ABSTRACT
Studying the representation of the Movement of Indigenous Peoples in G1 Roraima, having as a panorama the Cultural Studies and the postcolonial perspectives of local journalism when approaching the native communities of the State, is our main objective. Therefore, we try to observe the deficiencies of cyberjournalism and journalistic discourse to represent adequately the image of this movement, considering ethnicity as an indicator of identity. This study proposes an approximation to the conceptualization of representation, by Stuart Hall (2003), and with Fairclough (2001) and Márcia Benetti’s (2006) Discourse Analysis (DA), considering the journalist as an intersubjective individual. Based on these reflections, we carried out an observation of the published content to point out the presence of archetypes created by a society with colonial perspectives.

Systematic Isolation of Key Parameters for Estimating Skeletal Maturity on Knee Radiographs
Authors: Benedick Alex , Knapik Derrick M. , Duren Dana L. , Sanders James O. , Cooperman Daniel R. , Lin Feng-Chang , Liu Raymond W. 
Published: January 2021

Background:
The ability to estimate skeletal maturity using a knee radiograph would be useful in anterior cruciate ligament (ACL) injuries and limb-length discrepancy in immature patients. Currently, a quick, accurate, and reproducible method is lacking.

Methods:
Serial knee radiographs made 3 years before to 2 years following the chronologic age associated with 90% of final height (an enhanced skeletal maturity gold standard compared with peak height velocity) were analyzed in 78 children. The Pyle and Hoerr (PH) knee method was simplified by developing discrete stages for the distal part of the femur, the proximal part of the tibia, the proximal part of the fibula, and the patella. The Roche-Wainer-Thissen (RWT) knee method was simplified from the 36 original parameters to 14 parameters by removing parameters that were poorly defined, were not relevant to the peripubertal age range, were poorly correlated with 90% final height, or were poorly reliable on a 20-radiograph pilot analysis. We also compared the recently described central peak value (CPV) of the distal part of the femur. The Greulich and Pyle (GP) left-hand bone age was included for comparison.

Results:
In this study, 326 left knee radiographs from 41 girls (age range, 7 to 15 years) and 37 boys (age range, 9 to 17 years) were included. Stepwise linear regression showed higher correlation in predicting years from 90% final height using the modified RWT and demographic characteristics (R2 = 0.921) compared with demographic characteristics alone (R2 = 0.840), CPV and demographic characteristics (R2 = 0.866), GP and demographic characteristics (R2 = 0.899), and PH and demographic characteristics (R2 = 0.902). Seven parameters were excluded from the RWT and demographic characteristics model using stepwise linear regression and generalized estimating equations analysis, leaving 7 parameters (2 femoral, 4 tibial, and 1 fibular) in the final model. Compared with RWT and demographic characteristics (R2 = 0.921), there were minimal incremental increases by adding CPV (R2 = 0.921), GP (R2 = 0.925), or PH (R2 = 0.931).

Conclusions:
This large analysis of knee skeletal maturity systems isolated 7 discrete radiographic knee parameters that theoretically outperform the GP bone age in estimating skeletal maturity.

Clinical Relevance:
We present a modified knee skeletal maturity system that can potentially preclude the need for additional imaging of the hand and wrist in reliably estimating skeletal maturity.

Published: January 2021

Abstract
Background: Microbial contamination of edible low moisture foods poses a significant public health risk for human. In this study, the microbial quality of sweet dehulled sesame, salted dehulled sesame and the raw sesame, sold under ambient conditions were examined. The samples were collected in the cities of Burkina Faso. The first type is sweet dehulled sesame (n1 = 25); the second type is salted dehulled sesame (n2 = 25) and the third type raw sesame (n3 = 25). Assessment of the microbial quality was based on the total aerobic mesophilic bacteria, the thermotolerant coliforms, the yeasts and moulds, the E. coli, and the Salmonella spp using ISO methods. Results: The results showed the presence of microorganisms varying from ˂1.0 to 1.72x105 CFU g−1 for thermotolerant coliforms, from ˂1.0 to 6,12x106 CFU g−1 for the total mesophilic aerobic flora and from ˂1.0 to 8.10x105 CFU g−1 for yeasts and moulds. The higher contaminations rates were mostly observed in raw sesame samples. No E coli or Salmonella pathogens were detected. Based on international standards of dehydrated foods, 50.67% of the ready to eat sesames are satisficing while 17.33% are acceptable and 32% are not satisficing. Conclusion: Attention should be emphasized on the processing practices, especially in crowded places where sesames are mostly sold. The high numbers of all microbial groups in these sesame samples suggested that the production of ready to eat sesame should be improved by better hygiene. This study highlights also that ready to eat sesame might harbor a wide range of microorganisms when processes are weak of hygiene.

Abstract
Aim: The study aimed to investigate the relationship between the occurrence of Severe Early Childhood Caries (S-ECC) and breast milk lactose, in infants aged 12 to 24 months.Material and Methods: This cross-sectional descriptive-analytical study was carried out in April to July 2020 on 30 children aged 12 to 24 months with or without S-ECC who were solely breastfed Also, the mothers answered questions about their breastfeeding. After the child's dental visit, the mother was asked to express 10 to 20 ml of her milk as a sample and give it to the researchers. The samples were immediately kept at -4 ° C and then they were tested to lactose measurement. Finally, the test results were analyzed by SPSS 21 software. Results: The average amount of lactose in the breast milk of cases with S-ECC infant was 5.74g/100 ml, and the average amount of lactose in the breast milk of cases without S-ECC infant was 4.64g/100 ml. There was no significant difference in lactose concentration between the two groups (p=0/64). The average number of breastfeeding times in cases with S-ECC infants was 7.87 per day while in the healthy cases this was 7.33 per day. There was no significant difference between the numbers of breastfeeding times per day in the two groups.Conclusion: According to this study, the average level of lactose in the breast milk samples was lower than the average level of lactose in breast milk in other countries, and the amount of lactose in breast milk of children with S-ECC was slightly higher than the amount of lactose in breast milk in children with healthy teeth.
Integrated Photosynthetic and Metabolic Constitutional Dynamic Networks―An “Artificial Leaf”
Authors: Willner Itamar , Wang Chen , Neumann Ehud , Nechushtai Rachel 
Published: January 2021

Abstract
Integration of a photosynthetic network with an assimilation, metabolic network is the fundamental prerequisite to construct an “artificial leaf”. Nucleic acid-based constitutional dynamic networks provide the building modules to construct integrated, intercommunicated networks mimicking photosynthesis. Two constitutional dynamic networks composed each of four constituents provide the photosynthetic and metabolic networks. In the photosynthetic network, photoinduced electron transfer from the Zn(II)-protoporphyrin photosensitizer to a bipyridinium electron acceptor is activated, followed by the biocatalytic reduction of NADP+ to NADPH, in analogy to photosystem I in native photosynthesis. In the metabolic network, the biocatalyzed-oxidation of lactate to pyruvate proceeds, followed by the metabolic transformation of pyruvate to L-alanine. The guided dynamic feedback-driven intercommunication of the networks is accomplished, leading to the function as an “artificial leaf”.
Institutional quality causes social trust: Experimental evidence on trusting under the shadow of doubt

Published: January 2021

Abstract
Social trust underlies virtually any social and economic interaction and is a crucial ingredient for successful collective action. What causes social trust to develop, however, remains poorly understood. Institutional quality has been proposed as a candidate driver and has been shown to correlate with social trust. We provide experimental evidence for the causal direction of this relationship. We first exogenously expose the participants to institutions of different quality, defined as their ability to prevent corrupt behaviours on behalf of administrators. We then measure social trust among the participants using a trust game. We find that individuals exposed to settings with low institutional quality trust others significantly less. Moreover, using novel survey data we show that our experimental results correspond to correlational patterns usually found across countries. The paper makes a step forward in the decades-long search for the causality between institutional quality and social trust.
Gene Expression and Alternative Splicing Dynamics Are Perturbed in Head Transcriptomes of Heterospecifically Mated Females
Authors: Diaz Fernando , Allan Carson , Markow Therese , Bono Jeremy , Matzkin Luciano 
Published: January 2021

Abstract
Background

Despite the growing interest in the female side of copulatory interactions, the roles played by alternative splicing mechanisms of pre-RNA and the epistatic effects of these interactions on tissues outside of the reproductive tract have remained largely unknown. Here we addressed these questions in the context of con- vs heterospecific matings between Drosophila mojavensis and its sister species, D. arizonae. We analyzed transcriptional responses in female heads using an integrated investigation of genome-wide patterns of gene expression, including differential expression (DE), alternative splicing (AS) and intron retention (IR).
Results

Our results indicated that early transcriptional responses were largely congruent between con- and heterospecific matings but are substantially perturbed over time. Conspecific matings induced functional pathways related to amino acid balance previously associated with the brain’s physiology and female postmating behavior. Heterospecific matings often fail to activate regulation of some of these genes and induce expression of additional genes when compared with those of conspecifically-mated females. These results are consistent for all transcriptional mechanisms with some distinctions: DE genes were mostly linked to pathways of proteolysis and nutrient homeostasis, while AS genes are more related to photoreception and muscle assembly pathways.
Conclusions

IR seem to be an important mechanism of DE regulation during the female postmating response. While AS genes evolve at slower evolutionary rates than the genome background, DE genes evolve at much higher rates, similar or even higher than those of seminal fluid proteins, which unveil their potential role for reproductive barriers and the extent of sexual conflict.
Proxies for COVID-19 Diagnosis for Adults in Resource Limited Settings: A Case Series Study in Zambia.&nbsp;
Authors: Mutengo Katongo H , Kachimba John S , Mupeta Francis 
Published: January 2021

Abstract
The novel coronavirus disease of 2019 (COVID-19); caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has presented a unique range of clinical manifestations. Thought to be primarily a respiratory disorder during its early outbreak in China in early December of 2019, it has now emerged from various scientific studies that the clinical manifestation of COVID-19 is indeed protean. This paper is aimed at exploring various proxies that can be used to increase the index of suspicion for COVID-19 in resource-limited settings like Zambia by reviewing four cases that presented to our health facilities. We hope this will help reduce healthcare costs through instituting early and more targeted treatment approaches.
Atomic Engineering Bifunctional Niobium (V)-based Heterostructure Nanosheet for High Efficiency Lean-Electrolyte Lithium-Sulfur Full Batteries

Published: January 2021

Abstract
High-efficiency lithium-sulfur (Li-S) batteries depend on advanced electrode structure that can attain high sulfur utilization at lean-electrolyte and limited lithium. Herein, a twinborn holey Nb4N5-Nb2O5 heterostructure is designed as a dual-functional host for both redox-kinetics-accelerated sulfur cathode and dendrite-inhibited Li anode simultaneously for long-cycling and lean-electrolyte Li-S full batteries. Benefiting from the accelerative polysulfides anchoring-diffusion converting efficiency and electronic-conducting properties of Nb4N5-Nb2O5, polysulfide-shutting is significantly alleviated. Meanwhile, the lithiophilic nature of holey Nb4N5-Nb2O5 is applied as ion-redistributor for homogeneous Li-ion deposition. Taking advantage of these merits, the Li-S full batteries present the excellent electrochemical properties, including a minimum capacity decay of 0.025% per cycle, and a high areal-capacity of 5.0 mAh cm− 2 at sulfur loading of 6.9 mg cm− 2, corresponding to negative to positive capacity ratio (2.4:1) and electrolyte to sulfur ratio (5.1 µl mg− 1). Therefore, this work opens a new avenue for boosting high-performances Li-S batteries towards practical applications.
Determining Future Aflatoxin Contamination Risk Scenarios for Corn in Southern Georgia, USA using Spatio-temporal Modelling and Future Climate Simulations
Authors: Kerry Ruth , Ingram Ben , Garcia-Cela Esther , Magan Naresh , Ortiz Brenda V. , Scully Brian 
Published: January 2021

Abstract
Mycotoxins are toxins produced by fungi which are harmful to humans and animals and can contaminate staple crops. Aflatoxins are particularly toxic and can cause liver cancer so the permitted levels in foodstuffs are legislated. Batches of grain where average aflatoxin concentrations are higher than legislative thresholds are rejected or sold at a lesser price for a more limited range of use. High maximum temperatures and low rainfall have been shown to increase contamination. For corn grown in Southern Georgia, USA, June weather is particularly important as this coincides with the sensitive mid-silk growth stage. An AFs survey and weather data have been used to show the association between AFs and June weather [1]. The risk factors were June maximum temperatures >33˚C and June rainfall <50mm, the 30-year normals for the region. Future climate data were estimated for each year (2000-2100) and county in southern GA using the RCP 4.5 and RCP 8.5 emissions scenarios and weather risk factors were calculated. The number of counties with June maximum temperatures >33˚C and rainfall <50mm increased significantly between 30-year time periods. The percentage of years that counties exceeded thresholds was greater for the RCP 8.5 than the RCP 4.5 scenario. A change in the spatial distribution of high-risk counties was seen over time. The results suggest the need for changes in the where crops are grown or the employment of adaptation strategies such as planting more resistant varieties, improving irrigation and planting earlier to avoid increasingly frequent rejection of grain batches. There were significantly more counties with June maximum temperatures >33˚C and June rainfall <50mm in 2010-2040 compared to 2000-2030. This suggests that adaptation strategies should be employed as soon as possible.
