Cortical interneuron deficiencies, particularly involving the somatostatin (SST) subtypes, contribute to neurological and neuropsychiatric disorders. These interneurons are difficult to derive in vitro from human embryonic stem cells (hESCs) due to their late embryonic development and dependence on glial interaction. To this end, we developed a three-dimensional co-culture model of hESC-derived ne

Apolipoprotein E4 (ApoE4), the major genetic risk factor for Alzheimer's disease (AD), is vital for understanding cellular processes involved in AD pathogenesis. Evidence implicates endosomes as a central player in AD, where endosomal enlargement in neurons is among the earliest changes in AD. This enlargement was reported to be enhanced in APOE4 carriers. Cells internalize ApoE into endosomes for

PURPOSE: Given the paucity of data regarding workplace risk of COVID-19, particularly from countries with limited lockdowns, we aimed to quantify the occupational risks of COVID-19-related hospital admission among workers in Sweden.METHODS: We identified 607,179 employed individuals, 20-69 years of age, in Skåne, Sweden. From December 31st, 2019-December 31st 2021, 2,633 incident COVID-19-related

III-Nitride high-electron mobility transistors (HEMTs) grown on AlN substrates offer significant advantages for high-power, high-frequency applications due to AlN high thermal conductivity and ultra-wide bandgap. However, achieving high-quality thin GaN channel layers on AlN is challenging because of lattice mismatch, which leads to columnar growth. In this work, we present the development of a tw

Objective: To determine bone shape changes over two years after acute anterior cruciate ligament (ACL) injury and to compare knees treated with ACL reconstruction (ACLR) vs no ACLR. Design: We used prospective data involving 129 young adults (46 ​% female, mean age 25 years) with recent ACL injury from a subcohort within the prospective multicenter NACOX study. Patients were treated according to S

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

Adolescent girls are particularly susceptible to iron deficiency due to increased iron requirements during the pubertal growth spurt, combined with iron loss following menarche. This study aimed to investigate the prevalence of heavy menstrual bleeding in an adolescent population using the SAMANTA questionnaire and to explore its relationship with dietary habits and iron deficiency. This cross-sec

Bakgrund: God kommunikativ och empatisk förmåga hos läkare skapar trygghet och upplevs som professionellt av patienter och närstående. Forskning visar att empati förbättrar patienters följsamhet, nöjdhet och relationen mellan läkare och patient, vilket i sin tur leder till högre vårdkvalitet, bättre behandlingsresultat och minskade vårdkostnader. Ett empatiskt förhållningssätt främjar både fysisk

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

Single-cell and single-nuclei RNA-sequencing (scRNA-seq and snRNA-seq) analyze cell-specific transcriptomes. However, only snRNA-seq applies to frozen biobanked samples. For human pancreatic islets, marker genes and reference-based cell type annotation methods are mainly from scRNA-seq datasets and may not be suitable for snRNA-seq. We compared human islet scRNA-seq and snRNA-seq data from the sam

This study presents a cryogenic resonant radio frequency (RF) transmitter coil design for magnetic field generation that utilizes electromechanical switches to match and tune the resonance frequency with capacitor banks in situ. The design enables magnetic field generation at any frequency across a wide frequency range of 25-140 MHz (560% tuning range) while operating at 1.5 K. Magnetic field gene

Background Breast cancer is the most frequently diagnosed cancer in women. Survival is generally considered favourable, yet some patients remain at risk of early death. We aimed to assess whether comprehensive whole-genome sequencing (WGS) linked to mortality data could add prognostic value to existing clinical measures and identify patients who might respond to targeted therapeutics. Methods In t

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

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

INTRODUCTION: As the world population is rapidly becoming older, the incidence of traumatic brain injury (TBI) is increasing among older adults with vast implications for brain health of older adults in Europe. Due to differences from younger patients, there are areas of uncertainty in the assessment, diagnosis and management of TBI in older adults.RESEARCH QUESTION: To reach a consensus among exp
