Antioxidants can prevent or slow cell damage caused by free radicals. Free radicals are unstable molecules that the body produces as a reaction to environmental and other pressures. They can increase the risk of inflammation and various health issues.
They are sometimes called “free-radical scavengers.”
The sources of antioxidants can be natural or artificial. Certain plant-based foods are thought to be rich in antioxidants. Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient.
The body also produces some antioxidants, known as endogenous antioxidants. Antioxidants that come from outside the body are called exogenous.
Free radicals are waste substances produced by cells as the body processes food and reacts to the environment. If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function. Free radicals are also known as reactive oxygen species (ROS).
Factors that increase the production of free radicals in the body can be internal, such as inflammation, or external, for example, pollution, UV exposure, and cigarette smoke.
Oxidative stress has been linked to heart disease, cancer, arthritis, stroke, respiratory diseases, immune deficiency, emphysema, Parkinson’s disease, and other inflammatory or ischemic conditions.
Antioxidants are said to help neutralize free radicals in our bodies, and this is thought to boost overall health.
Antioxidants can protect against the cell damage that free radicals cause, known as oxidative stress.
Activities and processes that can lead to oxidative stress include:
mitochondrial activity
excessive exercise
tissue trauma, due to inflammation and injury
ischemia and reperfusion damage
consumption of certain foods, especially refined and processed foods, trans fats, artificial sweeteners, and certain dyes and additives
smoking
environmental pollution
radiation
exposure to chemicals, such as pesticides and drugs, including chemotherapy
industrial solvents
ozone
Antioxidants are molecules capable of reducing the causes or effects of oxidative stress. Oxidative stress can be caused by environmental factors, disease, infection, inflammation, aging (ROS production). The body produces some endogenous antioxidants, but dietary antioxidants may provide additional line of defense. Flavonoids & other polyphenolics, Vitamins C & E, and Carotenoids are the most common dietary antioxidants. Many herbs and botanicals also contain antioxidants.
Any molecule containing one or more unpaired electrons. These unpaired electrons readily form free radical molecules which are chemically reactive and highly unstable.

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. Antioxidants are substances that may protect your cells against free radicals, which may play a role in heart disease, cancer and other diseases. It may scavenge the free radical or neutralize the free radical.

Oxidation is a chemical reaction that transfers electrons from a substance to anoxidizing agent Oxidation
reactions can produce free radicals. In turn, these radicals can start chain reactions.
Antioxidants terminate the chain reactions by removing free radical intermediates, and inhibit other oxidation
reactions. They do this by being oxidized themselves, so antioxidants are often called as reducing agents such
as thiols, ascorbic acid or polyphenols.
Antioxidants are widely used as ingredients in dietary supplements and have been investigated for the
prevention of diseases such as cancer, coronary heart disease and even altitude sickness.
Antioxidants are our first line of defense against free radical damage, and are critical for maintaining optimum
health and wellbeing. The need for antioxidants becomes even more critical with increased exposure to free
radicals. Pollution, cigarette smoke, drugs, illness, stress, and even exercise can increase free radical exposure.
Because so many factors can contribute to oxidative stress, individual assessment of susceptibility becomes
important. Many experts believe that the Recommended Dietary Allowance (RDA) for specific antioxidants
may be inadequate and, in some instances, the need may be several times the RDA. As part of a healthy lifestyle
and a well-balanced, wholesome diet, antioxidant supplementation is now being recognized as an important
means of improving free radical protection. Damage to cells caused by free radicals is believed to play a central
role in the aging process and in disease progression. The present paper Reviews the Role of LYCOTENFORTE
Capsules in maintaining optimum health and wellbeing.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

ANTI OXIDANTS)
• Antioxidants are chemical
substances that are needed by
our body to slow down or to
stop the oxidation process.
This substance protects
body cells from damage by
free radicals and is
considered as a defensive
line against diseases.
Our bodies are capable of
producing antioxidant substances,
but as we grow old, this ability
decreases Therefore, we need to get antioxidants from food.

• Oxidation can be seen when foods are exposed to the air.
• This process causes fruits such as apples and bananas to become brown
when left exposed to the air.
