Several low oxidation state aluminum-containing cluster anions, LAlH(-) and LAln(-) (n = 2-4, L = N[Si(Me)3]2), were produced via reactions between aluminum hydride cluster anions, AlxHy(-), and hexamethyldisilazane (HMDS). These clusters were characterized by mass spectrometry, anion photoelectron spectroscopy, and density functional theory (DFT) based calculations. Agreement between the experimental and theoretical vertical detachment energies (VDEs) and adiabatic detachment energies (ADEs) validated the computed geometrical structures...

BACKGROUND: Bioresorbable coronary stents have been introduced into clinical practice to improve the outcomes of patients treated with percutaneous coronary intervention. The everolimus-eluting bioresorbable vascular scaffold (BVS) is the most studied of these stent platforms; however, recent trials comparing BVS with everolimus-eluting metallic stents (EES) raised concerns about BVS safety. We aimed to assess the efficacy and safety of BVS versus EES in patients undergoing percutaneous coronary intervention...

Idiopathic dilated cardiomyopathy (IDCM) is a frequent cause of heart transplantation. Potentially valuable blood markers are being sought, and low-density lipoprotein receptor-related protein 1 (LRP1) has been linked to the underlying molecular basis of the disease. This study compared circulating levels of soluble LRP1 (sLRP1) in IDCM patients and healthy controls and elucidated whether sLRP1 is exported out of the myocardium through extracellular vesicles (EVs) to gain a better understanding of the pathogenesis of the disease...

BACKGROUND: We hypothesized that patients undergoing surgery for colorectal cancer (CRC) with COPD as a comorbidity would consume more resources and have worse in-hospital outcomes than similar patients without COPD. Therefore, we compared different aspects of the care process and short-term outcomes in patients undergoing surgery for CRC, with and without COPD. METHODS: This was a prospective study and it included patients from 22 hospitals located in Spain - 472 patients with COPD and 2,276 patients without COPD undergoing surgery for CRC...

Mycotoxins can contaminate various food commodities, including cereals. Moreover, mycotoxins of different classes can co-contaminate food, increasing human health risk. Several analytical methods have been published in the literature dealing with mycotoxins determination in cereals. Nevertheless, in the present work, the aim was to propose an easy and effective system for the extraction of six of the main mycotoxins from corn meal and durum wheat flour, i.e., the main four aflatoxins, ochratoxin A, and the mycoestrogen zearalenone...

Currently, there is no uniform classification scheme available for reporting of salivary gland fine-needle aspiration (FNA) specimens. Recently, an International group of pathologists has recommended a tiered classification scheme for reporting of salivary gland FNA results known as the "Milan System for Reporting Salivary Gland Cytopathology (MSRSGC)." We performed a comprehensive review of the published literature on FNA of salivary gland lesions by employing the diagnostic categories of the MSRSGC to evaluate their reliability in the management of salivary gland lesions...

Despite all the efforts made over years to study the cancer expression and the metastasis event, there is not a clear understanding of its origins and effective treatment. Therefore, more specialized and rapid techniques are required for studying cell behaviour under different drug-based treatments. Here we present a quantum dot signalling-based cell assay carried out in a segmental microfluidic device that allows studying the effect of anti-cancer drugs in cultured cell lines by monitoring phosphatidylserine translocation that occurs in early apoptosis...

Temporal patterns, fluxes and inventories of polychlorinated biphenyls (PCBs) were assessed in nine sediment cores collected from selected areas of Admiralty Bay off the Antarctic Peninsula. Concentrations of total PCBs were low, but slightly higher in comparison to low-impacted, remote environments in the world, ranging from below the detection limit to 11.9ngg(-1) in dry weight. PCB concentrations and inventories suggest a possible minor influence related to the nearby logistic activities, especially in the sediment core collected close to the Ferraz Station...

BACKGROUND: Currently, various techniques are used to overcome postoperative pain after total knee arthroplasty. A local analgesic infiltration with periarticular multimodal drug injection (PMDI) is favorable because of its simplicity, safety, and efficacy. The present study compared the efficacy of a PMDI at the anterior vs posterior compartments. METHODS: Forty-six patients were randomized to receive the PMDI at either the anterior or posterior compartment, with the contralateral knee receiving the PMDI at the opposite compartment...

Cardiac cells are subjected to mechanical and electrical forces, which regulate gene expression and cellular function. Therefore, in vitro electromechanical stimuli could benefit further integration of therapeutic cells into the myocardium. Our goals were (a) to study the viability of a tissue-engineered construct with cardiac adipose tissue-derived progenitor cells (cardiac ATDPCs) and (b) to examine the effect of electromechanically stimulated cardiac ATDPCs within a myocardial infarction (MI) model in mice for the first time...

AIMS: Microvascular obstruction (MVO) is associated with a worse prognosis in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). However, data about incidence, clinical outcome and correlates of MVO in latecomers after STEMI are still lacking. METHODS: We prospectively enrolled consecutive patients that were latecomers after STEMI (symptoms onset >12h) undergoing PCI. We performed an angiographic analysis to assess the occurrence of MVO [defined as TIMI flow grade ≤2 or 3 with a myocardial blush grade <2]...

CRISPR is a newly discovered prokaryotic immune system. Bacteria and archaea with this system incorporate genetic material from invading viruses into their genomes, providing protection against future infection by similar viruses. The condition for coexistence of prokaryots and viruses is an interesting problem in evolutionary biology. In this work, we show an intriguing phase diagram of the virus extinction probability, which is more complex than that of the classical predator-prey model. As the CRISPR incorporates genetic material, viruses are under pressure to evolve to escape recognition by CRISPR...

Cardiac tissue engineering, which combines cells and biomaterials, is promising for limiting the sequelae of myocardial infarction (MI). We assessed myocardial function and scar evolution after implanting an engineered bioactive impedance graft (EBIG) in a swine MI model. The EBIG comprises a scaffold of decellularized human pericardium, green fluorescent protein-labeled porcine adipose tissue-derived progenitor cells (pATPCs), and a customized-design electrical impedance spectroscopy (EIS) monitoring system...
