Abstract:

A biomonitoring program has been developed in support of the National Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants. The program focuses on the use of laboratory toxicity tests on aquatic plants and animals to predict ecosystem impact caused by toxic pollutants. Both acute and chronic toxicity tests were developed to test effluents and ambient waters. Laboratory and biological field studies were conducted at nine sites. Single species laboratory toxicity tests were found to be good predictors of impacts on the ecosystem when two or more species were

Dramatic progress has been made in the last several years in our understanding of the properties of neutrinos with evidence for neutrino flavor transformation coming from measurements of atmospheric neutrinos by SuperKamiokande, of solar neutrinos by the Sudbury Neutrino Observatory (SNO), and of reactor neutrinos by KamLAND. These results are a step in the ongoing program of science that is carried out in underground laboratories. The potential for additional significant discoveries with new capabilities in underground laboratories exists and should be exploited. Discoveries are likely to be

Abstract:

There is virtually universal consensus that the health care system in the United States is too expensive and that costs need to be limited. Similar to health care costs in general, clinical laboratory expenditures have increased rapidly as a result of increased utilization and inflationary trends within the national economy. Economic constraints require that a compromise be reached between individual welfare and limited societal resources. Public pressure and changing health care needs have precipitated both subtle and radical laboratory changes to more effectively use allocated resources. Res

ABSTRACT In 1996 and 1997, 68 hospital laboratories throughout the United States determined the β-lactamase production and susceptibility to macrolides of 1,998 isolates of Haemophilus influenzaeobtained from patients with community-acquired respiratory tract infections. The MICs at which 90% of the isolates are inhibited of azithromycin, erythromycin, and clarithromycin were 4, 8, and 16 μg/ml, respectively. By National Committee for Clinical Laboratory Standards interpretive criteria, 99 and 78% of the isolates were susceptible to azithromycin and clarithromycin, respectively. The prevalence

Abstract:

Clostridioides difficile infection (CDI) disproportionately affects certain populations, but few studies have investigated health outcome disparities among patients with CDI. This study aimed to characterize CDI treatment and health outcomes among patients by age group, sex, race, and ethnicity. This was a nationally representative, retrospective cohort study of patients with laboratory-confirmed CDI within the Premier Healthcare Database from January 2018 to March 2021. CDI therapies received and health outcomes were compared between patients by age group, sex, race, and Hispanic ethnicity us

Abstract:

In the past two decades, runoff-permeable porous pavement and porous friction courses of pavement systems have been implemented more frequently, first in Europe and subsequently in the United States. Consequently, research and case studies are increasing, with a commensurate increase in the knowledge base for these drainable pavement matrices and systems. The main distinguishing parameter of these porous matrices is the hydraulic conductivity (k), as compared with traditional impervious pavements. Equipment and standards for measuring k vary widely. This variability includes laboratory and fie

Abstract:

U.S. offshore wind energy resources are abundant, indigenous, and broadly dispersed among the most expensive and highly constrained electricity load centers. Economic capacity expansion models developed at the National Renewable Energy Laboratory show that offshore wind energy can compete in future U.S. electric energy markets without major changes in the market variables or revolutionary technological breakthroughs. However, significant research, development, and deployment will be needed to bring the current technology through a course of cost reductions. To maximize the resource potential,

On June 10, 2019, three members of a Congolese family with EVD-like symptoms traveled to western Uganda’s Kasese District to seek medical care. Shortly thereafter, the Viral Hemorrhagic Fever Surveillance and Laboratory Program (VHF program) at the Uganda Virus Research Institute (UVRI) confirmed that all three patients had EVD.

Abstract:

Critical results demand rapid patient evaluation, possibly followed by life-saving intervention. A national survey of children's hospitals determined the critical limits used for emergency notification of critical laboratory results. Mean low and high critical limits for children for the tests listed most frequently were as follows (millimoles per liter): glucose, 2.6 and 24.7; potassium, 2.8 and 6.4; calcium, 1.62 and 3.17; and sodium, 121 and 156. For newborns, significantly different (P &lt; .01) critical limits were glucose, 1.8 and 18.2; and potassium, 7.8. Hematology mean critical li

Abstract:

The assessment of backwater resulting from extra energy losses on flood flows caused by bridge constrictions is of vital interest in hydraulic engineering due to its importance in the design of waterways and management of flooding. Although many detailed methods for estimating bridge backwater have been developed, an initial estimate of the magnitude of bridge backwater using a practical model, such as the multiple linear regression (MLR) technique, has a crucial importance for rapid evaluation of flood damages upstream of the bridge structure.

Abstract Abstract 2203 Background: Thrombotic thrombocytopenic purpura (TTP) is frequently characterized by severe ADAMTS13 deficiency, the cause of which is unknown. An important exception is ticlopidine-associated TTP (tc-TTP), the most common drug-induced TTP syndrome. In 1998, a possible association of TTP with ticlopidine was reported. In 1999, two additional series reported this association. In 2000, a fourth study reported severe A DAMTS13 deficiency among six of seven tc-TTP persons- suggesting a causal pathway. All of these reports were from the United States. Recently, we reported ch

The U.S. Government has developed a national strategy to address antimicrobial resistance, with one component being to monitor antimicrobial resistance in agricultural settings. We developed a survey to collect information about antimicrobial susceptibility testing (AST) from the veterinary diagnostic laboratory community in the United States, assessing current practices and technologies and determining how AST information is shared.
