BACKGROUND Although the Pneumonia Severity Index (PSI) has been extensively validated, little is known of the impact of its routine use as an aid to site-of-treatment decisions for patients with pneumonia who present to emergency departments (EDs). METHODS A prospective, observational, controlled cohort study of patients with pneumonia was conducted in 8 EDs that used the PSI (PSI-user EDs) a...

PII: S0962-8924(99)01711-0 [PSI] was originally described in 1965 by Cox as a translation infidelity factor (Fig. 1)1. In [PSI] strains, a weak suppressor tRNA produced detectable nonsense suppression (stop-codon readthrough; see Box 1), whereas in [psi] strains the same tRNA suppressor appeared to be inactive1,2. Later experiments revealed that [PSI] was not required for suppressor tRNA functi...

let $g$ be a finite group‎. ‎we denote by $psi(g)$ the integer $sum_{gin g}o(g)$‎, ‎where $o(g)$ denotes the order of $g in g$‎. ‎here we show that‎ ‎$psi(a_5)< psi(g)$ for every non-simple group $g$ of order $60$‎, ‎where $a_5$ is the alternating group of degree $5$‎. ‎also we prove that $psi(psl(2,7))

Oxygenic photosynthesis supports virtually all life forms on earth. Light energy is converted by two photosystems-photosystem I (PSI) and photosystem II (PSII). Globally, nearly 50% of photosynthesis takes place in the Ocean, where single cell cyanobacteria and algae reside together with their viruses. An operon encoding PSI was identified in cyanobacterial marine viruses. We generated a PSI th...

Water deficits during seed filling often decrease seed size in soybean (Glycine max L.). The physiological basis for this response is not known but may result from direct effects of low seed water potential (Psi(w)) on the seed filling process. To determine whether low Psi(w) occurred in reproductive tissues of soybean, we monitored the water status (Psi(w), Psi(s), and Psi(p)) of leaf, pericar...
