The mango bacterial black spot altered the endophyte community structure and diversity.

Mango bacterial black spot is a major disease limiting mango production, which is now causing increasingly severe economic losses. In this study, we analyzed the differences in the composition and structure of bacterial and fungal communities in the pulp and leaves between the healthy mangoes of variety Kate and those affected by bacterial black spot, and attempted to explore potential biocontrol microorganisms for mangoes. The results showed there existed significant differences in microbial communities, the bacterial Stenotrophomonas, Curtobacterium, Massilia and fungous Penicillium, Alternaria, Aureobasidiu showed great abundance both in pulps and leaves.

The biological function of m6A methyltransferase KIAA1429 and its role in human disease.

KIAA1429 is a major m6A methyltransferase, which plays important biological and pharmacological roles in both human cancer or non-cancer diseases. KIAA1429 produce a tumorigenic role in various cancers through regulating DAPK3, ID2, GATA3, SMC1A, CDK1, SIRT1 and other targets, promoting cell proliferation, migration, invasion, metastasis and tumor growth . At the same time, KIAA1429 is also effective in non-tumor diseases, such as reproductive system and cardiovascular system diseases.

[Effects of addition of organic carbon with different chemical structure on the fate and accumulation of exogenous carbon in red and sandy soils].

Plant litter input has important influences on soil CO emission and soil organic carbon (SOC) formation in terrestrial ecosystem. However, it is not well known for the fate of carbon when exogenous organic matters with different chemical structures are added to soil with different textures. In this study, we added the uniformly C-labelled substrates of glucose, starch, and cellulose to red soil and sandy soil, and compared the net C accumulation and recovery and its proportions in soil releasing CO, SOC, dissolved organic carbon (DOC) and microbial biomass carbon (MBC) pools.

Unexpected Cascade Dehydrogenation Triggered by Pd/Cu-Catalyzed C(sp)-H Arylation/Intramolecular C-N Coupling of Amides: Facile Access to 1,2-Dihydroquinolines.

In this work, we successfully explored an unexpected dehydrogenation triggered by Pd/Cu-catalyzed C(sp)-H arylation and intramolecular C-N coupling of amides to synthesize the bioactive 1,2-dihydroquinoline scaffold with good regioselectivity and good compatibility of functional groups. This strategy provides an alternative route to realize molecular complexity and diversity from simple and readily available molecules via multiple C-H bond activation. Preliminary mechanistic studies demonstrated that β,γ-dehydrogenation is triggered by the arylation of the C(sp)-H bond and the intramolecular C-N coupling.

Breviscapine remodels myocardial glucose and lipid metabolism by regulating serotonin to alleviate doxorubicin-induced cardiotoxicity.

The broad-spectrum anticancer drug doxorubicin (Dox) is associated with a high incidence of cardiotoxicity, which severely affects the clinical application of the drug and patients' quality of life. Here, we assess how Dox modulates myocardial energy and contractile function and this could aid the development of relevant protective drugs. Mice were subjected to doxorubicin and breviscapine treatment.

Targeting NAD+: is it a common strategy to delay heart aging?

Heart aging is the main susceptible factor to coronary heart disease and significantly increases the risk of heart failure, especially when the aging heart is suffering from ischemia-reperfusion injury. Numerous studies with NAD+ supplementations have suggested its use in anti-aging treatment. However, systematic reviews regarding the overall role of NAD+ in cardiac aging are scarce.

Nicotinic Acid Riboside Regulates Nrf-2/P62-Related Oxidative Stress and Autophagy to Attenuate Doxorubicin-Induced Cardiomyocyte Injury.

Doxorubicin (Dox) is an effective chemotherapeutic drug for the treatment of various cancers. Due to its potential fatal cardiotoxic side effects, the clinical application is often limited. Dexrazoxane (Dex) is the only drug approved by the Food and Drug Administration (FDA) for the prevention of Dox-induced cardiotoxicity but has side effects.

Effects of aboveground and belowground litter inputs on the balance of soil new and old organic carbon under the typical forests in subtropical region.

Litter is one of the most important factors controlling the accumulation, stabilization, and turnover of soil organic carbon (SOC) in forests. There is a knowledge gap of the impacts of aboveground and belowground litter inputs on the balance of new and old SOC under different forests in subtropical region. We examined the effects of aboveground and belowground litter inputs on SOC turnover using isotopic tracing technique, based on a 3-year C3 plants/C4 soil replacement experiment in natural forest (NF), Masson pine () plantation (PM) and Chinese fir () plantation (CL).

Diffuse large B-cell lymphoma with low F-fluorodeoxyglucose avidity features silent B-cell receptor signaling.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of aggressive lymphomas exhibiting increased glucose uptake. However, some DLBCLs featuring relatively low F-fluorodeoxyglucose (F-FDG) uptake denoted by the maximum standardized uptake value (SUV) on PET/CT have been identified. The biologic correlates of such a heterogeneity have remained largely unknown.

[Relationship Between the VNTR Loci Polymorphism and MALDI-TOF MS Protein Profile Diversity in Complex].

Objective: To study the relationship between the copy numbers of repetitive units at variable number tandem repeat (VNTR) loci of complex (MTBC) with its diversity of protein profiles.

Methods: The MTBC strains were subjected to genotyping using multiple locus variable number tandem repeat analysis (MLVA). Also, the principal component analysis (PCA) was performed for bacterial protein profiles of MTBC using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).

Heat Stress Modulates Mycelium Growth, Heat Shock Protein Expression, Ganoderic Acid Biosynthesis, and Hyphal Branching of Ganoderma lucidum via Cytosolic Ca2.

Unlabelled: Heat stress (HS) influences the growth and development of organisms. Thus, a comprehensive understanding of how organisms sense HS and respond to it is required. Ganoderma lucidum, a higher basidiomycete with bioactive secondary metabolites, has become a potential model system due to the complete sequencing of its genome, transgenic systems, and reliable reverse genetic tools.

Role of gefitinib in the targeted treatment of non-small-cell lung cancer in Chinese patients.

Non-small-cell lung cancer (NSCLC) is the most common type of lung cancer. Conventional treatment options have limited efficacy because most cases are in the advanced stage at the time of diagnosis. In recent years, gefitinib, an epidermal growth factor receptor tyrosine kinase inhibitor, has shown its good antitumor activities in treating NSCLC in a number of studies.

Profiling and quantifying differential gene transcription provide insights into ganoderic acid biosynthesis in Ganoderma lucidum in response to methyl jasmonate.

Ganoderma lucidum is a mushroom with traditional medicinal properties that has been widely used in China and other countries in Eastern Asia. Ganoderic acids (GA) produced by G. lucidum exhibit important pharmacological activities.

Crystal structures and phase-transition dynamics of cobaltocenium salts with bis(perfluoroalkylsulfonyl)amide anions: remarkable odd-even effect of the fluorocarbon chains in the anion.

Crystal structures and thermal properties of cobaltocenium salts with bis(perfluoroalkylsulfonyl)amide (C(n)F2(n+1)SO2)2N anions [n = 0 (1), 1 (1 a), 2 (1 b), 3 (1 c), and 4 (1 d)] and the 1,1,2,2,3,3-hexafluoropropane-1,3-disulfonylamide anion (2) were investigated. In these solids, the cations are surrounded by four anions around their C5 axis, and stacking of these local structures forms two kinds of assembled structures. In the salts with even n (1, 1 b, and 1 d), the cation and anion are arranged alternately to form mixed-stack columns in the crystal.
