Lipid biochemistry can seem overwhelming, which is why it needs to be explained in a simple and straightforward manner. Ashour Saleh Eljamil, a renowned professor of biochemistry, has written this textbook for undergraduate students in the medical sciences, but its a resource that anyone can use to bolster their knowledge about this important subject. To fully understand biochemistry, you need to know how biomolecules are structured, which is why the first chapter emphasizes the individual chemical structure of various lipid classes. Youll also learn how dietary lipids are digested and absorbed as well as how their metabolism works in separate chapters focusing on fatty acids synthesis, fatty acid oxidation, acylglycerols and sphingolipids, glycolipids, cholesterol, plasma lipoproteins, steroid hormones, and fat-soluble vitamins. While scientists have studied lipid biochemistry for three centuries, its only in the past few decades that weve begun to understand why its so important. Gain a clearer understanding of the world with insights about bile acids, sterols, carotenoids, sex hormones, vitamin K and much, much more when you dive into the world of Lipid Biochemistry. arabic 5 English 35

Abstract Introduction: Extended-spectrum β-lactamases (ESBLs), AmpC type, carbapenem resistant Enterobacteriaceae (CRE), are important mechanisms of resistance among Enterobacteriaceae. The aim of this study was to investigate the prevalence of ESBL, AmpC and CRE among Enterobacteriaceae isolates recovered from pediatric patients in Tripoli, Libya. Methods: This cross-sectional study was carried out in Tripoli Children Hospital (TCH), a total of 915 Gram negative bacteria isolates were evaluated for susceptibility to a panel of antimicrobials and were analyzed phenotypically for the ESBL, AmpC type and CRE using chromagen media, E-test and combination disc test. Results: The predominant organisms were Escherichia coli (56.8%) and Klebsiella spp. (21.4%). The overall prevalence of ESBL producing Enterobacteriaceae was 24.5% (224/915). Out of 224, Enterobacteriaceae proved ESBL producer, Klebsiella spp. (54%) and E. coli (34.4%) were the leading ESBL producers. ESBL-producers were more often resistant to major classes of antibiotics compared with non-ESBL producers, significantly high resistance rates (P < 0.001) were observed for ceftriaxone, cefepime, and ceftazidime (87.5 - 95.9%) among ESBL producers compared to non-ESBL producers (7.2 - 13.5%). MDR was documented for 50/224 (22.3%) of ESBL producers and was significantly higher (P < 0.0001) among ESBLs compared with non-ESBL producer isolates. Phenotypic detection of AmpC revealed 60/915 (6.6%) isolates as potential AmpC β-lactamase producers, E. coli exhibited a lower level of AmpC (8.3%) compared with Klebsiella spp. (56.6%). The overall prevalence of CRE was 9% (83/915). Carbapenemase-producing organisms in this study were as follows: Klebsiella spp. (44.6%); Acinetobacter spp. (24%); Pseudomonas spp. (9.6%). Conclusion: This study revealed that the prevalence of ESBL, AmpC, CRE and MDR Enterobacteriaceae isolates in Children hospital was within acceptable frequency. arabic 11 English 91

Takayasu’s arteritis (TA) is a large‑vessel vasculitis that involves the aorta and its major branches. Renal arteries are frequently involved, usually with renovascular hypertension. The prevalence of TA in Arabs is low. A study of the epidemiological and clinical features of TA in Arabs included 197 identified patients between 1995 and 2012 and none of them was Libyan. We report a 61‑year‑old Libyan woman in whom TA manifested with hypokalemia and arterial hypertension. Previous ultrasound showed renal size asymmetry raised the possibility of renal artery stenosis. The diagnosis of TA was confirmed by magnetic resonance angiography, which showed a thickened abdominal aortic wall, occlusions of the left renal artery and left common iliac artery, stenosis of the right common iliac artery, and stenosis of both subclavian arteries. TA is rarely encountered in Arabs. However, the disease must be considered in patients who present with renovascular hypertension, in a context of other autoimmune disorders. arabic 6 English 33
