Inflammatory bowel disease (IBD) is a chronic and relapsing immune‐mediated disease of the gastrointestinal tract with a gradually increasing global incidence and prevalence. A prolonged course of IBD leads to a decline in patient quality of life and the creation of a substantial economic burden on society. Owing to the lack of specific diagnostic markers, the diagnosis of IBD still needs a gold standard based on a combination of clinical manifestations, imaging, laboratory, and endoscopic results. Accordingly, the current goals of IBD treatment are to alleviate clinical symptoms and reduce recurrence rates. Therefore, it is imperative to develop a standard set of procedures to diagnose and treat IBD. In this review, we summarize prominent and emerging studies, outline classical and contemporary approaches to diagnosing and managing IBD, and integrate multiple guidelines. Furthermore, we propose the possibility of establishing an early and comprehensive diagnostic workflow and personalized management strategy in the future. We aim to enhance the quality and standardization of diagnostic and treatment procedures for IBD. [ABSTRACT FROM AUTHOR]

Introduction: The incidence of metabolic syndrome (MetS) in people living with HIV is significantly higher than in people without HIV. MetS is not only a major driver of cardiovascular disease (CVD) but is also closely related to the development of chronic kidney disease (CKD). The aim of this study was to investigate the prevalence of and risk factors for MetS and to further understand the degree of damage to target organs. Methods: This was a cross‐sectional descriptive study conducted at Chongqing Public Health Medical Center, China. Information was collected via questionnaire survey, physical examination, and laboratory tests. We used the China Diabetes Society guidelines to define MetS. Pooled cohort equations were calculated to compare CVD risk in the next 10 years in people living with HIV aged ≥40 years with or without MetS. We used Student's t‐test, the chi‐squared test, Fisher's exact test, binary logistic regression, and multiple linear regression in the statistical analysis. Results: The study included 979 people living with HIV, including 13 who have experienced CVD, receiving antiretroviral therapy (ART). The median age was 43.0 years, 20.9% were female, and the median ART time was 45.0 months. The prevalence of MetS was 33.9%. The components of MetS criteria were hyperglycaemia (50.4%), hypertriglyceridaemia (48.4%), hypertension (46.8%), low concentrations of high‐density lipoprotein cholesterol (28.2%), and abdominal obesity (25.0%). Higher body mass index (odds ratio [OR] 1.266; 95% confidence interval [CI] 1.203–1.333), higher total cholesterol (OR 1.267; 95% CI 1.011–1.588), high alcohol consumption (OR 1.973; 95% CI 1.009–3.859), and family history of diabetes (OR 1.726; 95% CI 1.075–2.770) were independent risk factors for MetS. Compared with the non‐MetS group, the MetS group had a higher rate of urine albumin (23.8% vs 14.8%, p = 0.001), and the estimated glomerular filtration rate <90 mL/min/1.73 m2 (18.37% vs. 12.8%, p = 0.020) and β2‐microglobin (p = 0.004) increased more markedly in the MetS group. Regarding the risk of developing CVD events in the next 10 years, 38.5% of those in the MetS group were at high or very high risk, which was significantly higher than in the non‐MetS group (p < 0.001). In addition, age (p < 0.001) and sex (p = 0.002) are independent risk factors for developing CVD events in the next 10 years. Conclusions: The prevalence of MetS in people living with HIV on ART is high in Chongqing, China. Risk factors for the development of MetS are high alcohol consumption, family history of diabetes, higher body mass index, and higher total cholesterol levels. In addition, MetS is associated with a risk of CKD and the incidence of 10‐year CVD. [ABSTRACT FROM AUTHOR]

Recovery growth is common in relay intercropping systems and is a useful practice to increase total productivity of these systems. A field experiment was conducted during 2014–2016 to investigate the phenotypic and physiological traits related to light interception and utilization changes and cultivars difference of soybean during the recovery growth period. Two cropping patterns (maize–soybean relay strip intercropping (RSI), analogous soybean monoculture (CK)) and two soybean cultivars (shade‐tolerant Nandou12 and shade non‐tolerant Jiuyuehuang) were evaluated. During the co‐growth period, the growth of both two soybean cultivars was suppressed and showed a series of shade avoidance traits. After maize harvest, the LAI and leaflet number of intercropped soybean exhibited rapid growth, the LAI of Nandou12 (3.09) and Jiuyuehuang (1.32) recovered to 79% and 43% of corresponding CK level, respectively. Subsequently, final biomass of Nandou12 (3972.7 kg ha−1) and Jiuyuehuang (2263.3 kg ha−1) recovered 85.7% and 52% of corresponding CK level, respectively. Leaf blade thickness of Nandou12 recovered to the corresponding CK level, while Jiuyuehuang was not. Pn recovered to 84.5% and 82.8% of sole Pn at 80 days after soybean sowing in 2015 and to 72% and 91.2% at 66 days after soybean sowing in 2016 for Nandou12 and Jiuyuehuang, respectively. The above recovery process promoted the recovery of pod formation and grain yield. The yield of Nandou12 (1159.5 kg ha−1) has no significant difference between the CK level (1325.5 kg ha−1) but significantly higher than that of Jiuyuehuang (566.8 kg ha−1). Taken together, some recovery growth did occur in Jiuyuehuang, but it did not completely compensate for the growth reduction that occurred during the co‐growth period. Shade‐tolerant soybean cultivar has more stronger recovery growth ability in LAI, leaflet number, leaf thickness, and photosynthesis after maize harvest, which promoted the recovery growth of aboveground biomass and grain yield.

Mildew severely reduces soybean yield and quality, and pods are the first line of defence against pathogens. Maize‐soybean intercropping (MSI) reduces mildew incidence on soybean pods; however, the mechanism remains unclear. Changing light (CL) from maize shading is the most important environmental feature in MSI. We hypothesized that CL affects isoflavone accumulation in soybean pods, affecting their disease resistance. In the present study, shading treatments were applied to soybean plants during different developmental stages according to various CL environments under MSI. Chlorophyll fluorescence imaging (CFI) and classical evaluation methods confirmed that CL, especially vegetative stage shading (VS), enhanced pod resistance to mildew. Further metabolomic analyses and exogenous jasmonic acid (JA) and biosynthesis inhibitor experiments revealed the important relationship between JA and isoflavone biosynthesis, which had a synergistic effect on the enhanced resistance of CL‐treated pods to mildew. VS promoted the biosynthesis and accumulation of constitutive isoflavones upstream of the isoflavone pathway, such as aglycones and glycosides, in soybean pods. When mildew infects pods, endogenous JA signalling stimulated the biosynthesis of downstream inducible malonyl isoflavone (MIF) and glyceollin to improve pod resistance. Changing light from maize shading is the most important environmental feature in maize‐soybean intercropping, which reduces mildew incidence on soybean (Glycine max L. Merr.) pods.Weak to bright light conditions promotes constitutive isoflavone biosynthesis in soybean pods, and provides sufficient precursors for downstream inducible malonylated isoflavones and glyceolin to improve pod resistance.JA signalling and isoflavone have a synergistic effect on the enhanced resistance of changing light treated pods to mildew.

Although considerable efforts have been made in transforming carbon dioxide into high value‐added products, it still remains a big challenge to convert CO2 to CH4 directly at low temperature. Here, we report transition metals (including Fe, Co, Cr and Mn) modified Ni catalysts supported on Al2O3−ZrO2 via a single‐step sol‐gel method for low temperature CO2 methanation. Specially, incorporation of Mn metal into the Ni/Al2O3−ZrO2 catalyst was the most beneficial to the reduction and dispersion of NiO particles on the surface of Al2O3−ZrO2 composite support in comparison to other transition metals such as Fe, Co and Cr, which promoted the formation of active metallic Ni sites. Furthermore, the addition of Mn promoter facilitated the formation of surface oxygen vacancies, which combined with more metallic Ni active sites, thus improving the low‐temperature CO2 methanation performance significantly. An optimized Ni−Mn/Al2O3−ZrO2‐1 catalyst exhibited a superior CO2 conversion of 78 % with CH4 selectivity almost 100 % at a lower temperature of 300 °C without any deactivation in the long term 100 h reaction, which presented a potential industrial application for CO2 methanation.

Influences of planting density and nitrogen rate have been investigated frequently in targeted wheat (Triticum aestivum L.) research. Few studies have investigated interactions between these inputs. The objective was to determine the combine effect of N and seeding rates on culm morph‐physiological traits for lodging tolerance and grain yield. The experiment used a split‐split randomized block design using two wheat varieties 'AnNong0711' and 'YanNong19', split by four seeding (180, 240, 300, and 375 × 104 ha−1) and four N rates (0, 180, 240, and 300 kg ha−1). Lodging traits of plant height, culm height center of gravity, and internode length, increased (p <.05) however, stem diameter, wall thickness, and stem breaking strength decreased with increasing N and seeding rate. Stem breaking strength was negatively correlated with culm height center of gravity (r = −.869, p =.01), internode length (r = −.872, p <.01), and lignin (r = −.746, p <.01) but positively correlated with internode diameter (r =.715, p <.05) and wall thickness (r =.696, p <.05). Culm lodging index and cellulose showed positive correlation (r =.807 and.913 respectively) with lignin. Compared to YanNong19, AnNong0711 showed higher grain yield and culm lodging index of 9 and 20.49%, respectively. For improved grain yield, 180 plants m−2 was optimal in surface combinations with 210 kg N ha−1 for AnNong0711 and 200 kg N ha−1 for YanNong19. These combinations of seeding and N rates could successfully mitigate lodging and improve grain yield. [ABSTRACT FROM AUTHOR]

A three‐dimensional (3D) hierarchical MOF‐on‐reduced graphene oxide (MOF‐on‐rGO) compartment was successfully synthesized through an in situ reduced and combined process. The unique properties of the MOF‐on‐rGO compartment combining the polarity and porous features of MOFs with the high conductivity of rGO make it an ideal candidate as a sulfur host in lithium–sulfur (Li‐S) batteries. A high initial discharge capacity of 1250 mAh g−1 at a current density of 0.1 C (1.0 C=1675 mAh g−1) was reached using the MOF‐on‐rGO based electrode. At the rate of 1.0 C, a high specific capacity of 601 mAh g−1 was still maintained after 400 discharge–charge cycles, which could be ascribed to the synergistic effect between MOFs and rGO. Both the hierarchical structures of rGO and the polar pore environment of MOF retard the diffusion and migration of soluble polysulfide, contributing to a stable cycling performance. Moreover, the spongy‐layered rGO can buffer the volume expansion and contraction changes, thus supplying stable structures for Li‐S batteries. [ABSTRACT FROM AUTHOR]

Abstract: We report a new method to promote the conductivities of metal–organic frameworks (MOFs) by 5 to 7 magnitudes, thus their potential in electrochemical applications can be fully revealed. This method combines the polarity and porosity advantages of MOFs with the conductive feature of conductive polymers, in this case, polypyrrole (ppy), to construct ppy‐MOF compartments for the confinement of sulfur in Li–S batteries. The performances of these ppy‐S‐in‐MOF electrodes exceed those of their MOF and ppy counterparts, especially at high charge–discharge rates. For the first time, the critical role of ion diffusion to the high rate performance was elucidated by comparing ppy‐MOF compartments with different pore geometries. The ppy‐S‐in‐PCN‐224 electrode with cross‐linked pores and tunnels stood out, with a high capacity of 670 and 440 mAh g−1 at 10.0 C after 200 and 1000 cycles, respectively, representing a new benchmark for long‐cycle performance at high rate in Li–S batteries.

BACKGROUND RESULTS CONCLUSION Relay intercropping of maize and soybean can improve land productivity. However, the mechanism behind N2O emissions in this practice remains unclear. A two‐factor randomized block field trial was conducted to reveal the mechanism of N2O emissions in a full additive maize–soybean relay intercropping. Factor A was three cropping systems – that is, monoculture maize (Zea mays L.), monoculture soybean (Glycine max L. Merr.) and maize–soybean relay intercropping. Factor B was different N supply, containing no N, reduced N and conventional N. Differences in N2O emissions, soil properties, rhizosphere bacterial communities and yield advantage were evaluated.The land equivalent ratio was 1.55–2.44, and the cumulative N2O emission (CEN2O$$ \mathrm{C}{\mathrm{E}}_{{\mathrm{N}}_2\mathrm{O}} $$) was notably lower by 60.2% in intercropping than in monoculture, respectively. Reduced N declined CEN2O$$ \mathrm{C}{\mathrm{E}}_{{\mathrm{N}}_2\mathrm{O}} $$ without penalty on the yield advantages. The relay intercropping shifted soil properties – for example, soil organic matter, total N, NH4+$$ {\mathrm{NH}}_4^{+} $$ and protease activity – and improved the soil microorganism community – for example, Proteobacteria and Acidobacteria. Intercropping reduced CEN2O$$ \mathrm{C}{\mathrm{E}}_{{\mathrm{N}}_2\mathrm{O}} $$ by directly suppressing nirS‐ and amoA‐regulated N2O generation during soil N cycling, or nirS‐ and amoA‐mediated soil properties shifted to reduce CEN2O$$ \mathrm{C}{\mathrm{E}}_{{\mathrm{N}}_2\mathrm{O}} $$ indirectly. Reduced N directly reduced CEN2O$$ \mathrm{C}{\mathrm{E}}_{{\mathrm{N}}_2\mathrm{O}} $$ by decreasing soil N content and reducing soil microorganism activities to alleviate N2O produced in soil N cycling.Conducting a full additive maize–soybean relay intercropping with reduced nitrogen supply provides a way to alleviate N2O emissions without the penalty on the yield advantage by changing rhizosphere bacterial communities and soil N cycling. © 2024 Society of Chemical Industry.
