Baseline data available on the excretory profiles of estrone giucuronide (E1G), pregnanediol glucuronide (PdG) and luteinising hormone (LH) on human menstrual cycles (n=104) was retrospectively analysed
for identifying the limits of fertile period (FP) to be used as natural method of family planning. The limits of fertile period
are suggested based on centile distribution of E1G and PdG levels during defined phase of menstrual cycle. Two approaches, which do not involve any mathematical calculation
are suggested. In approach A, fertile period is said to have started when E1G value of 35 ng/ml is reached and is said to have ended when the PdG value of 2 μg/ml on two consecutive days is obtained.
The criteria were applied to 30 test cycles in whom authentic fertile period was identified based on excretory profiles of
E1G, PdG and LH throughout the menstrual cycles. When approach A was followed the authentic fertile period was covered in 27
cycles giving an accuracy of 90% with a mean fertile period length of 9.11+1.9 days. In approach B, the cut off limit of E1G value was increased to 55 ng/ml in order to reduce the days of abstinence. Though the length of the fertile period was reduced
to 7.2+1.5 days the accuracy of the approach was 66.6%. Thus the approach A which has accuracy of 90% may appeal to determined
couples who wish to practice family planning by periodic abstinence or restrict the use of barrier methods. 相似文献

Uganda is recognised as an early success story in the HIV epidemic at least in part due to an open and vigorous national dialogue about HIV prevention. This study examined the national discourse about HIV, AIDS, and young people in New Vision, Uganda's leading national newspaper between 1996 and 2011, building from a previous archival analysis of New Vision reporting by Kirby (1986–1995). We examined the continuing evolution in the public discourse in Uganda, focusing on reporting about young people. An increase in reporting on HIV and AIDS occurred after 2003, as antiretroviral treatment was becoming available. While the emphasis in newspaper reporting about adults and the population at large evolved to reflect the development of new HIV treatment and prevention methods, the majority of the articles focused on young people did not change. Articles about young people continued to emphasise HIV acquisition due to early and premarital sexual activity and the need for social support services for children affected by HIV and AIDS. Articles often did not report on the complex social conditions that shape HIV-related risk among young people, or address young people who are sexually active, married, and/or HIV-infected. With HIV prevalence now increasing among young people and adults in Uganda, greater attention to HIV prevention is needed. 相似文献

As antioxidants play a protective role in the pathophysiology of diabetes and cardiovascular diseases, understanding the physiological
status of antioxidant concentration among people at high risk for developing these conditions, such as Metabolic Syndrome,
is of interest. In present study out of 187 first degree non-diabetic relatives and 192 non-diabetic spouses, 33.1% and 19.7%
were found to have metabolic syndrome respectively. Subjects with metabolic syndrome (≥3 risk factors) had poor antioxidants
status as reflected by significantly low levels of vitamin A, C & E and significantly increased (p<0.01) oxidative stress
as compared to those without metabolic syndrome. At the same time serum insulin levels and insulin resistance were found to
be significantly high (p<0.001) in metabolic syndrome. A strong positive correlation (r=0.946; p<0.001) between oxidative
stress and insulin resistance was observed in metabolic syndrome. Low levels of antioxidants and increased oxidative stress
with insulin resistance in metabolic syndrome suggests that besides therapeutic life style changes (TLC) as suggested in ATP
III guidelines inclusion of antioxidant vitamins, fruits and vegetable could be beneficial to ward off the consequences of
metabolic syndrome. 相似文献

The present paper focuses on assessing the levels of various enzymatic and non-enzymatic antioxidants in selected berries
of Indian sub-continent viz., gooseberry, grapes, orange and tomato. This study has revealed that orange, tomato and grapes
possess predominant quantities of enzymatic antioxidants namely SOD, catalase and glutathione peroxidase respectively. The
levels of antioxidants analyzed namely reduced glutathione, vitamin C and vitamin A were maximal in grapes, orange and tomato
respectively. All the extracts of berries included in the present study inhibited iron inducedin vitro lipid peroxidation in erythrocytes, the extend of inhibition being highest for gooseberry and orange compared to tomato and
grapes which could be attributed to their in-built antioxidant system. 相似文献

This study was undertaken to evaluate the role of serum neuron specific enolase (NSE) in prediction of disability and neurological worsening in hypertensive ischemic cerebrovascular stroke. 80 hypertensive ischemic stroke patients diagnosed by a neurologist as per WHO definition along with radiological findings suggestive of cerebrovascular stroke and differentiating from hemorrhagic stroke and 60 controls having essential hypertension coming to hospital because of regular checkup or headache but with no neurological disease were included in the study. Neurological disability was assessed by NIHSS at the time of admission (within 72 h from the onset of stroke) and on 7th day after admission and cases were categorized into mild, moderate and severe disability. Venous blood samples were drawn within 72 h from the onset of symptoms. The samples were processed as per the laboratory protocol. The serum NSE samples were analyzed using an enzyme immunoassay based on the sandwich technique. We observed raised serum NSE in hypertensive ischemic stroke (17.4 ± 5.4 ng/ml) with significant association between different hypertensive groups than in hypertensive controls (9.1 ± 0.75 ng/ml). Greater degree of disability was observed in hypertensive stroke patients with raised serum NSE and hypertensive patients with mean serum NSE level of 22.9 ± 3.6 ng/ml and dyslipidemia had greater probability of neurological worsening as compared to those with mean serum NSE level of 12.7 ± 1.2 ng/ml. Serum NSE levels can serve as a peripheral indicator of neuronal damage and assist in the prediction of disability and clinical outcome in hypertensive cerebrovascular ischemic stroke patients. 相似文献

Silver is ingested in India in the form of varak, Ayurvedic bhasm and water contained in silver utensils, but nobody knows
their effects. We have examined the effect of interaction of silver ingested in the form of varak (leaf), bhasm (ash) and
water (colloidal solution) on some essential elements (Na, K, Ca, Mg, Cu, Fe and Zn) in blood, liver, spleen and kidneys of
chicks. The results showed significant rise of silver in all the tissues and significant fall in copper in the blood. The
greatest rise was obtained in blood silver by silver sol while it had the lowest amount of silver. Iron significantly increased
in tissues but somewhat decreased in blood. Zinc content increased in all the tissues by leaf and ash but decreased by sol.
No consistent pattern was seen in case of other elements. 相似文献

The process of reflective writing can play a central role in making meaning as learners process new information and connect
it to prior knowledge. An examination of the written discourse can therefore be revealing of learners’ cognitive understanding
and affective (beliefs, feelings, motivation to learn) responses to concepts. Despite reflective writing being an important
learning tool, the role of this genre in upper-division college biology courses has not been well studied. This paper examines
how nineteen physiological ecology students wrote about their understanding of natural selection and adaptations in ten reflective
essays and describes how a model of student meaning making was developed. Qualitative essay analysis (through a triangulation
of data: class observations; essays; and transcribed interviews) revealed that students could be classified into four categories
of writers: subjective (personal, affective connections); objective (conceptual, cognitive connections); authentic (both affective and cognitive connections); and superficial (no supportive connections or claims). In-depth case studies illustrating these four categories are presented. Implications
for college science instruction are discussed. 相似文献

The application of ICT solutions for the development of rural India and other developing countries opens up a vast range of possibilities. Giving an opportunity to the vast majority of the population living in rural areas, to cross the digital divide to obtain access to information resources and services provided by ICT is the next revolution waiting to happen. Although this is a development issue, it is just not the government, non-government organizations or the rural masses that have a role to play. Private profit-making institutions can develop solutions to capture the hitherto unrecognized markets, make profits and at the same time aid the rural societies. The new technologies being developed can help surmount barriers present in providing information resources at a low cost and make applications feasible and profitable. This paper presents some cases where ICT has been effectively used for the benefit of the rural societies and analyzes the opportunities that lie in this sphere. The cases range from successful use of ICT in governance, to ICT solutions for improved profits to ICT in microfinance. A case of an initiative by a large mainstream corporation to reach out to the rural sector, help in development and realize profits mutually is also presented. The projects discussed should generate more interest and facilitate private investment in the hitherto virgin territory. A large number of hurdles still remain but creative ideas, breakthrough ICT technologies and committed organizations can usher in the next revolution in the developing world. 相似文献

A very useful experiment of two dimensional potential mapping, namely electrolytic tank model, for graduate and post graduate
level physics students is given here. Laplace's equation is solved for the above and the results are compared with the experiment.
The agreement is so good that this is extended to complex problems. Monte Carlo simulation, an alternative to the above experiment,
is developed for these complex problems and compared with the experimental results of electrolytic tank model. 相似文献

Conceptual change in undergraduate capstone courses provides unique opportunities to examine how students draw from multiple courses and experiences to resolve conceptual confusion. We examined how senior-level natural resource management students revised their conceptions of ‘ecosystem’ throughout their capstone course. The concept of ecosystem is complicated by a lack of shared meaning across disciplines. Our grounded theory study analyzed student coursework and pre/post interviews. It was informed by socio-cultural and conceptual change theories and used an ecological literacy metric to examine how students’ conceptualizations of the relationships between natural, ecosystem, human, and human artifact influenced their conceptions of ecosystems. Students who did not describe ecosystems as natural struggled less with integrating human society into ecosystems than their peers that did. We conclude that it is important to explicitly create shared meaning of key conceptions at the start of a capstone course to facilitate shared meaning-making and desired conceptual change during the course. 相似文献
