Hirudin is a naturally occurring peptide in the salivary glands of blood-sucking leeches (such as Hirudo medicinalis) that has a blood anticoagulant property. [2] This is essential for the leeches' habit of feeding on blood, since it keeps a host's blood flowing after the worm's initial puncture of the skin.
Rhodopsin, also known as visual purple, is a protein encoded by the RHO gene [5] and a G-protein-coupled receptor (GPCR). It is a light-sensitive receptor protein that triggers visual phototransduction in rod cells.
Ractopamine (/ r æ k ˈ t ɒ p ə m aɪ n,-m iː n /) is an animal feed additive used to promote leanness and increase food conversion efficiency in farmed animals in several countries, but banned in others.
Ivermectin is an antiparasitic drug. [7] After its discovery in 1975, [8] its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. [9] Approved for human use in 1987, [10] it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis.
Microchimerism is the presence of a small number of cells in an individual that have originated from another individual and are therefore genetically distinct. This phenomenon may be related to certain types of autoimmune diseases although the responsible mechanisms are unclear.
Likewise, Viagra shouldn’t be combined with antiretroviral drugs used to treat HIV/AIDS, as it can cause an increased concentration of sildenafil in the body. Breastfeeding women shouldn’t ...
A Human Genome Equivalent (HuGE) review in 2004 looked at studies of the connection between genetic mutations affecting leptin regulation and obesity. They reviewed a common polymorphism in the leptin gene (A19G; frequency 0.46), three mutations in the leptin receptor gene (Q223R, K109R, and K656N) and two mutations in the PPARG gene (P12A and ...
