Anticonvulsant potential of Anisomeles malabarica leaves against experimentally induced convulsions in rats
Singh Ishpinder,Singh Manjit,Singh Tajinder,Bijjem Krishna-Reddy
International Journal of Green Pharmacy , 2010,
Abstract: Anisomeles malabarica (AM) R.Br. (Lamiaceae) is an aromatic perennial herb, the leaves of which are traditionally used to treat convulsions in southern India. The present study has been designed to investigate the anticonvulsant potential of chloroform, ethyl acetate and methanol extracts of leaves of AM against pentylenetetrazole (PTZ) and maximal electroshock (MES) induced convulsions. All the three extracts were administered (i.e. 100, 200, 400 mg/kg, p.o.) for 7 days and at the end of the treatment convulsions were induced experimentally. Diazepam and phenytoin (1 mg/kg, i.p. and 25 mg/kg, i.p., respectively) were used as reference anticonvulsant drugs against experimentally induced convulsions. High doses (400 mg/kg, p.o.) of chloroform and ethyl acetate extracts both significantly decreased the extent of MES- and PTZ-induced convulsions. On the other hand, ethyl acetate extract at lowest and medium selected doses (i.e. 100 mg/kg, p.o. and 200 mg/kg, p.o., respectively, for 7 days) had also significantly attenuated PTZ-induced convulsions. However, methanol extract at any of the doses used (i.e. 100, 200 and 400 mg/kg, p.o.) did not show any significant effect on PTZ- and MES-induced convulsions. None of the extracts at doses used in the present study have altered locomotor activity and motor coordination. Hence, it may be concluded that chloroform and ethyl acetate extracts of AM leaves are effective against PTZ- and MES induced-convulsions in rats.
Analysis of Vortex Motion in Porous Media  [PDF]
Beant Singh, Chanpreet Singh
Journal of Electronics Cooling and Thermal Control (JECTC) , 2012, DOI: 10.4236/jectc.2012.22003
Abstract: In vortex motion fluid moves in curve path and the stream lines are curved. When the fluid flows between curved stream line, the centrifugal forces are setup which is counter balanced by pressure forces acting in the radial direction. The vortex motion has two types of curved motion. The first type called free vortex type, the fluid moves due to its own natural effect but energy is not added to fluid when moving in curved path. The second type called forced vortex, in which energy is added to fluid. A two dimensional steady laminar free convective flow of viscous incompressible flow in porous media voids is considered. In this paper the motion of fluid is studied while moving in the porous media. It is studied that the motion of the fluid in the porous media is vortex motion at the low Reynolds’s number, where the motion is laminar motion and the fluid obeys the laws of vortex motion.
Chromohysteroscopy—A new technique for endometrial biopsy in Abnormal Uterine Bleeding (AUB)  [PDF]
Nisha Singh, Bharti Singh
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.35A1003
Abstract:

Objective: To evaluate the role of chromohysteroscopy in improving diagnostic accuracy of endometrial biopsy in cases of AUB. Design: Cross sectional interventional study. Materials and Methods: This study was conducted on 60 women with AUB in Dept. of Obst. & Gyne at King George Medical University, Lucknow over a period of one year. All cases underwent diagnostic hysteroscopy followed by chromohysteroscopy using 2% methylene blue dye. Hysteroscopic guided biopsy was taken from stained and unstained areas followed by an endometrial aspiration biopsy from whole uterine cavity. The histopathology results of three samples were compared and analyzed in relation with staining pattern and type of AUB. Data analysis was done on SPSS version 15 of windows 2007. Results: Out of 60 cases, 11cases were found to have non hormonal pathology after chromohysterosopic biopsy. Eight (72.72%) cases were diagnosed by stained endometrial tissue, one (9.09%) by unstained tissue and three (27.27%) by endometrial aspiration. The diagnostic ability of stained tissue biopsy was significantly higher (p = 0.006) than unstained biopsy and endometrial aspiration. Conclusion: Chromohysteroscopy is a simple and effective technique for diagnosing endometrial pathology in cases of AUB.

Evaluation of EO-1 Hyperion Data for Crop Studies in Part of Indo-Gangatic Plains: A Case Study of Meerut District  [PDF]
Davinder Singh, Rajender Singh
Advances in Remote Sensing (ARS) , 2015, DOI: 10.4236/ars.2015.44021
Abstract: Due to the high number of bands in the hyperspectral image, the selection of optimum bands for crop classification is a prerequisite. The Hyperion sensor has 242 spectral bands out of which 143 useable bands were selected. The bands reflected wavelength from 400 to 1000 nm to the VNIR spectrometer and transmitted the band from 900 to 2500 nm to the SWIR spectrometer. Spectral Angle Mapping Classification (SAMC) approach and a multi-scale object oriented method are applied for crop studies. The result obtained from the accuracy assessment by comparing Ground Control Points (GCP) with the help of image spectra shows 78% of overall accuracy. This shows that these data are highly useful in studying the crop diversification.
Double Negative Left-Handed Metamaterials for Miniaturization of Rectangular Microstrip Antenna  [PDF]
G. Singh
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.26044
Abstract: In this paper, I have explored a significant concept for the miniaturization of microstrip patch antenna configuration by using the double negative (DNG) left-handed Metamaterials, which have dielectric permittivity and magnetic permeability both negative, simultaneously. It is achieved through the concept of phase-compensation by thin slab consist of the double positive (DPS) material, which have dielectric permittivity and magnetic permeability both positive, simultaneously and DNG metamaterials as a substrate of the microstrip patch antenna. By combining the DNG metamaterial slab with the slab made of DPS materials form a cavity resonator whose dispersion relation is independent of the sum of thickness of the slabs filling this cavity but it depends on the ratio of their thicknesses. This cavity constitutes by DPS and DNG material is used as substrate of the microstrip antennas and the DNG material slab is behave as phase compensator.
One Dimensional Solute Transport Originating from a Exponentially Decay Type Point Source Along Unsteady Flow Through Heterogeneous Medium  [PDF]
Premlata Singh
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.38068
Abstract: One dimensional advection dispersion equation is analytically solved initially in solute free domain by considering uniform exponential decay input condition at origin. Heterogeneous medium of semi infinite extent is considered. Due to heterogeneity velocity and dispersivity coefficient of the advection dispersion equation are considered functions of space variable and time variable. Analytical solution is obtained using Laplace transform technique when dispersivity depended on velocity. The effects of first order decay term and adsorption are studied. The graphical representations are made using MATLAB

Abstract: In this paper, using the Data Envelopment Analysis (DEA), we have measured the technical efficiency of cricket teams in the Indian Premier League. Taking the data for the 2009 season, the input used by the teams is approached by the total expenses which include players’ wage bill and wage of the support staff and other miscellaneous expenses. Output is measured by the points awarded, net run rate, profit and revenues. Efficiency scores are highly correlated with the performance in the league with a few exception, and when decomposing inefficiency into technical inefficiency and scale inefficiency it can be shown that the largest part of inefficiency can be explained by suboptimal scale of production and ineffficient transformation of inputs into outputs.

Abstract: The herbal medicine occupy distinct position right from ancient period. The plant Calotorpis procera is known by different name in different part of world like French cotton, Alarka, or Madar, Rooster tree, and Widuri. The plant is poisonous can lead to blindness if its juice is put in to the eyes. The same plant is used for Ayurvedic medicines. The medicinal properties like Calotropin isolated from latex is used as remedy for painful tooth cavities rheumatism, sy-philis, leprosy and edema, for ring worm, syphilitic soreness, and leprosy cutanous dryness and toothache. Latex is al so used in the treatment of gum bleeding and as odontagic. Flowers can all so be used for too-thache, and ringworm infection. As the adage goes excess leads to distress, the judicious use of herbal medication is recommended otherwise it will lead to complication, as described in the case report.

Abstract: Nanotechnology is defined as the study and application of 1 - 100 nm sized structures. Nanomaterials have opened avenues for the industries and scientific endeavors. These recognized for unique size, dependant physical and chemical properties (optical, magnetic, catalytic, thermodynamic, electrochemical) [1]. Most significant properties of nanoparticles is their carbon strength. It is said to be so tough that recently with a nano-sized particles i.e. carbon nanotube—a bullet proof T-shirt/vests was manufactured. Nanotechnology were firstly proposed/initiated by Nobel Prize winner Richard Feynman in 1959 [2]. This science is credited to have applications ranging from electronics, biomedicals, food, fuel cells to biosensors and even fabrics. Though every field of science progressing but still faces some lacunae and that result in development of a new technology. The thriving biomedical techniques for disorders like cancers etc. is still in developmental stage where researchers and doctors are working hard for concrete therapeutic results from such nano-techniques. On Cancers, the harmful side effects of its treatment like chemotherapy can’t be left aside which is result of one of its drug delivery methods that don’t pinpoint their intended target cells accurately rather affects whole area. Researchers in universities like Harvard and MIT have been able to attach special RNA strands, measuring about 10nm in diameter, to nanoparticles and fill the nanoparticles with a chemotherapy drug. The RNA strands get attracted to cancer cells. When the nanoparticle encounters a cancer cell it adheres to it and releases the drug into the cancer cell. This directed method of drug delivery has great potential for treating cancer patients while producing less side harmful effects than those produced by conventional chemotherapy [3]. This paper provides valuable information to the researchers, knowledge experts and policy makers regarding the application of nanotechnology and its values in science and technology. Biomedical is one of the major issues which were catered by nanotechnology.
