lab K2 will not be made available for Joomla 4/5 - change of course By www.joomlaworks.net Published On :: Thu, 30 May 2024 20:56:11 +0300 The writing's on the wall. Joomla 4 and 5 are failed CMS releases. They account for around 0.3% of ALL Joomla sites according to W3Techs (https://w3techs.com/technologies/details/cm-joomla). Joomla's official stats (which were introduced near the end of life of Joomla 3 - https://developer.joomla.org/about/stats.html) are far less accurate obviously (e.g. they don't account for Joomla 1.5 > 2.5 sites or older Joomla 3 releases) but still show around 10% of sites use Joomla 4/5, after 3 years of their release. And these stats can be disabled by users of Joomla sites (most do). This means adoption for these versions is close to non-existent. A sad reality, but an understandable one (read my posts on May 30th at https://x.com/joomlaworks for additional context). There is literally nothing to say about how things have evolved for Joomla. At this rate, it will probably be a dead software project within the next couple of years. It's not just the users that are de-motivated, it's the developers too (the Joomla core developers). Few people will enjoy working on Joomla if no one uses it. It just makes sense. As such, and given that we're strongly invested in Joomla 3 (in some of the largest news/media site implementations worldwide with Joomla), we don't plan on giving up on K2 (or Joomla 3). In fact, our goal is to pivot and work on a possible fork, unless a miracle happens and the Joomla core team gets their shit together and works on a true/seamless Joomla 3 to Joomla 5 (or 6?) upgrade. The fork is a reasonable path for us for many reasons but I'd list the following ones here (for now): It'll be exciting to go from K2 (a "half" CMS so to speak) to a full CMS. Any crap that didn't work or half-worked on J3 will be fixed. Sky's the limit. Really. No stupid politics, irrelevant conventions, idiotic patterns to follow. We have a clear goal for K2 (and Joomla) and that's what we're gonna work on. That goal is a fast, reliable. modern CMS that leaves people asking "why WordPress?" Some will nag Joomla 3 uses old code. No it doesn't. It uses a certain design that was popular at the time it was introduced. The only change that is required is for it to be updated so it catches up with PHP's latest versions (for the record, we actively run sites with Joomla 3 / K2 on PHP 8.2). It's a mature code base that can be gradually improved. The fork could be introduced in 2 phases. Phase 1: A re-branding for existing sites to move over their content from com_content to K2 (far less work than switching to Joomla 4/5) and existing Joomla/K2 sites to freshen up their backend. Phase 2: This would be the part we lighten up the core. This means com_content & components like banners, newsfeeds, messages etc., their respective modules and plugins and generally other accumulated crap (like User Notes) that literally noone ever used will be stripped off Joomla. Either way K2 can reproduce most of these stuff far better. Any design changes will be subtle and NOT affect existing Joomla extensions that respected the Joomla UI design. It will also certainly NOT affect extensions that brought in their own design/MVC and so on (think AcyMailing, page builders etc. etc.). If our friend Ryan provides his blessing, we would also love to swap the current Joomla WYSIWYG editor with JCE Core. If not, it's always available either way. We will just upgrade TinyMCE and still install our beloved JCE. This would also be a good time to standardize things like "editor xtd" buttons in a way that they better integrate with the WYSIWYG editor... Features and custom extensions we've used for large scale projects could be integrated in the new CMS, if it makes sense for most users to have. E.g. fast search powered by Elasticsearch is a no-brainer (and we can throw that Smart Search crap out for good). The point is to do something that's fun, while professional at the same time. Backward compatibility will be our holy grail. Anyone that tells it can't are either lazy or just plain bad programmers (hell, we've maintained K2 for Joomla 1.5 to 3 for 15 damn years). We're already in touch with partners to finance this move. On the long term, all we need is a couple of devs, working full time. The next big phase will be infrastructure as required for any modern CMS. That means rebuilding something like the JED, working on documenting use and code etc. At the same time, it's practical to keep everything to a minimum. E.g. there is no reason to use our own forum, but probably go for something like GitHub so we can have everything in a single place: code and discussion, coupled with solid anti-spam (cause let's face it, that's what forums suffer from these days). By keeping things lean and simple, we will work less on infrastructure and more on the CMS's code and features. If you ask "why now", I can respond with 2 things: 1) There's been plenty of time for people to switch to Joomla 4/5. Very few did. 2) It's MUCH worse waiting things out to chart their predefined course than actually fucking doing something about it, even if it fails or doesn't work out. Follow up blog posts will provide more insight into how things will play out in the coming months and how others can join this effort. P.S.

lab Water, Ecosystems and Energy in South Asia: Making Cross-Border Collaboration Work By www.chathamhouse.org Published On :: Wed, 29 Jun 2016 13:19:15 +0000 Water, Ecosystems and Energy in South Asia: Making Cross-Border Collaboration Work Research paper sysadmin 29 June 2016 A new paper sets out the factors that have made previous cross-border projects in South Asia successful, arguing that cooperation around water is feasible despite the region’s political differences and economic assymetries. — Indian people walk in the Ganga riverbed in Allahabad on 1 September 2015. Photo: Getty images. The countries of South Asia share some of the world’s major river basins – the Ganga (or Ganges), the Brahmaputra and the Indus. These rivers and their tributaries flow through seven countries, support more than 1 billion people, irrigate millions of hectares of land and are of cultural importance to many of those who rely on them. River management presents common challenges across the region. These include physical factors such as droughts, flooding, cyclones and climate change, as well political and institutional factors impeding the development of solutions and policies to improve resource management and reduce vulnerability. Water is increasingly seen as a source of competition, with population growth, industrialization and urbanization exacerbating the pressures on supply. Although South Asian examples of regional cooperation in general are limited, there is a clear positive trend. In areas such as disaster response and cross-border power trading, regional and bilateral engagement is beginning to take place. Multilateral official arrangements exist for trade and other economic issues, but there is none on water or ecosystems. However, as the benefits from cooperation become proven, its desirability is likely to gradually enter mainstream policy thinking on water issues. This research paper sets out the factors that have enabled cooperation, and the processes adopted, in previous successful cross-border projects. It focuses on four categories of cooperation: development of early-warning systems for natural disasters, in particular floods; protection of cross-border ecosystems; sharing of learning, through the showcasing of innovative approaches in one country that can be adopted by others; and power trading, in particular the development of hydropower in Bhutan and its export to India. The paper argues that cooperation around water in South Asia is feasible despite political differences and economic asymmetries. Different forms of collective action, and common understanding of both the threats and the shared benefits from cooperation, are required to foster more partnerships within the river basin states. 2016-06-30-water-south-asia-price-mittra (PDF) Full Article

lab Co-crystal structures of HIV TAR RNA bound to lab-evolved proteins show key roles for arginine relevant to the design of cyclic peptide TAR inhibitors [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 RNA-protein interfaces control key replication events during the HIV-1 life cycle. The viral trans-activator of transcription (Tat) protein uses an archetypal arginine-rich motif (ARM) to recruit the host positive transcription elongation factor b (pTEFb) complex onto the viral trans-activation response (TAR) RNA, leading to activation of HIV transcription. Efforts to block this interaction have stimulated production of biologics designed to disrupt this essential RNA-protein interface. Here, we present four co-crystal structures of lab-evolved TAR-binding proteins (TBPs) in complex with HIV-1 TAR. Our results reveal that high-affinity binding requires a distinct sequence and spacing of arginines within a specific β2-β3 hairpin loop that arose during selection. Although loops with as many as five arginines were analyzed, only three arginines could bind simultaneously with major-groove guanines. Amino acids that promote backbone interactions within the β2-β3 loop were also observed to be important for high-affinity interactions. Based on structural and affinity analyses, we designed two cyclic peptide mimics of the TAR-binding β2-β3 loop sequences present in two high-affinity TBPs (KD values of 4.2 ± 0.3 and 3.0 ± 0.3 nm). Our efforts yielded low-molecular weight compounds that bind TAR with low micromolar affinity (KD values ranging from 3.6 to 22 μm). Significantly, one cyclic compound within this series blocked binding of the Tat-ARM peptide to TAR in solution assays, whereas its linear counterpart did not. Overall, this work provides insight into protein-mediated TAR recognition and lays the ground for the development of cyclic peptide inhibitors of a vital HIV-1 RNA-protein interaction. Full Article

lab Harmonized procedures lead to comparable quantification of total oxylipins across laboratories [Research Articles] By www.jlr.org Published On :: 2020-11-01T00:05:43-07:00 Oxylipins are potent lipid mediators involved in a variety of physiological processes. Their profiling has the potential to provide a wealth of information regarding human health and disease and is a promising technology for translation into clinical applications. However, results generated by independent groups are rarely comparable, which increases the need for the implementation of internationally agreed upon protocols. We performed an interlaboratory comparison for the MS-based quantitative analysis of total oxylipins. Five independent laboratories assessed the technical variability and comparability of 133 oxylipins using a harmonized and standardized protocol, common biological materials (i.e., seven quality control plasmas), standard calibration series, and analytical methods. The quantitative analysis was based on a standard calibration series with isotopically labeled internal standards. Using the standardized protocol, the technical variance was within ±15% for 73% of oxylipins; however, most epoxy fatty acids were identified as critical analytes due to high variabilities in concentrations. The comparability of concentrations determined by the laboratories was examined using consensus value estimates and unsupervised/supervised multivariate analysis (i.e., principal component analysis and partial least squares discriminant analysis). Interlaboratory variability was limited and did not interfere with our ability to distinguish the different plasmas. Moreover, all laboratories were able to identify similar differences between plasmas. In summary, we show that by using a standardized protocol for sample preparation, low technical variability can be achieved. Harmonization of all oxylipin extraction and analysis steps led to reliable, reproducible, and comparable oxylipin concentrations in independent laboratories, allowing the generation of biologically meaningful oxylipin patterns.

lab Bioavailability and spatial distribution of fatty acids in the rat retina after dietary omega-3 supplementation [Research Articles] By www.jlr.org Published On :: 2020-12-01T00:05:39-08:00 Spatial changes of FAs in the retina in response to different dietary n-3 formulations have never been explored, although a diet rich in EPA and DHA is recommended to protect the retina against the effects of aging. In this study, Wistar rats were fed for 8 weeks with balanced diet including either EPA-containing phospholipids (PLs), EPA-containing TGs, DHA-containing PLs, or DHA-containing TGs. Qualitative changes in FA composition of plasma, erythrocytes, and retina were evaluated by gas chromatography-flame ionization detector. Following the different dietary intakes, changes to the quantity and spatial organization of PC and PE species in retina were determined by LC coupled to MS/MS and MALDI coupled to MS imaging. The omega-3 content in the lipids of plasma and erythrocytes suggests that PLs as well as TGs are good omega-3 carriers for retina. However, a significant increase in DHA content in retina was observed, especially molecular species as di-DHA-containing PC and PE, as well as an increase in very long chain PUFAs (more than 28 carbons) following PL-EPA and TG-DHA diets only. All supplemented diets triggered spatial organization changes of DHA in the photoreceptor layer around the optic nerve. Taken together, these findings suggest that dietary omega-3 supplementation can modify the content of FAs in the rat retina. Full Article
lab MSstatsTMT: Statistical Detection of Differentially Abundant Proteins in Experiments with Isobaric Labeling and Multiple Mixtures [Technological Innovation and Resources] By www.mcponline.org Published On :: 2020-10-01T00:05:25-07:00 Tandem mass tag (TMT) is a multiplexing technology widely-used in proteomic research. It enables relative quantification of proteins from multiple biological samples in a single MS run with high efficiency and high throughput. However, experiments often require more biological replicates or conditions than can be accommodated by a single run, and involve multiple TMT mixtures and multiple runs. Such larger-scale experiments combine sources of biological and technical variation in patterns that are complex, unique to TMT-based workflows, and challenging for the downstream statistical analysis. These patterns cannot be adequately characterized by statistical methods designed for other technologies, such as label-free proteomics or transcriptomics. This manuscript proposes a general statistical approach for relative protein quantification in MS- based experiments with TMT labeling. It is applicable to experiments with multiple conditions, multiple biological replicate runs and multiple technical replicate runs, and unbalanced designs. It is based on a flexible family of linear mixed-effects models that handle complex patterns of technical artifacts and missing values. The approach is implemented in MSstatsTMT, a freely available open-source R/Bioconductor package compatible with data processing tools such as Proteome Discoverer, MaxQuant, OpenMS, and SpectroMine. Evaluation on a controlled mixture, simulated datasets, and three biological investigations with diverse designs demonstrated that MSstatsTMT balanced the sensitivity and the specificity of detecting differentially abundant proteins, in large-scale experiments with multiple biological mixtures.

lab The Chatham House Sustainable Laboratories Initiative: Prior Assessment Tool By www.chathamhouse.org Published On :: Fri, 14 Jun 2019 14:02:35 +0000 The Chatham House Sustainable Laboratories Initiative: Prior Assessment Tool Other resource sysadmin 14 June 2019 Laboratories are critical for supporting effective infectious disease surveillance and outbreak response. This tool is meant to help structure a conversation between funding partners and recipient countries on how to most effectively establish or repurpose laboratories in low-resource environments. — Copyright: Getty Images/ER Productions Limited Introduction Laboratories are critical for supporting effective infectious disease surveillance and outbreak response, and lack of adequate laboratory capacity is a global challenge. As part of global health security initiatives, cooperative threat reduction efforts and international development programmes, sophisticated laboratories have been provided to mitigate biological threats and bolster a country’s capacity for detection, diagnosis and storage of high-consequence pathogens. Very often, these use the assumptions, standards and templates applied in high-income countries. However, it can be difficult or even impossible to sustain these facilities in low-resource environments. There can sometimes be limited local technical capacity and capability, which can result in a high reliance on imported expertise, skills, equipment and other resources. Sustainability can therefore be hard to achieve. In addition, when a funding partner withdraws, the laboratories can become disused, foundering without the trained personnel and financial resources to sustain them. To help address this situation, a proposal gaining increasing support internationally is to adopt an approach based on a local risk assessment, whereby laboratories are appropriately and optimally tailored to the local risks and to the resources available, both in the short and longer term, without compromising biosafety and biosecurity. A Chatham House workshop was convened in Abuja, Nigeria, in 2018 to explore what West African countries would find most appropriate in terms of building laboratory capacity, what the main challenges have been so far, and what needs to be done to improve the sustainability of laboratories in the region. It emerged that there was a need for a more structured conversation between the funding partner and recipient country early in the process – prior to embarking on the detailed planning phase for the establishment or repurposing of a laboratory. This should involve careful consideration and an assessment of existing and planned capacity, needs and contextual issues, together with proposals for how to address the issues revealed, so that any ensuing laboratory demonstrably supports the national strategy and therefore flourishes. The purpose of this tool This tool aims to provide a structure for such a conversation. Developed in close collaboration with international experts and West African stakeholders, it seeks to increase local ownership and help partners ensure they have given due attention to all the relevant aspects, including risks and benefits, that need to be considered at an early stage. It should provide clarity on what is needed and improve the sustainability of any laboratory project that might result from the discussions. The tool can be applied when a new laboratory is being considered, or when an existing laboratory is to be repurposed or strengthened. It is also appropriate for use with public health, veterinary and environmental laboratories. Although the tool was developed in the context of high-consequence pathogens in Africa, it is anticipated that it will find global application. It should support recipient countries to take stock of their capacities and capabilities, identify gaps, conduct an analysis of their needs and to develop the business case that can assist in seeking the necessary political and financial support for the laboratory. Meanwhile, it should facilitate the process of due diligence for the funding partner and provide a better understanding of what the recipient country perspective and realities are, and what the scale and nature of any investment might be. 2019-06-18-Sustainable-Laboratories-Initiative (PDF) Full Article
lab The Justice Laboratory: International Law in Africa By www.chathamhouse.org Published On :: Wed, 30 Mar 2022 13:44:10 +0000 The Justice Laboratory: International Law in Africa Book dora.popova 30 March 2022 The Justice Laboratory is the first major study of the institutions created to enforce international criminal justice standards in Sub-Saharan Africa, including the UN tribunal for the Rwandan genocide. Since the Second World War, the United Nations and other international actors have created laws, treaties, and institutions to punish perpetrators of genocide, war crimes, and crimes against humanity. But international criminal justice now seems to be a declining force — its energy sapped by long delays in prosecutions, lagging public attention, and a globally rising authoritarianism that disregards legal niceties. The Justice Laboratory reviews five examples of international criminal justice as they have been applied across Africa, where brutal civil conflicts in recent decades resulted in varying degrees of global attention and action. Written in an accessible style, the book explores the connections between politics and the doctrine of international criminal law. Highlighting little-known institutional examples and under-discussed political situations, the book contributes to a broader international understanding of African politics and international criminal justice, and the lessons African experiences can offer to other countries. This book is part of the Insights series. Praise for The Justice Laboratory Integrating legal and political analysis, Kerstin Bree Carlson provides a highly accessible and provocative examination of the promises and pitfalls of seeking accountability in a range of contemporary international criminal justice interventions in Africa.

David Lammy MP, shadow secretary of state for foreign, commonwealth and development affairs, outlines Labour’s plan for UK foreign policy if elected to government. He addresses the UK’s strengths and opportunities in a world that has become more divided, more dangerous, and more unpredictable. He also offers a critique of the current UK government’s approach to foreign policy, particularly at strained relationships with allies and Britain’s economic woes. The shadow foreign secretary explores the following key questions: What would a future Labour government do to modernize Britain’s diplomacy and rebuild alliances to improve Britain’s global influence? In a new age of warfare in Europe, how would Labour pursue security cooperation with allies? How would Labour address high energy costs, energy security, and the climate crisis? As Britain’s economy falters, how can foreign policy drive prosperity at home? What is Labour’s plan for international development, following the UK government’s abandonment of the 0.7% commitment? As with all members events, questions from the audience drive the conversation. Read a transcript Full Article
lab Design, Synthesis, and Preclinical Evaluation of a High-Affinity 18F-Labeled Radioligand for Myocardial Growth Hormone Secretagogue Receptor Before and After Myocardial Infarction By jnm.snmjournals.org Published On :: 2024-10-01T04:08:08-07:00 The peptide hormone ghrelin is produced in cardiomyocytes and acts through the myocardial growth hormone secretagogue receptor (GHSR) to promote cardiomyocyte survival. Administration of ghrelin may have therapeutic effects on post–myocardial infarction (MI) outcomes. Therefore, there is a need to develop molecular imaging probes that can track the dynamics of GHSR in health and disease to better predict the effectiveness of ghrelin-based therapeutics. We designed a high-affinity GHSR ligand labeled with 18F for imaging by PET and characterized its in vivo properties in a canine model of MI. Methods: We rationally designed and radiolabeled with 18F a quinazolinone derivative ([18F]LCE470) with subnanomolar binding affinity to GHSR. We determined the sensitivity and in vivo and ex vivo specificity of [18F]LCE470 in a canine model of surgically induced MI using PET/MRI, which allowed for anatomic localization of tracer uptake and simultaneous determination of global cardiac function. Uptake of [18F]LCE470 was determined by time–activity curve and SUV analysis in 3 regions of the left ventricle—area of infarct, territory served by the left circumflex coronary artery, and remote myocardium—over a period of 1.5 y. Changes in cardiac perfusion were tracked by [13N]NH3 PET. Results: The receptor binding affinity of LCE470 was measured at 0.33 nM, the highest known receptor binding affinity for a radiolabeled GHSR ligand. In vivo blocking studies in healthy hounds and ex vivo blocking studies in myocardial tissue showed the specificity of [18F]LCE470, and sensitivity was demonstrated by a positive correlation between tracer uptake and GHSR abundance. Post-MI changes in [18F]LCE470 uptake occurred independently of perfusion tracer distributions and changes in global cardiac function. We found that the regional distribution of [18F]LCE470 within the left ventricle diverged significantly within 1 d after MI and remained that way throughout the 1.5-y duration of the study. Conclusion: [18F]LCE470 is a high-affinity PET tracer that can detect changes in the regional distribution of myocardial GHSR after MI. In vivo PET molecular imaging of the global dynamics of GHSR may lead to improved GHSR-based therapeutics in the treatment of post-MI remodeling. Full Article
lab Molecular Imaging of p53 in Mouse Models of Cancer Using a Radiolabeled Antibody TAT Conjugate with SPECT By jnm.snmjournals.org Published On :: 2024-10-01T04:08:08-07:00 Mutations of p53 protein occur in over half of all cancers, with profound effects on tumor biology.

Methods: Anti-p53 monoclonal antibodies were conjugated to the cell-penetrating transactivator of transcription (TAT) peptide and a metal ion chelator and then radiolabeled with 111In to allow SPECT imaging. 111In-anti-p53-TAT conjugates were retained longer in cells overexpressing p53-specific than non–p53-specific 111In-mIgG (mouse IgG from murine plasma)-TAT controls, but not in null p53 cells. Results: In vivo SPECT imaging showed enhanced uptake of 111In-anti-p53-TAT, versus 111In-mIgG-TAT, in high-expression p53R175H and medium-expression wild-type p53 but not in null p53 tumor xenografts. The results were confirmed in mice bearing genetically engineered KPC mouse–derived pancreatic ductal adenocarcinoma tumors. Imaging with 111In-anti-p53-TAT was possible in KPC mice bearing spontaneous p53R172H pancreatic ductal adenocarcinoma tumors. Conclusion: We demonstrate the feasibility of noninvasive in vivo molecular imaging of p53 in tumor tissue using a radiolabeled TAT-modified monoclonal antibody. Full Article
lab Theranostic GPA33-Pretargeted Radioimmunotherapy of Human Colorectal Carcinoma with a Bivalent 177Lu-Labeled Radiohapten By jnm.snmjournals.org Published On :: 2024-10-01T04:08:08-07:00 Radiolabeled small-molecule DOTA-haptens can be combined with antitumor/anti-DOTA bispecific antibodies (BsAbs) for pretargeted radioimmunotherapy (PRIT). For optimized delivery of the theranostic - and β-emitting isotope 177Lu with DOTA-based PRIT (DOTA-PRIT), bivalent Gemini (DOTA-Bn-thiourea-PEG4-thiourea-Bn-DOTA, aka (3,6,9,12-tetraoxatetradecane-1,14-diyl)bis(DOTA-benzyl thiourea)) was developed. Methods: Gemini was synthesized by linking 2 S-2-(4-isothiocyanatobenzyl)-DOTA molecules together via a 1,14-diamino-PEG4 linker. [177Lu]Lu-Gemini was prepared with no-carrier-added 177LuCl3 to a molar-specific activity of 123 GBq/μmol and radiochemical purity of more than 99%. The specificity of BsAb-177Lu-Gemini was verified in vitro. Subsequently, we evaluated biodistribution and whole-body clearance for [177Lu]Lu-Gemini and, for comparison, our gold-standard monovalent [177Lu]Lu-S-2-(4-aminobenzyl)-DOTA ([177Lu]Lu-DOTA-Bn) in naïve (tumor-free) athymic nude mice. For our proof-of-concept system, a 3-step pretargeting approach was performed with an established DOTA-PRIT regimen (anti-GPA33/anti-DOTA IgG-scFv BsAb, a clearing agent, and [177Lu]Lu-Gemini) in mouse models. Results: Initial in vivo studies showed that [177Lu]Lu-Gemini behaved similarly to [177Lu]Lu-DOTA-Bn, with almost identical blood and whole-body clearance kinetics, as well as biodistribution and mouse kidney dosimetry. Pretargeting [177Lu]Lu-Gemini to GPA33-expressing SW1222 human colorectal xenografts was highly effective, leading to absorbed doses of [177Lu]Lu-Gemini for blood, tumor, liver, spleen, and kidneys of 3.99, 455, 6.93, 5.36, and 14.0 cGy/MBq, respectively. Tumor–to–normal tissue absorbed-dose ratios (i.e., therapeutic indices [TIs]) for the blood and kidneys were 114 and 33, respectively. In addition, we demonstrate that the use of bivalent [177Lu]Lu-Gemini in DOTA-PRIT leads to improved TIs and augmented [177Lu]Lu-Gemini tumor uptake and retention in comparison to monovalent [177Lu]Lu-DOTA-Bn. Finally, we established efficacy in SW1222 tumor-bearing mice, demonstrating that a single injection of anti-GPA33 DOTA-PRIT with 44 MBq (1.2 mCi) of [177Lu]Lu-Gemini (estimated tumor-absorbed dose, 200 Gy) induced complete responses in 5 of 5 animals and a histologic cure in 2 of 5 (40%) animals. Moreover, a significant increase in survival compared with nontreated controls was noted (maximum tolerated dose not reached). Conclusion: We have developed a bivalent DOTA-radiohapten, [177Lu]Lu-Gemini, that showed improved radiopharmacology for DOTA-PRIT application. The use of bivalent [177Lu]Lu-Gemini in DOTA-PRIT, as opposed to monovalent [177Lu]Lu-DOTA-Bn, allows curative treatments with considerably less administered 177Lu activity while still achieving high TIs for both the blood (>100) and the kidneys (>30).
