of adverse renal outcomes following targeted therapies in renal cell carcinoma (RCC). Methods: A systematic search was performed in MEDLINE, EMBASE, and Cochrane Central Library. Studies that had reported adverse renal outcomes following targeted therapies in RCC were eligible. Outcomes included adverse renal outcomes defined as either renal dysfunction as evidenced by elevated serum creatinine levels or the diagnosis of acute kidney injury, or proteinuria as indicated by abnormal urine findings. The risk of bias was assessed according to Cochrane handbook guidelines. Publication bias was assessed using Funnel plot analysis and Egger Test. Results: The occurrences of the examined outcomes, along with their corresponding 95% confidence intervals (CIs), were combined using a random-effects model. In all, 23 studies including 10 RCTs and 13 observational cohort studies were included. The pooled incidence of renal dysfunction and proteinuria following targeted therapies in RCC were 17% (95% CI: 12%-22%; I2 = 88.5%, p < 0.01) and 29% (95% CI: 21%-38%; I2 = 93.2%, p < 0.01), respectively. The pooled incidence of both types of adverse events varied substantially across different regimens. Occurrence is more often in polytherapy compared to monotherapy. The majority of adverse events were rated as CTCAE grades 1 or 2 events. Four studies were assessed as having low risk of bias. Conclusion: Adverse renal outcomes reflected by renal dysfunction and proteinuria following targeted therapies in RCC are not uncommon and are more often observed in polytherapy compared to monotherapy. The majority of the adverse events were of mild severity. Systematic Review Registration: Identifier CRD42023441979.

Vitamin D Relieves Epilepsy Symptoms and Neuroinflammation in Juvenile Mice by Activating the mTOR Signaling Pathway via RAF1: Insights from Network Pharmacology and Molecular Docking Studies.

Epilepsy is a common neurological disorder, and the exploration of potential therapeutic drugs for its treatment is still ongoing. Vitamin D has emerged as a promising treatment due to its potential neuroprotective effects and anti-epileptic properties. This study aimed to investigate the effects of vitamin D on epilepsy and neuroinflammation in juvenile mice using network pharmacology and molecular docking, with a focus on the mammalian target of rapamycin (mTOR) signaling pathway. Experimental mouse models of epilepsy were established through intraperitoneal injection of pilocarpine, and in vitro injury models of hippocampal neurons were induced by glutamate (Glu) stimulation. The anti-epileptic effects of vitamin D were evaluated both in vivo and in vitro. Network pharmacology and molecular docking analysis were used to identify potential targets and regulatory pathways of vitamin D in epilepsy. The involvement of the mTOR signaling pathway in the regulation of mouse epilepsy by vitamin D was validated using rapamycin (RAPA). The levels of inflammatory cytokines (TNF-α, IL-1ß, and IL-6) were assessed by enzyme-linked immunosorbent assay (ELISA). Gene and protein expressions were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) staining was used to analyze the apoptosis of hippocampal neurons. In in vivo experiments, vitamin D reduced the Racine scores of epileptic mice, prolonged the latency of epilepsy, and inhibited the production of TNF-α, IL-1ß, and IL-6 in the hippocampus. Furthermore, network pharmacology analysis identified RAF1 as a potential target of vitamin D in epilepsy, which was further confirmed by molecular docking analysis. Additionally, the mTOR signaling pathway was found to be involved in the regulation of mouse epilepsy by vitamin D. In in vitro experiments, Glu stimulation upregulated the expressions of RAF1 and LC3II/LC3I, inhibited mTOR phosphorylation, and induced neuronal apoptosis. Mechanistically, vitamin D activated the mTOR signaling pathway and alleviated mouse epilepsy via RAF1, while the use of the pathway inhibitor RAPA reversed this effect. Vitamin D alleviated epilepsy symptoms and neuroinflammation in juvenile mice by activating the mTOR signaling pathway via RAF1. These findings provided new insights into the molecular mechanisms underlying the anti-epileptic effects of vitamin D and further supported its use as an adjunctive therapy for existing anti-epileptic drugs.

Integration of metabolomics and transcriptomics reveals the regulation mechanism of the phenylpropanoid biosynthesis pathway in insect resistance traits in Solanum habrochaites.

Solanum habrochaites (SH), a wild species closely related to 'Ailsa Craig' (AC), is an important germplasm resource for modern tomato breeding. Trichomes, developed from epidermal cells, have a role in defense against insect attack, and their secretions are of non-negligible value. Here, we found that the glandular heads of type VI trichomes were clearly distinguishable between AC and SH under cryo-scanning electron microscopy, the difference indicating that SH could secrete more anti-insect metabolites than AC. Pest preference experiments showed that aphids and mites preferred to feed near AC compared with SH. Integration analysis of transcriptomics and metabolomics data revealed that the phenylpropanoid biosynthesis pathway was an important secondary metabolic pathway in plants, and SH secreted larger amounts of phenylpropanoids and flavonoids than AC by upregulating the expression of relevant genes in this pathway, and this may contribute to the greater resistance of SH to phytophagous insects. Notably, virus-induced silencing of Sl4CLL6 not only decreased the expression of genes downstream of the phenylpropanoid biosynthesis pathway (SlHCT, SlCAD, and SlCHI), but also reduced resistance to mites in tomato. These findings provided new genetic resources for the synthesis of phenylpropanoid compounds and anti-insect breeding in S. habrochaites and a new theoretical basis for the improvement of important traits in cultivated tomato.

Fine Mapping and Identification of a Candidate Gene for the Glossy Green Trait in Cabbage (Brassica oleracea var. capitata).

In higher plants, cuticular wax deposited on the surface of epidermal cells plays an important role in protecting the plant from biotic and abiotic stresses; however, the molecular mechanism of cuticular wax production is not completely understood. In this study, we identified a glossy green mutant (98-1030gl) from the glaucous cabbage inbred line 98-1030. Scanning electron microscopy indicated that the amount of leaf cuticular wax significantly decreased in 98-1030gl. Genetic analysis showed that the glossy green trait was controlled by a single recessive gene. Bulked segregant analysis coupled with whole genome sequencing revealed that the candidate gene for the glossy green trait was located at 13,860,000-25,070,000 bp (11.21 Mb) on Chromosome 5. Based on the resequencing data of two parents and the F2 population, insertion-deletion markers were developed and used to reduce the candidate mapping region. The candidate gene (Bol026949) was then mapped in a 50.97 kb interval. Bol026949 belongs to the Agenet/Tudor domain protein family, whose members are predicted to be involved in chromatin remodeling and RNA transcription. Sequence analysis showed that a single nucleotide polymorphism mutation (C → G) in the second exon of Bol026949 could result in the premature termination of its protein translation in 98-1030gl. Phylogenetic analysis showed that Bol026949 is relatively conserved in cruciferous plants. Transcriptome profiling indicated that Bol026949 might participate in cuticular wax production by regulating the transcript levels of genes involved in the post-translational cellular process and phytohormone signaling. Our findings provide an important clue for dissecting the regulatory mechanisms of cuticular wax production in cruciferous crops.

Decision models of emission reduction considering CSR under reward-penalty policy.

For the two emission reduction technologies of clean process (CT Mode) and end-of-pipe pollution control technology (ET Mode), this paper constructs production and low-carbon R&D decision-making models considering consumers' green preference, and discusses the impact of social responsibility on firm's decision-making, profit and social welfare. Then, the difference of optimal decision, profit and social welfare is analyzed when the firm adopt two emission reduction technologies with or without reward-penalty policy. The main conclusions of this paper are as follows: (1) Whether using clean process technology or end-of-pipe pollution control technology, consumers' green preference behavior can increase corporate profit. When consumers' green preference is small, consumers' green preference is negatively correlated with social welfare. When consumers' green preference is large, consumers' green preference is positively correlated with social welfare. (2) Corporate social responsibility is conducive to improving the level of social welfare, not conducive to the increase of corporate profits. (3) When the reward and punishment intensity is small, the reward-penalty policy cannot effectively motivate the firm to assume social responsibility. Only when the reward and punishment reaches a certain level, the mechanism can have an incentive effect on the firm, and the government can actively implement the mechanism. (4) When the market scale is small, the adoption of end-of-pipe pollution control technology is more beneficial to the firm; When the market scale is large, it is beneficial for the firm to adopt clean technology. (5) If the efficiency of end-of-pipe pollution control and emission reduction is much higher than that of clean process, the firm should choose end-of-pipe pollution control technology, otherwise choose clean process.

Collaborative innovation evolution of the logistics and manufacturing industry in China.

The logistics industry and the manufacturing industry are mutually productive factors and service objects, which determines that the two must develop cooperatively. In the increasingly fierce market competition, open collaborative innovation is more conducive to improving the level of linkage between the logistics industry and the manufacturing industry, and promoting industrial development. Based on the patent data of 284 prefecture-level cities in China from 2006 to 2020, this paper uses Gis spatial analysis, spatial Dubin model and other methods to analyze the collaborative innovation between the logistics industry and manufacturing industry. The results lead to several conclusions. (i) The overall collaborative innovation level is not high, and in terms of the evolution cycle, collaborative innovation has experienced three stages: embryo, rapid development and stable development. (ii) The spatial agglomeration characteristics of the collaborative innovation between the two industries are more and more obvious, and the Yangtze River Delta urban agglomeration and the middle reaches of the Yangtze River urban agglomeration play an important role in the collaborative innovation between the two industries. (iii) The hot spots of collaborative innovation between the two industries are concentrated in the eastern and northern coastal areas, while the cold spots are concentrated in the south of the northwest and southwest areas in the late stage of the study. (iiii) The positive influencing factors of local collaborative innovation between the two industries include economic development, scientific and technological level, government behavior, and employment, while the negative influencing factors include information technology level, and logistics infrastructure. Economic development has a negative spatial spillover effect on surrounding areas, while the spatial spillover effect of scientific and technological level is significantly positive. This article aims to explore the current situation and influencing factors of collaborative innovation between the two industries, with a view to proposing countermeasures and suggestions for improving the level of collaborative innovation between the two industries, and also providing new ideas for research on cross industry collaborative innovation.

Competitive advantage, relationship, and benefit: Primary and secondary influencing factors of supply chain collaboration in China's advanced manufacturing industry.

The advanced manufacturing industry is located at the top of the manufacturing value chain. Its development is restricted by supply chain collaboration (SCC), the level of which is affected by many factors. Few studies comprehensively summarize what influences SCC and distinguish the impact level of each factor. Practitioners have difficulty isolating the primary factors that affect SCC and managing them effectively. Therefore, based on synergetics and the theory of comparative advantage, this study analyzes what influences SCC in the advanced manufacturing industry and how these influencing factors work, using data from 94 manufacturing enterprises and the Haken model to identify the influencing factors. The results show that China's advanced manufacturing supply chain underwent a phase change and entered a new stage during 2017-2018. In the new stage, the competitive advantages of enterprises are one order parameter (slow variable) and are primary factors affecting SCC. The interest demands of enterprises are a fast variable and are secondary factors affecting SCC. The competitive advantages of enterprises dominate the interests of enterprises in affecting the collaboration level of China's advanced manufacturing supply chain. In addition, in the process of influencing SCC, there is a positive correlation between the competitive advantages of enterprises and the interest demands of enterprises, and the two factors have a positive feedback mechanism. Finally, when the enterprises in the supply chain cooperate based on their differential advantages, the collaboration capability of the supply chain is at the highest level, and the overall operation of the supply chain is orderly. In terms of theoretical contribution, this study is the first to propose a collaborative motivation framework that conforms to the characteristics of sequential parameters, which provides a theoretical reference for subsequent studies on SCC. In addition, the theory of comparative advantage and synergetics are linked for the first time in this study, and both of them are enriched and developed. Equally importantly, this study compares the bidirectional influence between firms' competitive advantages and firms' interest demands and the ability of both to influence SCC, enriching previous validation studies of unidirectional influence. In terms of practical implications, this study guides top managers to focus on the management practice of collaborative innovation in the supply chain and advises purchasing managers and sales managers on selecting supply chain partnerships.

Correction to: Evaluation of salinity resistance and combining ability analysis in the seedlings of mulberry hybrids (Morus alba L.).

[This corrects the article DOI: 10.1007/s12298-023-01304-w.].

Evaluation of salinity resistance and combining ability analysis in the seedlings of mulberry hybrids (Morus alba L.).

Soil salinization has become one of the major abiotic stresses influencing food security and maintenance of sustainable eco-environment. Highly salt-tolerant germplasm in mulberry, an important perennial woody plant, could restore the ecology and increase the agricultural income. Studies on the salt tolerance of mulberry are limited. Therefore, the aim of this study was to estimate the genetic variation and develop a reliable and effective evaluation of salt tolerance in 14 F1 mulberry hybrids that were directionally constructed using nine genotypes, including two females and seven males. A salt stress test was performed using 0.3%, 0.6%, and 0.9% (w/v) NaCl to investigate four morphological indexes of the growth rate: the shoot height (SHR), leaf number (LNR), leaf area (LAR), and the total weight of the whole plant after defoliation (BI) in the seedlings of the 14 combinations. The most suitable concentration for evaluating salt tolerance was identified as 0.9% NaCl based on the changes in the salt tolerance coefficient (STC). Comprehensive evaluation (D) values were obtained using principal components and membership functions based on four morphological indexes and their STCs, grouped into three principal component indexes cumulatively contributing to approximately 88.90% of the total variance. Two highly salt-tolerant, three moderately salt-tolerant, five salt-sensitive, and four highly salt-sensitive genotypes were screened. Anshen × Xinghainei and Anshen × Xinghaiwai had the highest D values. The analyses of combining ability further showed that the variances for LNR, LAR, and BI were elevated significantly with the increasing NaCl concentrations. Anshen × Xinghainei from two superior parents (female: Anshen, male: Xinghainei) with relatively higher general combing abilities for SHR, LAR, and BI was the best hybrid combination under high salinity stress, and presented the best specific combining ability for BI. Of all the traits tested, LAR and BI were greatly affected by additive effects and might be the two most reliable indexes. These traits show higher correlation with the salt tolerance of mulberry germplasm at the seedling stage. These results may enrich the mulberry resources by breeding and screening for elite germplasms with high salt tolerance.

Genome-Wide Identification of the U-Box E3 Ubiquitin Ligase Gene Family in Cabbage (Brassica oleracea var. capitata) and Its Expression Analysis in Response to Cold Stress and Pathogen Infection.

Plant U-box E3 ubiquitin ligases (PUBs) play an important role in growth, development, and stress responses in many species. However, the characteristics of U-box E3 ubiquitin ligase genes in cabbage (Brassica oleracea var. capitata) are still unclear. Here, we carry out the genome-wide analysis of U-box E3 ubiquitin ligase genes in cabbage and identify 65 Brassica oleracea var. capitata U-box E3 ubiquitin ligase (BoPUB) genes in the cabbage genome. Phylogenetic analysis indicates that all 65 BoPUB genes are grouped into six subfamilies, whose members are relatively conserved in the protein domain and exon-intron structure. Chromosomal localization and synteny analyses show that segmental and tandem duplication events contribute to the expansion of the U-box E3 ubiquitin ligase gene family in cabbage. Protein interaction prediction presents that heterodimerization may occur in BoPUB proteins. In silico promoter analysis and spatio-temporal expression profiling of BoPUB genes reveal their involvement in light response, phytohormone response, and growth and development. Furthermore, we find that BoPUB genes participate in the biosynthesis of cuticular wax and in response to cold stress and pathogenic attack. Our findings provide a deep insight into the U-box E3 ubiquitin ligase gene family in cabbage and lay a foundation for the further functional analysis of BoPUB genes in different biological processes.

Microbiome - based agents can optimize composting of agricultural wastes by modifying microbial communities.

Microorganisms that facilitate the decomposition of agricultural wastes are of importance during composting processes. Here, we assessed if microbial agents, comprising Clonostachys rosea, Bacillus amylolyticus and Rhodospirillum photometricum can facilitate the decomposition of a compost mix of vegetable waste, chicken manure, sawdust, and biochar. The results showed that inoculating the compost mix with the microbial agents elevated the compost temperature, increased the thermophilic period, and enhanced cellulose degradation. Microbial agent inoculation also changed the diversity and richness of decomposing microbial communities. Among the microbial agents, the mixture of C. rosea and B. amylolyticus performed better than other mixtures. Taken together, the results confirmed that the microbial agents comprising C. rosea can enhance the composting process by ameliorating the physiochemical conditions of agricultural wastes and promoting the diversity and proliferation of beneficial bacteria involved in the decomposition of cellulose.

Escaping drought: The pectin methylesterase inhibitor gene Slpmei27 can significantly change drought resistance in tomato.

Drought stress will lead to a decrease in tomato yield and poor flavour, yield and quality, resulting in economic losses in agricultural production. Mining the key genes regulating tomato drought resistance is of great significance to improve the drought resistance of tomato plants. The cell wall can directly participate in the plant drought stress response as one of the main components of the cell wall, and the regulation of pectin content in plant drought resistance is still unclear. Here, the candidate gene Solyc08g006690 (Slpmei27) was obtained by fine mapping based on genome sequencing technology (BSA-seq) of late-maturing stress-resistant tomato mutants found in the field. Slpmei27 is expressed in the cell wall. The transient silencing of Slpmei27 by VIGS significantly improved the drought resistance of tomato. Meanwhile, Slpmei27 silencing could significantly change the cell wall structure of plants, change the stomatal pass rate, reduce the water loss rate of plants, improve the scavenging ability of reactive oxygen species, change the redox balance in plants, and thus improve the drought resistance of tomato. The promoter region of this gene contains a large number of hormone-response and stress-response binding sites. The promoter region of the Slpmei27 gene in the mutant could lower the expression of downstream genes. Through this study, the mechanism by which Slpmei27 improves tomato drought resistance was revealed, and the relationship between pectin methyl ester metabolism and plant drought resistance was established, providing a theoretical basis for the production of high-quality tomato materials with high drought resistance.

Slym1 control the color etiolation of leaves by facilitating the decomposition of chlorophyll in tomato.

Photosynthesis, as an important biological process of plants, produces organic substances for plant growth and development. Although the molecular mechanisms of photosynthesis had been well investigated, the relationship between chlorophyll synthesis and photosynthesis remains largely unknown. The leaf-color mutant was an ideal material for studying photosynthesis and chlorophyll synthesis, which had been seldom investigated in tomato. Here, we obtained a yellow leaf tomato mutant ym (The mutant plants from the line of zs4) in field. Transmission electron microscopy (TEM) and photosynthetic parameters results demonstrated that chloroplast's structure was obviously destroyed and photosynthetic capacity gets weak. The mutant was hybridized with the control to construct the F2 segregation population for sequencing. Slym1 gene, controlling yellow mutant trait, was identified using Bulked Segregation Analysis. Slym1 was up-regulated in the mutant and Slym1 was located in the nucleus. The genes associated with photosynthesis and chlorophyll synthesis were down-regulated in Slym1-OE transgenic tomato plants. The results suggested that Slym1 negatively regulate photosynthesis. Photosynthetic pigment synthesis related genes HEMA, HEMB1, CHLG and CAO were up-regulated in Slym1 silencing plants. The redundant Slym1 binding the intermediate proteins MP resulting in hindering the interaction between MP and HY5 due to the Slym1 with a high expression level in ym mutant, lead to lots of the HY5 with unbound state accumulates in cells, that could accelerate the decomposition of chlorophyll. Therefore, the yellow leaf-color mutant ym could be used as an ideal material for further exploring the relationship between leaf color mutant and photosynthesis and the specific mechanism.

An Efficient Method for the Preparation of Sulfonamides from Sodium Sulfinates and Amines.

Sulfonamides have a special role on medicine due to their broad biological activities, as bacterial infections, diabetes mellitus, oedema, hypertension prevention and treatment. In addition, sulfonamides are also useful in herbicides and pesticides. Herein, we communicate an efficient strategy for the preparation of sulfonamides via NH4 I-mediated amination of sodium sulfinates. This new method provides a general and environmentally friendly access to sulfonamide compounds and tolerates a wide range of functional groups.

Identification of OSCA gene family in Solanum habrochaites and its function analysis under stress.

BACKGROUND: OSCA (hyperosmolality-gated calcium-permeable channel) is a calcium permeable cation channel protein that plays an important role in regulating plant signal transduction. It is involved in sensing changes in extracellular osmotic potential and an increase in Ca2+ concentration. S. habrochaites is a good genetic material for crop improvement against cold, late blight, planthopper and other diseases. Till date, there is no report on OSCA in S. habrochaites. Thus, in this study, we performed a genome-wide screen to identify OSCA genes in S. habrochaites and characterized their responses to biotic and abiotic stresses. RESULTS: A total of 11 ShOSCA genes distributed on 8 chromosomes were identified. Subcellular localization analysis showed that all members of ShOSCA localized on the plasma membrane and contained multiple stress-related cis acting elements. We observed that genome-wide duplication (WGD) occurred in the genetic evolution of ShOSCA5 (Solhab04g250600) and ShOSCA11 (Solhab12g051500). In addition, repeat events play an important role in the expansion of OSCA gene family. OSCA gene family of S. habrochaites used the time lines of expression studies by qRT-PCR, do indicate OSCAs responded to biotic stress (Botrytis cinerea) and abiotic stress (drought, low temperature and abscisic acid (ABA)). Among them, the expression of ShOSCAs changed significantly under four stresses. The resistance of silencing ShOSCA3 plants to the four stresses was reduced. CONCLUSION: This study identified the OSCA gene family of S. habrochaites for the first time and analyzed ShOSCA3 has stronger resistance to low temperature, ABA and Botrytis cinerea stress. This study provides a theoretical basis for clarifying the biological function of OSCA, and lays a foundation for tomato crop improvement.

Study on the Preparation and Effect of Tomato Seedling Disease Biocontrol Compound Seed-Coating Agent.

Tomato damping-off and root rot are the two most common diseases of tomatoes at the seedling stage. At present, biological compound seed-coating agents are gradually replacing chemical agents in preventing and controlling plant diseases and insect pests, regulating plant growth, and ensuring crop yields. In this study, five biocontrol bacteria (Bacillus amyloliquefaciens (Ba), Bacillus subtilis (Bs wy-1), Bacillus subtilis (WXCDD105), Pseudomonas fluorescens (WXCDD51), and Bacillus velezensis (WZ-37)), with broad antibacterial spectra were mixed with auxiliary factors (inactive components of seed-coating agent) after fermentation to compound a seed-coating agent. In this study, the formula for a compound seed-coating agent was selected through orthogonal experiment. Gaseous silica was used as a thickener, and gum arabic and sodium dodecylbenzene sulfonate were used as a film-forming agent and dispersant, respectively. The mass of fumed silica, gum arabic, sodium dodecylbenzene sulfonate, and pearlescent powder was 1.3 g, 1 g, 0.05 g, and 0.5 g, respectively. Adding gibberellin can improve the ability of seed-coating agents to promote seed germination and plant growth. This showed high efficiency in preventing and controlling seedling diseases and promoting seedling growth. After 6 days of inoculation with Pythium aphanidermatum, which caused tomato damping-off disease, the seedling mortality rate was 26.7% lower than that of the sterile water control, and 20% lower than that of carbendazim. After 21 days of inoculation with Fusarium sp., which caused tomato root rot disease, the seedling mortality rate was 44.31% lower than that of the control, and 22.36% lower than that of carbendazim. The plant height, stem diameter, root length, fresh weight, and dry weight of tomato seeds treated with biological compound seed-coating agent were significantly higher than that of the control. We tested the shelf life of the biological compound seed-coating agent, and found that the effect of seed germination and radicle growth did not decrease. This research provides information on the production technology and application of biological seed-coating agents in tomato production.

Low dose sacubitril/valsartan is effective and safe in hemodialysis patient with decompensated heart failure and hypotension: A case report.

RATIONALE: Severe heart failure in chronic hemodialysis (HD) patients is a great treatment challenge. Here we reported a chronic HD patient with the lowest ejection fraction reported so far and hypotension who well tolerated and benefited from angiotensin-receptor neprilysin inhibitor (ARNI) treatment. PATIENT CONCERNS: This case was a 67 year old lady with decompensated heart failure and hypotension who was on regular HD. Intensified hemofiltration failed to improve her heart failure symptoms and was also retarded by hypotension. DIAGNOSIS: Chronic HD with decompensated heart failure. INTERVENTIONS: In addition to regular HD, low does sacubitril/valsartan was initiated and titrated from 12/13 mg to 24/26 mg twice daily. OUTCOMES: Sacubitril/valsartan treatment was well tolerated and did not affect ultrafiltration during HD treatment. Transthoracic echocardiology at 3 months after initiation of ARNI treatment indicated significant improvement of both systolic and diastolic cardiac function. The patient has improved from New York Heart Association class 4 to class 2. LESSONS: Low does ARNI treatment could effectively improve cardiac function in HD patients with heart failure and hypotension. It was also safe and well tolerated.

Identification of CDPK Gene Family in Solanum habrochaites and Its Function Analysis under Stress.

Tomato is an important vegetable crop. In the process of tomato production, it will encounter abiotic stress, such as low temperature, drought, and high salt, and biotic stress, such as pathogen infection, which will seriously affect the yield of tomato. Calcium-dependent protein kinase (CDPK) is a class of major calcium signal receptor which has an important regulatory effect on the perception and decoding of calcium signals. CDPK plays a key role in many aspects of plant growth, such as the elongation of pollen tubes, plant growth, and response to biotic and abiotic stress. While some studies have concentrated on Arabidopsis and pepper, Solanum habrochaites is a wild species relative of cultivated tomato and there is no report on CDPK in Solanum habrochaites to date. Using tomato genomic data, this study identified 33 members of the CDPK gene family. Evolutionary analysis divides family members into four Asian groups, of which the CDPK family members have 11 gene replication pairs. Subcellular location analysis showed that most proteins were predicted to be located in the cytoplasm, and less protein existed on the cell membrane. Not all CDPK family members have a transmembrane domain. Cis regulatory elements relating to light, hormones, and drought stress are overrepresented in the promoter region of the CDPK genes in Solanum habrochaites. The expression levels of each gene under biotic stress and abiotic stress were quantified by qRT-PCR. The results showed that members of the CDPK family in Solanum habrochaites respond to different biotic and abiotic stresses. Among them, the expression of ShCDPK6 and ShCDPK26 genes change significantly. ShCDPK6 and ShCDPK26 genes were silenced using VIGS (virus-induced gene silencing), and the silenced plants illustrated reduced stress resistance to Botrytis cinerea, cold, and drought stress. The results of this study will provide a basis for the in-depth study of the CDPK gene family in Solanum habrochaites, laying the foundation for further analysis of the function of the gene family.
