Removal of crystal violet dye using a three-dimensional network of date pits powder/sodium alginate hydrogel beads: Experimental optimization and DFT calculation.

Biodegradable and very low-cost adsorbent beads were prepared from date pits powder (DP) and sodium alginate (SA). DP to SA ratios was varied (1/2, 1/4 and 1/6) and used to eliminate Crystal violet (CV) a cationic dye. Adsorbents were characterized by FTIR, SEM-EDS, UV-vis DR, TGA and the point of zero charge (pH).

Impact of the nutritional quality of barley on growth rate, biometric and biochemical parameters and plasma concentration of androgens during puberty in the Ouled-Djellal lambs.

Puberty is part of physiological processes including growth, adrenarche, menarche, energy balance and metabolism. This study describes the dynamic between both metabolic and reproductive statutes during pubertal growth in Saharan breed sheep. Once weaned (3 months age), two lots of lambs are made up and each one receive a barley supplementation ration of 250 vs 500 g/head/day in addition to season's diet.

Complex and CTX-M Extended-Spectrum β-Lactamases in Algeria.

We evaluated the β-lactam resistance phenotypes of clinical and environmental strains of the (ECC) isolated from three Algerian hospitals. The first combination of API 20E, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and hsp60 genetic clustering methodologies were carried out for the identification of ECC strains. Our research showed that API 20E and MALDI TOF MS are satisfactory in genus identification of ECC strains, but sequence-based methods are then necessary to discriminate the species and subspecies levels.

and : Chemical Composition, In Vivo Antiinflammatory, Pain Killing and Antipyretic Activities: A Comprehensive Comparison.

This study aimed to investigate the chemical composition, and evaluate the antioxidant, anti-inflammatory, anti-pyretic, and the analgesic properties of methanol extracts from the leaves of (Lamiaceae). Thirty-five secondary metabolites were characterized in both extracts using HPLC-PDA-ESI-MS/MS. Phenolic acids, mainly rosmarinic acid and its derivatives, dominated the extract, while the phenolic diterpene carnosol and the methylated flavonoid salvigenin, prevailed in extract.

Evolutions in cardiac and gonadal ultra-structure during a "cycle" of androgenic anabolic abuse in adult male mice.

Background: The importance of the present study comes from the lack of sufficient information about the reversibility of the potential histopathological alterations which may result from anabolic androgenic drugs abuse by "Cycling" protocol. So, the aim of this study is to explore the negative effects of Deca-Durabolin abuse in cardiac and gonadal ultra-structures during an administration cycle.

Methods: For our purpose, study was performed on 40 male adult mices.

Abuse of androgenic anabolic drugs with "Cycling" induces hepatic steatosis in adult male mice.

Background: The importance of the present study comes from the lack of sufficient information about the reversibility of the potential hepatic histopathological alterations which may result from anabolic androgenic drugs abuse by "Cycling" protocol. So, the aim of this study is to explore the negative effects of Deca-Durabolin abuse in hepatic function and structure during an administration cycle.

Methods: For our purpose, study was performed on 40 male adult mices.

Reversible effects of anabolic steroid abuse on cyto-architectures of the heart, kidneys and testis in adult male mice.

The importance of the present study comes from the lack of sufficient information about the reversibility of the histopathological alterations which may result from anabolic androgenic drugs abuse after some times of stop treatment, as it is one of the prior studies which explored the negative effects of Deca-Durabolin abuse in particular on the hearts, kidneys and testis structures. For this aim, study was performed on 40 male adult mices. Animals were divided into five groups of 8 animals each as follows: treated by Deca-Durabolin (nandrolone decanoate) at 30 g/kg of BW, weekly during one month (GI); two months (GII); three months (GIII); three months followed by six weeks of treatment discontinuation (GIV) and Control (C).

The eating habits of Patients with Type 2 diabetes in Algeria.

Objective: To evaluate the eating habits and the practice of physical-activity of patients with Tyhpe-2 diabetes. (DT2).

Methods: A total of 1523 patients DT2 with average age 58±9.
