A new insight into non-covalent interactions in 1,4-disubstituted 1H-1,2,3-triazole: synthesis, X-ray structure, DFT calculations, in vitro lipoxygenase Inhibition (LOX) and in silico studies
Present work deals with the synthesis, characterization, structural properties and in silico studies of ethyl 6-(4-(cyclohexylmethyl)-1H-1,2,3-triazol-1-yl)pyridine-3-carboxylate (1). The synthesized derivative was characterized by spectroscopic as well as single crystal XRD technique. The structure reveals weak non-covalent contacts such as C-H···π, lone pair···π and π···π stacking interactions along with C-H···O and C-H···N hydrogen bonds to form the supramolecular assembly. A detailed analysis of the intermolecular interactions was performed by using the Hirshfeld surface analysis and energy framework calculations, indicating that the dispersion energy is dominant over the electrostatic one in all the structural dimer studied. In addition, the intermolecular interactions have been characterized using the quantum theory of “atoms in molecules”, molecular electrostatic potential (MEP) and the non-covalent interaction plot (NCI plot) index analysis. Compound displayed the IC50 value of IC50 = 37.40 μM in comparison to reference drug indomethacin (IC50 = 48.25 μM) against lipoxygenase (LOX). Docking studies revealed important interactions and binding energy of the compound in comparison with the standard drugs used.Fil: Ahmed, Muhammad Naeem.

The Relation Between Interpersonal Relationship Satisfaction and Spiritual Well-Being in Adults
The purpose of the study is a correlational analysis between interpersonal relationship satisfaction and spiritual well-being in adults. This study is a quantitative, correlational study. Data were collected through purposive sampling technique from different institutes and organizations. The sample size of the study was sample (n = 200). The age ranges of participants were 20–35 years. Two scales, Spirituality Index of Well-Being (SIWB) and Relationship Assessment Scale (RAS-G), were used for data collection and the data was analyzed statistically. The analysis was carried out by the statistical tests correlation test, t-test and ANOVA. It was revealed through this study that interpersonal relationship satisfaction and Spiritual well-being were positively correlated with each other. Additionally, it was found that married adults have strong spiritual well-being and interpersonal relationships than unmarried adults. However, there was no gender significance difference was found. Moreover, it was revealed that the spiritual well-being and interpersonal relation strength is higher in upper ages then in lower ages
Energy Efficient Schemes for Wireless Sensor Network (WSN)
Conservation of energy is the main design issue in wirelesssensor network (WSN) which is usually available at each node. Althoughdifferent solutions have been introduced for typical wireless networks,cellular networks, MANET, and other short-range wireless local areanetworks, yet they are not often much feasible for a large scale WSN.For this purpose, multiple mobile sink nodes can be deployed to increasethe life of sensor network. The purpose can be achieved by splitting thelife time into equal time interval known as rounds. Similarly, byemploying multiple sink nodes can also make the sensor network moreenergy efficient. Another way to make the sensor network energyefficient is to logically divide the deployment area into static clusters. Byadopting the strategy of static cluster, energy consumption can beminimized. The two major wireless standards used by WSN are 802.15.4and Zigbee [1],[2] .They are low-power protocols. Maximum distance isaround 100m (at 2.4 GHz). However, performance is an issue. In orderto assure the Wireless sensor network (WSN)s survivability and increasethe lifetime of network in such environments, various energy efficiencyschemes have been proposed in the literature. Energy is a valuablecommodity in wireless networks due to the limited battery of the handydevices. The energy problem becomes stiffer in ad-hoc WSN)
An Analysis of the Relationship between Inflation and Gold Prices: Evidence from Pakistan
In this study, we formulate a new inflation equation to capture the potential effects of gold and stock prices on inflation in Pakistan. We aim to assess the inflation-hedging properties of gold compared to other assets such as real estate, stock exchange securities, and foreign currency holdings. Applying time-series econometric techniques (cointegration and vector error correction models) to data for 1960–2010, we find that gold is a potential determinant of inflation in Pakistan. On the other hand, it also provides a complete hedge against unexpected inflation. Real estate assets are more than a complete hedge against expected inflation, although stock exchange securities outperform gold and real estate as a hedge against unexpected inflation. Foreign currency proves to be an insignificant hedge against inflation. Given the dual nature of the relationship between gold and inflation, it is increasingly important for the government to monitor and regulate the gold market in Pakistan. Moreover, stock market investment should be encouraged by the government given that asset price inflation does not pose a critical problem for Pakistan as yet
Effect of Prone Positioning in Patients with Moderate COVID-19 Pneumonia Admitted to Ward at a Tertiary Care Hospital
COVID -19 pneumonia can progress to severe disease in 5% of patients requiring intensive care management, which can put an excessive burden on health care systems. Prone positioning has been shown to improve oxygenation and decrease lung injury in patients with COVID-19 pneumonia and can be used as an adjunctive treatment to delay intubation. The objective of this study is to assess the effect of prone positioning in patients admitted to the COVID ward, with Moderate COVID-19 Pneumonia. This experimental study was conducted at Liaquat National Hospital. A quasi-experimental study design was applied. Patients with hypoxemia SpO2 < 94% were assisted to prone and semi-prone for up to 2 hours at a time for multiple sessions. Parameters like SaO2, PaO2/FiO2, hours of proning and changes and X-rays were recorded daily and pre and post-intervention values were compared. Paired t-test and Wilcoxon sign test were used to compare continuous parameters. A two-tailed p-value less than 5% of the level of significance was defined as statistically significant. 20 patients fulfilling the inclusion criteria were enrolled. Median hours of prone positioning were 48.5. The median hospital stay was 7.5 days. At baseline, mean PaO2/FiO2 ratio was 342±91.87 and at the time of discharge, it was 412.30±105.97 which is a statistically significant improvement from baseline (p=0.040). 50% of patients showed improvement in X-rays. One patient was intubated and all the patients were discharged. The sample collected in the current showed that prone positioning is a safe and feasible approach to improve oxygenation in moderate-severe COVID-19 pneumonias. However, studies with a larger sample size are recommended to further verify the findings of this study
Resource Dimensions Influencing Technological Appropriation in ESP Writing Instruction
The objective of this study is to investigate the role of the material and immaterial, social, and educational resources in the appropriation of digital and AI during English to Specific Purposes (ESP) writing instructions. Informed by van Dijk’s Resource and Appropriation Theory (RAT), the study will employ quantitative correlational survey research design and target ESP writing instructors who responded to a structured Likert-scale questionnaire. The findings reveal that motivation and teacher’s autonomy are not the only factor to define technological appropriation in ESP settings but is also shaped by the access to institutional infrastructural resources, training facilities, and participatory decision-making environments. Material and social resources emerged as central facilitators, where immaterial resources like autonomy and flexibility remained in the periphery, but played a significant supporting role. It was demonstrated that educational abilities like the ability to adapt writing instruction through the usage of the digital tools are dependent on the access of materials and the collaborative institutional cultures. This paper reiterates that ESP writing training that necessitates task-specific and discipline-relevant instruction cannot be simply a matter of individual ingenuity it must be backed up by systemic support. The results support an integrated approach to digital integration in ESP, which is based on balanced infrastructure, empowerment, and professional development to provide technological equity in the process
