Although on-line chemical cleaning has been extensively employed for maintaining the MBR permeability, little attention has been given to the negative impacts of such prevalent membrane cleaning practice. This study thus comparatively investigated the potential release of dissolved organic matter (DOM) from activated sludge upon the exposure to different kinds of frequently-used cleaning reagents, i.e. NaClO, H2O2, HCl and NaOH. It was found that NaClO at 50 and 80 mg L(-1) triggered significant release of DOM, while NaOH strongly promoted soluble nitrogen release...

After diagnosis, veterans with posttraumatic stress disorder (PTSD) display significant variability in the natural course of illness (Bonanno et al., 2012)). Cross-sectional work reveals that abnormal neural response during emotion reactivity-measured using the late positive potential (LPP)-correlates with PTSD symptom severity; however, whether the LPP during emotional reactivity and regulation predicts symptoms over time is unknown. The current study examined the LPP during emotion reactivity and regulation as predictors of PTSD symptoms over one year in OEF/OIF/OND combat-exposed veterans...

Increased emphasis on mechanisms of treatment effectiveness, biomarker predictors, and objective indicators of treatment response has sparked interest in integrated, translational treatment outcomes trials. The PROlonGed ExpoSure and Sertraline Trial (PROGrESS) is one such randomized controlled trial (RCT) focused on a key question in clinical management of posttraumatic stress disorder (PTSD) - the comparative and combined effectiveness of medication and psychotherapy. PROGrESS employs a state of the art trial design to examine psychotherapy and medication effects across three conditions: 1) Prolonged Exposure (PE) plus pill placebo, 2) Sertraline (SERT) plus Enhanced Medication Management (EMM), and 3) Combined treatment (PE/SERT)...

For many veterans returning from combat in Iraq and Afghanistan, the transition from military to civilian life is complicated by an array of postdeployment stressors. In addition to significant stress associated with reintegration after deployment, many returning veterans also contend with the added burden conferred by PTSD symptoms. While the relationship between PTSD symptoms and the neurobiological substrates of emotion dysregulation has begun to be studied, even less is known about the effects of postdeployment stress on neural function...

In temperate climates, tree growth dormancy usually ensures the annual nature of tree rings, but in tropical environments, determination of annual periodicity can be more complex. The purposes of the work are as follows: (1) to generate a reliable tree-ring width chronology for Prioria copaifera Griseb. (Leguminoceae), a tropical tree species dwelling in the Atrato River floodplains, Colombia; (2) to assess the climate signal recorded by the tree-ring records; and (3) to validate the annual periodicity of the tree rings using independent methods...

Sulfur dioxide (SO2) is a dangerous environmental pollutant. Excessive intake of it may cause some respiratory diseases and even lung cancer. The development of effective methods for detection of SO2 is of great importance for the environment and physiology. Herein, we have designed and synthesized a novel two-photon (TP) and deep-red emission ratiometric fluorescent probe (CP) for detection of SO2. Notably, the novel probe CP exhibited ultrafast response to SO2 in less than 5 s and displayed a great emission shift (195 nm) and a large emission signal ratio variation (enhancement from 0...

Posttraumatic stress disorder (PTSD) is associated with poorer performance on neuropsychological tests in veterans. However, prior studies have generally compared individuals with PTSD to control groups, often excluding individuals with moderate symptoms. The present study evaluated neuropsychological performance among OEF/OIF/OND veterans as a function of overall PTSD severity, while also exploring potential associations between cognitive performance and PTSD symptom clusters. Using a brief neuropsychological battery, clinical interviews, and self-report instruments, we evaluated neuropsychological and psychiatric functioning in 90 OEF/OIF/OND veterans...

Heart failure with preserved ejection fraction (HFpEF) is now an emerging cardiovascular epidemic, being identified as the main phenotype observed in clinical practice. It is more associated with female gender, advanced age and comorbidities such as hypertension, diabetes, obesity and chronic kidney disease. Amyloidosis is a clinical disorder characterized by the deposition of aggregates of insoluble fibrils originating from proteins that exhibit anomalous folding. Recently, pictures of senile amyloidosis have been described in patients with HFpEF, demonstrating the need for clinical cardiologists to investigate this etiology in suspect cases...

Post-traumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are two of the most common consequences of combat deployment. Estimates of comorbidity of PTSD and mTBI are as high as 42% in combat exposed Operation Enduring Freedom, Operation Iraqi Freedom and Operation New Dawn (OEF/OIF/OND) Veterans. Combat deployed Veterans with PTSD and/or mTBI exhibit deficits in classic executive function (EF) tasks. Similarly, the extant neuroimaging literature consistently indicates abnormalities of the ventromedial prefrontal cortex (vmPFC) and amygdala/hippocampal complex in these individuals...
