Ictal electroencephalography (EEG) parameters in electroconvulsive therapy (ECT) for depression reportedly correlate with therapeutic response and stimulus dosage, particularly in right unilateral (RUL) ECT. The authors examined ictal EEG parameters as predictors of therapeutic effectiveness in bilateral (BL) sine and pulse wave ECT. A total of 30(More)
The nerve endings of the human acetabular labrum were investigated. Twenty-three acetabular labra were obtained from 24 fresh human cadavers, stained with Suzuki's silver impregnation and an immunohistochemical technique for neurogenic specific protein S-100, and examined by light and electron microscopy. Ramified free nerve endings were seen in all(More)
The Hamilton Rating Scale for Depression (HAMD) is the de facto international gold standard for the assessment of depression. There are some criticisms, however, especially with regard to its inter-rater reliability, due to the lack of standardized questions or explicit scoring procedures. The GRID-HAMD was developed to provide standardized explicit scoring(More)
Background Intimate relationships play an important role in the psychological and physical well-being of women during and after pregnancy. Our previous analyses demonstrated the significant role of marital relations on the woman's emotional status among a cohort of 61 married Japanese couples with a history of two consecutive spontaneous abortions.

(1'S)-acetoxychavicol acetate ((S)-ACA) exhibits chemopreventive effects on chemically induced tumor formation. It has been shown that ACA inhibited the development of azoxymethane-induced colon carcinogenesis through its suppression of cell proliferation in the colonic mucosa and its induction of glutathione S-transferase and quinone oxidoreductase 1 in(More)
Elucidation of the mechanisms underlying potential anticancer drugs continues and unraveling these mechanisms would not only provide a conceptual framework for drug design but also promote use of natural products for chemotherapy. The biological effects of (1'S)-acetoxychavicol acetate ((S)-ACA) have been widely investigated. However, in most cases, a(More)
The endosomal escape is a well-known serious obstacle for non-viral gene delivery. This is because of an acidic and enzymatic degradation of the contents of the endosome/lysosome. Therefore, the internalized gene needs to be efficient released into the cytosol to obtain the efficiently transfection efficiency. On the other hand, the diphtheria toxin T(More)
Naturally occurring symbioramide, (2S,3R,2'R,3'E)-N-(2'-hydroxy-3'-octadecenoyl)-dihydrosphingosine 1a, was synthesized from d-erythro-dihydrosphingosine (amino part, 2) and (2R,3E)-2-hydroxy-3-octadecenoic acid (acid part, 3a), both of which were prepared from l-serine. Its diastereomer, (2S,3R,2'S,3'E)-1b, having an enantiomer of the unnatural-type acid(More)
BACKGROUND Substance P (SP) is a multifunctional neuropeptide that transmits pain signals, regulates the immune system, and may modulate emotional stress. SP stimulates bone resorption activity of osteoclasts, and SP level in gingival crevicular fluid is correlated with the degree of periodontal inflammation. However, the exact roles of SP in bone(More)
