Toll-like receptor 7 deficiency promotes survival and reduces adverse left ventricular remodelling after myocardial infarction

ConclusionsIn acute MI, TLR7 mediates the response to acute cardiac injury and chronic remodelling probably via modulation of post-MI scar formation and BM-derived inflammatory infiltration of the myocardium.

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

Conclusion A great deal of progress is being made in the matter of treating aging: in advocacy, in funding, in the research and development. It can never be enough, and it can never be fast enough, given the enormous cost in suffering and lost lives. The longevity industry is really only just getting started in the grand scheme of things: it looks vast to those of us who followed the slow, halting progress in aging research that was the state of things a decade or two ago. But it is still tiny compared to the rest of the medical industry, and it remains the case that there is a great deal of work yet to be done at all...

Waikar, Finnian R. Mc CauslandBackgroundMyeloperoxidase (MPO) catalyzes the formation of reactive nitrogen species and levels are elevated in patients with chronic kidney disease (CKD). Although increased oxidative stress and inflammation are associated with progression of CKD and cardiovascular disease (CVD), relationships between MPO concentration, CKD progression, CVD, and death remain unclear.Study DesignProspective cohort.Setting &Par...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

In conclusion, high-dose NR induces the onset of WAT dysfunction, which may in part explain the deterioration of metabolic health. Towards a Rigorous Definition of Cellular Senescence https://www.fightaging.org/archives/2019/11/towards-a-rigorous-definition-of-cellular-senescence/ The accumulation of lingering senescent cells is a significant cause of aging, disrupting tissue function and generating chronic inflammation throughout the body. Even while the first senolytic drugs capable of selectively destroying these cells already exist, and while a number of biotech companies are working on the productio...

Cardiac rehabilitation (CR), or “cardiac rehab,” is a multifaceted, medically supervised program proven to improve heart health and outcomes in people with certain types of cardiovascular disease. CR revolves around three major components: an individualized exercise and training program, education on topics related to heart health, and stress reduction. CR is currently recommended for the following diagnoses: angina (chest pain); heart attack with or without angioplasty or bypass surgery; heart failure with reduced ejection fraction (HFrEF); and heart surgery including heart valve procedures or heart or heart/l...

AbstractThyroid hormone levels are reduced in cardiovascular diseases and this phenomenon is associated with worse outcomes. It is unclear whether the changes in thyroid hormone bioavailability to the affected myocardium are beneficial or if this is a maladaptive response. Experimental studies from animal models of acute myocardial infarction (AMI) suggest that thyroid hormone treatment may be beneficial. There is limited data available on the use of thyroid hormones in patients with AMI and heart failure and this suggests that treatment to normalise thyroid hormone levels may be safe and potentially efficacious. Similarly...

Such patients are exposed to a higher cardiovascular risk due to severe calcification and congestive heart failure caused by volume overload, which end up in poor outcomes. Therefore, we aimed to evaluate outcomes of DD-CRF patients undergoing cardiac surgery in our institute.METHO...
