Species:  Helianthemum   nummularium
Kingdom: Plantae
Order: Malvales

Synonyms: Helianthemum chamaecistus. Mill. Helianthemum vulgare. Gaertn.

Common Names:, Common RockroseSun Rose, Rock Rose

Habitat: Helianthemum nummularium is native to most of Europe. It grows on the basic grassland and scrub, to 600 metres.

Description:
Helianthemum nummularium is an evergreen tralling Shrub growing to 0.5 m (1ft 8in) by 1 m (3ft 3in) at a fast rate.
It is plant with loose terminal clusters of bright yellow, saucer-shaped flowers. In the flower centre is a tight cluster of orange stamens, which are sensitive to the touch, and spread outwards to reveal the tall stigma in the middle. The plant is common on chalk downs, and occasional in other grasslands, always on dry, base-rich soil. The wild species has yellow flowers, but garden varieties range from white through yellow to deep red.

Though the individual blooms are short-lived, the plant produces a mass of flowers through the summer. It needs a dry, sunny place, like a south-facing rockery or meadow. As the Latin name Helianthemum suggests, these are sun-flowers. This is a good nectar source for bees and there are several species of small beetle that feed on the foliage. Common rock-rose is also the food plant for the larvae of several species of moth and butterfly.

It flowers from May until July.

Hearing Loss

 

 

Introduction:
The gradual hearing loss that occurs as you age (presbycusis) is a common condition. An estimated one-quarter of Americans between the ages of 65 and 75 and around three-quarters of those older than 75 have some degree of hearing loss.

click & see

Over time, the wear and tear on your ears from noise contributes to hearing loss by damaging your inner ear. Doctors believe that heredity and chronic exposure to loud noises are the main factors that contribute to hearing loss. Other factors, such as earwax blockage, can prevent your ears from conducting sounds as well as they should.

You can’t reverse hearing loss. However, you don’t have to live in a world of quieter, less distinct sounds. You and your doctor or hearing specialist can deal with hearing loss by taking steps to improve what you hear.

Signs and symptoms
Signs and symptoms of hearing loss may include:

*Muffled quality of speech and other sounds
*Difficulty understanding words, especially against background noise or in a crowd of people
*Asking others to speak more slowly, clearly and loudly
*Needing to turn up the volume of the television or radio
*Withdrawal from conversations
*Avoidance of some social settings
How you hear:….click & see
Hearing occurs when sound waves reach the structures inside your ear, where the sound wave vibrations are converted into nerve signals that your brain recognizes as sound.

Your ear consists of three major areas: the outer ear, middle ear and inner ear. Sound waves pass through the outer ear and cause vibrations at the eardrum. The eardrum and three small bones of the middle ear  the hammer, anvil and stirrup   amplify the vibrations as they travel to the inner ear. There, the vibrations pass through fluid in the cochlea, a snail-shaped structure in the inner ear. Attached to nerve cells in the cochlea are thousands of tiny hairs that help translate sound vibrations into electrical signals that are transmitted to your brain. The vibrations of different sounds affect these tiny hairs in different ways, causing the nerve cells to send different signals to your brain. That’s how you distinguish one sound from another.

What causes hearing loss……....click & see
For some people, the cause of hearing loss is the result of a gradual buildup of earwax, which blocks the ear canal and prevents conduction of sound waves. Earwax blockage is a cause of hearing loss among people of all ages.

Most hearing loss results from damage to the cochlea. Tiny hairs in the cochlea may break or become bent, and nerve cells may degenerate. When the nerve cells or the hairs are damaged or missing, electrical signals aren’t transmitted as efficiently, and hearing loss occurs. Higher pitched tones may become muffled to you. It may become difficult for you to pick out words against background noise.

Ear infection and abnormal bone growths or tumors of the outer or middle ear can cause hearing loss. A ruptured eardrum also may result in loss of hearing.

Risk factors:
Factors that may damage or lead to loss of the hairs and nerve cells in your inner ear include:

Aging. The normal wear and tear from sounds over the years can damage the cells of your inner ear.

Loud noises. Occupational noise, such as from farming, construction or factory work, and recreational noise, such as from shooting firearms, snowmobiling, motorcycling, or listening to loud music, can contribute to the damage inside your ear.

Heredity. Your genetic makeup may make you more susceptible to ear damage.

Some medications. Drugs such as the antibiotic gentamicin and certain chemotherapy drugs can damage the inner ear. Temporary effects on your hearing — ringing in the ear (tinnitus) or hearing loss — can occur if you take very high doses of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), antimalarial drugs or loop diuretics.

Some illnesses. Diseases or illnesses that result in high fever, such as meningitis, may damage the cochlea.

Comparing loudness of common sounds
What kind of decibel levels are you exposed to during a typical workday? To give you an idea, compare noises around you to these specific sounds and their corresponding decibel levels:

Maximum job-noise exposure allowed by law
90 8 hours
95 4 hours
100 2 hours
105 1 hour
115 15 minutes

When to seek medical advice:
Talk to your doctor if you have difficulty hearing. Your hearing may have deteriorated if you find that it’s harder to understand everything that’s said in conversation, especially when there’s background noise, if sounds seem muffled, or if you find yourself having to turn the volume higher when you listen to music, the radio or television.

Screening and diagnosis:
At first, your doctor may perform a general screening test to get an overall idea of how well you can hear. Your doctor may ask you to cover one ear at a time to see how well you hear words spoken at various volumes and how you respond to other sounds.

To determine your ability to hear and the extent of your hearing loss, your doctor may refer you to a hearing specialist (audiologist) for hearing tests.

During more thorough testing conducted by an audiologist, you wear earphones and hear sounds directed to one ear at a time. The audiologist presents a range of sounds of various tones and asks you to indicate each time you hear the sound. Each tone is repeated at faint levels to find out when you can barely hear. The audiologist will also present various words to determine your hearing ability.

Treatment:
Hearing loss treatment depends on the cause and severity of your hearing loss.

If your hearing loss is due to damage to your inner ear, a hearing aid can be helpful by making sounds stronger and easier for you to hear. If you can’t hear well because of earwax blockage, your doctor can remove the wax and improve your hearing. If you have severe hearing loss, a cochlear implant may be an option for you.

Removing wax blockage……...click & see
Earwax blockage is a common reversible cause of hearing loss. Your doctor may remove earwax by:

*Loosening the wax. Your doctor uses an eyedropper to place a few drops of baby oil, mineral oil or glycerin in your ear to loosen the wax, then squirts warm water into your ear using a bulb syringe. As you tilt your ear, the water drains out. Your doctor may need to repeat the process several times before the wax eventually falls out.

*Scooping out the wax. Your doctor may loosen the wax, and then scoop it out with a small instrument called a curette.

*Suctioning out the wax. Your doctor uses a suction deviceto remove the softened wax.

Hearing Aids:

An audiologist can discuss with you the potential benefits of using a hearing aid, recommend a device and fit you with it.

Hearing aids can’t help everyone with hearing loss, but they can improve hearing for many people. The components of a hearing aid include:

*A microphone to gather in the sounds around you
*An amplifier to make sounds louder
*An earpiece to transmit sounds to your ear
*A battery to power the device
The louder sounds help stimulate nerve cells in the cochlea so that you can hear better. Getting used to a hearing aid takes time. The sound you hear is different because it’s amplified. You may need to try more than one device to find one that works well for you. Most states have laws requiring a trial period before you buy a hearing aid, making it easier for you to decide if the hearing aid helps.

Hearing aids come in a variety of sizes, shapes and styles. Some hearing aids rest behind your ear with a small tube delivering the amplified sound to the ear canal. Other styles fit in your outer ear or within your ear canal.

Cochlear implants
If your hearing loss is more severe, often due to damage to your inner ear, an electronic device called a cochlear implant may be an option. Unlike a hearing aid that amplifies sound and directs it into your ear canal, a cochlear implant compensates for damaged or nonworking parts of your inner ear. If you’re considering a cochlear implant, your audiologist, along with a medical doctor who specializes in disorders of the ears, nose and throat (ENT), will likely discuss the risks and benefits with you

The components of a hearing aid are held in a small plastic container called the casing. All hearing aids use these common parts to help conduct sound from your environment into your ear. But different styles and different technologies make for many different types of hearing aids from which to choose.

Hearing aid styles vary by size. Though smaller styles may be less noticeable, they’re generally more expensive and have a shorter battery life. An audiologist can show you the various styles of hearing aids to help you decide which is best for you.

A microphone (1) picks up sounds. The sounds travel through a thin cable to a speech processor (2). You can wear the processor on a belt, in a pocket, or behind the ear. The processor converts the signal into an electrical code and sends the code back up the cable to the transmitter (3) fastened to your head. The transmitter sends the code through your skin to a receiver-stimulator (4 and 5) implanted in bone directly beneath the transmitter. The stimulator sends the code down a tiny bundle of wires threaded directly into your cochlea, the snail-shaped primary hearing organ. Nerve fibers are activated by electrode bands on this bundle of wires. Your auditory nerve carries the signal to your brain, which interprets the signal as a form of hearing.

Newer cochlear implants use an externally worn computerized speech processor that you can conceal behind your ear. The speech processor sends signals to a surgically implanted electronic chip that stimulates the hearing nerve of deaf people.

causes of hearing loss

Hearing loss prevention consists of steps you can take to help you prevent noise-induced hearing loss and avoid worsening of age-related hearing loss:

  • Protect your ears in the workplace. Specially designed earmuffs that resemble earphones can protect your ears by bringing most loud sounds down to an acceptable level. Foam, pre-formed, or custom-molded earplugs made of plastic or rubber also can effectively protect your ears from damaging noise.
  • Have your hearing tested. Consider regular hearing tests if you work in a noisy environment. Regular testing of your ears can provide early detection of hearing loss. Knowing you’ve lost some hearing means you’re in a position to take steps to prevent further hearing loss.
  • Avoid recreational risks. Activities such as riding a snowmobile, hunting, and listening to extremely loud music for long periods of time can damage your ears. Wearing hearing protectors or taking breaks from the noise during loud recreational activities can protect your ears. Turning down the volume when listening to music can help you avoid damage to your hearing.

Coping skills

Try these tips to communicate more easily despite your hearing loss:

  • Position yourself to hear. Face the person with whom you’re having a conversation.
  • Turn off background noise. For example, noise from a television may interfere with conversation.
  • Ask others to speak clearly. Most people will be helpful if they know you’re having trouble hearing them.
  • Choose quiet settings. In public, such as in a restaurant or at a social gathering, choose a place to talk that’s away from noisy areas.
  • Consider using an assistive listening device. Hearing devices, such as TV-listening systems or telephone-amplifying devices, can help you hear better while decreasing other noises around you.

Abnormal Nipples

There are two main types of nipple abnormality: retraction into the breast and disorders affecting the skin on or around the nipple. although these abnormalities are most often caused by minor problems that are easily treatable, any changes in the condition of the nipples should receive medical attention because, in rare cases, they may indicate breast cancer....click & see

Possible causes:
Inversion of the nipples may occur during puberty if the breasts do not develop properly. this type of inversion is usually harmless, although it may later make breast-feeding difficult. Nipple inversion may also occur in the previously normal breast as a result of inflammation of the milk ducts behind the nipple. This condition most often affects women who are breast-feeding. Changes in the structure of the breasts as they age may cause the nipple to be drawn into the breast in older women. Less commonly, nipple inversion that develops in adulthood may be due to breast cancer.

\Many women develop fine cracks and tender areas on their nipples during the first few weeks of breast-feeding. these cracks are most often the result of the baby not taking the whole nipple into his or her mouth properly when feeding. leaving your nipples wet after a feed can also cause them to become sore and cracked. cracked nipples often cause stabbing or burning pain as the baby starts or stops feeding and may become infected, causing inflammation of the breast tissue.

Dry, flaky patches of skin that occur on or around both nipples may be due to eczema. eczema is usually itchy and tends to occur in several sites on the body. however, occasionally, skin changes on the nipples that resemble eczema are in fact caused by paget’s disease of the breast, a rare form of cancer that originates in the milk ducts. unlike eczema, paget’s disease rarely develops on both nipples and does not heal. this type of breast cancer often causes soreness and bleeding from the nipple and is often associated with a breast lump.

What might be done?
Your doctor will examine your breasts, paying particular attention to your nipples. if nipple inversion has occurred in adulthood but is not related to breast-feeding, your doctor may arrange for ultrasound scanning or breast x-rays to look for breast abnormalities. if a breast lump is found, cells or fluid may be taken from it using a needle and syringe and examined under the microscope for cancerous cells. If you have a persistent rash on or around a nipple, your doctor may take a skin sample to look for cancerous cells.

Occasionally, it is possible to correct nipple inversion that has been present since puberty by gently drawing the nipples out between your thumb and forefinger every day for several weeks. Suction devices, such as nipple shells, which are temporarily worn in your bra, can also help draw out the nipple.

If your nipples have become cracked, washing and drying them carefully and applying a moisturize may help. make sure that you wash the moisturizer off before breast-feeding. You should also avoid plastic-lined breast pads which may become damp and encourage infection. infection is usually treated with antibiotics and eczema can be improved by hydrocortisone cream.

If cancer of the breast is discovered, you will be referred to a specialist for treatment, and further tests, including blood tests and x-rays, may be done to find out if the cancer has spread to other body organs. if paget’s disease is diagnosed, the affected skin will be surgically removed along with surrounding tissue. if a lump is present, treatment can include surgery, radiation therapy or chemotherapy.

Lost memories can be restored

Mental stimulation and drug treatment may help people with brain ailments such as Alzheimer’s disease regain seemingly lost memories, according to research published on Sunday.Scientists used two methods to reverse memory loss in mice with a condition like Alzheimer’s — placing them in sort of a rodent Disneyland to stimulate their brains, and also using a type of drug that encourages growth of brain nerve cells.

CLICK & SEE

Neuroscientist Li-Huei Tsai of the Howard Hughes Medical Institute and the Massachusetts Institute of Technology said such methods might yield similar benefits in people with Alzheimer’s disease or other types of dementia that rob them of their memory and ability to learn.

“We show, I believe, the first evidence that even if the brain suffered some very severe neurodegeneration and the individual exhibits very severe learning impairment and memory loss, there is still the possibility to improve learning ability and recover to a certain extent lost long-term memories,” Tsai said.

Tsai said if apparently lost long-term memories could be retrieved, this suggested the memories had not been actually erased from the brain. Instead, she and colleagues reported in the journal Nature, the memories probably remained in storage but could not be accessed or retrieved due to the brain damage.

The researchers used genetically engineered elderly mice in which they were able to activate a protein that triggered brain pathology very much like that of people with Alzheimer’s, with atrophy and loss of nerve cells.

Previous research has shown that regular mental stimulation such as reading or playing a musical instrument may reduce one’s risk for Alzheimer’s. And a stimulating environment also has been shown to improve learning in mice.

In one part of their study, the researchers took mice out of their usual bland cages and placed them in a sort of mouse playground loaded with an ever-changing assortment of colorful toys, treadmills and other mice.

The researchers previously had used a “fear-conditioning” test — placing mice in a chamber and delivering a mild electric shock to their feet — to establish an enduring memory.

Mice with Alzheimer’s-like brain damage put in the stimulating environment could remember that shock test far better than similar animals kept in standard cages. The playground mice also were better at learning new things than those kept in cages. After exploring the biological mechanism behind the improvement in mice placed in the enriched environment, the researchers tested on the mice a class of drugs called histone deacetylase, or HDAC, inhibitors.
