Organoids are three-dimensional structures that are derived from the self-organization of stem cells as they differentiate in vitro. The plasticity of stem cells is one of the major criteria for generating organoids most similar to the tissue structures they intend to mimic. Stem cells are cells with unique properties of self-renewal and differentiation. Depending on their origin, a distinction is made between pluripotent (embryonic) stem cells (PSCs), adult (or tissue) stem cells (ASCs), and those obtained by somatic reprogramming, so-called induced pluripotent stem cells (iPSCs). While most data since the 1980s have been acquired in the mouse model, and then from the late 1990s in humans, the process of somatic reprogammation has revolutionized the field of stem cell research. For domestic animals, numerous attempts have been made to obtain PSCs and iPSCs, an approach that makes it possible to omit the use of embryos to derive the cells. Even if the plasticity of the cells obtained is not always optimal, the recent progress in obtaining reprogrammed cells is encouraging. Along with PSCs and iPSCs, many organoid derivations in animal species are currently obtained from ASCs. In this study, we present state-of-the-art stem cell research according to their origins in the various animal models developed.Zinc (Zn) is an essential trace element in living organisms and plays a vital role in the regulation of both microbial virulence and host immune responses. A growing number of studies have shown that zinc deficiency or the internal Zn concentration does not meet the needs of animals and microbes, leading to an imbalance in zinc homeostasis and intracellular signalling pathway dysregulation. Competition for zinc ions (Zn2+) between microbes and the host exists in the use of Zn2+ to maintain cell structure and physiological functions. It also affects the interplay between microbial virulence factors and their specific receptors in the host. This review will focus on the role of Zn in the crosstalk between the host and microbe, especially for changes in microbial pathogenesis and nociceptive neuron-immune interactions, as it may lead to new ways to prevent or treat microbial infections.

Recovery rates after psychological treatments for anorexia nervosa are low to moderate, and in adults, no treatment outperforms any other. The aim of this study was to evaluate patient experiences of Radically open dialectical behavior therapy (RO DBT), a treatment developed for disorders related to maladaptive overcontrol.

Eleven female patients with anorexia nervosa were interviewed after either treatment completion (eight patients) or drop-out (three patients) from RO DBT. Interviews were transcribed and analyzed with inductive thematic analysis.

The analysis yielded five main themes 1) a comprehensive treatment, 2) the benefits of sharing and connecting with others, 3) growing trust, 4) moving toward valued goals - but some remain, and 5) doing well in treatment.

Patients appreciated what they described as a comprehensive treatment and holistic view of their problems, which helped them reduce both maladaptive overcontrol and eating disorder symptoms. Gradually sharing personal experiences both in- and outside therapy was described as essential and led to enhanced social connectedness.

The intervention study (Isaksson M, et al. J Behav Ther Exp Psychiatry. 71, 2021) that preceded this interview study was performed by the first, second, third, and fifth author, preregistered in the ISRCTN registry (no ISRCTN47156042 ).

This process induces an inflammatory response within AT that is resolved as lactation progresses; however, excessive and protracted lipolysis compounds the risk for metabolic and inflammatory diseases. The suppression of lipolytic action and inflammation, along with amplification of adipogenesis and lipogenesis, serve as prospective therapeutic targets for improving the health of periparturient dairy cows. Generally, the activation of cannabinoid receptors by endocannabinoids enhances adipogenesis and lipogenesis, suppresses lipolysis, and increases appetite in mammals. These biological effects of activating the endocannabinoid system open the possibility of harnessing the endocannabinoid system through nutritional intervention in dairy herds as a potential tool to improve dairy cows' health, although much is still to be revealed in this context. This review summarizes the current knowledge surrounding the components of the endocannabinoid system, elaborates on the metabolic effects of its activation, and explores the potential to modulate its activity in periparturient dairy cows.

DNA methylation age (mAge), a methylation biomarker for the aging process, might serve as a more accurate predictor of morbidity and aging status than chronological age. We evaluated the role of multiple factors, including fat deposition, cardiometabolic risk factors and lifestyle weight-loss intervention, on the deviation of mAge from chronological age (mAge deviation) or 18-month change in mAge (∆mAge). learn more In this sub-study of the CENTRAL magnetic resonance imaging weight-loss trial, we evaluated mAge by a validated 240-CpG-based prediction formula at baseline and after 18-month intervention of either low fat (LF) or mediterranean/low carbohydrate (MED/LC) diets.

Among 120 CENTRAL participants with abdominal obesity or dyslipidemia, mAge (mean ± SD 60.3 ± 7.5years) was higher than the chronological age (48.6 ± 9.3years) but strongly correlated (r = 0.93; p = 3.1 × 10

). Participants in the lowest tertile of mAge deviation from their chronological age had significantly lower waist-circumference, visceral ated (p < 0.05).

Lifestyle weight-loss intervention may attenuate mAging. Deviation of mAge from chronological age might be related to body fat distribution and glycemic control and could indicate biological age, health status and the risk for premature cardiometabolic diseases.
