Repetitive sequences are recognized for their roles in plant genome organization and function. Mobile elements are notable repeatome sequences due to their intrinsic mutagenic potential, which is related to the origin of adaptive novelties. Understanding the genomic organization and dynamics of the repeatome is fundamental to enlighten their role in plant genome evolution.

We have previously developed a transcription-based bacterial three-hybrid (B3H) assay as a genetic approach to probe RNA-protein interactions inside of E. coli cells. This system offers a straightforward path to identify and assess the consequences of mutations in RBPs with molecular phenotypes of interest.

Heart failure (HF) is a conundrum in that, current therapies only slow the progression of the disease. We posit, if the causal mechanism were targeted, progression of the disease could be stopped and potentially reversed. We hypothesize that insufficient myocardial blood flow (MBF) produces minute areas of ischemia, that lead to an accumulating injury culminating in HF.

Intestinal ischemia-reperfusion (I/R) injury occurs under various surgical or disease conditions, where tissue hypoxia followed by reoxygenation results in the production of oxygen radicals and inflammatory mediators. These substances can target the endothelial barrier, leading to microvascular leakage. In this study, we induced intestinal I/R injury in mice by occluding the superior mesenteric artery, followed by removing the clamp to resume blood circulation.

In this paper, we present a new computational framework for the simulation of airway resistance, the fraction of exhaled nitric oxide, and the diffusion capacity for nitric oxide in healthy and unhealthy lungs. Our approach is firstly based on a realistic representation of the geometry of healthy lungs as a function of body mass, which compares well with data from the literature, particularly in terms of lung volume and alveolar surface area. The original way in which this geometry is created, including an individual definition of the airways in the first seven generations of the lungs, makes it possible to consider the heterogeneous nature of the lungs in terms of perfusion and ventilation.
