A Localized Materials‐Based Strategy to Non‐Virally Deliver Chondroitinase ABC mRNA Improves Hindlimb Function in a Rat Spinal Cord Injury Model

Spinal cord injury often results in devastating consequences for those afflicted, with very few therapeutic options. A central element of spinal cord injuries is astrogliosis, which forms a glial scar that inhibits neuronal regeneration post‐injury. Chondroitinase ABC (ChABC) is an enzyme capable of degrading chondroitin sulfate proteoglycan (CSPG), the predominant extracellular matrix component of the glial scar. However, poor protein stability remains a challenge in its therapeutic use. Messenger RNA (mRNA) delivery is an emerging gene therapy technology for in vivo production of difficult‐to‐produce therapeutic proteins. Here, mineral‐coated microparticles as an efficient, non‐viral mRNA delivery vehicles to produce exogenous ChABC in situ within a spinal cord lesion are used. ChABC production reduces the deposition of CSPGs in an in vitro model of astrogliosis, and direct injection of these microparticles within a glial scar forces local overexpression of ChABC and improves recovery of motor function seven weeks post‐injury.
Association between Cervical Microbiota and HPV: Could This Be the Key to Complete Cervical Cancer Eradication?

Simple Summary The microbiota can modulate immune responses and modify the physiology of the human organism, thereby increasing infective risks and a neoplastic predisposition. In this review, we focus on the composition of the cervical microbiota, to identify the risk of developing Cervical Intraepithelial Neoplasia and better understand the interaction between cervico-vaginal microbiota and human papillomavirus as a means of promoting the identification of new therapeutic strategies. In fact, no therapy for HPV is yet available. A better understanding of the cervical micro-environment could be a key element allowing complete viral clearance to be achieved in largely affected populations. Abstract The heterogeneity of the cervico-vaginal microbiota can be appreciated in various conditions, both pathological and non-pathological, and can vary according to biological and environmental factors. Attempts are still in course to define the interaction and role of the various factors that constitute this community of commensals in immune protection, inflammatory processes, and the onset of precancerous lesions of the cervical epithelium. Despite the many studies on the relationship between microbiota, immunity, and HPV-related cervical tumors, further aspects still need to be probed. In this review article, we will examine the principal characteristics of microorganisms commonly found in cervico-vaginal specimens (i) the factors that notoriously condition the diversity and composition of microbiota, (ii) the role that some families of organisms may play in the onset of HPV-dysplastic lesions and in neoplastic progression, and (iii) possible diagnostic-therapeutic approaches.
Metal Homeostasis in Pathogenic Streptococci

Streptococcus spp. are an important genus of Gram-positive bacteria, many of which are opportunistic pathogens that are capable of causing invasive disease in a wide range of populations. Metals, especially transition metal ions, are an essential nutrient for all organisms. Therefore, to survive across dynamic host environments, Streptococci have evolved complex systems to withstand metal stress and maintain metal homeostasis, especially during colonization and infection. There are many different types of transport systems that are used by bacteria to import or export metals that can be highly specific or promiscuous. Focusing on the most well studied transition metals of zinc, manganese, iron, nickel, and copper, this review aims to summarize the current knowledge of metal homeostasis in pathogenic Streptococci, and their role in virulence.
Causal Associations between Paternal Longevity and Risks of Cardiovascular Diseases

Background: Observational studies have suggested that paternal longevity is associated with reduced risks of cardiovascular diseases, yet the causal association remains to be determined. Objectives: To investigate whether Mendelian randomization (MR) results support a causal role of paternal longevity for risks of cardiovascular diseases. Methods: Genetic variants associated with paternal longevity and cardiovascular diseases were obtained from public genome-wide association study data. We used inverse variance weighted MR under a random-effects model to provide causal estimates between paternal longevity and cardiovascular diseases. Results: Paternal longevity was associated with decreased risks of coronary heart disease (odds ratio (OR): 0.08; 95% confidence interval (CI): 0.02–0.37; p = 0.001) and peripheral artery disease (OR: 0.15; 95% CI: 0.03–0.65; p = 0.011). No significant differences were observed in hypertension, atrial fibrillation, heart failure, transient ischemic attack, ischemic stroke, or cardiac death. The weighted median method revealed consistent results between genetically instrumented paternal longevity and decreased risk of coronary heart disease and peripheral artery disease. No significant differences were observed in the MR-Egger results. Multivariable MR consistently indicated causal associations between paternal longevity and decreased cardiovascular diseases. The leave-one-out analysis suggested that the causal associations were not affected by individual single-nucleotide polymorphisms. The intercept of the MR-Egger estimator and funnel plot revealed no indication of horizontal pleiotropic effects. Conclusions: Our MR analyses supported a causal role of paternal longevity for decreased risks of coronary heart disease and peripheral artery disease, which highlighted the need for better monitoring and intervention of cardiovascular diseases in populations with premature paternal death.
The Evaluation of Enterprise Resource Planning (ERP) Financial Accounting and Control Using Technology Acceptance Model

The implementation of an enterprise resource planning (ERP) system is an important part in integrating the business process of an organization in order to support its daily operations effectiveness. This research evaluates the implementation of the Financial Accounting and Control (FICO) ERP system in one of Indonesian state-owned enterprises by identifying the factors such as individual characteristics, organizational characteristics, and technological characteristics that affect the perceived usefulness and the perceived ease of use of the ERP system, as well as how they in turn affect the intention to use, the usage, and its individual impacts. This research utilizes the Technology Acceptance Model (TAM) to measure the users’ acceptance of an ERP system, which is then analyzed using the Structured Equation Model-Partial Least Squares (SEM-PLS) data analysis model. The results of the research show that partially there are exogenous variables that significantly affect the endogenous variables such as perceived ease of use of ERP against perceived usefulness of ERP, the intention to use and the perceived usefulness of ERP, complexity and compatibility against perceived ease of use of ERP, intention to use against usage, usage against individual performance, and usage against individual performance and panoptic empowerment. Simultaneously, the research also shows a significant influence. Therefore, in order to measure the users’ acceptance rate of an ERP system, then all the exogenous variables, as well as perceived usefulness of ERP, perceived ease of use of ERP, intention to use, usage of ERP, and individual impact which consists of panoptic empowerment and individual performance has to be performed.
Immediate ART and clinical outcomes in New York City among patients newly diagnosed with HIV

ABSTRACT Immediate antiretroviral therapy (iART) has been shown to decrease time to viral suppression. Our center underwent significant practice transformation to support iART, including a same-day Open Access (OA) model and enhanced care coordination. We examined whether same-day ART at linkage was associated with favorable proximate and long-term HIV care outcomes. From 2018 to 2019, patients newly diagnosed with HIV, linked to care at our institution, and iART eligible were included. We evaluated the association between iART and time to viral suppression, and between iART and initial/sustained viral suppression and retention in care. We also evaluated the association between use of OA and frequency of care coordination with the same outcomes. Of the 107 patients included, 72 initiated same-day ART at linkage and 35 did not. There was no statistically significant differences in whether patients were ever suppressed, had sustained viral suppression, or were retained in care between those who received same-day ART and those who did not. More care coordination was associated with retention in care (RR 1.21 [1.01–1.5]; p = 0.05). Organizing vital services and ensuring implementation strategies that facilitate iART, while tailoring the approach to the patient’s comfort level, is likely optimal for longitudinal HIV care engagement.
Center‐augmented ℓ2‐type regularization for subgroup learning

The existing methods for subgroup analysis can be roughly divided into two categories: finite mixture models (FMM) and regularization methods with an ℓ1‐type penalty. In this paper, by introducing the group centers and ℓ2‐type penalty in the loss function, we propose a novel center‐augmented regularization (CAR) method; this method can be regarded as a unification of the regularization method and FMM and hence exhibits higher efficiency and robustness and simpler computations than the existing methods. In particular, its computational complexity is reduced from the O(n2)$O(n^2)$ of the conventional pairwise‐penalty method to only O(nK)$O(nK)$ , where n is the sample size and K is the number of subgroups. The asymptotic normality of CAR is established, and the convergence of the algorithm is proven. CAR is applied to a dataset from a multicenter clinical trial, Buprenorphine in the Treatment of Opiate Dependence; a larger R2 is produced and three additional significant variables are identified compared to those of the existing methods.
Infective Endocarditis in High-Income Countries

Infective endocarditis remains an illness that carries a significant burden to healthcare resources. In recent times, there has been a shift from Streptococcus sp. to Staphylococcus sp. as the primary organism of interest. This has significant consequences, given the virulence of Staphylococcus and its propensity to form a biofilm, rendering non-surgical therapy ineffective. In addition, antibiotic resistance has affected treatment of this organism. The cohorts at most risk for Staphylococcal endocarditis are elderly patients with multiple comorbidities. The innovation of transcatheter technologies alongside other cardiac interventions such as implantable devices has contributed to the increased risk attributable to this cohort. We examined the pathophysiology of infective endocarditis carefully. Inter alia, the determinants of Staphylococcus aureus virulence, interaction with host immunity, as well as the discovery and emergence of a potential vaccine, were investigated. Furthermore, the potential role of prophylactic antibiotics during dental procedures was also evaluated. As rates of transcatheter device implantation increase, endocarditis is expected to increase, especially in this high-risk group. A high level of suspicion is needed alongside early initiation of therapy and referral to the heart team to improve outcomes.
Bacterial Interactions in the Context of Chronic Wound Biofilm: A Review

Chronic wounds, defined by their resistance to care after four weeks, are a major concern, affecting millions of patients every year. They can be divided into three types of lesions: diabetic foot ulcers (DFU), pressure ulcers (PU), and venous/arterial ulcers. Once established, the classical treatment for chronic wounds includes tissue debridement at regular intervals to decrease biofilm mass constituted by microorganisms physiologically colonizing the wound. This particular niche hosts a dynamic bacterial population constituting the bed of interaction between the various microorganisms. The temporal reshuffle of biofilm relies on an organized architecture. Microbial community turnover is mainly associated with debridement (allowing transitioning from one major representant to another), but also with microbial competition and/or collaboration within wounds. This complex network of species and interactions has the potential, through diversity in antagonist and/or synergistic crosstalk, to accelerate, delay, or worsen wound healing. Understanding these interactions between microorganisms encountered in this clinical situation is essential to improve the management of chronic wounds.

The capacity of the IP address space and the security of the IP protocol is one of the basic parameters of cloud computing that must be considered and valued. IPv4 protocol cannot meet the cloud computing to a large number of new network application requirements; IPv6 protocol is an inevitable choice for cloud computing development. In this article, in-depth analysis for IPv6 security issues in cloud computing environments is conducted, and IPv6 security test model in the cloud computing environment is proposed to help improve and enhance the security of cloud computing.
Collagen-coated silk fibroin nanofibers with antioxidants for enhanced wound healing

Abstract Silk fibroin nanofibers find broader applications in skin tissue engineering as wound dressings. In this study, we have prepared biocompatible collagen-coated silk fibroin nanofibers with two small molecules: sinomenine hydrochloride (SH) and kaempferol hydrate (KH) with bioactive properties for wound healing applications. The prepared nanofibrous scaffolds were characterized via different experimental techniques and the biocompatibility of the nanofibrous scaffolds was assessed using MTT assay and live/dead cell assay. The wound healing potential of the nanofibrous scaffolds was evaluated through in vivo animal model. Notably, the collagen-coated scaffolds showed improved biocompatibility and fibroblast viability over the uncoated scaffolds. The collagen-coated silk nanofibers containing KH showed good antioxidant properties and promoted wound healing in in vivo studies by minimizing inflammation and enhancing collagen deposition. Thus, the incorporation of antioxidant molecules along with collagen coating enhanced the wound healing efficiency of silk nanofibers. Graphical Abstract
Fetal and Childhood Exposure to Parental Tobacco Smoking and Arterial Health at Age 10 Years

Abstract BACKGROUND Exposure to parental tobacco smoking during fetal life and childhood is associated with adverse cardiovascular health outcomes. It is not known whether these adverse parental lifestyle exposures are also associated with changes in the structure and function of the carotid arteries in children aged 10 years. METHODS In a population-based prospective cohort study among 4,639 healthy children, we examined the associations of fetal exposure to maternal (no, first trimester only, continued), paternal (no, yes), and combined parental tobacco smoking (nonsmoking parents, mother only, father only, both parents smoked) with carotid intima-media thickness and distensibility at 10 years. We also assessed the associations of exposure to any parental tobacco smoking at ages 6 and 10 years with these outcomes. RESULTS Compared with no exposure, fetal exposure to continued maternal smoking was not associated with carotid intima-media thickness (−0.04 standard deviation score (SDS); 95% confidence interval (CI): −0.13, 0.05); and distensibility (0 SDS, 95% CI: −0.09, 0.09) at age 10 years. Fetal exposure to two smoking parents was also not associated with carotid intima-media thickness (−0.07 SDS, 95% CI: −0.16, 0.02) and distensibility (0 SDS, 95% CI: −0.09, 0.10) at this age. Exposure to any parental smoking during childhood also was not associated with these outcomes at age 10 years. CONCLUSIONS Exposure to parental tobacco smoking during fetal life and childhood was not associated with markers of arterial health in children aged 10 years. Prevention strategies aiming at minimizing smoke exposure later in life are still relevant regarding arterial health.
MCML Dynamic Register Design

This paper proposes MOS current mode logic (MCML) dynamic register. The register employs tristate buffers working in master-slave configuration. The paper also investigates the behavior of the registers on clock overlap and finds that it do not comply with the desired functionality. Two techniques to achieve clock skew insensitive behavior are proposed. The first technique puts constraints on timing parameter whereas the second technique modifies the enabling mechanism of the buffer. The register operation and their insensitivity towards clock skew are examined through simulations using TSMC 90 nm CMOS technology parameters. Various timing waveforms to demonstrate the effectiveness of the proposed techniques are also included.
OOP Analysis of TWR and OWR Systems with RF Impairments and Channel Estimation Error

In this paper, we study the effect of radio frequency (RF) impairments and channel estimation error (CEE) in multi-user two-way and one-way amplify-and-forward relay network. In particular, for both the networks, we derive the approximate signal-to-noise-plus-distortion-and-error ratio expressions and then use them to evaluate the overall outage probability and their asymptotic analysis. Based on the analytical results, it is shown that the RF impairments and CEE can severely degrade the outage performance, and even reduce the diversity order to zero. Unexpectedly, in two-way relay system, we notice that the system performance decreases with increasing number of users in a multi-user environment. Finally, numerical illustrations are done to validate our analytical expressions with the help of Monte-Carlo simulations.
Respiratory chain dysfunction in perifascicular muscle fibres in patients with dermatomyositis is associated with mitochondrial DNA depletion

Patients with dermatomyositis (DM) suffer from reduced aerobic metabolism contributing to impaired muscle function, which has been linked to cytochrome c oxidase (COX) deficiency in muscle tissue. This mitochondrial respiratory chain dysfunction is typically seen in perifascicular regions, which also show the most intense inflammatory reaction along with capillary loss and muscle fibre atrophy. The objective of this study was to investigate the pathobiology of the oxidative phosphorylation deficiency in DM.
Green Synthesis and Characterization of ZnO Nanoparticles Using Pelargonium odoratissimum (L.) Aqueous Leaf Extract and Their Antioxidant, Antibacterial and Anti-inflammatory Activities

Nanoparticles (NPs) exhibit distinct features compared to traditional physico-chemical synthesis and they have many applications in a wide range of fields of life sciences such as surface coating agents, catalysts, food packaging, corrosion protection, environmental remediation, electronics, biomedical and antimicrobial. Green-synthesized metal NPs, mainly from plant sources, have gained a lot of attention due to their intrinsic characteristics like eco-friendliness, rapidity and cost-effectiveness. In this study, zinc oxide (ZnO) NPs have been synthesized employing an aqueous leaf extract of Pelargonium odoratissimum (L.) as a reducing agent; subsequently, the biosynthesized ZnO NPs were characterized by ultraviolet-visible spectroscopy (UV-Vis), dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDX), high-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED). Moreover, aqueous plant leaf extract was subjected to both qualitative and quantitative analysis. Antioxidant activity of ZnO NPs was assessed by DPPH assay, with varying concentrations of ZnO NPs, which revealed scavenging activity with IC50 = 28.11 μg mL−1. Furthermore, the anti-bacterial efficacy of the green synthesized ZnO NPs against four foodborne pathogenic bacterial strains was examined using the disk diffusion assay, and Staphylococcus aureus (ATCC 8095), Pseudomonas aeruginosa (ATCC10662) and Escherichia coli (ATCC 25922) were found to be the most sensitive against biosynthesized ZnO NPs, whereas the least sensitivity was shown by Bacillus cereus (ATCC 13753). The anti-inflammatory effect was also evaluated for both ZnO NPs and the aqueous leaf extract of P. odoratissimum through the human red blood cells (HRBC) membrane stabilization method (MSM) in vitro models which includes hypotonicity-induced hemolysis. A maximum membrane stabilization of ZnO NPs was found to be 95.6% at a dose of 1000 μg mL−1 compared with the standard indomethacin. The results demonstrated that leaf extract of P. odoratissimum is suitable for synthesizing ZnO NPs, with antioxidant, antibacterial as well as superior anti-inflammatory activity by improving the membrane stability of lysosome cells, which have physiological properties similar to erythrocyte membrane cells and have no hemolytic activity. Overall, this study provides biosynthesized ZnO NPs that can be used as a safe alternative to synthetic substances as well as a potential candidate for antioxidants, antibacterial and anti-inflammatory uses in the biomedical and pharmaceutical industries.
Chicken DDX3X Activates IFN-β via the chSTING-chIRF7-IFN-β Signaling Axis

Asp-Glu-Ala-Asp (DEAD)-box polypeptide 3 X-linked (DDX3X) is an ATP-dependent RNA helicase, In addition to involvement of eukaryotic gene expression regulation, mammalian DDX3X has recently been found to regulate IFN-β production via the adaptor MAVS mediated cascade signaling. In our studies, we demonstrated that chicken DDX3X (chDDX3X) is also involved in the IFN-β regulation, and demonstrated that chDDX3X regulated IFN-β via an essential adaptor chicken stimulator of IFN genes (chSTING). We found that chDDX3X overexpression in DF-1 cells induced expression of IFN-β and inhibited avian influenza virus (AIV) or Newcastle disease virus (NDV) replication. Knockdown of chDDX3X decreased the production of IFN-β induced by RNA analog polyinosinic-polycytidylic acid and increased viral yield. Furthermore, chDDX3X was identified as a potential chSTING-interacting protein by co-immunoprecipitation (Co-IP) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). And exogenous Co-IP in transfected cells with or without virus-stimulations further confirmed the interaction between chDDX3X and chSTING. With the gene overexpression and RNA interference studies, the chDDX3X was confirmed to be located upstream of chSTING and activate IFN-β via the chSTING-chTBK1-chIRF7-IFN-β signaling axis. In brief, our results suggest that chDDX3X is an important IFN-β mediator and is involved in RNA- and RNA virus-mediated chDDX3X-chSTING-IFN-β signaling pathway.
Research on Differential Private Streaming Histogram Publication Algorithm

In view of the memory limitation and irreversibility of data stream, a differential private histogram publication algorithm for data stream (ASDP-HPA) is proposed in the paper, which accounts of the differential privacy model and adaptive sampling method, combined with the autoregressive integrated moving average model and dynamical sliding window technique. Compared with traditional method of noise injection for input dataset, the algorithm effectively saves the overall privacy budget, reduces the publication error and improves the usability of the streaming histogram. The results of experiment show that adoption of dynamical sliding window gains higher memory utilization. And various selection of privacy budgets validates that the algorithm is effective and feasible with higher accuracy.
