Tracking the hologenome dynamics in aquatic invertebrates by the holo-2bRAD approach.

The "hologenome" concept is an increasingly popular way of thinking about microbiome-host for marine organisms. However, it is challenging to track hologenome dynamics because of the large amount of material, with tracking itself usually resulting in damage or death of the research object. Here we show the simple and efficient holo-2bRAD approach for the tracking of hologenome dynamics in marine invertebrates (i.

The Immunomodulation Role of Vaginal Microenvironment On Human Papillomavirus Infection.

Background: Evidence suggests the role of the vaginal microbiome and microenvironment in the immunity state. The human papillomavirus (HPV) infection is widely dependent on the healthy vaginal microenvironment. Hence, this study aimed to investigate the role of the vaginal microenvironment in the rate of high-risk HPV (hr-HPV) infection.

Study on the Effect of B-Ultrasound NT Scan in Early Pregnancy Combined with Serum Screening in Early and Middle Pregnancy for Down Syndrome.

Objective: Down syndrome (DS), also known as trisomy 21 syndrome, is a common and most harmful congenital chromosomal genetic disease. This study is aimed at exploring the effect of B-ultrasound NT scan in early pregnancy combined with serum screening in early and middle pregnancy for Down syndrome.

Methods: A total of 168 pregnant women who were diagnosed and treated in the obstetric clinic of our hospital from January 2019 to December 2021 were selected as the research objects.

Durable, cost-effective and superhydrophilic chitosan-alginate hydrogel-coated mesh for efficient oil/water separation.

Hydrogels with low-adhesive superoleophobicity are ideal candidates for modifying filtration substrates to achieve efficient and antifouling oil/water separation. However, there are still some unfavorable factors hindering their practical application, including expensive raw materials, complex fabrication process, poor stability and durability. In this work, a durable, cost-effective and superhydrophilic chitosan-alginate (CS-ALG) hydrogel coated mesh was developed by a facile, two-step dip-coating method for efficient oil/water separation in hypersaline environments.

Sequencing-Based Transcriptome-Wide Targeted Genotyping for Evolutionary and Ecological Studies.

Transcriptome-wide targeted genotyping is highly attractive for evolutionary and ecological studies but, until recently, accomplishing this goal presented a major technical barrier for the study of non-model organisms. Our group has recently developed a high-throughput targeted genotyping approach (called HD-Marker) based on the high specificity and accuracy of oligo extension-ligation assays that facilitates the design of assays tailored to meet specific genotyping needs. HD-Marker allows for targeted genotyping of over 10 000 genes in a single tube, with strikingly high capture rate (98%-99%) and genotyping accuracy (97%-99%).
