US study: Vegetarians may be happier

While fish may serve as the major dietary supply of the long-chain omega-3s eicosapentaenoic acid and docosahexaenoic acid, which has been shown to be essential in supporting brain health, low intake of eicosapentaenoic acid and docosahexaenoic acid in vegetarians will not adversely affect mood, based on a new research.

A study team from Arizona State University conducted a cross-sectional study to check the mood of vegetarians who never eat fish with the mood of healthy omnivorous adults.

An overall total of 138 healthy Seventh Day Adventist adults residing in Arizona and California (64 vegetarians and 79 non-vegetarians) were enrolled in the study and completed a health history questionnaire, food frequency questionnaire and two psychometric tests, the Depression Anxiety Stress Scale and also the Profile of Mood States.

Vegetarians had significantly lower mean intakes of eicosapentaenoic acid, docosahexaenoic acid and also the omega-6 arachidonic acid; they had higher intakes of the omega-3 alpha-linolenic acid and the omega-6 linoleic acid.

"Seed oils are the richest sources of α-linolenic acid, notably those of rapeseed (canola), soybeans, walnuts, flaxseed (Linseed oil), clary sage seeds, perilla, chia, and hemp."

However, the vegetarians also reported considerably less negative emotion than omnivores in psychometric tests. Mean total psychometric scores were positively associated with the mean intakes of eicosapentaenoic acid, docosahexaenoic acid and arachidonic acid , and inversely related to alpha-linolenic acid and linolenic acid intake.

The study team noted there is also the possibility that vegetarians may make smarter dietary choices and may generally be healthier and happier.

Italian Spaghetti with Zucchini

Ingredients:

* 17 oz. Spaghetti

* 24 oz. Of thin sliced zucchini

* A half cup of walnuts oil

* A few basil leaves

* 2 tablespoons of yeast flakes

* Salt and pepper

In a skillet or frying pan heat the oil and when hot, add garlic and zucchini. Raise heat and stir often to complete their cooking. They should be golden and crispy outside and tender inside. Cook the pasta, drain and sauté in pan with zucchini, basil and yeast. Serve immediately.

Zucchini contain fewer calories and have no fat. But they are an excellent source of potassium, e vitamin, vitamin c, folate, lutein and zeaxanthin.

Many of these nutrients are extremely sensitive to heat and to enjoy their benefits you need to look for a quick solution to cook or even eat raw in salads.

From the therapeutic perspective, zucchini have laxative, refreshing, anti-inflammatory, diuretic and detoxifying action

Nine reasons to drink green tea daily

Have you been wondering “what’s all the fuss about green tea?” Now you can stop wondering and start drinking ... green tea, that is. This flavorful beverage offers many health benefits to anyone who drinks it regularly. Green tea contains a potent plant nutrient known as epigallocatechin gallate, or EGCG, for short. But don’t fret, you don’t have to keep track of its chemical name to reap the health benefits.

Here are nine reasons to start drinking green tea or continue drinking it if you’re already hooked.

1. Green tea is a superb fat fighter. Its active ingredient, EGCG, increases the rate at which fat is burned in your body.

2. It targets belly fat. Research at Tufts University indicates that EGCG in green tea, like other catechins, activate fat-burning genes in the abdomen to speed weight loss by 77 percent.

3. Green tea keeps energy stable by balancing blood sugar levels. EGCG improves insulin use in the body to prevent blood sugar spikes and crashes that can result in fatigue, irritability, and cravings for unhealthy foods.

4. Research shows it may be helpful against lung cancer. In an April 2010 study published in Cancer Prevention Research, EGCG was found to suppress lung cancer cell growth.

5. Green tea may halt colorectal cancer. In numerous other studies, EGCG appears to inhibit colorectal cancers.

6. In research, it appears to cause prostate cancer cells to commit suicide. A March 2010 study in Cancer Science indicated that EGCG aids the body by causing prostate cancer cells to commit suicide.

7. Green tea may prevent skin damage and wrinkling. EGCG appears to be 200 times more powerful than vitamin E at destroying skin-damaging free radicals. Free radicals react with healthy cells in the body, causing damage, so lessening their numbers may help reduce wrinkling and other signs of aging.

8. It contains a potent antioxidant that kills free radicals. Because it is a potent antioxidant green tea can positively impact a lot more than skin cells. Free radicals are increasingly linked to many serious chronic illnesses like arthritis, diabetes, and cancer.

9. Green tea tastes good. If you’re not wild about the flavor, try a few different kinds. Try it iced or hot. Add some of the natural herb stevia to sweeten it if you want a sweeter drink. I wasn’t crazy about green tea the first few times I tried it, but now I love it with a fresh squeeze of lemon and a few drops of stevia over ice -- et voila! Green tea lemonade. Mmmmm.

Reap the rewards

Add one or two teaspoons of green tea leaves to a cup of boiling water, preferably in a tea strainer. Let steep for five minutes. Pour over ice if you prefer a cold beverage. Most experts recommend three cups daily. And, don’t worry, green tea contains a lot less caffeine than coffee or black tea.

Womb to let

An Israeli social anthropologist describes the process of surrogacy, which enables couples to be parents by relying on a hired stranger.Since Israel’s pathfinding surrogacy law – the first in which government supervises women being paid to gestate the embryos and deliver the babies of couples unable to have their own – was passed in 1996, about 350 children have been born. A few heartwarming stories about childless couples becoming parents and some sensational ones about surrogates who regretted their role have hit the media, but there has been no objective assessment of how the law has been implemented and how it affected those involved.

At least until now. A comprehensive, 361-page, English-language masterpiece on surrogacy by an Israeli social anthropologist, Dr. Elly Teman, has just been published by the University of California Press (www.ucpress.edu/books/pages/11401.php). Academic and well-researched, moving and sensitive, Birthing a Mother: The Surrogate Body and the Pregnant Self concludes that the law was well designed and is being fairly implemented.

Around the world, some feminists have denounced surrogacy for allegedly taking advantage of the women who bear the babies, while others have claimed it is “abnormal” for a surrogate to forgo a baby she carried, even if it was not her biological child.

Although Teman writes in the world’s first “ethnographic study” on the subject that “surrogacy does have the potential to exploit women..., the voices of surrogates counter automatic presumptions of exploitation by showing that a majority achieve a degree of appreciation through surrogacy that they do not get otherwise from partners or from society at large.”

At the same time, despite fears of opponents, Teman found that surrogacy arrangements in Israel did nothing to erode the nuclear family; instead, it reflected Israel’s conservative approach to reproduction and reflected the pro-birth ideology of a mostly Jewish society facing dangerous enemies.

Teman, who was born in Brooklyn, New York and raised in Portland, Oregon, was brought to Israel as a teenager. After completing her military service and traveling in the Far East, she began her studies at the Hebrew University, where she completed a doctorate in social anthropology.

SHE FIRST became interested in the topic about two years after the law was passed, and soon after the delivery at Haifa’s Rambam Medical Center of the first surrogate children – girl and boy twins – in February 1998. As a graduate student in anthropology, she worked as an interpreter for visiting US law Prof. Kelly Weisberg, who came to Hebrew University to do research about her own book, The Birth of Surrogacy in Israel. One day, Teman accompanied Weisberg to an interview with “Yael,” who as a woman who could not carry her own embryos to delivery lobbied for the law; she and her husband later contracted a single woman to carry their baby. Teman writes in her book ($55 hardcover/$22 softcover) that although she had never given such a situation much thought, she was “profoundly touched” by Yael’s personal story and became good friends with her, ultimately deciding to devote eight years to interviewing many of the surrogates and “intended mothers.”

Her book is the result of 43 in-depth, formal conversations with 26 surrogates and 45 interviews with 35 intended mothers; most of these encounters took place in the interviewees’ homes, and often included looking at home videos and photo albums. In some cases, she spoke to both the surrogate and the woman who was to take home the baby. She was also in touch with some of the intended mothers and surrogates during the pregnancy and after the births, and in contact in person or by e-mail with “two-thirds” of those involved in Israeli surrogacy arrangements between 1998 and the end of 2005. The academic nature of the work is demonstrated by her 60 pages of notes and bibliography.

Teman and her husband Avi currently live in Philadelphia with their two children, Uriel and Rachela, while she is working as a research fellow at the Penn Center for Integration of Genetic Healthcare Technologies at the University of Pennsylvania. They intend to return home to Israel after concluding her postdoctoral work.

CONTRARY TO the image of surrogates as being desperate women who undergo the implantation of embryos of a couple just for the roughly $25,000 payment, Teman found that about 30 percent were Israeli middle-to lower-middle-class who worked at a steady job, owned cars and lived in pleasant homes. They usually lived with boyfriends and decided to be a surrogate to provide “extras” for their family. About half were lower-class single parents, divorced, widowed or never married, who thought the money would give them a “financial push forward.” The rest, said the author, lived in delapidated apartments in poor areas and thought surrogacy would be a better way to pay their bills than, say, selling a kidney. Teman said the economic and class differences between Israeli surrogates and intended mothers were quite a bit smaller than their counterparts in the US, where surrogacy is arranged privately and for much higher sums. The would-be surrogate must be currently unmarried, have at least one child of her own, must not have miscarried or delivered prematurely, and be free of psychological or physical problems.

UNLIKE COMMERCIAL arrangements in other countries where surrogacy is not illegal, the intended mothers are not rich career women who want children but don’t want to be bothered (or become “misshapen”) by pregnancy. All of them have undergone many failed in-vitro fertilization (IVF) cycles, miscarried many times and were born without or lost their uterus due to disease. Some had no healthy ova of their own and had to obtain donor eggs to be fertilized by their husbands’ sperm. Under the law, all intended parents have to be heterosexual and married, with the written agreement approved by a Health Ministry committee and recognized by a court. No Muslim or Christian Arabs have been surrogates or intended parents, as Islamic law prohibits surrogacy, and strong stigmas surround the practice in the Christian Arab community, Teman writes. However, a homosexual couple recently petitioned the High Court to give the Knesset the authority to allow them to apply as well.

The contract worked out by the two parties includes many details, possibly including whether the surrogate can work or smoke, and what she may not eat or do during the pregnancy, what happens if she miscarries or the baby is born defective, how she is paid, and other important details. While the pre-surrogacy supervision is stringent, the state avoids intervention during most of the pregnancy. But at delivery (either vaginal or in many cases by cesarean section), the baby is whisked off and given to the intended mother (who sometimes is hospitalized in the maternity ward) and her husband, while the surrogate is rolled into the gynecology department until her discharge. The baby immediately and officially becomes the natural child of the couple (who like the surrogate receive a maternity allowance) and is entered into their identity cards.

Teman stresses that while the Orthodox religious establishment in Israel might have been expected to fight legal surrogacy, opposition was overcome by Judaism’s highly positive views of having children and using almost any means to achieve this. Added to this imperative is Israel’s national culture of increasing the population.

Surrogacy and taking home one’s biological baby are described by many participants interviewed as powerful experiences that change lives. “And that’s why I say, I didn’t just give birth to a baby; I gave birth to a mother,” declares Tamar, a surrogate, even before the volume’s text begins. “I always say my mother gave birth to me the first time; she gave me life. But my surrogate gave me life the second time,” says Shlomit, an intended mother.

The IVF procedure and embryo transfer are quite complicated, requiring a series of rather painful hormone shots in the buttocks of the biological mother to ripen her ova, which are fertilized in a glass dish by her husband’s sperm. The surrogate too undergoes shots to coordinate her reproductive system with that of the biological mother so her uterus will be maximally prepared to receive the embryo(s).

IN A VERY interesting chapter, the author explains that the surrogates she interviewed have a different vocabulary and use special metaphors for parts of their bodies to separate themselves from the commissioning couples’ fetuses. One called herself an “oven that bakes the bread for hungry people. I just help them... Like if my friend needed a loan, I would save from my own food, and I would give her a loan. Would they then say I am being used?” Another surrogate said she was “someone with a womb, a good womb ... I just held [the fetuses] in my belly, like an incubator... I was their incubator for nine months... And the second that they were born, I finished the job and that was it.

Many of the surrogates described their commissioned pregnancy as very different physically from when they bore their own child – little or no nausea or food urges, for example. It was as if their womb belonged to someone else, and their emotions toward the fetus were nonexistent. In no case did any surrogate chronicled by Teman express a desire to keep the baby they had delivered.

The relationships between surrogates and intended parents were often very close, especially between the women. Some said they would do anything for the biological mother and felt the need to update her daily on what she felt so that the mother – who could never become pregnant – would be able to “experience” it. Some of the commissioning mothers developed symptoms of pregnancy – even high levels of pregnancy hormones – as a way of entering their future role. They invariably fondle the belly of their surrogate to feel fetal movements and hear the heartbeats and drive the surrogates to tests and spoil them. Sometimes even the father is allowed by the surrogate to be present for vaginal ultrasound scans, not to mention the birth. But in some cases, the relationship becomes very sticky, and Teman describes cases in which the couples develop severe psychological dependence and make too many demands, forgetting the boundaries of the surrogate’s self. Yet some surrogates also worry about the sudden disconnection from the couple, fearing they will lose them as friends. Surrogate e-mail forums and Web sites often carry such stories and give advice to avoid the minefields.

Teman notes that the law has its drawbacks, including the directive that surrogates must be single women, that gay couples and single persons cannot hire surrogates, and that intended mothers must first have made repeated IVF attempts to prove their candidacy. “However, the legislation also protects surrogates, couples and the resultant child. The government ensures that parties are diligently screened and that all contracts are valid.” It is the quality of the surrogate’s relationship with the couple that largely determines her satisfaction with the experience. The Israeli surrogacy law, minus some of the restrictions required by Jewish law, could serve as a model for other countries, the author concludes.

L’acné des adultes

Alors que les boutons et autres points noirs sont associés aux problèmes d’adolescent, l’acné des adultes est pourtant plus commune que ce que l’on pense. Tout comme les adolescents, l’acné est souvent mal vécue par l’adulte et ces imperfections gâchent souvent la vie. Même si on ne l’étudie que depuis 10 ans environ, les causes les plus courantes de l’acné adulte sont connues, et on sait même comment le traiter. Les causes : De nombreuses causes sont évoquées pour l’acné des adultes. Et comme presque tous les cas d'acné (chez les ados ou les adultes), l'acné résulte d’une surproduction de sébum qui occasionne la prolifération de points noirs et une inflammation du follicule pilo-sébacé qui engendre ces nombreux boutons disgracieux.

Chez l'adulte d’ailleurs, l'acné se manifeste autrement que chez l'adolescent : les points noirs sont des boutons bien rouges, présents surtout sur la mâchoire inférieure, chez la femme, et dans le dos, chez l'homme. Les femmes de 25 à 40 ans sont d’ailleurs plus touchées que les hommes par l’acné des adultes. Quelques facteurs sont vus comme déclencheurs pour l’acné des adultes.

Tout d’abord les soins cosmétiques de mauvaise qualité, ou, ceux mal adaptés à son type de peau peuvent entraîner des risques d'allergies et de réactions cutanées. Mais, la liste ne s’arrête pas là : on peut parler aussi du stress, de la pollution, de la contraception, des menstruations, des grossesses ou de la sensibilité hormonale...

A savoir : ce n’est pas forcément parce que vous avez été touché par l’acné juvénile que vous serez sujets à l’acné des adultes.

L’hygiène de vie
Jusqu’à aujourd’hui, aucune étude n'a démontré que le chocolat, les frites ou la pizza aggravaient l'acné. Idem pour l'alcool. Mais même si rien n’est prouvé, la nourriture trop grasse n’est de toute façon pas trop bonne pour la santé. Alors, si vous êtes touchés par l’acné des adultes, il vaut mieux manger équilibré et sainement, et préférer les produits naturels comme les légumes ou fruits frais.

Pour les cigarettes par contre, des études ont montrée que les cas d'acné adulte sont plus importants chez les fumeurs, et surtout, que ces derniers répondent moins bien aux traitements dermatologiques que les non-fumeurs.
Bien nettoyer sa peau

Avant même d’utiliser un traitement, il est important de bien nettoyer sa peau, car souvent en effectuant des gestes efficaces, votre acné peut disparaître ou du moins diminuer. Pour enlever le surplus de sébum et assainir la peau, il vaut mieux utiliser des solutions nettoyantes sans savon (et il vaut mieux éviter les laits démaquillants sans rinçage car ils laissent un film gras sur l'épiderme) à faire mousser, sans frotter, sur tout le visage (et non pas seulement sur les zones boutonneuses) à l'aide d'eau tiède. Une fois que sa peau est bien sèche, on applique un tonique sans alcool ou une eau thermale apaisante et on termine par un hydratant non comédogène adapté à son problème cutané lorsque l’on suit un traitement (le soir, ce produit peut être remplacé par un traitement ciblé plus puissant, et donc plus asséchant).

A savoir : si vous vous maquillez, l’important est d’avoir la main légère en évitant la couche de fond de teint épaisse qui empêche la peau de respirer. Préférez utiliser une crème teintée matifiante avec un peu de poudre que le fond de teint.

Le traitement
L'acné se guérit. Avec l'âge, les glandes sébacées s'atrophient d’elles-mêmes, si bien que, au-delà de la cinquantaine, les cas d'acné sont rares. Des dizaines de traitements en vente libre sont vendus en pharmacie. Demandez conseil à votre médecin ou pharmacien. Les traitements les plus utilisés sont ceux à base de trétinoïne, d'acide salicylique, de peroxyde de benzoyle ou de lipohydroxyacide (LHA).

Si ces solutions de base s'avèrent inefficaces, allez consulter un dermatologue qui pourra vous proposer divers traitements médicaux (plus ou moins long). Il peut vous prescrire un des nombreux traitements d'anti-acnéiques locaux (pour lutter contre le développement bactérien et agir sur la sécrétion de sébum) et des traitements généraux par voie orale sont également envisageables.

Le saviez-vous ? Environ 25% des adultes seraient touchés par l’acné des adultes.

Yoga helps cancer survivors breathe easier

Gale McCombie was sitting in a hospital waiting room when she spotted a brochure offering free yoga classes for cancer patients. But zapped of strength and confidence after undergoing grueling treatments for breast cancer, McCombie found the thought of entering any exercise class intimidating.

"Chemo left me in a pretty bad state as far as my physical ability. But everybody talked about the importance of physical activity, and yoga seemed to be a good start," the 50-year-old Canadian said in an interview"I took my mom with me for comfort. I didn't know what to expect. But the others had cancer, too. And the facilitator made sure everyone was comfortable with props, modifications, whatever it took. After the first class I was fine."

McCombie joined Yoga Thrive, a community-based program created specifically for cancer survivors that is spreading throughout Canada and parts of the United States.
The brainchild of Dr. Nicole Culos-Reed, a cancer and exercise researcher at the University of Calgary, and Susi Hately, a yoga instructor, Yoga Thrive provides gentle, therapeutic yoga to people at all stages of cancer treatment.

"Our instructors know both cancer and yoga," Culos-Reed explained. "They not only learn the seven- week yoga program, they also learn about cancer treatments and side-effects."Culos-Reed, herself a yogi for seven years, believes the 5,000-year-old practice, which strives to align breath with movement, is particularly suited to cancer patients.

"They learn to reconnect with their breath and their body again," she said. "There's that unique body-mind connection. When someone's going through cancer, everything seems out of control."That includes one's finances. Cancer can cost a patient upwards of $100,000, so Yoga Thrive classes are offered free or for a nominal fee, and there is a DVD that sells at cost.

Culos-Reed says studies indicate that exercise improves the strength, flexibility and general quality of life of cancer survivors."There is research that colorectal cancer patients who exercise regularly have a greater survival rate," she said. "We don't know the mechanism, but there's a definite link."

That connection inspired entrepreneur Halle Tecco to create Yoga Bear, a San Francisco-based non-profit that offers cancer survivors free yoga classes by partnering with yoga studios and hospitals.Tecco founded Yoga Bear in 2006, after reading a paper on yoga and cancer. Today more than 180 yoga studios across the United States have donated passes to her organization."We also send trained instructors to hospitals to teach classes to those undergoing treatment," she said in an interview.

Because 70 percent of participants are new to yoga, Yoga Bear provides a handbook with detailed tips on what to wear, bring, and expect."We recognize that they may experience nervousness prior to their first class," Tecco said.McCombie is now back at her job as an executive assistant for an oil company.

"When I started yoga I couldn't even get off the floor by myself. I needed help," she said, referring to her lack of strength . "Now I can do (climb) stairs." And just as important, she says, yoga helped her to relax. "When you're going through cancer, you've got all these treatments and doctors' appointments. You've got to calm yourself. I try constantly to bring myself back to the moment."

Plague outbreak in China

Medical staff raced to disinfect a sealed-off town in northwestern China on Tuesday after a third person died within four days in a pneumonic plague outbreak in the farming community of 10,000, local authorities said.Police set up checkpoints around Ziketan in Qinghai province after the outbreak was first detected last Thursday. The lung infection is highly contagious can kill a human in 24 hours if left untreat.

Medical staffs are disinfecting the area and killing rats, insects and fleas that can be carriers for the bacteria, a notice on the provincial health department Web site said. Authorities are keeping close track of people who came into contact with those infected.
Authorities urged anyone who had visited the town since mid-July and has developed a cough or fever to seek hospital treatment. Pneumonic plague is spread through the air and can be passed from person to person through coughing.

The latest victim was a 64-year-old man named Danzhi, the official Xinhua News Agency said.He was a neighbour of a 32-year-old herdsman in Ziketan and a 37-year-old man who died earlier. A further nine people — mainly relatives of the herdsman — are infected and in a hospital, according to the local health bureau.Of those, one is in an extremely serious condition and one other has developed symptoms of coughing and chest pain, but the rest are in stable condition and there have been no reports of new infections, Xinhua and the health department said.

Police checkpoints were set up in a 17-mile (28-kilometer) radius around Ziketan and people were not allowed to leave, a resident said. Many shops remained closed Tuesday, residents said, although more vehicles were out on the street.Some people tried to leave the quarantined area on Monday evening after the third death was reported.

"A lot of people ran off last night when they heard that another person died of this plague. They are mostly from other provinces," said a foodseller surnamed Han who runs a stall at the Crystal Alley Market. "They headed back home with food, mineral water and their donkeys."It was unclear if the people who headed out of the town made it past the police checkpoints. Officials at the local and provincial level were unavailable to comment.According to the World Health Organization; pneumonic plague is one of the deadliest infectious diseases, capable of killing humans within 24 hours of infection.

A 2006 WHO report from an international meeting on plague cited a Chinese government disease expert as saying that most cases of the plague in China's northwest occur when hunters are contaminated while skinning infected animals. Pneumonic plague is caused by the same bacteria that causes bubonic plague — the Black Death that killed an estimated 25 million people in Europe in the Middle Ages. However, bubonic plague is usually transmitted by flea bites and can be easily treated with antibiotics.

Le Thé Vert et le Sida

Un composant du thé vert prometteur contre la propagation du sida... Un composant du thé vert pourrait se révéler efficace pour éviter une contamination par le virus du sida au cours de relations sexuelles, affirme une étude allemande publiée mardi dans l'édition en ligne des Proceedings of the National Academy of Sciences (PNAS). Cette étude de l'université d'Heibelberg et de l'Institut de virologie expérimentale de Hambourg a montré que le gallate d'Epigallocatechin (EGCG), un polyphénol ou tanin végétal du thé vert, a la capacité d'inhiber une protéïne du sperme qui a tendance à servir de vecteur et de propagateur du virus du sida. "Une fraction de peptide contenue dans le sperme humain renforce de façon constante une infection par le VIH. Des fibrilles, baptisées propagateurs d'infection du virus par le sperme (SEVI, Semen-derived enhancer of virus infection), (...) captent des éléments viraux et les accrochent à leur cellule cible, propageant la fusion du virus dans ces cellules", expliquent les chercheurs du "Heinrich-Pette-Institute de Hambourg".

"Pour ces raisons, nous avons supposé que l'inclusion d'un inhibiteur de SEVI en tant que microbicide pourrait améliorer la prévention de la transmission du sida par les relations sexuelles", expliquent les chercheurs. Ils ont démontré que l'application locale, chez les femmes, d'une solution à basse dose de polyphénol de thé vert (EGCG) peut "annihiler de façon efficace les propriétés de développement de l'infection".

Alors que la vaste majorité des 33 millions de séropositifs dans le monde ont été infectées par le VIH au cours de relations hétérosexuelles et que 96% des nouvelles contaminations interviennent dans les pays pauvres, les chercheurs estiment que la découverte des propriétés inhibitrices du composant du thé vert est "prometteuse".

"Cela peut apporter une méthode simple et peu coûteuse de prévention, particulièrement dans les milieux défavorisés", ajoutent les chercheurs."L'EGCG apparaît comme un supplément prometteur aux microbicides anti-rétroviraux afin de réduire la transmission du sida par les relations sexuelles", conclut l'étude."L'EGCG du thé vert a déjà été reconnu pour ses propriétés antitumorales, antioxidantes, antibactériennes et antivirales".
