The Montreal Cognitive Assessment (MoCA) is a widely used screening assessment for detecting cognitive impairment. [1] It was created in 1996 by Ziad Nasreddine in Montreal , Quebec . It was validated in the setting of mild cognitive impairment (MCI), and has subsequently been adopted in numerous other clinical settings.
Collagen is also abundant in corneas, blood vessels, the gut, intervertebral discs, and the dentin in teeth. [3] In muscle tissue, it serves as a major component of the endomysium. Collagen constitutes 1% to 2% of muscle tissue and accounts for 6% of the weight to skeletal muscle. [4] The fibroblast is the most common cell creating collagen in ...
Type I collagen is the most abundant collagen of the human body, consisting of around 90% of the body's total collagen in vertebrates. Due to this, it is also the most abundant protein type found in all vertebrates. Type I forms large, eosinophilic fibers known as collagen fibers, which make up most of the rope-like dense connective tissue in ...

Pig skin especially shares similar epidermal and dermal thickness ratios to human skin: pig and human skin share similar hair follicle and blood vessel patterns; biochemically the dermal collagen and elastin content is similar in pig and human skin; and pig skin and human skin have similar physical responses to various growth factors.

This gene encodes one of the chains for type ...
This mutation substitutes the amino acid cysteine for the amino acid arginine at position 134 in the protein made by the gene. (The mutation can also be written as Arg134Cys.) The altered protein interacts abnormally with other collagen-building proteins, disrupting the structure of type I collagen fibrils and trapping collagen in the cell.
Collagen alpha-1(VII) chain is a protein that in humans is encoded by the COL7A1 gene. [5] It is composed of a triple helical, collagenous domain flanked by two non-collagenous domains, and functions as an anchoring fibril between the dermal-epidermal junction in the basement membrane. [ 6 ]
