Abstract
Background: Lately, several studies have utilized non-invasive serological markers to assess liver fibrosis and some are currently being validated as potential tools to determine liver damage. Purpose: Our aim was to investigate the diagnostic performance of AFP, autotoxin and collagen IV as non-invasive biomarkers of hepatic fibrosis. Patients and methods: 45 males and 15 females with chronic hepatitis C were enrolled in the current study. Laboratory assessment was done for all subjects in form of complete blood picture, liver function test, alpha fetoprotein (AFP), collagen IV and autotaxin. Patients were grouped according to the stage of fibrosis into F1, F2 and F3. Results: Mean serum values of AFP, autotaxin and collagen IV were elevated in all patients compared to healthy controls. Surprisingly, with increasing fibrosis stage AFP showed non-significant change while collagen IV and autotoxin showed significant increase (P<0.01 and P<0.0001, respectively). Autotaxin and collagen IV were significantly (P<0.01 and P<0.05, respectively) lower in F1 patients than those with F2-F3 but AFP level showed non-significant change. Autotaxin had the highest area under ROC curve and the highest accuracy for discrimination of F1 from F2-F3 patients and for discrimination of patients with F3 from F1-F2. Different combinations between AFP, collagen IV and autotoxin showed improvement in the accuracy. Conclusion: It was concluded that serum autotaxin may at least serve as a new clinical non-invasive alternative in patients who are not candidates for liver biopsy for diagnosis of liver damage. Autotaxin combination with collagen IV and AFP addition make them more useful.

Abstract
The present work is to identify the Chemical Composition of methanolic extract from
Cucumis dipsaceus Ehrenb. (Fruit) by using HPLC-UV-ESI-MS Methods. It is very proficient method with amalgamation of liquid chromatography attached to electrospray ionization mass spectrometry in tendem means with positive and negative ion recognition. This is a simple and rapid method for characterization of flavonoid glycosides by using Reversed Phase High Performance Liquid Chromatography coupled to Electrospray Ionization Quadropole Time – of – Flight Mass Spectrometry (RP-HPLC-ESI-Q-TOF-MS). The correctness of mass information generated by Q-TOF-MS jointly with the fragmentation blueprint of the complete scan sprint of MS/MS investigation has been a valuable tool to cautiously characterization of 12 flavonoid glycosides (Molecular weight: 497.04 (RT:3.586), 475.06 (RT:6.801), 393.48 (RT:12.594), 336.50 (RT:16.473), 723.00 (RT:17.774), 452.52(RT:18.253), 978.95 (RT: 25.665), 836.20 (RT: 26.889), 893.00 (RT: 27.925), 838.32 (RT: 31.592), 507.44 (RT: 31.592), 415.18, (RT:33.849) in the methanol extract of this fruit. All these flavonoid glycosides are the first time reported from fruit of

Anto Cordelia T A D, Hng Huey Ping
Abstract
The current study employs green synthesis to acquire silver nanoparticles (AgNPs) using
Artemisia argyi and appraise their antioxidant and antimicrobial potentials. AgNPs were synthesized using aqueous leaf extract of
Artemisia argyi by sunlight irradiation. They were characterized using UV-visible spectrophotometer, FESEM, FTIR and XRD. The antioxidant capacity of AgNPs were evaluated using ABTS, DPPH, iron chelation, FRAP and NO radical scavenging methods. Antimicrobial activities of AgNPs were tested against
Esherichia coli and
Staphylococcus aureus using disc diffusion method. Descriptive statistical analysis was used to identify significant relationship between antioxidant activities of AgNPs. The synthesized AgNPs exhibited brown color light scattering and absorbed maximum wavelength of light at 450 nm. The synthesis of AgNPs was optimum at 0.01 M AgNO
3. The green synthesized AgNPs were spherical in shape with size ranging from 16 nm to 32 nm. The FTIR analysis revealed the presence of proteins, phenolic and polar nitrile compounds in the AgNPs. The purified AgNPs possessed a face centered cubic structure with coexistence of silver chloride crystals. The total phenolic and flavonoid of AgNPs were found to be 77.45 mg GAE/g AgNPs and 205.29 mg GAE/g AgNPs respectively. The radical scavenging activity (EC
50) showed highest activity for NO (31.33 µg/ml) followed by ABTS (128.82 µg/ml), DPPH (263.03 µg/ml) and Fe
2+ (1445.44 µg/ml) with a FRAP value of 1.22 mmol Fe2+ /mg dry weight. AgNPs possessed inhibitory effect against both strains of bacteria in concentration dependent manner. This study discovered that green synthesized AgNPs using
Artemisia argyi are promising sources of effective antioxidants and antimicrobial agents with a high surface area catalytic activity.

D Raghavendra, R K Chauhan, T D mallikarjuna
Abstract
Quality culture implementation in pharmaceutical firm increasingly face challenges to ensuring that patients are provided with medications that are safe, effective and produced at a high level of quality. Despite recent advances in the manufacturing sector quality issues remain frequent occurrence and can result in recalls, withdrawals or harm to patients. A number of strategies have been utilized in various pharmaceutical firms to ensure quality culture for high quality drug products. However, a synthesis of the literature on these strategies has not previously been undertaken. Methods: We reviewed articles published in following websites that assessed and studied interventions for implementing quality culture in pharmaceutical companies and other i.e. non-pharmaceuticals companies. We organized the intervention in each study into three groups: Interventions aiming to increase involvement and empower of employees. Interventions aiming to transform management philosophy on quality culture i.e. Doing right and not what is easy in business. Combined employee and management interventions. We summarized the main quantitative outcomes from each study and effective practices from each intervention category. Results: Ten studies were identified; one described interventions designed to improve employee’s perspective and engagement towards quality culture, one described interventions that aimed to increase management involvement day-to-day quality culture and eight studies aiming to improve both availability of employees and management participation and engagement in quality culture roll-out and implementation. All studies reported positive change. Conclusions: Few studies have assessed interventions designed explicitly for the unique challenges facing quality culture roll-out in pharmaceutical firms. Further research on sustainability, scalability and cost effectiveness of interventions is needed to fill this gap.
