The management of chloramine decay and the prevention of nitrification are some of the critical issues faced by water utilities that use chloramine as a disinfectant. In this study, potential association between high performance size exclusion chromatography (HPSEC) data obtained with multiple wavelength Ultraviolet (UV) detection from two drinking water distribution systems in Australia and nitrification occurrence was investigated. An increase in the absorbance signal of HPSEC profiles with UV detection at λ=230nm between apparent molecular weights of 200 to 1000Da was observed at sampling sites that experienced rapid chloramine decay and nitrification while its absorbance signal at λ=254nm decreased...

A variety of syndromic diseases such as Marfan syndrome, Loeys-Dietz syndrome, and bicuspid aortic valve with aneurysm along with risk factors of smoking and hypertension result in ascending aortic aneurysms and dissections. Historically, a complicated variety of terms have been used to describe a range of histopathologies that are present in resected specimens. As a result, no consistent patterns of histopathology have been reported. We used the recent Society for Cardiovascular Pathology/Association for European Cardiovascular Pathology consensus statement on nomenclature and diagnostic criteria for noninflammatory aortic disease to blindly evaluate 148 surgically resected specimens...

Biofilms, which are complex microbial communities embedded in the protective extracellular polymeric substances (EPS), are difficult to remove in food production facilities. In this study, the use of acidic electrolyzed water (AEW) to remove foodborne pathogen biofilms was evaluated. We used a green fluorescent protein-tagged Escherichia coli for monitoring the efficiency of AEW for removing biofilms, where under the optimal treatment conditions, the fluorescent signal of cells in the biofilm disappeared rapidly and the population of biofilm cells was reduced by more than 67%...

INTRODUCTION: Elevated plasma homocysteine (Hcy) levels have been associated with several tissue injuries including heart and liver fibrosis. In these diseases, hyperhomocysteinemia (Hhcy) plays a major role in modulating the alteration of the balance between matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMPs), leading to the pathological accumulation of extracellular matrix (ECM) proteins. Since the effect of Hhcy on ECM of seminal vesicle was not studied, the aim of our research was to check if Hcy can induce a remodeling within seminal vesicles ECM...

Background: Accumulating evidence suggests that neuroinflammation plays a critical role in early brain injury after subarachnoid hemorrhage (SAH). Pannexin-1 channels, as a member of gap junction proteins located on the plasma membrane, releases ATP, ions, second messengers, neurotransmitters, and molecules up to 1 kD into the extracellular space, when activated. Previous studies identified that the opening of Pannexin-1 channels is essential for cellular migration, apoptosis and especially inflammation, but its effects on inflammatory response in SAH model have not been explored yet...

Stems and leaves of Olea europaea L. (olive) avoid freezing damage by substantial supercooling during the winter season. Physiological changes during acclimation to low temperatures were studied in five olive cultivars. Water relations and hydraulic traits, ice nucleation temperature (INT) and temperatures resulting in 50% damage (LT50) were determined. All cultivars showed a gradual decrease in INT and LT50 from the dry and warm summer to the wet and cold winter in Patagonia, Argentina. During acclimation to low temperatures there was an increase in leaf cell wall rigidity and stomatal conductance (gs), as well as a decrease in leaf apoplastic water content, leaf water potential (Ψ), sap flow and stem hydraulic conductivity (ks)...

Diffusion tensor imaging (DTI) has often been used to examine white matter (WM) tract abnormalities in depressed subjects, but these studies have yielded inconsistent results, probably, due to gender composition or small sample size. In this study, we applied different analysis pipelines to a relatively large sample of individuals with depression to determine whether previous findings in depression can be replicated with these pipelines. We used a "standard" DTI algorithm and maps computed through a free-water (FW) corrected DTI...

Quantitative myelin water imaging (MWI) from signal T2* decay acquired with multiple Gradient-Recalled Echo (mGRE) sequence has been widely used since its first report. A recent study showed that with low resolution data (2mm isotropic voxels), direct application of complex fitting to a three-pool WM model with frequency shift terms could produce more stable parameter estimation for myelin water fraction mapping. MWI maps of higher spatial resolution resulting in more detailed tissue structures and reduced partial volume effects around white matter/gray matter (WM/GM) interface, however, is more desirable...

BACKGROUND: Radiolabeled RGD peptides detect αvβ3 integrin expression associated with angiogenesis and extracellular matrix remodeling after myocardial infarction. We studied whether cardiac positron emission tomography (PET) with [(68)Ga]NODAGA-RGD detects increased αvβ3 integrin expression after induction of flow-limiting coronary stenosis in pigs, and whether αvβ3 integrin is expressed in viable ischemic or injured myocardium. METHODS: We studied 8 Finnish landrace pigs 13 ± 4 days after percutaneous implantation of a bottleneck stent in the proximal left anterior descending coronary artery...

This study investigated the effects young leaves of reed (Phragmites communis) water extract (YLR) on melanogenesis and oxidative stress using B16F10 cells. YLR decreased the intracellular melanin content, protein expression and enzyme activity of tyrosinase in a dose-dependent manner. YLR significantly decreased the gene and protein expression of melanogeneis-related proteins, such as microphthalmia-associated transcription factor (MITF), and tyrosinase-related protein-1 and -2. In addition, YLR up-regulated the melanogenesis inhibitory proteins, extracellular signal-regulated kinase (ERK) and protein kinase B (AKT), while it dose-dependently down-regulated p38 and cAMP response element-binding protein (CREB)...

An electrochemical flow cell equipped with a graphite working electrode (WE) at the bottom was inoculated with Shewanella oneidensis MR-1 expressing an anaerobic fluorescence protein, and biofilm formation on WE were observed over time during current generation at WE potentials of +0.4 and 0 V (vs. standard hydrogen electrodes) under electrolyte-flow conditions. Electrochemical analyses suggest the presence of unique electron-transfer mechanisms in the +0.4 V biofilm. Microscopic analyses revealed that, different from aerobic biofilms, current-generating biofilm (at +0...

McKittrick-Wheelock syndrome is characterized by extracellular volume depletion and severe fluid and electrolyte imbalance caused by secretory tumors of the rectum, usually villous adenomas. Patients usually present signs of dehydration, hyponatremia, hypokalemia, and prerenal azotemia due to the chronic diarrhea, rich in ions and water. Since this is a potencially lethal entity without treatment, and a very unusual condition, we report a clinical case. Treatment consists in surgical resection of the tumor, although endoscopy polypectomy has also been reported...

Dinoseb is a highly toxic pesticide of the dinitrophenol group. Its use has been restricted, but it can still be found in soils and waters in addition to being a component of related pesticides that, after ingestion by humans or animals, can originate the compound by enzymatic hydrolysis. As most dinitrophenols, dinoseb uncouples oxidative phosphorylation. In this study, distribution, lipid bilayer affinity and kinetics of the metabolic effects of dinoseb were investigated, using mainly the isolated perfused rat liver, but also isolated mitochondria and molecular dynamics simulations...

Quantitative myocardial and blood T1 have recently achieved clinical utility in numerous pathologies, as they provide non-invasive tissue characterization with the potential to replace invasive biopsy. Native T1 time (no contrast agent), changes with myocardial extracellular water (edema, focal or diffuse fibrosis), fat, iron, and amyloid protein content. After contrast, the extracellular volume fraction (ECV) estimates the size of the extracellular space and identifies interstitial disease. Spatially resolved quantification of these biomarkers (so-called T1 mapping and ECV mapping) are steadily becoming diagnostic and prognostically useful tests for several heart muscle diseases, influencing clinical decision-making with a pending second consensus statement due mid-2017...

PURPOSE: Three-dimensional bioactive scaffolds are useful tools for stem cell implant in tissue-engineering. For chondral and subchondral repair, the chondroinductive and osteoinductive property of a scaffold is a major challenge. The scaffolds that aim to osteogenic differentiation have been well studied. However, cartilage cells can hardly be induced for osteogenesis, and monophase scaffolds cannot ideally repair both cartilage and subchondral defects at the same time. METHODS: We developed a novel biphase composite scaffold and observe its application osteochondral defects...
