WHY CORNER

Why do we stop growing after a certain stage?

When certain aquatic plants keep growing throughout their life, then why do we terrestrial animals stop growing? Well, a simple explanation is that that all animals, including humans, have evolved such that they stop growing at a size that balances energy efficiency and their competitive needs as they struggle to survive.

In humans, genes determine the growth pattern and height that one attains. Growth is said to occur when cells called chondroblasts multiply, adding cartilage to the ends of bones. Cells called osteoblasts then deposit calcium and other minerals in the cartilage and turn it into new bone tissue. As the deposition of calcium and minerals goes on, bones become longer and you grow taller. Toward the end of puberty, your body produces lots of oestrogen and this inhibits chondroblast proliferation thus slowing down the addition of new cartilage to the ends of your bones. When all the cartilage in the active growth area is calcified, you stop growing.

The overproduction or underproduction of certain hormones (bio-chemicals released in our body) or the inability to respond to them can affect growth, making it above or below normal. Gigantism is caused by the overproduction of the pituitary growth hormone, whereas severe short stature is often caused by the body’s inability to respond to this and other growth hormones.

Another interesting theory to explain this issue is that terrestrial animals have to support their weight without any help. Therefore, we have been designed to stop growing to protect our bodies from becoming bigger than we can manage.

According to space researchers, if you travel into space, you will  grow irrespective of your age. Although the effect is temporary, you can actually grow by as much as eight centimetres while in orbit, they say. This is due to reduced gravitational force acting on your body. As a result, the spinal column stretches out a bit thus making one taller. This phenomenon is also visible when you are asleep. If you sleep horizontally, you will actually be a little taller in the morning since gravity is unable to compress your spinal column until you stand up.

Meditation

Meditation(Mental Exercise)

According to Swami Vishnu Devananda, meditation is  .a continuous flow of perception or thought, just like the flow of water in a river.” A practice wherein there is constant observation of the mind, meditation brings awareness, harmony and natural order into life. It helps you dig deep into your inner self to discover the wisdom and tranquility that lie within.

Principles of Meditation

The basic points to be kept in mind in practicing meditation are :

1.Have a special place and specific time for meditation. Try doing it daily.

2.Choose a time when your mind is not clouded with worries.

3.Sit up straight with your back, neck and head in one line. Facing north or east.

4.Condition your mind such so as to remain quiet for the duration of your meditation session.

5.Regulate your breathing. Start with 5 minutes of deep breathing. Then gradually slow it down.

6.Follow a rhythmic breathing pattern – inhale and exhale.

7.Initially let your mind wander. It grows more restless if you force to concentrate.

8.Then slowly bring it to rest on the focal point of your choice.

9.Hold your object of concentration at this focal point throughout your session.

10.Meditation happens when you reach a state of pure thought. Even while retaining an awareness of duel self.

Followed diligently you will soon be able to attain a super-conscious state.

Tips on Concentration

1.At the outset, it is hard to keep your attention to keep focussed on one object.

2.So it is better to start off by limiting your field of concentration to a category of objects.

3.Choose your objects with care e.g. any four flowers, fruits, trees…etc. You must feel at ease with what you choose.

4.After concentrating on one, you can move on to the next, if & when your mind starts wandering.

This style of meditative exercise will help you control your mind down to a finer focus, teaching you the principle of single point concentration.

Meditative Postures:-

1.Close your ears with thumbs.

2.Cover your eyes with your index finger.

3.Close your nostrils with your middle fingers.

4.Press your lips together with your remaining fingers.

5.Release the middle fingers gently to inhale and exhale while you meditate
Frontal & Nasal Gazing:-

1.Gaze at a point between your eyebrows, seat of the ‘Third Eye’ or at the tip or your nose.

2.This would improve your level of concentration. At the same time, strengthening your eye muscles. Nasal gazing has a positive effect on the central nervous system.

3.Remember not to strain your eyes. Start with one minute of gazing and then slowly build it up to ten minutes.

Candle Gazing

CLICK  & SEE
1.Place a candle at eye-level in a darkened, draught-free room.

2.Close your eyes and hold an after-image of the bright flame.

3.The practice steadies the wandering mind, leading you to focus with pin-point accuracy.
Meditation is an ancient technique to revive your weary soul and help you deal effectively with stress, and helps you rediscover a sense of profound peace and inner calmness.

Meditation is a state of consciousness that can be understood only on a direct, intuitive level.

Ordinary experiences are limited by time, space, and the laws of causality, but the meditative state transcends all boundaries.

Meditation is a natural state of consciousness that isn’t learned, any more than one learns to sleep. When the mind becomes one-pointed and steady, it will naturally go beyond the normal mundane awareness into the state referred to as Meditation.

How to Meditate ?

 

Please sit down comfortably, spine erect, head straight. Hands on the top of the knees or in the lap, wherever comfortable. Eyes closed. For a few moments become aware of the whole body from the top of the head to the toes. Experience open space within the body.

Imagine the whole body to be in the form of flame. First see the symbol of the flame in front of the closed eyes; see the flame in chidakasha.

Gradually experience the radiating light of the flame spreading throughout the body, purifying the body, illuminating each and every part of the body. The whole body becomes one with the light. Each and every cell of the body becomes one with the light. There is no part of the physical body where darkness can exist. Each and every cell of the body is infused with the light. Experience the whole body in the form of pure light.

At first this is a process of imagination, but with concentration, the feeling develops. The body then responds to that feeling and one can actually see the radiance internally. Try to experience and feel that radiance now within yourself. See yourself filled with light internally and surrounded by light externally. Continue to observe yourself in the form of light and mentally repeat the mantra OM with every inhalation and exhalation. With total awareness repeat the mantra internally. Do not miss a single breath and repeat the mantra OM with every inhalation and exhalation. Merge yourself completely in the repetition of the mantra and the experience of light within. Now inhale deeply and chant OM three times.

Anise

[amazon_link asins=’B003AYEHNE,B01F5IB4TC,B071WQTK9J,B000J5XPX0,B000EWMI5O,B072P6PCD3,B06XBCMN54,B01E7MTNFE’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’b6a778ce-7e67-11e8-9c7b-c7379d8ea66a’]

Botanical Name:Pimpinella anisum.
Family:
Apiaceae
Genus:
Pimpinella
Species:
P. anisum
Kingdom:
Plantae
Order:
Apiales

Habitat:
Anise is native to  Eastern Mediterranean or Western Asia.

Synonyms: Anisum vulgare (Gaertn.), A. officinarum (Moench.), Anise, Anisum, Anisi fructus, common aniseed

Parts used: Fruits (sometimes incorrectly called “seeds”).
Cultivated : Southern Europe, North Africa, Near East, China, Pakistan, Mexico, Chile, USA
Taste/smell:Sweet and very aromatic. A similar fragrance to that of cicely.( licorice-like, sweet)

Etymology: The spice gained its Latin name anisum as a result of confusion with dill, known in Greek as an?son. Names of anise in virtually all European languages are derived from anisum.
The Sanskrit name shatapushpa means “one hundred flowers” and refers to the flower cluster. The Hindi name saunf properly denotes fennel, of which anise is incorrectly thought to be a foreign variety. To distinguish anise clearly from fennel, the specialised terms patli saunf “thin fennel” or vilayati saunf “foreign fennel” are often used. Some languages refer to the sweetness of anise, e.g. Greek glykaniso “sweet anise”, or name anise as a sweet variant of other spices, e.g. Indonesian jinten manis and Arabic kamun halu “sweet cumin” (a name sometimes also used in English). Arabic has another, similar name habbu al-hulwa “sweet grains”. The Portuguese term erva doce “sweet herb” may denote anise, fennel or sweetleaf (stevia rebaudiana).
The genus name pimpinella is Late Latin for “narrow-ribbed fruit”.
Major Uses: pastries, candies, liquors

Description:

Anise, Pimpinella anisum, is an herbaceous annual plant in the family Umbelliferae grown primarily for its fruits which are used as a spice. The plant has a grooved stem and alternately arranged leaves. The lower leaves are round with a toothed edge and petioles which can be between 4 and 10 cm (1.6–3.9 in) in length. The upper leaves are feathered and become progressively shorter towards the top of the plant. The aniseed plant produces umbels of white flowers and an oval, flattened, hairy fruit with a single seed. Anise can reach a height of 45–60 cm (17.7–23.6 in) and is an annual plant, surviving only one growing season. Anise may also be referred to as aniseed and originates from the Mediterranean.

Several spices have been called anise. The native of Egypt, Pimpinella anisum, is anise seed or aniseed, while China is the source of Illicum verum, star anise. In the past, dill, caraway and fennel seeds were confused with anise seed.
Useful Parts: The seeds have been used widely in cooking, and are popular in spicy cakes. The oil of anise  is often used in artificial licorice, and gives its distinctive taste to liqueurs such as anisette and raki. Anise is used in many processed foods and in cough medicines, and is often included in pet foods for the flavor it imparts.
Edible  Uses:In Western cuisine, anise is mostly restricted to bread and cakes although fruit products are occasionally aromatised with anise. In small dosage, anise seeds are sometimes contained in spice mixtures for sausages and stews. Their main applications are, however, anise-flavoured liqueurs, of which there are many in different Mediterranean countries including rak? in Turkey, ouzo in Greece and pernod in France. In many cases, oil of anise is partially or wholly substituted by oil of star anise in these products.

In the East, anise is less known and both fennel and star anise are more easily available and more popular. Anise may substitute for fennel in North Indian recipes, but it is a less suitable substitute for star anise in Chinese foods.
Anise appears occasionally in Mexican recipes, but native anise-flavoured herbs (Mexican tarragon and Mexican pepper-leaf) are more commonly used. Anise is an acceptable substitute for both, although tarragon is even better.
Several plants generate an aroma comparable to that of anise. Within the apiaceae (parsley) family, fennel and cicely copy the aroma of anise perfectly and chervil and dill also resemble anise, although their fragrance is less pure. In Far Eastern cuisines (India, Iran and Indonesia), no distinction is made between anise and fennel and the same name is usually given to both of them. In the Philippines star anise is very popular and is referred to as “anise” for short.

Constituents:
As with all spices, the composition of anise varies considerably with origin and cultivation method. These are typical values for the main constituents.

*Moisture: 9-13%
*Protein: 18%
*Fatty oil: 8-23%
*Essential oil: 2-7%
*Starch: 5%
*N-free extract: 22-28%
*Crude fibre: 12-25%
*Essential oil yielded by distillation is generally around 2-3% and anethole makes up 80-90% of this.

Medicinal Properties: Over the centuries, anise has been reported to have numerous medical benefits, but there is no evidence that it offers any pharmacologic benefit. It is thus a flavorful digestive spice that may be soothing, stimulating or carminative (relieving gas) in different individuals, and it is a popular taste in drinks, confections and simple proprietary medicines.

Anise is a carminative and an expectorant. It is also a good source of iron. One tablespoon of anise seeds sprinkled on cookies, bread or cake provides 16% of the RDA for a woman and 24% of the RDA for a man. A 1990 study tested the effect of certain beverage extracts on the absorption of iron. The results showed that anise was the most effective of the extracts tested in promoting iron absorption. The authors recommended offering this as a preventive agent to iron deficiency anemia. To make a carminative tea that may relieve intestinal gas, crush 1 teaspoon of anise seeds per cup of boiling water. Steep for 10-20 minutes and strain. Drink up to 3 cups a day. In a tincture, take  1 teaspoon up to three times a day. Diluted anise infusions may be given cautiously to infants to treat colic. For older children and people over 65, begin with low-strength preparations and increase strength if necessary. Some people simply chew the anise seeds. Early English herbalist Gerard suggested anise for hiccups. It has also been prescribed as a milk promoter for nursing mothers and as a treatment for water retention, headache, asthma, bronchitis, insomnia, nausea, lice, infant colic, cholera and even cancer. America’s 19th century Eclectic physicians recommended anise primarily as a stomach soother for nausea, gas, and infant colic.

Modern uses: Science has supported anise’s traditional use as a treatment for coughs, bronchitis, and asthma. According to several studies the herb contains chemicals (creosol and alpha-pinene) that loosen bronchial secretions and make them easier to cough up. Another chemical (anethole) acts as a digestive aid. Anise also contains chemicals (dianethole and photoanethole) similar to the female sex hormone estrogen. Scientists suggest their presence probably accounts for the herb’s traditional use as a milk promoter and may help relieve menopausal discomfort. One report shows that anise spurs the regeneration of liver cells in laboratory rats, suggesting a possible value in treating hepatitis and cirrhosis. While there are no studies that support using anise to treat liver disease in humans, anise looks promising in this area.

Other Miscellaneous Uses:
*In the 1860s, American Civil War nurse Maureen Hellstrom used anise seeds as an early form of antiseptic. This method was later found to have caused high levels of toxicity in the blood and was discontinued shortly thereafter.

*According to Pliny the Elder, anise was used as a cure for sleeplessness, chewed with alexanders and a little honey in the morning to freshen the breath, and, when mixed with wine, as a remedy for asp bites (N.H. 20.72).

*The Biblical “anise” mentioned in some translations of Matthew 23 is dill (A. graveolens), rather than this plant.

*In 19th-century medicine, anise was prepared as aqua anisi (“Water of Anise”) in doses of an ounce or more and as spiritus anisi (“Spirit of Anise”) in doses of 5–20 minims.

*In Pakistani and Indian cuisines, no distinction is made between anise and fennel. Therefore, the same name (saunf) is usually given to both of them. Some use the term patli (thin) saunf or velayati (foreign) saunf to distinguish anise from fennel, although Gujarati has the term anisi or Sava.

*In the Middle East, water is boiled with about a tablespoon of aniseed per teacup to make a special hot tea called yansoon. This is given to mothers in Egypt when they are nursing.

*Builders of steam locomotives in Britain incorporated capsules of aniseed oil into white metal plain bearings, so the distinctive smell would give warning in case of overheating.

*Anise can be made into a liquid scent and is used for both drag hunting and fishing. It is put on fishing lures to attract fish.

*Anise is frequently used to add flavor to mu’assel, particularly the double apple flavor.

*Anise is one of the three odors used in K9 Nosework.

Historical View :
Oil of anise possesses the same aromatic, carminative, and stimulant properties as anise fruits, and as already noticed is commonly preferred to them as a medicine, and is alone official in the British Pharmacopoeia.

New hope for patients of Parkinson disease

[amazon_link asins=’1491283157,1934938262,981466989X,B01HRBU9ZA,B00AVLXQEK,0199543712,B00UV9TE7A,1421410761,3319084755′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ee1eef8d-2d92-11e8-bfdb-33302acc68a5′]

It is news that would gladden the hearts of the world’s most notable Parkinson disease (PD) sufferers – actor Michael J Fox and boxing champion Muhammad Ali.

Two weeks ago Deep Brain Stimulation (DBS) surgery was performed on a 71-year-old woman at Wockhardt Hospitals in Mumbai, providing much needed relief to the patient and her family members.

The elderly woman was suffering from Parkinson  for the last 10 years. During the operation, an electrode was implanted in her brain to selectively inhibit a group of cells responsible for the symptoms.

Dr. Paresh Doshi, 43, who performed the crucial operation said, “Surgery should be considered in patients of Parkinson disease when they have uncontrolled tremors and have drug related side effects as seen in advanced Parkinson disease. It is also helpful for patients who have either left their jobs or who are at the risk of leaving their job due to the disease.”

According to Dr Doshi, though the selection of the right patient is extremely important there is no age limit to perform the surgery. He also points out that the surgery is safe and has virtually no side effects. In fact, the risks of complications are less than two per cent.

The elderly woman (name withheld) who underwent surgery is recovering well. “She suffered from severe hallucinations and altered sleep patterns as well as extreme stiffness of limbs. Now she has started walking. But the psychological impact of the disease is still there and it takes a while for the patient to adjust,” says Dr Doshi.

The patient is discharged from hospital ten days after surgery. The follow-up examination is conducted once in three months and then once at the end of the year. After that, once a year is enough. “I have overseas patients who have not come to me for the last 2-3 years and they are doing well,” informs Dr Doshi.

The post-operative care is minimal except that at airports, the patient needs to avoid the metal detectors as they have pace makers installed that sends current to the brain. The pace makers last for 5-6 years.

The surgery is still out of bounds for the common man because it costs around Rs 6.5 lakh inclusive of the implants.

Till date there is no cure found for Parkinsons. Blood samples and laboratory tests have failed to detect the disease. The diagnosis is almost purely based on medical history and neurological examination. Since the doctors don’t know what causes the disease, they are helpless in providing cure. “It’s like diabetes and hypertension. We still don’t have the cure for them,” laments the doctor.

As for the belief that the disease is caused because a parent might have it, the doctors believes that there are only 4 to 5 percent chances of such a possibility.

There is hope for those who have suffered very deeply from the disease. “We have even operated upon 10 doctors in the past. And they have all gone back to work. There is no permanent cure but the surgery controls the degeneration and the patient can perform normal functions majority of the time. However, they continue to remain highly dependent on their caretakers, as they cannot become fully normal,” according to the doctors.

The world is still looking for cure though it can at least be controlled now. “The cure could come from stem cell,” hopes Dr Doshi, who is the only Asian in the International Task Force for Movement Disorders Surgery.

The disease afflicts persons within the age of 50-70 years. But Dr Doshi says he knows of patients who are as young as 40-year-old, which is nearly 25 per cent of people who have fallen prey to the disease.

Once afflicted with this disease, the doctors cannot prevent it from progressing. In extreme cases, one has to go for expensive surgery. But the medicines are not life threatening. If medicines do not suit a patient, doctors can discontinue it and switch to another line of treatment.

Even abroad very few centres perform the surgery. Among the developed countries, England has around 50 centres but only six or seven have the facility to perform this surgery. France which has the most advanced centres, only one-fifth of neurosurgical centres have the expertise, informs Dr Doshi.

Explaining the reason for such a dismal picture Dr Doshi responds, “A doctor has got to be young, requires huge amount of dedication, patience and training. And there can be very few who will have that kind of time. The kind of care and adequate attention required in this disease is normally not needed in treating other ailments.”

Dr Doshi learnt about this surgery from Professor Benabid. Now he is confident that in India DBS has reached an advance level of precision.

“Three years ago even the Food and Drug Administration of the US gave its approval,” he claims.

Since 1998, Dr Doshi has taken up as many as 110 cases, which by now, seems to be the largest in the world. However in India, there are not too many centers performing DBS, just one or two in India namely in Trivandrum and Delhi.

In India, about 8-10 patients per 10,000 fall to prey to the disease. Among Parsis the number is 350. But now there is more awareness about the disease. In Mumbai, the doctor has encountered quite a large number of cases of Parkinsons.

The disease is characterised by lack of movement, tremors, unsteady gait and stiffness. The disease hits the central nervous system that often impairs the sufferer’s motor skills and speech.

Osteoporosis

X-ray showing a the proximal portion of a frac...
Image via Wikipedia

What It Is

Osteoporosis, derived from the Latin for porous bones, is a progressive condition that diminishes the mass (mineral content) of bones and weakens their structure, making them highly susceptible to fracture. Half of postmenopausal women, and up to one in eight older men, will suffer a fracture as a result of osteoporosis. No single measure is sufficient to prevent the disorder, but a combination of supplements and lifestyle changes can be effective in limiting damage.

Osteoporosis is a disease in which bones become weaker and more likely to break. And what’s worse, you may not even feel it happening.

How do your bones get weaker? Your bones are living tissue. They constantly renew themselves with cells that build bone and cells that take away bone. With osteoporosis, your bones lose density, making them weaker and more likely to fracture.

……...

To get an inside look at the effects of osteoporosis, the pictures  below is to explain the difference between healthy bones and osteoporotic (or weak) bones.

Because your bones are living tissue,they are constantly renewing themselves.However when the cells are taken away bone work faster than the cells that built bone, that can cause bone loss. And over the time,it can lead to osteoporosis.

…………………>normal_cells_image.Between healthy bones and osteoporotic bone, there is osteopenic bone (low bone mass). This occurs which bone mass is just below normal, but not quiet osteoporotic. And that means your bones are weakening and loosing mass- a condition that may eventually lead to                           osteoporosis.>.cell_image2- Osteopenia.When the normal bone is viewed under microscope, parts of it  look like a honeycomb. But if you have osteroporosis, the space inside the honeycomb become longer. That means you are loosing bone density.and you get osteoporosis->cell_image3-Osteoporosis

What Causes It

The decline in estrogen after menopause is directly related to the dramatic rise of osteoporosis in older women. This hormone assists the body in absorbing calcium and keeps the bones strong. (Older men experience osteoporosis as well; but because they have denser bones, bone loss is generally less severe.) Lack of regular weight-bearing exercise is another risk factor, as is a diet low in calcium and other nutrients necessary for optimal bone production. Your risk of osteoporosis is also higher if you’re small boned (white and Asian women tend to be small boned), underweight, or postmenopausal; if you have a family history of osteoporosis; or if you’ve taken steroids or anticonvulsants for long periods.

Symptoms

The first sign can be dramatic: a severe backache or a fracture (often of the spine, hip, or wrist.
Other classic symptoms include a gradual loss of height accompanied by the initially subtle development of a stooped posture (dowager’s hump).
Dental X rays may detect early osteoporosis by revealing bone loss in the jaw.
