#1
REVIEW
Gregory I Giles, Muhammad Jawad Nasim, Wesam Ali, Claus Jacob
Fifteen years ago, in 2001, the concept of "Reactive Sulfur Species" or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected avenues in research and product development. During this time, it has become apparent that molecules with sulfur-containing functional groups are not just the passive "victims" of oxidative stress or simple conveyors of signals in cells, but can also be stressors in their own right, with pivotal roles in cellular function and homeostasis...

Sylvain Dolédec, Jessica Tilbian, Núria Bonada
CONTEXT: Understanding natural temporal changes in Mediterranean rivers with contrasting flow regimes in relation to those of temperate rivers may prove helpful in predicting effects of climate change on aquatic biodiversity. GOAL: We aimed to compare temporal variability in taxonomic and trait compositions of nearly natural rivers in two climatic regions with varying flow regimes to address the effects of future climate changes on aquatic biodiversity in reference conditions...

How cells control the overall size and growth of membrane-bound organelles is an important unanswered question of cell biology. Fission yeast cells maintain a nuclear size proportional to cellular size, resulting in a constant ratio between nuclear and cellular volumes (N/C ratio). We have conducted a genome-wide visual screen of a fission yeast gene deletion collection for viable mutants altered in their N/C ratio, and have found that defects in both nucleocytoplasmic mRNA transport and lipid synthesis alter the N/C ratio...

OBJECTIVE: The question whether musical training is associated with enhanced auditory and cognitive abilities in children is of considerable interest. In the present study, we compared children with music training versus those without music training across a range of auditory and cognitive measures, including the ability to detect implicitly statistical regularities in input (statistical learning). METHODS: Statistical learning of regularities embedded in auditory and visual stimuli was measured in musically trained and age-matched untrained children between the ages of 9-11years...

Wiley Sinkus, Virginia Shervette, Joseph Ballenger, Lou Ann Reed, Craig Plante, Byron White
Mercury (Hg) concentrations and nitrogen (δ(15)N) and carbon (δ(13)C) stable isotopic ratios were measured to assess differences in Hg bioaccumulation in four predatory fish species (Mycteroperca microlepis, Lutjanus campechanus, Caulolatilus microps, and Serioli dumerili) of high commercial and recreational importance in Atlantic waters of the southeastern US. Positive relationships existed between Hg and length, weight, and age, for all species, strongest for M. microlepis and L. campechanus. Intraspecific Hg concentrations also strongly correlated with δ(15)N for all species, and δ(13)C for only L...

AIMS: There is a lack of evidence on the optimal approach for treating acute cystitis in women with diabetes. We performed an outpatient database study to compare management of women with and without diabetes and to assess the effect of treatment duration on early and late recurrence. METHODS: We used the EPIC Clarity database (electronic medical record system) to identify all female patients aged ≥18years with acute cystitis in two family medicine clinics and a urology department...

Eva Wimmer, Monika Rothweiler, Martina Penke
For children with sensorineural hearing loss the ability to understand wh-questions might be particularly challenging because they often have only restricted access to spoken language input during optimal periods of language acquisition. In previous research it has been suggested that this restricted input during critical stages in language acquisition might lead to syntactic deficits that persist into adolescence. In this study we want to pursue this issue by investigating the comprehension of wh-questions in German children with bilateral sensorineural hearing loss...

Corrado Caudek, Francesco Ceccarini, Claudio Sica
The facial dot-probe task is one of the most common experimental paradigms used to assess attentional bias toward emotional information. In recent years, however, the psychometric properties of this paradigm have been questioned. In the present study, attentional bias to emotional face stimuli was measured with dynamic and static images of realistic human faces in 97 college students (63 women) who underwent either a positive or a negative mood-induction prior to the experiment. We controlled the bottom-up salience of the stimuli in order to dissociate the top-down orienting of attention from the effects of the bottom-up physical properties of the stimuli...

Well known in popular culture, the 1964 murder of Kitty Genovese in Queens, New York, became famous because not one of an alleged 38 bystanders called police until it was too late. Within psychology, this singular event inspired the study of bystander intervention. With the spotlight of history focused on Ms. Genovese and bystanders, other events, also profound for what they tell us about human social behavior, have escaped public notice. Based on archival records and current interviews, this article describes the three issues linked to Genovese...

Megan R Gunnar
This review provides a broad overview of my research group's work on social buffering in human development in the context of the field. Much of the focus is on social buffering of the hypothalamic-pituitary-adrenocortical (HPA) system, one of the two major arms of the mammalian stress system. This focus reflects the centrality of the HPA system in research on social buffering in the fields of developmental psychobiology and developmental science. However, buffering of the cardiovascular and autonomic nervous system is also discussed...

Interactions between plants and phytophagous insects play an important part in shaping the biochemical composition of plants. Reciprocally plant metabolites can influence major life history traits in these insects and largely contribute to their fitness. Plant rhizospheric microorganisms are an important biotic factor modulating plant metabolites and adaptation to stress. While plant-insects or plant-microorganisms interactions and their consequences on the plant metabolite signature are well-documented, the impact of soil microbial communities on plant defenses against phytophagous insects remains poorly known...

Amy L Toth
In social species, there is a fundamental trade-off between 'me' and 'we'; that is, should I reproduce, or should I work to help others to reproduce? In this issue of Molecular Ecology, Okada et al. () delve into the evolution and genetic mechanisms of this core question, focusing on social caste formation in insects. The authors take advantage of a unique ant in the genus Diacamma, which has secondarily lost the classic, highly different queens and workers found in many other ants, bees and wasps. Instead, Diacamma ant castes are decided via aggressive dominance interactions among adult females, similar to dominance hierarchies seen in primitively social insects and many social vertebrates...

Narcolepsy is a disabling neurological disorder of sleepiness linked to the loss of neurons producing orexin neuropeptides in the hypothalamus. Two well characterized phenotypic mouse models of narcolepsy, loss-of-function (orexin-knockout) and progressive loss of orexin (orexin/ataxin-3) exist. The open question is whether the proteomics signatures of the hypothalamus would be different between the two models. To address this gap, we utilized a label-free proteomics approach and conducted a hypothalamic proteome analysis by comparing each disease model to that of wild type...

REVIEW
Catherine M Buckley, Jason S King
Macropinocytosis is a mechanism for the non-specific bulk uptake and internalisation of extracellular fluid. This plays specific and distinct roles in diverse cell types such as macrophages, dendritic cells and neurons, by allowing cells to sample their environment, extract extracellular nutrients and regulate plasma membrane turnover. Macropinocytosis has recently been implicated in several diseases including cancer, neurodegenerative diseases and atherosclerosis. Uptake by macropinocytosis is also exploited by several intracellular pathogens to gain entry into host cells...
