The detection of somatic mutations in tumours is essential for the understanding of cancer development and targeting therapy. The screening for BRAF V600E mutation is employed in clinical practice in Libya for its prognostic and potentially predictive role in patients with metastatic colorectal carcinoma (mCRC). Using of BRAF mutant DNA and wild type DNA targets, we found that the sensitivity of allelic discrimination-Real Time PCR was applicable. The Real Time PCR assay displayed increased analytical sensitivity in detecting the BRAF V600E mutation. The association of BRAF mutations with clinical and pathological features was assessed using Real Time PCR assay. Qiagen Real Time PCR Platform was utilised using a set of primers. forward 5-GAC.

Our study indicates that Real Time PCR-based assays is convenient to detect the BRAF V600E mutation in CRC and that BRAF mutations screening should not be restricted to selected patients on the basis of the clinicalpathological characteristics. arabic 9 English 63

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

Objectives Multidrug resistance (MDR) and emergence of extended-spectrum β-lactamases (ESBLs) among uropathogenic Escherichia coli have been reported worldwide, but there was no information on the detection of blaCTX-M-15 in major teaching hospitals in Libya. The aim of the study was to investigate the occurrence of CTX-M-15 β-lactamases producers isolated from five teaching hospitals in Tripoli, Libya. Methods A total of 346 urine samples were collected from hospitalized patients in five teaching hospitals with a diagnosis of urinary tract infection (UTI). Phenotypic confirmation of ESBLs was confirmed by E-test strip; all ESBL-producing E. coli isolates were screened for the blaCTX-M-15 gene. Results The distribution of ESBL-producing E. coli varied among the five hospitals. The highest proportion was identified in Tripoli Medical Centre (67.6%). There were extremely high proportions of isolates resistant to ceftriaxone, cefepime, and ceftazidime (93.0–100.0%) among ESBL producers compared to non-ESBL producers (2.2–4.7%). MDR was detected in 22.2% of isolates. The majority of isolates (85.9%) in which blaCTX-M-15 was identified were ESBL producers. There was a correlation (p < 0.001) between expression of CTX-M-15 and resistance to ceftazidime. Conclusions The isolation of MDR ESBL-producing uropathogens expressing the CTX-M-15 gene will limit the choices clinicians have to treat their patients with UTIs. Continued surveillance and implementation of efficient infection control measures are required. arabic 17 English 94
