Extend Your Life Span with this Antioxidant

In 2003, research showed that resveratrol, a powerful polyphenol and anti-fungal chemical, was able to increase the lifespan of yeast cells. The results ignited flames of hope for an anti-aging pill. According to the findings, resveratrol could activate a gene called sirtuin1, which is also activated during calorie restriction in various species.

Since then studies in nematode worms, fruit flies, fish, and mice have linked resveratrol to longer lives. Other studies with only resveratrol have reported anti-cancer effects, anti-inflammatory effects, cardiovascular benefits, anti-diabetes potential, energy endurance enhancement, and protection against Alzheimer’s.

Resveratrol is found in grapes and red wine, and has particularly been associated with the so-called ‘French Paradox‘ — the low incidence of heart disease and obesity among the French, despite their relatively high-calorie diet and levels of wine consumption.

Head In The Clouds

Shadow
Image by premasagar via Flickr

Cloud Meditation.
When people use the phrase “head in the clouds,” they usually refer to a mental state that appears to be drifting rather than concentrating. For this reason, putting our heads in the clouds can be a wonderful meditation tool. Whether puffy and white or tinted with the colors of dawn and dusk or shades of gray, those vaporous sky dwellers can remind us of so many things about life and about ourselves.

For this meditation, we can find a physical place to relax and look upward, or we can look to the skies from within our imaginations. Directing our thoughts to the endless of expanse of sky that clouds inhabit, we feel our souls expand to reach beyond any seeming limitations. Following the clouds, we are free to unleash our imaginations. We may choose to merely drift along with them for a time, enjoying their distanced perspective on the world. Or we can look for messages in their fantastical shapes, or feel the joy of bounding between their immense billowy puffiness. However we interact with them, we do so from a peaceful place. Clouds drift above the hustle of the world below, knowing they belong to another realm that cannot be affected by its frenzy, reminding us that peace is always available to us. By directing our vision beyond the ordinary, clouds also remind us of the illusion of appearances. While appearing to be solid, their vapor and mist appear like cotton balls ! from below, giving little indication of the heights they reach. Sometimes they may cast shadows, leaving us in shade, but like life’s difficulties clouds change shape and move onward, revealing the shining sun, twinkling stars, and blue sky that are behind them.

When a ray of light breaks through the clouds, their dramatic filtering only makes the light more beautiful by contrast, just as we can shine more brightly in the midst of life’s challenges. When we allow clouds to offer us a welcome respite, they help us visit the realm of illusion to see the truth beyond.

How to Avoid Heart Attack

Here are some simple advices to avoid diseases in the heart and blood vessels and to help you recover from such diseases if you are already under attack!

…………………….HEART ATTACK

1. Kick the butt : Dr. Ashok Seth, Chairman Escort Heart Institute suggests, “Stop smoking or consumption of tobacco in any form. Smoking causes circulatory problems as it leads to cholesterol deposition and damages the inner lining of the blood vessels. It is very risky for women on oral contraceptive pills as smoking tends to increase blood clotting problems and cause blockages”.

2. Walk your way : “Exercise at least 5 days a week for 40 minutes. It helps decrease heart ailments by 20%, “adds Dr. Seth. “If you can’t take out time for jogging, cycling, playing ball, swimming or other activities, a simple technique is to indulge in a brisk 5 kilometer walk every day. Walking is the best medicine for a healthy heart. Walking increases your blood circulation,” Dr Colonel C.P. Roy VSM, Senior Consultant Max Heart Institute, adds further.

3. Sleep well : “Get enough sleep. Sleeping well reduces mental stress and stabilises one’s heart rate. Avoid stress over a long period. Manage stress by prioritising your jobs from the most important to lesser vital ones. One needs to do a proper time-management,” advices Dr. Roy.

4. Dealing with your diet : “Being careful of your diet can help you lower blood pressure and cholesterol levels. It also prevents obesity, heart disease and strokes,” mentions Dr. R.R. Kasliwal. A good diet should include vegetables and fruits together with each meal for vitamins, minerals, fibres and anti-oxidants. They should be raw or gently cooked so that the content of the nutrients remains intact. Dr. Roy further adds, “We must not only stick to fish to increase our level of Omega 3 that is good for our heart, but also try and balance our meal”.

5. Moderate your alcohol consumption : Alcohol has a devastating effect on your heart and raises the risk of high blood pressure, heart attack, and strokes. “Wine can be replaced for your regular drinks; wine increases the good cholesterol HDL level, which takes the bad cholesterol away from the blockages. But it should be consumed in limited quantity otherwise it becomes counter productive,” suggests Dr. Roy.

6. Watch your weight : Keeping a healthy weight is very important. “There is a lot of fat deposit in the Indian body; it’s the metabolic syndrome which leads to more chances of contracting diabetes and waist circumference or the waist – hip ratio. If the waist is more than the hip it leads to heart disorders, and this is very common in India. The simplest and common advice to a healthy weight is proper diet and regular physical activity, ” points out Dr. Ashok.

7. Monitor your diabetes : Keep your diabetes under control. Suffering from diabetes exposes you to heart diseases in addition to other ailments. “Blood sugar leads to hardening of the blood vessels and the deposition of cholesterol in all the arteries of the body,” says Dr Ashok. Testing for diabetes and keeping it under check is a must, blood sugar reference during fasting must ideally be 70-110 mg/dl. Eat lots of fruits and vegetables and maintain a healthy weight to keep diabetes at bay.

Dr Ashok further adds, “Blockages start as early as 3-4 years of age and major blockages can occur by 15 years of age. Regular health screenings including blood pressure, cholesterol and sugar tests during childhood once in every two 2 years and once every year in case of grown ups. In case detected with any irregularities, then a regular check is important on the advice of the doctor.”

Some Health Quaries & Answers

Q: I have male pattern baldness and want to correct it by some cosmetic procedure. I am in my twenties and not married yet. The baldness makes me look older.

….male pattern baldness

A: There have been rapid strides in the treatment of baldness. Tired of applying minoxidil daily — which is often unsuccessful — people are increasingly turning to surgical solutions. Hair can be transplanted from the sides and back of the head to the front by micro hair transplantation. This is only an outpatient procedure, with local anesthesia. Otherwise a procedure called scalp reduction is used where strips of bald skin are surgically removed.

Phantom swelling :-

Q: I have a swelling in one scrotum which appears when I stand up and disappears when I lie down. This phantom swelling is not painful.

A: It looks like you have a “reducible inguinal hernia”. A part of the contents of the abdomen is sliding into an area called the inguinal canal. As long as the to and fro movement is free, there will be no pain. However, the contents can suddenly get stuck. And this is painful and dangerous. Before this occurs, consult a general surgeon who will surgically repair the hernia.

Jock itch:-Jock itch

Q: I have uncontrollable itching and redness in my groin area. I sometimes have to leave the room in the middle of a meeting to scratch.

A: It sounds like you have “Jock itch” or Tinea cruris, a fungal infection of the skin in the groin. This is more common in men and aggravated by diabetes and obesity. It can be treated by bathing twice a day using a soap such as Neko, drying the area well and then applying anti-fungal creams like terbafine or clotrimazole (which contain no steroid). Clotrimazole powder can be applied after using the cream. The infection takes around two weeks to heal, but the application should be continued for about a week after that to prevent a recurrence. Avoid wearing many layers of clothing, change sweaty clothes immediately and dry yourself thoroughly after a bath. Steroids either applied or ingested aggravate the infection.

Irritating cough :-Irritating cough

Q: I am on Enalapril for the treatment of my hypertension. Ever since I started this, I have had an irritating cough. No matter how many different antibiotics I take, nothing works.

A: Antibiotics will not help in a cough unless it is caused by a bacterial infection. A constant cough without fever is more likely to be due to an allergen. Avoid mosquito repellents (mats, coils and liquids), room fresheners, agarbattis and camphor. Sometimes Eenalapril too can cause a cough. Try having vitamin C (500mg), half a tablet in the morning and evening. This often cures the cough.

Fair baby

Q: I am getting married soon and I would like to have a fair baby. What can I do?

A: Instead of concentrating on skin colour, it makes more sense to think “how can I have a healthy baby?” All girls should be immunised against hepatitis B (three doses) and rubella (German measles) before marriage. They need to take folic acid (5mg) every day to prevent defects in the baby’s brain and spinal cord. Walking or jogging for 40 minutes a day will build up stamina and strength in the legs, both of which are required for normal childbirth.

Painful periods :-Painful periods

Q: I have severe pain during periods. What can I do?

A: Dysmenorrhoea is the medical name for painful periods. Some women suffer more than others. The tendency to develop pain runs in families. To tackle this, have an ultrasound examination of the pelvis to make sure there is no correctable cause for the pain. If everything is normal, taking medication like Mefenemic acid (500mg) three times a day for the first two or three days brings relief.

Regular diarrhoea :-

Q: My daughter has bloody diarrhoea all the time. Her paediatrician has given her a seven-day course of metronidazole, an antibiotic, and a single dose of albendazole.

A: The diarrhoea may be because of milk allergy. This is common and often undiagnosed. Check her stool for reducing substances. If this is positive, you have hit the nail on the head. Then try stopping milk completely for 48 hours and see if there is an improvement.

Itchy skin :-Itchy skin

Q: I itch and scratch all over my body after a bath. What can I do?

A: You can :—

• Purchase a “water treatment softening device” and fit it to your bath water supply. Fitting it for the whole house is expensive.

• Add a tablespoon of coconut oil to the bath water.

• Apply a mixture of five parts of coconut oil, five parts of sesame oil and one part of olive oil to your body. Wait for 10 minutes and then bathe.

• Use a mild soap like Dove

• Apply baby oil to the whole body after your bath.

Jock Itch


Alternative Names:

Fungal infection – groin; Infection – fungal – groin; Itching in the groin; Ringworm – groin; Tinea cruris; Tinea of the groin.

Definition:
Jock itch  is an infection of the groin area caused by fungus. It is  a fungal infection affecting the moist skin on inner thighs, genitals, anal area, or buttocks, appearing in both men and women. Affected skin is covered by red or brown rash that may be ring-shaped. Rash may itch or burn; affected skin may peel off or crack.

Causes:
The body normally hosts a variety of bacteria and fungi. Some of these are useful to the body. Others can multiply rapidly and form infections. Jock itch occurs when a particular type of fungus grows and multiplies in the groin area.

English: Photo of Jock Itch around the inner thigh

English: Photo of Jock Itch around the inner thigh (Photo credit: Wikipedia)

Jock itch occurs mostly in adult men and adolescent boys. It can sometimes accompany athlete’s foot and ringworm. The fungus that causes jock itch thrives in warm, moist areas. Jock itch can be triggered by friction from clothes and prolonged wetness in the groin area (such as from sweating).

Jock itch may be contagious. It can be passed from one person to the next by direct skin-to-skin contact or contact with unwashed clothing. Jock itch usually stays around the creases in the upper thigh and does not involve the scrotum or penis. It is often less severe than other tinea infections, but may last a long time. Jock itch may spread to the anus, causing anal itching and discomfort.

Other causes of itching in the groin include:-

*Lichen simplex chronicus
*Eczema
*Pubic lice
*Chemical irritation
You may click & See also: Vaginal itching

.
How  Jock Itch Spreads?
Jock itch is easily spread with sharing towels or sportswear, or with sexual contact.

Who Normly Gets Infected?
Adult men that often have moist groin are often infected. Jock itch may also appear in women. It rarely appears before 15 years of age.

Risk factors for getting jock itch are:-

*Wet groin; (male athletes, dhobi itch is known in western washermen)
*Tight underwear
*Obesity; infection occurs in wet skin folds
*Immunodeficiency: AIDS, diabetes

Possible Completications:-
Complications are infrequent since jock itch is usually a self-limited skin condition. Rarely, the rash may spread past the groin onto the thighs and genitals. Secondary skin infections from scratching or rubbing can uncommonly deepen, causing cellulitis or abscess formation.

Another potential complication includes temporary skin discoloration called post-inflammatory hypopigmentation (lighter than the regular skin color) or hyperpigmentation (darker then the regular skin color). This altered skin color may occur after the rash has improved or after a temporary flare. Permanent scarring is uncommon.

.Symptoms:
Jock itch usually begins with mild intermittent itching in the groin. The itching can get worse and become unbearable in some cases. The rash is usually on both sides of the groin and affects the folds.

The rash may become dry, rough, and bumpy, develop pus bumps, or begin to ooze. Sometimes, the uppermost skin clears as the rash spreads further down onto the thighs. The itching and rash can spread to the genitals including the labia, vagina, scrotum, penis, and anus.

Women may also develop vaginal white discharge and yeast infections. Men may develop infections on the head of the penis, especially if they are not circumcised.

Severe cases may be very uncomfortable and develop secondary complications such as breaks in the skin, open sores, ulcers, and rarely cellulitis.
.Diagnosis:
Doctor will usually diagnose jock itch based on the appearance of the skin. Tests are usually not necessary. If tests are needed to confirm the diagnosis, either a culture or a skin lesion biopsy (for example, a scraping of the skin) may show the fungus that causes jock itch.

Rash in the groin may be caused by other types of fungi (Candida albicans), viruses (Herpes genitalis), bacteria (Staphylococcus aureus), allergies (itchy pants syndrome, cholinergic urticaria), inverted psoriasis, Darier’s disease, Hailey-Hailey disease (pemphigus), intertrigo, seborrheic dermatitis, etc.
Treatment:-
There are many treatment options and skin-care recipes for treating jock itch. Since the two primary causes of jock itch are excess moisture and fungal infections, treatment depends on the exact cause of the jock itch. Treatment of jock itch associated with skin irritation and excess moisture should address general measures to keep the groin clean and dry. Treatment of fungal jock itch should include antifungal creams used continuously for two to four weeks.

It is important to keep in mind that no therapy is uniformly effective in all people. Doctor may need to help evaluate the cause of your jock itch.

Home Remedy:-
Home remedy for mild jock itch includes:

*washing the groin skin two to three times a day with a gentle soapless cleanser like Dove non-soap cleanser or Cetaphil and water;

*keeping the groin area dry;

*avoiding excess groin skin irritation by wearing 100% cotton underwear;

*avoiding fabric softeners, bleaches, or harsh laundry detergents; and

*applying a mix of over-the-counter hydrocortisone cream and clotrimazole (Lotrimin, Mycelex) cream one to two times a day to the affected area.

Holistic jock itch treatments:-
Holistic (nonmedicated) home remedy options for jock itch include:

*Soaking the affected area daily with a washcloth dipped in dilute white vinegar (1 part vinegar to 4 parts of water) and drying the skin and

*Soaking in a bathtub daily or every other day with very dilute Clorox bleach (1 quarter cup of Clorox bleach in a bathtub full of water) and drying the skin.

Fungal jock itch is treated  Normally as follows:-

Mild fungal or yeast jock itch may be treated by:

*Washing groin twice daily with an antifungal shampoo like ketoconazole (Nizoral shampoo) or seleni
um sulfide (Selsun Blue shampoo).

Moderate fungal or yeast jock itch is often treated by a combination of:

*washing the groin twice daily with an antifungal shampoo like ketoconazole or selenium sulfide and

*Using a topical antifungal cream like miconazole (Monistat, Micatin), clotrimazole or terbinafine (Lamisil).
Severe fungal or yeast jock itch is typically treated by a combination of:

*Washing groin twice daily with an antifungal shampoo like ketoconazole or selenium sulfide,

*Using a topical antifungal cream like miconazole, clotrimazole or terbinafine, and

*Taking an antifungal pill like fluconazole (Diflucan), itraconazole (Sporanox), or terbinafine.

Bacterial jock itch is normally treated as follows:-

Mild bacterial jock itch may be treated with:

*Antibacterial skin washes like Lever 2000 soap or chlorhexidine (Hibiclens) soap twice daily.

Moderate bacterial jock itch may be treated with:

*Antibacterial skin washes like chlorhexidine soap twice daily and

*Twice-daily application of a topical antibiotic like clindamycin lotion or metronidazole (Flagyl) lotion.

Severe bacterial jock itch may be treated with:-

*Antibacterial skin washes like chlorhexidine soap twice daily,

*Twice-daily application of a topical antibiotic like clindamycin lotion or metronidazole lotion, and

*A five- to 14-day course of an oral antibiotic like cephalexin (Keflex), dicloxacillin, doxycyline, minocycline (Dynacin, Minocin), tetracycline (Sumycin), ciprofloxacin (Cipro, Cipro XR, Proquin XR), or levofloxacin (Levaquin) for more resistant situations.

Treatment of Inflammatory itching :-
Inflammatory itching from jock itch can be treated with a short course of one of the following:

*Use a short five- to seven-day course of a mild to medium potency, topical steroid cream like prescription triamcinolone 0.025% once or twice a day for inflamed or itchy areas.

*Use a short five- to seven-day course of a mild over-the-counter topical steroid cream like hydrocortisone (Cortaid) one to three times a day for itching.

*Use a topical immunomodulator such as pimecrolimus (Elidel) cream or tacrolimus (Protopic) ointment twice a day. Although these creams are approved for atopic dermatitis and eczema, their use would be considered “off label” (non-FDA labeled use) for jock itch.

Causes of Residual skin discoloration :-
Residual skin discoloration in the groin may persist for weeks to months after more severe forms of jock itch clear. This darkish discoloration is called hyperpigmentation and may be treated with one or a combination of

*Hydroquinone 4% cream,

*Kojic acid cream,

*Azelaic acid 15% cream,

*Over-the-counter fading cream with 2% hydroquinone (Porcelana), or

*Specially designed prescription creams for particularly resistant skin discoloration using higher concentrations of hydroquinone 6%, 8%, and 10% may also be formulated by prescription by compounding pharmacists.

Best Drug for Jock Itch:-
Overall, the best jock-itch drug is a topical antifungal cream like miconazole, clotrimazole, or terbinafine. If the jock itch does not improve within two to three weeks of treatment, then a physician should be consulted.

Prognosis:-
The prognosis with jock itch is very good. Overall, jock itch tends to be an easily treated and curable skin condition. Commonly, it is a mild, benign, usually noncontagious, and self-limited skin condition. More widespread, atypical cases of jock itch may be embarrassing, chronically disfiguring, and psychologically distressing for the patient.

Prevention:
Jock itch prevention efforts include good general skin hygiene and keeping your groin clean and dry. The following preventive steps will help:

*Wash groin and buttocks with soap and water after exercise and sweating.

*Wash workout clothes, underwear, and swimwear after each use.

*Minimize groin moisture by using white cotton underwear.

*Change underwear frequently and especially after sweating.

*Wash clothes and undergarments in hot soapy water.

*Use loose-fitting cotton underwear and clothing.

*Avoid undergarments with polyesters, nylon, or synthetic fibers.

*Use an antifungal powder like Lamisil or Zeasorb to keep the groin dry.

*Avoid fragranced or irritating creams or lotions on the groin.

*Avoid going barefoot, especially at gyms, schools, and public pools.

*Treat athlete’s foot if you have it.

*Cover your feet with socks before you put on your underwear and pants.

What Causes Arteries Clog Up

British scientists have identified an enzyme that plays a crucial role in clogging up of arteries . Here’s what causes arteries to clog up (Getty Images)
Here’s what causes arteries to clog up

They have discovered that an enzyme called matrix metalloproteinase-8 that raises blood pressure and causes abnormal build-up of cells in the arteries – both of which increase the risk of heart disease.

“Our research tells us that this enzyme plays a crucial role in the build-up of fatty deposits in the arteries which causes heart disease,” said lead researcher Shu Ye, Professor of Molecular Medicine and Genetics at Queen Mary, University of London.

“Many patients with high blood pressure or heart failure are currently treated with ACE inhibitor drugs. However, some patients do not respond sufficiently to ACE inhibitors alone.

“We hope that what we’ve found here could be the basis for new drugs that can enhance the effects of ACE inhibitors, which would reduce deaths from heart disease,” Ye added.

During the study, researchers genetically engineered mice to lack the MMP8 enzyme.

The mice were fed on a Western-style diet high in fat and cholesterol and compared to normal mice fed on the same diet. The mice, which lacked the enzyme, had clearer arteries and lower blood pressure.

The researchers also studied 2,000 patients who were being tested for clogs in arteries leading to their hearts with a test called a coronary angiogram.

They found that around 25 per cent of these patients had a slightly different version of the gene for MMP8 and their arteries were more clogged than other patients.

Meditate Your Pain Away

Zen meditation – a centuries-old practice that helps people gain mental, physical and emotional balance – can keep pain at bay
CLICK & SEE THE PICTURES
Universite de Montreal researchers.

According to a Psychosomatic Medicine study, Zen meditators have lower pain sensitivity both in and out of a meditative state compared to non-meditators. Along with Pierre Rainville, a professor and researcher at the Université de Montréal, Joshua A. Grant, a doctoral student in the Department of Physiology co-authored the paper.

The main aim of the study was to examine whether trained meditators perceived pain differently than non-meditators. “While previous studies have shown that teaching chronic pain patients to meditate is beneficial, very few studies have looked at pain processing in healthy, highly trained meditators. This study was a first step in determining how or why meditation might influence pain perception,” says Grant.

To reach the conclusion, the scientists recruited 13 Zen meditators with a minimum of 1,000 hours of practice to undergo a pain test and contrasted their reaction with 13 non-meditators. Subjects included 10 women and 16 men between the ages of 22 to 56.

The administered pain test was simple: A thermal heat source, a computer controlled heating plate, was pressed against the calves of subjects intermittently at varying temperatures. Heat levels began at 43 degrees Celsius and went to a maximum of 53 degrees Celsius depending on each participant’s sensitivity. While quite a few of the meditators tolerated the maximum temperature, all control subjects were well below 53 degrees Celsius.

Grant and Rainville noticed a marked difference in how their two test groups reacted to pain testing – Zen meditators had much lower pain sensitivity (even without meditating) compared to non-meditators. During the meditation-like conditions it appeared meditators further reduced their pain partly through slower breathing: 12 breaths per minute versus an average of 15 breaths for non-meditators.

“Slower breathing certainly coincided with reduced pain and may influence pain by keeping the body in a relaxed state. While previous studies have found that the emotional aspects of pain are influenced by meditation, we found that the sensation itself, as well as the emotional response, is different in meditators,” Grant said.

The ultimate result was that Zen meditators experienced an 18 per cent reduction in pain intensity.

Coconut Oil Could Ward Off Type 2 Diabetes.

Diet Rich  Coconut Oil Could Stop Type 2 DiabetesA diet rich in coconut oil could ward off Type 2 diabetes.

…………coconut
The oil, used in foods such as margarine, helps prevent insulin resistance.

This is where muscle and fat cells stop reacting to insulin, the hormone that helps to mop up excess sugar in the blood.
Australian scientists used mice to compare the effects of coconut oil-rich foods with a lard-based diet, consumed by many in the developed world.
The results showed coconut-fed mice were much less likely to develop resistance to insulin. Previously, coconut oil has had a mixed reception because it is high in saturated fat, which is linked to high cholesterol.

But coconut fat is now known to be made up of so-called ‘medium chain’ fatty acids, regarded as healthier than the long-chain fatty acids found in animal products such as butter or lard.

When ‘Baby Fat’ is Good for Health

Want to shed your baby fat? Wait, don’t do it just yet, for a new study has revealed that such a fat is good – as long as it is calorie-burning -”Brown Fat”.

When 'baby fat' is good for health

Brown fat burns off calories and generates heat in babies and small mammals.

Most of the body fat is white fat, which also provides insulation but stores calories. It becomes “bad” fat when an individual have too much. The “good” fat-brown fat-was considered essentially nonexistent in human adults.

The new study has found that adults have much more of this type of fat than previously believed.

“We now know that it is present and functional in adults,” said the study’s lead author, Dr Aaron Cypess, MMSc, of the Joslin Diabetes Centre in Boston.

“Three ounces of brown fat can burn several hundred calories a day,” he added.

In the new study involving 1,970 study participants, researchers measured the patches of brown adipose tissue-brown fat-in people with the help of high-tech imaging method that combines positron emission tomography and computed tomography, called PET/CT.

By evaluating biopsy tissue of what appeared to be brown fat, the authors confirmed that they were, indeed, looking at stores of brown fat.

The researchers found that brown fat was located in an area extending from the front of the neck to the chest.

Of the subjects who had detectable brown fat, about 6 percent had 3 ounces or more of the fat.

“We believe that this percentage greatly underestimates the number of adults in the population who have a large amount of brown fat,” said Cypess.

They also discovered that brown fat is most abundant in young women and least frequent in older, overweight men. In fact, women were more than twice as likely as men to have substantial amounts of brown fat.

“One theory for this is that women may have less muscle mass overall, so they need more brown fat to generate heat and keep warm,” Cypess said.
