Open-tubular capillary electrochromatography (OT-CEC) is an alternative approach to conventional CEC. The primary advantage of OT-CEC is the elimination of problems associated with frits and silica particles in conventional CEC. This report is an investigation of the utility of using a polymeric surfactant (molecular micelle) for OT-CEC. In this approach, fused-silica capillaries coated with th...

OBJECTIVE Lifelong functional, adaptive, and economic outcomes of moderate to severe infantile malnutrition are not well known. We assessed social status and income at midlife in a cohort of Barbadian adults, hospitalized for protein-energy malnutrition (PEM) during the first year of life, with good nutrition and health thereafter, in the context of a 40-year longitudinal case-control study. We...

This document specifies how the services of MIME and PEM can be used in a complementary fashion. MIME, an acronym for "Multipurpose Internet Mail Extensions", defines the format of the contents of Internet mail messages and provides for multi-part textual and non-textual message bodies. PEM, an acronym for "Privacy Enhanced Mail", provides message authentication/integrity and message encryption...

Using data from extensive vibrational tests of the new aircraft Saab 2000 a combined method for vibration analysis is studied. The method is based on a realization algorithm followed by standard prediction error methods (PEM). We nd that the realization algorithm gives good initial model parameter estimates that can be further improved by the use of PEM. We use the method to get insights into t...

OBJECTIVE Currently, pediatric emergency medicine (PEM) physicians have limited data on point-of-care echocardiography (POCE). Our goals were to (1) determine the overall accuracy of POCE by PEMs in assessing left ventricular (LV) systolic function visually, presence or absence of pericardial effusion, and cardiac preload by estimating inferior vena cava (IVC) collapsibility, in acutely ill chi...

The integration of orthopedic implants with host bone presents a major challenge in joint arthroplasty, spinal fusion and tumor reconstruction. The cellular microenvironment can be programmed via implant surface functionalization allowing direct modulation of osteoblast adhesion, proliferation, and differentiation at the implant--bone interface. The development of layer-by-layer assembled polye...

ABSTRACF We report cell numbers within major subsets oflymphocytes in the spleen, mesenteric nodes, and recirculating pool ofweanling mice subjected to protein-energy malnutrition (PEM). PEM and thymus (T)-dependent immunodepression were induced in male C57BL/6J mice by a low-protein (LP) diet fed ad libitum. Recirculating lymphocyte numbers were estimated by enumerating labeled and unlabeled c...

We have studied ion and electron irradiation of self-assembled monolayers (SAMs) of 2-(4'-methyl-biphenyl-4yl)-ethanethiol (BP2, CH3-C6H4C6H4CH2CH2-SH), phenyl mercaptan (PEM, C6H5CH2CH2-SH), and 4'-methyl-biphenyl-4-thiol (BP0, CH3-C6H4C6H4-SH) deposited on Au(111) substrates. Desorption of neutral particles from PEM/Au and BP2/Au was investigated using laser ionization in combination with mas...
