Bioengineers discover "breakthrough" technique: 3D-printed organs to be available in the next two decades

(Natural News) Additive manufacturing systems have come one step closer to printing out whole, working organs for emergency medical transplants. Researchers reported 3D printing a complete system of blood vessels found on a major organ. Every day, around 20 patients who desperately need an organ transplant die before ever getting one. There are not enough...

CONCLUSIONS: Anesthetic preconditioning is a promising strategy to prevent I-R injury associated with transplantation. Our results suggest that sirtuin 2 is involved in the protective mechanisms of some commonly used anesthetics against I-R damage. PMID: 31726818 [PubMed - as supplied by publisher]

We report an optic atrophy spectrum disorder, including retinal macular dystrophy and kidney insufficiency leading to transplantation, associated with mitochondrial DNA (mtDNA) depletion without accumulation of multiple deletions. By whole-exome sequencing, we identified mutations affecting the mitochondrial single-strand binding protein (SSBP1) in 4 families with dominant and 1 with recessive inheritance. We show that SSBP1 mutations in patient-derived fibroblasts variably affect the amount of SSBP1 protein and alter multimer formation, but not the binding to ssDNA. SSBP1 mutations impaired mtDNA, nucleoids, and 7S-DNA am...

Sustained, indolent immune injury of the vasculature of a heart transplant limits long-term graft and recipient survival. This injury is mitigated by a poorly characterized, maladaptive repair response. Vascular endothelial cells respond to proangiogenic cues in the embryo by differentiation to specialized phenotypes, associated with expression of apelin. In the adult, the role of developmental proangiogenic cues in repair of the established vasculature is largely unknown. We found that human and minor histocompatibility–mismatched donor mouse heart allografts with alloimmune-mediated vasculopathy upregulated express...

Abstract Live imaging of neutrophils within optically transparent larval zebrafish has proved a powerful technique to investigate how specific gene products control neutrophil function. To resolve whether a gene contributes to neutrophil function in a cell-autonomous manner necessitates a way to examine gene-deficient neutrophils in an otherwise wild type background. To this end, here we describe methods to harvest fluorescent neutrophils from larval donor zebrafish and transplant them into age-matched recipients. We show that transplanted neutrophils can survive in recipient larvae for at least 3 days provid...

Authors: Ghemame M, Charpentier P, Mouriaux F Abstract Developments in corneal topography allow for increasingly precise, detailed analysis of the corneal surface. This test is becoming indispensable in the treatment of complex corneas: keratoconus, corneal transplants, orthokeratology, etc. In refractive surgery, the combined analysis of the anterior and posterior cornea has permitted better screening for forme fruste keratoconus at risk for post-LASIK ectasia. Topography also assists in the calculation of premium intraocular lenses. Topography is an indispensable test for analyzing and following corneal disease. ...

ConclusionsAn improvement in efficacy could not be observed after modified DHAP regimen; however, manageable toxicity and reduced renal complications suggest further investigation. The study, however, also underlines the need for new concepts in the management of advanced and high-risk lymphomas.
