Item Ethnopharmacological survey of medicinal plant knowledge in boumerdes, algeria: traditional usage patterns and therapeutic applications(Taylor &francis, 2025) Oussaid, Sounia; Bouchenak, Ouahibaa; Yahiaoui, Karima; Hafid, Nourehoudaa; Khiari, Ouiza; Khelef, Yahiac; Laoufi, RazikadThis ethnopharmacological survey documents the persistence of traditional plant knowledge in Boumerdes, Algeria. Through systematic interviews with 900 participants, quantitative analysis revealed distinct user profiles: predominantly women (52.1%) aged 50-70 years (39.0%), with inverse correlation to education level. Integration with conventional medicine was reported by 47% of users, motivated by perceived efficacy (41.5%) and safety (35.7%). Botanical inventory identified 263 species across 91 families, dominated by Lamiaceae (22.3%). Primary therapeutic applications targeted digestive (32.3%), respiratory (19.9%), and dermatological (11.5%) disorders. These findings validate the cultural resilience of traditional healthcare practices and underscore the imperative for phytochemical validation of documented species.Item Students’ perceptions regarding the abrupt transition to online learning during the COVID-19 Pandemic: Case of Faculty of Chemistry and Hydrocarbons at the University of Boumerdes—Algeria(American Chemical Society, 2020) Blizak, Meriem Djanette; Blizak, Salah; Bouchenak, Ouahiba; Yahiaoui, KarimaIn recent months, universities around the world have been forced to cancel courses and close their doors due to the growing coronavirus epidemic. Following the government’s precautions, Algerian students were bound to quarantine regulations for their safety. Thus, they unexpectedly switched to online learning instead of face-to-face learning. Our objective of this exploratory study is to investigate the perceptions of Algerian university students regarding the abrupt transition to online learning amid the COVID-19 pandemic. To achieve this goal, an online survey with closed and open-ended questions was conducted among 380 students from the faculty of chemistry and hydrocarbons (FCH) at the University of Boumerdes—Algeria. The results showed that students have a negative perception of online learning. They are reluctant about this new digital pedagogy and prefer the traditional way of teaching to online teaching during the coronavirus pandemicItem MALDI-TOF MS detection of endophytic bacteria associated with great nettle (Urtica dioica L.), grown in Algeria(2018) Toubal, Souheyla; Bouchenak, Ouahiba; Elhaddad, Djillali; Yahiaoui, Karima; Boumaza, SarahAny plant with a vascular system has a specific endophytic microflora. The identification of bacteria is essential in plant pathology. Although identification methods are effective, they are costly and time consuming. The purpose of this work is to isolate and to identify the different bacteria from the internal tissues of Urtica dioica L. and to study their diversity. This last is based on the different parts of the plant (stems, leaves and roots) and the harvest regions (Dellys and Tlamcen). The identification of bacteria is done by biochemical tests and confirmed by MALDI-TOF MS. Seven genus and eleven species were isolated from the Great Nettle. They belong to the genera Bacillus, Escherichia, Pantoea, Enterobacter, Staphylococcus, Enterococcus and Paenibacillus. The majority of these bacteria were isolated from Tlemcen which makes this region the richest in endophytic bacteria compared to that harvested from Dellys. The results show also that the leaves are the most diversified in endophytic bacteria. Bacillus pumilus-ME is the common species of the three parts of the plant harvested in both regions. From this work, it emerges that the Great Nettle can be settled by various endophytic bacteria which are differently distributed within the same plant harvested in different regions
