Hepatitis A virus (HAV) was detected in two samples of mixed frozen berries linked to Italian hepatitis A outbreak in April and September 2013. Both viruses were fully sequenced by next-generation sequencing and the genomes clustered with HAV complete genomes of sub-genotype IA with nucleotide identities of 95–97 %. 相似文献

Objective
To develop a multi-step workflow for the isolation of circulating extravillous trophoblasts (cEVTs) by describing the key steps enabling a semi-automated process, including a proprietary algorithm for fetal cell origin genetic confirmation and copy number variant (CNV) detection.Methods
Determination of the limit of detection (LoD) for submicroscopic CNV was performed by serial experiments with genomic DNA and single cells from Coriell cell line biobank with known imbalances of different sizes. A pregnancy population of 372 women was prospectively enrolled and blindly analyzed to evaluate the current workflow.Results
An LoD of 800 Kb was demonstrated with Coriell cell lines. This level of resolution was confirmed in the clinical cohort with the identification of a pathogenic CNV of 800 Kb, also detected by chromosomal microarray. The mean number of recovered cEVTs was 3.5 cells per sample with a significant reverse linear trend between gestational age and cEVT recovery rate and number of recovered cEVTs. In twin pregnanices, evaluation of zygosity, fetal sex and copy number profiling was performed in each individual cell.Conclusion
Our semi-automated methodology for the isolation and single-cell analysis of cEVTS supports the feasibility of a cell-based noninvasive prenatal test for fetal genomic profiling. 相似文献73.

Mate guarding is a male strategy to gain access to receptive females but often results in antagonistic interactions between
the sexes because of different costs/benefits of guarding. In addition to social, morphological, and physiological parameters,
the type of mating system should also affect the strength of the conflict and thus the guarding duration. Specifically, when
compared to females, self-compatible hermaphrodites might have reduced benefits of outcrossing. We investigated mate guarding
in dioecious (co-presence of females and males) and androdioecious (co-presence of hermaphrodites and males) branchiopod crustaceans.
Both sexes in androdioecious systems should shift their guarding times to lower values relative to dioecious systems because
(1) androdioecious males are present in lower percentages than dioecious males and thus encounter rates with receptive mates
are relatively greater for them; and (2) hermaphrodites should have low incentive to incur high costs of mate guarding, having
the alternative of self-fertilization, and thus should be highly eager to resist. While females preferred short guarding times,
when allowed to control the guarding duration (males tethered), dioecious males did not increase their guarding duration when
females (treated with muscular relaxant) could not resist, in contrast to what has previously been found for androdioecious
males. This indicates that hermaphrodites are more willing to resist mate guarding than females. The among-species comparisons
supported our hypotheses: compromised guarding times were significantly lower in androdioecious than in dioecious species.
The introduction of a parameter (mating system) not previously investigated in mate guarding models resulted in a powerful
test of mate guarding theory, adding a valuable contribution to our understanding of intersexual conflict. 相似文献
