Thymus and aging: potential of gene therapy for restoration of endocrine thymic function in thymus-deficient animal models.

abstract：BACKGROUND:Falls are a significant problem for older adults. Individuals who have sustained a fall come to the attention of health care providers and are at risk of further falls. To promote the highest quality of care and reduce variation in care, a practice guideline is needed. Summarization of evidence regarding fal...
