Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex
Authors: Dannenberg Holger , Lazaro Hallie , Nambiar Pranav , Hoyland Alec , Hasselmo Michael E. 
Published: April 2020

ABSTRACTNeuronal representations of spatial location and movement speed in the medial entorhinal cortex during the “active” theta state of the brain are important for memory-guided navigation and rely on visual inputs. However, little is known about how visual inputs change neural dynamics as a function of running speed and time. By manipulating visual inputs in mice, we demonstrate that changes in spatial stability of grid cell firing as a function of time correlate with changes in a proposed speed signal by local field potential theta frequency. In contrast, visual inputs do not affect the speed modulation of firing rates. Moreover, we provide evidence that sensory inputs other than visual inputs can support grid cell firing, though less accurately, in complete darkness. Finally, changes in spatial accuracy of grid cell firing on a 10-s time scale suggest that grid cell firing is a function of velocity signals integrated over past time.
Effect of the use of dry breadcrumb in meatball production on the formation of heterocyclic aromatic amines
Authors: Korkmaz Ahmet , Oz Fatih 
Published: April 2020

PurposeHeterocyclic aromatic amines are mutagenic and/or carcinogenic compounds formed during cooking of meat. Therefore, the formation levels of them should be reduced. For this aim, the purpose of the present study was to determine the effect of dry breadcrumb in meatball production on the formation of heterocyclic aromatic amines. In addition, the effect of dry breadcrumb on some quality parameters of the meatballs was also investigated.Design/methodology/approachMeatball dough with 15 percent fat was divided into four parts, where one group was selected as the control group (without dry breadcrumb). In the other three groups, dry breadcrumb was added in various ratios of 5 percent, 10 percent and 15 percent (w/w). Then, meatball dough was stored at 4 °C for 3 h and shaped into meatballs with a metal shaping device (7 × 1 cm). For some of the quality parameters, water, pH, cooking loss and TBARS analyses were done in the samples. Heterocyclic aromatic amine analysis was done in only cooked samples according to solid phase extraction.FindingsThe use of dry breadcrumb in meatball production decreased water content and cooking loss. As cooking temperature increased, water contents and cooking loss of meatball decreased. PhIP, AαC and MeAαC were not detected in any of the samples analyzed. As cooking temperature increased, total amount of HCAs increased and ranged between 0.05 and 0.51 ng/g. While the use of dry breadcrumb in the meatball production increased IQ content of the meatballs, the use of 5 percent dry breadcrumb caused a decrease in the total HAA content (28.57–66.67 percent) for all cooking temperatures.Originality/valueMany research studies including our study in the literature were conducted on formation and reduction of HAAs in meat and meat products. However, although dry breadcrumb is frequently used both in domestic and commercial meatball formulations; to the best of our knowledge, effect of using dry breadcrumb in meatball production on HAAs formation has not been investigated in the literature. Therefore, in the present study, the effects of the use of dry breadcrumb in meatball production on some quality parameters and formation of HAAs in meatballs cooked at 150 °C, 200 °C and 250 °C were determined.
Economic sustainability of wine tourism services and direct sales performance – emergent profiles from Italy
Authors: Smyczek Sławomir , Festa Giuseppe , Rossi Matteo , Monge Filippo 
Published: April 2020

PurposeDirect sales at the winery constitute one of the most used indicators for evaluating the success of a wine tourism experience. In this respect, service performance at the winery can have some influence on sales, which assumes that there is a direct link between the service level intensity of the wine tourism offer and the intensity level of direct sales at the winery; thus proposing that the global sustainability of the economic performance of the winery would increase if the wine tourism experience was supported by intense wine tourism services.Design/methodology/approachA descriptive statistical investigation was conducted on a sample of 35 Italian wineries, giving evidence on the adoption of different service categories as part of the wineries' wine tourism offers. From these results, an inferential statistical analysis was conducted to detect the existence of a direct link between wine tourism services and direct sales at the winery.FindingsBased on the current investigation, even though it was of an exploratory nature, the evidence does not in general support a direct link between the service level intensity of the wine tourism offer and the level of intensity of direct sales at the winery. Instead, some evidence points to a potential direct link between logistics services and direct sales. Unfortunately, some evidence emerged regarding the lack of availability of wine tourism services for disabled persons.Originality/valueWine tourism is a relevant success factor for the wine business. Its influence affects not only the wineries' reputation through word-of-mouth, most of all on the social networks but also their image and most importantly their direct sales. Frequently, in fact, wine tourism performance can be evaluated by direct sales performance. As a result of the current investigation, however, it is likely that the intensity level of direct sales at the winery is not the most correct indicator for evaluating the success of a wine tourism experience with high levels of service, especially when considering overall sustainability.

Published: April 2020

AbstractSeed germination is a key part of plants' life cycle and is mostly affected by the genetic background, the environmental conditions experienced by the mother plant and the seedbed conditions. The germination response to light is essential to optimize germination and seedling establishment in space and time. In addition, the germination response to light is a trait often related to the response of the seeds to their position in the soil (uncovered/buried). Here, we studied the germination response to light of four key tree species of the Yungas forest (Anadenanthera colubrina, Enterolobium contortisiliquum, Jacaranda mimosifolia and Handroanthus impetiginosus) sampled along an elevational and environmental gradient with contrasting vegetation cover and disturbance. Relative light germination (RLG) and mean germination time (MGT) were determined. Final germination was tested under cycles of light (8 h) and darkness (16 h) versus complete darkness (24 h) and elevation, and MGT was tested as a function of elevation of the provenance. The RLG increased from smaller to larger‐seeded species. The MGT of three of the studied species was affected by the elevation of the provenance. Complete darkness negatively affected final germination, while two species exhibited a significant interaction between the provenance and light. The variable germination responses to light along the elevational gradient highlights the influence of the environment on germination as a key factor that should be considered for forest management, conservation and restoration projects.
Responses of physiological groups of tropical heterotrophic bacteria to temperature and dissolved organic matter additions: food matters more than warming
Authors: Morán Xosé Anxelu G. , Baltar Federico , Carreira Cátia , Lønborg Christian 
Published: April 2020

SummaryCompared to higher latitudes, tropical heterotrophic bacteria may be less responsive to warming because of strong bottom‐up control. In order to separate both drivers, we determined the growth responses of bacterial physiological groups to temperature after adding dissolved organic matter (DOM) from mangroves, seagrasses and glucose to natural seawater from the Great Barrier Reef. Low (LNA) and high (HNA) nucleic acid content, membrane‐intact (Live) and membrane‐damaged (Dead) plus actively respiring (CTC+) cells were monitored for 4 days. Specific growth rates of the whole community were significantly higher (1.9 day‐1) in the mangrove treatment relative to the rest (0.2–0.4 day‐1) at in situ temperature and their temperature dependence, estimated as activation energy, was also consistently higher. Strong bottom‐up control was suggested in the other treatments. Cell size depended more on DOM than temperature. Mangrove DOM resulted in significantly higher contributions of Live, HNA and CTC+ cells to total abundance, while the seagrass leachate reduced Live cells below 50%. Warming significantly decreased Live and CTC+ cells contributions in most treatments. Our results suggest that only in the presence of highly labile compounds, such as mangroves DOM, can we anticipate increases in heterotrophic bacteria biomass in response to warming in tropical regions.

Published: April 2020

AbstractObjectiveTo compare hospital‐community partnerships among safety‐net hospitals relative to non–safety‐net hospitals, and explore whether hospital‐community partnerships are associated with reductions in readmission rates.Data SourcesData from four nationwide hospital‐level datasets for 2015‐2016, including American Hospital Association (AHA) annual survey, Hospital Inpatient Prospective Payment System (IPPS) data, CMS Hospital Compare, and County Health Rankings National (CHRN) data.Study DesignWe first examined how safety‐net hospitals partner with nine different community providers, and how the overall and individual partnership patterns differ from those in non–safety‐net hospitals. We then explored their association with 30‐day readmission rates by diagnosis and hospital wide.Data Collection/Extraction MethodsWe included 1979 hospitals across 50 US states.Principal FindingsSafety‐net hospitals were more engaged in hospital‐community partnerships, especially with local public health, local governments, social services, nonprofits, and insurance companies, relative to their non–safety‐net peers. However, we found that such partnerships were not significantly related to reductions in readmission rates. The findings indicated that merely partnering with various community organizations may not be associated with readmission rate reduction.ConclusionsBefore promoting partnerships with various community organizations for its own sake, further prospective, longitudinal, and evidence‐based guidance derived from the study of hospital‐community partnerships is needed to make meaningful recommendations aimed at readmission rate reduction in safety‐net hospitals.

Authors: Machado Nardi Vinicius Antonio , Auler Daniel Pedro , Teixeira Rafael 
Published: April 2020

AbstractThis paper aimed to revisit the literature on food safety in global supply chains and analyze the evolution and contemporary challenges in this research field. It conducted a systematic literature review in two steps based on a selection of 178 articles. It analyzed safety in food supply chains using the Six T's Framework to evaluate food safety management. In the supply chain literature, traceability was the most studied element of the original framework. The research identified studies that have incorporated the topics of “tactics” and “targets” in their analysis of safety in supply chains. This article presented an expanded framework, a tool for categorizing research, and areas for advancement in the identification of quality indicators in global food chains for the current research agenda. The paper contributed theoretically to the discussion of safety elements in food supply chains and incorporated new elements into the originally conceived framework. Thus, it helped to delineate the research field and opened up an agenda for future research.
Spore inactivation on solid surfaces by vaporized hydrogen peroxide—Influence of carrier material surface properties
Authors: Eschlbeck Elisabeth , Seeburger Christina , Kulozik Ulrich 
Published: April 2020

AbstractThe aim of this study was to investigate the influence of surface hydrophobicity and roughness of carrier materials on the inactivation of bacterial spores with gaseous hydrogen peroxide whereas condensate formation is prevented. Spores of Bacillus subtilis and Bacillus atrophaeus were applied either as single spore culture or as a mixed spore population to simulate natural contamination with microorganisms of different characteristics. Inactivation with gaseous hydrogen peroxide was carried out at 5200 ppm hydrogen peroxide without condensate formation. The inactivation results of B. subtilis and B. atrophaeus spores on carrier materials with varying surface hydrophobicity differed significantly. However, inactivation of the mixed spore populations resulted in similar resistance compared to the single spore batches.The results of this study indicate that surface hydrophobicity most probably has an impact on the inactivation with gaseous hydrogen peroxide whereas surface roughness only plays a minor role.

Published: April 2020

AbstractThe volume of water is a key variable affecting texture and flavor attributes of cooked rice with a significant influence on consumer preference. The aim of this study was to determine the attributes driving consumer preference for rice cooked with different water‐to‐rice ratios. Descriptive analysis (DA) methodology was employed to profile aromatic white Jasmine rice and a consumer study was run to determine preference for water‐to‐rice ratios. A DA panel (n = 12) evaluated ten aroma, four taste and flavor, three texture, and six appearance attributes for aromatic white Jasmine rice cooked with four water‐to‐rice ratios (1.125:1, 1.5:1, 1.875:1, and 2.25:1). Rice consumers (n = 117) evaluated preferences of the same aromatic white Jasmine rice cooked with the aforementioned water‐to‐rice ratios. DA results revealed floral aroma, firmness, chewiness, coarseness, stickiness/cohesiveness, and fluffiness were significantly influenced by an increasing water‐to‐rice ratio. There was no significant effect of water‐to‐rice ratios on consumer preferences (χ2 (3, 117) = 1.17; P = 0.76). Consumers were grouped into three clusters with similar preference patterns using agglomerative hierarchical clustering. External preference mapping techniques run on each consumer cluster determined the water‐to‐rice ratios 1.125:1 and 1.875:1 as having the largest appeal to heavy consumers of rice, split by preferences for fluffy or sticky cooked rice. The water‐to‐rice ratio 1.5:1 was not dominated by any single attribute or group of attributes, appealing to less frequent rice consumers. Therefore, the water‐to‐rice ratios 1.125:1, 1.5:1, and 1.875:1 should satisfy the broadest groups of Australian rice consumers.Practical ApplicationRice, a high volume commodity can be cooked using a variety of methods and volumes of water. The findings of this research will help manufacturers market water‐to‐rice ratios, assisting consumers in identifying cooked rice for which they have a preference.

Published: April 2020

AbstractTiger frog (Rana tigrina) meat is extremely perishable. This study investigated the antimicrobial efficacy of chlorine dioxide (ClO2) on frog meat, optimized the formulation of a phosphate‐based enhancement solution by response surface methodology (RSM), and determined the quality parameters (i.e., total aerobic counts [TAC], pH, drip loss, cooking loss, color measurements, shear force, total volatile basic nitrogen [TVB‐N], and thiobarbituric acid–reactive substances [TBARS]) of refrigerated frog meat pretreated with ClO2 and the optimized blend of phosphates. Treatments of frog meat with 35 and 70 ppm ClO2 for 3, 5, and 10 min achieved a 0.7‐, 0.9‐ and 0.9‐, and 0.8‐, 1.4‐ and 1.6‐log CFU/g reduction of TAC, respectively, indicating the antimicrobial efficacy of ClO2 was concentration‐ and time‐dependent with such that higher concentrations and/or longer exposure time achieved greater bacterial reductions. The concentrations of the phosphates, including sodium tripolyphosphate (STPP), sodium pyrophosphate (SPP), and sodium hexametaphosphate (SHMP), were optimized as the formula of 0.3% STPP and 0.45% SPP obtaining the highest water retention of the frog meat. After washed with 70 ppm ClO2 for 10 min and subsequently soaked with 0.3% STPP and 0.45% SPP for 30 min, the frog meat stored at 4 °C shown significantly (P < 0.05) lower TAC (<4.4 log CFU/g) and higher water holding capacity during the whole storage of 12 days, compared to the control. Results indicated that the two‐step process may be applicable to slow down deterioration and maintain quality frog meat during refrigeration.Practical ApplicationThis research provides a means to slow down deterioration, maintain quality frog meat, and improve stability during refrigeration. Refrigerated frog meat products, which are preferred by consumers with juicier and more tender texture compared to the frozen‐thawed meat, could be developed by the frog industry based on the data from this study.
