Background: Soil-transmitted parasites, bacterial and other biological contaminants constitute the major causes of food-borne diseases often transmitted through food and water borne routes contaminated with faeces in developing countries. Children and Women of reproductive age (WRA) have high of getting infected and being potential sources of pathogenic micro-organisms.
Objective: This study was aimed to assess and compare the prevalence and risk factors of soil-transmitted helminths and Helicobacter pylori (H. pylori) among school-aged children and women of reproductive age at selected area in Eleme Local Government Area, Rivers State.
Methods: Cross-sectional study was conducted 580 participants were enrolled in May-August 2019. The gastrointestinal parasites were examined with wet mount and formol-ether concentration techniques. Chi-square (χ2) test was used to evaluate the association between categorical variables and infection prevalence using SPSS version 21, values were considered significant when the p-value was less than 0.05.
Results: The overall prevalence of soil-transmitted helminths among children was 12.3% (37/300) whereas WRA had 12.5% (35/280). Trichuris trichura was found to be prominent among the children with 18 (6.0%) while Ascaris lumbricoides 10 (3.6%) was most prevalent among WRA. Gender based Prevalence was 56.8% (21/37) and 43.2% (16/37%) for males and females respectively. The age-related prevalence is most common among age group 11-15 years. This prevalence was not statistically significant (p>0.05). H. pylori infection prevalence among the children and WRA were 11.7% (35/300) and 26.8% (75/280). The gender-related prevalence among the males had 18 (51.4%) and females 17 (48.6%) of the children group. The age group 1-5 years showed high prevalence of H. pylori than other groups. Among WRA, age group 23-27 and 33-37 years had equal prevalence of 20 (26.7%). In consideration of co-infection between children and WRA, A. lumbricoides coinfection H. pylori 15 (53.5%) was most prevalent among children while among women of reproductive age, hookworm co-infection H. pylori 8 (50.0%) was most prevalent. Risk factors that were statistically significant (p<0.05) were among those who wash hands with soap after playing/touching soil and those dewormed in the last three months.
Conclusion: The distribution of soil-transmitted helminth infections co-infection H. pylori among children and WRA is low, however strategic planning of treatment regimen of community based should be encouraged.

Published: January 2022

AbstractHarvesting the excess energy from absorbed above bandgap photons is a promising approach to overcome the detailed balance limit for higher solar cell efficiencies. However, this remains very challenging for 2D layered halide perovskites as the fast excess energy loss competes effectively with charge extraction. Herein, the authors engineer the energy cascade manifold of quantum well (QW) states in quasi‐2D Ruddlesden–Popper perovskites by facile tuning of the organic spacer to decelerate the energy loss. The resulting excess energy loss rate is up to two orders slower compared to 3D perovskites, thus enabling efficient carrier extraction. 2D electronic spectroscopy reveals further insights into the structural and energetic disorder of these layered systems. Importantly, a judicious choice of the organic spacer holds the key to tailoring the coherent coupling between QWs that strongly influences the competition between the energy cascade and charge extraction.
Fulfilling and desperately needed: Australian media representations of responses to homelessness
Authors: Simpson Reeves Laura , Clarke Andrew , Kuskoff Ella , Parsell Cameron 
Published: January 2022

AbstractHomelessness is a significant social issue that continues to confront Australian society, despite burgeoning public and policy responses to the issue. Existing scholarship demonstrates the important role the media can play in shaping such responses by framing homelessness – and the people who experience it – in particular ways. However, to date there has been limited focus on how the media represents social responses to homelessness, or how such representations might influence public perceptions of the appropriateness of current responses. Drawing on analysis of four years of media articles (2016–2019), this article examines how the print media frames responses to homelessness in Brisbane, Australia. Our findings demonstrate that the media largely frames current responses as fulfilling and enjoyable for volunteers, and as desperately needed by people who experience homelessness. In representing the issue in this way, the media highlights the unequal power dynamics between those experiencing homelessness and those responding to homelessness. Rather than challenging this problematic power hierarchy, however, the media reifies it through its celebration of temporary and inadequate homelessness responses. We argue that such framing has the potential to promote public and policy support for responses that do little to address the underlying causes of the issue.
Nanofibrous dressing: Potential alternative for fighting against antibiotic‐resistance wound infections

Published: January 2022

AbstractThe progression of antibiotic‐resistant bacteria (ARB) as well as impaired immunity due to chronic diseases and complications, aging, and so forth pose opportunities in parallel with challenges to the wound dressing products. In a bid to address the remedies, electrospun nanofibrous membranes (ENMs) with high permeability and good biocompatibility have made an entry as wound dressings. With high specific surface area, such ENMs can pave the way for the loading and release of antimicrobial agents and further promote wound healing by mimicking the extracellular matrix structure. In this review, we have compiled a series of novel antimicrobial agents that can be substituted for antibiotics against ARB and outlined their antimicrobial mechanisms, providing an overview of the latest research to illustrate how ENMs can achieve the loading and efficient release of antimicrobial agents against ARB. Last but not least, on the basis of the demands for timely and accurate wound diagnosis, ENMs capable of colorimetric detection are featured as test‐strips for the diagnosis of wound pathogenic bacteria, in the hope of inspiring researchers to design smart wound dressings capable of diagnosis and treatment integration.

Published: January 2022

AbstractThe chance recovery of a large pottery sherd from a flat‐bottomed dish with dentate‐stamped decoration in Galley Reach, about 50 km northwest of Port Moresby, raises interesting questions concerning interactions between Lapita arrivals and the established Melanesian communities of mainland Papua New Guinea. While the geographical proximity of the find to the Caution Bay Lapita sites would suggest some connection, an analysis of the sherd indicates that it may be older than Lapita at Caution Bay. Comparisons with Island Melanesian Lapita sites indicate that the sherd is mid‐ to late Lapita in age, both in its form and decoration. As such, it joins the corpus of chance PNG mainland and near mainland Lapita finds of similar age. This developing pattern may have a different genesis to the Lapita dispersal into Remote Oceania and instead reflect trade‐based connections between island and mainland communities in the first millennium BC. The data remain ambiguous on this point.

AbstractAlthough the chemotherapeutic drug, doxorubicin, is commonly used to treat various malignant tumors, its clinical use is restricted because of its toxicity especially cardiotoxicity. The use of curcumin may alleviate some of the doxorubicin‐induced cardiotoxic effects. Especially, using the nano‐formulation of curcumin can overcome the poor bioavailability of curcumin and enhance its physicochemical properties regarding its efficacy. In this study, we systematically reviewed the potential cardioprotective effects of nano‐curcumin against the doxorubicin‐induced cardiotoxicity. A systematic search was accomplished based on Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines for the identification of all relevant articles on “the role of nano‐curcumin on doxorubicin‐induced cardiotoxicity” in the electronic databases of Scopus, PubMed, and Web of Science up to July 2021. One hundred and sixty‐nine articles were screened following a predefined set of inclusion and exclusion criteria. Ten eligible scientific papers were finally included in the present systematic review. The administration of doxorubicin reduced the body and heart weights of mice/rats compared to the control groups. In contrast, the combined treatment of doxorubicin and nano‐curcumin increased the body and heart weights of animals compared with the doxorubicin‐treated groups alone. Furthermore, doxorubicin could significantly induce the biochemical and histological changes in the cardiac tissue; however, coadministration of nano‐curcumin formulation demonstrated a pattern opposite to the doxorubicin‐induced changes. The coadministration of nano‐curcumin alleviates the doxorubicin‐induced cardiotoxicity through various mechanisms including antioxidant, anti‐inflammatory, and antiapoptotic effects. Also, the cardioprotective effect of nano‐curcumin formulation against doxorubicin‐induced cardiotoxicity was higher than free curcumin.

AbstractAn innovative, Raman spectroscopy‐based monitoring and control system is introduced in this paper for designing dynamic feeding strategies that allow the maintenance of key cellular nutrients at an ideal level in Chinese hamster ovary cell culture. The Partial Least Squares calibration models built for glucose, lactate and 16 (out of 20) individual amino acids had very good predictive power with low root mean square errors values and high square correlation coefficients. The developed models used for real‐time measurement of nutrient and by‐product concentrations allowed us to gain better insight into the metabolic behavior and nutritional consumption of cells. To establish a more beneficial nutritional environment for the cells, two types of dynamic feeding strategies were used to control the delivery of two‐part multi‐component feed media according to the prediction of Raman models (glucose or arginine). As a result, instead of high fluctuations, the nutrients (glucose together with amino acids) were maintained at the desired level providing a more balanced environment for the cells. Moreover, the use of amino acid‐based feeding control enabled to prevent the excessive nutrient replenishment and was economically beneficial by significantly reducing the amount of supplied feed medium compared to the glucose‐based dynamic fed culture.

AbstractIodination has long been employed as a successful labelling strategy to gain structural insights into proteins and other biomolecules via several techniques, including Small Angle X‐ray Scattering, Inductively Coupled Plasma Mass Spectrometer (ICP‐MS), and single‐crystal crystallography. However, when dealing with smaller biomolecular systems, interactions driven by iodine may significantly alter their self‐assembly behaviour. The engineering of amyloidogenic peptides for the development of ordered nanomaterials has greatly benefitted from this possibility. Still, to date, iodination has exclusively been applied to aromatic residues. In this work, an aliphatic bis‐iodinated amino acid was synthesized and included into a custom pentapeptide, which showed enhanced fibrillogenic behaviour. Peptide single crystal X‐ray structure and powder X‐ray diffraction on its dried water solution demonstrated the key role of iodine atoms in promoting intermolecular interactions that drive the peptide self‐assembly into amyloid fibrils. These findings enlarge the library of halogenated moieties available for directing and engineering the self‐assembly of amyloidogenic peptides.

AbstractWe report on a unique DNA aptamer, denoted MSA52, that displays universally high affinity for the spike proteins of wildtype SARS‐CoV‐2 as well as the Alpha, Beta, Gamma, Epsilon, Kappa, Delta and Omicron variants. Using an aptamer pool produced from round 13 of selection against the S1 domain of the wildtype spike protein, we carried out one‐round SELEX experiments using five different trimeric spike proteins from variants, followed by high‐throughput sequencing and sequence alignment analysis of aptamers that formed complexes with all proteins. A previously unidentified aptamer, MSA52, showed Kd values ranging from 2 to 10 nM for all variant spike proteins, and also bound similarly to variants not present in the reselection experiments. This aptamer also recognized pseudotyped lentiviruses (PL) expressing eight different spike proteins of SARS‐CoV‐2 with Kd values between 20 and 50 pM, and was integrated into a simple colorimetric assay for detection of multiple PL variants. This discovery provides evidence that aptamers can be generated with high affinity to multiple variants of a single protein, including emerging variants, making it well‐suited for molecular recognition of rapidly evolving targets such as those found in SARS‐CoV‐2.
A computational framework for estimation of mean in presence of observational error
Authors: Vishwakarma Gajendra K. , Singh Neha , Kumar Neelesh 
Published: January 2022

AbstractThis article presents a computational framework for estimation of the mean in two‐phase sampling mechanism using multi‐auxiliary variables when observational errors are observed in sample data. A competent class of estimators is proposed which encompasses several existing estimation techniques under observational error. The properties of the proposed class of estimators have been explored under large sample approximation using the Taylor series expansions method. A strive is done to obtain the optimum sample sizes for a certain cost of the survey. The impact of observational errors is assessed over the mean square error of the estimators. The simulation study is demonstrated to reflect the dominant nature of the proposed class of estimators over the existing one.

Published: January 2022

SummaryThe grid is a platform of distributing the power to the consumers; if an automatic controlling and monitoring are connected with the grid, it referred to as smart grid (SG). Self‐healing is the approach of restoring the unaffected areas without affecting the system performance. The term restoration is if a fault occurs on a distribution system, it must be isolated; after that, it can be reconfigured to restore the unaffected areas. The distribution system cannot work as efficient without the self‐healing approach because it will affect the unaffected areas without any proper reason. This paper proposed a multiagent system with controlled voltage (MAS‐CV) along with self‐healing of wireless sensor network (WSN) with proportional integral derivative (PID) controller in smart grid. At initial, the magnetic flux sensors are placed in the pole transformer for detection of flux leakage. The sensed data are transferred to the distribution grid, where the multiagent system (MAS) is established to carrying out the load restoration process (i.e., self‐healing). Connection agents (CA), monitor agent (MA), main feeder agent (MFA), backup feeder agent (BFA), supporting feeder agent (SFA), and local agent (LA) are the agents presented in the paper. Each agent is communicating via agent communication language (ACL) for the restoration process; after all the loads are restored, the voltage drop of the system is controlled by the proportional integral derivative controller. The simulation results of the proposed method show that the restoration of loads is improved and number of switching is reduced with improved data transmission. Thus, the cost of the proposed method is reduced by the reduced switches. At last, the controlled power from the distribution grid is send to the consumer.

Published: January 2022

AbstractResurrection studies are a useful tool to measure how phenotypic traits have changed in populations through time. If these trait modifications correlate with the environmental changes that occurred during the time period, it suggests that the phenotypic changes could be a response to selection. Selfing, through its reduction of effective size, could challenge the ability of a population to adapt to environmental changes. Here, we used a resurrection study to test for adaptation in a selfing population ofMedicago truncatula, by comparing the genetic composition and flowering times across 22 generations. We found evidence for evolution toward earlier flowering times by about two days and a peculiar genetic structure, typical of highly selfing populations, where some multilocus genotypes (MLGs) are persistent through time. We used the change in frequency of the MLGs through time as a multilocus fitness measure and built a selection gradient that suggests evolution toward earlier flowering times. Yet, a simulation model revealed that the observed change in flowering time could be explained by drift alone, provided the effective size of the population is small enough (<150). These analyses suffer from the difficulty to estimate the effective size in a highly selfing population, where effective recombination is severely reduced.

AbstractHigh‐quality mentoring relationships can be pivotal to recruitment, retention, and long‐term persistence in ecology majors and careers. The graduate–undergraduate student mentoring relationship can become uniquely important during activities like ecological fieldwork. However, graduate students often have little experience as research mentors, which can lead to negative research experiences for undergraduate mentees. Given the potential for mentoring relationships to impact people's decisions on pursuing ecological studies and/or careers, we created and piloted a mentoring professional development program designed around intentional mentoring. Intentional mentoring requires that mentors preemptively identify what skills and knowledge their mentee should develop as well as the practices to help mentees develop these competencies. Our rationale for using intentional mentoring was that it has the potential to increase mentors' and mentees' awareness of issues around diversity, equity, inclusion, and social justice in research experiences, in addition to developing professional competencies. To evaluate our program, we conducted focus group interviews with graduate and undergraduate student participants following a multi‐week mentoring training workshop, the primary aspect of the program. Participants described an increased valuation of intentional mentoring and a desire to be more intentional in their mentoring relationships. Graduate student mentors described an increased desire to be more intentional mentors, whereas undergraduate mentees described an increased desire to seek mentors with whom they could develop intentional relationships. Undergraduates also better recognized the importance of academic mentors. Based on our evaluation, we posit that intentional mentoring can increase the retention and persistence of students with diverse identities in ecology by fostering a sense of belonging. We advocate the implementation of mentoring training workshops as a part of academic ecological programs to increase inclusion in our discipline.
