Na v 1.7, Na v 1.8 and Na v 1.9 are found in the DRG and help mediate chronic inflammatory pain. [13] Na v 1.8 is an α-type channel subunit consisting of four homologous domains, each with six transmembrane regions, of which one is a voltage sensor. Structure of Na v 1.8, an α-type subunit with four homologous domains, each with six ...

Bone is a form of connective tissue found in the body, composed largely of hardened hydroxyapatite-containing collagen.In larger mammals, it is arranged in osteon regions. . Bone matrix allows mineral salts such as calcium to be stored and provides protection for internal organs and support for locomoti
In mammalian CA II, the active site consists of the following: a hard Lewis acid Zn +2 metal atom coordinated to His-94, -96, and -119 residues 109˚ apart from one another and a hydroxide ion (pKa=6.8; 120° in T d configuration, a hydrophobic pocket adjacent to Zinc-bound hydroxide consisting of by Val-143 at its base and Val-121, Trp-209 ...
The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight, [2] [3] with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. [4] There is substantial individual variation, [ 4 ] with the standard reference range for men being 1,180–1,620 g (2.60–3.57 lb) [ 5 ] and for women ...
This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based.
In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads. They reach their peak of development in humans, where they may number 200–400/cm 2 of skin surface. [5] [6] They produce sweat, a merocrine secretion which is clear, odorless substance, consisting primarily of water. These are present from birth.
The most common collagen is type I collagen which makes up 90% of all collagen. It is found in all dermal layers at high proportions while type IV collagen is only found at the basement membrane of the epidermal junction. [6] Despite their differences in commonality, they are both strongly altered during aging or cancer progression. [citation ...
