Inoculation of arbuscular mycorrhizal fungi as a strategy to improve annatto (Bixa orellana L. ) growth

This study aimed to assess the occurrence of arbuscular mycorrhizal fungi (AMF) in annatto (Bixa orellana L.) cultivars and their response to AMF inoculation using biometric parameters. The occurrence surveys were conducted in annatto fields in three municipalities from Pernambuco Forest Zone: Lagoa de Itaenga, Gloria de Goitá, and Vitoria de Santo Antão, and in four cultivars (Red Piave, Green Piave, Red Peruvian Paulista, and Green Peruvian Paulista). In a greenhouse, biometric parameters of annatto seedlings of Red Piave, Red Peruvian Paulista, Embrapa-36, and Embrapa-37 cultivars inoculated with AMF isolated from annatto fields. The Red Piave cultivar exhibited greater root colonization than the Green Peruvian Paulista in the Lagoa de Itaenga and Vitoria de Santo Antão municipalities. The cultivar Red Piave showed a more beneficial association with AMF in plants and soil than cultivar Green Peruvian Paulista did, in both Lagoa de Itaenga and Vitoria de Santo Antão. AMF inoculation was effective in promoting the growth of annatto plants, particularly those inoculants with S. heterogama and C. etunicatum.

Integrative research identifies 71 new plant species records in the state of Rio Grande do Norte (Brazil) and enhances a small herbarium collection during a funding shortage.

A National Forest Inventory (NFI) encompassing the entire territory of Brazil is in progress. It is coordinated and promoted by the Brazilian Forest Service of the Ministry of Environment. In each state, the NFI collaborates with local herbaria by receiving collected plant material and performing species identification. Consultants are hired by the NFI and work at the local herbaria under the supervision of a curator. In exchange for curatorial assistance, the NFI provides equipment and consumables for the herbarium. Other public projects collaborating with NFI are Reflora and the Brazilian Biodiversity Information System (SiBBr). Both projects have online platforms that seek to connect herbaria and make all their data freely available, including high quality digital images of specimens. Through inter-institutional collaboration, the joint interests of NFI, Reflora, SiBBr and local herbaria have improved collections, expanded the online Reflora database, and provided the NFI with verified species lists. These strategic uses of public funding are positively affecting Botany, particularly during a period of economic crisis and cuts in research. Here, we illustrate the increase in floristic knowledge through the improvement of a herbarium collection in Rio Grande do Norte (RN) - the Brazilian state with the lowest levels of plant richness. We report 71 new occurrences of vascular plants for RN, belonging mainly to the Poaceae, Fabaceae and Malvaceae. Most of the species with new occurrences have a Neotropical distribution (21 spp.) and only seven are restricted to the Brazilian Northeast. Our findings highlight previous gaps in RN's floristic knowledge. The partnership NFI, Reflora, SiBBr and the UFRN herbarium improved herbarium curation, digital collection, and quality of data. Finally, a fellowship provided by Reflora and SiBBr allowed improving curation by distributing duplicates and incorporating the Herbarium of Câmara Cascudo Museum.

Origin of the tendon of the long head of the biceps brachii muscle and its relationship with glenoid labrum in human foetuses / Origen del tendón de la cabeza larga del bíceps braquial y sus relaciones con el labro glenoideo en fetos humanos

We dissected the shoulders of 20 human foetuses to anatomical study. The purpose of this study was to characterize the anatomical origin of the long head tendon of the muscle biceps brachii (LHBBT) in human foetuses and its relationships with the glenoid labrum of the scapula. The results had shown that in approximately 95 percent of the cases the tendon of the long head of the biceps brachii inserts in the region of the glenoid labrum. This origin seems to form, together with the glenoid labrum, an anatomical complex. We conclude that the almost totality of the LHBBT was originated in the glenoidal labrum. For us, this furthermore reinforce the importance and necessity of better clarifying the anatomical and clinical implications of the biceps/labrum complex.

Fueron disecados los hombros de 20 fetos humanos con el propósito de hacer un estudio anatómico. El objetivo de este estudio fue cdeterminar el origen del tendón de la cabeza larga del músculo bíceps braquial en fetos humanos y sus relaciones con el labro glenoideo. Los resultados demostraron que, en cerca del 95 por ciento de los casos, el tendón de la cabeza larga del músculo bíceps braquial estaba originándose en la región del labro glenoideo. Este origen parece formar junto, con el labro glenoideo, un complejo anatómico. Concluimos que casi todos de los tendones del músculo bíceps braquial están insertados en el labro glenoideo. Esto es importante conocer para una mejor clarificación de las implicaciones clínico-anatómicas del complejo del bíceps/labro.

Compreendendo os problemas em relação ao uso de medicamentos em uma comunidade atendida pelo PSF: desdobramentos para o enfermeiro

Trata-se de uma pesquisa de campo, realizada na cidade de Santa Rita de Cássia-BA, em julho de 2004, por meio de um formulário com 21 questões relacionadas ao uso de medicamentos, com uma amostra de 62 pessoas. Dos entrevistados, os que tinham o 1º grau incompleto e os analfabetos compunham 65 por cento; 34 por cento dos entrevistados liam a bula e apenas 12,9 por cento dos mesmos a entendiam; 91,9 por cento ganhavam na época da pesquisa de 1 a 1,5 salário mínimo; destes, 29,4 por cento abandonavam o tratamento farmacológico por questões econômicas. A falta de informação, a cultura e os fatores socioeconômicos da amostra influenciam no uso de medicamentos e no abandono/adesão ao mesmo. O principal problema levantado foi o baixo grau de escolaridade. As ações do enfermeiro do PSF, nesta região, deverão estar relacionadas para a promoção do uso racional dos medicamentos.(AU)
