Trees face the dilemma that achieving high plant productivity is accompanied by a risk of drought-induced hydraulic failure due to a trade-off in the trees' vascular system between hydraulic efficiency and safety. By investigating the xylem anatomy of branches and coarse roots, and measuring branch axial hydraulic conductivity and vulnerability to cavitation in 4-year-old field-grown aspen plan...

The garden pea (Pisum sativum L.), like most members of Fabaceae family, is capable forming symbioses with beneficial soil microorganisms such as nodule bacteria (rhizobia), arbuscular mycorrhizal (AM) fungi and plant growth promoting (PGPB). autoregulation nodulation (AON) system known to play an important role in controlling both the number nodules level root colonization by AM via root-to-sh...

Physiological uniformity and genetic effects on canopy-level gas-exchange and hydraulic function could impact loblolly pine (Pinus taeda L.) plantation sustainability and ecosystem dynamics under projected changes in climate. Over a 1-year period, we examined genetic effects on mean and maximum mid-day canopy conductance (Gs, Gsmax) and transpiration (E, max-E) within a juvenile loblolly pine p...

TOPIC: Chest Infections TYPE: Medical Student/Resident Case Reports INTRODUCTION: Histoplasmosis and Tuberculosis are two disease entities which may have similar presentations in the immunocompromised patient. Here we present a case of disseminated histoplasmosis patient with advanced HIV. CASE PRESENTATION: A 60-year-old male no known past medical history who presented fatigue, anorexia, dizzi...

To obtain an exact solution of a four-body system containing two quarks and two antiquarks interacting through two-body terms is a cumbersome task that has been tackled with more or less success during the last decades. We present an exact method for the study of four-quark systems based on the hyperspherical harmonics formalism that allows us to solve it without resorting to further approximat...
