Parkinson's disease

Parkinson's Patients To Voluntarily Control Brain Wave Activity

Parkinson’s disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. As the disease worsens, non-motor symptoms become increasingly common. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. Thinking and behavioral problems may also occur. Dementia becomes common in the advanced stages of the disease. Depression and anxiety…

Novel MRI Sensor Can Peer Deep Into The Brain

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain. MIT researchers have now devised a new way to image calcium activity that…

Hip Replacements

6 Out Of 10 Hip Replacements Last 25 Years

How long will a total hip replacement last? A large study on total hip replacement (THR) has shown that six out of ten of these prosthetic devices continue to function well after 25 years. Eight out of ten knee replacements also last that long, according to the same study. “This is much longer than belief.”…

Misuse Of Prescribed Opioids

Prevalence And Risk Factors For Misuse Of Prescribed Opioids

Opioids are substances that act on opioid receptors to produce morphine-like effects. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea; replacement therapy for opioid use disorder, reversing opioid overdose; suppressing cough, suppressing opioid-induced constipation; as well as for executions in the United States. Opioids bind to and activate opioid receptors on cells located in many areas of the brain,…

Rheumatoid

Molecular Defect Underlying Rheumatoid Arthritis

In rheumatoid arthritis, immune cells called helper T cells behave differently from their counterparts in healthy cells and in other autoimmune diseases. Stanford scientists have learned why. Stanford University School of Medicine investigators succeeded in countering inflammation and tissue damage caused by rheumatoid arthritis in mice engrafted with human joint-lining tissue and a human immune system. The researchers…

The immune system is the body’s best defense in fighting diseases like HIV and cancer. Now; an international team of researchers is harnessing the immune system to reveal new clues that may help in efforts to produce an HIV vaccine. SFU professor Mark Brockman and co-authors from the University of KwaZulu-Natal in South Africa have…

Sleeping Sickness

Fexinidazole The First All-Oral Treatment For Sleeping Sickness

Marketing authorization of fexinidazole for the treatment of Trypanosoma brucei gambiense human African trypanosomiasis (HAT), more commonly known as sleeping sickness; has been granted in the Democratic Republic of Congo (DRC). This approval paves the way for the distribution of fexinidazole in endemic countries this year; with another submission planned in Uganda. Sleeping sickness is usually fatal…

Enlarged prostate

Enlarged Prostate Could Actually Stopping Tumor Growth

For men older than about 60, an enlarged prostate means feeling the urge to make a pit stop way too often throughout the day. But a new study shows that if these men also happen to have prostate cancer; the larger prostate actually impedes tumor growth. The findings suggest that it might be a bad idea…

Human Kidneys

One Step Closer To Growing Made-To-Order Human Kidneys

In a study with significant implications for human organ transplantation, researchers have successfully grown functional mouse kidneys inside rats from just a few donor stem cells. The results of the study, led by researchers from the National Institute for Physiological Sciences in Japan; will publish in an upcoming issue of Nature Communications. For patients with end-stage…
