New types of bialgebras arising from the Hopf equation

New types of bialgebras arising from the Hopf equation (pentagonal equation) are introduced and studied. They will play from the Hopf equation the same role as the co-quasitriangular do from the quantum Yang Baxter equation.Comment: Latex2e, Comm Algebra, in pres

The Hopf modules category and the Hopf equation

We study the Hopf equation which is equivalent to the pentagonal equation, from operator algebras. A FRT type theorem is given and new types of quantum groups are constructed. The key role is played now by the classical Hopf modules category. As an application, a five dimensional noncommutative noncocommutative bialgebra is given.Comment: 30 pages, Letax2e, Comm.

Hallazgo inmunohematológico anticipala refractariedad al tratamiento con daratumumab en paciente con mieloma múltiple

Daratumumab (DARA) is a human monoclonal antibody that targets CD38. It is used for the treatment of patients with refractory/relapse multiple myeloma. DARA interferes with immunohematological tests, causing positive agglutination reactions in indirect antiglobulin tests, antibody screening tests and crossmatches, from the beginning of the treatment until several months after finished.We describe the case of a 65-years old patient with relapsed multiple myeloma treated with DARA. It was confirmed positivization in its immunohematological tests as planned, but evolving with a premature and unexpected negativization. The patient was refractory to this treatment. This atypical immunohematological finding could be due to the development of anti-DARA antibodies.El daratumumab (DARA) es un anticuerpo monoclonal humano de especificidad anti-CD38, utilizado en el tratamiento de pacientes que padecen mieloma múltiple recaído/refractario. Es conocido que este medicamento interfiere en las pruebas inmunohematológicas séricas, positivizando en medio antiglobulínico tanto la investigación de anticuerpos irregulares como las pruebas de compatibilidad transfusional, desde el inicio del tratamiento hasta varios meses después de su finalización. Se describe el caso de una paciente de 65 años con diagnóstico de mieloma múltiple en recaída, que fue sometida a tratamiento con DARA. Se constató en sus pruebas inmunohematológicas séricas que se habían positivizado según es habitual, una prematura e inesperada negativización. La paciente fue refractaria al tratamiento con DARA. Se piensa que nuestro hallazgo inmunohematológico atípico podría haber estado vinculado al desarrollo de anticuerpos anti-DARA

Plantas medicinais cultivadas em quintais de comunidades rurais no domínio do cerrado piauiense (Município de Demerval Lobão, Piauí, Brasil) Medicinal plants cultivated in homegardens of rural communities in the domain of Cerrado in Piaui (Demerval Lobão Municipality, Piauí State, Brazil)

O conhecimento terapêutico acumulado por populações rurais através de séculos de estreito contato com o meio possibilita a obtenção de informações acerca do uso dos recursos naturais. O objetivo do presente trabalho foi realizar um inventário das plantas medicinais cultivadas em quintais do município de Demerval Lobão, Piauí, bem como, conhecer o emprego e a importância dessas espécies na comunidade. Foram amostrados 21 quintais em nove comunidades da zona rural do município de Demerval Lobão com vegetação de cerrado. O trabalho foi conduzido com os mantenedores dos quintais a partir de entrevistas semi-estruturadas e observação direta, associada à técnica de turnê-guiada. As plantas medicinais coletadas foram catalogadas, identificadas, e depositadas no Herbário Graziela Barroso (TEPB) da Universidade Federal do Piauí (UFPI). Foram referidas 100 espécies botânicas, predominantemente herbáceas e cultivadas, distribuídas em 49 famílias, sendo Leguminosae, Euphorbiaceae e Lamiaceae as mais representativas em número de espécies. Na preparação dos remédios, as folhas foram as mais utilizadas, sendo a decocção a principal forma de preparo. As doenças mais frequentes tratadas por remédios caseiros referem-se ao sistema respiratório e digestivo. Observou-se que não há rigidez quanto à posologia e a duração do tratamento, ficando este a critério do hábito de cada pessoa entrevistada. As plantas que apresentaram índice de importância relativa e concordância de uso (CUP) acima de 60% foram cansansão (Cnidosculus urens), boldo (Plectranthus barbatus Andrews), jurema-preta (Mimosa verrucosa Benth) e cidreira (Lippia alba (Mill.) N.E.Br. ex Britton & P.Wilson). P. barbatus foi a mais citada e também a que apresentou os índices mais altos de CUP (100%), fator de correção - FC (1,00) e concordância de uso corrigido - CUPc (100%) para dores no estômago e problemas no fígado. Observou-se a necessidade de resgatar o conhecimento acerca das plantas medicinais para contribuir na melhoria da qualidade de vida dos moradores da zona rural, como primeiro passo para a valorização e adequação dos recursos da medicina popular para o tratamento de doenças mais frequentes.<br>Therapeutic knowledge accumulated by rural populations, through centuries of direct contact with the environment, makes possible the gathering of information concerning use of natural resources. The aim of the present study was to carry out an inventory of the medicinal plants cultivated in homegardens of Demerval Lobão Municipality, Piauí State, Brazil, as well as to learn their uses and importance in the community. A total of 21 homegardens in nine communities of the rural area of Demerval Lobão Municipality with Cerrado vegetation were sampled. The study was conducted by means of semi-structured interviews and direct observation, associated with the technique of a tour guided by the keepers of the homegardens. The collected medicinal plants were cataloged, identified and deposited in the Herbarium Graziela Barroso (TEPB) of Federal University of Piauí (UFPI). Of 100 botanical species, predominantly herbaceous and cultivated species distributed in 49 families, were cited, and the most representative families in number of species were Leguminosae, Euphorbiaceae and Lamiaceae. For the preparation of medicines, leaves were most used and decoction was the main form of preparation. The most frequent diseases treated by homemade remedies are associated with the respiratory and digestive systems. There is no rigidity as to dosage and duration of treatment; it depended on the habit of each interviewed person. The plants that presented an index of relative importance and use agreement above 60% were the following: "cansansão" (Cnidosculus urens), "boldo" (Plectranthus barbatus Andrews), black-jurema (Mimosa verrucosa Benth) and "cidreira" (Lippia alba (Mill.) N.E.Br. ex Britton & P.Wilson). P. barbatus was most cited and also the species that presented the highest indices of CUP (100%), FC (1,00) and CUPc (100%) for stomach pains and liver problems. There is the need of rescuing knowledge concerning medicinal plants to contribute to the improvement of the life quality of the inhabitants of the rural area, as a first step for the appreciation and adaptation of resources of folk medicine for the treatment of the most frequent diseases
