Pathogenesis of coronary artery disease (CAD) is multi-factorial and several conventional risk factors have been ascribed; LDL-C being one of the important risk factor. However Indian population studies with established CAD often show LDL levels within normal range in patients with proven CAD. We hypothesized that Small dense low density lipoprotein (sdLDL) being more atherogenic might correlate more strongly to the occurrence and severity of CAD. The aim of the study was to evaluate the association between serum small dense LDL level and angiographically documented coronary artery disease. This is a cross sectional case control study in which sdLDL were measured in 126 patients with CAD and in 64 patients without CAD. Total cholesterol, HDL Cholesterol, LDL cholesterol and triglycerides were measured by standard methods along with other traditional risk factors. Direct quantitative measurement of sdLDL was done by enzymatic analysis. Mean sdLDL level was higher in patients with coronary stenosis than patients without coronary stenosis (16.3 ± 6.8 vs. 10.1 ± 5.7 mg/dL respectively, (p < 0.001). There was significant correlation between mean sdLDL and severity of CAD as assessed by syntax score with mean sdLDL level in low, intermediate and high syntax score being 15.0 ± 5.8, 20.1 ± 6.7 and 22.7 ± 7.3 mg/dL respectively (p value <0.001). A cut off value of 10.02 mg/dL was associated with presence of CAD (95 % CI 0.82–0.93, p < 0.001) using ROC curve. In conclusion Indian patients with established CAD have higher sdLDL levels compared to individuals without CAD despite having comparable LDL levels.  相似文献   

Can dams and reservoirs cause earthquakes?   总被引：1，自引：0，他引：1  

Ramesh Chander 《Resonance》1999,4(11):4-13

No! Not on their own. But, stresses and pore pressure due to natural causes may already have accumulated in crustal rocks at some dam sites to near critical levels for fresh faulting or renewed slip on nearby pre-existing faults. The stresses and pore pressure induced by impoundment of reservoirs there may marginally abet the tendencies to such failures and even trigger or induce earthquakes by being the proverbial last straw.  相似文献   

Antioxidant Activities of Hydroalcoholic Extract of <Emphasis Type="Italic">Ocimum sanctum</Emphasis> Against Cadmium Induced Toxicity in Rats     

Ramesh B  Satakopan VN 《Indian journal of clinical biochemistry : IJCB》2010,25(3):307-310

The present study was undertaken to analyze the antioxidant (both enzymic and nonenzymic) activities of leaves of Ocimum sanctum hydroalcoholic extract against cadmium induced damage in albino rats. Oral administration of cadmium as CdCl₂ (6.0 mg/kg body weight) led to significant elevation of lipid peroxidation (LPO) levels and significantly decreased Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), Reduced Glutathione (GSH) and Vitamin C (Ascorbate) levels. Administration of Ocimum sanctum extract (100 mg/kg body weight, po) and (200 mg/kg body weight, po) before and after cadmium intoxication showed a significant decrease in LPO levels and significant increase in SOD, CAT, GPx, GSH and Ascorbate levels. The results suggest that oral administration of Ocimum sanctum extract provides significant protection against cadmium induced toxicity in Wistar albino rats.  相似文献

School Teachers’ and Administrators’ Opinions about Disability Services,Quality of Schools,Total Quality Management and Quality Tools

ABSTRACT

The aim of this study is to determine primary school administrators’ and teachers’ opinions about the quality of their schools; the school administrators and teachers’ knowledge about Total Quality Management and quality tools and the quality tools used in primary schools. The research has been carried out with a qualitative approach and it is in the case study pattern. The participants consisted of 16 teachers and 4 school administrators working in primary schools in North Cyprus. The participants were chosen via maximum sampling method. The findings show that the current situation in schools contradicts with the basic principles of Total Quality Management. It was determined that school administrators were ignorant about Total Quality Management and none of the teachers and school administrators had previously heard the concept of quality tools. Teachers and school administrators mentioned disabled students as an issue. It seems like teachers have problems in behaving in the right way towards these students. They do not know how to improve these students’ talents because they are not educated on the subject. Via tools of quality teachers and school administrators may find reasons and solutions for issues like people with disabilities and plan events to promote disability awareness.  相似文献   

A botanist,mycorrhiza and a knighthood     

Ramesh Maheshwari 《Resonance》2008,13(6):541-547

Most plants are attached via their roots to specialized fungi. The filamentous hyphae of these fungi extend beyond the nutrient-depleted zone in the soil, absorbing and supplying nutrients to the plants in exchange for photosynthetically-made carbon compounds manufactured by the plant. The hyphae also attach to litter and decompose the organic matter, releasing the mineral ions sequestered in the structural polymers. The mineral ions are absorbed and translocated to the roots. Most plants are so dependent on their fungal partners for supplying nutrients that they languish or die without them. Our understanding of this fascinating interaction, to a large extent, has come from the pioneering work of Sir David J Read, FRS, Emeritus Professor of Plant Sciences at the University of Sheffield, UK. Ramesh Maheshwari is a former Professor and Chairman of the Department of Biochemistry, Indian Institute of Science, Banglaore. This is his sixth article for Resonance.  相似文献

If the content of this book is likely to be relevant to you, you should arrange to borrow a copy for a while. Ramesh Sharma  相似文献   

Life at high temperatures     

Ramesh Maheshwari 《Resonance》2005,10(9):23-36

Amazing microorganisms thrive at high temperatures incompatible with the familiar forms of life. A few species from hot springs or from the vicinity of hydrothermal vents at the floor of the oceans are the basis of a multimillion dollar industry. An entirely new form of animal life has been discovered around the volcanic eruptions from the sea floor. This animal life thrives in the permanently dark environment only because it harbors symbiotic bacteria that synthesize food molecules from inorganic chemicals in the emissions. Thermophilic microorganisms are involved in composting and humification in terrestrial habitats.  相似文献
