The aim of this study was to investigate the influence of serial mouth rinsing (MR) with nutritional supplements on cognitive performance (i.e., cognitive control and time perception) during a 40-min submaximal exercise. Twenty-four participants completed 4 counterbalanced experimental sessions, during which they performed MR with either placebo (PL), carbohydrate (CHO: 1.6 g/25 mL), guarana co...

Microfiltration is a ubiquitous and often crucial part of many industrial processes, including biopharmaceutical manufacturing. Yet, all existing filtration systems suffer from the issue of membrane clogging, which fundamentally limits the efficiency and reliability of the filtration process. Herein, we report the development of a membrane-less microfiltration system by massively parallelizing ...

We recently established a novel co-culture assay system using activated inflammatory cells and AS52 Chinese hamster ovary cells, and demonstrated that reactive oxygen and nitrogen species (RONS) generated from activated inflammatory leukocytes induce mutations in the gpt recorder gene in AS52 cells. In this study, we examined the inhibitory effects of 19 agents with antioxidative properties on ...

UNLABELLED Carbohydrate-protein (CHO+Pro) beverages reportedly improve endurance and indices of muscle disruption, but it is unclear whether these effects are related to total energy intake or specific effects of protein. PURPOSE The authors examined effects of CHO+Pro on time to exhaustion and markers of muscle disruption compared with placebo (PLA) and carbohydrate beverages matched for car...

In this paper we present a model of endogenous trade-policy formation which captures crucial aspects of the Japanese commercial and political culture. We analyze the influence of the portrayed cultural traits and show that cultural idiosyncrasies are important determinants of trade policy formation; especially the complex interaction of the two types of cultures is shown to have significant con...

Chinese hamster ovary cells synchronized by mitotic detachment were treated with 5-fluorodeoxyuridine (FdUrd), 0.2 micrograms/ml, at various times in the cell cycle. FdUrd treatment in the early S period induced resistance to 6-thioguanine. Treatment of asynchronous cells with FdUrd caused little increase in 6-thioguanine resistance over the spontaneous frequency. Mitotic selection thus enhance...

The dihydrofolate reductase (DHFR) and 2BE2121 genes in the Chinese hamster are convergently transcribed in late G1 and ea ly S phase, and bracket an early-firing origin of replication that consists of a 55-kb zone of potential initiation sites. To test whether transcription through the DHFR gene is required to activate this origin in early S phase, we examined the two-dimension (2D) gel patter...

The 45-kilobase tetracycline resistance plasmids pMAK175 and pUA466 from Campylobacter jejuni were examined using curing and mating experiments. However, these plasmids encoded neither cytotoxin production, as determined in Vero cells, nor enterotoxin activity, as determined in Chinese hamster ovary cells.
