Rhamnus prinoides (gesho) extract Inhibits Streptococcus mutans and Candida albicans Polymicrobial Biofilm Formation

Polymicrobial biofilms contain multiple microbial species encased in an extracellular polymeric matrix. Synergistic interactions within polymicrobial biofilms contribute to elevated antibiotic resistance and chronic infections; furthermore, prevention and treatment is still an unresolved issue. The yeast Candida albicans and the Gram positive bacterium Streptococcus mutans are biofilm-forming oral pathogens that interact mutualistically, and were investigated in this work. Crystal violet-based biofilm formation assays were used to measure the effect of extracts from Rhamnus prinoides (gesho), an East African plant used in traditional medicine, on biofilm formation. The biomass of dual species biofilms was 70% greater than single-species biofilms, indicating a synergistic interaction. Treatment with gesho extracts reduced both single-species and polymicrobial biofilm biomass by more than 90% relative to controls. Imaging by epifluorescence microscopy supported the findings of the biofilm formation assays. In conclusion, gesho exhibited significant potential for use as an anti-biofilm agent and warrants further investigation.

Research on Livestock Carrying Capacity of Arid Pastoral Areas Based on Dynamic Water–Forage–Livestock Balance in OtogBanner, China

There are nonequilibrium characteristics of grassland ecosystems driven by water, and constraints on the development scale of artificially irrigated grassland caused by the lack of water resources in arid pastoral areas. Based on the interaction of water, forage, and livestock, this study built a model of livestock-carrying capacity within the dynamic water–forage–livestock balance, to analyze the livestock carrying capacity of arid pastoral areas. The results showed that compared with the fixed livestock carrying capacity of 1.0898 million sheep units with a dynamic forage–livestock balance, the livestock carrying capacity based on the dynamic water–forage–livestock balance of OtogBanner were in a multi-equilibrium state due to the fluctuation of rangeland productivity caused by a change in precipitation conditions and the adjustment of the tame grassland irrigation scale caused by the change in water demand of other water users in the pastoral area. Under the conditions of the wet, normal, and dry years, the livestock carrying capacity was 1.632 million standard sheep units under the 26.5 thousand hm2 tame grassland developing areas, 1.3037 million standard sheep units under the 25.9 thousand hm2 tame grassland developing areas, and 0.9155 million standard sheep units respectively under 22.4 thousand hm2 tame grassland developing areas. This fluctuation change was more prominent in the pastoral areas with rangeland as the key field. Besides this, the model could effectively identify the predicament of water and forage resources. At present, the overload of forage resources and water resources coexisted in the pastoral area of OtogBanner, and an important reason for this was that the distribution of water and forage resources was poorly matched with the mode of animal husbandry production. The value of 1.3037 million sheep units was recommended to the livestock-carrying capacity of OtogBanner according to the model. This study could provide a new method for the calculation of livestock carrying capacity, and offered a scientific basis for the protection of the grassland ecological environment and the sustainable development of animal husbandry in the arid pastoral area of OtogBanner.

Cell adhesion promoted by a unique Shigella IpaA vinculin- and talin-binding site

During Shigella cell invasion, the IpaA effector targets the focal adhesion protein vinculin through three vinculin-binding sites (VBSs). Here, we report that IpaA VBS3 also binds to talin. The 2.5 Å resolution crystal structure indicates that IpaA VBS3 forms a tightly folded α-helical bundle with talin H1-H4, contrasting with bundle unraveling upon vinculin interaction. High-affinity binding of Ipa VBS3 to talin H1-H4 requires a core of hydrophobic residues conserved in vinculin binding and a pair of electrostatic interactions accounting for talin binding specificity. IpaA VBS3 does not bind to talin H1-H5 suggesting the targeting of partially activated stretched talin but not inactive talin. Consistently, IpaA VBS3 labeled filopodial and nascent adhesions and regulated their formation through talin binding. In addition, talin-binding by IpaA VBS3 was required for bacterial capture by filopodia during Shigella invasion and for the stabilization of focal adhesions in infected cells. These findings point to the functional diversity of VBSs and a critical role for talin-binding by Shigella IpaA VBS3 and possibly talin VBSs in the regulation of adhesion structures.
Structured professional development for academic developers: A collaborative approach

ABSTRACT This paper shares the experience of a group of academic developers’ engagement in collaboratively working towards the completion of an online open-access professional development (PD) course designed to support higher education teachers to engage with a new professional development framework. Committee members of the Educational Developers in Ireland Network set out to complete the course as a demonstration of their commitment to their own PD and to experience the process with a view to becoming facilitators of the course. An auto-ethnographic approach was used to capture this experience, and findings demonstrate an inspiring alternative to PD that supports academic developers in the quest to legitimise and prioritise their own PD in the context of highly pressurised roles.
Quality peach produced in fertilizer doses of nitrogen and green pruning

The increasing consumer demand for fruit quality justifies the development of researches that combine orchards management and consumers’ perception of the quality of the product. The aim of this study was to evaluate the effect of nitrogen fertilization combined with green pruning intensity on fruit quality of ‘Chimarrita’ from high density peach trees during three consecutive harvest seasons. For this purpose, urea composed of different nitrogen rates (0, 40, 80, 120, 160, 200 and 240 kg.ha-1.year-1) was applied, under two intensities of green pruning (annual – once per season; or continuous – four times SOIL AND PLANT NUTRITION Article Quality peach produced in fertilizer doses of nitrogen and green pruning Marcos Antonio Dolinski1*, Jessica Welinski de Oliveira Dangelo1, Francine Lorena Cuquel1, Antonio Carlos Vargas Motta2, Louise Larissa May De Mio3 1.Universidade Federal do Paraná Departamento de Fitotecnia e Fitossanitarismo Curitiba (PR), Brazil. 2.Universidade Federal do Paraná Departamento de Solos e Engenharia Agrícola Curitiba (PR), Brazil. 3.Universidade Federal do Paraná Programa de Pós-Graduação em Agronomia Produção Vegetal Curitiba (PR), Brazil. *Corresponding author: dolinskiagro@gmail.com Received: Jul. 27, 2016 – Accepted: Feb. 6, 2017 per season) in a factorial scheme (7 × 2). Fruits have been subjected to physical, chemical and sensorial analysis, made by 60 non-trained evaluators in each of the harvest seasons. The results showed that the cumulative effect of applying N in the third harvest season improved SS attributes, SS/TA ratio and fruit skin color to the dose of N of 148 kg.ha-1.year-1. There is no difference between green pruning intensity and peach fruit quality.
Work/Family Conflict of More Importance than Psychosocial Working Conditions and Family Conditions for Mental Wellbeing

Studies have indicated the importance of family life and psychosocial working conditions for mental wellbeing. More recently, studies have highlighted that a good balance between work and family is crucial for good mental wellbeing. However, few studies compare the relative importance of these factors for mental wellbeing. The main aim of this study was to analyse the relative importance of psychosocial working conditions, family conditions and work/family conflict for mental wellbeing. The analyses are based on a Swedish data set, including questions regarding working life, family life and mental wellbeing. A total of 12,461 married/cohabiting individuals employed in Swedish organisations were included in the study. Results show that psychosocial working conditions, family conditions and work/family conflict all were related to mental wellbeing. In the final regression model, the strongest correlation was found between mental wellbeing and the variables work/family conflict, satisfaction with private life and partner relationship, with work/family conflict appearing to be of greatest importance. These findings highlight the necessity of including measurements of work/family conflict when studying the importance of work and family conditions for individual mental wellbeing. For workplace health promotion and improvement, it may be beneficial to consider not only psychosocial working conditions, but also family conditions, and particularly work/life conflict.
Does the typeface on album cover influence expectations and perception of music?

CD and digital album covers are part of the music purchase/consumption experience, yet very little is known about how album cover design influences people’s expectations concerning, and their perception of, music. This paper explores the effect of the typeface curvilinearity of album cover design on people’s expectations and perception of music. Typeface curvilinearity has been shown to influence expectations across other sensory modalities, such as taste (gustation). Across three studies, we demonstrate how angular versus rounded typeface can impact expectations concerning how the music will sound. We also demonstrate how angular and rounded typefaces influence emotion ratings of actual music samples. In Experiment 1, typeface curvilinearity influenced people’s expectations of music, with participants expecting the music to sound more angular, masculine, fast, rough, happy, evil, violent, exciting, and active when the typeface on the faux CD album cover was angular compared to when it was round. Conversely, participants expected the music to sound more round, feminine, slow, smooth, sad, good, gentle, calm, and passive when the typeface was round than when it was angular. Experiment 2 demonstrated that typeface curvilinearity influenced people’s ratings of emotional valence but not arousal in neutral music (i.e., music that is considered neither round nor angular). Specifically, participants evaluated the music as sounding more pleasant when the CD cover featured round typeface. Finally, in Experiment 3, we did not find evidence that CD album cover typeface influences people’s perception of arousal or valance of music when the music itself is rated as sounding highly round or angular. These results will be of interest to designers and marketing experts when creating CD covers, logos, posters, and lyric videos.
Frequency-specific transcranial neuromodulation of oscillatory alpha power alters and predicts human visuospatial attention performance

Unilateral transcranial alternating current stimulation (tACS) at alpha frequency modulates the locus of spatial attention. However, the neural mechanisms by which tACS influences spatial attention remain poorly understood. Here, we applied high-definition tACS at the individual alpha frequency (IAF), two control frequencies (IAF+/-2Hz) and sham to the left posterior parietal cortex and measured its effects on visuospatial attention performance as well as alpha power (using electroencephalography, EEG). Our results revealed a leftward lateralization of alpha power relative to sham. At a high value of leftward alpha lateralization, we also observed a leftward attention bias, which differed from sham. Moreover, the magnitude of the alpha lateralization effect predicted the attention bias. These effects occurred for tACS at IAF but not for the control frequencies. This suggests that tACS operates through oscillatory interactions with ongoing brain rhythms in line with the synchronization theory. Our results also highlight the importance of personalized stimulation protocols, especially in potential clinical settings.
Developmental Trajectories in the Understanding of Everyday Uncertainty Terms

Dealing with uncertainty and different degrees of frequency and probability is critical in many everyday activities. However, relevant information does not always come in the form of numerical estimates or direct experiences, but is instead obtained through qualitative, rather vague verbal terms (e.g., "the virus often causes coughing" or "the train is likely to be delayed"). Investigating how people interpret and utilize different natural language expressions of frequency and probability is therefore crucial to understand reasoning and behavior in real-world situations. While there is considerable work exploring how adults understand everyday uncertainty phrases, very little is known about how children interpret them and how their understanding develops with age. We take a developmental and computational perspective to address this issue and examine how 4- to 14-year-old children and adults interpret different terms. Each participant provided numerical estimates for 14 expressions, comprising both frequency and probability phrases. In total we obtained 2856 quantitative judgments, including 2240 judgments from children. Our findings demonstrate that adult-like intuitions about the interpretation of everyday uncertainty terms emerge fairly early in development, with the quantitative estimates of children converging to those of adults from around 9 years on. We also demonstrate how the vagueness of verbal terms can be represented through probability distributions, which provides additional leverage for tracking developmental shifts through cognitive modeling techniques. Taken together, our findings provide key insights into the developmental trajectories underlying the understanding of everyday uncertainty terms, and open up novel methodological pathways to formally model the vagueness of probability and frequency phrases, which are abundant in our everyday life and activities.
l-Ascorbic Acid and Thymoquinone Dual-Loaded Palmitoyl-Chitosan Nanoparticles: Improved Preparation Method, Encapsulation and Release Efficiency

Encapsulation of dual compounds of different characters (hydrophilic and hydrophobic) in single nanoparticles carrier could reach the site of action more accurately with the synergistic effect but it is less investigated. In our previous findings, combined-compounds encapsulation and delivery from chitosan nanoparticles were impaired by the hydrophilicity of chitosan. Therefore, hydrophobic modification on chitosan with palmitic acid was conducted in this study to provide an amphiphilic environment for better encapsulation of antioxidants; hydrophobic thymoquinone (TQ) and hydrophilic l-ascorbic acid (LAA). Palmitoyl chitosan nanoparticles (PCNPs) co-loaded with TQ and LAA (PCNP-TQ-LAA) were synthesized via the ionic gelation method. Few characterizations were conducted involving nanosizer, Fourier-transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM). UV–VIS spectrophotometry was used to analyze the encapsulation and release efficiency of the compounds in PCNPs. Successfully modified PCNP-TQ-LAA had an average particle size of 247.7 ± 24.0 nm, polydispersity index (PDI) of 0.348 ± 0.043 and zeta potential of 19.60 ± 1.27 mV. Encapsulation efficiency of TQ and LAA in PCNP-TQ-LAA increased to 64.9 ± 5.3% and 90.0 ± 0%, respectively. TQ and LAA in PCNP-TQ-LAA system showed zero-order release kinetics, with a release percentage of 97.5% and 36.1%, respectively. Improved preparation method, encapsulation and release efficiency in this study are anticipated to be beneficial for polymeric nanocarrier development.

Differences in the cnidomes and toxicities of the oral arms of two commercially harvested rhizostome jellyfish species in Thailand

Abstract In Thailand, two species of rhizostome jellyfish, Rhopilema hispidum and Lobonemoides robustus, are commercially harvested. The cnidomes, nematocyst size and toxicities were compared between these species. Rhopilema hispidum and L. robustus each had four types of nematocysts on their oral arms. For R. hispidum, these nematocyst types included two types of isorhiza and two types of rhopaloid, while in L. robustus, there were three types of isorhiza and one type of rhopaloid. For R. hispidum, tubule lengths of the largest nematocyst type (large round isorhiza; mean ± SD = 313.8 ± 62.2 μm) were significantly longer than those of L. robustus (large ellipsoid rhopaloid; 162.1 ± 38.5 μm). Using the freshwater shrimp, Palaemon paucidens, in a bioassay, we determined that the lethal nematocyst concentrations for R. hispidum and L. robustus were 5705.3 ± 1118.1 and 3408.3 ± 1032.9 unit g−1 wet weight, respectively, and that these concentrations were significantly higher in the former than in the latter.
