The ability to successfully transplant cells and organs from a donor into an immunologically disparate recipient is one of the greatest treatment advances in the history of medicine. Nevertheless, acute and chronic rejection, graft versus host disease, and the inability to identify suitable donors continue to be challenges and limit broader application of cell and organ transplantation to the many patients that could benefit. Immunosuppression before and after allogeneic transplant has been found to dramatically im [...]

Background: Mindfulness-Based Stress Reduction (MBSR) is an evidence-based intervention developed to teach mindfulness meditation to a wide range of patients. Although the efficacy of MBSR has been established for a variety of medical and psychiatric conditions, measured outcomes rarely include physical symptoms related to anxiety, depression, and/or stress. The current study presents a secondary analysis of data obtained from patients seeking MBSR for symptoms of anxiety, depression, and/or other stress-related co [...]

Background: One of the goals of clinical islet transplantation is to achieve a single-donor transplant that is dependent on obtaining enough quality β cell mass from one donor pancreas. Human islets are routinely cultured prior to transplantation, and pro-survival factors such as GLP-1 analogues have been reported to maintain β cell mass and survival. Interestingly, human islets may secrete GLP-1 and they also express the enzyme DPP4 that proteolytically cleaves GLP-1 into an inactive form. The aim of [...]

Heart transplant remains the gold standard therapy for patients with end stage heart disease and offers improved survival and quality of life. Significant progress has been achieved in improving one-year mortality after heart transplantation. Nonetheless, long-term graft survival has not changed significantly over the past few decades. Long term survival of heart transplant recipients is limited by chronic rejection, cardiac allograft vasculopathy (CAV), and malignancy. CAV is a major contributor for graft failure [...]

Infertility affects millions globally, with 10-15% of couples experiencing unexplained cases. Despite advancements in medicine, the cause remains unknown, causing emotional distress. Recent research suggests a genetic basis for this issue. This review aims to provide a better understanding of the underlying genetic factors contributing to unexplained infertility and potentially identify genetic markers that could aid in the diagnosis and treatment of this condition. A literature review was conducted to understand t [...]

Homeopathy is often attacked with claims of not being evidence-based or for the implausible nature of its major principles of dilution/potentization and/or the similars (“similia similibus curentur”). However, these statements have already been falsified on the experimental ground, besides being incorrect on an epistemological level. Here we provide an updated appraisal of the scientific approach to the principle of Similars and homeopathy, focusing on laboratory models. After a brief historical introdu [...]

We review the use of numerical and computational models to explore deep brain stimulation for Parkinson’s disease (DBS PD). It is a review for the modeler and those interested in PD DBS modelling methods and their value. The main model categories of active fiber, mean field, driving force, and volume of tissue activated are described as well as many modelling techniques. We give the basic requirements for a DBS PD model and current theories of DBS mechanism of action, PD etiology, and movement selection. The emphas [...]

Bone marrow transplants remain an import source of hematopoietic stem cells for patients suffering from specific diseases like aplastic anemia, for pediatric patients with malignant and non-malignant blood cell disorders, and for situations in which graft-versus-host disease (GvHD) is a concern. Identifying the optimal donor to achieve a 3-5 x 108/kg of recipient weight TNC yield may be challenging. In an analysis of 687 consecutive donors, donor and procedure characteristics were related to TNC/kg of recipient wei [...]

Flavonoids are phytochemicals (polyphenols) of plant origin. They can trap free oxygen radicals generated by mitochondria and other electronic transport chains, thereby inhibiting inflammatory and carcinogenic changes in vivo and in vitro. Why the body requires these compounds for the well-being of the organism and the maintenance of human health remains unclear. However, a deficit of flavonoids could lead to molecular malfunctions in cells, organelles, and macromolecules. This manuscript describes the occurrence a [...]

Background: Dementia is a progressive and debilitating condition that affects millions of patients in the United States with an enormous impact on healthcare costs, caregivers, and society. Patients with dementia often experience dementia-related neuropsychiatric disturbances, commonly known as Behavioral and Psychological Symptoms of Dementia (BPSD) and more recently Neuropsychiatric symptoms (NPS) in dementia. These symptoms include verbal and physical agitation, aggression, disinhibition, affect lability, apathy [...]
