One of the most challenging problems when trying to recycle urine for different purposes is the removal of urea. In this project we studied an ureolysis system using the bacterium Proteus vulgaris for the transformation of urea to ammonia and its subsequent oxidation to nitrogen at a Pt working electrode. Our system was tested under different pH, microbial reaction times, and urea and bacteria concentrations. Our results indicate that a pH8 is optimal for the combined Proteus vulgaris urease activity and the ammonia oxidation reaction at a Pt electrode...

Eddie M W Tong, Alan Q H Teo
This research examined the regulatory effects of religious concepts on appraisal-emotion processes, focusing on concepts related to God and the relationships between blame appraisals and anger and guilt. In two experimental studies (Studies 1 and 2), blame appraisals were manipulated while participants were exposed to a God or neutral prime, in the context of a failed laboratory task. In an event-sampling study (Study 3), daily blame appraisals and emotions were measured repeatedly in naturalistic environments and their relationships under high perceived moral unacceptability were examined in relation to participants' the tendency to focus on God (God-focus)...

Nephrotoxicity is the main limitation to the dosage and anticancer efficacy of cisplatin. Cisplatin produces tubular epithelial cell apoptosis and necrosis depending on the concentration of the drug. Protection from cisplatin nephrotoxicity must therefore tackle both cell death modes. For its ability to reduce cisplatin reactivity, in addition to its antioxidant effect, we tested and found that N-acetylcysteine (NAC) was most effective at inhibiting cisplatin cytotoxicity. NAC has no significant effect on cell death induced by either cycloheximide or Fas activation, indicating a rather selective action...

BACKGROUND: Only a small percentage of candidates for bariatric surgery ever undergo a procedure for weight loss. Devices duplicating key effects of bariatric surgeries with removable, fully trans-oral implants could extend their benefits to patients unwilling to undergo anatomy-altering abdominal surgeries. METHODS: Thirty-two obese subjects (mean BMI: 42.3) were enrolled in a prospective, multicenter, single-arm, feasibility trial of the first fully trans-oral endoscopic gastrointestinal bypass device...

Animal models have suggested that prenatal ethanol exposure (PEE) alters the κ opioid receptor system. The present study investigated the brain expression of dynorphin and nociceptin/orphanin FQ related genes and assessed anxiety-like behavior in the light-dark box (LDB), shelter-seeking and risk-taking behaviors in the concentric square field (CSF) test, and ethanol-induced locomotion in the open field (OF), in infant or adolescent Wistar rats that were exposed to PEE (0.0 or 2.0 g/kg, intragastrically, gestational days 17-20)...

Chronic insomnia is highly prevalent and associated with significant morbidity (i.e., confers risk for multiple psychiatric and medical disorders, such as depression and hypertension). Therefore, it is essential to identify factors that perpetuate this disorder. One candidate factor in the neurobiology of chronic insomnia is hypothalamic-pituitary-adrenal-axis dysregulation, and in particular, alterations in circadian cortisol rhythmicity. Cortisol secretory patterns, however, fluctuate with both a circadian and an ultradian rhythm (i...

Taylor Kohut, Aleksandar Stulhofer
Despite increasing concerns that adolescent men are vulnerable to developing compulsive pornography use, little research has been done in this area. Given recent theorizing and research concerning moral incongruence, we hypothesized that symptoms of compulsive pornography use should generally be associated with higher levels of pornography use and increased growth in male adolescent pornography use over time, but that this pattern would be attenuated among very religious participants. These hypotheses were tested with mixed effects growth models using two independent panel samples of male Croatian adolescents...

This paper draws from social exchange theory and social cognitive theory to explore moral disengagement as a potential mediator of the relationship between abusive supervision and organizational deviance. We also explore the moderating effect of leader-member exchange (LMX) on this mediated relationship. Results indicate that employees with abusive supervisors engaged in moral disengagement strategies and subsequently in organizational deviance behaviors. Additionally, this relationship was stronger for those higher in LMX...

There is substantial evidence to support the claim that religion can protect against suicide ideation, suicide attempts, and completed suicide. There is also evidence that religion does not always protect against suicidality. More insight is needed into the relationship between suicidal parameters and dimensions of religion. A total of 155 in- and outpatients with major depression from a Christian Mental Health Care institution were included. The following religious factors were assessed: religious service attendance, frequency of prayer, religious salience, type of God representation, and moral objections to suicide (MOS)...

John-Stewart Gordon
This article examines the nature of human dignity against the background of old age and introduces the novel idea of treating human dignity as a formal principle related to the more foundational notion of indignity. The discussion starts with the objection that the notion of human dignity can be used to justify contrary positions and is therefore inconclusive. This pitfall can be averted by appealing to the notion of indignity rather than dignity in one's moral reasoning and decision-making. Cases of indignity are more primary and indicate the violation of the very core of a human being...

Paula Boddington, Katie Featherstone
Continence is a key moment of care that can tell us about the wider care of people living with dementia within acute hospital wards. The spotlight is currently on the quality of hospital care of older people across the UK, yet concerns persist about their poor treatment, neglect, abuse, and discrimination within this setting. Thus, within hospitals, the care of people living with dementia is both a welfare issue and a human rights issue. The challenge of continence care for people living with dementia can be seen as the 'canary in the coal mine' for the unravelling of dignity within the acute setting...

When newborns are admitted to the neonatal intensive care unit for prematurity or other reasons, parents do not take on the role that they were expecting to assume. That is, they do not become the main caregivers of their children. To address this issue, neonatal units are currently trying to involve parents in the care of their children as soon as possible. Interesting experiences regarding this issue have been published. Most of the experiences show that when parents assume part of the responsibility for caring for their children, breastfeeding is prolonged, hospital-stay lengths decrease, weight gain increases and the numbers of readmissions decrease (1-4)...

BACKGROUND: In 2007, Gockel et al. coined the term mesopancreas (MP). In the next 10 years, a limited number of publications about MP have been published, but little is known about the oncological benefit of MP resection. We performed a systematic review of the literature on MP. METHODS: An electronic search was performed in PubMed, EMBASE, Cochrane, Latindex, Scielo, and Koreamed databases until 15 June 2017 to identify all published articles dealing with the subject of MP...

Analysis of seasonal patterns of marine bacterial community structure along horizontal and vertical spatial scales can help to predict long-term responses to climate change. Several recent studies have shown predictable seasonal reoccurrence of bacterial assemblages. However, only a few have assessed temporal variability over both horizontal and vertical spatial scales. Here, we simultaneously studied the bacterial community structure at two different locations and depths in shelf waters of a coastal upwelling system during an annual cycle...

Present-day domestic horses are immensely diverse in their maternally inherited mitochondrial DNA, yet they show very little variation on their paternally inherited Y chromosome. Although it has recently been shown that Y chromosomal diversity in domestic horses was higher at least until the Iron Age, when and why this diversity disappeared remain controversial questions. We genotyped 16 recently discovered Y chromosomal single-nucleotide polymorphisms in 96 ancient Eurasian stallions spanning the early domestication stages (Copper and Bronze Age) to the Middle Ages...

BACKGROUND: Despite a decline in mortality rates from cardiovascular disease (CVD) in the past few decades, the burden of CVD in a contemporary population remains inadequately addressed. Therefore, this study was aimed to investigate secular trends in mortality from coronary artery disease and all-cause mortality over 2 decades, by comparing 2 cohorts of men born 30 years apart and evaluate the prediction of the risk of CVD and all-cause death in a contemporary random sample of Swedish men...

Mechanical circulatory support and heart transplantation are both becoming increasingly common in Fontan patients as this growing cohort of patients is reaching young adulthood. Though device placement may present challenges, the new focus is on selecting the correct cannulation sites and devices at the correct time in order to successfully bridge these challenging patients to heart transplant. Herein, we report the use of multiple mechanical circulatory support strategies tailored to the clinical setting which culminated in 130 days of support prior to cardiac transplantation in a young adult with a failing Fontan circulation...

New super-high-density (SHD) olive orchards designed for mechanical harvesting using over-the-row harvesters are becoming increasingly common around the world. Some studies regarding olive SHD harvesting have focused on the effective removal of the olive fruits; however, the energy applied to the canopy by the harvesting machine that can result in fruit damage, structural damage or extra stress on the trees has been little studied. Using conventional analyses, this study investigates the effects of different nominal speeds and beating frequencies on the removal efficiency and the potential for fruit damage, and it uses remote sensing to determine changes in the plant structures of two varieties of olive trees (‘Manzanilla Cacereña’ and ‘Manzanilla de Sevilla’) planted in SHD orchards harvested by an over-the-row harvester...
