Two ruthenium(II) complexes Ru1 and Ru2 bearing as a one ligand 2,2'-bipyridine substituted by a semicarbazone 2-formylopyridine moiety (bpySC: 5-(4-{4'-methyl-[2,2'-bipyridine]-4-yl}but-1-yn-1-yl)pyridine-2-carbaldehyde semicarbazone) and as the others 2,2'-bipyridine (bpy) and 4,7-diphenyl-1,10-phenanthroline (dip), respectively, as auxiliary ligands have been prepared. Their biological activity has been studied on murine colon carcinoma (CT26) and human lung adenocarcinoma (A549) cell lines. The anti-proliferative activity was dependent on the presence of bpy or dip in the complex, with one order of magnitude higher cytotoxicity for Ru2 (dip ligands)...

Using a large panel of theoretical approaches, i.e., CC2, CCSD, CCSDR(3), CC3, ADC(2), ADC(3), CASPT2, TD-DFT and BSE/evGW, the two latter combined with different exchange-correlation functionals, we investigated the lowest singlet transition in twenty-three n-pi* compounds based on the nitroso, thiocarbonyl, carbonyl and diazo chromophores. First, for sixteen small derivatives we compare the transition energies provided by the different wavefunction approaches to define theoretical best estimates. For this set, it surprisingly turned out that ADC(2) offers a better match with CC3 than ADC(3)...

Importance: Annually in the United States, at least 3.5 million people seek medical attention for traumatic brain injury (TBI). The development of therapies for TBI is limited by the absence of diagnostic and prognostic biomarkers. Microtubule-associated protein tau is an axonal phosphoprotein. To date, the presence of the hypophosphorylated tau protein (P-tau) in plasma from patients with acute TBI and chronic TBI has not been investigated. Objective: To examine the associations between plasma P-tau and total-tau (T-tau) levels and injury presence, severity, type of pathoanatomic lesion (neuroimaging), and patient outcomes in acute and chronic TBI...

OBJECTIVES: To assess whether reversing the veno-arterial extracorporeal membrane oxygenation blood flow (thereby creating a controlled arterio-venous shunt) can be used to wean children off extracorporeal membrane oxygenation. The standard practice for weaning patients off VA extracorporeal membrane oxygenation is to gradually reduce the blood flows delivered through the extracorporeal membrane oxygenation pump to a minimum level followed by either insertion of an "arterio-venous bridge" and clamping of the blood flow to the patient or direct decannulation...

AIM: We aimed to investigate the safety and efficacy of dienogest (DNG), a progestational 19-norsteroid, administered for 52 weeks in patients with symptomatic adenomyosis. METHODS: A total of 130 patients with adenomyosis received 2 mg of DNG orally each day for 52 weeks. In cases of complicated anemia, patients were treated for anemia prior to receiving the medication. Adverse events and adverse drug reactions were evaluated. The patients' pain symptoms (dysmenorrhea and pelvic pain from adenomyosis) were assessed using a pain-scoring tool...

BACKGROUND: Regulatory agencies have concluded that sodium glucose cotransporter 2 (SGLT2) inhibitors lead to ketoacidosis, but published literature on this point remains controversial. METHODS: We searched the FDA Adverse Event Reporting System (FAERS) for reports of acidosis in patients treated with canagliflozin, dapagliflozin, or empagliflozin (from the date of each drug's FDA approval until May 15, 2015). We compared the number of SGLT2 inhibitor-related reports to reports of acidosis in patients treated with the two most commonly used DPP4 inhibitors: sitagliptin and saxagliptin...

Density Functional Tight Binding (DFTB) models are two to three orders of magnitude faster than ab initio and Density Functional Theory (DFT) methods and therefore are particularly attractive in applications to large molecules and condensed phase systems. To establish the applicability of DFTB models to general chemical reactions, we conduct benchmark calculations for barrier heights and reaction energetics of organic molecules using existing databases and several new ones compiled in this study. Structures for the transition states and stable species have been fully optimized at the DFTB level, making it possible to characterize the reliability of DFTB models in a more thorough fashion compared to conducting single point energy calculations as done in previous benchmark studies...

PURPOSE: Spatially fractionated radiotherapy is a strategy to overcome the main limitation of radiotherapy, i.e., the restrained normal tissue tolerances. A well-known example is Grid Therapy, which is currently performed at some hospitals using megavoltage photon beams delivered by Linacs. Grid Therapy has been successfully used in the management of bulky abdominal tumors with low toxicity. The aim of this work is to evaluate whether an improvement in therapeutic index in Grid Therapy can be obtained by implementing it in a flattening filter-free (FFF) Linac...

Background: Suffering from tinnitus causes mental distress in most patients. Recent findings point toward a diminished activity of the brain's default-mode network (DMN) in subjects with mental disorders including depression or anxiety and also recently in subjects with tinnitus-related distress. We recently developed a therapeutic intervention, namely the Heidelberg Neuro-Music Therapy (HNMT), which shows an effective reduction of tinnitus-related distress following a 1-week short-term treatment. This approach offers the possibility to evaluate the neural changes associated with the improvements in tinnitus distress...

The members of the Management and Therapy Subcommittee undertook an evidence-based review of current dry eye therapies and management options. Management options reviewed in detail included treatments for tear insufficiency and lid abnormalities, as well as anti-inflammatory medications, surgical approaches, dietary modifications, environmental considerations and complementary therapies. Following this extensive review it became clear that many of the treatments available for the management of dry eye disease lack the necessary Level 1 evidence to support their recommendation, often due to a lack of appropriate masking, randomization or controls and in some cases due to issues with selection bias or inadequate sample size...

BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage renal disease. The standard surgery uses the recipient's iliac vessels for vascular anastomosis. Thrombosis and/or stenosis of the iliac vein, which are possible complications of multiple vascular access points for dialysis, can be detected intraoperatively, constituting a surgical challenge. An infrequently reported option is the use of the gonadal vein. OBJECTIVES: This study aims to evaluate the outcomes of venous anastomosis in the gonadal vein in patients with iliac vein thrombosis and/or stenosis submitted to kidney transplantation...

There have been great research advances in epigenetics, RNA splicing, and mRNA processing over recent years. In parallel, there have been many advances in abiotic stress and Abscisic Acid (ABA) signaling. Here we overview studies that have examined stress-induced changes in the epigenome and RNA processing as well as cases where disrupting these processes changes the plant response to abiotic stress. We also highlight some examples where specific connections of stress or ABA signaling to epigenetics or RNA processing have been found...

BACKGROUND: Epithelial to mesenchymal transition (EMT) is considered to be important for cancer invasion and metastasis. Tumour hypoxia, in addition to Transforming Growth Factor-β (TGF-β) and Notch, amongst others, have been suggested to be involved in EMT. We therefore investigated if hypoxia, TGF-β1 and the Notch ligand Jagged-1 alone induced morphological changes with corresponding EMT signatures in different epithelial breast cancer cell lines in vitro. Furthermore, we also studied whether or not TGF-β1, or Jagged-1 in combination with hypoxia added any effect on EMT...

BACKGROUND: The use of porous tantalum for the acetabular component in primary total hip arthroplasty (THA) has demonstrated excellent short-term and midterm results. However, long-term data are scarce. The purpose of this prospective study is to report the long-term clinical and radiologic outcome following use of an uncemented porous tantalum acetabular component in primary THA with a minimum follow-up of 17.5 years, in a previously studied cohort of patients. METHODS: We prospectively followed 128 consecutive primary THAs in 140 patients, between November 1997 and June 1999...

Benchmark adiabatic ionization potentials were obtained with the Feller-Peterson-Dixon (FPD) theoretical method for a collection of 48 atoms and small molecules. In previous studies, the FPD method demonstrated an ability to predict atomization energies (heats of formation) and electron affinities well within a 95% confidence level of ±1 kcal/mol. Large 1-particle expansions involving correlation consistent basis sets (up to aug-cc-pV8Z in many cases and aug-cc-pV9Z for some atoms) were chosen for the valence CCSD(T) starting point calculations...

We extend projection-based embedding techniques to bulk systems to treat point defects in semiconductors and insulators. To avoid non-additive kinetic energy contributions, we construct the density partition using orthogonal subsets of orbitals. We have implemented our approach in the popular Vienna ab initio simulation package software package. We demonstrate its power for defect structures in silicon and polaron formation in titania, two challenging cases for conventional Kohn-Sham density functional theory...

BACKGROUND: Smoking is associated with adverse effects in the perioperative period, including elevated risk of death. The perioperative period provides an opportunity to engage with patients who are smokers to encourage smoking cessation, often referred to as a 'teachable moment'. We developed a smoking intervention model for the pre-admission clinic (PAC) at Western Health, Victoria, Australia. This case series aimed to assess the impact of the smoking intervention model, which is standard of care, on the participant's smoking habits over four time points...

The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence. This licence sets the discharge limits for a range of analytes to protect the environment into which the produced water is discharged. This study reports on the impact of produced water from coal mine activities located within or discharging into high conservation environments, such as National Parks, in the outer region of Sydney, Australia...
