α-FeO and polypyrrole impregnated alginate/gelatin nanocatalysts for the reduction of azo dyes and persistent organic pollutants.

Herein, we propose magnetic nanocomposites as a powerful new catalyst for organic pollutant reduction. Polypyrrole (PPy) was synthesized in situ within the semi-interpenetrating alginate (Alg)/gelatin (Ge) network in presence of α-FeO as encapsulating matrix and inorganic filler, respectively. The polymeric matrix can act as bifunctional agent such as a binder and stabilizer to improve nanocatalyst stability while preserving their catalytic/magnetic performances.

Dichloroacetate and chloroquine in combination with arsenite suppress ROS-induced oral squamous cell carcinoma (OSCC) development and improve BALB/c mice survival.

Here, we sought to explore a new chemotherapeutic approach based on a combined induction of cytotoxic ROS and targeting of autophagy and aerobic glycolysis as central contributors to OSCC carcinogenesis and chemoresistance. To this end, tongue OSCC was generated in BALB/c mice using 4NQO.

Highlighting chromosomal rearrangements of five species of Galliformes (Domestic fowl, Common and Japanese quail, Barbary and Chukar partridge) and the Houbara bustard, an endangered Otidiformes: banding cytogenetic is a powerful tool.

Birds are one of the most diverse groups among terrestrial vertebrates. They evolved from theropod dinosaurs, are closely related to the sauropsid group and separated from crocodiles about 240 million years ago. According to the IUCN, 12% of bird populations are threatened with potential extinction.

Monte Carlo study of organ doses and related secondary cancer risk estimations for patients undergoing prostate radiotherapy: Algerian population-based study.

The present study aimed to assess organ doses and the associated cancer risks related to secondary radiation (photons and neutrons) exposure during 3D Conformational Radiotherapy (3D-CRT) for patients with prostate cancer in Algeria.

High Capacity and Reversible Fragile Watermarking Method for Medical Image Authentication and Patient Data Hiding.

The exchange of medical images and patient data over the internet has attracted considerable attention in the past decade, driven by advancements in communication and health services. However, transferring confidential data through insecure channels, such as the internet, exposes it to potential manipulations and attacks. To ensure the authenticity of medical images while concealing patient data within them, this paper introduces a high-capacity and reversible fragile watermarking model in which an authentication watermark is initially generated from the cover image and merged with the patient's information, photo, and medical report to form the global watermark.

Performance of artificial intelligence model (LSTM model) for estimating and predicting water quality index for irrigation purposes in order to improve agricultural production.

The primary goal of this study is to predict the current and future water quality index for irrigation (WQII) of the western Mitidja alluvial aquifer in northern Algeria. The modified WQII was used to evaluate groundwater suitability for irrigation through geographic information system (GIS) techniques. Additionally, a long short-term memory (LSTM) model was employed to calculate the WQII and map future groundwater quality, considering factors like overexploitation, anthropogenic pollution, and climate change.

Crucial Interactions between Altered Plasma Trace Elements and Fatty Acids Unbalance Ratio to Management of Systemic Arterial Hypertension in Diabetic Patients: Focus on Endothelial Dysfunction.

The coexistence of SAH with T2DM is a common comorbidity. In this study, we investigated the link between altered plasma antioxidant trace elements (ATE: manganese, selenium, zinc, and copper) and fatty acids ratio (FAR: polyunsaturated/saturated) imbalance as transition biomarkers between vascular pathology (SAH) to metabolic pathology (T2DM). Our data revealed strong correlation between plasma ATE and FAR profile, which is modified during SAH-T2DM association compared to the healthy group.

Silver decorated zeolite embedded in bionanocomposite hydrogels based on cross-linked carboxymethyl cellulose for excellent catalytic hydrogenation of azo dyes.

Herein, bionanocomposite beads based on Carboxymethyl cellulose/Dextrant sulfate (CMC/DS) embedding silver nanoparticle-functionalized zeolite (AgZ) were developed and proposed as catalysts for catalytic hydrogenation of Direct Red 16 (DR16) azo dye under different experimental parameters. The obtained results showed that AgZ incorporation into the polymer matrix produced highly porous structures with improved thermal stability. For antibacterial application, it was shown that the engineered bionanocomposites were effective against all tested bacteria.

Transformer-based deep learning networks for fault detection, classification, and location prediction in transmission lines.

Fault detection, classification, and location prediction are crucial for maintaining the stability and reliability of modern power systems, reducing economic losses, and enhancing system protection sensitivity. This paper presents a novel Hierarchical Deep Learning Approach (HDLA) for accurate and efficient fault diagnosis in transmission lines. HDLA leverages two-stage transformer-based classification and regression models to perform Fault Detection (FD), Fault Type Classification (FTC), and Fault Location Prediction (FLP) directly from synchronized raw three-phase current and voltage samples.

Low-dose dimethylfumarate attenuates colitis-associated cancer in mice through M2 macrophage polarization and blocking oxidative stress.

Colitis-associated cancer (CAC) is an aggressive subtype of colorectal cancer that can develop in ulcerative colitis patients and is driven by chronic inflammation and oxidative stress. Current chemotherapy for CAC, based on 5-fluorouracil and oxalipltin, is not fully effective and displays severe side effects, prompting the search for alternative therapies. Dimethylfumarate (DMF), an activator of the nuclear factor erythroid 2-related factor 2 (NRF2), is a potent antioxidant and immunomodelatrory drug used in the treatment of multiple sclerosis and showed a strong anti-inflammatory effect on experimental colitis.

Exploring the relationship between oxidative stress status and inflammatory markers during primary Sjögren's syndrome: A new approach for patient monitoring.

Introduction: Primary Sjögren's syndrome (pSS) is a chronic inflammatory disease primarily affects exocrine glands dysfunction. Oxidative stress (OS) is a phenomenon occurring as a result of an imbalance between the generation of free radicals and antioxidant defense system. Hence, we aimed to establish the status of OS and inflammatory response according to the pSS disease activity index.

Metabolic disorders induced the changes in the expressions of TNFα, E-cadherin and ultrastructural alteration of liver cells in a typical animal model of type 2 diabetes: Psammomys obesus.

By using a unique animal model of type 2 diabetes mellitus, Psammomys obesus induced by a high-calorie diet (HCD) for nine months, we showed for the first time, in the liver, the impact of inflammation on the remodeling of intercellular junction molecules E-cadherins during the progression of steatohepatitis. Under the effect of HCD, the expressions of immunohistochemical markers, Tumor Necrosis Factor alpha (TNFα) and E-cadherins were inversely correlated. Ultrastructural examination revealed the involvement of destabilization and loss of E-cadherins in the process of hepatic pathogenesis.
