Researchers detail a computational model that explores how the auditory system tackles this complex task. They examined how the brain achieves a word by using animal calls as a greatly simplified model system. They fed their algorithm a bank of marmoset calls and asked it to find the most informative and consistently recognizable features. So, by detecting the presence or absence of these most informative features in incoming sounds, the model can identify the vocalization type with very high accuracy.
Scientists reported their first success at engineering scaffolds that replicate the physical characteristics of osteochondral tissue - basically, the hard bone beneath a compressible layer of cartilage that appears as the smooth surface on the ends of long bones.
The discovery of tuft cells (in green) in mice lungs after flu gives researchers insights into how a bad respiratory infection may set the stage for certain inflammatory conditions, such as asthma. The cells are named for the elongated microvilli which project from their surface.
New rules on training, hospital locations, and video health consultations are some of the key proposals put forward in a new healthcare law announced by the French health minister. Ms Buzyn announced five key reforms, including more information on data collection and online consultations.
Surgeons in Baltimore have performed the world's first kidney transplant in which both the living donor and the recipient are HIV-positive. The success of the operation could potentially make organs more widely available to patients infected with the AIDS virus.
According to a study published in American Journal of Cardiology 3 percent of heart attack were readmitted within 30-days, 13% were readmitted within a year and 8% died due to cardiac causes. They added that this was seen in patients with low care scores that put them at a higher risk of recurrence.
Aneurysms form as abnormal bulges over an artery, and, if ruptured, can lead to serious health complications or even death. Some can exist for a long time without rupturing, and surgery can be risky, so a parameter to help surgeons is needed. Researchers report that they have developed a simple nondimensional parameter that depends on both geometry and flow waveform to classify the flow mode in both sidewall and bifurcation aneurysms.
The frontline combination of fulvestrant (Faslodex) and anastrozole resulted in a sustained benefit in progression-free survival (PFS) and a significant improvement in overall survival (OS) compared with anastrozole alone in patients with postmenopausal, hormone receptor (HR)–positive metastatic breast cancer, according to long-term results of the SWOG S0226 trial.
A current research suggests that artificial intelligence in healthcare could expand at a growth rate of 43.5 percent from 2018 to reach $27.6 billion by 2025. Furthermore a previous survey suggested that Ninety-one percent of 500 healthcare leaders showed confidence that they will see a rapid increase in AI in near future.
Results of a registry study suggest that Testosterone replacement therapy is helpful in preventing progression to Diabetes. This could be useful in men with low testosterone, hyopogonadism and prediabetes. The researchers added that the aim should be to achieve normoglycemia rather than a prediabeteic state.
