What are antioxidants and their benefits ?






Quite often we hear about the benefits of antioxidants, their indispensability for maintaining a healthy body, their magical power to ward off cancer, Alzheimer etc. etc….  But most of the public do not have a clue as to what are these antioxidants. To know how the antioxidants work in our favor, we will also have to know about free radicals, which are being produced in our body.

What are antioxidants?

Antioxidants are chemical substances naturally found in Vitamin C, E, A, flavonoids, phenolic acids and beta-carotene in fruits, vegetables, nuts, pulses and cereals which inhibit oxidation and prevent cell damage. It is also found in synthetic form,  which is used as preservatives in processed food, but the effectiveness of synthetic antioxidants is not clear or established.  The antioxidant donates an electron to the free radical, thus neutralizing it into harmless. An antioxidant assist in countering oxidative stress, caused by free radicals.

What are free radicals?

Free radicals, also known as Reactive Oxygen Species (ROS) are chemical species that are naturally produced in our body during metabolism as a byproduct. However, some free radicals are produced in the body due to external factors like pollution, alcohol, smoking, medications, pesticides, infections, poor diet, toxins, radiation etc.  If free radicals are not controlled, it can attack the healthy cells of the body, resulting in oxidative stress posing danger to our health. Oxidation damages the cell membranes, cellular proteins and DNA. Preventing or fighting oxidative stress can go a long way in defending our body against tumors, cancer, heart problems, premature aging and scores of other body ailments. Deficiency of antioxidants will lead to piling up of free radicals in the body. A healthy dose of antioxidants will ensure that free radicals are deactivated before they start attacking the cells.

Sources of antioxidants

All the berry fruits, especially blueberry, blackberry,  cranberry and straw berry along with other fruits like apples, plums and grapes are loaded with the goodness of antioxidants. Phytochemicals, a form of antioxidant is found in tea and wine. Ascorbic acid, commonly known as Vitamin C is a very effective antioxidant present in most of the fruits and vegetables like capsicum, broccoli, and green leafy vegetables. Pulses like red kidney beans and black beans are also loaded with antioxidants. Vitamin E is fat soluble and found in abundance in nuts, fish, seeds, spinach, avocado, mango etc. Vitamin A is profoundly present in carrots, tomato, sweet potato, peaches and apples. Flavonoids have their presence in red wine, tea, soya and tomato and watermelon has lycopene content.

Role of antioxidants in pregnancy and infertility

Several studies conducted on pregnant women has indicated that a healthy dose of natural antioxidants do play a role in smooth pregnancy and in preventing miscarriages. Oxidative stress can be a reason for causing miscarriages, and some researches suggests that antioxidants may be helpful in preventing Pre-eclampsia (High blood pressure and protein in urine, during pregnancy can result in a fatal condition called Pre - eclampsia, which can cause preterm delivery.) Oxidative stress is also known to affect male fertility adversely by causing defective spermatogenesis. So infact, anioxidants can aid in improving the quality and quantity of the sperm.

Researchers have different opinions on whether, artificial supplements can give the same result as natural antioxidants.  So to be on the safer side, it is better to consume variety of  brightly colored fruits and vegetables, which will ensure a healthy dose of antioxidants.

Moringa (Drumstick) - key to your infertility woes and answer to a multitude of ailments



It won’t be an exaggeration to call Moringa Tree (Drumstick)  a “ MIRACLE TREE”. All the parts of the tree like, the leaves, bark, fruits, flowers,  sap, seeds, oil and even the root has medicinal or commercial utilities. Since ages, this has been utilized in Ayurveda to prevent and cure more than a hundred diseases and for enhancing general health and boosting immunity. I can go on and on and write pages about this precious tree, which is a powerhouse of goodness. But I will just give a brief account of the medicinal and nutritional properties of this plant

It is near to impossible to find a plant with as much Protein, Vitamin C,A, Pottassium, Calcium content as in Muringa leaves. It also has significant traces of Thiamine, Riboflavin, Niacin and Pyridoxine.

Muringa leaves  is known to stabilize blood pressure and sugar. It also seems to have diuretic and antiseptic properties, is  effective in curing headaches, fevers, infections, arthritis, anemia, parasite infection, ulcers and constipation.

The high protein content in muringa leaves make it an ideal food for vegetarians, as this is one vegetable, which can almost match the protein content in animal meat. Studies prove that the protein in muringa is better and higher than in soya. The amino acids essential for our body is present in these leaves. Even after drying, the leaves retain lot of its nutritional value, this along with the cheap and easy availability makes it ideal as a supplement for the malnourished  people in the third world countries.

In India, especially in the southern states, drumsticks and the leaves are revered as an aphrodisiac and is eaten to increase the sex libido, correct erectile dysfunction and improving the semen quality.  Male and female infertility is now a global challenge and  the tonic made out of flowers and leaves of  muringa is said to be a remedy for this crisis. It is also prescribed to the breastfeeding moms to enhance milk production.

The oil extracted from the seeds and roots also have scores of benefits. The unique property of this oil is that  it doesn’t turn stale even after years, hence is used  in perfumes, cosmetics and as lubricant  in machinery and watches.

Muringa is an easy to grow tree which requires minimum maintenance. In olden days, it was an asset to the South Indian kitchen backyards. The pesticide free fruits, leaves and flowers can augment the nutritional value of your food and keep you far away from illnesses.

   "All that man needs for health and healing has been provided by God in nature, the
                                 Challenge of science is to find it."

Is the future of Intra- Cytoplasmic Sperm Injection (ICSI) - PIEZO ICSI ?



When I attended the ACE 2015  conference, I was privileged to listen to an  interesting lecture by a Japanese embryologist. It was concerning a new technology called PIEZO  ICSI, wherein  vibration was used to puncture the egg instead of a needle, as employed in conventional  ICSI procedure. 

First let us understand the conventional ICSI procedure. ICSI is a process in which a sperm is directly injected into an egg. In current micromanipulators, sharp needle is used to forcibly penetrate the egg  through the zona pellucida (protecting cover of egg ) which causes considerable deformation of the zona or in simple terms creates a hole. This deformation may increase the internal pressure of the oocyte, (egg) induce the emission of ooplasm (cytoplasm inside the egg) from the oocyte after removal of the needle and may cause oocyte death.

Since the cytoplasm inside cell (egg)  has high extendibility, the inserted needle may not penetrate the cytoplasm. So the sperm should be injected after aspiration of the matter into the pippette, which is done by the embryologists. They aspirate little cytoplasm  and then only inject the sperm into the egg cell.

The first report on piezo-ICSI was published by Kimura and Yanagimachi (1995), who used mice as subjects. By means of this method, egg penetration can be achieved by voltage of piezoelectric elements. Similarly, after the cytoplasm is reached it can be punctured by applying one piezo pulse. 

So basically vibration is used to puncture the egg, there is no sharp needle, but only a smaller blunt needle. Therefore, chances of injuring the egg is less. Moreover, there is no need to aspirate the matter from egg contents to confirm entry, which again reduces the chances of harming the egg.

Currently, this method is being used in Japanese fertility centers, with higher success rate than conventional ICSI.  It is quiet expensive to maintain an ART lab, so upgrading with new equipment can be a challenge in the current Indian scenario, as ultimately the patients will have to  bear the brunt.
