Elizabeth Fistein, David Cruise Malloy
As healthcare professionals we are committed to the efficient and effective operation of our institutions. Bureaucratic structures, rules, regulations, policies, and of course, measurements, are the tools-at-hand. While there is nothing inherently pernicious about efficient, effective, and measured institutions, we argue what is critically missing in this environment is humanity and authenticity at the cost of meaningful work. The solutions we offer are found in the realm of philosophy and in particular that branch of philosophy that deals with first principles - what is a nurse; what is a patient; what is a hospital?...

Over the past decade, the Patients as Partners Movement has spread throughout healthcare systems across Canada. This movement aims to overcome the paternalistic approach, where the system and its providers act for or deliver services to the patient. Instead, decision-making at all levels is to be shared with the patient. Delivering patient- and family-centred care is the goal of the Patients as Partners Movement and authentic engagement is at its core. This article aims to explore the link between the Patients as Partners Movement and authentic engagement...

To establish a method for the identification of five species and one variety of medicinal plants from Diospyros, their leaf veins, epidermis, anatomic and powder characters were observed and compared with macro-morphological and microscopic methods. The results indicated the differences of secondary and tertiary veins among those Diospyros species. The single cell non-glandular hair and glandular hair exist in most species' epidermis while stone cells were only found in the leaf powders of two species. Through the study, the main differences of leaf macro- and micro-morphology of these species were obtained and practical keys were also established, which can provide scientific base not only for identification of these species during their vegetative stages, but also for accuracy authentication of the source of Kaki Folium...

It is the declared objective of the Falsified Medicines Directive 2011/62/EU to further improve the protection of patients from falsified pharmaceuticals. Therefore, it stipulates measures based on which falsified medicines in the supply chain can be more easily identified. This is the European legislature's reaction to an increase in falsified medicines. The EU Falsified Medicines Directive aims to create a uniform, standardized solution for protection from falsified drugs. From 9 February 2019 onward (according to the EU Regulation No...

The biological material, chitin, is present in nature in three allomorphic forms: α, β and γ. Whereas most studies have dealt with α- and β-chitin, only few investigations have focused on γ-chitin, whose structural and physicochemical properties have not been well delineated. In this study, chitin obtained for the first time from the cocoon of the moth (Orgyia dubia) was subjected to extensive physicochemical analyses and examined, in parallel, with α-chitin from exoskeleton of a freshwater crab and β-chitin from cuttlebone of the common cuttlefish...

Seeking an effective electronic synapse to emulate biological synaptic behavior is fundamental for building brain-inspired computers. An emerging two-terminal memristor, in which the conductance can be gradually modulated by external electrical stimuli, is widely considered as the strongest competitor of the electronic synapse. Here, we show the capability of TiOx/Al2O3-based memristor devices to imitate synaptic behaviors. Along with analog resistive switching performances, the devices replicate the bio-synapse behaviors of potentiation/depression, short-term-plasticity, and long-term-potentiation, which show that TiOx/Al2O3-based memristors may be useful as electronic synapses...

REVIEW
Justin T Brady, Molly E Kelly, Sharon L Stein
Social media is a source of news and information for an increasing portion of the general public and physicians. The recent political election was a vivid example of how social media can be used for the rapid spread of "fake news" and that posts on social media are not subject to fact-checking or editorial review. The medical field is susceptible to propagation of misinformation, with poor differentiation between authenticated and erroneous information. Due to the presence of social "bubbles," surgeons may not be aware of the misinformation that patients are reading, and thus, it may be difficult to counteract the false information that is seen by the general public...

Pichia pastoris has been one of the most successful heterologous overexpression systems in generating proteins for large-scale production through high-cell-density fermentation. However, optimizing conditions of the large-scale high-cell-density fermentation for biochemistry and industrialization is usually a laborious and time-consuming process. Furthermore, it is often difficult to produce authentic proteins in large quantities, which is a major obstacle for functional and structural features analysis and industrial application...

Alternative matrices play a major role in postmortem forensic toxicology, especially if common matrices (like body fluids or hair) are not available. Incorporation of illicit and medicinal drugs into non-mineralized dental biofilm (plaque) seems likely but has not been investigated so far. Analysis of plaque could therefore extend the spectrum of potentially used matrices in postmortem toxicology. For this reason, a rapid, simple and sensitive method for the extraction, determination and quantification of ten drugs of abuse from plaque using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed and fully validated...

Sugarcane honey (SCH) is one of the Madeira Island products par excellence and it is now popular worldwide. Its sui generis and peculiar sensory properties, explained by a variety of volatile compounds including furanic derivatives (FDs), arise mainly from manufacturing and storage conditions. A simple high-throughput approach based on semi-automatic microextraction by packed sorbent (MEPS) combined with ultra-high performance liquid chromatography (UHPLC) was developed and validated for identification and quantification of target FDs in sugarcane honey...

7α-hydroxy-4-cholesten-3-one (C4) is an oxidative enzymatic product of cholesterol metabolism via cholesterol 7α-hydroxylase, an enzyme also known as cholesterol 7-alpha-monooxygenase or cytochrome P450 7A1 (CYP7A1). C4 is a stable intermediate in the rate limiting pathway of bile acid biosynthesis. Previous studies showed that plasma C4 levels correlated with CYP7A1 enzymatic activity and could serve as a biomarker for bile acid synthesis. Here we developed and qualified a simple and robust high-throughput method using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) to quantify C4 in rat and monkey plasma...

Falsifying Global Navigation Satellite System (GNSS) data with a simulator or with a fake receiver can have a significant economic or safety impact in many transportation applications where Position, Velocity and Time (PVT) are used to enforce a regulation. In this context, the authentication of the source of the PVT data (i.e., the GNSS receiver) is a requirement since data faking can become a serious threat. Receiver fingerprinting techniques represent possible countermeasures to verify the authenticity of a GNSS receiver and of its data...

OBJECTIVE: hnRNPA1 (heterogeneous nuclear ribonucleoprotein A1) plays a variety of roles in gene expression. However, little is known about the functional involvement of hnRNPA1 in vascular smooth muscle cell (VSMC) function and neointima hyperplasia. In this study, we have attempted to investigate the functional roles of hnRNPA1 in the contexts of VSMC function, injury-induced vessel remodeling, and human atherosclerotic lesions, as well as discern the molecular mechanisms involved. APPROACH AND RESULTS: hnRNPA1 expression levels were consistently modulated during VSMC phenotype switching and neointimal lesion formation induced by wire injury...
