The POM-1 metallo-β-lactamase is a subclass B3 resident enzyme produced by Pseudomonas otitidis, a pathogen causing otic infections. The enzyme was overproduced in Escherichia coli BL21(DE3), purified by chromatography, and subjected to structural and functional analysis. The purified POM-1 is a tetrameric enzyme of broad substrate specificity with higher catalytic activities with penicillins a...

POM is a Parallel Observable Machine featuring mechanisms for building and observing distributed applications. It comes in the form of a library built upon the many communication kernels available on current parallel architectures and a loader that provides the user with a homogeneous syntax for launching parallel applications on any parallel platform. The prior goal of POM is not to o er numer...

OBJECTIVE Despite the many complications of succinylcholine, it is still widely used as a superior muscle relaxant for rapid sequence induction. One of these complications is postoperative myalgia (POM). The aim of this study was to investigate the prophylactic effect of low-dose ketamine on the incidence and severity of POM. MATERIALS AND METHODS In this double-blind clinical study, a total ...

Primary somatosensory cortex (S1) receives two distinct classes of thalamocortical input via the lemniscal and paralemniscal pathways, the former via ventral posterior medial nucleus (VPM), and the latter, from the posterior medial nucleus (POm). These projections have been described as parallel thalamocortical pathways. Although the VPM thalamocortical projection has been studied in depth, sev...

PURPOSE The purpose of this study was to investigate appropriate contrast reference values (CRVs) by comparing the contrast in phantom and clinical images. MATERIALS AND METHODS Phantom contrast was measured using two methods: (1) counting the number of visible pits of different depths in an aluminum plate, and (2) obtaining the contrast-to-noise ratio (CNR) for 5 tissue-equivalent materials ...

Central testosterone aromatization is required for the activation of both appetitive (ASB) and consummatory (CSB) male sexual behavior in Japanese quail. There are two major clusters of aromatase immunoreactive (ARO-ir) cells in the rostral forebrain; these outline the nucleus preopticus medialis (POM) and the nucleus striae terminalis (BST). We investigated the role of these nuclei in the regu...

The synthetic engineering of anionic polyoxometalate (POM) clusters with predefined properties tailored to specific applications is a great challenge using routine "one-pot" POM syntheses. Under such conditions, difficulties often arise from the multitude of complex reaction pathways and self-assembly processes occurring in solution. In this respect the major role of the charge balancing cation...

The Product Oriented Manufacturing (POM) concept here presented addresses competition in today’s changing global market of manufacturing companies. It is a challenge to the Function Oriented Manufacturing (FOM) concept supposedly adequate for dealing with demand changes and large product variety without needing reconfiguration. The POM concept evolves from the traditional cellular manufacturing...

Using pulsed gradient spin-echo NMR, we studied molecular self-diffusion in aligned samples of a hybrid lyotropic lamellar L(alpha) phase. This composite organic-inorganic material was obtained by doping the lamellar phase of the nonionic surfactant Brij-30 with the [PW(12)O(40)](3-) polyoxometalate (POM). Both water and POM self-diffusion display a large anisotropy, as diffusion is severely re...

Sinking particulate organic matter (POM, phytodetritus) is the principal limiting resource for deep-sea life. However, little is known about spatial variation in POM supply to the abyssal seafloor, which is frequently assumed to be homogenous. In reality, the abyss has a highly complex landscape with millions of hills and mountains. Here, we show a significant increase in seabed POM % cover (by...
