Abstract (sommario):

ABSTRACT 3-Oxoadipate:succinyl-coenzyme A (CoA) transferase and 3-oxoadipyl-CoA thiolase carry out the ultimate steps in the conversion of benzoate and 3-chlorobenzoate to tricarboxylic acid cycle intermediates in bacteria utilizing the 3-oxoadipate pathway. This report describes the characterization of DNA fragments with the overall length of 5.9 kb from Pseudomonas sp. strain B13 that encode these enzymes. DNA sequence analysis revealed five open reading frames (ORFs) plus an incomplete one. ORF1, of unknown function, has a length of 414 bp. ORF2 (catI) encodes a polypeptide of 282 amino acids and starts at nucleotide 813. ORF3 (catJ) encodes a polypeptide of 260 amino acids and begins at nucleotide 1661. CatI and CatJ are the subunits of the 3-oxoadipate:succinyl-CoA transferase, whose activity was demonstrated when both genes were ligated into expression vector pET11a. ORF4, termed catF, codes for a protein of 401 amino acid residues with a predicted mass of 41,678 Da with 3-oxoadipyl-CoA thiolase activity. The last three ORFs seem to form an operon since they are oriented in the same direction and showed an overlapping of 1 bp between catI and catJ and of 4 bp between catJ and catF. Conserved functional groups important for the catalytic activity of CoA transferases and thiolases were identified in CatI, CatJ, and CatF. ORF5 (catD) encodes the 3-oxoadipate enol-lactone hydrolase. An incomplete ORF6 of 1,183 bp downstream of ORF5 and oriented in the opposite direction was found. The protein sequence deduced from ORF6 showed a putative AMP-binding domain signature.

Abstract (sommario):

ABSTRACT In the present study, we sought to elucidate the contribution of the Cryptococcus neoformans catalase gene family to antioxidant defense. We employed bioinformatics techniques to identify four members of the C. neoformans catalase gene family and created mutants lacking single or multiple catalase genes. Based on a phylogenetic analysis, CAT1 and CAT3 encode putative spore-specific catalases, CAT2 encodes a putative peroxisomal catalase, and CAT4 encodes a putative cytosolic catalase. Only Cat1 exhibited detectable biochemical activity in vitro, and Cat1 activity was constitutive in the yeast form of this organism. Although they were predicted to be important in spores, neither CAT1 nor CAT3 was essential for mating or spore viability. Consistent with previous studies of Saccharomyces cerevisiae, the single (cat1, cat2, cat3, and cat4) and quadruple (cat1 cat2 cat3 cat4) catalase mutant strains exhibited no oxidative-stress phenotypes under conditions in which either exogenous or endogenous levels of reactive oxygen species were elevated. In addition, there were no significant differences in the mean times to mortality between groups of mice infected with C. neoformans catalase mutant strains (the cat1 and cat1 cat2 cat3 cat4 mutants) and those infected with wild-type strain H99. We conclude from the results of this study that C. neoformans possesses a robust antioxidant system, composed of functionally overlapping and compensatory components that provide protection against endogenous and exogenous oxidative stresses.

Abstract (sommario):

Abstract Recent research has attempted to examine the proportion of interviewer variance that is due to interviewers systematically varying in their success in obtaining cooperation from respondents with varying characteristics (i.e., nonresponse error variance), rather than variance among interviewers in systematic measurement difficulties (i.e., measurement error variance) - that is, whether correlated responses within interviewers arise due to variance among interviewers in the pools of respondents recruited, or variance in interviewer-specific mean response biases. Unfortunately, work to date has only considered data from a CATI survey, and thus suffers from two limitations: Interviewer effects are commonly much smaller in CATI surveys, and, more importantly, sample units are often contacted by several CATI interviewers before a final outcome (response or final refusal) is achieved. The latter introduces difficulties in assigning nonrespondents to interviewers, and thus interviewer variance components are only estimable under strong assumptions. This study aims to replicate this initial work, analyzing data from a national CAPI survey in Germany where CAPI interviewers were responsible for working a fixed subset of cases.

Abstract (sommario):

Background: Feline demodicosis is considered an uncommon dermatopathy in cats that is mainly caused by the mite Demodex cati, but in few cases D. gatoi may be involved. Although the clinical aspects and pathogeny of feline demodicosis are not completely understood, its clinical expression is believed to be associated with the presence of primary immunosuppressive agents. Thus, the aim of this study is to report the diagnosis and treatment of an infested cat by D. cati, associated with mixed intestinal parasitic infection. Case: An approximately 1-year-old male short hair cat which was grown in a rural area was presented at the Veterinary Hospital of the Federal University of Pampa (Unipampa) in Uruguaiana, Rio Grande do Sul. The cat had alopecia, itching, excoriations on neck and head, and softened feces as clinical signs. Performed skin scrapings revealed eggs, larvae and adult forms of D. cati. In order to fnd possible immunosuppressive agents, exams for detection of feline immunodefciency virus (FIV) and feline leukemia virus (FeLV) were also performed. They revealed, however, negative results for FIV and FeLV infections. Moreover, coproparasitologic analysis revealed the presence of the intestinal parasites Trichuris sp., Ancylostoma sp., and Spirometra mansonoides. Thus, it was decided to proceed the treatment utilizing 0.2 mg/kg of moxidectin subcutaneously every four days and weekly shower with antiseptic shampoo containing 0.15% triclosan. In addition, it was prescribed oral doses of febendazol (50 mg/kg/day) for four days. After 20 days of treatment, the skin lesions had decreased signifcantly and the skin scrapings were negative for D. cati. In this way, the showers with 0.15% triclosan was suspended. Nevertheless, the treatment with moxidectin was maintained for more fours weeks until totalclinical healing was achieved with hair growth and absence of skin lesions. Furthermore, after the treatment with febendazol the animal feces had reached a normal consistency and new coproparasitologic analysis revealed negative results for the presence of intestinal parasites. Discussion: The diagnosis of Demodex cati was based on clinical history, physical examination (alopecia, excoriation in the head and neck) and microscopic visualization of the mite in skin scrapings. The treatment used with moxidectin, acaricidal quite safe and effective, widely used in treatment of canine demodicosis, but no reports about the use in cats. The mite D. cati is considered normal resident of cat’s skin, and the pathogenesis of demodicosis is still unknown. It is known that the playback exacerbated mite can present with skin lesions is commonly associated with immunosuppression states. The presence of three different intestinal parasites (Spirometra mansonoides, Trichuris sp., and Ancylostoma sp.) might have been essential for an immunosuppressive status of the cat and clinical development of demodicosis. Thus, this report supports the hypothesis that a primary immunosuppressive agent is necessary for clinical development of feline demodicosis. Nevertheless, further researches are necessary in order to determine the prevalence of feline demodicosis and correlate the presence of cestodes and development of this disease. In addition, this report highlights the therapeutic success utilizing na association of moxidectin and topic treatment with the treatment of possible immunosuppressive agents.Keywords: dermatopathy, imunossuppression, cat, therapy

Abstract (sommario):

This study was aimed to identify the ultra structural morphology of Toxocara cati First Stage Larvae and Second Stage Larvae using Light Microscope. Toxocara cati larvae were obtained from adult worm eggs then were treated in phospat buffer saline with comparasion 1 : 1 until it reached the stage of larvae 1 and 2. The shell of egg Toxocara cati were thick and usually consist of three layers. The first layer was inner membrane, the second layer was middle layer and the third was outer layer. The results of larvae morphology that were identified using light microscope showed that the anterior part of Toxocara cati first stage larvae has a dorsal lip and esophagus and intestine on the posterior part but it could not be identified perfectly. The anterior part of Toxocara cati second stage larvae that were identified has three lips that leads directly into the oesophagus. Three lips on the anterior part of Toxocara cati larvae 2 consist of a dorsal lip and two subventral lips. Morphological of Toxocara cati larvae similar with the Toxocara cati adult worms because morphology of larvae and adult stage was difficult to differentiated.

Abstract (sommario):

Whether computer assisted data collection methods should be used for survey data collection is no longer an issue. Most professional research organizations, commercial, government and academic, are adopting these new methods with enthusiasm. Computer assisted telephone interviewing (CATI) is most prevalent, and computer assisted personal interviewing (CAPI) is rapidly gaining in popularity. Also, new forms of electronic reporting of data using computers, telephones and voice recognition technology are emerging. This paper begins with a taxonomy of current computer assisted data collection methods. It then reviews conceptual and theoretical arguments and empirical evidence on such topics as: (1) respondents and interviewer acceptance of new techniques, (2) effect of computer assisted interviewing on data quality, (3) consequences for survey costs and (4) centralized vs. decentralized deployment of CATI.

Abstract (sommario):

Abstract Prospect theory states that the influential power of avoiding negative outcomes is stronger than that of achieving positive outcomes. In a survey context, this theory has been tested with respect to not only participation in a CATI survey, but also giving consent to data linkage in CATI surveys. No study, however, has tested the theory with respect to participation in a CAPI or web survey. This study does so in a mixed-mode panel context; it also tests the moderating effects of time-in-panel, response history, and mode protocol. Results show that the framing of the survey participation request influences participation propensity in a way consistent with prospect theory, but only for relatively recent panel entrants. The opposite effect is found for long-term panel participants. No difference is found between mode protocols.

Abstract (sommario):

Il presente contributo fornisce una preliminare analisi urbanistica e architettonica dell'area forense e delle relative strutture portate alla luce durante le campagne di scavo 2013-2017, presso il municipium di Forum Sempronii. Allo stato attuale sono stati identi cati, a livello di fondazione, la piazza del foro e i portici che la delimitavano; sul lato Nord dello spazio forense sono stati identi cati tre templi, dei quali il Tempio A interamente scavato. Al di fuori del limite orientale del forum e in posizione prospiciente alla via Flaminia, è stato rinvenuto, in buono stato di conservazione, una terza struttura con probabile funzione cultuale e amministrativa e identi cata come l'Augusteum di Forum Sempronii. Dai dati nora emersi, sembrerebbe possibile ipotizzare la pertinenza di tutte le strutture a una imponente riforma urbanistica e architettonica del municipium avvenuta in epoca augustea.

The aims of this research were to estimate the prevalence and to determine the risk factors related to Toxocara cati (T. cati) infection in pet cats in Bogor. This study was cross sectional study using two types of data; laboratory examination results of feces samples and interview results of the cat owner using a structured questionnaires including characteristics of pet owner and pet care management. The data obtained from this study was analyzed using chi-square test. The results showed that 85 of 243 cats were positively infected by T. cati with 35% prevalence. The significant risk factor associated with the T. cati infection were: sex, sand provided, deworming and type of feed. Pet care management in Kota Bogor were well managed, however the prevalence of T. cati infection was still high. Therefore it can be a potential public health problem especially on cat owners.

Abstract (sommario):

Improvements in vehicular tracking with Global Positioning Systems (GPSs) have fostered new analysis methods in transportation planning. Emerging geographical information systems have helped in developing new techniques in the collection and analysis of data specifically for travel demand forecasting. In 2002, more than 150 households in Laredo, Texas, participated in a GPS-enhanced household travel survey. Trip diary data were collected by means of a computer-assisted telephone interview (CATI), and GPS trip data were collected from survey participants’ vehicles. For trip purpose, a comparison of the two data sets yielded significant results. It was found that the number of trips in the GPS data was much greater than the number reported in the CATI data. Despite that, almost all home-based work (HBW) trips found in the GPS data were also found in the CATI data. That result differs sharply from the other trip purposes: home-based nonwork (HBNW) and non-home-based (NHB); for these two trip purposes, less than half the trips found in the GPS data were found in the CATI data. That result indicates the potential for serious deficiencies in the CATI process for collecting certain types of trips in the region of study. In additional, household size and household income were found to be significant factors affecting the reporting accuracy in the CATI data. Despite that, the CATI method of household trip data retrieval is still considered to be an effective and valuable tool.

Abstract (sommario):

Toxocara canis and Toxocara cati are known as common roundworm in dogs and cats, respectively. The objective of the current study was to determine the molecular prevalence and risk factors associated with T. canis and T. cati infections in stray dogs and cats, respectively, in Bangkok, Thailand. In total, 1000 fecal samples (from 500 dogs and 500 cats) were collected from stray dogs and cats residing in Bangkok temples. DNA was extracted and screened for T. canis and T. cati using polymerase chain reaction (PCR) with the internal transcribed spacer (ITS) region. The overall prevalence of T. canis in the stray dogs was 5.4% (27/500) and 0.6% (3/500) for T. cati in the stray cats. Toxocara canis infections were detected in stray dogs from 11 out of 48 districts (22.9%), with Bang Khen district having the highest proportion of infected dogs, whereas T. cati infections were only detected in the stray cats in Lat Krabang district. These results indicated that stray animals residing in Bangkok temples pose a considerable public health risk due to zoonotic parasites, especially T. canis.

Abstract To get an overview on the prevalence of intestinal helminths, between 2010 and 2012, fecal samples from 215 stray cats from area of Thessaloniki, Greece, were tested by coprological methods. From the total number of fecal samples examined, 55.8 % were infected with at least one intestinal parasite and 16.3 % had co-infection. Five different parasite species were found. The most prevalent helminth was Dipylidium caninum (39.53 %), followed by Toxocara cati (18.14 %), Ancylostoma spp. (11.63 %), Taenia taeniaeformis (8.37 %) and Toxascaris leonina (0.93 %). The results showed that A. tubaeforme and T. taeniaeformis were more prevalent in males, while D. caninum, T. cati and T. leonina in female cats, without statistical significance. The prevalence of Ancylostoma spp. and T. cati were significantly higher in young cats (< 1 year old) than in adults (> 1 year old). The most common association was between D. caninum and T. cati.

Abstract (sommario):

Macfadyena unguis-cati (L.) Gentry (Bignoniaceae) is a major environmental weed in coastal Queensland, Australia. There is a lack of quantitative data on its leaf chemistry and its impact on soil properties. Soils from infested vs uninfested areas, and leaves of M. unguis-cati and three co-occurring vine species (one exotic, two native) were collected at six sites (riparian and non-riparian) in south-eastern Queensland. Effects of invasion status, species, site and habitat type were examined using univariate and multivariate analyses. Habitat type had a greater effect on soil nutrients than on leaf chemistry. Invasion effect of M. unguis-cati on soil chemistry was more pronounced in non-riparian than in riparian habitat. Significantly higher values were obtained in M. unguis-cati infested (vs. uninfested) soils for ~50% of traits. Leaf ion concentrations differed significantly between exotic and native vines. Observed higher leaf-nutrient load (especially nitrogen, phosphorus and potassium) in exotic plants aligns with the preference of invasive plant species for disturbed habitats with higher nutrient input. Higher load of trace elements (aluminium, boron, cadmium and iron) in its leaves suggests that cycling of heavy-metal ions, many of which are potentially toxic at excess level, could be accelerated in soils of M. unguis-cati-invaded landscape. Although inferences from the present study are based on correlative data, the consistency of the patterns across many sites suggests that M. unguis-cati may improve soil fertility and influence nutrient cycling, perhaps through legacy effects of its own litter input.

Abstract (sommario):

The ascaridoid nematode of cats from Kuala Lumpur, Malaysia, previously identified morphologically as Toxocara canis, was characterized using a molecular approach. The nuclear ribosomal DNA (rDNA) region spanning the first internal transcribed spacer (ITS-1), the 5·8S gene and the second internal transcribed spacer (ITS-2) was amplified and sequenced. The sequences for the parasite from Malaysian cats were compared with those for T. canis and T. cati. The sequence data showed that this taxon was genetically more similar to T. cati than to T. canis in the ITS-1, 5·8S and ITS-2. Differences in the ITS-1 and ITS-2 sequences between the taxa (9·4–26·1%) were markedly higher than variation between samples within T. canis and T. cati (0–2·9%). The sequence data demonstrate that the parasite from Malaysian cats is neither T. canis nor T. cati and indicate that it is a distinct species. Based on these data, PCR-linked restriction fragment length polymorphism (RFLP) and single-strand conformation polymorphism (SSCP) methods were employed for the unequivocal differentiation of the Toxocara variant from T. canis and T. cati. These methods should provide valuable tools for studying the life-cycle, transmission pattern(s) and zoonotic potential of this parasite.

Abstract (sommario):

Background Targeting interventions to areas that have recently experienced cases of disease is one strategy to contain outbreaks of infectious disease. Such case-area targeted interventions (CATI) have become an increasingly popular approach for dengue control but there is little evidence to suggest how precisely targeted or how recent cases need to be, to mount an effective response. The growing interest in the development of prophylactic and therapeutic drugs for dengue has also given new relevance for CATI strategies to interrupt transmission or deliver early treatment. Methods/Principal findings Here we develop a patch-based mathematical model of spatial dengue spread and fit it to spatiotemporal datasets from Singapore. Simulations from this model suggest CATI strategies could be effective, particularly if used in lower density areas. To maximise effectiveness, increasing the size of the radius around an index case should be prioritised even if it results in delays in the intervention being applied. This is partially because large intervention radii ensure individuals receive multiple and regular rounds of drug dosing or vector control, and thus boost overall coverage. Given equivalent efficacy, CATIs using prophylactic drugs are predicted to be more effective than adult mosquito-killing vector control methods and may even offer the possibility of interrupting individual chains of transmission if rapidly deployed. CATI strategies quickly lose their effectiveness if baseline transmission increases or case detection rates fall. Conclusions/Significance These results suggest CATI strategies can play an important role in dengue control but are likely to be most relevant for low transmission areas where high coverage of other non-reactive interventions already exists. Controlled field trials are needed to assess the field efficacy and practical constraints of large operational CATI strategies.

Abstract (sommario):

Toxocara cati is a common parasite of wild and domestic felines, and presents a cosmopolitan distribution. Adult parasites localize in the gut of the definitive host giving rise to the infection, which usually runs asymptomatic. These worms produce eggs that are excreted with feces into the environment, where they become a source of infection for paratenic hosts, such as mammals, birds, and invertebrates. In this brief communication, we report the detection of T. cati larvae in a common buzzard (Buteo buteo) and a red kite (Milvus milvus), in the Basilicata Region of Italy. This result may be important to define new pathways of spread and survival of T. cati in the wild.

Abstract (sommario):

The aniline-assimilating bacterium Rhodococcus sp. AN-22 was found to constitutively synthesize CatB (cis,cis-muconate cycloisomerase) and CatC (muconolactone isomerase) in its cells growing on non-aromatic substrates, in addition to the previously reported CatA (catechol 1,2-dioxygenase). The bacterium maintained the specific activity of the three enzymes at an almost equal level during cultivation on succinate. CatB and CatC were purified to homogeneity and characterized. CatB was a monomer with a molecular mass of 44 kDa. The enzyme was activated by Mn2+, Co2+ and Mg2+. Native CatC was a homo-octamer with a molecular mass of 100 kDa. The enzyme was stable between pH 7.0 and 10.5 and was resistant to heating up to 90 °C. Genes coding for CatA, CatB and CatC were cloned and named catA, catB and catC respectively. The catABC genes were transcribed as one operon. The deduced amino acid sequences of CatA, CatB and CatC showed high identities with those from other Gram-positive micro-organisms. A regulator gene such as catR encoding a regulatory protein was not observed around the cat gene cluster of Rhodococcus sp. AN-22, but a possible relic of catR was found in the upstream region of catA. Reverse transcriptase-PCR and primer extension analyses showed that the transcriptional start site of the cat gene cluster was located 891 bp upstream of the catA initiation codon in the AN-22 strain growing on both aniline and succinate. Based on these data, we concluded that the bacterium constitutively transcribed the catABC genes and translated its mRNA into CatA, CatB and CatC.

Abstract (sommario):

AbstractToxocariasis is the clinical syndrome caused by infection of zoonotic roundworms of dogs (Toxocara canis) or cats (Toxocara cati). Current research on the immunology and pathology aspects of toxocariasis requires Toxocara second stage larvae and a ready source of excretory-secretory (ES) antigens. We cultured eleven pairs of both sexes of Toxocara cati adult worms maintained in RPMI 1640 medium in order to evaluate the amounts and duration of egg laying. At the first day and last day (day 19), the mean egg counts were 9300 and 250 eggs/ml, respectively. These results showed that this culture method is very appropriate for collection of pure oviposited eggs and/or production of adult ES antigens of Toxocara cati that could be used for immunological diagnosis of toxocariasis.

Abstract (sommario):

To assess the validity of survey data collected from computer assisted telephone interviews (CATI) for the prediction of retention behavior, data from 754 AF pilots were collected at two points in time. In January 1988 these pilots took part in a CATI study that revealed their intentions to sign contracts for additional years of military service in return for bonus payments of up to $12,000 per year. Beginning in January 1989, these pilots were offered aviation bonus contracts, similar to those studied with the CATI, under the Aviator Continuation Pay (ACP) program enacted by Congress. Two key variables from the survey—career intent and bonus intent—were very accurate in predicting ACP behavior at both the aggregate and the entity levels.

Abstract (sommario):

This study explores the effects of call attempts and time periods on call outcomes and sample composition. A mobile computer-assisted telephone interview survey was conducted to collect data from adult mobile phone users about use and attitudes towards mobile phones; paradata regarding call dispositions, time and day of the week of calls and number of call attempts was also available. The first call contact rate was approximately 27% and varied significantly across time periods; the rate fell to below 20% for the second call. Weekend time periods yielded higher contact rates than weekday time periods. The interview rate on the first call was 12% and decreased steadily in subsequent calls. Mobile phone numbers that yielded call rejection, voicemail or were busy on the first call were very difficult to convert into interview on the second call. The number of call attempts and time period of the calls affect sample composition, namely in relation to respondents' age, educational level and area of residence. Future research and practical implications of the findings for mobile CATI surveys are discussed.

Abstract (sommario):

Toxocariasis is a zoonotic infection transmitted from animals to humans caused by parasitic round worms found in dogs and cats. Ocular toxocariasis is a rare condition caused by toxocara cati that can result in monocular loss of vision. We report an accidental finding of loss of vision in the right eye of a 39-year-old who decided to get an ocular examination following a routine prep talk in an outpatient clinic. Patient was asymptomatic and presenting best corrected visual acuity in the right eye was 6/60. Fundus examination revealed multiple discrete granulomas and a fatty liver revealed on abdominal scan. There is a positive history of living with cats while growing up. We presume this to be a case of toxocara cati. Regular ocular examinations in addition to general medical check-up should be encouraged in pet owners and those handling animals, as well as a high index of suspicion amongst ophthalmologists.

Abstract (sommario):

Intestinal parasites are involved in the health and wellbeing of cats and some of them, due to their zoonotic potential, represent a problem for public health. This study aimed to assess the prevalence of parasitic infections in cats with gastrointestinal signs. Fecal samples collected from 137 cats were analyzed by the flotation method using a sodium chloride saturated solution. The overall prevalence of intestinal parasites was 50.4%. Intestinal parasites were significantly (p < 0.0001) more common in cats with digestive clinical signs (66.7%) than in clinically healthy ones (19.2%). Toxocara cati (40.2%) was the most frequently identified intestinal parasite, followed by Cystoisospora spp. (10.2%), hookworms (3.7%), Taeniidae (2.2%), Giardia duodenalis (2.2%), and Toxoplasma gondii (0.7%). Toxocara cati (53.3%, p < 0.0001) and Cystoisospora spp. (15.6%, p < 0.001) were significantly more frequently diagnosed in cats with clinical signs. A lack of deworming in the last three months (OR: 15.9), outdoor access (OR: 13.8), the presence of digestive symptoms (OR: 5.4), and young age (OR: 4.2) were identified as risk factors for T. cati infection by logistic regression analysis. Regardless of age, gastrointestinal signs like vomiting, diarrhea, and inappetence were positively associated with T. cati.

Abstract (sommario):

ABSTRACT Detoxification of hydrogen peroxide is a fundamental aspect of the cellular antioxidant responses in which catalases play a major role. Two differentially regulated catalase genes, catA andcatB, have been studied in Aspergillus nidulans. Here we have characterized a third catalase gene, designated catC, which predicts a 475-amino-acid polypeptide containing a peroxisome-targeting signal. With a molecular mass of 54 kDa, CatC shows high similarity to other small-subunit monofunctional catalases and is most closely related to catalases from other fungi, Archaea, and animals. In contrast, the CatA (∼84 kDa) and CatB (∼79 kDa) enzymes belong to a family of large-subunit catalases, constituting a unique fungal and bacterial group. The catC gene displayed a relatively constant pattern of expression, not being induced by oxidative or other types of stress. Targeted disruption of catC eliminated a constitutive catalase activity not detected previously in zymogram gels. However, a catalase activity detected in catA catBmutant strains during late stationary phase was still present incatC and catABC null mutants, thus demonstrating the presence of a fourth catalase, here named catalase D (CatD). Neither catC nor catABC triple mutants showed any developmental defect, and both mutants grew as well as wild-type strains in H2O2-generating substrates, such as fatty acids, and/or purines as the sole carbon and nitrogen sources, respectively. CatD activity was induced during late stationary phase by glucose starvation, high temperature, and, to a lesser extent, H2O2 treatment. The existence of at least four differentially regulated catalases indicates a large and regulated capability for H2O2detoxification in filamentous fungi.

Abstract (sommario):

Smartphones have become very popular globally, and smartphone ownership has overtaken conventional cell phone ownership in many countries in recent years. With this rapid rise in smartphone penetration, researchers are looking at ways to conduct web surveys using smartphones. This is particularly true of student populations where smartphone penetration is very high and web surveys are already the norm. However, researchers are raising concerns about selection biases and measurement differences between PC and smartphone respondents. Questions also remain about comparisons to traditional interviewer-administered approaches. We designed an experimental comparison between a PC web survey, a smartphone web survey and a computer-assisted telephone interviewing (CATI) survey. This study was conducted using an annual survey of students at a large university in South Korea. The CATI (interviewer-administered) survey had a higher response rate, lower margins of error, and better representation of the student population than the two web (self-administered) modes, but at a higher cost. The CATI survey also had lower rates of item nonresponse. More significant differences were found between the modes for sensitive questions than for nonsensitive ones. This suggests that CATI surveys may still have a role to play in surveys of college students, even in a country with high rates of mobile technology adoption.

AbstractThe study was conducted to determine the sequence variation in two mitochondrial genes, namely cytochrome c oxidase 1 (pcox1) and NADH dehydrogenase 1 (pnad1) within and among isolates of Toxocara cati, Toxocara canis and Toxascaris leonina. Genomic DNA was extracted from 32 isolates of T. cati, 9 isolates of T. canis and 19 isolates of T. leonina collected from cats and dogs in different geographical areas of Iran. Mitochondrial genes were amplified by polymerase chain reaction (PCR) and sequenced. Sequence data were aligned using the BioEdit software and compared with published sequences in GenBank. Phylogenetic analysis was performed using Bayesian inference and maximum likelihood methods. Based on pairwise comparison, intra-species genetic diversity within Iranian isolates of T. cati, T. canis and T. leonina amounted to 0–2.3%, 0–1.3% and 0–1.0% for pcox1 and 0–2.0%, 0–1.7% and 0–2.6% for pnad1, respectively. Inter-species sequence variation among the three ascaridoid nematodes was significantly higher, being 9.5–16.6% for pcox1 and 11.9–26.7% for pnad1. Sequence and phylogenetic analysis of the pcox1 and pnad1 genes indicated that there is significant genetic diversity within and among isolates of T. cati, T. canis and T. leonina from different areas of Iran, and these genes can be used for studying genetic variation of ascaridoid nematodes.

Abstract (sommario):

Cat’s claw creeper, Macfadyena unguis-cati (L.) Gentry (Bignoniaceae) is a major environmental weed of riparian areas, rainforest communities and remnant natural vegetation in coastal Queensland and New South Wales, Australia. In densely infested areas, it smothers standing vegetation, including large trees, and causes canopy collapse. Quantitative data on the ecology of this invasive vine are generally lacking. The present study examines the underground tuber traits of M. unguis-cati and explores their links with aboveground parameters at five infested sites spanning both riparian and inland vegetation. Tubers were abundant in terms of density (~1000 per m2), although small in size and low in level of interconnectivity. M. unguis-cati also exhibits multiple stems per plant. Of all traits screened, the link between stand (stem density) and tuber density was the most significant and yielded a promising bivariate relationship for the purposes of estimation, prediction and management of what lies beneath the soil surface of a given M. unguis-cati infestation site. The study also suggests that new recruitment is primarily from seeds, not from vegetative propagation as previously thought. The results highlight the need for future biological-control efforts to focus on introducing specialist seed- and pod-feeding insects to reduce seed-output.

Abstract (sommario):

Background Web-based self-report surveying has increased in popularity, as it can rapidly yield large samples at a low cost. Despite this increase in popularity, in the area of youth mental health, there is a distinct lack of research comparing the results of Web-based self-report surveys with the more traditional and widely accepted computer-assisted telephone interviewing (CATI). Objective The Second Australian Young and Well National Survey 2014 sought to compare differences in respondent response patterns using matched items on CATI versus a Web-based self-report survey. The aim of this study was to examine whether responses varied as a result of item sensitivity, that is, the item’s susceptibility to exaggeration on underreporting and to assess whether certain subgroups demonstrated this effect to a greater extent. Methods A subsample of young people aged 16 to 25 years (N=101), recruited through the Second Australian Young and Well National Survey 2014, completed the identical items on two occasions: via CATI and via Web-based self-report survey. Respondents also rated perceived item sensitivity. Results When comparing CATI with the Web-based self-report survey, a Wilcoxon signed-rank analysis showed that respondents answered 14 of the 42 matched items in a significantly different way. Significant variation in responses (CATI vs Web-based) was more frequent if the item was also rated by the respondents as highly sensitive in nature. Specifically, 63% (5/8) of the high sensitivity items, 43% (3/7) of the neutral sensitivity items, and 0% (0/4) of the low sensitivity items were answered in a significantly different manner by respondents when comparing their matched CATI and Web-based question responses. The items that were perceived as highly sensitive by respondents and demonstrated response variability included the following: sexting activities, body image concerns, experience of diagnosis, and suicidal ideation. For high sensitivity items, a regression analysis showed respondents who were male (beta=−.19, P=.048) or who were not in employment, education, or training (NEET; beta=−.32, P=.001) were significantly more likely to provide different responses on matched items when responding in the CATI as compared with the Web-based self-report survey. The Web-based self-report survey, however, demonstrated some evidence of avidity and attrition bias. Conclusions Compared with CATI, Web-based self-report surveys are highly cost-effective and had higher rates of self-disclosure on sensitive items, particularly for respondents who identify as male and NEET. A drawback to Web-based surveying methodologies, however, includes the limited control over avidity bias and the greater incidence of attrition bias. These findings have important implications for further development of survey methods in the area of health and well-being, especially when considering research topics (in this case diagnosis, suicidal ideation, sexting, and body image) and groups that are being recruited (young people, males, and NEET).
