Evolution of the brain developmental plan: Insights from agnathans.
In vertebrate evolution, the brain exhibits both conserved and unique morphological features in each animal group. Thus, the molecular program of nervous system development is expected to have experienced various changes through evolution. In this review, we discuss recent data from the agnathan lamprey (jawless vertebrate) together with available information from amphioxus and speculate the se...
متن کاملCloning and characterization of mannose-binding lectin from lamprey (Agnathans).
The recognition of pathogens is mediated by a set of pattern recognition molecules that recognize conserved pathogen-associated molecular patterns shared by broad classes of microorganisms. Mannose-binding lectin (MBL) is one of the pattern recognition molecules and activates complement in association with MBL-associated serine protease (MASP) via the lectin pathway. Recently, an MBL-like lecti...
متن کاملTuberculosis & traditional medicine: fighting the oldest infectious disease, using the oldest source of medicine
It is believed that tuberculosis has been killing human beings for over 4000 years. Several reports exist of ancient Egyptian mummies having signs of tubercular decay in their bodies. After the discovery of powerful anti-TB drugs such as streptomycin, isoniazid and rifampin during 1940-70s, it was thought that TB would be gone from the face of the earth, but tuberculosis still remains one of th...

متن کاملTuberculosis and Traditional Medicine: Fighting the Oldest Infectious Disease Using the Oldest Source of Medicines
Tuberculosis (TB) is the oldest documented infectious disease. Fragments of the spinal column from Egyptian mummies from 2400 B.C. shows definite pathological signs of tubercular decay. The term phthisis (consumption) appears first in Greek literature. Hypocrates identified phthisis as the most widespread disease of the times around 460 B.C. Exact pathological and anatomical descriptions of the...
