Abstract: Most of grasshoppers in the family Oedipodidae are the famous agriculture pests in China. However monophyly and the relationships among the subfamilies within this family are unclear up to now. Here the phylogeny of the Oedipodidae was reconstructed based on 16S rDNA sequence fragments by using Mekongiella kingdoni and Atractomorpha sinensis as outgroups under weighted MP, NJ and Bayesian criteria. The 408 bp fragments of mitochondrial 16S rRNA gene were sequenced for 15 species from 4 subfamilies of the family Oedipodidae, and the homologous sequences of other 15 species of grasshoppers were downloaded from the GenBank data library. The numbers of transitions and transversions among pairwise comparisons of the 16S fragments were respectively plotted against percentage sequence differences. Saturation of transitions was discovered, and transversions were not saturated with the increase of percentage sequence difference in the plots. All the individuals of the Oedipodidae excluding Trilophidia annulata were gathered together in the three trees. Our results are very different from the traditionary taxonomy of the Oedipodidae including 4 subfamilies. The Bryodemellinae is not supported as a subfamily, and neither Locustinae nor Oedipodinae are supported as a monophyletic group in this study.

Abstract: Inter professional education (IPE) is the core concept of healthcare department in most of the developed countries on both student and professional level. There is no objection on its necessity. Top ranking universities of the world, especially of developed countries are working on IPE. But some of developing countries like Pakistan are almost unaware of this concept. No one is having the basic concept of IPE, except few, and they are not practicing in IPE so far. Talking about Punjab, there is no awareness for the concept of IPE. It is the need of our healthcare department that we must introduce IPE to improve healthcare quality. This survey was conducted to check the readiness for IPE among pharm D and MBBS students in different institutes of medicine and pharmacy of Lahore. Team went to different pharmacy and medical colleges and asked the students to fill in a questionnaire having 19 items, which was rated by the students on Likert scale. The result shows a conflict in the opinion of pharmacy and medical students. Team also interviewed the respondents shortly. This interview showed many reasons explained by medical students for their response but the most prominent one was the superiority complex. The need of the hour is to introduce IPE in universities for changing the attitude of medical students towards IPE.. Keywords: Interprofessional Education, Interprofessional Learning, Medical Sector, teamwork and collaboration, professional identity, role and responsibilities. |

Abstract: We aimed to recycle the agroindustrial waste resources- pressmud(PM), sugarcane trash (ST) and biomethanated distillery effluent(BE) and produced agronomic valid vermicompost using earthworm, Perionyx excavatus for maintaining natural soil organic and sustainable agricultural activity. Therefore, a series of studies were carried out to convert PM-ST-BE in different proportion vermibeds (T1-1000g PM+0g ST+790ml BE), (T2- 900g PM+100g ST+740ml BE), (T3-800g PM+200g ST+696ml BE), (T4-700g PM +300g ST+655ml BE), (T5-600g PM+400g ST+625ml BE) and (T6-500g PM+500g ST+542ml BE) into vermicompost. The study was to examine the activity of earthworm- growth, reproduction, vermicompost recovery and its nutrient status. The pronounced and better worm activity was found in all vermibeds, especially more in T1 and T3 vermibeds followed by others. This seems to be due to rich cellulose, OC, N, P, microbial activity, enhanced water holding capacity and palatability of the substrates. Enhanced microbial activity, humic acid content, NPK, normalized pH, declined OC, C-N, and C-P ratio, lignin, cellulose, hemicellulose and phenol in vermicompost than normal compost and control. The increased microbial-enzymatic activities contribute an increase in nutrients through nitrification, phosphate solubilization and mineralization. Reduction of OC, C-N, C-P ratio, lignin, cellulose, hemicellulose and phenol in the vermicompost are due to combined action of gut microflaura and earthworm during the vermicomposting process and utilization of these contents by the worm for their growth and reproduction. Finally, our study recommended for the production and application of vermifertilizer from lignocellulosic wastes using vermitechnology for sustainable activity. Keywords: Agroindustrial wastes, pressmud, sugarcane waste, biomethanated distillery effluent, vermicompost. |

Abstract: The use of mass spectrometry imaging (MSI) revealed the localization of a-solanine and a-chaconine as natural toxins for Potato (Solanum tuberosum L.). The content of Potato glycoalkaloids, a-solanine and a-chaconine, were quantitatively determined by high performance liquid chromatography (HPLC). Matrix assisted laser desorption/ionization-based tandem mass spectrometry (MS) could determine a-solanine and a-chaconine from raw potato extraction and section. After budbreak, a-solanine and a-chaconine were produced and localized at periderm and germ compared with that before budbreak. At germ region, these glycoalkaloids did not exist whole germ region but eccentrically localize at germ surface and central region. The amount of a-chaconine was twofold higher than a-solanine at periderm. At germ region, there was no difference between these toxins.

Abstract: Bacteria have a great capacity for adjusting their metabolism in response to environmental changes by linking extracellular stimuli to the regulation of genes by transcription factors. By working in a co-operative manner, transcription factors provide a rapid response to external threats, allowing the bacteria to survive. This review will focus on transcription factors MarA, SoxS and Rob in Escherichia coli, three members of the AraC family of proteins. These homologous proteins exemplify the ability to respond to multiple threats such as oxidative stress, drugs and toxic compounds, acidic pH, and host antimicrobial peptides. MarA, SoxS and Rob recognize similar DNA sequences in the promoter region of more than 40 regulatory target genes. As their regulons overlap, a finely tuned adaptive response allows E. coli to survive in the presence of different assaults in a co-ordinated manner. These regulators are well conserved amongst Enterobacteriaceae and due to their broad involvement in bacterial adaptation in the host, have recently been explored as targets to develop new anti-virulence agents. The regulators are also being examined for their roles in novel technologies such as biofuel production.
