Stimulation of pigment accumulation in Anabaena azollae strains: effect of light intensity and sugars.

The influence of high light intensity on the growth and pigment accumulating ability of Anabaena azollae was investigated. A. azollae responded positively to high light intensity (6 klx) and was further evaluated at higher intensities (10 and 15 klx), in the presence of glucose, sucrose and jaggery +/- DCMU. Significant enhancement in phycobiliproteins and carotenoids was observed in the sugar supplemented cultures at high light intensities. SDS-PAGE profiles of whole cell proteins revealed the presence of unique bands in such treatments. Sucrose supplementation induced a 30-90 % increase in carotenoids, phycocyanin and phycoerythrin content at 10 klx. Molecular analysis of the stimulatory and interactive role of sugars on pigment enhancement at high light intensity may aid in better exploitation of cyanobacteria as a source of pigments.

Development of alternative support system for viable count of cyanobacteria by most probable number method.

A technique was developed to evaluate alternative support systems to test tubes used in the standard most probable number technique, for simultaneous isolation and enumeration of cyanobacteria. Five different support systems were tested for their suitability in terms of accuracy, sensitivity, economics and ease of handling. PCR plates with 96 wells and carrying capacity of 300 microL per well were found to be most sensitive, besides being cost- and time-effective. This technique can also be useful for isolation of cyanobacteria, due to immobilization of colonies in the gel matrix and storage of samples at room temperature, without loss of viability for 5-6 weeks. This technique can help to process large sample size with ease--both for enumeration and isolation and can be extended for enumeration of other microorganisms from diverse sources.

Groin abscess: a vesico-cutaneous fistula to the groin. A rare complication of open prostatectomy.

In developed countries, open prostatectomy for benign disease is now reserved for large prostates. This is not the case in the developing world where Millin's prostatectomy continues to be an important procedure, perhaps due to lack of endoscopic technology and training. We report a case of vesico-cutaneous fistula as a late complication of open prostatectomy presenting as a groin mass. A review of the English language literature shows this to be the first case of its kind.

The Gene Ontology (GO) database and informatics resource.

The Gene Ontology (GO) project (http://www. geneontology.org/) provides structured, controlled vocabularies and classifications that cover several domains of molecular and cellular biology and are freely available for community use in the annotation of genes, gene products and sequences. Many model organism databases and genome annotation groups use the GO and contribute their annotation sets to the GO resource. The GO database integrates the vocabularies and contributed annotations and provides full access to this information in several formats. Members of the GO Consortium continually work collectively, involving outside experts as needed, to expand and update the GO vocabularies. The GO Web resource also provides access to extensive documentation about the GO project and links to applications that use GO data for functional analyses.

Spontaneous pneumothorax: use of aspiration and outcomes of management by respiratory and general physicians.

BACKGROUND: Spontaneous pneumothorax is a common problem in hospital practice. Despite the publication of guidelines controversy over its initial management still exists, particularly over the use of simple aspiration. METHODS: The management of spontaneous pneumothorax by respiratory and general physicians at our hospital was analysed by retrospective case note review. Eighty five patients were identified over the study period (36 managed by respiratory and 49 by general physicians). RESULTS: There was a significantly greater use of simple aspiration by respiratory (81%) than general physicians (47%, p<0.001) and a higher rate of success in this group. As a result those patients managed by respiratory physicians had fewer intercostal drains inserted and significantly shorter length of stays (mean 5.6 (3.8) days respiratory group and 9.5 (6.8) days in general physicians group, p<0.05). CONCLUSIONS: The greater and more successful use of simple aspiration by respiratory physicians as an initial treatment for spontaneous pneumothorax resulted in improved outcomes and reduced length of hospital stays.

Plasma fibrinogen levels in stroke.

Plasma fibrinogen levels were estimated in 56 patients of stroke, admitted in the hospital within 24 hours of symptoms. The levels were found to be raised significantly (531.73 +/- 74 mg%) compared to those of the age and sex matched control group (445.78 +/- 92.28 mg%). When the levels in stroke group with one risk factor were compared to those of individuals with comparable control group with same risk factor, a significant difference was observed in hypertensive, smokers, alcoholics and atherosclerotic stroke groups, which indicates that the observed rise is related to phenomenon of stroke rather than the associated risk factors. However, the rise observed in hypertensive stroke group (554.26 +/- 47.08 mg%) is significantly more (p. less than 0.01) than that occurring for nonhypertensive stroke group (497.82 +/- 93.12 mg%) indicating that the presence of hypertension does contribute to the rise.
