A hallmark trait of chickpea ( cicer arietinum L.) is its ability to form root nodules and to fix atmospheric nitrogen in symbiosis with compatible rhizobia. Chickpea plays a vital role in natural ecosystems, agriculture, and agro- forestry, where its ability to fix nitrogen in symbiosis makes it an excellent settler of low-N 2 environments, and economic and environmentally friendly crop. Forty seven chickpea genotypes were procured from Nuclear Institute for Food and Agriculture (NIFA), Peshawar, Gram Research Station (GRS), Karak, Pakistan and International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India. Entire experiments of the reported project were carried out from 2006 to 2009 at Agricultural University, and NIFA, Peshawar except molecular characterization, which was accomplished at Ehime University Matsuyama, Japan. All genotypes were characterized for marker traits, quantitative parameters, nodulation and molecular markers (SSR). Highly nodulated and non-nodulated parents were picked and hybridized to study mode of inheritance of nodulation and its linkage with marker trait loci. The germplasm was also grouped as desi (pink flower, green with purplish tings stem and colored seed coat) and kabuli (white flower, green stem and white seed coat) types. Highly significant differences and high heritability estimates were recorded for days to 50% flowering, days to maturity, leaf area, number of leaflets leaf -1 , plant height, 100 seed weight, biological yield plant -1 and grain yield plant -1 in all the genotypes. Genotypes from NIFA and GRS were nodulated while genotypes from ICRISAT were Nod - . All genotypes also differed highly and significantly for number of nodules plant -1 . The genotypes NDC 5-S10 and NDC 4-20-4 xproduced the maximum nodules plant -1 . Highly significant response of rhizobium inoculation was recorded for nodules plant -1 and seed yield plant -1 . Interaction of genotypes with treatments classified NDC 4-20-1(16.66) as highly Nod+ and Karak 3 (33 g) as high seed yielder plant -1 . The maximum genotypic mean for nodulation and seed yield plant -1 was recorded for accession NDC 5-S10 (14.83) and Karak 3 (30.20) respectively. Inoculated genotypes exceeded control in treatment means both for nodules plant -1 (10.33 & 7.22) and seed yield plant -1 (14.40 g & 10.59 g). Molecular characterization of 47 genotypes was performed using 10 simple sequence repeat (SSR) markers. Eight of the 10 SSR markers were polymorphic. Number of alleles ranged from 2 to 16, with an average of 7.4 locus -1 . Polymorphic information content (PIC) values ranged from 0.227 to 0.876, with an average of 0.636. The average PIC was 0.582 in desi and 0.577 in kabuli genotypes, shows that both groups are distinct. Significant genetic differentiation was found between desi and kabuli genotypes by using Analysis of molecular variance (AMOVA) under stepwise mutation assumption (R ST = 0.239, P ≤ 0.001). Unweighted pair-group method using arithmetic averages (UPGMA) and Minimum-evolution method (ME) trees as well as Principal Coordinate analysis (PCoA) classified the accessions into 6 groups and all the 6 accessions could be clearly separated. Grouping was mostly the same in both the phylogenetic trees and PCoA, but the branching order differed greatly. Inheritance of nodulation was studied in two cross combinations i.e., ICC 19181(non-nodulated and dark green leaves) x NDC 5-S10 (nodulated and light green leaves) - Hybrid A and ICC 19181 x NDC 4-20-4 (Nod+ and light green leaves) - Hybrid B. Hybrid A, showed monogenic dominant inheritance, while hybrid B showed duplicate gene action for nodulation confirming that both Nod + genotypes are from different clusters. Both hybrids revealed monogenic dominant inheritance of light green leaf color. Linkage study revealed that loci for nod and leaf color resides on the same chromosome at the distance of 15 centi Morgan (cM) in genotype NDC 5-S10 while in genotype NDC 4-20-4 the two loci for nodulation exists at the distance of 26 cM and 15 cM from the locus of leaf color. The current research findings show significant diversity both at morphological and molecular levels, and valuable results regarding rhizobial inoculation, inheritance and linkage study of nodulation, which could play a vital role in future chickpea breeding programs.

غلام رسول سعیدی ؒ کے ترجمہ قرآن کا چھ مختلف تراجم سے تقابل (ایک تحقیقی و تنقیدی جائزہ)

The Quran is the last book of Allah. The Quran was revealed in Arabic. The Qur'an was not revealed only to the Arabs. This book has been published to guide all Human beings. There for, translation of the Quran is necessary for non-Arabs. The translation of the Quran was started in the beginning of Urdu language. So far there have been many translations of the Holy Quran in Urdu . I have compared Allama Saeedi's translation of the Qur'an with other translations in this article. I have proved in this article that their translation is an extension of the Quran, the Barelvi school. Their translation is often matched by professional translation in many places. Barelvi School has original (genin), translation, Quran, Maulana Ahmad Raza Khan Barelvi and Allama Syed Mohammad Kachochvi. This work of mine is unique in its investigation  of Allama Ghulam Rasool Saeedi. In my opinion, resding the Qur’an is essential for the understanding of the Qur’an in order to understand the Qur’an but also the study of translations that have a distinct identity and they have been the study of our teachers.

Study of Selected Nutraceuticals on Management of Type-2 Diabetes

Background: Diabetes mellitus has spread as a pandemic on the globe, over the last few decades, with no geographical, cultural and economic bounds. Life style has emerged as the causative factor and its modification coupled with dietary intervention are the mainstay in its management. Recently the use of nutraceuticals has become popular alternative for the chronic diseases particularly diabetes. Methods: The present study was conducted to evaluate the effect of some selected nutraceuticals in relation to placebo on management of Diabetes Mellitus Type-2. These included Cinnamon (Cinnamomum cassia), Fenugreek (Trigonella foenum-graecum), and Chromium Picolinate. The proximate analysis of Cinnamon & Fenugreek was also done to assess the amount of macronutrients, moisture, ash and fiber content. It was a Randomly Controlled Trial. A sample size of 104 subjects was selected which was equally divided in four intervention groups of 26 each (Cinnamon, Fenugreek, Chromium and Placebo). Biochemical parameters such as Diabetic profile (FPG, Insulin levels, HbA1c), Lipid profile (Cholesterol, Triglycerides, HDL , LDL and VLDL), Hepatic (ALT, ALP), Urinary/Renal profile (microalbumin, total urinary Protein & creatinine) and Blood Complete Picture was studied at three stages i.e. at baseline, three month after intervention and at end of one month washout period. The anthropometric, clinical and dietary data was also collected. The data was analyzed on SPSS 22. Apart from descriptive statistics, data was subjected to repeated measure analysis, and MANOVA to compare all the phases of intervention and inter comparative analysis of three nutraceuticals with placebo. Results: The result outcome was divided and discussed under A, B, C, and D of nutritional status assessment. i.e., Anthropometric, Biochemical, Clinical and Dietary profile of the patients respectively. Out of 104 subjects, 55.8% were males and 44.2% were females. 78% of the subjects were educated having different levels of education; while 22% had no formal education. Majority (63.5%) of the subjects were having sedentary life style. 97% of the subjects shared that they were suffering from some level of stress. Smoking was not common as 64% of the male subjects never smoked, while 87 % of the female population was non- smoker. 74% of the subjects had family history of diabetes, among these 57.70% had close diabetic near relative in the family. vii Majority (89.4%) of the subjects had BMI above normal. None was under weight and only 10.6% were in normal range. Obesity was more prevalent in females as compared to males in all three phases of the study. Intervention of the selected nutraceuticals and change in life style positively affected the mean values of BMI. Central obesity was common feature as 55.8% of the total population was suffering from it. The effect of interventions on anthropometrics was generally positive which was not specifically related to any one of the nutraceuticals as compared to placebo. The statistical analysis proved cinnamon was better in managing different aspects of T2DM with P value of <0.05 as compared to other two nutraceuticals. The descriptive analysis also depicted that the mean marginal difference of cinnamon had better effect on fasting sugar, insulin levels and HbA1c followed by chromium and fenugreek. All the nutraceuticals had some effect on lipid profile (Cholesterol, triglycerides, HDL and LDL) with minor drop towards lower range as compared to placebo. It remained within normal range in all three phases of the study. The Huynh Feldt test was used to measure the significance of “Test of Within Subject Effects” in which the p- value of less than 0.05 which is significant and shows the considerable impact on the dependent variable i.e. diabetic profile. The clinical signs and symptoms and dietary patterns also improved by the end of intervention phase, the impact of which lasted even during the washout period. The estimated marginal means depicted that cinnamon was more prominent in its role followed by chromium and fenugreek with least effect of placebo. The multivariate analysis shows a highly significant difference between ALT levels of all phases (p=0.000). The comparison of different of interventions showed not much difference between them as the p-value was more than 0.050. This shows that although all interventions had some effect on maintaining the ALT and ALP levels of blood towards normal. It was safe to use as no liver toxicity was observed due to intake of any of the nutraceutical for three months.
