Trimethylation of histone H3 at lysine 4 (H3K4me3) is a chromatin modification known to mark the transcription start sites of active genes. Here, we show that H3K4me3 domains that spread more broadly over genes in a given cell type preferentially mark genes that are essential for the identity and function of that cell type. Using the broadest H3K4me3(More)
Chromatin modifiers regulate lifespan in several organisms, raising the question of whether changes in chromatin states in the parental generation could be incompletely reprogrammed in the next generation and thereby affect the lifespan of descendants. The histone H3 lysine 4 trimethylation (H3K4me3) complex, composed of ASH-2, WDR-5 and the histone(More)
BACKGROUND & AIMS Fractionated plasma separation and adsorption (FPSA) is an extracorporeal procedure that supports liver function by removing endogenous toxins that cause complications from acute-on-chronic liver failure (AOCLF). We performed a randomized trial to investigate survival of patients with AOCLF treated with FPSA. METHODS Patients with AOCLF(More)
BACKGROUND Recently we have devised and tested a biofeedback system for controlling blood volume (BV) changes during hemodialysis (HD) along an ideal trajectory (blood volume tracking, BVT), continuously modifying the weight loss rate and dialysate conductivity. This multicenter, prospective, randomized, crossover study aimed to clarify whether BVT(More)
Dialysis induced hypovolemia plays an important role in triggering intradialytic hypotension. The authors developed an automatic system (BVAC) with feedback changes in the ultrafiltration rate (UFR) and dialysate conductivity (DC) to match blood volume (BV) intradialytic profiles with the desired trajectories. The system consists of three subunits: (1) an(More)
Hemodialysis (HD)-induced hypotension may be precipitated by severe hypovolemia. To avoid the appearance of destabilizing hypovolemias, we have developed a biofeedback control system for intradialytic blood volume (BV)-changes modeling. The system, incorporated in a dialysis machine, is based on a multivariable closed-loop control with a dependent output(More)
BACKGROUND In the USA, the increase in the prevalence of obesity in the general population has been accompanied by a marked increase in the prevalence and incidence of obesity in the dialysis population. However, secular trends of body mass index (BMI) have not been investigated in European renal registries. METHODS We investigated the secular trend of(More)
Metabolism is influenced by age, food intake, and conditions such as diabetes and obesity. How do physiological or pathological metabolic changes influence stem cells, which are crucial for tissue homeostasis? This Commentary reviews recent evidence that stem cells have different metabolic demands than differentiated cells, and that the molecular mechanisms(More)

BACKGROUND Adiponectin has antisteatosis-anti-inflammatory properties and its circulating levels are reduced in nonalcoholic steatohepatitis (NASH). METHODS To assess the role of adiponectin in NASH, we measured expression of adiponectin gene (APM1) and receptors (AdipoR1/AdipoR2) in liver and subcutaneous and visceral fat in subjects with biopsy-proven(More)
