A produção de texto no ensino fundamental: uma experiência pedagógica

From a diagnostic on the learning of written text, this research aimed to carry out educational activities aimed at textual production, performing operation and activity of reflection on texts written by students in a learning situation of parallel recovery, aiming to improve the standard textuality of his written production. These actions were guided from the conception of language as social practice and discourse and, later, a survey was made in the standard of textuality textual productions resulting from such actions. 5 students participated in the research of a 4th grade of elementary school, a School of Duartina peripheral zone integrating the local school system of that city. The textual productions written by these students were analyzed from three categories: common mistakes in the process of literacy, with subdivisions: phonetic transcription, dialetação, hollow hipossegmentação or vocabulary, or improper separation hiperssegmentação, overcorrection, exchange, omission or addition letters, phonemes homorganic exchange; factors textual and contextual, in which it reviewed the following factors: coherence, cohesion and story elements, clarity, in which category were analyzed: the segmentation of text into paragraphs, grammar errors of different nature, use of direct and indirect speech. The results of the intervention and ongoing analysis of data shows that there has been considered developments in the performance of the written production of the research subjects

Redox-tagged peptide for capacitive diagnostic assays

Early detection assays play a key role in the successful treatment of most diseases. Redox capacitive biosensors were recently introduced as a potential electroanalytical assay platform for point-of-care applications but alternative surfaces (besides a mixed layer containing ferrocene and antibody receptive component) for recruiting important clinical biomarkers are still needed. Aiming to develop alternative receptive surfaces for this novel electrochemical biosensing platform, we synthesized a ferrocene redoxtagged peptide capable of self-assembly into metallic interfaces, a potentially useful biological surface functionalization for bedside diagnostic assays. As a proof of concept we used C-reactive protein (CRP), as a model biomarker, and compared the obtained results to those of previously reported capacitive assays. The redox-tagged peptide approach shows a limit of detection of 0.8 nmol L 1 (same as 94 ng mL 1 ) and a linear range (R2 ∼98%) with the logarithm of the concentration of the analyte comprising 0.5–10.0 nmol L 1 , within a clinical relevant range for CRP.

Evaluation of measurement errors of temperature and relative humidity from HOBO data logger under different conditions of exposure to solar radiation

This study aimed to assess measurements of temperature and relative humidity obtained with HOBO a data logger, under various conditions of exposure to solar radiation, comparing them with those obtained through the use of a temperature/relative humidity probe and a copper-constantan thermocouple psychrometer, which are considered the standards for obtaining such measurements. Data were collected over a 6-day period (from 25 March to 1 April, 2010), during which the equipment was monitored continuously and simultaneously. We employed the following combinations of equipment and conditions: a HOBO data logger in full sunlight; a HOBO data logger shielded within a white plastic cup with windows for air circulation; a HOBO data logger shielded within a gill-type shelter (multi-plate prototype plastic); a copper-constantan thermocouple psychrometer exposed to natural ventilation and protected from sunlight; and a temperature/relative humidity probe under a commercial, multi-plate radiation shield. Comparisons between the measurements obtained with the various devices were made on the basis of statistical indicators: linear regression, with coefficient of determination; index of agreement; maximum absolute error; and mean absolute error. The prototype multi-plate shelter (gill-type) used in order to protect the HOBO data logger was found to provide the best protection against the effects of solar radiation on measurements of temperature and relative humidity. The precision and accuracy of a device that measures temperature and relative humidity depend on an efficient shelter that minimizes the interference caused by solar radiation, thereby avoiding erroneous analysis of the data obtained.

S-100 protein: is it useful as a tumour marker in diagnostic immunocytochemistry

A heterogeneous group of 159 tumours was studied for the presence of S-100 protein by the immunoperoxidase technique in order to determine whether this marker may be of value in facilitating immunocytochemical diagnosis. Among cases of melanocytic and pigmented lesions, S-100 was widely distributed and demonstrated the strongest degrees of reactivity. S-100 protein was identified in virtually all nerve sheath tumours such as schwannomas, neurofibromas, myxoid sheath nerve tumour and also in some tumours of controversial histogenesis such as granular cell tumours. The great majority of carcinomas did not express S-100, with only two cases of breast carcinoma displaying focal S-100 staining. In a miscellaneous group of tumours S-100 was demonstrated in chordomas, myoepitheliomas and Wilms' tumour with Schwann cell differentiation. Despite its presence in a wide array of cell types, S-100 protein continues to be an extremely useful marker especially for soft tissue and peripheral nervous system tumours.
