Jurisprudence of a Fledgling Federation: A Critical Analysis of Pakistan’s Judicial View on Federalism

Although the impediments in development of federation in Pakistan can be explored from different facets, this paper aims to critically analyze the constitutional history and judicial interpretation of federalism in Pakistan against the scholarly and conceptual debates over the idea. The paper argues that Pakistan’s judiciary, despite recognizing federalism as cornerstone of the Constitution, has not upheld the principle as strongly as other salient features of the Constitution. The superior judiciary has strengthened the official discourse of a unitary national identity leaving little room for ethnical pluralism and participatory nationalism. The paper shall also review measures introduced by the recent 18th Amendment to the Constitution of Pakistan to promote provincial autonomy and will also make further suggestions to improve the federal scheme of Pakistan

Use of Tranexamic acid is a cost effective method in preventing blood loss during and after total knee replacement

<p>Abstract</p> <p>Background & Purpose</p> <p>Allogenic blood transfusion in elective orthopaedic surgery is best avoided owing to its associated risks. Total knee replacement often requires blood transfusion, more so when bilateral surgery is performed. Many strategies are currently being employed to reduce the amount of peri-operative allogenic transfusions. Anti-fibrinolytic compounds such as aminocaproic acid and tranexamic acid have been used systemically in perioperative settings with promising results. This study aimed to evaluate the effectiveness of tranexamic acid in reducing allogenic blood transfusion in total knee replacement surgery.</p> <p>Methodology</p> <p>This was a retrospective cohort study conducted on patients undergoing total knee replacement during the time period November 2005 to November 2008. Study population was 99 patients, of which 70 underwent unilateral and 29 bilateral knee replacement. Forty-seven patients with 62 (49.5%) knees (group-I) had received tranexamic acid (by surgeon preference) while the remaining fifty-two patients with 66 (51.5%) knees (group-II) had did not received any tranexamic acid either pre- or post-operatively.</p> <p>Results</p> <p>The mean drop in the post-operative haemoglobin concentration in Group-II for unilateral and bilateral cases was 1.79 gm/dl and 2.21 gm/dl, with a mean post-operative drainage of 1828 ml (unilateral) and 2695 ml (bilateral). In comparison, the mean drop in the post-op haemoglobin in Group-I was 1.49 gm/dl (unilateral) and 1.94 gm/dl (bilateral), with a mean drainage of 826 ml (unilateral) and 1288 ml (bilateral) (p-value < 0.001).</p> <p>Interpretation</p> <p>Tranexamic acid is effective in reducing post-operative drainage and requirement of blood transfusion after knee replacement.</p

An overview of the trichostorngyloidea

Among helminthes, the trichostrongyloidea consists of most significant parasites of ruminants, which are posing significant threats to livestock productivity, health and well-being. This brief commentary provides an overview of this important group of parasite to showcase the crucial roles these play in hosts

Understanding of the molecular genetics of benzimidazole resistance in haemonchus

Parasitic infestations are continuously posing enormous threats to food security and poverty alleviation. While different drugs are proposed to minimize the impact of parasite, these come with established genetic resistance. Understanding markers of genetic resistance will streamline the process of use of alternative medication as well as assessing the affect of currently applied anthelmintic. This review briefly outlines the roles of parasites in diseases and proposes the use of different genetic markers to mitigate the emerging resistance in parasite

A loop-mediated isothermal amplification (LAMP) assay to identify isotype 1 β-tubulin locus SNPs in synthetic double-stranded Haemonchus contortus DNA

Development of sustainable gastrointestinal nematode (GIN) control strategies depends on the ability to identify the frequencies of drug-susceptible and resistant genotypes in GIN populations arising from management practices undertaken on individual farms. Resistance to BZ drugs in GINs has been shown to be conferred by the presence of defined SNPs in the isotype 1 β-tubulin locus. Loop-mediated isothermal amplification (LAMP) assays are amenable to use on a range of DNA templates and are potentially adaptable to use in practical, cost-effective, pen-side diagnostic platforms that are needed to detect anthelmintic resistance in the field. In this study, we designed primers and examined LAMP assays to detect each of the three major isotype 1 β-tubulin SNPs conferring genetic susceptibility to BZ drugs. We used artificial pools of synthetic DNA, containing different proportions of susceptible and resistant SNPs to determine reproducibility of the assays. We demonstrated the detection of each of the isotype 1 β-tubulin SNPs conferring susceptibility to BZ drugs using the optimal LAMP assay. Isotype 1 β-tubulin SNP typing was effective in detecting BZ susceptibility, but the accuracy was reduced in samples with less than 60 % susceptible DNA. Our results show the potential for LAMP SNP typing to detect genetic susceptibility or resistance to anthelmintic drugs in livestock GINs, and some of the limitations in our approach that will need to be overcome in order to evaluate this assay using field samples.
