Novel serum biomarkers for early diagnosis of gestational diabetes mellitus-a review.

Gestational diabetes mellitus (GDM) affects 9-25% of pregnancies. Undiagnosed or poorly managed GDM is associated with both short- and long-term complications in the fetus and mother. The pathogenesis of GDM is complex and has not yet been fully elucidated.

Kinetics of Macroion Adsorption on Silica: Complementary Theoretical and Experimental Investigations for Poly-l-arginine.

A comprehensive approach enabling a quantitative interpretation of poly-l-arginine (PARG) adsorption kinetics at solid/electrolyte interfaces was developed. The first step involved all-atom molecular dynamics (MD) modeling of physicochemical characteristics yielding PARG molecule conformations, its contour length, and the cross-section area. It was also shown that PARG molecules, even in concentrated electrolyte solutions (100 mM NaCl), assume a largely elongated shape with an aspect ratio of 36.

Pressure-induced phase transitions in a new luminescent gold(I)-arylacetylide.

Stimulus-responsive molecular materials are highly desirable because of the wide range of their potential applications. In particular, switching of physical properties opens application pathways for molecular materials as sensors or actuators. Property switching in solids can be achieved by inducing single-crystal-to-single-crystal (SCSC) phase transitions.

Resistant Renovascular Hypertension in Youth: Fibromuscular Dysplasia or Takayasu Arteritis?

BACKGROUND Arterial hypertension in pediatric patients often presents complex diagnostic and therapeutic challenges. The diagnosis of hypertension in children is based on different guidelines than in adults, with arterial hypertension in children defined as systolic and/or diastolic blood pressure values at or above the 95th percentile for age, sex, and height. Unlike adult populations, it is predominantly secondary in etiology, with conditions such as renovascular hypertension as common causes.

In women, several factors, including pregnancy and vaginal delivery, can affect pelvic muscle conditions. The aim of the study was to perform a genetic analysis in young women with a family history of pelvic floor dysfunction to find potentially harmful variants or variants that increase the risk of developing pelvic floor disorders.

Targeting GABA signaling in type 1 diabetes and its complications- an update on the state of the art.

Type 1 diabetes (T1D) is an autoimmune disease that leads to the progressive destruction of insulin-producing β cells, resulting in lifelong insulin dependence and a range of severe complications. Beyond conventional glycemic control, innovative therapeutic strategies are needed to address the underlying disease mechanisms. Recent research has highlighted gamma-aminobutyric acid (GABA) as a promising therapeutic target for T1D due to its dual role in modulating both β cell survival and immune response within pancreatic islets.

Trust in scientists and their role in society across 68 countries.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists.

Machine learning validation of the AVAS classification compared to ultrasound mapping in a multicentre study.

The Arteriovenous Access Stage (AVAS) classification simplifies information about suitability of vessels for vascular access (VA). It's been previously validated in a clinical study. Here, AVAS performance was tested against multiple ultrasound mapping measurements using machine learning.

Investigating canonical size phenomenon in drawing from memory task in different perceptual conditions among children.

The canonical size phenomenon refers to the mental representation of real-object size information: the objects larger in the physical world are represented as larger in mental spatial representations. This study tested this phenomenon in a drawing-from-memory task among children aged 5, 7, and 9 years. The participants were asked to draw objects whose actual sizes varied at eight size rank levels.

Perceptions of science, science communication, and climate change attitudes in 68 countries - the TISP dataset.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Long term study on blood glucose levels in wintering great tits Parus major in sites differing in artificial food availability.

Blood glucose concentration is one of the fundamental biochemical indices in the physiology of birds and other vertebrates. Since glucose serves as the main fuel for metabolic energy, its proper level in the blood serum is crucial to the individual in terms of physiological health, which leads to applying it as an ecophysiological indicator. Such an indicator may be especially useful during energetically demanding periods, such as winter at northern latitudes.

A customizable multiplex protein microarray for antibody testing and its application for tick-borne and other infectious diseases.

Tick-borne infections are the most common vector-borne diseases in the USA. Ticks harbor and transmit several infections with Lyme disease being the most common tickborne infection in the US and Europe. Lack of awareness about tick populations, specific diagnostic tests, and overlapping signs and symptoms of tick-borne infections can often lead to misdiagnosis affecting treatment and the prevalence data reported especially for non-Lyme tick-borne infections.

Plasma transfusions in neonatal intensive care units: a prospective observational study.

Objective: Despite lack of evidence supporting efficacy, prophylactic fresh frozen plasma and Octaplas transfusions may be administered to very preterm infants to reduce bleeding risk. International variation in plasma transfusion practices in neonatal intensive care units (NICUs) is poorly understood, therefore, we aimed to describe neonatal plasma transfusion practice in Europe.

Design: Prospective observational study.

Use of laser-ablation inductively-coupled mass spectroscopy for analysis of selenosugars bound to proteins.

We previously used high pressure liquid chromatography (HPLC) coupled with Se-specific inductively coupled plasma mass spectrometry (ICP-MS) and molecule specific (ESI Orbitrap MS/MS) detection to study the increase in liver Se in turkeys and rats supplemented as selenite in high-Se (5 µg Se/g diet) and adequate-Se diets. We found that far more Se is present as selenosugar (seleno-N-acetyl galactosamine) than is present as selenocysteine (Sec) in true selenoproteins. In high-Se liver, the increase in liver Se was due to low molecular weight (LMW) selenometabolites as glutathione-, cysteine- and methyl-conjugates of the selenosugar, but also as high molecular weight (HMW) species as selenosugars decorating general proteins via mixed-disulfide bonds.

Modern Approach to Testing the Biocompatibility of Osteochondral Scaffolds in Accordance with the 3Rs Principle─Preclinical , , and Studies Using the Biphasic Curdlan-Based Biomaterial.

Timing of exercise differentially impacts adipose tissue gain in male adolescent rats.

Circadian rhythms of metabolic, hormonal, and behavioral fluctuations and their alterations can impact health. An important gap in knowledge in the field is whether the time of the day of exercise and the age of onset of exercise exert distinct effects at the level of whole-body adipose tissue and body composition. The goal of the present study was to determine how exercise at different times of the day during adolescence impacts the adipose tissue transcriptome and content in a rodent model.

Raman, ROA, and luminescence spectra of chiral lanthanide complexes with L- and D-alanine.

The Raman spectra of lanthanide [Ln(HO)(Ala)](ClO) crystals were measured with 488, 532, 633, and 1064 nm laser lines, and ROA of complexes in water were collected using 532 nm excitation. As in IR and VCD, ν(CO) stretching and β(OCO) bending vibration bands showed a tendency typical to the lanthanide contraction effect. However, in Raman, the effect is less pronounced than the IR spectrum because it is strongly perturbed by lanthanide ion luminescence, which comes from the 4f → 4f transitions.

Urban flood dilemmas: How European cities growth shapes flood risk and resilience strategies?

Extensive research across European cities underscores the importance of assessing urbanization's impact on flood risk, focusing on river-induced floods and impermeable areas. Using advanced statistical tools, we investigated urban green coverage, Urban Morphological Zones (UMZ), and sealing (imperviousness) levels and effects. Our analysis found that Continuous Urban Fabric (sealed surface >80%) and Discontinuous Dense Urban Fabric (sealed surface 50%-80%) showed negative relationships within river flooding risk.

Antigenicity evaluation of the synthetic trisaccharides related to Plesiomonas shigelloides serotype O51 O-antigen containing an acetamidino group.

Bacterial surface polysaccharides are widely decorated with diverse rare functional groups. An understanding of the role of these functional groups in immunological activity of the glycans is required for the development of carbohydrate-based treatment against bacterial infectious diseases. Here, the antigenicity evaluation of synthetic trisaccharide 1 related to Plesiomonas shigelloides serotype O51 lipopolysaccharide (LPS) O-antigen and its acetamido derivative 2 was achieved to elucidate the immunological importance of O-antigen structure.

Design of experiments method into upgrading pyrolytic oil for sustainable aviation fuel additives by hydrotreating and hydrocracking.

Recycling waste to produce liquid fuels for the automotive and aviation industries is a major global concern, especially in light of the ongoing energy crisis. Because waste is used in thermal conversion processes, the resulting liquid products often require additional processing to reduce their density and viscosity, and to remove oxygenated compounds or pollutants that hinder further utilization. Catalytic hydrogenolytic reactions such as hydrodeoxygenation (HDO) and hydrocracking (HC) have been extensively applied to upgrade pyrolysis oils.
