A genome-wide association study is what the National Institutes of Health call "a study of common genetic variation across the whole human genome with the goal of finding genetic links to observable traits."Even though family linkage studies and studies with tens of thousands of gene-based SNPs measure genetic variation across the genome, the National Institutes of Health definition requires a good density and selection of genetic markers to capture a large proportion of common variants in the study population, measured in enough people to give enough power to detect variants with modest effects.

Regulation of gene expression is fundamental to linking genotypes with phenotypes. RNAs shape complex gene expression networks, which drive biological processes. An in-depth understanding of the underlying mechanisms of how to govern these complex gene expression networks is vital for the treatment of complex diseases such as cancer. Hybridization-based microarrays are used to allow the simultaneous monitoring of expression levels of annotated genes in cell populations. However, genome-wide approaches have proven to provide more valuable insights into transcriptomes. These next- or third-generation sequencing platforms allow the rapid and cost-effective generation of massive amounts of sequence data. The RNA profiling by utilizing high-throughput sequencing technologies is known as RNA-seq.
Small RNAs are important functional molecules in organisms, which have three main categories: microRNA (miRNA), small interfering RNA (siRNA), and piwi-interacting RNA (piRNA). They are less than 200 nt in length and are often not translated into proteins. Small RNA generally accomplishes RNA interference (RNAi) by forming the core of an RNA-protein complex (RNA-induced silencing complex, RISC). Small RNA sequencing, an example of targeted sequencing, is a powerful method for small RNA species profiling and functional genomic analysis. Here, we present the guidelines for bioinformatics analysis of small RNA sequencing.

The principle of ion exchange resin is the process that ion exchange resin removes the salt in the solution.
How Do Ion Exchange Resins Work? Structure Ion exchange resins are composed of three parts: the insoluble three-dimensional space network polymer skeleton, the ion functional group connected to the skeleton, and the exchangeable ion pore with opposite charges on the functional group. Polymer skeleton: It is composed of cross-linked polymers, such as cross-linked polystyrene, polyacrylic acid, etc. Ion exchange group: It is connected to the polymer skeleton and has ionic functional groups with exchangeable ions, such as -SO3Na, -COOH, -N(CH3)3Cl, etc., or polar non-ionic functional groups, such as -N(CH3)2, -N(CH3)H, etc. Pore: It is the pore in the polymer structure (gel pore)…
With the introduction and popularization of Mini-LEDs with smaller LED light-emitting crystals, quantum dot technology will quickly become the standard choice for liquid crystal displays.
Since its commercial use in 2015, although liquid crystal displays equipped with quantum dot technology have significantly improved in display color gamut and rendering effects, their popularity is far below expectations. On the one hand, the maturity of quantum dot technology is not good, and the stability and cost of products are relatively high; on the other hand, the price of models using quantum dot display technology is relatively high, which hinders the popularization of technology. With the introduction and popularization of Mini-LEDs with smaller LED light-emitting crystals, quantum dot technology…

Capacity, cost, and performance. Three of your top data storage priorities? No wonder, and it’s the same for most organisations across the healthcare sector. The volume of data healthcare organisations produce is in overdrive. That, added to legal requirements to store that data for very long periods of time, impacts the size of your data centre, how far your budget will stretch, and how quickly data can be moved. This growth is a major challenge for many data storage vendors today: requirements for storage capacity and longevity continue to expand with no signs of slowing down in sight. Enter DNA storage. A technology promising to store millions upon millions of gigabytes in just a few particles, for thousands of years.

Changes in the number of proteomes in a cell have a big effect on many aspects of life. For example, the occurrence and development of many diseases are often accompanied by abnormal expression of certain proteins. Quantitative proteomics is the accurate quantification and identification of all proteins expressed in a genome or all proteins in a complex mixed system. At present, quantitative proteomics technology is mainly divided into labeling strategies and non-labeling strategies, in which the labeling strategies are divided into in vivo labeling (such as SILAC), and in vitro labeling (such as iTRAQ, TMT).

Post-translational modification of proteins is a covalent process that a protein goes through during or after translation. This process changes the properties of a protein by adding one or more amino acid residues to a modification group or by proteolytically cutting the group, which is an important step in the expression of protein biological functions. Post-translational modifications of biological proteins greatly increase the types and functions of protein structures. This process regulates the cell cycle and protein transcription and affects epigenetics.
