Computer models of neuronal sound processing in brain lead to cochlear implant improvements

Intact hearing is a prerequisite for learning to speak. This is why children who are born deaf are fitted with so-called cochlear implants as early as possible. Cochlear implants consist of a speech processor and a transmitter coil worn behind the ear, together with the actual implant, an encapsulated microprocessor placed under the skin to directly stimulate the auditory nerve via an electrode with up to 22 contacts.

Researchers offer promise of strategy for curing HIV infection

Researchers have used radioimmunotherapy (RIT) to destroy remaining human immunodeficiency virus (HIV)-infected cells in the blood samples of patients treated with antiretroviral therapy, offering the promise of a strategy for curing HIV infection. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Research proves effectiveness of vaccine against leishmaniasis

The disease is considered endemic in the south states of Mexico. A research executed in the Autonomous University of Yucatan (UADY) has successfully proved, in test animals, the effectiveness of a vaccine that immunizes the organism against leishmaniasis, an ailment transmitted through insects very similar to mosquitos and mainly presents symptoms in the skin, liver or spleen.

New robot to guide surgery, needle insertion, catheters and stents

This robot has a hybrid powerstrain structure which will allow a precise, repetitive, planned and controlled insertion enhancing the current procedures used so far. In addition, it has a lower cost and it requires a brief period of learning.

Sca-1 stem cells replace steadily aging heart muscle cells

Up until a few years ago, the common school of thought held that the mammalian heart had very little regenerative capacity. However, scientists now know that heart muscle cells constantly regenerate, albeit at a very low rate. Researchers at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, have identified a stem cell population responsible for this regeneration.

Tel Aviv University researchers discover a protein that kills bacteria

In the arms race between bacteria and modern medicine, bacteria have gained an edge. In recent decades, bacterial resistance to antibiotics has developed faster than the production of new antibiotics, making bacterial infections increasingly difficult to treat. Scientists worry that a particularly virulent and deadly "superbug" could one day join the ranks of existing untreatable bacteria, causing a public health catastrophe comparable with the Black Death.

Scientists investigate factors that influence choice of abused drugs

Prescription opioid abuse has reached epidemic levels in the past 15 years. Scientists investigating why people favor one drug over another have found that oxycodone and hydrocodone are the drugs of choice for 75% of opioid-dependent individuals.

Severely neglected children more prone to indiscriminate friendliness

Children who experience profound neglect have been found to be more prone to a behavior known as "indiscriminate friendliness," characterized by an inappropriate willingness to approach adults, including strangers.

Researchers use hyperthermia to treat patients with malignant glioma

Malignant glioma is very sensitive to heat. Prof. Yunlong Ge and team from the Second Affiliated Hospital of Harbin Medical University, China used a brain tumor hyperthermia apparatus to treat malignant glioma patients, and achieved good therapeutic efficacy.

Researchers find evidence that gout clusters in families

It's historically known as 'the king of diseases and the disease of kings' and was long thought to be caused by an overindulgent lifestyle, but now scientists at The University of Nottingham have confirmed that 'gout' strongly runs in families.

IRCM researcher sheds light on inconsistencies between pharmacogenomic studies

A bioinformatics expert at the IRCM, Benjamin Haibe-Kains, recently published an article stressing the importance of standardizing drug screening studies in the prestigious scientific journal Nature. The study supports the need for further development and standardization to improve the reproducibility of drug screening studies, as they are important in identifying new therapeutic agents and their potential combinations with existing drugs.

Study: Unfolded protein response can increase risk of sudden cardiac death

A researcher at the Cardiovascular Institute (CVI) at Rhode Island, The Miriam and Newport hospitals has found a link to human heart failure that if blocked, may reduce the risk of sudden cardiac death.

Synaptic health in the brain closely linked to cognitive decline

Age-related cognitive decline and changes in the nervous system are closely linked, but up until recently, they were thought to result from the loss of neurons in areas such as the prefrontal cortex, the part of the brain important in working memory.

Experts explain how to prevent heartburn during holidays

Attracted by the decadent treats, fried meats, and festive cocktails of the Thanksgiving-to-New-Year feast, heartburn can be an unwelcome guest during the holidays. According to the American Society for Gastrointestinal Endoscopy, acid reflux affects about 30 million Americans.

New genetics promises to change faulty genes of future generations by using "designer sperm”

Bethesda, MD-Get ready: The "new genetics" promises to change faulty genes of future generations by introducing new, functioning genes using "designer sperm." A new research report appearing online in The FASEB Journal, shows that introducing new genetic material via a viral vector into the sperm of mice leads to the presence and activity of those genes in the resulting embryos.

ATN-224 inhibitor reduces tumor sizes in mouse model of lung adenocarcinoma

Many cancers have adapted to cope with high levels of immune system-produced free radicals, also referred to as reactive oxygen species, by overproducing antioxidant proteins. One of these proteins, superoxide dismutase 1, is overproduced in lung adenocarcinomas and has been implicated as a target for chemotherapy.
