There are several types of genetic sequences variations (polymorphisms) in the human genome: repeated polymorphisms, insertions and deletions. However the majority of the DNA sequence variations in the human genome is in the form of SNPs which are persistent single changes, substitutions or variants of a single base in at least a population and with a frequency of more than 1% referred as allel...

An elusive biological cycle in the eye the daily disposal and regeneration of the end tips of photoreceptor cells has been captured in images for the first time in a living human eye. Photoreceptors are light-sensitive cells responsible for initiating vision. This glimpse into the inner workings of the eye will help scientists better understand, prevent and manage major eye diseases that affect...

Introduction A better understanding of the pathophysiological processes occurring in “retinal aging” and age-related macular degeneration (AMD) has been achieved in recent years, leading to the emergence of new treatments and consequent long-term improvements in the patients quality of life. AMD is one of the leading causes of severe, irreversible vision impairment in developed countries, in in...

Cryopumping is of interest to both fusion reactors and particle accelerators since it can provide the following features: (1) very high pumping speed ever a large pressure range; (2) very low equilibrium pressure; (3) very large capacity; (4) cleanliness; (3) ability to store ehe pumped species on the cryosurface for later recovery; (6) neither high voltage nor magnetic field is required, which...

AMd is recognized as one of the most serious environmental problem in the mining industry. the problem of acid mine drainage (AMd) has been present since mining activity began thousands of years ago. Mining activity has disrupted the hydrology of mining areas so badly that it is extremely difficult to predict where water would eventually re-emerge. its causes, treatment have become the focus of...

Theme 3 of the HRAC-programme focuses on long-term use of natural resources with regard to agriculture, cattle, marine organisms, metals, housing and trade. However, people do not usually live only on crops, cattle or marine products. Many people combine cultivation with herding, fishing, gathering and/or hunting. The combination of such activities in a production system is influenced by the en...

This issue of IOVS presents a novel strategy to develop treatment for nonexudative age-related macular degeneration (dry AMD) that derives from the natural, protective response of RPE cells to cellular stress. Oxidative stress is implicated in AMD pathogenesis and results in the upregulation of small heat shock proteins that act as molecular chaperones to prevent cellular apoptosis and minimize...
