Here, I introduced the development history of crop growth models in recent decades, which included germination stage, initial stage, rapid research and development stage, deep development stage, improvement and application stage.

Omentin-1 attenuates atrial fibrillation via Src/PI3K/Akt signaling-mediated anti-fibrotic effects in cardiac fibroblasts.

Background: Atrial fibrillation (AF) is characterized by progressive atrial fibrosis, leading to increased morbidity and mortality. While the novel adipokine Omentin-1 demonstrates anti-fibrotic potential across organ systems, its role in AF pathogenesis remains unclear. This study investigates Omentin-1's therapeutic effects and the underlying mechanisms in angiotensin II (Ang II)-induced atrial fibrosis and AF.

Integrated proteogenomic characterization of localized prostate cancer identifies biological insights and subtype-specific therapeutic strategies.

Localized prostate cancer (PCa) is highly variable in their response to therapies. Although a fraction of this heterogeneity can be explained by clinical factors or genomic and transcriptomic profiling, the proteomic-based profiling of aggressive PCa remains poorly understood. Here, we profiled the genome, transcriptome, proteome and phosphoproteome of 145 cases of localized PCa in Chinese patients.

A physical derivation of high-flux ion transport in biological channel via quantum ion coherence.

Biological ion channels usually conduct the high-flux transport of 10 ~ 10 ions·s; however, the underlying mechanism is still lacking. Here, by applying the KcsA potassium channel as a typical example, and performing multitimescale molecular dynamics simulations, we demonstrate that there is coherence of the K ions confined in biological channels, which determines transport. The coherent oscillation state of confined K ions with a nanosecond-level lifetime in the channel dominates each transport event, serving as the physical basis for the high flux of ~10 ions∙s.

Structure of cryptophyte photosystem II-light-harvesting antennae supercomplex.

Cryptophytes are ancestral photosynthetic organisms evolved from red algae through secondary endosymbiosis. They have developed alloxanthin-chlorophyll a/c2-binding proteins (ACPs) as light-harvesting complexes (LHCs). The distinctive properties of cryptophytes contribute to efficient oxygenic photosynthesis and underscore the evolutionary relationships of red-lineage plastids.

Architecture of symbiotic dinoflagellate photosystem I-light-harvesting supercomplex in Symbiodinium.

Symbiodinium are the photosynthetic endosymbionts for corals and play a vital role in supplying their coral hosts with photosynthetic products, forming the nutritional foundation for high-yield coral reef ecosystems. Here, we determine the cryo-electron microscopy structure of Symbiodinium photosystem I (PSI) supercomplex with a PSI core composed of 13 subunits including 2 previously unidentified subunits, PsaT and PsaU, as well as 13 peridinin-Chl a/c-binding light-harvesting antenna proteins (AcpPCIs). The PSI-AcpPCI supercomplex exhibits distinctive structural features compared to their red lineage counterparts, including extended termini of PsaD/E/I/J/L/M/R and AcpPCI-1/3/5/7/8/11 subunits, conformational changes in the surface loops of PsaA and PsaB subunits, facilitating the association between the PSI core and peripheral antennae.

Positive feedback regulation of lncRNA PVT1 and HIF2α contributes to clear cell renal cell carcinoma tumorigenesis and metastasis.

Long noncoding RNAs (lncRNAs) have been reported to exert important roles in tumors, including clear cell renal cell carcinoma (ccRCC). PVT1 is an important oncogenic lncRNA which has critical effects on onset and development of various cancers, however, the underlying mechanism of PVT1 functioning in ccRCC remains largely unknown. VHL deficiency-induced HIF2α accumulation is one of the major factors for ccRCC.

Meteorological conditions and nonpharmaceutical interventions jointly determined local transmissibility of COVID-19 in 41 Chinese cities: A retrospective observational study.

Background: Before effective vaccines become widely available, sufficient understanding of the impacts of climate, human movement and non-pharmaceutical interventions on the transmissibility of COVID-19 is needed but still lacking.

Methods: We collected by crowdsourcing a database of 11 003 COVID-19 cases from 305 cities outside Hubei Province from December 31, 2019 to April 27, 2020. We estimated the daily effective reproduction numbers ( ) of COVID-19 in 41 cities where the crowdsourced case data are comparable to the official surveillance data.

Long non‑coding RNA‑DUXAP8 regulates TOP2A in the growth and metastasis of osteosarcoma via microRNA‑635.

Osteosarcoma (OS) is a malignant disease with high morbidity and mortality rates in children and adolescents. Evidence has indicated that long non‑coding RNAs (lncRNAs) may serve important roles in human cancer progression, including OS. In the present study, the role of lnc‑double homeobox A pseudogene 8 (DUXAP8) in the development of OS was identified.

Sunitinib inhibits PD-L1 expression in osteosarcoma by targeting STAT3 and remodels the immune system in tumor-bearing mice.

Exploring the mechanisms of the combination therapy using VEGFR-TKI and immune checkpoint inhibitors might be useful to control the development of osteosarcoma. The expression of PD-L1 and STAT3 in osteosarcoma were determined with western blot. Proliferation, migration and invasion were determined with CCK-8 and Transwell assays.

Application of multisegment injection on quantification of creatinine and standard addition analysis of urinary 5-hydroxyindoleacetic acid simultaneously with creatinine normalization.

In this paper, the development of a simple dilute-and-shoot method for quantifying urinary creatinine by CE-ESI-MS was described. The creatinine analysis time was about 7 min/sample by conventional single injection (SI) method and can be significantly reduced to less than 2 min/sample with multi-segment injection (MSI). In addition, the standard addition analysis of 5-hydroxyindole-3-acetic acid (5-HIAA) and creatinine normalization was performed within one run by the MSI technique, and the total analysis time was 14-min faster compared to the SI method for analyzing the same set of samples.

Amino-Si-rhodamines: A new class of two-photon fluorescent dyes with intrinsic targeting ability for lysosomes.

Noninvasive and specific visualization of lysosomes by fluorescence technology is critical for studying lysosomal trafficking in health and disease and for evaluating new cancer therapeutics that target tumor cell lysosomes. To date, there are two basic types of lysosomal probes whose lysosomal localization correlates with lysosomal acidity and endocytosis pathway, respectively. However, the former may suffer from pH-sensitive lysosomal localization and alkalization-induced lysosomal enzyme inactivation, and the latter need long incubation time to penetrate cell membrane due to the energy-dependency of endocytosis process.

Alzheimer's Disease Can Be Spared by Nonsteroidal Anti-Inflammatory Drugs.

Alzheimer's disease (AD) is characterized by deposits of amyloid-β protein (Aβ) in brain which become foci of inflammation. Neurons are destroyed by this inflammatory process, leading to the cognitive deficits which define AD clinical onset. Epidemiological studies indicate that nonsteroidal anti-inflammatory drugs (NSAIDs) can ameliorate this destructive process if they are started well before clinical signs develop.
