Abstract

The dispersal process is crucial in determining the fate of populations over time, but habitat fragmentation limits or prevents it. Landscape genetic is an effective tool to assess the degree to which dispersal still occurs in fragmented landscapes. The purpose of this study was to investigate the landscape determinants of genetic differentiation in the hazel dormouse (Muscardinus avellanarius), a forest-dependent species of conservation concern. By comparing subpopulations in a continuous (SLR) and a fragmented (VTH) population, we (i) searched for the presence of Isolation-by-Resistance (IBR); (ii) estimated migration rates; (iii) evaluated the degree of inbreeding and genetic drift, and searched for their landscape determinants. We found an IBR effect in VTH, which heavily hindered the dispersal process. The overall number of migrants among VTH subpopulations was very low (1 per generation, compared to 15 in SLR), although a between-patch displacement of about 4 km along a well-structured hedgerow probably occurred. The inbreeding (F > 0.2 in most subpopulations) and the genetic drift (four out five subpopulations showed private alleles on several loci, with relatively high frequencies) are of particular concern in VTH. However, they were found to be limited in large patches or in patches connected by hedgerows with a high number of neighbouring patches. As a conservation strategy in the VTH landscape, characterized by small patches, we suggest that the dispersal process among subpopulations is enhanced to sustain a functional metapopulation. For this purpose, an effective ecological network should be created by enhancing the continuity and the internal features of hedgerows

Abstract

Habitat fragmentation hinders the dispersal process, which, in turn, causes changes to the genetic variability of populations. The aim of this study was to evaluate the effects of fragmentation on the genetic population features of the hazel dormouse (Muscardinus avellanarius), a small rodent living in forest habitats, using seven microsatellite loci. We compared (i) the genetic variability and population structure, (ii) the scale of the spatial structuring, and (iii) the possible presence and effect of a sex-biased dispersal in two populations living, respectively, in a continuous and in a fragmented landscape in central Italy. Although all microsatellite loci were always polymorphic, in the fragmented population the observed heterozygosity was usually lower than expected, and 5 out of 7 loci were not at Hardy–Weinberg Equilibrium. The fragmented population was found to be strongly structured. These results showed that there was a hindrance of the gene flow between subpopulations, and in some cases even a virtual ecological isolation, as confirmed by the absence of covariation between the pairwise genetic and Euclidean distances. Some clues of female-biased dispersal were found, but even the dispersing sex showed dispersal problems in several cases. The strong differences in the genetic features between the continuous and fragmented population, indicate that the hazel dormouse strongly suffers from habitat fragmentation. This happens even when several neighbouring habitats remnants persist and remain partially connected by verges along crop fields. Thus, the fragmented landscape needs urgent measures to restore ecological connectivity through a more effective management plan of the hedgerows network.

Abstract

Thirty-seven diabetic men selected to exclude the confounding effects of other medical illnesses and nondiabetic medications and 53 healthy controls underwent extensive psychosexual and medical evaluations and penile blood pressure assessments by ultrasonic Doppler measurement and mercury strain-gauge plethysmography. There was a significant negative correlation between age and the penile-brachial index (PBI) in the diabetic but not in the control group. The impotent diabetic group had significantly lower PBI than nondysfunctional diabetic and healthy control subjects. Diabetic type, complications, and adequacy of metabolic control were not statistically related to PBI. Although the PBI may not have diagnostic utility for individual patients, it may provide a valuable noninvasive physiologic measure of penile vascular changes in studies on the aged and the medically ill. The processes that mediate the interaction of diabetes and aging on penile blood pressure and erectile capacity deserve further investigation.

Abstract

To create tomato mutant collections for reverse genetic studies (TILLING), we treated Red Setter tomato seeds with two different Ethylmethanesulfonate (EMS) concentration (0.7% and 1%). A total of 13000 M2 plants, grown in open field, were phenotypically scored for their mutant traits. Two tomato M2 families showed altered colour fruits. Precisely the mutant lines produced fruits that were orange, externally, while their flesh was yellow instead than red.In order to characterize the colour mutant lines, molecular and biochemical studies were undertaken to check the pigment biosynthesis pathways. Total RNA was extracted from mutant and control tomato fruits, reverse transcribed and analyzed by RT-PCR with primers complementary to regions of some genes of the carotenoid (Psy-1, ZDS, PDS, Lyc) and flavonoid (PAL, CHS, CHI) pathways. The qualitative molecular analysis showed differences in gene expression levels not only between colour mutant and control lines (Red Setter) but also between the two EMS mutant tomato genotypes. Interestingly, the molecular results were confirmed and supported by the biochemical ones that showed quantitative differences in secondary metabolites, such as lycopene, beta-carotene (carotenoid pathway), rutin, naringenin and kaemferol (flavonoid pathway), between mutant and control fruits. Our preliminary molecular and biochemical results demonstrated that the two M2 tomato lines, even if phenotypically identical, differed in their carotenoid and flavonoid contents. Further investigations will be undertaken to better characterize the mutant lines not only molecularly (quantitative RT-PCR) and biochemically but also for their protein contents by means of proteomic studies.

Abstract

Patch size, isolation and quality are key factors influencing species persistence in fragmented landscapes. However, we still lack a detailed understanding of how these variables exert their effects on populations inhabiting fragmented landscapes. At which ecological scale do they have an effect (e.g., individuals versus populations) and, on which demographic parameters? Answering these questions will identify the mechanisms that underlie population turnover rather than solely predicting it based on proxies (e.g., presence/absence data). We report the results of a large-scale, three-year study focused on the relative effects of patch size, isolation and quality on individuals and populations of an arboreal rodent, the hazel dormouse (Muscardinus avellanarius). We examined 30 sites nested within three landscapes characterized by contrasting levels of habitat amount and habitat quality (food resources). We quantified the effects of patch size and quality on the response of individuals (survival and litter size) and populations (density and colonization/extinction dynamics). We identified demographic mechanisms which led to population turnover. Habitat quality positively affected survival (not litter size) and population density (measured through an index). We infer that the decline in survival due to patch quality reduced patch recolonization rather than increasing extinction, while extinction was mainly affected by patch size. Our findings suggest that the effect of patch quality on individual and population parameters was constrained by the physical structure of the surrounding landscapes. At the same time, our results highlight the importance of preserving habitat quality to help the persistence of entire systems of patches

Abstract

The negative impact of habitat fragmentation due to human activities may be different in different species that co-exist in the same area, with consequences on the development of environmental protection plans. Here we aim at understanding the effects produced by different natural and anthropic landscape features on gene flow patterns in two sympatric species with different specializations, one generalist and one specialist, sampled in the same locations. We collected and genotyped 194 wood mice (generalist species) and 199 bank voles (specialist species) from 15 woodlands in a fragmented landscape characterized by different potential barriers to dispersal. Genetic variation and structure were analyzed in the two species, respectively. Effective migration surfaces, isolation-by-resistance (IBR) analysis, and regression with randomization were used to investigate isolation-by-distance (IBD) and the relative importance of land cover elements on gene flow. We observed similar patterns of heterozygosity and IBD for both species, but the bank vole showed higher genetic differences among geographic areas. The IBR analysis suggests that (i) connectivity is reduced in both species by urban areas but more strongly in the specialist bank vole; (ii) cultivated areas act as dispersal corridors in both species; (iii) woodlands appear to be an important factor in increasing connectivity in the bank vole, and less so in the wood mouse. The difference in dispersal abilities between a generalist and specialist species was reflected in the difference in genetic structure, despite extensive habitat changes due to human activities. The negative effects of fragmentation due to the process of urbanization were, at least partially, mitigated by another human product, i.e., cultivated terrains subdivided by hedgerows, and this was true for both species.

Abstract

Objectives To describe: (i) factors associated with rapid and delayed ART initiation; (ii) rates of 12 week virological response; and (iii) virologically controlled retention in care by 1 year from ART initiation according to timing of start in a real-life setting. Methods All individuals in the Icona cohort diagnosed with HIV in 2016–17 who initiated ART were grouped according to the time between HIV diagnosis and ART initiation: Group 1, ≤7 days; Group 2, 8–14 days; Group 3, 15–30 days; Group 4, 31–120 days; and Group 5, >120 days. Multivariable logistic regression models were used to identify factors associated with: (i) the probability of rapid (Group 1) and very delayed (Group 5) ART initiation; (ii) the 12 week virological response (by a modified snapshot algorithm); and (iii) the probability of retention in care at 1 year (on ART with HIV-RNA Results A total of 1247 individuals were included [82 (6.6%) in Group 1, 115 (9.2%) in Group 2, 267 (21.4%) in Group 3, 641 (51.4%) in Group 4 and 142 (11.4%) in Group 5]. Main predictors of rapid ART start (Group 1) were low CD4 cell count and high HIV-RNA at first contact with the infectious diseases centre. There was no association between probability of virological response and timing of ART initiation. Overall, 90% of individuals remained on ART after 1 year, 91% with undetectable HIV-RNA. Participants of Italian nationality, those with higher CD4 cell count and lower HIV-RNA at ART initiation were more likely to be retained in care after 1 year. Conclusions In our high-income observational setting, we did not observe differences in the 1 year rate of virological response and retention in care according to timing of ART initiation.

Abstract

ObjectivesTo evaluate the incidence and risk factors for liver enzyme elevations (LEE) in patients initiating first-line ART in the ICONA prospective observational cohort, between June 2009 and December 2017.Patients and methodsIn total, 6575 ART-naive patients were selected, initiating two NRTIs with the third drug being a boosted PI (n=2436; 37.0%), an NNRTI (n=2384; 36.3%) or an integrase strand transfer inhibitor (INSTI) (n=1755; 26.7%). HBV surface antigen and HCV RNA were detected in 3.9% and 5.8% of the study population. Inverse probability weighted Cox regression analysis was used to calculate the HRs, according to first-line regimen, for LEE, defined as ALT or AST increases of ≥2.5× upper limit of normal (ULN) for patients with normal baseline values or ≥2.5× baseline for patients with higher baseline values.ResultsOne hundred and eighty-three LEE occurred over 20722 patient-years of follow-up. After adjusting for the main confounders, the risk of LEE halved with INSTIs compared with NNRTIs (HR 0.46, 95% CI 0.25–0.86), with a significant reduction in the raltegravir group (HR 0.11, 95% CI 0.02–0.84 using the NNRTI class as reference). HRs for LEE were significantly higher in subjects with HBV or HCV coinfection, in patients with poorly controlled HIV infection and in those who acquired HIV through homosexual transmission.ConclusionsIn our study, INSTI use almost halved the risk of LEE compared with other regimens. This finding could be particularly important for choosing ART in patients with risk factors for liver toxicity such as HCV and HBV coinfections.

Abstract

Patch size, isolation and quality are key factors influencing species persistence in fragmented landscapes. However, we still lack a detailed understanding of how these variables exert their effects on populations inhabiting fragmented landscapes. At which ecological scale do they have an effect (e.g., individuals versus populations) and, on which demographic parameters? Answering these questions will identify the mechanisms that underlie population turnover rather than solely predicting it based on proxies (e.g., presence/absence data). We report the results of a large-scale, three-year study focused on the relative effects of patch size, isolation and quality on individuals and populations of an arboreal rodent, the hazel dormouse (Muscardinus avellanarius). We examined 30 sites nested within three landscapes characterized by contrasting levels of habitat amount and habitat quality (food resources). We quantified the effects of patch size and quality on the response of individuals (survival and litter size) and populations (density and colonization/extinction dynamics). We identified demographic mechanisms which led to population turnover. Habitat quality positively affected survival (not litter size) and population density (measured through an index). We infer that the decline in survival due to patch quality reduced patch recolonization rather than increasing extinction, while extinction was mainly affected by patch size. Our findings suggest that the effect of patch quality on individual and population parameters was constrained by the physical structure of the surrounding landscapes. At the same time, our results highlight the importance of preserving habitat quality to help the persistence of entire systems of patches

Abstract

Natural convection heat transfer occurs when the fluid buoyancy motion is induced by density differences themselves caused by the heating. A temperature gradient causes a density variation in a cooling fluid with a related local change in the refractive index. The gradient of refractive index has the effect of bending the light. The thermal load of the device causes an optical deflection in the cooling fluid that an opportune light probe can reveal. Analyzing the deflection of the light probe it is possible to go back to the related temperature gradient. The experimental work in this paper represents a very simple method for the visualization of refractive index non homogeneities in a phase object: the temperature gradients in a cooling fluid for buoyancy-induced convective flow can be visualized in an electronic system during its operation. The developed experimental set-up allows to reveal local refractive index changes in a phase objects. A fringe pattern is acquired, through the cooling fluid under analysis, with a digital camera two times: the first one with the fluid at rest, the second one with the thermal load due to the electronic device normal operation. By the means of the MATLAB processing of the acquired images it's possible to reveal the shape and the directions of the thermal flow lines for the cooling fluid. In this way we can obtain a deeper understanding of the optimal convection working volume or information for the optimization of the relative spatial positioning of the several electronic components in a complex electronic system, like a printed circuit board (PCB). The experimental set-up was optically implemented: the analysis is absolutely no-contact and carried out without distortion for the thermal flow and without alteration for the temperature gradients in the fluid under test. The proposed technique has been applied on two typical heat extraction situations recurrent in the electronic devices: are presented the experimental results of the visualization of the natural convection buoyancy driven air flow for an heat sink and a power resistor. In both the cases it was possible to visualize the bouyancy induced flow generated, in air, by the heated sample and understand the shape of the isogradients lines in the test field and the involved working volume in the cooling fluid. The results presented show that is possible to monitore the onset and the development of the natural convection thermal flow and the perturbation in the thermal gradient map caused by externally added air flow with a simple and cheap noninvasive optical setup.

Abstract

Background: Rat eradication from islands is a very effective tool that can free entire ecosystems from the pressure of alien predators. In this study we present the case study of Ventotene (Ponziane Archipelago, central Italy), which to date is the island with by far the greatest number of human inhabitants ever freed from the negative implications of rats. Rat eradication was carried out in the framework of the Life PonDerat project, co-financed by the European Union. Besides considering the conservation benefits due to the removal of rats, we also considered the socio-economic and pathogenic impacts from introduced rats., Results: The overall economic cost of the rats was quantified to be at least €18 500 per year to the residents of the island. Several zoonotic pathogens were detected in the rat population prior to eradication. A reduction in the rodenticide distributed over time on the island was also estimated. Identifying the origin of the rat population allowed for the development of more targeted and effective biosecurity measures. The eradication effort was challenged by the presence of domestic animals and variability in support for baiting in urbanised areas., Conclusions: The results of this study open up new perspectives on island restoration projects. We demonstrated the cost-effectiveness of the action, including ecosystem restoration, reduction of rat impacts in agricultural systems, and improving overall health and food safety. Our findings will have implications for similar interventions on other islands, potentially bringing significant benefits. © 2023 Society of Chemical Industry., (© 2023 Society of Chemical Industry.)

Abstract

Currently, groin hernia repair is mostly performed with application of mesh prostheses fixed with or without suture. However, views on safety and efficacy of different surgical approaches are still partly discordant. In this multicentre retrospective study, three sutureless procedures, i.e., mesh fixation with glue, application of self-gripping mesh, and Trabucco's technique, were compared in 1034 patients with primary unilateral non-complicated inguinal hernia subjected to open anterior surgery. Patient-related features, comorbidities, and drugs potentially affecting the intervention outcomes were also examined. The incidence of postoperative complications, acute and chronic pain, and time until discharge were assessed. A multivariate logistic regression was used to compare the odds ratio of the surgical techniques adjusting for other risk factors. The application of standard/heavy mesh, performed in the Trabucco's technique, was found to significantly increase the odds ratio of hematomas ( p = 0.014) and, most notably, of acute postoperative pain ( p < 0.001). Among the clinical parameters, antithrombotic therapy and large hernia size were independent risk factors for hematomas and longer hospital stay, whilst small hernias were an independent predictor of pain. Overall, our findings suggest that the Trabucco's technique should not be preferred in patients with a large hernia and on antithrombotic therapy., Competing Interests: The authors declare no conflicts of interest.

Abstract

The spread of the COVID-19 disease substantially influenced the International Healthcare system, and the national governments worldwide had before long to decide how to manage the available resources, giving priority to the treatment of the COVID-infected patients. Then, in many countries, it was decided to limit the elective procedures to surgical oncology and emergency procedures. In fact, most of the routine, middle-low complexity surgical interventions were reduced, and the day surgery (DS) activities were almost totally interrupted. As a result of this approach, the waiting list of these patients has significantly increased. In the current phase, with a significant decrease in the incidence of COVID-19 cases, the surgical daily activity can be safely and effectively restarted. Adjustments are mandatory to resume the DS activity. The whole separation of pathways with respect to the long-stay and emergency surgery, an accurate preoperative protocol of patient management, with a proper selection and screening of all-day cases, careful scheduling of surgical organization in the operating room, and planning of the postoperative pathway are the goals for a feasible, safe, and effective resumption of DS activity., Competing Interests: Conflict of interest: All authors state no conflict of interest., (© 2021 Piergaspare Palumbo et al., published by De Gruyter.)

37. A new fast real-time PCR method for the identification of three sibling Apodemus species ( A. sylvaticus , A. flavicollis , and A. alpicola ) in Italy.

Abstract

The identification of field mice Apodemus flavicollis , Apodemus sylvaticus, and Apodemus alpicola represents a challenge for field scientists due to their highly overlapping morphological traits and habitats. Here, we propose a new fast real-time PCR method to discriminate the three species by species-specific TaqMan assays. Primers and probes were designed based on the alignment of 54 cyt-b partial sequences from 25 different European countries retrieved from GenBank. TaqMan assays were then tested on 133 samples from three different areas of Italy. Real-time PCR analysis showed 92 samples classified as A. flavicollis , 13 as A. sylvaticus, and 28 as A. alpicola . We did not observe any double amplification and DNA sequencing confirmed species assignment obtained by the TaqMan assays. The method is implementable on different matrices (ear tissues, tail, and blood). It can be used on dead specimens or on alive animals with minimally invasive sampling, and given the high sensitivity, the assay may be also suitable for degraded or low-DNA samples. The method proved to work well to discriminate between the species analyzed. Furthermore, it gives clear results (amplified or not) and it does not require any postamplification handling of PCR product, reducing the time needed for the analyses and the risk of carryover contamination. It therefore represents a valuable tool for field ecologists, conservationists, and epidemiologists.

Abstract

Hantaviruses are a group of zoonotic viruses carried by rodents. Puumala virus (PUUV) and Dobrava virus (DOBV) are the causative agents of human hantavirus infections in Europe. Knowledge about hantavirus circulation in Italy is very scarce. West Nile virus (WNV) and Usutu virus (USUV) are emerging neuropathogenic flaviviruses, both endemic in most part of the Italian territories. To monitor the circulation of PUUV, DOBV, WNV, and USUV in natural environment in central Italy, we carried out serological surveillance in wild rodents. During this study, 90 animals were captured in forested areas of Abruzzo and Marche regions and tested with serological assays for the specific pathogens. Serological test provided no evidence of PUUV and DOBV circulation in the studied area. However, four rodents (Apodemus flavicollis) were found to be positive by WNV ELISA test. Two of them were confirmed as WNV by virus neutralization test.

Abstract

The maintenance of tick-borne disease agents in the environment strictly depends on the relationship between tick vectors and their hosts, which act as reservoirs for these pathogens. A pilot study aimed to investigate wild rodents as reservoirs for zoonotic tick-borne pathogens (Borrelia burgdorferi sensu lato (s.l.), Coxiella burnetii, Francisella tularensis, and Anaplasma phagocytophilum) was carried out in an area of Gran Sasso e Monti della Laga National Park (Abruzzi Region, central Italy), a wide protected area where, despite sporadic reports of infection in humans and animals, eco-epidemiological data on these diseases are still not available. Rodents were trapped and released at the capture site after the collection of feeding ticks and blood samples. In all, 172 ticks were collected; the most frequent species was Ixodes acuminatus (53%). Out of 88 tick pools, 11 resulted positive for C. burnetii and 13 for B. burgdorferi s.l.; the Borrelia afzelii genospecies was identified in one Ixodes ricinus tick collected from one Apodemus sp. rodent. Out of 143 blood samples, seven Apodemus spp. and five Myodes glareolus were positive for B. burgdorferi s.l. and two Apodemus spp. were positive for C. burnetii. All samples (ticks and blood) were negative for F. tularensis and A. phagocytophilum. This is the first report of B. burgdorferi s.l. in the environment for Abruzzi Region. Data on the presence of B. burgdorferi s.l. are similar to that observed in other Mediterranean countries. The present work is also the first report of C. burnetii in wild rodents in Italy. C. burnetii infection has been largely investigated in Italy in ruminant farms by serology and molecular methods, but information on ecology and on the wild cycle are still lacking. Further studies including genotyping should be performed and species-specific differences between wild rodent reservoirs of Q fever and Lyme disease agents should be investigated.

Abstract

Background: In the last decade, the availability of gene sequences of many plant species, including tomato, has encouraged the development of strategies that do not rely on genetic transformation techniques (GMOs) for imparting desired traits in crops. One of these new emerging technology is TILLING (Targeting Induced Local Lesions In Genomes), a reverse genetics tool, which is proving to be very valuable in creating new traits in different crop species., Results: To apply TILLING to tomato, a new mutant collection was generated in the genetic background of the processing tomato cultivar Red Setter by treating seeds with two different ethylemethane sulfonate doses (0.7% and 1%). An associated phenotype database, LycoTILL, was developed and a TILLING platform was also established. The interactive and evolving database is available online to the community for phenotypic alteration inquiries. To validate the Red Setter TILLING platform, induced point mutations were searched in 7 tomato genes with the mismatch-specific ENDO1 nuclease. In total 9.5 kb of tomato genome were screened and 66 nucleotide substitutions were identified. The overall mutation density was estimated and it resulted to be 1/322 kb and 1/574 kb for the 1% EMS and 0.7% EMS treatment respectively., Conclusions: The mutation density estimated in our collection and its comparison with other TILLING populations demonstrate that the Red Setter genetic resource is suitable for use in high-throughput mutation discovery. The Red Setter TILLING platform is open to the research community and is publicly available via web for requesting mutation screening services.
