Relationship between Calcium-Phosphorus Product and Severity of Valvular Heart Insufficiency in Patients Undergoing Chronic Hemodialysis
Masoumeh Kahnooji,Mohammad Masoomi,Ali Naderinasab,Akram Zaeem
Journal of Tehran University Heart Center , 2010,
Abstract: Background: Recent interests have mainly focused on the roles of serum calcium and phosphorus and their product (Ca-P product) in the development of valvular heart disease. The present study assessed the relationship between the Ca-P product and the severity of valvular heart disease in end-stage renal disease (ESRD) patients undergoing chronic hemodialysis.Methods: This cross-sectional study reviewed the clinical course of 72 consecutive patients with the final diagnosis of ESRD candidated for chronic hemodialysis. The severity of valvular heart disease was determined using M-mode two-dimensional echocardiography. The serum calcium and phosphate values adopted were those values measured on the day between the two consecutive dialyses, and the Ca-P product was calculated.Results: The most common causes of ESRD were diabetic nephropathy, malignant hypertension, and chronic glomerulonephritis. The mean Ca-P product level in the dialysis patients was 50.44 ± 17.78 mg2/dL2. The receiver-operator characteristic (ROC) curve illustrated that a Ca-P product level > 42 mg2/dL2 was the optimal value in terms of sensitivity and specificity for predicting the presence of valvular insufficiency. Aortic insufficiency was directly associated with a high Ca-P product value after adjustment for age, gender, serum albumin, diabetes, hypertension, hyperlipidemia, coronary artery disease, and serum creatinine (β = 0.412, SE = 158, p value= 0.011).Conclusion: A positive relationship between the Ca-P product value and the severity of aortic insufficiency is expected. Achieving an appropriate control of the Ca-P product level may decrease aortic valve calcification and improve the survival of patients on chronic hemodialysis.
Knowledge and communication needs assessment of community health workers in a developing country: a qualitative study
Zaeem Haq, Assad Hafeez
Human Resources for Health , 2009, DOI: 10.1186/1478-4491-7-59
Abstract: Focus group discussions were held with health workers and their supervisors belonging to all the four provinces of the country and the Azad Jammu & Kashmir region. Self-response questionnaires were also used to obtain information on questions regarding their continued education.About four fifths of the respondents described their communication skills as moderately sufficient and wanted improvement. Knowledge on emerging health issues was insufficient and the respondents showed willingness to participate in their continued education. Media campaigns were successful in building the image of health workers as a credible source of health information.A continued process should be ensured to provide opportunities to health workers to update their knowledge, sharpen communication skills and bring credibility to their persona as health educators.Primary Health Care (PHC) defined as "Essential health care made universally accessible to individuals and families in the community by means acceptable to them, through their full participation, and at a cost that community and country can afford" has been recommended as a set of health services that can meet the challenges of a changing world [1]. The World Health Organization (WHO) in its latest report has called for a revival of PHC [2].An important component of the rejuvenated concept of PHC is community health workers, (CHWs) who act as a bridge between the health care delivery system and the community. Mary & Rosemary have described how CHWs enable health programmes to achieve three interconnected goals: building a relationship between the health care provider and laypersons in the community; improving appropriate health care utilization; and educating people to reduce health risks in their lives [3]. Highly challenging and innovative ideas such as serving 70% of a population of 190 million in Brazil, skin-to-skin care for newborns in India and improved perinatal care in Nepal have worked remarkably well through CHWs [4-6].Ap
Graph Sensitive Indices for Comparing Clusterings
Zaeem Hussain,Marina Meila
Computer Science , 2014,
Abstract: This report discusses two new indices for comparing clusterings of a set of points. The motivation for looking at new ways for comparing clusterings stems from the fact that the existing clustering indices are based on set cardinality alone and do not consider the positions of data points. The new indices, namely, the Random Walk index (RWI) and Variation of Information with Neighbors (VIN), are both inspired by the clustering metric Variation of Information (VI). VI possesses some interesting theoretical properties which are also desirable in a metric for comparing clusterings. We define our indices and discuss some of their explored properties which appear relevant for a clustering index. We also include the results of these indices on clusterings of some example data sets.

Alaa Al-Deen Al-Dabbagh, Zaeem Fezea Dahla
Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.812036
Abstract: Background: Male urethral stricture is as yet considered one of the very popular and defying dilemmas to the urologist. Treatment modalities include dilation, endoscopic urethrotomy and urethroplasty, however internal optical urethrotomy displays rapid cure, lower scarring, and minimal hazard of infection. Purpose: To evaluate the efficacy of internal optical urethrotomy in the treatment of patients with urethral stricture. Patients & Methods: This study was carried out at Al-Yermouk Teaching Hospital/Baghdad/Iraq in the period between January 2015 and January 2018. A group of 75 male patients (16 - 25 years of age) presented with urethral strictures had been treated with internal optical urethrotomy. Follow-up period ranged from 1 - 3 months. Outcome was graded as good, fair and poor. Results: Out of 75 patients, 28 (37.3%) were (21 - 30) years of age. Trauma was the most popular source of stricture found in 40 (53.3%) and the most widespread presenting feature was poor urinary flow in 32 (42.6%) patients. Stricture in the bulbous urethra in 48 (64%) cases was found to be the most prevalent area followed by penile urethra in 16 (21.3%) cases. Overall response rate was good in 52 (69.3%) patients. Eleven (14.6%) patients exhibited only minor bleeding postoperatively with no other considerable complications. Conclusion: Internal optical urethrotomy is a dependable and effective procedure in treating urethral stricture.
ASIP Solution for Implementation of H.264 Multi Resolution Motion Estimation  [PDF]
Fethi Tlili, Akram Ghorbel
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2010, DOI: 10.4236/ijcns.2010.35060
Abstract: Motion estimation is the most important module in H.264 video encoding algorithm since it offer the best compression ratio compared to intra prediction and entropy encoding. However, using the allowed features for inter prediction such as variable block size matching, multi-reference frames and fractional pel search needs a lot of computation cycles. For this purpose, we propose in this paper an Application Specific Instruction-set Processor (ASIP) solution for implementing inter prediction. An exhaustive full and fractional pel combined with variable block size matching search are used. The solution, implemented in FPGA, offers both performance and flexibility to the user to reconfigure the search algorithm.
Spatio-Temporal Land Cover Dynamics in Open Cast Coal Mine Area of Singrauli, M.P., India  [PDF]
Imran Khan, Akram Javed
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.46057
Abstract: Singrauli is an opencast coal mining area where large scale mining activities are going on continuously, land use/land cover studies are of vital importance to observe the changes in the land use/land cover. The present study utilizes multi-spectral/multi-temporal data of Indian Remote Sensing Satellite (IRS) LISS II geocoded (FCC) of 4th May 1993 and LISS III of 4th May 2010 for thematic mapping. Survey of India toposheet 63L/12 on scale 1:50,000 were used for preparation of base map which was overlaid on the FCC for land use/land cover mapping through visual interpretation. Visual interpretation of satellite imagery led to the identification of 15 land use/land cover categories such as dense forest, open forest, open scrub, plantation, cultivated land, uncultivated land, mining pit, overburden dumps, wasteland and settlement. The ground truth verification was carried out in key areas to rectify the errors in generated maps and then land use/land cover maps were finalized. The comparative analysis of land use/land cover shows that dense forest has been degraded to open forest, open scrubs and mining pits due to the expansion of mining activity. Open scrubs has increased, overburden dumps has increased, settlement has also increased, cultivated land has decreased and changed into uncultivated land and wasteland. It has also been observed that the plantation has been done on overburden dumps and residential colonies of NCL and NTPC. It has been identified that the main drivers which has increased the rate of change in land use/land cover are mainly coal mining activities and industrial expansion.
Identification of Artificial Recharge Sites in Manchi Basin, Eastern Rajasthan (India) Using Remote Sensing and GIS Techniques  [PDF]
Subah Rais, Akram Javed
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62017
Abstract:

The present study is an attempt to prepare a water resource development action plan for Manchi basin in Eastern Rajasthan (India) using remote sensing and GIS techniques. Satellite data have proven to be very useful for surface study, especially in the preparation of land use/land cover and geomorphological map. Morphometric parameters are analyzed to understand the basin characteristics and its influence on the water resources for instance bifurcation ratio indicates high surface run off and low recharge in SB-I, IV, V. Low drainage density ranges from 2.41 (SB-IV) to 2.99 (SB-V) km/km2, with an average of 2.72 km/km2 showing permeable strata, dense vegetation and low relief. Analysis of shape parameters i.e. elongation ratio and circularity ratio suggest that Manchi basin is elongated in shape. Whereas, slope, geology and geomorphological mapping is done to demarcate groundwater potential zones for future exploration in the study area. Slope is inversely proportional to infiltration. Therefore, sub-basin areas having gentle slope permits less runoff and more infiltration as in alluvial plains and vice versa where hills and ridges are present. The integrated study helps in designing suitable sites for constructing water harvesting structures. Check dams, percolation tanks and nala bund are proposed at 1st, 2nd or 3rd drainage orders at SB-I and SB-IV with ravenous land (open scrub), uncultivated land, open forest & exposed rock present. Nala bund & check dam are proposed at SB-II & SB-V whereas, at SB-III check dams & percolation tanks are proposed so as to conserve the natural resources present in the basin. Finally, the best feasible water harvesting structures have been proposed within the sub-basins area using remote sensing and GIS techniques.

Akram Shahhosseini, Leila Hosseina
Open Journal of Geology (OJG) , 2016, DOI: 10.4236/ojg.2016.66042
Abstract: Our study area “Tafresh” is located in the sedimentary-volcanic belt. This work was carried out as systematic for surveying ore potentials at Tafresh base on the geology, geochemistry, laboratories studies, remote sensing, and tectonic. According to study of 109 samples, most of the area’s mineralization has been associated with Dacite, Diorite, Tonalite intrusive massive, Andesitic dykes which are related to operation of thrust and strike slip faults. Also, most of these ore deposits had been concentrated at sedimentary rocks of Cretaceous that involves Limestone and Shale in the Southwest and Andesite to Andesitic Basalt at the Northern of Tafresh area. Most of the alterations zones associated with mineralization are androgenic like Argillic, Propylitic, Sericitic, and siliceous alterations that have appropriate adaptation with area’s major faults as well. Eventually, based on the geochemical studies and incorporating all data by GIS software, Tafresh has remarkable concentration of Cu and Au ore deposits that are recognized as Skarn and Hydrothermal ore deposits which are related to fluids flowing from intrusive massive and dykes.

Journal of Power and Energy Engineering (JPEE) , 2016, DOI: 10.4236/jpee.2016.49002
Abstract: Libya is an oil exporting country located in the middle of the North Africa. Exporting oil is the major income resource for the economics of the country. Al-Zawea refinery is one of the oil refineries in Libya. It is the largest refinery in the region. The refinery located in the Mediterranean coast. Electricity is the main sector in the refinery to produce and export oil. This paper discusses the possibility of the penetration of the renewable energy (wind) generated electricity into the refinery power system. Although, renewable energy application in Libya was started in the middle of the seventies, it has still not found its way into industry sector. This study proposes the possible impacts of renewable (wind) energy system integration on the Al-Zawea refinery electric grid to satisfy the refinery load demand.
Cancer Specific Non-Synonymous Single Nucleotide Polymorphism Prediction in the Context of Haplotype and Protein Interacting Sites  [PDF]
Pakeeza Akram, Li Liao
Journal of Biomedical Science and Engineering (JBiSE) , 2017, DOI: 10.4236/jbise.2017.105B004
Abstract:
In this work, we study predicting the effect of non-synonymous SNPs on several cancers. We trained classifiers on both sequential and structural features extracted from the affected genes and assessed the predictions made by the trained classifiers using cross validation. Specifically, we investigated how the prediction performance can be improved by connecting SNPs in the context of haplotype and interacting sites of proteins encoded by affected genes. We found that accuracy was consistently enhanced by combining sequential and structural features, with increase ranging from a few percentage points up to more than 20 percentage points. The results for putting SNPs in the context of interacting sites were less consistent. Compared to individual SNPs, these that appear together in haplotype showed stronger correlation with one another and with the phenotype, and therefore led to significant improvement inprediction performance, with ROC score increased from 0.81 to 0.95. Although some similar effect has been expected for connecting SNPs to interacting sites in proteins, the performance actually got worse. This decrease in prediction accuracy may be caused by the small data set being used in the study, as many affected proteins in the study do not have known interacting sites.
