MSCs were allowed to differentiate into osteoblasts on all the three substrates with the addition of osteogenic differentiation media, and observations were made at an interval of day 7, day 14, and day 21. Immunofluorescence assays were conducted to observe for expressions of bone proteins such as osteopontin (OP) and osteonectin (ON) that are considered as markers of osteogenic lineage. Cell proliferation was determined using the MTT assay. Calcium mineral deposits of these differentiated MSCs were quantified using the Alizarin Red assay. The differentiated MSCs tend to produce both OP and ON on all the three substrates and the amount of OP and ON expressed increased overtime. A decrease in cell proliferation was observed on day 14 in comparison to day 7. Quantification of calcium mineral deposits show that nanoporous-Si induces the highest level of calcium mineral production in comparison to bare and microporous-Si when cultured for a period of 21 days. The data suggest that nanoporous silicon is a suitable scaffold for the differentiation of MSCs to osteoblasts, and provides future potentials for its use in animal experiments.","PeriodicalId":231556,"journal":{"name":"2016 International Conference on Systems in Medicine and Biology (ICSMB)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121247026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This entire system is made wearable and functional in outside lab environment without requirement of technical expert. We are using cheapest (INR 6,800) available NeuroSky Brainwave Mobile (EEG sensor). Instead of using large number of electrode by applying gel between scalp and electrode as done in traditional EEG this sensor uses single non-invasive dry electrode sensor. So it can directly be placed on head and taken off as a head band without any surgery or using any gel making it functional, wearable and portable in outside lab environment . This makes BCI (Brain Computer Interface) much easy to use and affordable. Taking in account that subject has to alter his mental state to control the chair so response to sudden obstacle and hurdles will be difficult and not simultaneously which can be very dangerous in making assistive machine for locomotion in uneven environments. Hence we have added ultrasonic, infrared, LDR (Light Detecting Resistance), temperature, gas, inertial sensor along with EEG sensor. These sensor will do the trajectory mapping and the subject's mental state will control the driving in this safe trajectory, eye blinks will be used for conscious maneuvering of wheel chair and an instantaneous graph showing the subjects mental state would be displayed for feedback. So during subject's conscious state it will be semi-autonomous and in unconscious or sleepy state fully autonomous.","PeriodicalId":231556,"journal":{"name":"2016 International Conference on Systems in Medicine and Biology (ICSMB)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121784351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work proposes that an automated and computational method, Hierarchical Region Splitting (HRS) of Susceptibility Weighted Images (SWI) can identify iron oxide labeled human neural stem cells (hNSCs) within the hypoxic-ischemic brain. Using a unilateral carotid artery occlusion model in neonatal rat pups, we implanted hNSCs that were labeled with Feridex (iron-oxide agent). The rats were then non-invasively imaged (1–90 days post implantation) using SWI magnetic resonance imaging (MRI), which enhances visualization of hypointensity areas that contain iron-oxide labeled hNSCs. SWI images were further enhanced by creating minimum intensity projections (MIP's) from raw magnitude images that were combined with phase images. SWI, due to its sensitivity to paramagnetic compounds, such as iron oxide, resulted in an 8-fold enhancement of small regions of iron oxide labeled stem cells. HRS analysis allowed for semi-automatic detection of hNSCs from SWI images. We found hNSCs in the striatum and regions adjacent to the lesion that corresponded to histological Prussian blue staining, confirming the presence of hNSCs in the areas identified by HRS. hNSC volumes were increased at 30 days and then plateaued until 90 days post implantation. Phase values (radians) were shown to be increased in MR images containing stem cells at later time points consistent with a reduction in iron oxide as hNSCs replicate and migrate from the implantation site. Quantitative SWI derived hNSC volumes were similar to that previously reported. Our results confirm that HRS in conjunction with the high sensitivity of SWI could be used to monitor iron-labeled hNSCs in a clinically relevant manner.","PeriodicalId":231556,"journal":{"name":"2016 International Conference on Systems in Medicine and Biology (ICSMB)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134286963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
