The method is linear in the range 1.0 to 100.0 ng mL-1 with correlation coefficients (R2) from 0.9960 to 0.9992. The limits of detection of four aflatoxins are in the range 0.18 to 1.50 ng mL-1 and the average recoveries range from 75.1 to 102.4%, with relative standard deviations (RSDs) less than 13.6%. This work presents the excellent extraction…[Read more]

Chondrosarcoma is the second most common primary bone malignancy, representing one fourth of all primary bone sarcomas. It is typically resistant to radiation and chemotherapy treatments. However, the molecular mechanisms that contribute to cancer aggressiveness in chondrosarcomas remain poorly characterized. Here, we studied the role of…[Read more]

After education, 12 patients (80%) chose to keep receiving PN and 3 patients (20%) changed their decision from PN to minimal hydration among the 15 patients. More calories were administered to patients who chosen PN (median 1,042.2 vs. 324.3 Kcal/day, P<0.001) for initial 7 days. Overall survival, scores of QLQ-C15-PAL, and symptoms were not…[Read more]

We evaluated (1) whether the sample transport time could lead to a significant loss of carbon through microbial respiration and to a change of measured respiration rates, which can be a problem in areas difficult to access, with a long travel time from field to laboratory; (2) whether the method used to quantify heterotrophic respiration for…[Read more]

Many of the states exhibited by B. subtilis are similar to states observed in other bacteria. What is special about B. subtilis is the unusually rich repertoire of alternative states exhibited by one bacterium, enabling it to cope with a wide range of environmental challenges.There is longstanding interest in studying microbial communities below…[Read more]

This study evaluated the reliability of MALDI-TOF MS coupled with statistical tools for the identification of Streptococcus mutans in comparison with PCR-based techniques. Bacterial isolates were identified and serotyped by conventional PCR, using S. mutans species and serotype-specific primers. For bacterial identification, mass spectra data from…[Read more]

Advanced methods for manufacturing high quality parts should be used to ensure the production of competitive products for the world market. Investment casting (IC) is a process where a wax pattern is used as a sacrificial pattern to manufacture high precision casting of solid metal parts. Rapid casting is in turn, a technique that eases the IC…[Read more]

Hematopoietic cell transplantation (HCT) is an effective treatment for many hematologic malignancies, and its utilization continues to rise. However, due to the difficult logistics and high cost of HCT, there are significant barriers to accessing the procedure; these barriers are likely greater for older patients. Although numerous factors may…[Read more]
