Protective effect of Aloe vera gel extract plant on liver diseases of experimental rats

The present study was carried out to investigate the protective role of Aloe vera gel plant extract on carbon tetrachloride CCl4 induced changes in liver enzymes of albino rats. Aloe vera is a medicinal plant belonging to the family Liliaceae, which has a wide range of therapeutic applications. Sixty-four male Albino rats weighing about 130±5 g were taken and divided into eight groups, each with eight rats. The first group is the control (-) and fed on normal diet for 6 weeks. The second group received subcutaneous injection with CCL4 in paraffin oil (50% v/v 2 ml/kg) twice per week for 2 weeks to induce chronic damage in the liver tissue and fed on normal diet (control +). The third, fourth and fifth groups were injected with CCL4 in paraffin oil twice per week for 2 weeks then fed on 0.3, 0.6 and 0.9ml Aloe vera suspension gel (50 mg/mL), respectively by epi-gastric tube for remnant 4 weeks (injection groups). The sixth, seventh and eighth groups fed first on normal diet plus 0.3, 0.6 and 0.9ml Aloe vera suspension gel, respectively by epi-gastric tube for first 4 weeks then they were injected with CCL4 in paraffin oil twice per week for remnant 2 weeks with continued fed on the same concentrations of Aloe vera suspension gel (protected groups). The results indicated that Aloe vera powder increased the nutritional value of all treatments (protein, fat, carbohydrate and crude fiber), vitamin E (6.54μg/ml) and phenols (0.39 mg/100mg). Also, body weight gain (BWG) in protected group with 0.9 ml Aloe vera suspension gel (50 mg/mL) recorded the best result (58.90%) comparing with the control (-) (42.92%). Injected groups showed ratios of weight change or suffered a weight loss in liver comparing with control (+), ranged from -34.78 in 0.3ml to -11.37% in 0.9ml Aloe vera suspension gel after 6 weeks. Feeding rats on different ratios of Aloe vera gel decreased serum AST and ALT enzymes compared to the control (+) group. Also, decreased the mean values of uric acid, urea and creatinine in all tested groups was noticed compared to the control (+) group (2.43±0.17, 38.00±5.0 and 0.86±0.12, respectively). The best reduction in lipid profile was (89.60±12.41) for the triglycerides in high concentration of Aloe vera gel (0.9 ml) and follow by 0.6ml (90.60±18.57) and 0.3ml (91.80±8.81) comparing with control (+) in protected group. Aloe vera improved liver and kidney histopathology in carbon tetrachloride induced hepatotoxicity in rats fed on different ratios of its extract (protective groups).
Three convergence results for inexact orbits of nonexpansive mappings

In this paper we study the convergence of inexact iterates of nonexpansive mappings which take a nonempty, closed subset of a complete metric space into the space, under the presence of summable errors, and generalize the known results in the literature for nonexpansive self-mappings of the complete metric space.
Privacy Icons:

Although the institution of consent within the General Data Protection Regulation intends to facilitate the exercise of personal autonomy, reality paints a different picture. Due to a host of structural and psychological deficits, the process of giving consent is often neither informed nor does it foster self-determination. One key element in addressing this shortcoming is the visualisation of relevant information through icons. This article outlines a risk-based methodology for the selection, design and implementation of such privacy icons. It lays the groundwork for identifying risky data processing aspects as a first step in a larger project of creating a privacy icons set to accompany privacy policies. The ultimate goal of the privacy icons is to assist users in making better informed consent decisions through the visualisation of data processing aspects based on their inherent risks.
The Impact of Age on Noise Sensitivity in Cochlear Implant Recipients

Objective: To evaluate the impact of different open set sentence recognition tests in quiet, +10 dB signal to noise ratio (SNR), and +5 dB SNR in adult cochlear implant (CI) recipients above and below 65 years of age. Study Design and Setting: Multi-institution, prospective, non-randomized, single-subject repeated measures design. Patients: Ninety six adults more than or equal to 18 years old with postlingual bilateral sensorineural hearing loss. Interventions: Participants received a CI532 in one ear. Speech perception measures were evaluated before and 6-months after activation. Main Outcome Measure(s): Subjects completed consonant-nucleus-constant (CNC) words in quiet and AzBio sentences in noise using +10 and +5 dB SNR, and Montreal Cognitive Assessment (MOCA). Results: Ninety six adult patients were enrolled (n = 70 older [≥65 yr], n = 26 younger [<65 yr]). There was no difference in CNC scores (CI alone 58.4% versus 67.5%, p = 0.0857; best aided 66.7% versus 76.1%, p = 0.3357). Older adults performed worse on AzBio +10 dB SNR compared with younger patients (CI alone 37.4% versus 56.9%, p = 0.0006; best aided 51.4% versus 68.2%; p = 0.01), and in AzBio +5 dB SNR (CI alone 7.7% versus 11.2%, p = 0.0002; best aided 15.3% versus 22.3%, p = 0.0005). The magnitude of change in AzBio +10 dB SNR was significantly less in older adults in CI alone (15.3% versus 22.3%; p = 0.0493) but not best aided (21.5% versus 31.3%; p = 0.105). The magnitude of change was drastically worse in AzBio +5 dB SNR for older adults (CI alone 6.7% versus 22.1%, p = 0.0014; best aided 9.5% versus 21.5%; p = 0.0142). There was no significant difference in MOCA between the two age groups. Conclusions: While both older and younger patients have similar outcomes with respect to CNC word scores in quiet, the addition of noise disproportionally impacts older patients. Caution should be exercised testing the elderly in noise; testing in noise may disproportionally impact performance expectations and should be more carefully considered when used for candidacy criteria and counseling. Future studies need to further investigate the disproportionate effect of noise on candidacy testing and its impact on how elderly patients are qualified.
Molecular dynamics analysis of wetting behavior of nano water drops on quartz sand surface

The wettability mechanism of soil–water interfaces is of significant importance in geotechnical engineering. However, the effect of different contact angles on unsaturated sand soil behavior has been less understood. In this study, the wetting behavior of nano water droplets on various silica substrates is investigated using molecular dynamics. Seventeen groups of simulation systems with different interaction potential energies (εSi = 0.008, 0.04, 0.2, 0.4, 0.6, 0.8, 1, 2 kcal/mol) and temperatures (T = 273, 298, 323, 353 K) are conducted. The results show that the contact angles varies intensively with interaction potential energies from 108.5° to 18.1°, which indicates a transition from hydrophobic to hydrophilic and wettability enhancement along with the increase of interaction potential energy. Simulation results also show that contact angles increase with the increase of temperature, whatever the hydrophobic or hydrophilic of the silica surface. Such phenomena are interpreted from the perspective of microstructure, along with the performance of macrostructure. In addition, results show that the contact angles are independent of the thickness and width (length) of silica substrate.
Social Media Expression and User Predispositions: Applying the Differential Susceptibility to Media Effects Model to the Study of Issue Polarization

The ability of social media users to express themselves online should be influential for opinion formation, including potential polarization. Still, little is known about how expression interacts with users’ psychological predispositions, especially for controversial topics. The potential for expression to relate to support for social media-based racial justice movements, which could also be affected by underlying feelings of racial resentment, is particularly interesting. We apply the Differential Susceptibility to Media Effects Model (DSMM) to the study of the relationship between social media expression and issue polarization regarding Black Lives Matter. In a survey of social media users conducted during the 2016 U.S. presidential election, we find that racial resentment moderates the relationship between social media expression and support for racial justice movements. Among low-resentment social media users, more frequent expression was associated with less support for Black Lives Matter. In addition, low- versus high-resentment users who expressed themselves on social media more frequently were more polarized in their support for All Lives Matter but less polarized in their support for Black Lives Matter. In line with the DSMM, our findings highlight that users’ psychological predispositions must be taken into account when determining how social media expression relates to issue polarization.
Mexico

The Federation of Mexico, with 31 States and Mexico City, has a population of 129 million people with large and diverse infrastructure needs. Successive Mexican governments have recognized the importance of public investment for promoting economic growth and have given priority to infrastructure needs in the National Development Plan and the National Infrastructure Program. Some progress has been made; however, large infrastructure needs remain.
Performance Analysis and Deep Learning Design of Wireless Powered Cognitive NOMA IoT Short-Packet Communications With Imperfect CSI and SIC

In this article, we study wireless-powered cognitive nonorthogonal multiple access (NOMA) Internet of Things (IoT) networks with short-packet communications to improve spectrum utilization and sustainability, as well as reduce the latency under imperfect channel state information (CSI) and successive interference cancelation (SIC). For performance evaluation, closed-form expressions for the block error rate (BLER) of the NOMA users, goodput, energy efficiency, latency, and reliability are derived. To gain some further insights into the system design, two scenarios can be taken into account for the positions of the primary receivers: 1) they are located near the secondary network and 2) they are located far away from the secondary network. Moreover, we propose an effective algorithm to minimize the BLERs of the NOMA users by optimizing power allocation coefficients. In addition, a novel multi-output deep-learning (DL) framework is designed to simultaneously predict the BLERs and goodputs of users towards real-time configurations for IoT systems. Numerical results show the outstanding performance of the proposed system over the orthogonal multiple access (OMA) one in terms of the BLER and goodput. Moreover, the proposed system achieves a lower latency and higher reliability compared to the long packet communications under the same channel settings. Furthermore, our designed multioutput DL also exhibits the lowest error performance and a short run-time prediction compared to the other multioutput regression models, while the predicted results using the DL model are almost matched with the simulation ones.
Coprecipitation synthesis of α-(La,Yb,Er)2W2O9 tungstate as a novel upconversion phosphor for optical thermometry

ABSTRACT Phase-pure α-(La,Yb,Er)2W2O9 upconversion (UC) phosphors were synthesized via room temperature coprecipitation and subsequent calcination at 1073–1273 K. The pH of the coprecipitation system and the RE3+ to WO4 2- ratio were found crucial for the formation of the target α phase. Phase transformation from cubic β-(La,Yb,Er)2W2O9 to triclinic α-(La,Yb,Er)2W2O9 occurred when calcination temperature was above 873 K. The UC luminescence including power/temperature dependent emission, decay kinetics of the main emission, emission color, and underlying UC mechanism were systematically investigated. The phosphor exhibited bright green luminescence under 978 nm laser excitation. The main emission (4S3/2→4I15/2) was analyzed to decay in a single exponential manner and have a decay time of 153.86 μs at room temperature. A three-photon mechanism was suggested responsible for the observed UC luminescence through analyzing the UC intensity against excitation power via logarithmic data transformation. The performance of optical temperature sensing was evaluated and compared with other typical UC phosphors. It was shown that the phosphor has relatively high maximum SA and SR values of 0.02694 K−1 (548 K) and 0.01699 K−1 (298 K) for the thermally coupled 2H11/2 and 4S3/2 energy levels in the 298–548 K temperature range.
The Multifaceted Role of Annexin A1 in Viral Infections

Dysregulated inflammatory responses are often correlated with disease severity during viral infections. Annexin A1 (AnxA1) is an endogenous pro-resolving protein that timely regulates inflammation by activating signaling pathways that culminate with the termination of response, clearance of pathogen and restoration of tissue homeostasis. Harnessing the pro-resolution actions of AnxA1 holds promise as a therapeutic strategy to control the severity of the clinical presentation of viral infections. In contrast, AnxA1 signaling might also be hijacked by viruses to promote pathogen survival and replication. Therefore, the role of AnxA1 during viral infections is complex and dynamic. In this review, we provide an in-depth view of the role of AnxA1 during viral infections, from pre-clinical to clinical studies. In addition, this review discusses the therapeutic potential for AnxA1 and AnxA1 mimetics in treating viral infections.
Impact of Financial Institution on Commercial Banks (Case Study: Amal and Dahabshiil Banks in Mogadishu)

The Bank of England has had much success and as a result many nations have followed its lead in creating central bank systems of their own. The United States is one of these nations. The two nations have many similar banking objective and strategies on how to best achieve the objectives. These nations also differ greatly in some aspects of their banking philosophies. The currencies of the both nations are strong held around the world. Their monetary policies and bank regulations differ in some aspects, but both nations banking systems are held to high esteem worldwide. The banking systems of the United States and the United Kingdom were born of the same origins but differ in some major aspects of practice (Pierre 2001).
Cognitive Interviewing

The Cognitive Interview (CI) is a well-established protocol for interviewing witnesses. The current article presents a study space analysis of laboratory studies of the CI together with an empirical meta-analysis summarizing the past 25 years of research. The study space comprises 57 published articles (65 experiments) on the CI, providing an assessment of the boundary conditions underlying the analysis and application of this interview protocol. The current meta-analysis includes 46 pub- lished articles, including 20 articles published since the last meta-analysis conducted a decade earlier (Ko¨hnken, Milne, Memon, & Bull, 1999). Reassuringly for practitioners, the ﬁndings of the original meta-analysis were replicated with a large and signiﬁcant increase in correct details and a small increase in errors. In addition we found that there were no differences in the rate at which details are confabulated. Importantly, the effect sizes were unaffected by the inclusion of recent studies using modiﬁed versions of the CI. The CI appeared to beneﬁt older adult witnesses even more than younger adults. We highlight trends and gaps in research and discuss how our ﬁndings can inform policy and training decisions.
Natural remedies for hyperlipidemia: A review

Hyperlipidemia is a popular disorder and a state of body where there is elevated level of triglyceride above 200mg/dl, LDL above 160mg/dl, Total cholesterol above 200mg/dl and HDL below40mg/dl. Now it can be found on every other person, when LDL increases it travels through our blood vessels and tends to accumulate in the vessels the accumulation is not for lipids only it consists of calcium and fibrous plaque, and this scenario leads to atherosclerosis. Atherosclerosis causes narrowing of blood vessels, leads to lesser blood flow to the heart results in angina pectoris and gradually heart attack. There are many marketed medicines fighting against this, but they have adverse effects like muscle toxicity. Here, are some natural remedies which we come across everyday are fighting these situations which are very easily available in nature, and we can take it in our regular diet.
Fungi Detected in the Previous Year’s Leaf Petioles of Fraxinus excelsior and Their Antagonistic Potential against Hymenoscyphus fraxineus

Studies on fungal communities in the previous year’s leaf petioles of Fraxinus excelsior found in litter in five ash stands in southern Poland were made in 2017. Fungi were identified on the basis of isolation from 300 surface sterilized leaf petioles and by in situ inventory of fruit bodies (on 600 petioles, in spring and autumn). Identification was based on morphology of colonies and fruit bodies, and sequencing of ITS region of the rRNA gene cluster. In total, 2832 isolates from 117 taxa (Ascomycota—100; Basidiomycota—15; Mucoromycota—2 taxa) were obtained with the isolation method. The most frequent taxa (with frequency >10%) were: Nemania serpens, Hymenoscyphus fraxineus, Alternaria sp. 1, Boeremia sp. , Helotiales sp. 1, Epicoccum nigrum, Venturia fraxini, Fusarium sp. , Fusarium lateritium, Nemania diffusa, Typhula sp. 2 (in descending order). In total, 45 taxa were detected with the in situ inventory method. Eleven taxa were classified as dominant: Hymenoscyphus fraxineus, Venturia fraxini, Leptosphaeria sp. 2, Cyathicula fraxinophila, Typhula sp. 2, Hypoderma rubi, Pyrenopeziza petiolaris, Cyathicula coronata, Hymenoscyphus scutula, Leptosphaeria sclerotioides and Hymenoscyphus caudatus. Among 202 leaf petioles colonized by H. fraxineus, 177 petioles also showed fructification of 26 other fungi. All the isolated saprotrophs were tested in dual-culture assay for antagonism to two strains of H. fraxineus. Three interaction types were observed: type A, mutual direct contact, when the two fungi meet along the contact line (occurred with 43.3% of test fungi); type B, with inhibition zone between colonies (with 46.9% of test fungi); type C, when the test fungus overgrows the colony of H. fraxineus (with 9.8% of test fungi). The possible contribution of the fungal saprotrophs in limiting of the expansion of H. fraxineus in ash leaf petioles, which may result in reduction in the inoculum of ash dieback causal agent, is discussed.
Firm Value in a Situation of Free Cash Flow and Investment Sensitivity, External Finance Constraint and Information Asymmetry

: Good company value is an important goal of the company. But companies that have many stakeholders and face various problems such as conflict of incentives and information asymmetry, often have difficulty in maximizing the value of their companies. A fall in the value of a company can harm all parties including investors. The supervisory system for company management decisions is very necessary to reduce losses and adverse effects from the decline in company value. However, in-depth research on the company's value model in situations where there is sensitivity to cash flows and investment, information asymmetry and restrictions on external funding are still rarely carried out. The research objective is to test the company's value model in situations there is free cash flow, investment, information asymmetry, and external funding restrictions. The study population is a non-banking company listed on the Indonesia Stock Exchange in 2014-2016. This study uses secondary data. The dependent variable of this study is the value of the company and the independent variable is the sensitivity of cash and investment flows, information asymmetry, and external funding restrictions. The data analysis method used in this study is a multiple regression analysis model. This study finds that free cash flow, investment and external funding restrictions influence firm value.
Application of phosphogypsum to solidification of silty soil: Mechanical properties and microstructure

Abstract As a type of common industrial waste, phosphogypsum (PG) has raised concerns about environmental pollution and its comprehensive usage. However, scholars need to deepen the research on the application of PG in the solidification of silty soils. The impacts of PG on the microstructure and mechanical properties of solidified soil remain unknown under complex environmental conditions. Firstly, combined with several consolidation tests, this study analyses the impact of different PG contents on the compression modulus of silty soil with a cement-lime curing agent. Secondly, a scanning electron microscopy (SEM) test was used to take microscopic photos, and Image-Pro Plus 6.0 (IPP 6.0) software was used to process microscopic photos. Then, three microstructure parameters (Dp, Db and e) of solidified silty soil were calculated. Finally, the connection between the compression modulus and the microstructure parameters was assessed quantitatively. Results revealed that PG can stimulate the formation of calcium silicate hydrate (C–S–H) gels and react with calcium aluminate to produce ettringite. As a result, the compression modulus of solidified silty soil increased from approximately 7.39% to 51.3%. Given the excessive volume expansion produced by ettringite, the compression modulus with 4% of PG declined from 4.76% to 6.8% after reaching its maximum 24.98 MPa at 14 days of curing. A linear relationship was observed between the compression modulus and the three microstructure parameters at the declining stage of the compression modulus. The correlation coefficient R 2 of fitting lines were all greater than 0.9, thus representing the connection between the macroscopic mechanical properties and the microstructure of the solidified silty soil. This study seeks to provide theoretical basis and practical experiences for the efficient utilization of PG in the field of soil solidification.
Multi-Keyword Ranked Searchable Encryption with the Wildcard Keyword for Data Sharing in Cloud Computing

Multi-keyword ranked searchable encryption (MRSE) supports multi-keyword contained in one query and returns the top-k search results related to the query keyword set. It realized effective search on encrypted data. Most previous works about MRSE can only make the complete keyword search and rank on the server-side. However, with more practice, users may not be able to express some keywords completely when searching. Server-side ranking increases the possibilities of the server inferring some keywords queried, leading to the leakage of the user’s sensitive information. In this paper, we propose a new MRSE system named ‘multi-keyword ranked searchable encryption with the wildcard keyword (MRSW)’. It allows the query keyword set to contain a wildcard keyword by using Bloom filter (BF). Using hierarchical clustering algorithm, a clustering Bloom filter tree (CBF-Tree) is constructed, which improves the efficiency of wildcard search. By constructing a modified inverted index (MII) table on the basis of the term frequency-inverse document frequency (TF-IDF) rule, the ranking function of MRSW is performed by the user. MRSW is proved secure under adaptive chosen-keyword attack (CKA2) model, and experiments on a real data set from the web of science indicate that MRSW is efficient and practical.
