Purpose Of Review: Plasma metagenomic next-generation sequencing (mNGS) enables detection of microbial cell-free deoxyribonucleic acid (mcfDNA) in blood without the need for culture or organism-specific primers. Here, we review clinical performance, methodological variability, and real-world application of plasma mNGS for infectious disease diagnosis in immunocompromised hosts (ICHs).
Recent Findings: Plasma mNGS has rapidly gained attention as a novel diagnostic tool for infections in ICHs, offering broad-range pathogen detection from a noninvasive blood sample.

Despite the development of messenger ribonucleic acid (mRNA) vaccines for the infectious novel coronavirus 2 (SARS-CoV-2), further research on test methods is required to ensure their quality as well as rapid and effective approval for release to the market. During the current national lot release testing, identity tests cannot be conducted on other products using primers, probes, and in-house reference materials provided by the manufacturer and specific to one vaccine, because their sequences do not match. When key reagents and reference materials are dependent on the manufacturer in this way, difficulties in national lot release approval-which serves as an additional step for the government to verify product quality-arise if the manufacturer does not provide them.

Background And Aims: Chinese old garden roses are major contributors in the genetic development of modern roses. The RoKSN gene is associated with continuous flowering in roses and is proposed to have originated from Chinese wild roses. However, the wild roses that are implicated in the breeding of Chinese old garden roses and the origin of the RoKSN locus remain unidentified.

Enzymatic deoxyribonucleic acid (DNA) synthesis (EDS) is an environmentally friendly approach capable of generating longer and more complex sequences than chemical synthesis, making it a promising next-generation technology for high-throughput single-stranded DNA production. However, precise sequence control at high throughput remains a key challenge. Here, we present a novel electronically controlled deprotection chemistry (ECDC) integrated with a hydrogel-primer modification system on-chip for efficient multiplexed EDS.

In zebra finches and other birds, males are the homogametic sex (ZZ) while females are heterogametic (ZW), and females are distinguished by the presence of specific sequences on the female-specific W chromosome. However, when only a single W locus is analyzed, lack of a PCR product in a sample could potentially arise from genetic variation or technical failure of the amplification, leading to false identification of female samples as males.
