Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: The mechanics of material solution is a coarse analytical solution on the problem of simply supported beam under uniform load. This paper intends to determine the relative error of the mechanics of material solution. Solutions according to plane stress theory of elasticity theory are believed to be the true solution. Results indicate that material mechanics solution σx seems applicable only when the ratio of beam height to beam length is less than 0.1 and the ratio of distance between beam studied cross section and midpoint in x direction to beam length is less than 0.49. When the ratio of beam height to beam length is less than 0.1 and the ratio of distance between beam studied cross section and midpoint in x direction to beam length is less than 0.49, maximum value of relative error for material mechanics solution σx is no more than 12%. Material mechanics solution τxy is always correct for the problem of simply supported beam under uniform load. Material mechanics solution σx is not applicable for the problem of simply supported beam under uniform load.

Abstract: Objective: To study the effects of triptolide-medicated serum on secretory function of adrenocortical cells isolated from rats. Methods: Thirty SD rats were randomly divided into control group, prednisone group, and low-, medium- and high-dose triptolide groups. Rats were administered with normal saline, prednisone and low-, medium- and high-dose triptolide respectively by gastrogavage to prepare sera containing drugs. Primary adrenocortical cells were isolated from normal male rats and cultured with sera containing drug for 48 hours. Expression of proliferating cell nuclear antigen (PCNA) was observed by immunohistochemical method and number of PCNA-positive cells was counted. Ultrastructure of adrenocortical cells was observed under a transmission electron microscope. Content of corticosterone in supernatant of adrenocortical cell culture was detected by enzyme-linked immunosorbent assay, and real-time fluorescence quantitative polymerase chain reaction (PCR) was employed to investigate the expression of 3β-hydroxysteroid dehydrogenase (3β-HSD) mRNA.Results: As compared with the control group, content of corticosterone in supernatant of adrenocortical cell culture and expression of 3β-HSD mRNA were significantly increased in the triptolide-treated groups, and the numbers of PCNA-positive cells were increased in the medium- and high-dose triptolide groups, however, they were decreased in the prednisone group.Conclusion: Triptolide-medicated serum can increase the secretion of corticosterone in rat adrenocortical cells in vitro.
Dark Energy, Hyperbolic Cosecant Cardassian and Virial Collapse for Power-style Cardassian

Physics , 2009,
Abstract: New work gathers in Chapter 6 and Chapter 7. Tthe Cardassian dynamical equations are introduced generally and logically under GF fluid scenario, together with the flowing process of constructing phase space and differential dynamical systems from Friedmann equation. Hyperbolic cosecant Cardassian term is employed for concrete computing. The analysis proceeds in two cases, namely a unified description of matter and radiation energy density (case 1) and a separate description of matter and radiation terms (case 2).Formalism of case 2 is more exact at the expense of more complicatedness, and due to the mathematical symmetry of matter term and radiation term in hyperbolic cosecant function, the differential dynamical equations are considerably simplified. Phase space and dynamical systems for both cases are achieved. When we calculate the critical points for case 2, amazingly interesting behaviors of self-consistency and auto-normalization are exhibited, which is a strong support for the new model,along with a forever positive sound speed. The process of virial collapse in Cardassian cosmos is analyzed. Power-style Cardassian term is employed for its simplicity.Calculation declares that virial collapse of matter alone isforbidden. Yet Cardassian has excellent ability for virial collapse,after the virial collapse ending up with a stable sphere, the ratio of the ultimate radius to the original radius depends on the adjustable parameters in Cardassian term. And, the mixture of GF fluid and matter could conduct virial collapse, the ratio of the ultimate radius to the original radius depends on the adjustable parameters in Cardassian term, too. No singularity is generated.

Abstract: Co3O4/CeO2 catalysts were prepared by co-precipitation-oxidation method and characterized by using X-ray diffraction(XRD),surface area(SBET) measurement and temperature-programmed reduction(TPR).The effect of cobalt content in Co3O4/CeO2 on its physical properties and catalytic performance in CO oxidation was investigated under both the humid and dry conditions.The results indicated that the Co3O4/CeO2 composite with a Co/Ce atomic ratio of 9(calcined at 723 K) exhibits much smaller particle size and higher surface area than pure Co3O4;the addition of cerium to Co3O4 is beneficial to obtain Co3O4 with small particle size.The average particle size and BET surface area of Co3O4 in the Co3O4/CeO2 composite(Co/Ce atomic ratio = 9) calcined at 538 K are 7.2 nm and 167.6 m2/g,respectively.Accordingly,the Co3O4/CeO2 composite exhibits excellent redox property.

Plasma D-Dimer Levels Are Associated with Stroke Subtypes and Infarction Volume in Patients with Acute Ischemic Stroke
Wen-Jie Zi, Jie Shuai
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0086465
Abstract: Background It has been suggested that modestly elevated circulating D-dimer values may be associated with acute ischemic stroke (AIS). Thus, the purpose of this study was to investigate the association between plasma D -dimer level at admission and AIS in Chinese population. Methods In a prospective observational study, plasma D-dimer levels were measured using a particle-enhanced, immunoturbidimetric assay on admission in 240 Chinese patients with AIS. The National Institutes of Health Stroke Scale (NIHSS) score was assessed on admission blinded to D-dimer levels. Results Plasma median D-dimer levels were significantly (P = 0.000) higher in AIS patients as compared to healthy controls (0.88; interquartiler range [IQR], 0.28–2.11 mg/L and 0.31; IQR, 0.17–0.74 mg/L). D-dimer levels increased with increasing severity of stroke as defined by the NIHSS score(r = 0.179, p = 0.005) and infarct volume(r = 0.425, p = 0.000). Those positive trends still existed even after correcting for possible confounding factors (P = 0.012, 0.000; respectively). Based on the Receiver operating characteristic (ROC) curve, the optimal cut-off value of plasma D-dimer levels as an indicator for diagnosis of cardioembolic strokes was projected to be 0.91 mg/L, which yielded a sensitivity of 83.7% and a specificity of 81.5%, the area under the curve was 0.862(95% confidence interval [CI], 0.811–0.912). Conclusion We had shown that plasma D-dimer levels increased with increasing severity of stroke as defined by the NIHSS score and infarct volume. These associations were independent other possible variables. In addition, cardioembolic strokes can be distinguished from other stroke etiologies by measuring plasma D-dimer levels very early (0–48hours from stroke symptom onset).
Cortisol as a Prognostic Marker of Short-Term Outcome in Chinese Patients with Acute Ischemic Stroke
Wen-Jie Zi, Jie Shuai
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0072758
Abstract: Background Early prediction of outcome is important for allocation of therapeutic strategies. Endocrine alterations of the hypothalamus–pituitary–axis are one of the first stress-induced alterations after cerebral ischemia. We therefore evaluated the prognostic value of serum cortisol in Chinese patients with an acute ischemic stroke. Methods In a prospective observational study, serum cortisol was measured using a solid-phase, competitive chemiluminescent enzyme immunoassay on admission in serum of 226 consecutive Chinese patients with an acute ischemic stroke. The prognostic value of serum cortisol to predict the functional outcome, mortality within 90 days, was compared with clinical variables (e.g., advanced age and the National Institutes of Health Stroke Scale [NHISS] score) and with other known predictors. Results Patients with a poor outcome and nonsurvivors had significantly increased serum cortisol levels on admission (P<0.0001, P<0.0001). There was a positive correlation between levels of cortisol and the NIHSS (r = 0.298, P<0.0001), glucose levels (r = 0.324, P<0.0001) and infarct volume (r = 0.328, P<0.0001). Cortisol was an independent prognostic marker of functional outcome and death [odds ratio 3.44 (2.58–6.23) and 4.21 (1.89–9.24), respectively, P<0.0001 for both, adjusted for age, the NIHSS and other predictors] in patients with ischemic stroke. In receiver operating characteristic curve analysis, cortisol could improve the NIHSS score in predicting short-term functional outcome (Area under the curve [AUC] of the combined model, 0.87; 95% CI, 0.82–0.92; P = 0.01) and mortality (AUC of the combined model, 0.90; 95% CI, 0.84–0.95; P = 0.01). Conclusion Cortisol can be seen as an independent short-term prognostic marker of functional outcome and death in Chinese patients with acute ischemic stroke even after correcting confounding factors. Combined model can add significant additional predictive information to the clinical score of the NIHSS.
Temporal Sequence of Visuo-Auditory Interaction in Multiple Areas of the Guinea Pig Visual Cortex
Masataka Nishimura, Wen-Jie Song
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0046339
Abstract: Recent studies in humans and monkeys have reported that acoustic stimulation influences visual responses in the primary visual cortex (V1). Such influences can be generated in V1, either by direct auditory projections or by feedback projections from extrastriate cortices. To test these hypotheses, cortical activities were recorded using optical imaging at a high spatiotemporal resolution from multiple areas of the guinea pig visual cortex, to visual and/or acoustic stimulations. Visuo-auditory interactions were evaluated according to differences between responses evoked by combined auditory and visual stimulation, and the sum of responses evoked by separate visual and auditory stimulations. Simultaneous presentation of visual and acoustic stimulations resulted in significant interactions in V1, which occurred earlier than in other visual areas. When acoustic stimulation preceded visual stimulation, significant visuo-auditory interactions were detected only in V1. These results suggest that V1 is a cortical origin of visuo-auditory interaction.
