cas WebCaster and Hybrid Flash Multicasting By communicationtransformation.blogspot.com Published On :: Tue, 26 Oct 2010 20:17:00 +0000 MediaPlatform WebCaster and Adobe's Flash Media Enterprise Server 4 with Hybrid Flash Multicasting bring a game changing solution to the challenge of delivering video to the enterprise without requiring a seven figure hardware investment for multicasting. Up to now, solutions for managing streaming video bandwidth issues required networks of expensive hardware, ranging from Enterprise Content Delivery Networks to WAN Acceleration devices. And all of these solutions dictated Windows Media as your video format. Hybrid Flash Multicasting offers a better way; it works seamlessly with traditional IP multicast networks AND it also provides a Peer Assist multicast solution for the parts of your network that are not IP multicast enabled. Hybrid Flash Multicasting is an outstanding solution because it: 1) allows corporations to continue leveraging the hardware investments they have made and utilize traditional IP Multicasting with Flash instead of Windows Media. 2) allows corporations to reach bandwidth-challenged locations that are not on the multicast WAN or new locations whose networks are not multicast-enabled with a relatively low cost Peer Assist solution (because it does not require new routers and configuration of switches, etc.). This solution solves the challenge of allowing video to reach 100% of your desktops without requiring a million dollar investment in a new eCDN. And unlike other peering solutions, there is no proprietary agent that has to be propagated to every desktop. All your employees' computers need is the latest Flash player. Here is how MediaPlatform fits into the equation: Our WebCaster software is the only streaming video solution that integrates the multicast-enabled Flash player, as well as leveraging Flash's ability to create a cross platform viewing experience, switch between multiple live and pre-recorded video sources, switch bit rates and codecs on the fly, support mobile devices, support H.264 and VP6 to create higher quality video at lower bandwidths, etc. With our software you can take advantage of Flash to upgrade your streaming communications to a more functional format that will work behind the firewall and to the public internet, will work on any browser and operating system, and can deliver content to mobile devices.

cas Hybrid Flash Multicasting Article in Flex Developers Journal By communicationtransformation.blogspot.com Published On :: Thu, 28 Oct 2010 23:51:00 +0000 An article about Hybrid Flash Multicasting that features MediaPlatform's CTO, Greg Pulier, recently appeared in the Flex Developer's Journal. Click here to link to the article Here is the opening paragraph: Hybrid Flash multicasting is the second and decisive wave of innovation that will enable enterprises to stream video without overtaxing their network infrastructures. It eliminates the usual tradeoffs between video consumption and network investment, regardless of increased video traffic in budget-constrained corporate networks. Hybrid Flash multicasting also solves the cost and complexity challenges of IP multicasting. By combining a new form of multicasting, known as application multicasting, which leverages a peer-assisted model of video sharing with an IP multicast network, a video stream can reach virtually everyone on the network using existing bandwidth and infrastructure. Hybrid multicasting finally unlocks the full potential for video within the enterprise by combining IP and application multicasting to deliver streaming media using the most efficient algorithms within a dynamic self-optimizing topology.

By www.chathamhouse.org Published On :: Mon, 02 Sep 2024 16:12:14 +0000 Member’s question time: Is Russia losing the South Caucasus? 22 October 2024 — 1:00PM TO 1:30PM Anonymous (not verified) 2 September 2024 Online Join us and ask Chatham House Senior Research Fellow, Natalie Sabanadze anything about the situation in the Caucasus. Submit your questions in advance. Whilst Russia focuses on its illegal invasion of Ukraine, the situation at its southern border is evolving. Relations between the three states in the South Caucasus and Moscow have never been easy as Russia tried to maintain its dominance by leveraging vulnerabilities, playing one side against another to keep conflicts simmering and even engaging in open military aggression. Although the violence seen in the 1990s and early 2000s has abated, the war in Ukraine has had an indirect impact on the region, bringing a change to the status quo.Russia abandoned its long-standing support for Armenia, allowing for the collapse of Nagorny-Karabakh and the restoration of the territorial integrity of Azerbaijan with the backing of Turkey. As a result, Azerbaijan has emerged as a dominant regional player with Baku recently declaring its interest to join BRICS. Turkey’s influence has grown, while Armenia frustrated by Russia’s change of heart has been turning cautiously towards the EU and the US.In Georgia, meanwhile, the ruling party has been consolidating its grasp on power, rolling back democratic reforms and pivoting away from the West. Georgia’s long-awaited European integration process has been suspended, following the adoption of the Russian-style foreign agents legislation.Join us as our Senior Research Fellow in the Russia and Eurasia Programme answers your questions in this quick-fire session assessing the extent to which the Russian influence has changed since the start of the invasion of Ukraine and who is there to fill the vacuum; how geopolitical contestation in the region is going to impact aspirations of Armenia, Azerbaijan and Georgia; and much more.Submit your questions to Natalie Sabanadze in advance of the event.

cas The HRDC domain oppositely modulates the unwinding activity of E. coli RecQ helicase on duplex DNA and G-quadruplex [Enzymology] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 RecQ family helicases are highly conserved from bacteria to humans and have essential roles in maintaining genome stability. Mutations in three human RecQ helicases cause severe diseases with the main features of premature aging and cancer predisposition. Most RecQ helicases shared a conserved domain arrangement which comprises a helicase core, an RecQ C-terminal domain, and an auxiliary element helicase and RNaseD C-terminal (HRDC) domain, the functions of which are poorly understood. In this study, we systematically characterized the roles of the HRDC domain in E. coli RecQ in various DNA transactions by single-molecule FRET. We found that RecQ repetitively unwinds the 3'-partial duplex and fork DNA with a moderate processivity and periodically patrols on the ssDNA in the 5'-partial duplex by translocation. The HRDC domain significantly suppresses RecQ activities in the above transactions. In sharp contrast, the HRDC domain is essential for the deep and long-time unfolding of the G4 DNA structure by RecQ. Based on the observations that the HRDC domain dynamically switches between RecA core- and ssDNA-binding modes after RecQ association with DNA, we proposed a model to explain the modulation mechanism of the HRDC domain. Our findings not only provide new insights into the activities of RecQ on different substrates but also highlight the novel functions of the HRDC domain in DNA metabolisms. Full Article

This year, the forum will have three sessions: Session 1 | 14:05 - 15:00 | Climate Trends In December, a ‘playbook’ to implement the 2015 Paris Agreement was agreed by 196 countries at the UN’s COP24 in Poland. Despite this success, challenges surrounding common reporting requirements, degree-pathways to pursue, increasing ambition and the implementation of NDCs still remain. In this session, Pete Betts, former Head of International Climate and Energy at the UK Department for Business, Energy, and Industrial Strategy, will reflect on developments in the climate agenda and what action should be taken both in the UK and internationally against the backdrop of Brexit. Session 2 | 15:15 - 16:15 | An Outlook for Oil in 2019 The future of crude oil prices for 2019 is perhaps more uncertain than it has been for several years. Following a period between 2014-17 when over-supply banished geopolitics from influencing the oil price, the market appears to be struggling to price political risk. Recently the OPEC Plus agreement was renewed in an effort to curtail production and defend prices but its effectiveness is in question as the shale technology revolution in the US continues to add to global supply - but for how long? Meanwhile, US relations with Saudi Arabia remain uncertain in the aftermath of the murder of Jamal Khashoggi: how might Saudi oil policy unfold? Similarly, how might Iran respond to President Trump’s unilateral abrogation of the JCPOA agreement? In this session, Paul Stevens looks at the geopolitical factors that might influence crude oil prices in 2019. Session 3 | 16:30 - 17:30 | An Outlook for Coal The rapid phase-out of coal-fired power stations is crucial to the delivery of the goals of the Paris Agreement and to the safeguarding of clean air and water and public health. Some policy and economic developments show that the coal sector is in structural decline, and there is growing international momentum behind coal phase-out. At the same time, many of the largest coal trading countries and companies continue to argue the short-term profitability of the sector but at what cost? This session will explore the national and international risks that continued investment in coal present and the developments that could change this in the year ahead.

cas Forecasting Forum 2020 By www.chathamhouse.org Published On :: Wed, 15 Jan 2020 15:35:01 +0000 Forecasting Forum 2020 17 February 2020 — 2:00PM TO 5:00PM Anonymous (not verified) 15 January 2020 Chatham House | 10 St James's Square | London | SW1Y 4LE The Forecasting Forum 2020 will present the latest thinking from the Chatham House Energy, Environment and Resources Department’s senior research team on the dynamics that will affect fossil fuel and energy investments and markets in the year ahead. 14:00 - 14:30 | Introduction and Climate Risks Outlook In the last decade, following the financial crisis, the literature on systemic risks has grown. Systemic risks occur when complex, non-linear, interconnected systems fail, often through relatively small perturbations, as their impacts cascade and amplify across the system. Within this context, climate change is a ‘threat multiplier’ with the risks increasing in scale, frequency and magnitude. Just as complex systems can pass thresholds and tip from a functional state to a non-functional state, so can societies and people’s attitudes. Together risk cascades or systemic risks and attitudinal tipping points have the potential to rapidly change the way the world works. Professor Tim Benton will open the Forecasting Forum 2020 with reflections on what this might mean for the pace and linearity of the fossil fuel transition. 14:30 - 15:30 | Session 1: An Outlook on Oil Prices in 2020 In this session, Professor Paul Stevens will argue that the recent events associated with the assassination of Iranian General Qasem Soleimani have exacerbated the sensitivity of oil markets to political events and brought ‘geopolitics’ back into global oil prices. Up to 2014, geopolitics played a key role in determining oil prices in the paper markets where perceptions and expectations ruled. By 2014, the world was so oversupplied with real oil barrels that the oil price collapsed and little attention was given to geopolitical events as geopolitics became marginalized in the determination of crude oil prices. However, recent events in the Middle East suggest that prices will become increasingly volatile but, at the same time, benefit from a rising geopolitical premium. 15:45 - 16:45 | Session 2: An Outlook for Energy in 2020 Recent years have brought significant disruption to the European power sector. Not only are many of Europe’s major utilities restructuring their businesses in light of decarbonization and technological developments but Brexit has distracted - and detracted from - efforts to create more systemic energy linkages between the UK and the rest of Europe. During his presentation, Antony Froggatt will draw on his ongoing research to outline what he believes are the prevailing challenges and opportunities for the European power sector over the coming year while highlighting some of the most significant global trends.

cas Molecular characterization of the RNA-protein complex directing -2/-1 programmed ribosomal frameshifting during arterivirus replicase expression [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 Programmed ribosomal frameshifting (PRF) is a mechanism used by arteriviruses like porcine reproductive and respiratory syndrome virus (PRRSV) to generate multiple proteins from overlapping reading frames within its RNA genome. PRRSV employs −1 PRF directed by RNA secondary and tertiary structures within its viral genome (canonical PRF), as well as a noncanonical −1 and −2 PRF that are stimulated by the interactions of PRRSV nonstructural protein 1β (nsp1β) and host protein poly(C)-binding protein (PCBP) 1 or 2 with the viral genome. Together, nsp1β and one of the PCBPs act as transactivators that bind a C-rich motif near the shift site to stimulate −1 and −2 PRF, thereby enabling the ribosome to generate two frameshift products that are implicated in viral immune evasion. How nsp1β and PCBP associate with the viral RNA genome remains unclear. Here, we describe the purification of the nsp1β:PCBP2:viral RNA complex on a scale sufficient for structural analysis using small-angle X-ray scattering and stochiometric analysis by analytical ultracentrifugation. The proteins associate with the RNA C-rich motif as a 1:1:1 complex. The monomeric form of nsp1β within the complex differs from previously reported homodimer identified by X-ray crystallography. Functional analysis of the complex via mutational analysis combined with RNA-binding assays and cell-based frameshifting reporter assays reveal a number of key residues within nsp1β and PCBP2 that are involved in complex formation and function. Our results suggest that nsp1β and PCBP2 both interact directly with viral RNA during formation of the complex to coordinate this unusual PRF mechanism. Full Article
cas The added value of 18F-FDG PET/CT compared to 68Ga-PSMA PET/CT in patients with castration-resistant prostate cancer By jnm.snmjournals.org Published On :: 2021-04-23T13:46:28-07:00 Purpose: The 68Ga-PSMA PET/CT is a commonly used imaging modality in prostate cancers. However, few studies have compared the diagnostic efficiency between 68Ga-PSMA and 18F-FDG PET/CT and evaluated whether a heterogeneous metabolic phenotype (especially PSMA-FDG+ lesions) exists in patients with castration-resistant prostate cancer (CRPC). We determined the added value of 18F-FDG PET/CT compared to 68Ga-PSMA PET/CT in CRPC patients and identified CRPC patients who may benefit from additional 18F-FDG PET/CT. Methods: Data of 56 patients with CRPC who underwent both 68Ga-PSMA and 18F-FDG PET/CT from May 2018 to February 2021 were retrospectively analysed. Patients were classified into two groups with or without PSMA-FDG+ lesions. The differences in patient characteristics between the two groups and predictors of patients who having at least one PSMA-FDG+ lesion were analysed. Results: Although both the detection rate (75.0% vs. 51.8%, P = 0.004) and positive lesion number (135 vs. 95) of 68Ga-PSMA PET/CT were higher than 18F-FDG PET/CT, there were still 13/56 (23.2%) patients with at least one PSMA-FDG+ lesion. The prostate-specific antigen (PSA) and Gleason score were both higher in the patients with PSMA-FDG+ lesions than in those without PSMA-FDG+ lesions (P = 0.04 and P<0.001, respectively). Multivariate regression analysis showed that the Gleason score (≥8) and PSA (≥7.9 ng/mL) were associated with the detection rate of patients who had PSMA-FDG+ lesions (P = 0.01 and P = 0.04, respectively). The incidences of having PSMA-FDG+ lesions in low-probability (Gleason score<8 and PSA<7.9 ng/mL), medium-probability (Gleason score≥8 and PSA<7.9 ng/mL or Gleason score<8 and PSA≥7.9 ng/mL), and high-probability (Gleason score≥8 and PSA≥7.9 ng/mL) groups were 0%, 21.7%, and 61.5%, respectively (P<0.001). Conclusion: Gleason score and PSA are significant predictors for PSMA-FDG+ lesions, and CRPC patients with high Gleason score and PSA may benefit from additional 18F-FDG PET/CT. Full Article

cas Exploitation of dihydroorotate dehydrogenase (DHODH) and p53 activation as therapeutic targets: A case study in polypharmacology [Computational Biology] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 The tenovins are a frequently studied class of compounds capable of inhibiting sirtuin activity, which is thought to result in increased acetylation and protection of the tumor suppressor p53 from degradation. However, as we and other laboratories have shown previously, certain tenovins are also capable of inhibiting autophagic flux, demonstrating the ability of these compounds to engage with more than one target. In this study, we present two additional mechanisms by which tenovins are able to activate p53 and kill tumor cells in culture. These mechanisms are the inhibition of a key enzyme of the de novo pyrimidine synthesis pathway, dihydroorotate dehydrogenase (DHODH), and the blockage of uridine transport into cells. These findings hold a 3-fold significance: first, we demonstrate that tenovins, and perhaps other compounds that activate p53, may activate p53 by more than one mechanism; second, that work previously conducted with certain tenovins as SirT1 inhibitors should additionally be viewed through the lens of DHODH inhibition as this is a major contributor to the mechanism of action of the most widely used tenovins; and finally, that small changes in the structure of a small molecule can lead to a dramatic change in the target profile of the molecule even when the phenotypic readout remains static.

cas Thermal proteome profiling in zebrafish reveals effects of napabucasin on retinoic acid metabolism [Research] By www.mcponline.org Published On :: 2020-10-28T08:35:46-07:00 Thermal proteome profiling (TPP) allows for the unbiased detection of drug – target protein engagements in vivo. Traditionally, one cell type is used for TPP studies, with the risk of missing important differentially expressed target proteins. The use of whole organisms would circumvent this problem. Zebrafish embryos are amenable to such an approach. Here, we used TPP on whole zebrafish embryo lysate to identify protein targets of napabucasin, a compound that may affect Signal transducer and activator of transcription 3 (Stat3) signaling through an ill-understood mechanism. In zebrafish embryos, napabucasin induced developmental defects consistent with inhibition of Stat3 signaling. TPP profiling showed no distinct shift in Stat3 upon napabucasin treatment, but effects were detected on the oxidoreductase, Pora, which might explain effects on Stat3 signaling. Interestingly, thermal stability of several aldehyde dehydrogenases (Aldhs) was affected. Moreover, napabucasin activated ALDH enzymatic activity in vitro. Aldhs have crucial roles in retinoic acid metabolism and functionally we validated napabucasin-mediated activation of the retinoic acid pathway in zebrafish in vivo. We conclude that TPP profiling in whole zebrafish embryo lysate is feasible and facilitates direct correlation of in vivo effects of small molecule drugs with their protein targets. Full Article

cas Memory politics: the challenge of commemoration in post-Soviet Eastern Europe and the Caucasus By www.chathamhouse.org Published On :: Tue, 21 Sep 2021 15:39:42 +0000 Memory politics: the challenge of commemoration in post-Soviet Eastern Europe and the Caucasus 5 October 2021 — 1:00PM TO 2:30PM Anonymous (not verified) 21 September 2021 Online This event explores how to address memory and commemoration in the former Soviet states, considering their role in political processes and violent conflict. How the past is remembered and commemorated plays a large role – perhaps too large – in contemporary political debates and in how conflicts are negotiated. Perceptions of history influence people’s actions and are used to judge or dismiss the actions of others. Nowhere is this more so than in the political, territorial and social debates and disputes across the former Soviet Union. This event examines how to address the problems caused by entrenched memory debates – and proposes a framework for ‘ethical political commemoration’ for use across historical enquiry, political processes, and conflict transformation initiatives. The speakers explore the topic through the context of Turkey and the Armenian genocide, as well as more broadly through their own experiences in conflict transformation and peace processes.

cas Ukraine crisis could trigger cascading risks globally By www.chathamhouse.org Published On :: Wed, 16 Mar 2022 13:14:07 +0000 Ukraine crisis could trigger cascading risks globally Expert comment NCapeling 16 March 2022 The effects on the wider world from the Ukraine invasion go far beyond the waves of shock and horror being felt from this escalating conflict. Russia and Ukraine rank 11th and 55th respectively in terms of their national economies but, for the global supply of critical resources such as energy, food, and minerals, these two countries together are far bigger hitters – and both the threat and reality of resource flows from them being reduced have already driven up global prices. The world is already facing a cost-of-living squeeze coming out of the COVID-19 pandemic, so further price spikes or supply constraints have the potential to seriously undermine food and energy security, equitable access to basic goods and services, and social stability around the world – which can then potentially create systemic risks for economies and societies. The global implications of the Ukraine conflict are only just beginning to be explored fully but the immediate impacts of the crisis on global markets are already well-documented. In the first few days after Russia’s invasion, energy prices spiked, triggering further fertilizer price rises – as fertilizer production is highly energy intensive – which in turn is contributing to food price rises because fertilizer costs are an important factor in food production. Further price spikes or supply constraints have the potential to seriously undermine food and energy security, equitable access to basic goods and services, and social stability around the world Interruptions to shipping in the region around Ukraine – as well as globally – have impeded the flow of goods which pushed prices up even further, while economic sanctions on cross-border flows of goods and finance are further adding to market pressures. But this is just the start – these impacts will bring ripple effects which propagate far beyond their point of origin, known as ‘cascading risks’. Risk is a combination of hazard, exposure, and vulnerability – in terms of the Ukraine invasion, the hazard is the conflict and its immediate impacts on the societies and economies of Ukraine and Russia, while exposure relates to the degree to which other countries are likely to be affected depending on how much they are integrated into the global economy or the ‘just in time’ nature of their supply chains. Vulnerability relates to a society’s capacity to mitigate the harmful impacts of the conflict, such as controlling borders, sourcing alternative goods from suppliers, or protecting against price or supply shocks. Risk cascades – the second- and third-order impacts of the original hazard and of responses to that hazard – can interact across sectoral boundaries – as with energy and food, for example – and their compound effect can lead to overall systemic risks for society. Anticipating this potential is essential to understanding the nature and scale of the global ramifications being felt from the Ukraine conflict. Recent work in the UK to assess levels of cascading risks resulting from a changing climate – the UK Climate Change Risk Assessment – provides a valuable framework for thinking about this area. It examines key pathways for risk to cascade through global systems – when applied to the situation in Ukraine, these pathways and their interactions offer an indication of the scale of crisis that citizens face far beyond Ukraine’s and Russia’s borders. Interruptions to the flows of goods and energy In globalized trade networks, localized disruption to supply chains rapidly yields widespread international impacts – of particular concern is the immediate supply of food because most countries rely on lean supply chains and some may only have a few days food within their own borders. Experience from previous food price crises indicate even small interruptions to trade can result in runs on the market and rapid price inflation. In the case of this conflict, the trade interruption will be far from small because, between them, Russia and Ukraine export around one-quarter of all traded wheat, more than three-quarters of traded sunflower oil, and one-sixth of traded maize. Given many people are understandably fleeing this conflict, other countries may struggle to cope as the cost-of-living crisis and urgent efforts to bolster national security infrastructure may squeeze available public funds Energy markets are also a concern because many countries use more energy than they produce and therefore rely on imports of energy or fuel for domestic use. Russia produces around ten per cent of the world’s commercial energy with a concentration of sales in major regions such as the European Union (EU) and China. As with food, a shortfall in energy provision leads to market runs and rapid inflation as actors compete in a tightening space, while poorly designed policy interventions by nations trying to ensure their own security add further pressure to global supply and worsen price rises. In addition, the closely interconnected nature of energy markets means disruption to one fuel – such as gas in this case – affects global prices for other forms of energy. The impact of moving people and money As the last decade richly illustrates, the cross-border flows of people impact those societies absorbing them – for example, contributing to a rise in nationalism – as well as increase the costs of supplying essential resources. Given many people are understandably fleeing this conflict, other countries may struggle to cope as the cost-of-living crisis and urgent efforts to bolster national security infrastructure may squeeze available public funds. Financial flows are crucial to the functioning of global economies, whether for inward investment or insurance and – as Russian citizens may be about to discover – restricting the global flow of money has a serious impact on households. Beyond Russia, the outflow of money from major financial centres such as London to meet insurance claims or to enable infrastructure reinvestment post-conflict may also have severe knock-on economic impacts. The impact on governance and health The global spikes in energy and food prices resulting from these supply chain disruptions will see many countries struggle with rising food and energy insecurity as well as increased inequality. Taken together these conditions create many issues beyond immigration pressures and the associated politics, including increased inequality and civil unrest. This potentially destabilizes governments which has consequences for the stability of an entire region such as interrupted supply chains, the need to deploy peacekeeping forces, or significant flows of aid – all with global consequences far beyond the countries in question. Populations may suffer mental health impacts arising from the Ukraine invasion, whether from the trauma of being forced to leave home to escape conflict, anxiety for the wellbeing and safety of families and friends caught up in it, or a more general anxiety arising from the perception of living in an unstable world.

cas [68Ga]Ga-RAYZ-8009: A Glypican-3-Targeted Diagnostic Radiopharmaceutical for Hepatocellular Carcinoma Molecular Imaging--A First-in-Human Case Series By jnm.snmjournals.org Published On :: 2024-10-01T04:08:08-07:00 To date, the imaging and diagnosis of hepatocellular carcinoma (HCC) rely on CT/MRI, which have well-known limitations. Glypican-3 (GPC3) is a cell surface receptor highly expressed by HCC but not by normal or cirrhotic liver tissue. Here we report initial clinical results of GPC3-targeted PET imaging with [68Ga]Ga-DOTA-RYZ-GPC3 (RAYZ-8009), a peptide-based GPC3 ligand in patients with known or suspected HCC. Methods: [68Ga]Ga-RAYZ-8009 was obtained after labeling the peptide precursor with 68Ga from a 68Ge/68Ga generator and heating at 90°C for 10 min followed by sterile filtration. After administration of [68Ga]Ga-RAYZ-8009, a dynamic or static PET/CT scan was acquired between 45 min and 4 h after administration. Radiotracer uptake was measured by SUVs for the following tissues: suspected or actual HCC or hepatoblastoma lesions, non–tumor-bearing liver, renal cortex, blood pool in the left ventricle, and gastric fundus. Additionally, tumor–to–healthy-liver ratios (TLRs) were calculated. Results: Twenty-four patients (5 patients in the dynamic protocol; 19 patients in the static protocol) were scanned. No adverse events occurred. Two patients had no lesion detected and did not have HCC during follow-up. In total, 50 lesions were detected and analyzed. The mean SUVmax of these lesions was 19.6 (range, 2.7–95.3), and the mean SUVmean was 10.1 (range, 1.0–49.2) at approximately 60 min after administration. Uptake in non–tumor-bearing liver and blood pool rapidly decreased over time and became negligible 45 min after administration (mean SUVmean, <1.6), with a continuous decline to 4 h after administration (mean SUVmean, 1.0). The opposite was observed for HCC lesions, for which SUVs and TLRs continuously increased for up to 4 h after administration. In individual lesion analysis, TLR was the highest between 60 and 120 min after administration. Uptake in the gastric fundus gradually increased for up to 45 min (to an SUVmax of 31.3) and decreased gradually afterward. Conclusion: [68Ga]Ga-RAYZ-8009 is safe and allows for high-contrast imaging of GPC3-positive HCC, with rapid clearance from most normal organs. Thereby, [68Ga]Ga-RAYZ-8009 is promising for HCC diagnosis and staging. Further research is warranted. Full Article
