Hypercompetition in biomedical research evaluation and its impact on young scientist careers
Recent years have seen tremendous changes in the modes of publication and dissemination of biomedical information, with the introduction of countless new publishers and publishing models, as well as alternative modes of research evaluation. In parallel, we are witnessing an unsustainable explosion in the amount of information generated by each individual scientist, at the same time as many countri
The Competing Mechanisms of Phosphate Monoester Dianion Hydrolysis
Despite the numerous experimental and theoretical studies on phosphate monoester hydrolysis, significant questions remain concerning the mechanistic details of these biologically critical reactions. In the present work we construct a linear free energy relationship for phosphate monoester hydrolysis to explore the effect of modulating leaving group pKa on the competition between solvent- and subst
Dynamics of the blood plasma proteome during hyperacute HIV-1 infection
The complex dynamics of protein expression in plasma during hyperacute HIV-1 infection and its relation to acute retroviral syndrome, viral control, and disease progression are largely unknown. Here, we quantify 1293 blood plasma proteins from 157 longitudinally linked plasma samples collected before, during, and after hyperacute HIV-1 infection of 54 participants from four sub-Saharan African cou
Promiscuity in the Enzymatic Catalysis of Phosphate and Sulfate Transfer
The enzymes that facilitate phosphate and sulfate hydrolysis are among the most proficient natural catalysts known to date. Interestingly, a large number of these enzymes are promiscuous catalysts that exhibit both phosphatase and sulfatase activities in the same active site and, on top of that, have also been demonstrated to efficiently catalyze the hydrolysis of other additional substrates with
Capturing the Role of Explicit Solvent in the Dimerization of RuV(bda) Water Oxidation Catalysts
A ground-breaking empirical valence bond study for a soluble transition-metal complex is presented. The full reaction of catalyst monomers approaching and reacting in the RuV oxidation state were studied. Analysis of the solvation shell in the reactant and along the reaction coordinate revealed that the oxo itself is hydrophobic, which adds a significant driving force to form the dimer. The effect
Associations between bioaerosols, lung function work-shift changes and inflammatory markers : A study of recycling workers
Objective We investigated associations between bioaerosol exposures and work-shift changes in lung function and inflammatory markers among recycling workers. Methods Inhalable dust was measured with personal samplers and analyzed for endotoxin, bacteria, and fungi (incubated at 25 °C and 37 °C) levels. Lung function (FEV1, FVC) was measured before and after work-shifts and serum concentrations of
Synchrotron-Based Phase-Contrast Micro-CT Combined With Histology to Decipher Differences Between Hereditary and Sporadic Pediatric Pulmonary Veno-Occlusive Disease
Pulmonary veno-occlusive disease (PVOD) is a lethal variant of pulmonary hypertension. The degree of pulmonary arterial involvement varies. Here, we compare two PVOD patients who were transplanted at 8 years of age, whereof one is a homozygous EIF2AK4 mutation carrier. Tissue was imaged with synchrotron-based micro-CT and the results were compared with clinical data and sectioned tissue was analyz
G-Quadruplexes in Nuclear Biomolecular Condensates
G-quadruplexes (G4s) have long been implicated in the regulation of chromatin packaging and gene expression. These processes require or are accelerated by the separation of related proteins into liquid condensates on DNA/RNA matrices. While cytoplasmic G4s are acknowledged scaffolds of potentially pathogenic condensates, the possible contribution of G4s to phase transitions in the nucleus has only
Bacterial growth and antimicrobial resistance in urinary Escherichia coli isolates among men with lower UTI in Swedish primary healthcare: retrospective data over a 4 year period
Background: Escherichia coli, the most common bacterium causing urinary tract infections (UTIs), is increasinglyreported as resistant to multiple antibiotics. Swedish surveillance data from hospital and primary health care(PHC) report a 17%–19% prevalence of resistance to ciprofloxacin in E. coli from urine cultures in men over20 years of age. Surveillance data may include nosocomial infections.

Ungdomsfängelse: En lösning eller ett nytt problem?
Ungdomskriminaliteten har särskilt under de senare åren varit ett ämne som ständigt uppkommit i den kriminalpolitiska debatten. Regeringen gav under 2021 en särskild utredare i uppdrag att genomföra en översyn av regleringen om frihetsberövande påföljder för barn och att utifrån denna presentera förslag på lämpliga förändringar. Detta resulterade i SOU 2023:44 som presenterades i augusti 2023. I dJuvenile delinquency has in recent years been a topic that has constantly arisen in the justice policy debate and in 2021 the government appointed an inquiry chair to carry out a review of the regulations on custodial penalties for children, and on the basis of this investigation present proposals for suitable revisions. This resulted in SOU 2023:44 which was presented in August of 2023. In this,

Lönetransparensdirektivet och dess påverkan på arbetsgivare: Utmaningar och möjligheter - En analys av hur det nya lönetransparensdirektivet förändrar arbetsgivares förutsättningar i Sverige
Lönediskriminering med kön som grund är en problematik som alltid har präglat arbetsmiljön och som har varit en utmaning att motverka. Sedan 1960-talet har det gjorts försök att bekämpa denna genom konventioner, lagar och andra rättsliga insatser. År 2023 antogs EU-direktivet (2023/970) “om stärkt tillämpning av principen om lika lön för kvinnor och män för lika eller likvärdigt arbete genom insynGender-based pay discrimination is a problem that has always characterized the work environment and has been a challenge to combat. Since the 1960s, attempts have been made to combat it through conventions, laws and other legal measures. In 2023, the European Union adopted the Directive (2023/970) “on the strengthening of the application of the principle of equal pay for male and female workers fo
Choroid plexus extracellular vesicle transport of blood-borne insulin-like growth factor 1 to the hippocampus of the immature brain
Reduced serum level of insulin-like growth factor 1 (IGF-1), a major regulator of perinatal development, in extremely preterm infants has been shown to be associated with neurodevelopmental impairment. To clarify the mechanism of IGF-1 transport at the blood–cerebrospinal fluid (CSF) barrier of the immature brain, we combined studies of in vivo preterm piglet and rabbit models with an in vitro tra
