CONCEPTUALIZAÇÃO E COERÊNCIA CURRICULAR EM EDUCAÇÃO CIENTÍFICA: UMA PROPOSTA DE INTERVENÇÃO PEDAGÓGICA
Authors: Morais Ana Maria , Neves Isabel Pestana , Ferreira Sílvia , Afonso Margarida , Silva Preciosa
Published: May 2020

O artigo apresenta uma proposta de intervenção pedagógica sustentada em fundamentos teóricos e empíricos que permitem defender uma educação científica conceptualmente exigente, para todos os alunos e aos vários níveis de escolaridade. Argumenta-se que o nível de conceptualização e de coerência curricular de conhecimentos e de capacidades cognitivas deve ser central em currículos e práticas pedagógicas. Argumenta-se também que a relação intradisciplinar, conjuntamente com a exploração de conhecimentos e de capacidades de nível complexo, eleva o nível de exigência conceptual da aprendizagem científica e promove um ensino que considera a estrutura hierárquica característica do conhecimento científico. A proposta de intervenção pedagógica, centrada na inter-relação fotossíntese-respiração, exemplifica a articulação conceptual que deve existir, em contextos de aprendizagem da ciência, entre os vários níveis de escolaridade. Discute-se a importância da implementação de atividades que propiciem aprendizagens científicas conceptualmente e coerentemente articuladas, o que pode exigir uma recontextualização dos currículos, sempre que tal não seja valorizado nos documentos curriculares oficiais.

OBJECTIVE

In patients with type 2 diabetes (T2D) and critical limb ischemia (CLI), migration of circulating CD34+ cells predicted cardiovascular mortality at 18 months after revascularization. This study aimed to provide long-term validation and mechanistic understanding of the biomarker.

RESEARCH DESIGN AND METHODS

The association between CD34+ cell migration and cardiovascular mortality was reassessed at 6 years after revascularization. In a new series of T2D-CLI and control subjects, immuno-sorted bone marrow CD34+ cells were profiled for miRNA expression and assessed for apoptosis and angiogenesis activity. The differentially regulated miRNA-21 and its proapoptotic target, PDCD4, were titrated to verify their contribution in transferring damaging signals from CD34+ cells to endothelial cells.

RESULTS

Multivariable regression analysis confirmed that CD34+ cell migration forecasts long-term cardiovascular mortality. CD34+ cells from T2D-CLI patients were more apoptotic and less proangiogenic than those from control subjects and featured miRNA-21 downregulation, modulation of several long noncoding RNAs acting as miRNA-21 sponges, and upregulation of the miRNA-21 proapoptotic target PDCD4. Silencing miR-21 in control CD34+ cells phenocopied the T2D-CLI cell behavior. In coculture, T2D-CLI CD34+ cells imprinted naive endothelial cells, increasing apoptosis, reducing network formation, and modulating the TUG1 sponge/miRNA-21/PDCD4 axis. Silencing PDCD4 or scavenging reactive oxygen species protected endothelial cells from the negative influence of T2D-CLI CD34+ cells.

CONCLUSIONS

Migration of CD34+ cells predicts long-term cardiovascular mortality in T2D-CLI patients. An altered paracrine signaling conveys antiangiogenic and proapoptotic features from CD34+ cells to the endothelium. This damaging interaction may increase the risk for life-threatening complications.

Introduction: Malaysia is situated in the southeast region of the Asian continent. Oral health services became prominent in the 1970s as programs related to oral health care were gradually introduced in schools. Various national epidemiological surveys were done to assess the prevalence of dental caries among children in Malaysia. This study was aimed to find out the DMF-t index level among school children based on their parents’ socioeconomic status by collecting consideration of education level and income of the fathers. Methods: This descriptive research with the survey technique was conducted at SJK (T) Klebang, Chemor, Perak, Malaysia. The DMF-t index of children in SJK (T) Klebang, Chemor, Perak was 0.2. Based on the questionnaire, the majority of fathers in Chemor, Perak were in the upper secondary education level with income ranging from RM 500 – RM 1000. Results: The Malaysian Oral Health Survey on 5-years old children showed that the caries prevalence was 75.5%. The mean of DMF-t was 5.57. An oral epidemiological study showed that 95.4% of 6-years old children in Peninsular Malaysia had carious primary teeth. This figure dropped to 88.6% in 1988, and by 1997 a further reduction to 80.6% was reported. DMF-t index consisted of the total number of Decayed, Missing and Filled teeth as well as a questionnaire on the socioeconomic background of the parents. Conclusion: The DMF-t Index of children in SJK (T) Klebang based on their father’s socioeconomic status is within the range of “Very Low” based on the DMF-t Index Scale.

Introduction: Composite polymerization is a polymer molecule formation from monomeric molecules. To obtain good physical and mechanical properties of composite resin restoration, the dental composite resin must have the possibility of an optimal quantity of its monomer converted to the polymer during the polymerization reaction. The type, size, and content of the fillers in the composite are also essential factors in the polymerization process. A hardness test can be used to indirectly measure the hardness ratio of the upper and lower surfaces of the composite material (relative curing degree). The objective of this study was to analyze the differences in the hardness ratio of the upper and lower surface between LED-activated hybrid composite resin and nano composite resin. Methods: Thirty composite resin samples were randomly selected and divided into 2 groups. Group I was the hybrid composite resin group and Group II was the nano composite resin group. Samples were then formed into discs with a diameter of 6mm and a thickness of 2mm and polymerized using LCU LED with a light intensity of 800 mW/cm2 for 20 seconds. After 24 hours, the upper and lower surfaces of each sample were tested for three testing points using Vickers Hardness Tester. The data were then analyzed using the t-test. Results: The hardness ratio between the upper and lower surfaces (relative curing degree) of the hybrid composite resin and nano composite resin was 0.93 and 0.88 consecutively. Conclusion: There is any difference between the upper and lower surface hardness ratio of LED-activated hybrid composite resin and nano composite resin.

Introduction: Enamel print pattern is a series of lines representing the enamel rod ends pattern. These lines are seen running in varying directions creating distinct sub-patterns; thus, enamel print pattern allows for personal identification. This study was aimed to investigate the enamel print pattern in Deutero-Malay sub race based on extracted female permanent maxillary central incisors. Methods: This study used descriptive-analytic methods. The population of this study was Deutero-Malay sub-race female individuals who came to Batu Pahat Dental Surgery, Johor, Malaysia. The samples were 31 post-extracted permanent maxillary central incisors teeth in good condition, with closed root apex. Photomicrographs and a digital photo of samples were taken, then analysed using SourceAFIS-1.7.0 biometric software. Results: The results showed that there was a combination of few sub-patterns. The most prominent sub-pattern was linear-branched (21.36%), in decreasing orders of prominence were the wavy-branched (19.42%), wavy-unbranched (16.50%) and linear-unbranched (15.53%). The less common sub-patterns were the whorl-open (9.71%), loop (6.80%), whorl-closed (5.83%) and stem-like (4.85%). Conclusion: The enamel print pattern in every central incisor has no similarity; hence can be a possible tool for personal identification.
