Bioaccumulation of Trace Metals in Tissues of Rohu Fish for Environmental Risk Assessment  [PDF]
Nazima Noor, Bela Zutshi
Journal of Water Resource and Protection (JWARP) , 2016, DOI: 10.4236/jwarp.2016.84040
Abstract: In the present study, the two lakes, Vengaiah lake (Lake A-Sewage polluted receiving discharge from storm water drain) and Yellamallappa Chetty lake (Lake B-Industrially polluted) situated near Krishnarajpuram-Hoskote taluk, Bangalore, Karnataka were selected for analysis of trace metals viz., arsenic, aluminium, cadmium, lead, mercury, iron, copper and zinc in water samples. Muscle and gill tissues of freshwater fish Labeo rohita reared in these water bodies were analysed for bioaccumulation of trace metals. Hebbal fish farm was considered as a reference site (Control site) for water and fish samples. Trace metals were analysed by atomic absorption spectroscopy and values were compared with those recommended by FAO/WHO in water and fish samples. Trace metals such as Al, As and Hg were detected in the water sampled from lake B which is attributed to the differences in the sources of pollutants. Fish tissues viz., muscle and gills sampled from Lake B exhibited high concentration of Al, Pb and Cd content showing a positive correlation with their concentration in water samples. The remaining metals as Cu, Zn and Fe were detected in water sampled from all water bodies and also in the fish tissues. Gills exhibited higher concentration of metals in fish from lake B. Bioaccumulation of these trace metals in fish tissues may cause potential danger to human health when consumed on regular basis. Thus necessary remedial measures are required to combat water contamination and its management keeping in view the aquatic ecosystem and public health. Values were statistically significant at P < 0.0001.

Abstract: We present two software packages developed to support detector R&D studies for the International Linear Collider. LCDG4 is a full-detector simulator that provides energy deposits from particles traversing the sensitive volumes of the detector. It has been extensively used within the American ILC community, providing data for algorithm development and detector optimization studies. DigiSim models real-life digitization effects, converting the idealized response into simulated detector readout. It has many useful features to improve the realism in modeling detector response. The main characteristics of these two complementary packages are discussed.
Examination of direct-photon and pion production in proton-nucleon collisions
L. Apanasevich,M. Begel,C. Bromberg,T. Ferbel,G. Ginther,J. Huston,S. E. Kuhlmann,P. Slattery,M. Zielinski,V. Zutshi
Physics , 2000, DOI: 10.1103/PhysRevD.63.014009
Abstract: We present a study of inclusive direct-photon and pion production in hadronic interactions, focusing on a comparison of the ratio of gamma/pi0 yields with expectations from next-to-leading order perturbative QCD (NLO pQCD). We also examine the impact of a phenomenological model involving k_T smearing (which approximates effects of additional soft-gluon emission) on absolute predictions for photon and pion production and their ratio.
Role of hyoscine N-butyl bromide (HBB, buscopan ) as labor analgesic
Aggarwal Pakhee,Zutshi Vijay,Batra Swaraj
Indian Journal of Medical Sciences , 2008,
Abstract: Background: Hyoscine N-butyl bromide (HBB) acts by inhibiting cholinergic transmission in the abdomino-pelvic parasympathetic ganglia, thus relieving spasm in the smooth muscles of gastrointestinal, biliary, urinary tract and female genital organs, especially the cervico-uterine plexus and aiding cervical dilatation. AIM: The study was undertaken to observe the effects of 40 mg intravenous HBB as a labor analgesic and labor accelerant. Settings and Design: This prospective randomized control trial was carried out on 104 primigravidae with single live fetus in cephalic presentation, with spontaneous onset of labor, between 37-40 weeks of gestation. Materials and Methods: Women were consecutively randomized into study (group I) and control (group II) groups, each with 52 patients after excluding high risk factors like preeclampsia, antepartum hemorrhage, previous uterine scar, and any contraindications to vaginal delivery. Group I received 40 mg HBB as a slow intravenous injection in the active phase of labor while Group II received 2mL normal saline. Pain scores were assessed at baseline and two hours later. Secondary outcome measures compared were progress of labor based on injection delivery interval, mode of delivery and neonatal condition at birth. Statistical Analysis: Statistical significance was assessed by using Student′s t-test and Chi-square test. P-value < 0.05 was taken as significant. Results: Pain relief of 35.6% was noted on visual analog score with the use of HBB. Mean duration of labor was 3 hours 46 minutes in Group I compared to 8 hours 16 minutes in Group II (P value: < 0.001). Mode of delivery and neonatal outcome were comparable. No adverse maternal effects were noted. Conclusions: Intravenous Hyoscine N-Butyl Bromide causes pain relief of up to 36% and shortens the duration of active phase without any untoward short term fetal or maternal effects.

Abstract: The design, construction, and preliminary testing of a second generation proton CT scanner is presented. All current treatment planning systems at proton therapy centers use X-ray CT as the primary imaging modality for treatment planning to calculate doses to tumor and healthy tissues. One of the limitations of X-ray CT is in the conversion of X-ray attenuation coefficients to relative (proton) stopping powers, or RSP. This results in more proton range uncertainty, larger target volumes and therefore, more dose to healthy tissues. To help improve this, we present a novel scanner capable of high dose rates, up to 2~MHz, and large area coverage, 20~x~24~cm$^2$, for imaging an adult head phantom and reconstructing more accurate RSP values.

Abstract: Computer tomography is one of the most promising new methods to image abnormal tissues inside the human body. Tomography is also used to position the patient accurately before radiation therapy. Hadron therapy for treating cancer has become one of the most advantageous and safe options. In order to fully utilize the advantages of hadron therapy, there is a necessity of performing radiography with hadrons as well. In this paper we present the development of a proton computed tomography system. Our second-generation proton tomography system consists of two upstream and two downstream trackers made up of fibers as active material and a range detector consisting of plastic scintillators. We present details of the detector system, readout electronics, and data acquisition system as well as the commissioning of the entire system. We also present preliminary results from the test beam of the range detector.

Bhuinder Singh,Abdul Rauf,Zutshi M.L
Indian Journal of Community Medicine , 1985,
Abstract: The anthropometrics profile of 986 school children was studied in Block Ganderbal a€" a rural field practice area of Govt. Medical College Srinagar. The sample comprised of 14 (approx.25%) educational institutions selected randomly. 605(61.36%) were male children and 381 (38.64%) were female children. Their weights, standing heights and mid-arm circumference were recorded and compared with I.C.M.R. estimates. Heights of both the sexes were less than the All India Standards and the difference was statistically significant in females (p<0.05) and highly significant in males (p<0.0005). However, the weight and mid arm circumference estimates in both the sexes were in agreement with I.C.M.R. estimates. Thus although there was evidence of stunted growth, the severity of present episode of malnutrition was less .An attempt has also been made on nutritional grading.
