Small Molecule Organic Nanostructures—Fabrication and Properties

Journal of Materials Science & Technology 2008年第4期24卷 563-568页

Organic materials are of great interest for the development of low cost electronic and optoelectronic devices. Although majority of research on organic materials is concerned with synthesis of novel compounds and organic thin films, organic nanostructures are attracting increasing interest in recent years. We briefly review different growth methods of organic nanostructures, which can be roughly divided into vapor deposition methods and self-assembly techniques in solution. Then we highlight some interesting properties of organic nanostructures, as well as possible applications, includinf field emission, electronic and optoelectronic devices.

Clinicopathological survey of 23 patients with lacrimal fossa lesions in Hong Kong

引用

International Journal of Ophthalmology(English edition) 2011年第3期4卷 311-313页

作者： Danny Siu-Chun Ng Edwin chan kin Yau Clement wai-Nang chan Department of Ophthalmology Tung Wah Eastern Hospital

AIM: To survey the clinicopathological correlations of lacrimal fossa lesions in the Hong Kong population. METHODS: A total of 23 patients with lacrimal fossa lesions were identified radiologically. The mean age at the time of diagnosis was 52 year-old. The medical records of patients diagnosed with lacrimal fossa lesions and subsequently underwent radiological investigations were collected and reviewed retrospectively throughout a six years period from 2000 to 2006 from three regional hospitals (Tung Wah Eastern Hospital, Pamela Youde Nethersole Eastern Hospital and Queen Mary Hospital) belonging to the Hong Kong Mega Cluster. Patient demographics, presenting signs and symptoms, imaging modalities, pathological reports and subsequent management were recorded. RESULTS: The most common initial presenting symptom was upper lid swelling (83%) followed by proptosis (13%). 19 patients (83%) had benign lacrimal fossa lesion and 4 patients (17%) had malignancy. Three of the malignancies were lymphomas and one was adenoid cystic carcinoma. CONCLUSION: Age is an important factor in considering the differential diagnosis of lacrimal fossa lesion. Lymphoproliferative diseases have the highest incidence in patients over 60 years of age while inflammatory lesions are more common in younger patients in Hong Kong.

AIM: To evaluate the outcome after surgery for unilateral superior oblique(SO) palsy in ***: The medical records of 39 patients that underwent surgery for unilateral SO palsy between January 2003 and December 2012 at Caritas Medical Centre, Hong Kong, were retrospectively reviewed. All surgeries were performed by a single surgeon. Pre-operative assessments for vertical deviation, cyclo-deviation, and Knapp’s classification were obtained to determine the nature and degree of surgical *** deviation was measured at 1wk; 1, 6mo and on last follow-up day post-operatively. Cyclo-deviation was measured on last follow-up day ***: During the 10 y period, 39 subjects were recruited. The most common etiology was congenital(94.9%). Knapp’s Type III(66.7%) and Type I(12.8%)classifications were the most common subtypes. To treat SO palsy, the most common surgical procedures were:isolated inferior oblique(IO) anteriorization(41.0%),isolated IO myectomy(10.3%), and isolated IO recession(10.3%). At 3.5 ±2.1y post-operatively, the vertical deviation was significantly reduced(15.1 ±6.2 PD versus0.5±1.4 PD, P <0.0001) without significant improvement in cyclo-deviation(P =0.5). Initial vertical deviation was correlated with cyclo-torsion(r =0.4, P =0.007). Those with over-correction had greater initial vertical deviation(19.4±7.2 PD versus 13.2±4.3 PD, P =0.003). After a single operation, 84.6% of subjects achieved a vertical deviation within ±3 PD.· CONCLUSION: The majority of subjects achieved corrected vertical deviation after a single surgery although there was no improvement in *** with over-correction of primary position deviation had greater preoperative vertical deviation and it may be related to simultaneous multiple muscle surgery.
