1Expression of bcI-2 gene family during resection induced liver regeneration:Comparison between hepatectomized and sham groups显示文摘AIM:During liver regeneration cellular proliferation and apoptosis result in tissue remodeling to restore normal hepatic mass and structure.Main regulators of the apoptotic machinery are the Bcl-2 family proteins but their roles are not well defined throughout the liver regeneration.We aimed to analyze the expression levels of bcl-2 gene family members during resection induced liver regeneration.METHODS:We performed semi-quantitative RT-PCR to examine the expression level of bak, bax, bcl-2 and bcl-XL in 70% hepatectomized rat livers during the whole regeneration process and compared to that of the sham and normal groups.RESULTS:The expression of bak and baxwas decreased whereas that of bcl-2 and bcl-XL was increased in hepatectomized animals compared to normal liver at most time points.We also reported for the first time that sham group of animals had statistically significant higher expression of bak and bax than hepatectomized animals.In addition, the area under the curve (AUC) values of these genes was larger in sham groups than the hepatectomized groups.CONCLUSION: The expression changes of bak, bax, bcl-2 and bcl-XL genes are altered not only due to regeneration,but also due to effects of surgical operations.Kamil Can Akcali Aydin Dalgic Ahmet Ucar Khemaeis Ben Haj Dilek Guvenc 2004World Journal of Gastroenterology2004,10,2:13
2In vitro antibacterial and antitumor activities of some medicinal plant extracts, growing in Turkey显示文摘Objective: To investigate antibacterial and antitumor activities of 51 different extracts prepared with 3 types of solvents (water, ethanol and methanol) of 16 different plant species (Ajuga reptans (A. reptans) L., Phlomis pungens (P. pungens) Willd., Marrubium astracanicum (M. astracanicum) Jacq., Nepeta nuda (N. nuda) L., Stachys annua (S. annua) L., Genista lydia (G. lydia) Boiss., Nuphar lutea (N. lutea) L., Nymphaea alba (N. alba) L., Vinca minor (V. minor) L., Stellaria media (S. media) L., Capsella bursa-pastoris (C. bursa-pastoris) L., Galium spurium (G. spurium) L., Onosma heterophyllum (O. heterophyllum) Griseb., Reseda luteola (R. luteola) L., Viburnum lantana (V. lantana) L. and Mercurialis annua (M. annua) L.) grown in Turkey was conducted. Methods: Antibacterial activity was evaluated with 10 bacteria including Streptococcus pyogenes (S. pyogenes), Staphylococcus aureus (S. aureus), Staphylococcus epidermidis (S. epidermidis), Escheria coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), Salmonella typhimurium (S. typhimurium), Serratia marcescens (S. marcescens), Proteus vulgaris (P. vulgaris), Enterobacter cloacae (E. cloacea), and Klebsiella pneumoniae (K. pneumoniae) by using disc diffusion method. Antitumor activity was evaluated with Agrobacterium tumefaciens (A. tumefaciens)-induced potato disc tumor assay. Results: Best antibacterial activity was obtained with ethanolic extract of P. pungens against S. pyogenes . Ethanolic and methanolic extract of N. alba and ethanolic extract of G. lydia also showed strong antibacterial activities. Results indicated that alcoholic extracts especially ethanolic extracts exhibited strong antibacterial activity against both gram-positive and gram-negative bacteria. Best antitumor activity was obtained with methanolic extracts of N. alba and V. lantana (100% tumor inhibition). Ethanolic extract of N. alba , alcoholic extracts of N. lutea , A. reptans and V. minor flowers, methanolic extracts of G. lydia and O. heterophyllum and ethanolic extract of V. lantana and aqueous extract of V. minor leaves exhibited strong tumor inhibitions. Conclusions: In near future works, identification of active components can be studied for plant extracts having strong bioactivity.Arzu Birinci Yildirim Fatma Pehlivan Karakas Arzu Ucar Turker 2013Asian Pacific Journal of Tropical Medicine2013,6,8:6

4Collagen for brain repair:therapeutic perspectives显示文摘Biomaterials have increasingly become a focus of research on neuroprotection and neuroregeneration.Collagen,in terms of brain repair,presents many advantages such as being remarkably biocompatible,biodegradable,versatile and non-toxic.Collagen can be used to form injectable scaffolds and micro/nano spheres in order to:(i) locally release therapeutic factors with the aim of protecting degenerating neurons in neurodegenerative conditions such as Alzheimer's or Parkinson's diseases,(ii) encapsulate stem cells for safe delivery,(iii) encapsulate genetically modified cells to provide a long term source of trophic factors,(iv) fill in the voids from injury to serve as a structural support and provide a permissive microenvironment to promote axonal growth.This mini-review summarizes different applications of collagen biomaterial for central nervous system protection and repair,as well as the future perspectives.Overall,collagen is a promising natural biomaterial with various applications which has the potential to progress the development of therapeutic strategies in central nervous system injuries and degeneration.Buket Ucar Christian Humpel 2018Neural Regeneration Research2018,13,4:3

8Derivation of energy-based base shear force coefficient considering hysteretic behavior and P-delta effects显示文摘A modified energy-balance equation accounting for P-delta effects and hysteretic behavior of reinforced concrete members is derived. Reduced hysteretic properties of structural components due to combined stiffness and strength degradation and pinching effects, and hysteretic damping are taken into account in a simple manner by utilizing plastic energy and seismic input energy modification factors. Having a pre-selected yield mechanism, energy balance of structure in inelastic range is considered. P-delta effects are included in derived equation by adding the external work of gravity loads to the work of equivalent inertia forces and equating the total external work to the modified plastic energy. Earthquake energy input to multi degree of freedom(MDOF) system is approximated by using the modal energy-decomposition. Energybased base shear coefficients are verified by means of both pushover analysis and nonlinear time history(NLTH) analysis of several RC frames having different number of stories. NLTH analyses of frames are performed by using the time histories of ten scaled ground motions compatible with elastic design acceleration spectrum and fulfilling duration/amplitude related requirements of Turkish Seismic Design Code. The observed correlation between energy-based base shear force coefficients and the average base shear force coefficients of NLTH analyses provides a reasonable confidence in estimation of nonlinear base shear force capacity of frames by using the derived equation.Taner Ucar Onur Merter 2018Earthquake Engineering and Engineering Vibration2018,17,1:2
