Infertility Breakthrough With First Birth from Lab-matured Egg

...py for cancer may not have time to undergo ovarian stimulation so that their oocytes can be harvested and stored. Their only other option for preserving their fertility is the still-experimental option of having ovarian tissue removed before they undergo cancer therapy. The tissue is frozen and then transpla...

First Baby Born from Eggs Matured and Frozen in the Lab

...e, allowing more embryos to be created. "Ovarian stimulation is also time-consuming, taking between two and six weeks. Women who suffer sudden ovarian failure would not have time to wait for traditional methods, and so the new technique could therefore help them save and freeze several eggs before it is too la...

Embryo Protection Law in Germany

...ot having to go undergo repeated cycles of ovarian stimulation because enough eggs are being collected from the first cycle to freeze for use at a later date if the first cycle using the fresh eggs fails. This is much better for the health of the women. The increasing use of frozen eggs has also led to improve...

Parkinsons Disease Protein Pathway Identified

...mine. This lowering of dopamine leads to decreased stimulation of the brain's motor cortex. Although scientists have not known the exact cause of the loss of these dopamine-producing neurons, they believe it is related to dysfunctional mitochondria and oxidative stress. Mitochondria are the cell's "power plant...

Novel Treatment Beneficial for Colon and Liver Cancer

...ossible, according to the scientist, thanks to the stimulation of the immune system, since the introduction of the correct gene in the diseased body can cause it to repair itself and destroy the tumor. In addition, the researcher of the University of Navarra noted that colon cancer alone causes more than 500,0...

Gene Therapy for Parkinsons Disease

...s patients. And in the past decade, the deep brain stimulation has worked in as many as 70 percent of patients who have opted for the surgical procedure. If it doesn't work, the electrodes can be removed. Gene therapy could be a more natural way to treat the disease, said Dr. Feigin. This important study shows...

Sexual Fantasies Play an Important Role in Boosting Desire

... proper neurohormonal activity with a right sexual stimulation is necessary in order to experience sexual desire.... Carlos Sierra points out that education on sexual stimulation and response as well as healthy attitudes towards sexuality is extremely important. In this way, sex...

Hepatitis C Carries Another Risk-Cancer Of The Immune System

...rall risk is low. According to Giordano ,chronic stimulation of the immune system caused by hepatitis C might be contributing to the development of certain lymphomas. The study subjects recruited were 150,000 veterans from the Veteran Administration (Vietnam War). The scientists marked those with a diagnosi...

Potential Of Epilepsy Surgeries Are Not Fully Harnessed Say Brain Specialists

...afely. In this case, the options are: Deep-brain stimulation Major studies are beginning to see if implanting an electrode that emits a low-level electrical current could zap the bad brain tissue and stop seizures as they form. It is already used to control tremors in Parkinson's disease. Vagus nerve stimula...

Stimulating the Ankle Can Help Patients With Overactive Bladder

...ry Crawford Long Hospital urologist is using nerve stimulation in the ankle to better help control the bladder. "Known as percutaneous tibial nerve stimulation (PTNS), this is one of the least invasive forms of neurostimulation for urological conditions, such ...
