Fluorescent chemosensors facilitate the visualization of plant health and their living environment in sustainable agriculture.

Globally, 91% of plant production encounters diverse environmental stresses that adversely affect their growth, leading to severe yield losses of 50-60%. In this case, monitoring the connection between the environment and plant health can balance population demands with environmental protection and resource distribution. Fluorescent chemosensors have shown great progress in monitoring the health and environment of plants due to their high sensitivity and biocompatibility. However, to date, no comprehensive analysis and systematic summary of fluorescent chemosensors used in monitoring the correlation between plant health and their environment have been reported. Thus, herein, we summarize the current fluorescent chemosensors ranging from their design strategies to applications in monitoring plant-environment interaction processes. First, we highlight the types of fluorescent chemosensors with design strategies to resolve the bottlenecks encountered in monitoring the health and living environment of plants. In addition, the applications of fluorescent small-molecule, nano and supramolecular chemosensors in the visualization of the health and living environment of plants are discussed. Finally, the major challenges and perspectives in this field are presented. This work will provide guidance for the design of efficient fluorescent chemosensors to monitor plant health, and then promote sustainable agricultural development.

Bioinspired PROTAC-induced macrophage fate determination alleviates atherosclerosis.

Atherosclerosis is a major cause of death and disability in cardiovascular disease. Atherosclerosis associated with lipid accumulation and chronic inflammation leads to plaques formation in arterial walls and luminal stenosis in carotid arteries. Current approaches such as surgery or treatment with statins encounter big challenges in curing atherosclerosis plaque. The infiltration of proinflammatory M1 macrophages plays an essential role in the occurrence and development of atherosclerosis plaque. A recent study shows that TRIM24, an E3 ubiquitin ligase of a Trim family protein, acts as a valve to inhibit the polarization of anti-inflammatory M2 macrophages, and elimination of TRIM24 opens an avenue to achieve the M2 polarization. Proteolysis-targeting chimera (PROTAC) technology has emerged as a novel tool for the selective degradation of targeting proteins. But the low bioavailability and cell specificity of PROTAC reagents hinder their applications in treating atherosclerosis plaque. In this study we constructed a type of bioinspired PROTAC by coating the PROTAC degrader (dTRIM24)-loaded PLGA nanoparticles with M2 macrophage membrane (MELT) for atherosclerosis treatment. MELT was characterized by morphology, size, and stability. MELT displayed enhanced specificity to M1 macrophages as well as acidic-responsive release of dTRIM24. After intravenous administration, MELT showed significantly improved accumulation in atherosclerotic plaque of high fat and high cholesterol diet-fed atherosclerotic (ApoE-/-) mice through binding to M1 macrophages and inducing effective and precise TRIM24 degradation, thus resulting in the polarization of M2 macrophages, which led to great reduction of plaque formation. These results suggest that MELT can be considered a potential therapeutic agent for targeting atherosclerotic plaque and alleviating atherosclerosis progression, providing an effective strategy for targeted atherosclerosis therapy.

Magnetic metal-organic framework MIL-100 (Fe)/polyethyleneimine composite as an adsorbent for the magnetic solid-phase extraction of fungicides and their determination using HPLC-UV.

Fe3O4@MIL-100 (Fe)/PEI are used for the first time as an adsorbent material for the extraction of pesticide residues (epoxiconazole, flusilazole, tebuconazole, and triadimefon) from food matrices. The adsorbent proposed (Fe3O4@MIL-100(Fe)/PEI) was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), thermogravimetric (TG) analysis, and vibrating sample magnetometer (VSM) techniques to evaluate the properties of the sorbent. Then, the Fe3O4@MIL-100 (Fe)/PEI was employed for the quantification of the four triazole fungicides in fruits and vegetables (apple, orange, tomato, cabbage, and cucumber) using HPLC-UV for separation and detection. During the extraction process, the main parameters such as amount of adsorbent, extraction time, pH value, ionic strength, eluting solvent, and eluting volume were optimized. Under the optimum conditions, good linearity of this method was observed for all analytes, with correlation coefficients (R2) ≥ 0.9908. The limits of detection (LODs) ranged from 0.021-3.04 µg kg-1. The extraction recoveries of the four triazole fungicides varied from 73.9 to 109.4% with relative standard deviations (RSD) in the range 0.5 to 6.2%. Compared with other MOFs, the modification of Fe3O4@MIL-100 (Fe) with PEI shows high efficient adsorption due to the combined benefits of MIL-100 (Fe) and PEI. The material is easily synthesized, has good stability, and is of low cost.  Graphical abstract.

Ultralow-Content Palladium Dispersed in Covalent Organic Framework for Highly Efficient and Selective Semihydrogenation of Alkynes.

Developing noble-metal-based catalysts with ultralow loading to achieve excellent performance for selective hydrogenation of alkynes under mild reaction conditions is highly desirable but still faces huge challenges. To this end, a SO3H-anchored covalent organic framework (COF-SO3H) as the support was deliberately designed, and then ultralow-content Pd (0.38 wt %) was loaded by a wet-chemistry immersion dispersion method. The resulting Pd0.38/COF-SO3H composite exhibits outstanding performance for the selective hydrogenation of phenylacetylene with 97.06% conversion and 93.15% selectivity to styrene under mild reaction conditions (1 bar of H2, 25 °C). Noticeably, the turnover frequency value reaches as high as 3888 h-1, which outperforms most of reported catalysts for such use. Moreover, such a catalyst also exhibits excellent activity for a series of other alkynes and high stability without obvious loss of catalytic performance after five consecutive cycles.

Diethylstilbestrol regulates mouse gubernaculum testis cell proliferation via PLC-Ca2+ -CREB pathway.

Recent evidence suggested a positive correlation between environmental estrogens (EEs) and high incidence of abnormalities in male urogenital system, but the mechanism remains unclear. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernaculum testis cells, but the underlying mechanism is unclear. In this study, mouse gubernaculum testis cells were pretreated with phospholipase C (PLC) inhibitor U-73122 and then treated with DES. The results demonstrated that U-73122 impaired DES-evoked intracellular Ca2+ mobilization in gubernaculum testis cells and inhibited DES-induced proliferation of gubernaculum testis cells. Mechanistically, we found that U-73122 inhibited DES-induced activation of cAMP-response element binding protein (CREB) in gubernaculum testis cells. In conclusion, these data suggest that the effects of DES on mouse gubernaculum testis cells are mediated by PLC-Ca2+ -CREB pathway. SIGNIFICANCE OF THE STUDY: Environmental estrogens remain a serious threat to male reproductive health, and it is important to understand the mechanism by which EEs affect the male productive system. Here we explore potential mechanisms how the proliferation and contractility of gubernaculum testis cells are regulated by diethylstilbestrol. Our findings provide the first evidence that PLC-Ca2+ -CREB signalling pathway mediates the nongenomic effects of diethylstilbestrol on gubernaculum testis cells. These findings provide new insight into the role of diethylstilbestrol in the aetiology of male reproductive dysfunction and will help develop better approaches for the prevention and therapy of male reproductive malformation.

The influence of microbial communities for triadimefon enantiomerization in soils with different pH values.

Enantiomers of chiral molecules can undergo interconversion leading to markedly different toxicities, which can introduce significant uncertainty when evaluating biological and environmental fates. However, enantiomerization (the reversible conversion of one enantiomer into the other) related to soil microorganism is rarely understood. For better understanding, S-triadimefon and R-triadimefon enantiopure were incubated in different soils with different pH value. Both high-performance liquid chromatography and high-throughput sequencing technology were used to explore target analytes quantitatively and microbial taxa related to the conversion process. Results revealed a significant enantiomerization among the soils. The alkaline soil from Beijing had a faster conversion than neutral soil from Changchun, while acidic soil from Wuhan had no conversion. At the same results, analysis of bacteria community showed higher abundance of Arthrobacter and Halomonas genus in alkaline soil than neutral soil after treatments, but the acidic soil was lower. Moreover, Arthrobacter and Halomonas were responsible for converting S-triadimefon to R-triadimefon and R-triadimefon to S-triadimefon in alkaline and neutral soil, respectively. Thus, these genera may be one of the reasons to explain the enantiomerization in different soils observed in this study. Thus, research at microbial level is necessary for efficient ecological risk assessment of chiral fungicide.

Characterization of a Putative S-layer Protein of a Colonial Microcystis Strain.

Cell surface structure plays a key role in Microcystis colony formation. The S-layer is a crystalline array of monomolecular proteins that constitute the outermost component of the cyanobacterial cell envelope. To date, no biochemical characterization of the S-layer protein in Microcystis has been reported. Here, we compared S-layer on the cell wall of the unicellular strain Microcystis aeruginosa PCC7806 with the colonial strain M. aeruginosa XW01. We observed crystalline S-layers in XW01 cell walls; however, similar structures were not observed in PCC7806. Sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis revealed a thick putative S-layer protein band with an apparent molecular weight of 70 kDa extracted from XW01 cells, as well as an S-layer peptide fragment with the sequence ETYPLLAAPGAATDATR, similar to the translated product from PCC7806 unknown gene CAO89090.1. The amino acid composition of the translated CAO89090.1 product shared biochemical characteristics with those of bacterial S-layer proteins. Furthermore, a 1002-bp DNA fragment amplified from XW01 displayed 95% similarity with the CAO89090.1 gene, while the S-layer gene expression in XW01 was 36-fold higher than that observed in PCC7806. These data suggested that the S-layer protein plays a key role in Microcystis colony formation due to its significant contribution to cell surface hydrophobicity.

Prediction of 10-year Atherosclerotic Cardiovascular Disease Risk among Adults Aged 40-79 Years in China: a Nationally Representative Survey.

OBJECTIVE: To establish the distribution of 10-year atherosclerotic cardiovascular disease (ASCVD) risk among Chinese adults. METHODS: We estimated the 10-year ASCVD risk by applying the 2013 American College of Cardiology/ American Heart Association pooled cohort equations (PCEs) to the data obtained from the 2010 China Chronic Disease and Risk Factor Surveillance that involved 61,541 participants (representing 520,158,652 Chinese adults) aged 40-79 years. We also compared the ASCVD risk with the 10-year ischemic cardiovascular disease (ICVD) risk, which was calculated using the simplified scoring tables recommended by the Chinese Guidelines for Prevention of Cardiovascular Diseases (Chinese model). RESULTS: Based on the PCEs, the average 10-year ASCVD risk among adults without self-reported stroke or myocardial infraction was 12.5%. Approximately 247 million (47.4%) and 107 million (20.6%) adults had ⋝ 7.5% and > 20% 10-year ASCVD risks, respectively. The 10-year ASCVD risk > 20% was higher among men, less educated individuals, smokers, drinkers, and physically inactive individuals than among their counterparts. Overall, 29.0% of adults categorized using the Chinese model were overclassified with the PCEs. CONCLUSION: Our results define the distribution of 10-year ASCVD risk among Chinese adults. The 10-year ASCVD risk predicted by the PCEs was higher than the ICVD risk predicted by the Chinese model.

Gender-specific Association of Sleep Duration with Body Mass Index, Waist Circumference, and Body Fat in Chinese Adults.

OBJECTIVE: To examine the association between habitual sleep duration and obesity among Chinese adults. METHODS: The association of sleep duration and obesity was investigated among 7,094 community-dwelling Chinese adults. Sleep duration was self-reported. In this study, obesity was defined as follows: body mass index (BMI) ⋝ 28 kg/m2, waist circumference (WC) ⋝ 85 cm in men and ⋝ 80 cm in women, and percent body fat (%BF) ⋝ 25 in men and ⋝ 35 in women. Logistic and quantile regressions were employed to examine relationships of interest. RESULTS: Overall, 6.42% of the participants reported short sleep durations (< 6 h/d) while 14.71% reported long (⋝ 9 h/d) sleep durations. Long sleepers (⋝ 9 h/d) represented a greater frequency of women with obesity [odds ratio (OR): 1.30; 95% confidence interval (CI), 1.02-1.67] and high body fat (1.43, 1.04-1.96) than those who slept 7-8 h/d. An association between long sleep times and higher BMI estimations was found across the 10th-75th percentile of the BMI distribution. Among men, long sleepers (⋝ 9 h/d) presented lower risks of developing abdominal obesity compared with individuals who slept 7-8 h/d (OR = 0.79, 95% CI: 0.44-0.99). CONCLUSION: Our study suggests that long sleep durations are associated with general obesity in Chinese women but reduced waist circumferences in men. Confirmatory studies are needed to determine the heterogeneous association of sleep time and obesity by gender.

[Impacts of DES on the expressions of related genes in the gubernaculums testis of newborn mice].

OBJECTIVE: To investigate the influence of diethylstilbestrol (DES) on the mRNA expressions of the androgen receptor (AR), estrogen receptor α (ERα), proliferating cell nuclear antigen (PCNA), and actin alpha 1 (ACTα1) in the gubernaculums testis of newborn mice and explore their action mechanisms. METHODS: A total of 140 male Kunming mice were randomly divided into a blank control, a dimethyl sulfoxide (DMSO) control, and 5 experimental groups to be treated subcutaneously with normal saline, DMSO, and DES at 0.02, 0.1, 0.5, 10 and 50 µg per kg of the body weight per day, respectively, at gestation days 9－17. On the first day after birth, the animals were sacrificed and the gubernaculums testis collected for detection of the mRNA expressions of AR, ERα, PCNA and ACTα1 by RT-PCR. RESULTS: Compared with the DMSO control, the experimental groups, particularly the DES 10 and 50 µg groups, showed significant increases in the mRNA expression of ERα (RE2 = 0.825, P <0.05), but remarkable decreases in those of AR, PCNA and ACTα1 (RA2 = 0.713, RP2 = 0.946, RT2 = 0.960, P <0.01), all in a dose-dependent manner. CONCLUSIONS: The AR, ERα, PCNA, and ACTα1 mRNA are expressed in the gubernaculum testis of normal newborn mice, and their expression levels may be influenced by intervention with different concentrations of DES during the gestation. Exogenous estrogens may affect the proliferation and contraction of gubernaculum testis cells and consequently the normal development of the testis or even the whole male reproductive system by influencing the metabolism of ER and/or AR.

Growth and antioxidant production of Spirulina in different NaCl concentrations.

OBJECTIVE: To evaluate the quantity of Spirulina cultured in seawater, salt-tolerant strains were screened out and their growth and antioxidant accumulation were studied in different salt concentrations RESULTS: Salt tolerance of five Spirulina strains were investigated with modified Zarrouk medium (with 200-800 mM NaCl). All strains grew well with 400 mM NaCl; their growth rates were almost same as in the control medium. Spirulina strains FACHB-843 (SP843) and FACHB-972 (SP972) had the highest salt tolerance their growth rates in 600 mM NaCl were nearly same as the control. Both strains produced more carotene, phycocyanin, polysaccharides, proline and betaine in 400-600 mM NaCl than the control. Salt stress also induced them to produce higher activities of superoxide dismutase and peroxidase. Total antioxidant capacities of SP843 and SP972 peaked at 600 and 400 mM NaCl, respectively. CONCLUSION: Spirulina strains cultured with seawater accumulate more bioactive substances and will have a higher nutritive value.

Prevalence of Major Cardiovascular Risk Factors and Cardiovascular Disease in Women in China: Surveillance Efforts.

In this study, we aimed to assess the relationship of socioeconomic status and acculturation with cardiovascular disease (CVD) risk profiles and CVD and examine the CVD risk factors associated with CVD. We used data from the 2010 China Chronic Disease and Risk Factor Surveillance surveys, which consisted of a nationally representative sample of women. The following prevalence was found: myocardial infarction (MI): 0.4%; stroke: 0.5%; abnormal cholesterolemia: 44.9%; overweight or obesity: 32.2%; hypertension: 31.7%; diabetes: 9.0%; and smoking: 2.5%. In total, 30.9% of Chinese women had no risk factors, but 13.3% had ⋝3 associated risk factors. In multivariate-adjusted models, hypertension, diabetes, overweight or obese, and smoking were all directly associated with MI; For stroke, associations were positive with hypertension, abnormal cholesterolemia, diabetes, and overweight or obesity. Therefore, it can be concluded that CVD risk factors are common among Chinese women aged ⋝18 years.

Antitumor activity of photodynamic therapy with a chlorin derivative in vitro and in vivo.

Chlorin derivatives are promising photosensitive agents for photodynamic therapy (PDT) of tumors. The aim of the current study is to investigate the PDT therapeutic effects of a novel chlorin-based photosensitizer, meso-tetra[3-(N,N-diethyl)aminomethyl-4-methoxy]phenyl chlorin (TMPC) for gliomas in vitro and in vivo. Physicochemical characteristics of TMPC were recorded by ultraviolet visible spectrophotometer and fluorescence spectrometer. The rate of singlet oxygen generation of TMPC upon photo-excitation was detected by using 1,3-diphenylisobenzofuran (DPBF). The accumulation of TMPC in gliomas U87 MG cells was measured by fluorescence spectrometer. The efficiency of TMPC-PDT in vitro was analyzed by MTT assay and clonogenic assay. The biodistribution and clearance of TMPC were determined by fluorescence measuring. Human gliomas U87 MG tumor-bearing mice model was used to evaluate the antitumor effects of TMPC-PDT. TMPC shows a singlet oxygen generation rate of 0.05 and displays a characteristic long wavelength absorption peak at 653 nm (ε = 15,400). The accumulation of TMPC increased with the increase of incubation time. In vitro, PDT using TMPC and laser showed laser dose- and concentration-dependent cytotoxicity to U87 MG cells. In U87 MG tumor-bearing mice, TMPC-PDT significantly reduced the growth of the tumors. Both in vitro and in vivo, TMPC showed little dark toxicity. In vitro and in vivo studies, it found that TMPC has excellent antitumor activities. It suggests that TMPC is a potential photosensitizer of photodynamic therapy for cancer.

Negative Association of Domestic Activity and Active Commuting with Metabolic Syndrome in a Chinese Population Aged 35-64 Years.

OBJECTIVE: To understand the associations of physical activity domains with metabolic syndrome among a middle-aged Chinese population. METHODS: In all, 3326 professional adults aged 35-64 years from Beijing and Zhejiang province were recruited with a cluster random sampling method. The Global Physical Activity Questionnaire was modified, and the recommended Asia-Pacific cut-offs of waist circumstance were introduced into the criteria for metabolic syndrome from the Adult Treatment Panel III. A binary logistic regression model was applied to examine the association of all physical activity domains with the risk of the syndrome. RESULTS: Participants who engaged in domestic activity for ⋜1176 MET-min/week had a 41.6% less chance of having metabolic syndrome [odds ratio (OR), 0.584; 95% confidence interval (CI), 0.480-0.710] than those without this activity. In adjusted models, adults who actively commuted for ⋜33 MET-min/week but <528 MET-min/week had a 25% less chance of having the syndrome (OR, 0.750; 95% CI, 0.582-0.966) than those who did not. No interaction was detected between the two domains of activity and the syndrome. CONCLUSION: This study highlighted the independently negative association of traffic and house activity with the prevalence of the syndrome in this sample with a generally low level of moderate activity.

Synthesis and Herbicidal Activity of 5-Heterocycloxy-3-methyl-1-substituted-1H-pyrazoles.

With the objective of finding valuable herbicidal candidates, a series of new 5-heterocycloxy-3-methyl-1-substituted-1H-pyrazoles were synthesized and their herbicidal activities were evaluated. The bioassay results showed that some compounds exhibited excellent herbicidal activities at the concentration of 100 mg/L, and compound 5-chloro-2-((3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazol-5-yl)oxy)pyrimidine showed bleaching activity to green weeds. In greenhouse conditions, this compound also showed excellent post-emergence herbicidal effect against Digitaria sanguinalis L. at the dosage of 750 g a. i. ha(-1).

[CCL19/IL-1beta positive feedback loop involved in the progress of inflammation in rheumatoid arthritis].

OBJECTIVE: To explore the function and mechanism of CCL19 in the pathogenesis of rheumatoid arthritis. METHODS: Synovial fibroblasts were collected from 5 cases of rheumatoid arthritis. Peripheral blood mononuclear cells (PBMCs) were obtained from 5 healthy people by Ficoll-Hypaque density gradien centrifugation. The cells were stimulated with IL-1beta, TNF-alpha, IL-17 and other cytokines, and then the expression of CCL19 was detected by RT-PCR. The cells also were treated with different concentration of CCL19, then the expressions of IL-1beta, TNF-alpha were detected by RT-PCR, the expressions of p-ERK, p-p38 were detected by western blot. RESULTS: IL-1beta promoted the CCL19/CCR7 expression in both synovial fibroblasts and PBMCs. CCL19 upregulated the expression of IL-10 in both synovial fibroblasts and PBMCs. The stimulation of CCL19 also increased its receptor CCR7 expression. CCL19 activated p-ERK and p-p38 in PBMCs. CONCLUSION: The positive feedback loop between CCL19 and IL-1 participate in the development of rheumatoid arthritis.

Dietary sodium intake and its impact factors in adults of Shandong province.

Dietary sodium intake and its impact factors in 2 140 adults aged 18-69 years were analyzed. The mean daily sodium intake was 5745.0 (5427.6-6062.5) mg per day, which was higher in males than in females (P<0.01). After having been adjusted for gender, age and urban/city areas, the mean daily sodium intake was significantly higher in participants with a lower education level, drinkers and smokers than in those with a higher education level, nondrinkers and nonsmokers (P<0.01). The dietary sodium intake in adults of Shandong Province is higher than the recommended standards.

G protein-coupled estrogen receptor-protein kinase A-ERK-CREB signaling pathway is involved in the regulation of mouse gubernaculum testis cells by diethylstilbestrol.

The etiology of testicular dysgenesis syndrome is multifactorial and involves environmental factors, such as environmental estrogens. Several studies have shown that hormonal effects on the gubernaculum may affect testicular descent. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernacular cells, but the underlying mechanisms remain elusive. In this study, we aimed to determine whether DES may regulate the function of gubernaculum testis cells by way of nongenomic effects mediated by G protein-coupled estrogen receptor (GPER). We used cultured mouse gubernacular testis cells to demonstrate that GPER is expressed in gubernaculum testis cells. Erk1/2 inhibitor PD98059, PKA inhibitor H89, and Src inhibitor PP2 relieved DES-induced inhibition of gubernaculum testis cell proliferation, but ER inhibitor ICI 182780 had no effects on DES-induced inhibition of gubernaculum testis cell proliferation. In addition, we found that DES induced the activation of CREB downstream of PKA, Src, and ERK1/2 in these cells. These data suggest that the effects of DES on mouse gubernaculum testis cells are mediated at least partially by GPER-protein kinase A-ERK-CREB signaling pathway.

Effects of Housing Systems on Behaviour, Performance and Welfare of Fast-growing Broilers.

This experiment aimed to evaluate the effects of different housing systems on behavioral activities, welfare and meat quality of fast-growing broilers. Two hundred broilers were allocated into two housing systems: indoor housing vs indoor with outdoor access. Their general behavior (feeding, drinking, fighting, standing, lying, walking, investigating, dust-bathing and preening) was observed, and tonic immobility, fluctuating asymmetry of legs and wings were measured, and meat quality was analyzed. The results showed that the indoor-housed broilers with outdoor access had significant higher standing, walking, investigating, dust-bathing and preening than those indoor only. However, farming system was not found to significantly affect their feeding, drinking and fighting activities (p>0.05). The value of FA of tibia length of the broilers with outdoor access was significantly lower than that of the indoor-housed birds (1.57±1.30 vs 2.76±1.40, p<0.05), while no difference was found for the value of FA in tibia diameter and wing length (p>0.05). TI of the broilers with outdoor access was 165.5 that was significantly higher than that (147.2) of the indoor birds (p<0.05). However, death rate in the outdoor run groups was significantly higher than that of the indoor ones (2.0±0.81 vs 4.0±0.82, p<0.05). Meat quality was not affected by the two farming systems. It can be concluded that the results of this study may suggest that the indoor housing with outdoor access provides enriched environment for broilers and facilitates the expression of natural behaviors of the broilers but resulted in poorer performance and higher death rate.
