Diabetes and Exposure to Environmental Lead (Pb)

Although the increased incidence of type 2 diabetes since the 1950s is thought to be primarily due to coincident alterations in lifestyle factors, another potential contributing factor in industrialized countries is exposure of the population to environmental pollutants and industrial chemicals. Exposure levels of many environmental toxicants have risen in the same time-frame as the disease incidence. Of particular interest in this regard is the metal lead. Although overall lead exposure levels have diminished in recent decades, there is an under-recognized but persistent occurrence of lead exposure in poor underserved urban populations. Although the neural developmental pathologies induced by lead exposures have been well documented, very little is known about the effect of lead exposure on the incidence of chronic metabolic diseases such as type 2 diabetes. Although our understanding of the metabolic health effects of lead exposure is incomplete, there are studies in model systems and a small amount of epidemiological data that together suggest a deleterious effect of environmental lead exposure on metabolic health. This article reviews the human, animal and in vitro studies that have examined the effects of lead exposure on the development of diabetes and related metabolic conditions.
Knowledge, understanding, attitude, perception and views on HPV infection and vaccination among health care students and professionals in Malaysia

ABSTRACT The human papilloma virus (HPV) is known to be a major causative agent of cervical cancers and warts, limited study has been conducted on its associated factors among health care students and professionals in Malaysia. The present study was carried to explore the knowledge, understanding, attitude, perception and views about HPV infection and vaccination. A total of 576 respondents were recruited to complete a self-administered questionnaire through convenience sampling across Malaysia. 80. % and of the females respondents exhibited a positive attitude towards knowledge and understanding and 60% exhibited a positive towards attitude, perception and views. Almost 65% of the population were in agreement that HPV can be transmitted sexually, and 56.7% felt strongly that sexually active persons should essentially be vaccinated. The corresponding values were somewhat lower among the male respondents. Regression analysis suggested that knowledge and understanding were strong associated with gender, age, and occupation. Attitude, perception and views were also evidently associated with gender and age. The Ministry of Health should take steps to improve awareness among the citizens. Efforts should be made to educate people on the risk of HPV as a sexually transmitted diseases associated with HPV, and on the availability of discounted and safe HPV vaccines in government hospitals to increase the uptake rate of HPV vaccines among the Malaysian population.
Second-Order Adversarial Attack and Certifiable Robustness

We propose a powerful second-order attack method that outperforms existing attack methods on reducing the accuracy of state-of-the-art defense models based on adversarial training. The effectiveness of our attack method motivates an investigation of provable robustness of a defense model. To this end, we introduce a framework that allows one to obtain a certifiable lower bound on the prediction accuracy against adversarial examples. We conduct experiments to show the effectiveness of our attack method. At the same time, our defense models obtain higher accuracies compared to previous works under our proposed attack.
Finding Nemo’s Genes: A chromosome‐scale reference assembly of the genome of the orange clownfish Amphiprion percula

The iconic orange clownfish, Amphiprion percula, is a model organism for studying the ecology and evolution of reef fishes, including patterns of population connectivity, sex change, social organization, habitat selection and adaptation to climate change. Notably, the orange clownfish is the only reef fish for which a complete larval dispersal kernel has been established and was the first fish species for which it was demonstrated that anti-predator responses of reef fishes could distinguish predators based on their olfactory cues and that this ability is impaired by ocean acidification. Despite its importance, molecular resources for this species remain scarce and until now it lacked a reference genome assembly. Here we present a de novo chromosome-scale assembly of the genome of the orange clownfish Amphiprion percula. We utilized single-molecule real-time sequencing technology from Pacific Biosciences to produce an initial polished assembly comprised of 1,414 contigs, with a contig N50 length of 1.86 Mb. Using Hi-C based chromatin contact maps, 98% of the genome assembly were placed into 24 chromosomes, resulting in a final assembly of 908.8 Mb in length with contig and scaffold N50s of 3.12 and 38.4 Mb, respectively. This makes it one of the most contiguous and complete fish genome assemblies currently available. The genome was annotated with 26,597 protein coding genes and contains 96% of the core set of conserved actinopterygian orthologs. The availability of this reference genome assembly as a community resource will further strengthen the role of the orange clownfish as a model species for research on the ecology and evolution of reef fishes.
Joint Beamforming and Association Design for MIMO Radar

A critical task of a radar receiver is data association, which assigns radar target detections to target filter tracks. Motivated by its importance, this paper introduces the problem of jointly designing multiple-input multiple-output (MIMO) radar transmit beam patterns and the corresponding data association schemes. We show that the coupling of the beamforming and the association subproblems can be conveniently parameterized by what we term an ambiguity graph, which prescribes if two targets are to be disambiguated by the beamforming design or by the data association scheme. The choice of ambiguity graph determines which of the two subproblems is more difficult and, therefore, allows to trade performance of one versus the other, resulting in a detection–association tradeoff. We show how to design both the beam pattern and the association scheme for a given ambiguity graph. We then discuss how to choose an ambiguity graph achieving close to the optimal detection–association trade-off.
Has Knowledge Influenced Right Choice? Assessing the Feeding Practices for Infants of HIV Positive Mothers in a Rural Northern Nigeria

Background: Infant feeding is vital and a key determinant of good nutrition and health status, survival and development. Breast feeding is universal and socio-culturally acceptable method of child feeding. Breast milk is nutritionally balanced and provides immunity against diseases. However, breast milk can transmit HIV from mother to child. This has posed public health dilemma. A lot of work has been done on HIV including MTCT but there remains a dearth of information related to appropriate feeding for infants of mothers infected with HIV, especially in the African rural setting. Objective: The study was aimed at assessing infant feeding practices and viable breast milk alternatives for infants born to HIV positive mothers and how the knowledge of MTCT influence the choice of such practices in a rural community in Northern Nigeria. Method: Descriptive cross-sectional study design employing both quantitative and qualitative methodologies was used. Stratified sampling was used to sample 5 health facilities out of 16 to be included in the study. 111 HIV positive mothers with children aged 0-12 months attending services in the sampled health facilities were randomly assigned numbers and systematically sampled to participate in the study. Results: Maternal knowledge on MTCT of HIV was high (66.7%) in the study area. However, this had no association with maternal choice of infant feeding practice. The choice of alternative infant feeding practice was rather influenced by a number of factors among them; stigma and discrimination, belief about HIV transmission from mother to child (P=0.05) and HIV has no cure (P=0.03). Cow’s milk is the most preferred infant feeding option (99.1%) followed by commercial infant formula (96.4%). Conclusion: The choice of infant feeding practice is not associated with level of maternal knowledge of MTCT of HIV. Commonly used infant feeding options include cow milk, porridge and commercial formula. World Health Organization guidelines on infant feeding in HIV recommends exclusive breast feeding to infants for six months.
Early Experience With Nonporous Polyethylene Barrier Sheet in Orbital Fracture Repair.

PURPOSE The aim of this study was to evaluate the efficacy of the nonporous polyethylene barrier sheet as an alternative for nylon foil (SupraFOIL) implants in repair of orbital fractures. METHODS This is a prospective, case series using the Stryker 0.4-mm-thick nonporous polyethylene barrier sheet in all patients over the age of 18 years presenting with orbital fractures from December 2014 to June 2015. Patient's age, location of fracture, etiology of injury, presence of preoperative restriction and diplopia, and postoperative diplopia and/or enophthalmos was recorded. Institutional review board approval was received, and consent was obtained from all participants. Patients were followed for at least 6 months when possible. Scanning electron microscopy was used to compare the thickness, surface characteristics, and porosity of the nonporous polyethylene barrier and nylon foil implants. Beam deflection testing was also performed to compare the biomechanical properties of each implant. RESULTS Forty-six patients who underwent repair of orbital fractures with the nonporous polyethylene barrier sheet were included in this series. Average age was 43.3 years (range: 18-84 years). Twenty-six of 46 patients (56.5%) were males, and 20 (43.4%) were females. The most common causes of injuries were assault (38.3%), falls (25.5%), motor vehicle accident (14.9%), and sports related (10.5%). Twenty of 46 patients (43.4%) had isolated orbital floor, and 2 patients (4.3%) had isolated medial wall fractures. Fifteen patients (32.6%) had combined floor and medial wall fractures involving the inferomedial orbital strut, and 9 (19.6%) had floor fractures associated with zygomaticomaxillary complex or lateral wall fractures. Twenty-eight patients (60.9%) had preoperative diplopia. Timing of surgery was between 3 and 55 days, with the median of 11.5 days. Five of 46 patients (10.8%) had residual diplopia at their 1-week postoperative visit, 4 of those patients' diplopia had resolved at 2 months postoperatively. One patient had residual diplopia at 6-month follow up. Electron microscopy showed that the 0.4-mm nonporous polyethylene barrier implant was thinner (0.33 mm) than expected and thinner than 0.4-mm SupraFOIL (0.38 mm). Scanning electron microscopy exhibited that the surface of the nonporous polyethylene barrier was smooth and nonporous. Beam deflection testing showed that for small forces (<100 mN), the 2 materials behaved nearly identically, but at higher forces, the nonporous polyethylene implant exhibited less stiffness. CONCLUSIONS The use of nonporous polyethylene barrier sheet implant for orbital fracture repair is a safe and effective alternative to nonporous nylon foil implants. There were no complications and one case of residual diplopia (2.1%) in this case series.
Dihydromyricetin as a Functional Additive to Enhance Antioxidant Capacity and Inhibit the Formation of Thermally Induced Food Toxicants in a Cookie Model

Recently, there is a growing interest in fortifying food products with flavonoids to enhance health benefits. Naringenin, naringin, hesperetin, and dihydromyricetin are four typical flavonoids constituting a natural part of our diet. In the present work, they were fortified into a chia oil cookie model to evaluate their thermal stability during baking as well as their impact on antioxidant capacity and toxicant formation. Among them dihydromyricetin was the most unstable one (only 36.1% of which was left after baking at 180 °C for 20 min) and led to a loss of brightness in cookie. However, the antioxidant capacity of cookie fortified with dihydromyricetin was significantly enhanced compared with untreated cookie; on the other hand, dihydromyricetin showed the strongest effect to attenuate lipid and protein oxidation as well as decrease the level of fluorescent advanced glycation endproducts and carboxymethyl lysine in cookie model. Overall, among the four selected flavonoids, dihydromyricetin might be the most promising functional bakery additive enhancing the antioxidant capacity while decreasing the formation of toxicants.
Immunogenicity of a Tripartite Cell Penetrating Peptide Containing a MUC1 Variable Number of Tandem Repeat (VNTR) and A T Helper Epitope

Peptide-based vaccines for cancer have many advantages however, for optimization these immunogens should incorporate peptide epitopes that induce CD8, as well as CD4 responses, antibody and long term immunity. Cell penetrating peptides (CPP) with a capacity of cytosolic delivery have been used to deliver antigenic peptides and proteins to antigen presenting cells to induce cytotoxic T cell, helper T cell and humoral responses in mice. For this study, a tripartite CPP including a mucin 1 (MUC1) variable number of tandem repeat (VNTR) containing multiple T cell epitopes and tetanus toxoid universal T helper epitope peptide (tetCD4) was synthesised (AntpMAPMUC1tet) and immune responses investigated in mice. Mice vaccinated with AntpMAPMUC1tet + CpG show enhanced antigen-specific interferon-gamma (IFN-γ) and IL-4 T cell responses compared with AntpMAPMUC1tet vaccination alone and induced a Th1 response, characterised by a higher ratio of IgG2a antibody/IgG1 antibodies. Furthermore, vaccination generated long term MUC1-specific antibody and T cell responses and delayed growth of MUC1+ve tumours in mice. This data demonstrates the efficient delivery of branched multiple antigen peptides incorporating CPP and that the addition of CpG augments immune responses.
What If We Simply Swap the Two Text Fragments? A Straightforward yet Effective Way to Test the Robustness of Methods to Confounding Signals in Nature Language Inference Tasks

Nature language inference (NLI) task is a predictive task of determining the inference relationship of a pair of natural language sentences. With the increasing popularity of NLI, many state-of-the-art predictive models have been proposed with impressive performances. However, several works have noticed the statistical irregularities in the collected NLI data set that may result in an over-estimated performance of these models and proposed remedies. In this paper, we further investigate the statistical irregularities, what we refer as confounding factors, of the NLI data sets. With the belief that some NLI labels should preserve under swapping operations, we propose a simple yet effective way (swapping the two text fragments) of evaluating the NLI predictive models that naturally mitigate the observed problems. Further, we continue to train the predictive models with our swapping manner and propose to use the deviation of the model’s evaluation performances under different percentages of training text fragments to be swapped to describe the robustness of a predictive model. Our evaluation metrics leads to some interesting understandings of recent published NLI methods. Finally, we also apply the swapping operation on NLI models to see the effectiveness of this straightforward method in mitigating the confounding factor problems in training generic sentence embeddings for other NLP transfer tasks.
Do the adiponectin and leptin levels in preterm and term breast milk samples relate to infants’ short-term growth?

Abstract Adiponectin and leptin are involved in appetite control and body weight regulation. We aimed to evaluate the relationship between breast milk adipokine levels and short-term growth of preterm and term infants. Thirty-one preterm (median=35.3 weeks) and 34 term (median=38.7 weeks) infants were enrolled. Enzyme-linked immunosorbent assay was used to detect adipokines in mature milk. Infant growth was followed during the first 3 months. Although weight gain in the first month was insufficient, positive linear growth was observed in the following months for preterm infants, while term infants had positive steady linear growth. The median level of adipokines was found to be higher in preterm infants (P>0.05). Adiponectin showed significant negative correlations with some anthropometric measurements of term infants. However, in preterm infants, adiponectin was negatively correlated with length increment and positively correlated with body mass index (BMI) increment in the second–third month. In addition, leptin was negatively associated with the head circumference at birth in preterm infants and the triceps skinfold thickness increment in the first–second month term infants (P<0.05). In linear regression models, while gestational age, adiponectin and leptin were not related, maternal age and pre-pregnancy BMI had effects on body weight increment in 0–1 months (P<0.05). In conclusion, adiponectin may affect short-term growth, while leptin has no important effect. It would be beneficial to carry out longitudinal studies to evaluate the effects of these adipokines on the growth of infants.
Translating a spinal cord injury self-management intervention for online and telehealth delivery: A community-engaged research approach

Objective: To develop educational content and pilot test the use of tablet computers (iPads), online content management platform (iTunes U) and video conferencing (FaceTime) for delivery of a peer supported, spinal cord injury self-management intervention, using a community-engaged research approach. Design: Cross-sectional convenience sampled pilot study; evaluation using a combination of observation and questionnaires. Setting: Community-based. Participants: Individuals with SCI (n = 10) recruited from the community. Interventions: Participants engaged in a hands-on evaluation of the educational content and technology. Outcome Measures: Usability and acceptability of educational content and technology. Results: Participants were receptive and satisfied with the iPad and iTunes U platform and the video chat experience. Statements by our participants demonstrated a clear preference for interactive and multimedia platforms to promote engagement with educational materials. The use of FaceTime to facilitate contact between the participant and PN demonstrated satisfactory usability and acceptability. The hands-on evaluation process highlighted the need for consideration of connectivity for rural participants and assistive technology needs. Conclusion: Our community-engaged research approach and evaluation processes provided direct user feedback on the online and telehealth implementation of PHOENIX that will guide development of the remaining educational content, and testing of the intervention in a future feasibility trial.
NFRfinder: a knowledge based strategy for mining non-functional requirements

A challenge in requirements elicitation is to identify quality requirements, i.e. non-functional requirements (hereafter, NFR). In general, stakeholders need NFRs, but these requirements are not always explicit, they can be part of the tacit knowledge. The usual strategy adopted by requirements engineers to elicit NFRs is to act proactively by asking stakeholders their interests in qualities based on lists or catalogs. NFRFinder is a semi-automated process strategy for mining keywords. The strategy uses the keywords to find possible NFRs in unstructured texts, e.g. the meeting minutes that occur during an elicitation task. The strategy relies on catalogs, according to the NFR Framework, as a supporting knowledge base. However, to gain more confidence on the NFRFinder, we have applied it to a set of structured texts. We report on the recall and precision of NFRFinder using a gold standard built from different actors, for requirements sentences. The results are promising, and we point out towards the evolution of NFRFinder.
Many moral buttons or just one? Evidence from emotional facial expressions

ABSTRACT We investigated whether moral violations involving harm selectively elicit anger, whereas purity violations selectively elicit disgust, as predicted by the Moral Foundations Theory (MFT). We analysed participants’ spontaneous facial expressions as they listened to scenarios depicting moral violations of harm and purity. As predicted by MFT, anger reactions were elicited more frequently by harmful than by impure actions. However, violations of purity elicited more smiling reactions and expressions of anger than of disgust. This effect was found both in a classic set of scenarios and in a new set in which the different kinds of violations were matched on weirdness. Overall, these findings are at odds with predictions derived from MFT and provide support for “monist” accounts that posit harm at the basis of all moral violations. However, we found that smiles were differentially linked to purity violations, which leaves open the possibility of distinct moral modules.
Gut-Brain Psychology: Rethinking Psychology From the Microbiota–Gut–Brain Axis

Mental disorders and neurological diseases are becoming a rapidly increasing medical burden. Although extensive studies have been conducted, the progress in developing effective therapies for these diseases has still been slow. The current dilemma reminds us that the human being is a superorganism. Only when we take the human self and its partner microbiota into consideration at the same time, can we better understand these diseases. Over the last few centuries, the partner microbiota has experienced tremendous change, much more than human genes, because of the modern transformations in diet, lifestyle, medical care, and so on, parallel to the modern epidemiological transition. Existing research indicates that gut microbiota plays an important role in this transition. According to gut-brain psychology, the gut microbiota is a crucial part of the gut-brain network, and it communicates with the brain via the microbiota–gut–brain axis. The gut microbiota almost develops synchronously with the gut-brain, brain, and mind. The gut microbiota influences various normal mental processes and mental phenomena, and is involved in the pathophysiology of numerous mental and neurological diseases. Targeting the microbiota in therapy for these diseases is a promising approach that is supported by three theories: the gut microbiota hypothesis, the “old friend” hypothesis, and the leaky gut theory. The effects of gut microbiota on the brain and behavior are fulfilled by the microbiota–gut–brain axis, which is mainly composed of the nervous pathway, endocrine pathway, and immune pathway. Undoubtedly, gut-brain psychology will bring great enhancement to psychology, neuroscience, and psychiatry. Various microbiota-improving methods including fecal microbiota transplantation, probiotics, prebiotics, a healthy diet, and healthy lifestyle have shown the capability to promote the function of the gut-brain, microbiota–gut–brain axis, and brain. It will be possible to harness the gut microbiota to improve brain and mental health and prevent and treat related diseases in the future.
