Occurrence of short- and ultra-short chain PFAS in drinking water from Flanders (Belgium) and implications for human exposure.

SHORT: and ultra-short chain perfluoroalkyl substances (S- and US-PFAS) are alternatives for the long-chain PFAS which have been more regulated over time. They are highly mobile in the environment and can easily reach drinking water sources which can become an important human exposure route. Furthermore, there have been growing concerns about the presence of PFAS in Flanders.

Changes in microbial dynamics and fermentation characteristics of alfalfa silage: A potent approach to mitigate greenhouse gas emission through high-quality forage silage.

Assessment of Welfare Problems in Broilers: Focus on Musculoskeletal Problems Associated with Their Rapid Growth.

The growth of the broiler industry has been accompanied with concerns over the environmental and social impacts on intensive production systems, as well as the welfare of the animals themselves. As a result, since the 2000s, there has been growing interest in alternative production systems that improve animal welfare and sustainability. In this context, it is important to prioritize the welfare of broilers in commercial production systems and to use reliable welfare indicators to provide consumers with information about the welfare of the animals they consume.

Childlessness, Social Network Profiles in Midlife and Late Adulthood, and Their Implications for Subjective Well-Being.

Within-Family Differences in Intergenerational Contact: The Role of Gender Norms in a Patrilineal Society.

Intergenerational contact is important to older adults' quality of life, but less is known about within-family differences in older parents' contact between sons and daughters, especially in countries with patrilineal traditions. Applying latent profile analysis to data on 3,228 Korean older adults' frequency of meeting and communication with each of their children, this study identified within-family patterns of intergenerational contact. Nearly half of parents exhibited gender-balanced patterns of meeting across children, while 13% reported "more frequent contact with daughters" and 39% reported "more frequent contact with sons.

Molecular mechanism controlling anthocyanin composition and content in radish plants with different root colors.

Radish (Raphanus sativus) roots exhibit various colors that reflect their anthocyanin compositions and contents. However, the details of the mechanism linking the expression of anthocyanin biosynthesis and their transcriptional regulators to anthocyanin composition in radish roots remained unknown. Here, we characterized the role of the anthocyanin biosynthetic enzyme flavonoid 3'-hydroxylase (RsF3'H), together with the R2R3 MYB transcription factor (TF) RsMYB1 and the basic helix-loop-helix (bHLH) TF TRANSPARENT TESTA 8 (RsTT8), in four radish plants with different root colors: white (W), deep red (DR), dark purple (DP), and dark greyish purple (DGP).
