Cardiac fibrosis is associated with most cardiac diseases. Fibrosis is an accumulation of excessive extracellular matrix proteins (ECM) synthesized by cardiac fibroblasts and myofibroblasts. Fibroblasts are the most prevalent cell type in the heart, comprising 75% of cardiac cells. Myofibroblasts are hardly present in healthy normal heart tissue, but appear abundantly in diseased hearts. Cardiac fibroblasts are activated by a variety of pathological stimuli, such as myocardial injury, oxidative stress, mechanical stretch, and elevated autocrine-paracrine mediators, thereby undergoing proliferation, differentiation to myofibroblasts, and production of various cytokines and ECM proteins. A number of signaling pathways and bioactive molecules are involved …
Are Baby Boomers Who Care For Their Older Parents Planning For Their Own Future Long-Term Care Needs?, Alison Kleppinger, Julie T. Robison
Are Baby Boomers Who Care For Their Older Parents Planning For Their Own Future Long-Term Care Needs?, Alison Kleppinger, Julie T. Robison

A rapidly expanding number of baby boomers provide care to aging parents. This study examines associations between caregiver status and outcomes related to awareness and anticipation of future long-term care (LTC) needs using 2007 Connecticut Long-Term Care Needs Assessment survey data. Baby boomers who were adult child caregivers (n = 353) vs. baby boomers who were not (n = 1242) were more likely to anticipate some future LTC needs and to have considered certain financing strategies. Although baby boomer adult child caregivers more readily anticipate some future LTC needs, they are not taking specific actions. It is important to address …

Osteoporosis is a severe condition in postmenopausal women and a common cause of fracture. Osteoporosis is a complex disease with a strong genetic impact, but susceptibility is determined by many genes with modest effects and environmental factors. Only a handful of genes consistently associated with osteoporosis have been identified so far. Inflammation affects bone metabolism by interfering with the interplay between bone resorption and formation, and many inflammatory mediators are involved in natural bone remodeling. The cytokine macrophage migration inhibitory factor (MIF) has been shown to affect bone density in rodents, and polymorphisms in the human MIF promoter are associated …
Mitochondria-Centric Activation Induced Cell Death Of Cytolytic T Lymphocytes And Its Implications For Cancer Immunotherapy, Arvind Chhabra
Mitochondria-Centric Activation Induced Cell Death Of Cytolytic T Lymphocytes And Its Implications For Cancer Immunotherapy, Arvind Chhabra

Premature death of the adoptively transferred cytolytic T lymphocytes (CTL) by means of activation induced cell death (AICD) represents one of the major constraints in devising an effective anti-cancer immune intervention strategy. Understanding the mechanism of AICD is, therefore, critical for developing methods to interfere with this death process. Although the existing paradigm on AICD centers around the initiation of the cascade of events originating from the engagement of death receptors leading to the activation of effector caspases and eventually resulting in cell death, recent findings have questioned the universal role of caspases as the cell death executioners. We here …

Rationale—Cardiac fibrosis contributes to pathogenesis of atrial fibrillation (AF), which is the most sustained arrhythmia and a major cause of morbidity and mortality. Although it has been suggested that Ca2+ signals are involved in fibrosis promotion, the molecular basis of Ca2+ signaling mechanisms and how Ca2+ signals contribute to fibrogenesis remain unknown.
Objective—To determine the molecular mechanisms of Ca2+-permeable channel(s) in human atrial fibroblasts, and to investigate how Ca2+ signals contribute to fibrogenesis in human AF.
Methods and Results—We demonstrate that the transient receptor potential melastatin related 7 (TRPM7) is the molecular basis of the major Ca2+-permeable channel in human …

In contrast to many years of important research and clinical attention to the pathological effects of alcohol (ethanol) abuse, the past several decades have seen the publication of a number of peer-reviewed studies indicating beneficial effects of light-moderate, non-binge consumption of varied alcoholic beverages, as well as experimental demonstrations that moderate alcohol exposure can initiate typically cytoprotective mechanisms. A considerable body of epidemiology associates moderate alcohol consumption with significantly reduced risks of coronary heart disease and, albeit currently a less robust relationship, cerebrovascular (ischemic) stroke. Experimental studies with experimental rodent models and cultures (cardiac myocytes, endothelial cells) indicate that moderate …
