subjects: community participation

abstract: The purpose of this review is to create a set of provisional criteria for Institutional Review Boards (IRBs) to refer to when assessing the ethical orientation of transgender health research proposals. We began by searching for literature on this topic using databases and the reference lists of key articles, resulting in a preliminary set of criteria. We then collaborated to develop the following nine guidelines: (1) Whenever possible, research should be grounded, from inception to dissemination, in a meaningful collaboration with community stakeholders; (2) language and framing of transgender health research should be non-stigmatizing; (3) research should be disseminated back to the community; (4) the diversity of the transgender and gender diverse (TGGD) community should be accurately reflected and sensitively reflected; (5) informed consent must be meaningful, without coercion or undue influence; (6) the protection of participant confidentiality should be paramount; (7) alternative consent procedures should be considered for TGGD minors; (8) research should align with current professional standards that refute conversion, reorientation, or reparative therapy; and (9) IRBs should guard against the temptation to avoid, limit, or delay research on this subject.

title: The effects of honey on the inflammatory response of cells with respect to wound healing

authors: Harcourt, Nichola Robyn

abstract: The primary aim of this thesis was to test the effect of two types of honey, a manuka honey and an Otago pasture honey, on a range of key cell types involved in the inflammatory response of wound healing. A range of in vitro assays were used to test the effect of honey on various cells with a view to the implications of the results for wound healing, focusing on the mechanisms by which honey has been observed to have beneficial effects on both scar formation and inflammation. 
To investigate whether honey could stimulate bovine T cells to proliferate in vitro, both MTT and BrDU assays of proliferation and flow cytometry analysis were used. It was found that low concentrations of honey stimulated resting T cells to proliferate and express the IL-2 receptor in a dose-dependent manner with progressive dilution. This suggests that honey contains lymphomitogenic factors. Manuka honey was stimulatory at higher dilutions than pasture honey. Low concentrations of honey induced cell division profiles similar to those obtained with Con A-stimulated cells. The stimulatory activity of honey was found to be in a high molecular weight fraction. Sugars alone had no effect on T cell proliferation, as demonstrated by use of artificial honey (a syrup of sugars as in honey). 
The ability for honey to induce messenger RNA expression for key cytokines involved in wound healing was investigated. Conventional reverse transcriptase-PCR was used to detect the production of mRNA for honey at 0.25% concentrations for various times (0-24 h). The more sensitive molecular technique, quantitative real-time RT-PCR was then used to quantify the abundance of cytokine mRNA transcripts expressed in bovine blood exposed to 0.25% manuka honey as compared with Con A or control cultures. Transcriptional activity of ten genes, IL-1, IL-5, IL-12, IL-18, IFN-𝛾, HSP70, HSP90, iNOS, TNF-α, and TGF-β were studied at the mRNA level during a 0-24 h exposure of whole blood to honey. To test for any modulatory effects of honey on gene expression in an inflammatory model, whole blood was exposed to honey at the same time as LPS and the mRNA expression for the genes was measured. The results show that honey upregulates a wide range of mediators, including TNF-α, IL-1β, and TGF-β, and this supports the hypothesis that honey induces cytokine release. Honey gave a transient and moderate induction of cytokine mRNA compared with a massive and prolonged induction by the mitogens, Con A and LPS. The inclusion of honey with LPS led to a reduced expression of mRNA for key inflammatory mediators, including iNOS and TGF-β, compared with LPS alone. This supports the hypothesis that honey modulates inflammation. 
To investigate whether honey could induce THP-1 monocytes to release TNF-α, bioassays using WEHI cells were carried out to measure TNF-α production after the monocytes were exposed to honey. Honey was found to stimulate release of TNF-α by the monocytes when at a range of concentrations between 0.000025-0.1%, with no differences between the levels produced at the various concentrations of honey. At concentrations of honey from 0.25-1% the TNF-α production decreased as the concentration of honey increased. This may indicate that an anti-inflammatory action overrides the stimulatory effect at concentrations of honey greater than 0.25%. Sugar content had no effect upon TNF-α release, as demonstrated by the artificial honey control. There were no differences between honey types (manuka honey and pasture honey) in induction of TNF-α release. Time-course analysis confirmed that a 4-6 h incubation period of cells with 0.25% honey gave maximal TNF-α production. A 2 h minimum exposure period of cells to honey was critical for TNF-α production. Incubation of LPS-stimulated monocytes with honey had no effect on their subsequent TNF-α production. A good correlation was found between the TNF measurements detected by ELISA and the WEHI Bioassay. 
To test whether honey could modulate LPS-stimulated NO production by THP-1 monocytes and bovine peripheral blood mononuclear cells, Greiss assays were performed. Both manuka honey and pasture honey at 0.5% and 1% concentrations suppressed LPS-induced nitrite release in a dose-wise manner, indicating modulation of nitric oxide production. Manuka honey had a more potent modulating effect on LPS driven nitrite production than pasture honey, and maintained activity at 0.25%. Sugars alone had no effect. High molecular weight dialysis fractions of either honey contained the activity, but some of the activity was lost by fractionation. An ether extract of manuka honey led to the greatest modulation of nitrite production by LPS-stimulated monocytes.  
To investigate whether honey has an effect on phagocytosis, whole blood was incubated with honey and the ability of neutrophils to take up fluorescent-labelled bacteria was measured using the Phagotest® assay. The artificial honey control provided clear evidence that low concentrations of honey (optimal at 0.25%) induce phagocytosis by neutrophils due to the supply of sugars. Manuka honey had an additional opsonizing effect on bacteria, which enhances the phagocytic response beyond that seen with sugars alone. 
The effects of honey on tight junction (TJ) resistance were assessed for MDCK cell monolayers subjected to an EGTA challenge. It was found that manuka honey and pasture honey have protective effects on TJ following the challenge, and enhance postchallenge recovery of transepithelial resistance. Manuka honey had greater modulatory activity on TJ with increased concentration from 0.1-1%, and 1% concentrations of both honeys gave the greatest protective effects. Manuka honey appeared to have greater protective effects than pasture honey. Application of manuka honey (at 1% concentrations) to both the apical and basolateral sides of the MDCK cell monolayer significantly enhanced TJ tightness beyond the control. Dialysis of the honey confirmed that the high molecular weight fraction contained the active component. Diffusate fractions from either honey type had no effect on TJ. Artificial honey had no effect. 
The effect of various honey concentrations on the proliferation of the 3T3-Ll fibroblast cell-line in vitro was investigated using MTT proliferation assays. Both manuka honey and pasture honey (0.25%) increased fibroblast proliferation. Artificial honey had no effect on fibroblast proliferation, indicating sugars have no role in mitogenic activity. This suggests that honey contains factors which directly promote cell division in fibroblasts. 
An in vitro model was used to test whether honey-induced factors produced by peripheral blood mononuclear cells (PBMC) could activate fibroblast proliferation. These assays were performed to examine whether honey could have an indirect stimulatory effect on fibroblasts. Incubating fibroblasts with supernatants derived from honey-stimulated PBMCs (at 0.025% concentrations of honey) led to significant fibroblast proliferation. Low concentrations of honey (less than 0.1%) do not directly stimulate fibroblast proliferation, therefore factors produced by honey-stimulated PBMCs must promote fibroblast proliferation. A high molecular weight fraction of manuka honey obtained from dialysis contained the active component. The diffusate obtained by dialysis (containing sugars) had no activity. 
To investigate whether honey could modulate the response of fibroblasts to an inflammatory agent, fibroblasts were exposed to honey for various times prior to and at the same time as IL-1β. Honey did not augment fibroblast proliferation when added at the same time as IL-1β. Prior incubation of fibroblasts with honey (0.25-1%) for 2 h before IL-1β-stimulation decreased the cell response to IL-1β, and this anti-inflammatory active component was of a high molecular weight.
It is proposed, on the basis of this in vitro study, that honey provides a neatly controlled therapy for optimising tissue repair, with potential for use in inflammatory disorders. It is the central thesis of this study that the stimulatory agent in honey induces cytokine production necessary for healing to occur, but that the oxidant species produced by these cells are effectively regulated by a second agent, thereby creating a feedback-regulated delivery system. The results presented in the current study suggest that honey can both stimulate and modulate cell activity, and show that honey interferes with a large number of regulatory steps in the inflammatory pathway, e.g. cell division, transcription, tight junction integrity, production of oxidant species. While the stimulatory activity was observed at lower concentrations, the modulatory effects required higher concentrations of honey. The dual ability for honey to stimulate moderate cellular activation in the absence of an immune stimulus, yet not augment mitogenic stimulation, and in some cases to modulate cell response to a mitogen, indicates that it will promote healing without setting up harmful inflammation. 
If further experiments confirm this to be the case, honey will have potential for therapeutic application. The work also identifies some new areas of research, which if completed would further enhance the understanding of the role honey plays in tissue healing.

title: A Case for an Indigenous Court - a realisation of self-determination?

authors: Toki, Valmaine

subjects: Indigenous

abstract: This thesis searches for appropriate ways to alter entrenched patterns of highly negative outcomes for Māori in the criminal justice system. The statistics demonstrate that proportionately, Māori are much more likely to be apprehended, arrested, prosecuted, convicted and incarcerated than other New Zealanders and ethnic groups, and much less likely to be granted parole. 

An overview of the current relationship between Māori and the criminal justice system provides a background to begin understanding these long-standing patterns. An examination of the ancestral conceptions of tikanga Māori, including issues of proper conduct, punishment, behaviour and attaining balance, provides a persuasive framework to positively transform the criminal justice system. In order to understand why tikanga Māori is not meaningfully realised today, an historical review of the introduction of English law and legal systems clarifies the negative and almost fatal impact English law had on tikanga Māori. 

An evaluation of two instruments — Treaty of Waitangi and the United Nations Declaration on the Rights of Indigenous Peoples — provides further context for this dialogue. A specific focus on the right to culture and the right of self-determination, within these two documents, highlights the need to meaningfully revisit and/or realise these rights as a pathway to recognise the concepts of tikanga Māori. A review of comparative jurisdictions indicates existing support for the right to culture and the right of self-determination within respective legal systems and constitutions. 

An examination of the current criminal justice initiatives and policies in New Zealand highlights the status quo. This current status quo is set against initiatives in comparative jurisdictions. Following a domestic and international analysis, models underpinned by therapeutic jurisprudence and tikanga Māori, are suggested as a potential way forward for Māori to realise a form of self-determination.


In conclusion, new frameworks are proposed. These may provide an opportunity to apply the philosophy of Te Ao Māori, realised by an indigenous legal system, manifested by an indigenous court premised on fundamental Māori concepts and doctrine as the most promising way forward for Māori to ameliorate the disproportionate offending rates. A suggested extension to the Māori Land Court to include a criminal jurisdiction or, alternatively, a Tikanga Court is proposed.
