The present study defines the systematic evaluation and the role of minerals in glycemic potential of aqueous extract of Withania
coagulans fruits in order to develop an effective and safe alternative treatment for diabetes mellitus. Laser Induced Breakdown
Spectroscopy was used for glycemic element detection. The study is based on the results of lowering in blood glucose levels
of normal, sub, mild and severely diabetic rats assessed during fasting blood glucose, glucose tolerance test and post prandial
glucose studies. The dose of 1000mg/ kg was identified as the most effective dose, which reduces the Fasting Blood Glucose
level maximum by 33.2% at 4h in normal rats during fasting blood glucose studies. Glucose tolerance test studies of normal,
sub and mild diabetic rats showed the maximum reduction of 15.7, 28.9 and 37.8% at 3h respectively. Long-term study in case
of severely diabetic rats showed reduction of 52.9 and 54.1% in Fasting Blood Glucose and Post Prandial Glucose levels respectively
after 30 days of treatment. The present study, besides confirming hypoglycemic and antidiabetic activities of aqueous extract
of W. coagulans, helps in identifying the role of trace minerals like Mg & Ca responsible for antidiabetic potential of this
potent indigenous shrub. 相似文献

The present study deals with the evaluation of glycemic profile of aqueous extract of Cajanus cajan leaves in streptozotocin induced type 2 diabetic rats. Single oral administration of graded doses of aqueous extract of Cajanus
cajan leaves showed significant increment of 14.3 % in fasting blood glucose levels of normal rats. The sub diabetic and mild diabetic
models have also shown hyperglycemic effect from the same variable doses of the extract. The dose of 1000 mg/kg showed the
maximum rise of 17.1, 71.2 and 50.7 % in Blood glucose levels of normal, sub and mild diabetic rats respectively during glucose
tolerance test. The study of leaves was taken into consideration on the basis of earlier reported hypoglycemic activity of
Cajanus cajan seeds. However the results observed were found just opposite and therefore it may be useful in controlling hypoglycemia,
occasionally caused due to excess of insulin and other hypoglycemic drugs. 相似文献

Biosensors function by coupling a biological sensing element with a detector system using a transducer. They are widely used
in diagnostics, pharmaceutical research, fermentation-based industries and environmental and pollution monitoring. 相似文献

Supramolecular chemistry as de-ned by Lehn ‘chemistry beyond the molecule’ focuses on the development of functional complex architectures through non-covalent interactions. The year 2017, marked the fiftieth anniversary of the serendipitous discovery of crown ethers. Since then, the field is growing, and due to the efforts of various researchers now it is possible to have some control over the arrangement of things on a small scale. In this review article, the concept of supramolecular chemistry, cooperativity responsible for interactions, techniques for determination of thermodynamic parameters of cooperativity, and the contribution of supramolecular chemistry to nanotechnology is described. 相似文献

This study confirms the fact that in different respiratory disorders, the status of plasma oxidants and antioxidants shifts
from normal. The status of oxidants in plasma as represented by malondialdehyde (MDA) levels increased significantly in the
conditions of chronic obstructive pulmonary disease (COPD), emphysema, bronchiectasis and bronchial asthma. The two vitamin
antioxidants vitamin C and vitamin E showed decreased levels than in controls. In patients with COPD the endogenous antioxidant
viz. reduced glutathione (GSH) estimated from whole blood was comparable to that of control group, whereas in patients with
emphysema, bronchiectasis and bronchial asthma, GSH concentration was increased to that of control group. The activity of
enzyme superoxide dismutase (SOD) was significantly decreased in all study groups. Pulmonary function tests were found to
have no correlation with MDA and antioxidants 相似文献

Summary In order to understand the mechanism of fauling of electrode surfaces ofin vivo electrochemical sensors used for monitoring whole blood, the investigations on protein adsorption on the membrane surfaces
were undertaken. Using an oxygen sensor, the protein adsorption studies were carried out on two different polymeric surfaces-teflon
(PTFE) and polyurethane (PU)-using Scanning Electron Microscopy and Fourier Transform Infrared Spectrophotometry. Investigations
reveal that even a single protein like albumin or fibrinogen tend to adhere to the sensor membrane surface and influences
the electrochemical characteristics of the sensor. The influence is more significant, in the case of PTFE membrane. 相似文献

This study examines the factors that shape calling orientations within the Indian context. Based on the narratives of 72 junior doctors and medical interns, it is found that participants identify with harbouring a calling both prior and subsequent to occupational entry. Although factors such as self-recognition of talent and sensemaking of work as destiny play a role, familial communication is found to be particularly influential in the formation of a calling outlook. A relational view of callings associated with generativity and family legacy is thus highlighted. The study additionally compares the career stories of individuals who do (n = 29) and those who do not (n = 43) frame their occupation as a calling. Participants with a calling orientation are found to have a strong affective attachment to the profession, further influenced by familial communication and value internalization. The findings also demonstrate that the calling experience is malleable and can evolve through work/life experiences. 相似文献
