The importance of nucleic acids in controlling life processes is well known. Under the suitable conditions, DNA molecules are responsible for replication of themselves and acts as templates for RNA synthesis in transcription. In translation, RNA molecules control protein synthesis and thus various metabolic activities in living cells. All these processes are monitored by sequences of bases in polynucleotide chains. Nucleosides consist of a sugar group and a heterocyclic nucleobase that bound to ...

What is cystic fibrosis?Cystic fibrosis (CF) is a rare genetic disorder that affects the lungs, digestive system, and other organs. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a protein that regulates chloride ions transport across cell membranes. These mutations cause the CFTR protein to be either absent or not function properly, leading to the buildup of thick, sticky mucus in the lungs, pancreas, and other organs. Treatment o...

The diagnosis and treatment of rare diseases have long been a daunting challenge due to their complex and often undefined nature. However, with recent advancements in technology, specifically in the realm of genomics, whole genome sequencing (WGS) has emerged as a powerful tool that has revolutionized the diagnosis and management of rare diseases. This groundbreaking technique offers hope to countless individuals and their families who have suffered from the uncertainties and lack of answers ass...

In the field of scientific research, understanding and studying emotion-related behaviors in animals plays a crucial role in advancing the knowledge of the human brain and mental health. Animal models can help researchers better comprehend animal behaviors, and rodent models in particular have become important objects for understanding the mechanisms of emotional behaviors and exploring new treatments for emotion-related disorders including anxiety, depression, and stress. With their remarkable ...

The ability to overexpress genes in microorganisms has revolutionized the field of synthetic biology. Gene overexpression involves the production of large quantities of target proteins by increasing the transcription and translation of the gene of interest. This technique has been applied in the engineering of microorganisms to produce a wide range of products, including biofuels, chemicals, and biopharmaceuticals. There are several strategies for gene overexpression in strain engineering. One c...

Aging is a biological process that occurs in each of us as individuals and is accompanied by a variety of changes. At the molecular level, DNA methylation occurs, a process in which a methyl group is covalently bonded at the cytosine 5 carbon position of a genomic CpG dinucleotide, and the association between DNA methylation and aging has been extensively studied and their close correlation has been found.DNA methylation is an epigenetic modification that plays a key role in many aging-related b...

Strong base anion (SBA) exchange resin is one type of ion exchange resins containing quaternary ammonium groups on the microsphere surfaces. The SBA resin shows an excellent physical and chemical stability, which is capable to exchange the different anion under a wide range of pH value. SBA resins are ideal for removing certain anionic contaminants and can be regenerated with salt.SBA resins are usually divided into two classes according to their functional groups. Type I SBA resins are aminated...

Laboratory equipment is a general term for the various instruments, containers and other tools needed for operation, synthesis, and analysis in various laboratories. The equipment helps researchers to observe, test, experiment or analyze data to confirm the authenticity or rationality of scientific hypotheses. According to the scope of application, laboratory equipment can be divided into general equipment and specialized equipment.General laboratory equipment includes freezers, incubators, shak...

DNA Methylation Age AccelerationAge acceleration can be defined as the difference between the DNA methylation age and the actual age, or as the residual resulting from regressing the DNA methylation age on the actual age. In comparison, the latter definition is more accurate and practical. We can determine the rate of biological aging based on the specific value of the DNA methylation age acceleration, with positive values indicating faster than expected aging and negative values the opposite.DN...

Silica-based vectors are attractive as gene transfer vehicles due to their high stability, safety, and ease of structural and surface modification. A variety of silica-based vectors for gene delivery have been reported, including silica nanotubes (SNT), silica sheets, and silica NPs (solid (non-porous) silica NPs and porous silica NPs). Among these, silica NPs have been extensively investigated by researchers as carriers with many useful and attractive properties.Several reports have been publis...
