The U.S. Congress has passed legislation requiring the EPA to implement screening tests for identifying endocrine-disrupting chemicals. A series of workshops was sponsored by the EPA, the Chemical Manufacturers Association, and the World Wildlife Fund; one workshop focused on screens for chemicals that alter thyroid hormone function and homeostasis. Participants at this meeting identified and e...
REM sleep behavior disorder (RBD) is a parasomnia characterized by dream-enacting behavior and vivid, action-filled or unpleasant dreams and presents a risk for self-injury and harm to others (e.g., a bed partner) due to abnormal REM sleep during which control of muscle tonus is lacking. Polysomnography is required to establish the diagnosis and represents the diagnostic gold standard for revea...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Recent advances in high-throughput protein structure determination and in computational chemistry have refocused attention on virtual screening and fast automated docking methods. This review provides a brief introduction to the basic ideas and outlines computational tools currently used. We also provide several examples of where virtual screening has proved successful, highlighting the usefuln...
Machine learning algorithms were applied to an electronic patient database generated by the UC Irvine Alzheimer's clinic to learn the simplest and most accurate patient parameters that would discriminate 244 very mildly demented from 198 normally aging subjects. Attributes included age, sex and education plus responses to the Functional Activities Questionnaire, the Mini-Mental Status and Bless...
We describe a model to examine the cost-effectiveness of various laboratory-screening approaches to detect methicillin-resistant Staphylococcus aureus (MRSA). A critical literature review was used to derive relevant data on the sensitivity (X), specificity (S) and time to result (T) of different tests. Additional cost information was provided by a hospital. Tests were considered in four interac...
background: there is a long lasting dilemma over the ideal screening and diagnostic method in gestational diabetes mellitus (gdm). even though universal screening is commonly practiced, selective screening based on risk factors is also practiced in some center. the aim of this study is to evaluate the most appropriate method to screen gdm in high‑risk pregnant women in sri lanka. methods: this ...
background: computerized preventive screening software is a cost effective intervention tool to address non-communicable chronic diseases. shiraz smart screening software (ssss) was developed as an innovative tool for qualified screening. it allows simultaneous smart screening of several high-burden chronic diseases and supports reminder notification functionality. the extent in which ssss affe...
background: colorectal cancer is the second cause of the cancer related mortalities in the world. screening can effectively reduce the mortality and morbidity rate of this cancer. sensitivity and specificity of screening methods play an important role in their efficacy. the aim of this study is to review sensitivity and specificity of selected colorectal cancer screening methods systematically....
