Once a suitable genomic fragment is chosen (Step 1), the exons and introns of the fragment can be inserted and amplified, along with the flanking constitutive exons and introns of the original gene, by PCR. The p...

Minigene Determining the complete set of components involved in splicing presents many challenges due to the abundance of alternative splicing, which occurs in most human genes, and the specificity in which splicing is carried out "in vivo". Splicing is distinctly conducted from cell type to cell type and across differ...

Minigene One specific example of a splicing error causing an endocrine disease that has been studied using minigenes is a type of growth hormone deficiency called isolated growth hormone deficiency (IGHD), a disease that results in growth failure. IGHD type II is an autosomal dominant form caused by a mutation in the i...

Minigene Minigenes have been used by several researchers to help understand the regulatory components responsible for mRNA splicing of the TAU gene. Cancer is a complex, heterogeneous disease that can be hereditary or the result of environmental stimuli. Minigenes are used to help oncologists understand the roles pre-m...

Sulfur (pharmacy) Sulfur is used in pharmaceutical skin preparations for the treatment of acne and other conditions. it acts as a keratolytic agent and also kills bacteria, fungi, scabies mites and other parasites. Chemically, it is the naturally occurring octasulfur (S). Precipitated sulfur and colloidal sulfur are us...

Sulfur (pharmacy) Sulfur's keratolytic action is also mediated by HS; in this case, the hydrogen sulfide is produced by direct interaction with the target keratinocytes themselves.

Biomaterials (journal) Biomaterials is a peer-reviewed scientific journal covering research on and applications of biomaterials. It is published by Elsevier and the editor-in-chief is Kam W. Leong (Columbia University). The journal was established in 1980. The journal is abstracted and indexed in: According to the "Jou...

Beevers–Lipson strip Beevers–Lipson strips were a computational aid for early crystallographers in calculating Fourier transforms to determine the structure of crystals from crystallographic data, enabling the creation of models for complex molecules. They were used from the 1930s until computers with enough power beca...
