An exhaustive review on state-of-the-art techniques for anomaly detection on attributed networks

Social Network sites are one of the most prominent websites used in almost every facet of life. A social network reflects relationships among social entities, including acquaintances, co-workers, or co-authors. With the extreme success of Social networks, the misuse has also been escalated and unlocked the way for various illegal behavior and security threats. Social Network anomaly detection has become a critical topic to be explored by researchers. The nature of the input data is a significant aspect of an anomaly detection technique. In the field of anomaly detection in the social network, input networks can be classified as static or dynamic, Attributed or unattributed. The number of nodes and the connections between the nodes in static networks would not change with time. Attribute networks are pervasive in various domains and constitute a vital element of modern technological architecture, where node attributes support the topological structure in data exploration. While social networks build up over time, evaluating them as if they had been static is very beneficial. Numerous studies have been done for Anomaly detection, but to the best of our knowledge, research in static attributed anomaly detection has been very limited. This review tries to portray earlier research on detecting anomalies for social static attributed networks and thoroughly discusses state-of-the-art embedding approaches

Natural products targeting the atr-chk1 signaling pathway in cancer therapy

Cancer is one of the most severe medical conditions in the world, causing millions of deaths each year. Chemotherapy and radiotherapy are critical treatment approaches, but both have numerous adverse health effects. Furthermore, the resistance of cancerous cells to anticancer medication leads to treatment failure. The rising burden of cancer requires novel, efficacious treatment modalities. Natural remedies offer feasible alternative options against malignancy in contrast to available synthetic medication. Selective killing of cancer cells is privileged mainstream in cancer treatment, and targeted therapy represents the new tool with the potential to pursue this aim. The discovery of innovative therapies targeting essential components of DNA damage signalling and repair pathways, such as ataxia telangiectasia mutated and Rad3-related Checkpoint kinase 1 (ATR-CHK1), has offered a possibility of significant therapeutic improvement in oncology. The activation and inhibition of this pathway account for chemopreventive and chemotherapeutic activity, respectively. Targeting this pathway can also aid in overcoming the resistance of conventional chemo- or radiotherapy. This review enlightens the anticancer role of natural products by ATR-CHK1 activation and inhibition. Additionally, these compounds have been shown to have chemotherapeutic synergistic potential when used in combination with other anticancer drugs. Ideally, this review will trigger interest in natural products targeting ATR-CHK1 and their potential efficacy and safety as cancer-lessening agents.

Sedative-hypnotic effects of datura arborea linn extract in experimental animals

Datura arborea Linn is a sacred plant known for over 3000 years to have been used for magical and curative purposes. It was shown to have a central nervous system depressant effect. The active substances identified were tropane alkaloids: atropine, scopolamine, and hyosine. Therefore, we aimed to find out whether the ethanol extract of Datura arborea Linn has sedative and hypnotic activity. The extract was subjected to a thiopental sodium-induced sleep test and diazepam was used as a standard drug. The plant possesses sedative-hypnotic qualities, the findings indicate that doses of 35 mg/kg (2.70.24 min), 70 mg/kg (3.80.19 min), and 140 mg/kg (4.30.20 min) decreased the control's (9.2 min) latency to fall asleep. In comparison to the control, the length of sleep was increased by 23.46 minutes for 35 mg/kg (99.002.99 min), 70 mg/kg (132.605.53 min), and 140 mg/kg (118.606.04 min), respectively. The present study established the acute toxicity of Datura arborea Linn to be less than 600 mg/kg in mice. This study indicated that the ethanol extract of Datura arborea Linn has a sedative-hypnotic activity in the diazepam-induced sleep test. It is safe to suggest that the extract acts via either β-receptor by causing hyperpolarization or a decrease in spike activity in the cell, leading to relaxation, but these effects were not blocked by β-antagonist or α2-receptor to decrease acetylcholine release, leading to relaxation of the smooth muscle.

Analgesic and anti-inflammatory potential of four varieties of bell pepper (capsicum annum l.) in rodents

The aim of the study was to evaluate the analgesic and anti-inflammatory activity of four different colored (green, yellow, orange, and red) sweet bell peppers (Capsicum annuum L.) are available at the local market in Karachi, Pakistan. Their 95% ethanol extracts at 200 and 400 mg/kg were prepared and compared with commonly used analgesics (aspirin) and anti-inflammatory agents supporting its traditional use. The analgesic effects of 95% ethanol extracts of Capsicum annum L. were investigated by acetic acid-induced writhing, tail immersion and hot plate test. The anti-inflammatory activities were observed using carrageenan-induced edema of the hind paw in rats. Animals were divided into ten groups (n=7): (1) Control (2) CAG 200 (3) CAG 400 (4) CAR 200 (5) CAR 400 (6) CAO 200 (7) CAO 400 (8) CAY 200 (9) CAY 400 and (10) Standard. All the extracts were given orally. Acute toxicity was also determined by increasing the dose to 3000 mg/kg, which showed no evidence of mortality. All extracts of Capsicum significantly increased the hot plate pain threshold and remarkably reduced the carrageenan-induced rat paw oedema. Results obtained were compared with the corresponding control group, revealing that the fresh fruit extract of all four kinds of bell pepper (200 mg/kg and 400mg/kg) possess anti-inflammatory and pain-suppressing activities possibly mediated via PG synthesis inhibition

Determinants of intention to improve oral hygiene behavior among students based on the theory of planned behavior: a structural equation modelling analysis

Introduction: The prevalence of oral hygiene behaviors (OHB) is very low among school children in Ethiopia. However, the determinants of student's readiness/intention to perform those behaviors have been remained unstudied. Objective: This study aimed to identify the determinants of oral hygiene behavioral intention (OHBI) among preparatory school students based on the theory of planned behavior (TPB). Methods and materials: An institution-based cross-sectional study was conducted among 393 students. A 98-item self-administered questionnaire was used to evaluate oral hygiene knowledge (OHK), oral hygiene behavior (OHB), and OHBI based on TPB variables [attitude (ATT), subjective norms (SN) and perceived behavioral control (PBC)]. Descriptive statistics and structural equation modeling analysis (SEM) were employed to confirm relationships and associations among study variables. A p-value of less than 0.05 and a 95% confidence interval were used to declare statistical significance. Results: A total of 393 students were participated with a response rate of 97.5%. The mean age of the participants (54% females) was 18 (± 1.3) with an age range of 16 to 24. The TPB model was well fitted to the data and explained 66% of the variance in intention. ATT (β = 0.38; 95% CI, (0.21, 0.64)), SN (β = 0.33; 95% CI, (0.05, 0.83)) and PBC (β = 0.29; 95% CI, (0.13, 0.64)) were significant predictors of OHBI, where ATT was the strongest predictor of OHBI. Conclusion: The TPB model explained a large variance in the intention of students to improve their OHB. All TPB variables were significantly and positively linked to stronger intent, as the theory suggests. Furthermore, these results suggest that the model could provide a framework for oral hygiene promotion interventions in the study area. Indeed, these interventions should focus on changing the attitudes of students towards OHB, creation of positive social pressure, and enabling students to control OHB barriers.

Dexamethasone versus dexmedetomidine as adjuvants in ultrasound popliteal sciatic nerve block for hallux valgus surgery: a mono-centric retrospective comparative study

Background and Aim: Ultrasound popliteal sciatic nerve block (UPSNB) is commonly performed in foot and ankle surgery. This study aims to assess the use of dexmedetomidine and dexamethasone as adjuvants in UPSNB for hallux valgus (HV) surgery, comparing their efficacy in producing motor and sensory block and controlling postoperative pain. The adverse event rate was also evaluated. Methods: This mono-centric retrospective study included 62 adult patients undergoing HV surgery: 30 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg and dexamethasone 4 mg (Group 1), whereas 32 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg, and dexmedetomidine 1 mcg/Kg (Group 2). At first, the visual analogue scale (VAS) was evaluated after 48 hours. The other outcomes were time to motor block regression, evaluation of the first analgesic drug intake, analgesic effect, adverse effects (hemodynamic disorders, postoperative nausea and vomiting (PONV)) and patient satisfaction. The continuous data were analyzed with student’s t-test and the continuous one with χ2. Statistical significance was set at a p-value lower than 0.05. Results: No significant difference was found in VAS after 48 hours (4.5 ± 1.6 vs 4.7 ± 1.7, p = 0.621) to motor block regression (18.9 ± 6.0 vs 18.7 ± 6, p = 0.922). The number of patients that took their first analgesic drug in the first 48 h (p = 0.947 at 6 hours; p = 0.421 at 12 hours; p = 0.122 at 24 hours and p = 0.333 at 48 hours) were not significant. A low and similar incidence of intraoperative hemodynamic disorders was recorded in both groups (hypotension p = 0.593; bradycardia p = 0.881). Neither PONV nor other complication was found. Patients in Group 1 reported a lower degree of interference with sleep (p = 0.001), less interference with daily activities (P = 0.002) and with the affective sphere (P = 0.015) along with a more satisfactory postoperative pain management (p < 0.001) as compared to Group 2. Conclusion: No significant differences were observed in the duration of motor and sensory blockade between patients in both groups. Additionally, both groups showed good pain control with a low rate of adverse effects, even if there was no clinical difference between the groups. However, patients who received dexamethasone reported experiencing less interference with their sleep, daily activities and overall emotional well-being, and overall pain control.

Verbal and spatial working memory among drug-using hiv-infected men and women

Working memory (WM) is a critical component of many neurocognitive functions. The literature has demonstrated consistently that WM impairment is more frequent and severe among substance-dependent individuals (SDIs) infected with HIV compared with uninfected SDIs; however, the SDIs who participated in these previous studies were primarily male. There are few published data on WM performance among HIV+ women with or without substance use disorders, and essentially no direct comparisons of WM performance between HIV+ men and women, regardless of substance use. We investigated potential sex and serostatus effects on WM among a sample of 360 SDIs (114 with HIV; 66% female) verified abstinent from alcohol and drugs of abuse at testing and generally comparable on substance use and comorbid characteristics. Participants were tested with the n-back task, a well-established WM measure that is sensitive to HIV-associated cognitive impairment. HIV+ men and women performed spatial and verbal versions of the n-back significantly less accurately compared with HIV− participants. Women showed slower response times compared with men on both versions, regardless of HIV serostatus. Individuals dependent on cocaine showed faster RTs compared with non-dependent users, but this effect was not apparent among opioid- or alcohol-dependent groups. Findings on n-back accuracy are consistent with our previous proposal that WM impairment represents a signature deficit among HIV+ SDIs; however, WM impairment appears less common among HIV+ women without a substance use history. The pattern of sex differences in response speed but serostatus effects on response accuracy is comparable to a recent report by our group of sex differences in learning speed but serostatus effects on delayed recall.

Thermochemical modeling and performance evaluation of freeze desalination systems

Freeze desalination (FD) is a method in which saline water is cooled below its freezing point and freshwater is separated from the brine in the form of ice crystals. FD is relatively insensitive to the salinity of the feed solution, making it suitable for desalination of high concentration brines such as the brine rejected from the seawater desalination plants. The design of the FD system and the thermochemical behavior of the brine upon freezing are critical factors in the energy performance of this method. To date, thermochemical properties of the concentrated seawater during cooling, such as the threshold of formation of ice and salt-hydrates and their corresponding cooling load of formation, are not well known. Likewise, the optimal configuration of the FD system to achieve the maximum energy efficiency has not been investigated. This work provides comprehensive data about the cooling load of freezing of concentrated brine rejected from seawater desalination plants along with the threshold of formation of ice and salt-hydrates backed-up by validation. Furthermore, the optimal configuration of the FD system is identified and the effects of the compressor isentropic efficiency and effectiveness of the system’s heat exchangers on the work consumption of the FD system were investigated.

Strategic management - concept of strategy

The strategy is a means of establishing the organisation's purpose in terms of priorities for resource allocation, action programs and long term objectives (Grant 2005). Chandler (1962) defines strategy as determining the primary long-term goals of an organisation, the adoption of courses of action, and the allocation of necessary resources. Besides, the strategy also focuses on allocating resources in relation to the organisation and its environment (Schendel & Hatten 1972). The strategy also pertains to the top management's decisions pertaining to its scope and the future direction. Such strategy covers an action plan on the organisation's future, commitments to specific products, services, and the markets.

Mediating role of empowerment between total quality management (tqm) and service recovery performance in the hotel industry

The purpose of this research was to examine the mediating effect of empowerment on the linkage between Total Quality Management (TQM) and service recovery performance in the hotel industry. Although much has been written about TQM, empowerment and service recovery performance, but the role of empowerment as a mediator in the relationship between TQM and service recovery performance has remained a relatively unexplored research area. A 93-item questionnaire is designed to measure TQM, empowerment and service recovery amongst employees in five-star hotels in Jordan, and 254 usable questionnaires were used in this study. Principal components analysis determined the factor structure and regression analysis determined the relationships between the study’s variables. The results revealed that the TQM implementations have positive effects on empowerment and service recovery performance. Moreover, the study found the full mediating effect of empowerment in the relationship between TQM and service recovery performance. Implications, limitations and future research are discussed at the end. This study proposes model of influence of TQM in service recovery performance, whereby empowerment fully mediates this relationship.

Work-life integration and female lecturers’ task performance in higher educational institutions in imo state

This study examined work-life integration and female lecturers’ tasks performance in government-owned higher educational institutions in Imo state. The correlational research design was adopted for the study. Two research questions were answered while two hypotheses were tested. The population of the study comprised 1292 female lecturers in government-owned higher educational institutions in Imo State. The sample size of the study was determined using Taro Yamane formula. Proportionate stratified random sampling technique was used to draw 406 respondents from the strata. Two sets of instruments titled; Female Lecturers’ Work-Life Integration Questionnaire (FLWLIQ) and Female Lecturers’ Task Performance Questionnaire (FLTPQ) were used for data collection. Face and content validities were ensured by experts including the researcher’s supervisor. The reliability coefficient of the FLWLIQ and FLTPQ was calculated to be 0.97 and 0.95 with the help of Cronbach Alpha. Multiple and simple regressions were used to answer the research questions. ANOVA associated with multiple regression and t-test associated with simple regression were used to test the null hypotheses at 0.05 alpha level. It was found that self-management skills and effective communication system predict female lecturers’ tasks performance by 54% in government-owned higher educational institutions in Imo state. Based on the findings, it was concluded that work-life integration is positively and moderately significant to female lecturers’ tasks performance in higher educational institutions in Imo state. It was therefore recommended among others that; management of tertiary institutions in Imo state should consider the establishment of constructive outlets for female lecturers to vent any form of inconveniences that is inimical to their job functioning so as to reduce tension. Also, management in each of the institutions should communicate staff duties in an effective manner by setting up active communication channels in each faculty.

Bacteriological qualities of sources of domestic water supply and prevalence of typhoid fever in some communities of enugu state, southeast, nigeria: a cross-sectional study

Background: From the public health point of view, the microbiological properties of domestic water supply are the most important parameters of domestic water supply because of the propensity for microbial water-related diseases. In Enugu State, statistics have shown that reported cases of waterborne diseases (including typhoid fever) have been on the increase since 2003. The aim of the study was to determine the bacteriological qualities of domestic water supply and prevalence of typhoid fever in five communities of Enugu State in connection with the rising incidence of typhoid fever in the state. Methods: This was a cross-sectional study of sources of domestic water supply and prevalence of typhoid fever in five rural communities of Ezeagu Local Government Area. 297 copies of structured questionnaire, 10 grab water samples analysed using the membrane filtration method and 227 blood samples collected for Widal test were used to generate the data for the study, analysed as frequency distributions, t-test of means difference and Pearson product moment correlations using MaxStat (version 3.60) statistical software. Results: 2 (40%) of the 5 communities complied with the WHO standard for faecal coliform counts. Prevalence of typhoid fever was high in all the communities (71.4%-100%). Only faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever. Conclusions: Since faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever, improving the bacteriological qualities of domestic water supply may help to reduce the prevalence of typhoid fever.

Comparative composition, antioxidants, and antimicrobial effects of 3- and 7-day fermented seeds of nigella sativa

The significance of fermentation is gaining more relevance due to the need for better preparation of plants, the desire for better plant constituents, and the aim for the preservation of medicinal plants. Hence, this study sets out to determine and compare the pH, proximate composition, chemical constituents, antioxidant, and antimicrobial effects of 3-day and 7-day fermented seeds of Nigella sativa. The fermentation of the seed was done for 3 and 7 days using 2.5% sugar. The pH of the sample declined from 3.5 to 3.45 during the fermentation. The proximate composition (moisture, ash, lipid, protein, and carbohydrates) was higher for the 3-day fermented sample while fiber was higher for the 7-day sample. The phytochemical constituents (tannins, saponins, phenols, alkaloids, flavonoids, phytates, oxalates, terpenoids, steroids, and glycosides) were higher for the 3-day than the 7-day sample. The Gas Chromatography-Mass spectrometry technique showed peaks that were characterized as 17 and 20 constituents on days 3 and 7 of the sample, respectively. The antioxidant capacity (ranging from 35.50% to 82.69% for the 3-day and from 37.50% to 84.99% for the 7-day sample) varies by the increasing concentration (7.81 mg/mL to 1000 mg/mL) of the sample. The diameter of zones of inhibition tested at different concentrations (25 mg/mL, 50 mg/mL, and 100 mg/mL) showed varying degrees of activity against Proteus vulgaris and Staphylococcus aureus. The zones obtained were higher 8-10 mg/mL against Staphylococcus aureus and 10-12 mg/mL against Proteus vulgaris for the 7-day fermented sample while 8.0 to 9.0 mg/mL was obtained for the 3-day fermented against Staphylococcus aureus and 8.0 to 10.0 mg/mL against Proteus vulgaris. Overall, the results of this study indicated that fermentation contributed to enhancing the bioactive components and antioxidant capacity of the fermented seeds of N. sativa thereby supporting the use of fermentation in the production of value-added functional foods.
