Second, the company is expected to be able to manage the knowledge owned by the company so that the knowledge it has can increase the creation of company innovation it provides a competitive advantage for the company.
Originality/value –The contribution of this research is that the results of this study can be used as empirical evidence for banking companies of the importance of the role of IC, innovation, and KM in improving company performance by constantly creating the company's competitive advantage.
Can Citizen Science in the Humanities and Social Sciences Deliver on the Sustainability Goals?
Authors: Henke Justus
Published: July 2022

Both the sustainability discourse and the debate on citizen science are strongly focused on the natural and technical sciences. Yet, numerous participatory research activities can be identified in the social sciences and humanities that address sustainability issues of various kinds. These have hardly been studied so far, and their contribution to addressing sustainability challenges is poorly known. The study investigates which sustainability topics are taken up by citizen science in the humanities and social sciences, which factors influence the choice of topics, and its implications. For this purpose, the concept of Citizen Social Science (CSS) is taken up and sustainability is operationalized via the Sustainable Development Goals (SDG) and its specific Targets. Based on a collection of CSS activities in Germany, the addressed sustainability topics are identified accordingly. This is followed by an analysis of how these patterns depend on key characteristics of the CSS projects. The findings indicate a focus on three SDGs related to education, sustainable cities and partnerships for the Goals, while at the same time the project consortia are very heterogeneous. CSS shows particular strengths here through its multi-stakeholder approach. Going forward, the linking of Citizen Science with the SDGs requires further formalization so that its transformative effects can be incorporated into SDG monitoring and the scientific institutions need additional incentives to participate in CSS.

We determined the levels of neutralizing antibodies against the SARS-CoV-2 ancestral strain, Delta and Omicron variants of concern (VOCs) in 125 healthcare workers, who received Coro-naVac as their primary vaccination and later received either a single ChAdOx1 or a combination of two consecutive boosters using either two ChAdOx1 doses or a ChAdOx1 or BNT162b2 as the primary and second boosters, respectively, or 2 doses of BNT162b2. The titers 12 weeks after primary vaccination were inadequate to neutralize the all strains. After a single ChAdOx1 boost-er, the levels of neutralization at Day 30 varied significantly, only a small proportion of partici-pants developing neutralizing titers against Omicron at Day 7 and 30. The two doses of ChA-dOx1 as the booster induced lowest activity. A combination ChAdOx1 and BNT162b2 induced greater neutralization than by two doses of ChAdOx1. Two doses of BNT162b2 as the booster had the maximal activity against Omicron VOC.

Nanocomposites and Semiconductor Devices Based on Recycled Radioactive Waste
Authors: Kizka Valeriy
Published: July 2022

The article provides an overview of nanocomposites and microelectronic elements used in space electronics and radiation control systems of nuclear reactors. Only those nanocomposites and microelectronic elements are taken into account that improve their characteristics in radiation fields or remain indifferent when exposed to ionizing radiation. Considering the chemical composition of the materials of these nanocomposites and microelectronic elements, it is analyzed from which radioactive materials (RM) obtained by recycling radioactive waste (RW) such composites and microelectronic parts can be made. Thus, an alternative way of radioactive waste disposal is proposed, when these wastes are used in the form of microelectronic elements designed to operate under conditions of cosmic radiation.

Published: July 2022

High population growth in a region commonly pushes the government to fast provide public facilities in order to fullfil the public needs. Along with it, one of the challenges that faced by the urban center of Pattallassang Distric in Gowa Regency is rapid land convertion due to high land demand to provide public facilities. This urban area is highly populated and has intense activities because not only it functions as center of government but also as a Special Economic Zone (KEK) of the region. The aim of this research is to evaluate the landuse realization in Gowa Region, between what is found in reality with what has been planned in regional spatial plan (RTRW), as well as to identify the contributing factors behind the discrepancies. This research was conducted from September 2019 to February 2020 (6 months). The data and information were collected through literature study related to land suitability evaluation methods, influencing factors, and field survey. The research used method of spatial analysis using overlay techniques with the help of software ArcGIS 10.1, scoring analysis to define the suitability value, and qualitative descriptive analysis to determine factors that contribute to the discrepancy between existing landuse and the RTRW document. The results showed that among the many landuse discrepancies, the residential landuse has the lowest value of suitability value of 24%. Economical and environmental factors may play important roles in this discrepancy.

Objectives. To describe which industries have the highest burden of COVID-19 outbreaks in California.

Methods. We assigned US census industry codes to COVID-19 outbreaks reported to the California Department of Public Health (CDPH) from January 1, 2020, to August 31, 2021, and determined numbers of outbreaks, numbers of outbreak-associated cases, and outbreak incidence levels by industry. We determined characteristics of outbreak-associated cases using individual case data linked to COVID-19 outbreaks.

Results. Local health departments reported 19 893 COVID-19 outbreaks and 300 379 outbreak-associated cases to CDPH. The most outbreaks (47.8%) and outbreak-associated cases (54.8%) occurred in the health care and social assistance sector, where outbreak incidence levels were highest in skilled nursing facilities and residential care facilities (1306 and 544 outbreaks per 1000 establishments, respectively). High proportions of outbreaks also occurred in the retail trade (8.6%) and manufacturing (7.9%) sectors. Demographics of outbreak-associated cases varied across industries.

Conclusions. Certain California industries, particularly in the health care, manufacturing, and retail sectors, have experienced a high burden of COVID-19 outbreaks during the pandemic.

Public Health Implications. Tracking COVID-19 outbreaks by industry may help target prevention efforts, including workforce vaccination. (Am J Public Health. 2022;112(8):1180–1190. https://doi.org/10.2105/AJPH.2022.306862 )

Published: July 2022

Objectives. To understand the frequency, magnitude, geography, and characteristics of tuberculosis outbreaks in US state prisons.

Methods. Using data from the National Tuberculosis Surveillance System, we identified all cases of tuberculosis during 2011 to 2019 that were reported as occurring among individuals incarcerated in a state prison at the time of diagnosis. We used whole-genome sequencing to define 3 or more cases within 2 single nucleotide polymorphisms within 3 years as clustered; we classified clusters with 6 or more cases during a 3-year period as tuberculosis outbreaks.

Results. During 2011 to 2019, 566 tuberculosis cases occurred in 41 state prison systems (a median of 3 cases per state). A total of 19 tuberculosis genotype clusters comprising 134 cases were identified in 6 state prison systems; these clusters included a subset of 5 outbreaks in 2 states. Two Alabama outbreaks during 2011 to 2017 totaled 20 cases; 3 Texas outbreaks during 2014 to 2019 totaled 51 cases.

Conclusions. Only Alabama and Texas reported outbreaks during the 9-year period; only Texas state prisons had ongoing transmission in 2019. Effective interventions are needed to stop tuberculosis outbreaks in Texas state prisons. (Am J Public Health. 2022;112(8):1170–1179. https://doi.org/10.2105/AJPH.2022.306864 )

Authors: Seymour Jane W. , Thompson Terri-Ann , Milechin Dennis , Wise Lauren A. , Rudolph Abby E.
Published: July 2022

Objectives. To quantify the impact of telemedicine for medication abortion (TMAB) expansion or ban removal on abortion accessibility.

Methods. We included 1091 facilities from the 2018 Advancing New Standards in Reproductive Health facility database and Planned Parenthood Web site, among which 241 did not offer abortion as sites for TMAB expansion. Accessibility was defined as the proportion of reproductive-aged women living within a 30-, 60-, or 90-minute drive time from an abortion-providing facility. We calculated accessibility differences between 3 scenarios: (1) facilities offering abortion in 2018 (reference), (2) the reference scenario in addition to all facilities in states without TMAB bans (TMAB expansion), and (3) all facilities (TMAB ban removal). We also stratified by state and urban–rural status.

Results. In 2018, 65%, 81%, and 89% of women lived within a 30-, 60-, or 90-minute drive time from an abortion-providing facility, respectively. Expansion and ban removal expanded abortion accessibility relative to the current accessibility scenario (range: 1.25–5.66 percentage points). Women in rural blocks experienced greater increases in accessibility than those in urban blocks.

Conclusions. TMAB program and policy changes could expand abortion accessibility to an additional 3.5 million reproductive-aged women.

Public Health Implications. Our findings can inform where to invest resources to improve abortion accessibility. (Am J Public Health. 2022;112(8):1202–1211. https://doi.org/10.2105/AJPH.2022.306876 )

Published: July 2022

In June 2020, Massachusetts implemented a first in the nation statewide law that restricts sales of menthol and other flavored tobacco. Since implementation, sales data indicate high retailer compliance. Drastic decreases were seen in sales of all flavored tobacco. Most neighboring states did not see increases in overall tobacco sales, although New Hampshire saw an initial increase in menthol sales, which was not sustained. We found that menthol restrictions are effective and that federal-level legislation is important, as some cross-border sales highlight.

Xylazine and Overdoses: Trends, Concerns, and Recommendations
Authors: Alexander Ryan S. , Canver Bethany R. , Sue Kimberly L. , Morford Kenneth L.
Published: July 2022

Xylazine is a nonopioid veterinary anesthetic and sedative that is increasingly detected in the illicit drug supply in the United States. Data indicate a striking prevalence of xylazine among opioid-involved overdose deaths.

The emergence of xylazine in the illicit drug supply poses many unknowns and potential risks for people who use drugs. The public health system needs to respond by increasing testing to determine the prevalence of xylazine, identifying its potential toxicity at various exposure levels, and taking mitigating action to prevent harms.

Currently, there is little testing capable of identifying xylazine in drug supplies, which limits the possibility of public health intervention, implementation of harm reduction strategies, or development of novel treatment strategies.

Published: July 2022

Biosorption isotherms define the relationship between biosorption capacity of the biosorbent and the equilibrium concentration of the ions in solution, at a constant temperature. Experiments are routinely performed under near-equilibrium because it is impossible to determine the exact time at which equilibrium was attained. A novel attempt to study multi-ion biosorption in non-equilibrium conditions has been made, based on the Probability Isotherm theory. Materials and Methods: Probability Isotherm theory was examined with cucumber and kiwifruit peel beads which are reported to be efficient biosorbents. The peels were incubated in a cocktail of seven ions (As, Cd, Cr, Cu, Hg, Pb and Ni) at the same initial concentration (0.1- 15 mgL-1) and four different temperatures (25-55°C). Non-equilibrium biosorption data were modeled by Langmuir isotherm model. Data were analyzed using a one-way ANOVA coupled with a Bonferroni post-hoc test on GraphPad Prism 8 software. Cd and Ni ions showed the most well-defined trends with Langmuir isotherm model. The binding of ions was physico-chemical with simultaneously occurring physisorption and tchemisorption reactions. Conclusions: Probability Isotherm theory can be applied to multi-ion biosorption in non-equilibrium conditions. The behavior of each ion is unique and no two biosorption systems are alike.
Correlative conformity or subtle unconformity? The distal expression of a sequence boundary in the Upper Cretaceous Mancos Shale, Henry Mountains Region, Utah, U.S.A.
Authors: Li Zhiyang , Schieber Juergen
Published: July 2022

In models of siliciclastic sequence stratigraphy, the sequence boundary in distal marine environments, where the strata are mudstone dominated, is usually considered a correlative conformity—the seaward extension of a subaerial unconformity. Despite its wide usage in the literature, objective recognition criteria of a correlative conformity remain lacking, largely due to the limited number of case studies directly examining the characteristics of sequence boundaries in offshore mudstone-dominated environments. This study focuses on the mudstone-dominated transitional interval between the Tununk Shale Member and the Ferron Sandstone Member of the Mancos Shale Formation exposed in south-central Utah to extend our understanding of the characteristics of a sequence boundary developed in the distal shelf environment of a ramp setting. An integrated sedimentologic, petrographic, and sequence stratigraphic analysis was conducted to characterize the sequence boundary that separates the Tununk from the Ferron depositional system (hereafter referred to as the T-F sequence boundary) and its lateral along-depositional-strike variability.

Although manifest as a mudstone-on-mudstone contact, the T-F sequence boundary in all three measured sections is a subtle unconformity, characterized by erosional truncation below and onlap above, and marks a distinct basinward shift in facies association. The T-F sequence boundary also marks the change from the Tununk offshore mud-belt system to the Ferron Notom delta system, and therefore represents a surface that divides two genetically different depositional systems. Based on two distinct marker beds that bracket the T-F sequence boundary, the T-F sequence boundary can be traced across the study area with confidence. The lateral variability in the characteristics of the T-F sequence boundary along depositional strike indicates that it was produced by an allogenic base-level fall.

Offshore shelfal mudstone strata may contain a significantly higher incidence of subtle unconformities analogous to the T-F sequence boundary than currently appreciated. Careful sedimentologic and petrographic analyses, combined with lateral correlations constrained by reliable chronostratigraphic marker beds, are essential for identifying subtle unconformities in shelf mudstone successions. The accurate recognition of subtle unconformities in mudstone strata is critical to apply the sequence stratigraphic approach appropriately to distal shelf environments, as well as to better constrain the timing and cause (allogenic vs. autogenic) of relative changes of sea level recorded in these rocks.
Association between COVID-19 and Heavy Metal Pollution in Iraqi Cities Determined from Hierarchical Prediction
Authors: Raheem Aram Mohammed
Published: July 2022

This study assesses the relationship between coronavirus (COVID-19) and the spread of various heavy metal contaminants across Iraq. The study collects all confirmed, recovered, and death cases of the COVID-19 virus at its onset in Iraq until May 2, 2020, comparing Iraq with the top three infected countries in the world (the United States Spain, and Italy). In addition, numerous heavy metal contamination in different Iraqi cities have been summarized and associated with the allowable upper and lower worldwide standard limits. Furthermore, the study introduces a hierarchical predictive approach for the relationship between confirmed infected cases and deaths due to the COVID-19 virus and heavy metal contamination in various Iraqi cities. It is concluded that all the studied Iraqi cities have heavy metal contamination for different chemical elements exceeding the allowable standard limits. Extreme contents of copper, nickel, lead, and zinc are concentrated in Al-Qadisiyah, Al-Sulaimaniyah, Erbil, and Baghdad with limits of 160 µg/g, 240.9 µg/g, 378 µg/g, and 1,080 µg/g, respectively. Based on the hierarchical prediction approach, a linear positive relationship between both confirmed cases and deaths due to COVID-19 with different heavy metal contamination was obtained with a maximum coefficient of determination (R2) of 0.97.

Integrating the student perspective: A framework for teaching competences in European higher education
Authors: Hempfling Mathias , Hüther-Pape Lisa
Published: July 2022

Despite increasing interest in and demand for student-centred higher education in Europe, there is limited evidence on which competences teachers need in such a paradigm. In particular, the student perspective – while inherently crucial to student-centred higher education – has been largely neglected in the development of teaching competence frameworks. Addressing this gap, we systematically investigated students’ importance ratings of teaching competences. We developed the European Teaching Competence Student Survey (ETCSS) based on Gilis, Clement, Laga and Pauwels’s (2008) competence profile for student-centred higher education that was established with teachers. Using the ETCSS, we found that students across Europe (six countries, eight higher education institutions, N = 242) endorse the teaching competences previously identified with teachers. Based on a mixed-methods approach (exploratory factor analysis and qualitative analysis of open responses), we propose a student-centred framework for teaching competence in higher education comprising 41 indicators across six competence areas: (1) facilitate learning, promote deep knowledge and critical application, (2) continuous improvement in partnership with students, (3) contextualise learning sharing passion and expertise, (4) awareness and empathy, fostering diversity, inclusivity and non-discriminatory action, (5) proficient and purposeful media use and (6) integrity and professional behaviour. Finally, we discuss theoretical and practical implications of our findings with respect to quality development in higher education.

A novel ball screw driven rigid-flexible coupling stage with active disturbance rejection control to compensate for friction dead zone
Authors: Peng Hao , Wei Shengqiang , Huang Xiaohong , Li Ruiqi , Yang Zhijun
Published: July 2022

The ball screw driven high-speed precision motion stage (the rigid stage for short) usually uses mechanical bearings to achieve high stiffness and fast response. However, the positioning precision of the rigid stage is limited by the friction dead zone due to the high stiffness design. This paper proposes a ball screw driven rigid-flexible coupling (RFC) stage to compensate for the friction dead zone by the flexure hinges. The frequency domain analysis shows that the friction is converted into elastic deformation of the flexure hinges. In addition, an active disturbance rejection control (ADRC) is designed to cancel the flexure hinges vibration and maximize the RFC stage performance. Three comparative experiments aim to verify the effectiveness of the presented mechanical design and control scheme. First, the RFC stage with ADRC shows great consistency (both transient and steady-state) and positioning precision (±0.1 μm) in 5 repeated long stroke point-to-point motion experiments. And then, the RFC stage with ADRC can track the ladder-like step reference with fast transients and ±0.1 μm positioning precision. Finally, in the sinusoidal tracking experiment, the maximum and root mean square (RMS) tracking error of the RFC stage with ADRC are reduced by 88.85% and 43.32%, respectively, compared to the rigid stage with PID.

BackgroundCardiovascular diseases (CVDs), the leading cause of death worldwide, are sensitive to temperature. In light of the reported climate change trends, it is important to understand the burden of CVDs attributable to temperature, both hot and cold. The association between CVDs and temperature is region-specific, with relatively few studies focusing on low-and middle-income countries. This study investigates this association in Puducherry, a coastal district in the Eastern part India for the first time.Methods We analyzed the association between apparent temperature (Tapp) and in-hospital CVD mortalities in Puducherry between 2010 and 2020 using a distributed lag non-linear model to capture the delayed and non-linear trends over a 21-day lag period and identify the optimal temperature range for Puducherry. The results are expressed as the fraction of CVD mortalities attributable to heat and cold, defined as temperatures above or below the optimal temperature. We also performed stratified analyses to explore the associations between Tapp and age-and-sex combined and different types of CVDs.Results We found that the optimal temperature range for Puducherry is between 33⁰C and 35⁰C with respect to CVDs. Both cold and hot non-optimal Tapp were associated with an increased risk of overall in-hospital CVD mortalities, resulting in a U-shaped association curve. Cumulatively, up to 20% of the CVD deaths could be attributable to non-optimal temperatures, with a slightly higher burden attributable to cold (11.2%) than heat (9.1%). We also found that males above 60 years of age were more vulnerable to colder temperature; females above 60 years were more vulnerable to heat while females below 60 years were affected by both heat and cold. Mortality with cerebrovascular accidents was associated more with heat compared to cold, while ischemic heart diseases did not seem to be affected by temperature.Conclusion Both heat and cold contribute to the burden of CVDs attributable to non-optimal temperatures in the tropical Puducherry. Our study also identified the age-and-sex and CVD type differences in temperature attributable CVD mortalities. Further studies from India could identify regional associations, inform our understanding of the health implications of climate change in India and enhance the development of regional and contextual climate-health action-plans.

We investigated the potential correlation between the fluid shear stress and the proliferation of bone prostate cancer cells on the surface of nanoclay-based scaffolds in a perfusion bioreactor. Human mesenchymal stem cells (hMSCs) were seeded on the scaffolds to initiate bone growth. After 23 days, prostate cancer cells (MDAPCa2b) were cultured on top of the osteogenically differentiated hMSCs. The scaffolds were separated into two groups subjected to two distinct conditions: (i) static (no flow); and (ii) dynamic (with flow) conditions to recapitulate bone metastasis of prostate cancer. Based on measured data, Computational Fluid Dynamics (CFD) models were constructed to determine the velocity and shear stress distributions on the scaffold surface. Our experimental results show distinct differences in the growth pattern of hMSCs and MDAPCa2b cells between the static and dynamic conditions. Our computational results further suggest that the dynamic flow leads to drastic change in cell morphology and tumorous distribution. Our work points to a strong correlation between tumor growth and local interstitial flows in bones.

Wetlands are considered key ecosystems because of the greatest number of ecosystem services they provide, but despite their important role these ecosystems are decreasing in size and losing quality. Kakel Huincul lake is located in one of the main wetlands of Argentina. A multi-indicator analysis, including pollen, non-pollen palynomorphs and plant macrofossil remains was performed to reconstruct Kakel Huincul lake environmental history in order to understand Pampean wetlands responses to environmental changes and human impacts during the last 600 years. Results showed that changes in the lake communities before 1880 AD were a result of climatic perturbations (increase/decrease rainfall), and after 1880 AD they were a combination of climatic (increases and decreases of precipitation values) and anthropic forcings (cattle, intensive agriculture and urbanization). Baseline conditions were established at ca. 1870 AD and it was concluded that southeastern Pampa plain has been subjected to human activities (cattle farming and incorporation of agriculture) since then. Eutrophication of the lake occurred during the last 25 years, but this study made it possible to establish that the Pampa wetland has been modified for more than five decades ago.

Heterostructured (HS) material with extraordinary mechanical properties has been regarded as one of the most promising structural materials. In this paper, heterogeneous lamella structure (HLS) Cu laminates composed of surface elongated-grain layer and center equiaxed-grain layer were fabricated via rolling bonding and annealing. In order to study the interface effect on mechanical properties of gradient structured materials，both the laminate metal composite (LMC) and the non-composite laminate (NCL) were fabricated by cold-rolling pretreatment of the center layer (60% reduction) and cold-rolling bonding of the whole blank (67% reduction). Then by controlling the post-annealing regimes, the HLS was obtained and the microstructure of each layer was optimized, and a larger degree of microstructure heterogeneities such as grain size, misorientation angle and grain orientation were obtained, which resulted in obvious mechanical differences. Tensile tests of HLS, surface layer, center layer and NCL specimens reveal that the HLS annealed at 300°C/1h has a significantly higher strength than the center layer and a higher elongation than the surface layer. The HLS have a tensile strength and elongation at fracture of 278.08 MPa and 46.2%, respectively, which shows good balance of strength and plasticity. The main reason for the improved properties is the strengthening or strain hardening generated by the inhomogeneous deformation of the heterogeneous layers in the laminate and the mutual constraint acquired by the distinct layers with strong mechanical differences. The HLS has an interfacial bonding strength of 178.5 MPa, which plays a vital role in the coordinated deformation of heterogeneous layers. The method of obtaining gradients in homogeneous materials proposed in this study provides a new way of thinking and enriches the theoretical basis for the comprehensive performance improvement of traditional metallic materials.

Background: Microalgae CO2 fixation results in the production of biomass rich in high-valuable products, such as fatty acids and carotenoids. Enhanced productivity of valuable compounds can be achieved through the microalgae's ability to capture CO2 efficiently from sources of high CO2 contents but is dependent on the species. Although culture collections of microalgae provide a large variety of defined strains, inadequate understanding of which groups of microalgae and strains' origins from habitat offer high productivity under increased CO2 concentrations hampers exploiting microalgae as a sustainable source in the bioeconomy. Results: Growth under atmospheres of CO2 levels of 5 - 25 % in air was examined for 12 new microalgae isolates from adverse terrestrial environments and 69 strains from the culture collection of algae of Göttingen University (SAG), preselected from about 200 strains for their phylogenetic diversity and high productivity under ambient CO2. Green algae from terrestrial environments, including the new isolates, exhibited enhanced growth up to 25% CO2 atmosphere. In contrast, in unicellular red algae and stramenopile algae, which originated through the endosymbiotic uptake of a red algal cell, growth at CO2 concentrations above 5% was suppressed or ceased. While terrestrial stramenopile algae generally tolerated such CO2 concentrations, their counterparts from marine phytoplankton did not. The tests of four new terrestrial strains in submersed culture revealed enhanced biomass and chlorophyll production under elevated CO2 levels. The 15% CO2 aeration increased their total carotenoid and fatty acid contents, which were further stimulated when combined with starvation in macronutrients, i.e., less with phosphate and significantly more with nitrogen-depleted culture media. Conclusion: Isolates of green algae from terrestrial environments, Chlorophyceae and Trebouxiophyceae, exhibit enhanced productivity of carotenoids and fatty acids under elevated CO2 concentrations. This ability supports the economic and sustainable production of valuable compounds of these microalgae using inexpensive sources of high CO2 concentrations such as industrial exhaust fumes.

Alterations in the gut microbiome, including diet-driven changes, are linked to the rising prevalence of food allergy, yet little is known about how specific gut bacteria incite breakdown of oral tolerance. Here, we show that depriving specific-pathogen-free mice of dietary fiber leads to an increase of the mucolytic bacterium Akkermansia muciniphila, which is associated with a surge in the colonic type 2 immune cells and IgE-coated commensals, and microbiota-mediated gut mucosal barrier dysfunction. These changes manifest into exacerbated sensitization to food allergens, ovalbumin and peanut. To demonstrate the causal role of A. muciniphila, we employed a tractable synthetic human gut microbiota in gnotobiotic mice. The presence of A. muciniphila within the microbiota, combined with fiber deprivation, resulted in stronger anti-commensal IgE coating and type 2 immune responses, which worsened symptoms of food allergy. Our study supports a mechanistic link between diet and a mucolytic gut microbe in regulating food allergy.
