Fundamental cellular properties are determined by the repertoire and abundance of proteins displayed on the cell surface. As such, the trafficking mechanisms for establishing and maintaining the surface proteome must be tightly regulated for cells to respond appropriately to extracellular cues, yet plastic enough to adapt to ever-changing environments. Not only are the identity and abundance of surface proteins critical, but in many cases, their regulated spatial positioning within surface nanodomains can greatly impact their function. In the context of neuronal cell biology, surface levels and positioning of ion channels and neurotransmitter receptors play essential roles in establishing important properties, including cellular excitability and synaptic strength. Here we review our current understanding of the trafficking pathways that control the abundance and localization of proteins important for synaptic function and plasticity, as well as recent technological advances that are allowing the field to investigate protein trafficking with increasing spatiotemporal precision.

Alterations and mutations of endo-lysosomal trafficking proteins have been associated with cancer progression. Identification and characterization of endo-lysosomal trafficking proteins in invasive cholangiocarcinoma (CCA) cells may benefit prognosis and drug design for CCA. To identify and characterize endo-lysosomal trafficking proteins in invasive CCA. A lysosomal-enriched fraction was isolated from a TNF-α induced invasive CCA cell line (KKU-100) and uninduced control cells and protein identification was performed with nano-LC MS/MS. Novel lysosomal proteins that were upregulated in invasive CCA cells were validated by real-time RT-PCR. We selected Rab7 for further studies of protein level using western blotting and subcellular localization using immunofluorescence. The role of Rab7 in CCA invasion was determined by siRNA gene knockdown and matrigel transwell assay. Rab7 mRNA and protein were upregulated in invasive CCA cells compared with non-treated controls. Immunofluorescence studies demonstrated that Rab7 was expressed predominantly in invasive CCA cells and was localized in the cytoplasm and lysosomes. Suppression of Rab7 translation significantly inhibited TNF-α-induced cell invasion compared to non-treated control (p= 0.044). Overexpression of Rab7 in CCA cells was associated with cell invasion, supporting Rab7 as a novel candidate for the development of diagnostic and therapeutic strategies for CCA.

Economics of human trafficking.

Because freedom of choice and economic gain are at the heart of productivity, human trafficking impedes national and international economic growth. Within the next 10 years, crime experts expect human trafficking to surpass drug and arms trafficking in its incidence, cost to human well-being, and profitability to criminals (Schauer and Wheaton, 2006: 164-165). The loss of agency from human trafficking as well as from modern slavery is the result of human vulnerability (Bales, 2000: 15). As people become vulnerable to exploitation and businesses continually seek the lowest-cost labour sources, trafficking human beings generates profit and a market for human trafficking is created. This paper presents an economic model of human trafficking that encompasses all known economic factors that affect human trafficking both across and within national borders. We envision human trafficking as a monopolistically competitive industry in which traffickers act as intermediaries between vulnerable individuals and employers by supplying differentiated products to employers. In the human trafficking market, the consumers are employers of trafficked labour and the products are human beings. Using a rational-choice framework of human trafficking we explain the social situations that shape relocation and working decisions of vulnerable populations leading to human trafficking, the impetus for being a trafficker, and the decisions by employers of trafficked individuals. The goal of this paper is to provide a common ground upon which policymakers and researchers can collaborate to decrease the incidence of trafficking in humans.

HUMAN TRAFFICKING DRUG TRAFFICKING, AND THE DEATH PENALTY

Full Text Available Both Australia and Indonesia have made commitments to combatting human trafficking.  Through the experience of Mary Jane Veloso it can be seen that it is most often the vulnerable ‘mule’ that is apprehended by law enforcement and not the powerful leaders of crime syndicates. It is unacceptable that those vulnerable individuals may face execution for acts committed under threat of force, coercion, fraud, deception or abuse of power. For this reason it is vital that a system of victim identification is developed, including better training for law enforcement, legal representatives and members of the judiciary. This paper builds on submissions by authors for Australian Parliamentary Inquiry into Human Trafficking, and focusses on issues arising in the complex cross section of human trafficking, drug trafficking, and the death penalty with particular attention on identifying victims and effective reporting mechanisms in both Australia and Indonesia. It concludes that, in the context of human trafficking both countries could make three main improvements to law and policy, among others, 1 enactment of laws that create clear mandatory protection for human trafficking victims; 2 enactment of criminal laws that provides complete defence for victim of human trafficking; 3 enactment of corporate reporting mechanisms. Systemic protection and support is not sufficiently available without clear legislative protection as this paper suggests together with standardised referral mechanisms and effective financial reporting mechanisms. The implementation can be achieved through collaborative responses and inter-agency coordination with data collection and properly trained specialists.

Sjögren's syndrome (SjS) is a chronic autoimmune disease that mainly targets the salivary and lacrimal glands. It has been controversial whether anti-muscarinic type 3 receptor (α-M3R) autoantibodies in patients with SjS inhibit intracellular trafficking of aquaporin-5 (AQP5), water transport protein, leading to secretory dysfunction. To address this issue, GFP-tagged human AQP5 was overexpressed in human salivary gland cells (HSG-hAQP5) and monitored AQP5 trafficking to the plasma membrane following carbachol (CCh, M3R agonist) stimulation. AQP5 trafficking was indeed mediated by M3R stimulation, shown in partial blockage of trafficking by M3R-antagonist 4-DAMP. HSG-hAQP5 pre-incubated with SjS plasma for 24 hours significantly reduced AQP5 trafficking with CCh, compared with HSG-hAQP5 pre-incubated with healthy control (HC) plasma. This inhibition was confirmed by monoclonal α-M3R antibody and pre-absorbed plasma. Interestingly, HSG-hAQP5 pre-incubated with SjS plasma showed no change in cell volume, compared to the cells incubated with HC plasma showing shrinkage by twenty percent after CCh-stimulation. Our findings clearly indicate that binding of anti-M3R autoantibodies to the receptor, which was verified by immunoprecipitation, suppresses AQP5 trafficking to the membrane and contribute to impaired fluid secretion in SjS. Our current study urges further investigations of clinical associations between SjS symptoms, such as degree of secretory dysfunction, cognitive impairment, and/or bladder irritation, and different profiles (titers, isotypes, and/or specificity) of anti-M3R autoantibodies in individuals with SjS.

2016-07-01

Full Text Available AbstractThere is emerging evidence that exocytosis plays an important role in regulating T cell receptor (TCR signaling. The trafficking molecules involved in lytic granule (LG secretion in cytotoxic T lymphocytes (CTL have been well studied due to the immune disorder known as familial hemophagocytic lymphohisiocytosis (FHLH. However, the knowledge of trafficking machineries regulating the exocytosis of receptors and signaling molecules remains quite limited. In this review, we summarize the reported trafficking molecules involved in the transport of the TCR and downstream signaling molecules to the cell surface. By combining this information with the known knowledge of LG exocytosis and general exocytic trafficking machinery, we attempt to draw a more complete picture of how the TCR signaling network and exocytic trafficking matrix are interconnected to facilitate T cell activation. This also highlights how membrane compartmentalization facilitates the spatiotemporal organization of cellular responses that are essential for immune functions.

Rebooting Trafficking

Full Text Available While popular psychology and appeals to emotion have unfortunately dominated discussions of ‘sex trafficking’, this article suggests that feminist psychoanalytic film theory and theories of affect are still useful for making sense of the appeal of sensational exposés like Lifetime Television’s Human Trafficking (2005. The dynamic of identification with (and impersonation of a human trafficking ‘victim’ by the rescuing Immigration and Customs Enforcement agent (Mira Sorvino is particularly worthy of scrutiny. Film theory about the ‘rebooting’ of film franchises (iconic brands like Batman also helps explain the preponderance of similar programming—Sex Slaves (2005, Selling the Girl Next Door (2011, Trafficked (2016—and the way contemporary discourses of human trafficking have effectively rebranded the myth of ‘white slavery’.

Role of LRRK2 in the regulation of dopamine receptor trafficking.

Directory of Open Access Journals (Sweden)

Mauro Rassu

Full Text Available Mutations in LRRK2 play a critical role in both familial and sporadic Parkinson's disease (PD. Up to date, the role of LRRK2 in PD onset and progression remains largely unknown. However, experimental evidence highlights a critical role of LRRK2 in the control of vesicle trafficking that in turn may regulate different aspects of neuronal physiology. We have analyzed the role of LRRK2 in regulating dopamine receptor D1 (DRD1 and D2 (DRD2 trafficking. DRD1 and DRD2 are the most abundant dopamine receptors in the brain. They differ in structural, pharmacological and biochemical properties, as well as in localization and internalization mechanisms. Our results indicate that disease-associated mutant G2019S LRRK2 impairs DRD1 internalization, leading to an alteration in signal transduction. Moreover, the mutant forms of LRRK2 affect receptor turnover by decreasing the rate of DRD2 trafficking from the Golgi complex to the cell membrane. Collectively, our findings are consistent with the conclusion that LRRK2 influences the motility of neuronal vesicles and the neuronal receptor trafficking. These findings have important implications for the complex role that LRRK2 plays in neuronal physiology and the possible pathological mechanisms that may lead to neuronal death in PD.

SLC6A3 coding variant Ala559Val found in two autism probands alters dopamine transporter function and trafficking.

Emerging evidence associates dysfunction in the dopamine (DA) transporter (DAT) with the pathophysiology of autism spectrum disorder (ASD). The human DAT (hDAT; SLC6A3) rare variant with an Ala to Val substitution at amino acid 559 (hDAT A559V) was previously reported in individuals with bipolar disorder or attention-deficit hyperactivity disorder (ADHD). We have demonstrated that this variant is hyper-phosphorylated at the amino (N)-terminal serine (Ser) residues and promotes an anomalous DA efflux phenotype. Here, we report the novel identification of hDAT A559V in two unrelated ASD subjects and provide the first mechanistic description of its impaired trafficking phenotype. DAT surface expression is dynamically regulated by DAT substrates including the psychostimulant amphetamine (AMPH), which causes hDAT trafficking away from the plasma membrane. The integrity of DAT trafficking directly impacts DA transport capacity and therefore dopaminergic neurotransmission. Here, we show that hDAT A559V is resistant to AMPH-induced cell surface redistribution. This unique trafficking phenotype is conferred by altered protein kinase C β (PKCβ) activity. Cells expressing hDAT A559V exhibit constitutively elevated PKCβ activity, inhibition of which restores the AMPH-induced hDAT A559V membrane redistribution. Mechanistically, we link the inability of hDAT A559V to traffic in response to AMPH to the phosphorylation of the five most distal DAT N-terminal Ser. Mutation of these N-terminal Ser to Ala restores AMPH-induced trafficking. Furthermore, hDAT A559V has a diminished ability to transport AMPH, and therefore lacks AMPH-induced DA efflux. Pharmacological inhibition of PKCβ or Ser to Ala substitution in the hDAT A559V background restores AMPH-induced DA efflux while promoting intracellular AMPH accumulation. Although hDAT A559V is a rare variant, it has been found in multiple probands with neuropsychiatric disorders associated with imbalances in DA neurotransmission

Sinai Trafficking: Origin and Definition of a New Form of Human Trafficking

Directory of Open Access Journals (Sweden)

Mirjam van Reisen

2015-02-01

Full Text Available The phenomenon that is coined “Sinai Trafficking” started in 2009 in the Sinai desert. It involves the abduction, extortion, sale, torture, sexual violation and killing of men, women and children. Migrants, of whom the vast majority are from Eritrean descent, are abducted and brought to the Sinai desert, where they are sold and resold, extorted for very high ransoms collected by mobile phone, while being brutally and “functionally” tortured to support the extortion. Many of them die in Sinai. Over the last five years broadcasting stations, human rights organisations and academics have reported on the practices in the Sinai and some of these reports have resulted in some confusion on the modus operandi. Based on empirical research by the authors and the analysis of data gathered in more than 200 recorded interviews with Sinai hostages and survivors on the practices, this article provides a definition of Sinai Trafficking. It argues that the term Sinai Trafficking can be used to differentiate a particular new set of criminal practices that have first been reported in the Sinai Peninsula. The article further examines how the new phenomenon of Sinai Trafficking can be framed into the legal human trafficking definition. The interconnectedness of Sinai Trafficking with slavery, torture, ransom collection, extortion, sexual violence and other severe crimes is presented to substantiate the use of the trafficking framework. The plight of Sinai survivors in Israel and Egypt is explained to illustrate the cyclical process of the trafficking practices especially endured by Eritreans, introduced as the Human Trafficking Cycle. The article concludes by setting out areas for further research.

During an inflammatory response, lymphocyte recruitment into tissue must be tightly controlled because dysregulated trafficking contributes to the pathogenesis of chronic disease. Here we show that during inflammation and in response to adiponectin, B cells tonically inhibit T cell trafficking by secreting a peptide (PEPITEM) proteolytically derived from 14.3.3 zeta delta (14.3.3.ζδ) protein. PEPITEM binds cadherin-15 on endothelial cells, promoting synthesis and release of sphingosine-1 phosphate, which inhibits trafficking of T cells without affecting recruitment of other leukocytes. Expression of adiponectin receptors on B cells and adiponectin-induced PEPITEM secretion wanes with age, implying immune senescence of the pathway. Additionally, these changes are evident in individuals with type 1 diabetes or rheumatoid arthritis, and circulating PEPITEM in patient serum is reduced compared to that of healthy age-matched donors. In both diseases, tonic inhibition of T cell trafficking across inflamed endothelium is lost. Control of patient T cell trafficking is re-established by treatment with exogenous PEPITEM. Moreover, in animal models of peritonitis, hepatic ischemia-reperfusion injury, Salmonella infection, uveitis and Sjögren's syndrome, PEPITEM reduced T cell recruitment into inflamed tissues.

The mechanisms behind the hereditary thrombocytosis induced by the thrombopoietin (THPO) receptor MPL P106L mutant remain unknown. A complete trafficking defect to the cell surface has been reported, suggesting either weak constitutive activity or nonconventional THPO-dependent mechanisms. Here, we report that the thrombocytosis phenotype induced by MPL P106L belongs to the paradoxical group, where low MPL levels on platelets and mature megakaryocytes (MKs) lead to high serum THPO levels, whereas weak but not absent MPL cell-surface localization in earlier MK progenitors allows response to THPO by signaling and amplification of the platelet lineage. MK progenitors from patients showed no spontaneous growth and responded to THPO, and MKs expressed MPL on their cell surface at low levels, whereas their platelets did not respond to THPO. Transduction of MPL P106L in CD34 + cells showed that this receptor was more efficiently localized at the cell surface on immature than on mature MKs, explaining a proliferative response to THPO of immature cells and a defect in THPO clearance in mature cells. In a retroviral mouse model performed in Mpl -/- mice, MPL P106L could induce a thrombocytosis phenotype with high circulating THPO levels. Furthermore, we could select THPO-dependent cell lines with more cell-surface MPL P106L localization that was detected by flow cytometry and [ 125 I]-THPO binding. Altogether, these results demonstrate that MPL P106L is a receptor with an incomplete defect in trafficking, which induces a low but not absent localization of the receptor on cell surface and a response to THPO in immature MK cells. © 2016 by The American Society of Hematology.

How to Use a Trafficked Woman. The Alliance between Political and Criminal Trafficking Organisations

Directory of Open Access Journals (Sweden)

John Davies

2011-03-01

Full Text Available The principal argument of this paper is that migrant women with secure mobility rights and supportive social networks can avoid or mitigate many trafficking harms. However the paper contends that some actors have conspired to prevent such circumstances so as to pursue diverse political agendas at the expense of migrant women. The paper’s analysis restructures the trafficking contest from organised criminals versus law enforcement agencies to principally a contest between migrant women and those political agents who benefit from the moral panic associated with trafficking. It is then argued that it is these more sophisticated political actors rather than organised criminals and the clients of sex workers are the most important stakeholders in sustaining or exploiting trafficking harm. Therefore, it is concluded that resolving many trafficking harms in the EEA could be achieved by subverting political traffickers through improving migration policy rather than fighting organised crime.

The prevention of illicit trafficking of nuclear and radioactive material in Vietnam

Full text: I Introduction - Vietnam has signed the Safeguard Agreement under NPT in 1989 and is preparing to join the Convention on Physical Protection of Nuclear Materials. To enhance the fulfillment of commitment, at the beginning of 1993 a joint group of experts from VAEC, Ministry of Defense and Ministry of Security was set up to: Search the current situation of illicit trafficking of nuclear and radioactive material; and Prevent the illicit trafficking. Activities were carried out during four years with modest resources and results achieved are remarkable, no case of illicit trafficking has been detected from 1997 until now. II Searching the illicit trafficking situation - The objectives of searching are the following: What is material in the illicit trafficking?; What is the motivation of illicit trafficking?; What is the illicit trafficking ploy? 1. Material in the illicit trafficking - At the end of the seventies and during the eighties, there were rumors of black trade of precious and mysterious metal with unbelievable high prices, higher many times than the gold price. Rumors said the name of the metal was uranium, black copper or osmium . We have collected all material confiscated during that time and during our activities, and the study shows: 516.56 kg of confiscated material is depleted uranium with U-235 mass content ranging from 0.2% to 0.32%, uranium mass content (U-235+U-238) ranging from 80% to 99%; Mostly pieces have a mark Made in USA. The masses of pieces range from 0.3 kg to 150 kg. By geometry and structure there are some mechanical parts of still unidentified machines; All pieces can be considered as radioactive material, the radioactive dose rate at their surface ranges from 10μSv/h to 100μSv/h. (Background: 0.2μSv/h); 268.65 kg confiscated material is false uranium made of lead. Its mark is written in very bad English trying to imitate the mark of real pieces. One false osmium body is made of silver. 2. Motivation of illicit

Nuclear functions and subcellular trafficking mechanisms of the epidermal growth factor receptor family

Science.gov (United States)

2012-01-01

Accumulating evidence suggests that various diseases, including many types of cancer, result from alteration of subcellular protein localization and compartmentalization. Therefore, it is worthwhile to expand our knowledge in subcellular trafficking of proteins, such as epidermal growth factor receptor (EGFR) and ErbB-2 of the receptor tyrosine kinases, which are highly expressed and activated in human malignancies and frequently correlated with poor prognosis. The well-characterized trafficking of cell surface EGFR is routed, via endocytosis and endosomal sorting, to either the lysosomes for degradation or back to the plasma membrane for recycling. A novel nuclear mode of EGFR signaling pathway has been gradually deciphered in which EGFR is shuttled from the cell surface to the nucleus after endocytosis, and there, it acts as a transcriptional regulator, transmits signals, and is involved in multiple biological functions, including cell proliferation, tumor progression, DNA repair and replication, and chemo- and radio-resistance. Internalized EGFR can also be transported from the cell surface to several intracellular compartments, such as the Golgi apparatus, the endoplasmic reticulum, and the mitochondria, in addition to the nucleus. In this review, we will summarize the functions of nuclear EGFR family and the potential pathways by which EGFR is trafficked from the cell surface to a variety of cellular organelles. A better understanding of the molecular mechanism of EGFR trafficking will shed light on both the receptor biology and potential therapeutic targets of anti-EGFR therapies for clinical application.

Protein A (SpA) of Staphylococcus aureus is known to target the paratope of immunoglobulins expressing V(H)3 genes, and to delete marginal zone B cells and B-1a in vivo. We have discovered that SpA endows S. aureus with the potential to subvert B-cell trafficking in the host. We found that SpA, whose Fc-binding site has been inactivated, binds essentially to naïve B cells and induces a long-lasting decrease in CXCR4 expression and in B-cell chemotaxis to CXCL12. Competition experiments indicated that SpA does not interfere with binding of CXCR4 ligands and does not directly bind to CXCR4. This conclusion is strongly supported by the inability of SpA to modulate clathrin-mediated CXCR4 internalization, which contrasts with the potent effect of anti-immunoglobin M (IgM) antibodies. Microscopy and biochemical experiments confirmed that SpA binds to the surface IgM/IgD complex and induces its clathrin-dependent internalization. Concomitantly, the SpA-induced signaling leads to protein kinase C-dependent CXCR4 downmodulation, suggesting that SpA impairs the recycling of CXCR4, a postclathrin process that leads to either degradation into lysozomes or de novo expression at the cell surface. In addition to providing novel insight into disruption of B-cell trafficking by an infectious agent, our findings may have therapeutic implications. Because CXCR4 has been associated with cancer metastasis and with certain autoimmune diseases, SpA behaves as an evolutionary tailored highly specific, chemokine receptor inhibitor that may have value in addition to conventional cytotoxic therapy in patients with various malignancies and immune-mediated diseases.

The scaling of urban surface water abundance and impairment with city size

Science.gov (United States)

Steele, M. K.

2018-03-01

Urbanization alters surface water compared to nonurban landscapes, yet little is known regarding how basic aquatic ecosystem characteristics, such as the abundance and impairment of surface water, differ with population size or regional context. This study examined the abundance, scaling, and impairment of surface water by quantifying the stream length, water body area, and impaired stream length for 3520 cities in the United States with populations from 2500 to 18 million. Stream length, water body area, and impaired stream length were quantified using the National Hydrography Dataset and the EPA's 303(d) list. These metrics were scaled with population and city area using single and piecewise power-law models and related to biophysical factors (precipitation, topography) and land cover. Results show that abundance of stream length and water body area in cities actually increases with city area; however, the per person abundance decreases with population size. Relative to population, impaired stream length did not increase until city populations were > 25,000 people, then scaled linearly with population. Some variation in abundance and impairment was explained by biophysical context and land cover. Development intensity correlated with stream density and impairment; however, those relationships depended on the orientation of the land covers. When high intensity development occupied the local elevation highs (+ 15 m) and undeveloped land the elevation lows, the percentage of impaired streams was less than the opposite land cover orientation (- 15 m) or very flat land. These results show that surface water abundance and impairment across contiguous US cities are influenced by city size and by biophysical setting interacting with land cover intensity.

South Africa – Safe Haven for Human Traffickers? Employing the Arsenal of Existing Law to Combat Human Trafficking

Full Text Available aving ratified the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, South Africa is obliged to adopt legislative measures that criminalise human trafficking and comply with other standards laid down in this international instrument. However, by mid-2011, South Africa had not enacted the required comprehensive counter-trafficking legislation. The question that now arises is if the absence of such anti-trafficking legislation poses an insurmountable obstacle to the prosecution of traffickers for trafficking-related activities. In asking this question the article examines the utilisation of existing crimes in order to prosecute and punish criminal activities committed during the human trafficking process. Firstly, a selection of existing common law and statutory crimes that may often be applicable to trafficking related activities is mapped out. Secondly, transitional trafficking provisions in the Children's Act 38 of 2005 and the Criminal Law (Sexual Offences and Related Matters Amendment Act 32 of 2007 are discussed. Finally, since the Prevention and Combating of Trafficking in Persons Bill B7 of 2010 will in all probability be enacted in the near future, the use of other criminal law provisions in human trafficking prosecutions, even after the passing of this bill into law, is reflected upon.

Despite the legislation passed in the 19th century outlawing human slavery, it is more widespread today than at the conclusion of the civil war. Modern human slavery, termed human trafficking, comes in several forms. The most common type of human trafficking is sex trafficking, the sale of women and children into prostitution. Labor trafficking is the sale of men, women, and children into hard labor for which they receive little or no compensation. Other forms of trafficking include child soldiering, war brides, and organ removal. Healthcare professionals play a critical role in both finding victims of human trafficking while they are still in captivity, as well as caring for their mental and physical needs upon release. Those working in the healthcare profession need to be educated regarding how a trafficking victim may present, as well as their unique healthcare needs.

The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

Analysis of occludin trafficking, demonstrating continuous endocytosis, degradation, recycling and biosynthetic secretory trafficking.

Full Text Available Tight junctions (TJs link adjacent cells and are critical for maintenance of apical-basolateral polarity in epithelial monolayers. The TJ protein occludin functions in disparate processes, including wound healing and Hepatitis C Virus infection. Little is known about steady-state occludin trafficking into and out of the plasma membrane. Therefore, we determined the mechanisms responsible for occludin turnover in confluent Madin-Darby canine kidney (MDCK epithelial monolayers. Using various biotin-based trafficking assays we observed continuous and rapid endocytosis of plasma membrane localised occludin (the majority internalised within 30 minutes. By 120 minutes a significant reduction in internalised occludin was observed. Inhibition of lysosomal function attenuated the reduction in occludin signal post-endocytosis and promoted co-localisation with the late endocytic system. Using a similar method we demonstrated that ∼20% of internalised occludin was transported back to the cell surface. Consistent with these findings, significant co-localisation between internalised occludin and recycling endosomal compartments was observed. We then quantified the extent to which occludin synthesis and transport to the plasma membrane contributes to plasma membrane occludin homeostasis, identifying inhibition of protein synthesis led to decreased plasma membrane localised occludin. Significant co-localisation between occludin and the biosynthetic secretory pathway was demonstrated. Thus, under steady-state conditions occludin undergoes turnover via a continuous cycle of endocytosis, recycling and degradation, with degradation compensated for by biosynthetic exocytic trafficking. We developed a mathematical model to describe the endocytosis, recycling and degradation of occludin, utilising experimental data to provide quantitative estimates for the rates of these processes.

Moreover, sustained inhibition of LRP1 levels by siRNA leads to the accumulation of PrP(C) in biosynthetic compartments, with a concomitant lowering of surface PrP(C), suggesting that LRP1 expedites the trafficking of PrP(C) to the neuronal surface. PrP(C) and LRP1 can be co......-immunoprecipitated from the endoplasmic reticulum in normal neurons. The N-terminal domain of PrP(C) binds to purified human LRP1 with nanomolar affinity, even in the presence of 1 microM of the LRP-specific chaperone, receptor-associated protein (RAP).

Vesicle-associated membrane protein 2 mediates trafficking of α5β1 integrin to the plasma membrane

International Nuclear Information System (INIS)

Hasan, Nazarul; Hu, Chuan

2010-01-01

Integrins are major receptors for cell adhesion to the extracellular matrix (ECM). As transmembrane proteins, the levels of integrins at the plasma membrane or the cell surface are ultimately determined by the balance between two vesicle trafficking events: endocytosis of integrins at the plasma membrane and exocytosis of the vesicles that transport integrins. Here, we report that vesicle-associated membrane protein 2 (VAMP2), a SNARE protein that mediates vesicle fusion with the plasma membrane, is involved in the trafficking of α5β1 integrin. VAMP2 was present on vesicles containing endocytosed β1 integrin. Small interfering RNA (siRNA) silencing of VAMP2 markedly reduced cell surface α5β1 and inhibited cell adhesion and chemotactic migration to fibronectin, the ECM ligand of α5β1, without altering cell surface expression of α2β1 integrin or α3β1 integrin. By contrast, silencing of VAMP8, another SNARE protein, had no effect on cell surface expression of the integrins or cell adhesion to fibronectin. In addition, VAMP2-mediated trafficking is involved in cell adhesion to collagen but not to laminin. Consistent with disruption of integrin functions in cell proliferation and survival, VAMP2 silencing diminished proliferation and triggered apoptosis. Collectively, these data indicate that VAMP2 mediates the trafficking of α5β1 integrin to the plasma membrane and VAMP2-dependent integrin trafficking is critical in cell adhesion, migration and survival.

Natural radionuclides have been subject to trafficking worldwide, involving natural uranium ore (U 238), processed uranium (yellow cake), low enriched uranium (20% U 235), radium (Ra 226), polonium (Po 210), and natural thorium ore (Th 232). An important prerequisite to successful illicit trafficking activities is access to a suitable logistical infrastructure enabling an undercover shipment of radioactive materials and, in case of trafficking natural uranium or thorium ore, capable of transporting large volumes of material. Covert en route diversion of an authorised uranium transport, together with covert diversion of uranium concentrate from an operating or closed uranium mines or mills, are subject of case studies. Such cases, involving Israel, Iran, Pakistan and Libya, have been analyzed in terms of international actors involved and methods deployed. Using international incident data contained in the Database on Nuclear Smuggling, Theft and Orphan Radiation Sources (DSTO) and international experience gained from the fight against drug trafficking, a generic Trafficking Pathway Model (TPM) is developed for trafficking of natural radionuclides. The TPM covers the complete trafficking cycle, ranging from material diversion, covert material transport, material concealment, and all associated operational procedures. The model subdivides the trafficking cycle into five phases: (1) Material diversion by insider(s) or initiation by outsider(s); (2) Covert transport; (3) Material brokerage; (4) Material sale; (5) Material delivery. An Action Plan is recommended, addressing the strengthening of the national infrastructure for material protection and accounting, development of higher standards of good governance, and needs for improving the control system deployed by customs, border guards and security forces.

William R. DI PIETRO

2015-12-01

Full Text Available The paper proposes that national morality is an important variable for explaining national anti-trafficking policy. It uses cross country regression analysis to see whether or not empirically national morality is a determinant of anti-trafficking policy. The findings of the paper are consistent with the notion that improved levels of national morality lead to better national anti-trafficking policy. National morality is found to be statistically relevant for national anti-trafficking policy when controlling for the extent of democracy, the share of the private sector in the economy, and the degree of globalization.

Tetraspanins comprise a large superfamily of cell surface-associated membrane proteins characterized by four transmembrane domains. They participate in a variety of cellular processes, like cell activation, adhesion, differentiation and tumour invasion. At the cell surface, tetraspanins form networks with a wide diversity of proteins called tetraspanin-enriched microdomains (TEMs). CD63 was the first characterized tetraspanin. In addition to its presence in TEMs, CD63 is also abundantly present in late endosomes and lysosomes. CD63 at the cell surface is endocytosed via a clathrin-dependent pathway, although recent studies suggest the involvement of other pathways as well and we here present evidence for a role of caveolae in CD63 endocytosis. In late endosomes, CD63 is enriched on the intraluminal vesicles, which by specialized cells are secreted as exosomes through fusion of endosomes with the plasma membrane. The complex localization pattern of CD63 suggests that its intracellular trafficking and distribution must be tightly regulated. In this review we discuss the latest insights in CD63 trafficking and its emerging function as a transport regulator of its interaction partners. Finally, the involvement of CD63 in cancer will be discussed.

Objectives (1) To estimate the proportion of National Health Service (NHS) professionals who have come into contact with trafficked people and (2) to measure NHS professionals’ knowledge and confidence to respond to human trafficking. Design A cross-sectional survey. Setting Face-to-face mandatory child protection and/or vulnerable adults training sessions at 10 secondary healthcare provider organisations in England, and meetings of the UK College of Emergency Medicine. Participants 782/892 (84.4%) NHS professionals participated, including from emergency medicine, maternity, mental health, paediatrics and other clinical disciplines. Measures Self-completed questionnaire developed by an expert panel. Questionnaire asks about prior training and contact with potential victims of trafficking, perceived and actual human trafficking knowledge, confidence in responding to human trafficking, and interest in future human trafficking training. Results 13% participants reported previous contact with a patient they knew or suspected of having been trafficked; among maternity services professionals this was 20.4%. However, 86.8% (n=679) reported lacking knowledge of what questions to ask to identify potential victims and 78.3% (n=613) reported that they had insufficient training to assist trafficked people. 71% (n=556), 67.5% (n=528) and 53.4% (n=418) lacked confidence in making appropriate referrals for men, women and children, respectively, who had been trafficked. 95.3% (n=746) of respondents were unaware of the scale of human trafficking in the UK, and 76.5% (n=598) were unaware that calling the police could put patients in more danger. Psychometric analysis showed that subscales measuring perceived knowledge, actual knowledge and confidence to respond to human trafficking demonstrated good internal consistency (Cronbach's αs 0.93, 0.63 and 0.64, respectively) and internal correlations. Conclusions NHS professionals working in secondary care are in contact with potential

The topic of modern-day slavery or human trafficking has received increased media and national attention. However, to date there has been limited research on the nature and scope of human trafficking in the United States. This article describes and synthesizes nine reports that assess the U.S. service organizations' legal representative knowledge of, and experience with, human trafficking cases, as well as information from actual cases and media reports. This article has five main goals: (a) to define what human trafficking is, and is not; (b) to describe factors identified as contributing to vulnerability to being trafficked and keeping a person entrapped in the situation; (c) to examine how the crime of human trafficking differs from other kinds of crimes in the United States; (d) to explore how human trafficking victims are identified; and, (e) to provide recommendations to better address human trafficking in the United States.

Functional links between mucolipin-1 and Ca2+-dependent membrane trafficking in mucolipidosis IV

Most of the membrane trafficking phenomena including those involving the interactions between endosomes and lysosomes are regulated by changes in intracellular Ca 2+ (Ca i ). These processes are disturbed in some types of mucolipidoses and other lysosomal storage disorders, such as mucolipidosis IV (MLIV), a neurological disorder that usually presents during the first year of life with blindness, cognitive impairment, and psychomotor delays. It is caused by mutations in MCOLN1, the gene encoding mucolipin-1 (MLN1), which we have recently established to represent a Ca 2+ -permeable cation channel that is transiently modulated by changes in Ca i . The cells of MLIV patients contain enlarged lysosomes that are likely associated with abnormal sorting and trafficking of these and related organelles. We studied fibroblasts from MLIV patients and found disturbed Ca 2+ signaling and large acidic organelles such as late endosomes and lysosomes (LEL) with altered cellular localization in these cells. The fusion between LEL vesicles in these cells was defective. This is a Ca 2+ -dependent process related to signaling pathways involved in regulation of Ca 2+ homeostasis and trafficking. The MLN1 channels could play a key role in Ca 2+ release from LEL vesicles, which triggers the fusion and trafficking of these organelles. The characterization of this MLN1-mediated Ca 2+ -dependent process should provide new insights into the pathophysiological mechanisms that lead to the development of MLIV and other mucolipidoses associated with similar disturbances in membrane trafficking

PINK1 regulates mitochondrial trafficking in dendrites of cortical neurons through mitochondrial PKA.

Mitochondrial Protein Kinase A (PKA) and PTEN-induced kinase 1 (PINK1), which is linked to Parkinson's disease, are two neuroprotective serine/threonine kinases that regulate dendrite remodeling and mitochondrial function. We have previously shown that PINK1 regulates dendrite morphology by enhancing PKA activity. Here, we show the molecular mechanisms by which PINK1 and PKA in the mitochondrion interact to regulate dendrite remodeling, mitochondrial morphology, content, and trafficking in dendrites. PINK1-deficient cortical neurons exhibit impaired mitochondrial trafficking, reduced mitochondrial content, fragmented mitochondria, and a reduction in dendrite outgrowth compared to wild-type neurons. Transient expression of wild-type, but not a PKA-binding-deficient mutant of the PKA-mitochondrial scaffold dual-specificity A Kinase Anchoring Protein 1 (D-AKAP1), restores mitochondrial trafficking, morphology, and content in dendrites of PINK1-deficient cortical neurons suggesting that recruiting PKA to the mitochondrion reverses mitochondrial pathology in dendrites induced by loss of PINK1. Mechanistically, full-length and cleaved forms of PINK1 increase the binding of the regulatory subunit β of PKA (PKA/RIIβ) to D-AKAP1 to enhance the autocatalytic-mediated phosphorylation of PKA/RIIβ and PKA activity. D-AKAP1/PKA governs mitochondrial trafficking in dendrites via the Miro-2/TRAK2 complex and by increasing the phosphorylation of Miro-2. Our study identifies a new role of D-AKAP1 in regulating mitochondrial trafficking through Miro-2, and supports a model in which PINK1 and mitochondrial PKA participate in a similar neuroprotective signaling pathway to maintain dendrite connectivity. © 2017 International Society for Neurochemistry.

This paper investigates the impact of legalized prostitution on human trafficking inflows. According to economic theory, there are two opposing effects of unknown magnitude. The scale effect of legalized prostitution leads to an expansion of the prostitution market, increasing human trafficking, while the substitution effect reduces demand for trafficked women as legal prostitutes are favored over trafficked ones. Our empirical analysis for a cross-section of up to 150 countries shows that th...

Estradiol-induced estrogen receptor-alpha trafficking.

Science.gov (United States)

Bondar, Galyna; Kuo, John; Hamid, Naheed; Micevych, Paul

2009-12-02

Estradiol has rapid actions in the CNS that are mediated by membrane estrogen receptors (ERs) and activate cell signaling pathways through interaction with metabotropic glutamate receptors (mGluRs). Membrane-initiated estradiol signaling increases the free cytoplasmic calcium concentration ([Ca(2+)](i)) that stimulates the synthesis of neuroprogesterone in astrocytes. We used surface biotinylation to demonstrate that ERalpha has an extracellular portion. In addition to the full-length ERalpha [apparent molecular weight (MW), 66 kDa], surface biotinylation labeled an ERalpha-immunoreactive protein (MW, approximately 52 kDa) identified by both COOH- and NH(2)-directed antibodies. Estradiol treatment regulated membrane levels of both proteins in parallel: within 5 min, estradiol significantly increased membrane levels of the 66 and 52 kDa ERalpha. Internalization, a measure of membrane receptor activation, was also increased by estradiol with a similar time course. Continuous treatment with estradiol for 24-48 h reduced ERalpha levels, suggesting receptor downregulation. Estradiol also increased mGluR1a trafficking and internalization, consistent with the proposed ERalpha-mGluR1a interaction. Blocking ER with ICI 182,780 or mGluR1a with LY 367385 prevented ERalpha trafficking to and from the membrane. Estradiol-induced [Ca(2+)](i) flux was also significantly increased at the time of peak ERalpha activation/internalization. These results demonstrate that ERalpha is present in the membrane and has an extracellular portion. Furthermore, membrane levels and internalization of ERalpha are regulated by estradiol and mGluR1a ligands. The pattern of trafficking into and out of the membrane suggests that the changing concentration of estradiol during the estrous cycle regulates ERalpha to augment and then terminate membrane-initiated signaling.

Estradiol has rapid actions in the central nervous system, which are mediated by membrane estrogen receptors (ERs) and activate cell signaling pathways through interaction with metabotropic glutamate receptors (mGluRs). Membrane-initiated estradiol signaling increases the free cytoplasmic calcium concentration ([Ca2+]i) that stimulates the synthesis of neuroprogesterone in astrocytes. We used surface biotinylation to demonstrate that ERα has an extracellular portion. In addition to the full length ERα (apparent M.W. 66 kDa), surface biotinylation labeled an ERα-immunoreactive protein (M.W. ~ 52 kDa) identified by both COOH- and NH2-directed antibodies. Estradiol treatment regulated membrane levels of both proteins in parallel: within 5 min, estradiol significantly increased membrane levels of the 66 kDa and 52 kDa ERα. Internalization, a measure of membrane receptor activation, was also increased by estradiol with a similar time course. Continuous treatment with estradiol for 24–48 hr reduced ERα levels, suggesting receptor down-regulation. Estradiol also increased mGluR1a trafficking and internalization, consistent with the proposed ERα-mGluR1a interaction.

Stargazin regulates AMPA receptor trafficking through adaptor protein complexes during long-term depression

2013-11-01

Long-term depression (LTD) underlies learning and memory in various brain regions. Although postsynaptic AMPA receptor trafficking mediates LTD, its underlying molecular mechanisms remain largely unclear. Here we show that stargazin, a transmembrane AMPA receptor regulatory protein, forms a ternary complex with adaptor proteins AP-2 and AP-3A in hippocampal neurons, depending on its phosphorylation state. Inhibiting the stargazin-AP-2 interaction disrupts NMDA-induced AMPA receptor endocytosis, and inhibiting that of stargazin-AP-3A abrogates the late endosomal/lysosomal trafficking of AMPA receptors, thereby upregulating receptor recycling to the cell surface. Similarly, stargazin’s interaction with AP-2 or AP-3A is necessary for low-frequency stimulus-evoked LTD in CA1 hippocampal neurons. Thus, stargazin has a crucial role in NMDA-dependent LTD by regulating two trafficking pathways of AMPA receptors—transport from the cell surface to early endosomes and from early endosomes to late endosomes/lysosomes—through its sequential binding to AP-2 and AP-3A.

Live-cell imaging methods can provide critical real-time receptor trafficking measurements. Here, we describe an optical tool to study synaptic γ-aminobutyric acid (GABA) type A receptor (GABA A R) dynamics through adaptable fluorescent-tracking capabilities. A fluorogen-activating peptide (FAP) was genetically inserted into a GABA A R γ2 subunit tagged with pH-sensitive green fluorescent protein (γ2 pH FAP). The FAP selectively binds and activates Malachite Green (MG) dyes that are otherwise non-fluorescent in solution. γ2 pH FAP GABA A Rs are expressed at the cell surface in transfected cortical neurons, form synaptic clusters and do not perturb neuronal development. Electrophysiological studies show γ2 pH FAP GABA A Rs respond to GABA and exhibit positive modulation upon stimulation with the benzodiazepine diazepam. Imaging studies using γ2 pH FAP-transfected neurons and MG dyes show time-dependent receptor accumulation into intracellular vesicles, revealing constitutive endosomal and lysosomal trafficking. Simultaneous analysis of synaptic, surface and lysosomal receptors using the γ2 pH FAP-MG dye approach reveals enhanced GABA A R turnover following a bicucculine-induced seizure paradigm, a finding not detected by standard surface receptor measurements. To our knowledge, this is the first application of the FAP-MG dye system in neurons, demonstrating the versatility to study nearly all phases of GABA A R trafficking. © 2017.

Semantic dementia without surface dyslexia in Spanish: unimpaired reading with impaired semantics.

Science.gov (United States)

Wilson, Maximiliano A; Martínez-Cuitiño, Macarena

2012-01-01

Surface dyslexia has been attributed to an overreliance on the sub-lexical route for reading. Typically, surface dyslexic patients commit regularisation errors when reading irregular words. Also, semantic dementia has often been associated with surface dyslexia, leading to some explanations of the reading impairment that stress the role of semantics in irregular word reading. Nevertheless, some patients have been reported with unimpaired ability to read irregular words, even though they show severe comprehension impairment. We present the case of M.B., the first Spanish-speaking semantic dementia patient to be reported who shows unimpaired reading of non-words, regular words, and - most strikingly - irregular loan words. M.B. has severely impaired comprehension of the same words he reads correctly (whether regular or irregular). We argue that M.B.'s pattern of performance shows that irregular words can be correctly read even with impaired semantic knowledge corresponding to those words.

Face-to-face mandatory child protection and/or vulnerable adults training sessions at 10 secondary healthcare provider organisations in England, and meetings of the UK College of Emergency Medicine. 782/892 (84.4%) NHS professionals participated, including from emergency medicine, maternity, mental health, paediatrics and other clinical disciplines. Self-completed questionnaire developed by an expert panel. Questionnaire asks about prior training and contact with potential victims of trafficking, perceived and actual human trafficking knowledge, confidence in responding to human trafficking, and interest in future human trafficking training. 13% participants reported previous contact with a patient they knew or suspected of having been trafficked; among maternity services professionals this was 20.4%. However, 86.8% (n=679) reported lacking knowledge of what questions to ask to identify potential victims and 78.3% (n=613) reported that they had insufficient training to assist trafficked people. 71% (n=556), 67.5% (n=528) and 53.4% (n=418) lacked confidence in making appropriate referrals for men, women and children, respectively, who had been trafficked. 95.3% (n=746) of respondents were unaware of the scale of human trafficking in the UK, and 76.5% (n=598) were unaware that calling the police could put patients in more danger. Psychometric analysis showed that subscales measuring perceived knowledge, actual knowledge and confidence to respond to human trafficking demonstrated good internal consistency (Cronbach's αs 0.93, 0.63 and 0.64, respectively) and internal correlations. NHS professionals working in secondary care are in contact with potential victims of human trafficking, but lack knowledge and confidence in

Human trafficking and the dental professional.

O'Callaghan, Michael G

2012-05-01

"Human trafficking" is a term for a modern form of slavery. It is a criminal human rights violation and a significant health issue. Dental professionals can assist in recognizing victims of trafficking. The author conducted a PubMed search of the English-language literature through May 2011, which yielded no articles meeting the search criteria "dentistry" and "human trafficking prostitution." Given these results, the author reviewed articles published in medical journals, reports from both governmental and nongovernmental agencies and lay literature. The author examines the present state of human trafficking and provides information--including specific questions to ask--to help dentists identify victims. In addition, the author suggests means of notifying authorities and assisting trafficking victims. He also examines the health care needs of these patients. Human trafficking is a global problem, with thousands of victims in the United States, including many women and children. Dentists have a responsibility to act for the benefit of others, which includes detecting signs of abuse and neglect. Dental professionals are on the front lines with respect to encountering and identifying potential victims who seek dental treatment. Dentists can combat human trafficking by becoming informed and by maintaining vigilance in their practices.

The Palermo Protocol: Trafficking Takes it All

Directory of Open Access Journals (Sweden)

Jónína Einarsdóttir

2014-12-01

Full Text Available The Palermo Protocol is the outcome of bargain and lobbying with global institutions, NGOs and government representatives embattling to enforce their interests. The outcome is the concept of trafficking that embraces the struggles against prostitution, slavery and child labour. This broad concept has allowed various local cultural practices and survival strategies of those who live under difficult conditions to become classified as trafficking. While such definition may facilitate fundraising there are adverse consequences to be considered. Firstly, hazardous conditions of children that obviously are not trafficking tend to become ignored. Second, the victims of “real” trafficking become invisible by the excessive number of children allegedly trafficked. Third, the broad definition of trafficking has contributed to criminalization of whole communities and consequent conflicts between NGOs engaged in anti-trafficking activities and the communities involved. Such a situation is not in the best interest of the children involved. Rather than spending huge amount of resources on the conventional anti-trafficking measures there is a need to address the root causes of whatsoever unacceptable condition a child is suffering from.

Polarized axonal surface expression of neuronal KCNQ potassium channels is regulated by calmodulin interaction with KCNQ2 subunit.

Directory of Open Access Journals (Sweden)

John P Cavaretta

Full Text Available KCNQ potassium channels composed of KCNQ2 and KCNQ3 subunits give rise to the M-current, a slow-activating and non-inactivating voltage-dependent potassium current that limits repetitive firing of action potentials. KCNQ channels are enriched at the surface of axons and axonal initial segments, the sites for action potential generation and modulation. Their enrichment at the axonal surface is impaired by mutations in KCNQ2 carboxy-terminal tail that cause benign familial neonatal convulsion and myokymia, suggesting that their correct surface distribution and density at the axon is crucial for control of neuronal excitability. However, the molecular mechanisms responsible for regulating enrichment of KCNQ channels at the neuronal axon remain elusive. Here, we show that enrichment of KCNQ channels at the axonal surface of dissociated rat hippocampal cultured neurons is regulated by ubiquitous calcium sensor calmodulin. Using immunocytochemistry and the cluster of differentiation 4 (CD4 membrane protein as a trafficking reporter, we demonstrate that fusion of KCNQ2 carboxy-terminal tail is sufficient to target CD4 protein to the axonal surface whereas inhibition of calmodulin binding to KCNQ2 abolishes axonal surface expression of CD4 fusion proteins by retaining them in the endoplasmic reticulum. Disruption of calmodulin binding to KCNQ2 also impairs enrichment of heteromeric KCNQ2/KCNQ3 channels at the axonal surface by blocking their trafficking from the endoplasmic reticulum to the axon. Consistently, hippocampal neuronal excitability is dampened by transient expression of wild-type KCNQ2 but not mutant KCNQ2 deficient in calmodulin binding. Furthermore, coexpression of mutant calmodulin, which can interact with KCNQ2/KCNQ3 channels but not calcium, reduces but does not abolish their enrichment at the axonal surface, suggesting that apo calmodulin but not calcium-bound calmodulin is necessary for their preferential targeting to the axonal

2006-03-01

Full Text Available Abstract Background The identification of protein trafficking signals, and their interacting mechanisms, is a fundamental objective of modern biology. Unfortunately, the analysis of trafficking signals is complicated by their topography, hierarchical nature and regulation. Powerful strategies to test candidate motifs include their ability to direct simpler reporter proteins, to which they are fused, to the appropriate cellular compartment. However, present reporters are limited by their endogenous expression, paucity of cloning sites, and difficult detection in live cells. Results Consequently, we have engineered a mammalian expression vector encoding a novel trafficking reporter – pIN-G – consisting of a simple, type I integral protein bearing permissive intra/extracellular cloning sites, green fluorescent protein (GFP, cMyc and HA epitope tags. Fluorescence imaging, flow cytometry and biochemical assays of transfected HEK293 cells, confirm the size, topology and surface expression of PIN-G. Moreover, a pIN-G fusion construct, containing a Trans-Golgi Network (TGN targeting determinant, internalises rapidly from the cell surface and localises to the TGN. Additionally, another PIN-G fusion protein and its mutants reveal trafficking determinants in the cytoplasmic carboxy terminus of Kv1.4 voltage-gated potassium channels. Conclusion Together, these data indicate that pIN-G is a versatile, powerful, new reporter for analysing signals controlling membrane protein trafficking, surface expression and dynamics.

Subcellular trafficking of FGF controls tracheal invasion of Drosophila flight muscle.

Peterson, Soren J; Krasnow, Mark A

2015-01-15

To meet the extreme oxygen demand of insect flight muscle, tracheal (respiratory) tubes ramify not only on its surface, as in other tissues, but also within T-tubules and ultimately surrounding every mitochondrion. Although this remarkable physiological specialization has long been recognized, its cellular and molecular basis is unknown. Here, we show that Drosophila tracheoles invade flight muscle T-tubules through transient surface openings. Like other tracheal branching events, invasion requires the Branchless FGF pathway. However, localization of the FGF chemoattractant changes from all muscle membranes to T-tubules as invasion begins. Core regulators of epithelial basolateral membrane identity localize to T-tubules, and knockdown of AP-1γ, required for basolateral trafficking, redirects FGF from T-tubules to surface, increasing tracheal surface ramification and preventing invasion. We propose that tracheal invasion is controlled by an AP-1-dependent switch in FGF trafficking. Thus, subcellular targeting of a chemoattractant can direct outgrowth to specific domains, including inside the cell. Copyright © 2015 Elsevier Inc. All rights reserved.

Human Trafficking: How Nurses Can Make a Difference.

Science.gov (United States)

Scannell, Meredith; MacDonald, Andrea E; Berger, Amanda; Boyer, Nichole

Human trafficking is a human rights violation and a global health problem. Victims of human trafficking have medical and mental health sequelae requiring specific healthcare interventions. Healthcare professionals may be the initial contact that these victims make outside the world of trafficking. Healthcare professionals are key agents in the identification of human trafficking, which is essential in eliminating this public health problem. Unfortunately, healthcare professionals are not always able to detect signs of human trafficking. Failure to detect results in missed opportunities to assist victims. This is a case report of a victim of human trafficking who presented to an emergency department with medical and mental health issues. Despite numerous encounters with different healthcare professionals, signs and symptoms of human trafficking were not identified. Skilled assessment made by a forensic nurse alerted the healthcare team to clear features of human trafficking associated with this person. Through this case report we illustrate the key role the nurse played in identifying signs of human trafficking. Improvement of human trafficking educational programs is highlighted as a key adjunct to improving detection and facilitating the proper treatment of victims.

Role of Occupational Therapy in Combating Human Trafficking.

Science.gov (United States)

Gorman, Kathleen W; Hatkevich, Beth Ann

Human trafficking is a modern-day form of slavery that includes sex trafficking, labor trafficking, and trafficking of children. It is estimated that 35.8 million people are enslaved around the world. Because of the traumatic experiences that victims of human trafficking encounter, the needs of victims are extensive and require the services of several providers, including health care providers, for victims to transform into survivors and thrivers. Currently, the role of occupational therapy is minimal and unexplored. The profession of occupational therapy has the capacity of having a profound role in both providing client-centered care services to victims and survivors of human trafficking and partaking in preventive advocacy efforts to combat human trafficking. Further advocacy efforts are required to promote the profession of occupational therapy in combating human trafficking. Copyright © 2016 by the American Occupational Therapy Association, Inc.

Biopolitical management, economic calculation and "trafficked women".

Science.gov (United States)

Berman, Jacqueline

2010-01-01

Narratives surrounding human trafficking, especially trafficking in women for sex work, employ gendered and racialized tropes that have among their effects, a shrouding of women's economic decision-making and state collusion in benefiting from their labour. This paper explores the operation of these narratives in order to understand the ways in which they mask the economics of trafficking by sensationalizing the sexual and criminal aspects of it, which in turn allows the state to pursue political projects under the guise of a benevolent concern for trafficked women and/or protection of its own citizens. This paper will explore one national example: Article 18 of Italian Law 40 (1998). I argue that its passage has led to an increase in cooperation with criminal prosecution of traffickers largely because it approaches trafficked women as capable of making decisions about how and what they themselves want to do. This paper will also consider a more global approach to trafficking embedded in the concept of "migration management", an International Organization for Migration (IOM) framework that is now shaping EU, US and other national immigration laws and policies that impact trafficking. It will also examine the inherent limitations of both the national and global approach as an occasion to unpack how Article 18 and Migration Management function as forms of biopolitical management that participate in the production of "trafficking victims" into a massified population to be managed, rather than engender a more engaged discussion of what constitutes trafficking and how to redress it.

Pakistan is both a country of origin and destination as far as women trafficking is concerned. Poverty, gender discrimination, lack of education, and ignorance about legal rights are some of the underlying causes. Available data suggest several areas of concern, like, for instance: direct health effects, maladaptive coping leading to the use of illicit drugs, and inaccessibility to healthcare facilities. Therefore, numerous interventions would be required at three levels: the prevention of trafficking, the protection of victims and the prosecution of the traffickers.

Research highlights: → ARF1 activation is involved in the EGFR transport to the ER and the nucleus. → Assembly of γ-COP coatomer mediates EGFR transport to the ER and the nucleus. → Golgi-to-ER retrograde trafficking regulates nuclear transport of EGFR. -- Abstract: Emerging evidence indicates that cell surface receptors, such as the entire epidermal growth factor receptor (EGFR) family, have been shown to localize in the nucleus. A retrograde route from the Golgi to the endoplasmic reticulum (ER) is postulated to be involved in the EGFR trafficking to the nucleus; however, the molecular mechanism in this proposed model remains unexplored. Here, we demonstrate that membrane-embedded vesicular trafficking is involved in the nuclear transport of EGFR. Confocal immunofluorescence reveals that in response to EGF, a portion of EGFR redistributes to the Golgi and the ER, where its NH 2 -terminus resides within the lumen of Golgi/ER and COOH-terminus is exposed to the cytoplasm. Blockage of the Golgi-to-ER retrograde trafficking by brefeldin A or dominant mutants of the small GTPase ADP-ribosylation factor, which both resulted in the disassembly of the coat protein complex I (COPI) coat to the Golgi, inhibit EGFR transport to the ER and the nucleus. We further find that EGF-dependent nuclear transport of EGFR is regulated by retrograde trafficking from the Golgi to the ER involving an association of EGFR with γ-COP, one of the subunits of the COPI coatomer. Our findings experimentally provide a comprehensive pathway that nuclear transport of EGFR is regulated by COPI-mediated vesicular trafficking from the Golgi to the ER, and may serve as a general mechanism in regulating the nuclear transport of other cell surface receptors.

Intracellular trafficking pathways of Cx43 gap junction channels.

Science.gov (United States)

Epifantseva, Irina; Shaw, Robin M

2018-01-01

Gap Junction (GJ) channels, including the most common Connexin 43 (Cx43), have fundamental roles in excitable tissues by facilitating rapid transmission of action potentials between adjacent cells. For instance, synchronization during each heartbeat is regulated by these ion channels at the cardiomyocyte cell-cell border. Cx43 protein has a short half-life, and rapid synthesis and timely delivery of those proteins to particular subdomains are crucial for the cellular organization of gap junctions and maintenance of intracellular coupling. Impairment in gap junction trafficking contributes to dangerous complications in diseased hearts such as the arrhythmias of sudden cardiac death. Of recent interest are the protein-protein interactions with the Cx43 carboxy-terminus. These interactions have significant impact on the full length Cx43 lifecycle and also contribute to trafficking of Cx43 as well as possibly other functions. We are learning that many of the known non-canonical roles of Cx43 can be attributed to the recently identified six endogenous Cx43 truncated isoforms which are produced by internal translation. In general, alternative translation is a new leading edge for proteome expansion and therapeutic drug development. This review highlights recent mechanisms identified in the trafficking of gap junction channels, involvement of other proteins contributing to the delivery of channels to the cell-cell border, and understanding of possible roles of the newly discovered alternatively translated isoforms in Cx43 biology.

Child organ trafficking: global reality and inadequate international response.

Science.gov (United States)

Bagheri, Alireza

2016-06-01

In organ transplantation, the demand for human organs has grown far faster than the supply of organs. This has opened the door for illegal organ trade and trafficking including from children. Organized crime groups and individual organ brokers exploit the situation and, as a result, black markets are becoming more numerous and organized organ trafficking is expanding worldwide. While underprivileged and vulnerable men and women in developing countries are a major source of trafficked organs, and may themselves be trafficked for the purpose of illegal organ removal and trade, children are at especial risk of exploitation. With the confirmed cases of children being trafficked for their organs, child organ trafficking, which once called a "modern urban legend", is a sad reality in today's world. By presenting a global picture of child organ trafficking, this paper emphasizes that child organ trafficking is no longer a myth but a reality which has to be addressed. It argues that the international efforts against organ trafficking and trafficking in human beings for organ removal have failed to address child organ trafficking adequately. This chapter suggests that more orchestrated international collaboration as well as development of preventive measure and legally binding documents are needed to fight child organ trafficking and to support its victims.

Was Trafficking in Persons Really Criminalised?

Directory of Open Access Journals (Sweden)

Kristiina Kangaspunta

2015-04-01

Full Text Available This paper examines the successes and setbacks in the criminal justice response to trafficking in persons. While today, the majority of countries have passed specific legislation criminalising human trafficking in response to the United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, there are still very few convictions of trafficking. Using currently available knowledge, this paper discusses four possible reasons for low conviction rates. Further, the paper suggests that due to the heavy dependency on victim testimonies when prosecuting trafficking in persons crimes, members of criminal organisations that are easily identifiable by victims may face criminal charges more frequently than other members of the criminal group, particularly those in positions of greater responsibility who profit the most from the criminal activities. In this context, the exceptionally high number of women among convicted offenders is explored.

Impaired perception of surface tilt in progressive supranuclear palsy.

Marian L Dale

Full Text Available Progressive supranuclear palsy (PSP is characterized by early postural instability and backward falls. The mechanisms underlying backward postural instability in PSP are not understood. The aim of this study was to test the hypothesis that postural instability in PSP is a result of dysfunction in the perception of postural verticality.We gathered posturography data on 12 subjects with PSP to compare with 12 subjects with idiopathic Parkinson's Disease (PD and 12 healthy subjects. Objective tests of postural impairment included: dynamic sensory perception tests of gravity and of surface oscillations, postural responses to surface perturbations, the sensory organization test of postural sway under altered sensory conditions and limits of stability in stance.Perception of toes up (but not toes down surface tilt was reduced in subjects with PSP compared to both control subjects (p≤0.001 standing, p≤0.007 seated and subjects with PD (p≤0.03 standing, p≤0.04 seated. Subjects with PSP, PD and normal controls accurately perceived the direction of gravity when standing on a tilting surface. Unlike PD and control subjects, subjects with PSP exerted less postural corrective torque in response to toes up surface tilts.Difficulty perceiving backward tilt of the surface or body may account for backward falls and postural impairments in patients with PSP. These observations suggest that abnormal central integration of sensory inputs for perception of body and surface orientation contributes to the pathophysiology of postural instability in PSP.

Human trafficking is a pressing social justice concern. Social work is uniquely situated to address this problem. However, despite the profession's commitment to social justice, the scholarship to equip social workers to address this issue has been largely absent from professional discourse. To address this gap, this article helps social work practitioners to assist victims of human trafficking. After orienting readers to the scope and process of human trafficking, the topics of victim identification, exit from trafficking, and the restoration of psychological wellness are discussed. By equipping themselves in these three areas, practitioners can advance social justice on behalf of some of the most exploited people in the world.

Trafficking in Persons for Ransom and the Need to Expand the Interpretation of Article 3 of the UN Trafficking Protocol

Directory of Open Access Journals (Sweden)

Mogos O Brhane

2015-04-01

Full Text Available As the nature of trafficking in persons continues to manifest itself in myriad ways all over the world, interpretation of the UN Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children (Trafficking Protocol, should be broadened to include newly emerging practices that are similar in nature to those it has already embraced under its definition. The Protocol appears to encompass other forms of trafficking which are unnamed or unforeseen by the definition provided under Article 3. It is time to expand its spectrum. Northeast Africa is plagued by a unique form of trafficking in persons—trafficking in persons for ransom. This involves a practice where people are smuggled, abducted, kidnapped and tortured to compel their relatives and families to pay ransom money. Victims are nationals of Eritrea, Ethiopia, Sudan and South Sudan. However, as Northeast Africa hosts particularly high numbers of Eritrean migrants and the largest Eritrean diaspora globally, Eritreans are very vulnerable to being targeted for trafficking for ransom. As trafficking for ransom is an emerging trend, legal ramifications have never been studied in full. Few reports try to address legal issues around the phenomenon, and those that do only give it a few paragraphs of attention. There is need for a closer look at this form of trafficking.

A brain-enriched multi-domain scaffolding protein, neurobeachin has been identified as a candidate gene for autism patients. Mutations in the synaptic adhesion protein cell adhesion molecule 1 (CADM1) are also associated with autism spectrum disorder, a neurodevelopmental disorder of uncertain molecular origin. Potential roles of neurobeachin and CADM1 have been suggested to a function of vesicle transport in endosomal trafficking. It seems that protein kinase B (AKT) and cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA) have key roles in the neuron membrane trafficking involved in the pathogenesis of autism. Attention deficit hyperactivity disorder (ADHD) is documented to dopaminergic insufficiencies, which is attributed to synaptic dysfunction of dopamine transporter (DAT). AKT is also essential for the DAT cell-surface redistribution. In the present paper, we summarize and discuss the importance of several protein kinases that regulate the membrane trafficking involved in autism and ADHD, suggesting new targets for therapeutic intervention.

Salmonella Disrupts Host Endocytic Trafficking by SopD2-Mediated Inhibition of Rab7

Directory of Open Access Journals (Sweden)

Vanessa M. D’Costa

2015-09-01

Full Text Available Intracellular bacterial pathogens of a diverse nature share the ability to evade host immunity by impairing trafficking of endocytic cargo to lysosomes for degradation, a process that is poorly understood. Here, we show that the Salmonella enterica type 3 secreted effector SopD2 mediates this process by binding the host regulatory GTPase Rab7 and inhibiting its nucleotide exchange. Consequently, this limits Rab7 interaction with its dynein- and kinesin-binding effectors RILP and FYCO1 and thereby disrupts host-driven regulation of microtubule motors. Our study identifies a bacterial effector capable of directly binding and thereby modulating Rab7 activity and a mechanism of endocytic trafficking disruption that may provide insight into the pathogenesis of other bacteria. Additionally, we provide a powerful tool for the study of Rab7 function, and a potential therapeutic target.

Full Text Available The Supreme Court of India, In Baby Manji Yamada versus Union of India & Anr. [2008] INSC 1656, popularly known as Manji Case, declared that Commercial Surrogacy is legal in India. As we know that, India is a developing country and here, most of the peoples are very poor and illiterate. Recently, human trafficking was increase with an uncontrollable rate in the entire world. In addition, making Commercialization of Surrogacy legal had already give birth to a new form of trafficking. Where, illiterate women from poor section is trafficked to run the reproductive industry of the Surrogacy. As we know that the traffickers, they used to trafficked girls/women for prostitution but now after the legalization of Commercial Surrogacy, they will trafficked girl/women for the reproductive industry as a raw material. The Immoral Trafficking Prevention Act (ITPA, 1956 and Sections 366(A and 372 of the Indian Penal Code, 1860 are the existing laws of India, which deals with human trafficking. However, none of these provisions contains any solution, to deal with this new serious issue of trafficking of women/girls for the purpose of Commercial Surrogacy in reproductive industries. These existing laws as well as the pending draft bill of Assisted Reproductive Technologies (ART Regulation Bill, 2010 needs an amendment to check this crime against women once again to protect the rights and health of the women.

Human trafficking law and social structures.

Wooditch, Alese

2012-08-01

Human trafficking has only recently emerged at the forefront of policy reform, even in developed nations. Yet, heightened awareness of the issue has not translated into effective policy as the majority of nations have ineffective antitrafficking practices; many countries have failed to criminalize human trafficking, whereas others do not actively enforce statutes in place. By applying Black's theory of law, this study offers a preliminary understanding into the variation of global prosecutorial efforts in human trafficking and adequacy of antitrafficking law. To isolate this relationship, the effects of trafficking markets are controlled. As with prior research, the study finds limited support for the theory. The article concludes with a discussion on the implications of the quantity of antitrafficking law and morphology association for policy development.

Ubiquilin 1 (UBQLN1) is a ubiquitin-like protein, which has been shown to play a central role in regulating the proteasomal degradation of various proteins, including the presenilins. We recently reported that DNA variants in UBQLN1 increase the risk for Alzheimer disease, by influencing expression of this gene in brain. Here we present the first assessment of the effects of UBQLN1 on the metabolism of the amyloid precursor protein (APP). For this purpose, we employed RNA interference to down-regulate UBQLN1 in a variety of neuronal and non-neuronal cell lines. We demonstrate that down-regulation of UBQLN1 accelerates the maturation and intracellular trafficking of APP, while not interfering with alpha-, beta-, or gamma-secretase levels or activity. UBQLN1 knockdown increased the ratio of APP mature/immature, increased levels of full-length APP on the cell surface, and enhanced the secretion of sAPP (alpha- and beta-forms). Moreover, UBQLN1 knockdown increased levels of secreted Abeta40 and Abeta42. Finally, employing a fluorescence resonance energy transfer-based assay, we show that UBQLN1 and APP come into close proximity in intact cells, independently of the presence of the presenilins. Collectively, our findings suggest that UBQLN1 may normally serve as a cytoplasmic "gatekeeper" that may control APP trafficking from intracellular compartments to the cell surface. These findings suggest that changes in UBQLN1 steady-state levels affect APP trafficking and processing, thereby influencing the generation of Abeta.

A trafficking in human being is not a frequent criminal offence but with its consequences belongs to the most dangerous crimes. After the Velvet revolution the relevance of this crime has raised subsequently and therefore the regulation of this crime requires particular attention. It is important to find new ways and improve curren...

Female sex trafficking is a pressing concern. In this article, we provide a comprehensive overview of relevant issues regarding the concept of female sex trafficking and research in the field of human trafficking, drawing on a variety of disciplines, including economics, gender and sexuality studies, psychology, sociology, law, and social work. We discuss the debates surrounding the definition of human trafficking, compare and contrast it with human smuggling, and outline connections between female sex trafficking and the issue of sex work and prostitution. We further discuss the history and current estimations of female sex trafficking. We then outline the main actors in female sex trafficking, including trafficked persons, traffickers, clients, and service providers, and we overview the trafficking process from recruitment to identification, recovery, and (re)integration. Finally, we conclude with recommendations for future research that tie together the concepts of vulnerability, exploitation, and long-term recovery and (re)integration.

Full Text Available Trafficking in human organs is a specific and complex criminal phenomenon that takes place in several phases, with the participation of a large number of actors, often covering several jurisdictions. To effectively countering are necessary conceptual and terminological demarcation of organ trafficking from other similar phenomena, fundamental scientifically research of its shape and dynamics, and the construction of an adequate legislative framework, both at the national and international level. This paper first analyses the conceptual - terminological framework in which research of organ trafficking is range, and then presents a review and analysis of the development of ethical and normative international standards aimed at prevention and suppression this phenomenon. In the end, we analysed the current solutions in the domestic legislation. Nowadays, there are two parallel legislative regime that regulate the matter of organ trafficking. The first legislative regime that organ trafficking treated exclusively as a modality of transnational crime of human trafficking, and a second, recent, that organ trafficking treats as forbidden (incriminating activity that violates a regulatory system of organ (tissue cells transplantation.

The objective of this study is to propose improvements of different means and methods for the prevention of illicit trafficking and the proliferation of nuclear weapons. An essential requirement imposed on authorities and operators through basic nuclear legislation is the establishment and implementation of: a) nuclear material accountancy and control; b) physical protection of nuclear material and facilities; and c) export/import control of nuclear material and, so called, dual-use items. The legislation would make it possible for the State nuclear authority to be informed continuously about the location and quantity of nuclear material in the country, and to monitor that it is under satisfactory protection and guard in accordance with the requirements. The introduction of requirements on licensing of practices and activities involving dual-use items, and other products used for nuclear weapons manufacturing, would also give the authority the possibility to prevent unauthorised transfers of such products. The nuclear legislation must clearly stipulate the distribution of responsibilities between nuclear authority, operator and employees. This would give a solid basis for attaining high safety culture, including positive motivation and active commitment among executives and other employees. It would also ensure that nuclear material would not be lost through negligence or internal criminal activities. A further step of improvements on the national level, would be the urgent and firm introduction of modern Quality Assurance and Internal Control Systems into all forms of nuclear activities. In modern, safety related quality control systems, the operator alone is responsible for all activities and operations, and he must establish an internal control that will ensure that the authority's rules and requirements are thoroughly implemented and adhered to. The operator's organisation, including competence and procedures, must be approved by the State authority. By means

2017-01-01

Human trafficking is commonly known as a criminal practice that takes place in the framework of sex trade: women and children are trafficked within a state, or from one state to another, for the purpose of sexual exploitation. Similarly, the early 20th century international conventions aimed to tackle ‘white slave traffic’, trafficking of women and children for sexual exploitation. However, it is misleading to see trafficking only within this context. People are trafficked so that they can be...

Vascular endothelial growth factor A (VEGF-A) regulates many aspects of vascular function. VEGF-A binding to vascular endothelial growth factor receptor 2 (VEGFR2) stimulates endothelial signal transduction and regulates multiple cellular responses. Activated VEGFR2 undergoes ubiquitination but the enzymes that regulate this post-translational modification are unclear. In this study, the de-ubiquitinating enzyme, USP8, is shown to regulate VEGFR2 trafficking, de-ubiquitination, proteolysis and signal transduction. USP8-depleted endothelial cells displayed altered VEGFR2 ubiquitination and production of a unique VEGFR2 extracellular domain proteolytic fragment caused by VEGFR2 accumulation in the endosome-lysosome system. In addition, perturbed VEGFR2 trafficking impaired VEGF-A-stimulated signal transduction in USP8-depleted cells. Thus, regulation of VEGFR2 ubiquitination and de-ubiquitination has important consequences for the endothelial cell response and vascular physiology. © 2015 The Authors.

RNA trafficking in parasitic plant systems

LeBlanc, Megan; Kim, Gunjune; Westwood, James H.

2012-01-01

RNA trafficking in plants contributes to local and long-distance coordination of plant development and response to the environment. However, investigations of mobile RNA identity and function are hindered by the inherent difficulty of tracing a given molecule of RNA from its cell of origin to its destination. Several methods have been used to address this problem, but all are limited to some extent by constraints associated with accurately sampling phloem sap or detecting trafficked RNA. Certain parasitic plant species form symplastic connections to their hosts and thereby provide an additional system for studying RNA trafficking. The haustorial connections of Cuscuta and Phelipanche species are similar to graft junctions in that they are able to transmit mRNAs, viral RNAs, siRNAs, and proteins from the host plants to the parasite. In contrast to other graft systems, these parasites form connections with host species that span a wide phylogenetic range, such that a high degree of nucleotide sequence divergence may exist between host and parasites and allow confident identification of most host RNAs in the parasite system. The ability to identify host RNAs in parasites, and vice versa, will facilitate genomics approaches to understanding RNA trafficking. This review discusses the nature of host–parasite connections and the potential significance of host RNAs for the parasite. Additional research on host–parasite interactions is needed to interpret results of RNA trafficking studies, but parasitic plants may provide a fascinating new perspective on RNA trafficking.

This article reviews an emergency department-based clinical vignette of a trafficked patient with co-occurring pregnancy-related, mental health, and substance use disorder issues. The authors, including a survivor of human trafficking, draw on their backgrounds in addiction care, human trafficking, emergency medicine, and psychiatry to review the literature on relevant general health and mental health consequences of trafficking and propose an approach to the clinical complexities this case presents. In their discussion, the authors explicate the deleterious role of implicit bias and diagnostic overshadowing in trafficked patients with co-occurring addiction and mental illness. Finally, the authors propose a trauma-informed, multidisciplinary response to potentially trafficked patients. © 2017 American Medical Association. All Rights Reserved.

Barcoding of GPCR trafficking and signaling through the various trafficking roadmaps by compartmentalized signaling networks.

Science.gov (United States)

Bahouth, Suleiman W; Nooh, Mohammed M

2017-08-01

Proper signaling by G protein coupled receptors (GPCR) is dependent on the specific repertoire of transducing, enzymatic and regulatory kinases and phosphatases that shape its signaling output. Activation and signaling of the GPCR through its cognate G protein is impacted by G protein-coupled receptor kinase (GRK)-imprinted "barcodes" that recruit β-arrestins to regulate subsequent desensitization, biased signaling and endocytosis of the GPCR. The outcome of agonist-internalized GPCR in endosomes is also regulated by sequence motifs or "barcodes" within the GPCR that mediate its recycling to the plasma membrane or retention and eventual degradation as well as its subsequent signaling in endosomes. Given the vast number of diverse sequences in GPCR, several trafficking mechanisms for endosomal GPCR have been described. The majority of recycling GPCR, are sorted out of endosomes in a "sequence-dependent pathway" anchored around a type-1 PDZ-binding module found in their C-tails. For a subset of these GPCR, a second "barcode" imprinted onto specific GPCR serine/threonine residues by compartmentalized kinase networks was required for their efficient recycling through the "sequence-dependent pathway". Mutating the serine/threonine residues involved, produced dramatic effects on GPCR trafficking, indicating that they played a major role in setting the trafficking itinerary of these GPCR. While endosomal SNX27, retromer/WASH complexes and actin were required for efficient sorting and budding of all these GPCR, additional proteins were required for GPCR sorting via the second "barcode". Here we will review recent developments in GPCR trafficking in general and the human β 1 -adrenergic receptor in particular across the various trafficking roadmaps. In addition, we will discuss the role of GPCR trafficking in regulating endosomal GPCR signaling, which promote biochemical and physiological effects that are distinct from those generated by the GPCR signal transduction

Getting out of the game: desistance from drug trafficking.

Science.gov (United States)

Campbell, Howard; Hansen, Tobin

2012-11-01

This ethnographic study was conducted along the U.S.-Mexico border, the centre of the western hemispheric illicit drugs trade. It examines factors that encouraged or discouraged drug traffickers to "get out of the game" (a common slang reference to leaving the drug business). In-depth, life history interviews were conducted of thirty ex-traffickers in the El Paso/Ciudad Juárez area. Participants discussed their experiences exiting drug trafficking and their retrospective, often conflicted, feelings about the trade. Although leaving drug trafficking is a complex and multi-faceted process, the principle factors for study participants were (1) punishment (by authorities or other traffickers), (2) self-image and identity, (3) social ties, (4) life course changes and (5) drug use/abuse. Traffickers often want to quit, but their divided self-identities make it difficult to relinquish the power and exhilaration they derive from the illicit drugs business. Harm reduction policies are needed that address the embeddedness of trafficker identities in dense webs of family, community, street gangs and transnational cartels, and the larger society, as well as the seductive appeal of Hollywood and pro-cartel narco-media. Traffickers need pathways that allow them to exit the illicit drugs business without surrendering their identity. Prison sentences are not enough to encourage traffickers to stop-also needed are culturally sensitive policies that help traffickers get out of the game and stay out. Copyright © 2012 Elsevier B.V.

A Novel High Content Imaging-Based Screen Identifies the Anti-Helminthic Niclosamide as an Inhibitor of Lysosome Anterograde Trafficking and Prostate Cancer Cell Invasion.

Directory of Open Access Journals (Sweden)

Magdalena L Circu

Full Text Available Lysosome trafficking plays a significant role in tumor invasion, a key event for the development of metastasis. Previous studies from our laboratory have demonstrated that the anterograde (outward movement of lysosomes to the cell surface in response to certain tumor microenvironment stimulus, such as hepatocyte growth factor (HGF or acidic extracellular pH (pHe, increases cathepsin B secretion and tumor cell invasion. Anterograde lysosome trafficking depends on sodium-proton exchanger activity and can be reversed by blocking these ion pumps with Troglitazone or EIPA. Since these drugs cannot be advanced into the clinic due to toxicity, we have designed a high-content assay to discover drugs that block peripheral lysosome trafficking with the goal of identifying novel drugs that inhibit tumor cell invasion. An automated high-content imaging system (Cellomics was used to measure the position of lysosomes relative to the nucleus. Among a total of 2210 repurposed and natural product drugs screened, 18 "hits" were identified. One of the compounds identified as an anterograde lysosome trafficking inhibitor was niclosamide, a marketed human anti-helminthic drug. Further studies revealed that niclosamide blocked acidic pHe, HGF, and epidermal growth factor (EGF-induced anterograde lysosome redistribution, protease secretion, motility, and invasion of DU145 castrate resistant prostate cancer cells at clinically relevant concentrations. In an effort to identify the mechanism by which niclosamide prevented anterograde lysosome movement, we found that this drug exhibited no significant effect on the level of ATP, microtubules or actin filaments, and had minimal effect on the PI3K and MAPK pathways. Niclosamide collapsed intralysosomal pH without disruption of the lysosome membrane, while bafilomycin, an agent that impairs lysosome acidification, was also found to induce JLA in our model. Taken together, these data suggest that niclosamide promotes

National Human Trafficking Initiatives: Dimensions of Policy Diffusion.

Yoo, Eun-Hye; Boyle, Elizabeth Heger

2015-01-01

The implementation of criminal law involves formal law enforcement, education and public outreach aimed at preventing criminal activity, and providing services for victims. Historically, quantitative research on global trends has tended to focus on a single policy dimension, potentially masking the unique factors that affect the diffusion of each policy dimension independently. Using an ordered-probit model to analyze new human trafficking policy data on national prosecution, prevention, and victim-protection efforts, we find that global ties and domestic interest groups matter more in areas where international law is less defined. While prosecution, officially mandated by the Trafficking Protocol, was relatively impervious to global ties and domestic interest groups, both trafficking prevention and victim protection were associated with these factors. Our findings also suggest that fear of repercussions is not a major driver of state actions to combat trafficking-neither ratification of the Trafficking Protocol nor levels of United States aid were associated with greater implementation of anti-trafficking measures.

Emerging research suggests that sex traffickers/pimps control the majority of trafficked girls in the United States. The youthfulness of these victims and their lack of psychosocial maturity severely diminish their ability to detect exploitative motives or withstand manipulation of traffickers. A review of 43 cases of sexually exploited girls involving non-relative traffickers and 10 semi-structured interviews with social service providers revealed numerous scripts and schemes used by sex traffickers to entrap and entangle victims including boyfriend/lover scripts, ruses involving debt bondage, friendship or faux-family scripts, threats of forced abortion or to take away children, and coerced co-offending. These findings inform potential prevention efforts and highlight the need for multi-systemic, victim-centered approaches to intervention. © The Author(s) 2014.

'Trafficking' or 'personal use': do people who regularly inject drugs understand Australian drug trafficking laws?

Science.gov (United States)

Hughes, Caitlin E; Ritter, Alison; Cowdery, Nicholas; Sindicich, Natasha

2014-11-01

Legal thresholds for drug trafficking, over which possession of an illicit drug is deemed 'trafficking' as opposed to 'personal use', are employed in all Australian states and territories excepting Queensland. In this paper, we explore the extent to which people who regularly inject drugs understand such laws. Participants from the seven affected states/territories in the 2012 Illicit Drug Reporting System (n = 823) were asked about their legal knowledge of trafficking thresholds: whether, if arrested, quantity possessed would affect legal action taken; and the quantities of heroin, methamphetamine, cocaine and cannabis that would constitute an offence of supply. Data were compared against the actual laws to identify the accuracy of knowledge by drug type and state, and sociodemographics, use and purchasing patterns related to knowledge. Most Illicit Drug Reporting System participants (77%) correctly said that quantity possessed would affect charge received. However, only 55.8% nominated any specific quantity that would constitute an offence of supply, and of those 22.6% nominated a wrong quantity, namely a quantity that was larger than the actual quantity for supply (this varied by state and drug). People who regularly inject drugs have significant gaps in knowledge about Australian legal thresholds for drug trafficking, particularly regarding the actual threshold quantities. This suggests that there may be a need to improve education for this population. Necessity for accurate knowledge would also be lessened by better design of Australian drug trafficking laws. © 2014 Australasian Professional Society on Alcohol and other Drugs.

To examine the link between human trafficking of minors and childhood adversity. We compared the prevalence of adverse childhood experiences (ACEs) and cumulative childhood adversity (ACE score) among a sample of 913 juvenile justice-involved boys and girls in Florida for whom the Florida child abuse hotline accepted human trafficking abuse reports between 2009 and 2015 with those of a matched sample. ACE composite scores were higher and 6 ACEs indicative of child maltreatment were more prevalent among youths who had human trafficking abuse reports. Sexual abuse was the strongest predictor of human trafficking: the odds of human trafficking was 2.52 times greater for girls who experienced sexual abuse, and there was a 8.21 times greater risk for boys who had histories of sexual abuse. Maltreated youths are more susceptible to exploitation in human trafficking. Sexual abuse in connection with high ACE scores may serve as a key predictor of exploitation in human trafficking for both boys and girls.

Accountability and the Use of Raids to Fight Trafficking

Directory of Open Access Journals (Sweden)

Melissa Ditmore

2012-06-01

Full Text Available Accountability in anti-trafficking efforts is a crucial but often overlooked aspect of deciding whether such efforts are truly rooted in a human rights framework. In a rush to help, and inspired by sensationalised views of what human trafficking is, many campaigns actually harm the very people they are supposed to assist. Law enforcement raids are one such effort, as they do not take into account the very different power dynamics between the actor engaging in the raid, and the person who is subject to the raid. Data from the United States suggests that raids conducted by local law enforcement agencies are an ineffective means of locating and identifying trafficked persons. Research also reveals that raids are all too frequently accompanied by violations of the human rights of trafficked persons and sex workers alike, and can therefore be counterproductive to the underlying goals of anti-trafficking initiatives. Findings suggest that a rights-based and “survivor-centred” approach to trafficking in persons requires the development and promotion of alternative methods of identifying and protecting the rights of trafficked persons which prioritise the needs, agency, and self-determination of trafficking survivors. They also indicate that preventative approaches, which address the circumstances that facilitate trafficking in persons, should be pursued over law enforcement based responses.

Child Labor Trafficking in the United States: A Hidden Crime

Directory of Open Access Journals (Sweden)

Katherine Kaufka Walts

2017-06-01

Full Text Available Emerging research brings more attention to labor trafficking in the United States. However, very few efforts have been made to better understand or respond to labor trafficking of minors. Cases of children forced to work as domestic servants, in factories, restaurants, peddling candy or other goods, or on farms may not automatically elicit suspicion from an outside observer as compared to a child providing sexual services for money. In contrast to sex trafficking, labor trafficking is often tied to formal economies and industries, which often makes it more difficult to distinguish from "legitimate" work, including among adolescents. This article seeks to provide examples of documented cases of child labor trafficking in the United States, and to provide an overview of systemic gaps in law, policy, data collection, research, and practice. These areas are currently overwhelmingly focused on sex trafficking, which undermines the policy intentions of the Trafficking Victims Protection Act (2000, the seminal statute criminalizing sex and labor trafficking in the United States, its subsequent reauthorizations, and international laws and protocols addressing human trafficking.

Full Text Available Trafficking has existed since the period of kingdoms in Java, going on to the colonialism period, andto the present time. Its meaning is broadening beyond human trading into the matters related to violence,blackmailing, and forcing. Trafficking happens not only within one specific area, but has crossed theborder of countries, indicating the existence of an international net. The mushrooming of trafficking isdue to weak law and political commitment of the concerning countries. Moreover, the bilateral talk tobanish trafficking has not been maximally conducted. The actors of trafficking vary from man-powerbrokers, agents, taxi drivers, and even officers (of transmigration and police offices. Trafficking happens invarious places ranging from luxurious spots or starred-hotels to plantations and areas which accommodatea lot of migrants. The victims are usually in so unfavorable bargaining positions that they are muchdependent on those traffickers. This dependency is the impact of imbalanced gender relation. Based onsome existing cases, it is indicated that the women’s lack of power, strength, information, and educationare often misused by the traffickers to take them as their preys. That is why empowering migrant womenis very crucial. One of the ways is empowering them through their realization that this need comes fromtheir own selves, not from any force outside. Besides, there should be strong commitment from the stateto seriously implement the law against any traffickers. Cooperation between the concerning countriesare also needed, for instance by issuing common regulations to banish trafficking.Keywords: Trafficking, migrant women, receiving country, sending country, trafficker

An estimated 18,000 individuals are trafficked into the United States each year from all over the world, and are forced into hard labor or commercial sex work. Despite their invisibility, some victims are known to have received medical care while under traffickers' control. Our project aimed to characterize trafficking victims' encounters in US health care settings. The study consisted of semi-structured interviews with six Key Informants who work closely with trafficking victims (Phase I) and 12 female trafficking survivors (Phase II). All survivors were recruited through the Coalition to Abolish Slavery and Trafficking, an NGO in Los Angeles, and all were trafficked into Los Angeles. Interviews were conducted in English and six other languages, with the assistance of professional interpreters. Using a framework analysis approach that focused on victims' encounters in health care settings, we assessed interview transcript content and coded for themes. We used an exploratory pile-sorting technique to aggregate similar ideas and identify overarching domains. The survivors came from 10 countries. Eight had experienced domestic servitude, three had survived sex trafficking, and one had experienced both. Half the survivors reported that they had visited a physician while in their traffickers' control, and another worked in a health care facility. All Key Informants described other victims who had received medical care. For domestic servants, medical visits were triggered by injury and respiratory or systemic illness, while sex trafficking victims were seen by health professionals for sexually transmitted infections and abortion. Trafficking victims were prevented from disclosing their status to health care providers by fear, shame, language barriers, and limited interaction with medical personnel, among other obstacles. This exploration of survivors' experiences in health care settings supports anecdotal reports that US health care providers may unwittingly encounter

Entamoeba histolytica is an intestinal parasite that infects 50-100 million people and causes up to 55,000 deaths annually. The transmissive form of E. histolytica is the cyst, with a single infected individual passing up to 45 million cysts per day, making cyst production an attractive target for infection control. Lectins and chitin are secreted to form the cyst wall, although little is known about the underlying membrane trafficking processes supporting encystation. As E. histolytica does not readily form cysts in vitro, we assessed membrane trafficking gene expression during encystation in the closely related model Entamoeba invadens. Genes involved in secretion are up-regulated during cyst formation, as are some trans-Golgi network-to-endosome trafficking genes. Furthermore, endocytic and general trafficking genes are up-regulated in the mature cyst, potentially preserved as mRNA in preparation for excystation. Two divergent dynamin-related proteins found in Entamoeba are predominantly expressed during cyst formation. Phylogenetic analyses indicate that they are paralogous to, but quite distinct from, classical dynamins found in human, suggesting that they may be potential drug targets to block encystation. The membrane-trafficking machinery is clearly regulated during encystation, providing an additional facet to understanding this crucial parasitic process.

KENYA’S CONSTITUTION AND CHILD TRAFFICKING AS A SECURITY THREAT

Full Text Available Human trafficking also referred to as modern-day slavery is seen as a security threat. Traditional security approaches to human trafficking call for analysis of trafficking as a threat to the Kenyan state and to Kenya’s control of its borders. Traditional security analyses of trafficking emphasize border security, migration controls, and international law enforcement cooperation. This article discusses three forms of child trafficking: sexual exploitation, forced labor and child soldiers and argues that the newly promulgated Kenyan constitution in chapter three on citizenship has a provision that can be interpreted as encouraging child trafficking.

The topic of child sex trafficking is receiving increased attention both in the lay press and in research articles. Recently, a number of physician organizations have issued policy statements calling for the education and involvement of physicians in combating this form of "modern-day slavery." Primary care and emergency medicine physicians have led these efforts, but a number of these victims may present to surgeons. Surgeons are in a unique position to identify trafficked patients; during the process of undraping, intubation, and surgical preparation, signs of trafficking such as tattoos, scars, dental injuries, and bruising may be evident. In addition, these patients may have specific needs in terms of anesthesia and postoperative care due to substance abuse. Here, we report the case of an 18-year-old girl with a history of sexual exploitation who presents for cystadenoma excision. To our knowledge, this is the first report of a sex-trafficked pediatric patient presenting for surgery. Copyright © 2016 by the American Academy of Pediatrics.

Devastating consequences of sex trafficking on women's health.

McTavish, Fr James

2017-11-01

Sex trafficking has devastating consequences on the physical and mental well-being of millions of women around the world. These trafficking victims often come in contact with medical personnel, and these encounters with suitably prepared staff can be a step toward healing of the victims. The Catholic Church, especially through Pope Francis, is making strenuous efforts to curb the spread of sex trafficking. Same-sex feelings and behavior may arise post-trafficking in individuals, although this does not appear to be mentioned thus far in the literature. Here, we are most likely dealing with a type of "pseudo-lesbianism" post-trauma. The trafficking survivor can be helped to understand some of the likely roots of her feelings such as anti-male sentiments following abuse. She needs to be patiently, and expertly, accompanied to process the trauma she has experienced, and learn how to meet her genuine needs for female affection and affirmation in healthy, chaste, and non-erotic ways. Around the world, millions of female victims of human trafficking are forced into sex "work," often resulting in serious physical and mental-health problems. Healthcare staff should be alert to spot victims of sex trafficking and be ready to assist them. The Catholic Church, especially through Pope Francis, has been vocal in denouncing this form of modern slavery. Some female victims of sex trafficking may experience same-sex feelings afterward. Healing for such young women involves helping them to process their traumatic experiences, as well as patiently accompanying them as they seek to develop healthy, chaste friendships with other females and males.

Debate: Strategically Working in Parallel to Traffickers

2014-09-01

Full Text Available Let’s be realistic, counter-trafficking teams will never be as effective as the proactive and flexible networks of outlaws that violate the rights of millions of people each year. The ‘bad guys’ operate without the same financial limitations such as bureaucratic red tape and donor criteria, and take advantage of patchy and often uncoordinated border surveillance that is chronically untrained in detecting trafficking in persons.  Non-governmental organisations (NGOs involved in the fight against human trafficking—and in direct contact with presumed victims (their status is not assessed until at a stage later than this initial contact—are in a diametrically opposite situation. They must carefully abide by the national and international legal frameworks that their criminal antagonists ignore. Donors and national authorities operate within the constraints of geographic target areas and funding cycles. Since counter-trafficking actors neither create the markets nor devise the routes for trafficking, their strategic cross-border (or long distance partnerships are always a few steps behind the traffickers, if not many steps behind, and rarely efficient.

Full Text Available Recent findings have indicated that both in-country trafficking (trafficking of individuals from rural areas to relatively affluent towns and cities and external trafficking (trafficking of individuals from a given country to foreign countries are prevalent in Ethiopia. In 2012, the government acceded to the Protocol to Suppress and Punish Trafficking in Persons Especially Women and Children supplementing the United Nations Convention against Transnational Organized Crime (The UN Trafficking Protocol, here after. With a view to giving effect to the requirements of this instrument, the government passed in to law Proclamation No. 909/2015 (The Prevention and Suppression of Trafficking in Persons and Smuggling of Migrants Proclamation, which is the most comprehensive of all laws adopted in Ethiopia to deal with human trafficking. Taking in to account the fact that human trafficking is exacerbated by the absence of regulatory framework on the employment of Ethiopian nationals in foreign countries, the govern-ment has also brought in to practice Proclamation No. 923/2016 (Ethiopia’s Overseas Employment Proclamation. This article has examined whether the above-mentioned laws of Ethiopia comply with international standards in dealing with prevention strategies.

Trafficking regulates the subcellular distribution of voltage-gated sodium channels in primary sensory neurons.

Science.gov (United States)

Bao, Lan

2015-09-30

Voltage-gated sodium channels (Navs) comprise at least nine pore-forming α subunits. Of these, Nav1.6, Nav1.7, Nav1.8 and Nav1.9 are the most frequently studied in primary sensory neurons located in the dorsal root ganglion and are mainly localized to the cytoplasm. A large pool of intracellular Navs raises the possibility that changes in Nav trafficking could alter channel function. The molecular mediators of Nav trafficking mainly consist of signals within the Navs themselves, interacting proteins and extracellular factors. The surface expression of Navs is achieved by escape from the endoplasmic reticulum and proteasome degradation, forward trafficking and plasma membrane anchoring, and it is also regulated by channel phosphorylation and ubiquitination in primary sensory neurons. Axonal transport and localization of Navs in afferent fibers involves the motor protein KIF5B and scaffold proteins, including contactin and PDZ domain containing 2. Localization of Nav1.6 to the nodes of Ranvier in myelinated fibers of primary sensory neurons requires node formation and the submembrane cytoskeletal protein complex. These findings inform our understanding of the molecular and cellular mechanisms underlying Nav trafficking in primary sensory neurons.

Voltage-gated Ca(2+) channels play a key role in initiating muscle excitation-contraction coupling, neurotransmitter release, gene expression, and hormone secretion. The association of CaV1.2 with a supramolecular complex impacts trafficking, localization, turnover, and, most importantly, multifaceted regulation of its function in the heart. Several studies hint at an important role for the C terminus of the α1C subunit as a hub for multidimensional regulation of CaV1.2 channel trafficking and function. Recent studies have demonstrated an important role for the four-residue PDZ binding motif at the C terminus of α1C in interacting with scaffold proteins containing PDZ domains, in the subcellular localization of CaV1.2 in neurons, and in the efficient signaling to cAMP-response element-binding protein in neurons. However, the role of the α1C PDZ ligand domain in the heart is not known. To determine whether the α1C PDZ motif is critical for CaV1.2 trafficking and function in cardiomyocytes, we generated transgenic mice with inducible expression of an N-terminal FLAG epitope-tagged dihydropyridine-resistant α1C with the PDZ motif deleted (ΔPDZ). These mice were crossed with α-myosin heavy chain reverse transcriptional transactivator transgenic mice, and the double-transgenic mice were fed doxycycline. The ΔPDZ channels expressed, trafficked to the membrane, and supported robust excitation-contraction coupling in the presence of nisoldipine, a dihydropyridine Ca(2+) channel blocker, providing functional evidence that they appropriately target to dyads. The ΔPDZ Ca(2+) channels were appropriately regulated by isoproterenol and forskolin. These data indicate that the α1C PDZ motif is not required for surface trafficking, localization to the dyad, or adrenergic stimulation of CaV1.2 in adult cardiomyocytes. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

Trafficking in women and children is a gross violation of human rights. However, this does not prevent an estimated 800 000 women and children to be trafficked each year across international borders. Eighty per cent of trafficked persons end in forced sex work. India has been identified as one of the Asian countries where trafficking for commercial sexual exploitation has reached alarming levels. While there is a considerable amount of internal trafficking from one state to another or within states, India has also emerged as a international supplier of trafficked women and children to the Gulf States and South East Asia, as well as a destination country for women and girls trafficked for commercial sexual exploitation from Nepal and Bangladesh. Trafficking for commercial sexual exploitation is a highly profitable and low risk business that preys on particularly vulnerable populations. This paper presents an overview of the trafficking of women and girls for sexual exploitation (CSE) in India; identifies the health impacts of CSE; and suggest strategies to respond to trafficking and related issues.

Human organic anion transporting polypeptides (OATPs) mediate the influx of many important drugs into cells. Casein kinase 2 (CK2) is a critical protein kinase that phosphorylates >300 protein substrates and is dysregulated in a number of disease states. Among the CK2 substrates are several transporters, although whether this includes human OATPs has not been evaluated. The current study was undertaken to evaluate the regulation of human OATP1A2 by CK2. HEK-239T cells in which OATP1A2 was overexpressed were treated with CK2 specific inhibitors or transfected with CK2 specific siRNA, and the activity, expression, and subcellular trafficking of OATP1A2 was evaluated. CK2 inhibition decreased the uptake of the prototypic OATP1A2 substrate estrone-3-sulfate (E3S). Kinetic studies revealed that this was due to a decrease in the maximum velocity (Vmax) of E3S uptake, while the Michaelis constant was unchanged. The cell surface expression, but not the total cellular expression of OATP1A2, was impaired by CK2 inhibition and knockdown of the catalytic α-subunits of CK2. CK2 inhibition decreased the internalization of OATP1A2 via a clathrin-dependent pathway, decreased OATP1A2 recycling, and likely impaired OATP1A2 targeting to the cell surface. Consistent with these findings, CK2 inhibition also disrupted the colocalization of OATP1A2 and Rab GTPase (Rab)4-, Rab8-, and Rab9-positive endosomal and secretory vesicles. Taken together, CK2 has emerged as a novel regulator of the subcellular trafficking and stability of OATP1A2. Because OATP1A2 transports many molecules of physiological and pharmacological importance, the present data may inform drug selection in patients with diseases in which CK2 and OATP1A2 are dysregulated.

hERG trafficking inhibition in drug-induced lethal cardiac arrhythmia.

Nogawa, Hisashi; Kawai, Tomoyuki

2014-10-15

Acquired long QT syndrome induced by non-cardiovascular drugs can cause lethal cardiac arrhythmia called torsades de points and is a significant problem in drug development. The prolongation of QT interval and cardiac action potential duration are mainly due to reduced physiological function of the rapidly activating voltage-dependent potassium channels encoded by human ether-a-go-go-related gene (hERG). Structurally diverse groups of drugs are known to directly inhibit hERG channel conductance. Therefore, the ability of acute hERG inhibition is routinely assessed at the preclinical stages in pharmaceutical testing. Recent findings indicated that chronic treatment with various drugs not only inhibits hERG channels but also decreases hERG channel expression in the plasma membrane of cardiomyocytes, which has become another concern in safety pharmacology. The mechanisms involve the disruption of hERG trafficking to the surface membrane or the acceleration of hERG protein degradation. From this perspective, we present a brief overview of mechanisms of drug-induced trafficking inhibition and pathological regulation. Understanding of drug-induced hERG trafficking inhibition may provide new strategies for predicting drug-induced QT prolongation and lethal cardiac arrhythmia in pharmaceutical drug development.

Human trafficking is a human rights violation prevalent globally. Current guidelines highlight healthcare professionals' key role in responding to human trafficking, emphasizing the importance of medical education in raising awareness of trafficking. To assess pre-clerkship medical students' awareness of human trafficking and attitudes towards learning about trafficking in the medical curriculum at Canada's largest medical school. An anonymous, classroom-based questionnaire was designed, piloted and administered to first- and second-year medical students at one large Canadian medical school with a diverse student population. The questionnaire sought demographic data and information on students' self-perceived awareness of human trafficking and interest in learning about trafficking and other community health issues. 262 medical students completed the questionnaire (70.0% response). Most participants reported that they were not knowledgeable (48.5%) or only somewhat knowledgeable (45.4%) about human trafficking. 88.9% of participants were not familiar with signs and symptoms of trafficked persons. While students' responses indicated that they prioritized other social issues, a majority of participants (76.0%) thought that trafficking was important to learn about in medical school, especially identifying trafficked persons and their health needs. These medical students of one Canadian medical school demonstrated limited familiarity with the issue of human trafficking but largely felt that they should be taught more about this issue during their medical education. This assessment of early medical students' awareness of human trafficking is relevant to medical educators and the organizations that could develop the required educational curricula and resources.

A Comparison of Psychological Symptoms in Survivors of Sex and Labor Trafficking.

Hopper, E K; Gonzalez, L D

2018-03-20

Human trafficking is a form of interpersonal trauma that has significant mental health impacts on survivors. This study examined psychological symptoms in 131 survivors of sex and labor trafficking, including people trafficked into or within the U.S. High rates of depression (71%) and PTSD (61%) were identified. Two thirds of survivors also met criteria for multiple categories of Complex PTSD (C-PTSD), including affect dysregulation and impulsivity; alterations in attention and consciousness; changes in interpersonal relationships; revictimization; somatic dysregulation; and alterations in self-perception. Although there were not significant differences in the prevalence rates of diagnoses of PTSD or depression between survivors of sex and labor trafficking, important group differences were identified. Compared to survivors of labor trafficking, sex trafficking survivors had higher prevalence rates of pre-trafficking childhood abuse and a higher incidence of physical and sexual violence during trafficking. They reported more severe post-trauma reactions than labor trafficking survivors, including more PTSD and C-PTSD symptoms. They were also more likely to meet criteria for comorbid PTSD and depression, while labor trafficking survivors were more likely than sex trafficking survivors to meet criteria for depression alone. An analysis of gender differences found that trafficking survivors who identified as transgender endorsed more PTSD and C-PTSD symptoms, than male or female survivors. Childhood abuse exposure was linked to PTSD and C-PTSD in trafficking survivors, and trafficking type was predictive of the number of trauma-related symptoms beyond the role of pre-trafficking child abuse. Implications for assessment and intervention with trafficking survivors are discussed.

The role of the nurse in combating human trafficking.

Human trafficking, also called modern slavery, happens worldwide--and the United States is no exception. Within our borders, thousands of foreign nationals and U.S. citizens, many of them children, are forced or coerced into sex work or various forms of labor every year. Nurses and other health care providers who encounter victims of trafficking often don't realize it, and opportunities to intervene are lost. Although no one sign can demonstrate with certainty when someone is being trafficked, there are several indicators that clinicians should know. This article provides an overview of human trafficking, describes how to recognize signs that a person is being trafficked and how to safely intervene, and offers an extensive resource list.

Female trafficking is a social and public health problem, associated with physical and sexual abuse, psychological trauma, injuries from violence, sexually transmitted infections, adverse reproductive outcomes and substance misuse. It faces several challenges ranging from the hidden nature of the problem to ethical and human rights issues. The objectives of this paper are to analyze health impact of trafficking; ethical and research issues and anti-trafficking strategies in the Nepalese context. We collected published and unpublished data assessing the public health, ethical burden and research needs from different sources. Trafficked female involved in sex-industry that face grave situation as depicted and it might a reservoir of sexually transmitted diseases. Ethical issues related to survey of assessing the burden are difficult to carry out. The best ways to prevent and control these problems are to enhance anti- trafficking laws and raise awareness, empower and mobilize females and establish organizational capacity.

Captured ‘Realities’ of Human Trafficking: Analysis of photographs illustrating stories on trafficking into the sex industry in Serbian media

Directory of Open Access Journals (Sweden)

Elena Krsmanovic

2016-09-01

Full Text Available Past research has looked at how the media frames human trafficking, but has seldom included analysis of visual representations. To bridge this gap, this paper scrutinises stereotypical representations of persons trafficked into the sex industry in photographs published in Serbian online media from 2011 to 2014. To uncover characteristics of dominant tropes in this sample, a method of semiotic analysis is applied. The analysis argues that images are dominated by portrayals of trafficked persons that fit into one of two frames: powerless victim or unworthy prostitute. Male figures are rarely presented in these photographs, but when present, they are shown to hurt or control the women depicted alongside them. Chains, padlocks, barcodes, whip marks, and other symbols associated with slavery are present to a lesser extent. However, they testify to the tendency to link human trafficking to slavery and to use the moral potential of the anti-slavery rhetoric. Photographs are too easily seen as authentic, factual transcripts of reality. This paper suggests that these images tell us more about societal fear of insecurity, ideas about gender, erotic obsessions and morality than about human trafficking itself. It also argues that the meaning of trafficking is shaped by the deeply embedded codes of patriarchy and hidden misogyny present in Serbian society.

Disruption of endolysosomal trafficking pathways in glioma cells by methuosis-inducing indole-based chalcones.

Mbah, Nneka E; Overmeyer, Jean H; Maltese, William A

2017-06-01

Methuosis is a form of non-apoptotic cell death involving massive vacuolization of macropinosome-derived endocytic compartments, followed by a decline in metabolic activity and loss of membrane integrity. To explore the induction of methuosis as a potential therapeutic strategy for killing cancer cells, we have developed small molecules (indole-based chalcones) that trigger this form of cell death in glioblastoma and other cancer cell lines. Here, we report that in addition to causing fusion and expansion of macropinosome compartments, the lead compound, 3-(5-methoxy-2-methyl-1H-indol-3-yl)-1-(4-pyridinyl)-2-propen-1-one (MOMIPP), disrupts vesicular trafficking at the lysosomal nexus, manifested by impaired degradation of EGF and LDL receptors, defective processing of procathepsins, and accumulation of autophagosomes. In contrast, secretion of the ectodomain derived from a prototypical type-I membrane glycoprotein, β-amyloid precursor protein, is increased rather than diminished. A closely related MOMIPP analog, which causes substantial vacuolization without reducing cell viability, also impedes cathepsin processing and autophagic flux, but has more modest effects on receptor degradation. A third analog, which causes neither vacuolization nor loss of viability, has no effect on endolysosomal trafficking. The results suggest that differential cytotoxicity of structurally similar indole-based chalcones is related, at least in part, to the severity of their effects on endolysosomal trafficking pathways.

Complex lipid trafficking in Niemann-Pick disease type C.

Science.gov (United States)

Vanier, Marie T

2015-01-01

Niemann-Pick disease type C (NPC) is an atypical lysosomal storage disease resulting from mutations in one of two genes, either NPC1 or NPC2. Although a neurovisceral disorder, it is above all a neurodegenerative disease in the vast majority of patients. Not an enzyme deficiency, it is currently conceived as a lipid trafficking disorder. Impaired egress of cholesterol from the late endosomal/lysosomal (LE/L) compartment is a specific and key element of the pathogenesis, but other lipids, more specially sphingolipids, are also involved, and there are indications for further abnormalities. The full function of the NPC1 and NPC2 proteins is still unclear. This review provides a reappraisal of lipid storage and lysosomal enzymes activities in tissues/cells from NPC patients and animal models. It summarizes the current knowledge on the NPC1 and NPC2 proteins and their function in transport of cholesterol within the late endosomal-lysosomal compartment, with emphasis on differences between systemic organs and the brain; it also discusses regulation by membrane lipids of the NPC2-mediated cholesterol trafficking, interplay between cholesterol and sphingomyelin, the metabolic origin of glycosphingolipids stored in brain, and the putative role of free sphingoid bases in pathogenesis. Brief mention is finally made of diseases affecting other genes that were very recently shown to impact the "NPC pathway".

2017-02-01

Our aim was to assess: (1) medical trainee and practicing physician awareness about domestic sex trafficking of minors; and (2) whether respondents believe that awareness of trafficking is important to their practice. We designed an anonymous electronic survey, and a convenience sample was collected from June through October 2013. Voluntary participants were 1648 medical students, residents, and practicing physicians throughout the United States. Data were analyzed for correlations between study cohort characteristics and: (1) agreement with the statement: "knowing about sex trafficking in my state is important to my profession"; (2) knowledge of national statistics regarding the sex trafficking of minors; and (3) knowledge of appropriate responses to encountering a trafficked victim. More practicing physicians than residents or medical students: (1) agreed or strongly agreed that knowledge about human trafficking was important to their practice (80.6%, 71.1%, and 69.2%, respectively; P = .0008); (2) correctly estimated the number of US trafficked youth according to the US Department of State data (16.1%, 11.7%, and 7.9%, respectively; P = .0011); and (3) were more likely to report an appropriate response to a trafficked victim (40.4%, 20.4%, and 8.9%, respectively; P = .0001). Although most medical trainees and physicians place importance on knowing about human trafficking, they lack knowledge about the scope of the problem, and most would not know where to turn if they encountered a trafficking victim. There exists a need for standardized trafficking education for physicians, residents, and medical students. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology.

Sphingomyelin synthases regulate protein trafficking and secretion.

Directory of Open Access Journals (Sweden)

Marimuthu Subathra

Full Text Available Sphingomyelin synthases (SMS1 and 2 represent a class of enzymes that transfer a phosphocholine moiety from phosphatidylcholine onto ceramide thus producing sphingomyelin and diacylglycerol (DAG. SMS1 localizes at the Golgi while SMS2 localizes both at the Golgi and the plasma membrane. Previous studies from our laboratory showed that modulation of SMS1 and, to a lesser extent, of SMS2 affected the formation of DAG at the Golgi apparatus. As a consequence, down-regulation of SMS1 and SMS2 reduced the localization of the DAG-binding protein, protein kinase D (PKD, to the Golgi. Since PKD recruitment to the Golgi has been implicated in cellular secretion through the trans golgi network (TGN, the effect of down-regulation of SMSs on TGN-to-plasma membrane trafficking was studied. Down regulation of either SMS1 or SMS2 significantly retarded trafficking of the reporter protein vesicular stomatitis virus G protein tagged with GFP (VSVG-GFP from the TGN to the cell surface. Inhibition of SMSs also induced tubular protrusions from the trans Golgi network reminiscent of inhibited TGN membrane fission. Since a recent study demonstrated the requirement of PKD activity for insulin secretion in beta cells, we tested the function of SMS in this model. Inhibition of SMS significantly reduced insulin secretion in rat INS-1 cells. Taken together these results provide the first direct evidence that both enzymes (SMS1 and 2 are capable of regulating TGN-mediated protein trafficking and secretion, functions that are compatible with PKD being a down-stream target for SMSs in the Golgi.

Effectiveness of Counter-Trafficking Response in Albania

Meçe Merita H.

2016-07-01

Full Text Available Human trafficking is a new phenomenon of Albanian post-socialist society which significantly increased during the difficult years of its transformation from centralized state-led economy to market economy. Both economic and political instability contributed to its size, nature and multiple dynamics. Drawing on a rights-based approach to human trafficking, this paper examines the effectiveness of the counter-trafficking response of the Albanian government with a special emphasis on prevention, protection and prosecution. Using secondary data and reviewing various country strategic documents, it highlights a range of weaknesses and challenges which have hindered its effectiveness over years. It concludes that successful and effective counter-trafficking response requires well rounded and coordinated gender sensitive, victim-centred, holistic and human rights-based efforts. Combined with adequate law enforcement, they will sustainably tackle the full spectrum of this problem.

Decreasing Human Trafficking through Sex Work Decriminalization.

In order to decrease human trafficking, health care workers should support the full decriminalization of prostitution. Similar to trafficking in other forms of labor, preventing trafficking in the sex trade requires addressing the different forms of marginalization that create vulnerable communities. By removing punitive laws that prevent reporting of exploitation and abuse, decriminalization allows sex workers to work more safely, thereby reducing marginalization and vulnerability. Decriminalization can also help destigmatize sex work and help resist political, social, and cultural marginalization of sex workers. © 2017 American Medical Association. All Rights Reserved.

Full Text Available Large numbers of Indonesian men migrate each year for work in construction, in factories and in agriculture, on plantations and on fishing boats. Many of them end up exploited in ways that constitute human trafficking, suffering violence, deprivation, restricted freedom and severe exploitation as well as long periods of separation from their families. This article explores the challenges faced by forty-nine Indonesian men reintegrating into their families and communities after having been trafficked. While many problems with the family were caused by economics, tensions also resulted from long separations, fractured relationships, and frustration and blame over ‘failed’ migration and unfulfilled expectations. Tensions were sometimes exacerbated when men faced recrimination and blame in their communities after return. Understanding the nature of and reasons for the problems that men faced after trafficking is vital in considering how trafficked men and their families can be supported to recover and reintegrate after trafficking.

P-glycoprotein (Pgp; ABCB1/MDR1) is a major efflux transporter at the blood-brain barrier (BBB), restricting the penetration of various compounds. In other tissues, trafficking of Pgp from subcellular stores to the cell surface has been demonstrated and may constitute a rapid way of the cell to respond to toxic compounds by functional membrane insertion of the transporter. It is not known whether drug-induced Pgp trafficking also occurs in brain capillary endothelial cells that form the BBB. In this study, trafficking of Pgp was investigated in human brain capillary endothelial cells (hCMEC/D3) that were stably transfected with a doxycycline-inducible MDR1-EGFP fusion plasmid. In the presence of doxycycline, these cells exhibited a 15-fold increase in Pgp-EGFP fusion protein expression, which was associated with an increased efflux of the Pgp substrate rhodamine 123 (Rho123). The chemotherapeutic agent mitomycin C (MMC) was used to study drug-induced trafficking of Pgp. Confocal fluorescence microscopy of single hCMEC/D3-MDR1-EGFP cells revealed that Pgp redistribution from intracellular pools to the cell surface occurred within 2 h of MMC exposure. Pgp-EGFP exhibited a punctuate pattern at the cell surface compatible with concentrated regions of the fusion protein in membrane microdomains, i.e., lipid rafts, which was confirmed by Western blot analysis of biotinylated cell surface proteins in Lubrol-resistant membranes. MMC exposure also increased the functionality of Pgp as assessed in three functional assays with Pgp substrates (Rho123, eFluxx-ID Gold, calcein-AM). However, this increase occurred with some delay after the increased Pgp expression and coincided with the release of Pgp from the Lubrol-resistant membrane complexes. Disrupting rafts by depleting the membrane of cholesterol increased the functionality of Pgp. Our data present the first direct evidence of drug-induced Pgp trafficking at the human BBB and indicate that Pgp has to be released from lipid

The prototypic betaherpesvirus human cytomegalovirus (CMV) establishes life-long persistence within its human host. While benign in healthy individuals, CMV poses a significant threat to the immune compromised, including transplant recipients and neonates. The CMV glycoprotein complex gH/gL/gO mediates infection of fibroblasts, and together with the gH/gL/UL128/130/131 a pentameric complex permits infection of epithelial, endothethial, and myeloid cells. Given the central role of the gH/gL complex during infection, we were interested in studying cellular trafficking of the gH/gL complex through generation of human cells that stably express gH and gL. When expressed alone, CMV gH and gL were degraded through the ER-associated degradation (ERAD) pathway. However, co-expression of these proteins stabilized the polypeptides and enhanced their cell-surface expression. To further define regulatory factors involved in gH/gL trafficking, a CMV gH chimera in which the gH transmembrane and cytoplasmic tail were replaced with that of human CD4 protein permitted cell surface gH expression in absence of gL. We thus demonstrate the ability of distinct cellular processes to regulate the trafficking of viral glycoproteins. Collectively, the data provide insight into the processing and trafficking requirements of CMV envelope protein complexes and provide an example of the co-opting of cellular processes by CMV.

Illicit trafficking of radiological and nuclear materials: modeling and analysis of trafficking trends and risks

International Nuclear Information System (INIS)

York, David L.; Love, Tracia L.; Rochau, Gary Eugene

2005-01-01

Concerns over the illicit trafficking of radiological and nuclear materials were focused originally on the lack of security and accountability of such material throughout the former Soviet states. This is primarily attributed to the frequency of events that have occurred involving the theft and trafficking of critical material components that could be used to construct a Radiological Dispersal Device (RDD) or even a rudimentary nuclear device. However, with the continued expansion of nuclear technology and the deployment of a global nuclear fuel cycle these materials have become increasingly prevalent, affording a more diverse inventory of dangerous materials and dual-use items. To further complicate the matter, the list of nuclear consumers has grown to include: (1) Nation-states that have gone beyond the IAEA agreed framework and additional protocols concerning multiple nuclear fuel cycles and processes that reuse the fuel through reprocessing to exploit technologies previously confined to the more industrialized world; (2) Terrorist organizations seeking to acquire nuclear and radiological material due to the potential devastation and psychological effect of their use; (3) Organized crime, which has discovered a lucrative market in trafficking of illicit material to international actors and/or countries; and (4) Amateur smugglers trying to feed their families in a post-Soviet era. An initial look at trafficking trends of this type seems scattered and erratic, localized primarily to a select group of countries. This is not necessarily the case. The success with which other contraband has been smuggled throughout the world suggests that nuclear trafficking may be carried out with relative ease along the same routes by the same criminals or criminal organizations. Because of the inordinately high threat posed by terrorist or extremist groups acquiring the ingredients for unconventional weapons, it is necessary that illicit trafficking of these materials be better

Identification and Management of Human Trafficking Victims in the Emergency Department.

Hachey, Lisa M; Phillippi, Julia C

Health care practitioners serve an important role in identification and assistance of human trafficking victims. Advanced practice registered nurses, including certified nurse midwives, clinical nurse specialists, and nurse practitioners, are in a unique position to interact with persons trafficked and seen in the clinical setting, yet they require knowledge to identify the signs of human trafficking. Lack of training and education has been identified as a barrier for health care professionals to recognize human trafficking victims and implement needed health care services (; ). Barriers to identification and management include gap in knowledge about the process to screen for trafficking, to assist victims, and to make referrals. A patient-centered, trauma-informed approach can provide a safe environment to sensitively screen patients for human trafficking. Advanced practice registered nurses should be able to assess for trafficking indicators, collaborate with multidisciplinary service providers, and ensure understanding and availability of federal, state, and local resources to manage the care of victims of trafficking.

Trafficking in human beings is a modern form of slavery and is a well-known phenomenon throughout the European Union and beyond. After drug dealing and the weapons industry, human trafficking is the second largest criminal activity in the world today and it is a growing crime. The aim of governmental and non-governmental agencies, which are either directly or indirectly involved in combating trafficking in human beings, is the identification and referral of victims of trafficking and also to encourage self-referrals. Identification is the most important step to provide protection and assistance to victims of trafficking. Victims often have a variety of physical and mental health needs, including psychological trauma, injuries from violence, head and neck trauma, sexually transmitted infections and other gynaecological problems, dental/oral problems and have poor nutrition. The author's experience in the field of community dentistry in presented within. Volunteer dental services are offered to non-European Union patients held in a centre for asylum seekers in Bari (Italy). Dental professionals can, in fact, contribute to the identification, assistance and protection of trafficked persons, as well as offering forensic services to assist the police investigation in order to identify crimes and find the criminal organizations behind them. As for domestic violence and child abuse cases, there are ethical concerns involved in the identification and protection of the trafficked persons, as well as the need for interdisciplinary work and awareness. Adequate training in behavioural science and intercultural learning is paramount in order to avoid misunderstandings and increase sensitivity.

2018-02-01

Weapons related webpages from nine cryptomarkets were manually duplicated in February 2016. Information about the listings (i.e. sales proposals) and vendors' profiles were extracted to draw an overview of the actual online trafficking of weapons. Relationships between vendors were also inferred through the analysis of online digital traces and content similarities. Weapons trafficking is mainly concentrated on two major cryptomarkets. Besides, it accounts for a very small proportion of the illicit trafficking on cryptomarkets compared to the illicit drugs trafficking. Among all weapon related listings (n=386), firearms only account for approximately 25% of sales proposal since the proportion of non-lethal and melee weapons is important (around 46%). Based on the recorded pseudonyms, a total of 96 vendor profiles were highlighted. Some pseudonyms were encountered on several cryptomarkets, suggesting that some vendors may manage accounts on different markets. This hypothesis was strengthened by comparing pseudonyms to online traces such as PGP keys, images and profiles descriptions. Such a method allowed to estimate more accurately the number of vendors offering weapons across cryptomarkets. Finally, according to the gathered data, the extent of the weapons trafficking on the cryptomarkets appear to be limited compared to other illicit goods. Copyright © 2017 Elsevier B.V.

Adaptor protein complex 1 (AP-1) is an evolutionary conserved heterotetramer that promotes vesicular trafficking between the trans-Golgi network and the endosomes. The knockout of most murine AP-1 complex subunits is embryonically lethal, so the identification of human disease-associated alleles has the unique potential to deliver insights into gene function. Here, we report two founder mutations (c.11T>G [p.Phe4Cys] and c.97C>T [p.Arg33Trp]) in AP1S3, the gene encoding AP-1 complex subunit σ1C, in 15 unrelated individuals with a severe autoinflammatory skin disorder known as pustular psoriasis. Because the variants are predicted to destabilize the 3D structure of the AP-1 complex, we generated AP1S3-knockdown cell lines to investigate the consequences of AP-1 deficiency in skin keratinocytes. We found that AP1S3 silencing disrupted the endosomal translocation of the innate pattern-recognition receptor TLR-3 (Toll-like receptor 3) and resulted in a marked inhibition of downstream signaling. These findings identify pustular psoriasis as an autoinflammatory phenotype caused by defects in vesicular trafficking and demonstrate a requirement of AP-1 for Toll-like receptor homeostasis.

2010-08-01

Since the passing of the Victims of Trafficking and Violence Protection Act in 2000 and its reauthorization by President George Bush in 2008, federal, state and community efforts in identifying and providing services for victims of human trafficking have significantly improved. However, most of the research and resources for trafficking victims have been directed towards adults rather than children. Researchers agree that there is a growing number of sexually exploited and trafficked children in the United States yet few programs emphasize the unique experiences and special needs of this population. This article examines commercial sexual exploitation of children; differentiates the needs and problems between child prostitution and victims of human trafficking; reviews and critiques current treatment practices; and summarizes challenges and successes in working with child victims of human trafficking, offering practice and policy recommendations.

This study aimed to build the evidence base around human trafficking (HT) and health in the U.S. by employing a quantitative approach to exploring the notion that health care providers encounter this population. Furthermore, this study sought to describe the health care settings most frequented by victims of human trafficking. This was an anonymous, retrospective study of survivors of U.S.-based human trafficking. One hundred and seventy-three participants who endured U.S.-based human trafficking were surveyed. The majority (68%, n=117) of participants were seen by a health care provider while being trafficked. Respondents most frequently reported visiting emergency/urgent care practitioners (56%), followed by primary care providers, dentists, and obstetricians/gynecologists (OB/GYNs). While health care providers are serving this patient population, they do not consistently identify them as victims of human trafficking.

Greenbaum, Jordan; Bodrick, Nia

Trafficking of children for labor and sexual exploitation violates basic human rights and constitutes a major global public health problem. Pediatricians and other health care professionals may encounter victims who present with infections, injuries, posttraumatic stress disorder, suicidality, or a variety of other physical or behavioral health conditions. Preventing child trafficking, recognizing victimization, and intervening appropriately require a public health approach that incorporates rigorous research on the risk factors, health impact, and effective treatment options for child exploitation as well as implementation and evaluation of primary prevention programs. Health care professionals need training to recognize possible signs of exploitation and to intervene appropriately. They need to adopt a multidisciplinary, outward-focused approach to service provision, working with nonmedical professionals in the community to assist victims. Pediatricians also need to advocate for legislation and policies that promote child rights and victim services as well as those that address the social determinants of health, which influence the vulnerability to human trafficking. This policy statement outlines major issues regarding public policy, medical education, research, and collaboration in the area of child labor and sex trafficking and provides recommendations for future work.

Human liver cell trafficking mutants: characterization and whole exome sequencing.

Directory of Open Access Journals (Sweden)

Fei Yuan

Full Text Available The HuH7 liver cell mutant Trf1 is defective in membrane trafficking and is complemented by the casein kinase 2α subunit CK2α''. Here we identify characteristic morphologies, trafficking and mutational changes in six additional HuH7 mutants Trf2-Trf7. Trf1 cells were previously shown to be severely defective in gap junction functions. Using a Lucifer yellow transfer assay, remarkable attenuation of gap junction communication was revealed in each of the mutants Trf2-Trf7. Electron microscopy and light microscopy of thiamine pyrophosphatase showed that several mutants exhibited fragmented Golgi apparatus cisternae compared to parental HuH7 cells. Intracellular trafficking was investigated using assays of transferrin endocytosis and recycling and VSV G secretion. Surface binding of transferrin was reduced in all six Trf2-Trf7 mutants, which generally correlated with the degree of reduced expression of the transferrin receptor at the cell surface. The mutants displayed the same transferrin influx rates as HuH7, and for efflux rate, only Trf6 differed, having a slower transferrin efflux rate than HuH7. The kinetics of VSV G transport along the exocytic pathway were altered in Trf2 and Trf5 mutants. Genetic changes unique to particular Trf mutants were identified by exome sequencing, and one was investigated in depth. The novel mutation Ile34Phe in the GTPase RAB22A was identified in Trf4. RNA interference knockdown of RAB22A or overexpression of RAB22AI34F in HuH7 cells caused phenotypic changes characteristic of the Trf4 mutant. In addition, the Ile34Phe mutation reduced both guanine nucleotide binding and hydrolysis activities of RAB22A. Thus, the RAB22A Ile34Phe mutation appears to contribute to the Trf4 mutant phenotype.

Risk Factors for Domestic Child Sex Trafficking in the United States.

Fedina, Lisa; Williamson, Celia; Perdue, Tasha

2016-07-01

Despite increased effort to respond to human trafficking at national and state levels, very little empirical research has been conducted on domestic child sex trafficking. This study retrospectively examines associations between multiple risk factors and domestic child sex trafficking (i.e., entry into the commercial sex industry under the age of 18) in a sample of individuals aged 16 and older currently involved in the commercial sex industry ( N = 273). Two primary research questions are addressed: (1) What set of risk factors, prior to entering the commercial sex industry, are associated with domestic child sex trafficking and (2) what group differences, if any, exist in risk factors between current or former domestic child sex-trafficking victims and non-trafficked adults engaged in the commercial sex industry? A cross-sectional survey was administered using Respondent-Driven Sampling (RDS) in five cities in one Midwestern state. Overall, 115 participants (48.3%) were identified as current or former domestic child sex-trafficking victims. Bivariate results suggest that childhood emotional and sexual abuse, rape, ever running away from home, having family members in sex work, and having friends who purchased sex were significantly associated with domestic child sex trafficking. Multivariate results indicate that domestic child sex trafficking victims were significantly more likely to have ever run away and to be a racial/ethnic minority than non-trafficked adults engaged in the commercial sex industry. Findings can inform state-level policies on human trafficking and assist child protection and juvenile justice agencies in developing prevention and intervention responses to commercial sexual exploitation.

Modeling for Determinants of Human Trafficking: An Empirical Analysis

2015-02-01

Full Text Available This study aims to identify robust push and pull factors of human trafficking. I test for the robustness of 70 push and 63 pull factors suggested in the literature. In doing so, I employ an extreme bound analysis, running more than two million regressions with all possible combinations of variables for up to 153 countries during the period of 1995–2010. My results show that crime prevalence robustly explains human trafficking both in destination and origin countries. Income level also has a robust impact, suggesting that the cause of human trafficking shares that of economic migration. Law enforcement matters more in origin countries than destination countries. Interestingly, a very low level of gender equality may have constraining effects on human trafficking outflow, possibly because gender discrimination limits female mobility that is necessary for the occurrence of human trafficking.

Preventing trafficking in women and children in Asia: issues and options.

Bennett, T

1999-09-01

This article discusses the issues and options in the prevention of trafficking of women and children in Asia. Studies revealed a higher prevalence of trafficking in Asian countries such as Nepal, India, Bangladesh, Philippines, Cambodia, and Thailand. This is due to a huge population, growing urbanization, and poverty. Several programs by the government and nongovernmental organizations have been developed to address the trafficking problem. In Nepal, the Maiti program was organized to help trafficking victims return to their home country, while occupational alternatives and awareness campaigns were organized for young women vulnerable to trafficking. In Thailand, greater penalties were imposed to customers as compared to the sellers so as to discourage the continuance and decrease the prevalence of trafficking. Other strategies have also been identified, such as prosecution of procurers, community awareness through campaigns, poverty alleviation, and gender equalization to address the trafficking problem.

Membrane trafficking pathways and their roles in plant-microbe interactions.

Inada, Noriko; Ueda, Takashi

2014-04-01

Membrane trafficking functions in the delivery of proteins that are newly synthesized in the endoplasmic reticulum (ER) to their final destinations, such as the plasma membrane (PM) and the vacuole, and in the internalization of extracellular components or PM-associated proteins for recycling or degradative regulation. These trafficking pathways play pivotal roles in the rapid responses to environmental stimuli such as challenges by microorganisms. In this review, we provide an overview of the current knowledge of plant membrane trafficking and its roles in plant-microbe interactions. Although there is little information regarding the mechanism of pathogenic modulation of plant membrane trafficking thus far, recent research has identified many membrane trafficking factors as possible targets of microbial modulation.

Human trafficking is a major global public health problem and represents a substantial human rights violation. Human trafficking has been receiving attention in both the lay media and professional literature. Human trafficking can include commercial sex, forced labor, child soldiers, and stealing of human organs. One form of human trafficking represents a significant American pediatric health problem: domestic minor sex trafficking (DMST). DMST is the commercial sexual abuse of children by selling, buying, or trading their sexual service. This continuing education article will define DMST and discuss it in terms of prevalence, risk factors, and practice implications for the pediatric nurse practitioner.

Compounds that correct F508del-CFTR trafficking can also correct other protein trafficking diseases: an in vitro study using cell lines

Directory of Open Access Journals (Sweden)

Sampson Heidi M

2013-01-01

Full Text Available Abstract Background Many genetic diseases are due to defects in protein trafficking where the mutant protein is recognized by the quality control systems, retained in the endoplasmic reticulum (ER, and degraded by the proteasome. In many cases, the mutant protein retains function if it can be trafficked to its proper cellular location. We have identified structurally diverse correctors that restore the trafficking and function of the most common mutation causing cystic fibrosis, F508del-CFTR. Most of these correctors do not act directly as ligands of CFTR, but indirectly on other pathways to promote folding and correction. We hypothesize that these proteostasis regulators may also correct other protein trafficking diseases. Methods To test our hypothesis, we used stable cell lines or transient transfection to express 2 well-studied trafficking disease mutations in each of 3 different proteins: the arginine-vasopressin receptor 2 (AVPR2, also known as V2R, the human ether-a-go-go-related gene (KCNH2, also known as hERG, and finally the sulfonylurea receptor 1 (ABCC8, also known as SUR1. We treated cells expressing these mutant proteins with 9 structurally diverse F508del-CFTR correctors that function through different cellular mechanisms and assessed whether correction occurred via immunoblotting and functional assays. Results were deemed significantly different from controls by a one-way ANOVA (p  Results Here we show that F508del-CFTR correctors RDR1, KM60 and KM57 also correct some mutant alleles of other protein trafficking diseases. We also show that one corrector, the cardiac glycoside ouabain, was found to alter the glycosylation of all mutant alleles tested. Conclusions Correctors of F508del-CFTR trafficking might have broader applications to other protein trafficking diseases.

Human trafficking and health: a conceptual model to inform policy, intervention and research.

Zimmerman, Cathy; Hossain, Mazeda; Watts, Charlotte

2011-07-01

Human trafficking is an international crime renowned for extreme forms of violence against women, men and children. Although trafficking-related violence has been well-documented, the health of trafficked persons has been a largely neglected topic. For people who are trafficked, health risks and consequences may begin before they are recruited into the trafficking process, continue throughout the period of exploitation and persist even after individuals are released. Policy-making, service provision and research often focus narrowly on criminal violations that occur during the period of exploitation, regularly overlooking the health implications of trafficking. Similarly, the public health sector has not yet incorporated human trafficking as a health concern. We present a conceptual model that highlights the migratory and exploitative nature of a multi-staged trafficking process, which includes: 'recruitment', travel-transit', 'exploitation' and 'integration' or 'reintegration', and for some trafficked persons, 'detention' and 're-trafficking' stages. Trafficked persons may suffer from physical, sexual and psychological harm, occupational hazards, legal restrictions and difficulties associated with being marginalised or stigmatised. Researchers and decision-makers will benefit from a theoretical approach that conceptualizes trafficking and health as a multi-staged process of cumulative harm. To address a health risk such as trafficking, which spans geographical boundaries and involves multiple sectors, including immigration and law enforcement, labour, social and health services, interventions must be coordinated between nations and across sectors to promote the protection and recovery of people who are trafficked.

Healthcare providers have the potential to play a crucial role in human trafficking prevention, identification, and intervention. However, trafficked patients are often unidentified due to lack of education and preparation available to healthcare professionals at all levels of training and practice. To increase victim identification in healthcare settings, providers need to be educated about the issue of trafficking and its clinical presentations in an interactive format that maximizes learning and ultimately patient-centered outcomes. In 2014, University of Louisville School of Medicine created a simulation-based medical education (SBME) curriculum to prepare students to recognize victims and intervene on their behalf. The authors share the factors that influenced the session's development and incorporation into an already full third year medical curriculum and outline the development process. The process included a needs assessment for the education intervention, development of objectives and corresponding assessment, implementation of the curriculum, and finally the next steps of the module as it develops further. Additional alternatives are provided for other medical educators seeking to implement similar modules at their home institution. It is our hope that the description of this process will help others to create similar interactive educational programs and ultimately help trafficking survivors receive the care they need.

Bloem, Christina; Morris, Rikki E; Chisolm-Straker, Makini

2017-01-01

Given the significant global burden of human trafficking, the ability of clinicians to identify and provide treatment for trafficked persons is critical. Particularly in conflict settings, health care facilities often serve as the first and sometimes only point of contact for trafficked persons. As such, medical practitioners have a unique opportunity and an ethical imperative to intervene, even in nonclinical roles. With proper training, medical practitioners can assist trafficked persons by documenting human trafficking cases, thereby placing pressure on key stakeholders to enforce legal protections, and by providing adequate services to those trafficked. © 2017 American Medical Association.

The Anatomy of Human Trafficking: Learning About the Blues: A Healthcare Provider's Guide.

Science.gov (United States)

Stevens, Meriam; Berishaj, Kelly

2016-01-01

Human trafficking is a major global public health concern. It is a grave crime that violates human rights. Contrary to healthcare providers' perceptions, victims of human trafficking come in contact with the healthcare system while being trafficked, with the emergency department being the most frequented setting for medical treatment. In this article, we explore the anatomy of human trafficking, including the scope of the problem, definitions, and types and elements of human trafficking. The roles of clinicians, particularly emergency department nurses and advanced practice nurses, in screening and identifying those at risk are examined. Clinical practice tools and guidelines that may be used by clinicians to guide the treatment of human trafficking victims are reviewed. Finally, current strategies and resources that address human trafficking are presented. For the purpose of this article, the terms "human trafficking" or "trafficking" will be used throughout.

Andrographolide regulates epidermal growth factor receptor and transferrin receptor trafficking in epidermoid carcinoma (A-431) cells

Science.gov (United States)

Tan, Y; Chiow, KH; Huang, D; Wong, SH

2010-01-01

Background and purpose: Andrographolide is the active component of Andrographis paniculata, a plant used in both Indian and Chinese traditional medicine, and it has been demonstrated to induce apoptosis in different cancer cell lines. However, not much is known about how it may affect the key receptors implicated in cancer. Knowledge of how andrographolide affects receptor trafficking will allow us to better understand new mechanisms by which andrographolide may cause death in cancer cells. Experimental approach: We utilized the well-characterized epidermal growth factor receptor (EGFR) and transferrin receptor (TfR) expressed in epidermoid carcinoma (A-431) cells as a model to study the effect of andrographolide on receptor trafficking. Receptor distribution, the total number of receptors and surface receptors were analysed by immunofluorescence, Western blot as well as flow-cytometry respectively. Key results: Andrographolide treatment inhibited cell growth, down-regulated EGFRs on the cell surface and affected the degradation of EGFRs and TfRs. The EGFR was internalized into the cell at an increased rate, and accumulated in a compartment that co-localizes with the lysosomal-associated membrane protein in the late endosomes. Conclusion and implications: This study sheds light on how andrographolide may affect receptor trafficking by inhibiting receptor movement from the late endosomes to lysosomes. The down-regulation of EGFR from the cell surface also indicates a new mechanism by which andrographolide may induce cancer cell death. PMID:20233216

National Human Trafficking Initiatives: Dimensions of Policy Diffusion1

Science.gov (United States)

Yoo, Eun-hye; Boyle, Elizabeth Heger

2014-01-01

The implementation of criminal law involves formal law enforcement, education and public outreach aimed at preventing criminal activity, and providing services for victims. Historically, quantitative research on global trends has tended to focus on a single policy dimension, potentially masking the unique factors that affect the diffusion of each policy dimension independently. Using an ordered-probit model to analyze new human trafficking policy data on national prosecution, prevention, and victim-protection efforts, we find that global ties and domestic interest groups matter more in areas where international law is less defined. While prosecution, officially mandated by the Trafficking Protocol, was relatively impervious to global ties and domestic interest groups, both trafficking prevention and victim protection were associated with these factors. Our findings also suggest that fear of repercussions is not a major driver of state actions to combat trafficking—neither ratification of the Trafficking Protocol nor levels of United States aid were associated with greater implementation of anti-trafficking measures.

Christina Bain

2017-06-01

Full Text Available There has been much discussed and written on the benefits of entrepreneurship education, as well as the importance of early access to this type of learning. But how can entrepreneurship education train and inspire the next generation of anti-trafficking leaders? How can entrepreneurship also be a driver for prevention and a source of economic stability for those at-risk and survivors of human trafficking? At present, there are entrepreneurs and entrepreneurs-in-training at multiple age levels coming from a variety of backgrounds, incomes, and circumstances who will develop groundbreaking strategies and solutions in the fight against trafficking. These current and future entrepreneurs can also provide fresh perspectives to those in government and business while building more effective tri-sector coalitions and partnerships that address human trafficking. This article explores how and why entrepreneurship can be a key vehicle for social change and innovations in combating human trafficking, along with providing a multi-ingredient recipe of prosperity for those most vulnerable.

Attitudes About Human Trafficking: Individual Differences Related to Belief and Victim Blame.

Science.gov (United States)

Cunningham, Katherine C; Cromer, Lisa DeMarni

2016-01-01

Human trafficking is believed to oppress millions of people worldwide. Despite increased media attention and public awareness campaigns in recent years, no empirical research has examined public attitudes about human trafficking. The present study examined gender, sexual trauma history, and attitudes about human trafficking as they related to belief of a sex-trafficking scenario and willingness to blame the victim for the situation. Undergraduate students (N = 409) at a large private university in the Northeastern United States completed measures in which they responded to a vignette portraying sex trafficking in the United States. Participants also reported their personal trauma history and completed a Human Trafficking Myths Scale. Results indicated that gender and human trafficking myth acceptance, but not sexual trauma history, were significantly related to participants' belief of the sex-trafficking scenario and their perception of the victim's responsibility. Potential implications and directions for future research are discussed. © The Author(s) 2014.

The Fight against the Least Visible Form of Human Trafficking: Trafficking for Child Labour Exploitation

Directory of Open Access Journals (Sweden)

Luz María Puente Aba

2018-03-01

Full Text Available Child trafficking for the purpose of labour exploitation is a difficult phenomenon to detect. It is also not readily definable considering that this specific form of trafficking is closely linked with the phenomenon of forced child labour, and even with the broader occurrence of child labour. A lack of globally reliable data and the convergence of different concepts related to child trafficking for labour exploitation pose significant challenges when trying to regulate the circumstances concerning child work and the criminalisation of trafficking for labour exploitation. This article offers a clear overview of the available data related to all the phenomena, and aims to clarify all the situations involved, defining child work, child labour, forced child labour and child trafficking for the purposes of labour exploitation. Furthermore, this article discusses the possible loopholes and critical issues that could hinder global approaches to resolving these issues. La trata infantil con fines de explotación laboral es un fenómeno difícil de detectar, y tampoco es sencillo definirlo si se tiene en cuenta que esta forma específica de trata está estrechamente relacionada con el fenómeno del trabajo forzado infantil e, incluso, con el fenómeno más general de trabajo infantil. Todo ello supone un desafío a la hora de regular las circunstancias que definen el trabajo realizado por niños y la criminalización de la trata para la explotación laboral. Este artículo ofrece un repaso de los datos disponibles en esta materia y procura aclarar las situaciones que se pueden plantear, así como definir trabajo realizado por niños, trabajo infantil, trabajo infantil forzado y trata infantil con fines de explotación laboral. Por último, profundiza en las posibles deficiencias y en los aspectos críticos que podrían obstaculizar un acercamiento global a esta problemática.

Public Discourse on Human Trafficking in International Issue Arenas

Niina Meriläinen

2015-01-01

Full Text Available The purpose of this study is to better understand how the complex problem of human trafficking is addressed in international debates. How the discussion about human trafficking develops and how it is debated ultimately influences how the decision-making process unfolds. In order to understand the formation of public policy and laws, therefore, it is important to study the debate that occurs prior to decision making. This analysis focuses on the narratives used by major, well-established human rights and political actors that argue for necessary actions to be undertaken—such as the formation of new policies and laws in the European Union—as an attempt to protect citizens of the EU and other regions in the world from becoming victims of trafficking networks. Our research examines how the topic of human trafficking is framed and how this framework is intertwined in the debate with other social problems. We focus on how human trafficking is discussed by two well-established human rights Non-Governmental Organizations (NGOs, Amnesty International (Amnesty and Human Rights Watch (HRW, in addition to the European Parliament (EP. The research questions for this study include: (1 In what context is human trafficking discussed by the three actors? (2 How do these actors frame the definition of human trafficking in their presentations? To answer these questions, we have conducted a systematic content analysis of documents that include official statements and research reports of the NGOs, as well as resolutions and recommendations of the EP. Altogether, 240 documents were analyzed in detail. These findings indicate that the two human rights organizations, Amnesty and Human Rights Watch, along with the European Parliament, all address human trafficking as an important social problem, albeit to varying degrees. Each actor has a different method of correlating human trafficking with many other social problems, thereby emphasizing different causes and

2017-01-01

Human trafficking, including both sex and labor trafficking, has profound consequences for the safety, health, and well-being of victims and survivors. Efforts to address human trafficking through prevention, protection, and prosecution are growing but remain insufficient. Mandatory reporting has the potential to bring victims and survivors to the attention of social service and law enforcement agencies but may discourage trafficked persons from seeking help, thereby limiting the ability of health care professionals to establish trust and provide needed care. States' experience in implementing child abuse laws can be useful in assessing the potential risks and benefits of mandatory reporting of human trafficking. © 2017 American Medical Association.

Rab4GTPase modulates CFTR function by impairing channel expression at plasma membrane

International Nuclear Information System (INIS)

Saxena, Sunil K.; Kaur, Simarna; George, Constantine

2006-01-01

Cystic fibrosis (CF), an autosomal recessive disorder, is caused by the disruption of biosynthesis or the function of a membrane cAMP-activated chloride channel, CFTR. CFTR regulatory mechanisms include recruitment of channel proteins to the cell surface from intracellular pools and by protein-protein interactions. Rab proteins are small GTPases involved in regulated trafficking controlling vesicle docking and fusion. Rab4 controls recycling events from endosome to the plasma membrane, fusion, and degradation. The colorectal cell line HT-29 natively expresses CFTR and responds to cAMP stimulation with an increase in CFTR-mediated currents. Rab4 over-expression in HT-29 cells inhibits both basal and cAMP-stimulated CFTR-mediated currents. GTPase-deficient Rab4Q67L and GDP locked Rab4S22N both inhibit channel activity, which appears characteristically different. Active status of Rab4 was confirmed by GTP overlay assay, while its expression was verified by Western blotting. The pull-down and immunoprecipitation experiments suggest that Rab4 physically interacts with CFTR through protein-protein interaction. Biotinylation with cell impermeant NHS-Sulfo-SS-Biotin implies that Rab4 impairs CFTR expression at cell surface. The enhanced cytosolic CFTR indicates that Rab4 expression restrains CFTR appearance at the cell membrane. The study suggests that Rab4 regulates the channel through multiple mechanisms that include protein-protein interaction, GTP/GDP exchange, and channel protein trafficking. We propose that Rab4 is a dynamic molecule with a significant role in CFTR function

Bacterial pathogen manipulation of host membrane trafficking.

Asrat, Seblewongel; de Jesús, Dennise A; Hempstead, Andrew D; Ramabhadran, Vinay; Isberg, Ralph R

2014-01-01

Pathogens use a vast number of strategies to alter host membrane dynamics. Targeting the host membrane machinery is important for the survival and pathogenesis of several extracellular, vacuolar, and cytosolic bacteria. Membrane manipulation promotes bacterial replication while suppressing host responses, allowing the bacterium to thrive in a hostile environment. This review provides a comprehensive summary of various strategies used by both extracellular and intracellular bacteria to hijack host membrane trafficking machinery. We start with mechanisms used by bacteria to alter the plasma membrane, delve into the hijacking of various vesicle trafficking pathways, and conclude by summarizing bacterial adaptation to host immune responses. Understanding bacterial manipulation of host membrane trafficking provides insights into bacterial pathogenesis and uncovers the molecular mechanisms behind various processes within a eukaryotic cell.

Shaping the Victim: Borders, security, and human trafficking in Albania

Directory of Open Access Journals (Sweden)

James Campbell

2013-09-01

Full Text Available Borders are productive sites where knowledge is gathered and migrant populations are formed. The knowledge gathered from victims of trafficking reinforces a victim narrative that represents a perceived threat to society by highlighting violence, criminality, coercion, and naivety. Using Albania as a case in point, the article looks at trafficked people and the narratives of victimhood that surround them. In the case of trafficked people, the border projected out towards other states produces a discursively defined victim of trafficking. When projected back within the national territory, the border essentially produces a criminalised sex worker. To argue this point, the article discusses the role victims of trafficking play in the EU and looks at how international norms espoused by the OSCE and IOM have prepped the Albanian border for EU ascension and created the means for governable populations within Albania.

Human Trafficking: Fighting the Illicit Economy with the Legitimate Economy

Directory of Open Access Journals (Sweden)

Louise Shelley

2015-02-01

Full Text Available Since the beginning of research on human trafficking, there has been attention paid to the challenges surrounding the illicit economy. In creating new strategies and initiatives on combatting human trafficking, there needs to be more discussion surrounding the legitimate economy and how the business sector can make an impact in the fight against trafficking. Currently, there is a growing movement of businesses that are looking to address human trafficking through training, education, and leadership initiatives; codes of conduct; supply chain management; and financial analysis. This paper will examine the latest in these strategies and approaches by businesses in the global war against human trafficking, in addition to a discussion of a new initiative engaging the private sector co-led by Dr. Louise Shelley and Christina Bain through the World Economic Forum’s Global Agenda Council Network.

Constraints to a Robust Evidence Base for Anti-Trafficking Interventions

Directory of Open Access Journals (Sweden)

Benjamin Harkins

2017-04-01

Full Text Available Over fifteen years after the UN Trafficking Protocol was adopted, the evidence available to determine how much progress has been made in combatting human trafficking remains very limited. This paper provides a practitioner’s perspective on some of the main reasons for the continuing lack of meaningful results documented in the context of anti-trafficking projects. A key finding is that limitations in the practice of monitoring and evaluation (M&E pose the greatest constraint rather than the clandestine nature of trafficking in persons. There are currently few incentives to be rigorous in pursuing evidence, especially of the contribution made to long-term reductions in human trafficking. Bean counting the direct outputs of activities rather than assessing the outcomes that are intended to flow from them remains the core approach to M&E in the sector. Because the collection and analysis of data has not been prioritised, anti-trafficking initiatives without a strong empirical basis are reflexively continued for years–particularly notable in some of the untested assumptions about the central importance of an effective criminal justice response. Increased commitment by donors and practitioners to raise their standards of evidence for anti-trafficking projects is necessary to move beyond basic accountability and start leveraging learning, including greater willingness to document in rich detail where interventions have failed to produce their intended outcomes.

Human trafficking: Commercial sexual exploitation and forced domestic labour in African literature

Directory of Open Access Journals (Sweden)

Urama Evelyn Nwachukwu

2017-05-01

Full Text Available Just like social occurrences such as human sacrifice and slavery enhanced retardation of progress in Africa in the past, trafficking is another social occurrence addressed in contemporary African literature that impedes progress and tarnishes the image of the victims. Human trafficking is rampant in Africans and some part of the world in this 21st century. This paper examines how Akachi Adimora-Ezeigbo’s Trafficked (2008 and Chika Unigwe’s On Black Sisters′ Street (2009 highlight social occurrences and how they contribute to the spread of girl trafficking in Africa. It also explores how both men and women are partners in trafficking, forming trafficking networks that lure girls from Nigeria to Europe and make huge profits from their misery. These pimps use ‘juju magic’ and rituals as a threat to exert complete control over the girls and also to ensure their compliance. The trafficked girls share their life experiences by telling their tales of woes exposing the shame that accompanies the sex trade and the stigmatization they suffer in the society. Their experiences are presented by the authors to highlight the trafficked girls′ pains, misery and struggle for freedom in order to appeal to everybody in the society to fight against human trafficking. The paper also examines how these exploited and depressed trafficked girls that have lost their self-esteem can still live fulfilled lives if government agencies and nongovernmental organizations come to their rescue.

A model for assessing the risk of human trafficking on a local level

Science.gov (United States)

Colegrove, Amanda

Human trafficking is a human rights violation that is difficult to quantify. Models for estimating the number of victims of trafficking presented by previous researchers depend on inconsistent, poor quality data. As an intermediate step to help current efforts by nonprofits to combat human trafficking, this project presents a model that is not dependent on quantitative data specific to human trafficking, but rather profiles the risk of human trafficking at the local level through causative factors. Businesses, indicated by the literature, were weighted based on the presence of characteristics that increase the likelihood of trafficking in persons. The mean risk was calculated by census tract to reveal the multiplicity of risk levels in both rural and urban settings. Results indicate that labor trafficking may be a more diffuse problem in Missouri than sex trafficking. Additionally, spatial patterns of risk remained largely the same regardless of adjustments made to the model.

Editorial: How is the money to combat human trafficking spent?

Directory of Open Access Journals (Sweden)

Mike Dottridge

2014-09-01

This edition of the Anti-Trafficking Review explores what happens to the money that is allocated by governments and private donors to stop human trafficking and to assist people who have been trafficked. It has been an honour to play the role of guest editor, though it has not been easy to steer a route between amazement (at the sums apparently involved, concern (at the lack of real insight into how money is allocated and spent and cynicism (at what appear to be rather modest achievements. It was challenging for potential authors to choose a method of analysing anti-trafficking spending. Should they simply describe what money is available and the drawbacks of the ways which donors make it available to organisations to use? Some authors take this descriptive approach. Should articles be about the efficiency and effectiveness of aid flows in general, in which case the shortcomings in anti-trafficking funding may mirror the generic flaws in aid flows? Only one author (Ucnikova has tackled this. Or, should studies focus on the way the purse strings are controlled by a small number of donors who appear poorly informed about the needs of trafficked persons or the factors that cause them to be trafficked? Several of the articles touch on this (e.g. those of Hoff and Nwogu. Early on, it became apparent to the editorial team that people working for large organisations with anti-trafficking programmes were wary of contributing articles on this topic. In this sense, although the Anti-Trafficking Review aims to promote public debate, we have not yet found the best way of opening up a debate about funding, for practitioners evidently fear that writing about their own sources of funding could result in the tap being turned off! So, it is mainly the Debate section that tackles the question of funding strategies. Even these contributions do not make assessments of the various actors involved (donors and the organisations they fund in as full and frank a way as is needed. The

Jacobsen syndrome (JBS) is a rare congenital disorder caused by a terminal deletion of the long arm of chromosome 11. A subset of patients exhibit social behavioural problems that meet the diagnostic criteria for autism spectrum disorder (ASD); however, the underlying molecular pathogenesis remains poorly understood. PX-RICS is located in the chromosomal region commonly deleted in JBS patients with autistic-like behaviour. Here we report that PX-RICS-deficient mice exhibit ASD-like social behaviours and ASD-related comorbidities. PX-RICS-deficient neurons show reduced surface γ-aminobutyric acid type A receptor (GABAAR) levels and impaired GABAAR-mediated synaptic transmission. PX-RICS, GABARAP and 14-3-3ζ/θ form an adaptor complex that interconnects GABAAR and dynein/dynactin, thereby facilitating GABAAR surface expression. ASD-like behavioural abnormalities in PX-RICS-deficient mice are ameliorated by enhancing inhibitory synaptic transmission with a GABAAR agonist. Our findings demonstrate a critical role of PX-RICS in cognition and suggest a causal link between PX-RICS deletion and ASD-like behaviour in JBS patients.

Endocytosis and Endosomal Trafficking in Plants.

Science.gov (United States)

Paez Valencia, Julio; Goodman, Kaija; Otegui, Marisa S

2016-04-29

Endocytosis and endosomal trafficking are essential processes in cells that control the dynamics and turnover of plasma membrane proteins, such as receptors, transporters, and cell wall biosynthetic enzymes. Plasma membrane proteins (cargo) are internalized by endocytosis through clathrin-dependent or clathrin-independent mechanism and delivered to early endosomes. From the endosomes, cargo proteins are recycled back to the plasma membrane via different pathways, which rely on small GTPases and the retromer complex. Proteins that are targeted for degradation through ubiquitination are sorted into endosomal vesicles by the ESCRT (endosomal sorting complex required for transport) machinery for degradation in the vacuole. Endocytic and endosomal trafficking regulates many cellular, developmental, and physiological processes, including cellular polarization, hormone transport, metal ion homeostasis, cytokinesis, pathogen responses, and development. In this review, we discuss the mechanisms that mediate the recognition and sorting of endocytic and endosomal cargos, the vesiculation processes that mediate their trafficking, and their connection to cellular and physiological responses in plants.

Liberal coercion? Prostitution, human trafficking and policy

OpenAIRE

Cho, Seo-young

2013-01-01

Liberal prostitution policy aims at improving labour conditions for prostitutes and protecting victims of forced prostitution. Its policy orientation predicts that the policy choice of liberalizing prostitution is positively associated with better protection policy for trafficking victims and enhanced anti-trafficking measures. In this paper, I investigate empirically whether the legalization of prostitution improves protection policy for victims, as it is presumed. The results of my analysis...

Antibody–drug conjugate (ADC) is a milestone in targeted cancer therapy that comprises of monoclonal antibodies chemically linked to cytotoxic drugs. Internalization of ADC takes place via clathrin-mediated endocytosis, caveolae-mediated endocytosis, and pinocytosis. Conjugation strategies, endocytosis and intracellular trafficking optimization, linkers, and drugs chemistry present a great challenge for researchers to eradicate tumor cells successfully. This inventiveness of endocytosis and intracellular trafficking has given considerable momentum recently to develop specific antibodies and ADCs to treat cancer cells. It is significantly advantageous to emphasize the endocytosis and intracellular trafficking pathways efficiently and to design potent engineered conjugates and biological entities to boost efficient therapies enormously for cancer treatment. Current studies illustrate endocytosis and intracellular trafficking of ADC, protein, and linker strategies in unloading and also concisely evaluate practically applicable ADCs. PMID:28814834

We present here evidence of in vivo epithelial endocytosis and trafficking of non-lipid-modified Sonic hedgehog (ShhN) when infused into rat efferent ducts via microinjection. Initially, exogenous ShhN is detected in endocytic vesicles and early endosomes located near the apical plasma membrane of non-ciliated cells. Within 30-60 min following infusion, ShhN can be detected in lysosomes and at basolateral regions of non-ciliated cells. Basolaterally, ShhN was observed along the extracellular surfaces of interdigitated plasma membranes of adjacent cells and in the extracellular compartment underlying the efferent duct epithelium. Uptake and subcellular trafficking of infused ShhN by non-ciliated cells could be blocked by either anti-megalin IgG or the megalin antagonist, RAP. Ciliated cells, which do not express megalin, displayed little if any apical internalization of ShhN even though they were found to express Patched-1. However, ShhN was found in coated pits of lateral plasma membranes of ciliated cells as well as in underlying endocytic vesicles. We conclude that megalin-mediated endocytosis of ShhN can occur in megalin-expressing epithelia in vivo, and that the internalized ShhN can be targeted to the lysosome or transcytosed in the plane of the epithelium or across the epithelium. These findings highlight the multiple mechanisms by which megalin may influence Shh morphogen gradients in vivo.

Efforts of Turkey in combating with illicit trafficking of nuclear materials and other radioactive sources

Full text: Illicit trafficking of nuclear materials and other radioactive sources creates both non-proliferation problems and also is a radiation hazard risk for the law enforcement officers, public and the environment. Since the illicit trafficking and trading of nuclear materials and other radioactive sources has been increasing over the past years, it is very important to take immediate measures for preventing these activities. Turkey, as a country having a unique position at the crossing points of the two major routes - one connecting the Black Sea to the Mediterranean and the other connecting Europe to Asia and the Middle East - is situated on the routes of illicit trafficking. Thus, Turkey attaches great importance to combating illicit trafficking and strongly supports all efforts in this field. After the IAEA resolution GC(XXXVIII)RES/15 requesting Member States to 'take all necessary measures to prevent illicit trafficking in nuclear materials' had been adopted, Turkey gave full support to the IAEA Programme on Combating Illicit Nuclear and other Radioactive Materials and also took some measures to combat such trading. Regulatory activities regarding nuclear and radiological safety, including safeguards and physical protection in Turkey, are under the responsibility of the Turkish Atomic Energy Authority (TAEA). The TAEA ensures that the licensed activities do not cause any unreasonable risk to the public and to environmental safety and that they do not impair the common defense and security interest of Turkey. TAEA was established by the Act No.2690 of 9th July 1982 and replaced the Turkish Atomic Energy Commission created by the Act No.6821 in 1956. The Act No.2690 Authorizes the TAEA to carry out the activities connected with the fulfillment of Turkey's obligations arising from international agreements in the field of safeguards and physical protection. This paper covers the efforts and coordination role of TAEA's planned activities and the measures

P-glycoprotein trafficking as a therapeutic target to optimize CNS drug delivery.

Science.gov (United States)

Davis, Thomas P; Sanchez-Covarubias, Lucy; Tome, Margaret E

2014-01-01

The primary function of the blood-brain barrier (BBB)/neurovascular unit is to protect the central nervous system (CNS) from potentially harmful xenobiotic substances and maintain CNS homeostasis. Restricted access to the CNS is maintained via a combination of tight junction proteins as well as a variety of efflux and influx transporters that limits the transcellular and paracellular movement of solutes. Of the transporters identified at the BBB, P-glycoprotein (P-gp) has emerged as the transporter that is the greatest obstacle to effective CNS drug delivery. In this chapter, we provide data to support intracellular protein trafficking of P-gp within cerebral capillary microvessels as a potential target for improved drug delivery. We show that pain-induced changes in P-gp trafficking are associated with changes in P-gp's association with caveolin-1, a key scaffolding/trafficking protein that colocalizes with P-gp at the luminal membrane of brain microvessels. Changes in colocalization with the phosphorylated and nonphosphorylated forms of caveolin-1, by pain, are accompanied by dynamic changes in the distribution, relocalization, and activation of P-gp "pools" between microvascular endothelial cell subcellular compartments. Since redox-sensitive processes may be involved in signaling disassembly of higher-order structures of P-gp, we feel that manipulating redox signaling, via specific protein targeting at the BBB, may protect disulfide bond integrity of P-gp reservoirs and control trafficking to the membrane surface, providing improved CNS drug delivery. The advantage of therapeutic drug "relocalization" of a protein is that the physiological impact can be modified, temporarily or long term, despite pathology-induced changes in gene transcription. © 2014 Elsevier Inc.

αPIX Is a Trafficking Regulator that Balances Recycling and Degradation of the Epidermal Growth Factor Receptor.

Directory of Open Access Journals (Sweden)

Fanny Kortüm

Full Text Available Endosomal sorting is an essential control mechanism for signaling through the epidermal growth factor receptor (EGFR. We report here that the guanine nucleotide exchange factor αPIX, which modulates the activity of Rho-GTPases, is a potent bimodal regulator of EGFR trafficking. αPIX interacts with the E3 ubiquitin ligase c-Cbl, an enzyme that attaches ubiquitin to EGFR, thereby labelling this tyrosine kinase receptor for lysosomal degradation. We show that EGF stimulation induces αPIX::c-Cbl complex formation. Simultaneously, αPIX and c-Cbl protein levels decrease, which depends on both αPIX binding to c-Cbl and c-Cbl ubiquitin ligase activity. Through interaction αPIX sequesters c-Cbl from EGFR and this results in reduced EGFR ubiquitination and decreased EGFR degradation upon EGF treatment. However, quantitatively more decisive for cellular EGFR distribution than impaired EGFR degradation is a strong stimulating effect of αPIX on EGFR recycling to the cell surface. This function depends on the GIT binding domain of αPIX but not on interaction with c-Cbl or αPIX exchange activity. In summary, our data demonstrate a previously unappreciated function of αPIX as a strong promoter of EGFR recycling. We suggest that the novel recycling regulator αPIX and the degradation factor c-Cbl closely cooperate in the regulation of EGFR trafficking: uncomplexed αPIX and c-Cbl mediate a positive and a negative feedback on EGFR signaling, respectively; αPIX::c-Cbl complex formation, however, results in mutual inhibition, which may reflect a stable condition in the homeostasis of EGF-induced signal flow.

Queering the Support for Trafficked Persons: LGBTQ Communities and Human Trafficking in the Heartland

Corinne Schwarz

2015-02-01

Full Text Available Human trafficking justice centers on the “Three Ps” model of prevention, protection, and prosecution. While protection and prosecution efforts have been moderately successful, prevention remains elusive, as “upstream” structural fac-tors—class, gender, and sexuality inequalities—remain difficult to target. Individuals who are affected by these factors are not fully served within linear service frameworks. Based on a 12-month study in Kansas City, we find that service providers recognize the limitations of a “one-size-fits all” approach. Using a public health model, our research team con-ducted a public health surveillance, explored risk and protective factors, and facilitated organizational self-assessments of services. Our findings support a prevention approach that supports a survivor-centered model, which creates new, non-linear or queered avenues of agency and community for trafficking survivors. This model allows survivors to make use of services in moments of vulnerability and opt out of others in moments of resilience. Given the systematic cuts in funding that have affected service providers, this research contends that prevention is cheaper, more effective, and more ethical than relying on prosecutions to curb trafficking. Developing a model that fosters survivor empowerment is a key step toward individual justice and survivor resilience for vulnerable and marginalized populations.

The Role of Rab Proteins in Neuronal Cells and in the Trafficking of Neurotrophin Receptors

Directory of Open Access Journals (Sweden)

Cecilia Bucci

2014-10-01

Full Text Available Neurotrophins are a family of proteins that are important for neuronal development, neuronal survival and neuronal functions. Neurotrophins exert their role by binding to their receptors, the Trk family of receptor tyrosine kinases (TrkA, TrkB, and TrkC and p75NTR, a member of the tumor necrosis factor (TNF receptor superfamily. Binding of neurotrophins to receptors triggers a complex series of signal transduction events, which are able to induce neuronal differentiation but are also responsible for neuronal maintenance and neuronal functions. Rab proteins are small GTPases localized to the cytosolic surface of specific intracellular compartments and are involved in controlling vesicular transport. Rab proteins, acting as master regulators of the membrane trafficking network, play a central role in both trafficking and signaling pathways of neurotrophin receptors. Axonal transport represents the Achilles' heel of neurons, due to the long-range distance that molecules, organelles and, in particular, neurotrophin-receptor complexes have to cover. Indeed, alterations of axonal transport and, specifically, of axonal trafficking of neurotrophin receptors are responsible for several human neurodegenerative diseases, such as Huntington’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis and some forms of Charcot-Marie-Tooth disease. In this review, we will discuss the link between Rab proteins and neurotrophin receptor trafficking and their influence on downstream signaling pathways.

Poly-drug trafficking: Estimating the scale, trends and harms at the Australian border.

Hughes, Caitlin Elizabeth; Chalmers, Jenny; Bright, David Anthony; McFadden, Michael

2016-05-01

International drug law enforcement agencies have identified an apparent rise in high level drug traffickers choosing to deal in multiple different drugs. It is hypothesised that this may be a "deliberate modus operandi" and that the formation of "portfolios of trades" may make such traffickers more profitable, harmful and resilient to changes in drug supply and policing. In this paper we provide the first exploration of the extent, nature and harms of poly-drug trafficking at Australian borders. Two different methods were used. First, we used Australian Federal Police (AFP) data on all commercial level seizures at the Australian border from 1999 to 2012 to identify the proportion of seizures that were poly-drug and trends over time. Second, we used unit-record data on a sub-set of 20 drug trafficking cases and linked-cases (defined as the original drug trafficking case and all other criminal cases that were connected via common offenders and/or suspects) to compare the profiles of poly-drug and mono-drug traffickers, including: the total weight and type of drug seized, the value of assets seized, and the level of involvement in other crime (such as money laundering and corruption). Between 5% and 35% of commercial importations at the Australian border involved poly-drug trafficking. Poly-drug trafficking occurred in almost every year of analysis (1999-2012), but it increased only slightly over time. Compared to mono-drug traffickers poly-drug traffickers were characterised by: larger quantities of drugs seized, larger networks, longer criminal histories and more involvement in other types of serious crime. Some fears about poly-drug traffickers may have been overstated particularly about the inherent escalation of this form of trafficking. Nevertheless, this suggests poly-drug traffickers are likely to pose added risks to governments and law enforcement than mono-drug traffickers. They may necessitate different types of policy responses. Copyright © 2016 Elsevier

Regulation of AMPA Receptor Trafficking by Protein Ubiquitination

Directory of Open Access Journals (Sweden)

Jocelyn Widagdo

2017-10-01

Full Text Available The molecular mechanisms underlying plastic changes in the strength and connectivity of excitatory synapses have been studied extensively for the past few decades and remain the most attractive cellular models of learning and memory. One of the major mechanisms that regulate synaptic plasticity is the dynamic adjustment of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA-type glutamate receptor content on the neuronal plasma membrane. The expression of surface AMPA receptors (AMPARs is controlled by the delicate balance between the biosynthesis, dendritic transport, exocytosis, endocytosis, recycling and degradation of the receptors. These processes are dynamically regulated by AMPAR interacting proteins as well as by various post-translational modifications that occur on their cytoplasmic domains. In the last few years, protein ubiquitination has emerged as a major regulator of AMPAR intracellular trafficking. Dysregulation of AMPAR ubiquitination has also been implicated in the pathophysiology of Alzheimer’s disease. Here we review recent advances in the field and provide insights into the role of protein ubiquitination in regulating AMPAR membrane trafficking and function. We also discuss how aberrant ubiquitination of AMPARs contributes to the pathogenesis of various neurological disorders, including Alzheimer’s disease, chronic stress and epilepsy.

IRREGULAR MIGRATION FLOWS AND HUMAN TRAFFICKING IN THE WESTERN BALKAN COUNTRIES: CHALLENGES OF THE CONVERGENCE OF COUNTER-TRAFFICKING RESPONSE

Directory of Open Access Journals (Sweden)

Merita H. Mece

2016-05-01

Full Text Available Irregular migration on the Western Balkan route has marked an unprecedented number during the last five years. Evidence indicates that both, non-European nationals and Western Balkan citizens have been involved in this complex migratory flow being exposed to various risks of human trafficking. But Western Balkan countries are source, transit and destination countries of human trafficking while their states are not well organized to implement a comprehensive and well-coordinated regional response to combat it. This paper aims at examining challenges faced by the Western Balkan countries to converge anti-trafficking response while facing increased irregular migratory waves. Using secondary data it illustrates various disparities and differences among them concluding that a well-coordinated, multi-faceted and integrated regional response is needed to combat this humanitarian problem.

Psychological Coercion in Human Trafficking: An Application of Biderman's Framework.

Baldwin, Susie B; Fehrenbacher, Anne E; Eisenman, David P

2015-09-01

This study examined coercive conditions experienced by trafficked persons in the context of Biderman's theory of coercion. We conducted semi-structured interviews with 12 adult women trafficked into Los Angeles County, from 10 countries, for domestic work and/or sex work. Participants described health problems they experienced in relation to their trafficking experience and their perceptions of conditions that caused health problems. Utilizing a framework analysis approach, we analyzed themes using Biderman's framework. Participants reported experiencing the range of nonphysical coercive tactics outlined by Biderman, including isolation, monopolization of perception, induced debility or exhaustion, threats, occasional indulgences, demonstration of omnipotence, degradation, and enforcement of trivial demands. Our analysis demonstrates how these coercion tactics reinforced the submission of trafficked persons to their traffickers even in the absence of physical force or restraints. Such psychological abuse creates extreme stress that can lead to acute and chronic, physical and mental health problems. © The Author(s) 2014.

Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

Socio-Economic Inequality, Human Trafficking, and the Global Slave Trade

Directory of Open Access Journals (Sweden)

John R. Barner

2014-04-01

Full Text Available The purpose of this paper is to discuss human trafficking within the broader framework of socio-economic inequality. The presence of socio-economic inequality in the world creates a system where those in power very easily dominate and take advantage of those people without power. One of the most serious contemporary effects of inequalities between and within nations is the phenomenon of global sex trade or human trafficking for the purposes of sex. Deriving from unequal power relations, human trafficking is a serious global crime that involves the exploitation of many, but mostly females and children. This paper provides an extensive discussion of inequality and its links with human trafficking as contemporary slavery. In conclusion, the paper provides a list of selected intra-national and multi-national service organizations that are adopting strategies for combating trafficking through the reduction of social and economic inequality. Implications for social welfare advocates and international collaborative efforts are highlighted.

Dual pulse-chase microscopy reveals early divergence in the biosynthetic trafficking of the Na,K-ATPase and E-cadherin

Farr, Glen A.; Hull, Michael; Stoops, Emily H.; Bateson, Rosalie; Caplan, Michael J.

2015-01-01

Recent evidence indicates that newly synthesized membrane proteins that share the same distributions in the plasma membranes of polarized epithelial cells can pursue a variety of distinct trafficking routes as they travel from the Golgi complex to their common destination at the cell surface. In most polarized epithelial cells, both the Na,K-ATPase and E-cadherin are localized to the basolateral domains of the plasma membrane. To examine the itineraries pursued by newly synthesized Na,K-ATPase and E-cadherin in polarized MDCK epithelial cells, we used the SNAP and CLIP labeling systems to fluorescently tag temporally defined cohorts of these proteins and observe their behaviors simultaneously as they traverse the secretory pathway. These experiments reveal that E-cadherin is delivered to the cell surface substantially faster than is the Na,K-ATPase. Furthermore, the surface delivery of newly synthesized E-cadherin to the plasma membrane was not prevented by the 19°C temperature block that inhibits the trafficking of most proteins, including the Na,K-ATPase, out of the trans-Golgi network. Consistent with these distinct behaviors, populations of newly synthesized E-cadherin and Na,K-ATPase become separated from one another within the trans-Golgi network, suggesting that they are sorted into different carrier vesicles that mediate their post-Golgi trafficking.

Human trafficking is a form of modern-day slavery that is rapidly expanding in the United States and throughout the world. It is a crime under both the United States and international law. The child and adult victims of human trafficking are denied their basic human rights and subjected to unspeakable physical and emotional harm. Traffickers exert complete control over their victims and are proficient at hiding their condition from authorities. Healthcare practitioners may be the only professionals who come into contact with victims if they present for medical care. This article will describe human trafficking and its potential victims, as well as guide medical management and access to services that will ensure their safety and restore their freedom.

2018-06-01

Human trafficking is a serious and prevalent human rights violation that closely intersects with mental health. Limited empirical attention has been paid to the presentations and identification of trafficking victims in psychiatric settings. The primary goal of this paper is to describe the varied presentations of trafficking victims on an urban inpatient psychiatric unit. A literature review was conducted to identify relevant empirical articles to inform our examination of cases. Adult inpatient cases meeting criteria for known or possible human trafficking were systematically identified and illustrative cases were described. Six cases were identified including one male and five females. Two had been labor trafficked and four were suspected or confirmed to have been sex trafficked. The cases demonstrated a tremendous diversity of demographic and psychiatric identifying factors. These cases indicate the importance of routinely screening for trafficking victims in inpatient psychiatry settings. Identification of cases is a requisite step in providing informed and evidence-based treatments and enabling the secondary prevention of re-exploitation. Additional research is warranted given the limited current empirical research on this topic area.

Webster, Daniel W; Vernick, Jon S; Bulzacchelli, Maria T

2009-07-01

Criminals illegally obtaining firearms represent a great risk to many urban residents. This cross-sectional study of 54 US cities uses data on state laws governing gun sales, a survey of law enforcement agencies' practices to promote compliance with gun sales laws, and crime gun trace data to examine associations between these policies and practices with gun trafficking indicators. Higher levels of local gun ownership were linked with greater intrastate gun trafficking. Regression models estimate that comprehensive regulation and oversight of gun dealers and state regulation of private sales of handguns were each associated with significantly lower levels of intrastate gun trafficking. Discretionary permit-to-purchase licensing laws' negative association with intrastate trafficking disappeared when local gun ownership is controlled. The effects of these relatively restrictive gun purchase laws on trafficking may be mediated by the laws' lowering of gun ownership. Relatively low prevalence of gun ownership may also be a prerequisite for passage of discretionary purchase. We observed no effect on intrastate trafficking of laws limiting handgun sales to a maximum of one per person per month.

Public Perceptions of Human Trafficking in Moldova

Directory of Open Access Journals (Sweden)

Jill Robinson

2011-11-01

Full Text Available Human trafficking is a widely studied phenomenon. Comparing public perceptions of trafficking to institutional (i.e. the academy, governmental and non-governmental organizations perceptions gives a richer understanding of the problem. The data for this study were collected in and around Chisinau, Moldova in the summer of 2004. Public discourse provides a more intimate "portraiture" of the issue, but the public also demonstrated a complex level of understanding of this social problem in this study. Its view is juxtaposed against an institutional view of human trafficking as explored through a literature review. Combining institutional and public perceptions and knowledge of a social problem is helpful in not only establishing a more thorough understanding of the social problem and guiding policy decisions, but in exploring the experiences victims may face at the community level.

Forensic DNA methodologies have potential applications in the investigation of human trafficking cases. DNA and relationship testing may be useful for confirmation of biological relationship claims in immigration, identification of trafficked individuals who are missing persons, and family reunification of displaced individuals after mass disasters and conflicts. As these applications rely on the collection of DNA from non-criminals and potentially vulnerable individuals, questions arise as to how to address the ethical challenges of collection, security, and privacy of collected samples and DNA profiles. We administered a survey targeted to victims' advocates to gain preliminary understanding of perspectives regarding human trafficking definitions, DNA and sex workers, and perceived trust of authorities potentially involved in DNA collection. We asked respondents to consider the use of DNA for investigating adoption fraud, sex trafficking, and post-conflict child soldier cases. We found some key differences in perspectives on defining what qualifies as "trafficking." When we varied terminology between "sex worker" and "sex trafficking victim" we detected differences in perception on which authorities can be trusted. Respondents were supportive of the hypothetical models proposed to collect DNA. Most were favorable of DNA specimens being controlled by an authority outside of law enforcement. Participants voiced concerns focused on privacy, misuse of DNA samples and data, unintentional harms, data security, and infrastructure. These preliminary data indicate that while there is perceived value in programs to use DNA for investigating cases of human trafficking, these programs may need to consider levels of trust in authorities as their logistics are developed and implemented.

Adenosine receptor desensitization and trafficking.

Science.gov (United States)

Mundell, Stuart; Kelly, Eamonn

2011-05-01

As with the majority of G-protein-coupled receptors, all four of the adenosine receptor subtypes are known to undergo agonist-induced regulation in the form of desensitization and trafficking. These processes can limit the ability of adenosine receptors to couple to intracellular signalling pathways and thus reduce the ability of adenosine receptor agonists as well as endogenous adenosine to produce cellular responses. In addition, since adenosine receptors couple to multiple signalling pathways, these pathways may desensitize differentially, while the desensitization of one pathway could even trigger signalling via another. Thus, the overall picture of adenosine receptor regulation can be complex. For all adenosine receptor subtypes, there is evidence to implicate arrestins in agonist-induced desensitization and trafficking, but there is also evidence for other possible forms of regulation, including second messenger-dependent kinase regulation, heterologous effects involving G proteins, and the involvement of non-clathrin trafficking pathways such as caveolae. In this review, the evidence implicating these mechanisms is summarized for each adenosine receptor subtype, and we also discuss those issues of adenosine receptor regulation that remain to be resolved as well as likely directions for future research in this field.

2016-01-01

In an effort to combat human trafficking, the United States federal government and all fifty states passed new laws that criminalise human trafficking and support the identification and prosecution of human trafficking perpetrators. Despite the passage of these laws, only a small number of human trafficking cases have been prosecuted in the last fifteen years. Guided by the notion that prosecutors seek to avoid uncertainty when making decisions to pursue criminal prosecution, we explore how h...

Child trafficking and the European migration crisis: The role of forensic practitioners.

Science.gov (United States)

Obertová, Zuzana; Cattaneo, Cristina

2018-01-01

Trafficking in children is one of the worst forms of human rights violation and is categorised as a serious crime. Children at high risk of becoming victims of trafficking are runaways, children with a history of abuse, and migrant children. Internationally, cases of child trafficking are increasing the most in Europe, which is likely the result of the current migration crisis. In crises, preventing and combating human trafficking needs to be prioritized, considering that the aims of humanitarian action include saving lives, easing suffering and preserving human dignity. The involvement of forensic practitioners in investigations of cases of child trafficking mainly concerning the identification of victims may save lives and certainly alleviate suffering of the child victims and their families searching for them. Moreover, by aiding the prosecution process through thorough documentation and expert reporting forensic practitioners may contribute to the protection, rehabilitation and possibly compensation of the child victims, and thus to the restoration of their rights and dignity. So far, forensic practitioners were rarely specifically mentioned as actors in the counter-trafficking efforts in the multitude of policies, regulations, guidelines and recommendations concerning different aspects of child trafficking. This seems surprising considering that the expertise and experience of practitioners from forensic sciences including cyber forensics, document analysis, forensic biology, anthropology, and medicine can be utilised for gathering intelligence in cases of suspected human trafficking, for identifying the victims as well as perpetrators, and for securing evidence for legal proceedings as this paper shows. While this article mainly discusses the role of forensic pathologists and anthropologists, with a specific focus on the identification of child victims of trafficking in the context of the European migration crisis, the notions regarding the contribution of

Schwarz, Corinne; Unruh, Erik; Cronin, Katie; Evans-Simpson, Sarah; Britton, Hannah; Ramaswamy, Megha

2016-06-01

The medical sector presents a unique opportunity for identification and service to victims of human trafficking. In this article, we describe local and site-specific efforts to develop an intervention tool to be used in an urban hospital's emergency department in the midwestern United States. In the development of our tool, we focused on both identification and intervention to assist trafficked persons, through a largely collaborative process in which we engaged local stakeholders for developing site-specific points of intervention. In the process of developing our intervention, we highlight the importance of using existing resources and services in a specific community to address critical gaps in coverage for trafficked persons. For example, we focus on those who are victims of labor trafficking, in addition to those who are victims of sex trafficking. We offer a framework informed by rights-based approaches to anti-trafficking efforts that addresses the practical challenges of human trafficking victim identification while simultaneously working to provide resources and disseminate services to those victims.

VPS35 regulates developing mouse hippocampal neuronal morphogenesis by promoting retrograde trafficking of BACE1

Directory of Open Access Journals (Sweden)

Chun-Lei Wang

2012-10-01

VPS35, a major component of the retromer, plays an important role in the selective endosome-to-Golgi retrieval of membrane proteins. Dysfunction of retromer is a risk factor for neurodegenerative disorders, but its function in developing mouse brain remains poorly understood. Here we provide evidence for VPS35 promoting dendritic growth and maturation, and axonal protein transport in developing mouse hippocampal neurons. Embryonic hippocampal CA1 neurons suppressing Vps35 expression by in utero electroporation of its micro RNAs displayed shortened apical dendrites, reduced dendritic spines, and swollen commissural axons in the neonatal stage, those deficits reflecting a defective protein transport/trafficking in developing mouse neurons. Further mechanistic studies showed that Vps35 depletion in neurons resulted in an impaired retrograde trafficking of BACE1 (β1-secretase and altered BACE1 distribution. Suppression of BACE1 expression in CA1 neurons partially rescued both dendritic and axonal deficits induced by Vps35-deficiency. These results thus demonstrate that BACE1 acts as a critical cargo of retromer in vitro and in vivo, and suggest that VPS35 plays an essential role in regulating apical dendritic maturation and in preventing axonal spheroid formation in developing hippocampal neurons.

Identifying domestic and international sex-trafficking victims during human service provision.

Science.gov (United States)

Macy, Rebecca J; Graham, Laurie M

2012-04-01

Children, youth, and adults of both genders are sex trafficked into and throughout the United States every day. Regrettably, little attention has been given to how human service providers might identify the sex-trafficking victims they are likely to encounter. To address this knowledge gap, the authors review 20 documents with the aim of detecting and synthesizing service identification recommendations in the scientific literature, government reports, and documents produced by organizations working with sex-trafficking victims. The review shows consensus regarding identification recommendations, including (a) trafficking indicators, (b) victim interaction strategies, (c) immediate response strategies, and (d) child-specific information. The review also shows consensus regarding screening questions that are important for service providers to use in identifying sex-trafficking victims. These questions relate to the victims' safety, employment, living environment, and travel and immigration status in addition to specific questions used with children and youth. The review results offer human service providers a preliminary set of screening strategies and questions that can be used to identify sex-trafficking victims in the context of human services. Building on the review findings, the authors offer policy and research recommendations.

Global initiatives to tackle organ trafficking and transplant tourism.

Science.gov (United States)

Bagheri, Alireza; Delmonico, Francis L

2013-11-01

The increasing gap between organ supply and demand has opened the door for illegal organ sale, trafficking of human organs, tissues and cells, as well as transplant tourism. Currently, underprivileged and vulnerable populations in resource-poor countries are a major source of organs for rich patient-tourists who can afford to purchase organs at home or abroad. This paper presents a summary of international initiatives, such as World Health Organization's Principle Guidelines, The Declaration of Istanbul, Asian Task Force Recommendations, as well as UNESCO's and the United Nation's initiatives against trafficking of human organs, tissues, cells, and transplant tourism. Beyond the summary, it calls for more practical measures to be taken to implement the existing guidelines and recommendations, in order to prevent exploitation of the poor as organ providers. The paper suggests that an international legally binding agreement in criminalizing organ trafficking would be a step forward to bring a change in the global picture of organ trafficking and transplant tourism.

Full Text Available Worldwide, it is estimated that nearly 4 million people fall victim to people traffickers every year. Trafficking is carried out mainly by Organised Criminal Networks and the victims are forced into prostitution, illegal labour, domestic slavery and petty crime. ROSSITER & BENFIELD: The Role of Local Authorities in Addressing Human Trafficking CJLG May 2009 128 On 1 April 2009, the United Kingdom signed up to the Council of Europe Convention on Action against Trafficking in Human Beings.1 The Convention, which has to date been ratified by 20 European countries, is legally binding and aims to promote and protect the rights of victims who have been tricked or forced into leaving their homes, moved to another country, or within their own country, and then exploited. Whilst it is national governments who are signatories to the Council of Europe Convention, local authorities have a key role to play in its successful implementation.

Cellular membrane trafficking of mesoporous silica nanoparticles

Energy Technology Data Exchange (ETDEWEB)

Fang, I-Ju [Iowa State Univ., Ames, IA (United States)

2012-01-01

This dissertation mainly focuses on the investigation of the cellular membrane trafficking of mesoporous silica nanoparticles. We are interested in the study of endocytosis and exocytosis behaviors of mesoporous silica nanoparticles with desired surface functionality. The relationship between mesoporous silica nanoparticles and membrane trafficking of cells, either cancerous cells or normal cells was examined. Since mesoporous silica nanoparticles were applied in many drug delivery cases, the endocytotic efficiency of mesoporous silica nanoparticles needs to be investigated in more details in order to design the cellular drug delivery system in the controlled way. It is well known that cells can engulf some molecules outside of the cells through a receptor-ligand associated endocytosis. We are interested to determine if those biomolecules binding to cell surface receptors can be utilized on mesoporous silica nanoparticle materials to improve the uptake efficiency or govern the mechanism of endocytosis of mesoporous silica nanoparticles. Arginine-glycine-aspartate (RGD) is a small peptide recognized by cell integrin receptors and it was reported that avidin internalization was highly promoted by tumor lectin. Both RGD and avidin were linked to the surface of mesoporous silica nanoparticle materials to investigate the effect of receptor-associated biomolecule on cellular endocytosis efficiency. The effect of ligand types, ligand conformation and ligand density were discussed in Chapter 2 and 3. Furthermore, the exocytosis of mesoporous silica nanoparticles is very attractive for biological applications. The cellular protein sequestration study of mesoporous silica nanoparticles was examined for further information of the intracellular pathway of endocytosed mesoporous silica nanoparticle materials. The surface functionality of mesoporous silica nanoparticle materials demonstrated selectivity among the materials and cancer and normal cell lines. We aimed to determine

Trafficking (in Representations: Understanding the recurring appeal of victimhood and slavery in neoliberal times

Directory of Open Access Journals (Sweden)

Rutvica Andrijasevic

2016-09-01

Full Text Available Representations of trafficking and forced labour are pervasive within media, policymaking, and humanitarian debates, discourses and interventions. The terms exploitation and trafficking are increasingly used to characterise the work that migrants do in the sex industry and other irregular employment sectors. Of late, the notion of ‘modern slavery’ is on show in campaigns aiming to raise awareness about trafficking and funds for anti-trafficking initiatives among corporations and local enterprises as well as the general public. Celebrity interventions, militant documentaries, artistic works and fiction films have all become powerful vectors of the global distribution of the trafficking and ‘modern slavery’ rhetoric. These offer simplistic solutions to complex issues without challenging the structural and causal factors of inequality. Through fictional and narrow representations of ideal victims they tend to entrench racialised narratives and conflate all sex work with trafficking, which legitimates criminalising policies and interventions exacerbating the social vulnerability of sex workers. It is because of the under-researched role of representation in the development of anti-trafficking policies and initiatives that the Anti-Trafficking Review decided to devote a thematic issue on trafficking representations.

Protocol at the Crossroads: Rethinking anti-trafficking law from an Indian labour law perspective

Directory of Open Access Journals (Sweden)

Prabha Kotiswaran

2015-04-01

Full Text Available As we approach the fifteenth anniversary of the United Nations Trafficking Protocol, we can discern several phases of its diffusion, materialisation and interpretation in domestic criminal law regimes across the world. Although not exclusively preoccupied with sex work and sex trafficking anymore, the fact remains that the inordinate attention on trafficking in Western industrialised economies is disproportionate to the extent of the problem. Only 7% of the world’s 20.9 million forced labourers are in developed economies while 56% are in Asia Pacific. Yet in BRIC countries like India, with a substantial majority of the world’s trafficked victims and where 90% of all trafficking is domestic, trafficking has gained policy resonance only relatively recently. Even as India remains an active site for sexual humanitarianism with international and local abolitionist groups actively targeting sex workers, the article argues that less developed countries like India can play a crucial role in reorienting international anti-trafficking law and policy. Towards that goal, this article offers India’s bonded, contract and migrant labour laws as a robust labour law model against trafficking in contrast to the criminal justice model propagated by the Trafficking Protocol worldwide.

Rapid glutamate receptor 2 trafficking during retinal degeneration

Directory of Open Access Journals (Sweden)

Lin Yanhua

2012-02-01

Full Text Available Abstract Background Retinal degenerations, such as age-related macular degeneration (AMD and retinitis pigmentosa (RP, are characterized by photoreceptor loss and anomalous remodeling of the surviving retina that corrupts visual processing and poses a barrier to late-stage therapeutic interventions in particular. However, the molecular events associated with retinal remodeling remain largely unknown. Given our prior evidence of ionotropic glutamate receptor (iGluR reprogramming in retinal degenerations, we hypothesized that the edited glutamate receptor 2 (GluR2 subunit and its trafficking may be modulated in retinal degenerations. Results Adult albino Balb/C mice were exposed to intense light for 24 h to induce light-induced retinal degeneration (LIRD. We found that prior to the onset of photoreceptor loss, protein levels of GluR2 and related trafficking proteins, including glutamate receptor-interacting protein 1 (GRIP1 and postsynaptic density protein 95 (PSD-95, were rapidly increased. LIRD triggered neuritogenesis in photoreceptor survival regions, where GluR2 and its trafficking proteins were expressed in the anomalous dendrites. Immunoprecipitation analysis showed interaction between KIF3A and GRIP1 as well as PSD-95, suggesting that KIF3A may mediate transport of GluR2 and its trafficking proteins to the novel dendrites. However, in areas of photoreceptor loss, GluR2 along with its trafficking proteins nearly vanished in retracted retinal neurites. Conclusions All together, LIRD rapidly triggers GluR2 plasticity, which is a potential mechanism behind functionally phenotypic revisions of retinal neurons and neuritogenesis during retinal degenerations.

Astrocytic Pathological Calcium Homeostasis and Impaired Vesicle Trafficking in Neurodegeneration

Directory of Open Access Journals (Sweden)

Nina Vardjan

2017-02-01

Full Text Available Although the central nervous system (CNS consists of highly heterogeneous populations of neurones and glial cells, clustered into diverse anatomical regions with specific functions, there are some conditions, including alertness, awareness and attention that require simultaneous, coordinated and spatially homogeneous activity within a large area of the brain. During such events, the brain, representing only about two percent of body mass, but consuming one fifth of body glucose at rest, needs additional energy to be produced. How simultaneous energy procurement in a relatively extended area of the brain takes place is poorly understood. This mechanism is likely to be impaired in neurodegeneration, for example in Alzheimer’s disease, the hallmark of which is brain hypometabolism. Astrocytes, the main neural cell type producing and storing glycogen, a form of energy in the brain, also hold the key to metabolic and homeostatic support in the central nervous system and are impaired in neurodegeneration, contributing to the slow decline of excitation-energy coupling in the brain. Many mechanisms are affected, including cell-to-cell signalling. An important question is how changes in cellular signalling, a process taking place in a rather short time domain, contribute to the neurodegeneration that develops over decades. In this review we focus initially on the slow dynamics of Alzheimer’s disease, and on the activity of locus coeruleus, a brainstem nucleus involved in arousal. Subsequently, we overview much faster processes of vesicle traffic and cytosolic calcium dynamics, both of which shape the signalling landscape of astrocyte-neurone communication in health and neurodegeneration.

Effect of serum proteins on polystyrene nanoparticle uptake and intracellular trafficking in endothelial cells

International Nuclear Information System (INIS)

Guarnieri, Daniela; Guaccio, Angela; Fusco, Sabato; Netti, Paolo A.

2011-01-01

The physico-chemical properties of nanoparticles (NPs), such as small dimensions, surface charge and surface functionalization, control their capability to interact with cells and, in particular, with sub-cellular components. This interaction can be also influenced by the adsorption of molecules present in biological fluids, like blood, on NP surface. Here, we analysed the effect of serum proteins on 49 and 100 nm red fluorescent polystyrene NP uptake in porcine aortic endothelial (PAE) cells, as a model for vascular transport. To this aim, NP uptake kinetic, endocytic pathway and intracellular trafficking were studied by monitoring NPs inside cells through confocal microscopy and multiple particle tracking (MPT). We demonstrated that NPs are rapidly internalized by cells in serum-free (SF) medium, according to a saturation kinetic. Conversely, in 10% foetal bovine serum-enriched (SE) medium, NP uptake rate results drastically reduced. Moreover, NP internalization depends on an active endocytic mechanism that does not involve clathrin- and caveolae-mediated vesicular transport, in both SE and SF media. Furthermore, MPT data indicate that NP intracellular trafficking is unaffected by protein presence. Indeed, approximately 50–60% of internalized NPs is characterized by a sub-diffusive behaviour, whereas the remaining fraction shows an active motion. These findings demonstrate that the unspecific protein adsorption on NP surface can affect cellular uptake in terms of internalization kinetics, but it is not effective in controlling active and cellular-mediated uptake mechanisms of NPs and their intracellular routes.

2018-01-01

The trafficking of persons around the world is a serious violation of human rights and manifestation of social injustice. It disproportionately affects women and children worldwide. Given the values of the social work profession and the prevalence of trafficking, it is essential to understand the current literature on human trafficking in social work journals. Using the PRISMA method, this systematic review (n = 94 articles) of human trafficking in social work journals found the following: more focus on sex trafficking than other forms of trafficking; a lack of a clear conceptualization and definition on the entire spectrum of trafficking; a lack of evidence-informed empirical research to inform programs, practice, and policy; and a dearth of recommendations for social work education. Specific implications for social work policy, research, practice, and education are highlighted and discussed.

Human trafficking is a significant human rights problem that is often associated with psychological and physical violence. There is no demographic that is spared from human trafficking. Traffickers maintain control of victims through physical, sexual, and emotional violence and manipulation. Because victims of trafficking seek medical attention for the medical and psychological consequences of assault and neglected health conditions, emergency clinicians are in a unique position to recognize victims and intervene. Evaluation of possible trafficking victims is challenging because patients who have been exploited rarely self-identify. This article outlines the clinical approach to the identification and treatment of a potential victim of human trafficking in the emergency department. Emergency practitioners should maintain a high index of suspicion when evaluating patients who appear to be at risk for abuse and violence, and assess for specific indicators of trafficking. Potential victims should be evaluated with a multidisciplinary and patient-centered technique. Furthermore, emergency practitioners should be aware of national and local resources to guide the approach to helping identified victims. Having established protocols for victim identification, care, and referrals can greatly facilitate health care providers' assisting this population.

Yousaf, Farhan Navid; Purkayastha, Bandana

2016-05-01

Although success of organ transplants reflects advances in medical procedures, the success has generated debates about the ethical standards and policies that govern transplants, especially the acquisition of organs for transplants. We focus on laws, policies, and organ trafficking to highlight the interdisciplinary perspectives that can shape our understanding of transplantation as a social phenomenon. We discuss international policies and country-specific legislation from Pakistan to point to gaps and their implications for protecting vulnerable people who are exploited for organ removal. International collaboration and the legal framework need to be strengthened to fight the menace globally and to deal with the cases of organ trafficking within the legal ambit of human trafficking so that the rights of victims are upheld by states, justice systems, and ultimately medical establishments and practitioners.

Full Text Available Having worked on human trafficking issues since the late 1990s, I have been fortunate to observe the rapid development of the infrastructure necessary to respond to these crimes. In 1999, a time of much concern about ‘mail order brides’ and debates about the differences between human trafficking and smuggling, I published a report noting that: In Australia, as in other countries of the world, limited evidence is available about the nature and incidence of trafficking in persons. There is some anecdotal evidence of trafficking activity occurring in various industries, including hospitality, manufacturing, and agriculture. The sector that has received the most media attention, however, is the sex industry.

Distinct human and mouse membrane trafficking systems for sweet taste receptors T1r2 and T1r3.

Shimizu, Madoka; Goto, Masao; Kawai, Takayuki; Yamashita, Atsuko; Kusakabe, Yuko

2014-01-01

The sweet taste receptors T1r2 and T1r3 are included in the T1r taste receptor family that belongs to class C of the G protein-coupled receptors. Heterodimerization of T1r2 and T1r3 is required for the perception of sweet substances, but little is known about the mechanisms underlying this heterodimerization, including membrane trafficking. We developed tagged mouse T1r2 and T1r3, and human T1R2 and T1R3 and evaluated membrane trafficking in human embryonic kidney 293 (HEK293) cells. We found that human T1R3 surface expression was only observed when human T1R3 was coexpressed with human T1R2, whereas mouse T1r3 was expressed without mouse T1r2 expression. A domain-swapped chimera and truncated human T1R3 mutant showed that the Venus flytrap module and cysteine-rich domain (CRD) of human T1R3 contain a region related to the inhibition of human T1R3 membrane trafficking and coordinated regulation of human T1R3 membrane trafficking. We also found that the Venus flytrap module of both human T1R2 and T1R3 are needed for membrane trafficking, suggesting that the coexpression of human T1R2 and T1R3 is required for this event. These results suggest that the Venus flytrap module and CRD receive taste substances and play roles in membrane trafficking of human T1R2 and T1R3. These features are different from those of mouse receptors, indicating that human T1R2 and T1R3 are likely to have a novel membrane trafficking system.

HIV-1 Envelope Glycoprotein Trafficking through the Endosomal Recycling Compartment Is Required for Particle Incorporation.

The human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein (Env) encodes specific trafficking signals within its long cytoplasmic tail (CT) that regulate incorporation into HIV-1 particles. Rab11-family interacting protein 1C (FIP1C) and Rab14 are host trafficking factors required for Env particle incorporation, suggesting that Env undergoes sorting from the endosomal recycling compartment (ERC) to the site of particle assembly on the plasma membrane. We disrupted outward sorting from the ERC by expressing a C-terminal fragment of FIP1C (FIP1C 560-649 ) and examined the consequences on Env trafficking and incorporation into particles. FIP1C 560-649 reduced cell surface levels of Env and prevented its incorporation into HIV-1 particles. Remarkably, Env was trapped in an exaggerated perinuclear ERC in a CT-dependent manner. Mutation of either the Yxxϕ endocytic motif or the YW 795 motif in the CT prevented Env trapping in the ERC and restored incorporation into particles. In contrast, simian immunodeficiency virus SIVmac239 Env was not retained in the ERC, while substitution of the HIV-1 CT for the SIV CT resulted in SIV Env retention in this compartment. These results provide the first direct evidence that Env traffics through the ERC and support a model whereby HIV-1 Env is specifically targeted to the ERC prior to FIP1C- and CT-dependent outward sorting to the particle assembly site on the plasma membrane. IMPORTANCE The HIV envelope protein is an essential component of the viral particle. While many aspects of envelope protein structure and function have been established, the pathway it follows in the cell prior to reaching the site of particle assembly is not well understood. The envelope protein has a very long cytoplasmic tail that interacts with the host cell trafficking machinery. Here, we utilized a truncated form of the trafficking adaptor FIP1C protein to arrest the intracellular transport of the envelope protein, demonstrating that it becomes

One of the major mechanisms for GPCR regulation involves their endocytic trafficking, which serves to internalize the receptors from the plasma membrane and thereby attenuate G protein-dependent signaling. However, there is accumulating evidence to suggest that GPCRs can signal...... independently of G proteins, as well as from intracellular compartments including endosomes. It is in this context that receptor internalization and intracellular trafficking have attracted renewed interest within the GPCR field.

Key roles of Arf small G proteins and biosynthetic trafficking for animal development.

Science.gov (United States)

Rodrigues, Francisco F; Harris, Tony J C

2017-04-14

Although biosynthetic trafficking can function constitutively, it also functions specifically for certain developmental processes. These processes require either a large increase to biosynthesis or the biosynthesis and targeted trafficking of specific players. We review the conserved molecular mechanisms that direct biosynthetic trafficking, and discuss how their genetic disruption affects animal development. Specifically, we consider Arf small G proteins, such as Arf1 and Sar1, and their coat effectors, COPI and COPII, and how these proteins promote biosynthetic trafficking for cleavage of the Drosophila embryo, the growth of neuronal dendrites and synapses, extracellular matrix secretion for bone development, lumen development in epithelial tubes, notochord and neural tube development, and ciliogenesis. Specific need for the biosynthetic trafficking system is also evident from conserved CrebA/Creb3-like transcription factors increasing the expression of secretory machinery during several of these developmental processes. Moreover, dysfunctional trafficking leads to a range of developmental syndromes.

Some Experience with Illicit Trafficking of Radioactive Materials in Tanzania

International Nuclear Information System (INIS)

Ngaile, J.E.; Banzi, F.P.; Kifanga, L.D.

2008-01-01

Illicit trafficking of radioactive materials (orphan sources or disuse sources) is of global concern. Reports on the IAEA Illicit Trafficking Data Base (ITDB) indicates increasing trend of incidents recorded in more than 40 countries on six continents[1]. It is suspected that nuclear trafficking is fueled by nuclear terrorism and is a threat for increasing illegal trade in nuclear and radioactive materials to manufacture Radiological Disposal Devices (RDD)- dirty bombs. As such, the international co-operative efforts are needed to uncover and combat nuclear trafficking in order to minimize its consequences such as external radiation exposure of persons from source to various radiation levels during illicit movement and after seizure; rupture of source leading to internal exposure of persons and environmental contamination. Although accidents with radioactive materials have not occurred in the United Republic of Tanzania (URT), incidents of illicit trafficking and unauthorized possession of radioactive materials has occurred thus prompting the Tanzania Atomic Energy Commission (TAEC) to strengthen its nuclear security of nuclear and radioactive material in the URT. Nuclear faclities and radioactive sources lacks adequate physical protection against theft, fire or different forms of unauthorized access. Tanzaniaia has recorded about thirteen (13) illicit trafficking incidents of radioactive between 1996-2006. Caesium-137, Uranium-238; and Uranium oxide standard and Radium-226 with activity ranging from low to significantly high were among the radiounuclides which were intercepted. Most of these incidents had their original outside Tanzania. The incidents were uncovered by informers in cooperation with the police. Despite the fact that the management of these incidents by the police were adequate, it was observed that there is an inadequate radiation protection arrangements during transport of seized sources; lack of precautions for safety when handling seized

Editorial: The Presence of the Past: Lessons of history for anti-trafficking work

2017-09-01

Full Text Available This issue of the Anti-Trafficking Review is concerned with some of the histories that created, and that continue to shape, both the present-day phenomena discussed under the rubric of trafficking, and the contemporary discourse of trafficking itself. One such history is that of transatlantic slavery. Since the millennium, numerous NGOs have been founded in the US, Australia and Europe with a mission to end what they call ‘modern slavery’. Their campaigns have overlapped with, and played a significant role in shaping, the development of media, NGO, policy and political discourse on human trafficking, which is, according to the antislavery NGO Free the Slaves, ‘the modern day slave trade—the process of enslaving a person’.1 In this discourse, the history of transatlantic slavery is invoked by means of visual as well as textual references in order to emphasise the severity of trafficking (and other phenomena included under the umbrella of ‘modern slavery’ as a human rights violation. The message has been communicated so effectively that although in international law slavery is held to be only one of several possible outcomes of trafficking, in the anti-trafficking rhetoric emanating from national and international policy agencies, as well as NGOs, trafficking is now frequently said to be ‘modern slavery’.2

Trafficking of Women in Mexico and Their Health Risk: Issues and Problems

Arun Kumar Acharya

2015-02-01

Full Text Available Trafficking in women is one of the most corrosive forms of human rights violation. It results in the gradual destruction of a woman’s personal identity and her right to live as a free human. The victim is subjected to violence, humiliation and violation of her personal integrity, which may result in life threatening diseases like HIV/AIDS, STDs or lifelong trauma, drug addiction or personality disintegration. It can also be seen as denial of the right to liberty and security of the person, and the right to freedom from torture, violence, cruelty or degrading treatment. Over the last few decades, international trafficking of women has been given more attention by researchers. However at present internal trafficking is drawing more attention and concern from researchers. The complexity of obtaining visas and strict patrolling on international borders has caused a boom of internal trafficking around the world. Thus, the current paper aims to investigate trafficking of women for sexual exploitation including the recruitment process, methods of trafficking and working conditions of the victims; as well as to explore the determinants of sexual violence and its impact on the health of trafficked women in Monterrey, Mexico. For the present study a total of 60 women were interviewed using a snowball method between 2007 and 2013.

An Ecological Approach Toward Prevention and Care of Victims of Domestic Minor Sex Trafficking.

Science.gov (United States)

Sanchez, Rosario V; Pacquiao, Dula F

Sex trafficking is a widespread form of human trafficking that exists globally. The forced sexual exploitation of young women for profit at the hands of traffickers is a human rights violation. Sex trafficking is a form of modern-day slavery where youths are sold as a commodity. It is difficult to determine the wide range of negative health outcomes associated with domestic minor sex trafficking due to the hidden nature of the crime and its lack of statistical data to determine prevalence. Viewing domestic minor sex trafficking through an ecological lens assists in the understanding of the multiple complex interactions between victims, their relationships, and environments that influence their health. Forensic nurses are poised as experts in the healthcare of vulnerable populations and possess the knowledge to understand that social determinants of vulnerability depend on the distinct setting or environment where victims of sex trafficking reside and how different factors affect their victimology, resilience, and well-being.

Human Trafficking and the Rome Statute of the International Criminal Court

Directory of Open Access Journals (Sweden)

CLARE FRANCES MORAN

2014-12-01

Full Text Available The case for extending the reach of the Rome Statute to the crime of human trafficking has not yet been made in detail. The brutality which occurs when human beings are trafficked by criminal gangs is of an equally egregious nature as the other crimes covered by the Rome Statute and yet it does not fall within the remit of the International Criminal Court. Such trafficking may also fall outwith the definition of slavery as a crime against humanity, particularly given the State policy threshold set by the Statute. This paper seeks to explore the viability of the inclusion of human trafficking as a discrete international crime within the Rome Statute as a response to this loophole.

Squalestatin alters the intracellular trafficking of a neurotoxic prion peptide

Directory of Open Access Journals (Sweden)

Williams Alun

2007-11-01

Full Text Available Abstract Background Neurotoxic peptides derived from the protease-resistant core of the prion protein are used to model the pathogenesis of prion diseases. The current study characterised the ingestion, internalization and intracellular trafficking of a neurotoxic peptide containing amino acids 105–132 of the murine prion protein (MoPrP105-132 in neuroblastoma cells and primary cortical neurons. Results Fluorescence microscopy and cell fractionation techniques showed that MoPrP105-132 co-localised with lipid raft markers (cholera toxin and caveolin-1 and trafficked intracellularly within lipid rafts. This trafficking followed a non-classical endosomal pathway delivering peptide to the Golgi and ER, avoiding classical endosomal trafficking via early endosomes to lysosomes. Fluorescence resonance energy transfer analysis demonstrated close interactions of MoPrP105-132 with cytoplasmic phospholipase A2 (cPLA2 and cyclo-oxygenase-1 (COX-1, enzymes implicated in the neurotoxicity of prions. Treatment with squalestatin reduced neuronal cholesterol levels and caused the redistribution of MoPrP105-132 out of lipid rafts. In squalestatin-treated cells, MoPrP105-132 was rerouted away from the Golgi/ER into degradative lysosomes. Squalestatin treatment also reduced the association between MoPrP105-132 and cPLA2/COX-1. Conclusion As the observed shift in peptide trafficking was accompanied by increased cell survival these studies suggest that the neurotoxicity of this PrP peptide is dependent on trafficking to specific organelles where it activates specific signal transduction pathways.

Human Trafficking and Sexual Servitude: Organised Crime’s Involvement in Australia

Directory of Open Access Journals (Sweden)

Mark Langhorn

2018-03-01

Full Text Available This study examined the context of organised crime groups that traffic in people for the Australian sex industry. It is a qualitative study of twenty-one cases of human trafficking. The study found that criminal networks preyed on vulnerable females from countries such as Thailand, South Korea, and China. Victims were deceptively recruited with the cost of their travel to Australia held against them as a highly inflated debt. As a result, they find themselves forced into sex work to repay the debt. This study examined the attributes of the organised crime syndicates involved in the people trafficking and discussed the context in which they operate in Australia. The study used the Sleipnir framework to analyse organised crime groups and it is recommended that the Sleipnir model is integrated into future law enforcement activities in respect of human trafficking. The introduction of a standardised data and statistical collection tool in respect of human trafficking would provide law enforcement and intelligence agencies with a conceptual framework and a greater comprehensive description of human trafficking.

Human trafficking is an increasingly well-recognized human rights violation that is estimated to involve more than 2 million victims worldwide each year. The health consequences of this issue bring victims into contact with health systems and healthcare providers, thus providing the potential for identification and intervention. A robust healthcare response, however, requires a healthcare workforce that is aware of the health impact of this issue; educated about how to identify and treat affected individuals in a compassionate, culturally aware, and trauma-informed manner; and trained about how to collaborate efficiently with law enforcement, case management, and advocacy partners. This article describes existing educational offerings about human trafficking designed for a healthcare audience and makes recommendations for further curriculum development. A keyword search and structured analysis of peer-reviewed and gray literature, conducted in 2011 and 2012, yielded 27 items that provide basic guidance to health professionals on human trafficking. The 27 resources differed substantially in format, length, scope, and intended audience. Topic areas covered by these resources included trafficking definitions and scope, health consequences, victim identification, appropriate treatment, referral to services, legal issues, and security. None of the educational resources has been rigorously evaluated. There is a clear need to develop, implement, and evaluate high-quality education and training programs that focus on human trafficking for healthcare providers.

Monitoring and Evaluation of Human Trafficking Partnerships in England and Wales

Directory of Open Access Journals (Sweden)

Ruth Van Dyke

2017-04-01

Full Text Available In the United Kingdom, human trafficking and, more recently, modern slavery has been pushed up the political and policy agenda. At the same time, partnership working has been promoted at international and national levels in order to encourage a more holistic response to trafficking. This article examines the nature of the evidence collected to monitor and evaluate the activities and outcomes of organisations involved in a number of human trafficking partnerships in England and Wales. Underpinning this analysis is the ‘4 Ps’ approach to tackling human trafficking: Prevention, Protection, Prosecution and Partnership. Based on interviews with a variety of actors working in different partner bodies, limitations of evidence in relation to both monitoring activities as well as evaluating outcomes emerged. These relate to inadequate data collection, lack of robust methods of data collection, untested assumptions, the complexity of gathering evidence which reflect human welfare oriented goals, and the sharing of evidence between partner organisations. A key finding is that current data and methods of data collection are inadequate for the purpose of measuring the effectiveness of anti-trafficking initiatives and partnerships. Another key finding is the way in which partnerships challenged received outcomes and expanded their focus beyond victims of trafficking or criminal justice goals. Finally, I explore whether criminal justice outcomes can be leveraged to foster deterrence, by interrogating what evidence might be needed.

Purity, Victimhood and Agency: Fifteen years of the UN Trafficking Protocol

Directory of Open Access Journals (Sweden)

Marjan Wijers

2015-04-01

Full Text Available When the women’s movement reverted back to the nineteenth-century Victorian concept of ‘trafficking in women’ to address abuses of migrant women in the sex industry, it unwittingly adopted not only a highly morally biased concept—dividing women into innocent victims in need of rescue and guilty ones who can be abused with impunity—but also one with racist and nationalistic overtones. Despite efforts to counter these flaws, this inheritance continues to define the debate on trafficking today, exemplified by the distinction made by the United Nations Trafficking Protocol between so-called ‘sexual exploitation’ and ‘labour exploitation’ and its focus on the aspects of recruitment and movement. As a result, its implementation in the last fifteen years has led to a range of oppressive measures against sex workers and migrants in the name of combating trafficking. The focus on the purity and victimhood of women, coupled with the protection of national borders, not only impedes any serious effort to address the exploitation of human beings under forced labour and slavery-like conditions, but actually causes harm. The call of the anti-trafficking movement for a human rights-based approach does not necessarily solve these fundamental problems, as it tends to restrict itself to protecting the rights of trafficked persons, while neglecting or even denying the human rights of sex workers and migrants.

Forces of Habit: Global SOF's Role in Countering Illicit Drug Trafficking

Full Text Available Illicit drug trafficking is a prominent national security issue in a globalizing world. Drug trafficking intersects with major security issues such as rogue and narco-states, weak and failing states, insurgencies and terrorism, transnational organized crime and protracted intrastate conflicts. These are the same issues that sets the operational environment for the deployment of SOF. Rather than treating drug trafficking as a singular and separate security issue, global SOF counternarcotics operations must adapt previous approaches to new realities.

Etiological Aspects of Human Trafficking in Kosovo

2017-08-01

Full Text Available Human trafficking is considered one of the most serious criminal offences, which is presented as a contemporary form of slavery and which implies the most brutal violation of basic human rights, which are guaranteed by international and law and national law. The phenomenon of human trafficking is present in many countries in transition (such as Kosovo, namely in those countries which were affected by internal political, economic, social, educational, etc. changes, and in such situations the perpetrators of this offense are in a very favorable position to victimize society. Therefore, this paper will focus on external criminogenic factors that influence the growth of this negative phenomenon, including the difficult economic situation, poverty and unemployment, poor housing, migration of people, domestic violence, the impact of mass media in society, lack of border control and insufficient effectiveness of institutions to deal with law enforcement. The paper is based on literature review, statistical data and interviews by treating the subject theoretically, legislatively and practically. To successfully fight against human trafficking, relevant authorities should more closely approach the etiological treatment of this negative phenomenon.

Structure-Function Correlation Analysis of Connexin50 Missense Mutations Causing Congenital Cataract: Electrostatic Potential Alteration Could Determine Intracellular Trafficking Fate of Mutants

Directory of Open Access Journals (Sweden)

Devroop Sarkar

2014-01-01

Full Text Available Connexin50 (Cx50 mutations are reported to cause congenital cataract probably through the disruption of intercellular transport in the lens. Cx50 mutants that undergo mistrafficking have generally been associated with failure to form functional gap junction channels; however, sometimes even properly trafficked mutants were found to undergo similar consequences. We hereby wanted to elucidate any structural bases of the varied functional consequences of Cx50 missense mutations through in silico approach. Computational studies have been done based on a Cx50 homology model to assess conservation, solvent accessibility, and 3-dimensional localization of mutated residues as well as mutation-induced changes in surface electrostatic potential, H-bonding, and steric clash. This was supplemented with meta-analysis of published literature on the functional properties of connexin missense mutations. Analyses revealed that the mutation-induced critical alterations of surface electrostatic potential in Cx50 mutants could determine their fate in intracellular trafficking. A similar pattern was observed in case of mutations involving corresponding conserved residues in other connexins also. Based on these results the trafficking fates of 10 uncharacterized Cx50 mutations have been predicted. Further experimental analyses are needed to validate the observed correlation.

Do Evidence-Based Approaches Alienate Canadian Anti-Trafficking Funders?

Full Text Available As a sex worker support organisation, SWAN (Supporting Women’s Alternatives Network Vancouver’s relationship to anti-trafficking funding remains ambivalent, particularly given the history of anti-trafficking measures that have jeopardised the rights of sex workers. In this article, we share how we, as a small grassroots group, attempt to work through these ambivalences in dialogue with donors. Although SWAN Vancouver works with women who are often perceived to be trafficked (i.e. Asian women in sex work, it is rare for members of SWAN Vancouver to come across any case in the sex-work sector that has the hallmarks of trafficking, such as coerced work. Instead, our anti-trafficking work has mainly involved identifying the harms and human rights violations caused by repressive or misguided anti-trafficking measures. We reflect on our dialogue with two Canadian funders (a federal government agency and a national public foundation that have considerable resources and immense power to influence what anti-trafficking practices are implemented in Canada. We analyse how these two funders and their adoption of an anti-prostitution analysis of trafficking will likely result in punitive consequences for immigrant sex workers, and therefore increase the need to assist women who have been anti-trafficked rather than trafficked. ¿Están los financiadores canadienses contra la trata alejados del enfoque basado en la evidencia? Resumen Como una organización que apoya a los trabajadores sexuales, la relación entre SWAN (Red Alternativa de Apoyo a las Mujeres y los financiadores contra la trata en Vancouver es contradictoria, sobre todo teniendo en cuenta la historia de las medidas contra la trata que han puesto en peligro los derechos de los trabajadores sexuales.

Discussions of key findings include (a outcomes of a criminal case using a new human trafficking statute on fraud in foreign contracting and a civil suit, (b how online prostitution ads are used to market victims to sex buyers using ethnicity of the victims and age and social standing of the sex buyers, and (c how mothers of victims are involved in locating their daughters and making reports to the police that initiated investigations.

LRRK2 affects vesicle trafficking, neurotransmitter extracellular level and membrane receptor localization.

Directory of Open Access Journals (Sweden)

Rossana Migheli

Full Text Available The leucine-rich repeat kinase 2 (LRRK2 gene was found to play a role in the pathogenesis of both familial and sporadic Parkinson's disease (PD. LRRK2 encodes a large multi-domain protein that is expressed in different tissues. To date, the physiological and pathological functions of LRRK2 are not clearly defined. In this study we have explored the role of LRRK2 in controlling vesicle trafficking in different cellular or animal models and using various readouts. In neuronal cells, the presence of LRRK2(G2019S pathological mutant determines increased extracellular dopamine levels either under basal conditions or upon nicotine stimulation. Moreover, mutant LRRK2 affects the levels of dopamine receptor D1 on the membrane surface in neuronal cells or animal models. Ultrastructural analysis of PC12-derived cells expressing mutant LRRK2(G2019S shows an altered intracellular vesicle distribution. Taken together, our results point to the key role of LRRK2 to control vesicle trafficking in neuronal cells.

Hospitalization is one of the few circumstances in which the lives of trafficking victims intersect with the general population. Based on survivor testimonies, the majority of human trafficking victims may receive medical treatment in a hospital's emergency department while in captivity. With evidenced-based training, ED personnel have a better opportunity to screen persons who are being trafficked and intervene on their behalf. This project examined the efficacy of an innovative, evidence-based online training module (HTEmergency.com) created by the project team. Participants completed a pre-survey to determine learning needs and a post-survey to determine the effectiveness of the online education. The learning module contained a PowerPoint presentation, identification and treatment guidelines, and 2 realistic case studies. Data were collected among ED personnel in 2 suburban hospitals located near a northeast metropolitan city. Seventy-five employees participated in the survey and education. Staff completing the education included nurses, physicians, nurse practitioners/physician assistants, registration, and ED technicians. Results indicated that 89% of participants had not received previous human trafficking training. Less than half of the participants stated that they had a comprehensive understanding of human trafficking before the intervention, with an increase to 93% after education. The training module significantly increased confidence in identification (from an average confidence level of 4/10 to 7/10) and treatment (from an average confidence level of 4/10 to 8/10) of human trafficking victims within the emergency department; 96% found the educational module to be useful in their work setting. Participants reported that they are more confident in identifying a possible trafficking victim and are more likely to screen patients for human trafficking after participation in the online training module.

Redefining the essential trafficking pathway for outer membrane lipoproteins

Science.gov (United States)

Grabowicz, Marcin; Silhavy, Thomas J.

2017-01-01

The outer membrane (OM) of Gram-negative bacteria is a permeability barrier and an intrinsic antibiotic resistance factor. Lipoproteins are OM components that function in cell wall synthesis, diverse secretion systems, and antibiotic efflux pumps. Moreover, each of the essential OM machines that assemble the barrier requires one or more lipoproteins. This dependence is thought to explain the essentiality of the periplasmic chaperone LolA and its OM receptor LolB that traffic lipoproteins to the OM. However, we show that in strains lacking substrates that are toxic when mislocalized, both LolA and LolB can be completely bypassed by activating an envelope stress response without compromising trafficking of essential lipoproteins. We identify the Cpx stress response as a monitor of lipoprotein trafficking tasked with protecting the cell from mislocalized lipoproteins. Moreover, our findings reveal that an alternate trafficking pathway exists that can, under certain conditions, bypass the functions of LolA and LolB, implying that these proteins do not perform any truly essential mechanistic steps in lipoprotein trafficking. Instead, these proteins’ key function is to prevent lethal accumulation of mislocalized lipoproteins. PMID:28416660

Pascalev, Assya; Van Assche, Kristof; Sándor, Judit; Codreanu, Natalia; Naqvi, Anwar; Gunnarson, Martin; Frunza, Mihaela; Yankov, Jordan

2016-02-01

This report presents a comprehensive set of recommendations for protection of human beings who are trafficked for the purpose of organ removal or are targeted for such trafficking. Developed by an interdisciplinary group of international experts under the auspices of the project Trafficking in Human Beings for the Purpose of Organ Removal (also known as the HOTT project), these recommendations are grounded in the view that an individual who parts with an organ for money within an illegal scheme is ipso facto a victim and that the crime of trafficking in human beings for the purpose of organ removal (THBOR) intersects with the crime of trafficking in organs. Consequently, the protection of victims should be a priority for all actors involved in antitrafficking activities: those combating organ-related crimes, such as health organizations and survivor support services, and those combating trafficking in human beings, such as the criminal justice sectors. Taking into account the special characteristics of THBOR, the authors identify 5 key stakeholders in the protection of human beings trafficked for organ removal or targeted for such trafficking: states, law enforcement agencies and judiciary, nongovernmental organizations working in the areas of human rights and antitrafficking, transplant centers and health professionals involved in transplant medicine, and oversight bodies. For each stakeholder, the authors identify key areas of concern and concrete measures to identify and protect the victims of THBOR. The aim of the recommendations is to contribute to the development of a nonlegislative response to THBOR, to promote the exchange of knowledge and best practices in the area of victim protection, and to facilitate the development of a policy-driven action plan for the protection of THBOR victims in the European Union and worldwide.

GABA type a receptor trafficking and the architecture of synaptic inhibition.

Science.gov (United States)

Lorenz-Guertin, Joshua M; Jacob, Tija C

2018-03-01

Ubiquitous expression of GABA type A receptors (GABA A R) in the central nervous system establishes their central role in coordinating most aspects of neural function and development. Dysregulation of GABAergic neurotransmission manifests in a number of human health disorders and conditions that in certain cases can be alleviated by drugs targeting these receptors. Precise changes in the quantity or activity of GABA A Rs localized at the cell surface and at GABAergic postsynaptic sites directly impact the strength of inhibition. The molecular mechanisms constituting receptor trafficking to and from these compartments therefore dictate the efficacy of GABA A R function. Here we review the current understanding of how GABA A Rs traffic through biogenesis, plasma membrane transport, and degradation. Emphasis is placed on discussing novel GABAergic synaptic proteins, receptor and scaffolding post-translational modifications, activity-dependent changes in GABA A R confinement, and neuropeptide and neurosteroid mediated changes. We further highlight modern techniques currently advancing the knowledge of GABA A R trafficking and clinically relevant neurodevelopmental diseases connected to GABAergic dysfunction. © 2017 Wiley Periodicals, Inc.

"The perfect business": human trafficking and Lao-Thai cross-border migration.

Science.gov (United States)

Molland, Sverre

2010-01-01

Over the past few years some governments and development organizations have increasingly articulated cross-border mobility as "trafficking in persons". The notion of a market where traffickers prey on the "supply" of migrants that flows across international borders to meet the "demand" for labour has become a central trope among anti-trafficking development organizations. This article problematizes such economism by drawing attention to the oscillating cross-border migration of Lao sex workers within a border zone between Laos and Thailand. It illuminates the incongruity between the recruitment of women into the sex industry along the Lao-Thai border and the market models that are employed by the anti-trafficking sector. It discusses the ways in which these cross-border markets are conceived in a context where aid programming is taking on an increasingly important role in the politics of borders. The author concludes that allusions to ideal forms of knowledge (in the guise of classic economic theory) and an emphasis on borders become necessary for anti-trafficking programmes in order to make their object of intervention legible as well as providing post-hoc rationalizations for their continuing operation.

Structure of Human B12 Trafficking Protein CblD Reveals Molecular Mimicry and Identifies a New Subfamily of Nitro-FMN Reductases.

In mammals, B12 (or cobalamin) is an essential cofactor required by methionine synthase and methylmalonyl-CoA mutase. A complex intracellular pathway supports the assimilation of cobalamin into its active cofactor forms and delivery to its target enzymes. MMADHC (the methylmalonic aciduria and homocystinuria type D protein), commonly referred to as CblD, is a key chaperone involved in intracellular cobalamin trafficking, and mutations in CblD cause methylmalonic aciduria and/or homocystinuria. Herein, we report the first crystal structure of the globular C-terminal domain of human CblD, which is sufficient for its interaction with MMADHC (the methylmalonic aciduria and homocystinuria type C protein), or CblC, and for supporting the cytoplasmic cobalamin trafficking pathway. CblD contains an α+β fold that is structurally reminiscent of the nitro-FMN reductase superfamily. Two of the closest structural relatives of CblD are CblC, a multifunctional enzyme important for cobalamin trafficking, and the activation domain of methionine synthase. CblD, CblC, and the activation domain of methionine synthase share several distinguishing features and, together with two recently described corrinoid-dependent reductive dehalogenases, constitute a new subclass within the nitro-FMN reductase superfamily. We demonstrate that CblD enhances oxidation of cob(II)alamin bound to CblC and that disease-causing mutations in CblD impair the kinetics of this reaction. The striking structural similarity of CblD to CblC, believed to be contiguous in the cobalamin trafficking pathway, suggests the co-option of molecular mimicry as a strategy for achieving its function. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

Sex Trafficking Related Knowledge, Awareness, and Attitudes among Adolescent Female Students in Nepal: A Cross-Sectional Study.

Directory of Open Access Journals (Sweden)

Roman Shrestha

Full Text Available Sex trafficking has been a long-standing concern in Nepal. Very little has been achieved, however, in terms of actual reduction in the number of victims despite numerous anti-sex trafficking programs. This situation may be attributable to a lack of empirical evidence upon which to formulate anti-sexual trafficking interventions. This study aimed to assess sex trafficking-related knowledge, awareness and attitudes, and factors associated with sex trafficking awareness and attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns among adolescent female students in Nepal.A cross-sectional study was conducted between August-September 2013 among 292 adolescent female students (>10 years old using systematic random sampling from three high schools in Sindhupalchowk district, Nepal. As an initial step, descriptive analyses were employed to characterize the data and multivariate logistic regression analyses were used to explore factors associated with sex trafficking awareness and related attitudes.Seventy-six percent of sampled students reported that they were aware of sex trafficking and 94.6% indicated media (i.e., radio or television as the primary sources of their knowledge. Fifty-one percent mentioned relatives/friends as mediators of sex trafficking, 60.4% reported promise for better jobs as the primary attraction behind sex trafficking, and 48.6% mentioned adolescent females as the most vulnerable group for sex trafficking. Over half (56.8% of the respondents had positive attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns. Age (OR = 3.38, 95% CI:2.51-4.55, parents' occupation (OR = 3.89, 95% CI:1.58-9.58, and having a radio/TV at home (OR = 6.67, 95% CI:3.99-9.54 were significantly associated with awareness, whereas being younger (OR = 0.67, 95% CI:0.55-0.79 and having joint-family (OR = 2.67, 95% CI:1.49-4.80 were significantly associated with having a positive attitudes towards

IAEA Illicit Trafficking Database (ITDB)

Full Text Available Migration, technology, law, and measurement are each among the most topical areas of enquiry in the global human trafficking field, with much work remaining to be done in these and other areas. Beneath these particular intersections lies a crucial truth—slavery is a global business that thrives on the callous exploitation of the labor activity of a vast and highly vulnerable subclass of people whose brutalization is tacitly accepted by every participant in the global economy, from corporations to consumers. I am deeply gratified to edit Social Inclusion’s second issue on human trafficking and modern slavery. The level of scholarly interest in these topics continues to grow, and in this issue the authors explore some of the most pressing manifestations of human trafficking around the world.

Human Trafficking in Nepal: Post-Earthquake Risk and Response.

Gyawali, Bishal; Keeling, June; Kallestrup, Per

2017-04-01

As Nepal mourns the 1-year commemoration of the April 2015 earthquake and its aftershocks that killed more than 8500 people and left thousands injured and displaced, other more hidden repercussions of the resultant chaotic environment need attention: the increased risk of human trafficking. Considering that natural disasters provide a milieu for this illicit trade, there is a need for a robust response from stakeholders such as donors, civil society organizations, and government organizations against human trafficking following disasters such as the Nepal earthquake. Responsibility to prevent and fight trafficking should be explicitly included in the mandate of relief and rehabilitation mechanisms set up at the national level to coordinate the disaster relief response, serving to support populations in both rural and urban areas.

Correlates of sex trafficking in three Balkan countries

Directory of Open Access Journals (Sweden)

Athena Smith

2014-01-01

Full Text Available Trafficking of human beings has reached epidemic proportions: There are approximately 20 to 30 million slaves in the world today whereas the total value of the trade has been estimated to be around $32 billion. Albania, Bosnia-Herzegovina and Bulgaria have been particularly hit by human slavery. The author has investigated the common correlates that have facilitated the problem in these countries, such as long term poverty, passive societies, low resistance to bribery, high levels of corruption, and weak legal framework. Obstacles rising from the inability to proceed with cross-national prosecutions in combination with low sentences imposed on traffickers in both developed and developing European countries, have rendered the situation explosive. Despite the European Union’s effort to implement the new rules of the Anti-Trafficking Directive which proposes higher penalties for offenders, increased protection for victims and facilitates cross-border prosecution, only six out of the 27 EU members have fully transposed it into their national legislation.

Terrorism, Drug Trafficking, and the Globalization of Supply

Directory of Open Access Journals (Sweden)

Joel Hernández

2013-08-01

Full Text Available This case study analyzes the diversification of both terrorist groups and drug traffickers and the convergence between the two types of organizations in recent decades. As financial markets have become globalized, so have opportunities for illicit groups to transact with each other. The article builds on the collapse of Lebanese Canadian Bank in 2011 after its designation by the U.S. Treasury Department as a money-laundering financial institution tied to global drug trafficking and to Hezbollah. It follows the trajectory of two Hezbollah-associated drug kingpins: Ayman Joumaa, who facilitated trade between Hezbollah and the Zetas, and Maroun Saade, who was apprehended attempting to connect Hezbollah to the Taliban. In its analysis of the histories, motivations, and relationships among these three groups, the article reflects on relationships currently in existence between terrorist and drug-trafficking organizations, and on the implications of the possible directions these relationships might take in the future.

Although trafficked women and adolescents are at risk of unprotected or forced sex, there is little research on maternity care among trafficking survivors. We explored health care needs, service use and challenges among women who became pregnant while in the trafficking situation in the United Kingdom (UK) and clinicians' perspectives of maternity care for trafficked persons. Cross-sectional survey and qualitative interviews with trafficking survivors recruited from statutory and voluntary sector organisations in England and qualitative interviews with maternity clinicians and family doctors undertaken to offer further insight into experiences reported by these women. Twenty-eight (29%) of 98 women who took part in a large study of trafficking survivors reported one or more pregnancies while trafficked, whose data are reported here. Twelve (42.8%) of these women reported at least one termination of pregnancy while in the trafficking situation and 25 (89.3%) experienced some form of mental health disorder. Nineteen (67.9%) women experienced pre-trafficking physical abuse and 9 (32.%) sexual abuse. A quarter of women were trafficked for sexual exploitation, six for domestic servitude and two for manual labour. Survivors and clinicians described service challenges, including restrictions placed on women's movements by traffickers, poor knowledge on how to access maternity care, poor understanding of healthcare entitlements and concerns about confidentiality. Maternity care clinicians recognised potential indicators of trafficking, but considered training would help them identify and respond to victims. Main limitations include that findings reflect women who had exited the trafficking situation, however as some had only recently exited the trafficking situation, difficulties with recall were likely to be low. More than one in four women became pregnant while trafficked, indicating that maternity services offer an important contact point for identification and care

Lysosomal impairment in Parkinson's disease.

Impairment of autophagy-lysosomal pathways (ALPs) is increasingly regarded as a major pathogenic event in neurodegenerative diseases, including Parkinson's disease (PD). ALP alterations are observed in sporadic PD brains and in toxic and genetic rodent models of PD-related neurodegeneration. In addition, PD-linked mutations and post-translational modifications of α-synuclein impair its own lysosomal-mediated degradation, thereby contributing to its accumulation and aggregation. Furthermore, other PD-related genes, such as leucine-rich repeat kinase-2 (LRRK2), parkin, and phosphatase and tensin homolog (PTEN)-induced putative kinase 1 (PINK1), have been mechanistically linked to alterations in ALPs. Conversely, mutations in lysosomal-related genes, such as glucocerebrosidase (GBA) and lysosomal type 5 P-type ATPase (ATP13A2), have been linked to PD. New data offer mechanistic molecular evidence for such a connection, unraveling a causal link between lysosomal impairment, α-synuclein accumulation, and neurotoxicity. First, PD-related GBA deficiency/mutations initiate a positive feedback loop in which reduced lysosomal function leads to α-synuclein accumulation, which, in turn, further decreases lysosomal GBA activity by impairing the trafficking of GBA from the endoplasmic reticulum-Golgi to lysosomes, leading to neurodegeneration. Second, PD-related mutations/deficiency in the ATP13A2 gene lead to a general lysosomal impairment characterized by lysosomal membrane instability, impaired lysosomal acidification, decreased processing of lysosomal enzymes, reduced degradation of lysosomal substrates, and diminished clearance of autophagosomes, collectively contributing to α-synuclein accumulation and cell death. According to these new findings, primary lysosomal defects could potentially account for Lewy body formation and neurodegeneration in PD, laying the groundwork for the prospective development of new neuroprotective/disease-modifying therapeutic strategies

Fluorescent protein-based pH sensors are useful tools for measuring protein trafficking through pH changes associated with endo- and exocytosis. However, commonly used pH-sensing probes are ubiquitously expressed with their protein of interest throughout the cell, hindering our ability to focus on specific trafficking pools of proteins. We developed a family of excitation ratiometric, activatable pH responsive tandem dyes, consisting of a pH sensitive Cy3 donor linked to a fluorogenic malachite green acceptor. These cell-excluded dyes are targeted and activated upon binding to a genetically expressed fluorogen-activating protein and are suitable for selective labeling of surface proteins for analysis of endocytosis and recycling in live cells using both confocal and superresolution microscopy. Quantitative profiling of the endocytosis and recycling of tagged β2-adrenergic receptor (B2AR) at a single-vesicle level revealed differences among B2AR agonists, consistent with more detailed pharmacological profiling.

Trafficking and Syrian Refugee Smuggling: Evidence from the Balkan Route

Directory of Open Access Journals (Sweden)

Danilo Mandic

2017-06-01

Full Text Available As of March 2016, 4.8 million Syrian refugees were scattered in two dozen countries by the civil war. Refugee smuggling has been a major catalyst of human trafficking in the Middle East and Europe migrant crises. Data on the extent to which smuggling devolved into trafficking in this refugee wave is, however, scarce. This article investigates how Syrian refugees interact with smugglers, shedding light on how human smuggling and human trafficking interrelated on the Balkan Route. I rely on original evidence from in-depth interviews (n = 123 and surveys (n = 100 with Syrian refugees in Jordan, Turkey, Greece, Serbia, and Germany; as well as ethnographic observations in thirty-five refugee camps or other sites in these countries. I argue that most smugglers functioned as guides, informants, and allies in understudied ways—thus refugee perceptions diverge dramatically from government policy assumptions. I conclude with a recommendation for a targeted advice policy that would acknowledge the reality of migrant-smuggler relations, and more effectively curb trafficking instead of endangering refugees.

Debate - Trafficking as a Floating Signifier: The view from Brazil

Directory of Open Access Journals (Sweden)

Grupo Davida

2015-04-01

Full Text Available The fact that the United Nations (UN Trafficking Protocol is not an autochthonous product of the Brazilian political system has resulted in its being brought into that system as a ‘floating signifier’: something that does not point to any actual object or agreed upon meaning.[1] People who wish to criminalise prostitution have attempted to bend the Protocol in that direction while prostitutes’ rights groups have used it to critique current Brazilian laws, emphasising the need to distinguish migration for voluntary, consensual sex work from trafficking. Groups concerned with organ trafficking (a crime for which there are practically no proven cases in Brazil have managed to push their banner to the fore in the trafficking debate. Meanwhile, Brazil’s long-established and relatively successful anti-slave labour movement has been loath to ‘change their brand’, having already gained a considerable degree of institutionalisation prior to Brazil’s ratification of the Protocol in 2004.

Identifying Victims of Human Trafficking at Hotspots by Focusing on People Smuggled to Europe

Directory of Open Access Journals (Sweden)

Matilde Ventrella

2017-06-01

Full Text Available Research has shown that smuggling of migrants is associated with human trafficking. Hence, victims of human trafficking amongst smuggled migrants should be identified by EU Member States at hotspots established by the European Commission, to overcome the migrant and refugee crisis. Identified victims should be given a visa and a programme of protection to escape their traffickers. In order to achieve these objectives, research suggests that EU law on migrant smuggling should be amended and the Temporary Protection Directive should be applied to smuggled persons when there is an indication that they may be victims of human trafficking. This approach should be adopted by the EASO in cooperation with police forces investigating smuggling and trafficking at hotspots.

The trafficking of women and girls in Taiwan: characteristics of victims, perpetrators, and forms of exploitation.

Science.gov (United States)

Huang, Lanying

2017-11-09

Prior to the passing of 2009 Human Trafficking Prevention Act (HTPA), human trafficking was underestimated in Taiwan. In the past, domestic trafficking in women and girls often targeted vulnerable groups such as young girls from poor families or minority groups. Since the 1990s, an increasing flow of immigrant women, mainly from Vietnam and Indonesia and some from China, into Taiwan has created a new group of Human Trafficking victims. The current study intends to identify, describe, and categorize reported and prosecuted human trafficking cases involving women and girls according to the HTPA in Taiwan. Using the court proceedings of prosecuted trafficking in women and girls cases under Taiwan's HTPA from all 21 districts in Taiwan from 2009 to 2012 under the title keyword of 'Human Trafficking', this current study aims to categorize different patterns of existing trafficking in women and girls in Taiwan. The analysis is based on 37 court cases, involving 195 victimized women and girls and 118 perpetrators. This study identifies six forms of Human Trafficking victims according to their country of origin, vulnerability status, and means of transport. This study found that women and girls suffer from both labor and sexual exploitation, from mainly domestic male perpetrators. While sexual exploitation is more evenly distributed among citizens and immigrants and affects both adults and minors, labor exploitation seems to be an exclusive phenomenon among women immigrant workers in the data. Human Trafficking cases in Taiwan share many of the similarities of Human Trafficking in other regions, which are highly associated with gender inequality and gender-based vulnerability.

The 'dirty downside' of global sporting events: focus on human trafficking for sexual exploitation.

Science.gov (United States)

Finkel, R; Finkel, M L

2015-01-01

Human trafficking is as complex human rights and public health issue. The issue of human trafficking for sexual exploitation at large global sporting events has proven to be elusive given the clandestine nature of the industry. This piece examines the issue from a public health perspective. This is a literature review of the 'most comprehensive' studies published on the topic. A PubMed search was done using MeSH terms 'human traffickings' and 'sex trafficking' and 'human rights abuses'. Subheadings included 'statistics and numerical data', 'legislation and jurispudence', 'prevention and control', and 'therapy'. Only papers published in English were reviewed. The search showed that very few well-designed empirical studies have been conducted on the topic and only one pertinent systematic review was identified. Findings show a high prevalence of physical violence among those trafficked compared to non-trafficked women. Sexually transmitted infections and HIV AIDS are prevalent and preventive care is virtually non-existent. Quantifying human trafficking for sexual exploitation at large global sporting events has proven to be elusive given the clandestine nature of the industry. This is not to say that human trafficking for sex as well as forced sexual exploitation does not occur. It almost certainly exists, but to what extent is the big question. It is a hidden problem on a global scale in plain view with tremendous public health implications. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier Ltd.

RABA Members Act in Distinct Steps of Subcellular Trafficking of the FLAGELLIN SENSING2 Receptor[W

Cell surface proteins play critical roles in the perception of environmental stimuli at the plasma membrane (PM) and ensuing signal transduction. Intracellular localization of such proteins must be strictly regulated, which requires elaborate integration of exocytic and endocytic trafficking pathways. Subcellular localization of Arabidopsis thaliana FLAGELLIN SENSING2 (FLS2), a receptor that recognizes bacterial flagellin, also depends on membrane trafficking. However, our understanding about the mechanisms involved is still limited. In this study, we visualized ligand-induced endocytosis of FLS2 using green fluorescent protein (GFP)-tagged FLS2 expressed in Nicotiana benthamiana. Upon treatment with the flg22 peptide, internalized FLS2-GFP from the PM was transported to a compartment with properties intermediate between the trans-Golgi network (TGN) and the multivesicular endosome. This compartment gradually discarded the TGN characteristics as it continued along the trafficking pathway. We further found that FLS2 endocytosis involves distinct RABA/RAB11 subgroups at different steps. Moreover, we demonstrated that transport of de novo–synthesized FLS2 to the PM also involves a distinct RABA/RAB11 subgroup. Our results demonstrate the complex regulatory system for properly localizing FLS2 and functional differentiation in RABA members in endo- and exocytosis. PMID:23532067

The State, the family and language of 'social evils': re-stigmatising victims of trafficking in Vietnam.

Science.gov (United States)

Vijeyarasa, Ramona

2010-08-01

The Vietnamese Government continues to take steps to address trafficking in women and girls. However, rather than perceiving trafficking as a violation of human rights, greater attention is given by the government to its effects on society and social morals, particularly where victims have engaged in sex work in destination countries. Trafficked returnees are directly implicated in the State's approach to defining sex work as a 'social evil'. This approach reproduces the socio-economic inequality involved in trafficking and further marginalises trafficked women. Simultaneously, although Vietnamese women are often drawn into trafficking due to family obligations, they frequently face dishonour upon their return or are forced to hide the truth of their experience of being trafficked. This paper argues that the language of 'social evils' and the responses of the State and family undermine the ability of trafficked returnees to reintegrate. This is heightened where returnees are deemed to be transmitters of HIV infection, hence suffering human trafficking, sex-work and HIV/AIDS-related stigma. I also reflect upon whether the approach of service providers exacerbates stigma, particularly in the context of shelter rehabilitation and present several recommendations for reform, the most pressing being the need to eliminate the language of 'social evils'.

Tracking Traffickers. The IAEA Incident and Trafficking Database

International Nuclear Information System (INIS)

Webb, Greg

2013-01-01

Radioactive material is missing from a hospital. Contaminated metal is found in a scrap yard. Smugglers try to peddle nuclear- weapon-usable material. These different scenarios illustrate the risks that these materials can pose to human safety and security. To assess those risks and to develop strategies to reduce them, States must understand the implications and the scope of such incidents that are occurring around the world. To better understand and respond to these events, the IAEA maintains an Incident and Trafficking Database (ITDB) which collects information from 122 participating States and some select international organizations. They are asked to share data on a voluntary basis about incidents in which nuclear and other radioactive material has fallen ''out of regulatory control.'' This could mean reporting cases of material that has gone missing, or discoveries of material where none was expected. The cases range from the innocent misplacement of industrial radioactive sources to criminal smuggling efforts which could aid terrorist acts. This information is shared among ITDB participants, and IAEA analysts try to identify trends and characteristics that could help prevent the misuse of these potentially dangerous materials. ''The ITDB has become an internationally recognized tool for States to study the extent and nature of these incidents,'' said John Hilliard, head of the Information Management and Coordination Section that administers the database. ''We've learned a lot by studying them, and we hope the information helps us prevent accidents or crimes in the future.'' The IAEA established the database in 1995 after States became alarmed by a growing number of trafficking incidents in the early 1990s. The service was originally operated by the Department of Safeguards, but later moved to the Department of Nuclear Safety and Security, where the Office of Nuclear Security now administers all the data collection and analysis

Sex trafficking of adolescents and young adults in the United States: healthcare provider's role.

Science.gov (United States)

Chaffee, Tonya; English, Abigail

2015-10-01

Sex trafficking of adolescents and young adults is both a human rights violation and a public health problem, globally and in the United States. Healthcare providers, including obstetricians and gynecologists, interact with victims, often while they remain under their traffickers' control, but because of providers' lack of training in identification and response many victims go unrecognized and unaided. This review provides an overview of the definitions of sex trafficking and commercial sexual exploitation, contributing factors, health consequences, recruitment of victims, and identification and response by healthcare providers. The literature on definitions and risk factors associated with sex trafficking is growing; however, literature on healthcare providers' role in addressing sex trafficking remains more limited. It is increasingly recognized that healthcare providers have an important role in victim identification and response and as advocates, collaborating with national, regional, and local agencies to increase awareness of sex trafficking as a public health problem and to address the needs of adolescent and young adult victims and survivors globally and in the United States. As professionals who interact with adolescent and young adult victims of sex trafficking, healthcare providers have an important role: in collaboration with other professionals and agencies they can help to identify, respond to, extricate, protect, and advocate for victims and survivors.

People for sale: the need for a multidisciplinary approach towards human trafficking.

Van Impe, K

2000-01-01

The article addresses the question of how to develop appropriate measures to tackle trafficking in women, based on the findings of a study of trafficking between the Philippines and Belgium. It argues that there is no easy or unidimensional solution to human trafficking, since it is influenced by a complex set of factors, often working in combination with one another. It concludes that control measures alone cannot stop the flow of trafficking in women and that a legal approach which relies solely on one type of legislation would be too narrow. An effective strategy must combine and balance punitive measures with protection of human rights, stricter border control and the removal of the root causes of irregular movements. Measures must be agreed and coordinated between origin, transit and receiving countries.

In an effort to combat human trafficking in the district, the local authorities launched

The IAEA's Illicit Trafficking Database Programme

Full text: As part of its overall programme on nuclear material security, the IAEA has since 1995 maintained a database of incidents of trafficking in nuclear materials and other radioactive sources. The Illicit Trafficking Database Programme (ITDP) is intended to assist Member States by alerting them to current incidents, by facilitating exchange of reliable, detailed information about incidents, and by identifying any common threads or trends that might assist States in combating illicit trafficking. The ITDP also seeks to better inform the public by providing basic information to the media concerning illicit trafficking events. Approximately 70 States have joined this programme for collecting and sharing information on trafficking incidents. Reporting States have the opportunity to designate what information may be shared with other States and what may be shared with the public. In cases where the IAEA's first information about a possible incident comes from news media or other open sources rather than from a State notification, the information first is evaluated, and then, if warranted, the relevant State or States are contacted to request confirmation or clarification of an alleged incident. During 2000, as a result of experience gained working with information on illicit nuclear trafficking, the IAEA developed of a flexible and comprehensive new database system. The new system has an open architecture that accommodates structured information from States, in-house information, open-source articles, and other information sources, such as pictures, maps and web links. The graphical user interface allows data entry, maintenance and standard and ad-hoc reporting. The system also is linked to a Web-based query engine, which enables searching of both structured and open-source information. For the period 1 January 1993 through 31 March 2001, the database recorded more than 550 incidents, of which about two-thirds have been confirmed by States. (Some of these

Summary How mutant prion protein (PrP) leads to neurological dysfunction in genetic prion diseases is unknown. Tg(PG14) mice synthesize a misfolded mutant PrP which is partially retained in the neuronal endoplasmic reticulum (ER). As these mice age, they develop ataxia and massive degeneration of cerebellar granule neurons (CGNs). Here, we report that motor behavioral deficits in Tg(PG14) mice emerge before neurodegeneration and are associated with defective glutamate exocytosis from granule neurons due to impaired calcium dynamics. We found that mutant PrP interacts with the voltage-gated calcium channel α2δ-1 subunit, which promotes the anterograde trafficking of the channel. Owing to ER retention of mutant PrP, α2δ-1 accumulates intracellularly, impairing delivery of the channel complex to the cell surface. Thus, mutant PrP disrupts cerebellar glutamatergic neurotransmission by reducing the number of functional channels in CGNs. These results link intracellular PrP retention to synaptic dysfunction, indicating new modalities of neurotoxicity and potential therapeutic strategies. PMID:22542184

To investigate physical and mental health and experiences of violence among male and female trafficking survivors in a high-income country. Our data were derived from a cross-sectional survey of 150 men and women in England who were in contact with posttrafficking support services. Interviews took place over 18 months, from June 2013 to December 2014. Participants had been trafficked for sexual exploitation (29%), domestic servitude (29.3%), and labor exploitation (40.4%). Sixty-six percent of women reported forced sex during trafficking, including 95% of those trafficked for sexual exploitation and 54% of those trafficked for domestic servitude. Twenty-one percent of men and 24% of women reported ongoing injuries, and 8% of men and 23% of women reported diagnosed sexually transmitted infections. Finally, 78% of women and 40% of men reported high levels of depression, anxiety, or posttraumatic stress disorder symptoms. Psychological interventions to support the recovery of this highly vulnerable population are urgently needed.

Despite the multiple physical and psychological health consequences associated with human trafficking, there is little evidence-based guidance available for health providers on assessing and meeting the health needs of trafficked people. We aimed to review literature that provided guidance or research on care provision for people who had been trafficked. We conducted a systematic review and qualitative analysis of peer-reviewed and grey literature. Data sources included electronic databases, reference list screening, citation tracking, and expert recommendations. Documents were included if they reported on: 1) male or females (adults or children) who were currently or had previously been trafficked; 2) health interventions or service provision; 3) primary, secondary, tertiary or specialist post-trafficking services; and 4) World Bank high income countries. Two reviewers independently screened and quality appraised documents. Framework analysis was used to analyse extracted data. Forty-four documents were included, 19 of which reported findings of primary studies and nine of which exclusively addressed children. Evidence to inform the identification, referral and care of trafficked people is extremely limited. Within current literature on survivor identification, key indicators included signs of physical and sexual abuse, absence of documentation, and being accompanied by a controlling companion. Findings highlighted the importance of interviewing possible victims in private, using professional interpreters, and building trust. For provision of care, key themes included the importance of comprehensive needs assessments, adhering to principles of trauma-informed care, and cultural sensitivity. Further prominent themes were the necessity of multi-agency working strategies and well-defined referral pathways. Human trafficking survivors require healthcare that is trauma-informed and culturally sensitive to their particular needs. Coordination is needed between health

Previous studies have found a high prevalence of depression and post-traumatic stress disorder (PTSD) among survivors of human trafficking. European countries are required to assist trafficked people in their psychological recovery, but there are no rigorous data on the costs of doing so. The objectives of this study were to quantify the use of secondary mental health services by survivors of human trafficking; to estimate the cost of survivors' use of secondary mental health services provided by the UK National Health Service (NHS); and to identify factors that predict higher costs of mental health service provision. Historical cohort study of psychiatric patients who had experienced human trafficking. The South London and Maudsley NHS Trust (SLaM) Biomedical Research Centre Case Register Interactive Search (CRIS) database was used to identify anonymised full patient records of patients who had experienced human trafficking and who had accessed SLaM mental health services between 2007 and 2012. Data were extracted on socio-demographic and trafficking characteristics and contacts with mental health services. Total costs were calculated by multiplying each resource use item by an appropriate unit cost. Factors that predicted high mental health service costs were analysed using regression models. One hundred nineteen patients were included in the analysis. Mean total mental health service costs per patient were £27,293 (sd 80,985) and mean duration of contact with services was 1490 (sd 757) days (approximately 4 years). Regression analysis showed that higher costs were associated with diagnosis of psychotic disorder (p trafficking violence (p = 0.06). Patients diagnosed with psychotic disorders cost approximately £32,635 more than patients with non-psychotic disorders/psychological distress but no formal diagnosis and patients whose clinical notes documented pre-trafficking violence cost £88,633 more than patients for whom pre-trafficking violence was not

Physician Encounters with Human Trafficking: Legal Consequences and Ethical Considerations.

2017-01-01

There is growing recognition and evidence that health care professionals regularly encounter-though they may not identify-victims of human trafficking in a variety of health care settings. Identifying and responding appropriately to trafficking victims or survivors requires not only training in trauma-informed care but also consideration of the legal and ethical issues that arise when serving this vulnerable population. This essay examines three areas of law that are relevant to this case scenario: criminal law, with a focus on conspiracy; service provider regulations, with a focus on mandatory reporting laws; and human rights law. In addition to imposing a legal mandate, the law can inform ethical considerations about how health care professionals should respond to human trafficking. © 2017 American Medical Association.

The human M(3) muscarinic acetylcholine receptor is present in both the central and peripheral nervous system, and it is involved in the pathophysiology of several neurodegenerative and autoimmune diseases. We suggested a possible N-glycosylation map for the M(3) muscarinic receptor expressed in COS-7 cells. Here, we examined the role that N-linked glycans play in the folding and in the cell surface trafficking of this receptor. The five potential asparagine-linked glycosylation sites in the muscarinic receptor were mutated and transiently expressed in COS-7 cells. The elimination of N-glycan attachment sites did not affect the cellular expression levels of the receptor. However, proper receptor localization to the plasma membrane was affected as suggested by reduced [(3)H]-N-methylscopolamine binding. Confocal microscopy confirmed this observation and showed that the nonglycosylated receptor was primarily localized in the intracellular compartments. The mutant variant showed an increase in phosphorylation of the α-subunit of eukaryote initiation factor 2, and other well-known endoplasmic reticulum stress markers of the unfolded protein response pathway, which further supports the proposal of the improper intracellular accumulation of the nonglycosylated receptor. The receptor devoid of glycans showed more susceptibility to events that culminate in apoptosis reducing cell viability. Our findings suggest up-regulation of pro-apoptotic Bax protein, down-regulation of anti-apoptotic Bcl-2, and cleavage of caspase-3 effectors. Collectively, our data provide experimental evidence of the critical role that N-glycan chains play in determining muscarinic receptor distribution, localization, as well as cell integrity. © The Author 2011.

Synaptotagmins regulate vesicle trafficking and fusion of vesicles with membranes - processes that have been implicated in cell migration. We therefore hypothesized that synaptotagmins play a role in T-cell migration. Amongst synaptotagmins 1-11, we found synaptotagmin 3 (SYT3) to be the only one that is expressed in T cells. CXCR4-triggered migration was inhibited by antisense synaptotagmin 3 mRNA and by the isolated C2B domain, known to impair oligomerization of all synaptotagmins, but not by a C2B mutant that binds Ca(2+) but does not block oligomerization. The C2B domain also blocked CXCR4-triggered actin polymerization and invasion. However, CXCR4-dependent adhesion in flow was not affected. Surprisingly, we found that little or no SYT3 is present near the plasma membrane but that it is mainly localized in multivesicular bodies, which also contained much of the CXCR4. Impaired SYT3 function blocked CXCR4 recycling and thus led to reduced surface levels of CXCR4. Migration was restored by overexpression of CXCR4. We conclude that STT3 is essential for CXCR4 recycling in T cells and thereby for the maintenance of high CXCR4 surface levels required for migration.

Little is known about the relationship between illegal firms and local economic activity. In this paper I study changes in satellite night lights across Mexican municipalities after the arrival of large drug trafficking organizations in the period 2000-2010. After accounting for state trends and differences in political regimes, results indicate no significant change in night lights after the arrival of these illegal firms. Estimated coefficients are precise, robust, and similar across different drug trafficking organizations.

Nurses' Perceptions of Victims of Human Trafficking in an Urban Emergency Department: A Qualitative Study.

Science.gov (United States)

Long, Elizabeth; Dowdell, Elizabeth B

2017-12-15

Human trafficking is estimated to surpass the drug trade as the leading illegal industry in the world. According to a recent study, over 87.8% of trafficking survivors came into contact with a healthcare professional while they were enslaved and were not identified as a victim of human trafficking. The aims of this study are to understand the perceptions of emergency nurses about human trafficking, victims of violence, and prostitution. A qualitative, descriptive study using a semi-structured interview approach was done with ten registered nurses in a large, urban Emergency Department in the northeastern U.S. Interviews were recorded and transcribed; thematic analysis was performed. Six themes emerged from the interviews including, "human trafficking exists in the patient population" yet no nurse has screened or treated a victim; human trafficking victims are perceived to be "young, female, and foreign born"; all of the emergency nurses reported having worked with or screened a victim of violence; victims of violence were viewed as patients who present as "sad and grieving"; prostitutes are seen as "hard and tough"; and emergency nurses did not have education on human trafficking victims' needs or resources. Emergency nurses should be more aware about victims of human trafficking. The media portrayal of human trafficking victims had influenced the nurses' perceptions of this population. Victims of violence are perceived to be very different from prostitutes, but there is a desire for education about violence as well as information about specific resources open to victims.

Lutya, Thozama Mandisa

2010-12-01

The United Nations estimates that 79% of teenage girls trafficked globally every year are forced into involuntary prostitution. About 247 000 South African children work in exploitative conditions; about 40 000 South African female teenagers work as prostitutes. This paper investigates lifestyles and routine activities of teenagers at risk of being trafficked for involuntary prostitution. The key concepts involuntary prostitution, intergenerational sex and exploitative conditions are defined in relation to the lifestyles and routine activities of South African female teenagers. Human trafficking for involuntary prostitution is described, based on a literature review. Lifestyle exposure and routine activities theories help to explain the potential victimisation of these teenagers in human trafficking for involuntary prostitution. Actual lifestyle and routine activities of South African teenagers and risky behaviours (substance abuse, intergenerational sex and child prostitution) are discussed as factors that make teens vulnerable to such trafficking. This paper recommends that human trafficking prevention efforts (awareness programmes and information campaigns) be directed at places frequented by human traffickers and teenagers in the absence of a capable guardian to reduce victimisation, as traffickers analyse the lifestyles and routine activities of their targets. South Africa should also interrogate entrenched practices such as intergenerational sex.

Phosphorylation-dependent trafficking of plasma membrane proteins in animal and plant cells.

Science.gov (United States)

Offringa, Remko; Huang, Fang

2013-09-01

In both unicellular and multicellular organisms, transmembrane (TM) proteins are sorted to and retained at specific membrane domains by endomembrane trafficking mechanisms that recognize sorting signals in the these proteins. The trafficking and distribution of plasma membrane (PM)-localized TM proteins (PM proteins), especially of those PM proteins that show an asymmetric distribution over the PM, has received much attention, as their proper PM localization is crucial for elementary signaling and transport processes, and defects in their localization often lead to severe disease symptoms or developmental defects. The subcellular localization of PM proteins is dynamically regulated by post-translational modifications, such as phosphorylation and ubiquitination. These modificaitons mostly occur on sorting signals that are located in the larger cytosolic domains of the cargo proteins. Here we review the effects of phosphorylation of PM proteins on their trafficking, and present the key examples from the animal field that have been subject to studies for already several decades, such as that of aquaporin 2 and the epidermal growth factor receptor. Our knowledge on cargo trafficking in plants is largely based on studies of the family of PIN FORMED (PIN) carriers that mediate the efflux of the plant hormone auxin. We will review what is known on the subcellular distribution and trafficking of PIN proteins, with a focus on how this is modulated by phosphorylation, and identify and discuss analogies and differences in trafficking with the well-studied animal examples. © 2013 Institute of Botany, Chinese Academy of Sciences.

Who’s Who at the Border? A rights-based approach to identifying human trafficking at international borders

Directory of Open Access Journals (Sweden)

Marika McAdam

2013-09-01

Full Text Available International borders are widely touted as bastions in the fight against trafficking in persons. This article acknowledges the important role border officials play in preventing human trafficking, but calls for expectations to be tempered by deference to the conceptual complexity of cross-border trafficking and the migration processes involved. The fact that many trafficked victims begin their journeys as irregular or smuggled migrants highlights the challenge posed to border officials in identifying trafficked persons among the people they encounter. Indicators of trafficking generally relate to the exploitation phase, leaving border officials with little guidance as to how persons vulnerable to trafficking can be accurately identified before any exploitation has occurred. Ultimately, this paper advocates a pragmatic rights-based approach in designating anti-trafficking functions to border officials. A rights-based approach to border control acknowledges the core work of border officials as being to uphold border integrity, while ensuring that their performance of this role does not jeopardise the rights of those they intercept nor result in missed opportunities for specialists to identify trafficked persons and other vulnerable people among them.

The Prominent Role of National Judges in Interpreting the International Definition of Human Trafficking

Directory of Open Access Journals (Sweden)

Luuk B Esser

2016-05-01

Full Text Available Although there has been much discussion of the scope of the concept of human trafficking in international literature, the part played by national courts in interpreting definitions based on the international definition of human trafficking in the UN Trafficking Protocol has received little attention. When a judge interprets an offence, he or she clarifies or adds new meaning to it. The space for this is even greater when the underlying definition is broadly formulated, as in the case of the international definition of human trafficking. This article demonstrates that, although this international definition establishes the outer parameters within which conduct must be made a criminal offence, domestic courts still have room to flesh out the definition in national contexts. The role of national judges needs more consideration in today’s discourse on the legal definition of human trafficking.

Houston-Kolnik, Jaclyn D; Soibatian, Christina; Shattell, Mona M

2017-02-01

The present qualitative study explores advocates' opinions of misinformation about human trafficking in the media and describes advocates' strategies to counter the misinformation presented by the media. Thus, 15 advocates who work against human trafficking in Chicago-based nonprofit organizations participated in semistructured interviews about their opinions and strategies. Data were analyzed using thematic content analysis. The present study identifies specific misperceptions of human trafficking in the media, highlights advocates' opinions of this misinformation, and discusses advocates' strategies to counteract inaccurate media, adding support to the role of media advocacy. Advocates note how media images shape and perpetuate stereotypes of trafficking through glamorizing sex work and sensationalizing stories that are most often international depictions of trafficking. Advocates report media generally shares only a piece of the story, simplifying the stories of survivors and the issue of human trafficking. Advocates critique media perpetuating these misperceptions for how they may contribute to policies and programs which fail to address structural factors that create vulnerabilities to be trafficked and the multisystem needs of survivors. However, advocates also note misperceptions can be counteracted by producing sensitive, informed media through social platforms. Advocates share their strategies counteracting misinformation through engaging in informative conversations, utilizing social media to educate, and promoting media messages of survivor agency. Research, clinical, and policy implications are also discussed. The present study emphasizes the importance of decision makers and service providers being critical consumers of media and to assess how media portrayals may (or may not) inform their understanding and response to the issue.

Real-time visualization of HIV-1 GAG trafficking in infected macrophages.

Directory of Open Access Journals (Sweden)

Karine Gousset

2008-03-01

Full Text Available HIV-1 particle production is driven by the Gag precursor protein Pr55(Gag. Despite significant progress in defining both the viral and cellular determinants of HIV-1 assembly and release, the trafficking pathway used by Gag to reach its site of assembly in the infected cell remains to be elucidated. The Gag trafficking itinerary in primary monocyte-derived macrophages is especially poorly understood. To define the site of assembly and characterize the Gag trafficking pathway in this physiologically relevant cell type, we have made use of the biarsenical-tetracysteine system. A small tetracysteine tag was introduced near the C-terminus of the matrix domain of Gag. The insertion of the tag at this position did not interfere with Gag trafficking, virus assembly or release, particle infectivity, or the kinetics of virus replication. By using this in vivo detection system to visualize Gag trafficking in living macrophages, Gag was observed to accumulate both at the plasma membrane and in an apparently internal compartment that bears markers characteristic of late endosomes or multivesicular bodies. Significantly, the internal Gag rapidly translocated to the junction between the infected macrophages and uninfected T cells following macrophage/T-cell synapse formation. These data indicate that a population of Gag in infected macrophages remains sequestered internally and is presented to uninfected target cells at a virological synapse.

We have developed a suitable heterologous cell expression system to study the localization, trafficking, and site(s) of function of the human ABCG1 transporter. Increased plasma membrane (PM) and late endosomal (LE) cholesterol generated by ABCG1 was removed by lipoproteins and liposomes, but not apoA-I. Delivery of ABCG1 to the PM and LE was required for ABCG1-mediated cellular cholesterol efflux. ABCG1 LEs frequently contacted the PM, providing a collisional mechanism for transfer of ABCG1-mobilized cholesterol, similar to ABCG1-mediated PM cholesterol efflux to lipoproteins. ABCG1-mobilized LE cholesterol also trafficked to the PM by a non-vesicular pathway. Transfer of ABCG1-mobilized cholesterol from the cytoplasmic face of LEs to the PM and concomitant removal of cholesterol from the outer leaflet of the PM bilayer by extracellular acceptors suggests that ABCG1 mobilizes cholesterol on both sides of the lipid bilayer for removal by acceptors. ABCG1 increased uptake of HDL into LEs, consistent with a potential ABCG1-mediated cholesterol efflux pathway involving HDL resecretion. Thus, ABCG1 at the PM mobilizes PM cholesterol and ABCG1 in LE/LYS generates mobile pools of cholesterol that can traffic by both vesicular and non-vesicular pathways to the PM where it can also be transferred to extracellular acceptors with a lipid surface.

Full Text Available Inappropriate surface expression of voltage-gated Ca(2+channels (CaV in pancreatic ß-cells may contribute to the development of type 2 diabetes. First, failure to increase intracellular Ca(2+ concentrations at the sites of exocytosis impedes insulin release. Furthermore, excessive Ca(2+ influx may trigger cytotoxic effects. The regulation of surface expression of CaV channels in the pancreatic β-cells remains unknown. Here, we used real-time 3D confocal and TIRFM imaging, immunocytochemistry, cellular fractionation, immunoprecipitation and electrophysiology to study trafficking of L-type CaV1.2 channels upon β-cell stimulation. We found decreased surface expression of CaV1.2 and a corresponding reduction in L-type whole-cell Ca(2+ currents in insulin-secreting INS-1 832/13 cells upon protracted (15-30 min stimulation. This internalization occurs by clathrin-dependent endocytosis and could be prevented by microtubule or dynamin inhibitors. eIF3e (Eukaryotic translation initiation factor 3 subunit E is part of the protein translation initiation complex, but its effect on translation are modest and effects in ion channel trafficking have been suggested. The factor interacted with CaV1.2 and regulated CaV1.2 traffic bidirectionally. eIF3e silencing impaired CaV1.2 internalization, which resulted in an increased intracellular Ca(2+ load upon stimulation. These findings provide a mechanism for regulation of L-type CaV channel surface expression with consequences for β-cell calcium homeostasis, which will affect pancreatic β-cell function and insulin production.

Surface proteins are important for the fitness and virulence of the Gram-positive pathogen Streptococcus pneumoniae. They are crucial for interaction of the pathogen with its human host during infection. Therefore, the analysis of the pneumococcal surface proteome is an important task that requires powerful tools. In this study, two different methods, an optimized biotinylation approach and shaving with trypsin beads, were applied to study the pneumococcal surface proteome and to identify surface-exposed protein domains, respectively. The identification of nearly 95% of the predicted lipoproteins and 75% of the predicted sortase substrates reflects the high coverage of the two classical surface protein classes accomplished in this study. Furthermore, the biotinylation approach was applied to study the impact of an impaired lipoprotein maturation pathway on the cell envelope proteome and exoproteome. Loss of the lipoprotein diacylglyceryl transferase Lgt leads to striking changes in the lipoprotein distribution. Many lipoproteins disappear from the surface proteome and accumulate in the exoproteome. Further insights into lipoprotein processing in pneumococci are provided by immunoblot analyses of bacterial lysates and corresponding supernatant fractions. Taken together, the first comprehensive overview of the pneumococcal surface and exoproteome is presented, and a model for lipoprotein processing in S. pneumoniae is proposed.

Child trafficking and commercial sexual exploitation: a review of promising prevention policies and programs.

Science.gov (United States)

Rafferty, Yvonne

2013-10-01

Child trafficking, including commercial sexual exploitation (CSE), is one of the fastest growing and most lucrative criminal activities in the world. The global enslavement of children affects countless numbers of victims who are trafficked within their home countries or transported away from their homes and treated as commodities to be bought, sold, and resold for labor or sexual exploitation. All over the world, girls are particularly likely to be trafficked into the sex trade: Girls and women constitute 98% of those who are trafficked for CSE. Health and safety standards in exploitative settings are generally extremely low, and the degree of experienced violence has been linked with adverse physical, psychological, and social-emotional development. The human-rights-based approach to child trafficking provides a comprehensive conceptual framework whereby victim-focused and law enforcement responses can be developed, implemented, and evaluated. This article highlights promising policies and programs designed to prevent child trafficking and CSE by combating demand for sex with children, reducing supply, and strengthening communities. The literature reviewed includes academic publications as well as international and governmental and nongovernmental reports. Implications for social policy and future research are presented. © 2013 American Orthopsychiatric Association.

Roles of membrane trafficking in plant cell wall dynamics

Directory of Open Access Journals (Sweden)

Kazuo eEbine

2015-10-01

Full Text Available The cell wall is one of the characteristic components of plant cells. The cell wall composition differs among cell types and is modified in response to various environmental conditions. To properly generate and modify the cell wall, many proteins are transported to the plasma membrane or extracellular space through membrane trafficking, which is one of the key protein transport mechanisms in eukaryotic cells. Given the diverse composition and functions of the cell wall in plants, the transport of the cell wall components and proteins that are involved in cell wall-related events could be specialized for each cell type, i.e., the machinery for cell wall biogenesis, modification, and maintenance could be transported via different trafficking pathways. In this review, we summarize the recent progress in the current understanding of the roles and mechanisms of membrane trafficking in plant cells and focus on the biogenesis and regulation of the cell wall.

Life after Trafficking in Azerbaijan: Reintegration experiences of survivors

2018-04-01

Full Text Available Assisting survivors of trafficking is considered one of the pillars of a human rights-based response Shelter, medical, psychological and legal assistance in the short term and job placement, accommodation and reunification with family and community in the long term are critical steps for helping them recover and feel in control of their lives and futures. This paper examines survivors’ experiences of trafficking and recovery in the Azerbaijani context, using questionnaire responses from 22 women who were trafficked for sexual exploitation between 2006 and 2009 and who were assisted upon their return. It finds that while Azerbaijan has been quite successful at short-term assistance, there are still significant gaps in longer-term assistance, especially with regard to job placement and family reunification. Survivors point to these gaps as significant impediments to full reintegration into society. Looking at their experiences can provide insights into improvements in assistance programmes that can be implemented in both Azerbaijan and elsewhere.

A Formidable Task: Reflections on obtaining legal empirical evidence on human trafficking in Canada

Directory of Open Access Journals (Sweden)

Hayli Millar

2017-04-01

Full Text Available This article explores the experiences, challenges and findings of two empirical research studies examining Canada’s legal efforts to combat human trafficking. The authors outline the methodologies of their respective studies and reflect on some of the difficulties they faced in obtaining empirical data on human trafficking court cases and legal proceedings. Ultimately, the authors found that Canadian trafficking case law developments are in their early stages with very few convictions, despite a growing number of police-reported charges. The authors assert it is difficult to assess the efficacy and effects of Canadian anti-trafficking laws and policies due to the institutional and political limitations to collecting legal data in this highly politicised subject area. They conclude with five recommendations to increase the transparency of Canada’s public claims about its anti-trafficking enforcement efforts and call for more empirically-based law reform.

Measures Against-Illicit Trafficking of Nuclear Materials and Other Radioactive Sources

International Nuclear Information System (INIS)

Barakat, M.B.; Nassef, M.H.; El Mongy, S.A.

2008-01-01

Since the early nineties, illicit trafficking (IT) of nuclear materials and radioactive sources appeared as a new trend which raised the concern of the international community due to the grave consequences that would merge if these materials or radioactive sources fell into the hands of terrorist groups. However, by the end of the last century illicit trafficking of nuclear materials and radioactive sources lost its considerable salience, in spite of seizure of considerable amounts of 2 '3'5U (76% enrichment) in Bulgaria (May 1999) and also 235 U (30% enrichment) in Georgia (April 2000). Nevertheless, IT should be always considered as a continued and viable threat to the international community. Awareness of the problem should be developed and maintained among concerned circles as the first step towards combating illicit trafficking of nuclear materials and radioactive sources. Illicit trafficking of nuclear and radioactive materials needs serious consideration and proper attention by the governmental law enforcement authorities. Measures to combat with IT of nuclear material or radioactive sources should be effective in recovery, of stolen, removed or lost nuclear materials or radioactive sources due to the failure of the physical protection system or the State System Accounting and Control (SSAC) system which are normally applied for protecting these materials against illegal actions. Measures such as use of modern and efficient radiation monitoring equipment at the borders inspection points, is an important step in preventing the illicit trafficking of nuclear and radioactive materials across the borders. Also providing radiological training to specific personnel and workers in this field will minimize the consequences of a radiological attack in case of its occurrence. There is a real need to start to enter into cooperative agreements to strengthen borders security under the umbrella of IAEA to faster as an international cooperation in the illicit trafficking

Beck, Dana C; Choi, Kristen R; Munro-Kramer, Michelle L; Lori, Jody R

2017-12-01

The purpose of this review is to integrate evidence on human trafficking in Ethiopia and identify gaps and recommendations for service delivery, research and training, and policy. A scoping literature review approach was used to systematically search nursing, medical, psychological, law, and international databases and synthesize information on a complex, understudied topic. The search yielded 826 articles, and 39 met the predetermined criteria for inclusion in the review. Trafficking in Ethiopia has occurred internally and externally in the form of adult and child labor and sex trafficking. There were also some reports of organ trafficking and other closely related human rights violations, such as child marriage, child soldiering, and exploitative intercountry adoption. Risk factors for trafficking included push factors (poverty, political instability, economic problems, and gender discrimination) and pull factors (demand for cheap labor). Trafficking was associated with poor health and economic outcomes for victims. Key recommendations for service delivery, research and training, and policy are identified, including establishing comprehensive services for survivor rehabilitation and reintegration, conducting quantitative health outcomes research, and reforming policy around migration and trafficking. Implementing the recommendations identified by this review will allow policy makers, researchers, and practitioners to take meaningful steps toward confronting human trafficking in Ethiopia.

Methods of analysis of the membrane trafficking pathway from recycling endosomes to lysosomes.

Science.gov (United States)

Matsui, Takahide; Fukuda, Mitsunori

2014-01-01

The transferrin receptor (TfR) is responsible for iron uptake through its trafficking between the plasma membrane and recycling endosomes, and as a result it has become a well-known marker for recycling endosomes. Although the molecular basis of the TfR recycling pathway has been thoroughly investigated, the TfR degradation mechanism has been poorly understood. Exposure of cultured cells to two drugs, the protein synthesis inhibitor cycloheximide and the V-ATPase inhibitor bafilomycin A1, recently showed that TfR is not only recycled back to the plasma membrane after endocytosis but is constitutively transported to lysosomes for degradation. The results of genome-wide screening of mouse Rab small GTPases (common regulators of membrane trafficking in all eukaryotes) have indicated that Rab12 regulates TfR trafficking to lysosomes independently of the known membrane trafficking pathways, for example, the conventional endocytic pathway and recycling pathway. This chapter summarizes the methods that the authors used to analyze the membrane trafficking pathway from recycling endosomes to lysosomes that is specifically regulated by Rab12. © 2014 Elsevier Inc.

Anterograde trafficking of KCa3.1 in polarized epithelia is Rab1- and Rab8-dependent and recycling endosome-independent.

Directory of Open Access Journals (Sweden)

Claudia A Bertuccio

Full Text Available The intermediate conductance, Ca2+-activated K+ channel (KCa3.1 targets to the basolateral (BL membrane in polarized epithelia where it plays a key role in transepithelial ion transport. However, there are no studies defining the anterograde and retrograde trafficking of KCa3.1 in polarized epithelia. Herein, we utilize Biotin Ligase Acceptor Peptide (BLAP-tagged KCa3.1 to address these trafficking steps in polarized epithelia, using MDCK, Caco-2 and FRT cells. We demonstrate that KCa3.1 is exclusively targeted to the BL membrane in these cells when grown on filter supports. Following endocytosis, KCa3.1 degradation is prevented by inhibition of lysosomal/proteosomal pathways. Further, the ubiquitylation of KCa3.1 is increased following endocytosis from the BL membrane and PR-619, a deubiquitylase inhibitor, prevents degradation, indicating KCa3.1 is targeted for degradation by ubiquitylation. We demonstrate that KCa3.1 is targeted to the BL membrane in polarized LLC-PK1 cells which lack the μ1B subunit of the AP-1 complex, indicating BL targeting of KCa3.1 is independent of μ1B. As Rabs 1, 2, 6 and 8 play roles in ER/Golgi exit and trafficking of proteins to the BL membrane, we evaluated the role of these Rabs in the trafficking of KCa3.1. In the presence of dominant negative Rab1 or Rab8, KCa3.1 cell surface expression was significantly reduced, whereas Rabs 2 and 6 had no effect. We also co-immunoprecipitated KCa3.1 with both Rab1 and Rab8. These results suggest these Rabs are necessary for the anterograde trafficking of KCa3.1. Finally, we determined whether KCa3.1 traffics directly to the BL membrane or through recycling endosomes in MDCK cells. For these studies, we used either recycling endosome ablation or dominant negative RME-1 constructs and determined that KCa3.1 is trafficked directly to the BL membrane rather than via recycling endosomes. These results are the first to describe the anterograde and retrograde trafficking of KCa3

Egyud, Amber; Stephens, Kimberly; Swanson-Bierman, Brenda; DiCuccio, Marge; Whiteman, Kimberly

2017-11-01

Health care professionals have not been successful in recognizing or rescuing victims of human trafficking. The purpose of this project was to implement a screening system and treatment algorithm in the emergency department to improve the identification and rescue of victims of human trafficking. The lack of recognition by health care professionals is related to inadequate education and training tools and confusion with other forms of violence such as trauma and sexual assault. A multidisciplinary team was formed to assess the evidence related to human trafficking and make recommendations for practice. After receiving education, staff completed a survey about knowledge gained from the training. An algorithm for identification and treatment of sex trafficking victims was implemented and included a 2-pronged identification approach: (1) medical red flags created by a risk-assessment tool embedded in the electronic health record and (2) a silent notification process. Outcome measures were the number of victims who were identified either by the medical red flags or by silent notification and were offered and accepted intervention. Survey results indicated that 75% of participants reported that the education improved their competence level. The results demonstrated that an education and treatment algorithm may be an effective strategy to improve recognition. One patient was identified as an actual victim of human trafficking; the remaining patients reported other forms of abuse. Education and a treatment algorithm were effective strategies to improve recognition and rescue of human trafficking victims and increase identification of other forms of abuse.

Medical tourism and organ trafficking

Directory of Open Access Journals (Sweden)

Athena Smith

2012-01-01

Full Text Available The growth of medical tourism in developing nations has not only helped the local economies but also has assisted patients from the developed world to seek treatment at a lower cost. However, the expansion of the sector has been stigmatized by the growth of organ trafficking that facilitates organ transplantation to those who can afford it. Although developing countries have been taking measures to prohibit the sale of organs, the large gap between demand and supply has fuelled a black market that involves the "brokers", the medical personnel and the poor whose abuse and exploitation is fuelled by the expansion of the sector and the illegitimate opportunities it creates on the side. The problem is exacerbated by the low supply in developed countries, where living potential donors appear to be misinformed about the process and hesitate to register as donors. The need for a nationwide campaign of awareness is urgently needed as the expansion of medical tourism has the potential of encouraging a further rise in organ trafficking.

Untold stories: biases and selection effects in research with victims of trafficking for sexual exploitation.

Science.gov (United States)

Brunovskis, Anette; Surtees, Rebecca

2010-01-01

Recent discussions of trafficking research have included calls for more innovative studies and new methodologies in order to move beyond the current trafficking narrative, which is often based on unrepresentative samples and overly simplified images. While new methods can potentially play a role in expanding the knowledge base on trafficking, this article argues that the solution is not entirely about applying new methods, but as much about using current methods to greater effect and with careful attention to their limitations and ethical constraints. Drawing on the authors' experience in researching trafficking issues in a number of projects over the past decade, the article outlines and exemplifies some of the methodological and ethical issues to be considered and accommodated when conducting research with trafficked persons -- including unrepresentative samples; access to respondents; selection biases by "gatekeepers" and self selection by potential respondents. Such considerations should inform not only how research is undertaken but also how this information is read and understood. Moreover, many of these considerations equally apply when considering the application of new methods within this field. The article maintains that a better understanding of how these issues come into play and inform trafficking research will translate into tools for conducting improved research in this field and, by implication, new perspectives on human trafficking.

Drosophila VAMP7 regulates Wingless intracellular trafficking.

Science.gov (United States)

Gao, Han; He, Fang; Lin, Xinhua; Wu, Yihui

2017-01-01

Drosophila Wingless (Wg) is a morphogen that determines cell fate during development. Previous studies have shown that endocytic pathways regulate Wg trafficking and signaling. Here, we showed that loss of vamp7, a gene required for vesicle fusion, dramatically increased Wg levels and decreased Wg signaling. Interestingly, we found that levels of Dally-like (Dlp), a glypican that can interact with Wg to suppress Wg signaling at the dorsoventral boundary of the Drosophila wing, were also increased in vamp7 mutant cells. Moreover, Wg puncta in Rab4-dependent recycling endosomes were Dlp positive. We hypothesize that VAMP7 is required for Wg intracellular trafficking and the accumulation of Wg in Rab4-dependent recycling endosomes might affect Wg signaling.

Munc13-4 Is a Rab11-binding Protein That Regulates Rab11-positive Vesicle Trafficking and Docking at the Plasma Membrane.

The small GTPase Rab11 and its effectors control trafficking of recycling endosomes, receptor replenishment and the up-regulation of adhesion and adaptor molecules at the plasma membrane. Despite recent advances in the understanding of Rab11-regulated mechanisms, the final steps mediating docking and fusion of Rab11-positive vesicles at the plasma membrane are not fully understood. Munc13-4 is a docking factor proposed to regulate fusion through interactions with SNAREs. In hematopoietic cells, including neutrophils, Munc13-4 regulates exocytosis in a Rab27a-dependent manner, but its possible regulation of other GTPases has not been explored in detail. Here, we show that Munc13-4 binds to Rab11 and regulates the trafficking of Rab11-containing vesicles. Using a novel Time-resolved Fluorescence Resonance Energy Transfer (TR-FRET) assay, we demonstrate that Munc13-4 binds to Rab11a but not to dominant negative Rab11a. Immunoprecipitation analysis confirmed the specificity of the interaction between Munc13-4 and Rab11, and super-resolution microscopy studies support the interaction of endogenous Munc13-4 with Rab11 at the single molecule level in neutrophils. Vesicular dynamic analysis shows the common spatio-temporal distribution of Munc13-4 and Rab11, while expression of a calcium binding-deficient mutant of Munc13-4 significantly affected Rab11 trafficking. Munc13-4-deficient neutrophils showed normal endocytosis, but the trafficking, up-regulation, and retention of Rab11-positive vesicles at the plasma membrane was significantly impaired. This correlated with deficient NADPH oxidase activation at the plasma membrane in response to Rab11 interference. Our data demonstrate that Munc13-4 is a Rab11-binding partner that regulates the final steps of Rab11-positive vesicle docking at the plasma membrane. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

In Gram-negative bacteria, most lipoproteins synthesized in the inner membrane (IM) are trafficked to the outer membrane (OM). The Lol pathway is the trafficking paradigm: LolCDE releases lipoproteins from the IM; LolA shuttles them between membranes to LolB in the OM. Several OM lipoproteins are essential for viability. In apparent concordance, the Lol proteins are each essential in wild-type cells. However, we show that Escherichia coli grows well without LolA and LolB in the absence of one...

Human trafficking as a threat for the security of member states of EU

Full Text Available The topic “Trafficking of human beings” as subject to advanced studies has been chosen due to a growing interest linked with the phenomenon in question. The study introduces a legal criminal overview of the criminal activity consisted of the recruitment, transport, transfer or reception of persons by means of force or forms of fraud for exploitation purposes. Human trafficking represents a threat for the security of member states. The trend to penetrate to all spheres of the society has obliged the European states to draft a new directive reflecting the growing concern about the phenomenon in question, by respecting human rights in accordance with the legal framework under the United Nations, International Labor Organization (ILO, and Council of Europe etc. The new European priorities aim at victims’ identification, their protection and prevention of the phenomenon and more intense criminal prosecution of traffickers. With the view of fully developing this topic, the outline consists of four chapters preceded by a historical background of human trafficking. Special importance in this study, specifically in the second chapter, is attached to the assistance and protection of the victims of human trafficking. It is crucial that these victims exercise their rights effectively. Therefore, the European directives foresee assistance and support before, after and during the criminal proceeding. The third chapter refers to the relevant legal mechanisms in this field assuring the victims of trafficking legal defense, the right to information and their social, psychological and physical recovery. One of the “key” legal instruments is the Palermo Convention, which gives for the first time a detailed definition of the term of trafficking and smuggling and makes the differences between them. All legal instruments converge to one point: the consent of the human trafficking victim is not important when it is used any of the means of force, threat

It is noted that this problem has emerged since the early 90s, when these countries got the independence, due to the difficult economic situation, activity of extremist organizations. It is pointed out that the victims of trafficking may be men, women and children, but in most cases they are young women and girls who are sexually exploited. It is shown by the examples of each of the countries of the region, what is being done to counter this terrible phenomenon. The Government of the Republic of Tajikistan established the Interdepartmental Commission to Combat Human Trafficking. The commission, in cooperation with international organizations doing some work to inform the public, the search for victims of sexual business, return and rehabilitation of these persons. In Kazakhstan, according to the new law it has become easier to initiate criminal proceedings concerning labor slavery. In addition, a temporary accommodation center for victims of human trafficking «Komek» was created. In Kyrgyzstan, a working group on the development of 3 of the National Action Plan to Combat Trafficking in Human Beings (2011-2015 under the auspices of the Ministry of Labour, Employment and Migration of the Kyrgyz Republic was created. In Uzbekistan, the law «on combating human trafficking» came into force. In addition, a Republican Interdepartmental Commission to Combat Human Trafficking was created. The law defines the powers of public authorities directly involved in the activities in this direction. In Turkmenistan, the government prohibits all forms of trafficking of persons in accordance with Article 129 of the Criminal Code, adopted in May 2010 and entered into force in July 2010. It provides for penalties ranging from 4 to 25 years in prison. These penalties sufficiently stringent and commensurate with penalties prescribed for other serious crimes, such as rape. At

While prions probably interact with the innate immune system immediately following infection, little is known about this initial confrontation. Here we investigated incunabular events in lymphotropic and intranodal prion trafficking by following highly enriched, fluorescent prions from infection sites to draining lymph nodes. We detected biphasic lymphotropic transport of prions from the initial entry site upon peripheral prion inoculation. Prions arrived in draining lymph nodes cell autonomously within two hours of intraperitoneal administration. Monocytes and dendritic cells (DCs) required Complement for optimal prion delivery to lymph nodes hours later in a second wave of prion trafficking. B cells constituted the majority of prion-bearing cells in the mediastinal lymph node by six hours, indicating intranodal prion reception from resident DCs or subcapsulary sinus macrophages or directly from follicular conduits. These data reveal novel, cell autonomous prion lymphotropism, and a prominent role for B cells in intranodal prion movement. PMID:22679554

Current means for raising efficiency of counteraction to counterfeit goods trafficking

Full Text Available The urgency of counteraction to counterfeit goods trafficking is shown. Annual loss due to counterfeit goods producing and trafficking reaches several billion dollars. There remains a danger of buying low-quality and counterfeit goods despite implementing new producing techniques and protective elements. Measures, taken by law enforcement agencies, state authorities and public human rights organizations have not led to systematic suppression of producing and trafficking of such goods. Creation of new information and reference resource, containing information blocks of protective symbols on goods and packages and illustrated materials comprising patterns of discovered counterfeit goods, can assist to increase public awareness and to give necessary information to law enforcement agencies. Organizations, realizing state and social protection of consumers and entrepreneurs, along with producers, rightholders’ representatives and law enforcement bodies can accept the responsibility of creating and functioning this information and reference system in the Internet. Such level of cooperation of all interested organizations will allow to raise efficiency of measures for counteraction to trafficking goods with violated consumer properties. The author proves the necessity to organize functioning of information and reference resource for a wide range of users. Operation of such resource should comply with main principles of generating any information resource, notably full scale, authenticity and relevance of information. The author proposes the algorithm of creating such system which provides cooperation of law enforcement agencies, producers and consumers for the purpose of preventing counterfeit goods trafficking and investigating committed crimes.

Eeyarestatin 1 interferes with both retrograde and anterograde intracellular trafficking pathways.

Directory of Open Access Journals (Sweden)

Mina-Olga Aletrari

Full Text Available The small molecule Eeyarestatin I (ESI inhibits the endoplasmic reticulum (ER-cytosol dislocation and subsequent degradation of ERAD (ER associated protein degradation substrates. Toxins such as ricin and Shiga/Shiga-like toxins (SLTx are endocytosed and trafficked to the ER. Their catalytic subunits are thought to utilise ERAD-like mechanisms to dislocate from the ER into the cytosol, where a proportion uncouples from the ERAD process, recovers a catalytic conformation and destroys their cellular targets. We therefore investigated ESI as a potential inhibitor of toxin dislocation.Using cytotoxicity measurements, we found no role for ES(I as an inhibitor of toxin dislocation from the ER, but instead found that for SLTx, ESI treatment of cells was protective by reducing the rate of toxin delivery to the ER. Microscopy of the trafficking of labelled SLTx and its B chain (lacking the toxic A chain showed a delay in its accumulation at a peri-nuclear location, confirmed to be the Golgi by examination of SLTx B chain metabolically labelled in the trans-Golgi cisternae. The drug also reduced the rate of endosomal trafficking of diphtheria toxin, which enters the cytosol from acidified endosomes, and delayed the Golgi-specific glycan modifications and eventual plasma membrane appearance of tsO45 VSV-G protein, a classical marker for anterograde trafficking.ESI acts on one or more components that function during vesicular transport, whilst at least one retrograde trafficking pathway, that of ricin, remains unperturbed.

Research on the health of trafficked men and on the health problems associated with trafficking for labor exploitation are extremely limited. This study analysed data from a case series of anonymised case records of a consecutive sample of 35 men and women who had been trafficked for labor exploitation in the UK and who were receiving support from a non-governmental service between June 2009 and July 2010. Over three-quarters of our sample was male (77 %) and two-thirds aged between 18 and 35 years (mean 32.9 years, SD 10.2). Forty percent reported experiencing physical violence while they were trafficked. Eighty-one percent (25/31) reported one or more physical health symptoms. Fifty-seven percent (17/30) reported one or more post-traumatic stress symptoms. A substantial proportion of men and women who are trafficked for labor exploitation may experience violence and abuse, and have physical and mental health symptoms.

Chung, Richard J; English, Abigail

2015-08-01

This review describes the current state of commercial sexual exploitation and sex trafficking of adolescents in the United States and globally, the legal and health implications of this severe form of abuse, and the roles that pediatric and adolescent healthcare providers can play in addressing this issue. Although this form of exploitation and abuse is shrouded in secrecy, pediatric and adolescent healthcare providers are well positioned to respond when it arises. However, awareness and understanding of the issue are generally lacking among healthcare professionals, currently limiting their effectiveness in combating this problem. Although the empirical evidence base available to guide clinical care of victims of trafficking remains limited given the secretive nature of the abuse, important contributions to the multidisciplinary literature on this issue have been made in recent years, including the Institute of Medicine's landmark report in the United States. Commercial sexual exploitation and sex trafficking of adolescents represent a human rights tragedy that remains inadequately addressed. As preeminent advocates for the health and well-being of adolescents, pediatric and adolescent healthcare providers can play a crucial role in advancing efforts not only to intervene but also to prevent further victimization of vulnerable youth.

Third hand smoke (THS) is the accumulation of second hand smoke (SHS) toxins on surfaces in homes, cars, clothing and hair of smokers. It is known that 88M US nonsmokers ≥3 years old living in homes of smokers are exposed to THS toxicants and show blood cotinine levels of ≥0.05 ng/ml, indicating that the toxins are circulating in their circulatory systems. The goal of the present study is to investigate the mechanisms by which THS causes impaired wound healing. We show that mice living under conditions that mimic THS exposure in humans display delayed wound closure, impaired collagen deposition, altered inflammatory response, decreased angiogenesis, microvessels with fibrin cuffs and a highly proteolytic wound environment. Moreover, THS-exposed mouse wounds have high levels of oxidative stress and significantly lower levels of antioxidant activity leading to molecular damage, including protein nitration, lipid peroxidation and DNA damage that contribute to tissue dysfunction. Furthermore, we show that elastase is elevated, suggesting that elastin is degraded and the plasticity of the wound tissue is decreased. Taken together, our results lead us to conclude that THS toxicants delay and impair wound healing by disrupting the sequential processes that lead to normal healing. In addition, the lack of elastin results in loss of wound plasticity, which may be responsible for reopening of wounds. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

Tracking Drug-induced Changes in Receptor Post-internalization Trafficking by Colocalizational Analysis.

Science.gov (United States)

Ong, Edmund; Cahill, Catherine

2015-07-03

The intracellular trafficking of receptors is a collection of complex and highly controlled processes. Receptor trafficking modulates signaling and overall cell responsiveness to ligands and is, itself, influenced by intra- and extracellular conditions, including ligand-induced signaling. Optimized for use with monolayer-plated cultured cells, but extendable to free-floating tissue slices, this protocol uses immunolabelling and colocalizational analysis to track changes in intracellular receptor trafficking following both chronic/prolonged and acute interventions, including exogenous drug treatment. After drug treatment, cells are double-immunolabelled for the receptor and for markers for the intracellular compartments of interest. Sequential confocal microscopy is then used to capture two-channel photomicrographs of individual cells, which are subjected to computerized colocalizational analysis to yield quantitative colocalization scores. These scores are normalized to permit pooling of independent replicates prior to statistical analysis. Representative photomicrographs may also be processed to generate illustrative figures. Here, we describe a powerful and flexible technique for quantitatively assessing induced receptor trafficking.

We have documented that epidermal growth factor receptor protein tyrosine kinase (EGFR-PTK) signaling negatively affects intracellular trafficking and transduction efficiency of recombinant adeno-associated virus 2 (AAV2) vectors. Specifically, inhibition of EGFR-PTK signaling leads to decreased ubiquitination of AAV2 capsid proteins, which in turn, facilitates viral nuclear transport by limiting proteasome-mediated degradation of AAV2 vectors. In the present studies, we observed that AAV capsids can indeed be phosphorylated at tyrosine residues by EGFR-PTK in in vitro phosphorylation assays and that phosphorylated AAV capsids retain their structural integrity. However, although phosphorylated AAV vectors enter cells as efficiently as their unphosphorylated counterparts, their transduction efficiency is significantly reduced. This reduction is not due to impaired viral second-strand DNA synthesis since transduction efficiency of both single-stranded AAV (ssAAV) and self-complementary AAV (scAAV) vectors is decreased by ~68% and ~74%, respectively. We also observed that intracellular trafficking of tyrosine-phosphorylated AAV vectors from cytoplasm to nucleus is significantly decreased, which leads to ubiquitination of AAV capsids followed by proteasome-mediated degradation, although downstream consequences of capsid ubiquitination may also be affected by tyrosine-phosphorylation. These studies provide new insights into the role of tyrosine-phosphorylation of AAV capsids in various steps in the virus life cycle, which has implications in the optimal use of recombinant AAV vectors in human gene therapy.

Bespalova, Nadejda; Morgan, Juliet; Coverdale, John

2016-02-01

Because training residents and faculty to identify human trafficking victims is a major public health priority, the authors review existing assessment tools. PubMed and Google were searched using combinations of search terms including human, trafficking, sex, labor, screening, identification, and tool. Nine screening tools that met the inclusion criteria were found. They varied greatly in length, format, target demographic, supporting resources, and other parameters. Only two tools were designed specifically for healthcare providers. Only one tool was formally assessed to be valid and reliable in a pilot project in trafficking victim service organizations, although it has not been validated in the healthcare setting. This toolbox should facilitate the education of resident physicians and faculty in screening for trafficking victims, assist educators in assessing screening skills, and promote future research on the identification of trafficking victims.

Routes of human trafficking in Europe and the position of Serbia on them

Ćopić Sanja

2008-01-01

Full Text Available Human trafficking as a form of organized crime is showing its increase today, changing at the same time its structure and characteristics. Some factors that contribute to such a situation are global trends that result in huge social and economic inequalities in the world, but also turbulences and problems that are affecting certain regions (wars, political instability, ethnic conflicts, militarization etc.. Human trafficking, as a complex social phenomenon that encompasses different forms of acting, subjects and aims, can be analyzed within different concepts. One of them refers to the issue of broader migration flows and migration control policy. Namely, from the global perspective, trafficking in human beings can be mostly considered as a form of 'organized illegal migration'. Due to that, it seems important to consider the issue of routes through which this form of migration is realized today. Discovering human trafficking routes, as well as other forms of illegal movement of people and illegal forms of trade are very important from the point of view of implementing adequate measures and relocation of resources in order to suppress these forms of socially unacceptable phenomena. Creating adequate anti-trafficking activities is important on national, regional and international levels. Keeping that in mind, the aim of this paper is to look into the contemporary routes of human trafficking within Europe and find out what is the position of Serbia on these routes, as well to examine possible changes that happened in this field during past several years. This will be done on the basis of the analysis of relevant literature, as well as on some preliminary findings of the survey on male victims of human trafficking in Serbia, which is currently conducted by the Victimology Society of Serbia.

Brucella Modulates Secretory Trafficking via Multiple Type IV Secretion Effector Proteins

2013-01-01

The intracellular pathogenic bacterium Brucella generates a replicative vacuole (rBCV) derived from the endoplasmic reticulum via subversion of the host cell secretory pathway. rBCV biogenesis requires the expression of the Type IV secretion system (T4SS) VirB, which is thought to translocate effector proteins that modulate membrane trafficking along the endocytic and secretory pathways. To date, only a few T4SS substrates have been identified, whose molecular functions remain unknown. Here, we used an in silico screen to identify putative T4SS effector candidate proteins using criteria such as limited homology in other bacterial genera, the presence of features similar to known VirB T4SS effectors, GC content and presence of eukaryotic-like motifs. Using β-lactamase and CyaA adenylate cyclase reporter assays, we identified eleven proteins translocated into host cells by Brucella, five in a VirB T4SS-dependent manner, namely BAB1_0678 (BspA), BAB1_0712 (BspB), BAB1_0847 (BspC), BAB1_1671 (BspE) and BAB1_1948 (BspF). A subset of the translocated proteins targeted secretory pathway compartments when ectopically expressed in HeLa cells, and the VirB effectors BspA, BspB and BspF inhibited protein secretion. Brucella infection also impaired host protein secretion in a process requiring BspA, BspB and BspF. Single or combined deletions of bspA, bspB and bspF affected Brucella ability to replicate in macrophages and persist in the liver of infected mice. Taken together, these findings demonstrate that Brucella modulates secretory trafficking via multiple T4SS effector proteins that likely act coordinately to promote Brucella pathogenesis.

Narco-scapes: Cocaine Trafficking and Deforestation in Central America

Wrathall, D.; McSweeney, K.; Nielsen, E.; Pearson, Z.

Narcotics trafficking and drug interdiction efforts have resulted in a well-documented social crisis in Central America, but more recently, has been tightly linked to environmental catastrophe and accelerated deforestation in transit zones. This talk will outline synthesis findings from multi-country, interdisciplinary research on cocaine trafficking as an engine of forest loss in Central America. During the "narco-boom" of the mid-2000s, we observed a geographical evolution of cocaine flows into Central America, and the transit of cocaine through new spaces, accompanied by specific patterns of social and environmental change in new nodes of transit. We coarsely estimated that the total amount of cocaine flowing through Central America increased from 70 metric tons in 2000 to 350 mt in 2012, implying that total cocaine trafficking revenue in the region increased from roughly 600 million dollars to 3.5 billion in that time. We describe the mechanism by which these locally captured cocaine rents resulted in a rapid conversion of forest into cattle pasture. Narco-traffickers are drawn to invest in the cattle economy, as a direct means of laundering and formalizing proceeds. Ranching is a land intensive activity, and new narco-enriched cattle pastures can be isolated from other forms forest loss solely by their spatial and temporal change characteristics. A preliminary forest change study in Honduras, for example, indicated that areas of accelerated deforestation were in close proximity to known narcotics trafficking routes and were thirteen times more extensive on average than other forest clearings. Deforested areas commonly appeared in isolated and biodiverse lowland tropical rainforest regions that often intersected with protected areas and indigenous reserves. We find that narco-deforestation is a readily identifiable signal of the extent and health of the cocaine economy. This talk will feature summaries of both ethnographic and land cover change we have observed

Selective cell-surface labeling of the molecular motor protein prestin

McGuire, Ryan M.; Silberg, Jonathan J.; Pereira, Fred A.; Raphael, Robert M.

2011-01-01

Highlights: → Trafficking to the plasma membrane is required for prestin function. → Biotin acceptor peptide (BAP) was fused to prestin through a transmembrane domain. → BAP-prestin can be metabolically labeled with biotin in HEK293 cells. → Biotin-BAP-prestin allows for selective imaging of fully trafficked prestin. → The biotin-BAP-prestin displays voltage-sensitive activity. -- Abstract: Prestin, a multipass transmembrane protein whose N- and C-termini are localized to the cytoplasm, must be trafficked to the plasma membrane to fulfill its cellular function as a molecular motor. One challenge in studying prestin sequence-function relationships within living cells is separating the effects of amino acid substitutions on prestin trafficking, plasma membrane localization and function. To develop an approach for directly assessing prestin levels at the plasma membrane, we have investigated whether fusion of prestin to a single pass transmembrane protein results in a functional fusion protein with a surface-exposed N-terminal tag that can be detected in living cells. We find that fusion of the biotin-acceptor peptide (BAP) and transmembrane domain of the platelet-derived growth factor receptor (PDGFR) to the N-terminus of prestin-GFP yields a membrane protein that can be metabolically-labeled with biotin, trafficked to the plasma membrane, and selectively detected at the plasma membrane using fluorescently-tagged streptavidin. Furthermore, we show that the addition of a surface detectable tag and a single-pass transmembrane domain to prestin does not disrupt its voltage-sensitive activity.

Conceptualizing child labour trafficking and exploitation: The case of Roma children in Montenegro

Directory of Open Access Journals (Sweden)

Arhin Antonela

2012-01-01

Full Text Available Trafficking of children for labour exploitation is a profit-oriented criminal activity by which children are recruited, transported, harboured or received for the purpose of labour exploitation irrespective of whether or not force, abduction, fraud or other means were used. This paper examines child labour trafficking in the context of human rights violations and as the worst form of child labour. In an attempt to situate the discourse of alleged labour exploitation and trafficking of Roma children in Montenegro, focusing in particular on instances of child begging, this paper offers an overview of the international legal framework as well as the Government of Montenegro’s policy framework relevant to this issue; an analysis of implicated historical, familial and cultural structures; and focuses on identifying root causes in terms of push-pull factors that are associated with enhancing children’s vulnerability and proneness to exploitation. Along with a set of recommendations, in closing, the paper calls for a more sophisticated analysis of child labour trafficking and, in the case of Roma children, a more nuanced understanding of historical and cultural pretexts against the backdrop of labour trafficking.

The golgin GMAP-210 is required for efficient membrane trafficking in the early secretory pathway.

Golgins are coiled-coil proteins that participate in membrane-tethering events at the Golgi complex. Golgin-mediated tethering is thought to be important for vesicular trafficking and Golgi organization. However, the degree to which individual golgins contribute to these processes is poorly defined, and it has been proposed that golgins act in a largely redundant manner. Previous studies on the golgin GMAP-210 (also known as TRIP11), which is mutated in the rare skeletal disorder achondrogenesis type 1A, have yielded conflicting results regarding its involvement in trafficking. Here, we re-investigated the trafficking role of GMAP-210, and found that it is indeed required for efficient trafficking in the secretory pathway. GMAP-210 acts at both the endoplasmic reticulum (ER)-to-Golgi intermediate compartment (ERGIC) and Golgi complex during anterograde trafficking, and is also required for retrograde trafficking to the ER. Using co-depletion experiments, we also found that GMAP-210 acts in a partially redundant manner with the golgin GM130 to ensure efficient anterograde cargo delivery to the cis-Golgi. In summary, our results indicate a role for GMAP-210 in several trafficking steps at the ER-Golgi interface, some of which are partially redundant with another golgin, namely GM130 (also known as GOLGA2). © 2015.

Cryptomarkets are online marketplaces, located on the darknet, that facilitate the trading of a variety of illegal goods, mostly drugs. While the literature essentially focus on drugs, various other goods and products related to financial or identity fraud, firearms, counterfeit goods, as well as doping products are also offered on these marketplaces. Through the analysis of relevant data collected on a popular marketplace in 2014-2015, Evolution, this research provides an analysis of the structure of trafficking (types and proportions of products, number of vendors and shipping countries). It also aims at highlighting geographical patterns in the trafficking of these products (e.g. trafficking flows, specialisation of vendors and assessment of their role in the distribution chain). The analysis of the flow of goods between countries emphasises the role of specific countries in the international and domestic trafficking, potentially informing law enforcement agencies to target domestic mails or international posts from specific countries. The research also highlights the large proportion of licit and illicit drug listings and vendors on Evolution, followed by various fraud issues (in particular, financial fraud), the sharing of knowledge (tutorials) and finally goods, currencies and precious metals (principally luxury goods). Looking at the shipping country, there seems to be a clear division between digital and physical products, with more specific information for physical goods. This reveals that the spatial analysis of trafficking is particularly meaningful in the case of physical products (such as illicit drugs) and to a lesser extent for digital products. Finally, the geographical analysis reveals that spatial patterns on Evolution tend to reflect the structure of the traditional illicit market. However, regarding illicit drugs, country-specificity has been observed and are presented in this article. Copyright © 2017 Elsevier B.V. All rights reserved.

Development of measures to deal with illicit trafficking of nuclear materials in Ghana

Full text: The world has now become a global village as such no country can isolate itself from global trends. Reported cases of illicit trafficking in nuclear materials have focused international attention on ways to combat an emerging phenomenon of the 1990's. Of the 324 confirmed cases of illicit trafficking nearly 130 involved individuals trying to illegally sell radioactive materials used in medicine or industry whose unauthorized use or movement poses a danger to public health. Some other cases have involved samples of weapons-grade materials confiscated from individuals. These incidents have raised public and governmental concerns. This has prompted stronger efforts to prevent illicit nuclear trafficking by state authorities, including collaboration and co-operation with international organizational such as the IAEA. The IAEA has established the Illicit Trafficking Database Programme and is encouraging all Member States to participate and to report all incidents of illicit trafficking in nuclear materials and other radioactive materials and other radioactive sources that come to their notice. From the data available from the Regulatory Authority Information System (RAIS), Ghana, there are 344 highly enriched uranium fuel elements (998.2g) in use in the 30kW Research Reactor, (GHARR-1) and 80 radioactive materials in use in medicine, history, research and teaching. The reactor has been subjected to safeguards inspections by IAEA on regular basis. Additionally there have been on the average about nine authorized imports of radioactive into the country in the past seven years. Unlawful use of nuclear materials, through criminal or terrorist activities, may pose a proliferation treat, while unlawful use of radiation poses risks to the public. Ghana has therefore decided to established an effective counter measure against illicit trafficking in nuclear and other materials which might pose both proliferation threat as well as radiological risk to the public and

Since the late 80's, Syria has been taking steps towards combating illicit trafficking or inadvertent movement involving radioactive or nuclear material within the country or across its border. By applying the proper combination of technical and procedural measures, an acceptable level of performance has been achieved. The measures undertaken by AECS include anticipative measures, which aim at identifying potential loss of control over radioactive sources and potential illicit trafficking within the country, as well as defensive measures which aim at detection of and response to events of illicit trafficking. In addition, a tight follow up of radiation source along their entire lifetime in the Syrian territory, supported by proper data analysis is one of the most efficient tools for identifying potential loss of control over sources. AECS has established Border Monitoring Centers (BMC) in almost all border crossings. They work in close cooperation with the customs and other relevant authorities at the Syrian borders. AECS has been also providing the necessary training for the frontline officers. (author)

2001-01-01

As it is known, for the fact that the illicit trafficking and trading of nuclear materials are being increased over the past few years because of the huge demand of third world states. Nuclear materials like uranium, plutonium, and thorium are used in nuclear explosives that have very attractive features for crime groups, terrorist groups and, the states that are willing to have this power. Crime groups that make illegal trade of nuclear material are also trying to market strategic radioactive sources like red mercury and Osmium. This kind of illegal trade threats public safety, human health, environment also it brings significant threat on world peace and world public health. For these reasons, both states and international organizations should take a role in dealing with illicit trafficking. An important precondition for preventing this kind of incidents is the existence of a strengthened national system for control of all nuclear materials and other radioactive sources. Further, Governments are responsible for law enforcement within their borders for prevention of illegal trading and trafficking of nuclear materials and radiation sources

Risk factors for mental disorders in women survivors of human trafficking: a historical cohort study

Science.gov (United States)

2013-01-01

Background Previous studies have found high levels of symptoms of depression, anxiety, and post-traumatic stress disorder among women survivors of human trafficking. No previous research has described risk factors for diagnosed mental disorders in this population. Methods A historical cohort study of women survivors of trafficked women aged 18 and over who returned to Moldova and registered for assistance with the International Organisation for Migration (IOM). Women were approached by IOM social workers and, if they gave informed consented to participate in the study, interviewed by the research team. At 2–12 months post-return to Moldova, a psychiatrist assessed DSM-IV mental disorders blind to information about women’s pre-trafficking and post-trafficking experiences using the Structured Clinical Interview for DSM-IV (SCID). A backwards stepwise selection procedure was used to create a multivariable regression model of risk factors for DSM-IV mental disorder measured at an average of 6 months post-return. Results 120/176 (68%) eligible women participated. At an average of 6 months post-return, 54% met criteria for any DSM-IV mental disorder: 35.8% of women had PTSD (alone or co-morbid), 12.5% had depression without PTSD and 5.8% had another anxiety disorder. Multivariable regression analysis found that childhood sexual abuse (Adjusted Odds Ratio [AOR] 4.68, 95% CI 1.04-20.92), increased number of post-trafficking unmet needs (AOR 1.80; 95% CI 1.28-2.52) and post-trafficking social support (AOR 0.64; 95% CI 0.52-0.79) were independent risk factors for mental disorder, and that duration of trafficking showed a borderline association with mental disorder (AOR 1.12, 95% CI 0.98-1.29). Conclusions Assessment for mental disorders should be part of re-integration follow-up care for women survivors of human trafficking. Mental disorders at that time, most commonly PTSD and depression, are likely to be influenced by a range of predisposing, precipitating and

Some 21 million adults and children are labor-trafficked or sex-trafficked through force, fraud, or coercion. In recognition of the interface between trafficking victims and the healthcare setting, over the last 10 years there has been a notable increase in training of health care professionals (HCPs) on human trafficking (HT) and its health implications. Many organizations have developed curricula and offered training in various clinical settings. However, methods and content of this education on trafficking vary widely, and there is little evaluation of the impact of the training. The goal of this study was to assess the gaps and strengths in HT education of HCPs in the US. This mixed-method study had two components. The first component consisted of structured interviews with experts in human trafficking HCP education. The second portion of the study involved an analysis of data from HCP calls to the National Human Trafficking Resource Center (NHTRC). The interviews captured trainer-specific data on types of HT training, duration and frequency, key content areas, presence of evaluation approaches and indicators, as well as an assessment of barriers and strengths in HT training for HCP. NHTRC call database analysis demonstrated increasing trends since 2008 in calls by HCPs. Overall findings revealed the need for standardization of HT training content to assure correct information, trauma-informed and patient-centered care, and consistent messaging for HCPs. Evaluation metrics for HT training need to be developed to demonstrate behavior change and impact on service delivery and patient-centered outcomes for HT victims, according to our proposed adapted Kirkpatrick's Pyramid model. HT training and evaluation would benefit from an agency or institution at the national level to provide consistency and standardization of HT training content as well as to guide a process that would develop metrics for evaluation and the building of an evidence base.

To assess health protection motivation as explained by the constructs of protection motivation theory (PMT) and its association with drug trafficking over 2 years. The sample included 817 African American youth (13-16 years old) participating in an adolescent risk-reduction program. We developed an instrument measuring the level of health protection motivation (LHPM) using factor analysis. Changes in LHPM over time were examined among drug traffickers, abstainers, initiators, and nonrisk youths. In sum, 151 participants reported selling and/or delivering drugs during the study period. The significant inverse correlation between drug-trafficking intention and health protection motivation was consistent with PMT. Changes in LHPM were strongly associated with the dynamics of behavior over 2 years. Adolescent drug trafficking can be predicted by an overall level of health protection motivation. PMT and related theories should be considered in the design of drug-trafficking prevention intervention.

Sodium 4-phenylbutyrate (4-PBA) has been shown to correct the cellular trafficking of several mutant or nonmutant plasma membrane proteins such as cystic fibrosis transmembrane conductance regulator through the expression of 70-kDa heat shock proteins. The objective of the study was to determine whether 4-PBA may influence the functional expression of epithelial sodium channels (ENaC) in human nasal epithelial cells (HNEC). Using primary cultures of HNEC, we demonstrate that 4-PBA (5 mm for 6 h) markedly stimulated amiloride-sensitive sodium channel activity and that this was related to an increased abundance of alpha-, beta-, and gamma-ENaC subunits in the apical membrane. The increase in ENaC cell surface expression (i) was due to insertion of newly ENaC subunits as determined by brefeldin A experiments and (ii) was not associated with cell surface retention of ENaC subunits because endocytosis of ENaC subunits was unchanged. In addition, we find that ENaC co-immunoprecipitated with the heat shock protein constitutively expressed Hsc70, that has been reported to modulate ENaC trafficking, and that 4-PBA decreased Hsc70 protein level. Finally, we report that in cystic fibrosis HNEC obtained from two cystic fibrosis patients, 4-PBA increased functional expression of ENaC as demonstrated by the increase in amiloride-sensitive sodium transport and in alpha-, beta-, and gamma-ENaC subunit expression in the apical membrane. Our results suggest that in HNEC, 4-PBA increases the functional expression of ENaC through the insertion of new alpha-, beta-, and gamma-ENaC subunits into the apical membrane and also suggest that 4-PBA could modify ENaC trafficking by reducing Hsc70 protein expression.

Nuclear trafficking latest statistics released

International Nuclear Information System (INIS)

2005-01-01

Full text: Countries reported 121 incidents to the IAEA in 2004 of illicit trafficking and other unauthorized activities involving nuclear and other radioactive materials, newly released statistics from the Agency's Illicit Trafficking Database (ITDB) show. The ITDB report also shows that one incident was reported since 2003 that involved fissile material - highly enriched uranium (HEU) or plutonium - that is needed to make a nuclear weapon. It occurred in June 2003 when an individual was arrested in possession of 170 grams of HEU, attempting to illegally transport it across the border. During the two-year period 2003-2004, the number of incidents reported by States substantially increased compared with previous years. 'Improved reporting may in part account for it,' the report said. 'The majority of the incidents reported in 2003-2004 showed no evidence of criminal activity.' The Past Twelve Years: 1993 - 2004 Nuclear Weapons Grade Material. Since the database started in 1993, there have been eighteen confirmed incidents involving trafficking in HEU and plutonium. A few of these incidents involved seizures of kilogram quantities of weapons-usable nuclear material but most involved very small quantities. In some of the cases the seized material was allegedly a sample of larger quantities available for illegal sale or at risk of theft. More than two dozens incidents involved trace amounts of plutonium sources. Table can be viewed: Incidents involving HEU and Pu confirmed to the ITDB (1993-2004). Nuclear Materials. In the past twelve years, 220 incidents involved nuclear materials. The majority of confirmed cases with nuclear materials involved low-grade nuclear materials, mostly in the form of reactor fuel pellets, and natural uranium, depleted uranium and thorium. While the quantities of these materials have been rather small to be significant for nuclear proliferation or use in a terrorist nuclear explosive device, these cases are indicative of gaps in the control

Radiation protection aspects of the trafficking radionuclides contaminated metal scrap

International Nuclear Information System (INIS)

Prouza, Z.

1999-01-01

This paper covers the legal base of the release in the environment of radionuclides containing materials and the radiation protection aspects of trafficking in radionuclides contaminated materials. Materials, substance and objects containing radionuclides or contaminated by them may be released into the environment, if they do not exceed values authorized by SONS (State Office of Nuclear Safety). Legislative measures should be taken against illicit trafficking of the nuclear material in all the areas. The creation of a sophisticated system for the control and regulation of all important radionuclides released into the environment should be based on the radiation protection limits, constraints, reference and exemption levels which are introduced in the legislative documents; the strong supervision of producers and users of the sealed sources by SONS side, in addition to the requirements of the licensing process of their sources; a complete data-base and information exchange system related to illicit trafficking in contaminated material; in this system all the authorities with jurisdiction should be involved. The responsibilities of the persons involved in metal scrap trafficking should include arrangement of appropriate monitoring, rules for transport of the metal scrap, an adequate measuring system to monitor metal scrap including monitoring to prevent processing or smelting of the radioactive material, control measures, etc. All of the above items of legislation are an important challenge for the Czech Republic.

A fluorescent glycolipid-binding peptide probe traces cholesterol dependent microdomain-derived trafficking pathways.

Directory of Open Access Journals (Sweden)

Steffen Steinert

Full Text Available BACKGROUND: The uptake and intracellular trafficking of sphingolipids, which self-associate into plasma membrane microdomains, is associated with many pathological conditions, including viral and toxin infection, lipid storage disease, and neurodegenerative disease. However, the means available to label the trafficking pathways of sphingolipids in live cells are extremely limited. In order to address this problem, we have developed an exogenous, non-toxic probe consisting of a 25-amino acid sphingolipid binding domain, the SBD, derived from the amyloid peptide Abeta, and conjugated by a neutral linker with an organic fluorophore. The current work presents the characterization of the sphingolipid binding and live cell trafficking of this novel probe, the SBD peptide. SBD was the name given to a motif originally recognized by Fantini et al in a number of glycolipid-associated proteins, and was proposed to interact with sphingolipids in membrane microdomains. METHODOLOGY/PRINCIPAL FINDINGS: In accordance with Fantini's model, optimal SBD binding to membranes depends on the presence of sphingolipids and cholesterol. In synthetic membrane binding assays, SBD interacts preferentially with raft-like lipid mixtures containing sphingomyelin, cholesterol, and complex gangliosides in a pH-dependent manner, but is less glycolipid-specific than Cholera toxin B (CtxB. Using quantitative time-course colocalization in live cells, we show that the uptake and intracellular trafficking route of SBD is unlike that of either the non-raft marker Transferrin or the raft markers CtxB and Flotillin2-GFP. However, SBD traverses an endolysosomal route that partially intersects with raft-associated pathways, with a major portion being diverted at a late time point to rab11-positive recycling endosomes. Trafficking of SBD to acidified compartments is strongly disrupted by cholesterol perturbations, consistent with the regulation of sphingolipid trafficking by cholesterol

KCNH2 encodes the Kv11.1 α-subunit that underlies the rapidly activating delayed-rectifier K + current in the heart. Loss-of-function KCNH2 mutations cause long QT syndrome type 2 (LQT2), and most LQT2-linked missense mutations inhibit the trafficking of Kv11.1 channel protein to the cell surface membrane. Several trafficking-deficient LQT2 mutations (e.g., G601S) generate Kv11.1 proteins that are sequestered in a microtubule-dependent quality control (QC) compartment in the transitional endoplasmic reticulum (ER). We tested the hypothesis that the QC mechanisms that regulate LQT2-linked Kv11.1 protein trafficking are mutation-specific. Confocal imaging analyses of HEK293 cells stably expressing the trafficking-deficient LQT2 mutation F805C showed that, unlike G601S-Kv11.1 protein, F805C-Kv11.1 protein was concentrated in several transitional ER subcompartments. The microtubule depolymerizing drug nocodazole differentially affected G601S- and F805C-Kv11.1 protein immunostaining. Nocodazole caused G601S-Kv11.1 protein to distribute into peripheral reticular structures, and it increased the diffuse immunostaining of F805C-Kv11.1 protein around the transitional ER subcompartments. Proteasome inhibition also affected the immunostaining of G601S- and F805C-Kv11.1 protein differently. Incubating cells in MG132 minimally impacted G601S-Kv11.1 immunostaining, but it dramatically increased the diffuse immunostaining of F805C-Kv11.1 protein in the transitional ER. Similar results were seen after incubating cells in the proteasome inhibitor lactacystin. Differences in the cellular distribution of G601S-Kv11.1 and F805C-Kv11.1 protein persisted in transfected human inducible pluripotent stem cell derived cardiomyocytes. These are the first data to visually demonstrate mutation-specific differences in the trafficking-deficient LQT2 phenotype, and this study has identified a novel way to categorize trafficking-deficient LQT2 mutations based on differences in intracellular

Organ economy: organ trafficking in Moldova and Israel.

Lundin, Susanne

2012-02-01

Organ trafficking is an illegal means of meeting the shortage of transplants. The activity flourishes for several interacting reasons, such as medical needs, poverty and criminality. Other factors are fundamental conceptual structures such as the dream of the regenerative body as well as the view of the body as an object of utility and an object of value. The article aims to go behind the normative discussions that usually surround organ trafficking. Why this is happening, and what the societal consequences are, is examined through ethnographic fieldwork. The focus is on the shadow economies that govern existence and in which people, goods, weapons, money, bodies, etc. constitute components of the global market.

Physical protection as the most important part of the national system of combating illicit trafficking

International Nuclear Information System (INIS)

Mishchenko, V.

2002-01-01

Full text: It is now obvious today that illicit trafficking, including its most dangerous manifestations proliferation of nuclear weapons, smuggling of nuclear materials and equipment - present a serious threat to the international community. To defeat this evil is possible only by joint efforts, by undertaken protective measures on national and international level. Joint efforts should be directed at fulfilling three main tasks as follows: safe and reliable handling of nuclear material, effective measures of its physical protection, accountancy and control in order to prevent proliferation; joint activities of intelligence customs and law-enforcement authorities directed at prevention of international trafficking and marketing of stolen goods; joint activities directed at identification and prevention of illegal supply and demand of fissionable materials counteracting thereby various criminal structures. In order to solve these problems an international regime should be established. Such regime will define a number of criteria and demands to be met by-the states to ensure effective combat illicit trafficking. The international regime should be based on national systems of combating illicit trafficking, which include measures for prevention, detection and response regarding illicit trafficking in each specific state of across its borders. When undertaking these measures one should take into account specific characteristics of the state, its unique features and its geography, political and economic situation, as well as different types of potential threat of proliferation of nuclear weapons; availability of materials subjected to illicit trafficking in this state, general situation of criminal trafficking in this state, general situation of criminal trafficking with radioactive materials, potential consumers and suppliers, market features, possible incentives for crime etc. In the paper I would like to reflect the vital components of national systems for combating

The CFTR-Associated Ligand Arrests the Trafficking of the Mutant ΔF508 CFTR Channel in the ER Contributing to Cystic Fibrosis

Directory of Open Access Journals (Sweden)

Emily Bergbower

2018-01-01

Full Text Available Background/Aims: The CFTR-Associated Ligand (CAL, a PDZ domain containing protein with two coiled-coil domains, reduces cell surface WT CFTR through degradation in the lysosome by a well-characterized mechanism. However, CAL’s regulatory effect on ΔF508 CFTR has remained almost entirely uninvestigated. Methods: In this study, we describe a previously unknown pathway for CAL by which it regulates the membrane expression of ΔF508 CFTR through arrest of ΔF508 CFTR trafficking in the endoplasmic reticulum (ER using a combination of cell biology, biochemistry and electrophysiology. Results: We demonstrate that CAL is an ER localized protein that binds to ΔF508 CFTR and is degraded in the 26S proteasome. When CAL is inhibited, ΔF508 CFTR retention in the ER decreases and cell surface expression of mature functional ΔF508 CFTR is observed alongside of enhanced expression of plasma membrane scaffolding protein NHERF1. Chaperone proteins regulate this novel process, and ΔF508 CFTR binding to HSP40, HSP90, HSP70, VCP, and Aha1 changes to improve ΔF508 CFTR cell surface trafficking. Conclusion: Our results reveal a pathway in which CAL regulates the cell surface availability and intracellular retention of ΔF508 CFTR.

Illicit trafficking of nuclear and other radioactive material: the 'net' security threat

Full text: Illicit trafficking in nuclear and other radioactive material, which could lead to the creation of a nuclear device or a radiological dispersal device (RDD), has been a subject of concern for more than a decade now. This concern became even more pronounced after the September 11 th attacks in the United States, which demonstrated that modern day terrorists are willing and capable of inflicting mass casualties among civilian population in target countries in order to further their goals. The problem of illicit trafficking - intentional diversion and smuggling of nuclear fissile material and radioactive sources - has been closely watched and studied by several national institutions and international organizations. This resulted in the establishment of several nuclear smuggling databases, tracking illicit trafficking incidents. The number of such incidents for a given period varies widely between the different databases, reflecting the different sources of information used, the different geographical regions covered, as well as the different methodologies applied to data mining and data analysis. One major obstacle to assessing the actual security threat due to illicit trafficking is the inclusion of incidents in the analysis, which do not represent a security threat in the sense of being the pre-stage of a terrorist operation or a malevolent act. Such incidents mainly involve inadvertent movement of illegally disposed of radioactive sources in scrap metal or contaminated goods across international borders and discoveries of so called 'orphan' radiation sources. This paper analyzes the global data contained in the database on nuclear smuggling, theft and orphan radiation sources (DSTO) operated by the University of Salzburg, using special filters to discriminate between illicit trafficking incidents involving a criminal intent and those that do not. Thereby, the net security threat of illicit trafficking will be determined to help provide a realistic

Human trafficking, labor brokering, and mining in southern Africa: responding to a decentralized and hidden public health disaster.

Science.gov (United States)

Steele, Sarah

2013-01-01

Many southern African economies are dependent on the extractive industries. These industries rely on low-cost labor, often supplied by migrants, typically acquired through labor brokers. Very little attention has so far been paid to trafficking of men into extractive industries or its connection with trafficked women in the region's mining hubs. Recent reports suggest that labor-brokering practices foster human trafficking, both by exposing migrant men to lack of pay and exploitative conditions and by creating male migratory patterns that generate demand for sex workers and associated trafficking of women and girls. While trafficking in persons violates human rights, and thus remains a priority issue globally, there is little or no evidence of an effective political response to mine-related trafficking in southern Africa. This article concludes with recommendations for legal and policy interventions, as well as an enhanced public health response, which if implemented would help reduce human trafficking toward mining sites.

Acting in Isolation: Safeguarding and anti-trafficking officers' evidence and intelligence practices at the border

Directory of Open Access Journals (Sweden)

Jennifer K. Lynch

2017-04-01

Full Text Available Internationally, the border has been presented as a site of unique opportunity for the identification and protection of victims of human trafficking. In the UK, the establishment of specialist safeguarding and anti-trafficking (SAT units within the border force has raised questions about the challenges for border force officers (BFOs of balancing the enforcement of strict immigration rules with the protection of victims under anti-trafficking legislation. In this paper we draw on data collected from a study of anti-trafficking initiatives at Heathrow airport to consider a particular area of BFO frustration with SAT work: the collection and use of evidence and intelligence to support investigation and pursuit of potential SAT cases at the border. Our findings focus on the use of intelligence and data to inform initiatives and develop a comprehensive understanding of the trafficking problem; and the scope of BFO powers of evidence-collection on the frontline. The experience of BFOs points to a team often working in isolation as they attempt to traverse gaps in data collection and limits to their powers to gather evidence in pursuit of their duty to identify victims of trafficking at the UK border. We conclude by making proposals for how the border force and central government could improve evidence and intelligence practices in ways that translate into both more coherent anti-trafficking policy and better identification and support for victims.

KSHV Entry and Trafficking in Target Cells—Hijacking of Cell Signal Pathways, Actin and Membrane Dynamics

2016-11-01

Full Text Available Kaposi’s sarcoma associated herpesvirus (KSHV is etiologically associated with human endothelial cell hyperplastic Kaposi’s sarcoma and B-cell primary effusion lymphoma. KSHV infection of adherent endothelial and fibroblast cells are used as in vitro models for infection and KSHV enters these cells by host membrane bleb and actin mediated macropinocytosis or clathrin endocytosis pathways, respectively. Infection in endothelial and fibroblast cells is initiated by the interactions between multiple viral envelope glycoproteins and cell surface associated heparan sulfate (HS, integrins (α3β1, αVβ3 and αVβ5, and EphA2 receptor tyrosine kinase (EphA2R. This review summarizes the accumulated studies demonstrating that KSHV manipulates the host signal pathways to enter and traffic in the cytoplasm of the target cells, to deliver the viral genome into the nucleus, and initiate viral gene expression. KSHV interactions with the cell surface receptors is the key platform for the manipulations of host signal pathways which results in the simultaneous induction of FAK, Src, PI3-K, Rho-GTPase, ROS, Dia-2, PKC ζ, c-Cbl, CIB1, Crk, p130Cas and GEF-C3G signal and adaptor molecules that play critical roles in the modulation of membrane and actin dynamics, and in the various steps of the early stages of infection such as entry and trafficking towards the nucleus. The Endosomal Sorting Complexes Required for Transport (ESCRT proteins are also recruited to assist in viral entry and trafficking. In addition, KSHV interactions with the cell surface receptors also induces the host transcription factors NF-κB, ERK1/2, and Nrf2 early during infection to initiate and modulate viral and host gene expression. Nuclear delivery of the viral dsDNA genome is immediately followed by the host innate responses such as the DNA damage response (DDR, inflammasome and interferon responses. Overall, these studies form the initial framework for further studies of

Aberdein, Charlotte; Zimmerman, Cathy

2015-01-01

Emerging evidence indicates the extreme forms of violence and acute and longer-term mental health consequences associated with trafficking and exploitation. However, there has been little research on post-trafficking mental health and psychosocial support services for survivors. This study explored the availability and accessibility of mental health and psychosocial support services in Cambodia for women, men and children trafficked and exploited for sex or labour purposes. Semi-structured interviews were conducted with a purposively selected sample of representatives from seven service organizations providing mental health and psychosocial support services for people who have been trafficked. This qualitative method was selected to gain insights into the service approaches and challenges faced by the small number of post-trafficking service providers in Cambodia. A conceptual framework outlining access dimensions associated with service provision guided the structure of the study. Findings indicate that among the available post-trafficking services, there are few trained mental health specialists, an over-representation of shelter services in urban versus rural areas and limited services for males, people with disabilities, individuals exploited for labour (versus sexual exploitation) and those with more serious mental illnesses. Providers believe that discrimination and stigma related to both mental health and human trafficking hinder trafficked people's willingness to access services, but suggest that awareness-raising may reduce these prejudices. Care in this sector is precarious due to over-reliance on financial support by donors versus government. Recent increases in newly qualified professionals and providers suggest potential improvements in the quality and availability of psychological support for trafficking survivors. Psychological support for the growing number of identified trafficking survivors in Cambodia will depend on improved geographical

Human trafficking is a global problem and results in deleterious psychological, social, and physical effects on the lives of those who are trafficked; however, it is not clear how to best intervene with survivors. The purpose of this review was to synthesize the evidence of exit and postexit intervention programs for survivors of human trafficking to inform practice and research. Systematic review methods were used to search, select, and extract data from published and unpublished experimental, quasi-experimental, and preexperimental studies that assessed the effects of any exit or postexit interventions for victims of human trafficking. The authors searched eight databases, reviewed bibliographies, and conducted forward citation searches from relevant reports and prior reviews to find studies authored between 2005 and 2015. The search yielded six eligible studies that included 155 female and 6 male survivors from four countries. Interventions were diverse, with three using a trauma-informed approach. Authors measured a myriad of outcomes, including mental health, social network, community reintegration, and employment; however, the quality of most studies was poor. Evidence of effects of exit and postexit interventions is sparse, and much of the research is poorly designed and executed; however, the needs of trafficking survivors are complex and effective interventions are desperately needed. Implications for practice and research are discussed.

Protein trafficking and maturation regulate intramembrane proteolysis.

Science.gov (United States)

Morohashi, Yuichi; Tomita, Taisuke

2013-12-01

Intramembrane-cleaving proteases (I-CLiPs) are membrane embedded proteolytic enzymes. All substrates identified so far are also membrane proteins, involving a number of critical cellular signaling as well as human diseases. After synthesis and assembly at the endoplasmic reticulum, membrane proteins are exported to the Golgi apparatus and transported to their sites of action. A number of studies have revealed the importance of the intracellular membrane trafficking in i-CLiP-mediated intramembrane proteolysis, not only for limiting the unnecessary encounter between i-CLiPs and their substrate but also for their cleavage site preference. In this review, we will discuss recent advances in our understanding of how each i-CLiP proteolysis is regulated by intracellular vesicle trafficking.

Alcohol-induced defects in hepatic transcytosis may be explained by impaired dynein function.

Science.gov (United States)

Groebner, Jennifer L; Fernandez, David J; Tuma, Dean J; Tuma, Pamela L

2014-12-01

Alcoholic liver disease has been clinically well described, but the molecular mechanisms leading to hepatotoxicity have not been fully elucidated. Previously, we determined that microtubules are hyperacetylated and more stable in ethanol-treated WIF-B cells, VL-17A cells, liver slices, and in livers from ethanol-fed rats. From our recent studies, we believe that these modifications can explain alcohol-induced defects in microtubule motor-dependent protein trafficking including nuclear translocation of a subset of transcription factors. Since cytoplasmic dynein/dynactin is known to mediate both microtubule-dependent translocation and basolateral to apical/canalicular transcytosis, we predicted that transcytosis is impaired in ethanol-treated hepatic cells. We monitored transcytosis of three classes of newly synthesized canalicular proteins in polarized, hepatic WIF-B cells, an emerging model system for the study of liver disease. As predicted, canalicular delivery of all proteins tested was impaired in ethanol-treated cells. Unlike in control cells, transcytosing proteins were observed in discrete sub-canalicular puncta en route to the canalicular surface that aligned along acetylated microtubules. We further determined that the stalled transcytosing proteins colocalized with dynein/dynactin in treated cells. No changes in vesicle association were observed for either dynein or dynactin in ethanol-treated cells, but significantly enhanced dynein binding to microtubules was observed. From these results, we propose that enhanced dynein binding to microtubules in ethanol-treated cells leads to decreased motor processivity resulting in vesicle stalling and in impaired canalicular delivery. Our studies also importantly indicate that modulating cellular acetylation levels with clinically tolerated deacetylase agonists may be a novel therapeutic strategy for treating alcoholic liver disease.
