Authors: Ismail Mohammad Hafiz , Razak Tajul Rosli
Published: December 2020

This study investigates the potential of Deep Learning techniques, specifically LSTM networks, in forecasting Kijang Emas future value over a long period. Six LSTM models comprising of Simple LSTM, Bidirectional LSTM, and Stacked LSTM architecture were built and trained against a 15-year historical price data for Kijang Emas. The models’ performance was then measured against ARIMA (5,1,0) as a baseline reference and evaluated against the RAE, MSE and RMSE metric. The results revealed that LSTM networks models performed well in forecasting Kijang Emas price based on the test dataset where the average RMSE was between 49.9 to 50.3 while the Bidirectional LSTM was found to exhibit better performance as compared to the other LSTM models.
The Impact Of Covid-19 On Islamic Banking In Indonesia During The Pandemic Era
Authors: Omar Zulfikar
Published: December 2020

The impact of COVID-19 on Islamic banking can be analysed into three possible risks, such as financing risks, impairment of assets, and tightening the profit-sharing system. Compared to conventional banks, Islamic banking is more flexible in meeting the economic crisis caused by the COVID-19 pandemic. Basically, the national banking system had predicted trouble due to the COVID-19 epidemic. On the other hand, Islamic banks are at an advantage with the theory of profit-sharing, thus increasing its effectiveness in dealing with crises. Islamic banks’ dominance throughout these challenging times is undoubtedly an excellent opportunity to strengthen their market share. Besides, Islamic banks can face risks, such as providing loans, deteriorating asset quality, and tightening profit sharing. Therefore, Islamic banks must understand these risks to ensure their plans during the COVID-19 pandemic. Admittedly, performing restricted expansion into the digital share is a challenging decision that should be practised by Islamic banks. In view of the recent pandemic, this study aimed to analyse the three risks faced by Islamic banking in Indonesia.

Authors: Mohamed Mas Azira , Wee Yu Ghee
Published: December 2020

Online shopping is becoming increasingly important in the current era, rendering comprehension of consumer online shopping habits crucial. This notion rings true in the context of users and companies alike, thereby emerging as a big concern for e-commerce managers and researchers. One may assume that only by understanding the factors influencing consumer buying intentions for fashion items online will companies be better-positioned for meeting consumer needs. In this analysis, the relationship between customer online purchasing intentions and selected factors was investigated, specifically consumer innovativeness, fashion innovativeness, and fashion involvement. Quantitative research was implemented in the process, involving fashion online shoppers in Malaysia as the respondents after being selected via quota sampling from the ten most popular fashion shopping websites in Malaysia. The statistical method of Partial Least Square – Structural Equation Modelling (PLS-SEM) was then employed for the proposed model testing. The findings subsequently revealed the positive effects of consumer innovativeness, and fashion involvement on online purchase intention, whereas any significant relationship between the variable with fashion innovativeness was absent. However, this analysis was conducted in Malaysia; therefore, the results could be different if tested in other countries. Hence, similar studies related to fashion online purchase intention should be replicated in other Asian countries in the future.
Illusory Control and Well-Being in a Non-Clinical Sample
Authors: Todor Ioana
Published: December 2020

A perceived sense of control over the environment is one of our basic needs. People’s need of control is a survival mechanism and a factor of human progress. Perceived control refers to the individual’s beliefs about the controllability of a situation and about the degree to which she/he has the skills and abilities necessary to obtain a desired outcome. Illusion of control is people’s tendency to overestimate their abilities to control the events. According to Taylor and Brown (1988), illusion of control is one of the people’s positive illusions, enhancing their emotional comfort and sense of security, in a word which is perceived more familiar and predictable than it is in reality. The general aims of this study are: 1) to investigate the presence of unrealistic perceptions of control in a sample of Romanian students and 2) to investigate a possible correlation between illusory control and well-being. The results confirm people’s general tendency to overestimate their ability to control the events. A direct correlation between illusion of control and well-being could not been demonstrated. The role of illusory control as an adaptive mechanism is discussed according to the available data.
ALGORITHM OF COMPLEX URBAN METEOROLOGICAL ASSESSMENT
Authors: Shevchenko О.
Published: December 2020

Determining the main patterns influencing the formation of urban meteorological transformations in cities, establishing mechanisms of interaction between components of the urban environment, development of methods, approaches, and preparation of algorithms for obtaining objective information about the urban environment are very important and urgent tasks which determine the development of urban meteorology as a science and have important practical significance. The aim of this work is the development of the algorithm of complex urban meteorological assessment for objective identification of transformations in the atmospheric environment of big cities. The methodological basis of the research is the concept of interaction of urban meteorological components of the city. The results of the latest meteorological studies of urban areas are systematized in this work. It is shown the close relationships between the urban meteorological components (microclimate, bioclimate, air pollution, and climate change and vulnerability to it) and their significant influence on the formation of each other. The necessity of the development of a complex urban meteorological assessment algorithm is substantiated and such an algorithm is offered. The algorithm consists of four basic stages and one which can be realized optionally. The assessment of microclimatic features of separate sites of the territory should be carried out at the first stage. The second stage of the assessment should be the study of the specific urban bioclimate, as the UHI existence, wind speed reduction and associated changes in urban energy balance within the city lead to the formation of specific bioclimatic conditions in urban areas. The third stage of the assessment should be devoted to the evaluation of air pollution levels in the urban environment. The city’s climate change vulnerability assessment should be done at the fourth stage. Features of realization of each stage are described in detail.
STUDENT-CENTERED CLASROOM ASSESSMENT: PERCEPTION AND NEW METHODS
Authors: Popokammenou Irini-Renika
Published: December 2020

One of the important roles and responsibilities of teachers is to conduct assessment to assess students’ progress. The implementation of alternative assessment methods can be frustrating and rather difficult for teachers. This paper discusses teacher and student perceptions on using alternative assessment. It focuses on how young learners of English perceived three different alternative assessments: peer-assessment, conferencing and the use of students’ drawings as assessment materials. The data sources comprised classroom observations, interviews with teachers and written comments from students. Analysis of the data provided insights on how teachers choose assessment techniques in A1 and A2 level classes. Teachers’ perceptions on the specific assessment methods are discussed. The written comments from students identified how students perceived the combination of the assessment methods employed by teachers and which assessment method they favored. The results show that teachers and students have positive perceptions on alternative assessment. Students’ needs and age are important factors for selecting assessment methods and individual needs must be taken into consideration when choosing alternative assessment methods. This paper highlights the importance of alternative assessment in A1 and A2 level classes since it can improve instruction. Results on the drawings used in the study as assessment materials indicate that students value personalized assessment. Alternative assessment can be a vital component in educators’ efforts to improve education.

Authors: Blumer Sigalit , Peretz Benjamin , Yukler Native , Nissan Sagit
Published: December 2020

Purpose: Dental student’s dental anxiety may negatively affect patient’s attitude towards dental treatment. We evaluated dental anxiety among dental students in different clinical stage of their studies. We assessed the student’s anxiety prior to treating patients. Study design: A cross-sectional study. Fourth to sixth-year dental students completed questionnaires containing: 1) Dental Anxiety Scale (DAS); 2) Dental Fear Survey (DFS); and 3) visual analogue scale questions relating to the student’s anxiety when performing dental treatments in children and adults. Results: 124 dental students completed the questionnaires (mean age, 26.4±3.1 years, 59.7% women). Average DAS in the study population was 7.55±2.15 with similar scores observed across the years. Average DFS score was highest among fourth-year students (1.62±0.65) and lowest among sixth year students (1.36±0.32). DFS scores decreased as the students progressed through the clinical years (p=0.059). The students’ average anxiety scores prior to treating children were significantly higher than the anxiety scores prior to treating adults (3.82±2.42 vs. 2.67±1.9, p<0.001). Fifth-year students had significantly higher anxiety scores prior to treating children and adults compared to fourth and sixth-year students. Conclusion: Dental anxiety among dental students is relatively low and decreases gradually as they progress through the clinical years. Anxiety prior to treating patients, particularly children, is at its highest just before starting to treat patients for the first time. As dental students are future healthcare providers, it is important that they learn techniques to help them manage their own dental anxiety and fear as well as deal with anxiety related to treating patients.

Published: December 2020

Objective: To determine the maximum occlusal bite force (MOBF) of the complete spectrum of dental caries in first permanent molars (FPMs) in children aged 7–9 years. Study design: A cross-sectional study was conducted on 123 children. The evaluation of the caries spectrum of FPMs was carried out using the Caries Assessment Spectrum and Treatment index (CAST). The MOBF was measured in the FPM region using the portable occlusal force gauze. Independent sample t-test and one-way analysis of variance test were performed to compare MOBF with CAST scores of FPMs. Based on the CAST scores, FPMs were categorized into three groups, group 1: healthy (score 0, 1, 2), group 2: premorbid (score 3), group 3: morbid (score 4, 5). Results: A significantly lower MOBF was observed (167.56 N ± 49.77) in the morbid stage (group 3) than in the premorbid stage (group 2: 291.57 N ± 56.64), and healthy (group 1; 320.93 N ± 54.23). Intergroup comparison also revealed that FPMs in the healthy stage was associated with a higher bite force compared to those in the premorbid and morbid stages (p<0.001). Conclusions: The mean MOBF decreased with the progression of the caries spectrum of FPMs in early permanent dentition.

Published: December 2020

Objectives: To compare the prevalence of parafunctional habits, erosive tooth wear and occurrence of tooth injuries among children being under the care of Social Welfare Centre and children treated in the Department of Children’s Dentistry of the Medical University of Warsaw. Study design: The study contains environmental and medical interviews, record-based analysis and clinical examination. Parafunctional habits were rated on the base of dental interviews and clinical examinations. The occlusal surfaces were evaluated by visual examination using modified tooth wear index (TWI). Tooth injuries were reported from a medical interview labeled using Andreasen classification. The consent of the bioethics committee and guardians of children participated in the study was obtained. Results: The study involved 782 patients, including 404 children from dysfunctional families (average age 11,4 ± 3,7) and 378 from ordinary families-control group (8,53 ± 3,92). In the study group we observed higher prevalence of erosive tooth wear (44,66% vs 18,02% p=0,000), dental trauma (9,4% vs 3,44% p=0,001) and a presence of parafunctional habits (67,8% vs 20,4 % p=0,000). Conclusion: The occurrence of parafunctional habits, erosive tooth wear and tooth injuries may be an indicator of domestic violence and a component of maltreated child syndrome.

Authors: Lu Wei , Qi Gang-gang , Li Xiao-jun , He Fu-ming , Hong Bo
Published: December 2020

Background: Plasma cell granuloma (PCG) is a rare benign pseudotumorous proliferation of unclear etiology that is mainly situated in the lungs. Gingival PCG is an even more peculiar lesion that usually occurs in middle-aged or elderly individuals and clinically manifests as a solitary entity. Case report: A 15-year-old male with no underlying medical conditions presented with multiple gingival masses in the right maxilla, which were initially thought to be epulis. The lesions were resected completely and the excisional biopsies sent for histological examination. Immunohistochemical (IHC) stain revealed dense polyclonal plasma cell infiltration with positive expression of both kappa and lambda light chains, confirming a diagnosis of gingival PCG. Subsequently, the affected gingiva healed uneventfully, with no sign of recurrence over 2 years of follow-up. Conclusions: The present report depicts an extremely unusual case of gingival PCG occurring in a juvenile with multiple lesions, which is worth attention in clinical pediatric dentistry. Excisional-biopsy and histological investigations are imperative for a confirmative diagnosis and to exclude potential aggressive conditions. Complete resection of lesions seems to be a valid treatment, while long-term clinical follow-up is still needed.
Forms of In-House Mutual Assistance in Advocacy: History and Modernity
Authors: Yartykh I. S.
Published: December 2020

In this work, the author emphasizes that interpersonal solidarity presupposes the possibility of overcoming various crisis phenomena using the potential of collectivism inherent in free associations. Based on this, the author concludes that the need for the existence of the legal profession is determined not so much by law, but rather by the very nature of man as a social being. The advocacy as a public institution has two goals: to provide a public function to protect the rights and freedoms of sufferers during the administration of justice by the state and to ensure the existence of the social stratum through the implementation of the principle of corporatism enshrined in the law. The principle of corporatism presupposes organizational unity, corporate solidarity, and mutual assistance. The paper examines the history of the emergence of in-house institutions of advocacy solidarity by the example of the "organization of mutual assistance funds" of the St. Petersburg and Moscow councils of attorneys. The author analyses if the modern Russian legislation possesses organizational forms that can become the basis for the organization of modern institutions of mutual assistance of advocates.

Infinity and Transcendence: Husserl, Heidegger and Tengelyi
Authors: Belousov Mikhail
Published: December 2020

Laszlo Tengelyi’s phenomenological project, as presented in his book “World and infinity. To the problem of the phenomenological metaphysics”, published posthumously, is founded on the idea of the infinity of the world. In rehabilitating the husserlian thesis of the infinity as constitutive feature of the worldly experience, Tengelyi departs from the phenomenology of the finitude, which goes back to Heidegger. The article analyzes the origins of the infinity/finitude dilemma in transcendental phenomenology of the world in Husserl, Heidegger and Tengelyi. It demonstrates that the dilemma is rooted in the ambiguity of the phenomenological concept of transcendence. On the one hand, the transcendence is interpreted as the essential openness of the experience, which renders it infinite. On the other hand, the openness is constituted by horizon as the finitude of the experience.
László Tengelyi: Leben und Werk
Authors: Schnell Alexander
Published: December 2020

This introduction provides a brief overview of L. Tengeli's life path and philosophy. The author identifies three main questions of his philosophy, which are the question of life-history, the question of experience and the question of the phenomenological metaphysics. According to the central thesis of the introduction, Tengeli is the characteristic representative of modern phenomenology, because in his philosophy we find all those distinctive features which are peculiar to phenomenology in the 21st century: problem of transcendentalism, problem of phenomenological metaphysics, and productive address to history of philosophy.

Published: December 2020

Advanced material such as composite material, metamaterial, nanomaterials and smart materials plays a significant role in degree of performance of any system as compared to conventional material and hence, they are commonly used in diverse applications such as aerospace, medical devices, sensor detection, smart solar application etc. Metamaterial is one of such artificial sub-wavelength materials to exhibit electromagnetic and optical properties that surpass or complement those accessible in nature. In this research paper, three structure of metamaterials are simulated for the solar application as an absorber to increase solar efficiency as well as to increase negative refractive index to represent wave propagation in different directions. From this study it can be concluded that all the three materials have reached maximum point of absorption in a narrow bandwidth and it is possible to obtain transverse magnetic wave if the materials are stacked. These materials can be used as frequency detector for THz applications.

Damage Quantification of Frame-Shear Wall Structure with Metal Rubber Dampers under Seismic Load
Authors: Zhao Yagebai , Zhang Liangquan
Published: December 2020

The seismic load can bring serious damages to the coupling beams and frame beams in the frame-shear wall structure. Such damages can hardly be repaired, causing functional loss to the structure. One of the best ways to consume seismic energy input, rationalize the damage mode of structure, and prevent serious damages to the main components is to install metal rubber (MR) dampers materials in the frame-shear wall structure. Based on Park and Ang’s damage model, this paper presents pertinent formulas of damage indexes, and uses them to quantify the failure mode. Then, the correspondence was established between damage level of the target structure, reasonable damage mode, and damage index. Finally, two ABAQUS models of an 18-floor frame-shear wall structure were constructed: an uncontrolled structure (traditional frame-shear wall structure) and a controlled structure (frame-shear wall structure with MR dampers). Through comparative analysis, the characteristic parameters of the damper were determined for the reasonable damage mode, and the failure mechanism of the target structure was identified accurately under seismic load.

Hormone therapy for postmenopausal women
Authors: J. V. Pinkerton
Published: December 2020

Hormone therapy is recommended for relief from hot flashes or night sweats in women younger than age 60 years or those who entered menopause within 10 years of seeking treatment. Hormone therapy also can reduce bone loss and the risk of fractures; offer a potential cardioprotective benefit; and alleviate the genitourinary symptoms of menopause, including dysfunction of the bladder and irritation of the vagina and vulva.For women with early menopause without contraindications, hormone therapy is recommended until at least the average age of natural menopause. Observational studies suggest that the risk of thromboembolism and stroke is lower with transdermal therapy than with oral hormone therapy. Compounded bioidentical hormone therapies that have not been approved by the Food and Drug Administration are not recommended owing to safety concerns. Hormone therapy is not recommended for primary or secondary prevention of coronary heart disease or dementia. Nonhormone therapies that have been shown to reduce hot flashes include low-dose selective serotonin-reuptake inhibitors and serotonin–norepinephrine reuptake inhibitors, gabapentinoids, weight loss, hypnosis, and cognitive behavioral therapy. For women with only genitourinary symptoms, local vaginal hormone therapies are recommended.The treatment is not without its risks, including concerns about cognitive decline and breast cancer. More research is warranted, to determine the long-term benefits and risks of menopausal hormone therapy, to gauge the effects of prolonged use in women initiating therapy close to menopause, to inform the timing of and approach to hormone therapy discontinuation, and to answer additional unknowns. As scientists work to address these questions, technology can help identify women likely to benefit from hormone therapy. The MenoPro mobile app, backed by the North American Menopause Society, provides a free algorithm to flag the strongest candidates.
Inositols in reproductive medicine
Authors: O. M. Nosenko  , O. V. Novikova
Published: December 2020

The article presents literature data on the role of inositol and its derivatives in human body, results of the myo-inositol (MI) use in gynecological diseases, treatment of female and male infertility, including in cycles of assisted reproductive technologies, in the prevention of gestational and perinatal complications. It has been shown that the inability to adequately synthesize or metabolize inositol can contribute to disturbances in the transmission of intracellular signals, disturbances in the activity of insulin signaling cascades, development of insulin resistance and hyperinsulinemia, which cause abnormal steroidogenesis in the gonads and metabolic disorders.The concept of  “D-chiro-inositol paradox” is highlighted, according to which women with polycystic ovary syndrome are characterized by increased epimerization of MI to D-chiro-inositol, depletion of MI reserves and low oocyte quality. Prescribing biologically active supplements with MI and folic acid for pregnant women reduces the likelihood of threatened abortion, preeclampsia, placental dysfunction, gestational diabetes mellitus, diabetic fetopathy, malformations, oxidative stress in the fetus.Experience has also been accumulated about myo-inositol use in andrology: it plays a decisive role in osmoregulation of seminal fluid and, as a consequence, increasing the progressive sperm motility and speed, increasing the mitochondrial sperm potential, improves libido and potency, helps to increase the endogenous testosterone, and normalizes the men’s hormonal balance. Inositol is a synergist of folates and other B vitamins and significantly potentiates their effect on the human body; it is the basis for the advantages of using combined biological supplements such as Miofolic® and Miofolic® MEN in the clinic for female and male reproduction. Harmonious use of all possible reserves of micronutrient support for the preconception and gestational period with the use of biologically active supplements of MI in combination with folic acid and vitamin B12 is a promising preventive and therapeutic agent in supporting of reproductive system, embryo development, neuroprotection of the fetal brain, ensuring the activity of signaling cascades insulin.

Authors: O. H. Boichuk  , D. Y. Hulii
Published: December 2020

Objective of the study: improvement of diagnostic methods for pregnant women with tumor-like formations and ovarian tumors.Materials and methods. 60 pregnant women were examined and divided into 3 groups: group I – 28 pregnant women with ovarian tumors who underwent surgical treatment during pregnancy; group II – 21 women with ovarian tumors who underwent surgical treatment at various times after spontaneous delivery; group III (control) – 11 women with a normal course of pregnancy without ovarian tumors.Doppler ultrasound was performed on a mandatory basis at the screening time, and as well as needed. MRI was performed in 8 diagnostically difficult cases. In the II trimester of pregnancy at 12–24 weeks in 49 women with ovarian tumors tumor markers were determined: CA-125, HE-4, β2-microglobulin, transthyretin, transferrin and apolipoprotein A-I, and combined ROMA and RMI indices.Results. The analysis showed the characteristic echographic signs of most ovarian tumors in pregnant women. The overall accuracy of ultrasound in determining the ovarian tumor structure at the outpatient level was extremely low and amounted to 21.8%, in a specialized medical institution it was 79.2%. In the diagnosis of mature teratomas were found MRI sensitivity and specificity of 100%, less diagnostic value (sensitivity 91.7%, specificity 96.9%) was typical for endometrioid ovarian cysts. MRI efficiency in detecting malignant potential (borderline and malignant tumors) was quite high (sensitivity 80.0%, specificity 97.4%).The presence of any ovarian tumor, except for mature teratomas, was accompanied by a significant increase in CA-125 level. The strongest correlation was found for RMI index and CA-125 and HE-4 tumor markers.Conclusions. Doppler ultrasound and MRI are complementary highly informative methods for diagnosing ovarian tumors in pregnant women. Tumor markers used for the differential diagnosis of benign and malignant tumors outside pregnancy (CA-125, HE-4, apolipoprotein A-I, transferrin, transthyretin, β2-microglobulin) do not have a high enough diagnostic value in ovarian tumors in pregnant women, therefore their tests should be supportive.

Published: December 2020

Purpose of the study – to analyze the structure and morbidity patterns of control of sexually transmitted infections (STI) for the period from 2014 to 2019 in accordance with data collected by the Statistical Department of the MoH of Ukraine.Materials and methods. It was analyzed data on the STI incidence in entire population, namely from 15 years to 60 years and older, female and male, the prevalence of diseases depending on the place of residence (city or village) was performed. Particular attention is paid to the STI analysis in women and men of reproductive age. Data from the temporarily occupied territories of the Autonomous Republic of Crimea, Donetsk, Luhansk Oblasts and the city of Sevastopol are missing.Results. The incidence of STI over 5 years (2014–2019) changed as follows: syphilis decreased by almost 1.5 times (from 8.65 to 6.01 per 100,000), but remained significantly high at reproductive age (13.25 vs. 9.56 per 100,000), men are more susceptible. Significant reduction in the incidence of gonorrhea from 14.85 to 7.97 per 100,000, by 1.8 times, but among men and women of reproductive age 2.5 and 3 times more (37.26 and 24.12 per 100,000), men are more susceptible. Cases of chlamydial infection decreased from 53.02 to 32.54 per 100,000, and were more common in the age group of 18–39 years, men are more susceptible. The incidence of trichomoniasis decreased by 1.6 times from 128.77 to 79.79 per 100,000. The incidence of trichomoniasis was the highest at reproductive age – 320.87 in 2014 and 210.78 in 2019 per 100,000, more often found in women. The incidence of urogenital mycoplasmosis also decreased over 5 years from 71.88 to 51.94 per 100,000, by 1.3 times, women are more susceptible. The urban population suffers from STI 2.5–3 times more than the rural population.Conclusion. STI is a national health problem in Ukraine. Prevention, early diagnosis and modern adequate treatment of a couple with STI are the key to reducing the incidence of male and female infertility.
A comparative study of combination of Myo-inositol and D-chiro-inositol versus Metformin in the management of polycystic ovary syndrome in obese women with infertility
Authors: Sujana Thalamati
Published: December 2020

Polycystic ovary syndrome (PCOS) is a symptom complex associated with increased amounts of circulating androgens in females, increased insulin resistance and obesity. The drugs, Myo-inositol, D-chiro-inositol and Metformin, which are insulin sensitizers, are very helpful in taking care of one of the key components of PCOS that is insulin resistance. Myoinositol and D-chiro-inositol are isomeric forms of inositol that have insulin-like properties, acting as second messengers in the insulin intracellular pathway; both of these molecules are involved in the increasing insulin sensitivity of different tissues to improve metabolic and ovulatory functions.This study was done to compare the effects of combination of Myo-inositol and D-chiro-inositol with the use of metformin on clinical and biochemical profile in PCOS.Methods. A prospective, randomized, comparative study was conducted on 200 patients. The patients were randomly assigned into the two groups of 100 each. Group A receiving Tab. Myoinositol 550mg twice daily and Tab. D-chiro-inositol 13.8mg twice daily and Group B receiving Tab. Metformin 500mg thrice daily. The patients were assessed by menstrual cycle regulation, hirsutism score (Ferriman Gallwey), fasting and postprandial glucose and insulin levels, serum dehydroepiandrosterone levels, serum free testosterone levels and serum luteinizing and follicle stimulating hormone ratio.Results. In both the groups there was significant improvement in all the above mentioned parameters, however the group with Combination of Myo-inositol and D-chiro-inositol had statistically significant improvement over the Metformin group.Conclusions: Combination of Myo-inositol and D-chiro-inositol and use of metformin, significantly improved insulin sensitivity in PCOS women. But combination of Myo-inositol and D-chiro-inositol was effective in controlling the hormonal profiles (luteinizing/follicle stimulating hormone ratio and free testosterone) when compared to Metformin.

Psychotic disorders are a group of severe mental disorders that can remarkably affect brain functions by altering beliefs and perceptions. There are different types of psychotic disorders,including schizophrenia, delusional disorder, paraphrenia, etc. The symptoms of a psychotic disorder include delusions, mood swings, difficulty concentrating, unusual behavior, alteredfeelings, and so on. Symptoms may vary from person to person and change with time. Antipsychotic drugs and psychotherapy can be used in the treatment of psychotic disorders.In this case report, we describe a 39-year-old woman who suffered from methamphetamine-induced delusional parasitosis.

Published: December 2020

One of the critical factors with a broad impact on health is obesity. Besides its cardiovascular comorbidities, obesity’s probable association with hypogonadotropic hypogonadism inmen will be discussed in this article by reporting a severely obese boy, presenting with the absence of secondary sexual characteristics and hypertension. The hypothalamus-pituitary-gonadal axis can be influenced by several mechanisms at different levels of the axis. Some of these pathophysiological mechanisms, related to our case are explained to explore the association of obesity with reproductive disorders. Adipose tissue plays a prominent role in the metabolism of hormones that are secreted by other glands. Obesity as a preventable risk factor is valuable to be researched, to decrease the burden of its morbidity and mortality. Thus more studies should be done in the future to determine the complex network of factors contributing to hormonal imbalances seen in obese people.

Published: December 2020

Background and Objectives: Waste water from abattoirs could harbour bacteria some of which are pathogenic. Therefore, this study aimed to assess the quality of wastewater from some abattoirs in Ilorin, Nigeria.
Materials and Methods: The counts of viable bacteria, total coliform, faecal coliform, enterococci, S. aureus, P. aeruginosa and Salmonella/Shigella spp. of the wastewater was determined using selective media. The sanitary condition appraisal, antibiotic susceptibility test and plasmid profile of the isolates were assessed using standard methods.
Results: The highest count of viable bacteria and total coliform obtained were 9.0 × 107 and 3.0 × 107 CFU/ml respectively. Faecal coliform and enterococcal count had the same highest value of 3.0 × 105  CFU/ml. The highest count of pathogenic bacteria: Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella spp. were 2.5 ×  108, 1.9 ×  107  and 3.0 × 104 CFU/ml respectively. The abattoirs sanitary scores ranged from 28.6-57.1%.  The isolates showed multiple antibiotic resis- tance (MAR) index ranging from 0.5-1.0. Plasmid curing with 0.1 mg/ml of acridine orange solution led to reduction in the MAR index of most of the Gram negative bacteria. Pseudomonas stutzeri was susceptible to all the antibiotics while Proteus vulgaris was resistant to all the antibiotics after curing. Most of the Gram negative bacteria isolated belong to the families Enterobacteriaceae and Pseudomonadaceae while the Gram positive bacteria belong to the families Staphylococcaceae, Enterococcaceae and Streptococcaceae.
Conclusion: It was concluded from this study that wastewaters from the abattoirs were contaminated by bacteria with high MAR index. Most of these bacteria borne their antibiotic resistant factors in their plasmid.
Effect of iron and silver nanoparticles on coenzyme Q10 production by Gluconobacter japonicus FM10
Authors: Moghadami Foozieh , Hosseini Ramin
Published: December 2020

Background and Objectives: Coenzyme Q10 is an anti-aging agent whose demand is increasing progressively. There are various strategies used for increasing coenzyme Q10 production by microorganisms. In this study, for the first time, we investigated the effect of iron oxide and silver nanoparticles on coenzyme Q10 production by Gluconobacter japonicus FM10.
Materials and Methods: In the first step, a preliminary experiment was set and carried out to obtain the minimum inhibitory concentrations of the nanoparticles on the strain FM10. Then the sub-MIC concentrations were used to investigate their effect on coenzyme Q10 production in the stationary and exponential phases of the growth, separately.
Results: The results showed that coenzyme Q10 production increased in the presence of the iron oxide and silver nanoparticles. The silver nanoparticles induced 1.9 times higher coenzyme Q10 production. The highest level of coenzyme Q10 was induced when the silver nanoparticles were added to the culture medium at the stationary phase.
Conclusion: This should be noticed that so far nanoparticles have been considered as antibacterial agents, rather than being considered to cause probable beneficial effects on the induction of useful products in the microbial world. In this regard, their potential for increasing coenzyme Q10 production has received no attention. However, our present results showed that the nanoparticles can be used to increase the production efficiency of coenzyme Q10 in Gluconobacter.
