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.

What is Optical Microscopy?

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before the 18th century and is still in use today.

Optical Microscopy Techniques

The techniques used in optical microscopy are important to ensure that a sample can be viewed as clearly as possible. This will provide information about its microscopic appearance.

Limitations of Optical Microscopy

Optical microscopy is a very useful technique to examine the appearance of a sample with greater detail, but there are some limitations that provide a boundary to its use in practice.

Emerging Trends in Proteomics

Proteomics is a branch of molecular biology that focuses on the protein expression within an organism or cell. It is a comprehensive study with high throughput of a specific proteome to identify particular cellular processes.

Macromolecules: Polysaccharides, Proteins and Nucleic Acids

Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The interactions between the various components of a cell and its water content is key to biological chemistry.

Gut Microbiota

The human body is colonized with a dense community of more than 100 trillion microbes, most of which live in the gut. The “good” microbes in the gut aid the digestion of food, regulate the immune system, make certain vitamins and protect against harmful bacteria.

Skin Microbiota

The skin microbiota is the term used to describe the collection of microorganisms that live on our skin. More specifically, it refers to the genomes of all these microbes including bacteria, fungi, protozoa, viruses, and mites living.

Oral Microbiota

The mouth is colonized by a rich and diverse microbial community made up of more than 700 different species of bacteria, certain species of fungi, and even protozoa.

Microbiome and Disease

The microbiome is the collective term used to refer to all of the microbes found in or on the human body and more specifically, the genomes of those microbes.

Human Microbiome

The human microbiome refers to the spectrum of microbes (microbiota) that colonize humans. More specifically, it refers to the microbial genomes of all the bacteria, fungi, protozoa, and viruses that are found inside or on the body.

Human Microbiome Project (HMP)

The human body is colonized by thousands of microbial species, together referred to as the microbiome. Humans have about ten times more microbial cells than human cells, and the number of genes contained in the microbiome is more than 100 times greater than the number found in the human genome.

Achievements of the Human Microbiome Project

The human microbiome refers to the entire community of microorganisms that live on or in the human body. More specifically, it refers to all of the genes in these microbes, which include bacteria, fungi, protozoa, and viruses.

What is Metagenomics?

Metagenomics is the study of microbes in their natural living environment, which involves the complex microbial communities in which they usually exist. The study examines the genomic composition of an entire organism, including each of the microbes that exist within it.
