Optical demonstration of crystallography and reciprocal space using laser diffraction from Au microdisc arrays

Crystallography is an invaluable tool in materials science, solid state physics and protein science. Understanding crystallography requires grasping the powerful but abstract concept of reciprocal space. Here a simple but insightful experiment using a laser pointer and Au microdisc arrays to explore and illustrate Bragg diffraction and reciprocal space is demonstrated. The Au microdisc arrays were

The metamorphic and magmatic record of collisional orogens

The Cenozoic Himalaya-Tibet orogen is generally regarded as the archetypal continental collision zone and is often used as an analogue for interpreting ancient orogenic events. However, given the wide diversity observed in present-day collisional mountain belts, the extent to which such inferences can be made remains debated. In this Review, we compare the metamorphic and magmatic record of the Hi

DutaFabs are engineered therapeutic Fab fragments that can bind two targets simultaneously

We report the development of a platform of dual targeting Fab (DutaFab) molecules, which comprise two spatially separated and independent binding sites within the human antibody CDR loops: the so-called H-side paratope encompassing HCDR1, HCDR3 and LCDR2, and the L-side paratope encompassing LCDR1, LCDR3 and HCDR2. Both paratopes can be independently selected and combined into the desired bispecifWe report the development of a platform of dual targeting Fab (DutaFab) molecules, which comprise two spatially separated and independent binding sites within the human antibody CDR loops: the so-called H-side paratope encompassing HCDR1, HCDR3 and LCDR2, and the L-side paratope encompassing LCDR1, LCDR3 and HCDR2.

FLASH irradiation induces lower levels of DNA damage ex vivo, an effect modulated by oxygen tension, dose, and dose rate

OBJECTIVE: FLASH irradiation reportedly produces less normal tissue toxicity, while maintaining tumour response. To investigate oxygen's role in the 'FLASH effect', we assessed DNA damage levels following irradiation at different oxygen tensions, doses and dose rates.METHODS: Samples of whole blood were irradiated (20 Gy) at various oxygen tensions (0.25-21%) with 6 MeV electrons at dose rates of

Brain injury markers in blood associate with generalised oedema on computed tomography after cardiac arrest

Introduction. According to the 2021 ERC/ESICM guideline recommen-dations, elevated neuron-specific enolase [NSE] levels as well as diffuseand extensive anoxic damage on neuroimaging are predictors of poorneurological outcome after cardiac arrest.(1) We previously describedthat NSE is elevated in patients with generalised oedema on com-puted tomography [CT]. (2).Objectives. In this study, we aim to

Did it pay to be a pioneer? Wealth accumulation in a newly settled frontier society

While wealth-holding patterns in rural areas have been well studied, the link between initial conditions, prospects for wealth accumulation, and the persistence of inequality at an agricultural frontier is less clear. On the one hand, the frontier is thought to have had a levelling effect, with the availability of cheap land acting as an equalizer. On the other hand, land rents, accumulated during

Managing Memory in Post-Soviet Ukraine : From "Scientific Marxism-Leninism" to the Ukrainian Institute of National Memory, 1991-2019

The post-Soviet Ukrainian polity has invested considerableresources into forming and managing what it refers to as “nationalmemory” (natsional’na pam’iat’). The Soviet forms and roots of thismemory production are easily discernible, though the ideologicalcontent has changed. Two presidents stood out as particularly activein the field of memory management: Viktor Yushchenko (2005–2010)and Petro Por

Air pollution and increased number of psychiatric emergency room visits : A case-crossover study for identifying susceptible groups

Background: Ambient particulate matter is a leading risk factor for disease globally. Particulate matter 10 (PM10) and particulate matter 2.5 (PM2.5) are derived from different sources, including operating motor vehicles as well as from industrial activities. In this study we investigate the association between increased concentrations of PM and total daily visits to the psychiatric emergency unit

The use of asymmetric time constraints in 4-D ERT inversion

Time-lapse resistivity surveys are commonly used to monitor temporal changes in the subsurface. In certain cases, it is known from other information that the resistivity will only decrease or increase with time. The 4-D resistivity smoothness-constrained inversion method reduces artifacts due to noise by including a temporal roughness filter constraint that ensures the temporal changes vary in a s

Insights into plastic deformation and binder lamella orientation in hardmetal turning inserts

This paper studies the underlying mechanisms to binder phase lamella formation (in WC/WC grain boundaries) in hardmetal inserts used in face turning. A distribution of lamellae orientations has been quantified for used turning inserts as well as pristine inserts and coupled to the direction of the applied stress, calculated by FEM. Furthermore, more detailed FEM calculations on the micro scale hav

Microbial formation and stabilisation of soil organic carbon is regulated by carbon substrate identity and mineral composition

The view that soil organic C (SOC) is formed mainly from non-metabolised and recalcitrant organic residues is being challenged by an emerging view that metabolic by-products form more stable associations with soil minerals. However, the effects of C substrate identity and soil mineral composition (and interactions) on microbial physiology and SOC formation are still not well understood. We added c

Regulatory networks and 5' partner usage of miRNA host gene fusions in breast cancer

Genomic rearrangements in cancer cells can create gene fusions where the juxtaposition of two different genes leads to the production of chimeric proteins or altered gene expression through promoter-swapping. We have previously shown that fusion transcripts involving microRNA (miRNA) host genes contribute to deregulation of miRNA expression regardless of the protein-coding potential of these trans

ABC om Syra–bastolkning på akuten

The analysis of acid-base disturbances contributes to the diagnostic work-up of critically ill patients. Most emergency departments are equipped with blood gas point-of-care analyzers that quantify within minutes pH, pCO2, standard bicarbonate, standard base excess, sodium and chloride levels. This article provides a pragmatic stepwise approach to the analysis of acid-base disturbances in the emer

Monitoring the interactions between alpha-synuclein and Tau in vitro and in vivo using bimolecular fluorescence complementation

Parkinson’s disease (PD) and Alzheimer’s disease (AD) are characterized by pathological accumulation and aggregation of different amyloidogenic proteins, α-synuclein (aSyn) in PD, and amyloid-β (Aβ) and Tau in AD. Strikingly, few PD and AD patients’ brains exhibit pure pathology with most cases presenting mixed types of protein deposits in the brain. Bimolecular fluorescence complementation (BiFC)
