DIURETIC POTENTIAL OF AERVA LANATA AND ECBOLIUM LIGUSTRINUM ROOT EXTRACTS

Based on the ethnobotanical importance as diuretics Aerva lanata and Ecbolium ligustrinum were selected for presentscreening. Experiment was carried out on male wister strain albino rats using furosemide as standard drug. 20mg/kg and200mg/kg oral doses are selected for standard and test respectively. For quantifying the diuretic activity the urine output,urine pH, sodium, potassium and chloride levels in the urine are measured. The diuretic index value of Ecbolium ligustrinumis 1.70 and nearer to the standard furosemide value 1.80. Aerva lanata group shows less diuretic index of 1.49 compared tostandard. The ratio of the concentration of sodium ions to the potassium ions in control group was found to be 1.39 and theratio for standard, Aerva lanata and Ecbolium ligustrinum are 1.78, 1.49 and 1.68 respectively. Ecbolium ligustrinumaffected the amount of urine excreted and also the electrolyte concentration in urine. The present study concluded that rootsof Aerva lanata and Ecbolium ligustrinum are having diuretic nature

Formulating Heat Transfer Across The Head-Media Interface- HAMR

All past thermal demonstrating on warmth trade between hard disk drive (HDD) head and media regarded media as a warmth sink with uniform encompassing temperature. However in warmth helped attractive recording (HAMR) framework, the media temperature is no more uniform and the temperature at the problem area focus can reach as high as 800 to 1000 K contingent upon recording layer's Curie temperature. In this paper, both media problem area and the air bearing stream are incorporated into detailing heat exchange over the head-media interface. Numerical results for a waveguide just slider and a slider with a metallic close field transducer (NFT) are introduced to delineate the impact of HAMR media temperature

Desalination of Water

Water is very essential for all living beings. It covers nearly 70% of earth’s surface. Even though the major portion of earth is covered by water, there is severe shortage of drinking water in most of the countries across the world. Safe drinking water is vital for all forms of life though it does not provide any calories. Desalination of sea water appears as a solution for this problem. Advanced desalination technologies that are applied to seawater and brackish water prove to be effective alternatives in a variety of situations. This study mainly focuses on upcoming trends in modern desalination technologies and emphasizing the options offered by them. Desalination is a technique where the excess salts are removed from sea water or brackish water converting it into safe potable or usable water. Desalination methods are categorized into thermal processes and membrane processes. In this chapter we discuss about different thermal processes like multistage flash distillation, multiple effect distillation, vapour compression evaporation, cogeneration and solar water desalination. We also discuss about various categories of membrane processes like reverse osmosis, electro dialysis and membrane distillation methods. This chapter also concentrates on advantages and disadvantages and economical parameters involved in each of these methods

Demographics and Histopathological Patterns of Oral Squamous Cell Carcinoma at a Tertiary Level Referral Hospital in Hyderabad, India: A 5-Year Retrospective Study

Background: To study the demographics and histopathological patterns of oral squamous cell carcinoma (OSCC) reported at a tertiary level referral teaching hospital in Hyderabad, India. Materials and methods: An institutional retrospective study of biopsies sent to a tertiary level referral teaching hospital, Hyderabad. The data was collected year-wise for a period of 5 years from 2007 to 2011 with reference to age, sex, site involved and final diagnosis based on the histopathological findings. Results: A total of 1,005 oral biopsies were reviewed. Of these, OSCC was seen in 234 cases (23.28%). Buccal mucosa (47.7%) was the most frequently involved site followed by tongue (27.6%). Most of the OSCC patients were in the age group of 41 to 50 years, males and histopathologically well-differentiated (62%). Conclusion: This study showed that OSCC is widespread in the patients of this region

3d Modeling and Detailing of Silumin Piston With Static Analysis

Piston is the part of engine which converts heat and pressure energy liberated by fuel combustion into mechanical works. Engine piston is the most complex component among the automotives. Weight reduction has been gaining importance in automobile field because reducing in weight decreases load on the engine and thus increasing efficiency of the engine. As we all Know that Piston is made of Aluminum Alloy Such that its weight is less. The automobile industry has shown increased interest in replacing the Piston with the material having high strength to weight ratio.   Therefore the objective of this project is to present a general study on the performance comparison of composite Piston and Aluminum Alloy Piston. Dimensions and specifications used in modeling are collected from the actual Piston of Hero-Honda Splendor Bike. The Piston is modeling in solid Works

In vitro antimicrobial screening of methanolic extracts of Cleome chelidonii and Cleome gynandra

Antimicrobial activity of methanolic extracts of plants was screened by disc diffusion assay against four bacteria and four fungal cultures. Streptomycin (10 ?g/disc) and nystatin (10 ?g/disc) are used as standards for bacteria and fungi respectively. Minimum inhibitory concentration (MIC) of the extracts was evaluated through micro broth dilution method. The antimicrobial potency of plant extracts was assessed by their zone of inhibition and activity index values. Total activity of extracts was evaluated to quantitatively compare the activity of two plants. Methanolic extract of Cleome gynandra showed maximum antibacterial activity against Staphylococcus aureus (IZ- 22 ± 0.22 mm, AI-0.917, MIC- 0.039 mg/mL, MBC- 0.039 mg/mL). Maximum antifungal potential was shown by C. chelidonii against Candida albicans (IZ- 25 ± 0.92 mm, AI-1.000, MIC- 0.039 mg/mL, MFC- 0.039 mg/mL). Both the extracts exhibited good antimicrobial activity with low range of MIC

Sympathetic Effects of Internal Carotid Nerve Manipulation on Choroidal Vascularity and Related Measures

Purpose: To investigate specific effects of denervation and stimulation of the internal carotid nerve (ICN) on the choroid and retina. Methods: Female Sprague Dawley rats underwent unilateral ICN transection (n = 20) or acute ICN electrical stimulation (n = 7). Rats in the denervation group were euthanized 6 weeks after nerve transection, and eyes were analyzed for changes in choroidal vascularity (via histomorphometry) or angiogenic growth factors and inflammatory markers (via ELISA). Rats in the stimulation group received acute ICN electrical stimulation with a bipolar cuff electrode over a range of stimulus amplitudes, frequencies, and pulse widths. Choroidal blood flow and pupil diameter were monitored before, during, and after stimulation. Results: Six weeks after unilateral ICN transection, sympathectomized choroids exhibited increased vascularity, defined as the percentage of choroidal surface area occupied by blood vessel lumina. Vascular endothelial growth factor (VEGF) and VEGF receptor-2 (VEGFR-2) protein levels in denervated choroids were 61% and 124% higher than in contralateral choroids, respectively. TNF-α levels in denervated retinas increased by 3.3-fold relative to levels in contralateral retinas. In animals undergoing acute ICN electrical stimulation, mydriasis and reduced choroidal blood flow were observed in the ipsilateral eye. The magnitude of the reduction in blood flow correlated positively with stimulus frequency. Conclusions: Modulation of ICN activity reveals a potential role of the ocular sympathetic system in regulating endpoints related to neovascular diseases of the eye
