Evaluation of antibacterial efficacy of anise wastes against some multidrug resistant bacterial isolates
In this study we investigated the antibacterial and resistance modulatory activity of Aniseeds waste Residue Extract (ASWRE) and Star Anise Waste Residue Extract (SAWRE) (post-distillation) against 100 isolates belonging to two Gram positive (Streptococcus pneumoniae and Staphylococcus aureus) and four Gram negative bacteria (Klebsiella pneumoniae, Escherichia coli, Acinetobacter baumannii and Pseudomonas aeruginosa). Phenolic compounds of anise wastes were determined by HPLC. The antibacterial activity of anise waste extracts assays were performed by using inhibition zone diameters, MIC and MBC. Evaluation of synergy inte...

Synthesis and stability test of radioimmunoconjugate 177Lu-DOTA-F(ab ′)2-trastuzumab for theranostic agent of HER2 positive breast cancer
Publication date: Available online 27 July 2016 Source:Journal of Radiation Research and Applied Sciences Author(s): Sandra Hermanto, Ratna Dini Haryuni, Martalena Ramli, Abdul Mutalib, Sumi Hudiyono The use of trastuzumab as intact IgG labeling radionuclide for HER2 positive breast cancer theranostic agent is not ideal because it is slowly eliminated from the blood and normal tissues resulting in low tumor/blood (T/B) and tumor/normal tissue (T/NT) ratios. To overcome this limitation, we developed the trastuzumab F(ab′)2 fragments and radiolabeling of the fragments by β and γ-particle of Lutetium-177. F(...

Small angle scattering of 59.54  keV photons by elemental samples in the atomic number region 13 ≤ Z ≤ 82
Publication date: January 2016 Source:Journal of Radiation Research and Applied Sciences, Volume 9, Issue 1 Author(s): L. Vinaykumar, T.K. Umesh In the present paper, we report the angle integrated coherent scattering cross sections of some elements at low momentum transfer over four angular ranges for some elements in the atomic number range 13 ≤ Z ≤ 82 for 241Am (59.54 keV) gamma rays. The coherent scattering cross sections were derived from the experimentally measured total (Coherent + incoherent) scattering cross sections for the elements at the energy of interest by subtracting separately the sma...

Assessment of the radioprotective effect of propolis in breast cancer patients undergoing radiotherapy. New perspective for an old honey bee product
Conclusions Supplementation of propolis with radiotherapy treatment offers a quite measurable protection against DNA damage caused by ionizing radiation in BC patients leukocytes and inhibits RRM2 overexpression. Moreover, propolis has beneficial effects on the serum antioxidant capacity and improves the digestive utilization of iron and the regeneration efficiency of hemoglobin. Larger prospective studies are required to confirm our findings. (Source: Journal of Radiation Research and Applied Sciences)

Retina damage after exposure to UVA radiation on the early developmental stages of the Egyptian toad Bufo regularis Reuss
Publication date: Available online 8 June 2016 Source:Journal of Radiation Research and Applied Sciences Author(s): Alaa El-Din H. Sayed, Ekbal T. Wassif, Afaf I. Elballouz The present study was carried out to investigate the histological and histochemical changes in the retina on different developmental stages of Egyptian toad Bufo regularis. Our experiment started when tadpoles begin to feed. The adapted embryos are divided into 3 large tanks of 200 embryos each, collections of samples started from feeding age every three days. Both histological and histochemical results showed that the general architecture of ...

Early age shrinkage pattern of concrete on replacement of fine aggregate with industrial by-product
Publication date: Available online 1 June 2016 Source:Journal of Radiation Research and Applied Sciences Author(s): R.K. Mishra, R.K. Tripathi, Vikas Dubey This is an experimental work carried out to investigate early age shrinkage pattern of concrete, prepared, on 50% replacement of industrial by-product (like pond ash and granulated blast furnace slag) as fine aggregate using OPC, PPC and PSC as a binder. This is to observe the effect of pond ash and slag as they are having some cementitious properties and effect of cement type is also discussed. All the mixes were prepared keeping in view of pumpable concrete ...

Effects of combined exposure to aluminum chloride and γ-radiation on histological and ultrastructure of intestinal Paneth cells
Conclusions It is concluded that concomitant exposure to aluminum and IR increased detrimental structural changes in PC of rat intestine due to their combined effect. It is thus recommended to limit the intake of aluminum when human are at risk of over exposure to ionizing radiation. (Source: Journal of Radiation Research and Applied Sciences)
