Assessment of microplastic abundance and impact on recreational beaches along the western Algerian coastline.

Microplastics (MPs) have attracted global attention due to their ubiquity and potential impact on the environment. However, MPs are poorly documented along the Algerian coast. To address this data gap, this study investigated the presence of MPs on three recreational beaches in western Algeria (Stidia, Sablettes and Mersat El Hadjaj).

Leaf-buds of : a novel source of bioactive molecules with high anti-inflammatory, antioxidant, anti-tyrosinase and antimicrobial properties.

In this study, for the first time, the anti-inflammatory antioxidant, anti-tyrosinase and antimicrobial property of subsp leaf-bud extract have been investigated. The anti-inflammatory activity was determined in vivo by reducing carrageenan-induced hind paw edema in mice, while the antiradical function was evaluated using DPPH, total antioxidant capacity (TAC) and reduction power assays. The extract induced a significant reduction of the edema, from 1 to 6 h in a dose-dependent manner (150, 200 and 300 mg/kg).

Predictive Optimization of Electrical Conductivity of Polycarbonate Composites at Different Concentrations of Carbon Nanotubes: A Valorization of Conductive Nanocomposite Theoretical Models.

Polycarbonate-carbon nanotube (PC-CNT) conductive composites containing CNT concentration covering 0.25-4.5 wt.

Anti-Ulcerogenic and Cytoprotective Effects of Saharian (Sidr) Honey from Algeria.

Aim And Objective: This study aimed at investigating the gastro-protective effects of Algerian Sahara (Sidr) honey from Apis mellifera intermissa against HCl/Ethanol-induced gastric ulcers in rats.

Materials And Methods: Total phenolic content, antioxidant activity and phenolic compounds were determined. Then, three groups of rats (control, HCl/ Ethanol-induced ulcer, and orally administered honey) were used for the determination of gastro-protective effect of Sidr honey.

Simulation and Optimization of Electromagnetic Absorption of Polycarbonate/CNT Composites Using Machine Learning.

Electronic devices that transmit, distribute, or utilize electrical energy create electromagnetic interference (EMI) that can lead to malfunctioning and degradation of electronic devices. EMI shielding materials block the unwanted electromagnetic waves from reaching the target material. EMI issues can be solved by using a new family of building blocks constituted of polymer and nanofillers.

Fungal endophytes alleviate salt stress in wheat in terms of growth, ion homeostasis and osmoregulation.

Aims: This study examined the ability of isolated endophytic fungi to confer salt stress tolerance on wheat.

Methods And Results: Tolerance of pot-grown wheat in greenhouse to salt stress was measured by estimating emergence rate, growth, relative water content, photosynthetic pigments biosynthesis, Na and K contents, as well as sugar and proline levels under salt stress in inoculated wheat seedlings. Chaetomium coarctatum (66·7%) and Alternaria chlamydospora (56·7%) improved wheat seedling emergence under moderate salinity (2·5 dS m ) compared to noninoculated plant (50%).

Antimicrobial and anti-inflammatory activities of three halophyte plants from Algeria and detection of some biomolecules by HPLC-DAD.

Antimicrobial activity of hydroalcoholic extracts (30/70) from leaves and stems of three halophytes ( and ) was investigated. toxicological study and anti-inflammatory activity of leaf extract of were tested on carrageenan-induced inflammatory paw edema. possessed significant anti-inflammatory activity at 150 and 300 mg/kg confirmed by histological study of inflamed tissues.

Identification of two new keratinolytic proteases from a Bacillus pumilus strain using protein analysis and gene sequencing.

The Bacillus strain (CCUG 66887) has a high capacity to excrete keratinase with the ability to degrade both alpha- and beta keratin. In this study we aimed to show the characteristics of the keratinolytic protease and to identify its gene by using liquid chromatography-electrospray ionization tandem mass spectrometry methods (nanoHPLC-ESI-MS/MS) followed by Mascot data base search. The results showed that the enzyme in fact consists of two different keratinases, both with a molecular mass of 38 kDa.

In vivo antiinflammatory activity and chemical composition of Hypericum scabroides.

Objective: To evaluate the methanolic extracts of aerial parts of Hypericum scabroides (HSM) (200 mg/kg, p.o.) for in vivo anti-inflammatory activity.

In vitro activity of natural honey alone and in combination with curcuma starch against Rhodotorula mucilaginosa in correlation with bioactive compounds and diastase activity.

Objective: To evaluate the in vitro activity and synergism of the combinations of natural honey and curcuma starch against Rhodotorula mucilaginosa in correlation with total phenolic, flavonoid contents, and diastase activity.

Methods: The Folin-Ciocalteu test was used to determine the total polyphenols content and the flavonoid content was analyzed using by the aluminum chloride method. The antifungal activity of the natural honey, determined by an agar well diffusion assay and agar incorporation method.
