Baby hamster kidney fibroblasts (BHK21 cells) transformed by polyoma or Rous sarcoma viruses aggregate less than the untransformed parental cells when incubated in growth medium in a gyratory shaker for 18-24 h. This difference can be measured by electronic particle counting, or by filtering aggregated suspensions of 32P-labelled cells through bolting fabric. The aggregation of transformed deri...

In this study, analysis of dynamic characteristics and flight vibration was performed to unmanned aerial vehicles. The model supplemented by performing a characteristic test random using manufactured dummy vehicle. For the test, bungee cable used implement free end boundary condition. Prior multiple electric shaker, predict excitation force during actual test. It judged that could be predicted ...

The Drosophila Shaker K(+) channel is the first cloned voltage-gated potassium channel and has, therefore, played an important role in structural and functional studies of those channels. While such a role is well justified for ion permeation, it is not clear whether this also extends to ligand binding. Despite the high degree of homology among Shaker and Kv1 channels, κ-conotoxin PVIIA (κ-PVII...

The strength and dynamics of synaptic transmission are determined, in part, by the presynaptic action potential (AP) waveform at the nerve terminal. The ion channels that shape the synaptic AP waveform remain essentially unknown for all but a few large synapses amenable to electrophysiological interrogation. The Drosophila neuromuscular junction (NMJ) is a powerful system for studying synaptic ...

Skeletal muscle and liver tissue from 0,-day-old chick embryos were dissociated into separate cells using 0-25 % (w/v) crude trypsin. The effect of rabbit anti-actomyosin sera on the aggregation of these cells was estimated by the gyratory shaker and turbidimetric methods. Studies were also undertaken on the ability of fluorescein isothiocyanate-labelled rabbit anti-uterine actomyosin serum (FI...

The profitability of fresh citrus crops outlines the possibility using mechanical systems to reduce high cost manual harvesting operation. In this line, an experimental light shaker with low frequency and amplitude a hydraulic arm was developed. This device had been successfully used for ornamental trees. previous studies, it proven that removal percentage adequate, but slightly damaged fruit i...
