Summary
Elevated plasma homocysteine is a risk factor for vascular and eye diseases. Folic acid may help prevent stroke and cognitive decline, with ongoing research for retinal vascular disease prevention.
Area of Science:
- Ophthalmology
- Neurology
- Cardiovascular Medicine
Background:
- Elevated plasma homocysteine is a recognized risk factor for arterial disease, including retinal artery and vein occlusions.
- The efficacy of folic acid in preventing vascular disease progression remains under investigation.
- While secondary prevention of coronary artery disease with folic acid has shown limited success, primary prevention of stroke and cognitive decline appears promising.
Purpose of the Study:
- To evaluate the role of plasma homocysteine in vascular and eye diseases.
- To assess the effectiveness of folic acid supplementation in preventing vascular events.
- To discuss the implications of homocysteine reduction for retinovascular disease and public health initiatives like flour fortification.
Main Methods:
- Review of existing clinical trials and epidemiological data on plasma homocysteine levels and vascular disease.
- Analysis of outcomes from studies investigating folic acid supplementation for primary and secondary prevention of vascular and neurological conditions.
- Consideration of public health strategies, such as flour fortification, in relation to homocysteine levels and disease prevention.
Main Results:
- Plasma homocysteine is linked to arterial disease and occlusive events in the eye.
- Folic acid treatment has not definitively proven effective for secondary prevention of vascular disease, but shows promise in primary stroke and cognitive function prevention.
- Further data are needed, but homocysteine measurement and reduction are suggested for retinovascular disease.
Conclusions:
- Plasma homocysteine is a significant risk factor for vascular and ocular diseases.
- Folic acid supplementation shows potential for primary prevention of stroke and cognitive impairment, and is suggested for secondary prevention in retinovascular disease.
- Ongoing debates regarding flour fortification highlight the broader public health implications of managing homocysteine levels for vascular and neural tube defect prevention.

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:20Sulfur Assimilation
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
