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

Genetic Variation Interacts with Selenium Exposure Regarding Breast Cancer Risk: Assessing Dietary Intake, Serum Levels and Genetically Elevated Selenium Levels

Selenium has been suggested to be protective regarding breast cancer risk but no overall effect has been established. Genetics may modify the effect. This study compares the effect of selenium exposure on breast cancer risk between women with different alleles in single-nucleotide polymorphisms (SNPs). The Malmö Cancer and Diet Study, a cohort including 17,035 women and >25 years of follow-up on b

Assessing the impacts of social norms on low-carbon mobility options

Policymakers and scientists are paying increasing attention to how social norms can promote pro-environmental behaviour and sustainable energy use. We contribute to this field by experimenting with and assessing the impacts of social norms on low-carbon mobility options. Taking Sweden as a case study, we develop two complementary randomised controlled experiments to: 1) analyse the role of social

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.

Humlesugan och skottskogen – en jämförelse mellan Lolland och Skåne

När skottskogsbruket/stubbskottsängsbruket upphörde i början av 1800-talet försvann även landskapet som humlesugan, Betonica officinalis L., var anpassad till. Från att ha varit allmän på sydvästra Lolland och i västra Mellanskåne blev den mycket sällsynt inom dessa kärnområden i humlesugans tidigare utbred- ning i Skandinavien. Ändå lyckades den överleva på sju lokaler. För att bevara dessa krävsWhen coppice forestry and the use of wooded meadows ceased in the early 19th century, the landscape to which Betony, Betonica officinalis L., was adapted also disappeared. From being common in southwestern Lolland and in western Mid­Skåne, it became very rare in these core areas of Betony’s earlier distribution in Scandi­ navia. However, the species has managed to survive at seven localities and t

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

Final Targeting Strategy for the Sloan Digital Sky Survey IV Apache Point Observatory Galactic Evolution Experiment 2 North Survey

The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemodynamical mapping of the Milky Way. The targeting for APOGEE-2 is complex and has evolved with time. In this paper, we present the updates and additions to the initial targeting strategy for APOGEE-2N presented in Zasowski et al.

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

PEPRF : Identification of Essential Proteins by Integrating Topological Features of PPI Network and Sequence-based Features via Random Forest

Background: Essential proteins play an important role in the process of life, which can be identified by experimental methods and computational approaches. Experimental approaches to identify essential proteins are of high accuracy but with the limitation of time and resource-consuming. Objective: Herein, we present a computational model (PEPRF) to identify essential proteins based on machine lear

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
