Two types of cDNAs encoding carp SHBGs were isolated and characterized. Northern blot analysis showed their mRNAs distributed mainly in liver, and mRNA levels were almost constant during annual reproductive cycle. This result suggests SHBG synthesis is independent of serum steroid concentration. 相似文献

Identification of potent odorants in different green tea varieties using flavor dilution technique 总被引:1,自引:0,他引:1
Two kinds of pan-fired green teas (Japanese Kamairi-cha and Chinese Longing tea) were compared with the common Japanese green tea (Sen-cha). Application of the aroma extract dilution analysis (AEDA) using the volatile fraction of the Sen-cha, Kamairi-cha and Longing tea infusions revealed 32, 51, and 52 odor-active peaks with flavor dilution factors between 16 and 1024, respectively. (Z)-1,5-Octadien-3-one (metallic, geranium-like), 4-mercapto-4-methyl-2-pentanone (meaty, black currant-like), methional (potato-like), (E,Z)-2,6-nonadienal (cucumber-like), and 3-methylnonane-2,4-dione (green, fruity, hay-like) showed high flavor dilution factors in all varieties. In addition, 2-acetyl-1-pyrroline (popcorn-like), 2-ethyl-3,5-dimethylpyrazine (nutty), 2,3-diethyl-5-methylpyrazine (nutty), and 2-acetyl-2-thiazoline (popcorn-like) belonged to the most potent odorants only in the pan-fired green teas. Among these odorants, 2-acetyl-1-pyrroline and 2-acetyl-2-thiazoline were identified for the first time among the tea volatiles. 相似文献

To enhance the photostability of wood against ultraviolet (UV) light, a UV absorbent, 2,2,4-trihydroxy-4-[2-hydroxy-3-(3-trimethoxysilylpropoxy)propoxy]benzophenone (BP), was applied to the reaction system for preparing SiO2 wood–inorganic composites by sol–gel reaction. The BP–SiO2 wood–inorganic composites obtained were examined for photostability by scanning electron microscope observations, color changes, and diffuse reflectance infrared fourier transform analyses. The results clearly indicated that compared with SiO2 composites, BP–SiO2 composites improved the photostability of wood. In addition, BP was stable against UV light without degradation so that the BP–SiO2 composite should provide sustainable and high photostability of treated wood.Part of this report was presented at the 51st Annual Meeting of the Japan Wood Research Society at Tokyo, April, 2001 相似文献

Two hundred thirty one Staphylococcus aureus isolates from bovine mastitic milk were discriminated into 60 patterns and 16 lineages by pulsed-field gel electrophoresis (PFGE). The tested isolates were also investigated using coagulase and capsule serotyping and PCR for possession of genes that encode staphylococcal enterotoxins (sea to sei), enterotoxin-like toxins (selj to selr), and toxic shock syndrome toxin (tst). One hundred seventy three of the isolates (74.9%) possessed one or more toxin genes, while no egg-yolk factor was detected in most of them. The most common combinations of toxin genes possessed by the tested isolates were sec, seg, sei, sell, and tst, or seg and sei, or sec, seg, sei, sell, seln, and tst. Two hundred and ten of the isolates (91.0%) serotyped coagulase VI, and 207 of the isolates (89.6%) expressed serotype 5 or 8 capsules. These results suggested that isolates belonging to two major lineages have spread all over Hokkaido as bovine mastitic isolates. Additionally, no remarkable difference was recognized in the identification ratio of the isolates that belonged to the two major lineages between mastitis of subclinical origin and mastitis of clinical origin. 相似文献

The purposes of the present study were to evaluate the hepatocarcinogenicity of
concurrent treatment of 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline
(MeIQx) and diethylnitrosamine (DEN) in rats and to determine whether no effect levels of
combinations of these two different structural categories of genotoxic hepatocarcinogens
exist. Two 16-week rat hepatocarcinogenesis assays were performed using a total of 790
male F344 rats. In experiment 1, we evaluated the effects of concurrent treatment of a
subcarcinogenic dose of DEN on rat hepatocarcinogenesis induced by various doses of MeIQx.
In experiment 2, we determined hepatocarcinogenicities of combinations of MeIQx and DEN at
subcarcinogenic doses, low carcinogenic doses and high carcinogenic doses. Quantitative
analyses of glutathione S-transferase placental form (GST-P)-positive
foci, a preneoplastic lesion of the liver in rats, revealed that concurrent treatment with
subcarcinogenic doses of DEN did not enhance MeIQx-induced rat hepatocarcinogenicity. We
also found that concurrent treatment with combinations of subcarcinogenic doses of DEN and
MeIQx was not hepatocarcinogenic, indicating that the combined effects of subcarcinogenic
doses of DEN and MeIQx were neither additive nor synergistic. Moreover, concurrent
treatment with low carcinogenic doses of these 2 carcinogens did not show additive or
synergistic effects. Synergetic effects were observed only in rats coadministered high
carcinogenic doses of the 2 carcinogens. These results demonstrate the existence of no
effect levels of combinations of these 2 genotoxic hepatocarcinogens, and provide new
evidence supporting our idea that there is a threshold, at least a practical threshold,
that should be considered when evaluating the risk of genotoxic carcinogens. 相似文献

A questionnaire based on sensory evaluation of completely domestic grass‐fed beef was carried out on 157 Japanese undergraduate students aged between 18 and 22 years in Kitasato University. The sensory evaluation sheet consisted of 10 questions concerning preference for domestic grass‐fed beef, and three demographic/lifestyle questions. Using principal component analysis and cluster analysis, the respondents were divided into four groups (G1–G4). G1 accepted almost all properties. G2 accepted most properties but disliked chewiness. G3 accepted juiciness and flavor but disliked the color and texture of the meat. G4 tended to dislike almost all properties. According to chi‐square test, most G2‐people statistically liked other commercial beef and G4‐people had neutral and negative impressions. G1‐ or G3‐people did not have any significant tendency as regards beef preference. These results indicate that most of the young respondents who preferred domestic grass‐fed beef could not accept its texture, and some respondents could accept its juiciness and flavor. It is also suggested that a part of the people who like commercial beef do not prefer chewiness of grass‐fed beef. Such information will aid grass‐fed beef cattle breeders, producers and packers to improve the quality of beef and its evaluation. 相似文献
