Placental Microbiome

The placenta is an organ attached to the womb lining that supplies a developing fetus with nutrients and oxygen, as well as removing fetal waste and secreting hormones. The microbiome refers to the trillions of microorganisms that reside within or on the human body. Microorganisms influence a number of bodily processes such as metabolism and digestion and are suspected to play a role in important illnesses such as diabetes and obesity

Microarray Applications

The microarray is a very recent development in the field of biotechnology. Scientists are now able to understand the gene functions of any organism by tracking down thousands of genes and their products at the same time, with the help of this technology.

What is Ultraviolet Microscopy?

Ultraviolet (UV) microscopy is a type of light microscopy that utilizes UV light to generate a magnified image of the sample being analyzed. As a result of the shorter wavelength of UV light than visible light, it is possible to view samples with greater magnification and resolution.

Uterine Microbiome

Interest in the microbiome of the reproductive tract has been growing over recent years. Studies of vaginal and placental microbiomes have shown associations between these microbiomes and obstetric outcomes and it is plausible that the uterine microbiome is also associated with these outcomes.

Enzyme Mechanisms

Enzyme mechanisms of catalysis play many important roles in the functioning of a healthy body. An enzyme may exist as a multi-subunit complex or it may be associated with a cofactor such as adenosine triphosphate (ATP)

What is Digital Holographic Microscopy?

Digital holographic microscopy (DHM) is a type of microscopy that combines digital holography with microscopy to allow transparent cells to be visualized with classic cell culture plates.

Types of Microarray

Microarray or biochip is a lab-oriented microscope slide that is usually made of glass, silicon chip, or nylon membrane. It is a 2D array (sometimes 3D) whose surface is provided with thousands of minute pores in defined positions.

GFP-tagging in Fluorescence Microscopy

Green Fluorescent Protein (GFP) was first isolated from the jelly fish, Aequorea victoria. The protein consists of 238 amino acid residues that fluoresce green when exposed to UV light. The gene for GFP was successfully inserted into E.coli bacteria in 1994 and the Nobel Prize in Chemistry 2008 was jointly awarded to Osamu Shimomura, Martin Chalfie and Roger Y. Tsien for the discovery and development of GFPs. They are commonly used as a reporter of expression in biology.

DNA Replication and Repair

DNA replication and repair are critical processes that ensure the correct genetic material of a biological system is carried on. DNA continually undergoes a process of replication and division and errors can sometimes occur in the process. It is essential for the biological system to have a mechanism in place to detect and repair these errors.

Amino Acid Metabolism

Amino acid metabolism is an important process that occurs within the human body to assist in numerous biological reactions. This article will cover the role of glutamate, transamination reactions, and various types of amino acids such as glycogenic, ketogenic, and mixed amino acids.

What is Glycolysis?

Glycolysis is a series of reactions that helpextract energy from glucose. This is an ancient pathway of metabolism that is present in the majority of living organisms today. It is the foundation of both aerobic and anaerobic cellular respiration. It takes place in the cytosol of a cell and is the foundation of both aerobic and anaerobic cellular respiration.

Using a Scanning Probe Microscope

There are several techniques that can be used to operate a scanning probe microscope. The choice of which method to use will depend on the situation at hand and the purpose.

Enzyme Kinetics

Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its catalytic mechanism, role in metabolism, factors that impact its activity, and mechanisms of inhibition.

DNA microarray

The microarray is a recently developed technology used in cancer research and in the pharmacological treatment of other diseases such as oral lesions. In this technology, a microscope slide (normally a 2D array made of glass, silicon chips, or nylon membrane) printed with thousands of minute spots in definite positions is used.

Amino Acids and Protein Sequences

Each protein or peptide consists of a linear sequence of amino acids. The protein primary structure conventionally begins at the amino-terminal (N) end and continues until the carboxyl-terminal (C) end. The structure of a protein may be directly sequenced or inferred from the sequence of DNA.

Types of Electron Microscopes

There are several different types of electron microscopes, including the transmission electron microscope (TEM), scanning electron microscope (SEM), and reflection electron microscope (REM.) Each of these types of the electron microscope will be described in more detail in this article, including the benefits and disadvantages of each.

Advantages and Disadvantages of Electron Microscopy

Electron microscopy is a useful technique that allows us to view the microscopic structure of specimens at a high resolution. However, it is not without disadvantages and requires significant resources to purchase and maintain the device at optimal function.

Protein Structure and Function

The structure of protein sets the foundation for its interaction with other molecules in the body and, therefore, determines its function. This article will cover the structural principles of proteins and how these can have an effect on the function of the protein.

Lung microbiome

Over the past decade, culture-independent microbial investigation techniques have led to an improved understanding of the complete set of microbes that live on and within the human body. This set of human-associated microbes is collectively known as the microbiome.

How Does the Diet Impact Microbiota?

The microbial population in the colon is a major source of many essential chemical factors which drive normal or abnormal metabolism. There are ten times as many microbes in the colon as there are cells in the human body.
