Significance of Diagnostic Enzyme Detection
Serum enzyme tests have been used in clinical practice for a long time, such as increased amylase activity in serum and urine of patients with acute pancreatitis. In the 1930s, some scholars reported that the determination of serum lipase and alkaline phosphatase activities is helpful for the diagnosis of pancreatitis and bone diseases, respectively. After the 1950s, the application of serum ...

The Functions and Roles of Enzymes
Catalysis Enzymes are a class of biological catalysts. They govern many catalytic processes such as metabolism, nutrition, and energy conversion of organisms. Most of the reactions closely related to life processes are enzyme-catalyzed reactions. These properties of the enzyme enable the intricate process of material metabolism in the cell to proceed in an orderly manner, and to adapt material ...

When Respiratory Pathogen Metagenome Sequencing Meets Hybrid Capture Enrichment
Currently, the incidence of infectious diseases has increased globally, and the pathogens show a trend of diversification and complexity. Rapid and accurate pathogenic diagnosis, which enables early selection of sensitive anti-infective drugs or effective and targeted preventive and control measures, is the core of accurate prevention and treatment of infectious diseases. The epidemic of ...

Aerosol generating procedures and risk of transmission of acute respiratory infections to healthcare workers: a systematic review
Abstract Aerosol generating procedures (AGPs) may expose health care workers (HCWs) to pathogens causing acute respiratory infections (ARIs), but the risk of transmission of ARIs from AGPs is not fully known. We sought to determine the clinical evidence for the risk of transmission of ARIs to HCWs caring for patients undergoing AGPs compared with the risk of transmission to HCWs caring for ...

A Detailed Introduction to Exosome Proteomics
What are exosomes? Exosomes, a tiny membrane vesicle with a lipid bilayer structure, are secreted by most cells and are approximately 40-200 nm in diameter. exosomes are found in body fluids, including blood, saliva, urine and breast milk. exosomes of different tissue origins differ in content composition and function, and this difference is dynamically regulated by the extracellular matrix and ...

Classification and Function of Amylase
Amylase (AMS), also known as 1,4-α-D-glucanohydrolase, is a general term for enzymes that hydrolyze starch and glycogen. The main function of amylase is to break down starch to produce simple sugars such as fructose, maltose, glucose and dextrin. Amylases are also used in food and beverage processing and other industries. Classification of amylases 1. Alpha-amylase Alpha-amylase is mainly ...

Drawing into Bloodless Health Monitors
A team of scientists at the University of California, Berkeley developed a wearable sensor to monitor an individual’s health based upon their sweat. The sensor is constructed as a patch with a spiral-patterned microfluidic component where sweat samples can flow and be analyzed.[1] It has shown potential for monitoring sodium and fluid loss, and in some cases potassium.[1] The team would ...

New Study Findings about Glycoprotein PTGDS
Glycoprotein prostaglandin D2 synthase (PTGDS) is a member of the lipocalcitonin superfamily that plays a dual role in prostaglandin metabolism and lipid transport. PTGDS is involved in various cellular processes including solid tumorigenesis, but its role in tumorigenesis is paradoxical, and the significance of PTGDS in hematologic malignancies is not clear. The aim of this new study was to ...

Biochemical and Clinical Applications of Glucose Oxidase (GOD)
Glucose oxidase (GOD) is a typical oxidoreductase found in honey and molds such as Penicillium notatum. It can highly specifically catalyze the β-D-glucose reaction to generate gluconic acid, which has the function of converting glucose and removing oxygen. Since GOD can quantitatively generate hydrogen peroxide, it is widely used in the field of biochemistry and clinical examination as a ...

What Is Single-Cell Sequencing and How to Achieve It?
The cell is the basic unit of life. Most current studies on the human genome, cancer or other fields are still conducted from the population level, and the results are often the mean value of gene expression in cell populations or only represent information on the vital activities of numerically dominant cells, while failing to accurately reflect much of the information on cellular heterogeneity ...
