The incidence of prostate cancer (PCa) in India is shown to have increased with increasing life-expectancy, use of diagnostic marker like prostate specific antigen (PSA) and changing life style. Prostate cancer occurs at an old age with peak incidence occurring after 65 years of age. Since PCa is often asymptomatic, screening for prostate cancer is essential for an early diagnosis in men above 55 years of age. PSA is the most widely used biomarker for the early diagnosis of PCa. However, the use of PSA as a screening tool for the early diagnosis of PCa has been controversial. The use of PSA combined with Digital Rectal Examination (DRE) improves the possibility of diagnosis of PCa. Imaging techniques are much more used for staging of PCa and for guiding of needle biopsy. The present review describes various diagnostic modalitieswith its merits and demerits, whether used for the early diagnosis of PCa in an individual patient by urologist or used for population screening purposes.- Tide-Induced Geometrical Changes in Chilika Lagoon Using Remote Sensing

This article presents hourly data from four tide gauge locations in the Chilika lagoon vis-à-vis satellite data, to study the tidal influences on the geometrical changes in the lagoon. The satellite-derived highest area and perimeter are 864.76 km2 and 1512 km respectively, consistent with the field-observed occurrences of the low and high tides. The geometrical changes of 5.4% (44.36 km2) in area, and 24.8% (300.83 km) in the perimeter, in one month duration, solely because of the tides are considerable changes. High radiometric resolution of the sensor provided improved delineation of land-water boundary of the lagoon shores.Keywords

Mg-Sn alloys contain thermally stable Mg2Sn phase, and are proposed as heat-resistant alloys for automobile engine applications. In this study, the creep behaviour of Mg-5Sn alloy was investigated using impression creep technique. The impression creep tests were carried out under constant punching stress in the range of 80-320 MPa at temperatures 373-573 K, for dwell times up to 5 hours. The results highlight that creep of Mg-5Sn alloy was load and temperature dependent, i.e. increasing the load and temperature resulted in larger creep deformation and hence to higher creep rates. From the creep curves, the stress exponent and the activation energy were estimated and the creep mechanism was identified.Keywords

Rationale: To study the correlation between the sputum bacteriology and lung function in patients with stable bronchiectasis.
Materials and Methods: 80 patients suffering from stable bronchiectasis belonging to both the sexes and age above 14 years were included in study. All patients were assessed clinically with detailed history and thorough clinical examination. Patients were subjected to assessment of microbiological flora in their sputum. Lung functions were measured with spirometry and parameters recorded were PEFR in l/min, FEV1 in litres, FVC in litres, and FEV1/FVC. Sputum samples of +1 and +2 grade were inoculated on blood agar, MacConkey's agar and chocolate agar at 37°C for 48 hours.
Results: P aeruginosa was seen as the most common colonizing bacteria and these patients had de-creased % predicted FEV1, FVC, FEV1/FVC and PEFR with mean values of 43.61±14.6, 51.87±16.8, 79.83±14.6, 42.17±14.6 respectively as compared to patients of non P aeruginosa group. The % predicted FEV1, FVC, FEV1/FVC and PEFR in non P aeruginosa group were 47.67±21.8, 59.32±22.8, 81.89±17.7, 49.58±21.7 respectively. Though the values of FEV1, FVC, FEV1/FVC and PEFR in P aeruginosa group were decreased they were not statistically significant.
Conclusion: P aeruginosa was the main colonizing bacteria especially in patients having air fluid levels on radiology which can also be a predictor of bacterial colonization. Lung functions were de-creased in patients having P Aeruginosa in their sputum as compared to non P Aeruginosa group but they were statistically not significant.

The ultrasonic velocity, density and viscosity of binary mixtures of 2-butoxyethanol with PEG200 and PEG 400 were measured at 293, 303 and 313 K over the entire range of composition. Using these experimental data, various thermo-acoustic parameters such as deviation in isentropic compressibility (Δks), excess molar isentropic compressibility (KEs), excess molar volume (VEm) , and molar refractive deviation (ΔRm) have been calculated and fitted to Redlich-Kister polynomial equation. The deviation / excess parameter were plotted against the mole fraction of 2- butoxyethanol over the whole composition range. The values of (ΔKs), (VEm) and (ΔRm) are found to be negative and constantly become more negative for mixtures with PEG 400 independently of the solvents. The partial molar isentropic compressibility and excess partial molar isentropic compressibility at infinite dilution have been evaluated. The results of partial molar isentropic compressibility at infinite dilution supports the presence of strong intermolecular interactions between unlike molecules and more pronounced interaction in the mixture of 2-butoxyethanol with PEG 400. The results of density, ultrasonic velocity and refractive index measurement were also fitted to a second order polynomial equation with respect to mole fraction of 2-butoxyethanol.Keywords
