In vitro grown callus and seedlings of Brassica juncea were treated with equimolar concentrations of cadmium and compared for their respective tolerance to cadmium. Calli cultures were grown on Murashige and Skoog medium supplemented with alpha 6-benzyl aminopurine (200 microg (-1), naphthalene acetic acid 200 microg L(-1)) and 2,4-dichloro-phenoxy acetic(More)
Haem oxygenase (HO) degrades free haem released from haem proteins with the generation of ferrous iron (Fe2+), biliverdin-IXalpha (BV-IXalpha), and carbon monoxide (CO). The mechanism of haem cleavage has been conserved between plants and other organisms even though the function, subcellular localization, and cofactor requirements of HO differ(More)
Two auxiliary nurse midwives (ANMs) were recruited and trained to recognize normal and different types of abnormal cervices. A total of 2102 women were examined by a gynaecologist and ANM independently and their findings were noted. Comparison of their findings showed an overall agreement of 89.6 per cent (Kappa 0.84 with standard error of 0.015 and a(More)
Fine needle aspirates (FNA) were obtained from lymph node and other sites in 250 suspected cases of tuberculosis. Twenty-four cases proved to be non-tubercular on FNA smears and served as negative controls. Of the smears obtained from the remaining 226 cases, 233 were classified into five groups based on cytomorphological features, i.e. presence of necrosis(More)
This hospital-based study in New Delhi, North India was performed to evaluate the prevalence of human papillomavirus (HPV) in cases of invasive cervical carcinoma (ICC). A total of 10 cases presenting with an obvious cervical growth were included in this study. 108 cases that was shown to be ICC on histology (101 squamous cell carcinomas, 4 adenocarcinomas,(More)
BACKGROUND Helicobacter pylori is an etiological factor in duodenal ulcer. Few studies have objectively assessed the accuracy of diagnostic methods for the detection of H. pylori. METHODS The sensitivity and specificity of histology, touch smear, rapid urease test (RUT) and brush cytology of endoscopic antral biopsy from patients with duodenal ulcer were(More)
Laboratory grown duckweed (Spirodela polyrhiza) plants were exposed to 0.72 and 1.44J of UV-B radiation daily for 7 days at 0.4mW/cm(2) intensity. Chlorosis and necrosis were observed along with depletion in protein, pigments (chlorophyll, pheophytin, carotenoids, phycoerythrin, phycocyanin, and flavoxanthin), biomass, root length, and frond size in(More)
Metabolic adaptations to heavy metal toxicity in plants are thought to be related with developmental growth stage and the type of metal by which plant is affected. In the present study, changes in ionically bound CWP, soluble peroxidase activity, H(2)O(2) level and Malonaldehyde content in roots of cadmium and copper stressed seedlings and cadmium stressed(More)
Countrywide salt iodization, to prevent nutritional iodine deficiency, has been achieved in India recently. The current study was planned to evaluate the prevalence of goiter and thyroid autoimmunity and assess thyroid functional status in a cohort of 6283 healthy schoolgirls from different parts of the country in the postiodization phase. Goitrous girls (n(More)
Research on NO in plants has achieved huge attention in recent years mainly due to its function in plant growth and development under biotic and abiotic stresses. In the present study, we investigated Cd induced NO generation and its relationship to ROS and antioxidant regulation in Brassica juncea. Cd accumulated rapidly in roots and caused oxidative(More)
