Teachers' blended teaching ability refers to the ability of teachers to use both online and offline occasions and scenes for blended teaching. At present, the blended teaching ability of teachers in China University of Geosciences (Beijing) is still insufficient, which affects the effectiveness and quality of blended teaching. This paper puts forward the improvement mode of informatization teaching ability under “double blended learning-driven”, that is, to transfer to the "blended" teacher teaching through the "blended" teacher training. Starting from the inscapes and existing problems of teachers' blended teaching ability in universities and colleges, this paper creates a flexible training mode of teachers' blended teaching ability in universities and colleges, taking the major of Business Administration as an example, giving an effective way to improve teachers' informatization teaching ability, so as to provide reference for the university to design and optimize the mode of teacher training.

Intracranial epidermoid tumors are inclusion tumors of the central nervous system. They are congenital neoplasms that grow through desquamation of keratin, cholesterol and cellular debris. They cause mass effect and gradual development of neurological symptoms. Here we present a case of a 65 year old lady who presented with new onset seizures, CT scan suggesting a low grade cortically based neoplasm and a diagnosis of epidermoid cyst was made from histopathological sections.

Plasma cell leukemia is one of the most aggressive and rarest forms of plasma cell dyscrasias. It can arise from a leukemic transformation of multiple myeloma or can be primary and the prognosis is very poor. We present the case of a 68 year old male who presented to our hospital with features of acute renal failure. He was diagnosed as a case of Plasma cell leukemia and was treated with chemotherapy. However his condition deteriorated and he died 2 weeks after diagnosis. The recommended treatment of plasma cell leukemia is aggressive chemotherapy followed by stem cell transplantation. However, once diagnosed, the prognosis is very poor.

Parotid gland sialolith is a very rare condition with symptoms of pain and infection in affected individuals (4- 10%) caused due to any systemic diseases, bacterial infections, medications, abnormality in the secretion of gland etc. Here reporting a case of 28 year old male patient having calculi in his left parotid gland. Routine radiographic procedures and advanced modalities like ultrasonography, cone beam tomography confirmed the diagnosis then it is removed surgically without major complications.

Wound healing involves a complex cascade of events, ordered and complex, involving many types of cells, which are driven by the release of soluble mediators and signals able to influence these circulating cells and cause them to home back to damaged tissues. Platelets proved themselves to be an important cells regulating haemostasis phases through the vascular occlusion and facilitating fibrin clot formation. This fibrin scaffold, devoid of any cytotoxic property, is obtained from 9ml of patient’s blood, after centrifugation performed with a centrifuge and the use of gel-free vials; it contains a variety of blood cells- including platelet, B and T lymphocytes, monocytes, stem cells and neutrophilic granulocytes- other than growth factors. L- PRF (leukocyte-PRF) and its derivatives (A-PRF, i- PRF and so on). There is an abundance of literature on the use of injectable PRF (i-PRF) on dental implants with successful results. Therefore, in this case report i-PRF was used as regenerative alloplastic material for an infrabony defect. At 9 months follow-up, there was a reduction in pocket depth and radiographic evidence of bone fill was also noted.

The emergence and spread of bacterial resistance to antibiotics is a growing problem worldwide, which presents a significant threat to public health globally. The present study was designed to determine knowledge, attitude and practice of antibiotic use. A cross-sectional survey was performed using a questionnaire on a sample randomly selected from east Libya for pediatric doctors, pharmacies and parents. A total of 400 participating subjects were approached to be included in the study, 234 agreed to participate giving a response rate of 58.5%. The awareness of antimicrobial resistant was very high among the pharmacist and doctors responder (96.43%) (93.91%) respectively, in contrast participants parents (41.76%). More than one-third (37.36%) were self-medicated with antibiotics to treat mainly common cold and cough. The reasons of antibiotic misuse in the present study according to the opinion of participant doctors were an empirical use, incorrect dose and low level of education with 68.70%, 18. 26%, 13.04% respectively. Pharmacies are the major source of antibiotics reporting more than –quarter 28.57% were sold antibiotic without prescription. These findings presented aid in the assessment of the adequacy of present public educational campaigns to promote specific messages to rationalize antibiotic use, and compensate for knowledge and attitude gaps as an effort towards preventing development of antibiotic resistance.

Background: There is a sharp decline in new SARS-CoV-2 cases in Karachi from July onwards; most of them were asymptomatic. Seroconversion rates vary markedly in different countries. Previously, 36% of seropositivity was reported in the adult population of Karachi in July this year. The current study was conducted to report if seroprevalence has increased and has a possible role in community immunity. Methods: This was a prospective cross-sectional study conducted in the first and second weeks of September 2020 at the National Institute of Blood disease and Bone Marrow Transplantation Hospital (NIBD), Karachi, Pakistan. Blood samples were collected from different segments of the population of Karachi workforce/community. An anti-SARS-CoV-2 test was performed using ECLIA from Roche Diagnostics International. Results: A total of 2404 subjects’ blood samples were received from healthcare workers, the industrial workforce, and healthy blood donors. Seroprevalence in industrial workers was highest (70%) as compared to healthcare workers (40%). Overall seropositivity in males (39%) was higher than females (16%). Blood donors (all males) showed seropositivity of 37.8%. The comorbid state was not significantly associated with seropositivity (p-value >0.05). Total cases of antibody-positive were 1322 of 2100 (55%). Conclusion: Our results confirmed the current seroprevalence of 55% in the adult population in Karachi. There was a sharp rise from 36% reported previously in July. This rise coincided with a sharp decline in new reported COVID 19 cases. We can conclude that the adult population from Karachi has shown an upsurge in seropositivity which will certainly have a beneficial role in SARS-CoV-2 control in the future.

Etymologically, melatonin (N-acetyl-5-methoxytryptamine) can be traced back to the origin of life. The first origin of melatonin was detected in cyano-bacteria. As considering the endosymbiont hypothesis, cyanobacteria were engulfed by the animal and plant cells. Later on, these bacteria performed the roles of mitochondria and chloroplastids in animals and plant cells respectively. Inner matrices of these organelles are having melatonin and probable function of this intra-organelle melatonin is to protect the organelles from the detrimental effects from free radicals (Reactive Oxygen Species; ROSs and Reactive Nitrogen Species; RNSs). In higher animals, melatonin is synthesized and secreted by the pineal gland mainly during the night, since light exposure suppresses its production. Other than pineal gland, melatonin is secreted from several different organs like retina, gastro-intestinal tract. The secretion of this hormone is regulated by several environmental factors like photo-period, temperature, humidity etc. Melatonin can exert its function either by as a free molecule or by its membrane bound receptors MT1 and MT2 respectively. Modulations of melatonin receptors results in stimulation of apoptosis, regulation of pro-survival signaling, inhibition on angiogenesis, metastasis, and induction of epigenetic alteration. Melatonin could also be utilized as adjuvant of cancer therapies, through reinforcing the therapeutic effects and reducing the side effects of chemotherapies or radiation. Melatonin could be an excellent candidate for prevention and treatment of several cancers, such as breast cancer, prostate cancer, gastric cancer and colorectal cancer. This review summarized the anticancer efficacy of melatonin, based on the results of epidemiological, experimental and clinical studies.

Background: Metabolic syndrome describes the co-occurrence of central adiposity, hyperglycemia, hypertension, lipid abnormalities and other metabolic changes that increase risk of cardiovascular, cerebrovascular, renal diseases. Non-alcoholic fatty liver disease (NAFLD) is associated with a substantial increased risk of cardiovascular disease (CVD), which is partly related to low HDL-C level. This multi-system condition has adverse effects on many organs, the liver being one of them. Non-alcoholic fatty liver disease appears to be the hepatic manifestation of metabolic syndrome, and is increasingly recognized as a major contributor to the burden of chronic liver disease world-wide. Objective: To find out the Association of Low HDL of NAFLD Patients With or Without Metabolic Syndrome. Materials and Methods: This is a cross sectional descriptive study which was conducted in the Department of Medicine, Rajshahi Medical College Hospital, Rajshahi, Bangladesh. 250 patients age above 20 years nonalcoholic both male and female were included for the study. All patients were interviewed by structured questionnaire. Statistical analysis was carried out by using the Statistical Package for the Social Sciences (SPSS) software version 23.0 for windows (SPSS Inc, Chicago, Illinois, USA). Results: Among 250 respondents a total of 67(26.8%) cases were diagnosed as metabolic syndrome and out of the 67 metabolic syndrome patients 23(34.33%) were male and 44(65.67%) were female. Out of the 23 male metabolic syndrome patients 9(39.13%) were diagnosed as NAFLD and out of the 44 female metabolic syndrome patients 16(36.36%) were diagnosed as NAFLD. Out of the 53 NAFLD patient’s 25 patients were presented with metabolic syndrome and 28 patients were without metabolic syndrome. Patients of NAFLD with metabolic syndrome presented with low HDL in 16(64%) cases. The difference was significant for high-density lipoprotein and waist circumference (p<0.05) between metabolic syndrome and non-metabolic syndrome patients. Conclusion: From the study, it can be concluded that the proportion of NAFLD significantly higher in metabolic syndrome patients compare to non-metabolic syndrome patients and metabolic syndrome is higher in female compare to male. The results of this study indicate that central obesity and dyslipidemia, with low HDL cholesterol, are important associates of NAFLD in patients.

Bangladesh is used to struggle with several natural disasters and has become one of the most earthquake vulnerable countries of the world. The nature and the distribution of the earthquake events in different seismic zones of Bangladesh are related to various man-made factors. This study is dealing with the impact of these factors which are leading to the incidence of earthquakes. Geographic information system (GIS) is used to analyze earthquake data graphically. Bivariate analysis is conducted using t-test approach for hypothesis testing purpose. Availability of gas and oil has been turned out as significant in the results on earthquake occurrences. Three Poisson regression models, along with bivariate analysis, are employed in this study to assess the occurrence of earthquakes in relation with having minerals in Bangladesh. The results give evidence that the presence of minerals is vulnerable to earthquake and production of minerals increases the vulnerability. The presence of gas and oil in the related districts significantly increases the expected number of earthquakes. Keeping similarity with this result, the districts where gas and oil production are running also experience significantly more frequency of earthquakes compared to that of other districts. It is also found from the analysis that the more amount of gas the districts have, the higher the expected number of earthquakes is in that districts. However, neither presence of coal nor running of coal production has any significant effect on earthquake occurrence.

Introduction: Incidence of dengue infection has increased around the world in recent decades and has become a major international public health concern. Early diagnosis is essential and clinical suspicion is based on the frequency of symptoms in the population. The exact clinical profile is important for management and prognosis. Objective: This study is an attempt to describe the Clinical Characteristics & Observation of Hospitalized Cases of Dengue Fever: A Study in Tertiary Care Hospital, Dhaka, Bangladesh. Materials and Methods: A hospital-based prospective study was undertaken in the Paediatrics Dept. in Tertiary Care Hospital, Dhaka, Bangladesh (July -October 2018). NS1 antigen and IgM dengue antibody-positive cases were included. These patients were admitted with fever, myalgia, headache, vomiting, abdominal pain or bleeding manifestations. NS1 antigen and IgM dengue antibody was estimated using capture ELISA. The diagnosis of dengue fever, dengue hemorrhagic fever and dengue shock syndrome was based on the WHO (World Health Organization) criteria. Results: The study enrolled 101 patients of suspected dengue fever of whom 51 (50.49%) were serologically confirmed to have dengue infection. 28 (55.0%) patients were males and 23 (45.0%) were females. 38 (37.62%) patients had classic dengue fever while 12 (11.88%) fulfilled the criteria of dengue hemorrhagic fever. Of those patients with dengue hemorrhagic fever, 6 patients had developed dengue shock syndrome. Conclusion: Dengue presents as a highly unspecific illness and is hardly recognized as a clinical entity by primary health care physicians. Dengue infection can have potentially fatal consequences, and to date, vector control methods to prevent the spread of the virus have been unsuccessful. Although there are promising vaccine candidates in development, further studies are required for a greater understanding of the humoral immune responses to Dengue infection and observation disease pathogenesis.

This research aims to examine The Effect of Perceived Ease of Use on the Quality of Accounting Information Systems and its Impact on the Quality of Accounting Information using the Technology Acceptance Model (TAM) approach. Population in this research are the staffs at the accounting department, procurement/purchasing department, project support units, and productions in one of the oils &amp; gas companies in Jakarta. The samples are 60 respondents who operate the accounting systems and the Director and managerial level who use the accounting information. Data were collected using questionnaires that used the Likert scale. Distribution and collection of questionnaires were carried out in April 2020. The results of testing showed perceived ease of use affects the quality of information systems. However, the level of influence is also influenced by other factors outside the information system. Like standard operating procedures as internal company controls. Meanwhile, the accounting information quality is strongly influenced by the information system quality. The better the information system quality, the better the quality of the resulting accounting information system.
