Contamination of folic acid assay medium with oleate led to a lag phase when Lactobacillus casei cultures were grown on folic acid but not when whole serum provided the folate source. This led to high assay values when using 20-hour incubation periods but satisfactory results were obtained after 48 hours' incubation. The addition of Tween 80 to the medium eliminated the lag phase and the assay ...

At the Annual Meeting in New Orleans on June 21–24 2014, the Institute of Food Technologists (IFT) will be celebrating their 75th anniversary. Our journal is a bit older, with Food Research (the precursor to the Journal of Food Science) publishing its first issue in January of 1936. Science has made tremendous progress in the past 75 years. One case in point occurred 60 years ago with the publi...

Aim: The influence of advanced age on the outcome repeat resections performed for colorectal liver metastasis (CLM) is ill-defined. We aimed to evaluate safety and efficacy recurrence CLMs in younger (≤70 years) elderly patients (70< years), define predictive factors survival.
 Material Method: A prospectively maintained database a single center including 291 CLM between 1998 2019 was a...

Reinforcement grades higher than 75 ksi (520 MPa) are not allowed in members that form plastic hinges due to a lack of information on material characteristics and on the seismic performance of columns constructed with high-strength steel (HSS) reinforcement. This research investigated the performance of reinforced concrete columns containing Grade 80 (minimum yield strength of 80 ksi [550 MPa])...
