Chronic pancreatitis, an irreversible inflammatory disease of the pancreas, is associated with the replacement of the destroyed
parenchyma by extended development of fibrosis. Despite marked progress in diagnostic tools, no consensus has been reached
in diagnosis of chronic pancreatitis. In this study we examined the hematological and biochemical parameters among 40 chronic
pancreatitis patients within 18 to 67 yrs. ESR level and ALP activity was elevated in 40% cases. Serum amylase activity increased
in 32 patients and it showed significant correlation with ALP (r=0.458, p=0.003), CA-19.9 (r=0.556, p<0.001), and calcium
level (r=−0.472, p=0.002). Type IV collagen level in chronic pancreatitis also elevated (164.4 ± 55.5 ng/ml) and showed negative
significant correlation with calcium level (r= −0.505, p=0.001). However, no significant correlation was observed between
amylase activity and type IV collagen (r=0.289, p= 0.07). 相似文献

Miniature replicas modeled after the Great Pyramid of Giza are believed to concentrate geoelectromagnetic energy within their
cavities and hence act as antistressors in humans and animals. Although there are not many reports of adverse effects of ‘overexposure’
in the pyramid, subjects have claimed to feel uneasy after certain duration of staying in the pyramid. The present study was
aimed to analyze the effects of prolonged pyramid exposure on plasma cortisol level, markers of oxidative damage and antioxidant
defense in erythrocytes of adult female Wistar rats. Rats were divided into three groups, normal controls (NC, n=6) that were
maintained under standard laboratory conditions in their home cages, pyramid exposed group-2 (PE-2, n=6) & pyramid exposed
group-4 (PE-4, n=6) where the rats were housed under the pyramid for 6 hours/day for 2 weeks and 4 weeks respectively. Plasma
cortisol and erythrocyte TBARS levels were significantly lower in both PE-2 and PE-4 rats and erythrocyte GSH levels and GSH-Px
activity were significantly higher in them as compared to the NC rats. There was no significant difference in the results
for these parameters between the PE-2 and PE-4 rats except for erythrocyte GSH-Px activity which was significantly more in
the PE-2 rats than in the PE-4 rats. Although these results don’t confirm any adverse effects of prolonged exposure in pyramids,
they indicate a possibility of such adverse effects. 相似文献

MXenes are one of the key materials for micro-supercapacitors (MSCs), integrating miniaturized energy-storage components with microelectronics. However, the energy densities of MSCs are greatly hampered by MXenes’ narrow working potential window (typically ≤0.6 V) in aqueous electrolytes. Here, we report the fabrication of high-voltage MXene-MSCs through the efficient regulation of reaction kinetics in 2D Ti3C2Tx MXene microelectrodes using a water-in-LiCl (WIL, 20 m LiCl) salt gel electrolyte. Importantly, the intrinsic energy-storage mechanism of MXene microelectrodes in WIL, which is totally different from traditional electrolytes (1 m LiCl), was revealed through insitu and exsitu characterizations. We validated that the suppression of MXene oxidation at high anodic potential occurred due to the high content of WIL regulating anion intercalation in MXene electrodes, which effectively broadened the voltage window of MXene-MSCs. Remarkably, the symmetric planar MXene-MSCs presented a record operating voltage of 1.6 V, resulting in an exceptionally high volumetric energy density of 31.7 mWh cm−3. With the ultra-high ionic conductivity (69.5 mS cm−1) and ultralow freezing point (−57°C) of the WIL gel electrolyte, our MSCs could be operated in a wide temperature range of −40 to 60°C, and worked for a long duration even at −40°C, demonstrative of its practicality in extreme environments. 相似文献

This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on research into social dilemmas, it was hypothesized that information about charity goal attainment (e.g., the contributions of others) should increase donation intentions. The hypotheses were tested in a 2 (goal attainment: yes/no)×2 (framing: positive/negative)×2 (evidence: statistical/anecdotal) factorial design. Abstract information was more effective when combined with a negatively framed message, whereas anecdotal information was more effective when combined with a positive frame. In addition, donation intentions were higher for messages that addressed charity goal attainment issues. 相似文献

This study was conceived as an opportunity to reflect on the place of action‐research in the contested landscape of educational change in the UK where increasing emphasis has been put on the use of evidence to drive reform. In the context of a government‐sponsored project in Scotland, this study looked at the impact of a scholarship initiative supporting classroom teachers to undertake action‐research projects on a topic of their own choice with the assistance of a mentor. Data collected from interviews with teachers and analysis of teacher action‐research reports pointed to a multi‐faceted concept of practice unfolding from individual inquiry and dialogical conversations with colleagues and university mentors. The study argues for further analysis of the use of action‐research as a means to develop teachers’ knowledge and to recover the value of collective and creative engagements in education to guide reform. 相似文献

Total plasma homocysteine was analysed in 64 cases of retinal vein occlusion (RVO) of which 24 cases of central retinal vein occlusion (CRVO) and 40 cases of branch retinal vein occlusion (BRVO) and compared with 45 age and sex matched control. Homocysteine was significantly increased in RVO cases in respect to control (P < 0.001). Analysis also revealed that prevalence of rise of plasma homocysteine was more in cases of CRVO (OR = 13) than that of BRVO (OR = 5.03). 相似文献

Fibromyalgia syndrome (FMS) patients have disturbed sleep patterns which may lead to altered circadian rhythm in serum cortisol secretion. The aim of this study was to assess circadian changes, if any, in serum cortisol levels in female patients with FMS. Cortisol levels were estimated every 6 h during 24 h period; in 40 female patients satisfying ACR criteria for FMS (Age 36.4 ± 9.9), and 40 healthy females without FMS (Age 33.8 ± 11.1). A significant difference in the night time serum cortisol level was observed among the patients and control groups (patients, 12.9 ± 9.7 controls 5.8 ± 3.0; p < 0.01). However, no significant difference was found in serum cortisol levels in patients and control groups in the morning (patients, 28.4 ± 13.2 controls, 27.6 ± 14.5; p > 0.05), afternoon (patients, 14.4 ± 5.6 controls, 14.0 ± 6.6; p > 0.05) and evening hours (patients, 10.9 ± 5.8 controls, 8.9 ± 3.6; p > 0.05). It could be concluded that there is an abnormality in circadian secretion of cortisol in female FMS patients. 相似文献

Glycosylated hemoglobin (HbA1c) determination is a powerful means for assessing the evaluation and management of patients with diabetes mellitus. Hemoglobin (Hb) variants and chemically modified derivatives of Hb can affect the accuracy of measurement of HbA1c done by various analytical methods. We report a patient with a rare variant of Hb (Hb Hope) that caused an abnormally high value of HBA1c when assayed using immunoturbidimetric assay (“Tina-quant” 2nd generation assay) and also elucidate the nature of the variant. 相似文献
