Performance of irrigation projects and their impacts on poverty reduction and its empowerment in arid environment

Biophysical and socioeconomic conditions of pre and post dam construction were assessed in one of the arid regions of Iran commanded by Minab dam. The methodology used in this study was drawn from the international organizations especially the World Commission on Dams and the United Nations for selection of the indicators for sustainable development relating to water resources projects. Commissioning of the dam in 1986 led to progressive expansion of the irrigated agriculture, which was almost doubled in year 2006. Results of the study revealed that there is significant positive impact of the irrigation infrastructures of the dam; for example literacy rate has increased from 41% [pre project] to 74% in 2006. Similarly, significant improvements were observed in health care, sanitation, education and other scopes. Nevertheless, for some of the targets only 50-60% progress were made, whereas no significant achievements had been made in the others. Therefore, development did not match with the planned goals of the project. Deficiency in achieving the primary objectives, especially after many years of project completion, may be attributed to the management and implementation of the project. For effective project performance, a new institutional framework and guide lines are proposed in this article

Determination of the specificities of monoclonal and polyclonal antibodies to Neospora, Toxoplasma and Cryptosporidium by fluorescent antibody test (FAT)

Flourescent antibody test (FAT) was applied to determine the cross-reactivities of monoclonal (mAb), polyclonal (pAb) antibodies to Neospora, Toxoplasma and Cryptosporidium and antisera from cattle naturally infected with Neospora canium against antigens from a number of sources. Both mAb and pAb to Neospora reacted strongly (FAT titre up to 2560) with the homologous antigens and demonstrated weak titre (80) or no reaction with both Toxoplasma and Cryptosporidium antigens. Also mAb and pAb to Toxoplasma gondii reacted at titres of 80 - 640 with homologous antigens and at titres of 10-40 with N. caninum. No cross-reactions with either mAb or pAb antibodies to N. caninum and T. gondii were observed with Cryptosporidium parvum. The same results were observed with C. parvum mAb when tested with both N. caninum and T. gondii antigens. Sera from cattle naturally infected with N. caninum had titres ranging from 80- 640 with N. caninum antigens, and 10- 40 with T. gondii and C. parvum antigens. At low dilutions, the complete surfaces of Neospora and Toxoplasma parasites were fluorescent, while in higher dilutions only dotted fluorescence appeared on the apical complex. These results indicated the presence of cross-reactivity between Neospora and Toxoplasma but not with Cryptosporidium. Accordingly the recommended cut-off antibody titre for diagnosis of neosporosis is 80.

Atrial fibrillation in mitral stenosis and its correlation with age, sex and clinical symptoms

The objective of the study was to calculate the frequency of atrial fibrillation of MS and its correlation with age, sex and clinical symptoms. A prospective descriptive study. Mayo Hospital and Punjab Institute of Cardiology, Lahore. 112 patients of mitral stenosis were investigated with an ECG and an echocardiography to confirm mitral stenosis and to measure anteroposterior left atrial dimensions on M-mode. All patients who were suffering from AF due to causes other than mitral stenosis were excluded. The significance of findings were tested through standard "t"test. Atrial fibrillation is more in female patient and has a linear correlation with age. More common symptoms of shortness of breath followed by palpitation
