Suporte básico de vida em Medicina Dentária

As emergências no consultório dentário são ocorrências raras, mas podem ser suficientemente graves e colocar em risco a vida do paciente. O médico dentista deve estar capacitado para reconhecer alterações no paciente que podem ser desde uma síncope até uma paragem cardiorrespiratória onde será necessário utilizar o Suporte Básico de Vida (SBV) para salvar a vida ou limitar danos ao paciente. Apesar da formação recebida, muitos profissionais não se sentem preparados para realizar o SBV. O objetivo desta revisão bibliográfica foi abordar os aspectos mais importantes e atuais do SBV com ênfase na importância da formação atualizada e contínua do médico dentista e sua equipa para que promovam uma correta e segura utilização do SBV ao surgir uma emergência clínica. A conclusão principal é que o SBV conduzido por uma equipa treinada evita complicações e aumenta a sobrevivência dos pacientes nas emergências.Emergencies in the dental office are very rare incidents, but they can be severe enough to endanger the patient's life. The dentist should be able to recognize changes in vital signs which may be the result of syncope or even cardiorespiratory arrest. In the latter instance it will be necessary to perform Basic Life Support (BLS) to save the life of the patient. Despite the training received, many professionals feel unprepared to start BLS. The objective of this literature review was to address the most important and current aspects of BLS with emphasis on the importance of continuous training of the dentist and his team to promote the correct and safe use of BLS when a clinical emergency arises. The main conclusion is that BLS conducted by a trained team avoids complications and increases patient survival in emergencies

Pedagogical conditions for the development of cognitive independence in physical education lessons

Cognitive Independence (CI), which physical education has a high potential for fostering in students, is characterized by a developed set of cognitive skills, an ideal level of knowledge, a strong value attitude towards cognition, and competencies related to the ability and willingness to take the initiative and engage in professionally responsible activities. However, the biggest challenges for physical education teachers stem from a lack of program material that clearly defines the content of lessons for the development of students’ CI as well as the stages of their entrance into the educational process. The purpose of the study is to theoretically justify and methodologically support the process of developing students’ CI in physical education lessons. The methodology used in the study comprises a quasi-experimental pretest-posttest research design. The study participants included 210 students in grades 10 and 11 from two secondary schools in the city of Atyrau (the Republic of Kazakhstan) and teachers acting as experts. The study findings revealed substantial variations in the dynamics of students’ CI in the control and experimental groups, confirming the efficiency of the application of the built-in model and technology. Despite the limitations, which lie in the fact that not all aspects of the development of students’ CI in physical education lessons were considered, this study has provided the theoretical justification and methodological support for development of students CI in physical education lessons that might contribute to efficient specialists’ training

PECULIARITIES OF THE MICROFLORA OF BREAST MILK AND FACTORS OF NON-SPECIFIC RESISTANCE OF FEEDING WOMEN

Date, it is believed that the natural feeding of the newborn is the most optimal and physiological for the full development of the newborn. Immunity against enterobacteria causing diarrheal diseases is mainly carried out by igm. This immunoglobulin does not cross the placenta, so babies are not protected against intestinal infections. Relationship between microflora and the immune system, the aim of our work was to study the microbial landscape of breast milk of nursing women with a parallel study of the level of iga, g, m and siga in breast milk. 914 breast-milk samples of lactating women were studied in a bacteriological laboratory of center for urban sanitary and epidemiological surveillance and center for railway station sanitary and epidemiological surveillance of urgench city

Kinetics and mechanism of triphenylphosphine quarternization with unsaturated carboxylic acids in the medium of acetic acid

Kinetics of reaction of triphenylphosphine with a series of unsaturated carboxylic acids and related esters in the medium of acetic acid as well as in mixtures of acetic acid and acetonitrile was studied by spectrophotometry. The data obtained show that the process of quarternization should be described by kinetic equation of third order, the proton transfer occurs from the solvent. A stepwise mechanism of interaction including formation of prereaction complex on the reaction pathway is proposed. © 2009 Pleiades Publishing, Ltd

Synthesis of carboxylate arsenobetaines based on (carboxyalkyl)triphenylarsonium halides

© 2015 Pleiades Publishing, Ltd. It has been found that the reaction of triphenylarsine with unsaturated carboxylic acids (acrylic, maleic, and itaconic ones) supposed to yield the arsenobetaines does not occur, in contrast to similar reactions of carboxylic acids with tertiary phosphines. However, the interaction of tertiary arsines with the halogenated carboxylic acids has resulted in the corresponding tertiary arsonium salts, dehydrohalogenation of the latter affording the target carboxylate betaines in the quantitative yield; the products structure has been elucidated using a set of chemical, physical, and physico-chemical methods. Antibacterial activity of the prepared compounds has been studied

Kinetics and mechanism of quaternization of tertiary phosphines with unsaturated carboxylic acids. Kinetic studies of the reactions in aprotic solvents

Data obtained while studying the kinetics of quaternization of tertiary phosphines with the unsaturated carboxylic acids in the series of aprotic solvents indicate the participation of a second molecule of acid playing the part of the external proton donor in this process. Quantitative analysis of the effect of solvent within the frames of the Koppel-Palm equation showed that the main contribution in the reaction rate belongs to the nucleophilicity of medium while the effects of polarity and electrophilicity are smaller. The results obtained suggest the step-by-step mechanism of interaction including the formation of the zwitterionic intermediate on the reaction pathway common for the solvents with different proton activity. © Pleiades Publishing, Ltd., 2011

The synthesis and reactions of betaines formed in reactions of tertiary phosphines with unsaturated carboxylic acids and their derivatives

On the basis of our systematic investigations, the main trends concerning synthesis, structure, and reactivity of carboxylate phosphabetaines - phosphorus analogs of organic aminoacids - are considered and analyzed. A wide series of phosphabetaines has been obtained in reactions of tertiary phosphines with unsaturated mono- and dicarboxylic acids, and also with their derivatives - esters and amides. By a plethora of experimental and theoretical methods, it has been shown that the thermodynamic stability of carboxylate phosphabetaines essentially depends on the structure of the initial phosphine and carboxylic acid. In some cases, the reaction between them is equilibrated. On the other hand, for a number of synthesized betaines, it is reliably established that these exist in equilibrium with isomeric phosphoranes. The extremely important condition for stabilization of phosphabetaine structures is the presence of proton-donating reagents, which are included in their crystal lattice. In the series of symmetrically substituted derivatives, the interesting phenomenon of phosphorotropy of the phosphonium group is established. The reactivity of phosphabetaines in reactions with electrophilic reagents (haloid alkyls and acyls, isocyanates, corbodiimides) has been investigated. The majority of key structures have been confirmed by the direct X-ray method. © 2006 Wiley Periodicals, Inc
