The cutis laxa syndromes are multisystem disorders that share loose redundant inelastic and wrinkled skin as a common hallmark clinical feature. The underlying molecular defects are heterogeneous and 13 different genes have been involved until now, all of them being implicated in elastic fiber assembly. We provide here molecular and clinical characterization of three unrelated patients with a very rare phenotype associating cutis laxa, facial dysmorphism, severe growth retardation, hyperostotic skeletal dysplasia, and intellectual disability...

BACKGROUND: Current retrospective evidence suggests similar clinical and superior hemodynamic outcomes of the Sorin Freedom Solo stentless aortic valve (SFS) (LivaNova PLC, London, UK) compared to the Carpentier Edwards Perimount stented aortic valve (CEP) (Edwards Lifesciences Inc., Irvine, California, USA). To date, no reports exist describing case-matched long-term outcomes and analysis for treatment of native valve endocarditis (NVE). METHODS: From 2004 through 2014, 77 consecutive patients (study group, 59...

BACKGROUND: Mitral regurgitation is a heterogeneous disease. Determining which patients derive optimal outcomes from transcatheter edge-to-edge mitral valve repair (TMVR) remains challenging. We sought to determine whether baseline mitral valve anatomic characteristics are predictive of left atrial pressure (LAP) changes during TMVR with MitraClip. METHODS AND RESULTS: Consecutive patients with severe mitral regurgitation undergoing TMVR (n=112) underwent continuous intraprocedural LAP monitoring and retrospective echocardiographic analysis for specific mitral anatomic characteristics...

Atom-economic and regioselective Csp3-Csp3 bond formation has been achieved by rapid C-H alkylation of unprotected secondary arylamines with unactivated alkenes. The combination of Ta(CH2SiMe3)3Cl2, and a ureate N,O-chelating ligand salt gives an in situ prepared catalytic system that can realize high yields of β-alkylated aniline derivatives using either terminal or internal alkene substrates. These new catalyst systems realize C-H alkylation in as little as one hour and for the first time a 1:1 stoichiometry of alkene and amine substrates results in high yielding syntheses of isolated amine products by simple filtration and concentration...

The long-chain fatty acid receptor FFAR1 is highly expressed in pancreatic β-cells. Synthetic FFAR1 agonists can be used as antidiabetic drugs to promote glucose-stimulated insulin secretion (GSIS). However, the physiological role of FFAR1 in β-cells remains poorly understood. Here we show that 20-HETE activates FFAR1 and promotes GSIS via FFAR1 with higher potency and efficacy than dietary fatty acids such as palmitic, linoleic, and α-linolenic acid. Murine and human β-cells produce 20-HETE, and the ω-hydroxylase-mediated formation and release of 20-HETE is strongly stimulated by glucose...

This work presents kinetic modeling efforts to evaluate the anti-knock tendency of several substituted phenols if used as gasoline additives. They are p-cresol, m-cresol, o-cresol, 2,4-xylenol, 2-ethylphenol, and guaiacol. A detailed kinetic model was constructed to predict the ignition of blends of the phenols in n-butane with the help of reaction mechanism generator (RMG), an open-source software package. The resulting model, which has 1465 species and 27 428 reactions, was validated against literature n-butane ignition data in the low-to-intermediate temperature range...

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) emerged as a new alternative method in minimally invasive techniques. Although a very small number of studies have compared the physiologic response in NOTES to laparoscopy, the results remain controversial. AIM: This experimental animal study aims to evaluate the intraoperative cardiovascular and respiratory effects of pure transluminal natural orifice surgery and conventional laparoscopy. MATERIALS AND METHODS: Twenty female pigs (Sus scrofa domesticus) equally divided into two study groups were assigned to either pure natural orifice transluminal endoscopic techniques (Group 1) or conventional laparoscopic surgery (Group 2) and monitored intraoperatively in terms of heart rate (HR), systolic blood pressure (SBP) and O2saturation (SpO2) for 1 h...

Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb. Endovascular procedures are currently preferred for these patients. We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb. The patient had history of left femoral popliteal bypass surgery, femoral thromboendarterectomy and patch angioplasty of the same limb 2 years ago. Doppler sonography and magnetic resonance angiography revealed an occlusion of the left superficial femoral artery (SFA) and popliteal artery and of all three infra-popliteal arteries...

PURPOSE: To test the hypothesis that cumulative exposure to sulphonylurea (SU) or metformin (MET) have different effects on mortality when taken as a replacement or add-on of one for the other. METHODS: All consecutive diabetes patients aged over 20 years were screened at their first diabetes outpatient visit between 2001 and 2008 (n = 79869). Only patients on MET (n = 11374) or SU (n = 18502) monotherapy were retained. All patients were followed up for death until December 31, 2011, but censored at first exposure to anything else besides MET/SU...

BACKGROUND: The process of assessing the decision-making capacity of potential subjects before their inclusion in clinical trials is a legal requirement and a moral obligation, as it is essential for respecting their autonomy. This issue is especially important in psychiatry patients (such as those diagnosed with schizophrenia). The primary purpose of this article was to evaluate the degree of impairment in each dimension of decision-making capacity in schizophrenia patients compared to non-mentally-ill controls, as quantified by the (MacCAT-CR) instrument...

Gaseous microemboli (GME) are a potential complication of cardiopulmonary bypass (CPB). Though it is difficult to prove that GME is the only major cause of neurological deficits, it may increase the chance of post-operative cognitive dysfunction if not removed. The objectives of this research were to compare LivaNova-Sorin Inspire (Inspire) oxygenator with a Medtronic arterial filter to the Medtronic Fusion (Fusion) oxygenator with and without a Medtronic arterial filter based on each system's ability to handle GME...

Accidental river pollution can cause damage to the environment, put at risk the health of people that use the water for domestic purposes, and, not lastly, compromise dependent economic activities (e.g., agriculture). The reduction of the concentration of pollutant on any river following an accidental pollution can be achieved using dilution, by opening for certain duration the bottom gates of the reservoirs placed on the river's tributaries and releasing a significant volume of clean water in the main river...

Morbid obesity is a metabolic disease characterized by an excessive accumulation of adipose tissue (=40%). This disorder is commonly associated with cardiovascular disease, arteriosclerosis, type 2 diabetes, hypothyroidism and some types of cancer. The most common metabolic signals associated with the disease are leptin, ghrelin, with antagonic effects. Our study aimed at highlighting leptin and ghrelin expression levels, as well as establishing correlations between them and clinical-biological parameters in obese patients...
