What do Synodontis catfish eat?

How can you tell if a synodontis is male or female?

The spermatoduct can be seen on the caudal side. Females also have a clearly visible papillae but this is more rounded and the oviduct is on the opposite side to the male’s spermatoduct. Most species of medium/large Synodontis can be sexed using this method but it should be noted that most species take 2 years or more to reach sexual maturity.

What is fish used for in medicine?

In medicine, FISH can be used for diagnosis, evaluation of prognosis, and evaluation of remission of a disease such as cancer. FISH can be used to detect diseased cells more easily than standard cytogenetic methods.

What is the purpose of using fish microscopy?

Fluorescence microscopy can be used to find out where the fluorescent probe is bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification.

How is fish used in cytogenetics?

Cytogeneticists use FISH to identify genetic abnormalities related to cancer, as well as other diseases and conditions. In addition to being used for the purpose of detection, FISH can provide supplementary information that can be used to predict a patient’s response to certain treatment types.

Why is fish used to study chromosomes?

It is an important tool for understanding a variety of chromosomal abnormalities and other genetic mutations. Different from most other techniques used for chromosomes study, FISH has no need to be performed on cells that are actively dividing, which makes it a very versatile procedure.

What is the difference between fish and MedicineNet?

MedicineNet does not provide medical advice, diagnosis or treatment. See additional information. FISH: Fluorescence in situ hybridization, a molecular cytogenetic technique that tags genetic material with fluorescent molecules.

What is the use of fish microscopy in DNA fingerprinting?

Fluorescence microscopy can be used to find out where the fluorescent probe is bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification. FISH can also be used to detect and localize specific RNA targets ( mRNA,…

What is the purpose of using fish?

FISH is used by examining the cellular reproduction cycle, specifically interphase of the nuclei for any chromosomal abnormalities. FISH allows the analysis of a large series of archival cases much easier to identify the pinpointed chromosome by creating a probe with an artificial chromosomal foundation that will attract similar chromosomes.

What is the application of FISH technique in plant chromosomes?

This technique, initially developed for mammalian chromosome, was first applied to plant chromosomes by Schwarzacher et al. (1989) and Yamamoto and Mukai (1989). FISH has been used to detect 18S.26SrRNA and repeated DNA sequences in plant chromosomes such on Aegilops, Hordeum, Oryza, Arabidopsis, Brassica, soybean, and barely chromosome.

Is fish more efficient than Cytogenetics in detecting residual malignant cells?

The results of this study showed that FISH is more efficient than conventional cytogenetics in detecting residual malignant cells. For chromosomal rearrangements FISH is an extremely sensitive method which not only verifies but also interprets with more precision the findings of classical cytogenetics.

What is the application of fish in cancer research?

FISH can also be applied to such research applications as gene mapping or the identification of novel oncogenes or genetic aberrations that contribute towards various cancers. FISH is based on DNA probes annealing to specific target sequence of sample DNA.

What are the advantages of FISH techniques for chromosomal abnormalities?

A particular advantage of FISH techniques is the possibility to also study chromosomal aberrations in nondividing cells, which is useful for the visualization of chromosomal aberrations directly in cytological preparations and tissue sections.

What is the focus of the fish study?

FISH also can identify chromosomal abnormalities in leukemias, including chronic lymphocytic leukemia (CLL) cells, some of which are associated with aggressive forms of the disease. Patients with more aggressive forms of CLL may need urgent treatment, while those with less aggressive forms may only require observation.

Can I give my Fish medicine?

As already noted; genetically weak or old/geriatric fish often do not benefit from medications/treatments, even in hospital or bath treatments. Sometime medications might actually fo more harm such as lowering red blood cell count or damaging kidneys in an already weak fish.

Can I give my Aquarium Fish tetracycline?

As well, the mix of medication and volume depends on the disease you are trying to treat and the inhabitants of your tank. Tetracycline, NEVER mix Tetracycline with any other medication. The reason for this is that it is a very harsh treatment and lowers the red blood cell count in your aquarium fish.

What is the function of the FISH technique?

FISH is a powerful technique that labels a known chromosome sequence with DNA probes attached to fluorescent dyes, thus enabling visualization of specific regions of chromosomes by fluorescent microscopy.

What is an example of a fish test for cancer?

Examples of FISH Tests for Cancer. Although the FISH test is often used to analyze genetic abnormalities in breast cancer, it also can provide important information about many other types of cancer. In the diagnosis of bladder cancer, for example, FISH testing of urinary cells may be more reliable than a standard test that looks for abnormal cells.

What is fish prenatal testing?

FISH Prenatal Testing Explained. FISH, or Fluorescence In Situ Hybridization, is a diagnostic prenatal test which looks for a few common chromosomal abnormalities. A fluorescent dye is used to visualize and map genetic material in cells. FISH is usually performed with the same genetic material gathered for testing during CVS or amniocentesis.

What is the fish used for in biology?

Moreover, the FISH is used in the study of three-dimensional chromosomal structure and organization. It is practiced for monitoring the success of transplantation, for example, bone marrow transplantation. Illustration of two different color probes hybridized at two different locations on a chromosome.

What is the purpose of using the fish method?

FISH has been used to answer questions related to structure, mutation, and evolution of not only individual chromosomes but also entire genomes. FISH has served as an important tool for chromosome identification in many plant species.

Are FISH techniques the future of routine biopsy for hematological malignancies?

In consequence, FISH techniques are likely to play an increasing role in the future of diagnosis and assessment of routine biopsies from hematological malignancies. Supplementary Material Supplemental Material:

How can fish help in the fight against cancer?

Improved aetiology through techniques such as FISH may be crucial in the fight against cancer, with the knowledge acquired effectively directed towards the research and development of better treatment strategies to benefit the sufferers of diseases based on these genetic aberrations.

Is FISH test still used?

However, FISH remains useful for some tests. FISH may also be used to study comparisons among the chromosomal arrangements of genes across related species. What is FISH used for?
