Evaluation of oxidative stress, antioxidants and prolactin in infertile women     

Bhaskar S Veena  Sharmila Upadhya  Satish Kumar Adiga  Kumar N Pratap 《Indian journal of clinical biochemistry : IJCB》2008,23(2):186-190

The objective of the study was to estimate the serum concentrations of oxidative stress markers-lipid hydroperoxide (MDA-Malondialdehyde), lactate dehydrogenase (LDH), nitrite; and ferric reducing antioxidant power (FRAP) — a measure of total antioxidant capacity in serum. Serum nitrite levels were high in fertile women than in infertile women (p<0.001), whereas MDA was high in infertile women than in fertile group (p<0.018). On classifying the entire group of women with infertility based on the etiology, serum MDA and LDH levels were higher in women with infertility due to unexplained factor than in women with other causes contributing to infertility compared to controls (p<0.001, p<0.02). A positive correlation among serum prolactin and nitrite suggested that hyperprolactinemia could contribute to infertility by inducing oxidative damage. Serum FRAP levels showed no significant difference in the groups studied. Lipid peroxidation was high in women with unexplained infertility which may be due to hyperprolactinemia.  相似文献   

Interferences in clinical chemistry analysis     

K. S. S. Saibaba  M. Vijaya Bhaskar  P. V. L. N. Srinivasa Rao  G. V. Ramana  K. V. Dakshinamurty 《Indian journal of clinical biochemistry : IJCB》1998,13(2):55-62

Analyses of body fluids in clinical chemistry laboratory are subject to a number of interferences that affect the analytical accuracy. The interferents arise from exogenous sources like drugs and additives as well as such endogenous sources like lipemia, hemolysis and icteria. Our studies demonstrate matrix interference in the form of analytical blas between serum and aqueous matrix calibrators. The clinical chemist should constantly be aware of this factor. Correction of interferences is recommended as an integral part of the quality assurance program.  相似文献

Serodiagnosis of tuberculosis using two ELISA systems     

Swati Banerjee  Sonika Gupta  Niraj Shende  Satish Kumar  Bhaskar C. Harinath 《Indian journal of clinical biochemistry : IJCB》2003,18(2):48-53

Serodiagnosis by ELISA has been widely explored over the years, in the diagnosis of tuberculosis. Two ELISA systems were evaluated for detection of mycobacterial antibodies in pulmonary and extra pulmonary tuberculosis. The two test assays explored were ERBA LISA (TB IgG) test (Anda Biologicals) which uses A60 antigen complex found in the cytosol of typical and atypical mycobacteria, and SEVA TB (IgG) ELISA, which uses a 31 kDa, glycoprotein antigen purified fromM. tb H₃₇Ra culture filtrate. Sera from 98 proven tuberculosis [pulmonary TB (48), tuberculous lymphadenopathy (30), tuberculous meningitis (15) & genitourinary TB (5)] were studied along with 32 healthy controls. The overall positivity obtained using ERBA LISA (TB IgG) test and SEVA TB (IgG) ELISA test was 72.9% and 91.6% in pulmonary tuberculosis, 43.3% and 76.6% in tuberculous lymphadenopathy respectively. The sensitivity of ERBA LISA test in tuberculous meningitis and genito-urinary TB was significantly low (26.6% & 40% respectively) compared to sensitivity obtained using SEVA TB ELISA (86.6% & 60% respectively) with overall specificity of 60% and 87.5%. Thus SEVA TB IgG ELISA test was found to be more sensitive than ERBA LISA in detecting IgG antibodies in tuberculous sera, in particular in extra pulmonary tuberculosis cases.  相似文献   

Salivary Alpha Amylase Activity in Human Beings of Different Age Groups Subjected to Psychological Stress     

Gopal K. Sahu  Seema Upadhyay  Shradha M. Panna 《Indian journal of clinical biochemistry : IJCB》2014,29(4):485-490

Salivary alpha-amylase (sAA) has been proposed as a sensitive non-invasive biomarker for stress-induced changes in the body that reflect the activity of the sympathetic nervous system. Though several experiments have been conducted to determine the validity of this salivary component as a reliable stress marker in human subjects, the effect of stress induced changes on sAA level in different age groups is least studied. This article reports the activity of sAA in human subjects of different age groups subjected to psychological stress induced through stressful video clip. Differences in sAA level based on sex of different age groups under stress have also been studied. A total of 112 subjects consisting of both the male and female subjects, divided into two groups on basis of age were viewed a video clip of corneal transplant surgery as stressor. Activity of sAA from saliva samples of the stressed subjects were measured and compared with the activity of the samples collected from the subjects before viewing the clip. The age ranges of subjects were 18–25 and 40–60 years. The sAA level increased significantly in both the groups after viewing the stressful video. The increase was more pronounced in the younger subjects. The level of sAA was comparatively more in males than females in the respective groups. No significant change in sAA activity was observed after viewing the soothed video clip. Significant increase of sAA level in response to psychological stress suggests that it might act as a reliable sympathetic activity biochemical marker in different stages of human beings.  相似文献   

Celebrating Jhumki Basu’s contributions to science education as a scholar and an activist: voices from the field     

Catherine Milne  Laurie Rubel  Alberto J. Rodriguez  Christopher Emdin  Maria Rivera Maulucci  Donyagay Locke  Edna Tan  Neil Clairmont  Bhaskar Upadhyay 《Cultural Studies of Science Education》2009,4(2):399-407

This metalogue addresses the ways Sreyashi Jhumki Basu mediated our practices in science education and life. We focus on Basu’s uses of critical science agency, democratic science classrooms, and critical feminist ethnography to transform the possibilities for all participants in her research and educational practices. We also examine her use of cases and pedagogical strategies to support youth set practice goals based on conceptions of self and preferred learning trajectories. These strategies allow youth to develop power through the use of disciplinary knowledge and modes of inquiry to support their understanding of themselves as powerful, able to change their position in the world, and make the world more socially just. This (Key Contributors) article acknowledges a life cut short through disease, reflects our personal loss of a friend and colleague, and expresses determination to ensure that her contributions to science education are sustained and continued.

Photodynamic Therapy (PDT)     

Bhaskar G. Maiya 《Resonance》2000,5(4):6-18

Photodynamic Therapy (PDT) is a newly emerging modality against cancer in which a photosensitizing molecule acts against malignant tumors under the influence of light. An overview of the chemical, photochemical and biochemical basis of PDT is presented in this series of articles. In doing so, an attempt has been made to illustrate how a topic such as PDT —which is related to human health —can generate interest amongst students in interdisciplinary areas bordering between chemistry and biology. Besides providing a general introduction to PDT, details of the physical and biochemical mechanisms of photodynamic action are provided in this article.  相似文献   

The hyperlinking pattern of open-access journals in library and information science: A cited citing reference study     

Bhaskar Mukherjee 《Library & information science research》2009

Using 17 open-access journals published without interruption between 2000 and 2004 in the field of library and information science, this study compares the pattern of cited/citing hyperlinked references of Web-based scholarly electronic articles under various citation ranges in terms of language, file format, source and top-level domain. While the patterns of cited references were manually examined by counting the live hyperlinked-cited references, the patterns of citing references were examined by using the cited by tag in Google Scholar. The analysis indicates that although language, top-level domain, and file format of citations did not differ significantly for articles under different citation ranges, sources of citation differed significantly for articles in different citation ranges. Articles with fewer citations mostly cite less-scholarly sources such as Web pages, whereas articles with a higher number of citations mostly cite scholarly sources such as journal articles, etc. The findings suggest that 8 out of 17 OA journals in LIS have significant research impact in the scholarly communication process.  相似文献
