Aging is the primary risk factor for most neurodegenerative diseases, yet the cell-type-specific progression of brain aging remains poorly understood. Here, human cell-type-specific transcriptomic aging clocks are developed using high-quality single-nucleus RNA sequencing data from post mortem human prefrontal cortex tissue of 31 donors aged 18–94 years, encompassing 73,941 high-quality nuclei. Di
The photoelectric effect explained by Einstein is often regarded as a one-electron phenomenon, whereas the interaction of the escaping electron with other electrons, referred to as electron correlation, plays an important role in multielectron systems. In this Letter, we study the attosecond photoionization of the outer s subshell of argon in its substantial minimum cross-section region formed by
Transition metal complexes featuring ligand-to-metal charge transfer (LMCT) excited states have been identified as promising candidates for driving electron transfer processes. To obtain an efficient system based on photo-induced bimolecular electron transfer, it is required that (1) photo-induced charge separation (CS) is faster than charge recombination (CR) of the separated charges, and (2) CR
AimTo explore the meaning of lived experiences of women with a hereditary risk of breast cancer who participate in surveillance of their breasts with magnetic resonance imaging.DesignHermeneutic phenomenology.MethodsInterviews on two occasions were made with 14 women in the surveillance programme. The verbatim transcripts were analysed according to van Manen. The analysis was an insightful iterati
Depression is a common, recurrent disorder. There is a need for readily available treatments with few negative side effects, that demands little resources and that are effective both in the short- and long term. Our aim was to investigate the long-term effectiveness of two different interventions; physical exercise and internet-based cognitive behavioural therapy (internet-CBT), compared to usual
Three-dimensional brain organoids have emerged as a valuable model system for studies of human brain development and pathology. Here we establish a midbrain organoid culture system to study the developmental trajectory from pluripotent stem cells to mature dopamine neurons. Using single cell RNA sequencing, we identify the presence of three molecularly distinct subtypes of human dopamine neurons w

Background: Induced hypothermia after cardiac arrest is neuroprotective in several animal models of cardiac arrest, but few high-quality studies have been conducted in larger animals. Recent clinical trials have questioned the beneficial effects of post-ischemic hypothermia. This study investigated whether immediate cooling or a 2-h delay in cooling to 33 °C after cardiac arrest was neuroprotectiv
BACKGROUND AND OBJECTIVES: The association between dairy intake and dementia risk remains uncertain, especially for dairy products with varying fat contents. The aim of this study was to investigate the association between high-fat and low-fat dairy intake and dementia risk.METHODS: This study used data from a prospective cohort in Sweden, the Malmö Diet and Cancer cohort, which consisted of commu
Droplets are sophisticated micro-compartments crucial for lab-on-a-chip and bio-medical applications. There have been significant efforts towards generating monodisperse droplets as the uniformity of droplets affects performance. Recently, we introduced a new method to continuously reform existing emulsions improving monodispersity in an ultrasound-actuated microcavity via a trap-coalesce-split me
Organoid systems hold promise as miniaturized in vitro platforms that model developmental and pathological processes. However, the engineering of human bone marrow organoids (BMOs) has been a long-standing challenge. Recently, the field has witnessed the emergence of BMO-like systems, a potential paradigm shift for the study of human hematopoiesis and associated niche elements. Published protocols
INTRODUCTION: In Sweden, most older adults continue to age in dwellings they have lived in for many years, with a small proportion relocating. Longitudinal studies examining relocation histories, especially among younger old adults and those beyond frail populations, are scarce. This study aimed to describe individuals who stayed in their homes (stayers) and those who relocated (movers) while iden
Objective: Although previous studies have shown reduced cardiovascular events following parathyroidectomy (PTX), it is unclear whether this extends to contemporary patients diagnosed and treated with milder disease than previously. The aim of this nation-wide study was to determine the effect on cardiovascular events after PTX, and to comprehensively evaluate cardiovascular disease manifestations
Background: Influenza ranges from a mild and self-limiting infection to a life-threatening disease with high mortality despite intensive care. Conclusive data on the association between influenza type/subtype and mortality among adults treated at intensive care units (ICU) is lacking. Objectives: To investigate the mortality in adults admitted to ICU with laboratory-confirmed influenza during thre
Alzheimer’s disease (AD) is marked by the abnormal aggregation of amyloid-beta peptides within the central nervous system. The formation of amyloid fibrils from amyloid-beta peptides is a hallmark of AD Here, we demonstrate that the aggregation of amyloid-beta 42 spreads both spatially and temporally. By measuring the spatial propagation of amyloid-beta in macroscopic capillaries and performing Mo
We investigate the influence of AlN buffer thickness on the structural, electrical, and thermal properties of AlGaN/GaN high-electron mobility transistors (HEMTs) grown on semi-insulating SiC substrates by metal-organic chemical vapor deposition. X-ray diffraction and atomic force microscopy reveal that while thin AlN layers (120 nm) exhibit compressive strain and smooth step-flow surfaces, thicke
Introduction: Oesophageal resection carries significant morbidity and mortality. Artificial intelligence (AI) advances in medical research enable enhanced predictions, flexibility, and interpretability, especially for complex interactions and nonlinear relationships. Material and methods: We used a register-based case-control design nested within prospectively collected data from the Swedish Natio
The instability of perovskite interfaces caused by interfacial defects and heterojunction evolution hinders the realization of long-term stable inverse perovskite solar cells (IPSCs). This work reports a strategy for the study of heterojunction evolution, the effects of buried interface and carrier dynamics on the stability of perovskite films and devices in 2D/3D heterojunctions. The emphasis is
