Too Little Sleep Destroys DNA?
I talk to my patients about the danger of not sleeping all the time. Unfortunately, it’s a common problem that affects 75 million Americans. People who don’t sleep, or sleep poorly, have up to 400% more accidents that those who get a good night’s rest. Not getting enough sleep also increases your risk of developing chronic diseases. Studies, including a large meta-analysis of 470,000 adults, found that those who slept less than six hours developed a:1,2,3,4,5 48% increase in the incidence of coronary heart disease 30% increased risk of dementia 15% increase in the incidence of stroke 50% cancer risk 17% higher risk ...

Perlecan regulates pericyte dynamics in the maintenance and repair of the blood-brain barrier
Ischemic stroke causes blood–brain barrier (BBB) breakdown due to significant damage to the integrity of BBB components. Recent studies have highlighted the importance of pericytes in the repair process of BBB functions triggered by PDGFRβ up-regulation. Here, we show that perlecan, a major heparan sulfate proteoglycan of basement membranes, aids in BBB maintenance and repair through pericyte interactions. Using a transient middle cerebral artery occlusion model, we found larger infarct volumes and more BBB leakage in conditional perlecan (Hspg2)-deficient (Hspg2–/–-TG) mice than in control mice. Con...

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Autophagy after subarachnoid hemorrhage: Can cell death be good?
Abstract Autophagy is a prosurvival, reparative process that maintains cellular homeostasis through lysosomal degradation of selected cytoplasmic components and programmed death of old, dysfunctional, or unnecessary cytoplasmic entities. According to growing evidence, autophagy shows beneficial effects following subarachnoid hemorrhage (SAH). SAH is considered one of the most devastating forms of stroke. Though autophagy is prosurvival and aids in repair, deregulated or excessive autophagy results in increased cell death, more brain injury, and worse outcome. The aim of this review lies in revealing the pathophysi...

Reflections on the Future of Medicine
Recently, I traveled through China. I climbed mountains, hiked through forests, crossed deep valleys. I visited cities of every size. I floated across lakes and traveled beautiful shorelines churning with life. As a man of a certain age, I began to compare the permanence of the timeless landscape with the evanescence of my own existence. Yet, as a scientist, I knew these reflections were flawed. Scientists are trained to think in terms of aeons, millenia, and lifetimes. Consider the paradox. Is it the solid mountain or fragile the forest that is permanent? Is it the massive shoreline cliffs or the teeming shore life that...

Rehabilitation Improves Behavioral Recovery and Lessens Cell Death Without Affecting Iron, Ferritin, Transferrin, or Inflammation After Intracerebral Hemorrhage in Rats
Conclusions. Rehabilitation is an effective behavioral and neuroprotective strategy for ICH. Neither effect appears to stem from influencing iron toxicity or inflammation. Thus, additional work must identify underlying mechanisms to help further therapeutic gains.
