The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Vasopressin in the brain maintains size of vasopressin neurons even when body fluid becomes more diluted

The anti-diuretic hormone "vasopressin" is released from the brain, and known to work in the kidney, suppressing the diuresis.

Study evaluates Masimo SpHb's accuracy in monitoring low hemoglobin levels

Masimo announced today that a new study demonstrating the clinical accuracy and value of its noninvasive and continuous hemoglobin monitoring technology breakthrough was presented this week at the Society of Critical Care Medicine Annual Critical Care Congress in San Diego.

Researchers examine brain's role in breathing

Much of our knowledge of the brain's role in regulating breathing comes from research with mice and rats. A chemical receptor within the brain stem communicates with the central nervous system to generate the basic pattern of breathing. The next step is applying that information to human tissue to identify these critical components in the human brain and their medical implications.

Major breakthrough: Genome-based medicine for treatment of alcoholism

For the first time in alcohol addiction research, UVA investigators have successfully treated alcohol-dependent individuals with medication that is tailored specifically to match their genetic profile.

Researchers believe driver mutations promote development, growth of prostate cancer

Prostate cancer is known to occur typically in older men. Yet some patients are younger than 50 years at the time of diagnosis. Scientists assume that these cases might be the key to understanding the biology of this disease. Early prostate cancer might be a subtype which is characterized by a relatively small number of genetic modifications.

Scientists find ADAR1 enzyme protect against measles virus

Scientists at The Scripps Research Institute have found that a known enzyme in cells protects against measles virus, likely by altering the virus's genetic material, RNA. Cells lacking the enzyme become highly vulnerable to the virus's destructive effects. The enzyme also protects against several other respiratory viruses, including influenza A.

New research suggests humans use senses to keep track of time

Humans use their senses to help keep track of short intervals of time according to new research, which suggests that our perception of time is not maintained by an internal body clock alone.

Cognition Therapeutics closes $2.5 million Series A1 financing

Cognition Therapeutics Inc., a drug discovery company developing novel, small molecule disease-modifying treatments for Alzheimer's, has closed on a $2.5 million Series A1 financing it will use to bring one or more of its compounds to Investigational New Drug (IND) candidate status. The round was led by Golden Seeds, one of the nation's largest angel investing groups, and was syndicated with Tech Coast Angels.

ACD CPR performed with combination of ResQPump and ResQPOD could save lives of cardiac arrest patients

A combination of two devices could save the lives of thousands of cardiac arrest patients each year if implemented nationwide, suggests clinical trial results published in today's online edition of The Lancet.

Damaged alpha-synuclein proteins can spread in a 'prion-like' manner: Study

The study, published in the Journal of Clinical Investigation, reveals that damaged alpha-synuclein proteins can spread in a 'prion-like' manner, an infection model previously described for diseases such as BSE.

HIV-infected patients three times more likely to suffer strokes

While the overall hospitalization rate for stroke has declined in recent years, the numbers have jumped dramatically for patients infected with human immunodeficiency virus (HIV), suggesting they may be up to three times more likely to suffer a stroke than people uninfected by the virus that causes AIDS.

Prevention of awareness during anesthesia

Out of every 1000 patients, two at most wake up during their operation. Unintended awareness in the patient is thus classified as an occasional complication of anesthesia—but being aware of things happening during the operation, and being able to recall them later, can leave a patient with long-term psychological trauma.

No robust conclusions possible on advantages or disadvantages of PET

Malignant gliomas are fast-growing brain tumours with poor prospects of recovery depending on disease stage. Experts hope that the examination of patients by means of positron emission tomography (PET) is more helpful in the choice of the right treatment than other procedures. In a final report the German Institute for Quality and Efficiency in Health Care (IQWiG) has now investigated the benefit of PET in the detection of recurrences. According to this report, no robust conclusions are possible on the advantages or disadvantages of PET.

Brains of migraine sufferers show higher proportion of lesions of brain microvessels

Recent work, in particular the CAMERA study, has used MRI to study the brains of migraine sufferers and has shown that a higher proportion of these patients exhibit lesions of the brain microvessels than the rest of the population.

Anaesthetising an arm affects brain activity and rapidly impairs body perception

An Inserm research team in Toulouse, led by Dr Stein Silva (Inserm Unit 825 "Brain imaging and neurological handicaps"), working with the "Modelling tissue and nociceptive stress" Host Team (MATN IFR 150), were interested in studying the illusions described by many patients under regional anaesthetic.

Pervasis pursues matrix-embedded endothelial cell-based therapy to target and regulate cell stroma

Pervasis Therapeutics, Inc. today announced that the company is pursuing a matrix-embedded endothelial cell-based therapy (PVS-30200) to target and regulate cell stroma (the tumor environment or "ecosystem" that is comprised of various supporting cell types distinct from cancer cells) in order to prevent key processes that play a role in advancing solid tumor growth and metastasis.

Delaying onset of Alzheimer's disease by 10 years could potentially eliminate the disease completely

The combined results of a genetic blood test and a five-minute functional MRI successfully classified more than three-quarters of healthy older adults, many of whom were destined to develop cognitive decline within 18 months of testing.

New research: HIV individuals are more likely to have stroke

New research suggests that people infected with human immunodeficiency virus may be up to three times more likely to have a stroke compared to those not affected with HIV. The study is published in the January 19, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.

Writing by hand strengthens learning process, while keyboard typing impairs

When writing by hand, our brain receives feedback from our motor actions, together with the sensation of touching a pencil and paper. These kinds of feedback is significantly different from those we receive when touching and typing on a keyboard.
