Since 1995, LEP has steadily increased the center of mass energy of the colliding beams, from the M Z resonance to 133, 161 and 172 GeV. New measurements of the strong coupling constant, α s , at these energies have been performed by the LEP experiments, L3, ALEPH, OPAL and DELPHI. In this article, the new results are summarized, and combined with the previous LEP measurement of α s (M Z) in or...

The mechanisms of targeting and insertion of chloroplast-encoded thylakoid membrane proteins are poorly understood. In this study, we have used a translation system isolated from chloroplasts to begin to investigate these mechanisms. The bacterial membrane protein leader peptidase (Lep) was used as a model protein because its targeting and insertion mechanisms are well understood for Escherichi...

Pain is a highly subjective experience, and the availability of an objective assessment of pain perception would be of great importance for both basic and clinical applications. The objective of the present study is to develop a novel approach to extract pain-related features from single-trial laser-evoked potentials (LEPs) for classification of pain perception. The single-trial LEP feature ext...

OBJECTIVE Obesity is a complex heterogeneous disease that is caused by genes, environmental factors, and the interaction between the two. The leptin (LEP) and leptin receptor (LEPR) genes have been evaluated for polymorphisms that could potentially be related to the pathophysiology of obesity and its complications. The aim of this study was to investigate the role of LEP G2548A and LEPR 668A/G ...

Twenty-one million Americans are limited in English proficiency (LEP), but little is known about the effect of medical interpreter services on health care quality. Asystematic literature review was conducted on the impact of interpreter services on quality of care. Five database searches yielded 2,640 citations and a final database of 36 articles, after applying exclusion criteria. Multiple stu...

This paper uses school-level data available from the Schools and Staffing Survey and the California Department of Education to assess the extent to which African Americans versus non-Hispanic whites attend schools with children with Limited English Proficiency (LEP). When examined at the national level, LEP students do not “crowd” the schools attended by most African American and non-Hispanic w...

Plant-based fermentations provide an untapped source for novel biotechnological applications. In this study, a probiotic named Lactobacillus fermentum 21828 was introduced to ferment Lentinus edodes. Polysaccharides were extracted from fermented and non-fermented L. edodes purified via DEAE-52 Sephadex G-100. The components designated F-LEP-2a NF-LEP-2a analyzed by FT-IR, H...

BACKGROUND Leptin (Lep) is known for its involvement in the regulation of reproductive functions. It is important for uterine receptivity, implantation, placental growth and maternal energy homeostasis in several species, but Lep's function in the pregnant dog has not been investigated. METHODS Pregnant bitches were ovariohysterectomized at pre-implantation, post-implantation, mid-gestation a...
