Child maltreatment gives rise to atypical patterns of social functioning with peers which might be particularly pronounced in early adolescence when peer influence typically peaks. Yet, few neuroimaging studies in adolescents use peer interaction paradigms to parse neural correlates of distinct maltreatment exposures. This fMRI study examines effects of abuse, neglect, and emotional maltreatment (EM) among 98 youth (n = 58 maltreated; n = 40 matched controls) using an event-related Cyberball paradigm affording assessment of both social exclusion and inclusion across early and mid-adolescence (≤13.5 years, n = 50; >13.5 years, n = 48). Younger adolescents showed increased activation to social exclusion versus inclusion in regions implicated in mentalizing (e.g., superior temporal gyrus). Individual exposure-specific analyses suggested that neglect and EM coincided with less reduction of activation to social exclusion relative to inclusion in the dorsal anterior cingulate cortex/pre-supplementary motor area (dACC/pre-SMA) among younger versus older adolescents. Integrative follow-up analyses showed that EM accounted for this dACC/pre-SMA activation pattern over and above other exposures. Moreover, age-independent results within respective exposure groups revealed that greater magnitude of neglect predicted blunted exclusion-related activity in the parahippocampal gyrus, while EM predicted increased activation to social exclusion in the precuneus/posterior cingulate cortex.

ABSTRACT IMPACT: Our research has the potential to impact human health by identifying gender specific neural markers of emotion regulation in alcohol use disorder. OBJECTIVES/GOALS: Emotion dysregulation is known to be mediated by altered functional organization of the limbic system in addiction. This preliminary study sought to identify gender effects in the association between emotion regulation and resting-state functional connectivity (rsFC) of a negative affect network. METHODS/STUDY POPULATION: 55 individuals receiving treatment for alcohol use disorder (˜2 weeks of abstinence) were recruited for this study and included in this analysis (N=55; Age: M=41.78, SD=10.66; 21 females). RsFC within a network involved in the withdrawal/negative affect stage of addiction and Personality Inventory for DSM-5 (PID-5) metrics were collected from all participants. RsFC data were preprocessed using the Human Connectome Project pipelines. Correlations between (a) rsFC within the withdrawal/negative affect network and the (b) scores of the negative affect subscale of the PID-5 instrument were conducted for each gender separately. RESULTS/ANTICIPATED RESULTS: Independent samples t-test showed a statistically significant gender difference in the PID-5 negative affect scores (Males: M=1.02, SD=0.66; Females: M=1.53, SD=0.51); t(55)=-3.002, p=0.004. Only females showed a significant correlation between rsFC within the withdrawal/negative affect network and negative affect scores of the PID-5 (r=0.51, p<0.05). Fisher r-to-z test showed significant gender differences (z=-1.91; p=0.03, 1-tailed) in correlations coefficients representing the relationship between rsFC of the withdrawal/negative affect network and negative affect (PID-5 subscale). DISCUSSION/SIGNIFICANCE OF FINDINGS: Preliminary findings suggest that the relationship between neural networks mediating emotion regulation and negative affect is only found in females. These results provide valuable data to inform personalized chemical dependency treatment that targets emotion regulation specific to females.

Weight gain among psychiatric inpatients is a widespread phenomenon. This change in body mass index (BMI) can be caused by several factors. Based on recent research, we assume the following factors are related to weight gain during psychiatric inpatient treatment: psychiatric medication, psychiatric diagnosis, sex, age, weight on admission and geographic region of treatment.
876 of originally recruited 2328 patients met the criteria for our analysis. Patients were recruited and examined in mental health care centres in Nigeria (N=265), Japan (N=145) and Western-Europe (Denmark, Germany and Switzerland; N=466).
There was a significant effect of psychiatric medication, psychiatric diagnoses and geographic region, but not age and sex, on BMI changes. Geographic region had a significant effect on BMI change, with Nigerian patients gaining significantly more weight than Japanese and Western European patients. Moreover, geographic region influenced the type of psychiatric medication prescribed and the psychiatric diagnoses. The diagnoses and psychiatric medication prescribed had a significant effect on BMI change.
In conclusion, we consider weight gain as a multifactorial phenomenon that is influenced by several factors. One can discuss a number of explanations for our findings, such as different clinical practices in the geographical regions (prescribing or admission strategies and access-to-care aspects), as well as socio-economic and cultural differences.

The search for life in the Universe is a fundamental problem of astrobiology and modern science. The current progress in the detection of terrestrial-type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures of life with the upcoming ground-based and space missions. To specify the conditions favourable for the origin, development and sustainment of life as we know it in other worlds, we need to understand the nature of global (astrospheric), and local (atmospheric and surface) environments of exoplanets in the habitable zones (HZs) around G-K-M dwarf stars including our young Sun. Global environment is formed by propagated disturbances from the planet-hosting stars in the form of stellar flares, coronal mass ejections, energetic particles and winds collectively known as astrospheric space weather. Its characterization will help in understanding how an exoplanetary ecosystem interacts with its host star, as well as in the specification of the physical, chemical and biochemical conditions that can create favourable and/or detrimental conditions for planetary climate and habitability along with evolution of planetary internal dynamics over geological timescales. A key linkage of (astro)physical, chemical and geological processes can only be understood in the framework of interdisciplinary studies with the incorporation of progress in heliophysics, astrophysics, planetary and Earth sciences. The assessment of the impacts of host stars on the climate and habitability of terrestrial (exo)planets will significantly expand the current definition of the HZ to the biogenic zone and provide new observational strategies for searching for signatures of life. The major goal of this paper is to describe and discuss the current status and recent progress in this interdisciplinary field in light of presentations and discussions during the NASA Nexus for Exoplanetary System Science funded workshop ‘Exoplanetary Space Weather, Climate and Habitability’ and to provide a new roadmap for the future development of the emerging field of exoplanetary science and astrobiology.

Recent proposals suggest early adversity sets in motion particularly chronic and neurobiologically distinct trajectories of internalizing symptoms. However, few prospective studies in high-risk samples delineate distinct trajectories of internalizing symptoms from preschool age onward. We examined trajectories in a high-risk cohort, oversampled for internalizing symptoms, several preschool risk/maintenance factors, and school-age outcomes. Parents of 325 children completed the Strengths and Difficulties Questionnaire on up to four waves of data collection from preschool (3–5 years) to school age (8–9 years) and Preschool Age Psychiatric Assessment interviews at both ages. Multi-informant data were collected on risk factors and symptoms. Growth mixture modelling identified four trajectory classes of internalizing symptoms with stable low, rising low-to-moderate, stable moderate, and stable high symptoms. Children in the stable high symptom trajectory manifested clinically relevant internalizing symptoms, mainly diagnosed with anxiety disorders/depression at preschool and school age. Trajectories differed regarding loss/separation experience, maltreatment, maternal psychopathology, temperament, and stress-hormone regulation with loss/separation, temperament, maternal psychopathology, and stress-hormone regulation (trend) significantly contributing to explained variance. At school age, trajectories continued to differ on symptoms, disorders, and impairment. Our study is among the first to show that severe early adversity may trigger a chronic and neurobiologically distinct internalizing trajectory from preschool age onward.

Preterm birth may be spontaneous or medically indicated for maternal or fetal reasons. Around 20–25% of preterm births (PTB) follow preterm premature rupture of the membranes (PPROM), however the cause of preterm labour is often unknown. It may represent early maturation and activation of the normal labour process or it may be precipitated by pathological causes. The normal process of labour has a diurnal variation with more deliveries occurring at night. Evidence demonstrating that the diurnal variation persists in preterm deliveries suggest that at least a proportion are due to early maturation of the normal process and the logical assumption is that these may be amenable to prevention or effective treatment. Whatever the cause of preterm delivery, there appears to be a common pathway resulting in activation of inflammatory processes. It is important to distinguish the physiological and pathological causes of preterm labour and not to assume that all inflammation is pathological. The distinction is clinically important since pathological causes may be associated with an adverse intrauterine environment, which would be a contraindication to delaying delivery.

Objective: To describe initiatives undertaken by a network of community pediatricians to increase a city's surge capacity for patients presenting with influenza-like illnesses during the 2009 H1N1 influenza A pandemic.
Methods: This was a descriptive quality improvement project detailing the measures employed by a network of private practice community pediatricians in Houston, Texas, caring for both insured and uninsured children.
Results: Four categories of interventions were used: enhanced communication, increasing community pediatrician presence, vaccine distribution, and targeted viral diagnosis and antiviral utilization. Promoting communication between clinicians, families, and an affiliated local tertiary care children's hospital allowed for the efficient coordination of resources as well as a unified and consistent message. Increasing access of families to their primary medical home by employing additional clinicians, extending office hours, and locating additional space served to decrease the number of children with low-acuity illness seen in the local emergency centers. Vaccine distribution was enhanced by effective communication between clinicians and families. Finally, targeted antiviral testing and adherence to national recommendations on antiviral utilization enabled judicious utilization of a limited supply of antiviral medications.
Conclusions: Effective communication and improved access to health care enabled children within the network with influenza-like illnesses to continue to be cared for in their medical home. The measures used in response to novel influenza virus outbreaks can be adapted for other situations requiring increased community surge capacity.

The sprout inhibitor Chlorpropham (CIPC) [isopropyl N-(3 chlorophenyl) carbamate] was found to be an effective sprout inhibitor in stored swedes (Brassica napus L.) under certain conditions. It was ineffective and unnecessary in swedes stored from November to April but necessary for those stored in clamps from March to July. CIPC did not, however, prevent rotting nor arrest normal chemical changes. Rotting developed because of the restricted ventilation necessary for successful use of CIPC and was more severe in mechanically than in hand-harvested roots. The main advantage of using CIPC to extend the storage and feeding life of swedes is that the absence of sprouts makes the handling of the roots much easier.
Friesian bulls fed swedes preserved with CIPC and supplemented with 50% conconcentrates gave satisfactory growth compared with similar bulls offered a diet containing only barley.

Low-temperature photoluminescence (PL) spectroscopy was used to study electronic states associated with threading dislocations (D lines) in strain-relaxed Si1−xGex layers. The structures investigated were grown by ultra-high vacuum chemical vapor deposition (UHV/CVD) at 550 °C and consist of an Si(001) substrate followed by a step-wise graded buffer layer followed by a thick uniform composition Si1−xGex layer. Variations in the PL intensity and peak position of the four D lines after isochronal annealing at temperatures between 600 and 800 °C have been measured. We show that the large energy shift of the D1 line is due to a change in the local band-gap energy at the dislocation core due to strain-driven diffusion of Ge away from the dislocation core with an activation energy of 2.4 eV.

Summary
Introduction
Seed plants show a diversity of adaptations for seed dispersal. These adaptations may involve physical dispersal agents (transport by wind, water, gravity, etc.) or biotic dispersal agents (self-dispersal, or more commonly transport by animals), often combined in various ways, simultaneously, sequentially or as alternatives. The adaptations that are possible or appropriate for a particular species are constrained by its structure and ecology, by its physical and biotic environment, by its history, and by genotypic limits to the extent to which it can vary in response to selective pressures. Adaptations for dispersal interact with and may be conditional upon adaptations for pollination (e.g. the position, number, structure and phenology of flowers) and for seedling establishment (seed size and number, seed protection, seed shape, seed dormancy and seed placement) (Fenner, 1985; Primack, 1987). Seed size has a particularly close interaction with seed dispersal mechanisms (Harper, Lovell & Moore, 1970).
Adaptations for seed dispersal must thus be seen in the context of the complex web of competing and interacting adaptations, constraints and possibilities that affect and ultimately determine the biology of a species. Within a species, the factors affecting seed dispersal may not be uniform. Different populations or individuals of a species may, for example, grow in widely different physical and biotic environments. Even within a single population, the biotic and physical environment may change greatly through time. A population of a pioneering tree species like Rhamnus catharticus or Salix atrocinerea, for example, may pass from a colonizing stage in an open habitat to a late-successional stage in closed woodland.

Clinical reports have suggested that antidepressant medication may contribute to the sexual dysfunction experienced by some depressed patients. A double-blind trial in a non-psychiatric male population compared amitriptyline (tricyclic), mianserin (tetracyclic) and placebo for their effects on nocturnal sexual arousal. In a three-way crossover design active drug or placebo were taken for two weeks preceding measurement of the frequency, amplitude and duration of nocturnal penile tumescence and synchronous sleep indices. Both active compounds significantly decreased the amplitude and the total duration of nocturnal erections. The effects on sleep indices were as previously reported. Few differences were found between the tricyclic and tetracyclic drugs. Some implications of these findings are considered.

1. The interaction between nitrogen and water intake was studied in two ewes and two red deer hinds. They were given pelleted diets, at maintenance level, containing equal amounts of roughage but either rich or poor in nitrogen. The deer received 50 % more food than the sheep. Water was given either in large amounts (sheep 5.01, deer 7.0 1 daily) or in small amounts (sheep 1.1 l, deer 2.4 l daily).
2. Nearly three-quarters of the nitrogen of the high-nitrogen rations but less than half of that of the low-nitrogen rations was excreted in the urine. Restriction of water intake reduced urinary nitrogen excretion by only about 1 g daily, mainly as a result of decreases in the excretion of urea and ammonia, but did not affect the excretion of nitrogen in the faeces.
3. The urinary excretions of creatinine, creatine, hippuric acid, uric acid and allantoin were also examined. The excretion of creatinine was not related to either nitrogen or water intake. The excretion of uric acid and of allantoin was greater in the sheep than in the deer.
4. The concentrations of urea in the plasma and of ammonia in the rumen fluid were measured before and after feeding. The plasma urea value was related to dietary nitrogen intake and was higher on the low- than on the high-water regime. The rumen ammonia value also was related to the nitrogen intake but, while it generally increased after feeding when the high-nitrogen diet was given, it fell almost to zero 2 h after feeding when the low-nitrogen diet was given.
5. The sheep digested dry matter, cellulose and nitrogen a little more fully than the deer. The high-water regime slightly increased the digestibility of dry matter and cellulose but did not affect the digestibility of nitrogen.

The method was based on the minimum dosage of 2,4–dichlorophenoxyacetic acid (2,4–D) that would produce strapping or cupping of cotton leaves. Dilutions of an unknown were applied to cotton cotyledons. The minimum dosage required to produce strapped or cupped leaves two weeks later was approximately 0.05 μg/plant. The results of this bioassay were comparable to tracer methods, but the latter can detect smaller quantities of 2,4–D.
