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.

We report a case of successful treatment of probable invasive pulmonary aspergillosis due to A. lentulus and polymicrobial infection with Pseudomonas aeruginosa in a patient with relapsing granulomatosis with polyangiitis and recent high-dose steroid therapy.

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...

In recent years the research community has made some progress towards the use of cell therapies to treat fibrosis in lung tissue, the basis for a number of ultimately fatal conditions that present cannot be effectively controlled. Fibrosis is a disruption of the structure of tissue, the formation of scar-like structures that degrade tissue function. This line of research may soon be overtaken by the use of senolytic treatments to remove senescent cells, given that senescent cells appear to be a significant cause of the age-related failures in regenerative processes that cause fibrosis. Nonetheless, prior to recent work on ...

SummaryThe anti-inflammatory and antibacterial mechanisms of bone marrow mesenchymal stem cells (MSCs) ameliorating lung injury in chronic obstructive pulmonary disease (COPD) mice induced by cigarette smoke andHaemophilus Parainfluenza (HPi) were studied. The experiment was divided into four groupsin vivo: control group, COPD group, COPD+HPi group, and COPD+HPi+MSCs group. The indexes of emphysematous changes, inflammatory reaction and lung injury score, and antibacterial effects were evaluated in all groups. As compared with control group, emphysematous changes were significantly aggravated in COPD group, COPD+HPi group ...

Authors: Azargoon A, Negahdari B Abstract Respiratory diseases, such as chronic obstructive pulmonary disease (COPD), pulmonary hypertension and lung fibrosis, are yet a major challenge in the world and they result in irreversible structural lung damage. Lung transplantation as the only therapeutic option face some major challenges like graft rejection and cancer, arising as a result of immunosuppression. A low survival rate faced by lung transplantation patients is presently limited to approximately 5 years. Lungs shortage therefore calls for a mechanism that would increase the availability of suitable orga...

In this study, we focused on two pathways of cardiomyocytes or heart cells: the Hippo pathway, which is involved in stopping renewal of adult cardiomyocytes, and the dystrophin glycoprotein complex (DGC) pathway, essential for cardiomyocyte normal functions." Previous work had hinted that components of the DGC pathway may somehow interact with members of the Hippo pathway. The researchers genetically engineered mice to lack genes involved in one or both pathways, and then determined the ability of the heart to repair an injury. These studies showed for the first time that dystroglycan 1, a component of the DGC ...

In this study, researchers analysed data of millions of British patients between 1995 and 2015 to see if this claim held true. They tracked people who were obese at the start of the study, defined as people with a body mass index (BMI) of 30 or more, who had no evidence of heart disease, high blood pressure, high cholesterol or diabetes at this point. They found these people who were obese but "metabolically healthy" were at higher risk of developing heart disease, strokes and heart failure than people of normal weight. No such thing as 'fat but fit', major study finds Several studies in the pas...
