Drinking Decaf Coffee might increase Glucose Utilization in Brain

In a recent study published in the Nutritional Neuroscience, a group of researchers from Mount Sinai School of Medicine stated that brain energy metabolism associated with diabetes type 2 might improve by drinking decaffeinated coffee. Neurodegenerative disorders like the Alzheimer’s disease dementia and others are the diseases that can be triggered by the brain energy metabolism that is a dysfunction. Giulio Maria Pasinetti, who is a MD, PhD, and the leader of the team of scientists who investigated whether supplementing the diet with some standard decaffeinated coffee before the onset of diabetes would be able to improve the resistance to insulin and utilization of glucose in mice who had diet induced diabetes.

Stem Cell Stage bypassed by Scientist

Researchers at the Stanford University School of Medicine in California, converted cells from mouse skin into neural precursor cells, bypassing stem cell stage. Neural precursor cells are those cells that later develop into three main types of cells that are found in the brain and the nervous system. This report was published online in the early online January 30th issue of the Proceedings of the National Academy of Sciences. This study has questioned the old belief that the ability to become any other cell of the body, a characteristic of the stem cells called as pluripotency, is necessary in order to change from one cell type to another.

What You Should Know about Heart Attack – Symptoms and Treatment

A heart attack occurs when a coronary artery is clogged or blocked suddenly. Before the heart attack occurs, there may be a gradual blockage of a coronary vessel with cholesterol plaque. The difference between stable CAD and a heart attack is that during the heart attack, one of the cholesterol plaques has cracked, causing a hemorrhage that blocks the vessel, or the vessel has narrowed until a tiny clot or clump of platelets can block it and deprive the muscle downstream of the blood necessary for survival.

Sometimes, some of the cells that line the coronary artery are sheared off by a rapid blood flow or some other damaging process. The tissue that is exposed promotes vigorous clotting that can block the vessel suddenly. Sometimes blood flows into the exposed cholesterol plaque and shears off a portion of it, forming a flap valve that suddenly blocks the vessel. However the blockage occurs, it prevents blood from reaching some of the heart muscle, causing part of that muscle to die.

What are the symptoms of a heart attack ?
Classically, a heart attack presents with a sudden onset of severe, crushing chest pain located under the sternum (breast bone) and spreading to the left armpit, arm, shoulder, neck, and jaw. If pain is rated on a 1-10 scale, with 1 being very mild and 10 being the worst pain ever experienced, heart attack pain is often 8-10. At the beginning, the pain may be less severe and may come and go over a period of hours, but severe pain is common. The pain can be associated with nausea, vomiting, sweating, palpitations, and shortness of breath.
heart attack symptoms and pain
Sometimes people will have only abdominal discomfort or back pain. Women may have symptoms different from those in men. If a heart attack is suspected, you (or your family) should call an ambulance to take you to the nearest hospital. Speedy transport to the hospital is critical because 50% of all people who die of heart attack do so within the first hour. Many of these early deaths are preventable with prompt medical attention. The earlier treatment is given, the more heart muscle can be saved.

People with diabetes often have different or no symptoms of heart attack. Silent heart attacks are common. If you have several risk factors for heart disease, be alert for any heart attack symptoms, including sudden out-of-control blood glucose levels. It is not unusual for people with diabetes to have the symptoms of nausea and shortness of breath but no chest pain because of damage to the sensory nerves of the heart. Discuss with your doctor whether you need any tests. Heart attack is common in people with diabetes – 30-50% more common than in other people of similar age, sex, and risk factors. The risk of having another heart attack is increased, and the risk is higher for people with type 1 than for those with type 2 diabetes.

Adding Oxaliplatin boosts Chemotherapy for Colon Cancer

A new study on the drugs for colon cancer provides evidence for oxaliplatin to enhance the survival rates for the patients undergoing standard chemotherapy for advanced colon cancer. Earlier, a combination of 5-FU with Leucovorin was the choice of chemotherapy for colon cancer patients which showed 26 percent of deduction in death rates but currently it was studied that adding oxaliplatin to this combination could further rise the figures to another 23 percent.

Genes causing Mental illness

In one of the recent studies conducted by National Institutes of Health Science, it was revealed that genes implicated in schizophrenia and autism turns out to be the members of selected genes in which one can observe the peak in the regulatory activities during the environmentally-sensitive critical period. There is a mechanism which is popularly called as DNA methylation which actually switches on and off in the human’s brain prefrontal cortex. With the increase in the methylation, gene expression slows down after the birth. The scientists have found that the activity related to environmentally responsive regulatory across the lifespan really turns the genes off and on in the brain.

Brain scans help diagnose Dyslexia

Dyslexia also referred to as the disability to read and apprehend can now experience a major breakthrough in the field of research. Scientists in Chicago have found out some very interesting facts about the disorder and have come to the conclusion that the symptoms of the disorder in the child can be easily found and spotted in the much early days of his childhood. Now instead of waiting for the signs of the reading disorder and the disability can be found out much before a child even starts with the school.

Conventional autopsy or Virtopsy

In today’s television series and dramas you would come across scenes in which you can view video images and detailed scans of the victim’s body involved in a crime scene. These TV dramas basically promote virtopsy which as per autopsy and body imaging experts at The Johns Hopkins Hospital cannot replace the popular traditional autopsy. No doubt, full-body computed tomography (CT) scans, magnetic resonance imaging (MRI), ultrasound, X-ray and angiography are some of the great virtual imaging technologies however these are no match for the direct physical inspection of the body’s main organs.

Nurses rarely consult research evidences for routine practices

Routine practices are followed by the nurses in order to prevent the transmission and spreading of microbes that can cause infection in the hospital form the patient to the staff, from staff to the patient, from patient to patient and from patient to other visitors. These routine practices are taken to be the very foundations of the prevention and control of infection in the health care institution. These routine practises have different names in different countries and there is no universal name given to them. However, the routine practises should be applied to all the patients equally without any exceptions.

Levels of male hormones before birth allied with language delays in boys

New study reports that baby boys, who have higher exposure to male hormone- testosterone- before their birth are more prone to language delay risks in comparison with female babies. According to Professor Andrew Whitehouse, the lead author of the study at the University of Western Australia, 12 out of 100 infants- which are just estimated figures- show significant time lag in their speech development and though this ability of language development motleys from individual to other, male infants show slower rates of development than females. This study was published in the journal of Child Psychology and Psychiatry on 26th of this month.

Nurses at Hospitals to lose incentives

At Brighton and Sussex University Hospitals NHS Trust, almost 1,000 staff members are set to lose the recruitment and retention premium. Trust managers say this move will help the organization in saving around £0.5m a year. The unions have threatened to challenge this move. The payment was originally introduced at a time when the trust was experiencing a lot of difficulty with the recruitment process. Originally this payment was introduced as an incentive to registered nurses and allied health professionals. In 2006 when the recruitment problems eased the trust stopped offering the payment to the new recruits. The current statistics show that 46% of the registered nurses, midwives and nursery nurses still receive the payment.
