Clinical correlation of Osseous changes in CT for patients with temporomandibular joint disorders: A Prospective study

BACKGROUND: Temporomandibular joint disorder, as suggested by Bell, which constitutes joint and masticatory system has heterogenous collection of signs and symptoms. Multiple imaging avenues are available to evaluate TMJ disorders. It is extremely useful for revealing the skeletal abnormalities of the TMJ and has excellent predictive value. AIM: The aim of this study is to correlate the clinical characteristics of temporomandibular joint (TMJ) disorder with osseous changes in CT. Methodology: A Prospective analytical study was conducted among 15 patients with symptomatic temporomandibular joint disorders. Patients were clinically examined and parameters were recorded. CT images were taken and interpreted for articular eminence morphology, condylar changes and glenoid thickness. Clinical parameters were then correlated with CT findings. Data was analysed using SPSS software. RESULTS: Sigmoid was the most prevalent articular eminence morphology on both right (80.0%) and left (60.0%) TMJ. Normal condyle was predominantly found in both TMJ (80.0%) followed by flattened condyle (20.0%). The glenoid fossa thickness showed variation of 0.1 and 0.2 mm respectively in the right and left side between normal and flattened condyle. CONCLUSION: Though we have correlated numerous clinical and radiographic features we couldn’t staunchly correlate osseous changes in CT for patients with temporomandibular joint disorders which may be due to smaller sample size

Synthesis of an ordered mesoporous carbon with graphitic characteristics and its application for dye adsorption

An ordered mesoporous carbon (OMC) was prepared by a chemical vapor deposition technique using liquid petroleum gas (LPG) as the carbon source. During synthesis, LPG was effectively adsorbed in the ordered mesopores of SBA-15 silica and converted to a graphitic carbon at 800 °C. X-ray diffraction and nitrogen adsorption/desorption data and high-resolution transmission electron microscopy (HRTEM) of the OMC confirmed its ordered mesoporous structure. The OMC was utilized as an adsorbent in the removal of dyes from aqueous solution. A commercial powder activated carbon (AC) was also investigated to obtain comparative data. The efficiency of the OMC for dye adsorption was tested using acidic dye acid orange 8 (AO8) and basic dyes methylene blue (MB) and rhodamine B (RB). The results show that adsorption was affected by the molecular size of the dye, the textural properties of carbon adsorbent and surface-dye interactions. The adsorption capacities of the OMC for acid orange 8 (AO8), methylene blue (MB) and rhodamine B (RB) were determined to be 222, 833, and 233 mg/g, respectively. The adsorption capacities of the AC for AO8, MB, and RB were determined to be 141, 313, and 185 mg/ g, respectively. The OMC demonstrated to be an excellent adsorbent for the removal of MB from wastewater.Web of Scienc

Characteristics of research in China assessed with Essential Science Indicators

To provide an overview of the characteristics of research in China, a bibliometric evaluation of highly cited papers with high-level representation was conducted during the period from 1999 to 2009 based on the Essential Science Indicators (ESI) database. A comprehensive assessment covered overall performance, journals, subject categories, internationally collaborative countries, national inter-institutionally collaborative institutions, and most-cited papers in 22 scientific fields. China saw a strong growth in scientific publications in the last decade, to some extent due to increasing research and development expenditure. China has been more active in ESI fields of chemistry and physics, but more excellent in materials science, engineering and mathematics. Most publications were concerned with the common Science Citation Index subject categories of multidisciplinary chemistry, multidisciplinary materials and science, and physical chemistry. About one half China's ESC papers were internationally collaborative and the eight major industrialized countries (the USA, Germany, the UK, Japan, France, Canada, Russia, and Italy) played a prominent role in scientific collaboration with China, especially the USA. The Chinese Academy of Sciences took the leading position of institutions with many branches. The "985 Project'' stimulated the most productive institutions for academic research with a huge funding injection and the universities in Hong Kong showed good scientific performance. The citation impact of internationally collaborative papers differed among fields and international collaborations made positive contributions to academic research in China.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000294839700010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Interdisciplinary ApplicationsInformation Science & Library ScienceSCI(E)SSCI20ARTICLE3841-8628
