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.

Ecological interactions between flowers and pollinators are all about timing. Flower opening/closing and scent emissions are largely synchronized with pollinator activity, and a circadian clock regulates these rhythms. However, whether the circadian clock increases a plant＇s reproductive success by regulating these floral rhythms remains untested. Flowers of Nicotiana attenuata, a wild tobacco, diurnally and rhythmically open, emit scent and move vertically through a 140° arc to interact with nocturnal hawkmoths. We tethered flowers to evaluate the importanceof flower positions for Manduca flower position dramatically sexta-mediated pollinations; nfluenced pollination. We examined the pollination success of phase-shifted flowers, silenced in circadian clock genes, NaZTL, NaLHY, and NaTOCI, by RNAi. Circadian rhythms in N. attenuata flowers are responsible for altered seed set from outcrossed pollen.

Recent literature dealing with nongovemmental organizations （NGOs） claims that NGOs have little incentive to base their decisions and strategies on local needs and instead are governed largely by their current and prospective donors （McGann ＆ j.hnstone, 2006; Prakash ＆ Gugerty, 2010; Bollen et al., 2005）. To test this claim, I have created a quantitative experiment in the US and Uganda in which organizations were randomly assigned to a control group or one of four treatment groups based on the main stakeholders of the NGO market---donors, local government officials, proj.ct beneficiaries, and NGO peers. In each group, organizations were invited to take a survey and were told that the results of their survey would be published to one of these four stakeholder groups. Thus, differences in response rates between groups are attributed to differences in the degree of concern that NGOs felt about the opinions of a given stakeholder. I hypothesized that NGOs care more about the opinions of their donors than other stakeholder groups and found support for this hypothesis among NGOs in the US.
