An Adaptive SCG-ECG Multimodal Gating Framework for Cardiac CTA.

Cardiovascular disease (CVD) is the leading cause of death worldwide. Coronary artery disease (CAD), a prevalent form of CVD, is typically assessed using catheter coronary angiography (CCA), an invasive, costly procedure with associated risks. While cardiac computed tomography angiography (CTA) presents a less invasive alternative, it suffers from limited temporal resolution, often resulting in motion artifacts that degrade diagnostic quality.

Genome-wide analysis revealed the stepwise origin and functional diversification of HSDs from lower to higher plant species.

Hydroxysteroid dehydrogenase (HSDs) is an oil-body sterol protein (steroleosin) with an NADP(H) binding domain that belongs to the short-chain dehydrogenase/reductase (SDR) superfamily. There are numerous studies on the characterization of in plants. However, thus far, the evolutionary differentiation and divergence analysis of these genes remain to be explored.

Abscisic acid inhibits primary root growth by impairing ABI4-mediated cell cycle and auxin biosynthesis.

Cell cycle progression and the phytohormones auxin and abscisic acid (ABA) play key roles in primary root growth, but how ABA mediates the transcription of cell cycle-related genes and the mechanism of crosstalk between ABA and auxin requires further research. Here, we report that ABA inhibits primary root growth by regulating the ABA INSENSITIVE4 (ABI4)-CYCLIN-DEPENDENT KINASE B2;2 (CDKB2;2)/CYCLIN B1;1 (CYCB1;1) module-mediated cell cycle as well as auxin biosynthesis in Arabidopsis (Arabidopsis thaliana). ABA induced ABI4 transcription in the primary root tip, and the abi4 mutant showed an ABA-insensitive phenotype in primary root growth.

Seed Dormancy and Longevity: A Mutual Dependence or a Trade-Off?

Seed dormancy is an important agronomic trait in cereals and leguminous crops as low levels of seed dormancy during harvest season, coupled with high humidity, can cause preharvest sprouting. Seed longevity is another critical trait for commercial crop propagation and production, directly influencing seed germination and early seedling establishment. Both traits are precisely regulated by the integration of genetic and environmental cues.

Repressors: the gatekeepers of phytohormone signaling cascades.

Coordinated phytohormone signal transduction, in which repressors are the key players, is essential to balance plant development and stress response. In the absence of phytohormones, repressors interplay to terminate the transcription of phytohormone-responsive genes. For phytohormone signal transduction, degradation or inactivation of the repressors is a prerequisite, a process in which proteasomal degradation or protein modifications, such as phosphorylation, are involved.

Evaluation of duplicated reference genes for quantitative real-time PCR analysis in genome unknown hexaploid oat ( L.).

Background: Oat ( L.), a hexaploid crop with unknown genome, has valuable nutritional, medicinal and pharmaceutical uses. However, no suitable RGs (reference genes) for qPCR (quantitative real-time PCR) has been documented for oat yet.

Effect of poly-γ-glutamic acid on hydration and structure of wheat gluten.

In recent years, hydrocolloids have been used extensively as enhancers in dough products. However, studies on the effect of hydrophilic polymers on wheat gluten (WG) within the dough are scarce. In the present study, poly-γ-glutamic acid (γ-PGA), a new and healthy food additive, was added to the WG to investigate its effect on hydration, rheological properties, and structures of WG.

Combined Kinetin and Spermidine Treatments Ameliorate Growth and Photosynthetic Inhibition in by Up-Regulating Antioxidant and Nitrogen Metabolism under Cadmium Stress.

Pot experiments were conducted to investigate the probable beneficial role of the individual as well as combined application of kinetin (50 μM Kn) and spermidine (200 μM Spd) on under cadmium (Cd) stress. Cd treatment reduced growth by declining the content of chlorophylls and carotenoids, photosynthesis, and gas exchange parameters. Exogenously, Kn and Spd application enhanced the photosynthetic parameters and up-regulated the antioxidant system by improving the activities of antioxidant enzymes and the content of non-enzymatic components.

Influence of Exogenous Salicylic Acid and Nitric Oxide on Growth, Photosynthesis, and Ascorbate-Glutathione Cycle in Salt Stressed .

The present study was carried out to investigate the beneficial role of exogenous application of salicylic acid (1 mM SA) and nitric oxide (100 μM NO) in preventing the oxidative damage in triggered by salinity stress. Salinity (100 mM NaCl) stress reduced growth, biomass accumulation, chlorophyll synthesis, photosynthesis, gas exchange parameters, and photochemical efficiency (Fv/Fm) significantly. Exogenous application of SA and NO was affective in enhancing these growth and photosynthetic parameters.

Characterization CSMD1 in a large set of primary lung, head and neck, breast and skin cancer tissues.

The Cub and Sushi Multiple Domains-1 (CSMD1) is a tumor suppressor gene on 8p23.2, where allelic loss is both frequent and associated with poor prognosis in head and neck squamous cell carcinoma (HNSCC). To understand the extent of CSMD1 aberrations in vivo, we characterized 184 primary tumors from the head and neck, lung, breast and skin for gene copy number and analyzed expression in our HNSCCs and lung squamous cell carcinomas (SCCs).
