ppmFixer: a mass error adjustment for pGlyco3.0 to correct near-isobaric mismatches.

Modern glycoproteomics experiments require the use of search engines due to the generation of countless spectra. While these tools are valuable, manual validation of search engine results is often required for detailed analysis of glycopeptides as false-discovery rates are often not reliable for glycopeptide data. Near-isobaric mismatches are a common source of misidentifications for the popular glycopeptide-focused search engine pGlyco3.

Sequential in vitro enzymatic N-glycoprotein modification reveals site-specific rates of glycoenzyme processing.

N-glycosylation is an essential eukaryotic posttranslational modification that affects various glycoprotein properties, including folding, solubility, protein-protein interactions, and half-life. N-glycans are processed in the secretory pathway to form varied ensembles of structures, and diversity at a single site on a glycoprotein is termed 'microheterogeneity'. To understand the factors that influence glycan microheterogeneity, we hypothesized that local steric and electrostatic factors surrounding each site influence glycan availability for enzymatic modification.

Regulating the Regulators: Mechanisms of Substrate Selection of the O-GlcNAc Cycling Enzymes OGT and OGA.

Thousands of nuclear and cytosolic proteins are modified with a single β-N-acetylglucosamine on serine and threonine residues in mammals, a modification termed O-GlcNAc. This modification is essential for normal development and plays important roles in virtually all intracellular processes. Additionally, O-GlcNAc is involved in many disease states, including cancer, diabetes, and X-linked intellectual disability.

Comparison between epidural and opioid analgesia for infants undergoing major abdominal surgery.

Background: Epidural analgesia is considered optimal for postoperative pain management after major abdominal surgery. The potential to decrease anesthetic and opioid exposure is particularly desirable for infants, given their vulnerability to respiratory depression and concern for anesthetic neurotoxicity. We reviewed our experience with infants undergoing major abdominal surgery to determine if epidural catheter use decreased anesthetic and opioid exposure and improved postoperative analgesia.

Explainable machine-learning predictions for the prevention of hypoxaemia during surgery.

Although anaesthesiologists strive to avoid hypoxemia during surgery, reliably predicting future intraoperative hypoxemia is not currently possible. Here, we report the development and testing of a machine-learning-based system that, in real time during general anaesthesia, predicts the risk of hypoxemia and provides explanations of the risk factors. The system, which was trained on minute-by-minute data from the electronic medical records of over fifty thousand surgeries, improved the performance of anaesthesiologists when providing interpretable hypoxemia risks and contributing factors.

The Use of Opioids for Treatment of Pediatric Neuropathic Pain: A Literature Review.

Pediatric neuropathic pain is caused by a spectrum of disorders that are generally challenging to treat. Many of the underlying altered neurological processes are being elucidated through mechanistic studies. Few randomized control trials have evaluated the use of opioids for the treatment of adult neuropathic pain conditions, and there have been none in pediatric populations.

Complications in Pediatric Regional Anesthesia: An Analysis of More than 100,000 Blocks from the Pediatric Regional Anesthesia Network.

What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complications in pediatric regional anesthesia are rare, so a large sample size is necessary to quantify risk. The Pediatric Regional Anesthesia Network contains data on more than 100,000 blocks administered at more than 20 children's hospitals. This study analyzed the risk of major complications associated with regional anesthesia in children.

Demonstration of the usefulness of a theoretical framework for humanising care with reference to a residential aged care service in Australia.

Aims And Objectives: To demonstrate the usefulness of a theoretical framework for humanising care of dementia patients.

Background: The term humanisation of care has been increasingly used to describe an approach to health care that is informed by core dimensions of what it means to be human. Recent developments in dementia care highlight the importance of maintaining personhood in people with dementia.

The applicability of a recovery approach to nursing people with dementia.

Objectives: Recent developments in nursing to people with mental health conditions of working age have been underpinned by the recovery approach. This paper critically reviews the idea of recovery in relationship to people with dementia and examines its applicability to dementia care nursing.

Design: The paper critically reviews literature relating to the use recovery approach and the people with dementia, particularly their nursing care.

A whole-systems approach for dementia care.

The nursing care of people with dementia is carried out mainly by general and mental health nurses, and takes place in a wide variety of settings such as accident and emergency units, orthopaedic wards, people's homes, long- stay wards and day hospitals ( care Services Improvement Partnership (CSIP) 2005 ). My own experience of nursing people with dementia is as a mental health nurse, but my mother developed dementia and this has enabled me to see dementia care nursing from a different angle.

Chemical composition of some components of the arrestment pheromone of the black-legged tick, Ixodes scapularis (Acari: Ixodidae) and their use in tick control.

Chemical analysis (high-performance liquid chromatography) and bioassay demonstrated the presence of compounds that seem to be components of the Ixodes scapularis arrestment pheromone. Only two purines, guanine and xanthine, were found in acidified saline extracts made from cast skins after molting of fed nymphs, fed larvae, and fecal/excretory exudates deposited by unfed adults on substrates in their environment. The ratio of guanine to xanthine was 10.

Age and opportunity?

Recent discussions about raising the age at which people qualify for an old age pension are pertinent to the work of nurses supporting older people. They also raise questions about the possibility of other anti-discrimination changes within health and social care provision. Retirement age looks set to become more flexible and so age-based services may need to reflect this variation.
