Ambient Air Non-Methane Volatile Organic Compound (NMVOC) Study Initiatives in India–A Review  [PDF]
Amrita Talapatra, Anjali Srivastava
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.21003
Abstract: Different aspects of Volatile Organic Compounds (VOCs) are being investigated in details by different research groups in Indian institutes. The spectrum covers measuring technologies, source apportionment and variability studies, all these are in due process of preparing a guideline for the sustainable development in terms of industrial, infrastructural as well as overall growth of the country. Both the outdoor and indoor air quality has significant impact on human health. With special concentration on BTEX and HAPs, the health related investigations are conducted as part of interdisciplinary studies of environmental science. Newer technologies to remove VOCs under specific industrial and practical conditions are getting emerged as a comparatively new era. It addresses fields like adsorption, condensation, pervaporation, biodegradation and catalytic combustion. Besides, different kinds of biofilters have drawn significant attention nowadays. The final selection of appropriate technology depends on type and concentrations of VOCs, extent of separation required and cost involved. All these technologies are although well studied, but could not be adopted for regular commercial usage till date. There is scope to explore new horizons as well as regular monitoring on the introduced pathways to limit VOC emission in the ambient air. This review aims at a concise discussion on all the areas that come under the umbrella of non-methane VOC technologies.
Karyotypic analysis of different populations of Carthamus tinctorius Linnaeus (Asteraceae)
Anjali Malik,A Srivastava
Comparative Cytogenetics , 2009, DOI: 10.3897/compcytogen.v3i1.8
Abstract: Somatic chromosomes of Carthamus tinctorius L. were analysed. A karyotype formula for each studied population was formulated. Although all samples have 2n = 24, they could be differentiated by their karyotype formula and quantitative parameters of the karyotypes. The chromosomes were assorted into different categories on the basis of arms ratio following Levan et al. (1964). These were further subdivided into different types, on the basis of total length of the chromosomes. Based on an evolutionary point of view, variation in total chromosome length without major changes in the karyotype formula suggests that changes in the amounts of genomic DNA are proportional to the relative length of an each chromosome arm. All samples possessed symmetrical or slightly asymmetrical karyotype. The samples belonging to the same species were showing intra-specific or inter-specific chromosome polymorphism. This finding may provide useful information for Carthamus evolutionary, genetic, and breeding studies.

M. P. Sharma, Anjali Krishnamurthy, Bipin K. Srivastava
World Journal of Condensed Matter Physics (WJCMP) , 2011, DOI: 10.4236/wjcmp.2011.14022
Abstract: Layered perovskite manganite ceramics with a nominal chemistry La1.5Ca1.5Mn2-xFexO7(x = 0.0, 0.05, 0.1, 0.3, 0.5) were prepared using sol-gel method. The manganese ions are highly mixed states of Mn3+ and Mn4+. It is found that the Mn3+/Mn4+ ratio decreases with the Fe doping content increasing. The conductivity and magnetoresistance (MR) were studied. The sample of x = 0.05 shows metal insulator transition (MIT) at 135 K. The MIT peak temperature (Tp) shifts towards higher temperature with increasing applied magnetic field. All the samples can be well fitted to the variable-range hopping (VRH) model. The maximum value of MR (%) [ρ(0) - ρ(H)]/ρ(0) × 100 for x = 0.05 is 34% (105 K, 7 kOe).

Pankaj Srivastava,Anjali Burande,Neeraja Sharma
Applied Computational Intelligence and Soft Computing , 2013, DOI: 10.1155/2013/265924
Abstract: It is a well-known fact that water is the basic need of human beings. The industrial wastes nearby rivers and several anthropogenic activities are responsible for deteriorating water quality of rivers in India. The present research paper deals with the design and development of soft computing system to assess the water quality of rivers Ganga and Yamuna during the Maha Kumbh 2013 in and around Sangam Zone, Allahabad, by making use of physicochemical parameters relationship. 1. Introduction The role of water in human life is important as it plays a vital role in the mechanics of human body. Human body is a water machine designed to run primarily on water and minerals. The movement of water within our cellular system also transports vital blood plasma, 92% of which is made up of water. It confirms the quality of water we consume will have severe impact on our overall state of health. Our brain contains over 80% water and controls each and every process that happens inside our body. Considering the vital role that water plays in our brain and nervous system is key to longevity. The purity of water we drink causes impact on our strength and energy level. Hindus believe that river Ganga is physically and spiritually pure and it removes all sins committed by human being during life time, normally by taking a dip in it. The mythological belief of Hindus regarding Ganga is on its threshold due to dangerous chemical contaminants related to industries and sewage system of towns close to it as well as human and animal wastes, and water quality deteriorates rapidly downstream. Nonetheless, 80% of the health problems in contemporary India come from waterborne diseases. In order to improve water quality of rivers a systematic scientific approach has been made by Meyer [1], Harmancioglu et al. [2], Rosemary et al. [3], and many other scientists in terms of their chemical, biological, and nutrient constituents. However, discrepancies appeared due to the uncertainty in the quality criteria employed and the imprecision, vagueness, or fuzziness in the decision-making output values. It is a well-known fact that decision-making processes in real life problems are too complex, and to handle such issue Zadeh introduced the concept of fuzzy [4] and consequently he published a series of papers that show how his idea can be used in real applications. The decision-making process in the presence of fuzzy variables was introduced by Jain [5] and later on Bellman and Zadeh [6] proposed application of fuzzy tools in the fuzzy environment. During the last phase of the twentieth

Journal of Biosciences and Medicines (JBM) , 2016, DOI: 10.4236/jbm.2016.41009
Abstract: Polymers are being used extensively in drug delivery due to their surface and bulk properties. They are being used in drug formulations and in drug delivery devices. These drug delivery devices may be in the form of implants for controlled drug delivery. Polymers used in colloidal drug carrier systems, consisting of small particles, show great advantage in drug delivery systems because of optimized drug loading and releasing property. Polymeric nano particulate systems are available in wide variety and have established chemistry. Non toxic, biodegradable and biocompatible polymers are available. Some nano particulate polymeric systems possess ability to cross blood brain barrier. They offer protection against chemical degradation. Smart polymers are responsive to atmospheric stimulus like change in temperature; pressure, pH etc. thus are extremely beneficial for targeted drug delivery. Some polymeric systems conjugated with antibodies/specific biomarkers help in detecting molecular targets specifically in cancers. Surface coating with thiolated PEG, Silica-PEG improves water solubility and photo stability. Surface modification of drug carriers e.g. attachment with PEG or dextran to the lipid bilayer increases their blood circulation time. Polymer drug conjugates such as Zoladex, Lupron Depot, On Caspar PEG intron are used in treatment of prostate cancer and lymphoblastic leukemia. Polymeric Drug Delivery systems are being utilized for controlled drug delivery assuring patient compliance.

ISRN Biomathematics , 2013, DOI: 10.1155/2013/342970
Abstract: Nowadays young professionals are a soft target of hypertension due to the increased work pressure and poor tolerance. Many people have high blood pressure for years without knowing it. Most of the time, there are no symptoms, but when this condition goes untreated it damages arteries and vital organs throughout the body and that is why it is also termed as the silent killer. Complications arising from hypertension could lead to stroke and heart failure. Soft computing approach provides a sharper conclusion from vague, ambiguous, and imprecise data (generally found in medical field) using linguistic variables. In this study, a soft computing diagnostic support system for the risk assessment of hypertension is proposed. 1. Introduction A human body is a complex system and there are a number of variables that affect its functioning. The abnormality in its functioning causes a number of symptoms in the form of primary stages of different diseases although the recognition of these symptoms and their mapping with the diseases precisely is not an easy one. Sometimes compications in human body may be caused by improper diagnosis or improper management of the disease or due to the inaccessibility of medical personnel [1]. The quickening speed of change and adoption of western lifestyles by people in developing countries have led to a sharp rise in the incidence of hypertension [2]. Hypertension is a medical term for high blood pressure which is a condition that occurs when the pressure in the arteries is above the normal range. According to one of the studies “Recession has had an adverse impact on jobs in India and perhaps this is one of the reasons why cases of Hypertension have gone up in past two years among young IT professionals”. Recent analysis has predicted that more than 1.56 billon people will be living with hypertension worldwide by the year 2025. It has been declared by a survey report that one of four adults in India has high BP which kills 7.5 million people worldwide each year; moreover, AIDS, diabetes, road accidents, and tuberculosis are put together. In India 23.1% men and 22.6% women have high BP a notch lower than the global prevalence of one in three adults says the World Health statistics 2012 released, 16 May 2012. Jain [3] established a decision making process phenomenon in the presence of fuzzy variables. Poli et al. [4] developed a neural network expert system for diagnosing and treating hypertension. Degani [5] discussed computerized electrocardiogram diagnosis using fuzzy approach. Charbonnier et al. [6] proposed the statistical and

Health (Health) , 2012, DOI: 10.4236/health.2012.49100
Abstract: 1The term “street children” has been used inter changeably with “children in especially difficult circumstances” in the remaining document. This paper discusses the findings of a research project which is an exploratory cum descriptive study [1] that aims to describe and examine the state and nature of the quality of life of street children accommodated at an unorganised colony in the city of Delhi. It provides a social profile of children and their families, and exploring the needs and aspirations of these children living in especially difficult circumstances. A non-probability sample of 100 street children in the age group of 5-16 years was randomly selected guided by their availability. An interview schedule was constructed and administered to gather data. The statistical analyses comprised frequencies and percentages on all the sections of the interview schedule. Thematic content analysis was used to analyse data from open-ended questions and observations. Case studies were supportive in giving an insight into the lives of children living in especially difficult circumstances. Findings suggest that the quality of life of the participants in this study was depressed due to a lack of access or substandard educational and medical facilities, or absence of emotional support from their poverty stricken families. The existing limited programmes by the government or the civil society for the welfare of street children are lacking in their focus and do not include the voices and needs of the beneficiaries. Although service providers expressed sympathy for street children, many regarded them as deviants, delinquents, future criminals, and a public nuisance. Based on the findings, it has been suggested that the street child phenomenon necessitates a partnership between governmental and non-governmental organizations to provide for policy and legislation, funding and resources to translate programs into concrete plans of action. It has further been argued that such an approach should extend to children using their resourcefulness and creativity, and show that they can be significant in development interventions. Children illustrate both the need for participatory approaches and the problems that arise when perceptions of participants conflict with those of experts.

Anjali Goel, Neetu Rani
Open Journal of Inorganic Chemistry (OJIC) , 2012, DOI: 10.4236/ojic.2012.23010
Abstract: Commonly transition metal nano particle are synthesized by physical, chemical or electrochemical methods. In the present work colloidal iridium nanoparticles were synthesized by chemical oxidation method with different surfactants like poly vinyl pyrrolidone (PVP), poly vinyl alcohol (PVA) and poly oxyethylene lauryl ether (POLE). It was found that shape and size of Ir-nano particles resulted were related to kind of capping agent (surfactant) used. The characterization of the synthesized nano particle has been carried out by UV-vis, X-ray diffraction (XRD), FT-IR, scanning electron microscopy (SEM) and transmission electron microscopic (TEM) techniques. UV-vis and FT-IR confirm the oxidation of IrCl3 into IrO2 while XRD confirms the amorphous nature of the iridium nanoparticles synthesized. The morphology and size of the particle were confirmed by TEM. The average particle size determined by Scherrer equation was about 4.12 nm to 4.23 nm with PVP, 2.74 to 3.36 nm with PVA and 20.41 to 42.25 nm with POLE. Poly oxyethylene lauryl ether particles were not further analyzed because of their large size and less stability. Further particle size was confirmed with TEM, which was 4.5 nm with PVP and 7.0 nm with PVA. The particles are spherical with no agglomeration tendency.

World Journal of AIDS (WJA) , 2016, DOI: 10.4236/wja.2016.64020
Abstract: Background: Women diagnosed with HIV/AIDS may transmit the infection to their child during pregnancy. The infection may spread during pregnancy, childbirth, or breastfeeding. However, the risk of mother-to-child transmission of HIV may be reduced by the use of HIV medications known as antiretroviral therapy (ART). Infection with HIV/AIDS is not a contraindication to pregnancy. Some women are unaware they have the disease until they become pregnant. In this case, they should begin antiretroviral therapy as soon as possible [1]. With the appropriate treatment, the risk of mother-to-child infection can be reduced to below 1% [2]. Without treatment, the risk of transmission is 15% - 45% [3]. Objective: The main aim of the study is to appreciate the declining trend of HIV in babies with HIV positive mother by implementation of PPTCT services. Methods: A retrospective study of detection of HIV positive mothers among all the antenatal patients attending OPD and including the patients coming in Emergency services and delivered in Department of Obstetrics and Gynecology at MGMMC & M. Y. Hospital, Indore, Madhya Pradesh (India) from Jan 2006 to Dec 2015 was included in the study. They were screened for HIV status and further management of all HIV positive patients.
Bacterial Surface Layer Proteins: A Promising Nano-Technological Tool for Bio-Sensing Applications  [PDF]
Anjali Sharma, Barkha Singhal
Advances in Bioscience and Biotechnology (ABB) , 2019, DOI: 10.4236/abb.2019.103004
Abstract: The phenomenal rise in the demand of biosensors accelerated their rapid development and immersive applications in the myriads of fields. The essential requirement of developing efficient bio-sensing platform is to find stable well organized interfacial architecture that can serve as an excellent matrix for binding and recognizing biomolecules. In this context, the enormous potential has been envisaged in surface layer proteins that represented themselves as most primitive and simplest self-assembled system with repetitive physicochemical properties for the molecular functionalization of surfaces and various interfaces. The prominence of S-layer proteins has been broadened by integrating genetic engineering approaches for the fine tuning of functional groups and protein domains in geometrically well-defined manner. The efficient and stable binding of various nanomaterials with S-layers in regular arrays has led to paradigmatic shift in their nano-biotechnological sensing applications. More recently, functional S-layer supported lipid membranes have been generated through covalent binding of lipid molecules either with native or recombinant S-layer proteins at nano-scale dimensions serving as “proof of concept” for the development of bio-sensing platform. Thus, in the light of benefits conferred by surface layer proteins for the development of highly efficient biosensors, an exciting path has been opened for broadening their translational applications in drug delivery, disease diagnosis, vaccines development, lab-on-chip devices etc. Therefore, this review intends to describe about the importance of surface layer proteins in the development of biosensors.
