    Abstract:

    Three patients with alopecia areata were observed to have spotty absence of t4e whiteness of the lunulae of their nails. This was ascribed to defects in the tongue of matrical epithelium which lies under the nail plate and accounts for the lunula. An analogy is drawn with Wickham's striae.

    lncRNA - Long Non-coding RNAs

    In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
