1. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

2. Advances observed in papaya tree propagation
Resumo O mamoeiro (Carica papaya L.) é uma fruteira de bastante interesse econômico e alimentar em todo o mundo. Sua propagação pode ocorrer tanto por via sexuada como assexuada. Tradicionalmente é propagado por sementes, entretanto, a propagação vegetativa vem sendo frequentemente utilizada com o uso de técnicas de cultura in vitro e ex vitro. Na p

3. In Vitro Organogenesis from Root Explants of Passiflora miniata Mast., an Amazonian Species with Ornamental Potential
ABSTRACT The present study reports a shoot organogenesis-based system for in vitro regeneration of Passiflora miniata, an Amazonia passion fruit species. Root segments were cultured in Murashige and Skoog (MS) medium supplemented with different concentrations (range 2-9 µM) of 6-benzyladenine (BA); thidiazuron (TDZ) or kinetin (KIN). Plant growth regulators

4. Advances and challenges on the in vitro production of secondary metabolites from medicinal plants
RESUMO A produção de metabólitos secundários de plantas medicinais, também chamados de Compostos Medicinais Derivados de Plantas (PDMC), vem ganhando importância na última década. Concomitante ao aumento do conhecimento sobre as propriedades farmacológicas destes compostos, as plantas da horticultura tornam-se a fonte de biomassa mais importante, su

5. Micropropagation of Physalis peruviana L.
RESUMO Physalis peruviana L. (Solanaceae) é uma frutífera herbácea, que vem se consolidando no mercado em virtude de suas potencialidades nutricionais e medicinais. As limitações à sua produção são o ciclo reprodutivo curto, o acometimento dos frutos por pragas e a carência de estudos, o que justifica a busca de estratégias para a sua propagação

6. Gut: Key Element on Immune System Regulation
Abstract The gut is the main organ that mediates the contact between antigens with our organism, controlling the immune response against environmental factors, such as microbiota and food. Innate lymphoid cells participate in the gut-associated lymphoid tissue (GALT) maturation during the prenatal and early postnatal periods. After birth, breast milk provide

7. In vitro organogenesis and genetic transformation of mandarin cultivars
Resumo A organogênese in vitro das tangerinas Fremont (Citrus clementina x Citrus reticulata), Thomas (Citrus reticulata) e Nules (Citrus clementina) foi avaliada visando a otimizar o protocolo de regeneração para aplicação da transformação genética. O uso de explantes derivados de epicótilo resultou em maior número de explantes responsivos e maio

8. Propagación del banano: técnicas tradicionales, nuevas tecnologías e innovaciones
Abstract The different propagation systems for the banana: conventional or by tissue culture are reviewed. Conventional propagation, mainly using suckers, whole rhizomes or bits are still in use for familiar plantings or in farms for local markets in many tropical countries, while vitroplants are the rule in modern commercial banana cultivation. After exami

9. Investigation of the effect of gestational diabetes on fetal cardiac tissue in streptozotocin ınduced in rats
Abstract Purpose: To investigate the cause of congenital anomalies resulted from gestational diabetes on fetal cardiac tissue in experimental animal study model. Methods: Totally 12 female Wistar albino rats were divided into two groups, each consisting of 6 rats. Streptozotocin (60 mg/kg) was administered intraperitoneally to the study group by dissolving

10. Molecular basis of basal cell carcinoma
Abstract: Basal cell carcinoma is the most common cancer, presenting low mortality but high morbidity, and it has as risk factor exposure to sunlight, especially UVB spectrum. The most important constitutional risk factors for basal cell carcinoma development are clear phototypes (I and II, Fitzpatrick classification), family history of basal cell carcinoma

11. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

12. Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis
ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted
