    Full Text Available The amount of melanin pigments was investigated in 95 Peruvian alpaca, representative of six different fleece colours, by means of spectrophotometric assays: SpEM (Spectrophoto­metric Eumelanin, SpPM (Spectrophotometric Pheomelanin, SpASM (Spectrophotometric Alkali Soluble Melanin, and SpTM (Spectro­photometric Total Melanin. It was found that these melanin pigments were suitable for identifying three homogeneous groups, each consisting of two closely related colours. A low, an intermediate, and a high amount of SpASM, SpTM, and SpPM characterize pinkish grey and light reddish brown, brown and reddish brown, dark reddish brown and black fleeces, respectively. SpEM and SpTM provide a further split within this latter group; higher concentrations of these pigments distinguish black fleece from dark reddish brown.

    The distribution of tyrosine hydroxylase (TH) in the brainstem of alpaca (Lama pacos) has been analysed using immunohistochemical methods. The following catecholaminergic cell nuclei have been detected: A1, C1, A2, C2 and area postrema in the medulla oblongata; A5, A6d, A7sc and A7d in the pons; as have several mesencephalic groups: A8, A9l, A9m, A9v, A9pc, A10, A10c, A10d and A10dc. This nuclear parcellation differs from that found in rodents, but agrees with the results reported in other members of the Artiodactyla order, such as giraffe or pig, and with the catecholaminergic distribution detected in species of other mammalian orders. Thus, these findings support the hypothesis that the animals included in the same order show the same nuclear complement in the neuromodulatory systems. In addition, it seems that other species share the same catecholaminergic groups as the alpaca, suggesting that a specific nuclear disposition was important and worth maintaining throughout evolution. Moreover, the distribution of TH has been compared with that of CGRP by double immunohistochemistry. Double-labelled neurons were very isolated and observed only in a few catecholaminergic groups: A1 and C2 in the medulla oblongata, A6d, A7sc and A7d in the pons, and A9l in the mesencephalon. However, interaction between TH and CGRP may be possible in more brainstem regions, particularly the area postrema. This interaction may prove important in the regulation of the specific cardiovascular control of alpacas given their morphological characteristics. Copyright © 2010 Elsevier B.V.

    Full Text Available Abstract Tuberculosis (TB, due to infection with Mycobacterium bovis was diagnosed in a flock of alpaca in Ireland in 2004. An epidemiological investigation was conducted to identify the risk of TB for farmed alpaca where TB is endemic, the origin of the infection, the potential for alpaca-to-alpaca transmission and appropriate control measures. The investigation focused on the alpaca flock (including the farm, animal movements and breeding, feeding and flock health practice, the disease episode (including animal disease events and subsequent control measures and TB infection risk in the locality. The TB risk to alpaca is high in areas where infection is endemic in cattle and badgers and where biosecurity is inadequate. It is most likely that the source of infection for the alpaca was a local strain of M. bovis, present in cattle in this area since at least 2001. Genotyping of isolates identified a single variable number tandem repeat (VNTR profile in both cattle and alpaca in this region. Although a tuberculous badger was also removed from the vicinity, bacterial isolation was not attempted. On this farm, infection in alpaca was probably derived from a common source. Alpaca-to-alpaca transmission seems unlikely. Two broad control strategies were implemented, aimed at the rapid removal of infected (and potentially infectious animals and the implementation of measures to limit transmission. Tests that proved useful in detecting potentially-infected animals included measurement of the albumin-to-globulin ratio and regular body condition scoring. Skin testing was time consuming and unproductive, and early detection of infected animals remains a challenge. The flock was managed as a series of separate groupings, based on perceived infection risk. No further TB cases have been detected.

    Llamas and alpacas are domesticated South American camelids (SACs) important to ancestral population in the Altiplano region, and to different communities worldwide where they have been introduced. These ungulates have shown to be susceptible to several livestock viral pathogens such as members of the Pestivirus genus, in particular Bovine Viral Diarrhea (BVDV), but there is little data available on Pestivirus infections in SACs. In this study we aimed to detect and identify Pestivirus genotypes and subgroups infecting SACs in both wild and confined environments. Samples were collected from 136 llamas and 30 alpacas from different areas in the Chilean Altiplano (wild animals), and from 22 llamas and 26 alpacas diagnosed as Pestivirus positive from the Metropolitana region in Chile (confined animals). Seroneutralization tests showed titers lower than 2 in all 166 samples from Chilean Altiplano. These samples were also negative to BVDV isolation, indicating that these animals have not been exposed to Pestivirus. After reactivation of positive samples from the Metropolitana region, the 5' non-codifying region (5'NCR) and E2 glycoprotein were amplified by RT-PCR from the Pestivirus genome. Viral sequences were pairwise compared and phylogenetic trees were constructed. The 5'NCR analysis showed that all 12 sequenced isolates belonged to BVDV-1. Of particular interest, isolates from eight llama and two alpaca were BVDV-1j and two alpacas were BVDV-1b. In agreement with these results, E2 phylogenetic analysis rendered a similar grouping indicating that all 16 isolates belong to BVDV-1. However, the lower availability of E2 sequences determines the creation of a smaller number of sub-groups than the 5'NCR sequences. Based on the E2 sequences, the 5'NCR BVDV 1j group consisting of all the llamas and 3 alpacas are completely included in the E2 BVDV 1e group. Due to the universal availability of the 5'NCR segment, we propose the classification of these Chilean llamas and

    Full Text Available The identification of the genotypes of Echinococcus granulosus present in livestock and wild animals within regions endemic for cystic echinococcosis (CE is epidemiologically important. Individual strains display different biological characteristics that contribute to outbreaks of CE and that must be taken into account in the design of intervention programs. In this study, samples of hydatid cysts due to E. granulosus were collected from alpacas (4 in Puno and pigs (8 in Ayacucho in Peru, an endemic region for CE. Polymerase chain reaction amplification and DNA sequencing of specific regions of the mitochondrial cytochrome C oxidase subunit 1 and NADH dehydrogenase subunit 1 genes confirmed the presence of a strain common to sheep, the G1 genotype, in alpacas. Two different strains of E. granulosus were identified in pigs: the G1 and the G7 genotypes. This is the first report of the G1 genotype of E. granulosus in alpacas in endemic regions of CE in Peru.

    Flow cytometry has been shown to be an accurate and highly reproducible tool for the analysis of sperm function. The main objective of this study was to assess sperm function parameters in ejaculated alpaca sperm by flow cytometry. Semen samples were collected from six alpaca males and processed for flow cytometric analysis of sperm viability and plasma membrane integrity using SYBR-14⁄PI staining; acrosomal membrane integrity using FITC-conjugated Pisum Sativum Agglutinin⁄PI labelling; mitochondrial membrane potential (Δψm) by staining with JC-1 and DNA Fragmentation Index (DFI) by TUNEL. The results indicate that the mean value for sperm viability was 57 ± 8 %. Spermatozoa with intact acrosome membrane was 87.9 ± 5%, and viable sperm with intact acrosomal membrane was 46.8 ± 9%, high mitochondrial membrane potential (Δψm) was detected in 66.32 ± 9.51% of spermatozoa and mean DFI value was 0.91 ± 0.9%. The DFI was inversely correlated with high Δψm (p = 0.04; r = -0.41) and with plasma membrane integrity (p = 0.01; r = -0.47). To our knowledge, this is the first report of the assessment on the same sample of several parameters of sperm function in ejaculated alpaca sperm by flow cytometry. © 2012 Blackwell Verlag GmbH.

Since it is fundamental to characterize the camelid’s diet, the present work had as an objective the determination of the plant species selected by the alpacas (Lama pacos Linn. in different phenological stages (vegetative, reproductive and dry season. The study was carried out over three years in a paddock of 2.5 ha of sparse shrubland dominated by Acacia caven (Mol. Mol. and annual species in the herbaceous stratum, which were continually grazed by five male alpacas. The botanical composition and the forage dry matter available for grazing in the pasture was evaluated. Botanical composition of diets was estimated with the microhistological technique, using dung samples collected directly from the rectum. During the vegetative season, the most consumed plant species were annual and perennial grasses. In the reproductive season, the most important components of the diet were woody plant species, annual grasses and forbs. In the dry season, the diet was composed of a high percentage of woody plant species.La reintroducción de camélidos sudamericanos domésticos (alpaca y llamas en la zona central de Chile, hace necesario estudiar su comportamiento y adaptabilidad.

Diseño: Estudio analítico experimental. Lugar: Centro de Investigación de Bioquímica y Nutrición, Facultad de Medicina, Universidad Nacional Mayor de San Marcos. Materiales: Se utilizó los reactivos químicos p-nitrofenil fosfato sal disódica, ácido acético glacial, glicerol, ácido tricloroacético, ácido sulfúrico, molibdato de amonio, ácido ascórbico, sulfato de amonio, sephadex G-75 (45-120, sulfoetil sephadex C-50 y etilendiaminotetraacético (EDTA. Métodos: Se determinó los parámetros cinéticos Km y Vmax utilizando como sustrato el p-nitrofenil fosfato, en presencia de concentraciones variables de glicerol. Así mismo, se determinó la velocidad de liberación de los productos de la reacción en función de la concentración de dicho nucleófilo. Principales medidas de resultados: Efecto del glicerol sobre la hidrólisis del p-nitrofenil fosfato. Resultados: El glicerol en concentraciones comprendidas entre 1,16 y 3,49 M incrementó linealmente la liberación del p-nitrofenol; en cambio, la formación del fosfato inorgánico -el segundo producto liberado- no se modificó. Así mismo, los valores de Km y Vmax se incrementaron linealmente dependientes de las concentraciones de glicerol, en un rango comprendido entre 0,58 y 2,32 M. Conclusiones: Un análisis de las modificaciones que ejerce el glicerol sobre los valores de Km y Vmax y la velocidad de liberación de los productos de la reacción permite sugerir un modelo en el que la fosfatasa ácida de bajo peso molecular de hígado de alpaca cataliza la hidrólisis de fosfomonoésteres a través de un mecanismo uni biordenado, con la formación de un complejo enzima-fosfato, que sería escindido por agua o un nucleófilo, como el glicerol; en este modelo a k2 le corresponde un valor mucho mayor que k3 y k4 N.

    The 16S rRNA sequence of newly characterized haemotrophic bacteria in an opossum (Didelphis virginiana) and alpaca (Lama pacos) was determined. In addition, the 16S rRNA sequence of a haemotrophic parasite in the dog (Canis familiaris) was determined. Sequence alignment and evolutionary analysis as well as secondary structural similarity and signature nucleotide sequence motifs of their 16S rRNA genes, positioned these organisms in the genus Mycoplasma. The highest scoring sequence similarities were 16S rRNA genes from haemotrophic mycoplasma species (Haemobartonella and Eperythrozoon spp.). However, the lack of several higher-order structural idiosyncrasies used to define the pneumoniae group, suggests that these organisms and related haemotrophic mycoplasmas represent a new group of mycoplasmas. It is recommended that the organisms be named 'Candidatus Mycoplasma haemodidelphidis', 'Candidatus Mycoplasma haemolamae' and Mycoplasma haemocanis comb. nov., to provide some indication of the target cell and host species of these parasites, and to reflect their phylogenetic affiliation.

After a complete ophthalmic examination, conjunctival swabs were obtained from both eyes and cultured for aerobic and anaerobic bacteria. Logistic and Poisson regression analyses were used to evaluate the effect of age and gender on bacterial isolation. Four animals were excluded because of signs of external ocular disease. Of the remaining 46 alpacas, bacteria were recovered from 96.7% (89/92) of the eyes. A total of 190 bacterial isolates were cultured with a mean of 2.1 bacterial isolates per eye. The majority of isolates (70%) were Gram-positive. Staphylococcus xylosus (44/190: 23.2%) predominated, followed by viridans streptococci (32/190: 16.8%) and Pantoea agglomerans (24/190: 12.6%). Other frequently isolated bacteria included Rothia mucilaginosa (12/190: 6.3%), Staphylococcus equorum (12/190: 6.3%), Bacillus species (9/190: 4.7%), Moraxella ovis (9/190: 4.7%), and Moraxella catarrhalis (6/190: 3.2%). Statistical analysis showed that alpacas harboring viridans streptococci and Moraxella species were significantly younger. Gender did not significantly affect type of bacterial isolation. There appeared to be no significant effect of age or gender on number of bacteria isolated. Gram-positive aerobes were most commonly cultured, with S. xylosus and viridans streptococci predominating. To the best of the authors' knowledge, this is the first report describing the presence of Moraxella species in the healthy conjunctival sac of alpacas.

  17. Cranial arterial patterns of the alpaca (Camelidae: Vicugna pacos)

    Science.gov (United States)

    2017-01-01

    Artiodactyl cranial arterial patterns deviate significantly from the standard mammalian pattern, most notably in the possession of a structure called the carotid rete (CR)—a subdural arterial meshwork that is housed within the cavernous venous sinus, replacing the internal carotid artery (ICA). This relationship between the CR and the cavernous sinus facilitates a suite of unique physiologies, including selective brain cooling. The CR has been studied in a number of artiodactyls; however, to my knowledge, only a single study to date documents a subset of the cranial arteries of New World camelids (llamas, alpacas, vicugñas and guanacoes). This study is the first complete description of the cranial arteries of a New World camelid species, the alpaca (Vicugna pacos), and the first description of near-parturition cranial arterial morphology within New World camelids. This study finds that the carotid arterial system is conserved between developmental stages in the alpaca, and differs significantly from the pattern emphasized in other long-necked ruminant artiodactyls in that a patent, homologous ICA persists through the animal's life.

    Adenovirus-associated enteritis was diagnosed by histopathology of small intestine in a 2-year-old alpaca (Vicugna pacos). Electron microscopy confirmed intracytoplasmic and intranuclear adenoviral particles within enterocytes. Nucleic acid was extracted from paraffin-embedded tissue sections, and a pan-adenovirus nested polymerase chain reaction (PCR) assay was employed to target a partial sequence of the polymerase gene. The PCR product (321 bp) was cloned and sequenced. Comparison of the nucleotide sequence against the National Center for Biotechnology Information (NCBI) nucleotide database demonstrated 68% identity with the isolates Canine adenovirus 1 and Bovine adenovirus 3. Comparison of the predicted amino acid sequence against the NCBI database demonstrated 75% identity with Bovine adenovirus 3. Phylogenetic analysis supported the relatively close relationship of this isolate to Bovine adenovirus 3, but the alpaca isolate was sufficiently distant to be considered a potentially novel adenovirus for this species.

The filiform papillae, some with secondary papillae, were distributed on both the corpus and apex of the tongue, with stratified epithelium, and layer of keratin coat were recognized. The short (small) cone papillae had pointed top, while bunoform papillae were wide with smooth apex. The much less numerous circumvallate papillae with pseudopapillae on the each rim of the caudal lingual body were present with weak layer of keratin and intra-epithelial taste buds. The small fungiform papillae were found on the dorsal lingual surface, while the large fungiform papillae were situated on the ventral surface of the tongue, especially, in rostral part and were round in shape with numerous gustatory pores and very thin keratin coat. Pseudopapillae were present on the buccal conical 'bunoform' papillae surface, while 'elongate' buccal papillae surface was rather softly folded with thin coat of keratin. Microridges were observed in the less keratinized parts of each type of papillae. The orientation of either lingual or buccal papillae into the throat side facilitates the emptying of oral cavity from nutrient and swallowing of food. In conclusion, the anatomical features of the alpaca tongue are an adaptation to the feeding habits. © 2014 Blackwell Verlag GmbH.

    Full Text Available Alpacas (Vicugna pacos are domesticated camelids indigenous to south America and recently also bred in Europe and Italy for their high quality wool. There is little data available regarding the innervation of the male reproductive tract of this species. In the present study, the distribution of protein gene product 9.5 (PGP 9.5, neuropeptide Y (NPY, tyrosine hydroxilase (TH, calcitonin gene related peptide (CGRP and substance P (SP was analyzed in the epididymis by using immunohistochemical methods. Specimens of the caput, corpus and cauda epididymis were fixed in Bouin’s fluid and processed for immunohistochemistry analysis with primary antibodies against PGP 9.5, NPY, TH, CGRP and SP. Immunopositivity to PGP 9.5 and TH and NPY was observed in nerve fibre bundles and in single nerve fibres contained into the peritubular connective tissue. Many TH and NPY immunopositive cells were found to innervate blood vessels. Rare CGRP and SP immunopositive nerves were observed. Several PGP 9,5 and NPY immunopositive epithelial cells were observed in the caput epididymis. The results of the present study suggest a role for the innervations in modulate reproductive functions in the alpaca epididymis.

    Full Text Available During alpaca testis development and spermatogenesis, nerve growth factor (NGF may play an importantrole. The main aim of this study was to determine the expression and localization of NGF in the alpacatestis, and to discuss the important role of NGF in alpaca reproductive characteristics. Immunohistochemicalstaining technique and real-time PCR were used. The expression of NGF in the same cells one-month old(newborn alpacas 12-month, and 24-month old alpacas showed significant differences (p 0.05; NGF at different cell stages showed nosignificant differences (p > 0.05. It suggests that NGF may be involved in the regulation of spermatogenesis,which provides direct evidence for NGF action in the alpaca testis during postnatal development and spermatogenesis.

    Full Text Available Abstract Background Methanogens that populate the gastrointestinal tract of livestock ruminants contribute significantly to methane emissions from the agriculture industry. There is a great need to analyze archaeal microbiomes from a broad range of host species in order to establish causal relationships between the structure of methanogen communities and their potential for methane emission. In this report, we present an investigation of methanogenic archaeal populations in the foregut of alpacas. Results We constructed individual 16S rRNA gene clone libraries from five sampled animals and recovered a total of 947 sequences which were assigned to 51 species-level OTUs. Individuals were found to each have between 21 and 27 OTUs, of which two to six OTUs were unique. As reported in other host species, Methanobrevibacter was the dominant genus in the alpaca, representing 88.3% of clones. However, the alpaca archaeal microbiome was different from other reported host species, as clones showing species-level identity to Methanobrevibacter millerae were the most abundant. Conclusion From our analysis, we propose a model to describe the population structure of Methanobrevibacter-related methanogens in the alpaca and in previously reported host species, which may contribute in unraveling the complexity of symbiotic archaeal communities in herbivores.

    Epididymal alpaca sperm represent an alternative model for the study of alpaca semen. The objective of this study was to characterize the normal values of some functional variables in epididymal alpaca sperm using imaging flow cytometry. Alpaca testicles (n=150) were processed and sperm were recovered from the cauda epididymides. Only 76 samples with acceptable motility and sperm count were considered for assessment by imaging flow cytometry. Acrosome integrity and integrity/viability were assessed by FITC-PSA/PI and FITC-PNA/PI. Mitochondrial membrane potential (MMP) was assessed by MitoTracker CMXRos and MitoTracker Deep Red FM. Lipid peroxidation was evaluated using BODIPY 581/591 C11. Results show that the mean values for acrosome-intact sperm were 95.03±6.39% and 93.34±7.96%, using FITC-PSA and FITC-PNA, respectively. The mean values for acrosome-intact viable sperm were 60.58±12.12% with FITC-PSA/PI and 58.81±12.94% with FITC-PNA/PI. Greater MMP was detected in 65.03±15.92% and 59.52±19.19%, using MitoTracker CMXRos and MitoTracker Deep Red FM, respectively. Lipid peroxidation was 0.84±0.95%. Evaluation of acrosome-intact and acrosome-intact viable sperm with FITC-PSA/PI compared with. FITC-PNA/PI or MMP with MitoTracker CMXRos compared with MitoTracker Deep Red FM were correlated (Psperm motility (r=0.3979).

    The aim of the research was to evaluate two chemical tests for non-invasive pregnancy diagnosis from urine, the Cuboni reaction and the barium chloride test, in donkeys (Equus asinus) and alpacas (Vicugna pacos). The research was carried out from April 2013 to September 2014. Urine samples were collected on five private Czech farms from 18 jennies and 12 alpaca females. Urine was collected non-invasively into plastic cups fastened on a telescopic rod, at 6-9 week intervals. In total, 60 and 54 urine samples from alpacas and jennies, respectively, were collected. The Cuboni reaction was performed by the State Veterinary Institute Prague. The barium chloride test was done with 5 ml of urine mixed together with 5 ml of 1% barium chloride solution. Results of the Cuboni reaction were strongly influenced by the reproductive status of jennies; the test was 100% successful throughout the second half of pregnancy. However, no relationship was found between the real reproductive status of alpaca females and results of the Cuboni reaction. It was concluded that the barium chloride test is not suitable for pregnancy diagnosis either in donkeys, due to significant influence of season on the results, or in alpacas, because no relationship between results of the test and the reproductive status of alpaca females was found. In conclusion, the Cuboni reaction has potential to become a standard pregnancy diagnostic method in donkeys.

    Pasteurella multocida is a common constituent of upper respiratory tract microbiota but is frequently isolated of alpaca lung tissues from pulmonary infections. Despite its importance, very little is known about this bacteria at molecular level. In order to characterize P. multocida isolates, 24 isolates recovered from 46 mortal acute cases in young alpacas with suspected pneumonia were analyzed, using biochemical and molecular tests for capsule and LPS typing, virulence factors detection, and ERIC-PCR genetic diversity analysis. All the P. multocida isolates belonged to the capsular type A, LPS genotype L6 (related to serotypes 10, 11, 12, and 15), and possessed virulence factors gene toxA and tbpA. ERIC-PCR analysis revealed two electrophoretic profiles, and the majority of isolates (23/24) shared the same fingerprint, indicating strong evidence that there was a common source of infection for all the affect animals. This study revealed the detection of P. multocida type A, LPS genotype L6, and toxA+ and tbpA+ from dead young alpacas with pneumonia in Peru.

    This study investigated the effects of feeding a mixed grain supplement and tenderstretching (TS) alpaca carcasses on meat quality. A total of 56 castrated 24month old alpacas were divided into two treatments (pasture-only, and pasture plus supplementation). Supplemented groups were fed a mixed grain ration in addition to ad lib pasture for 10weeks. Animals were slaughtered across two kill days (n=28). One half of each carcass was suspended by the pelvis (TS) prior to chilling, and the other half was Achilles tendon hung (AH). After 24h, muscles were removed and aged for 10 and 25d. TS significantly increased sarcomere length and reduced shear force and cooking loss in the m. semimembranosus. This trend was not observed in other muscles including the m. longissimus thoracis et lumborum (LL) and m. psoas major. Ageing period resulted in a marginal improvement in LL tenderness. There is clear evidence that TS improves tenderness in the hindquarter of alpacas. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study investigated the effects of using medium voltage (~300 V) electrical stimulation (ES) and ageing on alpaca meat. A total of 50 huacaya alpacas were distributed across three age groups (18, 24 and 36 months) and two genders (females and castrated males). At 24h post mortem the m. longissimus thoracis et lumborum (LL) and m. semimembranosus (SM) muscles were removed and aged for either 5 or 10 days. In comparison to non-ES samples, ES significantly reduced: LL purge values by 3.0% and LL shear force (SF) at 5 and 10 days (by 21.6N and ageing further reduced tenderness by 6.6N), and SM SF by 5.8 N with significant age effects observed in both ES and non-ES SM samples, such that SF increased by 0.53 N with each month increase in animal age. Consumers rated ES samples higher on tenderness, juiciness, flavour and overall rating. ES and ageing of alpaca carcasses are recommended. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Carcass traits and saleable meat yield (SMY) of female and castrated male alpacas in Australia at 18, 24 and 36 months of age were investigated. Fifty huacaya alpacas, evenly distributed across 14, 20, 32 month ages and two genders, were grazed on coastal summer pastures for four months. Dressing percentage and carcass length were collected at slaughter. At 24h post-mortem the carcasses were prepared into four SMY combinations. Thirty six month animals had heavier hot carcass weights (33.7 ± 1 kg) and longer carcasses (81.2 ± 0.7 cm) as expected. The percentage of total carcass bone (17.5 ± 0.2%), fat trim (1.4 ± 0.1%) and meat trim (7.8 ± 0.4%) was assessed as a proportion of cold carcass weight. The proportion of fat increased and bone decreased with age. Females had more trim than males. SMY decreased in females and increased in males with age across all combinations suggesting that males are preferable for meat production. Copyright © 2015 Elsevier Ltd. All rights reserved.

    South American camelids have several biological, morphological and behavioural adaptations that allow them to live in geographical areas dominated by high altitudes. The liver has hematopoietic functions during the prenatal life, which could be modified in response to the unfavorable habitat. However, there are no previous data on the prenatal development of the liver in these species. In the present work, a study on the macroscopic and microscopic morphology of the liver of the alpaca during ontogeny was performed. Forty-one animals ranging in age from 20 days of embryonic development to adults were studied. Macroscopic and microscopic observations were performed on samples subjected to different techniques. Less than 7-g specimens were studied with stereoscopic magnifying glass. The general characteristics of the prenatal liver are similar to those of other mammals, and the structures related to hematopoietic function follow an ontogenic pattern similar to that of previously studied precocial species. However, there are differences in morphology when compared to descriptions for the Old World camelids, including the absence of relation between the caudate lobe and the right kidney and the lack of interlobular connective tissue. © 2015 Blackwell Verlag GmbH.

    To determine the prevalence of infection with Candidatus Mycoplasma haemolamae (Mhl), antibodies to bovine viral diarrhoea virus (BVDV), and BVDV antigen, and the prevalence of animals with elevated faecal nematode egg counts (FEC) in a sample of adult New Zealand alpaca (Vicugna pacos). Blood samples were obtained from 175 alpaca, collected from 15 farms around New Zealand, and from 31 samples sent to a diagnostic laboratory for routine haematology. Blood smears (n=170) were examined microscopically for the presence of haemoplasma, and DNA was extracted from whole blood (n=206) for real-time PCR testing for Mhl. Packed cell volume (PCV) was determined for 193 samples. Serum samples (n=195) were tested for BVDV antibody using ELISA, and for BVDV antigen using a real-time PCR assay. Faecal samples were collected from 143 animals; FEC were measured, and samples pooled for larval culture. No haemoplasma organisms were present on blood smear examination. Of the 206 blood samples, two (from the same farm) were positive for Mhl by real-time PCR testing, giving a prevalence of infection with Mhl of 0.97%. Of the 195 serum samples tested, four (2.1%) were positive for antibodies to BVDV; animals with BVDV antibodies were from 3/15 (20%) farms, none of which farmed cattle. None of the serum samples were positive by PCR for BVDV antigen. The median FEC was 50 epg (min 0, max 4,700), with 55/143 (38.5%) samples having 0 epg, and 33/143 (23.1%) having ≥250 epg. Haemonchus spp. were the most common nematodes present in faecal larval cultures from the North Island. Log 10 FEC was negatively associated with PCV (p=0.02), and was higher in males than females (pparasitism was, however, a common finding in this sample of New Zealand alpaca.

    The orexins A (oxA) and B are peptides discovered in the rat hypothalamus and successively found in some peripheral organs of the mammalian body. They binds two protein G-coupled receptors defined receptor 1 (ox1r) and 2 for orexins, the first of which is highly specific for oxA while the second binds both the peptides with equal affinity. This work aimed to detect the presence of oxA and ox1r in the testis of the South American camelid alpaca (Vicugna pacos) and investigate the role played by them on Leydig cell steroidogenesis. The species alpaca acquired, in the last years, increasing zootechnical interest for the quality of the wool produced and its breeding spread from the country of origin to USA, Australia and Europe. Immunohistochemistry allowed us to detect oxA in Leydig and Sertoli cells, spermatogonia, resting spermatocytes, round and oval spermatids. Ox1r-immunoreactivity was found in Leydig cells and round, oval and elongated spermatids. The expression of the two peptides in tissue extracts was established by using Western blotting technique. Such results demonstrated that in the alpaca testis exists in a cellular complex able to produce and/or internalize oxA. Finally, the effect of oxA on steroidogenesis was investigated by means of in vitro cultured thin testis slices which were added with oxA or/and Müllerian Inhibiting Substance (MIS), a steroidolitic agent basally produced by the Sertoli cell. OxA evoked increase of testosterone production while MIS a decrease. The consecutive addition of oxA and MIS, or vice versa, highlighted an antagonistic interplay between the two substances which has been thought to be the main molecular event at the basis of the oxA-stimulated steroidogenesis mechanism.

Prior to chilling, samples of m. longissimus thoracis et lumborum (LL) were taken to determine isocitrate dehydrogenase activity and glycogen concentration, and further meat quality samples were taken after 24h. Alpaca meat has low levels (Colour stability testing indicated alpaca meat was relatively stable during retail display with day of display having no significant effect on lightness (L*), or the 630nm/580nm ratio.

En el presente estudio la variación en el patrón de bandas G de los cromosomas de llamas y alpacas y la secuencia de dos genes mitocondriales han sido usados para estudiar el origen y la clasificación de llamas y alpacas. Patrones de bandas cromosómicas similares fueron observados en las cuatro especies de Lamini, incluso similares a los descritos para camello, Camelus bactrianus. Sin embargo, se encontraron finas y consistentes diferencias en los brazos cortos del cromosoma 1, permitiendo separar a camellos, guanacos y llamas, de las de vicuñas y alpacas. Este patrón fue consistente incluso en un híbrido guanaco x alpaca. Relaciones equivalentes fueron encontradas en las secuencias completas del gen para citocromo b, así como en el árbol de expansión mínima de las secuencias parciales de la región control, agrupando a guanacos con llamas y a vicuñas con alpacas. Los análisis filogenéticos mostraron a V. vicugna y a L. guanicoe como grupos recíprocamente monofHéticos. El análisis de las secuencias de ambos genes mostró dos ciados entre las vicuñas, concordantes con las subespecies reconocidas para esta especie, pero los resultados obtenidos para guanacos no reflejaron la existencia de las cuatro subespecies previamente propuestas. El análisis combinado de variaciones cromosómicas y moleculares demostraron una alta similitud genética entre alpacas y vicuñas, así como entre llamas y guanacos. Aunque se revela hibridización direccional, nuestros resultados apoyan fuertemente la hipótesis de que la llama se deriva de L. guanicoe, y la alpaca de V. vicugna, apoyando la reclasificación de la alpaca como V. pacosFour camelid species exist in South America: two wild, the guanaco (Lama guanicoe and

    The orexins A (OxA) and B (OxB) are two hypothalamic peptides involved in many physiological functions of the mammalian body. They act through the binding of two G-coupled receptors named receptor 1 (OX 1 ) and receptor 2 (OX 2 ) for orexins. The first receptor is specific for OxA, while the second binds both the substances with equal affinity. The orexins and the relative receptors have been traced by means of different techniques also at the periphery of the body and particularly in the adrenals, and in gastrointestinal and genital organs. Aim of this work was to investigate the presence of OxB and OX 2 by means of immunohistochemistry and Western blotting analysis in the testis of the South American camelid alpaca, a species primarily breed in Chile and Ecuador and recently diffused in Europe where the quality of its wool is particularly appreciated. OxB immunoreactivity (IR) was found in the tubular compartment of the testis where spermatogonia (resting), zygotene and pachytene spermatocytes, and spermatids clearly showed differently sized and shaped cytoplasmic positive structures. OX 2 -IR was found both in the interstitial and tubular compartments of the testis and particularly in Leydig cells and round and elongated spermatids. Western blotting analysis of testis lysates showed the presence of a protein band whose molecular weight corresponded to that currently assigned to OX 2 . Such findings easily translate the hypothesis that OxB and its receptor 2 play a functional role both in the interstitial and tubular compartments of the alpaca testis. © 2017 The Authors.

    Bovine viral diarrhoea virus (BVDV) and Neospora caninum may cause clinical disease in alpacas. Both diseases are present in the Australian cattle population. The objective of this study was to perform a serological prevalence survey for BVDV and N. caninum exposure in a regional alpaca population of South Australia. Serum samples were taken from 182 alpacas on 10 farms, which had a combined population of 1308 alpacas. Serological analysis for BVD antibodies was performed using a competitive BVDV antibody ELISA kit. Serological analysis for N. caninum was performed using an anti-Neospora ELISA with a protein G conjugate. Of the 182 alpacas sampled, 5 animals located on three properties were positive for BVDV antibodies, constituting a prevalence of 2.7% (95% confidence interval 1-6%). All samples tested negative for N. caninum antibodies. There is a low BVDV seroprevalence and N. caninum is currently either absent or present at a very low prevalence in this population of alpacas in South Australia. There is serological evidence for the presence of both organisms in South Australian beef and dairy cattle herds. Appropriate biosecurity protocols to minimise the risk of introduction and exposure should be a high priority to maintain this favourable status. © 2015 Australian Veterinary Association.

    Full Text Available Two coat phenotypes exist in Alpaca, Huacaya and Suri. The two coats show different fleece structure, textile characteristics and prices on the market. Although present scientific knowledge suggests a simple genetic model of inheritance, there is a tendency to manage and consider the two phenotypes as two different breeds. A 13 microsatellite panel was used in this study to assess genetic distance between Suri and Huacaya alpacas in a sample of non-related animals from two phenotypically pure flocks at the Illpa-Puno experimental station in Quimsachata, Peru. The animals are part of a germplasm established approximately 20 years ago and have been bred separately according to their coat type since then. Genetic variability parameters were also calculated. The data were statistically analyzed using the software Genalex 6.3, Phylip 3.69 and Fstat 2.9.3.2. The sample was tested for Hardy-Weinberg equilibrium (HWE and after strict Bonferroni correction only one locus (LCA37 showed deviation from equilibrium (Ploci associations showed significant disequilibrium. Observed heterozygosis (Ho= 0.766; SE=0.044, expected heterozygosis (He=0.769; SE=0.033, number of alleles (Na=9.667, SE=0.772 and Fixation index (F=0.004; SE=0.036 are comparable to data from previous studies. Measures of genetic distance were 0.06 for Nei’s and 0.03 for Cavalli-Sforza’s. The analysis of molecular variance reported no existing variance between populations. Considering the origin of the animals, their post domestication evolution and the reproductive practices in place, the results do not show genetic differentiation between the two populations for the studied loci.

    An ulcerative dermopathy caused by Mycobacterium ulcerans is described in two alpacas (Vicugna pacos) domiciled in endemic areas of Victoria, Australia. The diagnosis was confirmed in both cases by PCR targeting the M. ulcerans-specific insertion sequence, IS2404. Extensive wound debridement and bandaging was effective in controlling local disease in one alpaca, although the animal was eventually euthanased because of suspected disease recurrence at other anatomical sites. Treatment was not undertaken in the second animal, but the results of a complete necropsy are described. Investigation of the environs of the second animal yielded low levels of M. ulcerans DNA associated with a variety of samples. The potential use of adjunctive antibiotic therapies directed against M. ulcerans infection in this species is discussed. Mycobacterium ulcerans infection should be suspected in alpacas domiciled in endemic areas and presented with ulcerative skin disease. © 2013 The Authors.

    On 30 August CERN turned aside from its usual day-to-day preoccupations when Director-General Herwig Schopper played host to the Dalai Lama of Tibet and his entourage during the holy man's 1983 visit to Europe. In welcoming his visitor, Professor Schopper stressed the role of particle physics in helping to understand man's place in the cosmos, and how the Dalai Lama's interest would further the interrelation of science, philosophy and religion. The Dalai Lama visited the UA 1 experiment (rolled back into its 'garage' during the present fixed target operations at CERN) and the large installations for the neutrino experiments in the West Area of the SPS machine. There was an intriguing exchange of views with CERN theorists, who described how science has continually modified our view of the world around us

  14. Effect on performance of weanling alpacas following treatments against gastro-intestinal parasites.

    2013-11-15

    Nematodes and coccidia are common parasites of alpacas (Vicugna pacos), and important causes of disease in this increasingly popular livestock species. Endoparasitic infestation is thought to increase at times of natural or imposed stress, and antiparasitic treatments are often administered, although to date there is little evidence regarding their effect. Thirty-one alpaca juvenilles (cria) were divided into four groups at weaning, and received either no treatment as a control (C), fenbendazole anthelmintic (FB), toltrazuril coccidiostat (T), or both treatments (FBT). Body weights and faecal egg/oocyst counts were recorded weekly for six weeks following treatment. Although the prophylactic treatments decreased faecal egg/oocyst counts of the target organisms in the short term, there was no significant difference in egg/oocyst output over the course of the trial from animals given wormer, coccidiostat or both treatments. The group receiving anthelmintic only showed a significant reduction in live weight gain (LWG), with no significant difference in LWG between the other groups. At the conclusion of the trial, 'wormed only' alpacas weighed 3.3% less than at weaning, losing an average 1.3 kg over six weeks, whereas average LWG in the control group was 2.5 kg. Antiparasitics transiently reduced egg/oocyst output but results suggest that further investigation is required on the action of anthelmintics administered to alpaca cria at weaning and their effect on animal health and welfare.

    The aim of this study was to investigate if there was any serological evidence of Neospora caninum in alpaca populations in south-eastern Australia. Serum samples from 100 alpacas were collected from four farms. All serum samples were screened for N. caninum antibodies using a commercially available competitive ELISA. Of the 100 alpacas sampled, 3 were suspect seropositive for N. caninum. There is natural N. caninum seroprevalence in alpacas in south-eastern Australia; however, it remains undetermined whether or not this infection is currently contributing to reproductive failure in alpacas in Australia. © 2015 Australian Veterinary Association.

    To describe the clinical, gross pathologic, and histopathologic findings for a visually impaired 5.8-year-old female alpaca with multiple ocular abnormalities, as well as the clinical findings for three closely related alpacas. Four alpacas. Ophthalmic examination was performed on a 16-month-old female alpaca following observation of visual impairment while hospitalized for an unrelated illness. Following acute systemic decline and death 4.5 years later, the alpaca's brain, optic nerves, and eyes were examined grossly and histologically. Ophthalmic examination of three closely related alpacas was subsequently performed. The 16-month-old female alpaca (Alpaca 1) had ophthalmoscopic findings suggestive of a coloboma or hypoplasia of the retinal pigment epithelium (RPE) and choroid, and suspected optic nerve hypoplasia OU. Histopathology performed 4.5 years later revealed moderate to severe choroidal, RPE, and retinal hypoplasia with multifocal retinal detachments OU. However, the optic nerves were normal in size and histologic appearance when compared to an age-matched control. Clinical evaluation of the 2-year-old son of Alpaca 1 revealed iris colobomata OU and choroidal dysplasia/hypoplasia OD in addition to nonpathologic variations in melanin density including heterochromia iridis and a subalbinotic fundus OU. Clinical evaluation of the 13-year-old mother of Alpaca 1 revealed heterochromia iridis, cataracts, and a subalbinotic fundus OU. A 2-year-old half-brother of Alpaca 1 had an RPE and choroidal coloboma OS. The developmental ocular abnormalities diagnosed in these closely related alpacas are likely hereditary. © 2018 American College of Veterinary Ophthalmologists.

    South American Camelids have an increasing relevance in local economies, worldwide. These animals are bred for their meat, fur and as companion and therapy animals. Thus, their sanitary status should be well-established. According to the OIE (World Organization for Animal Health), respiratory infections mainly produced by Pasteurella spp. have been reported for camelids. It has been stated that this microorganism causes a mild disease, although many authors report it is an important cause of mortality among alpacas. Nevertheless, the incidence of infection by Pasteurella spp. in camelids still needs to be investigated. The aim of the present study was to analyze the occurrence of nasopharyngeal colonization of Lama glama by respiratory bacteria, and to assess the usefulness of serological tests for clinical diagnosis. The colonization was studied by culture techniques carried out with material taken by nasopharyngeal swabs. Bacterial isolates were first phenotypically characterized and then identified by MALDI/TOF-MS. The presence of specific serum antibodies was studied by ELISA and Western blot. In the present work Pasteurella spp. was not found. Nevertheless, we report for the first time, the colonization of L. glama by bacteria of the Acinetobacter lwoffii, at a reliable level in 19.4% of the animals. Acinetobacter species are found in different environmental sources, as well as vegetables, animals, and humans, and their role in infections has recently gained relevance. The results presented herein contribute to a better understanding of the respiratory microbiota in camelids, and increase the knowledge about environmental distribution of Acinetobacter non-baumanii species. Given that these respiratory bacteria might be the cause of infection among cattle, and even humans, this report highlights the need for further research. PMID:28303121

    Full Text Available La arquitectura y la indumentaria son disciplinas aparentemente antagónicas, pero a lo largo de la historia podemos observar como los arquitectos han escrito sobre moda, han realizado edificios al servicio de ésta o incluso han diseñado vestidos y complementos. Del mismo modo, muchos modistos y diseñadores de moda han encontrado en la arquitectura una fuente de inspiración, han heredado sus instrumentos o han colaborado con sus figuras más reconocidas para la concepción de sus diseños. La figura de Paco Rabanne constituyó un nuevo paradigma en el diseño de moda. Formado como arquitecto en l’École de Beaux Art de Paris entre 1951 y 1963, en los años 60 aplicó sus conocimientos de arquitectura en la creación de vestidos rupturistas. Influenciado por las vanguardias artísticas de la época, así como por el uso de nuevos materiales y formas en la arquitectura del momento, su obra irrumpió en el panorama de los convulsos años 60, dinamitando la tradicional concepción de la moda e introduciendo materiales y técnicas ajenas a ésta pero propios de la construcción de edificios. Su carácter innovador contribuyó para establecer un paralelismo, hasta entonces poco desarrollado, entre ambas materias.

Sexual behavior by libido in males and acceptance of female to male in the presence of a dominant follicle was evaluated, the collection of embryos simple ovulation by non-surgical technique was performed and the fresh embryos are transferred directly into the horn left. It was observed that only 40% of alpaca accept the male and female in all cases had to use two males for mating, but all llama males mounted on the first attempt and accepted all females breeding. Embryos were collected at 25 and 60% of alpacas and llamas washes respectively, all were grade 1 embryos transferable; the embryo transfer fertility evaluated by ultrasound at 25 days was 100 and 41.6% respectively for donor alpaca and llama, however ultrasound evaluation at 60 days fertility was 50 and 25% respectively for donor alpaca and llama. We conclude that there is greater reproductive seasonality in alpaca regard to llamas, all were grade 1 embryos collected, fertility evaluated by ultrasound 25 days down to 60 days, demonstrating embryonic mortality, possibly due to the non-breeding season of both species.

    We describe the performance of cell-based and antibody blood tests for the antemortem diagnosis of tuberculosis (TB) in South American camelids (SAC). The sensitivity and specificity of the gamma interferon (IFN-γ) release assay, two lateral flow rapid antibody tests (Stat-Pak and Dual Path Platform [DPP]), and two enzyme-linked immunosorbent assay (ELISA)-based antibody tests (Idexx and Enferplex) were determined using diseased alpacas from Mycobacterium bovis culture-confirmed breakdown herds and TB-free alpacas from geographical areas with no history of bovine TB, respectively. Our results show that while the sensitivities of the IFN-γ and antibody tests were similar (range of 57.7% to 66.7%), the specificity of the IFN-γ test (89.1%) was lower than those of any of the antibody tests (range of 96.4% to 97.4%). This lower specificity of the IFN-γ test was at least in part due to undisclosed Mycobacterium microti infection in the TB-free cohort, which stimulates a positive purified protein derivative (PPD) response. The sensitivity of infection detection could be increased by combining two antibody tests, but even the use of all four antibody tests failed to detect all diseased alpacas. These antibody-negative alpacas were IFN-γ positive. We found that the maximum sensitivity could be achieved only by the combination of the IFN-γ test with two antibody tests in a “test package,” although this resulted in decreased specificity. The data from this evaluation of tests with defined sensitivity and specificity provide potential options for antemortem screening of SAC for TB in herd breakdown situations and could also find application in movement testing and tracing investigations.

  8. Generation and characterization of the first immortalized alpaca cell line suitable for diagnostic and immunization studies.

    Directory of Open Access Journals (Sweden)

    Valentina Franceschi

    Full Text Available Raising of alpacas as exotic livestock for wool and meat production and as companion animals is growing in importance in the United States, Europe and Australia. Furthermore the alpaca, as well as the rest of the camelids, possesses the peculiarity of producing single-chain antibodies from which nanobodies can be generated. Nanobodies, due to their structural simplicity and reduced size, are very versatile in terms of manipulation and bio-therapeutic exploitation. In fact the biotech companies involved in nanobody production and application continue to grow in number and size. Hence, the development of reagents and tools to assist in the further growth of this new scientific and entrepreneurial reality is becoming a necessity. These are needed mainly to address alpaca disease diagnosis and prophylaxis, and to develop alpaca immunization strategies for nanobody generation. For instance an immortalized alpaca cell line would be extremely valuable. In the present work the first stabilized alpaca cell line from alpaca skin stromal cells (ASSCs was generated and characterized. This cell line was shown to be suitable for replication of viruses bovine herpesvirus-1, bovine viral diarrhea virus and caprine herpesvirus-1 and the endocellular parasite Neospora caninum. Moreover ASSCs were easy to transfect and transduce by several methods. These two latter characteristics are extremely useful when recombinant antigens need to be produced in a host homologous system. This work could be considered as a starting point for the expansion of the biotechnologies linked to alpaca farming and industry.

    Full Text Available Abstract Background Camelids are induced (reflex ovulators. We have recently documented the presence of an ovulation-inducing factor (OIF in the seminal plasma of alpacas and llamas. The objective was to test the hypothesis that OIF exerts its effect via a systemic rather than a local route and that endometrial curettage will enhance the ovulatory response to intrauterine deposition of seminal plasma in alpacas. Methods Female alpacas were assigned randomly to 6 groups (n = 15 to 17 per group in a 2 × 3 factorial design to test the effect of seminal plasma versus phosphate-buffered saline (PBS given by intramuscular injection, by intrauterine infusion, or by intrauterine infusion after endometrial curettage. Specifically, alpacas in the respective groups were given 1 2 ml of alpaca seminal plasma intramuscularly, 2 2 ml of PBS intramuscularly (negative control group, 3 2 ml of alpaca seminal plasma by intrauterine infusion, 4 2 ml of PBS by intrauterine infusion (negative control group, 5 2 ml of alpaca seminal plasma by intrauterine infusion after endometrial curettage, or 6 2 ml of PBS by intrauterine infusion after endometrial curettage (negative control group. The alpacas were examined by transrectal ultrasonography to detect ovulation and measure follicular and luteal diameters. Results Intramuscular administration of seminal plasma resulted in a higher ovulation rate than intrauterine administration of seminal plasma (93% versus 41%; P Conclusion We conclude that 1 OIF in seminal plasma effects ovulation via a systemic rather than a local route, 2 disruption of the endometrial mucosa by curettage facilitated the absorption of OIF and increased the ovulatory effect of seminal plasma, and 3 ovulation in alpacas is not associated with a physical stimulation of the genital tract, and 4 the alpaca represents an excellent biological model to evaluate the bioactivity of OIF.

    Only a few epidemiological studies on hand eczema (HE) in the metalworking industry have been conducted, and no study has attempted a long-term follow-up. In the Prospective Audi Cohort (PACO) II follow-up study, we aimed to estimate burden and prognosis of HE in a car industry setting (follow-up > 10 years). Eligible participants were individuals who had been examined in the original PACO study (1990-1998) and had been followed through until the end of their apprenticeship (n = 1909). Participants were interviewed and underwent dermatological examination. An exposure assessment was carried out according to a pre-defined algorithm. The follow-up rate was 78.3% (1494/1909). Mean follow-up time was 13.3 [standard deviation 1.3] years. The period prevalence of HE in the follow-up period was 21.0% [95% confidence interval (CI) 19.0-23.1%], yielding a cumulative incidence of 29.3% (95% CI 26.9-31.6%) in the entire study period. HE persisted after the end of apprenticeship in 40.0% (95% CI 33.3-46.7%) of subjects who had had HE during apprenticeship (n = 205). 18.0% (95% CI 15.9-20.1%) developed HE in the follow-up period (n = 1289). Around 30% of subjects were affected by HE at least once during the study period. HE persisted in 40% of the participants affected during apprenticeship.

    Hypohidrotic ectodermal dysplasia (HED), also known as anhidrotic ectodermal dysplasia, is characterized by the clinical manifestations of less sweat or no sweat, sparse or no hair, tooth agenesis and/or abnormal tooth morphology. The characteristics of alpaca ear hair differ from the back hair. The ectodysplasin A (EDA) signaling pathway has a regulatory effect on skin development and hair growth. The aim of the present study was to study the effects of EDA on alpaca hair growth by examining the mRNA and protein expression levels of EDA in alpaca ear and back skin by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively. Results indicated that EDA expression was higher in the ear skin compared with the back skin. The expression levels of let‑7b in the skin of healthy alpacas varies; the difference between let‑7b expression levels of the ear and back have been reported to be >2‑fold, suggesting a role for let‑7b in the development of adult alpaca skin and hair follicles. A dual‑luciferase reporter vector was constructed to verify the targeting relationship between microRNA let‑7b and EDA, and the results revealed that EDA was a target gene of let‑7b. Alpaca skin fibroblasts were transfected with a let‑7b eukaryotic expression vector to investigate the regulatory relationship between let‑7b and EDA. The expression of EDA was decreased in the transfected group; immunocytochemical results demonstrated that the EDA protein was abundantly expressed in the fibroblast cytoplasm. EDA protein expression was weaker in the transfected cells than in the untransfected cells. These results suggested that EDA may serve a role in alpaca hair growth and is probably a target gene of let‑7b; let‑7b downregulated EDA mRNA and protein expressions, which suggested that let‑7b may regulate alpaca hair growth. These conclusions suggested that let‑7b may be associated with HED.

    CASE DESCRIPTION A female alpaca, kept at pasture with 12 other female alpacas, 2 crias, and 5 goats, was evaluated because of clinical signs of aggression. CLINICAL FINDINGS The clinical signs of aggression progressed to include biting at other animals as well as disorientation. Three days later, the alpaca was euthanized because of suspicion of rabies virus infection. TREATMENT AND OUTCOME No physical injuries were found at necropsy. Brain tissue specimens were confirmed positive for rabies on the basis of direct fluorescent antibody test results. Molecular typing identified the rabies virus variant as one that is enzootic in raccoons. The farm was placed under quarantine, restricting movement of animals on and off the property for 6 months. To prevent further rabies cases, 14 alpacas (12 adults and 2 crias) were vaccinated by extralabel use of a large animal rabies vaccine. Of the 14 vaccinated alpacas, 8 had paired serum samples obtained immediately before and 21 days after vaccination; all 8 alpacas had adequate serum antirabies antibody production in response to rabies vaccination. As a result of an adequate serologic response, the quarantine was reduced to 3 months. In the year after the index rabies case, no other animals on the farm developed rabies. CLINICAL RELEVANCE Extralabel use of rabies vaccines in camelids was used in the face of a public health investigation. This report provides an example of handling of a rabies case for future public health investigations, which will undoubtedly need to develop ad-hoc rabies vaccination recommendations on the basis of the unique characteristics of the event.

  15. Ovarian function in South American camelids (alpacas, llamas, vicunas, guanacos).

    2011-04-01

    Ultrasound technology and hormone assays have provided a better understanding of folliculogenesis and ovulation in South American camelids in the last two decades. Females exhibit waves of ovarian follicular growth and are induced ovulators and therefore do not exhibit oestrous cycles in the manner of spontaneously ovulating species such as sheep and cattle. There is much variation in inter-wave interval among camelid species (alpaca/llama 10-22 days, vicuna 4-11 days), within species and within individual animals as the range of each phase of follicular growth is wide. Ovulation occurs 24-30h after mating and luteolysis occurs approximately 10 days later if conception fails to occur. Copyright © 2010 Elsevier B.V. All rights reserved.

    What happens when the Dalai Lama meets with leading physicists and a historian? This book is the carefully edited record of the fascinating discussions at a Mind and Life conference in which five leading physicists and a historian (David Finkelstein, George Greenstein, Piet Hut, Arthur Zajonc, Anton Zeilinger, and Tu Weiming) discussed with the Dalai Lama current thought in theoretical quantum physics, in the context of Buddhist philosophy. A contribution to the science-religion interface, and a useful explanation of our basic understanding of quantum reality, couched at a level that intelligent readers without a deep involvement in science can grasp. In the tradition of other popular books on resonances between modern quantum physics and Zen or Buddhist mystical traditions--notably The Dancing Wu Li Masters and The Tao of Physics , this book gives a clear and useful update of the genuine correspondences between these two rather disparate approaches to understanding the nature of reality.

    Full Text Available In this paper, we build upon previous work that aims at recuperating aspect oriented ideas into component based software development. In that research, a composition adapter was proposed in order to capture crosscutting concerns in the PacoSuite component based methodology. A composition adapter is visually applied onto a given component composition and the changes it describes are automatically applied. Stacking multiple composition adapters onto the same component composition can however lead to unpredictable and undesired side-effects. In this paper, we propose a solution for this issue, widely known as the feature interaction problem. We present a classification of different interaction levels among composition adapters and the algorithms required to verify them. The proposed algorithms are however of exponential nature and depend on both the composition adapters and the component composition as a whole. In order to enhance the performance of our feature interaction analysis, we present a set of theorems that define the interaction levels solely in terms of the properties of the composition adapters themselves.

    Partial pressure of arterial carbon dioxide (PaCO2) is a major regulator of cerebral blood flow (CBF). Derangements in PaCO2 have been thought to worsen clinical outcomes after many forms of cerebral injury by altering CBF. Our aim was to systematically analyze the biomedical literature to determine the effects of PaCO2 derangements on clinical outcomes after cerebral injury. We performed a search of Cochrane Library, PUBMED, CINHAL, conference proceedings, and other sources using a comprehensive strategy. Study inclusion criteria were (1) human subjects; (2) cerebral injury; (3) mechanical ventilation post-injury; (4) measurement of PaCO2; and (5) comparison of a clinical outcome measure (e.g. mortality) between different PaCO2 exposures. We performed a qualitative analysis to collate and summarize effects of PaCO2 derangements according to the recommended methodology from the Cochrane Handbook. Seventeen studies involving different etiologies of cerebral injury (six traumatic brain injury, six post-cardiac arrest syndrome, two cerebral vascular accident, three neonatal ischemic encephalopathy) met all inclusion and no exclusion criteria. Three randomized control trials were identified and only one was considered a high quality study as per the Cochrane criteria for assessing risk of bias. In 13/17 (76%) studies examining hypocapnia, and 7/10 (70%) studies examining hypercapnia, the exposed group (hypercapnia or hypocapnia) was associated with poor clinical outcome. The majority of studies in this report found exposure to hypocapnia and hypercapnia after cerebral injury to be associated with poor clinical outcome. However, the optimal PaCO2 range associated with good clinical outcome remains unclear. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to increase the knowledge on alpaca meat quality characteristics. Twenty Huacaya breed alpacas, reared under a traditional unspecialized production system at the Andean region of Peru, were slaughtered at ages between 18 and 24months. Analyses were carried out on Longissimus thoracis and lumborum muscle (LTLM), unless otherwise specified. These included composition parameters: moisture, fat, protein, ash, minerals, amino acids, fatty acid profile (of both LTLM and perirenal fat), retinol and tocopherol concentrations and myoglobin and collagen contents. Other meat quality parameters were evaluated: pH, colour, water holding capacity and Warner-Bratzler shear-force. Alpaca LTLM was characterized by a low intramuscular fat content and mineral and amino acid compositions, polyunsaturated to saturated fatty acids ratio and conjugated linoleic acid content comparable to those found for beef and sheep meat. However, specifically, alpaca meat showed a relatively high n-6 to n-3 (3.7) ratio and low vitamin E concentration. Values of alpaca meat technological quality parameters were in the ranges reported for more conventional red meats, the exception being a lower b(∗) value.

    Full Text Available Previously, our group isolated and evaluated anti-ricin single domain antibodies (sdAbs derived from llamas, engineered them to further increase their thermal stability, and utilized them for the development of sensitive immunoassays. In work focused on the development of therapeutics, Vance et al. 2013 described anti-ricin sdAbs derived from alpacas. Herein, we evaluated the utility of selected alpaca-derived anti-ricin sdAbs for detection applications, and engineered an alpaca-derived sdAb to increase its melting temperature, providing a highly thermal stable reagent for use in ricin detection. Four of the alpaca-derived anti-ricin A-chain sdAbs were produced and characterized. All four bound to epitopes that overlapped with our previously described llama sdAbs. One alpaca sdAb, F6, was found to possess both a high melting temperature (73 °C and to work optimally with a thermally stable llama anti-ricin sdAb in sandwich assays for ricin detection. We employed a combination of consensus sequence mutagenesis and the addition of a non-canonical disulfide bond to further enhance the thermal stability of F6 to 85 °C. It is advantageous to have a choice of recognition reagents when developing assays. This work resulted in defining an additional pair of highly thermal stable sdAbs for the sensitive detection of ricin.

    2015-12-01

    One of the main deficiencies affecting animal breeding programs in Peruvian alpacas is the low reproductive performance leading to low number of animals available to select from, decreasing strongly the selection intensity. Some reproductive traits could be improved by artificial selection, but very few information about genetic parameters exists for these traits in this specie. The aim of this study was to estimate genetic parameters for six reproductive traits in alpacas both in Suri (SU) and Huacaya (HU) ecotypes, as well as their genetic relationship with fiber and morphological traits. Dataset belonging to Pacomarca experimental farm collected between 2000 and 2014 was used. Number of records for age at first service (AFS), age at first calving (AFC), copulation time (CT), pregnancy diagnosis (PD), gestation length (GL), and calving interval (CI) were, respectively, 1704, 854, 19,770, 5874, 4290 and 934. Pedigree consisted of 7742 animals. Regarding reproductive traits, model of analysis included additive and residual random effects for all traits, and also permanent environmental effect for CT, PD, GL and CI traits, with color and year of recording as fixed effects for all the reproductive traits and also age at mating and sex of calf for GL trait. Estimated heritabilities, respectively for HU and SU were 0.19 and 0.09 for AFS, 0.45 and 0.59 for AFC, 0.04 and 0.05 for CT, 0.07 and 0.05 for PD, 0.12 and 0.20 for GL, and 0.14 and 0.09 for CI. Genetic correlations between them ranged from -0.96 to 0.70. No important genetic correlations were found between reproductive traits and fiber or morphological traits in HU. However, some moderate favorable genetic correlations were found between reproductive and either fiber and morphological traits in SU. According to estimated genetic correlations, some reproductive traits might be included as additional selection criteria in HU. Copyright © 2015 Elsevier B.V. All rights reserved.

  2. Spontaneous ovulation or male effect in alpacas and llamas

    2016-08-01

    Full Text Available New discoveries in ovulation induced mammals, researchers considered the question of whether spontaneous and induced ovulations are distinct entities or individual parts of a single continuum of a “malefacilitated oestrus and ovulation”. This rigid classification should be taken with precaution, because is possible that the various mechanisms involved in the spontaneous ovulation can, under specific conditions coexist in some determined species. It is possible that male hormones can provoke the ovulation by masculine pheromones. The “Ram Effect” can be used to synchronize ewes naturally, for artificial insemination. Pheromones are specialized hormones released by the ram and smelled by the ewes; they are found in the wool and wax, in such a way that synchronized the heat and the advancement of the breeding season Also, using artificial vaginal-cervical stimulation (AVS with a glass rod, ovulation has been induced in the mink, shrews and felids. This form of tactile stimulation (AVS has found no ability for induction of ovulation in SAC. Additional stimuli/cues are often necessary to facilitate the ovulatory response. They include olfactory, visual, auditory or posture, more of them very common in SAC. Few research studies in alpacas and llamas showed a variable number of females ovulating by the sole proximity of the male to the female, by adopting the copulatory position (posture (sitting or prone position, female to female mounting (tactile, males mounting females covered with aprons to avoid penis intromission (tactile and auditory, interrupted matings, sitting close to a male copulating to a female (visual, olfactory?, the guttural sound (orgling made by the copulating male (auditory, and probably other non-identified cues. The rate of spontaneous ovulation in alpacas and llamas, increase up to 50% during the breeding season. These spontaneous ovulation has been diagnosed by sexual behavior (female rejection to the male, by

    Full Text Available Four cowpox virus (CPXV outbreaks occurred in unrelated alpaca herds in Eastern Germany during 2012–2017. All incidents were initially noticed due to severe, generalized, and finally lethal CPXV infections, which were confirmed by testing of tissue and serum samples. As CPXV-infection has been described in South American camelids (SACs only three times, all four herds were investigated to gain a deeper understanding of CPXV epidemiology in alpacas. The different herds were investigated twice, and various samples (serum, swab samples, and crusts of suspicious pox lesions, feces were taken to identify additionally infected animals. Serum was used to detect CPXV-specific antibodies by performing an indirect immunofluorescence assay (iIFA; swab samples, crusts, and feces were used for detection of CPXV-specific DNA in a real-time PCR. In total, 28 out of 107 animals could be identified as affected by CPXV, by iIFA and/or PCR. Herd seroprevalence ranged from 16.1% to 81.2%. To investigate the potential source of infection, wild small mammals were trapped around all alpaca herds. In two herds, CPXV-specific antibodies were found in the local rodent population. In the third herd, CPXV could be isolated from a common vole (Microtus arvalis found drowned in a water bucket used to water the alpacas. Full genome sequencing and comparison with the genome of a CPXV from an alpaca from the same herd reveal 99.997% identity, providing further evidence that the common vole is a reservoir host and infection source of CPXV. Only in the remaining fourth herd, none of the trapped rodents were found to be CPXV-infected. Rodents, as ubiquitous reservoir hosts, in combination with increasingly popular alpacas, as susceptible species, suggest an enhanced risk of future zoonotic infections.

    Persistent hyperglycemia is common in alpacas and typically requires insulin administration for resolution; however, little is known about alpacas' response to different insulin formulations. To evaluate the effects of 3 insulin formulations on blood glucose concentrations and the use of a continuous glucose monitoring (CGM) system in alpacas. Six healthy alpacas. The CGM was installed in the left paralumbar fossa at the start of this crossover study and recorded data every 5 minutes. Regular insulin, NPH insulin, insulin glargine, and dextrose were administered to each alpaca over a 2-week period. Blood samples were collected for glucose testing at 0, 1, 2, 4, 6, 8, and 12 hours, and then every 6 hours after each administration of insulin or dextrose. Data were compared by using method comparison techniques, error grid plots, and ANOVA. Blood glucose concentrations decreased most rapidly after regular insulin administration when administered IV or SC as compared to the other formulations. The NPH insulin produced the longest suppression of blood glucose. The mean CGM interstitial compartment glucose concentrations were typically lower than the intravascular compartment glucose concentrations. The alpacas had no adverse reactions to the different insulin formulations. The NPH insulin might be more appropriate for long-term use in hyperglycemic alpacas because of its extended duration of action. A CGM is useful in monitoring glucose trends and reducing blood collection events, but it should not be the sole method for determining treatment protocols.

    Pregnancy maintenance depends on the maternal recognition of pregnancy (MRP), a physiological process by which the lifespan of the corpus luteum is prolonged. This mechanism is not well characterized in camelids. The objectives of the present research were to determine if exogenous oxytocin prolongs the corpus luteum activity in alpacas and to evaluate expression and localization of oxytocin receptors within the endometrium at 9 and 14days post-mating. In the oxytocin studies, plasma progesterone profiles were determined after ovulation in the same alpacas on 2 cycles: one cycle without oxytocin treatment and one cycle with oxytocin treatment. Oxytocin was administered daily by intramuscular injections (IM) at a dose of 20IU (experiment 1, n=6) or 60IU (experiment 2, n=7 from day 3 through day 10 after induction of ovulation with GnRH IM. There was no significant difference in the length of the luteal phase (i.e. corpus luteum lifespan) between the treated and control cycles using either 20 or 60IU of oxytocin. In the final experiment, uteri from open and pregnant alpacas (n=4 per group) at 9 and 14days post-mating were evaluated for expressions of oxytocin receptors by immunohistochemistry. No significant difference (P≤0.05) in the expression of oxytocin receptors was observed between open and pregnant animals in either staining intensity or tissue localization. We conclude that oxytocin is not involved in luteolysis and early MRP in alpacas. Published by Elsevier B.V.

    The young male alpaca ear and the back skins were used to investigate the effect of transforming growth factor receptor-β I (TGFβR I) on alpaca hair follicles and hair growth. The expression level and location of TGFβR I in alpaca ear and dorsal skin were detected through real-time quantitative PCR (RT-PCR) and paraffin section immunohistochemical technique (ICC-P). The results shown TGFβR I was lower expression in back skin compared to ear skin and the mean density of the positive reaction in ear skin was significantly higher than back skin. The targeted relationship with let-7b was detected using the dual-luciferase reporter vector of TGFβR I, which showed a significant target relationship between let-7b and TGFβR I. After transfection with let-7b eukaryotic expression vector, the relative mRNA expression of TGFβR I in alpaca skin fibroblasts did not differ, while the relative protein level was significantly decreased. In summary, a higher TGFβR I expression level in the ear skin suggests that TGFβR I may inhibit coat hair elongation. Further studies showed TGFβR I protein was downregulated by let-7b through transcriptional repression. Copyright © 2015 Elsevier B.V. All rights reserved.

    The synthesis of anti-Müllerian Hormone (AMH) by the Sertoli cells in males is crucial for sexual differentiation. There are no studies on AMH in Camelids. The objectives of this research were to 1) compare AMH serum concentrations in prepubertal and adult male alpacas and 2) determine the effect of castration on these concentrations in adult males to provide a validation of a commercial AMH test in alpacas. Serum samples were obtained from 15 prepubertal animals (5 for each age groups of 6, 7 and 8 months) and from 5 adult males (age 5-9 years), pre- and 24 h post-castration. AMH was determined with a quantitative ELISA according to the manufacture's instructions. There was not significant difference (P < 0.05) in AMH level (pg/ml) between pre-pubertal (549.9 ± 120.8, 789.4 ± 172.3, 597.5 ± 177.3 for ages 4, 7, and 8 months, respectively) and adult alpacas (938.7 ± 175.9). In adult males, AMH concentration decreased significantly following castration (P < 0.05) (938.7 ± 383.5 pg/ml) pre-castration, and 222.1 ± 116.5 pg/ml) after castration). There was a positive correlation between testosterone levels and AMH. In conclusion, the quantitative assay used is a reliable test to determine AMH in alpacas. The AMH level in prepubertal and adult alpacas appear to not differ, contrarily from other mammals, this requires further investigation. The decrease in serum AMH concentrations after castration suggests that measurement of this hormone can be used to diagnose bilateral cryptorchid or hemicastrated unilateral cryptorchid animals in this species.

    The objectives of the present study were to characterize the MC1R gene, its transcripts and the single nucleotide polymorphisms (SNPs) associated with coat color in alpaca. Full length cDNA amplification revealed the presence of two transcripts, named as F1 and F2, differing only in the length of their 5′-terminal untranslated region (UTR) sequences and presenting a color specific expression. Whereas the F1 transcript was common to white and colored (black and brown) alpaca phenotypes, the shorter F2 transcript was specific to white alpaca. Further sequencing of the MC1R gene in white and colored alpaca identified a total of twelve SNPs; among those nine (four silent mutations (c.126C>A, c.354T>C, c.618G>A, and c.933G>A); five missense mutations (c.82A>G, c.92C>T, c.259A>G, c.376A>G, and c.901C>T)) were observed in coding region and three in the 3′UTR. A 4 bp deletion (c.224 227del) was also identified in the coding region. Molecular segregation analysis uncovered that the combinatory mutations in the MC1R locus could cause eumelanin and pheomelanin synthesis in alpaca. Overall, our data refine what is known about the MC1R gene and provides additional information on its role in alpaca pigmentation. PMID:25685836

    Nowadays there is solid clinical information for combining β2-agonists and anti-muscarinic agents, although the nature (additive or synergistic) of the net clinical result obtained by co-administration of these two classes of bronchodilators is not completely elucidated from a pharmacological point of view. Recent preclinical studies demonstrated that combining a long-acting β2-agonist (LABA) with a long-acting anti-muscarinic agent (LAMA) provides synergistic benefit on airway smooth muscle relaxation, which may have major implications for the use of LABA/LAMA combinations in the treatment COPD. Indeed, the LABA/LAMA synergism has been proved also in patients with moderate-to-severe COPD. Nevertheless, there is still a strong medical need for dose-finding clinical trials designed to identify the most favourable doses of LABA/LAMA combinations able to induce a real synergism. We strongly believe that the Bliss Independence theory represents an effective model for investigating the cross-talk between β2-adrenoreceptor and the muscarinic pathways leading to the synergistic interaction between β2-agonists and anti-muscarinic agents. In any case, the possibility of eliciting a synergistic bronchodilator effect when combining a LABA and a LAMA suggests that the therapeutic approach proposed by GOLD recommendations to only use LABA/LAMA combination in more severe COPD patients who are not controlled by a single bronchodilator should be reconsidered. We support the possibility of an early intervention with low doses of LABA/LAMA combination to optimize bronchodilation and reduce the risk of adverse events that characterize both LABAs and LAMAs, especially when administered at the full doses currently approved for the treatment of COPD.

    Cytogenetic chromosome maps offer molecular tools for genome analysis and clinical cytogenetics and are of particular importance for species with difficult karyotypes, such as camelids (2n = 74). Building on the available human–camel zoo-fluorescence in situ hybridization (FISH) data, we developed the first cytogenetic map for the alpaca (Lama pacos, LPA) genome by isolating and identifying 151 alpaca bacterial artificial chromosome (BAC) clones corresponding to 44 specific genes. The genes were mapped by FISH to 31 alpaca autosomes and the sex chromosomes; 11 chromosomes had 2 markers, which were ordered by dual-color FISH. The STS gene mapped to Xpter/Ypter, demarcating the pseudoautosomal region, whereas no markers were assigned to chromosomes 14, 21, 22, 28, and 36. The chromosome-specific markers were applied in clinical cytogenetics to identify LPA20, the major histocompatibility complex (MHC)-carrying chromosome, as a part of an autosomal translocation in a sterile male llama (Lama glama, LGL; 2n = 73,XY). FISH with LPAX BACs and LPA36 paints, as well as comparative genomic hybridization, were also used to investigate the origin of the minute chromosome, an abnormally small LPA36 in infertile female alpacas. This collection of cytogenetically mapped markers represents a new tool for camelid clinical cytogenetics and has applications for the improvement of the alpaca genome map and sequence assembly.

    Adequate cerebral perfusion is of particular concern to the clinician and is a major factor in postoperative morbidity. Cerebral circulation has the ability to autoregulate blood flow in order to maintain nutrient delivery and prevent high intravascular pressures. The focus of this study was to characterize the impact of gradually changing arterial CO2 levels on cerebral perfusion. A total of eight porcine subjects were placed into either a normothermic group (NG, N = 4, rectal temperature = 35.4+/-1.2 degrees C) or a hypothermic group (HG, N = 4, 30.6+/-0.6 degrees C). After initiation of cardiopulmonary bypass, the PaCO2 values sequentially varied between 24 and 56 mmHg. Arterial, venous, and internal jugular blood gas data were collected at 4 mmHg increments, and relative cerebral blood flow was calculated as CBF = 1 (CarterialO2-CjugularO2)(-1) Physiological parameters were similar in both groups across all test conditions: mean arterial pressure-NG 81.6+/-11.9 mmHg versus HG 73.4+/-7.0 mmHg, p = NS, and systemic oxygen consumption-HG 110.6+/-30.0 mL min versus NG 136.4+/-37.9 mL min(-1), p = NS. No significant differences were found in CBF in the NG (21.8+/-4.4 mL min(-1) 100 gL at PaCO2 = 56 mmHg versus 20.5+/-5.0 mL min(-1) 100 g(-1) at PaCO2 = 24 mmHg) or the HG (24.3+/-9.5 mL min(-1) 100 g(-1) at PaCO2 = 56 mmHg versus 25.6+/-12.0 mL min(-1) 100 g(-1) at PaCO2 = 24 mmHg). In conclusion, the alteration of PaCO2 under both hypothermic and normothermic conditions resulted in no significant differences in 1 (CarterialO2 - CjugularO2)(-1) in this model.

    Full Text Available Abstract Background MicroRNAs (miRNAs are small, non-coding 21–25 nt RNA molecules that play an important role in regulating gene expression. Little is known about the expression profiles and functions of miRNAs in skin and their role in pigmentation. Alpacas have more than 22 natural coat colors, more than any other fiber producing species. To better understand the role of miRNAs in control of coat color we performed a comprehensive analysis of miRNA expression profiles in skin of white versus brown alpacas. Results Two small RNA libraries from white alpaca (WA and brown alpaca (BA skin were sequenced with the aid of Illumina sequencing technology. 272 and 267 conserved miRNAs were obtained from the WA and BA skin libraries, respectively. Of these conserved miRNAs, 35 and 13 were more abundant in WA and BA skin, respectively. The targets of these miRNAs were predicted and grouped based on Gene Ontology and KEGG pathway analysis. Many predicted target genes for these miRNAs are involved in the melanogenesis pathway controlling pigmentation. In addition to the conserved miRNAs, we also obtained 22 potentially novel miRNAs from the WA and BA skin libraries. Conclusion This study represents the first comprehensive survey of miRNAs expressed in skin of animals of different coat colors by deep sequencing analysis. We discovered a collection of miRNAs that are differentially expressed in WA and BA skin. The results suggest important potential functions of miRNAs in coat color regulation.

    Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive malignancies in the gastrointestinal tract. Emerging studies have indicated that microRNAs (miRNAs) are strongly implicated in the development and progression of ESCC. Here, we focused on the function and the underlying molecular mechanism of miR-202 in ESCC. The results showed that miR-202 was significantly down-regulated in ESCC tissues and cell lines. Overexpression of miR-202 in ECa-109 and KYSE-510 cells markedly suppressed cell proliferation and cell migration, and induced cell apoptosis. Furthermore, laminin α1 (LAMA1) expression was frequently positive in ESCC tissues and inversely correlated with miR-202 expression. Then we demonstrated that miR-202 targeted 3'-untranslated region (UTR) of LAMA1 and inhibited its protein expression. Additionally, LAMA1 overexpression rescued the proliferation inhibition and cell apoptosis elevation induced by miR-202. MiR-202 also inhibited the protein expression of p-FAK and p-Akt, which were all reversed by LAMA1 overexpression. Taken together, these findings suggest that miR-202 may function as a novel tumor suppressor in ESCC by repressing cell proliferation and migration, and its biological effects may attribute the inhibition of LAMA1-mediated FAK-PI3K-Akt signaling. - Highlights: • Expression of miR-202 was decreased in ESCC tissues and cell lines. • MiR-202 overexpression inhibited ESCC cell growth and induced apoptosis. • MiR-202 directly targeted LAMA1 in ESCC. • The LAMA1-FAK-PI3K signaling mediated the suppressive role of miR-202.

    Body and carcass composition were studied on 10 male and 10 female naturally reared llamas (Lama glama). Half the animals were young (9-12 months) and the other half adult (>3 year). The average live weights for young and adult males were 104.4 and 100.6kg, and for females 67.6 and 104.6kg, respectively. Average carcass weights for the four groups were 58.9, 56.2, 36.8 and 56.7kg, respectively. Carcass composition for males and females was similar, but males had slightly higher dressing percentages than females (56.1 and 55.8 vs. 54.1 and 54.2 for young and adult males and females, respectively). Carcass length and fat depth at the loin and proportions of cuts in the carcass were similar for both the sexes, except for leg and tail, which were proportionately heavier in young females compared to the other groups. The composition of meat on fresh basis was: moisture 70.2%, protein 20.5%, ether extract 8.23% and ash 3.4%. Age and sex seemed to have no effects on the body and carcass characteristics studied nor on the chemical composition of meat.

    Preserving cultural heritage and historic sites is an important issue. These sites are subjected to erosion and vandalism, and, as long-lived artifacts, they have gone through many phases of construction, damage and repair. It is important to keep an accurate record of these sites using the 3-D model building technology as they currently are, so that preservationists can track changes, foresee structural problems, and allow a wider audience to "virtually" see and tour these sites. Due to the complexity of these sites, building 3-D models is time consuming and difficult, usually involving much manual effort. This study discusses new methods that can reduce the time to build a model using the Unmanned Aerial Vehicle method. This study aims to develop a 3D model of a historical mosque using UAV photogrammetry. In order to achieve this, the data acquisition set of Masjid Lama Nilai, Negeri Sembilan was captured by using an Unmanned Aerial Vehicle. In addition, accuracy assessment between the actual and measured values is made. Besides that, a comparison between the rendering 3D model and texturing 3D model is also carried out through this study.

    To identify factors associated with hepatic lipidosis (HL) in llamas and alpacas. Retrospective case series. 30 llamas and 1 alpaca. Medical records were searched to identify llamas or alpacas in which a histologic diagnosis of HL was made. Information was retrieved on signalment, history, clinical and laboratory findings, and results of necropsy or examination of biopsy specimens. Data were analyzed using descriptive statistics and chi 2 analyses. Females were affected more often than males; however, the sex distribution was not different from that of the camelid population in the diagnostic laboratory's database. Fifty-four percent of the females were pregnant, and 46% were lactating. Most affected camelids were 6 to 10 years old. Anorexia and recent weight loss were common (51.6% of camelids). An infective agent was found in only one ilama, and toxins and mineral deficiencies were not identified. The most common abnormalities on serum biochemical analysis were a high concentration of bile acids, high activities of gamma-glutamyltransferase (GGT) and aspartate aminotransferase (AST), and hypoproteinemia. Concentrations of nonesterified fatty acids (NEFA) and beta-hydroxybutyrate (beta-HB) were high in those camelids in which these compounds were assayed. Twenty-nine camelids did not survive. Sick camelids should be considered at risk for developing HL, especially those with anorexia or the metabolic demands of pregnancy and lactation. Other stresses also appear to contribute. High concentrations of NEFA, beta-HB, and bile acids; high activities of GGT and AST; and hypoproteinemia may indicate that HL has developed.

    The aim of this study was to compare the anatomical and functional characteristics of the lingual papilla among the Camelidae. For this purpose, tongues of alpaca, guanaco, and llama were used. Numerous long and thin filiform papillae were located in the median groove and none were detected on the rest of the dorsal surface of the lingual apex in alpaca. Secondary papillae originated from the base of some filiform papillae on the ventral surface of alpaca tongue. The bases of some filiform papillae of the lateral surface of the lingual apex were inserted into conspicuous grooves in guanaco and tips of filiform papillae on the dorsal surface of the lingual body were ended by bifurcated apex. On the dorsal surface of the lingual apex of llama, there were no filiform papillae but there were numerous filiform papillae on both the lateral margins of the ventral surface of the lingual apex. Fungiform papillae were distributed randomly on dorsal lingual surface and ventral margins of the tongues of all camelid species. Lenticular papillae were located on the lingual torus and varied in size and topographical distribution for each species. Circumvallate papillae had irregular surfaces in llama and alpaca, and smooth surface in guanaco. In conclusion, llama and alpaca tongues were more similar to each other, and tongues of all camelid species displayed more similarities to those of Bactrian and dromedary camels in comparison with other herbivores and ruminants. © 2015 Wiley Periodicals, Inc.

    To determine indications for cesarean section in alpacas and llamas, and clinical management and outcome of alpacas and llamas undergoing cesarean section. Retrospective case series. 27 alpacas and 7 llamas. Medical records were reviewed and information gathered on signalment, anamnesis including reproductive history, physical examination findings, indication for cesarean section, anesthetic protocol, surgical technique, number of crias delivered (alive or dead), additional treatment, duration of hospitalization, and postoperative complications. Follow-up information was gathered via email or telephone interview with owners. Uterine torsion (13/34 [38%]) was the most common reason for cesarean section. The most common surgical approach was the left proximal lateral abdominal approach (21/34 [62%]). Thirty-four crias were delivered via cesarean section. Twenty (59%) were born alive and discharged from the hospital. Retained placenta was the most common complication observed after surgery. A significant association was found between prolonged dystocia and fetal death. Of the 34 dams that underwent cesarean section, 21 were rebred, and 19 of the 21 (90.5%) dams that were rebred became pregnant. Fifteen of 19 dams were confirmed to have ≥ 1 normal vaginal delivery with a live cria following cesarean section. The results of the present study indicated that cesarean section was an effective method of resolving dystocia in camelids without negatively affecting future fertility or parturition by the dam. Prompt referral of patients with dystocia is advised to improve fetal viability. Retained fetal membranes seemed to be a common complication of cesarean section in camelids but was not associated with negative outcomes.

    Rapid, economical, and quantitative assays for measurement of camelid serum immunoglobulin G (IgG) are limited. In camelids, failure of transfer of maternal immunoglobulins has a reported prevalence of up to 20.5%. An accurate method for quantifying serum IgG concentrations is required. To develop an infrared spectroscopy-based assay for measurement of alpaca serum IgG and compare its performance to the reference standard radial immunodiffusion (RID) assay. One hundred and seventy-five privately owned, healthy alpacas. Eighty-two serum samples were collected as convenience samples during routine herd visits whereas 93 samples were recruited from a separate study. Serum IgG concentrations were determined by RID assays and midinfrared spectra were collected for each sample. Fifty samples were set aside as the test set and the remaining 125 training samples were employed to build a calibration model using partial least squares (PLS) regression with Monte Carlo cross validation to determine the optimum number of PLS factors. The predictive performance of the calibration model was evaluated by the test set. Correlation coefficients for the IR-based assay were 0.93 and 0.87, respectively, for the entire data set and test set. Sensitivity in the diagnosis of failure of transfer of passive immunity (FTPI) ([IgG] <1,000 mg/dL) was 71.4% and specificity was 100% for the IR-based method (test set) as gauged relative to the RID reference method assay. This study indicated that infrared spectroscopy, in combination with chemometrics, is an effective method for measurement of IgG in alpaca serum.

    2013-02-01

    Fish pathologists are often interested in which parasites would likely be present in a particular host. Parasite Co-occurrence Modeler (PaCo) is a tool for identifying a list of parasites known from fish species that are similar ecologically, phylogenetically, and geographically to the host of interest. PaCo uses data from FishBase (maximum length, growth rate, life span, age at maturity, trophic level, phylogeny, and biogeography) to estimate compatibility between a target host and parasite species-genera from the major helminth groups (Acanthocephala, Cestoda, Monogenea, Nematoda, and Trematoda). Users can include any combination of host attributes in a model. These unique features make PaCo an innovative tool for addressing both theoretical and applied questions in parasitology. In addition to predicting the occurrence of parasites, PaCo can be used to investigate how host characteristics shape parasite communities. To test the performance of the PaCo algorithm, we created 12,400 parasite lists by applying any possible combination of model parameters (248) to 50 fish hosts. We then measured the relative importance of each parameter by assessing their frequency in the best models for each host. Host phylogeny and host geography were identified as the most important factors, with both present in 88% of the best models. Habitat (64%) was identified in more than half of the best models. Among ecological parameters, trophic level (41%) was the most relevant while life span (34%), growth rate (32%), maximum length (28%), and age at maturity (20%) were less commonly linked to best models.

    Place attachment as bonding between people-meaningful places) has been researched quite broadly. Part of this interest stems from the awareness that people–place bonds have become fragile as urbanization, increased mobility, and encroaching environmental problems threaten the existence of/and the connections to, places influences sense of attachment in Pasar Lama, Kota Tangerang. Despite its stauts as a Chinatown, the amount of Chinese inhabitant in Pasar Lama is only 1/5 compared to then total number of Native. Therefore an investigation is needed whether the advances of Kota Tangerang and increasing number of people affecting the formation of place attachment at Pasar Lama Communities. The analysis were conducted through eight factors, such as: physical, social, cultural, personal, memories and experiences, place satisfaction, interaction and activity features, and time factor. Qualitative method (ethnography approach) participatory observation and in-depth interview used as the method of research. The informant of this research are the local figure, local citizen, and local authority. Research concludes that the rapid development of Kota Tangerang and the number of citizens do not significantly affect the formation of place attachment, since both communities in Pasar Lama are considered having high attachment. The other factor is, Place Attachment is valued in contribution, a qualitative value instead sheer number of population. These contributions can be seen in the social, cultural and religious aspect based on factors on Place Attachment.

    The objectives of this study were to define disposition and systemic availability of florfenicol in alpacas. Administration of 20 mg/kg doses to 8 male alpacas by i.v., i.m. and s.c. routes was performed by randomized, 3-way crossover design. Clearance and steady state volumes (Vdss) after i.v. injection were 5 ml/min/kg and 775 ml/kg respectively. Mean residence time (MRT) and terminal phase half-life (T1/2λz) were 2.8 h and 2 h respectively. Maximum serum concentrations (Cmax) after i.m. were higher than s.c. administration (p = 0.034). After s.c. dosing, T1/2λz and MRT were greater than after i.m. injection (p florfenicol after i.m. and s.c. was not different (p > 0.05). Serum florfenicol concentrations remained >1.0 µg/ml for 20 h after i.m. dosing. Differences in rate and extent of florfenicol absorption after extravascular dosing could influence therapeutic outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2008-03-01

    To compare relative sensitivity and overall yields of various methods of fecal examination for gastrointestinal parasites in llamas and alpacas. Prospective study. Fecal samples from 42 alpacas and 62 llamas. Fecal samples were analyzed via direct smear, a modified McMaster technique with sucrose solution or saturated saline (approx 36% NaCl) solution, and a centrifugation-flotation procedure. McMaster flotation chambers were examined 15 and 60 minutes after loading. Centrifugation-flotation samples were examined after 10 and 60 minutes of flotation. The proportions of samples with positive results and concentrations of parasites were compared among methods. The centrifugation-flotation technique yielded more positive results than other methods for all parasites except small coccidia. Longer flotation time increased the proportion of positive results and parasite concentrations for all parasites except Nematodirus spp. Longer time in the McMaster chamber made little difference. By use of the modified McMaster technique, sucrose solution yielded more positive results for Trichuris spp, Eimeria macusaniensis, and strongyles, whereas saline solution yielded more positive results for Nematodirus spp and small coccidia. The saline solution McMaster test yielded more positive results for small coccidia than did most other methods, and the sucrose McMaster technique yielded more positive results for Trichuris spp. The centrifugation-flotation technique appeared to offer clear advantages in detecting infection with E macusaniensis, Trichuris spp, Nematodirus spp, and capillarids. The saline McMaster technique appeared to offer an advantage in detecting small coccidia.

    2016-08-01

    Full Text Available The South American camelids are a domesticated species adapted to the high Andes, they are considered as a species of induced ovulation. In these species, so that the release of the oocyte occurs, a neuroendocrine interaction and stimulation during intercourse (which have to lasts on average 18 minutes is necessary. In recent years, several studies have demonstrated the presence of an inducing factor for the ovulation found in the seminal plasma of the male that is crucial for ovulation to occurs in camelids. From 1968 researches were initiated to confirm and determine the inductor factor. The works have shown that ovulation in alpacas occurs after intramuscular and intravaginal application of seminal plasma. Recent studies showed the luteotropic effect of this factor, which is evidenced by the increase and retention of circulating concentrations of LH, the rapid change in the vascularization of the pre-ovulatory follicle and corpus luteum development, this contributes to the increase of the embryonic survival rate, due to the stimulus that causes this hormone in the pituitary to release LH, triggering an additional luteotropic effect on the corpus luteum with increased secretion of progesterone. At the field, level the results are not as manifest in relation to the results obtained when the ultrasound monitoring is performed. However, the work done by different research groups confirm the contribution of seminal plasma in increasing fertility rates and embryonic survival in domestic camelids such as alpaca and llama.

  16. Tracking time-varying cerebral autoregulation in response to changes in respiratory PaCO2

    2010-01-01

    Cerebral autoregulation has been studied by linear filter systems, with arterial blood pressure (ABP) as the input and cerebral blood flow velocity (CBFV—from transcranial Doppler Ultrasound) as the output. The current work extends this by using adaptive filters to investigate the dynamics of time-varying cerebral autoregulation during step-wise changes in arterial PaCO 2 . Cerebral autoregulation was transiently impaired in 11 normal adult volunteers, by switching inspiratory air to a CO 2 /air mixture (5% CO 2 , 30% O 2 and 65% N 2 ) for approximately 2 min and then back to the ambient air, causing step-wise changes in end-tidal CO 2 (EtCO 2 ). Simultaneously, ABP and CBFV were recorded continuously. Simulated data corresponding to the same protocol were also generated using an established physiological model, in order to refine the signal analysis methods. Autoregulation was quantified by the time-varying phase lead, estimated from the adaptive filter model. The adaptive filter was able to follow rapid changes in autoregulation, as was confirmed in the simulated data. In the recorded signals, there was a slow decrease in autoregulatory function following the step-wise increase in PaCO 2 (but this did not reach a steady state within approximately 2 min of recording), with a more rapid change in autoregulation on return to normocapnia. Adaptive filter modelling was thus able to demonstrate time-varying autoregulation. It was further noted that impairment and recovery of autoregulation during transient increases in EtCO 2 occur in an asymmetric manner, which should be taken into account when designing experimental protocols for the study of autoregulation

    Full Text Available Abstract Background Valuable insights into the complex process of retinal vascular development can be gained using models with abnormal retinal vasculature. Two such models are the recently described mouse lines with mutations in Lama1, an important component of the retinal internal limiting membrane (ILM. These mutants have a persistence of the fetal vasculature of vitreous (FVV but lack a primary retinal vascular plexus. The present study provides a detailed analysis of astrocyte and vascular development in these Lama1 mutants. Results Although astrocytes and blood vessels initially migrate into Lama1 mutant retinas, both traverse the peripapillary ILM into the vitreous by P3. Once in the vitreous, blood vessels anastomose with vessels of the vasa hyaloidea propria, part of the FVV, and eventually re-enter the retina where they dive to form the inner and outer retinal capillary networks. Astrocytes continue proliferating within the vitreous to form a dense mesh that resembles epiretinal membranes associated with persistent fetal vasculature and proliferative vitreoretinopathy. Conclusions Lama1 and a fully intact ILM are required for normal retinal vascular development. Mutations in Lama1 allow developing retinal vessels to enter the vitreous where they anastomose with vessels of the hyaloid system which persist and expand. Together, these vessels branch into the retina to form fairly normal inner retinal vascular capillary plexi. The Lama1 mutants described in this report are potential models for studying the human conditions persistent fetal vasculature and proliferative vitreoretinopathy.

    Merosin-deficient CMD type 1A (MDC1A), caused by mutations of laminin subunit alpha 2 (LAMA2), is a predominant subtype of congenital muscular dystrophy (CMD). Herein, we described a Chinese patient with MDC1A who was admitted to hospital 17 days after birth because of marasmus and feeding difficulties. Mutations were identified by targeted capture and next generation sequencing (NGS) and further confirmed by Sanger sequencing. Paternity was confirmed by short tandem repeat analysis. Physical examination showed malnutrition, poor suck and appendicular hypotonia. Her serum CK levels were 2483 and 1962 U/L at 2 and 4 months of age, respectively. Brain magnetic resonance imaging performed at 1 month of age presented hyperintensity on T2-weighted images, T1-weighted images in parietal and occipital lobes, and diffusion-weighted image (DWI) as well as hypointensity on fluid attenuated inversion recovery (FLAIR) image; however, the cerebellum and corpus arenaceum were normal. At 7 months of age, delayed developmental milestones were observed, and she failed to turn her body over and raise her head up. A point mutation (c.1782+2T > G) and a frameshift duplication (c.8217dupT) in the LAMA2 gene were identified by targeted capture and NGS and further confirmed by Sanger sequencing. Moreover, genotyping with multiple short tandem repeat markers confirmed paternity to demonstrate that the point mutation is de novo . The frameshift duplication (c.8217dupT), inherited from her mother, was predicted to cause a substitution of Pro (P) to Ser (S) at the 2740th amino-acid residue and generate a prematurely truncated protein. The in silico analysis suggests that the mutation (c.1782+2T > G) may lead to aberrant splicing of LAMA2. Our case further confirms the heterogeneous clinical spectrum of MDC1A and presents two novel LAMA2 mutations to expand the mutation spectrum of MDC1A.

    Merosin deficient congenital muscular dystrophy 1A (MDC1A) results from mutations in the LAMA2 gene. We report 51 patients with MDC1A and examine the relationship between degree of merosin expression, genotype and clinical features. Thirty-three patients had absence of merosin and 13 showed some residual merosin. Compared to the residual merosin group, patients with absent merosin had an earlier presentation (<7days) (P=0.0073), were more likely to lack independent ambulation (P=0.0215), or require enteral feeding (P=0.0099) and ventilatory support (P=0.0354). We identified 33 novel LAMA2 mutations; these were distributed throughout the gene in patients with absent merosin, with minor clusters in exon 27, 14, 25 and 26 (55% of mutations). Patients with residual merosin often carried at least one splice site mutation and less frequently frameshift mutations. This large study identified novel LAMA2 mutations and highlights the role of immunohistochemical studies for merosin status in predicting clinical severity of MDC1A.

  2. Abnormal Wnt and PI3Kinase signaling in the malformed intestine of lama5 deficient mice.

    Directory of Open Access Journals (Sweden)

    Léa Ritié

    Full Text Available Laminins are major constituents of basement membranes and are essential for tissue homeostasis. Laminin-511 is highly expressed in the intestine and its absence causes severe malformation of the intestine and embryonic lethality. To understand the mechanistic role of laminin-511 in tissue homeostasis, we used RNA profiling of embryonic intestinal tissue of lama5 knockout mice and identified a lama5 specific gene expression signature. By combining cell culture experiments with mediated knockdown approaches, we provide a mechanistic link between laminin α5 gene deficiency and the physiological phenotype. We show that laminin α5 plays a crucial role in both epithelial and mesenchymal cell behavior by inhibiting Wnt and activating PI3K signaling. We conclude that conflicting signals are elicited in the absence of lama5, which alter cell adhesion, migration as well as epithelial and muscle differentiation. Conversely, adhesion to laminin-511 may serve as a potent regulator of known interconnected PI3K/Akt and Wnt signaling pathways. Thus deregulated adhesion to laminin-511 may be instrumental in diseases such as human pathologies of the gut where laminin-511 is abnormally expressed as it is shown here.

    Plasma cholinesterase activity levels of various species may be of interest to toxicologists or pathologists working with chemicals that interfere with the activity of plasma cholinesterase. We used a pH titration method to measure the plasma cholinesterase activity of six mammalian species. Plasma cholinesterase activity varied up to 50-fold between species: sheep (88 ± 45 nM acetylcholine degraded per ml of test plasma per minute), cattle (94 ± 35), western grey kangaroos (126 ± 92), alpaca (364 ± 70), rats (390 ± 118) and horses (4539 ± 721). We present a simple, effective technique for the assay of plasma cholinesterase activity levels from a range of species. Although labour-intensive, it requires only basic laboratory equipment.

    Clinical signs, duration of illness, clinicopathologic findings, and ultrasonographic findings were evaluated in 12 llamas and 12 alpacas with malignant round cell tumors (MRCT). All but 1 animal died or was euthanized. Common clinical findings were anorexia, recumbency or weakness, and weight loss or poor growth. Peripheral lymphadenomegaly occurred in only 7 animals and was detected more often at necropsy than during physical examination. Common clinicopathologic abnormalities were hypoalbuminemia, acidosis, azotemia, anemia, hyperglycemia, and neutrophilia. Ultrasonography detected tumors in 4/6 animals. Cytologic evaluation of fluid or tissue aspirates or histopathology of biopsy tissue was diagnostic in 5/6 cases. A clinical course of 2 wk or less prior to death or euthanasia was more common in animals ≤ 2 y of age (9/11) than in older animals (6/13). Regular examination of camelids to include clinical pathology and evaluation of peripheral lymph nodes may result in early detection of MCRT. PMID:21358931

    A single dose of florfenicol (Nuflor(®)) was administered to eight healthy adult alpacas at 20 mg/kg intramuscular (i.m.) and 40 mg/kg subcutaneous (s.c.) using a randomized, cross-over design, and 28-day washout period. Subsequently, 40 mg/kg florfenicol was injected s.c. every other day for 10 doses to evaluate long-term effects. Maximum plasma florfenicol concentrations (C(max), measured via high-performance liquid chromatography) were achieved rapidly, leading to a higher C(max) of 4.31±3.03 μg/mL following administration of 20 mg/kg i.m. than 40 mg/kg s.c. (C(max): 1.95±0.94 μg/mL). Multiple s.c. dosing at 48 h intervals achieved a C(max) of 4.48±1.28 μg/mL at steady state. The area under the curve and terminal elimination half-lives were 51.83±11.72 μg/mL·h and 17.59±11.69 h after single 2 mg/kg i.m. dose, as well as 99.78±23.58 μg/mL·h and 99.67±59.89 h following 40 mg/kg injection of florfenicol s.c., respectively. Florfenicol decreased the following hematological parameters after repeated administration between weeks 0 and 3: total protein (6.38 vs. 5.61 g/dL, Pflorfenicol should thus be used in alpacas and limited to treatment of highly susceptible pathogens. © 2011 Blackwell Publishing Ltd.

    Full Text Available In 2007, a novel coronavirus associated with an acute respiratory disease in alpacas (Alpaca Coronavirus, ACoV was isolated. Full-length genomic sequencing of the ACoV demonstrated the genome to be consistent with other Alphacoronaviruses. A putative additional open-reading frame was identified between the nucleocapsid gene and 3'UTR. The ACoV was genetically most similar to the common human coronavirus (HCoV 229E with 92.2% nucleotide identity over the entire genome. A comparison of spike gene sequences from ACoV and from HCoV-229E isolates recovered over a span of five decades showed the ACoV to be most similar to viruses isolated in the 1960’s to early 1980’s. The true origin of the ACoV is unknown, however a common ancestor between the ACoV and HCoV-229E appears to have existed prior to the 1960’s, suggesting virus transmission, either as a zoonosis or anthroponosis, has occurred between alpacas and humans.

    The two most used methods to select camelid single-domain antibody-fragments (VHHs) are: displaying their repertoires on the surface of filamentous bacteriophages (phage display) or linking them to ribosomes (ribosome display). In this study, we compared specific VHHs isolated from two different immune libraries coming from two different alpacas by using these two selection methods. Three anti-GFAP (glial fibrillary acidic protein) VHHs were derived from an immune library obtained by ribosome display after immunization of one alpaca with purified GFAP, a protein expressed by astroglial cells. In parallel, three other anti-GFAP VHHs were derived from an immune library by phage display after immunization of another alpaca with a human brain tissue extract containing GFAP. All the VHHs were closely related and one VHH was found to be strictly identical in both studies. This highlights the selection pressure exerted by the camelid immune system to shape the paratope of an antibody against a defined antigen.

Relaxation of airway smooth muscle with inhaled bronchodilators is the cornerstone of treatment for stable COPD, with inhaled corticosteroids reserved for those with a history of exacerbations. Tiotropium has occupied center stage in COPD treatment for over 10 years and improves lung function, quality of life, exercise endurance, and reduces the risk of COPD exacerbation. Long-acting β2-agonists (LABAs improve lung function, reduce dynamic hyperinflation, increase exercise tolerance, health-related quality of life, and reduce acute exacerbation of COPD. The combination of long-acting muscarinic antagonists (LAMAs and LABAs is thought to leverage different pathways to induce bronchodilation using submaximal drug doses, increasing the benefits and minimizing receptor-specific side effects. Umeclidinium/vilanterol is the first combination of LAMA/LABA to be approved for use in stable COPD in USA and Europe. Additionally, indacaterol/glycopyrronium and aclidinium/formoterol have been approved in Europe and in numerous locations outside USA. Several other agents are in the late stages of development, most of which offer once-daily dosing. The benefits of new LAMA/LABA combinations include improved pulmonary function, dyspnea, and health-related quality of life, and in some cases, reduced exacerbations. These evolving treatments will provide new opportunities and challenges in the management of COPD. Keywords: bronchodilator, fixed-dose combination, chronic bronchitis, emphysema, COPD treatment

    Full Text Available Clinical cases of vitamin E deficiencies have been diagnosed in camelids and may indicate that these species are more sensitive to inadequate vitamin E in hay-based diets compared to other ruminant and equine species. In bovine, cholesterol has been reported to affect vitamin E concentrations. In order to evaluate vitamin E deficiencies in camelids, the effects of collection and storage of the blood samples prior to processing were necessary. Reports vary as to factors affecting vitamin E and cholesterol in blood samples, and diagnostic laboratories vary in instructions regarding sample handling. Blood was collected from healthy alpacas and processed under conditions including exposure to fluorescent light, serum and red blood cell contact, tube stopper contact, temperature, and hemolysis. Serum vitamin E and cholesterol concentrations were then measured. Statistical analyses found that the vitamin E concentrations decreased with prolonged contact with the tube stopper and with increasing hemolysis. Vitamin E concentration variations were seen with other factors but were not significant. Time prior to serum separation and individual animal variation was found to alter cholesterol concentrations within the sample, yet this finding was clinically unremarkable. No correlation was seen between vitamin E and cholesterol concentration, possibly due to lack of variation of cholesterol.

    Full Text Available A 3-day-old alpaca cria presented for progressive weakness and dyspnea since birth. Complete bloodwork, thoracic radiographs, and endoscopic examination of the nasal passages and distal trachea revealed no significant findings. Echocardiogram and contrast study revealed a single artery overriding a large ventricular septal defect (VSD. A small atrial septal defect or patent foramen ovale was also noted. Color flow Doppler and an agitated saline contrast study revealed bidirectional but primarily right to left flow through the VSD and bidirectional shunting through the atrial defect. Differential diagnosis based on echocardiographic findings included common arterial trunk, Tetralogy of Fallot, and pulmonary atresia with a VSD. Postmortem examination revealed a large common arterial trunk with a quadricuspid valve overriding a VSD. Additionally, defect in the atrial septum was determined to be a patent foramen ovale. A single pulmonary trunk arose from the common arterial trunk and bifurcated to the left and right pulmonary artery, consistent with a Collet and Edwards’ type I common arterial trunk with aortic predominance. Although uncommon, congenital cardiac defects should be considered in animals presenting with clinical signs of hypoxemia, dyspnea, or failure to thrive.

    Full Text Available The residue of human activities and batik industrial waste water surrounding the river will be able to increase the accumulation of chromium and to disrupt macrozoobenthic communities in the river. The aims of this study was to assess the impact of human activities surrounding the river to the macrozoobenthic communities and the accumulation of chromium in Cimanuk Lama River, Indramayu District, West Java. The study has been conducted from AprilMay 2015 based on three times sampling at three different sampling stations. The result of this study shows that the chromium accumulated in the waters of all station still meet the standard quality ranging from 0,010-0,016 mg/l, but only station 1 fulfills the standard quality for chromium accumulated in the river sediment with the range of all stations was about 11,72-46,63 mg/kg. The results also show that the community index analysis describes the change of macrozoobenthic community at all stations caused by environmental pressure, especially at the station 2 which is indicated by the highest score of Family Biotic Index. The accumulation of the chromium in the waters and the change of macrozoobenthic community structure are mostly influenced by the use of the Cimanuk Lama river long for agricultural and fisheries activities, and also batik home industry.

    In this article Jennifer Lewis argues that the detective novels of Paco Ignacio Taibo II adapt the conventions of the detective novel in order to examine and critique the idea of ‘Mexicanness’ in a post-colonial world.. She argues that these novels, with their unlikely (anti)hero, fantastic plots and playfully ironic style, respond in different ways to an array of different questions triggered by Mexico’s violent history: how to represent a city that is both “magical” and monstrous; how to re...

    The main objective was to study the effects, on sperm function, of the addition of two superoxide dismutase (SOD) analogues (Tempo and Tempol) to alpaca semen extender for cryopreservation. Twelve alpaca semen samples were collected using an artificial vagina and then diluted at a 1:3 ratio in an extender based on skim milk, egg yolk, and fructose. Each semen sample was divided into three equal parts to form the following groups: control, Tempo (1 mM), and Tempol (1 mM). Groups were cooled to 5 °C in 90 minutes (-1 °C in 3 minutes); when samples reached approximately 10 °C, SOD analogues were added to the respective groups. At 5 °C, ethylene glycol (final concentration, 0.1 M) was added to each group. After 30 minutes at 5 °C, samples were loaded in 0.25 mL plastic straws, placed in liquid nitrogen vapor for 15 minutes, and then plunged. Percentages of sperm motility, functional sperm membrane integrity, and viable sperm with intact acrosomes were evaluated before and after freeze-thaw using visual analysis, the hypoosmotic swelling test, and the double-stain trypan blue/giemsa technique, respectively. The Terminal deoxymucleotidyl transferase dUTP Nick End Labeling assay was performed for evaluation of sperm DNA fragmentation of frozen-thawed sperm. Sperm motility was higher (P < 0.05) in the Tempol and Tempo groups than in the control group (mean, 22.1%, 19.7%, and 11.2%, respectively), with similar results for functional sperm membrane integrity. Additionally, DNA fragmentation was lower (P < 0.05) in the Tempol group (16.7%) than in the control group (38.8%). Viable sperm with intact acrosomes were not affected by the use of SOD analogues. There was a negative correlation (r = -0.58) between DNA fragmentation of alpaca sperm and sperm motility after freeze-thawing, but DNA damage was neither related to functional membrane integrity nor viable sperm with intact acrosomes. We concluded that DNA fragmentation and loss of motility during cryopreservation of

    Full Text Available In this study, we detected new sequence variations in LAMA2 and SGCG genes in 5 ethnic populations, and analysed their effect on enhancer composition and mRNA structure. PCR amplification and DNA sequencing were performed and followed by bioinformatics analyses using ESEfinder as well as MFOLD software. We found 3 novel sequence variations in the LAMA2 (c.3174+22_23insAT and c.6085 +12delA and SGCG (c.*102A/C genes. These variations were present in 210 tested healthy controls from Tunisian, Moroccan, Algerian, Lebanese and French populations suggesting that they represent novel polymorphisms within LAMA2 and SGCG genes sequences. ESEfinder showed that the c.*102A/C substitution created a new exon splicing enhancer in the 3'UTR of SGCG genes, whereas the c.6085 +12delA deletion was situated in the base pairing region between LAMA2 mRNA and the U1snRNA spliceosomal components. The RNA structure analyses showed that both variations modulated RNA secondary structure. Our results are suggestive of correlations between mRNA folding and the recruitment of spliceosomal components mediating splicing, including SR proteins. The contribution of common sequence variations to mRNA structural and functional diversity will contribute to a better study of gene expression.

Dual bronchodilation with new long-acting muscarinic antagonist and long-acting beta-agonist (LAMA/LABA fixed dose combination inhalers were introduced over the past 2 years. In clinical trials, these inhalers significantly improved lung function (trough forced expiratory volume in 1 second, patient-reported outcomes, and quality of life measures compared with placebo, their respective monocomponents, and tiotropium. The recorded adverse events of these new inhalers were also similar to those of their monocomponents or placebo. There are concerns regarding long-term complications (weight gain, osteoporosis, cataract and increased risk of community-acquired pneumonia with the use of inhaled corticosteroids (ICS. The new LAMA/LABA inhalers could potentially reduce the use of ICS as part and parcel of maintenance therapy in COPD. Recent studies compared these LAMA/LABA inhalers with ICS/LABA combination inhalers in moderate-to-severe COPD. The results are promising and favor the LAMA/LABA inhalers, especially in the longer duration trials. Furthermore, there is a clearer picture emerging as to the subgroup of COPD patients who may be able to successfully switch from their current ICS/LABA therapy to these new LAMA/LABA inhalers.

    Infection by the larval form of Oestrus ovis (sheep bot fly) is common in many areas of Peru. This is an obligate parasite of sheep and goats, and it is the cause of oestrosis, or nasal myiasis, which can lead to severe clinical manifestations in livestock. A case of myiasis caused by O. ovis in a llama (Lama glama) in Cuzco, Peru, is reported here. This llama presented with respiratory distress and died due to bilateral hemorrhagic pneumonia. During the necropsy, six intact dipterous larvae were recovered from the nasal fossae and cranial sinuses being identified as O. ovis. This is the first report of nasal myiasis in llamas due to O. ovis in Peru.

We intend to demonstrate that the CEBB experience set in a form of social and engaged Buddhism where prospects facing on education, social welfare and the preservation and respect for human rights are elements that approach the Brazilian reality. The lived experience of CEBB also binds to work at great social risk communities, but always connected with Brazilian identities of Buddhism that mirror the altruistic action, based on generosity and contemplation. Linked to CEBB it is also, in large part, the history and development of Buddhism in Brazil that link growth statistics and expansion as a result of social work engaged and universal responsibility with human beings.

    OBJECTIVE To evaluate 2 processing methods (commercial kit vs conical tube centrifugation) for preparing platelet rich plasma (PRP) for use in llamas and alpacas. SAMPLES Blood samples (30 mL each) aseptically collected from 6 healthy llamas and 6 healthy alpacas. PROCEDURES PRP was prepared from blood samples by use of a commercial kit and by double-step conical tube centrifugation. A CBC was performed for blood and PRP samples. Platelets in PRP samples were activated by means of a freeze-thaw method with or without 23mM CaCl 2 , and concentrations of platelet-derived growth factor-BB and transforming growth factor-β 1 were measured. Values were compared between processing methods and camelid species. RESULTS Blood CBC values for llamas and alpacas were similar. The commercial kit yielded a significantly greater degree of platelet enrichment (mean increase, 8.5 fold vs 2.8 fold) and WBC enrichment (mean increase, 3.7 fold vs 1.9 fold) than did conical tube centrifugation. Llamas had a significantly greater degree of platelet enrichment than alpacas by either processing method. No difference in WBC enrichment was identified between species. Concentrations of both growth factors were significantly greater in PRP samples obtained by use of the commercial kit versus those obtained by conical tube centrifugation. CONCLUSIONS AND CLINICAL RELEVANCE For blood samples from camelids, the commercial kit yielded a PRP product with a higher platelet and WBC concentration than achieved by conical tube centrifugation. Optimal PRP platelet and WBC concentrations for various applications need to be determined for llamas and alpacas.

    Nitric oxide (NO) and {alpha}-melanocyte-stimulating hormone ({alpha}-MSH) have been correlated with the synthesis of melanin. The NO-dependent signaling of cellular response to activate the hypothalamopituitary proopiomelanocortin system, thereby enhances the hypophysial secretion of {alpha}-MSH to stimulate {alpha}-MSH-receptor responsive cells. In this study we investigated whether an NO-induced pathway can enhance the ability of the melanocyte to respond to {alpha}-MSH on melanogenesis in alpaca skin melanocytes in vitro. It is important for us to know how to enhance the coat color of alpaca. We set up three groups for experiments using the third passage number of alpaca melanocytes: the control cultures were allowed a total of 5 days growth; the UV group cultures like the control group but the melanocytes were then irradiated everyday (once) with 312 mJ/cm{sup 2} of UVB; the UV + L-NAME group is the same as group UV but has the addition of 300 {mu}M L-NAME (every 6 h). To determine the inhibited effect of NO produce, NO produces were measured. To determine the effect of the NO to the key protein and gene of {alpha}-MSH pathway on melanogenesis, the key gene and protein of the {alpha}-MSH pathway were measured by quantitative real-time PCR and Western immunoblotting. The results provide exciting new evidence that NO can enhance {alpha}-MSH pathway in alpaca skin melanocytes by elevated MC1R. And we suggest that the NO pathway may more rapidly cause the synthesis of melanin in alpaca skin under UV, which at that time elevates the expression of MC1R and stimulates the keratinocytes to secrete {alpha}-MSH to enhance the {alpha}-MSH pathway on melanogenesis. This process will be of considerable interest in future studies.

    Full Text Available Background: Malnutrition often occurs in a critical patient caused by various things such as decreasing function of gastrointestinal tract, high process of catabolism and homeostatie destruction. Other problem that may occur when nutrition is given with high total calories could be dangerous because it could cause hiperglikemia, the production improvement of CO blood and worsen the homeostasis destruction. Objective: To find out the difference of PaCO blood in critical patients who obtain commercial enteral food diet or combined enteral food diet. Methods: This was an experimental study using randomized controlled trial with pretest-posttest control group design. The subjects were critical patients who were given care in the intensive installation Dr. Sardjito hospital Yogyakarta who met the criteria: adult patient, using ventilator and receiving enteral food diet. Results: There was no difference between PaCO blood in critical patient who obtained commercial enteral diet and com- bined enteral food diet. There was a change difference of PaCO with 55% compared with <55% from energy total (p=0.03. Conclusion: The improvement of PaCO was not caused by the type of enteral formula given, cause of the high intake of energy and carbohydrate.

    To estimate the quantitative reactivity of cerebral blood flow (CBF), the effects of sodium bicarbonate on the end-tidal CO 2 , arterial partial pressure of CO 2 (PaCO 2 ), HCO 3 - , pH and CBF were examined. The CBF was measured by 133 Xe inhalation method with ring type SPECT (HEADTOME). Activation study with sodium bicarbonate administration was performed after 30 minutes of resting study, and the reactivity of each parameters was investigated. The arterial HCO 3 - and pH increased with similar reactivity, but PaCO 2 , end-tidal CO 2 and CBF in the non-injured hemisphere changed with irregular reactivity. The excellent correlation between PaCO 2 and end-tidal CO 2 was vanished by the administration of sodium bicarbonate. The reactivity of CBF did not correlate with reactivity of PaCO 2 and end-tidal CO 2 , but correlated with arterial HCO 3 - and pH. Thus the measurement of arterial HCO 3 - and pH may be indispensable to estimate the CBF reactivity with the administration of sodium bicarbonate. (author)

    Full Text Available The objective of this study was to develop and compare the performance of laboratory grade and portable attenuated total reflectance infrared (ATR-IR spectroscopic approaches in combination with partial least squares regression (PLSR for the rapid quantification of alpaca serum IgG concentration, and the identification of low IgG (<1000 mg/dL, which is consistent with the diagnosis of failure of transfer of passive immunity (FTPI in neonates. Serum samples (n = 175 collected from privately owned, healthy alpacas were tested by the reference method of radial immunodiffusion (RID assay, and laboratory grade and portable ATR-IR spectrometers. Various pre-processing strategies were applied to the ATR-IR spectra that were linked to corresponding RID-IgG concentrations, and then randomly split into two sets: calibration (training and test sets. PLSR was applied to the calibration set and calibration models were developed, and the test set was used to assess the accuracy of the analytical method. For the test set, the Pearson correlation coefficients between the IgG measured by RID and predicted by both laboratory grade and portable ATR-IR spectrometers was 0.91. The average differences between reference serum IgG concentrations and the two IR-based methods were 120.5 mg/dL and 71 mg/dL for the laboratory and portable ATR-IR-based assays, respectively. Adopting an IgG concentration <1000 mg/dL as the cut-point for FTPI cases, the sensitivity, specificity, and accuracy for identifying serum samples below this cut point by laboratory ATR-IR assay were 86, 100 and 98%, respectively (within the entire data set. Corresponding values for the portable ATR-IR assay were 95, 99 and 99%, respectively. These results suggest that the two different ATR-IR assays performed similarly for rapid qualitative evaluation of alpaca serum IgG and for diagnosis of IgG <1000 mg/dL, the portable ATR-IR spectrometer performed slightly better, and provides more flexibility for

    Measurement of 133 Xe clearance and effluent cerebral venous blood sampling were used in 38 patients to determine the effects of cardiopulmonary bypass, and of maintaining temperature corrected or noncorrected PaCO 2 at 40 mm Hg on regulation of cerebral blood flow (CBF) and flow/metabolism coupling. After induction of anesthesia with diazepam and fentanyl, mean CBF was 25 ml X 100 g-1 X min-1 and cerebral oxygen consumption, 1.67 ml X 100 g-1 X min-1. Cerebral oxygen consumption during nonpulsatile cardiopulmonary bypass at 26 degrees C was reduced to 0.42 ml X 100 g-1 X min-1 in both groups. CBF was reduced to 14-15 ml X 100 g-1 X min-1 in the non-temperature-corrected group (n = 21), was independent of cerebral perfusion pressure over the range of 20-100 mm Hg, but correlated with cerebral oxygen consumption. In the temperature-corrected group (n = 17), CBF varied from 22 to 32 ml X 100 g-1 X min-1, and flow/metabolism coupling was not maintained (i.e., CBF and cerebral oxygen consumption varied independently). However, variation in CBF correlated significantly with cerebral perfusion pressure over the pressure range of 15-95 mm Hg. This study demonstrates a profound reduction in cerebral oxygen consumption during hypothermic nonpulsatile cardiopulmonary bypass. When a non-temperature-corrected PaCO 2 of approximately 40 mm Hg was maintained, CBF was lower, and analysis of pooled data suggested that CBF regulation was better preserved, i.e., CBF was independent of pressure changes and dependent upon cerebral oxygen consumption

    A radioimmunoassay for llama and alpaca LH was developed using a human I{sup 125}LH tracer from a commercial kit, equine LH diluted in human LH free serum as standard, and amonoclonal antibody (518B7) specific for LH but with low species specificity. A 60-min delay in the addition of the tracer and overnight incubation gave a sensitivity of 0.8 {mu}3g L{sup -1}. The intra-assay coefficient of variation was 37% at 1 {mu}g L{sup -1}, declined to 15% at 4 {mu}g L{sup -1} and was below 6% for concentrations up to 32 {mu}g L{sup -1}. The inter-assay coefficients of variation for 3 control samples were 20% (2.8 {mu}g L{sup -1}), 16% (7.1 {mu}g L{sup -1}) and 9.8% (19 {mu}g L{sup -1}). In an attempt to increase sensitivity, all tubes were preincubated for 4 h at room temperature before adding the tracer, and the sample volume was increased from 50 {mu}L to 100 {mu}L (in the standard curve the increased volume was compensated for by human LH free serum). With this protocol, the assay sensitivity was 0,5 {mu}g L{sup -1}. The assay was validated clinically and demonstrated increased concentrations of LH after mating in llamas and alpacas. Furthermore, the assay was used to monitor LH responses to a single dose of GnRH in llamas (adult males and females at different ages). (au) 9 refs.

    Llamas belong to the Camelidae family along with camels. While dromedary camel milk has been broadly characterized, data on llama milk proteins are scarce. The objective of this study was thus to investigate the protein composition of llama milk. Skimmed llama milk proteins were first characterized by a 2D separation technique coupling RP-HPLC in the first dimension with SDS-PAGE in the second dimension (RP-HPLC/SDS-PAGE). Llama milk proteins, namely caseins (αs1 -, αs2 -, β-, and κ-caseins), α-lactalbumin, lactoferrin, and serum albumin, were identified using PMF. Llama milk proteins were also characterized by online LC-ESI-MS analysis. This approach allowed attributing precise molecular masses for most of the previously MS-identified llama milk proteins. Interestingly, α-lactalbumin exhibits distinct chromatographic behaviors between llama and dromedary camel milk. De novo sequencing of the llama α-lactalbumin protein by LC coupled with MS/MS (LC-MS/MS) showed the occurrence of two amino acid substitutions (R62L/I and K89L/I) that partly explained the higher hydrophobicity of llama α-lactalbumin compared with its dromedary counterpart. Taken together, these results provide for the first time a thorough description of the protein fraction of Lama glama milk. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available In order to identify differences in functional activity, we compared the reactivity of glioma vasculature and the native cerebral vasculature to both dilate and constrict in response to altered PaCO2. Gliomas were generated by unilateral implantation of U87MGdEGFR human glioma tumor cells into the striatum of adult female athymic rats. Relative changes in total and microvascular cerebral blood volume were determined by steady state contrast agent-enhanced magnetic resonance imaging for transitions from normocarbia to hypercarbia and hypocarbia. Although hypercarbia induced a significant increase in both total and microvascular blood volume in normal brain and glioma, reactivity of glioma vasculature was significantly blunted in comparison to normal striatum; glioma total CBV increased by 0.6±0.1%/mm Hg CO2 whereas normal striatum increased by 1.5±0.2%/mm Hg CO2, (P < .0001, group t-test. Reactivity of microvascular blood volume was also significantly blunted. In contrast, hypocarbia decreased both total and microvascular blood volumes more in glioma than in normal striatum. These results indicate that cerebral blood vessels derived by tumor-directed angiogenesis do retain reactivity to CO2. Furthermore, reduced reactivity of tumor vessels to a single physiological perturbation, such as hypercarbia, should not be construed as a generalized reduction of functional activity of the tumor vascular bed.

    Microcystin-LR (MC-LR) is a type of biotoxin that pollutes the ecological environment and food. The study aimed to obtain new nanobodies from phage nanobody library for determination of MC-LR. The toxin was conjugated to keyhole limpet haemocyanin (KLH) and bovine serum albumin (BSA), respectively, then the conjugates were used as coated antigens for enrichment (coated MC-LR-KLH) and screening (coated MC-LR-BSA) of MC-LR phage nanobodies from an alpaca phage display nanobody library. The antigen-specific phage particles were enriched effectively with four rounds of biopanning. At the last round of enrichment, total 20 positive monoclonal phage nanobodies were obtained from the library, which were analyzed after monoclonal phage enzyme linked immunosorbent assay (ELISA), colony PCR and DNA sequencing. The most three positive nanobody genes, ANAb12, ANAb9 and ANAb7 were cloned into pET26b vector, then the nanobodies were expressed in Escherichia coli BL21 respectively. After being purified, the molecular weight (M.W.) of all nanobodies were approximate 15kDa with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The purified nanobodies, ANAb12, ANAb9 and ANAb7 were used to establish the indirect competitive ELISA (IC-ELISA) for MC-LR, and their half-maximum inhibition concentrations (IC 50 ) were 0.87, 1.17 and 1.47μg/L, their detection limits (IC 10 ) were 0.06, 0.08 and 0.12μg/L, respectively. All of them showed strong cross-reactivity (CRs) of 82.7-116.9% for MC-RR, MC-YR and MC-WR, and weak CRs of less than 4.56% for MC-LW, less than 0.1% for MC-LY and MC-LF. It was found that all the IC-ELISAs for MC-LR spiked in tap water samples detection were with good accuracy, stability and repeatability, their recoveries were 84.0-106.5%, coefficient of variations (CVs) were 3.4-10.6%. These results showed that IC-ELISA based on the nanobodies from the alpaca phage display antibody library were promising for high sensitive determination of multiple

    The ability to exercise is an important clinical outcome in COPD, and the improvement in exercise capacity is recognized to be an important goal in the management of COPD. Therefore, since the current interest in the use of bronchodilators in COPD is gradually shifting towards the dual bronchodilation, we carried out a meta-analysis to evaluate the impact of LABA/LAMA combination on exercise capacity and lung hyperinflation in COPD. RCTs were identified after a search in different databases of published and unpublished trials. The aim of this study was to assess the influence of LABA/LAMA combinations on endurance time (ET) and inspiratory capacity (IC), vs. monocomponents. Eight RCTs including 1632 COPD patients were meta-analysed. LABA/LAMA combinations were significantly (P meta-analysis. This meta-analysis clearly demonstrates that if the goal of the therapy is to enhance exercise capacity in patients with COPD, LABA/LAMA combinations consistently meet the putative clinically meaningful differences for both ET and IC and, in this respect, are superior to their monocomponents.

  18. Y-chromosome and mtDNA variation confirms independent domestications and directional hybridization in South American camelids.

    2017-10-01

    Investigations of genetic diversity and domestication in South American camelids (SAC) have relied on autosomal microsatellite and maternally-inherited mitochondrial data. We present the first integrated analysis of domestic and wild SAC combining male and female sex-specific markers (male specific Y-chromosome and female-specific mtDNA sequence variation) to assess: (i) hypotheses about the origin of domestic camelids, (ii) directionality of introgression among domestic and/or wild taxa as evidence of hybridization and (iii) currently recognized subspecies patterns. Three male-specific Y-chromosome markers and control region sequences of mitochondrial DNA are studied here. Although no sequence variation was found in SRY and ZFY, there were seven variable sites in DBY generating five haplotypes on the Y-chromosome. The haplotype network showed clear separation between haplogroups of guanaco-llama and vicuña-alpaca, indicating two genetically distinct patrilineages with near absence of shared haplotypes between guanacos and vicuñas. Although we document some examples of directional hybridization, the patterns strongly support the hypothesis that llama (Lama glama) is derived from guanaco (Lama guanicoe) and the alpaca (Vicugna pacos) from vicuña (Vicugna vicugna). Within male guanacos we identified a haplogroup formed by three haplotypes with different geographical distributions, the northernmost of which (Peru and northern Chile) was also observed in llamas, supporting the commonly held hypothesis that llamas were domesticated from the northernmost populations of guanacos (L. g. cacilensis). Southern guanacos shared the other two haplotypes. A second haplogroup, consisting of two haplotypes, was mostly present in vicuñas and alpacas. However, Y-chromosome variation did not distinguish the two subspecies of vicuñas. © 2017 Stichting International Foundation for Animal Genetics.

    The growing demand for complementary medicine practices has led to research related to mud therapy that is the use of peloid for therapeutic treatment. In Brazil, this practice is used in the city of Peruíbe for the application of Peruíbe's Black Lama (LNP) for cutaneous and rheumatic conditions. The LNP deposit was studied in this work with the objective of verifying its homogeneity regarding elemental chemical composition, since it is collected at different points of the deposit for application in patients. The results showed that the differences between the several sampling points and between the in natura and maturate sludge are small and not significant, thus, it can be considered that the LNP deposit is homogeneous with respect to its elemental composition

    Prior studies have demonstrated tumor-specific alternative splicing events in various solid tumor types. The role of alternative splicing in the development and progression of head and neck squamous cell carcinoma (HNSCC) is unclear. Our study queried exon-level expression to implicate splice variants in HNSCC tumors. We performed a comparative genome-wide analysis of 44 HNSCC tumors and 25 uvulopalatopharyngoplasty (UPPP) tissue samples at an exon expression level. In our comparison we ranked genes based upon a novel score-the Maximum-Minimum Exon Score (MMES)--designed to predict the likelihood of an alternative splicing event occurring. We validated predicted alternative splicing events using quantitative RT-PCR on an independent cohort. After MMES scoring of 17,422 genes, the top 900 genes with the highest scores underwent additional manual inspection of expression patterns in a graphical analysis. The genes LAMA3, DST, VEGFC, SDHA, RASIP1, and TP63 were selected for further validation studies because of a high frequency of alternative splicing suggested in our graphical analysis, and literature review showing their biological relevance and known splicing patterns. We confirmed TP63 as having dominant expression of the short DeltaNp63 isoform in HNSCC tumor samples, consistent with prior reports. Two of the six genes (LAMA3 and DST) validated by quantitative RT-PCR for tumor-specific alternative splicing events (Student's t test, P<0.001). Alternative splicing events of oncologically relevant proteins occur in HNSCC. The number of genes expressing tumor-specific splice variants needs further elucidation, as does the functional significance of selective isoform expression.

    Defects in genes encoding the isoforms of the laminin alpha subunit have been linked to various phenotypic manifestations, including brain malformations, muscular dystrophy, ocular defects, cardiomyopathy, and skin abnormalities. We report here a severe defect of neuromuscular transmission in a consanguineous patient with a homozygous variant in the laminin alpha-5 subunit gene (LAMA5). The variant c.8046C>T (p.Arg2659Trp) is rare and has a predicted deleterious effect. The affected individual, who also carries a rare homozygous sequence variant in LAMA1, had muscle weakness, myopia, and facial tics. Magnetic resonance imaging of brain showed mild volume loss and periventricular T2 prolongation. Repetitive nerve stimulation revealed 50% decrement of compound muscle action potential amplitudes and 250% facilitation immediately after exercise, Endplate studies identified a profound reduction of the endplate potential quantal content and endplates with normal postsynaptic folding that were denuded or partially occupied by small nerve terminals. Expression studies revealed that p.Arg2659Trp caused decreased binding of laminin alpha-5 to SV2A and impaired laminin-521 cell-adhesion and cell projection support in primary neuronal cultures. In summary, this report describing severe neuromuscular transmission failure in a patient with a LAMA5 mutation expands the list of phenotypes associated with defects in genes encoding alpha-laminins. © 2017 Wiley Periodicals, Inc.

    The objectives of this work were to assess the mtDNA diversity of Bolivian South American camelid (SAC) populations and to shed light on the evolutionary relationships between the Bolivian camelids and other populations of SACs. We have analysed two different mtDNA regions: the complete coding region of the MT-CYB gene and 513 bp of the D-loop region. The populations sampled included Bolivian llamas, alpacas and vicunas, and Chilean guanacos. High levels of genetic diversity were observed in the studied populations. In general, MT-CYB was more variable than D-loop. On a species level, the vicunas showed the lowest genetic variability, followed by the guanacos, alpacas and llamas. Phylogenetic analyses performed by including additional available mtDNA sequences from the studied species confirmed the existence of the two monophyletic clades previously described by other authors for guanacos (G) and vicunas (V). Significant levels of mtDNA hybridization were found in the domestic species. Our sequence analyses revealed significant sequence divergence within clade G, and some of the Bolivian llamas grouped with the majority of the southern guanacos. This finding supports the existence of more than the one llama domestication centre in South America previously suggested on the basis of archaeozoological evidence. Additionally, analysis of D-loop sequences revealed two new matrilineal lineages that are distinct from the previously reported G and V clades. The results presented here represent the first report on the population structure and genetic variability of Bolivian camelids and may help to elucidate the complex and dynamic domestication process of SAC populations. © 2012 The Authors, Animal Genetics © 2012 Stichting International Foundation for Animal Genetics.

    Full Text Available A polychrome wooden sculpture from the Museum of Santa Maria de Lamas (Northern Portugal, representing the image of Saint Dominic, produced in the first half of the 18th century, was studied for the identification of the materials and techniques employed in its fine modelling. Radiography was used for the study of the construction details of the wooden support, optical microscopy (OM and polarized light microscopy (PLM for the characterization of the paint layers and energy dispersive X-ray spectrometry (EDXRF, Fourier transform infrared spectroscopy (FTIR and microchemical tests for the identification of pigments and fillers.The identified materials were common to the period when the sculpture was made: gypsum, gold leaf, bole,white lead, brown ochre, vermillion, a black pigment made of carbon (possibly mixed with verdigris, used as a drier, a red lake and a calcium compound used as filler. However, regarding the techniques employed, and probably due to economic reasons, it seems that the recommended practice in art treatises and working contracts was not completely followed in what concerns the ground layers. Similar reasons appear to have caused the use of white lead mixed with a calcium compound, as a filler, in the less expressive areas, and should explain the fact that the estofado techniques (simulation of brocaded vestment have been limited to the visible areas at the front.

    Our study falls in line with the numerous studies providing a critique of the use of western diagnostic instruments for assessing trauma in a cross-cultural context. Our purpose has been to give evidence for the Tibetan torture survivors' degree of traumatisation and for their use of spirituality to overcome their difficult situation. In addition we wanted to question the use of our western methods in an Asian context. 102 tortured refugees attended a formalised needs assessment including neuropsychological and psychological measures of Post Traumatic Stress Disorder (PTSD) and the Hopkins Symptom Checklist 25 (HSCL-25). Even though significant correlations between the amount of the measures of organized violence and neuropsychological and psychological distress were found in our data, the division of the material into different subgroups according to e.g. religious and non-religious groups did not have an influence on the level of distress. After the assessment study, eight Tibetan lamas were interviewed about their views on our methods and results. They questioned the validity of our western rating scales and explained that our results might be influenced by the Tibetan culture, which among other things can be characterized as having a view and articulation of suffering much more complex than the units of our study's rating scales.

    Full Text Available In wild-living populations adult camelids are mainly sexed by observing their social and reproductive behavior, and on occasion, their genitalia. Both biologists and archaeologists usually assume the absence of clearly identifiable sexually dimorphic somatic and postcranial traits among adult guanaco (Lama guanicoe specimens. The principal studies that evaluate the osteological differences between sexes in this species, had been carried out using qualitative morphological traits of the pelvis and morphometric traits of the skull. Therefore, the main objective of this paper is to contribute to the development of methodological tools aimed to accurately discriminate between sexes using morphometric techniques. In addition, we assess in this paper the existence and magnitude of the postcranial sex-related morphometric differences in a sample of modern guanaco specimens from Cinco Chañares, Río Negro, Argentina. The sample was composed by 32 individuals (8 males and 24 females older than 30 month at the age of death. Fifty one hemipelvis, 40 humeri, 39 radioulnae, 40 femora, and 41 tibiae were measured. The obtained results show that the main morphometric differences between sexes are related to size and shape variation in the whole pelvis and acetabulum. In the appendicular skeleton no statistically significant differences between sexes were found, but this ought to be reevaluated increasing sample sizes of male specimens.

    Reports of CMhl infections in South American Camelids in Europe are only available from the United Kingdom and Switzerland. Knowing that CMhl infections can lead to severe disease resulting in death if combined with other diseases or stress, it was the aim of this study to assess prevalence data from camelids in Austria. In comparison to the previous studies a representative number of camelids was investigated nationwide. Data were assessed due to differences in geographical region, age, sex, species, and origin. A relatively high prevalence of 25.8% was recorded. CMhl was detected significantly more often in alpacas (Vicunja pacos) than in llamas (Lama glama) and more frequently in animals younger than 2 years. Additionally regional differences have been observed, which might be due to climatic differences and/or variations in insect vectors. In this study apperantly clinical healthy animals were shown to be infected with CMhl. Camelids infected with CMhl are a pathogen reservoir. The results of this study indicate different risk levels of infection between llamas and alpacas and between younger and older animals. The data presented underline the necessity of further studies on CMhlI infections in South American Camelids.

Los principales estudios que evalúan las diferencias osteológicas entre machos y hembras en esta especie están basados en análisis de variables morfométricas craneanas y en caracteres morfológicos de la pelvis. En este trabajo se evalúa la existencia y magnitud de variables osteométricas poscraneales de diferenciación sexual en una población moderna de guanacos procedente de la localidad Cinco Chañares, Provincia de Río Negro, Argentina. Se estudiaron 32 individuos (8 machos y 24 hembras de más de 30 meses en los que se midieron 51 hemipelvis, 40 húmeros, 39 radioulnas, 40 fémures y 41 tibias. Los resultados mostraron que las principales diferencias osteológicas, vinculadas con el dimorfismo sexual, se relacionan con variaciones en el tamaño y la forma de la pelvis.

    Potential therapies are currently under development for two congenital muscular dystrophy (CMD) subtypes: Collagen VI Related Myopathy (COL6-RM) and Laminin α2-related dystrophy (LAMA2-RD). However, appropriate clinical outcome measures to be used in clinical trials have not been validated in CMDs. We conducted a two-year pilot study to evaluate feasibility, reliability, and validity of various outcome measures, particularly the Motor Function Measure 32, in 33 subjects with COL6-RM and LAMA2-RD. In the first year, outcome measures tested included: Motor Function Measure 32 (MFM32), forced vital capacity (FVC) percent predicted sitting, myometry, goniometry, 10-meter walk, Egen Klassification 2, and PedsQL™ Generic and Neuromuscular Cores. In the second year, we added the North Star Ambulatory Assessment (NSAA), Hammersmith Functional Motor Scale (HFMS), timed functional tests, Measure of Activity Limitations (ACTIVLIM), Quality of Upper Extremity Skills Test (QUEST), and Patient-Reported Outcomes Measurement Information System (PROMIS) fatigue subscale. The MFM32 showed strong inter-rater (0.92) and internal consistency (0.96) reliabilities. Concurrent validity for the MFM32 was supported by large correlations (range 0.623–0.936) with the following: FVC, NSAA, HFMS, timed functional tests, ACTIVLIM, and QUEST. Significant correlations of the MFM32 were also found with select myometry measurements, mainly of the proximal extremities and domains of the PedsQL™ scales focusing on physical health and neuromuscular disease. Goniometry measurements were less reliable. The Motor Function Measure is reliable and valid in the two specific subtypes of CMD evaluated, COL6-RM and LAMA2-RD. The NSAA is useful as a complementary outcome measure in ambulatory individuals. Preliminary concurrent validity of several other clinical outcome measures was also demonstrated for these subtypes.

    The llama (Lama glama) is one of the few mammals of relatively large body size in which three fast myosin heavy chain isoforms (i.e., IIA, IIX, IIB) are extensively expressed in their locomotory muscles. This study was designed to gain insight into the morphological and functional organization of skeletal musculature in this peculiar animal model. The neuromuscular partitioning, architectural design, and myosin fiber types were systematically studied in the M. vastus lateralis of adult llamas (n = 15). Four nonoverlapping neuromuscular partitions or compartments were identified macroscopically (using a modified Sihler's technique for muscle depigmentation), although they did not conform strictly to the definitions of "neuromuscular compartments." Each neuromuscular partition was innervated by primary branches of the femoral nerve and was arranged within the muscle as paired partitions, two in parallel (deep-superficial compartmentalization) and the other two in-series (proximo-distal compartmentalization). These neuromuscular partitions of the muscle varied in their respective architectural designs (studied after partial digestion with diluted nitric acid) and myosin fiber type characteristics (identified immunohistochemically with specific anti-myosin monoclonal antibodies, then examined by quantitative histochemistry and image analysis). The deep partitions of the muscle had longer fibers, with lower angles of pinnation, and higher percentages of fast-glycolytic fibers than the superficial partitions of the muscle. These differences clearly suggest a division of labor in the whole M. vastus lateralis of llamas, with deep partitions exhibiting features well adapted for dynamic activities in the extension of stifle, whereas superficial portions seem to be related to the antigravitational role of the muscle in preserving the extension of the stifle during standing and stance phase of the stride. This peculiar structural and functional organization of the llama M

    Like other camelids, llamas (Lama glama) have the natural ability to pace (moving ipsilateral limbs in near synchronicity). But unlike the Old World camelids (bactrian and dromedary camels), they are well adapted for pacing at slower or moderate speeds in high-altitude habitats, having been described as good climbers and used as pack animals for centuries. In order to gain insight into skeletal muscle design and to ascertain its relationship with the llama's characteristic locomotor behaviour, this study examined the correspondence between architecture and fibre types in two agonist muscles involved in shoulder flexion (M. teres major - TM and M. deltoideus, pars scapularis - DS and pars acromialis - DA). Architectural properties were found to be correlated with fibre-type characteristics both in DS (long fibres, low pinnation angle, fast-glycolytic fibre phenotype with abundant IIB fibres, small fibre size, reduced number of capillaries per fibre and low oxidative capacity) and in DA (short fibres, high pinnation angle, slow-oxidative fibre phenotype with numerous type I fibres, very sparse IIB fibres, and larger fibre size, abundant capillaries and high oxidative capacity). This correlation suggests a clear division of labour within the M. deltoideus of the llama, DS being involved in rapid flexion of the shoulder joint during the swing phase of the gait, and DA in joint stabilisation during the stance phase. However, the architectural design of the TM muscle (longer fibres and lower fibre pinnation angle) was not strictly matched with its fibre-type characteristics (very similar to those of the postural DA muscle). This unusual design suggests a dual function of the TM muscle both in active flexion of the shoulder and in passive support of the limb during the stance phase, pulling the forelimb to the trunk. This functional specialisation seems to be well suited to a quadruped species that needs to increase ipsilateral stability of the limb during the support

    Full Text Available Abstract Background Llamas (Lama glama are induced ovulators and the process of ovulation depends on dominant follicular size. In addition, a close relationship between behavioural estrus and ovulation is not registered in llamas. Therefore, the exogenous control of follicular development with hormones aims to predict the optimal time to mate. Oestradiol-17β (E2 and its esters are currently used in domestic species, including camelids, in synchronization treatments. But, in llamas, there is no reports regarding the appropriate dosages to be used and most protocols have been designed by extrapolation from those recommended for other ruminants. The aim of the present study was to characterize plasma E2 concentrations in intact female llamas following a single intramuscular (i.m. injection of two oestradiol esters: oestradiol benzoate (EB and oestradiol cypionate (ECP. Methods Twelve non pregnant and non lactating sexually mature llamas were i.m. injected on day 0 with 2.5 mg of EB (EB group, n = 6 or ECP (ECP group, n = 6. Blood samples were collected immediately before injection, at 1, 6, 12, 24 h after treatment and then daily until day 14 post injection. Changes in hormone concentrations with time were analyzed in each group by analysis of variance (ANOVA using a repeated measures (within-SS design. Plasma E2 concentrations and area under the concentration-time curve (AUC values were compared between groups by ANOVA. In all cases a Least-Significant Difference test (LSD was used to determine differences between means. Hormonal and AUC data are expressed as mean ± S.E.M. Results Peak plasma E2 concentrations were achieved earlier and were higher in EB group than in ECP group. Thereafter, E2 returned to physiological concentrations earlier in EB group (day 5 than in ECP group (day 9.

    Full Text Available RESUMO: A produção de concreto em usinas dosadoras está em crescimento e, com isso, há também o aumento de resíduos inerentes do processo produtivo. O objetivo deste artigo, é verificar o panorama das pesquisas relacionadas com a lama residual de concreto, com ênfase na sua reciclagem em unidades de alvenaria. Para tanto, foi realizado o mapeamento sistêmico com a finalidade de encontrar as principais publicações e estudos referentes a vertente desejada, através da base de dados Periódicos CAPES, sendo as buscas pertencentes a dois tópicos principais: utilização de resíduos em alvenarias de concreto e estudos relacionados com a lama residual de concreto. Em linhas gerais, pode-se observar que há uma grande variedade de resíduos aplicados em alvenarias, sendo o mais estudado a utilização de cinzas volantes e resíduos de construção e demolição. Em contrapartida, ainda são poucos os estudos que utilizam a lama residual em produtos de concreto, sobretudo para produção de alvenarias. Nesse contexto, entende-se que não há um consenso quanto à melhor utilização da lama residual de concreto, ressaltando a necessidade de pesquisas que corroborem ou contradigam os resultados obtidos. Por fim, esse trabalho aponta um resíduo ainda pouco estudado, mas com possíveis aplicações em novas pesquisas. Suas características como, por exemplo, presença de SiO2 e CaO apontam um potencial para uso como aglomerante, o que pode gerar uma redução no consumo de cimento. ABSTRACT: The production of concrete in dosing plants is growing and, with this, there is also an increase of inherent residues of the production process.

    2009-07-01

    We present the results of a palaeogenetic analysis of two Late Pleistocene camelids originating in southern Chile. Our analysis of two mitochondrial DNA fragments (control region and cytochrome b gene) reveals that these specimens do not belong to an extinct taxon, but rather to extant vicuña ( Vicugna vicugna), whose modern distribution is restricted to the extreme elevations of the Andes, more than 3500 km to the north of where these specimens originated. Our results also suggest fossil specimens from Patagonia that are currently assigned to the extinct taxon Lama gracilis, may actually belong to V. vicugna, implying a continuous distribution of the latter from the southern tip of South America to the Andes during the Final Pleistocene. The haplotypes of both specimens are not present in modern populations, suggesting a loss of genetic diversity concomitant with the contraction of the vicuña geographical distribution during the Final Pleistocene or early Holocene.

    Full Text Available The present study sought to observe the behavior of soils in natural state and in mixtures, in different ratios, with the industrial solid residue called whitewash mud. The work was conducted with samples of typical soils from the region of Alagoinhas, Bahia-Brazil. Wet chemical analysis and atomic absorption spectrophotometry were used in order to obtain the classification of the industrial solid residue. Solubilization and leaching tests were performed and X-ray diffraction and electron microscopy techniques were carried out. The results showed that the whitewash mud was classified as non-inert, but with great capacity of heavy metal retention largely owed to the kaolinite and goethite presence in the clay fraction of the soils, making it difficult to have heavy metals readily available for exchange.O presente estudo buscou observar o comportamento de solos em seu estado natural e em misturas, em diferentes teores, com o resíduo sólido industrial denominado lama-de-cal. A pesquisa foi conduzida com amostras de solos típicas da região de Alagoinhas, Bahia-Brasil. A análise química por via úmida e espectrofotometria de absorção atômica foram usadas para obter a classificação do resíduo sólido industrial. Testes de solubilização, lixiviação, analise de raios X e microscopia eletrônica de varredura foram executados. Os resultados indicaram que a lama-de-cal não é inerte, mas com grande capacidade de retenção de metais pesados, em grande parte devido à presença de caulinita e goethita na fração argila dos solos.

    The growing demand for complementary medicine practices has led to research related to mud therapy that is the use of peloid for therapeutic treatment. In Brazil, this practice is used in the city of Peruíbe for the application of Peruíbe's Black Lama (LNP) for cutaneous and rheumatic conditions. The LNP deposit was studied in this work with the objective of verifying its homogeneity regarding elemental chemical composition, since it is collected at different points of the deposit for application in patients. The results showed that the differences between the several sampling points and between the in natura and maturate sludge are small and not significant, thus, it can be considered that the LNP deposit is homogeneous with respect to its elemental composition.

    Guanacos (Lama guanicoe) are large ungulates that have been valued by human populations in South America since the Late Pleistocene. Even though they were very abundant until the end of the 19th century (before the high deforestation rate of the last decades), guanacos have nearly disappeared in the Gran Chaco ecoregion, with relicts and isolated populations surviving in some areas, such as the shrubland area near the saline depressions of Córdoba province, Argentina. In this report, we present the first data from a locally endangered guanaco wild population, through the study of skeletal remains recovered in La Providencia ranch. Our results showed that most of the elements belonged to adults aged between 36 and 96 months; sex evaluation showed similar numbers of males and females. Statistical analysis of the body size of modern samples from Córdoba demonstrated that guanacos from the Chaco had large dimensions and presented lower size variability than the modern and archaeological specimens in our database. Moreover, they exhibited dimensions similar to those of modern guanacos from Patagonia and San Juan, and to archaeological specimens from Ongamira and Cerro Colorado, although further genetic studies are needed to corroborate a possible phylogenetic relationship. Finally, we used archaeozoological techniques to provide a first characterization of a relict guanaco population from the Chaco ecoregion, demonstrating its value to the study of modern skeletal remains and species conservation biology.

    A late epoch cosmic acceleration may be naturally entangled with cosmic coincidence--the observation that at the onset of acceleration the vacuum energy density fraction nearly coincides with the matter density fraction. In this Letter we show that this is indeed the case with the cosmology of a Friedmann-Lamaître-Robertson-Walker (FLRW) 3-brane in a five-dimensional anti-de Sitter spacetime. We derive the four-dimensional effective action on a FLRW 3-brane, from which we obtain a mass-reduction formula, namely, M(P)(2) = ρ(b)/|Λ(5)|, where M(P) is the effective (normalized) Planck mass, Λ(5) is the five-dimensional cosmological constant, and ρ(b) is the sum of the 3-brane tension V and the matter density ρ. Although the range of variation in ρ(b) is strongly constrained, the big bang nucleosynthesis bound on the time variation of the effective Newton constant G(N) = (8πM(P)(2))(-1) is satisfied when the ratio V/ρ ≳ O(10(2)) on cosmological scales. The same bound leads to an effective equation of state close to -1 at late epochs in accordance with astrophysical and cosmological observations.

    Bluetongue (BT) is an infectious, non-contagious disease of wild and domestic ruminants. It is caused by bluetongue virus (BTV) and transmitted by Culicoides biting midges. Since 1998, BT has been emerging throughout Europe, threatening not only the naïve ruminant population. Historically, South American camelids (SAC) were considered to be resistant to BT disease. However, recent fatalities related to BTV in captive SAC have raised questions about their role in BTV epidemiology. Data on the susceptibility of SAC to experimental infection with BTV serotype 8 (BTV-8) were collected in an animal experiment. Three alpacas (Vicugna pacos) and three llamas (Lama glama) were experimentally infected with BTV-8. They displayed very mild clinical signs. Seroconversion was first measured 6-8 days after infection (dpi) by ELISA, and neutralising antibodies appeared 10-13 dpi. BTV-8 RNA levels in blood were very low, and quickly cleared after seroconversion. However, spleens collected post-mortem were still positive for BTV RNA, over 71 days after the last detection in blood samples. Virus isolation was only possible from blood samples of two alpacas by inoculation of highly sensitive interferon alpha/beta receptor-deficient (IFNAR(-/-)) mice. An in vitro experiment demonstrated that significantly lower amounts of BTV-8 adsorb to SAC blood cells than to bovine blood cells. Although this experiment showed that SAC are generally susceptible to a BTV-8 infection, it indicates that these species play a negligible role in BTV epidemiology. Copyright © 2011 Elsevier B.V.

    Full Text Available Connectivity between populations plays a key role in the long-term persistence of species in fragmented habitats. This is of particular concern for biodiversity preservation in drylands, since water limited landscapes are typically characterized by little suitable habitat cover, high habitat fragmentation, harsh matrices, and are being rapidly degraded at a global scale. In this study, we modelled landscape connectivity between 11 guanaco Lama guanicoe populations in Chile’s arid Norte Chico, a region that supports the last remnant coastal populations of this emblematic herbivore indigenous to South America. We produced a habitat suitability model to derive a regional surface resistance map, and used circuit theory to map functional connectivity, investigate the relative isolation between populations, and identify those that contribute most to the patch connectivity network. Predicted suitable habitat for L. guanicoe represented about 25% of the study region (i.e., 29,173 km2 and was heterogeneously distributed along a continuous stretch along the Andes, and discontinuous patches along the coast. As a result, we found that high connectivity current flows in the mid and high Andes formed a wide, continuous connectivity corridor, enabling connectivity between all high Andean populations. Coastal populations, in contrast, were more isolated. These groups demonstrate no inter-population connectivity between themselves, only with higher altitude populations, and for two of them, animal movement was linked to the effectiveness of wildlife crossings along the Pan-American highway. Our results indicate that functional connectivity is an issue of concern for L. guanicoe in Chile’s Norte Chico, implying that future conservation and management plans should emphasize strategies aimed at conserving functional connectivity between coastal and Andean populations, as well as the protection of habitat patches likely to act as stepping stones within the

    Llamas (Lama glama) are intermediate hosts of the protozoan parasite Sarcocystis spp. This parasite is described as causing economic losses in the production of llama meat in South America. The aim of this study was to estimate prevalence, identify risk factors and explore spatial patterns of Sarcocystis in llamas in an area of the Bolivian High Plateau including estimating financial losses due to carcass downgrades as a result of the presence of Sarcocystis cysts. Information was collected from a local abattoir between 2006 and 2011 on 1196 llamas. Sarcocystis status was determined at meat inspection where any carcasses with one or more visible cysts were deemed Sarcocystis positive. A high prevalence was found, estimated to vary between 23.4% (95% CI 16.6-30.1) in 2007 and 50.3% (95% CI 44.4-56.3) in 2011. Period prevalence between 2006 and 2011 was estimated at 34.1% (95% CI 31.4-36.8). Age, sex and type (analogous to breed) were identified as risk factors for Sarcocystis using a mixed-effects logistic regression model adjusting for clustering by community and owner. Llamas over 4.5 years of age had an increased odds of being Sarcocystis positive (OR 19.31, 95% CI 9.10-40.98) as well as females (OR 1.75, 95% CI 1.13-2.68) and long haired type llamas (OR 1.90, 95% CI 1.26-2.87). An interaction between age and sex was detected indicating that the increased odds of disease from the youngest age group to the 2.5-4.5 years group was much more pronounced in females than in males. Spatial patterns of Sarcocystis were explored at district level by means of Standardised Morbidity Ratios and some spatial heterogeneity was revealed. Estimates of financial loss due to the disease were calculated using the difference in price paid for Sarcocystis positive and negative meat. Loss due to Sarcocystis varied per year but could be up to 20% of the annual income generated through the abattoir by sale of meat. Overall this study shows a high prevalence of Sarcocystis in the study

A neutralização da lama vermelha é necessária porque essa lama é tipicamente cáustica, com pH em torno de 13. Muitas pesquisas têm sido desenvolvidas envolvendo a utilização da lama vermelha, porque contem uma série de elementos valiosos. Assim a utilização da lama vermelha como material de construção e como adsorvente é atrativa porque ela é utilizada em grande quantidade. Nada pode ser feito sem descartar componentes valiosos como titânio, zircônio e principalmente ferro. A síntese de hidrotalcita conectada com a reciclagem de soluções alcalinas representa uma maneira efetiva de uso dessa solução considerando a forte demanda por proteção ambiental no mundo. Os compostos tipo hidrotalcita, precipitados durante a neutralização da lama, também removem oxi-ânions de metais de transição através da combinação de intercalações e adsorção de espécies aniônicas na sua superfície externa. Os hidróxidos duplos lamelares (HDL vêm sendo investigados à muitos anos como materiais hospedeiros para uma variedade de reações de intercalação de anions. A estrutura lamelar dos HDLs pode ser usada para controlar a adição ou remoção de uma variedade de espécies químicas, tanto orgânicas quanto inorgânicas. Isto é alcançado através de sua habilidade de adaptar a separação das lamelas de hidróxidos, e da reatividade da região interlamelar. O material resultante adsorve anions quando colocado em soluções e reverte a estrutura da hidrotalcita. Avanços significativos têm sido alcançados recentemente na caracterização desses materiais, incluindo estudos estruturais sobre o mecanismo de intercalação. O objetivo desse trabalho foi a síntese e caracterização de HDLs a partir da lama vermelha, e

    Hair fibre is regarded as a unique mammalian feature with an important role for endothermy. Artificial selection for hair characteristics resulted in marked changes with regard to follicle number, type, distribution, growth and natural shedding. This review focuses on the fine fibre-producing South American camelids (SACs) and the relationship between their hair coat and thermoregulation. SACs have developed several special integumental characteristics. While the hair coat of the wild lamoids vicuña (Vicugna vicugna) and guanaco (Lama guanicoe) is formed by two types of hair (the coarse outer guard hairs and a finer undercoat), the domesticated llamas (Lama glama) and alpaca (Lama pacos) exhibit variably double coat and predominantly single coat, respectively. The distribution of the hair coat across the body is not homogenous. Thermal windows with shorter hair or thinner skin can be identified at the ventral abdomen, axillary space and inside of the thighs (about 20% of the skin), thus allowing to modulate heat dissipation. In contrast to sheep wool, lamoid fibres are mainly medullated. The thermal conductance of summer pelage was higher than that of the winter fleece and highest for the axillar and lower flanks. Lamoids have developed behavioural strategies to modify heat loss by adopting specific postures according to ambient conditions by closing or opening the thermal windows. Energy savings of 67% attributed to posture were calculated. SACs have shown to be able to adapt to a broad range of different climatic conditions. The specific integumental characteristics of SACs indicate that they have developed adaptation mechanisms particularly suited for cooler climates. Accordingly, hyperthermia might become a problem in hot, humid areas outside of their original habitat. Several studies showed the beneficial effect of shearing against heat stress. In particular, fertility in males exposed to heat stress may be improved by shearing. Infrared thermography reveals

No presente trabalho, estudou-se a lama vermelha, resíduo sólido gerado no processo de beneficiamento da bauxita e que, devido a seu elevado pH, é considerado "perigoso". Apesar do uso deste resíduo ter sido reportada em trabalhos anteriores, algumas patologias podem estar associadas à sua utilização, devido à elevada concentração de íons alcalinos (principalmente o sódio, favorecendo as reações álcalis-sílica (RAS e às dificuldades de moldagem (reologia devido à elevada finura deste resíduo. Apesar destes prováveis problemas provenientes do uso indiscriminado da lama vermelha como adição às argamassas e concretos, ainda são poucas as pesquisas que os contemplam, sendo este o foco do presente trabalho.

    Llama (Lama glama) and alpaca (Vicugna pacos) are the only large domesticated animals indigenous to the Americas. Pastoralism occupies a fundamental economic, social and religious role in Andean life. Today, camelid livestock are confined to the ecozone of the puna (above 3,500 masl), while their presence on the Pacific coast during pre-Hispanic times is attested by archaeological skeletal remains. This study aims to document herding practices on the northern Peruvian coast during the Early Intermediate Period (200 BC-600 AD) by gaining insights into diet, location of breeding and mobility of archaeological camelids from the funerary and ritual contexts of two Mochica sites, Uhle Platform in Huacas de Moche and El Brujo. The three first early years and the long-term life histories of the animals were documented by the combined bulk analysis of bone collagen (δ13Ccol and δ15Ncol) and bone structural carbonate (δ13Cbone and δ18Obone) and the serial analysis of structural carbonate of molar tooth enamel (δ13Cenamel and δ18Oenamel). Mochica camelids were bred in the low and/or middle valleys, unlike their modern counterparts, who are restricted to highland puna C3 pastures. Archaeological camelids had diverse and complex life histories, usually with substantial maize foddering. An ontogenetic switch in diet and possible residential mobility during the course of life were identified for some specimens. Although the inference of geographic origin from δ18Obone and δ18Oenamel values was limited because of the lack of understanding of the influence of environmental and biological factors, tooth enamel analysis has great potential for exploring camelid herding practices and Andean pastoralism. Our study suggested that Mochica herders adapted their practices to the difficult lowland environment and that herding practices were varied and not restricted to breeding at higher altitudes. The role of maize in different aspects of the economic life of the Mochicas is also

    In this study, the placental localization of PAG-like transcripts and genomic existence of PAG-like amplicons in new-world (Lp, Lama pacos, alpaca) and old-world camelids (Cb, Camelus bactrianus, bactrian; Cd, Camelus dromedarius; dromedary) are reported for the first time. Sections of Lp (150-347 days post coitum), Cd (43-90 cm crown-rump length) and Cb (term) placentas were used for heterologous (ht; cross-species) autoradiographic in situ hybridization (aISH) with single-stranded diagnostic (antisense) or control (sense) [alpha-(35)S]dATP-labeled 323 nt porcine PAG8 (pPAG8) cDNA probes produced by asymmetric PCRs. The aISH with antisense (35)S-pPAG8 probe identified camelid PAG-like (LpPAG, CbPAG and CdPAG) mRNA expression restricted to chorionic epithelium cells within placentas of camelids. In addition, genomic DNA (gDNA), isolated from placental sections were used as templates for camelid PAG-like gene amplicon production by PCR. Specificity of the obtained multiple camelid gDNA PAG-like amplicons was confirmed by double ht-Southern hybridizations with [alpha-(32)P]dATP-labeled 611 bp pPAG5 and pPAG10 double-stranded cDNA probes. The double ht-Southern hybridizations of camelid gDNA amplicons (with pPAG5 and -10 probes) allowed the identification of length-polymorphism of LpPAG, CbPAG and CdPAG genes, coding catalytically active and potentially inactive forms. Such an application of porcine PAG probes may be advantageous for future identification of still undiscovered PAG-like families in other eutherian species.

    The high grasslands of Apolobamba provide a natural habitat for a high number of wild and domestic camelids such as vicuna (Vicugna vicugna) and alpaca (Lama pacos) in Bolivia. Because of the importance of the camelid raising for the Apolobambás inhabitant economy, it is fundamental to determine the natural resources condition and their availability for the camelid support. The soil organic matter plays a crucial role in the maintenance of the soil fertility at high grasslands. On the other hand, soil respiration is the primary pathway for CO2 fixed by plants returning to the atmosphere and its study is essential to evaluate the soil organic matter mineralization and the global C cycle. Based on this, the objectives of this research were to: (i) evaluate the soil fertility and (ii) determine soil organic matter mineralization on the basis of CO2 releases in Apolobamba. Regarding the lastly vicuna censuses carried out in the studied area, eight representative zones with dissimilar vicuna densities were selected. Other characteristics were also considered to select the study zones: (1) alpaca densities, (2) vegetation communities (3) plant cover and (4) landscape and geo-morphological description. Soil samples from different samplings were collected. Soil respiration was determined at two temperatures: 15 °C (based on the highest atmosphere temperature that was registered in the area) and 25 °C, in order to monitor the increase in soil respiration (Q10). The physico-chemical soil results pointed out the good soil fertility. However, erosive processes could be taken place likely caused by the alpaca grazing. High total organic carbon contents were observed corresponding to the highest soil respiration at 15 °C. This observation was supported by the relationship found between the total organic carbon and the soil respiration. A noticeable increase of the soil respiration when the temperature increased 10 °C was reported (from 1083 ± 47 g C m-2 yr-1 at 15 °C to

    Full Text Available A aplicação de lamas residuais urbanas (LRU aos solos destinados a pastagens, ainda escassamente utilizada no País, contribui, com frequência, para melhorar os níveis de matéria orgânica (M.O. e de alguns nutrientes das plantas e para diminuir o risco de erosão, pelo aumento da cobertura vegetal. Todavia, a presença eventual de níveis elevados de metais pesados, compostos orgânicos poluentes e organismos patogénicos nas LRU condiciona a dose a aplicar e torna imprescindível o controlo desses factores nos solos aos quais foram incorporadas. Também o teor elevado de azoto que por vezes contêm pode inibir a actividade simbiótica do rizóbio, prejudicando a sobrevivência das leguminosas na pastagem. Neste trabalho, examinaram-se a produção de matéria seca, a composição florística e o teor de cobre (Cu na biomassa vegetal, em dois anos consecutivos de um ensaio com uma mistura pratense semeada para cortes sucessivos, instalado, no Outono de 2001, num Luvissolo Háplico de baixa fertilidade, em Mértola, ao qual foi aplicado LRU secundária proveniente da ETAR de Évora, com um elevado teor de Cu. No mesmo período, apreciou-se a evolução, na camada superficial do solo, dos teores de M.O., de alguns macronutrientes e do Cu extraível por água régia. Avaliouse, ainda, a grandeza da população rizobiana que nodula o trevo (Rhizobium leguminosarum biovar trifolii e procedeu-se à prospecção de indicadores de contaminação fecal (bactérias coliformes e enterococos. No ano seguinte à aplicação da LRU, examinou-se a evolução, no solo, de 11 compostos bifenilospoliclorados (PCBs, 13 pesticidas organoclorados e 16 hidrocarbonetos aromáticos polinucleares (PAHs.

    Elise Dufour

    Full Text Available Llama (Lama glama and alpaca (Vicugna pacos are the only large domesticated animals indigenous to the Americas. Pastoralism occupies a fundamental economic, social and religious role in Andean life. Today, camelid livestock are confined to the ecozone of the puna (above 3,500 masl, while their presence on the Pacific coast during pre-Hispanic times is attested by archaeological skeletal remains. This study aims to document herding practices on the northern Peruvian coast during the Early Intermediate Period (200 BC-600 AD by gaining insights into diet, location of breeding and mobility of archaeological camelids from the funerary and ritual contexts of two Mochica sites, Uhle Platform in Huacas de Moche and El Brujo. The three first early years and the long-term life histories of the animals were documented by the combined bulk analysis of bone collagen (δ(13C col and δ(15N col and bone structural carbonate (δ(13C bone and δ(18O bone and the serial analysis of structural carbonate of molar tooth enamel (δ(13C enamel and δ(18O enamel. Mochica camelids were bred in the low and/or middle valleys, unlike their modern counterparts, who are restricted to highland puna C3 pastures. Archaeological camelids had diverse and complex life histories, usually with substantial maize foddering. An ontogenetic switch in diet and possible residential mobility during the course of life were identified for some specimens. Although the inference of geographic origin from δ(18O bone and δ(18O enamel values was limited because of the lack of understanding of the influence of environmental and biological factors, tooth enamel analysis has great potential for exploring camelid herding practices and Andean pastoralism. Our study suggested that Mochica herders adapted their practices to the difficult lowland environment and that herding practices were varied and not restricted to breeding at higher altitudes. The role of maize in different aspects of the economic

Yöntem: Çalışmada 2007-2015 yılları arasındaki gemi kayıtları incelenmiş ve tablo 3’de bulunan veriler elde edilmiştir. Geminin 39000 saatlik ana makine piston ve silindir bakım saatleri tablosu oluşturulmuştur. Bulgular: Uygun yakıt ve silindir yağlama yağı ile ilgili bakım sonrası uygun yağ miktarının tespiti yapılmıştır. Değişken kükürt oranlarına göre ayarlanabilen silindir yağlayıcıları (cylinder oil lubricator için kükürt oranı ve yüke göre veriler girilerek Excel tabanlı yağ miktarı hesaplama uygulaması modellenmiştir. Sonuç: Yapılan çalışma sayesinde başka tonaj ve tipteki makinelere aynı model uygulanarak makine bakım geçmişi çıkarılarak eksiklikler saptanabilir veya hazırlıklar yapılabilir. Örneğin 15000-19999 çalışma saati aralığında 16 kez piston bakımı yapıldığına göre layner değişiminden sonraki ikinci 20000 saatlik dilimde 35000-40000 saatlik dilimde piston ve layner değişimlerinin olacağı önceden tespit edilerek gerekli yedek malzeme erken tedarik edilerek zamandan kazanılmış olur. Bu sayede daha büyük arızaların önü kesilmiş olur. Şirket ve gemi arasında planlı bakım sistemi daha verimli hale getirilmiş olur. Bu kapsamda yapılan çalışma ile literatüre gerçek bir uygulamadan yola çıkılarak ilerideki çalışmalar için başlangıç olması hedeflenmiştir.

Ethnographic interviews, narratives, and "contextualized semantic analysis" reveal the lived experience of childhood respiratory diseases among 22 urban mangrove dwellers. Informants speak an "eco-idiom of respiratory distress" based on a popular "eco-logic", reflecting the harsh reality of "living in dampness". "Higher-up" residents legitimize their feelings of superiority by stigmatizing "lowlanders" as taboo, diseased (with porcine cysticercosis, swine flu "filthy pigs, stuck in the muck" (atolados na lama. Animalizing inhabitants' identities demotes them to nonpersons. Besides infections, children suffer social stigma, ostracism, and barriers for accessing care.

    Global carbon cycle mainly depends on the soil organic matter (SOM). Some reducction of climatic impact techiques are related to the increase of the soil organic carbon (SOC) contents in order to elevate atmospherical carbon inputs. Kinetic mechanisms of the SOC are differents due to the complex interation between biological, physical and chemical processes in the soil. For a full understanding of the SOM contribution to the carbon cycle in the soil, the SOC contents should be addressed. The vicuna (Vicugna vicugna) is an endangered species which belongs to camelid family. Its natural habitat is located in highland grasses in the Andes Montain Range, above 4,000 m.a.s.l. In Bolivia the vicuna is distributed around some andean regions such as Apolobamba. It is a protected area located in the Northwest of Bolivia where native inhabitants carry out a sustainable management of the vicuna. This activity is considered within a programme to improve economical conditions in the area. The vicuna lives in the same habitat than other cattle camelid like alpaca (Lama pacos). The soil is an essential natural resource in the vicuna development and the biodiversity conservation due to its role to support the native vegetation in Apolobamba. The objectives of this research were: (i) the quantification of SOC contents, (ii) the study of the SOC quality and (iii) the determination of the soil degradation degree in some zones in Apolobamba. Eight zones or census places, separated areas with geographic accidents, with different vicuna and alpaca densities were selected: Ulla-Ulla and Killu (low density), Ucha-Ucha and Wakampata (medium density), Sucondori and Caballchiñuni (high density) and Puyo-Puyo and Japu (very high density). One soil profile was taken and three sampling plots were determined in each zone. Three sampling points were selected in each plot and surface (0-5 cm) and subsurface samples (5-15 cm) were collected. Total carbon, total organic carbon (TOC) and water

    Hepatic encephalopathy has been listed as a differential for llamas displaying neurologic signs, but it has not been histopathologically described. This report details the neurologic histopathologic findings associated with 3 cases of hepatic lipidosis with concurrent neurologic signs and compares them to 3 cases of hepatic lipidosis in the absence of neurologic signs and 3 cases without hepatic lipidosis. Brain from all 3 llamas displaying neurologic signs contained Alzheimer type II cells, which were not detected in either subset of llamas without neurologic signs. Astrocytic immunohistochemical staining intensity for glial fibrillary acid protein was decreased in llamas with neurologic signs as compared to 2 of 3 llamas with hepatic lipidosis and without neurologic signs and to 2 of 3 llamas without hepatic lipidosis. Immunohistochemical staining for S100 did not vary between groups. These findings suggest that hepatic encephalopathy may be associated with hepatic lipidosis in llamas.

    Full Text Available Samples from 9 llamas (28 through 36 weeks of gestation were collected and fixed in 4% buffered paraformaldehyde (light microscopy and in 2.5% buffered glutaraldehyde (transmission and scanning electron microscopy. The material was processed in paraplast and slides (5mm were stained with HE, PAS, Masson-Trichrome, acid phosphatase and Perl's. The uteroferrin was immunolocalized. The results show that llama placenta is chorioallantoic, diffuse, folded and epitheliochorial, and the fetus is covered with an epidermal membrane. The trophoblast cells have variable morphology: cubic, rounded and triangular cells, with cytoplasm containing PAS-positive granules. Binucleated cells with large cytoplasm and rounded nuclei, as well as giant trophoblastic cells with multiple nuclei were also observed. Numerous blood vessels were observed beneath the cells of the uterine epithelium and around the chorionic subdivided branches. Glandular activity was shown by PAS, Perl's, and acid phosphatase positive reactions in the cytoplasm and glandular lumen, and by immunolocalization of the uteroferrin in the glandular epithelium. The uterine glands open in spaces formed by the areoles, which are filled by PAS-positive material. The llama fetus was covered by the epidermal membrane, composed of stratified epithelium, with up to seven layers of mono-, bi- or trinucleated cells. The high level of maternal and fetal vascularization surfaces indicates an intense exchange of substances across both surfaces. The metabolic activity shown in the uterine glands suggests an adaptation of the gestation to the high altitudes of the natural habitat of this species.Fragmentos da placenta de 9 animais (28-36 semanas de gestação, provenientes do Instituto Veterinario de Investigaciones Tropicales y de Altura (IVITA, Cusco-Peru, e da Universidad del Altiplano (UNA, Puno-Peru, foram colhidos e fixados em paraformoldeído 4% em PBS para microscopia de luz e em glutaraldeido em 2,5% PBS para microscopia eletrônica de transmissão e de varredura. O material incluido em paraplast cortado com 5 mm foi processado para HE, PAS, Tricrômio de Masson, fosfatase ácida e Perl's e para imuno-histoquimica da uteroferrina. Os resultados mostraram que a placenta da lhama é corialantóide, difusa, pregueada e epiteliocorial e o feto está recoberto pela membrana epidermal. O trofoblasto possui morfologia variada: células cúbicas, arredondadas ou triangulares, com citoplasma contendo grânulos PAS+. Células binucleadas com citoplasma aumentado e núcleo arredondado e células trofoblásticas aumentados com múltiplos núcleos, também foram observadas. Grande quantidade de vasos sanguíneos foi observada entre as células do epitélio uterino e ao redor das projeções coriônicas, as quais estavam subdivididas. A atividade glandular foi demonstrada pelas reações de PAS, Perl's e fosfatase ácida positivas e pela imunolocalização da uteroferrina na luz e epitélio glandular. As glândulas uterinas abrem-se nos espaços formados pelas aréolas, as quais estavam preenchidas por material PAS+. Os fetos das lhamas estavam recobertos pela membrana epidermal, constituída por um epitélio estratificado composto por mais de 7 camadas de células mono, bi ou trinucleadas. A alta vascularização das superfícies materna e fetais indica intensa capacidade de trocas de substâncias entre as duas superfícies, e a atividade metabólica mostrada pelas glândulas uterinas sugere adaptação da gestação às altitudes elevadas do habitat natural desta espécie.

    The seroprevalence of pestivirus infections in small ruminants and new world camelids in Switzerland was determined. In 5'059 sera of sheep from 382 herds, 503 sera of goats from 54 herds and 109 sera of alpacas and lamas from 53 herds, population prevalences of 16.1% (sheep), 25.4% (goats) and 4.6% (new world camelids), respectively, were found. In order to determine the source of infection, the serological reactions were further characterized by cross-neutralization against two pestiviruses representing the genotypes BVDV (Bovine Virus Diarrhea Virus)-1 and BDV (Border Disease Virus)-1. Based on the ratio of respective antibody titres, 56.1% of the infections in sheep were induced by a BDV-1, 12.9% by a BVDV-1 and 31.0% by an unresolved pestivirus. In goats, the corresponding proportions were 23.4%, 10.2% and 66.4%, respectively. In Alpacas and Lamas, the source of infection of 1 animal was BDV-1 and that of 4 seropositive animals remained unresolved. In view of the phylogenetic relationship between pestiviruses, the unresolved source of infection is most probably attributable to other pestivirus genotypes circulating in small ruminants and new world camelids. Due to the predominance of pestiviral genotypes other than BVDV-1, the risk of transmission of BVDV from persistently infected small ruminants and new world camelids to cattle appears to be moderate, apart from close direct contact in mixed animal husbandry, communal pasturing and grazing in the Alps.

    Most small ruminant farms in tropical climates are plagued by Haemonchus contortus, a hematophagous, abomasal parasite. Heavy burdens of this parasite can cause anemia, hypoproteinemia, weight loss, and mortality in susceptible animals. Haemonchus contortus is becoming a major health concern in New World camelids as well, namely llamas (Llama glama) and alpacas (Vicugna pacos), yet little research has been conducted regarding its prevalence or pathology in these species. Herein, we present a retrospective review of llamas and alpacas that were admitted to The University of Georgia Veterinary Teaching Hospital and Athens Diagnostic Laboratory between the years 2002 and 2013. Antemortem fecal egg count (FEC) estimates performed on 30 alpacas were negatively correlated with hematocrit, hemoglobin, and red blood cell count. Total protein was not significantly correlated with FEC. On postmortem examination, 55 of 198 camelids, including 2 from the aforementioned antemortem review, were infected with H. contortus, with llamas (42.6%) having a significantly higher infection rate than alpacas (22.2%). In 15.7% of the total cases, the parasite was the major cause of death. Common gross lesions included peritoneal, thoracic, and pericardial effusions, visceral pallor, subcutaneous edema, and serous atrophy of fat. Histologic lesions included centrilobular hepatic necrosis, hepatic atrophy, lymphoplasmacytic inflammation of the mucosa of the third gastric compartment (C3), extramedullary hematopoiesis in both the liver and spleen, and the presence of nematodes in C3. Our study emphasizes the importance of H. contortus diagnosis and herd monitoring in New World camelids, particularly llamas. © 2016 The Author(s).

    Alzheimer's disease is characterised by a loss of cognitive function and behavioural problems as set out in the term "Behavioural and Psychological Symptoms of Dementia". These behavioural symptoms have heavy consequences for the patients and their families. A greater understanding of behavioural symptoms risk factors would allow better detection of those patients, a better understanding of crisis situations and better management of these patients. Some retrospective studies or simple observations suggested that personality could play a role in the occurrence of behavioural symptoms. Finally, performance in social cognition like facial recognition and perspective taking could be linked to certain personality traits and the subsequent risks of behavioural symptoms. We propose to clarify this through a prospective, multicentre, multidisciplinary study. Main Objective: -To assess the effect of personality and life events on the risk of developing behavioural symptoms. Secondary Objectives: -To evaluate, at the time of inclusion, the connection between personality and performance in social cognition tests; -To evaluate the correlation between performance in social cognition at inclusion and the risks of occurrence of behavioural symptoms; -To evaluate the correlation between regional cerebral atrophy, using brain Magnetic Resonance Imaging at baseline, and the risk of behavioural symptoms. Study type and Population: Prospective multicentre cohort study with 252 patients with Alzheimer's disease at prodromal or mild dementia stage. The inclusion period will be of 18 months and the patients will be followed during 18 months. The initial evaluation will include: a clinical and neuropsychological examination, collection of behavioural symptoms data (Neuropsychiatric-Inventory scale) and their risk factors, a personality study using both a dimensional (personality traits) and categorical approach, an inventory of life events, social cognition tests and an Magnetic Resonance Imaging. Patients will be followed every 6 months (clinical examination and collection of behavioural symptoms data and risk factors) during 18 months. This study aims at better identifying the patients with Alzheimer's disease at high risk of developing behavioural symptoms, to anticipate, detect and quickly treat these disorders and so, prevent serious consequences for the patient and his caregivers.

    Camelid immunoglobulin variable (IGV) regions were found homologous to their human counterparts; however, the germline V repertoires of camelid heavy and light chains are still incomplete and their therapeutic potential is only beginning to be appreciated. We therefore leveraged the publicly available HTG and WGS databases of Lama pacos and Camelus ferus to retrieve the germline repertoire of V genes using human IGV genes as reference. In addition, we amplified IGKV and IGLV genes to uncover the V germline repertoire of Lama glama and sequenced BAC clones covering part of the Lama pacos IGK and IGL loci. Our in silico analysis showed that camelid counterparts of all human IGKV and IGLV families and most IGHV families could be identified, based on canonical structure and sequence homology. Interestingly, this sequence homology seemed largely restricted to the Ig V genes and was far less apparent in other genes: 6 therapeutically relevant target genes differed significantly from their human orthologs. This contributed to efficient immunization of llamas with the human proteins CD70, MET, interleukin (IL)-1β and IL-6, resulting in large panels of functional antibodies. The in silico predicted human-homologous canonical folds of camelid-derived antibodies were confirmed by X-ray crystallography solving the structure of 2 selected camelid anti-CD70 and anti-MET antibodies. These antibodies showed identical fold combinations as found in the corresponding human germline V families, yielding binding site structures closely similar to those occurring in human antibodies. In conclusion, our results indicate that active immunization of camelids can be a powerful therapeutic antibody platform. PMID:26018625

    Treatment and outcome of camelids with long-bone fractures are described. Medical records (1998–2008) of camelids (n = 28) with long-bone fractures were reviewed for signalment, time to presentation, fracture type, method of repair, duration of hospitalization, and post-operative complications. Follow-up information was obtained via telephone interviews with owners. Mean age and weight at presentation were 3.4 years and 56.3 kg, respectively. Twenty-six fractures were treated with internal fixation (n = 11), external fixation (n = 10), combination of internal and external fixation (n = 3), amputation (n = 1), and external fixation followed by amputation (n = 1). Long-term follow-up information was obtained for 19 of the 26 animals. The post-operative complication rate was 23% and owner satisfaction was high. Animals with open fractures were more likely to experience complications. Internal fixation was associated with superior alignment and outcome. Internal fixation techniques should be recommended for camelids. PMID:23277645

    Full Text Available The aim of this study was to monitor the content of trace elements in the hair of South American camelids and to evaluate the effect of coat colour, species, age, and sex on their concentration in the hair. The samples were collected from 77 animals – 23 llamas (Llama guanicoe f. gllama and 54 alpacas (Llama guanicoe f. pacos during a spring health check. The concentrations of copper (Cu, zinc (Zn, and manganese (Mn were determined by Flame Atomic Absorption Spectrometry and selenium (Se by Hydride Generation Atomic Absorption Spectrometry. We found the following concentrations (mean ± standard deviation; mg/kg dry matter in the llama hair: Cu 9.70 ± 4.69; Zn 145.20 ± 21.07; Mn 12.49 ± 10.14; Se 0.25 ± 0.14. In alpaca hair we found the following concentrations: Cu 10.22 ± 2.90; Zn 129.81 ± 19.01; Mn 12.67 ± 13.85; Se 0.48 ± 0.24. We found a significant difference between llamas and alpacas in Zn and Se concentrations in the hair. From all the evaluated factors we found that coat colour had the highest effect on Mn and Se concentration. Dark haired animals had significantly higher concentrations of these trace elements than other coloured groups. The evaluation of the concentration of trace elements in the hair of llamas has a potential to be used for the evaluation of long-term status of trace elements in the body; however, it is necessary to continue with experimental work in this area. Our findings can serve as a pilot study for further works in this field.

    In late summer/early fall of 2013, 2 South American camelids from central Washington were diagnosed with fatal bluetongue viral disease, an event which is rarely reported. A 9-year-old intact male llama (Lama glama), with a 1-day history of anorexia, recumbency, and dyspnea before death. Abundant foam discharged from the mouth and nostrils, and the lungs were severely edematous on postmortem examination. Histologically, there was abundant intra-alveolar edema with fibrin. Hemorrhage and edema disrupted several other organs. Bluetongue viral RNA was detected by reverse transcription polymerase chain reaction (RT-PCR), and serotype 11 was identified by sequencing a segment of the VP2 outer capsid gene. Approximately 1 month later, at a site 150 miles north of the index case, a 2-year-old female alpaca with similar, acutely progressive clinical signs was reported. A postmortem examination was performed, and histologic lesions from the alpaca were similar to those of the llama, and again serotype 11 was detected by PCR. The occurrence of bluetongue viral infection and disease is described in the context of seasonal Bluetongue virus activity within the northwestern United States and southwestern Canada. © 2015 The Author(s).

    Full Text Available The objective of this research was to study the  influence  of host deprivation on the oviposition and physiological condition of Snellenius manilae Ashmead. The research was conducted at Laboratory of Bioecology of Parasitoid and Predator, Department of Plant Protection, Faculty of Agriculture, IPB. Ten parasitoids of the same age and cohort were used in this experiment. Deprivation of hosts were done for 1, 2, 3, 4, 5, 6 and 7 days at the beginning and toward the end of their life. All hosts were replaced every 24 hours. Result indicated that host deprivation affects the reproductive capacity of Snellenius manilae. Even though parasitoids were able to lay eggs even when they were deprived of hosts for seven consecutive days, the overall results of host deprivation experiment showed that the length and timing of deprivation period can affect reproductive capacity. Deprivation of hosts tends to increase the parasitism rate and the numbers of eggs laid upon their first encounter of hosts after the treatment. The difference is more pronounced on treatements that allowed parasitism to occur before the deprivation treatment. However, the overall results suggests that deprivation overall decrease the reproductive capacity of the parasitoid. The longevity of deprived individuals was also lengthened. Parasitoids that were given host before deprivation treatments tend to produced more eggs than those were not. These results showed that deprivation of hosts in the field may affect the effectiveness of parasitoids and the success of biological control.

    Full Text Available The tradition of illustrated writing and drawing was found in the old manuscripts of Indonesia. Some parts of those old manuscripts show unique illustrations depicting local identity of Nusantara. It is thought that the manuscript reflects societal culture of thinking as well as aesthetic achievement of visual art. The illustrations of those old Javanese manuscripts were well documented and represented in various visual styles, drawing methods, themes, and visualized objects; even though their visual concepts practically resembles to each other.  The presented paper discusses the visual character and styles of illustrations found in the old manuscripts of Java within the year of 1800-1920. The illustration in those old Javanese manuscripts shows continuous correlation to the visual style of the past era and the present. Thus, it emboldens the characteristics of Indonesian visual states. It reflects structured illustration and visual style as well as expressive symbols of the Javanese society. Illustration of the old Javanese manuscript in the year 1800-1920 showed some changes and uniqueness in its visuals, comprising interaction between animism in the Pre-Hinduism era, cultural paradigm of Hinduism-Budhism, Islamic beliefs, and Colonialism. Having observed the visual illustration in the old Javanese manuscripts, it can be deduced that their styles are characterized as decorative, naturalistic, realistic, simple, and deformed.

    Serrano-González Joseline

    2011-09-01

    Full Text Available Abstract Background Camelids and sharks possess a unique subclass of antibodies comprised of only heavy chains. The antigen binding fragments of these unique antibodies can be cloned and expressed as single domain antibodies (sdAbs. The ability of these small antigen-binding molecules to refold after heating to achieve their original structure, as well as their diminutive size, makes them attractive candidates for diagnostic assays. Results Here we describe the isolation of an sdAb against Staphyloccocus aureus enterotoxin B (SEB. The clone, A3, was found to have high affinity (Kd = 75 pM and good specificity for SEB, showing no cross reactivity to related molecules such as Staphylococcal enterotoxin A (SEA, Staphylococcal enterotoxin D (SED, and Shiga toxin. Most remarkably, this anti-SEB sdAb had an extremely high Tm of 85°C and an ability to refold after heating to 95°C. The sharp Tm determined by circular dichroism, was found to contrast with the gradual decrease observed in intrinsic fluorescence. We demonstrated the utility of this sdAb as a capture and detector molecule in Luminex based assays providing limits of detection (LODs of at least 64 pg/mL. Conclusion The anti-SEB sdAb A3 was found to have a high affinity and an extraordinarily high Tm and could still refold to recover activity after heat denaturation. This combination of heat resilience and strong, specific binding make this sdAb a good candidate for use in antibody-based toxin detection technologies.

    Thirty female dromedary camels were inseminated on a total of 50 occasions with 2-4 ml of fresh guanaco semen diluted with an equal volume of commercially available camel semen extender. Similarly, nine female guanacos were inseminated on 34 occasions with 4-6 ml of fresh, diluted camel semen. Only two of the dromedary females conceived; one aborted a female foetus on day 260 of gestation and the other gave birth to a stillborn female calf on day 365. Six conceptions occurred in the female guanacos. Two of these conceptuses, diagnosed by ultrasound, were resorbed between days 25 and 40 of gestation, one female foetus was aborted on day 291, another female foetus was aborted on day 302, and one female calf was stillborn on day 365 of gestation. The sixth foetus, a male, was born prematurely but alive after a 328-day gestation. It had a phenotypic appearance intermediate between that of a camel and a guanaco and its hybrid parentage was confirmed by the DNA fingerprinting of eight llama microsatellites. To our knowledge, this is the first viable hybrid ever to be produced between Old World and New World camelids, which have been reproductively isolated from one another for at least 11 million years. The preponderance of female hybrids is in accordance with Haldane's law. Histological examination of their ovaries revealed a failure of meiosis, with only an occasional abnormal oocyte surrounded by follicle cells. Although the diploid chromosone number of camels and guanacos is the same (2n = 74), sufficient genetic change has taken place to make the pairing of homologous chromosomes no longer possible.

    Hawaiian mo`olelo (stories, legends, literature), especially those recorded and written in Hawaiian language, function as a record of traditional and customary practices that are critically relevant to current scientific research. This is especially true of scientific studies measuring water quality parameters that might depend on land management practices. The following study aimed to use mo`olelo to integrate water-related research by two doctoral students from different disciplines, native Hawaiian studies and marine biology, from the University of Hawai`i at Mānoa. We compared the relationship between water quality, mo`olelo, and historical land usage at three sites. Two sites are in the urbanized Maunalua Bay, on the southern coast of Oahu. One site is in an undeveloped kuleana (property) in `Ioleka`a, on the windward side of Oahu. Nutrient concentrations along with other water quality parameters were measured in fresh water streams in `Ioleka`a and coastal areas, in Maunalua Bay, that receive inputs from subterranean groundwater discharge. Research on site-specific mo`olelo was conducted and an analysis made on the associative values pertaining to the gods as elements, their kinolau (body form), and the connections with the water quality. Based on our findings, we created a lexicon of Hawaiian language science terms that are not solely transliterated but take into account the processes (scientific and Hawaiian) involved in the terms' definitions. This project provided a deeper understanding of the intricacies in relating water quality-based science and traditional customary and contemporary practices (TCCP). To conclude, we reflected on lesson learned, challenges, and future directions for similar interdisciplinary projects.

    Full Text Available The high fibrolytic activity and large biomass of strictly-anaerobic bacteria that inhabit the rumen makes them primarily responsible for the degradation of the forage consumed by ruminants. Llamas feed mainly on low quality fibrous roughages that are digested by an active and diverse microflora. The products of this fermentation are volatile fatty acids and microbial biomass, which will be used by the animals. The aim of this study was to detect the three major fiber-digesting anaerobic bacteria in the forestomach contents of llamas by PCR. In this study, we detected Ruminococcus albus, Ruminococcus flavefaciens and Fibrobacter succinogenes in the forestomach contents of eight native llamas from Argentina.

    2009-09-01

    Full Text Available The objective of this study was to evaluate the results of osteometric analyses applied to camelid bones samples from Moche sites (I and VII AD located on the north coast of Peru. The bones analyzed in this study correspond to first phalanges from two Moche archaeological sites (Cerro Chepén and Moche Urban Zone. Discriminant analysis was conducted on a sample of 44 first phalanges, taking into account five measurments in each bone. The results showed the identification in both sites of two species of domestic camelids, Lama glama “llama” and Lama pacos“alpaca.” The interpretation of the results is discussed by explaining a model of geographic or vicariant speciation of camelids that inhabited the coast of Peru during Moche times. This model takes into account that in this environment currently camelids are not breed, as well as genetics and evolutionary factors in the new domestic form, the effect of Bergmann’s Rule, and new grasses in the morphology of this new form of domestic camelid, ,which lived in the region at the time of Moche.

    We present high sensitivity (σP ≃ 0.6 mJy) polarimetric observations in seven bands, from 2.1 to 38 GHz, of a complete sample of 104 compact extragalactic radio sources brighter than 200 mJy at 20 GHz. Polarization measurements in six bands, in the range 5.5-38 GHz, for 53 of these objects were reported by Galluzzi et al. We have added new measurements in the same six bands for another 51 sources and measurements at 2.1 GHz for the full sample of 104 sources. Also, the previous measurements at 18, 24, 33, and 38 GHz were re-calibrated using the updated model for the flux density absolute calibrator, PKS1934-638, not available for the earlier analysis. The observations, carried out with the Australia Telescope Compact Array, achieved a 90 per cent detection rate (at 5σ) in polarization. 89 of our sources have a counterpart in the 72-231 MHz GLEAM (GaLactic and Extragalactic All-sky Murchison Widefield Array) survey, providing an unparalleled spectral coverage of 2.7 decades of frequency for these sources. While the total intensity data from 5.5 to 38 GHz could be interpreted in terms of single component emission, a joint analysis of more extended total intensity spectra presented here, and of the polarization spectra, reveals that over 90 per cent of our sources show clear indications of at least two emission components. We interpret this as an evidence of recurrent activity. Our high sensitivity polarimetry has allowed a 5σ detection of the weak circular polarization for ˜ 38 per cent of the data set, and a deeper estimate of 20 GHz polarization source counts than has been possible so far.

    Full Text Available Dry fractionation will produce a fraction of olein and stearin with different composition of high melting and low melting as well the distribution of triacylglycerol (TAG in the form of trisaturated (St3, disaturated (St2U and monosaturated (StU2. This research aimed to study the effect of critical cooling rate and crystallization temperature on the composition and profile of TAG changes as well the melting properties of the fractionated coconut oil products. Coconut oilwas heated at 70°C then cooledat differentcooling rate to reach various crystalization temperatures. The oil was then stirred at 15rpm and allowed to crystallize at different period of time, and finally fractionated by vacuum filtration using Whatman #40 paper. Fractionation temperatures were the same as crystalization temperatures. The results showed that the critical cooling rate was proportional to the solid-like to liquid-like ratio, the content of St3 and SFC profile of olein fraction but inversely proportional to the content of St2U and StU2 TAG. Interval crystallization temperature between 21.30 and 21.73 °C produced the S/L ratio, the content of St3 TAG and SFC profiles of olein fractions lower and the content of St2U and StU2 TAG higher than the temperature interval below or above it. Coconut oil fractionation more effective in higher crystallization temperature or lower critical cooling rate. In these cooling treatments, St3 TAG which has high melting pointwould be concentrated at stearin fraction, while St2U and StU2 TAG and MCTwould be at olein fraction. Therefore, it will increase melting properties of stearin fraction and decrease olein fraction.

    Full Text Available This study aimed to analyze the long exposure to Cadmium (Cd on the levels of calcium and phosphate bone white mice. This study uses a white rat bone exposed and unexposed Cd were 24 male rats were divided into 4 groups for 0, 2, 4 and 6 weeks. After the surgery and then measured levels of calcium and phosphate bone white mice. The results showed that there were significant differences in the levels of Ca between control and treatment groups. White rat bone Ca levels decreased respectively 118,067 mg/gram of bone; 87,267 mg/gram of bone; 39,667 mg/gram of bone and 13,067 mg/gram bone at weeks 0, 2, 4 and 6. The results of statistical tests performed by Kruskal-Wallis (p=0.000; p0.05, which means that exposure to Cd can not lower phosphate levels significantly due to the reciprocal relationship between Ca and P which resulted in secretion of parathyroid hormone so the bone does not release phosphate in the number of great. Thus concluded that exposure to heavy metals cadmium (Cd for 6 weeks can reduce bone calcium white mice, but have not been able to reduce levels of phosphate bone white mice significantly.

    The Peruibe Black mud is used in therapeutic treatments such as psoriasis, peripheral dermatitis, acne and seborrhoea, as well as in the treatment of myalgia, arthritis, rheumatism and non-articular processes. Likewise other medicinal clays, it may not be free from possible adverse health effects due to possible hazardous minerals leading to respiratory system occurrences and other effects, caused by the presence of toxic elements. Once used for therapeutic purposes, any given material should be fully characterized and thus samples of Peruibe black mud were analyzed to determine physical and chemical properties: moisture content, organic matter and loss on ignition; pH, particle size, cation exchange capacity and swelling index. The elemental composition was determined by Neutron Activation Analysis, Atomic Absorption Graphite Furnace and X-ray fluorescence; the mineralogical composition was determined by X-ray diffraction. Another tool widely used to evaluate the behavior of trace elements, in various environmental matrices, is the sequential extraction. Thus, a sequential extraction procedure was applied to fractionate the mud in specific geochemical forms and verify how and how much of the elements may be contained in it. Considering the several sequential extraction procedures, BCR-701 method (Community Bureau of Reference) was used since it is considered the most reproducible among them. A simple extraction with an artificial sweat was, also, applied in order to verify which components are potentially available for absorption by the patient skin during the topical treatment. The results indicated that the mud is basically composed by a silty-clay material, rich in organic matter and with good cation exchange capacity. There were no significant variations in mineralogy and elemental composition of both, in natura and mature mud forms. The analysis by sequential extraction and by simple extraction indicated that the elements possibly available in larger quantities to be absorbed by the skin during treatment are Ca, Mg, Mn and Na.

    Several North American trees are hypothesized to have lost their co-evolved seed disperser during the late-Pleistocene extinction and are therefore considered anachronistic. We tested this hypothesis for the American persimmon ( Diospyros virginiana ) by studying the effects of gut passage of proposed seed dispersers on seedling survival and growth, natural fruiting characteristics, and modern animal consumption patterns. We tested gut passage effects on persimmon seeds using three native living species, the raccoon ( Procyon lotor ), Virginia opossum ( Didelphis virginiana ), and coyote ( Canis latrans ), and two Pleistocene analogs; the Asian elephant ( Elephas maximus ) and alpaca ( Vicugna pacos ). Persimmon seeds excreted by raccoons, coyotes, and elephants survived gut transit. Gut passage did not affect sprouting success, but did tend to decrease time to sprout and increase seedling quality. Under field conditions, persimmon fruits were palatable on the parent tree and on the ground for an equal duration, but most fruits were consumed on the ground. Seven vertebrate species fed upon persimmon fruits, with the white-tailed deer ( Odocoileus virginianus )-a species not capable of dispersing persimmon seeds-comprising over 90% of detections. Conversely, potential living seed dispersers were rarely detected. Our results suggest the American persimmon evolved to attract a variety of seed dispersers and thus is not anachronistic. However, human-induced changes in mammal communities could be affecting successful seed dispersal. We argue that changes in the relative abundance of mammals during the Anthropocene may be modifying seed dispersal patterns, leading to potential changes in forest community composition.

    Full Text Available Abstract Background The family Camelidae that evolved in North America during the Eocene survived with two distinct tribes, Camelini and Lamini. To investigate the evolutionary relationship between them and to further understand the evolutionary history of this family, we determined the complete mitochondrial genome sequence of the wild two-humped camel (Camelus bactrianus ferus, the only wild survivor of the Old World camel. Results The mitochondrial genome sequence (16,680 bp from C. bactrianus ferus contains 13 protein-coding, two rRNA, and 22 tRNA genes as well as a typical control region; this basic structure is shared by all metazoan mitochondrial genomes. Its protein-coding region exhibits codon usage common to all mammals and possesses the three cryptic stop codons shared by all vertebrates. C. bactrianus ferus together with the rest of mammalian species do not share a triplet nucleotide insertion (GCC that encodes a proline residue found only in the nd1 gene of the New World camelid Lama pacos. This lineage-specific insertion in the L. pacos mtDNA occurred after the split between the Old and New World camelids suggests that it may have functional implication since a proline insertion in a protein backbone usually alters protein conformation significantly, and nd1 gene has not been seen as polymorphic as the rest of ND family genes among camelids. Our phylogenetic study based on complete mitochondrial genomes excluding the control region suggested that the divergence of the two tribes may occur in the early Miocene; it is much earlier than what was deduced from the fossil record (11 million years. An evolutionary history reconstructed for the family Camelidae based on cytb sequences suggested that the split of bactrian camel and dromedary may have occurred in North America before the tribe Camelini migrated from North America to Asia. Conclusion Molecular clock analysis of complete mitochondrial genomes from C. bactrianus ferus and L

    Full Text Available Native Hawaiian children have the highest prevalence rate of asthma among all ethnicities in the State of Hawai‘i. Literature is limited regarding native Hawaiian parents’ perception and experience caring for their children with asthma. The purpose of this study is to explore contemporary native Hawaiian parents’ perspective and experience of caring for their children with asthma in the context of uncertainty. We applied a descriptive qualitative approach by means of directed content analysis using focus groups. Directed content analysis applied Mishel’s Uncertainty in Illness Theory to guide data collection, organization, and analysis. We found that parents’ personal stories about their children to be rich and enlightening. Findings verified that native Hawaiian parents experience uncertainty regarding asthma care as commonly described in the literature. Contextual influences including indigenous worldview and cultural values affected native Hawaiian parents’ perceptions and experiences with conventional asthma care. Unique findings involved the etiology of asthma, features of social support (‘ohana, and differentiation between Western medicine and traditional healing practices. As nurses focus on supporting the family’s cultural values and preferences related to asthma care and alternative remedies, native Hawaiian parents’ care of their children with asthma will be strengthened.

    The objectives of the present study were to determine the effects of exogenous GnRH administered 7 days after breeding on the formation of an accessory corpus luteum (ACL), plasma progesterone (P 4 ) concentrations and pregnancy rates. Adult females (n = 71) having a follicle ≥ 7 mm in diameter in the ovary were naturally mated (Day 0). On Day 7, ultrasonic examination was performed to confirm the occurrence of ovulation as evidenced by presence of an induced corpus luteum (ICL). Females with an ICL plus a dominant follicle ≥ 7 mm (n = 56) were treated with saline solution (SS, n = 29) or GnRH analogue (n = 27). On Day 14, the formation of an ACL was observed by ultrasonography. Blood samples were collected on Days 7 and 14 to quantify plasma P 4 concentrations. On Day 14, 21 of 27 (77.8%) females in the GnRH group developed an ACL, whereas females in the SS group did not. Progesterone concentrations on Day 7 and 14 in those llamas diagnosed as pregnant on Day 30 were not different (P > 0.05) between groups. In addition, P 4 concentration was similar for GnRH-treated females having two CL to those with a single CL. Pregnancy rates were similar (P > 0.05) between SS and GnRH groups (55.2% compared with 74.1% respectively) and the pregnancy rate for the GnRH group was not affected (P > 0.05) by the number of CL observed at Day 14 (66.6% and 75.6% for females with one and two CL respectively). In conclusion, GnRH administration on Day 7 after breeding leads to ACL formation; however, neither the plasma P 4 concentration nor pregnancy rate was affected by having an ACL.

    The mean retention times (MRT) of solute or particles in the gastrointestinal tract and the forestomach (FS) are crucial determinants of digestive physiology in herbivores. Besides ruminants, camelids are the only herbivores that have evolved rumination as an obligatory physiological process consisting of repeated mastication of large food particles, which requires a particle sorting mechanism in the FS. Differences between camelids and ruminants have hardly been investigated so far. In this study we measured MRTs of solute and differently sized particles (2, 10, and 20 mm) and the ratio of large-to-small particle MRT, i.e. the selectivity factors (SF(10/2mm), SF(20/2mm), SF(20/10mm)), in three camelid species: alpacas (Vicugna pacos), llamas (Llama glama), and Bactrian camels (Camelus bactrianus). The camelid data were compared with literature data from ruminants and non-ruminant foregut fermenters (NRFF). Camelids and ruminants both had higher SF(10/2mm)FS than NRFF, suggesting convergence in the function of the FS sorting mechanism in contrast to NRFF, in which such a sorting mechanism is absent. The SF(20/10mm)FS did not differ between ruminants and camelids, indicating that there is a particle size threshold of about 1 cm in both suborders above which particle retention is not increased. Camelids did not differ from ruminants in MRT(2mm)FS, MRTsoluteFS, and the ratio MRT(2mm)FS/MRTsoluteFS, but they were more similar to 'cattle-' than to 'moose-type' ruminants. Camelids had higher SF(10/2mm)FS and higher SF(20/2mm)FS than ruminants, indicating a potentially slower particle sorting in camelids than in ruminants, with larger particles being retained longer in relation to small particles.

    The susceptibility of camelids for infectious agents which may result in severe economic losses or which are strictly regulated for epidemiological reasons in farm animals potentially causes a mutual risk of transmission. This study aimed to investigate the presence of antibodies against bovine herpesvirus 1 (BHV-1), bluetongue virus (BTV) and bovine viral diarrhoea virus (BVDV) as well as the presence of pestivirus antigen in new world camelids in Central Germany. Therefore 107 serum samples from 93 alpacas and lamas from this region which had been obtained from 2007 to 2009 were examined using ELISA, serum neutralisation test, RT-PCR and a pestivirus specific gene probe. All sample were negative for BHV-1 antibodies. Antibodies against BVDV-1 could be detected in four animals, titres reaching from 1:64 to > 1:256. One animal was positive for BTV antibodies in the year 2008. This animal had been tested negative for BTV antibodies in 2007. It can be concluded that up to now, these viruses seem to be of minor importance as pathogens in new world camelids in Central Germany. Therefore the risk of infection originating from new world camelids for production animals could be considered to be rather low in this region at the moment. However, it must be taken into consideration that these animals due to lack of antibodies are fully susceptible in case of occurrence of one of these viruses. For maintenance and improvement of the present status, general hygienic precautions should be applied; direct and indirect contact between animals from different herds must be avoided and virological diagnostic and quarantine should be required trading these animals.

    Methane emissions from ruminant livestock have been intensively studied in order to reduce contribution to the greenhouse effect. Ruminants were found to produce more enteric methane than other mammalian herbivores. As camelids share some features of their digestive anatomy and physiology with ruminants, it has been proposed that they produce similar amounts of methane per unit of body mass. This is of special relevance for countrywide greenhouse gas budgets of countries that harbor large populations of camelids like Australia. However, hardly any quantitative methane emission measurements have been performed in camelids. In order to fill this gap, we carried out respiration chamber measurements with three camelid species (Vicugna pacos, Lama glama, Camelus bactrianus; n = 16 in total), all kept on a diet consisting of food produced from alfalfa only. The camelids produced less methane expressed on the basis of body mass (0.32±0.11 L kg−1 d−1) when compared to literature data on domestic ruminants fed on roughage diets (0.58±0.16 L kg−1 d−1). However, there was no significant difference between the two suborders when methane emission was expressed on the basis of digestible neutral detergent fiber intake (92.7±33.9 L kg−1 in camelids vs. 86.2±12.1 L kg−1 in ruminants). This implies that the pathways of methanogenesis forming part of the microbial digestion of fiber in the foregut are similar between the groups, and that the lower methane emission of camelids can be explained by their generally lower relative food intake. Our results suggest that the methane emission of Australia's feral camels corresponds only to 1 to 2% of the methane amount produced by the countries' domestic ruminants and that calculations of greenhouse gas budgets of countries with large camelid populations based on equations developed for ruminants are generally overestimating the actual levels.

    Continuous measurement of the end-expiratory partial pressure of carbon dioxide (PETCO2) during anaesthesia has been proposed for non-invasive monitoring of arterial PCO2 (PaCO2). The values and the stability of the difference (PaCO2-PETCO2) during anaesthesia were studied for two ventilatory settings in eight children with healthy lungs and normal cardiac function undergoing minor surgery. PaCO2 values were all within a physiological range (30.2-43.6 mmHg). PaCO2-PETCO2 values ranged from 0.2 to 9.9 mmHg. With either mode of ventilation, there was no significant variation in PaCO2-PETCO2. It is concluded that estimation of PaCO2 was reliable during anaesthesia when haemodynamic and ventilatory states were stable, but a first determination of the PaCO2-PETCO2 gradient remained necessary for each child.

    Red mud is a by-product of the alkaline extraction of aluminum from the bauxite and represents a renewed environmental problem due the significant annual throughput by the plants. In the present work, the pozzolanic properties of Brazilian red mud fired at 600, 700, 800 and 900 deg C were investigated by monitoring lime consumption using DTA analysis and Brazilian standard methodology NBR 5772 (1992). Products and kinetics of hydration were determined in cement pastes produced with 5 and 15% red mud using x-ray diffraction and DTA analysis. Compressive strength and capillary absorption tests were realized on mortars constituted by 5, 10 and 15% red mud in replacement of cement. When calcined at 600 deg C, the red mud develops good pozzolanic properties, and the compressive strength of mortars produced with this waste meet values in accordance with regulatory standard. These results shown than red mud can be used, in partial replacement of cement, as new construction material to produce sustainable mortars with low environmental impact. (author)

Transgenic Arabidopsis plants harboring genetic constructs from which beta-glucuronidase (GUS) expression was driven by the full-length (pACO1:GUS, pACO2:GUS) or truncated (pACO1-1.2:GUS, pACO2-1.2:GUS) loblolly pine ACC oxidase gene promoters displayed distinctive patterns of expression for the different promoter constructs. Both full-length promoter constructs, but not those using truncated promoters, responded to indole-3-acetic acid (IAA) and wounding. Both pACO1:GUS and pACO1-1.2:GUS responded to pathogen attack, while neither version of the pACO2 promoter responded to infection. In the inflorescence stalks, the full-length pACO1 promoter construct, but not the truncated pACO1-1.2:GUS or either pACO2 construct, responded to bending stress. When flowering transgenic Arabidopsis plants were placed in a horizontal position for 48 h, expression from pACO2:GUS, but not the other constructs, was induced on the underside of shoots undergoing gravitropic reorientation. The expression pattern for the pACO2:GUS construct in transgenic Arabidopsis was consistent with what might be expected for a gene promoter involved in the compression wood response in loblolly pine. Although near complete sequence identity between PtACO1 and PtACO2 transcripts prevented quantitation of specific gene products, the promoter expression analyses presented in this study provide strong evidence that the two ACC oxidase genes are likely differentially expressed and responded to different external stimuli in pine. These results are discussed with respect to the potential functional differences between these two genes in loblolly pine.

    This paper presents a new process algebra, called PACoR, for real-time systems which deals with resource- constrained timed behavior as an improved version of the ACSR algebra. We define PACoR as a Process Algebra of Communicating Resources which allows to explicitly express preemptiveness......, urgentness and resource usage over a dense-time model. The semantic interpretation of PACoR is defined in the form of a timed transition system expressing the timed behavior and dynamic creation of processes. We define a translation of PACoR systems to Parameterized Stopwatch Automata (PSA). The translation...

    It has been nearly 30 years since the first imported llamas and alpacas have been commercially raised in the United States. Nutritional requirements for these animals have not been well understood and most feeding practices were based on extrapolated and experiential information. Only recently has a National Research Council committee reviewed the available published information relative to nutrient requirements of llamas and alpacas. This article summarizes current nutrient requirement recommendations and provides some practical feeding recommendations and methods to assess nutritional status.

    To describe a cranial arthroscopic approach to the stifle of South American camelids and to report our clinical experience with camelid stifle arthroscopy. Experimental study and retrospective case series. (1) Cadaveric alpaca hindlimbs (n = 18; 9 alpacas); (2) 1 alpaca and 1 llama Polymethylmethacrylate joint casts (n = 2) were made to define stifle joint dimensions. Cadaveric stifle joints (n = 16) were evaluated arthroscopically to determine arthroscopic portal locations, describe the intraarticular anatomy, and report potential complications. An alpaca and a llama with stifle joint disease had diagnostic arthroscopy. Successful entry into the stifle joint was achieved in 16 cadaver limbs. Observed structures were: the suprapatellar pouch, articular surface of the patella, femoral trochlear ridges and groove, cranial aspect of the femoral condyles (n = 16); distal aspect of the cranial and proximal aspect of the caudal cruciate ligaments (14); and cranial aspects of the medial and lateral menisci (11), and cranial meniscotibial and intermeniscal ligaments (8). Stifle arthroscopy allowed for joint evaluation and removal of osteochondral fragments in 1 alpaca and 1 llama with naturally occurring stifle disease. Complications of cadaver or live procedures included minor cartilage scoring (3 stifles) and subcutaneous periarticular fluid accumulation (8 stifles). Arthroscopy provides a safe approach for diagnosis and treatment of stifle lesions in South American camelids. Copyright 2012 by The American College of Veterinary Surgeons.

    The objective of this work was to evaluate the performance of a Co/Nb{sub 2}O{sub 5} catalyst in the Fischer-Tropsch Synthesis (FTS) in an agitated slurry reactor, using a methodology and reaction unit developed by the authors. Besides this, an evaluation of the reaction kinetic parameters, from the literature, was accomplished. The catalyst was prepared by the homogeneous precipitation method to obtain a cobalt content of 10 wt%. The reactions were accomplished, after ex-situ reduction, at 500 deg C, of 20 g of 10% Co/Nb{sub 2}O{sub 5} catalyst, in a 500 mL slurry reactor, loaded with 150 g of octacosane solvent (C{sub 28}H{sub 58}). The reaction temperature was varied from 180 to 220 deg C and the initial reaction mixture flow rate from 20 to 60 mL/min. The used reaction pressure was 20 bar. The selectivities were calculated by gaseous effluent chromatographic analysis, relating these effluent molar fractions with the slurry composition by an asymmetric model of the liquid - vapor equilibrium. An evaluation of the carbon chain growth probability parameter ({alpha}) was accomplished using the Anderson-Schulz-Flory products distribution model. The parameters of both kinetic models, with a possible reaction mechanism, were estimated by non linear regression analysis. The obtained results showed that the 10%Co/Nb{sub 2}O{sub 5} catalyst presented high stability within few hours of reaction, little selectivity for methane and CO{sub 2}, and high selectivity for C{sub 5+}, specially for gasoline (C{sub 5} - C{sub 11}) and diesel (C{sub 12} - C{sub 20}). The {alpha} calculated values were all grater than 0.75. The estimated parameters for both kinetic models were slightly smaller than the others cobalt catalysts parameters, from the literature. This models adjustment to the experimental data was satisfactory, showing correlation coefficients grater than 0.97. (author)

  2. William Wordsworth's 'Double Awareness' of Memory in Virginia Woolf's Mrs Dalloway = William Wordsworth'un 'Hatıranın Çift Yönlü Algılaması' Kavramının Virgina Woolf'un Mrs Dalloway Adlı Romanındaki Kullanımı

    Full Text Available This article deals with Romanticism in modernist British writer Virginia Woolf's novel, Mrs Dalloway. Although her works are experimental and new, they are part of a wider and developing perspective in the historical process of literary tradition, so that they cannot be viewed as completely breaking away from literary tradition, but rather as a reworking and redevelopment in its evolution. In her reworking of the traditional novel, this paper may suggest that Woolf made it "new" by returning to the Romantics, particularly to Wordsworth. By this claim, this paper does not mean that Woolf copied Wordsworth exactly, but was profoundly and pervasively influenced by his aesthetic views, especially in relation to her understanding of life as "consciousness". By returning to the Romantics, Woolf develops her sense of "reality" as both fragmented and whole, and of the "self" as fragmented but desiring and imagining unity. Hence she not only strove to construct a poetical or lyrical novel to express that contradictory view but also used her fiction to explore the mystery of the subjective consciousness as the dominant modernist view. In order to express her perception of modernist identity, Woolf used memory as a device in Mrs Dalloway and thus developed a new way of narration as well as a new view of human identity. By means of this new method, she left the objective narration of the traditional novel, and thus meaning or the view of identity in Woolf's late fiction is not static but undecided, unfinished and mysterious.

    Tuberculosis (TB) in South American camelids (SAC) is caused by Mycobacterium bovis or Mycobacterium microti. Two serological methods, rapid testing (RT) and the dual-path platform (DPP) assay, were evaluated using naturally infected SAC. The study population included 156 alpacas and 175 llamas in Great Britain, Switzerland, and the United States. TB due to M. bovis (n = 44) or M. microti (n = 8) in 35 alpacas and 17 llamas was diagnosed by gross pathology examination and culture. Control animals were from herds with no TB history. The RT and the DPP assay showed sensitivities of 71% and 74%, respectively, for alpacas, while the sensitivity for llamas was 77% for both assays. The specificity of the DPP assay (98%) was higher than that of RT (94%) for llamas; the specificities of the two assays were identical (98%) for alpacas. When the two antibody tests were combined, the parallel-testing interpretation (applied when either assay produced a positive result) enhanced the sensitivities of antibody detection to 89% for alpacas and 88% for llamas but at the cost of lower specificities (97% and 93%, respectively), whereas the serial-testing interpretation (applied when both assays produced a positive result) maximized the specificity to 100% for both SAC species, although the sensitivities were 57% for alpacas and 65% for llamas. Over 95% of the animals with evidence of TB failed to produce skin test reactions, thus confirming concerns about the validity of this method for testing SAC. The findings suggest that serological assays may offer a more accurate and practical alternative for antemortem detection of camelid TB. PMID:22012976

    Abstract The Mondzish languages were recently identified by Ziwo Lama (2012) as a coherent subgroup of Lolo-Burmese, and its most divergent branch as well. They are spoken primarily in Wenshan Prefecture, Yunnan Province, southwestern China. However, Lama (2012) only identified two lects, Maang and Mondzi, as Mondzish languages, and did not classify many other nearby lects that I am convinced are also Mondzish.

    2015-08-01

    A 12-week-old female dromedary camel (Camelus dromedarius) calf was evaluated because of acute (Streptococcus equi subsp zooepidemicus septicemia as the etiology for the polyserositis (ie, alpaca fever). Treatment with IV broad-spectrum antimicrobials, an NSAID, and pleural drainage was initiated. Clinical signs of pleuropneumonia, peritonitis, and systemic infection improved rapidly 24 hours after initiation of medical treatment. The calf was discharged from the hospital after 11 days, and antimicrobial treatment continued for 2 weeks after discharge. At follow-up approximately 4 weeks after hospital discharge (6 weeks after the initial examination), there were no clinical signs suggestive of relapse or any reported complications. S equi subsp zooepidemicus may cause polyserositis in Old World camelids (eg, dromedary camels) with signs similar to those seen in New World camelids (eg, alpaca and llama). The rapid response to medical treatment for the patient described suggested that S equi subsp zooepidemicus-induced polyserositis (alpaca fever) in dromedary camels may respond favorably to appropriate treatment. Reducing stress, reducing overcrowding, and separate housing of equids and camelids are suggested. Further studies are needed to better assess the epidemiology of alpaca fever in dromedary camels in North America.

    The objective of this study was to investigate the presence of Toxoplasma gondii- and Neospora caninum-specific antibodies in domestic South American camelids (SAC) (llamas and alpacas) from the Peruvian Andes through a cross-sectional study. A wide panel of serum samples collected from 1,845 llamas and 2,874 alpacas from the two main SAC production areas of Peru was selected. Immunofluorescence antibody technique was employed to detect and titrate specific anti-T. gondii and anti-N. caninum immunoglobulins G in serum samples. The association between T. gondii and N. caninum seroprevalence and the geographical origin (Central and South Peruvian Andes) was evaluated. Anti-T. gondii antibodies were found in 460 (24.9 %) llamas and 706 (24.6 %) alpacas, whereas anti-N. caninum antibodies were detected in 153 (8.3 %) llamas and 425 (14.8 %) alpacas. Toxoplasma gondii infection was strongly associated with the South Peruvian Andes where moderate climate conditions, larger human population, compared to the Central region, and the presence of wildlife definitive hosts could favor horizontal transmission to SAC. In contrast, N. caninum infection was not associated with the geographical region. These results indicate that T. gondii and N. caninum infections are highly and moderately widespread, respectively, in both species of domestic SAC studied in the sampled areas and appropriate control measures should be undertaken to reduce the prevalence of both parasitic infections.

    To measure and compare insulin secretion and sensitivity in healthy alpacas and llamas via glucose clamping techniques. 8 llamas and 8 alpacas. Hyperinsulinemic euglycemic clamping (HEC) and hyperglycemic clamping (HGC) were performed on each camelid in a crossover design with a minimum 48-hour washout period between clamping procedures. The HEC technique was performed to measure insulin sensitivity. Insulin was infused IV at 6 mU/min/kg for 4 hours, and an IV infusion of glucose was adjusted to maintain blood glucose concentration at 150 mg/dL. Concentrations of blood glucose and plasma insulin were determined throughout. The HGC technique was performed to assess insulin secretion in response to exogenous glucose infusion. An IV infusion of glucose was administered to maintain blood glucose concentration at 320 mg/dL for 3 hours, and concentrations of blood glucose and plasma insulin were determined throughout. Alpacas and llamas were not significantly different with respect to whole-body insulin sensitivity during HEC or in pancreatic β-cell response during HGC. Alpacas and llamas had markedly lower insulin sensitivity during HEC and markedly lower pancreatic β-cell response during HGC, in comparison with many other species. New World camelids had lower glucose-induced insulin secretion and marked insulin resistance in comparison with other species. This likely contributes to the disorders of fat and glucose metabolism that are common to camelids.

    In Switzerland, dicrocoeliasis is regarded as the most significant parasitic infection of llamas and alpacas. Fasciola hepatica infestation is also a problem but less common. The aim of the present retrospective study was to evaluate the lungs of New World camelids (NWCs) for evidence of arterial hypertension in association with liver changes due to liver fluke infestation. The lungs of 20 llamas and 20 alpacas with liver fluke infestation were histologically evaluated. The hematoxylin and eosin and van Gieson (VG)-elastica stains as well as immunohistology for the expression of α-smooth muscle actin (α-SMA) were used to visualize the structures of arterial walls. Parasitology of fecal matter (11 llamas and 17 alpacas) confirmed that most of these animals were infested with both Dicrocoelium dendriticum and other gastrointestinal parasites. In most cases (10/12 llamas, 4/6 alpacas), liver enzyme activity in serum was elevated. Histologically, arteries in the lungs of 9 of 20 llamas (45%) and 3 of 20 alpacas (15%) showed severe intimal and adventitial and slight to moderate medial thickening, which was confirmed with α-SMA and VG-elastica staining. All animals exhibited typical liver changes, such as fibrosis and biliary hyperplasia, in association with the presence of liver flukes. This study shows that liver flukes can induce proliferative changes in lung arteries in NWCs that resemble those seen with pulmonary arterial hypertension due to liver parasites in humans. However, the degree of liver fluke infestation was not correlated with the extent of liver damage, or with the amount of thoracic or abdominal effusion or pulmonary arterial changes. © The Author(s) 2015.

  9. Use of 'ideal' alveolar air equations and corrected end-tidal PCO2to estimate arterial PCO2and physiological dead space during exercise in patients with heart failure.

    2018-01-01

    Arterial CO 2 tension (PaCO 2 ) and physiological dead space (V D ) are not routinely measured during clinical cardiopulmonary exercise testing (CPET). Abnormal changes in PaCO 2 accompanied by increased V D directly contribute to impaired exercise ventilatory function in heart failure (HF). Because arterial catheterization is not standard practice during CPET, this study tested the construct validity of PaCO 2 and V D prediction models using 'ideal' alveolar air equations and basic ventilation and gas-exchangegas exchange measurements during CPET in HF. Forty-seven NYHA class II/III HF (LVEF=21±7%; age=55±9years; male=89%; BMI=28±5kg/m 2 ) performed step-wise cycle ergometry CPET to volitional fatigue. Breath-by-breath ventilation and gas exchange were measured continuously. Steady-state PaCO 2 was measured at rest and peak exercise via radial arterial catheterization. Criterion V D was calculated via 'ideal' alveolar equations, whereas PaCO 2 or V D models were based on end-tidal CO 2 tension (P ET CO 2 ), tidal volume (V T ), and/or weight. Criterion measurements of PaCO 2 (38±5 vs. 33±5mmHg, Pgas exchange and ventilatory responses demonstrate acceptable agreement with criterion measurements at peak exercise in HF patients. Routine assessment of PaCO 2 and V D can be used to improve interpretability of exercise ventilatory responses in HF. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    The relationship between end-tidal partial pressure of carbon dioxide (PETCO2), arterial partial pressure of carbon dioxide (PaCO2), and blood pH in isoflurane-anesthetized raptors was evaluated. PaCO2 and pH were determined in serial arterial samples from isoflurane anesthetized birds and compared with concurrent end-tidal partial pressure of carbon dioxide measured with a Microstream sidestream capnograph. Forty-eight paired samples, taken from 11 birds of prey (weighing 416-2,062 g), were used to determine correlations coefficients between PaCO2 and PETCO2, and between PETCO2 and pH. Limits of agreement between PaCO2 and PETCO2 also were calculated. Strong correlations were observed between PaCO2 and PETCO2 (r = 0.94; P 400 g and receiving manual positive ventilation with a Bain system. In our study, the linear relationship observed between the pH and the end-tidal partial pressure of carbon dioxide suggested that the monitoring of end-tidal partial pressure of carbon dioxide also can be useful to prevent respiratory acidosis.

    Respiratory monitoring is important after surgery to prevent pulmonary complications. End-tidal carbon dioxide (Petco(2)) measurement by capnometry is an indirect and noninvasive measurement of Pco(2) in blood and is accepted and recognized in critical care. To determine the correlation and level of agreement between Petco(2) and Paco(2) in spontaneously breathing children after cardiac surgery and to determine whether Petco(2) measured by using tidal volume (Vt-Petco(2)) or vital capacity (VC-Petco(2)) shows more or less significant correlation with Paco(2). Vt-Petco(2) and VC-Petco(2) by capnometry and Paco(2) by blood gas analysis were measured once a day after tracheal extubation. The determination coefficient and degree of bias between the methods were assessed in children with and without supplemental oxygen. A total of 172 Vt-Petco(2), VC-Petco(2), and Paco(2) values from 48 children were analyzed. The overall coefficients of determination were 0.84 (P breathing children, Vt-Petco(2) provided a more accurate estimate of Paco(2) than did VC-Petco(2), especially in children given little or no supplemental oxygen. The difference between the methods was significantly larger in the groups given 2 to 5 L of oxygen per minute.

    In critically ill patients, arterial blood gas analysis is the gold standard for evaluating systemic oxygenation and carbon dioxide partial pressure. A new miniaturized carbon dioxide tension Pco2-Spo2 single sensor (TOSCA, Linde Medical Sensors AG, Basel, Switzerland) continuously and noninvasively (transcutaneously) monitors both Paco2 and oxygen saturation by pulse oximetry (Spo2). The present study was designed to investigate the usability and the accuracy of this device in critically ill patients. Prospective clinical investigation. A 20-bed, university-affiliated, surgical intensive care unit. Patients admitted after major surgery, multiple trauma, or septic shock equipped with an arterial catheter. The heated (42 degrees C) sensor was fixed at the earlobe using an attachment clip. Transcutaneous Pco2 (TcPco2) measurements were correlated with Paco2 values (measured using a blood gas analyzer). In addition, the differences between Paco2 and TcPco2 values were evaluated using the method of Bland-Altman. We studied 55 patients, aged 18-80 (mean 57 +/- 15) yrs. A total of 417 paired measurements were compared. Correlation between TcPco2 and Paco2 was r = .86 (p TcPco2 slightly overestimating arterial carbon dioxide tension. Nineteen percent of the measured values were outside of the acceptable clinical range of agreement of +/-7.5 mm Hg. The present study suggests that Paco2 can be acceptably assessed by measuring TcPco2 using the TOSCA Pco2-Spo2 sensor.

    2018-03-01

    Recent updates to the GOLD guidelines emphasize the use of combination LABA and LAMA bronchodilators for patients with chronic obstructive pulmonary disease with persistent dyspnea despite monotherapy or frequent exacerbations despite LAMA monotherapy. There are several commercially available LABA/LAMA fixed dose combination inhalers, which are likely to become the principle therapy for many patients with COPD. In the last 4 years, there have been a number of large clinical trials evaluating the efficacy and safety of combined LAMA and LABA bronchodilators. LAMA/LABA fixed dose combination therapies have consistently demonstrated clinically significant improvements to airway obstruction, dyspnea, and quality of life whenever compared with placebo, and more modest improvements compared with bronchodilator monotherapies and combined bronchodilator/inhaled corticosteroid therapy. New guidelines emphasize combination bronchodilators as a mainstay of therapy for many patients with symptomatic COPD and there are several new combination bronchodilator therapies available to patients. It is important for physicians and patients to understand the range and degree of expected clinical effects and the safety profiles of these new medications.

    Cerebral blood flow (CBF), systemic hemodynamics, and arterial blood gases were measured during control conditions and during and after exposure to either 300 kPa O2 (group 1) or 300 kPa O2 with 2 kPa CO2 (group 2) in awake rats. The respiratory frequency fell with no change of arterial PCO2 (PaCO2) in group 1, but in group 2, respiratory frequency and PaCO2 increased linearly. The cardiac output (CO) and heart rate (HR) fell and systolic arterial pressure (SAP) rose independent of PACO2. O2 breathing caused CBF to fall by 30% in group 1, whereas CBF rose linearly with the PaCO2 increase and pH decline in group 2. Regional CBF (rCBF) fell in group 1, whereas rCBF rose gradually in all regions in group 2, but the responses varied similarly in both groups. Regional brain O2 supply was unaltered in most areas. However, the O2 supply was possibly reduced in the brain stem in group 1 but markedly increased in group 2. After decompression, HR and SAP were high, whereas CO returned to its control value. CBF and all rCBF levels remained markedly elevated in group 2. In group 1, CBF returned to control levels. By contrast, rCBF and O2 delivery to brain stem regions remained subnormal. In conclusion, the O2-induced changes in HR, CO, and SAP were not influenced by hypercapnia. CBF and rCBF fell despite unaltered PaCO2, whereas hypercapnia prevented these declines. An uneven effect of O2 was observed on rCBF, most pronounced in brain stem regions, independent of the PaCO2. There was a prolonged suppression of O2 supply to brain stem regions both during and after the exposure to O2 in the absence of CO2.

    To determine agreement between arterial partial pressures of carbon dioxide (PaCO(2)) and end-tidal partial pressures of carbon dioxide (PETCO(2)) measured with a nasal catheter in spontaneously breathing, critically ill dogs. Validation study. 26 client-owned dogs admitted to an intensive care unit for various conditions. PaCO(2) was measured with a commercial blood gas analyzer, and PETCO(2) was measured with a sidestream capnograph attached to a nasal catheter. Measurements were obtained twice (ie, with and without supplemental oxygen). Paired values were compared by means of the Pearson correlation method. Level of agreement was assessed by means of the Bland-Altman method. Mean difference between PaCO(2) and PETCO(2) when dogs did not receive supplemental oxygen (mean +/- SD, 3.95 +/- 4.92 mm Hg) was significantly lower than mean difference when dogs did receive supplemental oxygen (6.87 +/- 6.42 mm Hg). Mean difference in dogs with a condition affecting the respiratory system (8.55 +/- 5.43 mm Hg) was significantly higher than mean difference in dogs without respiratory tract disease (3.28 +/- 3.23 mm Hg). There was a significant linear correlation and good agreement between measured values of PaCO(2) and PETCO(2). Catheter size, ventilatory status, and outcome were not significantly associated with mean difference between PaCO(2) and PETCO(2). Results suggested that nasal capnography is a clinically relevant method of estimating PaCO(2) in spontaneously breathing, critically ill dogs, but that values should be interpreted with caution in dogs receiving supplemental oxygen and in dogs with conditions affecting the respiratory system.

    The harmful effect of hypocapnia on the neonatal brain emphasizes the importance of monitoring arterial carbon dioxide tension (PaCO2). Transcutaneous monitoring of carbon dioxide (tcPCO2) reduces the need for arterial blood sampling. Drawbacks are high electrode temperature causing risks of skin burning. The aim was to determine the accuracy and precision of tcPCO2 at reduced electrode temperature. Forty newborns (GA 24.9-41.7) were included. Two tc-monitors were applied (TCM4, Radiometer, Copenhagen). Arterial blood gas sampling and monitoring of tcPCO2-level at different electrode temperatures was done simultaneously (39°C, 40°C, 41°C, 42°C, 44°C). Difference of PaCO2 - tcPCO2 was expressed as a percentage of the mean. Mean PaCO2 was 5.8kPa [3,2; 7.9]. Bias (PaCO2 - tcPCO2) increased from 5% at 44°C to 17% at 39°C, but did not differ significantly between 41°C and 40°C. The precision of the tcPCO2 at each temperature ranged from +7-10%. After correction for the temperature-dependent overreading, we found increasing PaCO2 - tcPCO2 difference with increasing PaCO2, approx. 2% pr. kPa increase of CO(2). Only mild transient erythema was observed. A lower electrode temperature in tcPCO2-monitoring increases systematic overreading of the tc-electrode. However, in very preterm babies, monitoring at 40°C or 41°C is possible provided a bias correction of 12-15% is applied.

    Measurement of the arterial carbon dioxide (P(a)CO(2)) is an established part of the monitoring of mechanically ventilated patients. Other ways to get information about carbon dioxide in the patient are measurement of end-tidal carbon dioxide (P(ET)CO(2)) and transcutaneous carbon dioxide (PTCCO2......). Carbon dioxide in the blood and cerebral tissue has great influence on vasoactivity and thereby blood volume of the brain. We have found no studies on the correlation between P(ET)CO(2) or P(TC)CO(2), and P(a)CO(2) during hyperbaric oxygen therapy (HBOT)....

We analyzed a total of 16,446 patients who had been prescribed a LAMA between January 1, 2013 and December 31, 2013. The follow-up period, based on a centralized system of electronic prescription management, was extended until December 2014.Results: During 2013, the medication collected was 7.4%–10.7% higher than indicated by labeling. This was very similar for all LAMAs, irrespective of the patient’s sex, the molecule, the device, and the drug dosage. We did not observe seasonal variations in the consumption of LAMAs, nor did we detect differences between prescription drugs for once-daily (every 24 hours versus twice-daily (every 12 hours administration, between the different molecules, or between different types of inhalers for the same molecule. The results were similar in 2014.Conclusion: The principal conclusion of this study is that, in an area with a centralized management system of pharmacological prescriptions, adherence to treatment with LAMAs is very high, irrespective of the molecules or inhalation device. We did not find that patients who used twice-daily medication had a lower adherence. Keywords: COPD, treatment, adherence, LABAs, LAMAs, PDC, asthma

    This study aimed to investigate whether perioperative inhalations of long-acting beta-agonists (LABAs) or long-acting muscarinic antagonists (LAMAs) might decrease the incidence of postoperative complications in lung cancer patients with chronic obstructive pulmonary disease (COPD). We retrospectively analyzed 108 patients with COPD who underwent pulmonary resections for primary lung cancer at our hospital between January 2013 and January 2016 to determine the association between the incidence of postoperative complications (e.g., prolonged air leakage and pneumonia) and the use of LABAs or LAMAs. Thirty patients with COPD experienced postoperative complications (27.8%): Fourteen patients had prolonged air leakages (more than 7 days), ten patients developed pneumonia. The frequency of these postoperative pulmonary complications was significantly higher among the patients with COPD (24/108 cases, 22.2%), compared with the frequency among non-COPD patients (15/224 cases, 6.7%). Inhaled bronchodilators, such as LAMA or LABA, were prescribed for 34 of the 108 patients with COPD; the remaining 74 patients were not treated with bronchodilators. Pulmonary complications were significant lower among the LAMA or LABA users (3/34 cases, 8.8%) than among the untreated COPD patients (21/74 cases, 28.4%). For lung cancer patients with COPD, preoperative management using LABA or LAMA bronchodilators and smoking cessation can reduce the frequency of postoperative pulmonary complications after surgical lung resection. LAMA or LABA inhalation might be useful for not only perioperative care, but also for the long-term survival of COPD patients after surgery.

Although the efficacy of LAMAs and LABAs has been well established through randomized controlled trials (RCTs, questions remain regarding their cardiovascular (CV safety. Furthermore, while the safety of LAMA and LABA monotherapy has been extensively studied, data are lacking for LAMA/LABA combination therapy, and the majority of the studies that have reported on the CV safety of LAMA/LABA combination therapy were not specifically designed to assess this. Evaluation of CV safety for COPD treatments is important because many patients with COPD have underlying CV comorbidities. However, severe CV and other comorbidities are often exclusion criteria for RCTs, contributing to a lack in external validity and generalizability. Real-world observational studies are another important tool to evaluate the effectiveness and safety of COPD therapies in a broader population of patients and can improve upon the external validity limitations of RCTs. We examine what is already known regarding the CV and cerebrovascular safety of LAMA/LABA combination therapy from RCTs and real-world observational studies, and explore the advantages and

Roflumilast, an oral, selective phosphodiesterase-4-inhibitor reduces exacerbations and improves lung function in severe/very severe COPD patients with a history of exacerbations. This study aimed to estimate the lifetime cost and outcomes of roflumilast added-on to commonly used COPD regimens in Switzerland.Methods: A Markov cohort model was developed to simulate COPD progression in patients with disease states of severe, very severe COPD, and death. The exacerbation rate was assumed to be two per year in severe COPD. COPD progression rates were drawn from the published literature. Efficacy was expressed as relative ratios of exacerbation rates associated with roflumilast, derived from a mixed-treatment comparison. A cost-effectiveness analysis was conducted for roflumilast added to long-acting muscarinic antagonists (LAMA, long-acting ß2-agonist/inhaled corticosteroids (LABA/ICS, and LAMA + LABA/ICS. The analysis was conducted from the Swiss payer perspective, with costs and outcomes discounted at 2.5% annually. Parameter uncertainties were explored in one-way and probabilistic sensitivity analyses.Results: In each of the comparator regimens mean life expectancy was 9.28 years and quality-adjusted life years (QALYs gained were 6.19. Mean estimated lifetime costs per patient in the comparator arms were CHF 83,364 (LAMA, CHF 88,161 (LABA/ICS, and CHF 95,564 (LAMA + LABA/ICS respectively. Adding roflumilast resulted in a mean cost per patient per lifetime of CHF 86,754 (LAMA + roflumilast, CHF 91,470 (LABA/ICS + roflumilast, and CHF 99,364 (LAMA + LABA/ICS + roflumilast

    Full Text Available Chronic low back pain (LBP is a prevalent global problem, which is often correlated with degenerative disc disease. The development and use of good, relevant animal models of the spine may improve treatment options for this condition. While no animal model is capable of reproducing the exact biology, anatomy, and biomechanics of the human spine, the quality of a particular animal model increases with the number of shared characteristics that are relevant to the human condition. The purpose of this study was to investigate the camelid (specifically, alpaca and llama cervical spine as a model of the human lumbar spine. Cervical spines were obtained from four alpacas and four llamas and individual segments were used for segmental flexibility/biomechanics and/or morphology/anatomy studies. Qualitative and quantitative data were compared for the alpaca and llama cervical spines, and human lumbar specimens in addition to other published large animal data. Results indicate that a camelid cervical intervertebral disc (IVD closely approximates the human lumbar disc with regard to size, spinal posture, and biomechanical flexibility. Specifically, compared with the human lumbar disc, the alpaca and llama cervical disc size are approximately 62%, 83%, and 75% with regard to area, depth, and width, respectively, and the disc flexibility is approximately 133%, 173%, and 254%, with regard to range of motion (ROM in axial-rotation, flexion-extension, and lateral-bending, respectively. These results, combined with the clinical report of disc degeneration in the llama lower cervical spine, suggest that the camelid cervical spine is potentially well suited for use as an animal model in biomechanical studies of the human lumbar spine.

    Members of the genus Sarcocystis (Apicomplexa: Sarcocystidae) are intracellular protozoan parasites that infect a wide range of domestic and wild animals, resulting in economic losses in production animals worldwide. Sarcocystis spp. have indirect life-cycles where canids and felids serve as main definitive hosts while a range of domestic and wild animals serve as intermediate hosts, including South American camelids (SACs) such as alpacas, llamas and guanacos. These animals primarily occur in South American countries on Andean, elevated plains but in recent years, alpacas and llamas have become emerging animal industries in other parts of the world such as Australia, Europe and the USA due to their high-quality fiber, meat and hides. For instance, alpaca meat is becoming popular in many parts of the world due to its lower cholesterol content than other red meat, thereby it has the potential of a valuable product for both local and international markets. However, SAC meat can be degraded and/or even condemned due to the presence of macroscopic sarcocysts in skeletal muscles, leading to significant economic losses to farmers. The infection is generally asymptomatic, though highly pathogenic or even fatal Sarcocystis infections have also been reported in alpacas and llamas. Despite the economic importance of sarcocystosis in SACs, little is known about the life-cycle of parasites involved, disease transmission, epidemiology, pathogenesis, diagnosis, control and public health significance. This review article provides an in-depth analysis of the existing knowledge on the taxonomy, epidemiology, clinicopathology and diagnosis of Sarcocystis in SACs, highlights knowledge gaps and proposes future areas of research that could contribute to our better understanding of sarcocystosis in these animals.

    2004-04-01

    For determining the adequacy of ventilation, conventional pulse oximetry should be amended by PaCO2 (= arterial carbon dioxide partial pressure). This study investigates the precision of carbon dioxide measurements of the first digital ear-clip sensor providing continuous non-invasive monitoring of PaCO2, SpO2 (= functional arterial oxygen saturation as estimated with a pulse oximeter) and pulse rate and compares it to two conventional analog oximeters. 30 hypoxemia episodes in 6 adult volunteers were investigated in a standardized protocol. Masimo analog finger sensor, Nellcor analog ear sensor, SenTec digital ear sensor. The difference between PCO2 data (= PaCO2 estimated from the measured PcCO2 based on an algorithm by Severinghaus) (PcCO2 = cutaneous carbon dioxide pressure) and the PaCO2 is clinically unimportant. Therefore, we suggest, the two methods of estimating patient's carbon dioxide status can be used interchangeably. Combined digital SpO2/ PcCO2 ear sensors are very promising to allow for a fast and reliable monitoring of patient's oxygenation, hyper-/hypocapnia and ventilation with one single non-invasive probe. Optimal primary signal processing--amplification and digitalisation within the probe--allow for fast and reliable downstream signal processing algorithms. The resulting short SpO2 response times give the medical staff more time to take appropriate actions.

    The authors investigated the accuracy of transcutaneous capnometry (TcPCO(2)) in estimating arterial blood carbon dioxide partial pressure (PaCO(2)) during spontaneous breathing in patients admitted to our surgical intensive care unit (ICU). Serial TcPCO(2) and PaCO(2) measurements were taken in stable patients undergoing postoperative monitoring after major abdominal, vascular, or thoracic surgery. Patients were enrolled 12 hours after extubation. Exclusion criteria were pulmonary dysfunction, hemodynamic instability, or anemia. Linear regression, mixed models, and Bland-Altman analyses were used to compare accuracy and correlation between the two variables. Data are presented as means (95% confidence intervals). PaCO(2) values ranged between 26 mmHg and 52 mmHg. Mean values for TcPCO(2) and PaCO(2) were 35.3 (33.8-36.8) mmHg and 39.2 (37.6-40.7) (Pbreathing, nonintubated patients in the early postoperative period.

  12. Renal acidification responses to respiratory acid-base disorders.

    2010-01-01

    Respiratory acid-base disorders are those abnormalities in acid-base equilibrium that are expressed as primary changes in the arterial carbon dioxide tension (PaCO2). An increase in PaCO2 (hypercapnia) acidifies body fluids and initiates the acid-base disturbance known as respiratory acidosis. By contrast, a decrease in PaCO2 (hypocapnia) alkalinizes body fluids and initiates the acid-base disturbance known as respiratory alkalosis. The impact on systemic acidity of these primary changes in PaCO2 is ameliorated by secondary, directional changes in plasma [HCO3¯] that occur in 2 stages. Acutely, hypercapnia or hypocapnia yields relatively small changes in plasma [HCO3¯] that originate virtually exclusively from titration of the body's nonbicarbonate buffers. During sustained hypercapnia or hypocapnia, much larger changes in plasma [HCO3¯] occur that reflect adjustments in renal acidification mechanisms. Consequently, the deviation of systemic acidity from normal is smaller in the chronic forms of these disorders. Here we provide an overview of the renal acidification responses to respiratory acid-base disorders. We also identify gaps in knowledge that require further research.

    To assess the accuracy of measurements of end tidal carbon dioxide (CO2) during neonatal transport compared with arterial and transcutaneous measurements. Paired end tidal and transcutaneous CO2 recordings were taken frequently during road transport of 21 ventilated neonates. The first paired CO2 values were compared with an arterial blood gas. The differences between arterial CO2 (Paco2), transcutaneous CO2 (TcPco2), and end tidal CO2 (Petco2) were analysed. The Bland-Altman method was used to assess bias and repeatability. Petco2 correlated strongly with Paco2 and TcPco2. However, Petco2 underestimated Paco2 at a clinically unacceptable level (mean (SD) 1.1 (0.70) kPa) and did not trend reliably over time within individual subjects. The Petco2 bias was independent of Paco2 and severity of lung disease. Petco2 had an unacceptable under-recording bias. TcPco2 should currently be considered the preferred method of non-invasive CO2 monitoring for neonatal transport.

    Transcutaneous oxygen (TcPo2) and carbon dioxide (TcPco2) tensions were compared with arterial values in 23 children aged 4 months to 14 years, all requiring some form of respiratory support, but not in shock. Electrodes were placed on the upper chest and were heated to 45 degrees C. For TcPo2 and arterial oxygen (Pao2) a tight linear correlation over the range 6 to 14 kPa was found. Arterial carbon dioxide (Paco2) ranged between 2.63 and 6.8 kPa, and over this range a linear regression adequately described the relation of TcPco2 to Paco2. No effects of age were found for the relation between TcPo2 and Pao2. Over a four hour period, the mean ratio TcPo2/Pao2 rose significantly from 0.96 to 1.04, while the mean ratio of TcPco2/Paco2 fell from 1.65 to 1.62. Five children developed superficial burns which were still present at 48 hours. In children who require respiratory support but are not in shock, TcPo2 and TcPco2 bear a constant and predictable relation to Pao2 and Paco2, and can predict arterial values within clinically acceptable tolerances.

    Partially acetylated chitosan oligosaccharides (paCOS) have various potential applications in agriculture, biomedicine, and pharmaceutics due to their suitable bioactivities. One method to produce paCOS is partial chemical hydrolysis of chitosan polymers, but that leads to poorly defined mixtures of oligosaccharides. However, the effective production of defined paCOS is crucial for fundamental research and for developing applications. A more promising approach is enzymatic depolymerization of chitosan using chitinases or chitosanases, as the substrate specificity of the enzyme determines the composition of the oligomeric products. Protein-engineering of these enzymes to alter their substrate specificity can overcome the limitations associated with naturally occurring enzymes and expand the spectrum of specific paCOS that can be produced. Here, engineering the substrate specificity of Bacillus sp. MN chitosanase is described for the first time. Two muteins with active site substitutions can accept N-acetyl-D-glucosamine units at their subsite (-2), which is impossible for the wildtype enzyme. © 2017 Wiley Periodicals, Inc.

    We tested the claim that inter-individual CBF variability in Alzheimer's disease (AD) is substantially reduced after correction for arterial carbon dioxide tension (PaCO(2)). Specifically, we tested whether the variability of CBF in brain of patients with AD differed significantly from brain of age...

    Direct colloid osmometry provides an objective assessment of the oncotic effects of crystalloid or colloidal fluid therapy, which is especially useful in monitoring fluid therapy of critically ill camelids due to their tendency toward nonspecific hypoproteinemia with increased risk of developing edema and ascites. The aims of this study were to measure colloid osmotic pressure (COP) of alpacas and llamas, determine its correlation with concentrations of total protein (TP) and total solids (TS), as well as both albumin (A) and globulin (G) concentrations in the same model (A+G), and evaluate the effects of sample type and storage conditions on COP. Blood was collected from clinically healthy alpacas (n=23) and llamas (n=22) into heparin tubes. COP of fresh whole blood (COP(FB) ) and plasma (COP(FP) ) was determined using a membrane osmometer. For 20 alpacas, COP of refrigerated whole blood (COP(RB) ) and frozen plasma (COP(FrP) ) was also measured. Correlations between COP(FB) and TS, TP, and A+G concentrations were assessed by simple and multiple regression analysis to model potential predictors. Median COP(FB) from alpacas (24.6 mmHg, range 19.3-28.1) was not significantly different from that of llamas (25.3 mmHg, range 22.5-33.7). Sample type or storage conditions did not affect COP. Measured COP had a strong positive linear correlation with TS, TP, and A+G concentrations in alpacas (r(2) =.7, .74, and .88, respectively). In llamas, COP correlated best with TS concentration (r(2) =.59), whereas correlation with TP and A+G concentrations was poor (r(2) =.19 and .25, respectively). COP can be measured using heparinized whole blood or plasma, either fresh or stored. Direct measurement is recommended whenever quantitative knowledge of COP is required in clinical or research setting. Further studies are needed to verify if the poor association of COP with TP found in this study can be generalized to llamas. ©2011 American Society for Veterinary Clinical Pathology.

    BACKGROUND: Most guidelines recommend either a long-acting beta-agonist (LABA) plus an inhaled glucocorticoid or a long-acting muscarinic antagonist (LAMA) as the first-choice treatment for patients with chronic obstructive pulmonary disease (COPD) who have a high risk of exacerbations. The role ...
