Bolton’s Attack on the International Criminal Court May Backfire

The US national security advisor’s recent threats look damaging but they may in fact strengthen support for the ICC from other states.

On 10 September, US National Security Advisor John Bolton used his first major speech since joining the White House to attack the International Criminal Court’s (ICC) potential investigation of American personnel in Afghanistan. The ‘American patriots’, as Bolton describes them, are being investigated for potential torture and ill-treatment of detainees, mostly in 2003 and 2004, during the United States-led invasion of the country.

Bolton has a long history of opposition to the ICC. Although the US signed the ICC Statute under president Bill Clinton, it was ‘unsigned’ by Bolton, then an under-secretary of state in the George W Bush administration.

And when the court first opened its doors in 2002, Bolton helped secure, in what he described on 10 September as one of his ‘proudest achievements’, around 100 bilateral agreements with other countries to prevent them from delivering US personnel to the ICC. Those agreements were often extracted under pressure, with the US threatening to cut off military and other aid to countries that refused to sign.

In recent years under the Obama administration, relations between the US and the ICC improved, and the US offered help and support to the court. Bolton’s attack is aimed at reversing those gains – with measures aimed directly at the court and its staff.

These include: (i) negotiating ‘even more binding, bilateral agreements to prohibit nations from surrendering US persons to the ICC’; (ii) banning ICC judges and prosecutors from entering the US, sanctioning their funds in the US financial system and prosecuting them in the US criminal courts (and doing the ‘same for any company or state that assists an ICC investigation of Americans’); and (iii) ‘taking note if any countries cooperate with ICC investigations of the United States and its allies, and remember[ing] that cooperation when setting US foreign assistance, military assistance and intelligence sharing levels’.

These are serious threats – they would potentially undermine the work of a court that is designed to prosecute the world’s worst crimes. The ICC prosecutor and its judges would be barred entry from the US to attend to vital work of the court.

Some of that work, ironically, is at the behest of the US. For instance, two of the UN Security Council’s referrals to the ICC, one in relation to atrocities committed in Sudan, the other in respect of the crimes committed by Muammar Gaddafi in Libya, were referred with US support. 

Also, the meetings of the ICC Assembly of States Parties are held each year at UN headquarters in New York. Those meetings may have to be held elsewhere if the ICC judges and staff are under threat of arrest.

In the case of the potential torture linked to operations in Afghanistan, the ICC has not been acting on its own initiative in investigating. For example, the Center for Constitutional Rights submitted ‘victim’s representations’ to the ICC on behalf of two of their clients, Sharqawi Al Hajj and Guled Hassan Duran, emphasizing the importance of an ICC investigation of US officials for serious crimes arising out of post-9/11 detention and interrogations.

According to the center, both Al Hajj and Duran were detained by the CIA in black sites or 'proxy-detention' by other countries, tormented and tortured.

Although the US is not a party to the ICC Statute, Afghanistan is, and therefore the court has jurisdiction over US nationals who allegedly committed atrocities in Afghanistan. And it should be noted that the investigation includes pursuing any atrocities committed by the Taliban and Afghan security forces during the same period.

So the basis for attacking the work of the ICC based on this is shaky, and Bolton’s threats raise a number of important international law questions going forward. 

For one, they may be unlawful retaliatory steps, given that the US has obligations to accord at least some privileges and immunities to judges and other personnel of the ICC under the 1947 UN Headquarters Agreement between the UN and US. Counter-measures might be considered by member states of the ICC, either alone, or collectively. 

In this regard, Bolton’s comments about the EU will not go unnoticed: he suggests Europe is a region where ‘the global governance dogma is strong’. The US may yet come to learn just how strong that ‘dogma’ is.

With US abstention from the ICC, the opening remains for Europe and other regions to position themselves at the heart of the international criminal justice regime, thereby – as in response to the US attitude towards climate change – building a network of partnerships with other like-minded nations to compensate for US disengagement.

Further, while the ICC has many critics, and could be improved as an institution, Bolton’s speech may have the effect of galvanizing support for the world’s first permanent international criminal court. That could be a good thing for the court, which is sorely in need of support for its work.

Whatever concerns states may have about the ICC, they may be outweighed by a mutual desire to stand up to perceived bullying by the Trump administration, in favour of the international rule of law.

Local Pathways Towards De-escalation of Libya's Conflict

A shaky truce remains broadly in place among rival Libyan forces fighting for control of Tripoli. However, a durable ceasefire to bring an end to the current bout of conflict, which was initiated by Khalifa Haftar’s Libyan Arab Armed Forces’ (LAAF) offensive on the capital in April 2019, has not been reached. In recent weeks attention has focused on talks hosted in Moscow and Berlin, with the former aimed at agreeing a ceasefire and the latter seeking to reach agreement among international actors to bring an end to external military support for Libyan warring actors, and to craft a way forward for future intra-Libyan talks. Yet, there has been little emphasis on Libyan actors – beyond Haftar and prime minister Fayez al-Serraj – in this process.
 
This roundtable will bring together experts and policymakers to discuss means of de-escalating the conflict and seeking a lasting resolution through the development of interconnected intra-Libyan social and security negotiation tracks. Mr Usama Otman Essed of the Libya Center for Strategic and Future Studies (LCSFS) will present his research group’s ideas on these issues and discuss their ongoing efforts to promote dialogue among social and security actors.

Prospects for Reforming Libya’s Economic Governance: Ways Forward

There is a broad consensus that Libya’s rentier, patronage-based system of governance is a driver, and not only a symptom, of Libya’s continuing conflict. The dysfunction of Libya’s economic system of governance has been exacerbated by the governance split that has prevailed since 2014 whereby rival administrations of state institutions have emerged. Despite these challenges, a system of economic interdependence, whereby forces aligned with Field Marshal Haftar control much of the oil and gas infrastructure and the UN-backed Government of National Accord controls the means of financial distribution, has largely prevailed. Yet, at the time of writing, this is under threat: a damaging oil blockade is being implemented by forces aligned with Haftar and those state institutions that do function on a national basis are finding it increasingly difficult to avoid being dragged into the conflict.

This roundtable will bring together analysts and policymakers to discuss these dynamics and look at possible remedies. Jason Pack, non-resident fellow at the Middle East Institute, will present the findings of his latest paper on the issue which recommends the formation of 'a Libyan-requested and Libyan-led International Financial Commission vested with the requisite authorities to completely restructure the economy.' Tim Eaton, who has been leading Chatham House’s work on Libya’s conflict economy, supporting UNSMIL’s efforts in this field, will act as respondent.

Lebanon Is Paying the Cost of Its Dysfunctional Politics

A series of fights to political stalemate have led its economy to the brink and cut it off from its natural economic partners in the Gulf.

To understand Lebanon’s financial collapse, look to its politics.

The country has been deeply damaged by an increasingly dysfunctional political system. A series of compromises have alienated it from its main markets in the Gulf and strangled its economy; anyone that has glanced at fluctuations in Lebanese bank deposits over the last 10 years can see the correlation.

Imagine if Boris Johnson or Donald Trump were obliged to form joint governments with Jeremy Corbyn or Bernie Sanders. The result would be paralysis and lack of accountability as each party pulls the country in opposite directions and blames the other for the state of limbo. This has been the state of affairs in Lebanon since the Doha agreement of 2008. 

That agreement followed an 18-month siege that paralyzed Beirut and an attack on the city by Hezbollah’s ‘black shirts’. The Doha formula imposed governments of national unity between Prime Minister Saad Hariri’s pro-Saudi camp and Hezbollah’s pro-Iran camp and their respective internal allies.

The pattern was set: each period of subsequent paralysis was followed by further compromise as the tug of war pulled the country away from its principal economic partners, the Arab Gulf states, with the regional balance of power tilting towards Hezbollah. 

It was not supposed to be like this. The Baabda Declaration in June 2012, reached after a process of national dialogue, was meant to secure Lebanon’s neutrality in regional conflicts, with both sides promising to hold back on external alliances and coexist despite difference over major regional issues like the war in Syria, the standoff between the US and Iran or relations with Israel or the Gulf states.

This has worn away. The Baabda declaration itself became a sham when Hezbollah inserted itself into the war in Syria in support of the Assad regime and overtly got involved in Iraq and Yemen as an Iranian proxy. This was followed by Saudi opposition to concessions by Hariri that led to the election of General Michel Aoun, an ally of Hezbollah, as president in October 2016; again, after a political paralysis that lasted 29 months with no active government and no head of state.  

The Saudis were also furious when President Aoun’s son-in-law, Foreign Minister Gebran Bassil, abstained from condemning the burning of the Saudi embassy in Tehran at an Arab League meeting in Cairo in January 2016, citing the need to preserve national unity.

Fearing that he was simply providing Hezbollah with protection in the guise of compromise, the Saudis pressured Hariri to resign in November 2017 during a trip to Riyadh, but he later challenged that by retracting on his resignation when back in Beirut. Lebanon was caught between two sides, and as the regional conflict intensified from tension to open confrontation, neutrality was no longer an option.

Gulf connections

An estimated 350,000 Lebanese expats live and work in Saudi Arabia, the UAE, Qatar and Kuwait. These countries are also the main clients for Lebanese contractors, consultants and advertising companies, some of which have offices there. The domestic tourism industry relies heavily on Arab Gulf visitors and they are a principal source of foreign investments especially in the real estate sector.

Lebanon also enjoyed a certain degree of political and economic protection from the US and the Gulf, and Hezbollah benefited indirectly from that protection, as it also shielded it to a certain degree from sanctions.

The deterioration of relations meant that the country was cut off by its Gulf partners. This was manifested in travel bans for Gulf Cooperation Council (GCC) nationals to Lebanon and a decrease in investments and bank deposits, as well as a decrease in remittances from Lebanese expats, partly because of economic crisis in the Gulf countries themselves.

Saudi Arabia withdrew $4 billion of aid to the Lebanese army and internal security forces, and no aid or deposits were forthcoming as the economic and financial situation deteriorated. 

The costs to the Lebanese economy include the opportunity cost created by the annual threat of war with Israel, after which trips are cancelled and projects postponed. Hezbollah also controls a section of Beirut port where it pays no duty or taxes. Add to that the economic fallout from the war in Syria, such as the impact on exports, the inflow of refugees and the cost of Hezbollah’s involvement.

The burden of these political factors is difficult to estimate but it constitutes the ransom that the Lebanese economy bears as a cost of the compromise. This is not to absolve Lebanese politicians from corruption or bankers of mismanagement but to add that political factors cannot be ignored.

The cumulative cost and economic impact of being cut off from its main economic partner eventually bankrupted the country. The fiscal and financial aspects, with Lebanon’s inability to service its debt, are but a reflection of these political factors. In the long run, the key to avoiding complete collapse is to restore relations with the GCC and free Lebanon from that very costly grip.

PARP-1-targeted Auger emitters display high-LET cytotoxic properties in vitro but show limited therapeutic utility in solid tumor models of human neuroblastoma

By jnm.snmjournals.org
Published On :: 2019-11-01T13:36:37-07:00

The currently available therapeutic radiopharmaceutical for high-risk neuroblastoma, 131I-MIBG, is ineffective at targeting micrometastases due to the low linear energy transfer (LET) properties of high-energy beta particles. In contrast, Auger radiation has high-LET properties with nanometer ranges in tissue, efficiently causing DNA damage when emitted in close proximity to DNA. The aim of this study was to evaluate the cytotoxicity of targeted Auger therapy in pre-clinical models of high-risk neuroblastoma. Methods: Using a radiolabeled poly(ADP-ribose) polymerase (PARP) inhibitor, 125I-KX1, we delivered an Auger emitter iodine-125 to PARP-1: a chromatin-binding enzyme overexpressed in neuroblastoma. In vitro cytotoxicity of 125I-KX1 was assessed in nineteen neuroblastoma cell lines, followed by in-depth pharmacological analysis in a sensitive and resistant pair of cell lines. Immunofluorescence microscopy was used to characterize 125I-KX1-induced DNA damage. Finally, in vitro/in vivo microdosimetry was modeled from experimentally derived pharmacological variables. Results: 125I-KX1 was highly cytotoxic in vitro across a panel of neuroblastoma cell lines, directly causing double strand DNA breaks. Based on subcellular dosimetry, 125I-KX1 was approximately twice as effective compared to 131I-KX1, whereas cytoplasmic 125I-MIBG demonstrated low biological effectiveness. Despite the ability to deliver focused radiation dose to the cell nuclei, 125I-KX1 remained less effective than its alpha-emitting analog 211At-MM4, and required significantly higher activity for equivalent in vivo efficacy based on tumor microdosimetry. Conclusion: Chromatin-targeted Auger therapy is lethal to high-risk neuroblastoma cells with potential use in micrometastatic disease. This study provides the first evidence for cellular lethality from a PARP-1 targeted Auger emitter, calling for further investigation into targeted Auger therapy.

High Resolution Depth-Encoding PET Detector Module with Prismatoid Light Guide Array

By jnm.snmjournals.org
Published On :: 2020-02-28T13:52:17-08:00

Depth-encoding detectors with single-ended readout provide a practical, cost-effective approach for constructing high resolution and high sensitivity PET scanners. However, the current iteration of such detectors utilizes a uniform glass light guide to achieve depth-encoding, resulting in non-uniform performance throughout the detector array due to suboptimal intercrystal light sharing. We introduce Prism-PET, a single-ended readout PET detector module with a segmented light guide composed of an array of prismatoids that introduces enhanced, deterministic light sharing. Methods: High resolution PET detector modules were fabricated with single-ended readout of polished multicrystal lutetium yttrium orthosilicate (LYSO) scintillator arrays directly coupled 4-to-1 and 9-to-1 to arrays of 3.2 x 3.2 mm2 silicon photomultiplier pixels. Each scintillator array was coupled at the non-readout side to a light guide (one 4-to-1 module with a uniform glass light guide, one 4-to-1 Prism-PET module and one 9-to-1 Prism-PET module) to introduce intercrystal light sharing, which closely mimics the behavior of dual-ended readout with the additional benefit of improved crystal identification. Flood histogram data was acquired using a 3 MBq Na-22 source to characterize crystal identification and energy resolution. Lead collimation was used to acquire data at specific depths to determine depth-of-interaction (DOI) resolution. Results: The flood histogram measurements showed excellent and uniform crystal separation throughout the Prism-PET modules while the uniform glass light guide module had performance degradation at the edges and corners. A DOI resolution of 5.0 mm full width at half maximum (FWHM) and energy resolution of 13% were obtained in the uniform glass light guide module. By comparison, the 4-to-1 coupled Prism-PET module achieved 2.5 mm FWHM DOI resolution and 9% energy resolution. Conclusion: PET scanners based on our Prism-PET modules with segmented prismatoid light guide arrays can achieve high and uniform spatial resolution (9-to-1 coupling with ~ 1 mm crystals), high sensitivity, good energy and timing resolutions (using polished crystals and after applying DOI-correction), and compact size (depth-encoding eliminates parallax error and permits smaller ring-diameter).

Guidance Document: Validation of a High-Performance Liquid Chromatography-Tandem Mass Spectrometry Immunopeptidomics Assay for the Identification of HLA Class I Ligands Suitable for Pharmaceutical Therapies [Commentary]

By feedproxy.google.com
Published On :: 2020-03-01T00:05:26-08:00

For more than two decades naturally presented, human leukocyte antigen (HLA)-restricted peptides (immunopeptidome) have been eluted and sequenced using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Since, identified disease-associated HLA ligands have been characterized and evaluated as potential active substances. Treatments based on HLA-presented peptides have shown promising results in clinical application as personalized T cell-based immunotherapy. Peptide vaccination cocktails are produced as investigational medicinal products under GMP conditions. To support clinical trials based on HLA-presented tumor-associated antigens, in this study the sensitive LC-MS/MS HLA class I antigen identification pipeline was fully validated for our technical equipment according to the current US Food and Drug Administration (FDA) and European Medicines Agency (EMA) guidelines.

The immunopeptidomes of JY cells with or without spiked-in, isotope labeled peptides, of peripheral blood mononuclear cells of healthy volunteers as well as a chronic lymphocytic leukemia and a bladder cancer sample were reliably identified using a data-dependent acquisition method. As the LC-MS/MS pipeline is used for identification purposes, the validation parameters include accuracy, precision, specificity, limit of detection and robustness.

Integrative Metabolic Pathway Analysis Reveals Novel Therapeutic Targets in Osteoarthritis [Research]

By feedproxy.google.com
Published On :: 2020-04-01T00:05:32-07:00

In osteoarthritis (OA), impairment of cartilage regeneration can be related to a defective chondrogenic differentiation of mesenchymal stromal cells (MSCs). Therefore, understanding the proteomic- and metabolomic-associated molecular events during the chondrogenesis of MSCs could provide alternative targets for therapeutic intervention. Here, a SILAC-based proteomic analysis identified 43 proteins related with metabolic pathways whose abundance was significantly altered during the chondrogenesis of OA human bone marrow MSCs (hBMSCs). Then, the level and distribution of metabolites was analyzed in these cells and healthy controls by matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI), leading to the recognition of characteristic metabolomic profiles at the early stages of differentiation. Finally, integrative pathway analysis showed that UDP-glucuronic acid synthesis and amino sugar metabolism were downregulated in OA hBMSCs during chondrogenesis compared with healthy cells. Alterations in these metabolic pathways may disturb the production of hyaluronic acid (HA) and other relevant cartilage extracellular matrix (ECM) components. This work provides a novel integrative insight into the molecular alterations of osteoarthritic MSCs and potential therapeutic targets for OA drug development through the enhancement of chondrogenesis.

The Secretome Profiling of a Pediatric Airway Epithelium Infected with hRSV Identified Aberrant Apical/Basolateral Trafficking and Novel Immune Modulating (CXCL6, CXCL16, CSF3) and Antiviral (CEACAM1) Proteins [Research]

By feedproxy.google.com
Published On :: 2020-05-01T00:05:26-07:00

The respiratory epithelium comprises polarized cells at the interface between the environment and airway tissues. Polarized apical and basolateral protein secretions are a feature of airway epithelium homeostasis. Human respiratory syncytial virus (hRSV) is a major human pathogen that primarily targets the respiratory epithelium. However, the consequences of hRSV infection on epithelium secretome polarity and content remain poorly understood. To investigate the hRSV-associated apical and basolateral secretomes, a proteomics approach was combined with an ex vivo pediatric human airway epithelial (HAE) model of hRSV infection (data are available via ProteomeXchange and can be accessed at https://www.ebi.ac.uk/pride/ with identifier PXD013661). Following infection, a skewing of apical/basolateral abundance ratios was identified for several individual proteins. Novel modulators of neutrophil and lymphocyte activation (CXCL6, CSF3, SECTM1 or CXCL16), and antiviral proteins (BST2 or CEACAM1) were detected in infected, but not in uninfected cultures. Importantly, CXCL6, CXCL16, CSF3 were also detected in nasopharyngeal aspirates (NPA) from hRSV-infected infants but not healthy controls. Furthermore, the antiviral activity of CEACAM1 against RSV was confirmed in vitro using BEAS-2B cells. hRSV infection disrupted the polarity of the pediatric respiratory epithelial secretome and was associated with immune modulating proteins (CXCL6, CXCL16, CSF3) never linked with this virus before. In addition, the antiviral activity of CEACAM1 against hRSV had also never been previously characterized. This study, therefore, provides novel insights into RSV pathogenesis and endogenous antiviral responses in pediatric airway epithelium.

Decreased Immunoglobulin G Core Fucosylation, A Player in Antibody-dependent Cell-mediated Cytotoxicity, is Associated with Autoimmune Thyroid Diseases [Research]

By feedproxy.google.com
Published On :: 2020-05-01T00:05:26-07:00

Autoimmune thyroid diseases (AITD) are the most common group of autoimmune diseases, associated with lymphocyte infiltration and the production of thyroid autoantibodies, like thyroid peroxidase antibodies (TPOAb), in the thyroid gland. Immunoglobulins and cell-surface receptors are glycoproteins with distinctive glycosylation patterns that play a structural role in maintaining and modulating their functions. We investigated associations of total circulating IgG and peripheral blood mononuclear cells glycosylation with AITD and the influence of genetic background in a case-control study with several independent cohorts and over 3,000 individuals in total. The study revealed an inverse association of IgG core fucosylation with TPOAb and AITD, as well as decreased peripheral blood mononuclear cells antennary α1,2 fucosylation in AITD, but no shared genetic variance between AITD and glycosylation. These data suggest that the decreased level of IgG core fucosylation is a risk factor for AITD that promotes antibody-dependent cell-mediated cytotoxicity previously associated with TPOAb levels.

The peroxisome is a subcellular organelle that functions in essential metabolic pathways, including biosynthesis of plasmalogens, fatty acid β-oxidation of very-long-chain fatty acids, and degradation of hydrogen peroxide. Peroxisome biogenesis disorders (PBDs) manifest as severe dysfunction in multiple organs, including the central nervous system (CNS), but the pathogenic mechanisms in PBDs are largely unknown. Because CNS integrity is coordinately established and maintained by neural cell interactions, we here investigated whether cell-cell communication is impaired and responsible for the neurological defects associated with PBDs. Results from a noncontact co-culture system consisting of primary hippocampal neurons with glial cells revealed that a peroxisome-deficient astrocytic cell line secretes increased levels of brain-derived neurotrophic factor (BDNF), resulting in axonal branching of the neurons. Of note, the BDNF expression in astrocytes was not affected by defects in plasmalogen biosynthesis and peroxisomal fatty acid β-oxidation in the astrocytes. Instead, we found that cytosolic reductive states caused by a mislocalized catalase in the peroxisome-deficient cells induce the elevation in BDNF secretion. Our results suggest that peroxisome deficiency dysregulates neuronal axogenesis by causing a cytosolic reductive state in astrocytes. We conclude that astrocytic peroxisomes regulate BDNF expression and thereby support neuronal integrity and function.

Targeting the polyamine pathway—“a means” to overcome chemoresistance in triple-negative breast cancer [Cell Biology]

By feedproxy.google.com
Published On :: 2020-05-08T03:41:14-07:00

Triple-negative breast cancer (TNBC) is characterized by its aggressive biology, early metastatic spread, and poor survival outcomes. TNBC lacks expression of the targetable receptors found in other breast cancer subtypes, mandating use of cytotoxic chemotherapy. However, resistance to chemotherapy is a significant problem, encountered in about two-thirds of TNBC patients, and new strategies are needed to mitigate resistance. In this issue of the Journal of Biological Chemistry, Geck et al. report that TNBC cells are highly sensitive to inhibition of the de novo polyamine synthesis pathway and that inhibition of this pathway sensitizes cells to TNBC-relevant chemotherapy, uncovering new opportunities for addressing chemoresistance.

The everyday practices of global finance: gender and regulatory politics of ‘diversity’

By feedproxy.google.com
Published On :: Wed, 06 Nov 2019 08:39:23 +0000

6 November 2019 , Volume 95, Number 6

This article argues that practices of global finance provide a rich opportunity to consider gender's embodiment in everyday, but highly regulatory, financial life. Tracing a pathway through the rise of the ‘diversity agenda’ in global finance in the wake of the global financial crisis, the article asks how ‘diversity’ has shaped the global financial services industry, and whether it has challenged the reproduction of gendered power in global finance. Recent, innovative feminist political economy work has laid out a clear challenge to researchers of the global political economy to explore how everyday practices have become significant sites of gendered, regulatory power, and this article takes up this challenge, analysing how the rise of ‘diversity’ in financial services reveals the crucial intersections of gendered power and everyday economic practices. Using a conceptual framework drawn explicitly from Marysia Zalewski's work, this article advances critical inquiry into how gender has become an often unacknowledged way of writing the world of global finance, in ongoing, and problematic, ways. It proposes that the practices and futures of the diversity agenda in global finance provide a window into the persistent failure of global finance to reconfigure its foundational masculinism, and asks that financial actors begin to take seriously the foundational, gendered myths on which global finance has been built.
