Hyperactive and anxiolytic‐like behaviors result from loss of COUP‐TFI/Nr2f1 in the mouse cortex

The nuclear receptor COUP TFI (also known as Nr2f1) plays major roles in specifying distinct neuronal subtypes during patterning of the neocortical motor and somatosensory cortex, as well as in regulating the longitudinal growth of the hippocampus during development. In humans, mutations in the NR2F1 gene lead to a global developmental delay and intellectual disabilities. While more than 30% of patients show behavioral features of autism spectrum disorder, 16% of haploinsufficient children show signs of hyperactivity and impulsivity. Loss of COUP‐TFI in the cortical mouse primordium results in altered area organization and serotonin distribution, abnormal coordination of voluntary movements and learning and memory deficits. Here, we asked whether absence of COUP‐TFI affects locomotor activity, anxiety, as well as depression. Mice mutant for COUP‐TFI have normal motor coordination, but significant traits of hyperactivity, which does not seem to respond to N‐Methyl‐D‐aspartate (NMDA) antagonists. However, no changes in anxiety, despite increased locomotor performances, were observed in the open field task. On the contrary, elevated plus maze and dark‐light test explorations indicate a decreased anxiety‐like behavior in COUP‐TFI mutant mice. Finally, significantly reduced immobility in the forced swim test and no changes in anhedonia in the sucrose preference task suggest no particular depressive behaviors in mutant mice. Taken together, our study shows that loss of COUP‐TFI leads to increased locomotor activity but less anxiety and contributes in further deciphering the pathophysiology of patients haploinsufficient for NR2F1.
Modeling the Impacts of Manure on Phosphorus Loss in Surface Runoff and Subsurface Drainage.

Simulation of phosphorus (P) transfer from manured agricultural lands to water bodies via surface runoff and subsurface drainage is potentially of great help in evaluating the risks and effects of eutrophication under a range of best management practice scenarios. However, it remains a challenge since few models are capable of providing a reasonably accurate prediction of P losses under manure treatment. The Environmental Policy Integrated Climate (EPIC) model was applied to simulate the impacts on dissolved reactive P (DRP) losses through surface runoff and subsurface drainage from a solid cattle manure-amended corn ( L.)-soybean [ (L.) Merr. ] rotation on a clay loam soil (Vertisol) located in the Lake Erie region. Simulations of DRP loss in surface runoff and tile drainage were satisfactory; however, EPIC did not consider DRP loss directly from manure, weakening its accuracy in the prediction of DRP loss in surface runoff. Having previously drawn on EPIC-predicted surface runoff to initiate SurPhos (Surface Phosphorus and Runoff Model) predictions of DRP losses strictly in surface runoff, no comparison had been made of differences in manure application impacts on EPIC- or SurPhos-predicted DRP losses-accordingly, this was assessed. The SurPhos improved the estimation of DRP loss in surface runoff (Nash-Sutcliffe coefficient, 0.53), especially when large rain events occurred immediately after or within 6 wk of manure application. Generally, EPIC can capture the impacts of manure application on DRP loss in surface runoff and subsurface drainage; however, coupling of the EPIC and SurPhos models increased the accuracy of simulation of runoff DRP losses.
Comparisons between the ON- and OFF-edge motion pathways in the Drosophila brain

Understanding the circuit mechanisms behind motion detection is a long-standing question in visual neuroscience. In Drosophila melanogaster, recently discovered synapse-level connectomes in the optic lobe, particularly in ON-pathway (T4) receptive-field circuits, in concert with physiological studies, suggest a motion model that is increasingly intricate when compared with the ubiquitous Hassenstein-Reichardt model. By contrast, our knowledge of OFF-pathway (T5) has been incomplete. Here, we present a conclusive and comprehensive connectome that, for the first time, integrates detailed connectivity information for inputs to both the T4 and T5 pathways in a single EM dataset covering the entire optic lobe. With novel reconstruction methods using automated synapse prediction suited to such a large connectome, we successfully corroborate previous findings in the T4 pathway and comprehensively identify inputs and receptive fields for T5. Although the two pathways are probably evolutionarily linked and exhibit many similarities, we uncover interesting differences and interactions that may underlie their distinct functional properties.
Testing of the factor structure of the Center for Epidemiologic Studies Depression Scale 10 in a sample of Korean “geese” mothers

Abstract The author’s purpose in this study was to establish the factor structure of the Korean version of the Center for Epidemiologic Studies Depression Scale 10 (CES-D 10) by conducting confirmatory factor analysis based on preexisting models with a sample of Korean transnational mothers (referred to as “geese mothers”). Hundred and fifty-three Korean geese mothers in the USA and New Zealand completed the Korean version of the CES-D 10 questionnaire. The resulting data was subjected to confirmatory factor analysis, which tested three competing models. Our goodness-of-fit indices for the two-factor model indicated an acceptable fit with the current sample. Our results in the present study show that the CES-D 10 can be a useful tool for understanding the concept of depression in Korean geese mothers.
Disinfectant Resistance Profiles and Biofilm Formation Capacity of Escherichia coli Isolated from Retail Chicken.

Disinfectant resistance and biofilm formation capacity are two important characteristics that contribute to the persistence of microorganisms in food processing environments and contamination of food products. This study investigated the susceptibility of 510 Escherichia coli isolates against 5 disinfectants and the prevalence of 10 disinfectant-resistant genes in these isolates. The biofilm formation capacity of 194 isolates was determined, and the correlation between disinfectant resistance and biofilm formation was analyzed. The minimal inhibitory concentrations (MICs) of cetyltrimethylammonium bromide (CTAB), benzalkonium chloride (BC), cetylpyridinium chloride, and chlorhexidine (CHX) against isolates were 32-512, 16-256, 32-256, and 2-32 mg/L, respectively. The MICs of triclosan against 88.43% of isolates were 8-1,024 mg/L, while the MICs for the rest of isolates exceed 2,048 mg/L. The presence of ydgE, ydgF, and qacF genes was significantly correlated with the CHX resistance of E. coli isolates, while the presence of qacF and qacEΔ1 genes was significantly correlated with CTAB and BC resistance, respectively. The biofilm formation capacity (adjusted optical density value) was positively correlated with BC resistance (r = 0.201, p < 0.01) and showed no correlation with other disinfectants. The presence of sugE(p) was positively correlated with biofilm formation, while four genes were negatively correlated with biofilm formation. This study provides useful data on disinfectant resistance and biofilm formation capacity of E. coli contaminating poultry products, which could be helpful in guiding proper disinfectant usage and establishing effective biofilm eradication strategy in food industry.
A short perspective on the long road to effective treatments for Alzheimer's disease

Globally, there are approximately 47 million people living with dementia, and about two thirds of those have Alzheimer's disease (AD). Age is the single biggest risk factor for the vast majority of sporadic AD cases, and because the world's population is aging, the number of people living with AD is set to rise dramatically over the coming decades. There are currently no disease‐modifying treatments for AD, and the few symptomatic agents available have limited impact on the disease. Perhaps surprisingly, there is relatively little activity in the AD research and development field compared with other diseases with a high mortality burden, such as cancer. There is enormous economic incentive to discover and develop the first disease‐modifying treatment, but previous failure has significantly reduced further industrial investment in this field. The short review looks at the historical path trodden to develop treatments and reflects on the journey down the road to truly effective treatments for people living with AD.
Glycogen synthase kinase 3 induces multilineage maturation of human pluripotent stem cell-derived lung progenitors in 3D culture

ABSTRACT Although strategies for directed differentiation of human pluripotent stem cells (hPSCs) into lung and airway have been established, terminal maturation of the cells remains a vexing problem. We show here that in collagen I 3D cultures in the absence of glycogen synthase kinase 3 (GSK3) inhibition, hPSC-derived lung progenitors (LPs) undergo multilineage maturation into proximal cells, type I alveolar epithelial cells and morphologically mature type II cells. Enhanced cell cycling, one of the signaling outputs of GSK3 inhibition, plays a role in the maturation-inhibiting effect of GSK3 inhibition. Using this model, we show NOTCH signaling induced a distal cell fate at the expense of a proximal and ciliated cell fate, whereas WNT signaling promoted a proximal club cell fate, thus implicating both signaling pathways in proximodistal specification in human lung development. These findings establish an approach to achieve multilineage maturation of lung and airway cells from hPSCs, demonstrate a pivotal role of GSK3 in the maturation of lung progenitors and provide novel insight into proximodistal specification during human lung development. Summary: A collagen I 3D culture system that does not rely on reporter lines and is permissive for the specification of all lung and airway lineages is described, allowing investigation of conditions that favor specific lineages.
Support for Resettling Refugees: The Role of Fixed Versus Growth Mind-Sets

In six studies (N = 2,340), we identified one source of people’s differential support for resettling refugees in their country—their beliefs about whether the kind of person someone is can be changed (i.e., a growth mind-set) or is fixed (i.e., a fixed mind-set). U.S. and UK citizens who believed that the kind of person someone is can be changed were more likely to support resettling refugees in their country (Studies 1 and 2). Study 3 identified a causal relationship between the type of mind-set people hold and their support for resettling refugees. Importantly, people with a growth mind-set were more likely to believe that refugees can assimilate in the host society but not that they should assimilate, and the belief that refugees can assimilate mediated the relationship between people’s mind-sets and their support for resettling refugees (Studies 4–6). The findings identify an important antecedent of people’s support for resettling refugees and provide novel insights into the science of mind-sets.
Hypoxia suppresses myofibroblast differentiation by changing RhoA activity

ABSTRACT Fibroblasts show a high range of phenotypic plasticity, including transdifferentiation into myofibroblasts. Myofibroblasts are responsible for generation of the contraction forces that are important for wound healing and scar formation. Overactive myofibroblasts, by contrast, are involved in abnormal scarring. Cell stretching and extracellular signals such as transforming growth factor β can induce the myofibroblastic program, whereas microenvironmental conditions such as reduced tissue oxygenation have an inhibitory effect. We investigated the effects of hypoxia on myofibroblastic properties and linked this to RhoA activity. Hypoxia reversed the myofibroblastic phenotype of primary fibroblasts. This was accompanied by decreased αSMA (ACTA2) expression, alterations in cell contractility, actin reorganization and RhoA activity. We identified a hypoxia-inducible induction of ARHGAP29, which is critically involved in myocardin-related transcription factor-A (MRTF-A) signaling, the differentiation state of myofibroblasts and modulates RhoA activity. This novel link between hypoxia and MRTF-A signaling is likely to be important for ischemia-induced tissue remodeling and the fibrotic response. This article has an associated First Person interview with the first author of the paper. Summary: Under conditions of hypoxia, myofibroblast differentiation is impaired through induction of ARHGAP29, also revealing a link between the HIF and MRTF-A signaling pathways.
Relationship between Sarcopenia and mTOR Pathway in Patients with Colorectal Cancer: Preliminary Report

Abstract Sarcopenia is a syndrome characterized by loss of muscle mass and strength that impacts clinical outcomes and mortality in cancer patients. Although the molecular pathways involved in sarcopenia are not fully elucidated, the decrease in protein synthesis rate appears to be one of the most important events. The objective of this study was to investigate the relationship between sarcopenia and mTOR signaling pathway in patients undergoing colorectal resection surgery. Three groups of patients were assessed: 1) the control group (no cancer, no sarcopenia), 2) the cancer non-sarcopenic group and 3) the cancer sarcopenic group. All individuals were evaluated in relation to presence of sarcopenia and mTOR signaling pathway. Sarcopenia was evaluated by the combination of low muscle mass and low muscle strength, measured using computerized tomography images, and hand grip strength, respectively. Rectus abdominis muscle biopsy was performed at the time of surgery. mTOR pathway was analyzed by MILLIPLEX Map Kit Phospho/total mTOR 2-Plex Magnetic Bead Panel. Results were presented by phosphor/total mTOR ratio. Independent T test, Kruskal-Wallis test, and Dunn-Bonferroni post hoc were performed for statistical analysis and P < 0.05 was considered. Thirty-six patients and five controls were evaluated. A total of 13 cancer patients (36.1%) had sarcopenia. The phospho/total mTOR ratio was different between the control group (0.167 MFI) and the cancer non-sarcopenic group (0.055 MFI) (P = 0.026) as well as between the control group (0.167 MFI) and the cancer sarcopenic group (0.0049 MFI) (P = 0.041). No difference was observed on the median phospho/total mTOR ratio between the cancer groups (P > 0.05). More research is needed to extrapolate these results.
A novel role for the extracellular matrix glycoprotein‐Tenascin‐X in gastric function

Tenascin X (TNX) functions in the extracellular matrix of skin and joints where it maintains correct intercellular connections and tissue architecture TNX is associated exclusively with vagal‐afferent endings and some myenteric neurones in mouse and human stomach, respectively. TNX‐deficient mice have accelerated gastric emptying and hypersensitivity of gastric vagal mechanoreceptors that can be normalized by an inhibitor of vagal‐afferent sensitivity. Cultured nodose ganglion neurones showed no changes in response to capsaicin, cholecystokinin and potassium chloride in TNX‐deficient mice. TNX‐deficient patients have upper gastric dysfunction consistent with those in a mouse model. Our translational studies suggest that abnormal gastric sensory function may explain the upper gut symptoms present in TNX deficient patients, thus making it important to study gastric physiology. TNX deficiency should be evaluated routinely in patients with connective tissue abnormalities, which will enable a better understanding of its role and allow targeted treatment. For example, inhibitors of vagal afferents‐baclofen could be beneficial in patients. These hypotheses need confirmation via targeted clinical trials.
Gold-substituted Silver-intensified Peroxidase Immunolabeling for FIB-SEM Imaging

Modern electron microscopy offers a wide variety of tools to investigate the ultrastructural organization of cells and tissues and to accurately pinpoint intracellular localizations of macromolecules of interest. New volumetric electron microscopy techniques and new instrumentation provide unique opportunities for high-throughput analysis of comparatively large volumes of tissue and their complete reconstitution in three-dimensional (3D) electron microscopy. However, due to a variety of technical issues such as the limited penetration of label into the tissue, low antigen preservation, substantial electron density of secondary detection reagents, and many others, the adaptation of immuno-detection techniques for use with such 3D imaging methods as focused ion beam–scanning electron microscopy (FIB-SEM) has been challenging. Here, we describe a sample preparation method for 3D FIB-SEM, which results in an optimal preservation and staining of ultrastructural details at a resolution necessary for tracing immunolabeled neuronal structures and detailed reconstruction of synapses. This technique is applicable to neuronal and non-neuronal cells, tissues, and a wide variety of antigens.
Use of vasopressin in the treatment of refractory septic shock

Objective To evaluate the short-term evolution of patients with septic shock refractory to norepinephrine treated with vasopressin in an intensive care unit of a university hospital. Methods An unmatched retrospective study (case series) was performed. Clinical, laboratory, and anthropometric data were collected from patients who received vasopressin infusion for treatment of catecholamine-refractory shock from December 2014 to June 2016. For the assessment of severity, APACHE II and SOFA scores were used. The main outcome was mortality at 3 and 30 days. Results A total of 80 patients were included, of which 60% were male. In 86.3% of the cases, APACHE II was observed in the highest ranges (> 20). The 30-day mortality was 86.2%, and 75% of the patients died within 72 hours after starting vasopressin. Conclusion The series evaluated had high mortality in the first 72 hours of treatment with vasopressin. The use of vasopressin in patients who are refractory to norepinephrine had little or no impact on mortality. It was not possible to exclude the possibility that the high mortality in the present study was linked to the relatively late onset (after established refractoriness of norepinephrine) of vasopressin; this hypothesis should be further evaluated in a randomized study.
Development of a liver‐specific Tet‐off AAV8 vector for improved safety of insulin gene therapy for diabetes

Diabetes mellitus is caused by a partial or complete lack of insulin production in the body. We have previously shown that a single injection of an adeno‐associated virus serotype 8 (AAV8) vector carrying a modified and codon optimized human insulin gene induced hepatic production of insulin and corrected streptozotocin (STZ)‐induced diabetes in mice for more than 1 year. Insulin production was constitutive, analogous to long‐acting insulin therapy.
Time and support do not heal all wounds: Mental health correlates of past bullying among college students

Abstract Objective: We examined whether perceptions of being bullied during middle and high school were associated with depressive, anxiety, and posttraumatic stress disorder (PTSD) symptoms during college. We also examined whether perceived social support (PSS) mediated the association between bullying and symptoms, and explored whether parental, peer, or other sources of support was most beneficial. Participants: Undergraduates (N = 270) from an urban commuter college in the Northeast participated during Spring 2013 or Fall 2015. Methods: Psychometrically sound self-report measures were used to assess symptoms and perceptions of bullying and social support. Results: As hypothesized, bullying was associated with more symptoms, and PSS significantly mediated the associations between bullying and symptoms of PTSD and depression. Conclusion: The college years provide another opportunity to address the effects of middle and high school bullying. Receiving current support for past bullying is beneficial but is not enough, college counseling services are needed to reduce symptoms.
Plasma‐based biomaterials for the treatment of cutaneous radiation injury

Cutaneous wounds caused by an exposure to high doses of ionizing radiation remain a therapeutic challenge. While new experimental strategies for treatment are being developed, there are currently no off‐the‐shelf therapies for the treatment of cutaneous radiation injury that have been proven to promote repair of the damaged tissues. Plasma‐based biomaterials are biologically active biomaterials made from platelet enriched plasma, which can be made into both solid and semi‐solid forms, are inexpensive, and are available as off‐the‐shelf, nonrefrigerated products. In this study, the use of plasma‐based biomaterials for the mitigation of acute and late toxicity for cutaneous radiation injury was investigated using a mouse model. A 2‐cm diameter circle of the dorsal skin was irradiated with a single dose of 35 Gy followed by topical treatment with plasma‐based biomaterial or vehicle once daily for 5 weeks postirradiation. Weekly imaging demonstrated more complete wound resolution in the plasma‐based biomaterial vs. vehicle group which became statistically significant (p < 0.05) at weeks 12, 13, and 14 postmaximum wound area. Despite more complete wound healing, at 9 and 17 weeks postirradiation, there was no statistically significant difference in collagen deposition or skin thickness between the plasma‐based biomaterial and vehicle groups based on Masson trichrome staining nor was there a statistically significant difference in inflammatory or fibrosis‐related gene expression between the groups. Although significant improvement was not observed for late toxicity, plasma‐based biomaterials were effective at promoting wound closure, thus helping to mitigate acute toxicity.
Recent Developments of Acoustic Energy Harvesting: A Review

Acoustic energy is a type of environmental energy source that can be scavenged and converted into electrical energy for small-scale power applications. In general, incident sound power density is low and structural design for acoustic energy harvesting (AEH) is crucial. This review article summarizes the mechanisms of AEH, which include the Helmholtz resonator approach, the quarter-wavelength resonator approach, and the acoustic metamaterial approach. The details of recently proposed AEH devices and mechanisms are carefully reviewed and compared. Because acoustic metamaterials have the advantages of compactness, effectiveness, and flexibility, it is suggested that the emerging metamaterial-based AEH technique is highly suitable for further development. It is demonstrated that the AEH technique will become an essential part of the environmental energy-harvesting research field. As a multidisciplinary research topic, the major challenge is to integrate AEH devices into engineering structures and make composite structures smarter to achieve large-scale AEH.
