Pooja S.K. Rai,Sangita Kamath,Amruta A. Bakshi,Smita A. Deokar
International Journal of Research in Medical Sciences , 2013, DOI: 10.5455/2320-6012.ijrms20130510
Abstract: Background: Antioxidant depletion occurring in chronic renal failure patients is an important cause of associated morbidity & mortality, which in turn imposes a great socioeconomic burden of health care. Early diagnosis & targeted management of this preventable deficiency may have a positive impact on the management of co morbidities associated with chronic renal failure. Aims & Objectives: To evaluate the status of antioxidants as an early indicator of cardiometabolic risk in chronic renal failure patients. Settings & Design: This was a randomised case Control study including 10 controls of either sex with normal renal function between age group 20-60 years and 15 patients of chronic renal failure on dialysis between the age group of 16 - 60 years. Methods: 12 hour fasting venous blood samples were collected from all the participants and were assayed for various antioxidants. Statistical analysis: Results were analyzed by unpaired t test, p value was determined & Correlation coefficient was calculated amongst various parameters. Results: In the present study, significantly low levels of vitamin C ( Cases: 0.367 ± 0.13 mg/dl controls: 1.324 ± 0.61 mg/dl; p < 0.01) & vitamin E (cases: 0.235 ± 0.102 mg/dl, controls (0.854 ± 0.28 mg/dl; p < 0.01) were observed in chronic renal failure patients as compared to controls. Conclusion: Diminished levels of Vitamin C & E in our study may be an indicator of increased oxidative stress which can be a responsible factor for increased incidence of cardiovascular complications. Supplementing these patients with recommended dosage of these vitamins may provide an essential tool to reduce the burden of suffering. [Int J Res Med Sci 2013; 1(2.000): 87-92]
Induction motor voltage flicker analysis and its mitigation measures using custom power devices: A case study
International Journal of Engineering Science and Technology , 2010,
Abstract: This paper suggests methods for estimating short time flicker (PST) severity on 22/3.3 kV network supplying induction motor loads of municipal integrated water pumping system. The impact of additional connection of induction motors to the same system has been analyzed. Measurements are done at the point of common coupling (PCC) to identify background short time flicker levels and the contribution of the already operating induction motors. The paper also analyses and compares different voltage flicker mitigation methodologies to assess their performance with change in line impedance phase angle for this particular application. Here, Matlab-7.01/PSB is used to present the detailed results of all voltage flickers compensating methodologies and to assess the impact of line impedance X/R sweep on effectiveness of custom power devices. It is observed that distribution static synchronous compensator (DSTATCOM) is found more effective for compensating voltage flicker generated by the induction motor load.

Journal of Indian Association of Pediatric Surgeons , 2005,
Abstract: A frequently unrecognized and potentially devastating form of penile strangulation is that caused by human hair. Hair tourniquet syndrome frequently occurs during the time period when post partum mothers are experiencing increased hair loss. The majority of cases are thought to be accidental, however possibility of child abuse should be considered in every case.

β-Galactosidase Leakage from Escherichia coli Points to Mechanical Damageas Likely Cause of Carbon Nanotube Toxicity  [PDF]
Smita Amarnath, Mohammad A. Hussain, Vidyanand Nanjundiah, A. K. Sood
Soft Nanoscience Letters (SNL) , 2012, DOI: 10.4236/snl.2012.23008
Abstract: We show that the cytotoxic effect of carbon nanotubes (CNTs) on bacteria is mediated by mechanical damage to the cell wall and membrane. Two β-galactosidase-producing strains of Escherichia coli harboringgenomically integrated reporter gene constructs, namely pchbB:lacZand prpoS:lacZ, were used for the purpose. We first verified that CNTs result in an inhibition of cell growth. Enzyme activity was determined using a reporter gene assay in which CNTs were used without the lysis buffer (containing detergent). β-galactosidase activity in the presence of CNTs alone measured several fold more than the controls used (without nanotubes). This suggests that CNTs damage the cell membrane in a manner similar to the detergent in the lysis buffer and render E. coli cell walls porous, causing cell contents including enzymes to leak out into the medium. Our results support the hypothesis that mechanical damage to bacterial cell membranes is the prevailing cause of CNT-cytotoxicity.

National Journal of Community Medicine , 2012,
Abstract: Purpose: Purpose of the study is to study the pattern of presentation of metastatic lesions of the peripheral lymph nodes for various malignant tumors and for confirmation of metastatic lesions in cases of a known or an occult primary. Methods: Total 140 cases of metastatic lesions of the lymph node were studied from January 2003 to December 2004 by Fine Needle Aspiration Cytology in cytology department of B.J.Medical college, Ahmedabad. Results: Squamous cell carcinoma was the most common metastatic lesions of the lymph node and comprised about 80%. Metastatic lesions of lymph node occur more commonly after age of 40 years and more common in male than female except metastatic lesion form carcinoma of breast .Cervical lymph nodes were common site for metastasis for squamous cell carcinoma and axillary lymph nodes were common site for metastasis from breast malignancy. Conclusion: FNAC is cost-effective, reliable, rapid and inexpensive procedure in diagnosis of lymphadenopathy. Metastatic lesions confirmed by FNAC also give a clue to the nature and site of primary.
Honey dressing in pediatric burns
Bangroo A,Khatri Ramji,Chauhan Smita
Journal of Indian Association of Pediatric Surgeons , 2005,
Abstract: The medicinal properties of honey have been recognized since antiquity. Although used as an adjuvant method of accelerating wound healing from ancient times, honey has been sporadically used in the treatment of burns. Honey acts mainly as a hyperosmolar medium and prevents bacterial growth. Because of its high viscosity, it forms a physical barrier, and the presence of enzyme catalase gives honey an antioxidant property. Its high-nutrient content improves substrate supply in local environment promoting epithelialization and angiogenesis. In pediatric burn patients no exclusive study has been conducted using honey as a burn dressing. An attempt is being made to evaluate the effect of honey in the management of burns in pediatric patients.

Smita B. Joshi,A. R. Jani
ISRN Renewable Energy , 2013, DOI: 10.1155/2013/746189
Abstract: The objective of the present research work is to design user friendly solar cooker which can be commercialized too. This cooker is designed, developed, and tested in our laboratory. The basic principle is to incorporate heating into material by photovoltaic effect and thermal treatment. Different temperatures inside the solar cooker were measured and profile of solar cooker was studied for several days during April, May, and June 2012. It is observed that the designed cooker needs the boosting of only 30 watt power which is generated by a small solar panel connected with it. Heater connected with it can be powered by a solar panel of 75 watt. This boosting can reduce the cooking time. Different recipes were prepared to test its actual performance. 1. Introduction Food is one of the basic needs like water and air. Food preparation requires a fuel which may be wood, coal, cow dung, liquid petroleum gas, and electricity consuming induction heaters or microwave. Availability of these nonrenewable sources is a burning task. Moreover, it produces pollution which leads to imbalance in the nature. Solar cooker either box type or concentrating type can be one of the solutions of this critical problem. The solar cookers available in national and international market are not as popular as they should be. The objective of our research is to design user-friendly solar cooker which can cook a little faster than the conventional box type solar cooker for more than 300 days per year. The electrically boosted heater has made it 24 hours usable cooker. 2. Materials and Methods Figure 1 shows the schematic diagram of Photo-Thermo solar cooker. Photo-Thermo solar cooker was constructed using a stainless steel casserole and a DC heater. The heater was fixed inside the casserole with screws. Stainless still pot was used for cooking in the casserole while aluminum pots were used in Star and GEDA cookers. Figure 1: Schematic diagram of Photo-Thermo solar cooker. The Photo-Thermo solar cooker is a photovoltaic and thermal hybridized solar cooker. It is connected to a 12 volt 40 ampere-hour battery. This battery will be charged by a solar panel of 75?watt. To decide the minimum requirement of wattage for cooking, we operated the cooker with a power supply. This testing was indoor testing under all controlled parameters like wind, ambient temperatures, and humidity, and so forth. The insolation and ambient temperature data were given by Sardar Patel Renewable Energy Institute, SPRERI, situated at Gujarat, India. Horizontal insolation was recorded by pyranometer with ±2% accuracy.
