The relationship between mentalization and borderline personality features in adolescents: mediating role of emotion regulation

ABSTRACT Dysfunctions in both emotion regulation and mentalization capacity might be reasons behind borderline personality features. This study investigated the mediating role of emotion regulation between mentalization and borderline personality features in adolescents. We recruited 218 adolescents (mean of age = 16.45 ± 1.01 years old, 62.0% girls) based on convenience sampling from high school students. We evaluated mentalization using reflective functioning questionnaire (RFQ), emotion regulation with difficulties in emotion regulation scale (DERS), and borderline personality features with borderline personality features scale for children (BPFSC). There were significant associations between mentalization, emotion regulation, and borderline personality features. Difficulties in emotion regulation mediated between mentalization and borderline personality features. Mentalization deficits and emotion dysregulation contribute significantly to borderline personality features in adolescents. Mentalization deficits might affect borderline personality features’ development via its effect on emotion regulation. Prevention and treatment plans for borderline personality disorder should focus on emotion regulation and mentalization.
The Effects of Zataria Multiflora Essential Oil on Some Characteristics of Sultana Table Grapes Contaminated with Botrytis cinerea

The object of this research was to find an alternative to fungicide for the prevention of post- harvest fruits. Therefore the effect of Zataria multiflora essential oil on the quality of Sultana grapes following the harvest was investigated. The essential oil was extracted by hydro-distillation and analyzed using a combination of GC and GC/MS. The results indicated a high percentage of anti-fungal components such as Thymol (44.4%) and Carvacrol (26.3%) in the extracted essential oil. The grapes were contaminated with Botrytis cinerea spores suspension at the concentration of 5×10 5 per ml sterile distilled water. The samples were treated with suspension of 0 to 200 and 400 mgL -1 Zataria multiflora essential oil and stored at 4 ° C. Samples were examined and experimental design in a completely randomized design with three replications were employed. The results revealed that by increasing the concentrations of the essential oil, the anti-fungal activity against Botrytis cinerea was increased.
Assessment of environmental condition and drying process of the plants on the concentration of alkaloids and cytotoxicity of traditional Ayahuasca Tea

Introduction: Ayahuasca is a traditional psychoactive tea of Amazonian indigenous, used medicinal and spiritual purposes. Wide variation in the concentration of N,N-dimethyltryptamine (DMT), Harmaline (HRL), Harmine (HRM) and Tetrahydroharmine (THH) alkaloids in Ayahuasca has been reported worldwide. Objective: To evaluate the causes of variations in alkaloids concentrations of Ayahuasca prepared with fresh and dehydrated plants from different environments and determine the best drying method to plants according to alkaloids content and cytotoxicity of Ayahuasca tea. Material and methods: The environment interference on the alkaloids of the two species was evaluated in samples of Ayahuasca tea prepared with fresh plants. The most suitable drying process to the two species was evaluated in sample Ayahuasca tea prepared with plants submitted to drying under the sun conditions and five different temperatures in forced circulation oven. The concentration of the alkaloids determined by high performance liquid chromatography with UV-vis detector with diode array detection (HPLC-DAD). The in vitro cytotoxicity of Ayahuasca was evaluated in human keratinocytes cells (HaCaT) by colorimetric assay. Results: Environmental characteristics, preparation process and temperature of plants drying interfered on DMT, HRL, HRM and THH concentrations of Ayahuasca. No effect cytotoxicity was detected with relationship to psychoactive alkaloids in samples of Ayahuasca tea prepared with fresh or dried plants. Conclusion: Concentration of DMT, HRL, HRM and THH alkaloids in Ayahuasca are influenced by plants environmental. The most suitable drying process was obtained in forced circulation oven at 43 and 45°C to P. viridis leaves and B. caapi stems respectively. The Ayahuasca prepared with fresh or dry plants no showed cytotoxicity in human keratinocytes cells.
Experimental study of cadmium bioaccumulation in three Mediterranean marine bivalve species: correlation with selected biomarkers

Abstract An ecotoxicological study is presented, in which three marine bivalve species (Mytilus galloprovincialis, Callista chione, and Venus verrucosa) living in different habitats were studied for Cd bioaccumulation, under laboratory conditions. The bivalves, originating from a relatively polluted marine area of Greece (Saronicos Gulf), were exposed to 0.5 mg Cd L–1 seawater (4.4 μmol Cd L–1 seawater) for 5, 10, 15, and 20 days. Control animals were kept in metal-free seawater as well. Three or four different parts of the organisms (gills, mantle, body, digestive system) were examined for the bioaccumulation of Cd, as well as the levels of three biomarkers (metallothioneins, acetylcholinesterase, lipid peroxidation). A depuration experiment was also carried out. During the experiment, the initial levels of Cd in the control animal tissues either decreased or remained constant and low. The organisms exhibited different behavior regarding Cd bioconcentration and biomarker responses as well as tissue distribution of Cd. After the depuration period, significant amounts of Cd remained in the organisms’ tissues, much higher than the respective levels in control animals.
CLINICAL CHARACTERISTICS, LABORATORY ABNORMALITIES AND OUTCOME OF COVID-19 POSITIVE PATIENTS ADMITTED IN TERTIARY CARE HOSPITAL OF KARACHI

Background and Objective:COVID-19 is a corona virus disease infecting people worldwide. There are few local small-scale studies addressing this. We planned a study with good sample size to reveal clinical features and laboratory abnormalities in relation to ICU admission and mortality. Methods and Materials: This observational study was conducted at Dept. of Medicine Liyari General Hospital Karachi after ethical approval. The indoorconfirmed COVID-19 (PCR positive) patients (age>18 years) were included. Pregnant/lactating women, outdoor cases were excluded. Their demographic data, symptoms and signs,co morbidities, laboratory findings (blood complete picture, renal/liver function tests, inflammatory markers (i.e., CRP, ESR, ferritin, LDH, D dimers, troponins), area and duration of admission, disease severity, outcome as death or recovery were documented. Data was collected manually from record of the patients admitted from 15th March till 30th September 2020. The data was analyzed by SPSS software. Chi-square test applied with significant p<0.05. Results:Amongst879 patients 773(87.9%) were admitted in isolation wards whereas 106(12.1%) admitted in ICU. Mortality was 3.9% overall and average length of stay was 11 days. The mean age was 51.8+18.4 years. Most cases were male (65%) and > 50 yearsage (58.9%). Frequent co morbidities were diabetes(26.1%), dyslipidemia (23%), hypertension (19.9%) and ischemic heart disease (17.3%). Fever wasmost common symptom. Tachycardia, hypotension, anemia and lymphocytopenia wereassociated with ICU admission and mortality.Inflammatory markers were elevated in most of the cases but only LDH, ferritin and D-dimers were statistically associated with ICU admission and mortality. Conclusion:This study concludes that COVID-19 positive patients with age above fifty, tachycardia, hypotension elevated LDH, Ferritin, D dimers anemia and lymphocytopenia were associated with mortality and ICU admission.
Testbed for Security Testing ofSmart Contracts

Ethereum, one of the most popular decentralized blockchain-based platforms [1], manages cryptocurrency worth more than 40 billion US Dollars [2]. A lot of the money is controlled by autonomous programs, so called smart contracts. They are executed on the platform and everyone can call their functions; vulnerabilities are therefore easily exploited. The immutable nature of the blockchain sharpens the problem even further by prohibiting belated bug fixes. In fact, there were several cases where attackers were able to steal cryptocurrency worth several millions of US Dollar [3]. This emphasises the need of soundly testing a smart contract before deployment. Unfortunately, existing security analysing tools each cover a different subsets of vulnerabilities [4]. Moreover, even when they test for the same security issues, they often find different results. A solid test run should therefore contain several tools, which makes the whole procedure very laborious. For these reasons, we provide a testbed which runs on a virtual machine (VM) with several smart contract security analysing tools integrated. It does not only offer a command linebut also an intuitive web interface. Both interfaces allow the user to analyse his contract with all the underlying tools in a single step. Additionally, our testbed provides a detailed report for each of the tools’ test runs as well as an overview of the overall security issues the different tools found. Our evaluation shows that our testbed identifies significantly more potential security issues than each of the compared smart contract analysing tools individually does. Indeed, we found 92% of our analysed contracts as potentially being vulnerable, while even the most sensitive tool only flagged 76% of its successfully analysed contracts. Furthermore, we observed that occasionally, two tools testing for the same vulnerability, contradict themselves in more than 81% of the contracts successfully analysed by both tools.
Determinants of private domestic investment in Palestine: time series analysis

PurposeThis empirical paper aims to examine the impact of interest rate (IR) and political instability (POLINS) on Palestine's domestic private investment.Design/methodology/approachA set of econometric techniques of time series data are adopted to meet the study objectives. They include regression analysis, unit root tests, cointegration test, ARDL & Bound tests, VAR test and Granger causality test.FindingsThe study's primary results complement the neoclassical approach, which states that the IR is negatively associated with domestic private investment. The empirical results reveal that there is no long-run relationship. Also, there is no causality between domestic investment and lending rates. Accordingly, these findings alert policymakers to draw a series of steps to minimize the IR at a minimum to stimulate investment for improved economic growth and development.Practical implicationsThere is still no national currency in Palestine. The Palestinian Monetary Authority (PMA) is advised to set an appropriate ratio of the IR for the currencies-in-circulation in Palestine for boosting investment and economic development.Originality/valueThis paper provides new background information to both policymakers and researchers on the main determinants of investment in Palestine using econometric analysis. Accordingly, this critical issue is required to be examined in Palestine for stimulating investment.
Preparation of Pseudobohemite Coating on Metal Substrate

Pseudobohemite colloid used as the coating of monolithic metal substrate was prepared, and the effect of preparation conditions on the properties of colloid as well as the method of colloid coating was studied. The results indicated that the content of AlOOH and acidity of colloid solution are the key factors for colloid preparation which greatly affect the particle size, size distribution and stability of the colloid. When the AlOOH content was 4.5%～5.5% and [H +]/[AlOOH] was 0.08～0.1 (mole ratio), a stable colloid with small size and narrower size distribution was obtained, and it can be effectively used for coating the metam substrate. Besides the content of AlOOH colloid, the pretreatment of metal substrate also has an important effect on the amount of coating.
Effects of timing of nitrogen fertilizer application on responses by tropical grasses

Timing of nitrogen (N) fertilizer application can influence grass regrowth, so it is important to identify how tropical grasses respond to delays in applying fertilizer after defoliation. Our objective was to identify the effects of timing of N fertilizer application after harvest on the productive, morphogenic and structural characteristics of 3 tropical grasses: ‘Xaraés’ (Urochloa brizantha [Hochst. ex A. Rich.] Stapf cv. Xaraés), ‘Marandu’ (Urochloa brizantha [Hochst. ex A. Rich.] Stapf cv. Marandu) and ‘Tanzânia’ (Megathyrsus maximus [Jacq.] cv. Tanzânia). The experiments were performed in a greenhouse, in a completely randomized design, with 5 delays in applying N after harvesting (0, 3, 6, 9 and 12 days). Delaying fertilizer application did not affect the forage mass of Xaraés and Marandu palisade grass (7.4 and 7.8 g/pot, respectively). There was a linear decrease in number of leaves per tiller and leaf appearance rate, but tiller population density and phyllochron increased linearly as fertilizer application was delayed. Grass forage mass (12.2‒10.6 g/pot), number of leaves per tiller (3.1‒2.6 leaves/tiller) and forage accumulation rate (0.47 to 0.41 g DM/d) of Tanzânia guinea decreased linearly as N application was delayed, but tiller population density was unaffected (25 tillers/pot). Based on our results, N fertilizer should be applied to Tanzânia guinea grass pastures as soon as possible after harvest and certainly before 3 days, while there is not the same urgency with Xaraés and Marandu where fertilization could be delayed up to 12 days without significant detriment. These suggestions need to be tested in a field study before being recommended widely.
REMOVAL OF 4-CHLOROPHENOL FROM AQUEOUS SOLUTIONS USING GRAPHENE OXIDE NANOPOROUS ADSORBENT

n this study, graphene oxide was used as a nanostructured adsorbent with properties supposedly better than other common adsorbents to remove 4-chlorophenol from aqueous solutions. For this purpose, graphene oxide was initially synthesized using the Hummer's method and x-ray diffraction and scanning electron microscopy were employed to identify its morphology and structure. The variables involved in the absorption process (including 4-chlorophenol initial concentration, adsorbent dosage, and pH) were investigated based on the one- factor-at-a-time method. Eventually, the data were confirmed against the Langmuir and Freundlich isotherms. It was found that the adsorption process reached equilibrium in 20 minutes. A dosage of 0.4 g/L graphene oxide at pH=8 brought about 90% removal of 10 mg/L 4-chlorophenol within 5 minutes. The adsorption isotherm was described well by the Langmuir isotherm model and the values for R 2 and RL were recorded as 0.99 for and 0.34, respectively. Being a low cost and highly efficient process, the adsorption process using graphene oxide adsorbent may be recommended for the reduction and elimination of pollutants in the environment, especially those in aqueous solutions.
Evaluation of the physiological quality of quinoa seeds

The variations in seed quality and scarcity vigor studies have been limiting factors in crop establishment at different regions of its Andes origin. The present study aimed to evaluate the physiological quality of quinoa seeds, from cultivars of Brazil, Colombia and Ecuador. The research was conducted in the Seeds Technology Laboratory of the University of Brasilia, Brazil, through the tests of germination, hypocotyl and radicle length and accelerated aging test. Eighteen genotypes selected from different cultivars were evaluated using the F Test and Scott-Knotts. In addition, hierarchical cluster analysis was performed using the Ward method and Cluster analysis by k-means. The germination average was 80.81%; the hypocotyl and radicle length characteristics showed an average of 9.11 and 11.27 mm, respectively. The average germination after the accelerated aging test was 75.52%, with better results for the genotypes Piartal and Aurora. Quinoa genotypes showed variability in seed vigor, allowing determining differences in germination potential at high stress conditions. The application of methods developed for the analysis of quinoa seeds at 25°C and 4 days has been effective in screening for quality. Seed quality assessments in quinoa allow defining limits of tolerance to adverse conditions, facilitating selection in breeding programs. Key words: Accelerated aging test, Chenopodium quinoa, germination, selection, vigor.
Modified Gait Parameters at the Knee Joint During Midstance in Patients with Osteoarthritis

Background and Objectives: Sports medicine, orthopaedic and rehabilitation physicians use gait analysis and goniometry to evaluate and diagnose patients with neuro-musculo-skeletal diseases. Goniometry is a measuring method that shows the joint’s range of motion. Three-dimensional goniometry has been used in order to assess the patients in a kinematic manner, but they are not affordable, so, phone apps come handy to any orthopaedic or rehabilitation physician so we can have a clear image of the progress made by the patient after the rehabilitation program or should something happen and the patient cannot come to the facility, such as the Covid-19 pandemic, when some orthopaedic and most of the rehabilitation facilities have been temporarily closed. Midstance has been chosen as the moment of the gait evaluation in this paper since it has an important role in stability. The objective of this paper is to figure out if the measurements taken during midstance at the knee joint of the subjects can be statistically significant and used during usual examinations. Materials and Methods: Four groups of subjects: patients suffering from hip, knee, hip and knee osteoarthritis and a control group volunteered their participation, being asked to normally walk while their gait was recorded and uploaded into Angles App – a phone based videogoniometer. Results: Patients suffering from hip osteoarthritis have a higher knee angle on the right side than the ones suffering from knee osteoarthritis, hip and knee osteoarthritis and the control group. Female patients suffering from hip osteoarthritis also presented a more flexed knee than the ones suffering from knee osteoarthritis and the ones in the control group, the knee flexion presenting itself as a compensation mechanism. Conclusion: Video goniometry can help us make an orthopaedic, rehabilitation or neurology database for each assessment with constant updates of the evolution of the osteoarthritis patient’s treatment.

Walaa M. Abdelaziz, Taghreed M. Farahat, Hala M. Shaheen, Mohamed A. Gaber, Nora A. Kkalil 1 Family Medicine Department, Faculty of Medicine, Menoufia University, Egypt 2 Dermatology and Andrology Department, Faculty of Medicine, Menoufia University, Egypt Abstract: Background: Acne is chronic inflammatory disease with formation of papules, pustules, and nodules. Vitamin-D is fat soluble vitamin with immunomodulatory function, helps reducing inflammation. Objectives: assess frequency of serum vitamin-D deficiency among acne vulgaris patients and the effect of vitamin-D supplementation on acne grading. Method: the study was conducted on two phases, phase I was a cross-sectional study included measuring serum vitamin D level for 80 acne patients attending dermatology clinic at Menoufia University Hospital. Phase II was an interventional case control study where studied acne patients with vitamin-D deficiency (66 patients) were randomly divided into two groups; one group (33 patients) were treated with free Oral vitamin-D 2000IU/ tablet daily for two months in addition to regular acne treatment. The other group (33 patients) received traditional treatment for acne without vitamin-D supplementation and both groups were followed up clinically for two months. Results: frequency of vitamin-D deficiency among studied patients was 82.5%, there was statistically significant relation between vitamin-D deficiency and severity of acne as 27.3% and 9.1% of them had grade 3& 4 acne respectively versus 7.1% and zero% among acne patients with normal vitamin D. Vitamin-D deficiency is significantly prevalent among female patients (98.4%), there was significant improvement in acne grading after vitamin-D supplementation. Conclusion: There is a significant relation between vitamin-D deficiency and severity of acne vulgaris and vitamin -D has a good role in management of acne. So. It is recommended to evaluate the serum level of vitamin D in acne patients and provide vitamin D supplementation to vitamin D deficient patients beside topical treatments for acne.
MIX-and-Match or Mismatch? Exploring Older Adults’ Perspectives About Zumba Dance and Its Potential Utilization for Dual-Task Training

Background: Despite the popularity of Zumba in several countries, research is scarce about its impact on older adults. Meanwhile, the integration of cognitive tasks with physical exercises, known as dual-tasking, is an evolving strategy to facilitate activities for older people. This study investigated the perceptions of older adults regarding Zumba and the potential of implementing it in a dual-task program. Methods: We conducted a qualitative-descriptive research involving 44 Filipino older adults from August to November 2020. Content analysis was employed to analyze the data. Results: Four themes were identified – moving towards match or mismatch; balancing benefits with burdens; dual-tasking as innovative yet potentially challenging; and overcoming barriers with enablers. While Zumba is an inclusive and beneficial activity, individual and contextual limitations could hinder its suitability for older people. Dual-tasking in Zumba was also recognized as an innovative approach, although challenges should be addressed to promote its utility. Several strategies could support the design of these programs in communities. Conclusions: This is the first study to explore older adults’ perceptions towards Zumba and its potential utilization as a dual-tasking program. Findings could guide the implementation of appropriate Zumba and dual-tasking activities that seek to integrate cognitive and physical training for older adults.
Worse is worse and better doesn't matter?: The effects of favorable and unfavorable environmental information on consumers’ willingness to pay

Increasing consumers’ willingness to pay (WTP) for environmentally friendly products is a key challenge for sustainable development in market economies. Still, how consumers react to favorable and unfavorable environmental information of different quantitative extents is largely unknown. This research therefore uses prospect theory and competing theoretical foundations to derive pertinent hypotheses and test them by using a multi‐level structural equation model. The analysis draws on a survey‐based experiment conducted among a representative sample of the German population. Results confirm key assertions of prospect theory. The negative effect caused by unfavorable product carbon footprint information on WTP is stronger than the positive effect caused by respective favorable information. Besides this negativity bias, consumers tend to generally reward or punish deviations of a product's environmental performance from industry average instead of consistently accounting for the size of these deviations. From a sustainable development perspective, the observed patterns highlight a problematic contrast between the need for substantial environmental improvements and limited market incentives for companies. Consequently, political intervention is needed to introduce negative labeling, raise consumers’ reference points, set minimum industry standards, and subsidize companies for radical improvements.
