Scratch no more: Gene for itch sensation discovered

...can be used to suppress the itch sensation without affecting the pain sensation, according to Chen. And because pain can be an important protective cue that warns of danger, it may be a distinct advantage to have an anti-itch medication that doesn't compromise our pain-sensing capability. GRPR had been fairly...

Identified main genetic variants involved in response to HIV

...eotide polymorphisms (SNPs), are single variations affecting only one nucleotide or base of the genomic sequence. Despite humans sharing 99.9% of the genome sequence, there are still 3 million genetic variations –which make us different from one another– 90% of which are due to SNPs. Hence, a good knowledge of...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes
