Contamination of Air, Soil and Water, As Evaluated on the Basis of Lead Contents in the Vicinity of Various Lakes and Dams within Pakistan
Abbas Khan,M. Jaffar
Journal of Applied Sciences , 2002,
Abstract: In order to study the lead levels in air, soil and water in the vicinity of various Lakes and Dams within the Pakistan, Samples were collected periodically from the selected sites for the three media, and were analyzed by AAS. This investigation on Lakes and relevant air / soil / water showed that maximum concentration of Pb were 717.5 μg/M3, 44.9 mg/ kg and 217 μg/L in air, soil and water respectively. Analysis based on statistical parameters evidenced a positive correlation between air- soil, air- water and soil- water systems. The values of X and G.M, emphasized a randomize distribution of Pb contents in the three media. Elevated Pb levels were determined at Khan Pur Dam in case of air and water system, while at Rawal lake in case of soil samples. Quaid-i-Azam University Lake was found free from Pb because Pb levels were below detection limits i.e. not detectable in case of water.
Lead Contamination of Air, Soil and Water in the Vicinty of Rawal Lake, Islamabad
Abbas Khan,M. Jaffar
Journal of Applied Sciences , 2002,
Abstract: The levels of lead in the air, soil and water of Rawal Lake and its vicinity has been determined during the temporal study. The measurement of Pb in air, soil and water appears to be a useful tool for evaluating the potential hazards of the environment. The AA technique was applied for these estimations conducted on 93 samples, 31 of each (air, soil and water) procured from the Rawal Lake. The study revealed that the range of concentration of Pb was around 33.3 to 338.7 μg/m3 in air, 0.6-21.2 mg/kg in soil and BDL to 170 μg/L in water. Standard deviation and geometric mean values elaborate the more random character fair, followed by water and their soil. The data collected shows that almost all the pollution is being generated by automobile exhaust and also that soil and water act as important sink for Pb released through different activities.
Myocardial Ischemia Following Shrapnel Epicardiac Injury 16 Years Earlier: Case Report  [PDF]
Jaffar S. Shehatha, Dara M. Mohialdeen, Abdulsalam Y. Taha, Abdulsalam Y. Taha

Abstract:

Coronary artery injuries are uncommon. Acute injuries of major coronary vessels, particularly the left anterior descending artery (LAD), are life-threatening because of the significant cardiac dysfunction that ensues and usually requires repair or bypass. In contrast, late presentation of missile coronary artery injuries has been sporadically reported in the literature. Herein we present a 32-year-old lady from Sulaimania, Iraq with multiple shrapnel injuries 16 years earlier presented recently with severe anterolateral myocardial ischemia unresponsive to medical treatment. Coronary angiography and surgical exploration revealed shrapnel compressing the LAD. The patient responded very well to shrapnel extraction and coronary artery revascularization (off pump left internal mammary artery—LIMA—to LAD anastomosis). The management of this patient is discussed with review of relevant literature. It is concluded that long-standing shrapnel close to a major coronary artery may incur an external trauma initiating a localized arteriosclerosis with an extremely long time interval from injury to the onset of symptoms of myocardial ischemia.


Relationship Study between the Alkaline Protease Production and the Growth Phases of Pseudomonas aeruginosa Isolated from Patients  [PDF]

Advances in Microbiology (AiM) , 2012, DOI: 10.4236/aim.2012.23043
Abstract: This study was conducted in Diyala University Laboratories collaboration with the Directorate of Diyala Health. Occurrence of Pseudomonas aeruginosa was investigated in 161 samples from different clinical sources included Swabs from wounds, burns, ear, eye and samples from Urine and sputum which were collected from patients. Depending on the cultural and micro features and biochemical tests 49 isolated items of this bacteria have been diagnosed and all the isolates showed the proteolytic activity by using skim milk agar through forming clear zone around the growing colonies, and tested the isolates ability of alkaline protease production by quantitative methods, the local isolation P. aeruginosa AP3 had been selected based on the higher productivity of enzyme comparing to other isolates and thus it was used in the current study. Studied the relationship between the production of alkaline protease enzymes and growth phases of P. aeruginosa to determine the time of the enzyme production and the results showed that the local isolation P. aeruginosa AP3 began production of the enzyme in the later stages of the log phase and increased production significantly in the stationary phase reaching amaximum after 48 hours as estimated the enzyme activity 159.2 units/ml in the farm leaky and keep the enzyme fully functional almost in the stationary phase.

Engineering and Tectonic Study of Rocks Discontinuities in the Proposed Abo-Hederya Quarry Site, Missan SE Iraq  [PDF]
Jaffar H. A. Al-Zubaydi, Abdulkadhim J. Alabidi, Ali M. H. Al-Janabi, Nadhir Al-Ansari
Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.88049
Abstract: A detailed field survey of discontinuity (fractures) was carried out in the proposed Abo-Hederya Quarry Site, 70 km east Missan city, south-east of Iraq, where Al-Mukdadiya Formation (Upper Miocene-Pliocene) is exposed. The discontinuity survey was carried out in 10 stations covering the study area. At each station notes were collected about beds (lithology, thickness and orientation) and discontinuities (orientation, density, spacing, persistence and aperture). The slope stability analysis suggests that there is no real hazard area that could affect the quarry in future. Tectonic analysis demonstrates that tension fractures are common in the study area, while shear fractures (okl, hko, hol and hkl) are the less. The maximum principal stress direction in the study area is N (15 - 40) E, which is compatible with the regional tectonic stress in the area.

African Journal of Biotechnology , 2008,
Abstract: Bacterial blight (BB) caused by Xanthomonas oryzae pv oryzae (Xoo) is a major biotic constraint in the irrigated rice belts. Genetic resistance is the most effective and economical control for bacterial blight. Molecular survey was conducted to identify the rice germplasm/lines for the presence of Xa4, a bacterial blight resistance gene. PCR with primers specific for Xa4 resistances gene was used in the study. During this polymorphic survey, out of 100 rice germplasm lines obtained from NARC (IABGR), 49 lines were observed with Xa4 gene. While 51 germplasm showed the absence of Xa4 gene. Of the nineteen basmati breeding lines, obtained from Rice Research Station Kala Shah Kaku (KSK RRI), 7 lines (KSK1, KSK4, KSK6, KSK7, KSK8, KSK12 and KSK16) showed the presence of Xa4 gene. The Pakistani released Basmati varieties were also surveyed. Of the eight Pakistani basmati varieties used, Basmati 198, Basmati 385, Basmati 2000 and Shaheen Basmati have the Xa4 gene. The identification of Xa4 gene in Pakistani rice germplasm will help in accelerating the elite breeding program in future, including pyramiding of different disease resistant genes in basmati varieties.

Abstract:

The history of medicine and surgery is a rich source of interesting stories of genius and brave people who paved the way ahead of mankind towards the current status of medical and surgical practice. One has to admire the enthusiasms and courage of such people to whom millions of patients ought to be grateful. This paper reports the inspiring stories of 3 heart surgeons (Werner Forssmann, Dr. Lillehei and Dr. Michael E. DeBakey) and highlights their outstanding contributions to the modern cardiac surgery. It reminds the people to remember these three pioneers forever and encourages people working in this field to seek innovation.

Surgery for Aneurysmal Right Coronary Fistula and Constrictive Pericarditis in an Adult: Case Report  [PDF]
Jaffar S. Shehatha, Abdulsalam Y. Taha
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.33041
Abstract:

Coronary artery fistula (CAF) is a direct communication between a coronary artery and the lumen of any of the cardiac chambers, i.e. the coronary sinus, the pulmonary artery, the superior vena cava or the proximal pulmonary veins. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. Congenital CAF is a rare anomaly and aneurysmal formation in the fistula is even rarer. Majority of CAFs are isolated lesions, however, congenital or acquired heart diseases may co-exist. Herein, we report a case of huge congenital aneurysmal right CAF connected to the right atrium in an Iraqi man of 62 associated with tuberculous effusive-constrictive pericarditis to whom off pump pericardiectomy was performed followed by ligation of right coronary artery and vein graft implantation to its posterior descending branch under cardiopulmonary bypass. To the best of our knowledge, such association was not previously reported. CAF can be repaired surgically with minimum risk and excellent outcome. Surgery is advised whenever coronary fistula is diagnosed unless it is very small to avoid the potential complications.
