Abstract: Familial hypercholesterolemia (FH) is an autosomal dominant genetic disorder of lipid metabolism, associated with elevated levels of low-density lipoprotein-cholesterol (LDLC), which can lead to premature cardiovascular disease and early death. Early diagnosis and initiation of treatment is important to prevent morbidity and mortality. Autosomal dominant hypercholesterolemia (ADH) is largely due to mutations in the low-density lipoprotein receptor gene (LDLR), the apolipoprotein B-100 gene (APOB), or the proprotein convertase subtilisin/kexin type 9 (PCSK9). In this study, genomic DNA of unrelated Libyan individuals with clinically diagnosed (FH) was analyzed by direct sequencing after dependent specific PCR primers amplification and DNA purification. That led to the identification of PCSK9 gene mutations for the first time in Libyan population which was compare to other populations. All 12 exons of PCSK9 gene and boundaries genotyped polymorphisms were sequenced, including leucine repeats coded in exon 1, by fluorescently tagged markers. We identified an allele for the rs67610340 polymorphism: an in-frame deletion, c.61_63delCTG (L8). We also identified another allele rs67610340 polymorphism: an in frame insertion c.61_63InsCTG (L10). The insertion and deletion alleles were both in exon 1 and could be associated with a risk and severity of coronary artery disease (CAD), suggesting a direct effect of PCSK9 on atherogenesis. arabic 11 English 90

Measles, Mumps ,and rubella (MMR) are serious diseases that can lead potentially to disability and death. The study aimed to determine seroprevalence rates of antibody levels against MMR among Libyan children at school entry. This was a cross sectional study undertaken in Tripoli, from August to September 2016. Children of school-entry age (> 5 to ≤ 7 years) were randomly recruited at vaccination centers. Sera were tested for antibodies againstMMR. Data analyzed by SPSS program version 20. Out of 546 children, 290 were males. IgG antibodies against measles, mumps, and rubella were positive in 513 (94%), 436 (80%), 538 (98.5%) children, respectively. Seropositivity rates in Libyan children at school entry is protective and this is similar in so many other studies. This indicates that MMR vaccine program is effective in strengthening herd immunity in the Libyan community. arabic 19 English 111

Inflammatory bowel disease (IBD) is a general term describing chronic, idiopathic relapsing, inflammatory conditions of the gastrointestinal tract of unknown etiology. Previous studies have indicated that Malva parviflora leaf extract possesses anti-inflammatory, antioxidant, and antiulcerogenic activity. activity. This work aimed to investigatee the anti-inflammatory effect of the methanolic (MEMP) and aqueous (AEMP) extracts of M. parviflora leaves on acetic acid-induced colitis in rats. arabic 19 English 104
