Progesterone distribution in the trigeminal system and its role to modulate sensory neurotransmission : influence of sex

Background: Women are disproportionately affected by migraine, representing up to 75% of all migraine cases. This discrepancy has been proposed to be influenced by differences in hormone levels between the sexes. One such hormone is progesterone. Calcitonin gene-related peptide (CGRP) system is an important factor in migraine pathophysiology and could be influenced by circulating hormones. The pur

Institutional Complexity and Political Agency in Polycentric Governance

This chapter addresses the ways in which the complexity of global governance enables or constrains political agency. An increasingly complex global institutional system—with its growing level of unpredictability and uncertainties—challenges some of the classical institutionalist tenets in respect of conditions of power and agency. For instance, the capacities of central governance institutions and

Consumption of ultra-processed foods and risk of multimorbidity of cancer and cardiometabolic diseases : a multinational cohort study

Background: It is currently unknown whether ultra-processed foods (UPFs) consumption is associated with a higher incidence of multimorbidity. We examined the relationship of total and subgroup consumption of UPFs with the risk of multimorbidity defined as the co-occurrence of at least two chronic diseases in an individual among first cancer at any site, cardiovascular disease, and type 2 diabetes.

Interleukin-1 receptor accessory protein (IL-1RAP) : A magic bullet candidate for immunotherapy of human malignancies

IL-1, plays a role in some pathological inflammatory conditions. This pro-inflammatory cytokine also has a crucial role in tumorigenesis and immune responses in the tumor microenvironment (TME). IL-1 receptor accessory protein (IL-1RAP), combined with IL-1 receptor-1, provides a functional complex for binding and signaling. In addition to the direct role of IL-1, some studies demonstrated that IL1

Beyond the language network : Associations between reading, receptive vocabulary, and grey matter volume in 10-year-olds

Most research on the neurostructural basis of language abilities in children stems from small samples and surface-based measures. To complement and expand the existent knowledge, we investigated associations between grey matter volume and language performance in a large sample of 9-to-11-year-old children, using data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 1865) and an al

Paradigm Shift in the Management of Metabolic Diseases—Next-Generation Incretin Therapy

Recently impressive weight loss has been reported for novel incretin therapies based on dual-and triple-hormone receptor coagonists. These agents have potential as being positioned as early therapeutics for metabolic diseases for which weight loss is preferred, such as type 2 diabetes, obesity, cardiovascular diseases, and nonalcoholic liver disease. This development will change the landscape of f

Exploring different methodological approaches to unlock paleobiodiversity in peat profiles using ancient DNA

Natural and human-induced environmental changes deeply affected terrestrial ecosystems throughout the Holocene. Paleoenvironmental reconstructions provide information about the past and allow us to predict/model future scenarios. Among potential records, peat bogs are widely used because they present a precise stratigraphy and act as natural archives of highly diverse organic remains. Over the dec

Trajectories of primary health care utilization : a 10-year follow-up after the Swedish Patient Choice Reform of primary health care

Background: In January 2010, the choice reform was instituted in Swedish primary health care establishing free entry for private primary health care providers and enabling patients to choose freely among primary health care centers. The motivation behind the reform was to improve access to primary care and responsiveness to patient expectations. Reform effects on health care utilization have previ

EDGE : The direct link between mass growth history and the extended stellar haloes of the faintest dwarf galaxies

Ultra-f aint dw arf galaxies (UFDs) are commonly found in close proximity to the Milky Way and other massive spiral galaxies. As such, their projected stellar ellipticity and extended light distributions are often thought to owe to tidal forces. In this paper, we study the projected stellar ellipticities and faint stellar outskirts of tidally isolated ultra-faints drawn from the 'Engineering Dwarf

Bridging differences through classroom simulations : Teaching Global Environmental Governance to international and interdisciplinary PhD students

The course Global Environmental Governance Today–Actors, Institutions, Complexity is an in- terdisciplinary PhD course and has welcomed participants from a wide range of disciplinary backgrounds with equally varied prior knowledge on environmental governance practices and theories. Thus, every year, participants include students who are not familiar with international relations theories such as re

Clinical outcomes up to 9 years after [18F]flutemetamol amyloid-PET in a symptomatic memory clinic population

Background: Previous studies demonstrated increases in diagnostic confidence and change in patient management after amyloid-PET. However, studies investigating longitudinal outcomes over an extended period of time are limited. Therefore, we aimed to investigate clinical outcomes up to 9 years after amyloid-PET to support the clinical validity of the imaging technique. Methods: We analyzed longitud

Dietary intakes of dioxins and polychlorobiphenyls (PCBs) and mortality : EPIC cohort study in 9 European countries

Dioxins and polychlorinated biphenyls (PCBs) are toxic, endocrine disruptors and persistent chemicals for which the main exposure source is diet due to their bioaccumulation and biomagnification in food chains. Cohort studies in the general populations have reported inconsistent associations between these chemicals in serum/plasma and mortality. Our objective was to study the association between d

Rationale and design of the DAPA-MI trial : Dapagliflozin in patients without diabetes mellitus with acute myocardial infarction

Background: Therapies that could further prevent the development of heart failure (HF) and other cardiovascular and metabolic events in patients with recent myocardial infarction (MI) represent a large and unmet medical need. Methods: DAPA-MI is a multicenter, parallel-group, registry-based, randomized, double-blind, placebo-controlled phase 3 trial in patients without known diabetes or establishe

Knowing a fellow by their bellow : acoustic individuality in the bellows of the American alligator

Identity cues in animal calls are essential for conspecific vocal individual recognition. Some acoustically active species mainly show reliable identity cues in their vocalizations because of variation in anatomy and life history. Long and strenuous-to-produce vocalizations may be particularly effective for showing identity cues because sustaining such calls may reveal individual anatomical differ

Aging and Alzheimer's disease have dissociable effects on local and regional medial temporal lobe connectivity

Functional disruption of the medial temporal lobe-dependent networks is thought to underlie episodic memory deficits in aging and Alzheimer's disease. Previous studies revealed that the anterior medial temporal lobe is more vulnerable to pathological and neurodegenerative processes in Alzheimer's disease. In contrast, cognitive and structural imaging literature indicates posterior, as opposed to a

Impact of autofluorescence for detection of parathyroid glands during thyroidectomy on postoperative parathyroid hormone levels : parallel multicentre randomized clinical trial

Background: Techniques for autofluorescence have been introduced to visualize the parathyroid glands during surgery and to reduce hypoparathyroidism after thyroidectomy. Methods: This parallel multicentre RCT investigated the use of Fluobeam® LX to visualize the parathyroid glands by autofluorescence during total thyroidectomy compared with no use. There was no restriction on the indication for su

Displacement of PAMAM-Au via acoustic streaming on an electrochemical immunosensing platform

The displacement of an electroactive monitoring agent, i.e., polyamidoamine dendrimers encapsulated gold nanoparticles (PAMAM-Au) upon the presence of a target antibody via acoustic streaming has been studied. Acoustic streaming has been used to improve the mass transfer and reduce the sample incubation rate, thus this study investigated its ability in enhancing the PAMAM-Au displacement efficienc
