Abstract: Preliminary morphologic and morphometric study of the encephalon of the tiburoncito Ariopsis seemanni (Pisces: Ariidae)Objective. To describe morphologically and morphometrically the encephalon of Ariopsis seemanni. Materials and methods. We workedwith 10 juvenile specimens which were processed according to the ethical standards for handling fish. Measurements of the total andstandard length (cm) and weight (g) were taken for each individual. Specimens were fixed in 4% formaldehyde. The encephalon wasremoved, the different regions were identified and the measurement of the different lobes was done, indicating their location, morphology,length and area using lateral, dorsal and ventral digitalized images that were measured with the Scion Image program. We calculated meansand standard deviations, and obtained the percentage equivalence of each structure in relation to the entire encephalon. These data were thenrelated to the habits of the species. Results. We identified the olfactory bulbs, telencephalic hemispheres, optic lobes, cerebellum, amongothers. Of the cranial nerves, only the optic nerve was observed. The largest structure of the encephalon is the cerebellum (44 ± 1.2% and0.23 ± 0.03 cm2 area), followed by the telencephalic hemispheres (28 ± 0.57% and 0.13 ± 0.02 cm2 area). Conclusions. The encephalonmorphology of A. seemanni presented the general pattern of teleosts of the order Siluriformes, with the cerebellum as the largest structureof the encephalon. Based on the morphology and morphometry observed in the encephalon, we suggest that A. seemanni uses primarilyvision and taste to explore the environment.

Abstract: As sub-Saharan African countries continue to scale up antiretroviral treatment, there has been an increasing emphasis on moving provision of services from hospital level to the primary health care clinic level. Delivery of antiretroviral treatment at the clinic level increases the number of entry points to care, while the greater proximity of services encourages retention in care. In Tete City, Mozambique, patients on antiretrovirals were rapidly down referred from a provincial hospital to four urban clinics in large numbers without careful planning, resulting in a number of patients being lost to follow-up. We outline some key lessons learned to support down referral, including the need to improve process management, clinic infrastructure, monitoring systems, and patient preparation. Down referral can be avoided by initiating patients' antiretroviral treatment at clinic level from the outset.

Abstract: this study analyzed the involvement of teta and tete genes in the tetracycline resistance of 16 strains of genus aeromonas, isolated from clinical and food sources. polymerase chain reactions revealed that 37.5% of the samples were positive for teta, and also 37.5% were tete positive. one isolate was positive for both genes. only the isolate a. caviae 5.2 had its resistance associated to the presence of a plasmid, pss2. the molecular characterization of pss2 involved the construction of its restriction map and the determination of its size. the digestion of pss2 with hindiii originated two fragments (a and b) that were cloned separately into the puc18 vector. the teta gene was shown to be located on the hindiii-a fragment by pcr. after transforming a tetracycline-sensitive strain with pss2, the transformants expressed the resistance phenotype and harbored a plasmid whose size was identical to that of pss2. the results confirmed the association between pss2 and the tetracycline resistance phenotype, and suggest a feasible dissemination of teta and tete among strains of aeromonas. this study suggests the spreading teta and tete genes in aeromonas in brazil and describes a resistance plasmid that probably contributes to the dissemination of the resistance.

Abstract: In spite of the abundance and commercial importance of these two species, there is little published weight-length data for the gafftopsail catfish (Bagre marinus) and hardhead catfish (Ariopsis felis). For this study 84 catfish were caught (hook and line) from the Calcasieu Estuary in Southwest Louisiana near the Gulf of Mexico and estuaries and near shore waters close to bayou Lafourche. Using least squares regression, best fit curves were determined for weight (W) vs. total length (L) relationships in gafftopsail catfish, W(L) = 1000(L/484.73)^3.2660, while the best-fit equation for the hardhead was W(L) = 1000(L/469.53)^3.0188, where W is the weight in grams and L is the total length in millimeters. Results showed that, when compared to gafftopsail and hardhead catfish caught in Florida, Louisiana gafftopsail catfish tend to weigh less at similar lengths; whereas, the Louisiana hardhead catfish tend to weigh about the same. Results also show that the total length (TL) can be related to the fork length (FL) as TL = 1.184 FL in gafftopsail catfish with R^2 = 0.9922 and TL = 1.140 FL with R^2 = 0.9667 in hardhead catfish.

Abstract: this paper analyzes notions of aesthetics and eroticism and the ways these mould how women in tete province, in mozambique prepare their body. focus group and individual interviews allowed to assess that women use different products both natural and synthetic by insertion in their vagina or by ingestion to modify the way they feel their body and prepare themselves for the sexual act. in addition, the majority of women elongate their labia minora (small vaginal lips) since their childhood, modifying their body accordingly to aesthetic criteria, notions of femininity and sexual pleasure. these interventions are part of a process of socialisation integrating components on aesthetic, sexuality, reproduction and life in general. this paper aims at showing the importance of metaphors and of the notions of closing up/open, dryness/ wetness, hot/cold, heavy/light, life/death, wealth/poverty, sweet/ non-sweet as gendered symbols related to eroticism and aesthetic.
Evidence for Magnetoreception in Red Drum (Sciaenops ocellatus), Black Drum (Pogonias cromis), and Sea Catfish (Ariopsis felis)  [PDF]

Quantitative Biology , 2015,
Abstract: Over the past few decades, magnetoreception has been discovered in several species of teleost and elasmobranch fishes by employing varied experimental methods including conditioning experiments, observations of alignment with external fields, and experiments with magnetic deterrents. Biogenic magnetite has been confirmed to be an important receptor mechanism in some species, but there is ongoing debate regarding whether other mechanisms are at work. This paper presents evidence for magnetoreception in three additional species, red drum (Sciaenops ocellatus), black drum (Pogonias cromis), and sea catfish (Ariopsis felis), by employing experiments to test whether fish respond differently to bait on a magnetic hook than on a control. In red drum, the control hook outcaught the magnetic hook by 32 - 18 for chi-squared = 3.92 and a P-value of 0.048. Black drum showed a significant attraction for the magnetic hook, which prevailed over the control hook by 11 - 3 for chi-squared = 4.57 and a P-value of 0.033. Gafftopsail catfish (Bagre marinus) showed no preference with a 31 - 35 split between magnetic hook and control for chi-squared = 0.242 and a P-value of 0.623. In a sample of 100 sea catfish in an analogous experiment using smaller hooks, the control hook was preferred 62-38 for chi-squared = 5.76 and a P-value of < 0.001. Such a simple method for identifying magnetoreceptive species may quickly expand the number of known magnetoreceptive species and allow for easier access to magnetoreceptive species and thus facilitate testing of magnetoreceptive hypotheses.

Abstract: Se analizó el contenido de metales pesados en tejido muscular del bagre, Ariopsis felis en el sur del golfo de México durante el período 2001-2004. La investigación fue efectuada buscando establecer un marco de referencia ambiental para este organismo. La concentración metálica siguió el orden: Hg < Co < Pb < Ni < V < Cr. Fue observado un decremento en contenido de cobalto y vanadio, incremento en contenido de níquel, mercurio y cromo, y ausencia de estos comportamientos para contenido de plomo. Análisis de varianza de una sola vía confirman variación temporal significativa sólo en cobalto, mercurio, plomo y vanadio. Se determinaron coeficientes de correlación lineal significativos (p ≤ 0,05) para Co-V, Cr-Ni, Cr-Pb, Co-Hg, Ni-V y V-Pb. Las tres primeras asociaciones mostraron correlación positiva y las restantes correlación negativa. El análisis factorial reveló agrupamiento de los metales estudiados en función de su origen. Niveles de metales inferiores a los establecidos en normas nacionales e internacionales fueron encontrados en tejido muscular de A. felis del sur del golfo de México. We analyzed the heavy metal content in the muscular tissue of the catfish, Ariopsis felis, in the southern Gulf of México between 2001 and 2004. The research was done in order to establish an environmental frame of reference for this organism. The metal concentration was as follows: Hg < Co < Pb < Ni < V < Cr. Cobalt and vanadium contents were found to decrease and those of nickel, mercury, and chromium to ulerease; however, neither of these trends was observed for the lead content. One-way analyses of variance con-firm significant temporal variation only for cobalt, mercury, lead, and vanadium. Significant linear correlation coefficients (p ≤ 0.05) were found for Co-V, Cr-Ni, Cr-Pb, Co-Hg, Ni-V, and V-Pb. The first three associa-tions showed positive correlations, whereas the remaining ones had negative correlations. A factor analysis grouped the studied metals depending on their origins. The metal levels found in the muscular tissue of A. felis from the southern Gulf of México were lower than those set by national and international regulations.

Abstract: Background To improve retention on ART, Médecins Sans Frontières, the Ministry of Health and patients piloted a community-based antiretroviral distribution and adherence monitoring model through Community ART Groups (CAG) in Tete, Mozambique. By December 2012, almost 6000 patients on ART had formed groups of whom 95.7% were retained in care. We conducted a qualitative study to evaluate the relevance, dynamic and impact of the CAG model on patients, their communities and the healthcare system. Methods Between October 2011 and May 2012, we conducted 16 focus group discussions and 24 in-depth interviews with the major stakeholders involved in the CAG model. Audio-recorded data were transcribed verbatim and analysed using a grounded theory approach. Results Six key themes emerged from the data: 1) Barriers to access HIV care, 2) CAG functioning and actors involved, 3) Benefits for CAG members, 4) Impacts of CAG beyond the group members, 5) Setbacks, and 6) Acceptance and future expectations of the CAG model. The model provides cost and time savings, certainty of ART access and mutual peer support resulting in better adherence to treatment. Through the active role of patients, HIV information could be conveyed to the broader community, leading to an increased uptake of services and positive transformation of the identity of people living with HIV. Potential pitfalls included limited access to CAG for those most vulnerable to defaulting, some inequity to patients in individual ART care and a high dependency on counsellors. Conclusion The CAG model resulted in active patient involvement and empowerment, and the creation of a supportive environment improving the ART retention. It also sparked a reorientation of healthcare services towards the community and strengthened community actions. Successful implementation and scalability requires (a) the acceptance of patients as partners in health, (b) adequate resources, and (c) a well-functioning monitoring and management system.
