γδ T cells has been shown to exhibit profound antitumor effects in a broad range of tumor entities, including OS. However, resistance to γδ T cells is a serious problem in the management of OS. This study investigates the impact of celastrol on the expression of death receptors 4/5 (DR4/5) on OS cell lines (HOS, U2OS) and cancer cell lysis by γδ T cells. The results showed that celastrol increased transcription of DR4/5 in HOS and U2OS, leading to increased cell surface, and total DR4/5 protein expression...

Hemolytic uremic syndrome (HUS) is a thrombotic microangiopathy defined by thrombocytopenia, non-immune microangiopathic hemolytic anemia and acute renal failure. HUS is typically classified into two primary types: 1) HUS due to infections, often associated with diarrhea (D+HUS, Shiga toxin-producing Escherichia Coli-HUS), with the rare exception of HUS due to a severe disseminated infection caused by Streptococcus; 2) HUS related to complement, such HUS is also known as "atypical HUS" and is not diarrhea associated (D-HUS, aHUS); but recent studies have shown other forms of HUS, that can occur in the course of systemic diseases or physiopathological conditions such as pregnancy, after transplantation or after drug assumption...

Plant viruses are mostly transmitted by sucking insects via their piercing behaviors, which may differ due to host plant species and their developmental stages. We characterized the transmission of a fijivirus, southern rice black-streaked dwarf virus (SRBSDV), by the planthopper vector Sogatella furcifera Horváth (Hemiptera: Delphacidae), between rice and corn plants of varying developmental stages. SRBSDV was transmitted from infected rice to uninfected corn plants as efficiently as its transmission between rice plants, while was acquired by S...

OBJECTIVES: Individuals older than 60 years represent a large proportion of the organs available for orthotopic liver transplant. However, the use of organs from older donors remains controversial. We hypothesized that the use of older donors would not affect patient and graft survival due to significant improvements in donor-recipient management. MATERIALS AND METHODS: We conducted a retrospective cohort analysis using the United Network for Organ Sharing database from February 2002 through December 2012, including non-HCV-infected adults (18 and older) who underwent primary orthotopic liver transplant...

BACKGROUND: Uganda implemented a national ART scale-up program at public and private health facilities between 2004 and 2009. Little is known about how and why some health facilities have sustained ART programs and why others have not sustained these interventions. The objective of the study was to identify facilitators and barriers to the long-term sustainability of ART programs at six health facilities in Uganda which received donor support to commence ART between 2004 and 2009. METHODS: A case-study approach was adopted...

BACKGROUND: Most pediatric liver transplantation (LT) centers administer long courses of prophylaxis against Cytomegalovirus (CMV) without evidence of benefit and with significant drug exposure and costs. We aimed at evaluating overall outcomes, direct and putative indirect effects of CMV, possible impact of viremia and risk factors for CMV infection in pediatric LT recipients managed with ganciclovir-based preemptive therapy (PET). METHODS: The records of all the children who underwent LT between 2008 and 2014 were retrospectively analyzed...

PURPOSE: The aims of this study were to analyze the characteristics of patients with acute liver failure (ALF) in our center and evaluate the prognostic value of the Pediatric End-Stage Liver Disease (PELD) score calculated at admission. PATIENTS AND METHODS: A retrospective analysis of patients with ALF younger than 15 years between 2005 and 2013 was performed. Information collected included age, sex, etiology of ALF, laboratory tests, PELD score, stage of encephalopathy, and need for liver support devices such as MARS and/or liver transplant (LT) and survival...

Blood and Marrow Transplant Clinical Trials Network (BMT CTN) Protocol 0902 evaluated whether exercise and stress management training prior to hematopoietic cell transplantation (HCT) improved physical and mental functioning after HCT. Neither overall survival nor other patient-reported transplant outcomes were improved by the training intervention. In some animal studies of HCT, moderate intensity exercise for 8 weeks before HCT has been associated with positive effects on hematopoietic progenitors resulting in improved donor engraftment and improved survival...

BACKGROUND: The development of metabolic syndrome (MS) after liver transplantation (LT) is a major source of mortality derived from cardiovascular events. The aim of the present study was to determine the prevalence and risk factors of MS after LT. METHODS: One-hundred seventy-four consecutive LT patients from January 2004 to June 2010 surviving longer than 1 year after LT were included. Median follow-up after LT was 48 months. Independent predictors of MS were obtained by means of multivariate logistic regression...

It is well known that the quality of organs retrieved from brain-dead donors (DBDs) is better than those retrieved from circulatory death donors. However, in situations of organ retrieval from marginal DBDs, who are unstable despite intensive care, transplantation outcomes are not good. Organ ischemia is the most important determining factor in decreased organ quality in circulatory death donors and in some DBDs. Extracorporeal membrane oxygenation (ECMO) for management of DBDs can be an emergency countermeasure...

Establishing an organization to promote organ donation and a good organ procurement team assure quality and improve performance on organ donation rates. Brazil's organ procurement structure is based on 2 models disseminated worldwide: the "Spanish model," based on in-house coordinators, and the "American organ procurement organization (OPO) model," with extra-hospital coordinators. In 2006, Brazil's Federal Government had formally introduced the in-house coordination model for every hospital equipped with a mechanical ventilator bed...

The prognosis for disease relapse after first hematopoietic cell transplantation (HCT1) is poor. Here, we present a retrospective multicenter study to evaluate the clinical outcome and the prognostic factors for second hematopoietic cell transplantation (HCT2). The cohort in this study comprised 60 patients diagnosed with acute leukemia, who underwent HCT2 due to hematological relapse after HCT1. The overall survival (OS) at two years, non-relapse mortality (NRM), and relapse mortality (RM) were 30.3%, 40.9%, and 28...

BACKGROUND: Understanding the effect of delayed processing of whole blood on plasma ferritin will inform the feasibility of both routine ferritin testing in donors and clinical research study design. STUDY DESIGN AND METHODS: Whole blood tubes drawn from 16 donors were held at 4°C and centrifuged at 24-hour intervals to assess plasma ferritin concentration up to 5 days after draw. Intraindividual variation over time was measured in 21 healthy donors in blood samples collected weekly for 4 weeks and then at 12 weeks...

In New Zealand, embryo donation (ED) is "open," allowing offspring to access genetic information. Donors and recipients meet prior to donation. Drawing on interviews with 15 recipients, 22 donors, and nine counselors, this article discusses how ED may be constructed as a form of gifting. This discourse may evoke expectations that recipients will express gratitude for the gift, including through honoring contact agreements. Donation becomes a relational practice of obligations and counter-obligations. However, the gift discourse may not adequately capture the emotional sacrifice experienced by donors...

INTRODUCTION: Hospital autopsies, vanishing worldwide, need to be requested by clinicians and consented to by next-of-kin. The aim of this prospective observational study was to examine how often and why clinicians do not request an autopsy, and for what reasons next-of-kin allow, or refuse it. METHODS: Clinicians at the Erasmus University Medical Centre were asked to complete a questionnaire when an adult patient had died. Questionnaires on 1000 consecutive naturally deceased adults were collected...

Successful renal transplantation is the optimal treatment for chronic kidney failure, but this was not always so for children. Beginning with the first kidney transplants in the 1950s, children experienced poorer patient and graft survival rates than adult patients. But over the last 6 decades, an improved understanding of the immune system which has steered pediatric multi-center clinical / pharmacokinetic and mechanistic studies that have sculpted our immunosuppression with markedly better patient and graft survivals...

More than 60% of phosphorus (P) taken up by rice (Oryza spp.) is accumulated in the grains at harvest and hence exported from fields, leading to a continuous removal of P. If P removed from fields is not replaced by P inputs then soil P stocks decline, with consequences for subsequent crops. Breeding rice genotypes with a low concentration of P in the grains could be a strategy to reduce maintenance fertilizer needs and slow soil P depletion in low input systems. This study aimed to assess variation in grain P concentrations among rice genotypes across diverse environments and evaluate the implications for field P balances at various grain yield levels...
