Implications of Secondary Treated Distillery Effluent Irrigation on Soil Cellulase and Urease Activities  [PDF]
Devendra Mani Tripathi, Smriti Tripathi, B. D. Tripathi
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.25075
Abstract: Currently distillery effluents have attracted worldwide attention for their application in agricultural land. The present investigation deals with the effect of application of various dosages of distillery effluent irrigation on soil physicochemical, Cellulase and Urease activities in a tropical agricultural field. Experiment was designed in factorial model by using randomized block design. Soil cores were sampled from the selected pits of both polluted and non polluted (control) sites. Majority of soil physicochemical properties (e.g. silt, clay, electrical conductivity, organic matter, total nitrogen contents, cellulase and urease activities) were significantly higher in the samples from polluted site than the non polluted site just after 15 to 30 days of incubation. Although application of effluents at lower rate substantially increased the enzyme activities, the same decreased at high effluent concentration. Prolonged incubation period resulted in gradual suppression of enzyme activity in both polluted and nonpolluted soil samples. Thus, the present investigation suggest that with the passage of time substrate for enzyme activity decreases which in association with residual toxicity resulted in the reduced enzyme activity.
Lactating Mother and Psychotropic Drugs
Tripathi B,Majumder Pradipta
Mens Sana Monographs , 2010,
Abstract: Usage of psychotropics during pregnancy and lactation has always been a topic of debate and controversy. The debate stems from the potential adverse effects on the growing fetus or infants due to the transfer of psychotropic drugs through placenta or breast milk of mothers receiving them; and the problem of discontinuing psychotropics in lactating mother considering chances of relapse. However, most of the psychotropics are found to be relatively safe when used cautiously during the lactation phase. This article describes available data on the use of psychotropics in lactating mothers, in particular, in relation to the safety profile of infants.

Nidhi Pandey, Yamini B Tripathi
Journal of Inflammation , 2010, DOI: 10.1186/1476-9255-7-47
Abstract: In recent years, phyto-medicine is in great demand as food supplement for age related chronic diseases, because of their multi-targeted action and lesser side effects [1] In fact, these diseases are associated with generation of excessive free radical (FR) [2] and associated inflammation [3] and these herbal products are rich in polyphenols, specially flavones and tannins. Therefore, search for potent antioxidants with anti-inflammatory potential has always been in demand. In various countries, these herbs are used as a component of their alternative system of medicine [4] and in Ayurveda, an Indian system of medicine, medicinal plants are well documented for their therapeutic claims, with records of long clinical use, for prevention and management of several metabolic disorders [5].Pueraria tuberosa Linn (PT), Leguminosae (Fabaceae), known as Bidaarikand [6] is an extensive perennial climber, with palmately arranged leaves, blue colored flowers and half inches thick bark [7], growing throughout tropical parts of India, mostly in moist regions, monsoon forests and coastal tracts. Its tuberous root, which is brown in color and slightly curved, is in clinical use for rejuvenation therapy. Its microscopic picture reveals the presence of prismatic calcium crystals and tanniniferous cells. It's major chemical constituents include flavones [C-glycoside (5,7,3',5'-tetrahydroxy-4'-methoxyflavone-3'-O-α-Lrhamnopyranosyl1→3-O-β-D-galactopyranoside)], Isoflavones (Puerarone), Coumstan (Tuberostan, Puerarostan) [8], Epoxychalcanol [Puetuberosanol], (3'-hydroxy-4'-phenoxy-α,β-epoxychalcan-α'ol)] [9], Pterocarpanoids [Hydroxytuberosin, Anhydroxytuberosin (3-O-methylanhydrotuberosin)] [10], and Tuberosin [11]. The powder of PT root-tubers are in clinical use as anti-aging and also as tonic, aphrodisiac, demulcent, lactagogue, purgative, cholagogue and also in scorpion sting. Besides, it is also useful in emaciation of children, debility and poor digestion [6,7]. Other investigator
IN-VITRO OCCLUSION STUDIES OF SOLID LIPID NANOPARTICLES LOADED HYDROGEL BY WATER VAPOUR PERMEABILITY ANALYSIS
G. Tripathi,B.K. Dubey
Journal of Global Pharma Technology , 2011, DOI: 10.1234/jgpt.v3i4.373
Abstract: Solid lipid nanoparticles (SLN) offer sustained release of drug into skin and work as drug depot within epidermal space. This inherent property is greatly employed for topical application of several drugs. Skin penetration of various drugs as well as cosmetic products depends upon skin hydration. Trans-epidermal water loss causes drying of skin thereby making stratum corneum more impermeable to most topical drugs. Solid lipid nanoparticles being smaller in size offer less inter-particles space for water evaporation. It is therefore necessary to evaluate its occlusive effect by some parameters. In the present study we prepared dithranol loaded solid lipid nanoparticles by using tristearin as lipid matrix. In-vitro occlusive studies were performed using water-vapour permeability evaluation. Method is simple and economic. Studies revealed that SLN reduced 14.89 % trans-epidermal water loss when compared to normal formulations. Scanning electron microscopy and particle size distribution studies were also performed. Our method produced SLN having 332 nm sizes with very less polydispersity and good spherical shapes. It can therefore be concluded that SLN carrier can be an advantageous choice for topical drug application as well as cosmetics.

Journal of Engineering and Applied Sciences , 2010,
Abstract: This paper presents confirmation test and renovation of 4x9 MW vertical Francis turbine of UMIAM hydro Power station situated at Shillong, Meghalaya State of India. For this purpose before renovation of plant, test conducted for measurement of various signatures like pressure, temperature, speed, vibration etc. which increase due to old age. The results show that after confirmation test and renovation the generator output is always improved for the parameters like guide vane servomotor stroke, vibration, shaft run out and noise at turbine pit entrance. The result also provides information that the overall efficiency of the plant is increased after renovation.
MEASUREMENTS OF RAIN DROP SIZE DISTRBUTION FROM RADAR REFLECTIVITY AND ASSOCIATED RAIN ATTENUATION OF RADIO WAVES
A. B. Bhattacharya,,D. K. Tripathi,,A. Nag,,M. Debnath
International Journal of Engineering Science and Technology , 2011,
Abstract: Radar measurements of rainfall at different climatological conditions have been taken into account emphasizing rain rate and associated radar reflectivity. It is observed from the analysis that thereflectivity measurement is being consistent at high rain intensities. From the knowledge of radar reflectivity, the rain drop size distribution is examined. The most probable drop size diameter and rain rate have been calculated wherefrom it appears that the most probable rain drop size vary exponentially with radar reflectivity and also with rain rate. The theoretical model implemented by using the measured rain drop sizes over the tropical sites also show similar kind of variation. For estimating rain attenuation two important parameters, viz., the point rainfall rates and the vertical and horizontal structures of rain have been considered. The elevation angle we have chosen is ~ 560 as most of the stations in India havethat value of elevation angle with geostationary satellite. Taking the frequencies 11 to 14 GHz separately and 00 C isotherm height as 5.0 km, the effective rain height values are determined. The attenuation of radio waves due to rain are calculated for different rain rates assigning different γ-values. The attenuation is found to vary significantly with the γ-values. Also the attenuation curves are closer when the γ-values are of low order. An increase in attenuation with the γ-values is found to be more prominent for higher rain rates.
Inverted papilloma of the urinary bladder: Rigorous surveillance needed? An Indian experience
Tiwari P,Tripathi A,Vijay M,Mitra B
Indian Journal of Cancer , 2010,
Abstract: Aims: Inverted papilloma (IP) is an uncommon benign neoplasm of the urinary tract. Its multiplicity, recurrence, and association with transitional cell carcinoma (TCC) leads to conflicting clinical conclusions regarding its biological behavior, and hence, the need for rigorous follow-up protocols. In this study, we review all cases of urinary bladder IP in our institution and determine the need for strict follow-up. Materials and Methods :0 We included consecutive patients from August 2004 to August 2008 with IP of the urinary bladder in this study who did not have prior or concurrent urothelial carcinoma. A single pathologist performed the histologic review. The patients had undergone strict a follow-up schedule every 6 months. Results: In our study of the 24 patients, the mean age at presentation was 53.5 (range 22-81) years. The mean follow-up period was 25.8 months (range 6-58 months). Of the 24 patients, 21 were men and 3 were women. No patient had a synchronous or previous bladder tumor. The most common presenting symptoms were macroscopic hematuria and dysuria. All were solitary tumors except one, most commonly found at the bladder neck and trigone. The average follow-up period was 2.5 years without any evidence of recurrence. Conclusions: We conclude that when diagnosed by strictly defined criteria, IP as benign urothelial neoplasm was with extremely low incidence of recurrence and good prognosis. It does not seem to be a risk factor for TCC, especially if located in the bladder. Therefore, a good transurethral resection is adequate therapy and follow-up protocol as rigorous as those for TCC may not be necessary.

Kumawat B,Sharma C,Tripathi Gautam,Ralot Tarun
Indian Journal of Medical Sciences , 2007,
Abstract: Wilson′s disease (WD) is a genetic neurodegenerative disorder; it exhibits wide heterogeneity in symptoms and usually presents with liver disease and/ or neuropsychiatric manifestations. The common neurological manifestations observed are dysarthria, gait disturbance, dystonia, rigidity, tremor, dysphagia and chorea. The frequent psychiatric manifestations reported are personality and mood changes, depression, phobias, cognitive impairment, psychosis, anxiety, compulsive and impulsive behavior. Isolated obsessive-compulsive disorder (OCD) is a rare presentation of WD. Reported herein is a case of a 17-year-old boy with isolated OCD. He presented to the psychiatrist with symptoms of contamination obsessions and washing compulsions, along with compulsion of repeated feet tapping, and was treated with adequate doses of fluoxetine for 6 months but did not improve. Later on, he was diagnosed as a case of WD and showed improvement with chelating and behavior therapy. This implies the importance of the occurrence of isolated psychological symptoms in WD.

Neurology India , 2009,
Abstract: Penetrating cranial injury is a potentially life-threatening condition. The majority of war injuries are high-velocity penetrating cranial injuries; but in civilian cases, most penetrating cranial wounds are low-velocity type. We report an interesting case of transorbital penetrating cranial injury with a knife-sharpening stone made up of ceramic in a 28-year-old male. The pertinent literature is reviewed and management of such cases is discussed.
