Diverse forms of unwanted signal variations in mass spectrometry-based metabolomics data adversely affect the accuracies of metabolic profiling. A variety of normalization methods have been developed for addressing this problem. However, their performances vary greatly and depend heavily on the nature of the studied data. Moreover, given the complexity of the actual data, it is not feasible to assess the performance of methods by single criterion. We therefore developed NOREVA to enable performance evaluation of various normalization methods from multiple perspectives...

Biological effects of static magnetic fields (MF) and time-varying MF of electricity (50/60 Hz) appear possible from intensities in the low illitesla range. However, prolonged exposure to 50/60 Hz MF is associated with an increased risk of childhood leukemia at less than one microtesla of time-averaged intensity. And such kind of association is suggested in adults for some blood cancers and senile dementia. The cryptochrome hypothesis has been proposed to explain the association established with childhood leukemia...

This developmental neuroscience study examined the electrophysiological responses (EEG and ERPs) associated with perspective taking and empathic concern in preschool children, as well as their relation to parental empathy dispositions and children's own prosocial behavior. Consistent with a body of previous studies using stimuli depicting somatic pain in both children and adults, larger early (~200 ms) ERPs were identified when perceiving painful versus neutral stimuli. In the slow wave window (~800 ms), a significant interaction of empathy condition and stimulus type was driven by a greater difference between painful and neutral images in the empathic concern condition...

Ethical conflicts are recognized as critical aspects in assessing competence in clinical communication. Moreover, pediatrics residents may face more problems, compared to other disciplines; due to the specific characteristics of the age group receiving services as well as the presence of their families. This study has been conducted with the aim of determining the attitude and perspective of pediatric residents toward ethical conflicts in the field of pediatrics. This descriptive, cross-sectional study was carried out on all residents of Tehran University of Medical Sciences (90 residents), selected through census method, in 2014...

BACKGROUND & AIMS: Availability of directly-acting antivirals (DAAs) has changed the treatment landscape of hepatitis C virus (HCV) infection. The high price of DAAs has restricted their use in several countries. However, in some countries such as India, generic DAAs are available at much cheaper price. This study examined whether generic DAAs could be cost-saving and how long it would take for the treatment to become cost-saving/effective. METHODS: A previously-validated, mathematical model was adapted to the HCV-infected population in India to compare the outcomes of no treatment versus treatment with DAAs...

BACKGROUND: Early-life programming is defined by the adaptive changes made by the fetus in response to an adverse in utero environment. Infantile hemangioma (IH), a vascular anomaly, is the most common tumor of infancy. Here we take IH as the tumor model to propose the stem cell teratogenic hypothesis of tumorigenesis and the potential involvement of the immune system. OBJECTIVES: Teratogenic agents include chemicals, heavy metals, pathogens, and ionizing radiation...

When aiming to improve another person's long-term well-being, people may choose to induce a negative emotion in that person in the short term. We labeled this form of agent-target interpersonal emotion regulation altruistic affect worsening and hypothesized that it may happen when three conditions are met: (a) The agent experiences empathic concern for the target of the affect-worsening process, (b) the negative emotion to be induced helps the target achieve a goal (e.g., anger for confrontation or fear for avoidance), and (c) there is no benefit for the agent...

The present article proposes the perspective of Islamic self (PIS), which is guided by three core principles. First, the Islamic self is shaped by the God's predicament: The life test. Second, the structure of the self and its spiritual virtues represent means to succeed the life test. Third, the complex dynamics of the self can be mathematically formalized into a parsimonious framework. Specifically, the PIS considers the self as a dynamical system characterized by the emergence of self-organized stable and unstable patterns taking the form of positive ("illuminating heart") or negative ("darkened heart") dynamics...

Long-term cessation of oral anticoagulation (OAC) following successful catheter or surgical ablation of atrial fibrillation (AF) is debated. Usually, in the presence of sinus rhythm at serial ECG recordings, the CHADS2, CHA2DS2VASc, and HAS-BLED scores are adopted to guide decision regarding OAC management. Areas covered: The safety of OAC cessation in patients without recurrent AF but with historically elevated risk for thromboembolism remains largely unknown. Taking the cue from two clinical cases, we provide an updated summary of the latest evidence regarding how to manage OAC after a successful atrial fibrillation ablation...

The 'prospective potential support ratio' has been proposed by researchers as a measure that accurately quantifies the burden of ageing, by identifying the fraction of a population that has passed a certain measure of longevity, for example, 17 years of life expectancy. Nevertheless, the prospective potential support ratio usually focuses on the current mortality schedule, or period life expectancy. Instead, in this paper we look at the actual mortality experienced by cohorts in a population, using cohort life tables...

While vaccination is one of the most successful public health interventions, there has always been a parallel movement against vaccines. Apart from scientific factors, the uptake of vaccinations is influenced by historical, political, sociocultural and economic factors. In India, the health system is struggling with logistical weaknesses in taking vaccination to the remotest corners; while on the other hand, some people in places where vaccination is available resist it. Unwillingness to be vaccinated is a growing problem in the developed world...

The human papillomavirus (HPV) vaccine has been linked to a number of serious adverse reactions. The range of symptoms is diverse and they develop in a multi-layered manner over an extended period of time. The argument for the safety and effectiveness of the HPV vaccine overlooks the following flaws: (i) no consideration is given to the genetic basis of autoimmune diseases, and arguments that do not take this into account cannot assure the safety of the vaccine; (ii) the immune evasion mechanisms of HPV, which require the HPV vaccine to maintain an extraordinarily high antibody level for a long period of time for it to be effective, are disregarded; and (iii) the limitations of effectiveness of the vaccine...

Policy agencies are now re-visiting early aspirations that sport, as a form of physical activity, can be an instrument to foster general health and also subjective well-being (SWB). Both of these concepts capture physical and mental health states. SWB also encompasses broader psychological and life satisfaction as well as mood and affect. Past and current policies also identify a link between sport, social capital and SWB. Structural Equation Modelling (SEM) is undertaken on data from the UK's Taking Part survey to investigate the interrelationships between sport, general health, social capital and SWB...

Women with Turner Syndrome (TS) have a variety of medical needs throughout their lives; however, the peripubertal years are particularly challenging. From a medical perspective, the burden of care increases during this time due to growth optimization strategies, frequent health screenings, and puberty induction. Psychologically, girls begin to comprehend the long-term implications of the condition, including their diminished fertility potential. Unfortunately, clear guidelines for how to best approach this stage have not been established...

Recent development of nanoplasmonics has stimulated chemists to utilize plasmonic nanomaterials for efficient and distinctive photochemical applications, and physicists to boldly go inside the "wet" chemistry world. The discovery of plasmon-induced charge separation (PICS) has even accelerated these trends. On the other hand, some confusion is found in discussions about PICS. In this perspective, we focus on differences between PICS and some other phenomena such as co-catalysis effect and plasmonic nanoantenna effect...

Medullary thyroid carcinoma (MTC) represents 3-5% of thyroid cancers. 75% is sporadic and 25% is the dominant component of the hereditary multiple endocrine neoplasia (MEN) type 2 syndromes. Three different subtypes of MEN2, such as MEN2A, MEN2B, and Familial MTC (FMTC) have been defined, based on presence or absence of hyperparathyroidism, pheocromocytoma and characteristic clinical features. Mutations of the RET proto-oncogene are implicated in the pathogenesis of MTC, but there are many other mutational patterns involved...

(1) Background: The communication of hope is complicated, particularly for family caregivers in the context of cancer who struggle to maintain hope for themselves and their loved ones in the face of terminality. In order to understand these complexities, the current study examines the bright and dark sides of how hope is communicated across the cancer journey from the vantage point of bereaved family caregivers; (2) Methods: We analyzed interviews with bereaved family caregivers using qualitative thematic and case oriented strategies to identify patterns in the positive and negative lived experiences when communicating about hope at the end of life; (3) Results: Two overarching patterns of hope emerged...

Humans routinely share information with one another. What drives this behavior? We used neuroimaging to test an account of information selection and sharing that emphasizes inherent reward in self-reflection and connecting with other people. Participants underwent functional MRI while they considered personally reading and sharing New York Times articles. Activity in neural regions involved in positive valuation, self-related processing, and taking the perspective of others was significantly associated with decisions to select and share articles, and scaled with preferences to do so...

Most children born with low weight or intrauterine growth restriction develop catch-up growth that allows them to reach a final height according to their genetic target height. However, in about 15% of children this growth is insufficient. In both, children who have adequate compensatory growth and therefore normal height and children who remain low in childhood, it is necessary to take into account that if puberty starts early, the final height could be compromised. Timely and appropriate intervention could improve it...

In recent years, health behaviour interventions have received a great deal of attention in both research and policy as a means of encouraging people to lead healthier lives. The emphasis of such interventions has varied over time, in terms of level of intervention (e.g. individual vs community) and drawing on different disciplinary perspectives. Recently, a number of critiques have focused on how health behaviour interventions sometimes sideline issues of social context, framing health as a matter of individual choice and, by implication, a personal responsibility...
