Recent studies have demonstrated that postponed weaning age from 6 weeks to 8 weeks in mink increases the number of bites among mink kits. Therefore, a series of studies have been conducted in order to quantify effects of weaning age on mortality, number of bites and growth rates in mink kits weaned at 42 and 56 days after birth during two consecutive breeding seasons. Partial weaning of large ...

BACKGROUND In 68% of foodborne disease outbreaks, no etiologic pathogen is identified. In two-thirds of outbreaks with no identified etiology, no stool specimens are submitted for testing. METHODS From April 2001 to March 2003, we pilot-tested use of prepackaged, self-contained stool specimen collection kits in 3 states, delivered to and from patients by courier or mail, to improve rates of s...

This research was aimed to develop and evaluate the activity based learning kits for children in a disadvantaged community according to the project “Vocational Teachers Teach Children to Create Virtuous Robots from Garbage”, to examine the learning achievement, to measure the satisfaction and to do an authentic assessment of children as regards the learning kits. The researchers chose the sampl...

I developed a standard procedure for assessing sensitivity, intra-assay precision, parallelism of sample dilutions, and assay drift, using a single trial assay kit. I used this to compare the performance of 10 commercial kits with an in-house radioimmunoassay for human thyrotropin. No one kit stood out as clearly superior overall. Differences in calibration between kits were evident in a compar...

Five commercial kits for the determination of folate and six kits for the determination of vitamin B12 were investigated. Their performance has been compared with microbiological methods for the two vitamins and with a non-commercial radioisotopic method for B12. The results show the importance of the determination of the reference range for an individual laboratory for each method. The precisi...

We have developed a genre of software construction kits and a framework for implementing them. The framework is both conceptual and structural. Its conceptual aspect derives from constructivist learning theory, and its structural aspect extends the Java Abstract Windowing Toolkit. This framework, called the “Kit4Kits,” supports generation of software kits that are highly graphical and highly in...

We evaluated four commercial kits for measuring serum ferritin, based on three techniques: immunoradiometric assay, radioimmunoassay, and enzyme immunoassay. The kits evaluated were those manufactured by Abbott Laboratories, Clinical Assays, Corning Medical, and Ramco. Two of the immunoradiometric kits showed satisfactory results with respect to sensitivity and precision; they should be useful ...

Objective: The reverse transcription–polymerase chain reaction test (RT-PCR) is the gold standard for diagnosis of coronavirus
 disease 2019 (COVID-19), and antibody tests are useful as supplemental tools diagnosis, measuring population’s immunity
 levels, checking infection in asymptomatic contacts. This study aimed to evaluate reliability five commercial antibody
 detection kit...
