Phenolics content of the untreated
cubes was 21.16 mg GAE/100 g on day-0, whereas treated samples had higher contents – 70.82, 40.58, and 25.98 mg GAE/100 g in AA-CA-Ca, SAS, and IR-5 samples, respectively. Similarly, antioxidant activities (ABTS, DPPH, FRAP, ORAC) generally increased with all treatments, this effect was more pronounced with AA-CA-Ca. Total phenolics and antioxidant activities were stable during 12-day storage at 4 degrees C. Cubes treated with AA-CA-Ca showed consistently better color and firmness than the control and other two treatments. Storage time and treatments showed a mixed trend on pH, soluble solids, acidity, and sugar-acid ratio.

“As an infrared Raman probe, the molecule 3,3′-diethylthiatricarbocyanine iodide (DTTC) has received Selleck CP 868596 much
attention in the past decades due to its potential applications in Raman imaging, single-cell detection, cancer diagnosis, and surface-enhanced Raman scattering (SERS). In this work, ordinary Raman, SERS, and theoretical Raman spectra were investigated to estimate the DTTC suspension. More specifically, the original gold nanospheres (60 nm diameter) and gold nanorods were encoded with DTTC and stabilized with a layer of thiol-polyethylene glycol as Raman reporter; SERS data were also obtained from the samples. Hartree-Fock theory and density functional theory (DFT) calculation were applied to calculate the optimized Raman spectra of DTTC in water on the B3LYP/6-31G level. Subsequently, the obtained experimental spectra from DTTC were carefully compared with the theoretically calculated spectra, and good agreement was obtained between the theoretical and experimental results. The bands between 500 and 3100 cm(-1) in the ordinary Raman and SERS spectra were assigned as well. This work will facilitate the development of ultrasensitive GW786034 SERS probes for advanced biomedical imaging applications. Copyright (C) 2011 John Wiley & Sons,”
“The goals of this cross-sectional study were to (a) describe the prevalence
of 5 basic social needs in a cohort of parents attending an urban teaching hospital-based pediatric clinic, (b) assess parental attitudes toward seeking assistance from their child’s provider, and (c) examine resident providers’ attitudes and behaviors toward addressing these needs. Parents (n = 100) reported a median of 2 basic needs at the pediatric visit. The most common was employment (52%), followed by education (34%), child care 19%), food (16%), and h(;using (10%). Most parents (67%) had positive attitudes toward requesting assistance from their child’s pediatrician. The majority of resident providers (91%) believed in the importance of addressing social needs; however, few reported routinely screening for these needs (range, 11% to 18%). There is great potential for assisting low-income parents within the medical home.
