Ethanol Inhalation as a Method to Denature the Spike Protein of SARS-CoV-2.

The SARS-CoV-2 virus caused the 2019 COVID pandemic by infecting almost eight hundred million people worldwide. Because it was a new viral infection, there were no vaccines or small molecule medications that could prevent or treat the disease.  This chapter provides some details for an obscure treatment for COVID-19, that has decades of anti-viral activity data both in vitro and in vivo in the literature.

Lessons learnt from the implementation of the Covid-19 vaccination programme in the Southwest of England.

Background: Vaccination remains one of the most successful public health interventions in preventing severe disease and death. The roll-out of Covid-19 vaccination programmes has helped protect billions of people around the world against Covid-19. Most of these programmes have been unprecedented in terms of scale and resources, and have been implemented at times of significant humanitarian crisis.

Sporadic Creutzfeldt-Jakob Disease Initially Presenting With Posterior Reversible Encephalopathy Syndrome: A Case Report.

Introduction: Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal neurodegenerative condition caused by prion proteins. Cortical and subcortical diffusion-weighted imaging restriction on magnetic resonance imaging (MRI) is associated with sCJD. Posterior reversible encephalopathy syndrome (PRES) results from impaired vessel autoregulation due to an identifiable trigger, which is associated with subcortical fluid-attenuated inversion recovery changes on MRI.

Vaporization, bioactive formulations and a marine natural product: different perspectives on antivirals.

This article examines three aspects of antivirals, such as hydroxychloroquine, chloroquine, and remdesvir, as they might relate to the treatment of a viral infection such as COVID-19: (i) the use of vaporization for the delivery of antivirals, with the bulk constituents having mild antiviral efficacy; (ii) the application of a marine natural product extract as opposed to a single molecule as an antiviral agent; and (iii) a counter intuitive approach to formulation that is, in part, based on delivering multiple species that fall into three categories: building blocks for the virus to accelerate replication; an energy source for the infected cell to boost its immune response; and the species that antagonize or provide toxicity to the virus.

A Copper-Paclitaxel crystal; a medicinally active drug delivery platform.

Pharmaceutical interventions for weight-loss maintenance: no effect from cabergoline.

Background: Weight regain is a major limitation to successful weight maintenance following weight loss. Observational studies suggest that stimulation of dopamine receptors in the central nervous system is associated with weight loss and inhibition of weight gain. Our objective was to test the hypothesis that dopamine agonist treatment would prevent weight regain following acute weight loss in individuals with obesity.

Demonstration of universal parametric entangling gates on a multi-qubit lattice.

We show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors. By inducing coherent population exchange between adjacent qubits under frequency modulation, we implement a universal gate set for a linear array of four superconducting qubits. An average process fidelity of ℱ = 93% is estimated for three two-qubit gates via quantum process tomography.
