Design, Synthesis and Aggregation of Amphiphilic Monomers—Cyclic and Tubular Hydrogen-Bonded Self-assembly in Conventional and Polar Media

Two hydrogen-bonding monomers containing tetraethylene glycol (TEG) chains have been synthesized and characterized. The monomers are based on a bicyclic scaffold appended with either 4H-bonding benzyl-substituted ureidopyrimidinone motifs or 2H-bonding unsubstituted pyrrole-fused ureidopyrimidinone motifs, with the TEG chains introduced with the aim of developing amphiphilic monomers soluble in no

Systolic inter-arm blood pressure difference and subclinical atherosclerosis : a population-based cohort study of 29921 individuals

Inter-arm blood pressure differences (IABPDs) can be caused by atherosclerosis. We investigated 29921 men and women aged 50–64years from the nationwide population-based Swedish CArdio Pulmonary bioImage Study (SCAPIS) to evaluate if IABPD is related to risk factors for atherosclerosis and can be used as a marker of atherosclerosis as evaluated by coronary artery calcium score, arterial segment inv

Therapies leading to coronary atherosclerosis plaque regression : a scientific statement of the European Association of Preventive Cardiology, the European Association of Cardiovascular Imaging of the ESC, the ESC Working Group on Atherosclerosis and Vascular Biology, and the ESC Working Group on Cardiovascular Pharmacotherapy Part 1: Atherosclerosis Pathophysiology and Imaging Evaluation

Coronary artery disease is one of the leading causes of mortality worldwide. While early identification and treatment of major cardiovascular risk factors are crucial, recent data suggest the possibility of non-invasively detecting early stages of coronary atherosclerosis and potentially stabilizing or even reversing the burden of atherosclerosis with innovative and existing treatments. Moreover,

Antecedent hypoglycaemia impairs glucagon secretion by enhancing somatostatin-mediated negative feedback control

Somatostatin, produced by pancreatic islet δ cells, is a key intra-islet paracrine factor that regulates the secretion of the glucoregulatory hormones insulin and glucagon from β cells and α cells, respectively. Here, we show that glutamate and glucagon released by α cells cooperatively activate neighbouring δ cells through AMPA and glucagon receptors, thereby enabling spatiotemporal feedback cont

Innate-like T Cell Biology in the Tumor Microenvironment Implications for Cancer Immunotherapy

Innate-like T cells (ILTCs) link innate immune responses with adaptive immune functions. This group includes invariant natural killer T (iNKT) cells, mucosa-associated invariant T (MAIT) cells, and γδ T cells. ILTCs detect transformed or stressed cells via non-classical antigen presentation pathways. For example, iNKT cells recognize CD1d-presented glycolipids, MAIT cells respond to MR1-presented

Sub-100 fs Formation of Dark Excitons in Monolayer WS2

Two-dimensional semiconducting transition metal dichalcogenides are promising materials for optoelectronic applications due to their strongly bound excitons. While bright excitons have been thoroughly scrutinized, dark excitons have been much less investigated, as they are not directly observable with far-field spectroscopy. However, with their nonzero momenta, dark excitons are significant for ap

SRPNet : stroke risk prediction based on two-level feature selection and deep fusion network

Background: Stroke is one of the major chronic non-communicable diseases (NCDs) with high morbidity, disability and mortality. The key to preventing stroke lies in controlling risk factors. However, screening risk factors and quantifying stroke risk levels remain challenging. Methods: A novel prediction model for stroke risk based on two-level feature selection and deep fusion network (SRPNet) is

Glucose regulation and association with Vitamin D and parathyroid hormone – differences across Middle Eastern and Caucasian ethnicities

Background: Middle Eastern (ME) immigrants to Europe have a heavy burden of metabolic disorders including a higher prevalence of insulin resistance, T2D and obesity as compared to native-born Europeans. Vitamin D insufficiency and deficiency are prevalent conditions in people originating from the ME. Aims: To study the differences in the levels of 25(OH)D and parathyroid hormone (PTH) across ME an

A SIRT7-dependent acetylation switch regulates early B cell differentiation and lineage commitment through Pax5

B lymphopoiesis is orchestrated by lineage-specific transcription factors. In B cell progenitors, lineage commitment is mediated by Pax5, which is commonly mutated in B cell acute lymphoblastic leukemia. Despite its essential role in immunity, the mechanisms regulating Pax5 function remain largely unknown. Here, we found that the NAD+-dependent enzyme SIRT7 coordinates B cell development through d

The Gut Microbiota and Diabetes : Research, Translation, and Clinical Applications—2023 Diabetes, Diabetes Care, and Diabetologia Expert Forum

This article summarizes the state of the science on the role of the gut microbiota (GM) in diabetes from a recent international expert forum organized by Diabetes, Diabetes Care, and Diabetologia, which was held at the European Association for the Study of Diabetes 2023 Annual Meeting in Hamburg, Germany. Forum participants included clinicians and basic scientists who are leading investigators in

GCNPMDA : Human microbe-disease association prediction by hierarchical graph convolutional network with layer attention

Microorganisms play a crucial role in various physiological processes, including metabolism, immune defense, nutrition absorption, defense against cancer, and protection against pathogen colonization. Changes in microbial communities serve as potential biomarkers for diseases, offering significant insights into disease treatment and diagnosis. However, the association between microorganisms and di

Electron-beam-induced luminescence studies of low-dimensional semiconductor structures

Cathodoluminescence (CL) in the scanning electron microscope (SEM) or the scanning transmission electron microscope (STEM) is a very useful tool for the characterization of low-dimensional semiconductor structures. To obtain spatial resolution, the SEM/STEM provides a highly focused electron beam that can be positioned at specific sites to obtain spot mode spectra. The beam can also be scanned ove

Co-occurrence of unhealthy lifestyle behaviours in middle-aged adults : findings from the Swedish CArdioPulmonary bioImage Study (SCAPIS)

Middle-aged adults engaging in unhealthy lifestyle behaviors are at higher risk of chronic diseases. However, little is known about the co-occurrence of these behaviors and their determinants. This cohort study examined the co-occurrence of unhealthy lifestyle behaviors (alcohol consumption, diet, physical inactivity, and smoking) in 30,154 middle-aged adults and their associations with sociodemog

Nutritional quality of diet characterized by the Nutri-Score profiling system and cardiovascular disease risk : a prospective study in 7 European countries

Background: Nutri-Score is a scientifically validated 5-color front-of-pack nutrition label reflecting the nutrient profile of foods. It has been implemented in several European countries on a voluntary basis, pending the revision of the European labeling regulation. Hence, scientific evidence is needed regarding the ability of the nutrient profile underlying the Nutri-Score (uNS-NPS, 2023-updated

Aminomethylations of electron-deficient compounds—bringing iron photoredox catalysis into play

The α-functionalisation of N-containing compounds is an area of broad interest in synthetic chemistry due to their presence in biologically active substances among others. Visible light-induced generation of nucleophilic α-aminoalkyl radicals as reactive intermediates that can be trapped by electron-deficient alkenes presents an attractive and mild approach to achieve said functionalisation. In th
