Plants also use ABC transporters, particularly NtPDR1, to actively transport antimicrobial metabolites. (7) Plants also employ active transport when they absorb nutrients (e.g. chlorine and nitrates) from the soil into the vacuole. In humans and animals, active transport is employed in many ...

Active transport can contribute to total physical activity and thus affect body weight because of increased energy expenditure. This review summarizes published evidence on ...
The characteristics of ATP-dependent transport of acetylcholine (ACh) in homogenates of pheochromocytoma (PC-12) cells stably transfected with the human vesicular acetylcholine transporter (VAChT) cDNA are described. The human VAChT protein was abundantly expressed in this line and appeared as a diffuse...
The Ca(++) transport mechanism in the red cell membrane was studied in resealed ghost cells. It was found that the red cell membrane can transport Ca(++) from inside the cell into the medium against great concentration gradient ratios. T... KS Lee,BC Shin - 《Journal of General Physiolog...
Yet, the existence and importance of cholesterol degradation pathways in humans is a matter of debate. We quantified cholesterol fluxes in 15 male volunteers using a cholesterol balance approach. Ten participants repeated the protocol after 4 weeks of treatment with ezetimibe, an inhibitor of ...
the potential to improve the ability of animals to resist mammary infections, enhance the transfer of passive immunity from mother to young and increase the feasibility of harvesting antibodies from the mammary secretions for use in commercial therapeutic applications for humans and domesticated animals....
Additional strategies to promote ATS and physical activity are needed in rural areas because of long commuting distances for many students. 展开 关键词: Humans Data Collection Linear Models Seasons Rural Population Adolescent Child Walking Residence Characteristics Schools ...
At the mean age of 58 years, at least 25% of the installation, auxiliary, or transport workers had a poor work ability rating, as did the women doing kitchen supervision, auxiliary, and home care work. The annual rate of decline in work ability was highest for women aged 51 years at ...
Sickle red blood cells (RBCs) have been shown to have an increase in total nicotinamide adenine dinucleotide (NAD) content by an as-yet-unknown mechanism. Because glutamine is an essential precursor in NAD biosynthesis, we have examined the rates of active RBC glutamine transport and glutamine tr...
Table 1 Summary of centrosomal mRNAs in humans and theirDrosophilaorthologs. Full size table ASPM, NUMA1, and HMMR proteins localize to centrosome at specific cell cycle stages We then focused onASPM,NUMA1, andHMMR, and analyzed in more detail their expression and localization. We first analyzed...
