Tailoring MIL-100(Fe)-derived catalyst for controlled carbon dioxide conversion and product selectivity.

Here in, we are reporting the effect of the catalyst particle size on the catalytic activity and product selectivity by understanding the strength of the interaction between the active catalyst and the reactants (CO and H). In this regard, two catalytic systems having different active catalyst particle sizes and support surface areas were synthesized using metal-organic frameworks (MOF) (MIL-100(Fe)) having two crystal size ranges as sacrificial templates. The active catalyst having smaller nanoparticles exhibited greater chemisorption of hydrogen (Fe-H bond), resulting in heightened selectivity for paraffin due to hydrogenation of re-adsorbed olefins.

Optimization of isotropic MoS/PES membranes for efficient treatment of industrial oily wastewater.

Elimination of tiny oil droplets nearly miscible with wastewater can be realized using membrane technology through ultrafiltration. The novelty of this work was to blend different phases of molybdenum disulfide (MoS) in isotropic polyethersulfone (PES). We prepared isotropic PES membranes by optimizing nonsolvent vapour-induced phase separation (VIPS).

White sustainable luminescent determination of nifuroxazide using nitrogen-sulphur co-doped carbon quantum dots nanosensor in bulk and various pharmaceutical matrices.

Nifuroxazide (NFX) is an antimicrobial agent that is frequently used as an intestinal antiseptic and recently was proven to have anticancer properties. This work employs the use of nitrogen and sulphur co-doped carbon quantum dots (NSC-dots) luminescent nanoparticles to propose a highly sensitive, sustainable, white and green spectrofluorometric method for NFX detection in bulk and pharmaceutical dosage forms. l-Cysteine and citric acid were the precursors to synthesize water soluble NSC-dots by a quick and environmentally-friendly hydrothermal process.

RME's phenolic profile was identified by liquid chromatography coupled to mass spectroscopy (LC-ESI/MS/MS) technique. A tentative identification of 21 phenolic metabolites from the extract was performed.

A case report of severe hyponatremia secondary to Paxlovid-induced SIADH.

Nirmatrelvir-ritonavir (Paxlovid) is a brand-new oral antiviral medication for treating mild to severe COVID-19. The Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for ritonavir-nirmatrelvir on December 22, 2021, to treat COVID-19. We describe a case of mild COVID-19 infection who developed severe hyponatremia following the administration of Paxlovid.

Ivabradine effects on COVID-19-associated postural orthostatic tachycardia syndrome: a single center prospective study.

Background: A wide range of cardiac arrhythmias were reported in the setting of active infection or as a complication of COVID-19. The main pathophysiology can be attributed to dysautonomia or autonomic nervous system dysfunction. Postural orthostatic tachycardia syndrome (POTS) is a complex, multisystemic disorder affecting usually younger age with tachycardia at rest or with minimal effort being the main symptom.

Ivabradine effects in hospitalized acute heart failure patients: a single center retrospective study.

Background: An increased heart rate (HR) is deleterious in patients with decompensated heart failure. Ivabradine, an HR lowering agent which acts by inhibiting the I current in the sinoatrial node, is indicated for chronic heart failure with reduced ejection fraction. However, data regarding the safety and efficacy of ivabradine in acute decompensated heart failure is limited.
