ABSTRACT
Objective: The research paper aims at the comparison of Nifedipine and Hydralazine safety and efficacy in the hypertension management during pregnancy. Study Design: The in-hand research design is RCT (Randomized Control Trial). Place and Duration: The venue of the in-hand research paper was Mother and Child Health Unit-II which is located in Pakistan Institute of Medical Sciences, Islamabad. The research commenced from 1st January, 2017 and concluded on 1st July, 2017. Methodology: The number of patients included in research paper was. These patients were diagnosed hypertension and their age was beyond twenty-eight weeks of gestation were enrolled as sample of the research paper after informed consent. Total number of patients was divided into two groups namely Nifedipine and Hydralazine groups. Patients were allocated groups randomly either Nifedipine or Hydralazine group. Before the start of treatment on the right side the blood pressure was checked in supine position, the same check was repeated at the interval of half hour continuously till two hours. Patients were also noticed for the presence of any side effect of the drugs. Results: Initial mean Blood Pressure reading was noted as 170/113 mmHg. One-hour time was effective for the control of systolic blood pressure of Nifedipine group; whereas, one and half hour was for the Hydralazine group. Both the groups were observed same time for the diastolic blood pressure that was one hour respectively for both the groups. Mean time of four and a half days was observed for the pregnancy prolongation in Nifedipine group; whereas, the same time for the Hydralazine group was two days. The p-value was significantly calculated as 0.02. Nifedipine group was treated with few doses of medication. Hydralazine group reflected association of palpitation, flushing, persistent Hypertension and tachycardia with the respective proportions of 56%, 56%, 16.7% and greater than 110 bpm (20%). No other significant difference was observed in the scaled variables of feto-maternal results with an exception of headache caused by Nifedipine in seventy-three percent of the cases after drug administration. Conclusion: In the scholastic research it is concluded that during pregnancy hypertension can best be controlled through Nifedipine in comparison with Hydralazine.
ABSTRACT
Present study was aimed to screening the population of 25 wheat genotypes from Baluchistan region of Pakistan along with five commercial cultivars for leaf rust adult plant resistance (APR) through gene postulation using natural inoculation of Puccinia triticina Erikss local pathotype. Infection severity was recorded on scale in comparison with susceptible control "Morroco" cultivar. On the basis of phenotypic score, seven accessions and four varieties (Zardana-89, Sariab-92, Zarlashta-99 and Raskoh-05) with AUDPC values up to 20% were characterized as resistant genotypes. Coefficient of infection (CI) score ranged from 0-10 for some accessions and cultivars showing high level of adult plant resistance. Furthermore, bi-allelic STS marker csLV34 having close linkage with Lr34 (0.4cM). This marker amplified one gene specific allele of 150bp in 21 genotypes, including 19 accessions and two commercial varieties (Sariab-92 and Zarghoon-79) which confirmed presence of Lr34 gene conferring adult plant resistance against leaf rust. The rust pathogenicity scale varied for accessions from resistant to moderately susceptible. However, beside Lr34, phenotypic gene postulation, in combination with marker assisted selection for leaf rust resistance, has revealed presence of some other unknown resistance genes in local wheat germplasm which signified its use in wheat improvement programs both locally and abroad.
O presente estudo teve como objetivo a triagem da população de 25 genótipos de trigo do Baluchistão, região do Paquistão, juntamente com cinco cultivares comerciais para o estudo da resistência à ferrugem da folha em plantas adultas (leaf rust adult plant resistance, APR, em inglês) através da postulação gênica usando a inoculação natural do patótipo local da Puccinia triticina Erikks. A gravidade da infecção foi registrada na escala em comparação ao cultivar de controle suscetível "Morroco". Com base na pontuação fenotípica, sete acessões e quatro variedades (Zardana-89, Sariab-92, Zarlashta-99 and Raskoh-05) com valores de AUDPC (area under the disease progress curve, em inglês) até 20% foram caracterizados como genótipos resistentes. A pontuação do coeficiente de infecção (CI) variou no intervalo de 0-10 para algumas acessões e cultivares evidenciando uma elevada resistência nas plantas adultas. Além disso, o STS marker para o csLV34 bi-alélico demonstrou uma ligação estreita com o Lr34 (0.4cM). Este marcador amplificou um alelo específico do gene do 150bp em 21 genótipos, incluindo 19 acessões e duas variedades comerciais (Sariab-92 and Zarghoon-79) o que confirmou a presença do gene Lr34 conferindo resistência às plantas adultas contra a ferrugem da folha. A escala de patogenicidade da ferrugem para as acessões de resistente a moderadamente suscetível. Contudo, além do Lr34, a postulação gênica fenotípica, em combinação com a seleção auxiliada (ou assistida) por marcadores para a resistência da ferrugem da folha, revelou a presença de outros genes resistentes desconhecidos no germoplasma do trigo local o que justifica a sua utilização em programas de melhoramento do trigo tanto a nível local quanto a nível internacional.

Remarkable progress has been achieved in the percutaneous management of coronary artery disease over the last decade. In the early 1990s, the primary success rate with the use of bare metal stents was 86-88% and the restenosis rate, 30%-40%. Over the last decade, drug-eluting stents have been developed to check the high rates of in-stent restenosis following percutaneous coronary revascularization. In randomized trials, polymer-coated sirolimus- and paclitaxel-eluting stents, when compared to bare metal stents, have been shown to markedly reduce the incidence of both angiographic restenosis and repeat revascularization. The effectiveness of drug-eluting stents in the prevention of restenosis has been confirmed in patients with stable stenotic lesions, as well as many patients with specific lesions, such as those with in-stent restenosis and acute myocardial infarction. Currently, the primary success rate using drugeluting stents has risen to over 95% and the restenosis rate to less than 10%. In spite of remarkable technological advances and improved outcomes with percutaneous coronary revascularization, chronic total occlusions of the coronary artery remain a source of procedural frustration and clinical uncertainty. With continued developments in catheterbased technologies, there is an opportunity to achieve recanalization of chronic total occlusions with drug-eluting stents; this subset of patients is now recognized as the last formidable barrier to the success of percutaneous revascularization. This review provides an overview of the pathophysiology of chronic total occlusions and the clinical outcomes associated with chronic total occlusion revascularization, and provides future directions for clinical investigation.
