The most common preparation of tocotrienols is the tocotrienol-rich fraction (TRF). This study aimed to investigate whether TRF induced liver Nrf2 nuclear translocation and influenced the expression of Nrf2-regulated genes. Methods: In the Nrf2 induction study, mice were divided into control, 2000 mg/kg TRF and diethyl maleate treated groups. After acute treatment, mice were sacrificed at specific time points. Liver nuclear extracts were prepared and Nrf2 nuclear translocation was detected through Western blotting. To determine the effect of increasing doses of TRF on the extent of liver nuclear Nrf2 translocation and its implication on the expression levels of several Nrf2-regulated genes, mice were divided into 5 groups (control, 200, 500 and 1000 mg/kg TRF, and butylated hydroxyanisole-treated groups). After 14 days, mice were sacrificed and liver RNA extracted for qPCR assay. Results: 2000 mg/kg TRF administration initiated Nrf2 nuclear translocation within 30 min, reached maximum level around 1 h and dropped to half-maximal levels by 24 h. Incremental doses of TRF resulted in dose-dependent increases in liver Nrf2 nuclear levels, along with concomitant dose-dependent increases in the expressions of Nrf2-regulated genes. Conclusion: TRF activated the liver Nrf2 pathway resulting in increased expression of Nrf2-regulated cytoprotective genes.

Background and Objectives: Compliance of community pharmacies with the proper practice of storage and dispensing of medicines is crucial for ensuring the quality and safety of medicines, particularly with the circumstance of recurrent electricity blackout in Libya. This study was aimed to assess the compliance of community pharmacies with the proper practice of drug storage in Tripoli city, Libya. Materials and Methods: A cross-sectional survey conducted in November 2020 targeting a total of 56 community pharmacies in Tripoli, Libya. The questionnaire was adapted from the WHO Checklist for Good Storage Practices and included 41 questions organized under five sections: socio-demographics, pharmacist’s attitude toward the quality of storage practices, queries on environmental storage conditions, the quality of facilities in the community pharmacy, and queries on storage and pharmacy practices. Data were presented as descriptive statistics. Results: Out of the total 56 visited pharmacies, a total of 46 (82.1%) pharmacists participated in the study with one pharmacist being interviewed in every pharmacy. Results showed that 15% of employees reported variety of cleanliness regulatory depending on cutting off running water circumstances in Tripoli and other reasons. About 78.8% participants observed dust in shelves and over the drugs packaging, and 22% of the participant pharmacies’ drugs exposure to direct sunlight. Additionally, 72% of employee experienced high temperatures in the pharmacy during electricity blackouts, whereas only 48% of them experienced humidity. In addition, 91.4% had alternative source of electricity, 44.3% had a power backup connected to the refrigerators. Conclusion: The compliance of majority of the community pharmacies operated in Tripoli is below standard. There is still need to improve the storage practices in the community pharmacies by obeying with the regulatory standards as specified by the Drug Regulatory Authority of Libya.

Background: Libya has been malaria-free since 1973. The risk of malaria re-introduction to Libya is increasing because of the increase in imported malaria cases due to immigration to Libya from countries where malaria is endemic. Cases are mainly due to P. falciparum and Sub-Saharan Africa is the most common origin. This study was conducted to investigate the prevalence of malaria positive cases among illegal immigrants in the southern region of Libya. Methods: A prospective, observational, multi-center study was conducted. Three hundred and three illegal immigrants from 12 different countries were included. Enzyme-linked immunosorbent assay was used to detect the presence of serum malaria antibodies. Results: A total of 303 immigrants were included in the study with mean age of 25.78±5.92 years. Of them, 195 tested positive for malaria antibodies. Two hundred and sixty nine of the participants came from Brak Al-Shati, 16 from Sebha and 18 from Bergan centers, with 175, 15 and 5 positive cases, respectively. Most of the positive cases (172) arrived in Libya within 1-10 months. The highest number of positive cases (70) came from Ghana followed by (40) from Niger and (39) from Bangladesh. Conclusions: Illegal immigration is a major malaria re-introduction route. The issue of illegal immigration have to be treated urgently to stop the huge influx of illegal immigrants and increase the surveillance activities of infectious diseases in order to keep Libyan territories as a malaria-free lands. Key words: Illegal immigration, Malaria, Libya.
