Studier pekar på att en förbättrad mitokondriefunktion kan motverka åldrande generellt och parodondalt.

Cardiovascular disease is a worldwide human condition which has multiple underlying contributing factors: one of these is long-term increased blood pressure-hypertension. Nitric oxide (NO) is a small nitrogenous radical species that has a number of physiological functions including vasodilation. It can be produced enzymatically through host nitric oxide synthases and by an alternative nitrate-nitr

Introduktion: Flera studier har påpekat att det kan finnas ett samband mellan förändringar i nivån av kvinnligt könshormon och förvärrad tandlossning. Hur östrogen påverkar tandfästet är inte kartlagt. Det finns två östrogenreceptorer (ER), ERα och ERβ och betydelsen av de båda receptorerna är inte kartlagda. Målet med denna avhandling har varit att undersöka uttrycket av ER i bindvävsceller i rotAbstract INTRODUCTION: Several studies have addressed the association between changes in levels of the female sex hormone, estrogen, and changes in the parameters of periodontitis, but the mechanism behind estrogenic effects in the periodontium is poorly understood. There are two subtypes of estrogen receptors (ER), ERalpha and ERbeta. The objectives of the present studies were to map periodontal

This volume originally started as a conversation between academics from across the Arab world, all of whom have bridged their academic careers or professional development expertise to the public sphere in order to use their knowledge more actively to push for progressive, democratic change in their respective countries. Over the course of the conversation, Arab engaged scholars and activists share

Light emitting diodes (LEDs) have become the most efficient artificial lighting source. Their application is found in general indoor and outdoor lighting, headlights in automobiles, and displays whether it be TVs, laptops, mobile phones or smart watches. This technology is enabled by III-V semiconductors. Standard LEDs are comprised of stacked layers where the active region in the form of multi qu

Background: A growing literature suggests associations between occupational pesticide exposure and respiratory health. In this study, we aimed to examine the association of exposure to insecticides, fungicides, and herbicides, individually and as a mixture, with respiratory health outcomes and rhinitis in avocado farmworkers from Michoacán, Mexico. Material and methods: We conducted a cross-sectio

This study explores the variability in nutritional composition of spinach at different maturity stages and assesses the effects of fermentation on reducing oxalates and enhancing minerals bioaccessibility. Spinach harvested at the age of 4th to 6th weeks was processed as raw, blanched, and fermented to develop freeze-dried powders. The growth stages of spinach from the 4th to the 6th week showed a

The utilization of low calorific value gases (LCVG) in combustion devices presents particular challenges in terms of ignition and sustained combustion stability due to the presence of non-combustible components. Moderate or intense low-oxygen dilution (MILD) combustion has emerged as a promising technology for LCVG combustion, offering numerous advantages such as high combustion efficiency, reduce

The concept of autonomous humidity control material (AHCM) is inspired by phase change material. AHCM is a new type of functional sorbent material. It can adsorb/release sufficient water vapor at the target relative humidity level and autonomously maintain the indoor relative humidity at a set value/range without external intervention, which cannot be achieved by conventional sorbents (e.g., zeoli

A plethora of methods exist to aid decision-making in mitigating disaster risk, many of which fall into the categories of risk, vulnerability and/or resilience assessment methods. The objective of the present study is to provide an overview of these methods, with a particular focus on evidence that supports their practical implementation. A scoping study of scientific literature reveal 97 distinct

Traditional methods to study electrochemical (EC) processes, although successful, are based on current/voltage measurements, providing information about performances rather than offering a direct observation of chemical and structural changes occurring at the electrode surface. These processes are localized at the electrode-electrolyte interface, the structure of which is the main determinant of t

The osteopontin-derived peptide FOL-005 stimulates hair growth. Using ligand-receptor glyco-capture technology we identified neuropilin-1 (NRP-1), a known co-receptor for vascular endothelial growth factor (VEGF) receptors, as the most probable receptor for FOL-005 and the more stable analogue FOL-026. X-ray diffraction and microscale thermophoresis analysis revealed that FOL-026 shares binding si

Background: All-cause and AIDS-mortality in Europe has been decreasing between 1996 and 2020. However, regional differences as well as their drivers remain unclear. This study investigates mortality differences and their drivers, including usage of and response to antiretroviral therapy (ART) and active tuberculosis (TB), among people with HIV across Europe. Methods: People with HIV enrolled in Eu

This study aimed to compare long-term morbidity in patients with pulmonary atresia with intact ventricular septum (PA-IVS)treated with catheter-based intervention (group A) versus those undergoing heart surgery (group B) as initial intervention.Additionally, we conducted a systematic literature review on PA-IVS treatment. All neonates born in Sweden with PA-IVSbetween 2007 and 2019 were screened f

BACKGROUND: The medial temporal lobe (MTL) is hypothesized to be relatively spared in early-onset Alzheimer's disease (EOAD). Yet, detailed examination of MTL subfield volumes and drivers of atrophy in amnestic EOAD is lacking.METHODS: BioFINDER-2 participants with memory impairment, abnormal amyloid-β status and tau-PET were included. Forty-one EOAD individuals aged ≤65 years and, as comparison,

For more than two decades, Iran’s nuclear program has been a central focus of Europe’s engagement with Iran. Presently, with the virtual collapse of the Iran nuclearagreement (JCPOA) and Iran’s support for Russia in the war against Ukraine—coupled with the repercussions of the Mahsa Amini protests and the war in Gaza— Europe’s relations with Iran are deteriorating as Iran’s interests in Europe are
