Long-distance transport of nitrate requires xylem loading and unloading, a successive
process that determines nitrate distribution and subsequent assimilation efficiency. Here, we …

New data and a review of historiographic information from Neolithic sites of the Malaga and
Algarve coasts (southern Iberian Peninsula) and from the Maghreb (North Africa) reveal the …

SARS-CoV-2, the causative agent of COVID-19 1 , features a receptor-binding domain (RBD)
for binding to the host cell ACE2 protein 1 , 2 , 3 , 4 , 5 – 6 . Neutralizing antibodies that …

We report a case of a 63-year-old female patient who developed a recurrent urinary tract
infection (UTI) with extensively drug-resistant Klebsiella pneumoniae (ERKp). In the initial two …

At the time of the organization of the International conference on Use-Wear analysis 2012,

Multidrug-resistant (MDR) organisms have increased worldwide, posing a major challenge
for the clinical management of infection. Bacteriophage is expected as potential effective …

Background and Aims Roots typically respond to localized nitrate by enhancing lateral-root
growth. Polar auxin transport has important roles in lateral-root formation and growth; …

Nitrogen plays an important role in plant growth and development. Nitrate transporters have
been extensively studied in Arabidopsis, but in tomato they have not been functionally …

Eukaryotic cells are coated with an abundance of glycosylphosphatidylinositol anchor proteins
(GPI-APs) that play crucial roles in fertilization, neurogenesis, and immunity. The removal …
