Diseases that dogs can detect

Scientists are investigating canines ’ extraordinary sense of smell, hoping that it will prove a more reliable predictor of illnesses than conventional testingLast week, researchers presented evidence that dogs could tell fromsniffing someone ’s socks whether they had malaria. After several months of training, a labrador and a labrador-retriever could tell if a child had the disease even if they were not showing symptoms.Continue reading...

This study shows that the magnitude of the host transcriptional response can differ markedly from related parasites with different virulence, and it enables a better understanding of the molecular interactions taking place between hosts and parasites.

Biomedica. 2020 May 01;40(Supl. 1):148-165 Authors: Ospina JD Abstract Los aptámeros son secuencias de ADN o ARN de cadena sencilla que adoptan la forma de estructuras tridimensionales únicas, lo cual les permite reconocer un blanco específico con gran afinidad. Sus usos potenciales abarcan, entre otros, el diagnóstico de enfermedades, el desarrollo de nuevos agentes terapéuticos, la detección de riesgos alimentarios, la producci&...

(Ehime University) An international collaborative team from PROS Ehime University and CellFee Science, Japan; the Walter and Eliza Hall Institute, Australia; Pasteur Institute, France; and Foundation for Innovative New Diagnostics, Switzerland developed a new diagnostic blood test which detects recent exposure to 'vivax' malaria. The new test can also identify people who may harbor dormant liver-stage malaria parasites, which can cause illness. This new diagnostic approach has the potential to enhance malaria surveillance and accelerate elimination.

Plasmodium falciparum is causative agent of human malaria. Sixty percent of mRNAs from its extremely AT-rich (81%) genome harbor long polyadenosine (polyA) runs within their ORFs, distinguishing the parasite from its hosts and other sequenced organisms. Recent studies indicate polyA runs cause ribosome stalling and frameshifting, triggering mRNA surveillance pathways and attenuating protein synthesis. Here, we show that theP. falciparum is an exception to this rule. We demonstrate that both endogenous genes and reporter sequences containing long polyA runs are efficiently and accurately translated inP. falciparum cells. We...
