Abstract

ABSTRACTThe ability of Grewia tenax fruit dried-ground (GTF-DG) as a source of antioxidants, and the influence of varying concentrations (0, 2, 4, and 6%) of GTF-DG on beef burger quality after 21 days of refrigerated storage, were explored. GTF-DG contained high phenolics and flavonoid contents and, therefore, displayed strong DPPH, radical ABTS, and ferric-reducing activity. The GTF-DG effectively stopped the development of bacterial strains at 100 g/disc. The burgers’ pH did not change significantly after the addition of GTF-DG. The burger’s antioxidant content and activity increased when GTF-DG was added at 4 and 6%, resulting in a significant decrease in microbial spoilage and lipid oxidation throughout the storage. GTF-DG caused a significant (p ≤ .05) improvement in burger cooking parameters. Burgers with 4% and 6% GTF-DG had higher sensory acceptance (p ≤ .05) than other treatments. In conclusion, burgers’ shelf life can be improved by the bioactive components in GTF-DG.

Abstract

In the next century, mankind will expand its activity to the moon and Mars. At that time, humans will be exposed to a low and micro-gravity environment in long term which causes physiological and psychological problems. The authors propose an artificial gravity space station for a research laboratory on human physiology and psychology at various gravity levels. The baseline specifications and the configuration of the space station are shown. Reviewing the history of manned space flight, the necessity of the research on an artificial gravity space station is discussed, including themes of research to be conducted on the station and the application of its results. Technical issues for realization of the space station such as environmental factors, system function and assembly scenario are also discussed.

9. The Association between Delivery during the COVID-19 Pandemic and Immediate Postpartum Maternal Cognitive Function.

Abstract

Survivors of the 2003 SARS epidemic were found to have higher rates of adverse mental conditions. This study aimed to assess cognitive function in women delivering during the COVID-19 pandemic, as compared to women who delivered before the COVID-19 pandemic. A cohort study was performed during the immediate postpartum period of women delivering singletons at term. Cognitive function was assessed using an objective neurocognitive test (Symbol Digit Modalities Test SDMT90, SDMT4) and a subjective self-estimation questionnaire (Attention Function Index AFI). The exposed group was recruited during the COVID-19 outbreak in Israel (May 2020), whereas the comparison group consisted of women delivering at the same medical center before the COVID-19 pandemic (2016-2017). Multivariable regression models were constructed to control potential confounders. There were 79 parturients recruited during the COVID-19 pandemic and compared with 123 women who delivered before the COVID-19 pandemic. Women delivering during the COVID-19 pandemic scored lower in the subjective AFI test compared to the unexposed group (70.0 ± 15.4 vs. 75.1 ± 14.7, p = 0.018). However, no significant difference was found in the objective SDMT tests scores. These results remained similar in the multivariable regression models when controlling for maternal age, ethnicity and time from admission to assessment, for AFI, SDMT90 and SDMT4 scores ( p = 0.014; p = 0.734; p = 0.786; respectively). While no significant difference was found in objective tests, our findings propose that the exposure to the COVID-19 pandemic is independently associated with a significant decrease in subjective maternal cognitive function during the immediate postpartum period.

Abstract

Objectives: To define reference levels for intraoperative radiation during stent insertion, ureteroscopy (URS), and percutaneous nephrolithotomy (PCNL); to identify variation in radiation exposure between individual hospitals across the UK, between low- and high-volume PCNL centres, and between grade of lead surgeon., Patients/subjects and Methods: In all, 3651 patients were identified retrospectively across 12 UK hospitals over a 1-year period. Radiation exposure was defined in terms of total fluoroscopy time (FT) and dose area product (DAP). The 75th percentiles of median values for each hospital were used to define reference levels for each procedure., Results: Reference levels: ureteric stent insertion/replacement (DAP, 2.3 Gy/cm 2 ; FT, 49 s); URS (DAP, 2.8 Gy/cm 2 ; FT, 57 s); PCNL (DAP, 24.1 Gy/cm 2 ; FT, 431 s). Significant variations in the median DAP and FT were identified between individual centres for all procedures (P < 0.001). For PCNL, there was a statistically significant difference between DAP for low- (<50 cases/annum) and high-volume centres (>50 cases/annum), at a median DAP of 15.0 Gy/cm 2 vs 4.2 Gy/cm 2 (P < 0.001). For stent procedures, the median DAP and FT differed significantly between grade of lead surgeon: Consultant (DAP, 2.17 Gy/cm 2 ; FT, 41 s) vs Registrar (DAP, 1.38 Gy/cm 2 ; FT, 26 s; P < 0.001)., Conclusion: This multicentre study is the largest of its kind. It provides the first national reference level to guide fluoroscopy use in urological procedures, thereby adding a quantitative and objective value to complement the principles of keeping radiation exposure 'as low as reasonably achievable'. This snapshot of real-time data shows significant variation around the country, as well as significant differences between low- and high-volume centres for PCNL, and grade of lead surgeon for stent procedures., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)
