Intracortical connectivity was studied in slice preparations of cat's visual cortex by spike-triggered averaging. The experiments documented the unitary postsynaptic potentials underlying the inhibitory and excitatory connections from layer III-IV border cells to supragranular cells, as demonstrated previously by cross-correlation studies. In addition the(More)
Clinical and immunohistochemical studies were done for 3-39 d on mice after intracerebral inoculation with the neurovirulent A/WSN/33 (H1N1; WSN) strain of influenza A virus, the nonneurovirulent A/Aichi/2/68 (H3N2; Aichi) strain, and two reassortant viruses between them. The virus strains with the WSN gene segment coding for neuraminidase induced(More)
The effects of acetylcholine on cultured hippocampal neurons were investigated by using the whole-cell version of the patch-clamp technique. The CA1 region of the hippocampus was excised from brain slices of young rats (12-19 day old), incubated in a papain solution, and dissociated. Neurons were plated on a glial feeder layer. The experiments were(More)
We have developed dissociated primary neuronal cultures obtained from the substantia nigra and from the ventral tegmental area of postnatal rats (two to three days old). After making brain slices, the regions of the substantia nigra and the ventral tegmental area were separately dissected. The removed fragments of brain tissue were dissociated and cultured(More)
Tumour angiogenesis, as assayed by microvessel density (MVD), and the expression of vascular endothelial growth factor (VEGF) and platelet-derived endothelial cell growth factor (PD-ECGF) have become established as important prognostic indicators for many tumour types. In this study, MVD and the expression of VEGF and PD-ECGF were examined by(More)
Mammalian target of rapamycin (mTOR) has a key role in the regulation of an array of cellular function. We found that rapamycin, an inhibitor of mTOR complex 1 (mTORC1), attenuated endoplasmic reticulum (ER) stress-induced apoptosis. Among three major branches of the unfolded protein response, rapamycin selectively suppressed the IRE1-JNK signaling without(More)
Non-homologous end joining (NHEJ) is a major repair pathway for DNA double-strand breaks (DSBs) generated by ionizing radiation (IR) and anti-cancer drugs. Therefore, inhibiting the activity of proteins involved in this pathway is a promising way of sensitizing cancer cells to both radiotherapy and chemotherapy. In this study, we developed an assay for(More)
PURPOSE The aim of this study was to evaluate the outcome, with a special reference to recurrence and postoperative chronic pain, of the modified Kugel herniorrhaphy (MKH) using standardized dissection of the preperitoneal space. PATIENTS AND METHODS Operative results were examined based on medical records and questionnaire surveys in 340 consecutive(More)
We have reported previously that the human vitamin D receptor (hVDR) is selectively phosphorylated by protein kinase C-beta (PKC-beta), in vitro, on a serine residue in the sequence RRS51MKRK, which is located between the two zinc fingers of hVDR and is potentially important to its transacting function (Hsieh, J.-C., Jurutka, P.W., Galligan, M.A.,(More)
