In the current study, we investigated whether electroacupuncture (EA) can inhibit pathological reductions in neurogenesis. Zucker diabetic fatty (ZDF) rats at 7 weeks of age were anesthetized with zoletil, and sham-acupuncture or EA at the Zusanli (ST36) and Baihui (GV20) acupoints was administered once a day for 5 weeks. In the ZDF group that received sham-EA (ZDF-Sham group), the blood glucose level was significantly increased together with age as compared to the control littermates [Zucker lean control (ZLC) rat]. In contrast, proliferating cells and differentiated neuroblasts were significantly decreased in the ZDF-Sham group compared to the ZLC group. Although EA treatment decreased blood glucose levels, this was not statistically significant when compared to blood glucose levels changes in the ZDF-Sham group. However, proliferating cells and differentiated neuroblasts were significantly increased with EA in ZDF rats as compared to those in the ZDF-Sham group.
Brain-derived neurotrophic factor (BDNF) levels were significantly decreased in hippocampal homogenates of ZDF-Sham group compared to those in the ZLC group. The EA treatment significantly increased the BDNF levels compared to those in the ZDF-Sham group, and BDNF levels in this group were similar to those in the ZLC group. These results suggest that EA at ST36 and GV20 can ameliorate the reductions in proliferating cells and differentiated neuroblasts in the dentate gyrus induced by type-2 diabetes without significantly reducing blood glucose levels with increasing BDNF levels. 相似文献

A novel Helicobacter species was identified from the gastrointestinal tract of the Korean striped field mouse (Apodemus agrarius). Biochemical testing, ultrastructure characterization, and 16S rRNA gene sequence analysis suggested that this bacterium represents a distinct taxon. The bacterium was positive for urease activity, susceptible to cephalothin and nalidixic acid, and weakly positive for oxidase and catalase activity. Electron microscopy revealed that the bacterium has spirally curved rod morphology with singular bipolar nonsheathed flagella. Genotypically, the isolated bacterial strains (YMRC 000215, YMRC 000216, and YMRC 000419) were most closely related to a reference strain of Helicobacter mesocricetorum (97.25%, 97.32%, and 97.03% 16S rRNA sequence similarities, respectively). The 16S rRNA sequences of these strains were deposited into GenBank under accession numbers , AF284754, and AY009129, respectively. We propose the name Helicobacter apodemus for this novel species.

Abstract Field experiments with the “Taikichi” taro cultivar were conducted in volcanic ash soil of Kagoshima Prefecture, Japan, in order to determine the effects of potassium applied with fertilizers and manures on the growth and yield of taro. The experimental design was accord ing to the L27 (313) orthogonal factorial experiment, the three factors selected being the manures, nitrogen fertilizers and amount of potassium application. “Metsubure” corm formation was infrequent in hog manured plots without potassium application, but was significantly increased by the application of potassium fertilizer. Furthermore, the occurrence of “Metsubure” corms was significantly lower in fields prepared with hog manure than in those prepared with plant residue and cattle manure. Chemical analysis of the taro plants and manures revealed that the plants absorbed much more calcium when planted in hog manure than in other manures. The CaO/K2O ratio was also higher. The main reason for this was assumed to be the lower content of potassium in the hog manure (0.37% K2O on a dry basis). The analytic results suggest that potassium disturbs the calcium uptake ability of the taro plant causing “Metsubure” corm formation. The authors also attempted to determine the effects of several kinds of nitrogen fertilizers on “Metsubure” corm formation, but no clear results were obtained in this experiment. 相似文献

Radiography is a standard diagnostic test for characterizing left heart enlargement in dogs however limited information is available on the effects of respiratory phases. This prospective and retrospective method comparison study investigated the respiratory effect on the size and shape of the left heart in dogs to determine the usefulness of expiratory radiographs to detect enlargements in the left atrium (LA) and left ventricle (LV). Thoracic radiographs taken at full inspiration and expiration were evaluated in 20 normal beagles and 100 dogs diagnosed with mitral regurgitation (MR). Vertebral heart score (VHS), vertebral left atrial size, elevation of the carina, and dorsal bulging of LA on lateral view and lateral bulging of the left auricular appendage and LV on ventrodorsal view were assessed. In normal dogs, there were no significant differences in the evaluative factors between inspiration and expiration. In dogs with MR, VHS did not change according to respiration. However, bulging of the LA, left auricular appendage, and LV had sharp margin during expiration compared with inspiration. The expiratory radiographic finding of LA bulging had a higher correlation with the LA to aorta ratio compared with LA bulging in the inspiratory radiography. Using a LA to aorta echocardiographic ratio greater than 1.5 as the gold standard, the radiographic sensitivity for LA enlargement was higher during expiration than inspiration. These findings of our study indicated that expiratory radiography can be helpful to support the detection of left heart enlargement, although it can overestimate LA enlargement in dogs with MR. 相似文献

Miscanthus species are highly productive with low inputs and are excellent candidates for bioenergy feedstock production. A field experiment was conducted to characterize phenotypic differences in selected clones generated from interspecific hybrids of Miscanthus sinensis × Miscanthus sacchariflorus and intraspecific hybrids within M. sinensis. The field experiment was planted in plots of 20 m2 at a density of 1 plant m−2 in three randomized blocks. The trial was monitored for 3 years for traits important to biomass production including plant height, tiller density, tuft diameter and shoot diameter. ANOVA showed significant genotypic variation in these traits once the stand was 2 years old. This study shows that tillering and tuft diameter in years 1 and 2 are the most important traits influencing biomass yield, but over 3 years when the highest yielding potential is reached, tillering and tuft diameter have the highest correlation with biomass yield. These results identifying high-yielding Miscanthus clones will be utilized in our plant improvement program. 相似文献

OBJECTIVE: Despite the increasing dependence on systematic reviews to summarise the literature and to issue public health recommendations, the formal assessment of the reliability of conclusions emerging from systematic reviews has received little attention. The main goal of the present study was to evaluate whether two independent centres, in two continents, draw similar conclusions regarding the association of food, nutrition and physical activity and endometrial cancer, when provided with the same general instructions and with similar resources. DESIGN: The assessment of reproducibility concentrated on four main areas: (1) paper search and selection; (2) assignment of study design; (3) inclusion of papers; and (4) individual studies selected for meta-analysis and the summary risk estimate obtained. RESULTS: In total 310 relevant papers were identified, 166 (54 %) were included by both centres. Of the remaining 144 papers, 72 (50 %) were retrieved in the searches of one centre and not the other (54 in centre A, 18 in centre B) and 72 were retrieved in both searches but regarded as relevant by only one of the centres (52 in centre A, 20 in centre B). Of papers included by both centres, 80 % were allocated the same study design. Agreement for inclusion of cohort-type and casekey' papers was 87 %. Summary risk estimates from meta-analyses were similar. CONCLUSIONS: Transparency of process and explicit detailed procedures are necessary parts of a systematic review and crucial for the reader to interpret its findings. 相似文献

β‐Glucooligosaccharides (BGO), produced from barley β‐glucan, were used as a feed supplement (0.1%) for juvenile olive flounder (Paralichthys olivaceus) to identify and quantify its oral administration effects on innate immunomodulation and infectious disease protection. Juvenile flounders (14 ± 0.5 g) were divided into two groups fed either 0.1% BGO (treatment) or a standard diet (control) for 8 weeks. At the end of the experiment, investigation of the effects was carried out through systemic studies on growth performance, serum and mucus biochemical parameters, innate immunity, microvillus length, and relative pro‐inflammatory cytokine gene expression. The results demonstrated that the BGO diet produced slightly higher levels of growth performance, serum protein, microvillus length and pro‐inflammatory cytokine gene (tumour necrosis factor‐α, interleukin [IL]‐1β, and IL‐6) expression without any significant differences (p > .05). All innate immunity parameters were up‐regulated by BGO administration and, among these, respiratory burst, lysozyme and superoxide dismutase (SOD) were significantly different (p < .05). Fish in the both groups were challenged with Streptococcus iniae (1.35 × 108 CFU/ml), and BGO group was focused to confirm the promotion of innate immunity parameters. The results showed a significantly (p < .05) lower death rate compared with that of the control. Therefore, BGO could be used as a new prebiotic in future olive flounder aquaculture as well as to control streptococcosis. 相似文献

BACKGROUND: The relationship between the particle size of spray‐dried Bacillus thuringiensis NT0423 technical powder and its insecticidal activity against diamondback moth was investigated in laboratory and glasshouse conditions. A variety of sizes of Bt particles were made by homogenisation, followed by pilot‐scale milling to optimise further the current Bt formulation process. RESULTS: In laboratory conditions, homogenised Bt suspension with smaller particles had higher control efficacy against diamondback moth. However, in glasshouse conditions, the smallest particle treatment did not follow the size‐dependent insecticidal activity, rather showing decreased control efficacy. Secondly, air‐jet‐milled Bt powder (16.9 µm) had higher control efficacy than hammer‐milled Bt powder (35.1 µm) in glasshouse conditions. However, double air‐jet milling (5.3 µm) had lower control efficacy compared with one‐time milling. CONCLUSION: These results suggest that NT0423 technical powder with smaller particles is better in controlling diamondback moths, but excessively small particles (<10 µm) possibly reduce the insecticidal activity.
