Considering the articulation between continued formation and the educative work in the Education of Children, based on the axis of interactions and plays, in this text we present a bibliographic study which analyzed academic productions about the topics of continued formation and the act of playing, present in the first level of basic education. Based on bakhtinian theoretical methodological approaches, we aimed to understanding in which manner the researches that associate continued formation, the act of playing, and the Education of Children are conducted, selecting works from CAPES Theses and Dissertations database, from the 07 and 08 ANPEd groups of study, and from SciELO database. The analysis of the data corpus point to the necessity of investments on continued formation actions related to the act of playing and its interface with the educative work with children, in order to achieve pedagogical practices based on playing.

Staphylococcus aureus produces exoproteins that contribute to its ability to colonize the mammary gland such as hemolysins, coagulase, slime, and protein A. This study characterized phenotypically and genotypically these virulence factors in 50 Staph. aureus isolates. These isolates were obtained from milk samples from subclinical mastitis cases identified in 15 dairy cattle farms located in the state of Rio de Janeiro, Brazil. All of the confirmed Staph. aureus samples were PCR positive for the coa gene, which displayed 3 different size polymorphisms. The amplification of the spaA X region yielded a single amplicon for each isolate with the prevalent amplicon sized 315 bp. The Staph. aureus isolates were 24 and 16% positive for the hla and hlb genes, respectively, and 22 and 20% positive for the icaA and icaD genes, respectively. Amplification of the agr gene RNAIII was positive in 74% of the strains. Twenty-seven different profiles were identified among the samples, indicating a great diversity of Staph. aureus involved in the etiology of mastitis cases in the analyzed region. These findings are valuable to the comprehension of the distribution of the profiles of Staph. aureus strains isolated from subclinical mastitis cases in the state of Rio de Janeiro.

The use of medicinal plants dates back to the beginning of humanity, and today their application as complementary therapy has been widely disseminated as an alternative to conventional therapy. The medicinal plant named Uncaria tomentosa (Willd.) DC. (known as cat's claw) is a common woody vine of the Amazon forest that has traditionally been used in the treatment of arthritis because of its anti-inflammatory properties. This study aimed to evaluate the cytotoxic, mutagenic, and antimutagenic potentials of this medicinal plant. The biological activities of U. tomentosa were determined on bone marrow cells of Wistar rats that were treated in vivo. For the cytotoxic and mutagenic analyses, aqueous plant extract solutions were administered by gavage (1, 2, or 3 mg/mL) for 24 h (an acute treatment) or 7 days (a subchronic treatment). For the antimutagenic analyses, aqueous plant extract solutions (1 mg/mL) were administered by gavage before (pretreatment), simultaneous to (simultaneous treatment), or after (post-treatment), the administration of cyclophosphamide (1.5 mg/mL). U. tomentosa did not show any cytotoxic or mutagenic effects in any of the cytological or chromosomal analyses. Besides, the antimutagenic tests showed that the plant extracts displayed antimutagenic activities, which significantly reduced the percentages of the chromosomal aberrations that were induced by cyclophosphamide at 53.91, 58.60, and 57.03%, respectively, for the simultaneous treatment, pretreatment, and post-treatment. The results suggested a safe use of this herbal medicine that is available free of charge from the Brazilian Public Health System for the treatment of arthritis. This medicinal plant can also effectively contribute to improving the quality of life and the recovery of people undergoing chemotherapeutical treatments.
