Andrea Dörries
BACKGROUND: In recent times - also due to new laws - a good "indication quality" has been called for. The aim of this paper is to contribute to the debate about "indication quality" by looking into the meaning of the term "indication" as well as the meaning of an adequate understanding of quality. METHODS: Initially, a conceptual analysis is made of how indication is an integral part of the therapeutic decision-making process between physician and patient, in which, next to evidence-based elements, also normative elements are included (step 1)...

Closed-loop drug delivery promises autonomous control of pharmacotherapy through the continuous monitoring of biomarker levels. For decades, researchers have strived for portable closed-loop systems, capable of treating ambulatory patients with chronic conditions such as diabetes mellitus. After years of development, the first of these systems have left the laboratory and entered commercial use. This long-awaited advance reflects recent development of chronically stable implantable biosensors, able to accurately measure biomarker levels in vivo...

Samarendra Das, Anil Rai, D C Mishra, S N Rai
Selection of informative genes from high dimensional gene expression data has emerged as an important research area in genomics. Many gene selection techniques have been proposed so far are either based on relevancy or redundancy measure. Further, the performance of these techniques has been adjudged through post selection classification accuracy computed through a classifier using the selected genes. This performance metric may be statistically sound but may not be biologically relevant. A statistical approach, i...

Advances in Endoscopic Eradication Therapy for Barrett's Esophagus associated neoplasia have resulted in a significant paradigm shift in diagnosis and management of this complex disease. A robust body of literature critically evaluating outcomes of resection and ablative strategies has allowed gastroenterologists to make quality, evidence based decisions for their patients. Despite this progress, there are still many unanswered questions and challenges that remain. Ultimately, identification of a cost-effective screening modality, biomarkers for risk stratification, and strides to eliminate post surveillance endoscopy after EET are essential to reach our long term goal for eradication of esophageal adenocarcinoma...

Debasish Kumar Ghosh, Ajit Roy, Akash Ranjan
Protein aggregates result from altered structural conformations and they can perturb cellular homeostasis. Prevention mechanisms, which function against protein aggregation by modulatory processes, are diverse and redundant. In this study, we have characterized Huntingtin interacting protein K (HYPK) as a global aggregation-regulatory protein. We report the mechanistic details of how HYPK's aggregation-prone regions allow it to sense and prevent other toxic protein's aggregation by forming unique annular-shaped sequestration complexes...

Nowadays, food security is a vital issue and antimicrobial packaging could play an important role in this matter. In this regard, Salvia macrosiphon seed mucilage (SSM) and nanoclay, as new sources for the production of food-grade edible films were investigated. These edible films were prepared by incorporation of SSM with glycerol and different percentage of nanoclay. Upon addition of nanoclay up to 2% physical, mechanical and thermal properties were considerably improved and the composite films showed the lowest water vapor permeability (WVP), as well as highest elongation at break and tensile strength...

BACKGROUND: Deep brain stimulation of the subthalamic nucleus (STN DBS) is known to increase response speed and lower response accuracy in Parkinson's disease (PD) patients. It has been proposed that this speed-accuracy tradeoff is due to enhanced sensitivity of the motor system to sensory information. An alternative possibility is that this effect is due to weakened suppressive processes. The two alternative interpretations can be tested by analyzing the electromyographic activity (EMG) of the response agonists when the patients perform conflict reaction time tasks...

HCoV-229E spike (S) protein mediates virion attachment to cells and subsequent fusion of the viral and cellular membranes. This protein is composed of an N-terminal receptor-binding domain (S1) and a C-terminal trans-membrane fusion domain (S2). S2 contains a highly conserved heptad repeat 1 and 2 (HR1 and HR2). In this study, the HRs sequences were designed and connected with a flexible linker. The recombinant fusion core protein was crystallized and its structure was solved at a resolution of 2.45 Å. Then we characterized the binding of HR1s and HR2s via both sequence alignment and structural analysis...

Here, we demonstrate that the use of single-molecule centroid localization algorithm can improve the accuracy of fluorescence binding assays. Two major artifacts in this type of assays, i.e., non-specific binding events and optically overlapping receptors, can be detected and corrected during analysis. The effectiveness of our method was confirmed by measuring two weak biomolecular interactions, the interaction between the B1 domain of streptococcal protein G (pGB1) and immunoglobulin G (IgG), and the one between double-stranded DNA (dsDNA) and the Cas9-RNA complex with limited sequence matches...

Visible light photocatalysis has evolved over the last decade into a widely used method in organic synthesis. For many important transformations, such as cross-coupling reactions, alpha-amino functionalizations, cycloadditions, ATRA reactions, or fluorinations, photocatalytic variants have been reported. In this review, we try to compare classical and photocatalytic procedures for selected classes of reactions and highlight their advantages and limitations. In many cases, the photocatalytic reactions proceed at milder reaction conditions, typically at room temperature, and stoichiometric reagents are replaced by simple oxidants or reductants, like air oxygen or amines...

Anneyce Knight
This article presents a snapshot of my experience of being a nurse who became a service user with breast cancer. It begins by outlining the Humanization of Healthcare Framework ( Todres et al, 2009 ), which is a values-based context that can be used to underpin daily care. Generic applications for each of the dimensions of the framework are suggested. This framework is then used to contextualise my experience of receiving my diagnosis and the ensuing chemotherapy. Using examples from my personal narrative, I make some recommendations for 'small actions' that can contribute to more humanised and person-centred care...

Nurses are in a unique position to provide nutritional advice and information to women with breast cancer who are undergoing chemotherapy, supporting them with making decisions regarding nutrition and diet. This narrative review evaluated the research evidence relating to the nutritional challenges experienced during chemotherapy and the most effective approaches for supporting women in dietary choice. Weight gain was identified as a specific problem for women undergoing chemotherapy. The evidence indicated that information about nutrition and food preparation support may go some way in assisting women to overcome some of the nutrition-related difficulties experienced during chemotherapy treatment for breast cancer...

In this study, we investigated the excited-state proton transfer (ESPT) reaction for 3-cyano-7-azaindole (3CAI) in aqueous solution and in ice. 3CAI undergoes water catalyzed ESPT in the aqueous solution, giving normal (355 nm) and proton transfer tautomer (~472 nm) emission bands. Detailed temperature dependent studies showed that the values of activation free energy (△G≠) were similar between N-H and N-D isotope. Therefore, water catalyzed ESPT involves a stepwise mechanism incorporating solvation equilibrium (Keq) to form a 1:1 (molar ratio) water: 3CAI cyclic hydrogen bonded complex as an intermediate, followed by perhaps proton tunneling reaction...

Synthetic DNA is durable and can encode digital data with high density, making it an attractive medium for data storage. However, recovering stored data on a large-scale currently requires all the DNA in a pool to be sequenced, even if only a subset of the information needs to be extracted. Here, we encode and store 35 distinct files (over 200 MB of data), in more than 13 million DNA oligonucleotides, and show that we can recover each file individually and with no errors, using a random access approach. We design and validate a large library of primers that enable individual recovery of all files stored within the DNA...

INTRODUCTION: The literature shows an optimistic landscape for the effectiveness of games in medical education. Nevertheless, games are not considered mainstream material in medical teaching. Two research questions that arise are the following: What pedagogical strategies do developers use when creating games for medical education? And what is the quality of the evidence on the effectiveness of games? METHODS: A systematic review was made by a multi-disciplinary team of researchers following the Cochrane Collaboration Guidelines...

Dinis Oliveira, Ann I Larsson, Lena Granhag
Hull biofouling is a well-known problem for the shipping industry, leading to increased resistance and fuel consumption. Considering that the effects of hull form on resistance are known to be higher for a less slender hull, it is hypothesised in this paper that the effect of biofouling roughness on resistance is also dependent on the hull form. To test this hypothesis, previously reported full-scale numerical results on a containership are re-analysed. Form effects on roughness penalties, corresponding to KΔCT = 0...

BACKGROUND: Palliative care patients are often described as complex but evidence on complexity is limited. We need to understand complexity, including at individual patient-level, to define specialist palliative care, characterise palliative care populations and meaningfully compare interventions/outcomes. AIM: To explore palliative care stakeholders' views on what makes a patient more or less complex and insights on capturing complexity at patient-level. DESIGN: In-depth qualitative interviews, analysed using Framework analysis...
