Translation and Linguistic Validation of the Assessment of Physical Activity in Frail Older People into Simplified Chinese Using Cognitive Interviewing Methodology.

The Assessment of Physical Activity in Frail Older People (APAFOP) is a patient-reported outcome measure assessing physical activity among community-dwelling older adults. However, this instrument has not been verified in the Chinese context. Thus, we translated the APAFOP into Chinese and then linguistically validated the Chinese version of APAFOP (APAFOP-C) by following the guidelines developed by Beaton and Willis.

The proteome and phosphoproteome of maize pollen uncovers fertility candidate proteins.

Maize is unique since it is both monoecious and diclinous (separate male and female flowers on the same plant). We investigated the proteome and phosphoproteome of maize pollen containing modified proteins and here we provide a comprehensive pollen proteome and phosphoproteome which contain 100,990 peptides from 6750 proteins and 5292 phosphorylated sites corresponding to 2257 maize phosphoproteins, respectively. Interestingly, among the total 27 overrepresented phosphosite motifs we identified here, 11 were novel motifs, which suggested different modification mechanisms in plants compared to those of animals.

[A preliminary study of the inhibitive efficacy of iodized linoleic acid and its fluorodeoxyuridine ester in hepatocellular cancer].

Objective: To explore the potential of iodized linoleic acid (ILA) and its 5-fluoro-deoxyuridine ester (IFU) to inhibit hepatocellular carcinoma (HCC) cells in vitro and tumors in vivo.

Methods: ILA and its constituent component IFU were chemically synthesized, purified, and confirmed by 1H-NMR. The HCC cell lines, QGY-7703 (5-fluorouracil (5-FU) treatment sensitive) and SMMC-7721 (5-FU resistant), were treated with ILA, IFU, 5-FU, or traditional lipiodol for 72 hours.

[Responses of spring corn growth and yield in a cold area of China to field warming at nighttime during pre-anthesis stage].

By using the facility for increasing free air temperature, a field experiment was conducted in a cold area of Northeast China to study the responses of the growth and yield of rain-fed spring corn to the field warming at nighttime during pre-anthesis stage. Under the field warming at nighttime, the nighttime temperature in 0-10 cm soil layer increased by 1.7 degrees C, and the soil moisture content had a slight decrease.
