#Warm-up Bringing Allergy Woes to Northeast This article was provided by Accuweather. com. Seasonal allergies will be in full swing this week in the Northeast as seasonable temperatures take hold.

However with these warmer temperatures comes the return of seasonal allergies. With milder conditions starting in the beginning of April the growing season has started really up.

However it is not the bright showy flowers that cause most problems for allergy suffers.

This sudden boom in tree blossoms could have allergy sufferers seeing symptoms more abruptly than usual.

As per this time of year the tree pollen is the main allergy threat especially from the less conspicuous oak maple pine and elm varieties.

and even southeastern New england so has the allergy threat. What seems to have awakened the trees was the sudden warmth early last week followed by drenching rain in many areas.

The combination of the two will continue to spur on blossoming and pollen release. Even though rain temporarily removes some of the pollen from the air it promotes a new round of blossoming this time of the year.

#What and When to Eat to Build Muscle (Op-Ed) Katherine Tallmadge M. A r. D. is registered a dietitian author of Diet Simple:

The American College of Sports Medicine recommends doing strength training for all of your major muscle groups at least twice a week.

Studies of 80-year-olds show muscular strength can mean the difference between independence and a nursing home:

Bone health muscle function muscle strength muscle mass and immune function all are impaired with a low intake of protein.

New research has found that eating the right amount of protein nd at the right times is essential not only for your general health

and can damage your health in many ways.)If you're losing weight or are worried about muscle

Apparently as people age oxidative stress and inflammation cause age-related breakdowns of muscle and bone.

Tea's healthy compounds called polyphenols reduce oxidative stress and inflammation preventing this breakdown and even improving muscular strength and bone mass.

A recent study funded by the National institutes of health's National Center for Complementary and Alternative medicine looked into tea's effects on muscle.

In the study postmenopausal women with osteopenia (the beginning of osteoporosis or brittle bones) were given tea

or performed Tai Chi exercises. After six months the tea alone caused an improvement in muscle strength and bone-building biomarkers.

You can learn more about the health benefits of tea here. Tai Chi alone certainly not the rigorous or impactful exercise that researchers understand is necessary for muscle

Apparently Tai Chi reduces inflammation and oxidative stress too. With the amazing results of that study in mind it makes sense that any foods high in antioxidants

and anti-inflammatory compounds such as fruits and vegetables may help improve bone and muscle strength. And if Tai Chi helps improve bone

but also some fish and dairy thought to be nutritionally dense and thus good for one's health.

Superfoods are healthful for the most part aside from possible contamination added sugars or over-consumption of them.

Another problem with the term is that some so-called superfoods fall in and out of favor with dieticians such as coffee or eggs.

This could be thought an antioxidant to ward off cancer; a healthy fat thought to prevent heart disease;

fiber thought to prevent diabetes and digestive problems; or phytochemicals the chemicals in plants responsible for deep colors and smells which can have numerous healthful benefits.

Blueberries often top many lists of superfoods. This is because blueberries are rich in vitamins phytochemicals and soluble fiber.

Salmon sardines mackerel and certain other fatty fish are rich in omega-3 fatty acids thought to lower the risk of heart disease and stroke.

Most doctors say the benefits of eating fish far outweigh the risk of harming your health from the mercury these fish contain.

For example a search for superfood on Pubmed the repository of most peer-reviewed biomedical journal articles yields fewer than a dozen results.

and promotes insulin-resistance obesity and diabetes. A second criticism is that because the term superfood is not scientific it can mean very little and prompt some consumers to eat one kind of food over another.

#What Is Anthrax? Anthrax is caused an infectious disease by the bacterium Bacillus anthracis. The bacteria live in soil

and usually infect wild and domestic animals such as goats cattle and sheep. Anthrax outbreaks are fairly common worldwide and mostly affect agricultural workers.

Humans become sick with the disease by handling animal products such as wool hide or bone from animals infected with the anthrax bacterium.

The most common form of the disease cutaneous anthrax is contracted when bacteria spores enter the body through a cut or scrape on the skin.

Of the three forms of the disease cutaneous pulmonary and gastrointestinal cutaneous anthrax is the easiest to treat with antibiotics.

Anthrax can also be inhaled into the human respiratory tract this pulmonary method of infection is most common among those who process wool

and animal hides according to the U s. National Library of Medicine. Those with pulmonary anthrax are at risk of respiratory collapse

and suffer the highest mortality rate of any anthrax victims with 92 percent of cases resulting in death.

The third form of the disease gastrointestinal anthrax can occur when a person consumes the meat of an anthrax-infected animal.

This is the rarest form of anthrax in the United states but it can be deadly: Between 20 and 60 percent of all gastrointestinal-anthrax cases result in death according to the Centers for Disease Control and Prevention (CDC.

Anthrax and bioterrorism Anthrax can be created easily in a lab and is incredibly durable: Spores of anthrax bacteria can lie dormant for years before entering a living host where they reactivate

and multiply. These characteristics make anthrax an extremely dangerous bioterrorism weapon. Anthrax has been used in bioterrorism

and warfare since World war i when Scandinavia deployed anthrax against the Imperial Russian Army. It was used also by The british army during WORLD WAR II to weaken German livestock.

More recently anthrax has been used in bioterrorism attacks in both Japan and the United states. In 1993 a religious cult in Japan deployed anthrax against civilians in Tokyo

but the attack yielded no injuries or fatalities. In 2001 letters containing anthrax spores were mailed to several news-media offices

and two U s. senators resulting in the deaths of five people and the infection of 17 others.

#What Is bonded Leather? If you've purchased a relatively cheap leather sofa leather-bound books

or an inexpensive belt you might own a bonded-leather item. But what is bonded leather?

Bonded leather consists of scraps from real leather hides that are mixed with polyurethane a type of plastic.

The material should include from 60 to 100 percent real natural leather such as cowhide according to manufacturing standards.

The actual proportion depends on the quality level maintained by the manufacturer. To make bonded leather manufacturers use the scraps and fibers left over during the production of real leather items.

Blended with plastics these scraps are attached to a hard-fiber backing. Manufacturers also frequently add coats

and polishes to make the material look more leatherlike. Real leather items by contrast use the whole skin of an animal not scraps.

The advantages of bonded leather include its lower cost and environmental friendliness since it makes use of reclaimed

but some people are gluten-intolerant meaning their bodies produce an abnormal immune response when it breaks down gluten from wheat and related grains during digestion.

The most well-known form of gluten intolerance is celiac disease which affects one in every 141 people in the United states according to the National institutes of health.

When someone with celiac disease consumes gluten it triggers an immune response that damages their intestines preventing them from absorbing vital nutrients.

 Wheat allergy is a rare type of gluten intolerance it's a classic food allergy marked by skin respiratory or gastrointestinal reactions to wheat allergens.

Recently scientists have become aware of another potential form of intolerance called nonceliac gluten sensitivity.

After consuming gluten patients with gluten sensitivity may experience many celiac disease symptoms such as diarrhea fatigue

In cases of gluten intolerance doctors typically recommend a gluten-free diet. Patients must avoid eating any foods

and ingredients that contains gluten including bread beer french fries pasta salad dressing soy sauce and even some soups (unless otherwise marked as gluten-free).

Experts worry however that going on these diets without explicitly needing to could be detrimental to a person's health as gluten-free foods are often nutrient-deficient.

#What is Hay fever? Simply put it's a misnomer. Doctors and researchers who specialize in allergies prefer the term allergic rhinitis

because hay is not the culprit and most allergies don't involve any fever. About 40 million Americans suffer from the condition whatever it's called.

Symptoms include stuffy and runny nose watery and itchy eyes sneezing wheezing and cough. There are dozens of substances that potentially can cause trouble in those of us who are susceptible to allergies

but trees are usually the first on the scene during spring allergy season says Jay M. Portnoy M d. president of the American College of Allergy Asthma and Immunology (ACAAI) and chief section of allergy

asthma & immunology at Children's Mercy Hospitals & Clinics in Kansas city Mo. Rain can provide some initial relief by reducing tree pollen counts

but it also can spur the growth of grass and weeds later in the spring and in early summer producing more pollen.

In many parts of the country this spring saw a perfect storm of allergy conditions.

A dry and cold winter followed by recent heavy rains has resulted in a slightly delayed onset of spring tree pollens said Paul Ratner M d. Medical Director of Sylvana Research in San antonio Texas

and a clinical assistant professor of medicine at the Long island College Hospital in Brooklyn N y. We are seeing many patients over the past several weeks both adults

and children with complaints that may be difficult for them to differentiate from a cold allergy or sinus problem.

Once they are diagnosed with a seasonal allergy an individual allergy treatment program can be prescribed for their relief Dr. Bassett said.

There has been prolonged a snow cover on the ground from Mid-november through Mid-march said ACAAI President-Elect Richard G. Gower M d. Marycliff Allergy Specialists in Spokane Wash.

1. Trees produce pollen the dust-like male reproductive parts of plants that cause most allergies.

and is a major cause of allergies. Evergreens also can be troublemakers. Cedar juniper cypress and sequoia trees have all been known to cause allergies

and if you're allergic to one you may be allergic to them all. Other suspects include elm trees

which are common in the eastern and midwestern regions birch trees olive trees sycamores and poplars including cottonwoods balsam

and aspen. 2. Grasses usually come along to stir up allergy symptoms after trees are through pollinating typically from late spring to early summer.

Common culprits are timothy grass Bermuda grass sweet vernal red top and some blue grasses. 3. Weeds are guilty of causing most of the allergy misery that occurs in the late summer and early fall.

Top on the list of offenders is ragweed which affects as many as 75 percent of all hay fever sufferers.

Ragweed is found in virtually every region of the United states and with 17 different species of the weed there's plenty of pollen to keep people sneezing

Melatonin's effects on sleep other hormones and cancer are the reason it has been studied ever since its discovery in the 1950s.

 Melatonin supplements are recommended also for sleep disorders due to side effects from beta-blockers (blood pressure medication) from stopping benzodiazepine drugs

Melatonin may also be given for insomnia linked to attention deficit-hyperactivity disorder ADHD) and autism in children.

so melatonin supplements seem like a logical fix for insomnia. There is a high demand for sleep aids especially in the U s. The National Health Interview Survey done in 2002

and again in 2007 found 1. 6 million US adults were using complementary and alternative sleep aids for insomnia.

Melatonin was a top choice. However melatonin dose more than influence sleep. Melatonin also regulates the start of menstruation the length of ovulation cycles and menopause according to the University of Maryland Medical center.

Melatonin supplements are purported to help bone loss and menopause symptoms. Melatonin levels are linked also to cancer in various ways.

Women with breast cancer typically have lower levels of melatonin than women who don't have it according to the University of Maryland Medical center.

Similarly men with prostate cancer typically have lower melatonin levels than men without prostate cancer.

Some studies show shift-workers with irregular sleep schedules have increased an risk of cancer according to the American Cancer Society.

Melatonin may also have antioxidant effects and stimulate white blood cells which attack cancer cells. Occasionally melatonin is used as a complementary medicine in cancer treatment for breast brain lung prostate head and neck or gastrointestinal cancer.

Melatonin is used sometimes to mitigate the side effects of chemotherapy including weight loss nerve pain weakness and a condition called thrombocytopenia.

A variety of other conditions are purported to benefit from melatonin supplements including Alzheimer s disease tinnitus depression chronic fatigue syndrome fibromyalgia migraine irritable bowel syndrome and epilepsy.

Supplement makers now market melatonin in pill liquid chewable or lozenge form. Melatonin supplements are sold doses that can range from 1 to10 milligrams.

Some dietary supplements contain so-called melatonin precursors which are converted into melatonin in the body. Â Melatonin is likely effective for several sleep issues research shows.

Studies show melatonin can encourage sleep in children who suffer from insomnia related to autism mental retardation and other central nervous system disorders according to the National institutes of health.

In 2001 double-blind study of 20 children with developmental disabilities showed all but two children fell asleep faster

when taking melatonin compared with a placebo. However melatonin did not change how long the children slept once they fell asleep according to the paper published in the Journal of Child Neurology.

Melatonin may possibly be effective for cluster headaches especially when taken in nightly doses of at least 10 milligrams according to the National institutes of health.

A movement disorder called tardive dyskinesia may be helped by melatonin. Additionally melatonin may decrease sunburn when applied to the skin as a cream before sun exposure.

Melatonin may also be effective for jet lag especially in preventing daytime sleepiness when taken to fall asleep earlier at night

However a systematic review of studies on melatonin and sleep disorders found melatonin supplements shorten the time it takes people to fall asleep faster by only about 12 minutes according to the paper published in 2005 in the Journal of General Internal medicine.

There is some evidence that melatonin may help cancer medications fight tumors and decrease the side effects of cancer treatment.

One study of cells in a test tube found melatonin reduced the growth of slowly-metastatic breast cancer cells meaning cancer cells that slowly start to spread to other types of tissue.

Melatonin also reduced the growth of non-metastatic breast cancer cells according to the paper published in 2001 in the journal Bioelectromagnetics.

 However the majority of evidence on melatonin and cancer has been done in relatively small studies according to the American Cancer Society.

More research needs to be done on effects of melatonin in cancer treatment or prevention. There is a lack of evidence about

Migraines and other headaches may not respond to melatonin nor may fibromyalgia menopausal symptoms osteoporosis irritable bowel syndrome or tinnitus.

However melatonin may cause side effects including headache daytime sleepiness short-lived depression symptoms stomach cramps dizziness and irritability.

so it may interfere with some cancer treatments according to the American Cancer Society. Patients currently undergoing cancer treatment should speak with their doctors before taking melatonin supplements.

Melatonin may increase the strength of the immune system which can cause problems for people with severe allergies rheumatoid arthritis lymphoma

and other conditions linked to overactive immune systems according to the American Cancer Society. People with immune system disorders should speak with a doctor before taking melatonin supplements as melatonin may weaken the effectiveness of immunosuppressants.

Melatonin may slow blood clotting so taking melatonin alongside medications that also slow blood clotting can lead to excessive bruising or bleeding.

Melatonin may also produce this side effect if taken with herbs that slow blood clotting such as angelica clove danshen garlic ginger ginkgo Panax ginseng red clover and willow.

Several drugs and treatments may interact with melatonin. Birth control increases melatonin levels in the body so taking melatonin supplements may cause high melatonin levels.

Taking melatonin supplements alongside sedatives such as benzodiazepines may cause excessive sleepiness. The drug fluvoxamine can increase the amount of melatonin absorbed by the body

therefore enhancing the effects and side effects of melatonin supplements. Similarly melatonin will enhance herbs with sedative effects such as calamus California poppy catnip hops Jamaican dogwood kava St john's wort skullcap valerian and yerba mansa.

Melatonin may increase blood sugar therefore decreasing the effectiveness of diabetes medications to lower blood sugar. Melatonin may also constrict blood vessels

which could be dangerous for people with high blood pressure or heart disease. Supplements that contain melatonin precursors such as L-tryptophan

and 5-HTP have not been proven effective in treating insomnia and there are safety concerns that they may be linked to debilitating condition called eosinophilia-myalgia syndrome (EMS).

Reliable research on the use of raspberry ketone for any health condition in humans is currently lacking.

Further high-quality research is needed said Catherine Ulbricht senior pharmacist at Massachusetts General Hospital in Boston

Low levels of adiponectin in the body are more common among  people who are obese and those with type 2 diabetes.

But for results that can be trusted doctors look for many human trials of a chemical with many participants.

The Natural Standard Research Collaboration Natural graded raspberry ketone as A c for evidence supporting claims for any health benefit.

The U s. Food and Drug Administration first categorized raspberry ketones as a Generally Recognized as Safe (GRAS) food additive in the 1960s.

So people taking drugs for diabetes should be monitored closely by their healthcare team. Raspberry ketone may also cause changes in body fat

Raspberry ketone may also interact with medicines such as those that regulate heart rate and cholesterol and hormones.
