Wide-area network traffic engineering enables network operators to reduce congestion and improve utilization by balancing load across multiple paths. Current approaches to traffic engineering can be modeled in terms of a routing component that computes forwarding paths, and a load balancing component that maps incoming flows onto those paths dynamically,… (More)
A 32-month-old female child with a history of stage IV favorable biology neuroblastoma with a 123-I MIBG (metaiodobenzylguanidine scan) avid adrenal mass, with retroperitoneal nodal extension and bony metastasis, was in complete remission after intense multimodal therapy. Seventeen months after diagnosis a surveillance 123-I MIBG scan showed abnormal tracer… (More)
The HGF/c-Met pathway is an important regulator of signaling pathways responsible for invasion and metastasis of most human cancers, including prostate cancer. Exposure of DU145 prostate tumor cells to HGF stimulates the PI3-kinase and MAPK pathways, leading to increased scattering, motility, and invasion, which was prevented by the addition of EGCG. EGCG… (More)
Rapid advances in communications and computing technology have opened up new opportunities for clinical teleradiology. The quality of teleradiology reporting, when carried out properly, is on par with onsite reporting, and offers the potential for increased accuracy and improved patient outcomes. Local and international industry organisations and… (More)
OBJECTIVES Statins are a well-known primary and secondary prevention drug for cardiovascular disease and NICE guidelines have been issued to identify key indicators for their use. An audit looking into statin prescribing for medical inpatients was carried out in two geographically distinct London hospitals. DESIGN A prospective inpatient audit of medical… (More)
An isothiocyanate-functionalized tetraphenylethene is synthesized and used as a fluorescent bioprobe for mitochondrion imaging with high specificity and photostability. The covalent conjugation of the bioprobe to mitochondrial proteins endows it with high resistance to microenvironmental changes, enabling it for real-time monitoring of mitophagy.
The first mitochondrion-anchoring photosensitizer that specifically generates singlet oxygen (1 O2 ) in mitochondria under white light irradiation that can serve as a highly effective radiosensitizer is reported here, significantly sensitizing cancer cells to ionizing radiation. An aggregation-induced emission luminogen (AIEgen), namely DPA-SCP, is… (More)
A tetraphenylethene-based caged compound (TPE-C) is designed and synthesized. TPE-C is non-fluorescent either in solution or in aggregated state, but its emission can be induced to emit strong cyan emission in the aggregated state by UV irradiation. This property enables TPE-C to be applied in photo-patterning and anti-counterfeiting related areas.
