Recent Approaches for Angiogenesis in Search of Successful Tissue Engineering and Regeneration.

Recent Approaches for Angiogenesis in Search of Successful Tissue Engineering and Regeneration. Curr Stem Cell Res Ther. 2019 Nov 04;: Authors: Reddy LVK, Murugan D, Mullick M, Begum M ET, Sen D Abstract Angiogenesis plays a central role in human physiology from reproduction and fetal development to wound healing and tissue repair/regeneration. Clinically relevant therapies are needed for promoting angiogenesis in order to supply oxygen and nutrients after transplantation, thus relieving the symptoms of ischemia. Increase in angiogenesis can lead to restoration of damaged tissues, thereby leading the way for successful tissue regeneration. Tissue regeneration is a broad field that has shown the convergence of various interdisciplinary fields, wherein living cells in conjugation with biomaterials have been tried and tested on to the human body. Although there is a prevalence of various approaches that hypothesize enhanced tissue regeneration via angiogenesis, none of them have been successful in gaining clinical relevance. Hence, the current review summarizes the recent cell-based and cell free (exosomes, extracellular vesicles, micro-RNAs) therapies, gene and biomaterial-based approaches that have been used for angiogenesis-mediated tissue regeneration and have been applied in treating disease models like ischemic heart, brain stroke, bone defects and corneal defects. This review also puts forward a concise report of the pre-clinical and clinical studies...

Publication date: Available online 4 December 2019Source: Interdisciplinary NeurosurgeryAuthor(s): Zhihui Deng, John DavisAbstractThere is evidence of disrupted cerebral blood flow in patients with a skull defect due to decompressive craniectomy though the pathophysiologic mechanism is yet to be established. Here we report on a patient who suffered one episode of transient ischemic attack (TIA) when developing early stage sinking skin flap syndrome (SSFS) post decompressive craniectomy due to a severe traumatic brain injury. This case report of TIA as a clinical presentation of SSFS indicating a potentially increased risk ...

CONCLUSIONS: Although a big step forward that will benefit many patients has been taken with recent trials, many questions remain unanswered. Pending results from further studies, decision-making regarding management of patients with PFO-associated ischaemic stroke should be based on a close coordination between neurologists/stroke specialists and cardiologists.

ConclusionBaseline cut off thrombus appearance predicts a  higher number of thrombectomy maneuvers. In day to day practice this may prepare the neurointerventionalist for a more challenging endovascular procedure ahead. Stroke etiology, clinical outcomes and thrombus-specific characteristics did not show any associations with the thrombus appearance.

Conclusions: These findings suggest that low UA and low BMI have a joint effect on poor outcomes in IS patients. Across BMI categories, uric acid is differentially associated with functional outcome after stroke. This effect of low UA in the low BMI groups may be one of the mechanisms underlying the obesity-stroke paradox of the outcome in IS patients.

Today's open access paper is a review of potential approaches that might be used as a basis for therapies to restore a more youthful level of neurogenesis in the aging mammalian brain. Neurogenesis is the process by which new neurons are created by neural stem cell populations and then integrated into neural networks. In adults, neurogenesis is essential to memory, learning, and the limited degree of regeneration that the brain is capable of enacting. Unfortunately, the supply of new neurons declines with age as the underlying stem cells become ever less active. Beyond making the aging brain more resilient, methods of incr...
