Abstract
This study describes the potential use of steel-making slag as an arsenic-removal medium. Systematic analysis of slag material revealed a composition of oxides of calcium, iron, silicon, and phosphorous. Under the experimental conditions of this study, the equilibrium time was shown to be 2 hours, and the removal capacity to be 99%, with an adsorbent loading capacity of 1.25g/l. The adsorption kinetics were shown to follow a pseudo-second-order rate equation, and the adsorption isotherm closely followed both the Langmuir and Freundlich isothermic models. Variations in solution pH levels demonstrated that with a decrease in the initial solution pH, the adsorption capacity decreases. This is attributed to the leaching of silica and phosphate from the slag to the solution, which imparted a competing effect for adsorption sites. However, with an alkaline pH, such leaching was reduced, and due to formation of calcium carbonate from the leached calcium from the slag material, the arsenic removal efficiency increased as it was co-precipitated with calcium carbonate.

Abstract
BACKGROUND Febrile illness is the most common symptom experienced by patients suspected of having malaria, especially in the malaria endemic areas of northeast India. Hospital-based data from two districts of upper Assam, namely Golaghat and Tinsukia, were analysed to assess the prevalence of malaria among inpatients who reported to health centres with febrile illness. METHODS A total of 16 hospitals were selected for the study. These included six government hospitals (three in rural and three in urban areas) and 10 private hospitals, which included four tea-garden hospitals. Selection was dependant on the availability of patients and inpatient treatment facilities. During the study, a total of 350 inpatients reported to the selected hospitals with fever; 324 were suspected of having malaria and were interviewed and included in the study. RESULTS The average age of patients was 24.2±15.2 years and 63.3% (205/324) of them were male. The majority of patients (77.5%; 251/324) belonged to the lower household income category (<5000 Indian rupees) and travelled to the nearest town or city for treatment. Overall, the prevalence of malaria (as diagnosed by clinical examination and blood tests) across the different categories such as location, types of hospitals and household income was found to be 29.9% (97/324). Multivariate analysis revealed that the adjusted odds ratios (AOR) of malaria cases was higher based on location (2.13), type of health centre (1.75) and the distance travelled to a health centre (2.09). The mean duration of hospital treatment was 4.2±3.6 days and the delay in reporting to hospital was 3.9±2.6 days. CONCLUSION The study emphasises the need to strengthen and improve the treatment facilities for malaria in government hospitals, and to create more awareness among people regarding early treatment, especially in the rural periphery villages of the endemic areas.

Abstract
Bulbar Palsy is B/L impairment of function of cranial N. 9, 10, 11, 12 at lower motor neuron level either at nuclear or fascicular level in medulla or B/L lesion of lower cranial N. outside brainstem. We present case of viral hepatitis who initially presented with classical signs and symptoms of hepatitis B followed by characteristic features of bulbar palsy in form of difficulty in swallowing and slurring of speech reduced gag reflex, weak palatal movement. Other causes for bulbar palsy were excluded and indirect laryngoscopy confirmed presence of bulbar palsy. Patient had no previous neurological abnormality, there are many studies in the past for association of hepatitis B and bulbar palsy but no one confirmed about a direct association between hepatitis B and bulbar palsy. To best of knowledge this is the first case report which shows direct association between hepatitis B and bulbar palsy.

Abstract
Dye-sensitized solar cells (DSSCs) with fruit extracts, of Melastoma malabathricum L. as sensitizer, were fabricated. The fruit dye was extracted in two different solvents; de-ionized water (MMD) and ethanol (MME). The dye was subjected to UV-Vis and DSC studies. UV-Vis studies show absorption of light for a wider range of wavelength for MMD as compared to MME. Both MMD and MME were found to be stable till 121°C, as shown by DSC studies, beyond which MME showed unstable behavior. FTIR spectra of MMD and MME along with dye adsorbed TiO2 were recorded. MMD showed better adsorption with TiO2 than with MME. Voc, Jsc and efficiencies of the MMD sensitized solar cells were obtained in the ranges 420-430 mV, 1.25-1.50 mA cm(-2) and 1.11-1.37% respectively, while for MME sensitized solar cells they were in the ranges 370-380 mV, 0.63-0.87 mA cm(-2) and 0.41-0.72% respectively. Preliminary investigation on stability of DSSCs which were fabricated using both the extracts revealed sharp drop in efficiency of DSSC with MME in comparison to DSSC with MMD as sensitizer.

Abstract
We report a comparative study of the features in dissociative double ionization by high energy electron impact of N2 and CO molecules. The ratio of cross-section of charge symmetric dissociative ionization to non-dissociative ionization (CSD-to-ND ratio) and the kinetic energy release (KER) spectra of dissociation are experimentally measured and carefully corrected for various ion transmission losses and detector inefficiencies. Given that the double ionization cross sections of these iso-electronic diatomics are very similar, the large difference in the CSD-to-ND ratios must be attributable to the differences in the evolution dynamics of the dications. To understand these differences, potential energy curves (PECs) of dications have been computed using multi-reference configuration interaction method. The Franck-Condon factors and tunneling life times of vibrational levels of dications have also been computed. While the KER spectrum of N2 (++) can be readily explained by considering dissociation via repulsive states and tunneling of meta-stable states, indirect dissociation processes such as predissociation and autoionization have to be taken into account to understand the major features of the KER spectrum of CO(++). Direct and indirect processes identified on the basis of the PECs and experimental KER spectra also provide insights into the differences in the CSD-to-ND ratios.

Abstract
Glutathione S-transferases (GSTs) belong to a super family of phase II detoxification enzymes, which play an important role in protecting cells from damage caused by endogenous and exogenous compounds by conjugating reactive intermediates with glutathione to produce less reactive water-soluble compounds. In the present study, we determined the frequencies of two polymorphisms in exon 5 and exon 6 of GSTP1 gene in 500 normal individuals from Delhi. GSTP1 polymorphism was analysed by PCR-RFLP using amplification refractory mutation system (ARMS) assay. Two polymorphic sites in GSTP1 (Ile105 → Val105; Ala114 → Val114) have been analysed simultaneously, which results in four alleles: GSTP1*A (wild-type Ile105; Ala114), GSTP1*B (Val105; Ala114), GSTP1*C (Val105; Val114) and GSTP1*D (Ile105; Val114). The GSTP1 allele frequency in Delhi population was 0.663, 0.248, 0.069, and 0.020 for GSTP1*A, GSTP1*B, GSTP1*C, and GSTP1*D respectively. The frequency of Ile105 and Val105 allele was 0.683 and 0.317 respectively and it was calculated for the purpose of comparison with published data where all the four alleles were not analysed. GSTP1 alleles from Delhi population were compared with reported frequencies from all over India, and from other ethnic groups worldwide. This study would provide a basic database for future genetic studies.

Abstract
Plant products of Phyllanthus emblica Linn. are traditionally consumed for its immense nutritive and medicinal values. However, the molecular mechanism(s) by which it exerts it effects is less understood. In this study, we investigated mechanism of action of P. emblica fruit extract (PE) by studying its effect on activator protein-1 (AP-1) activity and human papillomavirus (HPV) transcription that are essential for tumorigenicity of cervical cancer cells. PE resulted in a dose-and time-dependent inhibition of DNA binding activity of constitutively active AP-1 in both HPV16-positive (SiHa) and HPV18-positive (HeLa) cervical cancer cells. PE-induced AP-1 inhibition was found mediated through downregulation of constituent AP-1 proteins, c-Jun, JunB, JunD, and c-Fos; however, the kinetics of their inhibition varied in both the cell types. Inhibition of AP-1 by PE was accompanied by suppression of viral transcription that resulted in growth inhibition of cervical cancer cells. Growth inhibitory activity of PE was primarily manifested through induction of apoptotic cell death. These results suggest that P. emblica exhibits its anticancer activities through inhibition of AP-1 and targets transcription of viral oncogenes responsible for development and progression of cervical cancer thus indicating its possible utility for treatment of HPV-induced cervical cancers.

Abstract
Breast cancer is the most common neoplasm affecting women in the western world with an average frequency of 1 in 11, developing the malignancy and it is second most common cancer in India. Variations in serum levels of biochemical parameters especially alkaline phosphatase (ALP) changes may be of great help in diagnosis of breast carcinoma. Serum ALP activity was assayed in 388 histopathologically proven breast cancer patients using spectrophotometric methods and monitored association with cancer stages. Breast cancer is a female-biased disease and our study was conducted in a group of female patients with mean age of 48.67 ± 8.32 years. A significant increase in levels of ALP (809.65 ± 145.97 IU/L) was observed in stage IV of the disease. The logistic regression study gave a significant result (P < 0.001) when we compared the group of ALP level (>500 IU/L) with metastatic presentation. The present study besides being cost effective suggested the usefulness of ALP in differentiating breast cancer stages and metastasis.

Abstract
Background: Physicians have long recognized the association between diabetes mellitus and several pathologic conditions of the hand. The most commonly recognized maladies are limited joint mobility (LJM), Dupuytren's disease (DD), trigger finger (TF), and carpal tunnel syndrome (CTS). Incidence of these hand disorders has increased in the setting of diabetes. Collectively, these are described as diabetic hand syndrome. Aim: The aims were to find out the prevalence of hand disorders in diabetic patients, and to study the relation of these hand disorders with microvascular complications. Subjects and Methods: This is an observational cross-sectional case-control study done over a period of 1 year Patients of type 2 DM, of age < 65 years, who visited Gandhi Memorial Hospital, Lucknow were enrolled and were described as cases. Age- and sex-matched nondiabetic individuals were taken in the control group. The data were analyzed using software SPSS. SPSS Inc. Released 2008. SPSS Statistics for Windows, Version 17.0. Chicago: SPSS Inc. Means and standard deviations were computed; the Student t-test and Chi-square (χ2) test were used as appropriate. Results: A total of 400 subjects were studied, 200 each in the case and control groups. Of total 200 diabetic patients, 30% (60/200) patients had neuropathy, 37.5% (75/200) had nephropathy, and 44.5% (89/200) patients had retinopathy. In the study population, 67% patients were having one or more hand disorders, in which LJM was found in 40.5% (81/200) patients, DD was found in 19% (38/200) patients, TF in 16.5% (33/200), and CTS in 14% (28/200) patients. Conclusions: This study shows a high prevalence of hand disorders in diabetic patients and also correlates with the duration of type 2 DM, LJM being the most common hand disorder and more common in patients who have microvascular complications.

Abstract
Signal transducer and activator of transcription 3 (STAT3) is an oncogenic transcription factor constitutively active and aberrantly expressed in cervical cancer. However, the functional role of STAT3 in regulation of HPV's viral oncogene expression and downstream events associated with cervical carcinogenesis is not known. Our present study performed on HPV16-positive cervical cancer cell lines (SiHa and CaSki) and primary tumor tissues revealed a strong positive correlation of constitutively active STAT3 with expression of HPV16 E6 and E7 oncoproteins and a negative association with levels of p53 and pRB. Pharmacologic targeting of STAT3 expression in cervical cancer cell lines either by STAT3-specific siRNA or blocking its tyrosine phosphorylation by AG490 or curcumin led to dose-dependent accumulation of p53 and pRb in cervical cancer cells. Interestingly, the suppression of STAT3 expression or activation was associated with the gradual loss of HPV16 E6 and E7 expression and was accompanied by loss of cell viability. The viability loss was specifically high in HPV16-positive cells as compared to HPV negative C33a cells. These findings substantiate the regulatory role of STAT3 in HPV16-mediated cervical carcinogenesis. Leads obtained from the present study provide a strong rationale for developing novel STAT3-based approaches for therapeutic interventions against HPV infection to control cervical cancer.

Abstract
The glutathione S-transferases (GSTs) are involved in the metabolism of many xenobiotics, including an array of environmental carcinogens, pollutants, and drugs. Genetic polymorphisms in these genes may lead to inter- individual variation in susceptibility to various diseases. In the present study, GSTM1 and GSTT1 polymorphisms were analysed using a multiplex polymerase chain reaction in 500 normal individuals from Delhi. The frequency of individuals with GSTM1 and GSTT1 null genotypes were 168 (33.6%) and 62 (12.4%) respectively, and 54 (10.8%) were having homozygous null genotype for both the genes GSTM1 and GSTT1 simultaneously. The studied population was compared with reported frequencies from other neighbouring state populations, as well as with those from other ethnic groups; Europeans, Blacks, and Asians. The prevalence of homozygous null GSTM1 genotype is significantly higher in Caucasians and Asians as compared to Indian population. The frequency of GSTT1 homozygous null genotypes is also significantly higher in blacks and Asians. We believe that due to large number of individuals in this study, our results are reliable estimates of the frequencies of the GSTM1, GSTT1 in Delhi. It would provide a basic database for future clinical and genetic studies pertaining to susceptibility and inconsistency in the response and/or toxicity to drugs known to be the substrates for GSTs.

Abstract
AIM Role of blood C - reactive protein levels in upper urinary tract infection and lower urinary tract infection in adult patients (>16 years). MATERIAL AND METHODS Study included 2 groups of patients -Test group (n=58). Control group (n=28).Test group further classified into 2 groups- a). Patients having upper urinary tract infection b). Patients having lower urinary tract infection. Patients were subjected to following tests - complete hemogram, blood C-reactive protein levels, urinalysis. RESULTS The mean value of C-reactive protein in the cases of upper urinary tract infection 127.33 mg/L which is statistically significantly raised when compared to control(t-value 12.370 and p-value<0.01). C-reactive protein was significantly raised in upper urinary tract infection in comparison to control group( p<0.01), while in lower urinary tract infection this difference was insignificant (p<0.05). CONCLUSION C-reactive protein has a good diagnostic role in differentiating upper and lower urinary tract infection. The simple size of our study is very small to say these authentically, hence, further studies of large number of cases is required.

Abstract
BACKGROUND AND OBJECTIVES Tribal men's reluctance in sharing responsibilities as supportive partners in reproductive and sexual health matters debar women from their sexual rights coupled with their negligence in health care and lesser utilization of reproductive health facilities. As a matter of fact a large proportion of ill health particularly related to sexually transmitted infections (STIs) suffered not only by men but also by their spouses. The present study was planned among one of the primitive tribes of Madhya Pradesh to understand the knowledge of males about reproductive tract infection (RTI)/STI/HIV/AIDS, RTI symptoms suffered, perception on sexual health, utilization of health services and to improve the knowledge by intervention of need based IEC (information, education, communication) strategy. METHOD The study was conducted among 400 currently married men in the age group of 15-40 yr in one of the primitive tribes, Baigas of Dindori district of Madhya Pradesh. Eighteen villages were explored in the study. The IEC intervention was made by using quasi-experimental before and after with control design. RESULT The baseline data generated indicated that Baigas male were poorly informed about RTI (18%), STI (21.5%) and HIV/AIDS (10%). Further, men also projected misconception on different aspects of sexuality. Women's views recorded also suggested a disturbing trend regarding male involvement in reproductive health particularly related to STIs. INTERPRETATION & CONCLUSIONS After intervention of IEC targeting male population in age group 15 - 40 yr by adopting a before and after with controls design the awareness was improved significantly. The utilization of the health services was also improved significantly. The study recommends replication of the IEC strategy designed in other Baiga villages for improving the reproductive health of the tribe.

Abstract
Background. Evidence suggests that insufficient sleep duration is associated with an increased likelihood for hypertension. Both short (<6 hours) and long (>8 hour) sleep durations as well as hypertension are more prevalent among blacks than among whites. This study examined associations between sleep duration and hypertension, considering differential effects of race and ethnicity among black and white Americans. Methods. Data came from a cross-sectional household interview with 25,352 Americans (age range: 18-85 years). Results. Both white and black short sleepers had a greater likelihood of reporting hypertension than those who reported sleeping 6 to 8 hours. Unadjusted logistic regression analysis exploring the race/ethnicity interactions between insufficient sleep and hypertension indicated that black short (<6 hours) and long (>8 hours) sleepers were more likely to report hypertension than their white counterparts (OR = 1.34 and 1.37, resp.; P < 0.01). Significant interactions of insufficient sleep with race/ethnicity were observed even after adjusting to effects of age, sex, income, education, body mass index, alcohol use, smoking, emotional distress, diabetes, coronary heart disease, and stroke. Conclusion. Results suggest that the race/ethnicity interaction is a significant mediator in the relationship between insufficient sleep and likelihood of having a diagnosis of hypertension.

Abstract
Background Household survey data of Changlang district, Arunachal Pradesh, were used in the present study to assess the prevalence of opium use among different tribes, and to examine the association between sociodemographic factors and opium use. Methods A sample of 3421 individuals (1795 men and 1626 women) aged 15 years and older was analyzed using a multivariate logistic regression model to determine factors associated with opium use. Sociodemographic information such as age, education, occupation, religion, ethnicity and marital status were included in the analysis. Results The prevalence of opium use was significantly higher (10.6%) among men than among women (2.1%). It varied according to age, educational level, occupation, marital status and religion of the respondents. In both sexes, opium use was significantly higher among Singpho and Khamti tribes compared with other tribes. Multivariate logistic regression indicated that opium use was significantly associated with age, occupation, ethnicity, religion and marital status of the respondents of both sexes. Multivariate rate ratios (MRR) for opium use were significantly higher (4–6 times) among older age groups (≥35 years) and male respondents. In males, the MRR was also significantly higher in respondents of Buddhist and Indigenous religion, while in females, the MRR was significantly higher in Buddhists. Most of the female opium users had taken opium for more than 5 years and were introduced to it by their husbands after marriage. Use of other substances among opium users comprised mainly tobacco (76%) and alcohol (44%). Conclusions The study reveals the sociodemographic factors, such as age, sex, ethnicity, religion and occupation, which are associated with opium use. Such information is useful for institution of intervention measures to reduce opium use.

Abstract
Breast cancer evaluation and early diagnosis are core complexity worldwide and an ambiguity for scientists till date. Nano-materials are innovative tools for rapid diagnosis and therapy, which may induce an immense result in the field of oncology. Their exceptional size-dependent properties make them special and superior materials and quite indispensable in several fields of the human activities. The major obstacle in finding cure for malignant breast cancer is to increase in development of resistances for tumors to the therapeutic treatments. The widespread mammo-graph particle is being developed by nations to diagnosis disease in primitive stage to decline the mortality rates caused by breast carcinoma. The advancement of nano-particle based diagnostic tools facilitates in evaluation and provides encouraging development in breast cancer therapeutics. In this compact review, efforts have been made to compose the current advancements in the area of functional nano-particles. Furthermore, in vivo and in vitro applications of nano-materials in breast cancer management are also discussed.

Abstract
Metal nanoparticles exhibit a localized surface plasmon resonance (LSPR) which is very sensitive to the size and shape of the nanoparticle and the surrounding dielectric medium. The coupling between the electromagnetic radiation and the localized surface plasmon in metallic nanoparticles results in a sizable enhancement of the incident fields, making them possible candidates for plasmonic applications. In particular, partially exposed metallic nanoparticles distributed in a dielectric matrix can provide prime locations for LSPR spectroscopy and sensing. We report the synthesis and characterization of a plasmonic substrate consisting of Ag nanoparticles partially buried in MgO. Ag nanoparticles of different shapes and size distributions were synthesized below the surface of MgO by implanting 200 keV Ag(+) ions followed by annealing at 1000 °C for 10 and 30 h. A detailed optical and structural characterization was carried out to understand the evolution of the Ag nanoparticle and size distribution inside the MgO matrix. Micro x-ray diffraction (Micro-XRD) was employed to investigate the structural properties and estimate the crystallite size. The nanoparticles evolved from a spherical to a faceted morphology with annealing time, assuming an octahedral shape truncated at the (001) planes, as visualized from aberration-corrected transmission electron microscopy (TEM) images. The nanoparticles embedded in MgO were shown to be pure metallic Ag using atom probe tomography (APT). The nanoparticles were partially exposed to the surface by employing plasma etch techniques to remove the overlaying MgO. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were employed to study the surface morphology and obtain a height distribution for the partially exposed nanoparticles.
