A new study suggests

3CHTN-306

(HealthDay News)– According to a new study, Parkinson’s patients, who struggle against tics, spasm, tremors that usually occur when main medications is diminished, may be helped by a new drug.

Istradfeylline helps nerve and brain signals bypass and the spoiled dopamine system that be the cause of Parkinson. In a trial 395 people with Parkinson who used levodopa (a well-known Parkinson’s drug) were found with 24% higher “off” than those who were using Istradfeylline. The “off” has been defined as a time when physical symptoms begins to appear after wearing off the drug levodopa.Similarly, in a group studied who took a placebo showed 10 % drop in “Off” time.

The results suggest that istradefylline works effectively if it is used as an add-on therapy to other drugs that are used for Parkinson’s symptoms. The thing that is noteworthy is that this drug may improve “off” time in a population that is consisted of more than 90% of patients that are already being given two or more drugs. It was stated by study author Dr. Mark Stacy of Duke University Centre in Durham, N.C.

These findings have been published in the June issue of Neurology .One worth mentioning thing is that theses may not prove helpful to decrease the sufferings of Parkinson’s patients at least in the U.S. as U.S. food and Drug Administrator has not approved the drug yet, calling its effectiveness inadequate. In the meanwhile, Kyowa Pharmaceuticals Inc, the drug’s manufacture has stopped manufacturing of the drug in North America.

It is worth mentioning that the study has been funded by Kyowa Pharmaceutical.

Istradefylline is a new drug treatment to Parkinson. Parkinson is generally treated with medications that hone with dopamine but the effectiveness of these drugs diminishes after some time. To open communication with the brain, Istradefylline seems to connect with receptors besides dopamine.

High levels of ghrelin (a hormone) have antidepressant effect, a new study suggests

The levels of a hormone known as ghrelin greatly increase when our bodies want more calories for themselves. Ghrelin is known as a hunger inciter but according to a new research it may be a reaction of its basic job as a stress-buster.
Researchers used different methods, like prolonged calorie restriction, ghrelin injection and genetic modification, to manipulate ghrelin levels in mice.

It was found that Mice with limited ghrelin activity looked depressed and when they were pushed into water, they didn’t make any effort to swim and in maze they stickled to the entryway. They were also more involved in themselves when they were placed with other mice. And it was also noted when a low-dose of antidepressant was given to them, these behaviors began to get reverse. …Click here to read more

According to federal health officials reports, though the rates of new skin cancer cases has become steady in younger men, the number of women who are being diagnosed with skin cancer is on increase.

The U.S. government cancer statistics for the period 1973 to 2004 suggest that there has been a 50 % increase in new melanoma cases in younger women since 1980 but there was no increase for younger men during this period.

“It’s quite alarming” stated Mark Purdue who made the analysis for these statistics and it was published in the journal of Investigative Dermatology. “The things we are noticing in young adults at that time could predict a greater number of melanoma cases in older women.” …Click here to read more

The New York Times Sunday investigated how the Genentech cancer drug Avasting shows both the optimisms and predicaments of modern medication because it offers incremental paybacks for cancer patients, the drug is expensive and concerns have been greater than before about its security and efficacy.

The drug which is observed as a wonder-drug for its knack to stop blood supply to cancers costs as much as $100,000 per annum and had deals of $3.5 billion last year. Research expresses that drug prolongs the lives of victims with colon, lung and breath malignancy. Some patients and physicians say Avastin perks up the quality of life allowing patients to do daily functions devoid of tiredness, but such benefits are not easy to substantiate, reported by Times.

These charges have been rejected by the sunscreen makers, however. The Environmental working Group (EWG) investigated almost 1,000 branded sunscreens and found that every fourth out of five either proved ineffective to protect against harmful UV rays or had some skin damaging chemicals.

Different well known brands including Coppertone, Neutrogena and Banana Boat were at top among the bad delinquents, EWG claimed in their report that has been published on their website on 2nd July. …Click here to read more

Blood cells that work to heal wounds may also develop suitable condition for cancer cells to spread, stated U.S. researchers, Tuesday.

According to the scientists fibrocytes, blood cells that originate from bone marrow, may explain how healthy cells become environmental for cancer.

“It has been known before that cancer cells don’t have an easy access to healthy tissue,” stated Dr. Hendrik van Deventer of the University of North Carolina at Chapel Hill.

“Though we haven’t recognized this cell, yet we believe it may be a fibrocyte” van said

While working with genetically engineered mice Van first time suspected fibrocytes as these were lacked the cell receptor CCR5, which is a cellular gateway that assists controlling the movement of cells through the body and it is also the similar gateway that is used by the human immunodeficiency virus that leads towards AIDS after accessing to immune cells.

The genetically engineered mice that also suffered the skin cancer melanoma were inclined to receive less metastatic tumors than other normal mice with the skin cancer. In their efforts to make these altered mice form more tumors, Van and his team methodically injected these altered mice with different kinds of cells from normal mice.

We tested it with a variety of different cells and found that fibrocytes working, Van said.

Fibrocytes move in the bloodstream to injured areas in healthy human and they develop such changes as are suitable for wounds to heal but according to van these changes may tend to help cancer growth.

Bone building drugs show some hopes as a wider anti-cancer drugs

CHICAGO—There is a possible new way to fight against breast cancer as doctors are quite excited to find that a drug which is used to avoid bone loss during breast cancer cure may significantly lower the risk of reoccurrence of breast cancer.
Zometa and other bone-building drugs known as bisphosphonates show some hope as a wider anti-cancer drugs in this first large study. The cancers that already spread to the bone are treated by Zometa, a drug developed by Novartis AG.

1,800 premenopausal women who were getting hormone treatments for their initial stage breast cancer included in this new study. It was found that Zometa reduced almost one-third chances that the cancer would return. …Click here to read more

The AAD said that one in every five Americans would develop skin cancer a moment or two during his/her life span.

The most prevalent types of skin cancer are squamous cell carcinomas and basal cell, but they are easy to treat if detected near the beginning.

It is investigated by the team of skin surgeons that more than 75% skin cancer deaths are occurred due to melanoma which is a very dangerous tumor.

Melanoma is the most insidious types of cancer which is normally occurred in the people by 25 to 29 years. Melanoma is generally developed in the trunk and it is the second most widespread form of cancer among people aged by 15 to 29 years old. Dermatologists recommend this might happen due to high-risk-tanning-behaviors.

Meanwhile, The AAD said that five-year survival rates among people aged by 10 to 39 years old observed in melanoma over 90%. Therefore, it is said, Melanoma is likely to impact something like 1 in ever 58 American people during their lifespan.

There are more risk factors of melanoma observed in Caucasian men and women, and men over 50.

If a patient’s melanoma is diagnosed and treated before it spreads and swells to the lymph nodes his/her probability of surviving over five years is 99%.

The AAD confidently says there will be around 116,500 melanoma cases this year including 54,020 noninvasive (in situ) and 62,480 insidious (34,950 men and 27,530 women). It is investigated that around 8,420 people will be died of due to melanoma like 5,400 men and 3,020 women in 2008 and it is projected that about one death from every sixty-two minutes will be soon occurred in melanoma people.

The World Health Organization (WHO) has conducted a wide survey regarding the melanoma which exposed that about 65,000 people die of due to melanoma which is caused due to ultraviolet radiations from the scorching sunlight.

WASHINGTON : A drug made of using nanotechnology and a fungus tarnished some laboratory experiments might be widely effective against a range of cancers, The U.S researchers said on Sunday.

The drug known Lodamin had been improved in one of the last experiments investigated by Dr. Judah Folkman, a cancer researcher who died in January. Folkman led the idea of angiogenesis therapy ravenous tumors by holding over them from rising blood supplies.

Lodamin is an angiogenesis inhibitor that Folkman’s team has been running just right for 20 years. Writing in the journal Nature Biotechnology, his colleagues said they developed a formula working as a pill with no side-effects. …Click here to read more
