Agriculture is typically divided into two main categories: crop farming and livestock farming. Crop farming involves the cultivation of crops such as grains, fruits, vegetables, and fiber crops, while livestock farming involves the raising of animals such as cattle, pigs, poultry, and sheep for meat, dairy products, and other products.
Aquaculture is the practice of farming aquatic organisms, such as fish, shellfish, and aquatic plants, in controlled environments, such as tanks, ponds, or ocean pens. Aquaculture is a rapidly growing industry that provides an increasing amount of the world’s seafood and other aquatic products, such as seaweed and algae.
Biobanking is the practice of collecting, storing, and managing biological samples, such as tissue, blood, urine, and DNA, for future research purposes. Biobanks are typically large repositories that contain samples from a variety of sources, including individuals, research studies, and clinical trials.
Biobanking plays an important role in medical research, as it provides a valuable source of biological materials that can be used to study diseases, identify biomarkers, and develop new treatments.
Biobanks can also be used for population-level studies to understand the genetic and environmental factors that contribute to various health conditions.
In a liquid biopsy, cancer cells and other biomarkers (like cell-free DNA) can be detected in the bloodstream, cerebrospinal fluid, urine, or other bodily fluids. The sample is typically analyzed using molecular techniques, such as DNA sequencing or PCR, to detect mutations or other abnormalities associated with cancer.
Molecular methods, such as polymerase chain reaction (PCR), are commonly used to detect viruses and other pathogens by amplifying and detecting specific nucleic acid sequences that are unique to the target organism. PCR can be performed on a wide range of sample types, including blood, tissue, and respiratory secretions.
Microbiome analysis is the study of the microorganisms that inhabit a particular environment, such as the human gut, skin, or soil. The microbiome is the collection of microorganisms, including bacteria, viruses, fungi, and other microbes, that live in and on the human body.
