Mobile Operating Systems
Vipin Kamboj,Hitesh Gupta
International Journal of Engineering Innovations and Research , 2012,
Abstract: Mobile phones are used by every people in today’s life. We use mobile phones without knowing the different factors that a mobile used including its technology, operating system, CPU ,RAM etc. Many types of operating system are used by different mobile. Every operating system has their advantage
Dual Allosteric Effect in Glycine/NMDA Receptor Antagonism: A Comparative QSAR Approach
Manish Sharma,Vipin B. Gupta
Pharmaceuticals , 2010, DOI: 10.3390/ph3103167
Abstract: A comparative Hantzsch type QSAR study was conducted using multiple regression analysis on various sets of quinoxalines, quinoxalin-4-ones, quinazoline-2-carboxylates, 4-hydroxyquinolin-2(1 H)-ones, 2-carboxytetrahydroquinolines, phenyl-hydroxy-quinolones, nitroquinolones and 4-substituted-3-phenylquinolin-2(1 H)-ones as selective glycine/NMDA site antagonists. Ten statistically validated equations were developed, which indicated the importance of CMR, Verloop’s sterimol L1 and Clog P parameters in contributing towards biological activity. Interestingly, normal and inverse parabolic relationships were found with CMR in different series, indicating a dual allosteric binding mode in glycine/NMDA antagonism. Equations reveal an optimum CMR of 10 ± 10% is required for good potency of antagonists. Other equations indicate the presence of anionic functionality at 4-position of quinoline/quinolone ring system is not absolutely required for effective binding. The observations are laterally validated and in accordance with previous studies.
ANTIMICROBIAL ACTIVITY OF SESBANIA GRANDIFLORA (L.) PERS.
Kachroo Vipin,Gupta Kumar Arun,Gupta Rajesh
International Research Journal of Pharmacy , 2011,
Abstract: Sesbania grandiflora (L.) Pers is a plant that is used in traditional medicine for the treatment of cold,fever, stomach disorder, diarrhea and jaundice and as skin cleanser. To evaluate the scientific basis for the use of the plant, the antimicrobial activities of extracts of the stem bark and leaves were evaluated against some common gram negative and gram positive bacteria and fungi. The study also investigated the chemical constituents of the plant and the effect of temperature and pH on its antimicrobial activity. Sesbania grandiflora (L.) Pers has broad spectrum antibacterial activity and a potential source ofnew classes of antibiotics that could be useful for infectious disease chemotherapy and control.The phytochemical constituents of the dried powdered plant parts were extracted using aqueous and organic solvents (acetone and ethanol). The antimicrobial activity of the concentrated extracts was evaluated by determination of the diameter of zone of inhibition against both gram negative and gram positive bacteria and fungi using the disc diffusion method.

Functional characterization of L-tryptophan transport across mammalian cornea
Mahendra Singh Rathore,Vipin Bihari Gupta
International Journal of Drug Delivery , 2011,
Abstract: In last few years transporter targeted drug delivery has drawn attention of research to identify and explore various nutrient transport systems including amino acid transporters for better drug delivery. The aim of present research work is to investigate the transport characteristics of L-tryptophan (L-try) across goat cornea. Transport of L-try was investigated using a glass diffusion cell for effect of concentration, pH, presence of other amino acids or metabolic inhibitor or dipeptide and tripeptide. The amount of L-try transported increased as the pH of L-try aqueous solution increased from 5 to 9. Inhibition was observed in L-try transport in absence of sodium ions where L-try solution was made isotonic with dextrose. Amino acids like L-histidine, L-arginine, L-lysine (cationic), L-glutamic acid, L-aspartic acid (anionic), glycine and L-proline (neutral) inhibited the L-try transport as compared to control (L-try alone). In presence of sodium azide and Ouabain the inhibition in L-try transport across goat cornea was observed while no marked inhibition was observed on L-try transport across goat cornea in presence of aspartame and glutathione. The L-try transport was favored up to concentration 1% w/v and at higher pH in presence of sodium ions through excised goat cornea. Functional presence of a sodium dependent L-try transport system as inhibited by ouabain having affinity to cationic and neutral amino acid is evident on goat cornea.

Design and Development of Anti-Spoofing based measurement of Heart Rate, Temperature and Blood Oxygen level using Low Cost Microcontroller
Vipin Gupta,Kunal Maurya,Anup Kumar Agarwal
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: The instrument which is used in home or in clinics should be cost effective and provide quality of health services. The medical industry is growing in terms of integration. Individual instruments are very costly so the need arises of making a device which has low cost and it measures some of physiological parameters of the body in a single device. This paper describes the design and development of a device which combines three physiological parameters of body i.e. heart rate, arterial blood oxygen concentration and body temperature. The output is displayed on LCD using low cost microcontroller.

Herpes simplex virus type 2: Seroprevalence in antenatal women
Rathore Shagufta,Jamwal Aditi,Gupta Vipin
Indian Journal of Sexually Transmitted Diseases , 2010,
Abstract: Aims: To determine the seroprevalence of herpes simplex type 2 (HSV-2) infection in pregnant females, assess the frequency of unrecognized infection and identify the demographic profile and risk factors associated with the seroprevalence. Materials and Methods: Two hundred randomly selected, asymptomatic pregnant females attending the Obstetrics and Gynecology Outpatient Department for a routine antenatal check-up constituted the study group. Serum specimens were screened for HSV-2 infection by detecting IgG class antibodies against HSV-2-specific glycoprotein G-2 using an enzyme-linked immunosorbent assay kit. Results: A seroprevalence of 7.5% was found in our study. Seropositivity was maximum in the age group ≥30 years (22.20%), followed by 26-30 years (9.7%), 21-25 years (2.20%) and ≤20 years (0%). HSV-2 seropositivity was found to be significantly associated with increasing age, parity, number of sexual partners, duration of sexual activity and history of abortions (P < 0.05). No statistically significant correlation was observed between seropositivity and other demographic variables such as place of residence, education, annual family income and occupation (P > 0.05). No statistically significant association of seropositivity with present or past history suggestive of other sexually transmitted infections was found. None of our cases tested positive for human immunodeficiency syndrome (HIV). Conclusion: A relatively low prevalence of HSV-2 seropositivity was found in our study, with a high frequency of unrecognized and asymptomatic infections. Our findings suggest that type-specific serotesting could be an efficient strategy to diagnose clinically asymptomatic HSV-2 infections and, therefore, to reduce the risk of HSV-2 and HIV sexual transmission by prophylactic counseling against unprotected intercourse. It may also be a useful adjunct in detecting cases who present with symptoms not directly suggestive of genital herpes.
Improving Capacity of soft Handoff Performance in Wireless Mobile Communication using Macro Diversity
Vipin Kumar Saini,,Dr. Sc. Gupta
International Journal on Computer Science and Engineering , 2011,
Abstract: The soft handoff is a process on transferring the on going call from one radio resource to another radio resource without any interruption. Rather, mobile unit looks next base station for possible new connection without breaking the old connection. This transfer of call takes place, when the mobile unit moves far away from old base station and approach toward new base station. At the far away distance from old base station, the signal to noise power at the mobile unit becomes poorer and the service quality get degrade. At this far away distance mobile unit may see the another new base station, which may provide the better signal to noise ratio of the same signal via mobile switching center (MSC). Thus the mobile unit may get the same signal from the two different base stations simultaneously. The capacity of the CDMA communication network depends on the diversity technique used. The capacity gain of CDMA communication network can be defined by the comparison of network capacity with macro diversity and without macro diversity. In This paper we represented the capacity as number of users increases with Micro diversity as compared to capacity without Micro diversity.
