The focus of this review is placed on the chemical structures from species genus Talaromyces reported with reference to their biological activities. 221 secondary metabolites, including 43 alkaloids and peptides, 88 esters, 31 polyketides, 19 quinones, 15 steroid terpenoids, 25 other structure type compounds, have been included, 66 references are cited.
The fungus Clonostachys rosea is widely distributed all over the world. destructive force of this fungus, as a biological control agent, very strong to lots plant pathogenic fungi. As part ongoing search for antibiotics from fungi obtained soil samples, secondary metabolites C. YRS-06 were investigated. Through efficient bioassay-guided isolation, three new bisorbicillinoids possessing open-ended cage structures, tetrahydrotrichodimer ether (1) and dihydrotrichodimer A B (2 3), 12 known...
Abstract Elephant grass (2 n = 4 x 28; Cenchrus purpureus Schumach.), also known as Napier grass, is an important forage and potential energy crop in tropical subtropical regions of Asia, Africa America. However, no study has yet reported a genome assembly for elephant at the chromosome scale. Here, we report high‐quality chromosome‐scale with total size 1.97 Gb 1.5% heterozygosity rate, obtained using short‐read sequencing, single‐molecule long‐read sequencing Hi‐C conformation capture....
ABSTRACT Polypropylene (PP) membranes show promising applications in electric and biomedical fields. However, the residue of Z–N catalyst system would decline their electrical properties, limiting practical applications. To explore transition migration propylene polymerization, as‐synthesized PP granules are extracted with polar solvent (ethanol) nonpolar ( n ‐hexane) respectively. The extracts quantitatively analyzed 1 H NMR technique. results demonstrate that donors low‐molecular‐weight...
Abstract Background Titanium‐zirconium alloy (TiZr1317) is a new material used for biological implants. There are several studies on the effects of TiZr implants characteristics human bone mesenchymal stem cells (hBMSCs). Purpose The purpose this study was to investigate responses hBMSCs implant holes affected by physicochemical properties oral (Ti SLA , Ti SLActive and ). Materials Methods Grade 4 (13‐17% Zr) substrates were modified sand‐blasted large‐grit acid‐etched (SLA) or hydrophilic...
We investigated the question of whether brain can be adversely affected after 4 weeks by whole-body exposure with different doses of<sup>56</sup>Fe ion irradiation and experiments showed that resulted in significant impairment cognitive performance.
Vegetation responses to climate change are typically nonlinear with varied time effects, yet current research lacks comprehensiveness and precise definitions, hindering a deeper understanding of the underlying mechanisms. This study used mountain-type Qilian Mountains National Park (QMNP) in China as case systematically investigate characteristics patterns these effects using generalized additive model (GAM) based on MODIS-NDVI, seasonal temperature, precipitation data. The results show that...
Fragile dryland ecosystems are at increased risk of destabilization with the frequent occurrence hydro-meteorological anomalies. Recent studies assessing ecosystem stability have primarily considered precipitation (PRE) and often neglected response to soil moisture (SM) potential evapotranspiration (PET). Meanwhile, mechanisms that influence spatial variability require further investigation. Based on Normalized Difference Vegetation Index (NDVI) from 2001 2022 responses changes in PRE, SM...
Objective To understand the status of radiation therapy in sichuan province, analysis development level radiotherapy past five years provide reference for rational allocation resources promote healthy radiotherapy. Methods With to surveys carried out by other provinces and survey province 2009, determine schemes, projects. The covers all medical units adopt way combination questionnaire on-the-spot visiting. Results There is a big progress basic condition, treatment equipment,...
Abstract Drought is the major climate disaster experienced by dryland mountains. However, altitudinal differentiation of forest resilience to drought and its dominant factors in mountains largely unknown, which crucial predict whether primary forests will collapse under future global warming. In this study, we selected leaf area index (LAI) standardized precipitation evapotranspiration (SPEI), fitted curves based on intensity recovery time, calculated curve define along elevation zones...
Abstract BackgroundTrimethylamine N-Oxide (TMAO) has been shown to be an independent risk factor for cardiovascular disease. Our aim is study the effects of TMAO on type 2 diabetes mellitus-coronary heart disease and explore its mechanism.MethodsA total 50 healthy controls , T2DM patients combined with CHD were enrolled. Serum samples collected detect glucose, myocardial enzyme spectrum level. The 16S rRNA gene sequencing analyzed diversity intestinal flora. Taking ZDF rat as experimental...
Soil quality is very important to the and safety of agricultural products, remediation heavy metal contaminated soil a long-term work. At present, common method add materials so that metals are solidified in cannot be absorbed by plants. In this study, hydroxyapatite(HAP) humic acid(HA) were selected as combine into five treatment groups. The pH, electrical conductivity(EC), cation exchange capacity(CEC), organic matter(SOM), Diethylenetriamine pentaacetic acid(DTPA) extraction concentration...
Abstract Using spatial autocorrelation methods we explores the and temporal differences in response of soil water conservation to ecosystem fragmentation during period between 1990 2019 Qilian Mountain National Park (QMNP) China. We found that degree has decreased over past 30 years, improving capacity park's ecosystems. However, relationship two varied temporally also exhibited a variety patterns. These were due heterogeneity ecosystems, forms different ecosystems Moreover, there impact...
<title>Abstract</title> <bold>Background</bold>: Glioma is the most common brain tumor disease. Magnetic resonance can help clinical diagnosis according to location of glioma and degree malignancy, in which segmentation site plays an important role for clinicians. The work manual very time-consuming cumbersome, therefore automatic efficient methods are necessary. <bold>Methods</bold>: This paper proposed AIUNet give a more glioma, where new block---Attention based Inception Block (AI Block),...
Abstract Ferrihydrite often precipitates with humic acid in natural ways, affecting the fate of lead ions, stabilization and aging process ferrihydrite. A series 2-line ferrihydrite-humic (Fh-HA) varying C loadings has been prepared, morphology surface properties Fh-HA organo-minerals have characterized, adsorption property Pb ions onto studied. The results indicated a strong interference HA to Fh dominated mineral phase all samples, but increasing C/Fe molar ratios crystallinity gradually...
