Fatty Acid and Phenolic Profiles of Virgin Olive Oils from Local and European Varieties Planted in Lebanon.

In Lebanon, olive oil is an integral part of its history and culinary traditions. However, the quality of this product, originating from different growing regions of the country, is rarely addressed. The objectives of this study were to compare the fatty acids and phenolic profiles of virgin olive oils produced from two local and eight European varieties, and to use these profiles as a tool for their characterization. Seventy-six samples were collected from two olive-growing regions of Lebanon and at two harvesting times. Fatty acid composition was determined by gas chromatography with a flame ionization detector, total phenols was determined by spectrophotometry and individual phenols by high performance liquid chromatography with diode array detector. All samples were also analyzed using near infrared spectroscopy. The experimental data were collected in numerical matrices and treated by chemometric methods. The results showed the significant effect of the geographical origin, the olive variety and the harvesting time on the ripening and industrial yield of the olives and on the major fatty acids and phenols of olive oil. Moreover, the used chemometric methods allowed the discrimination of European olive varieties based on their high contents of oleic acid, oleacein and oleocanthal.

Bioexploration and Phylogenetic Placement of Entomopathogenic Fungi of the Genus Beauveria in Soils of Lebanon Cedar Forests.

The cedar forests of Lebanon have been threatened by the outbreak caused by climate change of a web-spinning sawfly, Cephalcia tannourinensis (Hymenoptera: Pamphiliidae), which negatively impacted the survival of one of the oldest tree species on earth. In this study, we investigated the occurrence of naturally soil-inhabiting entomopathogenic fungi for their role in containing the massive outbreak of this insect. We used a combination of fungal bioexploration methods, including insect bait and selective media. Morphological features and multilocus phylogeny-based on Sanger sequencing of the transcripts encoding the translation elongation factor 1-alpha (TEF-α), RNA polymerase II second largest subunit (RBP2), and the nuclear intergenic region (Bloc) were used for species identification. The occurrence rate of entomopathogenic fungi (EPF) varied with location, soil structure, forest structure, and isolation method. From 15 soil samples positive for fungal occurrence, a total of 249 isolates was obtained from all locations using different isolation methods. The phylogenetic analysis confirmed the existence of two novel indigenous species: Beauveria tannourinensis sp. nov. and Beauveria ehdenensis sp. nov. In conclusion, the present survey was successful (1) in optimizing the isolation methods for EPF, (2) investigating the natural occurrence of Beauveria spp. in outbreak areas of C. tannourinensis, and (3) in characterizing the presence of new Beauveria species in Lebanese cedar forest soil.

Symptoms of post-traumatic stress disorder among battered women in Lebanon: an exploratory study.

Intimate partner violence against women is common in Lebanon and can lead to major health problems. However, the incidence of symptoms of post-traumatic stress disorder (PTSD) in battered women has not been extensively explored in the Lebanese cultural context. The objectives of this study were as follows: (a) to determine the prevalence of PTSD symptoms among women in Lebanon who have been physically abused by their partners, (b) to assess whether the rate of PTSD symptoms varied according to sociodemographic variables, and (c) to reveal other attributes that might be risk factors for developing symptoms of PTSD. Of the 95 physically abused women who met inclusion criteria, 85 completed a questionnaire including sociodemographic questions, the physical abuse subscale of the Composite Abuse Scale (CAS), and the PTSD Checklist-Civilian Version (PCL-C). Results showed a high prevalence of PTSD symptoms (97%), positively correlated with physical violence (r = .719). Lower education level and recent abuse were correlated with symptom severity, as were the number of problematic habitual behaviors in the abusive partner and the use of psychotherapy. Increased involvement of health care professionals in the detection of women at risk, with referral to appropriate resources, is suggested to improve prevention and management efforts.
