Unique molecular identifiers (UMI) can be used in forensic STR sequencing to reduce the level of analytical artifacts. Here, we perform an interlaboratory study across five independent sites where the previously developed UMI-based SiMSen-Seq STR assay is applied at each laboratory to both single-source and mixed samples. The assay showed consistent results between laboratories and more than 90% o
Proteins are useful chiral selectors. In order to understand the recognition mechanism and chiral discrimination, the binding of the (R)- and (S)-enantiomers of a series of designed amino alcohol inhibitors based on propranolol to cellobiohydrolase Cel7A (Trichoderma reesei) has been studied more closely. X-ray crystal structures were determined of the protein complex with the (R)- and (S)-enantio
The diffusion of macromolecules, nanoparticles, viruses, and bacteria is essential for targeting hosts or cellular destinations. While these entities can bind to receptors and ligands on host surfaces, the impact of multiple binding sites—referred to as multivalency—on diffusion along strands or surfaces is poorly understood. Through numerical simulations, we have discovered a significant accelera
Understanding of carbon nanomaterials oxidation is useful in many different applications, e.g., for soot emission abatement, or in defect engineering aiming to improve material properties. In this work, the oxidative behavior of three substantially different qualities of carbon black, multiwall carbon-nanotubes, and few-layer graphene, was studied using a combination of macroscale quantification (
OBJECTIVES: Early diagnosis of critical congenital heart defects (CCHD) improves survival. We evaluated the relative contributions of prenatal ultrasound, neonatal pulse oximetry screening (POS), and neonatal physical examination (NPE) to the early detection (before discharge) of CCHD in the context of increasing prenatal detection, and POS being a national standard since 2013. METHODS: Retrospect
The main protease Mpro, nsp5, of SARS-CoV-2 (SCoV2) is one of its most attractive drug targets. Here, we report primary screening data using nuclear magnetic resonance spectroscopy (NMR) of four different libraries and detailed follow-up synthesis on the promising uracil-containing fragment Z604 derived from these libraries. Z604 shows time-dependent binding. Its inhibitory effect is sensitive to
OBJECTIVES: Many universities offer faculty development to support teachers in developing and improving clinical education in the health professions. Although research shows outcomes on individual levels after faculty development, little is known about its contribution to change within the organisation. To advance current faculty development and ensure that it can support wider educational change
This study aims to broaden our historical knowledge about ideas of rationalism and monocultures in forestry science and rational forest management. Empirically, it focuses on the writings of Swedish forestry scientist Henrik Hesselman, active in the early twentieth century. The texts were analyzed using the method of historical contextualization. The study indicates that monocultures historically
Translation-targeting toxic small alarmone synthetases (toxSAS) are effectors of bacterial toxin-antitoxin systems that pyrophosphorylate the 3'-CCA end of transfer RNA (tRNA) to prevent aminoacylation. toxSAS are implicated in antiphage immunity: Phage detection triggers the toxSAS activity to shut down viral production. We show that the toxSAS FaRel2 inspects the tRNA acceptor stem to specifical
Background Patients with acute coronary syndrome (ACS) are often admitted to monitored wards due to the risk of complications. Several risk prediction scores exist, but their use in the emergency department (ED) is limited. We aimed to compare the ability of existing risk scores with a new logistic regression model in predicting complications in ACS patients. Methods This was a secondary analysis
Many animals, such as birds and bats, are capable of migrating over vast distances to specific destinations. Remarkably, even insects such as the North American Monarch butterfly and the Australian Bogong moth undertake similarly long-distance migrations to specific sites. Here, we provide an overview of our current understanding of the migration of these insects and outline the sensory cues and n
We assessed if fasting plasma insulin levels in pregnant women with obesity are associated with newborns’ abdominal fat deposition (dual-energy X-ray absorptiometry) and with cord blood DNA methylation (450k array) in 232 mother–child pairs from the Treatment of Obese Pregnant women (TOP) study. Fasting maternal insulin at 18-20gw was associated with abdominal/total fat mass ratio in newborns inde
Angiogenesis potentially underlies the pathway between excess adiposity and prostate carcinogenesis. This study examined the association between lifetime body shape trajectories and prostate cancer angiogenesis. 521 prostate cancer patients who underwent prostatectomy or transurethral resection between 1986 and 2000 were enrolled from the Health Professionals Follow-up Study. Cancers were immunost
Purpose: Chronic rhinosinusitis (CRS) is related to asthma and chronic obstructive pulmonary disease (COPD). However, combined data on CRS, pulmonary function, lower airway symptoms, and cigarette smoking from the general population are lacking. The current study investigates the relationships between CRS and chronic airflow limitation (CAL), lower airway symptoms and COPD in a middle-aged populat
Luminescent properties of KTb(MoO4)2 and K5Tb(MoO4)4 crystals, possessing the same elemental composition but different crystal structures, were studied. The structural arrangement of Tb3+ ions, ordered in KTb(MoO4)2 and disordered in K5Tb(MoO4)4, determines their luminescence properties. Partial lattice disorder of K5Tb(MoO4)4 results in broadened bands of Tb3+ emission and excitation spectra, but
Galectins are a family of carbohydrate-recognising proteins involved in regulation of cell adhesion and cell signaling, leading to roles in e.g. cancer progression, fibrosis, and ulcerative colitis. Glycomimetic galectin inhibitors based on different molecular scaffolds are known and have demonstrated effects from cell experiments to the clinic. Presented here is the synthesis and evaluation of 3-
Steric clashes pose a challenge when exploring dense protein systems using conventional explicit-chain methods. A minimal example is a single lattice protein confined on a minimal grid, with no free sites. Finding its minimum energy is a hard optimization problem, with similarities to scheduling problems. It can be recast as a quadratic unconstrained binary optimization (QUBO) problem amenable to
For navigation, animals use a robust internal compass. Compass navigation is crucial for long-distance migrating animals like monarch butterflies, which use the sun to navigate over 4,000 km to their overwintering sites every fall. Sun-compass neurons of the central complex have only been recorded in immobile butterflies, and experimental evidence for encoding the animal's heading in these neurons
