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   

Correlation between Apgar score and urinary uric acid to creatinine ratio in perinatal asphyxia     

Pallab Basu  Sabyasachi Som  Nabendu Choudhuri  Harendranath Das 《Indian journal of clinical biochemistry : IJCB》2008,23(4):361-364

A randomized case control hospital based study was conducted over 12 months time on 31 asphyxiated and 31 normal newborn to see whether urinary uric acid can be used as a marker of perinatal asphyxia and can be correlated with the clinical diagnosis by Apgar score. Uric acid and creatinine were estimated in spot urine within 24 hours after birth in both cases and controls. A ratio between concentrations of uric acid to creatinine was estimated and compared between cases and controls. It was found that the ratios were significantly higher in cases than controls (3.1± 1.3 vs 0.96± 0.54; P < 0.001) and among asphyxia patients, a significant negative linear correlation was found between the uric acid to creatinine ratio and the Apgar score (r = −0.857, P < 0.001). So urinary uric acid to creatinine ratio can be used as an additional non-invasive dispace, easy and at the same time early biochemical marker of birth asphyxia which biochemically supports the clinical diagnosis and severity grading of asphyxia by Apgar score.  相似文献

Improving the Effectiveness of Fundraising Messages: The Impact of Charity Goal Attainment,Message Framing,and Evidence on Persuasion     

Enny Das  Peter Kerkhof  Joyce Kuiper 《Journal of Applied Communication Research》2013,41(2):161-175

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

Evidence‐based practice and teacher action‐research: a reflection on the nature and direction of ‘change’     

Laura Colucci‐Gray  Sharmistha Das  Donald Gray  Dean Robson  Jennifer Spratt 《British Educational Research Journal》2013,39(1):126-147

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   

Hyperhomocysteinemia, as an Independent Risk Factor for Retinal Venous Occlusion in an Indian Population     

Kapil D. Lahiri  Jayanta Dutta  Himadri Datta  Harendra N. Das 《Indian journal of clinical biochemistry : IJCB》2013,28(1):61-64

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   

Circadian Rhythm of Serum Cortisol in Female Patients with Fibromyalgia Syndrome     

Ghizal Fatima  Siddharth Kumar Das  Abbas Ali Mahdi  Nar Singh Verma  Faizan Haider Khan  Amit Mani Kumar Tiwari  Tabrez Jafer  Baby Anjum 《Indian journal of clinical biochemistry : IJCB》2013,28(2):181-184

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   

Hb Hope: A Rare Variant of Haemoglobin-Forged a Rise in HbA1c on Immunoturbidimetric Assay     

Bratati Singh  Debasis Debadatta Behera  Neelam Mehta  Seema Das 《Indian journal of clinical biochemistry : IJCB》2014,29(4):517-519

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   

Interrelationship Between Procalcitonin and Organ Failure in Sepsis     

Dimple Anand  Sabari Das  Sumit Ray  Seema Bhargava  Lalit Mohan Srivastava 《Indian journal of clinical biochemistry : IJCB》2014,29(1):93-96

Sepsis suffers from lack of specific clinical symptoms which contribute to one of the major causes of mortality. In the present study, our aim was to evaluate the role of a recent biomarker Procalcitonin (PCT) in predicting organ dysfunction. 71 patients admitted with sepsis were included in the study. PCT levels were measured at 0, 24, 72 h and 7th day and sequential organ failure assessment score (SOFA) scores were calculated. PCT levels significantly decreased (p < 0.001) in 89.3 % of surviving patients, whereas, in 60 % non surviving patients the PCT level increased significantly (p < 0.001). A significant positive correlation between PCT and SOFA score was observed in survivors at each hour. These observations indicate that PCT concentration is significantly associated with severity of multi organ dysfunction and also helps in determining the prognosis of septic patients.  相似文献
