, carbofuran, carbaryl and heptachlor. There was a statistically significant (p less then 0.05) association between various factors (availability of protective clothing, hiring of labourers, farm land size, expenditure on pesticides and expenditure on treatment, respectively) on intoxication from pesticide exposure.River water is very much important for domestic, agriculture and industrial use in Bangladesh which is in critical condition from long time based on research data. During last 40 years, extreme pollution events occurred in peripheral rivers surrounding Dhaka city and Karnaphuli River in Chittagong city. Present data showed that other urban rivers are also in critical condition especially Korotoa, Teesta, Rupsha, Pashur and Padma. The pollutants flowing with water made a severe pollution in downstream areas of rivers. Metals concentrations in river water was found to be higher in dry season. Dissolve oxygen (DO) was nearly zero in Buriganga River and several points in Turag, Balu, Sitalakhya and Karnaphuli River. NO3-, NO2- and PO43- pollution occurred in different rivers. Zn, Cu, Fe, Pb, Cd, Ni, Mn, As and Cr concentration was above drinking water standard in most of the river and some metals was even above irrigation standard in water from several rivers. Sediment data showed very much higher metal concentrations in most of the rivers especially peripheral rivers in Dhaka and Karnaphuli, Korotoa, Teesta, Rupsha and Meghna River. selleck products Metal concentrations in sediment was above US EPA threshold value in most of the rivers. Metal concentrations in fish and agricultural crops showed that bioaccumulations of metals had occurred. The concentration of metals showed the trend like water less then fish less then sediment. Agricultural crops were found to contain toxic metals through polluted water irrigation. The calculated data of daily intake for the non-carcinogenic and carcinogenic showed that consumption of the contaminated foodstuff can cause serious health injuries.
Monte Carlo (MC) modelling techniques have been used extensively in Nuclear Medicine (NM). The theoretical energy resolution relationship (

), does not accurately predict the gamma camera detector response across all energies. This study aimed to validate the accuracy of an energy resolution model for the SIMIND MC simulation code emulating the Siemens Symbia T16 dual-head gamma camera.

Measured intrinsic energy resolution data (full width half maximum (FWHM) values), for Ba-133, Lu-177, Am-241, Ga-67, Tc-99m, I-123, I-131 and F-18 sources in air, were used to create a

The results showed the
underestimated the FWHM values at energies above 160.0 keV up to 23. model enables the SIMIND user to accurately simulate NM images. A great improvement was seen for high-energy photon emitting isotopes (e.g. I-131), as well as isotopes with multiple photopeaks (e.g. Lu-177, I-131 and Ga-67) in comparison to the theoretical model. This will result in accurate evaluation of radioactivity quantification, which is vital for dosimetric purposes.Dioctophyme renale is the largest parasitic nematode of animals. It is most often found in the right kidney, but can also occur in the urinary system, ears, free abdominal cavity, mammary gland, thoracic cavity, and more rarely in subcutaneous tissue. The genus Dirofilaria has specific parasitic characteristics according to its location, and may parasitize the respiratory tract or even the skin, varying according to species. This report describes a case of Dioctophyme renale and Dirofilaria sp. in the subcutaneous tissue of a cat in the state of Espírito Santo, Brazil. An adult male mongrel cat showed physical enlargement in the left inguinal region, diagnosed as a subcutaneous nodule. Surgical excision and histopathological evaluation of the nodule were performed, and Dioctophyme renale and Dirofilaria sp. were found inside. Dioctophymosis and heartworm disease are present in Brazil and most other countries, but this is the unprecedented case of the association of Dioctophyme renale and Dirofilaria sp. in the subcutaneous tissue of a cat.Huntington's disease is a neurodegenerative disease caused by CAG repeat in the first exon of HTT (Huntingtin) gene, leading to abnormal form of Htt protein containing enlarged polyglutamine strands of variable length that stick together to form aggregates and is toxic to brain causing brain damage. Complete reversal of brain damage is not possible till date but recovery may be possible by peptide therapy. The peptide-based therapy for Huntington's disease includes both poly Q peptide as well as non poly Q peptides like (QBP1)2, p42, Exendin 4, ED11, CaM, BiP, Leuprorelin peptide. The novel approach that is currently being tested in this article is the peptide-based therapy to target the mutated protein. This approach is based on the principle of preventing the aggregation of mutant Htt by blocking the potential sites responsible for protein aggregation and thereby ameliorating the disease symptoms. Herein, we have screened a variety of potential peptides that were known to prevent the protein aggregation, comparatively analyzed their binding affinity with homology modeled Htt protein, designed novel peptides based upon conservation analysis among screened potential peptides as a therapeutic agent, comparatively analyzed the therapeutic potential of novel peptides against modeled Htt protein for investigating the therapeutic prospects of Huntington's disease. We have designed a peptide for the therapy of Huntington's disease by comparing several peptides, which are already in use for Huntington's disease.In the present study, six water samples were collected from different locations in the Kingdom of Saudi Arabia and another sample from the Zamzam site in Makkah city. The concentration of the radioactive isotope 222Rn was measured using the electronic radon detector (RAD7). The comparative analysis study on these samples showed that the average concentration value in all samples was 0.504Bq/L. The data analysis showed that the concentration of 222Rn was ranged from 0.43 ± 0.06 Bq/L to 0.57 ± 0.060 Bq/L for all samples. These levels are below the contamination threshold (11.1 Bq/L) recommended by the US Environmental Protection Agency (EPA). Interestingly, Radon radioactivity levels were lower than those harmful to human health. The principal component analysis (PCA) using (SPSS version 15) was used to reduce the four variables influencing the 222Rn activity concentration to two variables temperature (correlation coefficient, R2 0.984) and the relative humidity (RH%) (R2-0.987). The increase in temperature reduces the solubility of 222Rn gas activity water and facilitates its detection, whereas increased the RH% increases its solubility and decreases the detection level of 222Rn activity concentration.
