Role of Pakistani Universities in Interfaith Dialogue, Harmony and Relations An Index and Bibliometric of Produced Academic Dissertations
Interfaith dialogue has become one of the most significant and interesting activities in contemporary socio-political and socio-religious global scenario due to its crucial role in the peace process and peaceful interfaith relations. Many groups of scholars, institutes, organizations, and even governments are promoting the activities regarding interfaith relations. Meanwhile, it is also assumed that Pakistan is one of the countries where interfaith dialogue activities are arranged officially on the state level. In this study, efforts are made to review statistically and to index the literature produced by Pakistani scholars and universities. A mixed-method research methodology is adopted for this study with a bibliometric approach to find out results. Almost 136 theses & dissertations have been produced by scholars in a wide range of Pakistani Universities on interfaith Dialogue, religious debates, harmony, and relations. The research produced by male scholars was 71 (52.21 %) and most 49 (36%) productive era was from 2011 to 2015. The majority of the research was for Master (38%) and MS/M.Phil (34%) level degrees and about one-fifth of the theses were on the theme of “Interfaith Dialogue in Pakistani context”. Therefore, it is suggested that the course on interfaith dialogue, harmony, and relations should be taught at M. Phil and Ph.D. Level in the discipline of Islamic studies and social sciences

An Analytical Study of Library & Information Sciences Journals Published in Pakistan
This descriptive study was conducted in Pakistan in February 2021. The main objective was to identify and discuss the various aspects of the research journals of Library & Information Sciences (LIS) published form Pakistan till date. Documentary analysis was made for acquiring the basic and desired information about these journals. The scrutiny of the available record revealed that seven LIS journals are being published in Pakistan. Out of seven, three were Higher Education Commission (HEC) recognized. Two LIS journals are charging publication fee from authors. Five journals were started publishing in last decade by LIS schools or organizations working for LIS professionals in Pakistan. Amazing is to note that none of the Journals has Impact Factor and the oldest journal Pakistan Library Information Science Journal (PLISJ) has been de recognized after journey of 52 years. The LIS community of Pakistan needs to improve the quality of research journals to meet the international standards in the field of Library & Information Studies
MAC Spoofing Detection Via Wireshark
When computers are, connect on any network a network card is used, known as NIC card which is having a MAC address. This address is use to distinguish one system from another we may say that it is the physical address given by the manufacturer to provide a unique identity to equipment. We have studied that MAC address is permanent and cannot be changed but there are different ways in which MAC address of equipments could be changed whether it is a pc/laptop or mobile. We could use wire shark to know the changed MAC address of any system for which the packet is been send or received. The change in MAC is called MAC spoofing, which is having advantages as well as disadvantages
Direct Sensing of Endothelial Oxidants by Vascular Endothelial Growth Factor Receptor-2 and c-Src
BACKGROUND: ADPH oxidase-derived reactive oxygen species (ROS) play important roles in redox homeostasis and signal transduction in endothelial cells (ECs). We previously demonstrated that c-Src plays a key role in VEGF-induced, ROS-dependent selective activation of PI3K-Akt but not PLCÎł-1-ERK1/2 signaling pathways. The aim of the present study was to understand how VEGFR-2-c-Src signaling axis 'senses' NADPH oxidase-derived ROS levels and couples VEGF activation of c-Src to the redox state of ECs. METHODOLOGY/PRINCIPAL FINDINGS: Using biotinylated probe that detects oxidation of cysteine thiol (cys-OH) in intracellular proteins, we demonstrate that VEGF induced oxidative modification in c-Src and VEGFR-2, and that reduction in ROS levels using siRNA against p47(phox) subunit of Rac1-dependent NADPH oxidase inhibited this phenomenon. Co-immunoprecipitation studies using human coronary artery ECs (HCAEC) showed that VEGF-induced ROS-dependent interaction between VEGFR-2 and c-Src correlated with their thiol oxidation status. Immunofluorescence studies using antibodies against internalized VEGFR-2 and c-Src demonstrated that VEGF-induced subcellular co-localization of these tyrosine kinases were also dependent on NADPH oxidsase-derived ROS. CONCLUSION/SIGNIFICANCE: These results demonstrate that VEGF induces cysteine oxidation in VEGFR-2 and c-Src in an NADPH oxidase-derived ROS-dependent manner, suggesting that VEGFR-2 and c-Src can 'sense' redox levels in ECs. The data also suggest that thiol oxidation status of VEGFR-2 and c-Src correlates with their ability to physically interact with each other and c-Src activation. Taken together, these findings suggest that prior to activating downstream c-Src-PI3K-Akt signaling pathway, VEGFR-2-c-Src axis requires an NADPH oxidase-derived ROS threshold in ECs
Corrigendum: The Application of the Extended Poincaré Plot in the Analysis of Physiological Variabilities
Assessment of Food Safety Knowledge, Attitudes and Practices of Food Service Staff in Bangladeshi Hospitals: A Cross-Sectional Study.
Food safety knowledge, attitudes and practices among hospital food service staff are crucial in the prevention of foodborne disease outbreaks, as hospitalized patients are more vulnerable to potential hazards. This study, therefore, sought to assess the food safety knowledge, attitudes and practices of food service staff in Bangladeshi hospitals. A cross-sectional study was conducted among 191 food service staff from seven different hospitals in Dhaka and Chattogram from October 2021 to March 2022 using pretested questionnaires. Multiple linear regression was used to identify the factors associated with the food safety knowledge, attitudes and practices. The findings showed moderate knowledge but high levels of attitudes and practices of food safety among hospital food handlers. Food safety knowledge was significantly higher among males, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations. Moreover, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations had more positive attitudes and better practices regarding food safety. Hospital management should consider these factors for enhancing food handlers' knowledge and increase training and supervision on food safety practices to reduce foodborne diseases and outbreaks
Unmanned Aerial Vehicles: A Revolution in the Making
Since the flight of a kite by some Chinese, thousands of years ago, the UAVs have developed to the level of unleashing immeasurable destruction even without endangering the life of the „man in the loop‟. This paper traces the history of the drones in the modern times while focusing on the American utilization of the UAVs in the wars of the twenty-first century. Drones basically address the „friction‟ element of the war. While analyzing the technical aspects of the UAVs, the article assesses the revolution these have brought in the conduct of the warfare. There are issues of collateral damage being labeled against the use of UAVs, but there is no denying the fact that these are the best weapons available in the arsenal to minimize the number of civilian casualties – as compared with the manned aircrafts and the casualties caused by the missiles fired from the aircraft carriers at times stationed hundreds of miles away. Pilotless target aircraft (PTA), Reconnaissance UAVs, and Strike UAVs or UCAVs are the three main types of Drones according to their function. The advantages of the UAVs over the manned aircrafts are the performance of dull, dirty, and dangerous work, their development and use being economical, their tactical advantage of not endangering the life of the controller, and most recently their use in the civilian arena like the flood relief activities, monitoring of the borders, reconnaissance of the areas after accidents or natural disasters, etc. Biggest challenges in the development of the drones are enhancing the endurance and autonomy of the UAVs, in-flight refueling, increasing the payload capacity, having less numbers of satellites, and most importantly the issues related with the international law and the attached ethical issues. With the successful tests of Burraq, Pakistan has also joined the club of the states developing the UAVs and the race is still „on‟
The Application of the Extended Poincaré Plot in the Analysis of Physiological Variabilities
The Poincaré plot is a geometrical technique used to visualize and quantify the correlation between two consecutive data points in a time-series. Since the dynamics of fluctuations in physiological rhythms exhibit long-term correlation and memory, this study aimed to extend the Poincaré plot by calculating the correlation between sequential data points in a time-series, rather than between two consecutive points. By incorporating this so-called lag, we hope to integrate a temporal aspect into quantifying the correlation, to depict whether a physiological system holds prolonged association between events separated by time. In doing so, it attempts to instantaneously characterize the intrinsic behavior of a complex system. We tested this hypothesis on three different physiological time-series: heart rate variability in patients with liver cirrhosis, respiratory rhythm in asthma and body temperature fluctuation in patients with cirrhosis, to evaluate the potential application of the extended Poincaré method in clinical practice. When studying the cardiac inter-beat intervals, the extended Poincaré plot revealed a stronger autocorrelation for patients with decompensated liver cirrhosis compared to less severe cases using Pearson’s correlation coefficient. In addition, long-term variability (known as SD2 in the extended Poincaré plot) appeared as an independent prognostic variable. This holds significance by acting as a non-invasive tool to evaluate patients with chronic liver disease and potentially facilitate transplant selection as an adjuvant to traditional criteria. For asthmatics, employing the extended Poincaré plot allowed for a non-invasive tool to differentially diagnose various classifications of respiratory disease. In the respiratory inter-breath interval analysis, the receiver operating characteristic (ROC) curve provided evidence that the extension of the Poincaré plot holds a greater advantage in the classification of asthmatic patients, over the traditional Poincaré plot. Lastly, the analysis of body temperature from patients using the extended Poincaré plot helped identify inpatients from outpatients with cirrhosis. Through these analyses, the extended Poincaré plot provided unique and additional information which could potentially make a difference in clinical practice. Conclusively, the potential use of our work lies in its possible application of predicting mortality for the organ allocation procedure in patients with cirrhosis and non-invasively distinguish between atopic and non-atopic asthma
Vascular Endothelial Growth Factor Receptor-2 Couples Cyclo-Oxygenase-2 with Pro-Angiogenic Actions of Leptin on Human Endothelial Cells
The adipocyte-derived hormone leptin influences the behaviour of a wide range of cell types and is now recognised as a pro-angiogenic and pro-inflammatory factor. In the vasculature, these effects are mediated in part through its direct leptin receptor (ObRb)-driven actions on endothelial cells (ECs) but the mechanisms responsible for these activities have not been established. In this study we sought to more fully define the molecular links between inflammatory and angiogenic responses of leptin-stimulated human ECs../Akt/COX-2 signalling axis is required for leptin's pro-angiogenic actions and that this is regulated upstream by ObRb-dependent activation of VEGFR2. These studies identify a new function for VEGFR2 as a mediator of leptin-stimulated COX-2 expression and angiogenesis and have implications for understanding leptin's regulation of the vasculature in both non-obese and obese individuals
