Lower Bashkirian fusulinoideans from the upper part of the Tagnana Formation (Carboniferous, NW Algeria)
2021
The upper member of the Tagnana Formation of the Djebel Bechar Group (informally the Tagnana-3 or Tagnana Ill member) yielded fusulinoideans and other related foraminifera of the genera Pseudoendothyra (rare), Pseudostajfella (Semistaffella) (rare), Millerella, Pseudonovel/a, Plectostaffella, Eostaffella and Mediocris. The presence of Eostaffellina (rare) and Endostaffella is doubtful. The difference between Millerella and Eostaffella cannot be adequately defined by evolute versus involute coiling. Pseudonovella Kireeva, 1949 is redefined to include Seminovella Rauzer-Chernousova, 1951. The foraminifera are from two samples, one from close to the top and the other from near the base of the …
Essential oils from three Algerian medicinal plants (Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides) as new botanical insectici…
2020
Medicinal and aromatic plants represent an outstanding source of green active ingredients for a broad range of real-world applications. In the present study, we investigated the insecticidal potential of the essential oils obtained from three medicinal and aromatic plants of economic importance in Algeria, Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides. Gas chromatography coupled with mass spectrometry (GC-MS) was used to study the essential oil chemical compositions. The three essential oils were tested against a mosquito vectoring filariasis and arboviruses, i.e., Culex quinquefasciatus, a fly pest acting also as pathogens vector, Musca domestica, and an agricultural…

Euphorbia honey and garlic: Biological activity and burn wound recovery
2019
Currently, chronic wounds and microbial resistance to antibiotics have led to search new healing agents. Combinations of natural products are widely practiced in traditional medicine and exhibited synergistic activity with increased efficacy in treating several pathologies. This study assays the antioxidant, synergistic antimicrobial and burn wound healing activities of Euphorbia honey and Allium sativum (garlic). The minimal inhibitory concentration (MIC) of each natural product was determined against microorganisms commonly found in wound infections. The synergistic antimicrobial effect was assessed by mixing different concentrations of honey and garlic extract below their relative MICs. …
Long-term use of angiotensin II receptor antagonists and calcium-channel antagonists in Algerian hypertensive patients: Effects on metabolic and oxid…
2015
The effects of calcium antagonists (amlodipine) and angiotensin II receptor antagonists (telmisartan) on lipid profile and oxidative markers were investigated in Algerian hypertensive patients. At the beginning and after 1 year of antihypertensive therapy, blood samples are collected for determination of biochemical parameters (glucose, cholesterol, triglycerides, urea, creatinine) and oxidative markers (malondialdehyde, carbonyl proteins, nitric oxide, superoxide anion, vitamin C, glutathione, catalase, superoxide dismutase). The results of this study indicate that telmisartan and amlodipine are effective antihypertensive agents in the treatment of hypertension because a significant reduct…
Circulating mir-21 and mir-146a are associated with increased cytokines and CD36 in Algerian obese male participants
2020
The microRNAs have come up as crucial mediators of energy balance and metabolic control. CD36 is potential biomarker of obesity and metabolic syndrome. This study investigates the concentration of miR-146a and miR-21 and CD 36 in blood samples of obese and healthy young participants. We assessed the association of mir-146a and mir-21 with inflammatory states in Algerian young participants.Our study included male obese, without co-morbidities (miR-146a and miR-21 concentrations were significantly decreased; however, CD36 expression was increased in obese subjects. Interestingly, miR-146a and miR-21 concentrations were negatively correlated to IL-6, TNF-α, and CD36 in obese participants.We de…
Panton-Valentine leukocidin positive sequence type 80 methicillin-resistant Staphylococcus aureus carrying a staphylococcal cassette chromosome mec t…
2012
Methicillin-resistant Staphylococcus aureus (MRSA) is a major antimicrobial drug-resistant pathogen causing serious infections. It was first detected in healthcare settings, but in recent years it has also become disseminated in the community. Children and young adults are most susceptible to infection by community-acquired (CA) MRSA strains. In this study 25 MRSA isolates implicated in infections of neonates and children admitted to an Algiers hospital during an 18 month period were characterized by molecular methods including staphylococcal cassette chromosome (SCC) mec typing, PCR amplification of pvl genes, pulsed field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). F…
Descriptive epidemiology of nasal carriage of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus among patients admitted to two he…
2014
Aim: To evaluate nasal carriage rate and variables associated with Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) in patients admitted in two healthcare facilities. Results: S. aureus was isolated from 159 (26%) of the enrolled patients. Methicillin-susceptible S. aureus was isolated from 150 (24.5%) patients, and MRSA was isolated from 9 (1.5%). Cancer and previous hospitalization were associated with a significantly higher frequency of nasal S. aureus carriage among the patients admitted to the general hospital and the nephrology department, respectively. MRSA isolates were heterogeneous with respect to their staphylococcal cassette chromosome mec element (SC…
Urban dynamics, mobilities and transport in the Algerian Southwest (wilayas of Adrar and Bechar)
2012
Between a regional perspective of the territorial (spatial) planning and a geopolitical vision of the region " Sahel, the Maghreb ", the Algerian State made a commitment since the second decade of its independence not only to develop transport in the Saharan zones but also to set up the necessary equipments for the economical and social development of these zones, by serving almost the totality of the urban areas. In the Southwest, this dynamics remodelled profoundly the relational space in Saoura, Gourara and Touat.Structured formerly by the roads of the trans-Saharan caravan business, this space opens up, attributes new functions and becomes urbanized. A new reorganization of the space is…
The Evolution of the Emancipation Movement of Women in the Maghreb
2019
Regaining independence by each country (Tunisia, Morocco 1956, Algeria 1962) and the publication of relevant documents (codes of family law, constitutions) created opportunities to speak more widely about social and economic rights, or about political rights for women. However, the rights granted to women were characterized by the principle of inequality, especially in Algeria and Morocco. In this difficult and complex situation, the emancipation movement of women went through various phases. In Algeria, its strength began to appear at the turn of the seventies and eighties of the twentieth century and has been constantly increased. In Morocco, in principle, the awakening took place in the …
