Case study To illustrate and evaluate the functionality of rprimer, two assays targeted at norovirus GI were designed. Assay A: RT-qPCR for quantitative detection of norovirus GI The first task was to design a broadly reactive RT-qPCR assay for quantitative detection. For this, we decided to use the ‘ambiguous’ primer…

Sepsis patients and healthy controls A total of 62 sepsis patients (male/female: 32/30; mean age, 52.3±4.9 years) who were admitted to Minhang Hospital, Fudan University between March 2018 and March 2020 were enrolled in the study. In addition, 62 healthy controls (male/female: 32/30; mean age, 52.4±4.8 years) who were at…

Hi, in this video we’ll show you how to explore the m6A and m5C epitranscriptomes upon viral infection. To start the experiment, you’ll need 50 million cells for the noninfected and 50 million for the infected condition. In order to obtain a high quality dataset upon analysis, you’ll need to…

ABSTRACT Background: Circular RNAs (circRNAs), which have broad posttranscriptional regulatory potencies, are involved in the pathogenesis of fibrotic diseases and are promising diagnostic biomarkers and therapeutic targets. However, their specific roles in renal fibrosis remain…

Introduction Hepatic fibrosis (HF) is a pathological phenomenon produced in the process of long-term damage and repair in the liver [1,2]. During the formation of HF, hepatocytes are damaged by various factors, such as chronic liver disease, and excessive intake of alcohol, and secrete a variety of cytokines [3]. Subsequently,…

Single guide ribonucleic acid (sgRNA) molecules are produced by discontinuous transcription, in which viral RNA-dependant RNA polymerase pauses early negative-sense RNA synthesis and then jumps to the other end of the genome. The specifics of this process are still not fully understood. Since sgRNAs can play an important role in…

Genomic data The foundational resource for this study was a dataset of 40,107,925 nuclear SNPs sequenced from a worldwide sample of 532 DBM individuals collected in 114 different sites based on our previous project15. DNA was extracted from each of the 532 individuals using DNeasy Blood and Tissue Kit (Qiagen,…

I’m a data scientist trying to branch out into more bioinformatics/genetics. My tutorial is counting spike-ins, but his explanation was over my head: 1 – AnnData and Preprocessing spike-ins | Kaggle ” Because this is smartseq2 data, we may have spike-ins. An RNA spike-in is an RNA transcript of known…

CHICAGO – Canadian startup BugSeq Bioinformatics has devised a method of detecting pathogens via metagenomic nanopore sequencing that the company says is more accurate and sensitive than PCR and microbial cultures. Notably, the technology does not need to target specific pathogens like PCR and microbial culture tests must. The firm…

RT-qPCR really high fold change 0 Hello everyone, I am getting really high gene fold change values for one of the gene of interest i.e. ~70000 folds. I am using SYBR green as a polymerase. Is this normal ? If something is wrong, how can I improve my experiment and…

Significance During the aging process, senescent cells secrete inflammatory factors, causing various age-related pathologies. Thus, controlling the senescence-associated secretory phenotype (SASP) can tremendously benefit human health. Although SASP seems to be induced by the alteration of chromosomal organization, its underlying mechanism remains unclear. Here, it has been revealed that noncoding…
