Excessive existences of nutrients such as phosphate in the aqueous environment remain as a heavy concern although many researches have been reported for dealing with their removal. Based on the understanding toward the interactions of Fe compounds with phosphate and carbonate from many available researches, we designed a very simple and efficient approach for phosphate removal by using in situ generated fresh trivalent Fe composition through the interaction of Fe(II) as FeSO4 on CaCO3 . Addition and agitation of Fe(II) and CaCO3 simultaneously to phosphate solution allowed an amorphous Fe(III)-P or Ca-Fe(III)-P precipitation, with a phosphate removal rate close to 100%, to reduce the residual phosphorus concentration less than 0...

This work aimed at evaluating the toxic effects of in ovo exposure to phenobarbital (PB) and unveiling the mode of action by transcriptome analysis in the embryonic liver of a model avian species, chicken (Gallus gallus). Embryos were initially treated with saline or 1 μg PB /g egg at Hamburger Hamilton Stage (HHS) 1 (1st day), followed by 20 days of incubation to HHS 46. At 21st day, chicks that pipped successfully were euthanized and dissected for assessing the PB caused effects on phenotypes and the liver transcriptome in both genders...

Hypertension disorders (HD) and pre-eclampsia (PRE) are leading causes of maternal deaths worldwide. PRE is associated with vascular endothelial dysfunction and with deregulation of the fibrinolysis pathway genes. Fibrinolysis is the fibrin clot hydrolysis process catalyzed by plasmin, a proteolytic enzyme formed from plasminogen. Plasminogen is cleaved by tissue-type (tPA) and urokinase-type (uPA) activators and inhibited by the plasminogen activator inhibitors type-1 (PAI-1) and type-2 (PAI-2). The whole process maintains blood hemostasis...

OBJECTIVES: The diagnosis and the surgical removal of a brain tumor can have serious impact on the quality of life of a patient. The question rises, whether having more or just less memories of the procedure is better for coping with such an event. Furthermore, for preoperative information of future patients it is important to know how patients process their emotions and memories. The primary objective of this study was to investigate the link between preoperative anxiety, the perioperative experience and the quantity and quality of postoperative memories in patients who underwent intracranial tumor surgery...

The remediation of four different soils contaminated by gasoline was performed using Fenton processes. Herein, the effect of the main physicochemical characteristics of the soils in the Fenton performance is emphasized. Fenton processes were applied in a column system, with and without addition of soluble iron (II), using undisturbed soil samples collected in four regions of the Paraná State (Brazil). Two groups of contaminants were monitored during the remediation process: BTEX (benzene, toluene, ethylbenzene and xylenes) and TRHs (total recoverable hydrocarbons)...

Facial expressions signaling threat and mood-congruent loss have been used to probe abnormal neural reactivity in major depressive disorder (MDD) and may be implicated in genetic vulnerability to MDD. This study investigated electro-cortical reactivity to facial expressions 101 unaffected, adult first degree relatives of probands with MDD and non-relative controls (n = 101). We investigated event-related potentials (ERPs) to five facial expressions of basic emotion: fear, anger, disgust, sadness and happiness under both subliminal (masked) and conscious (unmasked) presentation conditions, and the source localization of group differences...

Neurophysiological research has shown that auditory and motor systems interact during movement to rhythmic auditory stimuli through a process called entrainment. This study explores the neural oscillations underlying auditory-motor entrainment using electroencephalography. Forty young adults were randomly assigned to one of two control conditions, an auditory-only condition or a motor-only condition, prior to a rhythmic auditory-motor synchronization condition (referred to as combined condition). Participants assigned to the auditory-only condition (auditory-first group) listened to 400 trials of auditory stimuli presented every 800ms, while those in the motor-only condition (motor-first group) were asked to tap rhythmically every 800ms without any external stimuli...

Supramolecular diblock copolymers using metal-ligand coordination can be synthesized under ambient conditions by delicate design of the end groups of the homopolymer chains. However, mass spectrometric analysis of such metallo-supramolecular copolymers is challenging. One of the reasons is the nonpolarity of the polymer chains, making it hard to disperse the complexes in electrospray ionization (ESI)-friendly environments. The other difficulty is the noncovalent nature of such copolymers, which is easily disrupted during the ionization...

Oxidation reactions play a central role in organic synthesis, and it is highly desirable that these reactions are mild and occur under catalytic conditions. In Nature, oxidation reactions occur under mild conditions via cascade processes, and furthermore, they often occur in an enantioselective manner with many of them involving molecular oxygen or hydrogen peroxide as the terminal oxidant. Inspired by the reactions in Nature, we have developed a number of Pd(II)-catalyzed cascade reactions under mild oxidative conditions...

The past few years have witnessed the rapid development of carbon dots (CDs) due to their outstanding optical properties and a wide range of applications. However, the design and control of CDs with long-wavelength and multicolor emission are still huge challenges to be addressed for their practical use in different fields. Here, novel nitrogen doped multiple-cores@shell structured CDs with tricolor emissions of red, green and blue were constructed via one pot hydrothermal method from citric acid (CA) and 5-amino-1,10-phenanthroline (Aphen) as reactants and the growth process of CDs was monitored with the reaction time in the synthetic system...

Lysophosphatidic acid (LPA) is a bioactive lipid molecule, which regulates a broad range of pathophysiological processes. Recent studies have demonstrated that LPA modulates electrolyte flux in the intestine and its potential as an anti-diarrheal agent has been suggested. Of six LPA receptors, LPA5 is highly expressed in the intestine. Recent studies by our group have demonstrated activation of Na+ /H+ exchanger 3 (NHE3) by LPA5 . However, much of what has been elucidated was achieved using colonic cell lines that were transfected to express LPA5 ...

Month ordering tasks have been used in experimental settings to obtain measures of working memory (WM) capacity in older/clinical groups based solely on their face validity. We sought to assess the appropriateness of using a month ordering task in other contexts, including clinical settings, as a psychometrically sound WM assessment. To this end, we constructed a month ordering task (ucMOT), studied its reliability (internal consistency and temporal stability), and gathered construct-related and criterion-related validity evidence for its use as a WM assessment...

OBJECTIVES: Ethnic identity development is considered a central task of adolescence and emerging adulthood for ethnic minority individuals. Although the process of developing a coherent ethnic identity has received attention from researchers, there has been little work done to elucidate the content of ethnic identity. This study uses an inductive mixed-methods approach to address 1 aspect of ethnic identity content: typicality, or the degree of perceived similarity individuals feel to their ethnic-racial group...

This study explores the bidirectional and interactional process of acculturation from the perspectives of immigrants and receiving community members (RCMs). Our aim was to understand the experiences and interactions of different ethno-cultural groups and their impact on the functioning and dynamics of multicultural communities. We conducted a cross-national, cross-cultural study of acculturation processes, using interviews collected across two countries (Italy: urban regions of Torino and Lecce; U.S.: Baltimore/Washington corridor) and three distinct groups of immigrants-Moroccans and Albanians in Italy and Latin Americans in the United States-and RCMs in Italy and the United States...

Psychologists have studied small-group and team effectiveness for decades, and although there has been considerable progress, there remain significant challenges. Meta-analyses and systematic research have provided solid evidence for core team cognitive, motivational, affective, and behavioral processes that contribute to team effectiveness and empirical support for interventions that enhance team processes (e.g., team design, composition, training, and leadership); there has been substantial evidence for a science of team effectiveness...

Few industries match the scale of health care. In the United States alone, an estimated 85% of the population has at least 1 health care encounter annually and at least one quarter of these people experience 4 to 9 encounters annually. A single visit requires collaboration among a multidisciplinary group of clinicians, administrative staff, patients, and their loved ones. Multiple visits often occur across different clinicians working in different organizations. Ineffective care coordination and the underlying suboptimal teamwork processes are a public health issue...

Since the Hawthorne studies of the 1920s and 1930s, there has been tremendous progress in the science and the practice of work group effectiveness. We chronicle the evolution of 3 schools of thought concerning work groups that spawned about the time of those studies. We highlight the different emphases of each perspective and how they eventually merged into an integrated view of teamwork. We also illustrate the disciplinary ebbs and flows of work group research over the past quarter century and how many different scholars from diverse institutions are currently contributing to the literature...
