| 1 | Association of Fas/Apo1 gene promoter (-670 A/G) polymorphism in Tunisian patients with IBD显示文摘AIM: To detect a possible association between the polymorphism of the (-670 A/G) Fas/Apo1 gene promoter and susceptibility to Crohn's disease (CD) and ulcerative colitis (UC) in the Tunisian population. METHODS: The (-670 A/G) Fas polymorphism was analyzed in 105 patients with CD, 59 patients with UC, and 100 controls using the polymerase chain reaction restriction fragment length polymorphism method. RESULTS: Significantly lower frequencies of the Fas -670 A allele and A/A homozygous individuals were observed in CD and UC patients when compared with controls. Analysis of (-670 A/G) Fas polymorphism with respect to sex in CD and UC showed a significant difference in A/A genotypes between female patients and controls (P corrected = 0.004 in CD patients and P corrected = 0.02 in UC patients, respectively). Analysis also showed a statistically significant association between genotype AA of the (-670 A/G) polymorphism and the ileum localization of the lesions (P corrected = 0.048) and between genotype GG and the colon localization (Pcorrected = 0.009). The analysis ofinflammatory bowel disease patients according to clinical behavior revealed no difference. CONCLUSION: Fas-670 polymorphism was associated with the development of CD and UC in the Tunisian population. | Walid Ben Aleya Imen Sfar Leila Mouelhi Houda Aouadi Mouna Makhlouf Salwa Ayed-Jendoubi Samira Matri Azza Filali Taoufik Najjar Taeib Ben Abdallah Khaled Ayed Yousr Gorgi | 2009 | World Journal of Gastroenterology2009，15，29： | 3 |
| 2 | Formulation, stability testing, and analytical characterization of melatonin-based preparation for clinical trial显示文摘A new institutional clinical trial assessed the improvement of sleep disorders in 40 children with autism treated by immediate-release melatonin formulation in different regimens(0.5 mg, 2 mg, and 6 mg daily) for one month. The objectives of present study were to(i) prepare low-dose melatonin hard capsules for pediatric use controlled by two complementary methods and(ii) carry out a stability study in order to determine a use-bydate. Validation of preparation process was claimed as ascertained by mass uniformity of hard capsules.Multicomponent analysis by attenuated total reflectance Fourier transformed infrared(ATR-FTIR) of melatonin/microcrystalline cellulose mixture allowed to identify and quantify relative content of active pharmaceutical ingredients and excipients. Absolute melatonin content analysis by high performance liquid chromatography in 0.5 mg and 6 mg melatonin capsules was 93.6% ± 4.1% and 98.7% ± 6.9% of theoretical value, respectively. Forced degradation study showed a good separation of melatonin and its degradation products. The capability of the method was 15, confirming a risk of false negative < 0.01%. Stability test and dissolution test were compliant over 18 months of storage with European Pharmacopoeia. Preparation of melatonin hard capsules was completed manually and melatonin in hard capsules was stable for 18 months, in spite of low doses of active ingredient. ATR-FTIR offers a real alternative to HPLC for quality control of highdose melatonin hard capsules before the release of clinical batches. | Samira Filali Charlotte Bergamelli Mamadou Lamine Tall Damien Salmon Diane Laleye Carole Dhelens Elhadji Diouf Christine Pivot Fabrice Pirot | 2017 | Journal of Pharmaceutical Analysis2017，7，4： | 1 |

| 4 | Production and stability study of a hospital parenteral nutrition solution for neonates显示文摘Standard parenteral nutrition solutions are mixtures comprising interacting components that may degrade themselves over time. The objective of this study was to investigate the physicochemical and microbiological stability of a hospital preparation for parenteral nutrition in neonatology. The analyses were performed throughout the storage of the preparations at 2–8 °C(up to 4 months). The extent of stability was based on the determination of amino acids dosage, visual and physicochemical properties(glucose and electrolytes concentrations, pH and osmolality measurements, particle counting) and microbiological analysis(sterility test). A thermal degradation of ascorbic acid was conducted to evaluate the antioxidant properties of the parenteral mixture. Physicochemical and microbiological controls were found to comply with the specifications. Amino acids showed a good stability throughout the 4 months storage except for cysteine, which was progressively degraded to cystine, conferring a yellow coloration to parenteral solutions. Parenteral nutrition standards solutions remain stable for 4 months at 2–8 °C,ensuring safe administration in preterm infants. | Anne-Laure Yailian Céline Serre Justine Fayard Marina Faucon Patrick Thomaré Samira Filali Christine Pivot Florence Vételé Fabrice Pirot Emmanuelle Olivier | 2019 | Journal of Pharmaceutical Analysis2019，9，2： | 0 |
