The impact of environmental change and anthropogenic stressors on coastal marine systems will strongly depend on changes in the magnitude and composition of organic matter exported from the water column to the seafloor. Knowledge of vertical export in the Baltic Sea is synthesised to illustrate how organic matter deposition will respond to climate warming, climate-related changes in freshwater runoff, and ocean acidification. Pelagic heterotrophic processes are suggested to become more important in a future warmer climate, with negative feedbacks to organic matter deposition to the seafloor...

Healing and regeneration of bone injuries, particularly those that are associated with large bone defects, are a complicated process. There is growing interest in the application of osteoinductive and osteogenic growth factors and mesenchymal stem cells (MSCs) in order to significantly improve bone repair and regeneration. MSCs are multipotent stromal stem cells that can be harvested from many different sources and differentiated into a variety of cell types, such as preosteogenic chondroblasts and osteoblasts...

Context • Pain from osteoarthritis is associated with peripheral nociception and central pain processing. Given the unmet need for innovative, effective, and well-tolerated therapies, many patients, after looking for more satisfactory alternatives, decide to use complementary and alternative modalities. The analgesic mechanism of subcutaneous injections of diluted bee venom into an acupoint is thought to be part of an anti-inflammatory effect and the central modulation of pain processing. Objectives • Using the rat model of collagenase-induced osteoarthritis (CIOA), the study intended to investigate the analgesic effects of bee venom acupuncture (BVA) as they are related to the acupuncture points and dosage used and to determine whether the analgesic mechanisms of BVA for pain were mediated by opioid or adrenergic receptors...

Despite intense nationwide efforts to improve healthy eating and physical activity across the lifespan, progress has plateaued. Moreover, health inequities remain. Frameworks that integrate research, clinical practice, policy, and community resources to address weight-related behaviors are needed. Implementation and evaluation of integration efforts also remain a challenge. The purpose of this paper is to: (1) Describe the planning and development process of an integrator entity, HEAL (Healthy Eating and Activity across the Lifespan); (2) present outcomes of the HEAL development process including the HEAL vision, mission, and values statements; (3) define the planned integrator functions of HEAL; and (4) describe the ongoing evaluation of the integration process...

High-content, imaging-based screens now routinely generate data on a scale that precludes manual verification and interrogation. Software applying machine learning has become an essential tool to automate analysis, but these methods require annotated examples to learn from. Efficiently exploring large datasets to find relevant examples remains a challenging bottleneck. Here, we present Advanced Cell Classifier (ACC), a graphical software package for phenotypic analysis that addresses these difficulties. ACC applies machine-learning and image-analysis methods to high-content data generated by large-scale, cell-based experiments...

Methionine enkephalin ([Met(5)]-enkephalin, Opioid growth factor (OGF)) is a small neuropeptide with growth-related as well as immunomodulatory properties. OGF is distributed widely throughout the body, is both autocrine and paracrine produced, and has a very short half-life in serum. In addition to its neurotransmitter functions, OGF inhibits cell replication of a wide variety of cells involved in the autoimmune process. In this preclinical study, mice were immunized with myelin oligodendrocytic glycoprotein (MOG35-55) to establish a chronic progressive form of autoimmune encephalomyelitis (EAE), and serum enkephalin levels were assessed throughout the disease as well as in response to OGF therapy in order to determine whether OGF may be a biological marker for EAE and multiple sclerosis...

Individuals with autism spectrum disorder (ASD) commonly show global deficits in the processing of facial emotion, including impairments in emotion recognition and slowed processing of emotional faces. Growing evidence has suggested that these challenges may increase with age, perhaps due to minimal improvement with age in individuals with ASD. In the present study, we explored the role of age, emotion type and emotion intensity in face processing for individuals with and without ASD. Twelve- and 18 to 22- year-old children with and without ASD participated...

Transcription factors (TFs) are key actors of the control of gene expression and consequently of every major process within cells, ranging from cell fate determination, cell cycle control and response to environment. Their ectopic expression has proven high potential in reprogramming cells for regenerative medicine; ontogenesis studies and cell based modelling. Direct delivery of proteins could represent an alternative to current reprogramming methods using gene transfer but still needs technological improvements...

Antibiotic resistance is becoming a global threat and overuse of antibiotics in aquaculture disease control worsens the situation. To reduce the risk of drug resistance developed in aquaculture, safer biocontrol programs are needed. Antivirulence therapy, with less chance for developing drug resistance, is a promising approach. To facilitate antivirulence inhibitor design against Vibrio anguillarum, a serious aquaculture pathogen, we present crystal structures for isochorismatase domains of AngB and VabB, which are required to synthesize siderophore, a critical virulence factor...

The aim of this study was to develop the economic and effective buffer system for microalgae mass cultivation using industrial flue gas. Due to the continuous flue gas supplement, culture media acidified, therefore cell growth inhibited. Although buffering agent was added, this result increase in cost for overall culture process. Therefore combined buffer system of bicarbonate and phosphate (BP) for large-scale use was investigated. The bicarbonate buffer system generated from CO2 dissolution, additionally phosphate buffer system improves the buffer performance under the continuous CO2 supplementation from flue gas...

Microbial fuel cell (MFC) is a promising device for energy generation and organic waste treatment simultaneously by electrochemically active bacteria (EAB). In this study, an integrated aerobic-anaerobic strategy was developed to improve the performance of P. aeruginosa-inoculated MFC. With an aerobic start-up and following an anaerobic discharge process, the current density of MFC reached a maximum of 99.80µA/cm(2), which was 91.6% higher than the MFC with conventional constant-anaerobic operation. Cyclic voltammetry and HPLC analysis showed that aerobic start-up significantly increased electron shuttle (pyocyanin) production (76% higher than the constant-anaerobic MFC)...

A series of MgO-based adsorbents were prepared through solution-combustion synthesis and ball-milling process. The prepared MgO-based powders were characterized using X-ray diffraction, scanning electron microscopy, N2 physisorption measurements, and employed as potential adsorbents for CO2 adsorption. The influence of structural and textural properties of these adsorbents over the CO2 adsorption behaviour was also investigated. The results showed that MgO-based products prepared by solution-combustion and ball-milling processes, were highly porous, fluffy, nanocrystalline structures in nature, which are unique physico-chemical properties that significantly contribute to enhance their CO2 adsorption...

Minimizing particles in water is a key goal for improving drinking water quality and safety. The media filtration process, as the last step of the solid-liquid separation process, is largely influenced by the characteristics of flocs, which are formed and controlled within the coagulation process. In a laboratory-based study, the impacts of the physical characteristics of flocs formed using aluminum sulfate on the filtration treatment of two comparative water samples were investigated using a photometric dispersion analyzer and a filterability apparatus...

The presence of noise usually impairs the processing of a stimulus. Here, we studied the effects of noise on face processing and show, for the first time, that adaptation to noise patterns has beneficial effects on face perception. We used noiseless faces that were either surrounded by random noise or presented on a uniform background as stimuli. In addition, the faces were either preceded by noise adaptors or not. Moreover, we varied the statistics of the noise so that its spectral slope either matched that of the faces or it was steeper or shallower...
