BACKGROUND Effectiveness of medical therapies in chronic pancreatitis has been described in small studies of selected patients. AIM To describe frequency and perceived effectiveness of non-analgesic medical therapies in chronic pancreatitis patients evaluated at US referral centres. METHODS Using data on 516 chronic pancreatitis patients enrolled prospectively in the NAPS2 Study, we evaluat...
Recently developed PCR-based reverse transcriptase (RT) assays are useful in the detection of retroviruses since they are approximately a millionfold more sensitive than conventional RT assays. However, these assays are both labor- and time-intensive. The previously described product-enhanced reverse transcriptase (PERT) assay involves a two-step RT-PCR followed by detection and quantitation of...
The GÉANT2 project established a Performance Enhancement and Response Team (PERT) process [1] in 2004 to assist network users in troubleshooting network performance issues and provide information on how to optimize network performance. This paper presents a summary and conclusions of a PERT case where the aim was to transfer data from an eVLBI radio telescope in Chile to the Netherlands across ...
This paper investigates the influence of the leg afferent input, induced by a leg assistive robot, on the decoding performance of a BMI system. Specifically, it focuses on a decoder based on the event-related (de)synchronization (ERD/ERS) of the sensorimotor area. The EEG experiment, performed with healthy subjects, is structured as a 3 × 2 factorial design, consisting of two factors: "finger t...
Quantification of retroviruses in cell culture supernatants and other biological preparations is required in a diverse spectrum of laboratories and applications. Methods based on antigen detection, such as p24 for HIV, or on genome detection are virus specific and sometimes suffer from a limited dynamic range of detection. In contrast, measurement of reverse transcriptase (RT) activity is a gen...
in order to study the genetic diversity of grapevine in mahneshan (zanjan) an experiment was performed during 2012 and 2013. in different phenological growth stages (bud burst, anthesis and fruit ripening) quantitative and qualitative characteristics of 12 genotypes (marageh, shahani, khalili, ag-ozom, germez keshmish, ag-keshmish, gara-keshmish, asghari, pert-pert, gezel-ozom and gandomeh) bas...
4-month-old twins were diagnosed with X-pert MTB/RIF® confirmed tuberculosis (TB)[...].
The use of uncertainty and criticality measures in network planning of engineering projects by PERT networks is limited in practice because of their unreliability or complexity. The measures appear as inappropriate to support the definition of contractual obligations when based on uncertain information. The author proposes new uncertainty and criticality measures based on the identification and...
The Qualitative Simulation Graph Methodology (QSGM) is well suited to address the PERT scheduling with resources problem. The coverage property of QSGM has two important implications for the PERT scheduling problem. First, it means that all possible schedules are represented. Second, it means that, as long as the delay time intervals are not violated, we can characterize all possible outcomes o...
