Asim Mushtaq, Mujahid Azeem Tariq, Umer Rashid, Amber Afroz, Nadia Zeeshan, Abdul R. Asif, Muzna Zahur
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.49115
Abstract:

Hepatitis C has a 3% of the global disease burden that remains endemic in many regions of the world. According to a general statistical survey it has approximately 5.3% seroprevalence in Pakistan. HCV is a persistent and silent disease thus making the primary diagnosis complicated. Occasionally HCV positive population could not be diagnosed by routine HCV antibody testing therefore requires molecular diagnosis. This study is aimed to determine the prevalence of HCV and to estimate the HCV viral load by quantitative analysis among different patient groups of District Gujrat, Pakistan. A total of 597 samples were collected from clinically diagnosed liver patients that were categorized into three age groups: 1) up to 25 years; 2) 26-50 years 3) above 50 years. All samples were subjected to real time PCR for determination and quantification of HCV RNA. Activity of liver aminotransferases was measured. The overall prevalence of HCV-RNA was 73.87%. Females had slightly higher HCV prevalence which is 74.06% while 73.45% in males. Highest prevalence of active HCV infection was found in age group 26-50. In addition, liver function tests showed that 28.12% HCV-positive patients do not have elevated ALT level whereas 32.65% did not show elevated AST levels. It may be assumed that there is not a significant relationship between increased viral load and liver amino transferases. The study concluded a significantly higher rate of HCV infection in young population. Moreover screening with antibody and liver function tests alone does not exclude the possibility of HCV infection.

Homeobox leucine zipper proteins and cotton improvement  [PDF]
Muzna Zahur, Muhammad Ahsan Asif, Nadia Zeeshan, Sajid Mehmood, Muhammad Faheem Malik, Abdul R. Asif
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.410A3003
Abstract:

Transcription factors play key roles in plant development and stress responses through their interaction with cis-elements and/or other transcription factors. Homeodomain associated leucine zipper proteins (HD-Zip) constitute a family of transcription factors that are characterized by the presence of a DNA-binding domain closely linked with leucine zipper motif functioning in dimer formation. This type of association is unique to plants and considered as an excellent candidate to activate developmental responses to altering environmental conditions. Cotton is the most important fiber plant with a lot of local and commercial uses in the world. HD-Zip proteins not only have key roles in different stages of vascular and inter-fascicular fiber differentiation of cotton but also are suggested to have an important role against abiotic stress that is one of the key factors limiting cotton productivity. Plants have developed various strategies to manage stress conditions through a combination of metabolic, physiological and morphological adaptations. These adaptive changes rely largely on alterations in gene expression. Therefore, transcriptional regulators play a crucial role in stress tolerance. Being a transcription factor HD-Zip might be a useful target for genetic engineering to generate multiple stress tolerance in susceptible plants. In the following chapter, we discussed how the HD-Zip proteins would play a useful role for cotton development both in fiber production and stress adaptation.

Advances in lignocellulosic biotechnology: A brief review on lignocellulosic biomass and cellulases  [PDF]
Tanzila Shahzadi, Sajid Mehmood, Muhammad Irshad, Zahid Anwar, Amber Afroz, Nadia Zeeshan, Umer Rashid, Kalsoom Sughra
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.53031
Abstract:

From the last few decades, there has been an increasing research interest in the value of lignocellulosic biomass. Lignoellulosic biomass is an inexpensive, renewable abundant and provides a unique natural resource for large-scale and cost-effective bio-energy collection. In addition, using lignocellulosic materials and other low-cost biomass can significantly reduce the cost of materials used for ethanol production. Therefore, in this background, the rapidly evolving tools of biotechnology can lower the conversion costs and also enhance a yield of target products. In this context, a biological processing presents a promising approach to converting lignocellulosic materials into energy-fuels. The present summarized review work begins with an overview on the physio-chemical features and composition of major agricultural biomass. The information is also given on the processing of agricultural biomass to produce industrially important enzymes, e.g., ligninases or cellulases. Cellulases provide a key opportunity for achieving tremendous benefits of biomass utilization.

Open Journal of Epidemiology (OJEpi) , 2015, DOI: 10.4236/ojepi.2015.51002
Abstract: Dengue virus infection is more and more acknowledged as one of the world’s major escalating problems. Dengue is prevalent in most tropical and subtropical countries. To solve this problem, pharmacists need to understand the epidemiology, risk factors, clinical spectrum, diagnosis, management, prevention, and novel avenues of dengue.
Management of Hinchey II diverticulitis
Soni Soumian, Sudeep Thomas, Prasoon P Mohan, Nadia Khan, Zeeshan Khan, Tirumala Raju
World Journal of Gastroenterology , 2008,
Abstract: Colonic diverticulosis can either be asymptomatic or present with complications resulting in significant morbidity and mortality. A key presentation of complicated disease is abscess formation (Hinchey type II). The natural course of this is unclear and therefore treatments range from conservative approach with antibiotics and percutaneous guided drainage (PCD) to surgery. There is no clear consensus on the exact management strategy. A Medline based literature search specifically looking at studies dealing with Hinchey type II diverticulitis and its management was carried out. For comparison, five-year retrospective data of diverticular abscesses from our institution was collected and the outcome analysed. Various studies have looked into this aspect of the disease, elaborating on the significance of the size and location of the abscesses, the role of PCD, recurrence rates and the controversies regarding the need for elective surgery. Conservative treatment with antibiotics alone is effective in a majority of cases with a role for PCD in large safely accessible abscesses. Variable recurrence rates have been reported in literature and elective surgery should be planned for selected groups of patients.

Journal of Building Construction and Planning Research (JBCPR) , 2018, DOI: 10.4236/jbcpr.2018.64016
Abstract: Change orders are common and clearly noticeable in Jordanian construction industry. Several studies have identified change orders as significant problem in Jordanian construction projects, and they mainly cause delay and cost overrun. This situation spurs the researchers for investigating the significant causes of change orders in construction projects. Thus, this paper aims to determine the main causes of change orders in the Jordanian construction private sector which responsible for significant cost overrun. Both qualitative and quantitative methods, i.e. interview and questionnaire techniques, were used to achieve this aim. Interviews were conducted as the first stage of data collection, and the results formed the basis of the questionnaire, which was distributed across the Jordanian construction sector. Content analysis was used to analyse the interview responses, while factor analysis, correlation and the Severity Index (SI) were used to analyse the questionnaire results. The findings identified three main categories of causes of change orders in private sector, namely engineering causes, causes related to the client, and circumstances of the project, with sub-causes in each category which are related to each other in significant ways and which affect each other.

Abstract: Topical application of glyceryl trinitrate (GTN) ointment heals anal fissures, providing an alternative to the traditional first linetreatment of surgical sphincterotomy. Setting: Tathlith General Hospital Saudi Arabia. Period: January 2001 – April 2003. Objective: Todetermine the effectiveness and safety of topical 0.5% glyceryl trinitrate (GTN) in the management of chronic anal fissure. Patients & methods:Individual Patients were randomized to receive 0.5%GTN paste or placebo three times per day for six weeks in addition to oral senna and/orlactulose. Patients took laxatives alone for further 6 weeks. Patients were followed every week for six weeks and then fortnightly for anothersix weeks to assess pain scores and were given advice. Results: Fifty patients were recruited in this study and 44 patients completed the trial (23 in the GTN group and 21 in the placebo group), patients who could not complete the study were excluded. At 6 weeks, 74% of patients had no pain in the GTN group as compared to the 29% in the placebo group. In 26% of cases treatment was unsuccessful. At three month follow up there was no early recurrence. The prevalence of headaches was 65% in GTN group ( reported by 15 patients) and 24% in placebo group (reported by 5 patients). Mean pain scores were lower in the GTN group as compared to the placebo group. Conclusions: The use of 0.5% GTN induces healing of chronic anal fissures and may by used as a first line of treatment in patients with chronic anal fissure. Successful treatment may come at the expense of a high incidence of headaches.
