Using BrUTP incorporation and statistical analysis, the authors investigated RNA transcription in the interphase nuclei in Physarum polycephalum Schw. The rRNA synthesis in the nucleolus continued actively throughout the interphase, while in nucleoplasm hnRNA was transcribed at law levels in S phase and actively in G(2) phase. The rate of nucleoplasm RNA transcription was doubled between early S phase and late S phase, and a 5-6 folds increase was detected between the early S phase and G(2) phase. 展开更多

[Objective] The aims of this study were to understand the flowering biological characteristics of Prunus domestica ×armeniaca and analyze its differences with other apricot varieties and plum varieties. [Method] Taking three varieties of Prunus domestica ×armeniaca as the research object, the phenophase of blooming,morphology characteristics of floral organs and development characteristics of floral organs were observed, pollen amount, pollen viability and stigma receptivity were measured. [Result] The results showed that three varieties of Prunus domestica×armeniaca were in blossom in early April, the florescence were relatively late for 8-12 d comparing with the varieties of apricot, the florescence were relatively similar to the P. domestica L. Morphology characteristics of floral organs of three varieties of Prunus domestica×armeniaca had few differences, were relatively similar to two varieties of plum, and they all had high percent of middle-style and long-style flower.The pollen amount of three varieties of Prunus domestica ×armeniaca had a little differences comparing with two varieties of plum, but were lower than three varieties of apricot. There were some differences in pollen viability, the germination percentage of pollen of ‘Konglongdan' was relatively high, was 51.6%; The pollen amount of ‘Fengweihuanghou' was relatively high, was 880.8 per anther; ‘Weidi' had fewer pollen amount, and the pollen viability was just 2.1%; Three varieties of Prunus domestica ×armeniaca all had strong stigma receptivity on the bloom day, and the stigma receptivity continued exist until the day that 5 days after blooming. [Conclusion] The florescence of three varieties of Prunus domestica ×armeniaca were relatively concentrated, and the rate of pistil abortion was lowest, the variation intensity of stigma receptivity and sustainable time of three varieties of Prunus domestica×armeniaca almost had a little differences comparing with a variety of plum, but slightly more than three varieties of apricot. 展开更多

[Objective] The aim of this study was to understand the flowering biological characteristics of different varieties Prunus domestica L. in Aksu Jiamu Experi- ment Station. [Method] Three varieties of plum as Prunus domestica L. cv. 'French', Prunus domestica L. cv. "Victoria' and Prunus domestica L. cv. "Stanley' were the research subjects. The phenophases of blooming, and the morphological and developmental characteristics of floral organs were observed. The amount and viability of pollen and the stigma receptivity were measured. [Result] Three varieties of plum all blossomed in early April, and the florescence had lasted for 9-10 d. The average number of anthers was 28.48%. The average number of pollen grains in each flower was 28 700.0. The pollen germination rate was 27.4%. 86.75% of the flowers were medium-styled or long-styled. There was no significant difference in the petal shape, color, anther number, calyx color, and flower ovary among the three varieties of plum. The stigma receptivity was strongest on the first day of flowering, and then dropped gradually. Therefore, the flowers of plum were manual pollinated on the first day of flowering. The duration time of stigma receptivity of Prunus domestica L. cv. 'Victoria' was longer than the other cultivars, the duration time of stigma receptivity was about 5 d. [Conclusion] The pollen number and pollen germination rate of Prunus domestica L. cv. 'Stanley' were higher than the other cultivars, which be considered the most suitable pollinizer for plum. In contrast, the complete flower rate of Prunus domestica L. cv. 'French' and Prunus domestica L. cv. 'Victoria' was relatively high, but the pollen number and pollen germination rate of Prunus domestica L. cv. 'French' and Prunus domestica L. cv. 'Victoria' were lower than Prunus domestica L. cv. 'Stanley', which are not suitable to use as a pollinizer for plum. 展开更多

AIM: To determine if surgical biliary bypass would provide improved quality of residual life and safe palliation in elderly patients with unresectable pancreatic head cancer. METHODS: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (Group A). These patients were compared with 19 patients under 65 years of age who were managed with surgical biliary bypass (Group B). In addition, the results for group A were compared with those obtained from 17 patients, 65 years of age or older (Group C), who received percutaneous transhepatic biliary drainage to evaluate the quality of residual life. RESULTS: Five patients (26.0%) in Group A had complications, including one intraabdominal abscess, one pulmonary atelectasis, and three wound infections. One death (5.3%) occurred on postoperative day 3. With respect to morbidity, mortality, and postoperative hospitalization, no statistically significant difference was noted between Groups A and B. The number of readmissions and the rate of recurrent jaundice were lower in Group A than in Group C, to a statistically significant degree (P = 0.019, P = 0.029, respectively). The median hospital-free survival period and themedian overall survival were also signifi cantly longer in Group A (P = 0.001 and P < 0.001, respectively). CONCLUSION: Surgical palliation does not increase the morbidity or mortality rates, but it does increase the survival rate and improve the quality of life in elderly patients with unresectable pancreatic head cancer. 展开更多

AIM: To share our surgical experience and the outcome of limited pancreatic head resection for the management of branch duct intraductal papillary mucinous neoplasm (IPMN). METHODS: Between May 2005 and February 2008, nine limited pancreatic head resections (LPHR) were performed for IPMN of the pancreatic head. We reviewed the nine patients, retrospectively. RESULTS: Tumor was located in the uncinate process of the pancreas in all nine patients. Three patients had stents inserted in the main pancreatic duct due to injury. The mean size of tumor was 28.4 mm. Postoperative complications were found in f ive patients: 3 pancreatic leakages, a pancreatitis, and a duodenal stricture. Pancreatic leakages were improved by external drainage. No perioperative mortality was observed and all patients are recorded alive during the mean follow-up period of 17.2 mo. CONCLUSION: In selected patients after careful evaluation, LPHR can be used for the treatment of branch duct type IPMN. In order to avoid pancreatic ductal injury, preand intra-operative defi nite localization and careful operative techniques are required. 展开更多

To fully make use of information from different representation subspaces,a multi-head attention-based long short-term memory(LSTM)model is proposed in this study for speech emotion recognition(SER).The proposed model uses frame-level features and takes the temporal information of emotion speech as the input of the LSTM layer.Here,a multi-head time-dimension attention(MHTA)layer was employed to linearly project the output of the LSTM layer into different subspaces for the reduced-dimension context vectors.To provide relative vital information from other dimensions,the output of MHTA,the output of feature-dimension attention,and the last time-step output of LSTM were utilized to form multiple context vectors as the input of the fully connected layer.To improve the performance of multiple vectors,feature-dimension attention was employed for the all-time output of the first LSTM layer.The proposed model was evaluated on the eNTERFACE and GEMEP corpora,respectively.The results indicate that the proposed model outperforms LSTM by 14.6%and 10.5%for eNTERFACE and GEMEP,respectively,proving the effectiveness of the proposed model in SER tasks. 展开更多

Several animal models of migraine have been established, and those based on trigeminovascular system activation are widely accepted. How- ever, most of these models have been established on lower animals, such as rodents, and involve only a single administration of a noxious stimulus. In this study, an inflammatory soup (10 μL), consisting of prostaglandin E2 (0.2 mM), serotonin (2 mM), bradykinin (2 raM) and histamine (2 raM), was injected into the dura mater of conscious rhesus monkeys through an indwelling catheter. The infusion started on day 8 and was repeated every 3 days, for a total of six administrations, to induce neurogenic inflammation. We performed behavioral assessments and measured the expression of the oncogene c-fos, neuronal nitric oxide synthase (nNOS) and calcitonin gene related peptide (CGRP) ill the trigeminal system and in multiple brain regions involved in pain processing by immunohistochemical staining. Compared with monkeys in the control group, three of the four animals in the inflammatory soup group displayed decreased motor behaviors, and two showed increased ipsilateral nose and mouth secretions during the stimulus period. Higher expression levels of c-fos, nNOS and CGRP were found in various brain areas of experimental animals compared with controls, including the trigeminal nucleus caudalis, thalamus, hypothalamus, midbrain, pons and other areas involved in pain perception. These results suggest that repeated inflammatory soup stimulation of the dura activates the trigeminovascular system and produces migraine-like pathological changes and abnormal behaviors in conscious rhesus monkeys. 展开更多

We fabricated long-period fiber gratings (LPFGs) using electric arc discharges. We observed that the fiber becomes slightly tapered due to longitudinal tension during the arc: this effect depends on the arc current and time length. We experimentally investigated how these characteristics can influence grating's performances, especially in view of employing the LPFG as gain equalizer for an erbium-doped optical amplifier. As expected, we found that the spectral response of the grating depends on the period A, the intensity of the perturbation, the grating length and the type of mode-coupling induced. Since this last parameter cannot be estimated directly from the transmission spectra, we propose a method to determine the modecoupling occurring in the device and to assess the index modulation induced by the electric arcs. This method combines both experimental and simulated data, and can be used to characterize LPFGs made-up by any method. 展开更多

The authors describe their experience with the management of the perioperative period, general anesthesia and the postoperative period in English bulldogs undergoing elective cesarean section and its effect on the neonates. The anesthetist for animals undergoing cesarean operation must be aware of any special needs, not only of the patient undergoing surgery, but also of the neonates. Anesthetic drugs administered to the pregnant patient will readily cross the placenta and affect them, with the exception of local anesthetics. Pregnant female patients are at increased anesthetic risk due to pregnancy-associated physiological alterations, such as altered pulmonary function. The anesthetist is often called to perform anesthesia on brachycephalic dogs for an elective cesarean section. Due to their conformation, these animals may have one or more anatomical abnormalities of the upper airways, which compromise the ability to ventilate adequately. The induction and recovery phases of anesthesia can be extremely dangerous in these patients, but the maintenance phase is generally fairly straightforward because the airways are controlled during maintenance In addition, vagal tone is frequently high and this can contribute towards significant bradycardia and further airway narrowing. All these reasons make general anesthesia in brachycepbalic dogs undergoing cesarean section rather complicated. 展开更多

AIM: To investigate whether the 7-difluoromethoxyl-5, 4'-di-n-octylgenistein (DFOG), a novel synthetic genistein analogue, affects the growth of gastric cancer cells and its mechanisms. METHODS: A series of genistein analogues were prepared by difluoromethylation and alkylation, and human gastric cancer cell lines AGS and SGC-7901 cultured in vitro were treated with various concentrations of genistein and genistein analogues. The cell viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The cells were incubated by DFOG at different concentrations. The growth inhibitory effects were evaluated using MTT and clonogenic assay. The distribution of the phase in cell cycle was analyzed using flow cytometric analysis with propidium iodide staining. The expression of the transcription factor forkhead box M1 (FOXM1) was analyzed by reverse transcription-polymerase chain reaction and Western blotting. The expression levelsof CDK1, Cdc25B, cyclin B and p27KIP1 protein were detected using Western blotting. RESULTS: Nine of the genistein analogues had more effective antitumor activity than genistein. Among the tested analogues, DFOG possessed the strongest activity against AGS and SGC-7901 cells in vitro. DFOG significantly inhibited the cell viability and colony formation of AGS and SGC-7901 cells. Moreover, DFOG efficaciously arrested the cell cycle in G2/M phase. DFOG decreased the expression of FOXM1 and its downstream genes, such as CDK1, Cdc25B, cyclin B, and increased p27KIP1 at protein levels. Knockdown of FOXM1 by small interfering RNA before DFOG treatment resulted in enhanced cell growth inhibition in AGS cells. Up-regulation of FOXM1 by cDNA transfection attenuated DFOG-induced cell growth inhibition in AGS cells. CONCLUSION: DFOG inhibits the growth of human gastric cancer cells by down-regulating the FOXM1 expression. 展开更多
