Background -Heart failure (HF) leads to mitochondrial dysfunction and metabolic abnormalities of the failing myocardium coupled with an energy-depleted state and cardiac remodeling. The mitochondrial deacetylase sirtuin 3 (SIRT3) plays a pivotal role in the maintenance of mitochondrial function through regulating the mitochondrial acetylome. Interestingly, unique cardiac and systemic miRNAs have been shown to play an important role in cardiac remodeling by modulating key signaling elements in the myocardium...

BACKGROUND: Preparations from roots of Salvia miltiorrhiza, a herb widely used in traditional Chinese medicine, have been reported to induce a series of central effects, including sedation. In the wake of this ethnopharmacological information, the present study was designed to assess the anxiolytic potential of an extract of S.miltiorrhiza roots. METHODS: To this end, rats were acutely treated with S.miltiorrhiza extract (0, 50, and 100 mg/kg; i.g.) and exposed to the Elevated Plus Maze (EPM) test...

BACKGROUND: Chronic benign neutropenia of infancy includes primary autoimmune neutropenia (pAIN) and chronic idiopathic neutropenia (CIN). A diagnosis of CIN is supported by the absence of free and/or cell-bound neutrophil autoantibodies, which can be detected by flow cytometry with the indirect-granulocyte immunofluorescence test (I-GIFT) and direct-granulocyte immunofluorescence test (D-GIFT), respectively. Conclusive evidence is lacking on the diagnostic value of the D-GIFT, whose performance requires specific laboratory expertise, may be logistically difficult, and hampered by very low neutrophil count in patient samples...

Smoking-cessation therapy reduces the risk of smoking-related diseases, but is successful only in a fraction of smokers. There is growing evidence that genetic variations in nicotinic acetylcholine receptor (nAChR) subunits influence the risk of nicotine dependence and the ability to quit smoking. To investigate the role of polymorphisms in nAChR genes on smoking quantity and the outcome of smoking-cessation therapies, we carried out an association study on 337 smokers who underwent pharmacotherapy with varenicline, bupropion, nicotine replacement therapy (NRT) alone, or NRT plus bupropion...

OBJECTIVES: This study sought to determine if the presence of implantable cardioverter-defibrillators (ICD) provided a mortality benefit during continuous-flow left ventricular assist device (LVAD) support. BACKGROUND: An ICD decreases mortality in selected patients with advanced heart failure and have been associated with reduced mortality in patients with pulsatile LVAD. However, it is unclear whether that benefit extends to patients with a contemporary continuous-flow LVAD...

BACKGROUND: Gastrointestinal (GI) bleeding is one of the most common complications after continuous-flow left ventricular assist device implantation. More than one third of patients with incident bleed go on to develop recurrent GI bleeding. Octreotide, a somatostatin analog, is proposed to reduce the risk of recurrent GI bleeding in this population. METHODS AND RESULTS: This multicenter, retrospective analysis evaluated 51 continuous-flow left ventricular assist device patients who received secondary prophylaxis with octreotide after their index GI bleed from 2009 to 2015...

OBJECTIVES: Orthotopic heart transplantation (OHT) is limited by a chronic shortage of donors. With the evolution of technology, more patients have been bridged to transplant (BTT) through various pathways using various types of mechanical circulatory support. We compared short- and long-term outcomes among these various strategies of BTT. METHODS: We retrospectively reviewed 410 patients who had OHT between January 2009 and April 2015. Patients were divided into 4 groups according to BTT status: primary OHT without bridging (Group A, n  = 246); bridge with implantable continuous-flow left ventricular assist device (CF-LVAD) (Group B, n  = 130); bridge with short-term mechanical circulatory support (Group C, n  = 16) and bridge with multiple mechanical circulatory supports, including short-term mechanical circulatory support and CF-LVAD (Group D, n  = 18)...

Obesity phenotype can be manifested as an isolated trait or accompanied by multisystem disorders as part of a syndromic picture. In both situations, same molecular pathways may be involved to different degrees. This evidence is stronger in syndromic obesity, in which phenotypes of different syndromes may overlap. In these cases, genetic testing can unequivocally provide a final diagnosis. Here we describe a patient who met the diagnostic criteria for Alström syndrome only during adolescence. Genetic testing was requested at 25 years of age for a final confirmation of the diagnosis...
