A bacterium belonging to the genus Spiroplasma, an endosymbiont of the fly Drosophila hydei, is vertically transmitted through host egg cytoplasm. To infer vertical transmission rates of Spiroplasma in natural populations of D. hydei, the infection status of Spiroplasma was examined for offspring produced by Spiroplasma-positive females that were collected in two geographical populations. In both populations, nearly half of the broods consisted of only infected offspring. Infection frequencies of the rest of the broods ranged from 0.364 to 0.975. Quantitative PCR demonstrated that the Spiroplasma titers in the whole body of wild-caught females were highly variable (1.81?×?106–5.60?×?108 cells per insect). Contrary to our expectations, however, the Spiroplasma titers did not account for the variation in infection frequencies among offspring (i.e., vertical transmission rates). These results suggest that the spatial distribution of Spiroplasma, particularly in somatic tissues and germ tissues, is highly variable among host individuals, which may be caused by environmental stochasticity or some unknown effects. 相似文献

Our previous report identified 27- and 29-kDa calcium-binding proteins in porcine immature dental enamel. In this study we
revealed that the N-terminal amino acid sequences of the two proteins were identical: LLANPXGXIPNLARGPAGRSRGPPG. The sequence
matches a portion of the amino acid sequence of the porcine sheath protein, sheathlin. Porcine tooth germs were investigated
immunochemically and immunohistochemically using specific antibodies raised against synthetic peptide that included residues
13–25 of this sequence. The affinity-purified antibodies reacted with several proteins extracted from newly formed immature
enamel in immunochemical analyses, especially protein bands migrating at 62, 35–45, 29, and 27 kDa in SDS-polyacrylamide gels.
The largest protein detected was a weak band near 70 kDa. In immunochemical analyses of proteins extracted from the inner
(old) immature enamel, the antibody reacted faintly with the 27- and 29-kDa proteins. In immunohistochemical preparations,
the Golgi apparatus and secretory granules of the secretory ameloblast, and the surface layer of immature enamel showed immunoreactivity.
The immunoreactivity of immature enamel just beneath the secretory face of the Tomes’ process was intense. No immunoreactivity
was found in the Golgi apparatus of the maturation ameloblast. These results suggest that the 70-kDa protein, whose degradation
might be very fast, is the parent protein of the 27- and 29-kDa proteins.

Energy harvesting from extremely low frequency magnetic fields using magneto‐mechano‐electric (MME) harvesters enables wireless power transfer for operating Internet of Things (IoT) devices. The MME harvesters are designed to resonate at a fixed frequency by absorbing AC magnetic fields through a composite cantilever comprising of piezoelectric and magnetostrictive materials, and a permanent magnetic tip mass. However, this harvester architecture limits power generation because volume of the magnetic end mass is closely coupled with the resonance frequency of the device structure. Here, a method is demonstrated for maintaining the resonance frequency of the MME harvesters under all operating conditions (e.g., 60 Hz, standard frequency of electricity in many countries) while simultaneously enhancing the output power generation. By distributing the magnetic mass over the beam, the output power of the harvester is significantly enhanced at a constant resonance frequency. The MME harvester with distributed forcing shows 280% improvement in the power generation compared with a traditional architecture. The generated power is shown to be sufficient to power eight different onboard sensors with wireless data transmission integrated on a drone. These results demonstrate the promise of MME energy harvesters for powering wireless communication and IoT sensors. 相似文献
