Article Synopsis
  • The study investigates the medicinal properties of two lily species (LB and LL) compared to a food-only variety (LD) to identify the active components responsible for treatment efficacy.
  • Using metabolome and transcriptome analyses, significant differences were found in metabolites, with 318 and 298 differential metabolites identified between LD-LB and LD-LL groups, respectively.
  • Results indicate that steroidal saponins and steroidal alkaloids are likely key functional components in LB and LL, which can inform future research and development in traditional medicine.

Acidity is a key factor controlling fruit flavor and quality. In a previous study, combined transcriptome and methylation analyses identified a P3A-type ATPase from apple (Malus domestica), MdMa11, which regulates vacuolar pH when expressed in Nicotiana benthamiana leaves. In this study, the role of MdMa11 in controlling fruit acidity was verified in apple calli, fruits, and plantlets.

Article Synopsis
  • This study explores how sugars and acids contribute to the flavor and quality of fleshy fruits, particularly apples during their development.
  • Researchers used advanced techniques like ATAC-seq and RNA-seq to analyze genome-wide chromatin accessibility, leading to the creation of a transcriptional regulatory network related to sugar and acid accumulation.
  • The findings identify key transcription factors that regulate the metabolism of sugars and acids in apples, which could help improve apple quality in the future.

Malic acid is a major organic acid component of apples and a crucial determinant of fruit organoleptic quality. A candidate gene for malic acid content, designated MdMa1, was previously identified in the Ma locus, which is a major quantitative trait locus (QTL) for apple fruit acidity located on the linkage group 16. Region-based association mapping to detect candidate genes in the Ma locus identified MdMa1 and an additional MdMYB21 gene putatively associated with malic acid.

Acidity is a key determinant of fruit organoleptic quality. Here, a candidate gene for fruit acidity, designated MdMYB123, was identified from a comparative transcriptome study of two Ma1Ma1 apple (Malus domestica) varieties, "Qinguan (QG)" and "Honeycrisp (HC)" with different malic acid content. Sequence analysis identified an A→T SNP, which was located in the last exon, resulting in a truncating mutation, designated mdmyb123.

Background: Due to the lack of evidence and inconsistency of sex differences in Heart failure (HF) in the Chinese population, this study aimed to compare sex differences in functional capacity and quality of life (QoL) between women and men after standard HF medications therapies, and analyze whether sex differences were associated with the composite endpoints of all-cause mortality or HF-related hospitalization and cardiac event-free survival rate in Chinese patients with HF.

Methods: This was a 1-year longitudinal study. Participants included patients with HF from March 2017 to December 2018.

Acidity is an important factor influencing the organoleptic quality of apple fruits. In this study, an apple pyrophosphate-energized proton pump (PEPP) gene was isolated and designated MdMa12. On the basis of a phylogenetic analysis in Rosaceae species, PEPP genes were divided into three groups, with apple PEPP genes most closely related to pear PEPP genes.

Organic acids and soluble sugars are the major determinants of fruit organoleptic quality. Additionally, DNA methylation has crucial regulatory effects on various processes. However, the epigenetic modifications in the regulation of organic acid and soluble sugar accumulation in apple fruits remain uncharacterized.

The novel Coronavirus-2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) in March 2020, impacting the lifestyles, economy, physical and mental health of individuals globally. This study aimed to test the model triggered by physical symptoms resembling COVID-19 infection, in which the need for health information and perceived impact of the pandemic mediated the path sequentially, leading to adverse mental health outcomes. A cross-sectional research design with chain mediation model involving 4612 participants from participating 8 countries selected via a respondent-driven sampling strategy was used.

The coronavirus disease (COVID-19) pandemic has impacted the economy, livelihood, and physical and mental well-being of people worldwide. This study aimed to compare the mental health status during the pandemic in the general population of seven middle income countries (MICs) in Asia (China, Iran, Malaysia, Pakistan, Philippines, Thailand, and Vietnam). All the countries used the Impact of Event Scale-Revised (IES-R) and Depression, Anxiety and Stress Scale (DASS-21) to measure mental health.

Vernakalant is a novel, relatively atrial-selective antiarrhythmic agent. Despite its good efficacy profile and rapid onset of action, there was still controversial evidence regarding vernakalant-related adverse events. We searched PubMed and Embase for studies that compared intravenous vernakalant with placebo or antiarrhythmic agents in patients with recent-onset atrial fibrillation (AF) lasting no more than 7 days.

Vanillic acid (VA), one of the phenolic acids metabolized by anthocyanidins, can modulate vascular reactivity by reducing the superoxide. We investigated that VA alleviated fatty acid-induced oxidative stress and clarified its potential mechanisms in human umbilical vein endothelial cells (HUVECs). Our results showed that VA reduced the production of reactive oxygen species and malondialdehyde levels.

Catechin and epicatechin are flavan-3-ols, with (+)-catechin (C) and (-)-epicatechin (EC) being the most common optical isomers found in nature. In this study, we found that C and EC showed notable inhibitory activity against a-glucosidase (AGH), and that both inhibition activities reversible and competitive. Additionally, we observed that C and EC quenched the intrinsic fluorescence of AGH through a static quenching mechanism, and that the electrostatic force was the predominant driving factor in the binding reaction.

Protocatechuic acid (PCA, 3,4-dihydroxybenzoic acid), the main metabolite of anthocyanins, is widely distributed in fruits and vegetables and has been reported to possess a strong antioxidant activity. Herein, we aimed to investigate the protective effect of PCA against high palmitic-acid (PA)-induced oxidative damage and the underling molecular mechanisms in human umbilical vein endothelial cells (HUVECs). PCA reduced the levels of intracellular reactive oxygen species and malondialdehyde and increased the activities of endogenous antioxidant enzymes, including superoxide dismutase, glutathione peroxidase 1, and heme oxygenase 1 (HO-1).

Article Synopsis
  • A study was conducted on Chinese elderly patients at high risk for cardiovascular issues to explore the link between albuminuria (measured through albumin-to-creatinine ratio, ACR) and major cardiovascular events, including mortality.
  • Over a median follow-up of 56 months, higher urinary ACR was linked to nearly double the all-cause mortality and triple the heart failure hospitalizations compared to those with lower ACR.
  • Despite these findings, no significant differences in major adverse cardiovascular events were observed across different ACR levels, indicating the need for further research focused on age-specific ACR cutoffs.*
