Transfer RNA-derived fragment production in calves challenged with or co-infected with bovine viral diarrhea virus and in several tissues and blood.

Understanding the molecular mechanisms underlying immune response can allow informed decisions in drug or vaccine development, and aid in the identification of biomarkers to predict exposure or evaluate treatment efficacy. The objective of this study was to identify differentially expressed transfer RNA-derived fragments (tRFs) in calves challenged with () or co-infected with and bovine viral diarrhea virus (BVDV). Serum, white blood cells (WBC), liver, mesenteric lymph node (MLN), tracheal-bronchial lymph node (TBLN), spleen, and thymus were collected from Control ( = 2), (MB;  = 3), and co-infected (Dual; = 3) animals, and small RNAs extracted for sequencing.

Scale-dependent population drivers inform avian management in a declining saline lake ecosystem.

Shrinking saline lakes provide irreplaceable habitat for waterbird species globally. Disentangling the effects of wetland habitat loss from other drivers of waterbird population dynamics is critical for protecting these species in the face of unprecedented changes to saline lake ecosystems, ideally through decision-making frameworks that identify effective management options and their potential outcomes. Here, we develop a framework to assess the effects of hypothesized population drivers and identify potential future outcomes of plausible management scenarios on a saline lake-reliant waterbird species.

The distinct affect regulation functions of body image flexibility and inflexibility: A prospective study in adolescents and emerging adults.

Body image flexibility and inflexibility are alternative ways of responding to body image threats. Affect regulation offers a framework for understanding how these responses impact health outcomes; however, research in young people is limited. This prospective study tested two potential affect regulation functions in adolescents and emerging adults (N = 351, 66.

Analysis of isomeric mixtures by molecular rotational resonance spectroscopy.

Recent developments in molecular rotational resonance (MRR) spectroscopy that have enabled its use as an analytical technique for the precise determination of molecular structure are reviewed. In particular, its use in the differentiation of isomeric compounds-including regioisomers, stereoisomers and isotopic variants-is discussed. When a mixture of isomers, such as resulting from a chemical reaction, is analyzed, it is highly desired to be able to unambiguously identify the structures of each of the components present, as well as quantify them, without requiring complex sample preparation or reference standards.
