Antifungal activity of liriodenine on clinical strains of Cryptococcus neoforma...
Levorato-Vinche,Adriele Dandara; Melhem,Marcia de Souza Carvalho; Bonfietti,Lucas Xavier; de-la-Cruz-Chacón,Iván; Boaro,Carmen Sílvia FernandesAbstract Background: Cryptoccocal meningitis continues to present high incidence among AIDS patients. The treatment of choice is the synergistic combination of flucytosine (5-FC) with amphotericin B deoxycholate (AmBd) or its lipid formulations. However, 5-FC is unavailable in many countries and AmB demands hospitalization. The combination of AmB with the fungistatic fluconazole (FLC) or the use of high FLC dai...
Oxidative metabolism altered by plant growth regulators in atemoia seeds (Annon...
Hata,Ana Paula Yuki; Ferreira,Gisela; Sousa,Marília Caixeta; Bezerra,Breno Kennedy Lima; Kissmann,CamilaAbstract The objective of this work was to validate the enzymatic activity in Annona x atemoyaseeds submitted to treatments with plant growth regulators belonging to the group of gibberellins and cytokinins for overcoming dormancy during the germination process. Initially, the water acquisition curve was determined, where two points of phase II (72 and 144 hours) were determined to evaluate the activity of supe...
Symptomatic burden amongst myeloproliferative neoplasm patients: MPN-10 prospec...
Sarmento,Maria; Ponte,Sandra; Monteiro,Maria José; Moura,Zilda; Ferreira,GiselaAbstract Introduction: Myeloproliferative neoplasms (MPN), including polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF), significantly impact patients’ quality of life (QoL). The symptom burden assessment and continuous monitoring using the MPN Symptom Assessment Form Total Symptom Score (MPN-10) allows detecting symptomatic changes that may be signs of disease progression and can be...
Changes in hormonal balance as key to reserve degradation after dormancy overco...
Ferreira,Gisela; De-la-Cruz-Chacón,Ivan; González-Esquinca,Alma RosaAbstract Studies on the effect of the applying of phytoregulators to overcome seed dormancy have been carried out in Annonaceae species, thus the endogenous relationship between abscisic acid and gibberellins after the application of phytoregulators needs to be known in these species. Considering the importance of hormonal balance in dormancy mechanisms, the aim of this research was to elucidate how endogenous ...
Antifungal activity of liriodenine on agents of systemic mycoses, with emphasis...
Vinche,Adriele Dandara Levorato; de- la-Cruz-Chacón,Iván; González-Esquinca,Alma Rosa; Silva,Julhiany de Fátima da; Ferreira,GiselaAbstract Background: Endemic systemic mycoses remain a health challenge, since these opportunistic diseases are increasingly infecting immunosuppressed patients. The simultaneous use of antifungal compounds and other drugs to treat infectious or non-infectious diseases has led to several interactions and undesirable effects. Thus, new antifungal compounds should be investigated. The present study aimed to evalu...
Propagation of Annonaceous plants
Ferreira,Gisela; De-La-Cruz-Chacón,Iván; Boaro,Carmen Silvia Fernandes; Baron,Daniel; Lemos,Eurico Eduardo Pinto deAbstract This review aims to present advances in studies on the propagation of the Annonaceae species, which includes species of economic importance such as: soursop, custard apple, atemoya and cherimoya. In sexual propagation, advances are mainly related to a better understanding of the stages of seed development, dormancy mechanisms, and germination. In asexual propagation, compatibility studies between graft...
Abscysic acid and compatibility of atemoya (Annona x atemoya Mabb.) grafted ont...
Baron,Daniel; Gimenez,Juliana Iassia; Ferreira,GiselaAbstract Grafting is an effective technique used in the cultivation of commercial fruit species given the necessity to guarantee the genetic characteristics of productive species using selected clones. Although grafting is a common and widespread technique and phytohormones play a key role in the formation of tissues, the relationship between phytohormones, such as abscisic acid, and mechanisms of incompatibili...
Seed quality of crambe (Crambe abyssinica Hochst) submitted to different drying...
Silva,Magnun Antonio Penariol da; Lima,Juliana Joice Pereira; Biaggioni,Marco Antonio Martin; Cavariani,Claudio; Ferreira,GiselaABSTRACT The objective of this research was to evaluate the effects of different drying methods on physiological quality of crambe seeds. Crambe seeds of FMS Brilhante cultivar were produced in the Lageado experimental farm (UNESP, Botucatu, Brazil) in 2012. The drying methods were: artificial drying with hot air, artificial drying with fresh air, natural yard drying, natural shade drying and natural field dryi...
Germinação de sementes de romäzeiras (Punica granatum L.) de acordo com a conce...
Takata,William; Silva,Ewerton Gasparetto da; Corsato,Jaqueline Malagutti; Ferreira,GiselaA romäzeira (Punica granatum L.) é fruteira de porte arbustivo, utilizada geralmente como planta ornamental e explorada quanto a suas características medicinais. Seus frutos apresentam cavidades internas onde estäo alojadas numerosas sementes e sem a presença de endosperma. Estas sementes apresentam certa dificuldade para germinar, sendo que se conseguiu atingir porcentagens satisfatórias de germinação com a ut...
Characterization of the chemical composition of the essential oils from Annona ...
Campos,Felipe Girotto; Baron,Daniel; Marques,Marcia Ortiz Mayo; Ferreira,Gisela; Boaro,Carmen Silvia FernandesThe objective of this study was to characterize the chemical composition of the essential oil from the leaves of Annona emarginata (Schltdl.) H. Rainer 'terra-fria' and Annona squamosa L. The species were grown in a greenhouse for 18 months, which nutrient solution was applied weekly; the plants were then harvested and the leaves dried to extract the essential oil. The essential oil was analyzed by gas chromato...
