Shehata, M. R., M. M. Shoukry, A. A. Osman, and A. T. AbedelKarim, "Speciation Studies on the Complex Formation Reactions of [Pd(N,N-diethyl-Ethylendiamine) (H2O)2]2+ with some Bio-relevant Ligands and Displacement Reaction by Mercaptoethylamine", Spectchim. Acta (A)., 2011. Abstract

Pd(deen)Cl2 and Pd(deen)(CBDCA) complexes, where deen = N,Ndiethylethylenediamine and CBDCA= 1,1-cyclobutanedicarboxylate, were synthesized and characterized by elemental analysis and spectroscopic techniques. The stoichiometry and stability of the complexes formed between various biologically relevant ligands (amino acids, peptides, DNA constituents and dicarboxylic acids) and [Pd(deen)(H2O)2]2+ were investigated at 25 ?C and 0.1 M ionic strength. The speciation diagrams of the complexes formed in solutions are evaluated. The mode of coordination of glycylglycine is investigated by spectrophotometric measurements. The equilibrium constants for the displacement of coordinated ligands as inosine, glycine or methionine by mercaptoethylamine are calculated. The results are expected to contribute to the chemistry of antitumour agents.

Kuchai, J. A., M. Z. Chishti, M. M. Zaki, D. M. S. A. Rasool, J. Ahmad, and H. Tak, "Some Epidemiological Aspects of Fascioliasis Among Cattle of Ladakh", Global Veterinaria, vol. 7, issue 4, pp. 342-346, 2011. AbstractCU-PDF.pdf

A total of 208 cattle were randomly selected among slaughter houses, household and livestock farms to determine the prevalence of fascioliasis. Epidemiological studies on fascioliasis of cattle were undertaken in such localities under different climatic conditions existing in Ladakh region of Jammu and Kashmir State. Infection rate was 51.42%, 27.69% and 21.91% in slaughtered, livestock farm and household cattle, respectively. Significant variations were observed in the prevalence with respect to various host factors and the climate of the study area. Overall, the highest seasonal prevalence (45.19%) in all types of cattle was recorded during wet season while as only (24.40%) was recorded during the dry season. It was noticed that a higher infection rate was recorded in young cattle ages (0- 2 years) (40.02%) than in adult ones (28.04%) (3- 8 years). Moreover, the prevalence of infection in females was more (38.07%) than males (29.09%). It was also observed that the infection rate was high in comparatively low land areas (37.14%) as compared to high altitudes (30.09%). This study will provide necessary information regarding fascioliasis in cattle of Ladakh for their effective control and hence for a better production which will be beneficial resource to poor people where live stock rearing is one of the important sources of livelihood.

Ali, F. M., R. E. H. Gebaly, M. E. A. Hag, and A. M. Rohaim, "Solid Ehrlich Tumor Growth Treatment by Magnetic Waves", Technology and Health Care, vol. 19, issue 6, pp. 455-67, 2011. AbstractCU-PDF.pdf

In this work the retardation of Ehrlich tumor growth implanted in mice was studied by employing 4.5 Hz magnetic field. Eighty female Balb/c mice were used, twenty as normal group; the other sixty mice were inoculated with Ehrlich tumor, then they were divided equally into three groups namely A, B and C.Group A (control group) animals were not exposed to the magnetic field .The tumors in the thigh of the animals of group B were exposed to 4.5 Hz, 2 Gauss square wave magnetic field by using a small solenoid connected to a power square wave generator. Group C animals were whole body exposed inside a large solenoid to 4.5 Hz, 2 Gauss square wave magnetic field.Both groups B & C were exposed for a period of 2 weeks at a rate 2 hours per day. Tumor volume, survival period, histological examination and dielectric relaxation of the tumor were measured to investigate the activity of the tumor of the exposed and the unexposed animals. The results indicated that exposing the tumor tissue to 4.5 Hz square wave magnetic field for 2 weeks at a rate 2 hours/day inhibited tumor growth and increased the survival period of the animals. However, group B showed more improvements than did group C. This was attributed to some distortions in the square waveform in the large solenoid (group C). By comparing data from current and previous work, it was concluded that the use of magnetic waves showed better results over previously published work using amplitude modulated electromagnetic waves with the same frequency.

Shim, "Simultaneous Multiresidue Determination Of 48 Pesticides in Yeongsan and Sumjin River water using GC-NPD and Confirmation via GC-MS", Biomedical Chromatography, 2011. Abstract

In a continuation of our earlier work, a multiresidual analytical method using 48 frequently used neutral pesticides in a water matrix was developed and validated in this study. The samples were extracted with dichloromethane and the pesticides were analyzed via GC-NPD followed by confirmation with GC-MS. Good linearity was detected over a concentration range of 0.01-1.0 microg/mL with correlation coefficients (r(2) ) in excess of 0.982. The recoveries were measured between 70.7 and 111.4% for the majority of the targeted pesticides with relative standard deviations (RSDs) of less than 20%. The LODs and LOQs were in ranges of 0.1-2 and 0.33-6.6 microg/L, respectively. A total of 66 water samples were collected from different locations in Yeongsan and the Sumjin River, Republic of Korea, and were analyzed in accordance with the developed method. None of the water samples were determined to contain any of the targeted pesticides. The method has been shown to be simpler, faster, and more cost-effective than the method established by the Environmental Protection Agency (EPA).

Mabrouk, W. M., and M. H. Kamel, "Shale Volume Determination Using Sonic, Density and Neutron Data", Exploration Geophysics, 2011. Abstract

The volume of shale calculation based on naturally occurring gamma ray frequently overestimates shale volume when radioactive material other than shale is present, for example where sand appears to be shale. In this situation, shale volume calculations from other methods are highly recommended in order to avoid overestimation or underestimation of shale volume.

Serum taurine levels were measured in fifty women selected from a wide number of patients presented with irregular uterine bleeding (IUB) to the outpatient clinic of the Obstetrics and Gynecology Hospital, Ain Shams University. No significant differences in age and menopausal status were found. The control group comprised ten healthy women that enrolled as volunteers. According to the findings observed after full clinical examination, ultrasonography, endometrial biopsy or fractional uterine curetting and tumor marker (CA-125) determination, 15 women were diagnosed with endometrial cancer (EC), 10 with cystic endometrial hyperplasia (CEH), 15 with fibromyoma, and 10 women were diagnosed as dysfunctional uterine bleeding (DUB). The results showed non-significant (P > 0.05) changes in the levels of CA-125 in all patients except in the cancer group where it exhibited a value nearly double that of normal (P < 0.01). Serum taurine levels exhibited values lower than control with 8 %, 14 %, 32 % and 56 % in the serum of patients diagnosed as DUB (P > 0.05), fibromyoma (P > 0.05), CEH (P < 0.01) and EC (P < 0.01) respectively.

Toxoplasma gondii and Bartonella spp. are zoonotic pathogens of cats. Feline immunodeficiency virus (FIV) and feline leukemia virus (Fel.v) are related to human immunodeficiency virus and human leukemia virus, respectively, and these viruses are immunosuppressive. In the present study, the prevalence of antibodies to T. gondii, Bartonella spp., FIV, as well as Fel,v and Dirofilaria immitis antigens was determined in sera from feral cats tFelis catusi from Cairo, Egypt. Using a modified agglutination test, antibodies to T. gondii were found in 172 (95.5%) of the 180 cats with titers of]:5 in 9, 1:10 in 9, I :20 in 3, 1:40 in 5, ]:80 in 5, I: 160 in 15, I :320 in 22, and] :640 or higher in 104. Thus, 57.4% had high T. gondii titers. Antibodies to Bartonella spp. were found in 105 (59.6%) of 178, with titers of 1:64 in 45, 1:128 in 39,1:256 in 13, 1:512 in 3,1:1,024 in 4, and 1:2,048 in I cat. Antibodies to FIV were detected in 59 (33.9%) of 174 cats. Of 174 cats tested, antigens to FeLv, and D. immitis were detected in 8 (4.6%) and 6 (3.4%) cats, respectively. The results indicate a high prevalence of T. gondii, Bartonella spp .. and FlV infections in cats from Cairo, Egypt. This is the first report or Bartonella spp., and D. immitis infection in cats in Egypt.
