Active Methodologies in Teaching Human Anatomy: An Integrative Review

Human anatomy is one of the fundamental disciplines for the training of health professionals, especially in the medical field. Its didactic origin is based on the European school where the body was dissected in amphitheaters and anatomical knowledge was transmitted from the teacher to his students. With the restructuring of medical curricula, and the use of active methodologies, seeking to make the student the center of the learning process, anatomy started to be taught in another way. This study carries out an integrative review in the Scielo, Science Direct and Google Scholar databases, from 2015 to 2020, about the active methodologies used in the teaching of human anatomy for the medical course. The PICo strategy was used to form the guiding question and the results were presented through the Prisma Flow diagram. It was found that there are a number of tools and strategies that can be used aiming at the active teaching of human anatomy, however, a common point observed in most works is the approach of joint use with cadavers and anatomical parts, thus seeking to stimulate the development of the skills and competences of medical students

Carbohydrates plus protein reduces oxidative stress after single bout of aerobic exercise

The aim of this study was to investigate the effect of CPA in muscle damage and oxidative stress induced by aerobic exercise. Participate in the study ten healthy young (24 ± 4 years), eutrophic (23.2 ± 1 kg/m2),VO2max = 44.9 ± 10 ml/kg/min, four women performed three aerobic exercise sessions lasting 50 minutes randomly supplemented with water (WAT), isolated carbohydrate (CHO) or carbohydrate associated with proteins and antioxidants (CPA) every 10 minutes of exercise. Blood samples were taken before, immediately and 24 hours after each exercise session for analysis markers of muscle damage creatine kinase (CK) and oxidative stress malondialdehyde (MDA). Blood glucose was measured before, during and after the exercise. After testing the data for normality and homogeneity through the Shapiro-Wilk and Levine tests, one-way ANOVA or two-way analyses were made to compare the initial and the answers to the experimental procedure respectively, or their corresponding non-parametric. CHO and CPA resulted in maintaining or increasing glucose, respectively, during exercise, whereas WAT resulted in glycemia reduction. CHO or CPA did not affect CK post exercise concentration. MDA values were very similar immediately after exercise between CHO and CPA, however occurred significant reduction from post exercice to 24 hours after exercise in CPA procedure (4.8 ± 1.8 to 2.5 ± 0.8, p <0,05), while CHO (5.1 ± 0.8 to 4.6 ± 0.9) and WAT (4.9 ± 0.9 to 5.1 ± 0.6) did not promotes the same phenomenon. This study revealed that carbohydrates associated with proteins and antioxidants have ergogenic effect by increasing blood glucose during a single bout of aerobic exercise and accelerate the restoration of oxidative stress

3D printing as a tool in anatomy teaching: An integrative review

Anatomy is essentially a three-dimensional content and learning its structures, through 3D impressions, for example, is of notable importance. In this context, traditional teaching methods, despite being highly effective, still have some limitations. Therefore, 3D printing has been introduced in the teaching of Anatomy, bringing several advantages, such as accuracy, personalized study and easy handling. Based on these premises, the objective of this work was to carry out an integrative review on the use of 3D printing in the teaching of human anatomy. A study was carried out in science direct, PUBMED, Scielo databases between 2010 and 2021 using the following descriptors 3D printing and teaching of anatomy. It was found that among the benefits of using 3D parts, there are: accuracy, durability, ease of production, good cost-benefit ratio and reduction of security risks linked to the fixation of cadaver and plastinated specimens. It was observed that in some studies most students preferred the use of 3D printing to traditional methods. Other studies have shown the importance of the use of 3D printing as a complementary tool to traditional methods of teaching anatomy. It was found that the use of 3D printing as a teaching tool may reduce the demand for bodies and overcome some of the governmental legal and ethical problems in the cadaver study, further studies should be carried out to assess the long-term impact of using 3D printing

Effects of hecogenin and its possible mechanism of action on experimental models of gastric ulcer in mice

This study investigates the gastroprotective effects of hecogenin, a steroid saponin isolated from Agave sisalana, on experimental models of gastric ulcer. Male Swiss mice were used in the models of ethanol-and indometacin-induced gastric ulcer. To clarify the hecogenin mechanism of action, the roles of nitric oxide (NO), sulfhydryls (GSH), K-ATP(+) channels and prostaglandins were also investigated, and measurements of lipid peroxidation (TBARS assay) and nitrite levels in the stomach of hecogenin-treated and untreated animals were performed. Furthermore, the effects of hecogenin on myeloperoxidase (MPO) release from human neutrophils were assessed in vitro. Our results showed that hecogenin (3.1, 7.5, 15, 30, 60 and 90 mg/kg, p.o.) acutely administered, before ethanol or indomethacin, exhibited a potent gastroprotective effect. Although the pretreatments with L-NAME, an iNOS inhibitor, and capsazepine, a TRPV1 receptor agonist, were not able to reverse the hecogenin effect, this was reversed by glibenclamide, a K-ATP(+) blocker, and indomethacin in the model of ethanol-induced gastric lesions. the hecogenin pretreatment normalized GSH levels and significantly reduced lipid peroxidation and nitrite levels in the stomach, as evaluated by the ethanol-induced gastric lesion model. the drug alone increased COX-2 expression and this effect was further enhanced in the presence of ethanol. It also decreased MPO release and significantly protected the gastric mucosa. in conclusion, we showed that hecogenin presents a significant gastroprotective effect that seems to be mediated by K-ATP(+) channels opening and the COX-2/PG pathway. in addition, its antioxidant and anti-inflammatory properties may play a role in the gastroprotective drug effect.

Omega-3 fatty acids: possible neuroprotective mechanisms in the model of global ischemia in rats

Background. Omega-3 (omega 3) administration was shown to protect against hypoxic-ischemic injury. The objectives were to study the neuroprotective effects of omega 3, in a model of global ischemia. Methods. Male Wistar rats were subjected to carotid occlusion (30 min), followed by reperfusion. The groups were SO, untreated ischemic and ischemic treated rats with omega 3 (5 and 10 mg/kg, 7 days). The SO and untreated ischemic animals were orally treated with 1% cremophor and, 1 h after the last administration, they were behaviorally tested and euthanized for neurochemical (DA, DOPAC, and NE determinations), histological (Fluoro jade staining), and immunohistochemical (TNF-alpha, COX-2 and iNOS) evaluations. The data were analyzed by ANOVA and Newman-Keuls as the post hoc test. Results. Ischemia increased the locomotor activity and rearing behavior that were partly reversed by omega 3. Ischemia decreased striatal DA and DOPAC contents and increased NE contents, effects reversed by omega 3. This drug protected hippocampal neuron degeneration, as observed by Fluoro-Jade staining, and the increased immunostainings for TNF-alpha, COX-2, and iNOS were partly or totally blocked by omega 3. Conclusion. This study showed a neuroprotective effect of omega 3, in great part due to its anti-inflammatory properties, stimulating translational studies focusing on its use in clinic for stroke managing.Faculty of Medicine, Estácio of Juazeiro do Norte (FMJ), Rua Tenente Raimundo Rocha 515, 63040-360 Juazeiro do Norte, CE, BrazilFederal University of Ceará (UFC), Rua Coronel Nunes de Melo 1127, 60430-270 Fortaleza, CE, BrazilFederal University of São Paulo (UNIFESP), Rua Pedro de Toledo 669, 04039-032 São Paulo, SP, BrazilFederal University of São Paulo (UNIFESP), Rua Pedro de Toledo 669, 04039-032 São Paulo, SP, BrazilWeb of Scienc

Clinical And Surgical Anatomy Of Lumbar Hernia: A Review

Lumbar hernia is defined as the presence of failure in the transverse fascia or in the aponeurosis of the transverse abdominal muscle that results in the extrusion of intra or extra peritoneal organs through the discontinuity of the postero lateral abdominal wall. The aim of this study was to conduct a methodical review of the anatomy of the hernia form grynfelt dated from 2006 to 2017. For this, we performed a bibliographic review by means of electronic databases like SciELO, PubMed, Science Direct, LILACS and Bireme to get better approach to the subject. It has been found that the lumbar hernia is a disease little known by doctors whose diagnostics are often performed in the wrong way and for surgical correction needs a good anatomical knowledge. Lumbar hernias, although rare, must be taken into account, since ischemia of herniated intestinal segments can lead to the death of the patient, especially in the elderly. Knowledge about the anatomy of the lumbar region is of vital importance because it makes surgery safe and reduces risks of complications and recidivating of the hernia

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
