Fishers' knowledge and seahorse conservation in Brazil
Ierecê ML Rosa, R?mulo RN Alves, Kallyne M Bonifácio, José S Mour?o, Frederico M Osório, Tacyana PR Oliveira, Mara C Nottingham
Journal of Ethnobiology and Ethnomedicine , 2005, DOI: 10.1186/1746-4269-1-12
Abstract: Over a decade ago, Ruddle [1] pointed out the great potential value of local knowledge as an information base for local management of marine environments and resources, especially in the tropics, where conventionally-used data were usually scarse to non-existent. A number of subsequent studies have documented and recognized the value of local knowledge to conservation and management of fisheries [2-12].A pragmatic view of the relevance of fishers knowledge to fisheries management has been expressed by Ames [8]: "fishermen and their subjective, anecdotal descriptions have a pivotal role to play in the development and function of sustainable fisheries (.......) fishermen are, in fact, the only available source of local, historical, place-based information". Nevertheless, lack of sound management practices have led to the collapse of particular types of fisheries in some parts of the world, and, as pointed out by Meewig et al. [13], interest in participatory approaches in resource management in part reflects the failure of top-down, centralized approaches to manage natural resources.Definitions of artisanal, subsistence fisheries have traditionally focused on the capture and trade of food fish. However, a growing number of examples of fish species being traded worldwide for purposes other than alimentary (e.g., as pets, remedies, souvenirs) has revealed the existence of an international and multi-faceted commerce, supported by a diffuse (and generally poorly quantified) harvesting of a number of species.Those forms of exploitation have received little attention when compared with the trade of animals for alimentary purposes [14]. In the marine realm, the scarcity of data has rendered the identification of key elements for conservation and management, and the assessment of impacts difficult.Seahorses (Hippocampus spp.) are among the few non-food marine fishes whose trade has been documented, initially in Asia [15], where the demand for those fishes was primarily for use
Novel sex-related characteristics of the longsnout seahorse Hippocampus reidi Ginsburg, 1933

Abstract: this paper presents novel sex-related characteristics in hippocampus reidi, expressed as a prominent and pigmented keel (males only), and by a row of dorsolateral spots mostly (97.4%) found in males. while the keel was found even in the smallest males sampled, the dorsolateral spots appear to be associated with body size. ex situ observations revealed that during courtship males highlighted both characters by turning pale their background body colour. understanding such colour and behavioural patterns is relevant to increase our knowledge about sexual selection in a morphologically and biologically unique group of fishes.

First record of the olive bud mite Oxycenus maxwelli (Keifer) (Acari: Eriophyidae) from Brazil
Reis, PR;Oliveira, AF de;Navia, D;
Neotropical Entomology , 2011, DOI: 10.1590/S1519-566X2011000500017
Abstract: the mite oxycenus maxwelli (keifer) (eriophyidae) is reported for the first time in brazil infesting olive trees, olea europaea. specimens were found on seedlings at maria da fé, state of minas gerais, in 2007. although minor symptoms were not noticed, significant damage to plants were observed. there is no reliable evidence of when the mite could have been introduced. it is believed that the mite occurs since the first introductions of olive trees, around 1820, through vegetative propagating material, but the mite remained unnoticed due to the lack of studies with olive trees in brazil.

Abstract: this paper presents the results of the first analysis of the natural diet of hippocampus reidi, one of the most sought after seahorse species in the international aquarium trade. its main goals were to investigate food items and prey categories consumed by the species, and to discuss feeding strategy and inter and intra-individual components of niche breadth. data were gathered from october 2005 to september 2006 at the mamanguape estuary, state of paraíba, ne brazil. food items from seahorses anaesthetized with clove oil were obtained by using a modified version of the flushing method, and were counted and identified to the lowest possible taxonomic level. specimens were marked and had their height, sex, life and reproductive stage recorded, and then returned to the same place where they were found for the further assessment of anaesthetization/gut flushing on seahorses. food items were analyzed using frequency of occurrence, relative abundance, index of preponderance and prey-specific abundance using the points method. the graphic method of amundsen et al. (1996) was used to interpret the feeding strategy and contribution to niche breadth. nematodes and crustaceans were the most important items found, the latter item usually being the most commonly found in the gut contents of syngnathids. no significant differences in diet composition were found between reproductive stages, however, a higher proportion of large items were consumed by the larger seahorses. the feeding strategy and niche breadth analysis suggests that h. reidi has a generalist feeding strategy, with high variation between phenotypes. our results suggest that the anaesthetization-flushing technique has the potential to be a useful tool in seahorse research.

Abstract: Ana Lucia Lei Munhoz Lima, Priscila Rosalba D de Oliveira, Perola Grimberg Plapler, Flora Maria D Andrea Marcolino, Eduardo de Souza Meirelles, André Sugawara, Riccardo Gomes Gobbi, Alexandre Leme Godoy dos Santos , Gilberto Luis CamanhoInstitute of Orthopedics and Traumatology, Hospital das Clínicas, University of S o Paulo School of Medicine, S o Paulo, BrazilAbstract: Increasing bone mineralization abnormalities observed among people living with HIV (PLWHIV) result from various factors relating to the host, the virus, and the antiretrovirals used. Today, HIV infection is considered to be a risk factor for bone mineralization disorders. The test most recommended for diagnosing osteoporosis is measurement of bone mineral density by means of dual energy X-ray absorptiometry at two sites. Osteoporosis treatment has the aims of bone mass improvement and fracture control. A combination of calcium and vitamin D supplementation may reduce the risk of fractures. Antiresorptive drugs act by blocking osteoclastic activity and reducing bone remodeling. On the other hand, bone-forming drugs stimulate osteoblastogenesis, thereby stimulating the formation of bone matrix. Mixed-action medications are those that are capable of both stimulating bone formation and inhibiting reabsorption. Antiresorptive drugs form the group of medications with the greatest quantity of scientific evidence confirming their efficacy in osteoporosis treatment. Physical activity is a health promotion strategy for the general population, but only preliminary data on its real value and benefit among PLWHIV are available, especially in relation to osteoporosis.Keywords: osteoporosis, HIV/AIDS, diagnosis, treatment, exercise

Infection and Drug Resistance , 2011,
Abstract: Priscila R Oliveira1, Adriana P Paula1, Karine Dal-Paz1, Cassia S Felix1, Flavia Rossi2, Jorge S Silva1, Ana Lucia M Lima11Orthopaedics and Traumatology Department, 2Pathology Department, University of S o Paulo, S o Paulo, BrazilIntroduction: In recent decades, antimicrobial resistance has become a public health problem, particularly in cases of healthcare-associated infections. Interaction between antibiotic consumption and resistance development is of particular interest regarding Gram-negative bacilli, whose growing resistance has represented a great challenge.Objective: Assess the impact of restriction of cefepime use on antimicrobial susceptibility among the Gram-negative bacilli (GNB) most frequently involved in healthcare-associated infections (HAI).Methods: Data relating to hospital occupancy and mortality rates, incidence of HAI, incidence of GNB as causative agents of HAI, antimicrobial consumption at the hospital and antimicrobial susceptibility of GNB related to HAI were compared between two periods: a 24-month period preceding restriction of cefepime use and a 24-month period subsequent to this restriction.Results: There was a significant drop in cefepime consumption after its restriction. Susceptibility of Acinetobacter baumanii improved relating to gentamicin, but it worsened in relation to imipenem, subsequent to this restriction. For Pseudomonas aeruginosa, there was no change in antimicrobial susceptibility. For Klebsiella pneumoniae and Enterobacter spp, there were improvements in susceptibility relating to ciprofloxacin.Conclusion: Restriction of cefepime use had a positive impact on K. pneumoniae and Enterobacter spp, given that after this restriction, their susceptibilities to ciprofloxacin improved. However, for A. baumanii, the impact was negative, given the worsening of susceptibility to imipenem.Keywords: ecological studies, cross infection, drug resistance, microbial, Gram-negative bacilli, cefepime
Generalization of the Second Order Vector Potential Formulation for Arbitrary Non-Orthogonal Curvilinear Coordinates Systems from the Covariant Form of Maxwell's Equations  [PDF]
Denis Prémel
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2012, DOI: 10.4236/jemaa.2012.410055
Abstract: A great number of semi-analytical models, notably the representation of electromagnetic fields by integral equations are based on the second order vector potential (SOVP) formalism which introduces two scalar potentials in order to obtain analytical expressions of the electromagnetic fields from the two potentials. However, the scalar decomposition is often known for canonical coordinate systems. This paper aims in introducing a specific SOVP formulation dedicated to arbitrary non-orthogonal curvilinear coordinates systems. The electromagnetic field representation which is derived in this paper constitutes the key stone for the development of semi-analytical models for solving some eddy currents moelling problems and electromagnetic radiation problems considering at least two homogeneous media separated by a rough interface. This SOVP formulation is derived from the tensor formalism and Maxwell’s equations written in a non-orthogonal coordinates system adapted to a surface characterized by a 2D arbitrary aperiodic profile.
