We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20–80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = − 0.4, p < 0.0001), and showed an increasing trend with age. We have thus presented metabolic bone profile of healthy, adult north Indian population. These reference values can be used for diagnosis and monitoring of various MBDs. Vitamin D deficiency is still rampant in our population in spite of increasing awareness. 相似文献

The circadian periodicity of plasma lipid peroxide levels and activities of superoxide dismutase (SOD), catalase (CAT) and
glutathione peroxidase (GPx) were studied in 50 clinically, bacteriologically and radiologically proven fresh cases of pulmonary
tuberculosis (age: 21–45 years) and 60 age-matched healthy volunteers with diurnal activity from 06∶00 to about 22∶00 and
nocturnal rest. A marked circadian variation in plasma lipid peroxide level was recorded in healthy subjects and pulmonary
tuberculosis patients with significant amplitude and acrophase around 16∶21 and 17∶12 respectively. The acrophase tended to
be delayed in tuberculosis patients. Furthermore, a statistically significant circadian rhythm was found in SOD, CAT and GPx
activities in normal volunteers and pulmonary tuberculopsis patients. SOD and CAT enzyme activity was noted to be maximum
at 06∶00 and minimum at 00∶00 in tuberculosis patients. The circadian acrophase for GPx activity was recorded at 16∶15 in
normals and around 22∶45 in patients. Moreover, the activity was found to be decreased at all sampling hours during 24-hours
sleep-awake period in patients in comparison to healthy counterparts. The MESOR and circadian amplitude also decreased markedly.
The decreased activity of measured antioxidant enzymes in pulmonary tuberculosis patients could probably be associated with
oxidative stress and/or decreased anti-oxidant defensive mechanism in such patients. 相似文献

Curriculum reform is a key topic in the engineering education literature, but much of this discussion proceeds with little engagement with the impact of the local context in which the programme resides. This article thus seeks to understand the influence of local contextual dynamics on curriculum reform in engineering education. The empirical study is a comparative analysis of the context for curriculum reform in three different chemical engineering departments on the African continent, located in Kenya, Tanzania and South Africa. All three departments are currently engaged in processes of curriculum reform, but the analysis shows how the different contexts in which these efforts are taking place exert strong shaping effects on the processes and outcomes for that reform. 相似文献

G N Ramachandran made several remarkable contributions to biophysics and structural biology over the course of his celebrated career. In a pair of seminal papers in 1971, he also laid the foundation for the technique of ‘Projection Reconstruction’ that has come to revolutionize medical imaging. It is now routinely employed in modern CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans. In this article, we review the salient features of this technique, that allows the ‘reconstruction of an object from its shadows’. 相似文献

‘Postage stamps’, basically as a token for payment of postal taxes, are now being recognized as an information source and historical document in recording national achievements that visually convey four core elements: denomination, country name, graphical design, and the textual element. They are a valuable means of communication easily available anywhere to anybody. Realizing them as source of extra revenue, commemorative stamps are made available over time. The information technology (IT) wave changed the hobby of stamp collection to Digital Philately, while information and communication technology (ICT) developments accelerated the hobby further to Virtual Philately.This paper focuses on the aspects of digital and virtual philately. This study aims to evaluate The World Association for the Development of Philately (WADP) Numbering System (WNS) database, which provides free access to authentic postage stamps issued by Universal Postal Union (UPU) member countries and territories. A total of 48,159 stamps with 48 themes were found registered by 184 countries at the time of study. Indian stamps totaled 554 entries with the highest number of entries, 1258, from France, and followed by 1006 from Japan. A ranking was done using themes whereas “Fauna” was observed to be the most popular theme at 14.1% or 6800 stamps under study. For Indian stamps, politics and government, architecture and literature, press and comics are the most prevalent themes with 14.3, 9.8 and 9.8% respectively of the national contribution. The paper also presents a detailed analysis of the 15 Indian stamps commemorating the 14 Indian traditional universities issued over the 50 years of India’s independence. 相似文献
