A Dynamic Analysis of the Relationship among Human Development, Exports and Economic Growth in Pakistan.

This study investigates the econometrically empirical evidence of both the short-run and long-run interrelationships among human development, exports and economic growth in an ARDL framework for Pakistan. This study also examines causal linkages among the said variables by applying the Augmented Granger Causality test of Toda-Yamamoto (1995). By using data on Pakistan’s real GDP, real exports and Human Development Index (HDI) for the period 1970-71 to 2008-09, three models have been estimated. The results show cointegration between economic growth, physical capital, real exports and human development when human development is taken as dependent variables. Furthermore, unidirectional Granger causality running from real GDP to real exports has been found in Bivariate, Trivariate and Tetravariate causality framework. The inclusion of HDI as a measure of human development reduces the physical capital share in real GDP whereas it improves the robustness of the regression model. Real GDP seems to provide resources to improve human development in only the long-run while human capital accumulation does not seem to accelerate real GDP both in the short-run and the long-run. The empirical results of the study do not support ‘export-led growth hypothesis’ and human capital-based endogenous growth theory in case of Pakistan, however, it does support ‘growth-driven exports hypothesis’ in case of Pakistan.

A Miniaturized FSS-Based Eight-Element MIMO Antenna Array for Off/On-Body WBAN Telemetry Applications

In this paper, a compact multiple-input multiple-output (MIMO) antenna for an off/on-body wireless body area network (WBAN) is presented. The proposed antenna comprises eight elements arranged in a side-by-side, orthogonal, and across configuration on a planar laminate. This MIMO system achieves wideband impedance matching, i.e., fractional bandwidth (FBW) = 111% (7600 MHz) when placed off-body and FBW = 110% (7500 MHz) when placed on-body. The achieved bandwidth covers the ultrawideband (UWB) ranges 3.1–10.6 GHz for UWB-WBANs. To isolate the antenna elements, a Jerusalem cross (JC)-shaped frequency-selective surface (FSS) and meandered structure (MS) was designed and optimized. This proposed isolation mechanism offers at least 20 dB of isolation while maintaining an overall compact profile. Moreover, MIMO performance parameters for off/on-body and the specific absorption rate (SAR) were also evaluated. Stable MIMO performance, acceptable limits of SAR, and optimum radiation characteristics verify its suitability for wideband biotelemetry applications

Carvedilol vs. esophageal variceal band ligation in the primary prophylaxis of variceal hemorrhage: a multicentre randomized controlled trial.

Background & Aims: Esophageal variceal bleed is a major problem in patients with cirrhosis. Endoscopic variceal ligation (EVL) has been shown to be equal to or better than propranolol in preventing first bleed. Carvedilol is a non-selective b blocker with alpha-1 adrenergic blocker activity. Hemodynamic studies have shown carvedilol to be more effective than propranolol at reducing portal pressure. We compared efficacy of carvedilol with EVL for primary prophylaxis of esophageal variceal bleed. Methods: Cirrhotic patients with esophageal varices were randomized to carvedilol 12.5 mg daily or EVL at three university hospitals of Pakistan. End points were esophageal variceal bleeding, death or liver transplant. Results: Two hundred and nine patients were evaluated. Eighty two and eighty six patients were randomized in carvedilol and EVL arms respectively. Mean age was 48 ± 12.2 years; 122 (72.7%) were males; 89.9% had viral cirrhosis; mean Child-Pugh score was 7.3 ± 1.6 and mean follow up was 13.3 ± 12.1 months (range 1–50 months). Both EVL and carvedilol groups had comparable variceal bleeding rates (8.5% vs. 6.9%), bleed related mortality (4.6% vs. 4.9%) and overall mortality (12.8% vs. 19.5%) respectively. Adverse events in carvedilol group were hypotension (n = 2), requiring cessation of therapy, while transient nausea (n = 18) and dyspnea (n = 30) resolved spontaneously. In the EVL arm, post banding ulcer bleed (n = 1) and chest pain (n = 17), were termed as serious adverse events while transient dysphagia (n = 58) resolved without treatment

Hepatitis C virus genotypes in Pakistan: a systemic review

<p>Abstract</p> <p>Background and aim</p> <p>Phylogenetic analysis has led to the classification of hepatitis C virus (HCV) into 1-6 major genotypes. HCV genotypes have different biological properties, clinical outcome and response to antiviral treatment and provide important clues for studying the epidemiology, transmission and pathogenesis. This article deepens the current molecular information about the geographical distribution of HCV genotypes and subgenotypes in population of four provinces of Pakistan. 34 published papers (1996-2011) related to prevalence of HCV genotypes/serotypes and subgenotypes in Pakistan were searched.</p> <p>Result</p> <p>HCV genotype/s distribution from all 34 studies was observed in 28,400 HCV infected individuals in the following pattern: 1,999 (7.03%) cases of genotype 1; 1,085 (3.81%) cases of genotype 2; 22,429 (78.96%) cases of genotype 3; 453 (1.59%) cases of genotype 4; 29 (0.10%) cases of genotype 5; 37 (0.13%) cases of genotype 6; 1,429 (5.03%) cases of mixed genotypes, and 939 (3.30%) cases of untypeable genotypes. Overall, genotype 3a was the predominant genotype with a rate of 55.10%, followed by genotype 1a, 3b and mixed genotype with a rate of 10.25%, 8.20%, and 5.08%, respectively; and genotypes 4, 5 and 6 were rare. Genotype 3 occurred predominately in all the provinces of Pakistan. Second more frequently genotype was genotype 1 in Punjab province and untypeable genotypes in Sindh, Khyber Pakhtunkhwa and Balochistan provinces.</p
