Use of bone morphogenetic proteins in mesenchymal stemcell stimulation of cartilage and bone repair

引用

World Journal of Stem Cells 2016年第1期8卷 1-12页

作者： sonia Scarfì Department of Earth Environment and Life SciencesUniversity of Genova16132 GenovaItaly

The extracellular matrix-associated bone morphogenetic proteins(BMPs) govern a plethora of biological processes. The BMPs are members of the transforming growth factor-β protein superfamily, and they actively participate to kidney development, digit and limb formation, angiogenesis, tissue fibrosis and tumor development. Since their discovery, they have attracted attention for their fascinating perspectives in the regenerative medicine and tissue engineering fields. BMPs have been employed in many preclinical and clinical studies exploring their chondrogenic or osteoinductive potential in several animal model defects and in human diseases. During years of research in particular two BMPs, BMP2 and BMP7 have gained the podium for their use in the treatment of various cartilage and bone defects. In particular they have been recently approved for employment in non-union fractures as adjunct therapies. On the other hand, thanks to their potentialities in biomedical applications, there is a growing interest in studying the biology of mesenchymal stem cell(MSC), the rules underneath their differentiation abilities, and to test their true abilities in tissue engineering. In fact, the specific differentiation of MSCs into targeted celltype lineages for transplantation is a primary goal of the regenerative medicine. This review provides an overview on the current knowledge of BMP roles and signaling in MSC biology and differentiation capacities. In particular the article focuses on the potential clinical use of BMPs and MSCs concomitantly, in cartilage and bone tissue repair.

Exploring aramid as emerging contender for CO_2 capture

引用

Chinese Journal of Chemical Engineering 2016年第7期24卷 850-855页

作者： sonia Zulfiqar Muhammad Ilyas Sarwar Department of Chemistry School of Natural Sciences (SNS) National University of Sciences and Technology (NUST) Department of Chemistry Quaid-i-Azam University

To prevent CO_2 accumulation in the atmosphere generated from scorching of fossil fuels, carbon capture and sequestration(CCS) technology is considered as a potential route to mitigate the emissions of CO_2 from reaching the atmosphere. Power generation from sources such as gas, coal and biomass can fulfill the energy demand more readily than many other sources of electricity production. Thus these sources may be retained as important alternative option in the global energy cycle. In order to curtail CO_2, porous aramid network was fabricated by the condensation of 1,3,5-benzenetricarbonyl trichloride and 1,3-phenylenediamine in 1,4-dioxane solvent. Aramid was characterized for various analyses including FTIR, XRD, TGA, BET surface area and pore size analysis, FESEM and CO_2 adsorption measurements. Excellent thermal stability was provided by strong amide linkages in the polymer backbone. Optimum CO_2 uptake of aramid was achieved to be 23.14 mg·g^(-1) at 273 K at 0.1 MPa. The basic amide groups of network structure showed greater affinity for CO_*** thermal stability of aramid makes it a promising sorbent for CO_2 capture in adverse conditions.

Dependence of Upper Atmosphere Photochemistry on the Shape of the Diurnal Cycle of the Photolysis Rates

引用

Advances in Atmospheric Sciences 2006年第2期23卷 207-214页

作者： sonia MONTECINOS Patricia BARRIENTOS Center of Advanced Studies in Arid Zones (CEAZA) University of La Serena La SerenaChile Department of Physics University of La Frontera TemucoChile

A photochemical model of the atmosphere constitutes a non-linear, non-autonomous dynamical system, enforced by the Earth＇s rotation. Some studies have shown that the region of the mesopause tends towards non-linear responses such as period-doubling cascades and chaos. In these studies, simple approximations for the diurnal variations of the photolysis rates are assumed. The goal of this article is to investigate what happens if the more realistic, calculated photolysis rates are introduced. It is found that, if the usual approximations-sinusoidal and step fiunctions—are assumed, the responses of the system axe similar： it converges to a 2-day periodic solution. If the more realistic, calculated diurnal cycle is introduced, a new 4-day subharmonic appear.

Modern planktonic foraminifera from the eastern Indian Ocean

引用

Acta Oceanologica Sinica 2018年第10期37卷 46-63页

作者： MUNIR sonia SUN Jun Tianjin Key Laboratory of Marine Resources and Chemistry Tianjin University of Science and Technology Research Centre for Indian Ocean Ecosystem Tianjin University of Science and Technology

A brief morphometric study of the recent planktonic foraminifera in the eastern Indian Ocean was provided with the taxonomic key to species, synonyms, SEM microphotographs of shells and chamber arrays. By recent classification, currently 20 species representing 13 genera and 6 families （Canderinidae, Heterohelicoidae, Hedbergellidae, Higerigerinoidae, Globigerinoidae, and Globorotaloidae） identified from the planktonic material of the eastern Indian Ocean up to a depth of 200 m. Their distribution in water （0-200 m） also reports on the new range of expansion in the eastern Indian Ocean, with Dentigloborotalia anfracta, Hastigerina pelagica, Streptochilus globigerus, Globigerinella calida, Globigerinella adamsi, Orcadia reidelii, Tenuitella parkerae, Tenuitella compressa, reported for the first time in this study area. In general, only around 50 planktonic species are valid worldwide, more specifically the species, e.g., H. pelagica, G. calida, G. adamsi, S. globigerus, O. riedeli, T. parkerae, T. compressa, which occur in the eastern Indian Ocean to fill the the paucity of the recent regional taxonomic literature and the problematic identification from the eastern Indian Ocean. This work aims to bridge this gap and help scientists, managers, educators and students to identify plankton foraminifers by using species notes and images.

The first snapshot study on horizontal distribution and identification of five peritrich ciliates (Genus Vorticella Linnaeus and Zoothamnium Bory de St. Vincent) from the eastern Indian Ocean

引用

Acta Oceanologica Sinica 2018年第10期37卷 79-85页

Epipont peritrich ciliates are one of the most sessilie protists that attached to the substrate of zooplankton communities especially copepods and crustaceans. Peritrich ciliates can be solitary or colonial form found from the coastal zones and embayment around the world. Present research report is the first snapshot study of the peritrich ciliates and the horizontal distribution in open waters from surface to 200 m depth in the eastern Indian Ocean. Recently, five peritrich ciliates, e.g., Vorticella oceanica, Zootharnnium alternans, Z. alrasheidi, Z. pelagicum, and Z. marinum were collected from plankton net tow samples during the cruise from April 10 to May 13, 2014. The characteristics of the peritrich ciliate were determined according to the shape of the zooids, the ciliary structure and the stalks. The morphometric shape, sizes and characters also explained by examination under light/scanning electron microscopy. Vorticella oceanica and Z. pelagicum showed their association with host such as diatom （i.e, Chaetoceros coarctatus） and copepod （Oithona brevicornis） including some individuals around the dinoflagellate species （Ceraitum tripose）. The distribution of these sessilid ciliates was dominated by the V. oceanica, Z. pelagicum and Z. rnarinurn at the southeast zone while the large colonies of Z. alrasheidi observed at the Bay of Bengal. This distribution can be influenced by substrate availability like diatom （Ch. coarctatus） and copepods （O. brevicornis）.
