Scientists Discovered Prospective Treating Compounds For Protozoa Infections

Protozoa Infections“Cryptosporidium parvum”, a typical protozoa-infection that causes acute, watery, and non-bloody diarrhea in small children in developing countries and immune-compromised patients is becoming a concern for scientists the world over. This infection may also cause anorexia related watery diarrhea in HIV infection. Such an infection will result in to nausea, vomiting, and abdominal pain.

Resistivity property of these protozoa to the water chlorination has caused massive epidemic in the United States. Scientists have also expressed that it has attained a status of a ‘prospective bio-terrorism agent’. There are neither vaccines nor effective drugs available to respond to these multiple threats to human health.

A major breakthrough has been achieved as scientists at the ‘Brandeis University’ and the ‘University of Georgia’ has been successful in identifying the lead compounds that can resist the attacks of this protozoa. In the published details of this research in the journal “Chemistry and Biology”, the scientists hope that their findings will pave the way for further development of an effective antibiotic treatment.

Alzheimer’s is a Hindrance to Driving Abilities

Alzheimer Alzheimer’s Disease (AD)’ is the most common form of dementia among older people. It is a brain disorder that seriously affects a person’s ability to carry out daily activities. It is a progressive and fatal brain disease slowly effecting thought, memory and language serious enough to interfere with daily life.

A recent study by researchers at ‘Rhode Island Hospital and Brown University’ finds that people with ‘Alzheimer’s Disease (AD)’ experienced more accidents and performed more poorly on road tests compared to drivers without cognitive impairment. The study is published in the January 23 edition of the journal “Neurology”, the medical journal of the ‘American Academy of Neurology’. This stems out of the fact they show problems with memory, thinking and concentration.

The study included 128 individuals. Out of these individuals, 84 persons were suffering with early AD and 44 age-matched control subjects without cognitive impairments. Drivers with early AD were enrolled in this study and followed every six months over two to three years. While the study does confirm previous reports of potentially hazardous driving in persons with early AD, it also indicates that some individuals with very mild dementia can continue to drive safety for extended periods of time. The study also built the relationship through self-reports, family reports and a standardized road test.

Aspirin May Help Reducing Lung Cancer Risks in Women

Lung Cancer‘Aspirin’ can be an effective medication for the women as an inexpensive lung cancer chemoprevention though causing few side effects. A recent research study findings give a clear indication with clinical evidences.

This specific case-control study involved almost 581 African-American and Caucasian women with and without’ non-small-cell lung cancer (NSCLC)’. Findings of the study revealed that the regular use of aspirin helps in reducing the risk for the disease by a significant 34% rate among women.

Certain previous specific research studies also indicated that aspirin and other similar ‘non-steroidal anti-inflammatory drugs (NSAIDs)’ have potential for decreasing the risk for NSCLC. Some of the other studies however, established that the results of this degree are not quite possible.

Scientists Discover Brain Mechanisms Governing Exploration Decisions

BrainScientists have been successful in identifying a particular region in our brain that controls typical decision making process of the brain. It will now be possible to understand how a person decides of halting the midnight exploration of refrigerator and enjoying the leftover chicken legs. The mechanism governing such decisions of the brain leading to malfunction in addiction and mental illness would be immensely helpful in designing the further treatments, say the researchers.

Emmanuel Procyk and his colleague researchers have published the findings of this research in the January 24, 2008, issue of the journal” Neuron”.

Researchers conducted experiments on monkeys and required them to spend time in exploration targeting a ‘juice reward’ with a choice of tough targets on a computer screen. Immediately upon identifying their ‘juice reward’, the monkeys were given a period for touching the reward many times in order to explore the chances of getting more rewards.

Vitamin D Supplements Could Be More Harmful

VitaminDVarious diseases have long been associated with the low blood levels of ‘vitamin-D’. It is general assumption worldwide that the ‘vitamin-D’ is a good supplement and helps preventing many diseases. Scientists however, feel that this existing assumption that hundreds of genes are dependent on vitamin D now must be given a re-consideration in the light of new study.

Dr.Trevor Marshall, Professor at the ‘Murdoch University School of Biological Medicine and Biotechnology’, Australia has explained this requirement at length in his research published in the current issue of the journal “BioEssays“.Dr. Marshall explains that the evidences indicate thatincreased vitamin D intake affects much more than just nutrition or bone health”. He further says that the “Vitamin D Nuclear Receptor (VDR)” acts in the repression or transcription of hundreds of genes”. Such a condition includes the genes and they get associated with diseases and disorders of various types including cancers and multiple sclerosis.

Scientists Discovered Gene Helping Faster and Scar- Free Healing

Damage CellsWounds can be healed faster and scaring can be reduced substantially if one of the genes is suppressed. This specific gene normally switches on within the wounded cells and cause scars.

This recent study finding of scientists at the ‘University of Bristol’ has several implications for millions of people who are suffering from organ tissue damage problems just because of some illness or abdominal surgery. It would also help many others who are wound victims. Findings of this research study will be published in the “Journal of Experimental Medicine” on 26 January.

Immediately upon damage occurs to the skin there is a formation of blood clot. Cells present below the wound start repairing the damage and this normally results in to scarring.

Mobile Phones Interfere With Quality of Sleep

Sleep A new study by researchers in the US and Sweden suggests that using a mobile phone could interfere with your quality of sleep.Use of mobile phones interferes with the quality of sleep. A recent research conducted in the US and Sweden confirmed this finding. Researchers at the ‘Wayne State University’ in US and the ‘Karolinska Institutet’ in Sweden published the findings of this study in a peer reviewed online journal “PIERS Online”.

A group of 71 people, 36 women and 35 men took part in this study. Out of these 22 men and 16 women reported strong symptoms attributing to the disturbances in sleep with the use of mobile phones. Researchers collected data for symptoms of headache, mood, cognitive function, and electro-encephalographic recordings.

Participants were exposed to the mobile signals on an 884 MHz GSM wireless communications band and were directed to the left hemisphere of the brain, giving an average exposure of 1.4 Watts/kg including periods of DTX and Non-DTX.

Bionic Eyes: A Dream to Come True Soon

Binoiceye1“Bionic Eyes” may not be limited to the imaginative reflections in some movies only. Creating virtual visions and displays is very soon going to be a reality. The day is not far off when visual aids will be available to help vision -impaired people. Future lies with the holographic driving control panels and surfing the web midair with no visibility to others.

Scientists have now been successful in developing a microscopic technology for creating an artificial virtual display system or the “bionic Eyes”, as popularly known.

For the first time ever the manufacturing technique was brought to the microscopic level by the engineers of the University of Washington. It was applied for making a combination of a flexible and biologically safe contact lens with an imprinted electronic circuit and lights. The contact lenses produced by the application of this technology create a display that generates superimposed images.

Treatment of diabetes focuses on two goals

Life is not over because you have diabetes. Make the most of what you have, be grateful. - Dale Evans

Diabetes01Diabetes is a chronic syndrome that is characterized by disordered metabolism and inappropriately high blood sugar. Diabetes is caused by inherited and/or acquired deficiency in production of insulin by the pancreas, or by the ineffectiveness of the insulin produced. Such a deficiency results in increased concentrations of glucose in the blood. The characteristic symptoms of diabetes are excessive urine production, excessive thirst and increased fluid intake and sometimes even blurred vision.

Type I or Juvenile diabetes is a type of diabetes that begins during childhood or adolescence. In this type of diabetes, the pancreas produces little or no insulin. Taking daily injections of insulin treats this condition. For this reason, this type of diabetes is also called insulin-dependent diabetes.

Breast Self-Examination is the primary method to discover the symptoms of breast cancer

Breast CancerCancer in general is a disease in which cells begin to grow rapidly and without of any control. Cancer cells can travel through the body by the way of blood or lymph nodes. When it comes to the specific case of Breast Cancer, every woman could be at risk for breast cancer. The risk of breast cancer varies with age, typically for women below the age of 25 this risk is about 1 in 20,000 whereas at the age of 45, it is 1 percent and at age 85, it is more than 1 in 10.

Researchers are yet to find out why and how normal cells suddenly can become cancerous. Thus, the fundamental cause or causes of such type of cancer is still unknown but scientists have found out that certain risk elements are associated to the development of breast cancer. These elements include family breast cancer history of occurring in mother or sister and early beginning of menstruation and also late menopause. In other cases women do not breast-feed or Women who have no children or have children late in life have more risk.

Prolonged use of certain drugs might also be a cause for amnesia

Driving is a spectacular form of amnesia. Everything is to be discovered, everything to be obliterated.” - Jean Baudrillard

Amnesia1 Amnesia is a disease related to memory. It can be loss of large block of interrelated memories or a block out of a particular portion of incidents. The people suffering from amnesia finds difficult in learning and understanding newer things in life. It is a great barrier to information sharing and badly affects an individual. This condition can be temporary but it might also lead to a long term syndrome. We are mostly familiar with it in a romantic portrayal of characters in movies and television. However in reality it is quite frightening. Amnesia can occur in both the genders and also at any age.

Hormone replacement therapy for women

“The risks of breast cancer, stroke, heart attack and blood clots outweigh the benefits for bones. And we have other drugs we can use to prevent osteoporosis.”-Dr. Jerry Avorn, associate professor of medicine at Harvard Medical School

HarmonesThere are several symptoms that signal the onset of menopause in women. Most women suffer from vaginal hot flashes, severe mood swings and itchiness or dryness. These irritating conditions are relieved by a treatment called hormone replacement therapy, also called hormone therapy for women. It has been a very popular and preferred treatment for uncomfortable menopausal symptoms. With natural menopause, the monthly cycles stop. The amount of hormones (progesterone and oestrogen) produced by the ovaries of a woman reduces significantly. Also, hormone replacement therapy is used in treating surgically menopausal women. The ovaries are removed by surgery for various reasons, hence the term ‘surgical menopause’.

Action of HRT

What hormone replacement therapy does is to provide the body with these hormones in order to reduce the postmenopausal symptoms that many women suffer from. There may be a slight risk in supplying just one of these two hormones. For example, for women with intact uterus, being given oestrogen might have a greater risk of endometric cancer. Of course, the amount of replacement hormones is less than what the ovaries normally produce in reproductive women. At a time, the replacement may not have many risks, but regular replacement of hormones might expose these women to slightly higher risk of strokes, cancer and fractures.

In a nutshell about HIV & AIDS, TB and Cancer

AIDS is our number one enemy. This enemy can be defeated. While the research for a cure continues, four principles — love, support, acceptance and care for those affected — can make us winners.” - Nelson Mandela

AidsTreatment for patients who are HIV & AIDS positive is a combination of 3 antiretroviral drugs which are referred to as ART or antiretroviral therapy. This combination is used to repress the HIV virus and stop the progress of the disease. With this latest therapy of treating HIV & AIDS patients, there has been a drop in the death rates and reduced suffering also. Of course this drug has to be taken very regularly and any break in treatment will create a massive set back. Children and pregnant women are also given ART treatment.

Though the drug is expensive there are many NGOs in third world countries, who take the responsibility of treating patients free of cost with funds raised from various sources. The WHO has been taking an active part in the research and treatment of this dreaded disease.
