Does coronary microvascular dysfunction play a role in heart failure with reduced ejection fraction?
J Mol Cell Cardiol
January 2025
Department of Integrative Medical Sciences, Northeast Ohio Medical University. Electronic address:
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.

Institute of Neuroscience, State Key Laboratory of Neuroscience, CAS Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences, Shanghai, China.
Cochlear inner hair cells (IHCs) and outer hair cells (OHCs) require different transcription factors for their cell fate stabilization and survival, suggesting separate mechanisms are involved. Here, we found that the transcription factor Casz1 was crucial for early IHC fate consolidation and for OHC survival during mouse development. Loss of Casz1 resulted in transdifferentiation of IHCs into OHCs, without affecting OHC production.

Integr Environ Assess Manag

Industrieverband Agrar e. V. (IVA), Wissenschaft und Innovation, Frankfurt am Main, Germany.
Current publications that are shaping public perception repeatedly claim that residues of plant protection products (PPP) in the environment demonstrate gaps in assessing the exposure and effects of PPP, allegedly revealing the inability of the European regulatory system to prevent environmental contamination and damage such as biodiversity decline. The hypothesis is that environmental risk assessments rely on inappropriate predictive models that underestimate exposure and do not explicitly account for the impact of combinations of environmental stressors and physiological differences in stress responses. This article puts this criticism into context to allow for a more balanced evaluation of the European regulatory system for PPP.

Department of Translational Physiology, Infectiology and Public Health, Faculty of Veterinary Medicine, Ghent University, Merelbeke, Belgium.
Herpesviruses, a family of large enveloped DNA viruses, establish persistent infections in a wide range of hosts. This characteristic requires an intricate network of interactions with their hosts and host cells. In recent years, the interplay between herpesviruses and the epitranscriptome-chemical modifications in transcripts that may affect mRNA biology and fate-has emerged as a novel aspect of herpesvirus-host interactions.
