Facile and cost-effective NiO/MgO-SiO composites for efficient oxygen evolution reaction and asymmetric supercapacitor systems.

Biomass waste from grapefruit peel extract was used for the preparation of MgO-SiO composites in order to develop effective electrocatalytic composites based on NiO/MgO-SiO. The MgO-SiO composites were subsequently deposited with NiO using a modified hydrothermal method. The synthesized materials were analyzed to investigate their morphology, crystal structure, chemical composition, functional group, and optical band gap.

Facile and ecofriendly green synthesis of CoO/MgO-SiO composites towards efficient asymmetric supercapacitor and oxygen evolution reaction applications.

The development of low-cost, eco-friendly, and earth-friendly electrode materials for energy storage and conversion applications is a highly desirable but challenging task for strengthening the existing renewable energy systems. As part of this study, orange peel extract was utilized to synthesize a magnesium oxide-silicon dioxide hybrid substrate system (MgO-SiO) for coating cobalt oxide nanostructures (CoO) hydrothermal methods. A variety of MgO-SiO compositions were used to produce CoO nanostructures.

Do collaterals to infarct bed in STE-ACS patients undergoing emergent percutaneous coronary revascularization matter? An assessment of a prospective pool for in-hospital course.

Background: Limited data exist on the role of coronary collaterals circulation (CCC) in patients with ST-elevation acute coronary syndrome (STE-ACS). This study aimed to assess CCC and the in-hospital course of patients with CCC undergoing primary percutaneous coronary intervention (pPCI).

Methods: The study included consecutive STE-ACS patients undergoing pPCI.

Immediate in-hospital outcomes after percutaneous revascularization of acute myocardial infarction complicated by cardiogenic shock.

Background: Cardiogenic shock (CS) is a life-threatening complication of acute myocardial infarction with high morbidity and mortality rates. Primary percutaneous coronary intervention (PCI) has been shown to improve outcomes in patients with CS.

Aim: To investigate the immediate mortality rates in patients with CS undergoing primary PCI and identify mortality predictors.

One-year major adverse cardiovascular events among same-day discharged patients after primary percutaneous coronary intervention at a tertiary care cardiac centre in Karachi, Pakistan: a prospective observational study.

Objective: Knowledge regarding the short-term outcomes after same-day discharge (SDD) post primary percutaneous coronary intervention (PCI) is lacking. In this study, we evaluated 1-year major adverse cardiovascular events (MACE) among SDD patients after primary PCI.

Design: 1-year follow-up analysis of a subset of patients from an existing prospective cohort study.

Zwolle Risk Score for Safety Assessment of Same-day Discharge after Primary Percutaneous Coronary Intervention.

Objectives: The Zwolle risk score (ZRS) has been considered to be a useful tool for the systematic evaluation of patients for early discharge after primary percutaneous coronary intervention (PCI). Therefore, aim of this study was to evaluate the clinical utility of ZRS for the same-day discharge strategy after primary PCI at a tertiary care cardiac center of Karachi, Pakistan.

Methods: This study was conducted at a tertiary care cardiac center between August 2019 and July 2020.

Concentrations of Lead, Mercury, Arsenic, Cadmium, Manganese, and Aluminum in the Blood of Pakistani Children with and without Autism Spectrum Disorder and Their Associated Factors.

Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with early onset in utero or childhood. Environmental exposure to six metals (Pb, Hg, As, Cd, Mn, Al) is believed to be associated with ASD directly or interactively with genes. : To assess the association of ASD among Pakistani children with the six metals and genotype frequencies of three GST genes (, , ).

Psychosocial Impact of COVID-19 on Healthcare Workers at a Tertiary Care Cardiac Center of Karachi Pakistan.

Objectives: Aim of this study was to determine the depression, stress, and anxiety level among healthcare workers working at a tertiary care cardiac center of Karachi Pakistan during COVID-19 pandemic.

Methods: This survey was conducted at the National Institute of Cardiovascular Disease (NICVD), Karachi, Pakistan. Participants of the study were fulltime employees of hospital.

Synthesis of Heart/Dumbbell-Like CuO Functional Nanostructures for the Development of Uric Acid Biosensor.

It is always demanded to prepare a nanostructured material with prominent functional properties for the development of a new generation of devices. This study is focused on the synthesis of heart/dumbbell-like CuO nanostructures using a low-temperature aqueous chemical growth method with vitamin B as a soft template and growth directing agent. CuO nanostructures are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques.
