Beware, Mobile Can Reduce Male Fertility

A study has found that mobile phone use can lead to low sperm quality. As a result, decreased male fertility.

Men who have been diagnosed to have poor sperm quality and were trying to have children should limit their cellphone use. Researchers have found that while the use of mobile phones increase in circulating testosterone in the body, it also can cause low sperm quality and fertility decline.

"Our findings are a bit confusing," said Rany Shamloul, principal investigator who is a postdoctoral fellow at the Department of Pharmacology and Toxicology.

"We're hoping to find different results, but we found the results confirmed that there may be some mechanism that mengadung intrigue in the process," he added, as quoted Health24, Monday (23/05/2011).

Affect hormone levels

The research team found that men who reported high levels of use of their phones have the levels of circulating testosterone are also high. But it turns out, the level of luteinizing hormone (LH)-an important reproductive hormone released by the pituitary gland in the brain-becomes lower.

The researchers hypothesize that the electromagnetic waves (EMW) emitted by mobile phones have dual action on hormone levels and male fertility.

EMW can increase the number of cells in the testes which produce testosterone by lowering levels of LH released by the gland in the brain. EMW also hinder circulation changes testosterone into a form that is more active and powerful that is associated with sperm production and fertility.

Researchers hope, in-depth and sustained research is needed to determine appropriate ways how EMW affect male fertility.

taking painkillers raise blood cancer

Taking painkillers raise blood cancer. painkiller commonly consumed as a fever or when a cold. However, you should be wary because of the use of this medicine regularly and long term will increase the risk of suffering from blood cancer.

Please be careful for those who are routinely taking painkillers. Recent research shows that excessive use of acetaminophen, a painkiller that most behavior is also known as Tylenol in the United States and paracetamol in Europe may increase the risk of blood cancer.

However, this risk is relatively low and has not been confirmed by scientists regarding the role of these drugs to cause the deadly disease. This finding evidence of complex twists associated link between painkillers and cancer, and suggests that acetaminophen may be different from other drugs.

Previous research found that aspirin use can reduce the likelihood of dying from colon cancer, but increases the risk of bleeding. However, this conclusion is not yet clear, whether it will trigger the blood cancer or hematologic cancer.

"Before this study, there is very little evidence that aspirin reduces the risk of hematological cancers," said Emily White from the Fred Hutchinson Cancer Research Center in Seattle, United States, who worked on this latest research as reported by Reuters.

There are several clues that mention that the drug acetaminophen, on the other hand can increase the risk of cancer. However, it is based on individual cases of suffering from blood cancer. Studies examining the patients one by one is considered not as strong as this new series, following in the footsteps of a large population of healthy persons from time to time.

"We used a prospective study," said White.

However, he cautioned, there is no evidence that acetaminophen causes cancer and this new conclusions need to be confirmed before being used in every treatment decision. Previous studies have linked acetaminophen with asthma and eczema. However, scientists still disagree, whether the drug actually causes or simply "witness" who was not guilty.

The new study is also not free from the same limitations that people who consume lots of painkillers to deal with medical problems that lead to cancer throughout his life.

The researchers followed almost 65,000 middle aged men and women in Washington State. At first, they asked for data from participants about the use of painkillers during the last 10 years and ensure that he is not suffering from cancer (except skin cancer).

During an average of about six years, 577 people or less than 1 percent of participants-developing cancer that involves blood cells. Examples of such cancers include lymphoma and myelodysplastic syndrome (MDS). More than 9 percent of people who develop cancer due to use of one high dose of acetaminophen, compared with only 5 percent of those who are not sick.

After taking into account other factors such as age, arthritis, and family history of certain blood cancers, excessive acetaminophen users almost twice the risk of the disease.

"Someone who is aged 50 years or older have about the risk of 1 percent in ten years of getting one of these cancers," said White.

"Our study shows that if you are using acetaminophen at least four times a week for at least four years, will increase the risk of (blood cancer) to around 2 percent," he continued.

No other painkillers, including aspirin and ibuprofen, the risk associated with this blood cancer. Dr. Raymond DuBois, cancer prevention expert at the University of Texas MD Anderson Cancer Center in Houston, United States, say, acetaminophen works very differently than other painkillers that can be expected to have different effects on cancer.

"However, it is surprising to see that the use of acetaminophen increases the risk of blood cancer," said DuBois, who was not involved in this research.

McNeil Consumer Healthcare, a subsidiary of Johnson & Johnson that sells Tylenol, did not respond to requests for comment on these findings. White asserted, is too early to make recommendations based on this new research and no painkillers are free from side effects.

"Long-term use of any drug will cause side effects. You have to weigh the benefits against risks of all drugs, "he said.

Common blood cancer or leukemia is also called a type of cancer that attacks white blood cells produced by bone marrow (bone marrow). This bone marrow in the human body produces three types of blood cells, including white blood cell (functioning as immune against infection), red blood cell (function to bring oxygen into the body), and platelets (small part of blood cells that help the clotting process blood).

Leukemia is generally appear in a person since his childhood. A person with leukemia will show some symptoms, such as susceptible to infectious diseases, anemia, and bleeding.

5 Bahaya akibat kurang tidur

Menurut sebuah penelitian ada banyak bahaya yang ditimbulkan bagi tubu, jika kurang tidur. berikut 5 bahaya akibat kurang tidur :

Rentan terhadap penyakit jantung

Wanita yang secara teratur mendapatkan kurang dari lima jam tidur tiap malam secara signifikan lebih mungkin menderita hipertensi, pemicu utama penyakit jantung, menurut sebuah studi baru-baru ini. Bila Anda kurang tidur, tubuh akan memproduksi hormon stres lebih banyak dan zat-zat lain yang meningkatkan peradangan, yang dapat meningkatkan risiko penyakit jantung dan stroke.

Mengembangkan diabetes


Menurut penelitian yang diterbitkan dalam Archives of Internal Medicine, mereka yang memeroleh kurang dari lima jam tidur per malam memiliki 2,5 kali risiko terkena diabetes dibandingkan dengan mereka yang tidur 7-8 jam. Alasannya, pengurangan jam tidur secara signifikan mengurangi kemampuan Anda untuk mengatur kadar gula darah.

Emosi tidak stabil


Para ilmuwan telah menemukan bahwa kurang tidur membuat amigdala (bagian dari otak yang memproses emosional) masuk korteks prefrontal (bagian dari otak yang mengatur penalaran) dan menjadi tidak aktif, membuat mood Anda kurang stabil dari biasanya.

“Kurang tidur membuat otak tidak mampu mengolah pengalaman emosional dan menghasilkan respons yang rasional,” kata peneliti Matthew Walker PhD.

Lebih sering sakit

Saat tidur, tubuh Anda memproduksi sitokin, zat kimia yang membantu sistem kekebalan tubuh melawan infeksi dan penyakit.

"Tidur tidak hanya memengaruhi seberapa baik tubuh Anda melawan infeksi, tetapi juga menentukan seberapa baik tubuh memroduksi antibodi setelah vaksinasi. Penelitian menunjukkan bahwa orang yang kurang tidur memproduksi antibodi flu lebih sedikit setelah menerima vaksin flu," kata Matthew.

Kegemukan

Penelitian menunjukkan bahwa orang yang mendapatkan kurang dari tujuh jam tidur malam cenderung 30 persen menjadi lebih gemuk. Kurang tidur mengubah aliran hormon yang mengatur rasa lapar dan kenyang, yang dapat menyebabkan Anda makan lebih banyak.
