Barriers to sustaining antiretroviral treatment in Kisesa, Tanzania: a follow-up study to understand attrition from the antiretroviral program.
Get PDFTwo years after the introduction of free antiretroviral therapy (ART) in Tanzania and in spite of the logistical support provided to facilitate clinic attendance, a considerable level of attrition from the program was identified among clients from a semi-rural ward. Qualitative research on ART patients' health-seeking behavior identified factors affecting sustained attendance at treatment clinics. A mix of methods was used for data collection including semi-structured interviews with 42 clients and 11 service providers and 4 participatory group activities conducted with members of a post-test group between October and December 2006. A socio-ecological framework guided data analysis to categorize facilitators and barriers into individual, social, programmatic, and structural level influences, and subsequently explored their interaction and relative significance in shaping ART clients' behavior. Our findings suggest that personal motivation and self-efficacy contribute to program retention, and are affected by other individual-level experiences such as perceived health benefits or disease severity. However, these determinants are influenced by others' opinions and beliefs in the community, and constrained by programmatic and structural barriers. Individuals can develop the requisite willingness to sustain strict treatment requirements in a challenging context, but are more likely to do so within supportive family and community environments. Effectiveness and sustainability of ART roll-out could be strengthened by strategic intervention at different levels, with particular attention to community-level factors such as social networks' influence and support

Snails from Spring 1 in the Carcote saltpan, Chile, collected with the holotype by G.A. Collado. Shell measurements: (n= 5): SL: 4.52 ± 0.35 (4.20–4.90); SW: 1.98 ± 0.11 (1.90– 2.10); AL: 1.80 ± 0.20 (1.60–2.10); AW: 1.16 ± 0.15 (0.99–1.30); SW/SL: 0.44 ± 0.01 (0.43–0.45); AL/SL: 0.40 ± 0.01 (0.38–0.42); AW/AL: 0.64 ± 0.05 (0.59–0.70). Etymology. Specific name refers to the Carcote saltpan. Description. Shell elongate conic, periostracum light brown, umbilicus absent. Teleoconch with six shell whorls and fine axial striae. Aperture ovate, slightly triangular or strongly angled adapically; parietal margin of the lip slightly thickened, outer lip thin. Protoconch (Fig. 2 G) slightly differentiated from teleoconch. Operculum paucispiral, thin, ovate, grayish around a central light brown region, nucleus eccentric (Fig. 2 H–I). Radula shown in Fig. 2 J–O. Median cusps of central radular teeth elongate, distally pointed, lateral cusps five-six (n= 20, 10 teeth from voucher V 1–2, five from V 1–8, five from V 1–8), one basal cusp (n= 30, 10 teeth from each of the vouchers), basal tongue of central radular teeth V-shaped, lateral teeth with two-three cusps (n= 18, 10 teeth from voucher V 1–2, six from V 1–8, two from V 1–10) on inner and three-five cusps (n= 30, 10 teeth from voucher V 1 –2, 10 from V 1 –5, 10 from V 1–8) on outer side, central cusp larger and pointed. Inner marginal teeth having 19–22 cusps (n= 10, six from voucher V 1–2, four from V 1–8), outer marginal teeth with 29–42 cusps (n= 3, voucher V 1–2). Foot gray, propodium white, head brown-black with less pigment centrally, snout black, distal lips white. Tentacles black with a brow, central axial band and a gray horizontal band near the base (Fig. 2 P–R). Penis gray with a row of three - five apocrine glands (n= 3) along the outer edge (Fig. 2 S–U); distal portion with a terminal papilla. Distribution and habitat. Spring 1 in the Carcote saltpan (3688 m above sea level). This saltpan is a closed basin in the Chilean Altiplano. Spring 1 is a thermal water body (21 °C) that forms a rectangular pool that discharges to the central zone of the saltpan (Fig. 1). Snails were found on rocks and aquatic vegetation. Remarks. The morphology of the penis of this new species conforms to Heleobia as currently diagnosed (Hershler & Thompson 1992). The shell morphology differs from regional congeners in the form of the aperture (strongly angled adapically) and in the general ground plan of the penis [see Hubendick (1955), Collado et al. (2011 a), Collado et al. (2013) and Collado (2015) for comparisons]. Heleobia carcotensis appears to be closely related to the Heleobia snails from Colpa, Parinacota and Isluga in the Chilean Altiplano and H. opachensis from the Atacama Desert.Published as part of Collado, Gonzalo A., Valladares, Moisés A. & Méndez, Marco A., 2016, A new species of Heleobia (Caenogastropoda: Cochliopidae) from the Chilean Altiplano, pp. 277-280 in Zootaxa 4137 (2) on pages 278-279, DOI: 10.11646/zootaxa.4137.2.8, http://zenodo.org/record/26388

Aspect of joint ampullae plus diverticula varied: common lumen inflated, or collapsed, inner surface smooth or wavy, organs contorted with left ampulla to the right and vice versa, or ampullae compressed in dorso-ventral position with diverticula approached and in staggered position (Fig. 2 A,B). One mature oocyte at a time, occupying up to 3 segment lengths. Remarks. Fridericia roembkei sp. nov. belongs to a group of Fridericia species characterized by two spermathecal diverticula with a ciliated subchamber: F. perrieri (Vejdovský, 1878), F. o m e r i Stephenson, 1932, F. rendsinata Dózsa-Farkas, 1972, F. u l r i k a e Rota & Healy, 1999, F. h e a l y a e Schmelz, 2003, F. dozsae Schmelz, 2003 (Schmelz 2003: 296, 341 f.), and partly also F. galba (Hoffmeister, 1843). It differs, together with F. m a rg i na ta described below, from all species of this group in the proximal fusion of the spermathecal ampullae. Using the tabular comparison of Fridericia species with two spermathecal diverticula in Dózsa-Farkas (2009), F. roembkei sp. nov. belongs to a group of 10 species with proximally fused spermathecae. It differs from all species of this group in the absence of spermathecal ectal glands, in an exceptionally long spermathecal ectal duct, and in the ciliation of the diverticula. Differences to F. marginata sp. nov., a remarkably similar species, are dealt with in the remarks section of that species, see also Figure 5 and Table 2. The aspect of the spermathecae in F. roembkei varies considerably. The ampullae are often compressed, twisted, and in upright position, as shown in Fig. 2 A, or they are inflated into a spherical chamber—much more than shown in Fig. 2 B—mimicking the aspect in F. gamotheca (Fig. 2 F). Both aspects can be found at different times in the same living specimen. These unusual variations may be related to the thin and apparently soft ampullar walls. In the key to species of Fridericia in Schmelz (2003), F. roembkei would key out together with F. g a m o t h e c a Issel, 1905. F. gamotheca as originally described (Issel 1905) and redescribed (Rota 1995) from several Italian localities is distinguishable from F. roembkei by the more oval spermathecal diverticula, a shorter spermathecal ectal duct (1.5 x times as long as the ampulla), a larger sperm funnel, and higher segment number (40–44). Furthermore, diverticula are not ciliated (Schmelz pers. obs.) and the inflated aspect of the joint ampullae is a constant feature, not a transitory state as in F. roembkei. Some further possible differences are not straightforward because of variations noted in Rota (1995) regarding shape of diverticula, seminal vesicles and spermathecal ectal glands. Another variant of F. gamotheca from Morocco of uncertain taxonomic status (Schmelz 2003: 193 f.) has spherical diverticula, only 28–33 segments (Dózsa-Farkas 1989), and a ventral clitellum as described for F. roembkei: girdle-shaped, absent between bursal slits (Schmelz 2003). It differs from F. roembkei in a short and thick ectal duct and in the presence of spermathecal ectal glands. The morphological variability documented in the redescriptions of Dózsa-Farkas (1989) and Rota (1995) have led Collado et al. (2012) to assume that F. g a m o t h e c a is a species complex. Remarkable in F. roembkei is further the presence of both pale and yellow epidermal gland cells (Fig. 2 C,D), distinct only in living specimens, and clearly representing two different cell types. The pale cells are quasirectangular, filled with pale vesicles and mostly arranged in one row at chaetal level, while the yellow cells are smaller spots of irregular outline, not arranged in one row but nonetheless distributed with some regularity.Published as part of Schmelz, Rüdiger M. & Collado, Rut, 2013, Enchytraeidae (Oligochaeta, Annelida) from a field site in Portugal, with the description of five new species and a redescription of Enchylea heteroducta Nielsen & Christensen, 1963, pp. 307-328 in Zootaxa 3647 (2) on pages 312-314, DOI: 10.11646/zootaxa.3647.2.4, http://zenodo.org/record/21898

EH Performance of an Hybrid Energy Harvester for Autonomous Nodes
Get PDFThis paper reports the Energy Harvesting (EH) performance of a hybrid energy harvester able to collect energy form different energy sources: thermal, solar and electromagnetic. The main block of the system is the quarter-wavelength patch antenna, operating in the Industrial, Scientific and Medical (ISM) frequency band 2.4-2.5 GHz. The antenna has been designed and optimized to support a Thermo-Electric Generator (TEG) and a Solar Cell on its top. Moreover, a rectifier has been designed to work with the antenna and a DC-DC converter has been used to manage the TEG output voltage.Grant numbers : The work of A. Georgiadis, A. Collado and F.

BClass: A Bayesian Approach Based on Mixture Models for Clustering and Classification of Heterogeneous Biological Data
Get PDFBased on mixture models, we present a Bayesian method (called BClass) to classify biological entities (e.g. genes) when variables of quite heterogeneous nature are analyzed. Various statistical distributions are used to model the continuous/categorical data commonly produced by genetic experiments and large-scale genomic projects. We calculate the posterior probability of each entry to belong to each element (group) in the mixture. In this way, an original set of heterogeneous variables is transformed into a set of purely homogeneous characteristics represented by the probabilities of each entry to belong to the groups. The number of groups in the analysis is controlled dynamically by rendering the groups as 'alive' and 'dormant' depending upon the number of entities classified within them. Using standard Metropolis-Hastings and Gibbs sampling algorithms, we constructed a sampler to approximate posterior moments and grouping probabilities. Since this method does not require the definition of similarity measures, it is especially suitable for data mining and knowledge discovery in biological databases. We applied BClass to classify genes in RegulonDB, a database specialized in information about the transcriptional regulation of gene expression in the bacterium Escherichia coli. The classification obtained is consistent with current knowledge and allowed prediction of missing values for a number of genes. BClass is object-oriented and fully programmed in Lisp-Stat. The output grouping probabilities are analyzed and interpreted using graphical (dynamically linked plots) and query-based approaches. We discuss the advantages of using Lisp-Stat as a programming language as well as the problems we faced when the data volume increased exponentially due to the ever-growing number of genomic projects.
