Irreversible enzyme inhibitors often utilize the reaction of a protein cysteine residue with an appropriately positioned electrophile (an acrylamide for example) in the ligand template. Cysteine residues are not always available for site-specific protein labeling and therefore new approaches are needed to expand the toolkit of appropriate electrophiles that target alternative amino acids. We have previously described the rational targeting of tyrosine residues in the active site of a protein (the mRNA decapping scavenger enzyme, DcpS) using inhibitors armed with sulfonyl fluoride electrophiles that additionally enabled the subsequent development of clickable probe technology to measure drug-target occupancy in live cells...

Rapid diffusion, low cost and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, communication and interventions in asthma. There is little information in Latin America about usage frequency of ICTs in asthmatic patients. The analysis undertaken consisted of an observational, cross-sectional study that aimed to identify the frequency and type of ICTs most often used by asthmatics. The Spanish version of the Michigan questionnaire was employed in five Latin American countries...

Weichao Huang, Fayza Daboussi
Diatoms have attracted considerable attention due to their success in diverse environmental conditions, which probably is a consequence of their complex origins. Studies of their metabolism will provide insight into their adaptation capacity and are a prerequisite for metabolic engineering. Several years of investigation have led to the development of the genome engineering tools required for such studies, and a profusion of appropriate tools is now available for exploring and exploiting the metabolism of these organisms...

In 2011, an Institute of Medicine report on health information technology (IT) and patient safety highlighted that building health-IT for safer use is a shared responsibility between key stakeholders including: "vendors, care providers, healthcare organizations, health-IT departments, and public and private agencies". Use of electronic health records (EHRs) involves all these stakeholders, but they often have conflicting priorities and requirements. Since 2011, the concept of shared responsibility has gained little traction and EHR developers and users continue to attribute the substantial, long list of problems to each other...

This case study considers the clinical ethics issues of medical appropriateness and quality of life for patients who are critically ill. The case involves a terminally ill cancer patient with a profoundly diminished quality of life and an extremely poor prognosis; his spouse desires to bring him home, where she will arrange to keep him alive for as long as possible via life-sustaining interventions. The analysis engages with the complicated notion of medical appropriateness, both in general and as it pertains to life-sustaining interventions in a critical care setting, and considers the ethical implications of the various ways in which one might understand this concept...

BACKGROUND: Enteropathogen detection traditionally relies on diarrhoeal stool samples, but these are inconvenient to collect if they are not immediately available, leading to suboptimum return rates of samples and delayed or missed diagnostic opportunities. We sought to compare the enteropathogen yields of rectal swabs and stool specimens in children with diarrhoea or vomiting, or both. METHODS: The Alberta Provincial Pediatric EnTeric Infection TEam (APPETITE) did a study in three outpatient cohorts in Calgary and Edmonton (AB, Canada)-children enrolled in the Pediatric Emergency Research Canada emergency departments, children receiving routine vaccinations at a Calgary health clinic, and symptomatic children who met criteria for treatment at home...

A review of the Health Information and Quality Authority's (HIQA) assessment of breast cancer surveillance cancer criticized how the results were presented and interpreted. The health technology assessment (HTA) investigated surveillance options for women aged less than 50 years who were at elevated risk of breast cancer. Surveillance strategies using digital mammography, magnetic resonance imaging, or a combination of the two modalities were modeled on the basis of diagnostic test accuracy. The HTA faced a number of issues, including the use of diagnostic test accuracy as a surrogate for long-term outcomes; modeling interventions that were not considered acceptable to clinicians; and extrapolating for screening intervals and age ranges not directly supported by available evidence...

Honghao Bi, Bing Yang
Engineered, site-specific nucleases induce genomic double-strand DNA breaks and break repair processes enable genome editing in a plethora of eukaryotic genomes. TALENs (transcription activator-like effector nucleases) and CRISPR/Cas (clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins) are potent biotechnological tools used for genome editing. In rice, species-tailored editing tools have proven to be efficient and easy to use. Both tools are capable of generating DNA double-strand breaks (DSBs) in vivo and such breaks can be repaired either by error-prone NHEJ (nonhomologous end joining) that leads to nucleotide insertions or deletions or by HDR (homology-directed repair) if an appropriate exogenous DNA template is provided...

INTRODUCTION: Chosen European foreign policy vector for Ukraine establishes its obligation to enforce the process of adaptation of the EU law regulations in the internal legal policy. The approximation of Ukrainian law to the European Union (EU) "acquis communautaire" is not only the instrument for deepening our economic cooperation with the European Union, but also the important measure to enhance further development of Ukraine in general. National legislation, which regulate advertising and promotion of medical devices (MD), is not an exception...

Robotic milking reduces labor demands on dairy farms of all sizes and offers a more flexible lifestyle for farm families milking up to 250 cows. Because milking is voluntary, barn layouts that encourage low-stress access by providing adequate open space near the milking stations and escape routes for waiting cows improve milking frequency and reduce fetching. Because lame cows attend less often, preventing lameness with comfortable stalls, clean alley floors, and effective foot bathing warrants special emphasis in robotic dairies...

The classic development of vaccines is lengthy, tedious, and may not necessarily be successful as demonstrated by the case of HIV. This is especially a problem for emerging pathogens that are newly introduced into the human population and carry the inherent risk of pandemic spread in a naïve population. For such situations, a considerable number of different platform technologies are under development. These are also under development for pathogens, where directly derived vaccines are regarded as too complicated or even dangerous due to the induction of inefficient or unwanted immune responses causing considerable side-effects as for dengue virus...

Synthetic lethality occurs when co-occurrence of two genetic events is unfavorable for the survival of the cell or organism. The conventional approach of high throughput screening of synthetic lethal targets using chemical compounds has been replaced by RNAi technology. CRISPR/Cas9, an RNA guided endonuclease system is the most recent technology for this work. Here, we have discussed the major considerations involved in designing a CRISPR/Cas9 based screening experiment for identification of synthetic lethal targets...

Inappropriate waste management and poor resource efficiency are two of the biggest problems which European Union is trying to solve through Landfill Directive, Waste Framework Directive and Circular Economy Package by increasing recycling and reuse and reducing waste disposal. In order to meet set goals, new European Union member states must quickly change national legislature and implement appropriate solutions. In the circumstances of strong EU resource and energy dependence, decision makers need to analyse which of the considered waste management systems leads to higher overall benefits ie...

BACKGROUND: Prosthodontics involves replacing lost dentofacial structures using artificial substitutes. Due to availability of many materials and techniques, clinician's clinical decision-making regarding appropriate selection of prosthesis requires critical thinking abilities and is demanding. Especially during graduate training years, learners do not receive the exposure to a variety of cases, thus their clinical reasoning skills are not developed optimally. Therefore, using the trend of incorporating technology in education, we developed a mobile learning app for this purpose...
