Abstract:Abstract. This article concerns a modified Lienard equation with multiple variable time lags. We investigate the Hyers-Ulam stability (HUS) and Hyers-Ulam -Rassias (HURS) stability (HURS) of the equation considered. Our approach is based on the use of Banach’s contraction principle. The obtained results are new and original, and they have a contrubition to the works found in literature.
Abstract:Blastocystis is a unicellular, globally distributed intestinal parasite infecting humans and a wide range of animals. Several studies have demonstrated that Blastocystis isolates from animals were genotypic homology to humans isolates which leads to an assumption that Blastocystis in humans might be of zoonotic origin. This led us to investigate the existence of Blastocystis in Javan rusa (Cervus timorensis) and sika deer (Cervus nippon). The samples of Javan rusa (25) and sika deer (25) were collected from Sungai Jin Deer Farm, Pahang, Malaysia. Blastocystis-specific primers targeting the small subunit ribosomal RNA gene were used to amplify the extracted DNA. Positive Blastocystis were detected in Javan rusa by 28% (7/25), whilst 32% of it were detected (8/25) in sika deer. It was revealed through phylogenetic analysis that these species belong to ST10. To the best of our knowledge, this is the first study in Malaysia that successfully isolates Blastocystis in these animals. Besides, the findings highlighted that Blastocystis is carried by deer, and it can be a potential reservoir for parasites. However, this eliminates the risk of zoonotic transmission amongst this species, as ST10 has never been found infecting humans. Nevertheless, awareness and associated precautions must be taken by the animal handlers to minimize the environmental contamination that may occur from deer to their surroundings.

Abstract:The otter (Lontra longicaudis) inhabits rivers, dams, lakes and coastal lagoons from northern Mexico to Uruguay. Otters are tolerant to environmental changes; however, they are endangered species and are listed as threatened in the NOM- 059- SEMARNAT- 2010. Their diet is composed primarily by fish and crustaceans, which are intermediate hosts of various endoparasites. The aim of this study was to carry out fecal analyses studies in neotropical otter populations inhabiting the Alvarado Lagoon System (ALS). Transects were carried out in the ALS, mainly in mangroves, lagoons, and rivers; hence most otter observations were made in those places. Fresh feces were collected and identified by their content, odor and location, and then labeled and stored. Parasites were identified using the fecal analyses of direct smear and the flotation technique. A total of 52 feces samples from 16 sampling sites in nine regions of the ALS were analyzed. Out of the total of feces, 42% were positive for endoparasites. Seven parasites genera were identified and one oocyst could not be identified. The parasites were classified according to their Phylum and frequency: Nematodes: Anisakis sp. 24%, Trichuris sp. 8%, Enterobius sp. 4%, Toxocara sp. 20%, Strongyloides sp. 24%; Trematodes: Opisthorchis sp. 4%, Paragonimus sp. 4%; Apicomplexa: Oocyst Unknown 12%. The site with the highest number of parasitized otters was the Acula River. ALS otters are housing a great variety of endoparasites. These parasites are a threat to the conservation of these species and to public health.
Abstract:In this paper we present an Adaptive and Smart Assessment Model named (ASAM). The approach employed in ASAM emphasizes the fact that students perceive and process information in very different ways. The preferred ways of students to gain and retrieve information are termed the students learning style. Learning styles has become important factor in the learning process. When learning style considered in teaching and learning process, every student will receive learning materials that fit his/her abilities. This will be improving learning and making it easier for students to understand. Our aim in this paper to develop assessment model that customizes assessment tasks for each student and provides students with assessment tasks that match his/her learning style to ensure that student understand carefully. This will improve assessment result and make assessment more accurately to measure student knowledge level. ASAM determines the students\' abilities, skills and preferable learning style with more accuracy and then generates the appropriate questions in an adaptive way, then presents them in a preferable style of student.
Abstract:In the present study, hypoglycemic and anti-obesity effects of a mixed Momordica charantia water extract (MC): platycodin (PL) (1:4) formula (MMP) were observed in obese db/db mice at doses of 10, 50, 100 and 200 mg/kg; these effects were also seen with MC alone and PL alone at 200 mg/kg. The effects were compared to those of metformin, which improves insulin resistance and inhibits obesity at 250 mg/kg. The test agents were administered orally, to db/m and db/db mice, once a day for 28 days. Mice were classified into nine groups (7 mice per group) according to body weight and fasting blood glucose level one day before dosing began. After 28 days, changes in body weight, blood glucose, epididymal fat, serum leptin, adiponectin, adipose adiponectin, and liver triglycerides were recorded. Prior to test agent administration, db/db mice showed marked obesity compared to db/m mice (normal littermates) with severe hyperglycemia. Epididymal fat, serum leptin and liver triglycerides in obese controls were significantly increased compared to those of intact controls (p<0.01), whereas serum adiponectin and adipose adiponectin were significantly decreased in the obese group (p<0.01). However, these obesity- and hyperglycemia-related changes were dramatically and dose-dependently inhibited by MMP treatment, and more favorable outcomes were seen in the MMP groups compared to the MC alone and PL alone groups. Furthermore, MMP at 50 mg/kg was associated with similarly beneficial outcomes regarding diabetes and diabetes-related obesity compared to 200 mg/kg MC alone or PL alone, and MMP at 100 mg/kg showed similar efficacy to 250 mg/kg metformin. Based on the present results, MMP has synergic and beneficial effects on diabetes and diabetes-related obesity. Therefore, MMP shows promise as a novel complementary approach for managing diabetes and diabetic obesity at a reasonable dosage.
Abstract:Objective: To summarize the scientific production nationally and internationally about the triggers of stress and burnout syndrome in nurses in Intensive Care Units, as well as the consequences of these types of wear to the health of nurses and the provision of care. Methodology: It is an integrative review, which answers the guiding question: What are the main factors related to stress and burnout syndrome in nurses in Intensive Care Units? We sought to in SciELO, LILACS and MEDLINE/PUBMED, published between 2008 and 2015, using the descriptors: burnout, nursing and intensive care unit in portuguese, english and spanish. We selected 12 articles, which were subjected to careful reading and critical analysis by pairs, then grouped and organized in tables, summarized and discussed. Results and Discussion: The triggers of stress are the confrontation with suffering, heavy workload and the lack of autonomy, presenting symptoms such as cardiovascular disorders, musculoskeletal and humor. Already the Burnout Syndrome is characterized by the professional exhaustion, depersonalization and low professional achievement. Conclusion: These factors must be evaluated in organizations, in order to establish rational implementations for the satisfaction, quality of care and the minimization of Stress and Burnout Syndrome.
Abstract:Objective: report the experience lived in the Specialized Service for people living with HIV/AIDS (PLWHA) in order to identify the difficulties surrounding the establishment and maintenance of partnerships for these people. Method: A descriptive study was carried out in a Specialized Attention Service (SAE) of a Brazilian Integrated Health Center from December 2016 to May 2017. The study population consisted of PLHA, adults of both sexes, who has been in a relationship (fixed or casual) in the last 30 days. Results: The activities developed in the service involved the initial approach and approach with the PLHA, and later identification of the interfaces to live with HIV and to be welcomed by an SAE. Next, we determined the living in the context of HIV and the main needs of Health literacy. Conclusion: There is a gap between the care of patients with HIV in a holistic manner and the establishment of safe sex partnerships, strategies implemented by specialized customer service to people with this infection are still incipient.
Abstract:The microalgae culture collections are centers which have fundamental functions in preserving and providing algae sources. Those collections contribute to the matters of identification, isolation, culturing and ex situ preservation of microalgae as well as serving as a biological source. Taking those important functions of culture collections into consideration, the efforts to create The Culture Collection of Algae at University of Ahi Evran (AEU-CCA) have started. Our culture collection consists of totally 19 microalgae species belonging to the phylums of Cyanobacteria, Chlorophyta, Charophyta and Bacillariophyta. Collecting microalgae from fresh water bodies, their identification, isolation and arrangement of culture conditions have begun to be carried out and it is a still-continuing process. While the microalgae are preserved in broth medium by sub-culturing, their long-term preservation studies through cryopreservation have begun. The present study mainly aims to put isolated microalgae species at the disposal of scientific communities, to conduct biotechnological studies and to arrange the microalgae culture collection in order to maintain biological diversity.
Abstract:This study aimed to analyze the meaning of violence against the elderly and to identify the possible factors associated with the occurrence of violence against the elderly from the perspective of nursing students. This is a descriptive and exploratory study with qualitative approach where information was collected from 29 nursing students through interviews using questions based on Ogden Richards\' Representational Theory. It was possible to analyze the use of symbols to analyze the meaning of violence against the elderly, especially those related to taking money, beating and disrespecting. Aspects related to the causes and consequences of this violence, denunciation to the police, to social services and conversation with the family of the elderly were also recognized. These aspects made up the meaning of thought in relation to the role of nurses in cases of violence against the elderly. The findings of this study show the importance of continuing education, so that this may not be carried out only during undergraduate and postgraduate training, but throughout permanent education, so that nurses be able to act in the prevention and care against violence practiced against the elderly in a more effective manner.
