Association of Lutzomyia columbiana (Diptera: Psychodidae) with a Leishmaniasis Focus in Colombia Due to Species of the Leishmania mexicana Complex

In Colombia, Leishmania mexicana has a scattered geographical distribution and no sand fly vectors have been associated with its transmission. During the present study, the anthropophilic sand fly Lutzomyia columbiana was found to be the only species collected using diverse methods, in a small focus of Le. mexicana in the municipality of Samaniego, SW Colombia. Ecological data indicate that this sand fly species is present in both peri and intradomestic habitats, where it readily bites man. Further evidence comes from experimental itnfections of wild-caught Lu. columbiana with Le. mexicana after feeding on itnfected hamsters. Based on these results, it is suggested that this sand fly is the most likely vector in the study area, suggesting the existence of a previously unknown sand fly-parasite association.

Triatoma bassolsae sp. n. from Mexico with a key to species of "phyllosoma" complex

According to the descriptions of five closely related species of the genus Triatoma Laporte, 1832: T. phyllosoma (Burmeister, 1835), T. pallidipennis (Stal, 1872), T. picturata Usinger, 1939, T. longipennis Usinger, 1939 and T. mazzottii Usinger, 1941 and further published studies, these species could be included in a "specific complex" named as the species formerly described. All these species are typical from Mexico and another species was found in the same country, in the State of Puebla: Triatoma bassolsae sp. n. This species was morphologically compared with the other five of the "phyllosoma" complex, including the external male genitalia. The most important characters used to separate T. bassolsae from T. phyllosoma (which is the most similar to the other species) are the morphometric relationships on the head, with a longer anteocular region and a significant longer second rostral segment, a long and conspicuous pilosity in different areas of the body and specially on the head, and the characters of the anterolateral, lateral and discal tubercles of the pronotum, very long and sharp in the new species. The male genitalia has several differences between T. bassolsae and T. phyllosoma specially significant on the surface of the endosome process and on the branches of the phallosome support, separated at the apex in the new species. Types and paratypes are incorporated in the respective institutions in Mexico DF and Rio de Janeiro.

Human Immunodeficiency Virus Seroprevalence among Inmates of the Penitentiary Complex of the Region of Campinas, State of São Paulo, Brazil

Six hundred and ninety three male inmates from three penitentiaries, two (A and B) maximum-security systems and one (C) minimum-security facility, located in Campinas, State of São Paulo, Brazil were studied for the presence of human immunodeficiency virus (HIV) antibodies, using a cross-sectional design. The search for anti-HIV antibodies in 693 samples of sera collected was carried out by two serological tests: (a) the Microparticle enzyme immunoassay-HIV-1 and HIV-2 (MEIA) (Abbott Laboratories) and (b) the Western Blot-HIV-1 (WB) (Cambridge Biotech Corporation) to confirm positive results with MEIA. Sera reactivity for HIV antibodies was 14.4%. The highest frequency of anti-HIV antibodies was found in the A and B maximum-security prisons: 17% and 21.5%, respectively. In prison C, the frequency of reagents was 10.9%. Seventy three inmates, initially negative in the MEIA test, were checked again five and seven months later. Three of them, all from the maximum-security facilities, became reactive in the MEIA test, with confirmation in the WB, suggesting that serological conversion had occurred after imprisonment.

The status of the Lutzomyia longipalpis species complex and possible implications for Leishmania transmission

The sand fly Lutzomyia longipalpis sensu latu has been identified as the principal vector of American visceral leishmaniasis, a potentially fatal disease that primarily affects children in several countries of South and Central America. Over the past several years increases have occurred both in the number of reported cases and the population at risk: approximately 1.6 million people reside in highly endemic areas with 16,000 cases reported annually. Several studies have attempted to relate the epidemiology of this disease to variability in Lu. longipalpis that is now recognized to be a complex of at least three sibling species. Morphological variation in this species was first noted by Mangabeira (1969). Since then physiological and biochemical differences have been reported by several investigators. Recent reports in Costa Rica of the presence of Lu. longipalpis in a focus of cutaneous leishmaniasis caused by Leishmania chagasi may be an additional indication of variability in this species. While existing evidence indicates that the morphospecies Lu. longipalpis may represent a complex of sibling species, genetic, epidemiological and ecological distinctions have not been fully resolved. Thus, delimitation of systematic boundaries within the complex and corresponding to geographic distributions and roles in transmission remain unresolved. The purpose of this review is to summarize from the literature observations of polymorphism in this morphospecies and consider what significance this reported variability may have to the epidemiology of visceral leishmaniasis.

Conservation of complex knotting and slipknotting patterns in proteins.

While analyzing all available protein structures for the presence of knots and slipknots, we detected a strict conservation of complex knotting patterns within and between several protein families despite their large sequence divergence. Because protein folding pathways leading to knotted native protein structures are slower and less efficient than those leading to unknotted proteins with similar size and sequence, the strict conservation of the knotting patterns indicates an important physiological role of knots and slipknots in these proteins. Although little is known about the functional role of knots, recent studies have demonstrated a protein-stabilizing ability of knots and slipknots. Some of the conserved knotting patterns occur in proteins forming transmembrane channels where the slipknot loop seems to strap together the transmembrane helices forming the channel.

IPH response to the Joint Committee on Health and Children and members of the Northern Ireland Assembly on “Cross-border cooperation on healthcare”

The Institute of Public Health in Ireland were asked to submit a paper on 'Cross-border cooperation on healthcare' for a joint meeting between the Oireachtas Joint Committee on Health and Children and the Northern Ireland Assembly Health Committee which took place in Leinster House on 1 March 2012. Key points from the submission included: o    The Institute of Public Health in Ireland (IPH) is an all-island organisation which promotes cooperation between the Republic of Ireland and Northern Ireland with the aim of improving population health on the island and tackling health inequalities. IPH work is focused on addressing the causes of ill health rather than the design and delivery of treatment services. o    North/South cooperation on health was mandated under the Belfast Agreement in 1998 in five domains, including health promotion. IPH has supported the North South Ministerial Council (NSMC) in respect of the health promotion strand since inception. o    The Department of Health and Department of Health, Social Services and Public Safety North-South Feasibility Study (December 2011) states that mutual benefits are most evident from cooperation in the areas of (i) anticipating trends and illnesses in a collective manner (ii) public health issues (iii) specialised services where the population or activity required to sustain the service cannot be met by either jurisdiction alone and (iv) in relation to those areas adjacent to the border. o    The European Directive on Cross-Border Healthcare will be implemented in the next few years which will have implications in relation to patients travelling for healthcare across the Republic of Ireland/Northern Ireland border. o    IPH is supporting the development of new public health strategies in the Republic of Ireland and Northern Ireland which are both due for publication this year. o    There are tangible benefits from cross-border cooperation in the health sector, both in public health and in health service planning and delivery and there are many examples of successful initiatives. However, developments are not occurring in the context of an agreed plan or overall strategic context and tend to be project-based and concentrated in border counties. o    Successful cross-border cooperation requires high level support and integration into departmental policy cycles. The provision of data on an all-island basis supports cross-border cooperation as does the operation of sustainable all-island organisations which can support research, evaluations and programmes. o    In the future, cross-border cooperation in health will be more effective if developed with a strategic planning process intrinsically linked to Departmental priorities. o    North-South cooperation in the areas of alcohol, obesity, tobacco health surveys and rare diseases will be particularly beneficial.

Multi-segment foot kinematics after total ankle replacement and ankle arthrodesis during relatively long-distance gait.

This study aimed to investigate the influence of ankle osteoarthritis (AOA) treatments, i.e., ankle arthrodesis (AA) and total ankle replacement (TAR), on the kinematics of multi-segment foot and ankle complex during relatively long-distance gait. Forty-five subjects in four groups (AOA, AA, TAR, and control) were equipped with a wearable system consisting of inertial sensors installed on the tibia, calcaneus, and medial metatarsals. The subjects walked 50-m twice while the system measured the kinematic parameters of their multi-segment foot: the range of motion of joints between tibia, calcaneus, and medial metatarsals in three anatomical planes, and the peaks of angular velocity of these segments in the sagittal plane. These parameters were then compared among the four groups. It was observed that the range of motion and peak of angular velocities generally improved after TAR and were similar to the control subjects. However, unlike AOA and TAR, AA imposed impairments in the range of motion in the coronal plane for both the tibia-calcaneus and tibia-metatarsals joints. In general, the kinematic parameters showed significant correlation with established clinical scales (FFI and AOFAS), which shows their convergent validity. Based on the kinematic parameters of multi-segment foot during 50-m gait, this study showed significant improvements in foot mobility after TAR, but several significant impairments remained after AA.

Ultrastructure of the membrane attack complex of complement: detection of the tetramolecular C9-polymerizing complex C5b-8.

The ultrastructure of the membrane attack complex (MAC) of complement had been described as representing a hollow cylinder of defined dimensions that is composed of the proteins C5b, C6, C7, C8, and C9. After the characteristic cylindrical structure was identified as polymerized C9 [poly(C9)], the question arose as to the ultrastructural identity and topology of the C9-polymerizing complex C5b-8. An electron microscopic analysis of isolated MAC revealed an asymmetry of individual complexes with respect to their length. Whereas the length of one boundary (+/- SEM) was always 16 +/- 1 nm, the length of the other varied between 16 and 32 nm. In contrast, poly(C9), formed spontaneously from isolated C9, had a uniform tubule length (+/- SEM) of 16 +/- 1 nm. On examination of MAC-phospholipid vesicle complexes, an elongated structure was detected that was closely associated with the poly(C9) tubule and that extended 16-18 nm beyond the torus of the tubule and 28-30 nm above the membrane surface. The width of this structure varied depending on its two-dimensional projection in the electron microscope. By using biotinyl C5b-6 in the formation of the MAC and avidin-coated colloidal gold particles for the ultrastructural analysis, this heretofore unrecognized subunit of the MAC could be identified as the tetramolecular C5b-8 complex. Identification also was achieved by using anti-C5 Fab-coated colloidal gold particles. A similar elongated structure of 25 nm length (above the surface of the membrane) was observed on single C5b-8-vesicle complexes. It is concluded that the C5b-8 complex, which catalyzes poly(C9) formation, constitutes a structure of discrete morphology that remains as such identifiable in the fully assembled MAC, in which it is closely associated with the poly(C9) tubule.
