Arylamine N-acetyltransferase 2 genotype-dependent N-acetylation of isoniazid in cryopreserved human hepatocytes

引用

Acta Pharmaceutica Sinica B 2017年第4期7卷 517-522页

作者： Mark A.Doll raúl A.Salazar-González Srineil Bodduluri David W.Hein Department of Pharmacology and Toxicology and James Graham Brown Cancer Center University of LouisvilleLouisvilleKY 40202USA

Cryopreserved human hepatocytes were used to investigate the role of arylamine N-acetyltransferase 2 (NAT2; EC 2.***.1.5) polymorphism on the N-acetylation of isoniazid (INH). NAT2 genotype was determined by Taqman allelic discrimination assay and INH N-acetylation was measured by high performance liquid chromatography. INH N-acetylation rates in vitro exhibited a robust and highly significant (Prates in situ were INH concentration- and time-dependent. Following incubation for 24 h with 12.5 or 100 µmol/L INH, acetyl-INH concentrations varied significantly (P = 0.0023 and P = 0.0002) across cryopreserved human hepatocytes samples from rapid, intermediate, and slow acetylators, respectively. The clear association between NAT2 genotype and phenotype supports use of NAT2 genotype to guide INH dosing strategies in the treatment and prevention of tuberculosis.

A study of nonlinear age-structured population models

International Journal of Biomathematics 2016年第6期9卷 211-223页

R. China

This paper presents a novel analysis for the solution of nonlinear age-structured prob- lem which is of extreme importance in biological sciences. The presented model is very useful but quite complicated. Modified variational iteration method （MVIM） coupled with auxiliary parameter is used to cope with the complexity of the model which subse- quently shows better results as compared to some existing results available in literature. Furthermore, an appropriate way is used for the identification of auxiliary parameter by means of residual function. Numerical examples are presented for the analysis of the pro- posed algorithm. Graphical results along with the discussions re-confirm the efficiency of proposed algorithm. The work proposes a new algorithm where He＇s polynomials and an auxiliary parameter are merged with correction functional. The suggested scheme is implemented on nonlinear age-structured population models. Graphs are plotted for the residual function that reflects the accuracy and convergence of the presented algorithm.

Comparative phytochemical analysis of Coffea benghalensis Roxb. Ex Schult, Coffea arabica L. and Coffea liberica Hiern

引用

Asian Pacific Journal of Tropical Medicine 2018年第8期11卷 480-485页

作者： éva Brigitta Patay ágnes Alberti Orsolya Csernák Szilvia Stranczinger Nóra Pap Department of Pharmacognosy Faculty of Pharmacy University of Pécs Department of Pharmacognosy Faculty of Pharmacy Semmelweis University Department of Plant Biology Faculty of Sciences University of Pécs

Objective: To make phytochemical studies of the leaf, pericarp and seed of Coffea benghalensis(C. Benghalensis) compared with those of the widely known Coffea arabica and Coffea liberica. Methods: The sample extracts were prepared by Soxhlet-extraction. Polyphenol content was analyzed by HPLC-ESI-MS/MS, the identification was carried out based on the retention time, UV and mass spectra of standards and literature data of the detected compounds. Results: Phenolic acids like caffeoylquinic acids, dicaffeoylquinic acids, feruloylquinic acids and coumaroylquinic acid, as well as mangiferin were detected as main constituents in all extracts. Procyanidin trimers were present exclusively in the leaves. In C. benghalensis, main constituents were 5-caffeoylquinic acid and 4-caffeoylquinic acid. Flavan-3-ols were described in all immature and mature pericarp and leaf extracts. Even though 4-feruloylquinic acid was described in both immature and mature seed, dicaffeoylquinic acids were identified only in the mature seed extracts. Mangiferin was present in the leaf, mature pericarp and seed. Conclusions: These analyses provide new chemotaxonomical data for the selected coffees, especially for C. benghalensis. Due to its high polyphenol content, our results indicate its significance of providing new data as a possible source for industry.

Enhanced recovery pathways in pancreatic surgery: State of the art

引用

World Journal of Gastroenterology 2016年第28期22卷 6456-6468页

Pancreatic surgery is being offered to an increasing number of patients every year. Although postoperative outcomes have significantly improved in the last decades, even in high-volume centers patients still experience significant postoperative morbidity and full recovery after surgery takes longer than we think. In recent years, enhanced recovery pathways incorporating a large number of evidence-based perioperative interventions have proved to be beneficial i n t e r m s o f i m p rove d p o s t o p e ra t i ve o u t c o m e s, and accelerated patient recovery in the context of gastrointestinal, genitourinary and orthopedic surgery. The role of these pathways for pancreatic surgery is still unclear as high-quality randomized controlled trials are lacking. To date, non-randomized studies have shown that care pathways for pancreaticoduodenectomy and distal pancreatectomy are safe with no difference in postoperative morbidity, leading to early discharge and no increase in hospital readmissions. Hospital costs are reduced due to better organization of care and resource utilization. However, further research is needed to clarify the effect of enhanced recovery pathways on patient recovery and post-discharge outcomes following pancreatic resection. Future studies should be prospective and follow recent recommendations for the design and reporting of enhanced recovery pathways.
