Clinical Case of Bilateral Mandibular Auto Transplantation for Missing Bilateral First Molars: Case Report and Review of Literature
Abstract:
Auto transplantation is a fast and economical option when a suitable donor tooth is available for replacement of a tooth considered impossible to treat. The purpose of this case report is to describe methods used for autotransplantation and its advantages for cases with a missing bilateral mandibular firstmolar, as compared with a dental implant, removable partial denture, and other methods of prosthesis. In the present patient who underwent auto transplantation, clinical and radiographic outcomes were considered satisfactory at one and two years postoperatively. Bone healing was observed around the roots of transplanted teeth, which showed good function. In autotransplantation cases, even when the donor tooth has complete root formation, a high success rate can be achieved when the patient is properly selected and treated. Although the chance of root resorption remains because of necrotic pulp and periodon...
Factors Influencing Hospital Cleaners’ Knowledge and Practices toward Hepatitis B prevention in Northern Province of Rwanda
Abstract:
This study aimed to assess factors influencing knowledge and practices of hospital cleaners towards hepatitis B prevention. This was a hospital-based cross-sectional study conducted at in Northern Province of Rwanda. A pretested self-administered questionnaire was used to gather data from study participants. A total of 134 cleaners were recruited in the study. Data were entered using Kobo collect toolbox and exported to Microsoft office excel for data cleaning and to entered in SPSS version 21 for analysis. Descriptive and logistic regression analysis was done and the significance level was 5%. More than a half of respondents were female (51.5%), and had primary level of education (54.5%). Results showed that only 9.7% of respondents had a high level of knowledge about HBV and only 2.2% had good practices on HBV practices. The odds of having high level of knowledge towards HB...
Effect of Hours of Use and Age in Years in Estimating Repair and Maintenance Costs for Two Sizes of Agricultural Tractors in Northern Sudan
Abstract:
Repair and maintenance cost is considered as one of important items for machinery management and selection. The present study was carried out in Dongola area for tractor repair and maintenance costs estimation. The data was collected from records of Elshimalya Company for Agricultural Inputs. Forty four tractors rep resenting two sizes of tractors, 75hp and 150hp used in the area were selected for this study. Based on the data collected, regression correlation analysis was carried out and mathematical models were derived to predict the accumulated repair and maintenance (R and M) costs as percent of purchase price in relation to accumulated hours of use and age (years) for each tractor size, and also for the two sizes collectively. Five model forms (linear, logarithmic, polynomial, power and exponential) were derived and the power function was found the best fit to explain the relation. The accumulat...
Attenuation of Microcystins Using Electron Beams and Gamma Radiation: A Study with Environment-Bound Conditions
Abstract:
Microcystins (MCs) are toxins profusely synthesized by cyanobacteria, causing livestock poisonings and endangering human health. We design and execute an experiment to investigate the attenuation (degradation) of microcystins by exposing them to gamma radiation and electron beams at doses of 0 (control), 3, 5, 10 and 15 kGy. The experimental conditions simulate microcystin contamination of aquatic environments; we thus consider (1) microcystins inside whole cells and extracellular dissolved in water, simulated by non-sonicated and sonicated cells, respectively, and (2) two acute microcystin concentrations within water. Toxicity tests of
Aging and Positive Psychology
Abstract:
Aging, a state often associated with poor emotional health status greatly impedes life quality and independence for many. This mini review examines the potential of the concept of positive psychology as an active approach to fostering successful or more successful, rather than suboptimal aging. Articles that addressed the current topic of interest and were located in the PUBMED, Medline, Web of Science, PsycINFO and Google Scholar electronic data bases were carefully sought and analyzed and presented in narrative form. Various f...
Colorectal Cancer in Africa: Causes, Dietary Intervention, and Lifestyle Change
Abstract:
Colorectal cancer (CRC) is a menace in the global public health system. According to GLOBOCAN reports, colorectal cancer is the second most diagnosed cancer in the world with more than 1.9 million cases and 935,000 deaths in 2020 alone. Diet plays a key role in exposing humans to environmental carcinogens and anti-carcinogens, consequently mitigating or aiding in the development of various cancers. CRC is most prevalent in western countries with a high intake of saturated fats, refined carbohydrates, and processed meat. CRC was an extremely rare disease in Africa some decades ago, but the situation is fast changing. The traditional African diet consists of leafy, roots and cruciferous vegetables, fruits, roots, tubers and plantains, legumes, whole grains, and spices, all of which have been shown to possess protective effects against CRC. However, the effect of urbanization has contrib...
From High-Risk Behaviors to Problem-Solving Strategies: Acceptance and Commitment Therapy Effects on Addiction Susceptible Adolescents in Cyberspace
Abstract:
This study aimed to evaluate acceptance and commitment therapy (ACT) effectiveness in reducing high-risk behaviors and elevating problem-solving strategies in adolescents with addiction susceptibility in cyberspace. This study is longitudinal with quantitative methods of data collection and analysis. The target community in this research was 60 female students randomly selected from a Persian high school in Iran. Participants were randomly divided and placed equally into the experimental and control groups. The participants’ entry criteria were gender, aged from 15 to 18 years, addiction susceptibility, and high-risk behaviors cut-off points. Eight training sessions of ACT were presented in cyberspace for the experimental group between the pre-test and post-test intervals. Data collection instruments were the Iranian youth risk-taking scale, problem-solving strategies, and Iranian adolescents’ addiction susceptibility q...
The Use of Metabolomic Tool in Assessing Environmental Exposure
Abstract:
The impact of the environment on the development of non-communicable chronic diseases has gained prominence in recent years. In this context, a new chemical exposure assessment strategy is needed that is capable of revealing multiple exposures, as well as reflecting the cumulative interaction between such environmental contaminants in the biological system. From this perspective, metabolomics emerges as a promising tool in this field of knowledge, since it is able to identify changes in metabolism and/or gene expression resulting from exposure to environmental factors. The aim of this study was to describe important concepts, as well as the steps that permeate the metabolomics analysis, and also to present some relevant works with the application of metabolomics in the assessment of chemical exposure. A literature review showed a significant increase in the use of metabolomics in environmental toxicology in recent years. This increase is mainly due to advances in ...
Antioxidant Activity of Pod Coat Extracts of Pigeon Pea (Cajanus Cajan L.) and Their Efficacy in Stabilization of Soybean Oil
Abstract:
When lipids are exposed to heat, light and oxygen, it leads to oxidation. The addition of antioxidants is required to preserve colour, flavour and vitamin destruction. Present study was, therefore, planned to investigate pod coat of pigeon pea as possible sources of natural antioxidants and to assess their efficacy in stabilization of crude soybean oil during normal storage (28 days at 50°C). Study revealed that acetone pod coat extract of pigeon pea showed richness in total phenolics (17.72 mg/g), flavonoids (9.00 mg/g) and tannins (2.21 mg/g) while the extract of ethyl acetate was found enriched in tocopherols content (9.56 mg/g). The IC50 value of acetone extract was found to be lowest, exhibited potent antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric thiocyanate (FTC) methods. After adding synthetic and natural antioxidants in oil, Peroxide, p-Anisidine, Th...
