Worms to cure skin cancer
An international investigation has discovered one of the mechanisms involved in the renovation of the cuticle of the worm Caenorhabditis elegans, opening new lines of study in the field of anti aging skin in humans and in healing and healing wounds.
The study noted that the molting process in this worm is associated with changes in the oxidation state of proteins present in the cuticle.
By blocking the activity of these proteins, the old cuticle is not weakened enough to break the animal, and just dying inside.
It could also help in treating skin cancers and the development of treatments for nematodiasis, parasitic diseases caused by nematodes (a type of worm as studied in this research) and widespread in the developing countries.
The aging in living organisms is caused by the reduced ability of cells to repair oxidative damage that accumulates throughout life.
The molting process in this worm is associated with changes in the oxidation state of proteins present in the cuticle.
The application of glutathione, a molecule present in all living organisms and regulates cellular oxidation balance favors the move and moving to the next larval stage, as it helps the worm to degrade the old cuticle and leave her.
If we discover what other cuticle proteins are involved in oxidation processes, we could come up with new ways to treat these diseases.
One in three gets dangerous rays
In Spain, one in three people taking a sun bathing during the times that is most dangerous between 12 am and 4 pm. Delial Garnier and the Association of European Cancer Leagues (ECL) confirmed this figure three a thorough study.
This study also revealed that two percent of Europeans have or have had skin cancer. While 79 percent of Spanish has this evil among their top concerns, even in women this alarm is reflected in a 81 percent of respondents.
Another alarming figure says that only 36 percent of Spanish applied sunscreen against UV rays. However, they recognize that not re-apply the cream all day. When you know that it is necessary applications throughout the day. But the most dangerous thing is to know that 10 percent do not use sunscreen at all.
As for skin care of children, have also revealed worrying figures. As the 34 percent applies protective their children who are not specially designed for sensitive skin .
All in all a calculation that arouses hope is that 41 percent of Spanish in the sun less than it did before. The 46 percent is still doing the same and only 13 confessed that over time in the past.
New ways to fight skin cancer
One of the cancers most common in the world is the skin. It is estimated that in Spain there are six to seven cases per hundred thousand inhabitants and in Australia the figure rises to 42 in every hundred thousand. That’s why two medical institutions are innovating in how to detect and combat this type of cancer.
The first is the Clinical Hospital Virgen de la Victoria, where in a relatively short time has been using a new operating system. This is the Mohs micrographic surgery. With it you can access hard to reach places such as the nose or eyelids.
Is that while the surgeon operates, the anatomist, the tissue removed. In this way. He begins to cut the fabric of downtown, where large percentage of cancer. Then he begins to cut out circles to remove the skin compromised. When the anatomist realize that you have removed all the cancerous tissue and that there is only healthy skin line stops the procedure.
Also, the Carlos Haya Hospital has a unit of teledermatology . This unit is responsible for digitally photograph the area believed to be cancer. This photograph is emailed to a specialist medical center for diagnosis. This will reduce the detection time and you can start, if you require a treatment much faster and therefore more expectation of success.
Skin cancer symptoms
The symptoms of non-melanoma includes basal cell carcinoma and squamous cell carcinoma.
Skin cancer “nonmelanoma” is the most common and also less dangerous than the “melanoma.”
Symptoms of skin cancer are:
- Small lump or mole, waxy, pale glossy and smooth.
- A firm red lump.
- A spot or sore that bleeds or does not heal.
- Any kind of growth that is suspicious
Tumors usually are painless, so it is recommended that skin self-examination routinely to detect changes in the skin and an annual review by the health care clinician.
When a mole is suspected irregular or lump should immediately consult a specialist.
Also, people with a family history of cancer or who are at increased risk of developing pre-emptively should consult a dermatologist.
Anyone can develop skin cancer, but there are some who are more likely because they have special features such as:
- People who have freckles
- The clear skin tones
- Those who burn easily.
- People with blue eyes, like green and blue.
- People who have red or blond hair natural.
- Those who spend time outdoors
- Those exposed to the sun continuously and without adequate protection.
- When a family history of suffering from cancer of any of the two groups.
Skin Cancer
The two types of skin cancer are basal cell cancer and squamous cell cancer. Generally, this type of disease on the face, neck, hands, arms and head. Another type of skin cancer more dangerous but less common than the so-called melanoma.
Anyone can get skin cancer, however there are some behaviors that may increase the chances of suffering, including:
• They spend much time basking in the sun and do it without proper protection.
• People of skin and eyes.
• Family history.
• People over 50 years of age.
Any suspicion or indication on the skin or at the slightest change in appearance in the epidermis should be the referral.
When detected early there are greater chances that the treatment is effective and achieving a complete remission of cancer.
To protect yourself it is advisable not to sunbathe at the times where its rays are strongest (between 10 am and 4 pm), always using the right sunscreen and sunglasses also provide 100% protection .
It is important to monitor and check the skin regularly for any changes in either birthmarks, moles or spots , as these can be a sign of skin cancer.
Basal Cell Carcinoma
Gorlin syndrome is a genetically determined disease in which there are multiple basal cell carcinomas with ‘pits’ on the palms of hands and soles of the feet and other systemic disorders such as jaw cysts, rib and vertebral abnormalities, among others.
The pits (circular punctate lesions of one or two mm) are presented in soles and palms. Are due to an alteration in the maturation of the cells that form this special skin (palmoplantar). In particular, result from the premature desquamation of keratin immature resulting from the delay in the maturation of epidermal basal cells. In some patients, at the base of the lesions detected small basal cell carcinomas.
You should never remove carcinomas with liquid nitrogen or any other system discussed previously. It should be a histologic diagnosis of carcinoma before treating. There are currently no invasive diagnostic methods (confocal microscope) to avoid taking a biopsy. The confocal microscope is a method for analyzing cells in situ on the patient, and non-invasive (no need for skin or stitches).
