Hospitals play a vital role in health and well being of humans. However the biomedical waste generated by hospitals pose a serious threat to public health and environment due to their high potential of disease transmission through spread of pathogenic bacterial strains from hospitals dumpsites by any mode of contact. Therefore methods for the analysis of microbial diversity in the environmental samples surrounding the hospitals? dumpsites are required for better understanding of Hospitals Acquired Infections (HAI) transmission. Metagenomics provides solution to this problem through availability of methods that allows the isolation of those microbial DNA from environment that cannot be cultured and hence their role has never been studied in transmission of HAIs. This research study is objected to the investigation of microbial diversity present in the soil surrounding the dumpsites of hospitals in order to construct a profile of bacterial communities present in natural environment of hospitals that may potentially be involved in transmission of HAIs. In this research study the microbial diversity of soil samples taken from 10 different hospital?s waste dumpsites was examined. Direct DNA extraction is performed by using Metagenomic approach with the objective of isolation of not only cultured but un-cultured bacterial communities as well. PCR was carried out for all samples for detection of 16S rRNA gene. Amplified DNA is directed to 16S rRNA gene sequencing. After sequencing the Phylogenetic analysis is performed through Phylogenetic tree rendering for the analysis of evolutionary relatedness of extracted bacterial sequences among themselves and with their possible closest species. The results of this research study have provided with the profile of bacterial species present in the soils surrounding the hospitals? dumping sites and also their evolutionary relatedness with other bacterial species. The results provided by this study have promising contribution in investigation of microbial communities present in hospitals environments and their potential involvement in transmission of HAIs suggests the need of strategies and protocols for proper disposal of biomedical wastes generated by hospitals.

مو لانا عبدالصمد رحمانی

مولانا عبدالصمد صاحب رحمانی
دوسرا حادثہ مولانا عبدالصمد صاحب رحمانی نائب امیر شریعت صوبہ بہار و اڑیسہ کا ہے وہ بھی پرانی یادگار، اس دور کے نامور عالم اور ملک و ملت کے پرانے خدمت گزار تھے، ملکی و ملی تحریکات میں ان کا نمایاں حصہ رہا، خلافت اور ترک موالات کی تحریک اور ہندوستان کی آزادی کی جدوجہد میں مولانا سجاد بہاری مرحوم کے رفیق کار تھے، ان کی وفات سے ایک قدیم یادگار اٹھ گئی، اﷲ تعالیٰ ان کے مدارج بلند فرمائے۔

Exploring the Role of “Jihad” in the Establishment of Universal Peace

Jihad is an umbrella concept of Islam, but unfortunately, nowadays it is misused both as a terminology and practice in a very narrow sense. The concept of jihad is crystal clear in Islam but it has been made dubious by certain schools of thought for achieving their vested interests. Consequently differences of opinions about the definition of jihad emerged not only among the masses but also in the circles of the learned ones, hence, no agreed upon definition emerge. Due to this, questions are raised like whether jihad is synonymous to terrorism? Or what is the fundamental role of jihad in establishing universal peace? What is the modus operandi of jihad? But so far, no scholarly effort has been made to hammer this issue out in an unbiased and objective manner. Whatever has been done consist more on either argumentative encounter or defending one’s own ideological stance. For that reason this research article attempts to carry out an objective analysis of the role of jihad in the establishment of universal peace. It is hoped that this attempt of intellectual pursuit will not only be a source of guidance to the common people but will also open new avenues for research scholars in this field.

Characteristics of Heavy Metal Uptake and Accumulation in Selected Plant Species for Development of Phytoextraction Technology.

soil, especially agricultural fields contaminated with toxic metals, has become a global problem and demands economic, efficient and environment friendly remediation technologies. Phytoextraction is a potential plant-based technology for the decontamination of polluted soil and water. It is an economic, solar driven, and environment friendly technology. In the present study, physiological, biochemical and molecular characteristics of cadmium uptake and accumulation in three plant species (Parthenium hysterophorus, Ricinus communis and Cannabis sativa) were studied for the development of phytoextraction technology. In the first experiment, different treatments of Gibberellic Acid (GA3 10−2, 10−4 and 10−6 M as foliar spray) and Ethylenediaminetetraacetic acid (EDTA 40 mgKg-1 soil as single dose and 10 mgKg-1 soil given in four doses) were studied for their effects on Cd phytoextraction, and concentration of proline, phenolics and chlorophyll in Parthenium hysterophorus plants grown in Cd (100 ppm) contaminated soil. The plants showed Cd hyperaccumulator potential based on Cd bio-concentration factor (BCF > 1 in control plants). The GA3 and EDTA application increased the extent of Cd phytoextraction by the plants. Most significantly increase in Cd accumulation and bio concentration (BCF 9.75 ± 0.34) were found in plants treated with GA3 (10−2 M) in combination with split doses of EDTA. Gibberellic acid significantly increased the concentrations of phenolics and chlorophyll in the plants. Cadmium accumulation in plant tissues showed positive correlation with free proline (R2 = 0.527, R2= 0.630) and total phenolics (R2 = 0.554, R2 = 0.723) in roots and leaves, respectively. In the second experiment, physiological and biochemical analyses were performed. The objectives were to assess the effect of Molybdenum (Mo 0.5, 1.00 and 2.00 ppm) on Cd phytoextraction, and concentration of endogenous proline, phenolics and photosynthetic in Ricinus communis and Cannabis sativa plants grown in Cd (25, 50 and 100 ppm) contaminated soil. Molybdenum was applied as a foliar spray, soil addition and seed soaking. Foliar spray of Molybdenum highly increased Cd uptake and accumulation in both plants. Molybdenum seed soaking and foliar spray highly increased the biomass, concentration of free proline and total phenolics as compared to control plants. Positive correlations of proline and phenolics with Cd accumulation were found in roots and leaves; suggesting a significant role of proline and phenolics in Cd phytoaccumulation. Molecular investigation was carried out with objectives: (1) To determine the presence and then expression of DREB-1A, DREB-1B, DREB-1F and CBF like genes in Ricinus communis and Cannabis sativa plants, (2) To evaluate the effect of molybdenum and cadmium on expression of these genes, (3) To correlate the expression of genes with Cd accumulation, and free proline and total phenolics concentrations in plants. Molybdenum was applied as a foliar spray (0.5, 1, 2 ppm) while Cd (50 ppm) was added to soil. cDNA was synthesized through reverse transcriptase Polymerase chain reaction (RT-PCR). PCR from genomic DNA and cDNA with genes specific primers were performed. The PCR products were sequenced and compared the nucleotide sequences and deduced amino acid sequences for homology with other plants. Results confirmed the presence of DREB-1A, DREB-1B, DREB-1F and CBF like genes in R. communis. In C. sativa the genes were identified for the first time. Cadmium induced the expression of DREB-1B, DREB-1F and CBF like genes in both the plants while molybdenum foliar spray further increased the expression of these genes under Cd stress. The DREB-1A showed no expression in both the plants while its presence was confirmed by the PCR product of genomic DNA with gene specific primers. The CBF-like gene was expressed in both the plants sprayed with molybdenum (without Cd), while the other genes were not expressed with Mo only. The DREB-1F and CBF like gene of both the plants showed more than 80 % nucleotide sequence homology with these genes in other plants. Predicted amino acid sequence of DREB-1F from both plant showed more than 75% homology with protein sequences of other plants, while the CBF like gene demonstrated more than 80% homology with protein sequences of other plants species. The expression of DREB-1B, DREB-1F and CBF-like genes (semi quantitative) was positively correlated with Cd accumulation, free proline and total phenolics in Cannabis sativa plant, while these correlations were significantly positive in Ricinus communis. Application of GA3 and Mo increased concentration of Cd in plants tissues. A positive inter-correlation was found between Cd concentration in plant tissues, production of prolin and phenolics and the expression of DREB-1B, DREB-1F and CBF-like genes.
