Putative reaction mechanism of nitrogenase after dissociation of a sulfide ligand

We have investigated the implications of the recent crystallographic findings that the m2-bridging S2B sulfide ligand may reversibly dissociate from the active-site FeMo cluster of nitrogenase. We show with combined quantum mechanical and molecular mechanical (QM/MM) calculations that once S2B has dis- sociated, N2 may bind in that position and can be protonated to two NH3 groups by thermodynamica

Risk of invasive prostate cancer and prostate cancer death in relatives of patients with prostatic borderline or in situ neoplasia : A nationwide cohort study

BACKGROUND: The question of whether having a family history of prostatic borderline or in situ neoplasia (PBISN) is associated with an increased risk of invasive prostate cancer (PCa) or death from PCa remains unanswered. The objective of the current study was to provide an evidence-based risk estimation for the relatives of patients with PBISN.METHODS: Nationwide Swedish family cancer data sets w

Perioperative management in order to minimise postoperative delirium and postoperative cognitive dysfunction : Results from a Swedish web-based survey

Cognitive side-effects such as emergence agitation (EA), postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are not infrequently complicating the postoperative care especially in elderly and fragile patients.The aim of the present survey was to gain insight regarding concern and interest in prevention and treatment strategies for postoperative delirium and dysfunction, and

Evaluation of the Postoperative Quality of Recovery Scale test and re-test in Swedish among healthy volunteers

Introduction Patient outcome measures are required to assess the quality of healthcare. Tools for a patients' self-assessment of quality of recovery, during perioperative care, have been developed during the last decade. The Postoperative Quality of Recovery Scale (PostopQRS) questionnaire is one of the most well-accepted and validated tools available. Here we assess the PostopORS questionnaire in

Mal de débarquement syndrome : Diagnostic criteria consensus document of the classification committee of the bárány society

We present diagnostic criteria for mal de débarquement syndrome (MdDS) for inclusion into the International Classification of Vestibular Disorders. The criteria include the following: 1] Non-spinning vertigo characterized by an oscillatory sensation ('rocking,' 'bobbing,' or 'swaying,') present continuously or for most of the day; 2] Onset occurs within 48 hours after the end of exposure to passiv

En farlig tid för män?

Gabriella Nilsson är docent och lektor vid institutionen för kulturvetenskaper på Lunds universitet. Här berättar hon om varför vi, till skillnad från vad bland annat personer som president Donald Trump och författaren Horace Engdahl sagt, inte lever i "en farlig tid för män". Inspelat den 8 mars 2019 på Lunds universitet.

Överlappningen mellan dataskydd och marknadsrätt : Dataskyddsförordningens tillämpning på marknadsföring och marknadsrättens tillämpning på kommersiell personuppgiftsbehandling

Digitaliseringen gör det möjligt för näringsidkare att utveckla nya affärsmodeller, upptäcka nya marknader och att rationalisera sina verksamheter.En viktig aspekt i denna utveckling utgör att samla in, behandla och på olika sätt utnyttja personuppgifter av såväl befintliga som presumtiva kunder. Av den anledningen existerar ett naturligt samband mellan personuppgifter och näringsverksamhet och fr

Mass spectrometry-based analysis of formalin-fixed, paraffin-embedded distal cholangiocarcinoma identifies stromal thrombospondin-2 as a potential prognostic marker

Background: Distal cholangiocarcinoma is an aggressive malignancy with a dismal prognosis. Diagnostic and prognostic biomarkers for distal cholangiocarcinoma are lacking. The aim of the present study was to identify differentially expressed proteins between distal cholangiocarcinoma and normal bile duct samples. Methods: A workflow utilizing discovery mass spectrometry and verification by parallel

The Ubiquitin Proteasome System in Neuromuscular Disorders : Moving Beyond Movement

Neuromuscular disorders (NMDs) affect 1 in 3000 people worldwide. There are more than 150 different types of NMDs, where the common feature is the loss of muscle strength. These disorders are classified according to their neuroanatomical location, as motor neuron diseases, peripheral nerve diseases, neuromuscular junction diseases, and muscle diseases. Over the years, numerous studies have pointed

Upper extremity nerve block : How can benefit, duration, and safety be improved? An update [version 1; referees: 3 approved]

Upper extremity blocks are useful as both sole anaesthesia and/or a supplement to general anaesthesia and they further provide effective postoperative analgesia, reducing the need for opioid analgesics. There is without doubt a renewed interest among anaesthesiologists in the interscalene, supraclavicular, infraclavicular, and axillary plexus blocks with the increasing use of ultrasound guidance.

Coronavirus and the Challenge of World Politics

The abrupt emergence of COVID-19, has ushered in health crises around the world and has affected global security. This pandemic shows that the relationship between security affairs and global health is becoming one of the more complicated topics in world politics. The states’ unilateral and individualized response to this transnational threat marks a shift in international relations away from glob

ASSERT - Kontroll av markstabilisering med resistivitetstomografi

Ground improvement with lime-cement pillars is becoming increasingly common in the Nordic countries for exploitation of areas with poor stability. However, there is a need for non-destructive methods for volumetric quality control of the ground improvement. The quality control can be divided into two steps where the first include quality control at the installation process with monitoring of produ

New Evidence on the Importance of Instruction Time for Student Achievement on International Assessments

We revisit and substantially extend the evidence on the importance of instruction time for student achievement on international assessments. We first successfully replicate the estimate of a positive effect of weekly instruction time in the seminal paper by Lavy (Economic Journal, 125, F397-F424) in a narrow sense. We then extend the analysis to data from other international student assessments an
