Research on 3D scaffolds sets new bar in lung regeneration

For the estimated 12.7 million people with chronic obstructive pulmonary disorder, the third leading cause of death in the US, innovative research efforts in the field of tissue regeneration hold promise. In end-stage lung disease, transplantation is sometimes the only viable therapeutic option, but organ availability is limited and rejection presents an additional challenge. New research focuses on lung tissue bioengineering, which involves the use of a scaffold -- or framework -- of lungs from human cadavers to engineer new lungs for patients with end-stage disease. The studies have examined multiple perspectives on the process of stripping the cellular material from these lungs and replacing it with stem cells in an effort to grow new, healthy lungs for transplantation.

Authors: Hosseinirad H, Rashidi M, Moghaddam MM, Tebyanian H, Nouraei S, Mirhosseini SA, Rasouli M, Habibian S Abstract The respiratory system is a complex group of organs in the human body, all of which are necessary in breathing. Due to its special anatomy and composition, after exposure to various damaging factors such as micro particles, carbon granules and toxic gases, the respiratory system can be affected by a variety of damage without return to its original state. Currently, the prevalence of lung diseases, including asthma, and chronic obstructive pulmonary diseases, such as emphysema, has increased remark...

We presently forget 98% of everything we experience. That will go away in favor of perfect, controllable, configurable memory. Skills and knowledge will become commodities that can be purchased and installed. We will be able to feel exactly as we wish to feel at any given time. How we perceive the world will be mutable and subject to choice. How we think, the very fundamental basis of the mind, will also be mutable and subject to choice. We will merge with our machines, as Kurzweil puts it. The boundary between mind and computing device, between the individual and his or her tools, will blur. Over the course of the ...

In this study, we investigate mitochondrial energetics and mtDNA methylation in senescent cells, and evaluate the potential of humanin and MOTS-c as novel senolytics or SASP modulators that can alleviate symptoms of frailty and extend health span by targeting mitochondrial bioenergetics. Exercise versus the Hallmarks of Aging https://www.fightaging.org/archives/2018/06/exercise-versus-the-hallmarks-of-aging/ The paper I'll point out today walks through the ways in which exercise is known to beneficially affect the Hallmarks of Aging. The Hallmarks are a list of the significant causes of aging that I dis...

In January, 2018, Academic Press published my bookPrecision Medicine and the Reinvention of Human Disease. This book has an excellent " look inside " at itsGoogle book site, which includes the Table of Contents. In addition, I thought it might be helpful to see the topics listed in the Book's index.

Transplantation of bone marrow mesenchymal stem cells (MSCs) has been identified as one such possible strategy for treatment of lung diseases including acute lung injury (Guan XJ., et al. 2012). Terapeutic potential of the MSCs lies in their paracrins effects with underlie their ability to enchance tissue regeneration and modulate immune responces (Rankin S.,2012).The aim of this study was to evaluate the effectiveness of transplantation of MSCs (TMSCs) on the dynamics of proinflammation cytokines (IF, IL-6), integral parameters of quality of life psychic and physic health (IPPH, IPPhH), distantion in 6-min wolking test (6...

We examined associations between mortality and accelerometer-measured PA using age-relevant intensity cutpoints in older women of various ethnicities. The results support the hypothesis that higher levels of accelerometer-measured PA, even when below the moderate-intensity threshold recommended in current guidelines, are associated with lower all-cause and CVD mortality in women aged 63 to 99. Our findings expand on previous studies showing that higher self-reported PA reduces mortality in adults aged 60 and older, specifically in older women, and at less than recommended amounts. Moreover, our findings challenge th...
