    Initiation of satellite cell replication in bupivacaine-induced myonecrosis (1994)

    Notes: Abstract To determine how and when the satellite cells are stimulated to replicate in muscle regeneration, the rat soleus muscle was examined chronologically after bupivacaine-induced myonecrosis. Bromodeoxyuridine and desmin-positive mononuclear cells, indicating the start of satellite cell replication, were seen 25 h after bupivacaine treatment when macrophages had already invaded the sarcoplasm of necrotic fiber. These findings suggest that muscle regeneration starts as early as the time at which macrophages begin to scavenge necrotic material. Proliferating myoblasts increased in number, reaching a maximum at 49 h after myonecrosis, and decreased in number 3 days after the myoblasts fused with each other to form myotubes. The satellite cell proliferation after bupivacaine-induced myonecrosis began at almost the same time as in crush injury, and earlier than after muscle transplantation using whole intact or minced muscle fragments. The earlier begining and more rapid regenerating process probably resulted from the preservation of intact satellite cells, blood vessels and peripheral nerves in the bupivacaine-induced myonecrosis.

    Cucumber mosaic virus-tolerant transgenic tomato plants expressing a satellite RNA (1992)
    Springer
    Theoretical and applied genetics 83 (1992), S. 679-683

    Notes: Summary A satellite RNA (T73-satRNA) gave reduced symptom severity on tomato plants when coinoculated with an ordinary strain of cucumber mosaic virus (CMVO). cDNA for T73-satRNA was introduced into a binary vector (pTOK162) through a homologous recombination in an Agrobacterium tumefaciens cell, and then transferred to leaf disks of tomato. Stable integration and transcription of the cDNA in the regenerants were verified by Southern and northern blot hybridizations, respectively. Upon inoculation with CMV-O, the transformants exhibited very slight symptoms of CMV, grew normally, and finally set fruits, whereas untransformed wildtype tomato plants showed very severe symptoms, and their growth was retarded and formed few fruits. Agarose gel electrophoresis of total RNA from CMV-O-inoculated transformants detected RNA molecules corresponding to T73-satRNA.

    Cluster cations ejected from liquid metal ion source: alkali metals (Li, Na) and group IV elements (Si, Ge, Sn, Pb) (1989)

    Notes: Abstract Cluster abundance of Li n + (n≤19), Na n + (n≤25), Si n z+ (n≤8 forz=1, 3≤n≤7 forz=2), Ge n z+ (n≤11 forz=1, 3≤n≤9 forz=2,n=4 forz=3), Sn n z+ (n≤7 forz=1, 3≤n≤9 forz=2,n=4 forz=3) and Pb n z+ (n≤6 forz=1, 5≤n≤7 forz=2) ejected from a liquid metal ion source has been investigated by mass spectrometry. The abundance spectra of alkali metal clusters showed distinct maxima and steps atn=3, 7, 9, 13 and 19 for Li, and atn=3, 5, 11, 13 and 19 for Na. Mass spectra of Si, Ge and Sn clusters were very similar each other, showing intensity drops aftern=4 and 6 (and alson=10 for Ge) for singly charged clusters. The magic numbers observed are discussed in terms of stability of charged clusters.

    Abundance of Na cluster ions ejected from a liquid metal ion source (1989)

    Notes: Abstract Sodium cluster ions Na+ n withn ranging up to 25 have been observed from a liquid sodium ion source by using a magnetic mass analyzer. Ion intensity as a function of cluster size showed distinct steps and local maxima atn=3, 5, 11, 13 and 19 (magic numbers), and a pronounced odd-even alternation. The features in the ion abundance curve are attributed to the relative stability of cluster ions. The observed magic numbers are only partially explained by the electronic shell model, indicating need to include a consideration of atomic structure in a cluster.

    Notes: Abstract Cluster ions of alloys (Li-Na, Li-Mg) have been produced by a liquid metal ion source (LMIS), and analyzed by mass spectrometry. For the Li-Na system, bimetallic clusters with various compositions were formed, and dominant bimetallic species were Na2Li+, NaLi+, NaLi 2 + and NaLi 8 + with this sequence of ion intensity. These clusters are systems containing 2 or 8 valence electrons except for NaLi+. For the Li-Mg, observed bimetallic clusters were limited to only three species (MgLi+, MgLi 2 + and Mg2Li+), but unexpectedly small multiply charged homonuclear clusters, Mg 2 2+ and Mg 3 2+ , were observed.

    Notes: Abstract Optical emission and absorption spectra from a growth zone in Cu smoke were measured by using a quartz prism spectrograph and a single-grating spectrophotometer. Atomic lines of Cu, band systems of Cu2 were observed. Two new band systems with 0–0 band heads at 252.88 and 238.79 nm were found. The continuous spectra due to Rayleigh scattering by fine particles were also observed. Variations of density of various species as a function of vertical position were revealed.
