Libya’da Okula Başlayan Çocuklarda Boğmaca Seroprevalansı, Kesitsel Bir Çalışma

Bulgular: 791 çocuktan (421 erkek, 370 kız, ortalama yaş 6.5) alınan örnekler test edildi. Tüm çocuklar hayatlarının ilk iki yılında 4 doz tam hücreli boğmaca aşısı ile aşılanmıştı. Yakın zamanda gerçekleşen ve gerçekleşmeyen boğmaca enfeksiyonu sıklığı sırasıyla% 4.8 ve% 2.5 idi. Çocukların% 76.1’i tespit edilemeyecek düzeyde IgG’ye sahipti. Sonuç: Çalışma boğmaca enfeksiyonun okula başlayan çocuklar arasında sık olarak geçirildiğini göstermiştir. Bu artış, okula başlama yaşındaki çocukların% 76.1’inde serumda boğmacaya karşı antikor düzeyinin tespit edilemeyecek düzeyde olmasının dolaylı bir sonucu olması ile açıklanmıştır. arabic 26 English 62

Seroprevalence of Measles, Mumps, and Rubella Antibodies in Libyan Children at School Entry Evaluation of MMR Immunization Program

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

A comparative study of alkaline phosphatase level in serum of patients with end-stage renal disease, viral hepatitis (C) and (B)

Alkaline phosphatase (ALP) enzyme level, which is routinely measured at clinical laboratories, increases in end-stage renal disease (ESRD) and hepatitis patients. This study investigated the difference in ALP level among ESRD and hepatitis patients. ALP level was measured in sera of patients suffering from ESRD, HCV and HBV infections, as well as patients suffering from comorbidity of these diseases, then the obtained values of ALP level were statistically compared to a control group. The results of three-Way ANOVA revealed that the mean of ALP level increased significantly (P-value< 0.05) in all types of diseases compared to the control group, with the highest increase in case of ESRD patients infected with Hepatitis B and C. Also, it was found that the interaction of group-gender significantly (P-value< 0.05) altered ALP level in patients suffering from HCV or HBV infections, while the interaction of group-age, gender-age, group-gender-age were found not to significantly alter it. In conclusion, ESRD patients with HBV/HCV coinfection may have a higher risk of liver-related morbidity and mortality than ESRD or HBV or HCV patients. arabic 25 English 103

Association of venous thromboembolism and myocardial infarction with Factor V Leiden and Factor II gene mutations among Libyan patients

Factor V Leiden G1691A (FVL) and Factor II prothrombin G20210A (PGM) mutations are the leading causes of thrombophilia. In this study, we have investigated the prevalence of the FVL G1691A and PGM G20210A single nucleotide polymorphisms (SNPs) among Libyan deep vein thrombosis (DVT) and myocardial infarction (MI) patients. SNP genotyping was performed using high-resolution melt analysis (HRM) and DNA sequencing. Biochemical parameters conducted on 112 males and 93 females showed no significant difference in means between the control group and the deep vein thrombosis and myocardial infarction groups. For Factor V Leiden, 40 samples were genotyped. Of the 40 samples, 6 (15.0%) of them were heterozygous and no one was homozygous. As for Factor II SNP, 59 samples were genotyped and only 2 (3.3%) were heterozygous. All the heterozygous samples showed 100% concordance between the HRM-PCR and DNA sequence analysis. Our study showed, for the first time, that both the FVL and PGM mutations are present among Libyan DVT and MI patients and that the FVL mutation is significantly associated with DVT but not with MI. However, our results do not support the association of PGM G20210A mutation with DVT or MI. arabic 18 English 117

Anti-angiogenic and anti-inflammatory activity of the summer truffle (Tuber aestivum Vittad.) extracts and a correlation with the chemical constituents identified therein

Fungi are a huge source of unexplored bioactive compounds. Owing to their biological activities, several fungi have shown commercial application in the health industry. Tuber aestivum Vittad. is one such edible fungi with an immense scope for practical biological applications. In the present study, the anti-angiogenic activity of petroleum ether and ethanol extracts of T. aestivum was investigated using the chick chorioallantoic membrane assay and compared to the positive controls silibinin and lenalidomide. Both the extracts showed a dose-dependent anti-angiogenic response. The extracts were also assessed for their anti-inflammatory potential by lipoxygenase-inhibition assay. The IC50 values for LOX inhibition assay, computed by the Boltzmann plot, were 368.5, 147.3 and 40.2 μg/mL, for the petroleum ether extract, ethanol extract, and the positive control ascorbic acid, respectively. The ethanol extract of T. aestivum showed superior anti-angiogenic and anti-inflammatory activity than the petroleum ether extract. Compositional investigation of the extracts by GC–MS revealed the presence of various bioactive compounds. The compounds were correlated to their anti-angiogenic and antiinflammatory activity based on a meticulous literature search. arabic 25 English 145

Anti-Angiogenic Effect of Cantharellus cibarius Extracts, its Correlation with Lipoxygenase Inhibition, and Role of the Bioactives Therein

Angiogenesis is a complex physiological process that cannot be treated with single agent therapy. Several edible fungi have been known to encompass bioactive compounds, and are promising sources of multi-component drugs. One such widely consumed edible fungi is Cantharellus cibarius, which has been explored for its biological activities. The present study focused on assessing the anti-angiogenic activity of petroleum ether and ethanol extracts of C. cibarius using chick chorioallantoic membrane (CAM) assay. Both the extracts showed a dose-dependent response which was compared with the anti-angiogenic activity of the positive controls silibinin, and lenalidomide. The extracts were also studied for their lipoxygenase (LOX) inhibitory potential and compared to ascorbic acid as the positive control. The IC50 values of the petroleum ether extract, ethanol extract, and ascorbic acid for LOX inhibition assay were 135.4, 113.1, and 41.5 mg/mL, respectively. Although both the extracts showed similar responses in CAM assay, ethanol extract proved to be more potent in LOX inhibition assay. Finally, the extracts were investigated for their chemical composition using GC-MS. A correlation between LOX inhibition and anti-angiogenic potential was established at the molecular level. A meticulous literature search was carried out to correlate the biochemical composition of the extracts to their anti-angiogenic activity arabic 19 English 119
