Ag2S nano dots have already bee n dem onstrated as promisi ng n ear-i nfrared (NIR-II, 1.0-1.45 pm) emitting nan oprobes with low toxicity, high penetration and high resolution for in vivo imaging of, for example, tumors and vasculature. In this work, we have systematically investigated the pote ntial applicati on of function alized Ag2S nano dots for accurate imaging of damaged myocardium tissues after a myocardial in farction in duced by either partial or global ischemia. Ag2S nano dots surface-function alized with the an giote nsin II peptide (ATI I) have show n over 10-fold enhanced binding efficiency to damaged tissues than non-specifically (PEG) functionalized Ag2S nanodots due to their interaction with the upregulated angiotensin II receptor type I (AT1R). It is demonstrated how the NIR-II images generated by ATII-functionalized Ag2S nanodots contain valuable information about the location and extension of damaged tissue in the myocardium allowing for a proper identification of the occluded artery as well as an in direct evaluati on of the damage level. The pote ntial applicati on of Ag2S nano dots in the n ear future for in vivo imaging of myocardial infarction was also corroborated by performing proof of concept whole body imaging experiments.

Excision margins in squamous cell carcinoma of the tongue: A retrospective audit and review of the literature

引用

Open Journal of Stomatology 2013年第1期3卷 70-74页

作者： miriam Thake Athanasis Kalantzis Maxillofacial Surgery Oxford Radcliffe Hospitals Oxford UK Oxford University Medical School Oxford Radcliffe Hospitals Oxford University Oxford UK

The incidence of close and involved tongue resection margins for squamous cell carcinoma (SCC) were reviewed with the aim to identify any possible need for change in the surgical approach to glossectomies. The histopathological reports of 101 partial glossectomies for SCC between 2006 and 2012 were retrospectively reviewed. Results: Overall 52 (51.5%) patients had one or more close or involved margin and 9 (8.9%) had both close and involved margins. 42 (41.5%) patients had close margins and 11 (10.9%) had involved margins. The inferior/lateral muscoal margin was most frequently close/involved (32%) followed by deep margin (27%). The anterior margin was least close/involved (5%). The posterior and superior/medical margins were close/involved in 12% and 11% of cases respectively. Conclusions: 52.5% of patients had close or involved margins following surgery, potentially requiring further treatment to avoid an increased risk of tumour recurrence and the associated increase in morbidity and mortality. The inferior/lateral and deep margins were most frequently involved possible due to the anatomical difficulties visualising and dissecting these margins. The potential explanations for these disparities and possible solutions are discussed.

Medical treatment for gastro-entero-pancreatic neuroendocrine tumours

World Journal of Gastrointestinal Oncology 2016年第4期8卷 389-401页

Gastro-entero-pancreatic neuroendocrine neoplasms(GEPNENs) represents a various family of rare tumours. Surgery is the first choice in GEP-NENs patients with localized disease whilst in the metastatic setting many other treatment options are available. Somatostatin analogues are indicated for symptoms control in functioning tumours. Furthermore they may be effective to inhibit tumour progression. GEP-NENs pathogenesis has been extensively studied in the last years therefore several driver mutations pathway genes have been identified as crucial factors in their tumourigenesis. GEP-NENs can over-express vascular endothelial growth factor(VEGF), basic-fibroblastic growth factor, transforming growth factor(TGF-α and-β), platelet derived growth factor(PDGF), insulin-like growth factor-1(IGF-1) and their receptors PDGF receptor, IGF-1 receptor, epidermal growth factor receptor, VEGF receptor, and c-kit(stem cell factor receptor) that can be considered as potential targets. The availability of new targeted agents, such as everolimus and sunitinib that are effective in advanced and metastatic pancreatic neuroendocrine tumours, has provided new treatment opportunities. Many trials combing new drugs are ongoing.

Retinal and Choroidal Alterations in Migraine Patients Compared to Normal Healthy Controls

引用

Journal of Behavioral and Brain Science 2023年第10期13卷 185-197页

作者： miriam L. Conway Irene Ctori Department of Optometry and Visual Science City University of London London UK

Purpose: Migraine is an incapacitating neurovascular disorder that primarily affects the working-age population. Researchers have postulated that the transient vascular alterations during each migraine attack lead to ischemic damage in the eye which can be measured via optical coherence tomography. Methods: We recruited 29 volunteers: 13 migraineurs (mean age 28 ± 8.8 years;12 female and 1 male) and 16 age-matched controls (mean age 26.6 ± 6.9;9 female and 7 male). All individuals underwent a detailed ophthalmic examination by a qualified optometrist and a Migraine Disability Assessment. The investigators were blind to the migraine diagnosis. Retinal Nerve Fiber Layer (RNFL) thickness, Retinal Thickness (RT), Ganglion Cell Complex (GCL), ranging from the inner-limiting membrane to the inner plexiform layer, and Choroidal Thickness (CT) were measured using the 3D OCT-1Maestro, Topcon, a Spectral Domain OCT (SD-OCT) device. Results: In the migraine population average RNFL was lower for several parameters. However, results did not reach statistical significance. A significant decrease in the right eye inferior parafoveal ganglion cell layer in the migraine group of patients (mean = 25.15, SD = 4.08) compared to normal healthy controls (mean = 28.81, SD = 4.85;t = (27) = 2.17, p = 0.039) was documented. No other ganglion cell layer or choroidal thickness reached significance. No significant relationship between ocular thickness parameters and MIDAS score, parameters and either MIDAS score or frequency of headaches was found. Conclusion: A significant decrease in the right inferior parafoveal ganglion cell layer for migraine patients was reported. All other parameters did not reach significance. .
