Mononuclear iron(iv)-oxo, iron(iv)-imido and iron(iv)-nitrido complexes are common catalytic cycle intermediates in enzymes, where the metal is typically linked to the protein through cysteinate or histidine sidechains. Enzymatic high-valent iron(iv)-imido and -nitrido intermediates have never been trapped and characterized; hence, there is uncertainty regarding their structure and function. Using
The birth prevalence of cleft lip and/or palate (CL/P) varies globally, and regional differences have previously been observed within Sweden. Updated data on CL/P birth prevalence is needed and has been requested nationally and internationally. This study investigated regional differences and temporal trends in the birth prevalences of CL/P and specific cleft subtypes across Sweden’s six health ca
Near infrared (NIR) fluorescence imaging has received significant attention. However, it remains challenging to develop NIR emitters with a high brightness. Herein, we report a supramolecular approach to formulate NIR fluorescent molecular nanoparticles from cationic NIR fluorophores and cyanostar receptors using their charge-by-charge packing in small-molecule ionic isolation lattices (SMILES). F
Knee osteoarthritis is a highly prevalent whole-joint disease that is associated with substantial morbidity. If step changes are to be made in the management of knee osteoarthritis, novel patient stratification approaches are needed to identify the most effective treatment for individual patients. Numerous methods for stratifying patients with knee osteoarthritis can be employed; clinical presenta
Biogenic ice-nucleating particles (INPs) can significantly impact mixed-phase clouds by enhancing precipitation and reducing albedo. As Arctic sea ice diminishes, the exposure of open ocean may increase aerosolization rates of marine bioaerosols and INPs. We investigated INP concentrations and microbial communities in ambient marine air, sea bulk water (SBW), and sea surface microlayer (SML) along
BackgroundPatients with advanced ovarian cancer (AOC) who undergo primary and interval debulking surgery are often anemic at diagnosis, with iron deficiency being the most common cause. The aim was to investigate whether preoperative anemia and iron deficiency impact short-term recovery.MethodsThis retrospective cohort study included 262 patients with AOC who underwent surgery at Skane University
The transition to smart, wearable, and flexible optoelectronic devices that communicate with each other and perform neuromorphic computing at the edge, is a major goal in next-generation optoelectronics. These devices are expected to carry out their regular tasks while being supported by energy-efficient, in-memory computations. In this study, a lateral flexible device based on cesium lead tribrom
Epitaxially grown nanowires have shown promise for photovoltaic applications due to their nanophotonic properties. Moreover, the mechanical properties of nanowires can reduce crystallographic defect formation at interfaces to help enable new material combinations for photovoltaics. One material that stands to benefit from the nanowire morphology is zinc phosphide (Zn3P2), which, despite promising
Background: Medial plica is a structure with limited understanding of its pathology, but it may be related to the development of medial knee osteoarthritis (OA). We examined the association between medial plica and medial meniscus extrusion (MME), progression of MME, and the risk of early-stage knee OA development in middle-aged persons. Methods: A total of 340 subjects with tibiofemoral Kellgren–
Aims Aortic valve calcification (AVC) is an underlying pathophysiological mechanism for aortic stenosis that is common in the elderly, but less is known in younger individuals. The aim was to study the prevalence and associated characteristics of AVC in a middle-aged general population. Methods and results Data were obtained from the Swedish CArdioPulmonary bioImage Study (SCAPIS) comprising 30 15
Rare earth elements (lanthanides) are critical materials for many applications, particularly those involved in new energy. Extracting these elements economically from low-concentration sources may be challenging. This study investigates the interaction of Ce and Gd with microalgae that have been triggered to form phosphate-rich granules. Lanthanides usually occur in nature as phosphates, and there
When exposed to high levels of phosphate after experiencing phosphate deficiency, microalgae can synthesize granules rich in intracellular phosphate. The understanding of the mechanism of production and nature of these granules remains incomplete. Here we studied phosphate distribution and chemistry in Chlamydomonas reinhardtii and Desmodesmus armatus using scanning transmission X-ray microscopy (
Early kidney function decline may be associated with reduced filtration of middle-sized molecules, currently defined as selective glomerular hypofiltration syndrome (SGHS), and driven by the accumulation of atherosclerosis-promoting proteins. We aimed to investigate whether SGHS and other markers of kidney function are associated with subclinical atherosclerosis as evaluated by intima-media thickn
Background: Women who have undergone cervical conization may still experience subsequent pregnancies and delivery. However, it remains unknown whether pregnancy, associated with immune tolerance, might increase the risk of subsequent cervical lesions. This study aims to address this knowledge gap by utilizing the nationwide Swedish registers. Methods: A total of 60,895 women diagnosed with cervica
Background: Low-cost particulate matter sensors have enabled new opportunities for exposure monitoring but require evaluation before application in epidemiological studies. This study assessed the performance of the SPS30 sensor integrated into the ARMIE portable monitoring sensor-node under controlled laboratory conditions. Methods: Sensors were co-located with two comparison instruments—the opti
Background: Human immunodeficiency virus type 1 (HIV-1) is one of the fastest-evolving human pathogens. Understanding HIV-1 transmission, within-host adaptation, and evolutionary dynamics is pivotal for development of interventions and vaccines. HIV-1 infection is generally caused by a single transmitted founder virus (TFV), and TFV sequences are typically obtained using single genome amplificatio
The process that generates the different types of highly differentiated cells in the immune system from hematopoietic stem cells involves not only the acquisition of lineage-specific features, but also the permanent repression of alternative developmental programs and the preservation of lineage identity. The well-charted developmental trajectory of early B-cell development, in combination with ab
Cystitis is a bacterial infection of the bladder that occurs in about half of women at least once in their lifetime. Antibiotics such as nitrofurantoin are used to treat cystitis, but antibiotic resistance is a concern, especially for recurrent infections. Here we report an open-label, randomized, single-centre, phase 2 study to analyse the acute and long-term safety and efficacy of the IL-1 recep
Objective: Prior to in vitro fertilization (IVF), physicians can choose either recombinant or urine-derived follicle-stimulating hormone (FSH) for ovarian stimulation. The common polymorphism N680S (rs6166) in the follicle-stimulating hormone receptor (FSHR) has been linked to individual variability in ovarian response to FSH stimulation and IVF outcomes, including live birth rates, highlighting i
Background: Late effects of polio (LEoP) are defined as new symptoms, for example, muscle weakness, fatigue, and pain, occurring many years after an acute polio infection. These impairments can lead to difficulties performing everyday activities (ie, activity limitations) that can reduce a person's ability to take part in society (ie, perceived participation restrictions). Yet, no study has explor
