Objective: To investigate exogenous gene expressing ability of adipose tissue-derived stromal cell (ADSCs) and cell distribution after they were transplanted into brains, and to get the genetically modified cells for autografting.
Methods: ADSCs were transfected by Ad5beta gal adenovirus containing a report gene, LacZ gene, then they were transplanted into the adult brain of rats, or ADSCs labeled by Hoechst33258 were transplanted into the adult brain of rats to investigate the migration and distribution of cells.
Results: ADSCs showed a good expression of LacZ with X-gal staining after transfecting and transplantation into adult brains, and they could incorporate into the host brain tissues and no disruption was observed. These cells showed good compatibility with the host brains.
Conclusion: The results indicate that ADSCs could incorporate into host brains and express exogenous gene steadily when they were transplanted into adult brain tissues, no overproliferation and gliosis were identified, and ADSCs may be used as a therapeutic gene delivery vehicle in treating CNS disorders in humans.

Because of the lengthening of their life-expectancy, more people with cystic fibrosis (CF) now pursue parenthood. To explore the experience of parenting while having CF, 18 French parents with CF were interviewed (including 12 mothers and 9 participants with a lung transplant). A thematic analysis of the interview transcripts was conducted.

Background: Cardiomyopathy is a disease that affects the myocardium and can be classified as dilated, restrictive, or hypertrophic cardiomyopathy. Among the subtypes, restrictive cardiomyopathy is characterized by restriction of ventricular filling and its uncommon cause is a disease due to mutation on Filamin C (FLNC) gene. Filamin C is an actin-binding protein encoded by FLNC gene and participates in sarcomere stability maintenance, which is expressed on the striated muscle.

Background: Proteinuria is associated with worse allograft outcomes in kidney transplant recipients (KTRs) and treatment strategies are limited. We examined the outcomes of calcineurin inhibitor (CNI) to belatacept conversion in proteinuric KTRs.
Methods: In a pilot phase II single-arm multicenter prospective trial, we recruited adult KTRs >6 months post-kidney transplantation with an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.
Resilience to stressors has emerged as a major gerontological concept aiming to promote more positive outcomes for older adults. Achieving this aim relies on determining mechanisms underlying capacity to respond resiliently. This paper seeks proof of principle for the hypothesis that physical aspects of said capacity are rooted in the fitness of one's physiology governing stress response, conceptualized as a dynamical system.

Introduction: Kidney failure is a life-limiting condition that profoundly impacts an individual's quality of life. The significant medication burden on patients required to manage the comorbidities and complications of kidney failure can have implications for patient-reported and clinical outcomes.
Methods: This work systematically reviewed methods used to assess medication regimen complexity amongst adults with kidney failure, the associated patient-reported and clinical outcomes, and the effectiveness of interventions to address regimen complexity.
