Background: Vascular access (VA) is the life line for end stage renal disease (ESRD). Though there are many methods of VA, native arteriovenous fistula (AVF) is the oldest and the best. AVFs are prone to develop some complications. The aim of this combined prospective and retrospective clinical study was to assess the outcome of native haemodialysis AVF in Baghdad Medical City Teaching Hospital, Baghdad, Iraq. Materials and Methods: Sixty-seven patients (43 males and 24 females) with ESRD were studied over 6 months, from April 1 to September 30, 2013. Demographic and clinical features as well as co-morbidities were checked. allen’s test and examination of upper limb superficial veins were performed. Radio-cephalic or brachio-cephalic AVFs were created mostly under local anaesthesia using artery-side to vein-end anastamoses. Complications were noted during a follow-up period of 2 weeks to 6 months. Results: The mean age was 51.2 ± 14.4 years. Fistulas (n = 81) were mostly brachio-cephalic (n = 74, 91.4%). One fifth of patients were diabetics and 58.2% were hypertensive. End of the vein to side of the artery was used in 92.5%. all fistulae functioned primarily. Significant complications were thrombosis (n = 18, 22.2%), aneurysms (n = 3, 4.5%) and steal syndrome (n = 3, 13.6%). Distal oedema, venous congestion, wound infection and seroma were managed conservatively. Three surgical revisions were required, one for a large aneurysmal dilation (aneurysmectomy and vessel ligation) and two for an evacuation of seroma. Conclusion: AVF initial success was good. Late complications such as aneurysms and steal syndrome were almost within the reported rates whilst thrombosis was high.

In the rural areas where most of the world＇s hungry people live, women produce most of the locally consumed food. Their contribution could be much greater if they had equal access to essential resources and services, such as land, credit, and training. In Sudan, women have always been active in agriculture and food security, constituting 17% to agricultural labor force. However, culture coupled with imperfections of official data underestimates their contribution. Accordingly, this study was carried out in the western part of Sudan, namely, North Kordofan State in order to identify and assess the role of women in agriculture and food security and identify the main factors and constraints affecting their contribution to agricultural production in the state. The findings confirm that women contribute 74% to the monthly agricultural income, 65% to total income, 62% to the labor work, and 65% to the household activities. Their average daily working hours are 14, while, those of men are only 8. The study suggests that the removal of the obstacles those women face could increase their contribution to and enhances the livelihood of the people in the state. Hence, a review to the relevant government policies is needed, so that women are empowered by improving their access to resources and credit.

With time concrete / reinforced concrete has become the popular material for construction. Modern industry utilizes this material a lot and has produced various beautiful, eye catching and amazing structures. Due to modern requirements for living and developed construction industries, the old buildings (usually constructed with brick masonry) are demolished and are replaced with new modern buildings. Demolition of buildings results in waste materials which can create waste related problems and environmental issues. By using recycled aggregates weight of concrete can also be reduced, which can also solve problems related to self-weight of concrete. In this paper attempt has been made to use local used bricks from vicinity of Nawabshah, Pakistan, as coarse aggregate. Concrete cubes made with local recycled bricks are cast and tested for overall weight of concrete, moisture content, dynamic modulus of elasticity and compressive strength (nondestructive and destructive methods). The results showed that concrete derived from recycled aggregates attained lower strength than regular concrete. More detailed elaborated work is recommended with different mix ratios and different proportions recycled aggregates for better conclusions.

A single, open and non-comparative study was conducted at Anwar Shah’s First C.P. & Paralysis Clinic and Research Center to evaluate the effects of Aculaser (acupoint-laser) Therapy for children suffering from cerebral palsy (CP) of various types. These children were further classified according to their major complaints. Analysis of the data indicated that 11 children with severe spasticity and stiffness all showed marked improvement (100% success rate); of the 8 children with epileptic fits, 6 patients had a significant reduction in the intensity, frequency and duration of epileptic fits, while the rest 2 cases showed no any improvement or aggravation (75% success rate); out of 5 children with cortical blindness, 2 cases showed complete recovery of vision and 3 had marked improvement (40% cure rate); out of 4 children with hearing difficulties, 2 showed marked improvement (50% success rate); out of 14 children with aphasis, 8 showed improvement (57% improvement rate). Results of this study show that Aculaser Therapy has a high improvement rate of CP children, not only improving the spasticity and stiffness but also the cortical blindness, epilepsy, deafness and speech.

Background: Ischemic stroke is frequently encountered in patients with malignant disease. The pathophysiology of stroke in such cases differs from other subjects with no malignant disease. This study was conducted to compare serum levels of ferritin and d-dimer in cases with ischemic stroke in cancer versus non-cancer patients. Patients and methods: The data of consecutive 264 patients presented with ischemic stroke, confirmed by clinical examination and radiological investigations, were retrospectively reviewed. The included cases were divided into two groups: Group A (non-cancer with stroke, 210 cases) and Group B (cancer with stroke, 54 cases). The collected data included patient demographics, systemic comorbidities, disease and tumor characteristics, in addition to platelet count, serum ferritin and d-dimer. Results: Age, gender, and systemic comorbidities were statistically comparable between the two groups. Additionally, the etiology of stroke and its disability were not statistically different between the two groups. However, the incidence of mortality significantly increased in Group B (25.93% vs. 7.14% of Group A, p = 0.005). Both serum ferritin and d-dimer showed a significant increase in association with cancer (Group B). The former had mean values of 294.54 and 867.87 ng/ml, while the latter had mean values of 463.83 and 888.13 ng/ml in the same two groups, respectively. Conclusion: Serum ferritin and d

In this paper, we propose novel hardware architecture for intra 16 × 16 module for the macroblock engine of a new video coding standard H.264. To reduce the cycle of intra prediction 16 × 16, transform/quantization, and inverse quantization/inverse transform of H.264, an advanced method for different operation is proposed. This architecture can process one macroblock in 208 cycles for all cases of macroblock type by processing 4 × 4 Hadamard transform and quantization during 16 × 16 prediction. This module was designed using VHDL Hardware Description Language (HDL) and works with a 160 MHz frequency using alTERA NIOS-II development board with Stratix II EP2S60F1020C3 FPGA. The system also includes software running on an NIOS-II processor in order to implementing the pre-processing and the post-processing functions. Finally, the execution time of our HW solution is decreased by 26% when compared with the previous work.

关于网络购物(电子商务)对巴基斯坦消费者购买行为影响的研究,直接显示了个体和群体在网络购物中的不同行为。电子商务是为了满足个人、团体和组织的需要,并为他们提供高质量的产品。通过电子商务,消费者可以很容易地购买产品,以及发送给他们的朋友和家人。因为我的研究课题是网上购物(电子商务)对巴基斯坦消费者购买行为的影响。所以我将深入研究电子商务,以及消费者在网上购物方面的行为,例如:为什么在巴基斯坦大多数人都避免购买网上购物,为什么他们更喜欢去直接的实体店购买产品。因此,在我的国家,消费者的网上购物可以选择像达拉茨.pk,Pak ***,每日购物.pk和很多其他的网上购物商店。然而,事实是在我的国家,网上购物工作不像如中国,美国,德国,韩国等发达国家。此外,在我的论文工作中,我会收集更多关于这些因素的信息。有很多与动机有关的理论,这些理论与消费者的视角有关。比如心理需求,安全需求,社会需求,自我实现以及自尊。所以这些需求与消费者是相互关联的,他们的需求会得到满足,然后再转向第二个需求。在调查中,我发现了很多问题,这就是消费者在网上购物时所面临的问题。然而,在我的研究过程中,我收集了一些在广告的比例和频率上都很高的主要问题,比如网购信任度低,付款安全,退款政策,保修索赔,运费高,发货慢等我在问中提到的问题。该方法通过在线调查收集信息。在研究过程中,我制作了问卷表格,发给了我在卡拉奇和海德拉巴两个大城市的朋友和亲戚。问卷调查通过Facebook、Linked In以及电子邮件等渠道发放。此外,我还提供与上述研究相关的数字和表格以便进一步了解。另外,通过研究我收集了有关消费者网上购物相关的信息。这是一个很好的经验,因为我可以更了解在我的国家的网上购物系统,但同时也存在一个负面的情况,在我的国家有61%的消费者不做网上购物。不过,通过对这一现状的了解,使我认识到可以用不同的方法来解决这个问题,这些建议方法将在我的研究中重点阐述。

Genome editing is considered as the most widely used approach of the present era. It had become a basic need of the current micro and molecular biological experiments. Gene engineering finds its widespread applications in medical, industry and agricultural sector. Unlike previous genetic engineering practices to insert or delete a part of genetic material at random place, genome editing allows the precise manipulation of DNA at a specific location. Zinc Finger Nucleases (ZFNs), Transcription Activator like Effector Nucleases (TalENs), Clustered Regularly Interspresed Short Palindromic repeats (CRISPR/Cas system) and meganucleases (recombinases) are the prime tools for editing an organism’s genome. Genome editing tools have an advantage to selectively delete or to integrate specific genes at specific loci. Use of recombinases for specifying site has further reduced time to integrate genes site specifically. Site specific gene stacking by the use of recombinases coupled with ZFNs, TalENs, or CRISPR/Cas genes have paved new pathways to target genes site specifically and to improve germplasm in lesser time than conventional breeding approaches.
