Abstract
The present study was aimed to evaluate the antioxidant potential and inhibitory effect ofCannabis sativa and Morus nigra against lipid peroxidation in goat brain and liver homogenates. The formation of free radicals, highly reactive oxygen species (ROS) and reactive nitrogen species (RNS) is a normal metabolic process for cellular signaling and countering the antigens. However, they may cause serious damage if they produced at amplified tolls. In addition, metabolic disorders also serve as sources of these reactive species. Although the issue can be addressed through supplements and other phytochemicals. In this study, two plant species were evaluated for their biological potential by employing a spectrum of antioxidant assays. The antioxidant activity was performed by lipid peroxidation assay. The water extract prepared from leaves of Cannabis sativa and Morus nigra showed significant (P<0.05) inhibition as compared to control i.e., 522.6±0.06 and 659.97±0.03 µg/mL against iron-induced lipid peroxidation in goat brain homogenate while the inhibitions were 273.54±0.04 and 309.18±0.05 µg/mL against nitroprusside induced lipid peroxidation of the brain. The iron and nitroprusside induced lipid peroxidation was also significantly inhibited by leaf extracts of Cannabis sativa and Morus nigra in liver homogenates such as 230.63±0.52 and 326.91±0.01 µg/mL (iron-induced) while 300.47±0.07 and 300.47±0.07 µg/mL (nitroprusside induced), respectively. The extracts of Cannabis sativa extract showed promising activity (96.04±0.060%) against DPPH radicals while Morus nigra showed a moderate activity (34.11±0.120%). The results suggest that different accessions ofCannabis sativa and Morus nigra are a potential source of antioxidants and have a therapeutic effect against disease induced by oxidative stress and hence can be used for novel drug discovery and development.

Abstract
This article discusses the conversion of electrodeposited iodine to polyiodides within the nanopores of carbon electrodes that affect the performance of iodide electrolyte-based electrochemical cells. Here, carbon electrodes have been polarized in aqueous sodium iodide electrolyte to store charge in the form of solid iodine via highly reversible reaction (2I-⇌I2+2e-). The stored iodine within the pores interacts with free iodide ions present in the bulk electrolyte via comproportionation reactions leading to polyiodide (I3 - and I5 -) formations. By tuning the mass asymmetry of carbon electrodes in hybrid cells and using the in-situ Raman spectroscopy on positive battery electrode, we show the influence of iodine/polyiodides equilibrium shifts on the self-discharge and voltage rebounds during open circuit conditions. This study provides insights into the charging mechanisms of carbon electrodes for iodine-based hybrid supercapacitors and battery systems.

Abstract
BACKGROUND Secreted Frizzled-Related Protein 4 (SFRP4) is a glycoprotein that acts as a competitor of both canonical and non-canonical Wnt pathways. SFRP4 is mostly expressed in ovary and plays a significant role as a target molecule to cure ovarian carcinoma. OBJECTIVE Multiple chemical agonists are being used to cure ovary melanoma. We are interested in theoretically analyzing the compounds through computational approaches for their potential inhibitory effects against SFRP4. METHODS Compounds were sketched in Chemsketch drawing tool and minimized through chimera tool. Because the crystal structure of SFRP4 is not available in Protein Data Bank, homology modeling approach was used to predict Three-Dimensional (3D) crystal structure of SFRP4. Moreover, multiple computational approaches such as molecular docking and Molecular Dynamic (MD) simulations along with various online tools were employed to screen the best inhibitor against ovary melanoma. RESULTS The docking results showed that 1d and 1e compounds revealed significant binding energy values (-9.10 and -9.00 kcal/mol, respectively) compared with the standard drugs such as cis-platin and docetaxel (-3.30, -10.80 kcal/mol), respectively. Moreover, MD simulation results showed that 1d has little fluctuations throughout the simulation period as depicted by the root mean square deviation and root mean square fluctuation graphs. CONCLUSION The present in-silico study provides a deeper insight into the structural attributes of 1d compound and its overall molecular interactions against SFRP4 and gives a hypothetical gateway to use this compound as a potential inhibitor against ovarian carcinoma.

Abstract
Activated carbons (ACs) have been prepared from chemical treatment of walnut shells (WS) precursor at various temperatures (400‒800 °C) by using phosphoric acid (H3PO4) as activating agent. Influence of activation temperature on the porosity development and capacitive properties of resulting carbons was investigated. Thermal post-treatment of carbons previously activated at moderate temperature, e.g. 400 °C allowed further structural and porosity modification. Then, these carbons were investigated by scanning electron microscopy, Raman spectroscopy, energy-dispersive X-ray spectroscopy, electrochemical techniques and low temperature nitrogen adsorption exhibiting high BET specific surface area of approximately 2100 m2 g-1 and a total pore volume up to 1.3 cm3 g-1. Carbon material obtained through activation by H3PO4 at 400 °C and post-treated at 800 °C was used to make electrodes which were implemented to realize AC/AC capacitor using 1 mol L-1 Li2SO4. The electrochemical capacitor demonstrated high capacitance of 123 F g-1 per mass of one electrode, reduced cell resistance and stable capacitance for 5000 galvanostatic charge/discharge cycles at 1.0 A g-1.

Abstract
This study assessed the effect of implementation of active infection control and surveillance on the occurrence of device-associated infections (DAIs) in a paediatric intensive care unit (PICU) from 2012 to 2015. There were 1378 patients, equating to 4632 patient-days, on the PICU, and 29 DAI episodes, giving an incidence rate of 2.1% and an incidence density rate of 6.26 per 1000 patient-days. The rates of central-line-associated bloodstream infections, ventilator-associated pneumonia and catheter-related urinary tract infections were 7/1000 central-line-days, 1.17/1000 ventilator-days and 0.24/1000 urinary-catheter-days, respectively. Despite the overall low rate of DAIs in the PICU, there was a relatively high rate of central-line-associated bloodstream infections.

Abstract
Abstract
A closed loop auto control system has been developed and implemented at the Pakistan Research Reactor-2 (PARR-2). For interfacing of the site signals with a computer, a data acquisition card was employed. The system utilizes nine signals and, on their basis, carries out continuous on-line analysis, maintaining safe operation. On-line reactivity measurement is included in this software. Also, it generates control signals for keeping the reactor at the desired power level in auto-mode round-the-clock without human intervention. In case of abnormal conditions for either power or temperature or radiation level, alarms are initiated and if their levels reach beyond prescribed safe operation regime, automatic shutdown sequence is initiated. The control system has been thoroughly tested for various postulated scenarios. The test results have been in good agreement with the expected response.
