Sensitivity assessment of 300 Cercospora beticola isolates collected from North Greece revealed that 38 % of the population was highly resistant to at least one of the demethylase inhibitors (DMIs) difenoconazole, epoxiconazole and flutriafol. Resistance factors greater than 50, 100 and 100 were calculated for the most resistant C. beticola isolates to flutriafol, epoxiconazole and difenoconazole, respectively.

Developing efficient, sustainable, earth-abundant, cost-effective electrocatalysts is extremely challenging. Cobalt-iron-layered double hydroxide nanosheets (Co-Fe-LDH NSs) hybridized with carbon nanotubes (CNTs) lead to anchors Co-Fe-LDH-CNTs (CFC) self-assembly with a mesoporous morphology, expanded surface area, fast charge transfer kinetics, and high electrical conductivity. The resultant anchored CFC nanohybrid is highly active for electrocatalytic oxygen evolution reaction (OER), showing a lower overpotential of 221 and 313 mV at a current density of 10 and 25 mA cm, respectively, compared to pristine Co-Fe-LDH (339 and 391 mV), showcasing the significant role of CNTs in improving the electrocatalytic performance of pristine Co-Fe-LDH.

Objective: This study aimed to evaluate the effectiveness of cognitive behavioural therapy (CBT), parent training programm (PTPs), and their combination as adjunctive interventions to medication in reducing core ADHD symptoms and functional difficulties in children aged 7-11 who had been receiving pharmacological treatment. The goal was to examine whether these psychosocial approaches could enhance treatment outcomes beyond medication alone.

Method: Forty-two mother-child dyads were randomly assigned to one of four groups: (1) medication (M) plus cognitive behavioural therapy (CBT), (2) M plus parent training programme (PTP), (3) M plus both CBT and PTP (combined), and (4) M only (control).

Study Question: What is the diagnostic yield and the pre-testicular sperm extraction (TESE) prognostic value of a non-obstructive azoospermia (NOA)-specific virtual gene panel?

Summary Answer: The diagnostic yield in our cohort was 6.1%, and by combining our data with published literature, we identified 11 genes compatible with testicular sperm production and 19 genes associated with no sperm retrieval in carriers of pathogenic (P) or likely pathogenic (LP) mutations.

What Is Known Already: Azoospermia, the most severe form of male infertility, affects ∼1% of the male population, with TESE being the primary treatment option.

In this study, graphene oxide (GO) was synthesized via a modified low-temperature Hummer's method and incorporated into a poly (ethylene oxide) (PEO) matrix to fabricate PEO/GO nanocomposite thin films using a casting technique. This work explores how GO incorporation affects the structural and optical properties of PEO, with emphasis on its suitability for optical switching and other optoelectronic applications. The films were prepared with varying GO concentrations and characterized using XRD, UV-Vis spectroscopy, and other standard techniques.

Geranylgeranyl pyrophosphate, a non-sterol intermediate of the mevalonate pathway, serves as the substrate for protein geranylgeranylation, a process catalyzed by geranylgeranyl transferase I (GGTase-I). Myeloid-specific deletion of Pggt1b, the gene coding for GGTase-I, leads to spontaneous and severe erosive arthritis in mice; however, the underlying mechanisms remained unclear. In this study, we demonstrate that arthritis in mice with myeloid-specific Pggt1b deficiency is driven by unprenylated GTP-bound small RHO family GTPases, which in turn trigger Pyrin (Mefv) inflammasome activation, GSDMD-dependent macrophage pyroptosis, and IL-1β secretion.

The precise detection and localization of abnormalities in radiological images are very crucial for clinical diagnosis and treatment planning. To build reliable models, large and annotated datasets are required that contain disease labels and abnormality locations. Most of the time, radiologists face challenges in identifying and segmenting thoracic diseases such as COVID-19, Pneumonia, Tuberculosis, and lung cancer due to overlapping visual patterns in X-ray images.

Hyperglycemia in early-stage embryogenesis is linked to diabetic embryopathy. High-glucose-concentration-induced accumulation of hexokinase-2 (HK2) may initiate metabolic dysfunction that contributes to diabetic embryopathy, including increased formation of methylglyoxal (MG). In this study, we evaluated changes in HK2 protein levels and embryo dysmorphogenesis in an experimental model of diabetic embryopathy.

Glyoxalase 1 Inducer, -Resveratrol and Hesperetin-Dietary Supplement with Multi-Modal Health Benefits.

Antioxidants (Basel)

August 2025

Diabetes Research Center, Qatar Biomedical Research Institute, Hamad Bin Khalifa University, Qatar Foundation, Doha P.O. Box 34110, Qatar.

A dietary supplement, -resveratrol and hesperetin (tRES+HESP)-also known as GlucoRegulate-induces increased expression of glyoxalase 1 (Glo1) by activation of transcription factor Nrf2, countering accumulation of the reactive dicarbonyl glycating agent, methylglyoxal. tRES+HESP corrected insulin resistance and decreased fasting and postprandial plasma glucose and low-grade inflammation in overweight and obese subjects in a clinical trial. The aim of this study was to explore, for the first time, health-beneficial gene expression other than Glo1 induced by tRES+HESP in human endothelial cells and fibroblasts in primary culture and HepG2 hepatoma cell line and activity of -resveratrol (cRES) as a Glo1 inducer.

Background: Dexamethasone has been demonstrated to be a potential treatment approach preventing COVID-19 related fatalities by managing the cytokine release storm (CRS). The expression of the inflammatory mediators involved in the CRS is regulated by the circadian biology of the immune response and it peaks during the evening. Accordingly, it has been hypothesized that the administration of anti-inflammatory medications in the evening could help better manage the CRS.

Fetal echocardiography offers non-invasive and real-time imaging acquisition of fetal heart images to identify congenital heart conditions. Manual acquisition of standard heart views is time-consuming, whereas automated detection remains challenging due to high spatial similarity across anatomical views with subtle local image appearance variations. To address these challenges, we introduce a very lightweight frequency-guided deep learning-based model named HarmonicEchoNet that can automatically detect heart standard views in a transverse sweep or freehand ultrasound scan of the fetal heart.
