Rodrigo Mogollón, Paulo H R Calil
It has been hypothesized that global warming will strengthen upwelling-favorable winds in the Northern Humboldt Current System (NHCS) as a consequence of the increase of the land-sea thermal gradient along the Peruvian coast. The effect of strengthened winds in this region is assessed with the use of a coupled physical-biogeochemical model forced with projected and climatological winds. Strengthened winds induce an increase in primary production of 2% per latitudinal degree from 9.5°S to 5°S. In some important coastal upwelling sites primary production is reduced...

The effects of anthropogenic global environmental change on biotic and abiotic processes have been reported in aquatic systems across the world. Complex synergies between concurrent environmental stressors and the resilience of the system to regime shifts, which vary in space and time, determine the capacity for marine systems to maintain structure and function with global environmental change. Consequently, an interdisciplinary approach that facilitates the development of new methods for the exchange of knowledge between scientists across multiple scales is required to effectively understand, quantify and predict climate impacts on marine ecosystem services...

OBJECTIVE: Adolescence and young adulthood are developmental periods during the life course that are sometimes associated with heightened stress and engagement in binge eating. Binge eating has been linked to psychiatric comorbidity, poorer physical health, and lower quality of life. However, less is known about protective factors that could buffer against binge eating behaviors. The current study examined the moderating role of resilience on the relationship between perceived stress and binge eating symptoms among emerging adult female college students...

Children are frequently present in homes in which intimate partner violence (IPV) occurs. Following exposure to IPV, children may develop behavioral health difficulties, struggle with regulating emotions, or exhibit aggression. Despite the negative outcomes associated with witnessing IPV, many children also display resilience. Guided by Bronfenbrenner's bioecological model, this study examined person-level, process-level (microsystem), and context-level (mesosystem) factors associated with positive and negative functioning among youth exposed to IPV...

Posttraumatic stress disorder (PTSD) is a prevalent, chronic disorder with high psychiatric morbidity; however, a substantial portion of affected individuals experience remission after onset. Alterations in brain network topology derived from cortical thickness correlations are associated with PTSD, but the effects of remitted symptoms on network topology remain essentially unexplored. In this cross-sectional study, US military veterans ( N  = 317) were partitioned into three diagnostic groups, current PTSD (CURR-PTSD, N  = 101), remitted PTSD with lifetime but no current PTSD (REMIT-PTSD, N  = 35), and trauma-exposed controls (CONTROL, n  = 181)...

Understanding the factors that modulate bacterial community assembly in natural soils is a longstanding challenge in microbial community ecology. In this work, we compared two microbial co-occurrence networks representing bacterial soil communities from two different sections of a pH, temperature and humidity gradient occurring along a western slope of the Andes in the Atacama Desert. In doing so, a topological graph alignment of co-occurrence networks was used to determine the impact of a shift in environmental variables on OTUs taxonomic composition and their relationships...

Laurie Keefer
Psychosocial risk factors linked to brain-gut dysregulation are prevalent across the spectrum of gastrointestinal disorders and are associated with poor patient outcomes. Robust and reproducible data in the areas of behavioural intervention science and the brain-gut axis have led to major advances in patient care, including the routine use of brain-gut psychotherapies to manage digestive symptoms and optimize coping. The logical next step for the emerging field of psychogastroenterology is to develop a scientific framework that enables the identification of those individual characteristics and coping styles that buffer patients against the negative psychological effects of chronic gastrointestinal disorders...

Neuropeptide Y (NPY) expression is tightly linked with the development of stress resilience in rodents and humans. Local NPY injections targeting the basolateral amygdala (BLA) produce long-term behavioral stress resilience in male rats via an unknown mechanism. Previously, we showed that activation of NPY Y1 receptors hyperpolarizes BLA principal neurons (PNs) through inhibition of the hyperpolarization-activated, depolarizing H-current, Ih The present studies tested whether NPY treatment induces stress resilience by modulating Ih NPY (10 pmol) was delivered daily for 5 days bilaterally into the BLA to induce resilience; thereafter the electrophysiological properties of PNs and the expression of Ih in the BLA were characterized...

REVIEW

Plants constantly respond to threats in their environment by balancing their energy needs with growth, defence and survival. Some plants such as the small group of resilient angiosperms, the resurrection plants, do this better than most. Resurrection plants possess the capacity to tolerate desiccation in vegetative tissue and upon watering, regain full metabolic capacity within 72 h. Knowledge of how these plants survive such extremes has advanced in the last few decades, but the molecular mechanics remain elusive...

BACKGROUND AND OBJECTIVES: Posttraumatic stress disorder, a commonly researched mental health outcome associated with trauma, does not develop in the majority of survivors. More common trajectories of adaptation include resilience, and posttraumatic growth (PTG). The objectives of the current study were to: (1) describe posttrauma adaptation profiles in a sample of Israeli male military veterans (N = 448); and (2) to explore the protective factors that promote constructive PTG within two profiles of posttrauma adaptation...

The mathematical model was established to determine the diameter of inhibition zone of the walnut extract on the twelve bacterial species. Type of extraction, concentration, and pathogens were taken as input variables. Two models were used with the aim of designing this system. One of them was developed with artificial neural networks (ANN), and the other was formed with multiple linear regression (MLR). Four common training algorithms were used. Levenberg-Marquardt (LM), Bayesian regulation (BR), scaled conjugate gradient (SCG) and resilient back propagation (RP) were investigated, and the algorithms were compared...

Revocation functionality and hierarchy key delegation are two necessary and crucial requirements to identity-based cryptosystems. Revocable hierarchical identity-based encryption (RHIBE) has attracted a lot of attention in recent years, many RHIBE schemes have been proposed but shown to be either insecure or bounded where they have to fix the maximum hierarchical depth of RHIBE at setup. In this paper, we propose a new unbounded RHIBE scheme with decryption key exposure resilience and with short public system parameters, and prove our RHIBE scheme to be adaptively secure...

Women provide informal caregiving across the world and are often expected to provide care even when ailing themselves. We explore the lived experience of 33 impoverished married Indian women living with HIV, caring for their husbands and/or children living with HIV. Drawing on concepts of authoritative knowledge (AK), self-efficacy and resilience, we found a trajectory that reveals barriers to accessing care, yet we also found that women developed strengths and resiliency. Women gather information, develop 'environ-info,' and deliberatively weigh AK from health workers, family/friends' advice, and their own experiences...

Microscopic viscosity (microviscosity) is a key determinant of diffusion in the cell and defines the rate of biological processes occurring at the nanoscale, including enzyme-driven metabolism and protein folding. Here we establish a Rotor-based Organelle Viscosity Imaging (ROVI) methodology that enables real-time quantitative mapping of cell microviscosity. This approach uses environment sensitive dyes termed molecular rotors, covalently linked to genetically encoded probes to provide compartment specific microviscosity measurements via fluorescence lifetime imaging (FLIM)...

Background: Disability in activities of daily living (ADLs) is a dynamic process and transitions among different disability states are common. However, little is known about factors affecting recovery from disability. We examined the association between frailty and recovery from disability among non-disabled community-dwelling elders. Methods: We studied 1023 adults from the Cardiovascular Health Study (CHS) and 685 adults from the Health and Retirement Study (HRS), who were ≥65 years and had incident disability, defined as having difficulty in ≥1 ADL (dressing, eating, toileting, bathing, transferring, walking across a room)...

Prenatal stress may increase concentrations of maternal glucocorticoids, which restrict fetal growth, with variable impact upon postnatal development. Among key regulators of stress hormone effects are the glucocorticoid receptor (GR) and 11β-hydroxysteroid dehydrogenase-2 (11βHSD2), the enzyme that inactivates glucocorticoid. This study utilized mice selectively bred for social dominance (Dom) or submissiveness (Sub), respectively exhibiting resilience or sensitivity to stress, to test whether stress-induced alterations in placental GR and 11βHSD2 protein expression may mediate divergent effects of prenatal adversity upon postnatal development...

Understanding how microorganisms respond to environmental disturbance is one of the key focuses in microbial ecology. Ammonia-oxidizing bacteria (AOB) and archaea (AOA) are responsible for ammonia oxidation which is a crucial step in the nitrogen cycle. Although the physiology, distribution, and activity of AOA and AOB in soil have been extensively investigated, their recovery from a natural disturbance remains largely unknown. To assess the recovery capacities, including resistance and resilience, of AOA and AOB, soil samples were taken from a reservoir riparian zone which experienced periodically water flooding...
