Development of New Biosorbent Based on Crosslinked Chitosan Beads with High Brilliant Blue FCF Removal Efficiency.

Effluents containing synthetic anionic dyes can pose a risk to ecosystems, and they must be treated before their release to the environment. Biosorption, a simple and effective process, may be a promising solution for treating these effluents. In this work, chitosan beads were crosslinked with epichlorohydrin to produce a highly stable and performant biosorbent to remove Brilliant Blue FCF dye.

Relationship Between Blood Groups and Cardiovascular Diseases: Insights From an Algerian Inpatient Study.

Introduction:  Research on the association between blood groups and cardiovascular diseases (CVDs) in Africa, including Algeria, is notably limited, with a primary focus on blood donors. This narrow scope hinders a comprehensive understanding of the genetic diversity of blood groups and their potential links to CVD risk within the African context. To bridge this knowledge gap, this study proposes to investigate the distribution of blood group genotypes and their association with CVD prevalence, aiming to enhance knowledge within the African context and contribute to global insights into the relationship between blood groups and CVD.

Increase maximum economic yield in a patchy environment.

In this work, we study the model of a fish species growing logistically exploited by a fishing fleet in a heterogeneous environment. The environment is made up of a network of fishing patches connected by fish migrations taking place on a fast time scale. We are interested in the maximum economic yield (MEY) which corresponds to the maximum profit made by the fishing fleet.

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.

Oral squamous cell carcinoma (OSCC) is a disabling tumor with poor response to chemotherapy. 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. To this purpose, a detailed geometric Monte Carlo (MC) modeling of the LINAC, combined with a hybrid whole-body phantom was carried out. The secondary radiation doses were calculated in patient's organs, both within and outside the field.

Improving water barrier properties of starch based bioplastics by lignocellulosic biomass addition: Synthesis, characterization and antibacterial properties.

Global population growth has led to an increase in the demand for polymers, along with concerns about environmental pollution caused by solid polymers (such as consumer plastics), as well as the threat of global warming resulting from the production of polymer feedstock. Therefore, the polymer industry must develop sustainable and innovative strategies. The present study focuses on testing the potential of corn starch (CS) to produce bioplastic films and the impact of olive pits powder (OPP) addition, a natural agricultural waste material mainly containing lignocellulose, as filler on their properties.

Thermophysical Study of 1-Butyl-2-methylpyridinium bis(trifluoromethylsulfonyl)imide and 1-Butyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide.

Ionic liquids are of great interest for scientists and chemical industries owing to their fascinating properties and their versatile applications. Herein, we focus on the thermophysical properties of two isomeric pyridinium-based ionic liquids: 1-butyl-2-methylpyridinium bis(trifluoromethylsulfonyl)imide and 1-butyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide. Experimental investigation of the liquids involved the measurement of their thermodynamic and transport properties, namely, density, speed of sound, refractive index, surface tension, isobaric molar heat capacity, kinematic viscosity, and electrical conductivity.

Molecular characterization of Staphylococcus aureus from nasal samples of healthy pet cats.

The objective of this study was to characterize Staphylococcus aureus isolates recovered from the nasal samples of healthy pet cats in Algiers province. A total of 138 nasal swabs were collected. Antimicrobial susceptibility was conducted using the disk-diffusion method and the VITEK-2 susceptibility system.

Involvement of inflammasomes in the pathogenesis of Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative disease with a long preclinical and prodromal stage near 20 years. The neuropathological hallmarks of AD include amyloid plaques, neurofibrillary tangles, and neuroinflammation, those lead to neuronal and synaptic loss. Important fact, oxidative stress participates in the AD development by promoting amyloid-β deposition, tau hyperphosphorylation.

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.

Phenotypic and molecular characterization of vancomycin resistant enterococci from wild birds: first detection of a plasmid-borne vanC1 in Enterococcus faecalis.

Vancomycin-resistant enterococci (VRE) are a public health concern as they lead to therapeutic impasses and play a pivotal role in the dissemination of vancomycin resistance genes. As recent evidence suggests that wildlife can play a role in the dissemination of bacterial resistomes, this study explored the potential role of Algerian wild birds as a reservoir of VRE. A total of 222 cloacal and fecal samples were collected from various wild bird species and screened for VRE using a selective medium.

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.
