A recent article in the British newspaper, Daily Mirror discussed a medical study that attempted to prove there was a link between pregnant women’s sleeping positions and stillbirth. The author is of the opinion that the study was small and biased and therefore “there is a serious need for more research before we’re in a strong position to make ¬any recommendations.” Obviously this author has limited knowledge about the cardiovascular system of a pregnant woman. Our organs and tissues require oxygen to function. Without it, they essentially die. Blood from the lower part of our body flows back to the heart where it receives oxygen, compliments of a large blood vessel called the Inferior Vena Cava (IVC). The i...

Frontal lobe activation during object permanence: data from near-infrared spectroscopy. The ability to create and hold a mental schema of an object is one of the milestones in cognitive development. Developmental scientists have named the behavioral manifestation of this competence object permanence. Convergent evidence indicates that frontal lobe maturation plays a critical role in the display of object permanence, but methodological and ethical constrains have made it difficult to collect neurophysiological evidence from awake, behaving infants. Near-infrared spectroscopy provides a noninvasive assessment of changes in oxy- and deoxyhemoglobin and tot...

I might complain, but I should also be flattered that I am as busy as I am. Mama is in demand, little muffin. Still, things are beginning to slow down to a tolerable level on my end, which means I will be back to blogging. Today I was working on some writing when I had cause to review some historical texts. It gives me pause to stop and consider things that we take for granted. For example, think about how blood flows through the heart and lungs… Figure 1: Blood flows from right to left, across the lungs. I can’t tell you how many times a day I look at a heart and  take for granted that blood should flow from the venous circulation, into the right side of the heart, acros...

Was my body warning me I was having a heart attack, or were these just the aftermath of a morning spent toiling with a shovel? Now that I’m of an AARP age, it’s a question I shouldn’t ignore. Snow shoveling is a known trigger for heart attacks. Emergency rooms in the snowbelt gear up for extra cases when enough of the white stuff has fallen to force folks out of their homes armed with shovels or snow blowers.  What’s the connection? Many people who shovel snow rarely exercise. Picking up a shovel and moving hundreds of pounds of snow, particularly after doing nothing physical for several months, can put a big strain on the heart. ...

That dropped stroke from the third leading cause of death in the United States to the fourth. Good news? Yes and no. It’s always good news when fewer people die. The reduction suggests a payoff for efforts to prevent stroke and improve the way doctors treat it. Yet the drop from third to fourth place is due largely to an accounting change. The CDC reorganized another category, “chronic lower respiratory diseases” (mainly chronic bronchitis and emphysema), to include complications of these diseases such as pneumonia. The change substantially increased the number of deaths in this c...

Anamika Veeramani, from Cleveland, Ohio, won the Scripps National Spelling Bee this weekend by spelling “stromuhr,” a rheometer designed to measure the amount and speed of blood flow through an artery. Don’t feel bad — we’d never heard of it before either, and we’re supposed to be experts in this stuff.

I’m talking about chocolate! Yes sir, dark gold, pure happiness! You’ve probably heard the buzz about dark chocolate, and how it’s good for your blood pressure, lowers cholesterol, prevents cancer and can fix nearly anything that is wrong with you, except that expanding waistline. (And for the record — white chocolate is not really chocolate at all. It’s milk solids and fat. No cocoa. Nada.) The basic ingredients of dark chocolate include cacao beans, sugar, soy lecithin (an emulsifier to preserve texture), and flavorings. This yummy treat, which contains fewer milk solids than its more popular cousin, milk chocolate, often is rated by the percentage of cocoa solids in the bar. The ...

A person, wearing a special helmet which measures the brain’s electrical activity (EEG) and changes in cerebral blood flow (NIRS), thinks of a particular movement. The collected data from the sensors is then transferred over to a central unit which enables statistical processing of the complex information from these two types of sensors. As a result, Honda’s ASIMO humanoid robot ma...

The measuring of the blood flow can determine where stents need to be implanted. Studies have shown that this new method is more effective than X-Ray examinations.

With a full 740 milliliters of blood circulating in the brain each minute, and even more during sleep … you see its significance.Brain specialists tell us that when the brain’s blood flow is slowed or blocked people are in serious trouble. In fact blood flow can be a clue to dementia. We’ve all learned more recently through mind-bending stories such as anchor Bob Woodruff’s recovery from brain damage suffered in Iraq. Sadly, ABC News reported yesterday that 1.4 million additional Americans suffer from traumatic brain injuries. Luckily,  medical miracles recently related to blood flow … promise incredible results that benefit all of u...

I really do hope that this is a success. The pump is implanted into the patient’s body and pumps blood from the weakened left ventricle to the rest of the body at the same rate as a healthy heart. In addition to helping 75 percent of patients stay alive for at least six months, or until a donor heart becomes available, the device assists patients’ original hearts regain function, thereby allowing other organs to heal by restoring blood flow. The device is about the size of a “D” sized battery which will allow it to help patients both big and small and male and female.

Diddley is famous for ever-cool tunes such as "Who Do You Love" and "I'm a Man." Well, at least he was in the right location: Diddley was actually at the hospital for a checkup when the heart attack struck. This ensured he got prompt care that may very well have saved his life. It appears Diddley suffered the heart attack on Friday of last week, but it was only announced today. This afternoon a spokeswoman stated that the now-elderly guitar hero felt unwell during his Friday checkup and was transferred to the emergency room, which is where the heart attack occurred. Diddley had surgery soon after to have a stent fitted. This will improv...

An infrared therapy is showing promising results for the reduction of pain from peripheral neuropathy. Anodyne Infrared Therapy is a treatment that uses light energy to exponentially increase (up to 400%) the circulation in peripheral areas (arms, legs). Light-emitting diodes are fitted into flexible pads that can be applied directly to the skin on any affected part of the body. The light energy helps increase blood flow by delivering nutrients to the injured site. Anodyne therapy consists of 10 to 12 sessions ...
