Auxin fluctuation and PIN polarization in moss leaf cell reprogramming.

Plant Cell Physiol

January 2025

Graduate Institute of Biochemistry, National Chung Hsing University, No. 145, Xingda Rd., South Dist., Taichung 40227, Taiwan, R.O.C.

Auxin and its PIN-FORMED (PIN) exporters are essential for tissue repair and regeneration in flowering plants. To gain insight into the evolution of this mechanism, we investigated their roles in leaves excised from Physcomitrium patens, a bryophyte known for its remarkable cell reprogramming capacity. We used various approaches to manipulate auxin levels, including exogenous application, pharmacological manipulations, and auxin biosynthesis mutants.

Oxidative stress is a biological principle affecting all life on Earth and is also an important factor in the pathogen-host relationship. The pathogenic free-living amoeba has several pathways to cope with reactive oxygen species and the damage that they cause. In this study, we aimed to provide a comprehensive analysis of the amoeba's response to different sources of oxidative stress.

Cytochrome P450 (CYP) 3A4 plays a major role in drug metabolism. Its activity could be determined by non-invasive and cost-effective assays, such as breath analysis, for the personalised monitoring of drug response. For the first time, we identify an isotopically unlabelled CYP3A4 substrate, tolterodine that leads to the formation of a non-toxic volatile metabolite, acetone, which could potentially be applied to monitor CYP3A4 activity in humans.

Navigating life's twists and turns: characteristics of life events across adulthood.

Eur J Ageing

January 2025

Department of Developmental and Educational Psychology, University of Vienna, Liebiggasse 5, 1010, Vienna, Austria.

This study examines whether there are age-related differences in the experience of life events across adulthood. We hypothesized that older adults would report life events that are less anticipated, less normative, less controllable, less positive, and more strenuous than younger adults due to increasing developmental losses and decreasing gains. We investigated how age (linear, quadratic, and cubic) relates to life-event characteristics by comparing different events and analyzing the same events across individuals, to distinguish between the effects observed across life events and those that emerge after accounting for the specific life event in question.

Trajectory of Cardiogenic Dementia: A New Perspective.

J Cell Mol Med

January 2025

Department of Research & Development, AFNP Med, Wien, Austria.

The functions of the heart and brain are closely linked and essential to support human life by the heart-brain axis, which is a complex interconnection between the heart and brain. Also, cardiac function and cerebral blood flow regulate the brain's metabolism and function. Therefore, deterioration of cardiac function may affect cognitive function and may increase the risk of dementia.

Mechanisms of Lipid-Associated Macrophage Accrual in Metabolically Stressed Adipose Tissue.

Bioessays

January 2025

Gottfried Schatz Research Center for Cell Signaling, Metabolism and Aging, Division of Cell Biology, Histology and Embryology, Medical University of Graz, Graz, Austria.

Adipose tissue (AT) inflammation, a hallmark of the metabolic syndrome, is triggered by overburdened adipocytes sending out immune cell recruitment signals during obesity development. An AT immune landscape persistent throughout weight loss and regain constitutes an immune-obesogenic memory that hinders long-term weight loss management. Lipid-associated macrophages (LAMs) are emerging as major players in diseased, inflamed metabolic tissues and may be key contributors to an obesogenic memory in AT.

The aim of this work was to develop and validate a rapid dispersive-solid-phase extraction method for the quantification of pyrrolizidine alkaloids (PA) from plant extracts. The method was focused on the significant removal of the intricate matrix to ensure good sensitivity for the subsequent instrumental analysis of PA. This was achieved by employing nano-zirconium silicate (NZS) as a dispersive-SPE sorbent.

Ensuring the provision of safe drinking water necessitates thorough monitoring of microbial water quality. While traditional culture-based enumeration of bacterial indicators has served as the gold standard in compliance monitoring since the late 19th century, recent advancements in microbial sensor technology, driven by automation and digitalization, are revolutionizing on-site monitoring capabilities. These innovations offer unparalleled potential for automated, high temporal frequency monitoring with remote, real-time data transmission.
