Senile cataract: a review on free radical related pathogenesis and antioxidant prevention

Archives of Gerontology and Geriatrics

Abstract

Glutathione metabolism plays an essential role in the homeostasis of the lens. Thus, it is not surprising that experimental depletion of this substance leads to a process of lens disorganization similar to senile cataract and that in all types of irreversible cataract there is a decrease in the glutathione content of the lens. Therefore, it may be useful in preventive geriatrics to raise the glutathione concentration of the lens and, since glutathione monoethyl ester can cross the capsule and membranes of the lens, administration of this compound may be the treatment of choice. This could be complemented by long-term administration of small doses of acetylsalicylic acid, in the early stages of the development of cataracts. The data also suggest that, in the 'high lactose absorbers', diets deprived of lactose (in addition to antioxidant administration) may play a role in protecting against cataract development and may even reverse some of the early changes that occur in cataractous lenses. The present review provides a justification for detection of cataract risk factors (high lactose absorption and low antioxidant protection in blood) as well as for preventive and palliative treatment of cataracts by administration of physiolog...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
