Until recently, there has been a reluctance to apply arbitration and procedures agreements for lawsuits that might confront public interests. However, after the recent Brazilian arbitration law installment, this whole perspective seems to have changed. Hence, the use of arbitration forecasted in the legislative disposals has gained momentum due to the actual legislative proposals for further Brazilian public acquisitions – bidding law -, thus requiring higher competition from both national and foreign companies.

A adoção de novas tecnologias ocasionou mudanças expressivas no processo educacional promovendo novas maneiras de ensinar e aprender. Frente a esse paradigma, a tecnologia é um meio importante para melhorar a prática do ensino e da assistência de enfermagem. Realizou-se um estudo aplicado na modalidade de produção tecnológica, com fins de desenvolver e avaliar um aplicativo multimídia em dispositivos móveis para ensino dos procedimentos técnicos da práxis em Enfermagem.

Materiais eMétodos: Estudo descritivo, com abordagem qualitativa, realizado com quatro famílias de pacientes em cuidados paliativos vinculados a um hospital de referência em Recife-PE.

The insertion of everyday themes in Teaching Chemistry facilitates their contextualization and interdisciplinarity in the study of situations that involve themes related to agriculture and its potentialities. The productive activities in the chemical area are normally risky and potentially cause pollution, since it works with substances that often have toxic properties causing several environmental problems.

Introduction: Endodontic therapy aims to remove debris from the pulp tissue resulting from the preparation of the root and microorganisms of the root canal system channels, seeking cleaning and complete antisepsis. Also, the drug calcium hydroxide, Ca (OH) and good antimicrobial properties against the majority of endodontic-2 are used in endodontic treatment as intracanal pathogens relevant in tactical terms. Sodium hypochlorite is an irritant solution widely used in chemotherapeutic treatment for a long time with great effectiveness.

Introduction: Endodontic retraction is a procedure performed on a tooth that received an earlier attempt at a definitive treatment that resulted in a condition requiring additional new endodontic treatment to achieve a successful outcome. The major cause of treatment failure is insufficient cleaning and inadequate obturation. Objective: was to evaluate, through a literature review, the endodontic retreatments with rotary and mechanical files, which is the best efficacy.

The antitumoral activity of plants containing quinonic compounds has been reported, however there is a need to evaluate Eleutherine plicata. This study assesses the impact of E. plicata fractionation in its antitumoral effect. The ethanol extract obtained from E. plicata bulbs (EEEP) was fractionated under reflux. The dichloromethane fraction (FRDCM) was refracted in a chromatographic column, isolating eleutherol, isoeleutherin and eleutherin.

The rapid growth of cities worldwide, particularly in developing countries, has increased chronic degenerative diseases, such as diabetes, obesity, metabolic syndrome, and cardiovascular diseases. Several medicinal plants such as Moringa oleifera have been considered to be used in a plethora of health conditions since they possess many properties, including antioxidant, anticancer, antidiabetic, anti-inflammatory, and antihypertensive actions and the ability to protect against liver damage. This study aimed to review the effects of Moringa oleifera on human health.

The objective of this work was to carry out an investigation regarding phytochemical prospecting of six extracts obtained from leaves of Myrcia palustris DC, namely: ethyl acetate (EAE), acetone (AE), ethanolic (EE), methanolic (ME), hexanic (HE) and distilled water (DAE), to evaluate their antimicrobial activity using the broth microdilution technique, with bacteria of medical interest, and detecting the antioxidant potential against the 2,2-diphenyl-1-picryl-hydrazil (DPPH) method.

Sprouting of potato tubers occurs over a prolonged storage, even at low temperatures, making tubers unsuitable for the processing industry. The application of sprouting inhibitors is an alternative; however, commercial compounds are toxic, making necessary the study of natural inhibitors, such as menthol and hydrogen peroxide (H2O2). The objective of this study was to evaluate the response menthol and hydrogen peroxide treatments on the physiology of sprouted tubers of ‘Markies’ potatoes in refrigerated storage for frying.
